FIG. 10 is a perspective view illustrating a shoe according to an embodiment of the present invention.
As shown in FIG. 1, the shoe 10 according to an embodiment of the present invention comprises an upper layer 11, a bottom layer 12, a sole cover 13, a sole 17 (shown in FIG. 5) and an insert 18.
Here, the upper layer 11 may be made from a material such as leather, artificial leather, cloth, etc. to cover the upper side of a shoe. The upper layer 11 has an opening 11 a open on its lower side. The upper layer 11 is made in an upper layer process. It is made in a 3D shape through a sewing and bonding process using a single piece or multiple pieces of materials. It may be made in a single layer structure or may be made in a two-layer or more layer structure in such a way to bond an inner skin and an outer skin on an inner side and an outer side.
The bottom layer 12 may be made from leather, artificial leather, cloth, etc. and may include a single or a plurality of materials as a member designed to cover the bottom of the foot by covering the upper layer.
The sole cover 13 may be made from leather, artificial leather, cloth, etc. and extends from the lower side of the upper layer 11 and is designed to cover the surroundings of the sole 17 (shown in FIG. 5). It may be formed of two materials like in the embodiment of the present invention. The materials may have a rim shape matching with the rim of the lower side of the upper layer 11. For consistency with the upper layer 11, the sole cover 13 may be manufactured in such a way that the surface 13C (shown in FIGS. 2 and 6) to be turned inside out when the shoe 10 is almost finished has the same color and is made from the same material as the surface of the upper layer 11.
In the upper layer, the edge of the bottom layer 12 and the rim of the lower side of the sole cover 13 are sewed along the rim of the lower side of the upper layer 11. At this time, the sole cover 13 is sewed on the rim of the lower side of the upper layer 11 in a state that the sole cove 13 is positioned on the outer surface of the upper layer 11. Here, the lower sides of the upper layer 11 and the sole cover 13 represent the sides which face the ground in the course of the typical use of the shoes 10, the term will have the same meaning in the following descriptions.
The sole 17 (shown in FIG. 5) is a key member belonging to the bottom of the shoe 10 and is made from a material such as a synthetic resin, etc. which has a cushioning function and is attached to beneath the bottom layer 12.
The sole cover 13 is turned inside out in the downward direction to face the sole 17 and is attached surrounding the outer circumferential surface and the rim of the lower side of the sole 17 (shown in FIG. 5) along with the cushion member 14 15, 16 (shown in FIG. 5). At this time, the sole cover 13 may be bonded to the side surfaces of the cushion members 14, 15, 16 and the sole 17 and may be also bonded to beneath the sole 17, respectively.
The insert 18 is positioned at the lower most portion of the shoe 10 and comes into contact with the ground when in use and may include a heel which raises the height of the heel portion of the shoe 10, higher than the front side of the shoe. The insert 18 is bonded to beneath the sole 17 including the end portion 13 a of the sole cover 13 and may have different shapes and sizes depending on the user or the desired function.
As shown in FIG. 5, cushion members 14, 15, 16 are disposed between the bottom layer 12 and the sole 17 and are bonded between them.
The cushion member 14, 15, 16 comprises a cushion pad 14 which has an air layer attached to a foot heel beneath the bottom layer 12 and is made from a cushion absorption material, a silicon pad 15 which is made from silicon attached to beneath the bottom layer 12 including the cushion pad 14 or the like, and a memory foam 16 which is attached to beneath the silicon pad 15.
FIGS. 2 to 7 are views for describing the method for manufacturing shoes according to an embodiment of the present invention.
The method for manufacturing shoes according to an embodiment of the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 2, the upper layer 11, the bottom layer 12 configured to block the lower side of the upper layer 11, and the sole cover 13 extending from the lower side of the upper layer 11 and covering the surroundings of the sole are manufactured in the course of the upper layer process wherein to perform cutting, bonding and sewing.
As shown in FIG. 3, the edge of the bottom layer 12 and the rim of the lower side of the sole cover 13 are sewed along the rim of the lower side of the upper layer 11 and are connected. At this time, the method or connecting the upper layer 11, the bottom layer 12 and the sole cover 13 comprises a step for sewing the rim of the lower side of the upper layer 11 and the edge of the bottom layer 12 and for connecting them, and a step for sewing the rim of the lower side of the sole cover and the rim of the lower side of the upper layer 11 in a state that the sole cover is positioned on the outer surface of the upper layer 1 and for connecting them. As shown in FIG. 4, the sewing process is conducted in such a way that the upper layer 11 and the sole cover 13 are sewed by a sewing needle 2 as the upper layer 11 connected to the bottom layer 12 by a sewing is forced to pass through between an upper roller 1 and a lower roller 3 along with the sole cover 13.
As shown in FIG. 5, the sole 17 may be bonded to beneath the bottom layer 12 by bond. At this time, the cushion member 14, 15, 16 is attached to beneath the bottom layer 12 before the sole 17 is attached to beneath the bottom layer 12, and the sole 17 is attached to beneath the cushion member 14, 15, 16. At this time, a wooden pattern 4 may be installed in the upper layer 11. The cushion member 14, 15, 16 may comprise a cushion pattern 14 attached to the heel of the foot beneath the bottom layer 12, a silicon pad 15 which is attached to beneath the bottom layer 12 including the cushion pad 14, and a memory foam 16 which is attached beneath the silicon pad 15.
As shown in FIG. 6, when the sole 17 is attached, the sole cover 13 is turned inside out in the downward direction to face the sole 17, and the surface 13 b (shown in FIG. 2) positioned outside the sole cover 13 is positioned inside, and the surface 13 c positioned inside is positioned outside, and the sole cover 13 is attached surrounding the outer surface and the rim of the lower side of the sole 17 including the cushion members 14, 15, 16 (shown in FIG. 5). Therefore, the end portion 13 a of the sole cover 13 extends up to the rim of the lower side of the sole 17 and is bonded. If the sole cover 3 is turned inside out to face the sole 17, the sewed portions of the sole cover 13, the upper layer 11 and the bottom layer 12 become hidden from outside, so they cannot be seed from outside.
As shown in FIG. 7, when the sole cover 13 is bonded, the insert 18 is bonded to beneath the sole 17 (shown in FIG. 16) including the end portion 13 a (shown in FIG. 6) of the sole cover 13.
In the shoe and method for manufacturing the same according to the present invention, the shoe making process can be made simpler, saving time and efforts, and the quality of shoes can be enhanced.
As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described examples are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
