Description

Technical Field

[0001] This utility model relates to an anti-friction device for women's shoes. Background Technology

[0002] Blistering in women's shoes is a common problem, primarily affecting the back of the ankle and the sides of the forefoot. Many factors contribute to this, including the shoe's structural design, such as a narrow forefoot area or a drop in heel height. To prevent design flaws from causing comfort issues (including blisters) in mass-produced shoes, samples are often made. Some larger companies even hire foot models—models with feet conforming to standard sizes—to try on shoes, provide fitting reports, and then evaluate and modify the design to create women's shoes that fit the foot perfectly and prevent blisters. In reality, the number of qualified foot models is extremely limited; often, only one in dozens is suitable. This is also a shortcoming of women's shoes produced by modern standard shoe manufacturing processes. Because standardized shoes have uniform standard sizes, their anti-friction assessment is aimed at standard-sized feet. However, standard-sized feet are actually very rare. Therefore, the anti-friction design considerations of this type of shoe do not really take into account the friction situation of most people. This is why many people experience friction after buying mass-produced women's shoes. Utility Model Content

[0003] In view of the above shortcomings, the purpose of this utility model is to provide an anti-friction device for evaluating the anti-friction design of women's shoes.

[0004] Therefore, the present invention provides a foot-protecting device for women's shoes, comprising a device body, which is a model of the foot and matches the shoe cavity of the women's shoes. The device body is provided with a detection component, which can detect the force between the outline edge of the device body and the corresponding inner surface of the shoe upper.

[0005] Furthermore, the detection components are located on both sides of the forefoot portion of the main body of the device, and at the rear and sides of the heel where they contact the heel counter.

[0006] Furthermore, the shape of the main body of the device can match the inner cavity of a standard-sized women's shoe.

[0007] Furthermore, the main body of the device can expand laterally and longitudinally, so that the size of the main body of the device can be larger than the inner cavity of the corresponding standard size women's shoe. The degree of lateral and longitudinal expansion of the main body of the device is between the corresponding standard size and the next adjacent standard size, which can be used to expand the shoe cavity of the standard size or to simulate the foot force between two adjacent standard sizes.

[0008] Furthermore, the main body of the device includes a forefoot portion and a heel portion. The forefoot portion and the heel portion of the main body of the device are provided with extension strips. The extension strips are extended longitudinally or laterally with the main body of the device and with the forefoot portion and the heel portion through connecting rods.

[0009] Furthermore, a connecting rod is fixed to one of the forefoot and heel portions and the extension strip, and the corresponding other portion is provided with a cavity and a through hole connected to the cavity. A limiting block is provided at the end of the connecting rod, and the connecting rod passes through the through hole so that the limiting block can move in the cavity.

[0010] Furthermore, the detection component is a miniature pressure gauge, which is disposed in the extension bar.

[0011] Furthermore, the extension strip is provided with stepped holes, and a pressure block matching the shape of the stepped holes is provided in the stepped holes. A micro pressure gauge is provided at the bottom of the pressure block, and the bottom of the micro pressure gauge is fixed in the extension strip.

[0012] Furthermore, the outer contour of the pressure block matches the arc of the contour line of the device body.

[0013] Furthermore, the outline of the pressure block protrudes slightly beyond the outline of the device body.

[0014] The beneficial technical effects of this utility model are as follows:

[0015] This utility model discloses an anti-friction device for women's shoes. By setting up a detection component, the detection component can detect the squeezing force between the shoe upper and the device body to determine whether the design cavity of the sample shoe is too tight, resulting in excessive squeezing force and causing friction.

[0016] In a specific embodiment of this utility model, by expanding laterally and longitudinally, it is possible to simulate non-standard size feet, assess the force exerted on the feet between two adjacent standard sizes, and make corresponding adjustments to the design and manufacturing process. This not only allows standard size feet to match the shoes, but also makes non-standard size feet more comfortable to wear and reduces the probability of blisters.

[0017] In a specific embodiment of this utility model, by expanding laterally and longitudinally, the shoe cavity that may rub against the feet can also be expanded, making it less likely to rub against the feet. Attached Figure Description

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] Reference Figures 1 to 4 As shown, this utility model discloses an anti-friction device for women's shoes, comprising a device body 1, which is a model of a human foot and matches the shoe cavity of the women's shoe. The device body 1 is equipped with a detection component that can detect the force between the outline of the device body 1 and the corresponding inner surface of the shoe upper. The device body 1 uses a standard-sized foot model, such as European or Chinese sizes. The detection component is set in areas of the foot prone to rubbing, such as the heel (corresponding to the ankle) and the sides of the forefoot (generally corresponding to the knuckles of the big toe and little toe). The detection component can be a miniature pressure gauge 11 or blue carbon paper, using the depth of the color after pressure to qualitatively determine the force, or a material that deforms under pressure, observing the depth of deformation to determine the force. In fact, this embodiment can detect abnormal force at corresponding locations, which are usually caused by the design or manufacturing of the corresponding location not conforming to ergonomics, or an unnatural transition between the front and back positions. Therefore, by adopting the device of this embodiment and correcting these shortcomings in design and manufacturing, the transition of the upper surface is smoother and fuller, the visual effect of the shoe upper is more natural, and it is more in line with the overall aesthetic of arts and crafts.

[0025] In the above embodiments, reference is made to Figures 1 to 3 As shown, the main body 1 of the device can expand laterally and longitudinally, allowing its size to exceed the inner cavity of a standard-sized women's shoe. The degree of lateral and longitudinal expansion of the main body 1 is between the corresponding standard size (e.g., European size 36) and the next adjacent standard size (e.g., European size 37), enabling it to expand the shoe cavity of a standard size or to simulate foot force between two adjacent standard sizes. (Refer to...) Figures 1 to 3As shown, the main body 1 of the device includes a forefoot portion 2 and a heel portion 3. The forefoot portion 2 and the heel portion 3 are separated into two independent parts at the arch of the foot, and are connected longitudinally by two connecting rods 5. Specifically, refer to... Figure 3 As shown, one of the forefoot portion 2 and the heel portion 3 is fixed to one end of the connecting rod 5, while the other has a rectangular cavity 8 and a straight through hole 7 connected to the cavity 8. The end of the connecting rod 5 has a limiting block 6, and the connecting rod 5 passes through the through hole 7, allowing the limiting block 6 to move within the cavity 8. The connecting rod 5 can be tightly fitted with the through hole 7, and the tight fit force can ensure stable position after being compressed by the shoe's inner cavity. Alternatively, the tight fit can be replaced with the following structures: First, the upper or lower surface of the connecting rod 5 can be serrated, and the upper or lower surface of the through hole 7 can be correspondingly serrated and detachably connected, such as by bolting the lower block to the heel portion 3; Second, one end of the connecting rod can be hinged, such as by providing two limiting blocks on both sides of the last's connection point, forming a rotatable connection structure. The other end of the connecting rod is threaded to the heel portion. Other locking structures can also be used.

[0026] In the above embodiments, reference is made to Figure 2 and Figure 3 As shown, the specific scheme for lateral expansion is as follows: an expansion strip 4 is provided at the forefoot portion of the main body 1. The expansion strip 4 is also laterally expanded to the main body 1 via a connecting rod 5. The connecting rod 5 and its connection relationship with the corresponding part are basically the same as the connecting rod structure between the forefoot portion 2 and the heel portion 3, and will not be described in detail here. Correspondingly, an expansion strip 4 can also be provided at the heel portion. This expansion strip 4 can be extended longitudinally without a connecting rod, and is mainly used for detecting the force on the heel. The miniature pressure gauge 11 of the detection component can be installed in the expansion strip 4. Specifically, a stepped hole 10 is provided in the extension strip 4, and a pressure block 9 matching the shape of the stepped hole 10 is provided in the stepped hole 10. The outer contour of the pressure block 9 matches the arc of the contour line of the device body 1, or the contour of the pressure block 9 slightly protrudes from the contour of the device body 1, so that the pressure block 9 can simulate the force situation of the position that is prone to foot chafing. A miniature pressure gauge 11 is provided at the bottom of the pressure block 9, and a base 12 is provided at the bottom of the miniature pressure gauge 11. The base 12 is fixed in the extension strip 4.
