A quick-release device comprising:
- a tubular structure adapted to extend through a first tube of a fork and having a first threaded end adapted to be mounted to a second tube of the fork, a flange radially extending from a second end of the tubular structure, the flange including indentations on an outer periphery thereof;
- a ring sleeved on the tubular structure and selectively axially engageable to the flange, the ring including an axially extending skirt, the skirt comprising bosses on an inner periphery thereof configured to engage the indentations of the flange, the skirt further comprising stubs on an outer periphery thereof;
- a sleeve axially connected to the ring, the sleeve comprising a centrally defined through hole and a flange radially extending from an inner periphery of the through hole to define an inner hole, wherein the flange divides the through hole in the sleeve into a first section and a second section, wherein the first section comprises ditches on an inner periphery thereof configured to engage the stubs on the outer periphery of the skirt, the sleeve further comprising a protrusion extending axially from and edge of the second section of the sleeve opposite to the ring;
- a spring compressively disposed in the first section of the through hole in the sleeve, the spring having two opposite ends respectively abutting against the second end of the tubular structure and the flange of the sleeve;
- a shaft co-axially connected to the second end of the tubular structure, the shaft having a flange radially extending therefrom to divide the shaft into a first portion and a second portion, wherein the first portion is connected to the second end of the tubular structure and the second portion extends through the inner hole in the sleeve;
- a washer received in the second section of the through hole in the sleeve and abutting the flange of the sleeve, a through hole centrally defined in the washer to allow the second portion of the shaft to extend through the washer;
- a pivot mounted to a distal end of the second portion of the shaft;
- and
- a lever pivotally mounted onto the pivot, the lever including a handle having a pair of ears formed on one end of the handle and abutting the washer, each ear having a pivot hole defined therein for rotatably receiving two opposite ends of the pivot, and a cam-shaped raised portion formed on one side thereof, the handle further comprising a trough near the pair of ears;
- wherein when the handle is pivoted such that the raised portions of the ears face away from the washer, the protrusion is received in the trough and the bosses of the ring are engaged with the indentations on the flange of the tubular structure such that rotating the lever about the axis of the tubular structure rotates the sleeve, the ring, and the tubular structure, thereby threadingly engaging the first end of the tubular structure into the second tube of the fork;
- and
- wherein when the handle is pivoted such that the raised portions of the ears face towards the washer, the sleeve is pushed against the spring such that the ring abuts the first tube of the fork.
