Description

[Detailed Description of the Invention] The present invention relates to a synthetic resin flying toy that can be played by being thrown by hand.

Hitherto, a flying toy as shown in FIG. 3 has been known, in which the entire circumference of a hollow bag 10, which is also filled with air, is fixed to the upper surface of a hollow ring 9, which is also filled with air. However, in this type, when flying, a spiral is formed in a part of the recess 11 having a V-shaped cross section formed by the inner upper side of the ring 9 and the lower peripheral surface of the hollow bag 10 fixed to the upper surface thereof. There was a moment when turbulence occurred and its stable flight was hampered.

The purpose of the present invention is to eliminate such defects in the above-mentioned type of flying toy. A short cylindrical body 2 made of a thermoplastic soft synthetic resin sheet is inserted between the upper and lower sheets 1 and 1', and the upper and lower edges of the cylindrical body 2 are connected to the upper sheet 1 and the lower edge of the cylindrical body 2. The lower sheet 1' is airtightly welded to a circumferential point inward from the outer periphery to form a sealed chamber 3 in which a small amount of air is sealed, and the upper and lower sheets 1, 1' are A ring-shaped sealed chamber 4 that can expand and contract freely is provided around the periphery by airtightly welding the entire outer periphery of the 2 to each other, and a supply/exhaust plug 5 is attached to the ring-shaped sealed chamber 4. A covering plate 6 made of a thermoplastic soft synthetic resin sheet having a diameter smaller than 1 is disposed, and the entire outer periphery of this covering plate 6 is airtightly welded to a location on the circumferential line of the upper sheet 1 that is inside the outer periphery of the upper sheet 1. A disk-shaped sealed chamber 7 that can expand and contract freely is formed, and a supply/exhaust plug 8 is attached to this disk-shaped sealed chamber 7.

Since the present invention has the above-mentioned configuration, the ring-shaped sealed chamber 4 and the disc-shaped sealed chamber 7 are expanded through both the supply and exhaust valves 5 and 8, and the lower sheet 1 is expanded by the so-called bulging caused by the expansion. It is played by making the center part of the ball concave and use it (see the drawing), then throwing it into the air and making it fly.The hemispherical shape of the top makes the flight relatively slow. Of course, it is slow and interesting, but especially in the present invention, the sheets 1 and 1' are formed on the lower surface by the inner side of the upper side of the ring-shaped sealed chamber 4 and the lower side of the periphery of the upper sheet 1. The lower side of the recessed part having a V-shaped cross section is coated with the recessed part, thereby reliably preventing the risk of outside air entering the part and causing swirl-like turbulence that would impede the stable flight of the flying toy. There is.

Claims (1)

[Scope of utility model registration request] Circular thermoplastic soft synthetic resin upper and lower sheets 1,
1' are polymerized, and a short cylindrical body 2 made of a thermoplastic soft synthetic resin sheet is inserted between the upper and lower sheets 1 and 1', and the upper and lower edges of the cylindrical body 2 are placed on the upper side. The sheet 1 and the lower sheet 1' are airtightly welded to points on the circumferential line inside the outer periphery of the sheet 1 and the lower sheet 1' to form an airtight chamber 3 in which a small amount of air is tightly trapped. . A covering plate 6 made of a thermoplastic soft synthetic resin sheet having a diameter smaller than that of the upper sheet 1 is disposed, and the entire outer periphery of the covering plate 6 is airtightly placed on a circumferential line inside the outer periphery of the upper sheet 1. This flying toy is made by welding to form a disc-shaped sealed chamber 7 that can expand and contract freely, and a supply/exhaust plug 8 is attached to this disc-shaped sealed chamber 7.
