Description

[Detailed Description of the Invention] <Industrial Field of Application> This invention relates to a register that is installed in an air supply duct or the like of an automobile and allows outside air to flow into the interior of the automobile.

<Prior art> As shown in FIGS. 7 and 8, the conventional resistor 1 is made of synthetic resin such as ABS or PP, and the flange portion 2a located on the opposite side of the opening portion 3 is connected to the air supply duct 10. A substantially square cylindrical register body 2 fixed with a screw 9, and an opening 3 of this register body 2.
The damper 4 was provided with a generally flat plate-like damper 4 having both ends of a shaft portion 4a pivotally attached to mounting holes 2b, 2b on the periphery. The damper 4 has gripping portions 4b each protruding from the shaft portion 4a to the outside of the register body 2 in the radial direction.
and a blade portion 4c protruding into the register main body 2, and by operating the grip portion 4b, the shaft portion 4
The blade portion 4c was configured to rotate around point a to open and close the opening 3 of the register body 2.

In the conventional register 1, the opening 3 of the register body 2 is opened by operating the grip part 4b of the damper 4.
The blade portion 4c of the damper 4 is biased by a torsion coil spring 5 so that the position of the damper 4 is maintained when the damper 4 is closed and fully opened.

Specifically describing the arrangement state of the torsion coil spring 5, one end of the torsion coil spring 5 is rotatably fixed with a screw 6 at a diagonal position of the mounting hole 2b on the side surface of the register main body 2, and the torsion coil spring 5 is The other end was rotatably locked to a screw 7 that passed through the side surface of the register body 2 and was screwed onto the blade portion 4c of the damper 4. Further, a substantially 1/4 arc-shaped sliding hole 2c is formed on the side surface of the register body 2 so that the screw 7 can pass therethrough when operating the damper 4, and a sealing member 8 is disposed in this sliding hole 2c. It had been.

Note that 11 and 12 are the blade portions 4 of the damper 4, respectively.
This is a sealing member that is adhered to the shaft portion 4a and the vicinity of the shaft portion 4a, and seals the periphery of the opening 3 when the opening 3 of the register body 2 is closed.

<Problem to be solved by the invention> Therefore, in the conventional register 1, the damper 4 in each of the closed and fully open positions of the register body opening 3 is biased by the torsion coil spring 5. The torsion coil spring 5 and the screw 6 for attaching the spring 5 are configured so as to be regulated and maintained in that position.
7 is required, the number of parts is large, it takes time to assemble, and the assembly man-hours and costs are increased.

This invention solves the above problem, and allows the damper to be maintained in each position when the opening of the register body is closed and when it is fully opened, without using a torsion coil spring, reducing the number of parts, and making it easier to assemble. It is an object of the present invention to provide a register that can reduce the number of man-hours and costs, and can also be lightweight.

<Means for Solving the Problems> In the register according to this invention, a damper disposed in the opening of the register body made of synthetic resin has a shaft portion pivotally attached to the periphery of the opening, and a damper disposed in the opening of the register body made of synthetic resin. A register that is equipped with a grip part that projects outside the register body and a blade part that projects into the register body, and that opens and closes the opening by operating the grip part and rotating the blade part around the shaft part. An elastic piece that can be elastically deformed in a direction away from the grip part is integrally provided on at least one side of the end surface of the grip part along the axial direction of the shaft, and the elastic piece protrudes integrally from the register body. The above-mentioned problem can be solved by forming a bulge that contacts the end surface of the grip at a position approximately halfway between when the opening is closed and fully opened when the grip is operated, and deforms the elastic piece in a spring-elastic manner. This is to solve the problem.

<Operations and effects of the invention> In the register according to this invention, when the damper is operated, the damper touches its grip part to the bulge part of the elastic piece at a position approximately halfway between when the opening of the register body is closed and when it is fully opened. When brought into contact with each other, the elastic piece is deformed in a spring-elastic manner. Therefore, when the damper closes or fully opens the opening, it deforms the elastic piece elastically, and then releases the deformation to close or fully open the opening. When the damper is closed or fully opened, the damper is held in a so-called snap position by an elastic piece.

Therefore, in the resistor according to this invention, the damper at each position when the register body opening is closed and fully opened is formed by an elastic piece that integrally projects from the register body, without using a torsion coil spring. Since the conventional torsion coil spring mounting screws and the like are not required, the number of parts can be reduced, the number of assembly steps and costs can be reduced, and the weight can be reduced.

<Example> An example of this invention will be described below based on the drawings.

As shown in FIGS. 1 to 3, the resistor 21 of the embodiment is composed of a resistor body 22 and a damper 24, both of which are made of synthetic resin such as ABS or PP, as in the prior art.

The register main body 22 has a substantially rectangular cylindrical shape as in the conventional case, and has a substantially rectangular opening 23 and a substantially rectangular opening 23.
A flange part 22a is fixed to the air supply duct 10 with screws 9 at the end opposite to 3, and mounting holes 22b, 22b are provided at the lower part of the periphery of the opening 23 to pivotally attach both ends of the shaft part 24a of the damper 24. ing.

The register main body 22 has two elastic pieces 25, 25 on its lower outer surface that are perpendicular to the shaft portion 24a of the damper 24 which is pivotally attached to the mounting holes 22b, 22b and protrude from the lower peripheral edge of the opening 23. is integrally formed when the register body 22 is molded.

These elastic pieces 25, 25 are connected to the mounting holes 22b, 2
When the damper 24 is assembled to the register main body 22 via the damper 24b, the damper 24 is formed at the side of both end surfaces along the axial direction of the shaft portion 24a in the grip portion 24b of the damper 24 at a position that does not contact the both end surfaces thereof, and ,
Each is formed into a shape that can be elastically deformed in a direction away from both end surfaces along the axial direction of the shaft portion 24a.

In addition, bulges 25a are formed at the tips of these elastic pieces 25, 25 to face each other and gently protrude. It comes into contact with the grip part 24b of the damper 24 at a substantially intermediate position excluding the time,
The elastic pieces 25, 25 are formed to be elastically deformed and separated from each other.

As mentioned above, the damper 24 is connected to the register body 2.
It is provided with a shaft portion 24a whose both ends are pivotally attached to the two mounting holes 22b, 22b, and a grip portion 24b and a blade portion 24c each protruding from the shaft portion 24a in the radial direction. These gripping portions 24b and blade portions 2
4c means that when the damper 24 is assembled to the register body 22 via the shaft part 24a, the grip part 24b protrudes outside the register body 22, and the blade part 24c
It protrudes into the register body 22, rotates around the shaft 24a when the grip 24b is operated, and opens the opening 23.
It is formed in a shape that allows it to be closed.

Note that when the damper 24 is assembled to the register main body 22, the outer surface of the blade portion 24c of the damper 24, and the inner surface of the shaft portion 24a and the grip portion 24b,
As in the past, when the opening 23 is closed, sealing members 11 and 12 made of rubber foam sheets or the like are adhered to seal the periphery of the opening 23 (see 2 in FIG. 1).
(See dot-dashed line).

Further, 24d indicates that when the opening 23 is fully opened,
This is a protrusion that comes into contact with the inner peripheral surface of the register body 22.

To describe how to assemble this register 21, simply insert the damper 24 into the opening 23 of the register main body 22 from the blade part 24c, and insert both ends of the shaft part 24a of the damper 24 into the mounting holes 22b, 22b of the register main body 22. It can be assembled by simply pivoting the parts. In addition, when attaching this resistor 21 to the air supply duct 10, it is possible to attach the register body 22 to the air supply duct 10 with the screws 9 after assembling the register 21 as described above, or by fixing the register body 22 with the screws 9 to the air supply duct 10 in advance. Then, the damper 24 may be assembled to the register body 22 as described above.

Describing how this register 21 is used, for example, when the opening 23 is closed as shown in FIGS. 1 to 3, it is fully opened as shown in FIG. As shown in FIG. 1, the grip portion 24b of the damper 24 is
If it is rotated 90 degrees counterclockwise, the blade portion 24c will also rotate around the shaft portion 24a, and the opening portion 23 will be fully opened. At this time, in the intermediate position from the closed state to the fully open state, as shown in FIGS.
5a, 25a abut on the grip part 24b, and the elastic piece 2
5 and 25 are each elastically deformed and are fully opened, the gripping portion 24b touches the bulging portions 25a and 25.
Since it is removed from contact with 25a, its fully open state is maintained, as in a so-called snap fastening.

Furthermore, even when changing from the fully open state to the closed state, the closed state is maintained as in the case of snapping, as described above.

Therefore, in the register 21 of the embodiment, the damper 24 in each position when the opening 23 of the register main body 22 is closed and fully opened can be moved to the register main body 2 without using the conventional torsion coil spring.
It can be maintained by the elastic pieces 25, 25 that integrally protrude from 2, and there is no need for conventional torsion coil spring mounting screws, etc., reducing the number of parts, reducing assembly man-hours and costs, and reducing weight. It is possible to aim for

Furthermore, if the shape of the elastic piece 25 is taken into account to obtain a predetermined spring elastic force, it is possible to obtain the same operational feeling as the register 1 using a conventional torsion coil spring.

In addition, in the embodiment, the elastic piece 25 is attached to the grip part 24b.
Although we have shown two locations on both sides of the
It may be provided on either side. Incidentally, when the grip portions 24b are provided on both sides as in the embodiment, there is an effect that moderation can be easily achieved.

In addition, in the embodiment, the bulging portion 25a of the elastic piece 25
Although the bulge portion 25a is formed integrally with the elastic piece 25, if it is not possible to form the bulge 25a integrally with the elastic piece 25, of course, the bulge portion 25a can be formed separately on the elastic piece 25 using adhesive or welding. may be fixed.
