KNOCK DOWN DESK OR BENCH

Abstract

A light weight knock down desk or bench in which the various components of the desk or bench are assembled together without the use of tools or fasteners. The various components are flat panels or panel like members, some of which include integrally formed hooks or tabs extending from their edges and some include slots for receiving such hooks or tabs to interlock said components. Preferably the components include end panels, a vertical cross member having integral hook members extending from each end, a horizontal cross member having integral tabs extending from each end and a top work surface panel having tabs extending from each end. The integral extending hooks and tabs engage appropriately located slots in the end panels.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] In the preferred embodiments, the panels or panel like components of the desk or bench are made from sheets of a wood instead of a composite material. All of the components are thus flat panels or panel like members. Composites are heavier than wood. Preferably the wood used is Baltic Birch Plywood. The term “panel like” component or member refers to the fact that a component is made from flat sheet material, though it may have a configuration that would not normally be considered a “panel.”

[0021] Three, alternative embodiment desks 1-3 are disclosed, all having the same basic components, but with variations in some of the components. By “mixing and matching” the varying components, further variations in desks 1, 2 or 3 can be obtained. The various components and features are numbered in the drawings and description as indicated in the following parts list:

PARTS LIST

[0022] End panels 10, 10 and 10b [0023] Slots 11 or notches 11a for receiving top panel tabs 42 [0024] Slots 12 for receiving tabs 32 of horizontal cross supports 30 [0025] Vertical slots 13 for receiving projecting integral hooks 21 on vertical cross piece [0026] Vertical cross support and panel connector 20 [0027] Projecting hooks 21 [0028] Projecting tab 22 [0029] Horizontal cross support panel 30 for stability [0030] hand hold opening 31 [0031] end tabs 32 [0032] tab receiving slot 33 [0033] Top panel or work surface member 40, 40a, 40b, or 40c [0034] Accessory groove 41 for holding pencils, computer tablets or reference materials [0035] End tabs 42 [0036] Locking pegs 50

[0037] Desk 1 is made of two rectangular end panels 10, a vertical cross support 20, horizontal cross support panel 30 and top panel or “work surface member” 40 (FIGS. 1-5). Each end panel 10 includes two slots 11 near the top edge thereof for receiving the two top panel tabs 42 integral with and projecting from the end of and in the plane of top panel/work surface member 40 (FIG. 3). Two smaller slots 12 are located in end panel 10 somewhat below slots 11. These are for receiving integral tabs 32 of horizontal cross support panel 30. Finally, each panel 10 includes centrally located vertical slots 13, one located above the other, for receiving projecting integral hooks 21 on vertical cross piece member 20.

[0038] A flat panel like vertical cross connector 20 includes a pair of hooks 21 integral with and in the plane of said connector 20, at each end thereof (FIG. 1). Hooks 21 hook into slots 13 of each end panel and serve to lock the spaced end panels 10 together. Cross support/connector member also provides support for horizontal cross panel 30 and includes a top tab 22 which engages slot 33 in horizontal support panel 30.

[0039] Horizontal cross support panel 30 includes two tabs 32 projecting from each end thereof (FIG. 2). Tabs 32 are integral with and in the plane of horizontal support panel 30. These tabs fit into slots 12 on spaced end panels 10. Horizontal cross support panel also includes a centrally located slot 33 into which top tab 22 of vertical cross support is inserted when horizontal panel 30 is in place. Panel 30 also includes a hand hold opening 31, located between slot 33 and the front or back edge of panel 30.

[0040] Horizontal cross support panel 30 is multifunctional. It provides: (1) strength and stability to the unit, (2) it connects and locks the spaced end panels 10 together, it provides a storage shelf underneath the top work surface 40, and (4) a hand hold whereby the assembled desk or bench 1 can be lifted and moved.

[0041] Top panel 40 provides the work surface for desk or bench 1 (FIGS. 3, 4). It includes two tabs 42 projecting from each end, which are integral with and in the plane of top panel 40. In assembly, tabs 42 project into slots 11 near the top edge of each of the end panels 10. Preferably, top panel 40 is provided with a decorative upper work surface, or a chalk board surface, or a dry erase writing surface.

[0042] While a customer might find various ways to assemble the components of desk or bench 1, FIGS. 1-4 provide a convenient order as numbered. Cross support 20 is hooked into vertical slots 13 of a first end panel 10 (FIG. 1). Horizontal cross support panel 30 is assembled next by having its projecting end tabs 32 slid into slots 12 in end panel 10, and then its slot 33 lowered down over tab 22 of vertical support 20 (FIG. 2). The projecting end tabs 42 of top panel 40 are slid into slots 11 of an end panel 10 (FIG. 3). Finally, the various hooks and tabs at the other end of the assembly are inserted into a second panel 10 (FIG. 4), resulting in the assembled desk 1 (FIG. 5). Locking peg 50 is shown in FIG. 5 inserted into slot 13 from the outside of panel 10, after book 21 is in position in slot 13. This locks vertical cross support member in place.

[0043] FIG. 6-h 8 discloses an alternative desk 2 and alternative desk 3 having “I” shaped end panels 10a. Since end panels 10a are narrower front to back than end panels 10, the tabs 42 on top panel 40a are spaced closer together. As a result, top panel 40a projects outwardly a bit from between end panels 10a. Desk 2 also differs from desk 1 in that an accessory groove 41 is provided in the work surface of top panel 40a. Preferably, groove 41 is sufficiently deep that it can accommodate pencils and the like, but also such that it can receive a computer tablet and hold it upright in groove 41.

[0044] FIGS. 7 and 8 disclose a desk 3 variation from either desk 1 or 2, which accommodates the use of a reversable top panel 40b. Specifically, end panels 10b include upwardly opening notches 11a at the top edge of the panel, in place of slots 11. This facilitates the use of a top panel 40b having two different work surfaces located on the opposite surfaces of panel 40a. The open notches 11a allow tabs 42 on top panel 40b to be simply lowered into or lifted out of notches 11a when the user wants to use either of the alternative work surfaces. (As shown, the end panels 10b are of the “I” shaped type but could also be either the rectangular type panel 10 or the “X” shaped type panel 10c shown in FIG. 1.)

[0045] Preferably top 40b is optionally provided with a chalk board surface on one side and a dry erase writing surface on the other. Both sides include the accessory groove 41, but, they are offset from one another in order to accommodate the required depth for the grooves 41 to support a tablet computer in an upright position (FIG. 10).

[0046] Alternative desk 4 is like desks 1 and 2, except that it includes “X” shaped end panels 10c, and its top panel 40c is provided with a hand hold opening 42 adjacent one of the lateral edges of top panel 40c. The variations in component features can be varied in other ways to create other variations in the overall design of the knock-down desk or work bench.
