Title: Pivotally mountable hinge part having quick assembly hinge sections and method of using same

Description:
BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      This invention relates to a pivotally mountable hinge part having quick assembly members for pivotally mounting a rigid substrate, e.g. pivotally mounting a window to an automotive body, and more particularly, to a pivotally mounted hinge part including an injectable member or injector optionally pivotally mounted to the back end of an automobile inserted into a receiving member or receiver optionally mounted on a rear automotive window, to secure, e.g. releasably secure, the receiver and injector together to pivotally mount the window to the automotive body. The invention also relates to a method of using the hinge part having the quick assembly members, i.e. the receiver and the injector.  
      2. Discussion of the Technology  
      Hinges of particular interest in this discussion include a first rigid hinge part and a second rigid hinge part. A side of each hinge part has spaced protrusions having a passageway. The protrusions of the parts interlock, and in an aligned position, a pin is inserted into the passageway to pivotally mount the hinge parts. As is appreciated by those skilled in the art, the first and second hinge parts can be plates secured to the pieces to be pivotally mounted together. In other instances, the protrusions having the passageway can be formed with one of the pieces to be pivotally mounted and the other hinge part joined to the other piece to be pivotally mounted. By way of illustration, an automotive body has the protrusions on which a hinge part is pivotally mounted formed as part of the automotive body and has hinge parts that are adhesively bonded to, welded to, bolted to, or screwed to the automotive body. The other hinge part can be secured to, or formed with, the piece to be pivotally mounted to the automotive body.  
      Consider now the arrangement for moveably mounting windows to automotive bodies. Automobiles are presently available with side doors and rear doors. The windows can be mounted on an elevator arrangement mounted within the door to move the windows up and down, the windows can be pivotally mounted to the automotive body, e.g. quarter panels mounted as discussed in U.S. Pat. No. 5,551,197, the windows can be pivotally mounted to the window opening of sliding side door, the windows can be pivotally mounted to the window opening of the rear door and/or the window can be pivotally mounted to the rear portion of the automotive body. Of interest in this discussion is the replacement of windows that are pivotally mounted in the window opening of the automotive body or pivotally mounted to the automotive body.  
      More particularly, in the instance where the hinge pivotally mounting the window is adhesively bonded to the rear window, the window is replaced by removing the fastener that pivotally mounts the window to the automotive door or to the automotive body. In the instance when the window is secured to the hinge by mechanical fasteners, e.g. a nut and bolt assembly, the nut and bolt assembly of each hinge is separated to replace the broken window with a new window. Windows having the hinge part secured by mechanical fastener have an additional limitation. More particularly, over tightening the nut and bolt arrangement can result in breaking the glass window. The replacement of windows that are pivotally mounted at the same pivot position as the automotive door, e.g. the rear door, such that the window can be opened and closed with the door in the closed position and can be opened with the door in the open position, is more labor intensive because the pin that pivotally mounts the hinge part for the door and for the window has to be removed to remove the broken window and inserted to pivotally mount the door and the replacement window.  
      As can be appreciated, it would be advantageous to provide a hinge part that does not have the limitations of the presently available hinge parts used to pivotally mount pieces together, e.g. pivotally mount windows to automotive bodies or to window openings of doors.

The injector  92  includes a body  96  with upper end portion or upper end  97  of the body  96  having a pair of spaced extensions  98 . The distance between the extensions  98  is equal to or greater that the length of the cylindrical member  41  mounted to the body  32  of the automobile  22 , and the thickness of the outer legs  38  of the U-shaped hinge member  36  of the hinge part  34  mounted to the top of the door (see  FIGS. 1 and 2 ). With this arrangement hinge part  90  of the invention, e.g. the injector  92  of the hinge part  90  can be pivoted about the pin  42  (see  FIG. 3 ) to lift the rear window  24  toward and/or into the open position, and lower the rear window toward and/or into the closed position when the door is closed and/or when the door is being opened or closed. The body  96  of the injector  92  is shaped to provide a smooth transition from the cylindrical member  41  to the window  24 . Although not limiting to the invention, the body  96  of the injector  92  has a hole  100  for securing a cover plate  101  (shown only in  FIGS. 2 and 3 ) to the body  96  in any manner, e.g. by a nut and bolt assembly to cover the cylindrical member  41  and portions of the injector for an aesthetic appearance.  
      Lower end portion or opposite side  102  of the body  96  has a pair of spaced fingers  104  and  106 . The distance between the fingers increases as the distance from the body  96  increases with the fingers terminating with outwardly extending tabs  108  and  110 . The width and/or thickness of the fingers  104  and  106  are sized to move toward one another under a biasing force and to move back to the unbiased position after the biasing force is removed. For example and not limiting to the invention, an injector was molded from polybutylene terephthalate (also referred to as “PBT”). The fingers had a length of about 62 millimeters (“mm”) and a width of about 20 mm with a slight decrease in the width as the distance from the upper end  97  of the body  96  toward the tabs increases. The fingers adjacent the body  96  had a spaced distance of 40 mm and a spaced distance at the tabs of 63 mm. The fingers and tabs each had a thickness of about 5 mm.  
      Although not limiting to the invention, the portion  111  of the body  96  between the end portions  97  and  102  is recessed within sides  112  and co-operates with the cover plate  101  (see  FIGS. 2 and 3 ) to receive the hinge part  34  of the door  23  for an aesthetic appearance.  
      The receiver  94  includes a passageway  113  extending from upper side  112  through body  114  of the receiver  94 . Within the passageway are a pair of projections or nibs  116  facing one another, spaced from one another and spaced from the side  118 , e.g. bottom side  118  as viewed in  FIG. 5 a  distance to receive the tabs  108  and  110  of the fingers  104  and  106  respectively. The passageway  113  is sized to receive the fingers in the unbiased position. As the tabs  108  and  110  of the fingers  104  and  106  move into the passageway  113 , the tabs  108  and  110  engage their respective nib  116 . Continued urging of the fingers into the passageway applies a biasing force to the fingers to move the fingers toward one another as the tabs slide over their respective nib. After the tabs of the fingers pass over the nibs, the fingers move away from one another to their unbiased position to move the tabs into groove  119  to releasably or detachably secure or lock the injector  92  and the receiver  94  together to provide a non-limiting embodiment of a hinge part having the quick assembly receiver and injector of the invention.  
      As can be appreciated, the invention is not limited to the process of making, or the material used in the process of making the receiver and the injector of the invention. For example and not limiting the invention thereto, the injector  92  and the receiver  94  can be made of any material, e.g. but not limiting the invention thereto metal, plastic, plastic reinforced fiberglass, composite material, wood or combinations thereof that can be flexed under a biasing force and after the biasing force is removed the fingers return to their unbiased position. Stated another way, the material selected should have a mechanical yield greater than the biasing force to be applied to the fingers. Further, the injector  92  and the receiver  94  can be made of the same material or different materials. The injector and the receiver can be made in any manner, e.g. the parts can be machined, formed, e.g. press formed, injection molded, cast, forged, extruded or pultruded, or assembled from machined or formed component parts. As can be appreciated in selecting the material and assembling the parts consideration has to be given to the structural stability of the design and material. In the practice of the invention the engaging member and receiver were formed by injection molding PBT purchased from GE Polymer. Regarding the structural stability of the design and stresses acting on the engaging member and the retentive member, computer programs are available to determine adequate design criteria. One such computer program is available from Altair Engineering of Troy, Mich., and is known by the name Hypermesh®.  
      The receiver  94  is securely mounted on the inner surface  52  of the window  24  (see  FIG. 4 ) in any usual manner, e.g. but not limiting the invention thereto, holes can be drilled in the glass piece during the process for making the window  24 , and a nut and bole assembly used to secure the receiver to the window, or the receiver can be adhered to the window using a layer of any type of adhesive or a double sided tape having any type of adhesive layer on each side. In the practice of the invention, a receiver of the type shown in  FIG. 5  was secured to a glass window using a two-component urethane adhesive sold by Dow under the name of Betamate® 73100/73005.  
      The receiver  94  and the injector  92  are separated or released from one another in any convenient manner, e.g. but not limiting to the invention an elongated member  120  (only one shown in  FIG. 5 ) is inserted into each of the slots  121  in the bottom side  118  of the receiver  94  and into hole  122  in the bottom of each tab  108  and  110  of the fingers  104  and  106 , respectively. The elongated members  120  are moved toward one another to bias the fingers  104  and  106  toward one another to move the tabs  108  and  110  out of their respective groove  119 , clear of their respective nib  116 . The injector  92  and the receiver  94  are moved relative to one another, e.g. but not limiting to the invention, the receiver is moved away from the injector. After the tabs pass their respective nib, the elongated members  120  can be removed from their respective hole  122  in the tab and the slot  121  in the bottom side of the receiver. The fingers are removed from the passageway, and the receiver and the injector separated from one another.  
      It should be appreciated that in one nonlimiting embodiment of this invention, the fingers  104  and  106  can be mechanically biased toward each other to facilitate engaging tabs  108  and  110  with nibs  116  in a manner similar to that discussed above where the fingers  104  and  106  were mechanically biased to disengage tabs  108  and  110  from nibs  116 .  
      As can be appreciated by those skilled in the art, the invention is not limited to the tool to bias the fingers  104  and  106  toward one another to separate the injector  92  and the receiver  94 . For example but not limiting the invention thereto, the tool can use the mechanical arrangement of a pair of pliers to move the jaws of the pliers together. To move the tabs out of their respective groove, the jaws of the pliers would be replaced with, or reshaped to have the shape of, elongated members  120 . Further the receiver  94  is shown in  FIG. 5  to have a closed bottom side  118 . As can be appreciated, the side  118  can be an open ended side of the passageway  113 .  
      The hinge part of the invention having the quick assembly receiver and injector makes the removal and replacement of the rear window a simple process. More particularly, when the removal of the window is desired, e.g. to replace a damaged window, to carry cargo or for convenience, the end  74  of the piston rod  76  is removed from the plate  78 , and the receiver and the injector separated as discussed above. A replacement window or the window removed is mounted to the injector by moving the fingers  104  and  106  of the injector into the passageway  113  of the receiver to move the tabs  113  into their respective groove  119  as discussed above. The end  74  of the piston rod  76  is connected to the plate. In the alternative, the end  70  of the piston  68  can be removed from the door to remove the piston  68  with the window.  
      Although not limiting to the invention and with continued reference to  FIG. 5 , the injector  92  can be provide with a plate member or collar  123  from which the fingers  104  and  106  extend. The collar  123  is sized to snugly fit into the passageway  113  at the side  112  of the receiver  94  when the tabs  108  and  110  of the fingers  104  and  106 , respectively are in their respective groove  119 . The collar  123  inserted into the receiver  94  limits rocking of the fingers  104  and  106  of the injector  92  when the injector is in engagement with the receiver  94 .  
      In the discussion of the invention, the hinge part of the invention and the hinge part of the door are mounted on the same cylindrical member  41  by the same pin. The invention contemplates mounting the hinge part of the door and the hinge part of the invention on separate cylinders using the same pin or different pins. Further the invention contemplates mounting the receiver or the injector on the inside surface or the outside surface of the window.  
      As can now be appreciated, the quick release receiver and injector of the invention are contoured and fitted to blend in with the shape of the window and the contours of the automotive body parts to provide an atheistically pleasing appearance, an aerodynamically acceptable shape and to reduce stress on the parts of the hinge due to changes in contour. These features are well known in the art and no further discussion regarding these matters is deemed necessary.  
      With reference to  FIG. 6 , there is shown another non-limiting embodiment of the hinge part having the quick assembly receiver and injector of the invention designated by the number  130 . The hinge part  130  includes an injector  132  and receiver  134 . Upper end portion  135  of body  136  of the injector  132  for pivotally mounting the hinge part  130  to the automobile body is not shown in  FIG. 6 ; however, the discussion regarding the upper end portion  97  of the injector  92  shown in  FIG. 5  and its attachment to the automobile body is applicable to attach the injector  132  to the automobile body. Lower end portion  137  of the body  136  of the injector  132  includes a pair of fingers  139  and  140  spaced from one another with an aligning member  142  between the fingers. Each of the fingers  139  and  140  has an outwardly extending tab  144 .  
      The receiver  134  has a passageway  145  having an opening at side  146  of the receiver  137  and extends into body  147  of the receiver to three passageways  148 ,  149  and  150  separated by members  155  and  158 . Although not limiting in the present invention, in the particular embodiment members  155  and  158  are spaced apart a distance slightly greater than the width of alignment member  154 . The passageways  148 ,  149  and  150  extend through the body  147  to side  151  opposite to side  146 . The outer passageways  148  and  150  each have a nib  152  to capture the tabs  144  of the fingers  139  and  140  in a manner discussed below to releasable secure the injector  132  and the receiver together. The middle passageway  149  receives the alignment member  142 . Although not limiting to the invention, receiver  134  has a side cavity  153  to reduce the amount of material needed to form the receiver. End  154  of the alignment member  142  has rounded or mitered corners, and end  156  of the fingers  139  and  140  is rounded for ease of insetting the alignment member and fingers in their respective passageways, and for moving the tabs of the fingers  139  and  140  over their respective nib  152  to move the fingers toward one another. After the tabs  144  move over their respective nib, the fingers  139  and  140  move to their unbiased position. As the fingers move toward their unbiased position, outwardly facing groove  157  of the fingers  139  and  140  move over the adjacent nib to lock or secure the injector  132  and the receiver  34  together. The ends  156  of the fingers  139  and  140  are provided with the holes  120  to allow for biasing of the fingers  139  and  140  toward one another so as to move the tabs over its respective nib as the receiver and the injector are separated. With the nibs  152  in its respective groove  157  of the fingers  139  and  140 , plate member or shoulder  159  of the injector  132  is in the passageway  145 . The alignment member  154  facilitates the alignment of the fingers with their respective passageway. The shoulder  159  of the injector in the passageway of the receiver  134  and the alignment member  142  in the passageway  149  reduces rocking of the injector  132  and the receiver  134  relative to one another.  
      There is shown in  FIG. 7 , still another non-limiting embodiment of the hinge part having the quick assembly receiver and injector of the invention designated by number  160 . The hinge part  160  includes a receiver  162  and an injector  166 . The injector  166  is mounted on a surface of the window  22 , e.g. the inner surface  52  the window  26 . The injector  166  includes a pair of outer alignment members  168  and  169  and two spaced fingers  171  and  172  between the spaced members  168  and  169 . The fingers  171  and  172  each have an outwardly extending tab  174 . The injector can be mounted on the glass with the alignment members  168  and  169 , and the fingers  171  and  172  extending beyond the edge of the window as shown in  FIG. 7 , or the alignment members and fingers can be located over and spaced from the glass surface so that the receiver  162  can receive the alignment members and the fingers in a manner discussed below.  
      In the arrangement of  FIG. 7 , the receiver  162  of the hinge part  160  includes a body  175  having hollow cylinder  176  mounted to the upper portion of the body  175 . Extensions  176  are mounted on the automobile, and the pin  42  passes through the extensions  177  and the cylinder  176  to pivotally mount the receiver  162  to the body of the automobile. The hinge part  34  of the door  23  (not shown in  FIG. 7 ) is pivotally mounted to the roof at positions spaced from the positions at which the window is pivotally mounted. The lower end portion  178  of the body  175  of the receiver has a pair of outer passageways  179  and  180  to receive the outer alignment members  168  and  169  respectively, and a center passageway  181  having a nib  182  on each of opposed walls  183  and  184  of the passageway  181  to capture the tabs  174  of the fingers  171  and  172  as previously discussed for the hinge  90  as shown in  FIG. 5 . The receiver  162  and the injector  166  are joined together by sliding the alignment members  168  and  169  into the passageways  179  and  180 , respectively, and the fingers  171  and  172  into the center passageway  181  to move the tabs  174  over the nibs  182 . The receiver  164  and injector  166  are separated by inserting end of an elongated rod (shown only in  FIG. 5 ) through horizontal groove  186  as viewed in  FIG. 7  into hole  190  in each of the nibs  174  of the fingers  171  and  172 . The elongated rods are moved toward one another along the horizontal groove  186  to bias the fingers toward one another to clear its respective nib  181 . Thereafter, the receiver and the injector are moved away from one another. The elongated rods move along vertical grooves  192  as viewed in  FIG. 7  (only one shown in  FIG. 7 ) and the fingers move out of the passageway  181 , moving the tabs  174  past their respective nib  182 . Thereafter the elongated rods can be removed from the holes  190  in the tabs and from the vertical groove  192 , and the injector  166  and receiver  162  are separated. As can be appreciated, the horizontal groove  186  and vertical grooves  192  can be combined into an opening large enough to bias the fingers toward one another and maintain the fingers toward one another as the tabs move past their respective nibs  182 .  
      As can be appreciated, the invention is not limited to the non-limiting embodiments of the quick assembly hinge discussed above, and the invention contemplates arrangements having one or more receivers and/or one or more injectors. For example but not limiting to the invention, hinge part having the quick assembly receiver and injector shown in  FIG. 8  and designated by the number  200  includes a receiver  202  and two injectors  204  and  206 . One side, e.g. side  208  of the receiver  202  is connected to the injector  204  and the other side, e.g. side  210  is connected to the second injector  206 . Body  212  of the injector  204  has a pair of spaced extensions or a cylinder (neither shown) at side  213  similar to the spaced members  98  of the hinge  90  shown in  FIG. 5  or the cylinder  41  of the hinge  160  shown in  FIG. 7  for pivotally mounting the injector  204  to the automobile. Opposite end portion  216  of the body  212  of the injector  204  has a pair of fingers  217  and  218  having inwardly facing tabs  219 . The second injector  206  has body  220  securely mounted to the inner surface  52  of the window  26  as discussed above. The body  220  of the injector  206  has a pair of spaced fingers  222  and  223  each having inwardly facing tabs  224 .  
      The receiver  202  has a pair of passageways  230  and  232  extending from the side  208  to the side  210 . A wall  238  separates the passageways  230  and  232  and has on each side a pair of spaced nibs, namely nibs  240  and  241  on one side of the wall  238  and facing the passageway  230 , and nibs  243  and  244  on the wall and facing the passageway  232 . As shown in  FIG. 8 , when the fingers  217  and  218  of the injector  204  are inserted in the side  208  of the receiver into the passageways  230  and  232 , respectively, the tabs  219  of the fingers  217  and  218  pass over the nibs  240  and  241 , and the fingers  217  and  218  are captured in the receiver  202 . Similarly, when the fingers  222  and  223  of the injector  206  are inserted in the side  210  of the receiver into the passageways  230  and  232 , respectively, the tabs  224  of the fingers  222  and  223  pass over the nibs  243  and  244 , and the fingers  222  and  223  are captured in the receiver  202 . In this manner, the injectors  204  and  206 , and the receiver  202  are releasable secured together to pivotally mount the window  24  to the body of the automobile.  
      The fingers  217  and  218  of the injector  204 , and the fingers  222  and  223  of the injector  206  can be removed from their respective passageways in any convenient manner, e.g. by moving the fingers, e.g. fingers  217  and  218  away from one another and/or the fingers  222  and  223  away from one another, e.g. using the groove arrangement, e.g. horizontal groove  186  and vertical groove  192  shown in  FIG. 7 .  
      As can be appreciated, the position of the receiver  202  and the injectors  204  and  206  can be interchanged. For example, but not limiting to the invention, a receiver can be pivotally mounted to the body of the automobile, and another receiver secured to the glass. An injector having a pair of spaced fingers with outwardly facing tabs at opposite sides secures the two receivers together to pivotally mount the window on the body of the automobile.  
      Other embodiment of the hinge part having the quick assembly receiver and injector of the invention contemplates different arrangements to secure the tabs of the injector in the receiver. For example, but not limiting to the invention, and with reference to  FIG. 9 , the locking arrangement for hinge part designated by the number  250  includes receiver  252  having a “T” shaped passageway  253 . The passageway  253  has an open end portion  254  having inwardly sloping walls  256  extending toward side  257  of receiver  252 , which intersects portion  258  of passageway  253 . Portion  255  extends the width of receiver  252  and includes openings  259  and  260  in each sidewall of the receiver forming a ledge  266 . As fingers  263  and  264  having outwardly extending tabs  267  are moved into portion  254  of the passageway  253 , the tabs  267  engage the inwardly sloping walls  256  of the passageway  253  to bias the fingers  263  and  264  toward one another. When the tabs move past the transition position  258 , the biasing action on the fingers is removed and the tabs of the fingers move into their respective adjacent one of the openings to secure the injector and the receiver together.  
      The tabs  267  of fingers  263  and  264  are removed from portion  258  of passageway  253  in any convenient manner, e.g. by moving an end of an elongated rod (not shown) through the side of the receiver  252  into each of the openings  259  and  260 , respectively into engagement with the tabs  267  of the fingers  263  and  264 . The rods are moved toward one another to move the tabs  267  to a position such that tabs  267  can move through portion  254  and the injector and the receiver can be moved away from one another to separate them. As can be appreciated the tabs can be provided with holes for a more positive engagement between the end of the rod and the tabs.  
      With reference to  FIGS. 10 and 11 , there is shown another non-limiting embodiment of the hinge part having the quick assembly receiver and injector of the invention designated by the number  270 . The hinge part  270  includes a receiver  271  and an injector  272 . The receiver  271  or the injector  272  can be pivotally mounted on the body  32  of the automobile  22  as previously discussed, and the injector  272  or receiver  271  can be secured to the window  26  as previously discussed. The receiver  271  includes a housing  274  having an open end  275  to receive the injector  272 , and a flexible finger  276  biased toward interior  278  of the housing  274 . The finger  276  has an extended ridge or ledge  280  (clearly shown in  FIG. 11 ) that is seated in groove  281  of the injector  272  when the injector is inserted into the housing  274  of the receiver  271  as discussed below.  
      The injector  272  includes a plate member  282  having a bottom surface  284  and an opposite upper surface  285 . The upper surface  285  has the groove  281  spaced from end  286  of the plate member  282 . Portion  288  of the upper surface  285  between the groove  281  and the end  286  of the plate member  278  slopes downward for ease of inserting the end  286  into the housing  274  of the receiver  271 . Remaining portion  289  of the upper surface  285  of the plate member  282  on the other or left side of the groove  281  as viewed in  FIGS. 10 and 11  is preferably, but not limited to the invention, sized to slide into the housing  274  and have minimal spacing, e.g. 1/32 to 1/16 inch between the interior walls of the housing  274  and exterior surfaces of the plate member  282  on the left side of the groove  281  as viewed in  FIGS. 10 and 11 . In this manner, there is minimal rocking of the plate member when captured in the housing and less fatigue wear on the ledge  280  of the finger  276  of the receiver  271 .  
      In the practice of the invention, but not limiting thereto, the end  286  of the injector  272  is moved into the housing  274  of the receiver  271  and moves the flexible finger  276  upward as shown in phantom in  FIG. 11  as the ledge  280  slides along the sloped surface  288  of the injector  272 . When the groove  281  moves under the ledge  280 , the biasing action of the finger  276  moves the finger downward to move the ledge into the groove  281  of the injector  272  to releasably secure the plate member  282  in the housing  274 . The plate member  282  is removed from the housing  274  in any convenient manner, e.g. but not limiting the invention, bent end  290  of elongated member  291  (see  FIG. 11 ) is placed in hole  292  of the ledge  280 , and the elongated member  291  moved away from the housing  274  to lift the finger  280  and move the ledge  280  out of the groove  281 . The plate member  282  is moved out of the housing  274  to separate the receiver  271  and the injector  272 .  
      With reference to  FIGS. 12, 12A  and  13 A- 13 C as needed there is shown another non-limiting embodiment of a hinge part designated by the number  330  having the quick release injector  332  and receiver  334  of the invention. The injector  332  of the hinge part  330  has a body  336  having an upper end portion  338  and a lower end portion  340  as viewed in  FIG. 12 . The upper end portion  338  has the extensions  98  to pivotally mount the injector  332  to the cylinder  41  by the pin  42  in a similar manner as the extensions  98  of the hinge part  90  shown in  FIG. 5  are mounted to the automobile  22  (shown in  FIGS. 2 and 3 ). The lower end portion  340  of the body  336  of the injector  332  has a plate member  342  connecting the body  336  of the injector  332  to an engaging arrangement  344 . The engaging arrangement  344  includes a pair of grooves  346  that terminates short of end  348  of the engaging arrangement  344  to provide spacings  350  between ends of fingers  352 ,  353  and  354  to release the receiver  334  from the injector in a manner discussed below. Although in the practice of the invention, the middle finger  353  is wider than the outer fingers  352  and  354 ; the invention is not limited thereto, and the fingers can be of equal width, unequal width, or the outer fingers wider than the middle finger.  
      Adjacent the end  348  of each of the fingers is a cutout  356  to engage the receiver  334  in a manner discussed below. As shown in  FIGS. 13A-13C  the thickness of the fingers  352 ,  353  and  354  decreases as the distance from the plate member  342  decreases to a bending location  358 . With reference to  FIG. 13A  with the fingers in the unbiased position, the end  348  and the cutout  356  of each finger  352 ,  353  and  354  are below plane  362  in which bottom surface of the plate member  342  lies. The fingers  352 ,  353  and  354  have sufficient flexibility to move the end  348  of each finger upward as viewed in  FIG. 13A  in a manner discussed below to bend the fingers at the bending location  358  into a biased position shown in  FIG. 13B  and discussed below.  
      The receiver  334  has a passageway  370  for receiving the engaging arrangement  344  of the injector  332 . End  371  of wall  372  of the passageway  370  terminates short of end  374  of the receiver. A portion of the wall  372  has a pair of spaced grooves  376  (one shown in insert  12 A) along passageway  370  that align with the spaced grooves  346  of the engaging arrangement  344  of the injector  332  when the injector and the receiver  334  are in the engaged position discussed below and shown in  FIG. 13C . The engaging arrangement  344  of the injector and the passageway  370  of the receiver are sized such that complete insertion of the engaging arrangement in the passageway has the body  336  of the injector  332  adjacent side  378  of the receiver, and the cutout  356  of each finger  352 ,  353  and  354  engaging end  371  of the wall  372  as shown in  FIG. 13C .  
      With reference to  FIGS. 13A-13B  as needed, the end  348  of the engaging arrangement  344  of the injector  332  is moved into the passageway  370  of the receiver in the direction of arrow  380  toward the side  378  of the receiver  334 . As the body  336  of the injector follows the engaging arrangement into the passageway  370  of the receiver  334 , the end  348  engages inner surface  382  of the wall  372  of the passageway  370  and is biased upward in the direction of the arrow  384 . Continued movement of the engaging arrangement  344  into the passageway moves the body  336  of the injector  332  adjacent the side  378  of the receiver  334 , and the end  348  of the fingers  352 ,  353  and  354  over the end  371  of the wall  372  of the passageway  370  of the receiver to move the fingers to the unbiased position and move the cutouts  356  in the fingers into engagement with the end  371 . In this manner the receiver and the injector are detachably secured together.  
      The injector  332  is released from the receiver  334  in any convenient manner. For example, but not limiting to the invention, by inserting an elongated member  386  shown in  FIG. 13C  into the grooves  346  between the fingers  352  and  353  and between the fingers  353  and  354  and into the grooves  376  of the receiver (see  FIGS. 12 and 12 A). The elongated members (only one shown in  FIG. 13C ) are moved upward in the direction of the arrow  384  to move the fingers into the biased position and move the cutouts  356  of the fingers away from the end  371  of the passageway  370 . After the fingers of the injector clear the end  371  of the passageway, the injector and the receiver are pulled away form one another to separate the injector and the receiver.  
      The plate member  342  and the engaging arrangement  344  of the injector  332  and the passageway  370  of the receiver are sized such that the plate member  342  following the engaging arrangement into the passageway engages the inner walls of the passageway. In this manner, the ends of the fingers  352 ,  353  and  354  in surface contact with the inner walls of the passageway are biased upward about the bending location  358  into the biased position and move to the unbiased position after the ends of the fingers exit the passageway to move the cutouts  356  of the fingers over the side  374  of the passageway. Further minimizing the spacing between the inner walls of the passageway  370  and the outer surface of the plate member  342  of the injector  332  minimizes rocking to the injector and receiver relative to one another.  
      As can be appreciated, the outline of the receiver and injector should be configured to take into account the outline and surface of the window to which they are being mounted. For example but not limiting to the invention and with reference to  FIG. 12 , the length of side  390  of the plate member  342  is shorter than the length of opposite side  391 , and the length of side  394  of the receiver is shorter than the length of opposite side  395 . Further, and not limiting to the invention, the body  336  of the injector  334  and body of the receiver  334  are provided with cavities  397  for aesthetics and to reduce the amount of material needed to form the receiver and the injector.  
      The receiver and the injector shown in  FIGS. 12 and 13  were made using the process known as stereo lithographically. The passageway  370  of the receiver  334  had a width of 70 mm and a length of 60 mm; the wall  372  had a depth of 50 mm and the opposite wall  379  had a depth of 60 mm. The plate member  342  of the injector had a thickness of 8 mm, a width of 68 mm; the side  390  had a length of 25 mm and the side  391  had a length of 30 mm. The distance from the cutouts  356  of the fingers  352 ,  353  and  354  to the bending position  358  is 35 mm. The thickness of the fingers adjacent the cutouts  356  was 8 mm and the thickness adjacent the bending location  358  was 3 mm. The depth of the cutouts was sufficient to engage portions of the end  371  of the wall  372 .  
      As can be appreciated, the cutouts should be of sufficient depth to engage the end  371  of the wall  372  of the passageway  370  and the flexure of the fingers sufficiently rigid to avoid the cutouts from disengaging the end  371  as a result of vibrations. Further in those instances where the automobile is used on a rough or rocky terrain, the injector  332  may be secured in the receiver by a screw  396  shown in phantom in  FIG. 13C  passing through the wall  372  of the passageway through the plate  342  of the injector into the wall  378  of the passageway. The screw  396  can have a security cap to require removal of the screw by a special tool. In conjunction with the screw  396  or in place of the screw, a shim (not shown) can be provided in the passageway  370  between the fingers  352 ,  353  and  354  and the inner surface of the wall  378  and held in position by a screw (not shown).  
      Shown in  FIG. 14  is a still further non-limiting embodiment of the hinge part having the quick assembly receiver and injector of the invention designated by the number  400 . The hinge part  400  includes a first member  402  and a second member  404 . The first member  402  or the second member  404  can be pivotally mounted to the body  32  of the automobile  22 , and the member  404  or the member  402  may be secured to the rear window  26 , as previously discussed. The members  402  and  404  each having a saw toothed surface  406  that are interlocked as shown in  FIG. 14 . More particularly, teeth  408  of the saw toothed surface  406  of the member  402  are in grooves  410  of the saw toothed surface  407  of the member  404 , and teeth  412  of the saw toothed surface  407  of the member  404  are in the grooves  414  of the saw toothed surface  406  of the member  402 . As can be appreciated, either member  402  or  404  can be the receiver or the injector since both members have features of the injector and the receiver. More particularly, the teeth of the member are a feature of the injector and the groove between the teeth is a feature of the receiver. The members  402  and  404  are held together in any convenient manner, for example but not limiting to the invention, by screws  416  passing through passageways  418  in the member  402  and screwed into threaded holes  420  in the member  404 . As can be appreciated, the invention not limited to the manner in which the members  402  and  404  are secured together and any known fastening arrangement may be used, e.g. but not limiting to the invention, securing engaging strips sold under the registered trademark Velcro can be used to secure the member  402  and  404  together.  
      Shown in  FIG. 15  is still another non-limiting embodiment of the hinge part having the quick assembly receiver and injector of the invention designated by the number  440 . The hinge  440  includes a first member  442  and a second member  444 . The first member  442  or the second member  444  can be pivotally mounted to the body  32  of the automobile  22 , and the member  444  or the member  442  may be secured to the rear window  26 , as previously discussed. The member  442  or the member  444  has one part of a Velcro® attachment arrangement  446  adhered to a major surface, e.g. surface  448  of the member  442 , or surface  450  of the member  444 , and the member  444  or the member  442  has the other part of the Velcro attachment arrangement adhered to a major surface, e.g. surface  450  of the member  444 , or surface  448  of the member  442 .  
      The members  442  and  444  are secured together in any convenient manner to prevent pulling the Velcro arrangement apart, e.g. by the screw and bolt arrangement shown in  FIG. 14  or as shown in  FIG. 15  by mounting a rounded member  454  on each end portion of one of the members  442  or  444 , and receiving holes  456  in the other member  444  or  442 . An insert  458  having spaced legs (not shown) is moved into the holes  458  to move the end of the legs of the insert around the rounded member  454  to releasably secure or engage the member  454  in the hole  456 . Raising the insert  458  release the member  454 , and the members  442  and  444  can be separated by pulling the members apart with sufficient force to separate the Velcro arrangement.  
      With reference to  FIG. 16  there is shown an automobile  498  having additional non-limiting embodiments of the invention. More particularly, window  500  is pivotally mounted at  502  and  504  to topside  506  of window opening  508  of side door  510 . The window  500  can be pivotally mounted by mounting a receiver or injector of the invention discussed above to the top side  506  of the door  510  and mounting the injector or receiver, respectively of the hinge part to a surface, e.g. but not limiting to the invention, the inner surface (not shown) of window  500 .  
      With continued reference to  FIG. 16 , the invention can be used to pivotally mount quarter panel or side window  530  to the automotive body  498 . With reference to  FIGS. 16-18  as required, in the following discussion, the window  530  is pivotally mounted to the automotive body  498  by a pair of hinge parts  532  of the invention having the receiver  334  (see  FIG. 18 ), and an injector  534  similar to the injector  332  of the hinge part  330  shown in  FIGS. 12, 12   a  and  13 A- 13 C. The window  530  includes the ceramic band  81  on marginal edge portion of inner surface  536  to hide the receiver  334  from view from outside the automobile. A latch  538  is mounted on the inner surface  536  of the window  530  opposite the hinges  532  to open and close the window. The latch  538  is of the type used in the art and no further discussion is deemed necessary.  
      With specific reference to  FIG. 18 , the injector  534  has a lower end portion  540  similar to the lower end portion  340  of the hinge part  330  discussed above and shown in  FIGS. 12, 12A  and  13 A- 13 C mounted in the passageway  370  of the receiver  334  as discussed above for the hinge part  330 . Sides (not shown) of the end portion  540  of the injector  534  are equal in length unlike the sides  390  and  391  of the injector  332  shown in  FIG. 12  which are not equal in length. Upper body portion  542  of the injector  534  is curved and has a hole  544  to mount the injector  534  to section  548  of the automotive body adjacent the window opening. The injector is preferably made of spring steel and the curved upper body portion  542  is biased to move the window, e.g. the portion of the window having the latch  538  away from the section  548  of the automotive body. The receiver  334  can be made of any material. Moving the window  530  to the closed position, e.g. moving the portion of the window having the latch toward the section  548  of the automotive body, moves the window against the basing action of the upper body portion  542  of the injector  534 .  
      In the practice of the invention and not limiting to the invention, the upper body  542  of the injector  534  is secured to the section  548  of the automotive body  498  in any usual manner, e.g. by welding by a machine screw  550  as shown in  FIG. 18 . The end portion  540  of the injector  534  engages the receiver  334  to pivotally mount the window  530  to the automotive body  498 , and the end portion of the injector  534  disengages the receiver to remove the window from the automotive body in the manner that the injector  332  engaged and disengaged the receiver  334  discussed above and shown in  FIGS. 13A-13C .  
      In the above discussion, the tabs of the injectors of the non-limiting embodiments of the invention did not extend beyond the outer walls of the receiver. As can now be appreciated, the invention contemplates having portions of the tabs extending beyond the walls of the receiver, e.g. but not limiting to the invention, as shown for the hinge part  580  in  FIG. 19  having a quick assembly receiver  582  and injector  584  of the invention. The injector  582  includes a pair of fingers  586  and  587  each having a tab  590  having portions extending through holes  592  of the receiver  584 . The holes  592  extend from outer surface  594  of the receiver to passageway  596  in the receiver. In the practice of the invention, the flexible fingers  586  and  587  of the injector are moved into the passageway  596 . As the tabs  590  move into the passageway, the fingers  586  and  587  are biased toward one another. When the tabs  590  are aligned with their respective hole  592 , the tabs move through the holes as the fingers move to the unbiased position.  
      Because the tabs are easily accessible, it is recommended that a shim  600  be inserted into the passageway  596  between the fingers  586  and  587 . The shim is moved into the passageway of the receiver until hole  602  in the shim is aligned with hole  604  in the receiver. A screw (not shown) is mounted in the holes to secure the shim in position between the fingers  586  and  587  of the receiver to maintain the tabs  590  of the injector in the holes  592  of the receiver and prevent inadvertent separation of the injector from the receiver. The shim  600  is removed from between the fingers of the injector in any usual manner, e.g. by reversing the steps practiced to insert the shim between the fingers.  
      As can be appreciated, the components of non-limiting embodiments of the hinge part having the quick assembly receiver and injector can be interchanged with one another to provide additional non-limiting embodiments of the hinge part of the invention.  
      The form of the invention shown and described above represents illustrative non-limiting embodiments of the invention. It is understood that various changes may be made without departing from the teachings of the invention defined by the claimed subject matter that follows.
