DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS.
A preferred embodiment of the automotive register according to the present invention will be described. FIG. 1 shows a main configuration of a register according to this embodiment. As described above, the register 10 is installed around a dashboard, for example, and blows air into the room as appropriate. The register 10 is connected to a ventilation pipe of a ventilator (not shown), and sends out the wind sent from the ventilator.

In FIG. 1, a register 10 has a hollow housing-like retainer 11 which constitutes an air passage for circulating the wind sent from a ventilator, and is turned around a horizontal support shaft 12a at an inlet 11a of the retainer 11. A single damper 12 supported movably (vertically) and an operation dial 13 supported rotatably (horizontally) around a vertical support shaft 13a at an outlet 11b of the retainer 11 are provided. ing. The outlet 14b of the retainer 11 is provided with a barrel 14 for changing the direction of the wind sent from the outlet 11b.

The operation dial 13 and the damper 12 are connected via a link mechanism 15. The link mechanism 15
The damper 12 and the operation dial 13 are connected so that the operation direction (arrow V) and the operation direction of the operation dial 13 (arrow H) are orthogonal to each other.
That is, the link mechanism 15 includes a plurality of link members 16, 1
7 and 18, the operating direction between the operation dial 13 and the damper 12 can be changed from the horizontal direction to the vertical direction by the flexibility of these link members and the clearance of the connecting portion between the link members.

In this example, as shown in FIG. 2, the link member 16 is formed in a crank shape and is rotatable (horizontally) around a pin 19 provided on the retainer 11. Then, the pin 13b of the operation dial 13 is loosely fitted into the elongated hole 16a provided at one end thereof, and the operation dial 13
And pin connection. The link member 16 is also pin-connected to the link member 17 by fitting a pin 17a of the link member 17 into a hole 16b provided on the other end side. In this case, the tip of the pin 17a is formed in a tapered tapered shape, and the hole 1 is maintained while being connected to the link member 17.
6b can be fitted with an appropriate inclination. Further, the link member 18 is fixed to the damper 12 by the horizontal support shaft 12a, and the pin 17b of the link member 17 is fitted into the hole 18a, so that the link member 17 is pin-connected.

As described above, the link members 16, 17, and 18 constituting the link mechanism 15 are formed of a synthetic resin material and have appropriate elasticity and flexibility. Therefore,
Each link member can be appropriately bent and deformed with respect to the load during the link operation, and can be returned from the deformation. In particular, the connection between the link member 16 and the link member 17 ensures proper link connection while being slightly distorted.

In the above configuration, when the operation dial 13 is turned, the link member 16 is turned in the horizontal direction, whereby the link member 17 is turned in the vertical direction while the link member 17 is inclined. In this way, the operating direction of the operation dial 13 and the damper 12 is changed by 90 °, and the operation of the operation dial 13 can reliably open and close the inflow port 11a of the retainer 11.

In the link operation of the damper opening / closing mechanism, the operating direction of the operation dial 13 and the damper 12 is changed by utilizing the flexibility of each of the link members 16, 17, and 18 and the clearance of the connecting portion between the link members. However, smooth and proper operation can be ensured. In this case, the air passage can be opened and closed by one damper 12 irrespective of the setting position of the operation dial 13, and since the single damper 12 is used, the sealing performance is excellent, and the operation sound and operation feeling are improved. improves. Furthermore, since the mechanism has a simple configuration without using a complicated gear mechanism or the like, manufacturing and product costs are low, and design is easy.

[0017]

As explained above, according to the present invention,
By devising the material characteristics, shape, and the like of the components of the link mechanism in this type of register, it is possible to exhibit a smooth operation and proper functions while having a simple configuration. Also,
Since it has a compact configuration, it has excellent mountability and can solve problems such as design and space.
