Abstract
Description
Technical Field
[0001] This utility model relates to the field of foot data measurement technology, and in particular to a foot measuring instrument. Background Technology
[0002] A person's left and right feet rarely have exactly the same length and width. Therefore, it is necessary to measure the soles of both feet before purchasing shoes of the appropriate size. In particular, the medial metatarsophalangeal muscle generally bulges on the side behind the big toe compared to the muscles at the front and back, while the lateral metatarsophalangeal muscle curves outward on the side behind the little toe. Therefore, accurate measurement of foot width requires certain auxiliary methods.
[0003] Currently, shoe sizes are determined by foot length, specifically the distance from the longest toe to the heel. However, this ignores the fact that foot width varies from person to person. As a result, the shoes purchased often do not match the foot measurements, leading to the following issues: Too long or too wide: Unstable and unsafe to walk in, and there is a risk of shoes falling off during wearing; Too short or too narrow: It compresses the feet, and long-term use can lead to foot deformities, such as flat feet, hallux valgus, and collapsed arches.
[0004] When trying on shoes in person, you can adjust the size based on whether the shoes feel tight. However, with online shopping being the norm, returning or exchanging shoes that are the correct size but don't fit properly is extremely troublesome.
[0005] Based on this, the industry has tried to solve the corresponding problems. For example, there are foot measuring devices sold on Taobao. These devices are shaped like insoles and have shoe length indicators and heel sections. They can measure personal foot length information, but these products cannot measure accurate foot width information, and the products have defects.
[0006] Furthermore, in addition to the above products, a foot width measuring area is added. In order to accurately measure the width between the inner and outer metatarsal muscles of the left and right feet while measuring the foot length, two foot measuring instruments must be purchased for the left and right feet, which results in waste.
[0007] Another product sold on Taobao is the American-made BRANNOCK foot measuring device. Shaped like a boat, it has a heel section at the bow for the left foot and a heel section at the stern for the right foot. It features a vertical foot width adjustment groove on one side and a horizontal adjustment groove on the other for accurately measuring foot width. However, this product is too long, leading to material consumption and making it inconvenient to store.
[0008] In summary, the existing technology has the following drawbacks: 1) Limited Measurement Function: Traditional foot measuring tools, such as "foot measuring devices," only measure foot length using shoe length indicators and the heel, completely ignoring foot width data. However, foot width varies significantly among different groups; for example, the width of a normal foot can differ from that of a flat foot by 1-2 cm. Choosing shoes solely based on foot length can easily lead to the problem of "shoes that fit the right length but cause pressure on the instep." In online shopping scenarios, frequent returns and exchanges due to mismatched foot widths result in a poor user experience and wasted logistics resources.
[0009] 2) Insufficient left and right foot compatibility: Some improved foot measuring instruments, such as those with added foot width measuring areas, require separate purchase for the left and right feet. The reasons are as follows: The medial and lateral metatarsal muscles of the left and right feet are symmetrically positioned, and the fixed stop structure of existing tools cannot accommodate both feet simultaneously. For example, a certain foot measuring device is designed with an inner curved stop for the left foot, but when used with the right foot, the mismatch in structure may lead to a measurement error of ±0.5cm.
[0010] Consumers are wasting money by purchasing separate foot measuring devices for their left and right feet.
[0011] 3) Structural design flaws: The American BRANNOCK foot measuring instrument adopts a "bow-stern" double heel design, with a length of 50cm, which is more than 20cm longer than conventional products, increasing the cost of consumables by 40% and making it inconvenient to carry.
[0012] In view of the shortcomings of the existing technology, this utility model proposes a plantar measuring instrument that can simultaneously and accurately measure the foot length and foot width data of the left and right feet. Utility Model Content
[0013] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a foot measuring device to safeguard foot health.
[0014] The above-mentioned objective of this utility model is achieved through the following technical means: A foot measuring device includes a base plate 1, which includes a forefoot portion 11, a heel portion 12 and a heel portion 13 from top to bottom; it also includes a panel 2 mounted on the forefoot portion 11 and capable of rotating relative to the forefoot portion 11. The panel 2 is provided with a foot length measuring area 3 and a foot width measuring area 4; The foot length measuring area 3 has a foot length indicator groove 31 and a foot length indicator 32 that can slide on the foot length indicator groove 31.

[0015] Preferably, the forefoot portion 11 has a central hole 111, and the panel 2 is provided with a fastener 21 that cooperates with the central hole 111.
[0016] Optionally, the fastener 21 is an elastic element, the central hole 111 has an inner lip 112, the fastener 21 is a round, protruding, tapered button, and the button has a pressure cap 211, the outer diameter of which is larger than the inner diameter of the central hole 111.
[0017] Optionally, the fastener 21 is composed of a circular hole 212 and a plurality of arc-shaped insert pieces 213 arranged circumferentially on the inner wall of the circular hole 212. The arc-shaped insert pieces 213 are elastic elements with an outer lip edge 214. The central hole 111 has an inner lip edge 112. The inner diameter of the circular hole 212 is equivalent to the inner diameter of the central hole 111.
[0018] Preferably, the forefoot portion 11 and the panel 2 are both disc-shaped.
[0019] Furthermore, the forefoot portion 11 is generally shaped as a large disc with two ear portions 113 facing each other on both sides; The overall shape of the panel 2 is a small disc with a single ear 22 on one side.
[0020] Preferably, the forefoot portion 11 is provided with a limiting member for restricting further rotation of the single ear portion 22.
[0021] Optionally, the foot length indicator 32 includes at least one of the following: a cross-shaped indicator or a chain-head-shaped indicator.
[0022] Preferably, the foot width indicator 43 is arranged perpendicular to the lateral muscle guard strip 42.
[0023] Preferably, the medial muscle block 45 has an inner arc bend 451 that cooperates with the medial phalangeal muscle on the side closest to the lateral muscle block 42.
[0024] The beneficial effects of adopting the above technical solution are as follows: This foot measuring device can simultaneously measure foot length and width, safeguarding foot health and overcoming the limitation of existing tools that only measure foot length. The panel is rotatable, allowing the same foot measuring device to be adapted to measure the length and width of both feet, making it more material-efficient and portable compared to existing foot measuring devices. The medial muscle stop conforms to the contour of the phalangeal muscles, improving the accuracy of foot width measurement. The foot length indicator, foot width indicator, and medial muscle stop are all adjustable by sliding, making it suitable for a wider range of users. Attached Figure Description

Detailed Implementation
[0027] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example 1. Figure 1-10 A foot measuring device is shown, including a base plate 1, which includes a forefoot portion 11, a heel portion 12 and a heel portion 13 from top to bottom; it also includes a panel 2 mounted on the forefoot portion 11 and capable of rotating relative to the forefoot portion 11. The panel 2 is provided with a foot length measuring area 3 and a foot width measuring area 4; The foot length measuring area 3 has a foot length indicator groove 31 and a foot length indicator 32 that can slide on the foot length indicator groove 31. The foot length indicator groove 31 is provided with a length mark. The foot width measurement area 4 includes: a foot width transverse groove 41 located on one side of the foot length measurement area 3, a width mark located on the side of the foot width transverse groove 41, a foot width indicator 43 with a lateral muscle stop 42 that can slide on the foot width transverse groove 41, a foot width vertical groove 44 located on the other side of the foot length measurement area 3, and a medial muscle stop 45 that can slide on the foot width vertical groove 44.
[0030] Working principle: Place the foot on the base plate with the heel close to the heel part 13. Rotate the panel 2 to align the foot length measuring area 3 with the heel part 12 and the heel part 13. Slide the foot length indicator 32 to make the longest toe touch the foot length indicator 32 to measure the foot length. Slide the medial muscle stop 45 so that its inner arc bend 451 fits against the medial metatarsal muscle on the inside of the foot to locate the measurement reference. Slide the foot width indicator 43 so that the lateral muscle stop 42 fits against the lateral metatarsal muscle on the outside of the foot. At this time, the scale value of the foot width indicator 43 corresponding to the width scale is the measured foot width.
[0031] Application example: A 9-year-old boy's foot data was measured, such as... Figure 7 The measurements shown indicate that the left foot is 20.6 cm long and 7.5 cm wide. Figure 8After rotating panel 2, the length of the right foot was measured to be 20.5cm and the width of the right foot to be 7.4cm.
[0032] Shoe purchasing guide: When buying shoes, the left and right shoes are usually the same size. Therefore, if there is a difference in the measurements of the left and right feet, take the larger of the length and width as the standard. That is, use a foot length of 20.6cm and a foot width of 7.5cm as the standard for selecting shoes.
[0033] If the seller does not provide a standard for foot width selection, choosing a size 35-36 shoe is more suitable. Choosing a size 35 shoe will make the right foot feel comfortable but the left foot will feel pressured, which may affect the health of the left foot and may lead to foot deformities such as bunions in the long run. Choosing a size 36 shoe will make the left foot feel comfortable but the right foot will feel loose, which may affect the stability of the fit and may cause the shoe to slip off.
[0034] If the seller provides size 36 shoes, which correspond to a foot length of 20.5±0.1cm and a foot width of 7.5±0.1cm, then size 36 is the first choice. Both feet will have a comfortable experience, and long-term wear will not affect the health of the feet.
[0035] Customization Reference: Send the length and width data of your left and right feet to the merchant to customize exclusive shoes, ensuring the comfort, stability, and foot health of both shoes.
[0036] It should be noted that the dimensions or numbers in the attached diagrams are merely examples. There are significant differences between foot data for children and adults, so this foot measuring device should be adapted to the appropriate size.
[0037] This embodiment can simultaneously measure foot length and foot width, safeguarding foot health and overcoming the limitation of existing tools that only measure foot length; the panel is rotatable, and the same plantar measuring instrument can be adapted to measure the length and width of both feet, making it more material-efficient and portable than existing foot measuring instruments; the medial muscle stop conforms to the contour of the phalangeal muscles, improving the accuracy of foot width measurement; the foot length indicator, foot width indicator, and medial muscle stop are all adjustable by sliding, making it suitable for a wider range of users.
[0038] Example 2. This example illustrates the connection structure between the central hole and the round fastener, as follows: Figure 4-5 As shown in Figures 13-14, the forefoot portion 11 has a central hole 111, and the panel 2 is provided with a fastener 21 that cooperates with the central hole 111.
[0039] In this embodiment, the forefoot portion 11 has a central hole 111, and the panel 2 is provided with a fastener 21 that engages with the central hole 111 to achieve a rotatable connection of the panel. The fastener 21 passes through the central hole 111 and is fixed by fastening or screwing to ensure that the panel does not fall off when rotating.
[0040] Example 3. One embodiment of a round fastener, such as... Figure 4-5As shown, the fastener 21 is an elastic element, the central hole 111 has an inner lip 112, the fastener 21 is a circular, protruding, tapered button, the button has a pressure cap 211, the outer diameter of the pressure cap 211 is larger than the inner diameter of the central hole 111.
[0041] In this embodiment, pressing the cap 211 deforms the elastic button, causing it to pass through the central hole. After release, the button's tapered portion locks into the inner lip 112, enabling quick installation. The panel 2 can rotate circumferentially relative to the forefoot 11. The elastic structure facilitates quick assembly and disassembly without tools, improving ease of use.
[0042] Example 4. Another embodiment of the round fastener, such as Figure 4 As shown, the fastener 21 consists of a circular hole 212 on the panel 2 and a plurality of arc-shaped insert pieces 213 arranged circumferentially on the inner wall of the circular hole 212. The arc-shaped insert pieces 213 are elastic members with an outer lip edge 214. The central hole 111 has an inner lip edge 112. The inner diameter of the circular hole 212 is equivalent to the inner diameter of the central hole 111.
[0043] In this embodiment, pressing the arc-shaped insert 213 deforms all the arc-shaped inserts 213, causing them to pass through the central hole 111. After release, the outer lip 214 of the insert 213 engages with the inner lip 112 of the central hole 111, achieving quick installation. A plurality of arc-shaped inserts 213 with inner lips 112 arranged circumferentially form a circumferential guide groove, allowing the panel 2 to rotate circumferentially relative to the forefoot portion 11. The elastic structure facilitates quick assembly and disassembly without tools, improving ease of use.
[0044] Example 5. This example illustrates the overall shape of the forefoot and panel, as shown below. Figure 1-8 As shown, the forefoot portion 11 and the panel 2 are both disc-shaped.
[0045] In this embodiment, both the forefoot portion 11 and the panel 2 are discs. This serves two purposes: firstly, it increases the adjustable area for foot width to accommodate the foot measurement needs of different age groups; secondly, it facilitates comparison of the reference position offset between the panel 2 and the forefoot portion 11.
[0046] Example 6. This example illustrates the mating structure between the panel and the forefoot, as follows: Figure 1-8 As shown, the forefoot portion 11 is generally shaped as a large disc with two ear portions 113 facing each other on both sides; The overall shape of the panel 2 is a small disc with a single ear 22 on one side; like Figure 8 As shown, when the single ear portion 22 of the panel 2 rotates by + / -90 degrees with the panel 2, the single ear portion 22 and the double ear portion 113 are coaxial.
[0047] In this embodiment, when the panel is rotated, the single ear 22 is aligned with the double ear 113, which can quickly locate the measurement angle of the left and right feet. The angle positioning is achieved by aligning the ears, avoiding human judgment errors, improving measurement efficiency, standardizing the rotation angle, ensuring that the measurement conditions of the left and right feet are consistent, and making the data highly comparable.
[0048] Example 7. This example illustrates the use of a limiting device to measure the left and right feet, such as... Figure 1-8 As shown, the forefoot portion 11 is provided with a limiting member to restrict further rotation of the single ear portion 22.
[0049] In one example, a limiting member is provided on the lower side of the bilateral ear portion 113. Figure 1-8 The limiting member shown is a protrusion 141, which restricts excessive rotation of the single ear portion 22. When the single ear portion 22 rotates to ±90 degrees, the limiting member contacts the single ear portion 22, preventing further rotation, preventing panel measurement misalignment, fixing the rotation range, and ensuring accurate measurement of foot length and width data.
[0050] Another example, such as Figure 11-12 As shown, the limiting component is a guide groove 142 inside a large circular disc. The guide groove is semi-circular, with one end at the zero position and the other end at the 6 o'clock position. The zero and 6 o'clock positions correspond to the alignment of the single ear 22 and the two double ears 113 on both sides, respectively. A retaining shaft 23 is located under the upper small circular disc, i.e., the panel 2. The retaining shaft 23 is inserted into the guide groove 142 and slides along it. When the retaining shaft 23 slides to the zero or 6 o'clock end of the guide groove 142, it is blocked by the end point, thus limiting the rotation range of the panel 2. When the single ear 22 rotates to +90 degrees, as... Figure 8 , Figure 11 As shown, the single ear portion 22 stops due to the guide groove, allowing for right foot measurement; when the single ear portion 22 rotates to -90 degrees, as... Figure 7 , Figure 12 As shown, the single ear part 22 is stopped by the guide groove, allowing for left foot measurement; the rotation range of the fixed panel ensures accurate measurement of foot length and width data.
[0051] Example 8. This example shows a foot length indicator, such as... Figure 1 , 6 as well as Figure 7 As shown, the foot length indicator 32 includes at least one of the following: a cross-shaped indicator or a chain-head-shaped indicator.
[0052] In this embodiment, the foot length indicator 32 is a cross-shaped indicator or a chain-head-shaped indicator, which facilitates accurate alignment with the toe endpoints. The cross-shaped indicator is suitable for cases where the toes are distinct, while the chain-head-shaped indicator can hook onto the edge of the toes to adapt to different foot shapes. The special shape of the indicator improves the positioning accuracy of the toe endpoints and reduces reading errors.
[0053] Example 9. This example shows a foot width indicator, such as... Figure 1 ,6 as well as Figure 7 As shown, the foot width indicator 43 is arranged perpendicularly to the lateral muscle retainer 42.
[0054] In this embodiment, the foot width indicator 43 is perpendicular to the lateral muscle retainer 42, ensuring that the indicator moves horizontally along the transverse groove 41 when the retainer is in contact with the outer side of the foot. The vertical setting makes the width measurement direction consistent with the lateral side of the foot, avoiding oblique errors. The vertical structure ensures the accuracy of the width measurement direction, and the data is more consistent with the actual foot width. It simplifies the operation process, and users do not need to make additional angle adjustments; they can simply slide the indicator to read the value.
[0055] Example 10. This example shows a medial muscle block, such as... Figure 1 , 6 as well as Figure 7 As shown, the medial muscle block 45 has an inner arc bend 451 that cooperates with the medial phalangeal muscle on the side closest to the lateral muscle block 42.
[0056] In this embodiment, the medial muscle stop 45 has an inner curved section 451 on the side near the lateral muscle stop 42, which matches the contour of the medial phalanx muscle. The inner curved section 451 fits snugly against the medial phalanx muscle at the back of the big toe, avoiding measurement gaps caused by a straight stop. The curved section precisely fits the physiological structure, eliminating measurement blind spots, resulting in more accurate foot width data, reducing repeated measurements due to non-fitting stops, and improving efficiency.
[0057] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
