Description

Technical Field

[0001] This utility model relates to the field of safety shoes, specifically to a safety shoe with adaptive arch support. Background Technology

[0002] Safety shoes, as essential products for ensuring foot safety, have long been widely used in high-risk work environments such as industrial production and construction. These footwear typically possess basic safety functions such as impact resistance, puncture resistance, and insulation; however, their structural design often focuses on external protection, lacking targeted optimization for arch support. Traditional safety shoes often employ fixed arch support structures, making it difficult to adapt to the diverse arch shapes of different users, leading to insufficient support or excessive pressure during wear.

[0003] Existing safety shoes generally lack an adjustment mechanism in their arch support systems. The support height and curvature are fixed at the factory, making dynamic adjustment impossible based on actual usage needs. This fixed structure results in a one-size-fits-all arch support effect, failing to meet the needs of individuals with flat feet or high arches, and also struggling to adapt to changes in foot shape caused by prolonged standing or walking. While some products attempt to achieve adjustment by adding removable pads, this requires disassembling the insole or even the sole, making the adjustment process cumbersome and difficult to achieve micron-level precision. Furthermore, the lack of a reliable positioning mechanism to ensure structural stability after adjustment leads to support failure or displacement during actual use, which can exacerbate foot fatigue. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned deficiencies and provide a safety shoe with adaptive arch support. This solves the technical problem that existing technologies cannot meet the adaptation needs of people with special foot types such as flat feet or high arches, and are also difficult to adapt to changes in foot shape caused by prolonged standing or walking for the same user.

[0005] The purpose of this utility model is achieved by the following method: a safety shoe with adaptive arch support, comprising a sole, a shoe body and an anti-impact surface, wherein the shoe body is disposed at the upper end of the sole and the anti-impact surface is embedded at the upper end of the shoe body.

[0006] The inner cavity of the sole is provided with an arch adjustment mechanism. The inner cavity of the sole has an adjustment groove. The arch adjustment mechanism includes an arch height adjustment elastic plate and a first height adjustment wedge. The arch height adjustment elastic plate is disposed inside the adjustment groove. A second height adjustment wedge is connected to both sides of the bottom of the arch height adjustment elastic plate.

[0007] The first height adjustment wedge is disposed on both sides of the arch height adjustment elastic plate. An adjustment arm is connected to the outside of the first height adjustment wedge. An adjustment fixing block is disposed outside the adjustment arm. An adjustment fixing ring is sleeved on the outside of the adjustment arm. The adjustment fixing ring is embedded in the outer sides of the sole. An adjustment groove is formed on the outside of the adjustment fixing ring, and an adjustment fixing groove is formed in the inner cavity of the adjustment fixing ring.

[0008] When adjusting the arch support height, the adjustment arm moves the first height adjustment wedge to move on both sides of the arch support adjustment plate. Because the inclined surfaces of the first and second height adjustment wedges engage, the movement of the first wedge compresses the second wedge, thus pushing the arch support adjustment plate up and down within the adjustment groove, adjusting the arch support height. During adjustment, the adjustment fixing block slides within the adjustment groove; once adjusted, it engages with the adjustment fixing groove to secure it. The result is personalized adjustment based on the arch height of different users, enhancing the fit of foot support and reducing fatigue during prolonged wear.

[0009] Furthermore, at least four sets of the adjusting fixing blocks and adjusting slides are provided, and they are respectively located on the outside of the adjusting fixing ring and the adjusting arm.

[0010] Multiple sets of adjusting blocks and adjusting slides work together to limit and guide the adjusting arm from multiple positions as it moves. This prevents the adjusting arm from tilting or wobbling during movement, ensuring the stability and accuracy of the arch support mechanism. It also enhances the stability after adjustment, preventing accidental changes in support height during use.

[0011] Furthermore, the bottom two sides of the foot arch height adjusting elastic plate are provided with sliders, which are slidably disposed inside the adjusting groove.

[0012] The sliding engagement between the slider and the adjustment groove restricts the movement direction of the arch height adjustment spring plate, allowing it to move vertically up and down only along the adjustment groove, thus preventing horizontal deviation. This ensures precise adjustment of the arch height adjustment spring plate, guarantees accurate arch support position, reduces frictional wear between the spring plate and the adjustment groove, and extends the service life of the arch adjustment mechanism.

[0013] Furthermore, a shoelace is inserted at the top of the shoe body, and a metal protective ring is provided between the shoelace and the shoe body.

[0014] The metal protective ring is placed where the shoelaces pass through the shoe body, transforming the direct friction between the shoelaces and the shoe body into friction between the shoelaces and the metal protective ring. This prevents repeated pulling of the shoelaces from causing wear and tear at the perforations, extending the shoe's lifespan. Simultaneously, the metal protective ring helps maintain the shape of the perforations, making it easier to distribute force when the shoelaces are tightened, thus improving the shoe's support and adjustment for the foot.

[0015] Furthermore, the inner cavity of the shoe body is provided with a shoe tongue, and the inner cavity of the shoe tongue is embedded with a soft pad.

[0016] The padding has a certain degree of elasticity and cushioning, conforming to the instep and distributing pressure through its own deformation when the tongue is pulled by the laces. This reduces pressure on the instep when the laces are tightened, improves comfort at the top of the foot, and enhances the fit between the tongue and the instep, preventing the tongue from shifting during walking and ensuring stability.

[0017] Furthermore, the bottom of the shoe sole is uniformly provided with anti-slip blocks, and the bottom of the anti-slip blocks is provided with anti-slip texture.

[0018] Anti-slip blocks increase the contact friction between the sole and the ground, while anti-slip patterns further increase the coefficient of friction between the sole and the ground, especially on wet or rough surfaces, where the patterns can store or drain liquids and debris from the contact surface.

[0019] The beneficial effects of this utility model are:

[0020] This safety shoe with adaptive arch support features an arch adjustment mechanism within the sole cavity, allowing for flexible adjustment of the arch support height to accommodate different user arch shapes and needs, thus improving fit and comfort. The arch height adjustment elastic plate, along with first and second height adjustment wedges, allows for adjustment of the arch support height by moving the adjustment arm within the adjustment fixing ring. During adjustment, the adjustment fixing block and adjustment fixing groove secure the position of the adjustment arm, ensuring stability after adjustment. Simultaneously, the adjustment groove facilitates operation of the adjustment arm, making the adjustment process more convenient. This structural design, while providing safety features such as impact protection, enhances adaptive arch support, reduces fatigue from prolonged wear, and improves the overall user experience.

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0027] In this embodiment, refer to Figures 1-4 Specifically, a safety shoe with adaptive arch support includes a sole 1, a shoe body 3, and an anti-impact surface 4. The shoe body 3 is located at the upper end of the sole 1, and the anti-impact surface 4 is embedded at the upper end of the shoe body 3.

[0028] The inner cavity of the sole 1 is provided with an arch adjustment mechanism 2. The inner cavity of the sole 1 is provided with an adjustment groove. The arch adjustment mechanism 2 includes an arch height adjustment elastic plate 27 and a first height adjustment wedge 25. The arch height adjustment elastic plate 27 is disposed inside the adjustment groove. The bottom sides of the arch height adjustment elastic plate 27 are connected to second height adjustment wedges 26.

[0029] The first height adjustment wedge 25 is disposed on both sides of the arch height adjustment elastic plate 27. An adjustment arm 28 is connected to the outside of the first height adjustment wedge 25. An adjustment fixing block 22 is disposed on the outside of the adjustment arm 28. An adjustment fixing ring 21 is sleeved on the outside of the adjustment arm 28. The adjustment fixing ring 21 is embedded on both sides of the outside of the sole 1. An adjustment groove 23 is formed on the outside of the adjustment fixing ring 21. An adjustment fixing groove 24 is formed in the inner cavity of the adjustment fixing ring 21.

[0030] When the arch support height needs to be adjusted, the adjusting arm 28 is moved, causing the first height adjusting wedge 25 to move on both sides of the arch height adjusting elastic plate 27. Because the inclined surfaces of the first and second height adjusting wedges 25 and 26 cooperate with each other, the movement of the first wedge 25 compresses the second wedge 26, thereby pushing the arch height adjusting elastic plate 27 up and down within the adjusting groove, thus adjusting the arch support height. During adjustment, the adjusting fixing block 22 slides within the adjusting groove 23, and after adjustment, it can be engaged with the adjusting fixing groove 24 to complete the fixation. The achieved effect is personalized adjustment according to the arch height of different users, enhancing the fit of foot support and reducing fatigue during prolonged wear.

[0031] At least four sets of adjusting slide 23 and adjusting fixing block 22 are provided, and are respectively located on the outside of adjusting fixing ring 21 and adjusting arm 28.

[0032] Multiple sets of adjusting fixing blocks 22 cooperate with adjusting slides 23 to limit and guide the adjusting arm 28 from multiple positions when it moves. The effect is to prevent the adjusting arm 28 from tilting or wobbling during movement, ensuring the stability and accuracy of the arch adjustment mechanism 2 during adjustment, while also enhancing the fixing strength after adjustment to prevent accidental changes in support height during use.

[0033] The bottom sides of the foot arch height adjusting elastic plate 27 of the adjusting groove 23 are provided with sliders, which are slidably set inside the adjusting groove.

[0034] The sliding engagement between the slider and the adjustment groove restricts the movement direction of the arch height adjustment elastic plate 27, allowing it to move vertically up and down along the adjustment groove, thus preventing horizontal deviation. This ensures precise adjustment of the arch height adjustment elastic plate 27, guarantees accurate arch support position, reduces frictional wear between the elastic plate and the adjustment groove, and extends the service life of the arch adjustment mechanism 2.

[0035] The top of the shoe body 3 is fitted with a shoelace 32, and a metal protective ring is provided between the shoelace 32 and the shoe body 3.

[0036] A metal protective ring is fitted at the point where the shoelace 32 passes through the shoe body 3, transforming the direct friction between the shoelace 32 and the shoe body 3 into friction between the shoelace 32 and the metal protective ring. This prevents repeated pulling of the shoelace 32 from causing wear at the perforations of the shoe body 3, extending the lifespan of the shoe body 3. Simultaneously, the metal protective ring maintains the stable shape of the perforations, making it easier to apply force when the shoelace 32 is tightened, thus improving the shoe body 3's ability to provide a snug fit and adjust to the foot.

[0037] The shoe body 3 has an inner cavity with a tongue 31, and the inner cavity of the tongue 31 is fitted with a soft pad.

[0038] The padding has a certain degree of elasticity and cushioning, conforming to the instep area. When the tongue 31 is pulled by the laces 32, it distributes the pressure through its own deformation. The effect is to reduce the pressure on the instep when the laces 32 are tightened, improve the comfort of the top of the foot, and enhance the fit between the tongue 31 and the instep, preventing the tongue 31 from shifting during walking and ensuring stability when wearing the shoe.

[0039] The bottom of the shoe sole 1 is evenly provided with anti-slip blocks 11, and the bottom of the anti-slip blocks 11 is provided with anti-slip texture.

[0040] The anti-slip block 11 increases the contact friction between the sole 1 and the ground, while the anti-slip pattern can further increase the coefficient of friction between the sole 1 and the ground. Especially on wet or rough ground, the pattern can store or discharge liquids and debris from the contact surface.

[0041] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
