Page 1890 | 3.8 Adjusting, Moving with Guides, Spindles and Ball Rollers GN 1440 Telescopic Slides continued Type B with rubber stop The rubber stops dampen the impact of the slide in the two end positions. This feature minimizes noise develop- ment and increases the service life. Attached to the slides in a partially concealed, partially visible manner, the stops meet each of the requirements in regards to shape, mate- rial, and hardness. If larger static or dynamic loads occur in the direction of extension, they should be absorbed by additional end stops. Type M with rubber stop, latch in retracted position Type M is used in applications where the slide is to be latched in the retracted end position. This feature prevents the slide from extending on its own, for example due to an inclined position. If larger loads occur in the direction of extension in the latched position, they should be absor- bed by additional latch elements. When closed, the latch mechanism locks into place un- der spring load via a recess on the outer rail. Pressing the release lever releases the inner and middle slide for extension. Back in the retracted position, the mechanism automatically locks into place again via the recess on the outer slides by moving over a ramp. Type K with rubber stop, latch in extended position Type K is used when the extension is to remain in the extended position for a certain amount of time. This fea- ture allows maintenance work to be performed with the slide being extended, for example. If larger loads occur in the latched position, they should be absorbed by additio- nal latch elements. For the function to be activated, the slide has to be fully extended to the front, where it will automatically lock into place via a pretensioned latching lever. Pressing the lever releases the slide, allowing the slide to retract again. Type Q with rubber stop, latch in extended and retracted position Type Q unites the properties of types M and K. The inner and middle slide lock into place in the two end positions. Unlike the release of type K, type Q is actuated through an internal rod by a convenient “remote control.” To do this, the green release lever is pressed outwards, the latching lever is activated, and the slide is released for retraction.
