Description

Technical Field

[0001] The present invention relates to a wall-mounted toilet, and particularly to suppressing the scattering of urine and water containing urine around when a man urinates in a standing position, and having a function of ensuring the foot sole position at an appropriate height when sitting on the toilet seat to urinate, and relates to a toilet provided with a splash prevention mechanism.

Background Art

[0002] In general households and small-scale stores, many wall-mounted types that can be used for both defecation and urination are installed due to restrictions on the installation space of toilets. A wall-mounted toilet generally consists of a toilet body, a toilet seat on which the user sits, and a lid that is placed on the toilet and covers the upper part of the toilet seat. This type of wall-mounted toilet is used by sitting on the toilet seat except for men's urination.

[0003] Toilets widely available on the market are basically designed for use by sitting on the toilet seat. When a man uses the toilet in a standing position, the lid and the toilet seat are lifted from the toilet body, and urine is discharged aiming at the water seal accumulated on the inner bottom of the toilet body. At this time, since there is a large distance from the water seal surface, the discharged urine and the water seal containing urine scatter around, contaminating the inner and outer walls of the toilet body and its surroundings. Hereinafter, the scattering of urine and the water seal containing urine is also simply referred to as the scattering of urine.

[0004] This contamination caused by the scattering of urine becomes a source of bad odor, and the whole toilet becomes unhygienic due to the growth of various bacteria. Therefore, preventing or suppressing the scattering of urine has been regarded as an issue to be solved. Various proposals have been made as means for solving this issue. Typical examples of a number of proposals are described below.

Summary of the Invention

Problems to be Solved by the Invention

[0006] Patent Document 1 discloses an "urine splash - preventing and sit - down type toilet that can be used for both men and women" in which the height of the toilet body is adjusted to the standing position during small - scale use, and an electric lifting lift (footrest) is installed to raise the height of the user's sole when sitting on the toilet seat to ensure a proper urination posture.

[0007] The toilet disclosed in Patent Document 1 is not of a general - purpose height suitable for sitting use (not a commercially available one), so it is necessary to use a specially manufactured toilet and it cannot be applied to commercially available standard - sized toilets.

[0008] Also, Patent Document 2 discloses a splash - blocking device provided with a telescopic wall that expands and contracts in the vertical direction so as to form a substantially cylindrical wall on the opposite side of the urine - ejecting person's standing position with respect to the position of the water seal around the water seal inside the toilet body. When using the toilet seat, by performing a lifting operation to retract this telescopic wall inside the toilet body, it is possible to prevent contamination caused by urine splashing when using it in the standing position.

[0009] However, installing a telescopic wall inside the toilet body may increase the manufacturing cost, and it is expected that the cleaning work will be quite burdensome. In the technical field of the present invention, it has been an issue to realize a splash - preventing structure that is simple in structure and can be easily applied to an existing toilet body. An object of the present invention is to solve the problems in such prior art and provide a toilet equipped with a splash - preventing mechanism that can be applied without specially processing a commercially available toilet body.

Means for Solving the Problems

[0010] A typical configuration of the present invention for achieving the above object is described below. Here, for the sake of clarity in understanding the invention, reference numerals in the drawings in the following embodiments are attached to the components, but the present invention is not limited to the components indicated by these reference numerals, and it goes without saying that various modifications are possible within the scope of the technical idea of the present invention.

[0011] The present invention is a toilet provided with a splash prevention mechanism applicable to a commercially available standard toilet body, and this splash prevention mechanism is configured to be realizable by being installed between the toilet body. Its typical configuration is as follows.

[0012] A toilet 100 having a pedestal unit 200 interposed between the lower surface of the toilet body 1 constituting the toilet 100 so as to partially surround the drainage pipe 11 of the toilet 100 on the floor surface 300 where the drainage pipe 11 of the toilet 100 is installed, and is a toilet 100 provided with a splash prevention mechanism applicable to a commercially available toilet body 1. The pedestal unit 200 includes a housing 21 that receives the entire lower surface of the toilet body 1 and has a width size including the shoulder width at the standing position of the user 31 around the toilet 100 in a plan view looking at the toilet body 1 from above. Inside the housing 21, a pedestal 22 having a sole placement surface 220 that is attached to the housing 21 and holds the user's sole at a required height when sitting on the toilet seat of the toilet is installed. The pedestal 22 has a sole height change function for setting the sole position of the user 31 to a predetermined position with respect to the sole placement surface 220 both when using the toilet 100 in the standing position with the toilet seat 2 lifted and when using the toilet 100 while sitting on the toilet seat 2.

[0013] The pedestal unit 200 includes an electric retractable mechanism that stores the pedestal 22 in the housing 21 when using the toilet in the standing position of the user and pulls out the pedestal 22 from the housing 21 when using the toilet while sitting on the toilet seat 2 to raise the user's sole to an optimal height.

[0014] On the side of the housing 21 facing the user of the toilet 100, there is an opening 20 for pulling out / pushing back the footrest 22. The footrest 22 has a front plate 20a on the side facing the user 31, and a switch 23 for controlling the forward and backward movement of the electric forward and backward movement mechanism of the footrest 22 is provided on this front plate 20a. It is suitable that the switch 23 is a push switch.

[0015] Also, the toilet equipped with the splash prevention mechanism according to the present invention may have an opening 20 for pulling out / pushing back the footrest on the side of the housing 21 facing the user of the toilet 100, and a slide rail 51 may be interposed between the footrest 22 and the housing. By pushing the front surface of the footrest, the footrest 22 is configured to move forward and backward from the housing 21 by the slide rail 51.

[0016] Furthermore, the toilet equipped with the splash prevention mechanism according to the present invention may have the interior of the footrest 22 as a container for accommodating related items (toilet paper, detergent, brush, etc.) for using the toilet 100.

[0017] Also, the toilet equipped with the splash prevention mechanism according to the present invention is provided with an opening 20 for detachably attaching the footrest 22 on the side of the housing 21 facing the user 31 of the toilet 100, and the footrest 22 can be removed from the housing 21 when used in the standing position, and the footrest 22 can be attached to the housing 21 when sitting on the toilet seat 2, and the footrest 22 can be set to hold the user's sole at a height suitable for the user with respect to the sole placement surface 220.

[0018] The sole placement surface 220 of the footrest 22 is formed by partially cutting out and removing a shape that allows the user's foot in the standing position to move forward toward the housing 21 side while leaving an area for placing the user's sole when sitting, and it is possible to use it in the standing position even when the footrest 22 is attached to the housing 21.

[0019] The housing 21 is not limited to a square shape, and it may be selected in consideration of the space for placing the toilet and the overall design. However, if the footrest 22 is to be housed inside, it is necessary to consider the operability of the footrest.

[0020] In the case of the above-described device equipped with the electric advancing and retracting mechanism, the push switch 23 causes the pedestal 22 to be pulled out to a predetermined position by the first operation (first push). After use, by pushing the switch 23 again (second push), the pedestal 22 is returned (stored) inside the housing 21.

[0021] Also, in the case where a slide rail 51 is interposed between the pedestal 22 and the housing 21, the advancing and retracting mechanism of the pedestal does not use electric energy. The opening 20 provided on the side of the housing 21 facing the user of the toilet bowl is the drawer opening of the pedestal 22, and a well-known slide rail 51 is interposed between the pedestal 22 and the housing 21. With this configuration, the pedestal 22 is extended by pushing the front surface of the pedestal 22 with a finger or the like (pushing), the pedestal is pulled out from the housing 21 with a finger or the tip of the foot, and the subsequent pushing back and storage are also performed by the pushing operation of the finger or the tip of the foot.

[0022] In the present invention, the first push (first push) on the front surface of the pedestal 22 is to lightly push it with the tip of the user's foot or hand, which is a cue for pulling out the pedestal (a cue for the pulling-out operation), and the subsequent sufficient pulling out is performed with the tip of the user's foot or hand. And the storage into the housing 21 after use is pushed in by the next push (second push) with the tip of the user's foot or hand.

[0023] In the configuration where the pedestal 22 is accommodated inside the housing 21, since there is a drain pipe 11 inside the housing 21, the shapes and arrangements of the housing 21 and the pedestal 22 are considered in view of this.

[0024] In addition to adopting electric mechanisms such as solenoids, electric gears, and linear motors for the advancing and retracting mechanism 240 of the pedestal 22, non-electric mechanisms such as a slide rail mechanism or a manual pulling-out structure using simple wheels or rollers can also be adopted. A representative example thereof is a slide rail mechanism.

[0025] As described above, in the case where a solenoid is used as an electric mechanism for the advancing and retracting mechanism 240 for taking the pedestal 22 in and out of the housing 21, a push switch provided on the front surface of the pedestal 22 is pushed (first push) by the user to drive the solenoid 24 to pull it out, and after the pedestal 22 is used, it is controlled to be stored inside the housing 21 by the next push (second push). The expansion and contraction direction is indicated by the thick arrow A in FIG. 1. The power supply and the control device are not shown.

[0026] When the pedestal 22 is configured by the advancing and retracting mechanism 240, the user sitting on the toilet seat 2 can pull out the pedestal 22 from the housing 21 by, for example, pressing the switch 23 with the toes (first push) before use, and then sit backward. After use, the user can get off the toilet seat and store the pedestal 22 in the housing 21 by pressing the switch 23 with the toes again (second push), and this operation can facilitate the operation of the pedestal 22 without bending the body. Needless to say, the user may operate the switch 23 with the fingertips (fingers).

[0027] The pedestal 22 according to the present invention can be easily implemented for a commercially available or existing toilet during the installation or renovation of the toilet, so that the installation cost can be saved with a slight increase in the working cost.

[0028] Furthermore, in the electric advancing and retracting mechanism 240, the mechanism for causing the pedestal 22 to advance and retract may employ a rack and pinion mechanism using an electric motor or a linear motor mechanism used for an automatic door or the like.

[0029] Further, even if the pedestal is moved forward and backward without using electric energy, for example, a slide rail mechanism can be used. The slide rail mechanism is widely used as a pull-out / push-back mechanism for trays (drawers) in office equipment and various storage devices. For example, by gently pushing the front plate of the tray in a copying machine, the tray can be pulled out (a clue for the pull-out operation), and then it can be gently pulled out with a fingertip or the like. Also in the present invention, the pedestal can be moved forward and backward by gently pushing the front plate.

[0030] Furthermore, in the present invention, a configuration can also be adopted in which a slide rail is interposed between the pedestal 22 and the housing 21, and by pushing the front surface (front plate) of the pedestal 22, the pedestal can be pulled out from the housing 21. The slide rail is installed between the inner side wall of the housing and the pedestal 22, or between the floor surface 300 and the pedestal 22. In the case of a housing having a bottom plate, it is installed between the bottom plate and the pedestal.

[0031] In the case of using the slide rail mechanism, after the pedestal 22 is used, it can be configured to be stored in the housing 21 by pushing its front plate. In this configuration, since an electric mechanism is not required, the energy saving effect is significant. Wheels 25 or rollers can be provided on the bottom surface of the pedestal 22 to facilitate movement on the floor surface 300 or on the bottom surface of the housing. A roller-type slide rail having rollers at its ends may be used, and it can be appropriately selected according to the use environment.

[0032] Also, since the inside of the pedestal 22 is a space, a secondary effect can be expected that the inside of the toilet can be tidied up by using it as a storage for toilet paper or the like.

[0033] An opening 20 is provided on the side of the housing 21 facing the user 31 of the toilet 100 for detachably attaching the footrest 22. When in the standing position, the footrest 22 can be removed from the housing 21, and when sitting on the toilet seat 2, the footrest 22 can be attached to the housing 21 and the user's sole can be held at a height suitable for the user with respect to the sole placement surface 220. The overall structure can be simple and easily installed.

[0034] Furthermore, a part of the sole placement surface 220 of the footrest 22 is cut out and removed to form a shape that allows the user's 31 foot to move forward toward the housing 21 side in the standing position while leaving an area for placing the user's 31 sole when sitting. Even when the footrest 22 is attached to the housing 21, it is possible to use it in the standing position without the need to remove the footrest 22 from the housing 21 when using it in the standing position. Since it is possible to use it in the standing position with the footrest 22 still attached to the housing 21, the user does not need to perform any operations when using it and can use it cleanly.

Advantages of the Invention

[0035] According to the toilet provided with the splash prevention mechanism according to the present invention, it is possible to suppress the scattering of urine and the water seal containing urine when a man urinates in the standing position, and it also has a function of ensuring the proper height of the sole position when sitting on the toilet seat. Therefore, the feet can maintain a stable state even when using it while sitting. And the toilet provided with the splash prevention mechanism according to the present invention can be applied without specially processing a commercially available toilet body. Therefore, there is no need to prepare a toilet with a special shape, and it can be easily and inexpensively installed not only during new construction but also during renovation.

Best Mode for Carrying Out the Invention

[0037] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings of the examples.

Example

[0038] FIG. 1 is an overall perspective view for explaining Example 1 of a toilet provided with a splash prevention mechanism according to the present invention, FIG. 2 is a plan view of the toilet body of FIG. 1 as viewed from above, in which (a) of the figure shows a state where the pedestal is housed in the housing, and (b) of the figure shows a state where the pedestal is pulled out from the housing. Further, FIG. 3 shows a partially cut-away (a) side view and (b) plan view for explaining the state of use in the standing position, and FIG. 4 shows a partially cut-away (a) side view and (b) plan view for explaining the state of use in the sitting position. The pedestal unit 200 is composed of a rectangular housing 21 having a width size W including the shoulder width of the user 31 in the standing position around the toilet 100. L is the depth size for holding the toilet 100 in a stable posture, H is the height from the floor surface, a height suitable for use in the standing position (standing posture), and a size for holding the soles of the feet of the user sitting on the toilet seat at a predetermined height (the position of the average sole of the user).

[0039] In FIGS. 1 to 4, the toilet 100 is a general toilet composed of a toilet body 1, a toilet seat 2, and a lid 3, and is installed on the floor surface 300 via a pedestal unit 200. A drain pipe 11 communicating with the toilet body 1 is installed on the floor surface 300.

[0040] In Example 1, the pedestal unit 200 is composed of a housing 21 and a pedestal 22 that is retractably housed inside the housing 21. On the floor surface 300 where the drain pipe 11 of the toilet 100 is installed, the pedestal unit 200 is housed except for the side opposite to the user side of the drain pipe 11, and is provided with a splash prevention mechanism applicable to a commercially available toilet body 1.

[0041] The housing 21 that constitutes the footrest unit 200 is made of a material with high strength sufficient to support the weight of the user sitting on the toilet 100. For example, high-tensile steel plate (commonly known as high-tensile steel) is suitable, but it can also be hard wood. The footrest 22 that is retractably housed inside the housing 21 is also preferably made of the same material, or wood, or a high-strength resin material such as ABS (acrylonitrile-butadiene-styrene) or PC (polycarbonate), and can be an injection-molded product of synthetic resin.

[0042] In addition, the footrest unit 200 can also be shaped to reach the rear end position of the housing 21 in a U-shape that opens at the rear end of the housing 21 except for a part on the side opposite to the user's side. By making it U-shaped, the depth size of the footrest can be increased. The footrest unit 200 has a rectangular housing 21 that receives the entire lower surface of the toilet body 1 and has a width size W including the shoulder width at the standing position of the user 31 around the toilet 100 in a plan view seen from above the toilet body 1.

[0043] As shown in FIG. 3, in the first embodiment, inside the housing 21, when using the toilet body 1 in the standing position with the toilet seat 2 of the toilet 100 raised, it is housed inside the housing 21, and when using it in the sitting position on the toilet seat 2 of the toilet 100 shown in FIG. 4, a footrest 22 is housed that extends from inside the housing 21 and is provided with an electric retractable mechanism 240 for holding the soles 32 of the user 31 at a required height.

[0044] This footrest 22 is box-shaped with a rear edge on the user 31 side of the drainage pipe 11, and a pair of retractable mechanisms 240 are provided on the back side (right side in the drawing of FIG. 3) of the footrest 22. In this configuration example, solenoids 24a and 24b are used as the retractable mechanisms 240. FIG. 3(a) shows a state where the footrest 22 is housed inside the housing 21. FIG. 3(b) is a top view thereof, and the solenoids 24a and 24b are installed on the lines A - A' and B - B' in the drawing.

[0045] When the solenoids 24a and 24b extend, the footrest 22 moves on the floor surface 300 by the wheels 25 provided at its bottom. Although FIG. 3 shows the bottom surface of the housing 21 being open to facilitate smooth wheel movement, this bottom surface may be closed with a plate. In that case, the provided plate can be made thin or extended to the position where the user's feet are placed to enable the wheels 25 to rotate smoothly.

[0046] FIG. 5 is a plan view for explaining an example of the retractable mechanism 240 for pulling the footrest 22 out of the housing 21 and storing it in its original position. Inside the housing 21, as an example of the retractable mechanism 240 for moving the footrest 22 stored in the space on the user side (the left side in the drawing of FIG. 5) of the drainage pipe 11, an example using a pair of solenoids 24a and 24b is shown. The structure cross-sectioned along the line C - C' in FIG. 5 corresponds to FIG. 3(a). The drainage pipe is not shown in FIG. 3(a). The solenoids 24a and 24b are arranged at the positions of the lines A - A' and B - B' in FIG. 3(b) (see FIG. 5).

[0047] Also, FIG. 5 shows the state of FIG. 2(a) where the footrest 22 is stored inside the housing 21. By first pushing the switch 23 provided on the open end side of the housing 21 to extend the pair of solenoids 24a and 24b in parallel, the footrest 22 is pulled out of the housing 21 as shown in FIG. 2(b) and moved to the position to serve as a footrest for the user. By pushing the switch 23 again (second push), the footrest 22 is returned into the housing 21.

[0048] FIG. 6 is an explanatory view of another example of the retractable mechanism 240 for pulling the footrest 22 out of the housing 21 and returning it to its original position for storage. In this example, the footrest unit 200 is formed in a U-shape that opens at the rear end of the housing 21, excluding a part on the side opposite to the user side at the position of the drainage pipe 11, and the other part is shaped to reach the rear end position of the housing 21.

[0049] Racks 28a and 28b are provided opposite to the U-shaped inner wall of FIG. 6, and are configured to be driven by pinions 27a and 27b driven by the gear 26 of the electric motor. Note that an intermediate gear 27c is interposed between one of the pinions 27a and 27b to make the moving directions of the racks 28a and 28b the same. Naturally, the number of teeth of each gear and the rack is set so that the racks 28a and 28b are the same and move at the same speed.

[0050] With the configuration shown in FIG. 6, the base 22 can be stably pulled out / pushed in and stopped at a predetermined position, and as will be described later, effective space utilization of the base 22 becomes possible.

[0051] Returning to FIG. 1, the use of the base 22 as a storage will be described. The inside of the base 22 is a space. Using this space, it can be used as a storage container for toilet supplies, such as toilet paper and deodorants. In FIG. 1, a front plate 20a is provided at the opening of the base 22, and two drawer containers 41 are stored inside. A handle 42 is provided on the drawer container 41, and the drawer container 41 can be pulled forward by the handle. With this configuration, the toilet room can be tidied up, and a clean toilet space can be realized.

[0052] FIG. 7 is an explanatory diagram of still another example of the advancing / retreating mechanism 240 for setting the base 22. In this configuration example, a footrest 22' is rotatably attached to the opening 20 of the base 22 shown in FIG. 7(a) by a hinge 29 to the footrest position. The rotation operation is performed by the rod 24' of the solenoid 24. The rod 24' and the footrest 22' are connected by a support bar 24", and the rod 24' extends to the left in the figure. As shown in FIG. 7(b), the support bar 24" bends about 90 degrees with respect to the rod 24' at the position where the footrest 22' is horizontal, and holds the footrest 22' on the floor surface 300.

[0053] The setting mechanism of the pedestal 22 composed of the solenoid 24, the rod 24', and the support bar 24" shown in Fig. 7 may be one set, but it is desirable to install a pair on both sides sandwiching the drain pipe 11 of the housing 21 shown in Fig. 5. Fig. 7 shows the case where a pair is installed on both sides sandwiching the drain pipe 11 of the housing 21.

[0054] By adopting the advancing and retreating mechanism 240 shown in Fig. 7, a simple and inexpensive pedestal 22 can be configured. Repeating, for the inserting and extracting mechanism of the pedestal 22, the motor / gear mechanism described in Fig. 6 and other known moving means can be used. In addition, in this configuration example as well, since the inside of the housing 1 can be used as a storage space, the toilet room can be tidied up in the same way as described in Fig. 1 and the like, and a clean toilet space can be realized.

[0055] The advancing and retreating mechanism 240 adopted in the present invention is not limited to the above-described configuration mechanism, and a rod expansion and contraction mechanism using a fluid such as hydraulic pressure or gas (air), a screw bar mechanism, a slide rail mechanism described below, etc. can also be adopted.

Embodiment

[0056] Fig. 8 is a (a) side view and (b) plan view showing a broken-away view of the main part of an example of Embodiment 2 of a toilet bowl equipped with the splash prevention mechanism according to the present invention. It is an example of an advancing and retreating mechanism that does not use electrical energy to pull out the pedestal from the housing and store it in the original position. The broken line in the figure indicates the state (reference numeral 22') where the pedestal is pulled out from the housing. The dotted arrow indicates the pulling-out direction.

[0057] In the configuration of this Embodiment 2, on the side of the housing 21 facing the user 31 of the toilet bowl, there is an opening 20 which is the pulling-out port of the pedestal 22. A slide rail 51 is interposed between the pedestal 22 and the housing 21. This slide rail 51 is called a side type.

[0058] A variety of forms of slide rails 51 are known, and their structures are known. The general structure of a typical example thereof is composed of an outer member 51a having a long C-shaped cross section and an inner member 51b having the same long C shape and incorporated inside the outer member 51a with bearings.

[0059] In Fig. 8, the outer member 51a is fixed to the inner side wall of the housing 21, and the inner member 51b is attached to the side surface of the pedestal 22 and the two are combined so that the pedestal 22 can be taken in and out through the opening 20 of the housing 21 as shown in Fig. 8. In Fig. 8(a), small wheels 25 are attached to the bottom surface of the pedestal 22 so that the pedestal 22 can move smoothly on the floor surface 300. Alternatively, a roller type slide rail having small rollers (wheels) attached to the tip (opening 20 side) of the inner member 51b may be attached to the lower side of the side surface or the bottom surface of the pedestal 22. Fig. 9 described later shows a configuration example in which a slide rail is attached to the bottom surface of the pedestal 22.

[0060] In this configuration, the pedestal 22 is pulled out from the housing 21 by pushing the front surface (front plate) of the pedestal 22 with a finger or a toe, and the subsequent pushing back and storing are also performed with a finger or a toe. The first push (first push) of the front surface of the pedestal here is a head-out (starting point for pulling out) that is lightly pushed with the user's toe or fingertip, and the subsequent sufficient pulling out is performed with the user's fingertip or toe. The storage of the pedestal 22 into the housing 21 after use is performed by the next push (second push) with the user's toe or fingertip.

[0061] Fig. 9 is an explanatory view of the configuration of another example of a retracting mechanism that does not use electric energy for pulling the pedestal out of the housing and storing it in the original position. Fig. 9(a) is a side view showing the main part broken, and Fig. 9(b) is a plan view of the main part for explaining the retraction of the pedestal stored in the housing. The broken line in Fig. 9 indicates the state (reference numeral 22') in which the pedestal 22 is pulled out from the housing 21. Similar to Fig. 8, the dotted arrow indicates the pulling out direction. In this configuration example, a pair of slide rails 51 are attached to the bottom surface of the pedestal 22.

[0062] Also, in order to efficiently utilize the storage function of the pedestal 22 with respect to the internal volume of the housing 21, it is different from FIG. 8 in that it is concave in plan view (the same as the U-shape in FIG. 6) so as to be able to advance and retreat while avoiding the drain pipe 11. The slide rail 51 attached to the pedestal 22 in FIG. 9 is of the under type and is of the roller type having wheels 25 on the opening 20 side. Instead of using this roller type, separate wheels can be attached to the tip position. When it is not desired for the pedestal 22 to move directly on the floor surface 300, a bottom plate can be attached to the housing 21, or a thin plate for movement (not shown) can be installed on the floor surface 300. By appropriately extending the thin plate from the opening 20 of the housing 21 to the user side, the pedestal 22 can be smoothly moved.

[0063] In this configuration example, after the pedestal 22 is used, its front plate is pushed in with the toes or fingertips and stored in the housing. Since this configuration also does not require an electric mechanism as in the configuration example described with FIG. 8, the energy saving effect is large.

[0064] FIG. 10 is an overall perspective view for explaining an example of Example 3 of a toilet bowl provided with a splash prevention mechanism according to the present invention, and shows a configuration in which a detachable pedestal is attached to a housing. Also in this example, the toilet bowl 100 is the same as each of the above examples. In Example 3, the housing 21 constituting the pedestal unit 200 mainly functions as a pedestal set to a height suitable for use of the toilet bowl 100 in a standing position. A sole placement surface 220 for placing the soles of the feet of a user sitting on the toilet seat 2 is detachably coupled to an opening 20 at an end of the housing 21 facing the toilet user (the front end on the left side toward the paper surface of the figure).

[0065] In the pedestal 22 of this example, supports 221a and 221b are formed in parallel on both lower sides of the sole placement surface 220 which is a flat plate portion for placing the soles of the feet of the user. The configuration of the other toilet 100 and the size (W, L, H) of the housing are the same as those in the first embodiment described with reference to FIG. 1. The material of the pedestal 22 of this embodiment with the housing 21 is the same as that in the first and second embodiments. However, considering the touch feeling against the user's sole for the pedestal 22, it is desirable to use wood or ABS. In this embodiment, it is made of an integrally molded ABS product. Note that it is also desirable to adopt ABS in each of the above embodiments.

[0066] FIG. 11 is a (a) state diagram of the process of attaching the detachable pedestal to the housing for further explaining the third embodiment shown in FIG. 10, and (b) a plan view of the attached state. On the surface of the pedestal 22, locking protrusions 230a and 230b are provided on both sides of the end facing the housing 21 on the flat sole placement surface 220. On the inner end of the opening 20 of the housing 21, locking protrusion receivers 231a and 231b for receiving the locking protrusions 230a and 230b are provided.

[0067] Insert the pedestal 22 into the opening 20 of the housing 21 along the arrow shown in FIG. 11(a), and integrate the pedestal 22 with the housing 21 by coupling the locking protrusions 230a and 230b to the locking protrusion receivers 231a and 231b. FIG. 11(b) shows the state where the pedestal 22 is integrated with the housing 21.

[0068] FIG. 12 is an explanatory diagram of a configuration example in which the locking protrusions 230a and 230b of the pedestal 22 are coupled to the locking protrusion receivers 231a and 231b of the housing 21. If the locking protrusions 230a and 230b of the pedestal 22 are simply coupled to the locking protrusion receivers 231a and 231b, depending on the movement of the user's foot, the coupling may become loose, causing uneasiness to the user, or there is a risk that the coupling may come off.

[0069] In order to avoid the occurrence of such events, it is also conceivable to firmly fit the locking protrusions 230a and 230b to the locking protrusion receivers 231a and 231b. However, since this coupling is for easy attachment and detachment, a strong coupling is not preferable.

[0070] In this embodiment, as shown in FIG. 12, locking projection receivers 231a and 231b are attached to the ceiling side of the opening 20 of the housing 21, and locking projections 230a and 230b are attached to the housing-side end portions of the base 22. As shown in FIG. 12, the housing-side end portions of the base 22 are obliquely inserted into the opening 20 of the housing 21 above the floor surface 300, and the housing-side end portions of the base 22 are moved as shown by arrows A and B to bring them closer to the ceiling side of the opening 20 of the housing 21, and the locking projections 230a and 230b are coupled to the locking projection receivers 231a and 231b.

[0071] The lower ends of the portions of the support plates 221a and 221b of the base 22 close to the housing 21 have convex portions 223a and 223b. In a state where the convex portions 223a and 223b are in contact with the floor surface 300, the locking projections 230a and 230b are engaged with the locking projection receivers 231a and 231b.

[0072] In this initial locked state, the support plates 221a and 221b of the base 22 are formed such that the lower ends of the end portions far from the housing 21 are slightly separated from the surface SL in contact with the floor by a gap d. This gap d is set to be zero when the user is on the base 22 or when the user is seated on the toilet seat and places their feet on it, so that the convex portions 223a and 223b further press the floor surface. When the support plates 221a and 221b of the base 22 are in close contact with the floor surface due to the weight of the user or the weight of the footrest, the base 22 is prevented from moving inadvertently. When the load applied by the user is removed, the base 22 can be easily removed from the housing 21.

[0073] That is, by adopting the structure of coupling the base 22 and the housing 21 as described above, the coupling of the locking projections 230a and 230b and the locking projection receivers 231a and 231b can be moved in a direction opposite to the arrows A and B shown in FIG. 11(c), and the base 22 can be easily separated from the housing 21. Note that the configuration shown in FIG. 12 is an example, and if there are other such coupling means, they can also be adopted.

[0074] FIG. 13 is a plan view for explaining various types of pedestals that can be adopted in the third embodiment shown in FIG. 10, and reference numeral 220 indicates the sole placement surface. In FIG. 13(a), it is a type suitable for users with a large foot width or a women - priority toilet. It is widened to about the width W1 of the area extending from the sole placement surface 220 at the center to the user side. In the standing posture, the user straddles the portion of this width W1 for use. When sitting on the toilet seat, the feet are placed on the wide central portion.

[0075] FIG. 13(b) is a standard type that can be used for both men, women, and children. Also, FIG. 13(c) is a type suitable for users with a narrow foot width or a men - priority toilet. The width W2 of the area extending from the sole placement surface 220 at the center to the user side is narrow, and in the standing posture, both feet are positioned on the constricted portion. When used in the sitting position, the feet are placed on the portions that protrude to the left and right.

[0076] FIG. 13(d) is a type suitable for users with an even narrower foot width or a children - priority toilet. Both feet can be inserted into the cut - out portion at the center for use in the standing posture. When used in the sitting position, the feet can be freely placed on the portions other than the cut - out portion.

[0077] Any type of pedestal shown in FIG. 13 is intended for use in a state of being coupled to the housing.

Embodiment

[0078] FIG. 14 is an overall perspective view for explaining an example of the fourth embodiment of a toilet equipped with a splash - prevention mechanism according to the present invention, and it is a view showing a configuration in which a detachable pedestal is attached to the housing. FIG. 15 is an explanatory view of a configuration example in which a locking projection of the pedestal is coupled to a locking hole of the housing in the fourth embodiment shown in FIG. 14. Also in this embodiment, the toilet 100 is the same as each of the above - mentioned embodiments. In the fourth embodiment, the housing 21 that constitutes the pedestal unit 200 mainly functions as a pedestal that sets the toilet 100 to a height suitable for use in the standing position. At the opening 20 at the end of the housing 21 facing the toilet user, a sole placement surface 220 for placing the soles of the feet of the user sitting on the toilet seat 2 is detachably coupled.

[0079] In the pedestal 22 of this Example 4, support bodies 221c, 221c are formed in parallel on both lower sides of the sole placement surface 220 which is a flat plate portion for placing the soles of the feet of the user. The configurations of the other toilet 100 and the size (W, L, H) of the housing are the same as those of Example 1 described with reference to FIG. 1. The material of the pedestal 22 of this example with respect to the housing 21 is the same as that of Example 3, and it is desirable to use wood or ABS. In this example, it is formed of wood.

[0080] FIG. 15 is an explanatory view of a configuration example in which a locking projection 250 of the pedestal 22 is fitted into a locking hole 251 formed in the housing 21. In this Example 4, a notch is provided in the ceiling surface of the opening 20 of the housing 21 by an amount corresponding to the thickness of the pedestal 22 to form a step, and a locking hole 251 is drilled. Then, a locking projection 250 is provided at the housing-side end of the pedestal 22. As shown in FIG. 15, the housing-side end of the pedestal 22 is placed on the step of the ceiling surface in the opening 20 of the housing 21 from above, the locking projection 250 is fitted into the locking hole 251, and the housing 21 and the pedestal 22 are connected.

[0081] Also, the shape of the pedestal 22 can adopt various shapes as shown in FIG. 13. Also in Example 4, by configuring the sole placement surface 220 of the pedestal 22 such that a part thereof is cut out and removed in a shape that allows the position of the user's feet in the standing position to be advanced toward the housing 21 side and leaves a region for placing the soles of the feet of the user during sitting use, it is possible to use the toilet in the standing position even when the pedestal 22 is attached to the housing 21. Further, by disposing a support plate 221 on the lower surface of the portion that leaves the region for placing the soles as shown in FIG. 13, the strength can be further increased. With the configuration shown in Example 4, there is no step at the connection portion between the housing 21 and the pedestal 22, and connection can be achieved only by fitting the locking projection 250 from above, so the attachment is simple and the detachment is also easy.
