Abstract

A combination antitheft—quick lock device for the wheels or saddle rod of a bicycle includes a lever connected to an eccentric and at least one rod having a threaded end for receiving a bearing washer and a nut. The eccentric bears upon and is rotationally linked to the bearing washer and to the threaded rod extending through the hub of the wheel. A guiding channel for at least one ball is formed as a blind channel in the lever, forming an obtuse angle relative to the longitudinal axis thereof. A bore is formed in the axis and opening into the channel and has a shoulder defining a widened recess. An eccentric reversible locking means includes a widened head configured for displacement in the widened recess and a rod guided by the channel and abutting the ball. A spring is disposed between the widened head and the bore shoulder.

Claims

1. An anti-theft—

quick lock—

device for bicycle parts, wheels and/or seat rod, the wheels being blocked on the front fork or on the rear seat stay by a fast locking system of a lever attached to an eccentric and at least one rod having a threaded end receiving a bearing washer and a nut, said eccentric bearing against and linked in rotation to said bearing washer and to said threaded rod extending through the hub of the bicycle wheel comprising;

a guiding channel configured to accommodate at least one ball, said guiding channel defining a blind channel in the lever at an obtuse angle with respect to to a longitudinal axis of said lever, said axis defining a bore opening at a first end in said guiding channel and at a second end directed towards an axis of rotation of said lever, having a shoulder forming a widened recess,

a reversible means for blocking the eccentric with respect to its pivot of the axis of rotation, said reversible blocking means comprising a mobile enlarged head disposed in the widened recess and a rod guided within the guiding channel and abutting the ball, a spring placed between the enlarged head and the shoulder of the bore maintaining said reversible blocking means on the pivot of the axis of rotation, wherein—

when the bicycle is in a horizontal position in which the bicycle is on its wheels and the eccentric is blocked, the device is in a clamped position in which the reversible blocking means is blocked and in which the head prohibits the eccentric from rotating about the pivot, and wherein when the bicycle is in a substantially vertical position, the lever displaces said reversible blocking means and, under the effect of gravity, said ball separates from the bore and the first end of said rod in the guiding channel releases the eccentric.

2. Device according to claim 1, wherein the enlarged head has a perpendicular milling on each of its free surfaces.

3. Device according to claim 1, wherein the guiding channel is closed by a part defining an interior surface in said guiding channel that is positioned slightly lower than the axis when the bicycle is on its wheels, the ball by gravity coming into contact with said interior surface.

4. Device according to claim 1, wherein the reversible blocking means defines an end that is inclined according to the axis of the duct.

5. Device according claim 1, wherein the nut has a smooth exterior geometry in the form of a dome.

6. Device according claim 1, further comprising a first and a second support washer, the first support washer interacting with the eccentric, the second support washer interacting with the nut, each of the first and second washers defining a protuberance that is housed between the fingers of the fork in order to prohibit rotation.

7. Device as claimed claim 1, wherein the nut defines a toothed surface that bears upon said second washer.

8. Device according to claim 1, wherein the lever is curved in such a way as to hug a clamping collar positioned on the seat rod, said collar having on its open portion two bores passing from the closing of the collar by the threaded rod, the second bore opposite the lever being tapped to accommodate the threaded portion of the rod.

9. Device according to claim 1, wherein the guiding channel for the ball emerges inside the fork of the eccentric.
