In the case of the dumbbell, it is advantageous in that the weight can be freely changed as compared with the iron array. However, as with the iron array, generally only arm training can be performed, and portability and transportability are also possible. There are problems such as inferior. In the case of the expander, there is a problem that the muscle can be loaded only when the spring in the expander is pulled, and only limited training can be performed. The vibrating rod is used to strengthen the arm muscles by vibrating the both ends of the vibrating rod by grasping and shaking the center of the rod-shaped member by hand (for example, Patent Documents). 1), this vibrating rod is inferior in portability, transportability and the like, and has a problem that only limited training can be performed. The bending rod has a structure in which gripping portions are provided at both ends of the spring body, and the arm is strengthened by gripping the gripping portion with both hands and bending the spring body at the center. Although used, this bent bar also has problems such as inferior portability and transportability, and only limited training is possible.
On the other hand, in facilities such as so-called training gyms, various types of large-sized mechanical training devices are installed (see, for example, Patent Documents 2 to 5), but in the case of these training devices, the structure is large and complicated, There is a problem that it is inferior in formability, transportability, handleability and the like.
Therefore, it is compact and excellent in portability, transportability, handling, etc., and can strengthen not only arm muscles but also various muscles such as pectoral muscles, abdominal muscles, leg muscles, etc. Currently, there is no training device that can be applied.

FIG. 1 is a schematic explanatory view showing a first embodiment of the training apparatus of the present invention. A training apparatus 1 shown in FIG. 1 includes a training mechanism unit 10 and a grip unit 100.
As shown in FIG. 2, the training mechanism unit 10 includes a first member 20 and a second member 30.

  The first member 20 is a rod-shaped hollow member having an opening at one end, and the opening is closed by a closing member 22. The closing member 22 is designed in a flat columnar shape. In this embodiment, the first member 20 is made of metal.

The second member 30 is a solid thin rod having a diameter smaller than that of the first member 20. The second member 30 has a close sliding member 32 that can slide in close contact with the inner peripheral portion of the first member 20 at one end. The rod member 35 has an outer diameter slightly smaller than the inner diameter of the first member 20. The intimate sliding member 32 corresponds to the intimate sliding portion described above, and is designed in a flat columnar shape. The intimate sliding member 32 has an outer peripheral portion that can slide the inner peripheral portion of the first member 20. A sealing member 33 is provided. The second member 30 is accommodated in the first member 20 in a state of penetrating the closing member 22. In this embodiment, the second member 30 is made of metal.
The closing member 22 is provided with a sealing member 23 at a contact portion with the outer peripheral portion of the second member 30.

A space 40 is defined by the first member 20 and the second member 30 that passes through the first member 20 and is accommodated in the first member 20, and the space 40 is filled with oil 50. ing. Since the oil 50 is sealed by the sealing member 23, the oil 50 does not leak outside through the gap between the closing member 22 and the second member 30 in the first member 20.
The space 40 is divided into a first chamber 42 located on the opposite side of the closing member 22 side and a second chamber 44 located on the closing member 22 side by the close sliding member 32 in the second member 30. Divided. The oil 50 filled in the space 40 can flow between the first chamber 42 and the second chamber 44 through the through hole 34 provided in the close sliding member 32.

The first member 20 and the second member 30 are rotatable with respect to each other.
At the end of the first member 20 opposite to the side on which the closing member 22 is provided, an attachment portion 26 of the grip portion 100 is provided. A through hole 28 is formed in the attachment portion 26. Further, an attachment portion 36 of the grip portion 100 is provided at the end of the rod-shaped member 34 opposite to the side where the second member 30 is provided. A through hole 38 is formed in the attachment portion 36.
The grip portion 100 is formed of a rod-shaped member, and one end thereof is rotatably supported by the U-shaped member 102. One of the U-shaped members 102 that pivotally support the grip portion 100 can be rotated by bolts and nuts to the through hole 28 in the mounting portion 26, and the other can be rotated to the through hole 38 in the mounting portion 36. It is pivotally supported.

  As shown in FIG. 2, the training apparatus 1 shown in FIG. 1 can move the second member 30 in the first member 20 by holding the two grip portions 100 with one hand and pulling them from both sides. At this time, the training mechanism unit 10 extends. In the training mechanism unit 10, when pulled from both sides, the second member 30 is pulled by the rod-shaped member 35 as shown in FIGS. 3 to 5 (FIG. 5 is a partially cutaway perspective view). The close-sliding member 32 provided at one end of the first member 20 moves toward the closing member 22 while closely sliding in the first member 20. At this time, the second member 30 contacts the sealing member 23 of the closing member 22 and is pulled out while sliding closely. A space 40 defined by the first member 20 and the second member 30 is divided into two by an intimate sliding member 32, and the oil 50 filled in the first chamber 42 and the second chamber 44, respectively. Flows. That is, since the volume of the second chamber 44 located on the closing member 22 side in the first member 20 is reduced by the movement of the close sliding member 32, the oil 50 filled in the second chamber 44 is also compressed. Is done. However, since the oil 50 is a liquid and has a very small volume contraction rate, the close sliding member 32 cannot move when there is no flow path serving as a drain. However, since the through-hole 34 is formed in the close sliding member 32, the oil 50 filled in the second chamber 44 flows into the first chamber 42 while passing through the through-hole 34. The through hole 34 corresponds to the above-described through hole. As a result, the close-sliding member 32 receives the flow resistance of the oil 50 flowing from the second chamber 44 through the through hole 34 and flowing into the first chamber 42, while in the first member 20, Move to. Therefore, when the grasping unit 100 is grasped with one hand and the training mechanism unit 10 is pulled, a load is applied to the muscles of both arms. As a result, strength training for both arms is performed.

  On the other hand, as shown in FIG. 2, the training device 1 can move the second member 30 within the first member 20 by holding the two gripping portions 100 with one hand and pushing in from both sides. At this time, the training mechanism unit 10 is shortened. In the training mechanism unit 10, when pushed from both sides, the second member 30 is pushed by the rod-shaped member 35 as shown in FIGS. 3 to 5 (FIG. 5 is a partially cutaway perspective view), and the second member 30. The close-sliding member 32 provided at one end of the first member 20 moves to the end side opposite to the closing member 22 side while closely sliding in the first member 20. At this time, the second member 30 is pressed into the first member 20 while being in contact with the sealing member 23 of the closing member 22 and sliding closely. The oil 50 filled in the first chamber 42 and the second chamber 44 flows. Since the volume of the first chamber 42 is reduced by the movement of the close sliding member 32, the oil 50 filled in the first chamber 42 is also compressed. However, since the oil 50 is a liquid and has a very small volume contraction rate, the close sliding member 32 cannot move when there is no flow path serving as a drain. However, since the through-hole 34 is formed in the close sliding member 32, the oil 50 filled in the first chamber 42 flows into the second chamber 44 while passing through the through-hole 34. As a result, the close-sliding member 32 receives the flow resistance of the oil 50 flowing from the first chamber 42 through the through hole 34 and flowing into the second chamber 44, while in the first member 20, Move to. Therefore, when the grasping unit 100 is grasped with one hand and the training mechanism unit 10 is pushed in, a load is applied to the muscles of both arms. As a result, strength training for both arms is performed.

  In the first embodiment, as shown in FIG. 4, notches 24 are provided on the inner peripheral portion of the end on the side of the first member 20 where the closing member 22 is provided and on the opposite side. It may be done. In this case, when the close sliding member 32 moves and reaches the region where the notch 24 is provided against the flow resistance of the oil 50, the notch 24 functions as a drain of the oil 50. Flow resistance can be reduced. For this reason, the operator can easily recognize the end of the pulling or pushing motion.

  In the first embodiment, instead of providing the through hole 34, a bypass pipe 46 as shown in FIG. The bypass pipe 46 is designed as a thin pipe, and connects the first chamber 42 and the second chamber 44 so that fluid can flow. A screw type valve 48 is provided in the flow path of the bypass pipe. The screw type valve 48 corresponds to the adjusting means described above. As shown in FIG. 7, when the screw type valve 48 is kept open, the flow path of the bypass pipe 46 is sufficiently secured, and the amount of oil 50 flowing therethrough increases. In this case, since the flow rate of the oil 50 is large, the flow resistance received by the close sliding member 32 is small. On the other hand, as shown in FIG. 8, if the screw valve 48 is closed, the flow path of the bypass pipe 46 is not sufficiently secured, and the amount of oil 50 flowing therethrough is reduced. In this case, since the flow rate of the oil 50 is small, the flow resistance received by the close sliding member 32 increases. Therefore, in this case, as the screw valve 48 is closed, the load applied to the muscle can be increased, and the load applied to the muscle can be set as desired and arbitrarily. is there.

  In the training device 1 according to the first embodiment, the first member 20 and the second member 30 in the training mechanism unit 10 are respectively rotatable, and are universal joints that connect the first member 20 and the gripping unit 100. Since a certain U-shaped member 102 is rotatably connected to the first member 20 and the gripping part 100 is rotatably connected to the U-shaped member 102, each gripping part 100 is gripped with one hand, When the training mechanism unit 10 is pulled or pushed in, it can be performed even with a rotational movement of the arm or wrist. For this reason, training can be performed on the wrist and other muscles in addition to the greater pectoral muscle and the upper arm bilateral muscle. It is also possible to preferentially train only one hand by fixing one grip 100 and pulling or pushing only the other grip 100. In addition, the gripping unit 100 can be gripped not only by hand, but also by holding it with a foot or abdomen, strengthening the leg muscles, Can also train. Moreover, training can be performed not only for the purpose of strengthening muscle strength but also for the purpose of rehabilitation.

  As shown in FIG. 9, the gripper 100 may be designed as a ring-shaped gripper 100 such as a suspension ring of a train, for example. In this case, it is convenient when the gripping unit 100 is fixed with a foot. The grip portion 100 can be designed to be detachable from the U-shaped member 102 and can be appropriately replaced depending on the purpose of use.
