FIELD

The disclosure relates to a shoe, more particularly to a moisture-permeable waterproof shoe that can be changed to different styles.

BACKGROUND

Referring toFIG. 1, a conventional sock shoe includes an upper1and a sole2fixed to the upper1. In comparison with the traditional shoes (such as leather shoes), this kind of sock shoes can provide better wearability. However, just like the traditional shoes, the appearance of the conventional sock shoe is fixed and cannot be changed. If the user intends to dress up in a different style, he/she can only change to another pair of sock shoes. Further, since the upper1is generally made of a soft simple woven material that does not have stiffness, the upper1cannot support a three-dimensional shape corresponding to the user's foot. Therefore, when the conventional sock shoe is not worn, the upper1usually collapses inwardly and presents a flat wrinkled shape; and when the user wears the conventional sock shoe, it is similar to wearing an ordinary sock in which he/she has to extend his/her fingers inside the flat-shaped upper1and then pull open the upper1so as to insert his/her foot inside the upper1. Thus, the conventional sock shoe cannot be quickly worn, and is inconvenient to use.

SUMMARY

Therefore, an object of the present disclosure is to provide a multi-style moisture-permeable waterproof shoe that is capable of alleviating at least one of the drawbacks of the prior art.

Accordingly, a multi-style moisture-permeable waterproof shoe of this disclosure includes an outer shoe body unit defining an insertion space that has an open top end and a closed bottom end, and a plurality of sock-like inner shoe body units inserted removably and selectively into the insertion space of the outer shoe body unit. Each sock-like inner shoe body unit includes a moisture-permeable waterproof shoe-like inner sleeve, an outer sock body and an inner adhesive layer. The moisture-permeable waterproof shoe-like inner sleeve defines a foot space that has an open top end and a closed bottom end and is made from at least one cut piece. The outer sock body has a sock body portion sleeved on the moisture-permeable waterproof shoe-like inner sleeve. The inner adhesive layer is adhered between an outer surface of the moisture-permeable waterproof shoe-like inner sleeve and an inner surface of the sock body portion.

It should be noted herein that, in other variations of this embodiment, the number of the sock-like inner shoe body units (100a,100b) may be more than two, and the colors of the outer sock bodies20of the sock-like inner shoe body units (100a,100b) may be different.

Referring toFIGS. 8 to 11, in combination withFIGS. 5 to 7, the moisture-permeable waterproof shoe-like inner sleeve10defines a foot space15having an open top end and a closed bottom end, and is made from a cut piece11which includes a lining layer111, an outer fabric layer112, an upright velvet layer113and a moisture-permeable waterproof layer114. The upright velvet layer113has a plurality of spaced-apart pile yarns115woven between the lining layer111and the outer fabric layer112. In this embodiment, the stiffness of the upright velvet layer113is used to support a three-dimensional shape of the moisture-permeable waterproof shoe-like inner sleeve10. The moisture-permeable waterproof layer114is fixed to an outer surface of the outer fabric layer112.

The cut piece11has a main body13, and two wing portions14symmetrically disposed on two opposite sides of the main body13and integrally connected as one piece with the main body13. The main body13has a front convex portion131and a rear concave portion132opposite to the front convex portion131. Each of the front convex portion131and the rear concave portion132has two opposite ends.

Each wing portion14includes a wing lateral edge141spaced apart from the main body13and having a front end and a rear end, a front curved edge142connected between the front end of the wing lateral edge141and a corresponding one of the two opposite ends of the front convex portion131, and a rear mating edge143connected between the rear end of the wing lateral edge141and a corresponding one of the two opposite ends of the rear concave portion132.

In this embodiment, the front curved edges142of the wing portions14are connected by sewing to a periphery of the front convex portion131of the main body13, the wing lateral edges141of the wing portions14are connected by sewing to each other, and the rear mating edges143of the wing portions14are also connected by sewing to each other, thereby forming the shoe-like inner sleeve10. The front curved edge142of each wing portion14has an arc length substantially equal to one half of an arc length of the front convex portion131.

It should be noted herein that, in other variations of this embodiment, the front curved edge142of each wing portion14may be ultrasonically welded to the periphery of the front convex portion131of the main body13, the wing lateral edges141of the wing portions14may be ultrasonically welded to each other, and the rear mating edges143of the wing portions14may be ultrasonically welded to each other.

The waterproof unit12is fixedly connected to the moisture-permeable waterproof layer114(seeFIG. 7) opposite to the outer fabric layer112, and covers the moisture-permeable waterproof layer114at positions corresponding to the junction of the front curved edges142and the periphery of the front convex portion131, the junction of the wing lateral edges141, and the junction of the rear mating edges143.

The waterproof unit12includes a first waterproof strip121and two second waterproof strips122. The first waterproof strip121extends from the front end to the rear end of the shoe-like inner sleeve10, as shown inFIG. 11, and is fixedly connected to and covers the moisture-permeable waterproof layer or outer surface114of the shoe-like inner sleeve10at a position corresponding to the junction of the wing lateral edges141and the junction of the rear mating edges143of the wing portions14.

Each second waterproof strip122is fixedly connected to and covers the outer surface114of the shoe-like inner sleeve10at a position corresponding to the junction of the front curved edge142of each wing portion14and the periphery of the front convex portion131, as shown inFIGS. 7 and 11. The second waterproof strips122interlace with a front end of the first waterproof strip121.

Referring back toFIGS. 5 to 7, the outer sock body20has a sock body portion21sleeved on the shoe-like inner sleeve10, and a cuff portion22that is elastic and that extends upwardly from a top end of the sock body portion21, that is then folded inwardly and downwardly over a top peripheral portion of the shoe-like inner sleeve10toward the foot space15of the shoe-like inner sleeve10. That is, the cuff portion22surrounds the top peripheral portion of the shoe-like inner sleeve10. The cuff portion22is fixed to the lining layer111of the shoe-like inner sleeve10, and defines an entry opening221communicating with the foot space15. In this embodiment, the cuff portion22is sewn to the lining layer111. Further, the sock body portion21is knitted, but is not limited thereto.

The inner adhesive layer30is adhered between an outer surface of the shoe-like inner sleeve10and an inner surface of the sock body portion21, so that the shoe-like inner sleeve10and the sock body portion21tightly abut against each other. In this embodiment, the inner adhesive layer30is a hot melt adhesive, but is not limited thereto.

Referring back toFIGS. 3, 5 and 6, a method of making each sock-like inner shoe body unit (100a,100b) is summarized below, but is not limited thereto. The steps involved in the method of making each sock-like inner shoe body unit (100a,100b) are as follows:

(1) adhering a moisture-permeable waterproof membrane (not shown) on an outer surface of a fabric material (not shown) having a three-layer structure using an adhesive;

(2) cutting the fabric material to obtain the cut piece11(seeFIG. 8);

(3) sewing the cut piece11into a three-dimensional shape to form the shoe-like inner sleeve10(seeFIG. 10);

(4) adhering the first waterproof strip121(seeFIG. 11) and the second waterproof strips122(seeFIG. 11) to the seams of the shoe-like inner sleeve10so as to form the shoe-like inner sleeve10having moisture-permeable and waterproof functions;

(6) spray coating an adhesive layer to the outer surface of the moisture-permeable waterproof shoe-like inner sleeve10;

(7) spray coating an adhesive layer to the inner surface of the sock body portion21of the outer sock body20;

(9) heating the assembly of the outer sock body20and the moisture-permeable waterproof shoe-like inner sleeve10to more than 80° C. for 2 to 10 minutes, so that the outer sock body20and the shoe-like inner sleeve10can be fixedly adhered to each other;

(10) removing the shoe last from the assembly of the outer sock body20and the moisture-permeable waterproof shoe-like inner sleeve10; and

(11) folding the cuff portion22of the outer sock body20inwardly and downwardly over the top peripheral portion of the shoe-like inner sleeve10toward the foot space15of the shoe-like inner sleeve10, and sewing the cuff portion22to the lining layer111of the moisture-permeable waterproof shoe-like inner sleeve10.

Referring back toFIGS. 2 and 3, in use, a user can selectively insert one of the sock-like inner shoe body units (100a,100b) into the insertion space45of the outer shoe body unit200to form a moisture-permeable waterproof shoe300that can match his/her different style of outfit.

From the aforesaid description, the advantages of this disclosure can be summarized as follows:

(1) In comparison with the prior art, the sock-like inner shoe body units (100a,100b) of this disclosure are designed to be inserted removably and selectively into the insertion space45of the outer shoe body unit200so as to form a moisture-permeable waterproof shoe300that can match his/her different style of outfit. Hence, the moisture-permeable waterproof shoe300of this disclosure is flexible to use, so that there is no need for the user to change between different shoes. Further, with each sock-like inner shoe body unit (100a,100b) cooperating with the outer shoe body unit200, the moisture-permeable waterproof shoe300can present a three-dimensional appearance.

(2) In comparison with the prior art, the sock-like inner shoe body units (100a,100b) of this disclosure can use the stiffness of the upright velvet layer113to support the three-dimensional shape thereof, so that when the shoe-like inner sleeve10is inserted into the outer sock body20, the outer sock body20will not collapse, thereby facilitating quick insertion of the user's foot into the foot space15of the shoe-like inner sleeve10. Thus, convenience and comfort in wearing the moisture-permeable waterproof shoe300of this disclosure can be improved.

(3) Since the elastic cuff portion22of the outer sock body20is folded inwardly and downwardly over the top peripheral portion of the shoe-like inner sleeve10toward the foot space15of the shoe-like inner sleeve10and is sewn to the lining layer111of the shoe-like inner sleeve10, the cuff portion22can cover the top peripheral portion of the shoe-like inner sleeve10. By using the cuff portion22, the number of components required for sewing in each of the sock-like inner shoe body units (100a,100b) can be reduced, thereby lowering the manufacturing costs. Moreover, each of the sock-like inner shoe body units (100a,100b) can present an integral appearance, thereby improving the overall appearance of the moisture-permeable waterproof shoe300.

(4) The moisture-permeable waterproof shoe-like inner sleeve10of each sock-like inner shoe body unit (100a,100b) of this disclosure uses the cooperation of the moisture-permeable waterproof layer114with the first waterproof strip121and the second waterproof strips122to effectively prevent penetration of water into an interior of the moisture-permeable waterproof shoe-like inner sleeve10, thereby providing a good waterproof effect to the user's foot. Further, the moisture-permeable waterproof layer114can permit the moisture to discharge outwardly to keep the user's foot dry.

(5) The upright velvet layer113of the moisture-permeable waterproof shoe-like inner sleeve10of each sock-like inner shoe body unit (100a,100b) of this disclosure has good elasticity to facilitate smooth insertion of the user's foot into the shoe-like inner sleeve10. Further, the upright velvet layer113also has good air permeability to effectively enhance the comfort of wearing the moisture-permeable waterproof shoe300. Moreover, the upright velvet layer113is woven between the lining layer111and the outer fabric layer112to form an integral structure, so that the upright velvet layer113cannot be easily separated therefrom.

Referring toFIG. 12, it is worth to mention herein that, in other variations of this embodiment, a height and a structure of the cuff portion22of the sock-like inner shoe body unit (100b′) may be different from a height and a structure of the cuff portion22of the sock-like inner shoe body unit (100a).

Referring toFIGS. 13 and 14, the second embodiment of the moisture-permeable waterproof shoe300of this disclosure is shown to be similar to the first embodiment. However, in this embodiment, the outer sock body20has a bottom surface211, and each of the sock-like inner shoe body units (100a″,100b″) further includes a thin sole80fixedly connected to the bottom surface211of the outer sock body20. The thin sole80has a thickness of 2 to 3 mm, and is made of a material having waterproof and slip-resistance function. In this embodiment, the thin sole80is made of rubber.

Apart from achieving the same effect as that of the first embodiment, the second embodiment can further permit the user to walk around indoor through the sock-like inner shoe body unit (100a″,100b″) after the moisture-permeable waterproof shoe300is removed.

Therefore, the object of this disclosure can indeed be achieved.
