Description

  The present invention relates to the technical field of coffins, and in particular to a foil-type sports kite.

  Heretofore, sports kites (sports kites) that can be freely controlled, such as up and down, left and right, and further rotation, have gained popularity in Japan.

  There are various types of sports kites, but among them, the so-called "foil type" sports kites do not have a frame (bone) structure in the kite body and fly lightly and are dangerous from collisions. Because it has less sex, it is popular as a leisure as well as competitions.

  As shown in FIG. 11, the foil-type sports kite has a structure in which each cell constituting the kite body 100 is inflated by air that has been received by the wind and entered from the air intake port 140, and floats in the air in that state. There is. A large number of support lines 150 are connected from the main body 100, and the support lines 150 are combined into four operation lines 160, and the four operation lines 160 are connected to both ends of the two handles 200. Configured

  The operator freely manipulates the kite by pushing and pulling the handle 200 and further tilting it.

  In addition, such foil-type sports kites are also available as finished products and commercially available, and can be purchased and enjoyed by anyone immediately (see Non-Patent Document 1).

  However, what is marketed as in Non-Patent Document 1 is expensive depending on the product, and it is not always easy for children to play.

  In addition, the pleasure of self-made, and the knowledge obtained by self-making while trial and error, etc. are points that can not be absolutely obtained simply by purchasing and using a finished product.

  That said, if a process to sew using a special fabric such as sail is needed, it will be expensive and it will not be possible to assemble it more easily.

  The present invention has been made to solve these problems, and it is an object of the present invention to provide a foil-type sports kite body structure that can be assembled at low cost and with simple operations and procedures.

  In order to solve the above problems, the present invention is a main body structure of a foil type sports kite composed of a plurality of cells, and each cell is affixing a lower surface sheet made of a resin film and an upper surface side sheet made of a resin film And the upper surface side sheet is divided into a plurality of cells corresponding to at least one of the lower surface side sheets, and is affixed to the lower surface side sheet. Each of the cells is formed into a bag shape.

  With this configuration, it has become possible to provide a foil-type sports kite body structure that can be assembled at low cost and with simple operations. First, by using resin film (polyethylene film etc.) widely used as a material for garbage bags etc., it achieves overwhelming cost reduction and repairs easily even in the event of breakage etc. Is possible.

  In addition, because resin films can be made by sticking together using adhesive tape etc., the work of sewing etc. becomes unnecessary and even a small child can make it enough to make it with a level that can be made with a little effort. It is simplified.

  In addition, the upper surface side sheet is divided by the number of cells, that is, the upper surface side sheet is configured by sticking an independent sheet (upper surface divided sheet) for each cell to the lower surface side sheet. The upper surface side sheet (upper surface divided sheet) which has received the wind is easily bent so as to expand, and as a result, each cell is expanded to easily generate lift.

  The upper surface side sheet may be attached to the lower surface side sheet in a state of being slackened in the width direction.

  According to this structure, it is possible to realize a structure in which the cell is more easily air-sealed.

  Further, the amount of slack in the width direction is largest in the vicinity of the front end with the intake port, and gradually decreases toward the rear end side, and also decreases slightly toward the front end from the vicinity of the front end It may be configured.

  According to this structure, the airflow flowing above and below the expanded cell is likely to generate lift, and a foil-type sports kite that flies well can be realized.

  In addition, the lower side sheet may be divided into two or more and formed into a block.

  According to this structure, the manufacture is facilitated, and even when a part is damaged, the entire part can be returned to the state without damage or the like by replacing only the part.

  The present invention is a method of manufacturing a main body of a foil-type sports kite composed of a plurality of cells, wherein a resin film made of a resin film and divided by the number of cells with respect to a sheet made of a resin film is used. A method of manufacturing a main body of a foil-type sports kite by sequentially applying an upper surface side sheet, and further, the lower surface side sheet is divided into two or more blocks and is formed into a block. It is also possible to grasp as the method of manufacturing the main part of the foil type sports kite by bonding the upper surface side sheet and manufacturing a plurality of blocks and then connecting the blocks.

  By applying the present invention, it is possible to provide a foil-type sports kite body structure that can be assembled at low cost and with simple operations and procedures.

  Hereinafter, with reference to the accompanying drawings, the description will be added to a body 100 of a foil type sports kite which is an example of an embodiment of the present invention. It should be noted that in order to facilitate understanding of the drawings, there are parts in which the size and dimensions of each part are expressed in an exaggerated manner, and there are parts that do not necessarily match the actual product. Also, each drawing shall be viewed in the direction of the reference numerals.

<Structure of the body of a foil type sport kite>
As shown in FIG. 1, the foil type sports kite 10 comprises a main body 100, a large number of support lines 150 connected from the main body, four operation lines 160 for joining the support lines 150, The two handles 200 to which the book operation line 160 is connected are configured as main components. In addition, what is drawn in the approximate center of FIG. 1 is "winding".

  In the specification and claims, the “lower surface” of the foil-type sports kite body 100 faces the side provided with the support lines 150, that is, toward the operator when lifting the sports kite. The "upper surface" means the opposite surface. Furthermore, “front” refers to the side provided with the air intake 140 that receives wind, and “rear” means the opposite side.

  The present invention relates to the main body 100 constituting the foil-type sports kite 10, and hence the following description will be focused on the main body 100.

  As shown in FIG. 2, the main body portion 100 is configured by the lower surface side sheet 110 and the upper surface side sheet 120. The material of each sheet is made of a resin film (for example, a polyethylene film). Further, as viewed from the lower surface side as shown in FIG. 2, the main body portion 100 has a configuration in which six vertically long cells C1 to C6 are arranged in the width direction (left and right direction).

  At the front end (upper in FIG. 2) of each of the cells C1 to C6, that is, at the front end of the main body 100, an air inlet 140 is provided, and the received wind enters the main body 100 from this portion. The cells C1 to C6 are configured to expand.

  As shown in FIG. 3, in the main body portion 100 shown as an example of the embodiment of the present invention, the lower surface side sheet 110 is configured of three lower surface divided sheets 111 to 113. Similarly, the upper surface side sheet 120 is composed of six upper surface divided sheets 121 to 126.

  As apparent from FIGS. 1 and 2, when the upper surface divided sheets 121 to 126 are superimposed on the lower surface divided sheets 111 to 113, the upper surface divided sheets 121 to 126 pop out slightly forward (front end side) on the front end side. Configured This is a device for making it easy to receive the wind and to easily introduce the received wind into the cells C1 to C6.

  Thus, the main body portion 100 shown as an example of the embodiment of the present invention has a configuration in which two upper surface division sheets 121 to 126 correspond to one lower surface division sheet 111 to 113. Collectively, blocks X to Z are formed.

  In addition, the shape of a top surface division | segmentation sheet | seat is supplementarily demonstrated more concretely, referring FIGS. 9-10.

  An actual top divided sheet has, for example, a shape as shown in FIG. 9 (a). The width W2 of a position near the front end (left side in FIG. 9A) (in the present embodiment, around the cut end of the front end notch 123a) is smaller than the width W1 of the rear end (right side in FIG. 9A). Configured to be large. As a result, when the lower surface division sheet 112 is attached, the amount of slack at the rear end side is smaller than that at the front end side.

  Further, as shown in the figure, a front end notch 123a is provided, and this notch 123a is overlapped with the lower surface divided sheet 112 to form a bag shape (see FIG. 9B and FIG. 10). It will be finished as a slightly bowed shape as it goes. This unique cell shape makes it possible to construct the body of a foil-type sports kite that flies well and is easy to obtain lift.

<Procedure of making body of foil type sport kite>
Subsequently, how to make the main body 100 will be described with reference to FIGS. 2 to 8.

  The lower surface division | segmentation sheets 111-113 and the upper surface division | segmentation sheets 121-126 use what is previously cut by the predetermined | prescribed size (size).

  First, as described in FIG. 3, a reinforcing tape (such as a masking tape) 170 is stretched and reinforced on the front end portions of the lower surface divided sheets 111 to 113 and the upper surface divided sheets 121 to 126. Each parting sheet is pressed with caution so as not to move and pasted, and the part which has been overstretched is cut with scissors or a cutter.

  Next, two upper surface division sheets are attached to one lower surface division sheet to form a block (three blocks X to Z in the present embodiment).

  Here, as shown in FIG. 4, a procedure of forming the block X by sticking two upper surface divided sheets 121 and 122 to one lower surface divided sheet 111 will be described. In addition, although the upper surface division | segmentation sheet 121 is attached to the left half of the lower surface division | segmentation sheet 111, and the upper surface division | segmentation sheet 122 is attached to the right side of the lower surface division | segmentation sheet 111, it becomes a fixed position.

  As shown in FIG. 5A, first, the lower surface divided sheet 111 is placed on a floor surface or the like, the upper surface divided sheet 121 is placed upside down on the reverse side (right side), and attached using an adhesive tape 300. .

  After that, as shown in FIG. 5 (b), the stuck upper surface divided sheet 121 is returned to the left (the original fixed position side), and another upper surface divided sheet 122 is further overlaid thereon (turned over). Then, the adhesive tape 300 is used for sticking.

  Then, as shown in FIG. 6, the top surface division sheet 122 which has been stacked later is returned to the right (the original fixed position side). Furthermore, the width direction edge of the side on which the upper surface divided sheets 121 and 122 are not attached is positioned slightly inward from both ends (left and right ends) of the lower surface divided sheet 111 and attached and fixed with the adhesive tape 300. The wide adhesive tape 302 is further affixed from above to reinforce the boundary between the two top divided sheets 121 and 122 from above.

  In addition, about the part which will become the both ends of the main-body part 100 finally, after sticking and fixing with the adhesive tape 300, as shown in the enlarged view part of FIG. Attach and reinforce at 302. The end face connected to the other block does not reinforce this fold.

  Further, in the present embodiment, since the upper surface divided sheets 121 and 122 are configured to be wider than the corresponding portion (half area) of the lower surface divided sheet 111, as shown in FIG. The configuration is such that the lower surface division sheet 111 is slackened (floating). Air flows into the part of the slack (floating) and the cell is expanded. In FIG. 6, the degree of slack (floating) is exaggerated and expressed for easy understanding.

  The slack amount (lifting amount) of the upper surface divided sheet with respect to the lower surface divided sheet 111 is largest in the vicinity of the front side (intake port 140 side) and gradually decreases toward the rear end side, and from the front end vicinity to the front end It is configured to be slightly smaller toward (the inlet 140 side). For example, in FIG. 3A, the upper surface divided sheets 121 to 126 are expressed as sheets of equal width from the top to the bottom for easy understanding, but strictly speaking, they gradually become wider from the bottom to the top Configured (this point will be described in more detail later).

  In a similar procedure, two upper surface sheets 123 and 124 are attached to the lower surface sheet 112. Further, two upper surface sheets 125 and 126 are attached to the lower surface sheet 113.

  Thereby, as shown to Fig.7 (a), three blocks XZ are completed. Finally, as shown in FIG. 7 (b), three blocks X to Z are connected and attached with an adhesive tape to complete one main body part 100.

  Also, as shown in FIG. 8, the upper surface divided sheet and the lower surface are divided to form the rear end portion of each block X to Z, that is, the portion to be the bottom for forming the cells C1 to C6 into a bag shape. Stick and fix the sheet. Once the upper surface division sheet 122 is adhered and fixed to the lower surface division sheet 111 with the adhesive tape 300 also for the relevant portion, the adhered adhesive tape 300 is folded so as to be folded in half, and the adhesive tape 302 is further adhered to reinforce it. Keep it.

  Through this procedure, the main body 100 is completed.

  Thus, this invention is a structure of the main body 100 of the foil type | mold sport kite comprised from several cell C1-C6, Comprising: Each cell C1-C6 is resin film lower surface side sheet 110 and resin film make The upper surface side sheet 110 is attached to the upper surface side sheet 110 so that the upper surface side sheet 110 is formed of a plurality of cells with respect to at least one lower surface side sheet 110 (three divisions in the above example). Each of the cells C1 to C6 is formed in a bag shape by being divided (six divisions in the above example) and attached to the lower surface side sheet 110.

  This configuration makes it possible to provide the structure of the main body 100 of the foil-type sports kite that can be assembled at low cost and with a simple operation. First, by using resin film (polyethylene film etc.) widely used as a material for garbage bags etc., it achieves overwhelming cost reduction and repairs easily even in the event of breakage etc. Is possible.

  In addition, since sheets made of resin film can be made by sticking them to each other using adhesive tapes 300, 302, etc., work such as sewing becomes unnecessary, and even small children can be made enough if they work a little The manufacturing method is simplified to the next level.

  In addition, the upper surface side sheet 120 is divided by the number of cells C1 to C6, that is, the upper surface side sheet 120 is an independent sheet for each cell (upper surface divided sheets 121 to 126) with respect to the lower surface side sheet 110 By being stuck and configured, the upper surface divided sheet that receives the wind is easily bent so as to expand, and as a result, each of the cells C1 to C6 is expanded and has a structure that easily generates lift.

  The upper surface divided sheets 121 to 126 are attached to the lower surface side sheet 110 in a state of being slackened in the width direction.

  With such a configuration, the cells C1 to C6 receive the air and realize a structure that is easily expanded.

  Further, the amount of slack in the width direction is largest in the vicinity of the front end where the intake port 140 is located, and gradually decreases toward the rear end side, and also decreases slightly from the vicinity of the front end toward the front end Was configured.

  Due to such a configuration, the air flow flowing up and down the expanded cells C1 to C6 easily generates lift force, and realizes a foil type sports kite that flies well.

  In addition, the lower surface side sheet is divided into two or more blocks to facilitate the production, and even when a part is broken, the entire part is damaged by replacing only that part. It is configured to be able to return to the non-existent state (It is sufficient to peel off the adhesive tape and replace the damaged block). Further, by increasing or decreasing the number of blocks, there is also an advantage that it is easy to easily configure variations of main portions different in size in the width direction.

<Other configuration example>
In the above, although the main-body part 100 was comprised by six cells C1-C6, the number of cells is not restricted to this. It is possible to change suitably according to a user's physical strength, a purpose, etc.

Moreover, in the above, although the lower surface side sheet | seat 110 was comprised as the lower surface division | segmentation sheet | seat divided | segmented into three sheets, it is not restricted to this . It is also possible to configure a 2-minute split, and so on.
