Abstract

The utility model relates to a self-return flying wing based on the action of an upper recoil angle of wings, which is a novel throwing flying toy. The utility model can return above a pitcher's head about a plurality of meters after being thrown out and then rotate down to land slowly. The utility model can be played in a small vacant land and indoor space. Throwing skills can be grasped without training. The utility model has the advantages of slow flying speed, high safety, simple structure, material saving and wide material source. The utility model is suitable for low-skilled labor intensive batch production.

Description

Self-return flying wing based on the action of upper recoil angle of wings

The utility model is a kind of throwing flying toy boomerang (BOOMERANG).

Traditional boomerang is former to be as a kind of weapon, is used to go hunting by Australian original inhabitants.The people was arranged afterwards also used as athletic equipment, threw match.Traditional boomerang weight is big, and the flying speed height uses dangerous big; Need the long period training to grasp and throw skill; It is big to throw required place, so can not popularize as toy.In addition, the wing curve required precision of traditional boomerang is also higher, is unfavorable for producing by batch.

The utility model has utilized the pneumatic principle different with traditional boomerang, and purpose provides the boomerang that a kind of serviceability satisfies the toy requirement.

Another purpose of the present utility model provides a kind of new simple structure, reaches easy to use effective, is beneficial to the mass-producted purpose of low technical.

Structure of the present utility model is that the fin of lightweight has the upper counterangle, as accompanying drawing 1.Position anti-on the fin can be on any length of spanwise.Aloft deflecting force is produced by the effect at the upper counterangle, and therefore wing can be plate shaped, fully need not the necessary plano-convex of traditional boomerang or concavo-convex wing.

Compare with traditional boomerang, performance of the present utility model has accomplished that flying speed is low, and is safe in utilization; The revolution distance is short, can be in little vacant lot and indoor object for appreciation, and air force is stable, no matter throws weight.How are angle of launching and rotating speed, the thrower crown of all flying back; Fly back neither resemble when coming and hit back facing to the thrower traditional boomerang, must be very careful in order to avoid beaten, but thrower's overhead number that flies back is meter high, slowly rotation decline can be caught by easy stages.

The utility model is simple in structure, need not be crooked wing, reduced the specification requirement of making, productivity ratio and finished product rate all can improve.Also have materials to economize in addition, therefore the advantage that material source is wide can accomplish to produce detective, and fixed investment is little, suitable labor-intensive production.

Accompanying drawing 2, accompanying drawing 3 are two examples in addition of the present utility model.

Claims

1, a kind of boomerang, it comprises fin and the connector that is connected fin, it is characterized in that fin has the upper counterangle, wing is plate shaped.

2, boomerang according to claim 1 is characterized in that going up of the upper counterangle is anti-partly to make annex and be contained on the wing.
