Description

  The present invention relates to a vehicular register for introducing air into a passenger compartment.

  For a vehicle register, for example, the technique disclosed in Patent Document 1 is already known. In this technique, a support piece having elasticity is provided on a bush that rotatably supports a back fin (vertical fin) of a register. When the shaft portion of the back fin is inserted into the hole opened in the support piece, the stepped surface of the shaft portion contacts the support piece and the support piece is pushed. Thereby, the dimension error of the location which the support piece elastically deforms and supports the back fin is absorbed.

JP 2010-132204 A

In the technique disclosed in Patent Document 1, although it is possible to absorb a dimensional error in a component unit such as a back fin or a bush by elasticity of a support piece, a bush and a mating member (register) to which the bush is assembled. It is not possible to close the gap between the retainer and the retainer. In particular, in a bush having a large size in the depth direction of the register (front-rear direction of the vehicle), if there is a gap at a location apart from the coupling portion with the retainer, the bush will rattle and cause noise.
As a countermeasure, for example, if a protrusion for closing the bush is provided carelessly, the support load of the fin by the bush increases by the amount that the bush is pushed away from the retainer by the protrusion. As a result, the load when rotating the fin to adjust the wind direction at the air outlet increases.

  The present invention is intended to solve such a problem, and an object of the present invention is to prevent the occurrence of abnormal noise by suppressing backlash of the bush without increasing the operation load when rotating the fin. .

The present invention is for achieving the above object, and is configured as follows.
A vehicle equipped with a retainer constituting an air passage, a fin for adjusting a wind direction at an air outlet of the retainer, and a bush mounted inside the retainer so that the fin can be rotated. Of the bushes that individually support both ends of the fin, at least one of the bushes is provided with a protrusion that actively interferes with the retainer in a state of being assembled inside the retainer. A flexure is provided that elastically deforms when the projection interferes with the retainer.

  More preferably, the bending portion is configured by providing slits penetrating both surfaces of the bush, and the protrusion is configured by projecting a part of the bending portion toward the retainer.

  More preferably, a retainer that constitutes an air passage, a fin for adjusting the wind direction at the air outlet of the retainer, and a bush that is supported so that the fin can be rotated and assembled to the interior of the retainer. A vehicular register provided with a protrusion that actively interferes with the end of the fin at least one of the bushes that individually support both ends of the fin; And a bending portion that is elastically deformed by interfering with the end portion.

  The flexure is configured by providing slits that penetrate both sides of the bush near the support hole that supports the fin, and the protrusion is configured by projecting the periphery of the support hole toward the end of the fin. It is.

In the present invention, the gap of the bush with respect to the retainer can be reduced by causing the projection of the bush to interfere with the retainer and elastically deforming the bent portion, and without increasing the operation load when rotating the fin, It is possible to prevent the generation of abnormal noise by suppressing the rattling.
In addition, by providing the bush with a structure in which a protrusion is provided on a bent portion constituted by a slit, it is possible to avoid a significant design change of the bush and to keep the structure simple.

Furthermore, in the present invention, the protrusion of the bush is made to interfere with the end of the fin and the bent portion is elastically deformed so that the gap of the bush with respect to the retainer can be reduced without increasing the operation load when rotating the fin. The occurrence of abnormal noise can be prevented by suppressing backlash of the bush.
In addition, this function is provided by having a function of closing the gap between the retainer and the bush by means of a bent portion formed near the support hole in the bush and a protrusion formed by protruding the periphery of the support hole. Are concentrated near the fin axis, avoiding significant design changes of the bushing and maintaining a simplified structure.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
First, a first embodiment of the present invention will be described with reference to FIGS.
The vehicle register R has an appearance shown in FIGS. 1 to 3 and is assembled to an instrument panel (not shown) on the front side in the vehicle. The cylindrical retainer 10 constituting the outer shell of the register R is connected to an air-conditioning duct (not shown) at one end inside the instrument panel, and an air outlet 12 having the other end facing the vehicle interior. It has become. The periphery of the air outlet 12 is decorated with a bezel 14, and the retainer 10 is coupled to the instrument panel through the bezel 14.

Inside the air outlet 12 in the retainer 10, a plurality of front fins 16 positioned on the vehicle inner side and a plurality of back fins 20 positioned on the back side of the front fins 16 are provided. The front fins 16 are arranged in a substantially horizontal posture. On the other hand, the back fins 20 are arranged in a substantially vertical posture.
Both ends of each front fin 16 are rotatably supported by left and right bushes (not shown) assembled to the retainer 10. Further, the front fins 16 are connected by connecting rods (not shown) so as to rotate in conjunction with each other. On the other hand, the support structure of each back fin 20 is shown in FIGS.

As is apparent from FIGS. 4 to 6, each back fin 20 has a shaft portion 20 a at both upper and lower end portions, and has a connecting pin 20 b at a position shifted from the shaft portion 20 a at the upper end portion. The shaft portions 20a at both the upper and lower ends of each back fin 20 are rotatably supported by the upper and lower bushes 22 and 30 assembled to the retainer 10, and the respective back fins 20 rotate in conjunction with each other. The connecting pin 20 b is connected by a connecting rod 26.
Although the illustration of the support structure of the front fin 16 is omitted as described above, the upper and lower support structures of the back fin 20 are substantially changed to the left and right support structures.

One of the front fins 16 is provided with a fin knob 18 at a substantially intermediate position between the left and right. In addition, the fin knob 18 can slide to the left and right with a predetermined stroke with respect to the front fin 16, and is a fork that engages with an engagement shaft 20 c formed on one back fin 20 on the inner side of the retainer 10. Shaped nails (not shown) are provided.
Therefore, by operating the fin knob 18 in the vertical direction together with the single front fin 16, the other front fins 16 are also rotated in the vertical direction in conjunction with each other. Further, by sliding the fin knob 18 in the left-right direction, one back fin 20 having the engagement shaft 20c and the other back fins 20 interlocking with the left and right fins 18 are moved to the left and right around the axis of each shaft portion 20a. Rotate in the direction. By rotating the front fins 16 and the back fins 20, the direction (wind direction) of the air blown into the vehicle from the air outlet 12 can be adjusted up and down and left and right.

Inside the retainer 10, a damper plate 44 is provided on the back side of each back fin 20 (FIGS. 4 and 5). The damper plate 44 is supported so as to be rotatable about the rotation axis 45 with respect to the retainer 10, and the amount of air blown into the vehicle from the air outlet 12 is adjusted by adjusting the rotation angle.
A damper knob 46 is rotatably attached to the left outer wall of the retainer 10. The damper knob 46 can be rotated by exposing a part of the damper knob 46 on the surface side of the bezel 14 (FIGS. 1 to 3). By rotating the damper knob 46, the damper plate 44 is rotated around the rotation axis 45 through the link mechanism 48.

The lower bush 30 that supports each back fin 20 is configured to suppress rattling in a state where it is assembled to the retainer 10. Therefore, the configuration of the bush 30 will be described in detail mainly with reference to FIGS.
The bush 30 has a plurality of support holes 32 that support the lower shaft portion 20 a of each back fin 20. On the back surface of the bush 30, a pair of left and right engaging portions 34 are provided near the inner edge of the vehicle, and a pair of left and right claws 36 are provided near each support hole 32 (FIG. 9). Both engaging portions 34 are positioned by engaging with ribs inside the bezel 14 (FIG. 4), and both claws 36 engage with holes in the bottom plate of the retainer 10 (FIG. 5).

Near the rear edge of the bush 30, a pair of left and right slits 38 penetrating both surfaces of the bush 30 are provided. By these slits 38, a pair of flexures 40 is formed at the inner edge of the bush 30. That is, these flexures 40 have a structure like a “both-supported beam” having elasticity. And both the bending parts 40 are provided with the protrusion 42 which protruded below in each substantially intermediate part.
Both protrusions 42 are set to project dimensions that overlap the inner surface of the bottom plate of the retainer 10 when the bush 30 is assembled inside the retainer 10, and actively interfere with the inner surface of the bottom plate (FIG. 4). The force acting on the bush 30 when these protrusions 42 interfere with the retainer 10 causes the respective bent portions 40 to be elastically deformed.

  Regarding the assembly order of the bezel 14, the front fin 16 and the back fin 20 in the assembly work of the register R, the front fins 16 are assembled after the back fins 20 are assembled to the retainer 10, and finally the bezel 14 Assemble. Each back fin 20 is assembled to the retainer 10 in a state in which the shaft portions 20a at both ends are supported by the upper and lower bushes 22 and 30 and the connection pin 20b of each back fin 20 is connected by the connection rod 26. As described above, each front fin 16 is also supported by the bushing and connected by the connecting pin in the same manner as the inner fin 20, and is assembled to the retainer 10 in this state.

  In order to assemble each of the rear fins 20 supported by the upper and lower bushes 22 and 30 and connected by the connecting rod 26 to the retainer 10, first, the upper bush 22 is positioned on the retainer 10, and then the lower bush 30 is moved. It is assembled so as to be pushed into the retainer 10 (FIG. 12). Thereby, as already explained, both claws 36 of the bush 30 are engaged with the holes in the bottom plate of the retainer 10 and positioned. Further, the bush 30 is also positioned with respect to the bezel 14 assembled to the retainer 10 by the engagement of the pair of engaging portions 34 as described above (FIG. 4). However, the inner edge of the bush 30 is only received by the bottom plate of the retainer 10, and if there is a gap between them, the gap causes the backlash of the bush 30.

In this embodiment, the bush 30 is assembled inside the retainer 10, so that the pair of left and right protrusions 42 positively interfere with the bottom plate inner surface of the retainer 10 as described above. Due to this interference, the gap between the inner edge of the bush 30 and the inner surface of the bottom plate of the retainer 10 is reduced to suppress the backlash of the bush. Is absorbed by elastic deformation. For this reason, it is possible to prevent a load from being applied between the shaft portion 20a of each back fin 20 and each support hole 32 of the bush 30, and the operation load when rotating each back fin 20 is kept at the set value. Be drunk.
Further, since the bent portion 40 is formed by providing the slit 30 in the bush 30 and the protrusion 42 is formed on the bent portion 40, a significant design change of the bush 30 is avoided, and the bush 30 is formed. Changes such as adding a slide mold to the mold are also unnecessary.

Next, a second embodiment of the present invention will be described with reference to FIGS. In these drawings, members that are considered to have the same or equivalent configuration as those in the first embodiment described above are denoted by the same reference numerals as those in the first embodiment, and redundant description will be omitted.
The lower bush 30 that supports each back fin 20 in the second embodiment is also configured to suppress rattling in a state where it is assembled to the retainer 10. That is, the bush 30 is provided with slits 50 penetrating both surfaces of the bush 30 on both sides of the plurality of support holes 32 that support the lower shaft portion 20a of each back fin 20 (FIG. 15). . Due to these slits 50, the periphery of each support hole 32 is a bent portion 52, and these bent portions 52 have a structure like a “double-supported beam” having elasticity.

  Further, the periphery of each support hole 32 on the surface side of the bush 30 is a protrusion 54 protruding upward, that is, toward the lower end portion of each back fin 20. Each of these projections 54 positively interferes with the lower end portion of each back fin 20 in a state where each back fin 20 is assembled together with the upper and lower bushes 22 and 30 and the connecting rod 26 inside the retainer 10. (FIG. 13). When these protrusions 54 interfere with the lower end portions of the respective back fins 20, the pressing force acting on the bush 30 elastically deforms the respective bending portions 52.

Also in the register R of the second embodiment, in the state where the bush 30 is assembled inside the retainer 10, each protrusion 54 interferes with the lower end portion of each back fin 20, thereby The gap between the retainer 10 and the inner surface of the bottom plate can be reduced to prevent the bush from rattling. And the pushing-down force which acts on the bush 30 by interference of each protrusion 54 is absorbed when the bending part 52 of each location elastically deforms. As a result, as in the case of the first embodiment, it is possible to prevent a load from being applied between the shaft portion 20a of each back fin 20 and each support hole 32 of the bush 30, and when rotating each back fin 20 An increase in operating load is prevented.
Further, in the second embodiment, the function of suppressing the backlash of the bush 30 by the bent portions 52 formed in the vicinity of the support holes 32 in the bush 30 and the projections 54 projecting from the periphery of the support holes 32. Therefore, this function can be concentrated in the vicinity of the rotation axis of each back fin 20. For this reason, the design change of the bush 30 is avoided as in the first embodiment, and a change such as adding a slide mold to the mold for molding the bush 30 becomes unnecessary.

Although the best mode for carrying out the present invention has been described above with reference to the drawings, this embodiment can be easily changed or modified without departing from the spirit of the present invention.
For example, in the first and second embodiments, it is configured so as to be packed between the lower bush 30 and the retainer 10 on the back fin 20, but depending on the shape of the upper bush 22, the bush 22 and the retainer 10 It is also possible to replace with a configuration that closes the gap between the two. Moreover, you may employ | adopt the structure which closes a clearance gap between upper and lower bushes 22 and 30. FIG.
Furthermore, it is also possible to employ a configuration in which a gap between the retainer 10 and a bush (not shown) that supports the front fin 16 is filled as required.
