Mich., a corporation of New Jersey Application May 26,

3 Claims.

The present invention relates to a supporting base and more particularly to a base which is especially adapted for supporting chairs, tables or other pieces of furniture.

The primary objects of the instant invention are to provide a supporting base of the general character above indicated which is noiseless in use; to provide such a base which though unsecured, cannot be readily inadvertently slid upon its supporting floor; and, to provide such a base which is efficient in use, attractive in appearance and economical in manufacture.

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

Figure 1 is a fragmentary top plan View of the base, the chair or table supporting column or pedestal thereof being shown in section; Figure 2 is a fragmentary elevational view thereof, certain parts being broken away and shown in section on line 2-2 of Figure 1;

Figure 3 is an enlarged sectional view on line 3-3 of Figure 1;

Figure 4 is a fragmentary perspective view of a portion of the underside of the supporting base, the meeting end portions of its resilient tubular shoe being removed from their annular groove to show the dowel connection between these end portions; and

Figure 5 is a sectional view on line 55 of Figure 1 showing the resilient shoe and its dowel connected meeting ends seated within the annular groove of the under sideof the supporting base.

Referring then to this drawing, in which like parts of the structure shown are designated by the same numerals in the several views, the supporting base is here shown as hollow, making for reduced weight and economy, and comprises a conical shell l0 having an upper sleeve portion H adapted to receive a supporting column or pedestal I2 for supporting a chair, table or the like.

This base is further provided with a depending marginal bifurcated flange l3 forming an annular groove I4 between its outer or peripheral leg and its inner marginal leg.

A resilient shoe l5, preferably of tubular rub- 1937, Serial No. 144,797

ber of normally greater cross-sectional diameter than the width of the groove [4, is compressed within this groove and is tensionally retained therein by its frictional engagement with the sides of the groove. This resilient shoe I5 extends completely around the base within its groove I4 and its meeting ends are preferably secured together by means of a dowel l6 which may have a slight curvature to conform to the curvature of the annular groove l4, all as best 10 shown in Figures 4 and 5.

It will thus be seen that the resilient shoe provides a noiseless cushioning effect for the article of furniture when it is moved from place to place and the frictional grip of the rubber shoe on the floor prevents accidental slippage of the supporting base.

While but one specific embodiment of the 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. A supporting base provided with a groove adjacent its periphery and within its under side, and a hollow tubular resilient element seated within said groove and projecting below the under side of the base.

2. A supporting base provided with a groove adjacent its periphery and within its under side, and a tubular resilient element of normally greater cross-sectional diameter than the width of said groove inserted and tensionally retained within said groove and projecting below the under side of said base.

3. A supporting base provided with an annular groove adjacent its periphery and within its under side, a tubular resilient element of normally greater cross-sectional diameter than the width of said groove inserted and tensionally retained within said groove and projecting below the under side of said base, and a dowel inserted within the opposite meeting ends of the tubular resilient element.
