[Industrial applications]

 The present invention relates to a physical exercise tool developed for exclusive training of grip strength and fingertips.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, various tools for exercising grip strength and finger strength have been devised using springs and the like, and walnut balls and the like have been provided as tools for exercising grip strength.

[0003] As a spring-utilized one, it is known that a side surface substantially <-shaped spring grip, a Z-shaped leaf spring grip, or a coiled spring for forming a gripping force is formed on a ring.

[0004]

[Problems to be solved by the device]

 However, there are not so many specialized training equipment for grip strength and fingertips in the above-mentioned types, and many of them are exercising in appearance and are not aesthetically pleasing. In particular, I couldn't find any special training equipment for fingertip strength. Due to the diversification of sports, for example, as a training device for sports where strengthening the grip of racket sports and strength of fingertips such as climbing are important, it is a dedicated training device for grip and finger strength that is compact and easy to use. Has been requested.

[0007] The coiled spring wheel body is only used for exerting a restoring repulsive force on the force of squeezing the coiled spring wheel body, and is used for fingertip training that requires point contact. There is no function as an instrument.

The present invention was developed as a device for training the grip force and finger force in response to the above-mentioned demands, and has a compact structure capable of training the pressing force and supporting force of the fingertip, and further has an external appearance. The purpose of the invention is to provide a physical training tool with a design aesthetic.

[0007]

[Means for Solving the Problems]

 According to the present invention, a compressible coil spring is provided between the left and right end plates, and the overall shape of the coil spring is a substantially drum-like shape with the center part having a small diameter, and when mounting the coil spring on the end plate, The L-shaped portion for locking and loading the tip of the coil spring is provided on the outer peripheral edge of the back surface of the left and right end plates, and the coil spring is attached by providing a notch formed by gradually inclining from the L-shaped portion. It is a characteristic physical training tool. Further, the left and right end plates are substantially bowl-shaped, and a circular protrusion is provided in the central portion and a small protrusion is provided around the circular protrusion.

The coil spring is vertically compressible and has an appropriate elasticity, and by forming the "spring" shape rather than the cylindrical shape of a puddle, the compression repulsive force in the straight line direction facing the coil spring is provided. Configured as having. Therefore, when pressing the left and right end plates with fingertips, it repels in a straight line direction, and it is safe because it is not distorted and repulsive, and the coil spring does not bend and it is effective for forging. As described above, the physical training device of the present invention has a peculiar effect that can be exercised without loss of repulsive force in the motion of point contact with a relatively small area such as grip strength or finger strength. There is something.

As one of the embodiments of the present invention, it is proposed to load another article having a coating inside a circular protrusion provided at the center of the left and right end plates having a substantially bowl shape. The other article is a magnet that emits a magnetic force. The magnet produces a predetermined magnetic effect by contacting the fingertip or the palm.

Further, since the small projections are formed on the upper surfaces of the left and right two end plates, it is possible to obtain the acupressure effect without slipping when sandwiched by the fingertips. The magnetic effect and the acupressure effect are said to have a synergistic effect, and in this sense, they are also applied to Eastern medicine.

【Example】

 Next, one embodiment of a body training tool according to the present invention will be described with reference to the drawings.

FIG. 1 to FIG. 6 are drawings and cross-sectional views of a body exercising tool according to a normal projection method. The body exercising device in the embodiment is provided with a compressible coil spring 2 between left and right end plates 1 (upper and lower end plates 1 in the figure). The end plate 1 is made of a hard material such as plastic or hard synthetic resin, and is formed into a substantially hemispherical shape or a substantially bowl shape. The left and right end plates 1 have the same shape, which is advantageous in manufacturing. Further, the end plate 1 is provided with an L-shaped portion 11 for locking and loading the tip end portion of the coil spring 2 on the outer peripheral edge of the back surface of the left and right end plates 1 in order to mount the coil spring 2, and further from this L-shaped portion 11. The coil spring 2 is fixedly and firmly adhered and attached by providing a notch 12 formed by gradually inclining shallowly.

On the upper surface of the end plate 1, a protrusion 3 is provided at the center and three small protrusions 4 are provided around the protrusion 3. The projections 3 and the small projections 4 act so as not to slip when pressed by the fingertips, and also provide acupressure and massage effects. The small projections 4 are provided upright at a position that surrounds the projections 3 at the center position of the upper surface in an annular shape at an angular interval of 120 degrees from the center. When sandwiched and pressed by the fingertip, it hits the surface of the fingertip and has an unprecedented pressing effect.

The protrusion 3 provided in the central portion of the end plate 1 has a magnet 6 embedded therein which is covered with a film 5 of synthetic resin or the like. This film 5 has the effect of eliminating the discomfort of direct contact and preventing it from slipping.

The compressible coil spring 2 provided between the left and right end plates 1 is selected to have an appropriate elasticity for strengthening the gripping force and the finger force, but the overall shape of the coil spring 2 is a side surface substantially like a drum. The shape is such that the central part has a small diameter. That is, when viewed from the side surface, the coil spring 2 has a shape in which the intermediate portion is thinly recessed. This recess is effective not only for making it easy to grip, but also for restricting the repulsive force of the coil spring 2 in the linear direction as shown by the arrow B in the figure.

By sandwiching the left and right two end plates 1 with the fingertips and pressing them with the fingertips or the palm, the coil springs 2 are compressed and the repulsive force of the compression coil springs 2 allows training of gripping force / finger force.

It should be noted that the above embodiment is merely an example, and various details such as the material of the end plate 1 can be modified in design and the invention is not limited to this.

The actual size of the body exercising tool shown in the example is 60 mm in overall height and 34 mm in diameter of the end plate.

[0019]

[Effect of device]

 The body exercising device according to the present invention has the constitution and usage as shown in the above embodiment, and therefore has the following unique technical effects. The structure is simple, the manufacturing process can be simplified, and the manufacturing cost can be reduced. It is a dedicated device that can be used for grip strength training and finger strength training. Since the protrusions are formed on the upper surface of the end plate, it is difficult to slip even if it is sandwiched by the fingertips, and the fingertips are acupressure by stimulating the fingertips. is there. Of course, in an exercise in which the end plate is applied to the palm and the other end plate is pressed with the finger, the finger pressure effect of the palm can be performed simultaneously with the training of the grip force. The one provided with a magnet can be expected to have a corresponding magnetic effect due to the magnetic force. The coil spring, which has a small diameter in the middle portion and has a "drum" shape, repels in a linear direction so as to face the pressing action, so that training can be performed without loss of repulsion force. Repulsing in a straight line is safe without twisting your fingertips. Since it is compact, it is easy to use and does not take up much space for storage, making it convenient to carry.

As described above, the body exercising device according to the present invention has a compact structure and can efficiently perform grip strength training and finger strength training, and is of great practical value.
