Voytech ABSTRACT: A support for a picnic table designed for easy assembly and disassembly for winter storage or for compact shipping, the support comprising a pair of opposed, inclined sheet metal legs of channel cross section, with the ends and intermediate section having portions of the bottom of the channel bent into the channel parallel with one another and the ground. The lower end provides a broad foot for the leg and the upper intermediate bent portions provide supports for braces connecting and securing together the pair of legs to form a rigid frame. The intermediate brace is a single piece which passes through both legs and functions at its protruding ends as a support for benches for the table.

TABLE SUPPORT This invention relates to supports for tables usually placed in picnic areas for outdoor use, and particularly to table supports which are readily assembled and disassembled for storage or shipment.

Supports for picnic tables are usually made of wood and are nailed or otherwise permanently secured to the table top and benches. Because of the rough treatment to which they are subjected, both from the user and the weather, such tables are generally made of heavy planks and wooden braces which, when nailed or secured together, form a heavy, solid permanent structure capable of being left outdoors. For longer life, however, it is desireable that such tables be moved indoors into a sheltered storage area. Furthermore, the mobility of the public and its desire to enjoy picnics at different areas makes it desirable to move such tables from place to place. Neither of these objectives is achieved by the tables heretofore generally available.

Inasmuch as the table top and the benches for a picnic table are flat and can readily be stored in and of themselves in a narrow or flat space, it is the supports for the table and benches which create a storage problem and which must be in some way modified to provide a means for achieving portability. It is, therefore, an object of this invention to provide a picnic table and a support therefor, the latter being sturdy but light and readily assembled as a unit and with the top and benches of the table.

As a more specific object, this invention has within its purview the provision of a metal leg for a picnic table, said leg being made from sheet steel bent to channel shape with lower, middle and upper bent-over sections of the bottom of the channel forming, respectively, apad for the leg and horizontal supports for the braces which hold the legs together.

These and other objects of this invention will become apparent from the following detailed description thereof when taken together with the accompanying drawings in which:

FIG. 1 is a fragmentary end elevation in perspective of an assembled table showing the legs of this invention;

FIGs. 2 and 3 are enlarged elevations in perspective of the table leg of FIG. 1 showing the inside and outside construction respectively of the leg;

FIG. 4 is a plan view on a less enlarged scale of a sheet metal blank notched and cut preparatory to bending to form a table leg; and

FIG. 5 is a side elevational view of a brace which is secured to the leg.

Referring now to the drawings for a detailed description of the preferred embodimentv shown therein, the table may comprise several planks of identical size, such as 2 inches X inches X 72 inches, for example, and shown at 10, 11 and 12; two benches 13, 14 which may also be planks of 2 inches X l0 inches X 72 inches size; four identical legs, only two, 15, and 16, being shown; an upper brace 17, and a lower brace 18 which extends through legs 15 and 16 to form the support for benches 13 and 14. Braces 17 and 18 are preferably lengths of 2 inches X 4 inches lumber.

It is contemplated that the planks l0- 14 will be secured to their respective supports by carriage bolts, using wing nuts to make it possible to assemble or disassemble the planks and their supports without the need of any tools. It is further contemplated that the legs and the braces 17,18 may remain assembled as a flat unit, there being two such units per table.

All four legs are identical and are comprised of galvanized sheet metal formed into channels for rigidity, each channel having substantially parallel sides 19 and 20, and a bottom 21. As shown in FIG. 4, the substantially rectangular blank of sheet metal is notched at the bottom of the sides as shown at 23 and 24 to form flanges 25,26. The bottom 27 is bent along line 28 into the channel, with flanges 25,26 bent parallel to the planes of sides 19,20. Flanges 25,26 are then spot welded or otherwise secured to the adjacent sides 19 and 20, and bottom 27 thus forms a pad for the leg.

The top is notched at 29 and 30 and the portion 37 between the notches is bent along line 31 into the channel parallel to pad 27 to form a horizontal support for brace 17. The upper ends 32,33 of sides 19 and 20 remain upright to provide means for securing brace 17 to the leg. The width of the channel between sides 19 and 20 is made substantially equal to the width of brace 17.

Approximately midway between the ends of the leg the bottom of the channel, as shown in FIG. 4, is fonned with a U- shaped slot 34, and the portion of the bottom within the U is bent along line 35 into the channel parallel with pad 27 to form a support 36 for brace 18. Inasmuch as brace 18 carries the weight of the people using benches 13 and 14. additional support for brace 18 is provided by a pair of identical gusset plates 38,39 FIGS. 2 and 5) which are located in the slot 34 between support 36 and each side 19 and 20. Said gusset plates are spot welded or otherwise secured to said sides. Each gusset plate is formed with alined holes 40, two of which are alined with holes 41 in the sides 19 and 20 to receive screws by which brace 18 is secured to each leg. Holes 41 and 42 are provided in supports 36 and 37, respectively, by which said supports are secured to braces 18 and 17, respectively.

It is contemplated that the table may not be sold completely assembled, but instead the legs may be purchased from one source, with instructions for purchasing the planks and braces from a lumber yard, and the bolts and screws from either the lumber yard or a hardware store. The purchaser will then assemble the table to the form shown in FIG. I, using bolts 43 (FIG. I) and wing nuts 44 for the planks, and wood screws for the legs and braces.

If desired, a central transverse brace 45, of 2 inches X 4 inches lumber may be provided to brace the table lengthwise and possibly as a foot rest. Similarly, if the table is to be unusually long, an additional pair of legs (not shown) may be provided at the center of the table.

When the table has once been assembled and it is desired to disassemble it for transporting and storing it, all of the planks are removed from the top and benches by removing the wing nuts 44 and taking out the bolts 43, leaving the legs and attached braces 17,18 as flat units to be transported and stored with the flat planks.

Although the table has been described as made from planks, the top can also be made from a single sheet of plywood, or from sheet metal suitably formed for rigidity, the metal being aluminum or galvanized sheet steel. Other modifications will suggest themselves to those skilled in the art.
