Abstract: A lever-operated latch device includes an assembly of a case body, an actuation body mounted on the case body, a linking member and a slide body. The actuation body has a free end and a pivoted end pivotally connected with the case body in cooperation with elastic members. The free end of the actuation body is formed with two protruding arms and an opening section positioned between the protruding arms. An operation section is disposed in the opening section. The linking member has a first end pivotally connected with the free end of the actuation body (or the operation section) and a second end connected with the slide body. When an operator presses the operation section, the actuation body is permitted to move from a closed position to an opened position so as to drive the linking member and the slide body to move.

Abstract: A hinge includes two rotatable axle units disposed on a base seat and each having two rotatable hinge shafts, two movable bracket units each including a base plate, two rotary blocks non-rotatably sleeved on the hinge shafts, and two movable plates movable relative to the rotary blocks, and two synchronizing units for making synchronous rotations of the hinge shafts. Each synchronizing unit includes a first gear member having two end surfaces in form of bevel gears, and two second gear members each meshing with the respective end surface and fitted to the respective rotary block. Rotations of the hinge shafts at one side of the base seat result in rotations of the rotary blocks and the second gear members, and bring in rotations of the second gear members, the rotary blocks and the hinge shafts at the other side to make the synchronous rotations.

Abstract: A monitor support device includes a base support and first and second supports mounted to the base support. The first support includes a first connecting body rotatable about a first rotational axis, and a first mounting body adapted to be mounted with a first monitor and rotatable relative to said first connecting body about a second rotational axis. The second support includes a second connecting body rotatable about the first rotational axis, and a second mounting body adapted to be mounted with a second monitor and rotatable relative to said second connecting body about a third rotational axis. The second and third rotational axes each defines an 45° angle with the first rotational axis.

Abstract: A flexible electronic device includes a flexible display, a support mechanism for carrying the flexible display thereon, and two hinge mechanisms. Each of the hinge mechanisms is disposed between first and second substrate units and interconnects inboard end edges of the first and second substrate units of the support mechanism, and includes first and second linking units pivotable relative to a mounting assembly. With a first height between first outer and inner pivot axes of the first linking unit and a second height between second outer and inner pivot axes of the second linking unit, substrate seats can be moved away from inner support plates, and the inner support plates are movable downwardly to provide a leeway space for a bending part of the flexible display to be bendably received therein.

Abstract: A hinge mechanism connectable with two housing shells for a flexible display to be attached thereto includes a base seat, a torque transmitting unit and two rotary members. The base seat defines therein a rail region and two mounting regions. Each mounting region is defined by an arcuate bottom wall and first and second ribs. The torque transmitting unit includes two transmitting shafts and a synchronously driving member. The rotary members are disposed at the mounting regions to be pivoted about the transmitting shafts so as to bring the housing shells into unfolded and folded states.

Abstract: A torsion washer integrally formed as a one-piece structure includes an external ring-shaped portion, a first abutting arm and a second abutting arm both separately extending from an inner edge of the external ring-shaped portion, and a connecting lever connecting the first and second abutting arms. The inner edge includes a first arc segment and an opposite second arc segment, and centers of circle of the first and second arc segments are located in a space surrounded by the inner edge. Free ends of the first and second abutting arms do not contact the inner edge. A distance between a first abutting portion of the first abutting arm and the first center of circle is less than a radius of the first arc segment. The connecting lever is spaced apart from the inner edge, allowing the first and second abutting arms to be interlinked with each other.

Abstract: A three-section slide rail device includes an outer section, a middle section and an inner section. The middle section includes a middle rail and an inner middle block. The inner section includes an inner rail slidably disposed on the middle rail, and a removal operating assembly disposed on the inner rail. The removal operating assembly has a removal operating member, a removal connecting plate and a removal locking member pivotably mounted on the inner rail and having a removal guiding slot. The removal locking member has a locking portion and a protrusion. The removal operating member is operated to move the removal connecting plate and bring the protrusion to move along the removal guiding slot to result in pivoting of the removal locking member so as to disengage the locking portion from the inner middle block for permitting removal of the inner section from the middle section.

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 is connectable with two housing shells for permitting relative folding and unfolding of the housing shells, and includes a fixed seat, at least two rotating units, two lateral support plates and at least one synchronous driving unit. The rotating units are shiftable between an open state and a closed state. Each rotating unit includes a linking member fittingly and arcuately slidable on the fixed seat, a sliding member fittingly and arcuately slidable on the linking member, and a rotary bracket pivotably mounted on the fixed seat and inclinedly slidable on the sliding member. The lateral support plates are respectively mounted on the linking members. The synchronous driving unit includes two inboard pinions and two outboard pinions arranged laterally to mesh with bracket toothed portions of the rotary brackets to make synchronous rotation of the rotary brackets in opposite rotational directions.
