Abstract
Abstract A hydraulic righting and kickstand device includes a pivotal connection to a centrally located lower frame of the motorcycle, an upper kickstand member extending downwardly toward the ground, a fluid actuated cylinder structurally connected to the upper kickstand member, a piston actuated rod actuated in the cylinder extending downwardly from the lower end of the cylinder, a foot member structurally connected to the piston rod and extending toward the ground to the support the cycle with fluid pressure being supplied to the cylinder extending the piston to right the motorcycle.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
127 words
A righting device used in combination with a kickstand device used to support a motorcycle on the ground at a tilted angle wherein the kickstand device is pivotally connected to the motorcycle proximate to the center of a lower frame of the cycle, comprising: (a) a fluid actuated cylinder structurally connected as an intermediate section of the kickstand between an upper kickstand connection pivotally connected to the motorcycle frame and a lower foot section of the kickstand to rest on the ground, (b) a piston rod in the cylinder extendable downwardly and structurally connected to the foot section, and (c) fluid pressure means to supply fluid pressure to the cylinder to force the piston rod downwardly with the foot section against the ground to right the motorcycle.
Claim 2
Dependent Claim
127 words
A righting device used in combination with a kickstand device used to support a motorcycle on the ground at a tilted angle wherein the kickstand device is pivotally connected to the motorcycle proximate to the center of a lower frame of the cycle, comprising: (a) a fluid actuated cylinder structurally connected as an intermediate section of the kickstand between an upper kickstand connection pivotally connected to the motorcycle frame and a lower foot section of the kickstand to rest on the ground, (b) a piston rod in the cylinder extendable downwardly and structurally connected to the foot section, and (c) fluid pressure means to supply fluid pressure to the cylinder to force the piston rod downwardly with the foot section against the ground to right the motorcycle.
Claim 3
Dependent Claim
45 words
The device of claim 1 wherein a cylinder spring means is placed is the fluid actuated cylinder to place a spring load on the cylinder when extended downwardly with fluid pressure to return the piston rod to starting position when the fluid pressure is released.
Claim 4
Dependent Claim
53 words
The device of claim 1 wherein the fluid actuated cylinder comprises two chambers, one chamber under fluid pressure to actuate the pistion rod forcing it to extend out of the cylinder and a second chamber which under fluid pressure forces the piston rod to return to his original position unextended from the cylinder.
Claim 5
Dependent Claim
44 words
The device of claim 1 which further comprises a pressure actuated switch which under pressure actuates the fluid pressure means to force extension of the piston rod and upon release allows fluid pressure release and return of the piston rod to its unextended position.
Claim 6
Dependent Claim
127 words
A righting device for a motorcycle pivotally connected to a centrally located lower frame of the motorcycle, comprising: (a) an upper kickstand member, (b) a pivot connection means to pivotally connect the upper end of the upper kickstand member to the lower frame of the motorcycle, (c) a fluid actuated cylinder structually connected to the lower end of the upper end of the kickstand member and extending downwardly generally in the direction of the ground for supporting the motorcycle, (d) a piston actuated rod actuated in the cylinder extendable downwardly from the lower end of the cylinder, (e) a foot member structurally connected to the rod and extending toward the ground for supporting the motorcycle and, (f) fluid pressure means to supply fluid pressure to the cylinder.
Claim 7
Dependent Claim
127 words
A righting device for a motorcycle pivotally connected to a centrally located lower frame of the motorcycle, comprising: (a) an upper kickstand member, (b) a pivot connection means to pivotally connect the upper end of the upper kickstand member to the lower frame of the motorcycle, (c) a fluid actuated cylinder structually connected to the lower end of the upper end of the kickstand member and extending downwardly generally in the direction of the ground for supporting the motorcycle, (d) a piston actuated rod actuated in the cylinder extendable downwardly from the lower end of the cylinder, (e) a foot member structurally connected to the rod and extending toward the ground for supporting the motorcycle and, (f) fluid pressure means to supply fluid pressure to the cylinder.
Claim 8
Dependent Claim
45 words
The device of claim 5 wherein a cylinder spring means is placed in the fluid ctuated cylinder to place a spring load on the cylinder when extended downwardly with fluid pressure to return the piston rod to starting position when the fluid pressure is released.
Claim 9
Dependent Claim
54 words
The device of claim 5 wherein the fluid actuated cylinder comprises two chamber, one chamber under fluid pressure to actuate the piston actuated rod forcing it to extend out of the cylinder and a second chamber which under fluid pressure forces the piston rod to return to his original position unextended from the cylinder.
Claim 10
Dependent Claim
46 words
The device of claim 5 which further comprises a pressure actuated switch which under pressure actuates the fluid pressure means to force extension of the piston actuated rod and upon release allows fluid pressure release and return of the piston actuated rod to its unextended position.
