DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roller mounting device for mounting a roller for supporting a door body so as to be able to travel on a fixed object such as a gate wall.

[0002]

2. Description of the Related Art As an example in which a conventional roller mounting device is provided, there is a horizontal sliding door shown in FIG.

[0003] In the figures, reference numerals 1 and 2 denote gate walls which are erected so as to sandwich an entrance 3.
2 and the rail 4 is laid on the ground.
The door body 6 is on the rail via the traveling wheel 5. Doorway 3
The door 6 is moved along the rail 4 by pushing or pulling the door 6.

[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 gate 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 at least four sets of rollers on the upper, lower, left and right sides of the gate wall, and the door body is supported by the rollers so that the door can run freely.

[0006]

In the above-mentioned non-rail type horizontal sliding gate door, the positional relationship between the door and the roller is delicate. If the distance between the upper and lower rollers is too large compared to the height of the door, the leading end of the door when the door is pulled out. He bows and may get out of the wheel. Conversely, when the interval between the upper and lower rollers is small, the operating force for opening and closing increases. In addition, if the left and right lower rollers are not mounted horizontally, if the door is pulled out to the roller that is lowered, bow and if you try to move the door to the roller on the upper side, the operating force will be large. Become. Therefore, the mounting positions of the upper, lower, left and right rollers greatly affect the operability of opening and closing the door body, and mounting requires accuracy. However, as the scale of the horizontal sliding gate increases, the mounting position accuracy of the rollers becomes difficult, and there is a problem that it takes a long time to install the non-rail type horizontal sliding gate.

The present invention has been made in view of the above circumstances, and has been made to make it possible to easily adjust the position of a roller and to improve workability when a non-rail type horizontal sliding door is installed.

[0008]

According to the present invention, an upper block is fixed to a base plate attached to a fixed object, a substrate is fixed to the base plate via fixing bolts, and a lower block is fixed to the substrate. A hanging bolt for inserting the upper block is screwed to the lower block, a tip of a push bolt for screwing the upper block is brought into contact with the lower block, and an attachment hole through which the fixing bolt is inserted is an elongated hole, According to a roller mounting device in which a roller is supported on the substrate, the suspension is turned on the substrate while temporarily fixing the substrate to a base plate to adjust the distance between the upper block and the lower block, thereby mounting the substrate on the substrate. The position of the upper roller is adjusted, and when the position adjustment is completed, the substrate is finally fixed to the base plate via the fixing bolt.

Embodiments of the present invention will be described below with reference to the drawings.

First, referring to FIG. 3, a description will be given of a non-rail type horizontal sliding door in which the roller mounting device according to the present invention is implemented.

On the upper part of the gate wall 2, two sets of upper rollers 10, 10
Are provided rotatably, and two sets of lower rollers 11, 11 are rotatably provided below the gate wall 2. Lower roller 1
A brake (not shown) is provided inside one of the lower roller 11 and the lower roller 11, and the lower rollers 11, 11 are connected by a chain 19 so that the lower rollers 11, 11 rotate integrally. ing.

The door body 12 is held between the upper rollers 10 and 10 and the lower rollers 11 and 11 so as to be able to travel 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 rollers 10 and 10 rollably contact the upper guide rail 13,
Lower rollers 11, 11 are in rolling contact with the lower guide rail 14. A door receiving stand 15 is fixed to the gate wall 1, and 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.

A lower part of the door body 12 is provided with a braking control mechanism 17 over its entire length, and a required front end of the door body 12 is provided with a braking operation lever 18 at a required height. The braking control mechanism 17 is connected to the braking control mechanism 17 by a required connecting means such as a wire. By operating the braking operation lever 18, a brake inscribed in the lower roller 11 can be operated via the braking control mechanism 17.

An embodiment of the present invention applied to the upper roller 10 shown in FIG. 3 will be described with reference to FIGS.

A base plate 20 is fixed to the gate wall 2 with bolts 21, and fixing bolts 22 are erected on the base plate 20. An upper block 23 is fixed to the upper end of the base plate 20, and a through hole 24 penetrating vertically is formed in the upper block 23 at the center, and screw holes penetrating vertically on both sides of the through hole 24. 25
Drilling.

A substrate 27 is fixed to the base plate 20.
The mounting holes 2 through which the fixing bolts 22 pass are formed in the substrate 27.
8 is formed, and the mounting hole 28 is a vertically long hole. A lower block 30 facing the upper block 23 is fixed to the upper end of the substrate 27.
, A screw hole 31 is formed on the axial extension of the through hole 24.

A roller shaft 33 is erected on the substrate 27, the upper roller 10 is rotatably mounted on the roller shaft 33, and a bearing bracket 34 is fitted to a tip of the roller shaft 33, A side bracket 35 is fixed to the bearing bracket 34 by bolts (not shown). By fixing the substrate 27 and the bearing bracket 34 by the side bracket 35, both ends of the roller shaft 33 are supported, and the upper roller 10, the substrate 27, and the bearing bracket 34 are integrated, and the support mechanism of the upper roller 10 is unitized. Is done.

The fixing bolt 22 is inserted through the mounting hole 28, and a nut 36 is screwed to the fixing bolt 22, and the upper roller 10 is fixed to the base plate 20 via the substrate 27.

A suspension bolt 37 is inserted into the through hole 24 and screwed into the screw hole 31, and the tip of the push bolt 38 threaded through the screw hole 25 is brought into contact with the upper surface of the lower block 30. With the nut 36 slightly loosened, the suspension bolt 37 is tightened and loosely returned, and the push bolt 38 is pushed in and retracted, so that the upper block 23 and the lower block 30 are moved.
, That is, the vertical position of the roller 10 via the substrate 27 can be adjusted.

The hanging bolt 37 and the push bolt 38
Accordingly, a desired amount of displacement can be reliably given to the substrate 27, and the fine vertical position of the substrate 27, that is, the vertical position of the upper roller 10 can be adjusted. When the final position of the upper roller 10 is determined, the nut 36 is tightened to fix the substrate 27 to the base plate 20. Further, the adjustment can be performed even in a state where the door body is incorporated, and the troublesome work of removing the door body every time readjustment is performed is omitted.

[0021]

As described above, according to the present invention, the upper block is fixed to the base plate attached to the fixed object, the substrate is fixed to the base plate via fixing bolts, and the lower block is fixed to the substrate. Then, a suspension bolt for inserting the upper block is screwed to the lower block, a tip of a push bolt for screwing the upper block is brought into contact with the lower block, and a mounting hole through which the fixing bolt is inserted is elongated. Since the roller is supported by the substrate, the position of the roller can be adjusted by the hanging bolt and the push bolt, and a desired displacement can be surely realized and the workability is significantly improved.
