It is rotatably mounted around a vertical axis 31.

The above-mentioned check case a is composed of a case body b and a cover c, as shown in FIG. A cover c is attached to the opening of the case body b by caulking or spot welding, and the above-mentioned show d is inserted through this opening. It is made to not fall off.

[The problem that the idea attempts to solve]

In the above-mentioned conventional automobile door checker device, since the case body b and the cover c are both made of steel, rust may occur over time, and metals may make noise due to sliding or interference with each other. may occur. Furthermore, there are demands for weight reduction and cost reduction as vehicle parts.

Therefore, it is conceivable to form the case body and the cover from synthetic resin. However, in this case, it is not possible to connect the case body and the cover by welding, so it is necessary to connect them to each other by means other than welding.

In addition, if the pair of case body b and cover c are separate parts, it is inconvenient in terms of parts management, and if they are one part, it is inconvenient in terms of parts management, and one part is easily lost. There is. Furthermore, when assembling the case body and the cover together, it is necessary to adjust their positions so that their predetermined joint surfaces face each other, and this requires time and effort.

This idea was made to solve these conventional problems, and it is possible to reduce weight and cost, and to ensure that there is no abnormal noise caused by sliding or interference between metals. The object of the present invention is to provide a door checker device for an automobile that can prevent the occurrence of rust, allow easy assembly of a check case, and facilitate the management of parts constituting the check case. .

With this structure, the mutual joining positions are automatically determined, thereby facilitating the assembly work.

〔Example〕

In the first embodiment shown in FIG. 2, a door 1 is connected to a pillar (vehicle body) 2 at a rotation center A position so as to be rotatable around a vertical axis. It is designed to open towards the top of the drawing. Further, the door 1 and the pillar 2 are regulated by a 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 band-shaped plates 30 so that the thickness in the vertical direction changes. It is rotatably mounted around the A stopper 32 is formed at the other end of the mail plate 3, and the stopper 32 is arranged inside the door 1 as shown in FIG.

This check case 4 is attached to the inner panel of the door 1 with a mounting bolt 8, and the mail plate 3 is installed inside the case as shown in FIG.
A shoe 51 disposed on both upper and lower sides of the door 1 and an elastic member 52 that urges the shoe 51 toward the mail plate 3 are housed, and guide the door 1 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. 61 and the locking hole 71 so that they are coupled to each other.

The case body 6 has a box-shaped housing part 6 that opens on the side.
2 and a mounting piece 63 that protrudes vertically from the opening edge 621 of this housing part 62 are integrally formed of synthetic resin, and the back surface of the housing part 62 has an insertion hole for the mail plate 3 622, the mounting bolts 8 are attached to the mounting pieces 63 on both the upper and lower sides (see Figure 3).
Attachment holes 631 are formed therethrough.
Furthermore, two locking claws 61 are formed on the left and right outer surfaces of the housing portion 62, respectively, to protrude outward.

The cover 7 is attached to the upper and lower mounting pieces 63 of the case body 6.
The cover 7 is formed of synthetic resin to a size that covers the opening edge 621 of the housing portion 62, and the insertion hole 7 of the mail plate 3 is formed in the center of the cover 7.
2. Mounting holes 73 for mounting bolts are formed through the upper and lower parts. In addition, the cover 7 has
Projecting edges 74 are formed to protrude from both sides in the width direction in a direction perpendicular to the cover surface 75, and a plurality of locking holes 71 corresponding to the locking claws 61 are formed through the projecting edges 74. .

As shown in FIG. 4, the case body 6 and the cover 7 are fixed in position in a mutually contacting state by the locking claw 61 locking with the edge of the locking hole 71.

Further, as shown in FIG. 1, a thin strip-shaped connecting piece 67 is integrally formed at one end of the mounting piece 63 of the case body 6 in the vertical direction and one end of the cover 7 in the vertical direction. The case body 6 and cover 7 are integrally molded from synthetic resin while being connected by a connecting piece 67. The length and mutual forming position of the connecting piece 67 are determined so that the case body 6 and the cover 7 are joined to each other by bending the connecting piece 67 as a hinge, as shown in FIG. .

The mounting bolt 8 for mounting the case body 6 and the cover 7 to the door 1 has a third bolt at its base.
As shown in the figure, a serration section 81 is formed,
By press-fitting this serration portion 81 into the mounting hole 631 of the case body 6, the position of the mounting bolt 8 is fixed.

In order to assemble the check case 4 in the automobile door checker device having the above configuration, the case body 6
A pair of shoes 51 and an elastic member 5 are placed in the housing part 62 of
2 are installed vertically, and in this state, the cover 7 is bent from the connecting piece 67, and the projecting edges 74 on both sides are applied to both outer surfaces of the housing part 62 of the case body 6, and the case body 6 and the cover 7 are joined to each other. Just press in the direction you want. As a result, the locking claw 61 of the case body 6
is engaged with the locking hole 71 of the cover 7, and the case body 6 and the cover 7 are coupled to each other, and the shoe 51 and the elastic member 52 are prevented from falling out of the housing part 62 of the case body 6, and the housing A compressive restoring force from the elastic member 52 acts on the inner surface of the portion 62 .

Then, it passes through the mail plate 3 so as to pass between the upper and lower parts of the case body 6 and the cover 7, and
The mounting bolts 8 are inserted into the respective mounting holes 631 and 73 as shown in FIG. At this time, by press-fitting the serration portion 81 of the mounting bolt 8 into the mounting hole 631 of the case body 6, the serration portion 81 and the inner peripheral surface of the mounting hole 631 are engaged with each other, and thereby the mounting bolt 8
is fixed in position relative to the check case 4.

The assembled check case 4 is attached to the inner surface of the door 1 using the mounting bolts 8 as shown in FIG. The assembly is complete.

In the above-mentioned door checker device, since the case body 6 and the cover 7 that constitute the check case 4 are made of synthetic resin, there is no occurrence of abnormal noise due to sliding or interference between metals, and there is no occurrence of rust. It is possible to reliably prevent this, and it is also possible to reduce the weight compared to a steel check case. Furthermore, cost reduction can be achieved by mass production using resin molding.

In addition, the case body 6 and the cover 7 are connected by a connecting piece 6.
Since they are connected to each other by 7, it is possible to reliably manage the parts in a paired state without losing just one. Moreover, when assembling the case body 6 and the cover 7, the connecting piece 6
Since 7 functions as a hinge, the mutual joining direction is automatically determined, thereby facilitating the assembly work.

Further, the locking claws 61 and the locking holes 71 are locked to each other by simply applying the projecting edges 74 of the cover 7 to both widthwise edges of the case body 6 and pressing them together, whereby the case body 6 and the cover 7 can be combined with each other. At this time, the above-mentioned projecting edge 7
4 allows positioning in the width direction,
This makes it possible to easily connect the case body 6 and the cover 7, and to maintain the connected state reliably.

In addition, the mail plate 3, mounting bolts 8, etc. can be pre-assembled into a single piece as the door checker device before it is installed on the door 1, making it easier to handle when installing 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-mentioned mounting work can be easily performed.

When the door checker device is used, 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. However, since the bases of the left and right side walls of the accommodating portion 62 are fixed in position by the protruding edges 74 of the cover 7 so as not to open from each other, the accommodating portion 62 and the like are made of synthetic resin and are relatively thin. Even if the case body 6 is formed thick, deformation of the case body 6 can be reliably prevented. Thereby, the elastic member 52 can apply a predetermined biasing force to the mail plate 3, and can reliably give the operator a predetermined sense of moderation.

In the first embodiment, the structure of the mounting portion of the mounting bolt 8 between the case body 6 and the cover 7 and the formation position of the locking pawl 61 may be changed as shown in FIG. 5. That is, the cover 7a
A mounting hole 73a having a diameter corresponding to the serration portion 81a of the mounting bolt 8a is formed through the mounting hole 73a, and an annular protrusion 731a that protrudes by the thickness of the mounting piece 63a is formed at the peripheral edge of the mounting hole 73a. . A mounting hole 631a having approximately the same diameter as the outer diameter of the annular protrusion 731a is formed through the mounting piece 63a of the case body 6a. Also, the head 82a of the mounting bolt 8a has a protrusion 731a.
It is formed larger than the outer diameter of.

Further, two locking claws 61a are formed protruding from the upper and lower mounting pieces 63a of the case body 6a along the opening edge 621a of the housing portion 62a.
A locking hole 71a corresponding to the locking claw 61a is formed through the cover 7a.

In the above configuration, the upper and lower walls of the accommodating portion 62a of the case body 6a are the opening edges 621a that are the base thereof.
Since the portion is fixed in position by the locking claw 61a so as not to separate from the cover 7a, even if the compressive restoring force of the elastic member 52 acts on the inner surface of the housing portion 62a or the cover surface 75a, the housing portion The opening of the case 62a does not rise above the cover 7a, and deformation of the case body 6a can be reliably prevented.

In addition, the head 82a of the mounting bolt 8a is attached to the protrusion 7.
By making the outer diameter of the head 82a larger than the outer diameter of the head 82a, when it is attached to the check case 4a, the inner surface of the head 82a is connected to the protrusion 731a and the mounting hole 63.
1a, and thereby the case body 6
The bonding relationship between a and the cover 7a can be further strengthened.

Further, the cover 7a has a protrusion 76a formed on the surface opposite to the attachment surface to the case body 6a so as to protrude more than the protrusion of the locking claw 61a. , the locking pawl 61a is prevented from coming into contact with the mounting surface of the door 1.
