Description

In the present invention, when the muscle serving as the main muscle contracts and the muscle serving as the antagonist muscle expands, the muscle strength is enhanced by contracting the muscle serving as the main muscle or antagonist muscle by applying electrical stimulation. The present invention relates to a muscular strength enhancer.
More specifically, for example, the present invention relates to a device in which the forearm can be moved smoothly even when the distance or angle between the training device and the motion device is changed due to the bending or extension of the forearm or the like.

  Conventionally, what was disclosed by patent 3026007 is known as a muscular strength enhancer which can be exercised by a closed movement chain, for example. “Exercise by the closed movement chain” refers to a movement in which antagonistic muscles work together with main muscles. Here, the terms are explained. The term “primary muscle” shown in the present specification and claims means “muscle that contracts and stretches and bends the knee, elbow, and the like”. The term “antagonist muscle” means “muscle that stretches when the knee, elbow, etc. are stretched and bent by the main muscle”. The main muscles and antagonist muscles work against each other, and simultaneously perform opposite movements.

  According to this muscle strength enhancer, since the antagonistic muscle can be contracted when the main muscle is contracted, the muscle strength of the antagonistic muscle can be maintained or enhanced together with the main muscle. In addition, since the load on the main muscle is increased as compared with the case of the open movement chain, there is an effect that the efficiency for maintaining and enhancing the muscle strength of the main movement muscle is better than that in the case of the open movement chain.

The embodiment of the above publication includes a thigh orthosis to be attached to the thigh and a thigh orthosis to be attached to the thigh in cooperation with the thigh orthosis. Attach the thigh brace so that it does not move, and similarly wear the thigh brace on the crus so that it does not move. What is used by reciprocatingly rotating around a goniometer is disclosed.

Bending and stretching in human arms and legs, etc., seems to be a movement that moves the joint part about the center if you look only at the skeleton, but for this movement the muscles around the joint are intricately stretched, The movement is not a simple rotational movement. In other words, the muscle strength enhancer is used by attaching the thigh orthosis and the crus orthosis so that it does not move, and since it could only rotate around the goniometer, Even simple movements such as stretching and bending tend to cause resistance that hinders movement, making it difficult to move.

In addition, the thigh orthosis and the crus orthosis are connected so that they can perform simple reciprocating rotation, and since the direction of joint movement is restricted when worn, they cannot be moved freely.

The controller 4 controls to supply electricity to the electrical stimulation units 12 and 13 when the switch member 32 detects that the angle between the upper arm device 1 and the forearm device 2 has changed by moving the forearm portion 91. Control means.
The controller 4 supplies electricity to the electrical stimulation unit 12 and the electrical stimulation unit 13 by an electrical supply unit that supplies electricity to the electrical stimulation units 12 and 13 and one or the other of the micro switches 322 and 323 that have detected movement. Regardless of the control unit that performs control or the microswitches 322 and 323, a control unit that arbitrarily supplies electricity to the electrical stimulation unit 12 or the electrical stimulation unit 13 to apply electrical stimulation to the muscle is provided. Furthermore, a means for selecting these control units is provided. This selection means is operated by a changeover switch 40 provided in the controller 4.

(Work)
With reference to FIG. 1 thru | or FIG. 3, the motion of the connection apparatus 3 accompanying the bending | flexion and extension of the forearm part 91, the effect | action of the muscular strength enhancer K1, and the exercise | movement of a muscle are demonstrated.

  The muscular strength enhancer K1 is attached by attaching the upper arm orthosis 1 to the upper arm 90 and attaching the forearm orthosis 2 to the forearm 91. More specifically, the upper arm portion base material 10 is wound around the upper arm portion 90 and attached so as not to move by the hook-and-loop fastener 11, and the forearm portion base material 20 is wound around the forearm portion 91 and attached so as not to move by the hook-and-loop fastener 21. The

  Assume that the coupling device 3 is in the state shown in FIG. 3A as an initial state when the muscle strength enhancer K1 is attached. At this time, the coupling device 3 is in a state in which both lever members 326 and 327 are opened and the switch is not turned on, and electricity is not supplied to the electrical stimulation units 12 and 13. Further, the controller 4 is set by the changeover switch 40 so as to have the modes (1) and (3).

A case where the forearm 91 is bent will be described.
The exercise | movement which bends the forearm part 91 is performed when the biceps brachii which are main muscles contract. When the biceps muscle contracts, the triceps muscle, which is an antagonistic muscle, simultaneously expands.

  When the forearm portion 91 is bent from the state shown in FIG. 3A, the forearm portion side connection body 31 of the connecting device 3 starts to rotate around the rotation pin P. The forearm portion side connection body 31 is connected to the upper arm portion side connection body 30 via the bearing B, and the switch member 32 is connected to the upper arm portion side connection body 30 with the base member 321 in contact with the wall portion. Therefore, only the forearm side connection body 31 is initially rotated because the frictional resistance values are different, and the switch member 32 is not rotated.

  As the forearm-side connecting body 31 rotates, the connecting arm member 310 contacts the lever member 326, and the contact member 328 is pressed by rotating from the opened state to the closing direction. When the contact 328 is pressed, the microswitch 322 is turned “ON”, and it is detected that the forearm portion 91 is moving in the bending direction.

  When the microswitch 322 detects the movement of the forearm 91 in the bending direction, the information is transmitted to the controller 4 and electricity is supplied from the controller 4 to the electrical stimulation unit 13 provided on the side of the triceps, which is an antagonistic muscle. Is done.

  Then, the forearm portion 91 is further bent and the forearm portion side connecting body 31 is rotated, whereby the microswitch 322 is pushed by the forearm portion side connecting body 31, and the switch member 32 follows and the wall in the groove portion 302 is also followed. It rotates while sliding with the part (see FIG. 3B). When the switch member 32 is rotating, the contact 328 is pushed by the lever member 326, so that electricity is continuously supplied to the electrical stimulation unit 13.

  When the forearm portion 91 is bent as described above, the forearm portion-side connecting body 31 places the front portion side of the connecting arm member 310 in the fixing member 312 even if the distance of the forearm device 2 to the upper arm portion 1 changes. Since the fixing member 312 and the connecting arm member 310 are relatively moved, the distance can be changed. Therefore, the forearm portion 91 can be bent smoothly.

  Further, in the muscle strength enhancer K1, the rotating part 300 for connecting the forearm part side connecting body 31 is provided so as to be rotatable in the axial direction by the rotating shaft 301, so that the forearm apparatus 2 is attached. It can also be moved in the twisting direction.

The case where the bent forearm 91 is extended will be described.
The exercise for extending the forearm portion 91 is performed by contraction of the triceps surae which is the main muscle. When the triceps are contracted, the biceps, which is an antagonistic muscle, simultaneously expands.

  When the forearm portion 91 is extended from the state shown in FIG. 3B, the forearm portion side connecting body 31 starts to rotate around the rotation pin P in the direction opposite to that during bending. The forearm portion side connection body 31 is connected to the upper arm portion side connection body 30 via the bearing B, and the switch member 32 is connected to the upper arm portion side connection body 30 with the base member 321 in contact with the wall portion. Therefore, in this case as well, similarly to the bending, first, only the forearm side connection body 31 is rotated, and the switch member 32 is not rotated.

  By rotating only the forearm portion side coupling body 31, the lever member 326 that has been pushed so far returns to maintain the original open state. As a result, the contact 328 protrudes, the micro switch 322 is turned “OFF”, and the supply of electricity to the electrical stimulation unit 13 is stopped.

  Further, when the forearm portion side connecting body 31 is further rotated, the connecting arm member 310 is brought into contact with the lever member 327, and the lever member 327 is rotated in the closing direction to press the contact 329. When the contact 329 is pressed, the microswitch 323 is turned “ON”, and it is detected that the forearm portion 91 is moving in the extending direction.

  When the microswitch 323 detects the movement of the forearm portion 91 in the extending direction, the information is transmitted to the controller 4, and then electricity is supplied to the electrical stimulation unit 12 provided on the biceps muscle side that is an antagonistic muscle. Is done.

  Then, by further extending the forearm portion 91 and rotating the forearm portion side coupling body 31, the microswitch 323 is pushed by the forearm portion side coupling body 31, and the switch member 32 also follows and slides while rotating. (See FIG. 3C). When the switch member 32 is rotating, the contact 329 is pushed by the lever member 327, so that electricity is continuously supplied to the electrical stimulation unit 12.

  Even when the forearm 91 is extended in this manner, if the distance of the forearm brace 2 to the upper arm brace 1 changes, the fixing member 312 and the connecting arm 310 can move relative to each other to change the distance. Therefore, the forearm portion 91 can be extended smoothly.

  In the muscular strength enhancer K1, since the entire length of the forearm portion side coupling body 31 is configured to freely change, when the distance of the forearm device 2 relative to the upper arm device 1 changes due to bending or extension But you can move. For this reason, in the muscle strength enhancer K1, the forearm portion 91 can easily move even when the upper arm device 1 and the forearm device 2 are mounted.

The brace 5 has flexibility, stretchability, or elasticity, and is formed of a material that can be worn in close contact from the upper arm 90 to the forearm 91, and is formed in a shape that can be worn in the above state. As a material for forming the brace 5, for example, a material formed of a material such as jersey (a stretchy thick knitted fabric) or sponge rubber can be used.

  Inside the one end side of the appliance 5, electrical stimulation units 12 and 13 are provided at two locations.

FIG. 7 is an explanatory diagram showing waveforms formed by the detection device and their states.
With reference to FIG. 4 thru | or FIG. 7, the motion of the detection apparatus 6 accompanying the bending and extension of the forearm part 91 and the effect | action of the muscular strength enhancer K2 are demonstrated.
In addition, description is abbreviate | omitted about the same effect | action and effect which arise with the structure common to the above-mentioned muscle strength enhancer K1, and only a different point is demonstrated.

The muscular strength enhancer K2 is provided such that the arm is inserted into the brace 5 so that the electrical stimulation unit 12 corresponds to the biceps brachii and the electrical stimulation unit 13 corresponds to the triceps brachii, the forearm 91 and the upper arm Attached in close contact with the skin of the part 90.
As an initial state when the muscle strength enhancer K2 is attached, the forearm portion 91 is extended, and the case member 60 and the slide member 61 of the detection device 6 are in the state shown in FIG. At this time, electricity is not supplied to the electrical stimulation units 12 and 13. The controller 4 is set so as to have the above aspects (1) and (3).

A case where the forearm 91 is bent will be described.
In the state where the forearm portion 91 is extended, the detection device 6 is in a state where the slide member 61 is entirely accommodated in the case member 60. In the detection device 6, since the distal end of the slide member 61 and the proximal end side of the case member 60 are fixed to the brace 5, when the forearm portion 91 is bent from this state, the brace 5 is deformed as it is bent. The detection device 6 is also deformed. In this way, the distance between the fixed position (reference point) of the slide member 61 and the fixed position (reference point) of the case member 60 begins to increase, and a part of the accommodated slide member 61 is exposed to the outside of the case member 60. (See FIG. 5).

Please refer to FIG.
At this time, in the detection device 6, the movable contacts 605, 606 are pushed by the fixed contacts 611... 612. By doing so, it is “OFF”. This information is transmitted to the controller of the controller 4, thereby measuring the ON / OFF waveform.

This will be specifically described. In the actual operation, both the case member 60 and the slide member 61 are moving. However, here, for convenience, the description will be made on the assumption that the slide member 61 does not move and only the switch members 600 and 601 move.
When the forearm portion 91 is bent from the state shown in FIG. 6, the switch members 600 and 601 are moved to the left. In this way, when the movable contact 605 (606) of the switch member 600 (601) is pushed by the fixed contact 611 (612), it is “ON” and a waveform indicating the ON state is formed. When the movable contact 605 (606) of the switch member 600 (601) protrudes from the accommodated state, the switch member 600 (601) is turned off, and a waveform indicating the OFF state is formed. Further, although the switch member 600 and the switch member 601 are provided to face each other, the fixed contacts 612... And the fixed contacts 611. In this way, the waveform on the side A shown in FIG. 7 is measured.

When the forearm portion 91 is bent in this way, the switch members 600 and 601
(A) From “Switch member 600 is ON and switch member 601 is ON” to “Switch member 600 is ON and switch member 601 is OFF”
(B) From “Switch member 600 is ON and switch member 601 is OFF” to “Switch member 600 is OFF and switch member 601 is OFF”
(C) “When the switch member 600 is OFF, the switch member 601 is also OFF”, and when bent, “When the switch member 600 is OFF, the switch member 601 is ON”
(D) Any pattern that changes from “switch member 601 is ON when switch member 600 is OFF” to “switch member 601 is ON when switch member 600 is ON” at the time of bending appears.
Each of these patterns is stored in advance in the control unit of the controller 4 as [bent state]. Therefore, when any pattern is measured, it is detected that the control unit is bent, and electricity is supplied from the controller 4 to the electrical stimulation unit 13 provided on the side of the triceps muscle which is an antagonistic muscle. Is done.

The case where the bent forearm 91 is extended will be described.
When the forearm portion 91 is extended from the bent state, the brace 5 is deformed along with the bending, and the distance between the fixed portion of the slide member 61 and the fixed portion of the case member 60 starts to be reduced due to this deformation. Thus, the slide member 61 is accommodated in the case member 60.

Please refer to FIG.
At this time, in the detection device 6, the movable contacts 605, 606 are pushed by the fixed contacts 611... 612. It may be “OFF” by protruding. As a result, the waveform is measured.

This will be specifically described. Here, it is assumed that the slide member 61 does not move and only the switch members 600 and 601 move.
When the forearm portion 91 is extended from the state shown in FIG. 6, the switch members 600 and 601 are moved to the right. In this way, the waveform on the side B shown in FIG. 7 is measured.

When the forearm 91 is extended in this way, the switch members 600 and 601
(E) From “Switch member 600 is OFF and switch member 601 is ON” to “Switch member 600 is OFF and switch member 601 is OFF”
(F) From “Switch member 600 is OFF and switch member 601 is OFF” to “Switch member 600 is ON and switch member 601 is OFF”
(G) From “switch member 600 is ON and switch member 601 is OFF” to “switch member 600 is ON and switch member 601 is ON”
(H) Any pattern that changes from “switch member 600 is ON and switch member 601 is ON” to “switch member 600 is OFF and switch member 601 is ON” appears.
Each of these patterns is different from the above-mentioned [bent state]. Each of these patterns is stored in advance in the control unit of the controller 4 as [extending state]. Therefore, when any pattern is measured, it is detected that the controller is extending, and electricity is supplied from the controller 4 to the electrical stimulation unit 12 provided on the biceps brachii muscle that is an antagonistic muscle. Is done.

  Although not specifically described in the present embodiment, the controller 4 can measure the number of “ON” or “OFF” portions of the measured waveform. As a result, it is possible to measure the bending amount (bending angle) and the extending amount (extending angle) of the forearm portion 91.

  In the muscle strength enhancer K2, the brace 5 is formed of a material having flexibility, stretchability, or elasticity, and the detection device 6 provided along the brace 5 is also deformable or flexible. When the case member 60 is bent, the case member 60 and the slide member 61 can be slid so as to increase or decrease the distance between the reference points. As a result, it is possible to cope with the direction of movement of the joint movement in the mounted state. Therefore, according to the muscular strength enhancer K2, for example, it is also possible to send a daily life while wearing.

The sensors 700 and 701 are configured to be guided through the slide member 71 inside. The sensors 700 and 701 are turned “ON” when the lower side light receiving unit 703 receives the light emitted from the upper side irradiation unit 702 at the measurement point indicated by the dotted line in FIG. When the light receiving unit 703 does not receive the signal, it is “OFF”.

In the slide member 71, window holes 710 (openings) having a predetermined width are formed at equal intervals in the length direction.
The distance between the measurement points in the sensor 700 and the sensor 701 is set to be ¼ width shorter than 1 when the distance between the window holes 710 and 710 is 1. In addition, the distance between the measurement points in the sensor 700 and the sensor 701 and the distance between the window holes 710 and 710 are not limited to those described above, and are detected as being bent or extended by the control unit.
