10 Claims. (Cl. 311-497) The present invention relates to desks or the like, and more particularly to an improved top for desks and tables of the type used in classrooms. This application is a continuation in part of my co-pending application Serial No. 339,353, filed February 27, 1953, now abandoned.

The primary objects of the invention are to provide a top for a desk or the like which is especially durable and resistant to disfigurement by accidents and vandalism which often occur in schools; to provide such a top which is exceptionally sturdy in construction; to provide such a top which lends itself well to production methods; and to provide such a top which is attractive in appearance.

Illustrative embodiments of the invention are shown in the accompanying drawings, wherein:

Figure 9 is a perspective View of a further modified form of top;

Figure 10 is a fragmentary vertical sectional view of the same taken on line 1o1l) of Figure 9; and

Figure 11 is a perspective view of the modified form of top shown in Figures 9 and 10, the several parts of the top being here shown in disassembled relation.

Referring now in detail to these drawings wherein like parts are designated by the same numerals in the several views, and referring first particularly to Figures 17, the desk there illustrated has a vertical supporting column 10, here shown fragmentarily, which may be of any suitable height and which may have its lower end connected to any conventional type of supporting base (not shown). Mounted on the upper end of the support column 10 by suitable means is a desk box 11 of the type used in classrooms and adapted to contain books, supplies, etc.

The desk top is generally designated 12 and is hingedly connected at 13 to the upper front edge of the desk box (see Figure 2) so that the top may be lifted in the rear to give access to the desk box or lowered so that it closes the open top of the box and serves as a cover therefor. Other connections between the top 12 and the desk box 11 may be provided for cushioning the lowering move- 2,733,111 Patented Jan. 31, 1956 ice meat of the top, such connections being generally designated 14 and not being described here in detail since they do not form a part of the present invention.

As here shown the desk top 12 comprises a flat panel 15 of generally rectangular shape and which is composed of three plied up sheets of material, the upper sheet 16 (see Figures 6 and 7) being of a plastic material and having its upper surface in simulation of natural wood, the middle sheet or core 17 being of a suitable composition such as resin-impregnated wood fibre, and the lower sheet 18 being also of a plastic material. The three sheets are bonded together by a suitable adhesive.

Extending around the peripheral edge of the panel 15 is a molding generally designated 19. This molding is formed of strip sheet metal stock which is bent longitudinally to form an inwardly extending upper flange 20 (see Figures 6 and 7) which engages the upper surface of the panel 15 along its marginal peripheral edge. The strip stock depends from the upper flange 20 to form an outer rim 21 extending well below the panel 15, is then bent upwardly to form an inner rim 22 flush against the outer rim 21 and secured thereto as by means of spot welding, and is finally bent inwardly from the upper edge of the inner rim 22 to form an inwardly extending lower flange 23 which engages the under surface of the panel 15 along its marginal peripheral edge.

The molding 19 extends across the front edge of the panel 15, rearwardly along the side edges of the panel, and the opposite end portions of the molding are then turned inwardly toward each other along the rearward edge of said panel A connecting strip 24 has its opposite ends secured to said opposite end portions as by means of rivets 25 which extend through the strip 24 and through the inner rim 22 and outer rim 21 of the molding 19. The molding 19 is thus tightly secured in position on the panel 15. The connecting strip 24 extends above the upper rearward edge of the panel 15 and thus serves as a support for books or other articles as seen in Figure 1. This feature is particularly important in connection with desks having rearwardly-downwardly sloping tops.

Added rigidity is imparted to the desk top by means of a pair of parallel struts 26 of channel bar form, which have their opposite ends flanged outwardly to form tabs 27 which are secured as by means of spot welding to the opposite front and rear portions of the inner rim 22 of the molding 19. Brackets 28, likewise of channel bar form, each has its inner end secured to an intermediate portion of one of the struts 26 as by means of spot welding indicated at 29 in Figures 4 and 7. These brackets 23 extend lateraly outwardly from the struts 26 and have their outer ends flanged to form tabs 3% which are secured as by means of spot welding to the opposite side portions of the inner rim 22 of the molding 3.9. The upper surfaces of the struts 26 and brackets 2% lie adiacent the underside of the panel 15 and thus these struts and brackets form a sturdy support for the panel. Lugs 31 are struck downwardly from the brackets 23 and are adapted for attachment to the connections 14 between the desk box and desk top.

Rubber bumpers are inserted in openings through the struts 26 near the struts rearward ends, and these bumpers contact the upper rearward edge of the desk box when the top is closed so as to deadcn any noise which might occur when the top contacts the box at this point.

The desk top is assembled as illustrated in Figure 5. The frame comprising the molding 1?, struts 26 and brackets 23 is prefabricated by spot welding, and is sulfiiently sprlngable to permit the rearward ends of the molding to be separated as shown. The panel 15 is then inserted into the moldings groove between the flanges 2t) and 23, after which the connecting strip 24 is placed in position and the rivets are set to complete the desk top.

As seen in Figures 1 through 7, the upper plastic sheet 16 of the panel 17 .is of .slightly smaller dimensions than the other sheets of the panel, .so that the peripheral edge of the upper sheet 16 abuts the inner edge of the moldings upper flanage 2i) and the upper surfaces of said sheet 16 and flange 2% are thus in flush relation. In the slightly modified construction shown in Figure 8, the sheets 16 17 and 18 are flush at the edges and the flange 29 overlaps the marginal edge of the upper sheet lo). Either construction presents a neat and at tractive appearance.

In the modified form of the invention shown in Figures 9-11, the outer rim' 21 and inner rim 22 are separate elements. The outer rim 2.1 has an inwardly extending peripheral flange 2% at its upper edge, while the inner rim 22 has a peripheral flange 23 at its upper edge which extends inwardly below the flange M The inner rim is preassembled to the parallel channel struts 26 and to the channel brackets 2% as by welding to form a steel supporting frame as best seenin Figure 11, with the struts 26 spanning the frame. In assembling the composite top, the laminated top panel 16 is placed over this steel frame after which the outer rim 21 which is desirably of decorative metal such as aluminum or stainless steel, is wrapped around the inner rim 22 and the marginal edge of the top panel 16 thus clamping the top panel between the

spaced flanges

26 and 23 of the outer rim 21 and the inner rim 22 espectively. The lower edge 201 of the outer rim is then crimped around the lower edge of the inner rim as seen in Figure 10, and the outer rim and inner rim are then secured together as by means of rivets 2'92. The connecting strip 24 which forms a book support is finally secured in position overlying the juxtaposed ends of the outer rim, as by means of rivets 2%.

It will thus be seen that the invention provides a sturdy, durable and handsome top for a desk or the like, and while but several specific embodiments of the invention have been herein shown and described, it Will be understood that details of construction thereof may be altered or omitted without departing from the spirit of the invention as the same is defined by the following claims.
