INVENTOR HOWARD J MARSCHAK ATTORNEY BASE PORTION OF A STAND OR THE LIKE BRIEF SUMMARY OF THE INVENTION One of the objects of this invention is to provide a base for a stand, which base is formed of a plurality of leg sections, each formed with a central portion having a pair of walls, with a leg radiating from the central portion and with the central portion having a pair of angled walls which taper so that the width of the walls increases progressively from the top towards the bottom to consume more material at the bottom than at the top, which draws or lifts the central or hub portion of the leg upward higher than the plane of the outer extremities of the legs.

Another object of this invention is to provide a stand having a base formed of two or four leg sections each integrally formed and provided with central portions which when assembled form a hub for receiving the upright with the hub raised above the outer ends of the legs.

Another object of this invention is to provide a base which is relatively inexpensive to manufacture, is easily set up, and which may be shipped as a compact unit requiring a minimum amount of shipping space.

Other objects will become apparent as this description progresses.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. l is an exploded view of one form of the invention utilizing two leg sections which when joined form a stand.

FIG. 2 is a top plan view of one of the leg sections for forming the base.

FIG. 3 is a side view of the leg section, positioned as it would be when in assembled relation to form the base for a stand and showing the central portion thereof raised above a floor or supporting surface.

FIG. 4 is a view of the leg section provided with a glider and leveling means, and

FIG. 5 is a reduced plan view showing a modification.

FIGS. 1-4

The two sections, shown in FIGS. 1, 2 and 3 and indicated by the numeral 10, which form the base are of identical construction. Each leg section has a central portion generally indicated at 12, shaped to form a generally L-shaped bend in plan view, comprising a pair of walls 14 and 16. Extending from each of the ends of the walls 14 and 16 is a leg 18 and 20 respectively. The legs extend perpendicular to the respective walls 14 and 16. As can best be seen in FIGS. 1 and 3, the walls 14 and 16 taper, i.e., the distance between the opposite ends of each of the walls, that is, from the central apex line 20 to the side bend lines 22 and 24 respectively at the top of the bend is less than the distance at the bottom, therefore, the width at the top of each wall, indicated by the lines aa is less than the width at the bottom, indicated by the lines b-b. The width of the walls increases progressively from the top to the bottom. The bends thus consume more material at the bottom along lines b-b than at the top along lines a-a This draws or lifts the center portion of the leg upward, as best shown in FIG. 3, and only the outer tips of the legs indicated at 18 and 20 will contact the floor or supporting surface 26 when the two sections are connected or assembled, as will be subsequently described. The two leg sectionsare made preferably of metal.

The top or upper edge of each leg inclines or slopes outwardly from the central portion towards the outer end or tip. The upper portion of each leg is bent at an obtuse angle to form a louver or rib 28 and 30 respectively, along the length of each leg to strengthen same. A rubber tip, not shown, may be secured on the outer or tip end of each leg, or a glider and leveling means, as shown in FIG. 4, may be used. This comprises a threaded stud 32 welded as at 34 to the underside of the tip of the leg and ball-shaped member 36 having an internally threaded bore 38 is secured to the stud so that the leg sections will rest on the four ball members 36. A pair of spaced holes 40 are formed at the apex or corner line of the central section. The ball is adjustable relative to the stud to provide the leveling means.

The upright portion of the stand comprises a tubular member 42 provided with a pair of spaced openings 44 which register with the openings 40 in the base. The two leg sections 10 may be shipped in a knocked down and nested condition, that is, unassembled in relation to each other and to the tubular upright. When it is desired to set same up as a base for a stand the two leg sections 10 are positioned as shown in FIG. 1, with their central portions 12 adjacent each other so that the two central portions form a cone-shaped and squareshaped hub 46 in plan when joined together.

The cone or square-shaped hub 46 receives the lower end of the tubular member 42 and after the openings 44 are aligned with the openings 40 a pair of threaded bolts 48 are inserted transversely to connect the two leg sections It) with the upright 42 and they are interlocked by wing nuts 50 or other type of nut at the opposite end of the bolts. When the two leg sections are interlocked with the upright there will be four legs forming the base, with each leg spaced from the other and with the central hub portion 46 raised from the supporting surface 26 to provide a firm support for the: stand.

FIG. 5

FIG. 5 is a top plan view of a modification in which the base of the stand is formed of four legs made of four separate sections instead of two as described in connection with FIG. 1 to 4. FIG. 5 shows two leg sections nested together to form the equivalent of one leg section 10 previously described.

In this connection there are two leg sections 52 and 54 which form one side of the stand. Twoother like leg sections are similarly joined to from the other side of the stand. Leg section 52 has a central portion forming two walls 56 and 57, formed identical to the central walls 14 and 16 and provided with a leg 58, similar to leg 18. The other leg section 54 has a central portion forming two walls 60 and 61, identical to walls 14 and 16, and a leg 62 identical to leg 20. The central walls have spaced openings similar to the openings 40.

In assembling the four sections the walls 60 and 61 are nested within the walls 56 and 57, as shown in FIG. 5, to form one side of the stand, with the other side similarly formed, and then the four sections are assembled with the upright 42 positioned in the central hub formed by the four leg sections.

What is claimed is:

1. A stand or the like comprising, a plurality of leg sections of identical shape and each having a central portion provided with angled walls attached to a vertical upright member and a pair of legs extending radially therefrom, each angled wall tapering and progressively increasing in width from the top to the bottom, whereby when the angled walls are attached to said vertical upright member the legs extend outwardly and downwardly.

2. A structure as set forth in claim l in which the stand is formed of four leg sections.

3. A structure as set forth in claim I. in which transversely extending openings are provided at the corners of the angled walls and in which the upright is provided with an opening registering with the wall openings, and a fastening member extending transversely through said openings for securing said members in assembled relationship.

4. A structure as set. forth in claim 1 in which the top of the legs incline downwardly from the center to their outer portions.

5. A structure as set forth in claim 2 in which each leg section has a central portion and a leg with a pair of central sections nested to form each side of the base.

6. A structure as set forth in claim 5 in which openings are provided at the corners of the angled walls and in which the upright is provided with an opening registering with the wall openings, and a fastening member extending transversely through said openings for securing said members in assembled relationship.

7. A structure as set forth in claim 1 in which gliders are attached to the outer ends of the legs.

8. A structure as set forth in claim 7 in which the glider comprises a ball member secured to a threaded stud and in which the ball member is adjustable relative to the threaded stud to provide for leveling the leg.

9. A structure as set forth in claim 1 in which the extremities of the legs have leveling means.
