Description

Technical Field

[0001] The invention belongs to the technical field of foot correction, and in particular relates to a brace for correcting foot deformities in children. Background Art

[0002] In order to correct children's walking gait and reduce the pain of walking, some children with clubfoot need to wear foot deformity correction braces. The foot deformity correction braces provide stable support and appropriate pressure for children's feet, and then gradually correct the foot deformity and restore the foot to normal.

[0003] Since the foot skeleton of children is relatively soft, special massage techniques can be used to assist correction when using foot deformity correction braces for correction. However, since the current foot deformity correction braces include corrective shoes and leg guards, and the two are fixedly connected, the corrective shoes and leg guards need to be removed together during massage, and the whole process is relatively cumbersome. At the same time, the two corrective shoes of some corrective braces are fixedly connected by correction plates. This method will deprive children of their ability to move when wearing them, and will greatly increase children's aversion to corrective shoes when they are unable to move. In addition, since foot deformity correction braces need to provide appropriate pressure on children's feet, in the early stages of children's wearing, since children are not used to wearing corrective shoes, the squeezing force will continue to squeeze children's feet after wearing them for a long time, causing discomfort and even pain in children's feet, making children gradually resist wearing corrective shoes, which will greatly affect children's wearing comfort.

The annular plate 15 is located between the circular plate 17 and the rope 13. The second spring 19 is sleeved on the two ends of the rotating rod 18, and the two ends of the second spring 19 are respectively fixedly connected to the annular plate 15 and the circular plate 17. A plurality of first springs 12 are symmetrically connected to the two ends of the sliding plate 4 at equal intervals. The other end of the first spring 12 is fixedly connected to the inner wall of the sliding hole 28. Cylinders 23 are symmetrically installed at the middle of both sides of the corrective shoe 10. The end of the screw 11 is embedded in the interior of the cylinder 23 and is threadedly connected to the cylinder 23.

[0026] According to the above technical solution, when in use, the corrective shoe 10 is moved to the bottom of the leg guard 1, and the connecting plate 7 is rotated to rotate on the connecting shaft 21, so that the plug block 5 is arranged on the connecting plate 7 through the through hole, and the corrective shoe 10 is connected to the bottom of the leg guard 1 by the engagement connection between the connecting plate 7 and the plug block 5, and then the screw rods 11 on both sides of the leg frame 6 are pulled, and the screw rods 11 pull the rope 13 while moving, driving the rotating rod 18 to start rotating after squeezing the second spring 19, so that the rope 13 gradually extends to Outside, after the screw 11 is aligned with the cylinder 23, the screw 11 is driven to be inserted into the cylinder 23, and the end of the screw 11 is threadedly connected to the inner wall of the screw 11, and the two ropes 13 are used to assist the connecting plate 7 and the plug block 5 to connect the corrective shoe 10 under the leg guard 1 and make the opening of the corrective shoe 10 consistent with the opening of the leg guard 1, so that when massaging the child's foot, there is no need to disassemble the corrective shoe 10 and the leg guard 1 together, which simplifies the wearing steps and facilitates the caregivers or family members to wear and remove the foot deformity correction brace.

[0027] Furthermore, the sliding hole 28 is symmetrically provided with sliding grooves 29 on the upper and lower sides near the leg guard 1, and the upper and lower sides of the sliding plate 4 are symmetrically installed with arc-shaped limit plates 3, and the limit plates 3 are slidably embedded in the sliding grooves 29. An arc-shaped fixing plate 2 is arranged above the leg frame 6, and the arc-shaped fixing plate 2 is slidably set on the leg guard 1, and a plurality of positioning rods 14 are symmetrically fixedly installed at equal intervals on the bottom of the arc-shaped fixing plate 2, and second sockets 26 are equidistantly provided on the top of the leg frame 6, and third sockets 30 are equidistantly provided on the top of the limit plate 3 near the arc-shaped fixing plate 2, and the opening interval of the second sockets 26 is the same as the opening interval of the third sockets 30, and the positioning rod 14 passes through the second socket 26 and penetrates the leg frame 6 and is embedded in the third socket 30.

[0028] Please refer to Figure 1-Figure 6 , the leg frame 6 and the shoe frame 8 are installed to transform the foot and the back of the leg into arcs of the same size, and the corrective shoe 10 and the leg guard 1 are connected through the connecting plate 7 and the screw 11, and then the corrective shoe 10 is rotated to drive the sliding plate 4 to slide inside the sliding hole 28 through the connecting plate 7, and the deflection angle of the corrective shoe 10 is adjusted with the calf as the center of the circle. After the adjustment is completed, the arc fixing plate 2 is moved from top to bottom so that the positioning rod 14 is embedded in the third plug hole 30 through the second plug hole 26 to complete the leg guard 1 and the corrective shoe 1. 0 is fixedly connected, so that the corrective shoe can be used alone without the need to cooperate with the corrective plate for angle adjustment, and thus the child's mobility will not be deprived when wearing it, and the child's resistance to the corrective shoe is reduced. In addition, since the positions of the positioning rod 14, the second plug hole 26 and the third plug hole 30 are relatively fixed, the corrective shoe 10 can only be fixed at a preset angle, which is convenient for family members to independently and accurately adjust the deflection angle of the corrective shoe 10 as the child wears it for a longer time, and the accuracy of the corrective shoe 10 when adjusting the deflection angle is improved, thereby improving the correction effect.

[0029] In addition, since the limiting plate 3 is slidably engaged in the sliding groove 29 , the sliding plate 4 can only slide in the sliding hole 28 , thereby preventing the sliding plate 4 from being separated from the sliding hole 28 .

[0030] Furthermore, first sockets 22 are evenly spaced at the bottom of the shoe frame 8. The spacing between the first sockets 22 and the second sockets 26 is the same, and rubber rings 20 are fixedly installed on the inner walls of the first sockets 22 and the second sockets 26. The inner walls of the rubber rings 20 are in contact with the positioning rod 14.

[0031] Please refer to Figure 1-Figure 2 and Figure 7 In the early stage of wearing, the arc fixing plate 2 can be removed from the leg frame 6 at a fixed time, and inserted into the inside of the shoe frame 8 from bottom to top, so that the positioning rod 14 is embedded in the first plug hole 22 after squeezing the rubber ring 20, and the arc fixing plate 2 is fixed to the bottom of the shoe frame 8 by the friction force of the rubber ring 20. At this time, the fixed connection between the leg guard 1 and the corrective shoe 10 is disconnected, so that the corrective shoe 10 is in an active state. Under the influence of the deformed foot, the corrective shoe 10 begins to rotate under the leg guard 1. The rotation of the corrective shoe 10 drives the sliding plate 4 to slide in the sliding hole 28 through the connecting plate 7, thereby stretching or squeezing the first springs 12 on both sides, and at the same time, the displacement of the screw 11 The rotating rod 18 on one side is also pulled synchronously, so that the rotating rod 18 compresses the second spring 19 while driving the circular plate 17 to rotate. The elasticity of the first spring 12 and the second spring 19 is utilized to ensure that the corrective shoe 10 rotates under the influence of the deformed foot, thereby reducing the huge pressure exerted by the deformed foot on the child's foot when wearing it, and reducing the squeezing force of the deformed foot on the child's foot. Under the action of elasticity, the inner wall of the corrective shoe 10 is driven to always be close to the child's foot and exert a smaller corrective force on the foot. While ensuring that the corrective shoe 10 has a certain corrective effect, the squeezing force on the child's foot is minimized to help the child quickly adapt to the feeling of wearing the corrective shoe in the early stage of wearing.

[0032] Furthermore, a rubber layer 25 is fixedly provided on the inner wall of the leggings 1, and ventilation grooves 24 are evenly spaced apart on the side of the rubber layer 25 away from the leggings 1, and a ventilation layer 27 is adhered to the side of the rubber layer 25 away from the leggings 1, and the ventilation layer 27 is in contact with the skin.

[0033] Please refer to Figure 3 The installed rubber layer 25 allows the leggings 1 to fit tightly against the child's calf, and the Velcro on the existing leggings 1 is used to fix the leggings 1 to ensure that the leggings 1 will not deviate on the calf. The provision of the ventilation grooves 24 increases the breathability of the leggings 1, preventing the calf from being in contact with the rubber layer 25 for a long time, thereby preventing bacteria from breeding and causing itching of the child's calf.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
