Abstract

The utility model discloses a lift flying disc relating to a plastic flying disc tool. The utility model discloses a plastic flying disc tool. A deformation can be made on the basis of an original plastic flying disc. The upper and the lower vertical edges of the flying disc can be changed into conical-shaped streamline edges, according to a radiation shape, the disc surface can be changed to a plurality of fan blades, and the fan blades are a little bit inclined. The flying disc is designed to be thrown by a right hand, and the flying disc can rotate in the clockwise direction while flying. Guiding edges (windward edges) of the fan blades are relatively higher, and following edges of the fan blades are relatively lower. Gaps are arranged between the guiding edges and the following edges, and airs can flow through the gaps. The cross sections of the fan blades are in the shape similar as airplane wings. Thereby the flying disc can generate upward lift under the action of the air force, and the flying effect of the flying disc can be improved.

Description

The lift flying disc

[technical field]

The present invention relates to a kind of plastic frisbee toy.

[background technology]

Present plastic frisbee toy is a flat U shape charging tray, sees Fig. 1.There are two all right improved places in this plastic frisbee:

1. flying disc lift when flight is not enough;

2. flying disc resistance when flight is big.

[summary of the invention]

The purpose of this invention is to provide a kind of when flight resistance little, and can produce plastic frisbee toy to climbing power.

For realizing above-mentioned purpose, lift flying disc of the present invention is on the basis of original plastic frisbee, to have made some modification:

1. change upright web up and down into the conical flow linetype edge, can reduce the resistance of flying disc when flight like this;

Card by radial several flabellums, the flabellum slight inclination made.Pressing the right hand and throw design, is to be rotated in a clockwise direction during flying disc flight.The guide margin of flabellum (windward side) is slightly high, and lagging edge is lower slightly, and leading has the space between the lagging edge, radial rectangular air-vent is promptly arranged on the card, and air can flow through from the centre, and the cross section of flabellum is made the shape near aircraft wing.Like this, flying disc will produce lift upwards under aerodynamic effect when flight, thereby improves the flight effect of flying disc.

Lift flying disc through above 2 modification is seen sketch map Fig. 2.

[description of drawings]

Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.Wherein:

Fig. 1 is present plastic frisbee toy sketch map.

Fig. 2 is the plastic frisbee toy sketch map after improving.

Fig. 3 is the plastic frisbee toy A-A generalized section after improving.

Fig. 4 is the plastic frisbee toy B-B generalized section after improving.

Wherein Reference numeral is represented respectively: the plastic frisbee toy that 1-is present, the plastic frisbee toy after 2-improves, 3-card air-vent, 4-flabellum guide margin, 5-flabellum lagging edge.

[specific embodiment]

Make the plastic frisbee toy by shown in Fig. 2 sketch map.During use, revolve with the right hand and to launch, flying disc rotates in a clockwise direction.Because card flabellum slight inclination, flying disc in flight course, just have air-flow and be threaded into the card below from card air-vent 3, under aerodynamic effect, will produce lift upwards, increased the hang time of flying disc.Have, the conical flow linetype edge is made at the edge of flying disc again, can reduce the resistance of flying disc when flying forward like this, and the flying distance of flying disc is increased.Increase the hang time, increased flying distance, thereby improved the flight effect of flying disc.

Claims

1. lift flying disc, it is characterized in that: web is the conical flow linetype edge, makes several flabellums to card by radial; The flabellum slight inclination is pressed the right hand and is thrown design, is to be rotated in a clockwise direction during flying disc flight; The guide margin of flabellum is slightly high, and lagging edge is lower slightly, leads the space of having asked of lagging edge; Air can flow through from the centre, and the cross section of flabellum is made the shape near aircraft wing.

2. lift flying disc according to claim 1 is characterized in that: the flying disc limit is the conical flow linetype edge.

3. lift flying disc according to claim 1 is characterized in that: radial rectangular air-vent is arranged on the card.
