Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sandals, in particular to a leisure sandal structure. Background Art
[0002] Sandals are a kind of open footwear. The biggest feature of sandals is their open design, which helps to ventilate the feet and reduce the generation of sweat and odor. Sandals come in various styles, such as casual sandals. They have the shape of casual shoes and are suitable for wearing in various casual occasions. At the same time, openings of different sizes are arranged on both sides of the arch of the human foot, the instep of the human foot and the toes of the human body to ensure ventilation and air permeability. Sandals include uppers, tongues, toes and soles. In order to improve the durability of sandals, the soles are now divided into comfortable insoles suitable for foot contact and outsoles with good wear resistance. Existing sandals basically use glue to bond the soles and uppers, including the two layers of the soles. Sandals bonded with industrial glue are prone to environmental pollution, and people cannot disassemble them to replace the insoles by themselves later. Utility Model Content

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] As shown in the accompanying drawings, the utility model discloses a casual sandal structure, comprising an upper 1 and a sole 2, wherein the upper 1 comprises two symmetrically arranged waist surfaces, a toe surface and a heel, which are not marked in the figure and can be referred to the existing structure, and a tongue 3 connected to the toe surface by a buckle is arranged between the two waist surfaces; the upper 1 as a whole and the tongue 3 are made of a colloid material, such as rubber, etc., and the sole 2 comprises an inner layer 21 and an outer layer 22, the inner layer 21 can be made of soft plastic to improve its comfort, and the outer layer 22 can be made of hard plastic to increase its wear resistance, the outer layer 22 and the upper 1 are an integrally formed structure, and a groove 220 matching the inner layer 21 is recessed in the middle of the outer layer 22, and the cross-sectional shape and size of the groove 220 correspond to the shape and size of the inner layer 21, and the inner layer 2 1 is provided with a high part corresponding to the heel and a low part corresponding to the forefoot. This design is also to meet the ergonomic design, make people wear more comfortable, evenly force, enhance stability, etc., and the groove 220 is also set with a corresponding depth at its corresponding position according to the high part and the low part of the inner layer 21. The groove wall of the groove 220 has the same thickness as the corresponding position of the inner layer 21. The groove wall of the groove 220 is provided with a drainage port 222. The inner layer 21 is arranged in the groove 220, and a positioning block 211 corresponding to the drainage port 222 is arranged on the outer side of the inner layer 21. It should be noted that the drainage port 222 has a drainage function, which can discharge the surface water of the inner layer 21, and can cooperate with the positioning block 211 to fix the inner layer 21. The positioning block 211 is arranged on the outer side of the inner layer 21 and is close to the upper surface.
[0017] The utility model discloses a leisure sandal structure, which has a toe surface connected to a shoe by a shoe tongue 3 buckle, a shoe upper 1 and an outer layer 22 integrally formed, and at the same time, the outer layer 22 and the inner layer 21 are also connected by a clamping structure, replacing the glue bonding structure, so as to achieve a glue-free connection and reduce pollution, and the inner layer 21 and the outer layer 22 are detachable, the inner layer 21 is placed in a groove 220, and is clamped and fixed with a drainage port 222 of the outer layer 22 by a positioning block 211, so that people can replace the inner layer 21 by themselves.
[0018] In this embodiment, a clamping block 31 is provided at one end of the shoe tongue 3, and a clamping slot 100 is provided on the toe surface and is buckled and connected to the clamping block 31, and the assembly of the shoe tongue 3 is achieved by connecting the clamping block 31 and the clamping slot 100.
[0019] like Figure 2-3As shown, there are four drain outlets 222 and positioning blocks 211, two of which are arranged on both sides of the corresponding forefoot, and the other two are arranged on both sides of the corresponding heel. The four drain outlets 222 are symmetrically arranged on both sides of the outer layer 22, and the four positioning blocks 211 are symmetrically arranged on both sides of the inner layer 21. The position is designed according to ergonomics. The forefoot and the heel are the main pressure points. The four drain outlets 222 are arranged near the corresponding pressure points, which is conducive to drainage. When people wear it, the forefoot or the heel will press the inner layer 21, and the corresponding position area of the inner layer 21 will be compressed and depressed, which is easy to accumulate water, and the accumulated water will be discharged through the drain outlet 222 corresponding to the area; the height of the drain outlet 222 is ≥ the height of the positioning block 211; the drain outlet 222 gradually increases from the inside to the outside, and the cross-section of the drain outlet 222 is trumpet-shaped, which is conducive to the discharge of accumulated water.
[0020] In this embodiment, shoelace holes are arranged on one side of the shoe waist surface, and a channel 300 for threading shoelaces is arranged on the front of the shoe tongue 3. Shoelaces are also included. Referring to existing casual shoes, the shoelace holes are used to connect the two shoe waist surfaces to achieve the effect of adjusting tightness. When threading the shoelace holes, the shoelaces pass through the channel 300 to assist in positioning the shoe tongue 3. The shoelaces can also be adjusted using a shoelace buckle.
[0021] The above embodiments are preferred embodiments of the present utility model. All structures similar to the present utility model and equivalent changes made thereto should fall within the protection scope of the present utility model.
