Abstract
A bicycle signal device is disclosed which includes a mechanism to activate an attention-getting signal when the bicycle is in motion. The signal device is particularly useful both for safety and for amusement or attraction purposes and specifically can include an activator system of a pulley assembly driven by an axle of the bicycle. Linkages from the pulley assembly transfer motion to a signal such as a flag to move the flag in a predetermined pattern to readily attract attention.
Claims12
A signal device operative to move to provide indication of the underway movement of a pedalled vehicle which has a frame supported by at least one wheel disposed about an axle attached to the frame, comprising:
- signal means;
- signal attachment means supportable by the vehicle frame for carrying the signal means for movement in an oscillatory pattern within a plane substantially parallel to the axle of the wheel;
- and
- signal drive means connected to the signal attachment means for engaging a member of the pedalled vehicle rotatable when the pedalled vehicle is in motion to drive the signal means through the signal attachment means in said oscillatory pattern as a function of the movement of the rotatable member to provide indication of the underway movement of the pedalled vehicle by the oscillating signal means.
A signal device operative to move to provide indication of the underway movement of a bicycle which has a frame supported by two wheels at least one of which is disposed about an axle attached to the frame, comprising:
- signal means;
- signal attachment means supportable by the vehicle frame for carrying the signal means for movement in an oscillatory pattern within a plane substantially parallel to the wheel axle attached to the frame;
- and
- signal drive means connected to the signal attachment means for engaging a member of the bicycle rotatable when the bicycle is in motion to drive the signal means through the signal attachment means in said oscillatory pattern as a function of the movement of the rotatable member to provide indication of the underway movement of the bicycle by the oscillating signal means.
A method of oscillating a bicycle signal device in a direction at right angles to the direction of a moving bicycle to provide indication of the underway movement of the bicycle, comprising the steps of:
- rotating a wheel of the bicycle;
- coupling the bicycle wheel to drive a rotary drive member;
- converting the rotary motion of the bicycle wheel by said rotary drive member to pivotable motion by converter means;
- linking the converter means to an assembly engaging the signal device;
- and
- oscillating a bicycle signal device engaged with the assembly undergoing pivotal motion in a direction at right angles to the direction of the moving bicycle to provide indication of the underway movement of the bicycle.
