Description

  The present invention relates to a string-like member capable of easily creating a soccer field.

  In creating a soccer field, it is necessary to draw the touch line, the goal area, and the penalty area line in a direction perpendicular to the goal line (see FIG. 9A for the soccer field). Therefore, a method for measuring the right angle using the Pythagorean theorem is known.

  Usually, in the work of creating a soccer field, a right angle is measured by forming a right triangle using three tape measures of 30 m, 40 m, and 50 m using three tape measures. Therefore, it was necessary to prepare a plurality of tape measures.

In addition, a string-like member is known in which one string-like member is bent to form a right triangle. For example, Patent Document 1 describes a string that forms a right triangle in a rectangular section forming device for forming a rectangular coat such as baseball diamond. Patent Document 2 describes a configuration that includes a band A, B, and C that are right-angled rulers that are convenient for carrying and that form sides of a right-angled triangle. Patent Document 3 describes a baseball tape measure in which three mark points are displayed and the distance ratio between the points is set so as to satisfy the Pythagorean theorem.
However, when creating a soccer field, it is necessary to measure different lengths such as a goal area, a penalty area, etc. (see FIG. 9A. In the full court, (1) 5.5 m, (2) 11 m, (3 ) 16.5m, (1) 4m, (2) 8m, (3) 12m in a boy's half-size coat.) In the conventional string-like member forming a right triangle, a right angle can be measured, but the length needs to be measured separately from the right angle measurement, for example, with a different tape measure.

Patent Document 4 describes a rope that forms two right isosceles triangles from the inside of a goal post, which is a ruler for creating a soccer field. With this ruler, the size of the goal area and penalty area can be measured while measuring the right angle.
However, since the two right-angled isosceles triangles are formed, the ropes are branched, easily entangled, and the usability and storage property are poor.

  Hereinafter, embodiments of a string-like member according to the present invention and a right-angle measuring method using the same will be described in detail with reference to the drawings.

FIG. 1 is a schematic explanatory view showing the configuration of the string-like member 11 of the first embodiment of the present invention.
The string-like member 11 is a string-like member composed of the string part 3 having the end parts 2 and 2 ′. An intersection mark X1 is provided at one end of the end portion (on the end portion 2 side) as a mark serving as an intersection when the string-like members are crossed to form a ring structure, and the other end of the end portion (end portion 2). On the “side”, an intersection mark X2 is provided as a mark serving as the other intersection.

Further, the string-like member 11 is provided with three points of a corner mark A, a corner mark B, and a corner mark C. When a ring structure is formed by intersecting the intersection mark X1 and the intersection mark X2, a corner structure is formed. The length a between the corner mark A and the corner mark B, the length b between the corner mark B and the corner mark C, and the length c between the corner mark C and the corner mark A are expressed by the following formulas: It is configured to satisfy (1).
Formula (1) a ² = b ² + c ²

  In addition, as for the dimension of the string-like member 11 of the first embodiment, the length b is 5.5 m, the length c is 11 m, and the length a is 12.3 m (5.5 × route 5).

  In the string-like member 11 of the first embodiment, the position of the cross mark X1 is provided at the end 2 and the cross mark X2 is provided at the end 2 ′. You may provide in any of an edge part and a string part. If the intersection mark is provided at the end, the process of attaching the intersection mark can be omitted, and the number of marks is reduced, so that the string-like member has a simple structure.

When two cross marks are provided at both ends of the string-like member, the string-like member of the present invention has a very simple structure, and therefore, a string-like member that is easy to use and excellent in workability can be provided. .
Also, when one of the two cross marks is provided at one end of the end and the other of the cross marks is provided at the string portion, the length of the string member is extended to the other end of the string member. Since an extension region can be provided, a function for long measurement can be added.

Further, in the string-like member 11 of the first embodiment, the intersection mark X1 and the corner mark B are provided at the same position. Thereby, since the intersection mark X1 and the corner mark B can be combined into one point, the step of printing the mark can be omitted, and furthermore, the number of marks on the string-like member is reduced, so that the structure is simple. Can do.
In addition, any of A, B, or C may be sufficient as the corner | angular part mark which can be provided in the same position as one intersection mark.

  Furthermore, by providing the intersection mark X1 and the corner mark B at the same position, the string portion BC (5.5m) and the string portion CA (11m) are connected to each other, from the corner mark B to the corner mark A. Becomes 16.5 m. Since 16.5 m is the same length as the vertical line of the penalty area, the length of the vertical line of the penalty area can be easily measured (see FIG. 7 (4)). Note that the same effect can be obtained even if the corner mark provided at the same position as one of the intersection marks is A.

  The material of the string-like member is a material that can be bent and hardly expands or contracts even when a tensile force is applied. For example, it is made of a resin material such as polyfiber, a glass fiber material such as glass fiber, metal, cloth, or the like. Metal objects have a risk of cutting their hands during work, and cloth objects require a large number of yarns to be knitted in order to increase the tensile strength, resulting in an increase in weight. Therefore, a highly safe and lightweight resin material or glass fiber material is preferable. Glass fiber materials are particularly preferred because they are less stretchable due to temperature changes.

  The shape of the string-like member may be any shape, but for example, there is a belt-like shape, a cylindrical shape, a prismatic shape, or a chain shape. From the viewpoint of easy processing for printing the mark and easy viewing of the scale for measuring the long dimension, a belt-like one is preferable.

The intersection marks X1, X2 and the corner marks A, B, C may have any configuration as long as their positions are known, and may be a clip, a seam, a tag, or the like in addition to a paint such as ink. Further, when the position of each mark is the end 2 or 2 ′ of the string-like member, the mark can be omitted.
Moreover, you may comprise two cross marks by the connection member which connects each.

  The corner marks A, B, and C are preferably fixing members that can be fixed to the ground. The fixing member may be a member that is indirectly fixed using a peg prepared separately, such as a ring-shaped member, in addition to a member that is directly fixed, such as a peg. By using the corner mark as a fixing member, it is not necessary to form a right triangle by a plurality of workers when measuring a right angle.

The fixing member is preferably a ring-shaped member. By setting it as a ring-shaped member, it can be set as a simple fixing member.
Furthermore, the string-like member can be easily bent at the positions of the corner marks A, B, and C by connecting the periphery of the ring-like member to be rotatable.

  Further, when one of the intersection marks is set at the same position as the corner mark of the ring-shaped member, the other intersection mark is preferably a ring-shaped member. Accordingly, the pegs can be passed through the two intersection marks and easily connected.

The shape of the ring-shaped member may be any shape such as a circular shape or a polygonal shape. A circular shape is preferable from the viewpoint of easy rotation.
The material of the ring-shaped member may be any material as long as it is excellent in tensile strength, and examples thereof include resin and metal.

The intersection marks X1, X2 and the corner marks A, B, C are preferably different in color and shape, and only the corner mark C forming a right angle is preferably different in color and shape from the other marks. preferable. By making the corner mark C have a different color and shape, the corner mark that is a right angle can be seen at a glance, and a string-like member having excellent workability can be provided.
When the ring-shaped members having different shapes are used, the corner mark C is preferably a regular square so that the string part BC and the string part CA can easily form a right angle.

  Moreover, it is preferable that the color of the string part between AB, the string part between BC, and the color of the string part between CA are different colors. Thereby, since it can be understood at a glance which length each string part is, a string-like member excellent in workability can be provided.

  In addition, it is preferable that the string-shaped member of the present invention has a long dimension measurement scale. When attaching the scale for long dimensions, it is preferable to attach both the dimension between each corner mark and the total dimension from the end. The dimensions may be displayed in either the metric system or the yard / pound system.

Further, an arc mark Q is marked on the string-like member 11 at a position 9.15 m from the corner mark A in the cross mark X2 direction. In the full coat, the radius of the penalty arc and the center circle is 9.15 m. By providing the arc mark Q, a penalty arc and a center circle can be easily drawn using the string-like member of the present invention.
The arc mark Q may be based on any one of the corner marks A, B or C and the intersection marks X1 and X2. However, as in the first embodiment, the arc mark Q extends from the corner mark A to the intersection mark X2 ( It is preferably provided at a position in the end portion 2 ′) direction of 9.15 m. According to this configuration, after the penalty mark is positioned, the penalty arc can be drawn with the corner mark A as an axis as it is, so that the workability is excellent.
In the soccer field, the radius of the center circle and the penalty arc is 9.15 m for the 11-person system (full court) and 7 m for the 8-person system (half-size court).

In addition, a goal center measurement mark P is marked on the string-like member 11 at a position 3.66 m from the corner mark C in the corner mark B direction. 3.66 m corresponds to ½ of the goal size of the full court size (distance between goal posts: 7.32 m). That is, when positioning the penalty mark, the corner mark C can be placed at the center of the goal by aligning the mark P with the position inside the goal post.
In the case of a half-coating size goal (distance between goal posts: 5 m), a mark P may be added at a position 2.5 m from the corner mark C in the corner mark B direction.

Although not shown in the figure, the scale from the corner mark B to the corner mark C and the dimension from the corner mark C to the corner mark A are marked. In addition to these dimensions, the total dimension from the end 2 to the end 2 ′ is also graduated.
Further, an arc mark Q is attached to the string portion between the corner mark C and the corner mark A at a position 9.15 m from the corner mark C.

The corner mark B (intersection mark X1), the corner mark A, and the intersection mark X2 are configured by a circular ring-shaped member 5, and the corner mark C is configured by a square ring-shaped member 5 ′. Thereby, when forming the right triangle, the corner mark C forming the right angle of the right triangle can be distinguished at a glance.
Furthermore, in each mark, the string-like member is rotatably connected to the ring-like member. With this configuration, the corners can be easily bent when forming a right triangle.

  In addition, the color of the string portion between the corner mark B and the corner mark C and the color of the string portion between the corner mark C and the corner mark A are different from each other. For example, the string part between the corner mark B and the corner mark C is red, the string part between the corner mark C and the corner mark A is yellow, and the string part from the corner mark A to the end 2 ′ is white. Configure. Thereby, a 5.5 m string part (between the end part 2 and the corner mark C) and an 11 m string part (between the corner mark C and the corner mark A) can be distinguished at a glance.
