Technical field

TECHNICAL FIELD [0001] The present invention relates to a training device, and more particularly to a training device suitable for at least bending and stretching the upper arm.

Background art

Conventionally, as a training device for supporting the exercise of elderly people, a training device that automatically swings an arm that flexes and extends the upper arm and the lower limb by a driving source has been proposed.

[0003] Such a conventional training apparatus is formed, for example, as shown in FIGS. That is, a seat 3 and a backrest 4 are fixed to a main body frame 1 formed by a gantry 2, and a swing drive source 5 that also has a gear motor equal force is fixed below the seat 3. A horizontal shaft 7 is rotatably supported by two bearings 6 and 6 on the rear frame 2 at the uppermost portion of the backrest 4, and arms for bending and extending the upper arm 8 are respectively attached to both ends of the horizontal shaft 7. 8 is fixed. The swing output of the swing drive source 5 is transmitted to the horizontal shaft 7 via the link mechanism 9 to swing the upper arm bending extension arm 8. The link mechanism 9 will be described in order from the swing drive source 5 toward the horizontal shaft 7. The swing plate 10 is fixed to the output shaft of the swing drive source 5 and swings. The first connecting rod 11 that connects the connecting arm 13 fixed to the intermediate horizontal shaft 1 2 rotatably supported at the lower part of 2 and the other connecting arm 14 fixed to the intermediate horizontal shaft 11 And a second connecting rod 15 that connects the connecting arm 16 fixed to the horizontal shaft 7.

[0004] When the upper arm is bent and extended, when the swing drive source 5 is turned ON, the swing plate 10 swings, and the swing is the first connecting rod 11, the connecting arm 13, the intermediate horizontal shaft 12 The connecting arm 14, the second connecting rod 15, the connecting arm 16, and the horizontal shaft 7 are sequentially transmitted to the upper arm bending / extending arm 8, and the upper arm bending / extending arm 8 is automatically swung. When the user sits on the seat 3 and grasps the gripping portion 8a of the arm flexing / extending arm 8 with both hands, the arm flexing / extending motion is automatically performed by the swinging arm flexing / arming arm 8. Disclosure of the invention

Problems to be solved by the invention

However, in the above-described conventional example, the horizontal shaft 7 serving as the swing center of the upper arm bending / extending arm 8 is lower than the upper end surface of the backrest 4 when viewed from the side, and the backrest. 4 is arranged behind the rear surface, the optimal movement trajectory of the gripping portion 8a of the arm flexion / extension arm 8 may not be provided to the user. Because the horizontal axis 7 is set at a relatively low position below the upper end surface of the backrest 4, the arm flexion and extension arm 8 rises around the horizontal axis 7 beyond the horizontal position. Because the position of the gripping portion 8a moves to the rear upper part, the position of the gripping portion 8a is too late, and the user has slid out. This is because the strength of the stretching exercise for the user does not become constant and changes from the middle when looking at the entire vertical movement trajectory of the gripping part 8a. was there.

[0006] Further, a link connecting the swing drive source 5 and the intermediate horizontal shaft 12 and a link connecting the intermediate horizontal shaft 12 and the horizontal shaft 7 are the first connecting rod 11 and the second connecting shaft, respectively. This is a four-bar link with the rod 15 in the middle of the movable part, and the connecting rods 11 and 15 swing without linear movement in the longitudinal direction. Since it is necessary to provide such a space for allowing the connecting rods 11 and 15 to swing on the back part of the backrest 4 and the lower part of the seat part 3, there is a disadvantage that the entire training apparatus becomes large. It was. Further, since the connecting arms 16, 13, and 14 are fixed to the relatively thin horizontal shaft 7 and the intermediate horizontal shaft 12, a large stress acts on each fixing portion.

[0007] The present invention has been made in view of these points, and the entire apparatus can be formed in a small size, and the user can perform an appropriate operation in which the load does not change excessively during the stroke of the stretching exercise. The purpose of the present invention is to provide a high-durability training device that can reduce the stress acting on each part of the drive train.

And by adopting such a configuration, the entire device can be made compact, allowing the user to perform an appropriate exercise in which the load does not change excessively during the stroke of the stretching exercise, The stress acting on each part of the drive system can be kept small, and durability can be enhanced.

[0009] In addition, the training device of the present invention according to claim 2 is characterized in that the arm for bending and extending the upper arm is supported by fixing a base portion to a hollow pipe loosely fitted to the horizontal shaft. By adopting such a configuration, the stress acting on the base portion of the arm for flexing and extending the upper arm can be suppressed to a very low level and durability can be increased.

[0010] Further, in the training device of the present invention according to claim 3, the connecting rod is supported by the back support itself or a sliding support member fixed in the back support so as to be movable in the longitudinal direction. And By adopting such a configuration, the connecting rod can be accommodated in the back column so as to be linearly movable.

At the position after the seat portion 22, each hollow cylindrical back column 23 is erected so as to be inclined slightly later. A backrest 24 is arranged at the front position of the back support 23, and a square tube with two square pillars 25 projecting from the back of the backrest 24 fixed to the left and right sides of the middle position of the back support 23. A cylindrical support cylinder 26 is mounted with an adjustable front and rear position. The backrest 24 is formed so as to be positioned by passing a positioning pin 27 through a positioning hole (not shown) from the support cylinder 26 toward the prism 25. The backrest 24 may be fixed to the back support 23 or the main body frame 21.

[0020] A substantially U-shaped support stay 28 that opens forward is fixed to a position higher than the upper end of the backrest 24 of the back support 23, and a horizontal shaft 29 is interposed between both ends of the support stay 28. It is horizontal. A large-diameter support pipe 30 is rotatably fitted to the horizontal shaft 29 via a bearing (not shown), and the upper arm bends and extends from both ends of the support pipe 30. The arm 31 protrudes by welding the base part toward the front. As a result, the upper arm flexing / extending arm 31 is mounted on the upper portion of the back support 23 so as to be swingable around the horizontal axis 29 fixed and supported at the upper position from the upper end of the backrest.

Between the inside of the main body frame 21 and the support pipe 30, a drive mechanism for swinging and driving an upper arm bending / extending arm 31 as shown in FIGS. 3 to 6 is disposed. More specifically, as shown in FIG. 3, the main body frame 21 is provided with a swing drive source 32 such as a gear motor. A connecting rod 33 is provided at the upper and lower portions of the back support 23 and is provided with two sliding support members 34. The support support 34 is fixed to the back support 23 with fixing bolts 35 (see FIG. 4) in the longitudinal direction. It is slidably supported by. If the sliding support member 34 is assembled to the connecting rod 33 in advance and is inserted into the back support 23 and assembled, the assembling work is facilitated. Further, the sliding support member 34 can be omitted by supporting the sliding of the connecting rod 33 by the inner surface of the back column 23. The upper end of the connecting rod 33 and the support pipe 30 are hinged by a connecting arm 36 and a connecting link 37 projecting from the supporting pipe 30! /, And a crank having the connecting arm 36 as a drive link. The connecting rod 33 is moved linearly by the mechanism. In order to allow the connecting arm 36 and the connecting link 37 to swing, as shown in FIG. 4, an opening 23a is formed in the back column 23 and is covered with a cover 38. Yes. A crank mechanism that linearly moves the connecting rod 33 is also connected to the lower end of the connecting rod 33. That is, the drive link 40 is swingably mounted on a support shaft 39 installed horizontally on the main body frame 21, and the drive link 40 and the lower end of the connecting rod 33 are hinged by the connecting link 41, thereby driving the drive link 40. The connecting rod 33 is moved linearly by swinging. Further, the rocking plate 42 is fixed to the output shaft 32a of the rocking drive source 32, and the rocking plate 42 and the drive link 40 are hinge-coupled to each other by the connecting link 43 to thereby connect the drive link 40. Try to rock it.

[0022] As shown in FIGS. 1 and 2, a lower leg flexion / extension arm 45 is supported by a peristaltic shaft 44 at the lower portion of the left side surface of the main body frame 21 so as to be swingable around a horizontal axis. And A support shaft 46 extending in the center direction is projected in a cantilevered manner at the tip of the lower limb flexion / extension arm 45, and two pedals 47 on which the user puts his / her foot on the support shaft 46 are supported by the support shaft. It is mounted so that it can rotate freely. Known from the swing drive source 32 to the swing shaft 44 In the same way as in the example, the power is transmitted. In addition, a stabilizing stay 48 protrudes from the left and right front of the lower end of the main body frame 21, and a control unit 49 equipped with a CPU and input means is attached to the tip of the right stabilizing stay 48 by a stand 50. ing.

Next, the operation of this embodiment will be described.

[0024] First, the user sets the position of the backrest 24 to an appropriate position with the prism 25, the support tube 26 and the positioning pin 27 so as to match his / her physique. This allows appropriate training according to the user's physique.

Next, the user sits on the seat section 22 and sends a training start command from the control section 49. As a result, the swing drive source 32 is turned on, and the output shaft 32a is swung. The swinging output is transmitted to the connecting rod 33 through the driving link 40 and the connecting link 41 through the swinging plate 42 and the connecting link 43, and the connecting rod 33 is reciprocated linearly in the back column 23. The reciprocating motion of the connecting rod 33 is transmitted to the support pipe 30 through the connecting link 37 and the connecting arm 36, and the upper arm bending / extending arm 31 is swung up and down around the horizontal axis 29.

[0026] With this, the user can hold the gripping portion 3la at the tip of the upper arm flexing / extending arm 31 to perform training for automatically extending and retracting the upper arm.

In the present embodiment, the upper arm flexing / extending arm 31 is fixedly supported by the rear support 23 at a position above the upper end of the backrest 24 and is relatively high! Centered on the horizontal axis 29 of the position. As the arm 31 for bending and extending the upper arm reaches a horizontal position, the stroke that rises until it reaches the horizontal position becomes longer, and the position of the gripping part 31a only moves forward during that stroke. Mu As a result, the load on the user does not change excessively during the stroke of the stretching exercise, and a safer and more appropriate exercise can be provided without the user feeling uneasy.

Similarly, the lower limb flexion / extension arm 45 also swings up and down around the swing axis 44 so that when the user puts his / her foot on the pedal 37, the lower limb flexion / extension movement can be performed. it can.

[0029] The movements of the upper arm and lower limbs can bend and stretch throughout the body if both are extended simultaneously and contracted simultaneously.

[0030] According to the present embodiment, the entire apparatus of the training apparatus 20 can be formed in a small size. It is possible to allow the user to perform an appropriate exercise in which the load does not change excessively during the stroke of the stretch exercise, and to suppress the stress acting on each part of the drive system to be small and to increase the durability of each part of the configuration. it can.

[0031] In particular, since the upper arm flexing / extending arm 31 is integrally fixed to the support pipe 30 having a relatively large diameter, the stress acting on the base portion of the arm 31 can be suppressed to be extremely small and the durability can be enhanced. It is out.

[0032] Further, the connecting rod 33 can be accommodated in the back column 23 so as to be linearly movable, and the apparatus can be further reduced in size.

Note that the present invention is not limited to the above-described embodiments, and various modifications can be made as necessary.
