Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a register that air-conditions the interior of an automobile or the like.

[Conventional technology]

As shown in FIGS. 2 and 3, the conventional register includes a plurality of vertical blades 3 whose upper and lower ends are rotatably supported by a bezel 2 attached to the front surface of a cylindrical retainer 1. The wind direction is controlled by rotating the horizontal blades 4 whose left and right ends are pivoted within a predetermined angle range by appropriate means, and which protrude to the front from an opening provided in the bezel 2. By rotating the knob 6 with your fingers, the sector 7 provided integrally with the knob 6 and the pivot end of the damper 5 whose center portions of both edges are rotatably supported on the side wall of the retainer 1. Via the fixed pinion 8,
A duct (not shown) connected to the rear of the retainer 1 and giving the damper 5 a desired inclination angle.
It controls the volume of air that is blown through.

[Problem that the invention attempts to solve]

In a conventional resistor with such a configuration, the damper 5 is located approximately in the center of the duct, so even when the damper is not activated, that is, when the damper is in a horizontal position, the ventilation resistance is large and the passing wind is disturbed. The problem was that wind noise was generated. Additionally, the internal damper was visible from the front of the register through the gap between the blades, which caused an undesirable design.

[Means for solving problems]

The present invention aims to solve the problems in the prior art, and includes forming an air outlet in the front part of a retainer fitted into the front surface of a duct, and an air outlet formed by the duct and/or the retainer. In the air conditioning register, the damper is provided with a damper rotatably supported at both ends on the side wall of the retainer so as to cross an air passage and change the cross-sectional area of the passage. The present invention provides a damper mounting structure characterized in that a recess is provided in the damper section to accommodate the damper in an inoperative position.

〔Example〕

The present invention will be explained in more detail on the basis of preferred embodiments shown in the drawings.

FIG. 1 shows a side sectional view of the resistor according to the present invention, and its basic structure is the same as that of the prior art shown in FIGS. 2 and 3, except for the mounting structure of the damper 5. . The same reference numerals have therefore been used for corresponding parts.

The retainer 1 has a step portion 1a whose bottom wall protrudes outward, has a length corresponding to the width of the damper 5, and continues to its rear open end. The communicating ducts 10 are airtightly connected via a sealing elastic member 11. Stepped portion 10a provided at the front end of the duct 10
and the stepped portion 1a of the retainer 1, the recess 1
2 is formed at the bottom of the retainer 1. One end 5a of the damper 5 is rotatably supported by a pin 13 at the lower part of the side wall of the retainer 1, which corresponds to the front end of the stepped portion 1a.

A sealing elastic member 14 is adhered to the other end 5b of the damper 5, and when the damper 5 is rotated clockwise to the maximum around the pin 13 in the figure, the end 5b touches the top of the retainer 1. It is configured so that it can come into contact with the wall and completely block the air passage. For this reason, the top wall of the retainer is provided with a stepped portion 1b that crosses the top wall to make more complete contact with the sealing elastic member 14.

In such a configuration, when in the inoperative position,
As shown by the imaginary line in FIG.
It lies completely housed within the retainer 2 and provides no resistance to the air passing through the retainer 1. Therefore, the conventional problem of wind noise is eliminated. Furthermore, in this stored state, the damper 5 cannot be seen from the front of the register, which solves the aesthetic problem.

FIG. 4 shows another embodiment of the invention, according to which the recess 12 is provided inside the retainer 1 itself and the duct (not shown) has a step 10a as shown in FIG. There is no need to provide one.

Although it is desirable that the depth of the recess is such that it completely hides the damper, there is almost no practical problem even if the damper is exposed to some extent.

Further, in the above description, an example was described in which the recess was provided on the bottom wall side, which is the part of the air passage where the wind speed is slowest, but it is also possible to provide the recess on the top wall or side wall.

[Effect of idea]

According to the present invention, when the damper is in the inoperative position, it is substantially housed in the recess provided in the retainer, so it does not create resistance to the air passing through it, thereby causing noise and aesthetic problems. can be solved.
