LOU F. SINCLAIR United States Patent TABLE CONSTRUCTION Lou F. Sinclair, North Miami Beach, Fla., assignor to giltmore Mfg. Co., Miami, Fla., a corporation of l lorida Application March 23, 1959, Serial No. 801,121

5 Claims. (Cl. 311-114) This invention relates in general to table construction and more particularly to tables and other furniture and fixtures constructed for assembly with a screw driver only.

Tables prior to this invention usually were dependent upon a wide apron for securing the top and legs thereto or were encumbered with bracing of questionable rigidity and unsightly appearance together with relatively high cost of manufacture, and in the case of tables having nondemountable legs, required large and bulky shipping containers.

The present invention overcomes the above objections and disadvantages by the provision of a simple planar top member framed in a relatively narrow mitred ornamental frame with a novel corner support means adapted to retain the frame in rigid relation to the top and to rigidly retain demountable legs thereto by the use of simple, unobtrusive threaded screw fasteners, which construction is the principal object of the invention.

A further object of the invention is the provision of a rigidized corner plate for fastening the corner of a mitred frame and supporting a planar top member of uniform thickness therein.

2 v I A cylindrical boss 9 having internal threads 10 is cantrally extruded from the recess 8 as shown. The plate 7 includes a pair of divergent arms 11--11 having an included angle therebetween of 90 degrees. Threaded holes 1515 in the plate 7 are symmetrically positioned v as shown for the assembly of the aforementioned frame.

Another object of the invention is the provision of A a rigidized frame having mitred corners made from linear extruded metal having channels therein for retaining a table top member and a corner plate adapted to receive and rigidly hold de-mountable legs having screw means in one end thereof.

These and other objects and advantages in one embodiment of the invention are described and shown in the appended specification and drawings in which:

Fig. 1 is a perspective view of a typical table in reduced scale.

Fig. 2 is a fragmentary exploded view of the components in the table shown Fig. 1.

Fig. 3 is a fragmentary bottom view of one of the corners of the table shown Fig. 1.

Fig. 4 is a fragmentary view of a frame member shown Fig. 1.

Fig. 5 is an enlarged fragmentary elevation taken through section line 5-5, Fig. 1.

Referring to Fig. 1 a table having a top member 1 of uniform thickness is retained in a frame consisting of four lengths of rigid ornamental channels 2 mitred at both ends thereof as shown. A corner plate to be hereinafter described is adapted to secure said channels, support said top and engage legs 3 by screw means in the ends thereof.

Referring to Fig. 2 each channel 2 is preferably made from extruded metal of uniform cross section and having an internal configuration as shown in which a tongue 4 and lip 5 form a linear rectangular slot 18. The upper side of the channel forms a rectangular opening for retaining the edge of the top 1.

A corner plate 7 preferably stamped from flat sheet steel of uniform thickness has a circular recess formed therein for providing an offset surface 8 parallel thereto.

Referring to Fig. 3 each arm 11 is inserted in the slot 18 formed by projection 4 and lip 5 and the lower leg of the channel in the junction end portions of channels 2-2 as shown, with a portion of the lip 5 cut away in the channels as shown Fig. 4 providing for clearance of the body of plate 7.

A counter-sunk hole 16 is provided in the end portion of each channel for the insertion of screws 17-17 which are threaded into hole 15-15 in the plate 7. The vertical assembly of each corner of the table is illustrated in Fig. 5. The top 1 is snugly retained between the upstanding projections 12, 13 and 14 and the overhanging upper leg of the channel 2. Fig. 5 also illustrates the attachment of the legs to each corner of the table by means of a screw means 19 of each leg threaded into the boss 9 in each of the plates.

It is apparent that this construction lends itself to use of thin table tops of different thickness by providing corresponding projections 12, 13 and 14 of appropriate length.

It is also apparent that the corner structure is exceedingly rigid and resistant to stress by virtue of the lockedin engagementof arms 11-11 in channels 18 and by virtue of the rigidity of plate 7 due to the bracing effect of the circular depression therein which depression also provides clearance for the upstanding boss of sufficient length to include sufiicient threads to resist stripping.

It is now apparent that the construction above described is useful for framing windows, mirrows, cabinet doors and the like with the omission of the extruded boss 9.

It is to be noted that the above described construction is applicable to a wide variety of frame shapes, such as triangular or other polygons by using corner plates with arms made with corresponding included angles.

Certain other modifications in construction retaining the features above described are intended to come within the scope of the appended claims.

Having described my invention, I claim:

1. A table construction comprising a rectangular planar top of uniform thickness, a plate means at each corner of said top spaced in parallel relation to the under surface thereof, by a plurality of integral upturned projections including a pair of integral divergent retaining arms, four U shaped frame members having a pair of co-linear parallel channels therein of uniform cross section forming a frame for retaining said top by the outer edges thereof in one of said channels and for retaining said arms in the other of said channels at each side of the junctions of said members with said projections supporting said top in upper portion of the said first mentioned channel, screw means in one side of each said member engaged with each of said arms for securing said members in rigid relation.

2. The construction recited in claim 1 including a portion of each said plate offset therefrom forming a parallel surface including a threaded boss normal thereto, a table leg having screw means in the upper end thereof threaded in each said boss with the said end against each said parallel surface forming a table.

3. In a table construction of the character described a planar table top having a plurality of sides, a like plurality of frame members having like channel means therein for retaining the edges of said sides and like plurality of corner plates, a like plurality of table legs having screw means in the upper ends thereof, a corner plate having a pair of divergent arms for securing each of said members to said top at the junctions thereof, each of said pair of arms positioned in said channel means and secured to the end portion of each of said members at the said junctions, an offset portion in said plate having thread means therein for retaining and rigidlysupporting said legs threaded thereto.

4. 'In a table of the character described a corner construction comprising a corner portion of a planar table top having a predetermined divergent angle between the edges thereof, the junction portion of a pair of frame members having a pair of channels therein and retaining the said edges of said top in one of said channels, a corner plate having a pair of arms extending therefrom congruent to said angle with each of said arms projecting into said other channel in each of said members for securing said members at said junction, said plate having a plurality of spaced projections extending equi-distant from and normal thereto positioned against the under side of said top for supporting same in the upper portion of said first mentioned channel, screw means through each of said members threaded into said plate for locking said members together.

5. The construction recited in claim 4 including an oifset portion in said plate With an outer surface parallel thereto and having a central threaded boss therein for rigidizing said plate and retaining a table leg threaded therein.
