Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to the outsole of indoor footwear such as slippers.

[0002]

[Problems to be solved by conventional techniques and devices]

 Due to changes in lifestyles, the number of flooring dwellings has increased in recent years, and as a result, the frequency of use of indoor footwear such as slippers has increased. There is a demand for indoor footwear that does not slip easily when walking on flooring.

[0003] There are various types of outsole of indoor footwear, and among them, synthetic leather, foams such as sponges, brushed cloth, and the like are used as a material constituting a ground contact surface.

When the ground surface is made of synthetic leather, the surface is flat, so that the surface is slippery especially when the floor surface is painted. Therefore, a non-slip member made of, for example, a brushed cloth is attached to the lower surface of the synthetic leather. However, walking on the rug laid on the flooring could damage the rug due to frictional resistance. In order to avoid such a problem, some anti-slip members have the highest anti-slip effect and are fitted with anti-slip members only at the heel-corresponding part where the stepped foot touches when landing. The anti-slip effect when stepping out could not be expected.

[0005] Even when the ground contact surface is made of a foam such as sponge, it is slippery as in the case of synthetic leather.

When the grounding surface is made of a brushed cloth, a sufficient anti-slip effect can be obtained. However, as described above, when walking on a rug laid on the flooring, There was a risk of damaging the rug due to frictional resistance.

[0007] An object of the present invention is to provide an outsole of indoor footwear in which an anti-slip effect when walking on a flooring is reliably obtained and the rug is not damaged when walking on a rug laid on the flooring. It is in.

[0008]

[Means for Solving the Problems and Effects of the Invention]

 In the outsole of the indoor footwear according to the invention, one or a plurality of non-slip projection-forming elastic bodies are arranged and fixed on the lower surface of the outsole core, the surface is made of a smooth material, and at least one of the surfaces of the outsole core is provided. The covering member that covers the lower surface is joined to the lower surface, so that a non-slip convex portion is formed at a portion corresponding to the elastic body on the lower surface of the covering member.

As described above, the elastic body for forming a non-slip convex portion is arranged and fixed on the lower surface of the bottom core, and at least the lower surface of the bottom core is covered with a covering member made of a material having a smooth surface and joined. By forming the outsole by doing so, it is possible to form a non-slip convex portion on the lower surface of the covering member, that is, on a portion corresponding to the elastic body on the grounding surface. The anti-slip projection has a surface made of a covering member, is smooth, and has a cushioning property by an elastic body. Therefore, when walking on the flooring with the indoor footwear having the outsole according to the present invention, the anti-slip effect can be reliably obtained by the anti-slip projection. In addition, the cushioning effect at the time of walking can be obtained by the elastic body inside the anti-slip projection. Further, since the surface of the anti-slip projection is smooth and has low frictional resistance, there is no risk of damaging the rug when walking on the rug.

[0010] In the outsole of the indoor footwear according to the present invention, it is preferable that at least one of the elastic bodies is fixed to a position on the bottom surface of the outsole core so that the elastic body can be hooked with a toe through the bottom of the indoor footwear.

If at least one of the elastic bodies is fixed at the bottom position of the bottom core as described above, when walking while wearing the indoor footwear according to the present invention, the elastic body is formed on the lower surface of the covering member corresponding to the elastic body. The anti-slip effect at the time of stepping-out can be obtained by the anti-slip projections provided, and at the time of stepping-up, the toe can be hooked on the elastic body via the bottom of the indoor footwear, thereby increasing the gripping force. Walking becomes easier. The position of the bottom surface of the outsole core, which can be hooked with the toe through the bottom of the indoor footwear, is usually the position corresponding to the base of the toe.

[0012] In the outsole of the indoor footwear according to the present invention, all of the plurality of elastic bodies are substantially rod-shaped, and a portion corresponding to a portion of the lower surface of the outsole core corresponding to a portion forward of the arch of the sole. In some cases, they are arranged and fixed in parallel in the front-rear direction so as to be substantially along the width direction of the bottom sole.

According to this configuration, the anti-slip effect at the time of stepping can be reliably obtained by the anti-slip projection formed on the lower surface portion of the covering member corresponding to the elastic body. In this case, one of the plurality of elastic bodies, preferably the foremost elastic body, can be hooked with the toes through the bottom of the indoor footwear, that is, the lower surface of the core of the outsole. However, it is preferable to be fixed at a position corresponding to the base of the toe, thereby providing an effect that, as described above, the grip force at the time of stepping out is increased and walking becomes easier. The shape of the elastic body is not limited to a shape other than a substantially rod shape, and may be, for example, a hemispherical shape.

When all the elastic bodies are arranged as described above, the non-slip member may be fixed to a portion corresponding to the heel of the sole on the lower surface of the covering member.

Since the lower surface of the covering member, that is, the portion corresponding to the heel of the sole on the ground contact surface comes into contact with the flooring and the like when the stepped foot comes down, the non-slip portion of the portion is not arched. It is not always necessary to use a non-slip convex portion having low frictional resistance, such as a portion corresponding to a front portion. Therefore, as described above, if the non-slip member is directly attached to the portion corresponding to the heel, the non-slip effect at the time of landing can be more reliably obtained. Of course, the heel-corresponding portion may be formed with one or more anti-slip projections as described above.

[Embodiment of the invention]

 1 to 3 show one embodiment of the present invention.

As shown in FIGS. 1 to 3, the outsole (10) of the indoor footwear according to the present invention has three elastic members (12) for forming non-slip protrusions on the lower surface of the outsole (11). A covering member (13), which is fixed and has a smooth surface and covers the lower surface, the peripheral surface, and the upper peripheral portion of the bottom core (11), is joined to the lower surface and the upper peripheral portion of the bottom core (11). As a result, a non-slip projection (14) is formed on the lower surface of the covering member (13) at a portion corresponding to the elastic body (12). A non-slip member (15) made of synthetic leather processed into a backskin shape is sewn to a portion corresponding to the heel of the sole on the lower surface of the covering member (13).

The bottom core (11) has a two-layer structure in which a nonwoven fabric (112) is bonded to the lower surface of a paperboard (111).

Each elastic body (12) is a rod having a substantially semicircular cross section made of latex foam, and corresponds to a portion of the lower surface of the outsole core (11) which is forward of the arch of the sole. The parts are arranged and fixed parallel to each other at intervals in the front-rear direction substantially along the width direction of the bottom core (11). The foremost elastic body (12) is fixed to the lower surface position of the outsole core (11), which can be hooked by the toes via the bottom of the indoor footwear, that is, the position corresponding to the base of the toe.

The covering member (13) is made of synthetic leather having a smooth surface. Notches are formed at the front and rear ends and one side of the upper surface covering portion (131) of the covering member (13) to prevent wrinkles from forming at the time of joining.

An example of a method of manufacturing the outsole (10) will be described with reference to FIG. 2. First, a paperboard (11) and a nonwoven fabric (112) are laminated to form an outsole core (11). (See FIG. 2 (a).) Then, three elastic members (12) for forming non-slip convex portions are joined to a portion of the lower surface of the outsole core (11) corresponding to a portion forward of the arch of the sole. (See FIG. 2B). Then, after bonding the covering member (13) to the lower surface and the upper peripheral edge of the bottom sole (11), a non-slip member (15) is attached to a portion corresponding to the heel of the sole on the lower surface of the covering member (13). Sew it with a sewing machine (see Fig. 2 (c)). Thus, as shown in FIG. 1 and FIG. 3, the outsole (10) in which the anti-slip projection (14) is formed on the lower surface of the covering member (13) at the portion corresponding to the three elastic bodies (12). Is obtained.

An indoor footwear (1) using the above outsole (10) is shown in FIGS. The indoor footwear (1) includes a band (4) at a portion along the upper edge of the peripheral surface covering portion (32) of one covering member (3) covering the upper surface, the peripheral surface, and the peripheral edge of the lower surface of the core (2). A notch (34) into which the lower edge of the band (4) can be inserted is formed, the lower edge of the band (4) is inserted into the notch (34), and both sides of the notch (34) are ground-seamed, and the covering member is formed. (3) is formed by joining the upper surface of the core (2) and the peripheral edge of the lower surface, and joining the outsole (10) to the lower surface of the core (2).

When walking on the flooring while wearing the indoor footwear (1), when stepping on, the anti-slip effect is obtained by the anti-slip projections (14), and the toes are placed on the bottom of the indoor footwear (1). It can be hooked on the front elastic body (12) via the top cover (31), the core (2) and the outsole (10) of the covering member (3), thereby increasing the gripping force. It makes walking easier. Also, at the time of landing, the anti-slip effect can be reliably obtained by the anti-slip member (15). On the other hand, when walking on the rug laid on the flooring while wearing the indoor footwear (1), the anti-slip effect is obtained in the same manner as described above by the anti-slip convex portion (14) and the anti-slip member (15). The surface of the anti-slip projection (14) formed on the part corresponding to the front part of the sole where the force is applied when stepping out, rather than the arch, is composed of the smooth surface of the covering member (3), There is no risk of damaging the rug due to resistance.
