Abstract
Abstract A bicycle support comprises a socket to be secured to the horizontal rear fork members of a bicycle frame, a support arm having one end pivotally connected to said socket for tilting movement of the arm from a position of rest into operating position and held in one or the other of said positions by a tilting spring acting eccentrically on the arm with respect to its pivoting axis to urge the arm against an abutment on the socket, a spring counterbearing being associated with said pivotally connected end of the arm. The spring counterbearing is formed by an arched surface, for example by the surface of a ball lodged in a trough formed on the pivotally connected end of the support arm, or by a concave arched surface of the trough itself.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
A bicycle support having a socket adapted to be secured to the rear horizontal fork of a bicycle frame, and a support arm having one end pivotally mounted in said socket for movement of the arm from a position of rest to an operative position, the support arm being positively held in both positions against an abutment of the socket by means of a tilting spring acting eccentrically on the supporting arm with respect to its pivoting axis, wherein the improvement comprises spring counterbearing means constituted by an arched surface associated with said pivotally mounted end of the support arm and directly supporting one end of the tilting spring, said spring counterbearing means comprising a ball which is located in a trough of the support arm and engages the last coil of said spring end, said trough having a radius of curvature greater than the radius of the ball.
Claim 2
Dependent Claim
149 words
A bicycle support having a socket adapted to be secured to the rear horizontal fork of a bicycle frame, and a support arm having one end pivotally mounted in said socket for movement of the arm from a position of rest to an operative position, the support arm being positively held in both positions against an abutment of the socket by means of a tilting spring acting eccentrically on the supporting arm with respect to its pivoting axis, wherein the improvement comprises spring counterbearing means constituted by an arched surface associated with said pivotally mounted end of the support arm and directly supporting one end of the tilting spring, said spring counterbearing means comprising a ball which is located in a trough of the support arm and engages the last coil of said spring end, said trough having a radius of curvature greater than the radius of the ball.
Claim 3
Dependent Claim
18 words
A bicycle support according to claim 1, in which said ball is rigidly connected with the spring end.
Claim 4
Dependent Claim
178 words
A bicycle positively having a socket adapted to be secured to the rear horizontal fork of a bicycle frame, and a support arm having one end pivotally mounted in said socket for movement of the arm from a position of rest to an operative position, the support arm being positively held in Both positions against an abutment of the socket by means of a tilting spring having one end supported by first counterbearing means on said socket and the other end supported by second counterbearing means on said support arm and acting eccentrically on the support arm with respect to its pivoting axis, an improvement wherein said second counterbearing means comprises an inwardly curved surface on said pivotally mounted end of the support arm supporting said other end of the spring both for tilting and lateral movement with respect to said curved surface of the pivotally mounted end of the support arm, and a ball secured to said other end of the spring, said ball having a smaller radius than the radius of curvature of said curved surface.
Claim 5
Dependent Claim
178 words
A bicycle positively having a socket adapted to be secured to the rear horizontal fork of a bicycle frame, and a support arm having one end pivotally mounted in said socket for movement of the arm from a position of rest to an operative position, the support arm being positively held in Both positions against an abutment of the socket by means of a tilting spring having one end supported by first counterbearing means on said socket and the other end supported by second counterbearing means on said support arm and acting eccentrically on the support arm with respect to its pivoting axis, an improvement wherein said second counterbearing means comprises an inwardly curved surface on said pivotally mounted end of the support arm supporting said other end of the spring both for tilting and lateral movement with respect to said curved surface of the pivotally mounted end of the support arm, and a ball secured to said other end of the spring, said ball having a smaller radius than the radius of curvature of said curved surface.
