Abstract
Abstract Marker devices are disclosed in the form of reflex reflectors or the like, for attachment to the spokes of bicycle wheels or the like. In several embodiments, the marker device includes a marker member having seat means for receiving one of the spokes, so that the marker member will be maintained in the desired orientation by the spoke. The marker member is preferably supplied with clamping means for clamping the seat means against the spoke. The length of the marker member is preferably at least twice the spacing between the adjacent spokes, so that the position of the marker member will be stabilized by engagement with the adjacent spokes on both sides of the spoke to which the marker member is secured. The seat means may comprise a groove, formed in the marker member, for receiving the spoke. The seat means may also comprise one or more wall elements on the marker member. In certain embodiments, the clamping means includes a clamping screw which is engageable with the spoke. In certain embodiments, the marker member comprises a pair of reflex reflector plates secured together back to back. In certain other embodiments, the clamping means may include a rotatable cam or eccentric, operable by a screw driver or a lever. In another embodiment, the clamping means may take the form of a wedge block, slidable into a locking position on the marker member.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
120 words
A retroreflective marker device for attachment to a wheel having a plurality of wire spokes spaced apart at predetermined intervals, said device comprising a retroreflective marker member having a boss projecting therefrom, said marker member having an opening extending into said boss with internally screw-threaded means in said opening, and a clamping screw movably received in said opening and engaged with said internally screw-threaded means, said boss having a locating groove therein disposed off center relative to said opening for receiving and retaining one wire spoke of said wheel, said clamping screw having a clamping head disposed opposite said groove for directly engaging said spoke and clamping said spoke into said groove to retain said marker member on said spoke.
Claim 2
Dependent Claim
120 words
A retroreflective marker device for attachment to a wheel having a plurality of wire spokes spaced apart at predetermined intervals, said device comprising a retroreflective marker member having a boss projecting therefrom, said marker member having an opening extending into said boss with internally screw-threaded means in said opening, and a clamping screw movably received in said opening and engaged with said internally screw-threaded means, said boss having a locating groove therein disposed off center relative to said opening for receiving and retaining one wire spoke of said wheel, said clamping screw having a clamping head disposed opposite said groove for directly engaging said spoke and clamping said spoke into said groove to retain said marker member on said spoke.
Claim 3
Dependent Claim
54 words
A marker device according to claim 1, in which said marker member includes a second groove aligned endwise with said locating groove for receiving and retaining an additional portion of said spoke spaced along said spoke from said locating groove for improving the stability with which said marker device is mounted on said spoke.
Claim 4
Dependent Claim
86 words
A marker device according to claim 2, in which said marker member includes a wall abutment extending from said marker member for engaging said spoke at a point spaced therealong from said locating groove, said wall abutment and said second groove being spaced in opposite directions along said spoke from said locating groove, said wall abutment and said screw being disposed on opposite sides of said spoke, said wall abutment producing further improvement in the stability of the mounting of said marker device on said spoke.
Claim 5
Dependent Claim
58 words
A marker device according to claim 1, including a wall abutment extending from said marker member for engaging said spoke at a point spaced therealong from said locating groove to improve the stability of the mounting of said marker device on said spoke, said wall abutment and said clamping screw being disposed on opposite sides of said spoke.
Claim 6
Dependent Claim
62 words
A marker device according to claim 1, in which said marker member comprises a pair of retroreflective plates secured together back to back, said internally threaded means comprising a noncircular nut mounted between said reflective plates for receiving said clamping screw, said retroreflective plates having complementary means forming a noncircular socket between said plates for receiving and retaining said nut against rotation.
Claim 7
Dependent Claim
267 words
A retroreflective marker device for attachment to a wheel having a plurality of wire spokes spaced apart at predetermined intervals, said device comprising a retroreflective marker member having a front surface with an opening extending into said member, said retroreflective marker device including internally screw threaded means in said opening, and a clamping screw having an externally threaded shank movably mounted in said opening and engaging said internally screw threaded means, said front surface of said retroreflective marker member being formed with first and second locating elements thereon for locating one spoke of the wheel to maintain a predetermined alignment between said member and the spoke, said first and second locating elements being spaced apart endwise and aligned endwise for engaging first and second different portions of said spoke at points spaced apart along said spoke, said clamping screw having a head on said shank for directly engaging said spoke for clamping said retroreflective marker member against said spoke, said shank of said clamping screw being engageable on one side thereof with one side portion of said spoke, said first and second locating elements including respective first and second wall elements engageable with the opposite side portions of said spoke to confine said spoke under said head of said screw and between said shank and said wall elements, said clamping screw being disposed at an intermediate point between said first and second wall elements to provide clamping engagement between said head of said screw and said spoke at an intermediate point therealong between the points of engagement of said spoke with said first and second wall elements.
