No. 554,483 6 (llaims. (Cl. 312-263) ABSTRACT @F THE DESGLGSURE Knockdown cabinet construction which can be as-- sembled without the use of tools and in which the various parts interlock with each other to eliminate the need for fasteners such as nails.

This invention relates to cabinet assemblies and drawers therefor, and more particularly to cabinet asemblies of the wall and base type suitable for use in home construction and remodeling.

Generally, cabinets have been manufactured and assembled in a cabinet shop or factory and transported to the site for installation. The cabinets in their assembled form occupy a large cubage and are, therefore, expensive to transport and store.

More recently, there has become available pre-cut, unassembled cabinets which can be assembled by the home owner. However, such cabinets are generaly nailed and glued together presenting a considerable problem to the average home owner. There is, therefore, a need for an easy to assemble cabinet and drawer assembly to satisfy the demands of the do-it-yourself home owner.

It is a general object of the invention to provide a cabinet assembly and drawer which will overcome the above named disadvantages.

Another object of the invention is to provide a cabinet assembly and drawer which is pre-fabricated for easy assembly at the destination.

Another object of the invention is to provide a cabinet assembly and drawer of the above character which can be assembled very rapidly and which does not require tools, nails, screws or glue to form its joints.

Another object of the invention is to provide a cabinet assembly and drawer of the above character which, when assembled, is locked together so that it cannot be disassembled in normal use.

Another object of the invention is to provide a cabinet assembly and drawer which can be easily disassembled for storage in a small package.

Further objects and features of the invention will appear from the following description in which the preferred embodiment of the invention has been set forth in detail, in conjunction with the accompanying drawings.

BASE CABINET Referring now to FIGURES 1 and 2, there is shown a base cabinet assembly incorporating the invention.

States Patent 0 In general, the cabinet includes a face frame or front panel 11,

side panels

12 and 13, top and bottom panels 1d and 17, a back panel 13, shelf panels 1%, b, and a drawer 20.

Face frame or front panel 11 includes an opening 21 to one side of which is mounted a door 22. Door 22 is pre-hung in a conventional manner and is not required to be installed by the user. A second opening 23 is provided for permitting the drawer to pass through front panel 11.

Vertical dovetail slots

25 and 25 are formed along each side margin on the rear of front panel 11 and extend its full height.

Horizontal slots

27 and 28 are formed along the upper and lower margins of the rear side of panel 11 and cross each of the

slots

25 and 26 near the corners.

Slots

27 and 28 are formed with a square cross-section for receiving the front edges of top and bottom panels l d and 17.

Side panels

12 and 13 are mirror images of each other and, therefore, will be jointly described. The front edge of each of the panels 12 and i3 is formed with a vertical tongue 29 having a dovetail shape in cross-section. Tongue 29 faces forwardly and is adapted to slidably fit into and engage one of the

slots

25 or 26 in the front panel.

Side panels

12 and 13 are further provided with

horizontal dovetail slots

31 and 32 extending along the upper and lower inner margins. Additional horizontal slots or

grooves

33, 34 are formed in the

side panels

12 and 13 are parallel to the top and bottom. Slot 33- is dovetailed in cross-section and is spaced from slot 31 a distance somewhat greater than the depth of drawer 20 so that it can support the same.

Rear edges of

side panels

12 and 13 are formed with vertically extending grooves 35, 36 along their rear inner margins to receive back panel 18, the side edges 5d of which are received in grooves 36.

Top and bottom panels 1-5 and i7 and shelf panel 19 are provided with outwardly facing tongues 41a, b, c, :1, 42a, b, c, d, along their side margins which are adapted to fit into and engage

slots

31, 32, 33 and 34, respectively, in

side panels

12 and 13. Shelf panel 19a has a dovetail slot 43 extending from front to rear along the upper middle surface thereof for receiving a runner guide 44.

Guide 4% comprises a fiange 43 for abutting the top surface of the shelf for support, and a downwardly extending tongue 46 having a dovetail shape in cross-section and adapted to engage slot 4 3 in shelf 19a. Runner guide further includes transversely projecting

elongate ribs

47 and 48 on each side of the guide, the ribs being spaced from the flange and adapted to be engaged by a drawer runner 49 as hereinafter described in connection with the drawer 2t).

DRAWER Referring now to FIGURES 3 and 4, there is shown a drawer comprising a front panel 51,

side panels

52 and 53, a bottom panel 54 and a back panel 55. Front panel includes vertical dovetail slots 5'7 and 58 spaced slightly from the sides and along the rear surface thereof and extending from the bottom to a point spaced from the top. The front panel further includes a horizontal slot 59 having a square cross-section and extending along the lower margin, spaced from the lower edge and running from side to side. The front edge of the bottom panel 54 is adapted to fit into slot 59.

The front edges of

side panels

52 and 53 are formed with tongues 61 and 62;, each having a dovetail shape in cross-section.

Side panels

52 and 53 have grooves es and 64 along their inside lower margins extending from front to rear, for receiving the side edges 65 of bottom panel 54.

Sid panels

52 and 53 further have vertical dovetail slots 66 and d7 spaced slightly from their rear margins.

The side edges of the back panel 55 are formed as outwardly facing

dovetail tongues

68 and 69 adapted to engage

slots

55 and 67 of the side panel. The bottom edge of back panel 56 is relieved along its inner corner to form a rabbet 71 for overlap ing bottom panel after drawer is assembled.

The assembly of the base cabinet and drawer will now be described.

DRAWER ASSEMBLY The drawer is assembled by sliding side panels 52 and '3 upwardly so that tongues 62 of the panels 52 and 53 g and slide along

slots

57 and 58 in the front panel 1 until the upper ends of the tongues abut at the upper ends of the slots. Bottom panel 54 is then slid through grooves 63 and 64 of side panels 61 and 62 until its front edge projects into slot 59 in the front panel 51 to thereby lock

side panels

57,, 53 and bottom panel 54 vertically with respect to front panel 51. Back panel 56 is then slid downwardly so that

tongues

68 and 69 engage

slots

66 and 67 in the side panels 61 and 62. The length of bottom panel 54- is such that when the same is fully home in slot 59, the rearmost edge extends partially through

slots

66 and 67. Rabbet 71 is adapted to overlap the rear edge of the bottom panel that the bottom panel cannot be removed when the back panel is in place.

The drawer assembly just described is effectively retained together in a sturdy solid unit by the action of the dovetail joints formed between the tongue and

groove members

61, 62, 57, 58 between the side panels and front panel, and the tongue and groove dovetail joint formed between

slots

65, 67, and

tongues

68 and 69. The slots 63, 6d and side edges of the bottom need not be constructed in an interlocking fashion since the drawer is held together by the remaining joints.

CABINET ASSEMBLY Cabinet 10 is assembled as follows: It is convenient to lay front panel 11 face down on a suitable supporting surface. Side pane.s 12 and 13 are then slid so that tongues 29 engage

grooves

25 and 26.

Side panels

12 and 13 are then adjusted so that the

slots

31 and 32 are generally aligned with

slots

27 and 28 so that top and

bottom panels

16 and 17 can be slid through the latter slots and forwardly into

slots

27 and 28 to thereby lock the side panels vertically with respect to front panel 11. Back panel 18 is then slid onto the rear of the

side panels

12 and 13 so that the slots 3-% and 36 engage edges 50. Kick panels 72 and '73 are provided in the side panels and below the bottom panel.

It will be seen that the tongue and groove interlocking joint formed between the side panels and the front panel is locked in place by the front edges of top and

bottom panels

16, 17 which engage

slots

27 and 28. Top and

bottom panels

16, 17 are in turn locked together with the other members by back panel 18 to thereby form a solid sturdy cabinet structure. Back panel 18 need not be further secured because it will be supported by being nailed to the wall or by being rested on the floor. Back panel 18 is provided with a cleat 75 to take up the space between the wall and the panel 18 and support the same when it is nailed to the wall in installation.

Drawer 20 is inserted in the cabinet so that runner 4-9 on the back panel 5-3 engages ribs 47, d8 of guide 44. Guide 44 also prevents back panel 56 from being raised. since runner 4-9 is retained by ribs 47, 4S and can only slide horizontally with respect thereto. Thus, the drawer cannot be disassembled inadvertently since it must be completely removed from the cabinet in order to lift the back panel. The drawer is supported at the front of the drawer shelf by suitable means, such as plastic drawer guides 78 and 79 which are fastened to shelf 19a.

d WALL CABINET FIGURE 5 illustrates a cabinet assembly of the wall cabinet type incorporating my invention. In general, my wall cabinet includes a face frame or front panel 81,

side panels

82, 83, top and

bottom panels

84, 85, and back panel 87.

Front panel 81 includes an opening 91 to one side of which is mounted a door 92 which is pre-hung to the frame in a conventional manner.

Vertical dovetail solts

93, 94 are formed along each side margin on the rear of front panel 81 and extend its full height.

Horizontal slots

96, 97 are formed along the upper and lower margins of the rear side of front panel 81 and cross the slots 93, 9 1. Slots 9-5, 97 have a square cross-section.

The front edges of

side panels

82 and 83 are formed in a forwardly elongate facing dovetail tongue 98. The rear inner margins of said

panels

82, 83 are provided with vertically extending slots 99 having a square cross-section.

Side panels

82, 83 are further provided with

horizontal slots

101, 102, 103, 104 along the upper and lower inner margins and extending from front to back.

Slots

101, 102 ar dovetail in cross-section. Top and bottom panels 84, 86 are provided with dovetail shaped

tongue

105, 106, 107, and 108 on their side edges which are adapted to engage

slots

101, 102, 103 and 104.

The side edges of back panel 87 are adapted to engage the slots 99 of the side panels. A narrow strip 110 of wood is fastened to the inside of back panel on the inside thereof, and extends perpendicularly between the side edges of back panel 87. Strip 110 is adjusted so that its upper edge abuts the underside of top panel 84. When assembled, additional strips 111, 112 are fastened to the top and bottom outer side of back panel 87 and serve to give it additional support when it is nailed to a wall.

WALL CABINET ASSEMBLY The wall cabinet is assembled by sliding

side panels

82, 83 onto front panel 81 so that the tongues 98 engage the slots 93, 94-.

Side panels

82, 83 are adjusted so that

slots

101, 102, 103 and 10 1 are in registry with

slots

96, 97. Then bottom panel 86 is slid forwardly through slots 103, 104 until its front edge lies within slot 97 to thereby lock

side panels

82, 83 vertically with respect to front panel 81. Back panel is then slid onto the rear of

side panels

82, 83, slots E9 engaging th sides of back panel 37. Back panel 87 is lowered to a position such that its upper edge lies below

slots

101, 102. The top panel 84 is then slid through

slots

101, 102 until its front edge projects into slot 96. Then back panel 87 is lifted upwardly until it overlaps the top panel 84-. The spacing of the strip 112 from the top edge of the back panel is adjusted so that when back panel 87 is lifted upwardly until the top edge of strip 110 contacts top panel 84, and back panel 87 is correctly positioned vertically with respect to the remainder of the cabinet. Reversing the assembly, procedure of the top, bottom and back panels will reverse the direction of door opening of the wall cabinet.

Adjustable shelves

116, 117 are then placed on metal shelf pins 110 provided in pre-drilled holes to receive same in the

side panels

82, 83.

It will be seen that the tongue and groove interlocking joints formed between

side panels

82, 83 and front panel 81 and the projection of the front edges of top and bottom panels 84, 86 into

slots

96, 97 locks the side panels and front panels together as a rigid unit. The back panel 37 is not free to be moved upwardly (nor the cabinet downwardly) since the upper edge of strip 110 :is in contact with top panel 34 to support the entire cabinet. Thus, when back panel 87 is nailed to a wall as in a common kitchen installation, the wall cabinet cannot be removed or dissembled without unnailing it from the wall.

While I have showed the invention as incorporated in a base cabinet, drawer and wall cabinet, it will be understood that the invention is not limited to the details of construction shown and that other forms or combinations can be used without departing from the spirit and scope of the invention. For example, while there are shown certain joints as having been formed in dovetail configuration, it will be understood that other interlocking configurations may be used provided they are capable of locking engagement with each other. The dovetail joint shown is preferred, however, since it is reasonably easy to make with commonly available power tools.

Further, it is obvious to those skilled in the art that many of the tongue and groove joints employed in my cabinet assemblies can be reversed in structure; that is to say, by overlapping the parts in opposite order and then exchanging the positions of the tongues and slots.

I claim:

1. In a knock-down cabinet construction, a front panel having a pair of spaced parallel dove-tailed grooves formed therein on its inner side and spaced parallel upper and lower grooves also formed on its inner side, a pair of spaced side panels having dove-tailed front edges seated in the dove-tailed grooves in said front panel, said side panels each having spaced upper and lower dove-tailed grooves formed therein on their inner sides, top and bottom panels having dove-tailed side edges seated in the upper and lower dove-tailed grooves in said side panels and having their front edges seated in said upper and lower grooves in said front panel to prevent sliding movement of the front panel relative to the side panels, the seating of said front edges in the upper and lower grooves of said front panel preventing movement of the front edges of the side panels in the dove-tailed grooves of the front panel, said side panels each having grooves therein adjacent the rear edge on the underside thereof and a rear panel having its side edges seated in the grooves of the side panels adjacent their rear edges, said rear panel overlapping the rear edges of the top and bottom panels and preventing the top and bottom panels from being shifted in the grooves in said side panels.
