Description

[Technical field]

[0001] The present invention relates to an inexpensive health equipment and health equipment set that simultaneously performs knee and hip joint traction and joint rocking exercises, and improves and prevents symptoms of knee and hip joint diseases through the synergistic effects of these exercises, and can be easily used in daily life such as watching television, reading, eating, sleeping, etc. [Background technology]

[0002] It is known that traction of the lower limbs has a certain therapeutic effect on movement disorders such as osteoarthritis of the knee and osteoarthritis of the hip (Non-Patent Documents 1 to 4), and the symptom-improving effect of bending and straightening exercises of the knee joint is described in Non-Patent Document 5. Patent Documents 1 and 2 disclose devices for treating the above-mentioned movement disorders. In addition, devices that aim to obtain not only the therapeutic effect of the lower limbs but also the effect of training and massage are also disclosed. For example, Patent Document 3 discloses a knee exercise tool in which a user sits on a chair with a rectangular frame upright and swings the left and right knees placed on the top of the frame up and down, causing the frame to swing back and forth from the installation point, thereby performing knee flexion and extension exercises. In addition, Patent Document 4 discloses a health device in which, when a user lies on his / her back and places the backs of the left and right knees on the support parts and slides the toes backward, the support parts connected to the swinging arms move toward the toes, and the thighs and lumbar spine are pulled diagonally upward. The inventors of the present application have developed and obtained a patent for a lower limb traction device that can provide large traction force, is easy to adjust the traction force and to carry, is not limited to specific locations for use, and is inexpensive (Patent Document 5).

[0005] However, the technologies disclosed in the above Patent Documents 1 and 2 have the following problems: In both cases, the user wears the device on the lower limbs while sitting or lying down on the floor, which causes problems that the device is large and takes up space, that it can only be used in clean places where it is possible to sit or lie down, and that it is difficult to obtain sufficient traction force because it is pulled with the arm, and that it is difficult for the user to adjust the traction force. The technology disclosed in Patent Document 3 achieves the effect of bending and straightening the knee joint by swinging the toes back and forth during use, but has the problem that it cannot swing in any direction other than back and forth, and cannot swing left and right, which is effective for the hip joint.

[0006] The technology disclosed in Patent Document 4 also pulls the thigh and lumbar region diagonally upward by moving the knee forward, and has the problem of not being able to provide effective left-right swinging of the hip joint. Furthermore, in the techniques disclosed in Patent Documents 3 and 4, the orientation of the device during use is fixed, which poses the problem that the user needs to adjust the orientation of the device to match the orientation of their body, which is troublesome. In addition, the technology disclosed in the above Patent Document 5 traction one leg, and since it is used while standing with one leg fixed, there is a risk of falling and injuring oneself, it is difficult to use for people with weak legs and hips because it results in an unstable posture, it is not possible to simultaneously bend and straighten the knee joint, and it is difficult to perform traction exercises while watching television, reading, etc.

[0007] In consideration of the above problems, the present invention aims to provide an inexpensive health equipment and health equipment set that simultaneously performs knee and hip joint traction and joint rocking exercises, and improves and prevents the symptoms of knee and hip joint diseases through the synergistic effect of these exercises, and can be easily used in daily life such as watching television, reading, eating, sleeping, etc. [Means for solving the problem]

[0008] The fitness device of the present invention is a fitness device that is used standing on a horizontal surface and tilted forward, and is equipped with a support portion located at the top for placing only one of the left or right calves, a contact portion located at the bottom and in contact with the surface, and a support portion connecting the support portion and the contact portion. In addition, the placement portion is characterized in that, when it is upright, it has a circular shape in a plan view. In addition, the contact portion has a circular horizontal cross-sectional shape when held upright. The contact portion is also characterized in that it has a downwardly convex shape. The contact portion may further include a weight. The contact portion is also characterized by having a concentric slit extending from the lower surface of the contact portion in the longitudinal direction. The support pillar may be divided into a plurality of blocks, and the plurality of blocks may be fitted together and stacked.

[0009] The fitness tool set of the present invention comprises the fitness tool described above, and a receiving tray that is disposed between the flat surface and the contact portion when the fitness tool is upright. The lower surface of the contact portion and the upper surface of the receiving tray are detachable by magnetic force. Effect of the Invention

[0010] According to the health equipment of the present invention, the knee joint and hip joint are pulled by tilting the health equipment forward while one of the calves is placed on the support. In addition, the knee joint and hip joint can be simultaneously rocked while being pulled without using muscle strength. These synergistic effects can improve and prevent the symptoms of knee joint and hip joint diseases. In addition, the health equipment can be easily used by users in their daily lives, and the structure is simple, so that the health equipment can be manufactured inexpensively. By making the resting portion circular in plan view, the user can place his / her calf on the resting portion without worrying about the orientation of the resting portion, thereby improving convenience during use. By making the horizontal cross-sectional shape of the contact portion circular, the user does not need to worry about the orientation of the contact portion, thereby improving convenience during use.

[0011] In addition, by making the contact portion convex downward, the user can smoothly rock the fitness device not only in the front-to-back direction, but also in the left-to-right and diagonal directions, thereby generating rocking movement of the hip joint in a variety of directions, and more effectively improving and preventing the symptoms of knee and hip joint diseases. By providing a weight at the contact part, the fitness equipment can automatically return to an upright state from a significantly tilted state, so that the fitness equipment will not fall over while the user is adjusting the position on which the calf is placed or when the user removes the calf after use, improving convenience. By providing the contact portion with a slit along the longitudinal direction of the device, it is possible to prevent the position of the contact portion from shifting when the fitness device is swung in an inclined position, as the pleat portion formed by the slit in the contact portion is inclined and comes into contact with a flat surface. In addition, the support structure is made up of multiple blocks that fit together and are stacked, allowing the user to adjust the overall height of the fitness equipment by rearranging the blocks (adding or removing blocks) according to their physique and the place of use.

[0012] According to the fitness equipment set of the present invention, by placing a receiving tray with a raised edge around the peripheral edge between the plane and the contact portion, the raised portion of the receiving tray can prevent the contact portion from shifting due to the swinging of the fitness equipment. In addition, the raised portion on the peripheral edge of the tray of the fitness equipment equipped with a weight acts as a stopper for the automatic return to an upright position and stops the equipment in an inclined state. Therefore, when the user temporarily stops using the fitness equipment and then resumes it, the equipment can be started from the inclined state used last time, which increases convenience. By making the underside of the contact portion and the upper surface of the tray detachable by magnetic force, the main body and the tray can be integrated when moving or storing the fitness equipment set, thereby increasing convenience.

[0014] [First embodiment] A first embodiment of the fitness device of the present invention will be described. 1 and 2, the fitness tool 1 of this embodiment is used in a state where it stands on a horizontal plane 100 and is tilted forward. Examples of the plane 100 include, but are not limited to, a floor surface, a mat laid on a floor surface, a bed, and the underside of a step at an entrance or the like.

[0015] The fitness tool 1 includes a placement portion 10 , a contact portion 20 and a support portion 30 . The placement portion 10 is located at the top of the fitness device 1 in an upright position. Only one of the left or right calves of a user in a seated position (e.g., sitting on a chair) is placed on the placement portion 10. In other words, the upper surface of the placement portion 10 only needs to have a maximum width that allows one of the user's calves to be placed on it, and does not need to be wide enough to allow both calves to be placed on it at the same time. In this embodiment, the shape of the mounting portion 10 is circular in plan view. Although the shape of the mounting portion 10 may be polygonal, it is preferably circular in plan view. As shown in Fig. 3(a), if the shape in plan view is a triangle, the corners will be acute, so the corners will dig into the calf, and there is a risk of pain during use. In addition, by making it circular in plan view, the user can place the calf on the mounting portion 10 without worrying about the orientation, so the convenience during use can be improved. When the mounting portion 10 is circular in plan view, the appropriate value of its diameter is 10 to 25 cm, and a shape with chamfered rounded edges at the circumferential portion is desirable because the rocking motion can be performed smoothly.

[0016] The contact portion 20 is located at the lowermost part of the health device 1 in an upright state. That is, the health device 1 contacts the flat surface 100 at the contact portion 20. Regarding the shape of the contact portion 20, in this embodiment, the horizontal cross-sectional shape is circular and convex downward. The horizontal cross-sectional shape of the contact portion 20 may be polygonal, but it is preferably circular. As shown in Fig. 3(a), if the horizontal cross-sectional shape is a shape with sides such as a triangle, there will be a case where it contacts the flat surface 100 with the sides, and as will be described later, a problem will occur that smooth rocking cannot be performed when the health device 1 is rocked on the flat surface 100. In addition, by making the horizontal cross-sectional shape circular, the user can use the health device 1 without worrying about the orientation of the contact portion 20, so the convenience during use can be improved. As shown in Fig. 3(b), the contact portion 20 may be a flat surface 20a that does not protrude downward.

[0017] The support portion 30 is a member that connects the mounting portion 10 and the contact portion 20. In this embodiment, the diameters of the mounting portion 10, the support portion 30, and the contact portion 20 are made the same. As a result, the strength of the support portion 30 is increased, so even when a large load is applied to the mounting portion 10 from the calf, the possibility of the support portion 30 breaking or buckling can be suppressed. According to the health device 1 of this embodiment, the mounting portion 10, the support portion 30, and the contact portion 20 can be integrally formed, and the manufacturing cost can be suppressed. The horizontal cross-sectional shape of the support part 30 may be such that the diameter is larger in the middle compared to the upper and lower ends as shown in Fig. 4(a). Conversely, the support part 30 may be constricted in the center as long as the necessary strength of the support part 30 is ensured. The material of the fitness tool 1 is not particularly limited, and may be polystyrene foam, polyurethane foam, plastic, wood, metal, or paper. It may also have a cross-section filled structure or a hollow structure. The mounting part 10, the support part 30, and the contact part 20 may be manufactured integrally, or the mounting part 10 and the support part 30 may be manufactured separately and then joined by screws, adhesives, or the like. The overall height of the fitness device 1 should be approximately the same as the seat height of the chair when the user is sitting on it, with a suitable value being 35 to 55 cm. When the user is lying on a bed or the like when using the fitness device 1, the suitable value is 30 to 15 cm. 4(b), the support 30 may be configured by stacking a plurality of blocks 30a-30d, each having a convex portion on the upper surface and a concave portion on the lower surface, which are fitted together. The user can adjust the overall height of the fitness device 1 by rearranging the blocks 30a-30d (by adding or removing blocks) according to their physique and the place of use.

[0018] A method of using the fitness tool 1 will now be described. As shown in Fig. 1, a user sits on a chair and places either the left or right calf (left leg 102 in Fig. 1) on the placement section 10 with the fitness tool 1 tilted forward in an upright position. If the angle between the longitudinal center line of the fitness tool 1 and the vertical line is the inclination angle θ, then the optimal inclination angle θ is 5 to 40°. In this state, the left leg 102 is suspended in the air, and the right leg lands on the flat surface 100. The following description will be given of the case where the left calf is placed on the placement section 10, but the same action of switching the left and right sides is performed when the right calf is placed on the placement section 10, and the same effect can be obtained. As shown in Fig. 5, the vertical load W (weight of the lower limb) applied from the calf to the support part 10 can be broken down into the longitudinal direction of the fitness tool 1 and the direction along the tibia 101, and a traction force is generated on the knee joint 103 by a load component force W1 acting in the direction along the tibia 101. This traction force also acts directly on the hip joint. Specifically, when the inclination angle θ is 30°, the load component force W1 is half the magnitude of the load W.

[0019] 6, the calf can be regarded as the fulcrum of the lever (black triangle in the figure), the tibia 101 as the bar of the lever, the foot 102 as the force point, and the knee joint 103 as the point of action. At this time, a large force F is generated diagonally upward at the knee joint 103, and a parallelogram vector decomposition of this force generates a force F1 that pulls the knee joint 103 in the extension direction of the femur. W1 and F1 combine to exert a sufficient pulling force on the knee joint, and this pulling force also acts directly on the hip joint. In this state, the weight of each part of the lower leg is balanced with the support part 10 and the contact part 20 as the fulcrum, and the lower leg is stable and stationary with the user relaxed, as shown in Figure 7. When bending and straightening the knee from this stationary state, it can be moved (rocked) with little force due to the seesaw principle, and the hip joint can be moved at the same time. Similarly, the movement of opening and closing the hip joint from side to side, as shown by the thick arrow in Figure 7, can be performed with little force. In other words, it has the same effect as underwater exercise (exercise in zero gravity), which is known to be effective in treating osteoarthritis.

[0020] In this way, the fitness device 1 can simultaneously perform rocking exercises of the knee joint and hip joint without using muscle force while the knee joint and hip joint are in traction. The greatest feature of the present invention is that it allows for this rocking exercise without muscle force, which was not possible with the prior art. Although the fitness device 1 is designed for one leg only, if you want to exercise both legs at the same time, you can use two fitness devices 1 side by side. In this case, the left and right legs can be swung independently, which was not possible with the prior art. When the inclination angle θ is large, the contact portion 20 is not fixed to the plane 100, and a problem occurs in that the contact portion 20 gradually shifts backward as the contact portion 20 swings. A method for solving this problem will be described later.

[0021] [Second embodiment] A second embodiment of the fitness tool of the present invention will be described. The same components as those in the first embodiment will be designated by the same reference numerals and the description thereof will be omitted. As shown in Fig. 8, the fitness tool 2 of this embodiment is characterized in that the mounting part 11 is a thin disk-like shape that is circular when viewed from above. Specifically, the contact part 21 and the support part 31 are both circular with the same diameter in horizontal cross section, and the diameter of the mounting part 11 is larger than the diameters of the horizontal cross sections of the support part 31 and the contact part 21. In other words, the fitness tool 2 is T-shaped when viewed from the front. By making the fitness tool 2 T-shaped when viewed from the front, it can be manufactured by combining general-purpose flat plate material, rod material, and pipe material, making it inexpensive. In addition, it is easy to make the structure so that the user can disassemble and assemble it, and it is possible to realize a tool that can be disassembled and made small for travel.

[0022] [Third embodiment] A third embodiment of the fitness tool 1 of the present invention will be described. The same components as those in the above-described embodiments will be designated by the same reference numerals and the description thereof will be omitted. As shown in Figures 9(a) and (b), the fitness tool 3 of this embodiment is characterized in that it has multiple concentric slits 22 along the longitudinal direction from the lower surface of the contact part 21, which has a downwardly convex shape. By providing the slits 22, when the fitness tool 3 is in a tilted use state, the fold part 22a formed by the slits 22 is tilted and contacts the flat surface 100 as shown in Figure 9(c), so that it is easy to come off in the direction of the arrow A in Figure 9(c) but is difficult to come off in the opposite direction of the arrow B (leading and trailing effect). This effect makes it possible to prevent the contact part 21 from coming off in the direction of the arrow B when the fitness tool 3 is swung.

[0023] [Fourth embodiment] A fourth embodiment of the fitness tool of the present invention will be described. The same components as those in the above-described embodiments will be designated by the same reference numerals and the description thereof will be omitted. As shown in FIG. 10(a), the fitness tool 4 of this embodiment is characterized by having a weight 23 on the contact part 20. By providing the weight 23, the fitness tool 1 can be automatically restored from a greatly inclined state to an upright state as shown in FIG. 10(b), so that the fitness tool 1 does not fall over during use and convenience can be improved. The weight 23 may be attached to the lower surface of the contact part 20, or may be embedded inside the contact part 20. By making the contact part 20 into a downwardly convex shape, the automatic restoration effect can be more easily obtained. In addition, by reducing the weight of the placement part 10 and the support part 30, the automatic restoration effect can be more easily obtained. As shown in FIG. 10(c), the weight 23 may be attached to the fitness tool 3 having the slit 22 shown in the third embodiment.

[0024] [Fifth embodiment] A fifth embodiment of the fitness tool of the present invention will be described. The same components as those in the above-described embodiments will be designated by the same reference numerals and the description thereof will be omitted. As shown in FIG. 11, the fitness tool 5 of this embodiment is characterized in that it is used in a supine position. Compared with the fitness tools 1 to 4 used in a sitting position shown in the first to fourth embodiments, the fitness tool 5 used in a supine position may be small and low in overall height. The optimum overall height of the fitness tool 5 is 15 to 30 cm. The user places the calf of either the left or right leg (left leg 102 in FIG. 11) on the placement part 10, and with the left leg 102 raised, pulls the left thigh slightly backward, and then pushes the left thigh forward. In this way, the user swings the fitness tool 5 with the left leg 102 to repeatedly bend and straighten the left knee joint 103. In this form, a traction force acts on the knee joint 103 and hip joint as in the fitness tools 1 to 4.

[0025] [First embodiment] A first embodiment of the fitness tool set of the present invention will be described. The same components as those in the above-described fitness tool embodiments will be designated by the same reference numerals and their description will be omitted. As shown in Fig. 12, the fitness tool set 40 of this embodiment is characterized by including the fitness tool 1 and a disk-shaped tray 50. The disk-shaped tray 50 has a raised edge 51 and is inclined outward from the top of the raised edge to the outer periphery, and is disposed between the plane 100 and the contact part 20 when the fitness tool 1 is upright. As shown in Fig. 13(a), if the tray 50 is not used, the position of the contact part 20 on the plane 100 will gradually shift while the fitness tool 1 is rocked, and the optimal positional relationship between the tool and the user's body cannot be maintained, and the fitness tool 1 will eventually fall over.

[0026] Therefore, when the fitness tool 1 is placed on the tray 50 as shown in FIG. 13(b), the contact portion 20 moves little by little across the upper surface of the tray 50 while the fitness tool 1 is being rocked, but stops moving when it comes into contact with the raised edge 51 of the tray 50. By appropriately setting the diameter of the tray 50 and the height and shape of the raised edge 51, it is possible to prevent the contact part 20 from climbing over the edge 51 and going outside the tray 50, and smooth rocking is not impeded. The tray 50 itself does not rock, and the maximum static friction force is maintained between the bottom surface of the tray 50 and the flat surface 100, so the tray 50 does not come off. By using the tray 50, the fitness tool 1 can be rocked stably while being fixed on the tray 50. It is desirable that the bottom surface of the tray 50 has a large coefficient of friction with the flat surface 100, and that the material and surface shape are non-slip. Furthermore, in a fitness device equipped with weight 23, when the calf is removed from mounting portion 10 with contact portion 20 in contact with the raised portion of edge 51 of tray 50, the raised portion acts as a stopper for automatic return to upright position, and fitness device 1 stops in an inclined position (solid line state in FIG. 13(b)). When the user temporarily stops using fitness device 1 and then resumes it, fitness device 1 can start from the previously used inclined position, eliminating the need for inclination readjustment and increasing convenience. Furthermore, by forming the tray 50 in a disk shape, the user can use the fitness tool set 40 without having to worry about the orientation of the tray 50, thereby improving convenience during use. From a safety standpoint, it is desirable to make the top of the raised edge 51 of the tray 50 rounded to prevent injury if stepped on. From the same safety standpoint, it is desirable for the tray 50 to be made of a material that is difficult to break and, even if it does break, does not leave sharp cracks, such as soft plastic or pressed metal plate.

[0027] As shown in FIG. 14, even when the fitness tool 2 and the receiving tray 50 shown in the second embodiment are combined, the fitness tool 2 can be prevented from shifting and can be stably swung. As shown in FIG. 15, even when a fitness tool 4 having weights 23 and slits 22 as shown in the fourth embodiment is combined with a tray 50, the fitness tool 4 can be stably swung while being fixed on the tray 50, and the fitness tool 4 can maintain the inclination of the previous use state.

[0028] [Second embodiment] A second embodiment of the fitness tool set of the present invention will be described. The same components as those in the above-described embodiments will be designated by the same reference numerals and the description thereof will be omitted. As shown in Fig. 16, the fitness tool set 60 of this embodiment is characterized in that the lower surface of the contact portion 20 and the upper surface of the receiving tray 50 can be attached and detached by magnetic force. Specifically, a magnet 70 is provided on the upper surface of the receiving tray 50, and the weight 23 can be magnetically attached to the magnet 70 by using a magnetic material (ferromagnetic material) such as iron or a magnet as the material for the weight 23. This allows the fitness tool 1 to be integrated in an upright state on the receiving tray 50, improving convenience during transportation and storage. When using the fitness tool 1, the magnetic attachment of the weight 23 can be released by tilting the fitness tool 1. The same effect can be obtained by using a magnet for weight 23 and a magnetic body (ferromagnetic body) for receiving tray 50. As shown in FIG. 17, the fitness tool 2, the magnetic piece 80, the tray 50 and the magnet 70 shown in the second embodiment can be combined to obtain the same effect. [Industrial Applicability]
