DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile door check device.

[0002]

2. Description of the Related Art In a conventional door check device M of this type, as shown in FIG. 9, a locking pin 93 is fixed to a penetrating end of a check arm 1 via a holding plate 92. The check arm 1 was prevented from coming off the holder 2.

[0003]

However, in such a conventional door check device M, the holding plate 92 is fixed by hooking the locking pin 93 to the tip of the check arm 1. The number of parts increases in maintaining the retaining of 1,
As a result, there is an inconvenience that assembling is troublesome and maintenance is troublesome.

An object of the present invention is to eliminate such inconvenience.

[0005]

In order to achieve the above object, in a door check device according to the present invention, a check arm for swingably mounting a pillar of a vehicle body and a holding arm mounted on a door of the vehicle body are provided. A door check device for an automobile, wherein the check arm is penetrated through the holder, and a retaining member is provided at a penetrating end of the check arm to prevent the check arm from falling out of the holder. Since the retaining member is provided on the check arm and the retaining member is covered with the coating layer, the exposed portion is eliminated, and as a result, it is resistant to rust, and the coating layer exhibits the function of an elastic material. Only by penetrating the arm through the holder, the check arm can be assembled to the holder,
It is possible to reduce the number of components of the retaining portion (stopper portion) and, consequently, the number of assembly steps.

[0006] The check arm may be covered with a coating layer different from the coating layer of the retaining member.

Further, the check arm may be covered with a covering layer of the same material as the covering layer of the retaining member.

[0008] The coating layer may be a synthetic resin layer.

The coating layer of the retaining member is made of TPE.
A layer (elastomer) layer can increase the elastic force.

7 is a perspective view of the same, and FIG. 8 is a front sectional view of the third embodiment.

In FIG. 1 to FIG. 5, M denotes a door check device, which comprises a check arm 1 and a holder 2. The retainer 2 is used by being fixed to a door plate 3 of an automobile. Specifically, a screw 31 is attached to the door plate 3.
Be stopped. On the other hand, the check arm 1 is used such that its rear end (left end in FIG. 1) is swingably attached to a pillar (of the vehicle body) of an automobile, and a tip end portion thereof moves forward and backward to the holder 2. Penetrate as possible.

Reference numeral 5 denotes a case of the holder 2, and 6 denotes a lid of the holder 5. Reference numeral 50 denotes a through hole formed substantially at the center of the bottom of the case 5, and reference numeral 61 denotes a through hole formed in the lid 6.
The check arm 1 passes through the case 5 and the cover 6 through the through holes 50 and 61.

Next, reference numerals 51, 51 denote a pair of nipping roller tools, which are disposed in the case 5 via support members 511, 511. The pair of holding roller members 51, 51 are opposed to each other, are urged toward each other by the rubber members 52, 52 toward the center, and hold the check arm 1. The check arm 1 moves back and forth against this pinching.

Reference numeral 11 denotes a locking hole, which is formed at the tip of the check arm 1 (corresponding to the "through projection" of the present invention). Further, reference numeral 7 denotes a stopper (corresponding to a “preventing member” of the present invention), which is fitted into the locking hole 11 of the check arm 1. This stopper 7
Prevents the check arm 1 from falling off the holder 2.

Reference numeral 8 denotes a resin layer (corresponding to the “coating layer” of the present invention), which integrally covers the surface of the stopper plate 7. With this resin layer 8, the metal stopper 7 can prevent rust. On the other hand, the portion of the resin layer 8 that covers the stopper plate 7 fixes the stopper plate 7 to the check arm 1 to prevent the stopper plate 7 from coming off with respect to the check arm 1, and the rear surface of the case 5. Can function as an elastic material.

Note that a TPE layer (having an intermediate property between a rubber material and a resin material) may be provided in place of the resin layer 8.

FIGS. 6 and 7 show a second embodiment, in which the check arm 1 is further covered with another resin layer 81. FIG. By doing so, the rust of the check arm 1 can be prevented, and the sliding of the check arm 1 with respect to the nipping roller tools 51, 51 can be improved. Numerals 53, 53 denote a pair of holding members, which correspond to the holding roller members 51, 51 of the first embodiment. Reference numerals 12 and 13 denote through holes formed in the check arm 1, and the resin layer 81 penetrates to strengthen the adhesion of the resin layer 81.

FIG. 8 shows a third embodiment, in which the check arm 1 is integrally covered with a resin layer 8 covering the surface of the stopper plate 7.

[0019]

The door check device according to the present invention includes a check arm for swingably mounting a pillar on a vehicle body and a holding tool for mounting on the door of the vehicle body, and penetrates the check arm through the holding tool. Then, in a door check device for an automobile, in which a retaining member is provided at a penetrating end of the check arm to prevent the check arm from coming off from the holder, the retaining member is provided on the check arm. Since the retaining member is covered with the coating layer, the exposed portion is eliminated, so that it is resistant to rust, and furthermore, the coating layer exhibits the function of an elastic material. The arm can be assembled to the holding tool, and the number of parts of the retaining portion (stopper portion) can be reduced,
As a result, the number of assembly steps can be reduced.

Therefore, if this door check device is used, the production efficiency of the door check device can be improved, and the maintenance after installation in the vehicle is easy.

The check arm may be covered with a coating layer different from the coating layer of the retaining member.

Further, the check arm may be covered with a covering layer of the same material as the covering layer of the retaining member.

Further, the coating layer may be a synthetic resin layer.

The coating layer of the retaining member is made of TPE.
A layer (elastomer) layer can increase the elastic force.
