Abstract
A housing having a telescopingly extendible and retractable leg is carried by the frame of a motorcycle. A camming mechanism which drives the leg is secured to a reversible motor through a limited torque coupling whereby the extension of the leg is automatically terminated upon firm contact with the ground. Switching circuitry provides that the motor is manually actuated by the operator of the vehicle.
Claims6
A stand system especially adapted for use in combination with a motorcycle for automatically compensating for irregularities of the support surface to hold the motorcycle in a substantially upright position, said stand system comprising:
- (A) a housing securable to the motorcycle;
- (B) a leg extensively carried by said housing and having a free end for contacting said support surface;
- (C) selectively reversible drive means carried by said housing, said drive means transmitting a maximum drive force of a value which is less than the force required to lift the motorcycle from the support surface;
- (D) cam means responsive to the drive force of said drive means for alternately moving said leg in an extending direction and in a retracting direction;
- (E) said drive means including:
- 1. a reversible d-c motor carried by said housing;
- a. a first contact assembly section having a common terminal connected to a first electrical side of said reversible d-c motor;
- b. a second contact assembly section having a common terminal connected to a second electrical side of said d-c motor;
- c. first terminals of each of said first and second contact assembly sections being connected to a voltage source;
- and
- d. second terminals of each of said first and second contact assembly sections being selectively connected to motorcycle ground potential;
- and
- 2.
