Description

  The present invention relates to indoor shoes to be worn when moving indoors such as entrances, corridors, kitchens, living rooms, etc., for example, for use on floors of flooring, especially without a string or fastener for tightening feet and legs. The present invention relates to an open-type slipper with no heel.

  2. Description of the Related Art Conventional slippers for general indoor shoes are roughly divided into two types, a hanging type and an outer sewing type. The former suspension type is a shape in which a seam for joining the instep portion of the person wearing the slipper and the bottom portion of the sole is inside and cannot be seen from the outside. In this suspension type, a mold having a size of the upper part, which is the upper part, is required at the time of manufacturing, and therefore, it is not assumed that there is no mold corresponding to the size of the upper part. Hanging type slippers have been widely used in public places such as hospitals, gymnasiums, and public halls. Most of them are hard types made of leather or vinyl. Each time you walk, the heels rise, the soles separate from the slippers, and they make a rattling sound, so the hanging vinyl hard type slippers have a poor luxury and the heels are separated. Because it was worn, it was harder to walk than shoes.

  On the other hand, a seam that joins the instep portion and the sole portion of the sole on the outside and is visible from the outside is called an outer stitch type. This type does not require a size mold when it is made, and therefore has a free size, and is easy to pursue design. The toes are made with a generous amount of comfort, and they are often used as indoor shoes for ordinary households. However, the seam has come out and the outer periphery is conspicuous, so that the finish is not finished in a neat appearance, and the width is increased by the width of the border.

  Also, in recent years, soft-type indoor slippers have appeared as slippers aimed at comfortableness as compared with conventional hard-type slippers. These soft-type slippers are generally a type of hanging type.After arranging the outer surface of the upper on the inner side and hanging it on the bottom with the bottom bottom facing upward, the entire slipper is turned upside down. In many cases, the outer surface of the upper is turned outward, and then the core material of the midsole is inserted into the gap between the upper and lower soles to finish it (for example, see Patent Documents 1 and 2). And the skin contact is finished softly as a whole, for example, using a soft cloth for the upper part and the upper bottom. Attempts have been made to improve comfort by, for example, increasing the size of the upper fabric to the sole of the shoe and using a low-resilience resin for the midsole.

  These soft-type indoor shoes are designed for comfort, and are more likely to be used by the occupants on a daily basis, rather than visitor slippers or durable slippers. It is suitable. And there is a soft type in which the foot area is deepened by increasing the fabric area of the upper part. For example, the instep is suspended not only on the toes but also in a deep cutting so that the instep covers not less than one-half to two-thirds of the entire slipper. May be. By adopting such a shape that the foot is deeply inserted, it is possible to minimize the lifting of the heel and enhance the hold feeling. Nevertheless, since they are slippers and their heels are open, it is inevitable that the heels will float when walking, and the hold feeling is insufficient.

JP 2005-177407 A JP-A-11-009307

  Slippers are footwear that is worn by putting a toe between the upper part and the front of the upper sole and hooking them, so that the heel and the rear of the upper sole are separated during walking. Therefore, when walking with slippers, the slippers usually cannot follow the movements of the feet, and the heels tend to float from the slippers, resulting in fluttering motions such as fluffy and fluttering.

  Like the soft type slippers, the heels are thicker than the hard type and comfortable to wear, and the heel is open even if the slipper has a relatively high hold feeling, such as a large covering of the instep and a covered fabric. It is easy to take off and the size is about 3 to 4 kinds such as L, M, S, etc. It is less versatile than shoes, so it is difficult to fit. It was undeniable that the flapping feeling remained. There is a demand for a slipper that is more comfortable to wear and has a higher fit to the foot than conventional soft type slippers. In addition, soft-type slippers do not have the luxury of being suitable for visitors, and tend to have a cheap feeling in practical use.

  In addition, slippers are worn by inserting the toes between the instep and the upper sole and hooking them on.The height of the instep, the width of the foot, and the size of the first foot vary greatly from person to person. ing. Therefore, it is usually necessary to reduce the size in order to fit each individual's feet, but when assuming a realistic sales lineup, as a result of multiplication of different sizes × different patterns, very small quantities and many kinds There is a limit because of this, and it is practically impossible to arrange a large number of size differences, and at present, it is possible to provide only rough things such as S, M, and L.

  However, when worn by people with intermediate foot sizes between these jumps, they do not fit originally, and because of the open type, the heel and the upper back of the slipper separate from each other, and it is easy to become shiny and easy It was difficult to say that it was easy to take off and was not stable when walking, and it was not sufficient in terms of safety, as it was easy to fall if it ran.

  Therefore, the problem of the slippers to be solved by the present invention is that the fabric of the upper sole and the instep is soft, the skin contact is good, the bare feet are warm and comfortable, and the excessive tightening is performed by a moderate fit from the toes to the instep. An object of the present invention is to provide a slipper having a structure that is easy to walk without being uncomfortable, difficult to take off, and has a high versatility even if the size lineup is jumpy and can be applied to a person whose foot size varies.

  In addition, in addition to being difficult to lift up and take off so that the heel separates greatly from the upper sole heel, it is a slipper with a high fit that is difficult to take off even if people with multiple foot sizes wear it, Another object of the present invention is to provide a slipper that has a good touch to bare feet, has excellent comfort, and is luxurious.

According to a first aspect of the present invention, there is provided a slipper comprising a top and a bottom, wherein the top is provided with a filler inserted between an outer surface and an inner surface. The outer surface and the inner surface are sewn in the width direction of the slipper so as to divide the front part of the upper part from the front toe side to the rear part upper part into a plurality of steps, and a plurality of quilted step parts Wherein the outer and inner surfaces of the upper part and the upper surface of the bottom part are in a raised state in which fibers of hair feet of 7 mm or more are densely arranged, and are in a raised state. Is a slipper having a plurality of quilt-shaped steps and a raised surface, the directions of which are aligned so that the tips can be inclined toward the toe side.
In addition, the bottom may be a thick bottom having an elastic body therein.

  In the second means, the plurality of quilt-shaped steps are different in the amount and thickness of the filling material in each step, so that the pressing force on the inner surface of each step is different. A slipper according to the first means, characterized in that:

  In the third means, the plurality of quilt-shaped steps are different in the amount of filling and the thickness of the filler in each step, so that the pressing force on the inner surface of each step is different. A slipper according to the first or second means, characterized in that:

  Since the slipper of the present invention is brushed in a bore shape, but is formed in a quilt-like step portion, a three-dimensional expression is formed on the outer surface of the instep by the swelling of the filling material, and it is beautiful. It has an aesthetic appearance. In addition, since the bore-like brushing gives the wearer a gentle and comfortable feel to the skin, it is unlikely to cause discomfort during long-term use. Furthermore, since the inner surface of the instep and the raised brush on the bottom upper surface are aligned in the direction that the tip is easy to fall down on the toe side, insert the foot between the instep and the upper bottom. When going, while the foot tip slips inward along the order of the tip of the hair, the movement in the opposite direction is opposite to the tip of the hair, so in the direction in which the foot comes off Friction is applied, making it difficult to remove.

  In addition, since the quilt-shaped steps are formed in multiple steps, the instep of the foot is appropriately pressed by the batting of the filler, so the gap between the instep of the slipper and the foot is appropriately closed. , Not only is it difficult for the warm air around the internal bore to escape, but also because the periphery of the upper is difficult to lift, the heel of the slipper is hard to separate from the sole, the heel of the slipper easily follows the movement of the foot, the heel of the slipper The part is separated from the sole of the foot and it is difficult for it to be shiny and easy to walk.

  Also, the quilt-shaped step and the raised brush make it difficult to remove, so even if someone with a slightly different foot size wears it, the difference in size should make it easier to remove it. Can be absorbed, and can be worn without being easily detached. Therefore, the applicable width of the foot size that can be worn for each slipper of a specific size can be widened, and a slipper of a more general-purpose size can be obtained. Further, by utilizing the versatility, the number of variations of the lineup provided for different sizes can be further reduced, so that the number of practical products can be reduced, and the manufacturing cost can be greatly reduced.

  If the inside diameter and the pressing force are different for each step of the quilt part of the instep, a part that fits easily depending on the size of the inserted toe, and it is easy for one person to wear one slipper Can be secured in a wider application size range. This is because a portion that can be held can be easily obtained because the pressing force is different for each of the plurality of steps even though the contact condition is soft.

  In addition, by increasing the pressing force of the quilt portion of the instep portion, the tightening of the instep portion can be slightly strengthened even with a soft hit. Therefore, while the toes are in a relaxed state, the ability to follow the feet can be ensured by the tightening of the instep when walking, so that the slippers can be made easy to walk.

FIG. 4 is a cross-sectional view illustrating one embodiment of an example. FIG. 1 is a perspective view illustrating one embodiment of an embodiment.

Embodiments of the present invention will be described below with reference to the drawings.
The slipper (1) of the present invention shown in FIGS. 1 and 2 has a substantially elliptical (straw-shaped) bottom (3) and an upper part about two-thirds above the bottom (3) from the toe side. (2) is a slipper having a shape to cover. Since the left and right slippers (1) are worn as a pair, the left foot and the right foot have a symmetrical shape. The outer surface (4) and inner surface (5) of the upper part (2) and the upper surface (17) of the bottom part (3) are made of warp knitted pile fabric (basis weight: 490 g / m ² ). The bristle feet are raised with, for example, a very fine fiber having a length of about 14 mm, and the surface thereof is a raised portion (10) covered with a dense raised fiber in a bore shape. The length of the bristle feet is not limited to 14 mm in the embodiment, but can be applied if it is 5 mm or more, preferably 7 mm or more.

  By the way, in the brushed fabric, the tip of the raised portion of the pile tends to be inclined in general, and when the hand is slid to the surface in accordance with the flow of the hair, the one that flows smoothly is turned on. Hair), and the case where it gets caught on the hand, is called a barb (reverse hair). Then, as shown in FIG. 1, in the slipper (1) of the present invention, when the foot is inserted into the slipper (1) and worn, the direction of the hairy foot (11) is directed toward the toe, so to speak. The hairs are arranged so that the feet slide smoothly into the slippers so that the insertion direction is smooth, and on the other hand, when pulling out the feet, the fabric becomes the reverse direction and it is difficult to take off I have. The brushed pile fabric is arranged in the same direction (11) as the bristle feet, and is oriented so that the bristle tips fall from the heel side to the toes.

  Then, by arranging the fabrics in order of the order of the hairs (arranged hairs), when the fibers are rubbed and stroked by hand from the heel side to the toe, they slide smoothly, so the upper surface of the bottom part (17) Both the outer surface (4) and the inner surface (5) of the instep have hair tips flowing toward the toes. Therefore, when putting on, while the foot enters smoothly, the direction in which the foot is to be taken off is reverse, so that the tip of the hair becomes upright and friction occurs, so that it is difficult to take off.

  Various materials such as synthetic fibers such as acrylic, polyester, and rayon, blended fibers thereof, natural fibers such as wool, animal hair, and cotton, and blended fibers of natural fibers or chemical fibers are used as such raised fibers. It can be used for pile yarn after raising it in a shape. The raised hair tips (12) are obtained, for example, by pressing a cylindrical roll having a large number of needles against the surface of the raising machine and pulling out the raised fibers in one direction when the base fabric is a woven fabric. Can be. When the base fabric is a knitted fabric, a cut pile in which pile yarns are knitted or the upper part of a looped pile is cut from a pile-woven knitted fabric and the fluff is made long can also be suitably used. As described above, any fabric can be applied to either the pile woven fabric or the pile knitted fabric, as long as the fabric is arranged so as to be in order from the heel side to the toe side.

  The upper part (2) has a batting (13) enclosed between the outer surface (4) and the inner surface (5) fabric, and is shown in the figure as a three-stage quilted fabric. Quilting with filling batting (13) from the toe (6) at the tip to the instep (7) at the back by stabbing from the surface (4) to the inner surface (5) Three step portions (8) are formed. Filling is distributed evenly on the upper. Since the instep becomes wider and higher from the toe toward the instep (7), the pressing feeling of the filled batting can be changed between the toe and the instep. Further, if necessary, the amount of batting may be weighted according to the position of the upper, or the width of the three steps may be biased step by step, so that the feeling of pressing on the foot by the batting can be adjusted.

  The filling material (13) of the filler is not limited to cotton and polyester as long as it can be used for the bulging of quilting, and various materials can be used as the filler regardless of chemical fibers or natural fibers. In the present embodiment, for example, a case using polyester will be described below.

  That is, the bulging of the filler material inserted between the outer surface (4) and the inner surface (5) of the upper part (2) gently holds the foot inserted into the slipper so as to wrap it in its entirety. The purpose is. Therefore, since it is sufficient that the pressing force can be applied so that the slippers can be taken off or the heel does not float softly, the batting material is not particularly limited, and is used for general batting. If it is a material, it can be widely applied.

In the present invention, since the whole is held not by local point contact but by surface contact, the overall frictional force and the pressing force are taken into account and the toe is held in the slipper moderately. Become.
Therefore, the batting does not need to press the foot tightly, and the toes are not tightened. And, even with a soft light pressing force, it is possible to hold the entire surface sufficiently, so that the wearer can use it comfortably without feeling oppressed, and in winter the bore The feet are warm due to the surrounding air layer. In addition, the bottom of the slipper also moves to follow this when the heel rises during walking due to the overall holdability, so it is difficult to float and it is easy to walk, and the direction of the bristle flows to the toe side Because of the high friction in the direction against the fur, it is difficult for the feet to come off the slippers.

  In the slipper of the present invention, the toe side of the bottom (3) is further curved so that the tip of the toe is slightly curved upward when the slipper is viewed from the side so that the tip does not catch on the floor. By using the slippers, it is possible to make the foot easy to walk without catching the toes. In addition, the base (16) is made of a rough non-slip material such as suede-like leather or artificial leather, so that it is hard to slip even on a smooth floor such as a flooring and is easy to walk. You can also. The bottom part (3) is a core material of an elastic body (15) having a thickness of, for example, about 15 mm to 25 mm between the bore-raised cloth on the top surface (17) and the bottom surface of the suede-like cloth on the bottom surface (16). Insert (18). In addition, the core material of the heel part can be made slightly thicker, and the core material (18) is formed by appropriately laminating one or more types from urethane resin, high foaming EVA resin, high elasticity EVA resin, EVA resin, and the like. Can be used. Further, a non-slip (19) may be further attached to the bottom surface of the heel.

  The slipper (1) of the present invention can be manufactured, for example, as follows. First, the space between the raised fabric on the outer surface 4 which is the upper plane of the upper part (2) and the raised material on the inner surface (5) of the upper part (2) is filled with the batting (13). The upper part (2) is sewn up and down like a seam shown as a sewn sewing part (9) in the drawing and sewn like quilting. Then, the upper part is placed outside the upper part (2) with the inner surface (5) facing upward, the outer surface (4) facing downward, and the bottom material (16) of the bottom part (3) facing upward. After facing the surface (4) and disposing the upper surface (17) of the bottom (3) downward, the outer periphery of the upper part (2) is sewn to the bottom (3) with a sewing machine. The upper flat surface (17) and the bottom surface (16) of the bottom portion (3) are not sewn toe portions. Next, after inserting the core material (18) from the toe side between the cloth on the upper surface (17) and the bottom surface (16), the upper part (2) and the bottom part (3) are turned over, and the upper part (2) is turned over. ), The outer surface (4) is on top, the inner surface (5) is on, the upper surface (17) on the bottom (3) is on top, and the bottom surface (16) is on lower side. obtain.

(Comparative test on the difficulty of taking off when using slippers with feet)
The product of the present invention is used for friction by brushing, especially friction in a direction opposite to the direction of the brush tip (11), and pressing (14) by bulging of quilting of the quilted step (8). Sometimes the foot is hard to come off and it is easy to follow the movement of the foot. Therefore, regarding the difficulty of taking off when using the product of the present invention, a "test for difficulty in removing slippers using footprints" was conducted at the Meriken Quality Inspection Association Hyogo Test Center, and slippers of other shapes were carried out. And the difference of the difficulty of taking off was compared.

  In the test, the foot model of the right foot of bare feet was attached to the slipper, and the tip of the slipper was clipped to a tensile tester (AGS-X5KN manufactured by Shimadzu Corporation) and pulled. The tensile strength A method of JIS L1096 was applied mutatis mutandis. Is a record of the resistance when the player comes off the last. The pulling speed is 200 mm / min. The last was inserted deeply into a slipper serving as a measurement sample, and the tip was clipped while appropriately using a double-sided tape. The string attached to the clip was clamped by the chuck of the tensile tester, and the footprint was fixed by hand while taking care that the slipper was pulled vertically. In addition, since the value of the resistance of the slipper is small, the effect on the test by fixing the footprint by hand can be ignored.

  The following table shows the values obtained by rounding the average of three measurements to one decimal place. Slippers of the present invention (slippers described in the examples, which have three quilt-shaped steps, a bore of 14 mm in bristles, and a tip inclined to the toe side), an outer winding type slipper, a soft type slipper, For the five types of the hanging type slipper and the fore-open soft type slipper with an open toe, a slipper having a size corresponding to a footprint size of 23.5 cm was used as a sample.

  As shown in Table 1, the product of the present invention had a tensile strength of 9.2 N required to come off. On the other hand, the tensile strength of the conventional slipper was 2.0N to 5.5N. In comparison with the results of these comparative tests, it was confirmed that the product of the present invention had a high tensile strength, and the foot was much less likely to come off from the slipper in a walking movement. On the other hand, it is not that the value is not too high, so it is not that you can not take off just because it is difficult to take off when walking, and you can take off enough if you follow your hands when finishing normal wear It is a degree of tightening. Despite being a slipper with no band on the heel, it is difficult to take off firmly, so it has good followability to foot movements and it is easy to walk.

  Further, according to the product of the present invention, since the upper shell filled with the batting of the polyester cotton has three steps, and the quilting of the step part (8) from the toe to the upper in the direction of the pressing direction (14) is properly tightened. Although there is no unpleasant pain, the shape of the hair is good and it is difficult to take off due to the frictional resistance due to the direction of the hair foot (11). Because it has a characteristic that it is much harder to remove than other conventional products, there is room for securing a wide range of wearers regardless of shoe size by further adjusting the degree of tightening of the step (8) in advance. You can see that there is.

  Such tightening can be adjusted by the filling amount of the batting. For example, increasing the amount of batting in the instep position (7) increases the pressing force in the instep portion (7), so that it can be softly tightened in combination with the brushing of the bore (10). It can be held so that it does not fall off. Even if the tightening of the toes is loose, it can be worn. Then, even if the size of the last of the wearer is slightly different, it is possible to provide a margin to cope with it. Since it can be held firmly at the position of the instep (7), it is possible to absorb differences in the toes. Therefore, it is safe to use three types of slippers, S, M, L, even if you provide them in free size, even if a small foot size person wears them, they do not come off. It will be possible to walk. Therefore, with the slipper of the present invention, there is sufficient room for expanding the range of size application.

  Certainly, it is different from ordinary outer shoes that it has a large number of sizes, and although it is general that the size of slippers for indoor shoes is about 3 to 4 types, the slippers still have different colors, patterns Since there are differences, the variations including these are substantially large, and if these are actually prepared as a product lineup, it is likely that many kinds of products will be produced. According to the product of the present invention, a size such as SML can be stocked as before, but there is room for providing a free size, so that a more flexible production system can be taken. Slippers that can be easily commercialized can be obtained.
