Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a vehicle door checking device, and more particularly to a vehicle door checking device that eliminates the generation of abnormal noise.

[Prior Art] Generally, a vehicle door check device includes a check member fixed to either the door or the vehicle body, a mounting bracket fixed to the other of them, and a pivot pin attached to the mounting bracket. When the door is opened and closed centering on the hinge center, the middle abdomen in which the base end is pivotally attached via the ridge and the raised portion is formed is formed of a link plate that is elastically sandwiched by the check member. The link plate and the link member are moved relative to each other, and the check action is performed by utilizing the sliding resistance or pressure contact resistance between the raised portion and the check member.

Conventionally, a check member in such a vehicle door check device is a cover member a as shown in a half section in FIG.
A guide member d that rotatably supports the roller c is provided between the case and the case member b, and an elastic body e is interposed behind the guide member d to sandwich the link plate f via the roller c. I am trying.

[Problems to be solved by the device]

However, in the conventional apparatus shown in FIG. 7, it is common that both the cover member a and the case member b are processed by press molding, and the guide member d is resin molded. Since the dimensional accuracy between the space formed by the case member and the case member b and the guide member d is not sufficient, the cover member a or the case member b can be used.
The gap g shown in FIG. 7 must be present between the guide member d and the guide member d.

If such a gap g exists, for example, when the check member and the link plate move relative to each other when the door is opened and closed,
When the roller c reaches the raised inclined portion of the link plate f, the guide member d rotates, and a corner thereof abuts the cover member a or the case member b, resulting in a problem that abnormal noise is generated.

In order to prevent this, if the dimensional accuracy is increased, the cost increases, and if the guide member d is set to a large size, it may be impossible to assemble the cover member a and the case member b.

SUMMARY OF THE INVENTION An object of the present invention is to solve the problems of the conventional device and to provide a vehicle door checking device capable of preventing the generation of abnormal noise without increasing the cost.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention provides a check member in which a guide member for rotatably supporting a fixed roller of either a door or a vehicle body is housed between a cover member and a case member, and an abdomen. A link plate having a raised portion formed on its side and sandwiched between rollers of the check member; and a check device for an automobile door, comprising: at least one of contact surfaces of the guide member with the cover member and the case member. It is characterized in that a tapered projection is provided on the.

[Action]

According to the present invention, the tapered projection is provided on at least one of the contact surfaces of the guide member with the cover member and the case member.

Therefore, when the guide member is housed between the cover member and the case member, for example, even if the guide member tries to rotate, the guide member is supported by the tapered protrusion to prevent the guide member from rotating, and abnormal noise is generated due to collision. Is prevented. Even if the dimensional accuracy is a little poor, the projections are tapered, so that the tip end is not crushed during assembly, which makes it impossible to assemble or become inoperable.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

1 to 4 show an embodiment of the present invention.

In the figure, 10 is a check member, and from behind, in a space formed by a cover member 11 fixed to a door component member (not shown) and a case member 12 in which a flange portion is joined to this cover member 11, A guide member (14) biased by the elastic members (13, 13) and rollers (15, 15) rotatably supported by the guide members (14, 14) are provided. The case member 12 is formed by drawing with a press and has a screw hole 12
A is provided.

Reference numeral 20 is a link plate formed by stacking two upper and lower plates 20A and 20B, which is inserted into the check member 10 and is a roller.
A stopper 22 is provided which is held by 15 and 15 and has a buffer body 21 at the tip.

Further, each of the link plates 20A and 20B is formed with a raised portion 23A and 23B in the middle abdomen, through the pivot pin 26 inserted into the sleeve 25 attached to the pin holes 24A, 24B at the base end, It is pivotally attached to a mounting bracket 27 that is fixed to a pillar or the like on the vehicle body side.

Next, the guide member 14 will be described in detail with reference to FIGS.

The guide member 14 has a longitudinal portion 14B having a fitting concave portion 14A that rotatably supports the above-mentioned roller 15 in the central portion and plate portions at both ends thereof.
14C and 14C, tapered projections 14D on both sides of the plate portions 14C and 14C, and integrally molded with resin. still,
The fitting recess 14A is provided with a groove as shown in order to smooth the axial movement of the roller 15.

In this embodiment having the above structure, the elastic member 13 and the roller
The guide member 14 to which the 15 is attached is housed in the space formed by the cover member 11 and the case member 12, and then the two are joined to perform the assembly.

At this time, the tip ends of the protrusions 14D provided on both sides of the plate body portion 14C of the guide member 14 have the tips of the cover member 11 and the case member 1
Abut 2. Since the projection 14D is tapered, even if there is some dimensional error between the space and the guide member 14 described above, the tip of the projection 14D is crushed according to the dimensional error, It cannot be disabled.

In addition, as the check member 10 and the link plate 20 move relative to each other as the door is opened and closed, and the roller 15 reaches the raised inclined portion of the link plate 20, even if the guide member 14 tries to rotate, a protrusion is generated.
As it is supported by 14D, rotation is blocked. Therefore, the guide member 14 and the cover member 11 or the case member 12
The occurrence of abnormal noise is prevented without collision with and.

Next, another embodiment of the present invention is shown in FIGS.

In the present embodiment, the projection 14D of the strip body is provided over the entire length of both sides of the plate portions 14C, 14C in the previous embodiment, whereas the projections 14E, 14E, ... It was done like this.

Since the other structure is the same as that of the previous embodiment, the same parts are designated by the same reference numerals to avoid redundant description.

This makes it easy to maintain the posture of the guide member 14 in the space described above.

[Effect of device]

As is clear from the above description, according to the present invention, the rotation of the guide member can be prevented without increasing the dimensional accuracy, so that the generation of abnormal noise can be prevented without increasing the cost.
