Description

[Detailed description of the invention] (Industrial application field) The invention enables a gliding parachute to turn in a stable state with little sinking, and to accelerate forward motion, while also being able to move forward in turbulence. The patent also relates to a pitching plate that dampens vibrations affecting the pilot.

(Prior art) Conventional gliding parachutes are constructed by dividing the sling ropes attached to the front and rear sides of the parachute wings into left and right parts and converging them, and directly connecting them to the upper sides of the left and right belts on both sides of the harness to complete the parachute. The pilot holds the break cord attached to the rear end of the wing and pulls it to deform the wing, causing the wing to turn in the direction of the pull due to the air resistance of the deformed part. Ta.

(Problem that the invention aims to solve) Therefore, when sudden vertical movements occur due to turbulence or other factors, the wings are shaken, and this movement is directly transmitted to the body of the pilot wearing the harness, which is particularly susceptible to other forces in the front, back, left, and right directions. It had the disadvantage that if it was shaken, it would be at the mercy of being shot.

Also, when the break cord is pulled, the rear end of the parachute's wings are pulled down and the parachute turns, but as the wings are pulled down and deformed greatly, the buoyancy of the entire parachute decreases, causing the parachute to sink and its altitude to decrease. Another problem was that if the wind speed became too strong during flight, the aircraft could not move forward and would sink, making it impossible to reach the destination.

The present invention allows the pilot to be stably supported by the parachute, to make turns with almost no sinking, to be able to accelerate forward, and to be easy to operate. The aim is to eliminate the above problems.

(Means for Solving the Problems) The present invention is a pitching plate for a gliding parachute provided to achieve the above object, and this pitching plate connects the sling 4 of the gliding parachute 1. This is an elongated plate 6 provided on each of the belts 5, 5 on both sides, which are converged and connected to each other on the left and right sides, and on the front side 6a of this plate 6, the suspension rope 4 on the front side of the parachute 1 connects the belt 5. The rear side 6b of this plate 6 is connected to the suspension rope 4' on the rear side of the parachute 1.
are connected via the belt 5, and
A mounting belt 7 to the harness 8 is connected to the lower part of the plate 6, and the mounting belt 7 is often connected to the lower part of the pitching plate 6 at least in front of the center. .

(Function) The pitching plate 6 configured as above
The wing 2 of the parachute 1 swings back and forth using the connecting part of the attachment belt 7 to the harness 8 as a fulcrum.
Even if the wing 2 is shaken back and forth, it is absorbed by the swinging of the pitching plate 6 alone and does not affect the pilot, and even if the wing 2 is rocked up and down separately on the left and right sides, the mounting belt 7
Since the signal is connected to the harness 8 by the wire, the signal is transmitted to the pilot in a buffered manner.

Also, when the pilot grasps either the left or right pitching plate 6, for example, and lowers the rear side 6b with a small movement of the wrist, the left rear suspension rope 4' of the wing 2 is pulled, and the left rear side suspension rope 4' of the wing 2 is pulled. is deformed and protrudes downward. Therefore, the parachute 1 turns to the left due to air resistance on the lower surface of approximately the left half of the wing 2.

In addition, by lowering the front side 6a of the pitching plate 6, the suspension rope 4 on the front side of the wing 2 is pulled, lowering the suppression angle of the air inlet of the wing 2, and reducing the air inflow into the wing 2. Accelerates as wind pressure decreases.

(Example) An example of the present invention will be described below with reference to the drawings.

Reference numeral 1 designates a parachute for gliding, which has substantially rectangular wings 2 that are long in the lateral direction.The wings 2 are constructed by connecting air sacs 3 that are long in the front and back direction in parallel, and the air sacs 3 in the center have an open front end. It has a portion 3', and the air flowing in from this opening 3' also flows into the air bladders 3 on both sides. Further, the partition wall 3a between each air bag 3 has hanging ropes 4, 4' attached to one end thereof.
are arranged in the front-back direction. That is, on the lower edge of the front end of the partition wall 3a of the air bladder 3 other than the air bladder 3 whose front end is open at the center, there is a fabric with an inverted triangular synthetic resin film attached to it with a glass fiber rod attached along the upper edge. A partition wall 3a is provided with a mounting piece 4a made of a relatively hard cloth or plate such as, a hanging rope 4 is attached to a hanging ring sewn to the lower end of the mounting piece 4a, and the hanging rope 4 is pulled down. This prevents the partial subsidence of the Furthermore, the hanging rope 4 attached to the rear thereof also has the above-mentioned attachment piece 4.
It is attached to the lower edge of the partition wall 3a by an attachment piece 4b made of hard cloth or plate similar to the inverted triangular attachment piece 4a, which is smaller than the attachment piece 4a. Hanging rope 4
is attached by being connected to a hanging ring provided at the lower end of the attachment piece 4b.

Also, on the rear side of the bulkhead 3a, a suspension rope 4' is attached to the lower edge of the bulkhead 3a by direct sewing or the like without using the above-mentioned attachment piece 4a, so that when the suspension rope 4' is pulled, the air bag The vicinity of the attachment portion of the hanging rope 4' is designed to easily bulge downward.

Furthermore, except for the suspension ropes 4, 4) of the central air bladder 3, the suspension ropes 4,
4', two adjacent ones are combined into one.

Reference numerals 5 and 5 denote belts on both left and right sides for suspending the pilot on the wing 2. At the upper end of the front side belt 5a, which is the front side of the pilot, there are two belts on the left and right sides from the center of the wing 2.
The slings 4 on the front side of the wing 2 that have been separated and bundled are connected to each other, and the sling 4' on the rear side of the wing 2 is similarly tied to the upper end of the rear side belt 5b that is on the rear side of the pilot. It is connected. 6 is a pitching plate attached to approximately the center of this belt 5,
This pitching plate 6 has an elongated shape, and its front side 6a and rear side 6b are fixed to the belt 5 by set screws 9.
It is attached to. Therefore, the belt 5 need not be a single belt, but may be divided into a front side belt 5a and a rear side belt 5b at the pitting plate 6 portion.

Further, a short mounting belt 7 is provided at a position biased toward the front side 6a of the pitching plate 6 via rods 6c supported on both sides of the pitching plate 6, and its free end is connected to a harness via a mounting ring 7a. It is connected to 8.

Reference numeral 10 denotes a break cord connected to a cable connected to the rear end of the bulkhead 3a of the air bladder 3. Conventionally, by pulling this break cord 10, the rear part of the wing 2 was moved in a flap-like manner to turn. An annular handle 10a is attached to the tip of the belt 5 through a ring 13 attached to the rear side belt 5b.

Reference numeral 11 denotes a stabilizer provided at both ends of the wing 2, which has a thin bag shape, has an opening 11a inside the upper part of the front end, and is divided by multiple rows of sewing in the front and back direction, and expands during flight to become slightly thicker. It is plate-shaped and is intended to improve straightness when gliding. The rope 12 attached to the front lower end of the stabilizer 11 is attached to the front belt 5a, and the rope 12' attached to the rear lower end is attached to the rear belt 5b.

FIG. 3 shows another embodiment of the pitching plate 6, in which a connecting portion 6d for the mounting belt 7 is integrally provided at the front end of the plate 6.

(Effects) The pitching plate in the gliding parachute according to the present invention is constructed as described above, and in particular, since the pilot is connected to the harness via the pitching plate that can swing back and forth, it is difficult to prevent turbulence from occurring. Therefore, even if the parachute is shaken by an impact, it will be cushioned and the pilot's body will be stabilized. Also, the pilot of this parachute should hold either the left or right pitching plate,
By lowering the rear side of the pitching plate with a simple, small movement of the wrist, the plate tilts around the connecting part of the mounting belt as a fulcrum, and the hanging plate connected to the rear side via the belt is When the rope is pulled, the left and right wing parts on the pulled side deform downward, and the air resistance of these deformed parts causes the parachute to turn to the pulled side. In comparison, the wing deforms less, making it possible to turn with less sinking, resulting in stable flight.

Also, when the front side of the pitching plate is lowered, the suspension rope on the front side of the wing is pulled, and the front part of the wing is tilted downward in the direction of flight, so the opening at the front end of the wing is also tilted. The flow of air from here is reduced, reducing wind pressure and increasing flight speed. Therefore, even in cases where a conventional flight would not be able to reach its destination due to a strong headwind, resulting in a drop in speed and sinking, it is possible to reach the destination with less sinking.

Furthermore, the pitching plate is easy to grasp and can be moved using the connecting portion of the attachment belt to the harness as a fulcrum, making it easy to operate.
