Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a smoke exhaust window that opens to exhaust smoke when a fire occurs.

Prior Art As shown in Fig. 1, a smoke exhaust window is a window frame in which the upper horizontal stile b of a shoji B is pivotally connected to the upper horizontal frame a of a window frame A so that it can be opened and closed in an out-of-plane direction using a hinge c. Window frame side brackets e fixed to the left and right stiles d, d of A; shoji side brackets g fixed to the left and right stiles f, f of shoji B;
A pair of left and right stay dampers h, h are pivotally connected across g, respectively, and a pair of left and right stay dampers h,
It is known that the shoji B is biased toward the open side by the lever h, and the shoji B is pulled and held toward the closed side by a rope or the like, and the shoji B is opened by loosening the rope or the like.

However, in this smoke exhaust window, the stay damper h is installed vertically along the vertical frame d and the vertical frame f, which is not good for the appearance. If the stay damper h is built in and installed, the dimensions of the vertical frame d and the vertical stile f will become large, which will be disadvantageous in terms of cost, and the work of installing the stay damper h will become troublesome.

Purpose of the invention The purpose is to provide a stay damper that is low in cost, easy to install, and has an excellent appearance.

Structure of the invention Both ends of the stay damper are pivotally connected to the upper part of the lower horizontal frame of the window frame and the upper indoor side of the lower horizontal stile of the shoji so that they can swing vertically and horizontally.

Embodiment Fig. 2 is a schematic front view of a sash equipped with a smoke exhaust window. The upper horizontal stile 4 of the shoji B is pivotally connected to the upper horizontal frame 2 of the window frame A 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, 7 are laterally (horizontally) pivotally connected across the lower horizontal stile 6 and the blind 3 of the shoji B.

Reference numerals 8 and 8 indicate the left and right vertical frames of the shoji B, and the shoji B has a panel member 9 made of glass or the like mounted inside the square frame assembly formed by the upper and lower horizontal frames 4 and 6 and the left and right vertical frames 8 and 8. be.

a is the left and right vertical frames 1, 1 in the connecting wall 3c of the no-mume 3
It is connected to the rest position via a bracket 20 and a ball joint 21 so that it can freely swing up and down and left and right.
The movable side 7b has a bracket 2 at a position closer to the longitudinal center of the indoor wall 6a of the lower side stile 6 of the shoji B.
2. They are connected via a ball joint 23 so that they can freely swing vertically and horizontally, and the stay damper 7 is in a substantially horizontal state when the shoji B is closed.

A pulley 25 is attached via a bracket 24 to the longitudinal center position of the indoor side wall 6a of the lower horizontal stile 6 of the shoji B, and a first pulley 25 is attached to the blind connecting wall 3c.
Second guide pulleys 26 and 27 are attached, and a rope 29 fixed to the connecting wall 1c of one of the vertical frames 1 via a spring 28 is attached to the first guide pulley 26, 27.
6. The rope 29 is extended downward via the pulley 25 and the second guide pulley 27, the hole 30 in the connecting wall 1c of the other vertical frame 1, and the third guide pulley 31 provided on the inner surface of the indoor wall 1a. The other end is the hole 3 in the indoor wall 1a.
The rope 29 is pulled out to the indoor side from 2 and wound around a winder or the like, and when the rope 29 is wound up with the winder or the like, the shoji B is rotated in the direction of closing against the stay damper 7. The spring force of the spring 28 is greater than the urging force of the stay damper 7.

Therefore, in normal times, the shoji B can be held in a closed state by winding the rope 29, and the inner walls 4a, 6a, 8a, 8a of each frame chamber are
Crimp 0, 11, 12, 12 and attach shoji B and window frame A
It is possible to maintain airtightness and watertightness between the

In addition, since the stay damper 7 is installed horizontally on the vertical frame 3 and the lower horizontal stile 6, it is not visible from the outside, resulting in a clean and excellent appearance. It is advantageous in terms of cost because there is no need to increase the size, and the stay damper 7 can be easily installed from above the blind 3, making the installation work simple and easy.

Also, move the movable side 7b of the stay damper 7 to the lower horizontal stile 6.
Since the windows are connected to the central position in the longitudinal direction, even if the window frame A is wide, the shoji B will not twist, and there is no need to increase the rigidity of each frame of the shoji B even if the window frame A is wide. .

In addition, in the event of a fire, etc., by loosening the rope 29, the shoji B is rotated upward on the outdoor side around the hinge 5 by the biasing force of the stay damper 7, and the window frame A is immediately opened to prevent smoke. can be discharged.

At this time, the stay damper 7 swings upward while swinging toward the outdoor side, but since it is connected to the blind 3 and lower horizontal stile 6 via the ball joints 21 and 23, the stay damper 7 swings toward the outdoor side and upward. can swing smoothly.

Furthermore, since the spring force of the spring 28 is made stronger than the biasing force of the stay damper 7, the rope 29 is
When the spring 28 is further pulled, the spring 28 is pulled, and when the rope 29 is locked and fixed in this state, the rope 29 is pulled by the spring force of the spring 28, and the shoji B is swung toward the closing side via the pulley 25. The moving force acts, and the shoji B can be reliably held in the closed state, and each sealing material 10, 11,
