Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a door checker device provided in a mounting portion of a door of an automobile.

[Conventional technology]

Conventionally, as a vehicle door checker device, for example, one disclosed in Japanese Utility Model Laid-Open No. 57-29783 is known. This is because the mail plate 3 having a stopper 32 for receiving at one end is formed on the door 1 as shown in FIG.
The mail plate 3 is attached to the vehicle body 2 so as to be rotatable around a vertical axis 31.

As shown in FIG. 7, the check case a is composed of a case body b and a cover c. The case body b has a box-shaped accommodating portion d and an attachment formed by projecting above and below the opening of the accommodating portion d. It is composed of a piece e. In general, the case body b accommodates a shoe f that guides the mail plate 3 from above and below, and an elastic member g that urges the shoe f to press the mail plate 3 side. A cover c is attached to this by caulking or spot welding. The check case a is attached to the door 1 by a bolt h penetrating the attachment piece e.

[Problems to be solved by the device]

In the above-mentioned conventional vehicle door checker device, since the case body b and the cover c are both made of steel, rust may occur over time, or noise may occur due to sliding or interference between metals. It may occur. There is also a demand for weight reduction and cost reduction as vehicle parts. Also, the case body b is bent.
Since the accommodating portion d is formed into a box shape, its corners are rounded, and the elastic member g inside may flow into the gap i with the cover c (see the alternate long and short dash line in FIG. 7).

Therefore, it can be considered that the case body and the cover are made of synthetic resin. However, in this case, since the case body made of synthetic resin generally has a lower strength than that made of steel, the mounting piece e bends at its base portion due to the pressure from the elastic member, so that the opening of the case body comes out of the cover. There is a risk of floating up. In this case, the elastic member g
The gripping force on the mail plate 3 due to the force may be reduced, and it may not be possible to obtain a moderation sensation when opening the door.

The present invention has been made in order to solve such conventional problems, and can achieve weight reduction, cost reduction, and the like, without causing abnormal noise due to sliding or interference between metals. An object of the present invention is to provide a vehicle door checker device that can prevent rusting and can reliably prevent deformation of a check case.

[Means for Solving the Problems]

In order to achieve the above object, according to the present invention, a vehicle door checker having a check case attached to a door and a mail plate penetrating the check case and having one end rotatably attached to a vehicle body about a vertical axis. In the device, the check case includes a case body and a cover, and the case body and the cover are integrally formed of synthetic resin, and the case body has a box-shaped housing portion and a side surface of the housing portion. From the mounting piece that is formed to project outward from the mounting portion, and the angle formed between the mounting piece and the housing portion does not change at the corner formed by the mounting piece and the housing portion, and Reinforcing ribs are formed integrally to keep the cover and the case body in surface contact with each other, and are locked to either the cover or the case body. There while being projected, locking holes corresponding to the locking pawl is configured so as to be provided on the other.

[Action]

According to the above configuration, since the check case is made of synthetic resin, it can be made lighter than steel, and can be expected to reduce cost because it is suitable for mass production. It is possible to reliably prevent the generation of rust without generating abnormal noise due to sliding or interference between metals. Moreover, since the deformation of the mounting piece of the case body is restricted by the reinforcing ribs, the check case can be reliably prevented from being deformed.

Further, since either one of the cover and the case main body is provided with a locking claw and the other is provided with a locking hole corresponding to the locking claw, the locking claw faces the locking hole. The cover and the case body are connected to each other only by pressing them against each other, and as a result, the opening of the housing does not float up from the cover, and the cover and case body are always properly connected.

〔Example〕

In the first embodiment shown in FIG. 2, the door 1 has a rotation center A.
At the position, the pillar (vehicle body) 2 is rotatably connected about a vertical axis, so that the door 1 opens outward (upper side in the drawing) around the rotation center A. Again door 1
The pillar 2 and the pillar 2 are regulated by the mail plate 3 so that the opening angle of the door 1 is within a predetermined range.

As shown in FIG. 3, the mail plate 3 is formed by a pair of strip-shaped plates 30 so that the thickness thereof changes in the vertical direction, and one end of the mail plate 3 penetrating the check case 4 is attached to the pillar 2 around a vertical axis 31. It is rotatably mounted. A stopper 32 is formed on the other end of the mail plate 3, and the stopper 32 is arranged inside the door 1 as shown in FIG.

The check case 4 is attached to the inner panel of the door 1 by means of mounting bolts 8, and inside the shoe, shoes 51 are provided on the upper and lower sides of the mail plate 3 as shown in FIG. The elastic member 52 for urging to the 3 side is stored, and the door 1 is guided so as to move smoothly along the mail plate 3.

The check case 4 is composed of a case body 6 and a cover 7 as shown in FIG. 1, and the case body 6 and the cover 7 are coupled to each other by engagement of a locking claw 71 and a locking hole 61. I am trying to do it.

The case body 6 has a box-shaped housing portion 62 that opens laterally, a mounting piece 63 that projects vertically from an opening edge 621 of the housing portion 62, and is hooked between the mounting piece 63 and the housing portion 62. The reinforcing ribs 64 having a substantially triangular shape are integrally formed of a synthetic resin, and the insertion hole 622 of the mail plate 3 is formed in the inner surface of the accommodating portion 62, and the mounting bolts 8 are attached to the upper and lower mounting pieces 63. Mounting holes 631 are formed so as to penetrate therethrough.

A protrusion 623 is formed on the outer surface of the accommodating portion 62 along the hole edge of the insertion hole 622, and a haunch portion 624 is integrally formed on each side of the protrusion 623. . As a result, the opening edge of the insertion hole 622 is reinforced.

The reinforcing ribs 64 are integrally formed on both sides in the width direction of the case body 6 in a concave corner portion formed by the mounting piece 63 and the upper and lower wall surfaces of the housing portion 62 (side surfaces of the housing portion). 63 and the accommodating portion 62 are reinforced so that the mutual intersecting angle is maintained at about 90 °.

In addition, the upper and lower mounting pieces 63 include the opening edge 6 of the accommodation portion 62.
Two locking holes 61 are formed so as to penetrate along 21.

The cover 7 is made of synthetic resin and has a size that shields the upper and lower mounting pieces 63 of the case body 6 and the housing portion 62.
The cover 7 is formed with a through hole 72 for the mail plate 3 at the center thereof and a mounting hole 73 for mounting bolts at the upper and lower portions thereof. Further, on the cover 7, projecting edges 74 are formed so as to project in a direction orthogonal to the cover surface 75 from both side edges in the width direction, and a plurality of locking claws 71 corresponding to the locking holes 61 project in the direction. Is integrally formed.

As shown in FIG. 3, the locking claw 71 is formed with a claw portion 711 at a position protruding by the thickness of the mounting piece 63, and the claw portion 711 locks with the edge of the locking hole 61. As a result, the case body 6 and the cover 7 are positionally fixed in a state of being in contact with each other.

The mounting bolt 8 for mounting the case body 6 and the cover 7 on the door 1 has a serration portion 81 at the base thereof.
The serration portion 81 is press-fitted into the mounting hole 631 of the case body 6 to fix the position of the mounting bolt 8.

In the vehicle door checker device having the above-described configuration, the check case 4 includes a pair of shoes 51 and an elastic member 52 which are vertically arranged inside the housing portion 62 of the case body 6, and a mail plate which passes between these upper and lower parts. 3 is penetrated, and in this state, the locking claw 71 of the cover 7 is fitted into the locking hole 61 of the case body to lock the claw portion 711 at the hole edge, so that the case body 6 and the cover 7 are coupled to each other. It is assembled and assembled. As a result, the shoe 51 and the elastic member 52 are prevented from falling out of the housing portion 62 of the case body 6, and the compression restoring force from the elastic member 52 acts on the inner surface of the housing portion 62.

Then, the mounting bolts 8 are inserted into the respective mounting holes 631 and 73. At this time, the serration portion 8 of the mounting bolt 8
By press-fitting 1 into the mounting hole 631 of the case body 6, the serration portion 81 and the inner peripheral surface of the mounting hole 631 mesh with each other, whereby the mounting bolt 8 is fixed in position with respect to the check case 4. To be done.

As shown in FIG. 2, the check case 4 in the assembled state is attached to the inner surface of the door 1 by the attachment bolts 8, and one end of the mail plate 3 is attached to the pillar 2 by the vertical shaft 31.
The installation of the door checker device is completed by mounting it on the.

In the door checker device, the check case 4 moves along the mail plate 3 as the door 1 is opened and closed. During this movement, when the vertical thickness of the mail plate 3 increases, the elastic member 52 is compressed, and this compression restoring force acts on the inner surface of the housing portion 62 and the cover 7. As a result, the accommodating portion 62 of the case body 6 and the cover 7 tend to move away from each other, and a bending force acts on the mounting piece 63 with the mounting bolt 8 as a reaction point.

However, since the mounting piece 63 is regulated by the reinforcing rib 64 so as to maintain the relative angle with the housing portion 62,
Even if the accommodating portion 62 and the like are made of synthetic resin to have a relatively thin wall thickness, the cover 7 and the case body 6 are kept in contact with each other, and the check case 4 is not deformed. This allows the elastic member 52 to exert a predetermined biasing force on the mail plate 3.

Further, since the upper and lower walls of the accommodation portion 62 are positionally fixed so that the opening edge 621 portion which is the base thereof is not separated from the cover 7 by the claw portion 711 of the locking claw 71, the opening portion of the accommodation portion 62 is formed. Does not float up from the cover 7, and the deformation of the case body 6 can be reliably prevented.

Further, they are locked to each other only by causing the locking claw 71 to face the locking hole 61 and pressing them against each other, whereby the case body 6 and the cover 7 can be coupled to each other. Therefore, the work of connecting the case body 6 and the cover 7 can be easily performed, and the connected state can be reliably maintained. Further, at the time of the above-mentioned joining work, by applying the inner surface of the protruding edge 74 to both side edges of the case body 6 in the width direction, the positioning in the width direction can be performed, and the above-mentioned joining work can be easily performed.

Further, when the check case 4 moves along the mail plate 3, the hole edge of the insertion hole 622 may contact the surface of the mail plate 3. Even in this case, since the hole edge is reinforced by the protrusion 623 and the haunch portion 624, it is not deformed by being dragged by the mail plate 3.

Further, as the door checker device before being mounted on the door 1, the mail plate 3, the mounting bolts 8 and the like can be preliminarily integrally assembled, which facilitates the handling of the door checker device on the vehicle. In addition, since the mounting bolt 8 does not rotate together when the nut 83 (see FIG. 2) is tightened, the above-described mounting work can be easily performed.
