DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal sliding door, and more particularly to a non-rail type horizontal sliding gate door falling prevention device.

[0002]

2. Description of the Related Art FIG. 4 shows a conventional horizontal sliding door.

[0003] In the figures, reference numerals 1 and 2 denote gate walls which stand up and down an entrance 3, cross the entrance 3 and extend between the gate walls 1 and 2, and a rail 4 is laid on the ground. A door 6 is mounted on the vehicle 4 via a traveling wheel 5. The door 3 was moved along the rail 4 by pushing or pulling the door 6 to open and close the doorway 3.

[0004] Opening and closing of a horizontal sliding door having a rail 4 laid on the ground depends on the state of the ground. For example, if there is snow and the rail 4 is buried in the snow, the door 6 cannot move. Therefore, a non-rail type horizontal sliding door has been proposed as a horizontal sliding gate that can be opened and closed with a small force without being affected by the state of the ground.

[0005] The non-rail type horizontal sliding gate door is provided with a roller for supporting the door body on the gate wall, and the door body is movably supported by the roller.

On the upper part of the gate wall 2, two upper roller units 1
0, 10 are provided, and two lower roller units 11, 11 are provided below.

The door 12 is provided with the upper roller units 10, 1
0 and the lower roller units 11, 11 so that they can run freely. An upper guide rail 13 is fixed to an upper end surface of the door body 12, and a lower guide rail 14 is fixed to a lower end surface.
The upper roller rails 10 and 10 are attached to the upper guide rail 13.
The lower roller units 11, 11 are in rolling contact with the lower guide rail 14.

A door receiving stand 15 is fixed to the gate wall 1 so that the front end of the door 12 comes into contact with the door in a closed state. A stopper 16 is provided behind the gate wall 2, and the stopper 16 holds the door body 12 in an open state. Incidentally, reference numeral 17 in the drawing denotes a handle for opening and closing the door.

The non-rail type horizontal sliding door has an excellent effect that the door body can be opened and closed with a small running resistance and a small force and can be opened and closed regardless of the road surface condition.

[0010]

In the rail type horizontal sliding gate described above, since the door itself can stand alone, it is not particularly necessary to prevent the door from falling down. The sliding door can be opened and closed with a small force, but since the door body is sandwiched between the upper and lower upper roller units 10, 10 and the lower roller units 11, 11, the door body may be disengaged from the roller unit. Sometimes the body falls down.

In view of such circumstances, the present invention is intended to prevent the door from coming off the roller unit, especially in a non-rail type horizontal sliding door, and to prevent the door from falling over even when it comes off. .

[0012]

According to the present invention, an upper row is mounted on a gate wall.
La unit, the lower roller unit provided, travels freely holding said upper roller unit, the door between the lower roller unit,
The present invention relates to a door pulling prevention device for a horizontal pulling gate provided with a tilting prevention bar extending between the upper roller unit and the lower roller unit. In addition, the door body is prevented from falling when the door body comes off.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

1 and 2, the same components as those shown in FIG. 3 are denoted by the same reference numerals.

On the upper part of the gate wall 2, two sets of upper roller units 1
0, 10 are provided, and two lower roller units 11, 11 are provided below.

The door body 12 is provided with the upper roller units 10, 1
0 and the lower roller units 11, 11 so that they can run freely. An upper guide rail 13 is fixed to an upper end surface of the door body 12, and a lower guide rail 14 is fixed to a lower end surface.
The upper roller rails 10 and 10 are attached to the upper guide rail 13.
The lower roller units 11, 11 are in rolling contact with the lower guide rail 14.

In FIG. 1, between the upper roller unit 10 and the lower roller unit 11 on the left side and the upper roller unit 1 on the right side.
Bar 2 between the lower roller unit 11 and the lower roller unit 11
0 and 20 are provided respectively.

By connecting the upper roller unit 10 and the lower roller unit 11 with a fall prevention bar 20, the load acting on the lower roller unit 11 is transmitted to the upper roller unit 10, and the load can be dispersed. For this reason, the amount of deflection on the lower roller unit 11 side is reduced, the opening between the upper roller unit 10 and the lower roller unit 11 is reduced, and the door 12 is less likely to come off from the upper roller unit 10 and the lower roller unit 11. Furthermore, even if the door body 12 comes off from the upper roller unit 10 and the lower roller unit 11, the door body 12 does not fall because the fall prevention bar 20 is provided.

In order to further improve the appearance, a door pocket or a cover for accommodating the door body 12 when the door body 12 is opened may be provided. In this case, the fall prevention bar 20 also serves as a mounting frame. Can be.

[0020]

As described above, according to the present invention, in a non-rail type horizontal sliding door, the door can be prevented from tipping over and the safety can be improved. In addition, the load acting on the lower roller unit can be dispersed, and excellent effects such as reduction of the load on the lower roller unit can be exhibited.
