Description

[Detailed Description of the Invention] Technical Field This invention provides a soundproofing sash pulling device that improves airtightness by drawing the combined parts of soundproofing sashes, such as double-sliding, four-sliding, single-sliding, etc., toward the indoor side. It is related to.

PRIOR ART AND THE PROBLEMS Conventionally, this type of pulling device has been designed to attach a pulling block to a box, and to raise and lower a pulling block that is raised and lowered by the rotation of the pulling handle. A system has been put into practical use in which the sliding block is freely provided and engaged with the window frame to draw the outer shoji sliding stile to the indoor side and the inner shoji sliding stile to the indoor side. However, with the above-mentioned pulling device, although there is an advantage that the outer shoji-drawing stile can push the inner shoji-drawing stile toward the indoor side and reliably pull the ryōri stile together, Because it is installed on the stile, it is difficult for ordinary people who are accustomed to operating the crescents of general sashes (which are pivoted to the inner and outer sashes) to operate the sashes, and the inner and outer sashes are completely different. In order to do this, the expected width of the outer shoji had to be made thicker, which caused the problem that it was not suitable for the complete sliding soundproofing sash of general windows.Therefore, in order to solve the above problem, we developed Utility Model Publication No. 57 50466. As shown in the publication, Gremon handles 1 to 1 are pivotally attached to the inner shoji frame, and a receiving metal fitting is rotatably pivoted to the outer shoji frame and biased in one direction. By rotating the handle, the above-mentioned frame rotates the metal fitting against the biasing force, and by rotating the receiving metal fitting, a pulling member provided at the end of the outer shoji-gathering frame is actuated, and the outer shoji-gathering frame is moved. A device that pulls the stile toward the indoor side has been proposed, but in this device, the return operation of the receiving metal fittings and pulling member is performed by a spring, so when the stile is released, The reality is that it has not been put into practical use because of the fatal problem of the unreliability of the return operation of the outer shoji folding frame3.
As shown in Japanese Patent No. 4'5323, a rotating body that can be rotated indoors and outdoors by a vertical axis is provided at the end of the outer shoji frame, and this rotating body is used to connect the engaging protrusion of the window frame. A bar located on the indoor side is provided to protrude, and its rotating body is brought into contact with the engagement protrusion of the window frame or the sash frame and rotated, and the rotation of the rotating body causes the bar to engage with the engagement protrusion. It has been proposed that the outer shoji sash be brought into contact with the shoji and the stile is drawn toward the indoor side. However, with this device, the movement of the inner and outer shoji in the closing direction is used to draw the outer shoji stile towards the indoor side, so the outer shoji can be closed and moved at the same time. There was a major problem in that it was not possible to obtain a sufficient attracting effect even if the

OBJECTIVES AND SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the conventional device and makes it possible to forcefully and reliably move an outer shoji sill by rotating a pulling handle pivoted to the middle part of the inner shoji sill.

The same reference numerals as in Embodiment 1 are used for the parts, and C in Alphabella 1- is replaced by f, and the detailed explanation is omitted.In addition, in the present application, the elevating floater has a pulling function and a closing function. There's no need to make it work.

It goes without saying that a roller may be rotatably provided at the tip of the operating portion of the rotational force 11 or the window frame abutting portion.

Effects As described above, in the present invention, the outer shoji drawer is pulled towards the indoor side by rotating the puller handle attached to the middle part of the inner shoji drawer. By rotating the handle in the same way as the crescent of a general sash, the outer shoji can be pulled in, making it easier to pull in the shoji and reducing the expected width of the outer shoji. It has the advantage that it can be easily applied to soundproofing sash that can be used completely for general windows. Furthermore, even if the outer shoji opening stile is pulled in by rotating the pulling handle of the inner shoji opening stile, the pulling of the outer shoji opening stile is not the same as that of the inner shoji opening stile. A lifting block is provided at the end of the shoji, and a rotating cam is provided at the end of the outer shoji frame, which can be rotated by rotating the supporting shaft in the direction of movement of the outer shoji.
The lifting block, which is raised and lowered by the rotation operation of pull-in and AI-A, engages with the engaging part of the rotating cam and rotates the rotating cam, and rotates by the rotation of this rotating cam. Since the window frame abutting part of the cam is brought into contact with the window frame, the outer shoji-drawing stile can be reliably and strongly drawn toward the indoor side by the rotating cam. In addition, the lifting block that is raised and lowered by the rotating operation of the above-mentioned Yoshiko pulling handle rotates the rotating cam. The stile can be pulled toward the indoor side, and the outside shoji can be pulled closer, which has the effect of improving airtightness.
