Description

Technical Field

[0001] The utility model belongs to the technical field of shoe covers, and particularly relates to a stepped self-locking hospitality shoe cover. Background Art

[0002] When there are guests at home, considering aspects such as health, courtesy, and convenience, using shoe covers is often more popular than changing into slippers. Currently, shoe cover products on the market can be roughly divided into three categories:

[0003] The first category is disposable plastic shoe covers, which are put on the shoes by hand when entering the door and taken off and thrown away by hand when going out. When wearing such products, users need to stand, bend down, and lift their feet, which is not aesthetically pleasing and appears cumbersome. At the same time, the feet feel stuffy, and the shoe covers need to be cleaned up after use, causing inconvenience to users and wasting resources.

[0004] The second category is convenient shoe cover devices. Such products place disposable plastic shoe covers in advance through a simple device. After the user steps into the shoe cover area of the device, the device releases the buckle that fixes the shoe cover after the shoe cover area is stepped on, so that the elastic band at the opening of the shoe cover automatically contracts and then fits over the shoe. Such products only solve the difficulty caused by the action of the user standing, bending down, and lifting their feet to put on the shoes, but also increase the workload of placing shoe covers in the device. Moreover, during the stepping process, multiple shoe covers may be released or some buckles may not be loosened, resulting in the situation that the shoe covers cannot be put on the shoes at one time, and there are relatively large defects.

[0005] The third category is sole laminating machines. Such products are that after the user steps the sole into the laminating area, the plastic film adheres to the sole, then the foot is lifted out, and then the plastic film is stretched and torn on the serrated metal setting at the edge of the laminating machine, so as to complete the isolation of the sole from the floor and play a certain protective role. However, such products are not very aesthetically pleasing, there are situations where it is not easy to adhere the plastic film due to dirty soles of users, and the plastic film may fall off during walking. At the same time, such products have serrated metal settings exposed outside. If there are children crawling on the ground in the family, it may hurt the children.

[0006] Finally, the two types of products, convenient shoe cover devices and sole laminating machines, also have defects in high cost, relatively complex structure, taking up space, and requiring maintenance; disposable plastic shoe covers also have the disadvantages of not being enough if bought less and taking up the shoe cabinet if bought more. Content of the Utility Model

[0007] The purpose of the utility model is to provide a stepped self-locking hospitality shoe cover to solve the problems and defects of the prior art mentioned in the above technical background.

[0008] To achieve the above purpose, the utility model provides the following technical solutions:

[0009] A stepped self-locking hospitality shoe cover, comprising a flexible wrapping layer. On the inner and outer sides of the tip of the flexible wrapping layer, two protrusions are respectively arranged. Inside the inner protrusion, a shape memory metal plate I is embedded, and inside the outer protrusion, a shape memory metal plate II is embedded. Inside the heel part of the flexible wrapping layer, a shape memory metal plate III is embedded. Under the stress-holding state, the shape memory metal plate I and the shape memory metal plate II are straight along the length direction, and the left and right sides are bent downward into an arch shape. The shape memory metal plate III is in an arch shape with the left and right sides bent downward. The original memory shapes of the shape memory metal plate I and the shape memory metal plate II are in a curled shape that bends upward along the length direction. The original memory shape of the shape memory metal plate III is that the front section is straight on the left and right sides, the rear section is slightly curled upward on the left and right sides, and the rear section curls upward along the length direction.

[0010] This technical solution cleverly applies the shape memory of shape memory metal at room temperature and normal temperature, and its physical property of being able to restore to the original memory shape after stress damage. The integrated structural design makes the appearance of the shoe cover more beautiful and concise, and it is convenient to use and store without occupying space.

[0011] Further, the original memory shape of the 2 cm - 3 cm section at the front of the shape memory metal plate III is straight.

[0012] The 2 cm - 3 cm section at the front of the shape memory metal plate III is stepped on the sole of the foot, making the sole of the foot more flat and comfortable after the shoe cover is worn.

[0013] Further, the shape memory metal plate I and the shape memory metal plate II are the same in size and shape, and arcs are arranged at the front ends of the shape memory metal plate I and the shape memory metal plate II. The left and right sides of the rear section of the shape memory metal plate III protrude in a T-shaped structure, and the corners are all rounded.

[0014] The front ends of the shape memory metal plate I and the shape memory metal plate II are designed in an arc shape to prevent the metal plate from scratching the flexible wrapping layer. The shape memory metal plate III adopts a T-shaped structure, which can make the shoe cover fit more tightly on the heel of the shoe. The purpose of rounding the corners is to prevent the flexible wrapping layer from pricking the shoe or the skin when it is damaged.

[0015] Further, the center line of the shape memory metal plate I forms an angle of 65° - 75° with the center line of the flexible wrapping layer, and the center line of the shape memory metal plate II forms an angle of 40° - 50° with the center line of the flexible wrapping layer.

[0016] The shape memory metal plate I, the shape memory metal plate II and the center line of the flexible wrapping layer are set at different angles, which is designed according to ergonomics, making the shoe cover similar to the shape of the human foot sole, enabling the shoe cover to fit more tightly on the shoe and being more comfortable to wear.

[0017] Further, granular protrusions are provided on the upper surface of the flexible wrapping layer at the front ends of the shape memory metal plate I and the shape memory metal plate II, and at the left and right protruding parts at the rear end of the shape memory metal plate III.

[0018] After the shape memory metal plates are deformed and restored to the memory shape, the front ends of the shape memory metal plate I and the metal plate II, and the left and right protruding parts at the rear end of the shape memory metal plate III will wrap around the shoe upper. The granular protrusions provided on the surface of the flexible material wrapping layer can effectively increase the friction between the flexible wrapping layer and the shoe upper, ensuring that the shoe cover is fixed on the shoe and not easily fallen off.

[0019] Further, the thickness of the middle section of the flexible wrapping layer is greater than that of the tip or the heel part.

[0020] Because the shape memory metal plates at the tip and the rear root of the flexible wrapping layer increase the weight of the shoe cover, appropriately thickening the flexible material at the middle instep part can not only balance the overall quality of the shoe cover, but also increase the "step on shit" feeling, bringing a more comfortable wearing experience.

[0021] Further, the flexible wrapping layer is made of a flexible material.

[0022] Latex or rubber materials have better plasticity and wrapping properties compared with cloth materials. At the same time, they are more beautiful and easy to care for, and can wrap more closely around the shoe surface.

[0023] The beneficial effects of the present utility model compared with the prior art:

[0024] The present utility model ingeniously applies the physical property that the shape memory metal can be restored to the memory shape at normal temperature. The guest only needs to gently step on the shoe cover, and the shape memory metal will release stress and return to the memory shape at normal temperature. The shape memory metal drives the flexible wrapping layer wrapped outside to buckle on the shoe surface, and is well fixed to the shoe. This shoe cover does not stuff the feet, can be reused, has a simple design, low cost, a simple appearance, is convenient to put on and take off, has no potential danger, is not easy to fall off, and the design of thickening the shoe sole part makes it have a slightly "step on shit" feeling after wearing, further improving the user experience.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] As Figures 1-4 shown, Figure 1 is a top view structural schematic diagram of a step-on self-locking shoe cover according to an embodiment of the present invention; Figure 2 is a left view structural schematic diagram of a step-on self-locking shoe cover according to an embodiment of the present invention;

[0033] Figure 3 is a right view structural schematic diagram of a step-on self-locking shoe cover according to an embodiment of the present invention; Figure 4 is a front view structural schematic diagram of a step-on self-locking shoe cover according to an embodiment of the present invention; The following preferred technical solutions are provided:

[0034] A step-on self-locking hospitality shoe cover includes a flexible wrapping layer 1. Two protrusions 2 are respectively arranged on the inner and outer sides of the tip of the flexible wrapping layer 1. A shape memory metal plate I 3 is embedded inside the inner protrusion 2, and a shape memory metal plate II 4 is embedded inside the outer protrusion 2. A shape memory metal plate III 5 is embedded inside the heel part of the flexible wrapping layer 1; before the shoe cover is worn, the shape memory metal plate I 3, the shape memory metal plate II 4, and the shape memory metal plate III 5 are in a stress-retaining state. The shape memory metal plate I 3 and the shape memory metal plate II 4 are in an arched shape with both front and rear ends bent downward, and the shape memory metal plate III 5 is in an arched shape with both left and right sides bent downward. The original memory shape of the shape memory metal plate I 3 and the shape memory metal plate II 4 is a curled shape bent upward along the length direction, and the original memory shape of the shape memory metal plate III 5 is an arched shape with both left and right sides bent downward in the front section and a curled shape with both left and right sides and the rear end bent upward in the rear section; when the shape memory metal plate is subjected to force, the stress is immediately released and it returns to its original memory shape.

[0035] In this embodiment, the flexible wrapping layer 1 and the shape memory metal plate are of an integral structure. The shape memory metal plate is embedded inside the flexible wrapping layer 1. During production, the shape memory metal plate is placed in a specific mold according to specific dimensions and angles, and then melted latex or rubber is poured into the specific mold. After cooling, the integral shoe cover flexible wrapping layer 1 is formed.

[0036] In this embodiment, the original memory shapes of the first 2 cm - 3 cm section of the front part of the metal plate III 5 are all straight. The deformation process of the shape memory metal plate III 5 is as follows: when the foot steps on it, the whole shows an arched structure with both left and right sides bent downward. After the foot steps on it, the first 2 cm - 3 cm section of the front part becomes straight, and the rear part shows a slightly upward curl on both left and right sides, and the rear part curls upward along the length direction.

[0037] Among them, the shape memory metal plate I 3 and the shape memory metal plate II 4 are of the same size and shape, and arcs are provided at the front ends of both the shape memory metal plate I 3 and the shape memory metal plate II 4. The left and right sides of the rear part of the shape memory metal plate III 5 protrude to form a T-shaped structure, and the corners are all set as rounded corners.

[0038] Among them, the center line 6 of the shape memory metal plate I forms an angle of about 70° with the center line 8 of the flexible wrapping layer, and the center line 7 of the shape memory metal plate II forms an angle of about 45° with the center line 8 of the flexible wrapping layer.

[0039] Among them, granular protrusions 9 are provided on the upper surface of the flexible wrapping layer 1 at the front ends of the shape memory metal plate I 3 and the shape memory metal plate II 4, and at the left and right protruding parts at the rear end of the shape memory metal plate III 5.

[0040] Among them, the thickness of the middle section of the flexible wrapping layer 1 is greater than the thickness of the tip or the heel part.

[0041] In this embodiment, the flexible wrapping layer 1 is made of flexible materials such as latex, rubber, silica gel, etc., and the shape memory metal plate is made of nickel-titanium alloy material or other materials with the same characteristics.

[0042] Wearing method of the shoe cover: Before entering the door, the visitor steps on the shoe cover. Under the action of pressure, the shape memory metal plate releases stress and automatically returns to its memory shape, and the shape memory metal plate drives the flexible wrapping layer 1 to fit and buckle on the shoes.

[0043] Removing method of the shoe cover: Use the hand to flatten the shape memory metal plate III 5 behind the heel to form an arch and then take out the foot, or use the tip of the other foot to step on and flatten the shape memory metal plate III 5 behind the heel and then take out the foot. The shape memory metal plates I 3 and II 4 at the front end do not need to be flattened and will maintain a state of maximum curl to a certain extent. This state does not affect the next time the shoe tip part is put in, and at the same time, it can still buckle on the shoe. Next time when wearing, just put the shoe tip into the tip of the shoe cover and gently step on the shape memory metal plate III 5 at the rear root of the shoe cover.

[0044] Shoe cover size description: This shoe cover is made in pairs. Only the right shoe cover is shown in this embodiment, and the left one is symmetrical to it. At the same time, since different guests may visit wearing shoes of different sizes, considering that the size gap between size 36 and size 43 shoes is relatively large, the shoe cover can be designed in two sizes, namely a small version suitable for shoes of size 36 - 40 and a large version suitable for shoes of size 40 - 43. Additionally, it should be noted that the scale of the drawings in the specification deviates from the actual object and is only for understanding the product structure.

[0045] The above is only the best embodiment of the present utility model and is not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
