Description

Technical Field

[0001] The present invention relates to arrows for target shooting competitions.

Background Art

[0002] Target shooting competitions using bows such as archery and Japanese bows, and arrows such as darts and blow darts are dangerous if the arrows accidentally hit a human body or the like.

[0003] As a patent document that discloses a technique for enhancing the safety of arrows, for example, there is Patent Document 1. Patent Document 1 describes an arrow having a flat tip to which a hook-and-loop fastener is attached, and a target having a hook-and-loop fastener attached to its surface. According to the arrow and the target described in Patent Document 1, when an arrow projected by a user hits the target, the arrow adheres to the target, so that the user can confirm the exact position where the arrow hit the target. In addition, since the tip of the arrow described in Patent Document 1 is flat, even if it accidentally hits a human body or the like, the risk of causing an injury or the like is low.

Summary of the Invention

Problems to be Solved by the Invention

[0005] An arrow with a flat tip, like the arrow described in Patent Document 1, has low lethality and is safe, but when it hits and adheres to the target, the area occupying the target is large. Therefore, when the next arrow is projected while the previously projected arrow is adhering to the target, the situation where the arrow hits the arrow adhering to the target and does not adhere to the target easily occurs.

[0006] In view of the circumstances described above, the present invention provides arrows for target practice that offer high safety and allow the user to confirm the exact position where each arrow hit the target, even if the arrows launched earlier and those launched later hit the same or nearby position on the target. [Means for solving the problem]

[0007] To solve the above-mentioned problems, the present invention provides an arrowhead, which is a component that constitutes the tip of an arrow projected towards a target, having a first surface which is the surface that contacts the target when the arrow hits the target, and a second surface which is the surface opposite to the first surface, having a first attachment portion on the first surface that adheres to the target when it comes into contact with the target, having a recess on the second surface into which the tip of the shaft of the arrow is inserted, and having a second attachment portion on the second surface that adheres to the first attachment portion of a different arrowhead of the same type when it comes into contact with the first surface of that arrowhead. [Effects of the Invention]

[0008] Because the arrowhead of the present invention is flat, even if the arrow were to hit a person or other object, the risk of injury is low. Also, when the arrow hits the target, the arrowhead adheres to the target and remains there, allowing the user to confirm the exact position where the arrow hit the target. Furthermore, if a second arrow is projected while the arrowhead of a first arrow that was projected earlier is still attached to the target, and the arrowhead of the second arrow hits the arrowhead of the first arrow that is still attached to the target, the arrowhead of the second arrow will adhere to the arrowhead of the first arrow and remain there, allowing the user to confirm the exact position where the second arrow hit the target. [Brief explanation of the drawing]

[0009] [Figure 1] A diagram showing the appearance of an arrow according to one embodiment. [Figure 2] A diagram showing the structure of an arrowhead according to one embodiment. [Figure 3] A diagram illustrating an embodiment of one of the following. [Figure 4] This figure shows a state in which the first arrowhead is attached to a target according to one embodiment, and the second arrowhead is attached to the tip of the first arrowhead. [Modes for carrying out the invention]

[0010] [Embodiment] Figure 1 shows the appearance of an arrow 1 according to one embodiment of the present invention. Arrow 1 is an arrow for target practice, and more specifically, an arrow for archery. However, arrow 1 may be an arrow for target practice other than archery (for example, a bow such as a Japanese bow, darts, blowgun, etc.).

[0011] The arrow 1 comprises a shaft 11, an arrowhead 12 attached to the tip of the shaft 11, and a plurality of fletchings 13 attached radially near the rear end of the shaft 11.

[0012] The arrowhead 12 is a thin, cylindrical component overall. Figure 2 shows the structure of the arrowhead 12.

[0013] Figure 2(A) is a front view of the first surface of the cylindrical arrowhead 12, which is the surface that contacts the target when the arrow 1 is projected and hits the target.

[0014] Figure 2(B) is a front view of the second bottom surface of the cylindrical arrowhead 12, which is the surface opposite the first bottom surface. The second surface of the arrowhead 12 is provided with a recess O into which the tip of the shaft 11 is inserted.

[0015] Figure 2(C) shows a cross-section of the arrowhead 12 that was cut along the dashed line in Figure 2(B), viewed in the direction of arrow A in Figure 2(B).

[0016] The arrowhead 12 has a thin cylindrical shape overall and comprises a body 120 having a recess O on its second surface (the upper surface in Figure 2(C)), a hook fastener 121 (an example of a first attachment part) attached to the first surface of the body 120 (the lower surface in Figure 2(C)), and a hook fastener 122 (an example of a second attachment part) attached to the second surface of the body 120.

[0017] The material of the main body 120 is, for example, a soft plastic such as vinyl chloride, or an elastic material having a flexural modulus of elasticity of 700 Kg / cm 2 in a steady state as follows.

[0018] The shape of the surface fastener 121 is circular. The shape of the surface fastener 122 is a donut shape with a hole in the concave portion O.

[0019] The surface fastener 121 and the surface fastener 122 are detachable surface fasteners. Hereinafter, it is assumed that the surface fastener 121 is the hook-side surface fastener and the surface fastener 122 is the loop-side surface fastener. However, the surface fastener 121 may be the loop-side surface fastener and the surface fastener 122 may be the hook-side surface fastener. Further, the surface fastener 121 and the surface fastener 122 may be detachable surface fasteners having a male-female distinction with a structure different from that of a hook and a loop. Further, the surface fastener 121 and the surface fastener 122 may be detachable surface fasteners having no male-female distinction.

[0020] FIG. 3 is a view showing the target 2 to be projected by the arrow 1. FIG. 3(A) is a view of the target 2 seen from the front, and FIG. 3(B) is a view of the cross-section of the target 2 cut along the broken line in FIG. 3(A) seen in the direction of the arrow B in FIG. 3(A).

[0021] The target 2 includes a main body 21 which is a flexible sheet-like member or a plate-like member, and a surface fastener 22 attached to the surface of the main body 21.

[0022] The surface fastener 22 is a detachable surface fastener with the surface fastener 121 at the tip 12. Since the surface fastener 121 is the hook-side surface fastener at present, the surface fastener 22 is the loop-side surface fastener. However, for example, when the surface fastener 121 is the loop-side surface fastener, the surface fastener 22 becomes the hook-side surface fastener.

[0023] The user projects arrow 1 (hereinafter referred to as "arrow 1(1)") towards target 2. When arrow 1(1) hits target 2, the hook fastener 121 on the arrowhead 12 (hereinafter referred to as "arrowhead 12(1)") of arrow 1(1) and the hook fastener 22 on target 2 connect to each other, and arrowhead 12(1) adheres to target 2.

[0024] Incidentally, the recess O in the arrowhead 12 is almost the same shape as the tip of the shaft 11, but its size is slightly smaller than the tip of the shaft 11. Therefore, when the tip of the shaft 11 is inserted into the recess O, the shaft 11 and the arrowhead 12 are connected by frictional force.

[0025] The frictional force connecting the shaft 11 and the arrowhead 12 is strong enough that the arrowhead 12 does not separate from the shaft 11 due to its own weight when the user is holding the shaft 11, but weak enough that the part of the arrow 1 excluding the arrowhead 12 (hereinafter referred to as "the body of the arrow 1") separates from the arrowhead 12 due to its own weight when the arrowhead 12 is attached to the target 2.

[0026] Therefore, when arrow 1(1) hits target 2, the body of arrow 1(1) separates from the arrowhead 12(1) attached to target 2, the arrowhead 12(1) remains on target 2, and the body of arrow 1(1) falls to the ground or floor.

[0027] Subsequently, a different arrow (hereinafter referred to as "arrow 1(2)") is projected towards target 2. When arrow 1(2) hits target 2, the hook fastener 121 on the arrowhead 12 of arrow 1(2) (hereinafter referred to as "arrowhead 12(2)") and the hook fastener 22 on target 2 connect to each other, and arrowhead 12(2) adheres to target 2.

[0028] As described above, the user can see the arrowheads 12(1) and 12(2) attached to target 2 and determine the exact position where arrow 1(1) and arrow 1(2) hit target 2.

[0029] Incidentally, there are cases where a subsequent arrow 1 is projected at the same or a similar position as a previously projected arrow 1. For example, suppose that the arrowhead 12(1) of arrow 1(1) is attached to the target 2, and arrow 1(2) is projected towards the target 2, and arrow 1(2) hits the arrowhead 12(1). In this case, the hook fastener 121 of the arrowhead 12(2) of arrow 1(2) comes into contact with the hook fastener 122 of the arrowhead 12(1) that is attached to the target 2. As a result, arrowhead 12(2) becomes attached on top of arrowhead 12(1). The body of arrow 1(2) separates from the arrowhead 12(2) and falls to the ground or floor.

[0030] Figure 4 shows the state in which arrowhead 12(1) is attached to target 2 and arrowhead 12(2) is attached to arrowhead 12(1). Figure 4(A) is a front view of target 2. Figure 4(B) is a view of the cross-sections of target 2, arrowhead 12(1), and arrowhead 12(2) cut along the dashed line in Figure 4(A), in the direction of arrow C in Figure 4(A).

[0031] As described above, with arrow 1 and target 2, users can safely enjoy target shooting competitions. Furthermore, users can accurately determine the position of each arrow that hit the target. Even if multiple arrows hit the same or nearby position on the target, users can accurately determine the position where each of those arrows struck the target.

[0032] Furthermore, it is desirable that the multiple arrowheads 12 used in the competition have different appearances so that it is easy to determine who shot which arrow and which number arrow was shot. Methods for making the appearances of the multiple arrowheads 12 different include coloring at least a part of the arrowhead 12 with a different color, manufacturing at least a part of the arrowhead 12 with a different colored material, or printing identification information such as numbers and symbols on the surface of the arrowhead 12.

[0033] [Differentiation] The embodiments described above are specific examples of the present invention and can be modified in various ways within the scope of the technical idea of ​​the present invention. Examples of such modifications are shown below. Two or more of the following modifications may be combined as appropriate.

[0034] (1) In the embodiment described above, the target 2 and the arrowhead 12 are detachably connected by a hook-and-loop fastener. The target 2 and the arrowhead 12 may also be detachably connected by a connecting mechanism other than a hook-and-loop fastener.

[0035] For example, the arrowhead 12 may have a layer of adhesive gel-like substance (so-called sticky slime) on its first surface instead of the hook-and-loop fastener 121. In this case, the target 2 will have a flexible sheet-like member or plate-like member having a smooth surface to which the adhesive gel-like substance can be detachably attached, instead of the hook-and-loop fastener 22. Also, the arrowhead 12 may have a flexible sheet-like member or plate-like member having a smooth surface to which the adhesive gel-like substance can be detachably attached, on its second surface instead of the hook-and-loop fastener 122, similar to the target 2.

[0036] Alternatively, the target 2 may be provided with a layer of adhesive gel-like material instead of the hook-and-loop fastener 22, the arrowhead 12 may be provided with a flexible sheet-like member or plate-like member having a smooth surface on its first surface instead of the hook-and-loop fastener 121, and the arrowhead 12 may be provided with a layer of adhesive gel-like material on its second surface instead of the hook-and-loop fastener 122.

[0037] Furthermore, for example, the arrowhead 12 may have a magnet on its first surface, instead of a hook-and-loop fastener 121, with its surface covered with an elastic material (cushioning material) such as silicon. In this case, the target 2 will have a flexible sheet-like member or plate-like member containing a magnetic material such as iron instead of a hook-and-loop fastener 22. Also, the arrowhead 12 may have a flexible sheet-like member or plate-like member containing a magnetic material such as iron on its second surface, instead of a hook-and-loop fastener 122, similar to the target 2.

[0038] Furthermore, the magnetic material on target 2 and the magnetic material on the second surface of arrowhead 12 may be magnets of opposite polarity to the magnet on the first surface of arrowhead 12.

[0039] (2) The shapes, sizes, etc. of the arrow 1 and target 2 shown in the figures used in the description of the above-described embodiment are examples and may be changed as desired. For example, the arrowhead 12 is shown to be cylindrical, but it may be hexagonal, rectangular, or the like. Also, in the above-described embodiment, the shape of the tip of the shaft 11 (and the corresponding recess O) is a frustoconical shape, but other shapes may be adopted. [Explanation of Symbols]
