Description

[Detailed description of the invention] The present invention relates to an improved structure of a triangular hang glider, in particular, which has a swept wing and a flexible wing. In order to realize the above-mentioned aircraft with improved structure, the sails forming the flexible wings are simply shaped using aggregate, which serves as a removable shaping material.

Generally, this type of aircraft is generally made of aluminum alloy and has a diameter of 40 plates to 50 ml and a wall thickness of 1 mm to 1.5 m, as shown generally and schematically in Figure 1.
The free ends of a central member 1 called a keel and left and right members 2 and 3 called spar located on the left and right sides of the central member 1 made of pipe material of m8 degree are fitted through the opening of the U-shaped plate 4,
For example, the central member 1 and the left and right members 2 and 3 are fixed at a fixed angle on the same plane by bolts and nuts (not shown).
A crossing member 5 called a crossbar, which intersects with each other, is perpendicular to the central member 1, and diagonally intersects with the left and right members 2 and 3, is connected and fixed at each crossing part with bolts and nuts. As shown in Fig. 2, a part of which is shown in cross section, it is sewn with a sheet of synthetic resin material and shaped into a triangular shape with a uniform bulge on the top surface at a slightly wider angle than 4 degrees or 50 degrees. A flexible sail 6 is formed, and a bag stitched part 7 is formed in the center and left and right parts of the sail 6, and the center member 1 and left and right members 2 and 3 are inserted in the longitudinal direction (in FIG. 2, the right member is inserted). 3 is inserted into the bag stitched portion 7.

), and furthermore, from the intersection of the central member 1 and the crossing member 5, a linear guide member 8 and a triangular steering member 9 that widen toward the end are installed in the vertical direction from the intersection of the central member 1 and the crossing member 5, respectively. A landing line is attached at a constant angle to the axis, and passes through the upper end side of the guide member 8 to the leading end side and rear end side of the central member 1, and the intersection between the left and right members 2 and 3 and the crossing member 5. The upper tension wire 10 called ``extends almost crosswise,
A perforated tongue 12 as shown in FIG. Similarly, lower tension lines 11 called flying tension lines extend from the left and right bases of the center member 1 to the leading and rear ends of the central member 1 and to the intersection of the left and right members 2 and 3 and the crossing member 5 in a substantially cross shape. A perforated tongue 15 is fixed to the free end of the upper tension wire 1.
0 and a part of the lower tension wire 11 is shown in the figure, the bolt 13
, and a nut 14 as a common member.

A support (not shown) for supporting and suspending the operator is attached below the top of the control member 9, and the center of gravity of the aircraft is displaced by shifting the position of the operator by moving the control member 90 back and forth and to the left and right. This figure shows a glider structure configured so that its course can be selectively controlled by raising the glider, lowering it, or turning to the right or left.

By the way, in the above-mentioned airframe structure, especially the wing structure, there is a known device in which the wing is preliminarily shaped and a shaping material is attached to the wing to improve its gliding performance to form a semi-fixed wing. .

However, in the above device, the attachment of the shaping material to the wing is a complicated structure, and this kind of simple structure is required, that is, the above hang glider structure requires ease of assembly, disassembly, transportation, and storage. There was a problem that it became unsuitable for the industry.

The present invention focuses on this point and constructs a simple /・ng glider by making it possible to easily attach and detach the shaping material to the wing.
In order to improve its glide performance, an embodiment of the present invention will be described below in detail with reference to the accompanying drawings FIGS. 4 and 5.

Sail 6A between center member 1A and left and right members 2A and 3A
A plurality of belt-shaped bag portions 16 are formed at symmetrical positions with respect to the central member 1 in substantially the traveling direction of the body, with the front end side closed and the rear end side open.

In this case, the bag portion 16 is formed by applying a strip of cloth from the back side of the sail 6A and sewing it together with the sail 6A.
In addition, an eyelet fitting 17 is fixedly fixed to the rear end of the bag portion 16 together with the sail 6A.

The metal fitting 17 is provided with an elastic member 1 such as a rubber cord.
8 is passed.

Further, a resin cylinder 19 is connected to the elastic member 18 in a camp shape with one end open and the other end closed. 2
0 is formed, and the elastic member 18 is inserted into this through hole 20.
is inserted and the free ends thereof are tied together to form a ring, thereby connecting the cylindrical body 19 to the bag portion 16.

Also, in the bag portion 16, there is aggregate 21 which will be used as a shaping material for the snow rule 6A.
is inserted, the distal end of the na 9 is stopped by the closed distal end of the bag 16, and the rear end protrudes from the open rear end of the pouch 16 by several degrees.

In this case, the cylindrical body 19 is attached to the rear end side of the aggregate 21 protruding from the bag portion 16 so as to press the aggregate 21 forward with the elasticity of the elastic member 1q, The elastic member 18 and the cylindrical body 19 form a pull-out means for preventing the aggregate 21 from being pulled out from the open rear end portion of the bag portion 16.

That is, in one embodiment of the present invention described above, the bag stitched portion 7 of the sail 6A is attached to the center member IA, the left and right members 2A, 3A.
(shown in the second figure), and connect the cross member 5, guide member 8, and steering member 9 together with the upper and lower tension wires 10 and 11 with bolts 13 and nuts 14 (shown in figures 1 and 3) to complete the fuselage. After assembly, the aggregate 21 is pushed in through the open rear end of the bag 16 of the sail 6A, and its tip is stopped at the closed end of the bag 16, so that it protrudes from the open rear end of the bag 16. The cylindrical body 19 is placed on the aggregate 21, and the sail 6A? The aggregate 21 can be stably supported and held within the bag portion 16 by being attached with the elasticity of the string-like elastic member 18 connected to the rear side.

Of course, when extracting the aggregate 21 from the bag portion 16, it can be easily disassembled by performing the reverse operation as described above.

As described above, according to the present invention, the sail 6A can be assembled by simply inserting and storing the aggregate 21 into the bag portion 16 formed in the sail 6A.
It has the advantage that it can be shaped into a certain shape, thereby improving the glide performance of the aircraft, and in this case, it can be easily installed and disassembled without sacrificing the simplicity of this type of aircraft structure. When transporting and storing the aggregate, for example, if the aggregate 21 is inserted into the cross member 5 or the like and stored, it is not bulky at all and is convenient, and has an excellent effect in practical use.
