Description

[Detailed explanation of the idea] "Industrial application field" The present invention relates to grip strength and finger exercise equipment.

``Prior Art'' Generally, there are devices on the market that train grip strength by making a tightly wound spring into a ring shape and deforming the ring.

``Problems to be solved by the invention'' The commercial product mentioned above trains grip strength by simply deforming the ring, and has other functions and effects, such as stimulating pressure points on the palm of the hand, and , the movement of the ring was monotonous and uninteresting. In particular, small objects that could fit in the palm of my hand had little movement and lacked interest.

The present invention eliminates these drawbacks and can be used as a health device for finger exercise, grip strength training, functional recovery training, etc., as well as for stimulating pressure points on the palm, and further improves grip strength with interesting movements. The purpose is to provide exercise equipment.

"Means for Solving the Problems" Therefore, the feature of the present invention is that a coiled spring is formed into a substantially donut-shaped ring body, and a core member is wound in the substantially donut-shaped center hole of the ring body. The reason is that it is made movable.

``Operation'' Since it is configured as described above, when a force is applied to the ring body in the direction of reducing the diameter by gripping force in the palm of the hand, each turn of the coiled spring is deformed in a spiral direction, and due to this deformation, The core member rotates and the ring body contracts in diameter. By repeating this action, grip strength, finger movement, and pressure points are stimulated.

"Example" The following description will be made based on the illustrated embodiments.

In the embodiment shown in FIGS. 1 and 2, reference numeral 1 denotes a ring body, and the ring body 1 is a coiled spring formed into a substantially donut shape.

Reference numeral 2 denotes a core member, and the core member 2 has a substantially doughnut-shaped center portion having a narrow constriction portion 3, and is made of synthetic resin such as rubber. As shown in FIG. 2, the upper and lower ends 4, 4' are formed into rounded and pointed shapes.

Then, the core member 2 is fitted into the center hole 5 of the wheel body 1 and held by the narrowed part 3 of the core member 2.

Further, the upper and lower ends 4, 4' of the core member 2 are connected to the ring body 1.
It is provided so as to protrude upward and downward.

When the product of the present invention is held in the palm of the hand as shown in Fig. 3 and grip force is applied in the direction of diameter reduction, each winding of the coiled spring of the ring body 1 is caused to move in the diameter reduction direction in the direction of arrow A, as shown in Fig. 4. Due to the deformation, force is applied to the core member 2 in the direction of rotation, and the ring body 1 and the core member 2 take on a spiral shape, causing the core member 2 to rotate, so that the ring body 1 contracts in diameter. do.

In other words, each turn of the coiled spring deforms,
The deformation generates an elastic force, resulting in a gripping force movement, and when the gripping force is loosened, each winding of the spring rises to its original state, and in conjunction with this, the core member 2
also rotates and returns to its original position.

As described above, grip strength is trained by continuously repeating the above-mentioned movements. In addition, since the coiled spring is loosely wound on the outside, each ring of the loosely wound stimulates pressure points on the palm and protrudes from the rings 1 at the upper and lower ends 4, 4' of the core member 2. The core member 2 rotates in the palm, and the upper and lower ends 4, 4' provide stimulation to the palm.

Furthermore, it can also be used to press the upper and lower ends 4, 4' of the core member 2 against other pressure points on the body to stimulate the pressure points and relieve stiffness.

Furthermore, as shown in FIG. 5, magnets 6 and 6' may be embedded in the upper and lower ends 4 and 4' of the core member 2 to be used as a magnetic health appliance.

Further, as shown in FIG. 6, if spiral convex portions 7 and 7' are formed on the upper and lower ends 4 and 4' of the core member 2, when the core member 2 rotates in the palm of the hand, it stimulates pressure points on the body. When the core member 2 rotates as described above, the rotation of the spiral protrusions 7 and 7' adds interest to the movement, and the coiled The movement is particularly interesting when combined with the movement of the spring ring body 1.

Furthermore, grooves are provided at the upper and lower ends 4, 4',
It is also preferable to provide a spiral seal or to apply color together with the ring.

``Effects'' The present invention has effectively achieved the intended purpose with the above-mentioned configuration.In particular, the outer part of the invention is made of a coarsely wound coiled spring as a ring body, and the core member is placed in the center hole above and below the ring body. Since it is provided protrudingly, it can be used as a health tool for training grip strength and fingers, or for functional recovery training, as well as stimulating pressure points on the palm of the hand by each of the coarse windings on the outside to relieve stiffness.

In addition, by rotating the upper and lower ends of the core member, stimulation is constantly applied to the palm even during exercise, and by stimulating pressure points on other parts of the body with the upper and lower ends,
It can also be used as a health tool for the entire body, such as to relieve stiffness.

Furthermore, since the wheel body and the core member rotate in a spiral shape by reducing the diameter of the wheel body, the movement is interesting and has a great practical effect.
