Description

The present invention relates to footwear for use when cleaning a bathroom.

Footwear used when cleaning bathrooms has been widely known for some time now, as disclosed in, for example, Patent Document 1 and Patent Document 2, and is usually made of waterproof materials such as synthetic resins and rubber that do not allow water to pass through.

However, such footwear for use in the bathroom becomes wet when in use, and therefore needs to be hung out to dry after use. Conventionally, when drying such wet footwear, it has been common to hang it out with part of the footwear in contact with the bathroom floor, as described in Patent Document 2, for example.

However, when drying on the floor in this way, moisture can accumulate where the footwear comes into contact with the floor, making it difficult to dry and potentially causing mold and other hygiene problems. In addition to hygiene considerations, it is also desirable from the standpoint of efficient use of space to be able to easily store the footwear against a wall when not in use, allowing it to dry as well.

The bathroom footwear according to the first embodiment of the present invention will be described with reference to Figures 1 to 13. The bathroom footwear 1 is used to clean bathroom walls, floors, bathtubs, etc. without getting the feet wet. The bathroom footwear 1 comprises a footwear body 2, a magnet 3 attached to the sole 5 of the footwear body 2, and a waterproof cap 4 for covering the magnet 3. The components of these items will be described in detail below.

The footwear body 2 is made of a waterproof material such as rubber, and as shown in Figs. 2-4, has a sole 5 and an upper 6 that covers the user's foot above the sole 5. The upper 6 has a first upper part 6a that is arranged at the tip end of the longitudinal direction (axis L direction) and covers the toe side and instep side of the user's foot, and a second upper part 6b that is arranged at the rear end of the longitudinal direction and covers the ankle side and heel side. At the upper end of the second upper part 6b, a foot insertion opening 7 for inserting the user's foot is opened, and when the bathroom footwear is worn, the opening edge of the foot insertion opening 7 is located near the ankle. The upper 6 is formed symmetrically with respect to the axis L extending in the longitudinal direction, and the central part of the first upper part 6a in the axis L direction has a shape that protrudes most to the left and right (widthwise outward). This bathroom footwear 1 is shaped so that the opening edge of the foot insertion opening 7 is located near the ankle, but it may also be formed in a boot shape that covers the upper part of the ankle.

The second upper part 6b has a through hole 8 at the rear end where the heel abuts, and when putting on or taking off the footwear, a finger can be inserted into the through hole 8 to operate it, or a hanging device such as a hook can be hung on the through hole 8 to hang the bathroom footwear 1 in a specified location.

1 and 7, the sole 5 is formed of a first region 9 arranged at the tip end side in the longitudinal direction to support the toe side of the user's foot, a second region 10 arranged at the rear end side in the longitudinal direction to support the heel side of the user, and a third region 11 arranged between the first region 9 and the second region 10 to support the arch of the foot. Among a pair of side edges 12, 12 extending in the longitudinal direction of the sole 5 on both sides of the axis L, a pair of side edges 12a, 12a defining the first region 9 and a pair of side edges 12b, 12b defining the second region 10 are formed in a curved shape that convex outward in the width direction, while a pair of side edges 12c, 12c defining the third region 11 are formed in a curved shape that convex inward in the width direction.

As shown in Figs. 5 and 9, the sole 5 has an inner surface 5a that supports the sole of the foot inserted into the foot insertion opening 7, and an outer surface 5b that faces away from the inner surface 5a and abuts against the floor. The inner surface 5a of the sole 5 is formed as a flat surface parallel to the axis L in the first region 9, and from the third region 11 to the second region 10, it has a shape that slopes gently upward toward the rear. Note that a cushioning material such as an insole may be laid on the inner surface 5a as necessary.

The outer surface 5b of the sole 5 has a base surface 13 and a non-slip protrusion 14 erected downward from the base surface 13, and the base surface 13 is formed as a flat surface extending parallel to the inner surface 5a of the first region 9. Meanwhile, the protrusions 14 are arranged in a portion excluding the vicinity of the side edge 12, and are arranged in a concentric manner with a recess 17 (described later) provided in the widthwise center of the third region 11 as the center. Specifically, the protrusions 14 are composed of an annular protrusion 14A provided in the third region 11 and an arc-shaped protrusion 14B provided outside the annular protrusion 14A. The annular protrusion 14A is arranged so as to surround the recess 17, and the center of the circle is located on the axis L.

In the first region 9, the arc-shaped convex portion 14B is curved to be convex toward the tip end (toe side) in the longitudinal direction, and in the second region 10, it is curved to be convex toward the rear end (heel side) in the longitudinal direction. On the other hand, in the third region 11, the annular convex portion 14A is curved to be convex toward the toe side at the front side, the annular convex portion 14A is curved to be convex toward the heel side at the rear side, and the annular convex portion 14A is curved to be convex toward the outside in the width direction at the outside of the width direction. The wall width of these arc-shaped convex portions 14B is longer than the wall width of the annular convex portion 14A. In addition, the heights of the annular convex portion 14A and the arc-shaped convex portion 14B from the base surface 13 are equal to each other, and the tip surface 14a in the height direction (projection direction) of the annular convex portion 14A and the tip surface 14b in the height direction of the arc-shaped convex portion 14B are both on the same plane and are formed as a flat surface.

In addition, a first drainage groove 15 and a second drainage groove 16 are formed on the outer surface 5b of the sole 5, extending from the tip side to the rear end side in the longitudinal direction. The first and second drainage grooves 15, 16 are drainage grooves for improving drainage of water from the outer surface 5b of the sole 5, and the second drainage groove 16 is arranged on the outside in the width direction of the first drainage groove 15. The first and second drainage grooves 15, 16 are each arranged on both the left and right sides of the axis L, and are symmetrical with respect to the axis L. The first and second drainage grooves 15, 16 have front half portions 15a, 16a extending from the first region 9 on the toe side to the third region 11 of the arch portion, and rear half portions 15b, 16b extending from the third region 11 of the arch portion to the second region 10 on the heel side. The front half portions 15a, 16a are curved to form a gentle convex shape outward in the width direction, while the rear half portions 15b, 16b are curved to form a convex shape outward in the width direction with a curvature larger than that of the front half portions 15a, 16a. The first and second drainage grooves 15, 16 divide the arc-shaped convex portion 14B into pieces in the width direction.

Furthermore, as shown in Figs. 7-10, the third region 11 of the sole 5 is provided with the recess 17 that opens to the outer surface 5b side of the sole 5. The recess 17 has a concave circular storage section 25 to which the magnet 3 is attached, and an outer annular groove 20 that is formed concentrically at a position spaced outward from the circular storage section 25. The circular storage section 25 has a circular pedestal section 18 arranged at the center of the circular storage section 25, and an inner annular groove 19 (the "annular groove" in this invention) that is connected to the outside of the pedestal section 18 and formed concentrically, and that defines the pedestal section 18. The recess 17 is configured such that the pedestal section 18, the inner annular groove 19, and the outer annular groove 20 are arranged in this order from the center toward the outside in the radial direction. The sole 5 is formed symmetrically with respect to the axis L as a whole, and the center of the recess 17 is located on this axis L.

The base portion 18 protrudes downward from the groove bottom surface 19a of the inner annular groove 19, and its top surface 18a is located above the base surface 13 (toward the inner surface 5a of the sole 5). The top surface 18a of the base portion 18 forms the bottom wall of the recess 17 and is formed into a flat surface, with the magnet 3 being disposed on the top surface 18a.

The inner annular groove 19 and the outer annular groove 20 have the same groove width, and the groove bottom surface 19a of the inner annular groove 19 and the groove bottom surface 20a of the outer annular groove 20 are on the same plane and are located deeper than the base surface 13 in the depth direction (toward the inner surface 5a of the sole 5). In addition, an annular partition portion 21 is provided between the inner annular groove 19 and the outer annular groove 20 to separate the inner annular groove 19 and the outer annular groove 20. This partition portion 21 protrudes downward from the groove bottom surfaces 19a, 20a of the inner annular groove 19 and the outer annular groove 20, and its tip surface 21a is located below the top surface 18a of the pedestal portion 18 and the base surface 13.

As shown in FIG. 10, the magnet 3 is formed in a flat cylindrical shape, with one end face of the cylinder being an attraction surface 3a that exerts a magnetic attraction force, and the other end face on the opposite side being an abutment surface 3b that abuts against the top surface 18a of the base portion 18. The magnet 3 has the same diameter as the diameter of the base portion 18. The thickness of the magnet 3 is formed to be equal to the length from the top surface 18a of the base portion 18 to the tip surface 21a of the partition portion 21, so that when the magnet 3 is placed on the base portion 18, the attraction surface 3a and the tip surface 21a of the partition portion 21 are located on the same plane. Note that any permanent magnet such as a neodymium magnet is used as the magnet 3. The abutment surface 3b of the magnet 3 and the top surface 18a of the base portion 18 may be fixed with an adhesive.

The waterproof cap 4 is engaged with the recess 17 to cover the magnet 3 disposed within the recess 17. The waterproof cap 4 is formed of a synthetic resin having the same waterproof properties as the footwear body 2, and thermoplastic rubber (TPR) is used as the synthetic resin. The waterproof cap 4 has a plate-shaped cap body 22 that covers the attraction surface 3a of the magnet 3, an inner annular wall 23 (the "annular wall" in this invention) that stands from the inner surface 22a, which is one surface in the plate thickness direction of the cap body 22, and houses the magnet 3 therein, and an outer annular wall 24 that stands from the inner surface 22a of the cap body 22 and is formed concentrically outside the inner annular wall 23.

The cap body 22 is formed in a thin disk shape with a uniform thickness and flat front and back surfaces, and has the inner surface 22a, which is one side of the plate thickness direction, and a flat outer surface 22b, which is the other side of the plate thickness direction. The inner surface 22a side is arranged so that it faces the inner surface 5a side (upper side) of the sole 5, and the outer surface 22b side of the cap body 22 is arranged so that it faces the outer surface 5b side (lower side) of the sole 5. The plate thickness of the cap body 22 is formed to be equal to the length from the tip surface 21a of the partition part 21 to the tip surface 14a (14b) of the protrusion part 14. In addition, this cap body 22 has the same diameter as the outer peripheral wall of the outer annular groove 20 of the recess 17, and when the waterproof cap 4 is attached to the recess 17, the cap body 22 covers the entire recess 17 from the outer surface 5b side of the sole 5. The waterproof cap 4 may be fixed to the sole 5 in the recess 17 by adhesive.

The inner annular wall 23 fits into the inner annular groove 19 of the recess 17, and the diameter of the circle enclosed by the inner peripheral wall of the inner annular wall 23 is formed to be approximately the same as the diameter of the base portion 18 and the diameter of the magnet 3 that is abutted against the base portion 18, so that the base portion 18 and the magnet 3 are housed within the inner peripheral wall.

The outer annular wall 24 fits into the outer annular groove 20 of the recess 17 and is provided on the outer peripheral edge of the cap body 22. The wall width of the outer annular wall 24 is formed to be the same length as the wall width of the inner annular wall 23, and is also formed to be the same length as the groove widths of the inner annular groove 19 and the outer annular groove 20 in the recess 17. In addition, the tip surface 24a in the height direction of the outer annular wall 24 is located on the same plane as the tip surface 23a of the inner annular wall 23.

When the waterproof cap 4 is attached to the recess 17, the outer annular groove 20 and the outer annular wall 24 are elastically fitted together with the tip surface 24a of the outer annular wall 24 abutting against the groove bottom surface 20a of the outer annular groove 20, and the inner annular groove 19 and the inner annular wall 23 are elastically fitted together with the tip surface 23a of the inner annular wall 23 abutting against the groove bottom surface 19a of the inner annular groove 19. In this fitted state, the tip surface 21a of the partition portion 21 in the recess 17 abuts against the inner surface 22a of the cap body 22 located between the outer annular wall 24 and the inner annular wall 23.

The magnet 3 has its contact surface 3b contacting the top surface 18a of the base portion 18, and its opposite attracting surface 3a contacting the inner surface 22a of the cap body 22 partitioned by the inner annular wall 23, and is housed together with the base portion 18 within the inner annular wall 23. The attracting surface 3a of the magnet 3 is slightly closer to the tip surface 14a (14b) of the convex portion 14 than the base surface 13, and is located on the same plane as the tip surface 21a of the partition portion 21.

As described above, the waterproof cap 4 has a plate thickness of the cap body 22 equal to the length from the tip surface 21a of the partition wall 21, where the inner surface 22a of the cap body 22 abuts, to the tip surface 14a (14b) of the convex portion 14. Therefore, the outer surface 22b of the cap body 22 is configured to be located on the same plane as the tip surface 14a (14b) of the convex portion 14, and the outer surface 22b does not protrude below the convex portion 14, so as not to impede ease of walking. However, as long as it does not impede ease of walking, it is also possible to position the attraction surface 3a of the magnet 3 on the same plane as the tip surface 14a (14b) of the convex portion 14, for example, and to make the outer surface 22b of the waterproof cap 4 protrude below the convex portion 14.

When the cap is worn, the mating portion between the outer annular groove 20 and the outer annular wall 24 becomes the first seal on the outside, and the mating portion between the inner annular groove 19 and the inner annular wall 23 becomes the second seal on the inside. Therefore, the waterproof cap 4 is attached liquid-tight to the recess 17, so that even if the floor of the bathroom is wet with water, water does not reach the magnet 3. In addition, the waterproof cap 4 is prevented from accidentally falling off the recess 17 by the elastic friction force generated at the mating portion between the outer annular groove 20 and the outer annular wall 24 and the mating portion between the inner annular groove 19 and the inner annular wall 23. In particular, when the waterproof cap 4 is fixed to the sole 5 with an adhesive, it is possible to more reliably prevent water from entering the recess 17 and the waterproof cap 4 from falling off the recess 17. Furthermore, since the magnet 3 is attached to the third region 11 that supports the arch part that is not easily subjected to force when walking, the user is less likely to feel discomfort due to the magnet 3 being attached.

The bathroom footwear 1 having the above-mentioned configuration has a magnet 3 attached to the outer surface 5b of the sole 5, so that after cleaning the bathroom, the footwear can be easily stored on the wall W, which is made of a magnetic material such as the side of a washing machine, by placing the outer surface 5b facing the wall W as shown in FIG. 13 and allowing the magnet 3 to adhere to the wall W, thereby drying the footwear. If the footwear is stored with the rear end side through which the through hole 8 is formed facing down, water can be drained more easily, even if the inside and outside of the footwear are wet, such as after washing.

Figures 14 to 19 show bathroom footwear 1A according to a second embodiment of the present invention. In order to avoid duplication, detailed descriptions of the configuration and effects similar to those of the first embodiment will be omitted.

The bathroom footwear 1A according to this second embodiment differs from the bathroom footwear 1 according to the first embodiment mainly in the shape of the heel-covering portion at the rear end of the upper 6 (rear end of the second upper portion 6b), the shape of the tip of the sole 5, the shape of the recess 17A that opens into the sole 5 and in which the cylindrical magnet 3 is attached, and the shape of the waterproof cap 4A that water-tightly covers the attached magnet 3 in the recess 17A, i.e., the retention structure of the magnet 3 in the bathroom footwear 1A.

Specifically, in this embodiment, the rear end of the second upper part 6b is formed in a shape that is curved inwardly and convex, as shown in the cross section of FIG. 15, and the through hole 8 is provided through the inwardly curved portion. The rear end of the second upper part 6b protrudes upward from a pair of side parts connected to both sides of the rear end. In addition, the tip part of the sole 5 that supports the toes of the foot has a shape that is curved in a downward convex shape from the rear end side to the tip end side, which allows the rear end side of the footwear 1A to better follow the movement of the heel when walking, and prevents the heel from slipping out of the foot insertion opening 7.

Next, the holding structure of the magnet 3 in this embodiment will be specifically described.
14 to 18, the recess 17A formed in the third region 11 of the sole 5 has a concave circular housing 25 to which the magnet 3 is attached, and a flange housing 26 connected to the outer periphery of the circular housing 25 to house a flange 22c of a waterproof cap 4A described later. As in the first embodiment, the circular housing 25 has a circular base 18 disposed in the center, and an annular groove 19 connected to the outer side of the base 18 and formed concentrically with the base 18, and the diameter of the base 18 is formed to be substantially the same as the diameter of the magnet 3.

However, the annular groove 19 in this embodiment corresponds to the inner annular groove 19 in the first embodiment. The recess 17A is configured such that the seat portion 18, the annular groove 19, and the flange accommodating portion 26 are arranged in this order from the center toward the radially outward direction. In the sole 5 formed symmetrically about the axis L, the center of the recess 17A is located at the same position as the center of the recess 17 in the first embodiment.

In this embodiment, the waterproof cap 4A has a plate-shaped cap body 22 that covers the attraction surface 3a of the magnet 3, and an annular wall 23 that is erected from the inner surface 22a, which is one side surface of the cap body 22 in the plate thickness direction, and has an inner diameter substantially the same as the diameter of the magnet 3, and the magnet 3 is accommodated in a concave space 23b surrounded by the annular wall 23. The cap body 22 has an outer surface 22b that faces the inner surface 22a and is formed flat, and has a flange portion 22c of uniform thickness that is connected from the outer periphery of the annular wall 23 toward the radially outward side. In addition, in the cap body 22, the thickness of the flange portion 22c is formed slightly thicker than the thickness of the portion that forms the bottom wall of the concave space 23b surrounded by the annular wall 23, i.e., the portion that directly abuts and covers the attraction surface 3a of the magnet 3. Specifically, the length from the outer surface 22b to the inner surface 22a of the cap body 22 is slightly longer at the flange 22c than at the bottom wall of the recessed space 23b.

The outer periphery of the flange 22c of the waterproof cap 4A is formed by a pair of outer periphery arc portions 22d, 22d that are concentric with the annular wall 23 and face each other, and a pair of outer periphery straight portions 22e, 22e that connect both ends of the outer periphery arc portions in parallel to each other. On the other hand, the inner periphery into which the outer periphery of the flange 22c is fitted in the flange accommodating portion 26 of the recess 17A is formed by inner periphery arc portions 26a, 26a that face the pair of outer periphery arc portions 22d, 22d of the flange 22c of the waterproof cap 4A, and a pair of inner periphery straight portions 26b, 26b that face the pair of outer periphery straight portions 22e, 22e.

At this time, the inner circumferential arc portion 26a is concentric with the circular storage portion 25, has substantially the same diameter and circumferential length as the outer circumferential arc portion 22d, and the inner circumferential straight portion 26b has substantially the same length as the outer circumferential straight portion 22e. In addition, in the sole 5, the pair of inner circumferential straight portions 26b, 26b of the recess 17A extend in the width direction perpendicular to the axis L, and the pair of inner circumferential arc portions 26a, 26a are arranged on both sides of the axis L in the width direction and face each other back to back. If it is desired to specify the direction in which the waterproof cap 4A is fitted to the recess 17A, as shown in FIG. 18, a first mark S1 may be provided on the recess 17A and a second mark S2 may be provided on the inner surface 22a of the waterproof cap 4A, and when the waterproof cap 4A is attached to the recess 17A, these marks S1 and S2 may be aligned to face each other to position them.

In addition, the depth of the concave space 23b in the waterproof cap 4A, i.e., the dimension from the tip surface 23a of the annular wall 23 to the inner surface 22a forming the bottom wall of the concave space 23b, is substantially equal to the sum of the dimension from the groove bottom surface 19a of the annular groove 19 to the top surface 18a of the pedestal portion 18 (i.e., the height of the pedestal portion 18) and the thickness of the magnet 3 (the length between the attraction surface 3a and the abutment surface 3b). Furthermore, in the recess, the flange accommodating portion 26 has a uniform depth from the tip surface 14a of the annular protrusion 14A, and the depth is formed to be the same as the thickness of the flange portion 22c. In other words, the length from the tip surface 14a of the annular protrusion 14A to the bottom surface 26c of the flange accommodating portion 26 and the length from the outer surface 22b of the cap body 22 to the inner surface 22f of the flange portion 22c of the inner surface 22a are equal to each other. The depth of the recess 17A (i.e., the length from the groove bottom surface 19a to the tip surface 14a of the annular protrusion 14A) and the thickness of the waterproof cap 4A (i.e., the length from the tip surface 23a of the annular wall 23 to the outer surface 22b of the cap body 22) are substantially equal.

When the magnet 3 and the waterproof cap 4A are attached to the recess 17A, the waterproof cap 4A is positioned relative to the recess so that the outer circumferential arc portion 22d of the flange portion 22c corresponds to the inner circumferential arc portion 26a of the recess 17A, and the outer circumferential straight portion 22e of the flange portion 22c corresponds to the inner circumferential straight portion of the recess 17A. Then, with the abutment surface 3b of the magnet 3 abutting or adhering to the top surface 18a of the base portion 18, the tip surface 23a of the annular wall 23 abuts against the groove bottom surface 19a of the annular groove 19, and at the same time, the waterproof cap 4A is fitted into the recess 17A until the inner surface 22f of the flange portion 22c abuts against the bottom surface 26c of the flange accommodating portion 26.

Then, the concave space 23b in which the magnet 3 is accommodated is watertightly sealed by fitting into the annular groove 19 of the annular wall 23. Furthermore, in this fitted state, if the inner surface 22f of the flange portion 22c is adhered or fixed to the bottom surface 26c of the flange housing portion 26 with an adhesive or the like, the waterproof cap 4A can be prevented from coming off the recess 17A and the watertightness of the concave space 23b can be improved, which is more preferable. Also in this embodiment, the magnet 3 is fitted into the concave space 23b and is sandwiched between the bottom wall (cap body 22) of the concave space 23b and the base portion 18, so that the magnet 3 can be stably attached to the recess 17A. Furthermore, the outer surface 22b of the cap body 22 is located on the same plane as the tip surface 14a of the annular protrusion 14A, and the magnet 3 is attached to the third region 11 that supports the arch of the foot, so that the attachment of the magnet 3 to the sole 5 does not interfere with walking.

In this embodiment, as in the first embodiment, the heights of the annular convex portion 14A and the arcuate convex portion 14B from the base surface 13 are equal to each other. In addition, the arrangements of the annular convex portion 14A and the arcuate convex portion 14B, as well as the first drainage groove 15 and the second drainage groove 16 in each region 9, 10, and 11 of the sole 5 are substantially the same in both embodiments.

As with the bathroom footwear 1 according to the first embodiment, the bathroom footwear 1A according to this embodiment can be easily stored on a wall W after cleaning the bathroom by adhering the magnet 3 to the wall W, as shown in FIG. 19, for example. In this case, the thickness of the part of the cap body 22 that forms the bottom wall of the recessed space 23b in which the magnet 3 is housed is thinner than the other parts, making it possible to attach the footwear to the wall W with a stronger adsorption force. In addition, the tip of the sole 5 in the direction of the axis L is curved and rises from the wall W, making it easy to remove from the wall W.

Although the embodiments of the bathroom footwear according to the present invention have been described above, the present invention is not limited to the above-mentioned embodiments, and various design modifications are possible within the scope of the claims. In this embodiment, the recess 17 is disposed on the axis L in the third region 11 of the sole 5, but the present invention is not limited thereto, and may be disposed in other regions of the sole 5 or other parts not on the axis L. In addition, the circular storage portion 25 is formed on a stepped bottom wall surface by having the pedestal portion 18 and the inner annular groove 19, but it can also be formed on a flat surface as long as the magnet 3 and the inner annular wall 23 are accommodated within the circular storage portion 25.
