Description

[Technical Field]

[0001] The present invention relates to a toilet seat attachment for attaching a toilet seat device to a toilet bowl, and more particularly to a toilet seat attachment that allows a toilet seat device to be attached to various types of toilet bowls. [Background technology]

[0002] Conventionally, toilet seat devices with flushing functions are fixed to a Western-style toilet bowl via a fixing plate. The fixing method involves aligning a pair of bolt holes in the fixing plate with a pair of fixing holes formed in the rear of the toilet bowl, inserting fixing bolts into the bolt holes and fixing holes, and tightening them with nuts. Of the above, the spacing between the pair of fixing holes in a toilet is standardized by a standard, so it has generally been possible to retrofit various types of toilet seat devices to existing toilets. However, for example, if the toilet is made in a foreign country, the intervals between the fixing holes are wide, making it difficult to retrofit the toilet seat device. Therefore, in recent years, a technology has been developed that allows a toilet seat device to be retrofitted to a toilet bowl having different intervals between the fixing holes, and a related idea has already been disclosed.

[0003] Patent Document 1 discloses an idea for a toilet seat with a flushing function that can be attached to toilets of different sizes and types, under the title "Toilet Seat with Washing Function." The device disclosed in Patent Document 1 is a toilet seat with a flushing function that is composed of a toilet seat, a toilet seat cover, and a connector that attaches the toilet seat to the toilet bowl. The connector includes a connection part, an adjustable connecting plug and a nut on the underside of the connecting part, and the connecting part has a wedge-shaped groove on its underside. The connecting plug is characterized by having a disk-shaped member, an adapter that protrudes upward from near the periphery of the disk-shaped member and engages with the wedge-shaped groove, and a threaded part that protrudes downward from the disk-shaped member and has a lower end onto which a nut is screwed. In this device, the adapter engages with the wedge-shaped groove and moves back and forth along the wedge-shaped groove. The adapter also rotates eccentrically because it protrudes from the periphery of the disc-shaped member. This allows the threaded portion of the connecting plug to be inserted into the mounting holes with various intervals, making it possible to mount the toilet seat on toilets of different sizes and types.

[0004] [Patent Document 1] Utility Model Registration No. 3057253 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the device disclosed in Patent Document 1 requires the installation of a new flushing toilet seat with a connector, making it impossible to attach a different toilet seat device to an existing toilet seat. This means that it may not be possible to install the desired toilet seat device. Furthermore, even if an existing toilet seat device is modified to add a connector, the modification process requires additional costs and effort. Furthermore, foreign-made toilets have a variety of differences in size from front to back, and the shape of the top surface of the toilet bowl varies in addition to the distance between the fixing holes. Therefore, in the design of Patent Document 1, there are parts where the toilet bowl lifts up from the top surface of the toilet seat, which may cause localized excess weight on the toilet seat or cause it to wobble when a user sits on it.

[0006] The present invention was made in response to such conventional circumstances, and aims to provide a toilet seat attachment that can be attached to various types of toilets without modifying the desired toilet seat device, and that can stably fix the toilet seat device to the toilet. [Means for solving the problem]

[0007] In order to achieve the above object, the first invention comprises a base plate attached to a fixing plate that fixes a casing constituting a toilet seat device to the toilet bowl and positioned between the fixing plate and the toilet bowl, and one or more pairs of first mounting members that attach the base plate to the fixing plate, wherein the fixing plate has a pair of retaining holes for inserting and holding a pair of fixing members that are inserted into a pair of pre-existing fixing holes provided at the rear of the toilet bowl, and the base plate is characterized in that a first locking portion is formed on the upper surface of the base plate and a pair of insertion holes for inserting the pair of fixing members are formed through the base plate, and the upper end of the first mounting member is locked in the retaining hole and the lower end of the first mounting member is locked in the first locking portion.

[0008] In the invention having such a configuration, the toilet seat device includes at least a toilet seat to be placed on the toilet bowl, and a casing provided with an opening / closing structure for holding the toilet seat so that it can be opened and closed. The casing may or may not have a built-in cleaning device consisting of a nozzle, electronic components, etc. The fixing plate is a plate-like member fixed to the bottom surface of the casing. The holding hole of the fixing plate is elongated along the depth direction of the fixing plate so that the casing can be fixed so as to be movable in the front-to-rear direction of the toilet seat. A screw is used as the fixing member.

[0009] The base plate is a generally rectangular plate that is fixed to the underside of the fixing plate via the first mounting member. The distance between the pair of insertion holes formed in the base plate is equal to the distance between the fixing holes. This is because the pair of insertion holes are provided to receive a pair of fixing members that are inserted into a pair of fixing holes provided in the toilet. Next, the first mounting member may have a shape that allows it to be locked or fitted into the retaining hole. Specifically, the cross section along the thickness direction of the first mounting member in the width direction of the retaining hole may have a tapered shape that narrows from the upper end to the lower end of the first mounting member, or symmetrically opposing sides of this tapered shape may have a stepped shape. Furthermore, when the retaining holes of the fixing plate are formed elongated along the depth direction of the fixing plate, the first attachment members can be disposed at any position in the depth direction of the retaining holes. Furthermore, the number of first attachment members per retaining hole may be one or more.

[0010] The first locking portion has a shape that corresponds to the shape of the lower end of the first mounting member.Furthermore, it is desirable that the first locking portion has a shape that prevents the base plate from easily falling off the fixing plate.

[0011] In the invention having the above configuration, the distance between the insertion holes in the base plate is equal to the distance between the fixing holes in the toilet, so when a pair of fixing members are inserted into a pair of insertion holes, the pair of fixing members are easily inserted into a pair of fixing holes. Therefore, the base plate is attached to the underside of the fixing plate via the first attachment member, and the fixing member is then inserted into the insertion hole and the fixing hole and fixed, thereby attaching the toilet seat device to the toilet bowl.

[0012] The second invention is characterized in that, in the first invention, the first engagement portion is a groove portion, and the groove portion is provided along the depth direction of the base plate, which coincides with the front-to-back direction of the toilet bowl. In the invention having this configuration, in addition to the effects of the first invention, the first locking portion to which the lower end of the first mounting member is locked is a groove portion, so that the first mounting member can slide along the depth direction of the base plate, and therefore the position of the fixing plate relative to the base plate can be changed in the depth direction of the base plate.

[0013] The third invention is characterized in that, in the first or second invention, it is arranged between the base plate and the toilet bowl and includes a support member that supports the base plate, the base plate has a second engagement portion formed on the underside of the base plate, and the support member has its upper end engaged with the second engagement portion.

[0014] In the invention configured as described above, the upper end of the support member is engaged with the second engaging portion formed on the underside of the base plate, so that the support member is positioned between the underside of the base plate and the upper end surface of the rear of the toilet seat. Also, the support member may have a cross section along the thickness direction of the support member in the width direction of the base plate, which is tapered, for example, widening from the upper end to the lower end, or the symmetrically opposing sides of this tapered shape may be stepped. Furthermore, the support member may have an outer edge that is trapezoidal or rectangular when viewed from the side. The number of support members may be one or more.

[0015] Next, the second locking portion may be, for example, a groove provided along the depth direction of the base plate, or may be a plurality of recesses provided at intervals along the depth direction of the base plate, thereby changing the position of the support member relative to the base plate in the depth direction of the base plate. The second locking portion has a shape that corresponds to the shape of the upper end of the support member.Furthermore, it is desirable that the second locking portion has a shape that prevents the support member from easily falling off the base plate. In the invention having the above configuration, in addition to the effects of the first or second invention, the support member prevents, for example, interference between the nozzle cover and the toilet bowl. Furthermore, the toilet seat can be tilted so that any point on the underside of the toilet seat abuts the top of the toilet bowl. The tilt of the toilet seat can be adjusted by increasing or decreasing the thickness and number of the support members, as well as by changing the position of the support members relative to the second locking portion.

[0016] The fourth invention is characterized in that, in the first or second invention, a second mounting member is provided instead of the first mounting member, and the second mounting member has an upper end engaged with the retaining hole and an mounting insertion hole for inserting the fixing member formed through the second mounting member. In an invention having such a configuration, the toilet seat device is attached to the toilet seat by aligning the mounting insertion hole of the second mounting member engaged with the retaining hole, the insertion hole of the base plate, and the fixing hole of the toilet, and inserting the fixing member through them.

[0017] In the first or second invention, the base plate is attached to the fixed plate via the first locking portion. In contrast, in the third invention, the lower end of the second mounting member is not locked to the first locking portion of the base plate, so the base plate is attached to the fixed plate by the mounting insertion hole of the second mounting member and the fixing member. Furthermore, when the retaining hole of the fixing plate is formed elongated along the depth direction of the fixing plate, the second mounting member can be disposed at any position in the depth direction of the retaining hole.Other than this, the operation of the fourth invention is the same as that of the first or second invention.

[0018] The fifth invention is characterized in that, in the fourth invention, a lift member is provided on the back surface of the toilet seat that is attached to an existing cushion, and the lift member supports the toilet seat by abutting its outer bottom surface against the upper surface of the toilet bowl. In the invention with this configuration, as mentioned above, the provision of a base plate may cause the entire or part of the underside of the toilet seat to lift up from the toilet seat. Therefore, if a lift member is attached to a cushion located near the lifted area, the outer bottom surface of the support member will come into contact with the upper end surface of the toilet seat when the toilet seat is tilted down so that it can be sat on, and the toilet seat will be supported by the lift member. In the invention of the above configuration, in addition to the fourth invention, the toilet seat is supported by a lift member, so that when a user sits on it, localized excessive weight is less likely to be applied to the toilet seat, thereby preventing damage or rattling due to excessive bending of the toilet seat. [Effects of the Invention]

[0019] According to the first aspect of the present invention, the toilet seat device can be easily attached to the toilet bowl via the base plate, the first attachment member, and the existing fixing plate. In other words, there is no need to modify the existing toilet seat device, so there is no need to incur the cost or effort required for modification. In addition, according to the first aspect of the invention, the spacing between the insertion holes in the base plate is the same as the spacing between the fixing holes in the toilet, so the base plate can be securely attached to the toilet. Also, even if the spacing between the fixing holes varies, the spacing between the insertion holes can be designed accordingly, so the base plate can be attached to various types of toilets. Furthermore, since the fixing plate is attached to the base plate via the first locking portion, the desired toilet seat device can be attached to an existing toilet bowl.

[0020] According to the second aspect of the invention, in addition to the effects of the first aspect, the first locking portion allows the position of the fixing plate to be changed in the depth direction of the base plate, so the position of the toilet seat device can be adjusted in the front-to-rear direction of the toilet. Furthermore, the lower end of the first mounting member can be easily slid along the first locking portion. Therefore, the toilet seat device can be attached to various types of toilets in detail, providing good versatility.

[0021] According to the third invention, in addition to the effects of the first or second invention, the support member can prevent interference caused by attaching the toilet seat attachment and create a point where the toilet seat abuts against the toilet bowl, thus not impeding the function of the toilet seat device before the toilet seat attachment is attached and improving stability when the user sits on the toilet seat.

[0022] According to the fourth invention, in addition to the effects of the first or second invention, the toilet seat device can be attached to the toilet by inserting a fixing member into the mounting insertion hole or the like of the second mounting member, thereby achieving the same effects as those of the first invention. Furthermore, when the second mounting member is positioned at any position in the depth direction of the retaining hole, the position of the fixing plate relative to the base plate can be changed in the depth direction of the base plate. Therefore, in this case, the fourth aspect of the invention can achieve the same effect as the second aspect of the invention.

[0023] According to the fifth invention, in addition to the effects of the fourth invention, the lift member prevents damage to the toilet seat due to bending, and also makes it possible to prevent unexpected shaking when a user sits on the toilet seat. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION [Example]

[0025] A toilet seat attachment according to an embodiment of the present invention will be described in detail with reference to Figures 1 to 13. Figure 1 is an exploded perspective view of the toilet seat attachment according to the embodiment. As shown in Figure 1, the toilet seat attachment 1 according to the embodiment is a device for attaching a cleansing toilet seat device to a toilet 60, and comprises a base plate 2, a plurality of first attachment members 3, and a plurality of support members 4 and 5. Note that the cleansing toilet seat device and the toilet 60 are existing devices and are not included in the invention of this application. Of the toilet seat attachment 1, the base plate 2 is attached to the fixed plate 53. The first mounting member 3 is a member for fixing the base plate 2 to the fixed plate 53, and is positioned above the fixed plate 53. The support members 4 and 5 are members for lifting and supporting the base plate 2 from the toilet bowl 60, and are positioned between the base plate 2 and the toilet bowl 60. The base plate 2, the first mounting member 3, and the support members 4 and 5 are made of, for example, resin, and are manufactured using a 3D printer.

[0026] Next, a brief description of the cleansing toilet seat device will be given. The cleansing toilet seat device 50 (see FIGS. 8 and 9) comprises a casing 51 that houses a cleaning device (not shown), and a toilet seat 52 that is held by the casing 51 so that it can be opened and closed. Furthermore, before the base plate 2 is installed, the casing 51 is attached to the rear portion 60b of the toilet 60 via the fixing plate 53 and the screw bodies 70, 70 shown in Figure 1. Therefore, the fixing plate 53 and the screw bodies 70, 70 are also existing parts and are not included in the present invention. The rear portion 60b is provided with pre-formed fixing holes 60a, 60a through which the threaded bodies 70, 70 are inserted. The distance between the axial centers of the fixing holes 60a, 60a is d 60 The width direction W of the base plate 2 is such that it is parallel to the straight line L connecting the axial centers of the fixing holes 60a, 60a. 60 It is designed to be parallel to

[0027] Furthermore, the configuration of the base plate will be described with reference to Figures 2 and 3. Figure 2 is a plan view of the base plate. Figure 3 is a bottom view of the base plate. Note that the components shown in Figure 1 are given the same reference numerals in Figures 2 and 3, and their description will be omitted. As shown in FIG. 2, the base plate 2 is a flat plate having a substantially rectangular shape surrounded by long sides 2a and 2b and short sides 2c and 2d that are perpendicular to the long sides 2a and 2b. The long sides 2a and 2b are in the width direction W of the base plate 2, which coincides with the width direction of the cleaning toilet seat device 50. In addition, a notch 2n is formed near the center of the long side 2a to avoid interference with the nozzle cover 51c (see FIG. 7) provided on the casing 51. The short sides 2c and 2d are in the depth direction D of the base plate 2, which coincides with the front-to-back direction of the toilet seat cleaning device 50. The thickness direction H of the base plate 2 is perpendicular to both the width direction W and the depth direction D, and coincides with the up-down direction of the toilet seat cleaning device 50.

[0028] Furthermore, the base plate 2 has a first locking portion 6, a second locking portion 7 (see FIG. 3), an insertion hole 8, a washer insertion hole 9, and a recess 10 formed therein. The first locking portion 6 is a groove portion formed on the upper surface 2e of the base plate 2. Two first locking portions 6 are provided along the depth direction D of the base plate 2. This is because the fixing plate 53 is provided with a pair of holding holes 54, 54 (see FIG. 5).

[0029] The insertion holes 8 are holes that penetrate the base plate 2 in the thickness direction H. Two insertion holes 8 are formed along the width direction W of the base plate 2. The distance d7 between the axial centers of the insertion holes 8, 8 is 1 / 2 times the distance d between the axial centers of the fixing holes 60a, 60a. 60 (See FIG. 1). Furthermore, the straight line L7 connecting the axial centers of the insertion holes 8, 8 is equal to the straight line L 60 (See Figure 1)

[0030] The washer insertion hole 9 is a space required for installing a washer 71 (see FIG. 1) to prevent loosening of the screw body 70, and has opening ends 9a that open to the short sides 2c and 2d of the base plate 2. The width of the washer insertion hole 9 along the depth direction D and the height along the thickness direction H are equal to the diameter and thickness of the washer 71, respectively. The opposite end of the open end 9a is a closed end 9b, so that when the washer 71 reaches the closed end 9b, the screw body 70 (see FIG. 1) is inserted into the center hole of the washer 71.

[0031] The recess 10 is provided to prevent the upper surface 2e of the base plate 2 from interfering with the linear protrusion 51b (see FIG. 7) formed on the bottom surface 51a of the casing 51. Therefore, if the protrusion 51b is not formed on the bottom surface 51a, the recess 10 is omitted.

[0032] As shown in Fig. 3, the second locking portions 7 are grooves formed on the lower surface 2f of the base plate 2. Three second locking portions 7 are provided along the depth direction D of the base plate 2. The number of second locking portions 7 may be other than three, but increasing the number allows the support members 4 and 5 to support the base plate 2 more strongly.

[0033] Next, the configuration of the first mounting member and the support member will be described with reference to Fig. 4. Fig. 4 is a front view of the base plate, the first mounting member, the first locking portion, and the fixing member attached to the fixing plate. Note that the components shown in Figs. 1 to 3 are given the same reference numerals in Fig. 4, and their description will be omitted. As shown in Fig. 4, the first mounting member 3 has a cross section in the width direction W of the base plate 2, on a plane along the thickness direction H of the base plate 2 (hereinafter referred to as the WH plane), which is surrounded by an upper end 3a, a lower end 3b, and sides included in side ends 3c and 3d. The upper end 3a is a flat surface, and the lower end 3b has a locking protrusion T3 in the center that is shaped like an inverted T, with the top and bottom reversed. The cross section of the first locking portion 6 on the WH plane also has an inverted T shape.

[0034] The side ends 3c and 3d are connected to the upper end 3a by an upper step D 31 and the lower part D connected to the lower end 3b 32 It forms a staircase shape consisting of. Therefore, the first mounting member 3 has an upper portion D including an upper end 3a. 31 The upper portion D is engaged with the retaining hole 54 of the fixing plate 53, and the engagement projection T3 of the lower end 3b is engaged with the first engagement portion 6. 31 And the lower section D 32 The thickness of each of these is arbitrarily designed.

[0035] As mentioned above, the support members 4 and 5 are members for lifting and supporting the base plate 2 from the toilet bowl 60. Specifically, as shown in Figure 9, the nozzle cover 51c protrudes downward from the bottom surface 51a of the casing 51, so depending on the positioning of the base plate 2 in the front-to-rear direction of the cleaning toilet seat device 50, there is a risk of interference between the nozzle cover 51c and the toilet bowl 60. Therefore, the support members 4 and 5 are provided to avoid this interference. Another reason is that the installation of the base plate 2 raises the casing 51 higher than before, which may cause all or part of the back surface 52c of the toilet seat 52 to float above the upper end surface 60c of the toilet bowl 60. Such floating can cause excessive bending and rattle of the toilet seat 52 during use. Therefore, the inclination of the back surface 52c in the front-to-rear direction of the toilet seat 52 is adjusted to eliminate the floating.

[0036] The support member 4 has a vertical cross section on the WH plane that is bounded by the upper end 4a, the lower end 4b, and the sides included in the side ends 4c and 4d. The upper end 4a has a T-shaped locking protrusion T4 in its center, and the lower end 4b is a flat surface. The second locking portion 7 also has a T-shaped vertical cross section on the WH plane. Therefore, the locking protrusion T4 on the upper end 4a of the support member 4 is locked by the second locking portion 7. The side edges 4c and 4d are parallel to each other and have the same thickness, which can be arbitrarily designed. The thickness of side ends 5c, 5d (see FIG. 6) of support member 5 is also thicker than the thickness of side ends 4c, 4d of support member 4, and a T-shaped locking protrusion T5 on bottom end 5b is locked to second locking portion 7. Other than this, the configuration and function of support member 5 are the same as those of support member 4, so illustration of support member 5 is omitted.

[0037] Furthermore, the configuration of the fixing plate and the procedure for attaching the base plate to the fixing plate will be described with reference to Figures 5 and 6. Figure 5 is a view seen from the direction of arrow A in Figure 4. Figure 6 is a view seen from the direction of arrow B in Figure 4. Note that the components shown in Figures 1 to 4 are given the same reference numerals in Figures 5 and 6, and their description will be omitted. 5, the fixed plate 53 is a plate-like member fixed to the bottom surface 51a of the casing 51 (see FIG. 7), and has long sides 53a and 53b and short sides 53c and 53d. The width direction W of the base plate 2 is assumed to be parallel to the long sides 53a and 53b, and the depth direction D is assumed to be parallel to the short sides 53c and 53d. The long side 53a has a notch 53n near the center.

[0038] Furthermore, the fixing plate 53 has a pair of retaining holes 54, 54. The retaining holes 54, 54 are structured to receive and hold a pair of screw bodies 70, 70 that are inserted into fixing holes 60a, 60a of the toilet 60, respectively (see FIG. 1). Specifically, the retaining hole 54 has an elongated shape along the depth direction of the fixing plate 53 (i.e., the depth direction D of the base plate 2) so that the casing 51 can be fixed movably in the front-rear direction of the toilet bowl 60 (i.e., the depth direction D of the base plate 2). Furthermore, the retaining hole 54 has an opening width D on the upper surface 53e of the fixing plate 53. U The opening width D at the bottom 53f L To narrow the gap, step surfaces 54a, 54a are provided in the thickness direction of the fixing plate 53 (that is, the thickness direction H of the base plate 2). These step surfaces 54a, 54a are formed in a sawtooth shape.

[0039] Next, the procedure for attaching the base plate 2 to the fixing plate 53 is as follows: first, the screw bodies 70 are inserted into the insertion holes 8. Then, two first mounting members 3 are fitted into the retaining holes 54. At this time, since the side ends 3c and 3d are stepped, the upper end 3a is engaged with the stepped surfaces 54a of the retaining holes 54. Furthermore, as shown in FIG. 4, the lower end 3b protrudes downward from the lower surface 53f. Therefore, by simultaneously sliding the two lower ends 3b for each holding hole 54 into the first locking portions 6 of the base plate 2, the two lower ends 3b are locked to the first locking portions 6. In this way, the base plate 2 is attached to the lower surface 53f of the fixing plate 53.

[0040] 6, on the lower surface 2f of the base plate 2, the support members 4 and 5 are locked to the second locking portions 7. Furthermore, the side ends 4c and 4d of the support member 4 and the side ends 5c and 5d of the support member 5 are both trapezoidal. Specifically, when the support member 4 is aligned with the long side 2a and the notch 2n of the base plate 2 and the support member 5 is aligned with the long side 2b of the base plate 2 and engaged with the second engaging portion 7, the entire surface of the lower end 4b of the support member 4 and the entire surface of the lower end 5b of the support member 5 come into contact with the rear portion 60b (see FIG. 1) of the toilet bowl 60. In other words, the lower ends 4b and 5b are inclined relative to the upper end 4a and the lower end 5b, respectively, so that they are included in the same plane.

[0041] Furthermore, the state in which the toilet seat attachment 1 is attached to the toilet seat cleaning device 50 will be described with reference to Fig. 7. Fig. 7 is a bottom view of the toilet seat attachment according to the embodiment attached to the casing of the toilet seat device. Note that the same reference numerals are used in Fig. 7 for the components shown in Figs. 1 to 6, and their description will be omitted. As shown in Fig. 7, the fixing plate 53 to which the base plate 2 is attached is fixed to the bottom surface 51a of the casing 51 of the toilet seat cleaning device 50. Although not shown, a recessed area for accommodating the fixing plate 53 is provided in advance on the bottom surface 51a, so that the bottom surface 51a other than this recessed area and the lower surface 53f of the fixing plate 53 are substantially flush with each other. In addition, a linear protrusion 51b is provided on the bottom surface 51a, and this protrusion 51b fits into the recess 10 (see Fig. 5) on the upper surface 2e of the base plate 2, so that the base plate 2 is parallel to the bottom surface 51a.

[0042] Next, on the underside 52c of the toilet seat 52, cushions 52d, 52d are already provided near the tip 52a of the toilet seat 52, and cushions 52e, 52e are already provided near the base 52b of the toilet seat 52. Cushions 52d to 52e all have an oval three-dimensional shape, and cushion 52e is taller than cushion 52d.

[0043] Next, the state in which the cleaning toilet seat device is attached to the toilet bowl via a toilet seat attachment will be explained using Figures 8 and 9. Figure 8 is a front view of the cleaning toilet seat device when attached to the toilet bowl via a toilet seat attachment according to the embodiment. Figure 9 is a view seen from the direction of arrow C in Figure 8. Note that the components shown in Figures 1 to 7 are given the same reference numerals in Figures 8 and 9, and their explanation will be omitted. Also, Figure 8 shows the toilet seat in a raised state so that it cannot be sat on, and Figure 9 shows the toilet seat in a reclined state so that it can be sat on. 8 and 9, the cleaning toilet seat device 50 is fixed to the toilet bowl 60 using screw bodies 70, 70 and nuts 72, 72 (see FIG. 9) via the fixing plate 53 and the toilet seat attachment 1. The fixing plate 53 and the first mounting member 3 are housed in the bottom surface 51a of the casing 51 and cannot be seen, but the base plate 2 and the support members 4, 5 can be seen from the outside. Furthermore, the nozzle cover 51c protruding downward from the casing 51 is positioned in the space in front of the notch 2n due to the provision of the notch 2n of the base plate 2 and the support members 4 and 5. Therefore, there is no interference between the nozzle cover 51c and the toilet bowl 60.

[0044] 9, when the toilet seat 52 is in a seatable state, the height of the cushion 52d is lower than the height of the cushion 52e. Therefore, when the lower surface 2f of the base plate 2 is parallel to the horizontal upper end surface 60c of the toilet bowl 60, only the cushion 52d rises above the upper end surface 60c. However, because the thickness of the side end 5d of the support member 5 is thicker than the thickness of the side end 4d of the support member 4, the base plate 2 is tilted so that the long side 2a of the base plate 2 is closer to the upper end surface 60c than the long side 2b. Therefore, the cushion 52d comes into contact with the upper end surface 60c. Furthermore, since the side end 4d is trapezoidal with the front end 4A and rear end 4B of the support member 4 as the upper and lower bases, respectively, the entire surface of the lower end 4b abuts against the upper end surface 60c. In other words, the lower end 4b corresponds to the longer leg of the trapezoid. The same is true for the support member 5, where the entire surface of the lower end 5b abuts against the upper end surface 60c.

[0045] As described above, according to the toilet seat attachment 1, the distance d7 between the axial centers of the insertion holes 8, 8 of the base plate 2 is equal to the distance d 60 (see FIG. 1), the threaded bodies 70, 70 can be inserted into the fixing holes 60a, 60a without any difficulty. Therefore, the toilet seat attachment 1 can be securely attached to the existing toilet 60. Furthermore, the straight line L7 connecting the axial centers of the insertion holes 8, 8 is the same as the straight line L7 connecting the axial centers of the fixing holes 60a, 60a. 60 Since the toilet seat attachment 1 is parallel to the toilet bowl 60, the base plate 2 and the cleaning toilet seat device 50 are not arranged in a twisted position relative to the toilet bowl 60, resulting in a good appearance.

[0046] The first mounting member 3 has an upper portion D including an upper end 3a. 31 is engaged with the stepped surfaces 54a, 54a of the retaining hole 54 of the fixing plate 53, and the locking protrusion T3 on the lower end 3b is engaged with the first locking portion 6 of the base plate 2, so that the base plate 2 can be stably locked to the fixing plate 53. Furthermore, in the support members 4 and 5, the locking projections T4 and T5 are locked to the second locking portions 7, respectively, so that the support members 4 and 5 do not separate from the base plate 2 and can firmly support the base plate 2.

[0047] In addition, according to the toilet seat attachment 1, the first locking portion 6 is a groove portion provided along the depth direction D of the base plate 2, so that the relative position of the base plate 2 with respect to the fixed plate 53 can be finely adjusted along the front-to-back direction of the toilet 60. Because the second locking portion 7 is also a groove provided along the depth direction D of the base plate 2, the support members 4 and 5 can be slid along the second locking portion 7. This allows for fine adjustment of the inclination relative to the upper end surface 60c of the base plate 2. As a result, safety and comfort during use can be ensured, and deformation and damage to the toilet seat can be prevented. Furthermore, when the washer 71 reaches the closed end 9b, the screw body 70 is inserted into the center hole of the washer 71, so that positioning the washer 71 does not require much effort.

[0048] Therefore, the toilet seat attachment 1 is highly versatile, as it allows the cleaning toilet seat device 50 to be attached to various types of toilets 60 in a position that does not impede its cleaning function. Also, since it is possible to attach the cleaning toilet seat device 50 that the customer desires, it is expected that high customer satisfaction will be achieved. Furthermore, since no modification of the cleaning toilet seat device 50 is required for installation, there is no cost or effort required for modification, and installation is efficient. In addition, the toilet seat attachment 1 can be manufactured using, for example, a 3D printer, and therefore can be manufactured and its design modified relatively easily.

[0049] Next, a toilet seat attachment according to a first modified example of the embodiment will be described with reference to Fig. 10. Fig. 10 is a right side view of a cleansing toilet seat device attached to a toilet bowl via a toilet seat attachment according to a first modified example of the embodiment. Note that the same reference numerals are used in Fig. 10 for the components shown in Figs. 1 to 9, and their description will be omitted. As shown in Figure 10, the toilet seat attachment 1A according to the first modified example of the embodiment does not have the support members 4, 5 that are provided in the toilet seat attachment 1. Therefore, the second locking portion 7 may be omitted, but it is not necessary. Other than this, the configuration of the toilet seat attachment 1A is the same as the configuration of the toilet seat attachment 1 according to the embodiment.

[0050] Furthermore, the toilet seat attachment 1A can be attached to, for example, an existing toilet seat cleaning device 50A. The only difference between this toilet seat cleaning device 50A and the toilet seat cleaning device 50 is that the height of the cushion 52d and the cushion 52e provided on the back surface 52c of the toilet seat 52 are the same. Therefore, even if the toilet seat attachment 1A does not have the support members 4, 5, the cushion 52d will not rise above the upper end surface 60c. Furthermore, the nozzle cover 51c does not interfere with the upper end surface 60c at the rear portion 60b, due to differences in the size of the toilet 60A in the front-rear direction and the mounting position of the base plate 2 relative to the depth direction of the fixing plate 53.

[0051] Therefore, the toilet seat attachment 1A can be attached to the toilet bowl 60A in a simpler procedure because it does not require the support members 4 and 5. Other than this, the functions and effects of the toilet seat attachment 1A are the same as those of the toilet seat attachment 1 according to the embodiment.

[0052] Furthermore, a toilet seat attachment according to a second modified embodiment will be described with reference to Figures 11 to 13. Figure 11 is an exploded perspective view of the toilet seat attachment according to the second modified embodiment. Figure 12 is a perspective view of a support member constituting the toilet seat attachment according to the second modified embodiment when attached to a toilet seat. Figure 13 is a right side view of a support member constituting the toilet seat attachment according to the second modified embodiment when attached to a toilet bowl. Note that the components shown in Figures 1 to 10 are given the same reference numerals in Figures 11 to 13, and their description will be omitted. As shown in Figure 11, the toilet seat attachment 1B according to the second modified example of the embodiment has a base plate 2' instead of the base plate 2 provided in the toilet seat attachment 1A, and has a second mounting member 11 instead of the first mounting member 3. In the base plate 2', the insertion holes 8, 8 and the washer insertion holes 9, 9 are arranged closer to the long side 2b than in the base plate 2. Other than this, the configuration of the base plate 2' is the same as that of the base plate 2.

[0053] The second mounting member 11 has an upper portion D including a flat upper end 11a. 11 And this upper part D 11 Lower part D overlaps from below 12 Upper part D 11 The lower portion D is a rectangular plate-shaped member, and sawtooth portions 11b, 11b are formed on both ends of the rear surface thereof. 12The width of the upper part D 11 Narrower than. Further, the second mounting member 11 has a mounting insertion hole 12 formed therethrough for inserting the existing screw body 70A therethrough. The second mounting members 11, 11 are locked to a fixing plate 55 having holding holes 56, 56.

[0054] The holding hole 56 is wider in the width direction W and shorter in the depth direction D than the holding hole 54 of the fixing plate 53. Similarly to the holding hole 54, the holding hole 56 is formed with sawtooth stepped surfaces 56a, 56a. Therefore, the sawtooth portions 11b, 11b of the second mounting member 11 engage with the step surfaces 56a, 56a, and the upper step portion D including the upper end 11a of the second mounting member 11 11 is locked in the retaining hole 56.

[0055] Furthermore, the toilet seat attachment 1B is equipped with a lift member 13, as shown in Figure 12. This lift member 13 is attached to the cushion 52h closest to the base end 52b of the cushions 52g and 52h already provided on the back surface 52c of the toilet seat 52 of the toilet seat cleaning device 50B. The cushions 52g and 52h have the same shape. The lift member 13 is a box-shaped body having an inner space 13a that has the same shape as the cushion 52h. The outer bottom surface 13b of the lift member 13 has a flat oval shape.

[0056] As shown in Figure 13, the toilet 60A to which the toilet seat attachment 1B is attached has an upper end surface 60c' that slopes slightly upward as it approaches the front portion 60d of the toilet 60A. Therefore, if the lifting member 13 is not provided, the cushion 52h will rise above the upper end surface 60c'. Therefore, when the lifting member 13 is attached by placing it over the cushion 52h, the outer bottom surface 13b abuts against the upper end surface 60c'. Therefore, the lifting member 13 supports the toilet seat 52 together with the cushions 52g and 52h.

[0057] According to the toilet seat attachment 1B, the lift member 13 supports the toilet seat 52, preventing damage to the toilet seat 52 due to bending. This not only extends the product life of the toilet seat 52, but also prevents unexpected shaking when a user sits on the toilet seat 52. This prevents disadvantages such as reduced comfort during use. Other functions and effects of the toilet seat attachment 1B are the same as those of the toilet seat attachment 1A.

[0058] The toilet seat attachment according to the present invention is not limited to the one shown in the embodiment. For example, the first locking portion 6 of the base plate 2 may be a plurality of dots arranged in a straight line at intervals. Also, one of the support members 4, 5 may be omitted, and the remaining other may be positioned closer to the center of the short sides 2c, 2d. Furthermore, the lift member 13 may be provided on the toilet seat attachment 1, 1A. [Industrial Applicability]

[0059] The present invention can be used as a toilet seat attachment for attaching a toilet seat device to a toilet bowl. [Explanation of symbols]
