Description

[Detailed Description of the Invention] Technical Field The present invention relates to slippers, which are particularly suitable for long-distance trains, sightseeing buses, hospitals, etc., are comfortable to wear, do not stain the heel,
Furthermore, the present invention relates to simple slippers that are extremely inexpensive and can be recycled.

PRIOR ART In the past, many proposals have been made regarding simple slippers suitable for each of the above-mentioned uses, but conventional slippers of this type have problems in terms of comfort, resistance to soiling of socks, price,
It was not possible to satisfy all conditions such as productivity and post-processability. An example of the conventional example will be explained with reference to FIGS. 1 and 2. This slipper 1 is used in practical use, but the sole plate 2 is formed extremely elongated to fit the shape of the user's foot. In particular, the width of the heel rest 2a is narrow. Although cardboard is used as the core material 3, this is covered with a synthetic resin sheet 4, and the edges 4a of the sheet are heat-welded. The upper 5 is made of the same synthetic resin as the seat 4, and its central portion 5a is folded so that it can be unfolded during use.
b is heat-welded together with the edge i4a of the sheet 4 of the bottom plate 2.

According to such a conventional example, first of all, since the width of the heel rest part 2a is narrow, even when walking normally, and especially when relaxing on a train or the like and tilting the foot even slightly,
The drawback was that the heels would stick out quickly and the socks would get dirty. It is well known that there are very few people who keep their feet together properly when they are out of place on a train, etc., and many people have the habit of relaxing their legs and tilting their feet outward. As you can see, such flaws can be fatal for people who like cleanliness. 1. From a manufacturing standpoint, the bottom plate 2 of the conventional slipper was not designed with consideration given to walking during molding from cardboard material, so a considerable amount of core material 3 was wasted. This is unavoidable, and the end stop of the core material is poor, and the central part 5a of the upper 5
Since it is necessary to fold Vc at a predetermined angle and dimension, man-hours and mechanical equipment are required for this purpose.In addition, the edges 4a and 5b must be heat-welded, which requires a large amount of man-hours, electricity, and equipment costs. However, it had the drawbacks of being quite expensive and being a woman. Furthermore, when looking at the slipper 1 from the standpoint of post-processing, the thickness of the sheet 4 may be slightly thicker than that, since it is all made of synthetic resin, and there is a risk that toxic gas will be generated by combustion and cause pollution, for example. When a large amount of waste is released as waste from Japanese National Railways, etc., it becomes extremely difficult to dispose of it afterwards, and recycling is also impossible, so it is extremely uneconomical from the standpoint of resource conservation.

Purpose The cane of the present invention has been made to eliminate the drawbacks of the prior art described above, and its purpose is to have a bottom plate made of only thick paper such as corrugated paper, and to have a base plate with a foot rest. It has a shape that tapers from the constriction part provided after the insert part toward the heel, making the width of the heel rest considerably wider than the width of the user's foot. The purpose is to prevent the heel from protruding from the heel rest even when the foot is tilted while relaxing indoors, etc., and to prevent the socks from becoming dirty. Another purpose is that by forming the foot insertion part in a tapered shape that expands from the toe to the heel, it is easy to put the foot in regardless of the size of the foot, and the foot fits easily in the foot, and it also makes it easier to walk. Make sure that it does not easily come off inside.
The purpose is to make the shoes comfortable to wear. Yet another purpose, e.
The toes and heel are made to naturally bend slightly upward during use due to the reinforcement lines provided there, and this also prevents the toes and heel from getting caught on steps on the floor while walking. This is to prevent socks from getting dirty even if there is some moisture on the floor. Another purpose is to form muscle lines on both sides of the foot-insertion part, so that when the user lightly presses both edges of the foot-insertion part inward with one hand, the two O parts can be moved. When you stand up, the upper skin, which had been in a tense state until then, loosens and allows you to put your feet in. Also, when you stand up, the upper skin wraps around both sides of your feet, giving you a sense of security. At the same time, make sure that your socks do not become soiled with water, etc. Another purpose is to make the upper skin an extremely thin synthetic resin film that does not cause pollution even when burned, so that arbitrary information can be printed on the upper skin, and advertisements can be printed on the upper skin. In addition to increasing the product value by making it possible to use it for
Therefore, it is important to use K so that post-processing can be easily performed. Another purpose is to make the bottom plate only made of highly elastic and heat-retaining cardboard such as corrugated cardboard, which not only improves the feeling of use, but also makes it recyclable.
The goal is to contribute to resource conservation. 1. Another purpose is to set the inclination angles of the taper of the foot insertion part and the taper of the heel rest part to be the same, so that when a pair of sole plates are placed adjacent to each other in opposite directions, both sides completely interlock with each other. west,
To facilitate the punching process from a piece of cardboard material, to make it extremely productive, and to improve the yield of the material to the utmost limit.

Furthermore, another objective is to set the maximum width of the foot insertion capital to the total length of the bottom plate, the width of the muscle press + = j in the h' group, [the width of the toe part, and the minimum width of the foot insertion part 7 to each at a constant ratio. By setting the total length of the slipper, the dimensions of each part are immediately determined, and slippers of various lengths are configured into one similar shape, and slippers from children's to adult's 1 are all of their respective sizes. The goal is to make sure that it fits the feet best and is easy to wear. Another object is to simplify the installation of the upper by making it possible to simply apply the film upper under tension to a completely smooth sole, thereby reducing the cost of the slipper. The objective is to make it extremely inexpensive, and to enable ILI at a fraction of the cost of conventional products, for example.

Overview In short, the present invention comprises: a toe portion projecting forward; a foot insert portion tapered from the toe portion toward the heel at the same #4 diagonal angle on the left and right sides; and a maximum width portion of the foot insert portion. A bottom plate is formed of thick paper such as corrugated paper, and includes a constricted portion connected to the toe portion through an inclined portion and having approximately the same width as the toe portion, and a heel rest portion that tapers from the constricted portion toward the heel. At least, a reinforcement line is provided from a connection point between both sides of the toe part and the foot insertion part toward approximately the center of the inclined part, and a side edge of the foot insertion part is formed with the reinforcement line as a boundary. It is configured so that it can be folded upward, and a film-like upper is placed under tension on the upper surface of the foot insert, and its side edge is attached to the bottom of the foot insert, and the entire length of the sole plate is l. , the maximum width of the foot insertion part is B1, and the width between the reinforcement lines in the inclined part is t-B2. The width of the toe portion is B3. The present invention is characterized in that, when the minimum width of the foot insertion portion is B4, the following is satisfied: B2 key t B3+-1 B4 -1+10"r"'.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained below based on embodiments shown in the drawings. Third
In FIGS. 7 to 7, the slipper 1 according to the present invention is
The sole plate 12 is formed of a thick paper 13 such as corrugated paper, and a very thin film JN-shaped upper skin 1 is placed on the upper surface of the foot insert 14 of the sole plate.
5 in a tensioned state, and its side edge 15a is adhered to the lower surface i4a of the foot insert. The sole plate 12 includes a toe part 6 that protrudes forward, a foot insert part 14 that expands in a square shape from the toe part toward the heel at the same inclination angle A on the left and right sides, and a maximum width of the foot part. The part 14bK is connected via a steep slope m17, and has a constriction part 18 having approximately the same width as the toe part 16, and a constriction part 18 that tapers from the constriction part toward the heel at the same inclination angle A as the foot insertion part 14. It consists of an open heel rest part 19 and a heel part 20 that projects rearward from the heel rest part 19, and in the illustrated embodiment, corrugated paper is used. Also, both sides 16a of the toe portion 16
A reinforcing line 22 is provided which is recessed downward from the connection point 21 of the foot insertion part 14 toward the approximate center of the inclined part 17, and the 11118 part 14c of the foot insertion part 4 is separated from the reinforcement line as a boundary. The boundary between the toe part 16 and the foot insertion part 14 and the heel rest part 19 and the heel part 20 are configured so that they can be bent upward.
Recessed lines 23 and 24 are also provided at the boundaries between the toe portion 16 and the heel portion 20, respectively.

52.5 35 45 Function The present invention 8A is constructed as described above, and its function will be explained below. First, referring to FIG. 8, we will explain how to make a mold from the material 26 of the sole plate 12 of the slipper 11 according to the present invention. Since the angles A are the same, if the pair of bottom plates 12 are placed adjacent to each other in opposite directions,
They overlap completely, with no gaps on either side. Therefore, by alternately drawing the shapes of the bottom plate 12 in opposite directions on the material 26 and forming them in two stages, the bottom plate 12
The material 26 that will become No. 2 will be punched out with good accuracy. Here, the part where the material is wasted is the intermediate gap 26a.
and a blank space 26b, the walking distance of the material 26 is increased to the maximum, the bottom plate 12 can be manufactured extremely efficiently, and the cost is greatly reduced. Note that in reality, by manufacturing a press mold having a blade having the same shape as the contour line 26c of the bottom plate 12 on the material 26, the bottom plate 12 is formed on the material 2.
It can be mass-produced from 6 onwards.

Further, each of the reinforcement lines 22, 23, and 24 is also stamped and completed at the same time as the bottom plate 12 is punched out.

Then, an upper skin 14 such as a polyethylene film is affixed under tension to the foot opening 4 using an appropriate automatic machine. In this case, since there is no need to make the upper 14 loose, the attachment process is very easy and productivity is high. In addition, before attaching the upper 14, the company name, product name, etc. of the provider of the slippers 11, etc.
You can also print advertisements such as catchphrases, product pictures, etc., so it is very useful for promoting information.

The completed slippers 11 will be shipped one pair at a time with their bottom surfaces stacked on top of each other, but since the upper 14 is thin, the thickness of the slippers 11 is almost equal to that of the sole plate 12.
In other words, since there is only one sheet of cardboard paper, it is not bulky when transporting food, has good transport efficiency, and is inexpensive to transport.

Next, the operation of the slipper 11 in use will be explained with reference to FIGS. 3 to 7. Since the slippers 11 are sold in units of one foot with the bottom surface squared by ±1, the user who has purchased the slippers presses both sides of the foot opening 14 inward with the fingers of one hand. Then, both side edges 14c are bent from the reinforcement line 22 and stand up as shown by imaginary lines in FIG. This loosens the upper to an appropriate degree and completes the foot opening 14 as shown in FIG. The user has to wear the slippers 11, but since the foot opening 14 has an appropriate taper, they are easy to put on and do not slip out while walking.
Furthermore, the same slippers 11 can be used by both adults and children. When the user walks a little, the toe section 16 naturally bends slightly upward from the muscle line 23 and the heel section 20 slightly upward from the muscle line 24 due to the vertical movement of the ankle. The socks do not get caught on steps on the floor, increasing safety, and the socks do not get dirty even if there is some moisture on the floor. Furthermore, the rising edge K of the edge 14C allows the feet to be wrapped from the left and right sides, which increases the sense of security and provides a good feeling of use.

Further, the heel rest part 19 is expanded from the waist part 18 toward the heel and is considerably wide, so even if the user relaxes and tilts both feet, the heels of the feet do not protrude, so the socks are not soiled.

In addition, the widths Bl, B2 of each part of the slipper 11. B3 and B4
Since is set at a constant ratio to the total length t, it is easy to manufacture pickpockets and pads of various sizes, and since they are all approximately similar to each other, they can be used for everything from small to adult use. Slippers 11 can be easily manufactured. Note that the ratio determined in the present invention was determined as the best as a result of many experimental studies, and by setting this ratio, slippers of any size will be comfortable to wear. ,
It won't get wet during use.

His slippers 11 can be collected and burned in a garbage incinerator, and they do not cause any pollution.
Must'j! ! Since it is possible to recycle them depending on the situation, for example, in Japanese National Railways, etc., the used slippers 11 that are thrown away in large quantities have a cash value, help to secure some financial resources, and at least there is no problem with post-processing.

In the illustrated embodiment, the heel rest part 1 of the slipper 11 is
Although the upper surface of 9 has been described as being flat, if necessary, reinforcement lines (not shown) can be provided upward from the lower surface to prevent slipping by forming a plurality of convex portions on the upper surface. Alternatively, liquid synthetic resin can be applied in several lines and dried to prevent slipping.

In addition, what is shown in FIG. 9 is a pick-up according to another embodiment of the present invention. and muscle push @24 (third cause) was abolished, and the heel rest part 19
The circumference is formed into an arc shape. Since the other parts are the same as those shown in FIGS. 3 to 7, the same parts are given the same reference numerals on the mouth surface, and the explanation will be omitted.

Further, the operation of the slipper 110 of this embodiment is similar to that of the previous embodiment, so a description of the operation will be omitted.

Effects Since the present invention is constructed and operates as described above, the sole plate is constructed of thick paper such as corrugated paper, and the heel rest is arranged from the constricted part provided after the foot insertion part toward the heel. Because it has a widened shape, the width of the heel rest can be made considerably wider than the width of the user's foot. Make sure that the heel does not protrude from the heel rest.
As a result, the excellent effect that the socks do not get dirty can be obtained. In addition, the foot opening is tapered from the toe to the heel, so regardless of the size of your foot, it's easy to put your foot in, and the heel fits your foot easily, and it doesn't slip out while walking. This has the effect of making the company feel more comfortable. Furthermore, the toes and heel are designed to naturally bend upwards slightly during use due to the reinforcement lines provided there, so the toe and heel do not get caught on steps on the floor while walking. It's not a waste, and it has the effect of not getting your socks dirty even if there is some moisture on the floor. In addition, since there are lines formed on both sides of the foot-in part, when the user lightly presses both edges of the foot-in part inward with one hand, the two edges rise up and remain in a tensioned state. The upper skin loosens, allowing ample space for your feet to fit in, and the raised edges wrap around both sides of your feet, giving you a sense of security and preventing your socks from getting dirty due to water, etc. An effect can be obtained that can prevent this from occurring.

Furthermore, since the carapace is made of an extremely thin synthetic resin film that does not cause pollution even when burned, any information can be printed on the carapace, and it can also be used for advertisements, etc. It has the effect of increasing the commercial value, causing no pollution even if it is burned together with the bottom plate, and making post-treatment easier. In addition, since the bottom plate is made only of cardboard, which is highly elastic and has good heat retention, it is comfortable to use, does not feel bulky, and is recyclable, which contributes to resource conservation. be. In addition, since the inclination angles of the taper of the foot insert part and the taper of the heel part are set to be the same, when a pair of bottom plates are placed adjacent to each other in opposite directions, both sides completely interlock with each other. It has the effect of making the punching process of the material easier and extremely productive, and also improving the walking distance υ of the material to its maximum. Furthermore, the maximum width of the foot-in part, the width between the reinforcement lines in the slope part, the width of the toe part, and the minimum width of the foot-in part are each set at a constant ratio to the total length of the bottom plate.
By determining the total length of the slipper, the dimensions of each part are immediately determined, and slippers of various lengths are constructed to have approximately similar shapes.
The effect is obtained that slippers for all sizes from children to adults can best fit the feet of each size and are easy to fit. In addition, since the film-like upper can simply be attached under tension to a completely smooth sole, the attachment of the upper can be facilitated, and this makes the cost of the slippers very low. For example, the excellent effect of manufacturing at a fraction of the cost of conventional products can be obtained.
