Description

[Detailed description of the invention] <Technical field> This invention relates to an invention for geta that is convenient for training leg strength and maintaining health.

<Prior Art> Conventionally, in order to improve leg strength, people have worn heavier clogs, shoes, etc. to apply weight to the feet and strengthen muscle strength. The iron geta and iron shoes used for this purpose had a fixed weight, and it was not possible to adjust the weight according to one's physical condition or the progress of training. Furthermore, such devices are inconvenient to use in daily life, and no consideration has been given to health functions through partial movement of toes and the like.

<Purpose of the invention> In consideration of the above points, the purpose of this invention is to provide health-promoting geta that can be worn in daily life, whose weight can be adjusted, and which allows for pressing movements of the toes. It is.

<Structure of the invention> a Summary The gist of the structure of this invention is that in the base part 1 of the geta having a thong, the stepped part 5 formed at the front part has a pressing plate 15, and a cylinder horizontally installed on the lower surface. shaped tooth part 1
1, the pressing plate 15 has the front cord 3 fixed thereto, is urged upward by a leaf spring bent upward, and is screwed onto the base part with an elevation angle in the front direction. , health-promoting clogs in which a weight 25 is removably fitted into a cylindrical toothed part 11.

<Example> Hereinafter, an example of this invention will be described in detail based on the drawings.

As shown in FIGS. 1 to 4, reference numeral 1 denotes a platform having a stepped portion 5 at the front and a cylindrical tooth portion 11 horizontally disposed on the lower surface. Further, in the stand part 1, an escape hole 6 and a hole 7 are formed in the stepped part 5, and a protective wall 23b is protruded from a predetermined position on the lower surface of the stepped part 5. Also, paragraph section 5
A recess 10 is formed in which one end of a leaf spring 20 (to be described later) is buried when descending into a step, and a required number of holes 9 are bored in this recess 10 in alignment with the holes 21 of the leaf spring 20. Further, two lateral holes 8 are bored in the rear half part to form the base part 1. In addition, there is a lock screw 24 in hole 7.
is loosely fitted.

The toothed portion 11 has a square hole passing through the inside thereof from side to side to form a cylindrical portion 12, and a fitting portion 1 is formed on the bottom surface of the cylindrical portion 12.
A buffer member 14 is fixed via 3. still,
The buffer member 14 is not limited to the above-mentioned fixing method; a set screw may be used, or the buffer member 14a held between the metal fittings 13a may be fixed using a set screw as shown in FIG. .

The pressing plate 15 has the same outer shape as the outer periphery of the stepped portion 5, and is formed to have a thickness equivalent to the stepped height. Further, a front hole 16 for fixing the front cord 3 is formed in the pressing plate 15, and a screw hole 19 is provided at a predetermined position. A recess 18 is formed in the upper surface in which the other end of the leaf spring 20 is buried.
A required number of holes 17 are bored in 8 to match the holes 22 of the leaf spring 20. Further, when the pressing plate 15 is at its maximum elevation angle, an L-shaped stopper member 23 is loosely inserted into the hole 6 and has a length such that its bent portion 23a comes into contact with the lower surface of the stepped portion 5 at a predetermined position on the lower surface of the pressing plate 15. drilled in position.

Here, the material for forming the base portion 1 and the press plate 15 is not limited to metal materials such as cast iron and aluminum alloy, but may be synthetic resin materials. Further, the buffer member 14 is made of a rubber material or a soft synthetic resin material.

The leaf spring 20 is a band-shaped spring material having an inverted angle shape and has a required number of holes 21 and 22 formed therein. And press plate 15
and the base portion 1 are connected to each other by placing leaf springs 20 in the respective recesses 18 and 10. More specifically, the pressing plate 15 is given an elevation angle in the front direction and is biased upward by the inverted C-shaped leaf spring 20.
The holes 9, 22, and 17 are riveted to form a hinge.

An overlay 4 is attached to the upper surfaces of the base part 1 and the pressing plate 15, and the thong 2 is fixed to the side hole 8 and the front thong 3 is fixed to the front hole 16.

The weight 25 consists of a weight case 26, a weight member 32, and other parts, and one foot is formed by four sets.

The weight case 26 is a horizontally elongated box-like member that is loosely fitted into the cylindrical portion 12 of the tooth portion 11 and has an open top surface and is slightly shorter than the length of the cylindrical portion 12 .

One longitudinal end surface of the weight case 26 has a flange 27, and the other end surface has a screw hole 28 formed therein. The lid 29 is sized to substantially cover the end surface of the cylindrical portion 12, and has a hole in the center through which a set screw 30 passes.

Furthermore, the weight member 32 that can be accommodated in the weight case 26 is
It is made of lead, etc., which has a high specific gravity, and can be given any shape such as a plate, rod, or sphere. And this weight member 32
A suppressing member 31 for suppressing rattling within the weight case 26 is also disposed within the weight case 26. A suitable material for this restraining member 31 is a sponge-like elastic body or an elastic metal plate.

Note that this invention is not limited to the above-mentioned explanation and illustrations, and its embodiments can be modified within the scope of the technical idea of this invention.

<Usage Mode> Next, the usage mode will be explained. When the base portion 1 and the pressing plate 15 of the embodiment are made of aluminum alloy, the weight of the main body is approximately 1 kg (one foot).

To further increase the weight, weight members 32 of appropriate weights are housed in the four weight cases 26. Then, a restraining member 31 is arranged on the upper part, and each is fitted into the cylindrical part 12. At this time, the weight case 26 is in a fitted state with the flange 27 abutting one end of the cylindrical portion 12 and the screw hole 28 facing the other end.
When a set screw 30 is screwed into this screw hole 28 through a lid 29, the lid 29 comes into pressure contact with the end surface of the cylindrical portion 12, and the weight case 26 is fixed within the cylindrical portion 12.

When wearing such geta, not only the above-mentioned weight load is applied to the feet, but also the pressure plate 15, which is biased and has an elevation angle forward, is pressed with the toes while walking. will be held.

Further, this pressing plate 15 can be pressed repeatedly by moving only the toes even when not walking.

The stopper member 23 defines the maximum elevation angle of the pressing plate 15, and also receives the weight that is applied to the front side of the platform 1 which is away from the ground when the foot is raised. The protection chamber 23b protects the stopper member 23 from coming into direct contact with a protruding object on the ground.

Further, when the lock screw 24 is screwed into the screw hole 19, the press plate 15 comes into contact with the stepped portion 5, and the elevation angle of the press plate 15 becomes zero, and the rotation is fixed. (5th
(See figure) <Effect of the invention> As described above, the health-promoting geta according to this invention is hinged to the stepped part formed in the front part of the base with a biased forward angle of elevation. The clogs have a pressing plate, the front cord is fixed to the pressing plate, and a weight is removably fitted into the cylindrical teeth, so the weight of the geta can be adjusted for daily life and sports.
You can freely select the appropriate weight according to your physical strength and training progress. In addition, when walking, the toes press against the pressure plate against the elasticity of the leaf spring, which strengthens the leg muscles, and actively exercises the toes to improve blood circulation and maintain health. can be achieved.

This toe exercise can be performed even when not walking, and has excellent health effects.
