Description

[Detailed explanation of the invention] A. Purpose of the invention [Industrial application field] The present invention consists of a wing upper surface made of flexible cloth, a wing lower surface, and a rib made of flexible cloth that conforms to the shape of the wing. It consists of a canopy with an open leading edge of the wing so that the air pressure maintains the shape of the wing, a sling attached to the canopy, and left and right connecting bands between the sling and the attachment band. Relating to airfoil flight devices.

[Conventional technology]

The attitude of the airfoil flight device as described above is determined by the length of the suspension rope 5 fixed to the underside of the wing and the attachment strap 6 for personnel and cargo.
Since the length of the connecting band (including the string) 7 that connects with the main body is determined at the time of manufacture, it is impossible to adjust it arbitrarily.

[Problem that the invention attempts to solve]

Therefore, flight performance such as glide ratio, glide speed, and hang time is limited. For example, when flying in strong winds, the glide speed is limited and you cannot move forward, or when you want to obtain a large glide ratio, etc. It has been impossible to set or adjust flight performance by controlling the flight attitude according to flight conditions or flight objectives.

In addition, as a device that can control the flight attitude mentioned above, the length of the front side band with respect to the rear side band can be adjusted by pulling the middle of the band in the length direction to the front side band of the left and right connecting bands, making it slack, and fixing it in that state. Proposals configured to change the ratio (e.g. U.S. Pat. No. 3,866,862)
(see specification).

However, the means for pulling and loosening the front side band 18 (riser web) is to use a drawstring 26 (control strap) whose lower end is fixed to the band 18 along with the band 18, and a control strap that is attached above the drawstring 26. 18 and a buckle 30 through which the upper end of the drawstring 26 is passed.
Although the length of the band can be adjusted steplessly, the left and right bands 1
It is extremely difficult to get the lengths of 8 correctly aligned. Further, since the adjustment range of the length of the belt 18 is limited to the length of the drawstring 26, the control range of the flight attitude is small.

An object of the present invention is to enable the above-mentioned flight attitude to be controlled arbitrarily and over a wide range.

B. Structure of the invention [Means for solving the problem] The present invention arranges a wing upper surface 2 and a wing lower surface 3 made of flexible cloth, and a rib 4 made of flexible cloth that conforms to the shape of the wing. The leading edge of the wing is open so that the air pressure maintains the shape of the wing, and this canopy 1
In an airfoil flight device comprising a sling 5 fixed to a sling 5 and a left and right connecting band 7 between the sling and an attachment band 6, an adjustment loop 10 is attached to the left and right connecting band 7 along the length of the band 7. and attach the connector 8 of the left and right connecting band 7 and attachment band 6 to one of the 10 groups of adjustment loops, or connect any two loops selected from the 10 groups of adjustment loops with a connector or other means. This attitude control device is characterized in that the effective length or relative length of each of the front and rear connecting bands 7f and 7b of the left and right connecting bands 7 can be changed by connecting them with members.

[Effect]

By providing a means for adjusting the length of the left and right connecting bands 7 by installing loops 10 in parallel so that the user can adjust the length as desired, the effective length or relative length can be set arbitrarily, The flight attitude can be changed depending on the flight purpose.

〔Example〕

Generally, the connecting straps 7 are a pair of left and right, and each of the connecting straps 7 is connected to a V at front and rear 7f and 7b from the connector 8 with the mounting strap 6.
It is divided into And each connecting belt 7 before and after
A plurality of hanging ropes 5 are regularly attached to the connector 9 on the upper part of the cables f and 7b. Therefore, in order to control the attitude of the airfoil flight device, it is necessary to
It is possible to change the length of one or both of f and 7b, but rather than adjusting the length of the suspension rope, the left and right front and rear connecting bands 7
It is more economical (time and cost) to adjust the length of f and 7b.
In the present invention, the connecting band 7 is provided with a length adjustment device because it is low cost (cost) and reliable (requires fewer operating steps and fewer checks).

In the embodiment shown in FIGS. 2, 2a and 2b, front and rear bands 7f and 7 of a series of connecting bands 7 rising from the connector 8 in the front and rear are shown.
b, an adjustment loop 10 is provided in parallel. The loop is formed by partially sewing 14 cloth/tape along the main body band. By selecting one of the groups of loops 10 and positioning the connector 8 therein, the length ratio (relative length) of the front and rear bands 7f and 7b can be easily changed.

That is, as shown in Figure 2a, the relative length is adjusted to the front and rear connecting bands 7.
If the flight attitude of the airfoil flight device 1 when both are made equal is shown by the solid line 1 in Fig. 3, then Fig. 2 b
If the attachment loop of the connector 8 is changed from 10 ₁ to the front side band 7f of 10 ₂ so that the front side band 7f is shortened and the rear side band 7b is lengthened as shown in the figure, the connector 8
The effective length between the connector 9 on the front side band 7f side is smaller than the effective length between 8 and 9 on the rear side band 7b side, and the third
An uphill flight attitude is obtained as shown by the chain line 1' in the figure. In addition, it goes without saying that the same adjustment is made for both the left and right connecting bands 7 in FIG.

In the illustrated example, the connecting band 7 is a band-like body, but when it is constructed from a string-like body, the loop 10 is also formed from a string.

The length adjusting means in the embodiments of FIGS. 4a and 4b allows any two loops 10 ₁ -10 ₂ of the loops 10 to be connected to the connector or stay 12 or the string without changing the relative position of the connecting body 7 and the connector 8. The connectors 8 and 9 of the front and rear bodies 7f and 7b are joined together as shown in FIG. 4b, and the relative length between the connectors 8 and 9 is changed.

This example is suitable for a case in which the connector 8 to the attachment band 6 is of a fixed construction that cannot be removed. The loop 10 includes not only the front side band 7f shown but also the rear side band 7b.
Alternatively, it may be provided only on the rear side band 7b. Reference numeral 11 indicates a stopper ring located directly above the connector 8 of the front and rear bands 7f, 7b.

In the embodiment shown in FIGS. 5a and 5b, the connector 8 is positioned at the same length of the front and rear bands 7f and 7b as shown in the figure a, and the loops of the front and rear bands 7f and 7b are opposite to each other directly above the connector. Things 10 ₃ and 10 ₄ stay 12
Connect with (or connector/string). Also in the same figure b
The lengths of the front and rear bands _7f and _7b are made to be different as shown in FIG.

This configuration is effective when the connector 8 is movable with respect to the connecting band 7 and cannot be removed.

C. Effect of the invention As mentioned above, a means is provided that allows the user to arbitrarily adjust the effective length or relative length of each of the front and rear connecting bands of the left and right connecting bands between the hanging rope on the canopy side and the attachment belt for personnel and cargo. Therefore, the problems described in the above-mentioned problem section are solved, and flight performance can be improved by changing the flight attitude depending on the flight purpose. In addition, the adjustment means is provided with adjusting loops 10 arranged in parallel along the length direction of the left and right connecting bands 7, and one of the groups of adjusting loops 10 is provided with adjusting loops 10 between the left and right connecting bands 7 and the attachment band 6. Attach connector 8 or adjust loop 1
Since the configuration is such that arbitrary two loops selected from group 0 are connected by a connector or other connecting member, the effective length or relative length of each front and rear connecting band 7f, 7b of the left and right connecting band 7 can be adjusted reliably in stages. The lengths of the left and right connecting bands 7 are also aligned correctly.

In the embodiments shown in FIGS. 2a and 2b and 5a and 5b, the relative lengths of the front and rear connecting bands 7f and 7b are adjusted without changing the total length of the front and rear connecting bands 7f and 7b. Compared to the above-mentioned known attitude control device, the relative lengths of the front and rear bands 7f and 7b can be changed more than twice, and attitude control over a wide range is possible.

As described above, the attitude control device for an airfoil flight device according to the present invention has a simple structure and low cost, and its handling is extremely simple, easy, and quick.
