Abstract

PURPOSE: To reduce the number of part items, cost and assembling manhours and improve workability in a register with specified operating load generated at the time of operating a wind direction deflecting plate. CONSTITUTION: A register is provided with a body case of approximately square cylinder shape. A wind direction deflecting plate 5C formed of a plate part and a shaft parts 7C, 7C' is disposed at the body case 2 and connected by a connecting rod 12. The upper shaft part 7C' of the wind direction deflecting plate 5C is formed into tapered shape with the diameter enlarged downward. A corresponding shaft hole 11 is formed in cylindrical shape, and a C-shape protrusion 14 is formed around the shaft hole 11. It is so set that the distance L2 between wall plates 2a, 2b after the fit-in of the wind direction deflecting plate 5C is larger than the distance L1 between the wall plates 2a, 2b before the fit-in of the wind direction deflecting plate 5C. Accordingly, when the wind direction deflecting plate 5C is fitted in, part of the protrusion 14 comes in pressure contact with the tapered shaft part 7C'. Sliding resistance in a rotating direction is thereby generated between the shaft part 7C' and the shaft hole 11 even not through separate parts such as a shim.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a register installed in, for example, an interior of an automobile to adjust a blowing direction of air conditioning.

[0002]

2. Description of the Related Art Conventionally, as a technique of this kind, a register is provided at a front end portion of a blower duct.
As shown in FIG. 3, a main body case 41 having a substantially rectangular tube shape is provided. A plurality of (four in the figure) fixed plates 42 extending in the horizontal direction are integrally provided in parallel at a front portion of the main body case 41. Further, in the main body case 41, a plurality of (five in the figure) wind direction deflecting plates 43 extending in the vertical direction.
Are provided in parallel.

Each wind direction deflection plate 43 is a flat trapezoidal plate-shaped portion 4
4 and a shaft portion 45 protruding vertically from the plate portion 44
It has and. By fitting the shaft portions 45 into the shaft holes 46 formed in the main body case 41, the wind direction deflecting plate 43 is rotatably supported with respect to the main body case 41. Also, the rear end of each wind direction deflector 43 has a connecting rod 4
They are interconnected by 7. Further, an operation lever 48 protruding forward is provided from the wind direction deflecting plate 43 located at the center. Then, the driver or the like operates the operation lever 48, so that all the wind direction deflection plates 43 are
Is rotated around the shaft 45 in the operating direction. As a result, the wind from the rear passes through the air duct and wind direction deflector 4
As a result, the direction of the wind blown from the front end of the main body case 41 is adjusted.

By the way, when the operation lever 48 is moved,
It is necessary to set a predetermined load. That is, it is necessary to generate sliding resistance associated with the rotation of the wind direction deflecting plate 43.
Therefore, in the above-described conventional technique, as shown in FIGS. 12 and 13, a shim 49 is provided between the shaft portion 45 on one side (for example, the upper side) of the wind direction deflecting plate 43 located at the center and the shaft hole 46 corresponding thereto. A load-setting member called ". The shim 49 is made of a resin material (for example, perprene) having a slight elasticity, and includes an engaging portion 50 and a flange portion 51 having a non-circular cross section. Further, a through hole 52 having a diameter slightly smaller than that of the shaft portion 45 is formed in a substantially central portion of the shim 49. Further, the shaft hole 4
Around the periphery of 6, the engaging concave portion 5 having the same shape as the engaging portion 50.
3 is formed.

Then, with respect to the through hole 52 of the shim 49,
The shaft portion 45 is fitted. Also, the engaging portion 50 of the shim 49
Is engaged with the engaging recess 53. Therefore, when the operation lever 48 is operated, the shaft portion 45 is rotated, whereas the rotation of the shim 49 is restricted by the engagement of the engagement portion 50 with the engagement recess 53. Further, between the outer peripheral surface of the shaft portion 45 and the inner peripheral surface of the through hole 52 of the shim 49, sliding resistance in the rotating direction is generated due to the tightening stress of the shim 49. Therefore, when the operation lever 48 is moved, a predetermined operation load due to the sliding resistance is applied, and the operation feeling can be improved.

The lower surface of the flange portion 51 of the shim 49,
Basically, it is set in advance so that sliding resistance does not occur so much between the wind direction deflecting plate 43 and the upper surface.

[0007]

However, in the above-mentioned prior art, it is necessary to assemble the shim 49 to the shaft portion 45, and the engaging portion 50 of the shim 49 is engaged with the engaging concave portion 53. There was a need. Therefore, the number of assembling steps is increased, and the assembling workability is deteriorated. Further, since the shim 49 is provided, the number of parts is increased and the manufacturing cost is increased.

The present invention has been made to solve the above problems, and an object thereof is to reduce the number of parts in a register constructed so that a predetermined operation load is generated when operating the wind direction deflector. Accordingly, it is an object of the present invention to provide a register capable of reducing the cost and the number of assembling steps and improving the assembling workability.

[0009]

In order to achieve the above object, in the invention described in claim 1, a main body case which is arranged in a blower duct and allows passage of wind from rear to front, and a plate. In the main body case, the main body case is provided with a shaft portion projecting in a direction away from each other from the plate-shaped portion and the plate-shaped portion, and the shaft portion is fitted into a shaft hole formed inside the opposing wall plate of the main body case. And a wind direction deflecting plate rotatably supported in the register, wherein one of the shaft hole and the shaft portion is formed in a tapered shape in which the diameter is expanded toward the inside of the main body case, The other is formed into a tubular shape or a columnar shape, and the distance between the wall plates after fitting the wind direction deflecting plate is set to be longer than the distance between the wall plates before fitting the wind direction deflecting plate, Of the shaft portion and the shaft hole And as its gist that give rise to sliding resistance of the rotating direction of the shaft portion.

According to the second aspect of the invention,
A main body case that is disposed in the air duct and allows passage of wind from rear to front, and a plate-shaped portion and a shaft portion that protrudes in a direction away from the plate-shaped portion, the shaft portion being the main body. The wind direction deflecting plate rotatably supported in the body case and a part of each of the wind direction deflecting plates are connected to each other by being fitted into the shaft holes formed inside the opposite wall plates of the case. A coupling member and at least one
A register having an operating lever provided so as to project forward with respect to one of the wind direction deflecting plates, wherein a tapered shape in which one of the shaft hole and the shaft portion is expanded toward the inside of the main body case. And the other is formed in a cylindrical or columnar shape, and the distance between the wall plates after the air direction deflecting plate is fitted is longer than the distance between the wall plates before the air direction deflecting plate is fitted. The gist is that the sliding resistance in the rotation direction of the shaft portion is generated between the shaft portion and the shaft hole.

[0011]

According to the invention described in claim 1, the wind direction deflecting plate having the shaft portion fitted in the shaft hole formed inside the opposing wall plates of the main body case rotates in the main body case. Can be done. Therefore, the wind blown through the air duct flows along the wind direction deflection plate, and the wind blown forward from the main body case is deflected according to the rotating direction of the wind direction deflection plate.

Here, one of the shaft hole and the shaft portion is formed in a tapered shape whose diameter is expanded toward the inside of the main body case, and the other is formed in a cylindrical shape or a columnar shape, and The distance between the wall plates after fitting the wind direction deflecting plate is set to be longer than the distance between the wall plates before fitting the wind direction deflecting plate. Therefore, when the wind direction deflecting plate rotates, sliding resistance occurs in the rotation direction of the shaft between the shaft and the shaft hole. Therefore, a predetermined operation load is generated for the turning operation of the wind direction deflecting plate without using a load setting means such as a shim that has been conventionally required.

Further, according to the invention of claim 2,
In addition to the effect according to claim 1, the operation lever provided so as to project forward with respect to at least one wind direction deflecting plate is operated to rotate the one wind direction deflecting plate. . Further, since a part of each wind direction deflecting plate is connected to each other by the connecting member, all wind direction deflecting plates are rotated by rotating one wind direction deflecting plate.

Behind the fixed plate 3 in the main body case 2, a plurality of (in this embodiment, five) wind direction deflecting plates 5A, 5B, 5C, 5D and 5E extending in the vertical direction are arranged at equal intervals in the left and right directions. They are arranged in parallel. Each wind direction deflection plate 5A ~
5E is a plate-shaped portion 6 and shaft portions 7A, 7B, 7C, (7 which are formed so as to project vertically from the plate-shaped portion 6 on the same straight line.
C ′), 7D, 7E, and a connecting shaft portion 8 protruding at the lower rear end of the plate-shaped portion 6. Here, the shaft portions 7A to 7E other than the shaft portion 7C 'on the upper portion of the wind direction deflecting plate 5C located in the central portion are formed in a cylindrical shape.

Shaft holes 11 corresponding to the shaft portions 7A to 7E (including 7C ') are formed inside the upper and lower wall plates 2a and 2b of the main body case 2, respectively. And the shaft portion 7
The upper and lower ends of A to 7E and 7C 'are fitted in the shaft holes 11. Further, a connecting rod 12 as an elongated connecting member is attached to the left and right of the connecting shaft portion 8. That is, the rear end portion of each of the wind direction deflecting plates 5A to 5E has the connecting rod 1
Connected by two.

An operating lever 13 is integrally provided at approximately the center of the wind direction deflecting plate 5C located at the center. The operating lever 13 is in a state of protruding somewhat from the front surface of the main body case 2, and a driver or the like operates the protruding portion of the operating lever 13.

The operating lever 13 is operated by the driver or the like.
When is moved, first, the wind direction deflecting plate 5C rotates about the shaft portions 7C and 7C 'with respect to the main body case 2. Further, when one wind direction deflecting plate 5C is rotated due to this rotation, all the wind direction deflecting plates 5A to 5E are simultaneously rotated by the connecting rod 12.

The above-mentioned structure is basically the same as the structure of the air outlet grill in the prior art, and the characteristic part of this embodiment will be described in detail below. FIG. 1 is a cross-sectional view showing the mounting structure of the upper part of the wind direction deflecting plate 5C. In the same figure, a shaft portion 7C 'on the upper side of the wind direction deflecting plate 5C is formed in a tapered shape in which the inner diameter of the main body case 2 (the lower portion in the drawing) is expanded. On the other hand, the corresponding shaft hole 11
Is formed in a cylindrical shape, and a planar C-shaped projection 14 is formed around the shaft hole 11. And
The shaft portion 7C ′ is guided from the rear (right side in the figure) portion where the protrusion is small, so that the shaft portion 7C can be easily fitted into the shaft hole 11.

Further, as shown in FIG. 4, in this embodiment,
From the distance L1 between the wall plates 2a and 2b before fitting the wind direction deflecting plate 5C (the distance between the portion where the shaft portion 7C ′ of the upper shaft hole 11 abuts and the bottom portion of the lower shaft hole 11 in the figure), The distance L2 between the shaft portions 7C and 7C '(the distance between the portion of the shaft portion 7C' that contacts the shaft hole 11 on the upper side of the shaft portion 7C 'and the tip portion of the shaft portion 7C) is set to be larger. However, the distance L is actually
1 and the length of the distance L2 are "0.01 mm" to "2.
0 mm ", preferably" 0.05 m
m "to" 1.0 mm ", and most preferably" 0.1 ".
mm "to" 0.2 mm ", which is difficult to recognize with the naked eye. Therefore, as shown in FIG.
The distance L2 between the wall plates 2a and 2b after fitting the wind direction deflecting plate 5C is larger than the distance L1 between the wall plates 2a and 2b before fitting the wind direction deflecting plate 5C.
Further, when the shaft portions 7C ′ and 7C of the wind direction deflecting plate 5C are fitted into the shaft hole 11, a part of the protrusion 14 comes into contact with the tapered shaft portion 7C ′ in a pressed state. In particular, sliding resistance in the rotating direction of the shaft portion 7C 'is generated between the shaft portion 7C' and the shaft hole 11. In the present embodiment, when the wind direction deflecting plate 5C is attached, the other part of the protrusion 14 also comes into contact with the disc-shaped portion above the plate-shaped portion 6. There is.

Next, the register 1 configured as described above
The operation of will be described. First, when assembling the register 1, the connecting rod 12 is attached to the connecting shaft portion 8 as shown in FIG. Next, the shaft portions 7A to 7E (7C ') of the wind direction deflecting plates 5A to 5E are fitted into the shaft holes 11. By this fitting, the register 1 is obtained.
In this embodiment, it is not necessary to separately attach a load setting member such as a shim used in the prior art. Therefore, the assembling work can be significantly simplified and the workability can be improved. Also, the number of parts can be reduced,
Therefore, the manufacturing cost can be reduced.

Further, the shaft portion 7C 'on the upper side of the wind direction deflecting plate 5C.
Is formed in a taper shape, and as shown in FIGS. 4 and 5, the wall plates 2a, 2 after the wind direction deflecting plate 5C is fitted.
The distance L2 between b is set to be larger than the distance L1 between the wall plates 2a and 2b before the wind direction deflecting plate 5C is fitted. Therefore, when the register 1 is used, a part of the protrusion 14 comes into contact with the tapered shaft portion 7C ′ in a pressed state, and when the operation lever 13 is moved, the shaft portion 7C ′ and the shaft hole 11 are moved. There is a sliding resistance in the rotating direction of the shaft portion 7C 'between and. Therefore, it is possible to generate a load equivalent to the conventional load without separately mounting a load setting member such as a shim.

Further, in the present embodiment, when the wind direction deflecting plate 5C is attached, the other part of the protrusion 14 is replaced by the plate-like portion 6.
It also comes into contact with the disk-shaped portion on the upper part of. For this reason, sliding resistance due to friction also occurs at the contact portion, and it is possible to further secure the stability of load setting.

Further, in this embodiment, the sliding resistance can be arbitrarily and easily changed by appropriately changing the angle of the tapered surface. In addition, in the present embodiment, even if there is some dimensional error in the height direction of the wind direction deflecting plate 5C including the shaft portion 7C ', the angle of the tapered surface should be set appropriately. Thereby (for example, by setting the inclination angle small), the above error can be absorbed in a state where the sliding resistance in the rotating direction is hardly influenced.

The present invention is not limited to the above embodiment, but may be configured as follows, for example. (1) In the above-described embodiment, when the wind direction deflecting plate 5C is attached, the other part of the protrusion 14 also contacts the disc-shaped portion above the plate-shaped portion 6. However, as shown in FIG. 7, there is no problem even if only a part of the protrusion 14 is in contact with the tapered shaft portion 7C ′.

(2) In the above embodiment, the upper shaft portion 7C 'of the wind direction deflecting plate 5C is formed in a tapered shape and the shaft hole 11 is formed in a cylindrical shape. However, the relationship between the two 7C' and 11 is reversed. May be. That is, as shown in FIG. 8, the shaft hole 16 may be formed in a tapered shape whose diameter increases toward the body case 2 side, and the shaft portion 17 may be formed in a columnar shape. Even with such a configuration, the same operational effects as those of the above-described embodiment can be obtained.

Further, as shown in FIG. 9, the shaft portion 18 may be formed in a tubular shape having a hollow portion 19. With such a configuration, the shaft portion 18 can be bent to some extent, and the length direction of the shaft portion 18 (the height direction of the wind direction deflecting plate 5C).
It is possible to absorb the variation of.

(3) In the above embodiment, the body case 2 having a substantially rectangular tube shape is adopted, and the length of the wind direction deflecting plate 5C in the direction of the shaft portions 7C and 7C 'is longer than the distance between the wall plates 2a and 2b. However, as shown in FIG. 10, the upper and lower wall plates 20a of the main body case 20 (in the figure, the upper wall plate 20a
(only a is shown) is formed inwardly in a concave shape, and a wind deflector is attached to the main body case 20.

mm "is desirable, and" 0.1 mm "to" 0.2 m "
m "is most desirable.

(4) In the above embodiment, the upper shaft portion 7C 'of the wind direction deflecting plate 5C itself has a taper shape, but the upper flange portion 21 of the wind direction deflecting plate 5C is regarded as the shaft portion, and the flange The portion 21 may have a tapered shape. Even in such a case, the same operational effect as that of the above-described embodiment can be obtained.

(5) In the above embodiment, the upper shaft portion 7C 'of the wind direction deflecting plate 5C has a tapered shape, but the lower shaft portion 7C may have a tapered shape. Further, both the upper and lower shaft portions 7C and 7C 'may be tapered. Further, the configuration of the main part of this embodiment may be adopted for any of the other wind direction deflecting plates 5A to 5E, and the number thereof may be plural.
