Abstract

Abstract A detachable wheel trim for a vehicle wheel, having anchorage hooks for attachment to the wheel, operable from the external side of the trim. In one form three anchorage hooks are connected to a triangular arrangement of three resilient steel links fitting over a triangular cam connected to a rotary knob on the external surface of the trim, so that by rotating the knob and the cam the three links are bent outwardly to cause a resilient inward force to be applied to each hook, alternatively the three links may be combined into a continuous hoop, and the rotary triangular cam may be replaced by an axially movable cam. Two or more pairs of parallel links may be used instead of a triangular system and in place of a cam the links may be operated by levers connected to a rotary or axially movable central shaft connected to the external knob.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 105 words
A wheel trim including a cover member and anchorage means for holding the trim in position on a wheel, the anchorage means including a number of generally chordal resilient links interconnecting gripping members arranged to engage anchorage surfaces on the wheel, and non-circular rotary cam means mounted inside and centrally of the cover member, rotatably from outside the cover member between locking and non-locking positions, and shaped to cammingly engage the chordal links, whereby on rotation of the cam means the links are distorted to apply radial forCes to the gripping member, the links being adapted to retain the cam means in the locking position.
Claim 2
Dependent Claim 105 words
A wheel trim including a cover member and anchorage means for holding the trim in position on a wheel, the anchorage means including a number of generally chordal resilient links interconnecting gripping members arranged to engage anchorage surfaces on the wheel, and non-circular rotary cam means mounted inside and centrally of the cover member, rotatably from outside the cover member between locking and non-locking positions, and shaped to cammingly engage the chordal links, whereby on rotation of the cam means the links are distorted to apply radial forCes to the gripping member, the links being adapted to retain the cam means in the locking position.
Claim 3
Dependent Claim 18 words
A wheel trim according to claim 1, in which the anchorage means is separable from the cover member.
Claim 4
Dependent Claim 14 words
A wheel trim according to claim 1, in which the radial forces are inwards.
Claim 5
Dependent Claim 14 words
A wheel trim according to claim 1, in which the radial forces are outwards.
Claim 6
Dependent Claim 18 words
A wheel trim according to claim 1, in which the gripping members are integrally formed with the links.
Claim 7
Dependent Claim 22 words
A wheel trim according to claim 1, in which the gripping members are formed as separate members and attached to said links.
Claim 8
Dependent Claim 33 words
A wheel trim according to claim 1, in which the cam means is rigid with said cover member which rotates therewith when the cam means is turned between the locking and non-locking positions.
