     None of those patents disclose a cabinet or any other type of container, housing, or apparatus, which is hinged to the same hinges that support a door on a door frame, so that the cabinet or other device is pivotable relative to the door, and can be positioned relative to the door so that the cabinet or other device is closed by the door in one position relative to the door, and is pivotally movable relative to the door to provide access into the cabinet or other device. Nor do they show any such devices mounted on hinges that are mounted on a wall. 
     BRIEF SUMMARY OF THE INVENTION 
     A cabinet or other similar device, hereinafter referred to as a cabinet, has hinge sections that are supported on the hinges of a door hung in a doorway. The cabinet has one pivotal position relative to the doorway door wherein access to the interior of the cabinet is provided, and has another pivotal position relative to said door wherein access to the interior of the cabinet wherein access to the interior of the cabinet is closed. The cabinet hinge sections may be that of a double hinge where a first part is hinged to a second part by a single hinge pin, and the second part is hinged to a third part which, in turn, is hinged via a double hinge pin to a part of the original door hinge. This multi-sectioned cabinet hinge permits the cabinet to be pivotally moved about the axis of the double hinge pin relative to the door that is still hinged to the door frame, and at any point may also be pivotally moved about the single hinge pin, permitting the cabinet to be moved through an arc that is about 135° from the cabinet&#39;s closed position in which the door also covers the open side of the cabinet, making the items in the cabinet on the cabinet shelves more readily available. 
     There may be a single cabinet that is pivotally moved to a position where the door has a surface that engages the single cabinet and blocks access to the cabinet interior. The cabinet may have sides that are beveled so that the back is wider than the front, with the front preferably being positioned so that the beveling is at equal angles. This permits the cabinet to be moved to and beyond its 90° fully open position when the sides are not beveled, which is only about 90° from the plane of the door surface  430 , the fully open position being some 20° to 30° or more greater than the 90° maximum when the cabinet is shaped as a rectangular box having equal dimensions for the closed back side and the open front side. There may be two cabinets hinged to be immediately adjacent to each other with the door side adjacent the cabinets still being the cover for the open cabinet front when the cabinet is closed against that door side. Separate cabinets may be positioned on the opposite sides of a door, providing cabinet storage space to two rooms which have the door as a common access between them. Of course, since the door is hinged on only one vertical portion of the door frame, the positions of the cabinet hinge portions relative to the other door side will be reversed. 
     One of the features of the invention is a set of hinge parts for at least two door hinge pins has only two sections, one of which is secured to the side of the cabinet, and the other side is secured to the door frame. A modification of this feature is the double hinged hinges described above. In all instances, there is a common feature of either type of hinge construction, namely that the hinge sections that are secured to a cabinet side are adjustably mounted on the cabinet and have connections, either directly or indirectly through the middle hinge section of the two hinge arrangement, to the hinge pins of the door, so that the cabinet is pivotally supported by the fixed hinge parts serving the door, including the hinge pins. More particularly, the hinge pins each have the usual part that extends through openings in both sections of the door hinges and has another part that is above that usual part, or is below that usual part, separated by a circumferentially enlarged pin head, so that the pin head rests on top of the stationary parts of the door hinges of all the door hinges. At times, it is desirable for only the top cabinet hinge part to be in supporting engagement with the head of the double hinge pin, and the lower cabinet hinge having its hinge part positioned underneath the stationary parts of the door hinges. In this arrangement, the cabinet hinge parts connection to the hinge pins of the door are arranged so that the cabinet hinge lower surfaces are not supported against the pin heads, but are still rotationally guided by the door pins, When it is desirable to easily remove the cabinet from the door without pulling out any hinge pin, all of the cabinet hinge sections that fit around the cabinet hinge pin must fit on the upper end of that pin and be supported by the pin head that separates the upper and lower parts of the hinge pin, thus allowing the cabinet to be removed and replaced without having to take any of the door hinges apart. 
     Another feature is the arrangement of the shelving within the cabinet to house some relatively unusual items, such as rolls of wrapping paper and accessories for wrapping packages, as well as the tools needed. A cabinet can be provided with a fold-down work space, which may be used for study, reading, sewing, working on arts and crafts, drafting, ironing clothes, or whatever such a work space is needed. Since the work space folds up to be just inside the cabinet, it also acts as a cover. The exterior of the cabinet back side may have a mirror installed on it. It may be a long length mirror for ladies&#39; or gentlemen&#39;s dressing, or a shorter mirror which can be easily seen for ladies brushing their hair and using cosmetics. Such mirrors would be available at all times when the cabinet is closed. The invention also includes similar mirrors that go with the cabinet when the mirrors are mounted on a wall and the cabinet is mounted on a hinged frame also mounted on the wall. Depending upon the available room along a wall, and the desires of the person who will be using the room, the hinged frame may be alongside one vertical edge of a mirror mounted on the wall, or may itself be mounted on that hinged frame using hinges that are a part of the invention, so that the mirror is also movable in the manner of a door, as is the cabinet, mounted on hinges secured to that same frame or on an adjacent hinged frame on which the cabinet is mounted on hinges secured to that adjacent hinged frame. 
     Still another feature of at least one of the cabinets of the invention is that the outer wall of the cabinet, sometimes referred to as its back side, is curvilinear about a substantially vertical axis so that the outer wall of the cabinet forms a vertically extending arc of a cylinder whose axis is remote from the arcuate-sectioned cabinet, with the shelves in the cabinet being similar to arcuate slices of a shelf having a cylindrical arcuate surface that is engaged with the inner surface of the cabinet outer wall. It may also be curvilinear about different axes to vary the amount of curvature in various parts of it. 
     It is also a feature of the invention to have a mirror, preferably a mirror of sufficient length to use when dressing, that is either a part of the cabinet, located on the outside of the cabinet, or also separately hinged, along with the cabinet and the door, so that it can also function as a closure for some or all of the storage areas within the cabinet, and can be swung on the hinges to provide access to such storage areas, yet when it is desired to use the mirror with the cabinet being positioned well arcuately away from the door which is also mounted on the same set of hinges, by just closing the mirror to close the cabinet storage areas. 
    
    
     
       BRIEF DESCRIPTION OF THE SEVERAL FIGURES OF THE DRAWING 
         FIG. 1  is a perspective view of a cabinet embodying the invention, before the hinge parts connecting it to the hinges of a door are installed on it. 
         FIG. 2  is a front elevation view of the cabinet of  FIG. 1 , showing the hinge parts connecting it to the hinges of a door are installed on the cabinet. 
         FIG. 3  is a side elevation view of one side of the cabinet of  FIGS. 1 and 2 , taken in the direction of arrows  3 - 3  of  FIG. 2 , on which the hinge parts connecting it to the hinges of a door are installed on the cabinet. 
         FIG. 4  is a side elevation view of the other side of the cabinets of  FIGS. 1 and 2 , taken in the direction of arrows  4 - 4  of  FIG. 2 . 
         FIG. 5  is a perspective view of a typical door that provides access between two rooms, the door being mounted on hinges pivotally attaching the door to its door frame, including at least two of the hinges on which a cabinet such as that shown in  FIGS. 1-4  can also be mounted. A modified cabinet embodying the invention is installed on the door, and is shown opened. Some of this cabinet&#39;s versatility is shown. By example, it has a workplace that is folded out to work on its surface, and folded in to cover a part of the cabinet storage area. It also shows the vertical sides of the modified cabinet being beveled inwardly from the front edges of those sides as they extend further from the cabinet front side, rendering the back edges of the two cabinet vertical sides to be closer to each other than are the front edges of those same cabinet vertical sides, allowing the bevel-sided cabinet to be opened greater than 90°. 
       FIGS.  6  and  8 - 10  are somewhat simplified illustrations showing one of the shelves connected to the two sides of the cabinet when the cabinet has a curvilinear back side as later shown in  FIGS. 11 ,  12  and  13 . 
         FIG. 6  is a cross-section view taken in the direction of arrows  6 - 6  of  FIG. 12 . The curvilinear back side of the cabinet is formed on an arc of a circle and therefore has a constant radius. 
         FIG. 7  is an elevation view of one of the sides of a cabinet taken in the direction of arrows  7 - 7  of  FIG. 6 , with parts broken away. 
         FIG. 8  is similar to  FIG. 6 , showing the curvilinear cabinet back side formed on either side on an arc having a short radius, with the portions connecting these side arcs being formed on an arc having a much longer radius, resulting in a curved back and the shelf shown being made using such different arcs. 
         FIG. 9  is similar to  FIG. 8 , but with the small radius arcs having a somewhat longer radius, and the larger radius arc having a radius that is smaller than the radius of the larger arc of  FIG. 8 . The effect is the provision of a larger shelf area than the configurations shown in  FIGS. 6 and 8 . 
         FIG. 10  is similar to  FIGS. 8 and 9 , but has the shelf arc (and therefore the arc of the cabinet curvilinear back side) created by continuously changing arc radii which are short at each end of the shelf and increase in length as the center of the arc is approached. This is formed much like a part of a french curve drafting tool. 
         FIG. 11  shows in perspective a simplified form a cabinet that is a modified version of the cabinet of  FIGS. 1-4 , by making the back side of the cabinet curvilinear, providing a smoother appearance by eliminating the sharp corners where the cabinet sides are joined with the cabinet back side, and also capable of providing somewhat larger shelf areas. This cabinet has the back side curvingly formed as shown in  FIG. 6 , but it may instead be curvingly formed as shown by any of the  FIGS. 8-10 . It shows the foldable work surface, such as seen in  FIG. 5 , opened and in place to work on. 
         FIG. 12  is a frontal elevation view of the cabinet of  FIG. 11 , with the work surface in its stored position. 
         FIG. 13  a cross-section view of the cabinet as shown in  FIG. 12 , taken in the direction of arrows  13 - 13  of that figure, with the foldable work surface in the open position shown in  FIG. 11 . 
         FIG. 14  is a side elevation view of the cabinet of  FIGS. 11-13 , taken in the direction of arrows  14 - 14  of  FIG. 12 , with the foldable work surface in the open position shown in  FIG. 11 . 
         FIG. 15  is a rear view of the cabinet of  FIGS. 11-14 , taken in the direction of arrows  15 - 15  of  FIG. 14 . 
         FIG. 16  shows a mirror that is attached to the back side of the cabinet shown in  FIG. 15 , so that it may be used to be moved to a desirable angular position by moving the cabinet in the direction shown in the illustration seen in  FIG. 26 . 
         FIGS. 17 through 28  show, in much simplified form, the closed and open positions of a cabinet having various back side treatments, the cabinet being hinged to the door frame that also has the door hinged thereto using just one hinge part that is secured to the door frame to support both the cabinet and the door, and as shown in one instance, to also support a mirror. All of the views are in the direction as if the viewer is above the cabinet and is looking down on the cabinet installation in relation to the wall, door frame, and door on or relative to the structure on which the cabinet is pivotally supported. 
         FIG. 17  specifically shows the cabinet of  FIGS. 1-4  in its closed position relative to the door and the door frame. 
         FIG. 18  shows the cabinet of  FIG. 17  in an arcuate opening position, but not opened to its maximum extent relative to the door and the door frame. 
         FIG. 19  shows the cabinet of  FIG. 5 , which is the beveled back-side cabinet, in its closed position relative to the door and the door frame. 
         FIG. 20  shows the cabinet of  FIG. 19  in its maximum arcuate opening position relative to the door and the door frame. 
         FIG. 21  shows the cabinet of  FIG. 8  in its closed position relative to the door and the door frame. 
         FIG. 22  shows the cabinet of  FIG. 21  (and, except for the specific cabinet back side curvature, of the cabinet of  FIG. 9 ) in its maximum open position relative to the door and the door frame. This position is much like the maximum open position of the cabinet of  FIGS. 17 and 18 . 
         FIG. 23  shows the cabinet of  FIG. 10  in its closed position relative to the door and the door frame. 
         FIG. 24  shows the cabinet of  FIG. 23  in its maximum arcuate opening position relative to the door and the door frame. 
         FIG. 25  shows the cabinet of  FIG. 16  in its closed position relative to the door and the door frame. The mirror is available for viewing as needed. 
         FIG. 26  shows the cabinet of  FIG. 25  near its maximum arcuate opening position relative to the door and the door frame. The mirror is still available for viewing as needed, while the viewer is standing to the right of the cabinet. 
         FIG. 27  shows the cabinet of  FIGS. 5 and 19  as it is pivotally mounted relative to the door and the door frame, with a mirror like that seen in  FIG. 16  being separately mounted for pivotal movements relative to the door, its door frame. The mirror is positioned between the door and the cabinet with its mirror face being adjacent to the door surface  430 . The cabinet is shown in its closed position relative to the door and the door frame, and the mirror also being in its closed position to the door and the door frame. 
         FIG. 28  shows the cabinet of  FIG. 27  as it is pivotally mounted relative to the door and the door frame, with the mirror like that seen in  FIG. 16  being separately mounted for pivotal movements relative to the door, its door frame, and the cabinet. The cabinet is shown as having been arcuately moved near but not to its maximum arcuate opening position relative to the door and the door frame, and the mirror being arcuately moved to some extent relative to the door and the door frame, but not to its full extent. Such full extent could only be attained with the cabinet having also moved to its full extent. The mirror may be moved concurrently with the cabinet when the mover only wants to use the mirror or access the contents of the cabinet. Any of the alternatives mentioned above with regard to  FIG. 27  may be used as desired, so that the mirror is as visually accessible as the user desires it to be. 
         FIG. 29  is an elevation view of the upper one of the hinge parts that are secured to the cabinet of  FIGS. 1-4 , as well as other cabinets shown in  FIGS. 5 ,  11  through  16 , and the cabinets shown in  FIGS. 17-27 . It can also be used with the mirror of  FIGS. 27 and 28 . However, the hinges of  FIG. 31-33  or  37 - 38  may be used in some of the FIGURES to better advantage. The hinge of which this hinge part is a part is modified relative to the standard hinges used only to support a door for opening and closing pivotal movements. 
         FIG. 30  is an elevation view of the lower one of the hinge parts that are secured to the cabinet of  FIGS. 1-4 , as well as other cabinets shown in  FIGS. 5 ,  11  through  16 , and the cabinets shown in  FIGS. 17-27 . It can also be used with the mirror of  FIGS. 27 and 28 . However, the hinges of  FIG. 31-33  or  37 - 38  may be used in some of the FIGURES to better advantage. The hinge of which this hinge part is a part is modified relative to the standard hinges used only to support a door for opening and closing pivotal movements. 
         FIG. 31  is an end view of the hinge part of  FIG. 29 , taken in the direction of arrows  31 - 31  of that FIGURE. 
         FIG. 32  is an elevation view of a modified hinge part very similar to that of  FIG. 29 , but constructed to be used with the cabinet side when that cabinet side is connected to the cabinet back side as shown in  FIG. 6 , so that the extra bends in the hinge part receive a part of the cabinet side. 
         FIG. 33  is an end view of the hinge part  32 , clearly showing the extra bends in it to accommodate the construction of the cabinet side to which the hinge part is to be attached. 
         FIG. 34  is an elevation view of the modified hinge pin that is needed when a cabinet, or a mirror, or a cabinet and a mirror, are to be pivotally mounted to a hinge part that is secured to the door frame. 
         FIG. 35  is an end view of the pin of  FIG. 34 , taken in the direction of arrows  35 - 35  of that figure. 
         FIG. 36  is a perspective view of the modified hinge pin shown in  FIG. 34 . 
         FIG. 37  is a plan view of a further modified hinge showing parts that are secured to a cabinet or a mirror to cooperate with hinge parts secured to a door frame for pivotally mounting the cabinet or the mirror on the same hinge parts secured to the door frame that also pivotally support the door and one, or two, of other devices such as a cabinet and a mirror, on the door frame. 
         FIG. 38  is an end view of the hinge parts  37 , taken in the direction of arrows  38 - 38  of that FIGURE. 
         FIGS. 39   a  and  39   b  shows preferred way to attach the curvilinear back to the cabinet sides, and to attach a hinge part to the cabinet that will receive a hinge pin in a cylindridal section of that hinge part. The wood parts of the cabinet are shown in section. The view in  FIG. 39   a  is a cross-section view taken in the direction of arrows  39   a - 39   a  of  FIG. 11 .  FIG. 39   b  is a cross-section view taken in the direction of arrows  39   b - 39   b  of  FIG. 12 .

     DETAILED DESCRIPTION OF THE INVENTION 
     The cabinet  20  shown in  FIGS. 1-4  has a bottom  22 , a top  24 , a first side  26 , a second side  28 , and a third side  30 , which is the back of the cabinet. It has a series of shelves  32 ,  34 ,  36 ,  36 ,  38 ,  40 ,  42  and  44  that are adjustably mounted to the inner surface  46  of side  26  and the inner surface  48  of side  28 . It is often advantageous to make one or more of the shelves be fixed. Shelf  38  is the fixed shelf in this cabinet  20 . Any of several available adjustment arrangements may be used if the shelves are not to be permanently fastened to the cabinet sides. These shelves extend from the back side  30  forward to or at least very near to the cabinet front surfaces that are defined by the front edges  52  of the bottom  22 ,  54  of the top  24 , and  56  and  58 , respectively, of the two sides  26  and  28 . 
     One of the sides, depending on the side of the door to which the cabinet is located when installed, so in this showing that side is side  28 . It has at least two vertical slots, and preferably three to five such slots  60 ,  61 ,  62 ,  63 , and  64 . These slots are better shown in  FIGS. 1 and 3 , with the side  28  having these slots therein. It would be side  26  if the hinges are to be near that other side. Slots  60 ,  62  and  64  are located slightly inward of the front surface  58  of the side  28 . There is a loop and hook fastener  68 , made of Velcro™ or the like, with one half of it being mounted on the door at a designated spot, and the other half being mounted on the cabinet at a designated spot so that, when the cabinet is closed against the door, the two parts of the fastener  68  engage, and hold the cabinet in its closed position against the door until such time as the cabinet is forced, against the gripping action of the fastener, to disengage the two parts of the fastener  68 .  FIG. 3  also illustrates the adjustable ability of fastening those hinge parts to the cabinet to readily fit with the proper height of the door hinges, and also the fore-to-aft adjustment arrangement relative to the availability of the pins of the door hinges. 
       FIG. 5  shows a door  400  mounted in a door frame  402  by its hinges  406 . A cabinet  408  embodying a part of the invention is pivotally mounted on the door hinges  404  and  406  using hinges  70  and  72  of  FIGS. 29-31 , or the hinges  200  of  FIGS. 37 and 38 .  FIG. 5  is a perspective view of a typical door  400  that provides access between two rooms, the door being mounted on hinge parts  404  and  406  of hinges  70  and  72 , which are shown in  FIGS. 29-31 . These hinges have parts that are pivotally secured together so that they pivotally attach the door  400  to its door frame  402 . The hinges pivotally supporting the door  400  on the door frame  402  may be located at an upper part, a middle part, and a lower part on the door and also secured to the door frame at corresponding points. However, for the purpose of mounting the cabinet  408 , or any other cabinet, on the door frame and also on the door via parts of its hinges, only a minimum of two of the hinges are shown in  FIGS. 1-4  which are employed to also pivotally mount the cabinet to the door  400  and to the door frame  402  so that it may be pivotally moved in the arc  408 ′ relative to the door and/or relative to the door frame. Cabinet  408  is a modification of the cabinet of  FIGS. 1-4  also embodying the invention, and is shown opened relative to the door  400  and to the door frame  402 . 
     The vertical opposite sides  410  and  412  of the modified cabinet are shown as being beveled inwardly, with the respective front edges  430  and  432  of those sides extending further from the cabinet back side than their back edges, rendering the back edges of the two cabinet vertical sides to be closer to each other than are the front edges  430  and  432  of those cabinet vertical sides  410  and  412 , allowing the bevel-sided cabinet to be opened so that the arc  408 ′ is capable of being becomes substantially greater than 90° before the cabinet back edge of vertical side  410  touches the surface  434  of the door frame  402 . Cabinet  408  has sides  410  and  412 , a back side  414 , a top  416  and a bottom  418 . Top  416  and bottom  418  are also beveled in order to meet the beveling of the sides  410  and  412  at the top and bottom parts of the cabinet. Also, the ends of the cabinets bottom  418  and top  416  are formed so that they are slightly trapezoidal in shape, rather than rectangular, as shown in  FIGS. 1-4 . This allows the sides  410  and  412  to be positioned so that their edges connected to the cabinet back  414  are slightly tapered from the front toward the back of the cabinet. This also permits the cabinet to be moved arcuately outwardly well over 90° as shown by arc  408 ′ without requiring the double-hinged hinges shown in  FIGS. 12 and 13 , and described below. These beveled vertical sides have a less-than-90° relationship to the cabinet back side, on the order of one or two degrees, up to as much as 10° or more, depending on the amount of additional opening beyond about 90° that is desired. Usually, an opening of through the arc  408 ′ of about 120° to 135° is sufficient. 
     There are some shelves  420  that extend from side  410  to side  412  and back  414 . There are other shelves  422  that are of lesser length that shelves  420 , and therefore only are attached to side  412  and back  414 , leaving a space from the upper shelf  420  to the top  416  open so that taller items may be stored there. Shelves may be provided at any desired vertical spacing, and may extend only from one of the sides  410  and  412  as desired. 
     Some of this cabinet&#39;s versatility is shown. The board  404  may be pivoted downwardly from its stored position, and it has a leg  426  which can be held in a downward position to support the free end  428  of board  404 . This board may be used for many different tasks. For example, it may be a general workplace or a desk space. It may also be used as an ironing board, a drafting table, a surface for assembling relatively small items, a space for wrapping packages or boxes, sewing with a portable sewing machine, and many other similar tasks. It is folded out to work on its surface, and is preferably level in relation to the room floor. When not in use, it may be folded upward about 90° so that it covers a part of the cabinet storage area. Just below the lower shelf  420 , the board  404  is pivotally attached to the sides  410  and  412  so that it may be pivoted upward into its stored position, the front-to-back widths of shelves  420  and  422  being slightly less than the depth of the cabinet from the front edges of the sides  410  and  412 , allowing sufficient space for the board  404  to be stored within the sides  408  and  410 . There may be a latch, not shown, securing the board in its stored position. Or, the two parts of a hook and loop fastener may be respectively attached to the bottom of board  404  and to the inner side of the leg  426 , so that when the board is folded up, the leg remains in contact with the board. 
       FIGS. 6-10  show some details of the provision of a curvilinear back side to a cabinet  140  described below in relation to  FIGS. 11-15 , as well as the descriptions of  FIGS. 19 through 28 . 
       FIG. 6  shows the two cabinet sides  142  and  144 , a shelf  146 , and a curvilinear back side  148 . The shelf has a planar front surface  150 , and a curved back surface  152 . The cabinet sides have one of the sides (or both if the cabinet is being made to be connected to hinges to either of the sides, in the manner shown in  FIG. 3 , for example) provided with slots such as slots  60 ,  62 , and  64  of  FIGS. 1-4 , for attachment of parts of at least two hinge sets to the cabinet. One of the slots,  60 , for example, is seen in the cabinet side  144 . If it is likely that a cabinet may at some point be hinged with the side  142  having hinges attached thereto, the slots  60 ,  62  and  64  may also be provided in that side. 
     In  FIG. 7 , which is a side view of side  144 , two of such slots are shown. At times, there may be four or five or more of such slots per side, depending upon the height of the cabinet and the number of hinges to be used. 
     In  FIG. 6 , Each of the two cabinet sides  142  and  144  has a back side mounting bar  154  having one of the two angularly disposed slots  156 ,  158  that extend into the back side surface of the side  144  so that their open ends  160 ,  162  are at a precise angle to the vertical larger surfaces forming the inner and outer sides of the cabinet sides  142  and  144 . This angle is determined by the angle that the outer side edges of the curvilinear back surface has to have to be inserted into those angularly disposed slots when the curvilinear back side  148  is assembled with the cabinet sides  142  and  144 . Those angles of extension depend upon the final desired cross-section shape of the curvilinear back side  148 , the flexibility of the material of which that back side is made, and the desired depths of the shelves at their deepest point and at their shallow ends. The curvilinear shape of the installed curvilinear side  148  is finally determined as it is attached permanently to the cabinet sides  144  and  146  via the mounting bars  154  and the shelf curvilinear back side  148 . This attachment is accomplished by the application of Carpenter&#39;s Glue or its equivalent, and decorative screws  172  that are screwed through the curvilinear shelf back side  148  and into the shelf  146  and the other similar shelves as well as into the top and the bottom of each cabinet. 
     Shelf  146  has the surface of its edge  164  formed as an arc  174  of a circle that has a radius  166  originating at the circle&#39;s center  168 . As shown in this instance, the radius  166  of that circle is somewhat longer in length than the length of the chord defined by the shelf front surface  150 ; the radius determining the amount of curvature by which the shelf has been curved on its surface  164  in order to give a desirable amount of maximum depth to each shelf at the center of it from each cabinet side, and the depth that decreases with the length of the shelf front surface  150  that is away from the centerline arc  166  until there is no more shelf surface at either end of each shelf. The screws  172  and the mounting bars  154  will hold the cabinet sides  144  and  146  and the back side  148  in position as the adhesive sets. The screws and the adhesive assure the solid structure of the cabinet. 
     The flexible curvilinear back side need not be curved with a single constant radius. It may be curved with two different radii lengths as shown in  FIGS. 8 and 9 , and with continually changing radii as shown in  FIG. 10 . These complete arcs are shown schematically in each of  FIGS. 6 ,  8  and  10  as being connected to the schematically simplified cabinet sides  142  and  144  with the slots receiving the edges of the back side being substantially parallel. That not need be the case, but for some of the curvilinear shapes that is quite feasible. The preferred material is a relatively thin plywood material with a fine finish on at least the outer side thereof, it is to be understood that the curvilinear cabinet back sides can be made of in casting forms using a hard plastic, or fine wood chips mush like particle board, and usually having a fine outer finish. Wood is the preferred material to make the cabinets, but the entire cabinet, or just portions of it, can be made of hard plastic materials. 
     As shown in  FIG. 8 , the back side  174  may be curved using three different radii lengths, two such redii  180  and  182  being the shorter radii and one such radius  184  being the much longer radius extending from its circular center  185 . Two very short radii  180 ′ and  182 ′ are located only at and near the ends of the curvilinear back side  174  and originate at the centers  186  of their respective circles of which their arc parts  188  and  190  are parts. These two arc parts are located at opposite ends of the total arc  194  forming the complete back side&#39;s curvilinear shape. Arc part  192 , defined by the radius  184  extending from its center  187 , and also by the radii  182 , takes up about 84% to 94% of the total of the five arcs portions forming the complete back side&#39;s curvilinear shape. That complete back side curvilinear shape has the art parts  188  and  190  at the opposite ends of the arc part  192 . The two arc parts  188  and  190  each makes up about 2% to 8% of that back side curvilinear shape total arc  194  in this arrangement. The different curvitures of arc are merged over a short distance where they meet to provide a smooth change from the curvature arc part  192  to the curvature arc parts  188  and  190  respectively defined by the two shortest radii  180 ′ and 182′. 
     In  FIG. 9 , the arrangement is similar to that in  FIG. 8 . There are two radii  181  and  183  which are relatively short in relation to the considerably longer radius  98 , yet considerably longer than the short radii  180 ′ and  182 ′ of  FIG. 8 . Each shorter radius  181  and  183  subtends one of the arc parts  196  and  197 . The longer radius  198  subtends an arc part  199 . In this arrangement each arc part  196  and  197  is about 25% of the total arc  195 , and the arc part  199  is about 50% of the total arc  195 . It is to be clear to understand that there may be other arc parts covering different percentages of the total arc to obtain the desired shelf shape for storage and therefore the desired cabinet back side curvilinear shape. 
     As it is shown in  FIG. 10 , the total curvilinear arc  208  of a cabinet curvilinear back side can be made with the arc curves resulting from progressive radius lengths, much like the edge of a French Curve drawing tool. This is also schematically shown in  FIGS. 21-22 . In  FIG. 10 , the radii change from shorter radii to longer radii as the total arc  208  proceeds from one end of the shelf  146  to the center of the minimum arc curvature, and then proceeds from longer radii to shorter radii as the total arc proceeds from the center of the minimum arc curvature to the other end of that shelf. Therefore, the lengths of the illustrated radii  210 ,  212  and  214 , then radii  216  and  218 , are only instantaneous specific lengths, resulting in the curvature of the total curvilinear arc  208  continuously changing and therefore the area and shape of the area of each shelf changes in concert with those arc changes, still usually resulting in a greater working area of each shelf as compared to the shelves of  FIGS. 1-4 , for example. Of course, it the progressive changes of radii should be used with a shelf similar to the shelf in  FIG. 8 , like the shelf of  FIG. 8 , the shelf storage area may be less that the storage area of a shelf in  FIGS. 11 through 15 . 
       FIG. 11  shows in a simplified perspective a modified form of the cabinet shown in  FIGS. 1-4 . Cabinet  300  has a first side  302 , a second side  304 , a curved back  306 , a top  310 , a bottom  312 , and shelves  314 . These shelves have arcuate back edges to which the curvilinear back  306  is attached. That back is also attached at its side edges to the sides  302  and  304 . Cabinet  300  also has a workplace board  316  which is pivotable from it storage position shown in  FIG. 12  and supported by its foldable leg  318 . The curvilinear back side  306  is preferably made from a flat panel that is sufficiently flexible to be bent arcuately as shown. There are plywood parts available having a small thickness which can easily so curved or bent. One example is a thin plywood cover for cabinets that are being refaced. It may also be made of a flexible plastic, or be premolded to shape, and the shelves  314  may optionally be integrated with that promolded back. In  FIG. 11 , the cabinet is shown as having hinge parts  240  or  340  and  322  on its side  304 . The cabinet would then be pivoted outward in a clockwise direction from the door with which is also pivotally attached to a door frame. It would be mounted on the door hinges connected to the door frame, with the door hinges also being on the left side as viewed by an observer. The hinge parts  240  or  320  and  322  may alternatively be on the side  302  instead, and then the cabinet, and the door with which it is pivoted, would open in a counterclockwise arc. This arrangement is shown in  FIGS. 12 ,  15 , and in all of the  FIGS. 17 through 28 . 
       FIG. 12  is a front elevation view of the cabinet  300  of  FIG. 11 , showing the workplace  316  folded up against some of the cabinet shelf front edges. In doing so, it helps retain any items stored on those particular shelves. If the leg  318  is pivotally attached to the bottom instead of the underside of the workplace panel, the lower shelves may be notched, as shown in  FIG. 6 , to receive the leg. In that instance, the workpiece  316  would also have its pivoting inner end  324  equipped with a sliding pivot so that the workpiece would be stored with its pivoting inner end being uppermost. 
       FIG. 13  shows the cabinet  300  of  FIGS. 11 and 12 , in cross section, taken in the direction of arrows  13 - 13  of  FIG. 11 . Its workplace  316  is folded down from its storage position, shown in  FIG. 12 , and the workplace leg  318  supports the workplace so that it may be in use for various tasks. Cabinet  300  has several shelves  314 , with the lower ones being more closely spaced vertically than are the two upper ones  314  and  316  of those shelves. In this FIGURE, and  FIGS. 12 and 13 , the hinges  320  and  322  are on the left side (as seen by the viewer) of the cabinet. As noted above, the cabinet would be opened from the door by pivotal movements in a counterclockwise direction. The door would be opened in that same arcuate direction. 
       FIG. 14  is a side elevation view of the cabinet  300  of  FIGS. 11 ,  12  and  13 , taken in the direction of arrows  14 - 14  of  FIG. 11 , with the workplace  316  being folded down from its storage position, and the workplace leg  318  supporting the workplace so that it may be in use for various tasks. In this view, one can see the right side  304  and the curvilinear back side  306 , as well as the edges of the top  310  and the bottom  312 . Since the hinges  320  and  322  are attached to the side  304  of the cabinet, they are visible in this view. 
       FIG. 15  is an elevation view of the curved back side  302  of a cabinet  300 , showing the hinges  304  and  306  that have it fitted as the hinges of a door such as door  400  of  FIG. 5 . 
       FIG. 16  is an elevation view of a mirror  330  that is either mounted on the back side  30  of the cabinet  20 , shown in any of the  FIGS. 1-4 , or  FIGS. 11-15  if any of those cabinets are modified to have a flat back side like those in  FIGS. 1-4 , so that the mirror  330  is shown as being attached to the back side of the cabinet, so that it may be readily be used at any time that the cabinet is closed or only slightly open. In this arrangement, because the mirror  330  really is a part of the cabinet, it does not need to have separate hinges. 
     There are alternatives on how to use the mirror  330 , as mentioned below in the detailed description of  FIGS. 27 and 28 . In each of those alternatives, the mirror  330  may be a pivotal element in its own right, and may be mounted with hinges on the hinge parts secured to the door frame  402 . The alternative actually used can be left to the ultimate customer. When the mirror  330  is so independently pivoted, the hinges  320  and  322  would be on the right side (as seen by the viewer) if the door also has its hinges on its right side as seen in  FIG. 4 . With this arrangement, it could be visible without having to pivot the cabinet, and would be located in front of the cabinet with the cabinet and the mirror being pivotally closed. 
     Alternatively, mirror  330  could be pivotally mounted inbetween the cabinet and the door surface  430 , with its mirrored surface  332  facing the cabinet, and could be seen, and used as a mirror, if the cabinet is pivoted outwardly. In that mounting, if the mirror surface  332  faces the cabinet, then it would be fully accessible only if the cabinet is more fully opened. Of course, in this arrangement it would be mounted with its hinges on its left side as seen in this  FIG. 16 , and be so mounted relative to the door that the mirror surface  332  would be closed against the door surface  430 , and the cabinet would be outside of the mirror  330 , as seen in  FIGS. 27 and 28 . 
       FIGS. 17 through 28  show, in much simplified and diagrammatic form, the closed and open positions of a cabinet having various back side treatments, and some manners of mounting a dress mirror, or a smaller one if desired, so that it can pivot either independently with or as a part of a cabinet relative to the door, All of the views are in the direction as if the viewer is above the cabinet and is looking down on the cabinet installation in relation to the wall, door frame, and door on or relative to the structure on which the cabinet is pivotally supported. Any statements about left and right sides shall be taken that such views are as they would be seen by an observer looking down on that particular arrangement and standing in front of, or above, the device or devices that are in front of the door front surface  430 . Because there are not necessarily cabinets directly disclosed that can be tied to the various shelf and back sides and left and right sides that use the particular shelf shown, there will be given reference numbers to each set of FIGURES which are to represent a cabinet having that particular shelf and back side shown. When those numbered cabinets also can sometimes be tied to a specific cabinet in other FIGURES, that cabinet will be mentioned. The cabinet curvilinear back sides may be made using radii that are considerably shorter than the width of the cabinet to using radii that are as much as about twenty times the width of the cabinet. The radii may be used to define the curvature of the curvilinear back side may be in only one size, or two sizes, or three or more sizes, or be continually changing redii so that the parts of the curvilinear back side subtended by each radius continually changes their amounts of curvature. Examples of the usage of some of these different radii sizes are shown in some of the drawing figures and described as needed. 
       FIG. 17  specifically shows the cabinet  250  in its closed position relative to the door  400  and the door frame  402 . Cabinet  250  is equivalent to cabinet  20  of  FIGS. 1-4 . 
       FIG. 18  shows the cabinet  250  having been moved along arc  252  in an arcuately opened position, but not opened to its maximum extent relative to the door  400  and the door frame  402 . 
       FIG. 19  shows the cabinet  254 , which is a beveled back-side cabinet such as cabinet  400  of  FIG. 5 , in its closed position relative to the door  400  and the door frame  402 . 
       FIG. 20  shows the cabinet  254  having been moved along arc  256  to its maximum arcuately open position relative to the door  400  and the door frame  402 . 
       FIG. 21  shows a cabinet  258  in its closed position relative to the door  400  and the door frame  402 . Cabinet  258  is comparable to cabinet  300  of  FIGS. 11-15  and therefore may be such a cabinet. 
       FIG. 22  shows the cabinet  258  having been moved along arc  260  to its maximum open position relative to the door  400  and the door frame  402 . This position is much like the maximum open position of the cabinet  250 , of  FIGS. 17 and 18 , which is shown in  FIG. 18  in its maximum open position. 
       FIG. 23  shows the cabinet  262  in its closed position relative to the door  400  and the door frame  402 . Cabinet  262  is similar to a cabinet having the features of  FIG. 9 . 
       FIG. 24  shows the cabinet  262  having been moved along arc  264  to a location that is short of its maximum arcuate opening position relative to the door  400  and the door frame  402 . Cabinet  262  can be moved further along arc  264  until it reaches its maximum arcuate opening position. Cabinet  262  is similar to a cabinet having the features of  FIG. 10 . 
       FIG. 25  shows the cabinet  266  having a mirror  330  secured to its back side, and which may actually be its back side, the cabinet with its fixed mirror being in its closed position relative to the door  400  and the door frame  402 . The mirror  330  is available for use as needed in this closed position. It has its mirror face  332  facing away from the cabinet  266 . 
       FIG. 26  shows the cabinet  266  having been moved along arc  268  to the extent that it is near, but not yet at, its maximum arcuate opening position relative to the door and the door frame  402 . The mirror  330  is still available for viewing as needed, provided the viewer is standing to the right of the cabinet after the cabinet  266  and mirror  330  have been moved to the position shown. 
       FIG. 27  shows the cabinet  270  of  FIGS. 5 and 19  as it is pivotally mounted relative to the door and the door frame, with a mirror  330 , like that seen in  FIG. 16 , being separately mounted for pivotal movements relative to the door  400  its door frame  402 . The mirror  330  is positioned between the door  400  and the cabinet  270 , with its mirror face  232  being adjacent to the door surface  430 , and it is independently hinged to the door frame  402  just as and to the extent that door  400  and the cabinet  270  are. The cabinet  270  is shown in its closed position relative to the door  400  and the door frame  402 , and the mirror  330  also being in its closed position relative to the door  400  and the door frame  402 . Cabinet  270  is very similar to the cabinet  408  of  FIG. 5  and the cabinet  254  shown in  FIG. 19 , in that it has beveled sides and top as those cabinets do, and it can, like them, move arcuately through an arc of about 120° to 135° from the position of the door  400  when that door is closed, before it reaches its maximum movement along that arc. That arc is arc  272 , shown in  FIG. 28 . 
       FIG. 28  shows the cabinet  270  as it has been pivotally moved arcuately along arc  272  relative to the door  400 , the door frame  402 , and the mirror  330 , with the mirror  330  having been separately moved arcuately along arc  272  to a lesser extent relative to the door  400 , the door frame  402 , and the cabinet  270 . That extent is shown as being about half as arcuately far as the cabinet  270  was moved relative to the door  400  and its door frame  402 . The cabinet is shown as having been arcuately moved about 90° which is near but not to its maximum arcuate opening position relative to the door and the door frame, either, and so the mirror  330  has been arcuately moved about 40° to 45° relative to the door  400  and the door frame  402 , but not to its full extent, which may be about 90° to about 120° along the arc  272 . Such full extent could only be attained with the cabinet  270  having also moved to or at least very near its full extent. The mirror  330  may be moved concurrently with the cabinet  330  when the mover only wants to use the mirror or access the contents of the cabinet. Any of the alternatives mentioned above with regard to  FIG. 27  may be used as desired, so that the mirror is as visually accessible as the user desires it to be. 
     Referring now to  FIGS. 29-33 , these FIGURES show the hinge parts  70  and  72 . Part  70  has its main body  74  having slots  76  and  78 , and part  72  has its main body  80  having slots  82  and  84 . As shown, each of these slots, as viewed in  FIGS. 29 and 30 , has a respective longitudinal axis  86 ,  88 ,  90 , and  92  that lie in parallel planes illustrated by those axes. Also, their upper and lower ends have end points  100  and  102  for slot  76 ,  104  and  106  for slot  78 ,  108  and  110  for slot  82 , and  112  and  114  for slot  84 . The upper end points  100  and  104 , and the lower end points  102  and  106 , of slots  76  and  78 , lie in parallel vertical planes indicated by dashed lines  116  and  118 . Similarly, the upper end points  108  and  112  and the lower end points  110  and  114 , respectively of slots  82  and  84 , also lie in parallel vertical planes  120  and  122 . This arrangement makes it possible, together with the slots  60 ,  62  and  64 , to adjust the cabinet hinge parts to properly mate with the hinge parts of the door hinges. Each of the hinge parts  70  and  72  respectively has a cylindrical opening part  123  and  124 , formed out of those hinge parts. 
     As shown in  FIG. 31 , the cylindrical opening part  124  has been made by striking out an extended portion of the hinge part  72 , so that it first extends at an angle of about 50° from the plane of the hinge part  72 , and is then curved to form the cylindrical-opening part  124 . The cylindrical opening parts  123  and  124  are similarly and respectively formed from the hinge part  70  and hinge part  72 . The cylindrical opening parts  123  and  124  respectively have openings  125  and  126  which respectively have axes  127  and  128 . Hinge parts  70  and  72  are to be fastened to the cabinet. There are other hinge parts, described in more detail below, that are fastened to the door frame  402  to support the cabinet&#39;s hinge parts  70  and  72 , and the door-mounted hinge parts schematically shown in  FIGS. 17 through 28 , to support the door via its hinge parts, and to support the cabinet by its hinge parts  70  and  72 . The openings  125  and  126  are axially aligned with similar openings in the hinge parts that support the door on the door frame  402  so that the hinge pins such as that shown in  FIGS. 34 through 36  can be inserted. In making this connection all of the cylindrical opening parts of the various hinge parts have the hinge pins extending therethrough in axial alignment. When a door and a cabinet are so mounted, there are at least a first two hinge parts mounted on the door frame, a second at least two of the hinge parts mounted on the door, and a third at least two hinge parts mounted on the cabinet, with the cylindrical opening parts in axial alignment with the hinge parts on the door. This is accomplished by axially staggering the cylindrical opening parts so that one hinge pin can be, and is, inserted in each set of hinges, so that the door and the cabinet are separately, within arcuate limits, mounted on the door frame so that the door and the cabinet may be arcuately moved as a unit as when opening the door to pass through the door opening. When it is desired to open the cabinet but leave the door closed, the cabinet is pulled arcuately about the hinge pins away from the door, the loop and hook fastener  68  being pulled apart. The cabinet can be pivotally so opened as needed, to a maximum arc of about 90° to as much as about 150° or so, depending in part on the particular type of hinges used, and the shape of the exterior sides of the cabinet, as further described above and shown in  FIGS. 17-28 . 
       FIG. 32  is a plan view of the ½ of one of the hinges  404 ,  406  that may be used with the cabinet  408  of  FIG. 5 , as well as other cabinets having the construction shown in  FIG. 6  in which the mounting bars  154  are so made that, in their securement to the cabinet side  144 , they extend laterally outward of the plane of the outer surface of the side  144 . The half  70  shown in this figure has a flat surface  74  which has slotted openings  76  and  78  through which the bolts  186  shown in  FIG. 33  extend. The bolts extend into the stepped area  188  formed on the inner side  190  of the side  144 , shown in  FIG. 6  in cross section and in  FIG. 7 . As seen in  FIGS. 6 and 7 , there is a nut  194  located so that one flat side of it engages the step  196  forming the stepped area and the opposite flat side of that nut engages the mounting bar. These engagements prevent the nut from turning with the bolt  186  when that bolt is tightly threaded into the nut to hold the hinge half  70  firmly on the cabinet. Because the slotted openings  76  and  78  have their linear axes slanted about 70° from the horizontal edge of the hinge parts  70 , the hinges can be vertically and horizontally adjusted until the hinge parts are properly positioned. This is the manner in which various hinge parts are connected and attached to the cabinets, the doors, and the mirrors that are shown in various FIGURES, and are in the final installations are pivotally supported by hinge parts that are pivotally attached to other hinge parts secured to the door frame. This described procedure is used with the various hinge parts disclosed herein. 
     The change in the hinge part  70  of  FIG. 32 , shown better in  FIG. 33 , that is important is that the main body  74  of the hinge part has two substantially oppositely bent right-angled bends  127 ′ and  128 ′ in it to move the part of that main body  74  from which the circular section  124 ′ is struck to allow that main body part and the circular section  124 ′ to be located over the outer part of the mounting bar  134  as shown in  FIG. 6 . This is needed when the construction of the cabinets is as shown in  FIG. 6 . In some other cabinet constructions, such as those in  FIGS. 1-4 , there is no need for this double bend arrangement because there are no protuberances such as the mounting bars  154  that may interfere with the location of the hinge part. 
       FIGS. 34 ,  35  and  36  show the modified hinge pin  130  in a side elevation view, the modified hinge pin being substituted for the standard hinge pin, which has a head on its upper end much like the head of a typical nail, when any of the hinge arrangements that are shown herein are used. This modified hinge pin  130  has an extension  132  added onto a standard hinge pin that coaxially receives a cylindrical-opening part of the hinge body when the hinge is positioned on the modified pin, and the bottom edge of that cylindrical-opening part rests on that pin head  134  from which that extension  132  extends. If the modified pin has been installed with the hinge pin enlarged section  134  and the extended portion  132  of the pin beyond it is on the bottom of the hinge set, the hinge pin enlarged portion  134  takes no vertical load factor of the cabinet. Even so, the portion of that hinge pin below that enlarged section does guide and locate the entire hinge set, and thus the cabinet, in their desired aligned positions when the cabinet is pivoted away from the door side surface facing the cabinet when the cabinet is closed by that door side surface. 
     Hinge  200  of  FIGS. 37 and 38  is a double hinge. It has one section  202  that is secured to the cabinet in a manner similar to the hinge parts  70  of  FIG. 29 , or  32 . The hinge section  202  is also engaged with the modified hinge pin  130  of  FIGS. 34-36 , another section  204  that is similar to hinge section  70  or  72  of  FIG. 29 , and in that it has slots  276  and  278  that are similar to slots  76  and  78  of  FIG. 29 . Sections  202  and  204  are hinged together about a pin  206 . Pin  206  is received by cylindrical openings  220  and  222  formed from the sections  202  and  204 . The section  202  is connected by the pin that is also received in the hinge part that is attached to the door frame. By use of this type of hinge, the cabinet can be opened for a greater arc of movement, even when it is not tapered as above described. 
       FIGS. 39   a  and  39   b  are closely related to the respective right and left portions of the view shown in  FIG. 6 . They show the preferred manner of attaching a flexible cabinet back side to the sides of the cabinet shown in  FIGS. 11 through 15 . They also show a hinge part  240 . The cabinets  224  of  FIGS. 11 and 226  of  FIG. 12  each has sides  226  and  228 . Side  226  is shown in  FIG. 39   a  and side  228  is shown  FIG. 39   b . These sides are very similar to the sides  142  and  144  of  FIG. 6 , but instead of their width being fore and aft on the cabinet their width extends laterally of the cabinet as shown in  FIGS. 11 and 12 . Therefore, the slots  62  of the sides  142   144 , shown in  FIG. 7 , are seen as they are shown in  FIG. 7 , opening outwardly, as do the slots seen in the views of the fronts of the cabinets  224  and  226 . The mounting bars  228  and  230 , which are similar to the mounting bars  154  of  FIG. 6 , also have their width extending laterally of the cabinet. Both the cabinet sides  224  and  226 , and the mounting bars  228  and  230  extend vertically for the height of the cabinet, less the thicknesses of the respective cabinet tops and bottoms. The angled slots  156  and  158  in the mounting bar  154  are replicated as slots  232  and  234  in  FIGS. 39   a  and  39   b , and are shown receiving one side edges of the curvilinear side, or the other side edge. The unnumbered slots of  FIG. 6 , shown in the mounting bars  154  as receiving edges of the cabinet sides  142  and  144 , are respectively shown as slots  232  and  234  in both of the  FIGS. 39   a  and  39   b . In these two figures, they each respectively receive nuts  236  and  238  when there is to be a hinge section  240  installed on the left side, or the right side, of a cabinet. These hinge sections are shown in  FIG. 11  as being on the right side of the cabinet, and in  FIG. 12  are shown as being on the left side of the cabinet. As earlier noted, the hinge sections secured to the cabinets are located on one side or the other, depending on the way the cabinet is being supported by the hinge sections and hinge pins when installed. In  FIG. 5  as well as in the  FIGS. 17 through 28 , the cabinet hinge pins are on the left side of the cabinets, as they are seen in  FIG. 12 . 
     The hinge section  240  shown in  FIGS. 40 and 41  has a main body section  242 , which has openings  244  in it through which the bolts  246  extend, and hold the hinge section securely to the cabinet. It has an extension on the end of which is the formed cylindrical opening  248  for receiving a hinge pin therethrough. It is the main body section  242  of the hinge section  240  that is received in the recess formed in the cabinet sides  142  and  144 , with a set of bolts  60 , here shown as probably being four bolts, because there are four bolt holes  244  in that hinge section, which extend through each of those bolt holes  50  in the cabinet side to which the hinge sections are to be attached, then through each of the bolt holes  244 , and then threaded into the nuts  236  in  FIG. 39   a , and  238  in  FIG. 39   b , and tightened to secure the hinge section in place to the cabinet. The size of the slots  232  and  234  are such that the square or hex-sided nuts cannot be turned as the bolts are turned and screwed tightly in those nuts. 
       FIG. 42  is a perspective view of a door, door frame and hinge set. 
     Because some confusion may exist concerning the hinges and their hinge parts, in relation to their connection to the door, the door frame, the several cabinets and the mirror, the following terminology has been developed. 
     There are three types of hinge sets, identified as A, B, and C. There are three parts in each of these hinge sets. They are two hinge sections and a hinge pin. One of these two sections is secured to the door frame, and the other is secured to the door or to the cabinet being hung on the hinges that support the door. 
     When the door  400  has been previously installed on the door frame  402 , it has two or more hinge sets A installed. The hinge parts of each of the hinge sets A that are secured to the door  400  are hinge parts W, and the hinge parts that are secured to the door frame  402  is hinge part X. Hinge parts W and X are connected by the hinge pin P. 
     In the following identifications, “hp” means “hinge part” and the letter following it identifies a particular hinge part. “P” is the standard hinge pin that would be in the standard hinge set A when there was no cabinet supported by those hinges. “P 1 ” is a longer hinge pin that is used when the hinges are modified to support a cabinet as well as the door. The definitions of the various hinge sets as they are connected to the door and the door frame, or to the cabinet and the door and also on the door frame are set forth below. 
     There are at least two of each of the originally installed hinge sets, here defined as:
 
hinge set A=Door-hpW-P-hpX-Door Frame
 
     The at least two hinge sets A are the two or more hinge sets already supporting the door  400  on the door frame  402 . They are the ones that were installed when the only item that was contemplated to be supported by hinges was the door. Therefore, the hinge sets A still have the two hinge parts W and X. If the door  400  and the cabinet are being installed together for the first time, the installer would start out with hinge set C. However, if he approaches the installation when the door is supported by the hinge sets A, he will usually begin by substituting the hinge pins P 1  for the original hinge pins P. This action will result in the hinge set B being created. It is only done for temporary purposes. The installer may just skip creation of hinge sets B, and go directly to hinge sets C, defined below. 
     In order to begin the installation of a cabinet that is to be supported on the same hinges as the door  400 , hinge sets A have to be modified. First there has to be a longer length hinge pin. Therefore, P 1  must be substituted for the original hinge P. This provides the following hinge set B, of which there are at least two:
 
hinge set B=Door-hpW-P 1 -hpX-Door Frame.
 
     The hinge sets that are to support the cabinet on the door frame  402 , may be at least two hinge sets. When there are three hinge sets A or B supporting the door  400  on the door frame  402 , the cabinet may need only two of the hinge sets B when the cabinet does not extend its vertical height so that it covers three hinge sets for the door  400 , or it may be of sufficient height to also require three such hinge sets when there are three hinge sets supporting the door  400  on the door frame  402 . 
     When the installer begins the actual installation of the cabinet, he must change the former hinge sets, whether they be hinge sets A or B, to hinge sets C. Each hinge set C is assembled as follows, using hinge part Y for the beginning part of the hinge set C that is to support, and the hinge part Z, which is substituted for the hinge part W. Hinge set C is assembled as follows:
         hinge set C=cabinet-hpY-P 1  and door-hpZ-P 1  and those two hinge parts being connected by P 1  to the hpX that is still mounted on the door frame  402 .       

     The different hinge parts Y, Z, and P 1  are required in order to allow the cabinet to be supported on the same hinge parts secured to the door frame  402  as is the door  400  relative to the door frame  402 , and particularly to permit them to swing sufficiently far away from the door to allow the interior of the cabinet to be accessed when desired. 
     The above presentation parts have the following relation to the numbered parts in the drawings: 
     As illustrated in  FIG. 42 , Hinge set A=Hinge set  344  Door= 340 ,  400  Door Frame= 402 .
         hpW (hinge part W)= 348 , P=the standard hinge pin  356     P 1 =the elongated hinge pin  130     hpY=hinge part attached to the cabinet and pivotally mounted on P   hpZ=hinge part attached to the door and pivotally mounted on P   hpX=hinge part attached by one end of it to the door frame and having P 1  received on the other end of it.       

     In a typical arrangement, there are at least two hinge sets, and often three, that support a door  400  in a door frame  402  before it is decided to add the support of a cabinet to those hinges. These hinge sets are then identified as hinge sets A. 
     Hinge sets A each have three parts. They are: hinge part W (hpW) is secured to the door frame, the hinge part X (hpX) which is secured to door, and the standard hinge pin P pivotally connecting these hinge parts through their cylindrical ends. Each of the hinge parts W (hpW) has a vertically extending cylindrical end CeW, and each of the hinge parts X (hpX) has a vertically extending cylindrical end CeX. The hinge part W (hpW) is so mounted on the door frame that its vertically extending cylindrical end CeW is underneath the cylindrical end CeX. These cylindrical ends have axes aCeW and aCeX that are in vertical alignment. There is also a standard hinge pin P that extends through both of those cylindrical ends CE, and the axis aP of the standard hinge pin is also in vertical axial alignment with the axes aCeW and aCeX, allowing the door to swing horizontally about the aligned axes of those hinge parts. The hinge part X&#39;s cylindrical end CeX is usually located above the cylindrical end CeW of the hinge part W (hpW). 
     When the cabinet is to be mounted on the same hinges that are already supporting the door, the hinge sets B may be created for temporarily holding the door  400  in place relative to the door frame  402 , until hinge sets C can be put together. The hinge part W (hpW) is still used as a part of the Hinge sets B, but the hinge part X (hpX) is replaced by the hinge part Y (hpY), because a different type of fastening of the hinge parts that are attached to the cabinet that have to be connected to the door frame. These hinge parts are known as part Y (hpY). Therefore Hinge Sets B are made up of hinge parts W and Y (hpW and hpY), and a hinge pin. Since hinge parts W remain on the door frame, its Cylindrical end CeW remains in its axially vertical position, and the hinge part hpY is added to the creation of each of the hinge sets B, with its cylindrical end CeY being located over the cylindrical end CeW, and the hinge pin P is reinserted inserted axially through the aligned cylindrical ends. With this combination of hinge parts, the door  400  still is mounted to be moved horizontally in an arc about the vertical axis with which the cylinderical ends CeW and CeY are also vertically aligned, but it is now ready to receive hinge parts. These hinge sets B operate identically to hinge sets A until the cabinet is to have its hinges also connected with the door frame. 
     To begin the operation of placing the cabinet in pivotal support with the door frame hinge parts Y, the hinge sets C are created. There are at least two of the hinge sets C. The cabinet&#39;s hinge part Z is secured to the cabinet, and, with the hinge pin P removed, has its cylindrical end CeZ placed over the cylindrical end CeY, and in axial alignment with it, The elongated hinge pin Q is then inserted through those three aligned cylinder ends, starting at the top, until its head rests on the top of the cylinder end CeZ. Now, each group of hinge sets comprises the hinge part Z (hpZ), the hinge part Y (hpY), and the hinge part W (hpW), one being secured to the cabinet, and one being secured to the door, and the third one being secured to the door frame and supporting the other two hinge parts. 
     If the cabinet is at least almost as high as the door&#39;s height, it may be pivotally secured to the door frame with two hinge sets C, whether the door itself is pivotally supported by two or three of the hinge sets B, or two of hinge sets B and one of hinge set A. If the cabinet is considerably less high than the door&#39;s height, it would usually be supported by two hinge sets C, which would be associated with two of the hinge sets B for the door, with another hinge set, either B or A, being the lowest one of the three hinge sets that support the door only, assuming that the cabinet is to be mounted higher than that lowest hinge set B or A. In this arrangement, since it will be known before that two of the three hinge sets are to be prepared to support the cabinet by first converting the two higher hinge sets A to hinge sets B, and that the lowest hinge set of three hinge sets mounting the door on the door frame will not be involved, it would be necessary, and economically feasible, to leave that lowest hinge set as a hinge set A. Then, when the cabinet is ready to be mounted to also pivot on the door frame, those two hinge sets B are converted to hinge sets C. 
     When the cabinet is about to be hung while all of the hinge sets supporting the door on the door frame are hinge sets A, the momentary creation of hinge sets B is usually omitted, and the two upper hinge sets A are directly changed into hinge sets C. 
     When the door is supported on the door frame by only two hinge sets A, then the cabinet must be of such vertical height that it extends upwardly beyond the horizontal location of the upper hinge set A, and downwardly beyond the horizontal location of the lower hinge set A. Then all of the hinge sets A will be converted either to hinge sets B on a short-term basis, and then will be further converted to hinge sets C, or the hinge sets A will be directly converted to hinge sets C when the cabinet with its hinge parts secured to it, and as it is being hung on the hinges secured to the door frame. 
     A summary of specifically claimed features of the invention, particularly and as are primarily provided in the independent claims filed, is as follows: 
     One, or both, of the cabinet side panels have a plurality of vertically aligned slots. The cabinet has hinges that are in part modified by providing a longer hinge pin. The modified hinges have the hinge sections thereof attached to one side of the cabinet side panels through the slots formed therein so as to adjust to the vertical location of the door, with the one hinge section having at least two cylindrical ends through which the longer hinge pin can be fitted while the two cylindrical ends are spaced so that they can mate with the standard hinge parts that are mounted on the door frame and can have the cylindrical part of each of the standard hinge parts receiving at least one of the cylindrical parts of the door hinge part affixed to the door frame, with the longer hinge pin being sufficiently long to extend through the cylindrical parts of the hinge parts affixed to the door frame. The cylindrical parts are parts of the modified hinge part secured to the door, so that the cabinet is adapted to be connected to the door frame by the hinges that are so connected to the door frame and the door, to the extent that the cabinet is able to be pivoted about the longer hinge pins relative to the door. 
     The cabinet has a back panel that is formed in at least one curve about a vertical axis and throughout a horizontal arc of no more than about 180°. The at least one curve is an arc of a circle whose radius is between one (1) time and twenty (20) times as large as the depth of the cabinet from the center of the arc to the front of the cabinet assembly. 
     The cabinet assembly, in which the first and second side panels each respectively have first and second vertical edges and the curved back panel, has first and second vertically extending outside edges which are respectively secured to the first and second vertical edges of first and second side panel vertical edges. 
     The cabinet&#39;s back panel curve extends outwardly to the lateral distance defined by the cabinet side vertical edges and then extends in a planar manner in parallel from the back panel curve to the cabinet side vertical edges. 
     The cabinet and a door having a door frame have a plurality of hinge sets which independently support the cabinet and the door on the door frame. Each of the hinge sets has a hinge pin which has an axially extending center. There is a separate first hinge part that has first and second ends, with the first end being firmly attached to the door frame. There is also a separate second hinge part having first and second ends, with the first end thereof being firmly attached to the cabinet. There is also a separate third hinge part having first and second ends, with the first end thereof being connected to the door. Each of the second ends of the separate hinge parts has a cylindrical end receiving the hinge pin for independent pivotal movements about the hinge pin&#39;s axially extending center. The hinge sets each allow the door to be moved in door opening and closing directions relative to the door frame without causing coextensive pivotal movements of the cabinet relative to the door. The hinge sets also allow the cabinet to be moved about the hinge pin in opening and closing directions relative to the door by pivotal movements relative to the door and to the door frame, without causing pivotal hinge movements of the door relative to the door frame. 
     The invention in an additional sense is also an improvement in the above mounting at least two different structures which are each mounted by a plurality of hinge sets on a door frame for pivotal movements relative to the door frame. Each of the hinge sets includes a hinge pin and a hinge part secured to a first one of the at least two different structures. Another one of the hinge parts is secured to the door frame, and the hinge parts are connected together by a hinge pin so that the first one of the at least two different structures can be moved arcuately relative to the door frame. The first structure is a door fitting in the door frame, and the second structure is a cabinet that has a second plurality of hinge parts secured thereto. Each of the second plurality of hinge parts also receives the hinge pin so as to be connected by means of that hinge pin in a pivotal connection that allows the second structure to be arcuately movable independently of the first structure instead of being required to arcuately move with it. 
     The improvement in mounting the at least two different structures for independent pivotal movements relative to the door frame further comprises a third structure that is a part of the at least two structures. The third structure has a third plurality of hinge parts secured thereto. These hinge parts receive the hinge pin so as to be connected via the hinge pin in pivotal connection in the manner that allows the third structure to also be arcuately movable independently of the first one of the at least two structures and the second one of the at least two structures being required to arcuately move with it. 
     More specifically, the first structure is a door, the second structure is a cabinet, and the third structure is a mirror, with each of the three structures being independently pivotally movable about the hing pin through arcuate movements sufficient to permit the independent use of the cabinet and the mirror to at least a limited extent of about 45° of such independent movement relative to the door frame. 
     The invention is also characterized as a method of mounting a door and a cabinet on a door frame so that they are independently able to be moved to some extent relative to the door frame, with the method comprising these steps: Step (A) provides at least two hinge sets that each pivotally support a door and a cabinet on a door frame in a manner that the door and the cabinet pivot about one common hinge axis, each of the hinge sets having first and second and third parts and a hinge pin. Step (B), provides each of the hinge sets with a longer-than-standard-length hinge pin than the standard length hinge pin that is commonly used when only a door is being attached to a door frame using hinge sets. In step (C), the a first part of each hinge set is secured to the door frame. In step (D) a second part of each hinge set is secured to the door. In step (E), a third part of each hinge set is secured to the cabinet; and, in step (F), the hinge pin is inserted through openings of each of those hinge parts that are adapted to receive the hinge pin therethrough along a common axis. This results in having pivotally mounted the door and the cabinet for separate pivotal movements relative to the door frame about the hinge pin. 
     That method more particularly also includes the following additional details of certain steps: In step (C), providing the first part of each hinge set with one section for securing it to the door frame, providing another section of the first part with a cylindrically shaped opening for receiving a hinge pin; and securing only the one section of the first part of each hinge set to the door frame; in step (D) providing the second part of each hinge set with one section for securing it to the door, providing another section thereof with a cylindrically shaped opening for receiving a hinge pin, and securing only the one section thereof to the door; in step (E) providing the third part of each hinge set with one section for securing it to the cabined, providing another section thereof with a cylindrically shaped opening for receiving a hinge pin, and securing only the one section thereof to the cabinet; and in step (F), arranging the cylindrically shaped openings of each of the parts of each hinge set in axial alignment and inserting the hinge pin through each of the cylindrically shaped openings.
