Description

Technical Field

[0001] This utility model relates to the field of children's shoe technology, and more specifically, to a children's casual shoe with an expandable shoe body. Background Technology

[0002] Children's casual shoes are comfortable and lightweight shoes designed specifically for children, suitable for everyday wear and leisure activities. They are typically made of soft, breathable materials to ensure children feel comfortable while wearing them. They are usually designed with a certain support structure to protect children's feet and provide foot stability. The soles are usually made of abrasion-resistant materials to increase the durability of the shoes. They are adapted to children's active lifestyles, providing a comfortable wearing experience while meeting their needs for leisure and outdoor activities in their daily lives.

[0003] Chinese Patent Announcement No. CN218105037U discloses a children's casual shoe. This solution uses components such as a pressure plate, support column, and insole. Through the cooperation between the pressure plate, support column, and insole, the pressure plate can suppress the sole warping caused by prolonged washing by adjusting the spatial relationship. This achieves the effect of suppressing the deformation and increased forefoot warping of shoes worn for a long time through the pressure plate, support column, and insole. This solution addresses the issue of current children's casual shoes, which take into full consideration the growth and development of children, such as making the shoe shape wider, the heel lower, and the forefoot warping smaller, all of which are suitable for children's foot development.

[0004] Younger children are more active and playful. When learning to walk or playing, their unsteady gait makes them prone to kicking hard objects such as furniture, toys, or other objects with their toes, increasing the risk of injury. The above-mentioned solutions and children's shoes currently on the market do not provide adequate protection for the toes. Kicking hard objects can easily cause pain and discomfort, affecting children's learning to walk and activities.

[0005] Therefore, a children's casual shoe with an expandable upper is proposed to address the above problems. Utility Model Content

[0038] Please see Figures 1-7 An expandable children's casual shoe includes an upper sole 1 and a lower sole 2. Two fixing straps 5 are fixedly connected to the top of the upper sole 1, and a heel loop 4 is fixedly connected between the two fixing straps 5. A protective component 6 is provided at the outer end of the upper sole 1, and a reinforcing component 9 is provided between the upper sole 1 and the lower sole 2. The protective component 6 includes a cushioning device 61 and a one-way valve 63. An air tube 62 is connected to the outer end of the cushioning device 61. The one-way valve 63 and the cushioning device 61 are connected through the air tube 62. When worn, the cushioning device 61 abuts against the toe. The cushioning device 61 can change its volume.

[0039] The upper 3 is fixedly installed on the top of the sole 1, and the inner side of the heel ring 4 has an installation groove 8. The inner pad 7 is installed inside the installation groove 8 and is made of sponge.

[0040] The shoes in this design are primarily casual shoes for children to wear in summer. The semi-enclosed upper 3 increases overall breathability. The sole has a double-layer design, mainly composed of an upper sole 1 and a lower sole 2. The upper 3 is fixed to the toe section of the upper sole 1, covering only the forefoot. On both sides of the heel section of the upper sole 1, there are fixing straps 5, with a heel loop 4 fixed between the two straps 5. The fixing straps 5 are mainly for installing the heel loop 4, which is used to fit over the heel. On the user's ankle, a protective component 6 is installed at the toe area of ​​the upper 3 and the upper sole 1. The cushioning device 61 contains an inflatable air bladder 611. Through the cushioning effect of the air bladder 611, when the foot kicks a hard object, the toe will come into contact with the cushioning device 61, and the cushioning device 61 can play a cushioning role to protect the child's toe. At the same time, since the cushioning device 61 can change its volume by inflating, the shoe size can be finely adjusted so that the shoe can better fit different sizes of feet.

[0041] A fixing cavity 10 is formed on the lower sole 2, and a reinforcing component 9 is installed inside the fixing cavity 10, which is located between the upper sole 1 and the lower sole 2. The reinforcing component 9 has multiple functions. The friction block 92 fixed at the bottom of the fixing plate 91 extends to the bottom of the lower sole 2. The friction block 92 can increase the friction between the forefoot and the ground, making it less likely for children to slip when walking. A support plate 98 is set between the sole plate 95 and the pressure plate 96. The support plate 98 can not only support the heel, but also undergo slight deformation through the wave-shaped structure, which can play a certain role in cushioning.

[0042] On the inner side of the rear half of the heel ring 4, that is, at the foot tendon, there is an installation groove 8. An inner pad 7 can be installed on the inner side of the installation groove 8 with glue. The inner pad 7 is made of soft sponge and directly contacts the foot tendon, which can reduce friction and improve comfort when walking.

[0043] Please see Figure 3 and Figure 4 The cushioning device 61 includes an airbag 611, a fabric layer 612, and a connecting layer 613. The connecting layer 613 is connected to the air tube 62. The fabric layer 612 covers the outer surface of the airbag 611. The connecting layer 613 is installed on the outer surface of the fabric layer 612 and is connected to the inner side of the upper 3 and the top of the upper sole 1.

[0044] The air tube 62 is embedded inside the upper sole 1, and the one-way valve 63 is fixedly installed on the outside of the upper sole 1. The airbag 611 is inflated and deflated by the one-way valve 63 to change its volume.

[0045] The cushioning device 61 in this design is mainly composed of an air bladder 611, a fabric layer 612, and a connecting layer 613. The air bladder 611 can be inflated and deflated, changing its volume. The fabric layer 612, which surrounds the cushioning device 61, protects the air bladder 611. The fabric layer 612 is made of elastic fabric and can expand and contract with the air bladder 611. The fabric layer 612 is in direct contact with the toe, improving foot feel. A semi-circular connecting layer 613, made of rubber, is wrapped around the fabric layer 612 and is mainly used to install the cushioning device 61. The connecting layer 613 is bonded to the shoe upper 3 with adhesive. The air bladder 611 is fixed to the outside of the upper sole 1. An air tube 62 is connected to the outside of the air bladder 611. The air tube 62 is connected to the inside of the air bladder 611. At the same time, the inside of the upper sole 1 is provided with holes so that the air tube 62 can be pre-embedded through the inside of the upper sole 1. A one-way valve 63 is fixedly installed on the outside of the upper sole 1. The tail of the one-way valve 63 is connected to the air tube 62 and is fixed inside the upper sole 1. The head of the one-way valve 63, that is, the inflation / deflation end, extends out of the side of the upper sole 1. The one-way valve 63 is a universal type and can be inflated or deflated by an air pump. The air bladder 611 can be inflated or deflated through the one-way valve 63 and the air tube 62.

[0046] When a user wears these casual shoes, their toes rest against the outside of the cushioning device 61. When kicking a hard object, the cushioning device 61 is relatively soft, and the toes are cushioned and protected when they hit it, preventing pain. This can protect children's toes. At the same time, the cushioning device 61 can change its volume, meaning the overall shoe size can be finely adjusted to expand or shrink the internal space of the shoe, making the shoe more suitable for different foot shapes and improving wearing comfort.

[0047] Please see Figure 2 and Figures 5-7 The reinforcing component 9 includes a fixing plate 91, with multiple friction blocks 92 fixedly connected to the bottom end of the fixing plate 91. A fixing cavity 10 is opened at the outer end of the lower shoe sole 2, and multiple through holes 11 are opened at the bottom end of the fixing cavity 10. The friction blocks 92 extend to the shoe sole through the through holes 11, and the fixing plate 91 is fixedly installed inside the fixing cavity 10.

[0048] The reinforcing component 9 also includes a limiting frame 94, which is connected to the inside of the fixing cavity 10. The fixing piece 91 and the limiting frame 94 are connected by multiple connecting straps 93. A base plate 95 is installed inside the limiting frame 94, and a support plate 98 is installed on the top of the base plate 95. The support plate 98 is wavy.

[0049] The reinforcing component 9 also includes a pressure plate 96, with two rubber blocks 97 fixedly installed at the bottom of the pressure plate 96. The bottom of the pressure plate 96 abuts against the support plate 98, and the bottom of the rubber blocks 97 abuts against the base plate 95.

[0050] The reinforcing component 9 in this design is installed between the upper sole 1 and the lower sole 2, which can enhance the strength and functionality of the upper sole 1 and the lower sole 2. The fixing plate 91 and the limiting frame 94 are both fixed to the fixing cavity 10 opened in the upper sole 1 with adhesive. The fixing plate 91 is located at the forefoot position, while the limiting frame 94 is located at the heel position. The fixing plate 91 and the limiting frame 94 are connected by the limiting frame 94. The connecting strap 93 is made of soft rubber strip. When walking, the forefoot will... The arch of the foot is bent, but the connecting strap 93 can prevent it from affecting normal walking. A friction block 92 is fixed to the bottom of the fixing plate 91. The friction block 92 has anti-slip texture on the outside and multiple through holes 11 are opened inside the fixing cavity 10. The friction block 92 can pass through the through holes 11, so that the friction block 92 can directly contact the ground. Since the forefoot is the last to leave the ground when walking, the friction block 92 increases the friction, which can prevent slipping when the forefoot leaves the ground and improve the anti-slip effect.

[0051] A base plate 95 is provided inside the limiting frame 94, and the base plate 95 abuts against the bottom of the fixed cavity 10. A support plate 98 is installed on the top of the base plate 95. The support plate 98 can be glued. A pressure plate 96 covers the top of the support plate 98. Both the pressure plate 96 and the support plate 98 are made of high-toughness plastic. Two rubber blocks 97 are fixed at the bottom of the pressure plate 96. The rubber blocks 97 abut against the base plate 95. At the same time, the height of the rubber blocks 97 is the same as the thickness of the support plate 98, so as to reduce the force on the support plate 98 when it is stationary. The heel can be supported by the rubber blocks 97 and the support plate 98.

[0052] When a user jumps and lands, their heel is the main point of impact. Since the support plate 98 is wave-shaped, it has a certain deformation function. The pressure plate 96 presses down on the support plate 98, and the support plate 98 extends to both sides after being pressed, which can play a certain role in cushioning. Through the cooperation of the support plate 98 and the pressure plate 96, support and a certain cushioning effect can be achieved, which improves the protection of the heel during exercise.

[0053] Working principle: When the user wears the casual shoes, the toes will rest against the outside of the cushioning device 61. When the user kicks a hard object, the toes will be cushioned and protected by the cushioning device 61, which protects the child's toes. At the same time, since the cushioning device 61 can change its volume to expand or shrink the space inside the shoe, the shoe can better fit different foot shapes.

[0054] A friction block 92 is fixed at the bottom of the fixed plate 91 and directly contacts the ground. The friction block 92 increases the friction, which can improve the anti-slip effect of the forefoot. The height of the rubber block 97 is the same as the thickness of the support plate 98. The rubber block 97 and the support plate 98 can support the heel. When the user jumps and lands, the pressure plate 96 presses down on the support plate 98. After being pressed, the support plate 98 extends to both sides, which can play a certain cushioning role and improve the protection of the heel during exercise.
