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.

A slide rail assembly includes a first rail, a second rail, a third rail, a synchronization member and a fastening member. The third rail is movably mounted between the first and second rails. The synchronization member and the fastening member are movably mounted to the third rail. The synchronization member is configured to engage with the second rail, such that the second and third rails can be synchronously moved relative to the first rail along an opening direction. When the second and third rails are moved to a first predetermined position, the synchronization member is disengaged from the second rail. When the third rail is moved from the first predetermined position to a second predetermined position along the opening direction, the third rail is fastened to the first rail by the fastening member to prevent the third rail from being moved relative to the first rail along a retracted direction.

A slide rail device with an unlocking structure for a middle slide rail includes an outer slide rail mounted on a fixing member, and an inner slide rail mounted on a side wall of a movable member. The inner slide rail is coupled to the outer slide rail to enable a middle slide rail to be disposed between the outer slide rail and the inner slide rail. A ball bearing unit is disposed between the middle slide rail and the inner slide rail. A releasing element is movably disposed on the middle slide rail and arranged between the ball bearing unit and the elastic locking element. When the inner slide rail and the movable member are removed from the slide rail device, the releasing element is pushed by the ball bearing unit and pushes an elastic locking element to unlock the middle slide rail.

A drawer glide mechanism can include a first elongate guide member, a second elongate guide member, a ball bearing component, a v-notch socket, a release mechanism, and/or a roller support. The first elongate guide member can include a distal end that is configured to fit within an opening in the v-notch socket. The drawer glide mechanism can further include one or more floating members and fixed members. In some cases, the drawer glide mechanism includes a release member configured to facilitate separation of the first and second elongate guide members when actuated and to inhibit or prevent accidental separation of the first and second elongate guide members.

A supporting device for a rail member includes a first supporting frame and a second supporting frame. The first supporting frame has a first supporting means including a first supporting part and a second supporting part. A supporting passage is defined by the first supporting part and the second supporting part. The second supporting frame has a second supporting means including a third supporting part and a fourth supporting part. The first supporting means and the second supporting means are configured to support each other. A rail member is configured to be connected to one of the first supporting frame and the second supporting frame, the first supporting part is configured to support the third supporting part, and the second supporting part is configured to support the fourth supporting part. The first supporting part is spaced from and not directly connected to the second supporting part.

A supporting device for a rail member includes a first supporting frame and a second supporting frame. The first supporting frame has a first supporting means including a first supporting part and a second supporting part. A supporting passage is defined by the first supporting part and the second supporting part The second supporting frame has a second supporting means including a third supporting part and a fourth supporting part. The first supporting means and the second supporting means are configured to support each other. A rail member is configured to be connected to one of the first supporting frame and the second supporting frame. The first supporting part is configured to support the third supporting part, and the second supporting part is configured to support the fourth supporting part. The first supporting frame and the second supporting frame cooperatively define an enclosed space.

A supporting device includes a first supporting frame having a first supporting means including a first and a second supporting part, and a second supporting frame having a second supporting means including a third and a fourth supporting part. A supporting passage is defined by the first and the second supporting part. The first and the second supporting means are to support each other. A rail member is to be connected to one of the first and the second supporting frame. The first and the second supporting part are to support the third and the fourth supporting part, respectively. The first supporting frame further includes a first side wall connected to the first and the second supporting part. The first supporting part has a first portion extended from a first end of the first side wall to form a first angle therebetween. The first angle is a non-right angle.

A supporting device for a rail member includes a first supporting frame and a second supporting frame. The first supporting frame has a first supporting means including an upper element and a lower element. The upper element includes a first supporting part. The lower element includes a second supporting part. A supporting passage is defined by the upper element and the lower element. The second supporting frame has a second supporting means including a third supporting part, a fourth supporting part and a second side wall extendedly connected to the third supporting part and the fourth supporting part. The first supporting means and the second supporting means are configured to support each other. The upper element is spaced from and not directly connected to the lower element, and the upper element and the lower element are formed as two independent parts of the first supporting frame.

A drawer slide assembly includes first and second rails, a drawer frame member, a mounting device, and an inserting member. The second rail is longitudinally movable with respect to the first rail. The drawer frame member is connected to the second rail and includes a carrier and a drawer sidewall connected to the carrier. The mounting device is connected to the drawer frame member and/or the second rail and includes an engaging member and a guiding member. The engaging member has an engaging portion corresponding to the guiding member. The inserting member corresponds to the guiding member and can be inserted thereinto to displace the engaging member to an engaged position and, by engaging with the engaging portion, be mounted to the mounting device.

A furniture rotary system (100, 200, 300, 400, 500) for a piece of furniture (10, 20, 30, 40, 50) is provided. The furniture rotary system is forming a sliding rotary connection between a rotational member (120, 210, 320, 410, 520) and a stationary member (110, 220, 310, 420, 510), wherein said furniture rotary system (100, 200, 300, 400, 500) comprises at least one sliding surface (114, 214, 314, 414, 514) being coated with a lacquer comprising a resin, wherein said lacquer in turn is at least partly coated with a lipophilic composition coating to provide a slide layer with a lowered friction.
