Description

[Detailed description of the invention] Industrial application field The present invention is a casement window in which a shoji rotates in an out-of-plane direction relative to a window frame, such as a vertical rotating window, a horizontal rotating window, and an outward opening window. This relates to a safety device that prevents shoji doors from rotating due to strong winds.

PRIOR TECHNOLOGY A tension stopper is provided between the window frame and the shoji, and when the shoji is rotated outward to the open position, the window frame and the shoji are connected by the tension stopper, and the shoji is Casement windows are known that are designed to prevent strong winds from blowing them up.

The problem that the invention aims to solve: The tension stopper must be manually operated between the stopped state and the free state, and when opening and closing the shoji, one hand holds the shoji and the other hand holds the tension stopper. Since the shoji is operated, if a person carelessly removes the shoji while it is in a free state, or a gust of wind acts, the shoji will be agitated and collide with the wall of a building, damaging the shoji, or causing the shoji to hit a person. This is extremely dangerous as there is a risk of collision and injury.

Means and action for solving the problem A cable is provided on the window frame side so that it can be drawn out by a predetermined amount and maintained biased, and the extended side is connected to the shoji side, so that the cable can be pulled out regardless of the tension stopper. It is possible to control the rotation of the shoji using a section.

Embodiment FIG. 4 is a schematic front view of a vertical rotating window. The window frame A is a rectangular frame made up of an upper frame 1, a lower frame 2, and left and right vertical frames 3, 3. is shoji B
is attached so that it can rotate freely in the out-of-plane direction.

Shoji B has an upper stile 4, a lower stile 5, and left and right vertical stile 6, 6 framed in a rectangular shape, and a glass 7 is mounted inside the frame, and the upper stile 4 and lower stile 5 are connected to each other via a vertical shaft 8. It is rotatably connected to the upper frame 1 and the lower frame 2.

FIG. 1 is a schematic perspective view of the shoji B in an open state, in which a tilting stopper 10 is attached across the lower frame 2 and the lower stile 5, and the tilting stopper 10 is attached to the lower frame 2 in an out-of-plane direction. The arm 11 is rotatably supported, and the receiving piece 12 is fixed to the lower frame 6. The arm 11 is provided with a pin 13, and the receiving piece 12 is formed with a hole 14 into which the pin 13 fits. By rotating the arm 11 and fitting the pin 13 into the hole 14, the shoji B is connected to the window frame A in a locked state, and when the pin 13 is removed from the hole 14, it is in a free state. It has been done.

A safety device 20 according to the present invention is provided between one vertical frame 3 and one vertical frame 6, and this safety device 20 is provided in a container 21 attached to the vertical frame 3 so as to be freely extended and retracted. , and a cable 22 such as a chain kept biased in the retracting direction, and a receiving member 23 fixed to one of the vertical frames 6.
2 and a receiving member 23.

FIG. 2 is an exploded perspective view of the safety device 20. The container 21 has a long cylindrical shape and is fixed to the top of a plate-like mounting plate 24, and an elastic member 25 such as a spring is provided inside the container 21. One end of the elastic member 25 is attached to the upper wall 21a of the container 21, and one end of a cable 22 is connected to the other end. A hook 29 is connected to the tip of the guide body 27 which projects outward and is rotatably supported at the bottom of the mounting plate 24 through a hole 28. A stopper 30 having a shape and size that prevents it from being pulled out from the hole 26 is fixed to the portion, and the length of the cable 22 that is fed out from the container 21 is regulated by the stopper 30 coming into contact with the lower wall 21b. 25 maintains the bias in the retracting direction.

The receiving member 23 has a receiving piece 32 fixed to a mounting plate 31, and a hole 33 is formed in the receiving piece 32, and a hook 29 can be engaged with and released from the hole 33.

FIG. 3 is a cross-sectional view of the state in which the safety device 20 is installed.
b and 3c form a long member having a U-shaped cross section, and a pair of seal receiving pieces 40 and 41 are integrally formed inside and outside the side wall 3a in the longitudinal direction.

Vertical stile 6 is indoor, outer walls 6a, 6b and inner and outer walls 6
A pair of AT materials 42, 43 are attached to the inside and outside of the outer wall 6d, and the pair of AT materials 42, 43 are pressed against the seal receiving pieces 40, 41. to seal the space between the vertical frame 3 and vertical frame 6, and a pair of AT
A vertical space 44 is formed between the materials 42 and 43, the outer wall 6d of the vertical stile 6, and the side wall 3a of the vertical frame 3, and the mounting plate 24 and the mounting plate 31 of the safety device 20 are positioned in this vertical space 44. are attached to the side wall 3a and the outer wall 6d with screws 34 and 35, and the safety device 20 is located in the vertical space 44 so that it cannot be visually seen from the outside when the shoji B is closed.

Because of this, when the shoji B is closed, the cables 22 are drawn into the container 21 by the elastic material 25 and stored, so that the cables 22 are connected to the AT materials 42, 43 and the seal receiving pieces 40, 41. There is no need to be caught in between.

Furthermore, when opening the shoji B, the cables 22 are let out against the elastic material 25, and when the cables 22 are let out by a predetermined amount, the stopper 30 comes into contact with the lower wall 21b of the container 21 and prevents the rotation of the shoji B. Therefore, even if a person inadvertently lets go of the shoji B or is agitated by a gust of wind while the agitation stopper 10 is in a free state, the shoji B will rotate more than necessary and cause damage to the building wall or people. It is safe and there is no collision.

Note that the maximum amount of extension of the cables 22 is equal to the maximum rotation range of the shoji B that is regulated by the anti-tilt tool 10.

Moreover, since the cable 22 is let out and retracted through the hole 28 of the guide body 27, it is smoothly let out and retracted.

5 and 6 are a detailed perspective view and a cross-sectional view of the stopper 30, and the cable 22 has a large number of balls 50.
The stopper 30 has a cylindrical shape with a hole 52 through which the ball 50 is inserted, and an annular groove 53 is formed on its outer peripheral wall, and a radial direction opening the annular groove 53 into the hole 52 is formed. A notch 54 is formed in the annular groove 53, and a substantially arc-shaped outer peripheral piece 56 of the spring ring 55 is fitted in a snap manner, and a bifurcated stop piece 57 is formed in the notch 54.
is inserted, and this stop piece 57 fits into the connecting rod 51 and comes into contact with the ball 50, thereby fixing the stopper 30 to the cable 22.

In this way, the stopper 30 can be moved in the longitudinal direction along the cable 22 by removing the spring ring 55, and the stopper 30 can be fixed to the cable 22 by attaching the spring ring 55. The maximum amount of extension of the cable 22 can be adjusted by fixing it at any position in the longitudinal direction of the cable 22.

In addition, the cable 22 is provided on the vertical frame 3 through an elastic material so that it can be freely drawn out and maintained in a biased manner.
A receiving member may be provided on the vertical frame 3 to interfere with a stopper provided on the cable 22 to regulate the amount of extension, or the maximum extension length of the cable may be regulated by the amount of elastic deformation of the elastic material itself. .

Effects of the invention: The maximum rotation range of the shoji B can be regulated by the cables 22 regardless of the anti-swinging device, so when the anti-shoji device is in a free state, a person may inadvertently take their hand off the shoji B, or a gust of wind may Even if it is pushed, the shoji B will not rotate more than necessary, so it will not collide with building walls or people, making it safe.
