Description

The present invention relates to a training device used for exercise such as strength training and stretching.

Strength training is aimed at maintaining the endurance of skeletal muscles and hypertrophy of muscles, and is specifically performed by applying resistance to the target skeletal muscles. There are various ways to apply resistance in this case, but the ones that use gravity and inertial force, the ones that use the elasticity of elastic bodies such as rubber, and the ones that use resistance by hydraulic pressure or pneumatic pressure are common. is there.

Stretching is also performed in the fields of sports and medicine by pulling and stretching certain muscles of the body for the purpose of keeping them in good condition. Such stretching increases the flexibility of the muscles and widens the range of motion of the joints, and also has a good effect on the mental and physical conditions such as breathing and relieving mental tension.

By the way, Patent Document 1 proposes a training device for performing strength training by utilizing the elasticity of an elastic body such as rubber. This training device connects a grip portion gripped by hand, a comb-shaped portion having a plurality of string-shaped comb-shaped portions sandwiched between a plurality of toes, and these grip portions and the comb-shaped portion. It is configured by integrally molding the string-shaped connecting portion with a flexible material.

According to the above training equipment, it is possible to freely train the sole, toes, plantaris muscle, sole arch, etc., which cannot be trained in daily life.

Japanese Patent No. 6437681

However, the training device proposed in Patent Document 1 is for training mainly the foot-centered parts such as the sole, toes, plantaris muscle, and sole arch, and for example, the abdomen and shoulders. , There is a problem that it cannot be used to increase the muscle strength of other parts such as the inner thigh, upper arm, and hip.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a training device that can be used for strength training and stretching for increasing muscle strength of each part of the whole body.

In order to achieve the above object, the training device (1) according to the present invention has a stretchable string-shaped telescopic portion (2) forming a T-shape in front view and a short portion (2A) of the telescopic portion (2). The first grip portion (3) integrally formed at both ends in the longitudinal direction of the above, and the free end of the long portion (2B) extending at a right angle from the center of the short portion (2A) in the longitudinal direction. It is characterized by including a grip portion (4) of 2.

According to the present invention, the user holds the first grip portion of the training device with, for example, both hands, sandwiches the second grip portion between the crotch, and repeats various operations while holding the grip portion. It is possible to perform strength training and stretching not only around the legs but also other parts (for example, abdomen, hips, bust, shoulders, waist, arms, etc.).

Here, the outer diameters (D1 and D2) of the first grip portion (3) and the second grip portion (4) are set to be larger than the outer diameter (d) of the telescopic portion (2). At the same time, the outer diameter (D2) of the second grip portion (4) may be set larger than the outer diameter (D1) of the first grip portion (3). Further, the first grip portion (3) may be formed into an elliptical spherical shape, and the second grip portion (4) may be formed into a spherical shape.

According to the above configuration, the first grip portion of the training device can be easily grasped and gripped by, for example, and the second grip portion can be sandwiched between the crotch and firmly held. ..

Further, the stretchable portion (2), the first grip portion (3), and the second grip portion (4) are integrally molded with a stretchable elastic body, and SEBS (water addition) is used as the material of the elastic body. Styrene-based thermoplastic elastomer) may be selected.

According to the above configuration, the stretchable portion of the training device can be appropriately stretched by an external force, and the elastic reaction force required for training each part of the body can be obtained by the stretchable portion.

The training device according to the present invention is used not only for the circumference of the legs but also for strength training for increasing the strength of other parts and stretching for adjusting the physical and mental conditions.
