Claims10
A gear arrangement, comprising:
- a rack having a first end part and a second end part opposite to the first end part, a plurality of teeth being arranged between the first end part and the second end part;
- a gear having a plurality of teeth configured to be engaged with the plurality of teeth of the rack, the gear being configured to be detachable from the rack;
- and
- a flexible member arranged on the rack, the flexible member comprising an extended part and a flexible part, the extended part extending in a longitudinal direction away from a tooth adjacent to the first end part of the rack, the flexible part being connected to the extended part, and a space being defined by the tooth adjacent to the first end part of the rack, the extended part and the flexible part;
- wherein the flexible part and the extended part are connected to form a hook structure, and the space defined by the tooth adjacent to the first end part of the rack, the extended part and the flexible part is U-shaped;
- wherein the gear is rotated in response to an elastic force provided by the flexible part of the flexible member, such that a tip of one of the teeth of the gear passes through the space without engaging with the extended part of the flexible member.

A gear arrangement, applicable to a slide rail assembly, the gear arrangement comprising:
- a rack configured to be fixedly mounted to a first rail of the slide rail assembly, and arranged along a longitudinal direction of the first rail, the rack having a first end part and a second end part opposite to the first end part, a plurality of teeth being arranged between the first end part and the second end part;
- a gear configured to be rotatably mounted to a second rail of the slide rail assembly, the gear having a plurality of teeth configured to be engaged with the plurality of teeth of the rack;
- and
- a flexible member connected to the rack for providing an elastic force, the flexible member comprising an extended part and a flexible part, the extended part extending in a longitudinal direction away from a tooth adjacent to the first end part of the rack, the flexible part being connected to the extended part, and a space being defined by the tooth adjacent to the first end part of the rack, the extended part and the flexible part;
- wherein the flexible part and the extended part are connected to form a hook structure, and the space defined by the tooth adjacent to the first end part of the rack, the extended part and the flexible part is U-shaped;
- wherein the gear is configured to be detached from the first end part of the rack when the second rail is moved relative to the first rail to a predetermined open position along a first direction;
- wherein the flexible member is configured to rotate the gear to be engaged with the rack during a process of the second rail being moved relative to the first rail from the predetermined open position along a second direction;
- wherein the gear is rotated in response to the elastic force provided by the flexible part of the flexible member, such that a tip of one of the teeth of the gear passes through the space without engaging with the extended part of the flexible member.
