Description

  The present invention relates to an exercise apparatus used in a sitting position or a supine position for performing an exercise in a sitting position such as a long sitting position with a left or right leg extended or a supine position. More specifically, it can effectively stimulate the back of the knee in a sitting posture with no weight applied to the knee and can strengthen the quadriceps muscle strength to relieve knee pain as well as no knee pain disease. Even the user can effectively exercise the legs, and also the whole body exercises through the movements of the legs, and even the elderly can sit safely or lie supine without fear of falling It is related with the exercise equipment used in.

  Among the causes of knee joint pain, the proportion of knee osteoarthritis is high. Knee osteoarthritis is a disease that causes pain in the knee joint due to a state where the cartilage of the knee joint having a cushion function is worn down and the bones rub against each other due to muscle weakness, aging, obesity, and the like.

  Exercise is considered important for the improvement of knee osteoarthritis. In particular, strengthening the strength of the quadriceps is the mainstream concept. However, people with knee pain cannot perform exercises using walking or running knees, so the muscles cannot be strengthened by exercise and the knee pain will not improve and the knee pain will worsen. Become.

  As one of means for relieving knee pain caused by knee osteoarthritis or the like, a knee mounting supporter disclosed in Patent Document 1 has been proposed. As shown in FIG. 45, the knee-mounting supporter a has an elastic upper fixing part c that is wound around and fixed to the upper part of the knee b, and a lower fixing part that is fixed by being wound around the lower part of the knee b. d and a cover part f covering the back e of the knee joint, and a pad part made of a resilient material was mounted inside the cover part f. The pad portion presses the bent portion of the back of the knee by the tension of the upper fixing portion c, the lower fixing portion d, the cover portion f, and the elasticity of the pad portion. The meniscus sandwiched behind the knee joint gap is pushed forward of the knee, thereby preventing the meniscus from slipping, thereby maintaining the knee joint gap and relieving knee pain. It was. In addition, the knee-mounted supporter a is intended to relieve knee pain by reducing the effect of body weight on the knee joint by an assisting action that assists in reducing the muscle strength around the knee joint. It was.

  Further, in Patent Document 2, in order to alleviate knee pain, it is important to expand the knee joint to some extent to facilitate the flow of joint fluid as a lubricant between the knee joints. A knee pain alleviation assisting device h shown in 46 is proposed. The knee pain relief assisting device h is applied to the back e of the user's knee b, and is sandwiched between the bending gaps when the user bends the knee b to open the knee joint like a lever. A backing member j, holding means k that holds the knee-backing member j placed on the back of the knee even if the user bends the knee while the knee-backing member j is applied, and the knee-backing In the state where the member j is applied to the back of the user's knee, there is provided pulling assisting means m for pulling the position closer to the user's ankle toward the user and forcibly bending the knee. When using the knee pain alleviation assisting device having such a configuration, the knee joint can be opened like a lever, so that joint fluid can easily flow into the open knee joint and the cartilage is moistened to restore the cushion function of the knee. I could expect, so I was able to alleviate knee pain from this aspect. Further, the knee pain relief assisting device h is configured so that knee bending can be assisted through the traction assisting means m in a state in which the knee backing member j is linked to the holding means k. It was difficult to slip off from the back of the knee, which was expected to reduce the knee pain.

  As described above, in order to relieve pain in the knee, it is effective to expand the knee joint to some extent so that the joint fluid as a lubricant can easily flow between the knee joints. In this sense, it is effective that the knee pain alleviation assisting device described in Patent Document 2 is provided with a knee support member that is sandwiched in a bending gap when the user bends the knee and expands the knee joint like a lever. It can be said that it is a safe means. However, Patent Document 2 does not describe any means for effectively exercising quadriceps important for knee pain alleviation, and there is no description suggesting this.

  In addition, as pointed out in Patent Document 2, the knee pain relieving support described in Patent Document 1 has a relatively weak pressing force from the back side of the knee by the pad portion, so that the knee joint is sufficiently expanded to The joint fluid as the lubricating fluid cannot easily flow between the expanded knee joints, and there is a fear that the knee pain may not be sufficiently relieved. In paragraph 0022 of Patent Document 1, there is a description of the quadriceps muscle that is not mentioned in Patent Document 2. That is, in the same paragraph, it is described that “the tension of the upper fixing part and the lower fixing part acts in the direction of bending the knee when bending and stretching the knee, and thus has an auxiliary action of the quadriceps muscle”. . However, the knee pain relieving supporter only has an assisting action for the quadriceps muscles, and has not been able to reinforce the muscle strength of the quadriceps important for knee pain relief.

  FIG. 7A shows a state where the substrate 17 is placed on the seat surface 13 of the chair 11 and the user is seated on the chair 11. As shown in FIG. 1, the substrate 17 is placed on the seat surface 13 in a long state in the front-rear direction, and the front edge side portion 19 of the substrate 17 protrudes forward from the front edge 20 of the seating portion 12. The user 2 sits on the base plate 17 with the buttocks on the base plate 17. Then, the user 2 puts the knee back portions 5 and 5 of the left and right leg portions 55 and 55 on the left and right knee receiving portions 6 and 6 and hangs the left and right lower leg portions 56 and 56, and the left and right hands 57. 57 hold the upper portion 24 of the handle 25. In this state, the left and right feet 59, 59 are lifted from the floor surface 60, and the left and right knee back portions 5, 5 are substantially directly above the upper portion due to the weight of the left and right leg portions 55, 55 of the user. The pressure stimulus is given to. That is, the left and right knee back portions 5, 5 are massaged by the weight of the user's own leg portions 55, 55.

[About the first movement mode]
7 (B) and 7 (C) show that when the handle 25 is in a vertically projecting state, the user flexes and stretches the left and right leg portions 55 and 55 using the weights of the left and right lower leg portions 56 and 56. It shows the state of repeating. FIG. 7B shows a state where the left and right leg portions 55, 55 are extended forward, and FIG. 7C shows a state where the left and right leg portions 55, 55 are bent backward. Yes. By this movement, the left and right knee support portions 6 and 6 can repeatedly apply pressure stimulation to the left and right knee back portions 5 and 5. As a result, the left and right knee back portions 5 and 5 are effectively massaged, and the blood circulation of the left and right knee back portions 5 and 5 is promoted and the knee joint is enlarged. In addition, the muscle strength of the quadriceps can be strengthened through these exercises. These exercises are performed in a state where the left and right feet 59, 59 are lifted from the floor surface 60, so that they can be easily performed without putting weight on the left and right knees 3, 3. However, this exercise can relieve knee pain. When the left and right knees 3 and 3 are bent, if the calf is applied to the front edge 58 (FIG. 7C) of the substrate 17, calf massage can be performed.

[About the second motion mode]
8 and 9 show a state in which the user 2 swings the knee support member 7 up and down by rotating the handle 25 in the left-right direction. FIG. 8B shows a state in which the handle 25 is rotated counterclockwise F1 from a neutral state (FIG. 8A) in which the handle 25 has a vertically projecting state, and FIG. The state is shown in which the handle 25 is rotated clockwise F2 from the neutral state (FIG. 8A).

  When the handle 25 in the vertically projecting state is rotated counterclockwise F1, the left leg 55a is moved from the state shown in FIG. 8A to the state shown in FIG. From the state shown in FIG. 9 (A), with the knee back portion 5a being received by the left knee receiving portion 6a, the left knee portion 3a is rotated around the axis of the left knee receiving portion 6a. 9 (B) is in a state of rolling outward as indicated by an arrow f1. 9A and 9B show a state in which an arbitrary point 63a on the outer peripheral surface 62a of the left knee 3a has moved to the lower left as indicated by an arrow f1. This rolling state is caused when the left leg 55a is twisted counterclockwise (outward) f1 by the action of gravity. Further, in the process of lifting the right knee portion 3b from the state shown in FIG. 8A to the state shown in FIG. 8B, the right knee back portion 5b was received by the right knee support portion 6b. In this state, the right knee 3b rolls inwardly on the right knee support 6b around the axis from the state shown in FIG. 9C, as indicated by an arrow f2 in FIG. 9D. It becomes a state. 9C and 9D show a state in which an arbitrary point 63b on the outer peripheral surface 62b of the right knee 3b has moved to the lower left as indicated by an arrow F2. This rolling state is caused when the right knee 3b is twisted to the left f2 as required by the action of gravity.

  When the handle 25 in the vertically projecting state is rotated clockwise F2 as shown in FIG. 8C, the reverse phenomenon occurs. That is, when the handle 25 in the vertically projecting state is rotated clockwise F2, in the process in which the right knee 3b is lowered from the state shown in FIG. 8A to the state shown in FIG. FIG. 9 (E) shows a state in which the right knee back portion 5b is received by the right knee receiving portion 6b and the right knee portion 3b is on the right knee receiving portion 6b around its axis. Thus, as shown by the arrow f3 in FIG. 9E and 9F show a state where an arbitrary point 63b on the outer peripheral surface 62b of the right knee 3b has moved to the lower right as indicated by an arrow f3. This rolling state is caused when the right knee 3b is twisted to the right f2 by the action of gravity. Further, in the process of lifting the left knee 3a from the state shown in FIG. 9G to the state shown in FIG. 9H, the left knee back 5a was received by the left knee support 6a. In this state, the left knee portion 3a rolls inwardly on the left knee support portion 6a around the axis from the state shown in FIG. 9G as shown by an arrow f4 in FIG. 9H. It becomes a state. 9G and 9H show a state in which an arbitrary point 63a on the outer peripheral surface portion 62a of the left knee 3a has moved to the lower right as indicated by an arrow f4. This rolling state is generated when the left knee 3a is twisted clockwise by the action of gravity.

  In this way, by repeating the turning operation of the handle 25 in the left-right direction, the left and right knee parts 3, 3 can alternately perform the outward rolling motion and the inward rolling motion. An effective massage action due to the twist of 3 or 3 is obtained. More specifically, when the left and right knee parts 3 and 3 roll, the parts of the left and right knee back parts 5 and 5 that are pressed and stimulated by the left and right knee support parts 6 and 6 are directed from the inside to the outside. Or changes from the outside toward the inside, so that the knee soles 5 and 5 are uniformly pressure-stimulated. When the exercise device 1 according to the present embodiment is used, the user can perform the vertical movement of the left and right knee support portions 6 and 6 by the turning operation of the handle 25 in the horizontal direction. It is possible to adjust the speed of the vertical movements of the left and right knee support parts 6 and 6 alternately, and to adjust the amplitude of the vertical movement as desired. It can also be changed inside. Further, the left and right knees 3 and 3 are not subjected to the downward movement of the handle 25 in the left and right direction, but resist the urging force generated when the coil spring 42 is bent in the left and right direction. If the left and right leg parts 3 and 3 are positively lowered downward, the pressure stimulus to the left and right knee back parts 5 and 5 can be strengthened, and the muscular strength of the quadriceps is more effective. To be strengthened.

  For these reasons, when the second movement pattern is repeated to rotate the handle 25 in the left-right direction, the frequency of pressing stimuli per unit time for the left and right knee back portions 5, 5 can be changed, The intensity of stimulation can be changed, and an effective massage action can be obtained. Further, with such effective massage, blood circulation promotion of the knee back portions 5 and 5 and expansion of the knee joint are achieved, and further, the muscle strength of the quadriceps can be strengthened through these exercises. Since these exercises can be performed with the left and right feet 59, 59 lifted from the floor surface 60, the exercise can be performed without undue weight on the left and right knees 3, 3. However, this exercise can relieve knee pain.

[About the third movement mode]
FIG. 10 shows a state where the user rotates the handle 25 in the front-rear direction to swing the knee support member 7 back and forth. 10A shows a state in which the handle 25 is rotated in the forward direction F3, and FIG. 10B shows a state in which the handle 25 is rotated in the rear direction F4.

  By rotating the handle 25 in the front-rear direction, the left and right knee support portions 6, 6 extend from the front side portion to the rear side portion of the left and right knee back portions 5, 5, and the left and right knee back portions. A pressure stimulus can be effectively applied over the full width in the left-right direction of each of 5 and 5, and by repeating this, the knee back portions 5 and 5 can be massaged evenly. At this time, by increasing the rotation angle toward the front of the handle 25, it is possible to apply a pressure stimulus to the front portions (portions close to the calves) of the left and right knee back portions 5 and 5, By increasing the rotation angle toward the rear of the handle 25, a pressure stimulus can be applied to the rear side portions (portions close to the bases of the thighs) of the left and right knee back portions 5, 5. . Then, the handle 25 is rotated forward at a larger angle, and the rotated state is maintained for a certain period of time, so that a pressure stimulus is continuously applied to the front side portions of the left and right knee back portions 5 and 5. The left and right knee soles 5 and 5 are effectively massaged by the synergistic effect of the above, and blood circulation promotion and expansion of the knee joint can be achieved in the left and right knee soles 5 and 5. It becomes.

  When the exercise apparatus 1 according to the present embodiment is used, the user himself / herself can perform the back and forth movement of the knee support member 7 by rotating the handle 25 in the front and rear direction. Therefore, the user can adjust the speed of the longitudinal movement of the handle 25 and can adjust the amplitude of the longitudinal movement as required, and these adjustments can be changed during the exercise. Further, the left and right leg portions 55 are not moved by the left and right knee portions 3 and 3 being moved by the rotation operation of the handle 25 in the front and rear direction. If the movement in the front-rear direction of 55 is positively and strongly performed, the muscular strength of the quadriceps is more effectively strengthened.

  By these, blood circulation promotion of the left and right knee back portions 5 and 5 and expansion of the knee joint are achieved. In particular, when the left and right knee back portions 5 and 5 are pressed and stimulated in front of the knee joint, It can be effectively expanded. In addition, the muscle strength of the quadriceps can be strengthened through these exercises. Since these exercises can be performed with the left and right feet 59 and 59 being lifted from the floor surface 60, the exercise can be performed without undue weight on the knee. However, this exercise can relieve knee pain.

[About the fourth movement mode]
When the exercise apparatus 1 according to the present embodiment is used, as described above, the knee support member 7 can perform the vertical swing motion and the forward / backward swing motion, and the knee support member 7 is the axis of the support portion 10. Since the support portion 10 is configured by a coil spring 42, the coil spring 42 can be elastically bent in any direction by 360 degrees by the rotation operation of the handle 25. it can.

  Therefore, when the exercise apparatus 1 is used, the left and right knee support portions 6 and 6 are swung so as to form a three-dimensional figure 8 as shown in FIG. Can be moved (hereinafter also referred to as “8-shaped swing movement”). The handle 25 is rotated in the order of A → B → C → D → A in FIG. This 8-shaped swing movement is such that, by turning the handle 25, the left and right knee support parts 6, 6 are made into a smaller 8-shaped swing movement, a larger 8-shaped swing movement, etc. Swing can be performed appropriately. When such an 8-shaped swing movement is used, the knee movement associated with the vertical movement of the left and right knee receiving sections 6 and 6 and the movement of the knee sections 3 and 3 associated with the longitudinal movement of the knee receiving member 7 are simultaneously performed. be able to. In addition, the left and right knee support portions 6 and 6 can be applied to the left and right knee back portions 5 and 5 in a direction inclined with respect to the left and right directions. Stimulation can be applied by changing the site to which the stimulation is applied and the strength of the pressing stimulus. In addition, when performing the figure-shaped swing movement, this movement is not left to the turning operation of the handle 25, but the left and right legs are moved while the user is lightly grasping the handle 25. If the force is applied and the strength is positively increased, the pressure stimulus to the left and right knee back portions 5 and 5 can be increased, and the muscular strength of the quadriceps can be strengthened.

  By these, the effective massage action of the left and right knee back parts 5 and 5, the effective massage action accompanying the rolling of the left and right knee parts 3 and 3, and the longitudinal movement of the left and right knee support parts 6 and 6 The effective massage action accompanying this is obtained, and the synergistic action of these can promote the blood circulation of the left and right knee back portions 5, 5 and expand the knee joint. However, these exercises can alleviate knee pain. And, since the user grips the handle 25 and performs the exercise associated with the figure-like swing movement, it stimulates not only the muscles of the left and right legs, but also the muscles of the arms and waists. It will also be a full body exercise.

  In the exercise apparatus 1 shown in FIG. 12, when the support portion 10 is configured using a coil spring 42, the lower insertion shaft 47 is inserted into the inclined holding hole 35b provided in the substrate 17, as shown in FIG. The upper insertion shaft 46 is inserted into the connection hole 33 of the handle 25, and the handle 25 protrudes upward toward the front. In the exercise apparatus 1, in the free state, the support portion 10 projects obliquely upward toward the front, and thus the left and right knee portions 3, 3 are placed on the left and right knee support portions 6, 6 in this free state. When placed, the weights of the left and right leg portions 55 and 55 cause the left and right knee support portions 6 and 6 to apply a pressure stimulus mainly to the front side portions of the left and right knee back portions 5 and 5, respectively. Also in this case, in the same manner as in the case where the handle 25 is in the vertical state, when the user rotates the handle 25 appropriately, the knee receiving member 7 is moved to the vertical swing motion or the forward / backward swing motion. In addition, it is possible to perform an eight-shaped swing movement or the like composed of these combinations, and to relieve knee pain in the same manner as described above.

[Other exercise modes]
The exercise device 1 having the above configuration can be used without holding the handle 25 by hand or with the handle 25 removed. 13 to 15 show a case where the knee receiving member 7 is caused to perform the up / down swing motion and the front / back swing motion only by moving the left and right legs 55, 55 with the handle 25 removed. .

  FIG. 13 shows an attachment generated when the left and right knee back portions 5 and 5 are placed on the left and right knee support portions 6 and 6 and the left and right leg portions 55 and 55 are bent in the left and right direction. A state is shown in which the knee support member 7 is caused to perform the up-and-down swing movement by alternately lowering against the force.

  14A shows a state in which the left and right knee soles 5 and 5 are placed on the left and right knee support portions 6 and 6, and the left and right lower leg portions 56 and 56 are hung in the same manner as shown in FIG. 7A. In this state, the knee support member 7 is moved backward by attracting the left and right knee portions 3, 3 in front of the user in resistance to the urging action when the coil spring 42 is bent. In this state, the left and right knee support portions 6 and 6 elastically press the left and right knee back portions 5 and 5 forward by the biasing action of the coil spring 42. FIG. 14B shows a state in which the left and right knee parts 3 and 3 are pushed forward to move the knee receiving member 7 forward. In this state, the left and right knee support portions 6 and 6 elastically press the left and right knee back portions 5 and 5 backward by the biasing action of the coil spring 42. By repeating the movement of moving the knee support member 7 back and forth in this manner, the left and right knee back portions 5 and 5 can be effectively massaged, and the knee joint can be effectively expanded. In addition, the movement of moving the left and right knees 3 and 3 to the front position and the rear position in this way is a movement that resists the urging force of the coil spring 42, so that the muscle strength of the quadriceps can be strengthened. Become. As a result, knee pain can be alleviated in the same manner as described above.

  The vertical swing motion and the forward / backward swing motion of the knee support member 7 can be similarly performed by the exercise equipment 1 that is inclined upward with the coil spring 42 facing forward. In this case, since the coil spring 42 is in a forward projecting inclined state, the left and right knee support portions 6 and 6 are connected to the left and right knee back portions 5 and 5 in a state where the knee support member 7 is rotated rearward. The pressing force that elastically presses the front portion of 5 toward the front can be made larger.

  Even in the exercise apparatus 1 that does not include the handle 25, as shown in FIG. 15, the length of the knee receiving member 7 is formed to be relatively long, and the outer gripping portion 65 is formed outside the knee receiving portions 6, 6. , 65, the user holds the left and right outer gripping portions 65, 65 with the left and right hands 57, 57, and causes the knee support member 7 to perform a three-dimensional eight-shaped swing movement. As in the exercise apparatus 1 that is provided with the handle 25, various pressing stimuli can be applied to the left and right knee back portions 5, 5.

  When the exercise apparatus 1 having the above-described configuration is used, the left and right knee back portions 5 and 5 are placed on the left and right knee support portions 6 and 6 while exercising with or without the handle 25. The left and right feet 59, 59 are lifted from the floor surface 60. Therefore, the user can freely change the stimulated part of the back of the knee with no weight applied to the left and right knees 3 and 3 regardless of the presence or absence of the knee pain disease. The strength can be changed freely. As a result, the user can perform whole body exercises such as legs, waists, shoulders, backs, and arms, or exercises close thereto.

  FIG. 16 shows one mode of whole body exercise. When the exercise apparatus 1 includes the handle 25, left and right knee support portions 6, 6 of the knee support member 7 in a horizontal state are left and right. The user holds the handle 25 in the vertical state with the left and right hands 57 and 57 while the knee back portions 5 and 5 are placed and the left and right lower leg portions 56 and 56 are hung, and the left and right knee portions 3 , 3 forcefully presses the left and right knee support portions 6 and 6 downward, and in this state, the user strongly twists the waist portion clockwise while holding the handle 25 in a vertical state. As a result, the user can strain the muscles of the upper body 66 including the left and right legs 55, 55 and the waist, and can perform effective whole body exercise.

  Other aspects of performing the whole body exercise with the exercise device 1 according to the present embodiment include, for example, changing the spring rigidity of the coil spring 42 of the support member 7 or moving the handle 25 up and down to the left and right knees. When the user adjusts the pressing force of the parts 3 and 3 himself or when the handle 25 is swung back and forth, the pulling force for pulling the left and right knee parts 3 and 3 toward the user side and the left and right knee parts 3 and 3 It is possible for the user to adjust the pushing force that pushes forward to the required level. Further, when the user turns the handle 25 by turning the handle 25, the user sets the force to be applied to the handle 25 as required, and the knee is adjusted as necessary to adjust the force. By changing the speed at which the receiving member 7 is swung up and down, the back-and-forth swing movement, the speed at which the figure-shaped swing movement is performed, and the like, the user can exercise the whole body with an appropriate load without putting weight on the knee. it can.

  For example, whole body exercises such as stepping exercises, bicycle rowing exercises, walking exercises, fast walking exercises, and running exercises can be performed. These exercises can be effectively performed even by a user with knee pain or a user without knee pain. In addition, the exercise apparatus 1 can be used from children to adults. Since the elderly can safely exercise without fear of falling, the exercise apparatus 1 is preferable to be used in, for example, a nursing facility in addition to a general home.
