DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to the drawings.

1 and 2, at the outlet 2 of the air conditioner 1, left and right wind direction plates 3 are formed by a plurality of vertical plates, and upper and lower wind direction plates 4 are further formed by a plurality of horizontal plates. .

The left and right wind direction plates 3 are supported at one point above and below, and are connected at a predetermined position at the rear by a connecting rod 5, which is connected to a left and right wind direction plate driving device 7. Further, the upper and lower wind direction plates 4 are connected by an upper and lower connecting portion 6, and are connected to an upper and lower wind direction plate driving device 9 via a support shaft 8 that supports one of the upper and lower wind direction plates 4.

Furthermore, each of the left and right wind direction plates 3 and the upper and lower wind direction plates 4 has an upper and lower manual knob 10 for manual operation.
0 and left and right manual knobs 101 are respectively provided.

[0014] In the gear transmission 10 to which the left and right wind direction plate driving device 7 and the vertical wind direction plate driving device 9 are attached, for example, when a DC voltage is applied in the positive direction, the first rotating part 11 rotates in a predetermined direction. When the voltage is applied in the opposite direction, the second rotating portion 12 rotates in the predetermined direction.

Left and right wind direction plate drive device 7 shown in FIGS. 3 and 4
is a first rotating plate 13 attached to the first rotating part 11,
The guide plate 14, the first motion conversion section 15, and the first motion transmission section 1 fixed by the screws 103 shown in FIG.
6.

The first rotating plate 13 has a pin 17 near the outer periphery of the plane of the first rotating plate 13, and this pin 17 is connected to a pin formed in the first motion converting portion 15. 1
It is inserted into the sliding groove 18 of No. 7. Guide plate 14
has a protrusion 20 that holds the first motion converting section 15 and the first motion transmitting section 16 by means of a guide wall 19 and a nut 21, and by screwing the nut 21, the first motion converting section 15 and the first motion transmitting section 16 are held. 15 and the first motion transmitting section 16.

[0017] The first motion converting section 15 has the sliding groove 18
and a protrusion 22 that holds the first motion transmitting part 16, a groove 30 through which the protrusion 20 passes, and a joint part 31 with the first motion transmitting part 16. A nut 23 is screwed into the tip via a washer 23 to hold the first motion transmitting portion 16 and to provide a predetermined frictional resistance.

The first motion transmitting portion 16 includes an arm 25 formed to eliminate distortion during formation, a sliding arm 26 that slides on the guide wall 19, and a sliding arm 26 formed at the tip of the connecting rod 5. An insertion section 28 inserted into the transmission section 27, a groove 29 through which the projections 20 and 22 pass, and the first motion conversion section 1
5, and has a joint 32 with the projections 20 and 2.
It is held by nuts 21 and 22 screwed into the tips of the two.

The first rotating plate 13, the guide plate 14, the first motion converting section 15, and the first motion transmitting section 16 are molded from synthetic resin, and the first motion converting section 1
The frictional resistance of the joints 31 and 32 between the first motion transmitting section 16 and the first motion transmitting section 16 is small enough to transmit the motion.

As a result, the first rotating section 13 rotates from the position shown in FIG. 3 to the position shown in FIG. By moving within the sliding groove 18 from the position shown in FIG. 3 to the position shown in FIG. 5, the first motion conversion section 15 slides in the right direction.

In this case, the first motion converting section 15 and the first motion transmitting section 16 move simultaneously due to the frictional resistance of the joint sections 31 and 32, thereby causing the connecting rod 5 to move linearly in the right direction. The left and right wind direction plates 3 change direction from the right direction shown in FIG. 3 to the left direction shown in FIG. 5.

Further, in FIG. 6, when the first rotary plate 13 is stopped or the pin 17 is in the position A, the left and right wind direction plates 3 are moved in the direction C in the figure by the manual knob 101. Since the first motion transmitting section 16 has a clutch action that allows it to be moved with a small force against the frictional resistance of the joints 31 and 32 with the first motion converting section 15, the wind direction plate 3 can be moved manually. However, at this time, the second rotating plate 1
No excessive force is applied to 3.

After this, when the pin 17 rotates due to the rotation of the first rotating plate 13, a force in the direction C acts on the first motion transmitting section 15, but the first motion transmitting section 16 has already been C
Since it is moving to the maximum in the direction, the first motion transmitting section 16
The position does not move, and the first motion conversion unit 15 moves in the direction C from point A to point B against frictional resistance.

After reaching point B, the first motion transmitting section 16 moves to point D.
Since it is movable in the direction, it moves together with the first motion conversion section 15.

Further, FIG. 7 shows an example opposite to the case of FIG. 6.

In this case, the pin 17 is at point B, and the left and right wind direction plates 3 are oriented to the left. Manual knob 1
01, the first motion transmitting part 16 moves in the D direction against the frictional resistance of the joint parts 31 and 32. If pin 17 is rotating, pin 1
The first motion converting section 15 moves in the D direction due to the rotation of 7, but since the first motion transmitting section 16 has already moved to the limit in the D direction, the position of the first motion transmitting section 16 is maintained. The first motion conversion section 15 moves in the D direction against frictional resistance.

After the first motion converting section 15 reaches point A, it moves in the C direction, so the first motion transmitting section 16 moves in the C direction together with the first motion converting section 15. be.

The clutch action caused by the frictional resistance of the joints 31 and 32 between the first motion conversion section 15 and the first motion transmission section 16 prevents a reverse load of more than a predetermined value from being applied to the drive source. be.

As described above, the first motion transmitting section 16 is
When an external force is applied to the wind direction plate 3, independent sliding is possible, and when the external force is removed, the wind direction plate 3 interlocks with the first motion conversion section 15.

As shown in FIGS. 2, 8 and 9, the vertical wind direction plate driving device 9 includes a second rotary plate 40 attached to the second rotating part 12, a second motion converting part 41, a second The movement transmitting part 42 is composed of a joint 43 into which a drive rod 44 that fits into the drive shaft 8 supporting one of the upper and lower wind direction plates 4 is inserted.

A pin 45 is provided protruding from the outside of the circular plane portion of the second rotating plate 40, and this pin 45 is inserted into a sliding groove 46 formed in the second motion converting portion 41. Ru. The second motion converting section 41 and the second motion transmitting section 42 have holes 41a and 42a forming fulcrums that are penetrated by a threaded section 48 of a bolt 47 extending from inside the gear transmission 10, and a washer 49, It is screwed with a nut 51 via a spring 50.

[0032] As a result, the second motion converting section 41 and the second motion transmitting section 42 are connected to the joint sections 41b and 42b with a predetermined frictional resistance. Since the second motion converting section 41 and the second motion transmitting section 42 are made of resin, this frictional resistance is large enough to enable them to interlock, and even when a small external force is applied, the frictional resistance The condition will be canceled.

A hole 42c is formed at the tip of the second motion transmitting portion 42, into which a connecting portion 43b of the joint 43 is inserted.

With this configuration, when the second rotating plate 40 rotates in a predetermined direction, the pin 45 inserted into the sliding groove 46 formed in the second motion converting section 41 rotates, and the second motion converting section 41 rotates. The portion 41 comes to swing at a predetermined angle.

The second motion transmitting section 42 , which is connected to the second motion converting section 41 with a predetermined frictional resistance, moves in conjunction with the swinging of the second motion converting section 41 . The drive rod 44 will be swung through the attached joint 43.

As a result, the drive shafts 8 of the upper and lower wind direction plates 4 connected to the drive rod rotate, and the upper and lower wind direction plates 4 swing up and down.

In FIGS. 10 to 13, the second motion conversion section 41 and the second motion transmission section 42 normally swing from the position indicated by AA' to the position indicated by BB'. At the position AA', the upper and lower wind direction plates 4 are at their most downward position, and at the position BB' they are at their most upward position.

When the upper and lower wind direction plates 4 are moved from their current positions using the upper and lower manual knobs 100, for example, when the upper and lower wind direction plates 4 are facing downward (FIG. 10), the manual knob 100
When the wind direction plate 4 is turned upward, a force is applied to the second motion transmission section 42 via the support shaft 8 and the drive rod 44,
The second motion transmitting part 42 moves to position B' against the frictional resistance of the joint parts 41b and 42b (FIG. 12). Since the force applied to the second motion transmission section 42 by the manual knob 100 can easily resist frictional resistance, the reverse load applied to the second motion conversion section 41 is extremely small.

When the second rotating plate 40 is rotating, the second motion converting section 41 moves from the position A to the position B, but the second motion transmitting section 42 moves from the position B' Since the second motion conversion section 41 is held at the position of the joint section 41
b, 42b, and after the second motion converting section 41 reaches the position B, the second motion transmitting section 42 starts moving together with the second motion converting section 41. It is.

On the other hand, when the upper and lower wind direction plates 4 are in the upward position (FIG. 11), and when the upper and lower wind direction plates 4 are turned downward with the manual knob 100, the second motion transmission section 42 It moves to position A' against frictional resistance and is held at position A' until the second motion converting section 41 reaches position A.

As described above, when an external force is applied to the second motion transmitting section 42 in addition to the movement of the second motion converting section 41, the second motion transmitting section 42 swings independently. and when the external force is removed, the second motion converter 41
It is linked to

[0042] As a result, when a positive DC voltage is applied to the gear transmission 10, the first rotary plate 13 rotates, the left and right wind direction plates 3 swing left and right, and the voltage is applied in the opposite direction. When the second rotary plate 40 rotates, the upper and lower wind direction plates 4 swing up and down.

Furthermore, by periodically varying the direction of application of the DC voltage in the forward and reverse directions, it is possible to drive and control the vertical and horizontal wind direction plates.

[0044]

As explained above, according to the inventions of claims 1 and 2, the control of the upper and lower or left and right wind direction plates can be performed automatically, and the control of the wind direction plates can be performed automatically by installing a clutch mechanism. Manual control is possible, transition from a manually controlled position to an automatic control state is easy, and the clutch mechanism has a simplified configuration.
