TECHNICAL FIELD OF THE INVENTION
The present invention relates to a sash, and more particularly, to a sash with a constant pulling amount when closing a shoji and a constant initial opening / closing force of the shoji.
[0002]
[Prior art]
In a sash in which a shoji is provided in a sash frame consisting of an upper frame, a lower frame, and left and right vertical frames so as to be able to open and close in a single pull or pulling manner, as shown in FIG. In order to increase the height, a pulling piece 10 for pulling the shoji 3 against the airtight material 9 of the vertical frame 1c with the movement of the shoji 3 at the time of closing is provided. The pulling piece 10 has a tapered portion 14 guided by fins 13 provided on the vertical frame 1c.
[0003]
In such a sash, it is possible to adjust the crescent receptacle of the crescent which is a locking device in consideration of a manufacturing error and a construction error, and the pulling piece 10 also has a hole 16 of a screw 25 which is a fixing tool. With the elongated hole, the amount of pulling of the shoji 3 can be adjusted by adjusting the inside and outside directions.
[0004]
[Problems to be solved by the invention]
However, in the sash described above, due to the structure of the pulling piece, when the shoji is closed vigorously or the crescent receiver is adjusted tightly, the shoji may be further drawn than the regular size. FIG. 7A shows a regular closed state of the shoji, and FIG. 7B shows an irregular closed state such as when the shoji is vigorously closed. For example, if the dimension u between the normally closed sash 3 and the vertical frame 1c is 3 mm, and the drawing amount t is 1.6 mm, the dimension ux between the irregularly closed sash 3 and the vertical frame 1c is 1. 5 mm, and the drawn amount tx was 1.2 mm. For this reason, the frictional resistance of the airtight material 9 between the shoji 3 and the vertical frame 1c increases, and the initial opening / closing force at the time of opening the shoji 3 becomes heavy, thereby causing a problem that the opening / closing operability deteriorates. . In the case of a sash for a building, since wind pressure is applied to the shoji, the initial opening / closing force when the shoji is opened tends to be further increased.
[0005]
The present invention has been made in consideration of the above-described circumstances, and it is possible to make the pulling amount constant regardless of the opening / closing speed of the shoji and the adjustment amount of the crescent receptacle, and to make the initial movement opening / closing force of the shoji a constant. The purpose is to provide a sash that can be used.
[0006]
[Means for Solving the Problems]
The sash according to the present invention is provided with a shoji in a sash frame composed of an upper frame, a lower frame, and left and right vertical frames so as to be able to open and close in a single pull or pulling manner. A pulling piece for pulling the vertical frame through to provide a tapered portion guided by a fin provided on the vertical frame, and a position of the shoji when closed by contacting the fin. Is provided integrally with or separately from the pulling piece, and the amount of regulation can be adjusted in the opening and closing movement direction of the shoji.
