As shown in FIG. 1, the handle 10 for the strength training device of the present embodiment is composed of two support rods 11 and 11 and two connecting portions 12 and 12 that connect the support rods 11 and 11 in a parallel state. It is configured. A weight portion 13 is integrally provided with each connecting portion 12 of the handle 10, and a dumbbell 100 is configured as a strength training device.

The connecting portion 12 and the weight portion 13 in the present embodiment have a rectangular parallelepiped shape as a whole, and a total of two support rods 11 and 11 are bridged between the rectangular facing surfaces 12a and 12a facing each other. The two support rods 11 and 11 are fixed in parallel.

The support rod 11 of the present embodiment has a substantially round rod shape, and two support rods 11 and 11 are provided in parallel with each other. The outer surface of each support rod 11 is provided with a flat surface 11a that can come into contact with the inside of the user's wrist.

As shown in FIG. 2, the flat surface 11a is provided so as to be inclined by an inclination angle α toward the other support rod 11 with respect to the virtual plane P passing through each axis A of the two support rods 11 and 11. ing. In the present embodiment, the inclination angle α of the flat surface 11a with respect to the virtual plane P is set to 30 °. Further, in the present embodiment, the flat surfaces 11a are provided on both of the two support rods 11 and 11, and these flat surfaces 11a and 11a are parallel to each other. Further, the two support rods 11 and 11 are provided so that their virtual plane P is inclined by an inclination angle β with respect to the bottom surface 12b of the connecting portion 12. In the present embodiment, the inclination angle β is set to about 11 °.

When dumbbell curling is performed using the dumbbell 100 provided with the handle 10, as shown in FIG. 3, the underhand with the user's palm H facing upward causes the two support rods 11 and 11 to be used. The fingertips of four fingers other than the thumb are hooked on the support rod 11A on the back side, and the carpal bone portion on the inside of the wrist is brought into contact with the flat surface 11a of the support rod 11B on the front side. The thumb is placed on the flat surface 11a of the support rod 11A on the back side. Then, the dumbbell 100 is lifted against the vertical load F1, the elbow is bent and stretched, and the forearm is repeatedly moved up and down to mainly perform strength training such as the biceps brachii.

As described above, according to the handle 10 of the present embodiment, the dumbbell 100 is stabilized in a state where the four fingers are hooked on the support rod 11A on the back side and the inside of the wrist is in contact with the flat surface 11a of the support rod 11B on the front side. Since it can be held in, dumbbell curl etc. can be performed without grasping the grip part like the conventional product, and it does not cause early fatigue of the forearm muscle group that contributes to grip strength, and the biceps brachii muscle etc. Strength training can be done efficiently.

Moreover, according to the handle 10 of the present embodiment, since the inside of the wrist is brought into contact with the flat surface 11a, the carpal bones (particularly the pisiform bone and the scaphoid bone) on the inside of the wrist are surely hit. The load of the dumbbell 100 can be supported in the contacted state. Therefore, there is no possibility that the blood vessels and nerves inside the wrist are pressed by the dumbbell load, and the strength training of the upper arm and the like can be performed.

Further, in the handle 10 of the present embodiment, since the flat surface 11a provided on one support rod 11 is inclined toward the other support rod 11 with respect to the virtual plane P, the user's palm H is naturally made. The inside of the wrist can be brought into contact with the flat surface 11a of the support rod 11B on the front side by hooking four fingers on the support rod 11A on the back side while maintaining the open state. It is possible to perform muscular strength training of the upper arm and the like without imposing an unnecessary burden on the upper arm.

In the present embodiment, the inclination angle α of the flat surface 11a with respect to the virtual plane P is 30 °, but the inclination angle α of the flat surface in the present invention can be changed in the range of 15 ° to 60 °. When this inclination angle α is less than 15 ° or more than 60 °, the edge of the flat surface 11a easily comes into contact with a part other than the carpal bone on the inside of the wrist, which puts an unnecessary burden on the user's palm H and wrist. In addition, it becomes impossible to stably hold strength training equipment such as dumbbells. The inclination angle α can be appropriately set according to, for example, the distance between the support rods 11, the thickness and cross-sectional shape of each support rod 11, the width of the flat surface 11a, and the like, and the range of the inclination angle α is preferably set. It is 15 ° to 60 °, more preferably 20 ° to 40 °.

Further, in the handle 10 of the present embodiment, the flat surfaces 11a are provided on both of the two support rods 11, and the flat surfaces 11a are parallel to each other. Therefore, the dumbbell 100 is used by turning it upside down. Also, as shown in FIG. 3, when the fingertips of four fingers other than the thumb are hooked on the support rod 11A on the back side and the inside of the wrist is brought into contact with the flat surface 11a of the support rod 11B on the front side. , The side surface of the thumb can be naturally aligned on the flat surface 11a of the support rod 11A on the back side, and the dumbbell 100 can be held more stably. This also makes it possible to efficiently perform strength training of the upper arm and the like without imposing an unnecessary burden on the user's palm H and fingers.

Further, since the handle 10 of the present embodiment is provided with the two support rods 11 and 11 inclining the virtual plane P with respect to the bottom surface 12b of the connecting portion 12 by an inclination angle β, the handle 10 of the present embodiment is provided.
