A drawer synchronous slide includes a fixed slide rail (1), a middle slide rail (2), and a movable slide rail (3) connected to each other slidably, wherein a synchronizing gear (8) is arranged on the middle slide rail (2), a first synchronizing rack (6) and a second synchronizing rack (7) arranged horizontally and oppositely are respectively fixed onto the movable slide rail (3) and the fixed slide rail (1), left and right sides of the synchronizing gear (8) are respectively meshed and work in conjunction with a tooth-shaped part of the first synchronizing rack (6) and a tooth-shaped part of the second synchronizing rack (7), an elastic part (61) is arranged on the first synchronizing rack (6), the tooth-shaped part of the first synchronizing rack (6) is elastically pressed towards the synchronizing gear (8) under the action of elastic stress of the elastic part (61).

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.

The present invention relates to the technical field of furniture and discloses a slide rail assembly which comprises a top rail, a middle rail and a bottom rail. The top rail and the middle rail slide relative to each other through a first rolling element, and the middle rail and the bottom rail slide relative to each other through a second rolling element. A first bending portion of the middle rail is inserted into a first cavity and a second bending portion is inserted into a second cavity. A gear is provided between a first serrated edge of a first bracket and a second serrated edge of a second bracket and meshes with the first and second serrated edges, so that the top rail, the middle rail and the bottom rail can be linked. The present invention also discloses a cabinet adopting the slide rail assembly.

A sliding element guide system for furniture is provided, including a cabinet unit rail, central rail, sliding element rail, and at least one carriage. The cabinet unit rail, central rail, and sliding element rail are mounted to be movable in relation to one another. The system also includes two identical synchronization wheels that synchronize movements of elements of the system. The two identical synchronization wheels are rotatably mounted on a vertically oriented central rail side wall and extend horizontally therefrom via a pin.

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.

Sliding element guide system for furniture including a cabinet unit rail, central rail, sliding element rail, and a carriage such that the cabinet unit rail, central rail, and sliding element rail are mounted so as to be movable in relation to one another. The system also includes synchronization means including a synchronization element to synchronize movements of elements of the system. Two identical synchronization elements are present on the central rail and are rotatably disposed on the central rail. The synchronization elements are disposed so as to be mutually opposite and mutually spaced apart on both sides of the central rail. The synchronization elements are configured on mutually opposite end sides of the central rail or on mutually opposite external sides of the central rail.
