Main switch 8 can only be operated when front sub switch 7 is not operated. front sub switch 7 takes priority over the opening/closing operation of main switch 8. It looks like this.

[0015] The main switch 8 has a second open drive side contact 8b and a second close drive side contact 8c. The switch body 8a is normally biased toward the neutral position 8d. It is. The opening drive side contact 8b turns on when the large roof body 4 is completely opened. Relay for opening the large roof body 4 via the open limit switch 15 The excitation coil 16a of the switch 16 and the excitation coil 1 of the relay switch 12 described above. 2a. Here, rear open limit The switch 15 is not connected when it is in the off state, that is, when the large roof body 4 is not completely opened. Connect the point 8b to the excitation coil 16a and set it in the on state, that is, the large roof body 4 is completely opened. When the state is reached, the contact 8b is connected to the excitation coil 12a.

[0016] The close drive side contact 8c of the main switch 8 is turned on when the small roof body is completely closed. The large roof body 4 is driven in the closing direction via the front close limit switch 18. the excitation coil 17a of the relay switch 17 for moving the relay switch 1; It is designed to be selectively connected to the No. 3 excitation coil 13a. Here, the flow The engine close limit switch 18 is in the off state, that is, the small roof body 3 is completely closed. When the contact 8c is not turned on, the contact 8c is connected to the excitation coil 17a, and the contact 8c is turned on, that is, the When the roof body 3 is completely closed, the contact 8c is connected to the excitation coil 13a. It looks like this.

[0017] Between the opening drive side contact 7b of the front sub switch 7 and the excitation coil 12a, there is a rear A relay switch 20 is provided which interlocks with the rear close limit switch 23 described below. It is being This relay switch 20 is activated when the large roof body 4 is completely closed (reset). When the mitt switch 23 is off), the contact 7b is directly connected to the excitation coil 12a. and the large roof body 4 is not completely closed (limit switch 23 is on). state), the excitation coil 12a is connected via the tilt up limit switch 21. This is a switch to continue. Tilt up limit switch 21 is small roof This switch is turned off when the body 3 is completely tilted up.

[0018] Also, the excitation coil 12a of the relay switch 12 is tilted up when the small roof body 3 is tilted up. Front open limiter that slides out and turns off when fully opened It is grounded via switch 22. Furthermore, the excitation coil 1 of the relay switch 17 7a is a rear close limiter that turns off when the large roof body 4 is completely closed. It is grounded via the switch 23.

[0019] Next, each stage of the small roof body 3 and the large roof body 4 is The opening/closing operation by the switch will be explained.

[0020] First, both roof bodies are completely closed and switches 7 and 8 are both in the neutral position. From a certain state, the main switch 8 is operated slightly to the open side (point A). Then the relay The switch 16 is turned on, and the large roof body 4 is slightly driven toward the open side by the motor 6. , the rear close limit switch 23 is turned off.

[0021] Next, return the main switch 8 to the neutral position and turn the front sub switch 7 to the open side. When operated (point B), the relay switch 12 is turned on, and the motor 5 turns on the small loop. Body 3 tilts up. Then, the rear close limit switch 23 is turned off. The relay switch 20 linked to this switch controls the front sub The contact 7b of the switch 7 is connected to the relay switch via the tilt up limit switch 21. Since it is connected to the excitation coil 12a of the switch 12, the tilt up limit switch is When the switch 21 is turned off (point C), the relay switch 12 is turned off. On the contrary, When the front sub switch 7 is operated to the close side (point D), the relay switch 13 is turned on. Then, the small roof body 4 is tilted down by the motor 5.

[0022] Next, when the main switch 8 is operated to the close side (point E), the relay switch 17 is activated. is turned on, the large roof body 4 is closed, and the rear close limit switch 23 is turned on. (point F), and the relay switch 17 is turned off.

[0023] Next, when the front sub switch 7 is operated to the open side (point G), the relay switch 12 is turned on, and the small roof body 3 is first tilted up. At this time, the large roof When the body 4 is completely closed, the relay is linked to the rear close limit switch 23. Switch 20 connects contact 7b of front sub switch 7 directly to relay switch 1. Since it is connected to the excitation coil 12a of No. 2, the small roof body 3 can be tilted up. After that, slide continuously in the opening direction. Then, the small roof body 3 is completely opened. In this state, the front open limit switch 22 is turned off, and the relay switch 12 is turned off. is turned off (point H).

[0024] Here, from point G to point H in FIG. 3, more precisely, the front sub switch 7 During operation, make sure that the switch body 7a of the front sub switch 7 is not at the neutral contact 7d. Even if the main switch 8 is operated from then on, each roof body will not be driven.

[0025] From this state, when the front sub switch 7 is operated in the closing direction (point I), the small loop After the cover body 3 slides in the closing direction, it tilts down.

[0026] Next, with the front sub switch 7 at the neutral contact 7d, the main switch 8 When operated in the opening direction (point J), the rear open limit switch 15 The relay switch 16 is turned on, and the motor 6 drives the large roof body 4 in the opening direction. . Then, when the large roof body 4 is completely opened (point K), the rear open limit switch is activated. switch 15 is turned on, and contact 8b is connected to the excitation coil 12a side of relay switch 12. Continued. That is, at the same time as the large roof body 4 stops, the motor 5 causes the small roof body 3 to tilt. Raise it up and slide it further to the open side. Then, the small roof body 3 is completely opened. The front open limit switch 22 is turned off and the relay switch 12 is turned on. (point M). At this time, while operating the main switch 8 to the open side, simultaneously open the main switch 8. When the front sub switch 7 is operated to the close side (L point), the fluorocarbon is turned on only while the front sub switch 7 is operated. The operation of the sub-switch 7 is prioritized, and the small roof body 3 is driven in the closing direction.

[0027] While holding the switch body 7a of the front sub switch 7 at the neutral contact 7d, When the front close limit switch 8 is operated to the close side (point N), the front close limit switch The switch 18 causes the contact 8c of the main switch 8 to connect to the excitation coil of the relay switch 13. 13a, the small roof body 3 is driven in the closing direction and tilted. When the small roof body 3 is completely closed (point O), the front close limit is reached. The switch 18 connects the contact 8c to the excitation coil 17a of the relay switch 17. This drives the large roof body 4 in the closing direction. Then, the large roof body 4 is completely In the closed state (point P), the rear close limit switch 23 is turned off and the relay switch is turned off. The switch 17 is turned off and the motor 6 is stopped.

[0028] As mentioned above, normally operate the main switch 8 to the open or close side. When operating the opening side, slide the large roof body in the opening direction and then tilt the small roof body. When the roof is closed, the small roof body is Slide the large roof body in the closing direction, then tilt it down and slide the large roof body in the closing direction. You will be able to do it.

[0029] Also, when the front sub switch 7 is operated to the open side, the large roof body 4 is completely closed. In this state, the small roof body can be tilted up by operating the front sub switch 7. After opening the roof, slide it in the opening direction, but if the large roof body 4 is even slightly open, the small Only tilting up/down of the roof body 3 is possible.

[0030] Here, if the operation of the front sub switch 7 is interrupted during the operation of the main switch 8, However, while operating the front sub switch 7, the main switch 8 It is not possible to interrupt the operation.
