Abstract: A multi-link hinge assembly includes a link rod unit including a base rod, two supporting link rods, two synchronization link rods, two supporting rods, and a supporting plate unit. The base rod has a base rod body, two base connecting portions respectively connected to opposite ends of the base rod body, and two central connecting portions disposed between the base connecting portions. Each synchronization link rod has a first synchronization end portion pivotably connected to a respective one of the central connecting portions, and a second synchronization end portion opposite thereto. The supporting plate unit includes two supporting plates respectively connected to the supporting rods and each having inner and outer portions. The link rod unit is operable between an unfolded position and a folded position, where the second synchronization end portions are away from each other, and the inner portions define a relief space therebetween.

Abstract: A hinge includes a base frame, a support frame and a transmitting mechanism. The base frame includes front and rear ends. The transmitting mechanism includes a first sliding plate, a second sliding plate and a transmitting assembly. The first and second sliding plates are connected with and slidable relative to the base frame in a front-rear direction. The transmitting assembly includes a rotating axle unit and a linkage unit. The rotating axle unit is movable with the support frame to cause sliding movements of the first and second sliding plates and a pivoting of the linkage unit relative to the base frame so as to shift the first and second sliding plates between retracted and projecting states.

Abstract: A hinge includes a base frame unit and two rotatable axle units. The base frame unit includes a base seat and a protective cover. The base seat has two guideways having upper and lower segments, and two shaft sliding slots. The protective cover has a base wall and two pivot pins. Each axle unit rotatably extends through the base seat, and includes a hinge shaft rotatably extending through the shaft sliding slot, a first rotary member non-rotatably fitted to the hinge shaft, a second rotary member connected with the first rotary member, and a support bracket non-rotatably fitted to the hinge shaft. The first rotary member has a guide key slidably engaged in the guideway. The second rotary member is pivoted to the pivot pin and has an engaging hole for receiving the guide key.

Abstract: A multi-position hinge includes a base seat, a first axle, a second axle and a sliding assembly. The first and second axles rotatably extend through the base seat in a first direction and are spaced apart from each other in a second direction. The first axle has a first recess, a second recess and a first gear portion. The second axle has a third recess, a fourth recess and a second gear portion corresponding with the first recess, the second recess and the first gear portion, respectively. The sliding assembly includes a first sliding member engageable with the first and third recesses, and a second sliding member engageable with the second and fourth recesses. The first and second axles are rotatable in turn and then rotated synchronously to perform multi-position shifting.
