摘要:
A hinge assembly that includes a closure member such as a door and a torsion bar that extends between hinge assemblies about which the door pivots so that the torsion bar becomes twisted when the door is moved between a closed position and an open position. The twisting of the torsion bar creates potential energy in the torsion which can be used to open or close the door. A force adjustment mechanism is provided which releases built-up potential energy in the torsion bar in a controlled manner so as to close open the door in a controlled manner.

A catcher (2) provided in a door frame H′ for capturing a striker body 1 moved from a near front side F when a door D′ is rotated toward a reference position; a braking device (5); and a linkage device (3) for both are provided. The catcher (2) is provided to be reciprocatingly rotatable between a standby position and a rotated position, captures the striker body (1) at the standby position, and rotates forward to the rotated position. Braking of the braking device (5) is applied to a rotation toward the rotated position of the catcher (2) through the linkage gear member (30).

A swinging door hinge has a panel and a frame. The frame includes a horizontal portion, and the horizontal portion has an aperture therethrough. An elongated pivot pin is vertically disposed through the aperture. The pivot pin is coupled to the panel such that the pivot pin and the panel rotate about a longitudinal axis of the pivot pin relative to the horizontal portion of the frame. A gripper feature is located on a surface of the pivot pin. The gripper feature engages a corresponding surface on the panel such that when the panel is rotated, a resulting torsional force transferred to the pivot pin is spread over a contact area between the gripper feature and the surface of the panel. Because the torque is transferred over a greater area, stress concentrations in the panel are reduced and the panel is not deformed.

A non-helical, multiple compound element, true torsion system includes a working element to be connected to a load, an adjustable control element and a drive for driving the control element. At least one S-shaped compound torsion element has ends each being connected to a respective one of the working and control elements.

A tailgate counterbalancing hinge assembly includes a linear torque rod, a first end assembly and a second end assembly secured to the torque rod. One end assembly pivotally supports the tailgate while permitting a torque rod end to be rigidly coupled to the tailgate for movement with the tailgate about a pivot axis. The other end assembly also pivotally supports the tailgate and permits the other end of the torque rod to be rigidly connected to the vehicle body. The assemblies are easily mounted in the vehicle by means of brackets secured to the tailgate, and a vehicle body hinge pin combines bushings with an aligned, elongated key to simplify installation and removal of the counterbalancing hinge assembly.

摘要:
A rotary friction damper in a device for connecting a door to an adjacent structure such that the door pivots about an axis during opening and closing of the same and including a torsion spring operatively connected to the door and to the structure for movement about the pivot axis to store energy during opening of the door and to release energy to provide closing during closing of the door. The rotary friction damper is operatively associated with the torsion spring and has an axis of rotation disposed substantially parallel to the pivot axis for controlling the door closing speed. A damper housing rotates in response to application of input rotational force, and damper shoes within the housing are moved radially outwardly into frictional engagement with the housing. An arrangement of disc springs applies biasing force in a direction parallel to the axis of rotation of the damper, and the biasing force is directed to cause radial outward movement of the shoes. The biasing force is varied as a function of the rotational position of the applied force by the combination of a cam having a surface profile shaped to vary the biasing force and a cam element contacting the surface and moved in response to application of the input rotational force.
