GLIDER FOR FURNITURE LEGS Filed Nov. 15, 1931 Fig.1.
gwwntoz awn/new Patented Apr. 11, 1933 UNITED STATES PATNT HQE CLEMENT R. UHL, F TOLEDO, OHIO, ASSIGNOR TO THE TOLEDO METAL FURNITURE COM- I PANY, OF TOLEDO, OHIO, A CORPORATION OF OHIO GLIDER FOR FURNITURE LEGS Application filed November 13, 1931.
durable in its construction, and has its legreceiving socket sufiiciently pliant and elastic to permit engagement with legs having feet portions of different shapes and sizes. The device in addition to serving as a cushioned glider for a furniture leg, is also adapted to act sideways as a cushion buffer to prevent injury to parts against which it may be moved.
The invention is fully described in the following specification, and while inits broader aspect it is capable of embodiment in different forms, one embodiment thereof is illustrated in the accompanying drawing, in which Figure 1 is a side elevation of a device embodying the invention with a part in cen tral section. Fig. 2 is a top plan view thereof. Fig. 3 is a cross-section on the line 33 in Fig. 1. Fig. 4 is a top plan View of the glider plate member of the device, together with the means by which it is anchored in the yielding material of the top member. Figs. 4A and 4B are fragmentary views similar to that of Fig. 4, showing different forms of anchorage openings in the anchoring member. Fig. 5 is a section on the line 55 in Fig. 4, and Fig. 6 is an elevation of the lower end portion of one form of metal furniture leg, with a device embodying the invention positioned thereon and in central vertical section.
Referring to the drawing, 1 designates the cup member of a device embodying the invention, such member having a leg-receiving cavity 2 in its top and being formed of rubber, or other cushion material, which is preferably of an elastic nature.
Furniture legs of the metal type are usual- V provided with flanged feet portions 3, and the cup cavity 2 is of a shape and size to receive such feet and has its mouth normally 50 contracted relative to its bottom to Cause the Serial 110,574,703.
mouth wall to hug the leg above the flange of an engaged foot.
In order to provide the cup member with a hard smooth glider surface, awear and glider I plate 4, preferably of hardened steel, is attached to the bottom of said member with its side edge preferably terminating short of the side edge of the member, so that the latter provides a projecting side buffer surface for the plate. 8 The plate 4 is preferably of disc form and slightly bowed to present a convex surface to the floor, and is securely held in engagement with the cup member bottom by molding the material of the cup around and through por- '3 tions of an anchoring disc 5 attached to the inner side of the plate a by electric spot welding, or in any other suitable manner. The disc 5, which is substantially the same size as the plate 4, is dished to adapt its central por- 1' tion to seat on and be secured to the plate 4: centrally thereof and to cause its marginal edge portion or rim 6 to be spaced from the plate, with its major portion substantially parallel therewith, thus permitting the material of the cup to enter and fill the space between the plate 4 and rim 6. In order to form a more secure anchorage than would be accomplished by this alone, the rim 6 is provided therethrough with an annular seriesso of openings which are shown in Fig. 4 as in the form of apertures 7 and in Figs. 4A and 413 as in the form of notches 7 and 7 respectively. The cup material has interengaging connection with the disc through these '85 openings. It will be noted that the material of the cup is molded and vulcanized around the plate 4 and its anchor piece 5 to securely and intimately unite and connect the two, and. in such operation the plate 4 is preferably""o0 set into the cup material so that only its lower surface is exposed.
The side edge of the cup member preferably projects a suiiicient distance beyond the plate, edge to form a fairly heavy side buffer por tion 8, and the neck portion of the cup is sufficiently thinned to permit stretching when being applied to or removed from a leg.
It is apparent that I have provided a glider device for metal furniture legs, which is provided with a cup member of yielding material, such for instance as rubber, to enable it to be mounted on or removed from the lower end of a furniture leg, and particularly those of metal having feet portions, and that the bottom surface of the yielding cup member is provided with a glider plate which is securely anchored in the material of the cup member and is suitable to withstand consider- 10 able wear and permit a free sliding movement of the device over a surface on which it rests.
Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:
15 1. A device of the class described, comprising a cup member of soft vulcanized rubber having the side Wall of its cavity portion thinned and inwardly directed to form a restricted mouth, a glider plate anchored in 2 the base portion of the cup member with its bottom surface exposed and forming a portion of the bottom surface of the cup member, said cup member having a portion surrounding the edge of the plate which is l heavier than the side wall portion of the cavity to provide the cup member with a side bufier portion between the plate and the relatively thin side wall portion of the cup cavity.
Q9 2. In a device of the class described, comprising a member of yielding material adapted to be attached to the lower end of a furniture leg, a slightly convexed glider plate secured to and forming the central portion 3 of the bottom surface of said member, and an anchorage member of dished-form secured at its central portion to the central top surface portion of said plate and having its rim portion laterally spaced from the rim por- Q tion of the plate and adapted to have interengaging connection with the material of said member to securely anchor it therein.
3. A device of the class described, com prising a cup member of yielding material for receiving and engaging the lower end of a furniture leg, the bottom portion of said member being relatively heavy and having a side edge portion extending beyondthe side wall of its leg-receiving portion to form a 5 yielding buffer shoulder, a glider plate of slightly outwardly convexed form secured in said bottom portion with its outer edge in inwardly spaced relation to said buffer shoulder, and an anchorage member of dishedform secured at its central portion to the central top surface portion of said plate and having its rim portion laterally spaced from the rim portion of the plate and adapted to have interengaging connection with the material of said member to securely anchor it therein.
In testimony whereof I have hereunto signed my name to this specification.
