To provide an opening and closing device for opening and closing body having a rotation torque controlling module and a torque peak adjusting module, solution was sought by an opened and closed body and the opening and closing body which comprises an attaching part, an opening and closing part rotatably attached to the attaching part via a hinge shaft, a rotation torque controlling module for controlling a rotation torque of the opening and closing part, a torque peak adjusting module for adjusting a torque peak of the opening and closing part at the time of its opening and closing movement.

The present invention relates to a hinge device for a rotating door, and more particularly, to a hinge device for a rotating door, which is mounted on the rotating door so that the door can be opened and closed while rotating in various ways. The hinge device for the rotating door of the present invention rotates by an external force and then rotated in a free stop manner at a certain section, and automatically rotates in a reverse direction at a section where the hinge device reversely rotates after free stop rotation.

A hinge device for a rotary door is mounted to a door that is rotating to open and close the door while being rotated in various manners. The hinge device can be rotated in a free stop type in a predetermined section after it is rotated by an external force, and is automatically reversely rotated in a section in which it is reversely rotated after the free stop rotation.

The invention comprises a door closer (1), a slide rail (3) and an arm (2). The arm is connected to the door closer (1) and to the slide rail (3). The slide rail is provided with a hold open device (4) in order to keep a door open. The arm (2) comprises an outer arm (8A, 9A) and an inner arm (8B, 9B). The inner is situated partly inside the outer arm in a sliding manner. The arm (2) also comprises a spring arrangement (11) in order to hold the inner arm (8B, 9B) in a normal position in the outer arm (8A, 9A), and a release device (10A, 10B). The release device is arranged to release the inner arm (8B, 9B) from its normal position when an external force being strong enough to active a release of the release device (10A, 10B) drives the inner arm (8B, 9B) out from the outer arm (8A, 9A).

The present invention relates to a hinge device for a rotating door, and more particularly, to a hinge device for a rotating door, which is mounted on the rotating door so that the door can be opened and closed while rotating in various ways. The hinge device for the rotating door of the present invention rotates by an external force and then rotated in a free stop manner at a certain section, and automatically rotates in a reverse direction at a section where the hinge device reversely rotates after free stop rotation.

An angularly variable device for use on a door having a closer piston with a piston arm wherein the angularly variable device is a protracting blocker comprised of a first section and a second section. Each section comprises a wall from which extends at least one tab extending perpendicularly therefrom. From the wall extends generally perpendicularly at least one but preferably a plurality of tabs so that the at least one tab on each of the first section and the second section rests on top of the piston arm. A retainer presses against an elbow joint forming part of the piston arm so as to firmly press the wall against the piston arm so that one side of the blocker is pressed against one side of the piston arm while the retainer presses against the opposite side of the piston arm so as to provide a secure installation of the blocker on the piston arm. A lever pivoted into a horizontal position presses the two sections together so that they remain in a given fixed position relative to each other so as to immobilize the piston arm in a given position.

A resin back door for a vehicle includes a resin inner panel, a resin lower outer panel, a metal left reinforcing member, and a damper stay bracket. The metal left reinforcing member is disposed in a hollow space defined by the inner panel and the lower outer panel, and is fixed to the inner panel with an adhesive leaving a gap. The damper stay bracket is attached on an outer side of the inner panel in a vehicle width direction. In the resin back door for a vehicle, the damper stay bracket is fastened to the left reinforcing member across a collar having one end inserted into a hole provided in the inner panel.

An automatic door stopping-closing device comprises a cylinder with a connecting rod, one end of which is connected to a door; a bracket assembly on the door frame, comprising a hook connected with the other end of the rod, a movable lug cooperated with the hook, and a pull rod cooperated with the movable lug, wherein the pull rod and the hook can be engaged or disengaged. After the door is opened, the door can be kept open securely through the cooperation between the hook and the movable lug; and the door can be closed automatically by a slight push, through the cooperation between two of the hook, the movable lug and the pull rod. The automatic door stopping-closing device holds the door open without external force after the door is opened, and closes the door automatically after a slight push.

A friction based counterbalance mechanism for coupling with a closure panel of a vehicle, the counterbalance mechanism including: a housing having a first pivot mount for connecting to one of a body of the vehicle and the closure panel; an extension member coupled to the housing and being extendable and retractable with respect to the housing, the extension member for connecting by a second pivot mount to the other of the body and the closure panel; a variable friction mechanism mounted in the housing having: a shaft having an axis; a washer positioned on the axis; a pinion with a friction body positioned on the shaft and adjacent to the washer, the pinion rotatable about the axis relative to the washer during rotation of the shaft to generate friction between the washer and the friction body; and a slider body positioned on the axis.

A guide system includes a first guide rail for guiding a door wing, a second guide rail for guiding the door wing. A carrier can move the door wing relative to the second guide rail in a direction extending transversely to the longitudinal direction of the first guide rail. A drive device has a force storage member, and the carrier can be at least partially ejected by the drive device from the retracted position of the carrier by a force of the force storage member. The drive device includes a coupling portion and a control curve, and the coupling portion and the control curve are decoupled over a large part of the movement of the carrier between the extended position and the retracted position. The carrier can be retracted into the retracted position starting from a position immediately before the retracted position when the coupling portion couples with the control curve.
