Description

[Detailed Description of the Invention] The present invention relates to an automobile sliding door holding device that has a low failure rate and can be opened and closed extremely easily.

Conventional holding devices have a roller that receives the weight of the sliding door and a roller that receives the thrust load, which are placed separately on a groove rail provided on the car body or a protruding rail installed on the outer panel of the car body, and a roller that receives the thrust load. Mizouchi was able to transfer jobs.

In addition, a gap must be provided between the roller and the rail so that the roller can easily roll.

For this reason, when the sliding door is opened and closed, the sliding door moves up and down, and the roller that receives the thrust load slams into the top of the groove, causing the ball bearings and spindles that support the roller to be bent or damaged. This often caused malfunctions and made it extremely difficult to open and close the sliding door.

Therefore, in the present invention, sliding members with a low coefficient of friction made of plate-like materials such as resin, oil-impregnated resin, oil-impregnated alloy, etc. are attached to the left and right side walls of the guide groove provided at the top of the groove rail, and the slide door facing the groove rail is installed. By erecting a sliding member that slides in the guide groove from the inner surface of the slide door, even if the sliding member moves vertically and collides with the top of the groove rail when the sliding door is opened or closed, This eliminates the drawbacks of the prior art by preventing the sliding member from being damaged and causing malfunction.

Next, an embodiment of the present invention will be explained with reference to the drawings.
A door opening 4 that is open from the floor 2 to the roof 3 is formed on one side of the door.

At the lower edge of the door opening, a guide groove 5 that opens vertically downward is provided at the top, and a guide surface 6 facing the guide groove 5 is provided at the bottom. It is arranged to be approximately the same width as the opening.

Further, a guide groove 8 that opens vertically downward is provided at the upper edge of the door opening so as to be approximately the same width as the door opening.

On the other hand, an arm 10 is horizontally extended at the upper part of the rear end of the slide door 9 that covers the door opening 4 in the opening direction of the slide door, and a roller 11 is pivotably supported at the tip of the arm 10 so as to be rotatable vertically upward. The roller is fitted in the guide groove 8 on the upper edge in a movable manner.

A bracket 12 is horizontally extended at the lower part of the rear end in the opening direction inside the sliding door 9, and a roller 1 is attached to the tip of the bracket 12.
3 is rotatably supported vertically upward, and the roller is rotatably fitted into a guide groove 5 in the groove rail I on the lower edge, and is also fitted inside the slide door 9 below the bracket. An arm 14 extends horizontally, and a roller 15 is horizontally supported at the tip of the arm 14 and is disposed to roll on the guide surface 6 in the groove rail I.

On the other hand, a guide groove 17 that opens vertically downward is provided in the upper part of the vehicle body outer panel 16 in front of the sliding door 9 in the opening direction at a position corresponding to the vertical center of the sliding door.
The left and right side walls of the guide groove are made of resin with a small friction coefficient or
Sliding members 18a, 1 made of oil-impregnated resin or oil-impregnated alloy, etc.
8b, and a groove rail 20 having a guide surface 19 facing the groove rail 20 at its lower part extends horizontally.

Further, a fulcrum seat 21 is provided at the front end of the slide door 9 inside the slide door 9 at a position facing the groove rail 20 in the opening direction of the slide door.
is attached to which a shaft 22 is attached to the fulcrum seat 21.
A roller 23 that rolls on the guide surface 19 is rotatably attached to the shaft, and a roller 23 that rolls on the guide surface 19 is rotatably mounted on the shaft. A sliding member 25 having a drum-shaped cross section and sliding in the guide groove 17 is erected at the tip of the extended arm 24 near the roller 23 .

1. When the sliding door 9 is opened and closed, the rollers 23 roll on the guide surface 19 in the groove rail 20 while receiving the weight of the sliding door, and the sliding member 25 rolls on the guide surface 19 in the groove rail 20.
The slide door slides in the inner guide groove 17 while receiving a load in the width direction of the vehicle body.

In this embodiment, the groove rail 20 is a straight line as shown in FIG. 4, but the groove rail 20 is not limited to this, and may be a curved line.

Further, in this embodiment, the holding device is configured to slide within a groove rail on the outer panel of the vehicle body in front of the sliding door in the opening direction. You may also use it.

As described above, according to the present invention, sliding members with a small friction coefficient are attached to the left and right side walls of the guide groove provided on the upper part of the groove rail, and the inside of the guide groove is slid from the inner surface of the sliding door facing the groove rail. Since the sliding member is installed vertically, the sliding member will not be damaged even if the sliding door jumps up and down when the sliding door is opened and closed and the sliding member hits the top of the guide groove. This not only dramatically reduces the failure rate, but also allows the sliding door to be opened and closed easily at all times.

Further, since the rail is a grooved rail, the grooved rail is not easily damaged even in the event of a vehicle accident, and therefore, it is extremely easy for the occupant to escape from the vehicle, and the safety is high, and its effects are great.
