Abstract:
A circuit is provided to ensure that even when a drive circuit system for a power window is wetted with water due to the entering of water or the condensatin of water, the opening and closing of the power window can be performed without hindrance. Coils of an opening relay and a closing relay are selectively connected at one end thereof to a power source or ground through a control switch and at the other end to the power source or ground through an electronic circuit which has been subjected to a water-proofing treatment. Even if leakage current flows from a high-potential portion of the coils to ground, the leakage current is caught by electric current flowing from the power source. In addition, even if leakage current flows from the power source to a lower-potential portion of the coils, the leakage current flows to ground without passing through the coils. Therefore, the unintended excitation and de-excitation of the coils can be prevented to thereby reliably open and close the power window.
Abstract:
A method is disclosed for selective alteration and control of door movement modes utilizing an apparatus that is primarily non-hydraulic and incorporated with a known mechanism which is functional independently from the apparatus in one mode of operation and which includes a piston for controlling door closing characteristics by selected fluid flow within the mechanism. The apparatus includes a motor driven lead screw having a linearly movable shuttle unit mounted thereon, the shuttle unit being positioned relative to the piston of the mechanism to accommodate nonattached contact with the piston to urge the piston, when the shuttle unit is moved, in a direction that will at least provide selective assistance with door opening in another mode of operation. Operation of the apparatus is controlled by programming of a related controller including non-volatile memory.
Abstract:
A carbon monoxide sensing system is provided including a garage having an automatic door adapted to open only upon the receipt of an activation signal. Further provided is a carbon monoxide sensor positioned within the garage and connected to the automatic door for transmitting the activation signal upon the detection of an amount of carbon monoxide which exceeds a predetermined amount. A light beam detector is adapted to generate the activation signal only upon the detection of vehicle within the garage. Also included is a control mechanism connected between the carbon monoxide sensor, light detection and the door opener for allowing the transmission of the activation signal to the door opener only upon the receipt of the activation signal from the light beam detector.
Abstract:
Wall members (1) of a partition wall which can be assembled by roller cross-heads (1a, 1b), along a main guide rail (3-3a) and branch rails (3b, 3c) of displaceable wall members (1) are displaced (A, B, C) by self-propelling trolleys (2, 2a, 2b) which move inside a continuous channel provided in or on the guide rails (3-3a, 3b, 3c). The self-propelling trolleys (2, 2, 2b) have an electrical linking device (4) which acts on suspension projections (6) or recesses provided on the roller cross-heads (1a, 1b). One of the roller cross-heads (1a, 1b) of the wall members is mounted to be displaceable horizontally (1i), to move the sealing ledges (1d, 1e) in and out (1f, 1v) by way of a system of levers, connecting rods, and springs (1t, 1p, 1l, 1n, 1r, 1o).
Abstract:
A portable remotely controlled automatic door closing apparatus enables the door of a room or office to be closed from a remote location within the room or office by transmitting a signal to an actuator which exerts a force on the door to move it from an opened position to a closed position. The apparatus comprises a battery or AC powered motor which moves a lever arm into engagement with the door to rotate the door about its hinges from the open to the closed position. The apparatus is free standing and immobilized on the floor in a non-connected relationship thereto between an adjacent wall and the door in its open position. The apparatus is immobilized to prevent slipping by a floor-engaging mechanism, such as an adhesive, an anti-skid rubber material, or suction cups, or carpet engaging projections.
Abstract:
A remotely controllable door operator system permitting active and passive use of a door includes a transmitter, a receiver, a master timing sequencing mechanism, a clutch-regulated prime mover that can actively move the door, and a mechanism that senses whether the door is fully closed. The door operator is controllable by depressing a single button on the transmitter, which sends a signal to the receiver. If the sense mechanism determines the door is fully closed, the receiver causes the timing mechanism to cause the prime mover to disengage the door latch and to commence actively opening the door for a first time period. The timing mechanism may be user adjusted to control the extent of the door opening by adjusting the length of the first time period.
Abstract:
A friction wheel door drive for a sliding door for lifts consisting of at least one rectilinearly or curvilinearly moved door leaf (1), which is suspended of guide rollers (3) and is guided at a guide (2) is presented. At least one of the guide rollers (3) is formed as a motor roller (3') moving the door leaf and in the form of an outside rotor motor. The motor may be either a direct current motor with permanent magnets in the outside rotor and electronic commutation or a polyphase induction motor with a laminated outside rotor having a short-circuited winding and a laminated inner stator with a polyphase alternating current winding. Force transmission between the motor roller (3') and a running roller (3") may be provided by a transmission (18), between motor roller (3') and running roller (3") is possible.
Abstract:
A window regulator system generally comprises a first pinion rotatably driven by a motor. The first pinion is mounted between a first rack and a rotatable second pinion. The second pinion is rotatably mounted between the first pinion and a second rack. Teeth on the first pinion engage the first rack and simultaneously drive the second pinion to engage the second rack.
Abstract:
A manual to power controller suitable for a vehicle door such as preferably a sliding door comprises a direct-current electric motor for power-moving the vehicle door, and at least one door movement detection circuit for detecting both a magnitude and a direction of an electromotive force induced in a coil of the DC motor. The induced electromotive force results from a movement of the vehicle door relative to the vehicle body with the motor de-energized. Also provided is a microcomputer for rotatively controlling the motor in a desired rotational direction depending upon both the magnitude and the direction of the induced electromotive force to power move the vehicle door with the motor energized.
