Abstract
Abstract A stand device for a two-wheeled motorcycle having a pivotal member supported by a shaft supporting a motorcycle stand for pivotal movement, the pivotal member being capable of moving in pivotal movement independently of the motorcycle stand and including a tongue for moving the motorcycle stand from an operative position in which it is tilting forwardly to a neutral position as the pivotal member moves pivotally. A main spring is mounted between the upper portion of the pivotal member and the intermediate portion of the motorcycle stand, and the pivotal member is urged by the biasing force of an auxiliary spring so as to cause the motorcycle stand to return from its operative position to its neutral position.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
145 words
A stand device for a two-wheeled motorcycle including a body frame comprising: a. a stand pivotally supported by a bracket attached to said body frame of the motorcycle; b. a pivotal member capable of moving in pivotal movement about a point at which said stand is pivoted and including an upper portion above said point, said pivotal member moving in pivotal movement independently of said stand and having a portion which moves said stand from its operative position to its neutral position; c. a main spring mounted between the upper portion of said pivotal member and said stand; and d. an auxiliary spring mounted between the upper portion of said pivotal member and the bracket and adapted to urge by its biasing force the pivotal member to act in such a manner that the stand is restored from its operative position to its neutral position.
Claim 2
Dependent Claim
145 words
A stand device for a two-wheeled motorcycle including a body frame comprising: a. a stand pivotally supported by a bracket attached to said body frame of the motorcycle; b. a pivotal member capable of moving in pivotal movement about a point at which said stand is pivoted and including an upper portion above said point, said pivotal member moving in pivotal movement independently of said stand and having a portion which moves said stand from its operative position to its neutral position; c. a main spring mounted between the upper portion of said pivotal member and said stand; and d. an auxiliary spring mounted between the upper portion of said pivotal member and the bracket and adapted to urge by its biasing force the pivotal member to act in such a manner that the stand is restored from its operative position to its neutral position.
Claim 3
Dependent Claim
102 words
A stand device as claimed in claim 1, wherein said main spring includes an upper end connected to said upper portion of said pivotal member, with the position at which the upper end of said main spring is supported being set such that, when said pivotal member is caused by the auxiliary spring to be disposed at one limit of the range of its pivotal movement, the point at which said stand is pivoted is disposed on a line connecting the two positions at which both ends of the main spring are supported and the stand is brought to its neutral position.
Claim 4
Dependent Claim
96 words
A stand device as claimed in claim 1, wherein said stand includes an upper end portion in the form of a letter U and said pivotal member is disposed between two vertical portions of said U-shaped pivotal member, and wherein said portion of said pivotal member adapted to move said stand from its operative position to its neutral position comprises a tongue extending downwardly from the lower end of the pivotal member along the front of the horizontal portion of the U-shaped upper portion of the stand with respect to the longitudinal axis of the motorcycle.
Claim 5
Dependent Claim
32 words
A stand device as claimed in claim 3, wherein said tongue also performs the function of a stopper for setting one limit of the range of pivotal movement of said pivotal member.
