Abstract: The present invention discloses a modular pivotal hinge comprising a pivotal shaft, a rotating bracket, a base, elastic means, and a buffering means. The pivotal shaft comprises an axle. The rotating bracket comprises a mounting part for fixation to a second member, and a rotating part for coupling to the axle and allowing said rotating bracket to pivot around said axle. The base comprises a mounting part for fixation to the first member and a slot constructed in a way to allow the axle to be inserted and secured therein. The elastic means provides a spring force to urge the second member to pivot away from the first member. The buffering means comprises a head for contacting the axle and a buffer structure elastically biasing against the head toward the axle.

Abstract: A pivotal hinge of which the axial elastic force may be adjusted through elastic pads is disclosed. The pivotal hinge comprises a pivotal member, a positioning bracket, a pivotal bracket and at least one elastic pad. Due to the adjustable axial elastic force, the frictional pivot contact between the positioning and pivotal brackets may be varied.
