Description

[Detailed description of the invention] [Purpose of the invention] "Industrial application field" This invention relates to a draw and pull mechanism for sliding windows. In particular, the present invention relates to a draw and pull mechanism suitable for terrace windows with large openings in the vertical direction.

``Prior Art'' Conventionally, as a drawing and pulling mechanism for sliding windows, a tightening handle device with a latch, for example, a crescent, is provided at one location near the vertical center of the connecting stile of the inner shoji, and the crescent and the outer shoji are pulled together. By engaging the receivers, the cylindrical cam part of the crescent pulls the inner and outer shoji together, and the end cam part of the crescent draws the sliding shoji apart and presses it against the left and right vertical frames. The smoke return engages and pulls the comrades together in general. In conjunction with this operation of the tightening handle device, the tightening handle drives a pulling tool at the upper and lower ends of a vertically movable member such as a slide bar that is movable in the longitudinal direction of the connecting stile of the inner shoji. The inner shoji is pulled toward the window frame by engaging the puller with the upper and lower frames. The outer shoji is connected by the inner shoji with a crescent and a smoke return and is drawn together. Airtightness is achieved by compressing the sealing material placed on the opposing surfaces of the joining frames of the inner and outer shoji and the sealing material between the vertical stile and frame of the inner and outer shoji.

``Problem that the invention aims to solve'' In the conventional example described above, the inner and outer shoji are drawn at the center of the stile and a concentrated load is applied, so the engagement of the chimney return is not possible due to deflection at the top and bottom of the stile. As a result, the sealing material placed between the inner and outer frames of the inner and outer shoji shoji cannot be compressed at the top and bottom of the stile, resulting in a gap between the inner and outer shoji.

For this reason, if you increase the amount by which the sashes of the inner and outer shoji are drawn, the force to operate the tightening handle will increase, putting stress on the drawing and pulling device and damaging it, so this is not allowed in terms of handling. Ru.

Also, there are some that are equipped with a device that only pulls between the position of the tightening handle in the center of the binding stile and the top and bottom ends of the binding stile, but since it is only a pulling mechanism, it tends to occur in the pulling direction. This was not sufficient to eliminate the gap between the top and bottom of the connecting frame due to deflection.

This design allows the connecting frames of the inner and outer shoji to be drawn evenly in the inner and outer directions, and the connecting frames are evenly pressurized in the drawing direction over their entire length, so that each connecting frame does not sag. The purpose of the present invention is to provide a drawing and pulling mechanism for sliding sliding shoji doors that can be equally approached.

[Structure of the idea]

``Means for Solving the Problems'' This invention is based on a tightening handle device installed in the center of the sliding frame of a sliding window and a puller device that engages with the window frame at the upper and lower ends of the sliding window. This is a drawing/pulling device for a sliding window, each of which is provided with a drawing/pulling mechanism driven by the closing handle device.

"Operation" When the tightening handle device is activated, the inner and outer shoji are drawn and pulled together by the pulling and pulling means provided directly in the tightening handle device, and the pulling device that works in conjunction with the tightening handle device operates to move the upper and lower portions of the inner shoji to the window frame. The outer shoji drawn to the inner shoji is pulled by the pulling means of the smoke return and tightening handle part, and the inner and outer shoji are further pulled by the pulling mechanism between the tightening handle device and the pulling tool. The inner and outer shoji are drawn and drawn at three points, and the inner and outer shoji are drawn at the top and bottom to the window frame.

"Example" Hereinafter, an example of this invention will be described with reference to the drawings. FIG. 1 is a front view of the sliding window seen from the inside.

An inner shoji 2 and an outer shoji 3 are fitted into the opening frame 1 in a sliding manner. Although detailed explanation is omitted, a known tightening handle device 5 is attached to the left end surface of the central part of the connecting stile 4 of the inner shoji 2. The tightening handle device 5 engages, for example, a crescent as a latch with a receiver attached to the connecting stile of the outer shoji 3 by rotating an operating handle 6 that can be rotated around an axis that is horizontal and parallel to the wall surface. At the same time, the central parts of the inner and outer shoji are drawn and pulled together, and the interlocking means actuates the pulling tools 7, 7 provided at the top and bottom of the matching stile 4 of the inner shoji to pull the matching stile 4 of the inner shoji 2 to the opening frame 1. At the same time, the outer shoji 3 is drawn inward by the crescent and the chimney return provided on the opposing surfaces of the joining frames of the inner and outer shoji 2, 3.

[Effect of idea]

This invention consists of a tightening handle device provided at the center of the sliding frame of the sliding window, and a puller driven by the tightening handle device located between the puller which engages with the window frame at the upper and lower ends of the sliding window. Since the device for sliding windows is equipped with a separating and pulling mechanism, the inner and outer shoji are pulled in three places: the center, the middle of the upper and lower ends, and the center. As a result, the inner and outer shoji are evenly drawn together, and the sealing material on the joining stile is pressed evenly and works effectively without the joining stile being bent by the drawing force. In addition, since the inner and outer shoji are equally drawn, the drawing force acts equally on the inner and outer shoji, and the inner and outer shoji are closely pressed against the opening frame.
