Description

[Detailed description of the device]

[0001]

[Technical field of invention]

 The present invention relates to a parachute, and more particularly to a parachute that can be reliably released and opened when a stall condition occurs in a paraglider or the like.

[0002]

[Prior art and problems]

 As a rescue parachute used in a conventional paraglider, a parachute body (not shown) is folded and stored as shown in FIG. Is becoming A connecting band 11 is attached to the inner sac 1, and the other end of the connecting sill 11 is fixed to the outside of the outer sac 2 by a user wearing a parachute. The suspended rope of the parachute stored in the inner capsule 1 is pulled out from the open end of the inner capsule 1 and arranged outside the inner capsule 1.

In such a rescue parachute, when an unexpected situation occurs, the stopper 3 is removed, the outer sac 2 is opened, and the inner sac 1 is thrown by hand. When the inner sac 1 is thrown in this way, the connecting band 11 attached to the inner sac 1 is fixed to the user, while the suspension cord is arranged outside the inner sac 1 so that the suspension cord is When the inner capsule 1 is fully extended, the inner capsule 1 is disengaged from the main body of the parachute and the umbrella is opened.

The rescue parachute as described above has a simple structure and is reliable, but in order to throw the inner capsule 1 to open the umbrella body, the hanging rope hangs down and the hanging rope is It is after the inner capsule 1 has come off completely. In this case, when the stopper 3 is removed and the inner sac 1 is pulled out until the umbrella is opened, the hanging rope extends fully for about 0.1 seconds and for throwing the inner sac 1 for about 1 second. It takes about 2 seconds and about 3 seconds to open the umbrella, which is 6 to 7 seconds in total. Even if the paraglider's rescue parachute has a slow descending speed of about 15 m / sec, it will descend about 100 m during this work.

In the case of an emergency as described above, there is no problem when the altitude is sufficiently high, but when the altitude is low, the ground may be reached before the umbrella is sufficiently opened.

[0006]

[Means for solving problems]

 The present invention has been made in view of the above problems, and an object of the present invention is to provide a parachute capable of opening an umbrella more quickly than in the past when an unexpected situation occurs.

In order to achieve the above object, the parachute of the present invention is a parachute having an umbrella body for gently lowering the suspended body by entrapping air, wherein the parachute is provided with an air bag at the top of the umbrella body. In addition, the air sac is expanded by the compressed gas, and the expansion of the air sac causes the guide umbrella to open.

According to the present invention, the guide umbrella is provided on the top of the umbrella body with the air bag, and the air bag is inflated by the compressed air so that the guide umbrella is forcibly opened. The opening of the umbrella brings about an advantage that the opening of the umbrella is smoothly performed. Therefore, the time to open the umbrella can be significantly shortened, and the umbrella can be opened with a descent distance of about half.

【Example】

 FIG. 1 is a plan view of an embodiment of the present invention. As is apparent from this figure, the parasit has an umbrella body 4, and a guiding umbrella 5 is provided at the top of the umbrella body 4. There is. The guide umbrella 5 is provided with an air bag 51 (indicated by a broken line in FIG. 1) inside thereof, and when the air bag 51 expands, the guide umbrella 5 is forcibly opened. .. In this embodiment, the air sac 51 is formed in a cross shape so as to communicate with each other, but the present invention is not limited to this and may be any structure as long as the guide umbrella 5 is forcibly opened. It may be one.

A gas cylinder, for example, a carbon dioxide gas cylinder 6 is provided at the center of the guide umbrella 5, and the carbon dioxide gas cylinder 6 is housed in a pocket 7 provided at the top of the guide umbrella 5 as shown in FIG. It has a special structure. Then, carbon dioxide gas is supplied into the air bag 51 to inflate it. In this way, the carbon dioxide gas cylinder 6 is provided at the top of the guiding umbrella 5 because the guiding umbrella 5 is opened and the carbon dioxide gas cylinder 6 is attached to the hanging rope 8 shown in FIG. 3 when the umbrella body 4 is opened. This is to prevent the umbrella from being entangled and to smoothly open the umbrella body 4. Further, the carbon dioxide gas cylinder 7 is housed in the pocket 7 at the top so that the carbon dioxide gas cylinder 7 is securely not entangled with the hanging rope 8. On the other hand, since the parachute body is preferentially released, the hanging rope is fixed to the outer capsule 2 so that the hanging rope does not hang down and get entangled with the body.

When such a rescue parachute is used, the parachute body is folded and stored in the outer capsule 1 as in the conventional case. In an emergency, when the lip cord 9 (see FIG. 4) is pulled to remove the stopper 3 of the outer bag 1 and the lip cord 9 is further pulled, the lip cord 9 rotates the operating arm 61 of the carbon dioxide gas cylinder 6.

The carbon dioxide gas cylinder 6 has a rotatable actuating arm 61 on the upper part, and the actuating arm 61 is swung as shown in FIG. 5 to release carbon dioxide gas and inflate the air bag 51. It is like this. The operating arm 61 has a locking groove 65 for locking the lip cord 9, while the lip cord 9 is formed with a locking loop 91. The locking loop 91 is locked in the locking groove 65. Further, a safety rope 64 is passed between the main body of the carbon dioxide gas cylinder 6 and the stop holes 62, 63 formed in the operating arm 61 to bind the loop 91 from the outside, so that the locking loop 91 extends from the locking groove 65. It doesn't come off.

When the lip cord 9 is pulled as described above, the safety cord 64 made of, for example, a thin wire is easily cut, and the operating arm 61 rotates as shown in FIG. By this movement, carbon dioxide gas is released from the cylinder 6 and injected into the air bag 5 to expand the air bag 5. For this reason, since the air bag 51 is formed inside the guide umbrella 5 in the shape of an umbrella, the guide umbrella 4 is forcibly opened. At this time, the loop 91 of the lip cord 9 is released from the locking groove 65 and becomes free. When the lip cord 9 does not come off the cylinder 6, the descendant must prevent the lip cord 9 from being released so that the opening of the guide umbrella 5 is hindered. However, in an emergency, people who descend are often in a panic and it is possible that they keep gripping the rip cord 9 as it is. Therefore, in this embodiment, only the loop 91 is locked in the locking groove 65, and after the lip cord 9 is pulled to operate the carbon dioxide gas cylinder 6, the lip cord 9 is removed. -ing

When the air bag 51 is inflated by carbon dioxide gas, the guide umbrella 5 opens as shown in FIG. The guide umbrella 5 rises with the wind. Therefore, the umbrella body 4 opens quickly (see FIG. 2). The reason why the guide umbrella 5 is forcibly opened in this manner is that it is difficult to open it with a normal guide umbrella when the descending speed is slow as 15 m / sec as described above.

In the parachute according to the present invention, it takes about 3 to 4 seconds from the start of pulling the lip cord to the opening of the umbrella body, and the descent distance can be shortened to half, about 50 m.

Although the parachute for a paraglider has been described in this embodiment, the present invention is not limited to this, and is applicable to the case of a slow descent speed that cannot be used by a normal separated and independent guidance umbrella. It can be any parachute used.

[0017]

[Effect of the device]

 According to the present invention, the guide umbrella is provided on the top of the umbrella body and the guide umbrella is forcibly opened, so that the umbrella body can be quickly opened even when the descending speed is slow. Has the advantage that Furthermore, there is an advantage that even an accident at a low altitude such as 100 m or less can be dealt with without any trouble.
