Patent ID: 8213600

Claim:
A sliding mechanism, comprising: a body section defining a sliding slot, the sliding slot including a first slot section and a second slot section, the first slot section parallel and offset with respect to the second slot section; a cover section slidably mounted to the body section; a rolling disk fixed to the cover section, a guiding pole protruding from a center of the rolling disk, the guiding pole slidably received in the sliding slot; a first friction board; a second friction board, the first friction board and the second friction board parallel secured on opposite edges of the sliding slot; and a coil spring, a center of the coil spring fixed to a center of the rolling disk, an end of the coil spring fixed to a periphery of the rolling disk; wherein the rolling disk rotates along the first friction board and the coil spring generates a resisting force against the sliding direction when the guiding pole slides along the first slot section to the second slot section; the rolling disk rotates along the second friction board and the coil spring generates a repelling force towards the sliding direction when the guiding pole slides along the second slot section away from the first slot section.
