Application March 4, 1950, Serial N 0. 147,635

This invention relates generally to" improved tables or desks characterized by various features of ruggedness, simplicity and adjustability rendering them particularly adapted for schoolroom use. In certain respects, the tables of the present invention represent improvements on the table shown in my copending application for patent, Serial No. 27,391, filed May 17, 1948, now Patent ,547,269, issued April 3, 1951.

The table structure of my above mentioned application comprises essentially a top,a pair of vertically adjustable end leg assemblies, and a rigid brace member or beam extending along the underside of the top between the legs. The general object of the present invention is'to provide improved tables of this general type incorporating particularly improved means for interconnecting the top, legs, and brace member in a manner maximizing the strength and rigidity of the assembled structure while at the same time facilitating erection of the table from a partially disassembled shipping condition- Preferably, I employ a rigidly constructed book compartment structure underlying the table top as the brace member to serve the dual purpose of strengthening the table structure and receiving books or other students supplies.

I attain the above structural rigidity combined with facility of erection by the employment of a pair of novel bracket plates specially formed and- Each of the leg assemblies of the present in-' vention' preferably includes a vertically extending sheet metal panel section turned inwardly at' its lateral edges to form a channel-like leg member open at its inner side. A further object of the invention is to so mount the previously mentioned brackets to the upper ends of these sheet metal panels as to. extend across their open inner sides and thus greatly strengthen the panels against deformation from their channel shaped form.

structurally, each of the brackets may'include' a first portion overlying the upper .end of the leg assembly and. a second portion extending downwardly between the leg assembly and the book compartment or other brace member. Upon erection, the upper horizontal portion of the bracket may be connected to the underside of the table top, and the depending portion connected to the 6 Claims. (01. 312255) adjacent endof the book compartment to rigidly interconnect the various parts in a mutually bracing relationship. Further strength and rigidity may be attained by forming the bracket plate to have a second horizontal portion extending beneath the book compartment and attached to its underside. The provision of this lower portion of the bracket is especially desirable where the table top is to be movably hinged to the book compartment and cannot itself be attached directly to the bracket or leg structure.

The above and further features and objects of the present invention will be better understood from the following detailed description of the typical embodiments illustrated in the accompanying drawing, in which:

' Fig. 1 is a perspective view of a preferred form of adjustable school desk embodying the invention, with the desk top partially broken away to show the construction of one of the bracket plates for interconnecting the top, book compartment and an end legassembly; t

The table or desk of Figs. 1 through 5, typically illustrated in a two-student size, comprises essentially an upper horizontal top It, a pair of end leg assemblies I I, a book compartment structure I2 extending along the underside of the desk top between the two leg assemblies, and a pair of.

angular bracket plates I3 acting to rigidly inter connect the table top, book compartment and leg I h I. 2,671,002

horizontal separation. Intermediate their curved side edges, these panels have a pair of vertically extending ribs 21 slidably interfitting to strengthen and guide the two panels in their telescopic relation. The two curved outer edges of inner panel l8 extend about and are welded to a pair of tubular legs 22 which project downwardly and outwardly for engagement with a supporting floor surface. A channel shaped member 23 extends between these two legs at a location near the bottom of the inner panel, and is welded at 24 to both the legs and panel to strengthen the lower leg section. As will appear later, the outer sheet metal section l9 of each leg assembly is connected through the corresponding bracket [3 to the table top, so that relative vertical movement between the two Sheet metal panels effects a vertical adjustment of the table. To retain the two panels any desired adjusted condition, the outer panel has two pairs of openings 25 selectively rcg-istrable with a series of vertically spaced pairs of 011ml.- ings 26 in .the inner section. Screw bolts :2] are inserted through any selected pairs of openings in the inner and outer sections to retain those sections in any adjusted condition.

As seen best in Figs. 1, 2 and 5, bracket plate l3 includes .an upper horizontal portion 21! .di.-.- rectly overlying the upper end of the outer leg panel 19 and welded to the upper edge of the panel at I91, preferably along substantially the entire extent .of that edge. This upper portion of the bracket extends horizontally beyond the panel for attachment to the underside of top 1.0 byscrews 28. From the inner edge of its upper portion 21!, the bracket plate extends downwardly at 3| between upper leg panel 9 and end wall It of the book compartment. This depending portion of the bracket plate is rigidly welded at 29 to the opposite lateral edges of the upper leg panel, and is attachable directly to the end wall of the book compartment by screws 30. At the lower end of its depending portion 3|, bracket plate l3 extends horizontally inwardly at 32 beneath the book compartment to further support that compartment and strengthen the table structure. This lower hori zontal portion of the bracket plate may be ,connected to the underside of the book compartment by screws 33.

The table is normally shipped in partially dis. assembled condition, with the top and book compartment disconnected at each end from theleg assemblies carrying the two brackets I3. In order to erect the desk, it is nefi cssary merely to attach the bracket plates to the opposite ends of the book compartment by

screws

30 and 33,, and then mount the top .10 to the bracket plate by screws 28. The leg assemblies may be easily and quickly adjusted to any desired height either before or after erection of the table.

Figs. 6 and '7 show a variational form of the invention corresponding in many respects to the Fig. 1 form, but having a movable top hinged to the rear of the book compartment at 31 for upward swinging movement to permit access to the book compartment from its upper side. In this form, bracket plate 38 is welded to the upper end of the upper sheet metal leg section 39 in the same manner as in Fig. 1, .but is in certain respects formed differently than the bracket I3 of the previous form. Specifically, the upper horizontal portion 40 of bracket 38 has no screw receiving openings for attachment tothe movable top, and is curved rather than rec- .4 tangular to present a smooth and regular appearance upon opening of the top. As in the previous form, the bracket plate has a vertical portion 4| extending downwardly between the leg assembly and the book compartment and attached to the book compartment by screws 42. Lower horizontal portion 43 of the bracket plate extends inwardly beneath the book compartmerit fur a greater distance than in Fig. 1 in order to compensate for the fact that in this form the bracket cannot be attached directly to the desk top. The erection of the Figs. 6 and 7 form of table is similar to the first form and produces a correspondingly rigid and strong structure.
