[Problem that the idea aims to solve]

However, with this smoke exhaust window, the stay damper h is vertically aligned along the vertical frame d and the vertical frame f. Since it is attached, it is unfavorable in terms of appearance, and in order to improve the appearance, vertical frame d. When the stay damper h is installed inside the vertical stile f, the dimensions of the vertical frame d and vertical stile f are becomes large, which is disadvantageous in terms of cost, and the installation work of the stay damper h becomes complicated. I end up collapsing. In addition, a pair of left and right stays are installed on the left and right vertical frames d and d of window frame A and the left and right vertical frames f and f of shoji B. Since the damper h is connected, the width of the window frame A becomes wider and the width of the shoji B (length in the in-plane direction) When shoji B becomes larger, twisting tends to occur in shoji B, and the rigidity of the stile of shoji B is increased. There must be.

0004 Therefore, the present invention is low in cost, allows easy installation of the stay damper, and Not only can the appearance be improved, but even if the width of the shoji is large, the rigidity of each stile can be improved. To provide a smoke exhaust window that prevents twisting of shoji without increasing the size of the shoji. aimed to.

[0005]

[Means to solve the problem]

A window frame A formed into a rectangular shape by upper and lower horizontal frames 2, 3 and left and right vertical frames 1, 1, and this window Inside frame A, shoji B is installed with its upper part rotatably connected so that it can be opened and closed to the outside. It is a smoke exhaust window and stays at a position close to the left and right vertical frames 1 and 1 at the upper part of the lower horizontal frame 3. One end of the damper 7 is connected to be able to swing vertically and horizontally, and the stay damper 7 to a position close to the center in the longitudinal direction at the bottom of the shoji B, swinging it vertically and horizontally. Smoke exhaust windows that are movably connected.

[0006]

[Effect]

It is sufficient to install the stay damper 7 between the upper part of the lower horizontal frame 3 and the lower part of the shoji B. Therefore, the stay damper 7 can be easily installed, and when the shoji B is closed, the stay damper 7 can be easily installed. Since the damper 7 is not exposed to the outside, not only the appearance can be improved, but also the vertical frame The dimensions of the vertical stile are smaller, reducing costs, and the power of the stay damper 7 acts toward the longitudinal center of the bottom of shoji B, increasing the rigidity of each stile even if the width of the window frame is large. Shoji B does not twist without making it larger.

【Example】

FIG. 2 is a schematic front view of a sash equipped with a smoke exhaust window, showing left and right vertical frames 1, 1 and an upper horizontal frame 2. A window frame A is formed by a lower horizontal frame 3 of the window frame A, and a shoji B is attached to the upper horizontal frame 2 of the window frame A. The upper horizontal stile 4 is pivotally connected by a hinge 5 so that it can be opened and closed in an out-of-plane direction. , a pair of left and right stay dampers 7 are placed horizontally across the lower horizontal stile 6 and lower horizontal frame 3 of the shoji B. (Horizontal) Pivot connection. 8 and 8 are the left and right stiles of shoji B, and shoji B has upper and lower horizontal stiles 4 and 6 and left and right stiles 8 and 8. A panel member 9 made of glass or the like is mounted inside the square frame assembly.

[0008] FIGS. 3 and 4 are detailed longitudinal and cross-sectional views of FIG. 2d and the connecting wall 2c form an upward U-shape, and a stepped portion 2d is formed on the outdoor side. A mounting groove 2'd for the upper and horizontal sealing material 10 is formed in the stepped portion 2d. The lower horizontal frame 3 includes indoor/outside walls 3a, 3b and a connecting wall 3c, and has a stepped portion 3 on the outdoor side. d is formed, and a mounting groove 3'd for the lower horizontal sealing material 11 is formed in the stepped portion 3d. In both cases, a rising wall 3e is integrally formed on the indoor side, and the stay damper 7 is connected from the indoor side. It is also made so that it cannot be seen visually. The vertical frame 1 includes indoor/outside walls 1a, 1b and a connecting wall 1c, and has a stepped portion on the outdoor side. 1d is formed, and a mounting groove 1'd for the vertical sealing material 12 is formed in the stepped portion 1d. be. The upper and lower horizontal stiles 4 and 6 and the left and right vertical stiles 8 and 8 of the shoji B are each stepped at 2d, 3d, and 1d. - Facing 1d, each indoor wall 4a, 6a, 8a, 8a has each sealing material 10, 11, 1 It is designed to be crimped to 2.12.

[0009] The fixed side 7a of the pair of left and right stay dampers 7 is connected to the connecting wall 3c of the lower horizontal frame 3. At the left and right vertical frames 1 and 1 position, the upper and lower, left and right The movable side 7b is connected to the indoor side wall of the lower horizontal stile 6 of the shoji B. 6a through the bracket 22 and the ball joint 23. They are connected so that they can swing freely downward and left and right, and when shoji B is closed, the stay The amplifier 7 is arranged in a substantially horizontal state.

0010 A bracket is provided at the longitudinal center position on the indoor side wall 6a of the lower horizontal stile 6 of the shoji B. A pulley 25 is attached via a shaft 24, and first and second guide slides are attached to the lower horizontal frame connecting wall 3c. It is attached to the cars 26 and 27, and a spring 28 is attached to the connecting wall 1c of the one vertical frame 1. The rope 29 fixed through the Through the wheel 27, the hole 30 of the connecting wall 1c of the other vertical frame 1 is provided on the inner surface of the indoor side wall 1a. The rope 29 is extended downward through the third guide pulley 31, and the other end of the rope 29 is connected to the indoor wall 1. It is pulled out to the indoor side through the hole 32 of a and is wound around a winder, etc. When the rope 29 is wound up, the shoji B is rotated in the closing direction against the stay damper 7. The spring force of the spring 28 is applied to the stay damper 7. It is made bigger than the force.

[0011] However, under normal circumstances, the shoji B cannot be held closed by winding the rope 29. At the same time, each frame chamber inner side wall 4a, 6a, 8a, 8a is sealed with each sealing material 10, 11, 1. 2.12 can be crimped to maintain airtightness and watertightness between the shoji B and window frame A. In addition, since the stay damper 7 is installed horizontally on the lower horizontal frame 3 and the lower horizontal stile 6, It is not visible to the naked eye, resulting in a clean and attractive appearance, and the vertical frame It is advantageous in terms of cost because there is no need to increase the dimensions of the vertical stile, and The stay damper 7 can be easily installed from above the frame 3, which simplifies the installation process. Ru. Also, the stay damper 7 can be visually observed from the indoor side by the rising wall 3e of the lower horizontal frame 3. The interior will look cleaner and better without being overly cluttered.

0012 Also, the movable side 7b of the stay damper 7 is connected to a position closer to the center in the longitudinal direction of the lower horizontal stile 6. Therefore, the force of the stay damper 7 acts on the longitudinal center of the lower stile 6, and the window frame Even if A is wide, shoji B will not twist without increasing the rigidity of each stile. Even when used as a wide smoke exhaust window, it is not necessary to increase the rigidity of each stile of the shoji B. In addition, in the event of a fire, etc., the stay damper 7 can be attached by loosening the rope 29. Due to the force, the shoji B is rotated upward on the outdoor side around the hinge 5, causing the window frame A to move quickly. It can be opened quickly to release smoke. At this time, the stay damper 7 swings upward while swinging toward the outdoor side, but the ball joint 2 Since it is connected to the lower horizontal frame 3 and the lower horizontal stile 6 via 1 and 23, the stay damper 7 is connected to the lower horizontal frame 3 and the lower horizontal stile 6. It can swing smoothly outward and upward.

[0013] Also, the spring force of the spring 28 is made stronger than the biasing force of the stay damper 7. Therefore, after winding up the rope 29 and closing the shoji B, pull the rope 29 further. When the spring 28 is pulled and the rope 29 is locked and fixed in this state, the spring 28 is pulled. The rope 29 is pulled by the spring force of the ring 28, and the pulley 25 A force that swings the shoji B toward the closing side acts through the shoji B, ensuring that the shoji B remains closed. At the same time, each sealing material 10, 11, 12, 12 is attached to each frame chamber inner wall 4a, 6a, 8a and 8a can be reliably pressed together to improve airtightness and watertightness. In addition, the sealing materials 10, 11, 12, 12 and the inner walls 4a, 6a, 8a, 8 If the dimensional accuracy of a is improved, the rope 29 can be connected directly to the vertical frame 1 without providing the spring 28. It may be fixed directly. In addition, although the stay damper 7 was connected by ball joints 21 and 23, it was also connected by a cross joint, etc. You can tie it. In other words, it is sufficient to connect them so that they can swing vertically and horizontally.

[0014]

[Effect of the idea]

It is inexpensive, allows easy installation of the stay damper 7, and has an excellent appearance. Furthermore, even if the window frame is widened and the width of shoji B becomes larger, it will not be an obstacle. The rigidity of each stile of shoji B is increased so that it can be used as a wide smoke exhaust window without twisting of the shoji B. There is no need to do so.
