A slide rail assembly includes a first rail, a second rail, a first engagement element, and a second engagement element. The first rail includes a first blocking part. The second rail is movably connected to the first rail. The first and second engagement elements are connected to the second rail. When the second rail moves relative to the first rail toward a first position, the first engagement element abuts against the blocking part of the first rail. When the first engagement element is operatively detached from the blocking part of the first rail, the second rail to is able to move relative to the first rail toward a second position from the first position. When the second rail is located at the second position, at least part of the second engagement element is adjacent to the blocking part of the first rail.

A drawer slide having first and second rails interconnected by a center rail. The center rail includes a spool configured to provide half-speed travel of the center rail relative to the travel of the first rail. The drawer slide is configured for use with a drawer assembly having a drawer and a chassis. The drawer assembly further includes a radius limiter secured to the center rail. The radius limiter travels at half-speed relative to the drawer. The radius limiter also automatically rotates relative to the travel of the drawer. The chassis includes sides including threaded backing plates, and mounting brackets. The mounting brackets include tri-lobed holes for receipt of a reciprocally shaped washer and a fastener for mounting the brackets to the chassis sides.

A slide rail assembly includes a first rail; a second rail movable relative to the first rail; a third rail mounted between the first rail and the second rail; a first sliding auxiliary device movably arranged between the first rail and the third rail, the first sliding auxiliary device comprising at least one first rolling member and a first meshing feature, the least one first rolling member configured to facilitate the third rail to move relative to the first rail; a second sliding auxiliary device movably arranged between the third rail and the second rail, the second sliding auxiliary device comprising at least one second rolling member and a second meshing feature, the least one second rolling member configured to facilitate the second rail to move relative to the third rail; and a synchronizing member meshed between the first meshing feature and the second meshing feature.

A refrigerator appliance includes a drawer slide synchronizer with a first cable and a second cable. A first bearing is mounted to a first one of a pair of drawer slides, and a second bearing is mounted to a second one of the pair of drawer slides. The first and second cables contact the first bearing, and the first and second cables also contact the second bearing.

A slide rail assembly comprises a first rail, a second rail, a third rail, a blocking element and an engagement element. The first rail has a blocking part. The blocking element is connected to the second rail. When the second rail is located at a retrieve position relative to the first rail, and the engagement element is operatively connected to the blocking element for moving the blocking element from a first predetermined position to a second predetermined position relative to the second rail, only the third rail can move relative to the second rail when the slide rail assembly is extended along an extension direction, in order to adjust extension length of the slide rail assembly.

A sequential slide mechanism for household effects is provided. The slide mechanism comprises a lower extension member, an upper extension member and an intermediate extension member, said extension members having a longitudinal extension, said upper extension member having a cut-out facing the lower extension member. The lower extension member and upper extension member being slidable in relation to the intermediate extension member. An extension member connector is attached to the intermediate extension member, said extension member connector having a rear end and a front end. The extension member connector comprises a main body mounted on the intermediate extension member and a head at the front end, said head being connected to the body via an elastic extension arm. The head has a top glide surface and a lower glide surface. The head is in an upper extension member locking position when the lower glide surface slides upon the cabinet slide and a part of the head is positioned in the cut-out. The head is in an upper extension member free-running position when said top glide surface slides upon the upper extension member.

A pull-out system comprises at least two pull-out guides, each pull-out guide having a stationary rail and at least one rail that can be moved relative to the stationary rail, means for synchronizing the movement of the movable rails being provided, said means comprising at least one flexible deflector element for synchronization. In this way, the movement of wide or heavy pull-out units can be synchronized in a simple manner, producing little noise.

A pull-out guide for drawers has a carcass rail, a drawer rail, and a central rail which is moveably mounted between the carcass rail and the drawer rail. At least one carriage is mounted in a moveable manner between at least two rails of the pull-out guide. A synchronization apparatus avoids running faults of the pull-out guide, and the synchronization apparatus has at least one synchronization wheel which interacts firstly with the one carriage and secondly with a running surface which is arranged on one of the rails. The synchronization wheel is in the form of a gear with two pinions with different diameters. The first pinion and the second pinion are connected to one another in a rotationally fixed manner, wherein, when one pinion moves, the other pinion also moves.

A slide rail assembly includes a first rail; a second rail movable relative to the first rail; a third rail mounted between the first rail and the second rail; a first sliding auxiliary device movably arranged between the first rail and the third rail, the first sliding auxiliary device comprising at least one first rolling member and a first meshing feature, the least one first rolling member configured to facilitate the third rail to move relative to the first rail; a second sliding auxiliary device movably arranged between the third rail and the second rail, the second sliding auxiliary device comprising at least one second rolling member and a second meshing feature, the least one second rolling member configured to facilitate the second rail to move relative to the third rail; and a synchronizing member meshed between the first meshing feature and the second meshing feature.
