Description

  The present invention relates to a shoe slip prevention tool.

  When wearing new shoes, shoe slippage may occur mainly in the vicinity of the heel of the foot or the Achilles tendon. If a shoe slip occurs, it can be severely painful and walking difficult. This shoe slip is caused by friction between the rear portion of the foot heel and the inner surface of the shoe heel during walking. In order to prevent such shoe slippage, a shoe slippage prevention tool that reduces friction between the heel and the inner surface of the shoe has been proposed.

  For example, Japanese Patent Application Laid-Open No. 2002-369836 discloses a contact material for preventing shoe rubbing. This pad is attached to the heel of the user's foot. The pad material includes a pad material main body and a sliding piece. The contact material main body and the sliding piece are fixed to each other. The main part of the patch is stuck on the heel of the user's foot. The sliding piece is interposed between the main body of the contact material and the inner surface of the heel of the shoe.

  The pad material main body has a pad. A sliding piece consists of a film formed in the flat ring shape (loop shape). This film has lubricity and flexibility.

  In use, this pad is attached to the heel of the foot such that the loop of the sliding piece is in the vertical direction. Then, when the user walks, the sliding piece moves as if the caterpillar repeats forward and backward movement, and the sliding pieces having sliding properties rub against each other, so that it is substantially in a state of cutting off against friction. .

  The shoe rubbing prevention patch disclosed in the above publication may be peeled off from the heel while the user is walking. When this brazing material is peeled off from the heel, there is a high possibility that the expected action cannot be achieved. In addition, when the user takes a bath, it is difficult to use the attached adhesive material again. In addition, there is no guarantee that the film constituting the sliding piece will move in the same manner as the forward and backward movement of the caterpillar.

FIG. 4A is a cross-sectional view showing another shoe slip prevention device, FIG. 4B is a cross-sectional view showing still another shoe slip prevention device, and FIG. 4C is still another shoe slip prevention device. It is sectional drawing which shows a prevention tool.

  Hereinafter, the present invention will be described in detail based on preferred embodiments with appropriate reference to the drawings.

  FIG. 1 shows a shoe slip prevention tool 2 according to an embodiment of the present invention. Here, the up and down direction in FIG. 1 is referred to as the up and down direction or the vertical direction of the shoe slip prevention tool 2, and the left and right direction in FIG.

  The shoe slip prevention tool 2 includes a first bag body 4, a second bag body 6, a support plate 8, and a cushion material 10. The second bag body 6 is housed inside the first bag body 4. Accordingly, the first bag body 4 is also referred to as the outer bag body 4. The second bag body 6 is also referred to as the inner bag body 6. The support plate 8 is housed inside the inner bag body 6. The support plate 8 has an effect of preventing the shape and posture of the shoe slip prevention tool 2 from changing greatly. The support plate 8 can exert a cushioning action on the user's foot. The support plate 8 can also have an effect of guiding the relative vertical movement of the user's foot with respect to the shoe. In this embodiment, when both the outer bag body 4 and the inner bag body 6 are deaerated and made flat, they have a rectangular shape. The support plate 8 and the cushion material 10 are also rectangular. However, these 4, 6, 8, and 10 are not limited to such shapes. For example, it can be modified to match the shape of the shoe used.

  Both the outer bag body 4 and the inner bag body 6 are formed of at least one of a synthetic resin film, a woven fabric, and a nonwoven fabric. In the case of a synthetic resin film, the physical properties are preferably set such that the tensile strength is 20 MPa to 240 MPa, the tensile elongation is 5% to 700%, and the Young's modulus is 200 MPa to 4000 MPa. The measuring method of tensile strength and tensile elongation conforms to JIS C2151, and the measuring method of Young's modulus conforms to ASTM D882. As the material of the synthetic resin film and the nonwoven fabric, typically, polyethylene, polypropylene, polyester, nylon, and the like, and a mixture of at least two of these can be employed. In the case of a woven fabric, as a material thereof, recycled fiber made of copper ammonia rayon, viscose rayon, etc., synthetic fiber made of nylon, acrylic, polyester, etc., natural fiber made of silk, wool, etc. can be adopted. The thickness of the material of these bags 4 and 6 is preferably selected from the range of 0.006 mm to 0.6 mm. Even when the bag bodies 4 and 6 are formed of a woven fabric or a non-woven fabric, the coefficient of friction is small. In the case of a synthetic resin film, the friction coefficient is further reduced. The bag bodies 4 and 6 have lubricity and softness (flexibility). The synthetic resin film bags 4 and 6 are further excellent in lubricity and flexibility. When the bag bodies 4 and 6 rub against each other, the friction is very small. In the case of a synthetic resin film, it is preferably transparent. This is because the state of the members inside the bag bodies 4 and 6 can be easily confirmed visually.

  The outer bag 4 is preferably sealed with respect to the outside after an appropriate amount of air is injected. That is, it is preferable that the outer bag body 4 has no vent hole. From this viewpoint, the outer bag body 4 is preferably formed from a synthetic resin film. If an appropriate amount of air is sealed inside the outer bag body 4, the support plate 8 accommodated in the inner bag body 6 can easily move. The inner and outer bag bodies 4 and 6 are easily slipped, and friction is further reduced. The inner bag 6 may be formed in a sealed state, or may be formed so as to allow ventilation.

  In the present embodiment, cardboard paper is used as the support plate 8. Corrugated paper has moderate elasticity. The corrugated cardboard has an appropriate rigidity enough to maintain the shape and posture of the shoe slip prevention tool 2. The shoe slip prevention tool 2 is easy to handle with a shoehorn. It is preferable that the corrugated paper is in a posture in which the step portion 18 forming the elongated hollow portion extends in the vertical direction inside the inner bag body 6. This is because, when the user's foot moves up and down with respect to the shoe, the step portion 18 can smoothly guide the vertical movement of the foot without causing resistance. Corrugated paper is preferable as the support plate 8, but other materials having moderate elasticity and rigidity can be selected.

  The outer bag body 4 is divided into two upper and lower spaces by a crimping portion 12 extending linearly in the lateral direction. The inner bag body 6 in which the support plate 8 is accommodated is accommodated in the large first space 14 below. The cushion material 10 is accommodated in the small second space 16. The first space 14 is also referred to as a lower space 14, and the second space 16 is also referred to as an upper space 16. The lower space 14 has such a size that the support plate 8 accommodated in the inner bag body 6 can freely move. In particular, it is preferable that there is a movable space (play) of about 5 mm to 20 mm for the support plate 8 in the vertical direction. The crimping part 12 may be an intermittent line or a continuous line. In other words, when the outer bag body 4 is made of a synthetic resin film, the crimping portion 12 may or may not have a ventilation portion. That is, the lower space 14 and the upper space 16 may or may not be permeable to each other. Instead of forming the crimping portion 12, the width of the outer bag body 4 between the insertion position of the cushion material 10 and the insertion position of the support plate 8 may be narrower than the length of the cushion material 10. That is, a constriction in which the cushion material is difficult to pass may be formed in the outer bag body 4.

  The cushion material 10 has a strip shape that is long in the lateral direction. When the shoe slip prevention tool 2 is attached to a shoe, the cushion material 10 is required to be positioned along the upper edge of the heel of the shoe. This is to improve the shoe slip prevention effect. The cushion material 10 is flexible. As this cushioning material 10, a cushioning material formed from cotton, non-woven fabric, sponge, general-purpose synthetic resin (polyethylene, polypropylene, etc.) can be employed. The cushion material 10 is accommodated in the upper space 16 without any packaging, but is not limited to this configuration. The cushion material 10 may be stored in the upper space 16 after being stored in another bag formed of a synthetic resin film or the like. Further, the cushion material 10 may be fixed in the upper space 16.

  FIG. 2 shows a procedure for mounting the shoe slip prevention tool 2 on the inside of the shoe 20. The attachment shown in FIG. 2 does not fix the shoe slip prevention tool 2 to the shoe 20 by bonding or locking. As used herein, the term “wearing” refers to being held between the rear end surface of the user's foot heel 22 and the inner surface of the heel of the shoe 20 as shown in FIG. The shoe slip prevention tool 2 is not fixed to the foot or the shoe 20.

  As shown in FIG. 2, when the user wears the shoe 20, the user inserts the tip of the foot into the shoe 20. Next, the user puts the shoe slip prevention tool 2 between the rear end surface of the heel 22 and the shoehorn 24. As for the posture of the shoe slippage prevention tool 2 sandwiched, the upper space 16 is located above and the lower space 14 is located below. In this state, the shoehorn 24 is used as usual and the shoe 20 is put on. That is, the foot is inserted into the shoe 20 by sliding on the shoehorn 24 together with the shoe slip prevention device 2.

  With the above operation, the shoe slippage prevention tool 2 is firmly held by being pinched between the rear end surface of the heel 22 and the inner surface of the heel portion of the shoe 20, as shown in FIG. At this time, the cushion material 10 is likely to be located between the lower portion of the foot Achilles tendon portion 26 and the upper end edge 28 of the heel portion of the shoe 20. The support plate 8 is likely to be located between the rear end surface of the heel 22 and the inner surface of the heel portion of the shoe 20. As described above, the shoe slip prevention tool 2 can be easily mounted in the shoe 20. Moreover, the shoe slippage prevention tool 2 can be easily taken out simply by taking off the shoes in a normal manner. The removed shoe slip prevention tool 2 can be used again. This shoe slip prevention tool 2 can be used a plurality of times repeatedly.

  The shoehorn 24 is not limited to the use of the shoehorn 24 when the shoe slip prevention tool 2 is mounted. There are also shoes that can be easily worn without using the shoehorn 24. In such a case, although not shown, the vicinity of the crimping portion 12 of the shoe slippage prevention tool 2 is bent along the crimping portion 12. The shoe slip prevention tool 2 is hooked on the upper edge 28 of the heel of the shoe 20 in such a posture that the support plate 8 is located inside the shoe and the cushion material 10 is located outside the shoe. The foot is inserted into the shoe while lightly holding around the cushion material 10 with fingers. Then, as shown in FIG. 3, the shoe slip prevention tool 2 is sandwiched and held between the rear end surface of the heel 22 and the inner surface of the heel portion of the shoe 20.

  When the user walks or runs in a state where the shoe slip prevention tool 2 is mounted on the heel of the shoe 20, the bag bodies 4 and 6 rub against each other. The bag bodies 4 and 6 have lubricity. In particular, the bag bodies 4 and 6 made of a synthetic resin film have sufficient lubricity. In the rubbing between the bag bodies 4 and 6, the generated friction is very small. The rubbing between the bag bodies 4 and 6 can occur on both the foot side and the shoe side of the support plate 8. As a result, the effect of reducing friction is improved. Therefore, the frictional force from the shoe 20 is hardly transmitted to the heel 22 or the Achilles tendon portion 26. Further, the pressure from the shoe 20 on the foot can be relieved by the elasticity of the cushion material 10 and the support plate 8. Furthermore, since many step portions 18 of the corrugated cardboard constituting the support plate 8 extend in the vertical direction, the vertical movement of the foot with respect to the shoe 20 is smoothly guided.

  4 (a), 4 (b), and 4 (c) show shoe slip prevention devices 32, 34, and 36 having different configurations, respectively. In these shoe slippage prevention devices 32, 34, and 36, the same components as those in the shoe slippage prevention device 2 in FIG.

  4 differs from the shoe slippage prevention device 2 of FIG. 1 in that the crimp portion 12 is not formed on the outer bag body 38. The shoe slippage prevention device 32 shown in FIG. In other words, the outer bag body 38 is not separated into the upper and lower spaces 14 and 16. Furthermore, the cushion material 10 is not provided. Therefore, a large excess space 40 exists inside the outer bag body 38 in addition to the space occupied by the inner bag body 6 in which the support plate 8 is accommodated. In the case of the outer bag 38 made of a synthetic resin film, air can be enclosed in the excess space 40. This surplus space 40 may have cushioning properties. The other configuration of the shoe slip prevention tool 32 in FIG. 4A is the same as that of the shoe slip prevention tool 2 in FIG. The cushion material 10 may be inserted into the surplus space 40 in a fixed state or a non-fixed state.

  In the shoe slip prevention tool 32, the inner space of the outer bag 38 is large. In the case of the outer bag 38 made of a synthetic resin film, air can be enclosed therein. As a result, the inner bag body 6 can move greatly within the outer bag body 38. That is, the support plate 8 is easy to move. Furthermore, when the shoe slippage prevention device 32 is attached to the inside of the shoe 20, the air inside the outer bag body 38 is pushed upward by the heel 22 being pressed against the inner surface of the shoe 20. This upper air can be a cushion between the lower part of the foot Achilles tendon 26 and the upper edge 28 of the heel of the shoe 20. Other functions and effects are equivalent to the functions and effects of the shoe slip prevention tool 2 of FIG. Even if the shoe slippage prevention tool 2 of FIG. 1 is made of a synthetic resin film, an air cushion can be formed on the upper portion of the outer bag body 4 in the same manner as described above, provided that a vent portion is formed in the crimping portion 12. The mounting procedure of the shoe slip prevention tool 32 to the shoe 20 is the same as the mounting procedure of the shoe slip prevention tool 2 of FIG.

  The shoe slip prevention tool 34 shown in FIG. 4B is different from the shoe slip prevention tool 32 of FIG. 4A in that the size of the inner bag body 42 is considerably larger than that of the support plate 8, and the outer bag body. It is close to the size of 38. This inner bag body 42 is larger than the inner bag body 6 of the shoe slippage prevention tool 32 of FIG. In the shoe slippage prevention tool 34, the excessive space 40 described above is formed inside the inner bag body 42. The same components of the shoe slippage prevention tool 34 as those of the shoe slippage prevention tool 32 of FIG. 4A are denoted by the same reference numerals, and description thereof is omitted. The operational effects of the shoe slip prevention tool 34 are the same as those of the shoe slip prevention tool 32 shown in FIG. The manner in which the shoe slip prevention tool 34 is attached to the shoe 20 is the same as the manner in which the shoe slip prevention tool 2 in FIG.

  The shoe slippage prevention device 36 shown in FIG. 4C is different from the shoe slippage prevention device 34 in FIG. 4B in that the size of the support plate 44 is the support of the shoe slippage prevention device 34 in FIG. It is considerably larger than the plate 8 and close to the size of the inner bag body 42. The same components of the shoe slippage prevention device 36 as those of the shoe slippage prevention device 34 in FIG. 4B are denoted by the same reference numerals, and description thereof is omitted. The operational effect of the shoe slip prevention tool 36 is the same as that of the shoe slip prevention tool 32 of FIG. The manner in which the shoe slip prevention tool 36 is attached to the shoe 20 is the same as the manner in which the shoe slip prevention tool 2 in FIG.

  As described above, the shapes of the outer bag body, the inner bag body, the support plate, and the cushion material are not limited to rectangles. These may be, for example, a perfect circle, an oval, a triangle, an isosceles trapezoid, a pentagon, or the like. The outer shape of the cushion material may be a cylinder or the like. For example, when the bag body is an isosceles triangle, the bag body is attached to the inside of the shoe so that the bottom side is the lower side (shoe bottom side) and the apex angle is the upper side (Achilles tendon side). A cushion material is disposed on the apex side, and a support plate is disposed on the bottom side. In this case, the support plate may be formed in an isosceles trapezoidal shape. For example, in the case of a pentagonal bag, a cushion material is disposed on the apex side, and a support plate is disposed on the lower side. And it mounts | wears with the inside of shoes so that an apex angle may become an upper side. In this case, the support plate may be formed in a rectangular shape. For example, in the case of an isosceles trapezoidal bag body, a cushioning material is disposed on the narrow upper bottom side, and a support plate is disposed on a wide portion on the lower side. And it mounts | wears with the inside of shoes so that an upper base may become an upper side. In this case, the support plate may be formed in an isosceles trapezoidal shape. The upper part of the shoe slip prevention tool of these shapes is small. Therefore, even when slightly attached from the upper end of the shoe when attached to the shoe, it is difficult to stand out. On the other hand, since the lower part is wide, it is difficult to be displaced from side to side in the shoe during use.

  Each of the shoe slip prevention devices 2, 32, 34, 36 described above has the first bag after the support plates 8, 44 are stored in the second bag bodies (inner bag bodies) 6, 42 in advance. It is stored in the body (outer bag body) 4, 38. However, the present invention is not limited to such a configuration. The support plates 8 and 44 may be stored in the outer bag bodies 4 and 38 in a bare state without being stored in the inner bag bodies 6 and 42. For example, the inner bag bodies 6 and 42 may be removed from the shoe slip prevention devices 2, 32, 34, and 36 in FIGS. Even in such a shoe slip prevention tool, the outer bag bodies 4 and 38 rub against each other although the support plates 8 and 44 are interposed. The effect of reducing friction between the foot and the shoe is exhibited. However, as described above, in the shoe slippage prevention devices 2, 32, 34, and 36 including both the inner bag body and the outer bag body, the rubbing between the highly slippery bag bodies is caused by the foot side of the support plate. It can happen on both the shoe side. Due to this action, the effect of reducing friction between the foot and the shoes during walking is greatly improved. Therefore, it is preferable that the support plate is accommodated in the inner bag.

  The bag body is not limited to a single layer of the outer bag bodies 4 and 38 or a double body of the outer bag bodies 4 and 38 and the inner bag bodies 6 and 42. The bag may be triple or more. In this case, from the viewpoint of reducing friction, at least a double layer is preferably formed from a synthetic resin film. When the outermost bag is formed of a woven fabric or a non-woven fabric, damage due to external force can be suppressed. When forming a bag made of a synthetic resin in a double or more manner, it may be performed by heating and cutting at the same time.

  It is preferable that all of the above shoe slip prevention devices 2, 32, 34, and 36 have a length that can cover from the heel 22 to the lower part of the Achilles tendon 26. However, the length in the vertical direction of the shoe slip prevention tool can be changed according to the shape and structure of the shoe. If necessary, the length in the vertical direction may not extend from the lower end to the upper end of the inner surface of the collar portion. For example, the length in the vertical direction of the shoe slippage prevention tool 36 in FIG. 4C does not have to reach from the lower end to the upper end of the inner surface of the heel part. In addition, no extra space is required inside the inner bag bodies 6 and 42 in which the support plates 8 and 44 are stored.

  All of the shoe slippage prevention devices 2, 32, 34, and 36 described above are held between the foot and the inner surface of the shoe. However, the mounting method is not limited. For example, the shoe slip prevention devices 2, 32, 34, and 36 may be attached by bonding them to the inner surface of the shoe heel. For this purpose, for example, an adhesive layer may be formed on at least a part of one side of the shoe slip prevention tool 2, 32, 34, 36 by using an adhesive, a so-called double-sided adhesive tape or the like.

  The shoe slippage prevention device according to the present invention is easy to manufacture and its cost is low.
