Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency exit window structure in which a handrail provided with a lock device that can be released in an emergency and a shoji screen that allows ventilation and daylight are provided in parallel.

[0002]

2. Description of the Related Art When installing an opening window on the third floor as a fall prevention measure for buildings, it is necessary to construct the opening window at a position 800 mm or more from the window stand and 1100 mm or more from the floor surface. It is stipulated (internal regulations for industrialized housing environmental performance operation). Therefore, the conventional opening window is shown in FIG.
When the circular opening window 2 or the pentagonal opening window 3 is installed on the roof gable 1 as shown in (B), the opening window must be installed in consideration of this point.

[0003]

However, the circular opening window 2 or the pentagonal opening window 3 is formed in the roof gable surface 1 as in the above-mentioned conventional case.
When installing a building, there is a problem that the opening window cannot be installed in a building in which the height from the floor surface to the window sill cannot reach the above-mentioned specified dimension. There was also a problem that the floor plan had to be changed for that reason.

The emergency exit window structure according to the present invention is a completely new technology developed in view of the above-mentioned conventional problems.
In particular, by providing a handrail provided with a lock device that can be released in an emergency in parallel with the draft-screening door for ventilation, it is possible to prevent falling, ventilation, daylighting, and an emergency entrance for emergencies. It provides a completely new technology for emergency exit window structures.

[0005]

The window structure for an emergency exit according to the present invention is a technique which has fundamentally improved the above-mentioned conventional problems, and the gist thereof is to remove or collapse it by releasing the locking device. The window structure for an emergency exit is characterized in that it is provided in the opening side by side with a handrail that allows ventilation to be arranged in parallel.

[0006]

The function of the emergency exit window structure according to the present invention is as described above.
Since the handrail is provided in parallel with the shoji screen, ventilation and daylight can be taken into the room, and the fall of the infant can be prevented. Further, in the window structure of the present invention, the handrail is provided with the lock device, and the handrail can be removed or collapsed by releasing the lock device of the handrail, so that the lock device is released in an emergency. The handrail can be removed or knocked down, and firefighters etc. can enter from this part. Therefore, it can be easily installed as the opening window of the substitute entrance even in a narrow place where the height of the roof gable surface or the height from the window stand is in conflict with the internal rule as described above.

1 is a perspective view of an emergency exit window structure according to the present invention, and FIG. 2 shows a state in which a handrail is removed. FIG. 3 is a perspective explanatory view, FIG. 3 is a cross-sectional explanatory view showing a lock device provided on a handrail, FIG. 4 is a perspective explanatory view showing an emergency exit window structure of another example, and FIGS. FIG. 6 is a perspective explanatory view showing a lock device, and FIG. 6 is a perspective explanatory view showing a handrail of another example.

In FIGS. 1 to 3, reference numeral 10 denotes a handrail, which is detachably attached to the interior side of the emergency exit opening 11. This handrail 10 has an upper horizontal shaft 12 and a lower horizontal shaft 13.
And a plurality of handrails 14 arranged in parallel between them. The handrail 10 is detachably mounted via a mounting bracket 15 provided in the emergency opening 11.

That is, both ends of the upper and lower horizontal joints 12, 13 are fitted from above into the mounting fittings 15 provided on the upper and lower sides of the emergency exit opening 11, and both end portions of the upper horizontal joint 12 and A vertical pin hole 16 is formed in each of the mounting brackets 15 that support the both ends.
By inserting the pin 17 into the inside 6, the upper lateral joint 12 can be fixed to the mounting member 15. Further, the lower end portion of the pin 17 has a size capable of protruding from the lower surface of the mounting member 15, and a ring groove 18 is bored in the lower end portion of the pin 17. Reference numeral 19 denotes a bracket piece having an L-section, and two horizontal cut grooves 20 into which the pin 17 can be inserted are formed in the horizontal piece along the ring groove 18 of the pin 17. There is.

Therefore, particularly when the bracket piece 19 is deeply slid along the ring groove 18 of the pin 17 to the lower surface of the upper horizontal shaft 12 as shown in FIG.
The cut groove 20 and the ring groove 18 of the pin 17 are engaged with each other so that the handrail 10 can be completely locked. Next, when the lock 10 is released and the handrail 10 is deleted, the bracket piece 19 is pulled out along the lower surface of the upper horizontal shaft 12 as shown in FIGS. The engagement between the groove 20 and the ring groove 18 of the pin 17 is released so that the handrail 10 can be lifted upward and removed from the emergency opening.

In the figure, 21 is a window sill, 22 is a wall, and 23 is a skirting board provided between the wall 22 and the floor 24. Further, a glass shoji (not shown) capable of ventilation and daylight is provided in parallel to the handrail 10 on the outdoor side of the emergency opening 11.

In the above embodiment, the handrail 10 is completely removed to the outside of the emergency opening opening 11. However, as shown in FIG. 4, for example, the handrail 10a is tilted toward the inside of the room to open the emergency opening. It is also possible to open the opening 11 for use. The handrail 10a shown in FIG.
Both ends of the lower joint 13 of the shaft 0a are rotatably attached to the mounting member 15a so that the lower joint 13 can be tilted toward the inside of the room by using the lower joint 13 as a spindle. Also, the handrail 10
Both ends of the upper shell 12a are configured to be locked to the mounting fitting 15b via the pins 17a, respectively.

In the above embodiment, the pins 17, 17a are
Are inserted into the pin holes 16 from above both ends of the upper casing 12 of the handrails 10 and 10a.
0a can be locked to the mounting brackets 15 and 15b, but as shown in FIGS. 5 (A) and 5 (B), the pin 17b,
17c along the lower surface of both ends of the upper shell 12
It is also possible to lock the handrails 10 and 10a by inserting them into the pin holes 16 of c and 15d from the horizontal direction.

In particular, in the case of FIG. 5 (B), a projection 25 is provided on the pin 17c so that the projection 25 has a pin hole 16a.
It is configured so as to be able to engage with a groove (not shown) formed in the above, and the lock cannot be released unless the pin 17c is pulled while rotating. Further, as shown in FIG. 6, the handrail 10 has a transparent or translucent acrylic plate 26.
It is also possible to configure the handrail 10b in which one side is stretched. The lock device may be configured so that when it is released, a switch is turned on and a signal such as an alarm is output.

[0015]

Since the emergency exit window structure according to the present invention has the above-described structure and operation, it has the following effects.

(1) Even in a narrow space such as the roof of the roof, it is possible to easily install an opening window that allows daylight and ventilation without changing the layout or the like. (2) Since the handrail provided with the lock device is provided inside the opening in parallel with the shoji, there is no fear of falling of an infant or the like. (3) In an emergency, by releasing the locking device, the handrail can be easily removed or tilted to open the emergency exit opening, and the emergency exit opening can be used as an entrance for firefighters. (4) The entire structure is simple, and it is possible to easily assemble and configure on-site parts that are manufactured in advance in a factory or the like.
