DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-color molded outlet grill used in a vehicle.

[0002]

[Prior art]

(1) For example, JP-B-54-26266, JP-B-5-26266
In Japanese Patent Application Laid-Open No. 9-48745, a cylindrical frame having a through-hole for accommodating a large-diameter portion of the tip of the rotating shaft of the movable wind direction deflecting plate is formed in advance, and the melting point is lower than the molding material of the cylindrical frame. The movable wind direction deflecting plate and its rotating shaft are formed of a material having a low diameter [PP (polypropylene)], and a large-diameter end of the rotating shaft is rotatably fitted in a through hole of the cylindrical frame. Is disclosed. (2) Further, for example, Japanese Patent Laid-Open Publication No. 3-225153 discloses a configuration in which a cylindrical frame having a fixed wind direction deflecting plate is formed in front of a movable wind direction deflecting plate having substantially the same shape as in the above (1). Have been. (3) Also, for example, in Japanese Patent Application Laid-Open No. 4-147-149, when a rotating body of a wind direction adjusting device is swung to a predetermined swing angle, as a means for applying torque to a rotating shaft thereof, There is disclosed a configuration in which a case surrounding the tip of the rotation shaft is provided, and the case is filled with a torque generating material. (4) Also, for example, conventionally, using a two-color molding method,
After forming a movable wind direction vertical deflection plate having a rotation axis with a substantially circular cross section at both ends by the process, the surrounding of the movable wind direction vertical deflection plate and swinging of the movable wind direction vertical deflection plate are performed in the subsequent second step. Even if the cylindrical frame body holding the both ends of the rotating shaft can be contracted and deformed at the time of cooling accompanying molding, in order to prevent a load more than a certain level from acting on the rotating shaft, A spring mechanism for releasing the contraction of the cylindrical frame body is employed for the rotating shaft.

[0003]

Conventionally, an appropriate frictional resistance (required) is provided between a rotating shaft of a movable wind direction deflecting plate and a cylindrical frame which rotatably holds the tip of the rotating shaft. An operational resistance when the movable wind direction deflecting plate is swung to a predetermined operation angle is obtained, and a frictional resistance for holding the movable wind direction deflecting plate at a target angle position), that is, an operation load is applied to the rotating shaft of the movable wind direction deflecting plate. We needed a way to do that.

[0004] Here, for example, in the configuration described in (1) and (2) in the section of the prior art, a method using a molding die is described.
After the movable wind direction deflecting plate having the rotation axis is formed in the first step by the color forming method, it is easy to form as a molding resin material in the second step, and it is inexpensive and excellent in cost. PP for molding (for molding the movable wind direction deflecting plate and its rotation axis)
When a barrel composed of a fixed wind direction horizontal deflection plate and a cylindrical frame is molded using (polypropylene),
A PP barrel is easily deformed due to molding distortion and insufficient rigidity.

[0005] For this reason, it has been difficult to apply an appropriate operation load required for the rotating shaft of the movable wind direction deflecting plate. In order to prevent the deformation, an upright reinforcing rib (reinforcement vertical plate) is formed integrally with the cylindrical frame and the wind direction horizontal deflection plate. It is possible to take countermeasures such as using However, when the reinforcing rib is used, the reinforcing rib is visually recognized from the wind outlet of the grill, so that the appearance is poor in design.
In addition, it is difficult to manufacture a mold that accurately estimates the deformation amount.

As means for applying the operation load, for example, the cylindrical frame is forcibly deformed along the axial direction of the rotating shaft of the movable wind direction deflecting plate to urge both ends of the rotating shaft. As described in the related art section (3), it is possible to use a torque generating material to associate the rotating shaft with the rotating shaft. However, these conventional means for applying an operation load have a complicated configuration. Need.

Further, in the configuration of the above-mentioned prior art (4), it is difficult to apply a stable (always constant) operation load to the rotating shaft of the movable wind direction deflecting plate. That is, in the above configuration, for example, even if the cylindrical frame body contracts and deforms in the direction of compressing the rotation axis of the movable wind direction deflecting plate, the contraction is performed by the spring mechanism formed on the rotation axis. It can be elastically absorbed. However, conversely,
When an action force compresses only the rotation axis along the axial direction due to some careless operation, the spring mechanism is contracted, and the spring mechanism is moved in a direction to shorten the total length of the rotation axis. I do. For this reason, one of the two end portions of the rotating shaft cannot get the overlap margin (lap portion) by the cylindrical frame body and comes off, and the movable wind direction deflecting plate comes off from the cylindrical frame body.

Therefore, it is impossible to maintain a state in which a stable operation load is applied to the rotation shaft having the spring mechanism of the movable wind direction deflection plate. The present invention has been made in view of the above circumstances, and can apply a predetermined operation load to the rotating shaft of the movable wind direction deflecting plate in advance at the time of two-color molding, without using a complicated configuration as in the related art. It is an object to provide a two-color molded outlet grill.

【The invention's effect】

(1) Since the two-color molding outlet grilles of the first to third aspects have the operation load control means, the following effects can be obtained. That is, when the movable load direction vertical deflecting plate is rocked to a position where a predetermined rotation angle (target wind direction) is obtained by a forced operation from the outside, the operation load control means reduces the resistance of the rocking operation. A moderate reaction force can be obtained.

Therefore, the operator who performs the swing operation can obtain an operational feeling and can feel the operation. After swinging to the predetermined opening angle position, the operating load means applies a predetermined load to the rotation axis of the movable wind direction vertical deflection plate. Without
The opening angle can be maintained. (2) According to the two-color molded outlet grill of claim 1, the operating load control means is provided with a concave / convex member which is engaged in a concave / convex manner at a contact portion between the movable wind direction vertical deflection plate and the fixed wind direction horizontal deflection plate of the barrel. Because of the joint portion, the movement of the movable wind direction vertical deflection plate along the rotation axis and the movement of the barrel fixed wind direction horizontal deflection plate along the rotation axis can be restricted, and the barrel cylindrical frame body Can reliably be prevented from being deformed.

Therefore, even if the barrel is made of PP, the two-color molded outlet grill of the first aspect can eliminate molding distortion and insufficient rigidity without forming the conventional reinforcing ribs. Does not impair. (3) According to the two-color molded outlet grill of the second aspect, the operating load control means includes one end protruding shaft portion of the rotating shaft of the movable wind direction vertical deflection plate held by the cylindrical frame of the barrel and other components. Since the operation load control means can be constituted by a simple structure in which the end side protruding shaft portion is formed with a grain, it is advantageous in terms of cost. (4) According to the two-color molding outlet grille of the third aspect, the operating load control means is formed at the tip of the rotation axis of the movable wind direction vertical deflection plate held on the cylindrical frame of the barrel, and has a cylindrical shape. Since the front end enlarged portion is buried in the frame and is in sliding contact, even if the spring mechanism is formed on the rotating shaft of the movable wind direction vertical deflection plate, the spring mechanism is abnormally compressed by careless operation. When this is done, the tip of the rotating shaft can be kept buried in the cylindrical frame, and the movable wind direction vertical deflecting plate does not fall out of the cylindrical frame as in the prior art.

Since the enlarged end of the rotating shaft is buried in the cylindrical frame, it is not exposed to the outside and is not visually recognized to improve the appearance quality (appearance).
