Description

Technical Field

[0001] This utility model relates to the field of shoe technology, and in particular to a shoe and shoe device that are easy to store. Background Technology

[0002] Shoes are becoming increasingly versatile, requiring different types for different occasions. Therefore, shoes need to be lighter and smaller to facilitate storage and portability.

[0003] To minimize space usage, existing shoes are typically arranged as follows: a pair of shoes is placed in a shoebox, with both the left shoe (for the left foot) and the right shoe (for the right foot) arranged vertically, and the heel of the left shoe aligned with the ball of the right shoe, thus saving space. However, this space-saving effect is extremely limited (ideally, the minimum volume occupied equals the volume of the two shoes placed side by side).

[0004] In an attempt to further reduce space occupation, Chinese utility model patent CN219699148U discloses a type of hotel slipper. It features a transverse (width-direction) groove at the top and bottom of the sole, which is bent along the groove and secured with Velcro to maintain the bent state. However, this design has several problems: based on the accompanying drawings (the sole is made of a single solid piece) and technical information available to those skilled in the art, the sole is made of polyurethane or other foamed materials. This results in high resistance during bending (the presence of two grooves further confirms this), and it cannot be bent to the point where the front and back parts of the groove fit together perfectly. Even if forced to this extent, breakage is highly likely. Furthermore, after removing the Velcro, it is difficult to restore the slipper to its initial flat state (where the upper and lower parts of the groove are on the same horizontal plane).

[0005] Therefore, in order to solve the problems of high bending resistance, possible breakage after bending, and poor recovery, this utility model provides a shoe and shoe device that are easy to store. Summary of the Invention

[0006] The first aspect of this utility model provides a shoe that is easy to store, comprising a shoe body, the shoe body including a sole and an upper, wherein:

[0007] The sole forms a flexible area and an anti-flexibility area. The flexible area extends into a narrow region along the width of the sole, and the bending stiffness of the flexible area is greater than that of the anti-flexibility area.

[0008] The bendable area includes a first solid frame and a first hollow area defined by the first solid frame, wherein, by the user's operation, the sole is bent and the hollow area is at least partially compressed to provide space for deformation.

[0009] Furthermore, the bendable area includes bendable grooves disposed along the width direction at the bottom and / or top of the sole.

[0010] Furthermore, the bendable area includes a bendable groove provided at the bottom of the sole along the width direction, while the top of the sole does not have a bendable groove.

[0011] Furthermore, there are two bendable grooves, which are symmetrically arranged on both sides of the center line in the front-back direction. By the user's operation, the bottom of the front and back of the sole or the top of the upper can be folded together to form a folded state.

[0012] Furthermore, after folding in half using the two easily bendable grooves:

[0013] The thickness of the end corresponding to the easily bendable area is T1, and the thickness of the end where the heel and the forefoot of the sole overlap is T2, where T1=T2.

[0014] Furthermore, it also includes a folding fastener, wherein:

[0015] The folding fastener provides the heel portion to press against the forefoot portion, so that the shoe body remains in the folded state.

[0016] Furthermore, there are three or more bendable grooves, which are distributed along the front-to-back direction on the sole of the shoe. By means of an operation, the shoe is bent sequentially along the multiple bendable grooves to form a coiled state.

[0017] Furthermore, it also includes a winding fixation element, wherein:

[0018] The winding fastener provides the heel portion to press against the forefoot portion, so that the shoe body remains in the winding state.

[0019] Furthermore, the bending-resistant region includes a second solid frame and a second hollow region defined by the second solid frame, and the bending stiffness of the easily bent region is greater than the bending stiffness of the bending-resistant region by one or a combination of at least two of the following methods:

[0020] The cross-sectional area of ​​the first solid skeleton is less than the cross-sectional area of ​​the second solid skeleton;

[0021] The first solid skeleton is arranged more sparsely than the second solid skeleton;

[0022] The volume of the first hollow region is greater than the volume of the second hollow region;

[0023] The first hollow region is arranged more densely than the second hollow region.

[0024] Furthermore, the elastic modulus of the material prepared in the easily bendable region is less than the elastic modulus of the material prepared in the resistant-bending region.

[0025] Furthermore, the shoe upper has a single-layer hollow structure; and / or,

[0026] The sole has a multi-layered hollow structure; and / or,

[0027] The sole is integrally formed with or connected to the upper.

[0028] Furthermore, the shoe body is made of an elastomer with a hollow lattice structure, which is integrally formed by 3D printing.

[0029] A second aspect of this utility model provides a shoe device, comprising:

[0030] Any of the above-mentioned shoes; and

[0031] A container for holding the shoe after it has been bent and for keeping it in a bent state.

[0032] The beneficial effects of this utility model embodiment include at least the following:

[0033] 1. Due to the collapse of the hollow area, the first solid skeleton can make slight movements towards the collapsed hollow area, making it easier to bend;

[0034] 2. When bending, the first solid frame can move slightly into the first hollow area to avoid excessive stress on the first solid frame, which would cause it to lose its elasticity and be damaged, thus ensuring its service life. Attached Figure Description

[0050] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0051] In the description of this invention, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0052] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0053] The first aspect of this utility model discloses a shoe that is easy to store, see [link to relevant documentation]. Figure 1 and Figure 6 The shoe includes a shoe body, which comprises a sole 1 and an upper 2. The sole 1 and the upper 2 are combined to define an area for accommodating the foot from the bottom and top (and sometimes the upper 2 also includes a side portion) respectively. When worn, the foot enters this area, the sole 1 supports the foot from the bottom upwards, and the upper 2 covers the foot from the top (including covering with a sheet structure and partial covering with a strip structure). The shoe can include various styles, such as disposable shoes and reusable shoes according to whether they are reusable; hotel shoes, outdoor shoes, etc. according to different spaces of use; slippers and non-slippers according to whether there is an upper 2 at the heel; sports shoes (such as running shoes, basketball shoes, football shoes), casual shoes, etc. according to different functions; and split-toe shoes (such as flip-flops that only separate the big toe, five-toe shoes that separate all five toes, etc.) and non-split-toe types according to whether the toes are separated.

[0054] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The sole 1 forms a bendable area 11 and an anti-bending area 12. The bendable area 11 extends into a narrow region along the width direction of the sole 1 (arrow direction in the figure). In the initial state (when the whole is flat and the user has not applied any bending operation), the bending stiffness of the bendable area 11 is greater than that of the anti-bending area 12. Based on this relationship of bending stiffness, when the user provides a bending moment with the bendable area as the axis, it can be easily bent along the bendable area, thus it can be folded completely or at least partially, thereby reducing the volume occupied and facilitating storage. As the degree of bending gradually increases, if the bending stiffness of the anti-bending area 12 is always greater than that of the current bendable area 11, then the anti-bending area 12 will not bend during the entire bending process; if the bending stiffness of the anti-bending area 12 is less than that of the current bendable area 11, the anti-bending area 12 will begin to deform and will also be bent. Of course, whether the bending resistance zone 12 deforms depends on the relationship between the bending stiffness of the two and the degree of bending (the current bending state).

[0055] See also Figure 4 The bendable area 11 includes a first solid frame 112 and a first hollow area 113 defined by the first solid frame 112. Through user operation, the sole 1 bends to the same side, and the hollow area is at least partially compressed to provide space for deformation. When the sole 1 is bent along the bendable area 11, the hollow area is compressed, providing sufficient space for the first solid frame 112 to deform, thus enabling the sole 1 to bend to a sufficient degree. Because the first solid frame 112 can collapse into the hollow area when deformed, excessive deformation is avoided, ensuring service life.

[0056] It should also be noted that bending can be performed along the easily bendable area 11 towards the same side, such as... Figure 7 The bending direction is towards the top of the sole 1; it can also be done along the bendable area 11 to different sides.

[0057] A bend can be made only once along a single bendable area, resulting in a folded shape. Figure 7 As shown; it can also be bent along multiple easily bendable areas 11, forming a coiled state after bending, as shown. Figure 8 As shown.

[0058] See also Figure 4 One embodiment of the bendable structure 111 may include a bendable groove formed by an inwardly recessed bendable groove, the bendable groove being provided along the width direction, and the bendable groove may be provided on either the bottom or the top of the sole 1, or both simultaneously.

[0059] When a bendable groove is only provided at the bottom of the sole 1, and not at the top, the top of the sole 1 contacts the foot. If a bendable groove is provided at this location, it will affect foot comfort. Furthermore, during walking, both ends (or one end) of the sole 1 may bend upwards, gradually reducing the opening of the bendable groove. This structure could cause the user's foot (when not wearing socks) and / or socks to become trapped, exacerbating the impact on comfort and potentially leading to injury.

[0060] One configuration of the bendable groove is two grooves, which are symmetrically arranged along the center line in the front-to-back direction. Figure 1 On both sides of the dotted line L in the middle, the bottom of the sole 1 (front and back) or the top of the upper 2 (back and back) can be folded together by the user. Folding the sole 1 in half by folding it in half at the front (the part in front of the easily folded area 11) and back (the part in back of the easily folded area 11) is advantageous because the sole 1 is prone to getting dirty when in contact with the ground. Folding this easily soiled part prevents it from contaminating other items in the surrounding environment. After folding, the shoe can be placed in a suitcase and weighed down with other items to prevent it from unraveling, making it easy to store. Alternatively, the tops of the two uppers 2 can be folded together, with the easily soiled sole 1 facing outwards, making it easier to place in environments with relatively poor hygiene, such as on the ground.

[0061] It should also be noted that after folding with the two easily bendable grooves: the thickness of one end corresponding to the easily bendable area 11 is T1, and the thickness of the end where the heel and the ball of the sole 1 overlap is T2, where T1 = T2. This setting makes bending easier; the folded state is of equal thickness, further reducing the volume occupied and making it easier to store.

[0062] To prevent the folded shoe from returning to its flat state due to its own elastic recovery force, the convenient storage shoe embodiment may also include a folding fastener 3, wherein: the folding fastener 3 provides a force that presses the heel against the forefoot, so that the shoe body remains in the folded state. The folding fastener 3 can be a flexible material, such as a rope wound along the width direction, or the rope can be made of an elastic material, such as a rubber band, for further convenience; it can also be a rigid ring, the inner area of ​​which is slightly larger than the folded shoe body, into which the folded shoe body can be directly inserted; or it can be a component that works in two parts, such as a buckle, snap, or Velcro, to lock the shoe, with one part located at the heel and the other at the forefoot.

[0063] When bending by a winding method, there are three or more bendable grooves, which are distributed (at substantially equal intervals) along the front-back direction on the sole 1. The shoe is then bent sequentially along the multiple bendable grooves by an operation to form a winding state.

[0064] To maintain the rolled-up state, the conveniently stored shoe may also include a rolling fastener 4, which provides pressure between the heel and the foot. The rolling fastener 4 can be a flexible material, such as a rope that is wound longitudinally (front to back). The rope can also be made of an elastic material, such as a rubber band, for further ease of use. Alternatively, it can be a rigid ring, the inner area of ​​which is slightly larger than the rolled-up shoe body, into which the rolled-up shoe body can be directly inserted. It can also be a two-part locking component, such as a buckle, snap, or Velcro, with one part located at the heel and the other at the foot.

[0065] It should also be noted that the bending-resistant region 12 includes a second solid frame 121 and a second hollow region 122 defined by the second solid frame 121. The bending stiffness of the easily bent region 11 is greater than that of the bending-resistant region 12 by one or a combination of at least two of the following methods:

[0066] The cross-sectional area of ​​the first solid skeleton 112 is less than the cross-sectional area of ​​the second solid skeleton 121;

[0067] The first solid skeleton 112 is arranged more sparsely than the second solid skeleton 121;

[0068] The volume of the first hollow region 113 is greater than the volume of the second hollow region 122;

[0069] The first hollow region 113 is arranged more densely than the second hollow region 122.

[0070] The bending stiffness of the easily bent region 11 being greater than that of the bending-resistant region 12 can also be achieved by the following method: the elastic modulus of the material used to prepare the easily bent region 11 being less than the elastic modulus of the material used to prepare the bending-resistant region 12.

[0071] To facilitate bending, the upper 2 has a single-layer hollow structure, which is thinner and has less bending stiffness, making it easier to bend while reducing the volume after bending.

[0072] The sole has a multi-layered hollow structure to ensure sufficient elasticity and deformation range for comfortable wear.

[0073] The sole 1 and the upper 2 are integrally formed or connected and fixed.

[0074] It should also be noted that the shoe body is made of an elastomer with a hollow lattice structure, which is 3D printed in one piece. For one type of structure of the hollow lattice elastomer, see [link to previous section]. Figures 1 to 6Of course, the elastomer can also utilize 3D-printed shock-absorbing components disclosed in CN218971713U, rebound elements disclosed in CN219182950U, cushioning and shock-absorbing components disclosed in CN212414939U, and pressure-resistant and breathable cushioning components disclosed in CN212737077U. The lattice-like hollow structure created using 3D printing technology not only boasts a futuristic appearance but also achieves extreme lightweighting; a size 41 weighs only 90-100 grams, and is soft and elastic. The sole is designed for flexibility, folding for easy carrying and storage. Simultaneously, the shoe's quiet characteristics significantly reduce noise during walking, providing a quiet and comfortable experience both indoors and outdoors. This shoe combines the barefoot concept, loose comfort, toe-fitting design, and modern technology, offering users a lightweight, natural, and convenient new wearing experience.

[0075] The second aspect of this utility model discloses a shoe device, see [link to relevant documentation]. Figure 7 and Figure 8 It includes:

[0076] Any of the above-mentioned shoes; and

[0077] Container 5 is used to hold the bent shoe and keep it in a bent state. Container 5 can be a flexible bag or a box with a certain degree of rigidity, such as... Figure 7 As shown, the box includes an open box body 51 and a lid 52. When using it, assemble it according to the sequence of the dotted lines in the diagram. The folded shoe body is secured with the folding fastener 3 and then placed into the box body 51, finally covered with the lid 52. Of course, by designing the internal space of the box body 51, it can accommodate only one folded shoe, one pair, or multiple pairs.

[0078] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
