Is housed in a tube 110 fixed to the base 91a or the like of the unlocking operation tool 9A. The same applies to the other unlocking operation tool 9B. In FIG. 4, reference numeral 94b denotes a handle, 100B denotes an auxiliary wire, and 110 denotes a tube.

The operation will be described. Both winding tools 6A, 6
It is assumed that the lock mechanisms 8 and 8 of B are set to the locked state described with reference to FIG. 6, and the skylight 2 is fully closed as shown in FIG. At this time, the main wire 7 having a length necessary to fully open the skylight 2 is wound around each of the drums 62a and 62b of the winding tools 6A and 6B.

There are the following four methods for opening the skylight 2 in this state. The first is a method of pressing down the operation button 87 of the lock mechanism 8 provided on the one winding device 6A, and the second is a method of pressing down the operation button 87 of the lock mechanism 8 provided on the other winding device 6B. Third, the handle 94 of one of the unlocking operation tools 9A is used.
This is a method in which a is pushed down like a virtual line in FIG.
Is a method in which the handle 94b of the other unlocking operation tool 9B is moved forward.

According to the first method, the lever 85 of the lock mechanism 8 which has been set to the locked state in FIG. 6 moves forward about the shaft 83 as shown by the arrow Y in FIG. The ratchet claw 84 is the tooth 8 of the ratchet wheel 81
1a, the state is switched to the unlocked state as shown in FIG. For this reason, the drum 62a of the one winder 6A
The main wire 7 wound up is drawn out from the drum 62a by an elastic force of the spring body 3 as shown by an arrow b, and the main wire 7 extending between the two winding tools 6A and 6B is accordingly moved. The length of the window 7 gradually increases, and the skylight 2 is opened by the elastic force of the spring body 3. At this time, the operation button 87 is pushed up while the skylight 2 is being opened, and the lever 8 is opened.
5 is moved back as indicated by an arrow X, whereby the locking mechanism 8 is moved.
Is switched to the locked state in FIG. 6, the main wire 7 is no longer fed at that time, and the skylight 2 is held at the opening angle at that time. In the unlocked state shown in FIG. 7, the force of the spring 88 moves the lever 85 forward (arrow Y).
In the locked state shown in FIG. 6, the force of the spring 88 acts in the direction to move the lever 85 back (arrow X), so that the lock is released unless the position of the lever 85 is changed artificially. The state and the locked state are maintained as they are. The same applies to the case of the second method.

According to the third method, the auxiliary wire 100A connected to the handle 94a is pulled by tilting the handle 94a of the unlocking operation tool 9A forward as shown by the imaginary line in FIG. 6, the lever 85 of the lock mechanism 8 set in the locked state moves forward about the shaft 83 as indicated by an arrow Y. Therefore, as described in the first method, the lock mechanism 8 is switched to the unlocked state, and the one winding tool 6A
The main wire 7 wound around the drum 62a is fed by the force of the spring body 3 from the drum 62a as indicated by an arrow b, and the skylight 2 is opened. When the lock mechanism 8 is switched to the unlocked state shown in FIG. 7 by tilting the handle 94a forward, the force of the spring 88 moves the lever 85 backward (arrow X).
The lock mechanism 8 maintains the unlocked state as it is in the direction in which the lock is made. Therefore, in a case where the skylight 2 must be fully opened in order to promote smoke evacuation even when evacuation is urgent such as in the case of a fire, the driver immediately leaves the place after the handle 94a is moved down. Even if the evacuation is performed, there is an advantage that the skylight 2 is fully opened automatically and smoke is quickly exhausted. The same applies to the case of the fourth method. When the operation button 87 attached to one of the winders 6A is pushed up and the lever 85 is moved back (arrow X) while the skylight 2 is being opened, the locking mechanism 8 is turned on as shown in FIG. , And the skylight 2 is held at the opening angle at that time.

The lock mechanisms 8, 8 of both winding tools 6A, 6B are set to the locked state described with reference to FIG.
There are the following two methods for closing the skylight 2 when the skylight 2 is open. The first is one winding tool 6A
Turn the handle 64a of the drum 62a to connect the main wire 7
The second method is to rotate the handle 62b of the other winding tool 6B to rotate the drum 62b in the winding direction a of the main wire 7.
With either of these methods, both winding tools 6A, 6A
The length of the main wire 7 between B is gradually reduced, and the skylight 2 is pulled by the main wire via the pulley 51 and gradually closes. At this time, if the winding of the main wire 7 is stopped while the skylight 2 is being closed, the skylight 2 is maintained at the opening angle at that time.

In the skylight opening / closing device described above, two winding tools 6A and 6B and two unlocking operation tools 9A and
If the 9B is separately installed on different floors or different rooms of the house, the operation of opening the skylight 2 can be performed at the place where one of them is installed, and the two winders 6A, The operation of occupying the skylight 2 can be performed at a place where any one of 6B is installed. Therefore, the opening and closing operation of the skylight 2 can be performed extremely conveniently.

FIG. 9 is a schematic perspective view of a skylight opening / closing device according to a second embodiment of the present invention, and FIG. 10 is an exploded perspective view of a main part of the skylight opening / closing device according to the second embodiment. In this embodiment, only one winding tool 6A and only one unlocking operation tool 9A corresponding to the winding tool 6A are provided, and one end of the main wire 7 is connected to the skylight frame 1. The only difference from the above-described embodiment is that the other end 7b of the main wire 7 is fixed to the bracket 71b (see FIG. 3). The configuration of the winding tool 6A and the lock release operating tool 9A is the same as that described above. With this configuration, the skylight 2 can be opened at the two locations by installing the winding device 6A and the unlocking operation device 9A at different locations.
In FIGS. 9 and 10, for simplification of description, the same portions as those described in FIGS. 1 and 4 are denoted by the same reference numerals, and description thereof is omitted.
