Abstract

(57) [Abstract] [Purpose] To form a slide mechanism so that the doorway of a car equipped with a slide door on the side of the vehicle body can be opened and closed sufficiently, and the rail part for sliding can be projected to the outside as much as possible. It is intended to be less intrusive and less dangerous. In a slide mechanism in which a door 4 is installed so as to be able to move back and forth through a center rail 3 horizontally provided on a side surface 2 of a vehicle body 1, a rear lower half portion of the door 4 is cut off to form a cutout 5
A center roller 6 that slides along the center rail 3 is provided on the inside 4b of the door 4 near the vertical edge 4a of the door 4 in the cutout portion 5.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sliding mechanism for an automobile door.

[0002]

[Prior Art]

 The conventional sliding mechanism has only one center rail on the side of the vehicle body to support the sliding door when opening and closing, and the center rail also slides on the vehicle body when the door slides. There was a two-stage structure in which the door movement width was increased.

On the other hand, in the former case, since the rail is installed on the side surface of the vehicle body, the length of the rail is restricted, and the rail must be shortened. For this reason, there was a problem that the moving length of the door when the door was opened and slid was insufficient for the width of the entrance / exit, and the entrance / exit opening could not be used sufficiently for entrance / exit.

Further, the latter one has a problem that the structure is complicated, and since the slide mechanism has a two-step structure, the protrusion is excessively projected to the outer side surface of the vehicle body, which may be an obstacle or a danger. there were.

[0005]

[Problems to be solved by the device]

 The present invention configures the slide mechanism so that the door can be slid to the extent that the doorway of the vehicle body can be opened and closed sufficiently, and at the same time, the protrusion of the rail portion is minimized to prevent it from getting in the way and causing danger. It is a device designed to eliminate it.

[0006]

[Means for Solving the Problems]

 The present invention relates to a slide mechanism in which a door 4 is installed so as to be movable back and forth through a center rail 3 provided horizontally on a side surface 2 of a vehicle body 1. In the slide mechanism, a rear lower half portion of the door 4 is cut off to form a cutout portion 5. A center roller 6 that slides along the center rail 3 is provided on the inside 4b of the door 4 near the vertical edge 4a of the door 4 in the cutout portion 5.

[0007]

【Example】

 A lower half portion of the side surface 2 of the vehicle body 1 near the front edge 2a is extended toward the doorway 7 to form an extended portion 2b, and the front edge of the extended portion 2b is curved toward the passenger compartment to form the curved portion 2c. Form. Then, the U-shaped center rail 3 is horizontally fixed between the side surface 2 and the extending portion 2b. On the other hand, the door 4 that opens and closes the doorway 7 is formed by cutting out the lower rear half to form a notch 5, and an arm 8 is provided on the inside 4b of the door 4 near the vertical edge 4a of the door 4 in this notch 5. The bracket 8 is fixed rearward, and a U-shaped bracket 9 is supported on the tip of the arm 8 by a shaft 10 so as to be rotatable in the horizontal direction. Further, a vertical roller 6a and a horizontal roller 6b are attached to a tip 9a of the bracket 9. The shaft is rotatably supported.

The vertical roller 6 a and the horizontal roller 6 b are fitted so as to be able to roll in the center rail 3, and the door 4 is attached to the vehicle body so that the door 4 can move back and forth along the center rail and the side surface 2. . Upper and lower rails 11 and 12 are horizontally provided at the upper and lower edges of the doorway 7 of the vehicle body 1, and an upper roller 13 and a lower roller 14 for rolling the upper and lower rails 11 and 12 are installed on the door 4 of the door 4. It is attached to the upper and lower corners near the front edge of.

[0009]

[Effect of the device]

 According to the present invention, as described above, the extension portion is formed in the front lower half portion of the side surface of the vehicle body, the center rail is provided on the side surface and the extension portion, and the rear lower half portion of the door is cut off corresponding to the extension portion. However, since the vertical and horizontal rollers that roll in the center rail were installed on the vertical edges of the cutouts, these rollers were installed at a position closer to the front than when they were installed at the rear edge of the conventional door. Therefore, it is not necessary to lengthen one center rail so that the door can be fully retracted so that the entrance and exit are sufficiently open, and unlike the center rail with a double structure, it protrudes outward and interferes. The entrance and exit can be fully opened and the structure is simple.
