Abstract
Description
[Technical Field]
[0001] The present invention relates to footwear used when a person sits on a Western-style toilet seat to defecate, and in particular to footwear that allows the person to lean forward (bringing both feet closer to the abdomen) as if using a squat toilet, relaxing the puborectalis muscles and stretching the area from the rectum to the anus, allowing for smooth defecation. [Background technology]
[0002] When people defecate, both in the East and the West, they usually lean forward (squatting with their knees close to their abdomen). This position relaxes the puborectalis muscle, eliminating the bending from the rectum to the anus, and promotes smooth defecation. Even in the West, the spread of seated toilets was relatively new, occurring from the late 19th century to the early 20th century. Furthermore, this position is thought to be more suitable for Asians, who consume more carbohydrates than meat compared to Caucasians.
[0003] However, with the global trend toward Western-style toilets, Western-style toilets, which require a person to sit down to defecate, have become widespread. When sitting on these toilets, the knees cannot be positioned close to the person's abdomen, as in the position required for defecation on a Japanese-style toilet, as shown in Figure 5(a). When sitting on a Western-style toilet (51), the path from the person's rectum to the anus forms a "L" shape, causing the stool to get stuck in the middle, as shown in the enlarged view of Figure 5(b). Therefore, using a footrest (52), as shown in Figure 5(c), allows the person to assume a "forward-leaning" position. In this position, the puborectalis muscle relaxes, stretching the "L" shape from the rectum to the anus, making it easier to pass stool, as shown in the enlarged view of Figure 5(d). This position, similar to squatting, compresses the abdomen with the thighs, creating greater abdominal pressure and facilitating defecation.
[0004] The ideal posture for defecation is a forward-leaning position with an angle of approximately 35 degrees between the trunk and thighs, as shown in Figure 5(c). Therefore, several technologies have been proposed for footrests (52) that allow a person to squat down while defecating on a Western-style toilet (51), as with a Japanese-style toilet, with their knees positioned close to their abdomen. The footrests allow the person to place both feet on a platform and adjust the position of their trunk and thighs to achieve a position similar to that of a Japanese-style toilet. For example, the "toilet footrest" described in Patent Document 1 allows a person to place their feet on a platform to achieve a similar posture when using a Western-style toilet as when using a Japanese-style toilet. Its extremely simple structure has been proposed to naturally stimulate the urge to defecate and prevent constipation. Such toilet footrests come in a variety of types, including those that are integrated with the toilet, movable types, corset-like attachments that are hung over the toilet, and separate units, as well as foldable units such as the "Footrest for Western-style Toilets" in Patent Document 2.

[0006] [Non-Patent Document 1] Manufacturer / Distributor: Crocs, Inc. URL: https: / / www.crocs.co.jp / p / crocs-siren-clog / 208547.html?cgid=collections-clogs&cid=2Y2 Accessed: August 21, 2025 [Non-patent document 2] Manufacturer / Seller: Parade URL: https: / / store.shopping.yahoo.co.jp / zozo / 83600687.html Accessed: August 21, 2025 Summary of the Invention [Problem to be solved by the invention]
[0007] Foot rests attached to the toilet itself, such as the "toilet foot rest" in Patent Document 1, not only hit the body when used for purposes other than defecation, but also get in the way when sitting on the toilet, standing up, or cleaning the Western-style toilet. Additionally, the "toilet foot rest" in Patent Document 1 has the problem that, because it is not installed on the floor, it easily comes off the toilet if too much weight is put on it during use.
[0008] In addition to the "toilet footrest" of Patent Document 1, several other footrest aids have been proposed. Many of these footrest aids are intended for use by infants when urinating on an adult Western-style toilet or when sitting on the toilet seat, or to encourage bowel movements. Many proposed footrests are rectangular in shape, suitable for an adult male standing in front of the toilet bowl, or arc-shaped, covering the bottom of the toilet bowl, and are several tens of centimeters high. As shown in Figure 5(c), these footrests take up a large amount of space in front of the Western-style toilet (51). While they can be moved and stored in a spacious toilet room, in a small room, the footrest can become a nuisance when not in use. Furthermore, consideration must be given to preventing falls when sitting on or standing up from the toilet bowl.
[0009] To solve this problem, foldable footrests such as the "Footrest for Western-style Toilets" in Patent Document 2 and footrests that connect the left and right sides when in use such as the "Step Stool for Toilets" in Patent Document 3 have been proposed, but they still require setting up each time they are used and require care when sitting on or standing up from the toilet, and when the shape of these footrests is complex, it is difficult to maintain hygiene. Also, these footrests limit the size of the area where the feet can be placed, which inevitably restricts the way people spread their legs, which varies from person to person.
[0010] Furthermore, a shoe sole shape that lifts the toes to encourage bowel movements has also been proposed, such as the "footwear sole" in Patent Document 4. However, at the height shown in the example, it is necessary to bend forward significantly to form an angle of approximately 35 degrees between the trunk and thighs, and the shape is not suitable for walking or standing up.
[0011] The inventor of this invention realized that by using thick-soled footwear instead of a footrest, a person can maintain a posture with both feet raised when sitting on a toilet bowl. Furthermore, footwear would not get in the way even when not in use, even in a small toilet room, and if it could be easily washed, it would be possible to use it hygienically.
[0012] Non-Patent Documents 1 and 2 describe footwear available commercially online, primarily intended for outdoor use, and designed to stay on the feet while walking. The footwear in Non-Patent Document 1 has a front-to-back shape in side view that angles downward from the heel to the front and upward from the base of the toes to the toes. As a result, when sitting on a toilet, the angle between the ankle to the thigh and the ankle to the toes in side view is an obtuse angle greater than 90 degrees, resulting in an unnatural posture that makes it difficult to strain, and when standing up while wearing the footwear, the body is pushed forward, resulting in an unstable posture. The footwear in Non-Patent Document 2 also has a front-to-back shape in a side view that angles downward from the heel forward at a large angle. As a result, when assuming a posture similar to sitting on a toilet, the angle between the direction from the ankle to the thigh and the direction from the ankle to the toes in a side view is an obtuse angle greater than 90 degrees, resulting in an unnatural posture that makes it difficult to strain, and when standing up while wearing the footwear, the body tends to be pushed forward, making the posture unstable. The footwear of Non-Patent Document 2 also has a strap that secures the heel, which makes it extremely time-consuming to put on and take off the footwear, making it unsuitable for use for defecation. Furthermore, the footwear of Non-Patent Documents 1 and 2 are designed to be flexible and pliable to make walking easier, but these can make the footwear unstable when standing up carelessly, which can lead to the risk of falling. Excessive decorative exteriors on footwear, including those of Non-Patent Documents 1 and 2, are unsuitable for footwear intended for defecation because they are difficult to clean when soiled and difficult to keep clean.
[0013] The present invention was created to solve these problems. Specifically, the purpose of the present invention is to use thick-soled footwear to naturally maintain a posture in which the feet are placed on the footrest while sitting on the toilet seat, without restricting the width of the legs. Furthermore, a foot slip prevention mechanism is provided on the upper part of the footwear to prevent excessive slippage of the feet placed on the footrest. The footwear is lightweight and has little deformation in the front-to-back, up-down, and left-to-right directions, thereby avoiding the risk of falling even if the person stands up unintentionally while wearing the footwear. [Means for solving the problem]
[0014] The present invention provides footwear (1), (11), (21) for Western-style toilets that, when a person sits on a Western-style toilet seat, allows the person to place their feet and adjust the position of their torso and thighs to assume a forward-leaning position as if they were using a Japanese-style toilet, allowing them to change their position so that they can defecate with their rectum and anus stretched. The footwear is characterized by comprising upper footwear bodies (2), (12), (22); soles (3), (13), (23) that support the upper footwear bodies (2), (12), (22) and have a thickness that allows the person's feet to be lifted when sitting on the toilet seat; and foot slip prevention mechanisms (4), (14), (16), (24), (25) that are arranged on the sides of the upper footwear bodies (2), (12), (22) or the soles (3), (13) to prevent the foot from slipping when placed on the upper footwear bodies (2), (12), (22). [Effects of the Invention]
[0015] The footwear (1), (11), and (21) for Western-style toilets of the present invention can be used by sitting on a Western-style toilet (51), placing both feet on the upper parts (2), (12), and (22) of the footwear, and using the foot slip prevention mechanisms (4), (14), (16), (24), and (25) to secure the foot by covering the top of the foot, hooking only the toes, or aligning the upward convex shape of the sole of the foot between the toes. When a person sitting on a Western-style toilet (51) places both feet on the upper parts (2), (12), and (22), they can maintain a posture with their feet elevated, allowing them to assume a "forward-leaning" position, similar to that when using a Japanese-style toilet, with their knees close to their abdomen. In this position, the body is stretched from the rectum to the anus, allowing for natural straining without straining, resulting in smooth bowel movements.
[0016] The projected area (maximum value: front-to-back width (length) x left-to-right width (length)) of footwear for Western-style toilets (1), (11), and (21) in a plan view (viewed from above) is the same as that of regular slippers or sandals, allowing them to be placed or stored compactly. Therefore, they can be placed or stored unobtrusively at the foot of a Western-style toilet (51), in a toilet room, or in a small modular bathroom. Furthermore, because the projected area in a plan view is the same as that of regular slippers or sandals, there is no limitation on the size of the footrest, as there is with the "footrest for Western-style toilets" in Patent Document 2 and the "toilet step stool" in Patent Document 3, and there is no need to restrict the different straddle positions of individuals.
[0017] Furthermore, footwear for Western-style toilets (1), (11), and (21) undergo minimal change in shape before and after use, and are not subject to inadvertent deformation during use, as is the case with footrests designed for storage such as those in Patent Document 1 or Patent Document 2. They can be used safely while maintaining their shape, and even if one stands up carelessly while wearing them, the risk of falling or other dangers can be avoided.
[0018] The foot slip prevention mechanism (4) is located on the upper part of the footwear body (2), and has a width (length) in the front-to-back direction when viewed from the top and side, and is a band-like shape with a semicircular arc extending upward from the left end to the right end when viewed from the front and back.The foot can be slipped under the semicircular arc to secure the foot in place, covering the instep. The slippage prevention mechanism (14) is arranged on the side of the sole (13), and is a band-like structure having a semicircular arc shape similar to the slippage prevention mechanism (4), and is structured so that it can swing back and forth with the slippage prevention mechanism fixture (15) as a fulcrum, and the foot can be slid under the semicircular arc shape from either the front or the back and positioned so that the instep is covered. Two anti-slip mechanisms (16) are arranged on the upper part of the footwear body (12) near both ends in the front and rear directions, and are used by stepping on one and sliding the foot onto the remaining one. The slippage prevention mechanism (24) is arranged on the upper part (22) of the footwear body as one or more upwardly projecting portions that match the shape of the sole of the foot, and is used by fitting it along the spaces between the toes. The slippage prevention mechanism (25) is arranged on the upper part (22) of the footwear body in a shape that covers only the toes. The anti-slip mechanisms (4), (14), (16), (24), and (25) are intended to prevent excessive slippage of the feet placed on the upper footwear bodies (2), (12), and (22). The strap shapes of the anti-slip mechanisms (4), (14), and (16) were designed to clearly show that they are capable of preventing excessive slippage with almost no slippage of the feet, while the shapes of the anti-slip mechanisms (24) and (25) were designed to show that they are capable of preventing excessive slippage while assuming (accepting) some degree of foot slippage. Thus, the anti-slip mechanisms, which are components of footwear for Western-style toilets in this invention, are only required to prevent excessive slippage of the feet, and the placement of the anti-slip mechanisms (4), (14), (16), (24), and (25) helps to avoid the risk of falling even if the wearer inadvertently stands up while wearing the footwear. Although not described in the examples below, if it is possible to prevent excessive slippage of a foot placed on the upper parts of the footwear body (2), (12), (22) by, for example, making the upper parts of the footwear body (2), (12), (22) concave to match the shape of the sole of the foot, it is not essential to provide the foot slip prevention mechanisms (4), (14), (16), (24), (25).

DETAILED DESCRIPTION OF THE INVENTION
[0020] The footwear for Western-style toilets of the present invention is an assistive device that allows a person to change their position when sitting on a Western-style toilet seat by placing both feet on it and adjusting the position of their trunk and thighs to assume a forward-leaning position as if they were using a Japanese-style toilet, allowing them to defecate with their rectum and anus stretched. Hereinafter, embodiments of the present invention will be described with reference to the drawings of Examples 1 to 3. [Example]
[0021] <Configuration of footwear for Western-style toilets> 1 is a side view showing the state in which footwear for Western-style toilets of Example 1 is used. Footwear for Western-style toilets of Examples 2 and 3 described below are also used in the same state. FIG. 2 is a perspective view showing footwear for a Western-style toilet according to the first embodiment. The footwear (1) for a Western-style toilet in Example 1 is composed of three components: an upper part (2) of the footwear body on which the foot rests; a sole (3) that supports the upper part (2) of the footwear body and has a thickness (height) in the vertical direction that lifts the foot when sitting on the toilet seat; and a foot slip prevention mechanism (4) that is arranged to prevent excessive slippage of the foot placed on the upper part (2) of the footwear body.
[0022] The tall sole (3) is a generally rectangular parallelepiped-shaped member whose vertical thickness (height) in a side view is generally the same from the front (toe direction) to the rear (heel direction), as shown in Figure 2, and maintains the height of the upper footwear body (2) at the location where the toes rest and the location where the heel rests at approximately the same height. The generally rectangular parallelepiped shape here includes a rectangular parallelepiped shape in which the vertical thickness (height) in the front (toe direction) and the vertical thickness (height) in the rear (heel direction) are the same and there is no angle from the rear (heel direction) to the front (toe direction), as well as a shape in which the vertical thickness (height) in the front (toe direction) is slightly smaller than the vertical thickness (height) in the rear (heel direction) and there is an angle downward from the rear (heel direction) to the front, but the angle is not large. Shapes that have a large downward angle from the heel toward the front, such as the footwear in Non-Patent Documents 1 and 2, are not included in the roughly rectangular parallelepiped shape. As shown in Figure 1, the sole (3) is a component that allows the angle between the trunk and thighs to be approximately 35 degrees when sitting on the Western-style toilet (51), and the height from the bottom surface to the upper part of the footwear body (2) in the vertical direction is preferably 10 to 20 cm. Due to the material of the upper part of the footwear body (2), the sole (3) is preferably molded integrally with the upper part of the footwear body (2), but it may also be molded separately from the upper part of the footwear body (2) and joined by adhesive or welding. Furthermore, as shown in Figure 2, a slip-prevention mechanism (4) is disposed on top of the upper footwear body (2) to secure the foot so as to cover the instep and prevent excessive slippage of the foot. As shown in Figure 2, the slip-prevention mechanism (4) is a band-like structure that has a width (length) in the front-to-back direction in plan and side views and has a semicircular arc shape extending upward from the left end to the right end in front and back views. This band-like shape enables the slip-prevention mechanism (4) to secure the foot so as to cover the instep and prevent excessive slippage of the foot.
[0023] Various synthetic resins can be used for the materials of each component, and the type and processing method (e.g., foaming) are not particularly important as long as they are strong and rigid enough to withstand use. For example, taking into consideration lightness, elasticity including cushioning, and deformability to external forces after shaping, ethylene vinyl acetate copolymer (EVA) resin can be used to achieve a comfortable fit, polyvinyl chloride (PVC) resin can be used for stain resistance and durability, polystyrene (PS) resin can be lightweight and highly rigid, and urethane resin produced by the polyaddition of compounds containing isocyanate groups and hydroxyl groups can be used alone or in combination. While a single-material integral molding is preferable, moldings made from other resins such as styrene resin and ABS resin can also be used.
[0024] The upper surface of the upper footwear body (2) and the anti-slip mechanism (4) can be treated with an anti-slip or sweat-wicking treatment, and the bottom surface of the sole (3) can also be treated with an anti-slip treatment. Furthermore, the shape can be treated with a wavy or multiple protrusions, as used in common footwear including slippers, sandals, and boots, to provide an anti-slip effect and prevent discomfort caused by sweating from the soles. When such treatments are applied, it is preferable to choose a shape that allows the footwear for Western-style toilets (1) to be easily cleaned when it becomes soiled.
[0025] The sole (3) needs to be able to stably support the weight of the user not only when the user sits down with their feet on the upper part of the footwear body (2), but also when the user stands up unintentionally. Normal footwear requires flexibility in the front-to-back direction and cushioning in the up-down and left-to-right directions, but in footwear for Western-style toilets (1), which has the characteristic that the height from the bottom of the sole (3) to the upper part of the footwear body (2) is higher than that of general commercially available footwear, it is preferable to minimize deformation as much as possible, and it is preferable that the sole be made of a material that keeps deformation to less than 20% in response to inputs such as body weight load.
[0026] As long as the sole (3) can support the upper part of the footwear body (2), there are no particular limitations on the structure or shape of the interior or sides; for example, it may have a storage space inside. Furthermore, as long as the sole (3) can support the upper part of the footwear body (2), it may be provided as a separate component completely separated from the upper part of the footwear body (2), or it may be made of several components stacked together to form a component with an adjustable height. While this is not a problem when sitting down, it is preferable that the weight per foot be less than 1.5 kg and that the material have a specific gravity to volume ratio of less than 1 to prevent falling when standing up carelessly.
[0027] The slippage prevention mechanism (4) shown in Example 1 covers the instep to prevent the foot from slipping excessively off the footwear main body upper part (2) during use, but its shape does not have to be a band-like shape that covers the instep as shown in Figure 2. As long as the foot placed on the footwear main body upper part (2) does not slip excessively, it may be a structure that covers the entire foot from the toes to the instep, that hooks only the toes, or that has an upward convex shape that matches the shape of the sole and fits between the toes. The slippage prevention mechanisms (24) and (25) shown in Example 3 described below have a structure that hooks only the toes or has an upward convex shape that matches the shape of the sole and fits between the toes.
[0028] <How to use footwear for Western-style toilets> The footwear (1) for Western-style toilets of Example 1 is worn on both feet while sitting on a Western-style toilet (51), as shown in Figure 1. It does not matter whether the footwear is worn beforehand or after sitting down, but to prevent falls and injuries, it is usually preferable to slide the foot forward under the foot slip prevention mechanism (4) after sitting down, and then place the sole of the foot on the upper part of the footwear body (2) so that the foot slip prevention mechanism (4) covers the top of the foot and secures the foot to the footwear.
[0029] The footwear (1) for Western-style toilets is a pair of products, with the left and right thighs being able to move independently, without restricting the range of movement. When a person (h) sitting on a Western-style toilet (51) places both feet on the upper part of the footwear body (2), the puborectalis muscles relax, stretching the area from the rectum to the anus, as shown in the enlarged view of Figure 5(d). Furthermore, abdominal pressure is more easily applied, making it easier to naturally exert force, allowing for smooth defecation without excessive straining.
[0030] <Condition of footwear for Western-style toilets after use> When not in use, the footwear (1) for Western-style toilets can be stored side by side. While it does not require as much space as a folding platform, such as the "footrest for Western-style toilets" in Patent Document 2, it can be stored without taking up too much space, even at the foot of a Western-style toilet (51), in a small toilet room, or in a modular bathroom, and can be used immediately without any special procedures. Furthermore, footwear made of lightweight materials such as foam resin does not necessarily need to be placed on the floor; it can also be stored by hanging it on a wall or on a storage stand.
[0031] Furthermore, both feet of the footwear (1) for Western-style toilets can be easily removed after defecation. Therefore, unlike the footrests (52) proposed in several publications, when standing up from the Western-style toilet (51), removing the footwear allows the thighs to be nearly level with the floor, making it possible to stand up with less effort and preventing injuries such as tripping over. Furthermore, even if the soles (3) are thick, it is easy to avoid tripping over, since the shoes are not primarily intended for walking and are used in limited indoor spaces where the wall can be easily reached and the floor is nearly level.
[0032] The upper part of the footwear (2) and the sole (3) were made of foamed plastic made primarily of polystyrene resin, measuring 15 cm in height, and a foot slip prevention mechanism (4) made of Styrofoam cloth was placed on the upper part of the footwear (2), creating footwear for Western-style toilets (1), which was then tested. There was no problem putting on and taking off the shoes while sitting or standing without sitting. Furthermore, there was no sense of instability when walking or standing while wearing them. Therefore, even when reaching high up while standing, the feet remained stable as if they were standing on the floor, and tasks such as picking up objects or wiping walls could be performed without losing posture. Each foot weighed 150g, its volume was calculated to be 4000cm3 (cubic centimeters), and its specific gravity was 0.0375. [Example]
[0033] <Configuration of footwear for Western-style toilets that can be used from both directions> Figure 3 is a perspective view showing footwear (11) for Western-style toilets of Example 2 that can be used in both directions. "Both directions" refers to the front direction (left direction in the drawing) and the rear direction (right direction in the drawing). (a) shows the state and operation of a foot slip prevention mechanism (14) that is different from the foot slip prevention mechanism (4) of footwear for Western-style toilets (1) of Example 1, (b) shows the state in which the foot can be slid onto the foot slip prevention mechanism (14) from the rear direction (right direction in the drawing), (c) shows the state in which the foot can be slid onto the foot slip prevention mechanism (14) from the front direction (left direction in the drawing), and (d) shows the state in which a foot slip prevention mechanism (16) that is different from the foot slip prevention mechanisms (4 and 14) is installed. The upper footwear body part (12) and the sole (13) correspond to the upper footwear body part (2) and the sole (3) of the footwear for a Western-style toilet (1) of the first embodiment.
[0034] As shown in Figure 3(a), the anti-slip mechanism (14) is fixed to both sides of the sole (13) by anti-slip mechanism fixtures (15) and is structured so that it can swing back and forth around the anti-slip mechanism fixtures (15) as fulcrums. The anti-slip mechanism fixtures (15) can be pins, screws, rivets, or a combination of bolts and nuts. Figure 3(a) shows the anti-slip mechanism (14) swinging backward with a two-dot chain line (phantom line). As shown in Fig. 3(a), the anti-slip mechanism 14, like the anti-slip mechanism 4 of the footwear for Western-style toilets 1 of Example 1, is a band-like structure having a width (length) in the front-to-back direction in plan and side views, and a semicircular arc shape extending upward from the left end to the right end in front and rear views. This band-like shape enables the anti-slip mechanism 14 to secure the foot so as to cover the instep, preventing excessive slippage of the foot. In order to fix the anti-slip mechanism (14) to both sides of the sole (13), the upper part (12) of the footwear body and the sole (13) are shaped separately. The foot slip prevention mechanism (14) can swing back and forth, so that the foot can be slid in from either the front or back, as shown in Figures 3(b) and 3(c). In addition, by swinging the foot slip prevention mechanism (14) back and forth to fit the shape of the instep, the foot can be secured so that it covers the instep, preventing excessive slippage of the foot.
[0035] As shown in Figure 3(d), two anti-slip mechanisms (16) are located on the upper part of the footwear body (12) near both ends in the front and rear directions. To use the mechanism, one is stepped on and the foot is slid onto the other. The anti-slip mechanisms (16) may be molded integrally with the upper part of the footwear body (12), or may be molded separately from the upper part of the footwear body (12) and joined by adhesive or welding.
[0036] <Use of footwear for Western-style toilets that can be used from both directions> The footwear (11) for Western-style toilets of Example 2, which can be used from both directions, can be placed on from either the front or back, regardless of the storage state after the previous use, and can be used from both directions without having to consider the storage direction after use. [Example]
[0037] <Configuration of footwear for Western-style toilets without a mechanism to prevent slippage that covers the instep> 4 is a perspective view showing footwear (21) for a Western-style toilet without a slip-prevention mechanism that covers the instep of the foot according to Example 3. (a) shows the state in which a slip-prevention mechanism (24) that does not cover the instep is installed, and (b) shows the state in which a different type of slip-prevention mechanism (25) is installed. The upper footwear body part (22) corresponds to the upper footwear body part (2) of the footwear for Western-style toilets (1) of Example 1 and the upper footwear body part (12) of the footwear for Western-style toilets (11) of Example 2. Similarly, the sole (23) corresponds to the sole (3) of the footwear for Western-style toilets (1) of Example 1 and the sole (13) of the footwear for Western-style toilets (11) of Example 2. The footwear (21) for Western-style toilets in Example 3 does not have the foot slip prevention mechanisms (4), (14), (16) that cover the instep, which are arranged in the footwear (1) for Western-style toilets in Example 1 and the footwear (11) for Western-style toilets in Example 2, and is footwear in which the foot is simply placed on the upper part of the footwear body (22).
[0038] Footwear (21) for Western-style toilets does not have anti-slip mechanisms (4, 14, 16) that cover the instep, but in order to prevent excessive slippage when the foot is placed on the upper part of the footwear (22), as shown in Figure 4(a), the upper part of the footwear (22) is provided with one or more anti-slip mechanisms (24) that have an upward convex shape that matches the shape of the sole of the foot and are used along the spaces between the toes. As shown in Figure 4(b), the upper part of the footwear (22) can also be provided with an anti-slip mechanism (25) that covers only the toes. In Figure 4(b), the area where the toes rest on the upper part of the footwear (22) covered by the anti-slip mechanism (25) is shown by a dashed line (hidden line). The shapes of the anti-slip mechanisms (24) and (25) are designed to allow for the understanding that they are capable of preventing excessive slippage while assuming (tolerating) some degree of foot slippage. In contrast, the band shapes of the anti-slip mechanisms (4), (14), and (16) are designed to allow for a clear understanding that they are capable of preventing excessive slippage while causing almost no foot slippage. In this way, the anti-slip mechanism, which is a component of footwear for Western-style toilets in this invention, may be shaped to allow for a clear understanding that it is capable of preventing excessive slippage while causing almost no foot slippage, or it may be shaped to allow for an understanding that it is capable of preventing excessive slippage while assuming (tolerating) some foot slippage.
[0039] <Using footwear for Western-style toilets that does not have a mechanism to prevent slippage and cover the top of the foot> Although footwear (21) for Western-style toilets of Example 3, which does not have a foot slip prevention mechanism covering the instep, can prevent excessive slippage of the foot when placed on it, it has less ability to follow the vertical movement of the foot itself compared to footwear (1) for Western-style toilets of Example 1 and footwear (11) for Western-style toilets of Example 2. However, in the case of an inadvertent standing-up action that does not involve walking, it is sufficient to achieve the purpose of avoiding dangers such as falling, and Western-style toilet footwear (21), which can be taken off from a seated position more easily than footwear (1) for Western-style toilets of Example 1 and footwear (11) for Western-style toilets of Example 2, can achieve this purpose, so it is not a problem even if it has less ability to follow the vertical movement of the foot itself.
[0040] The footwear for Western-style toilets (1), (11), and (21) of the present invention are a pair of footwear for use on the left and right sides when a person sits on the toilet seat, and as long as they are configured to be used when maintaining a position in which the feet are raised while sitting, they are not limited to those described in the above-mentioned embodiments of the invention, and can of course be modified in various ways within the scope of the gist of the present invention. [Industrial Applicability]
[0041] The footwear (1, 11, 21) for Western-style toilets of the present invention can be used by anyone who sits on a Western-style toilet (51), and is particularly useful for people who tend to be constipated. [Explanation of symbols]
