Description

[Detailed explanation of the idea] The present invention relates to a mounting bracket for a vehicle sliding door.

The pan-type vehicle door is called a sliding door because it is designed to be opened by pulling it out a little and then sliding it along the side wall of the vehicle.

The present invention particularly focuses on the mounting bracket for the sliding door.
This design has been devised to ensure smooth operation of the guide rolls.

The mounting bracket for the sliding door is designed to allow the sliding door pulled out from the entrance to slide while maintaining a constant distance from the side wall of the vehicle, and to close the door in an arc-shaped trajectory relative to the entrance. It has a plurality of rollers and - guide rolls.

However, when looking at the guide roll of the mounting bracket that was developed before this application, the roll is pivoted in an unchanging state;
Immediately after the door was opened or just before it was closed, the horizontal wheel was used to push it.

Therefore, there was a risk of failure within a short period of time.

Therefore, to explain the devised invention of the present invention, Fig. 2 shows a side view of the inventive mounting bracket, Fig. 3 shows a plan view of the in-use state, and 27 is the door called the above-mentioned sliding door.

The base metal fitting 4 is fixed to the sliding door 27 with bolts 28.

The base metal fitting 4 includes an engaging protrusion 5 that partially stands up at a right angle,
5, and the engaging protrusions 5, 5 are provided with a through hole through which a shaft 3, which will be described later, is inserted.

1 is the main body of the mounting bracket of the present invention, and a part of the base side of the main body 1 is extended to form engaging protrusions 2, 2, and the protrusions 2
A through hole is also formed at ゜2 through which the shaft 3 passes.

Reference numeral 3 denotes a shaft, which is provided vertically as shown in FIG. 2, and the main body 1 is fixed by the shaft 3 so that it can swing in the horizontal direction.

A vertical circular hole 17 is bored on the swinging end 6 side of the main body 1,
A vertical shaft 18 is fitted to this for horizontal rotation.

The shaft 18 projects from the circular hole 17 both upward and downward.

An irregularly shaped shaft 16 that has an oval shape when viewed from above is formed on the lower side of the upwardly projecting portion (see section B-B), into which the engagement hole 21 of the mounting plate 22 is fitted.

Since the engagement hole 21 similarly has an oval shape, when the mounting plate 22 rotates horizontally, the shaft 18 rotates.

The upwardly protruding upper part is a cylindrical part 15 as shown in the A-A cross section.
is formed.

A pipe-shaped roller 20 formed of metal fittings, synthetic resin, or the like is fitted into the cylindrical portion 15 .

The mounting plate 22 has a certain length, and has the roller 2 at its swinging end.
The rollers 26 formed in the same manner as 0 are thinned.

The rollers 20 and 26 fit into guide grooves 29 formed in the side wall of the vehicle from below.

The downwardly protruding portion of the shaft 18 is formed into an oval irregular shaft 19 as seen in cross section DD, and a horizontal portion of a supporting metal fitting 23 bent in an L shape is fitted and fixed thereto.

A horizontal shaft 24 is provided on the vertical part of the support fitting 23, and a guide roll 25 is mounted on this shaft.

The direction of the shaft 24 is a direction that crosses the length direction of the mounting plate 22 in a cross shape when viewed from above.

The guide roll 25 abuts on a guide rail 30 formed on the side wall.

In addition, in the figure, I is a pinion carved in the swinging end, 8 is a part of the pinion formed in a wide groove, 9 is an engaging body, 1
0 is a shaft for fixing the engaging body 9 to the main body 1, 11 is a locking pin for stopping rotation of the engaging body 9, 12 is a locking pin implanted in the mounting plate 22, and 13 is an end of the engaging body 9 The engaging pin 12 is engaged with the engaging claw formed in the portion.

Reference numeral 14 denotes a suppressed end portion of the engaging body 9, which projects into the wide groove 8 formed at the most distal end of the pinion 7 while the engaging claw 13 is engaged with the engaging rod pin 12.

Further, 31 is a rack.

Since the present invention has the above-mentioned configuration, its operation will be explained with reference to the plan view of Fig. 3.
7 slides parallel to the vehicle until it reaches the ear position when the door is closed, and when the door is moved further to the left from the ear position and the door is closed, the swinging end of the main body 1 The pinion T formed in the portion 6 and the rack 31 on the vehicle body side mesh with each other, and the main body 1 horizontally rotates as shown by the phantom line.

However, the mounting plate 22 on which the rollers 20 and 26 are mounted
Looking at it, since it is engaged with the linear guide groove 29, it slides to the left without rotating from beginning to end.

That is, when the sliding door 27 is closed, it is the main body 1 that rotates horizontally, and not the mounting plate 22 to which the rollers 20 and 26 are attached.

However, when looking at the guide roll 25 provided below the main body 1 that was developed before this application, the roll 25
Since it was fixed to the horizontally rotating main body 1, its direction changed along with the main body, forcing it to slide.

However, when looking at the guide roll 25 of the present invention, a circular hole 17 is bored in the main body 1, and the support fitting 23 of the guide roll 25 is fixedly attached to the lower part of the shaft 18 fitted in the circular hole 17.
is made to protrude upwards from the main body 1, and the mounting plate 22 is fixed to the protruding part.In the end, in the present invention, only the main body 1 rotates horizontally, and the guide roll 25 remains in the correct position until the door is closed. It maintains the orientation.

In addition, in the case of opening the door, the above order is reversed.

In the conventionally known mounting bracket for a sliding door described in, for example, Japanese Utility Model Publication No. 48-39292, a guide roll was pivoted on a main body having a diamond shape. There was a defect in which the direction of the guide roll changed due to the change in direction, causing the guide roll to become distorted.

In this regard, there are other known examples such as Utility Model Publication No. 48'-22885.
In the mounting bracket described in the publication, the guide roll is attached to the main body that does not rotate, rather than the main body that rotates, so the direction of the guide roll does not change even when the door is closed. , Therefore, the known example has two rollers (
Since it is necessary to adopt a configuration in which the door can be bent freely between the rollers 20 and 26 (corresponding to the rollers 20 and 26 of the present application), there is a risk that the main body holding the door will be shaken.

However, in the present invention, a vertical circular hole 17 is bored in the swinging end side of the main body 1, which is pivoted so as to swing horizontally with respect to the sliding door 27 of the vehicle. axis 1 of
B is rotatably mounted on a shaft, and the shaft 18 projects upwardly and downwardly from the circular hole 17, and the upwardly projecting portion of the shaft 18 is mounted with rollers 20 and 26 on the upper surface of both ends. Board 2
At the same time, one of the rollers 20 and 26 is attached to the shaft 18 in a fixed state, and the support fitting 23 of the guide roll 25, which has the guide roll 25 fixed to the downwardly protruding portion of the shaft 18, is fixed in the fixed state. Since it is attached, the orientation of the guide roll 25 does not change even if the main body 1 horizontally rotates by opening and closing the slide door 27.

Furthermore, since the guide roll 25 and roller 20 are attached to one shaft 18, the structure is simplified.

The rollers 20° 26 are engaged with guide grooves 29 provided on the side wall of the vehicle, and the guide roll 25 is mounted on a guide rail 30 provided on the side wall of the vehicle as a mounting bracket for a vehicle sliding door. , it is possible to prevent the defect that the main body 1 sways while opening the door, as in the above-mentioned known example.
