inna e STANDING BOARD.

Application filed Eovember The prime object of the presentinvention is to provide an article of manufacture of novel structure, and adapted to serve an entirely new purpose. 7

The new purpose is that of providing a yieldingly floatingly mounted platform or resiliently elevated and more or less oscillatory floor board for persons who have hitherto suffered great fatigue from being compelled to stand on or walk about a confined area for long periods, as harbors, housewives at the ironing board, attendants at automatic machines, and so forth. The novel structure involved is one which entirely eliminates fixed pivotal points of support for the floor board, while providing at the same time an exceedingly simple, inexpensive and satisfactory construction, and one which, having a very few parts, is so constructed that these parts may be readily assembled to set up the new standing board anywhere, or readily disassembled and compactly bundled to facilitate transportation and storage,

The inv ntion will be more clearly understood from the following description, when taken in connection with the accompanying drawing, showing one of the many possible embodiments of the invention as now preferred.

In this drawing:

Fig. l is a perspective view'of such embodiment; and

Fig. 2 is a side elevation, partially in section. 7

From amere inspection of this drawing, and before a detailed description thereof is given, it will be instantly seen that an article of manufacture is provided which is quite different in structure andin purpose from athletic spring-boards, exercisers, and the like, in which considerable latitude of movement is permitted between the resilient members of the understructure and the platform or equivalent Referring now to the details of such drawing, the platform of the present invention is indicated at 8, and constitutes an auxiliary floor board to act as the direct tread support of the standing person. By the expression floor board, of course, is meant a floor structure of any suitable kind; that is to say, not necessarily a single board as illustrated, or a board of the shape shown, since in the latter particular it will, of course, be understood that the outlines and dimensions of the floor structure will be varied according 22, 1922. Serial 1T0. 692,555.

to the intended usefor the new article,

Tnus, he member 8 would desirably be shaped in outline like a fraction of an annu. is, if de ,red for use at a barbers chair.

resnient elements which form the essential part, of the structure, in that they alone, and without any auxiliary pivoting or bracing means, serve to support the floor board resiliently floatingly, comprise a plurality of axially compressible vertical columns of any suitable material or construction, as columns of rubber. Preferably, however, such resilient elements comprise, as her shown, substantially vertical, cylindri'cally coiled compression or expansile springs, as indicated at 4:. The parts last mentioned will be hereinafter referred to as the interposed resilient members.

These interposed resilient members are received at their upper ends in suitable recesses on the underside of the floor board, and at their bottom ends in suitable recesses on the upper faces of separate blocks or foot boards 5. These blocks, like the floor board, are conveniently construct-ed of wood. In the aresent construction, where the interposec resilient members are the cylindrical coiled springs 4:, each recess in the floor board is cylindrical as indicated at 6, as is the recess in each block as indicated at 7; an important feature of the invention being that the depths and diameters of such recesses are so arranged, relative to the resilient characteristics of the springs and the tendency of the latter to increase the diameters of their top and bottom terminal coils on compression axially, as from the weight of the floor board or of the latter plus the weight of a person thereon, that the coils mentioned expand sufficiently within the recesses to grip the same frictionally and tightly and thus serve to lock the whole article together when assembled as shown in the drawing.

The ease of assembly and disassembly of the nine simple parts constituting the embodiment of the new article of manufacture just described, and the compact space within which the parts may be packed for transportation and storage after disassembly is so apparent from the drawing that it is not necessary to dilate thereon.

It will, of course, be appreciated that various changes may be made in the general form and arrangement of the parts described Without departing from the invention, and

cise details set forth, but consider ourselves at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claim.

We claim:

its a new article of manufacture, a' standing board adapted to be supported on a floor comprising a board of an area large enough to permit a person standing thereon to walk in various directions thereon and formed with recesses on its under face at the corners thereof, a plurality of foot members, each formed with a recess in its upper face, said foot members being adapted to rest loosely on a floor, and springs each having its ends in a recess 01: the board and in a recess of a foot member the diameter of the recesses being such with respect to the size or the springs that the springs will engage the walls of the recesses and be securely held therein by the expansion of the springs, the

recesses being of such a diameter and depth with respect to the springs that thelatter are held in the recesses by friction, said springs and foot members serving as legs for the board adapted to be readily applied to and removed from the board and When removed to be disconnected from each other.
