Description

[Detailed explanation of the invention] This invention relates to an evacuation device in the event of a disaster such as a fire. A frame body incorporating a gear train of a reduction mechanism that meshes with the frame body is connected via a rope shaped like a ladder to a lifting platform lighter than the frame body which ascends and descends along a guide member provided outside along a hollow support column, Normally, the lifting platform is locked with a latch at the top of the hollow support, and when it is locked, an object is placed on it so that it is heavier than the frame.If the rack is removed in the event of a disaster, the lifting platform will be held at a certain level by its own weight. To provide an evacuation device that allows evacuation along a rope ladder when the elevating platform descends to the ground surface by gradually descending at a descending speed.

Conventionally, for evacuation in the event of an emergency such as a fire, rope ladders hung from windows on each floor or evacuation bags have been used.

However, in the former case, when descending, the ladder is simply suspended and the lower part is not fixed, causing the ladder to swing, which is dangerous for the elderly and children.

Moreover, the latter requires expensive equipment.

In view of these points, the present invention attempts to address and solve this problem.

An embodiment of the evacuation device according to the present invention will be described in detail below with reference to the accompanying drawings.

1 is a hollow pillar, and this hollow pillar 1 extends to each floor above the second floor so that it can be connected.
A rack 2 is vertically installed on the inner wall of the hollow support 1, and the rack 2 meshes with a gear train of a speed reduction mechanism a built into a frame 3 to reduce the speed.

Suspension rings 4 are provided on the upper part of the frame 3 at intervals, and the suspension rings 4 bind one end of a rope R shaped like a ladder that passes through a pulley 5 provided at the upper end of the hollow support 1. The other end of the rope R is fitted into a guide member 6 such as a guide rail installed vertically along the hollow support 1, and is tied to a lifting platform 7 that is lighter than the frame 3 that moves up and down.

The guide member 6 is provided with a latch 8 on its upper part that locks the lifting platform 7 when it is raised to prevent it from falling. The latch 8 can be released by an operating member 9 common to each floor.

Reference numeral 10 denotes an object that is placed on the platform so that it becomes heavier than the frame body 3 when the platform 7 is in the raised position.
When the latch 8 is released, the lifting platform 7 can be lowered by its own weight.

The present invention has the above-mentioned structure. First, the lifting platform 7 is normally in the raised position and is locked by the latch 8, and then the object 10 is placed on the lifting platform 7. When you want to evacuate due to a disaster, if you release the latch 8 using the operating member 9 that can be operated from each floor, the platform 7 will be unlocked and the frame 3 will be released.
The heavier lifting platform 7 starts to descend due to its own weight. At this time, the frame 3 to which the ladder-shaped rope R is connected is decelerated by the gear train reduction mechanism a meshing with the rack 2 and gradually descends. Lifting platform 7
When the rope ladder is lowered to the ground level, the rope ladder becomes tense and the evacuees evacuate one by one. When all the evacuees evacuate, the object 1 placed on the platform 7
When 0 is removed, the lifting platform 7 becomes lighter than the frame 3, and the frame 3 lowers due to the weight of the frame 3, and the lifting platform 7
is raised, and when the lifting platform 7 is located at the upper end, it is locked by the latch 8, and when this locking is performed, the object 10 serving as a weight is placed on it as before.

Therefore, the evacuee releases the latch 8 of the platform 7 that is locked at the top of the hollow column 1, and after the platform 7 is slowly lowered by the deceleration mechanism of the frame 3, the rope ladder becomes tense, and the rope ladder is used to descend and evacuate. Therefore, even the elderly and children can safely evacuate without any danger.Furthermore, when the evacuation is completed, if the object 10 on the elevator platform 7 is removed, the elevator platform 7 can be raised and locked, so there are no inconveniences. There is.

Claims (1)

[Scope of utility model registration request] A hollow column with a rack installed vertically on the inner wall is extended to each floor above the second floor and is installed vertically so that each floor can be connected, and inside the hollow column is a frame incorporating a speed reduction mechanism of a gear train that meshes with the rack. Furthermore, a guide member such as a guide rail along the support is provided on the outside of the hollow support, and a latch is provided on the top of this guide that can be operated and engaged in common on each floor. A lifting platform that is lighter than the frame body is provided so as to be able to be lifted and lowered by a member, and the lifting platform is provided with a rope formed in the shape of a ladder that hangs between the frame and a pulley provided at the upper end of the hollow support. An evacuation device characterized in that an object is placed on the elevating platform and becomes heavier than the frame when it is locked at the upper end.
