A slide rail assembly includes a first rail, a second rail, a first locking mechanism, and a second locking mechanism. The second rail can be displaced with respect to the first rail. The first locking mechanism and the second locking mechanism are arranged at two different portions of the second rail respectively and are configured to lock the second rail at two predetermined extended positions respectively. The first locking mechanism and the second locking mechanism can be operated so that the second rail is no longer locked by the locking mechanisms and can be retracted with respect to the first rail.

A slide rail assembly includes a first rail, a second rail, a first locking device and a second locking device. The first rail includes a blocking part. The first locking device is arranged on the second rail and configured to lock the blocking part of the first rail when the second rail is moved to a first predetermined position relative to the first rail, such that the slide rail assembly has a first extension length. The second locking device is arranged on the second rail and configured to lock the blocking part of the first rail when the second rail is moved to a second predetermined position relative to the first rail, such that the slide rail assembly has a second extension length.

A carried object is applied to a rack system. The rack system includes a rack. The rack includes a plurality of posts. The carried object includes a first side wall and a second side wall. Each of the first side wall and the second side wall has a front end portion and a rear end portion. Wherein, an engaging hole is arranged on at least one of the first side wall and the second side wall. A fastening member is arranged at one of the first side wall and the second side wall. The fastening member has a blocking portion extended out of the engaging hole. When the carried object is moved from a first position to a second position, position of a blocking section of the blocking portion of the fastening member is corresponding to one of the plurality of posts of the rack.

A linear sliding structure of a laptop keyboard and cover case includes: a base member, a moving member, a sliding holder, a first resisting member, a second resisting member, and a ball. The ball is arranged in an accommodation portion of the sliding holder, such that two sides of the sliding holder where the ball is arranged come into contact with the base member and the moving member. The first resisting member and the second resisting member are respectively arranged at two ends of the base member to provide a resistance of an end position when the moving member undergoes a linear displacement. By way of the sliding holder where the ball is arranged, the linear displacement of the moving member extending toward one end is provided. A structure convenient for opening and closing is provided for the keyboard or the cover case.

A shelving system (11) and a bracket (10) for a shelving system comprising, the bracket (10) comprising a first end portion (19), an intermediate portion (18) and second end portion (20). The intermediate portion (18) comprises a flexible wall portion being moveable from an open position, in which the flexile wall portion is planar, to a closed position, in which the flexible wall portion is arcuate. In the closed position, the flexible wall portion can wrap around a portion of a post (14) and the first and second end portions (19, 20) engage to form a connector (32) engageable with an end of a rail (16) for supporting drawers.

A gear arrangement includes a rack, a gear and a flexible member. The rack includes a plurality of teeth. The gear is configured to be engaged with the rack through the teeth. The flexible member is adjacent to an end of the rack. The flexible member is configured to rotate the gear.
