Description

Emergency escape utensil of parachute

The present invention relates to a parachute emergency escape mechanism that is easy to carry and use. More specifically, the present invention is located in an upper floor of a high-rise building in an emergency situation such as a fire and utilizes an emergency stairway or other evacuation means such as a ladder or a helicopter. It is about lifesaving means that can be used even when it is not possible.

In general, emergency escape from high altitudes by life-saving devices such as parachutes is extremely dangerous and difficult, requiring not only a substantial drop height for the parachute to unfold and safely land on the ground.

A typical aircraft parachute has a diameter of 25 feet, a landing speed of about 5 m / sec and a minimum drop height of 50 m for safe landing.

The time required for free fall at relatively low altitude, such as high-rise buildings, is to fall freely at a height of 50M and land on the ground using H = 1/2 gt ² (H: height, g: gravity acceleration, t: time). It will take 3.3m / sec and 4.5m / sec at 100M, and the speed of landing on the ground will be 32m / sec at 50M height and 43m / sec at 100M by the formula s = gt (s: instantaneous speed). It will be enough.

Therefore, in order to be able to use the parachute emergency escape mechanism in a high-rise building, a parachute with a sufficient area for easy use and rapid deployment of the parachute and deceleration of gravity acceleration with respect to weight is required.

As a parachute-type life-saving device for emergency escape from low air, that is, escape from a high-rise building in case of fire, equipped with a parachute on a frame such as an automatic unfolding umbrella as shown in Utility Model Registration Room 1986-204. Let the parachute unfold,

As shown in Utility Model Registration Room 1986-2092, the double-circle tube was fixed to the parachute body and the parachute was rapidly deployed with compressed gas.

Multi-stage parachute with parachute in multi-stage umbrella frame as in patent registration 10-232706,

As disclosed in Korean Patent Laid-Open No. 2002-23927, a parachute cloth is provided on an umbrella-type frame so that it can be quickly unfolded by the frame when falling.

The known emergency escape lifesaving device solves the problem of allowing the parachute to be unfolded quickly by using a device such as an umbrella meat or the expansion force of compressed air. Due to the resistance of the parachute having an area that can be reduced to a sufficient level can not be obtained, there was a problem that the landing speed can not be reduced to a safe level.

The present invention is to solve the above problems, but to quickly deploy the parachute using the spring and the frame, such as an automatic spread umbrella, in a state folded inward at the end of the frame so that the deployed parachute has a sufficient diameter It extends and stores the parachute, and connects a plurality of parachute ropes to the end of the parachute to double the expanded diameter of the parachute, and to have a parachute on the upper part of the expanded parachute to reduce the landing speed to the maximum when falling. It is done.

Still another object of the present invention is to simplify the construction of the lifesaving equipment and to improve the convenience of storage and handling by using a parachute storage bag as a means of binding the parachute and the body during the fall.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

1 is a perspective view showing a state of use of the present invention, Figure 2 is a block diagram of the present invention parachute.

The subject innovation consists of a harness portion (10) for binding the body to the secondary parachute (1) and the main parachute (2) and parachute.

The main parachute 2 is composed of an automatic unfolding mechanism 11 which is automatically unfolded by pressing the spring 4 fixing device 5 like a known automatic unfolding umbrella. The secondary parachute (1) is attached to the velcro (6) in the unfolded state, and the air chute (7) of a suitable size is provided at the center of the main parachute (2) so that the secondary parachute can be developed by the internal air when the main parachute falls. ) Is formed.

Inside the main parachute, that is, the frame 8 is provided with the main parachute extended inwardly by the radius of the frame along the outer periphery of the main parachute, and the inner periphery of the main parachute stored there are a plurality of connecting lines 9. The end of the connection line (9) provided with a dog is connected to the parachute harness (10).

3 is a block diagram of the present invention parachute storage bag.

One side of the storage bag 20 is provided with a binding portion 12 which is connected to the main parachute connecting line 9, and the handle 13 used for carrying when the main parachute is stored, the suspenders on both shoulders when using the parachute One side of the bag body 14, which is formed to serve as a long side is provided with a connecting rod 15 is coupled with the binding band 16 for binding the chest at the front waist of the body passing between the back and both legs of the body, Hanging ring 17 is formed at the end of the connecting rod is caught on the parachute binding unit 12.

It describes the operation according to the configuration of the present invention as described above.

When using the designed parachute emergency escape mechanism, open the bag 18 of the bag containing the parachute, take out the parachute and connecting rod 15, and then carry the bag's handle 13 on the shoulder of the bag. (14) and the connecting rod (15) is located in the front part of the body from the back to the legs between the two, and bind the chest portion with the binding band (16) formed on the chest and the hook ring (17) formed at the end of the connecting rod is the main Hang on the parachute tie.

When the body binding is completed, holding the main parachute handle 13 connected to the main parachute binding unit, the main parachute is vertically pressed, and the main parachute is deployed by pressing the button of the fixing device 5.

When the main parachute (2) is deployed and jumped out, the support 19 built in the multi-stage sliding type exits the inside of the handle 13, and the main parachute 2 folded inside the umbrella form is opened and the main parachute unfolds. The secondary parachute (1) attached to the upper surface of the main parachute is also unfolded to be able to land safely.

As described above, the present invention provides a parachute of a sufficient size to shorten the unfolding time when falling in a relatively low air space, such as a high-rise building, to alleviate the restriction of the drop height and to reduce the acceleration of gravity by resistance to air. In the event of a disaster such as a fire in a high-rise building, it can be used as a means of lifesaving.
