Similarly to the above, the rear operation switch 13 also includes a first operation switch 31r and a second operation switch 32r that open and close the sliding roof 3, respectively.
The first operation switch 31r has a normally open contact 31ra, a normally closed contact 31rbJ, and a movable contact 31rC, and the second operation switch 32r has a normally open contact 32ra.

It has a normally closed contact 32 rb and a movable contact 32 rc. - In the front operation switch 12, the first operation switch 31
The motor 11 is connected between the movable contact 31fc of f and the movable contact 32 (C) of the second operation switch 32f, while the first operation switch 31f and the second operation switch 3
The normally open contacts 31fa and 32fa of 2f are both '
A key switch 34 is connected to the positive electrode of the battery 33 whose negative electrode is grounded.
It is connected to a power supply line 35 connected through.

On the other hand, in the rear operation switch 13, the normally open contact 31ra and the normally closed contact 31r of the first operation switch 31r
b are connected to the power line 35 and the ground, respectively, and a normally open contact 32 ra and a normally closed contact 32 rb of the second operation switch 32r are connected to the power line 35 and the ground, respectively.

Between the movable contact 31rC of the first operation switch 31r of the rear operation switch 13 and the normally closed contact 31tb of the first operation switch 31f of the front operation switch 12, there is a normally open contact X of the relay X1 of the temporary stop circuit 14. Connect a, and
The movable contact 32rc of the second operation switch 32r of the rear operation switch 13 and the normally closed contact 32tb of the second operation switch 32f of the front operation switch 12 are connected to each other.

Although not specifically illustrated as the above-mentioned front operation switch 12 and rear operation switch 13, for example,
A knob swingably supported on a support shaft is normally in a neutral position, and a well-known scene-type switch can be used in which the end of the knob is pressed to perform a necessary operation.

Next, the negative stop circuit 14 consists of relays XI, X2 and diodes D, D2.

The relay coil x0 of the relay x1 (hereinafter, the relay and the relay coil are denoted by the same symbol) is connected between the power line 35 and the normally open contact 15a of the position detection switch 15, while the relay coil x0 of the relay The coil X2 and the normally open contact x2-a of the relay x2 are connected in series between the power supply line 35 and the normally closed contact 15b of the position detection switch 15.

□ Relay coil X and normally open contact 1 of position detection switch 15

The anode and cathode of the diode D0 are connected to the connection point 37 between the contact point 37 and its normally open contact The anode and cathode of the diode D2 are connected to the connection point 38 with the contact 32fc, respectively.

The movable contact 15C of the position detection switch 15 is connected to ground.

Next, the operation of the circuit shown in FIG. 5 will be explained.

Now, the sliding roof 3 is fully open, the movable contact 15C of the position detection switch 15 is connected to the normally open contact 15a, the key switch 34 is on, and the front operation switch 12 and rear operation switch 13 are Assuming that none of them are operated, position detection switch 1
Since the movable contact 15C of No. 5 is connected to the normally open contact 15a side, the relay X0 is on and normally open, the contact X□-3 is on, and both of the motor 11 - The machine is stopped in the same state.

In the above state, for example, by operating the second operation switch 32f of the front operation switch 12, as shown by the dotted line in FIG.
When the movable contact 32fc is connected to the normally open contact 15a side, the connection point 38 is connected to the power supply line 35, so the voltage of the battery 33 is applied to the motor 1, and the motor l
rotates and the sliding roof 3 starts to close.

Further, when the connection point 38 is connected to the power supply line 35, the diode D2 is turned off, the relay X2 is turned off, and its normally open contact X2-a is also turned off.

By continuing the operation of the second operation switch 32f of the front operation switch 12, the distance g between the front end 3a of the sliding roof 3 and the front edge 2b of the opening 2 of the roof 1 becomes
As explained in FIG. 4, when the position reaches 20, the movable contact 15c of the position detection switch 15 switches to the normally closed contact 15b side, as shown by the dotted line in FIG.

By the way, at this time, relay X2 is off and its normally open contact X2-a is off, so diode D is also off and relay X is off.

Therefore, the normally open contact x1□a of the relay X is turned off, the motor 1 is stopped, and the sliding roof 3 is stopped.

As long as the operation of the second operation switch 32f is continued, the relay X2 is turned off and the sliding roof 3 remains in the stopped state, thereby ensuring the safety of the occupants.

Therefore, once the operation of the second operation switch 32f is interrupted, the movable contact 32fc changes to the normally closed contact 32.
tb side, the connection point 38 is connected to ground, the diode D2 is turned on, the relay 5 is turned on, and its normally open contact x2-a is also turned on, causing the relay X2 to hold itself.

In addition, by turning on the normally open contact x2-a, relay
is also turned on, and its normally open contact x1□a is also turned on again.

Therefore, in the above state, when the second operation switch 32f of the front operation switch 12 is operated again and its movable contact 32fc is connected to the normally open contact 32fa side, the motor 1°1 is connected to the normally open contact x1- of the relay X0. Since a is on, it rotates again and closes the sliding roof 3.

If the above-mentioned re-operation of the second operation switch 32f is continued for a certain period of time, the sliding roof 3 is fully closed.

The second operation switch 32r of the rear operation switch 13 is also operated in the same manner as above.

The roof 3 can be fully closed in two stages.

Next, when opening the sliding roof 3, the second operation switch 32f of the front operation switch 12,
The movable contact 32fc is connected to the normally open contact 32fb, and the second operation switch 32r of the rear operation switch 13 has the movable contact 32rc connected to the normally closed contact 32rb, and the connection point 3
8 is always connected to ground, so relays x 2 and x
2 are movable contacts 15C of the position recess switch 15.
Regardless of the position of (, is always on.

Therefore, the normally open contacts X1-a and X of the relays Xli and If the movable contact 31fc of the first operating switch 31f is set to the normally open contact 31fa side, or the movable contact 31rc of the first operating switch 3if of the rear operating switch 13 is set to the normally open contact 31ra side,
The motor 11 rotates in the opposite direction to the case in which the sliding roof 3 is operated to close, and the sliding roof 3 is stopped midway (and operated to open).

As described above, the sliding roof 3 can be closed with two operations of a single switch, and the safety of the occupants can be ensured.

Next, a circuit diagram of another embodiment of the present invention is shown in FIG.

The embodiment of FIG. 6 uses a relay x0 of the temporary stop circuit 14 in the embodiment of FIG.
Instead of the normally open contact X-a of the relay x2 in FIG. 5, the normally open contact X1 aZ of the relay・,, while connecting, short-circuit the connection point and 37, and connect diode D0 and relay 5.

and is deleted.

In the case of the circuit shown in FIG. 6, when the sliding roof 3 is closed, when the interval g shown in FIG. Hasome normally open contact X 1 a
If the switching time from ON to OFF of 2 is made sufficiently shorter than the switching time of the position detection switch 15, relay X0 is deenergized and its normally open contacts X knee a i J3 and X l a2 are Both are turned off and the motor 11 is stopped.

To rotate the motor 11 again, if you stop operating the second operation switch 32f of the front operation switch 12 or the second operation switch 32r of the rear operation switch 13,
Connection point 38 is connected to ground to provide self-holding to relay X0 and its normally open contacts X□-3□ and
Both a2 are turned on, and if the second operating switch 32f or 32r is operated again in this state, the motor 11 will rotate again and the sliding roof 3 will be closed.

If sliding roof 3 operates to open, go to connection 3.
8 is connected to ground, the motor 11 will perform exactly the same operation as the circuit of FIG.

As described above, the circuit shown in FIG. 6 also allows the sliding roof 3 to be closed in two stages.

Although the above explanation has been based on basic embodiments of the present invention, the present invention is not limited to the above embodiments, and various configurations may be made within the scope of the gist of the present invention. can.

For example, the position of the sliding roof 3 is
It can also be detected by the stroke amount of the motor 11, the rotation speed of the motor 11, etc.

As is clear from the detailed description above, the present invention
A normal switch with a simple contact configuration is used as an operation switch in combination with a relay to stop the sliding roof below the set opening, and the off signal from the operation switch turns on the relay again to allow the motor to rotate. As a result, the operation switch mechanism and contact configuration are simple, allowing the use of inexpensive operation switches. However, in order to fully close the sliding roof, it is necessary to interrupt the operation of the operation switch and then repeat the same operation again. This will greatly improve the operability when fully closing the sliding roof.
