US Patent 7426115 Dynamic sliding module and uses thereof

A dynamic sliding module is described. The dynamic sliding module includes a track, a dynamic slide, and a guiding device. The track includes a first opening and the guiding device is disposed adjacent to the first opening. When the dynamic slide slides along the track and aligns with the first opening, the guiding device provides a guiding force to guide the dynamic slide to move toward the first opening and enter into the track for sliding thereon. The track further includes a second opening to allow the dynamic slide to be withdrawn form the track. The dynamic sliding module further includes an elastic device and/or a wedge-shaped device disposed adjacent to the second opening to assist the dynamic slide to be withdrawn from the track.
