Abstract

An object of the present invention is to improve the muscle strength enhancing effect of a leg and a waist by making it possible to perform a stepping exercise equivalent to a movement up a staircase. A tread plate is slidably mounted one by one on each of a pair of guide rails installed in parallel in an inclined state, and a cylinder is connected to each tread plate one by one via a link mechanism. The cylinder chambers communicate with each other through a distribution pipe so that the hydraulic oil can pass back and forth. When one of the treads is pushed down along the guide rail, the shaft of one cylinder connected to the treadle is lowered, and the hydraulic oil in the cylinder chamber flows into the cylinder chamber of the other cylinder and the other shaft is raised. And since the other step board connected to this goes up, the stepping motion equivalent to the operation | movement which goes up stairs can be performed. [Selection] Figure 1

Description

  [Technical Field] The present invention relates to a stepping health device that enhances muscle strength of the legs and legs by a stepping motion that pushes up the body.

  Various types of foot health devices have been proposed in the past. Typical examples thereof are as shown in Patent Documents 1 and 2 below. In Patent Document 1, left and right footboards alternately move up and down in the vertical direction. In Patent Document 2, the left and right footboards rotate about their tips, so that the heel portions of the left and right footboards rise and fall alternately.

Japanese Utility Model Publication No. 63-50363 JP 2000-93552 A

Since the above conventional foot-operating health appliances only move the foot up and down, the movement of the foot is monotonous and easy to get tired, and the exercise strength is small and the effect of strengthening the muscle strength of the legs and hips is poor.
An object of the present invention is to make it difficult to get tired and to improve the muscle strength enhancing effect of the legs and hips by making it possible to perform a stepping motion equivalent to a movement up the stairs.

The present invention comprises a pair of guide rails installed in parallel in an inclined state,
A treadle slidably mounted on each of the guide rails,
Having one cylinder connected to each of the treads;
The treads and the shafts of the cylinders are connected by a link mechanism,
The cylinder chambers of the cylinders are communicated by a distribution pipe so that the hydraulic oil can flow back and forth.
When one of the treads is pushed down along the guide rail, the shaft of one of the cylinders connected to the tread is lowered, and the hydraulic oil in the cylinder chamber flows into the cylinder chamber of the other cylinder and the other shaft is raised. And the other footboard connected to the footboard rises.

  As a specific configuration of the link mechanism, for example, a swing bar provided so as to be rotatable about a central portion and swingable like a seesaw, and pivotally attached to both ends of the swing bar one by one. A connecting rod can be employed. One end of each connecting rod is pivotally attached to the end of the swing bar, and the other end is pivotally attached to each tread. The tip end portions of the shafts of the cylinders are pivotally mounted on both sides of the swing bar.

  An adjustment valve can be provided in the distribution pipe so that the distribution resistance of the hydraulic oil can be adjusted. Thereby, it becomes possible to adjust the descending speed and the resistance force when the treadle is depressed.

In the foot health device of the present invention, when the weight is placed on the right foot board with the right foot, the foot foot slides obliquely down to a predetermined position, and at the same time, the left foot board slides up to the predetermined position. Next, when the left foot is stepped in half and the weight is placed on the left tread, it slides down to a predetermined position, and at the same time, the right tread slides up to a predetermined position. By repeating this, it is possible to perform the stepping motion equivalent to going up the stairs, and can continue the stepping motion without getting tired as compared with a conventional device in which the footboard simply moves up and down. When stepping on a foot, stepping half a step, gaining weight, and supporting the weight, the muscles of the legs and hips can be used, resulting in a great strength enhancement effect.
Further, the foot health device of the present invention can be manufactured at low cost without requiring any power such as a motor because the tread plate is moved up and down by weight shift.

It is a perspective view of the stepping health device of an example. It is a bottom view of an inclined board.

An embodiment of the present invention will be described based on the drawings.
FIG. 1 is a perspective view of a foot health device according to the embodiment, and FIG. 2 is a bottom view of the inclined plate 1a.

  1 and 2, a frame 1 is formed by assembling steel materials by welding. The frame 1 includes an inclined plate 1a provided in an inclined manner and a handrail 1b provided with a round pipe bent in an inverted U shape vertically. In addition, wheels 2 for traveling convenience are attached to the left and right sides of the frame 1.

  As shown in FIG. 1, a pair of guide rails 5 and 5 are welded and fixed in parallel to the left and right ends of the upper surface of the inclined plate 1a. The guide rails 5 and 5 are square pipes, and the inclination angle is preferably 45 to 50 °. A slit 5 a is provided on the inner surface of the guide rails 5 and 5.

  A tread board 3 is slidably attached to each of the guide rails 5 and 5. The footboards 3 and 3 have slide fittings 4 on the outside. The slide fitting 4 has a bearing 4a, and thereby slides in the guide rail 5 with a small resistance. The slide fitting 4 on the inner side of the guide rail and the outer tread plate 3 are connected and integrated by a rod-like connecting portion that penetrates the slit 5a.

  As shown in FIG. 2, a swing bar 6 that is a link mechanism, connecting rods 8 and 8, and two cylinders 9 and 9 are attached to the back surface of the inclined plate 1 a. The swing bar 6 is pivotally attached to the inclined plate 1a by a shaft 7 at the center, and can swing like a seesaw. The ends of the connecting rod 8 are pivotally attached to both ends of the swing bar 6, and the other ends of the connecting rods 8 and 8 are pivotally attached to the connecting portion between the tread plate 3 and the slide fitting 4. Passes through the slits 16 and 16 provided near both ends of the inclined plate 1a.

  The lower portions of the two cylinders 9 are pivotally attached to the inclined plate 1 a, and the tip portions of the respective shafts 9 a are pivotally attached to both sides of the shaft 7 of the swing bar 6. A spring 10 is provided around the shaft 9a to urge the swing bar 6 upward.

The lower portions of the cylinder chambers of both cylinders 9 and 9 are connected by a distribution pipe 11 so that hydraulic oil can go back and forth between them. In addition, a circulation pipe 14 is provided in the upper part of the cylinder chamber to allow air and oil leaking from the upper part of the cylinder to flow through each other.
Thereby, the raising / lowering speeds of the left and right footboards 3, 3 are the same, and the raising / lowering width is also kept the same from side to side.

In FIG. 1, when the weight is placed on the left tread board 3 (right side in FIG. 2), the left tread board 3 descends obliquely along the guide rail 5. By this lowering, the left side of the swing bar 6 is pushed down, the shaft 9a of the left cylinder 9 is pushed down, and the hydraulic oil in the cylinder chamber is pressed into the cylinder chamber of the right cylinder 9, whereby the shaft 9a of the right cylinder 9 is pushed. The spring 10 is pushed up, and the spring 10 is extended and the right side of the swing bar 6 is pushed up. As a result, the right tread 3 rises obliquely along the guide rail 5.
Thereafter, when the weight is placed on the right tread 3, the right tread 3 is lowered obliquely along the guide rail 5, and at the same time, the left tread 3 is raised obliquely along the guide rail 5.

  The distribution pipe 11 is provided with an adjustment valve 12 that adjusts the distribution resistance of the hydraulic oil. The adjustment valve 12 is connected to an adjustment lever 13 (FIG. 1) provided on the handrail 1 b by a wire 15 and can be adjusted by operating the adjustment lever 13. That is, when the adjustment valve 12 is opened by the adjustment lever 13, the flow rate of the hydraulic oil increases and the treading plate 3 moves up and down. .

The above-described example is merely an example of an embodiment of the present invention, and this example can be variously modified within the scope described in the claims of the utility model registration.
For example, the frame may have any shape as long as two guide rails can be fixed in parallel in an inclined state and the swing bar can be pivotally attached. The guide rail is not limited to a square pipe, and may have any cross-sectional shape as long as the treadle can be slidably mounted.
Further, the frame, the inclined plate, the handrail, the tread plate, the guide rail, the link mechanism, and the like are not limited to metal and may be made of plastic.
