6 Claims. (Cl. S12-330) This invention relates to improvements in desk top structures.

The customary office desks in general use include a desk top plate which, in a wooden desk, usually comprises a glued together assemblage of wooden boards or narrow planks. Below the top and supporting 1t are the usual pedestals and one or more desk slides are fre quently provided which are disposed at the top of the pedestals but below the desk top proper. A central drawer is likewise provided which is usually guided by the sides of the pedestals and supported wholly below the desk top.

With sheet metal desks the construction is substantially the same except that frequently the top plate of the desk is covered with a linoleum cover and, in addition, frequently the pedestal ends come up and flange over the top of the desk top.

According to the present invention a new relation of parts is provided for. In lieu of the slides and the central drawer being disposed below the desk top, these slides and the drawer are disposed within the desk top proper, particularly in a desk top designed to have e appearance of a unitary or distinctive top element as such. With such a construction it is of course necessary to provide space in the desk top to accommodate both the slides and the central drawer if such drawer is used. While the slides can be made relatively small in their vertical dimensions, slightly greater depth must be provided to accommodate the drawer in the top structure assemblage.

It is accordingly an object of the present invention to provide a set of sheet metal assemblages including metallic top plate, linoleum cover, reinforcing members, channels, and irons all disposed in a compact vertical relation so that the final desk top assemblage resembles a conventional desk provided with a relatively thick plank-like top. Such plank-like top has, of course, a thickness greater than that of the conventional wooden desk top, but its vertical dimension must be limited so as not to give a top heavy appearance to the desk. The desk slides and drawer have a configuration conforming with that of the desk top so that they are practically invisible when closed in the top of the desk.

Further and other objects of the present invention will be hereinafter set forth in the accompanying speciflcation and claims and shown in the drawings which, by way of illustration, show what We now consider to be one and a preferred embodiment of the invention.

Fig. 13 is another detailed view taken on line 13-13 of Fig. 5, looking in the direction of the arrows.

In more detail, the top writing surface of the desk preferably comprises a sheet of linoleum designated 20 (see Figs. l, 3 and 4). For supporting the linoleum a sheet metal base plate 21 is provided. This sheet metal base plate at the rear of the desk is curved arcuately downwardly, as shown at 22 in Fig. 3, and at the front of the desk such plate is curved arcuately downwardly, as shown at 23 in Fig. 4, and is provided with an inturned lip portion 24. The curved portions 22 and 23 substantially form circular arcs. Since the desk top is shown turned over in Figs. 3 and 4, the curves 22, 23 curve upward from the base plate 21.

For reinforcing the base plate and providing suitable rigidity a pair of trough-like flanged channels 25 are provided (see Fig. 2). The base portions of the troughs of these channels (see Fig. 7) are preferably secured by spot welding to the base plate 21. Flanges 26 of these trough-like channels are provided with a number of bolt Extending across the flanged trough-like channels are a pair of flanged U-channels generally designated 28 (see Figs. 6 and 2). The U-flanged channels 28 are preferably secured by bolts 29 (see Fig. 2) which pass through the holes 27 in the flanges 26. By selecting the holes which are to receive the bolts and shifting channels 28, such channels can be placed at desired distances apart depending on the size of the slide or drawer which is to be used.

The channels 28 just described (see Fig. 6) also have secured thereto, as by spot welding, guide channels 30. These guide channels 30 constitute the guide rails for receiving the guide rail slides on the desk slide or desk drawer (see Fig. l0). In this figure the cooperating guide rails on the drawers or slides are indicated at 31.

Limit stops 32 are preferably secured by spot welding to the flanges 33 of the U-shaped channels 28 (see Figs. 6, 3 and 2).

At the ends of the desk (see Figs. 5 and 8) there are U-channels 35. The flanges of these U-channels are secured by spot welding to the flanges 26 of the troughshaped channels 25. Fixed to the channels 35 (see Fig. 8) by spot welding are guide channels 36 which receive the guide rails on the cooperating desk slide or desk drawer. It will be understood that there is a cross channel member 35 at both ends of the desk (see Fig. 2). Disposed at intervals within the channel 35 there are nuts 37 (see Fig. 8) which are welded to the inside of the channel. These nuts receive the bolts which attach the pedestal to the desk.

Front reinforcing element Extending completely across the desk at the front are bent up sheet metal members 40 (see Fig. 4). These members 40 have flange portions 4l which extend over the flanges 33 of the trough-shaped channels 28. Such flanges 41 are also shown in Fig. 2 and the fastening bolts are indicated at 42.

As shown in Fig. 4, the member 4t) abuts against the base plate 21 and it is preferably secured thereto at intervals by spot welding. The member 40 extends within the curved flange 23 and near its end is provided with a bent back lip portion 44. The lip or flange portion 44 extends adjacent the` lip 24 and a linoleum fastening clip 45 is provided having a bead portion which extends over the surface of the linoleum. This linoleum clip member 45 is secured to the reinforcing member 40 by screws 46.

At the rear of the desk (see Figs. 3 and 11) there is a substantially similar construction, i. e., there is a member 40a provided with a flange 41a which is adapted to be bolted to flange 33. There is a flange 44a receiving the linoleum clip 45a and the bent end 22 of plate 21 also has an inturned flange 24a. Screws 46a secure these parts together.

To complete the semi-circular curvature at the rear edge of the desk there is a sheet metal member 47 which has an inturned flange 48 which abuts over the top of the linoleum clip strip 45a (see Figs. 3 and l1). Member 47 is provided at its ends with inturned flanges 52. To secure member 47 in place a number of Z bars 49 are provided (see also Fig. 2). These Z bars are fastened to member 47 by screws 50 which take into nuts 51 on the underside of the Z bars. The lower flanges of the Z bars 49 are welded to the flange 41a of member 40a.

End cap construction At each end of the desk top there is a sheet metal end cap stamping 54. This sheet metal cap has extended flanged portions 55 which are preferably spot welded to the sheet metal base plate 21. In order to provide room for the end flanged portions 55 member 40a is notched at the end as indicated at 56 in Fig. 13. Each end cap 54 is provided with a plurality of bolt receiving apertures such as 60 (see Fig. 2). These bolt receiving apertures are adapted to receive bolts which take into the weld nuts 60a in channels 35 (see Fig. 8). Bolt holes 61 are also provided in the U-flange of channel 28 (see Fig. 6). Suitable weld nuts are provided as indicated at 62 to receive the bolts which pass through the bolt aperture 61. The bolt apertures 60 and 61 are for the purpose of attaching the desk top assemblage to the pedestals. The end caps 54 are also preferably spot welded to channels 35 where the flange 54a of the end cap abuts the channel.

Referring now to Fig. 9, this figure illustrates the desk top structure and shows a left desk slide generally designated 63, a center drawer 64, and a right desk slide 63. These are shown in this figure partially drawn out. It will be understood that these desk slides and drawer are provided with channel rails which cooperate with the channels 36 and 30 (see Figs. 2 and 10). p

As shown in Fig. 3, the rear edge of the desk top has a substantially semi-circular curvature. This curvature is defined by the curvature of member 47 and by the curvatuer of the linoleum surface which overlies the arcuate curved edge 22 of the base plate.

The front of the desk with the drawer or desk slide slid fully in presents a similar semi-circular curvature. The bottom segment of this semi-circle is completed by the curvature of the front of the desk slide or front of the drawer which has a shape similar to element 47 (see Fig. 9A which shows a center drawer and Fig. 9B which shows a desk slide).

The space for concealing the desk slides or drawer is the space above the top of the linoleum clip (in Fig. 3) but below the clip when the top assemblage is turned over. Substantially the entire height of the . U-flanged channels 28 and 35, less the thickness of their flanges, is available to receive the drawers or slides.

Rigidity of the front edge of the desk is provided for by the reinforcing member 40 (Fig. 4) which extends completely across the front of the desk within the arcuate portion 23. Rigidity of the rear of the desk is provided for by member 40a which likewise extends completely across the desk, Further rigidity is provided for by the closing member 47.

Rigidity at the end of the desk is provided for by the cross U channels 35 which are finally housed in by the end cap stampings 54. As explained before, the end cap stampings are also fastened by spot welding to the base plate 21 and to the U channels 35.

The transverse flange members 28 can be bolted to the flanges 26 of the trough-shaped members and to the flanges 41 and 41a of the front and rear reinforcing members at various lateral positions, depending upon the width of the drawers which it is desired to accommodate, the width of the desk slides, and depending upon the type of pedestal arrangement with which the top is to be used. Pedestals are of different widths and, by placing these members in the proper position and then fastening them by the bolts, interchangeability and adjustability are secured. Where interchangeability or adjustability is not necessary spot welding may be used in lieu of the bolts and nuts.

As will be seen in Figs. 5 and 8, the linoleum strip 20 at its end abuts with and is flush with the marginal edge of the closure cap 54. The surface of the linoleum at the front and rear edge portions of the desk is kept in arcuate shape by the arcuate shapes 22, 23 of the underlying base plate. The edge of the linoleum at these points is retained in position by the linoleum clips 45 and 45a. It will be understood that the linoleum sheet 20 is preferably cemented to the base plate 21.

It is to be understood that the invention is not limited to the specific desk top herein shown or described but may be embodied in other forms without departure from its spirit.
