I have. The feature of exercise equipment used for health maintenance promotion such as disease prevention and recovery represented by lifestyle-related diseases is that exercise load is not too strong and can be exercised comfortably, and many exercise equipments have been proposed. I have.

[0003] Examples of this type of exercise equipment include a stepping machine for stepping exercise (Japanese Patent Laid-Open No. Hei 6-91018) and a slide machine for sliding exercise (Japanese Patent Laid-Open No. Hei 7-25091).
No. 8) and many exercise mainly using left and right feet and hands.

[0004] The step machine described in Japanese Patent Application Laid-Open No. 6-91018 comprises a step (stepping plate) for mounting a foot attached to left and right pedals, a shock absorber provided for each, and a link mechanism for linking the left and right. In addition, the foot is placed on a foot plate so that the user can perform a stepping exercise.

The slide machine described in Japanese Patent Application Laid-Open No. 7-250918 has a mechanism in which a foot skate slides on two arc-shaped tracks, and a foot is placed on the foot skate to form an arc back and forth. This enables the slide motion.

[0006]

However, in the step machine described in the above-mentioned publication, a load on the ankle is increased since a stepping force is required when raising the foot, and the angle of the ankle is forcibly adjusted to the angle of the step. The burden has to be further increased because they must be matched. Therefore, the amount of exercise of the ankle is increased as compared with the case of performing a normal stepping, and a great stress is applied to the joints and muscles of the feet. Further, in the slide machine described in the above publication, the trajectory of the foot approximates natural walking, but the reciprocating motion of the foot causes great stress on the joints, hip joints and muscles of the feet.

[0007] As described above, conventional walking exercise equipment tends to concentrate stress on the ankles and ankle joints, etc., so that stress is easily applied to the exercise equipment. There is.

The problem to be solved in the present invention is to provide a walking exercise machine which can comfortably exercise comfortably for a long time without local stress concentrated on an ankle, a joint or the like.

[0009]

And a support movably connected to the guide rail and supporting the step in a tread position of a person's foot, wherein a locus of movement of the support by the guide rail is substantially in a vertical plane with a long axis. It is characterized by being substantially elliptical including a short axis and approximating a human walking motion.

According to such a configuration, the trajectory of the pair of left and right steps is set in an elliptical shape, so that it is possible to approximate natural walking. Therefore, large stress during walking is relieved, the exercise load is not too strong, and it is possible to perform exercise that is comfortable and easy to continue. You can have continuous exercise.

From the position g1, the magnet 9b and the magnetic body 10 receive a load due to the attractive force. Therefore, the user can apply a load to his or her walking exercise, and can perform a continuous exercise corresponding to each individual. In addition, by adjusting the position of the magnet 9a in step 5a and the magnet 9b in step 5b, the magnets 9a and 9b and the magnetic body 10 of the guide rail 6c can adjust the load due to the mutual attraction. It can be set to a state where it is hardly worn.

The magnitude of the load can be similarly adjusted by adjusting the position of the magnetic body 10 instead of adjusting the positions of the magnets 9a and 9b.
