Description

[Technical field]

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

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

[0003] [Patent Document 1] Jitsuzen No. 57-103759 Summary of the Invention [Problem to be solved by the invention]

[0004] However, due to the nature of vaulting exercise, which involves jumping on a vaulting box, the impact of falling is great if you lose your balance on the vaulting box, and the above-mentioned mats are insufficient in terms of safety.

[0005] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a mat for a vaulting box that increases safety when performing vaulting box exercises. [Means for solving the problem]

[0006] The present invention provides a mat for a vaulting box, comprising a first mat portion that is 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 that are 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, the second mat portion is also located on the side of the vaulting box, making it possible to prevent injury when a person loses balance on the vaulting box and falls to the side. Furthermore, the second mat portion, located far from the landing point, is connected to the first mat portion, which prevents the second mat portion from floating up and prevents the contact area of ​​the entire vaulting box mat with the floor from decreasing, maintaining the frictional force between the entire vaulting box mat and the floor and preventing the vaulting box mat from shifting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A vaulting box mat 1 according to an embodiment of the present invention will now be described with reference to FIGS.

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

[0012] The first mat section 2 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 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 of this embodiment, the second mat portion 3 is also arranged on the side of the vaulting box A, making 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 is independent of apparent area," which means that "frictional force is proportional to the actual contact area, not the apparent area."

[0016] Here, if the first mat part 2 is placed only on the landing surface as in the conventional vaulting box exercise, when landing, the first mat part 2 will be in a shape that lifts up the parts 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 part of the mat at that position will not lift up, and the decrease in the frictional force of the mat as a whole will be suppressed.

[0018] Therefore, in this embodiment, taking into consideration that the second mat section 3 placed on the side of the vaulting box A is placed at a position 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 a reduction in the contact area of ​​the entire vaulting box mat 1 with the floor, thereby 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 is 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 specified ratio, and a lower compression hardness means that the mat is soft.

[0021] That is, the second mat section 3 is constructed to be soft in order to reduce the impact of the sideways fall 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 not be stable. Therefore, the first mat section 2 is constructed to be at least harder than the second mat section 3.

[0022] For example, it is conceivable that the first mat portion 2 is made of a material similar to that of a normal gymnastics mat, and the second mat portion 3 is made of a material similar to that of an Evermat.

[0023] 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 anything other than the feet, making it possible to further prevent 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.

[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 part 2 and the pair of second mat parts 3 each have an approximately rectangular shape, and the pair of second mat parts 3 are each attachable and detachable to the first mat part 2, so that the vaulting box mat 1 has an approximately rectangular shape overall when the first mat part 2 and the pair of second mat parts 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 is attachable and detachable to the side 21 side of the first mat part 2.

[0027] In this manner, when assembled to form a generally rectangular shape overall, vaulting box mat 1 can be used as a large mat for purposes other than vaulting box exercise.

[0028] To use the vaulting box mat 1 as a large mat, it is preferable that the first mat part 2 and the second mat part 3 have approximately the same thickness, but if the second mat part 3 is constructed to be soft in order 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 part 3, and then make the thickness of the first mat part 2 approximately the same.

[0029] As the above-mentioned detachable configuration, for example, a hook-and-loop fastener or the like may be provided 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 to make them detachable, or a hook-and-loop fastener or the like may be used to make them detachable via a connecting member extending from the first mat portion 2 (or the pair of second mat portions 3) to the pair of second mat portions 3. In this embodiment, a connecting member such as a hook-and-loop fastener is provided on the entire one side 21 of the first mat portion 2 and the entire one side 31 of each second mat portion 3, respectively, making it possible to freely change the connection position.

[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 disconnected (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 substantially in contact with the side surface of the vaulting box A (S3). Note that the order of steps S2 and S3 may be reversed.

[0032] Finally, the first mat portion 2 and the pair of second mat portions 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 part 2 and the pair of second mat parts 3 are detachable from each other, 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 without any gaps to the side of the vaulting box A by adjusting the connection position of the second mat part 3 to the first mat part 2. Furthermore, by releasing the connection, it becomes possible to use each part individually and also makes transportation and storage easy.

[0034] Furthermore, because the second mat part 3 is detachable, it is easy for the second mat part 3 to bend relative to the first mat part 2 when in the attachment / detachment position, so that the second mat part 3 is less susceptible to the effects of the first mat part 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 to enable the above connection.

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

[0037] For example, the length of the other side 32 of the second mat section 3 may be set to correspond to each of small, medium and large sized vaulting boxes A (for example, if used for a small vaulting box A, the length of the other side 32 may be approximately 80 cm), or the length of the other side 32 may be set to match a large vaulting box A so as to be compatible with small, medium and large sized boxes A. Also, the length of the other side 32 of the second mat section 3 may be set so that it extends forward beyond the front end of the vaulting box A (the end on the takeoff side).

[0038] Furthermore, in this embodiment, the first mat member 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 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, 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 folding 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 part 25 and the second connecting part 26 are located away from the normal landing range B (FIG. 5(a)), preventing the athlete from landing on the first connecting part 25 and the second connecting part 26 and losing balance.

[0047] Furthermore, in this embodiment, the back surface of the large mat portion 22 is provided with an anti-slip coating. surface The front and back surfaces of the small mat portions 23 and 24 are not provided with an anti-slip material. As an anti-slip material, a piece of fabric made of an anti-slip material may be attached to the back surface of the large mat portion 22, or the like.

[0048] As a result, when the vaulting box mat 1 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 portion 2 is folded, it is possible to provide a surface D that does not have the anti-slip coating C, as shown in Figure 6(a) or Figure 6(b), so that it can also be used as a smaller mat.

[0049] In addition, when the first mat part 2 is folded so that the anti-slip C contacts the ground as shown in Fig. 6(a), a gap is generated between the first small mat part 23 and the second small mat part 24, and it may be unsuitable for use as a small mat. In that case, as shown in Fig. 6(b), it is possible to fold it so that the anti-slip C is located on the inside and arrange the first small mat part 23 and the second small mat part 24 so that they contact the ground, and use it as a small mat with no gap between the first small mat part 23 and the second small mat part 24. In this case, the anti-slip C does not contact the ground, but since it is a small mat that is unsuitable for the landing surface of a vaulting box, this is not a big problem.

[0050] As described above, the vaulting box mat 1 in this embodiment comprises a first mat section 2 arranged on the landing surface of the vaulting box A where jumping takes place in a first direction X, and a pair of second mat sections 3 arranged on either side of the vaulting box A, with the first mat section 2 and the pair of second mat sections 3 being connected to each other.

[0051] With this configuration, the second mat portion 3 is also disposed on the side of the vaulting box A, making it possible to prevent injury when a person loses balance on the vaulting box A and falls to the side. Furthermore, the second mat portion 3, which is disposed at a position far from the landing point, is connected to the first mat portion 2, which prevents the second mat portion 3 from floating up and prevents a reduction in the contact area of ​​the entire vaulting box mat 1 with the floor, thereby maintaining the frictional force between the entire vaulting box mat 1 and the floor and preventing the vaulting box mat 1 from shifting.

[0052] Moreover, in the vaulting box mat 1 according to this embodiment, the pair of second mat parts 3 are attachable to and 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 place the second mat part 3 on the side of the vaulting box A without any gaps by adjusting the connection position of the second mat part 3 to the first mat part 2. Also, by disconnecting the connection, it becomes possible to use each part individually and also makes transportation and storage easier. Furthermore, since the second mat part 3 is detachable, it is easy for the second mat part 3 to bend relative to the first mat part 2 in the attachment and detachment position, so the second mat part 3 is less susceptible to the influence of the first mat part 2 lifting up when landing, and the entire vaulting box mat 1 is further prevented from shifting.

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

[0055] According to such a configuration, the mats can be assembled to have a substantially rectangular shape overall, so that the vaulting box mat 1 can be used as a large mat for purposes other than vaulting box exercise.

[0056] In addition, in the vaulting box mat 1 of 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 and the surfaces of each small mat portion 23, 24 face each other and abut.

[0057] With this configuration, the vaulting box mat 1 can be folded neatly, and the folded vaulting box mat 1 can be used as a mat with twice the thickness and half the usable surface area. Furthermore, when using the vaulting box mat 1 for vaulting, the first connecting part 25 and the second connecting part 26 are located away from the normal landing range B, so that the athlete is prevented from landing on the first connecting part 25 and the second connecting part 26 and losing balance.

[0058] In addition, in the vaulting box mat 1 according to the present embodiment, the back surface of the large mat portion 22 is provided with a non-slip surface. surface Furthermore, the front and back surfaces of each of the small mat portions 23 and 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 portion 2 is folded, a surface that is not anti-slip can be provided, so it can also be used as a smaller mat.

[0060] Moreover, in the vaulting box mat 1 according to this embodiment, the pair of second mat parts 3 are configured to have a lower compression hardness than the first mat part 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 anything 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 part 3 is detachably attached to one side 21 of the first mat part 2, but as shown in Fig. 7, the other side 32 of the second mat part 3 may also be configured to be detachably attached to one side 21 of the first mat part 2. In this case, by making the lengths of the one side 21 and the other side 32 different, it is possible to accommodate changes in the length of the vaulting box A and changes in the orientation of the vaulting box (e.g., from horizontal to vertical).

[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 is adjustable.

[0065] However, when the side surfaces of the first mat part 2 and the second mat part 3 are directly connected to each other, a small gap may be created at the connection, which may cause a foot to get caught. 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 considered 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 along the gap, respectively, to enable connection.

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

[0068] However, in this case, if the first mat part 2 is used alone, the gap cover E will be in a state of protruding from the end of the first mat part 2, which may cause a danger such as a player stepping on it. Therefore, the gap cover E may be configured to be detachable to the side surface 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 surface 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 surface 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 be applied to the gap between the first small mat portion 23 and the second small mat portion 24 shown in Fig. 6(b). In detail, a gap cover E is further provided that can connect the upper surface of the open third side 23a side of the first small mat portion 23 and the upper surface of the open third side 24a side of the second small mat portion 24. 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 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 portion are directly connected to each other, but it is also possible to realize a configuration in which "a pair of second mat portions 3 are each detachable from the first mat portion 2" by using the gap cover E.

[0071] In addition, 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]
