Description

[Detailed Description of the Invention] Technical Field The present 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 PROBLEMS Conventionally, this type of pulling device has a pulling handle that is pivoted to the outer shoji sliding frame, and a pulling block that is raised and lowered by the rotation of the pulling handle can be raised and lowered. A device has been put into practical use in which the pulling block is engaged with the window frame to draw the outer shoji sliding stile toward the indoor side and to pull the inner shoji sliding stile toward the indoor side. However, in the case of the above-mentioned pulling device, although there is an advantage that the outer shoji-drawing stile pushes the inner shoji-drawing stile toward the indoor side and reliably pulls the two shoji-drawing stile together, Because it is installed on the stile, it is difficult for ordinary people who are accustomed to operating the crescents of general sash doors (the inner shoji is pivoted to the stile) to operate it, and the inner and outer shoji cannot be completely retracted. In order to do this, the expected width of the outer shoji had to be increased, which created a problem that made it unsuitable for a completely sliding soundproof sash for general windows. Therefore, in order to solve the above problem, as shown in Japanese Utility Model Publication No. 57-50466, a Gremon handle was pivoted to the inner shoji sliding stile, and a receiving bracket was made rotatable on the outer shoji sill. It is pivoted and biased in one direction, and the rotating operation of this Gremont handle rotates the receiving metal fitting against the biasing force, and the rotation of this receiving metal fitting causes the outer shoji to be attached to the edge of the frame. A device has been proposed in which the outer shoji-drawing frame is pulled toward the indoor side by operating a pulling member, but in this device, the return operation of the receiving metal fittings and the pulling member is performed by a spring. As a result, there is a fatal problem in that the return operation of the outer shoji folding stile when the pull is released is uncertain, which is why it has not been put to practical use. In addition, as shown in Japanese Utility Model Publication No. 57-45323, a rotating body that can rotate indoors and outdoors on a vertical axis is provided at the end of the outer shoji frame, and this rotating body engages the window frame. A rod-shaped member located on the indoor side of the joint projecting body is provided in a protruding manner, and the rotary member is brought into contact with the engagement protrusion of the window frame or the internal shoji frame and rotated, and the rod-shaped member is rotated by the rotation of the rotary member. A device has been proposed in which the outer shoji stile is drawn toward the indoor side by contacting the engaging protrusion. However, with this device, the movement of the inner and outer shoji in the closing direction is used to draw the outer shoji stile toward the indoor side, so the closing movement and the pulling movement of the outer shoji are simultaneous. There was a major problem in that it was not possible to obtain a sufficient attracting effect because the

OBJECTIVES AND SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the conventional device, and provides a method for making the outer shoji folding stile stronger and stronger by rotating a pulling handle pivoted to the middle part of the inner shoji folding stile.

In addition, the lifting block 41 is connected to the lower frame 2 and the inner shoji frame 3.
Close the gap between 7. Therefore, the upper and lower indoor side surfaces 20a and 20b of the outer shoji 20 are fitted with the frame packing 6,
13, and the indoor side surface of the outer shoji sill 24 is crimped to the lining packing 50 and closing packing 44 of the inner shoji sill 37, and the inner and outer shoji 2
1 and 20 are airtightly closed. Rotate the pull handle as shown above to pull the outer shoji frame 2.
4 toward the indoor side, the outer shoji 20 is immediately pulled toward the indoor side with the outer shoji 20 almost completely closed. The frame 24 can be pulled together. In addition, the pulling force of the outer shoji frame 24 by the rotating cams 30, 34 can be increased by the lengths of the engaging portions 30a, 34a and the window frame contact portions 30b, 34b, resulting in a large pulling effect. Obtainable. Next, when the pulling handle is rotated in the unlocking direction, the elevating rods 38 and 39 are moved toward each other, lowering the elevating block 40 and raising the elevating block 41. Therefore, rotating cam 3
0 and 34 are returned and rotated by springs 33 and 36 to release the outer shoji sliding frame 24, and the lifting blocks 40 and 41 release the inner sliding sliding frame 37 from being pulled together.

Next, FIGS. 8 and 9 show different embodiments of the rotary cam and the actuating section, in which an engaging pawl 51 is formed at the tip of the engaging section 30ae of the rotating cam 30e, and the actuating section 48 is actuated. An engagement groove 52 is formed on the surface 48a, and this engagement groove 52 engages with the engagement claw 51 to rotate the rotary cam 30e. It should be noted that the same constituent parts as in the above embodiment are given the same reference numerals as in the above embodiment with an alphanumeric letter "e" added thereto, and redundant explanation will be omitted. Further, in the present application, there is no need for the lifting block to also have a pulling function or a closing function. It goes without saying that a roller may be rotatably provided at the tip of the actuating part of the rotary cam or the window frame abutting part.

Effects As described above, in the present invention, the internal shoji sliding stile is pulled toward the indoor side by rotating the pulling handle pivoted to the middle part of the internal shoji sliding stile. Therefore, by rotating the pulling handle in the same way as the crescent of a general sash, the inner and outer shoji can be pulled together, making it easier to pull the shoji together. This has the advantage that the expected width of the window can be reduced, and it can be easily applied to completely sliding soundproof sashes for general windows. Furthermore, even if the outer shoji sill is pulled in by rotating the pulling handle of the inner shoji stile, the inner shoji sill cannot be pulled in. A lifting block is provided at the end of the stile, and a rotary cam is provided at the end of the outer shoji-drawing stile, which can rotate around a support shaft in the direction of movement of the outer shoji, and the pulling handle can be rotated. The actuating part of the lifting block, which is raised and lowered by Since this is done, the outer shoji-drawing stile can be reliably and strongly drawn toward the indoor side by the rotating cam. In addition, as mentioned above, since the lifting block that is raised and lowered by rotating the pull handle rotates the rotating cam, the outer shoji cannot be opened after the inner and outer shoji have been moved in the closing direction. The stile can be pulled toward the indoor side, and the outside shoji can be pulled closer, which has the effect of improving airtightness.
