Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door structure for closing an opening in a freezing room of a freezing vehicle or a living room or a luggage room of a one-box type vehicle.

[0002]

2. Description of the Related Art Conventionally, in vehicles having relatively flat outer walls, such as refrigerated vehicles, container vehicles, and one-box vehicles, rolling on flat rails substantially parallel to the outer walls of luggage compartments such as freezer compartments or living rooms. The sliding door is slid by the moving guide roller to close the opening of the chamber. The sliding doors used in these vehicles are broadly classified into rail type, link type and sliding door type. The one shown in FIG. 3A is called a rail type, and has an upper rail having a guide portion curved inward at a slide end position.
By three rails of center rail and lower rail,
The movement of the slide door is regulated and controlled via guide rollers axially supported at the front and bottom of the slide door and the center of the rear part, so that the slide door is pressed against the outer wall of the room when the slide door is closed. The one shown in FIG. 3 (B) is called a link type, in which two upper rails and two lower rails are provided, and each has two links with rollers that roll in each rail. The slide door is pressed against the outer wall of the chamber by a lock shaft rotated by a lever at the slide end position of the slide door. The one shown in FIG. 3 (C) is a so-called sliding door type, which is a simple type in which a sliding door which is guided by an upper rail and a lower rail and axially supports a guide roller slides parallel to the outer wall of the room. is there.

FIG. 4 shows the structure of FIG.
A typical example of the rail type shown in (A) is disclosed in Japanese Utility Model Publication No. 61-12254, which is adopted for a one-box type vehicle. In this example, a substantially U-shaped guide rail 3 is provided coaxially with a running roller 30 which receives a vertical load.
5, a thrust ball 32 which is in contact with the vertical surface 35b is attached, and the guide roller 34 is spaced apart from the traveling roller 30 in the front-rear direction and is positioned above the traveling roller 30.
The guide roller 34 is brought into contact with the left and right sides 35c and 35e of the guide rail 35 so that the displacement (play) of the traveling roller 30 in the left and right direction can be almost completely regulated.

[0004]

However, in these conventional vehicle structures, in the rail type shown in FIGS. 3A and 4, when the slide door is closed by the rail itself, the outer wall of the room is closed. Control is required so that the rail structure is complicated. In addition, three rails are required, which increases the number of parts and increases the cost. In addition, when the door is opened, the sliding door extends to the side of the vehicle body. In addition to increasing the volume, the interior volume was reduced. In the case of the link type shown in FIG. 3B, the number of rails is so large that smooth movement cannot be expected. Further, after the slide is completed, the link with rollers is swung to press the slide door against the outer wall of the room. In addition to being unsuitable for quick door lock with one touch, the interior volume is reduced by the thickness required for installing the lock handle. Further, the sliding door type shown in FIG. 3 (C) has a simple structure provided with flat rails that are substantially parallel to the outer wall of the room, and compensates for the drawbacks of the above two types. Inferior, there was a risk that dust and rainwater would enter the room.

In view of the above, the present invention solves the above-mentioned problems of the conventional slide door structure, and can secure a reliable sealing even with a simple structure, and can maintain a hygienic room at low cost. The purpose is to provide.
