[Detailed description of the device]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grip strength / finger strength training tool developed for grip strength and fingertip training.

2. Description of the Related Art Conventionally, various devices for exercising grip strength and finger force have been devised by utilizing compression coil springs, tension coil springs, etc., and both grip strength exercising devices and fingertip exercising devices have been developed. It is configured as an independent and separate instrument and is provided as a single unit. In addition, a thin coil-shaped spring formed in a ring is commercially available.

[Problems to be Solved by the Invention] However, since the grip strength training device and the fingertip training device formed as separate and independent devices are often not compact in shape, they are inconvenient for storage and storage. Since they cannot be used in combination, they tend to scatter and dissipate. In addition, many of them are exercising in appearance and are not aesthetically pleasing. Due to the diversification of sports, grip strength and finger strength training equipment are integrated as a training equipment for sports such as free climbing in outdoor sports where finger strength is important. Equipment that can also be trained is required. Also,
The configuration of the commercially available slender coiled spring wheel body is only for the motion of exerting a restoring repulsive force against the force of squeezing the coiled spring wheel body, and for the training of fingertips that require point contact. It does not have a function as an instrument. According to the above demands, the present invention makes it easy to use by fitting a device for training grip strength and a device for training finger pressing force and supporting force in a detachable and compact manner, and It is an object of the present invention to provide a gripping / finger-strength training device which has a compact structure and has an appearance similar to that of Objet and is used as a playground equipment.

SUMMARY OF THE INVENTION The present invention forms a substantially donut-shaped ring body with a gap provided on the outer peripheral side by a spiral spring, and is vertically compressible in the space of the center hole of the ring body. It is a grip and finger training device with a shaft body with various elasticity attached to it in a removable manner. The substantially donut-shaped ring body has a structure in which a spiral spring is connected in an annular shape without forming a gap, or a spiral spring is connected in an annular shape with a gap on the outer peripheral side. The shaft body, which is an elastic body that can be compressed in the vertical direction, is formed of a compression coil spring, a hollow rubber body, or the like. The substantially donut-shaped body itself can perform a gripping exercise to be held by a hand and a massage exercise to be rolled by being worn on a wrist or the like. The shaft body, which is elastic in the longitudinal direction and has elasticity, has a compressive repulsive force by itself, and thus serves as a finger exerciser that is pressed by the fingertips from above and below. Further, in the state where the shaft body having elasticity that is vertically compressible is fitted in the center hole space portion of the ring body, the ring body is expanded by filling the center hole space portion with the shaft body. The repulsive force when gripping is very strong. Similarly, when the shaft body is pressed in a state where the shaft body is fitted to the infusion body, the shaft body has a strong repulsive force due to the resilience of the ring body in addition to its own elasticity. The grip strength / finger strength exercising device of the present invention is capable of exercising several kinds of strength and weakness because repulsive forces having different strengths are generated by combining the same tools. According to one embodiment of the present invention, both ends of a spiral spring are connected to each other to form a substantially donut-shaped ring body, and a compression coil spring is sandwiched between two end plates in a central hole space portion of the ring body. We suggest that you attach and remove the shaft body that is worn as a training tool for fingertips. Specifically, a spiral dough spring forms a substantially donut-shaped ring body, and a shaft body formed by sandwiching a compression coil spring between two end plates can be freely inserted into and removed from the space of the center hole of the ring body. A spherical body such as a bell or a ball is movably inserted inside the ring body, the compression coil spring of the shaft body is covered with a synthetic resin film, and a small protrusion is formed on the upper surface of the two end plates. It is a grip / finger strength training device characterized by providing an appropriate number. If you insert the shaft into the ring and grasp the ring, the spiral springs will overlap in one direction and fall down to reduce the external size of the ring, so the restoring force of the spiral spring will occur and you can train the grip strength. . Also, if the shaft body is still inserted in the ring body, or if the shaft body is removed from the ring body and the two end plates are clamped and pressed by the fingertips, the repulsive force of the compression coil spring and the spiral spring causes the finger force. Can be trained. The compression coil spring is covered with a synthetic resin film to enhance the sound deadening effect, and small protrusions are formed on the upper surfaces of the two end plates to prevent slipping and a massage effect when pinched by the fingertips. One or two bells, balls, etc. are inserted in the cavity so that they can be freely floated, and the strength of the grasping force is judged and the monotonous exercise is given auditory and visual changes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a grip / finger strength training device according to the present invention will now be described with reference to the drawings. FIG. 1 shows a wheel body 1 and a shaft body 2.
FIG. 2 is a front cross-sectional view showing a state in which the
It is a perspective view which shows the state which is using the shaft body 2 removed from FIG. In the gripping / finger strength exercising device in the embodiment, both ends of the spiral spring 3 (coil spring) are joined to form a substantially donut-shaped ring body 1, and a spherical body 7 such as a colored ball made of synthetic resin is formed inside. The shaft body 2 is formed by inserting two compression support springs 4 covered with a synthetic resin film 6 between two shaft supporting end plates 5 in the center hole space 9 of the ring body 1 so as to be freely movable. It is inserted. The substantially donut-shaped wheel body has a configuration in which the spiral spring 3 is annularly connected with a wide gap 10 provided on the outer peripheral side. When the ring body 1 is grasped and compressed so as to wrap it with one hand, the outer circumference of the ring body 1 shrinks and the spiral springs 3 overlap in one direction and fall down. Therefore, a restoring force is generated in the spiral spring 3 and training of grip strength is performed. Is possible. The two shaft support end plates 5 of the shaft body 2 are molded into a substantially plug shape with a hard material such as plastic or hard synthetic resin, and a compression coil spring 4 covered with a synthetic resin film 6 is fitted and sandwiched between them. ing. The synthetic resin film 6 is formed by covering the coil spring with a heat-shrinkable film tube and heating it. The shape of the compression coil spring 4 is a shape in which the intermediate portion is thinly recessed when viewed from the side surface, and the outer peripheral curved portion of the spiral spring 3 protruding into the center hole 9 of the ring body 1 is inserted into this recess, and it is relatively firm. Inset. Also in terms of dimensions, since the intermediate portion of the compression coil spring 4 is thicker than the central hole 9 of the ring body 1, it acts so as to widen the spiral spring 3 and is firmly fitted therein. An appropriate number of small projections 8 are provided on the upper surfaces of the shaft support end plates 5 of the two shafts 2 so that they do not slip when pressed by a fingertip and a massage effect can be obtained. The outer surface is matte except for the namespace 11. The namespace 11 is used as a product name display and an advertisement column display. One small protrusion 8 is located at the center of the upper surface of the end plate 5 and surrounds it in a ring shape.
Stands individually. The size of the entire small protrusion 8 contacts the fingertip. If the two shaft support end plates 5 are sandwiched and pressed with the fingertips while the shaft body 2 is still inserted in the wheel body 1, the compression coil spring 4 is compressed and the entire circumference of the wheel body 1 is pressed outward. Due to the expansion, the repulsive force of the compression coil spring 4 and the restoring force of the spiral spring 3 act synergistically to enable hard finger force training. If the shaft body 2 is removed from the wheel body 1 and the two shaft support end plates 5 are sandwiched and pressed by the fingertips, the repulsive force of the compression coil spring 4 provides relatively soft finger force training. Since the compression coil spring 4 is covered with the synthetic resin film 6, even when the wheel body 1 is compressed for grip strength training, the shaft support shaft plate 5 is clamped to compress the compression coil spring 4 for finger strength training. Does not make an unpleasant sound. In addition, a spherical body 7 such as a colored ball made of a synthetic resin is movably inserted into the inner cavity of the ring body 1 so that a rotating sound of the spherical body 7 is generated when the ring body 1 is gripped. In addition, the strength of grip strength is judged by the sound of contact when two or more pieces are put in, and auditory and visual changes are given to repetitive movements that tend to be monotonous. By inserting the two spherical bodies 7, the spherical bodies 7 come into contact with each other when gripping, and a sound is generated, so that the degree of gripping force can be detected. It is also proposed that the spherical body 7 is made of metal to make the contact sound clear, a glass ball with a pattern, or one or more small bells. In addition, in the spiral spring 3,
Since there is the gap 10, the spherical body 7 such as a color ball can be easily seen from the outside. The above embodiment is merely an example, and the material and shape of the shaft support end plate 5, the spherical body 7
Various design changes can be made to the details such as the material, size, number, and length of the compression coil spring 4, and the present invention is not limited to this. The actual size of the grip strength / finger strength training device shown in the examples is as follows. Ring 1 has a diameter of 27 mm
The coiled springs (coil springs) are wound 35 times and are connected in an annular shape. The outer diameter is 70 mm and the diameter of the central hole space is 18 mm. The width of the outer peripheral gap 10 is 5
m. The shaft body 2 has an overall height of 50 mm, the coil spring 4 has a height of 30 mm, the end plate has a diameter of 33 mm, and the small projection 8 is provided.
The outer peripheral protrusion has a height of 2 mm, and the small protrusion at the center has a height of 1 mm. In the state where the wheel body 1 is combined with the shaft body 2, the outer diameter of the wheel body 1 is expanded to 75 mm, and the gap 10 in the outer peripheral portion is 6 mm.
Spread to. As the spherical body 7, a hollow synthetic resin color ball having a diameter of 15 mm was loaded.

EFFECT OF THE INVENTION Since the grip and finger training apparatus according to the present invention has the structure and usage as shown in the above embodiment, it has the following unique technical effects. Although the wheel body and the shaft body have a simple structure, by setting the dimensions in relation to each other, it is possible to provide a training tool capable of various strength and weakness exercises. Since the structure is simple, the manufacturing process can be simplified and the manufacturing cost can be reduced. Not only the grip strength training but also the finger strength training can be carried out in two stages of strength and weakness, so that the training effect is improved. Since a small protrusion is formed on the upper surface of the shaft body, even if it is held by the fingertip, it is hard to slip and stimulates the fingertip to have a massage effect. Since the compression coil spring is covered with a resin film before it is used to enhance the sound deadening effect, you can train quietly. The compression coil spring is covered with a synthetic resin film to ensure smooth contact with the spiral spring. Since the combination of grip strength training equipment and finger strength training equipment is compact, it is easy to use and convenient to carry without taking up space for storage. The appearance is like playground equipment, and by inserting a small bell or a colored ball inside the ring, you can judge the strength of the grip strength, and add auditory / visual changes to the monotonous repetitive motion. It will also happen, so don't get bored. in this way,
INDUSTRIAL APPLICABILITY The grip strength / finger strength training apparatus according to the present invention has a compact structure and is capable of performing not only grip strength training but also finger strength training in two stages, and is extremely practical.
