Description

{Apparatus for user-active tilt adjustable surfing training}

The present invention relates to an active slope variable type surfing exercise training apparatus, and more particularly, to an active slope variable type surfing exercise training apparatus that improves a buffer function during surfing exercise through a ball joint portion and a tension compression portion.

In general, the surfing exercise device refers to a device provided to improve balance and muscle strength by simulating a surfing exercise on land. Here, the surfing exercise device has the advantage of receiving continuous training through pre-training on land prior to using a surfboard used in the sea, and acquiring skill acquisition, physical strength enhancement, and surfing posture stability in a short time.

In recent years, research on such surfing practice devices is developing very rapidly, and the trend is spreading to the general public, mainly in surf clubs and health clubs, mainly in the United States, and equipment incorporating virtual reality (VR) technology is also used. It is expanding.

On the other hand, some configurations for surf training equipment have been disclosed in the related art, but development is insufficient in Korea. In detail, in the conventional surf training equipment, a tilt variable device including a compressed air tube, an air tube fixing device, and a steel frame is provided under the surfboard. In addition, when the user changes its own load, the surfboard is inclined, and the inclination is changed as the air tube is pressurized.

However, conventional surfing training equipment has a problem in that when air pressure leaks inside the air tube, the tilt angle cannot be adjusted smoothly, resulting in a decrease in athletic performance and a need for recharging the air pressure, thereby reducing the convenience of use. Moreover, there is a problem that the surfboard is separated from the air tube when the air tube is recharged.

In particular, there is a problem in that the safety of use is deteriorated, such as a safety accident or damage to the surfboard as the surfboard deviates from the air tube due to air pressure leakage during the practice using the surfing training equipment.

In addition, the safety bar 60 is provided in a pair so that the user can grip during the surfing exercise, and is disposed on both sides of the surfboard 10 in the width direction, but the ends are connected to the side edges of the base unit 50. desirable. In this case, the safety bar 60 may be provided with a metal or synthetic resin having a strength greater than or equal to a preset value so as to stably provide support when the user grips.

In detail, each of the safety bars 60 is a parallel bar disposed at a standard height corresponding to the position of the user's hand during a surfing exercise, and each integrally extends downward from both ends of the parallel bar so that the lower end thereof is the base part 50 It may include a pair of vertical bars connected to the side rim of the. That is, the safety bar 60 may be provided in a'C' shape, and each end may be disposed downward to be connected to a side edge of the base part 50. Of course, the connecting portion of the parallel bar and the vertical bar may be provided in a rounded curved shape, and the parallel bar and the vertical bar may also be formed to be round.

For example, the lower end of the vertical bar is connected to the side edge of the base part 50, but the position of the vertical bar expands to the outside in the front and rear direction and the width direction of the surfboard 10 and reaches the upper end again. The surfboard 10 may be formed in a form that contracts in the front-rear direction and in the width direction.

In addition, at the lower end of the vertical bar of each of the safety bars 60, a first fixing plate 61 in the shape of a flat plate that extends integrally with the vertical bar so as to be seated on the upper surface of the base part 50 and fastened with a bolt is formed. desirable.

Here, it is preferable that the first fixing plate 61 is mounted on the upper surface of the base portion 50, and a plurality of first fixing holes are formed through the first fixing plate 61 in the vertical direction.

Moreover, it is preferable that a second fixing plate 62 having a flat plate shape is further provided under the base part 50 corresponding to the position of the first fixing plate 61. In this case, it is preferable that a plurality of second fixing holes are formed through the second fixing plate 62 in the vertical direction.

In addition, it is preferable that a third fixing hole is formed vertically through one side of the base portion 50 corresponding between the first fixing plate 61 and the second fixing plate 62.

Through this, as the first fixing hole, the second fixing hole, and the third fixing hole are aligned with each other and then bolted, the safety bar 60 and the base part 50 can be fixed to each other. have.

In this way, as the second fixing plate 62 is further provided to mediate the fastening of the safety bar 60 and the base part 50, the coupling between the safety bar 60 and the base part 50 is Since it is kept more robust, the separation of the safety bar 60 is prevented in advance even with a strong external force by the user, so that durability can be remarkably improved.

At this time, the terms such as "include", "comprise", or "have" described above mean that the corresponding component may be present unless otherwise stated, excluding other components. It should not be construed as being able to include other components. All terms, including technical or scientific terms, have the same meaning as commonly understood by one of ordinary skill in the art, unless otherwise defined. Terms generally used, such as terms defined in the dictionary, should be interpreted as being consistent with the meaning of the context of the related technology, and are not interpreted as ideal or excessively formal meanings unless explicitly defined in the present invention.

As described above, the present invention is not limited to each of the above-described embodiments, and it is possible to be modified and implemented by those of ordinary skill in the art without departing from the scope claimed in the claims of the present invention. And, these modifications are within the scope of the present invention.
