Next, the first raised portion 11 in FIG.
The shapes of a and 11b will be described with reference to FIG. FIG. 2 is a sectional view taken along the line AA in FIG. 1, and as shown in FIG. 2, the first raised portions 11a and 11b
Is integrated with the wall of the duct 1 and the first rope 12
Is sandwiched between. Also, the second bulging portion 2 in FIG.
The shapes of 3a and 23b are the same as those shown in FIG.

Next, the configuration and operation of the third shaft 19 and the fourth shaft 21 will be described with reference to FIG. Here, FIG. 3 is a perspective view schematically showing a relative positional relationship among the third shaft 19, the fourth shaft 21, the second intermediate shaft 25, the third intermediate shaft 26, and the second film damper 27. The following description is also applied to the configuration and operation of the first shaft 7 and the second shaft 9.

As can be seen from FIG. 3, the third shaft 1
9 is a gear 33 having a circular saw-shaped cross section.
It has become. Further, a stopper 34 is attached to the third rope winding pulley 20. The stopper fulcrum 340, which is the fulcrum of the movement of the stopper 34, is connected to the third rope winding pulley 20 by a spring.
The tip of 4 is in contact with the gear 33. Here, since the cross-sectional shape of the third shaft 19 is difficult to understand in FIG. 3, refer to FIG. 4 which shows a partial cross-sectional view taken along the line BB of FIG.

As can be seen from FIG. 4, the third shaft 19
Is hollow, and the motor 101
And a speed reducer 102 for reducing the output from the motor 101. The motor 101 and the speed reducer 102
And the side of the speed reducer 102 is the third
It is in close contact with the inner side surface of the shaft 19. The cross section is D
The motor output shaft 41 is connected to a motor mounting boss (not shown) which is a part of the duct 1 (not shown), and the motor output shaft 41 rotates to rotate the motor 1.
01 itself rotates, and the third shaft 19 also rotates. The power cord 43 (not shown in FIG. 3) has one end connected to the motor 101 and the other end connected to a control device (not shown).

Referring back to FIG. 3, the third shaft 1
If 9 rotates counterclockwise when viewed from the front of the drawing, the second
The film damper 27 is wound around the third shaft 19. Since the gear 33 is integral with the third shaft 19, the gear 33 also rotates counterclockwise. By the way, as can be seen from FIG. 3, when the gear 33 rotates counterclockwise, the third rope winding pulley 20 does not rotate no matter how much the gear 33 rotates because the gear 33 and the stopper 34 are not caught. That is, the torque of the third shaft 19 is not transmitted to the fourth shaft 21 via the second rope 24. That is, only the force transmitted through the second film damper 27 rotates the fourth shaft 21.

Here, it is assumed that the second film damper 27 is loose. At this time, even if the third shaft 19 rotates counterclockwise, the fourth shaft 21 does not rotate while the second film damper 27 is loose. The fourth shaft 21 rotates only after the second film damper 27 is stretched. That is, even if the second film damper 27 is loosened, the third shaft 19 can be easily loosened by rotating counterclockwise.

Next, the case where the third shaft 19 rotates clockwise will be described. When the third shaft 19 rotates clockwise, the gear 33 also rotates clockwise. At this time, the gear 33 and the stopper 34 are engaged with each other, and the gear 33 presses the stopper 34, so that the third
The rope winding pulley 20 also rotates clockwise.

When the third rope winding pulley 20 rotates clockwise, the second rope 24 is wound. When the second rope 24 is wound around the third rope winding pulley 20, the fourth shaft 21 also rotates clockwise. 4th shaft 2
When 1 rotates clockwise, the fourth shaft 21 winds up the second film damper 27.

As described above, when the third shaft 19 rotates clockwise, the third shaft 19 sends out the second film damper 27. At this time, the fourth shaft 19 is simultaneously rotated.
Since the shaft 21 also rotates clockwise, the second film damper 27 is wound around the fourth shaft 21 without slack.

In summary, when the third shaft 19 rotates counterclockwise, even if the second film damper 27 is loosened, the fourth shaft 21 rotates until the second film damper 27 is stretched. No loosening can be easily done. When the third shaft 19 rotates clockwise, the third rope take-up pulley 20 also rotates clockwise to rotate the fourth shaft 21 clockwise. 21 winds up the second film damper 27 and the third shaft 19
Has the same effect as rotating counterclockwise.

When the third shaft 19 and the fourth shaft 21 are configured and operated as described above, they can be easily assembled at the time of initial assembly. Here, the operation at the time of the initial assembly will be described with reference to FIG. 5 (the second rope 24 is indicated by a dashed line).

First, before assembling, the length of the second rope 24 is made longer than the length of the second film damper 27.
Then, one end of the second film damper 27 is connected to the third shaft 1.
9 and the other end is fixed to the fourth shaft 21. Then, the fourth shaft 21 is rotated clockwise to lightly wind the second film damper 27. Then the second rope 24
Is fixed to the third rope take-up pulley 20 and the other end is fixed to the fourth rope take-up pulley 22, and the second rope 24 is slightly wound (see FIG. 5 (a)).

Further, the third shaft 19 is rotated counterclockwise to wind up the second film damper 27, so that the second film damper 27 is stretched. However, even if the second film damper 27 is stretched, the second rope 24
Has not yet been wound (see FIG. 5B).

When the second film damper 27 is further wound, the fourth shaft 21 rotates counterclockwise to wind up the second rope 24. Then, the second rope 24 is also put in a stretched state. (See FIG. 5 (c).)
Although the operation of the shaft 19, the fourth shaft 21, the second film damper 27, and the second rope 24 at the time of the initial assembly has been described, the first shaft 7, the second shaft 9, the first film damper 14, and the first The same applies to the operation of one rope 12 at the time of initial assembly.

As described in detail above, in the first embodiment, the gear and the rope take-up pulley are provided at the end of the shaft, so that the film damper can be always in a stretched state. Noise can be eliminated. Also, at the time of initial assembly, it can be easily assembled.

Further, by incorporating the motor 101 in the first shaft 7 and the third shaft 19,
It is possible to save the space of the portion where the 01 is mounted outside the duct 1.

Further, since the position of the film damper is detected by the photo interrupter, the film damper can be stopped accurately. In the first embodiment, one shaft is the first shaft 7 and the third shaft 19, and the other shaft is the second shaft 9 and the fourth shaft 21. The driving means includes a motor 101 and a speed reducer 102, the first transmission means is a motor output shaft 41, and the one-way clutch is a gear 33. The second transmission means includes a first rope winding pulley 8, a second rope winding pulley 10, a first rope 12, a third rope winding pulley 20, a fourth rope winding pulley 22, a second rope 24,
And a stopper 34.

Next, a second embodiment of the present invention will be described with reference to FIGS.
It will be described based on. First, a second embodiment will be described with reference to FIG. FIG. 6 is a cross-sectional view of FIG. The arm 35 and the claw 36 in FIG.
It is united with. By the way, the first pulley 37 is
As shown in the figure, arms 35 and claws 36 are alternately provided at 90 ° intervals in the upper part of the drawing.

When the first shaft 7 is rotated counterclockwise in FIG. 6, the pinion gear 38 meshes with the internal gear 39 provided on the inner side surface of the first shaft 7, and the pinion gear 38 rotates counterclockwise. Attempts to revolve counterclockwise while rotating. However, when the pinion gear 38 tries to rotate in a counterclockwise direction, the pinion gear 38 and the claw 36 are firmly engaged this time, and the pinion gear 38 cannot rotate.

The inability of the pinion gear 38 to rotate means that the pinion gear 38 and the internal gear 39 of the first shaft 7 are firmly fixed. Therefore, the rotational force of the first shaft 7 is directly applied to the pinion gear 3.
It is transmitted to 8. Then, with the rotation of the first shaft 7, the pinion gear 38 pushes the claw 36 of the first pulley 37 and the first
The pulley 37 itself also rotates counterclockwise.

Conversely, when the first shaft 7 is rotated clockwise, the internal gear 39 of the first shaft 7 meshes with the pinion gear 38, and the pinion gear 38 revolves clockwise while rotating clockwise. I do.

Here, since the arm 35 has a curved portion different from the claw 36, unlike the case where the first shaft 7 rotates counterclockwise, the pinion gear 38 does not mesh with any portion, and the pinion gear 38 is It keeps spinning forever while sliding on the curved surface. In other words,
The rotational force of the first shaft 7 is not transmitted to the first pulley 37 via the pinion gear 38, so that no matter how much the first shaft 7 rotates clockwise, the first pulley 37 does not rotate.

Returning to FIG. 8, when the first shaft 7 is rotated in the direction in which the first film damper 14 is fed out, the pinion gear 38 and the claw 36 described in FIG. Also rotates in the same direction as the first shaft 7. Then, as the first pulley 37 in FIG. 8 rotates, the second pulley 40 also rotates in the direction of winding the first film damper 14 via the first rope 12.

When the first shaft 7 is rotated in the direction of winding the first film damper 14, the pinion gear 38 described with reference to FIG. It does not rotate, and consequently the first shaft 7 winds up the first film damper 14, whereby the second shaft 9 also rotates.

The first shaft 7 has a hollow content, and a motor 101 and a speed reducer 102 are built in the hollow portion. Further, the motor 101 and the speed reducer 102 are integrally formed, and the outer peripheral side surface of the speed reducer 102 is fixed in contact with the inner peripheral side surface of the first shaft 7. The cross section is D
The motor output shaft 41 is connected to a motor mounting boss (not shown) which is a part of the duct 1 (not shown), and the motor output shaft 41 rotates to rotate the motor 1.
01 itself rotates, and the first shaft 7 also rotates. Also,
The power cord 43 not shown in FIG. 3 has one end connected to the motor 101 and the other end connected to a control device not shown.

A first hole 44 for supporting the first pulley 37 is provided at the tip of the first shaft 7. Here, the first hole 44 and the first pulley 37 are not in close contact with each other, but the first pulley 37 supported by the first hole 44 is rotatable.

The tip of the second pulley 40 has a D-shaped cross section, and the D-shaped portion of the second pulley 40 and the D-shaped portion of the third hole 48 are firmly engaged and fixed.

The fourth hole 49 is also provided in the duct 1. The second cover 50 surrounding the second pulley 40 is inserted into the fourth hole 49, and the second pulley 40 is inserted inside the second cover 50. Second cover 5
The second cap 51 is fitted in the zero. Also the second
The shaft 9 is supported by a shaft mounting boss 52.

The first raised portions 11a and 11b are integral with the wall of the duct 1 as described with reference to FIG.
Rope 12 is sandwiched. The two-dot chain line in the drawing represents the first film damper 14, and the first film damper 14 has an opening 53.

The second embodiment has been described above.
The embodiment is not limited to the air mix damper, but can be applied to an outlet switching damper and other film dampers. In the second embodiment, the second transmitting means is the claw 3
6, a first pulley 37, and a second pulley 40. The one-way clutch includes an arm 35, a pinion gear 38, and an internal gear 39.
