A retention assembly may comprise a motor assembly and a self-locking worm drive coupled thereto. A cam may be fixed to a worm gear of the worm drive. The retention assembly may further comprise an actuation shaft including a follower. The actuation shaft may be displaceable over a displacement range via rotation of the cam. The retention assembly may further comprise a securement member with a securement member follower, the securement member coupled to a portion of the actuator shaft. The retention assembly may further comprise a housing cam included as part of the retention assembly housing and against which the securement member follower may be biased. The securement member may be in an open state when the actuation shaft is in a first position. The securement member may swing outward to a retaining position as the actuation shaft is moved to a second position.

To provide the original cover closer which can control a rotation torque accompanied with an opening and closing operation of in a simple structure, as compared to the conventional original cover closer, solution is made in that the original cover closer comprises an attaching part attached to the main body side; a supporting part, wherein its side plates are rotatably attached to the both side plates of the attaching plate via a hinge shaft, as well as the original cover is attached to the supporting part; a pressure receiving part provided between the both side plates of the attaching part; a cam slider slidably provided inside the supporting part by making its cam portion abut against the pressure receiving part; an elastic module resiliently provided between the cam slider and a free end side of said supporting part, so as to bring the cam slider into press contact with the pressure receiving part and to rotatably urge the supporting part in an opening direction of an original cover; and a brake module provided between the supporting part and the cam slider, and that the brake module consists of a plurality of friction protruding ridge portions provided on an inner wall surface of the supporting part toward the cam slider, and at least a gently-sloping upward inclined portion gradually climbing from the cam slider side is provided on each of the friction protruding ridge portions.

A shower door and hinge assembly comprising a glass shower door, a sloping sill, a sill angle adapter, upper and lower horizontal door frame rails, and upper and lower shower door hinges where the lower hinge is a gravity style hinge featuring a self-closing action, is presented. The hinges of the present invention shower door and hinge assembly attach only to horizontal edge surfaces of the glass door. The hinges do not attach to any vertical surface of the door.

An appliance lid hinge assembly includes a cam arm pivotally connected a base. A cam arm control system includes a spring rod adapted to move in a sliding reciprocal manner. A spring urges the spring rod toward an extended position. The spring rod is movable toward a retracted position. The cam arm is engaged with the spring rod through a cam follower such that: (i) pivoting movement of the cam arm in an opening direction corresponds with movement of the spring rod from the retracted position toward the extended position; and, (ii) pivoting movement of the cam arm in a closing direction opposite the opening direction corresponds with movement of the spring rod from the extended position toward the retracted position. An optional damper exerts a damping force on the spring rod or other part of the cam arm control system when the cam arm moves in a closing direction.

In one example, a hinge assembly is disclosed, which may include a band torque engine having at least one bearing portion and a vertical torque engine coupled to the band torque engine. The vertical torque engine may have an opening. The hinge assembly may include a first shaft received through the at least one bearing portion and the opening. The first shaft may be rotatable along an axis with respect to the band torque engine and the vertical torque engine. The hinge assembly may include a display bracket including an adaptor portion to hold the first shaft such that the first shaft rotates along with the display bracket. The band torque engine may provide a frictional torque and the vertical torque engine may compressively engage with the first shaft to provide a vertical frictional torque during rotation of the display bracket.

A hinge for assembling a door on a piece of furniture comprises a first hinge element fastenable to a fixed part of the piece of furniture, a second hinge element fixable to a door of the piece of furniture and swingably connected to the first hinge element, and at least one spring element for generating a force in the opening direction for the door at least near the closing position of the door; the at least one spring opening element is housed in an opening device disposed in or on one of the first and second hinge elements, wherein the opening device is conformed and arranged for exerting said opening force directly or indirectly on the other of said first and second hinge elements.

A snap-acting hinge with damped closure and opening angle of more than 90, comprising a first articulated quadrilateral and a second articulated quadrilateral, which have a first lever and a second lever in common and are provided with respective base elements constituted by a plate for coupling to a fixed element and by a plate for fixing to a movable element, the hinge being movable between an open configuration and a closed configuration; the hinge further comprises first elastic elements for holding the open configuration which are associated with the first quadrilateral, second elastic elements for holding the closed configuration which are associated with the second quadrilateral and a damper that acts in the transition from the open configuration to the closed configuration and which is interposed between the first lever and the fixing plate.

An actuating arm drive for a pivotably mounted actuating arm includes a pivotably mounted main lever, a force accumulator for exerting a force for supporting the opening and/or closing movement of the actuating arm drive on the main lever at a force introduction point, and a setting device for setting the force introduction point on the main lever. The force is introduced to the main lever at the force introduction point via a force introduction element which is loaded by the force accumulator via levers, and the setting device is designed to move the force introduction element along a bearing contour formed on the main lever. In each pivoting position of the main lever between the open and closed position of the actuating arm drive, and in each setting of the setting device, the loaded force introduction element is forced along the bearing contour in the same direction.

A hinge for the rotatable movement of a closing element, such as a door, a window, a shutter or the like, includes a fixed element anchorable to a stationary support structure and a mobile element anchorable to the closing element. The fixed and movable elements are mutually coupled so as to rotate with respect to each other between an open position and a closed position. One of the fixed or movable element includes a working chamber, with a plunger disposed to slide along a longitudinal axis and operatively coupled with the other one of the fixed or movable elements so that the sliding of the plunger corresponds to a rotation of the movable element.
