Description

[Detailed Description of the Invention] This invention relates to a descending machine that can safely descend from a high point of a general two-story house, apartment, condominium, building, etc. by following a rope from a high place of the building. . Conventionally, when a fire breaks out in a general two-story house, child's apartment, condominium, building, etc., a person who is in a high place in such a building can easily and simply operate the descent to safely descend and evacuate. Since there was no fire available, there was no other option but to volunteer and wait for the arrival of the fire brigade, which was dispatched to the scene of the fire. In the end, the tragic rate of loss of precious lives was not small.

Therefore, in the case of a fire in any of the above-mentioned buildings, this invention can be used immediately and easily by men and women of all ages who are encountering a fire for the first time and have no experience in using descending aircraft. Descend safely and reliably to escape from the fire scene.
The descending aircraft of this invention not only enables evacuation, but also has a simple structure, is strong and lightweight, is easy to manufacture, is suitable for mass production, and is of course inexpensive. The purpose of this invention is to deploy this invention as much as possible in high places such as general two-story houses, apartments, condominiums, buildings, etc., and to use it to prevent fires from occurring in high places. The aim is to allow people to evacuate safely and prevent fatal accidents caused by conventional tragic fires that occur in high places in buildings.

The screw part 42 is screwed into the female screw hole 36 to form an adjustment pulley, and then the fixed end of a separate, sturdy, long running rope 43 is formed into a ring 44, and inside it is designed to prevent wear. Piece 45
The free end 46 of the running rope 43 is cut off and treated to prevent it from unraveling, and then the belt 47 is fitted with a belt fastener 49 with a pull-out stopper 48 that has a built-in spring, and a hanging ring 50 is fitted. and a frame 51 for attaching a suspension ring are fitted therethrough, and both ends of a short, sturdy connecting rope 52 are formed into loops 53 and 54, respectively, and abrasion prevention pieces 55 and 56 are provided inside each of them. They fit together and are separate pieces,
Attach a safety device 58 and a claw 59 to the appropriate positions of the hook 57, and drill a hole 60 for attaching a connecting rope at the base end of the hook 57. Next, attach a connecting rope 1 wheel difference 54 to the hanging ring 50 of the heald 47. In addition, the loops 53 of the connecting rope 52 are connected to the holes 60 of the hooks 57 in a chain form to form a safety belt, and then the free end of the connecting rope 43 is connected to the upper opening of the box body 1. Insert the shaft hole 3 for connecting the upper coupling fitting into the inside from the front, wind the upper roller 24 clockwise, then wind the movable roller 23 counterclockwise, and then rotate the lower roller 25 clockwise. A general two-story house consisting of a hook 57 that is fully pulled out from the front of the shaft hole 4 for connecting an unconnected metal fitting in the rear lower opening wound in the circumferential direction, and a hook 57 equipped with a safety device 58 is removably hung on the unconnected metal fitting 38; In the event of a fire in an elevator, an apartment building, a building, etc., the device relates to a descending machine that can safely descend from a high point of the building by following a rope. (See Figures 1 to 22, and Figures 24 and 25.) In the event of a fire, the victim can fix the fixed end of the rope 43 at a suitable location on a nearby building (Figure 23). (See) The free end 46 of the trailing rope 43 is hung down to the ground and a person on the ground holds it. By fully turning the control shaft 10 of the adjustment pulley to the left and moving the stepped portion at the rear end of the screw portion 8 of the control shaft 10 forward so as not to touch the front surface of the shaft moving connecting piece 18, the movable roller 23 is moved by the elasticity of the spring 21. It is placed in a state where it can freely slide and move forward against the pressure. Next, check that the box 1 does not move even if the part of the rope 43 below the box 1 is pulled with one hand and the box 1 is pulled down with the other hand. From there, wrap the safety belt around your chest and complete the equipment.At this point, as shown in Figure 26, hold the left handle 32 with your left hand and the running rope 43 above the box body 1 with your right hand. After suspending the body, the right hand is moved very gradually and released from the rope 43.Then, by turning the control shaft 10 to the right with the right hand and moving the moving roller 23 moderately backward, the upper roller 24 and the moving roller 23 , the lower roller 25 begins to rotate and the body begins to descend along with the box body 1. Turning the control shaft 10 to the right increases the descending speed, and turning it to the left slows it down, so finish operating the control shaft 10 with your right hand. If you change your right hand to the right handlebar 20 and prepare your body and wait, your body will be able to descend safely to the ground guard at an optimal and stable speed. However, if the evacuee is also involved in a fire, the first person who has finished using this invention's descent machine can be hoisted back up to a high place in the building and returned to the same position as before. All you have to do is evacuate the next person according to the procedure.Next, the principle of adjusting the descending speed is as follows.Even in the position where the spring 21 is compressed to the maximum, the front surface of the shaft moving contact piece 18 is □Turn the control shaft 10 counterclockwise so that the stepped portion at the rear end of the screw portion 8 is moved forward.

When the running rope 43 is pulled from above and below at the same time, the moving roller 2
3 slides forward and approaches the upper roller 24 and lower roller 25. In the present invention, the strength of the pulling force corresponds to the weight of the suspended person, and the force 1 is directly expressed as the degree of approach of the moving roller 23 to the upper roller 24 and the lower roller 25. If you observe this from another angle, the transmission rope 43 is connected to the upper roller 24 and the moving roller 23.
, the lower opening roller 25 is in the above-mentioned 30 = back-clasped state, and the strength of the grip is determined by the moving roller 23 relative to the upper roller 24 and lower roller 25.
It is measured by the degree of approach of
Furthermore, the strength of the frictional force is immediately reflected in a slowing of the descending speed.

As a supplementary explanation, if your weight is too heavy and the descending speed is too slow, turn the control shaft 10 to the right and press the front surface of the shaft movement connecting piece 18 with the step at the rear end of the screw part 8, and then move it in succession. If the roller 23 is moved back appropriately, the frictional force will be reduced and the descending speed will be increased. If the evacuee's weight is light and the descending speed is too fast, the person on the ground can pull the free end 46 of the rope 43 to change the state to the same as if the evacuee's weight had increased and slow down the descending speed. If the evacuee cannot adjust the control shaft 10 with his or her own knife, a person on the ground can slow down the descent speed by pulling the free end 46 of the rope 43 from below. The spring 21 has the function of preventing the axially movable connecting piece 18 from swinging and also making it easier to wrap the transmission rope 43 around the upper roller 24, the moving roller 23, and the lower roller 25. This invention has a simple structure, is strong and lightweight, is easy to manufacture, is suitable for mass production, and is inexpensive, among other advantages.
They can be installed in large numbers in high places such as the second floor rooms of ordinary houses, apartments, condominiums, and buildings. In addition, this invention is simple and easy to use and does not require training, so in the event of a fire, any person, regardless of age or gender, can immediately use this invention without waiting for rescue by the fire brigade, and quickly and safely use the invention described above. It is possible to evacuate by descending and escaping from a high place in each building. Additionally, this invention also has the advantage of being able to be used repeatedly and continuously in the event of a fire.
