DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adjustable door pulley for closing a gap formed between a lower edge of a shoji and a rail, and a gap closing device for the lower edge of a shoji.

[0002]

2. Description of the Related Art Conventionally, indoor sliding doors have often been built into grooves formed in a sill and a sill, and sliding doors have been slid along the grooves. Advances in decorative technology and the like have led to the use of aluminum shoji for interior fittings. Since this aluminum shoji has a certain weight, it is common to provide a door roller on the lower surface of the shoji and move the shoji along a groove rail buried and installed on the floor side.

[0003] On the other hand, so-called adjustable door rollers have been used in the above-mentioned door rollers, in which a sliding door can be adjusted in a vertical direction in order to adjust the installation. Various structures have been proposed as the structure of the adjusting door wheel.
For example, the vertical adjustment structure shown in FIG.
0 is held by a holding frame 53 composed of an inner frame 51 and an outer frame 52, and a vertical adjustment screw 54 provided in a penetrating state from the outer frame 52 is screwed to the inner frame 51. By turning the adjustment screw 54 to slide the inner frame 51 in the rail direction, the door or the shoji can be adjusted vertically. Specifically, an oblique groove 51 for holding the roller shaft 50a of the roller 50 in the inner frame 51 is provided.
a, a vertical groove 52a for holding the roller shaft 50a is formed in the outer frame 52, and the outer frame 52 is fitted in a state where the roller 50 is mounted on the inner frame 51. , 52a hold the roller shaft 50a, and turn the vertical adjustment screw 54 to slide the inner frame 51 in the rail direction. As a result, the roller 50 is guided by the oblique grooves 51a of the inner frame 51. Are moved in the vertical direction, and the sliding door or the entire door is relatively moved and adjusted in the vertical direction.

[0004]

However, in the case of a shoji provided with the above-mentioned adjustable sliding door which can be adjusted up and down, it is necessary to provide at least a gap P for the adjustment between the shoji and the rail. When the door is closed, a gap is formed at the lower edge of the shoji, causing problems such as leakage of lighting in the adjacent room or intrusion of cold air staying on the floor surface of the adjacent room. In this case, it is still a problem that the gap closing plate is newly attached to the sash because the gap is formed in the same manner by adjusting the vertical position of the sash, or it cannot be adjusted downward by contact with the rail. Is not resolved.

In order to cope with such a problem, Japanese Utility Model Laid-Open No. 3-95488 discloses a device in which a sliding member capable of moving up and down is provided on the lower edge side of a sliding door. However, this gap prevention device moves the gap prevention member up and down by operating the handle after closing the sliding door, and the mechanism for that is very complicated, and the handle operation must be performed each time the sliding door is opened and closed. There is a problem that must be.

SUMMARY OF THE INVENTION Accordingly, a main object of the present invention is to provide an adjustment door wheel having a vertical adjustment function capable of securely closing a gap between a lower edge of a sash and a rail formed when a sash is built, irrespective of the vertical adjustment of the sash. Another object of the present invention is to provide a device for preventing a gap at a lower edge of a shoji.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to an adjusting door roller having at least a vertical adjusting function, wherein a roller shaft rotatably supporting a door roller is used as a supporting member, and a sliding door is provided. A door-roller gap closing member for closing a gap formed between the lower edge of the sash and the rail at the location of the adjusting door wheel at the time of installation is provided.

[0008] Further, in the device for preventing a gap at the lower edge of a shoji using the adjusting door wheel, the adjusting door wheel is disposed at both ends of the sliding door, and the adjusting door wheel is straddled between the door wheel gap closing members. An intermediate gap closing member for closing a gap formed between the sash and the rail along the lower edge of the sash is transversely mounted. In other words, it is a separate type of the door wheel gap closing member and the intermediate gap closing member.

The second device for closing a gap at the lower edge of a shoji has at least a pair of adjustment door rollers having an up-down direction adjustment function, with respective roller shafts rotatably supporting door rollers serving as support members. A gap closing member is provided substantially over the entire length of the lower edge of the shoji to close the gap formed between the lower edge of the shoji and the rail when the shoji is built. A clearance closing member is integrated with the first clearance prevention device.

In the present invention, the roller closing shaft is rotatably supported by the roller shaft, and the gap closing member is attached to the roller shaft. Therefore, even if the vertical position is adjusted and the vertical position of the shoji is changed, the relative positional relationship between the gap closing member and the door roller does not always change. In addition, the gap formed in the lower edge of the shoji screen can be effectively closed.
