Description

Technical Field

[0001] The present invention relates to the field of shoe design, and particularly to a shoe device and a shoe that are convenient for putting on shoes, which are particularly suitable for the elderly and those with limited mobility. Background Art

[0002] Currently, the design of traditional shoes often requires the user to bend down or manually assist when wearing them. Especially for the elderly, pregnant women, those with back problems, children who are too late to lift the shoes, and people with limited mobility, this way of putting on shoes is particularly inconvenient and laborious.

[0003] For example, a footwear article provided in application number CN202290000225 includes a heel cup, which is attached to the upper and extends from the sole structure to at least a part of the rear heel collar of the upper. The heel cup is uniformly molded with an upper part, a middle part, and a lower part, and the upper part has an inner-outer length smaller than that of the middle part, and the middle part and the lower part form a concave structure configured to accommodate the heel. When the user wears the footwear, the upper part can deform from a first configuration to a second configuration under the load of the user's foot. In the second configuration, at least a part of the upper part is lowered relative to the first configuration and can return to the first configuration after the load on the user's foot is removed. The middle part includes a peripheral part thicker than the central part.

[0004] Although this special-shaped and structured heel cup can manufacture some shoes that are convenient to wear, there is no precedent for improving existing ordinary shoes into shoes that are convenient to put on and take off. Therefore, it is of great significance to design a device that is simple in structure, low in cost, convenient to use, and strong in adaptability for easy entry into shoes, so that existing shoes can be worn without manual assistance and without bending down. Summary of the Invention

[0005] The object of the present invention is to provide a shoe device and a shoe that are convenient for putting on shoes. Through reasonable design, the user can easily put on the shoes without bending down and without using hands, thereby improving the convenience and comfort of putting on shoes.

[0006] To achieve the above object, the present invention provides the following technical solution: A shoe device and a shoe that are convenient for putting on shoes. The shoe includes a shoe upper part composed of a shoe mouth and the subsequent shoe back part, an insole part, a midsole part, a shoe sole part, and an entry device.

[0007] Preferably, the entry device is composed of a heel part and a fixing plate part.

[0008] Preferably, the rear part of the insole is composed of an epidermal material wrapping a cushioning material and a shaping shell. The epidermal material is made of highly wear-resistant fabric or leather to extend the service life and enhance comfort. It is composed of a durable fabric and a soft sponge material wrapping. The cushioning material, such as sponge, can provide sufficient cushioning and support.

[0009] Preferably, the rear part includes an upper part, a middle part, and a lower part.

[0010] Preferably, the upper part of the shaping shell extends rearward in an upward direction to form an extension part corresponding to the upper part of the insole.

[0011] Preferably, the extension part is designed with a lower middle and a higher outer edge, and its longitudinal side view section extends in a slightly arc shape in a backward and upward direction. The extension part serves as a support for the upper part of the insole. Its design inspiration comes from the convex shape at the bottom of the heel, aiming to imitate the shape of the heel, enabling the upper part of the insole to better receive and disperse the pressure of the heel, thereby providing better support and stability. This slightly arc-shaped design not only ensures that there is no sense of the heel getting stuck during stepping, but also greatly improves the wearing comfort and reduces the discomfort to the foot.

[0012] Preferably, the lower part of the shaping shell is designed as a semi-circular part imitating the shape of the heel, corresponding to the lower part of the insole. This design inspiration comes from the natural shape of the heel, enabling the insole to completely wrap the heel, thereby effectively improving the stability and comfort of the shoe.

[0013] Preferably, a smooth transition part is provided between the extension part and the semi-circular part, corresponding to the middle part of the insole. The smooth transition part serves as a support for the middle part of the insole, achieving a smooth transition between the upper part and the lower part of the insole. Its main function in the process of putting on shoes is to enable the heel to smoothly enter the shoe cavity, thereby increasing the wearing comfort and convenience. Through this design, the heel can smoothly slide into the shoe interior, avoiding friction or obstruction with the back of the shoe, and improving the smoothness and comfort of putting on shoes.

[0014] Preferably, the extension part, the semi-circular shaping shell, and the smooth transition part have a uniform body thickness and gradually thin from the bottom to the outer edge.

[0015] Preferably, the smooth transition part is an open arc structure, and the horizontal width of the smooth transition part is smaller than the width of the human heel.

[0016] Preferably, the shaping shell has a certain support strength and elasticity. When the external force exceeds its support strength, the shaping shell will deform, but when the external force is less than its support strength, the shaping shell will recover and maintain its original shape. As the support body of the foot-in device, during the process of putting on shoes, when the heel steps on with force, the smooth transition part inside the middle part of the shaping shell will be stressed and deformed and expand outwards. This deformation enables the heel to smoothly slide into the lower part, achieving the action of putting on shoes without the assistance of hands. When the heel slides into the lower part, the expansion force acting on the smooth transition part will disappear instantly, and at the same time, the smooth transition part will instantly recover its original shape due to the resilience. This design enables the smooth transition part to hold the heel and makes it not easy to be pulled out, thus achieving the effect that the shoes are not easy to fall off..

[0017] According to an embodiment of the present invention, when the upper end of the foot-in device is stepped on with force by the heel, an inclined upper end part is designed. This design enables the heel to slide down along the inclined part, and at the same time makes the elastic middle part expand, so as to smoothly slide into the lower part, and can also achieve the action of putting on shoes without the assistance of hands. When the heel slides into the lower part, the expansion force acting on the smooth transition part will disappear instantly, and at the same time, the smooth transition part will instantly recover its original shape due to the resilience. This design enables the smooth transition part (i.e., the middle part) to hold the heel and makes it not easy to be pulled out, thus also achieving the effect that the shoes are not easy to fall off.

[0018] Preferably, a connecting extension part extends from the bottom of the semi-circular part. The thickness of the connecting extension part is less than the average thickness of other parts of the shaping shell and can be bent and deformed.

[0019] Preferably, the fixing plate part is made of high-strength and lightweight materials and has good support and elasticity.

[0020] Preferably, the fixing plate is designed as a cuttable structure, and its front part can be cut according to the actual needs of different shoes to adapt to shoes of different sizes, so as to ensure the versatility and adaptability of the device; its rear part is semi-circular, and the shape and size are consistent with the bottom shape of the semi-circular part.

[0021] Preferably, the rear end of the fixing plate part is embedded in the bottom arc of the semi-circular part, and a whole device is formed with the connecting extension part by sewing or gluing.

[0022] Preferably, at the bottom of the heel part, the skin material and the wrapped buffer material of the heel part are connected to the shaping shell as a whole by sewing or gluing.

[0023] Preferably, insert the foot insertion device above the insole inside the shoe, with the heel part close to the back of the shoe, and the upper end part protruding upward in an arc shape beyond the back of the shoe. The user can gently slide the heel into the shoe from the upper end part of the heel part, and then smoothly put the foot into the shoe without bending down or using hand assistance.

[0024] Preferably, the foot insertion device is suitable for shoes made by various shoe-making processes, including but not limited to: adhesive process, sewing process, molding process, injection molding process, vulcanization process, Goodyear process, overwrap process, etc. These manufacturing processes can be selected according to the characteristics of the materials, the availability of production equipment and different production requirements. As long as the foot insertion device can be effectively fixed inside the shoe, the effect of easy wearing and not easy to fall off can be achieved.

[0025] Preferably, the foot insertion device is especially suitable for the elderly, the disabled, children who have no time to lift the shoes, and other people who cannot conveniently bend down to put on shoes. By putting this device into various daily shoes, the convenience and comfort of putting on shoes can be significantly improved. At the same time, due to the cuttable design of the insole, this device can adapt to various types and sizes of shoes, and has a wide application prospect. Brief Description of the Drawings

[0036] The following will describe the detailed embodiments of the present invention with reference to the accompanying drawings.

[0037] In Embodiment 1 of the present invention, referring to Figure 1 shown is a shoe 11 equipped with the foot - entry - facilitating shoe device 1 of the present invention, which includes a shoe upper part 11 composed of a shoe mouth 110 and a subsequent shoe counter 111, an insole part 12, a midsole part 13, a sole part 14, and a foot - entry device 15.

[0038] In this embodiment, referring to Figure 2 , Figure 3 shown, the foot - entry device 15 is composed of a heel part 150 and a fixing plate part 151.

[0039] In this embodiment, referring to Figure 4 , the outer skin material 1500 of the heel part 150 wraps the buffer material 1501 and the shaping shell 1600. The outer skin material 1500 is made of highly wear - resistant fabric or leather to extend the service life and enhance comfort. It is composed of a durable fabric and a soft sponge material wrapping. The buffer material 1501, such as sponge, can provide sufficient buffering and support.

[0040] In this embodiment, referring to Figure 2 , the heel part 150 includes an upper part 151, a middle part 152, and a lower part 153.

[0041] In this embodiment, referring to Figure 5 , the shaping shell 1600 extends rearward in the upward direction at the upper part to form an extension part 1601, corresponding to the upper part 151 of the foot - entry device 15.

[0042] The extension part 1601 of this embodiment is designed with a lower middle part and a higher outer edge, and its side - view longitudinal section extends in a slightly arc - shaped manner in the backward - upward direction. The extension part 1601 serves as a support for the upper part 151 of the foot - entry device 15. Its design inspiration comes from the convex shape at the bottom of the heel, aiming to imitate the shape of the heel so that the upper part of the foot - entry device 15 can better receive and disperse the pressure of the heel, thereby providing better support and stability. This slightly arc - shaped design not only ensures that there is no sense of strangulation when stepping on the heel, but also greatly improves the wearing comfort and reduces the discomfort to the foot.

[0043] In this embodiment, referring to Figure 5, the lower part of the shaping shell 1600 is designed as a semi-circular part 1602 that mimics the shape of the heel, corresponding to the lower part 153 of the foot-in device 15. This design inspiration comes from the natural shape of the heel, enabling the foot-in device 15 to fully wrap around the heel, thus effectively improving the stability and comfort of the shoe 1.

[0044] In this embodiment, referring to Figure 5 , a smooth transition part 1603 is provided between the extension part 1601 and the semi-circular part 1602, corresponding to the middle part 152 of the foot-in device 15. The smooth transition part 1603 serves as a support for the middle part 152 of the foot-in device 15, achieving a smooth transition between the upper part 151 and the lower part 153 of the foot-in device 15. The main function of its design is to enable the heel to smoothly enter the shoe cavity during the shoe-wearing process, thereby increasing the comfort and convenience of wearing. Through this design, the heel can smoothly slide into the interior of the shoe 1, avoiding friction or obstruction with the rear shoe upper 111, and improving the smoothness and comfort of putting on the shoes.

[0045] In this embodiment, the thicknesses of the extension part 1601, the semi-circular shaping shell 1600, and the smooth transition part 1603 are uniform.

[0046] In this embodiment, the shaping shell 1600 is made of a resin material with a certain support strength and resilient elasticity. This material has elasticity and toughness, can deform under external force, but when the external force is less than its support strength, it can recover and maintain its original shape. In the selection of the resin material, it is recommended to choose new high-elasticity materials such as TPU (polyurethane), TPE (thermoplastic elastomer), or TPEE (thermoplastic polyester elastomer), etc. These materials have good elasticity and toughness, can provide sufficient support strength, and have the advantages of wear resistance, durability, and high temperature resistance. Therefore, choosing the shaping shell 1600 made of these new high-elasticity materials can effectively meet the structural requirements of the shoe 1 while ensuring wearing comfort and durability.

[0047] In this embodiment, referring to Figure 5 , the smooth transition part 1603 is designed as an open arc structure, and its horizontal width is smaller than the width of the human heel. This design can better fix the heel, improve the comfort and stability of wearing, and reduce the possibility of falling off. Because the width of the smooth transition part 1603 is smaller than the width of the heel, it can fit more closely to the foot, effectively preventing the shoe 1 from slipping or falling off during use. Such a design not only increases the comfort of wearing but also provides better safety and stability, bringing a more pleasant and reassuring shoe-wearing experience to users.

[0048] According to the embodiments of the present invention, referring to Figure 6 , Figure 7, the shaping shell 1600 has a certain supporting strength and elasticity. When the external force exceeds its supporting strength, the shaping shell 1600 will deform, but when the external force is less than its supporting strength, the shaping shell 1600 will recover and maintain its original shape. The shaping shell 1600 serves as the support of the foot-entering device 15 and plays an important role during the shoe-wearing process. When the heel steps on the shoe with force, the smooth transition part 1603 inside the middle part 152 of the shaping shell 1600 will be stressed and deformed and expand outwards. This deformation enables the heel to smoothly slide into the lower part 153, realizing the shoe-wearing action without the assistance of hands. When the heel slides into the lower part 153, the expanding force acting on the smooth transition part 1603 will disappear instantly, and at the same time, the smooth transition part 1603 will instantly return to its original shape due to the resilience. This design enables the smooth transition part 1603 to hold the heel in place and makes it difficult to pull out, thus achieving the effect that the shoes are not easily shed.

[0049] According to some other embodiments of the present invention, when the upper end of the foot-entering device 15 is stepped on by the heel with force, an inclined upper end part 151 is designed. This design enables the heel to slide down along the inclined part and at the same time expands the elastic middle part 152, referring to Figure 7 , so as to smoothly slide into the lower part 153, and can also realize the shoe-wearing action without the assistance of hands. When the heel slides into the lower part 153, the expanding force acting on the smooth transition part 1603 will disappear instantly, and at the same time, the smooth transition part 1603 will instantly return to its original shape due to the resilience. This design enables the smooth transition part 1603 (i.e., the middle part 152) to hold the heel in place and makes it difficult to pull out, thus achieving the effect that the shoes are not easily shed. These structural designs not only achieve quick wearing but also prevent the shoes from falling off, fully reflecting the novelty and creativity of the present invention.

[0050] According to the embodiments of the present invention, the bottom of the semi-circular part 1602 of the foot-entering device 15 is a horizontal plane and extends out a connecting extension part 1604, whose thickness is less than the average thickness of other parts of the shaping shell 1600, and. Through this design, the occupied space of the device inside the shoe 1 can be effectively reduced, ensuring the overall comfort and wearing experience of the shoe 1.

[0051] According to an embodiment of the present invention, the fixed plate portion 151 is made of a high-strength and lightweight material. Optional materials include thermoplastic polyurethane (TPU), thermoplastic elastomer (TPE), thermoplastic polyester elastomer (TPEE), ethylene-vinyl acetate copolymer (EVA), glass fiber reinforced plastic (GFRP), carbon fiber composite material, nylon (PA), high-density cardboard, etc., or a combination thereof. These materials have their respective advantages, such as high strength, good elasticity, lightweight, wear resistance, chemical corrosion resistance, etc., and can provide good support and comfort for the foot-in device 15. In particular, high-density cardboard, as a lightweight, low-cost and environmentally friendly option, can also improve its durability and support force after coating with a waterproof layer or adding a reinforcing material to the interlayer, providing diverse choices for the invention to meet the requirements of different needs and environments.

[0052] According to an embodiment of the present invention, the fixed plate is designed as a cuttable structure, and its front part can be cut according to the actual needs of different shoes 1 to adapt to shoes 1 of different sizes, thereby ensuring the versatility and adaptability of the device; its rear part is semicircular, and the shape and size match the bottom shape of the semicircular portion 1602. Through this design, the fixed plate can not only flexibly adapt to various shoe shapes and sizes, but also seamlessly connect with the semicircular portion 1602 of the foot-in device 15 to provide better support and stability.

[0053] According to an embodiment of the present invention, the rear end of the fixed plate portion 151 is embedded in the bottom arc of the semicircular portion 1602 and forms an integral device with the connecting extension portion 1604 by sewing or gluing. This design ensures a firm connection between the fixed plate portion 151 and the semicircular portion 1602, enhances the overall strength and stability of the foot-in device 15, and thus improves the comfort and reliability when wearing shoes.

[0054] According to an embodiment of the present invention, at the bottom of the heel portion 150, the skin material 1500 and the wrapped buffer material 1501 of the heel portion 150 are connected to the shaping shell 1600 as a whole by sewing or gluing. This design ensures a firm combination of all parts, enhances the overall structural strength of the heel portion 150, and thus provides better support and comfort, effectively extending the service life of the device.

[0055] According to an embodiment of the present invention, the foot-in device 15 is inserted above the middle bottom 13 inside the shoe 1, the heel portion 150 is close to the rear shoe upper 111, and the upper end portion 151 protrudes upward in an arc above the rear shoe upper of the shoe 1. Through this design, the user only needs to gently slide the heel from the upper end portion 151 of the heel portion 150 to smoothly put the foot into the shoe without bending down or using hand assistance. This design greatly improves the convenience and comfort of wearing shoes, especially suitable for the elderly, the disabled, and other people who cannot conveniently bend down to wear shoes.

[0056] According to some embodiments of the present invention, the insole portion 12 is placed on top of the fixing plate. In terms of material, it is mainly manufactured by processes such as polyethylene foaming, EVA foaming, and EVA cold pressing to achieve good resilience and a comfortable foot feeling. The insoles made of these materials, especially the foot cup-shaped movable insoles, can effectively wrap and support the feet, providing additional comfort and stability. In daily life, this design allows the insole to be easily taken out for cleaning and maintenance, keeping the inside of the shoe clean and hygienic. By regularly cleaning the insole, odors and stains can be effectively removed, the service life of the shoe 1 can be extended, and the comfort during wearing can be ensured.

[0057] According to some embodiments of the present invention, the sole 14 can be made of a variety of materials according to the needs of the wearing environment conditions, including rubber, TPR (thermoplastic rubber), EVA (ethylene vinyl acetate), PVC (polyvinyl chloride), rubber foam, polyethylene, etc. In recent years, with the rise of the fitness craze, it is recommended to use lightweight sole materials with anti-slip, wear-resistant, and bend-resistant characteristics. Among them, materials such as EVA, secondary MD (double density), and PVC inflation have good anti-slip performance, wear resistance, and lightweight characteristics, and are suitable for the production of sports shoe soles. These materials can not only provide good grip and stability, but also effectively reduce the weight of the shoe 1, improve the wearing comfort, and have good durability, suitable for long-term sports and activities. Therefore, when choosing the sole material, it is recommended to use lightweight materials with anti-slip, wear-resistant, and bend-resistant characteristics according to the wearing environment and usage requirements to ensure the best balance of the performance and comfort of the shoe 1.

[0058] According to an embodiment of the present invention, referring to Figure 8 , the foot entry device 15 is suitable for shoes 1 made by a variety of shoe-making processes, including but not limited to: gluing process, sewing process, molding process, injection molding process, vulcanization process, Goodyear process, overwrap process, etc. These manufacturing processes can be selected according to the characteristics of the materials, the availability of production equipment, and different production requirements, as long as the foot entry device 15 can be effectively fixed inside the shoe 1, the effect of easy wearing and not easy to fall off can be achieved.

[0059] The shoe device of the present invention that facilitates foot entry solves the inconvenience of the traditional shoe-wearing method in a simple-structured and reasonable-designed way, and is particularly suitable for the elderly, the disabled, children who are too late to lift their shoes, and other people who cannot easily bend down to wear shoes. Referring to Figure 8 , by putting this device into various daily shoes 1, the convenience and comfort of wearing shoes can be significantly improved. At the same time, due to the cuttable design of the fixing plate portion 151, this device can adapt to various types and sizes of shoes 1, and has a wide application prospect.
