Disclosed herein is a hinge unit of a console armrest for a vehicle, which includes an upper bracket including an armrest installation part coupled to an armrest, and upper hinge parts formed at both sides of the armrest installation part, each having a first upper hinge hole, a lower bracket including a console installation part coupled to a console, and lower hinge parts formed at both sides of the console installation part, each having a first lower hinge hole, an upper bracket cover configured to surround at least a portion of each of the upper hinge parts and to have a second upper hinge hole formed at a position corresponding to the first upper hinge hole, and a lower bracket cover configured to surround at least a portion of each of the lower hinge parts and to have a second lower hinge hole.

An automotive door hinge comprises first and second brackets mountable selectively to one of the door and the body. A cam element, non-rotationally mounted to the second bracket, comprises a cam surface adapted to engage with a cam follower non-rotationally housed within a first housing of the first bracket. An energy storage means respectively stores and releases energy when the cam follower longitudinally translates within the first housing in a first direction and then in a second direction opposite the first direction. Relative rotation of the first bracket in relation to the second bracket within a predetermined angular range causes longitudinal translation of the cam follower, wherein as the door is closed, the cam follower engages the cam surface and translates longitudinally in the second direction whereby the energy stored by the energy storage means is released to assist door closure.

A closing hinge device includes a fixed element, a movable element and a pair of counteracting elastic members. One of the movable element or fixed element includes a generally box-shaped hinge body with a pair of working chambers to slidably house the counteracting elastic members. The other of the movable element or fixed element includes a pivot having a cylindrical portion that includes a pair of substantially equal grooves angularly spaced at 180 and each having a helical portion, the grooves communicating with each other to define a single guide element passing through the cylindrical portion. The box-shaped hinge body includes elongated slots, a pin being inserted through the single guide element and through the elongated slots to slide therethrough, and the counteracting elastic members act on the pin to promote the automatic returning of the closing element from the open position to the closed position.

A hinge device includes a fixed element, a movable element and a slider housed in a working chamber and coupled to a pivot, so that a rotation of the movable element corresponds to the sliding of the slider. The working chamber includes an end cap and a working fluid and is divided into first and second variable volume compartment by a plunger member of the slider. A hydraulic circuit includes a first duct passing through an end cap that is in fluid communication with the first and second compartments and has an elongated tubular wall extending within the working chamber, and the interspace between the working chamber and the elongated tubular wall. The plunger member is tightly inserted in the elongated tubular wall, which includes a first peripheral conduit having a first and a second port in fluid communication with the first and respectively second compartment through the first duct.

A refrigerator includes a cabinet, a storage compartment within the cabinet, a main door to open or close the storage compartment, an auxiliary storage compartment mounted to a rear surface of the main door and configured to be accessed through an opening in the main door, a sub door to open or close the opening leading to the auxiliary storage compartment, a hook member at the sub door, a latch cam pivotally mounted in the main door to be selectively caught by the hook member, a stopper pivotally mounted at a location above the latch cam to selectively limit pivotal rotation of the latch cam, a solenoid device mounted below the latch cam to laterally push the stopper via a vertical movement caused by the solenoid device to release locking between the stopper and the latch cam, and a controller provided at the sub door to selectively operate the solenoid device.

A hinge device includes a first fixed tubular half-shell having a working chamber defining a longitudinal axis, a second tubular half-shell rotatable about the longitudinal axis, a pivot rotating unitary with the latter which includes a single pass-through actuating member having a helical shape, a plunger member slidable along the longitudinal axis, and a tubular bushing having a pair of guide cam slots. A pin inserted within the pass-through actuating member is provided to allow the mutual engagement of the pivot and the bushing. The first tubular half-shell includes an end portion susceptible to rotatably support the pivot, the second tubular half-shell and the bushing are coaxially coupled to each other, and the bushing and the first tubular half-shell are mutually unitarily coupled.

A hinges structure (10) includes a first hinge (12) and a second hinge (14), each of them being fixed at a part to a fixed system F and at the other part to a wing B. The hinges structure (10) includes a cam mechanism for an automatic closing of the wing B and a fluid-operated device adapted to move a fluid from a first chamber to a second chamber through the rotational motion of the wing B. The speed of displacement of the fluid may be conveniently adjusted through a valve and consequently, the closing speed of the wing may be controlled.

A hinge device includes a first fixed tubular half-shell having a working chamber defining a longitudinal axis, a second tubular half-shell rotatable about the longitudinal axis, a pivot rotating unitarily with the latter which includes a single pass-through actuating member having a helical shape, a plunger member slidable along the longitudinal axis, and a tubular bushing having a pair of guide cam slots. A pin inserted within the pass-through actuating member is provided to allow the mutual engagement of the pivot and the bushing. The first tubular half-shell includes an end portion susceptible to rotatably support the pivot, the second tubular half-shell and the bushing are coaxially coupled to each other, and the bushing and the first tubular half-shell are mutually unitarily coupled.

A counterbalance hinge assembly includes a cam and compression device that counterbalances a weight of a door or a ramp. The compression device biases against a rotation of the door or ramp. The downward movement of the door or ramp drives cam followers in angled slots or cam surfaces of the cam. The angled slots or cam surfaces include varying angles of incline to correspond to varying torque forces of the door or ramp during the opening or closing movement of the door or ramp.

A fixation seat having a first guiding element and a second guiding element mounted inside of a hinge mechanism is mounted at a wall or a frame's surface. A first guided assembly and a second guided assembly are mounted at the fixation seat and respectively guided by the first guiding element and the second guiding element to move away from each other or move back. A movable assembly comprises a movable and pivotable shaft mounted through the fixation seat and optionally connected to the first guided assembly or the second guided assembly. A door is mounted at the movable assembly and pivots relative to the surface through the shaft. The movable assembly lifts and lowers the door via the shaft, connected one of the guided assemblies, guided by the guiding elements, so the hinge mechanism is adaptable to install the door at left-side or right-side surfaces.
