Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for preventing vertical rattling of a door in a door lock for an automobile door which is pivotally mounted to a vehicle body with a vertical axis.

Conventional devices of this type include those shown in FIGS. 1 to 3.

In this device, a lock body d is provided at the middle part of the free end of an automobile door c which is pivotally attached to a car body (not shown) with a hinge b having a vertical axis a, and a lock body d is provided in the middle part of the free end of the car door c, which is pivoted to a car body (not shown) with a hinge b having a vertical pivot a. A striker e with a U-shaped planar shape is fixed to the center pillar side of the vehicle body, and the striker e is inserted into the lock body d when the door is closed.
A wedge-shaped pressing body g, commonly called a wedge bumper, having an inclined surface f that comes into contact with the lower surface of the free end of the door is provided so as to be slidable in the inward and outward directions of the door c, and this pressing body g is directed toward the inside of the vehicle with a spring h. When the door is closed, the lower surface of the free end of the striker e is pressed upward by the inclined surface f of the pressing body g, and the striker e is pressed against the latch member i, which causes the door c to move in the vertical direction. I try to prevent rattling. Examples of such prior art include Japanese Utility Model Application Publication No. 43436/1983.

However, in such a conventional device, the free end of the striker e is pressed upward by the inclined surface f of the pressing body g, and the middle part of the striker e is engaged with the latch member i. When the door is closed, a large bending stress is generated in the striker e, which is not favorable in terms of strength.Furthermore, due to the deformation of the hinge b, etc., phenomena such as door upward movement or door downward movement, which causes the free end of the door c to shift in the vertical direction, have occurred. In this case, the bending stress generated in the striker e becomes large, and there is a fear that the striker may become bent or damaged.

In view of the drawbacks of the conventional devices as described above, the present invention provides a U-shaped striker on the vehicle body side with the horizontal part facing upward, and a pressing body provided on the door side on the upper surface of the horizontal part of the striker. An automobile in which the pressing surfaces are brought into contact to prevent the door from rattling in the vertical direction, so that the pressing force of the pressing body acts only in the axial direction of the striker, and no bending stress is generated on the striker. The purpose of this device is to provide a device for preventing rattling of a door lock.
Description will be given based on the embodiment shown in FIGS. 7 to 7.

Reference numeral 1 designates an automobile door, and this door 1 is pivotally attached to a vehicle body 4 with a hinge 3 having a vertical pivot shaft 2.

A lock body 5 is provided at the lower part near the free end of the door 1, and a striker 6 is provided on the floor side of the vehicle body 4 corresponding to the lock body 5.

The striker 6 has a downward U-shape consisting of a horizontal part 6a facing in the same direction as the opening/closing direction of the free end of the door 1, and legs 6b, 6c hanging down from both ends of the horizontal part 6a. It is erected on a base plate 7 fixed to the floor of the vehicle body 4.

The lock body 5 includes a horizontal base plate 8 fixed to the door 1, and a substantially U-shaped striker entrance 9 opening toward the inner edge of the vehicle is bored in the center of the base plate 8. ing.

A latch member 11 is mounted on the base plate 8 behind the striker entrance 9 with a vertical axis 10.
However, the base plate 8 in front of the striker entrance 9 has a pawl member 1 with a vertical axis 12.
3 are pivoted to each other.

As shown in FIGS. 4 to 7, the striker 6 entering the striker squid entrance 9
The door 1 is closed by blocking the rotation of the latch member 11 in the opening direction (counterclockwise direction in FIG. 6) with the pawl member 13 while the latch member 11 is engaged with the leg portion 6b on the outside of the vehicle. By maintaining this state and rotating the pawl member 18 in the counterclockwise direction in FIG. It is designed so that the door 1 can be opened by leaving the door 9.

In order to disengage the latch member 11 and the pawl member by rotating the pawl member 13 counterclockwise in FIG. Although this release means is used, illustration and detailed description thereof will be omitted since it is not directly related to the present invention.

The latch member 11 is biased counterclockwise in FIG. 6, and the pawl member 13 is biased clockwise in FIG. 6 by appropriate springs. , illustration is omitted.

Reference numeral 14 denotes a cover plate that covers the upper part of the striker 6 that has entered the striker entrance 9. Both sides of the cover plate are fixed to the upper ends of the shafts 10 and 12, and the center portion bulges upward 14a.

The upper piece 14b of the central bulging part 14a of the cover plate 14 has an inclined shape with its outer side end facing upward, and at both ends there are bent pieces 14 facing substantially downward.
c and 14d are bent at right angles.

Both ends of an inclined shaft 15 that is parallel to the upper piece 14b are fixed to both bent pieces 14c and 14d, and a pressing body 16 that slides in contact with the lower surface of the upper piece 14b is attached to the shaft 15 in the axial direction. It is slidably fitted.

A pressing surface 16a whose outer side end curves slightly downward is formed on the lower surface of the pressing body 16, and this pressing surface 16a comes into contact with the upper surface of the horizontal portion 6a of the striker 6 when the door is closed, thereby pushing the striker 6. Press downward.

A compression coil spring 17 is installed around the shaft 15 between the bent piece 14c on the outside of the vehicle and the pressing body 16.
is compressed, and the pressing body 16 is always urged toward the inside of the vehicle by the spring 17.

Since this embodiment has the above-described configuration, when the door is closed, the pressing body 16 is pressed by the spring 17 and forms a wedge between the upper surface of the horizontal portion 6a of the striker 6 and the lower surface of the upper piece 14b of the cover plate 14. the striker 6 on the pressing surface 16a of the pressing body 16.
By pressing the horizontal portion 6a downward, it is possible to prevent the door 1 from shaking in the vertical direction.

At this time, the pressing force on the striker 6 by the pressing body 16 is directed in the same vertical direction as the axial direction of the legs 6b and 6c, so only a compressive force acts on the striker 6, and almost no bending stress is generated. This can be said to be a mechanically favorable structure.

In addition, in this embodiment, when a vertical positional deviation occurs between the lock body 5 and the striker 6, the pressing body 16 slides along the lower surface of the upper piece 14b to correct the positional deviation. It has the effect of compensating.

As is clear from the above, in the present invention,
In addition to installing the striker in the vertical direction,
When the door is closed, the pressing surface of the pressing body provided on the door side comes into contact with the upper surface of the horizontal part of the striker, thereby preventing the door from shaking in the vertical direction. This is significant because the durability of the striker can be improved without causing this problem.

In the above embodiment, the striker is provided on the floor side of the vehicle body, and the pressing surface of the pressing body is in contact with the upper end surface of the striker. A pressing body is supported on a door lock provided on a sash at the top of the free end of the door so as to engage and disengage from this, and the pressing surface of this pressing body is in contact with the lower end surface of the striker, thereby allowing the upper and lower parts of the door to It may be arranged to prevent directional wobbling.

Further, such a loop side device and the device of the above-described embodiment may be arranged side by side to form a vertically symmetrical structure, and the door may be sandwiched from above and below to prevent the door from shaking in the vertical direction. .

Further, in the above embodiment, the pressing body is made to be able to slide along the inclined upper piece of the cover plate, but the pressing body is made of an elastic body and is fixed directly to the cover plate of the door lock, etc. It's okay. In this case, it is better if the pressing surface of the pressing body is inclined upward toward the inside of the vehicle.
