Description

The present invention relates to a slipper mainly intended for indoor use.

  Conventionally, slippers that are mass-produced industrially have (a) a process of cutting material, (b) a process of making a lower bottom part that is in contact with the ground, and (c) a crust part that is a part covering the instep of the foot. Molding and bonding to a thin plate-shaped base to make the upper base, (d) Making the insole that is in contact with the sole of the foot, (e) Special lower bottom and upper base This is manufactured through a process of sewing and joining with a sewing machine, and a process of attaching and finishing the insole part by bonding to the part formed in the step (e).

Specifically, in the step of cutting the material (a), the bottom plate 50, the insole core 71, the heel molding member 79, the upper 63 of the upper part and the interlining shown in FIGS. About 10 kinds of materials were punched and cut using a press.
(B) In the step of making the lower bottom portion, as shown in FIG. 1, for example, a leather base plate 50 made of EVA (ethylene / vinyl acetate copolymer resin) or the like is used for reinforcement and to give a high-class feeling. The lower bottom portion 55 was manufactured by coating with a coating material 53 made of PVC (vinyl chloride) or the like whose surface was processed.
In the step (c) of forming the upper base, first, as shown in FIG. 1, the upper base 63 is prepared. First, it is made of a synthetic resin material such as EVA on the back surface of the upper shell 60 that forms the outer surface of the upper portion 6 (see FIG. 3) of the slipper, which is cut into a predetermined shape in the cutting step (a). Bond the interlining 60a. This is because the upper surface 60, which is the outer surface of the upper part 6 of the slipper, is usually made of a cloth, but the cloth is generally not self-supporting, and the upper part 6 will sag only with the cloth. It is lined with a ground 60a to provide self-supporting and shape-retaining properties. Furthermore, if the mesh ground 60b for improving the touch when worn is bonded on the interlining 60a and the terminal of the mouth is processed, the upper base 63 is completed. When the upper base 63 is completed, a special machine called a lifting machine is used to place the upper base 63 on the thin base 61 made of cardboard, for example, as shown in FIG. The upper base 65 was manufactured by thermoforming into a three-dimensional shape to cover and bonding.

  (D) In the step of making the insole portion, as shown in FIG. 2A, first, the heel side portion 75b is compared with the toe side portion 75a at the portion corresponding to the heel in the core material 71 made of cardboard or the like. A heel molding member 79 made of, for example, EVA (ethylene / vinyl acetate copolymer resin) for increasing the thickness is bonded. On the other hand, the insole surface material 73 that forms a part directly in contact with the sole of the foot is a cloth reinforced with interlining, or a tatami-like reinforced with interlining as a summer specification as shown in FIG. Prepare from sheet material. Then, as shown in FIG. 2B, the insole surface material 73 is adhered and pasted to the upper surface side of the core material 71 in a state where the heel forming member 79 is bonded, and the peripheral portion 75c including the side surface is illustrated in FIGS. As shown in FIG. 2, the insole portion 75 was completed when covered with the border material 8 such as a bias tape.

  In the step (e), as shown in FIG. 3, the lower base 55 manufactured in the step (b) and the base 61 of the upper base 65 manufactured in the step (c) are combined into a special machine called an eight-way sewing machine. It was sewn and combined with a sewing machine.

  In the finishing step (f), as shown in FIG. 3, the insole portion 75 manufactured in the step (d) is bonded to the base portion formed in the step (e), and the slipper 80 shown in FIG. It was completed.

  That is, the conventional slipper 80 is roughly divided into three components, namely, the lower bottom portion 55, the upper base portion 65, and the insole portion 75, from about 10 kinds of materials, respectively, (b), (c), It was manufactured in the step (d) and the resulting parts were combined in the steps (e) and (f).

  As described above, the conventional slippers are manufactured by using a large number of materials and through a number of processes, and these processes are performed by using a special machine such as the process (e). Since the process which requires this technique was included, there existed a limit in reducing the cost concerning manufacture.

  However, there is always a need in the market for slippers that can be manufactured at a lower cost.

  Therefore, an object of the present invention is to provide a slipper that can be manufactured at a lower manufacturing cost.

The slipper according to the present invention is a slipper comprising a lower bottom part that is in contact with the ground, a crust part that is a part that covers the back of the foot, and an insole part that is a part that is in contact with the sole of the foot,
From the synthetic resin material having flexibility, the lower bottom part is formed into a shape in which the toe side part is thin and gradually increases in thickness toward the heel side part,
The upper part is composed of a lower base, and an upper part is formed and bonded to a three-dimensional shape so as to cover the upper part of the foot.
The insole portion is configured in a flat plate shape having a substantially uniform thickness from the toe side to the heel side,
The lower bottom part, the base of the upper base part, and the insole part are laminated in order and bonded together.

  According to the slipper configured as described above, since the lower bottom portion is only molded from a synthetic resin material into a predetermined shape, the bottom plate 50 in the conventional process (b) is made of PVC (vinyl chloride) or the like. The step of covering with the covering material 53 by adhesion can be omitted, and it is not necessary to prepare the covering material 53 on the material side, and the number of parts can be reduced.

  Further, the lower bottom portion is formed in a shape in which the toe side portion is thin in advance and gradually increases in thickness toward the heel side portion, and replaces the heel forming member 79 incorporated in the insole portion 75 according to the conventional manufacturing method. Since it is set as an aspect, the number of parts of an insole part can be reduced by the amount of the heel shaping | molding member 79, and the process which adheres and affixes the heel shaping | molding member 79 to the core material 71 also in the manufacturing process of an insole part is abbreviate | omitted. be able to. In addition, since the insole portion does not include the heel molding member 79, the insole portion has a flat plate shape with a substantially uniform thickness from the toe side portion to the heel side portion. For this reason, conventionally, the work of incorporating the heel forming member 79 and covering the peripheral portion 75c of the insole portion 75 having different thicknesses of the toe side portion 75a and the heel side portion 75b with the border material 8 such as a bias tape is complicated. However, the operation of covering the peripheral edge portion including the side surface of the insole portion with the edging material becomes much easier.

  Further, the slipper according to the present invention is manufactured by sequentially laminating the lower bottom portion, the base of the upper base portion, and the insole portion in order, and in the conventional process (e), It is possible to omit the process that requires skill, such as sewing the lower base 55 and the base 61 of the upper base 65 with a special sewing machine called an eight-way sewing machine, and to make it much easier than before. Can do.

  Therefore, the slipper according to the present invention can be manufactured with fewer steps from parts having a smaller number of parts as compared with the slipper 80 according to the conventional manufacturing method, and thus can be manufactured at a lower cost.

  In the slippers described above, the upper base material may be made of a sheet material made of a synthetic resin material having flexibility and having a surface as a decorative surface. According to this, compared with the conventional upper base material 63 formed by adhering the synthetic resin interlining 60a and the mesh base 60b to the back surface of the upper covering 60 made of cloth or the like, the interlining Since the surface of 60a is directly decorated and the upper surface material 60 and the mesh ground 60b are omitted, the number of parts is further reduced, and the upper surface material 60, the interlining 60a, and the mesh ground 60b are reduced. The step of bonding can be omitted. However, considering the feel when worn, even if it is not tailored to one sheet of the above-mentioned sheet material, the upper surface material constituting the outer surface when worn, and the mesh ground, etc. The upper surface material may be composed of a sheet material with a surface made of a synthetic resin material having flexibility and a decorative surface. . Even in this case, the upper surface material 63 made of a conventional fabric or the like is not necessary because the upper surface material has a decorative surface.

  If the upper base material of the slipper is made of a flexible synthetic resin material and is made of a sheet material with a decorative surface on the surface, if the upper base material is provided with a large number of holes, the air permeability Can be secured.

  In the slipper described above, the synthetic resin material constituting the lower bottom and the upper base material or the upper surface material is preferably EVA (ethylene / vinyl acetate copolymer resin) because of its low cost.

It is a figure which shows the manufacturing process of the conventional slipper. It is a figure which shows the manufacturing process of the conventional slipper.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  The slipper S of the present invention shown in FIG. 5 includes a lower bottom part 5 that is a part in contact with the ground, a upper part 6 that is a part that covers the back of the foot, an insole part 20 that is a part that is in contact with the sole of the foot, Is provided.

  The bottom 5 is made of, for example, a synthetic resin material having flexibility such as foam of EVA (ethylene / vinyl acetate copolymer resin), as shown in FIG. 8A and FIG. It is formed into a shape that gradually increases in thickness over the heel side 5b. Although illustration is omitted, the bottom surface 5c of the lower bottom portion 5 is provided with uneven processing to prevent slipping. As will be described later, the lower bottom 5 is manufactured by die cutting using a press.

  The upper part 6 that covers the upper part of the foot is composed of an upper base 13 of the upper part 10 that is a constituent member of the slipper S, as will be described later. In this embodiment, the upper base 13 is composed of a sheet material 32 made of a synthetic resin having flexibility, such as foamed EVA (ethylene / vinyl acetate copolymer resin), for example, similar to the lower bottom portion 5. The sheet material 32 is made of a material having such a thickness as to have a self-supporting property and a shape-retaining property so that the upper portion 6 does not sag when the slipper S is completed. 13) is a single sheet of synthetic resin sheet material 32 that is not lined with an interlining or the like. The surface 6a (13a) of the upper part 6 (skin base material 13) is a decorative surface 6d (13e) to which a decoration such as a color or a pattern is applied. This is because the above-mentioned synthetic resin sheet material 32 is used. They are colored or decorated on the surface of the sheet material 32 by direct printing. Further, the upper portion 6 (upper base material 13) of the present embodiment is provided with a number of holes 6b (13b) that are previously punched to ensure air permeability. A terminal portion 6c, which becomes a slipper when the slipper S is put on, is covered with an edge member 8 such as a bias tape and cleaned. In addition, although the upper part 6 of this embodiment is made into the shape which covers to a toe, of course, the shape to which the toe was opened can also be considered.

  As shown in FIG. 7, the insole portion 20 is configured by adhering an insole surface material 23, which is a portion in contact with the sole of the foot, and a core material 21 made of, for example, thin cardboard. As shown in FIG. 8B and FIG. 9, it is configured in a flat plate shape having a substantially uniform thickness from the toe side portion 20a to the heel side portion 20b. This is because the lower bottom portion 5 is previously formed with the heel side portion 5b thicker than the toe side portion 5a, so that the heel forming member 79 used in the insole portion 75 by the conventional manufacturing method is provided. This is because they are not used. The insole surface material 23 in the present embodiment uses a tatami-like material as a summer specification, and the peripheral portion 20c after being bonded to the core material 21 is covered with an edge material 8 such as a bias tape. Has been.

  Next, the manufacturing method of the slipper S of this embodiment is demonstrated.

  The slipper S is roughly divided into three components, that is, a lower bottom part 5, an upper base part 10, and an insole part 20, and the manufactured lower base part 5, upper base part 10, and insole part 20 are respectively provided. Manufactured by sticking together.

  First, the lower bottom portion 5 is made of a synthetic resin material having flexibility such as foam of EVA (ethylene / vinyl acetate copolymer resin) by using a press machine or the like, as shown in FIG. It is manufactured by thinning the part 5a and forming it into a shape gradually increasing in thickness over the heel side part 5b. In parallel with this, the parts of the upper base 10 and the insole 20 are prepared by die cutting with a press.

  Next, the upper base part 10 which comprises the upper part 6 is manufactured. Similar to the upper base 65 of the slipper 80 according to the conventional manufacturing method, the upper base 10 includes the upper base 13 and the base 15. As described above, the upper base 13 is made of the same material as the lower bottom 5, for example, the sheet material 32 made of a synthetic resin material having flexibility such as foamed EVA (ethylene / vinyl acetate copolymer resin). It is prepared by cutting into a predetermined shape in the cutting process. In addition, as mentioned above, the upper base 13 is made of a single sheet material 32, and the surface 13a is a decorative surface 13e with decoration such as a color or a pattern. In addition, the sheet material 32 is used in which a large number of holes are provided in advance by punching, and the upper base 13 is provided with a large number of holes 13b. The terminal portion 13c serving as a mouth when the slipper S is put on is covered with an edge member 8 such as a bias tape. In the cutting process described above, the base 15 is cut from a thin cardboard, and, as will be described later, in the completed state of the slipper S in which the lower base 5, upper base 10 and insole 20 are bonded together. It is cut into a size slightly smaller than the lower bottom part 5 and the insole part 20 so as not to be seen from the side. The base 15 and the upper base 13 are covered with the upper base 13 by using a machine called a lifting machine as in the conventional slipper manufacturing process (c). The upper shell base portion 10 is completed by bonding with an adhesive such as a latex adhesive while thermoforming into a three-dimensional shape.

  Next, as shown in FIG. 7, the insole portion 20 is manufactured by bonding the insole surface material 23 made of a tatami-like sheet material to the core material 21 described above. Here, it is not necessary to adhesively attach the molding member 79 to the core material 21, which has been adhesively adhered to the core material 71 by the conventional manufacturing method. This is because the lower bottom portion 5 is molded in advance with the heel side portion 5b having a thickness as compared with the toe side portion 5a. Then, as shown in FIG. 8B, the insole portion 20 is completed when the peripheral edge portion 20c after bonding is covered with the border material 8 such as a bias tape over the entire circumference. In addition, although the slipper S of this embodiment uses the tatami-like material for the insole surface material 23 as a specification for summer, other materials such as cloth are used as the insole surface material 23 according to the design. Of course, in that case, a cushioning material such as urethane may be sandwiched between the insole surface material 23 and the core material 21 so as to provide soft comfort. In addition to the bias tape, a cloth made of the same material as the insole surface material 23 or the like may be used for the border material 8 that covers the peripheral edge portion 20c of the insole portion 20.

  In the next step, the lower bottom part 5, the upper base part 10 and the insole part 20 thus prepared are bonded together by bonding. First, the lower bottom 5 and the base 15 of the upper base 10 are bonded and bonded together using an adhesive such as a latex adhesive as shown in FIG. Thereafter, as shown in FIG. 8B, the insole portion 20 is placed on the upper surface of the base 15 of the upper base portion 10 and is similarly bonded using an adhesive such as a latex adhesive. S is completed.

  According to the slipper S configured as described above, the lower bottom portion 5 is only formed into a predetermined shape from a synthetic resin material such as EVA, so that the bottom plate 50 in the conventional process (b) is made of PVC ( The step of covering with a covering material 53 made of vinyl chloride or the like can be omitted, and it is not necessary to prepare the covering material 53 on the material side, and the number of parts can be reduced.

  Further, the lower bottom portion 5 is formed in a shape in which the toe side portion 5a is thin and the thickness is gradually increased toward the heel side portion 5b, and the heel forming member 79 is built in the insole portion 75 according to the conventional manufacturing method. Therefore, the number of parts of the insole portion 20 can be reduced by the heel molding member 79, and the heel molding member 79 is adhered and pasted to the core material 71 in the manufacturing process of the insole portion 20. The step of performing can be omitted. In addition, since the insole portion 20 does not include the heel forming member 79, the insole portion 20 has a flat plate shape with a substantially uniform thickness from the toe side portion 20a to the heel side portion 20b. For this reason, conventionally, the work of incorporating the heel forming member 79 and covering the peripheral portion 75c of the insole portion 75 having different thicknesses of the toe side portion 75a and the heel side portion 75b with the border material 8 such as a bias tape is complicated. However, the operation of covering the peripheral edge portion 20c including the side surface of the insole portion 20 with the edging material becomes much easier.

  Further, the slipper S is manufactured by sequentially laminating the lower bottom portion 5, the base 15 of the upper base portion 10, and the insole portion 20 and integrally bonding them, so that in the conventional process (e) In addition, it is possible to omit a step requiring skill, that is, sewing the lower base 55 and the base 61 of the upper base 65 with a special sewing machine called an eight-way sewing machine. Can be manufactured.

  Therefore, the slipper S according to the present embodiment can be manufactured at a lower cost because the slipper S can be manufactured from a smaller number of parts as compared with the slipper 80 according to the conventional manufacturing method, with fewer steps.

  In particular, in the embodiment described above, the upper base 13 of the upper base 10 constituting the upper base 6 is made of a synthetic resin material having flexibility such as EVA, and the surface 13a is the decorative surface 13e. Compared with the upper base 63 made of a single sheet material 32 and made by adhering a synthetic resin interlining 60a and a mesh 60b to the back surface of the upper surface 60 made of cloth or the like. Then, the surface of the interlining is directly decorated, and the upper skin 60 and the mesh 60b are omitted. For this reason, the number of parts can be further reduced, and the process of bonding the upper skin material 60 to the interlining 60a and the mesh base 60b can be omitted. However, in consideration of the feel when worn, the upper surface material constituting the outer surface of the upper base material 13A when worn as shown in FIG. 14 and a shell backing 18 (for example, a mesh ground) that is bonded to the back surface of the upper shell 14, the upper shell 14 is made of a flexible synthetic resin material, May be configured from a sheet material 32 having a decorative surface 14e. Even in this case, the upper surface material 63 made of a conventional cloth or the like is not necessary because the upper surface material 14 has the decorative surface 14e.

  Further, the upper base material may not necessarily be a sheet material made of a synthetic resin material, but may be one in which an upper surface material 60 made of fabric is lined with an interlining 60a or the like, as in a conventional slipper 80. . Even in this case, since the number of parts and processes are reduced in the manufacturing process of the lower bottom part 5 and the manufacturing process of the insole part 20, a slipper can be manufactured at a lower cost than before.

  In addition, the slipper S of the embodiment of the present application has summer specifications, the insole surface material 23 of the insole portion 20 is a tatami-like material, and the shell base material 13 has a large number of holes 13b for ensuring air permeability. Although described as being provided, in the case where heat retention is taken into consideration, a configuration in which the hole 13b is not provided may be employed.

  In the above embodiment, the synthetic resin material used for the lower bottom portion 5 and the upper base material 13 (upper surface material 14) is described as EVA (ethylene / vinyl acetate copolymer resin) with low cost. It is good also as comprising a bottom bottom part and a shell base material with a raw material.
