Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention further expands the range of application of the indoor locomotor apparatus commonly used as a device for maintaining and improving health, for rehabilitation of people with physical disabilities or for beauty treatment. The present invention relates to a posture control walking exercise machine used for style training.

[Conventional technology]

 FIG. 3 and FIG. 4 show examples of conventional walkers.

The one shown in FIG. 3 is a frame 2 having four wheels 1 and a rearward-facing U-shaped handrail 3 provided on the upper part of the frame 2.
Enter the frame from behind and walk with the front part of the handrail 3.

As shown in FIG. 4, a front U-shaped handrail 7 is provided on a frame 6 having four wheels 5, and a user 4 walks with both sides of the handrail 7.

The above can move together with a walker on a flat surface such as a room.

In addition, there is a walking exerciser that can perform a pseudo walking exercise at a fixed position.

Although illustration is omitted, such a walking exerciser is mounted on an endless belt and performs pseudo walking at a fixed position.

The driving force of the endless belt in the conventional walking exerciser is obtained by a person's kicking foot or a motor.

A constant speed or variable speed motor is used as the motor, but this is only used for setting the traveling speed of a person.

[Problems to be Solved by the Invention]

In the walker as shown in FIG. 3, the user leans on the front part of the handrail 3 and pushes the walker in the forward leaning state as is apparent in this figure, and the lower limbs are bent and extremely bent. It becomes a bad posture.

The walker shown in FIG. 4 can walk in a posture that is better than that of the walker shown in FIG. 3, but there is a risk that the user will fall forward because the front is open.

In addition, since the walkers shown in FIGS. 3 and 4 move with the user, they cannot be used in a narrow space.

In addition, the conventional walking exerciser that rides on an endless belt and performs pseudo walking has the advantage that it can be used in a small room, but this walking exerciser is a structure that sits on a belt and leans against the front handrail to perform pseudo walking. Therefore, it is just a tool for energy consumption, and from the viewpoint of postural health, aesthetics, rehabilitation, correction of gait disorder, etc.,
It does not have a satisfactory function.

That is, the posture of use thereof is generally tilted forward, pulling the waist and depositing the weight on the front handrail. This leads to a natural walking position and a bad walking posture.

Furthermore, bipedal walking of a person is a continuous action of unconscious movement while being constructed on a high degree of equilibrium movement.

In other words, from the highest degree of aesthetic walking to the walking posture while being hindered by obstacles, it must be reviewed as a problem that includes various correction factors at every stage, so the belt does a simple mechanical movement as in the past. Then the reaction is impossible.

An object of the present invention is to solve the above-mentioned problems of the conventional walker and to provide a posture control walker which can be used even in a narrow place and can perform walking training with a correct posture.

[Means for Solving the Problems]

In order to solve the above problems, the present invention arranges handrails for supporting the upper body of a user placed on an endless belt so as to be located on both sides of the user, and a user with this handrail At the rear of the buttocks, a cross rail is provided for the purpose of correcting the posture of the user, and the driving force of the torque motor that drives the endless belt is controlled by a switch that is operated by the force applied to the handrail of the user so that the walking posture can be improved. Provided is a posture control walking exercising device adapted to obtain a belt movement adapted to the above.

[Operation] The present invention has the above-described configuration, and in use thereof, the user is grasped by the left and right handrails, stands in front of the cross rail, and stands on the belt.

Next, in order to start walking, first, the center of gravity of the body weight is slightly moved forward, the weight is transferred from the forward leg to the left leg, and the forward leg is swung forward.

At the time of the above, since the user applies a force to push down the handrail according to the movement of the center of gravity, the torque motor that generates a torque that balances the static friction of the belt overlaps with the thrust of the hind legs of the user and moves the belt backward. And operates so that the hind legs are pulled back as if by the user.

In this state, the user is compensated for the walking posture by the handrail and the cross rail, and the posture in the abnormal forward bending posture is corrected.

〔Example〕

In the embodiment shown in FIG. 1 and FIG. 2, 11 is a frame, and both sides of a horizontal support plate 13 are fixed to the inside of the upper edges of both side frames 12.
