Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an escape device for M-erosion from a high place in the event of a fire or the like.

Conventionally, rope ladders, ropes, etc. have been used as emergency escape devices from high-rise houses and high-rise buildings, but they are not suitable for people with fear of heights, women and girls, and are dangerous because they sway due to the wind.

Unlike a simple evacuation ladder or rope, the present invention securely clamps a transmission roller chain between a plurality of sprockets.
This is an extremely safe and easy-to-operate evacuation escape device in which the evacuation device is transmitted through this chain and can be freely lowered and raised by manual operation by the evacuee.

Next, the present invention will be explained and explained based on the drawings.

FIG. 1 is a longitudinal sectional front view of an apparatus according to an embodiment of the present invention, FIG. 2 is a longitudinal sectional side view thereof, and FIG. 3 is an explanatory diagram showing an internal structure.

In the figure, 1 is the main body of the evacuation escape device, and 6 is the main body of the evacuation escape device, with two main and sub boxes 2 and 3 supported on one side by a shaft 4. It is locked and fixed together with a clasp 5.

Inside one of the main and sub-boxes 2 and 3, the axle box 3,
The upper and lower chain holding sprockets are used as a holding means for suspending the main body 1) 6, 6 force (4+11+) is supported, and cuts 7, 7 are provided in the upper and lower plates of this sub-cylindrical body 3, and furthermore, the main box body 2 A guide path for the transmission loaf chain 8 is formed by cutting out a lower part of the chain.

A brake drum 9.9 is integrally connected to each of the presser sprockets 6.6 as a brake jI&IM for suppressing the falling speed, and furthermore, brake shoes 10, 10 are pressed into contact with the brake drums 9, 9. There is. The arms ioa, ioa of the brake shoes 10, 10 are combined and pivotally supported at a fulcrum shaft 11.

Further, one end of the lever beam 13 is connected to the fulcrum shaft 11, and the other end projects to the outside through a hole 12 bored in the sub-box body 3. At the tip of this lever beam 13, there is a fourth suspension ring 14 to which the fiB for evacuee A is attached, as shown in the figure.
is pivoted.

Next, the presser sprocket 6 is attached to the other main box body 2.
．． A sprocket wheel 15 to be engaged with the chain 8 is provided at a corresponding position in the middle of 6, with its horizontal shaft 16 being pivotally supported within the gold main box body 2, and a transmission sprocket wheel 17 is mounted on this horizontal shaft 16. It is fixed.

An intermediate sprocket wheel IL/18 corresponding to the transmission sprocket wheel I/17 is fixed to a transmission shaft 19 horizontally installed in the lower part of the main box body 2, and is interlocked with the transmission sprocket wheel 17 by a transmission chain 20. It is provided.

Further, two large and small freewheels /L/21 and 22 are fixed to the transmission shaft 19 at regular intervals, and the large freewheel /X/21 is provided to raise the main body 1 and rotates clockwise. The structure is such that driving force is transmitted only in the case of rotation in the opposite direction, and idling occurs in the case of rotation in the opposite direction. Also, the small freewheel/l/22 is the large freewheel/L'21.
It has the opposite configuration.

On the other hand, a rotation shaft 23 having a hand /v24 projecting to the outside of the main box body 2 is disposed diagonally below the transmission shaft 19, and the rotation of this shaft 23 is caused by the rotation of the above-mentioned large and small freewheel /l'21.22.
Two driving wheel sprockets 25 are attached to the rotating shaft 23 corresponding to the
, 26 are fixed. These large and small freewheelers
Iv21.22 and two small drive sprockets 25, 2
6 and drive chains 27 and 28 are respectively passed through.

In addition, in order to prevent the sprocket wheel μm5 from rotating due to the weight of evacuee A, a rotation prevention mechanism (not shown) is installed on the hand 1v24 side using a pin or the like.
Only when operating the hand/L'24, remove the pin etc. and rotate it.

Next, 8 is a chain that is engaged within the main body 1 as described above, and this chain 8 is usually a thick chain for several people, and a chain for large bicycles. As shown in Fig. 4, this chain 8 has one end wound around a winding drum C installed on the roof of a building, etc., and is attached to a #14D hanging from a window when needed. Pull the pulled handle dt-tightly, loosen the brake lever E provided on the winding citrus C, and let the other end of the chicone 8 hang down using #F.

The present invention has the above-mentioned structure, and in order to use it, the clasp 5 that fastens the main and sub-boxes 2 and 3 is released, both boxes 2 and 3 are opened, and the chain 8 After aligning between the notches 7.7, that is, between the presser sprockets 6.6, the main and sub-box bodies 2.3 are closed and fixed with the clasps 5, as shown in FIG. are consistent. At this time, since the Nupro rocket wheel 1v15 cannot be rotated, the main body 1 remains stuck on the chain 8.

Thus, evacuee A is supported by this subject 1,
Hand mounted on basket B and prevented from rotating with a pin etc. /I/
24t - Handle 2 released and attached to main body 1 with one hand
9 and turn the node A/24t with the other hand, you can descend safely by following the chain 8.

Also, if you are unable to descend due to flames or the like during the descent, by turning the hand/V 24 in the opposite direction, the large freewheel A/21 for ascending will rotate, allowing you to ascend with a small amount of force.

As explained above, according to the present invention, the escape device itself is held by engaging and clamping the roller chain hanging from the roof of a building etc. from both sides with sprockets, and the escape device itself is held by the roller chain hanging down from the roof of a building. By transferring the weight of the brake shoe to the brake drum, the brake shoe is brought into pressure contact with the brake drum, and the escape device can be lowered and raised by rotating the handlebar, which has the following excellent effects.

■Due to its structure, the evacuation type transmission roller chain is securely connected to the sprocket wheel, and there is no risk of slipping.

Also, there is no danger of the burnt being damaged by flames, etc.

■The evacuation escape device is formed of a box body, and the chain can be easily secured inside the box body by sandwiching a chain in the middle and closing it, so it is easy to handle and should be installed in each room on each floor. There is no need to ask for help from others when evacuating.

■The brake drum and brake shoe, which are braking devices, prevent sudden descent, so you don't have to worry about descending, and even if you get dizzy or faint, you won't fall too quickly.

■By fixing two small sprockets to the handle side and providing two corresponding freewheels,
It can go both down and up, and because the gear ratio between the small sprocket on the handle and the freewheel is large, when going up, a large amount of force can be transmitted with a small amount of force, making it extremely easy to operate.

As described above, the present invention is extremely simple in structure, yet reliable and safe, and is ideal for evacuation in the event of a fire, and can also be used as a construction tool in high places.
