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). The emergency opening drive (4") comprises a turbine (13) for generating a rotational movement from the pyrotechnic energy, which works together with a downstream reduction gear (14) to open the passenger door (1).

PROBLEM TO BE SOLVED: To enable fully automatic opening/closing of a trunk lid at low cost without making its device constitution complicated in a trunk lid automatic opening/closing device utilizing a four-point link hinge mechanism.SOLUTION: The trunk lid opening/closing device utilizes a four-point link hinge mechanism constituted with two hinge arms, which face to each other, and two link plates, which also face to each other, being pivotally connected to each other so as to form a ring. An electric actuator extendable automatically is connected to the two hinge arms of the four-point link hinge mechanism in such a manner as to bridge the two hinge arms, and one of the hinge arms is fixed to a trunk lid. The actuator extends and retracts, whereby the four-point link hinge mechanism pivots so as to open/close the trunk lid.
Abstract:
PROBLEM TO BE SOLVED: To provide, at low cost, a drive device pivoting a leap-up flap of a vehicle body. SOLUTION: In the drive device having a drive motor 1 pivotally driving the leap-up flap 5 through a transmission mechanism and pivoting the leap-up flap installed on the vehicle body around the pivot axis thereof, the drive motor 1 can be switched between a driving active state and a non-driving inactive state. The drive motor 1 is so formed that can be rotated in the inactive state at least without causing a strong resistance. A braking device 3 is disposed in the transmission mechanism starting at the drive motor 1 to the leap-up flap 5 so that the transmission mechanism can be blocked by the brake device 3. The braking device 3 is brought into a blocked state when the drive motor 1 is in the inactive state and a non-blocked state when the drive motor 1 is in the active state. The drive motor 1 of non-self locking type is used in this drive device. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
An access control system for restricting access through a passageway includes a shaft rotatable about a central axis; a barrier fixed to the shaft to rotate therewith; and a brake assembly. The brake assembly includes a sun gear rotatable about the central axis, a carrier, and a ring gear, wherein one of the carrier or the ring gear is fixed against rotation and the other of the carrier or ring gear is connected to the shaft to rotate therewith. A plurality of planet gears are rotatably connected to the carrier, each planet gear being disposed between and engaging with each of the sun gear and the ring gear. An electromagnetic brake comprises an electromagnet and an armature. The armature is connected to or integral with the sun gear to rotate and move axially therewith. At least one of the electromagnet or the armature is moveable between an operative position and an inoperative position.
Abstract:
An automatic door operator and a drive mechanism thereof are disclosed. The drive mechanism of the automatic door includes a planetary reducer driven by an electric motor, and a drive shaft driven by a planetary reducer. The planetary reducer includes a housing and a planetary gear train mounted in the housing. The planetary gear train includes a final-stage planet carrier configured to output torque, and a center of the final-stage planet carrier is provided with a torque output hole. A first end of the drive shaft is detachably inserted in the torque output hole and is non-rotatably connected to the torque output hole, and a second end of the drive shaft extends out of the housing. The drive mechanism of the automatic door operator is advantageous to the miniaturization design of the automatic door operator.
Abstract:
A combination door operator assembly and door, wherein the door operator assembly includes an operator unit mounted to the door on the pushing side thereof, an arm linkage having a driving arm and a driven arm, a second mounting bracket preferably on the frame of the door, a rechargeable power storage pack having at least one of a rechargeable battery and one or more capacitors, and a controller, for monitoring a speed and a position of the door, wherein when the door moves faster than a predetermined speed, the motor is used as a generator to charge the rechargeable power storage pack and the speed of the door is reduced.
