Abstract:
An adjustable snap-acting hinge is provided. The hinge includes a first articulated quadrilateral and a second articulated quadrilateral, which can move on a working plane and share a first lever and a second lever and are provided respectively with a plate for coupling to a first element and with a plate for fixing to a second element. A contrast element is associated with the coupling plate and can be arranged in at least one position for use, which lies between a first position in which the contrast element is arranged at a maximum distance from the point of the first lever, and a second position in which the contrast element is arranged at a minimum distance from the point of the first lever. The hinge also includes locking means for keeping the contrast element in the position for use.
Abstract:
The disclosed embodiments relate to an electronic circuit for a motor-driven door of a rail vehicle, said electronic circuit having a series circuit of a first non-linear element and a first controllable switch between the motor terminals. The first non-linear element is poled such that the resistance thereof to a current generated by the drive motor during a closing movement of the door is greater than during an opening movement. If a supply voltage for the door is present, the resistance of the first switch is effected relative to the resistance when said supply voltage is absent. The invention further relates to a door module for a rail vehicle having such an electronic circuit, to a rail vehicle for such a door module, and to a use of the electronic circuit.
Abstract:
A hinge for a door anchored to a wall, the hinge including a fixed element coupled to the wall and a movable element coupled to the door. The fixed and movable elements rotate between an open position and a closed position about a first longitudinal axis. One of the movable and fixed elements includes cam means rotating about the first longitudinal axis, the other of the movable and fixed elements including follower means mutually interacting with the cam means for sliding along a second longitudinal axis substantially perpendicular to the first axis. The follower means includes an elastic counteracting element. The cam means includes a first cam element interacting with the follower means for movement from end-stroke positions to an intermediate position and vice-versa. The cam means further includes a second cam element interacting with the follower means for movement from the intermediate position to the end-stroke positions and vice-versa.
Abstract:
A locking device for securing a motor vehicle component which is displaceable relative to a motor vehicle structure and which may be secured by means of the locking device within a displacement range in a respective position of rest reached by displacement is provided. The locking device comprising at least one first frictional element and at least one second frictional element, which is moved relative to the first frictional element upon displacement of the motor vehicle component and thereby may slide with a friction surface along a friction surface of the first frictional element under sliding friction conditions and which, in a respective position of rest of the motor vehicle component, with its friction surface bears against the friction surface of the second frictional element under static friction conditions. A flowable additional medium is provided which may be brought, upon a relative movement of the frictional elements, between their friction surfaces.
Abstract:
A hinge for a door, flap or similar pivotal wings of a motor vehicle is provided. The hinge includes a column-side hinge part and a door-side hinge part, which can be pivoted about a hinge pillar relative to each other, and with an integrated door retaining device, which includes a retaining element arranged on the side of the one hinge part, which cooperates with a retaining contour on the side of the other hinge part. The retaining element is formed as clamp element cooperating with a clamping surface of the hinge pillar, the clamping force of which can be adjusted by means of a transmission element as a function of the retaining contour.
Abstract:
The instant disclosure relates to a door damping apparatus for connecting to a door and an immobile frame. The door damping apparatus includes a shaft seat, a shaft, a cylinder, a piston, a spring unit, a check valve and a throttle valve. The interior of the shaft seat is formed with a fluid passage and a reservoir to store hydraulic fluid. The throttle valve projects into the fluid passage to adjust the flow of the hydraulic fluid, thus allowing the door to be opened smoothly and gently self closes.
Abstract:
A locking device for locking a displaceable motor vehicle part which is lockable by the means of the locking device within a displacement range in a respective rest position reached by displacement is provided. The locking device comprising a braking device with at least two braking elements which interacts in a braking manner in a respective rest position of the motor vehicle part in order to lock the motor vehicle part, and which can be brought into a position without braking engagement by inducing a release force into the braking device. An actuator is assigned to the locking device, which is optionally combinable with the braking device and with which a displacement movement of the motor vehicle part is brakable for locking the motor vehicle part.
Abstract:
A self-adjusting door closer is disclosed. The door closer is self powered and includes a control unit to intelligently control a valve within the door closer to vary the operating characteristics of the door closer as needed. The controller includes a position sensor to determine a position of the door, and at least one input switch to enable user selection of at least one door closer parameter for an installed door closer. The control circuitry is operable to set the valve in response to the user selection of the door closer parameters, and the position of the door, in order to control force exerted by the door closer on the door. A generator can be provided to provide electricity to power the controller and store power to operate the controller.

Abstract:
A replacement hinge pin to cure the problem of an open door that swings waywardly under the influence of gravity. The pin has a pair of oppositely-disposed and oppositely-directed bulges for frictional engagement with the roll-formed knuckles of a butt hinge. Rotational adjustment of the pin increases the friction in the hinge enough to prevent a door from swinging waywardly.
