Carpet trim

Claim 2

A carpet-underfloor adaptor for an underfloor entrance unit which has a circular shaped cover plate, the adaptor comprising: a circular shaped head, a circular shaped wall and circular shaped base; said base having means for engaging the top surface of a cover plate whereby to mount the adaptor on the plate; said head being disposed above the peripheral edge of the base and including an outer flange and an inner flange, the outer flange extending outwardly in a direction away from the center of the base and being for use in extending over the edge of carpet installed on the floor for retaining and protecting the edge anD the inner flange extending inwardly in a direction toward the center of the base and being for use in extending over the edge of carpet installed on the cover for retaining and protecting the edge and in such position the head being exposed on the surface of the carpet whereby to be susceptible to receive a compressive load such as being stepped on by a foot, the load being in a direction to move or bend the head toward the base and the head being made of resilient material permitting the head to move or bend toward the base when receiving said compressive load and to return to unloaded position with the compressive load removed; said wall extending between the base and the head and around the peripheral edge of the base, the wall being formed with a plurality of side-by-side legs and being made of resilient material; and lower joint means connecting the bottom of each leg of the wall to the base and upper joint means connecting the top of each leg of the wall to the head, the upper joint means providing for compressive load on the head to be transferred to legs of the wall and said upper and lower joint means respectively holding the top and bottom of each leg whereby said resilient material of a leg provides for the leg to fold when subjected to said compressive load and to return to unloaded position with said load removed and said fold being characterized by that the mid-section of a leg is moved laterally and the portion of the leg above the mid-section extends over the portion of the leg below the mid-section with the top and bottom of the leg in substantial vertical alignment whereby said movement of the head toward the base is accomplished with substantially no lateral motion.

Claim 3

A carpet-underfloor adaptor for an underfloor entrance unit which has a rectangular shaped cover plate, the adaptor comprising: a rectangular shaped head, a rectangular shaped wall and a rectangular shaped base; said base having means for engaging the top surface of a cover plate whereby to mount the adaptor on the plate; said head being disposed above the peripheral edge of the base and having an outer flange and an inner flange, the outer flange extending outwardly in a direction away from the center of the base and being for use in extending over the edge of carpet installed on the floor for retaining and protecting the edge and the inner flange extending inwardly in a direction toward the center of the base and being for use in extending over an edge of carpet installed on the cover for retaining and protecting the edge and in such position a head being exposed on the surface of the carpet whereby to be susceptible to receive a compressive load such as being stepped on by a foot, the load being in a direction to move or bend the head toward the base and the head being formed of resilient material permitting the head to move or bend toward the base when receiving said compressive load and to return to unloaded position with the compressive load removed; said wall extending between the base and the head and around the peripheral edge of the base, the wall being formed with a plurality of serially spaced side-by-side legs and in each corner of the wall there being a pair of adjacent legs which are spaced apart sufficiently so that there is an open space at the corner and the wall being made of resilient material; and lower joint means connecting the bottom of each leg of the wall to the base and upper joint means connecting the top of each leg of the wall to the head, the upper joint means providing for compressive load on the head to be transferred to the legs of the wall and said upper and lower joint means respectively holding the top and bottom of each leg whereby said resilient material of a leg provides for the leg to fold when subjected to said compressive load and to return to unloaded position with said load removed and said fold being characterized by that the mid-section of a leg is moved laterally and the portion of the leg above the mid-sEction extends over the portion of the leg below the mid-section with the top and bottom of the leg in substantial vertical alignment whereby said movement of the head toward the base is accomplished with substantially no lateral motion.

Claim 4

A carpet-underfloor adaptor for an underfloor entrance unit which has a rectangular shaped cover plate, the adaptor comprising: a rectangular shaped head, a rectangular shaped wall and a rectangular shaped base; said base having means for engaging the top surface of a cover plate whereby to mount the adaptor on the plate; said head being disposed above the peripheral edge of the base and having an outer flange and an inner flange, the outer flange extending outwardly in a direction away from the center of the base and being for use in extending over the edge of carpet installed on the floor for retaining and protecting the edge and the inner flange extending inwardly in a direction toward the center of the base and being for use in extending over an edge of carpet installed on the cover for retaining and protecting the edge and in such position a head being exposed on the surface of the carpet whereby to be susceptible to receive a compressive load such as being stepped on by a foot, the load being in a direction to move or bend the head toward the base and the head being formed of resilient material permitting the head to move or bend toward the base when receiving said compressive load and to return to unloaded position with the compressive load removed; said wall extending between the base and the head and around the peripheral edge of the base, the wall being formed with a plurality of serially spaced side-by-side legs and in each corner of the wall there being a pair of adjacent legs which are spaced apart sufficiently so that there is an open space at the corner and the wall being made of resilient material; and lower joint means connecting the bottom of each leg of the wall to the base and upper joint means connecting the top of each leg of the wall to the head, the upper joint means providing for compressive load on the head to be transferred to the legs of the wall and said upper and lower joint means respectively holding the top and bottom of each leg whereby said resilient material of a leg provides for the leg to fold when subjected to said compressive load and to return to unloaded position with said load removed and said fold being characterized by that the mid-section of a leg is moved laterally and the portion of the leg above the mid-sEction extends over the portion of the leg below the mid-section with the top and bottom of the leg in substantial vertical alignment whereby said movement of the head toward the base is accomplished with substantially no lateral motion.
