Abstract

<P>PROBLEM TO BE SOLVED: To provide a mounting structure of a slider of a small dimension capable of opening at a high opening speed. <P>SOLUTION: The mounting structure of the slider of a round parachute including a plurality of hole parts 42 provided on a slider main body 41 for inserting a plurality of suspension lines 2 mounted on an opening peripheral edge of a canopy 1 is characterized by that a part 2' of the suspension lines is not made to be inserted in the hole part. Thereby, a canopy part connected to the suspension line which is not inserted is protruded from a slider peripheral edge, and there is an advantage that the opening speed increases because air becomes easier to flow in from the canopy part. Therefore, even the slider of the small dimension can have the high opening speed. <P>COPYRIGHT: (C)2004,JPO

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slider mounting structure for a circular parachute, and more particularly to a slider for controlling the opening speed of a circular parachute.
The present invention relates to a slider mounting structure in which a small-sized slider body opens the umbrella immediately.

[0002]

2. Description of the Related Art A circular parachute has suspension lines 2 extending at equal intervals around the opening edge of a hemispherical canopy 1 as shown in FIG. 3, and the suspension line 2 is provided at the other end thereof. The falling object or the descendant 3 is connected.

In recent years, like the ram air parachute, the slider 4 has been used to delay the opening speed of such a circular parachute to reduce the impact at the time of opening the umbrella. This slider 4 is shown in FIG.
As shown in FIG. 3, a rectangular slider body 41 is provided with holes 42 at four corners, and a plurality of circular parachute suspension lines 2 are equally inserted into the holes 42. By attaching the slider 4 to the suspension line 2 in this way, with the opening of the umbrella,
The slider 4 slides downward to suppress the impact when the umbrella is opened. Reference numeral 43 is a reinforcing tape.

However, in the circular parachute, unlike the ram air parachute, the slider 4 is attached to the opening (air intake) of the canopy 1 (see FIGS. 5a and 5b), so that the slider body 41 is manufactured from a material having poor air permeability. In that case, there is a drawback that the opening is blocked and it is difficult to open the umbrella. Therefore, the slider body 41 is made of a material having good air permeability, for example, a mesh. This is for allowing air to flow through the openings through the gaps in the mesh. The air passes through the ventilation hole and flows into the canopy 1 to open the parachute.

Therefore, in order to increase the opening speed, it is necessary to increase the size of the slider 4 to be attached (see FIG. 5b), but since the air resistance of the mesh is considerably large, the desired opening speed is increased. Is difficult to obtain. Further, if the slider 4 has a large size, it may cause a problem during handling or packing.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a mounting structure of a slider having a small size and capable of being opened at a high opening speed.

[0007]

In order to solve the above problems, a slider mounting structure for a circular parachute according to the present invention has a plurality of suspension lines attached to the opening periphery of the canopy 1 and a plurality of holes formed in the slider body. In the slider mounting structure of the circular parachute inserted through the portion, a part of the suspension line is prevented from being inserted through the hole.

According to the present invention, since a part of the suspension line is not inserted into the hole of the slider, the canopy portion connected to the suspension line which is not inserted protrudes from the peripheral edge of the slider. Has an advantage that the opening speed becomes faster and the opening speed becomes faster. Therefore, there is an advantage that even a small-sized slider can obtain a quick opening speed.

[0009]

FIG. 1 is a side view of a slider mounting structure for a circular parachute. The circular parachute has a plurality of suspension lines 2 extending from a peripheral edge of an opening of a canopy 1 that opens in a hemispherical shape. The other end of 2 is connected to a falling object or a falling person 3.

As shown in FIG. 2, the slider 4 has a slider main body 41 made of a breathable cloth such as a rectangular mesh, and a reinforcing tape 43 for reinforcement is provided on the peripheral edge thereof. ing. Holes 42 for inserting the suspension lines 2 are provided at four corners of the slider body 41.

In the present invention, the hole 4 of the slider 4
A suspension line 2 extending from the peripheral edge of the opening of the circular parachute is evenly inserted in 2 and a part of the suspension line 2 ′ is directly connected to the falling object 3 without inserting the hole 42. There is. In this embodiment, the suspension line 2'adjacent to the suspension line 2 passing through the hole 42 does not pass through the two holes 42, but is directly connected to the falling object 3. The suspension lines 2'that do not pass through the holes 42 are adjacent to each other. In this embodiment, the suspension line 2 group that passes through the holes 42 provided at the four corners and the suspension line 2 ′ that does not pass through are configured as described above.

By adopting such a structure, the edge of the canopy 1 which does not pass through the hole 42 forms the opening 11 through which air can easily enter. Therefore, the air enters the canopy 1 more smoothly than the air passing through the air-permeable slider body 41, and the parachute opening speed can be increased.

[0013]

As described above, according to the present invention,
Since a part of the suspension line is not inserted into the slider hole, the canopy part connected to the suspension line that is not inserted protrudes from the peripheral edge of the slider. The advantage is that the opening speed is fast, and thus even a small-sized slider can obtain a quick opening speed.
