Abstract
Abstract A safety device or warning signal for attachment to a two-wheeled vehicle, e.g. a bicycle, arranged to be attached to a section of the framework of the vehicle and to extend transversely from same in direction towards the off-side lane in a road, having a flexible and resilient joint and a warning or signal member at the free end portion of the transversely extending part.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
259 words
A signal-safety device for use on a bicycle-type vehicle for extending laterally therefrom and warning other vehicles to maintain a prescribed distance, said signal-safety device comprising; an elongated, substantially rigid element of a length defining a clear safe distance for passing vehicles; mounting means at one end of said element for mounting the rigid element in laterally-extending relationship from a frame member of the vehicle upon which the signal-safety device is to be used; a signal device at the other end of said rigid element for warning an oncoming vehicle of the presence of the vehicle upon which the signal-safety device is mounted and apprising the oncoming vehicle of the clear, safe distance at which to pass the signal-safety device; and a flexible, resilient joint means interposed between said rigid element and said mounting means so that the signal-safety device will yield when struck by an oncoming vehicle and will not damage the same nor the vehicle upon which it is mounted and will permit the signal-safety device to be folded along the frame of the vehicle upon which it is mounted to permit storage of the signal-safety device, said rigid element being tubular and said resilient joint means comprising a helical coil spring element telescoped into the tubular rigid element, said mounting means comprising a stud threaded into said coil spring element and a reverted, externally-threaded, U-shaped element for receiving a frame member of the vehicle transversely therethrough, and a nut element circumposed about said U-shaped element for clampingly engaging the transverse frame member in the U-shaped element.
Claim 2
Dependent Claim
259 words
A signal-safety device for use on a bicycle-type vehicle for extending laterally therefrom and warning other vehicles to maintain a prescribed distance, said signal-safety device comprising; an elongated, substantially rigid element of a length defining a clear safe distance for passing vehicles; mounting means at one end of said element for mounting the rigid element in laterally-extending relationship from a frame member of the vehicle upon which the signal-safety device is to be used; a signal device at the other end of said rigid element for warning an oncoming vehicle of the presence of the vehicle upon which the signal-safety device is mounted and apprising the oncoming vehicle of the clear, safe distance at which to pass the signal-safety device; and a flexible, resilient joint means interposed between said rigid element and said mounting means so that the signal-safety device will yield when struck by an oncoming vehicle and will not damage the same nor the vehicle upon which it is mounted and will permit the signal-safety device to be folded along the frame of the vehicle upon which it is mounted to permit storage of the signal-safety device, said rigid element being tubular and said resilient joint means comprising a helical coil spring element telescoped into the tubular rigid element, said mounting means comprising a stud threaded into said coil spring element and a reverted, externally-threaded, U-shaped element for receiving a frame member of the vehicle transversely therethrough, and a nut element circumposed about said U-shaped element for clampingly engaging the transverse frame member in the U-shaped element.
Claim 3
Dependent Claim
39 words
The structure as claimed in claim 1 in which said U-shaped element has opposed, divergent side portions for accommodating different diametered vehicle frame members and providing a wedging engagement with the frame member when engaged by the nut element.
Claim 4
Dependent Claim
37 words
The structure as claimed in claim 1 including a resilient member disposed about the exterior of the substantially rigid element and said helical coil spring and stud threaded therein for reinforcing and protecting the resilient joint means.
Claim 5
Dependent Claim
23 words
The structure as claimed in claim 1 in which said signal device comprises a flag-like element having a distinctive and readily visible color.
Claim 6
Dependent Claim
16 words
The structure as claimed in claim 4 in which said flag-like element comprises a light-reflective material.
Claim 7
Dependent Claim
50 words
The structure as claimed in claim 1 in which said rigid element includes a hook element projecting laterally from an intermediate portion thereof for removably engaging a rod-like portion of a vehicle frame member when the rigid rod element is folded into parallel relationship thereto about the resilient joint means.
Claim 8
Dependent Claim
55 words
The structure as claimed in claim 1 in which said stud being externally threaded and having an outer diameter slightly greater than the internal diameter of the helical coil spring element for expanding the coil spring in the tubular, rigid element and providing a rigid connection between the stud member and the rigid tubular element.
Claim 9
Dependent Claim
37 words
The structure as claimed in claim 7, in which a second resilient member is circumposed about the flexible, resilient joint means between the rigid element and said mounting means for reinforcing and protecting the resilient joint means.
