Description

WORKING CLOTHES HAVING A PARACHUTE

The present invention relates to a work vest worn to prevent safety accidents caused by falling in high places when constructing a high-rise building, and more specifically, life-saving parachute is automatically unfolded when a safety accident occurs due to a fall. It relates to a work vest equipped with a life-saving parachute to reduce life-saving accidents.

The technical idea of the present invention is not only applicable to work vests worn by workers working at high places away from the floor, such as high-rise construction, bridges, electric poles, steel towers, underground constructions, etc., as well as other work clothes. It is possible.

In general, there is a high risk of a safety accident due to the worker's fall when working in a place far from the floor, such as high-rise construction, bridges, poles, steel tower construction. In this case, it often leads to human accidents. Therefore, a worker in a high place wears work clothes, puts a seat belt on it, and hangs a safety rope (life line) on the seat belt to perform the next work.

According to the prior art, the seat belt worn during work in a high place is used to fasten the hook of the safety rope to a predetermined part (for example, the waistband part or the backband part) while integrally connecting the waistband, the chestband, the shoulderband and the backband. It is manufactured in a structure with a ring installed and is to be worn separately on the work clothes.

However, the conventional seat belt configured to be worn separately as described above has a problem of being uncomfortable and uncomfortable during movement or movement because the belts surrounding each part of the body do not stick to the body after being worn.

In particular, the high place of the construction site is a complex installation of fixed structures and temporary facilities and relatively narrow work place and aisle, the above-mentioned conventional wearable seat belts are not close to the body, but lingering Or there is a problem that there is a fear of accident that the worker loses the center and falls due to the fastening, bumping or winding the seat belt to the surrounding facilities when moving.

In addition, when a worker falls, an impact of about 2 to 5 times the body weight is applied to the body through the seat belt, and most of the impact is concentrated on the lower back, which may cause a fatal injury such as a spinal dislocation. There is a problem that this is high.

The present invention has been made to solve the problems of the seat belt of the prior art as described above, the object of which is to provide a life-saving parachute that can reduce life-saving by having a life-saving parachute that is automatically unfolded in the event of a fall accident To provide a work vest.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of a work vest equipped with lifesaving parachute according to the present invention will be described in detail.

First, the parachute will be briefly described for understanding the present invention.

Although many parachutes are known today in many documents, only some types of parachutes are available.

The first form is a military parachute. In order to use this parachute, a soldier, usually a soldier, must be trained for the fall and carry a large bundle of supports including multiple belts, hard frames and seats. .

The second form is a gliding parachute. Gliding parachute usually has a wing shaped canopy and many types of glide control mechanisms that are additionally attached to the support of the parachute.

Both types of parachutes are inflated by high-speed winds that strike the parachute. For this reason, the two types of parachute are difficult to apply to the work vest.

In addition to the above two types of parachute, many kinds of new parachutes suitable for low air fall have been introduced. These low-fly parachutes use compressed air to inflate the canopy with full force. For these parachutes, the wear parts, the vest / suspension are still large and heavy and take time to fully wear them. These parachutes are usually stored in separate places before being used intentionally.

U.S. Patent Application No. 20050087653 discloses a parachute. The canopy is provided with an annular hose arrangement to allow it to unfold quickly and to be preferably stable. The device is fixed to a parachute and includes a rapidly-inflating inflation system, ie airbag systems. However, the expansion system of the annular hose and gas generator is very bulky as an emergency life saving system.

US patent application 20050020393 describes a parachute suitable for approximation at low altitudes and low air speeds. Trapezoidal inflation pockets sewn outside the bottom edge of intersecting triangular fabrics help the canopy to be estimated.

U. S. Patent No. 5,161, 755 discloses a canopy formed by stitching pieces of fabric, sheaths extending radially from the center of the canopy, and an expandable sheath connected to a compressed gas container past the conduit. A parachute including an envelope will be described. The inflatable envelope has a main body in its center and legs extending radially from the periphery of the main body, which legs and the main body are interconnected and expandable. The free ends of the legs are inserted into the corresponding sheaths and fixed to the canopy so that the main body of the inflatable sheath can be maintained at the center of the canopy. However, these legs can tear off the sheaths and canopy if a sudden vibration occurs, and the canopy can be folded while descending. This is a very dangerous situation.

U.S. Patent 5,028,018 describes a device (forward or gliding parachute) for accelerating the opening of the canopy, in particular having an air layer at the base along the periphery of the canopy. The air layer takes the form of, for example, a hose under high air pressure in the operating state or a fabric which does not allow air to pass through, so when the sheath is opened, the air layer expands in a very short time and only after 20 to 30 meters falls the flying device opens. do. When fully deployed along the perimeter of the canopy, the air layer forms a circular ring. However, if the parachute faces sudden vibrations, a reinforcing angle attached to one corner of the right and / or left handle side may tear off the canopy, and the canopy may collapse while descending.

The present invention may include some functions of the low-air parachutes presented above, and is an important feature of allowing the canopy to be unfolded quickly and automatically at the moment of the fall of the operator.
