An elongate rail (2) for use in a sliding support assembly (1), the sliding support assembly comprising a slide member (3) slidable in a longitudinal direction relative to the elongate rail and first (4a) and second locating assemblies, the elongate rail comprising a channel section defined by a first web, a first flange, and a second flange; a first wall (7a); and a second wall; wherein the first flange and the first wall (7a) define a first channel for retaining the first locating assembly (4a) and the second flange and the second wall define a second channel for retaining the second locating assembly.

An embodiment of the present invention provides a sliding device comprising: a first rail member which is open at one side surface thereof; a second rail member which slides on the first rail member and is open at one side surface thereof; and ball members which are disposed between the first rail member and the second rail member such that at least three ball members are provided as seen in a cross section, wherein the first rail member and the second rail member are arranged to be engaged with each other through the open side surfaces.

The invention concerns a telescopic rail comprising a first rail element with two running surfaces, a second rail element with two running surfaces, at least one rolling body cage for positioning a plurality of rolling bodies. Such telescopic rails are found to suffer from the disadvantage that the rail elements and the rolling body cages all have to be designed to be moveable relative to each other. Accordingly, the invention proposes providing a telescopic rail in which the rolling body cage is secured to the first rail element so that the rolling bodies perform a sliding movement with respect to the running surfaces of the first rail element and the rolling bodies perform a sliding movement with respect to the running surfaces of the second rail element or roll on the running surfaces of the second rail element.

The present invention relates to a slide device in which retainers provided between an outer rail, an intermediate rail, and an inner rail are guided to be placed at right positions when a drawer is opened or closed, thereby inducing a smooth movements of the rails. According to the slide device of the present invention, openings (312a and 130a) are formed at least in a second retainer locking step (312) and a second retainer deviation prevention step (130), respectively.

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 present invention concerns a rolling body cage for a linear guide or telescopic rail having rail elements which are displaceable relative to each other, wherein the rolling body cage has at least one bottom portion extending in a longitudinal direction of the rolling body cage, side wall portions which are arranged parallel and which extend on mutually opposite sides of the bottom portion substantially perpendicularly therefrom and in which there are provided rolling body holding recesses for receiving and holding rolling bodies between the raceways of rail elements and at at least a first end of the rolling body cage a connecting bridge which extends between the side wall portions substantially perpendicularly thereto, wherein the bottom portion, the side wall portions and the connecting bridge are produced in one piece from a first plastic. It has been found that both abutment of the inner rail against the rolling body cage and also abutment of the rolling body cage against the end abutment of the outer rail can generate noise which is perceived to be annoying. Therefore an object of the present invention is to further reduce those abutment noises. To attain that object it is proposed according to the invention that a rolling body cage of the kind set forth in the opening part of this specification is provided, in which the connecting bridge at least on two mutually opposite end faces is surrounded by a damping element comprising a second plastic, wherein the second plastic is softer than the first plastic.

A three-section linkage drawer slides apparatus, includes an upper rail, a middle rail, a fixed rail, an upper linkage rack, and a lower linkage rack, wherein the middle rail is slidably connected to the fixed rail through the lower linkage rack, the upper rail is slidably connected to the middle rail through the upper linkage rack, the upper linkage rack and the lower linkage rack are of separate structures, the upper linkage rack is mounted between the middle rail and the upper rail after being assembled, and the lower linkage rack is mounted between the fixed rail and the middle rail after being assembled. The upper linkage rack and the lower linkage rack are configured as separate structures, the manufacturing process can thus be simplified, so the manufacturing cost is reduced.

A slide unit includes a fixed rail fixed to a main body, and provided with a first accommodation space, a movable rail connected to a drawer body to allow the drawer body to be pulled out from and pushed into the main body, provided with a second accommodation space, and configured to be movable with respect to the fixed rail, an inner rail configured such that a first end thereof is inserted in the first accommodation space and a second end thereof is inserted in the second accommodation space, so as to allow the movable rail to be slidable with respect to the fixed rail, and a plurality of slide balls inserted in the first accommodation space to be disposed between the fixed rail and the inner rail, and inserted in the second accommodation space to be disposed between the movable rail and the inner rail.

The present invention shows a telescopic rail having at least one inner, middle, and outer rail element, wherein the inner and outer rail elements are each longitudinally displaceably supported at the middle rail element over rolling members that are guided in a rolling member cage. Provision is made in accordance with a first aspect that the rail elements are mechanically force-coupled via a rail synchronization arrangement such that on a longitudinal displacement of the outer rail element with respect to the inner rail element, the middle rail element is longitudinally displaced with respect to both the inner rail element and the outer rail element. Provision is made in accordance with a second aspect that at least one rolling member cage, and preferably both rolling member cages, is/are mechanically force-coupled to at least one of the rail elements via a respective rolling member cage synchronization arrangement such that a longitudinal displacement of the middle rail element with respect to the inner or outer rail elements results in a longitudinal displacement of the corresponding rolling member cage with respect to the middle rail element.

The present invention relates to a slide device in which retainers provided between an outer rail, an intermediate rail, and an inner rail are guided to be placed at right positions when a drawer is opened or closed, thereby inducing a smooth movements of the rails. According to the slide device of the present invention, openings (312a and 130a) are formed at least in a second retainer locking step (312) and a second retainer deviation prevention step (130), respectively.
