Description

[Detailed description of the invention] "Industrial application field" This invention relates to a light forging tool. More specifically, the present invention relates to a light forging tool that can be easily used in an automobile, as well as in a room such as an office or a home.

"Conventional technology" Many conventional training tools have been developed for use in training gyms and the like. However, training tools for training gyms often have a large weight and volume, and some are similar to complicated machines, so that hard training is usually required for users. For this reason, it was not a training tool that could be used by anyone anytime, anywhere.

Japanese Utility Model Application No. Sho 62-145050 previously proposed by the present applicant as a training tool that can improve the above points and can be easily used at any time in an office or home, for example, and can train a leg. There is a device.

"Issues to be solved by the invention" The leg exerciser proposed earlier by the present applicant is provided with two horizontal frames vertically between vertical frames erected on a base, and the upper horizontal frame The lower horizontal frame is adjustably fixed to the vertical frame, the lower horizontal frame is vertically movably engaged with the vertical frame, the upper and lower frames are connected with a flexible belt, and the rubber ball is placed between the upper and lower horizontal frames. Intervening. In this method, a movable lateral frame is used so as to be positioned near both knee joints while sitting on a chair. The leg and hip training device proposed earlier by the inventor can easily train the legs indoors, and there is a convenience that can be used while sitting on a chair or the like.

However, since the vertical frame is erected on the base, although it is simple, it occupies a considerable space. And there is the inconvenience that you cannot carry around freely. In some cases, you can train your legs, but you cannot train other muscles.

An object of the present invention is to provide a light training device capable of training limbs, abdominal muscles, waist, etc., which is portable and can be used indoors, in a passenger car, and the like.

"Means for solving the problem" The present inventor has discovered that by pressing the ball on the floor with one or both hands on the floor, the muscle can be exercised from the arm to the shoulder, from the shoulder to the chest, and from the chest to the abdomen. did. In such a muscle exercise, the same interlocking of the muscles occurs in a sitting state, a standing state on a knee, and a state in which the body is bent with the feet. Also, the leg and waist muscles are trained by pressing and moving the ball on the floor with the sole of the foot. The present invention has been made by paying attention to these, and a first invention of this invention includes a base plate having a recess at the center of the upper surface, and an elastic ball larger than the spherical diameter of the recess of the base plate. A light forging tool characterized by being fitted and held in a recess. The second invention of this invention has a base plate provided with a recess at the center of the upper surface and provided with a long groove on the left and right sides from the front to the rear as viewed from the user, and is larger than the spherical diameter of the recess of the base plate. A light forging tool characterized in that an elastic ball is fitted and held in the concave portion, and a hard ball having a larger ball diameter than a maximum width portion of the long groove is fitted in the left and right long grooves.

A third invention of the present invention is the light forging tool according to the first invention, wherein the base plate has an upper surface which rises from the near side to the rear as viewed from the user.

[Operation] In the first invention of this invention, when the elastic ball held in the concave portion at the center of the base plate is pushed by one or both palms, the elastic ball is deformed and gives resistance to the hand. Next, loosen your hand to restore the elastic ball, and repeat pressing the elastic ball with your palm again. Thereby, the arm and the abdominal muscle are trained.

In a second aspect of the invention, in addition to the first aspect, while sitting on a chair, a seat of a car, or the like, the soles of the feet are placed on the hard balls and the feet are pushed back and forth while pressing the hard balls. Then, the hard ball rolls relatively to the foot and rolls on the long groove. This will train your legs and legs.

In a third aspect of the invention, the usage of the elastic ball is similar to that of the second aspect.

When sitting on a chair, a seat of a car, or the like, putting the sole of the foot on the hard ball and pushing the foot forward, the hard ball climbs a slope from the near side of the long groove toward the rear. This provides resistance to the foot. When the foot is released from the hard ball, the hard ball rolls in the long groove, comes to the end in front of the hard ball, and stops. Here, the sole is put on the hard ball again, and the same operation is repeated. This will train your legs and legs. The same effect can be obtained by reciprocating the hard ball on the long groove while the sole of the foot is placed on the hard ball.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a preferred embodiment of the present invention. The front side of the figure is the place where the user is located.

The base plate 1 made of wood or synthetic resin is provided with a female screw 1a on the left and right sides of the back surface, and a rear leg 2 is screwed into the female screw 1a. When the base plate 1 is placed on the floor surface 3, the base plate 1 is supported by the front lower corner 1 b and the rear leg 2. As a result, the base plate 1 has a surface that rises at an angle っ て from the front side to the rear side with respect to the floor surface 3. When the base plate 1 is a flat plate, the angle 間 の between the back surface of the base plate 1 and the floor surface 3 is suitably 10 to 30 degrees.

A circular recess 4 is provided at the center of the surface of the base plate 1. This circular recess 4 may be a through hole. On the left and right sides of the circular concave portion 4 of the base plate 1, long grooves 6, 6 are provided from the near side to the rear.
At both ends of each long groove 6, there are circular portions 6a and 6b which are enlarged from an intermediate portion of the long groove 6. The long groove 6 may be a long hole.
An elastic ball 7 such as a rubber ball or a vinyl ball is fitted and held in the circular concave portion 4 at the center of the base plate 1. The ball diameter of the elastic ball 7 is larger than the diameter of the circular recess 4, and the elastic ball 7 is supported on the periphery of the circular recess 4. In order to hold the elastic ball 7 so as not to separate from the base plate 1, the elastic ball 7 is housed in a bag-like net 8, and the opening of the net 8 passes through a through-hole, not shown, of the circular concave portion 4. The elastic ball 7 is locked on the back surface of the circular recess 1 so as not to come off from the circular recess 4. The elongated groove 6 has an enlarged circular portion 6
A hard ball 9 having a ball diameter larger than the diameters of a and 6b, for example, a ceramic ball is fitted.

In the above example, the diameter of the circular recess 4 at the center of the base plate 1 is 60 to 70 mm, the diameter of the elastic ball 8 is 152.4 to 177.8 mm (6 ″ to 7 ″), and the diameter of the circular portion 6 a of the long groove 6. Is 30 mm hard ball 9 is 50 mm.

Next, the operation of the above configuration will be described. FIG. 2 is a side view. Place a light training device under the office desk, in front of the sitting room chair, or under the feet of the passenger or rear seat of the car. Sitting in office chairs, reception chairs, and car seats. Next, the sole B of both legs A is put on the hard ball 9 and the hard ball 9 is pushed backward while pressing the hard ball 9 with the foot, and the hard ball 9 is lifted from the circular portion 6a on the near side and the long groove 6 is lifted. Move to the middle part of
The hard ball 9 rolls in the long groove 9 and moves backward.
On the other hand, the hard ball 9 also rolls relatively to the sole B and changes the contact portion from the toe to the heel. Since the base plate 1 is raised rearward from the near side, resistance is always applied to the feet, and the muscles of the feet are trained and reach the waist.

When the foot is loosened on the way to the hard ball 9 that has moved backward, it rolls in the long groove 6 due to the inclination of the base plate 1 and falls into the circular portion 6a on the near side. Further, when the hard ball 9 is pushed to the rear circular portion 6b at the rearward movement limit, the hard ball 9 fits into the circular portion 6b. In this case, when the hard ball 9 is slightly pulled back from the sole of the foot, the hard ball 9 enters the parallel portion of the long groove 6 from the circular portion 6b, rolls and returns to the circular portion 6a on the near side. Also, when the hard ball 9 is returned, it may be returned while pressing it with the sole of the foot. Repeat such exercise. As a result, the muscles of the lower back are trained, and a partial stimulation pressure is applied to the soles of the feet to activate the cranial nerves.

In addition, since the fine ceramic is excellent in thermal conductivity, it can be heated to about 40 ° C. by immersing it in hot water for about 10 seconds. By heating the hard ball 9 in this way, the sole of the foot is warmed to the sole of the foot. It also has the effect of increasing stimulation.

FIG. 3 is a perspective view showing a state in which training is performed by a force applied to a hand. The user presses down on the elastic ball 7 with the palm of one hand or both hands C while leaning down or standing with his or her knees or standing with his legs and bending his body as shown in the figure. Repeat to relax your power. This allows the muscles to move from arm to arm, shoulder to shoulder, shoulder to chest, and chest to belly.

Medically speaking, the causes of sudden death and overwork death, which have recently become a problem in the 50s and 60s and even in the 40s, include arteriosclerosis (dissolution from bone into the intima and media of blood vessels). Heart failure is often caused by calcium deposits and blood vessels becoming stiff like a brick wall (cholesterol is not very relevant) .This arteriosclerosis is caused by insufficient exercise of the legs (they can be trained by walking or jogging. ) Is the cause.

2. Aging is not due to age, but to lack of exercise, was recently published in a medical journal in the United States by the University of Santiago Sports Medicine Research Group. If you exercise too, your blood pressure will be up 120 / down 78 (70 years old)
There is a clear statement that those who do not exercise had a blood pressure of 150/90 at 70 years of age.

Thus, the aging phenomenon occurring in the blood circulatory system can be prevented only by eliminating the lack of exercise. For this purpose, it is useful to provide a tool that can be easily used anywhere and anytime without requiring hard training unlike the light training device.

In the embodiment, the base plate 1 is inclined, but the base plate 1 may be a flat plate and may not have the rear legs. In this case, if the base plate 1 is used in a horizontal state, the reciprocating motion of the hard ball by the sole of the foot is performed while pressing the hard ball on the sole of the forward and backward feet.
