Claims (6)

1. 1. A trampoline apparatus comprising: a frame portion surrounding a predetermined range; An elastic portion having elasticity and attached to the frame portion in a state of being surrounded by the frame portion; A leg portion extending in a longitudinal direction and connected to a lower section of the frame portion so as to be substantially orthogonal to the frame portion; a support column portion extending in the longitudinal direction and to which a net portion is attached, and A support column receiving part extending in the longitudinal direction, having an insertion hole extending therethrough in the longitudinal direction, releasably fixing the support column part inserted into the insertion hole, and being provided outside the frame part in a state in which the longitudinal direction is substantially the same as a vertical direction, wherein The support column receiving part is disposed such that an upper end of the support column receiving part is located at substantially the same height position as an upper surface of the frame part.
2. 2. A trampoline according to claim 1 wherein the support column receivers are attached to the outer sections of the legs in a state extending in substantially the same direction as the longitudinal direction of the legs.
3. 3. A trampoline according to claim 2 wherein the support column receivers are detachably attachable to the legs.
4. 4. A trampoline according to claim 1 wherein the length of the support column receiving portion is at least 1/3 of the length from the upper surface of the frame portion to the ground contacting surface of the leg.
5. 5. The trampoline apparatus of claim 1 wherein A fixing hole communicating with the insertion hole is formed in the support column receiving portion, and The support post receiver includes a fastener removably insertable into the securing aperture.
6. 6. A trampoline according to claim 5 wherein the securing holes of the support column receiving portions communicate with the insertion holes in a direction generally orthogonal to the direction toward the frame portion.

Description

Jumping apparatus Technical Field The present invention relates to a trampoline apparatus. In particular, the present invention relates to a trampoline apparatus to which a safety net for preventing a user from falling is attached. . Background The use of the rap (registered trademark) (i.e., a jumping apparatus) has become increasingly popular as an exercise apparatus that allows anyone from adults to children to exercise while playing, and has various effects as follows. (1) High exercise efficiency The jumping motion using the jumping apparatus has a higher exercise efficiency than jogging, and the amount of exercise generated by the jumping motion for 5 minutes corresponds to the amount of exercise generated by jogging 1 km. (2) Enhancing lymphatic flow The bouncing motion can promote the flow of lymph (with the effect of flushing out waste) allowing the body to more easily absorb nutrients. (3) Enhancing muscle strength, torso and brain Since the internal muscles are used to maintain balance and stand upright between jumping and landing, the muscles and torso can be trained. Jumping exercise has the effect of promoting brain development, and has the effect of enhancing "memory", "concentration", and "understanding" as the function of the brain is activated. (4) Preventing osteoporosis By jumping up and down, bone loss is stopped, bone density is stabilized, and fall prevention is achieved. Under such circumstances, various jumping apparatuses have been proposed. For example, patent document 1 describes a jumping apparatus shown in fig. 6. That is, the jumping apparatus 200 described in patent document 1 includes an inner net 201 that extends horizontally and a user can repeatedly jump on the inner net 201, an outer net 202 that extends continuously horizontally at an outer peripheral edge of the inner net 201 and prevents a user who deviates from the inner net 201 from falling during the repeated jumping movement, and a plurality of leaf springs 203 that support the inner net 201 and the outer net 202 substantially vertically and elastically from below. Each leaf spring 203 includes a first leaf spring 203A whose upper end portion is connected to the outer peripheral edge of the outer net 202, a second leaf spring 203B whose upper end portion is connected to the connection portion of the inner net 201 and the outer net 202, and a connection portion 203C which connects the lower portion of the first leaf spring 203A with the lower portion of the second leaf spring 203B. List of references Patent literature Patent document 1 Japanese unexamined patent application publication No. 2002-210035 Disclosure of Invention Problems to be solved by the invention Since the jumping apparatus is an apparatus for a user to perform repeated vertical jumping motions, a supporting portion supporting a jumping surface of the jumping apparatus has a certain height, and the height of the leaf spring 203 in the jumping apparatus 200 described in patent document 1 is 1.5 m. Thus, since there is a possibility that the user may lose his/her balance during the jumping motion and fall from the jumping apparatus, a means for preventing falling is provided. Patent document 1 describes that, in the jumping apparatus 200, the outer net 202 is disposed on the outer periphery of the intranet 201, and even if the user deviates from the intranet 201, the user does not fall from the jumping apparatus 200, and can safely ride on the outer net 202. However, since the user can perform repeated jumping motions in substantially the entire area of the upper surface of the jumping apparatus 200 of patent document 1, there is a possibility that the user may further deviate from the outer net 202 to the outside and fall from the jumping apparatus 200, and thus it is also necessary to attach a safety net in the jumping apparatus 200 in order to prevent falling. In order to attach the safety net, each support column needs to be individually fixed using screws or the like, resulting in the attachment of the safety net being time-consuming. Thus, the trampoline is used without the safety net attached, resulting in an accident in which the user has fallen off the trampoline and is injured. In particular, since the trampoline 200 of patent document 1 does not include the frame portion included in the general trampoline and has a configuration in which the inner net 201 and the outer net 202 are supported by the leaf springs 203, it is difficult to attach the support posts of the safety net. Accordingly, there is a need for a jumping apparatus to and from which a safety net can be easily attached and detached so that a user can safely perform a jumping motion. The present invention has been made in view of the above points, and an object of the present invention is to provide a jumping apparatus to and from which a safety net can be easily attached and detached so that a user can safely perform a jumping motion. Means for solving the problems In order to
