Description

Technical Field

[0001] This application relates to the field of foot arch measurement technology, and in particular to a foot arch data measuring device and method. Background Technology

[0002] In situations requiring customized or corrective insoles, obtaining accurate arch data is a crucial foundation. Currently, in most podiatric clinics, rehabilitation centers, or shoe stores, due to the high cost and environmental requirements of optical 3D scanners, the traditional method commonly used is manual measurement. Staff members use simple tools such as calipers, measuring boards, and rulers, relying on their personal experience to manually measure and interpret the customer's arch. During measurement, customers are usually asked to alternately lift one foot, and then staff members use tools to measure. This is not only inefficient but also disrupts the symmetry and balance of the feet when standing naturally, failing to reflect the arch shape under actual stress. Furthermore, traditional measuring tools are mostly vertical measuring boards or rulers, which are difficult to adapt to the complex curves of the arch and cannot accurately measure the true height of key arch bones, thus making it difficult to guarantee measurement accuracy. Summary of the Invention

[0003] In order to improve the accuracy of foot arch measurement and thus enable the selection or customization of highly adaptable orthotic insoles for the measured person, this application provides a foot arch data measurement device and measurement method.

[0004] On the one hand, the foot arch data measuring device provided in this application adopts the following technical solution: A foot arch measurement device includes a base, on which a first placement plate, a second placement plate, and a seat are disposed. The first and second placement plates are respectively used to place the feet of the subject. The top sides of the first and second placement plates are flush with each other. A movable foot arch measuring block is disposed on the top of the base. The foot arch measuring block is used to abut against the arch of the subject's foot. The range of motion of the foot arch measuring block includes the area above the first placement plate, above the second placement plate, and above the gap between the first and second placement plates. The bottom side of the foot arch measuring block is flush with the top side of the first placement plate. The foot arch measuring block is provided with measurement markings.

[0005] By adopting the above technical solution, when it is necessary to measure the arch data of the subject, the subject can be seated with both feet placed on the first and second placement plates. At this time, the pressure on the feet is small, and it is easy to straighten the posture of the legs and feet. The arch measuring block can be moved closer to the arch of the subject in the seated position and placed against the arch for measurement. The reading is taken from the position where the arch measuring block is in contact with the arch, thereby improving the accuracy of the measurement. Alternatively, the subject can be standing to measure in the standing position, thereby obtaining data on the arch under different actual force conditions, further improving the accuracy of the measurement.

[0006] Optionally, the arch measuring block includes a marking side and a measuring side. The measuring markings of the arch measuring block are set along the height direction on the marking side. The measuring side of the arch measuring block is in the shape of continuous steps. The steps on the measuring side of the arch measuring block correspond to the measuring markings on the marking side of the arch measuring block. The end of the measuring side of the arch measuring block away from the marking surface is a measuring tip. The line connecting the endpoints of the steps of the measuring tip is curved.

[0007] By adopting the above technical solution, during measurement, the measuring tip can easily approach the stress point of the arch of the foot and abut against the lower side of the arch. The arch data can then be obtained through the corresponding measuring marks, thereby improving the accuracy of arch measurement.

[0008] Optionally, the base is provided with a first leg fixing assembly and a second leg fixing assembly, the first placement plate is provided with a first heel plate, and the second placement plate is provided with a second heel plate.

[0009] By adopting the above technical solution, the first heel plate and the second heel plate can be used to determine the position of the heel, and the first leg fixing component and the second leg fixing component can be used to temporarily correct the leg shape, which facilitates accurate measurement.

[0010] Optionally, the first placement plate is slidably connected to the base, the second placement plate is slidably connected to the base, the base is provided with a sliding drive for driving the first placement plate and the second placement plate to move closer or further apart, the first fixed leg assembly is connected to the first placement plate, and the second fixed leg assembly is connected to the second placement plate.

[0011] By adopting the above technical solution, after the person being measured places their feet, the sliding drive can be used to move the first placement plate and the second placement plate closer or further apart, adjusting the distance between the feet to ensure that the feet are in a healthy posture for measurement.

[0012] Optionally, the first leg-fixing assembly includes a first push-out drive and a first clamping drive. The first push-out drive is connected to a first placement plate. A first slide block is slidably connected to the first placement plate. The first slide block is connected to the drive end of the first push-out drive. The first clamping drive is mounted on the first slide block. A first clamp is slidably connected to the first slide block. The first clamp is connected to the drive end of the first clamping drive. The second leg-fixing assembly includes a second push-out drive and a second clamping drive. The second push-out drive is connected to a second placement plate. A second slide block is slidably connected to the second placement plate. The second slide block is connected to the drive end of the second push-out drive. The second clamping drive is mounted on the second slide block. A second clamp is slidably connected to the second slide block. The second clamp is connected to the drive end of the second clamping drive.

[0013] By adopting the above technical solution, the first clamp and the second clamp can hold the lower leg of the person being measured, so that the leg and foot are in a straight position. Optionally, the side wall of the seat portion is provided with a receiving groove for accommodating the first fixed leg assembly and the second fixed leg assembly.

[0014] By adopting the above technical solution, when no measurement is required or after the measurement is completed, the first push-out drive and the second push-out drive can drive the first slide, the second slide, the first clamping drive and the second clamping drive to move into the receiving groove for storage.

[0015] Optionally, the base is provided with a movable seat and a moving drive for driving the movable seat to move, and the arch measuring block is movably connected to the movable seat.

[0016] By adopting the above technical solution, after the subject places both feet, the moving drive can be made to move the moving seat, which in turn moves the arch measuring block, thereby measuring the corresponding position of the subject's arch.

[0017] Optionally, the movable seat is provided with a telescopic rod, the arch measuring block is installed at the end of the telescopic rod, and the base is provided with a marking plate with length markings. The arrangement direction of the length markings is perpendicular to the sliding direction of the first placement plate.

[0018] By adopting the above technical solution, the arch measuring block can be moved to the corresponding measuring position through the extension and retraction of the telescopic rod and the movement of the movable seat. According to the length marking on the label, the distance data between the arch measuring position and the heel is collected, which makes it easier to further determine the position where the arch needs support and improves the measurement accuracy.

[0019] Optionally, the end of the telescopic rod is provided with a rotating block, the arch measuring block is detachably connected to the rotating block, each step on the measuring side of the arch measuring block is provided with a light strip, each step on the measuring edge is provided with a sensor, and the sensor is electrically connected to the light strip.

[0020] By adopting the above technical solution, when the measuring tip of the arch measuring block touches the arch of the foot, the pressure causes the light strip to light up, thereby identifying the corresponding measurement mark and improving the accuracy of the measurement.

[0021] On the other hand, the foot arch data measuring device provided in this application adopts the following technical solution: A method for measuring foot arch data, comprising: s1: Have the subject sit in the seat area and place both feet on the first and second placement boards respectively; s2: Adjust the direction of the subject's knees and the distance between their feet, and straighten the subject's legs; s3: Move the arch measuring block so that it comes close to the arch of the subject and measures the position of the bones in the arch. s4: Have the subject stand up, straighten the subject's legs, move the arch measuring block so that it comes close to the subject's arch again, and measure the position of the bones in the arch.

[0022] By adopting the above technical solution, the posture of the subject's legs and feet is corrected so that the subject's feet are in a temporarily corrected position. Then, measurements are taken in sitting and standing positions to obtain more accurate data. This allows for analysis of the subject's arch shape in a normal posture, which facilitates the selection or customization of highly adaptable orthotic insoles.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. When measuring the arch data of a subject, the subject can sit in the seat and place both feet on the first and second placement plates. At this time, the pressure on the feet is small, and it is easy to straighten the posture of the legs and feet. The arch measuring block can be moved closer to the arch of the subject in the seated position and placed against the arch for measurement. The reading is taken through the position where the arch measuring block is in contact with the arch, thereby improving the accuracy of the measurement. Alternatively, the subject can stand to measure in the standing position, thereby obtaining the data of the arch under different actual force conditions, further improving the accuracy of the measurement. 2. During measurement, the measuring tip is easily close to the stress point of the arch of the foot, and is placed against the lower side of the arch. The arch data is obtained through the corresponding measuring marks, thereby improving the accuracy of the arch measurement. 3. By correcting the posture of the subject's legs and feet, the subject's feet are placed in a temporarily corrected position. Measurements are then taken in sitting and standing positions to obtain more accurate data.

[0031] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0032] This application discloses a foot arch data measuring device and method.

[0033] Reference Figure 1 and Figure 2A foot arch measurement device includes a base 1, on which a first placement plate 2, a second placement plate 3, and a seat 11 are disposed. The first placement plate 2 and the second placement plate 3 are horizontally disposed on the top of the base 1 and are symmetrical to each other. The first placement plate 2 and the second placement plate 3 are respectively used to place the feet of the subject. The top side of the first placement plate 2 is flush with the top side of the second placement plate 3. A movable foot arch measuring block 4 is disposed on the top of the base 1. The foot arch measuring block 4 is used to abut against the arch of the person. The range of motion of the foot arch measuring block 4 includes the area above the first placement plate 2, the area above the second placement plate 3, and the area above the gap between the first placement plate 2 and the second placement plate 3. The bottom side of the foot arch measuring block 4 is flush with the top side of the first placement plate 2. The foot arch measuring block 4 is provided with a measurement mark 411. The seat 11 is rectangular box-shaped, and a cushion 111 is provided on the top of the seat 11.

[0034] When measuring the arch data of a subject, the subject can sit on the seat 11 with their feet placed on the first placement plate 2 and the second placement plate 3 respectively. After aligning the lower legs and knees, the staff can move the arch measuring block 4 to the arch positions of the subject's feet, bringing it close to the corresponding positions of the first metatarsal bone, medial cuneiform bone, navicular bone, and talus bone in the subject's arch. This allows for the collection of height data at various points on the arch position under conditions of low pressure on the feet, such as when the subject is seated. After measurement, the subject can stand in place, keeping both feet... Without shifting, align the lower leg and knee, then move the arch measuring block 4 closer to the corresponding positions of the bones in the arch of the subject's foot. Measure the height data of each position of the arch in a standing state. This allows for comparison and analysis of the two sets of data, facilitating the selection or customization of appropriate orthotic insoles. Since both feet are placed on the first placement plate 2 and the second placement plate 3 respectively during measurement, both feet are in the measurement state, rather than alternating between the two feet. Furthermore, arch data can be obtained in both sitting and standing positions, thus improving measurement accuracy. This allows for better selection or customization of highly suitable orthotic insoles for the subject.

[0035] Reference Figure 2 and Figure 3The outer side of the arch measuring block 4 includes a marking side 41 and a measuring side 42. The marking side 41 is a vertical plane. The measuring mark 411 of the arch measuring block 4 is set vertically on the marking side 41. The measuring side 42 of the arch measuring block 4 is a continuous step shape that gradually narrows from the bottom to the top. The steps of the measuring side 42 of the arch measuring block 4 correspond to the measuring mark 411 of the marking side 41 of the arch measuring block 4. The end of the measuring side 42 of the arch measuring block 4 away from the marking surface is the measuring tip 43. The measuring tip 43 is used to contact the arch of the subject. The platform wall of each step of the measuring tip 43 is a curved slope. The line connecting the endpoints of the steps of the measuring tip 43 is curved. In this embodiment, the line connecting the endpoints of the steps of the measuring tip 43 is a logarithmic curve. The two sides of the cross section of the measuring side 42 are symmetrical curves with the measuring tip 43 as the symmetrical point. The length of the cross section curve of the measuring side 42 decreases from the bottom to the top.

[0036] During measurement, the movable arch measuring block 4 is moved so that the measuring tip 43 of the arch measuring block 4 is moved toward the arch of the subject. The bottom end of the measuring tip 43 is inserted into the gap between the arch and the first placement plate 2 or the second placement plate 3 until one of the steps of the measuring tip 43 abuts against the measured position of the arch. The height data of the measured position of the arch can be obtained through the corresponding measuring mark 411 of the step. This method replaces the traditional vertical measuring board or vertical measuring ruler. Since the line connecting the endpoints of the steps of the measuring tip 43 is curved, the step of the measuring tip 43 can abut against the lower or even directly below the arch during measurement. This makes it easier to approach the stress point of the arch than traditional measuring boards and measuring rulers, resulting in a more accurate measurement position. The accurate arch data can be obtained through the corresponding measuring mark 411 of the step, thereby improving the accuracy of arch measurement and facilitating the selection or customization of highly adaptable orthotic insoles.

[0037] Reference Figure 1 and Figure 4 The base 1 is provided with a first leg fixing component and a second leg fixing component, which are used to straighten or fix the lower leg of the person being measured. The first placement plate 2 is provided with a first heel plate 21, which is in the shape of a curved plate and is close to the seat part 11. The second placement plate 3 is provided with a second heel plate 31, which is in the shape of a curved plate and is close to the seat part 11. The shape of the first heel plate 21 is consistent with the shape of the second heel plate 31, and the first heel plate 21 and the second heel plate 31 are symmetrical.

[0038] When the subject places both feet on the first placement plate 2 and the second placement plate 3, the heels can be placed against the inner arc sidewall of the first heel plate 21 and the inner arc sidewall of the second heel plate 31 respectively to determine the position of the heels. Then, the first leg fixing component and the second leg fixing component are used to straighten the legs, thereby temporarily correcting the leg shape of heel eversion or inversion. This allows the subject to be measured in a relatively healthy state after the feet are temporarily corrected, which makes it easier to measure accurate arch data.

[0039] Reference Figure 1 and Figure 4 The first placement plate 2 is slidably connected to the base 1, and the first placement plate 2 slides horizontally. The second placement plate 3 is also slidably connected to the base 1, and the second placement plate 3 slides horizontally. The sliding paths of the first placement plate 2 and the second placement plate 3 are collinear, and the sliding directions of the first placement plate 2 and the second placement plate 3 are opposite. The bottom of the first placement plate 2 is provided with a first sliding block 22, and the bottom of the second placement plate 3 is provided with a second sliding block 32. The top side of the base 1 is provided with a sliding groove 12 for the first sliding block 22 and the second sliding block 32 to slide. The sliding groove 12 is provided with a mechanism for driving the first sliding block 22 and the second sliding block 32. A sliding drive 13, which is a motor, is used to move closer to or further away from a first placement plate 2 and a second placement plate 3. A bidirectional screw 14 is rotatably connected to the wall of a sliding groove 12. The bidirectional screw 14 is connected to the drive end of the sliding drive 13. A first sliding block 22 and a second sliding block 32 are threadedly connected to the bidirectional screw 14. The first sliding block 22 and the second sliding block 32 are symmetrically arranged. When the bidirectional screw 14 rotates, the first sliding block 22 and the second sliding block 32 move closer to or further away from each other. A first fixed leg assembly is connected to the first placement plate 2, and a second fixed leg assembly is connected to the second placement plate 3.

[0040] When the subject places their heels against the side wall of the first heel plate 21 and the inner arc side of the second heel plate 31, the sliding drive 13 drives the bidirectional screw 14 to rotate. The first sliding block 22 and the second sliding block 32 move the first placement plate 2 and the second placement plate 3 closer or further apart, thereby adjusting the distance between the feet according to the subject's shoulder width. During adjustment, the first leg-fixing component moves with the first placement plate 2 and the second leg-fixing component moves with the second placement plate 3. After adjustment, the first leg-fixing component and the second leg-fixing component can be used to straighten the subject's lower legs, thereby ensuring that the feet are in a healthy posture for measurement.

[0041] Reference Figure 1 and Figure 5The first fixed leg assembly includes a first push-out drive 23 and a first clamping drive 24. The first push-out drive 23 is connected to the first placement plate 2 and is a cylinder. A first slide block 25 is slidably connected to the first placement plate 2. The sliding direction of the first slide block 25 is perpendicular to the sliding direction of the first placement plate 2. The first slide block 25 is connected to the drive end of the first push-out drive 23. The first clamping drive 24 is mounted on the first slide block 25. A first clamp 26 is slidably connected to the first slide block 25 and is connected to the drive end of the first clamping drive 24. The first clamping drive 24 is a pneumatic gripper. There are two first clamps 26, which are symmetrically arranged. The first clamping drive 24 can drive the two first clamps 26 to move closer or further apart. The first clamp 26 is an arc-shaped clamp.

[0042] The second fixed leg assembly includes a second push-out drive 33 and a second clamping drive 34. The second push-out drive 33 is connected to the second placement plate 3 and is a cylinder. A second slide block 35 is slidably connected to the second placement plate 3. The sliding direction of the second slide block 35 is perpendicular to the sliding direction of the second placement plate 3. The second slide block 35 is connected to the drive end of the second push-out drive 33. The second clamping drive 34 is mounted on the second slide block 35. A second clamp 36 is slidably connected to the second slide block 35 and is connected to the drive end of the second clamping drive 34. The second clamping drive 34 is a pneumatic gripper. There are two second clamps 36, which are symmetrically arranged. The second clamping drive 34 can drive the two second clamps 36 to move closer or further apart. The second clamp 36 is an arc-shaped clamp.

[0043] After the subject places both feet on the first placement plate 2 and the second placement plate 3, the first push-out drive 23 and the second push-out drive 33 can respectively drive the first slide block 25 and the second slide block 35 to slide closer to the subject's legs, so that the subject's legs are located between the two first clamps 26 or the two second clamps 36. The first clamping drive 24 drives the first clamps 26 to move closer to each other, and the second clamping drive 34 drives the second clamps 36 to move closer to each other, thereby clamping the subject's lower legs. With the help of the first heel plate 21 and the second heel plate 31, the legs and feet are in a straight position, reducing heel outward or inward turning and improving measurement accuracy.

[0044] The side wall of the seat part 11 is provided with a receiving groove 112. The receiving groove 112 faces the first placement plate 2 and the second placement plate 3. The first placement plate 2 and the second placement plate 3 both extend into the receiving groove 112. The receiving groove 112 is used to store the first fixed leg assembly and the second fixed leg assembly. The first push-out drive member 23 and the second push-out drive member 33 are both located in the receiving groove 112. When no measurement is required or after the measurement is completed, the first push-out drive member 23 and the second push-out drive member 33 drive the first slide 25, the second slide 35, the first clamping drive member 24 and the second clamping drive member 34 to move into the receiving groove 112 for storage.

[0045] The top of the base 1 is provided with a movable seat 5 and a movable drive component 15 for driving the movable seat 5 to move. The movable seat 5 is slidably connected to the top of the base 1. The sliding direction of the movable seat 5 is consistent with the sliding direction of the first placement plate 2. The arch measuring block 4 is movably connected to the movable seat 5. The movable drive component 15 is a motor. The drive end of the movable drive component 15 is connected to an adjusting screw 16. The end of the adjusting screw 16 is rotatably connected to the base 1. The adjusting screw 16 is threadedly connected to the movable seat 5.

[0046] Before the subject places both feet, the arch measuring block 4 is moved between the foot placement areas. After the subject places both feet, the arch measuring block 4 is positioned between the subject's feet. The moving drive 15 drives the adjusting screw 16 to rotate, causing the moving seat 5 and the arch measuring block 4 to slide. Then, the arch measuring block 4 moves relative to the moving seat 5, so that the measuring tip 43 of the arch measuring block 4 comes close to the subject's arch to be measured, thereby measuring the height data of the corresponding position of the arch.

[0047] Reference Figure 1 and Figure 6 A telescopic rod 51 is provided on the movable seat 5. The telescopic rod 51 extends horizontally. The telescopic rod 51's telescopic direction and extension direction are perpendicular to the sliding direction of the movable seat 5. The arch measuring block 4 is installed at the end of the telescopic rod 51 away from the movable seat 5. A marking plate 17 is embedded in the top surface of the base 1. The marking plate 17 is located below the first placement plate 2. The marking plate 17 has length markings. The arrangement direction of the length markings is perpendicular to the sliding direction of the first placement plate 2. The starting point extension line of the length markings is tangent to the inner arc side of the first heel plate 21.

[0048] Since the heels of the subject's feet are pressed against the inner arc sides of the first heel plate 21 and the second heel plate 31 during measurement, when the arch measuring block 4 is used to measure the arch, the arch measuring block 4 reaches the corresponding measurement position by extending and retracting the telescopic rod 51 and driving the sliding seat 5. According to the length mark corresponding to the arch measuring block 4 after the telescopic rod 51 extends and retracts, the distance data between the arch measuring position and the heel can be collected, which is convenient for analyzing the specific position where the arch needs support, and thus facilitates the selection or customization of orthopedic insoles that fit the subject's feet.

[0049] A rotating block 52 is installed and connected to the end of the telescopic rod 51 away from the movable base 5. The rotation axis of the rotating block 52 extends vertically. The arch measuring block 4 is detachably connected to the rotating block 52. A fixing plate 44 is provided on the marking side 41 of the arch measuring block 4. The fixing plate 44 is installed on the rotating block 52 by bolts and nuts. Each step of the measuring side 42 of the arch measuring block 4 is equipped with a light strip. The arch measuring block 4 is made of light-transmitting plastic material. Each step of the measuring tip 43 is equipped with a pressure sensor. The pressure sensor is electrically connected to the light strip.

[0050] During measurement, the measuring tip 43 of the arch measuring block 4 is placed against the corresponding position on the arch of the foot. The pressure sensor on the corresponding step of the measuring tip 43 receives pressure through the contact, thereby causing the light strip of the corresponding step to light up. This allows the measurer to identify the corresponding measurement mark 411 by the light, improving the accuracy of the measurement. Since the rotating block 52 and the telescopic rod 51 are rotatably connected, the angle of the arch measuring block 4 can be adjusted by rotating the block 52, thereby adjusting the angle of the arch measurement and improving the accuracy of the measurement. The data of both feet are measured sequentially by rotating the block 52 and moving the movable seat 5.

[0051] A control panel 18 is provided on one side of the base 1. The control panel 18 is electrically connected to the moving drive component 15. A camera 53 is connected to the side wall of the rotating block 52 via a bracket. The camera 53 faces the measuring point 43 of the arch measuring block 4. A display screen 19 is provided on the control panel 18. The display screen 19 is electrically connected to the camera 53.

[0052] During measurement, the camera 53 and the display screen 19 are used to observe the measurement position, which helps to accurately read the measurement mark 411 and improve the measurement accuracy.

[0053] A method for measuring foot arch data includes the following steps: s1: Have the subject sit in the seat 11, and place the subject's feet on the first placement plate 2 and the second placement plate 3 respectively, with the heels resting against the inner arc side of the first heel plate 21 and the inner arc side of the second heel plate 31 respectively. s2: Adjust the knee direction and the distance between the feet of the person being measured. The knee direction of the person being measured can be straightened by the staff. The bidirectional screw 14 can be rotated by the sliding drive 13 to make the first placement plate 2 and the second placement plate 3 move closer or further apart, thereby adjusting the distance between the feet. The first push-out drive 23 and the second push-out drive 33 respectively push out the first clamping drive 24 and the second clamping drive 34. The first clamping drive 24 drives the first clamp 26 to move closer together, and the second clamping drive 34 drives the second clamp 36 to move closer together, thereby straightening the lower leg of the person being measured and aligning the legs of the person being measured. s3: Move the foot arch measuring block 4 and bring it close to the corresponding measurement positions of the bones of the foot arch of the person being measured, such as the first metatarsal, medial cuneiform, navicular bone and talus, to measure the corresponding foot arch height data of the person being measured in a normal sitting position. s4: Have the subject stand up, straighten the subject's legs, clamp the subject's lower legs again, move the arch measuring block 4, bring the arch measuring block 4 close to the measuring positions of the subject's arch bones, and measure the corresponding arch height data of the subject in a normal standing posture.

[0054] By correcting the posture of the subject's legs and feet, the bones of the subject's legs and feet are brought back to a healthy position as much as possible. This puts the subject's feet in a relatively healthy state after temporary correction. In this state, the arches of the feet are measured in both sitting and standing positions to determine the height and state of the arches under different pressure conditions. This makes it easier to customize or select orthotic insoles from pre-made insoles to fit the subject's feet.

[0055] The above are all preferred embodiments of this application. These embodiments are only explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
