FR2479136A1 - Release for parachute pack - is held closed by pins releasably connecting to rod which passes through pack apertures - Google Patents

Abstract

The parachute pack is made up of a flexible material (1) folded to form an enclosure in which the parachute is placed. The edges (3) of the material are held together at at least one point by an elongate rod, one end of which passes through holes (4) provided in the material and is connected to a locking pin. The other end of the rod passes through another hole in the back of the enclosure and is connected to a second locking pin. The parachute is released by removal of either one of the pins (6,8).

Description

Parachute bag
The invention relates to a parachute bag of the type comprising a flexible element, folded back on itself so as to constitute a plurality of flaps and to delimit an enclosure in which the parachute is placed, and having at least one closing point at which said enclosure is closed by maintaining the flaps by means of an oblong piece, a first end of which passes through said flaps and is provided with a locking member that now holds them in the closed position.

As a general rule, the locking member is constituted by a retractable pin or pin and can be actuated either by means of a manual system, or by means of an automatic system.

Most often it is located on the outer face of the bag, that is to say the one through which escape the constituent elements of the parachute. However, in certain cases, it can be located on the internal face which is in contact with the paratrooper.

Such devices can have certain drawbacks.

Indeed, the safety rules require, when the opening of the parachute bag is controlled by an automatic system, such as an automatic release for example, that this system is coupled with a manual opening system.

The juxtaposition at the same locking member of two opening systems increases the risk of malfunction due to the complexity of the mechanical couplings and the difficulty in making them.

 The present invention overcomes these drawbacks.

 It relates to a parachute bag comprising a flexible element folded back on itself so as to constitute a plurality of flaps and to delimit an enclosure in which the parachute is placed, and having at least one closing point at which the said enclosure is closed by maintaining the flaps by means of an oblong piece, a first end of which passes through said flaps and is provided with a locking member keeping them assembled in the closed position, characterized in that the second end of said oblong part passes through the flexible element and is provided outside of said enclosure with a second locking member, the unlocking of which also causes the opening of the bag.

 According to an embodiment in accordance with the invention, the oblong part is a halyard, or the like, and the locking members are retractable pins or pins.

Advantageously, the unlocking of one member is obtained by a manual system while the unlocking of the other is obtained by an automatic system.

 The present invention therefore provides the possibility of opening a parachute bag with different controls located on several sides of this bag, actuated simultaneously or not by means of identical or different systems.

 It is also possible, as is known elsewhere, to juxtapose two opening systems on the same locking member.

Other characteristics of the invention will emerge from the description which follows of an embodiment in accordance with the invention and from the appended drawing in which:
- Figure 1 shows a top view of a flexible element intended to form a parachute bag;
- Figure 2 shows the element of Figure 1 in the folded state;
- Figure 3 very schematically shows in section a parachute bag, according to the invention, containing a parachute;
- Figure 4 very schematically shows the bodies ensuring the closure of the bag;
- Figure 5 schematically shows a bag having several closing seals.

 In Figures 1 to 4, the reference 1 designates a canvas. This is cut appropriately in order to delimit after folding, as shown in FIG. 2, an enclosure 9 in which the parachute 2 is placed.

In a known manner, the flaps, such as 3, have orifices, such as 4 and, in the closed position, are kept assembled by threading on a halyard 5 and put in place at the end of this halyard with a retractable pin. 6, which can be actuated by a manual and / or automatic system, known per se and not shown
According to the invention, the second end of the halyard 5 crosses the part of the canvas forming the bottom of the enclosure, which has an orifice 7 for this purpose. This end is provided with a retractable pin 8, which can be actuated by a manual and / or automatic system, known per se and not shown.

The withdrawal of the pins 6 and / or 8 allows the release of the halyard 5 and causes the flaps 3 of the bag to open, from which it follows the escape of the constituent elements of the parachute 2.

The presence at the same opening point of a device allowing the implementation on either side of the bag of separate opening systems of course increases the reliability of opening the parachute bag according to the 'invention.

The embodiment shown has only one opening point located on the top of the bag, but of course the invention is applicable when the bag has several closing points, as shown in Figure 5, each of the points closure 10 can be equipped as described above.

 Of course, the invention is not limited to the embodiment described and shown, which has been given only by way of example.

 Thus, the flaps can be attached, in a manner known per se, to a canvas element constituting the bottom of the bag.

Claims (4)

1 / Parachute bag comprising a flexible element folded back on itself so as to constitute a plurality of flaps and to delimit an enclosure in which the parachute is placed, and having at least one closing point at which the closure of said enclosure is produced by holding the flaps by means of an oblong piece, a first end of which crosses said flaps and is provided with a locking member keeping them assembled in the closed position, characterized in that the second end of said oblong piece passes through the flexible element and is provided on the outside of said enclosure with a second locking member, the unlocking of which also causes the opening of the bag. 2 / bag according to claim 1, characterized in that said piece is a halyard and that the locking members are retractable pins or pins. 3 / Bag according to one of claims 1 and 2, characterized in that the unlocking of an organ is obtained by a manual system while the unlocking of the other is obtained by an automatic system.  4 / Parachute bag comprising an enclosure having a plurality of opening points, characterized in that at said points the closure is carried out according to one of claims 1 to 3.
