JP2006043396A - Curved dumbbell - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a curved dumbbell capable of evenly increasing muscle strength by alternately applying weight, heavy and light, to the arm because weights at both sides of a grip are located above or below the grip apart therefrom and vary in weight applied thereto according to its turning angle. <P>SOLUTION: In the curved dumbbell, a shaft 2 is composed of rounded bellows 3 freely adjustable in bending angle. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

Detailed Description of the Invention

[Technical field to which the invention belongs]
In the present invention, the angle of the radius can be freely changed and adjusted by the bellows while the shaft is bent. Therefore, when you hold it in your hand, the weight on both sides will be away from the position of the hand, and it will be in the upper or lower position, and the gravity will change depending on the turning angle, so weight will be added alternately heavy and light, It is related to a curved dumbbell that can apply muscle strength evenly.

[Conventional technology]
In conventional dumbbells, the shaft is straight, so the weights on both sides are always in the same position as the hand, and no matter what the angle, there is no change in gravity. there were.

[Problems to be solved by the invention]
In the present invention, the angle of the radius can be freely changed and adjusted by the bellows of the shaft. Because the weight is at the upper or lower part away from the nigiri hand, weight, light and gravity change depending on the turning angle, so it can be made evenly, making muscle strength, trying to solve the above problems It is.

[Means for solving problems]
As a solution, we will explain it with reference to the diagram.
1, (2) The shaft is bent (3) with a bellows.

〔Example〕
With the structure as above, if you use this,
The angle of the radius can be changed and adjusted freely by the bellows of the shaft.
Then, the weights on both sides are separated from the hand and are on the upper or lower part, and rotate greatly. In addition, the gravity changes depending on the angle of the turning position, so the best shock can be given to the body and flexible muscle strength can be created evenly.

  If you hold one of the weights upward, you will practice Sado pitchig. It is easy to rotate by R, and because it rotates greatly, the centrifugal force becomes large and the force of long throwing is nourished.

  This bellows type curved dumbbell can be formed by fixing the shaft portion. It can also be elastic.

〔The invention's effect〕
In one rotation, the gravity became heavy or light depending on the turning angle, so that it had a good effect on muscle strength, so it was possible to apply evenly flexible muscle strength.
