CN2327429Y - Sailplane for coming back to start point - Google Patents

Abstract

The utility model relates to a sailplane for flying back to the start point, particularly a sailplane which can fly back to the start point along a circumferential direction after being projected. A light material is cut to form a sailplane body, a main wing and a tail wing. The front section of the sailplane body is cut and provided with a first embedding loss seam which can be embedded and provided with the main wing. The back section of the sailplane body is provided with a second embedding loss seam which can be embedded and provided with the tail wing. Particularly, the first embedding loss seam of the sailplane body is provided with an elevation and the second embedding loss seam is provided with a depression angle. The binding site of the main wing and the sailplane body is somewhat deviated to one side, which enables the sailplane for flying back to the start point to present the state that the wing sheet on one side is somewhat bigger than the wing sheet on the other side. Thus the flight barycenter can be changed and the utility model can fly back to the start point along the circumferential direction.

Description

The aerodone of original place can fly back

The utility model relates to a kind of fun toy, refers to a kind of aerodone especially.

As shown in Figure 1, be general fun aerodone structure, it is with light material such as cardboard, natural pearls plate etc. cuts to form a glide body 1, and be provided with the opening hook backwards breach 11 of pulling in the nearly prow of ventral place, be to pull in this belly hook breach 11 of pulling during use with powerful rubber band hook, and towards projecting direction tensile strength rubber band with the storage potential energy, and open kinetic energy to produce powerful bullet after loosening powerful rubber band in moment, penetrating (or with hand-held this body 1 towards projecting direction by glide body 1, directly project), then should promptly advance by glide body 1, and glide in freedom of the air, till air-flow disappears along with the air-flow in the atmosphere from this direction, because from whole projection process, can allow the child fully satisfy it and play interest, and can be by wherein understanding strength and the phenomenon of learning the Nature and various physical principles, therefore, playing aerodone almost is the memory that everyone as a child all had, and spreads so far always, does not eliminate along with the differentiation in epoch.Only, it is promptly can't control its heading by the people in projecting back glide body 1 for this kind aerodone structure, and fully along with its trend of the airflow direction left and right sides, therefore, the body 1 that often glides flies on high building roof, the tree, other people garden, big gutter ... can't regain Deng locating, usually make that the service life of a new glide body 1 is not long, the child that normal order is held thereby cry and scream endlessly causes father and mother's puzzlement.

In view of this, creator spy of the present utility model is to be engaged in the rich experiences of being accumulated that manufacture and design of Related product, deep study and analysis, through permanent effort, finally develop the utility model " aerodone of the original place of can flying back ", and in checking back discovery on probation on the spot, it really can effectively reach set practical effect, can be rated as the excellent novel creation of a dark tool intention.

Be that main purpose of the present utility model provides and a kind ofly can follow the fly back aerodone structure of original place of circumferencial direction after projection.

The purpose of this utility model is achieved in that

A kind of aerodone of the original place of flying back, be to constitute aerodone fuselage, main wing and empennage with the light material cutting, but in this nosing is to be cut with first of setting-in main wing to embed scarce seam, but back segment then has second of setting-in empennage to embed lacks seam, this main wing and empennage are corresponding respectively the embedding in the scarce seam of first and second embedding, are to cooperate to be embedded with a screw body in fuselage prow place; It is characterized in that: it is to have about 2 ° elevation angle that this fuselage first embeds scarce seam, second embeds scarce seam then has about 8.5 ° angle of depression, and the binding site of this main wing and fuselage is to be the about 3mm of the slightly inclined to one side side decentre of main wing, so that its fin that presents a side is slightly larger than other flank sheet state; By said structure, the spy can provide a kind of can follow the fly back aerodone structure of original place of circumferencial direction after projection.

The utility model adopts said structure, particularly utilize this fuselage first to embed scarce sewer one elevation angle is arranged, second embed to lack seam then has an angle of depression, and the binding site of this main wing and fuselage is a slightly inclined to one side side, can make its fin that presents a side be slightly larger than other flank sheet state; Gu Te can change its center of flying gravity, and can make it follow the circumferencial direction original place of flying back; Thereby the heading of this aerodone can be controlled by the people, be difficult for losing, more increase the temperament and interest of amusement.

Be the progressive effect that makes further understanding architectural feature of the present utility model place and had, the special conjunction with figs. of this creator is in detail to be illustrated in the back:

Accompanying drawing and label simple declaration:

Fig. 1: be existing aerodone structural representation;

Fig. 2: be member schematic diagram of the present utility model;

Fig. 3: be the utility model fuselage, main empennage angle schematic diagram;

Fig. 4: be front view of the present utility model;

Fig. 5: be of the present utility model group of upright outside drawing;

1 glide body, the 11 hooks breach of pulling

2 fuselages

21 first embed scarce seam

22 second embed scarce seam

23 screw bodies

3 main wings

4 empennages

See also shown in Figure 2, it is a member schematic diagram of the present utility model, it is to constitute aerodone fuselage 2 with the light material cutting, main wing 3 and empennage 4, but in these fuselage 2 leading portions is to be cut with first of setting-in main wing 3 to embed scarce seam 21, but back segment then has second of setting-in empennage 4 to embed lacks seam 22, please and consult Fig. 3 together, first and second of this fuselage 2 embeds and lacks seam 21,22 is to have different luffing angles respectively, wherein, it is to have about 2 ° elevation angle that this first embedding lacks seam 21 its usefulness, second embeds scarce seam 22 then has about 8.5 ° angle of depression, this main wing 3 and empennage 4 are the corresponding respectively scarce seam 21 of first and second embedding that embeds, in 22, in addition referring again to shown in Figure 4, this main wing 3 is the about 3mm of a slightly inclined to one side side decentre with the binding site of fuselage 2, so that its fin that presents a side is slightly larger than other flank sheet state, be to cooperate to be embedded with a screw body 23 in addition in fuselage 2 prow places; Fig. 5 is an of the present utility model group of upright outside drawing.Therefore, please consult shown in Figure 6 again, when using the utility model flight, be by hand-held these fuselage 2 ventral position of centre of gravitys of people and reverse so that fuselage is parallel (it is vertical that main wing is) state of ground, right front projection towards the people, as shown in the figure, it is to illustrate towards right projecting direction, this moment, main wing 3 should be the about 3mm of an inclined to one side side decentre, after projecting, then this aerodone is amesiality because of center of gravity, so promptly make its heading can by tangential direction amesiality and following circumferencial direction smooth-going be back to the original place, thereby can make the people can control the heading of aerodone, aerodone is difficult for losing, and can effectively improve the disappearance that has common structure now, improve the temperament and interest of amusement.

In sum, the utility model " aerodone of the original place of can flying back " has good result of use, thoroughly reforms the scarce fraud of existing structure, really is the innovative design of a novelty, progress and tool practical effect, for trying to achieve the guarantee of legitimate rights and interests, so offer utility application in accordance with the law.
