The present invention relates to a refrigerator. A refrigerator according to an aspect includes a cabinet in which a storage compartment is formed; a first refrigerator door which is capable of opening and closing the storage compartment; second refrigerator door which is disposed along with the first refrigerator door in a lateral direction; and a door opening device which is capable of operating in order to open and close at least one of the first refrigerator door and the second refrigerator door, wherein the door opening device includes a motor for generating a driving force; a push rod which operates by receiving the driving force generating from the motor; a gear for transferring the driving force of the motor to the push rod.

A refrigerator appliance includes a cabinet defining a food storage chamber. A door is positioned on the cabinet and is movable between a closed position and an open position. A door opener includes a casing, a gear box, a sliding nut movable relative to the gear box, and a finger extending through the gear box. The finger is movable with the sliding nut. The door opener also includes a sensor. The finger extends outside of the casing to contact an inner surface of the door when the door is in the closed position and the door opener is in a zero position. The sensor is configured to detect movement of the door opener from the zero position.

The triaxial hinge includes a first hinge shaft attached to a first casing via a first bracket, a second hinge shaft attached to a second casing via a second bracket and a third hinge shaft coupled to one end portion of a first coupling part and one end portion of a second coupling part. Respective other end portions of both coupling parts are attached to the first hinge shaft. There is a gear type synchronous rotation unit for transmitting a rotation of one of the first hinge shaft and the second hinge shaft accompanied by an opening and closing operation of the both casings to the other hinge shaft via the third hinge shaft, which is made to move in a forward and backward direction as accompanied by an opening and closing operation of the both casings.

The invention relates to a hinge (10) comprising a swivellable hinge part (12), a stationary hinge part (14) and a tensionable spring element (34), wherein the stationary hinge part (14) is designed with a first bearing (16) as well as a second bearing (18), wherein the bearings (16, 18) have swivel axes (S1, S2) that are offset to one another. According to the invention, the swivellable hinge part (12) is mounted on the stationary hinge part (14) via the first bearing (16) such that it can swivel about a swivel axis (S1), and the tensionable spring element (34) is arranged on the stationary hinge part (14) via the second bearing (18).

A power actuation system for a motor vehicle closure panel includes a motor operable to pivot a driven gear. At least one pawl assembly is operably supported by the driven gear for movement between a lever driving position, whereat the pawl assembly is positioned to pivot a lever coupled to the door to pivot the door concurrently with movement of the driven gear, and a lever releasing position, whereat the pawl assembly is positioned to permit free pivotal movement of the lever and door relative to the driven gear. The pawl assembly includes a roller engaged with the lever for rolling movement therealong during movement of the pawl assembly between the lever driving position and the lever releasing position, which results in minimal static and kinetic friction, thereby lending to reliable, low effort movement of the pawl assembly between the lever driving position and the lever releasing position.

In accordance with one aspect of the present disclosure, a movable barrier operator including a body, a motor supported by the body, and a rotatable drive supported by the body and configured to be connected to an elongated driven member. The movable barrier operator further includes a shaft supported by the body and a compound gear mounted on the shaft. The compound gear includes a first gear operably coupled to a drive shaft of the motor and a second gear operably coupled to the rotatable drive. The first and second gears connected such that turning of the first gear causes turning of the second gear.

A poly axial hinge comprising a mounting plate, a first arm pivotally coupled to a panel mounting element, a second arm pivotally coupled in an scissoring manner with the first arm by a main pivot, and a third arm pivotally coupled to the second arm at a location part way between a first end of said second arm and the main pivot. The mounting plate includes at least one rigidly fixed first gear, and the third arm includes gear teeth directly or indirectly coupled together with the fixed gear, such that rotation of the second arm with respect to said mounting plate causes rotation of the first arm with respect to the second arm, thereby driving the poly axle hinge open and/or closed.

A device for moving a leaf door, including an electric motor (30), a reduction gear box (40) and a crown wheel-pinion transmission system (50) is provided. The electric motor (30) is kinematically connected to the reduction gear box (40), which in turn is kinematically connected to the crown wheel-pinion transmission system (50). The reduction gear box (40) is reversible.
