Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic window closing device for automobiles that prevents people from forgetting to close windows, and can be used in combination with automatic window closing devices such as side windows and universal windows. It is possible.

According to the author, the automatic opening/closing device mentioned above has a dedicated switch number for that purpose, and is designed to be operated to close the window when leaving the car. .

Therefore, if you forget to operate the switch, there is a problem that the window will not open.

The present invention aims to solve the above-mentioned problems by providing a second switch and a second switch, which causes the first switch to raise the glass and lower the glass when the lowering contact is closed. In the event that an object that places a load on the glass is caught in the glass during operation, switch 4 opens to prevent danger.

According to the present invention, as a first switch, a p switch 6 which is closed by being removed from a key cylinder is provided as a key switch.
is provided. This switch 6 is the key switch 2
It may be closed in conjunction with bringing the stop position to the stop position. Further, it is manually operated as a second switch in series with this switch 6. A normally closed switch 7 is connected. Reference numeral 8 designates a time limit circuit, which produces an output signal that remains at the energizing level for a predetermined period of time from that point on when the switches 6 and 7 are both closed. This output signal is amplified by drive circuit 9 and applied to relays 1° and 11. The relay 10 is connected in parallel with the above-mentioned key switch 2, and supplies power to the automobile window opening/closing starter 3 even when the key switch 2 is open, while the output signal of the time limit circuit 8 is at the activation level. It has a role. The +■ relay 1 is connected in parallel to the rising contact U of the manual switch 5, and when it is energized and closes that contact, it causes the window glass to rise can be done.

Since this device is constructed as described above, by keeping the manual switch 7 closed, the time limit circuit 8 outputs an energizing level for a certain period of time each time the switch 6 is opened when the user is about to leave the vehicle. Generate a signal and relay 10
．． By pushing 11 upward and closing its contacts, the automatic window opening/closing device 3 can be operated in the raising mode. Therefore, there is no need to close the rising contact U of the manual switch 5 every time the driver leaves the vehicle, and it is possible to prevent the driver from forgetting to close the window glass.

Furthermore, if it is desired to leave the window glass open, the function of the switch 6 can be disabled by leaving the manual switch 7 open.

In addition, as a modification of the above embodiment, switches 6 and 7
It goes without saying that whether the circuit is opened or not can be set arbitrarily depending on the relationship with the time limit circuit 80 input means. In addition, as the switch 7, each time the key switch 2 or the switch 6 is operated to a state indicating the operating state of the automobile, it is temporarily turned into a closed state (closed in the illustrated example), and then is operated to a non-operated state. In such a case, by configuring the switch 7 to maintain this state, it is possible to prevent the user from forgetting to set the switch 7 to the non-operating state.

As described above, the present invention is capable of automatically closing the window when leaving the automobile by operating the automatic window opening/closing device using two switches and a timer circuit.
