A joining piece, installed on an edge of the leaping board, is inserted and installed in the first through-hole of the buckle member. The elastic ring is wound around the base frame through the second through-hole, while the elastic ring is hung on the holding post on one side and is maintained, and then is hung on the holding post on the other side to join the base frame to the leaping board. Accordingly, since the leaping board can be fixated to the base frame in an easy manner by using the buckle member, installed on the edge of the leaping board, and the elastic ring inserted in the buckle member and fixated, the risk of an existing device injuring a person by a metal component can be eliminated. In addition, the leaping board can be attached and detached in a very easy manner. Therefore, the device for fixating a leaping board of a trampoline has a merit of convenient installation and removal.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a jumper fixing device for a trampoline,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a trampoline capable of enjoying play by performing repetitive jumping operations, and more particularly, to a trampoline fixture mechanism of a trampoline configured to be easily installed on a base frame.

As already well known, a trampoline is a kind of play apparatus having a jump board connected with an elastic body such as a spring in a base frame having a predetermined height, and a user performs a jumping operation successively at an appropriate height in a state of being on a jump board It is possible to enjoy the play by the reaction force of the elastic body.

Such a trampoline tends to be used in an indoor space as well as a playground because it can impart a fun to a child during a growth period and improve a flexibility or a sense of balance of the body.

However, existing trampolines often fall because they are not in the center and fall easily due to the repulsive force of the elastic body acting differently depending on which part of the jumping plate is stepped on.

Regarding such a riding apparatus, in the case of the "trampoline holder" disclosed in the Japanese Patent Laid-Open Publication No. 2008-0066183, the transverse pipe, the supporting pipe, the connecting sleeve, The lock, the locking device and the connecting sleeve are combined to improve the safety of use of the trampoline, as well as to assemble and disassemble it so that it can be easily stored after use.

However, this is merely a provision of a connection sleeve for simply connecting the transverse pipe and the support pipe, and there is a drawback that the elastic member such as a spring is exposed as it is, and there is a great possibility that the pipe will be injured.

In addition, Japanese Laid-Open Patent Publication No. 2014-0013458 discloses a technique in which a piezoelectric element is installed on the bottom surface of a conventional trampoline to convert kinetic energy into electric energy, and a battery for storing the electric energy is provided. Although it is possible to produce environmentally friendly electric power while enjoying it, it has been made possible to reduce environmental pollution. However, in this case, it was designed to be used in the form of a playground of children, so that it was difficult to realize electric power production realistically.

On the other hand, in the case of the "jumping play bar" disclosed in Japanese Patent Registration No. 0666280, the addition of the bar portion to the frame constituting the main body of the trampoline adds an effect of jumping movement as well as a bar movement and has an effect of ensuring stability by a safety fence .

However, since the bracket for fixing the iron bar is formed integrally with the frame itself, when the jump play is performed at the jump-off portion on the frame, the other player can not play the bar iron properly because of the heavy swing of the bar, A child who enjoys jumping play around the whole circumference can cause a bigger safety accident if it is caught or bumped.

In addition, in the above-described conventional trampolines, when a springboard is to be mounted on a base frame, it is necessary to tighten the spring with a very strong force by using a separate device because it is mediated by a spring or an elastic body. It is impossible to store it and it is difficult to store it.

Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings. However, the specific structures and functions of the present invention are not limited to the embodiments described herein.

1 to 4A and 4B are diagrams for explaining the most basic example of a trampoline to which the present invention is applied. In the case of a typical trampoline, a base frame 10 and a jumping board (30).

The base frame 10 is composed of a horizontal rod 11A and a vertical bar 11B which are arranged in parallel to each other using a normal cylindrical pipe and vertically connecting pipes 12 Or can be assembled by using separate brackets.

A safety handle (not shown) capable of assisting jumping play can be fixed to the upper side of each of the connection pipes 12, and a support leg 13 having a threaded periphery around the outer periphery of the tip can be fastened to the lower side So that the height can be arbitrarily set.

The elastic plate 31 has a plurality of elastic bands 31 sewn at predetermined intervals on the four sides of the base 30. The elastic bands 31 are formed by the transverse bar 11A and the vertical bar 11B.

A support base 24a having an arcuate groove 23a and a band fixture 25 having a U-shape by the body 24b are fixed to the lower ends of the transverse bar 11A and the vertical bar 11B by screws 26 So that the elastic band 31 can be always kept in the position to inhibit the flow of the spring 30.

With this configuration, the connection pipe 12 can be vertically arranged and fixed to the connecting portion of the horizontal bar 11A and vertical bar 11B for constituting the base frame 10 (see FIG. 2A).

In this state, the six elastic bands 31 sewn to the hopper 30 are sandwiched by the transverse bar 11A and the vertical bar 11B, so that the state where the hopper 30 is bound to the base frame 10 (See FIG. 2B).

As shown in FIGS. 1 and 3, a balance (not shown) can be held on the upper and lower sides of the connecting pipe 12 to maintain a balance during jumping operation. .

4A and 4B, a separate band fixture 25 is mounted on the lower side of the transverse bar 11A and the vertical bar 11B constituting the foundation pipe 10, It is possible to prevent the light beam from deviating from its position.

That is, the band fixture 25 is formed with a support base 24a having circular arc grooves 23a on both sides of the body 24b and fixed to the bottom surface of the transverse bar 11A or the vertical bar 11B, So that the flow of the elastic band 31 can be suppressed.

At this time, the band fixtures 25 may be all fitted according to the number of the elastic bands 31, but they may be provided so as to face each other.

However, in the above-described trampoline, since the elastic bands 31 must be fixed to the base frame 10 with the elastic bands 31 sewn at regular intervals on the base 30, There is a problem that it is cumbersome.

In addition, since the elastic band 31 is self-resilient, it is difficult to manually perform the elastic band 31, and thus, the auxiliary plate 30 and the base frame 10 are bound to each other by using an auxiliary equipment in the course of manufacture , The general user could not dismantle after using the trampoline, so he had to keep it.

The present invention can provide a trampoline improved in the assembling method by considering such a problem. 5 to 7A and 7B, a base frame 40 and a base plate 40 provided on the base frame 40 are provided with separate fastening means interposed between the base frame 40 and the base plate 40, It is possible to easily mount the jumping-off plate 50 on the apparatus.

That is, the base frame 40 is composed of a horizontal bar 41A and a vertical bar 41B arranged in parallel to each other by using a normal cylindrical pipe as described above, And the pipe 42 forms a rectangular frame.

The transverse bar 41A and the vertical bar 41B may be folded to each other via known folding means or may be assembled by attaching a separate bracket to each corner.

In addition, a safety handle or a support leg (not shown) capable of assisting jumping play can be mounted on the upper and lower sides of each of the connection pipes 42 to set the height arbitrarily.

The binding means is composed of a buckle member 60 and an elastic ring 70 which are disposed between the base frame 40 and the spring plate 50 to bind them together.

The buckle member 60 has first and second through holes 63a and 63b divided by the frame 61 and the partition wall 62 on both sides of the buckle member 60 and a pair of The latching pillars 64a and 64b are protruded.

A protruding step 65 is formed at an end of each of the latching pillars 64a and 64b to more reliably hold the elastic ring 70. The side wall of each of the latching pillars 64a and 64b has a groove (Not shown).

A connecting piece 51 is inserted into the first through hole 63a of the buckle member 60 and can be mounted on the four sides of the spring plate 50.

That is, after the connecting piece 51 is inserted into the first through-hole 63a formed in the buckle member 60, the connecting pieces 51 are sewed by arranging them in the lateral and longitudinal directions on the four sides of the catching plate 50, So that the spring plate 50 can be manufactured.

The connecting plate 51 may be formed in a ring shape and may be bonded to each other without depending on the sewing so that the binding plate 50 can be integrally formed by the connecting piece 51 and the buckle member 60 do.

As shown in Figs. 7A and 7B, each buckle member 60 can be engaged with the base frame 40 by being hooked with the elastic ring 70. Fig.

That is to say, in the state where the elastic ring 70 is held by the latching column 64a formed on one side of the buckle member 60 and the other side of the elastic ring 70 is indicated by the imaginary line, So that the base frame 40 can be wound around the base frame 40 with elasticity after being drawn out through the two through holes 63b.

The base frame 40 and the spring plate 50 can be easily coupled to each other by holding the elastic ring 70 by being pulled and held by the other latching column 64b of the buckle member 60. [

In this way, since the elastic ring 70 can be engaged with each of the buckle members 60 mounted on the jump plate 50 to bind the base frame 40, the jump plate 50 is maintained in a state of having a predetermined elasticity And it can never be released unless it is artificially stripped of the elastic ring 70.

As described above, according to the present invention, since the buckle member mounted on the edge of the buckle plate and the elastic ring fitted and fixed to the buckle member can be used to easily fix the buckle plate to the base frame, And it is easy to install and disassemble the trampoline because it is very easy to remove and adhere the springboard.

Although the present invention has been fully described in connection with the preferred embodiments thereof with reference to the accompanying drawings, it is to be understood that the present invention is not limited thereto. It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
