Description

[Detailed Description of the Invention] This invention relates to a wedge device for a sliding door of a vehicle.

Conventionally, this type of wedge device has a catch hole drilled in the opening of the vehicle body, a thick-tipped striker formed in the slide door, and the striker enters the catch hole when the slide door is closed. Yes (Utility Model Publication No. 54-77324).

However, in the conventional device described above, the striker simply fits into the catch hole, and cannot absorb the rattling of the slide door that occurs when the slide door is closed, and if there is an error in the mounting position of the catch hole and the striker, the slide door will close. At times, there is a risk that this wedge device may be damaged, so the mounting position must be adjusted accurately, and the adjustment is complicated. In addition, the sliding door
Generally, it is stabilized and held at a position slightly returned from the point of maximum penetration.

This idea was made in view of the problems of the conventional ones as described above. On the other hand, by providing a flexible protrusion, it is possible to prevent rattling when the sliding door is closed, and there is no risk of damage to the wedge or striker.Moreover, the wedge of the sliding door of the vehicle is easy to install. The purpose is to provide equipment.

An embodiment of the present invention will be described below with reference to the drawings.

1 and 2 show a first embodiment of the present invention. In the figures, a sliding door 3 is attached to a vehicle body opening 2 formed near the center of both sides of a vehicle 1. The sliding door 3 is attached to the vehicle 1.
It is slidable back and forth along a center guide rail 4 formed on the side surface of the vehicle 1 and upper and lower guide rails (not shown) provided above and below the vehicle 1. Further, 5 is a wedge, which is formed from a thin iron plate or the like by, for example, press molding, and has a convex portion 5c having a U-shaped cross section and a flange portion 5a extending on both sides of the convex portion 5c, This flange portion 5a is fastened and fixed to the door abutting surface 2a of the vehicle body opening 2 with bolts 5b.

Reference numeral 6 denotes a striker made of synthetic resin or the like, and the striker 6 includes a recess 6c surrounded by a peripheral wall 6e and flange portions 6 extending on both sides of the peripheral wall 6e.
The flange portion 6a is fastened to the front end surface 3a of the sliding door 3 with bolts 6b. The shape of the concave portion 6c is such that it can be tightly engaged with the convex portion 5c of the wedge 5, and a through hole 6f is formed in the peripheral wall 6e, and the peripheral wall of the through portion outside of the through hole 6f is formed in the peripheral wall 6e. 6
The thickness of e' is reduced, and a flexible protrusion 6d is formed at the upper end of the peripheral wall 6e' of the penetrating portion so as to face inward of the recess 6c.

Next, the effects will be explained. When the sliding door 3 is closed, the protrusion 5c of the wedge 5 enters the recess 6c of the striker 6 while pressing the flexible protrusion 6d, and at the maximum intrusion, the protrusion 6d moves to the position shown in FIG. 2b. As shown, the projection 5c of the wedge 5 is pressed against the inner surface of the peripheral wall 6e' of the penetrating portion, so that the projection 5c of the wedge 5 is tightly pressed into engagement with the recess 6c of the striker 6.

Furthermore, when the sliding door 3 returns a little from the maximum penetration position, a slight gap is created between the convex part 5c of the wedge 5 and the concave part 6c of the striker 6, but the protrusion 6d is As shown in FIG. 2c, the protrusion 5c is pressed against the inner surface of the peripheral wall 6e on the opposite side of the protrusion 6d, so the sliding door 3 does not shake, and in this way the protrusion 6d can absorb the above gap.

In addition, in the installation work of the wedge device, the wedge 5 is tightened and fixed in a predetermined position on the door contact surface 2a with the bolt 5b, and the striker 6 is fixed with the bolt 5b.
After lightly tightening and temporarily fixing the slide door 3 to the front end surface 3a of the slide door 3 using b, the slide door 3 is strongly closed. Then, the striker 6 and the wedge 5 are tightly engaged as shown in FIG. Installation work can be done extremely easily.

Furthermore, even if there is some error in the mounting positions of the wedge 5 and the striker 6, the error is absorbed by the flexible protrusion 6d.
The wedge device will not be damaged when closed.

FIG. 3 shows a second embodiment of the present invention, in which the same reference numerals as in FIG. 2 indicate the same parts. In this embodiment, a projection 6d' is formed using a part of the peripheral wall 6e, and the projection 6d' is formed by reducing the thickness of the peripheral wall 6e and bending it inward into the recess 6c. This thinner material has flexibility.

In this second embodiment, when the sliding door 3 is closed, the protrusion 5c of the wedge 5 enters the recess 6c of the striker 6 while pressing the protrusion 6d'. As a result, the convex portion 5c and the concave portion 6c are tightly pressed and engaged. Furthermore, even if a gap is created between the convex portion 5c and the concave portion 6c, the protrusion 6d' will recover to absorb this gap.
The sliding door 3 does not rattle.

Furthermore, in this embodiment, when the striker 6 is molded from synthetic resin using a mold, it can be easily removed from the mold.

FIG. 4 shows a third embodiment of the present invention, in which the same reference numerals as in FIG. A portion of the convex portion 5c of the wedge 5 is cut and raised, and as a result, it naturally has flexibility.

In this third embodiment, the sliding door 3
When closed, the protrusion 5d touches the recess 6 of the striker 6.
c and is deformed inwardly, whereby the convex portion 5c of the wedge 5 and the concave portion 6c of the striker 6 are tightly pressed and engaged. Also, the convex portion 5c and the concave portion 6
Even if there is a gap between the protrusion 5 and the
d is restored to absorb this gap, so the sliding door 3 does not rattle.

As described above, according to the wedge device for a sliding door of a vehicle according to the present invention, a flexible protrusion is formed on one of the engagement surfaces of the wedge and the striker, and the wedge is engaged with the wedge when the sliding door is closed. Since the protrusion is deformed and pressed into engagement with the striker, when the sliding door is closed, the door returns a little from its maximum penetration position, creating a gap between the protrusion of the wedge and the recess of the striker. Even in such a case, the protrusion restores its original shape by the amount of the gap due to its flexibility and absorbs the gap, which has the effect of preventing the sliding door from rattling.

In addition, in the installation work of the wedge device, it is sufficient to forcefully close the slide door with the striker temporarily secured, to tightly engage the striker and the wedge, and then tighten and secure the striker in this state. The effect is that it can be done extremely easily.

Furthermore, even if there is a slight error in the mounting positions of the wedge and the striker, the error is absorbed by the flexible protrusion, so there is an effect that the wedge device will not be damaged when the sliding door is closed. .
