The dampened self-retracting mechanism is divided into two main functions and offers the best possible ease of use on closing the extension. The self-retracting mechanism takes over the automatic retraction of the slides on the last 47 mm of stroke in the back stop position, where the slides are held in place ac- cordingly. The retraction force is about 40 newtons per slide pair. Also, the dampening mechanism slows down to a considerably reduced speed the closing movement on the said stroke. An extremely smooth and gentle clo- sing movement is achieved. This retraction force has to be overcome accordingly on opening the extension. The dampened self-retracting mechanism is designed for loads weighing up to 36 kg based on 60,000 cycles (LGA standard). Proper use, including the reduction of the stro- ke speed to no more than 0.15 m/s on reaching the ret- raction mechanism, as well as compliance with the load values are required. In this slide variant the available retraction force can be regarded as a locking device, which is noticeable through a slight restriction on opening the extension. Detach function Type F has additionally a detach function through which the extension slides can be completely separated from one another in the area of the middle and inner slide. This feature not only facilitates mounting. It also allows the extension to be quickly removed, for example, when fre- quent maintenance work is performed on the components located behind. The telescopic slide can be quickly and easily detached in the extracted position through activation of the release lever, allowing the inner slide to be removed from the front. For reattaching the slides, the ball cages need to be moved to the front end position. Then the inner slide is inserted to the back end stop where it locks into place automatically. The protected arrangement of the release mechanism pre- vents accidental detachment of the slide.
