Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a building evacuation device that is installed on each floor of a building with two or more floors, such as an apartment complex, and is used to evacuate to a safe location downstairs in an emergency.

Conventional evacuation devices of this type include those in which an opening is formed in the wall of each floor to serve as an emergency exit, and an evacuation platform with built-in evacuation equipment such as a slide or ladder is rotatably stored in the emergency exit;
A system has been proposed in which an evacuation platform is slidably inserted into the floor near the emergency exit and is pulled out together with the emergency door.

However, since such evacuation devices form openings in the walls of buildings or form storage areas for evacuation platforms,
Installation is troublesome and requires extensive construction, making it particularly unsuitable for installation in an existing building.

Furthermore, even when such evacuation equipment is not in use, it is necessary to leave a large space in the vicinity of the emergency area, so the living space inside the building cannot be used effectively, and furthermore, in the event of an emergency such as a fire, There was a risk that the evacuation equipment would not be able to be operated properly due to the smoke and other obstacles.

In view of this, the present invention makes use of the space under the Veeranda floorboards that protrude from each floor of the building, and by suspending the evacuation platform with guide rails, it can be easily installed in new and existing buildings, and it can be installed safely and quickly. The purpose is to enable evacuation.

To explain the configuration of the present invention in detail with reference to the embodiments shown in the attached drawings, the evacuation devices are installed on the lower surface of the Veeranda floorboard A on each floor of a building with two or more floors so that each evacuation device is almost in a straight line. A pair of guide rails D is suspended and fixed to the lower surface of the Veeranda floorboard A by a fixture G, an evacuation platform C is slidably engaged and suspended between the pair of guide rails 0, and this evacuation platform It consists of a telescopic evacuation device E built into the evacuation platform C, and an enclosure F erected at least on the tip side of the evacuation platform C.

A pair of guide rails D, which slidably suspend the evacuation platform C on the lower surface of the Veeranda floorboard A, are suspended and fixed in parallel to the lower surface of the Veeranda floorboard A by means of fixtures G that are installed separately or integrally on the outside of the guide rails. The evacuation platform C is equipped with a pair of guide wheels 1a and 1b provided between the pair of guide rails D at the rear of both sides of the evacuation platform C, so that the evacuation platform C can move along the guide rails D. It slides forward and protrudes forward of the Veeranda floorboard A.

As shown in Fig. 1, the evacuation equipment E provided on the evacuation platform C is constructed by connecting a plurality of hollow sliding rods 3 each having a different diameter and having a step board 2 at the lower end in a telescopic manner. The upper hollow sliding rod 3 is rotatably supported on the inner wall of a hole 4 provided in the evacuation platform C, and when not in use, each hollow sliding rod 3 is compressed into a collective shape, and the hole 4 is closed. At the same time, the upper side of the hole 4 is closed with the cover body 5, and the evacuation platform C is stored on the underside of the Veeranda floorboard A together with the evacuation platform C, and when the shelter is used, the evacuation platform C on each floor is moved toward the front of the Veeranda floorboard A. Along with sliding protrusion,
The evacuation equipment E built into the evacuation platform C is extended downward to reach the vicinity of the evacuation platform C on the lower floor.

When installing this evacuation equipment E on the evacuation platform C on each floor, as shown in Figure 1, the evacuation equipment E on the upper and lower floors should be installed alternately to the left and right sides of the evacuation platform C so that they do not overlap each other. This is a heated argument.

In addition, the evacuation equipment E may be one that uses various types of extendable ladders such as link ladders, chain ladders, rope ladders, extendable or foldable stairs, or even vertical evacuation bags.

The enclosure F formed on the evacuation platform C is constructed by fixing a plurality of vertical bars 6 to the front side of the evacuation platform C and providing a horizontal bar 7 at the upper end thereof, as shown in the first figure. When not in use, the fence 8 is stored in an upright state close to the Veeranda handrail B as shown in Figure 2, and when in use, it is stored in the upright position as shown in Figure 1. Evacuation platform C with sliding protrusion as shown
An enclosure F is formed by a fence 8 erected on the front side of the evacuee, and when an evacuee climbs over the Veeranda handrail B and moves to the evacuation platform C, the momentum causes the evacuee to move from the front side of the evacuation platform C. Prevents you from falling.

In addition, both sides of the evacuation platform C are secured by a ladder-type evacuation device E hanging down from the upper floor on the negative side, and the lid body 5 provided on the evacuation platform C is opened and fixed approximately vertically on the other side. By doing so, each of them is shielded.

Although the above-mentioned fence 8 was explained as being in the form of a vertical lattice, metal plates,
The blinds may be made of an inorganic board, etc. In this case, when in use, the front side is completely blindfolded, further alleviating fear during evacuation. It can also be used as a blindfold panel.

Furthermore, although the fence 8 forming the enclosure F has been described as being stored parallel to the front side of the Veeranda handrail B, as shown in FIGS. When not in use, the fence 8 is fitted into the opening 9 to form a part of the Veeranda handrail B, as shown in Figure 4. 5 As shown in Figure 5, it is also possible to make the evacuation platform C protrude forward and form an enclosure F with the fence 8.
There is no need to manufacture the railing 8 and the fence 8 separately, thereby reducing the manufacturing cost, and also allowing easy access through the opening 9 of the Veeranda handrail B when in use.

In the previous explanation, a fence 8 was provided only on the front side of the evacuation platform C to form an enclosure F, but as shown in Figure 6, a part of the Veeranda handrail B is cut out to form an open part 9. A door body 10 made of the same material as the Veeranda handrail B is rotatably attached to the opening part 9, and when not in use, the opening part 9 is closed and locked (as shown by the two-dot chain line). (not shown) to form a continuous Veeranda handrail B, and when using the straw, the evacuation platform C is projected forward, and the door body 10 is unlocked and rotated toward the evacuation platform C side. , is locked by a stopper 11 provided on a fence 8 erected on the front side of the evacuation platform C, and an enclosure F is formed by this fence 8 and the door body 10.

The □ body 10 is provided so as to rotate toward the evacuation equipment E side, which is biased to one side of the evacuation platform C, and to shield -fUU of the evacuation platform C.

Furthermore, as shown in Figures 7 and 8, Veeranda Handrail B
is cut out to match the width of the evacuation platform C to form an open part 9, and two door bodies 10, 10 made of the same material as the Veeranda handrail B are rotatably attached to both ends of the open part 9. At the same time, the tip side of each door body 10 is connected to the guide groove 12 provided in the evacuation platform C.
When in use, the evacuation platform C slides and protrudes at the same time as the door body 10°1.
0 can be rotated to form an enclosure F with the door bodies 10, 10 and the fence 8 provided on the front side of the evacuation platform C, especially the door on the side from which the evacuation equipment E on the upper floor hangs. The body 10 also functions as a stopper and can alleviate the swinging when an evacuation device such as a rope ladder that swings violently when going up and down is used.

This door body 10 is made up of two members 14 as shown in Figure 9.
．． It is also possible to pivotally attach the tip of the door body 10, which is foldably connected to the evacuation platform C, in this case, the guide groove 12 as shown in FIG. Since it is a frictional resistance, it can be operated smoothly.

Further, the enclosure F is formed by erecting and fixing the fence 8 to the evacuation platform C, or is formed by the fence 8 and a door body 10 which is rotatably provided with a part of the Veeranda handrail B. As explained above, as shown in FIGS. 10 to 12, the fixed support 1
5 is fixed to the evacuation platform C, a movable column 17 is rotatably attached via a support shaft 16, and one end of a spring 18 wound around the fixed column 15 is attached to the movable column 17.
When the movable support column 17 is collapsed as shown in FIG. 11, the spring 18 is compressed, and when the evacuation platform C protrudes, the spring 18 automatically It is also possible to provide a foldable fence 8 around the evacuation platform C by allowing the movable support 17 to stand up.

As described above, the present invention comprises a pair of guide rails D suspended and fixed on the lower surface of the Veeranda floorboard A by means of fixtures G, an evacuation platform C slidably suspended between the pair of guide rails 0, and an evacuation platform C. It consists of a telescoping evacuation device E built into the stand C and an enclosure F installed at least on the tip side of the evacuation stand C, so when it is installed in a building, there is an opening in the wall or floor and the evacuation stand can be stored. It can be easily installed in an existing building by simply fixing the guide rail D to the underside of the Veeranda floorboard A without the need to form a section, and the evacuation platform C can be stored on the underside of the Veeranda floorboard A when not in use. Since it is suspended in the same state, the effective area of the Veeranda is not reduced and the Veeranda can be used effectively.Furthermore, in the event of an emergency such as a fire, the building is temporarily evacuated from inside the building to the Veeranda, so it is not exposed to smoke or flames. In addition to being able to operate the evacuation equipment reliably, the fence F installed on evacuation platform C prevents falling accidents when moving from Veeranda to evacuation platform C, alleviating the fear of evacuees and allowing them to evacuate quickly. It is something that can be done.
