[Industrial applications]

 In this device, a person enters a sphere, and while standing upright in the diametrical direction, grasps the inner handle with both hands, fixes both feet, and changes the center of gravity of the body, rolling the sphere in the desired direction. The present invention relates to a switch for exercising.

[0002]

[Prior Art]

 In general, a gyroscope is a kind of gymnastics used when training a pilot or other aircraft occupant in order to develop a strong physical body that can counter the situation in which the body may roll. Although it is a device, it is rarely used as a play device for school children.

Conventionally, as shown in FIG. 4, this diverter bends a plurality of metal pipes or rods 20 made of steel or the like into a predetermined curvature and has a cage-shaped diameter with a predetermined interval. A sphere 21 having a size of about 2 meters was formed, and the two pole portions 22 and 23 were converged and connected, and a door 24 was provided on a part of the spherical surface for a person to enter and leave.

Therefore, the trainee opens the door 24 of the sphere 21, enters the inside of the sphere 21, closes the door, and, as shown in FIG. 5, holds the handles 25, 25 fixed to the inner surface of one pole 22 of the sphere 21 with both hands. To fix the trainee 27 by inserting both legs into the grips 26, 26 that are the shackles fixed to the inner surface of the other pole 23 and change the center of gravity position by moving the body of the trainee 27. This causes the sphere 21 to roll on the plane 28 in the desired direction.

[Problems to be solved by the device]

 However, since the conventional operation device is in the state of being completed as a sphere, it requires a considerable space for its storage location, and it is difficult to secure the storage location.

Further, since the conventional operation device is made of metal, it is heavy in weight, and therefore it is difficult to move it without a considerable amount of exercise. However, if it is made lighter, a predetermined strength cannot be maintained. Since it is heavy in weight, if it is left unattended, for example, on the playing field, there is a risk that children, etc. who cannot handle the gyro will roll and play, become injured or injured.

Further, in the conventional operation device, each sphere is made up of dedicated parts, and since each sphere is manufactured individually by welding or the like, it is not possible to standardize the parts. , Productivity is extremely poor. Moreover, if a part of the switch is damaged by use, it cannot be used during the repair period.

Therefore, the present invention has been made for the purpose of improving the storage property and weight of the switching device and improving the productivity.

[0009]

[Means for Solving the Problems]

 The operation device according to the present invention is characterized in that a spherical body is formed by a curved outer shell part formed by dividing a spherical surface into a plurality of parts.

The outer shell part is formed of ribs having an appropriate gap, is composed of a curved member of a substantially equilateral triangle formed by dividing a spherical surface into 20 equal parts, and is integrally formed of a lightweight material. In addition, a base rib made of resin and two side ribs form a curved equilateral triangle, and a central rib and a center rib made of resin that converge together with the side rib from the center of the bottom rib It is characterized in that it is composed of a resin-made intermediate rib 8 connecting between the side ribs.

[0011]

[Action]

 Since the gyroscope is divided into two parts, the storability is improved by dividing the parts, and the parts can be made common, and the parts are made of a lightweight material such as resin, which makes them lighter.

[0012]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall perspective view of the operating device according to the present invention. The operating device 1 made of a sphere is formed by an outer shell component 2 obtained by dividing a spherical surface into 20 equal parts, and the outer shell component 2 is connected in a mosaic shape. To form a spherical surface. Then, on the spherical surface, a parallel line rib 3 composed of a circle that spreads from both poles of the sphere toward the equator and has the same radius, and a meridian rib 4 composed of a circle whose radius gradually decreases from the equator to both poles. It is a cage-shaped sphere composed of and.

Since the outer shell component 2 is a spherical surface divided into 20 equal parts, it is a substantially equilateral triangle and is formed of a resin such as FR P. As shown in FIG. 2, the bottom rib 5 and the two side ribs 6, 6 form an equilateral triangle, one end of which is connected to the center of the bottom rib 5 and the upper end of which converges with the side ribs 6, 6. A central rib 7 integrally connected with each other, and a plurality of intermediate ribs 8 parallel to the bottom rib 5 that connect the two side ribs 6 and 6 and the central rib 7 are provided at appropriate intervals to form a gap 9. It is formed like a cage.

The bottom rib 5 and the intermediate rib 7 form the latitude line 3, and the side rib 6 and the center rib 7 form the meridian rib 4. However, the side rib 6 is slanted at the equator of the sphere. Appears in the line. The bottom rib 5 and the side ribs 6 and 6 are provided with appropriate numbers of insertion holes 10 for connecting the adjacent outer shell components 2.

The structure for connecting the adjacent bottom ribs 5 and 5 and the side ribs 6 and 6 is as follows. In addition to inserting a bolt into the bolt insertion hole 10 and tightening it with a nut, as shown in FIG. To integrally form a protrusion 12 having a head 11 on one of the bottom rib 5 or the side rib 6 to be connected and press-fit the head 11 to the other bottom rib 5 or the side rib 6. The hole 13 may be provided in advance. Alternatively, as shown in FIG. 3B, a diametrical hole is formed at the end of the protrusion 12 that does not form the head 11, and the pin 13 is inserted into the hole to stop the hole. May be.

On the back surface (inner side of the sphere) of the outer shell component 2, a handle for gripping with both hands and a shackle for inserting and fixing both feet are provided. As shown in FIG. 2, this is a U-shaped metal or resin handle 15 which is connected to the side ribs 6 across the central rib 7. The handle 15 allows the insertion of the toes, and Form it so that it can be held by hand. Since it is sufficient that at least four handles 15 are provided, the handles 15 may be provided on the four outer shell components 2, but they may be formed commonly to all the outer shell components 2.

Further, when a sphere is formed by 20 outer shell parts 2, it is necessary to form an entrance / exit for a person, which makes one outer shell part 2 removable and fixable from a spherical surface. Alternatively, the structure may be freely selected by connecting it with a hinge so that it can be opened and closed, or by forming a circular hole in the outer shell component 2 itself. Further, although the outer shell component 2 is made of resin, it may be made of light metal such as aluminum.

Therefore, after forming a sphere with 20 outer shell parts 2 and performing a maneuvering motion, each outer shell part 2 can be removed to disassemble the spheres, and these can be stacked and stored. Since the outer shell part 2 is made of resin, it is lightweight and convenient to carry, and because it is lightweight, it requires only a small amount of momentum for rolling the tumbler. Further, if one outer shell part 2 is damaged or broken, it can be easily replaced with the outer shell part 2 stored as a spare, which is convenient.

[0019]

[Effect of the device]

 According to the present invention described above, the operation device is configured to be dividable, so that it has excellent storage efficiency, and because it is divided, productivity is good, and part of it is damaged or damaged. However, in order to maintain a perfect sphere, it can be immediately replaced with a spare outer shell component, and because it is made of a lightweight material such as resin, it is lightweight, and because it is lightweight, it excels in rolling performance and momentum. It has the effect of reducing it.
