Description

[Detailed description of the invention] (Field of industrial application) This invention allows you to float in the air by moving at a high speed, such as running down a slope, and glide stably even when changing direction. This invention relates to a parachute for gliding.

(Prior art) Recently, parachutes have been used to levitate above the ground and enjoy flying through the air. Conventionally, parachutes have been made by using the so-called umbrella part of the body of the parachute, which consists of long and thin air sacs that are open at the tip in the direction of travel, and are arranged in parallel. When the parachute was attached and the parachute moved forward, air flowed in through the opening at the tip of each air sac, causing each air sac to expand, allowing a person suspended from the parachute to glide. However, when the sling on one side of the rectangular parachute was pulled in order to correct the glide direction, the parachute on that side became deflated and changed, making it susceptible to stalling.

Therefore, air sacs of similar shape that were both closed after the tip were arranged on both sides of the air sac, and a partition wall was used between each air sac, and air circulation holes were opened in these partitions.As the parachute moved forward, it opened. The air flowing into each air sac inflates each air sac into a cylindrical shape, and also enters the occluded air sac through the air flow opening in the septum, putting the entire body under tension, and pulling down the occluded air sac on either side. They were designed to prevent the air sacs on both sides from collapsing when the direction was corrected.

(Problem to be solved by the invention) Since the above parachute has air sacs closed at the front and rear ends on both sides, even when the lateral air sacs are pulled by the sling when correcting the direction of glide, The air sacs in this area are not easily deflated, but due to the air circulation opening in the septum between the air sacs, which have an opening at the tip, the air in the closed air sacs at the front and rear ends opens the tip. Because the air sacs on the sides tend to collapse, it is difficult to maintain sufficient buoyancy when changing direction.

The purpose of the parachute for gliding according to the present invention is to enable stable gliding with little deflation of the air sacs on both sides and no decrease in buoyancy even when the direction of glide is corrected.

(Means for Solving the Problems) The present invention is a gliding parachute proposed to solve the above problems, and is made of a sheet-like material and has an elongated end with an opening 2a in the direction of travel. Air sacs 2 are successively formed in close parallel,
At least one similar air sac 2' whose front and rear ends are closed is continuously formed on both sides of the air sac main body 1.
A partition wall 3 is formed between each of the air bags 2 and 2', and an air circulation port 4 is opened in the partition wall 3.The air bag body 1 has a partition wall 3 on its lower surface including at least both side edges. A parachute for gliding in which a plurality of hanging ropes 5 are connected to the front and rear ends of the main body 1, and the other ends of these hanging ropes are connected to a mounting belt 6, the tip of which is connected to an opening. air sac 3
The communication port 4 of the partition wall 3 at the connecting portion with the air bladder 2' whose front and rear ends are closed is a larger opening than the communication ports 4 of the other partition walls 3, and the communication port is provided with a mesh. A fabric 7 is stretched over the entire surface of the communication port 4, and the closed air sac 2' in the partition wall 3 is
On the side surface, there is an airtight fabric 8 having a size that covers at least the entire surface of the flow port 4, and at least its upper edge 8a is fixed to the upper edge 4a of the flow port. be.

(Function) In the gliding parachute configured as described above, air is released from the opening 2a in the traveling direction of the air bag 2 when the glider wears the attachment belt 6 on his body and runs down a slope. The air sacs 2 that flow along each bulkhead 3 and make up most of the central part are inflated into a cylindrical shape and tensed to withstand the wind pressure when moving forward without bending, and are suspended from a parachute. The turgor creates tension in the lower back so that it can support the weight of the person being held. In addition, air sacs 2', which are continuously formed on both sides and whose front and rear ends are closed, pass through the mesh fabric 7 stretched over the entire surface of the air circulation opening 4 that opens in the partition wall 3, and are closed. The airtight fabric 8 on the side of the air bag 2' is pushed aside, air flows in from the air bag 2, the air bag 2' is tensed, and the main body 1 together with the air bag 2 is brought into a swollen and tensioned state.

The airtight fabric 8 fixed to the upper edge 4a of the air flow opening 4 is pushed away by the air inflow pressure when air flows in from the air bag 2 side, but once the inflow is completed, the air inflow pressure disappears, so that the air It hangs down to cover the inlet 4, and the air inside the air sac 2' flows into the air sac 2.
Even if the air tries to flow back into the air, the air pressure P causes the airtight fabric 8 to stick to the mesh fabric 7 stretched over the entire surface of the air vent 4, covering the air vent 4. Air is prevented from escaping.
Therefore, air sacs 2' on both sides are used to correct the glide direction.
Even when the air bag 2' is pulled downward, the air bag 2' does not lose its tension and is not distorted, so buoyancy is not lost and there is no stalling.

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

1 is the main body of the gliding parachute, which has sheets that are airtight, water resistant, heat resistant, waterproof, and has high tear strength placed on the top and bottom, and is formed into a long and narrow cylinder by the partition wall 3. The air sacs 2 are formed in parallel, and each air sac 2 is also provided with a partition wall 3 and a parallel partition 3' in the center, and the three air sacs 2 in the center are arranged in the direction of travel. The tip thereof is the opening 2a. In addition, the three air sacs 2' formed on both sides are closed at both the front and rear ends, and the partition walls 3 between each air sac 2, 2, 2, 2', and 2', 2' are closed.
There is an air circulation opening 4 in the partition wall 3 in each air bladder 2, 2'.
are opened and adjacent air sac sides communicate with each other.

Furthermore, a mesh fabric 7 is provided over the entire surface of the air circulation opening 4 of the partition wall 3, which serves as a continuous connection between the air sac 2 having the opening 2a at the tip and the air sac 2' having the front and rear ends closed.
is stretched by sewing 9 or the like. The mesh fabric 7 used had a mesh size of approximately 1 mm square, but is not particularly limited to this.

Note that the air flow opening 4 of the partition wall 3 is made larger than the air flow openings 4 of the other partition walls 3, so that a large amount of air can flow in in a short period of time.

Further, on the surface of the partition wall 3 on the side of the closed air bag 2', an airtight fabric 8 such as nylon coating, which is sized to cover the entire surface of the air circulation opening 4, is attached so that its upper edge 8a is connected to the air circulation opening 4. It is fixed to the upper edge 4a by sewing 9 or the like and hangs down so as to cover the flow opening 4. A plurality of slings 5 are connected at predetermined intervals to the lower surface of the air bag body 1 across the bulkhead 3 portion and the front and rear ends of both side edges 1a and 1a, and the tips of the slings 5 are used for attachment. It is connected to the belt 6,
The glider's body is tied down by the attachment belt 6, and by pulling one of the slings 5 connected to both side edges 1a, the air bladder 2' on that side is pulled down. As a result, the balance of buoyancy and the way wind pressure is received change, and the direction of glide changes.

(Effects) Since the parachute for gliding according to the present invention is constructed as described above, the air sac with an open end expands into a cylindrical shape by the air flowing in from the opening, and air flows out from the opening during gliding. The air sacs are press-fitted and air flows into the adjacent air sacs from the air flow holes provided in the adjacent bulkheads, and each air sac is made to have an average tension and is strong enough to suspend the weight of a human being. In addition, air flows into the air sac, which is closed at both front and rear ends, by pushing up the airtight fabric from the air sac, which has an opening at the tip, through the mesh fabric of the air flow opening in the partition wall, and the air inside the air sac is The airtight fabric is pressed against the mesh fabric by its air pressure, blocking the air flow opening and preventing air from flowing out, so even if it is squeezed by a sling to correct the glide direction, it will not be taut. It does not collapse, shrink, or deform, and does not lose its buoyancy, allowing safe and reliable gliding.
