Description
i i i i InIATERPROOF SHOE HAVING STITCH SEAM FOR DRAINAGE IT
BACItGROUND OF THE INVENTION
1. Field of the Invention The invention relates to a waterproof shoe, more particularly to a waterproof shoe with an inner liner which is made of a water impervious but vapor-permeable material disposed inside an upper and which has a bottom open end stitched to the upper to form a draining seam above the bottom end of the upper.
BACItGROUND OF THE INVENTION
1. Field of the Invention The invention relates to a waterproof shoe, more particularly to a waterproof shoe with an inner liner which is made of a water impervious but vapor-permeable material disposed inside an upper and which has a bottom open end stitched to the upper to form a draining seam above the bottom end of the upper.
2. Description of the Related Art Conventional waterproof shoes generally include an outer shell made of a waterproofing material which is impervious to air and vapor. Such waterproof shoes tend to cause discomfort to the wearer as ventilation of perspiration vapors gathered around the wearer's feet is not permitted.
Improvements available in the art for coping with such perspiration problems include the use of a non-waterproof material, such as leather or fabric, for the outer shell of an upper and the use of a sock-like liner, which is made of a material or laminate impervious to water but pervious to perspiration vapor, as a protection part for the foot against water intrusion. In particular, shoe constructions with such an improvement generally include a sock-like liner which has a top open end secured to the top open end of an upper, and a bottom wall seating on and bonded adhesively to a midsole which is secured to the bottom end of the upper.
i i A disadvantage found in such constructions is that water can seep into the interior of the shoe through the seams of the shoe and can be trapped in the space between the upper and the sock-like liner.
Attempts have been made in order to alleviate the aforesaid water seeping problems by improving the waterproofing characteristics of the waterproof breathable shoes . U. S . Patent No . 5 , 678 , 326 suggests an improved shoe construction which comprises an outer shell connected to an insole, a waterproof, water-vapor permeable shoe insert disposed inside the outer shell, and a lining provided inside the shoe insert . Both of the lining and the shoe insert have their bottom walls extending between an outsole and an insole, and are secured to the bottom portion of the upper and to the outsole and insole by using several layers of adhesive.
As described hereinabove, the prior art addressed the aforesaid water seeping problem by focusing on improvements on the waterproofing characteristics of the shoes. The technical measures taken in the art to enhance the waterproofing characteristics, however, tend to reduce the ventilating characteristicsand vapor permeability of shoes.

i.
U.S. Patent No. 4,599,810 discloses stitchdown shoes which incorporate waterproof, vapor permeable sock-like liners and which provide good ventilating property. In the construction of these shoes, although a stitchdown formed at the joint of a midsole and an upper permits ventilation, since a padding, which is typically made of a fibrous or foamed material, is disposed between the inner surface of the upper and the sock-like liner, the water penetrating through the stitchdown can be retained in the padding due to the water-wicking property of the padding. The wet padding not only adds weight to the shoe but also reduces the warmness of the shoe . On the other hand, the sock-like liner used in this shoe construction has a bottom wall which seats on a midsole and is secured adhesively thereto. The need to provide the liner with the bottom wall complicates the process of making the shoe and increases the consumption of expensive waterproof, vapor permeable material. The procedure for securing adhesively the bottom wall of the liner to the midsole is also cumbersome and time-consuming.
SUI~'ARY OF THE INVENTION
An object of the present invention is to provide a waterproof shoe which permits the wearer's feet to breathe and which has a drain outlet for the water invading the interior of the shoe.
Another object of the present invention is to provide a waterproof breathable shoe which can be produced via a less complicated process with reduced consumption of expensive waterproof breathable material.
According to the present invention, a waterproof shoe comprises: an upper including a top open end and a bottom open;end; and a lining sleeve disposed inside the upper, the lining sleeve having a top open end connected to the top open end of the upper, and a bottom open end extending along an inner surface of the upper and ending at a distance from and above the bottom open end of the upper. The bottom open end of the lining sleeve is stitched to the upper to form a seam, and the lining sleeve is made of a material which is impervious to water but is pervious to perspiration vapors .
Waterproof means is attached to the inner surface of the upper and the inner surface of the lining sleeve adjacent to and along the seam so that the water invading the shoe can be diverted to drain out of the shoe through the seam.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to Figures l, 2A, 2B and 2C, a preferred embodiment of the waterproof shoe according to the present invention is shown to include an upper 1 having a toe cap 13 and a counter 14. The toe cap 13 and the counter 14 are stitched to a quarter section 15 of the upper 1 so that a seam 30a is formed between the toe cap 13 and the quarter section 15 and a seam 30b is formed between the counter 14 and the quarter section 15. The toe cap 13 and counter 14 are preferably made of a waterproof material, such as rubber, PVC, PU or a waterproof leather. The upper 1 has a bottom open end lasted to form an inwardly turned bottom flange 12 .
A lining sleeve 2 is disposed inside the upper 1 and has a top open end (not shown) secured to the top open end 11 of the upper 1 in a conventional manner. The lining sleeve 2 is made of a typical material which is impervious to water but pervious to perspiration vapors, and may consist of a shaped single piece, or a plurality of pieces which are connected together via a stitching process followed by a watertight sealing process in a conventional manner. The lining sleeve 2 has a configuration substantially conforming to the interior of the upper 1 but has a bottom open end 21 which ends at a distance from and above the bottom flange 12 of the upper 1 and which extends along and is connected to the seams 30a and 30b. As shown in Figure 2B, a portion of the bottom open end 21 of the lining sleeve 2 extends to the marginal end of the quarter section 15 which overlaps the toe cap 13, and is connected to the quarter section 15 and the toe cap 13 along the seam 30a. As shown in Figure 2C, another portion of the bottom open end 21 of the lining sleeve 2 extends to the other marginal end of the quarter section 15 which overlaps the counter 14, and is connected to the quarter section 15 and the counter 14 along the seam 30b. As shown in Figure 2A, the remaining portions of the bottom open end 21 of the lining sleeve 2 are stitched to the quarter section 15 along seams 3 at the medial and lateral sides of the upper 1. The quarter section 15 has no jointed overlapping parts at the seams 3 . Note that the bottom open end 21 of the lining sleeve 2 does not extend below the intersection of the seams 3 and 30a and the intersection of the seams 3 and 30b.
A waterproof tape 31 is adhesively bonded to the inner surface of the upper 1 and the inner surface of the lining sleeve 2 adj acent to and along the inner side of the stitched seams 3, 30a and 30b. The bottom end of the waterproof tape 31 extends to the bottom flange 12 of the upper 1. The waterproof tape 31 serves to prevent the water invading through the stitched seams 3, 30a and 30b from entering the interior of the lower part of the upper 1 and divert drainage of the invading water to the outside of the shoe through the stitched seams 3, 30a and 30b. The waterproof tape 31 also provides enhanced waterproofness at the bottom end of the upper 1.
The bottom flange 12 of the upper 1 and the bottom end of the waterproof tape 31 are secured to an insole and an outsole 5 by means of a watertight soling process, such as injecting or applying an adhesive, etc. A filler 7 is inserted into an opening confined by the bottom flange 12 of the upper 1 and by the bottom end of the waterproof tape 31 between the insole and outsole 4 and 5. A waterproof cover 8 is provided beneath the f filler 7 . A conventional inner liner 6 which has a shape substantially conforming to that of the inner surface of the upper 1 is disposed inside the lining sleeve 2 in a conventional manner in order to provide comfort and durability. If desired, a foot-like padding (not shown) may be disposed on a bottom wall of the inner liner 6 in a conventional manner.
Although the waterproof tape 31 shown in Figure 2 extends to the bottom flange 12 of the upper 1, the present invention is not limited thereto. As shown in Figure 3, a waterproof tape 31' is formed as a strip that does not extend to the bottom flange 12 of the upper but extends along the stitched seams 3, 30a and 30b. In this case, the quarter section 15 should be made of a waterproof material so as to ensure that the lower part of the quarter section 15 below the strip is waterproof. In place of the waterproof tape 31, 31' a waterproof coating may be applied to the inner surfaces of the upper 1 and the lining sleeve 2 in a conventional manner.
Figure 4 and 5 show other embodiments of the present invention which are substantially similar to those shown in Figures 2 and 3 except that the lining sleeve 2 has a folded bottom end 22 which is turned upward and outward and which is stitched to the upper 1. The folded bottom end 22 can provide an enhanced waterproofing effect as it effectively prevents downward flowing of the invading water.
Figure 6 shows another embodiment of the present invention which is substantially similar to that shown in Figures 1-2C except that the bottom end of the waterproof tape 31" has a dimension greater than that of the bottom flange 12 of the upper 1. The construction as such permits saving of the material of the upper and facilitates the manufacturing process.
Figure 7 shows still another embodiment of the present invention which is substantially similar to that shown in Figure 1 except that the bottom end 21 or 22 of the lining sleeve 2 is stitched to the upper 1 along a seam 3' which forms a loop that extends from a toe part 13' to a heel part 14' and returns to the toe part 13' from the heel part 14' .
In fabrication, the lining sleeve 2 is first stitched to the upper 1, and the stitched seams 3, 30a and 30b or the seam 3' formed as such are subj ected to a waterproof ing treatment by using the adhesive tape 31 or 31'. Then, the insole 4 is connected to the upper 1. Finally, the outsole 5 is attached to the upper 1 and the insole 4. The inner liner 6 is placed inside the lining sleeve 2 in a conventional manner.
For economical purposes, the cost of the expensive material of the lining sleeve 2 may be reduced by shortening the dimension of the upper part of the lining sleeve 2. An example of the shortened lining sleeve is shown at 2' in Figure 8 and includes a fabric part 23' stitched to the top open end of the lining sleeve 2' for connection with the top open end of the upper 1. The fabric part 23' is made of a fluid-pervious fabric material.
Since the lining sleeve 2 or 2' is provided with a bottom open end, rather than a bottom wall, the bottom open end of the lining sleeve 2 or 2' can be secured to the upper 1 in a less complicated manner, and the consumption of the expensive waterproof vapor-permeable material can be reduced.
5 As compared to the boot construction disclosed in the basic application of this application, the present invention provides a simpler construction whose drain outlet is not limited to the location where the upper and the lower of the boot are jointed.
SUI~'ARY OF THE INVENTION
An object of the present invention is to provide a waterproof shoe which permits the wearer's feet to breathe and which has a drain outlet for the water invading the interior of the shoe.
Another object of the present invention is to provide a waterproof breathable shoe which can be produced via a less complicated process with reduced consumption of expensive waterproof breathable material.
According to the present invention, a waterproof shoe comprises: an upper including a top open end and a bottom open;end; and a lining sleeve disposed inside the upper, the lining sleeve having a top open end connected to the top open end of the upper, and a bottom open end extending along an inner surface of the upper and ending at a distance from and above the bottom open end of the upper. The bottom open end of the lining sleeve is stitched to the upper to form a seam, and the lining sleeve is made of a material which is impervious to water but is pervious to perspiration vapors .
Waterproof means is attached to the inner surface of the upper and the inner surface of the lining sleeve adjacent to and along the seam so that the water invading the shoe can be diverted to drain out of the shoe through the seam.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to Figures l, 2A, 2B and 2C, a preferred embodiment of the waterproof shoe according to the present invention is shown to include an upper 1 having a toe cap 13 and a counter 14. The toe cap 13 and the counter 14 are stitched to a quarter section 15 of the upper 1 so that a seam 30a is formed between the toe cap 13 and the quarter section 15 and a seam 30b is formed between the counter 14 and the quarter section 15. The toe cap 13 and counter 14 are preferably made of a waterproof material, such as rubber, PVC, PU or a waterproof leather. The upper 1 has a bottom open end lasted to form an inwardly turned bottom flange 12 .
A lining sleeve 2 is disposed inside the upper 1 and has a top open end (not shown) secured to the top open end 11 of the upper 1 in a conventional manner. The lining sleeve 2 is made of a typical material which is impervious to water but pervious to perspiration vapors, and may consist of a shaped single piece, or a plurality of pieces which are connected together via a stitching process followed by a watertight sealing process in a conventional manner. The lining sleeve 2 has a configuration substantially conforming to the interior of the upper 1 but has a bottom open end 21 which ends at a distance from and above the bottom flange 12 of the upper 1 and which extends along and is connected to the seams 30a and 30b. As shown in Figure 2B, a portion of the bottom open end 21 of the lining sleeve 2 extends to the marginal end of the quarter section 15 which overlaps the toe cap 13, and is connected to the quarter section 15 and the toe cap 13 along the seam 30a. As shown in Figure 2C, another portion of the bottom open end 21 of the lining sleeve 2 extends to the other marginal end of the quarter section 15 which overlaps the counter 14, and is connected to the quarter section 15 and the counter 14 along the seam 30b. As shown in Figure 2A, the remaining portions of the bottom open end 21 of the lining sleeve 2 are stitched to the quarter section 15 along seams 3 at the medial and lateral sides of the upper 1. The quarter section 15 has no jointed overlapping parts at the seams 3 . Note that the bottom open end 21 of the lining sleeve 2 does not extend below the intersection of the seams 3 and 30a and the intersection of the seams 3 and 30b.
A waterproof tape 31 is adhesively bonded to the inner surface of the upper 1 and the inner surface of the lining sleeve 2 adj acent to and along the inner side of the stitched seams 3, 30a and 30b. The bottom end of the waterproof tape 31 extends to the bottom flange 12 of the upper 1. The waterproof tape 31 serves to prevent the water invading through the stitched seams 3, 30a and 30b from entering the interior of the lower part of the upper 1 and divert drainage of the invading water to the outside of the shoe through the stitched seams 3, 30a and 30b. The waterproof tape 31 also provides enhanced waterproofness at the bottom end of the upper 1.
The bottom flange 12 of the upper 1 and the bottom end of the waterproof tape 31 are secured to an insole and an outsole 5 by means of a watertight soling process, such as injecting or applying an adhesive, etc. A filler 7 is inserted into an opening confined by the bottom flange 12 of the upper 1 and by the bottom end of the waterproof tape 31 between the insole and outsole 4 and 5. A waterproof cover 8 is provided beneath the f filler 7 . A conventional inner liner 6 which has a shape substantially conforming to that of the inner surface of the upper 1 is disposed inside the lining sleeve 2 in a conventional manner in order to provide comfort and durability. If desired, a foot-like padding (not shown) may be disposed on a bottom wall of the inner liner 6 in a conventional manner.
Although the waterproof tape 31 shown in Figure 2 extends to the bottom flange 12 of the upper 1, the present invention is not limited thereto. As shown in Figure 3, a waterproof tape 31' is formed as a strip that does not extend to the bottom flange 12 of the upper but extends along the stitched seams 3, 30a and 30b. In this case, the quarter section 15 should be made of a waterproof material so as to ensure that the lower part of the quarter section 15 below the strip is waterproof. In place of the waterproof tape 31, 31' a waterproof coating may be applied to the inner surfaces of the upper 1 and the lining sleeve 2 in a conventional manner.
Figure 4 and 5 show other embodiments of the present invention which are substantially similar to those shown in Figures 2 and 3 except that the lining sleeve 2 has a folded bottom end 22 which is turned upward and outward and which is stitched to the upper 1. The folded bottom end 22 can provide an enhanced waterproofing effect as it effectively prevents downward flowing of the invading water.
Figure 6 shows another embodiment of the present invention which is substantially similar to that shown in Figures 1-2C except that the bottom end of the waterproof tape 31" has a dimension greater than that of the bottom flange 12 of the upper 1. The construction as such permits saving of the material of the upper and facilitates the manufacturing process.
Figure 7 shows still another embodiment of the present invention which is substantially similar to that shown in Figure 1 except that the bottom end 21 or 22 of the lining sleeve 2 is stitched to the upper 1 along a seam 3' which forms a loop that extends from a toe part 13' to a heel part 14' and returns to the toe part 13' from the heel part 14' .
In fabrication, the lining sleeve 2 is first stitched to the upper 1, and the stitched seams 3, 30a and 30b or the seam 3' formed as such are subj ected to a waterproof ing treatment by using the adhesive tape 31 or 31'. Then, the insole 4 is connected to the upper 1. Finally, the outsole 5 is attached to the upper 1 and the insole 4. The inner liner 6 is placed inside the lining sleeve 2 in a conventional manner.
For economical purposes, the cost of the expensive material of the lining sleeve 2 may be reduced by shortening the dimension of the upper part of the lining sleeve 2. An example of the shortened lining sleeve is shown at 2' in Figure 8 and includes a fabric part 23' stitched to the top open end of the lining sleeve 2' for connection with the top open end of the upper 1. The fabric part 23' is made of a fluid-pervious fabric material.
Since the lining sleeve 2 or 2' is provided with a bottom open end, rather than a bottom wall, the bottom open end of the lining sleeve 2 or 2' can be secured to the upper 1 in a less complicated manner, and the consumption of the expensive waterproof vapor-permeable material can be reduced.
5 As compared to the boot construction disclosed in the basic application of this application, the present invention provides a simpler construction whose drain outlet is not limited to the location where the upper and the lower of the boot are jointed.
10 While the present invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
