Abstract:
The present invention provides a control apparatus for automatic sliding doors that can be used with a plurality of door brands and models. The invention includes a control box and an idler pulley mounted to the door header. Both the control box and idler pulley can be mounted on a variety of door models by means of specific header brackets that are configured for each door model. The control box also provides a universal signal interface that can interpret sensor signals from a plurality of door models. A drive belt revolves on the idler pulley and is moved by a motorized pulley controlled by the control box. At least one belt bracket is fastened to the drive belt with a belt clamp, wherein the belt bracket is attached to a sliding door panel. Like the control box and idler pulley, the belt bracket can be used with a variety of door models and is attached to the sliding panel by means of a door bracket that is specific to the door model in question.
Abstract:
An apparatus is provided in which a motor 11 with reduction gears, a clutch 12 and a gas stay are provided between a vehicle body 2 and a tailgate 1 so that a fully opened position of the tailgate can be held by virtue of a thrust of the gas stay only, and in this apparatus, when a closure of the tailgate from its own weight is detected after the motor with reduction gears is disconnected, the motor with reduction gears is connected to the tailgate to drive to forcibly close it after the tailgate is driven to be opened to the fully opened position thereof. By this construction, when the holding force of the opened position is short, since the tailgate is closed after it is opened to the fully opened position once, cargo loading and unloading work can be completed while the tailgate is so closed.
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.
Abstract:
The present invention relates to automatic door assemblies and swing operators therefor. One aspect of the invention provides a swing door operator that has an opening in the housing thereof for easy access to the operator motor. Another aspect of the invention provides a method for servicing a door operator. 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.
