A dynamic operation is performed.

In the above embodiment, the embodiment of the operating portion 8 including the handle 13 having an inverted L-shaped cross section is shown, but other operating portions may be applied. Next, the operation of the embodiment will be described.

A rotary shaft 7b provided on the movable blade 7 is pivotally attached to a bearing portion 6a provided on the fixed blade 6 to rotate . At the time of rotation, the arm 7c moves into the recess 10 of the interlocking rod 9.
, And the movable blades 7 ... Are rotated simultaneously by the operating portion 8 at the opening between the fixed blades 6.

The inner peripheral surface of the bearing portion 6a is formed with irregularities so that the rotation of the bearing portion 6a due to rusting or the like does not occur.
The fixed blade 6 is made of an elastic material at the end of the movable blade 7.
Since the contact member 7d for contacting the fixed blade 6 is provided, the movable blade 7 cushions the fixed blade 6. In addition, this
Even if the contact member 7d is provided on the rising portion 6d side of the fixed blade 6, it is the same.
The same effect can be obtained.

The operating portion 8 is provided with a rotary operation of the movable blade 7.
By providing the locking portion B for restraining its movement to a position corresponding to the lower two positions, rotated and fixed operation of the movable blade 7 is smooth. That is, since the lock rods 12 and 12 are engaged with the engagement holes 15a and 15a, respectively, when the louver is opened or closed, the lock operation can be easily and surely performed only by operating the handle 13.

The lock rods 12 and 12 are engaging portions 1 respectively.
Since the elastic members 14 and 14 are pressed to the 5 and 15 sides, both open and closed states of the louver are stable, and the lock rods 12 and 12 are interlocked with the handle 13 and the lock rods 12 and 12 are elastic members 1.
Since it moves to the side opposite to the engaging portions 15 and 15 side against 4 and 14, the movement of the interlocking rod 9, that is, the rotation of the movable blades 7 ... Is easy.

Next, the effect of the embodiment will be described. Since the movable blades 7 are merely in contact with the upper and lower contact portions 10a and 10b of the recess 10 formed in the interlocking rod 9 that constitutes the operation portion 8, the configuration is extremely simple. Therefore, when the operation portion 8 is attached or detached, it is not necessary to consider the separation from the movable blade 7.

Moreover, since the movement of the movable blade 7 is locked when the louver is "open" and "closed", the posture can be reliably maintained. Further, since the inner peripheral surface of the bearing portion 6a is formed with irregularities, even if the bearing portion 6a or the rotary shaft 7b is rusted, the rust is collected in the concave portion, which hinders the rotation. The movable blades 7 can be smoothly rotated for a long period of time.

The abutment member 7d of the movable blade 7 .. end Gala
Since the collision with the fixed blades 6 at the bottom is softened when the lid is closed, both blades 6 and 7 are less damaged and the collision noise is less likely to occur. Further, since the contact member spatially blocks between the end of the movable blade 7 and the fixed blade 6, there is also a heat insulating effect.

[0036] In the operation unit 8 only to be locked in the moved position of the upper and lower, because it is possible to lock the movable blade 7 to the open position and the closed position of the louver, the rotation of the operability is good movable blade 7 operates and The lock can be performed efficiently. By depressing the handle 13 of the lock portion B, the interlocking rod 9 can be moved up and down, so that the movable blade 7 can be easily rotated , and since the structure is simple, the manufacturing cost is low and the breakdown is small. There is an effect.

As described above, the handle 13 is used in this embodiment.
The movable blade 7 can be easily rotated only by lowering the lever to unlock it and moving the operating portion 8 up and down. Further, since the lock rod 12 is pressed toward the engaging portion 15 side by the elastic member 14, the lock rod 12
The movable blade 7 can be easily operated / not operated by operating the handle.
・ ・Rotation is light.

In the embodiment, the case where the louver is in only two states , open and closed, is illustrated, but one or more open states in the intermediate stage may be set.

Further, in the above embodiment, the movable blades are moved up and down.
Although an example in which the movable blade is rotated is shown, it may be applied to a structure in which the rotary shaft of the movable blade is provided in the up-down direction so as to rotate left and right.

[0040]

Since the present invention is constructed as described above, it has the following effects. 1. According to the invention described in claim 1, since the movable blade is simply brought into contact with the concave portion formed in the interlocking rod that constitutes the operation portion, the configuration is extremely simple. Therefore, it is not necessary to consider separation from the movable blade when mounting / removing the operation portion. Moreover, the movable blade is loose
Since the movement is locked at the “open” position and the “closed” position of, the posture can be reliably maintained.

2. According to the invention as set forth in claim 2, in addition to the effect of the invention as set forth in claim 1, since the inner peripheral surface of the bearing portion is formed with irregularities, the bearing portion or the rotary shaft will rust temporarily.
