A slide rail assembly including a first rail, a second rail, a third rail, a first supporting device, and at least one supporting member is provided. The first rail includes a first end portion and a second end portion that are opposite to each other. The second rail is longitudinally movable relative to the first rail. The third rail is longitudinally movable relative to the second rail. The first supporting device exceeds the first end portion of the first rail for a predetermined longitudinal distance. The at least one supporting member is arranged on one of the second rail and the first supporting device.

A drawer slide may include features for installation of the drawer slide to a cabinet and/or features for withdrawing rails of the drawer slide from one another. The features for installation of the drawer slide may include offset surfaces in a web of a rail, for example allowing for clearance for mounting hardware, and/or openings allowing for various positioning of the rail on a cabinet. The features for withdrawing rails from one another may include a moveable disconnect lever allowing for release of a catch of a rail, and/or a moveable hook.

A pullout guide comprises a stationary guide rail which can be fixed to a body, a middle rail which is movably held on the guide rail via first rolling elements arranged in a first rolling element cage, a running rail which is movably held on the middle rail via second rolling elements arranged in a second rolling element cage, and an opening on the middle rail for a support element, which, in a retracted position of the pullout guide, supports the running rail on the guide rail, the support element being mounted on the middle rail such that it can be lowered. In this case, the opening for the support element can be passed over by at least one second rolling element. This allows the support of the running rail to be optimized.

A movable coffee capsule storage rack includes a rack body for storage of coffee capsules. A first bracket is fixed to the bottom of the rack body, a first caster is rotatably connected to the first bracket through a first rotating shaft, a second bracket is disposed adjacent to the support leg, a second caster is connected to a second end of the second bracket, and when the second bracket is driven to rotate by the handle to drive the second caster to move down to hold up the support leg, the rack body is entirely supported by the first caster and the second caster and realizes free sliding. With the structure of the present disclosure, the storage rack is allowed to be switched quickly between the fixed state and the moving state through the movement of the second caster, the structure is simple, and the operation is convenient.

A drawer slide may include features for installation of the drawer slide to a cabinet and/or features for withdrawing rails of the drawer slide from one another. The features for installation of the drawer slide may include offset surfaces in a web of a rail, for example allowing for clearance for mounting hardware, and/or openings allowing for various positioning of the rail on a cabinet. The features for withdrawing rails from one another may include a moveable disconnect lever allowing for release of a catch of a rail, and/or a moveable hook.

A pull-out guide for drawers or the like comprising a fixed guide part fastenable to the body of a piece of furniture, a movable guide part fixable to a drawer or the like, an intermediate guide part between the fixed guide part and the movable guide part, wherein at least one first sliding carriage is interposed between the fixed guide part and the intermediate guide part and at least one second carriage is interposed between the movable guide part and the intermediate guide part; means of synchronizing the pull-out guide is further provided which comprise at least one synchronization element arranged on the intermediate guide part and contoured to functionally connect the fixed guide part and the movable guide part to each other during the pull-out or retraction movement of the pull-out guide.

A server chassis includes an outer case including a plurality of outer shells and an insertion space. The outer shell has an inner wall, and an outer rail structure is disposed on the inner wall of the outer shell. The outer rail structures including an outer rail-plate, an outer-rail and a set of ball slide rail. A chassis body is slidably coupled to the insertion space. The chassis body includes inner shells and an accommodating space. An inner rail structure includes an inner rail-plate, and the chassis body is capable of sliding with respect to the outer case through the inner rail-plate inserted in the outer-rail.

The invention relates to a drawer extraction guide with a corpus rail, a drawer rail, and a center rail and carriages arranged between them. It is provided that a synchronization device comprises at least a first and a second gear set with one or more synchronization wheels that are coupled with each other; that rolls a first synchronization wheel of the first gear set on one of the rails, on a component attached to the rail, on one of the carriages, or on an element attached to the carriage; that rolls a synchronization wheel of the second gear set on a further rail, on an element attached to a further rail, on a further carriage, or on an element attached to a further carriage; the synchronization device comprising a transfer member that is linearly and freely adjustable relative to the corpus rail, the center rail, the drawer rail, and the gear sets; and that one synchronization wheel of the first and the second gear set each roll on the transfer member. The invention allows for a compact configuration of a drawer extraction guide that is synchronized in its movement.
