Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a leg correction device. Background Art

[0002] During the physical development period, malnutrition, related diseases, or long-term bad postures and incorrect force application habits can cause bone displacement, thus forming X-shaped legs or O-shaped legs. For example, in Japan, kneeling is quite common in daily life. When kneeling, the gluteus maximus will expand outward, and at the same time, the greater trochanter of the bone will also shift accordingly. Over time, the gap between the two knees becomes too large, resulting in O-shaped legs. Existing technologies usually use straps and clamps for correction. Although such methods also have certain effects, they require more than 2 hours of cooperation every day. The disadvantage of this method is that the user cannot move during the use time, and the limbs are oppressed by the device for a long time, resulting in unsmooth blood flow and discomfort such as limb numbness. Therefore, it is necessary to design a leg correction device to reduce the harm caused to the user's limbs during the leg correction process. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to provide a leg correction device that is not easy to cause harm to the user's limbs during the correction process.

[0004] To solve the above technical problem, the technical solution adopted by the utility model is: a leg correction device, including a base, an elastic member, and two foot support plates. The two foot support plates are symmetrically arranged. One end of each of the two foot support plates close to the user's heel is rotatably connected to the base. The elastic member is installed on the base and is used to drive the two foot support plates to rotate and approach each other.

[0005] Further, the elastic member is a spring, a spring sheet, or a spring pad.

[0006] Further, the number of the elastic members corresponds to the number of the foot support plates one by one, and both ends of the elastic member respectively abut against the foot support plate and the base.

[0007] Further, an arc-shaped receiving groove is formed on the base, a sliding block is arranged on the foot support plate, the sliding block is slidably matched with the receiving groove, and the elastic member is arranged in the receiving groove.

[0008] Further, a detachable arch adaptor pad is arranged on the foot support plate.

[0009] Further, a plurality of rollers are arranged on one side of the foot support plate close to the base.

[0010] Further, an arc-shaped limiting step is provided on the base, and a limiting block is provided on the foot support plate, and the limiting block is slidably abutted against the limiting step.

[0011] Further, the base includes a left bottom plate, a connecting plate and a right bottom plate. The two sides of the connecting plate are respectively rotatably connected to the left bottom plate and the right bottom plate, and one foot support plate is respectively provided on the left bottom plate and the right bottom plate.

[0012] Further, a bearing is provided between the foot support plate and the base.

[0013] Further, an anti-slip pad is provided on the bottom surface of the base.

[0014] The beneficial effect of the present utility model is that: during the use of this leg type corrector, there is no need to cause compression on the limbs. The user only needs to place the feet on the two foot support plates, and then make the feet rotate outward with the heels as the center, and the front ends of the two feet respectively overcome the reaction force of the elastic members. In this way, the tibia and femur of the two feet can follow the rotation, and the lesser trochanter and the greater trochanter jointly drive the gluteus maximus and the piriformis muscles to twist towards the central axis of the human body, thereby changing the human muscles and bones and achieving the effect of correcting O-shaped legs or X-shaped legs.

[0027] To describe in detail the technical content, achieved purpose and effects of the present utility model, the following is described in conjunction with the implementation modes and with reference to the drawings.

[0028] Please refer to Figures 1 to 5 , the leg correction instrument, including a base 1, an elastic member 2 and two foot support plates 3. The two foot support plates 3 are symmetrically arranged.

The elastic member 2 is used to drive the two foot support plates 3 to rotate and approach each other.

[0029] As can be seen from the above description, the beneficial effect of the present utility model is that: during the use of this leg correction instrument, there is no need to cause compression on the limbs. The user only needs to place the feet on the two foot support plates 3, and then make the feet rotate outward with the heels as the center, and the front ends of the two feet respectively overcome the reaction force of the elastic member 2. In this way, the tibia and femur of the two feet can follow the rotation, and the lesser trochanter and the greater trochanter jointly drive the gluteus maximus and the piriformis muscles to twist towards the central axis of the human body, thereby changing the human muscles and bones and achieving the effect of correcting O-shaped legs or X-shaped legs.

[0030] Further, the elastic member 2 is a spring, a spring sheet or a spring pad.

[0031] As can be seen from the above description, the type of the elastic member 2 can be selected according to the actual use needs or production conditions.

[0032] Further, the number of the elastic members 2 corresponds to the number of the foot support plates 3 one by one. Two ends of the elastic member 2 respectively abut against the foot support plate 3 and the base 1.

[0033] As can be seen from the above description, using two elastic members 2 to respectively abut against the two foot support plates 3 can reduce the strength requirement for the elastic member 2.

[0034] Further, an arc-shaped receiving groove 11 is formed on the base 1. A slide block 31 is arranged on the foot support plate 3. The slide block 31 is slidably matched with the receiving groove 11. The elastic member 2 is arranged in the receiving groove 11.

[0035] As described above, setting the arc-shaped receiving groove 11 can guide the movement process of the foot support plate 3, and the receiving groove 11 can also limit the elastic member 2.

[0036] Furthermore, a detachable arch adaptor pad 4 is provided on the foot support plate 3.

[0037] As described above, setting the arch adaptor pad 4 can improve the use comfort, and can also improve the sole bones of users with flat feet or abnormal ankle bones.

[0038] Furthermore, a plurality of rollers 5 are provided on the surface of the foot support plate 3 close to the base 1.

[0039] As described above, setting the rollers 5 can reduce the wear of the foot support plate 3 and the base 1.

[0040] Furthermore, an arc-shaped limiting step 15 is provided on the base 1, and a limiting block 32 is provided on the foot support plate 3, and the limiting block 32 is slidably abutted against the limiting step 15.

[0041] As described above, the limiting block 32 abutting against the limiting step 15 can help the foot support plate 3 bear the force perpendicular to the rotation axis, which is beneficial to extending the service life of the rotational connection structure between the foot support plate 3 and the base 1.

[0042] Furthermore, the base 1 includes a left base plate 12, a connecting plate 13 and a right base plate 14. The two sides of the connecting plate 13 are respectively rotatably connected to the left base plate 12 and the right base plate 14, and one of the foot support plates 3 is provided on each of the left base plate 12 and the right base plate 14.

[0043] As described above, when the leg type corrector is idle, the base 1 can be folded up, which is convenient for storage and transportation.

[0044] Furthermore, a bearing 6 is provided between the foot support plate 3 and the base 1.

[0045] As described above, setting the bearing 6 can make the rotation process of the foot support plate 3 smoother and reduce the wear of the foot support plate 3 and the base 1.

[0046] Furthermore, an anti-slip pad 33 is provided on the bottom surface of the base 1.

[0047] As described above, setting the anti-slip pad 33 can increase the friction between the base 1 and the ground, and prevent the leg type corrector from accidentally slipping during use, causing the user to fall.

[0048] Please refer to Figures 1 to 5, Embodiment 1 of the present utility model is: a leg correction device, which includes a base 1, an elastic member 2, and two foot support plates 3. The two foot support plates 3 are symmetrically arranged. The ends of the two foot support plates 3 close to the user's heels are respectively rotatably connected to the top surface of the base 1. The elastic member 2 is installed on the base 1, and the elastic member 2 is used to drive the two foot support plates 3 to rotate and approach each other.

[0049] Specifically, the foot support plate 3 includes a support plate main body and a limit baffle. A cylindrical boss is provided at the bottom surface of the support plate main body near the user's heel. An assembly hole matching the cylindrical boss is provided on the base 1. The cylindrical boss of the support plate main body is inserted into the assembly hole from top to bottom. The limit baffle is arranged below the base 1 and is connected to the cylindrical boss of the support plate main body by screws, so that the foot support plate 3 is rotatably connected to the base 1. The elastic member 2 is a spring. The number of the elastic members 2 corresponds to the number of the foot support plates 3 one by one. The two ends of the elastic member 2 respectively abut against the foot support plate 3 and the base 1. The elastic member 2 provides a reaction force for the two foot support plates 3 to rotate outward. The greater the angle through which the foot support plate 3 rotates, the greater the reaction force, thus playing an exercise role. In other embodiments, the two ends of the elastic member 2 are respectively connected to the base 1 and the foot support plate 3, or the number of the elastic members 2 is set to one, and the two ends of the elastic member 2 are respectively connected to the two foot support plates 3, which is also feasible; the elastic member 2 can be set as a spring piece or a spring pad.

[0050] As Figure 1 and Figure 2 shown, the base 1 includes a left bottom plate 12, a connecting plate 13, and a right bottom plate 14. The two sides of the connecting plate 13 are respectively rotatably connected to the left bottom plate 12 and the right bottom plate 14. One foot support plate 3 is provided on each of the left bottom plate 12 and the right bottom plate 14. Specifically, the left bottom plate 12 and the right bottom plate 14 are symmetrically arranged with the connecting plate 13 as the center, and the two foot support plates 3 are symmetrically arranged with the connecting plate 13 as the center. It is easy to understand that when the leg correction device is idle, the base 1 can be folded up, which is convenient for storage and transportation.

[0051] As Figure 5 shown, an arc-shaped receiving groove 11 is formed on the base 1. A slider 31 is provided on the bottom surface of the foot support plate 3. The slider 31 is slidably matched with the receiving groove 11. The elastic member 2 is arranged in the receiving groove 11, and the two ends of the elastic member 2 respectively abut against the outer side surface of the slider 31 and the end surface of the receiving groove 11.

[0052] As Figure 1 , Figure 4 and Figure 5As shown, an arc-shaped limiting step 15 is provided on the base 1. The limiting step 15 has a contact surface facing the end where the foot support plate 3 is connected to the base 1. A limiting block 32 is provided on the foot support plate 3, and the limiting block 32 can slide and contact the contact surface of the limiting step 15. It is easy to understand that the limiting block 32 contacting the limiting step 15 can help the foot support plate 3 bear the force perpendicular to the rotation axis, which is beneficial to extending the service life of the rotational connection structure between the foot support plate 3 and the base 1.

[0053] As Figure 5 shown, in order to reduce the friction between the foot support plate 3 and the base 1, a bearing 6 is provided between the foot support plate 3 and the base 1. As Figure 4 shown, a plurality of rollers 5 are provided on the surface of the foot support plate 3 close to the base 1, and the rollers 5 can reduce the wear of the foot support plate 3 and the base 1.

[0054] As Figure 1 shown, a detachable arch adaptor pad 4 is provided on the foot support plate 3. Specifically, a limiting groove is provided on the foot support plate 3, and the arch adaptor pad 4 is placed in the limiting groove. The arch adaptor pad 4 is used to adapt to the shape of the patient's arch, which can improve the use comfort and can improve the sole bones of users with flat feet or abnormal ankle bones.

[0055] As Figure 3 shown, in order to prevent the leg orthosis from accidentally slipping during use and causing the user to fall, an anti-slip pad 33 is provided on the bottom surface of the base 1. Specifically, the base 1 is in a rounded rectangle shape, and eight anti-slip pads 33 are provided on the bottom surface of the base 1. Four of the anti-slip pads 33 are provided at the four corners of the base 1, two anti-slip pads 33 are provided corresponding to the user's toes, and two anti-slip pads 33 are provided corresponding to the user's heels. The two anti-slip pads 33 corresponding to the user's heels respectively cover the bottom openings of the two assembly holes of the base 1.

[0056] In summary, the leg correction device provided by the present utility model does not cause compression to the limbs during use. The user only needs to place the feet on the two foot support plates, and then rotate the front ends of the two feet outward around the heels respectively to overcome the reaction force of the elastic members. In this way, the tibias and femurs of the two feet can follow the rotation, and the lesser trochanter and the greater trochanter jointly drive the gluteus maximus and the piriformis muscles to twist towards the central axis of the human body, thereby changing the human muscles and bones and achieving the effect of correcting O-shaped legs or X-shaped legs. The arc-shaped receiving groove can guide the movement process of the foot support plate, and can also limit the elastic member. The arch adaptor pad can improve the comfort of use and can also improve the sole bones of users with flat feet or abnormal ankle bones. The rollers can reduce the wear of the foot support plate and the base. The limiting block abuts against the limiting step, which can help the foot support plate bear the force perpendicular to the rotating shaft, and is beneficial to extending the service life of the rotating connection structure between the foot support plate and the base. The base can be folded up, which is convenient for storing and transporting the leg correction device. The bearing can make the rotation process of the foot support plate smoother and reduce the wear of the foot support plate and the base. The anti-slip pad can increase the friction between the base and the ground, and prevent the leg correction device from accidentally slipping during use and causing the user to fall.
