Abstract
Abstract This invention relates to a floor preserving shoe of resilient material and of substantially channel-shape for closely fitting about the foot portion of a piece of furniture, such as a platform rocker. The bottom surface of the shoe is preferably concave across the width so that the weight of the furniture will flatten the curvature and in so doing the sidewalls of the shoe will more firmly engage said foot portion.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
115 words
A shoe for supporting the foot portions of platform rockers and the like, comprising an elongated, substantially channel shaped resilient element having a base portion and integral sidewall portions which define a longitudinal, substantially rectangular groove for tightly fitting the sides of one of said foot portions, said shoe having a concave base in a transverSe direction throughout the entire length so that as pressure is exerted by the weight of the furniture on the bottom of said groove, said concave surface becomes flattened to correspond to the flat surface of the floor and said integral sidewalls will be automatically bent inwardly so as to more tightly grip the sidewall surfaces of said foot portion.
Claim 2
Dependent Claim
115 words
A shoe for supporting the foot portions of platform rockers and the like, comprising an elongated, substantially channel shaped resilient element having a base portion and integral sidewall portions which define a longitudinal, substantially rectangular groove for tightly fitting the sides of one of said foot portions, said shoe having a concave base in a transverSe direction throughout the entire length so that as pressure is exerted by the weight of the furniture on the bottom of said groove, said concave surface becomes flattened to correspond to the flat surface of the floor and said integral sidewalls will be automatically bent inwardly so as to more tightly grip the sidewall surfaces of said foot portion.
Claim 3
Dependent Claim
47 words
A shoe as recited in claim 1 together with integral protuberances at the top ends of said sidewalls of the shoe which are in confronting relationship and overhang the sides of said groove, so as to hook onto or more tightly engage sidewalls of said foot portion.
Claim 4
Dependent Claim
26 words
A shoe as recited in claim 1 which is unattached to said foot portions and is normally in a flat plane for resting on the floor.
Claim 5
