Abstract
A protective foot device for mounting on a piece of furniture to prevent movement of the furniture, such as the base, and to minimize marring of the floor or the furniture base is disclosed. The foot device has a portion that includes both an inner surface and an outside surface. The outside surface comes in contact with the floor, and the inside surface can have a plurality of longitudinal strips, which include longitudinal strip contact surfaces to contact and grip the furniture. The device also has end sections to permit the mounting and the removal of the device on the furniture and to prohibit excess rotation of the device.

A dual durometer protective foot device for axially mounting on a tubular floor contacting member of a piece of furniture, said foot device comprising:
- a generally cylindrically shaped body portion of a first durometer material having an inner surface and terminating in two end sections defining an axially extending gap, and a second durometer material extending inwardly from the inner surface of said first durometer material and having an inner diameter slightly smaller than the outer diameter of the tubular floor contacting member, said second durometer material restricting rotational and axial movement of said foot device with respect to the floor contacting member when said foot device is mounted thereon, said second durometer material only being positioned close to one of said end sections such that stress in said body portion due to deformation thereof when mounted on the tubular floor contacting member does not crack said body portion causing failure thereof.
A dual durometer protective foot device for axially mounting on a tubular floor contacting member of a piece of furniture, said foot device comprising:
- a generally cylindrically shaped body portion of a first durometer material having an inner surface and terminating in two end sections defining an axially extending gap, said inner surface having an inner diameter of said body portion substantially the same as the outer diameter of the tubular floor contacting member, each end section having an outwardly extending portion for assisting in the mounting and removing of said device from the tubular member and for limiting rotation of said device with respect to the tubular member, two longitudinally extending strips of a second durometer material integral with said body portion extending radially inwardly from said inner surface restricting rotational and axial movement of said foot device with respect to the floor contacting member when said foot device is mounted thereon, each of said strips being positioned close to one of said end sections such that stress in said body portion due to deformation thereof when mounted on the tubular floor contacting member does not crack said body portion causing failure thereof.
In combination, a piece of furniture having a seat and a frame including a tubular floor contacting member, a dual durometer protective foot device axially mounted on said tubular floor contacting member, said dual durometer foot device including a generally cylindrically shaped body portion of a first durometer material having an inner surface and terminating in two end sections defining an axially extending gap, said end sections being thicker than said body portion, and a second durometer material extending inwardly from the inner surface of said first durometer material and having an inner diameter slightly smaller than the outer diameter of the tubular floor contacting member, said second durometer material restricting rotational and axial movement of said foot device with respect to the floor contacting member when said foot device is mounted thereon, said second durometer material only being positioned close to one of said end sections such that stress in said body portion due to deformation thereof when mounted on the tubular floor contacting member does not crack said body portion causing failure thereof.
