At this time, the electric driver 35 is energized, and the operating rod 39 extends against the spring force of the first spring member 48. Therefore, if the upper end portion 18 b of the lock pivot shaft 18 protruding from the upper wall 17 of the mounting box 11 is pressed with a finger, the lock pivot shaft 18 resists the spring force of the second spring member 49. The lower end 18c of the lower end 18c passes through the shaft hole 10 formed in the other end 8b of the opening angle restricting arm 8, and the lower engaging hole 31 of the engaging piece 25 is then pushed. Engage with. At this time, as soon as the flange portion 18a slidably contacting the vertical guide portion 45 of the stopper piece 41 reaches the position of the lower surface of the horizontal engagement frame portion 44, it moves horizontally with the operating rod 39 by the spring force of the first spring member 48 (see FIG. 4, the stopper piece 41 moved to the right) engages the flange portion 18 a of the locking pivot shaft 18.
[0019]
Therefore, the opening angle regulating arm 8 locked to the lower end portion 18c of the lock pivot shaft 18 cannot be removed from the mounting box 11. If the wind collecting window 1 is now opened, the wind collecting window 1 is opened. 1 rotates and opens to a predetermined angle with the pivot shaft 18 for locking as a fulcrum.
[0020]
On the other hand, FIG.7 and FIG.8 is a case where the electric drive body 35 will be in a non-energized state, for example in emergency (fire etc.). At this time, the operating rod 39 of the electric driving body 35 contracts due to the spring force of the first spring member 48. Since the stopper piece 41 moves horizontally together with the operating rod 39 as described above, the distal end portion of the horizontal engagement frame portion 44 moves away from the flange portion 18a of the locking pivot shaft 18. Then, as soon as the horizontal engagement frame portion 44 is separated from the flange portion 18a, the locking pivot shaft 18 is raised by the spring force of the second spring member 49, and the lower engagement hole 31 and the opening angle of the engagement piece 25 are increased. It leaves | separates from the shaft hole 10 of the use control arm 8. Then, the raised lock pivot shaft 18 stops at a predetermined position when the collar portion 18 a abuts against the inner surface of the mounting box 11. At this time, the upper end portion 18 b of the lock pivot shaft 18 protrudes from the upper wall 19 of the mounting box 11, and the other end portion 8 b of the opening angle regulating arm 8 is later inserted into the mounting box 11 through the insertion / removal port 21. When inserted, it becomes a push-in operation unit.
[0021]
Therefore, if the wind sampling window 1 is opened to be fully opened, the other end portion 8b of the opening angle regulating arm 8 comes out of the insertion / removal port 21 of the mounting box 11 as shown in FIG. 1 can be fully opened.
[0022]
【Example】
In the first embodiment, the removal / insertion port 21 of the mounting box 11 should desirably be formed in a plane U-shape, but can also be formed in a plane angle, for example. Further, the lock pivot shaft 18 is engaged with and disengaged from the stopper piece 41 through the flange portion 18a. However, for example, an engagement groove may be used instead of the flange portion 18a.
[0023]
【The invention's effect】
As is clear from the above description, the present invention has the following effects.
(1) In the event of an emergency such as a fire or an earthquake, the wind window equipped with the wind window angle regulating device having the regulating arm can be fully opened immediately. That is, when the electric drive body is in a non-energized state, as soon as the stopper piece is separated from the lock pivot shaft by the spring force of the first spring member, the lock pivot shaft is spring force of the second spring member. As a result, the locked state of the restricting arm is automatically released. Therefore, the other end portion of the restricting arm can be removed from the mounting box, and the wind opening window can be fully opened immediately.
(2) When the electric drive body returns to the normal (energized) state after the lock state of the restriction arm is released, the restriction arm is inserted into the mounting box, and the operation member (the pivot support shaft for locking) ) Is pushed, the restriction arm is automatically locked by a so-called one-touch operation.
(3) Since each member constituting the lock release device is rationally configured, each member can be easily assembled, and each member operates smoothly.
