Description

[Detailed Description of the Invention] This invention relates to an opening/closing device for a shield that allows a shield provided between an inner sash and an outer sash of a double sash to be opened and closed while the shoji of the inner sash is closed.

As is well known, in recent years, double sashes with good soundproofing and heat insulation effects have been installed at openings in buildings. When installed on the outside of the room, there will be a suitable amount of space between the inside and outside sashes, so
Double sashes have also come to be manufactured to attach shielding objects such as blinds, movable curtains, or shutters to this space. However, when a shield is provided between the inner and outer sashes, there is a big inconvenience that the shoji of the inner sash must be opened every time the shield is opened or closed.

Therefore, this idea was developed by devising an opening/closing device that guides the operation string of the shield installed between the inner and outer sashes from the outer periphery of the upper frame of the inner sash to the indoor side, so that the shield can be opened and closed while the shoji of the inner sash is closed. This is what I did.

Next, the structure of the present opening/closing device will be explained with reference to drawings of embodiments. Of the inner sash A and the outer sash B that make up the double sash, a shield 10 that can be opened and closed from the outer rail 4 of the inner sash A to the outdoor side is provided. Installation, shield 1
A guide hole 7 is provided in the main wall 2 between the mounting part of 0 and the upper frame outer rail 4 through which an operating string 11 for opening and closing the shield 10 or adjusting lighting is inserted, and on the outer peripheral side of the main wall 2 of the upper frame 1,
A guide groove 8 communicating with the indoor side from the guide port 7 is provided,
The guide groove 8 is formed by cutting out a part of the bis pocket 5 and the grounding piece 6 that protrude outward from the main wall 2 of the upper frame 1, and the operation string 1 is connected to the guide port 7 through the guide groove 8.
1, the guide body 20 is formed in a size that does not protrude from the outer periphery of the inner sash upper frame 1, and the guide groove 8 provided on the outer periphery side of the main wall 2 is fitted.
An inlet 22 that penetrates the main wall guide port 7 and projects toward the inner circumferential side is provided on the outdoor side of the body 21 that fits into the body 21 .
An exit 23 is provided on the indoor side of the building, and the exit 23 is opened to the indoor side, or is opened to the indoor side of the upper frame inner wall 3, and a blind, shutter, curtain, movable curtain, etc. is used as the shielding body 10. be.

Since the proposed opening/closing device has the above structure, after assembling the inner sash A and the outer sash B in the conventional manner, the shield 10 is first attached to the indoor side from the outer rail 4 of the inner sash A, and then the inner sash upper frame 1 is attached. A guide hole 7 is bored in the main wall 2 between the mounting part of the shield 10 and the outer rail 4, and a part of the inner wall 3, the bis pocket 5 and the grounding piece 6 that protrudes outward from the upper frame main wall 2 is A guide groove 8 is provided on the outer circumferential side of the main wall 2 on the indoor side from the perforation position of the guide port 7, and a guide body 20 is inserted into the guide groove 8.
The body part 21 of the guide body 20 is also inserted into the guide port 7.
2 are fitted with the guide body 20 facing toward the inside, and the inlet 22 of the guide body 20 protrudes inward from the main wall 2, while the outlet 23 of the guide body 20 is opened to the indoor side. Before inserting the operating string 11 and leading it to the indoor side, or assembling the inner sash A, provide a guide hole 7 and a guide groove 8 in the inner sash upper frame 1, and fit and fix the guide body 7 therein. After assembling the inner sash A, insert the operation string 11 of the shield 10 into the guide inlet 22 that opens toward the inner circumference from the main wall 2 of the inner sash upper frame 1, It is led from the section 21 to the outlet 23 and hangs down toward the indoor side. As above, the shield 1 is placed on the upper frame 1 of the inner sash A.
If the opening/closing device 0 is installed and the operating string 11 of the shield 10 provided between the inside and outside sashes A and B is guided to the indoor side by the guide body 20 of the opening/closing device, the operating string 11 hanging toward the indoor side can be operated. The shield 10 can be opened and closed with the shoji S of the inner sash A closed.

Therefore, if the opening/closing device of the present invention is installed on the upper frame of the inner sash, the shoji of the inner sash will not need to be opened.
Because the shield installed between the inner and outer sash can be opened and closed,
The shield can be opened and closed easily, and can be opened and closed in the same way as conventional blinds. Moreover, the opening/closing device can be installed by simply providing a guide hole and a guide groove in the inner sash of the double sash, fitting and fixing the guide body into these, inserting the operating string through the guide body, and guiding it to the indoor side. Not only is it extremely easy, but
The guide body of the opening/closing device is attached to the outer periphery of the main wall of the upper frame of the inner sash so that it does not protrude beyond the outer periphery, so it does not interfere with the opening and closing of the shoji that is inserted into the inner sash, and it is also easy to install the inner sash. No hindrance. Furthermore, since the operating string of the shield is guided in the hollow part of the guide body and hangs down until it reaches the exit, there is no need for accessory parts such as pulleys, and there is no risk of the operating string being frayed by the edges of the frame. Furthermore, even when replacing the operating string, the operating string can be guided by the guide by inserting the string into the hollow part of the guide from indoors or outdoors, making the operation easier.
