ABSTRACT:
An opening and closing apparatus of the folding type includes a guiding part, a slider, a first link, and a second link. The guiding part has a guiding protrusion and a guiding bend for longitudinal movement of the slider therein and is fixed on a frame. One side of the first link is hinged to the lower side of the guiding part. The other side of the first link is hinged to the link-connecting portion of the second link. Centering about the link-connecting portion, one side of the second link is hinged with a movable frame and the other side thereof is connected with a rotating part of the slider. The slider has friction-reducing portions to prevent the slider from frictional wear with the guiding protrusion, the guiding bend, and the slider connecting portion. The slider has a locking protrusion for maintaining the apparatus in a closed state.
