Description

  The present invention relates to an exercise assisting device for performing various arm opening and closing exercises using both hands.

  Conventionally, an expander is widely known as an exercise assisting device for performing an arm opening / closing exercise.

  In addition, in order to allow elderly people and sick people to use for rehabilitation, a stretcher is provided on a wearable part that can be attached to and removed from a part of the body, and the stretcher is attached to the part of the body. Japanese Patent Application Laid-Open No. 2004-133867 discloses an exercise assisting device that extends a hand by grasping a provided grip portion.

  In any of the above-described conventional examples, the expander and the expansion / contraction tool are deformable ones provided with a spring such as a coil spring, and in use, the user grips the holding part with both hands and resists the spring force. Arms and shoulders are trained by pulling them so that the distance between their hands increases.

  As described above, in the conventional device, the exercise assisting device itself does not automatically expand and contract, and when the user applies a pulling force in a direction in which the user grasps the holding part with both hands and separates both hands, The force in the direction approaching both hands, which is the direction opposite to the direction in which it is applied, was applied by a spring, and only a load was applied to the arm and shoulder.

However, people with hard bodies, lack of exercise, people with 40 shoulders or 50 shoulders, elderly people, sick people, etc. have limited arm movement, elbow joints and shoulder joints, and the range of motion is limited. The range of motion of the motor is limited, or the motor function is impaired such that the movement within the range of motion is not smooth. Thus, even if a person with a limited range of motion of the arm tries to expand the range of motion that is hard and difficult to move, or trying to recover the function of movement within the range of motion, the above-described conventional exercise assistance device is When the user applies a force in the direction of pulling with both hands (the direction in which both hands separate), the load is limited by the spring in the opposite direction to the pulling force, so the range of motion is limited or movable as described above. It cannot be used as an exercise assisting device for performing functional recovery exercise for smooth movement in the region.

  The present invention has been invented in view of the above-described conventional problems, and it is possible to recover the motor function of expanding the movable range of the arm that is hard and difficult to move, or smoothing the movement of the arm within the movable range. It is an object of the present invention to provide an exercise assisting device that can effectively improve.

  In order to solve the above-described problem, the exercise assisting apparatus according to the present invention is configured so that the stretchable body 2 having the grip portions 1 at both ends can be stretched in a specific direction, and the stretchable body 2 is driven to extend and retract the stretchable body 2. It is characterized by comprising a source 3.

  By adopting such a configuration, the expansion body 2 is automatically expanded and contracted by driving the drive source 3 while holding the grip portions 1 at both ends of the expansion body 2 with both hands. A function recovery exercise for expanding the range of motion of the arm that is hard and difficult to move using the stretching force, or a function recovery exercise that results in a smooth movement within the range of motion of the arm can be performed.

  Moreover, it is preferable that the expansion / contraction body 2 is a rod-shaped expansion / contraction body 2a having a rod shape, and is extendable / contractible in the longitudinal direction of the rod-shaped expansion / contraction body 2a. Function-recovering exercise for expanding the range of movement of the arm using the longitudinal stretching force of the rod-shaped expansion / contraction body 2a by grasping the gripping portions 1 at both ends, or smooth movement within the range of movement of the arm Can perform functional recovery exercises.

  Further, it is preferable that a plurality of rod-like portions 4 are slidably connected in the longitudinal direction to constitute the rod-like stretchable body 2a. With such a construction, the arm can be automatically stretched to move the arm. The stretchable body 2 for expanding the area or smoothing the movement of the arm within the movable range can be easily configured.

  In the present invention, as described above, the stretchable body having the gripping portions at both ends can be stretched in a specific direction, and the stretchable body is provided with a drive source for expanding and contracting the stretchable body. Recover or enhance the motor function by gripping the grip part of the hand with the hand and expanding the range of motion of the arm that is hard and difficult to move, or smoothing the movement within the range of motion of the arm using the expansion and contraction force of the elastic body Can be effective.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The exercise assisting device of the present invention is configured by including a drive source 3 for expanding and contracting the expansion / contraction body 2 on the expansion / contraction body 2 that has the gripping portions 1 at both ends. Here, the stretchable body 2 is freely stretchable in a specific direction (for example, a direction in which the distance between the gripping portions 1 at both ends becomes longer or shorter).

  In the embodiment shown in the accompanying drawings, an example in which the expansion / contraction body 2 is a rod-shaped expansion / contraction body 2a having a rod shape is shown, and the gripping portions 1 are provided at both ends in the longitudinal direction of the rod-shaped expansion / contraction body 2a. Here, the `` bar '' in the present invention may be a solid bar or a hollow cylindrical bar inside, and may be either a straight line or a curved line. It suffices if the rod-like stretchable body 2a having a rod shape is freely stretchable.

  The rod-shaped elastic body 2a is configured by connecting a plurality of rod-shaped portions 4 so as to be slidable in the longitudinal direction. In the embodiment shown in the accompanying drawings, separate rod-shaped members are provided on both sides of the central rod-shaped portion 4a which is the rod-shaped portion 4. The left and right side bar-shaped portions 4b, which are the portion 4, are configured to be slidable in the longitudinal direction.

  In the embodiment shown in FIG. 1, the central rod-like portion 4 a has left and right screw rods 7 on the output shaft 6 of the drive source 3 including the motor 3 a and the speed reduction portion 3 b provided in the center of the central cylinder portion 5. The left and right screw rods 7 protrude outwardly from both end openings 8 of the central cylinder portion 5 so as to be rotatable outwardly, and male screw portions 9 and 10 having a reverse screw relationship with each of the left and right screw rods 7 are respectively attached. It is provided and formed. Further, the left and right side bar-like portions 4b are formed by providing the grip portion 1 at one end portion of the side tube portion 13 in which the internal thread portions 11 and 12 having a reverse screw relationship are formed inside.

  And the front-end | tip part of the side cylinder part 13 of the right-and-left side part rod-shaped part 4b is each inserted in the center cylinder part 5 from the right and left opening part 8 in the center cylinder part 5 so that it can shallowly shallow, and the left and right side cylinder parts 13 The male screw portions 9 and 10 of the left and right screw rods 7 are respectively screwed into the female screw portions 11 and 12. Here, the side tube portion 13 is slidably fitted in the opening portion 8 of the central tube portion 5 so as to be slidable in the longitudinal direction but not rotatable. For example, the side tube portion 13 having a non-circular cross section is fitted into the non-circular opening 8 so as to be slidable and cannot rotate. Therefore, the left and right side tube portions 13 and the central tube portion 5 cannot rotate with each other. When the motor 3a is rotated with the grip portions 1 on both the left and right sides being gripped by hand, the left and right screw rods 7 are rotated. The screwing depth between the male screw part 9 and the female screw part 11 and the screwing depth between the male screw part 10 and the female screw part 12, which are in a reverse screw relationship with each other, become shallower or deeper. Thus, the rod-like stretchable body 2a having the grip portions 1 at both ends is automatically extended or contracted in the longitudinal direction (axial direction).

  In the embodiment shown in FIG. 2, the central rod-shaped portion 4 a is composed of the outer cylindrical portion 5 a and the inner cylindrical portion 5 b that is disposed in the outer cylindrical portion 5 a so that the central cylindrical portion 5 that constitutes the main body is extendable. An air pump 3d is provided in the center of the central cylinder portion 5 of the central cylinder portion 5, and the air pump 3d is connected to the inner cylinder portion 5b. Further, the central cylinder portion 5 is provided with an exhaust portion (not shown). The inner cylinder part 5b is a bellows-like cylinder part 5c that can expand and contract at both left and right ends, and the tip part of the bellows-like cylinder part 5c is closed.

  Further, the left and right side bar-shaped portions 4 b are formed by providing the grip portion 1 at one end of the side tube portion 13. The side tube portions 13 of the left and right side bar portions 4b are slidably fitted between the outer tube portion 5a and the inner tube portion 5b of the center tube portion 5 on the left and right sides of the center rod portion 4a. Further, the left and right side bar-like parts 4b are connected to the central bar-like part 4a by a spring material 3e such as a tension spring, respectively, so that the left and right side bar-like parts 4b give a spring force in a direction approaching each other. Accordingly, the distal end portion of the elastic bellows-like cylindrical portion 5 c is in contact with the cylindrical bottom portion 14 of the side cylindrical portion 13.

  When the air pump 3d is driven to supply pressurized air to the inner cylinder portion 5b, the telescopic bellows-like cylinder portions 5c at the left and right end portions of the inner cylinder portion 5b expand, and the left and right bellows-like cylinder portions 5c expand. The rod-shaped elastic body 2a extends in the longitudinal direction (axis) so that the space between the left and right side cylinder parts 13 spreads against the spring force of the spring material 3e by pushing the cylinder bottom parts 14 of the left and right side cylinder parts 13 respectively. And automatically contracts by the spring force of the spring material 3e so that the space between the left and right side tube portions 13 is shortened by exhausting from the exhaust portion (not shown). Therefore, in this embodiment, the drive source 3 for automatically expanding and contracting the expansion / contraction body 2 by the air pump 3d and the spring material 3e is configured.

  Further, in the embodiment shown in FIG. 3, the rod-shaped elastic body 2a is an example in which it is curved in an arcuate shape, and the outer cylinder part 5a and the inner cylinder part 5b of the central cylinder part 5 are each curved in an arcuate shape. Further, the side tube portions 13 of the left and right side bar portions 4b are respectively curved in an arcuate shape. In the present embodiment, the configuration other than that described above in which the rod-like stretchable body 2a is curved in an arcuate manner is the same as that of the embodiment shown in FIG.

  The above-described exercise assisting device of the present invention automatically expands and contracts the telescopic body 2 by driving the drive source 3 while holding the grips 1 at both ends of the telescopic body 2 (rod-shaped telescopic body 2a) with both hands. By performing the function recovery exercise for expanding the range of movement of the arm that is hard and difficult to move by using the expansion / contraction force of the expansion body 2, or the function recovery exercise for smooth movement within the range of movement of the arm Is.

  For example, if the shoulder joint is solidified at forty shoulders or fifty shoulders and the range of motion is limited, and the rotation range of the shoulder is limited for the movement of turning both arms toward the back, When performing a function recovery exercise to exceed the rotation range, it is necessary to move both hands toward the back and bring both hands as close as possible. In this case, the gripping portions 1 at both ends of the stretchable body 2 positioned on the back in a state where one arm is raised and bent toward the back and the other arm is lowered and bent toward the back are held with both hands. The movement assisting device according to the present invention can assist in the movement that the hands 2 that are turned toward the back are separated or approached by the gripping and automatically extending or contracting the telescopic body 2 by the driving source 3. In particular, by alternately extending and contracting, the movement of assisting movement that restores the function by gradually exceeding the restricted shoulder rotation range is made, and as described above, forty shoulders and fifty shoulders, etc. In this case, it is not possible to move the two hands turned to the back beyond the limited rotation range by one's own power, but it is possible to give the force to pull both hands so that the two hands turned to the back automatically approach. , Get help in the direction that both hands turned towards this back It is functional recovery in excess of the rotation range of limited shoulder by.

  Here, as shown in the embodiment shown in FIG. 3, when the rod-shaped elastic body 2 a is curved in a bow shape, even if it is a person who is unable to turn both hands toward the back because the shoulder indirect is solidified, Both grips 1 can be positioned on the front side of the body with 2a positioned on the back side, and the above-mentioned limitations are imposed on both grips 1 held with both hands on the front side of the body. It is possible to perform a function recovery exercise to exceed the rotation range of the shoulder joint.

  Of course, the above use example is one use example of the exercise assisting device of the present invention, and a person who can extend both arms only to a range where the opening / closing range of both arms is limited exceeds the limited opening / closing range. Can be used as an aid for various functional recovery exercises.

  In addition, arm muscles, elbow joints and shoulder joints are hardened and the range of motion is limited, so that the range of motion of the arm is limited, or the function of people with motor impairments such as inability to move smoothly within the range of motion It can be used not only as an aid for exercise but also as an aid for stretching exercise for healthy people.

  In the embodiment shown in the accompanying drawings, the example in which the expansion / contraction body 2 is configured by the rod-shaped expansion / contraction body 2a is shown, but the expansion / contraction body 2 may be other than a rod shape, for example, a band shape.
