DETAILED DESCRIPTION OF THE INVENTION
The basic structure of the slipper consists of a bottom plate and an upper shell. The slipper's upper is usually lifted up in an arc. The slipper of the present invention is characterized in that the upper has a flat surface whose two longitudinal sides are parallel. The shape of the upper may be a shape in which the toes are vacant or not. Regardless of the shape, this flat surface overlaps the bottom plate during storage, so that it can be stored compactly in a flat state. This flat surface remains flat with no folds or creases, so it can be restored immediately in use to ensure a wide and large mouth opening. When the upper is made of a relatively thin and lightweight material, this flat surface has a function to stably support the upper by lifting up an arc when used.
[0006]
The instep of the slipper of the present invention has a flat surface whose two sides in the longitudinal direction are parallel to each other, and it is preferable that the two sides are constituted by folds of folds. By attaching the fold ridges firmly, the flat surface can be secured as stable. By applying sewing along the valleys of the folds and / or applying sewing along the two sides in the longitudinal direction, the flat surface can be secured more stably. In addition, by firmly attaching the folds, the flat surface of the upper is elastically supported to ensure its stability.
[0007]
The depth of the fold is gradually reduced toward the toe side. By gradually decreasing the depth of the fold fold toward the toe side, the edge on the cuff side of the flat surface forms the upper surface of the cuff opening, together with the cuff edge on the cuff side of the two fold folds A wide and large mouth opening can be secured.
In the slipper of the present invention, the bottom plate and the upper shell are preferably made of a relatively light and thin material. The slipper according to the present invention is a slipper made of a relatively lightweight and thin material, which is made of a relatively light and thin material, and includes a bottom plate and a cover that is attached or adhered to the front surface thereof. The aspect which gave is included.
Here, the sewing machine hook may be one strip when the bottom plate of the slipper is made relatively thin, but when the bottom plate is made relatively thick or made of a relatively rigid material. , Two or more. In the case where the perforation is made into two strips in this way, the interval is preferably about 3 to 10 mm.
[0008]
As described above, the slipper of the present invention is made of a thin and light material as a whole, in other words, a flexible material mainly made of synthetic resin. There is no such thing. However, since this perforation is intended to crease this part, it is not necessary to apply it with very fine eyes, rough eyes are sufficient, and as long as this purpose is reached, the center part of the bottom plate of the slipper is used. There is no need to completely cross the sewing machine. For example, if it is enough to make a crease depending on the material of the slipper, only the both ends of the center width part or only the center part of the width may be used. There is no problem.
Further, the sewing machine may be hung along the center in the longitudinal direction of the bottom plate, or may be provided so that the longitudinal direction of the bottom plate is divided into three.
[0009]
The slippers of the present invention are optimal as travel slippers. When the slipper of the present invention is overlapped as it is or when it is folded and overlapped, it overlaps flat, so that it can be accommodated in a bag in a compact manner.
What can be employ | adopted as said bag does not have a restriction | limiting in particular. A bag that matches the shape when the slippers are folded and stacked can be used. That is, when folded and overlapped, it can be stored compactly in one bag made of a transparent plastic film with a semicircular bottom.
[0010]
[Action]
Since the flat surface of the upper overlaps with the surface parallel to the bottom plate when stored, it can be stored compactly in a flat state. When using the stored slippers, the flat surface is flat without any folds or creases, so that it can be immediately restored during use to ensure a large and large mouth opening. When the upper is made of a relatively thin and lightweight material, this flat surface has a function of supporting the upper stably by lifting it loosely in an arc when in use. On the flat surface, you can wear a pattern or design nameplate, advertising mark, etc.
[0011]
The fold folds attached to the upper are preferably attached as box folds, with the peaks forming two sides of the flat side of the slipper's upper, and the flat folds are secured by firmly attaching the fold folds. The surface can be secured as stable. By applying sewing along the valleys of the folds and / or applying sewing along the two sides in the longitudinal direction, the flat surface can be secured more stably.
[0012]
The fold folds attached to the upper cover also firmly support the flat surface of the upper cover by firmly attaching the fold folds to ensure its stability.
The depth of the fold is gradually reduced toward the toe side. By gradually decreasing the depth of the fold fold toward the toe side, the edge on the cuff side of the flat surface forms the upper surface of the cuff opening, together with the cuff edge on the cuff side of the two fold folds A wide and large mouth opening can be secured.
[0013]
A perforation hung across the center in the longitudinal direction of the bottom plate can be easily folded at the perforation. The slipper can be folded into two vertically or three-fold with the upper side of the slipper outside, and can be stored compactly in a travel bag or the like. Also, when using a slipper that is folded in half or in three, the bottom plate portion immediately returns to its original flat state, and no creases remain as if it were folded and stored forcibly.
[0014]
As described above, the slipper of the present invention is folded in two vertically with the upper side of the slipper on the outside by the combination of the flat surface of the upper and the folding fold, and the perforation hung across the longitudinal center of the bottom plate. In the case of folding in three or three, the flat surface of the infinitely wide upper is overlapped with the surface parallel to the bottom plate while remaining flat and elastically supported by the folds. The slipper of the present invention has excellent foldability, so it can be easily and compactly accommodated in transparent packaging bags, etc., and it has excellent stability, ensuring a wide and large mouthpiece and a flat bottom plate during use. can do.
[0015]
【Example】
Next, an example explains the present invention. The present invention is not limited in any way by these examples.
[0016]
Example 1
FIG. 1 is a plan view of an embodiment of a slipper having a flat surface on the upper of the present invention, FIG. 2 is a bottom view thereof, and FIG. 3 is a left side view thereof. FIG. 4 is a rear view, and FIG. 5 is a front view thereof.
[0017]
As shown in the figure, this slipper basically comprises a bottom plate 1 and an upper 2 attached to the bottom plate 1. The upper 2 is made of a material in which a cloth is stuck on the front and back of a polyurethane foam sheet, and is made very lightly and softly. On the upper 2, a flat surface 3 is formed in which the two sides A ₁ and A ₂ in the longitudinal direction are parallel. The two sides A ₁ and A _{2 in the} longitudinal direction are each composed of a crest of folds 4 and perforated along the crest. Perforations are also applied along the valley of the folds 4.
[0018]
The bottom plate 1 is made of a material having a structure in which a bottom made of a flexible synthetic resin sheet is sandwiched between a foamed polyethylene resin sheet and an insole made of cloth, and is laminated, and is slightly different from a general-purpose slipper. Thin and light. The peripheral edge of the bottom plate 1 and the upper 2 and the edge of the upper side of the upper side are edged by attaching a bias tape with a sewing machine.
The depth of the fold fold 4 is gradually reduced toward the toe side. The edge of the flat surface 3 on the side of the mouth forms the upper surface of the mouth opening and secures a wide and large mouth opening together with the edge of the mouth side of the two folding folds 4 and 4.
In the vicinity of the center of the bottom plate 1, two coarse sewing hooks with thick count yarns are applied.
[0019]
The reason why the sewing machine hooks are set to two in this example is that a highly rigid foamed polyethylene resin sheet is used as the material of the core of the bottom plate 1 laminated between the bottom and the insole. By using two perforations in this way, it becomes possible to bend and bend easily even if a slightly rigid material is used for the bottom plate.
FIG. 6 is a view showing a state in which the slipper of FIG. 1 is bent so that the surface of the bottom bottom is aligned along the center sewing hook. When a pair of slippers are folded and overlapped in this way, they can be stored compactly in one bag (not shown).
[0020]
Example 2
FIG. 7 is a plan view of another embodiment of the slipper having a flat surface on the upper of the present invention, FIG. 8 is a bottom view thereof, and FIG. 9 is a left side view thereof. FIG. 10 is a rear view, and FIG. 11 is a front view thereof.
As in the first embodiment, it basically comprises a bottom plate 1 and an upper 2 attached to the bottom plate 1. The upper 2 is made of a material in which a cloth is stuck on the front and back of a polyurethane foam sheet, and is made very lightly and softly. The upper is a release-type upper where the toes are released, and a flat surface 3 in which two sides A ₁ and A _{2 in} the longitudinal direction are parallel is formed. The two sides A ₁ and A _{2 in the} longitudinal direction are each composed of a crest of folds 4 and perforated along the crest.
There are no perforations along the valley of the folds 4.
[0021]
The bottom plate 1 is made of a material having a laminated structure in which a bottom made of a flexible synthetic resin sheet and a cloth insole are laminated with a thin polyurethane foam sheet sandwiched therebetween, which is much more difficult than a general-purpose slipper. Thin and light. On the periphery of the bottom plate 1 and the upper 2, on the periphery of the toe portion of the upper cover, and on the edge on the mouth side, a bias tape is attached with a sewing machine to give an edge. The depth of the fold fold 4 is gradually reduced toward the toe side. The edge of the flat surface 3 on the side of the mouth forms the upper surface of the mouth opening and secures a wide and large mouth opening together with the edge of the mouth side of the two folding folds 4 and 4. In the vicinity of the center of the bottom plate 1, one coarse sewing hook with a thick count yarn is applied.
In this example, the sewing machine hook was made one instead of the highly rigid foamed polyethylene resin sheet of Example 1 as a material for the core of the bottom plate 1 laminated between the bottom and the insole. This is because a low thin polyurethane foam sheet was used.
[0022]
Comparative Example FIG. 12 is a plan view of a conventional travel slipper, and FIG. 13 is a rear view thereof. The bottom plate 1 and the upper 2 are made of relatively thin and lightweight materials so that they are not a burden to carry even a little. Especially, the upper 2 is lifted up in an arc when used. Because of inconvenience in storage, two folds or folds are often provided vertically so that the slipper can be folded in three in the longitudinal direction. However, after storing, especially after folding and storing, even if the bottom plate part can be immediately restored to its original flat state, the upper part is still crushed and the mouth opening is secured using hands You can't use it without it.
[0023]
