Description

[Detailed Description of the Invention] This invention relates to a kick-out and shock absorbing device for a smoke exhaust window.

A smoke exhaust window for a building is a smoke exhaust window in which the door is pivoted to the lower frame of the window frame so that it can be raised and lowered freely, and an arm is attached between the door and the window frame to hold the door when it is fully opened. Yes, it is widely known and used.

This type of smoke evacuation window requires that in the event of a fire, the door can be opened by folding it towards the indoor or outdoor side as quickly as possible so that smoke and toxic gases inside the room can be quickly exhausted to the outside. It is necessary to weaken the impact when the door is knocked down as much as possible so that the window glass and arm attachment parts are not damaged by the impact when the door is knocked down.

However, as a conventional smoke evacuation window of this type,
No. 32121 is known, but it only has an extruded hardware made of a V-shaped leaf spring attached to the window bottom frame, and its kicking force is weak because it is close to the window's rotation axis.
Also, the kicking force cannot be adjusted depending on the relationship with the arm. Furthermore, the arm had no structure to prevent impact from the window.

This idea was proposed in view of the above circumstances, and has an extremely simple structure, a small number of parts, and
It is an object of the present invention to provide a kick-out and shock absorbing device for a smoke exhaust window that can be manufactured extremely compactly.

Hereinafter, this invention will be explained with reference to an embodiment shown in the drawings. In the smoke exhaust window 1, the lower stile 5 of the door 4 is pivotally supported on the lower frame 3 of the window frame 2 so that the door 4 can be raised and lowered freely. Moreover, an arm 8 is attached between the vertical frame 6 of the window frame 2 and the vertical stile 7 of the door 4 to support the door 4 when it is fully opened. In this case, the mounting portion of the arm 8 on the window frame 2 side and the mounting portion of the arm 8 on the door 4 side are mounted with their positions shifted left and right on the vertical axis when the door 4 is closed.

In the vertical stile 7 of the door 4, a recess 9 having a substantially groove-shaped cross section and opening toward the vertical frame 6 is formed continuously in the vertical direction of the vertical frame 7, and within this recess 9, a support 10 having a generally groove-shaped cross section is formed. It is attached along the vertical direction of the vertical frame 7, and a holding frame 11, a rod 12, and an adjustment bolt 1 are installed in this support body 10.
3 and a stopper 14 are respectively attached.

The holding frame 11 is formed into a substantially box shape that is elongated in the vertical direction of the support body 10, and has a long hole 15 that is elongated in the vertical direction of the holding frame 11 in its bottom surface and a through hole 16 in its upper end surface.
are formed respectively. Further, mounting pieces 17, 17 are formed at both upper and lower ends of the holding frame 11, and the holding frame 11 is attached by fixing the mounting pieces 17, 17 to the bottom of the support body 10 with setscrews 18, 18. There is.

The rod 12 is installed in the support 10 with its lower end inserted into the holding frame 11 through the through hole 16, and is configured to freely move up and down between the holding frame 11 and the stopper 14.

A cylindrical float 19 is attached to the upper end of the rod 12 by inserting the upper end of the rod 12 into the float 19. A long hole 20 is formed in the float 19 in the vertical direction, and a projection 2 protruding into the long hole 20 is formed at the upper end of the rod 12.
1 is formed, and the float 19 is adapted to slide over a certain range on the upper end of the rod 12.

Also, a stop portion 2 is located approximately in the center of the rod 12.
1' is fixedly attached to the rod 12, and between this stop part 21' and the float 19 there is a coil spring 22 on the float 19 side and a spring receiver 23 on the stop part 21' side.
is inserted through the rod 12 and is attached so that it can freely move up and down.

Furthermore, an adjustment bolt 13 is attached above the holding frame 11 so as to be adjustable in the vertical direction.

Further, a stopper 14 is fixed to the support 10 above the float 19.

The arm 8 has one end rotatably connected to the lower end of the rod 12 through a long hole 15 by a connecting pin 24, and the other end rotatably connected to the vertical frame 6 of the window frame 2 by a connecting pin 25. installed by. In this case, the connecting pins 24 and 25 at both ends of the arm 8 are not aligned in the vertical axis direction when the door 4 is vertically closed within the window frame 2, but are shifted from side to side.

In such a configuration, when the door 4 is vertically closed within the window frame 2, the rod 12 is connected to the arm 8.
is pushed upward by float 19
is locked against the stopper 14,
The protrusion 21 of the rod 12 is connected to the long hole 20 of the float 19.
It is located at the upper end of the float 19 and the stop part 2.
The coil spring 22 between it and the spring receiver 23 stopped by 1' is compressed, and the rod 12 is in a state of being pushed downward by the coil spring 22. In this state, when the door 4 is unlocked (not shown), the rod 12 is pushed down due to the difference in the vertical position of the attachment part between the door 4 and the window frame 2 to which the arm 8 is attached. In conjunction with this, the arm 8 is pushed down and the door 4 is kicked out. After that, the door 4 falls down under its own weight, and when it is fully opened, the protrusion 21 at the upper end of the rod 12 is inserted into the long hole 20 of the float 19.
The coil spring 22 is located at the lower end and is open.

Next, when the door 4 is kicked out and falls down, the rod 12 moves downward in conjunction with the arm 8, and the spring receiver 23 collides with the adjustment bolt 13 attached above the holding frame 11. The coil spring 22 between the float 19 and the spring receiver 23 is compressed again, the opening force of the door 4 is suddenly decelerated, and the impact generated by opening the door 4 is buffered and the door 4 is fully opened.
At this time, by adjusting the position of the adjustment bolt 13 up and down in the vertical direction on the same axis as the rod 12, the compression force of the coil spring and the degree of opening of the door can be adjusted.

Since this invention consists of the above-mentioned configuration, the following effects can be expected.

The device according to this invention can be installed within the vertical frame of the door, and by using one of the coil springs, it can be used both as a force for kicking out the window and as a buffer to weaken the impact caused by the door falling. Since the door can be kicked out and buffered with one device, it can be manufactured extremely compactly.

By appropriately adjusting the protruding length of the upper portion of the adjustment bolt, the inclination angle and buffer amount of the door when fully opened can be adjusted.
