Abstract:
The invention relates to a device for opening of doors. Electromechanical systems contain many expensive components and are thereby expensive to manufacture. Installed electromechanical systems are expensive in operation by virtue of the high and energy-demanding friction which always are present in mechanical constructions. The present operating device is less energy-demanding by the formed transmission of power via two piston-like parts (5 and 6). A driving device (2) is arranged to drive the piston-like part (5) and the second piston-like part (6) is connected to an operable element.
Abstract:
A power window apparatus includes an operation switch for causing a window glass to move when operated. The operation switch generates an input signal having a ground level when operated. A microcomputer drives a motor in response to an input signal. A down terminal and an up terminal are used to connect the operation switch and the microcomputer to each other. A ground terminal is used to connect the operation switch and ground to each other. A battery terminal is used to connect the operation switch and a power supply to each other. When operated, the operation switch connects the down terminal or the up terminal to the ground terminal and generates an input signal having the ground level in the down terminal or the up terminal. When not operated, the operation switch connects the down terminal and the up terminal to the power supply terminal.

Another aspect of the invention provides a door operator with a spring force adjusting member that moves in the generally longitudinal direction of the spring structure. Another aspect of the invention provides a method for adjusting the spring force of the spring structure in a door operator. Another aspect of the invention provides a swing door operator with an adjustable stop member.
Abstract:
An opening flap comprises a frame and a flap articulated thereto. A lift arm is provided, which is articulated by a principal energy accumulator. A secondary energy accumulator is articulated between the lift arm and the flap. The principal energy accumulator delivers the opening motion of the flap into a position before the dead center thereof. The secondary energy accumulator, which is distinctly weaker, delivers the subsequent opening motion.
Abstract:
A notebook computer hinge with spring opener is provided. The shaft has a C-shaped stopper ring with an offset notch in the middle section, which allows the coupling block of the rotatable bracket to be engaged by the notch. A spring is mounted on the outer edge of the rotatable bracket through a common shaft. As the display panel is lowered towards the computer body, the coupling block presses against the stopper ring and a torsional force is accumulated by the spring. The force will be released once the notebook computer is opened, enabling the display panel to be separated from the computer body with an appropriate angle, thus providing extra convenience for notebook computer users.
Abstract:
The invention pertains to a hydraulic swinging-leaf door drive for swinging doors with an actuating piston, which acts on a drive shaft, and with a hydraulic pump, which acts on the actuating piston by way of a hydraulic circuit. To create a hydraulic swinging-leaf door drive of the type explained above, which is improved from a technical standpoint, which occupies only a small amount of space, and which is also suitable for installation under cover, it is provided according to the invention that the hydraulic circuit is designed as a closed circuit.
Abstract:
A device for opening and closing a pivotally mounted door leaf (2) or the like comprises an actuator, which is displaceably and/or rotatingly arranged in a housing (10) and connected to the door leaf and which, during displacement rotation, actuates said door leaf, and a drive motor (27) which is connected to the actuator for providing displacement/rotation thereof.
Abstract:
The present invention consists of a system for automatically lowering power windows and unlatching power door locks of an automobile after an accident. The system is responsive immediately to a vehicle immersion condition or a vehicle fire condition. The system is responsive after a set delay to a vehicle inversion condition or a vehicle impact. A second timer deactivates the system as soon as the doors are unlocked and the windows are at least partly opened following a vehicle impact. The system is advantageous for preventing the entrapment of people in a damaged vehicle, in four of the worst life-endangering situations, without affecting the retention of these people inside the vehicle during the development of the accidents preceding these situations. A diagnostic circuit is also provided for interrogating some of the hazardous condition sensors for the purpose of periodically verifying the integrity of these sensors.
Abstract:
An automated garage door closing device for a remote controlled overhead garage door wherein the device is mounted on one of a pair of parallel tracks receiving rollers suitably mounted on the outer edges of the door panels, the device including a switch housing containing a switch for the leading edge of the door, and a circuit located in a second housing adjacent the garage floor and including an interval timer acting to close the door after a predetermined period of time, an audible alarm which is activated upon the garage door reaching the fully open position, a switch deactivating the entire unit when the garage door is deliberately to be left in the fully open position, and a flexible switch arm extending through the switch housing to a position to engage the upper edge of the garage door panel and acts to activate the automated closing device. A recycle delay circuit in the timing circuit acts to deactivate the unit upon interruption of the door closing operation if door movement is reversed and returned to the open position, and a sensor providing a sensor beam adjacent the garage floor to measure the time interval of interruption of the sensor beam to determine if a vehicle has exited or entered the garage or a person or animal has interrupted the beam. Also, a carbon monoxide detector is inserted in the circuit to provide activation of the door opening cycle if the level of carbon monoxide reaches a dangerous level.
Abstract:
The present application discloses an axial operator that is configured for use with a door assembly. The axial operator comprises a rotatable operator output member that rotates about an operator axis, the operator output member being constructed and arranged to be operatively connected within the door assembly such that the operator output axis extends generally vertically. An electric motor has a rotatable motor output member that rotates about the operator axis. The motor is constructed and arranged to selectively rotate the motor output member about the operator axis. A reduction transmission is connected between the motor output member and the operator output member. The reduction transmission is constructed and arranged such that the transmission rotates the operator output member at a lower rotational speed than a rotational speed at which the motor rotates the motor output member and applies a higher torque to the operator output member than a torque which the motor applies to the motor output member. The reduction transmission comprises (a) an orbit gear, (b) a planet gear carrier, and (c) a planet gear. The motor is adapted to be communicated to a controller so as to receive a door moving signal therefrom and being further adapted to selectively rotate the motor output member in response to receiving the door moving signal to thereby rotate the operator output member so as to move the door panel with respect to the doorway as aforesaid.
