Abstract:
The invention relates to a drive device (20) for entrance/exit devices for public transit vehicles, comprising a drive unit (22) disposed in and driving a column (24) that rotates about an axis of rotation Z-Z during opening and closing operations, said column opening and closing an entrance/exit device. The drive unit (22) is supported in the vehicle by way of a support component (40) and the support component (40) acts as a counterbearing for a torque of the drive unit (22). A coupling device (72) is disposed between the drive unit (22) and the support component (40), said coupling device facilitating a rotation of the drive unit (22) about the axis of rotation Z-Z when a limit of the torque acting on the drive unit is exceeded.
Abstract:
A door hinge (10) according to the invention comprises a first hinge element (12) which is fastenable to a door frame (24) and a second hinge element (14) which is fastenable to a door leaf (28) and has a first hinge blade (20) and a second hinge blade (22). A first pivot axis (32) is connected, when the door hinge (10) is in a first operating condition, to the first and second hinge elements (12, 14) in such a way that the second hinge blade (22) of the second hinge element (14) is pivotable, when the door hinge (10) is in said first operating condition, about said first pivot axis (32), relative to the first hinge element (12), in a first pivot direction (Px), for the purpose of unblocking a door aperture which is bounded by the door frame (24). The first pivot axis (32) is decoupled from the first or the second hinge element (12, 14) when the door hinge (10) is in a second operating condition. A second pivot axis (48) is connected to the first and second hinge elements (12, 14) in such a way that, when the door hinge (10) is in the second operating condition, said first and second hinge elements (12, 14) are pivotable about said second pivot axis (48), relative to one another, in a second pivot direction (P2) which is opposed to the first pivot direction (P1), for the purpose of unblocking the door aperture which is bounded by the door frame (24).
Abstract:
Disclosed herein is an opening and closing device for a notebook computer. The opening and closing device includes hinge means for selectively opening and closing a monitor, drive means for driving the hinge means, and power transmission means for transmitting the power of the drive means to the hinge means in parallel. In an embodiment, the power transmission means includes a first gear installed on the hinge means, and a second gear installed on the drive means.
Abstract:
An electromagnetic frictionally engaged clutch for arranging inside a drive train connecting a drive motor and a vehicle door or flap. The arrangement ensures that the vehicle door is securely held in each intermediate position, when the clutch is in an idle state, while maintaining the possibility of a manual emergency actuation of the vehicle door. The rotor includes at least one permanent magnet in addition to the electric coil, such that when a current does not pass through the coil, the armature disk is pressed against the friction lining of the rotor, with a force which is strong enough for the vehicle door or vehicle flap to securely remain in position occupied when the clutch is an idle state, and for the friction engagement between the armature disk and the friction lining to be overcome when the vehicle door or vehicle flap is subsequently manually actuated.
Abstract:
A drive arrangement for a motor vehicle door or hatch which can be moved by a motor with a planet gear and a brake device with a brake. The brake device has a brake drive which is separate from the drive which drives the drive shaft and the brake is able to be moved at least from one of two positions into the other of the two positions by the brake drive. The brake can be an arc-shaped clip pivotally supported by a pivot axle with an inner periphery which is matched to an outer periphery of an element of the planet gear. The brake can be combined with the brake drive as an eddy current brake or can be operated by a further gearing or use of a permanent magnet with which an electromagnet is able to interact.
Abstract:
If only an operating button 14 is pushed, an electrically opening and closing mechanism 1 disengages a first clutch K1 while engaging a second clutch K2 to operate an electrically driving means 2 to automatically open or close a second member (e.g., a liquid crystal display panel) 4 which is rotatable with respect to a first member (e.g., a body having a plurality of keys) 3. If the operating button 14 is pushed, the second member 4 automatically rotates to an optional angular position with respect to the first member 3, and if the operating button 14 is released (if the operating button 14 is returned to the original angular position by the spring force of a second spring 23), the first clutch K1 is engaged at the optional angular position to hold the attitude of the second member 4.
Abstract:
An automatic sliding door opening and closing system comprises a continuous, powered belted drive system and a clamp arrangement capable of fixably and releasably attaching the automotive sliding door to the belt drive system so as to be automatically driven along a predetermined path and capable of releasing the belt drive system under predetermined conditions. The powered belt drive system is located so as to be combined with one of the door's standard sliding door hinge systems. The clamp arrangement is a rotary device biased into a pinching engagement on the belt of the belt drive system via a cam and spring arrangement.
Abstract:
A power-operated system for actuating the rear doors or liftgates of motor vehicles is disclosed. The system includes a strut assembly having two struts, each strut mounted on one side of the door between the door and the vehicle's door frame. One end of each strut is connected to a powered rotating arm. To open the door, the rotating arms change the angular orientation of the struts such that they have a substantial mechanical advantage. In this position, the force provided by the struts overcomes the weight bias of the door, thus opening the door. To close the door, the rotating arms change the angular orientation of the struts such that the struts have a decreased mechanical advantage, reducing the force provided by the struts, and therefore causing the door to fall closed under its own weight bias. A control system for controlling the power-operated system is also disclosed.
Abstract:
The device (2), which is used to lock running gear (1) guided in a rail (5) and is or can be connected to the latter, has a body (21, 22) in which a locking pin (23) is displaceably mounted and, by means of a resilient element (24), is held resiliently in a first position, so that the locking pin (23) can be brought by the action of a force from the first position, in which it can engage in a locking element (36, 53) provided in the rail (5) or connected to the rail (5), into a second position, in which it is released from the engagement in the locking element (36, 53). The locking device (2), which is constructed simply and cost-effectively, therefore permits dividing elements (90), such as sliding doors, sliding counters or folding walls, which are guided by the running gear (1), to be closed off securely.
Abstract:
A remote controllable dead bolt type of locking apparatus is to be retrofittedly mounted in conjunction with a conventional garage door which is to function to securely lock the garage door preventing unauthorized entry through the garage door. The locking apparatus uses an elongated draw bar assembly that connects between the right side door jamb and the left side door jamb which defines the transverse sides of the opening within which is mounted the garage door. The draw bar assembly is to be linearly moved by a draw bar drive which is to be electrically activated when operating of a hand held remote that operates the conventional garage door opening mechanism.
