Description

[Technical Field]

[0001] The present invention relates to a volleyball training tool. [Background technology]

[0002] There has long been a training tool in existence that involves a pair of poles attached to a pair of posts with a ball game net, a rope stretched between the top ends of the poles, and the gap between the rope and the top end of the net being used as a target for practicing ball control, such as serving (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3165715 Summary of the Invention [Problem to be solved by the invention]

[0004] In volleyball, a blocking form that minimizes preparatory movements such as tilting the ball and quickly reaching over the top of the volleyball net toward the opponent is considered desirable. However, existing volleyball training equipment for practicing blocking form has the problem of not being able to effectively reduce preparatory movements.

[0005] To provide a volleyball training tool that enables a player to learn a desirable blocking form by reducing preparatory movements such as tilting movements and quickly reaching his / her hand over the top of a volleyball net to the opponent. [Means for solving the problem]

[0006] The volleyball training equipment of the present invention comprises a pair of support members attached to a volleyball net stretched to a predetermined height, and a guide line member having elasticity and attached between the pair of support members, wherein the guide line member is tensioned parallel and horizontally to the volleyball net, the support member includes a fastening means for detachably fastening the support member to a strip-shaped upper end portion attached to the upper end of the volleyball net, and the support member separates the guide line member from one surface of the volleyball net in an out-of-plane direction, forming a gap between the guide line member and one surface of the volleyball net.

[0007] With the volleyball training tool of the present invention, by practicing putting one's hand through the gap formed between the guide line member and the volleyball net, one can learn a good blocking form by reducing preparatory movements such as tilting the ball and quickly reaching one's hand over the top of the volleyball net to the opponent.

[0008] Furthermore, it is preferable that the support member has an abutment surface that abuts against the upper end when fixed to the upper end by the fixing means, and the vertical length of the abutment surface is equal to the vertical width of the upper end.

[0009] According to this configuration, the vertical length of the contact surface of the support member is equal to the vertical width of the upper end, so that the support member that tensions the guide line member is supported in a stable position by the contact surface.

[0010] Preferably, the support members each have opposing sides that face each other and an opposite side to the opposing sides, and the fastening means is provided on the opposite side.

[0011] According to this configuration, the fixing means not only fixes the support member to the upper end portion, but also suppresses rotation of the support member caused by contraction force due to the elasticity of the guide line member tensioned in a horizontal state.

[0012] The support member preferably has a height adjusting means for adjusting the installation height of the guide line member.

[0013] According to this configuration, by adjusting the installation height of the guide line member, the support member can adjust the difficulty of practicing reaching over the top of the volleyball net to the opponent, thereby correcting the block form to a desirable one.

[0014] The support member preferably has a gap adjusting means for adjusting the size of the gap by changing the interval at which the guide line members are disposed.

[0015] According to this configuration, the support member adjusts the size of the gap between the guide line member and the volleyball net, thereby adjusting the difficulty of the practice of reaching over the top of the volleyball net to the opponent, and correcting the block form to a desirable one.

[0016] In addition, it is preferable that the fastening means is a fastening slot that is formed integrally with the support members and opens from the opposing sides of the support members to the opposite side of the opposing sides, and is provided on the inside side of the support members closest to the volleyball net and at the lower end side of the support members.

[0017] According to this configuration, the fastening slots formed integrally with the support member are provided on the lower end side of the support member, and function as fastening means for fastening the support member to the upper end. Therefore, the fastening means can be provided on the support member simply by forming the shape of the support member, thereby reducing the manufacturing cost of the volleyball training equipment.

[0018] It is also preferable that the fastening slot is composed of a guide portion that opens in a tapered shape, a holding portion that holds the portion of the upper end through which the upper cable of the volleyball net passes, and a passage portion that connects the guide portion and the holding portion.

[0019] With this configuration, the upper end of the volleyball net is guided by the guide portion into the fastening slot, passes through the passage portion, and reaches the retaining portion at the back of the fastening slot. The retaining portion holds the upper end of the portion through which the upper cable passes, allowing the support member to be stably secured to the upper end of the volleyball net.

[0020] Furthermore, it is preferable that the support member further includes a winding slot that opens from the opposing side to the opposite side and is integrally formed with the support member, and that the winding slot is provided on the outside side of the support member that is away from the volleyball net and on the upper end side of the support member.

[0021] According to this configuration, the winding slot is simply formed in the shape of the support member, which not only makes it easy to install the guide line member, but also reduces the manufacturing cost of the volleyball training equipment. [Effects of the Invention]

[0022] From the above, the volleyball training equipment of the present invention can provide a volleyball training equipment that reduces preparatory movements such as tilting and allows players to learn a good blocking form, in which they quickly reach over the top of the volleyball net toward their opponent.

[0024] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same reference numerals are used to denote the same components, and the description thereof will be omitted.

[0025] First, a first embodiment of the present invention will be described. Fig. 1 is a perspective view showing a volleyball training tool 1 according to the first embodiment of the present invention. Fig. 2 is a front view showing the volleyball training tool 1 shown in Fig. 1 installed on a volleyball net 9. The volleyball training tool 1 shown in Figs. 1 and 2 includes a pair of support members 2, 2 attached to the volleyball net 9 tensioned to a predetermined height, for example, a height in accordance with the rules of volleyball, and a guide line member 3 provided between the support members 2, 2.

[0026] An upper cable 92 and a lower rope 93 are attached to both ends of the volleyball net 9. The upper cable 92 and the lower rope 93 are attached to a pair of support posts 91, 91 spaced a predetermined distance apart, thereby tensioning the volleyball net 9. Note that the location where the volleyball net 9 is installed does not have to be between the support posts 91, 91, as long as the volleyball net 9 can be tensioned to a predetermined height.

[0027] The support members 2,2 include fastening means 20 for removably fastening the support members 2,2 to the upper end portion 90 of the volleyball net 9. The support members 2,2 are preferably provided inside the side bands 94,94 provided at both ends of the volleyball net 9, i.e., at the upper end portion 90 inside the side lines of the volleyball court. The support members 2,2 may also be provided at the upper end portion 90 outside the side bands 94,94.

[0028] The fastening means 20 may be, for example, a pair of belts whose base ends are fixed to the support members 2, 2 by adhesive bonding or sewing with thread, and whose tips are provided with a pair of male and female hook-and-loop fasteners. Note that the fastening means 20 is not limited to the above-described configuration, as long as it can detachably fasten the support members 2, 2 to the upper end portion 90.

[0029] The guide line member 3 is an elastic wire, for example, a stretchable rubber cord, and both ends of the guide line member 3 are wound around height adjustment means 24 of the support members 2, 2, which will be described later. The guide line member 3 is tensioned between the support members 2, 2, parallel and horizontal to the volleyball net 9.

[0030] The support members 2, 2 are provided with abutment surfaces 21 that come into contact with the upper end portion 90 when the support members 2, 2 are fixed to the upper end portion 90 by the fixing means 20. When the guide line member 3 is tensioned between the support members 2, 2, a contraction force is generated due to elasticity. When the abutment surfaces 21 come into contact with the upper end portion 90, displacement of the support members 2, 2 due to the contraction force is reduced. It is preferable that the vertical length of the abutment surfaces 21 is equal to the vertical width of the upper end portion 90, and by having the vertical length of the abutment surfaces 21 equal to the vertical width of the upper end portion 90, the fixation to the upper end portion 90 by the fixing means 20 or the like is strengthened. As a result, the support members 2, 2 are provided in a stable position relative to the upper end portion 90 by the abutment surfaces 21.

[0031] The support members 2, 2 are provided with opposing sides 22 that face each other and an opposite side 23 located opposite the opposing side 22, and the fastening means 20 is provided on the opposite side 23. When the fastening means 20 fastens the support members 2, 2 to the upper end portion 90, the guide line member 3 is tensioned between the support members 2, 2 in a manner that is parallel and horizontal to the volleyball net 9. At this time, a contracting force due to elasticity acts, and the support members 2, 2 around which the guide line member 3 is wound are pulled inward.

[0032] If the fastening means 20 is provided on the opposing side 22 located between the support members 2,2, the fastening means 20 cannot resist the contraction force acting on the support members 2,2, and the support members 2,2 are pulled inward and rotated.

[0033] In contrast, if the fixing means 20 is provided on the opposite side 23 located opposite the opposing side 22, even if a contraction force acts on the support members 2, 2, the fixing means 20 is located on the opposite side in the pulling direction, and therefore rotation of the support members 2, 2 is suppressed. Furthermore, even if an external force greater than the contraction force is applied to the guide line member 3, for example, when the user's hand H gets caught on the guide line member 3 during practice and a force pulling it inward is applied to the guide line member 3, rotation of the support members 2, 2 is suppressed.

[0034] As a result, the fixing means 20 not only fixes the support members 2,2 to the upper end portion 90, but also suppresses rotation of the support members 2,2 caused by contraction force due to the elasticity of the guide line member 3 tensioned in a horizontal state.

[0035] Fig. 3 is a plan view of the volleyball training equipment shown in Fig. 1. As shown in Fig. 3, the support members 2, 2 separate the guide line member 3 from one surface of the volleyball net 9 in an out-of-plane direction, forming a gap 4 between the guide line member 3 and one surface of the volleyball net 9.

[0036] Next, block practice using the volleyball training tool 1 according to the present invention will be described. Fig. 4 is a schematic diagram showing the trajectory of a user's hands when performing block practice using the volleyball training tool 1 shown in Fig. 1. Fig. 5 is a schematic diagram showing the trajectory of a user's hands when performing block practice without using the volleyball training tool 1.

[0037] Normally, when performing block practice without being conscious of it, a user (not shown) often follows a swing trajectory Ta in which the user jumps from a point away from the volleyball net 9 and extends their hand H toward the opponent, as shown in Figure 5. As shown in Figure 5, the swing trajectory Ta follows an arc, so the time from when the user jumps until when they extend their hand H toward the opponent becomes long.

[0038] When the volleyball training tool 1, which forms a gap 4 between the guide line member 3 and one surface of the volleyball net 9, is attached to the volleyball net 9 and the user practices blocking while consciously passing the hand H through the gap 4, the user can follow a thrust trajectory T in which the user jumps from a point close to the volleyball net 9 and extends the hand H in a straight line toward the opponent, as shown in Figure 4. In this way, the volleyball training tool 1 can provide practice for mastering a desirable block form that shortens the time from when the user jumps until when the user extends the hand H toward the opponent.

[0039] The volleyball training tool 1 has various means for adjusting the difficulty of the block training in which the user reaches out to the opponent beyond the top of the volleyball net in order to gradually correct the user's block form from the tilt trajectory Ta to the thrust trajectory T.

[0040] As shown in Figure 1, the support members 2, 2 are provided with height adjustment means 24 for adjusting the installation height of the guide line member 3. The height adjustment means 24 is, for example, a convex portion with notches or markings every centimeter (cm). When the height adjustment means 24 sets the installation height of the guide line member 3 higher than the height of the top end of the volleyball net 9, the front-to-back width of the gap 4 becomes wider from the user's perspective.

[0041] When the front-to-back width of gap 4 is wider from the user's perspective, the angle at which the user extends hand H toward the opponent becomes obtuse, making it easier to pass hand H through gap 4, thereby lowering the difficulty of block practice in which hand H is extended toward the opponent. Therefore, the volleyball training tool 1 can adjust the difficulty of block practice by adjusting the installation height of guide line member 3 using height adjustment means 24. In this way, the volleyball training tool 1 can adjust the difficulty of block practice in which hand H is extended toward the opponent beyond the top of the volleyball net 9, and can correct the user's block form to a preferable block form.

[0042] Fig. 6 is a perspective view showing a volleyball training tool 1 according to another embodiment of the present invention. The support members 2, 2 of the volleyball training tool 1 shown in Fig. 6 are provided with a gap adjustment means 25 that adjusts the size of the gap 4 by changing the installation interval of the guide line members 3. The size here refers to the front-to-rear width between the guide line members 3 and one surface of the volleyball net 9. The gap adjustment means 25 is, for example, a plate member with a thickness of 2 cm.

[0043] 6(a), by providing the spacing adjustment means 25 between the support members 2, 2 and the guide line member 3, the installation height of the guide line member 3 remains unchanged but the installation spacing of the guide line member 3 changes, widening the front-to-back width of the gap 4. If multiple spacing adjustment means 25 are provided between the support members 2, 2 and the guide line member 3, the installation spacing changes by the number of spacing adjustment means 25 provided, and the front-to-back width of the gap 4 becomes wider.

[0044] When the installation interval is changed and the front-to-rear width of the gap 4 is widened, the user has more leeway in timing to extend his / her hand H toward the opponent, thereby making the block practice easier. Therefore, the volleyball training tool 1 can adjust the difficulty of block practice by adjusting the installation interval of the guide line members 3 using the interval adjustment means 25. In this way, the volleyball training tool 1 can adjust the difficulty of block practice, in which the user extends his / her hand H beyond the top edge of the volleyball net 9 toward the opponent, and can correct the user's block form to a desirable block form.

[0045] 6(b), the gap adjusting means 25 can be provided between the support members 2, 2 (contact surfaces 21, 21) and the upper end portion 90 to change the installation interval and increase the gap 4. The gap adjusting means 25 is preferably provided between the support members 2, 2 and the guide line member 3. The gap adjusting means 25 may be provided between the support members 2, 2 and the guide line member 3 and between the support members 2, 2 and the upper end portion 90, respectively.

[0046] Although urethane is preferable for the support members 2, 2 and the spacing adjustment means 25, any material can be used as long as it can withstand the contraction force of the guide line member 3, tension the guide line member 3, easily maintain its shape, and will not cause injury even if it is hit during practice.

[0047] Next, a second embodiment of the present invention will be described. Note that the description of the same parts as the first embodiment will be omitted, and the description will focus on the parts that are different from the first embodiment.

[0048] FIG. 7 is a perspective view showing a volleyball training tool 10 according to a second embodiment of the present invention. The volleyball training tool 10 shown in FIG. 7 includes support members 200. The support member 200 has a winding slot 210 and a fastening slot 220 formed integrally therewith. The winding slot 210 is provided on the outside side 203 of the support member 200, which is away from the volleyball net 9, and on the upper end side 204 of the support member 200, and opens from the opposing side 201 of the opposing support members 200 to the opposite side 202 of the support member 200 located opposite the opposing side 201. The fastening slot 220 is provided on the inside side 205 of the support member 200, which is close to the volleyball net 9, and on the lower end side 206 of the support member 200, and opens from the opposing side 201 to the opposite side 202.

[0049] As in the first embodiment, it is preferable to use urethane for the support member 200. However, the material is not limited to urethane as long as it can withstand the contraction force of the guide line member 3 while tensioning the guide line member 3, easily maintain its shape, and is flexible enough to prevent injury even if it is hit during practice.

[0050] The winding slot 210 separates a portion of the upper end of the support member 200 to form a winding portion 211. Both ends of the guide line member 3 are wound around the winding portions 211, 211 of the support member 200, respectively, and the guide line member 3 is tensioned parallel and horizontally to the volleyball net 9 between the support members 200, 200. The upper end portion 90 of the volleyball net 9 enters the fastening slot 220, allowing the support member 200 to be detachably fastened to the upper end portion 90.

[0051] 8 is a schematic diagram showing the support member 200 attached to the volleyball net 9 in FIG. 7. The support member 200 is attached to the outer upper end 90 of each side band 94 provided at both ends of the volleyball net 9 by a fastening slot 220. The support members 200 are attached outwardly of the antennas 95, which are also attached outwardly to the side bands 94. In this case, the support members 200 are attached in contact with the antennas 95, so that even if the support members 200 are pulled by the contractile force of the guide line member 3, the antennas 95 function as stoppers, allowing the support members 200 to be stably attached to the volleyball net 9.

[0052] Fig. 9 is a perspective view showing the support member 200 of the volleyball training tool 1 shown in Fig. 7. The fastening slot 220 is composed of a guide portion 221 with a tapered opening, a holding portion 223 that holds the portion of the upper end portion 90 through which the upper cable 92 of the volleyball net 9 passes, and a passage portion 222 that connects the guide portion 221 and the holding portion 223.

[0053] The guide portion 221 opens wider than the thickness of the upper end portion 90 in the front-to-rear direction and narrows toward the passage portion 222, so that the upper end portion 90 is guided into the path portion 222 when it enters the fastening slot.

[0054] The passage 222 guides the upper end portion 90 that has entered from the guide portion 221 to the holding portion 223 located further back. The distance between the passage portions 222 in the front-to-rear direction in the support member 200 is smaller than or equal to the thickness of the upper end portion 90 of the volleyball net 9 at the portion through which the upper cables 92 pass. Because the support member 200 is flexible, the passage portions 222 can allow the upper end portion 90 to pass through even if the distance between the passage portions 222 in the front-to-rear direction is smaller than the thickness of the upper end portion 90 of the volleyball net 9 at the portion through which the upper cables 92 pass. It is preferable that the passage portions 222 extend to the holding portion 223 at a regular interval.

[0055] The holding portions 223 have a greater distance in the front-to-rear direction than the passage portions 222, and can hold the upper end portions 90 of the portions of the volleyball net 9 through which the upper cables 92 pass. Therefore, the distance in the front-to-rear direction between the holding portions 223 may be equal to or greater than the thickness of the upper end portions 90 of the portions of the volleyball net 9 through which the upper cables 92 pass.

[0056] The upper end portion 90 is held by the holding portion 223 of the fastening slot 220, so that the support members 200, 200 are stably fastened to the upper end portion 90. Furthermore, because the support member 200 is flexible, it can be easily removed even when the upper end portion 90 is held by the holding portion 223 of the fastening slot 220. Therefore, the fastening slot 220 functions as the fastening means 20.

[0057] Furthermore, the bottom surface 212 of the winding slot 210 and the top surface 224 of the fixing slot 220 are at the same height. Therefore, when the support members 200, 200 are fixed to the upper end portions 90, respectively, and the guide line member 3 is wound around the winding portion 211 at the bottom surface 212 of the winding slot 210, the guide line member 3 is positioned at the same height as the upper end of the volleyball net 9.

[0058] The support member 200 only needs to be able to tension the guide line member 3 while withstanding the contraction force of the guide line member 3, and to form a gap 4 between the volleyball net 9 and the guide line member 3. Therefore, the winding slot 210 does not necessarily have to open from the opposite side 201 to the opposite side 202, but may open from the opposite side 201 to the outside side 203, or from the opposite side 202 to the outside side 203. The fastening slot 220 also does not necessarily have to open from the opposite side 201 to the opposite side 202, but may open from the opposite side 201 to the inside side 205, or from the opposite side 202 to the inside side 205.

[0059] Therefore, by integrally forming the winding slots 210 and the fastening slots 220 simply by forming the shape, the support member 200 can be detachably fastened to the upper end portion 90 using the fastening slots 220, and the guide line member 3 can be tensioned using the winding slots 210. Therefore, since the winding slots 210 and the fastening slots 220 of the support member 200 are integrally formed, the manufacturing cost of the volleyball training tool 10 can be reduced.

[0060] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described examples and can be embodied in various forms without departing from the spirit of the present invention. [Explanation of symbols]
