[Detailed description of the device]

[0001]

【Technical field】

 The present invention relates to a structure of a walking trainer for practicing walking or running (hereinafter simply referred to as walking) on an endless walking surface used for improving health and recovering walking ability after illness.

[0002]

[Prior art]

 In such a walking training machine as a body training apparatus, two pulleys rotatably supported in the front and rear of the frame and an upper end of an endless belt stretched between the two pulleys are easily guided by sliding. There is a walking training machine in which an endless walking surface is formed by supporting and descending backward (for example, Japanese Patent Publication No. 53-1690 and Japanese Patent Publication No. 60-160974). There is also a practice device in which the walking surface is formed into a concave curved surface and the inclination is changed (see Japanese Utility Model Laid-Open No. 61-185454).

[0003] These drives the endless belt without relying on external force such as power, but utilize the downhill force on the slope depending on the weight of the practitioner. It is possible to freely control stop and drive according to the exercise and will of the practitioner without using a device. In addition, this has led to a simple structure and a compact and lightweight structure, which enables it to be used in a narrow room, and has been particularly popular in recent years as a household health appliance.

[0004]

[Problems to be solved by the device]

 Although the conventional walking training machine has the above-mentioned characteristics, the running speed of the endless belt is determined by the weight of the trainee, the inclination of the walking surface, and the degree of slippage between the belt and the guide. Therefore, when walking, the endless belt runs and the so-called foot is taken up during the process of moving the foot backward from the stepping on, regardless of the intent and exercise ability of the trainee. Therefore, the practitioner is distant from the actual walking sensation and has an uncomfortable feeling of being urged by the practice device. Not only that, during the one-stroke walking process, an excessive load that is transiently applied to the practitioner may result in poor health.

Further, in the conventional example (Japanese Patent Publication No. Sho 53-1690 and Japanese Patent Laid-Open No. 60-160974), the part from the front end to the rear end of the trainer, that is, from the start end to the end end of the endless belt. , Are formed substantially linearly. For this reason, the foot that is urged by the running of the endless belt and carried to the rear may overstep the end of the endless belt, resulting in unexpected injury such as a sprain or a bone fracture. On the other hand, in another conventional example (see Japanese Utility Model Laid-Open No. 61-18 5454), since the walking surface is formed with a large concave curved surface, the obstacle for the stepping off described above is reduced. However, there is no improvement in the transient burden in the walking process.

The present invention is proposed by attempting to improve the above-mentioned deficiencies of the conventional walking training machine. The purpose of the present invention is to walk without impairing the conventional advantages of being simple, compact and lightweight. The purpose of this study is to provide a structure of a walking training machine that can bring the exercise load and walking sensation during one stroke of the robot to those of an actual walking.

[0007]

[Means for solving the problem]

Two pulleys (3, 3 ′) rotatably supported in the front and rear of the frame (2) and an endless belt (4) stretched between the two pulleys (3, 3 ′). ) Is supported by an easy-to-slide guide (5) and a walking surface (6) is formed which inclines downward toward the rear end pulley (3 ′). (6) is the first slope (G1) having a length substantially corresponding to the stride of the trainee, and the front end of the first slope (G1), that is, the direction opposite to the running direction of the endless belt (4). It is characterized in that a second slope (G2) for changing the inclination angle forward is provided with the top (T) as a boundary.

The intersection angle (θ 1) formed by the first slope (G 1) and the line (h) parallel to the floor surface (F) is approximately 8 to 15 degrees, and the intersection angle (θ 2) is 0. The range is 15 to 15 degrees.

The vicinity of the end pulley (3 ') of the first slope (G1) is characterized in that it is horizontal or slightly elevated toward the end.

The second slope (G2) is characterized in that it has a slope that descends forward and rises toward the pulley (3) at the end.

The guide (5) is rotatably provided around a shaft (71) supported by the frame (2) and is arranged in parallel along a walking surface (6) in a cylindrical roller group (7). , 7, 7, ...).

Further, the guide (5) can be replaced with a large number of roller groups (9, 9, 9, ...) Supported by the frame (2) and arranged in parallel along the walking surface (6). .

[0014]

[Action]

 The second slope (G2) that hits the stepped part of the foot of the walking surface (6) has a different slope from the front first slope (G1) that passes through the top part (T). Therefore, when stepping on, the endless belt (4) Since the component force acting toward the rear of the walking surface (6) to be applied is 0 or very small, the foot does not flow, or it gives a slight resistance to the movement when stepping backward from the foot, Gives the trainee a kinesthetic sensation similar to that of actual walking.

The front end and the rear end of the walking surface (6) are provided with upwardly rising portions, respectively, so that there is no stepping on or stepping off of the rear foot.

[Effect of device]

 The present invention has the above-mentioned structure, and its effect will be described with reference to FIG.

In the walking training machine of claim 1, the position where the trainee walks forward with his / her foot to walk is such that the first slope (G1) in front of the top (T) is inclined. Since the landing is performed on the second slope (G2) which is more gently inclined or descends in the traveling direction, the component force (f1) of the weight (w1) of the practitioner applied to the endless belt (4) with the stepping pressure is applied. At this time, since the other foot is near the rear end of the walking surface (6), the weight of the weight (w2) exerted on the endless belt (4) is balanced with the component force (f2) of the endless belt (4). Gives a walking sensation similar to walking. In addition, since the top (T) forms a gentle convex surface, it is possible to effectively stimulate the sole of the foot intermittently during the process of walking to enhance the exercise effect.

Further, the rising portions (6 ', 6 ") at the front and rear ends can prevent an accident caused by stepping off the walking surface.
