Vaulting box mat

Abstract

To provide a vaulting box mat that enhances safety during vaulting box exercises.SOLUTION: A vaulting box mat 1 includes a first mat section 2, which is placed on a landing surface of a vaulting box A where jumping occurs in a first direction X, and a pair of second mat sections 3, which are arranged on both sides of the vaulting box A. The first mat section 2 and the pair of second mat sections 3 are each connected. Since the second mat sections 3 are arranged on the sides of the vaulting box A, it is possible to suppress injuries in the event that a user loses balance on the vaulting box A and falls to the side. Furthermore, since the second mat sections 3, which are arranged at positions far from a landing point, are connected to the first mat section 2, the lifting of the second mat sections 3 is suppressed. As a result, reduction in the contact area between the whole vaulting box mat 1 and a floor is suppressed, thereby maintaining friction between the whole vaulting box mat 1 and the floor, and preventing the vaulting box mat 1 from slipping.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a mat for a vaulting box that enhances safety during vaulting box exercises. [Background technology]

[0002] Conventionally, vaulting box exercises are performed with a mat placed behind the vaulting box, that is, on the landing surface, to ensure stability and prevent injury when landing (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Jitsuzen Showa 57-103759 Summary of the Invention [Problem to be solved by the invention]

[0004] However, due to the nature of vaulting box exercises, in which the athlete jumps on a vaulting box, the impact of falling when the athlete loses balance on the box is great, and the mats described above are insufficient in terms of safety.

[0005] Therefore, an object of the present invention is to provide a mat for a vaulting box that increases safety during vaulting box exercises. [Means for solving the problem]

[0006] The present invention provides a mat for a vaulting box, comprising a first mat portion placed on the landing surface of the vaulting box where the jump is made in a first direction, and a pair of second mat portions placed on either side of the vaulting box, the first mat portion and the pair of second mat portions being connected to each other.

[0007] With this configuration, second mat sections are also placed on the sides of the vaulting box, making it possible to prevent injury if a person loses balance on the vaulting box and falls to the side. Furthermore, because the second mat section, which is placed farther from the landing point, is connected to the first mat section, the second mat section is prevented from floating up, preventing a decrease in the contact area of ​​the entire vaulting box mat with the floor. This maintains the frictional force between the entire vaulting box mat and the floor, preventing the vaulting box mat from slipping. [Effects of the Invention]

[0008] According to the vaulting box mat of the present invention, it is possible to increase safety during vaulting box exercises. [Brief explanation of the drawings]

[0010] A vaulting box mat 1 according to an embodiment of the present invention will now be described with reference to FIGS. 1 to 6. FIG.

[0011] The vaulting box mat 1 is used for vaulting box exercise, and as shown in FIG. 1, comprises a first mat portion 2 and a pair of second mat portions 3.

[0012] The first mat section 2 is placed on the landing surface of the vaulting box A where jumping is performed in the first direction X, and a pair of second mat sections 3 are placed on both sides of the vaulting box A, and the first mat section 2 and the pair of second mat sections 3 are connected to each other.

[0013] In this way, in the vaulting box mat 1 according to this embodiment, the second mat portion 3 is also arranged on the side of the vaulting box A, which makes it possible to prevent injury when a person loses balance on the vaulting box A and falls to the side.

[0014] Furthermore, the first mat portion 2 and the pair of second mat portions 3 are connected to each other, which also contributes to preventing the vaulting box mat 1 from shifting when landing.

[0015] Coulomb's law of friction states that "frictional force does not depend on apparent area," which means that "frictional force is proportional to the actual contact area, not the apparent area."

[0016] If the first mat part 2 is placed only on the landing surface, as in the conventional vaulting box exercise, when the person lands, the first mat part 2 will be raised in the areas other than the landing point as shown in Figure 2, and the contact area between the first mat part 2 and the floor will be greatly reduced except for the landing point. As a result, the friction force between the first mat part 2 and the floor will be small, and the first mat part 2 will easily slip off.

[0017] However, since the lifting force is less transmitted the farther away from the landing point, if the mat extends to a position far away from the landing point, the mat part at the far away position will not lift up, and the frictional force of the entire mat will not decrease.

[0018] Therefore, in this embodiment, taking into consideration that the second mat section 3 placed on the side of the vaulting box A is positioned far from the landing point to prevent injury, a pair of second mat sections 3 are each connected to the first mat section 2.

[0019] This prevents the second mat portion 3 from floating up, thereby preventing the contact area of ​​the entire vaulting box mat 1 with the floor from decreasing, maintaining the frictional force between the entire vaulting box mat 1 and the floor and preventing the vaulting box mat 1 from slipping.

[0020] Returning to Fig. 1, the pair of second mat parts 3 are configured to have a lower compression hardness than the first mat part 2. Compression hardness is the pressure required to compress a mat or the like by a predetermined ratio, and a lower compression hardness means that the mat is softer.

[0021] In other words, the second mat section 3 is constructed to be soft in order to reduce the impact of the fall to the side of the vaulting box A. On the other hand, the first mat section 2 is where the person lands, so if it is too soft, the landing will be unstable. Therefore, the first mat section 2 is constructed to be at least harder than the second mat section 3.

[0022] For example, the first mat portion 2 may be made of the same material as a normal gymnastics mat, and the second mat portion 3 may be made of the same material as an Evermat.

[0023] With this configuration, the soft second mat part 3 is placed on the side of the vaulting box A, where there is a high possibility of falling on something other than the feet, making it possible to further reduce injury when losing balance on the vaulting box A and falling to the side, while the first mat part 2, which is suitable for landing, is placed on the landing surface, ensuring a stable landing.

[0024] Next, a method for installing the vaulting box mat 1 on the vaulting box A will be described.

[0025] In this embodiment, the first mat section 2 and the pair of second mat sections 3 each have an approximately rectangular shape, and the pair of second mat sections 3 are each detachable from the first mat section 2, so that the vaulting box mat 1 has an approximately rectangular shape overall when the first mat section 2 and the pair of second mat sections 3 are combined, as shown in Figure 3.

[0026] In detail, the length of one side 21 of the first mat part 2 is approximately the same as the sum of the lengths of one side 31 of each second mat part 3, and the side 31 side of each second mat part 3 can be attached and detached to the side 21 side of the first mat part 2.

[0027] In this state where the mats are assembled to form a generally rectangular shape overall, the vaulting box mat 1 can be used as a large mat for purposes other than vaulting box exercises.

[0028] To use the vaulting box mat 1 as a large mat, it is preferable that the first mat portion 2 and the second mat portion 3 have approximately the same thickness, but if the second mat portion 3 is constructed to be soft to prevent injury in the event of a fall, a certain degree of thickness is required. Therefore, it is preferable to first set the thickness of the second mat portion 3, and then make the thickness of the first mat portion 2 approximately the same.

[0029] The detachable configuration may be, for example, by providing hook-and-loop fasteners or the like on the side surface of one side 21 of the first mat portion 2 and the side surface of one side 31 of each second mat portion 3, or by using a connecting member extending from the first mat portion 2 (or a pair of second mat portions 3) to the pair of second mat portions 3 to enable attachment and detachment with hook-and-loop fasteners or the like. In this embodiment, a connecting member such as hook-and-loop fasteners is provided on the entire side of one side 21 of the first mat portion 2 and on the entire side of one side 31 of each second mat portion 3, so that the connection position can be freely changed.

[0030] When installing the vaulting box mat 1 on the vaulting box A, as shown in Figure 4, first, the connection between the first mat part 2 and the pair of second mat parts 3 is released (S1), and the first mat part 2 is positioned so that one side 21 is approximately in contact with the rear end (the end on the landing side) of the vaulting box A (S2).

[0031] Next, the pair of second mat parts 3 are arranged so that the other sides 32 of the second mat parts 3 are in approximate contact with the side surfaces of the vaulting box A (S3). Note that the order of steps S2 and S3 may be reversed.

[0032] Finally, the first mat section 2 and the pair of second mat sections 3 are reconnected, thereby completing the installation of the vaulting box mat 1 on the vaulting box A (S4).

[0033] In this way, because the first mat section 2 and the pair of second mat sections 3 are detachable, even if the width of the vaulting box A is changed due to a change in the number of steps, etc., it is possible to position the second mat section 3 without any gaps to the side of the vaulting box A by adjusting the connection position of the second mat section 3 to the first mat section 2. Furthermore, by releasing the connection, each section can be used separately, and transportation and storage are also easy.

[0034] Furthermore, because the mat is detachable, the second mat portion 3 can easily bend relative to the first mat portion 2 when in the detachable position, making the second mat portion 3 less susceptible to the effects of the first mat portion 2 floating up when landing, further preventing the entire vaulting box mat 1 from shifting.

[0035] Naturally, one side 21 of the first mat portion 2 needs to be longer than the width of the vaulting box A in order to enable the above connection.

[0036] Furthermore, the Ministry of Education, Culture, Sports, Science and Technology standards stipulate that the length of a vaulting box is 80 cm for small (elementary school students), 100 cm for medium (elementary school students to junior high school students), and 120 cm for large (junior high school students and above), but the length of the other side 32 of the second mat section 3 can be set according to the length of the vaulting box A that uses the vaulting box mat 1.

[0037] For example, it is possible to prepare mats in which the length of the other side 32 of the second mat section 3 is set to correspond to each of small, medium and large sized vaulting boxes A (for example, if used with a small vaulting box A, the length of the other side 32 is approximately 80 cm), or it is also possible to use mats in which the length of the other side 32 is set to match the large vaulting box A so that it can be used for small, medium and large sized vaulting boxes A. It is also possible to use mats in which the length of the other side 32 is set so that the second mat section 3 extends further forward than the front end of the vaulting box A (the end on the takeoff side).

[0038] Furthermore, in this embodiment, the first mat portion 2 is configured to be foldable.

[0039] In detail, as shown in Figure 5, the first mat portion 2 comprises a large mat portion 22, a first small mat portion 23, a second small mat portion 24, a first connecting portion 25, and a second connecting portion 26.

[0040] The large mat portion 22, the first small mat portion 23, and the second small mat portion 24 each have a substantially rectangular shape.

[0041] A pair of opposing first sides 22a of the large mat portion 22 each have a first length, and another pair of opposing second sides 22b each have a second length.

[0042] The first small mat portion 23 and the second small mat portion 24 have the same size, and the pair of opposing third sides 23a, 24a of each small mat portion 23, 24 each have the above-mentioned first length, and the other pair of opposing fourth sides 23b, 24b each have a length that is half the above-mentioned second length.

[0043] One of the pair of third sides 23a of the first small mat portion 23 is connected to one of the pair of first sides 22a of the large mat portion 22 via a first connecting portion 25, and one of the pair of third sides 24a of the second small mat portion 24 is connected to the other of the pair of first sides 22a of the large mat portion 22 via a second connecting portion 26.

[0044] The first mat portion 2 can be folded at the first connecting portion 25 and the second connecting portion 26 so that the surface of the large mat portion 22 and the surfaces of the small mat portions 23 and 24 face each other and come into contact with each other.

[0045] Figure 5(b) illustrates an example of a configuration in which the surface of the large mat portion 22 and the surface of the second small mat portion 24 of the first small mat portion 23 are connected by a strip-shaped first connecting portion 25 and a second connecting portion 26, respectively, and the first mat portion 2 can be folded by bending these strip-shaped first connecting portion 25 and second connecting portion 26.

[0046] This allows the vaulting box mat 1 to be folded neatly, and the folded vaulting box mat 1 can be used as a mat that is twice as thick and has half the usable surface area. Furthermore, when using the vaulting box mat 1 for vaulting, the first connecting portion 25 and the second connecting portion 26 are positioned away from the normal landing range B (FIG. 5(a)), which prevents the athlete from landing on the first connecting portion 25 and the second connecting portion 26 and losing their balance.

[0047] Furthermore, in this embodiment, the back surface of the large mat portion 22 is provided with an anti-slip coating, but the back surface of the large mat portion 22 and the front and back surfaces of each of the small mat portions 23 and 24 are not provided with an anti-slip coating. One possible anti-slip coating is to attach a non-slip fabric to the back surface of the large mat portion 22.

[0048] This makes it possible to prevent the vaulting box mat 1 from slipping when landing when used for a vaulting box, and when the first mat portion 2 is folded, a surface D without anti-slip coating C can be provided, as shown in Figure 6(a) or 6(b), so that it can also be used as a smaller mat.

[0049] In addition, when the first mat portion 2 is folded so that the non-slip surface C contacts the ground, as shown in Figure 6(a), a gap is created between the first small mat portion 23 and the second small mat portion 24, making it unsuitable for use as a small mat. In that case, as shown in Figure 6(b), by folding the first mat portion 22 so that the non-slip surface C is located on the inside and arranging the first small mat portion 23 and the second small mat portion 24 so that they contact the ground, it is possible to use the mat as a small mat with no gap between the first small mat portion 23 and the second small mat portion 24. In this case, the non-slip surface C does not contact the ground, but this is not a major problem because the mat is small and unsuitable for use as a landing surface for a vaulting horse, etc.

[0050] As described above, the vaulting box mat 1 in this embodiment comprises a first mat section 2 that is placed on the landing surface of the vaulting box A where the jump is made in the first direction X, and a pair of second mat sections 3 that are placed on both sides of the vaulting box A, and the first mat section 2 and the pair of second mat sections 3 are each connected to each other.

[0051] With this configuration, the second mat portion 3 is also placed on the side of the vaulting box A, making it possible to prevent injury if a person loses balance on the vaulting box A and falls to the side. Furthermore, because the second mat portion 3, which is placed far from the landing point, is connected to the first mat portion 2, the second mat portion 3 is prevented from floating up, and the contact area of ​​the entire vaulting box mat 1 with the floor is prevented from decreasing, maintaining the frictional force between the entire vaulting box mat 1 and the floor and preventing the vaulting box mat 1 from slipping.

[0052] Furthermore, in the vaulting box mat 1 according to this embodiment, the pair of second mat parts 3 are detachable from the first mat part 2, respectively.

[0053] With this configuration, even if the width of the vaulting box A is changed due to a change in the number of steps, etc., it is possible to position the second mat part 3 next to the first mat part 2 without any gaps by adjusting the connection position of the second mat part 3 relative to the first mat part 2. Furthermore, by disconnecting the connection, each part can be used separately, and transportation and storage are also easy. Furthermore, because the second mat part 3 is detachable, it easily bends relative to the first mat part 2 in the detached position. This makes the second mat part 3 less susceptible to the lift-up of the first mat part 2 when landing, further preventing the entire vaulting box mat 1 from shifting.

[0054] In addition, in the vaulting box mat 1 of this embodiment, the first mat portion 2 and the pair of second mat portions 3 each have an approximately rectangular shape, one side 21 of the first mat portion 2 is approximately the same length as the sum of one side 31 of each second mat portion 3, and one side 21 side of each second mat portion 3 is attachable and detachable to one side 21 side of the first mat portion 2.

[0055] According to this configuration, the mats can be combined to form a substantially rectangular shape as a whole, so that the vaulting box mat 1 can be used as a large mat for purposes other than vaulting box exercises.

[0056] In addition, in the vaulting box mat 1 according to this embodiment, the first mat portion 2 can be folded at the first connecting portion 25 and the second connecting portion 26 so that the surface of the large mat portion 22 faces and abuts against the surfaces of each of the small mat portions 23 and 24.

[0057] With this configuration, the vaulting box mat 1 can be neatly folded, and the folded vaulting box mat 1 can be used as a mat that is twice as thick and has half the usable surface area. Furthermore, when using the vaulting box mat 1 for vaulting, the first connecting portion 25 and the second connecting portion 26 are positioned away from the normal landing range B, which prevents the athlete from landing on the first connecting portion 25 and the second connecting portion 26 and losing their balance.

[0058] In addition, in the vaulting box mat 1 according to this embodiment, the back surface of the large mat portion 22 is provided with an anti-slip coating, while the back surface of the large mat portion 22 and the front and back surfaces of each small mat portion 23, 24 are not provided with an anti-slip coating.

[0059] With this configuration, when the vaulting box mat is used for a vaulting box, it is possible to prevent the vaulting box mat 1 from slipping when landing, and when the first mat part 2 is folded, it is possible to provide a surface that is not slip-resistant, so it can also be used as a smaller mat.

[0060] Furthermore, in the vaulting box mat 1 according to this embodiment, the pair of second mat portions 3 are configured to have a lower compression hardness than the first mat portion 2.

[0061] With this configuration, the soft second mat portion 3 is placed on the side of the vaulting box A, where there is a high possibility of falling on something other than the feet, making it possible to further reduce injury when losing balance on the vaulting box A and falling to the side, while the first mat portion 2, which is suitable for landing, is placed on the landing surface, ensuring a stable landing.

[0062] The vaulting box mat of the present invention is not limited to the above-described embodiment, and various modifications and improvements are possible within the scope of the claims.

[0063] For example, in the above embodiment, one side 31 of each second mat section 3 was detachably attached to one side 21 of the first mat section 2, but as shown in Figure 7, the other side 32 of the second mat section 3 may also be configured to be detachably attached to one side 21 of the first mat section 2. In this case, by making the lengths of the one side 21 and the other side 32 different, it becomes possible to accommodate changes in the length of the vaulting box A and changes in the orientation of the vaulting box (from horizontal to vertical, etc.).

[0064] In addition, in the above embodiment, connecting members such as hook-and-loop fasteners were provided on the entire side surface of one side 21 of the first mat portion 2 and on the entire side surface of one side 31 of each second mat portion 3, but they may be provided partially as long as the connection position of the second mat portion 3 relative to the first mat portion 2 can be adjusted.

[0065] However, when the sides of the first mat part 2 and the second mat part 3 are directly connected to each other, a small gap may be formed at the connection, which may cause a foot to get caught in. Therefore, as shown in Fig. 8, when connecting the first mat part 2 and the second mat part 3, a gap cover E may be provided that can be connected to the top surface of one side 21 of the first mat part 2 and the top surface of one side 31 of each second mat part 3 to cover the gap.

[0066] For example, as shown in Figure 8, a configuration is possible in which hook-and-loop fasteners or buttons are provided on the upper surface of one side 21 of the first mat portion 2, the upper surface of one side 31 of each second mat portion 3, and the bottom surface of the gap cover E extending in a strip shape along the gap, so that they can be connected.

[0067] In addition, as shown in Figure 8(b), the gap cover E may be non-detachably connected to either the upper surface of one side 21 of the first mat part 2 or the upper surface of one side 31 of each second mat part 3 (in Figure 8(b), it is non-detachably connected to the upper surface of one side 21 of the first mat part 2).

[0068] However, in this case, if the first mat part 2 is used alone, the gap cover E will protrude from the end of the first mat part 2, which may pose a risk of being stepped on by a player. Therefore, the gap cover E may be configured to be detachable to the side of the first mat part 2 or the second mat part 3 to which the gap cover E is undetachably connected. For example, as shown in FIG. 8(c), a hook-and-loop fastener may be provided on the side of the first mat part 2 or the second mat part 3 to which the gap cover E is undetachably connected, so that the protruding part of the gap cover E can be connected to the side of the first mat part 2 or the second mat part 3 to which the gap cover E is undetachably connected.

[0069] A similar configuration can also be applied to the gap between the first small mat portion 23 and the second small mat portion 24 shown in Figure 6(b). In detail, a gap cover E is further provided that can connect the upper surface of the first small mat portion 23 on the open third side 23a side and the upper surface of the second small mat portion 24 on the open third side 24a side. The gap cover E is non-detachably connected to the upper surface of the first small mat portion 23 or the upper surface of the second small mat portion 24, and may also be configured to be detachably attached to the side surface of the first small mat portion 23 or the second small mat portion 24 to which the gap cover E is non-detachably connected.

[0070] Furthermore, in the above embodiment, a configuration has been described in which the sides of each mat section are directly connected to each other, but the gap cover E may also be used to realize a configuration in which "a pair of second mat sections 3 are each detachable from the first mat section 2."

[0071] Furthermore, in the above embodiment, the pair of second mat parts 3 are configured to have a lower compression hardness than the first mat part 2, but it goes without saying that they may have the same compression hardness. [Explanation of symbols]
