Description

[Detailed description of the invention] This invention relates to an inward-folding window with an insect-proof screen for ventilation, which is housed in a sash frame (integrated with a sash frame) in which a sliding-down shoji screen and an insect-proof screen are housed in that order from the indoor side.

Conventional sliding windows have the drawback that when the shoji is opened, wind, rain, and dust can blow directly into the room, and insect screens must be installed separately.

The purpose of this project is to eliminate these drawbacks by making the shoji fold inward so that ventilation can be achieved in good condition, and by making it possible to integrally attach an insect screen to the outside of the shoji. However, it can prevent wind, rain, and dust from directly entering the room during ventilation, and can also prevent pests from entering the room.The details of the present invention will be explained below with reference to the drawings.

In Fig. 1, the sash frame consists of left and right vertical frames 2, 3, upper and lower horizontal frames 4, 5, and a blind 6, and a sliding shoji 7 is fitted between the upper horizontal frame 4 and the blind 6. An insect repellent net 8 is stretched over the exterior surface of the room, and a shoji 9 is fitted between the lower horizontal frame 5 and the blind 6.
is embedded.

In the above-mentioned sash frame 1, the left and right vertical frames 2, 3, the upper horizontal frame 4, and the blind 6 are provided with channel-shaped insect-screening grooves 10, respectively, on the outdoor side surfaces (left and right). The vertical frame insect-proof netting grooves are not shown), these insect-proof netting grooves 10
The end of the insect screen 8 is press-fitted into the hole 7 along with beads 11 made of an elastic material such as rubber or synthetic resin, thereby stretching the insect screen 8 in a stretched state.

In addition, the vertical lateral force gusset of the inward-folding shoji 7 is placed on the surface of each indoor side of the insect-proof netting groove 10 of the upper horizontal frame 4 of the sash frame 1 and the insect-proof netting groove 10 of the blind 6. 14,1
Abutting walls 27 and 27 are respectively provided to abut against the indoor sides of the seats.

The inward folding shoji 7 has a glass 16 fitted into a frame consisting of left and right gussets 12 and 13 and top and bottom lateral gussets 14 and 15, and a hinge 17 is installed at the lower end of the left and right edge sills 12 and 13 on the indoor side. One blade 18 is fixed with a screw 19,
The other blade 20 of the hinge is fixed to the left and right vertical frames 2 and 3 of the window frame, respectively.

21 is the axis of the hinge.

22 is a locking device for the shoji 7 that folds inward. When the shoji is closed, a trapezoidal cam 23 engages the hook-shaped spring I to the collar 24 to maintain the closed state; however, when the hook 25 is pulled downward, the above-mentioned The cam 23 retreats and comes off the spring stopper 24, thereby causing the upper part of the shoji to fall toward the indoor side and open.

26 is a sealing material.

In this case, the present invention is not limited to the window configuration of the folding shoji 7 alone, but can also be applied to transoms of terrace windows, entrance sliding doors, doors, etc. as appropriate.

In addition, in the scope of claims for utility model registration in this specification, the horizontal frame material means the horizontal frame material including the upper and lower horizontal frames 4, 5 and the blank 6, and the vertical frame material means the left and right vertical frames. 2.3 and others.

This invention's inward-folding window with an insect-proof screen for ventilation has a structure in which the shoji is folded inward, and the insect-proof screen is integrally stretched on the outside of the shoji, so as shown in Figure 3, ventilation can be achieved in good condition. It is possible to prevent wind, rain and dust from directly entering the room during ventilation, and since there is no gap between the window frame and the sash frame, it has a great insect repellent effect against the intrusion of pests. It can be minimized to the size required for ventilation, insects etc. do not stick to the glass surface of the shoji, and the screen door can be installed separately, and the installation frame for installing the insect screen can be installed separately on the window frame. It is easy to construct and install, and since it has an abutting wall for the folding shoji, it provides good rain protection, and the groove for installing the insect screen and the accommodating part for the folding shoji are spaced apart. Therefore, it is extremely effective in practical terms, such as preventing the shoji from coming into contact with the insect screen.

Claims (1)

[Scope of utility model registration request] A sash frame is created by pre-framing upper and lower horizontal frames and left and right vertical frames, which are integrally formed with a shoji accommodating part for folding inward on the indoor side and a groove for installing an insect screen on the outdoor side, separated from the above-mentioned shoji accommodating part for inside. The lower part of the shoji on both sides of the shoji is pivotally connected to the left and right vertical frames by hinge members, and the upper part of the shoji is stored in the shoji storage part for folding inward so that the upper part of the shoji can be folded inward toward the indoor side. The sash frame is provided with an abutting wall that brings the indoor side of the stile into contact with the indoor surface, and an insect screen is stretched in the groove for installing the insect screen, and the sash frame is folded inward from the indoor side, and the insect screen is placed in that order. A window that folds inward with an insect-proof screen for ventilation, which is housed in one piece.
