4 CIaiinsL This invention'relates to a desk? or table; top havingrounded corners and a molding, and the principal objects of the. invention areqto provide an improved form and construction. for such tops; to facilitate. the construction and assembly of the top; and to provide. improved means for securing a finish molding to the perimeter of the top.

More specifically, the invention relates to a desk or table top comprising asub-top and a filler top, both being pan shaped and; provided with side flanges that overlap when the pans are fitted together. The corners of. the pans are formed by a drawing operationafter an arcuate portion of each corner has been removed. A molding retainer not. only secures. the. pans; together, but also receives a strip or pliantmolding material that obscures the joined pans. and

' presents a finished appearance to the desk. or

Fig. l is a fragmentary, perspective view of.

one corner of a desk top constructedin accord.- .ance with this invention,v the. corner portion. being broken away to more clearly illustrate the form of the several parts which. are assembled to make the desk top with its ornamental edging;

Fig. 2 is an enlarged exploded view of the corner portions of the several parts which are assembled to form'the desk top;

Figs. 3 and 4 are fragmentary portions of the sheet metal stampings from which the sub-top and filler-top parts, respectively; are formed; and t 9 Fig; 5 is an enlarged, fragmentary,'sectional detail of the improved desk top, the section. being taken on the line 5-5' of Fig; 1.

A desk top constructedin accordance with this invention comprises a sub-top 6 and a filler-top 1' respectively formed from. sheet; metal stampings 6a and la and secured together in. opposed nested relationship and around. the perimeter of which is secured an ornamental edging or molding, generally designated 8.

The sheet metal stampings. 6a and la, .f-rom which the sub-top 6 and filler-top 1 are respectively formed, havethe four corners cutaway along inwardly extending,- angularly' disposed lines 9 and Ill, and an intermediate arcuate line H. The cuts 9 and I 0 are disposed at. right angles to each other and extend transverse to the: edges l2 and I3 of the corners of therespective stampings. The arcuatecut I l, between. the cuts 9. and I0, is formed onan axis substantially coincident with the intersection of'the planes of the cuts Band [0. For the stamping 1a,, the juncture of the cuts9 and lll andzthe edges mam I3 of that stamping are rounded, as indicated at M in Fig. 4.

(Cl. 311-107 )I Inwardly of and, parallel to the respective stamping edges 12. and B are rows of spaced apertures. l5. which, in the. subsequently assembled subandfiller-topssG and. 1, come into'registration to receive screws l6. by which the. two

tops are secured together and the. ornamental edging or molding 8 is ecured. in place. around the perimeter of thedesk top.

'I'heperimetrical'portions of eachof thestampings Ba and 1a between the arcuatecorner cuts II. are bent over to. form transverse flanges. l1 and i8 for. thesub-top B, and I9- and. 20. for the filler-top 1.. The. bend of these flanges is along lines 2|, as shown in Fig. 3, slightly inwardfrom thebase of. the cuts-.9. and I0; Thuainthe forming' of the flanges t1. and: 1.8,, and I9 and 211, the portion: of the stamping. intermediate. the. cuts 9 and I0; concentric with the. arcuate cut. H; is likewise folded over to form an arcuatefiange 2 3 onthe sub-topa-nd. an arcuateflangeidon the filler-top,v which. flanges connect. and. are continuous with. the. respective. flanges I]. and I81 and l9 and 20.

The flanges I1 and is for the. siih-top GI are again. bent along lines. 22. so that their perife metrical portions form. inwardly extending flanges 2.5. and 26; respectively, disposed parallel to the body of. the sub-top 6. Also, the flanges H and I8 aresofiset slightly inward'fromthe lines 21 so as toform a. ridge. or: bead. 21. coextensive with the respectivefianges I! and |.8.'

In forming the: rounded corners. for thesuband filler-tops, the-flanges H; l8, l9 and. 20 are first bent .down, and then suitable drawingfdies form. the. arcuate. flanges 23 and. 24. This provides. a nicely rounded, bent-over corner, of simple, yet sturdy,. construction.v

order. to. appropriately reinforce, the perimetrical-portions of theassembled'suband fillertops. 6 and. 1, Z-shapedl bars. 2 8. and 29 are insertecl. betweenandbond'ed to the flanges 2'5 and 26 and the. body of. the. sub-top 6, substantially co-extensivewith the. respective flanges, I1 and [8, as most clearly shown in Fig.. 5. In addition to thereinforcing. Zl-bars. 28 and 29, other suitable reinforcing bars are arranged. between the subtop. 6. andfiller-top I, as is shown and explained in. co-pending application, Serial. No. 697,760, filed September. 18;, 1946; now U; S. Patent No. 2,560,4HOI. v

The suband filler-tops 6' and 1. are assembled, as. most clearly shown in Figs. 1 and 5, with the flanges.- I! and 18' of. thesub-top 6'. nesting, within theflianges. l9 and. 20 of. the filler-top 1 andwith the upper edges of the flanges l9- and. 20 closely adjacent to the-riber bead 21- on the sup-top 6, it not in actual; contact therewith.

. Azfter'these: top: sections. are: assembled, a: sheet of linoleum 3|], or other suitable material, islaid on the body of the sub-top 6, and glued thereto,

with its perimeter coextensive with the ridge 21 and beveled, as shown in Fig. 5. The molding 8 is then applied. It comprises a retaining member 3| and an ornamental member 32, the former comprising a flexible strip of extruded metal, preferably aluminum. It is made channelshape, with the transverse parts or

flanges

33 and 34 of arcuate form. The upper longitudinaledge is enlarged and formed with an inwardly disposed inclined shoulder 35 which mates with the beveled edge of the linoleum or composition top and is flush therewith.

The arcuate form of the

transverse parts

33 and 34, of the channel strip 3!, provide pockets 36 and shoulders 3! which serve to hold the ornamental strip 32 on the strip 3| with the outer face of the ornamental strip 32 flush with and forming a continuation of the outer facesof the arcuate-shaped

transverse parts

33 and 34.

The ornamental strip 32 is made of extruded or molded pliant material, preferably in the nature of a synthetic material. As herein shown, it is of arcuate form with the exterior face grooved or otherwise rendered ornamental. The opposite longitudinal edges are recessed so as to provide tongues 38 which are adapted to extend into the pockets and abut the shoulders 31 so as to secure the ornamental strip 32 to the retaining strip 3 I. The retaining strip 35 is secured around the perimeter of the desk top by screws 16 entering the registering apertures 15 in the assembled suband filler-tops 8 and l. The strip, being formed of flexible material, may be bent to closely fit the rounded corners of the desk top so-that, if desired, a single strip of material may extend entirely around the desk or table top.

The ornamental strip 32, being of pliant material, is secured in place by simply inserting the tongue 38 along one edge into the corresponding pocket 35 of the retaining strip 3|, and then using a suitable tool to slightly reduce the arc of the strip 32 and allow the opposite tongue 38 to be pressed into place in the opposite recess 36. To facilitate the insertion of the strip 32, it is preferably provided with an internal channel 39, which gives the strip greater flexibility, and accommodates the fastening screws 16.
