Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a shut damper capable of opening and closing an air passage of a register mounted on an instrument panel of a vehicle, for example.

[Prior Art] A vehicular register also employs a shut damper capable of opening and closing an air passage thereof, so that air can be blown out or stopped in all modes of the register.

11 to 13 show an example of a conventional shut damper 50. As is clear from these drawings, the shut damper 50 mainly includes a damper plate 52 and a seal body 60. A groove 56 is continuously formed on the outer peripheral edge 54 of the damper plate 52. The seal body 60 is made of a material such as rubber and formed in an annular shape corresponding to the outer shape of the damper plate 52. This seal body
The damper plate 52 and the seal body 60 are integrated by fitting the inner peripheral edge portion of the groove 60 into the groove 56 as shown in FIGS. 12 and 13.

The seal body 60 contacts the inner wall surface of the air passage when the air passage of the register is closed by the shut damper 50, whereby the inner wall surface of the air passage and the shut damper 50.
The airtightness between and is maintained.

[Problems to be solved by the device]

When the size of the damper plate 52 in the horizontal direction is large like the shut damper 50 in FIGS. 11 to 13, the size of the seal body 60 in the horizontal direction is naturally large.
For this reason, the portion of the seal body 60 located below the damper plate 52 falls off the groove 56 due to its own weight and vibration as shown by the phantom line in FIG. As a result, the airtightness of the shut damper 50 when the air passage of the register is closed is reduced.

A technical problem of the present invention is to provide a shutoff damper for a register that can prevent the seal body from coming off from the damper plate due to its own weight or vibration even when the size of the damper plate in the left-right direction is large.

[Means for solving the problem]

In order to solve the above problems, the register shut damper of the present invention is configured as follows.

(1) A damper plate is provided in the air passage of the register so that the passage can be opened / closed, and a ring-shaped continuous seal body is fitted into a groove formed in an outer peripheral edge of the damper plate. A register shut damper of the type described above, in which a relief portion having one side of the groove open and a locking projection are provided at substantially the middle portion in the left-right direction at the lower edge portion during the opening / closing operation of the damper plate. And a coupling portion that can be coupled to the locking projection is integrally formed on the seal body at a position corresponding to the relief portion.

(2) A damper plate is provided in the air passage of the register so that the passage can be opened / closed, and a ring-shaped continuous seal body is attached by fitting into a groove formed in an outer peripheral edge of the damper plate. A register shut-damper of the type described above, in which substantially one middle of the groove at the upper and lower edges of the damper plate in the left-right direction is formed with a communicating portion in which one side of the groove is opened and communicated vertically. In addition, the seal body is integrally formed with a vertically continuous coupling portion at a position corresponding to the communication portion.

[Action]

In the configuration (1), in order to assemble the seal body to the damper plate, the inner peripheral portion of the seal body is fitted into the groove formed in the edge portion of the damper plate, and It is only necessary to connect the connecting portion to the locking protrusion through the relief portion of the damper plate. Further, in this assembled state, since the coupling portion and the locking projection are coupled, the seal body is detached from the groove of the lower edge portion and hangs downward during the opening / closing operation of the damper plate. Things are resolved. As a result, even if the size of the damper plate in the left-right direction is large, the airtightness between the air passage of the register and the shut damper is appropriately maintained.

According to the configuration (2), by simply fitting the inner peripheral portion of the seal body into the groove of the damper plate, the coupling portion that is continuous in the vertical direction of the seal body is located in the communication portion of the damper plate, Assembly of the seal body to the damper plate is completed. The connecting portion prevents the seal body from coming off from the groove of the lower edge portion during the opening / closing operation of the damper plate, and the airtightness between the air passage of the register and the shut damper is appropriately maintained. It

〔Example〕

Next, an embodiment of the present invention will be described with reference to FIGS.

First Embodiment First, FIG. 5 shows a schematic sectional view of a vehicle register. In FIG. 5, a plurality of horizontal fins 14 are arranged in parallel in the vertical direction inside the retainer 10 forming the air passage 12 of the register on the air outlet side (right side in the drawing). . A plurality of vertical blades 16 are arranged in parallel along the left-right direction in the air passage 12 on the back side (left side in the drawing) of the horizontal fins 14.
However, in FIG. 5, only one of the vertical blades 16 is shown.

The horizontal fins 14 and the vertical blades 16 are rotatably supported by the retainer 10, and the amount of rotation thereof can be adjusted by operating a knob (not shown). It is well known that the direction of the air blown into the vehicle from the air passage 12 can be changed by this. However, various fins 14 may be fixed to the retainer 10.

In the air passage 12, a shut damper is provided on the upstream side (left side in FIG. 5) of the horizontal fins 14 and the vertical blades 16.
20 are provided. The shut damper 20 is attached to the retainer 10 so that the air passage 12 can be opened and closed. That is, the shut damper 20 is operated to a virtual line state (open state) or a solid line state (closed state) shown in FIG. 5 through a link or the like by operating an opening / closing knob (not shown).

FIG. 1 is an exploded perspective view of the shut damper 20, FIG. 1-a and FIG. 1-b are partially enlarged views of FIG. 1, and FIG. A sectional view taken along line II-II is shown. As is apparent from FIG. 1, the shut damper 20 is formed of a damper plate 22 made of a material such as a synthetic resin and an annular shape made of urethane, felt, rubber or the like corresponding to the outer shape of the damper plate 22. The seal body 40 is mainly configured.

First, the damper plate 22 is formed such that the thickness of the outer peripheral portion thereof is larger than that of the central portion thereof, and the peripheral edge portion 24
A groove 26 is continuously formed in the groove. The inner peripheral portion of the seal body 40 can be fitted into the groove 26. Support shafts 28 are integrally formed on both left and right sides of the damper plate 22, respectively. However, the support shaft located on the left side in FIG. 1 is not shown in the drawing. These support shafts 28 allow the damper plate 22 to be rotatably assembled to the retainer 10 shown in FIG.

As is clear from FIG. 1-a and FIG. 2, an edge portion of the edge portion 24 of the damper plate 22 located on the lower side of the drawing.
24A is a relief portion in which one side of the groove 26 (left side in FIG. 2) is cut off at a constant width in a substantially middle portion in the left-right direction.
It is 25. Further, a locking projection 30 is integrally formed on the damper plate 22 on the same side as the escape portion 25. As shown in FIG. 1-a, the locking projection 30 has a head portion 30a which extends laterally. The edge portion 24A on the lower side of the drawing in which the escape portion 25 is formed is the edge portion that becomes the lower side when the shut damper 20 is closed in the solid line state of FIG.

On the other hand, the seal body 40 is formed in an annular shape as described above, and the connecting portion 42 projecting toward the inside (upper side in the drawing) is integrally formed at a portion corresponding to the escape portion 25 of the damper plate 22. Has been done. The connecting portion 42 has a first
A hole 44 is formed as apparent from FIG. Further, a cut 46 is formed in the coupling portion 42 from the inner circumference of the hole 44 to the left and right.

To assemble the seal body 40 to the damper plate 22,
First, the inner peripheral portion of the seal body 40 is fitted into the groove 26 formed in the edge portion 24 (24A) of the damper plate 22.
As a result, as shown in FIG. 3, the seal body 40 is assembled to the damper plate 22 with the outer periphery of the damper plate 22 being trimmed. In this state, the joint portion 42 of the seal body 40 is located at a position corresponding to the entire escape portion 25 of the edge portion 24A of the damper plate 22.

Therefore, as shown in FIG. 3 and FIG. 4, the connecting portion 42 of the seal body 40 is connected to the damper plate 22 by the holes 44.
And the locking protrusions 30 are coupled to each other. This connection is made by using the notch 46 in the hole 44 of the connecting portion 42 and the locking projection.
The head 30a of 30 is inserted. As a result, the locking protrusion 30 and the hole 4
The head portion 30a of the locking projection 30 holds the number 4 in a retaining state.

As described above, in this embodiment, the locking projection 30 of the damper plate 22 and the coupling portion 42 of the seal body 40 constitute a coupling means. And by this connecting means, the shut damper
On the lower side of 20, the damper plate 22 and the sealing body 40 are firmly connected to each other. Therefore, due to the self-weight of the seal body 40 or the vibration applied to the shut damper 20, the seal body 40 has a lower edge portion of the damper plate 22.
It is eliminated that it falls off the groove 26 of 24A and hangs downward. Therefore, when the shut damper 20 is closed as shown by the solid line in FIG. 5, the shut damper 20 and the air passage 12 are closed.
The airtightness between the inner wall and the inner wall of the body is maintained appropriately.

Second Embodiment FIGS. 6 to 8 show different embodiments of the connecting means for holding the seal body 40 in place. First, as is clear from FIG. 6, the damper plate 22

A pair of pressing pieces 34 projecting from the left and right to the communicating portion 32 are integrally formed at approximately the middle portion in the vertical direction of the communicating portion 32. On the other hand, as is apparent from FIG. 6, the seal body 40 is integrally formed with a vertically continuous connecting portion 48 at a position corresponding to the communicating portion 32 of the damper plate 22. Therefore, as in the case of the first embodiment, when the inner peripheral portion of the seal body 40 is fitted into the groove 26 of the damper plate 22, the connecting portion 48 causes the connecting portion 32 of the damper plate 22 to communicate.
And is locked by the pressing piece 34 (see FIGS. 7 and 8).

Third Embodiment FIGS. 9 and 10 show a modification of the second embodiment. As you can see from these drawings, the damper plate
The pressing piece 34 formed on the communication portion 32 of 22 may be omitted.

In the above-mentioned second and third embodiments, the joint portion 48 of the seal body 40 itself serves as a joint means for holding the seal body 40 from the groove 26 of the damper plate 22 so as not to fall downward.

In addition, in the second and third embodiments shown in FIGS. 6 to 10, members which are considered to have the same or equivalent configurations to those of the first embodiment are designated by the same reference numerals in the drawings, and the duplicated description will be omitted. .

[Effect of device]

The present invention prevents the seal body from coming off from the groove of the lower edge during opening / closing operation even when the dimension of the damper plate in the left-right direction is large, so that the air-tightness between the air passage of the register and the shut damper is prevented. Despite the ability to be maintained properly, the work of assembling the seal body to the damper plate can be easily performed as before.
