  The replacement shoe sole formed by felt or the like described above is appropriately distorted according to the ground to prevent slipping, but when the adhesive that bonds the surface fastener is cured, the shoe sole is gradually bent by repeated strain of the shoe sole. There is a problem that wrinkles occur and the adhesive strength decreases. In addition, when the sole is worn out and thinned from the vicinity of the sole having a large distortion, the surface fastener around the sole rises from the sole or turns over, making walking uncomfortable.

  For this reason, in a shoe having a shoe sole that can be attached and detached with a hook-and-loop fastener, it is desirable to have a structure that prevents these lifting and turning and can maintain the attachment state of the shoe sole for replacement and the hook-and-loop fastener.

  The present invention has been made based on the above-described problem, and an object of the present invention is to provide a shoe having a shoe sole that can be attached and detached with a hook-and-loop fastener and capable of maintaining the mounting state of the replacement shoe sole and the hook-and-loop fastener. .

In order to achieve the above-described object, the shoe according to the present invention is configured such that the shoe sole is detachable with a hook-and-loop fastener, and a seat member having the hook-and-loop fastener on the mounting base is sewn by a sewing thread. They are wearing, and said mounting base to the bottom the sewing thread in installing an additional covered.

  In the shoe having the above-described configuration, the shoe sole replaceable with respect to the shoe main body is sewn with a sheet member having a hook-and-loop fastener on the mounting base. In this way, by fixing the hook and loop fastener by sewing, the joint strength can be improved and the mounting state of the hook and loop fastener can be maintained over a long period of time, and a certain amount of distortion of the shoe sole is allowed. Comfort is not reduced.

  ADVANTAGE OF THE INVENTION According to this invention, the shoe which can maintain the attachment state of a shoe sole and a hook-and-loop fastener in the shoe which has a shoe sole which can be attached or detached with a hook-and-loop fastener is obtained.

Hereinafter, embodiments of shoes according to the present invention will be described.
1 to 4 are views showing an embodiment of a shoe according to the present invention, FIG. 1 is a cross-sectional view, and FIG. 2 is a cross-sectional view showing a state in which a shoe sole is removed from the shoe shown in FIG. 3 is an enlarged cross-sectional view of a toe portion, and FIG. 4 is a perspective view showing a configuration of a shoe sole.

The shoe 1 according to this embodiment includes a shoe main body 5 and a shoe sole 50 that can be attached to and detached from the shoe main body 5.
The shoe body 5 has a trunk portion 6 that surrounds a foot inserted from the insertion port 6a, and a midsole 7 attached to the bottom side thereof, and the bottom side of the midsole 7 is detachable. It is an attachment portion for the shoe sole 50. A hook-and-loop fastener (male) 8 is provided on the back surface of the insole 7, and a peripheral wall 7 a is formed around the mounting portion of the shoe sole 50 so as to surround the mounting portion of the shoe sole 50.

  The surface fastener (male) 8 on the shoe main body side provided on the back surface of the insole 7 is a sheet in which a fastener (male) 8 a having a number of hook-shaped locking portions is formed in substantially the same shape as the insole 7. The sheet member 8b is configured to be formed on the member 8b, and the sheet member 8b is bonded to the back surface side of the insole 7 with, for example, an adhesive. In FIG. 3, an adhesive layer made of an adhesive is indicated by reference numeral 10.

  On the other hand, the shoe sole 50 that can be attached to and detached from the shoe main body 5 includes a surface fastener (female) 51 that is engaged with the surface fastener (male) 8. The surface fastener (female) 51 has a configuration in which a fastener part (female) 51a having a large number of loop-shaped locking parts is formed on a sheet member 51b formed in substantially the same shape as the insole 7 and the mounting base 53. The sheet member 51b is adhered to the upper surface side of a plate-like attachment base 53 having a shape substantially matching the shoe sole by sewing and adhesion. In FIG. 3, an adhesive layer made of an adhesive is indicated by reference numeral 60.

  And the sheet | seat member 51b which comprises the hook and loop fastener (female) 51 is a thread | yarn (sewing thread | yarn of synthetic resin fibers, such as nylon, along the periphery of the attachment base 53, as shown in FIG. ) Sewn by S.

  In this embodiment, the attachment base 53 is formed of felt (however, it may be formed of synthetic resin or rubber), and the sewing thread S to which the hook and loop fastener (female) 51 is attached is attached to the attachment base 53. And is sewn so as to be exposed to the bottom side of the mounting base 53.

  Compared to the case where the hook and loop fasteners are attached only to the bottom of the felt, the hook and loop fastener (female) 51 is fixed by sewing as described above, thereby improving the bonding strength in addition to the bonding by the adhesive layer 60. I can plan. In addition, when the periphery of the surface fastener 51 and the mounting base 53 is sewn, even in the shoe sole 50 that is worn down and thinned and greatly distorted, the sewing thread S changes its tension state according to the distortion, and is joined. In order to maintain, the turn-up of the hook-and-loop fastener (female) 51 around the shoe sole 50 is blocked by the sewn portion, and the hook-up state of the hook-and-loop fastener can be maintained over a long period of time, and a certain degree of distortion of the shoe sole is allowed. As a result, it is possible to prevent a decrease in comfort. Further, the attachment strength can be improved by attaching the sewing thread S so as to penetrate the attachment base 53. In the attachment base 53, a recess 53a is formed in advance at the portion where the sewing thread S appears, or the attachment base 53 is deformed by the tension of the sewing thread S by sewing to form the recess 53a. Preferably, the sewing thread S is housed in the recess 53a in a sewn state. In this way, by forming the recess 53a and positioning the sewing thread S, the surface side of the sewing thread S is not exposed and can be prevented from being cut, and further, from within the recess 53a. A rubber elastic material, which will be described later, easily flows into the insertion hole 53b formed by the sewing thread S, and the sewing state can be strengthened.

  As described above, the attachment base 53 to which the surface fastener (female) 51 is attached is attached to the upper surface side of the bottom portion 55.

  The bottom portion 55 of the present embodiment is formed of a felt formed by pressing an aggregate of fibers such as synthetic resin fibers and natural fibers, and the fibers are intertwined at random to form a plate shape. Of course, the bottom 55 may be formed of other materials, for example, rubber / synthetic resin, or may be attached with spikes or the like so as to further improve the anti-slip effect.

  In the present embodiment, the mounting base 53 is adhered to the upper surface side of the bottom portion 55 with a rubber elastic layer 57 interposed therebetween. In this case, the rubber elastic layer 57 is formed of a polymer compound exhibiting rubber elasticity such as natural rubber, synthetic rubber, and thermoplastic elastomer, and the attachment base 53 formed of the felt on the upper surface side and the bottom surface side thereof. And the bottom 55 are impregnated between the fibers (the portion impregnated between the fibers is indicated by symbol A). In this manner, the portion of the rubber elastic layer 57 impregnated between the fibers of the mounting base 53 and the bottom 55 has irregular irregularities as shown in FIG. 3, and the felt fibers are taken in and held in the irregularities. Therefore, the rubber elastic layer 57, the mounting base 53, and the bottom portion 55 are in a state in which peeling is effectively prevented at the boundary portions.

  When the attachment base 53 and the bottom portion 55 are pasted through the rubber elastic layer 57, the sewing thread S that appears on the bottom surface side of the attachment base 53 is covered with the bottom portion 55, so that the ground 55a of the bottom portion 55 is covered. The sewing thread does not appear, and the hook and loop fastener (female) 51 is securely held on the mounting base 53 in a state where fraying is prevented. Further, since the surface fastener (female) 51 has an adhesive layer 60 made of an adhesive in addition to being sewn to the attachment base 53 by the sewing thread S, the attachment base 53 and the surface fastener (female) 51 are provided. The opposing surfaces of each other are effectively attached. Therefore, even if the periphery of the shoe sole 50 is worn out and distortion increases, and the joint strength between the attachment base 53 and the hook-and-loop fastener (female) 51 is reduced, the center portion of the shoe sole 50 is prevented from being covered by the sewn portion. Is done.

  If the attachment base 53 is made of felt, it is deformed according to the tension state of the sewing thread S, so that the sewing thread S can be prevented from being cut, and the attachment base 53 and the bottom 55 are made of the same material (felt). Therefore, the distortion of the shoe sole is maintained without impairing the flexibility of each other. Further, the sewing thread S that appears on the bottom side of the mounting base 53 is covered with a rubber elastic layer 57, and this rubber elastic layer also penetrates into the recess 53a and the insertion hole 53b on the bottom side of the mounting base 53. Therefore, the sewing thread is protected and thread breakage is prevented.

  When the mounting base 53 to which the above-described surface fastener (female) 51 is attached is attached to the bottom 55, for example, a rubber-like elastic layer forming material made of rubber or synthetic resin is interposed between the two. Then, it is melted by heating and pressing, impregnated between the two, and then solidified by leaving it at room temperature or cooling. As described above, since the attachment base 53 and the bottom portion 55 are attached via the rubber elastic layer 57, the distortion of the shoe sole is not restricted as compared with a configuration in which the attachment is performed with a conventional adhesive. . Moreover, since it has rubber elasticity unlike the hardened | cured adhesive agent, a joining part comes to last long.

  A shoe that can be exchanged by removably engaging a surface fastener (female) 51 on the shoe sole side with a surface fastener (male) 8 of the insole 7 (on the shoe body side) configured as described above. The bottom 50 is accommodated in a mounting portion surrounded by a peripheral wall 7 a that hangs around the midsole 7. And when the bottom part 55 is worn out, the shoe sole 50 is replaced.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to above-described embodiment, It can change variously. For example, the attachment base 53 and the bottom portion 55 may be attached by an adhesive instead of the rubber elastic layer, or may be integrally formed. Further, the sheet member 51b of the hook and loop fastener (female) 51 is adhered to the attachment base 53 by the sewing thread S, and an adhesive layer 60 made of an adhesive is provided between them. Various other adhesives can be used, such as those that are cured by volatilization of the solvent and those that are melted by heat and bonded and solidified at room temperature. Further, for the hook and loop fasteners 8 and 51, the shoe body side may be a female type and the shoe sole side may be a male type. Further, the hook and loop fastener (female) 51 and the mounting base 53 are sewn at least around the toes and the heel, but the circumference of the shoe sole 50 may be sewn over the entire circumference, and not only the circumference but also the center side As a result, the joint state between the two can be reliably maintained.
