Abstract:
The invention relates to a device for opening a passenger door (1) of an aircraft in case of emergency, which is fastened so it is manually pivotable on the fuselage (3) of the aircraft via a hinge and/or support arm configuration (2), an auxiliary-energy-operated emergency opening drive (4) being provided between the fuselage (3) and the passenger door (1), which automatically opens the passenger door (1) in accordance with an emergency control unit (5), the auxiliary energy for the emergency opening drive (4) being pyrotechnic energy, whose gas expanding inside an expansion chamber (6) after triggering by the emergency control unit (5) impinges the emergency opening drive (4) with pressure medium to open the passenger door (1), wherein said emergency opening drive (4) generates a rotational movement.
Abstract:
The invention relates to a door drive with a motor-gear-unit and with a spring (7), which acts as an energy accumulator. With the intention to provide a door drive, in which, through the exchange of a single structural component, two variants for scissor arm assemblies, respectively slide channel arm assemblies are realized, according to the invention, it is provided that the pre-loading of the spring (7) can be actively changed by the motor-gear-unit, whereby the desired closing moment characteristics are generated.
Abstract:
A mechanical arm system for opening a door includes an actuator assembly having an output shaft and an arm driven by the output shaft so as to move the door from a closed position toward an open position. The arm is free from contact with the door when the door moves from the open position to the closed position. The actuator assembly is mounted to a support member adjacent the door. The arm extends between the output shaft and the door. The arm may be moveable between a position in which the arm contacts the door in the open position and a retracted position in which the arm is free from contact with the door in the closed position. The arm may be moved to the retracted position before the door reaches the open position so as to abort the opening of the door.
Abstract:
A ventilating system for a garage is provided. The ventilating system comprises an automatic garage door opening mechanism and a hazardous gas detector. The automatic garage door opening mechanism is configured for wireless communication and to move a garage door between an open position and a closed position. The hazardous gas detector is configured for wireless communication and to sense the presence of a hazardous gas within the garage. The hazardous gas detector wirelessly instructs the automatic garage door opening mechanism to move the garage door to the open position when the hazardous gas reaches a predetermined level in the garage. As such, the garage is ventilated.
Abstract:
A system for use with a emergency exit door, comprising: a door opener including a stationary actuator with a movable distal arm for pushing the door open; a door strike mountable to a door frame having an opening to receive a latch of the emergency exit door, the electric door strike including a gate having a locked condition and a release condition; a controller connected to the door opener and the door strike; a remote activator having a triggered condition, which provides a signal to the controller when the remote activator is triggered, to unlock the gate and then the door opener, to open the emergency exit door.
Abstract:
A device for opening and closing a pivotally mounted door leaf including an actuator, which is displaceably and/or rotatingly arranged in a housing and connected to the door leaf and which, during displacement/rotation, actuates the door leaf, and a drive motor which is connected to the actuator for providing displacement/rotation thereof.
Abstract:
A system for operating an automotive liftgate includes a motor drive adapted for positioning the liftgate, and at least one telescopic strut positioned between the liftgate and an adjacent body structure. A controller operates the motor drive so as to place the liftgate in a predetermined position, such as a fully closed or fully opened position, in the event that a sensor detects unintended movement of the liftgate.
Abstract:
A vehicle closure hinge includes a mount having a pivot axis flange, a pivot link, a pivot coupling the pivot link to the pivot axis flange and a spring formed by a laterally coiled strand extending from a first coil end to a second coil end in a direction substantially perpendicular to the plane of displacement about the pivot axis. The coil size, the strand size and the number of coils can be varied as desired to vary the spring biasing force exerted against the vehicle closure without varying other components of the hinge. The hinge parts may be designed with various configurations including simple pivoting links or a four bar linkage. A strand end of the coil spring extends along the direction of the coil to a position at a first coil end to maintain biasing force near the plane of displacement about the pivot axis.
Abstract:
When a slide door stops at an intermediate position over a protection action time start time (Tβ), an electric motor is operated in closing direction in low driving force mode. When the move speed (Vc) of the slide door is a movable speed (Vα) or higher, the slide door is moved to its fully closed position by automatic closing action, and an electromagnetic clutch is disconnected. On the other hand, when the move speed (Vc) of the slide door is not made to reach the movable speed (Vα) or higher over a speed judgment time (Tj), the electric motor is operated in closing direction in the low driving force mode, and when the move speed (Vo) of the slide door is made to reach the movable speed (Vα) or higher, the slide door is automatically opened. Further, when the move speed (Vo) of the slide door is made to reach the movable speed (Vα) or higher for the speed judgment time (Tj), the electric motor is stopped, and the electromagnetic clutch is made into its disconnected status.
