Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
100 words
A multi-piece flooring-edge finisher comprising at least three components, including a first component which consists of friction insert and a base member, and two components which are edge pieces, wherein the edge pieces and the base member of said first component have interlocking complementary shapes facilitating connection between them in a manner such that in use of the finisher the friction insert is exposed but the base member is concealed from view by the edge pieces, said three components when connected forming a substantially rigid coherent structure, and said three components being supported directly on a floor when in use.
Claim 2
Dependent Claim
100 words
A multi-piece flooring-edge finisher comprising at least three components, including a first component which consists of friction insert and a base member, and two components which are edge pieces, wherein the edge pieces and the base member of said first component have interlocking complementary shapes facilitating connection between them in a manner such that in use of the finisher the friction insert is exposed but the base member is concealed from view by the edge pieces, said three components when connected forming a substantially rigid coherent structure, and said three components being supported directly on a floor when in use.
Claim 3
Dependent Claim
33 words
An edge-finisher according to claim 1 in which the underside of the edge finisher, which is in contact with a floor when in use, takes the form of a substantially continuous support surface.
Claim 4
Dependent Claim
34 words
An edge finisher according to claim 1, wherein one of the edge pieces extends in a plane away from the plane of the friction insert at a suitable angle to form a step nosing.
Claim 5
Dependent Claim
19 words
An edge finisher according to claim 1 in which said first component is a co-extrusion of two different materials.
Claim 6
Dependent Claim
29 words
An edge finisher according to claim 1 in which said base member is of a metal such as aluminium, and the edge pieces are of rubber or plastics material.
Claim 7
Dependent Claim
24 words
An edge finisher according to claim 1 in which said base member is of rubber or plastics material and the edge piece of aluminium.
Claim 8
Dependent Claim
79 words
An edge finisher according to claim 1 in which in the first component the base member has a cross-sectional shape in the form of a shallow `T` having projections on the arms of the `T` and the edge pieces envelop the ends of the arms of the `T` and have portions extending beneath the arms of the `T` to the stem of the `T`, shaped to facilitate a snap--or slide--fitting connection between the edge pieces and the base member.
Claim 9
Dependent Claim
50 words
An edge finisher according to claim 7 wherein the edge finisher is a step nosing and the first component is asymmetric, the `T` cross-sectional shape of the base member having a longer arm on that side of the `T` which will be adjacent to the step edge when in use.
Claim 10
Dependent Claim
132 words
A multi-piece flooring-edge finisher comprising at least three components, including a first component which consists of friction insert and a base member, and two components which are edge pieces, wherein the edge pieces and the base member of said first component have interlocking complementary shapes facilitating connection between them in a manner such that in use of the finisher the friction insert is exposed but the base member is concealed from view by the edge pieces, said three components when connected forming a substantially rigid coherent structure, wherein one of the edge pieces extends in a plane away from the plane of the friction insert at a suitable angle to form a step nosing having an additional bracing block beneath that edge piece which, in use, will extend down the step riser.
Claim 11
Dependent Claim
132 words
A multi-piece flooring-edge finisher comprising at least three components, including a first component which consists of friction insert and a base member, and two components which are edge pieces, wherein the edge pieces and the base member of said first component have interlocking complementary shapes facilitating connection between them in a manner such that in use of the finisher the friction insert is exposed but the base member is concealed from view by the edge pieces, said three components when connected forming a substantially rigid coherent structure, wherein one of the edge pieces extends in a plane away from the plane of the friction insert at a suitable angle to form a step nosing having an additional bracing block beneath that edge piece which, in use, will extend down the step riser.
Claim 12
Dependent Claim
98 words
A multi-piece flooring-edge finisher comprising at least three components, including a first component which consists of friction insert and a base member, and two components which are edge pieces, wherein the edge pieces and the base member of said first component have interlocking complementary shapes facilitating connection between them in a manner such that in use of the finisher the friction insert is exposed but the base member is concealed from view by the edge pieces, said three components when connected forming a substantially rigid coherent structure and further comprising an edge piece which incorporates a carpet gripper.
Claim 13
Dependent Claim
98 words
A multi-piece flooring-edge finisher comprising at least three components, including a first component which consists of friction insert and a base member, and two components which are edge pieces, wherein the edge pieces and the base member of said first component have interlocking complementary shapes facilitating connection between them in a manner such that in use of the finisher the friction insert is exposed but the base member is concealed from view by the edge pieces, said three components when connected forming a substantially rigid coherent structure and further comprising an edge piece which incorporates a carpet gripper.
