[0003] [Patent Document 1] Patent No. 6198928 [Patent Document 2] Patent No. 5236576 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional training machines such as that described in Patent Document 1 enable advanced users who are familiar with the training machines to exercise any desired muscle, for example, training the upper limbs, shoulder muscles, and trunk.

[0005] However, the training machines cannot provide effective training for beginners, such as elderly users who need body repair or users who are not very physically strong.

[0006] In view of the above circumstances, an object of the present invention is to enable even beginners to train their upper limbs, shoulder muscles and trunk without being conscious of it. [Means for solving the problem]

[0007] Therefore, one aspect of the present invention is a training machine having a handle that can be rotated vertically and horizontally by operation of a user, and a seat on which the user sits and which can rotate in conjunction with the horizontal rotation of the handle.

[0008] In one aspect of the present invention, the training machine further includes a seat linkage mechanism that is capable of rotating the seat in conjunction with the horizontal rotation.

[0009] In one aspect of the present invention, in the training machine, the seat linkage mechanism includes a handle rotation section to which the handle is attached, a handle shaft to whose upper end the handle rotation section is rotatably connected in both vertical and horizontal directions so as to rotate the seat in response to the horizontal rotation, a linkage plate fixed to the handle shaft, a pin that can be engaged with the linkage plate, and an operating lever supported by the handle rotation section for engaging or disengaging the pin with respect to the linkage plate.

[0010] In one aspect of the present invention, the training machine further comprises a seat shaft that is erected so as to be rotatable in conjunction with the horizontal rotation and that horizontally supports the seat, and a load application device that applies a braking torque to the rotation of the seat shaft. Effect of the Invention

[0011] According to the present invention, even a beginner can train the upper limbs, shoulder muscles and trunk without being aware of it. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0014] The training machine 1 of this embodiment shown in Figure 1 has a handle 2 that can be rotated vertically and horizontally by operation of the user, a seat 3 on which the user sits, and a seat linkage mechanism 4 that enables the seat 3 to rotate in conjunction with the horizontal rotation of the handle 2.

[0015] The handle 2 is attached to a handle rotating portion 41 of the seat interlocking mechanism 4 in an upper main body frame 7 supported horizontally by a main body frame 6 erected on a base frame 5 on the floor surface as shown in Fig. 1-4, and has a handle socket 20. A roughly L-shaped right handle 21 is attached to the right end of the handle socket 20. A roughly L-shaped left handle 22 is attached to the left end of the handle socket 20. The orientations of the right handle 21 and the left handle 22 can be adjusted around the axis of the handle socket 20.

[0016] The seat 3 is supported so as to be rotatable in the horizontal direction on the upper end of a seat shaft 31 erected by a support frame 51 in a base frame 5 shown in Fig. 1-4. The seat shaft 31 is rotatable in the horizontal direction in association with the horizontal rotation of a handle shaft 42 to which a handle rotation part 41 of the seat interlocking mechanism 4 shown in Fig. 6 is attached.

[0017] 1-4, a step frame 33 having a step 32 on which the user's feet can be placed is supported near the upper end of the seat shaft 31 directly below the seat 3. Furthermore, a seat shaft gear 34 is attached near the lower end of the seat shaft 31 to which an interlocking chain 47 is attached from the handle shaft gear 43 in Fig. 6 via an upper end relay gear 61 and a lower end relay gear 62 in Figs. 2, 4 and 5. Furthermore, a brake gear 35 is attached to the seat shaft 31 to which a brake chain 84 of the load application device 8 in Fig. 1-4 is attached.

[0018] A braking torque is applied as a load from a load applying device 8 to rotate the seat shaft 31. As the load applying device 8, for example, the load applying device disclosed in Patent Document 2 is applied.

[0019] 1 and 3, the load application device 8 includes a control monitor 81, an electromagnetic brake unit 82, and a load transmission mechanism 83. The control monitor 81 is disposed above the main body frame 6 of the training machine 1, and the magnetic brake characteristics are set as the load by the user's operation. The electromagnetic brake unit 82 generates a braking torque for rotating the seat shaft 31 based on the magnetic brake characteristics. The load transmission mechanism 83 transmits the braking torque to the braking gear 35 of the seat shaft 31 via a braking chain 84. The electromagnetic brake unit 82, the load transmission mechanism 83, the braking chain 84, and the braking gear 35 are housed in a casing 85.

[0020] As shown in Fig. 6, the seat interlocking mechanism 4 includes a handle rotating part 41, a handle shaft 42, a handle shaft gear 43, an interlocking plate 44, a pin 45, an operating lever 46, and an interlocking chain 47. The handle socket 20 of the handle 2 is attached to the upper surface of the handle rotating part 41. The handle shaft 42 is rotatably erected by a bearing support member 421 at one end side of the main body upper frame 7 near the seat 3. The handle rotating part 41 is connected to the upper end of the handle shaft 42 so as to be rotatable in the vertical direction via a rotating shaft 411 and in the horizontal direction via a bearing 412. Meanwhile, the handle shaft gear 43, to which the interlocking chain 47 is hung, is attached near the lower end of the handle shaft 42. The interlocking plate 44 is fixed to a position between the handle rotating part 41 and the handle shaft gear 43 on the handle shaft 42. The pin 45 is inserted into a guide sleeve 481 arranged vertically on a bracket 48 fixed near the upper end of the handle rotating portion 41, and can be engaged with an engagement hole 441 near one end of the interlocking plate 44. The operating lever 46 is rotatably attached to the bracket 48, and engages or releases the pin 45 with the engagement hole 441 of the interlocking plate 44 via a connecting member 49. The interlocking chain 47 is arranged along the upper main body frame 7, the upper main body frame 7 and the base frame 5, as shown in FIG. 1-5, and is hung on the handle shaft gear 43, the upper end relay gear 61, the lower end relay gear 62 and the brake gear 35.

[0021] An example of the operation of the training machine 1 will be described with reference to FIGS. 1-6.

[0022] When training is performed by linking the seat 3 with the handlebars 2, the operating lever 46 is set vertically to the interlocking plate 44 by the bracket 48 as shown in FIG. 6(a). At this time, the connecting member 49 connected to the operating lever 46 pushes down the pin 45. The pin 45 is guided vertically by the guide sleeve 481 and descends toward the interlocking plate 44. When the stopper 451 of the pin 45 abuts against the interlocking plate 44, the pin 45 is inserted into the locking hole 441 of the interlocking plate 44. As a result, the pin 45 is locked to the interlocking plate 44, and the handle shaft 42 becomes rotatable in accordance with the horizontal rotation of the handle rotating part 41, so that the seat 3 can be linked to the handlebars 2.

[0023] When a user sitting on the seat 3 places both feet on the step 32 and rotates the right handle 21 and the left handle 22 horizontally or horizontally and vertically, the handle shaft 42 rotates due to the rotational force of the handle rotating part 41 via the interlocking plate 44 with which the pin 45 is engaged. The rotation of the handle shaft 42 is transmitted to the seat shaft 31 via the interlocking chain 47 that is hung on the handle shaft gear 43, the upper end relay gear 61, the lower end relay gear 62 and the seat shaft gear 34 in FIG. 2-6, and the seat 3 rotates in conjunction with the horizontal rotation of the handle 2. Since a load is applied to the handle shaft 42 and the seat shaft 31 in advance by the user operating the control monitor 81, the user can train his / her upper limbs, shoulders and trunk by rotating the handle 2 and the seat 3 as described above.

[0024] When training is performed without linking the seat 3 with the handle 2, the operating lever 46 is lowered toward the interlocking plate 44 as shown in Fig. 6(b). At this time, the pin 45 is pulled out of the interlocking hole 441 of the interlocking plate 44 by the connecting member 49 connected to the operating lever 46, the pin 45 is released from the interlocking plate 44, and the seat 3 is no longer linked with the handle 2. Then, when the handle 2 (right handle 21 and left handle 22) is rotated horizontally, the handle rotating part 41 at the upper end of the handle shaft 42 rotates freely due to the bearing 412, so that only the handle 2 rotates. This allows the user to stretch their upper limbs, shoulders, and trunk.

[0025] According to the training machine 1 described above, the user can push and pull the right and left handles 21 and 22 held by the user back and forth while moving them up and down, which rotates the seat 3 horizontally, allowing the user to perform movements similar to paddling a canoe. This allows the user to train the upper limbs, shoulders, and trunk. In addition, the user's shoulders move in an elliptical orbit without being aware of it, allowing training of the deep muscles of the shoulders. Furthermore, by setting the load using the load application device 8, it is possible to reproduce the load of body repair, which is similar to the movement of paddling a canoe or the resistance of water, thereby improving the effect of stretching for elderly users and users with low physical strength.
