摘要： A lockout device is mounted on a bike fork to selectively enable or disable the function of a shock absorber installed in the fork. The lockout device includes an activating mechanism, a shifting mechanism and a lockout mechanism. The activating mechanism can activate a rotational motion and is fitted around the shifting mechanism. The lockout mechanism includes a non-deforming unit and a deformable unit, one of which is mounted on the activating mechanism while the other unit is associated with the shifting mechanism. When a handle of the activating mechanism is rotated, the deformable unit is either pressed by the non-deforming unit and enters a locked state, or separated from the non-deforming unit and enters a released state, and accordingly, sets the shifting mechanism to an unmovable state or a movable state, respectively, relative to the activating mechanism, which in turn disables or enables the shock absorber, respectively.

摘要： An apartment staircase automatic lift, comprising a combined structure of a carrying guiding-rail, a transmission-set main-body and a driving module; wherein the transmission-set main-body is set with a carrying wheel-seat and a transmission-set carrying-shelf; wherein the transmission-set carrying-shelf is set with a foot-pedal; when a person stands on the foot-pedal, the driving module can be controlled to drive the transmission-set main-body and the foot-pedal to move back and forth along the carrying guiding-rail between the upper and lower ends of the carrying guiding-rail; thereby helping the person to go up and down the staircase. The overall structure has the advantages of low cost, easy installation and operation, and compact structure; which can improve the defects of the conventional staircase-lift seat including the large volume size, occupying large staircase space, and being inconvenient to be arranged in a general apartment staircase.
