Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a training device, and more particularly to a training device that utilizes the buoyancy of a float floating on the water surface.

The term "training" as used herein means

2. Description of the Related Art As a conventional training device, although not shown in the drawings, there has been, for example, the following device using a weight made of metal.

This device is installed on a floor, and a metal weight is supported by a device body so as to be vertically movable. The user grasps the handle portion, which is indirectly connected to the weight, with a hand and pulls the handle portion. As a result, the weight is pulled up, and at this time, the arm having the handle portion is loaded.

When the hand holding the handle is released or the hand holding the handle is released, the weight is lowered by its own weight and returns to its original position. By repeating such an operation, the user can train his arm.

[0006]

However, the conventional training apparatus has the following drawbacks. That is, since the apparatus main body must firmly hold the weight made of metal, it is necessary to form the body with a thick and heavy body. Therefore, the weight of the entire device including the weight is considerably heavy, and a very difficult work is forced, for example, when the device is assembled or moved.

Further, during the use of the above training apparatus, a monotonous and cold mechanical sound is produced by the rubbing of metals with each other, which causes the user to feel mental stress and reduce his willingness to train. It also caused me to

[Object of the Invention] The present invention has been made in view of the above circumstances, and an object of the present invention is to reduce the weight of the entire apparatus, and to easily perform it when, for example, assembling or moving the apparatus. In particular, the present invention is to provide a training device having an active and bright image, which can enhance the user's motivation for training.

[0009]

A training device of the present invention is provided with a float floated on a pool, an operating part such as a handle part which is reciprocally movable on a straight line or a curved line, the float and the operating part. And a force transmission unit that connects the two units to each other so that force can be transmitted to each other, and the user applies a force to the operation unit to move the operation unit forward, whereby a part or the whole of the float floated in the pool. Submerged in water against buoyancy, by loosening the force on the operating portion, the float floats according to the buoyancy,
In conjunction with this, the operation section is moved back to return to the original position.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The above-mentioned "float" means an air bag or hollow container made of rubber or synthetic resin filled with gas (air, nitrogen, etc.), a synthetic resin foam such as foamed styrene, or a piece of wood. It refers to anything that has the property of buoyancy acting to float by sinking.

The shape of the float is spherical, cylindrical,
Plate, egg-shaped, conical, inverted conical, rectangular parallelepiped, polygonal pyramid such as triangular pyramid or quadrangular pyramid, gourd-shaped, polygonal columnar, bulged outward or recessed at a predetermined position For example, it may be shaped like an article such as a ship or a car, shaped like an animal, or shaped like a popular character such as a cartoon.

If the float is a cylinder extending in the vertical direction (a cylinder whose diameter is constant in the vertical direction), the volume per unit height of the float and the volume are the same in all parts. The amount of power required to sink it only increases by a certain amount, but
For example, in the case of an inverted conical shape, the volume per unit height of the float increases as the volume rises, so the force required to sink this float increases at a constant amount. Yes, it increases like a quadratic curve. Therefore, in the case of using the inverted conical float, a larger load is applied to the latter half as compared with the case of using the columnar float described above. Utilizing such a principle, it is possible to devise so that training can be performed efficiently.

That is, in a series of motions of the user until the float is completely submerged, it is easy to counter a large load at a motion that can be relatively easily performed on the structure of the body. The volume and volume of the float corresponding to can be increased. On the other hand, in an operation where it is relatively difficult to move, even a small load may not be able to cope with it, so the volume and volume of the float corresponding to that portion may be reduced.

A balloon type float with an automatic buoyancy adjusting device can also be used. That is, expansion (expansion)
It is also possible to use a float that can be reduced in size and can freely supply and exhaust air from the outside. By using this float, the float buoyancy can be adjusted, that is, the load can be adjusted without changing the float or attaching / removing the float.

[Operation] In the training apparatus of the present invention, a force is applied to the operation portion provided so as to be reciprocally movable, and the operation portion is moved forward. That is, the operating portion, for example, the handle portion is grasped by hand, or the foot is put on the pedal portion, and the operator pushes, pulls, raises, or lowers the handle portion or the pedal portion with force. This force is transmitted to the float via the force transmitting portion, and the float sinks in water against buoyancy. At this time, a load is applied to the arm gripping the handle portion or the foot applied to the pedal portion.

When the amount of force applied to the operating portion is reduced to be less than the buoyancy of the float, the float floats according to its own buoyancy, and in conjunction with this, the operating portion returns to the original position.

In the training device of the present invention, as described above, the load on the body is generated when the float sinks against the buoyancy, so it is necessary to use the conventional weight made of metal. And there is no need for a thick and heavy body to support it. Therefore, the weight of the entire apparatus can be reduced, and the apparatus can be easily assembled or moved, for example.

The degree of load on the body is proportional to the buoyancy of the float, and this buoyancy is proportional to the volume and volume of the float. For example, if the load is to be increased, the number of floats should be increased, or the volume and volume should be larger. Replace with a larger float. Conversely, if you want to reduce the load,
Either reduce the number of floats or replace with a smaller float. In the device of the present invention, since the float itself does not have a great weight, the float can be easily attached, detached and replaced as described above.

Further, during the use of the above training apparatus, a monotonous cold mechanical sound that causes a decrease in training will not be heard, and the user may feel mental stress. Absent. On the contrary, the training device of the present invention has the fun of float ups and downs as described above, and makes the user feel enjoyment and dynamism. In addition, the training device of the present invention has a lively and bright image due to the sound of waves and splashes when the float rises and falls.

Unlike swimming training, the hair does not get wet during use and the swimming cap is not required. Also, since my face does not get wet,
Especially in the case of women, there is no concern about makeup loss.

In using the training apparatus of the present invention, it does not matter whether the user can swim or not. That is, by using the device of the present invention, even a person who cannot swim can enjoy training in water.
