Abstract
Abstract This invention provides a reflector adapted to be mounted on the spokes of a spokewise bicycle wheel or the like, such reflector including a plate-like reflector body having reflective surfaces each provided with reflective zones capable of reflecting incident light in generally parallel relation thereto. This reflector further comprises a through hole relative to said reflective surfaces, a nut portion which is coaxially movable in the through hole, a hook member, a bolt portion affixed to said nut portion, a fixing means and a rotation-restraining means. The hook member is integrally formed with one end face of said nut portion and extends therefrom in the axial direction. The bolt portion is provided for firmly pressing a spoke against the inside face of said hook member. The fixing means is provided for retaining the bolt portion on its opposite side through the through hole in a state where the spoke is firmly pressed against the inside face of the hook member and the spoke is in abutting engagement with the reflector.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
233 words
A reflector for a wheel including a plurality of spokes, said reflector including a plate-like reflector body having reflective surfaces each provided with reflective zones capable of reflecting incident light in generally parallel relation thereto, the improvements comprising a through hole in said reflector body, a nut portion which is coaxially movable in the through hole, a hook member formed integrally with one end face of said nut portion and extending therefrom in the axial direction, a bolt portion coacting with said nut portion and adapted to firmly press a spoke against the inside face of said hook member by virtue of the extremity of said bolt portion, a fixing means for retaining the bolt portion on its opposite side through said through hole in a state where the spoke is firmly pressed against the inside face of said hook member and the spoke is in abutting engagement with reflector, said fixing means including the bolt portion and a spring washer between the head of the bolt portion and the reflector body, and a rotation-restraining means for preventing rotation of said plate-like reflector body relative to the spokes, said rotation-restraining means comprising a groove in the reflector body, said spokes being inclined with respect to a plane through the wheel at a predetermined angle, and the axis of said through hole being perpendicular to said spoke to which the reflector body is secured.
Claim 2
Dependent Claim
233 words
A reflector for a wheel including a plurality of spokes, said reflector including a plate-like reflector body having reflective surfaces each provided with reflective zones capable of reflecting incident light in generally parallel relation thereto, the improvements comprising a through hole in said reflector body, a nut portion which is coaxially movable in the through hole, a hook member formed integrally with one end face of said nut portion and extending therefrom in the axial direction, a bolt portion coacting with said nut portion and adapted to firmly press a spoke against the inside face of said hook member by virtue of the extremity of said bolt portion, a fixing means for retaining the bolt portion on its opposite side through said through hole in a state where the spoke is firmly pressed against the inside face of said hook member and the spoke is in abutting engagement with reflector, said fixing means including the bolt portion and a spring washer between the head of the bolt portion and the reflector body, and a rotation-restraining means for preventing rotation of said plate-like reflector body relative to the spokes, said rotation-restraining means comprising a groove in the reflector body, said spokes being inclined with respect to a plane through the wheel at a predetermined angle, and the axis of said through hole being perpendicular to said spoke to which the reflector body is secured.
Claim 3
Dependent Claim
51 words
A reflector for a spokewise wheel as claimed in claim 1, in which said through hole comprises an enlarged diameter portion and a reduced diameter portion, said enlarged diameter portion permitting the nut portion to be generally coaxially movable and said reduced diameter portion permitting the nut portion to be immovable.
Claim 4
Dependent Claim
55 words
A reflector for a spokewise wheel as claimed in claim 1 in which the rotation-restraining means is a groove provided in a reflective surface and said groove is inclined at said predetermined angle, such that when the reflector is mounted on said spoke, the reflective surfaces are held perpendicularly to said plane through the wheel.
