Abstract:
A door closer structure includes a door shaft, a housing, a sliding member, a door-closing spring, a claw, an abutting member and a door-opening spring. The door shaft is utilized to drive a sliding member in a housing, between an end of the sliding member and the housing the door-closing spring is tensioned, and another end of the sliding member is engaged with the abutting member and a sliding board respectively in turn, between the sliding board and the housing a door-opening spring and a claw are disposed respectively, the claw is position-locked on the sliding board, and which can be locked and fastened to the adjustable rod of the housing. The abutting member may be driven by the sliding member so as to unlock and release the claw from the inner side of it.
Abstract:
A controller has a plurality of control units that are mutually connected by a communication line and are set at different places of an automobile, each corresponding to a different one of its power windows and serving to control its opening and closing. One of these control units is adapted to transmit a signal, in response to a switch operation, to another of the control units through the communication line to open or close the window corresponding to the latter control unit. When this control unit detects that it has submerged in water, it applies a constant voltage to an interface of the communication line. This prevents communications through the communication line and windows from moving in an unwanted manner.

Abstract:
A auxiliary vehicular window recessing system for providing a secondary means of recessing the electrically-controlled windows of a vehicle in the event of submergence in a body of water. The auxiliary vehicular window recessing system includes a secondary motor for moving the window of the vehicle. A secondary gear member driven by the secondary motor is engaged with the main drive gear such that rotary motion of the secondary gear member biases the primary window drive system thereby recessing the window when the secondary motor is activated. An auxiliary, waterproof battery provides power, while a sealed fuse electrically protects the secondary motor. Optionally or in conjunction, a manual crank apparatus engages the primary window drive system for manually recessing the window.
Abstract:
The present invention provides a power window apparatus that, even if a CPU (IC2) causes malfunction or becomes uncontrollable upon submergence, can prevent windows from performing unexpected operations and enables the windows to be opened without fail if desired. The power window apparatus comprises: a driving part that has two current input-output ends, and opens or closes automobile open/close parts, depending on the direction of a flowing current; two relays which respectively have exciting coils and switching contacts, wherein, when a current is fed to the exciting coils, the switching contacts connect the current input-output end to a positive or negative pole of power; a submergence detecting sensor that drops in resistance value between both ends thereof when exposed to water; and a submergence-time escape switch that forcibly drives the open/close parts open upon submergence, wherein transistors are provided which are connected in series with the exciting coils and feed a current to the exciting coils, and the bases of the transistors are grounded via the submergence detecting sensor.
Abstract:
A power window apparatus capable of opening a window or windows of a submerged automobile by manually operating a driver seat window open switch or a passenger seat window open switch both located on a driver seat window operation unit. The driver seat window operation unit and passenger seat window operation units have each a window close switch, a window open switch, a window open/close motor, and a motor drive controller. The driver seat window operation unit has a submersion detector for generating a submersion detection signal, a motor drive controller incorporating a control driver for opening windows when the driver manually operates corresponding window open switches, and connection lines for connecting normally close contacts of passenger seat window open switches located on the driver seat window operation unit with the normally close contacts of the window open switches located on the passenger seat window operation units.
Abstract:
A device for automatically controlling the operation of a sliding door for a vehicle, the sliding door being mounted on a side of the vehicle body so as to automatically be operated by a driving source such as a motor and freedom and safety incompatible with each other being able to be controlled, the device comprising a door driving portion having a motor rotatable in forward and reverse directions, motor load detector for detecting the load of the motor, door position detector for detecting a door position within a range from a fully opened position to a fully closed position, door speed detection for detecting the travelling speed of the door, a storage device storing the load of the motor when the vehicle body is in a normal posture as a specific load of the motor associated with the position of the door by correlating the motor detector with the door position detector and motor controller for controlling electric power supplied to the motor while detecting a motor speed, by a deviation between a motor load stored for a specific door position and a motor load for driving the door at that position.
Abstract:
An automatic door operator for swing doors which uses a worm gear transmission to connect the motor to a belt and pulley which in turn is connected to a spur gear and drive gear. The door arm of the swing door is connected to a double-ended shaft which is part of the drive gear. A rack and pinion gear and spring are used to provide the closing force to the door arm. The motor is mounted over the spring and the belt and pulleys are located alongside the motor which results in a compact non-handed design.
Abstract:
When a window lowering switch is operated, a car voltage is supplied to a window lowering relay to drive the window lowering relay, and the window lowering relay is inhibited from being driven by supplying an inverse voltage to a window elevating relay. Thus, there is provided a waterproof power window device in which a window may be opened by operating the window lowering switch (3) even when a car falls in the water and is laid under water.
