Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of an automobile door checker.
[0002]
[Prior art]
In general, as shown in FIG. 3A, an automobile door checker has one end of a check plate 1 pivotally attached to a bracket 4 of a vehicle body 3 with a pin 2 and the other end attached to a door 5 with a screw 6. The guide member 7 passes through the guide member 7 and is elastically supported in the vertical direction by a pair of guides accommodated in the guide member 7.
[0003]
The check plate 1 is formed with ridges 1a and 1a extending in the length direction across the half-open position F of the door 5, respectively. The half-open position F between the ridges 1a and 1a is A moderation recess 1b that fits into the pair of guides of the guide member 7 and holds the door 5 in the half-open position F is formed. A stopper portion 10 is provided at the other end portion of the check plate 1 so as to abut against the guide member 7 and hold the door 5 in the fully open position G.
[0004]
In recent years, the check plate 1 is configured by covering a metal core with a synthetic resin material or molding the whole with a synthetic resin material. The stopper portion 10 is integrally formed of a synthetic resin material. It is molded into.
[0005]
[Problems to be solved by the invention]
The stopper portion 10 is preferably in contact with the guide member 7 in a face-to-face manner. However, the stopper portion 10 may come into contact with one another as shown in FIG. There was a possibility that the offset load was applied to 10 and the stopper portion 10 was damaged as shown in FIG.
[0006]
The present invention has been made to solve the above problems, and an object of the present invention is to provide an automotive door checker that can reliably prevent a stopper portion made of synthetic resin from being damaged.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, according to the present invention, a stopper portion made of a synthetic resin that comes into contact with a guide member that holds the check plate when the door is fully opened is provided at the other end of the check plate that is pivotally attached to the vehicle body. In the automobile door checker provided integrally,
The check plate is configured by covering a core material with a synthetic resin material, and the stopper portion is integrally formed with the synthetic resin material, and the contact surface of the stopper portion with the guide member is formed in an arc shape. In addition, the present invention provides a vehicle door checker characterized in that a through hole is formed in a core material in the vicinity of the stopper portion so that a synthetic resin material passes above and below the stopper portion .
[0008]
DETAILED DESCRIPTION OF THE INVENTION
According to the present invention, since the contact surface of the stopper portion with the guide member is formed in an arc shape instead of a flat surface, the stopper portion comes into contact with the guide member in a face-to-face manner due to variations in the mounting relation to the vehicle body. Even in such a case, since the arcuate apex, that is, the center of the stopper portion is always in contact with the guide member, an offset load does not act on the stopper portion.
[0009]
The check plate is constructed by covering the core material with a synthetic resin material, and through holes are made in the core material near the stopper portion so that the synthetic resin material passes above and below the stopper portion. Will be reinforced.
[0010]
【Example】
Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. In addition, the same number is attached | subjected to the location of the same structure and an effect | action as the prior art of FIG. 3, and detailed description is abbreviate | omitted.
[0011]
As shown in FIG. 1, the check plate 1 is not specifically illustrated, but is configured by covering a metal core with a synthetic resin material, and the stopper portion 12 has the other end of the check plate 1. It is integrally formed with the synthetic resin material to be coated. The entire check plate 1 may be made of a synthetic resin material, and the stopper portion 12 may be integrally formed with the synthetic resin material at the other end of the check plate 1.
[0012]
The contact surface 12a of the stopper portion 12 to the guide member 7 is formed in an arc shape having a relatively small radius R as shown in FIG.
[0013]
With the above configuration, when there is no variation in the mounting relationship with the vehicle body and the stopper portion 12 abuts against the guide member 7 in a face-to-face manner, as shown in FIG. The arcuate apex a (center of the stopper portion 12) comes into contact with the guide member 7.
[0014]
On the other hand, even when the stopper portion 12 does not come into contact with the guide member 7 in a face-to-face manner due to variations in the mounting relationship with the vehicle body, as shown in FIGS. Since a (center of the stopper portion 12) is circular, it always comes into contact with the guide member 7.
[0015]
Accordingly, the center a of the stopper portion 12 always abuts against the guide member 7 regardless of whether or not the mounting relation to the vehicle body varies. Therefore, the conventional eccentric load does not act on the stopper portion 12 and the stopper is stopped. The breakage of the portion 12 can be reliably prevented. The stopper portion 12 does not need to be reinforced with a reinforcing member or thickened, and can be formed by slightly remodeling an existing mold, which does not increase costs.
[0016]
As shown in FIG. 2 (D), when the check plate 1 is formed by covering a metal core 13 with a synthetic resin material 14, the core 13 near the stopper portion 12 is long. When the hole-shaped through hole 13a is formed so that the synthetic resin material 14 passes above and below the stopper portion 12, the stopper portion 12 is reinforced, and damage can be prevented more reliably.
[0017]
【The invention's effect】
As is clear from the above description, the automotive door checker of the present invention has a variation in the mounting relationship to the vehicle body by forming the contact surface of the synthetic resin stopper portion to the guide member in an arc shape, Even when the stopper part does not contact the guide member face-to-face, the arcuate apex (center of the stopper part) always comes into contact with the guide member, so an offset load does not act on the stopper part. It becomes possible to prevent damage to the parts reliably.
[0018]
Also, through holes were made in the core material near the stopper part of the check plate so that the synthetic resin material passed above and below the stopper part, the stopper part made of synthetic resin was reinforced and the stopper part was damaged. It becomes possible to prevent more reliably.
