Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a door device installed outside a window for the purpose of crime prevention.
[0002]
[Prior art]
Aluminum sashes are mostly used for windows in ordinary houses, but aluminum sashes have extremely low crime prevention properties that can be easily invaded by suspicious people if the crescent is destroyed. It is unthinkable in foreign countries that no security measures are taken on such aluminum sash windows.
[0003]
On the other hand, in apartment houses such as condominiums, there are many cases where aluminum sashes are protected from the outside by a face lattice or the like. In such a building, when there is a fire, there are face lattices etc., so it is impossible to escape from the window, and there are many people who are late to escape and are victims of the fire.
[0004]
[Problems to be solved by the invention]
The present invention has been made in view of the circumstances as described above, and it is an object of the present invention to provide a door device that can be instantly opened in the event of a fire while having high crime prevention properties and that can easily fix the opened door. And
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a door device of the present invention is provided with two left and right door bodies that open and close like a double door between upper and lower frame members fixed to the outside of a window, and the door body is a door of the frame material. Locked in a closed state by a door stopper provided on the back of the body and a lock pin provided on the back side of the door of the frame material and outside the support shaft of the door so as to be freely inserted and removed. The door body can be opened to the outside, and when the lock pin is inserted in the same position as when closed, the door body is sandwiched and fixed between the side end surface of the door stop and the lock pin. To do. The door stop and the lock pin may be provided on both the upper and lower frame members, but may be provided on only one of them.
[0006]
The door device of the present invention having the above-described configuration is capable of reliably preventing the intrusion of a suspicious person because the lock pin that locks the door body in the closed state is hidden from view from the outside of the door body. The door can be opened instantly by pulling out the lock pin. Moreover, since the door body can be fixed in the open state by inserting the pulled lock pin into the same position, it is convenient even when it is desired to open it occasionally in daily life.
[0007]
Further, the invention according to claim 2 is characterized in that, in addition to the above requirements, an escape rope is accommodated in the door body. According to the present invention, when a fire breaks out, the evacuation rope is taken out from the door body, the door body is opened, and the evacuation rope is hung on the upper frame material and hung down, so that evacuation can be performed from the second floor or the third floor. .
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 to 3 show an embodiment of a door device according to the present invention. This door device is provided on the outdoor side of the aluminum sash 1, and the upper frame member 2 and the lower frame member 3 are installed in parallel to the outdoor side by a bracket 9 fixed to the wall surface. 2 and left and right door bodies 4 and 4 that pivot on the lower frame member 3 and open and close like a double door.
[0009]
The door body 4 is a metal plate formed by processing an iron plate, and is made lighter by making a square punched hole 10 over the entire surface. The lower support shaft 6a that supports the door body is fixed to the lower frame member 3, and the upper support shaft 6b is urged by a spring (not shown) on the upper portion of the door body so that it can protrude from the door body 4. It is provided. When the door body 4 is first assembled between the upper and lower frame members, the lower support shaft 6a is inserted into a hole formed in the lower surface of the door body 4, and the door body 4 is then retracted with the upper support shaft 6b retracted. Standing vertically, the upper support shaft 6 b is inserted into the hole 11 of the upper frame member 2.
[0010]
In addition, a hollow reinforcing member 12 is laid horizontally on the back surface side of the door body 4, and an evacuation rope 8 is accommodated in the hollow portion of the reinforcing member 12 of either the left or right door body. . The rope has a take-out end 13 formed in a ring in a take-out hole 13 formed on the side surface of the reinforcing member 12 so that it can be easily pulled out of the room when a fire occurs. The pulled out rope 8 is fixed firmly by hooking the looped tip 14 onto the upper frame material 2 and passing the other tip through the ring, so that it can be easily evacuated from the window. it can.
[0011]
The upper frame member 2 and the lower frame member 3 have a door stop portion 5 that abuts on the back side of the door body 4, so that the door body 4 does not rotate toward the window side. Further, both sides of the upper surface of the lower frame member 3 have lock pins 7 that can be freely inserted and removed. If the lock pins 7 are inserted with the door closed, as shown in FIG. The pin 7 is in contact with the outer side of the support shaft 6a on the back side of the door body, and is locked so that the door body 4 does not rotate neither on the outdoor side nor on the window side. When the lock pin 7 is pulled out from the lower frame member 3, as shown in FIG. 3 (b), the door body 4 can be rotated toward the outdoor side, and the door body is opened in the same hole with 90 degrees open. When the lock pin 7 is inserted again, as shown in FIG. 3C, the door body 4 is sandwiched between the lock pin 7 and the side end surface of the door stop portion 5, and the door body 4 is fixed in an open state. The lock pin 7 has a prismatic portion protruding from the lower frame material 3 so that the door can be reliably locked by hitting the door 4 with a surface and can be easily inserted and removed. As described above, the door device can lock the door body 4 between the closed state and the open state by a simple mechanism using one lock pin 7. In the closed state, the lock pin 7 cannot be seen from the outside, and since it has a new structure that has never been seen before, the risk of being broken by a suspicious person is low.
[0012]
The door device of the present invention is not limited to the embodiment described here. It may be a mode in which crime prevention is not the primary purpose, for example, to prevent a person from falling from a window or to block the line of sight from the outside. change. If there is no need to open the door body, the lock pin may be fixed with a set screw so as not to come off.
[0013]
【The invention's effect】
As described above, in the door device of the present invention, the lock pin that locks the door body in the closed state is hidden from view from the outside of the door body so that it can be reliably prevented from entering the suspicious person. The door can be opened instantly by pulling out the lock pin. Moreover, since the door body can be fixed in the open state by inserting the extracted lock pin into the same position, it is convenient and highly useful when it is desired to open it occasionally in daily life. Moreover, since the structure is simple, it can be provided at low cost.
[0014]
Furthermore, as described in claim 2, by storing the evacuation rope in the door body, when the fire breaks out, the evacuation rope is taken out from the door body to open the door body, and the evacuation rope is used as the upper frame material. You can evacuate from the 2nd floor, 3rd floor, etc.
