7 Claims.

The present invention relates to supporting legs and more particularly to a tubular leg and its foot assembly.

lhe primary objects of the instant invention are to provide a leg and foot assembly for supporting portable desks and chairs; to provide such a structure which is rigid and sturdy in construction; to provide such a structure which may be readily and conveniently assembled; and, to provide such a structure which is economical in manufacture.

An illustrative embodiment of the invention is shown in the accompanying drawing, wherein:-

Figure 1 is a fragmentary perspective view of the tubular leg construction and its foot assemy;

Figure 2 is a sectional View thereof on line 22 of Figure 1; and

Figure 3 is an enlarged sectional view on line 33 of Figure 2.

Referring then to the drawing wherein. like parts of the construction shown are all designated by the same numerals in the several views, a pair of spaced blocks l0, here shown as metal castings forming supporting feet II for a desk, chair or the like, are each provided with a portion l2 projecting horizontally inwardly toward the other portion and each having a portion l3 projecting vertically therefrom.

The opposite ends of a horizontally disposed tubular member 4 fixedly embrace a horizontally projecting portion E2 of each block l0 and a pair of tubular supporting legs l5 each have an end thereof fixedly embracing a vertically projecting portion it of each block I!) and whose opposite ends are turned inwardly toward each other, all as best shown in Figure 1.

A centrally disposed tubular member it having a horizontally disposed portion and a vertically disposed portion lying interjacent the inner ends of the tubular supporting legs I5, is fixedly secured to the inner ends of the supporting legs in any suitable manner as by brazing and caps ll of rubber, steel or other suitable material are respectively stretched or pressed over the feet I I of each block.

It will thus be seen that the tubular leg and foot assembly of the structure herein shown and described is rigid and sturdy in construction, may be readily and conveniently assembled and is economical in manufacture and while but one specific embodiment of this invention has been herein shown and described, it will be understood that certain details of the construction shown may be altered or omitted Without departing from the spirit of the invention as the same is defined by the following claims.

I claim:

1. In a construction of the class described, a pair of spaced blocks forming supporting feet for a chair or desk, each having a portion projecting horizontally toward the other portion and each having a portion projecting vertically therefrom, a horizontally disposed tubular member whose opposite ends each fixedly embrace a horizontally projecting portion of a block, and a pair of tubular supporting legs each having an end thereof fixedly embracing a vertically projecting portion of a block.

2. In a construction of the class described, a pair of spaced blocks forming supporting feet for a chair or desk, each having a portion projecting horizontally toward the other portion and each having a portion projecting vertically therefrom, a horizontally disposed tubular member whose opposite ends each fixedly embrace a horizontally projecting portion of a block, and a pair of tubular supporting legs each having an end thereof fixedly embracing a vertically projecting portion of a block and whose opposite ends are each fixedly secured adjacent opposite sides of a centrally disposed member.

3. In a construction of the class described, a pair of spaced blocks forming supporting feet for a chair or desk, each having a portion projecting horizontally toward the other portion and each having a portion projecting vertically therefrom, a horizontally disposed tubular member whose opposite ends each fixedly embrace a horizontally projecting portion of a block, a pair of tubular supporting legs each having an end thereof fixedly embracing a vertically projecting portion of a block, and a floor engaging cap for each block.

5. In a construction of the class described, a pair of spaced blocks forming supporting feet for a chair or desk, each having a portion projecting horizontally toward the other portion and each having a portion projecting vertically therefrom, a horizontally disposed tubular member whose opposite ends each fixedly embrace a horizontally projecting portion of a block, a pair of tubular supporting legs each having an end thereof fixedly embracing a vertically projecting portion of a block and Whose opposite ends are each turned inwardly toward the other, and a centrally disposed member having a horizontally disposed portion and a vertically disposed portion Whose vertically diposed portion lies interjacent the inner ends of the tubular supporting legs and to which ends said portion is fixedly secured.

6. In a construction of the class described, a pair of spaced blocks forming supporting feet for a chair or desk, each having a portion projecting horizontally toward the other portion and each having a portion projecting vertically therefrom, a horizontally disposed tubular member whose opposite ends each fixedly embrace a horizontally projecting portion of a block, a pair of tubular supporting legs each having an end thereof fixedly embracing a vertically projecting portion of a block and whose opposite ends are each turned inwardly toward the other, a centrally disposed member having a horizontally disposed portion and a vertically disposed portion Whose vertically disposed portion lies interjacent the inner ends of the tubular supporting legs and to which ends said portion is fixedly secured, and a floor engaging cap for each block.

7. In a construction of the class described, a pair of spaced blocks forming supporting feet for a chair or desk, each having a portion projecting inwardly toward the other portion and each having a, portion projecting upwardly therefrom, a member whose opposite ends each fixedly embrace an inwardly projecting portion of a block, and a pair of supporting legs each having an end thereof fixedly embracing an upwardly projecting portion of a block.
