Abstract
Abstract A device adapted for automatically retreating a side stand of a motorcycle when the motorcycle is started to drive is disclosed, which includes a spring normally urging the side stand in a direction of being deflected towards a retreated position; a lock member for retaining the side stand in a service position; a rotary member having a projection thereon and adapted to rotate when the motorcycle is started to run; a lever pivotally supported by a pin mounted on the body of the motorcycle and adapted to project within the passage of rotation of the projection; and a cable or rod interconnecting said lock member and said lever, such that, in association with the movement of said lever, caused by the rotation of the projection, in a direction to be retracted from the passage of rotation of the projection, said lock member is allowed to release the side stand.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
91 words
A device for turning a pivoted side stand of a motorcycle from a service position to a retreated position, comprising means for urging the side stand in a direction towards said retreated position; a first lever member adapted to be shifted between a release position and a lock position, said first lever member including a lock member adapted for retaining the side stand in said service position when the first lever member is in said lock position; means for urging the first lever member in a direction towards said lock position;
Claim 2
Independent Claim
91 words
A device for turning a pivoted side stand of a motorcycle from a service position to a retreated position, comprising means for urging the side stand in a direction towards said retreated position; a first lever member adapted to be shifted between a release position and a lock position, said first lever member including a lock member adapted for retaining the side stand in said service position when the first lever member is in said lock position; means for urging the first lever member in a direction towards said lock position;
Claim 3
Dependent Claim
162 words
stopper means connected to the side stand for retaining the first lever member in said release position when the side stand is positioned in said retreated position; a projection member rigidly provided on a rotary member of the motorcycle for rotation therewith; and a second lever member adapted to be shifted between a contact position at which the second lever member is positioned within the passage of rotation of the projection member and a retracted position at which the second lever member is not brought into contact with the rotating projection member, said first and second lever members being interconnected with each other through a connecting means such that shifting of the second lever member to said retracted position due to the rotation of the projection member results in shifting of the first lever member to said release position whereas shifting of the first lever member to said lock position results in shifting of the second lever member to said contact position.
Claim 4
Dependent Claim
162 words
stopper means connected to the side stand for retaining the first lever member in said release position when the side stand is positioned in said retreated position; a projection member rigidly provided on a rotary member of the motorcycle for rotation therewith; and a second lever member adapted to be shifted between a contact position at which the second lever member is positioned within the passage of rotation of the projection member and a retracted position at which the second lever member is not brought into contact with the rotating projection member, said first and second lever members being interconnected with each other through a connecting means such that shifting of the second lever member to said retracted position due to the rotation of the projection member results in shifting of the first lever member to said release position whereas shifting of the first lever member to said lock position results in shifting of the second lever member to said contact position.
Claim 5
Dependent Claim
27 words
The device as defined in claim 1, wherein said side stand is pivotally supported by a pin on a bracket attached to the body of the motorcycle.
Claim 6
Dependent Claim
31 words
The device as defined in claim 2, wherein said side stand urging means is a spring member connected at one end to the side stand and another end to the bracket.
Claim 7
Dependent Claim
38 words
The device as defined in claim 1, wherein the side stand has a lock pin adapted to be engaged with the lock member of the first lever member when the first lever member is in said lock position.
Claim 8
Dependent Claim
15 words
The device as defined in claim 4, wherein the stopper means is said lock pin.
Claim 9
Dependent Claim
18 words
The device as defined in claim 1, wherein said first lever member urging means is a spring member.
Claim 10
Dependent Claim
23 words
The device as defined in claim 1, wherein said rotary member is a sprocket mounted on an output shaft of a gearing mechanism.
Claim 11
Dependent Claim
22 words
The device as defined in claim 1, wherein said rotary member is a sprocket provided on a rear wheel of the motorcycle.
Claim 12
Dependent Claim
17 words
The device as defined in claim 1, wherein said rotary member is a hub of a wheel.
Claim 13
Dependent Claim
16 words
The device as defined in claim 1, further comprising a resilient cap covering said projection member.
Claim 14
Dependent Claim
59 words
The device as defined in claim 1, wherein said second lever member is pivotally supported by a pin on the body of the motorcycle and has a cam face adapted for engaging with the projection member such that rotation of the projection member permits the second lever member to be turned from said contact position to said retracted position.
Claim 15
Dependent Claim
45 words
The device as defined in claim 11, wherein said cam face has a protrusion to minimize a range of rotation angle of the pin provided on the rotation member, within which range the second lever member is failed to be positioned in said contact position.
Claim 16
Dependent Claim
15 words
The device as defined in claim 1, wherein said connecting means is a Bowden wire.
Claim 17
Dependent Claim
14 words
The device as defined in claim 1, wherein said connecting means is a rod.
Claim 18
Dependent Claim
31 words
The device as defined in claim 1, wherein said first lever member includes a manual lever for manually turning said first lever member from said lock position to said release position.
