Abstract
Abstract A side-stand for a motorcycle wherein an auxiliary member is provided at one side of the side-stand in a length which stretches fairly beyond the contact surface of the side-stand when the motorcycle is set upright for running, whereby, even if a rider forgets to retract or level the side-stand, frictional contact between the bottom tip end of this auxiliary member and the ground surface causes the side-stand to be retracted automatically while running.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
118 words
A side-stand for a motorcycle which comprises in combination: a body of a motorcycle; a side-stand having a bent portion to be the contact surface with the ground surface, and movably fitted at one end part thereof to said motorcycle body; and an auxiliary member fitted to one side of said side-stand, said auxiliary member being such that, when the motorcycle is to be parked a part thereof is Bent or collapsed by the weight of the motorcycle body, and, when the motorcycle is set upright to start running, the collapsed part stretches downward by its own resiliency or by an external elastic force to protrude beyond the contact surface of said side-stand to face the ground surface.
Claim 2
Dependent Claim
118 words
A side-stand for a motorcycle which comprises in combination: a body of a motorcycle; a side-stand having a bent portion to be the contact surface with the ground surface, and movably fitted at one end part thereof to said motorcycle body; and an auxiliary member fitted to one side of said side-stand, said auxiliary member being such that, when the motorcycle is to be parked a part thereof is Bent or collapsed by the weight of the motorcycle body, and, when the motorcycle is set upright to start running, the collapsed part stretches downward by its own resiliency or by an external elastic force to protrude beyond the contact surface of said side-stand to face the ground surface.
Claim 3
Dependent Claim
43 words
The side-stand for a motorcycle as claimed in claim 1, wherein said auxiliary member is fitted inside the side-stand in a manner, in which it is joined with a telescopic lever to be extendible and retractible by means of a spring built therein.
Claim 4
Dependent Claim
81 words
The side-stand for a motorcycle as claimed in claim 1, wherein said auxiliary member is swingably fitted to said side-stand by means of a connecting structure which comprises a shaft secured to said side-stand in a direction generally transversed of the motorcycle body, a torsion spring provided therearound, a hub, a small projection provided on said hub, and a stopper provided on said side-stand which acts to collide with said small projection to stop further backward movement of said auxiliary member.
Claim 5
Dependent Claim
19 words
The side-stand for a motorcycle as claimed in claim 3, wherein said torsion spring is a rubber torsion spring.
Claim 6
Dependent Claim
22 words

Claim 7
Dependent Claim
27 words
The side-stand for a motorcycle as claimed in claim 3, wherein said torsion spring is a coil spring provided around the outer peripheral surface of said hub.
Claim 8
Dependent Claim
37 words
The side-stand for a motorcycle as claimed in claim 1, wherein said auxiliary member is swingably fitted at one end part thereof to one portion of said side-stand, and is oscillated by a separate, external spring force.
Claim 9
Dependent Claim
