Description

Jumping and spinning interventions {Trampoline}

The present invention relates to a fitness device, and more particularly, to a twist exercise course in which a user jumps up and down a body while twisting the body to the left and right to perform a rotational twist exercise.

In the field of the present invention, in order to synchronize rotation and vertical motion,

(Down-right turn) while moving upwards (down-right turn) while moving upwards (down-right turn) while lowering downward (down-right turn) And a left-turn stroke) are completed in one cycle.

In the problem, the direction is changed at the bottom dead center where the base is located at the lowest point, and the rotation continues in the same direction at the top dead center where the base is located at the peak. Therefore, it is possible to change the position to another bottom dead point only after attempting a twist jump from the bottom dead center and beyond the top dead center. As a result of this action, regardless of the degree of mastery of the user, it is difficult to go beyond the determined upper limit regardless of the degree of exercise desired by the user.

To solve the above difficulties and risks, there is disclosed a mechanism for performing a two-stroke one cycle in which the motion starts at the bottom dead center and the left and right are rotated to gradually guide the up and down movements.

However, since a large number of connectors are hinge-joined, the manufacturing cost is high due to the complicated configuration, and the endurance is weak due to an excessive load applied to the hinge shaft of the mechanism.

The present invention has been made in view of the above problems,

The rotation is continued in the same direction at the bottom dead center, the rotation direction is switched at the top dead center, and the top dead center is determined by itself in accordance with the level of the user,

And it is an object of the present invention to provide a structure which can jump without taking the same configuration as a plurality of connectors and can take a robust and simple configuration to provide an advantageous implementation in terms of durability and cost.

As a means for solving the above-mentioned problem,

A support frame; A first contact portion; A second contact portion; A rotating shaft; Swing bar; And a swing guide.

The support frame is provided with a rotation shaft bearing to which the rotation shaft is to be supported, and the swing guide is hinged.

Wherein either the first contact portion or the second contact portion receives a load of the user; And the other transfers loads to the outside.

One end of the rotating shaft is connected to the first contact portion and is supported by the rotating shaft bearing to become a left and right rotating shaft of the first contacting portion and an up and down coiling shaft of the up and down sliding.

The swing bar is connected to the other end of the rotating shaft.

One end of the swing guide is hinged to the support frame, and the other end is hinged to the swing bar.

The connection may be formed as a body initially or as a separate body and assembled; Attach; Fixed.

The hinge jointing means that the hinge joint is directly or indirectly connected in a refracting manner.

Through the above-described configuration, the contact portion contacting the user continuously rotates in the same direction at the bottom dead center and the rotation is switched in the opposite direction at the top dead center.

Therefore, even if the user does not have a separate elastic body, the swing guide can be twisted up to the top dead center due to the artificial torsion torque of the user or the rotational force generated by the falling of the user due to the inertia to rotate in the same direction at the bottom dead center.

In addition, since the top dead center is determined by the user in a desired and adaptable position, the top dead center can be used freely.

According to the configuration proposed by the present invention,

Since the rotation direction is switched at the top dead center and the rotation continues in the same direction at the bottom dead center, it is possible to start the left-right rotation and the up-and-down jumping movement in such a manner that the left and right amplitudes are slightly amplified from the bottom dead center.

Accordingly, it is very easy to carry out the rotary jumping motion, and the top dead center of the desired height can be selected by itself to meet the user's body condition.

In addition, the jump can be performed only at a desired height, so that the intensity of the exercise can be adjusted as needed.

Especially. It is possible to jump back to the top dead center by changing the direction in which the energy stored in the gravitational drop can be diverted by using the same principle as the swing without the need for an elastic body for restoring the user's load on the floor.

In the production and production, it is possible to carry out a construction which is robust and simple and which is advantageous in durability and production cost.
