Abstract

[PROBLEMS] To provide a safety device that enables safety and quick escape of residents in an emergency in a three-story or higher building.
A semi-circular fan framed in spring-like metal is installed in a building in a closed state, switched on in the event of an emergency such as a fire, and a motor 13 is activated to remove the fan's fasteners. By fully opening the fan with force and sticking it to the magnet attached to the outer wall, residents will not feel afraid of heights, stand on the fan, connect ladders and descend from fan to fan one after another, high-rise building It was made possible to escape from quickly. Also, even if the ladder can't be used, fans can help.

Description

  The present invention relates to a fan-shaped safety device attached to the lower side of an outer wall window of a three-story or higher building.

  Conventionally, in the event of an emergency such as a fire in a high-rise building, if the elevator or stairs become unavailable, the residents will panic and jump directly from the window and hit the ground, resulting in serious injury or death. Examples have been seen many times in the past. In the future, the number of high-rise buildings in the city will increase, and there are concerns that similar accidents will increase.

The ladders of conventional emergency escape devices are usually installed behind the corners of the veranda, but if you are caught in smoke by fire, it is difficult to reach the ladder and use it calmly.
Because of fear of heights, it is often impossible to use it. Panic and fear of heights are challenges to overcome. Therefore, in a place where you can get assistance from fire trucks and people on the main street, such as the main street, install a device that quickly escapes without feeling so much fear of altitude, and tries to solve the disadvantages of past escape methods. To do.

  The present invention uses a fan shape as a hint to make a fan-shaped light metal or non-flammable chemical compound as a semi-circular material, and the fan that is fully opened by a powerful spring is closed. It is to be installed below the window on the outer wall of each floor. In an emergency, the residents get out of the windows and ride on the fan that is fully open, and then get down from the hole in the center of the fan through the ladder installed on the outer wall. By increasing the size of the fan as you go down, you can jump from fan to fan even if the ladder is not available. The impact of falling from high places is alleviated each time. The disadvantages of conventional escape methods are solved by the advantages such as less fear of heights, resting on the way of each fan, and the ease of falling shock in the event of a ladder failure.

  By installing the above-mentioned fans on each floor or on several floors, people who live in high-rise buildings can alleviate daily anxiety about emergencies. In addition, people who are rescued by fire trucks can easily work with cranes, making escape safer and faster.

Best mode for carrying out the invention

留め、金属粋は磁石により外壁に取り付けた別の金属板二枚それぞれに固定する。ファンの留めの金属枠には、強靭な金属線を付け、モーターに巻きつかせる。外壁のごく近い場所にモーターを設置し、スイッチで電流が流れるとモーターが回り、金属線を引っ張るので金属枠は外れ、ファンが開く。
ファンが固定されている側の反対側には強力な磁石を取り付けた金属板が外壁に設置されており、ばねの力でファンが勢いよく開いたとき、磁力によってさらにその金属板に引き付けられ密着する。また、密着部のやや下方の外壁に、ファンの受け台となる金属台が取り付けられており、表面にぶ厚いゴム板を付けたその台が密着部を支える。さらにファンの中心部の縁近くに二本、磁石に密着する部分の縁近くに二本、合計四本の強靭な金属線が付いており、あらかじめ外壁に設置した別の金属板にそれぞれの先端部が固定されているので、ファンの全開時にその水平がほぼ定まり、ファン全体の強度が増す。Close the semi-circular fan with a strong spring at the center, stick it in the shape of a rod, and place it on the outer wall of each floor.

Fasten and fix the metal on each of two other metal plates attached to the outer wall with magnets. Attach a strong metal wire to the metal frame of the fan, and wrap it around the motor. A motor is installed very close to the outer wall. When a current flows through the switch, the motor turns and pulls the metal wire, so the metal frame comes off and the fan opens.
On the opposite side of the side where the fan is fixed, a metal plate with a strong magnet is installed on the outer wall, and when the fan opens vigorously by the force of the spring, it is further attracted to the metal plate by the magnetic force. To do. In addition, a metal base serving as a cradle for the fan is attached to the outer wall slightly below the close contact portion, and the base with a thick rubber plate on the surface supports the close contact portion. In addition, two strong metal wires, two near the edge of the center of the fan and two near the edge of the part that is in close contact with the magnet, are attached to separate metal plates installed on the outer wall in advance. Since the part is fixed, the level of the fan is almost fixed when the fan is fully opened, and the strength of the entire fan is increased.

Hereinafter, an embodiment will be described with reference to the accompanying drawings. Reference numeral 1 is a light metal or a fan (fan) body formed in a semicircular shape by an appropriate material such as a non-flammable chemical compound, and 1a and 1b are metal pieces having a toughness attached to the body.
1c, 1d The first solid line and the wavy line aligned therewith are folding mountains. The folded mountain portion is made of a thin and strong metal wire. The equal angle is 22.5 degrees from the solid line to the solid line, and only 10 degrees near the wall. The reason for the 10 degree portion is that when the fan is fully opened, there is a margin in length so that it reaches the outer wall portion with the magnet attached. Depending on the material, the angle should be smaller.
2 is a fixed part to the outer wall, and the material is a strong metal. The angle is 22.5 degrees, and it is folded in half at the fold mountain beforehand and used in double. 2a and other circular holes are for fixing screws, and are fixed to the metal plate installed on the outer wall with screws. 2b is a thin and strong metal spring, and a 2c portion at the tip is fixed to 2. The opposite 2d portion hangs down in the air with the entire spring when the fan is fully opened.
Reference numeral 3 denotes a portion to be brought into close contact with a metal plate installed on the outer wall when the fan is fully opened. The size and the angle are the same as 2; A strong magnet is attached to the metal plate on the outer wall. Alternatively, the entire plate is a magnet. Reference numerals 4, 5, 6, and 7 denote metal wires slightly inward from the circular edge of the fan, and the portions 4a, 5a, 6a, and 7a are fixed to a metal plate that is installed on the outer wall in advance. 7 has three magnet portions 7b, 7c and 7d. The entire fan is normally installed in the shape of a folded bar on the outer wall of each floor. For the color, the smart part is the same color as the outer wall, and the open part is white or light green.

  Reference numeral 8 denotes a fastener that keeps the fan body in a folded state. The portions 8a and 8b are magnets that are attracted to and closely contact the metal plates 9 and 10 attached to the outer wall. The metal wires 4, 5, 6, and 7 are gathered at one end 4 a, 5 a, 6 a, and 7 a and fixed in advance to a metal plate attached to the outer wall. In an emergency, when the switch 12 is turned on, current flows, the metal wire 14 wound around the motor 13 is pulled with a strong force, the 8 fasteners come off, and it catches on the 15 frame attached to the outer wall. The fan is suddenly opened by the spring force of 2d at the tip and the bridge spring force of the fan body, and is attracted to the metal plate 17 having a magnet attached to the opposite outer wall, and the portion 3 is brought into close contact. At that time, the cradle 18 with a rubber plate supports the contact portion. 7 is also in close contact with the magnet portions 17a, 17b and 17c on the outer wall.

  When the fans on each floor are confirmed to open, switch off and stop the motor operation. Switches are installed as appropriate on the first floor outer wall, inside and outside each floor. Residents escape outside through the window, stand on the fan, and descend from the hole 16 through a ladder installed on the outer wall. The device is preferably located on the outer wall facing the road where the fire engine can enter. During normal times, the ladder on the first floor is covered with a fence and cannot be used. Inspect all magnets and other equipment regularly.
