Description

One-piece sole with air layer inside

The utility model relates to a shoe sole, in particular to a shoe sole with an inner air layer.

Please refer to Fig. 1, this is a common shoe sole 10 formed by plastic injection molding, on which the ribs 11 are arranged in a grid and staggered to form a predetermined number of diamond-shaped spaces 12, and the weight of the shoe is reduced by the hollow spaces 12. And maintain the structural strength of the sole 10 with the ribs 11 connected; however, the weight of the sole 10 formed with this type of structure can be reduced and the structural strength is sufficient, but it causes the disadvantage of poor shock absorption of the sole. The space formed by the ribs is too strong to deform properly.

In order to make the bottom of the shoe have better shock absorption, light weight and structural strength, etc., in the footwear industry, there has been developed a foam-molded shoe midsole made of EVA, PU, etc., and then cooperate with the sole to form the bottom of the shoe. The characteristics of PU and other materials can achieve shock-absorbing, light weight and good structural strength of the bottom of the shoe; however, the sole made of this type still has high material manufacturing costs (because PU, EVA and other materials are more expensive than ordinary plastics), shock-absorbing The strength is still insufficient, the weight is heavy (because the midsole is usually solid) and other shortcomings.

On the other hand, recently, air bags or oil bags are also arranged at the bottom of the shoes, so as to achieve the effect of air cushion shoes with good elasticity and shock absorption; Therefore, the processing operation is relatively complicated, and the shock-absorbing effect achieved by it is only partial, and the shock-absorbing effect is limited because the setting of the air bag is tied to the part of the sole.

The purpose of the utility model is to provide a shoe sole with an air layer inside, which can increase the shock-absorbing force of the shoe sole, reduce the weight of the shoe sole and reduce the manufacturing cost.

The technical scheme of the utility model is:

An integrally formed sole with an air layer, characterized in that it includes:

A base, which is made of plastic, with an outer edge and a wall edge protruding from the peripheral edge of the base; a setting groove is formed between the outer edge and the wall edge;

A covering layer, the edge of which protrudes to form a covering edge, and the covering edge is embedded in the installation groove, so that the covering layer covers the base layer, and a space for containing air is formed between the covering layer and the base layer space;

A bonding layer covers the covering layer, and its edge extends into the setting groove to combine with the surrounding side of the covering layer and the base layer as a whole.

The integrally molded sole with an air layer is characterized in that a plurality of supporting blocks are protrudingly formed on the side of the base layer facing the covering layer.

The utility model has the advantages of:

The integrally formed sole with an air layer of the utility model is formed with a setting groove on the periphery of the base layer, and is placed on the cover layer with a protruding cover edge, and then covered and bonded to the cover with a bonding layer. The combined layer and the base layer form a space between the base layer and the cover layer that can accommodate air, thereby increasing the shock-absorbing force of the sole, reducing the weight of the sole and reducing the manufacturing cost.

The utility model will give a preferred feasible embodiment and describe it in detail in conjunction with the drawings as follows.

The descriptions of the accompanying drawings are as follows:

First, please refer to Figures 2, 3, and 4. The utility model provides a shoe sole with an air layer in one piece, which is mainly composed of a base layer 20, a covering layer 30 and a bonding layer 40; wherein:

The base layer 20 is integrally formed by plastic injection, and a closed annular outer edge 21 and a wall edge 22 protrude from the peripheral edge of the base layer 20; a setting groove 23 is formed between the outer edge 21 and the wall edge 22 A first space 24 is formed inside the edge of the wall 22; a predetermined number and type of support blocks 25 are protruded from the surface of the base layer 20 located in the first space 24;

The cover layer 30 has a cover edge 31 corresponding to the setting groove 23 protrudingly formed on its peripheral side, and a second space 32 is formed inside the cover edge 31; the cover layer 30 is embedded with its cover edge 31. Set in the setting groove 23, so that the cover layer 30 is covered with the base layer 20, and the first space 24 of the base layer 20 is connected with the second space 32 of the cover layer 30 to form an air chamber 50; After 31 is embedded in the setting groove 23, there is still a gap 33 on the setting groove 23, (as shown in Figure 3);

The bonding layer 40 is injection-molded to cover the outer surface of the covering layer 30, and is tightly combined with the surrounding sides of the covering layer 30 and the base layer 20 through the gap 33 where its edge extends into the setting groove 23.

The above is the narration of the structure and positional relationship of each layer formed by the present utility model, wherein, the bonding layer 40 is the last to be arranged, so it can be covered on the outer surface of the covering layer 30, and the gap 33 at the groove 23 is closely spaced. The base layer 20 and the cover layer 30 (as shown in FIG. 4 ) form an airtight air-holding chamber 50 on the sole. 24 and the second space 32.

Please refer to Fig. 4 and shown in Fig. 5, the area covered by the air chamber 50 of the shoe sole formed by the structure of the present utility model is almost the whole of the shoe sole. Therefore, not only the overall weight of the shoe sole can be greatly reduced, but also the achieved The shock-absorbing area is relatively uniform and the shock-absorbing effect is excellent; on the other hand, the plastic injection molded shoe bottom (the part directly in contact with the ground) is a necessary structure for general shoe manufacturing; The creative structure can use lower-priced plastics to directly inject each layer of the sole, without the need to separately manufacture or install shock-absorbing structures such as PU, EVA, or airbags, which are commonly used, and will definitely save and reduce manufacturing costs.

On the other hand, in the present invention, a support block 25 protrudes from the surface of the first space 24 of the base layer 20, which can not only increase the supporting strength of the air chamber 50, but also prevent the air chamber 50 from being punctured by a foreign object. , still be able to keep the available sole state (as shown in Figure 2).

Please refer to Fig. 6, which is a schematic cross-sectional view of the structure of the utility model implemented in the sole of a high-heeled shoe, that is, at the heel of the high-heeled shoe (because the heel is usually the place where the high-heeled shoe is stressed), the base layer 20 is formed The bottom of the shoe, and on the base layer 20, a groove 23, a support block 25 and a first space 24 (same as shown in Figure 3) etc. are formed, so that the cover layer 30 is set to cover it, and the cover edge 31 is located in the groove 23, and finally cover the covering layer 30 and the base layer 20 with the bonding layer 40 to form a heel with an air chamber 50 inside.
