Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a device for attaching a door roller to a shoji of a sliding window.

Prior Art As shown in Japanese Patent Publication No. 51-35788, a housing is fixed to the lower stile of a shoji screen, the axle of a door roller is attached to this housing so as to be movable up and down, and a pin of a connecting rod fixed to this axle is attached to the housing. By fitting into the formed horizontal hole and moving the pin along the horizontal hole, the connecting rod is lowered and raised, and the axle is moved up and down, allowing the door roller to be moved up and down relative to the lower stile. At the same time, the door roller mounting device is configured to lower and raise the connecting rod by the force of collision with the door stop and the rotational force of the door roller.

As shown in Japanese Unexamined Patent Publication No. 59-55974, a door roller is attached to a link that is pivoted to the lower stile, and this link is connected to an operating lever provided on the shoji, and the link is activated by rotating the operating lever. A door roller mounting device that bends upward and downward so that the door roller can be moved up and down relative to the lower stile.

Problems that the invention aims to solve: With the former mounting device, the axle and pin are in a vertical position and the door roller is moved downward, so the upward force acting on the door roller is due to the fit between the pin and the horizontal hole. As the shoji is held in place, its holding becomes unstable, and when the shoji is opened and closed, the door roller may move upwards, making it impossible to open and close the shoji smoothly.In addition, the connecting rod may be moved from a reclining position to an upright position. Since this uses the rotation of the door roller, the door roller must always be in contact with the rail of the lower frame, and it is not possible to make the door roller float above the rail by directly touching the lower stile to the lower frame.

With the latter device, the door roller is held in a downward position by links, so the holding force is weakened and the door roller moves upwards when opening and closing the shoji, making it impossible to open and close the shoji smoothly.

Means and operation for solving the problem A mounting body is attached to the lower stile of the shoji, and a door roller mount including a support member and a door roller is attached along the lower stile and is in contact with the stepped lower surface of the mounting body. The door roller mounting body and the vertical sliding rod provided on the vertical stile are connected by a link, and the lower part of this vertical sliding rod and the hole in the block provided in the lower frame of the window frame are mutually connected. By forming a slope that pushes the shoji toward the closing side in contact with the support member and touching the high and low parts of the mounting body, the door roller can be moved up and down relatively, and the load of the shoji is transferred to the bottom surface of the mounting body. The shoji can be supported at the abutting portion between the shoji and the support member, and by fitting the vertical sliding rod into the hole in the block, the shoji can be pushed toward the closing side and airtightness can be improved.
