Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a smoke exhaust window with a kick-out arm using an extruded aluminum alloy member.

(Prior technology) Smoke exhaust windows installed in mid-to-high-rise buildings such as buildings, hospitals, and schools are used for forced smoke exhaust to prevent smoke damage in the event of a fire. The lower frame of the window frame of a folding window or outward folding window and the lower stile of the window shoji are connected with a screw, and a strong torsion coil spring is installed at the pivot of this screw, and can be deployed separately in case of an emergency. By releasing the locked lock, the window is rapidly opened inward or outward by the strong return force of the torsion coil spring, making it possible to exhaust smoke. In the past, windows with the structure of For example, Utility Model Publication No. 35-29458 describes an idea in which panel fasteners are fixed to the inside of the opening/closing door, and a linear spring is attached between the two fasteners. In addition, in a TV reflector folding device, there is an example of an invention in which an unequal pitch coil spring having a tightly wound part is stretched between the reflector support plate and the machine case, for example, by It is described in the specification and drawings attached to the application No. 55-4051 (Utility Model Application No. 56-108114).

(Problem to be solved by the invention) However, with the above-mentioned product in which a torsion coil spring is attached to the pivot part of the screw, it is difficult to hold a window shoji that has a considerable weight.
The return force of the spring needs to be strong in order to apply a reliable opening force at the lower part of the shoji. If the impact is not softened, there is a risk of damaging the glass of the window shoji, and if the shock absorber installed as a preventive measure is a spring, the shoji will bounce, and an air damper like the one exemplified above may cause the shoji to bounce. If installed, the structure will be complicated and the price will be high.Furthermore, due to the use of thick torsion coil springs in the longitudinal direction, the gap between the outer frame of the window and the vertical frame of the shoji screen will be In order to install the torsion coil springs, it is necessary to increase the space between the windows, which reduces the area of the glass part of the window shoji, resulting in insufficient light, or the gap between the outer frame of the window and the vertical line of the shoji. There was also the problem that the width between the window and the stile became large, spoiling the appearance of the window. On the other hand, if a straight spring is used in a smoke exhaust window instead of just a ventilation window, its operating efficiency is not good, and the narrow, curved spring bodies are always exposed near the vertical frames on the left and right sides of the window. This may cause problems such as spoiling the appearance of the building. In addition, the spring of the third conventional example uses an unequal pitch coil spring, and its action is special, and due to the nature of the coil spring, its cross section is circular, and as in the above two examples, Since it is difficult to make it compact, it is not suitable for the design purpose of narrowing the width of the facing surface.

The purpose of this invention is to quickly and reliably open the smoke exhaust window within a limited time and with good cushioning properties in metal sash windows made of extruded aluminum alloy. At the same time, by narrowing the width of the facing surface, the area of the glass part of the shoji is expanded,
To provide a smoke exhaust window with a kick-out arm that has an excellent appearance that can fully correspond to the style of modern architecture that tends to provide sufficient light.

(Structure of the invention, means for solving problems) The structure of the invention will be described below with reference to embodiments shown in the drawings. In the side view shown in Fig. 1a and the plan view shown in Figs. 1b and 1c, A indicates the arm, 1, 2 of the shoji of the smoke exhaust window, which is the main part of the embodiment of the present invention.
are a pair of supports placed at both ends of arm A,
Both blocks are made of a metal material such as aluminum alloy, gunmetal, stainless steel, etc., with holes drilled into them, and support the arm spring and the regulating member, which will be described later. 3a and 3b are supports 1 and 2, respectively.
A pivot hole and a pivot hole are drilled at the ends of the pivot hole 3b, and depending on the case, the holes may be opened in opposite positions on the left and right sides, and both may be made into the pivot hole 3b. Reference numeral 5 is basically a spring end holding hole which is bored into the inside of the support from the end face 4 on the opposite side to the pivot holes 3a and 3b of the supports 1 and 2, and accommodates both ends of the arm-cum-spring described later. However, depending on the case, the lower part may be opened to form a gate-shaped hole, or the support may be formed by bending a thin metal plate. Reference numeral 6 denotes a support stand for a regulating member 10, which will be described later, which is erected on the upper part of the support members 1 and 2 near the end surface 4, and 7 is a horizontal hole drilled into the support stands 1 and 2.
0 through each end. Reference numeral 8 denotes a spring that also serves as an arm, and its both ends are pushed into the spring end holding holes 5 of the supports 1 and 2, respectively, to hold the center line in a straight line. The arm spring 8 is made by placing an appropriate wire-like narrow spring material within the thickness of the narrow supports 1 and 2.
It is formed into a continuous waveform (corrugate shape) from top to bottom. Therefore, since the bent portion of each corrugated portion has a rounded arc shape, the load is evenly distributed, and the spring has a property that it is less likely to break than a normal spiral spring. The cross section thereof may be either circular or rectangular, and the spring body is formed as a bent wire or ribbon-like spring body as a whole. Next, 9 is a stopper inserted into the spring end holding hole 5 from one side of the support body 2, and 9a is a fastening recess in the spring end 8a of the spring 8 that also serves as an arm, so that the spring can be held from the end face 4 of the support body 2. With the bent part of the spring end 8a inserted into the end holding hole 5 exposed in the fastening recess 9a, insert the square eye-shaped catch 9 from one side and attach the spring end 8a to the support body 2. Attach.
The clasp 9 may be a rectangular protrusion or the like that is integral with the support body and protrudes from the end, and the clasp 9 may be hooked by pushing the curved portion of the spring end 8a. Reference numeral 10 denotes a regulating member which is loosely inserted into the horizontal hole 7 of the support base 6 of each of the supports 1 and 2, and has a fastening fitting 11 fixed to the end thereof, and is made of a wire made of a large number of twisted steel wires of small diameter. A strong, small-diameter steel rod is used, and the fastening fittings 11 are firmly crimped, welded, etc. so that they will not easily break or come off even if subjected to impact when the window shoji C is opened. Alternatively, in the case of a steel rod, the opening angle of the window can be changed depending on the screwing position by cutting a female thread on a steel rod with an appropriate male thread of length or shortness and screwing it. The regulating member 10 as a whole is formed as a rod-shaped body having a narrow diameter that matches the narrow thickness of the above-mentioned narrow arm/spring 8, and both of them are formed to have a narrow and thin shape as a whole. Next, Fig. 2a is a side view of the main parts of an example of the arm A of the present invention installed on an external window, and Fig. 2b is a partial cross-section of the arm guide 16 or 23a and the fixing plate 21 described later , is a front view with window shoji C and window frame B omitted, O is the outside of the building, I is the inside of the building, and in both cases, 12 is fixed to the opening of the building frame The vertical frame C of the outer frame B of the window is the above-mentioned window shoji whose lower stile is pivoted by hinges etc. 14 near both sides of the lower part of the lower frame 13 in the case of the outer frame B of the window. Alternatively, it may be pivoted at a stile facing the upper frame of the outer frame B (not shown). 15 is window shoji C
At the vertical stile on both sides of , arm A spans between the outer frame B and the stile of window shoji C. Reference numeral 16 denotes an arm guide fixed to the outside of the vertical frame 15 on both sides of the window shoji C by screwing or spot welding. A single plate fixing piece 16a is attached to both ends of the casing. 1
Reference numeral 7 denotes a long guide groove formed in the longitudinal direction on the narrow upper surface of the arm guide 16;
The sliding pin 18 is attached to the pivot hole 3b of the window sash C, and the retainer 19 is fixed to the rear projection of the long guide groove 17, so that the sliding pin 18 slides inside the long guide groove 17 along the longitudinal direction of the window sash C Mount it so that it can move. Reference numeral 20 denotes a stopper made of an elastic cushioning material made of synthetic rubber material, semi-rigid foamed urethane material, etc., attached to the lower part of the arm guide 16. In order to improve the cushioning performance, a plurality of sections may be circular or circular in cross section as necessary. Oval horizontal hole 2
Leave 0a open. Thus, by changing the length of the stopper 20, it is possible to change the opening angle of the window sash C. Additionally, this stopper 20 may also be attached to the upper part of the arm guide 16 if necessary. 21 is the pivot hole 3a of the support body 1 of arm A
This is a fixed plate that is pivotally supported by a pivot pin 22.The end of the support body 1 is placed on the outer surface of the middle and high part with a cross section of a square shape with a middle height, and the pivot pin 22 is inserted from the back side to support the tip part. By fixing the arm A in the pivot hole 3a of the body 1 and further fixing the fixing plate 21 to the vertical frame 12 using the fixing piece 21a, the arm A can be attached to the vertical frame 12 at the position of the pivot pin 22. However, it can be rotated freely. Next, FIG. 3 is a side view of the main part of an example in which the arm A of the embodiment of the present invention shown in FIGS. On the inside of the building, in the figure, 18a is a sliding body made of hard synthetic resin or metal material on which a sliding pin 18 is mounted, and the side part 18b is a vertical frame. Guide long groove 23a of 12 arm guides 23
It engages and slides up and down. In this case, sliding pin 1
8 essentially acts as a pivot pin. In addition, although the other parts are the same as the outward folding window, the stopper 20 may be either a block body as shown in the figure or one with an oval horizontal hole as shown in FIGS. 2a and 2b. In addition, the materials are also different. Next, FIG. 4 shows an example of a closing mechanism D applied to an outward folding window that is closed by a manual operating wire W.
The guide roller 24 is an operating handle, and in the case shown, it simultaneously releases the locking claws of the window shoji C (not shown) and moves the window shoji from the compressed state of the spring 8 which also serves as an arm. The window shoji C is quickly opened by the repulsion force to the stretched state and the gravity based on the own weight of the window shoji C to adapt to the smoke evacuation work, and when the window shoji is closed, the handle 24 is rotated to roll it up. By winding up the operation wire W around the drum of the shaft, the fixed window shoji C is closed at the same time as the window shoji and the guiding roller, the ends of which are fixed.
In this case, the stopper 20 satisfactorily absorbs the sudden opening of the window sash and the impact due to its weight, so the frame and glass of the window sash will not be damaged.

(Function) The function of the embodiment of the present invention having the above-mentioned partial configuration will be explained in the case of an outward-folding window. When the engaging claws of the window shoji C that were engaged with the latching portions of the outer frame B of the window (not shown) are released, the arm spring 8 of the arm A shown in FIG. , from the closed state of the window sash C shown in FIG. 5a, the window sash C shown in FIG. The pin 18 is still near the upper end 17a of the long guide groove 17, but the fastening metal fittings 11 that regulate the maximum extension position of the arm spring 8 fixed to both ends of the regulating member 10 are closed when the window shoji C is closed. The supports 1 and 2 were separated from the support base 6 in the above, but as the arm spring 8 expands, they approach each other, and when the two are connected, the arm spring 8 restricts further extension of both. Regulating member 1
0 and the arm-combining spring 8 will serve only as an arm from now on. In addition, the spring 8 that also serves as an arm
The extension of C is carried out in a short time depending on the restoring force of the compressed spring, but when the sliding pin 18 reaches the lower end 17b of the guide long groove 17, the window sill C
The weight of the arm guide 16 and the impact caused by the sudden stop of the high-speed opening are applied to the stopper 20 at the end of the arm guide 16. Contrary to the above, for example, when closing the window shoji C against the outer frame B using the closing mechanism D of the window shoji C shown in FIG. are the support base 6 of the supports 1 and 2 and the regulating member 10
The fastening metal fittings 11 fixed to both ends of the frame are in a joined state, but as the position in FIG. In addition, in the case shown in the figure, supports 1 and 2
Although the fastening metal fittings 11 are shown spaced evenly apart from each other, depending on the case, they may be unevenly spaced.
1 is fixed by welding or the like, separation between the two occurs only between the upper fastening metal fitting 11 and the support base 6 of the support body 2. In addition, when closing the window sash C using the wire W shown in FIG. 4, the guide roller R fixed to the window sash C, the outer frame B, and other wall bodies etc. are removed by rotating the operating handle 24. The wire W receives the operating force accompanying the closing operation of the window sash C by the guide roller R disposed in the window sash C, compressing the arm spring and closing the window sash C. In addition, in the case of the inward-folding window shown in FIG. 3, the operation is the same as that of the outward-folding window shown in FIG. 2a, except that the window shoji C opens toward the inside of the building.

(Effect of the invention) Since the present invention has the above structure and function, the opening angle of the window sash C can be changed depending on the dimension between the fastening fittings 11 at both ends of the regulating member 10 or the dimension of the stopper. If the elastic force is constant, select the length of the arm spring 8, and if the spring length is constant, select a spring with a different elastic force, or change the effective dimension of the regulating member 10. By moving the fastening fittings 11, it is possible to freely adjust the kicking force of the window shoji C. In addition, since the arm spring 8 of the other arm A is equipped with the regulating member 10, compared to a conventional straight spring only,
The direction of its operation is accurate and it expands and contracts stably, and
When opening and closing the window, the arm A is neatly stored between the outside of the vertical stile of the window shoji C and the vertical frame 12 of the window frame B, except when opened to exhaust smoke in an emergency. Since you can't see it, you can see that it's clean and nice from an interior perspective. Therefore, according to the present invention, the number of constituent parts is small, the structure is relatively simple, and it can be installed and applied to both types of windows that tilt outward and windows that tilt inward. Therefore, in terms of product production, it is advantageous in that costs can be rationalized, and stoppers made of simple materials and structures have excellent functionality compared to stoppers with small holes that have complicated structures and are troublesome to produce and assemble. While it is not inferior to an air damper consisting of a cylinder with a piston inside, it is so cheap that it is not a problem in terms of price, and it is also highly durable. Furthermore, the arm of the smoke evacuation window with a kick-out arm of the present invention has a pair of narrow supports 1 and 2 arranged at both ends.
Then, the both ends are attached to the narrow supports 1 and 2, the center line is held in a straight line, and the narrow width is bent up and down within the narrow thickness of the narrow supports 1 and 2. An arm spring made of corrugated spring material and a rod-shaped arm spring whose center line is held in a straight line are arranged side by side on one longitudinal side of the arm spring and whose ends are loosely fitted to the supports 1 and 2. The regulating member is formed to have a narrow and thin shape as a whole. Therefore, according to the present invention, it is possible to narrow the gap between the outer frame of the window to which the kick-out arm is attached and the vertical stile of the shoji screen. The glass area of the shoji can be increased,
In addition to being advantageous in terms of lighting, the narrow width of the opening surface also provides the advantage of providing a smoke exhaust window with a kick-out arm that has a good appearance in terms of window design.
