Description

[Technical field]

[0001] The present invention relates to a jumping apparatus and a safety net. More specifically, the present invention relates to a jumping apparatus equipped with a safety net for preventing a user from falling, and a safety net to be attached to the jumping apparatus. [Background technology]

[0002] Trampolines (registered trademark), or jumping equipment, are becoming increasingly popular as an exercise device that anyone, from adults to children, can play with and exercise, and that has the following various effects:

[0003] (1) High movement efficiency Jumping exercise using a jumping machine is more efficient than jogging, and the amount of exercise done by jumping for 5 minutes is equivalent to the amount of exercise done by jogging 1km. (2) Improve lymphatic flow Jumping can increase lymphatic flow, which helps flush out waste products and allows the body to absorb nutrients more easily. (3) Strengthen muscles, core and brain When you jump and land, you use your inner muscles to maintain balance and keep yourself straight, so it helps train your muscles and core. Jumping exercises have the effect of promoting brain development, and by stimulating brain activity, they have the effect of improving memory, concentration, and comprehension. (4) Prevention of osteoporosis Bouncing up and down helps stop bone loss, stabilizes bone density, and prevents falls.

[0004] In this context, various jumping equipment have been proposed. For example, Patent Document 1 discloses a jumping equipment shown in FIG. That is, the jumping apparatus 200 described in Patent Document 1 comprises an inner net 201 that is stretched horizontally to enable repetitive jumping exercise, an outer net 202 that is stretched horizontally continuous with the outer edge of the inner net 201 to prevent a user from falling off the inner net 201 during repetitive jumping exercise, and a number of leaf springs 203 arranged approximately vertically to elastically support the inner net 201 and the outer net 202 from below.

[0005] Each leaf spring 203 has a first leaf spring 203A whose upper end is connected to the outer peripheral edge of the external mesh 202, a second leaf spring 203B whose upper end is connected to the connecting portion of the internal mesh 201 and the external mesh 202, and a connecting portion 203C that connects the lower portion of the first leaf spring 203A to the lower portion of the second leaf spring 203B. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2002-210035 A Summary of the Invention [Problem to be solved by the invention]

[0007] Since a jumping apparatus is a device for enabling a user to perform repetitive up and down jumping exercises, the support part that supports the jumping surface of the jumping apparatus has a certain height, and even in the jumping apparatus 200 described in Patent Document 1, the height of the leaf spring 203 is 1.5 m. Therefore, since there is a possibility that a user may lose balance during jumping exercise and fall off the jumping apparatus, measures are taken to prevent falls.

[0008] Patent Document 1 describes that in a jumping apparatus 200, an outer net 202 is arranged around the outer periphery of an inner net 201, so that even if a user falls off the inner net 201, he or she can land safely on the outer net 202 and will not fall off the jumping apparatus 200.

[0009] However, since a user can perform repetitive jumping exercises over almost the entire upper surface of the jumping apparatus 200 of Patent Document 1, there is a possibility that the user may fall off the external net 202 and fall from the jumping apparatus 200, and therefore it was necessary to attach a safety net to the jumping apparatus 200 to prevent falls.

[0010] In order to install the safety net, each post had to be fixed in place using screws, etc., which took a lot of time. As a result, the jumping equipment was used without the safety net installed, and there were cases where users fell off the equipment and were injured. In particular, the jumping equipment 200 of Patent Document 1 does not have a frame portion that is provided in general jumping equipment, and the inner net 201 and outer net 202 are supported by leaf springs 203, making it very difficult to attach the safety net posts.

[0011] Therefore, there has been a demand for a jumping device that allows the safety net to be easily attached and removed.

[0012] The present invention has been devised in consideration of the above points, and aims to provide a jumping apparatus to which a safety net can be easily attached and detached, and a safety net that can be easily attached and detached to existing jumping apparatus. [Means for solving the problem]

[0013] In order to achieve the above-mentioned object, the jumping apparatus of the present invention comprises a frame portion surrounding a predetermined range, an elastic stretchable portion attached to the frame portion while being surrounded by the frame portion, legs extending in the longitudinal direction and connected to the lower part of the frame portion approximately perpendicular to the frame portion, a support portion having a mesh portion attached thereto and extending in the longitudinal direction, and a support receiving portion extending in the longitudinal direction, having an insertion hole formed therethrough in the longitudinal direction, capable of releasably fixing the support portion inserted into the insertion hole, and provided outside the frame portion with the longitudinal direction approximately the same as the vertical direction.

[0014] Here, an insertion hole is formed that extends in the longitudinal direction and penetrates in the longitudinal direction, and the support part inserted into the insertion hole can be releasably fixed. With the longitudinal direction approximately in the same direction as the vertical direction, the support part can be releasably fixed by pressing the support part inserted into the insertion hole of the support receiver against the inner wall of the support receiver, etc., using the support receiver provided outside the frame part. Therefore, the support part can be fixed and detached more easily than when the support part is directly fixed to the leg part.

[0015] In addition, when the post with the mesh portion attached, i.e., the post of the safety net, is inserted into the insertion hole through the opening at the upper end, the length of the mesh portion can be adjusted by making the post protrude or not protrude from the opening at the lower end opposite the opening at the upper end, which allows a greater degree of adjustment of the length of the mesh portion compared to a post receiving part that is not through and has a bottom. Furthermore, since the post receiving portion is provided on the outside of the frame portion, the post portions of the safety net can be easily inserted into the insertion holes of the post receiving portion without being hindered by the components of the jumping apparatus of the present invention.

[0016] In the jumping apparatus of the present invention, the post receiving portion can be configured so that the upper end of the post receiving portion is at approximately the same height as the upper surface of the frame portion.

[0017] In this case, the position of the post receiving portion is closer to the point on the safety net where the load is applied than when the upper end of the post receiving portion is at a lower height than the top surface of the frame portion, making it easier for the post receiving portion to support a safety net under load and easier for the safety net to withstand large loads. Furthermore, if the upper end of the pillar receiver is at a higher height than the upper surface of the frame, the center of gravity of the jumping equipment of the present invention will be higher, making the jumping equipment of the present invention more likely to shake, and when a user is using the jumping equipment of the present invention, the user's body may hit the pillar receiver directly, resulting in damage to the pillar receiver. However, if the upper end of the pillar receiver is at approximately the same height as the upper surface of the frame, the center of gravity will not be higher and the equipment will be less likely to shake, and the user's body will not hit the pillar receiver directly, preventing damage to the pillar receiver.

[0018] In the jumping apparatus of the present invention, the post receiving portion may be attached to the outer portion of the leg so as to extend in substantially the same direction as the longitudinal direction of the leg.

[0019] In this case, since more attachment points can be provided than when the support is attached to the outer portion of the frame, the support column receiving portion can be attached more firmly.

[0020] In the jumping apparatus of the present invention, the support column receiver can be configured to be detachably attached to the leg.

[0021] In this case, the post receiving parts are attached only to the legs to which the safety net is to be attached, making it possible to realize a variety of arrangements for the safety net while making full use of the post receiving parts.

[0022] In addition, in the jumping apparatus of the present invention, the length of the support column receiving portion can be configured to be at least 1 / 3 of the length from the upper surface of the frame portion to the ground surface of the leg portion.

[0023] The support pole of the safety net is inserted into the insertion hole from the opening at the upper end of the support pole receiving part, and then inserted into the support pole receiving part so that the support pole protrudes from the opening at the lower end opposite the opening at the upper end.Since the support pole receiving part has this length, the contact area between the support pole and the support pole receiving part is increased, and even if a large load is applied to the safety net, it is less likely that partial load will be applied to the support pole of the safety net, making it easier to withstand the large load.

[0024] In addition, in the jumping apparatus of the present invention, a fixing hole communicating with the insertion hole is formed in the support post receiving portion, and the support post receiving portion can be configured to have a fixing device that can be inserted removably into the fixing hole.

[0025] In this case, the safety net can be fixed or released simply by inserting the fastener into or removing it from the fixing hole of the support post receiving portion.

[0026] In the jumping apparatus of the present invention, the fixing hole of the post receiving portion can be configured to communicate with the insertion hole in a direction substantially perpendicular to the direction toward the frame portion.

[0027] In this case, even when the fixing device is inserted into the fixing hole in the support post receiving portion, the distance between the fixing device and the frame portion is approximately the same as the distance between the support post receiving portion and the frame portion, thereby preventing the jumping apparatus of the present invention from protruding outward.

[0028] In addition, in order to achieve the above-mentioned object, the safety net of the present invention comprises a support post portion to which a mesh portion is attached and extending in a longitudinal direction, a support post receiving portion extending in the longitudinal direction, which has an insertion hole formed therethrough in the longitudinal direction and which is inserted into the insertion hole, the support post portion being releasably fixable, and which can be installed outside the frame portion of a jumping apparatus having a frame portion and an elastic portion attached to the frame portion with the longitudinal direction being approximately the same direction as the vertical direction.

[0029] Here, the support part can be releasably fixed by pressing the support part inserted into the insertion hole of the support receiver against the inner wall of the support receiver, etc., using a support receiver that can be installed outside the frame of the jumping apparatus, which has a frame part and an elastic part attached to the frame part, with the longitudinal direction being approximately the same direction as the vertical direction, and an insertion hole that extends in the longitudinal direction and penetrates the longitudinal direction is formed, and the support part can be releasably fixed by pressing the support part inserted into the insertion hole of the support receiver against the inner wall of the support receiver, etc., so that the support part can be fixed and detached more easily than when the support part is directly fixed to the leg.

[0030] In addition, when the post with the mesh portion attached, i.e., the post of the safety net, is inserted into the insertion hole through the opening at the upper end, the length of the mesh portion can be adjusted by making the post protrude or not protrude from the opening at the lower end opposite the opening at the upper end, which allows a greater degree of adjustment of the length of the mesh portion compared to a post receiving part that is not through and has a bottom. Furthermore, since the support post receiving portion can be installed outside the frame portion of the jumping apparatus, it is easy to insert the support post of the safety net into the insertion hole of the support post receiving portion without being hindered by components of the jumping apparatus. Effect of the Invention

[0031] The jumping apparatus according to the present invention allows the safety net to be easily attached and removed. The safety net of the present invention can be easily attached and removed from existing jumping equipment. [Brief description of the drawings]

[0033] Hereinafter, embodiments of the present invention will be described with reference to the drawings for the purpose of understanding the present invention. Fig. 1 is a schematic exploded view showing an example of a jumping implement to which the present invention is applied, and Fig. 2 is a schematic view showing a support post receiving part of the jumping implement to which the present invention is applied. Fig. 3 is a schematic plan view showing a post receiving portion of a jumping apparatus to which the present invention is applied, and Fig. 4 is a schematic cross-sectional view taken along line AA in Fig. 3.

[0034] A jumping apparatus 10 of the present invention shown in FIG. 1 includes a metal or resin frame 20 that surrounds a predetermined area. Here, the frame portion 20 is formed in an annular shape, but it is needless to say that it is not limited to this, and it can also be formed in, for example, a rectangular shape.

[0035] The jumping apparatus 10 of the present invention also includes an expandable portion 30 . Here, the stretchable section 30 has a stretchable jumping mat 31 and a plurality of stretchable coil springs 32. That is, the stretchable section 30 has stretchability. Moreover, since the stretchable portion 30 only needs to have stretchability, it may have, for example, a rubber band instead of the coil spring 32.

[0036] As shown in FIG. 1, the jumping mat 31 is attached to the frame 20 via a coil spring 32 . That is, the expansion / contraction section 30 is attached to the frame section 20 in a state where it is surrounded by the frame section 20 .

[0037] The jumping apparatus 10 of the present invention also includes a spring cover 33 that covers the coil spring 32 of the expansion section 30 . Furthermore, if the stretchable portion 30 has a rubber band, the jumping apparatus 10 of the present invention does not need to have the spring cover 33 .

[0038] The jumping apparatus 10 of the present invention also includes legs 40 . Here, the legs 40 extend in the longitudinal direction and are connected to the lower portion of the frame 20 substantially perpendicular to the frame 20 .

[0039] The jumping apparatus 10 of the present invention also includes a safety net 50 . Here, the safety net 50 is composed of a support portion 51 to which a mesh portion 52 is attached. Furthermore, the support pillar 51 extends in the longitudinal direction.

[0040] In addition, the net portion 52 is attached to the support portion 51 via a net portion attachment cover 52A attached to the support portion 51. In addition, an opening / closing zipper portion 54 is provided on a part of the net portion 52, and by opening the opening / closing zipper portion 54, the user can enter or exit the space surrounded by the safety net 50. When the jumping equipment 10 of the present invention is being used, the opening and closing fastener portion 54 is closed to prevent the user from jumping out of the space surrounded by the safety net 50.

[0041] In addition to being configured to surround the space above the expansion section 30 on all four sides as shown in Figure 1, the safety net 50 can also be configured, for example, so that it does not completely surround all four sides, leaving gaps, or so that it is installed only on the outside of one half of the frame section 20.

[0042] The jumping apparatus 10 of the present invention also includes a support post receiving portion 60 . Here, the support post receiving portion 60 extends in the longitudinal direction, and has an insertion hole 61 penetrating therethrough in the longitudinal direction. Therefore, as shown in FIG. 4, openings 62 communicating with the insertion holes 61 are formed on both ends of the support-post receiving portion 60 in the longitudinal direction.

[0043] As shown in FIG. 3, the opening 62 of the support column receiving portion 60 is substantially circular, and the support column receiving portion 60 is formed in a cylindrical shape, but it is needless to say that the shape is not limited to this. The shape of the opening 62 of the post receiving portion 60 may be, for example, substantially rectangular, and the post receiving portion 60 may be formed in a rectangular cylindrical shape.

[0044] In addition, the support post receiving portion 60 can releasably fix the support post portion 51 of the safety net 50 inserted into the insertion hole 61, and is provided outside the frame portion 20, extending in approximately the same direction as the vertical direction. That is, the post receiving portion 60 is formed with a fixing hole 65 that communicates with the insertion hole 61, and the post receiving portion 60 has a fastener 66 having a screw portion 66B that can be inserted into the fixing hole 65 in a removably manner. Additionally, the threaded portion 66B protrudes from the grip portion 66A. Furthermore, the fixing hole 65 of the post receiving portion 60 communicates with the insertion hole 61 in a direction substantially perpendicular to the direction toward the frame portion 20 .

[0045] Here, the screw portion 66B of the fixing tool 66 is pressed against the support column 51, and the support column 51 is pressed against the inner wall of the support column receiving portion 60, thereby being fixed.

[0046] The support column receiving portion 60 is attached to the outer portion of the leg portion 40 so as to extend in substantially the same direction as the longitudinal direction of the leg portion 40 . Here, as shown in FIG. 1, a support pole receiving portion 60 is attached to the outer portion of each of the eight, i.e. all, legs 40, so that the support pole portions 51 of the safety net 50 are substantially integrated with the legs 40, and the weight balance of the entire jumping apparatus 10 of the present invention is good.

[0047] In addition, the pillar receiving portion 60 can also be attached to the outer part of the frame portion 20 instead of the leg portion 40, extending in approximately the same direction as the longitudinal direction of the leg portion 40; however, attaching it to the outer part of the leg portion 40 allows for more attachment points to be provided, and therefore the pillar receiving portion 60 can be attached more firmly.

[0048] Furthermore, the post receiving portion 60 is attached to the leg portion 40 so that the upper end of the post receiving portion 60 is at approximately the same height as the upper surface of the frame portion 20 . Here, as shown in FIG. 1, the pillar receivers 60 are attached to the legs 40 so that the upper ends of all eight of the pillar receivers 60 are at approximately the same height as the upper surface of the frame portion 20. Therefore, compared to a case in which the pillar receivers 60 are attached to the legs 40 so that the upper ends of some of the pillar receivers 60 are at a lower height than the upper surface of the frame portion 20, or the pillar receivers 60 are attached to the legs 40 so that the upper ends of some of the pillar receivers 60 are at a higher height than the upper surface of the frame portion 20, the overall balance of the jumping apparatus 10 of the present invention can be achieved. Therefore, the load is applied evenly to the pillars 51, and the jumping apparatus 10 of the present invention is less likely to warp.

[0049] In addition, the post receiving portion 60 can also be attached to the leg 40 so that the upper end of the post receiving portion 60 is at a lower height than the upper surface of the frame portion 20. However, if the post receiving portion 60 is attached to the leg 40 so that the upper end of the post receiving portion 60 is at approximately the same height as the upper surface of the frame portion 20, the position of the post receiving portion 60 is closer to the point of the safety net 50 where the load is applied than if the upper end of the post receiving portion 60 is at a lower height than the upper surface of the frame portion 20, making it easier for the post receiving portion 60 to support the safety net 50 when a load is applied, and making it easier for the safety net 50 to withstand large loads.

[0050] In addition, the pillar receiver 60 can also be attached to the leg 40 so that the upper end of the pillar receiver 60 is at a higher height than the upper surface of the frame portion 20. However, if the pillar receiver 60 is attached to the leg 40 so that the upper end of the pillar receiver 60 is at approximately the same height as the upper surface of the frame portion 20, the center of gravity of the jumping apparatus 10 of the present invention will not become higher, so the jumping apparatus 10 of the present invention will be less likely to shake, and the user's body will not come into direct contact with the pillar receiver 60, thereby avoiding damage to the pillar receiver 60.

[0051] Moreover, the support column receiving portion 60 is detachably attached to the leg portion 40 . 2, two fixed anchor bolts 63 attached to the outer portion of the support column receiving portion 60 pass through the leg portion 40, and the fixed anchor bolts 63 are fixed with fixed nuts 64. A spherical washer 63A is disposed on the opposite side to the fixed nuts 64 to stabilize the fixed anchor bolts 63.

[0052] When removing the support column receiving portion 60 from the leg portion 40 , the fixing nut 64 is loosened and the fixing anchor bolt 63 is pulled out from the leg portion 40 .

[0053] Since the pillar receiving part 60 is attached to the leg 40 by a fixed anchor bolt 63 that passes through the leg 40 and a fixed nut 64, the pillar receiving part 60 is less likely to move up, down, left, or right and is more stable than when the pillar receiving part 60 is detachably attached to the leg 40 by, for example, a clamping piece.

[0054] In addition, the post receiving portion 60 can be fixed so that it does not come off the leg 40; however, if the post receiving portion 60 is attached to the leg 40 so that it can be attached and detached freely, the post receiving portion 60 can be attached only to the leg 40 to which the safety net 50 is to be attached, thereby making efficient use of the post receiving portion 60 and realizing a variety of arrangements of the safety net 50. In particular, the fixed anchor bolts 63 and the fixed nuts 64 allow the post receiving parts 60 to be stably and detachably attached to the legs 40, while allowing the safety net 50 to be positioned in a variety of ways.

[0055] In addition, the length of the pillar receiving portion 60 is approximately 1 / 3 of the length from the top surface of the frame portion 20 to the ground surface of the leg portion 40, but it is of course not limited to this length and can be, for example, approximately 1 / 2 of the length from the top surface of the frame portion 20 to the ground surface of the leg portion 40.

[0056] In addition, the length of the post receiving portion 60 can be approximately 1 / 4 of the length from the top surface of the frame portion 20 to the ground surface of the leg portion 40, but it is better to make it at least 1 / 3 of the length from the top surface of the frame portion 20 to the ground surface of the leg portion 40, because when the post portion 51 of the safety net 50 is inserted into the insertion hole 61 from the opening 62 at the upper end of the post receiving portion 60 and inserted into the post receiving portion 60 so that the post portion 51 protrudes from the opening 62 at the lower end opposite the opening 62 at the upper end, the length of the post receiving portion 60 increases the contact area between the post portion 51 and the post receiving portion 60, and even if a large load is applied to the safety net 50, the post portion 51 of the safety net 50 is less likely to be subjected to partial load, making it easier to withstand the large load.

[0057] In particular, when the support pole receiving portion 60 is attached to the leg 40 so that its upper end is at approximately the same height as the upper surface of the frame portion 20, the length of the support pole receiving portion 60 is approximately 1 / 3 of the length from the upper surface of the frame portion 20 to the ground surface of the leg 40, thereby ensuring the distance between the lower end of the support pole receiving portion 60 and the ground, and by making the support pole portion 51 of the safety net 50 protrude from the lower opening 62 and shortening the length of the portion of the support pole portion 51 protruding from the upper opening 62, it is possible to make the support pole portion 51 less likely to bend even if the safety net 50 receives an impact and to lower the center of gravity of the entire jumping apparatus 10 of the present invention.

[0058] FIG. 5 is a schematic diagram showing an example of a state in which the posts of a safety net are inserted into the post receiving parts of a jumping apparatus to which the present invention is applied. The post receiving portion 60 has an insertion hole 61 and openings 62 communicating with the insertion hole 61 at both longitudinal ends, so that the post portion 51 of the safety net 50 is inserted into the insertion hole 61 through the opening 62 formed at the upper end of the post receiving portion 60. In addition, the end of the support pole portion 51 of the safety net 50 can be protruded from an opening 62 formed at the lower end of the support pole receiving portion 60 to adjust or shorten the length of the mesh portion 52 of the safety net 50.

[0059] Therefore, the height of the safety net 50 can be adjusted to an appropriate height for the average height of users without replacing the safety net 50. In other words, if the height of the safety net 50 is too tall for the average height of users when the ends of the support pole portions 51 of the safety net 50 do not protrude from the openings 62 formed at the lower end of the support pole receiving portion 60, the ends of the support pole portions 51 can be made to protrude from the openings 62 formed at the lower end of the support pole receiving portion 60, thereby shortening the length of the portion of the support pole portion 51 protruding from the opening 62 at the upper end, i.e., the length of the portion of the mesh portion 52 of the safety net 50.

[0060] On the other hand, if the height of the safety net 50 is too low for the average height of users when the ends of the support poles 51 of the safety net 50 protrude from the openings 62 formed at the lower end of the support pole receiving portion 60, the length of the mesh portion 52 of the safety net 50 can be increased by not making the ends of the support poles 51 protrude from the openings 62 formed at the lower end of the support pole receiving portion 60.

[0061] The safety net of the present invention comprises a safety net 50 such as that provided in the jumping equipment 10 of the present invention, and a support post receiving portion 60 such as that provided in the jumping equipment 10 of the present invention.

[0062] That is, the safety net of the present invention has a support portion. Here, the net portion is attached to the support portion, and the support portion extends in the longitudinal direction.

[0063] The safety net of the present invention also includes a post receiving portion. Here, the support post receiving portion extends in the longitudinal direction, and has an insertion hole passing through in the longitudinal direction. In addition, the support post receiving portion can be freely releasably fixed to the support post portion inserted into the insertion hole, and is configured so that it can be installed outside the frame portion of existing jumping equipment while extending in approximately the same direction as the vertical direction.

[0064] That is, the support post receiving portion is configured so that it can be attached to the outer portion of the leg of an existing jumping apparatus in a state in which it extends in approximately the same direction as the longitudinal direction of the leg. The support column receiver is configured so as to be detachably attached to the leg.

[0065] Existing jumping apparatuses have legs that extend in the longitudinal direction and are connected to the lower part of the frame, generally perpendicular to the frame. Furthermore, existing jumping equipment has a stretchable part attached to a frame.

[0066] As described above, since the jumping apparatus 10 of the present invention is equipped with the support pillar receiving portion 60, the support pillar 51 can be freely releasably fixed by, for example, pressing the support pillar 51 inserted into the insertion hole 61 of the support pillar receiving portion 60 against the inner wall of the support pillar receiving portion 60, and therefore the support pillar 51 can be fixed and detached more easily than when the support pillar 51 is fixed directly to the leg 40.

[0067] Therefore, in the jumping apparatus 10 of the present invention, the support members 51 to which the net members 52 are attached, i.e., the safety net 50, can be easily attached and detached. As a result, the jumping equipment 10 of the present invention allows the installation of the safety net 50 in a shorter time than before, preventing the jumping equipment from being used without the safety net installed due to the time required for installing the safety net as in the past, and preventing the user from falling from the jumping equipment 10 of the present invention.

[0068] In addition, since the safety net of the present invention also has a post receiving portion, the post portion can be freely releasably fixed by, for example, pressing the post portion inserted into the insertion hole of the post receiving portion against the inner wall of the post receiving portion, so that the post portion can be fixed and detached more easily than when the post portion is fixed directly to the leg.

[0069] Thus, the safety net of the present invention can be easily attached and removed from existing jumping equipment. As a result, even with existing jumping equipment, the safety net of the present invention can be attached to the jumping equipment in a shorter time than conventional safety nets, preventing the jumping equipment from being used without the safety net attached due to the time required for attaching the safety net as in the conventional case, and preventing the user from falling off the jumping equipment.
