  • Patent number: 6754934
    Abstract: A furniture cap or glide that is secured to a leg of an article of furniture, wherein the cap or glide defines an axis and has a lower surface and a sidewall spaced from the axis. The lower surface has a plurality of inner protrusions, a plurality of outer protrusions, and a series of connectors extending therefrom. The outer protrusions extend from the lower surface a first predetermined distance. The inner protrusions extend from the lower surface a second predetermined distance, which is smaller than the first predetermined distance. The connectors extend between and interconnect the some of the inner and outer protrusions, and extend from the lower surface a third predetermined distance. Initially, the outer protrusions engage the floor surface but, as the cap wears from use, the inner and outer protrusions simultaneously engage the floor surface, and thereby provide objective visual indication that the cap has worn a first amount.
