Abstract:
An active break release device driven by a second motor and externally attached to the door controller, which is used for the triggering of automatic brake releasing to close the safety door in unexpected electricity failure condition, in which the door controller have a housing for receiving a first motor, the driving torque of which is transferred through a rotary shaft to a reel for winding the door; a braking device is provided at the outside of said rotary shaft, which includes a braking portion normally located at a brake activating position, and located at a brake releasing position when the first motor is energized, characterized in that the active break release device comprises: at least a brake releasing rod, one end of which activates the braking portion to release braking by leverage action force, while the other end of which extending to the outside of the door controller; at least a second motor, provided externally at the door controller and moved together with the other end of the brake releasing rod; a circuit having a backup power source used to temporarily supply electricity to the second motor in case of unexpected electricity failure condition, so that the braking portion being driven to release braking. In this manner, the braking can be automatically released at the first instant of electricity failure so as to close the safety door.
Abstract:
A clutch mechanism of the present power device comprises a fixed gear member, a moving gear member engaged with the fixed gear member when moving to a clutch connecting position, an armature for moving the moving gear member to the clutch connecting position when rotated relatively to the moving gear member, an electromagnetic coil unit for applying a brake resistance to the armature, and a clutch holding surface for abutting against the moving gear member when the electromagnetic coil unit is turned off in the clutch connecting state and for holding the moving gear member at a brake-clutch connecting position. The abutment of the moving gear member against the clutch holding surface is released by rotating the moving gear member relatively to the armature in a state in which the electromagnetic coil unit is operated.
Abstract:
A door operator includes a housing; a hydraulic compartment; a pressure compartment; a drive unit disposed in the housing and coupleable to a door via an output shaft, the drive unit being associated with the hydraulic compartment; a hydraulic pump in hydraulic connection with the hydraulic compartment and the pressure compartment; a motor in driving relationship with the hydraulic pump; and a spring force accumulator disposed in the housing. The spring force accumulator is associated with the pressure compartment and coupled to the drive unit.
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.
Abstract:
An operator for use in connection with a door system including an axle having an operator framework supporting an operator motor, the operator framework defining a clearance adapted to insertably receive the axle therein, a gear assembly defining a bore in which the axle is received and including a removable gear segment adapted to selectively medially open the bore to receive the axle, wherein the motor is interconnected with the gear assembly to cause rotation thereof.
Abstract:
Disclosed is an ejection device (1) for a movable part (9) of a piece of furniture. Said election device (1) comprises a lever (2) for transmitting force to the movable part (8) of the piece of furniture. The lever (2) encompasses a lever member (3) which is mounted so as to be rotatable by a limited degree about an axis of rotation while having a free lever end (4). The lever member (3) is provided with a section (9) that is spaced apart from the axis of rotation and the free lever end (4) and is embodied in a curved manner.
Abstract:
A drive system for regulating devices in motor vehicles comprising a housing containing a drive element of the regulating device, a disk armature motor provided with an armature disk, and a planet wheel transmission. The planet wheel transmission comprises an internal geared wheel fixed to the housing and provided with an internal gear, an output internal geared wheel connected to the drive element of the regulating device and provided with an internal gear, and a radially flexible ring, the external gear thereof partially meshing with the inner gears of the internal geared wheel fixed to the housing and of the output internal geared wheel, and the inner envelope surface thereof rolling on rollers arranged on a drive hub connected to the armature disk. A journal pertaining to the output internal geared wheel is centred between the fixed drive axle and a cylinder of the drive hub.
Abstract:
An automatic gate opener lock. The gate opener lock has a locking bolt which is moved between locked and unlocked positions by the movement of a swing arm of an automatic gate opener. To prevent movement of the locking bolt toward its locked position before the gate is closed, springs are arranged for resisting movement in that direction. The springs have a combined resistive force greater than the force required to move the gate. Only when the gate is closed, and the force from the swing arm may no longer be dissipated through gate movement, is the combined force of the springs overcome, and the locking bolt moved into the locked position.
Abstract:
A sliding door system comprising: a transom; at least one door leaf movable along the transom; an endless traction mechanism tension-resistantly connected to the at least one door leaf; a housing supported by the transom; a drive device for driving the endless traction mechanism, the drive device comprising a driven pulley supported by the housing and guiding the endless traction mechanism, the driven pulley having a flange facing the housing, and a locking element on the flange; a complementary locking element supported by the housing; and an electromechanical actuation device received in the housing. The electromechanical actuation device is operable to cause the complementary locking element to abut against the locking element to lock the at least one door leaf relative to the transom.
Abstract:
To provide a movable body driving device which has simple structure and is capable of moving a movable body in a certain direction and automatic drawer equipment. A movable body driving device is provided which comprises a roller 12 as a rotary member which is rotatably supported on an inner frame 11 as a supporting member and a motor 13 for rotating the roller 12. The roller 12 is brought in contact with the movable body, which is adapted to be movable in a certain direction, with predetermined force using elastic force of coil springs 21, 22, 23 as elastic members. The movable body is moved by frictional force between the movable body and the roller 12. Automatic drawer equipment employing the movable body driving device as its drawer driving mechanism is also provided.
