Title: Method and apparatus for transparent shelves and drawers for kitchen cabinets

Description:
RELATED APPLICATIONS 
     This application is a Continuation-in-Part of U.S. patent application Ser. No. 12/288,899 filed on Oct. 25, 2008 now abandoned. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates generally to cabinets and, more particularly, is concerned with a method and apparatus for transparent rollout cabinet drawers and shelves. 
     2. Description of the Prior Art 
     Tall pantry cabinets are typically designed with fixed shelves, full width rollout shelves, and multiple foldout door panels with shelves or individual rollout shelf units with individual cabinet panel fronts. In tall pantry cabinets using the aforementioned designs, the problems normally found are as follows: With fixed or even adjustable shelves, only the items in the front of a typical 24 inch deep cabinet can be seen or accessed very easily. When full width rollout shelves are used, it is difficult to see items near the rear as labels on cans, or other food items, are typically placed on the side of the items and when stored sitting upright the label is out of view because it is blocked by the items placed directly in front. It is also difficult to reach to the back of a full width rollout drawer once the drawer or shelf heights gets above shoulder height. Multiple foldout doors with shelving attached is also used but this system seems to waste space due to the amount of space taken up by the unit itself. It also is difficult to locate items in the unit without unfolding some if not all of the doors. The individual tall pantry units are typically 6 inches to 12 inches wide with either wood, metal or wire shelving and have individual cabinet door panel fronts, base, back sides, etc. Door panel fronts and cabinet doors are customarily the most expensive part of the cabinet and also each door unit must be fully extended to see the items in the unit. To have multiple units, cost would be high due to increased door and cabinet cost, and locating items would not be as easy as the present invention, as most items cannot be seen until each door panel is rolled out fully on those individual pantry units. 
     SUMMARY OF THE PRESENT INVENTION 
     The present invention is a transparent rollout pantry system designed to work with any cabinet makers tall pantry cabinets. These pantry cabinets are also referred to in manufacturer&#39;s brochures as tall storage or utility cabinets. This system can be used with rollout shelf units, with shelving on either one or two sides of a clear supporting panel and each unit typically would be 24 inches to 80 inches tall, 6 inches to 8 inches wide and 18 inches to 24 inches deep depending on cabinet manufacturer&#39;s specifications. Typically three to four rollout shelf units with either one or two sided shelving would be used with each pantry cabinet depending on its width. Two clear pullout side by side drawers at one or more levels can be used above the rollout shelves. The present invention is designed to work with any cabinet makers typical tall pantries which are 24 inches to 36 inches wide, 18 inches to 24 inched deep and up to 96 inches high. 
     The system is a combination of vertical rollout units made using any transparent material, such as acrylic, that can be cut and fitted together and then fused to make a strong, self supporting lightweight unit. Each unit is then supported with two heavy duty drawer guides placed at the base or top to carry vertical loads and at least one horizontal heavy duty guide at the opposite end to laterally stabilize the unit. Conventional drawer guides are used, and any conventional guide could be used that will carry the required load. By having a transparent unit and shelves only wide enough to typically support most pantry items, items stored are only one deep and can be easily seen without even rolling out a unit, and then can be easily reached by pulling out the appropriate unit containing the desired item. Clear rollout drawers are also part of the system and would be used in pairs above the rollout units. Drawers are used above rollout units in pairs as they have the advantage, by being clear, of seeing items through the bottom of the drawer, and by having the drawers in pairs, someone can extend one drawer at a time and reach to the back of each drawer from the sides, and this gives more drawer usage than full width conventional shelves. As mentioned earlier, full width rollout drawers above shoulder height make it difficult to access items at the rear of the drawer. 
     The foregoing and other objects and advantages will appear from the description to follow. In the description reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced. These embodiments will be described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that structural changes may be made without departing from the scope of the invention. In the accompanying drawings, like reference characters designate the same or similar parts throughout the several views. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is best defined by the appended claims.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The following discussion describes in detail at least one embodiment of the present invention. This discussion should not be construed, however, as limiting the present invention to the particular embodiments described herein since practitioners skilled in the art will recognize numerous other embodiments as well. For a definition of a complete scope of the invention the reader is directed to the appended claims.  FIGS. 1 through 9  illustrate the present invention wherein a method and apparatus for a system of rollout shelves and drawers for a kitchen pantry cabinet is disclosed. 
     Turning to  FIG. 1A , therein is shown the present invention  10  comprising a conventional kitchen pantry cabinet  12  having front side doors  14  with hinges  70  thereon (while only one right door is shown in this view for visual clarity, typically the cabinet would have a left and right door thereon). The present invention  10  comprises a system of rollout shelf units  16  (sometimes referred to herein as rollout units, rollout units of shelves, storage units, or rollout shelf units), and drawers  18  for a kitchen pantry cabinet  12  having doors  14  thereon comprising at least two rollout shelf units  16  as shown in  FIGS. 2-5  and at least one pair of left and right hand drawer units  18  as shown in  FIGS. 6-8 . Each shelf unit  16  will contain at least one individual shelf  30  and may contain as many as four or more individual shelves as shown in  FIG. 1A . All pieces of the rollout shelf units  16  and the drawers  18  are cut from clear planer acrylic  19  or other similar transparent material that can be fused together to make the structural connections between the pieces. Any method of fusing or solvent welding the pieces together would be acceptable so long as the joint was effectively strong such as would occur when solvent welding PVC pipe together using one or two part PVC cement or acrylic cement or the like. The lightweight clear material  19  used in the present invention  10  will not exceed ¼ inch in thickness and the strength of the units will be attained by fusing the pieces at carefully selected locations to form certain structural shapes, e.g, “L”, “C” and “I”, to increase the bending, shear and buckling loads of any of the individual pieces. Each rollout shelf unit  16  will not exceed 80 inches in height, 8 inches in width and 24 inches in depth so as not to exceed the load carrying capacity of the unit or heavy duty drawer guides  36  when loaded with items that typically are stored in kitchen pantry cabinets. Also shown are left  15  and right  17  of the outside drawers  16  and left  21  and right  23  of the inside drawers  16  along with an upper horizontal guide  46  and handle  48  on the outside surface of shelf unit  16  and drawer  18 . Also shown are drawer guides  58  for drawers  16 , support or strut  44 , center support or strut  64 , vertical support or strut  66 , and strut  68  on the inside of the side wall of the cabinet  12 . Also shown are the side support members  20 , center support members  22 , stiffener members  32  and lower stiffener members  34 . Also shown are a few exemplary food items  72  being stored inside the drawers  18  and shelves  16 . 
       FIG. 1B  is similar to  FIG. 1A  but shows additional details including block  40 , horizontal guide  46  on top of each drawer  18 , cabinet side  60 , top  61 , back  62 , interior bottom  42  and the bottom  43  of the exterior of cabinet  12  which would be in contact with the supporting surface such as a floor of a building. Also shown are supports or struts  44 ,  64 ,  66  and  68  on the inside of the walls of cabinet  12 . Drawers  18  are shown in phantom. All references to the left/right sides and other sides of the cabinet  12 , drawers  18 , shelves  16  and/or other portions of the present invention  10  herein would correspond to those referenced in  FIGS. 1A and 1B . 
     Turning to  FIGS. 2-3  therein is shown a shelf  16  having a solid side support panel or member  20  of a typical outside unit  16  of the system (while only a right side shelf is shown, there would also typically be a left side shelf as shown in  FIG. 1A ). Left  15  and right  17  outside units are shown in  FIG. 1A  being on the outside of the two inner or inside units one each being on the left  21  and right  23 .  FIGS. 4-5  illustrate a solid center support panel or member  22  for the inside unit  16  being one on the left  21  and right  23  as shown in  FIG. 1A . 
       FIG. 3A  shows a first stiffener  32  and an individual shelf floor  30  being fused or having a solvent welded joint at  31 .  FIG. 3B  shows a second lower deep stiffener  34  attached to inner surface of the front  26  and rear  24  shelf support and edge of the floor of a shelf.  FIG. 3C  shows substantially a “C” Channel formed by the fusion of side support member  20 , front panel  26  and back panel  24 . 
     Turning to  FIGS. 2-5  therein is shown the back shelf support panel  24 , the front shelf support panel  26 , the top support panel  28  on which the stabilizing drawer guide  46  is mounted, a typical floor of an individual shelf  30 , a stiffener piece  32  for the edge of the shelf which when fused makes a composite “L” angle shaped beam (see  FIG. 3A ) that materially strengthens the system, including but not limited to, the individual shelves  30  and main support members  20 ,  22 , and also serves as a stop to keep items from falling off the shelf if someone rolls the shelf in a reckless manner. Calculations indicate that an un-stiffened individual shelf  30  would have to be approximately ½ inch thick in order to have the same strength, i.e., deflection, as an individual shelf designed according to the teachings of the present invention  10  and would weight approximately 1.87 times more per unit of individual shelf which evidences the advantages of the present invention. Also shown is a lower deep stiffener member  34  that when fused to the bottom outside edge of the floor of a shelf and the inner surfaces of the front and back pieces (see  FIG. 3B ) make a strong composite section that is used to mount drawer guides  36  to the unit. Typically, two conventional supporting heavy duty drawer guides  36  on each side of a unit carry the vertical load of the unit. Also shown is fastener  38  that fastens the solid block  40  which can be wood, metal or the like, and which runs the length of the cabinets, and, supports portions of the drawer guides  36  for a shelf unit and which block is attached to the cabinet bottom or floor  42  on the interior of the cabinet  12  (not shown see  FIG. 1B ). Strut  44  or cross member is used to fasten the horizontal drawer guide  46  thereto which guide is then fastened to the top of the rollout shelf unit  16  which helps stabilize them in the vertical plane. A conventional handle  48  is also shown. 
       FIG. 5A  shows substantially an “I” beam-like channel formed by the fusion of front panel  26 , center support member  22  and back panel  24 . 
       FIG. 5B  shows an exemplary installation and an exemplary conventional drawer guide  36 ,  58  having inner  80  and outer  82  housings or portions, upper and lower ball bearings  84 , wherein each portion uses a fastener  88  for attachment to a block  40  and stiffener  34  as, e.g., would be seen in  FIG. 5 . 
     Turning to  FIGS. 6 ,  7  and  8  therein is shown a right-hand side clear, rollout drawer  18 . A left side drawer  18  would essentially be a mirror image of the drawer  18  shown in  FIGS. 6 ,  7  and  8 . Shown is a conventional pull handle  48 , a clear drawer bottom  50  that is easy to see through and can be cut and fused together to make a strong lightweight drawer unit, the clear drawer front  52 , the clear drawer sides  54  and the clear drawer back  56 , and the drawer guides  58  (guides  36  and  58  may be the same or different type of guide). Also shown is the side  60  of the cabinet which will support the drawer on one side. The back  62  of the cabinet will support the center support strut member or piece  64  for the left and right hand drawers  18 . Also shown is a vertical support  66  at the front edge of the cabinet that supports the front end of member  64 . Also shown is a spacer support strut  68  attached to the side  60  of the cabinet. The support pieces  64 ,  66 ,  68  and  44  (not shown, see  FIG. 1A ) are expected to be made of metal, wood or acrylic or similar material. Various combinations of the rollout shelf units  16  can be used with different pantry cabinets  12  (not shown, see  FIG. 1A ) depending on the width of the cabinet, and whether the doors  14  open fully to let items be accessed from both sides of a center supported rollout shelf unit, such as shown as item  22  in  FIGS. 4 and 5 . This type rollout shelf unit  16  is used for all intermediate units of the system and can be used for the outside rollout shelf units of the system if the doors  14  (not shown, see  FIG. 1A ) open fully. However, some pantry cabinets  12  use concealed hinges that let doors  14  open to just over ninety degrees and this type pantry cabinet would be better served using the side supported rollout shelf units as shown as item  20  in  FIGS. 2 and 3 , as items would be hard to access from the outside due to the doors if the rollout shelf unit of  FIGS. 4 and 5  were used. This system of rollout shelf units  16  and pairs of drawers  18  maximize the storage capacity of the pantry cabinet  12  and let all items in the cabinet be seen and accessed easily. 
     Turning to  FIGS. 9A-9C , therein are shown the results of load testing of three identical, typical acrylic columns/beams as used and taught by the present invention, e.g., item  20 ,  22  in  FIGS. 3 and 5 . Each of the three columns shown in  FIG. 9A-9C  are 5.0 inch wide (shown as W), 0.20 inches thick (shown as T) and 52 inches long (shown as L). (The present invention teaches that its lightweight Plexiglas or acrylic column structural members, e.g., item  20 ,  22  in  FIGS. 3 and 5 , are defined as being less than or equal to 0.25 inches). The lower end of each column was placed on a support surface  74  and the buckling, if any, due to the load applied on the upper end of the column could be observed at  76 . The buckling was visually observed for three different loads placed on the upper end of the columns and with side supports  78  being applied as indicated. Three different loads 5 lbs. (shown as F 1  on  FIG. 9A ), 15 lbs. (shown as F 2  on  FIG. 9B ) and 70 lbs. (shown as F 3  on  FIG. 9C ) were applied. The side supports  78  are equivalent to support that the shelf floors  30  (See  FIG. 3 ) would provide as taught by the present invention. In summary, the test results indicate that the columns buckled when the spans were long when compared to the thickness as seen in  FIGS. 9A and 9B ; however, the columns did not buckle when the spans were short when compared to the thickness as seen in  FIG. 9C  which is taught by the present invention  10  as shown in  FIGS. 3 and 5 . 
     The following additional detailed explanation is offered of the present invention  10  and may make reference to each of the  FIGS. 1-9 . The present invention  10  comprises: A) A rollout system of two types of pantry units of a clear light weight material  19 , such as acrylic, that can be cut and fused together to make at least two rollout shelf units  16  that can be used with at least one pair of drawers  18  above and one of the rollout units being comprised of a front  26  and back  24  support piece of substantially the same height and width and a solid center support panel  22  which is a solid center support panel of substantially the same height as the front and back pieces minus two times the thickness of the material so that when the solid center support panel is fused to the front and back pieces the solid center support panel will be one material thickness below the top of the front and back pieces to allow the top and bottom pieces to fit flush with the top and bottom of the front and back pieces and after fusing the solid center support panel  22  to the front and back pieces this will form an I shaped column as viewed from the top and this column shaped piece will have a top piece  28  and a bottom piece  30  that will be substantially the same length as the horizontal dimension of the solid center support panel, and the top piece which will be fused to the front back and solid center support panel will be the same width as the front and back pieces and the bottom piece which will be fused to the front back and solid center support panel, will be the same width as the front and back pieces minus two times the thickness of the material used so that the two deep stiffener pieces  34  which will be substantially the same length as the bottom piece, and the width of the deep stiffener pieces will be the width of the heavy duty drawer guide  36  plus the width of the stiffener pieces, and the deep stiffener pieces planar sides are placed parallel to the solid center support panel, and the deep stiffener pieces are fused to the longitudinal edges of the bottom piece and to the front and back pieces, so that the deep stiffener pieces extend below the bottom of the bottom pieces by the width of the heavy duty drawer guides, and above the bottom of the bottom piece the same height as the stiffener pieces extend above the bottom of the intermediate shelves, and there will be at least one intermediate shelf on each side of the solid support center panel and the intermediate shelves will be substantially the same length as the top and bottom pieces and the sum of the widths of the intermediate shelves on each side of the solid support center panel plus three material thicknesses is substantially equal to the width of the front and back pieces, so that the stiffener pieces outside planar face is substantially flush with the vertical edges of the front and back pieces, and the intermediate shelves are fused to the solid center support panel, the front and back pieces and to the stiffener pieces, whose length is substantially the same length as the intermediate shelves, and the stiffener pieces lower edge will be flush with the bottom of the intermediate shelves and have enough height to act as a stop to keep items placed on the shelves from falling off the shelves when the rollout unit is extended or retracted, and will also be high enough to that when fused to the intermediate shelf it will form a L shaped structural section  32  and develop enough shear at the joint to make the composite shape carry more bending moments than either the flat shelf by itself or the stiffener by itself and since the intermediate shelf and stiffener are fused to the solid support panel and the front and back pieces, these intermediate shelves stiffen the solid support panel and the front and back pieces the same as a web stiffener on a steel column, to eliminate buckling of these pieces, which allows the rollout unit to carry more load than it would carry if it was not fused, as pieces of this thickness of acrylic are too thin for being joined by screws or bolts and thus are hard to join and develop the shear across the joints by other methods, such as screws or bolting, which will be used only to fasten the heavy duty drawer guides, whose flat sides are parallel and fit flat against the inside planer sides of the deep stiffener pieces, and there will be at least two binding posts with slotted screws sized to fit the heavy duty drawer guides, and the binding posts and screws will attach the extendable piece of the heavy duty drawer guides to the deep stiffener pieces and the fixed piece of the heavy duty drawer guides will be fastened to a wood or metal block or base  40  piece that is substantially the same length as the top and bottom piece, the same width as the bottom piece minus the thicknesses of the two heavy duty drawer guides, and the base piece thickness is substantially the same as the width of the heavy duty drawer guides, and the base piece is fastened to the cabinet floor or cabinet shelf with at least two bolts at front of back or screws  38  or the like that are countersunk flush with the top of the base piece and the bottom edge of the heavy duty drawer guides bear on the cabinet floor  42  or cabinet shelf, and the fixed piece of the heavy duty drawer guides are screwed or bolted to the base piece with at least two fasteners or the like, and the rollout unit deep stiffener pieces, when bolted to the heavy duty drawer guides will clear the cabinet floor or cabinet shelf with enough margin to not touch the cabinet floor panel, and the bottom of the bottom piece of the rollout unit will clear the top of the base piece when the rollout unit is extended or retracted, and there is a horizontal heavy duty drawer guide  46  fastened longitudinally to the top of the top piece  28  of the rollout unit  16  to laterally stabilize the rollout unit, and the heavy duty drawer guide has its flat extendable side against the top of the top piece so that it can be fastened to the top piece with bolts, and the fixed side of the heavy duty drawer guide will be fastened to two wood, metal or acrylic struts  44  that are near the front and back of the cabinet, and these struts fasten to the sides  60  of the pantry cabinet  12  to support the heavy duty drawer guide, and the rollout unit has a cabinet knob or pull handle  48  fastened to the front piece  26  of the rollout unit at a convenient height to pull the rollout unit out to an extended position, and this rollout unit when complete is designed to carry items that are placed on shelves only one deep on each side of a solid support panel with the ability to see and easily access any item when the rollout unit is extended. B) There is a second type rollout unit which could be used when the kitchen pantry cabinet doors cannot be opened fully to let items on the first type rollout unit be accessed easily, and this rollout unit has a front and back piece of substantially the same height and width and a solid side support panel  20  that connects between the front  26  and back  24  pieces at the edge being fused one material thickness below the top of the front and back pieces at the top, and extending below the bottom of the front and back pieces by the width of the heavy duty drawer guide, and when fused together these three pieces form a structural column “C” channel shape viewed from the top and there is a top piece and a bottom piece of substantially the same length, and both the front piece and the back piece are slightly shorter than the vertical dimension of the solid side support panel, and the top piece is the same width as the front and back pieces, and is fused to the front back and solid side support panel at the joining edges, and the bottom piece is the width of the front and back pieces minus two times the thickness of the material used, and the bottom of the bottom piece is flush with the bottom of the front and back pieces, and the bottom piece is fused to the front back and solid side support panel, and there is a deep stiffener piece substantially the same length as the bottom piece, whose planar side is parallel to the solid side panel and extends below the bottom of the bottom piece the width of the heavy duty drawer guide, and above the bottom of the bottom piece the same height as the stiffener piece extends above the bottom of the intermediate shelves, and the deep stiffener piece is fused to the edge of the bottom piece and to the front and back pieces, and there will be at least one intermediate shelf that is substantially the same length and width as the bottom piece, and the intermediate shelf is fused to the front, back and solid side support panel, and to a stiffener piece at the outside edge of the intermediate shelf, whose length is the same as the length of the intermediate shelf and whose planar side is parallel to the solid side support panel, and the bottom edge of the stiffener piece is flush with the bottom of the intermediate shelf, and has a minimum height above the shelf to act as a stop to keep items that are placed on the shelf from falling off the shelf when this rollout unit is extended or retracted, and this stiffener will also be high enough, so that when fused to the intermediate shelf it will form an L shaped piece  32  that structurally will carry more bending moment than either the flat shelf by itself, or the stiffener by itself, and the intermediate shelf and stiffener by being fused to the solid side support panel and back and front pieces, stiffen the solid side support panel and back and front pieces the same as web stiffeners on a steel column, to eliminate buckling of these pieces, which allows the rollout unit to carry more load than it would carry if it was not fused, as pieces of this thickness and this type material would be difficult to join and develop the shear across the joint by other methods such as bolting, which will be used only to fasten the heavy duty drawer guides, and one guide is fastened to the inside of the deep lower stiffener piece  34 , and the deep stiffener piece is at the open side of the rollout unit and the other heavy duty drawer guide is fastened to the inside lower portion of the solid side support panel, which is extended below the bottom of the bottom piece, by the width of the heavy duty drawer guide, and acts the same as the other deep stiffener piece, to which the extendable piece of the heavy duty drawer guide is bolted and the solid support panel and the deep stiffener piece are bolted to the heavy duty drawer guides with at least two binding posts with slotted screws or the like sized to fit the heavy duty drawer guides, and the fixed piece of the heavy duty drawer guides are fastened to a wood or metal base piece  40  that is substantially the same length as the bottom piece, the same width as the bottom piece minus the thickness of two heavy duty drawer guides, and the base piece extends up above the cabinet floor or a cabinet shelf with enough height to substantially fasten the fixed side of the heavy duty drawer guides, and the base piece will be fastened to the cabinet floor or to a cabinet shelf with at least two bolts or screws or like fasteners  38  that are countersunk flush with the top of the base piece, and the bottom edge of the heavy duty drawer guides bear on the cabinet floor  42  or a cabinet shelf and the fixed piece of the heavy duty drawer guides are screwed or bolted to the base piece with at least two fasteners, and the rollout unit deep stiffener pieces when bolted to the heavy duty drawer guides will clear the cabinet floor or cabinet shelf with enough margin to not touch the cabinet floor or cabinet shelf, and the bottom piece of the rollout unit will clear the top of the base piece when the unit is extended or retracted, and there is a heavy duty drawer guide fastened longitudinally to the top of the top piece of the rollout unit to laterally stabilize the rollout unit, and the heavy duty drawer guide has its flat extendable side against the top of the top piece so that it can be fastened to the top piece with bolts, and the fixed side of the heavy duty drawer guide will be fastened to two wood, metal or acrylic struts that are near the front and back of the cabinet, and these struts fasten to the sides of the pantry cabinet to support the heavy duty drawer guides, and the rollout unit has a cabinet knob or pull handle fastened to the front piece of the rollout unit at a convenient height to pull the rollout unit out to an extended position. C) There will be at least one pair of side by side drawers  18  made from the same material as the rollout units and each drawer will have a front  52  piece and back  56  piece of substantially the same length and two side pieces of substantially the same length, and the front, back and side  54  pieces will be fused together with floor  50  and these four pieces of the drawer will be substantially the same height, and will be high enough to attach the heavy duty drawer guides  58 , and structurally carry the loads placed in the drawer bottom when it is fused inside the box structure with its bottom flush with the bottom edge of the vertical pieces formed by the front, back and two side pieces, and the length of the drawer bottom and side pieces will substantially be equal to the length of the top piece  28  of the rollout unit, and the drawer front and back pieces will be of such length that the sum of their lengths plus the thickness of two heavy duty drawer guides plus a central support strut  64  that supports the two inside heavy duty drawer guides will be equal to the distance between the outermost edges of the two outside rollout units that will be located below, and the central support piece will be sized as small as possible in width to support the heavy duty drawer guides structurally, so as to maximize the drawer widths, and this central support strut will attach to a vertical strut  66  at the front of the cabinet  12  that attaches to the top  61  of the pantry cabinet, and to the front horizontal strut  44 , that is supporting the top heavy duty drawer guides  46  of the rollout shelf units  16 , and this central support strut also attaches to the back  62  of the pantry cabinet, and the outside of the left hand and right hand pair of drawers have a heavy duty drawer guide that is fastened to a wood strut  68 , that is fastened to the side  60  of the pantry cabinet, and this strut extends from front to back of the rollout units, and the strut is substantially the same height as the width of the heavy duty drawer guides, and the thickness of this strut plus the thickness of the heavy duty drawer guide is substantially equal to the distance between the side wall of the pantry cabinet and the outside edge of the outermost rollout unit on the same side of the cabinet, and the extendable side of the heavy duty drawer guides attach to the drawer sides with binding posts and slotted screws or the like, and the fixed side of the heavy duty drawer guides fasten to the struts with bolts or screws or the like, and there will be a cabinet knob or pull handle  48  on the front of each drawer to move the drawer to an extended or retracted position. 
     As previously stated concerning the expected material of construction of the present invention  10 , all pieces of the rollout shelf units  16  and the drawers  18  are cut from clear planer acrylic  19  or other similar transparent material that can be fused together to make the structural connections between the pieces. The material referred to herein as acrylic is polymethyl methacrylate (PMMA) which is a transparent thermoplastic, often used as a light or shatter-resistant alternative to glass. It is sometimes called acrylic glass. Chemically, it is the synthetic polymer of methyl methacrylate. PLEXIGLAS, POLYCAST, and LUCITE are brands of high grade acrylic. Acrylic is colorless and highly transparent, the solid material has high dimensional stability and good resistance to weathering and shock. It is used in aircraft canopies and windows, in boat windshields, and as a general alternative to glass in many applications. An object made of acrylic has the unusual property of keeping a beam of light reflected within its surfaces and thus carrying the beam around bends and corners. It is known that acrylic has a flexural strength of approximately 15,000 psi; therefore the flexural loads or stresses relative to the present invention are expected to be kept under 1,500 psi which is a safety factor of 10:1 so as to prevent creep and to limit long term deflection.
