Description

Technical Field

[0001] The utility model relates to a shoe heel. Background Art

[0002] Chinese patent document CN215532079U discloses a shoe heel, comprising a support body, a sponge layer, and a fabric layer; the support body is made of TPEE; the support body comprises a first side support portion, a second side support portion, and an arc-shaped tail support portion arranged between the first side support portion and the second side support portion; a through hole is provided in the upper and middle part of the tail support portion; the sponge layer comprises a fitting portion connected to the inner side of the support body and a support portion penetrated in the through hole and connected to the fitting portion; the fabric layer comprises an inner side fabric layer and an outer side fabric layer which are butt-jointed to form a filling cavity; the support body and the sponge layer are matchedly arranged in the filling cavity.

[0003] However, the above solution has poor ventilation effect and is not smooth enough when worn. Utility Model Content

[0004] The utility model aims to provide a shoe heel structure with good air permeability and smoother wearing.

[0005] The purpose of the utility model is achieved through the following technologies:

[0006] A shoe heel comprises a shoe heel body, and a raised portion adapted to the heel is formed on the inner side surface of the rear end of the shoe heel body. The characteristic is that at least one groove is formed on the inner side surface of the rear end of the shoe heel body, extending from the upper side of the raised portion to the lower side of the raised portion. The raised portion is used to prevent the heel from separating from the heel of the human body. After the user puts on the shoe, the air in the shoe can be discharged outside the shoe through the groove, and the air outside the shoe can also be inhaled through the groove, thereby achieving a ventilation effect and better air permeability. In addition, since the groove is provided on the raised portion, the user can wear the shoe more smoothly.

[0007] The raised portion extends along the width direction of the heel and gradually narrows from the middle to both sides, so that it can better fit the shape of the heel and the transition of the raised portion is smoother.

[0008] There are two grooves, which are symmetrical on the left and right, which can enhance breathability and make wearing smoother.

[0009] The width of the groove is 2-3 mm, and the depth is 2-3 mm. If the width and depth of the groove are too large, the heel of the shoe will easily separate from the heel. If the width and depth of the groove are too small, poor air permeability will result.

[0010] The heel body includes a support body, an inner side material layer, an outer side material layer and a sponge body. The inner side material layer, the sponge body, the support body and the outer side material layer are hot-pressed and compounded in sequence from the inside to the outside to form the heel body. The sponge body makes the inner side of the heel body bulge to form the bulge. The support body supports the heel and can prevent the heel from collapsing when the user wears the shoe. The inner side material layer, the sponge body, the support body and the outer side material layer are connected together by hot pressing, and the structure is very stable. The sponge body is elastic. When the user wears the shoe, the bulge can be elastically deformed to allow the heel to pass through. Since the groove is provided, the bulge can be more elastically deformed, and the user can wear it more smoothly.

[0011] The heel body includes a support body, an inner side material layer, an outer side material layer and a sponge body. The inner side material layer, the sponge body, the support body and the outer side material layer are hot-pressed and composited in sequence from the inside to the outside to form the heel body. The sponge body makes the inner side surface of the heel body bulge to form the bulge part, and the two grooves separate the sponge body into a first sponge body and two second sponge bodies located on both sides of the first sponge body.

[0012] The two grooves are curved extension structures, and being arranged as curved structures can better fit the protruding sponge body.

[0013] The support body includes a first support wing and a second support wing that are symmetrically arranged. The first support wing and the second support wing form an arc structure that wraps the heel, so that a large-area wrapping and supporting effect can be achieved for the heel.

[0014] The support body is made of TPEE. TPEE material has the advantages of bending resistance, heat resistance and long service life. Shoes without support bodies on the market are usually easily stepped on and collapsed by the heels when worn, and it is necessary to squat down to pull up the heels or use a shoe horn, which is not friendly to the elderly or people who have difficulty squatting. Using TPEE as the support body for the heels of shoes can overcome this problem, and the support body can well support the heels of shoes when worn.

[0015] A shoe comprises the above-mentioned heel. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Reference Figures 1 to 5 As shown, a shoe heel comprises a heel body, which is composed of an outer fabric layer 1, an inner fabric layer 2, a support body 3 and a sponge 4. The inner fabric layer 2, the sponge 4, the support body 3 and the outer fabric layer 1 are hot-pressed and compounded in sequence from the inside to the outside. The sponge 4 makes the inner side of the heel body bulge to form a bulge 6. The sponge 4 is specifically a sponge in this embodiment, and can also be other materials with elastic deformation effect such as silica gel, which is not limited here. Two grooves 5 symmetrically arranged and extending in an upper and lower arc shape are formed on the sponge 4, so that the air in the shoe can be discharged out of the shoe through the grooves 5 after the user wears it, and the air outside the shoe can also be inhaled through the grooves 5, so as to achieve the effect of ventilation and better air permeability. In addition, due to the provision of the grooves 5, the sponge 4 can be more easily deformed, and the user can wear it more smoothly. The width of the groove 5 is 2-3mm, and the depth is 2-3mm. If the width and depth of the groove 5 are too large, it is easy to cause the heel to separate from the heel. If the width and depth of the groove 5 are too small, it will cause poor air permeability.

[0022] The inner side material layer 2 is hot pressed onto the front end surface of the sponge 4 and fits with the groove 5, so that the inner side material layer 2 will not cover the groove 5 and affect the exhaust effect. The sponge 4 protrudes to form a ridge 6, which can make the human heel more comfortable and play a buffering role. The ridge 6 can prevent the heel from falling off after the user puts on the shoe, but the sponge 4 will have a certain obstruction when wearing shoes. The groove 5 is set on the sponge 4 to play a certain guiding role, and the sponge 4 can be better deformed, allowing the user to wear it better.

[0023] The two grooves 5 separate the spongy body 4 into a first spongy body 41 and two second spongy bodies 42 located on both sides of the first spongy body 41. The first spongy body 41 mainly plays a cushioning role on the back of the human heel and the Achilles tendon, and the second spongy body 42 plays a cushioning role on the side of the human heel, with a strong wrapping property. The raised portion 6 is arranged in this way, and it will extend along the width direction of the heel, gradually narrowing from the middle to both sides, which can better adapt to the shape of the heel, making the transition of the raised portion 6 smoother, and due to the separation effect of the two grooves 5, there is a gap between the first spongy body 41 and the second spongy body 42. When wearing, the heel will squeeze the spongy body 4, and the gap can provide the first spongy body 41 and the second spongy body 42 with space for deformation, making it smoother to wear.

[0024] The support body 3 includes a first support wing and a second support wing that are symmetrically arranged. The first support wing and the second support wing form an arc structure that wraps the heel, so that a large area of ​​wrapping support effect can be achieved for the heel. Figure 2As shown, the cross-section of the support body 3 in the middle of the heel is "S"-shaped, and the upper end of the "S"-shape protrudes into the shoe to achieve a supporting effect, and can cooperate with the sponge body 4 to prevent the heel from falling off after the user wears it. The lower end of the "S"-shape protrudes outside the shoe to achieve the effect of wrapping the human heel. The support body 3 is made of TPEE, which is thermoplastic polyester elastomer. TPEE has the elasticity of rubber and the strength of engineering plastics, and has the advantages of bending resistance, heat resistance and long service life. Usually, the heel of shoes on the market is not provided with a support body 3, which is easy to be stepped on and collapsed when worn, so that it is necessary to squat to pull up the heel, or use a shoe horn, which is inconvenient to operate and is not friendly to the elderly or people who have difficulty squatting. The utility model uses a support body 3 made of TPEE, which can solve this problem well. When wearing, you only need to put your foot into the shoe and step on the heel directly. The support body 3 can support the heel well and will not be stepped on and collapsed.

[0025] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of implementation of the present utility model. That is, equivalent changes and modifications made according to the scope of the patent application of the present utility model and the contents of the specification should still fall within the scope covered by the patent of the present utility model.
