Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a running machine for indoor training of the body.

Background Art A running machine is a machine in which a belt is movably mounted on the upper surface of a support such as a roller that itself rotates or is movable, and both ends of the belt are wrapped around the rollers in an endless manner. When one roller is driven to rotate, the belt can rotate endlessly, allowing a person to sit on the belt and practice driving (for example, see Utility Model Application No. 57-95150). reference).

This running machine is often used by sports enthusiasts as well as patients and others for walking training after illness.

Problems to be Solved by the Invention However, according to the conventional running machine mentioned above, the belt is movably mounted on the top of the roller, so when a person runs or walks on the belt, the belt tends to move. In addition to the problem that it is easy to run and the speed tends to be high, there is also a problem that it is difficult to perform effective training because the feel of the sole of the foot is different from actual running or walking. That is, when a person exercises running or walking, it is desirable that the soles of the feet feel good so that they can develop the same feeling as if they were running or walking on the ground or on the floor.

In view of the above-mentioned circumstances, the present invention was developed with the aim of providing a running machine that provides a good feel to the soles of the feet and can provide the same feeling as running or walking on the ground or floor.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a platform having a substantially rectangular flat section, a belt endlessly looped around in the longitudinal direction of the platform, and A running machine was constructed in which a plurality of holes opening to the back surface of the belt were formed at predetermined intervals in the longitudinal direction in the width direction, and a pipe that allowed oil to be supplied from outside the base.

Effect According to the above structure of the present invention, when the belt is rotated and the pipe is oiled, oil drips from the holes and adheres to the back side of the belt, and the oil is spread between the flat surface of the base and the belt. forms an oil film between
Reduce friction between the two. Therefore, since the belt rotates on a platform that itself is stationary,
The feel of the soles of the feet of the person doing the training produces the same feeling as running or walking on the ground or floor, promoting effective training.

Examples Examples will be described below based on illustrated examples. 1 is a plan view, FIG. 2 is a sectional view taken along line AA in FIG. 1, and FIG. 3 is a sectional view taken along line BB in FIG. 1.

As shown in the figure, the platform 1 has a substantially rectangular flat part 2 that can be placed and fixed under the floor, and a belt 3 is rotatably supported on the upper surface of the flat part 2. Rollers 4 and 4a to be moved are rotatably supported on both ends of the platform 1, and an electric motor 5 such as a geared motor is directly connected to the shaft of one roller 4, and is connected to a housing 6 near the step plate 6.
It is installed in a. A pipe 7 is disposed in the width direction of the platform 1, and as shown in FIG. The holes are bored at intervals, one end is closed with a stopper 7c, the other end is fixed to the side of the base 1, and a screw type stopper 7a and its screw base 7b are provided.
has. One end of the pipe 7 (inner back side) is fitted with a metal fitting 7d
It is fixed lower than the other end. The diameter of the hole 8 is selected as an orifice most suitable for dripping silicone oil onto the back surface of the belt 3, for example.
The reason why the pipe 7 does not span the entire width of the belt 3 and the holes 8 are concentrated in the approximate center of the belt 3 is that in actual use, it is enough to reduce the friction in the approximate center of the belt 3. That's why.

On the other hand, an oil tank 9 is removably connected to the other end of the pipe 7. The oil tank 9 is made of, for example, a synthetic resin molded body, and has a tapered tube 10 to be inserted into the pipe 7 and an oil filler port 11, and is preferably provided with a handle 12 and a lid 13. This oil tank 9
may be fixed by inserting a tapered tube 10 into the pipe 7, but in case it topples over and spills oil, a suitable pedestal 15 is provided on the side of the stand 1. Further, if necessary, a rubber hose or the like may be connected to the outer end of the pipe 7, and the hose may be led to a distant location and connected to the oil tank 9 at that location. 16 is a handrail, and 17 is an operation switch box.

Note that the length of the pipe 7 may be the entire length of the width of the belt 3, and the number and location of the pipes to be installed are not limited and are arbitrary.

To explain the operation of the above embodiment, the electric motor 5 is driven to rotate the roller 4, and the belt 3 is rotated.
When the pipe 7 rotates, the stopper 7a of the pipe 7 is removed and oil is injected into the inside using an oil pitcher, or an oil tank 9 or the like is connected to the outer end of the pipe 7. The oil that has flowed into the pipe 7 drips onto the back surface of the belt 3 through the hole 8, and
Adheres to the back side. Therefore, when the belt 3 rotates and reaches the upper surface of the flat portion 2, the oil spreads between the belt 3 and the flat surface in the form of a film and lubricates both. Therefore, as long as the belt 3 continues to rotate, oil is always present between the belt 3 and the flat portion 2, allowing the belt 3 to move smoothly.

Effects of the invention According to the invention described above, an oil film is formed between the belt and the platform having a flat part that movably supports the belt to reduce the friction between the two. You can train to run or walk on a belt supported by a stationary platform, and you can develop the same feeling as running or walking on the ground or floor. This prevents damage from wear and tear on both parts, which extends the service life of the belt, and also allows the belt to maintain a stable predetermined speed without decreasing the predetermined speed that should be set for the belt. Effective running training or rehabilitation can be done. Furthermore, the amount of oil can be set depending on the length and inner diameter of the pipe, and in addition, by setting the diameter of the hole where the oil comes out, there is the convenience of not having to refuel for a certain period of time. play.
