BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for adjusting the wind direction of a vehicle ventilator.

[0002]

2. Description of the Related Art Conventional wind direction adjusting devices of this type include:
As shown in FIG. 7, a plurality of horizontal fins 20 are provided in a front opening (not shown) of a case (not shown), and a plurality of vertical fins 21 are provided behind these horizontal fins 20. The vertical fins 21 are rotatably provided by a support shaft 22.
Are connected by an interlocking member 23 for simultaneously rotating the vertical fins 21 in the same direction, and an operation knob 24 is slidably provided in the horizontal fin 20 in the horizontal direction.
5 and a pinion 2 at the front edge of the vertical fin 21.
6, the rack teeth 27 of the rack 25 are engaged with the tooth portions 28 of the pinion 26, and the operation knob 24 is moved, so that the vertical fin 21 is moved through the rack 25 and the pinion 26 around the support shaft 22. In some cases, the vertical fin 21 is rotated horizontally in the direction of movement of the operation knob 24, and the other vertical fins 21 are rotated through the interlocking member 23 to blow out wind in the direction of movement of the operation knob 24.

[0003]

However, in the conventional example, when the horizontal fin 20 is rotated in the vertical direction, the operation knob 24 is swung up and down by the horizontal fin 20 as shown in FIG. Will be. In this case, the horizontal fin 2
Due to the lack of rigidity of 0, the horizontal fins 20 bend, and the rack teeth 27 of the rack 25 of the operation knob 24 are partially or entirely detached from the teeth 28 of the pinion 26.

Further, as a conventional wind direction adjusting device for a vehicle ventilator, there is one disclosed in Japanese Utility Model Laid-Open Publication No. 58-86713.

The present invention has been made to solve the above-mentioned problem, and it is possible to prevent the rack teeth of the rack from coming off from the tooth portion of the pinion when the horizontal fin is rotated. It is an object of the present invention to provide a wind direction adjusting device for a tar.

[0006]

In order to achieve the above object, the present invention provides a plurality of horizontal fins at a front opening of a case and a plurality of horizontal fins behind these horizontal fins. Vertical fins are rotatably provided by a support shaft, these vertical fins are connected by an interlocking member that simultaneously rotates the vertical fins in the same direction, and an operation knob is provided on the horizontal fin so as to be slidable in the horizontal direction. In a wind direction adjusting device for a vehicle bench radiator in which a rack provided at a rear portion of an operation knob is meshed with a pinion provided at a front portion of a vertical fin, a stopper for preventing the rack and the pinion from being disengaged. Is provided on at least one of the rack and the pinion.

[0007]

With this configuration, when the rack teeth of the rack are to be disengaged from the tooth portions of the pinion due to the rotation operation of the horizontal fins, the stopper is engaged and the meshing and disengagement is prevented.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

FIG. 1 is a front view, partially omitted, of a wind direction adjusting device of a vehicle ventilator according to the present invention, and FIG. 2 is a plan view, with the same parts omitted.

In FIG. 1, reference numeral 1 denotes a case, and a plurality of horizontal fins 3 are arranged at predetermined intervals in a vertical direction at an air outlet 2 which is a front opening of the case 1. The horizontal fins 3 are connected to each other by an interlocking member (not shown), and can be simultaneously rotated and inclined in the same direction via the interlocking member.

A plurality of vertical fins 4 are arranged in the outlet 2 behind the horizontal fins 3 at predetermined intervals in the left-right direction. The case 1 is supported by support shafts 5a and 5b provided at the upper and lower edges, and the rear end is connected to a connecting member 7 by a pin 6.
, And can be simultaneously rotated and tilted in the same direction via the interlocking member 7. A pinion 8 having a flat fan shape is fixed to the front edge of the vertical fin 4 located at the center with its teeth 9 facing forward. An upper portion of the tooth portion 9 of the pinion 8 is cut out to form a stopper insertion portion 15, and an upper end portion of the tooth portion 9 forms a stopper 10.

An operation knob 11 is provided on the horizontal fin 3 to which the tooth portion 9 of the pinion 8 faces so as to be slidable in the axial direction (lateral direction) of the horizontal fin 3.
A rack 12 is provided at the rear of 1. This rack 12
At the center of the upper end on the side of the rack teeth 13, a rib-shaped stopper 14 that is wide in the horizontal direction is formed so as to connect two adjacent rack teeth 13.

The rack teeth 13 of the rack 12 are engaged with the teeth 9 of the pinion 8, and a stopper 14 formed on the rack 12 is provided with a stopper insertion portion 15 of the pinion 8.
It is located above.

Next, the operation will be described.

When the operation knob 11 is moved to the left, for example, the vertical fins 4 are rotated to the left around the support shafts 5a and 5b via the rack 12 and the pinion 8, and other vertical fins are moved via the interlocking member 7. The vertical fins 4 rotate to the left, and blow the wind to the left.

When the operation knob 11 is moved to the right, the vertical fins 4 rotate to the right, and blow the wind to the right.

When the horizontal fin 3 is rotated downward, the operation knob 11 is swung downward by the horizontal fin 3, and the horizontal fin 3 is bent due to insufficient rigidity of the horizontal fin 3, and the operation knob Although some or all of the rack teeth 13 of the rack 12 of the eleventh are going to separate from the teeth 9 of the pinion 8,
In this case, the stopper 14 provided on the rack 12 abuts against the stopper 10 of the pinion 8 to prevent the pinion 8 from being disengaged.

In the above-described embodiment, the stopper 14 is formed on the upper portion of the rack 12 and the upper side of the tooth portion 9 located in the middle on the pinion 8 side is cut out, and the stopper insertion portion 1 is formed.
5, the stopper 10 is provided at the upper end of the tooth portion 9, but a stopper is also provided at the lower portion of the rack 12 so that the pinion 8
The lower side of the tooth portion 9 may be cut out to form a stopper insertion portion, and a stopper may also be formed at the lower end portion of the tooth portion 9.

The means for preventing the engagement and disengagement is not limited to the above-mentioned case of the abutment of the stopper 14 but also to the teeth 13 of the rack 12 and the teeth 9 of the pinion 8 as shown in FIGS. Without any processing, the rack 12
A stopper 16 protruding above the rack teeth 13 is fixed to the center of the upper and lower surfaces, and the horizontal fins 3 are turned up and down to move the rack teeth 13 of the rack 12 from the tooth 9 of the pinion 8. If the pinion 8 is to be disengaged, the stopper 16 may be brought into contact with the upper and lower surfaces of the teeth 9 of the pinion 8 so as to prevent the engagement and disengagement. One side is provided with a stopper (not shown) such as a protruding portion, and the other side is provided with a concave portion (not shown) for receiving the stopper. When the rack teeth 13 of the rack 12 are to be disengaged from the teeth 9 of the pinion 8, the stoppers may be received in the concave portions to prevent the engagement and disengagement.

[0020]

As described above, in the present invention, since the stopper for preventing the rack and the pinion from being disengaged is provided on at least one of the rack and the pinion, the horizontal fin is rotated in the vertical direction. When the rack teeth of the rack are to be disengaged from the tooth portions of the pinion, the stoppers are engaged to prevent the engagement and disengagement.
