The running carriage includes at least three rolling bodies, and each of the at least three rolling bodies has a cylindrical from and is rotatable about a horizontally extending axis in a mounted position of the drawer pull-out guide. The at least three rolling bodies of the running carriage, in the mounted position of the drawer pull-out guide, are arranged in at least three running planes lying above one another.

A drawer pull-out guide includes a first guide rail, a second guide rail displaceably supported relative to one another, and a running carriage having load-transmitting rolling bodies displaceably arranged between the first guide rail and the second guide rail. The running carriage includes at least two rolling bodies rotatable about a rotational axis, and the at least two rolling bodiesin a view onto a plane perpendicular to a longitudinal direction of the guide railsare arranged so as to be laterally offset to one another. Each of the at least two rolling bodies has a cylindrical form and is rotationally supported about a horizontally extending rotational axis in a mounted position of the drawer pull-out guide, the rotational axes of the at least two rolling bodies are arranged in the same running plane, and the at least two rolling bodies have the same diameter.

A steering shaft may include a hollow shaft in which an inner shaft is arranged telescopically coaxially in an axial direction. A rolling body may be held in a form fit manner in a circumferential direction and configured to roll in the axial direction in a rolling body holding element of a rolling body cage disposed between the inner and hollow shafts, which is arranged in the axial direction between radially projecting stop elements of the hollow shaft and of the inner shaft. The rolling body cage may have end-face axial support surfaces that are oriented in the axial direction against the stop elements. The rolling body cage may have at least one transfer element extending axially between the end-face axial support surfaces.

Provided is a sliding device that allows two release levers to operate in a synchronous manner. The sliding device includes a lock portion that is displaceable between a locking position and a non-locking position; a release lever configured to be displaced by an operating force; an operation portion provided at a first end of the release lever in an extending direction thereof to receive the operating force; an action portion provided at a second end of the release lever in the extending direction thereof to transmit the operating force to the lock portion via the release lever; and an operating lever provided to the movable rail and displaceable between an operating position to apply the operating force to the operation portion and a non-operating position to apply no operating force to the operation portion.

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 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 table leg includes a fixed outer tube, a movable inner tube vertically movable in the fixed outer tube and having two pairs of parallel walls, and a plurality of rotating members rotatably mounted to one pair of the parallel walls of the movable inner tube and partially protruding out from an outer surface of the movable inner tube and stopped against an inner surface of the fixed outer tube, such that the rotating members are rotatable when the movable inner tube is moved relative to the fixed outer tube.

In order to provide a guide device which is easy to build and enables efficient influencing of movement, it is proposed that the guide device comprises the following: at least two guide rails (112), which are movable relative to one another by means of a rolling element arrangement (12); and a movement device (134) for influencing the movement of the at least two guide rails (112) relative to one another.

The present disclosure relates to an ultrasonic imaging apparatus that has a tolerance for easy assembly and reduces shaking and noise by reducing the tolerance after assembly. The ultrasonic imaging apparatus includes a main body, a probe connected to the main body to irradiate and receive ultrasonic waves and to transmit the ultrasonic signals to the main body, a control panel configured to control the main body or the probe, and a moving device configured to connect the control panel and the main body and to move the control panel with respect to the main body in the upward and downward directions, wherein the moving device includes a housing fixed to the main body, a moving member configured to be movable with respect to the housing in the upward and downward directions, and a regulating bearing installed in the housing and configured to assist the upward and downward movement of the moving member by coming into rolling contact with the moving member and to regulate a gap with the moving member.

A table leg includes a fixed outer tube, a movable inner tube vertically movable in the fixed outer tube and having two pairs of parallel walls, and a plurality of rotating members rotatably mounted to one pair of the parallel walls of the movable inner tube and partially protruding out from an outer surface of the movable inner tube and stopped against an inner surface of the fixed outer tube, such that the rotating members are rotatable when the movable inner tube is moved relative to the fixed outer tube.
