A piece of furniture, such as a lectern, has a shell with an opening. A rack for electronic equipment is mounted within the shell. The rack can be slid between a stowed position in which the rack is entirely within the furniture and an access position in which the rack extends through the opening and is partially outside the shell.

In order to provide drawer guide for guiding a drawer which is extendable out of a carcass in an extension direction and which is of stable configuration and in particular enables the reliable guidance of drawers with an unfavorable width-depth ration, it is proposed that the drawer guide to comprises a guidance unit configured as a vertical guidance unit and a guidance unit configured as a lateral guidance unit, wherein the two guidance units each comprise a carcass-side guidance rail and a drawer-side guidance unit mounted on rolling bodies and wherein the two guidance units are coupled to each other by means of a coupling device.

A device for fixing a push element, in particular a drawer box to a rail of a pull-out guide, the device comprising a clamping mechanism with a receptacle for a holding part and a device for depth adjustment for the drawer box, wherein the device for depth adjustment comprises a stop that can be adjusted either on or in the receptacle. As a result, a precise orientation of the drawer box to a pull-out guide can be achieved using simple means.

A three-rows-of-ball bearings sliding rail is disclosed. An inner sliding rail body is supported in outer sliding rail bodies through three rows of support ball bearings which are arranged in parallel in a lengthwise direction of the inner sliding rail body. The three rows of support ball bearings are respectively limited within a length range of the outer sliding rail bodies via ball retainers. Each of the outer sliding rail bodies includes a bottom plate, a first side wall and a second side wall which are respectively located at two sides in a widthwise direction of the bottom plate, are integrally formed with the bottom plate and extended in a lengthwise direction of the bottom plate. The first side wall includes a first arm and a supporting part which is bent inwardly and extends horizontally from a bottom end of the first arm.

A device for coordinated control and operation of double doors having a plate with a rectilinear motion that is associated with links with adjustable lengths that connect the plate to the double doors, with both the first and the second doors opened when one of the doors is opened and sequentially closed when one of the doors is closed.

A device for fixing a push element, in particular a drawer box to a rail of a pull-out guide, the device comprising a clamping mechanism with a receptacle, into which a web-shaped holding part can be inserted, wherein a self-locking clamping element is provided at the receptacle, by means of which the holding part is secured in a clamping manner against being pulled out. As a result, a particularly stable fixation of the drawer box to a pull-out guide can be achieved.
