FIG. 4 shows a state where the door roller A and the door guide B of the present invention shown in FIGS.
By adjusting the door roller A and the door guide B, the mounting state of such a sliding door can be easily adjusted. When adjusting the position of the sliding door 100 in the height direction, that is, the Z direction, the screw member 5 of the door roller A is rotated. For example, when lowering the height of the sliding door 100, the screw member 5 is rotated, for example, clockwise. As a result, the pin 6 is
2 and travels from left to right in FIG. Since the pin 6 is fitted in the groove 45 of the inner frame 4, even if the screw member 5 is rotated, the pin 6 moves forward and backward without rotating together with the screw member 5. As a result, the pin 6 further falls into the groove 45, and the inner frame 4 rotates clockwise about the support shaft 35, so that the distance between the mounting hole 11 of the outer frame 1 and the wheel 2 is shortened, and accordingly, The position of the sliding door 100 is lowered. When raising the height of the sliding door 100, by turning the screw member 5 counterclockwise, an operation completely opposite to the above occurs, and the height of the sliding door 100 can be raised.

When adjusting the position of the sliding door 100 in the thickness direction, that is, the Y direction, the eccentric ring 7 is rotated, and the eccentric disk portion 71 is pressed against either the side plate 33 or 34 of the intermediate frame 3 to support it. The intermediate frame 3 is rotated around the shaft 14, the set screw 8 is tightened, and the rotated position is fixed via the support shaft 35. As a result, as shown by a two-dot chain line in FIG. 1A, the wheel 2 can be moved by the distance s in the Y direction via the rotation of the inner frame 4. However, since the wheel 2 is fitted in the rail 101 and its Y-direction position does not change, the mounting hole 11 of the outer frame 1 moves by the distance s in the direction opposite to the direction in which the wheel 2 moves. As a result, the sliding door 100 fixed to the mounting hole 11 moves by the distance s in the thickness direction. The rotation of the inner frame 4 accompanying the rotation of the intermediate frame 3 is smoothly performed by centering on the portion of the groove 45 in contact with the pin 6.

The position of the sliding door in the Y direction by the door guide B is adjusted by rotating the eccentric ring 7 '.
Can be performed in exactly the same way as the adjustment. By adjusting only the door roller A, the upper end portion of the sliding door 100 does not move, and only the lower end portion moves by the distance s. However, if the door guide B is adjusted by the same distance in the same direction, the sliding door 100 is moved up and down by the upper and lower rails 101. Can be moved by a distance s in parallel with However, the direction of adjustment and the adjustment distance, such as adjusting only one of the door roller A and the door guide B or adjusting each of them in directions opposite to each other, are appropriately adjusted according to the actual state of the sliding door to which the door is attached. Will be

If the present invention is applied to the upper and lower door rollers and door guides as shown in FIG. 4, various adjustments can be made as described above, which is extremely convenient. However, depending on the type and size of the door to which these are mounted, the installation accuracy, and the like, it is also possible to use a conventional structure on any one side. FIG. 4 shows an example of the sliding door in which the door A is attached to the lower end and the door guide B is attached to the upper end. However, the door and the door guide of the present invention can be applied to a hanging door and the like.
In the case of a hanging door, the door A is on the top and the door guide B is on the bottom.

[0020]

As described above, according to the present invention, according to the first aspect of the present invention, in addition to the main body and the wheels attached to the door, an intermediate support, a wheel support, a screw member, an engaging member, and a rotating member are provided. Is provided, and these are connected in association with each other, so that the position adjustment in the thickness direction in addition to the vertical direction of the door can be performed extremely easily. That is, by engaging the screw member and the engaging member, and further engaging the engaging member and the wheel support, only by operating the screw member, the engaging member is moved in the X direction in which the wheel is guided. The wheel support is rotated in the direction of the door surface with this movement, and the height position of the wheel fixed to the wheel support can be moved in the vertical direction. As a result, the vertical position of the door can be adjusted.

On the other hand, such a vertical adjustment mechanism is supported by an intermediate support supported by the main body, and the intermediate support is similarly rotatable by operating a rotating member supported by the main body. Therefore, the rotation of the intermediate support causes the wheel support to move in the Y direction, which is perpendicular to the X direction. As a result, the door can be moved in the Y direction via wheels whose position in the Y direction is restricted by rails or the like. Therefore, the position in the thickness direction of the door can be easily adjusted only by operating the rotating member.

According to the second aspect of the present invention, the position of the door in the thickness direction can be adjusted by operating the rotating member in exactly the same manner as described above. As a result, claim 2 together with the door roller according to claim 1 of the present invention
By mounting the door guide of the present invention on the door, it is possible to make an adjustment such that the door is moved in parallel in the thickness direction.
