3 Field o~ the Invention
4 This invention relates generally to a drawer cabinet kit S constructed of plastic structural panels. More specifically, 6 the present invention relates to a stackable modular cabinet 7 constructed of injection molded plastic panels to contain at 8 least one removable drawer, and which is capable of being 9 packaged and shipped in a knocked-down state and constructed into a secure drawer cabinet at a desired site.
I2 Background Information 13 Throughout the home, a need exists to store a large 14 variety of different items. This is particularly true of IS garage and utility areas where a vast array of products are 16 generally stored for selected use. The accumulation of these 17 various objects and products gives rise to a need for 18 adequate storage of those items when not in use.
19 ~larious cabinets for storing items such as gardening tools, automotive supplies, household items and the like are 21 well known. One of the more popular type of cabinets for 22 storing household items is a cabinet with a plurality of 23 pull-out drawers. Cabinets of this type are generally 24 shipped to a consumer or a supplier fully assembled.
Atty: Mcflale & Slavin, f.A.
Atty_ Docket No. 1251.320 I
1 Shipping fully assembled cabinetry requires a considerable 2 amount of space available within a shipping medium. Because 3 space is limited, the cost associated with shipping assembled 4 cabinets is comparatively high.
Alternatively, drawer cabinet assemblies are custc:~mized 6 for the consumer based on the consumer's needs_ With 7 customized cabinets, the consumer selects the cabinet 8 material, the size of the associated drawers, and the drawer 9 guides needed to guide the drawers in and out of the cabinet.
Numerous devices have been utilized throughout history to 1I guide drawers in and out of drawer cabinets. The simplest 12 mechanism is a box into which the drawer slides. Other 13 methods of control include runners on either side of the 14 drawer or a single runner under the bottom of the drawer with notches to hold the drawer in alignment with the cabinet.
16 All of these basic guide systems have high levels of friction 17 between the drawer and the cabinet and, consequently, rapidly 18 wear out. Numerous low friction devices have been designed to 19 facilitate movement of drawers in and out of cabinets including ball bearings, wheels, and sliders. Most of these 21 low friction devices require unsightly tracks along the side 22 of the drawers, and wide spaces between the sides of the 23 drawers ,and the drawer face to allow passage of the low Atty: McHale & Slavin, P.A.
Atty. Docket No. 1251.320 2 1 friction devices from the inside of the drawer cabin et to the 2 outside when th a drawer is extended.
3 Side play of the drawer when extended is another 4 difficult problem, particularly in the basic forms of drawer S guides. Often the drawer must be movedfrom side to side and 6 up and own in order to get it to return to the drawer d 7 cabinet. As the guides become worn, e problem becomes th even 8 more severe. Even drawer slues um11~1y 1.V11C1J, lJrzli 9 bearings and sliders have binding problems, especially when the drawers are heavily loaded or the slide parts have become 11 slightly worn.
12 'fhe ball bearing type of drawer slide creates a 13 different problem. Because there is vzrrually r» 5~u~ ~Iay 14 in a ball bearing slide, the drawer cabinet must be perfectly IS aligned with the drawer slide in order to eliminate binding 16 as the drawer is moved in and out. Skilled labor and time 17 are required to properly position a ball bearing slide.
18 Fabrication costs of low friction slide arrangements are 19 another problem. The slide arrangements must be specially made for each different length of drawer. A long drawer 21 requires a long slide arrangement and a short drawer requires 22 a short slide arrangement. Manufacturers are required to 23 maintain, supplies of many different lengths of drawer slides 24 or modify slides for each customer.
Atty: McI-talc & Slavin. P.A.
Atty. Docket No. 1251.320 3 1 full extension drawer slides are a variation of the 2 typical drawer slide and are used to permit full extension of 3 drawers, such that the back of the drawer is fully 4 accessible. Such drawer guides usually use three or more rails with one rail (cabinet rail) being attached t~:~ the 6 cabinet, one rail (drawer rail) being attached to the drawer 7 and one rail (floating rail) gliding between the drawer and 8 cabinet rails. Examples of such drawer guides are disclosed 9 in United States Pat. Nos. to Card, 1,537,067, Tobey, 2,099,148, Schaffert, 1,129,831, Bullock et al, 3,203,749, 11 Vander hey, 4,004,841, Lautenschalager 5,733,027, Fleisch, 12 5,895,102, Fraccaro, 6,390,574. In these systems, rollers or 13 ball bearings are provided on racks between the floating rail 14 and the cabinet and drawer rails to provide free gliding movement between each of the rails.
16 One of the problems associated with such systems is that 17 they tend to be rather large and bulky, which limits their 18 use on smaller drawers. Further, such systems are relatively 19 complicated and difficult to fabricate, resulting in high costs to consumers.
21 Such prior art systems have not met all of the needs of 22 manufacturers to provide a product that can be easily 23 manufactured, packaged and shipped, or the needs of consumers 24 requiring economical and versatile do-it-yourself storage Atty: McHale & Slavic, P.A.
Atty. Docket No. L 251.320 4 1 kits. Moreover, because the prior art devices do not break 2 down they are difficult and expensive to ship from the 3 manufacturer to the consumer.
4 Paramount among such needs is an easy to assemble kit which can be easily assembled by an average homeowner.
6 Structure is a further consideration; a cabinet formed from 7 separate panels must create cabinet walls which resist panel 8 separation, buckling and racking in such a way as to unify 9 the entire enclosure.
I0 Also, from a versatility standpoint, a cocperating 11 drawer and guide should be present which can be easily 12 assembled oz modified after assembly of the side, top, base 13 and back panels, and which provides security and dependable I4 access to the contents of the drawers without the complex and IS difficult to assemble mechanisms associated with the prior I6 art .
17 There are also commercial considerations that must be I8 satisfied by any viable drawer cabinet system or kit;
19 considerations which are not entirely satisfied by state of 20 the art products. The drawer cabinet must be formed of 2I relatively few component parts that are inexpensive to 22 manufacture by conventional techniques. The drawer cabinet 23 must also be capable of being packaged and shipped in a 24 knocked-down state.
Atty: McHale & Slavin, P.A.
Atty. Docket No. 1251.320 5 i In addition, there are ergonomic needs that a drawer 2 cabinet system must satisfy in order to achieve acceptance by 3 the end user. The system must be easily and quv~ckly 4 assembled using minimal hardware and requiring a minimal number_ of tools. further, the system must not re~:~uire 6 excessive strength to assemble or include heavy component 7 parts. Moreover, the system must assemble together in such a $ way so as not to detract from the internal storage volume of 9 the resulting wall cabinet or otherwise negatively affect the utility of the drawer cabinet.

Atty. Docket No. 1251.320 I Brief Description of the Invention 2 The present invention provides an assembly, or kit, of 3 injection molded panels having integrated connectors which 4 combine to form a drawer cabinet with integrally formed guide rails and cooperating pull out drawers supported upon a 6 plurality of rollers. The cabinet panels are formed of 7 injection molded plastic and include integrally formed 8 connectors to interlock with one another without the need for 9 separate fasteners. The integrated connection of the side, IO back, top and base panels simplifies the drawer cabinet Il construction and minimizes the number of components required 12 to assemble'the drawer cabinet. Injection molding allows the 13 panels to be formed with integral cross-bracing, ribs and 14 gussets for increased rigidity. When supplied as a kit, IS assembly of the drawer cabinet requires minimal hardware and I6 a minimum number of hand tools.
I7 The drawer cabinet assembly includes a base panel, left I8 and right side panels and a top panel. The base panel is I9 constructed with integrally formed outwardly extending 20 contoured locking posts for interlocking cooperative 21 engagement with sockets formed into the bottom surfaces of 22 the left and right panels. The engagement between the 23 locking posts and the sockets serve to rigidly connect the 24 components together, preventing the panels from bowing Atty: McHale & Slavin, P.A.
Atty. Docket No. 1251.320 1 inwardly or outwardly under loads to provide a structurally 2 sound cabinet with a pleasing aesthetic appearance. The 3 construction of the panels minimize complexity of completing 4 the assembly while increasing versatility by allowing the consumer to customize the assembly for specific needs. For 6 example, the bottom surface of the base panel includes 7 sockets allowing the base panel to be used as a top panel.
8 This construction permits the multiple drawer cabinet units 9 to integrated into a multiple drawer cabinet. Alternatively, the drawer cabinets may be placed in a stacked arrangement 11 having the lower surface of one drawer cabinet removeably 12 engaged with the upper surface of another top panel of an 13 adjacently positioned drawer cabinet.
14 The interior portion of the cabinet includes integrally molded horizontal channels extending along each side. The 16 channels extend from the front portion of each side panel to 17 the rear portion of each side panel. Each channel is 18 constructed and arranged to accept an outwardly depending 19 drawer guide rail in a cooperating arrangement to prevent drawer tipping during extension and insertion ther_eof_ The 21 base panel includes a plurality of rollers secured within the 22 base panel in a manner to cooperate with the bottom surface 23 of the drawer member, allowing the drawer to be easily moved 24 when loaded. In a preferred embodiment, a first pair of Atty: McHale & Slavin, P..A.
Atty. Docket No. 1251.320 1 rollers are positioned to support the front portion of_ the 2 drawer member and a second pair of rollers are positioned to 3 support the rear portion of the drawer.
4 The snap together construction minimizes complexity of completing the assembly while increasing versatility by 6 allowing the consumer to customize the assembly for specific 7 needs. The built-in construction of the drawer guide 8 channels and rollers eliminates the need for skilled 9 tradesmen to line-up and mount complicated hardware within the cabinet. In this manner, the consumer can select one or 11 a plurality of drawer cabinets having various heights, snap 12 together the panels in the desired configuration, and 13 thereafter slide in the drawers to complete the assembly.
14 The drawers are pre-constructed of polymeric material and include a pair of integrally formed handles that allow a 16 removed drawer to be easily transported.' The bottom surface 17 of the drawer members are adapted to cooperate with the 18 rollers for easy movement in and out of the cabinet even when 19 heavily loaded. In addition, the bottom surface of the drawer member includes an alignment pocket adapted to 21 cooperate with the upper surface of the top panel of the 22 cabinet for removeably fixed placement outside of the 23 cabinet., Arty: McHale & Slavin, P.A.
Atty. Docket No. 1251.320 9 1 In operation, as a loaded drawer is pulled outward it 2 rolls freely on the rollers, utilizing the track and channel 3 combination prevent the drawer from tipping. This 4 construction allocns the drawers to be easily opened with heavy loads without requiring complex sliding track 6 mechanisms to prevent tipping of the drawer.
7 Accordingly, it is an objective of the present invention 8 to provide a polymeric drawer cabinet assembly having 9 integrally formed guide assemblies and at least one cooperating drawer.
I1 It is a further objective of the present invention to 12 provide a drawer cabinet assembly having an integrally formed 13 drawer guide, by which a cooperating drawer can be smoothly 14 guided inwardly and outwardly of a cabinet body without the need for complex metal guiding mechanisms.
16 Yet a further obj ective of the present invention is to 17 provide a drawer cabinet assembly having an integrally formed 18 drawer guide which allows the drawer to be guided a 19 sufficient distance out of the cabinet body to provide access to the interior of the drawer without tipping.
21 Still yet a further objective of the present invention 22 is to provide a drawer cabinet assembly constructed from 23 injection molded plastic panels having integrated connectors 24 for increased structural integrity and easy assembly.
Atty: McHale & Slavin, P.A.
Atty. Docket No. 12S 1.320 10 o 1 Another objective of the present invention is to provide 2 a drawer cabinet storage kit in which the side walls, top 3 panel, and base panel are interlocked without the neer for 4 separate fasteners.
Yet another objective of the present invention i:~ to 6 provide a kit for a drawer cabinet that is capable of being 7 packaged and shipped in a knocked-down state and constructed 8 into a secure drawer cabinet.
9 Still yet another objective of the present inventicn is to provide a drawer and guide assembly which allows an end 11 user to customize a drawer cabinet to suit an individual 12 application.

I2 Background Information 13 Throughout the home, a need exists to store a large 14 variety of different items. This is particularly true of IS garage and utility areas where a vast array of products are 16 generally stored for selected use. The accumulation of these 17 various objects and products gives rise to a need for 18 adequate storage of those items when not in use.
19 ~larious cabinets for storing items such as gardening tools, automotive supplies, household items and the like are 21 well known. One of the more popular type of cabinets for 22 storing household items is a cabinet with a plurality of 23 pull-out drawers. Cabinets of this type are generally 24 shipped to a consumer or a supplier fully assembled.
Atty: Mcflale & Slavin, f.A.
Atty_ Docket No. 1251.320 I
1 Shipping fully assembled cabinetry requires a considerable 2 amount of space available within a shipping medium. Because 3 space is limited, the cost associated with shipping assembled 4 cabinets is comparatively high.
Alternatively, drawer cabinet assemblies are custc:~mized 6 for the consumer based on the consumer's needs_ With 7 customized cabinets, the consumer selects the cabinet 8 material, the size of the associated drawers, and the drawer 9 guides needed to guide the drawers in and out of the cabinet.
Numerous devices have been utilized throughout history to 1I guide drawers in and out of drawer cabinets. The simplest 12 mechanism is a box into which the drawer slides. Other 13 methods of control include runners on either side of the 14 drawer or a single runner under the bottom of the drawer with notches to hold the drawer in alignment with the cabinet.
16 All of these basic guide systems have high levels of friction 17 between the drawer and the cabinet and, consequently, rapidly 18 wear out. Numerous low friction devices have been designed to 19 facilitate movement of drawers in and out of cabinets including ball bearings, wheels, and sliders. Most of these 21 low friction devices require unsightly tracks along the side 22 of the drawers, and wide spaces between the sides of the 23 drawers ,and the drawer face to allow passage of the low Atty: McHale & Slavin, P.A.
Atty. Docket No. 1251.320 2 1 friction devices from the inside of the drawer cabin et to the 2 outside when th a drawer is extended.
3 Side play of the drawer when extended is another 4 difficult problem, particularly in the basic forms of drawer S guides. Often the drawer must be movedfrom side to side and 6 up and own in order to get it to return to the drawer d 7 cabinet. As the guides become worn, e problem becomes th even 8 more severe. Even drawer slues um11~1y 1.V11C1J, lJrzli 9 bearings and sliders have binding problems, especially when the drawers are heavily loaded or the slide parts have become 11 slightly worn.
12 'fhe ball bearing type of drawer slide creates a 13 different problem. Because there is vzrrually r» 5~u~ ~Iay 14 in a ball bearing slide, the drawer cabinet must be perfectly IS aligned with the drawer slide in order to eliminate binding 16 as the drawer is moved in and out. Skilled labor and time 17 are required to properly position a ball bearing slide.
18 Fabrication costs of low friction slide arrangements are 19 another problem. The slide arrangements must be specially made for each different length of drawer. A long drawer 21 requires a long slide arrangement and a short drawer requires 22 a short slide arrangement. Manufacturers are required to 23 maintain, supplies of many different lengths of drawer slides 24 or modify slides for each customer.
Atty: McI-talc & Slavin. P.A.
Atty. Docket No. 1251.320 3 1 full extension drawer slides are a variation of the 2 typical drawer slide and are used to permit full extension of 3 drawers, such that the back of the drawer is fully 4 accessible. Such drawer guides usually use three or more rails with one rail (cabinet rail) being attached t~:~ the 6 cabinet, one rail (drawer rail) being attached to the drawer 7 and one rail (floating rail) gliding between the drawer and 8 cabinet rails. Examples of such drawer guides are disclosed 9 in United States Pat. Nos. to Card, 1,537,067, Tobey, 2,099,148, Schaffert, 1,129,831, Bullock et al, 3,203,749, 11 Vander hey, 4,004,841, Lautenschalager 5,733,027, Fleisch, 12 5,895,102, Fraccaro, 6,390,574. In these systems, rollers or 13 ball bearings are provided on racks between the floating rail 14 and the cabinet and drawer rails to provide free gliding movement between each of the rails.
16 One of the problems associated with such systems is that 17 they tend to be rather large and bulky, which limits their 18 use on smaller drawers. Further, such systems are relatively 19 complicated and difficult to fabricate, resulting in high costs to consumers.
21 Such prior art systems have not met all of the needs of 22 manufacturers to provide a product that can be easily 23 manufactured, packaged and shipped, or the needs of consumers 24 requiring economical and versatile do-it-yourself storage Atty: McHale & Slavic, P.A.
Atty. Docket No. L 251.320 4 1 kits. Moreover, because the prior art devices do not break 2 down they are difficult and expensive to ship from the 3 manufacturer to the consumer.
4 Paramount among such needs is an easy to assemble kit which can be easily assembled by an average homeowner.
6 Structure is a further consideration; a cabinet formed from 7 separate panels must create cabinet walls which resist panel 8 separation, buckling and racking in such a way as to unify 9 the entire enclosure.
I0 Also, from a versatility standpoint, a cocperating 11 drawer and guide should be present which can be easily 12 assembled oz modified after assembly of the side, top, base 13 and back panels, and which provides security and dependable I4 access to the contents of the drawers without the complex and IS difficult to assemble mechanisms associated with the prior I6 art .
17 There are also commercial considerations that must be I8 satisfied by any viable drawer cabinet system or kit;
19 considerations which are not entirely satisfied by state of 20 the art products. The drawer cabinet must be formed of 2I relatively few component parts that are inexpensive to 22 manufacture by conventional techniques. The drawer cabinet 23 must also be capable of being packaged and shipped in a 24 knocked-down state.
Atty: McHale & Slavin, P.A.
Atty. Docket No. 1251.320 5 i In addition, there are ergonomic needs that a drawer 2 cabinet system must satisfy in order to achieve acceptance by 3 the end user. The system must be easily and quv~ckly 4 assembled using minimal hardware and requiring a minimal number_ of tools. further, the system must not re~:~uire 6 excessive strength to assemble or include heavy component 7 parts. Moreover, the system must assemble together in such a $ way so as not to detract from the internal storage volume of 9 the resulting wall cabinet or otherwise negatively affect the utility of the drawer cabinet.

Atty. Docket No. 1251.320 I Brief Description of the Invention 2 The present invention provides an assembly, or kit, of 3 injection molded panels having integrated connectors which 4 combine to form a drawer cabinet with integrally formed guide rails and cooperating pull out drawers supported upon a 6 plurality of rollers. The cabinet panels are formed of 7 injection molded plastic and include integrally formed 8 connectors to interlock with one another without the need for 9 separate fasteners. The integrated connection of the side, IO back, top and base panels simplifies the drawer cabinet Il construction and minimizes the number of components required 12 to assemble'the drawer cabinet. Injection molding allows the 13 panels to be formed with integral cross-bracing, ribs and 14 gussets for increased rigidity. When supplied as a kit, IS assembly of the drawer cabinet requires minimal hardware and I6 a minimum number of hand tools.
I7 The drawer cabinet assembly includes a base panel, left I8 and right side panels and a top panel. The base panel is I9 constructed with integrally formed outwardly extending 20 contoured locking posts for interlocking cooperative 21 engagement with sockets formed into the bottom surfaces of 22 the left and right panels. The engagement between the 23 locking posts and the sockets serve to rigidly connect the 24 components together, preventing the panels from bowing Atty: McHale & Slavin, P.A.
Atty. Docket No. 1251.320 1 inwardly or outwardly under loads to provide a structurally 2 sound cabinet with a pleasing aesthetic appearance. The 3 construction of the panels minimize complexity of completing 4 the assembly while increasing versatility by allowing the consumer to customize the assembly for specific needs. For 6 example, the bottom surface of the base panel includes 7 sockets allowing the base panel to be used as a top panel.
8 This construction permits the multiple drawer cabinet units 9 to integrated into a multiple drawer cabinet. Alternatively, the drawer cabinets may be placed in a stacked arrangement 11 having the lower surface of one drawer cabinet removeably 12 engaged with the upper surface of another top panel of an 13 adjacently positioned drawer cabinet.
14 The interior portion of the cabinet includes integrally molded horizontal channels extending along each side. The 16 channels extend from the front portion of each side panel to 17 the rear portion of each side panel. Each channel is 18 constructed and arranged to accept an outwardly depending 19 drawer guide rail in a cooperating arrangement to prevent drawer tipping during extension and insertion ther_eof_ The 21 base panel includes a plurality of rollers secured within the 22 base panel in a manner to cooperate with the bottom surface 23 of the drawer member, allowing the drawer to be easily moved 24 when loaded. In a preferred embodiment, a first pair of Atty: McHale & Slavin, P..A.
Atty. Docket No. 1251.320 1 rollers are positioned to support the front portion of_ the 2 drawer member and a second pair of rollers are positioned to 3 support the rear portion of the drawer.
4 The snap together construction minimizes complexity of completing the assembly while increasing versatility by 6 allowing the consumer to customize the assembly for specific 7 needs. The built-in construction of the drawer guide 8 channels and rollers eliminates the need for skilled 9 tradesmen to line-up and mount complicated hardware within the cabinet. In this manner, the consumer can select one or 11 a plurality of drawer cabinets having various heights, snap 12 together the panels in the desired configuration, and 13 thereafter slide in the drawers to complete the assembly.
14 The drawers are pre-constructed of polymeric material and include a pair of integrally formed handles that allow a 16 removed drawer to be easily transported.' The bottom surface 17 of the drawer members are adapted to cooperate with the 18 rollers for easy movement in and out of the cabinet even when 19 heavily loaded. In addition, the bottom surface of the drawer member includes an alignment pocket adapted to 21 cooperate with the upper surface of the top panel of the 22 cabinet for removeably fixed placement outside of the 23 cabinet., Arty: McHale & Slavin, P.A.
Atty. Docket No. 1251.320 9 1 In operation, as a loaded drawer is pulled outward it 2 rolls freely on the rollers, utilizing the track and channel 3 combination prevent the drawer from tipping. This 4 construction allocns the drawers to be easily opened with heavy loads without requiring complex sliding track 6 mechanisms to prevent tipping of the drawer.
7 Accordingly, it is an objective of the present invention 8 to provide a polymeric drawer cabinet assembly having 9 integrally formed guide assemblies and at least one cooperating drawer.
I1 It is a further objective of the present invention to 12 provide a drawer cabinet assembly having an integrally formed 13 drawer guide, by which a cooperating drawer can be smoothly 14 guided inwardly and outwardly of a cabinet body without the need for complex metal guiding mechanisms.
16 Yet a further obj ective of the present invention is to 17 provide a drawer cabinet assembly having an integrally formed 18 drawer guide which allows the drawer to be guided a 19 sufficient distance out of the cabinet body to provide access to the interior of the drawer without tipping.
