Disclosure of Invention

Problems to be solved by the invention

However, in the conventional configuration, the housing recess provided in the back side plate portion has an internal structure capable of fixing the seated switch without displacement, and the opening area thereof is substantially the same size as the cross-sectional area of the seated switch and is relatively small, so that it is difficult to perform the work.

More specifically, since the opening of the accommodation recess is small, it is not an easy task to take out the conductive wire accommodated in the interior of the toilet seat main body from the opening or to accommodate the seating switch in a state of being connected by wiring into the accommodation recess. Further, the displacement plate for appropriately operating the seat switch needs to be attached so as to cover the seat switch, but this operation must be performed in a state where the seat switch is accommodated in the accommodation recess, and therefore the workability of this attachment operation is also poor.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a toilet seat device capable of improving workability of attaching a seat switch to a toilet seat main body.

Means for solving the problems

In order to achieve the above object, a toilet seat device according to the present invention includes a toilet seat body rotatably attached to a toilet, and a seat switch attached to a back plate portion of the toilet body and connected to a conductive wire housed and arranged inside the toilet seat body, and includes a switch housing member for housing and holding the seat switch; an accommodation recess is formed in the back side plate portion of the toilet seat main body so as to communicate with the interior of the toilet seat main body, and the accommodation recess accommodates the switch accommodation member accommodating and holding the seat switch from the back side of the toilet seat main body.

Effects of the invention

The toilet seat device of the present invention is configured as described above, and therefore, the installation workability of the seat switch to the toilet seat main body can be improved.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, a basic structure of the toilet seat device 1 will be described.

The toilet seat device 1 includes a toilet seat body 10 rotatably attached to a toilet (not shown), a seat switch 50, and a switch housing member 30 housing and holding the seat switch 50. The seat switch 50 is connected to the conductive wire 12 housed and arranged in the interior 11 of the toilet seat body 10, and is attached to the back plate portion 13 of the toilet seat body 10. A housing recess 20 is formed in the rear plate portion 13 of the toilet seat main body 10 so as to communicate with the interior 11 of the toilet seat main body 10, and a switch housing member 30 housing and holding a seated switch 50 is attached from the back side of the toilet seat main body 10 and housed in the housing recess 20.

Next, the details of the toilet seat device 1 will be described. Hereinafter, the vertical direction will be described with reference to the state where the back side of the toilet seat main body 10 faces upward.

As shown in the plan view of the rear surface side of the toilet seat body 10 in fig. 1 (a), the toilet seat device 1 of the present embodiment includes switch units S each having a seating switch 50 mounted therein at two positions on the front side of the rear surface of the toilet seat body 10. These switch sections S have substantially the same internal structure, and a seating switch 50 is incorporated in an accommodation recess 20 provided in the back plate section 13, and a pressing operation member 70 is attached so as to close an opening of the accommodation recess 20. As described above, the seated switch 50 is accommodated in the accommodation recess 20 in a state of being accommodated in the switch accommodation member 30.

Fig. 1 (b) is a partially enlarged perspective view of the portion a of fig. 1 (a) with the pressing member 70 removed. Fig. 2 is a partially enlarged schematic cross-sectional view showing a state in which the pressing operation member 70 is attached to the accommodation recess 20 of the back plate portion 13 corresponding to a position of line B-B in fig. 1 (a).

As shown in fig. 1 (b) and 2, the receiving recess 20 is a receiving space formed by projecting downward an inner edge 21 of the opening of the back plate portion 13 and having a substantially elliptic cylindrical shape in plan view, and as shown in fig. 2, the lower portion and a part of the side portion are opened and communicate with the interior 11 of the toilet seat main body 10. The inner edge 21 of the opening has a stepped portion 22 on the lower side and a holding portion 23 having a shape narrower than the upper portion on the lower side. Further, at an opening edge on the upper surface side of the housing recess 20, a pressing operation member placement portion 24 is formed one step lower than the peripheral portion of the opening.

As shown in fig. 1 (a), 3, and 4, the switch housing member 30 has an oblong shape substantially conforming to the planar shape of the housing recess 20. A plurality of flange pieces 40 are formed at the center in the vertical direction of the outer surface of the switch housing member 30 along the circumferential direction. The switch housing member 30 is housed in the housing recess 20 in a state where the flange piece 40 is placed on the upper surface of the step portion 22 and the lower portion (the leg portion 41) is sandwiched by the sandwiching portion 23. In a state where the switch housing member 30 is housed in the housing recess 20, a gap space 26 is formed over substantially the entire circumference between the switch housing member 30 and the opening inner edge portion 21 of the housing recess 20.

In this way, since the housing recess 20 houses the seat switch 50 in a state of being covered with the switch housing member 30, the opening area thereof is sufficiently larger than the planar size of the seat switch 50 (see fig. 1 (b)).

On the other hand, the pressing operation member 70 is formed of an elastic material such as rubber, and includes an oblong operation portion 71, a leg portion 73 extending downward in a peripheral wall shape over substantially the entire circumference below the operation portion 71, and a flange portion 74 extending outward of the operation portion 71.

The operation portion 71 is elastically deformable so as to be pressed downward, and as shown in fig. 2, a central portion thereof protrudes upward, while a pressing portion 72 protruding downward in a rod shape is provided at a central portion of a lower surface of the central portion in order to operate the seat switch 50.

The leg portion 73 is a hanging wall fitted into a gap space 26 formed between an inner surface of the opening inner edge portion 21 of the accommodation recess 20 and an outer surface of the switch accommodation member 30. The flange portion 74 is a projection piece that is placed on the pressing operation member placement portion 24 of the accommodation recess 20.

As shown in fig. 1 (b) and 2, the switch housing member 30 is housed in the housing recess 20 such that the flange piece 40 of the switch housing member 30 is placed on the step portion 22 of the inner edge portion 21 of the opening, and the leg portion 73 of the pressing operation member 70 is fitted into the gap space 26 and attached thereto. By attaching the pressing operation member 70, the flange piece 40 of the switch housing member 30 is sandwiched between the leg portion 73 and the step portion 22, and the switch housing member 30, the pressing operation member 70, and the housing recess 20 (the back side plate portion 13) are firmly fixed.

When the operation portion 71 of the pressing operation member 70 is pressed from above, the pressing portion 72 that moves downward due to the deformation of the operation portion 71 pushes down the displacement plate 60, and the detection portion 52 provided in the switch main body 51 of the seat switch 50 is operated. In the toilet seat in the use state of the toilet, the back plate portion 13 of the toilet seat body 10 is directed downward, the upper surface of the operation portion 71 of the pressing operation member 70 is brought into contact with the upper surface (not shown) of the gasket (rim) of the toilet seat body (not shown), and the pressing portion 72 is pushed up by the sitting of the user. That is, the displacement plate 60 is pushed up by the pressing force from the upper surface of the washer, and the seating switch 50 operates.

The seat switch 50 includes a switch main body 51 and a displacement plate 60, and the switch main body 51 includes a detection unit 52 that detects displacement according to a load. The displacement plate 60 is a spring plate, covers the switch body 51 housed in the housing space 31 of the switch housing member 30, and is fitted close to the detection portion 52 to close the opening of the housing space 31.

The switch body 51 has a wiring connection portion 53 at a lower portion thereof, and in a state of being accommodated in the switch accommodating member 30, can be connected to the conductive wire 12 accommodated and arranged in the interior 11 of the toilet seat body 10 through the lower opening 25 of the switch accommodating member 30. As shown in fig. 2, the lower opening 25 may be an opening through which the conductive wire 12 can be connected from either the lateral side or the lower side.

Next, the switch housing member 30 and the seat switch 50 will be described with reference to fig. 3 to 7.

The switch housing member 30 has an oblong shape in plan view, has a housing space 31 for housing the switch body 51 of the seated switch 50, and has a peripheral wall portion 33 formed so as to surround the housing space 31. The peripheral wall portion 33 is sectioned by a slit 32 (a vertical opening that is open at both the top and bottom) extending in the standing direction thereof. The slit 32 is formed at one end side in the longitudinal direction of the switch housing member 30. In short, the slit 32 allows both side portions of the cut peripheral wall portion 33 to be deformed outwardly by flexing about the other end side in the longitudinal direction as a fulcrum, so that the slit 32 is expanded.

The peripheral wall portion 33 is a hollow double-walled portion, and a bottomed housing space 31 having a substantially rectangular shape in plan view defined by an inner edge of the peripheral wall portion 33 and having an outer shape is formed inside the peripheral wall portion 33. As shown in fig. 3 and 4, the housing space 31 includes a short direction fixing portion 37, a long direction fixing portion 38, and a claw portion 39 for pressing the switch body 51 from above, the short direction fixing portion 37 and the long direction fixing portion 38 facing each other for positioning and fixing the switch body 51 (shown by a two-dot chain line in fig. 4).

Further, on the inner side (upper portion of the inner wall surface) of the peripheral wall portion 33 of the switch housing member 30, a protrusion portion 34 is disposed that engages the long side edge portions 63a (peripheral edge portions 63) of the two opposing sides of the displacement plate 60. Further, at a position (short side) of the peripheral wall portion 33 facing the slit 32, a locking portion 35 for locking a short side edge portion 63b (peripheral edge portion 63) of the displacement plate 60 is disposed. As shown in fig. 5, guide surfaces 34a and 35a inclined downward toward the housing space 31 are formed on the upper surfaces of the projection 34 and the locking portion 35.

Further, a convex portion 36 protruding toward the housing space 31 is formed below each of the protrusion 34 and the locking portion 35 provided on the peripheral wall portion 33. The protrusion 34 and the locking portion 35 respectively hold and lock the displacement plate 60 by fitting the peripheral edge 63 of the displacement plate 60 into the gap with the convex portion 36.

The bottom plate portion 42 provided below the housing space 31 has a part of its opening on the slit 32 side (one end side in the longitudinal direction), an opening 43 communicating with the slit 32, and a continuous opening 44 communicating with the interior 11 of the toilet seat body 10 through the lower opening 25 (see fig. 2) of the housing recess 20. A concave opening 42a is formed at an edge of the bottom plate portion 42 on the slit 32 side, and a part of the lower portion of the switch main body 51 is disposed to protrude downward from the opening 43 and the concave opening 42 a.

The flange piece 40 is provided separately at 4 on the outer surface of the peripheral wall 33. A leg portion 41 (see fig. 4 and 5) corresponding to the cut peripheral wall portion 33 is formed below the flange piece 40. Therefore, the leg portion 41 is integrated with the peripheral wall portion 33 and is deformed by bending.

As described above, in a state where the switch housing member 30 is accurately housed in the housing recess 20, the leg portion 41 is sandwiched between the sandwiching portions 23 (see fig. 4) from both outer sides. That is, when the switch housing member 30 is in the housed state, the peripheral wall portion 33 and the leg portion 41 are restricted from being deformed outward by the clip portion 23.

Next, the procedure of attaching the seated switch 50 (the switch main body 51 and the displacement plate 60) to the switch housing member 30 will be described with reference to fig. 5 to 7.

First, the conductive wire 12 is temporarily provided to the back side plate portion 13. At this time, one end of the conductive wire 12 is drawn out from the hinge portion of the toilet seat device 1, and the other end is temporarily disposed in the vicinity of the accommodation recess 20.

In this state, the back plate 13 is welded to the front plate.

Next, the conductive wires 12 accommodated therein are drawn out from the accommodation recess 20 provided in the back-side plate portion 13.

Then, the conductive wire 12 drawn out from the interior 11 of the toilet seat body 10 is connected to the wiring connection portion 53 (see fig. 2) of the switch body 51 by welding or the like, and then the switch body 51 is accommodated in the accommodation space 31 (see fig. 5) of the switch accommodation member 30.

Since the opening area of the housing recess 20 is sufficiently larger than the cross-sectional area of the switch body 51, the lead wire 12 can be easily drawn out from the interior 11 of the toilet seat body 10 and the switch body 51 connected to the lead wire 12 can be easily housed in the interior 11. In the present embodiment, since the slit 32 communicates with the opening 43 on the bottom side to form the large continuous opening 44, the operation of accommodating the switch main body 51 connected to the conductive wire 12 into the accommodating space 31 is particularly easy.

Next, the procedure for attaching the displacement plate 60 will be described. The displacement plate 60 includes an operation spring plate 61 (see fig. 6) that is elastically displaced downward and comes into contact with the detection portion 52 of the switch main body 51, and a support spring plate 62 (see fig. 7) that overlaps the upper surface of the operation spring plate 61. Which spring plate is made of a thin plate material having a substantially rectangular shape whose outer shape coincides with the planar shape of the opening of the housing space 31.

The operating spring plate 61 has a rectangular operating piece 61a formed in the center thereof, which has a small short side and a long side, and is easily bent, with only 1 short side connected to the periphery, and a holding piece 61b formed in the periphery thereof, which holds the operating piece 61a through a gap such as a notch. Further, the supporting spring plate 62 is not processed by a gap or the like.

As shown in fig. 6 and 7, the displacement plates 60 may be attached one by one in the order of the operating spring plate 61 (see fig. 6) and the supporting spring plate 62 (see fig. 7). Of course, two sheets may be mounted in an overlapping manner.

The peripheral edge 63 (short edge 63b) on the fulcrum side of the operation spring plate 61 is inserted into the gap between the locking portion 35 provided on the inner wall surface of the peripheral wall 33 and the protruding portion 36, and is temporarily held in an inclined state by the operator, for the operation spring plate 61. Then, by pushing down the inclined upper portion of the operation spring plate 61, the peripheral edge portions 63 (both long-side edge portions 63a) pass below the protrusion 34 (on the side of the housing space 31), and the operation spring plate 61 is fitted between the protrusion 34 and the convex portion 36. Thus, the operation spring plate 61 is disposed and held at an appropriate position in the housing space 31.

Similarly, the support spring plate 62 has one peripheral edge portion 63 (short edge portion 63b) fitted into a gap between the locking portion 35 and the operation spring plate 61 in contact with the convex portion 36, and is temporarily held in an inclined state by the operator. Then, by pushing down the inclined upper portion of the support spring plate 62, the peripheral edge portion 63 (both long-side edge portions 63a) goes over the protrusion 34 and is fitted between the protrusion 34 and the operation spring plate 61. Thus, the supporting spring plate 62 is disposed and held in place in the housing space 31.

Since the peripheral wall portion 33 is cut by the slit 32, the displacement plates 60 can be easily attached. That is, when the displacement plate 60 is fitted, the peripheral edge 63 of the displacement plate 60 goes beyond the projection 34 toward the housing space 31, and accordingly, both side portions of the cut peripheral wall 33 are deflected outward so as to be separated from each other. The bending deformation and the action of the guide surface 34a of the projection 34 complement each other, and the peripheral edge 63 can easily get over the projection 34. In this way, the displacement plate 60 can be easily attached to the switch housing member 30, as in the case of the switch main body 51.

In the present embodiment, since the inner edge of the peripheral wall portion 33 has a substantially rectangular planar shape and the slit 32 is provided on one short side of the rectangle, both side portions of the peripheral wall portion 33 on the long side are easily deformed by bending, and the displacement plate 60 can be more easily attached.

Further, as in the present embodiment, it is preferable that the protrusion 34 is provided at a position near the slit 32 and the locking portion 35 is provided at a position facing the slit 32, in order to lock the displacement plate 60 in a balanced manner. By providing the projection 34 and the locking portion 35 in this manner, the displacement plate 60 can be easily attached by the turning operation with the locking portion 35 side as a fulcrum, as shown in fig. 5 and 6. The positions and the number of the projections 34 and the locking portions 35 are not limited to those in the present embodiment. The number of the projecting portions 34 and the locking portions 35 may be two or more, and 1 may be provided on each of the opposing sides.

In this way, in the switch housing member 30, the switch main body 51 and the displacement plate 60 connected to the conductive wire 12 are appropriately mounted in the housing space 31. The switch housing member 30 in this state can be housed in the housing recess 20 of the toilet seat body 10 with this state maintained.

As described above, in the present toilet seat device 1, the seating switch 50 (switch body 51) does not need to be directly accommodated in the accommodation recess 20, and can be accommodated in the accommodation recess 20 having a large opening corresponding to the switch accommodation member 30 in a state of being attached to the member. Therefore, workability is significantly improved as compared with the conventional one.

Further, since the continuous opening 44 including the slit 32 provided in the switch housing member 30 communicates with the lower opening 25 provided in the accommodation recess 20 and leading to the interior 11 of the toilet seat main body 10, the return of the connected conductive wire 12 to the interior 11 can be easily performed.

When the switch housing member 30 is accommodated in the accommodating recess 20, the leg portion 41 is sandwiched by the sandwiching portion 23 (see fig. 2) formed in the accommodating recess 20, the expansion of the slit 32 is restricted, and the outward flexural deformation of the peripheral wall portion 33 is restricted. Therefore, the displacement plate 60 is prevented from being detached by the outward expansion deformation of the peripheral wall portion 33 after the switch housing member 30 is mounted and housed in the housing recess 20.

In the present embodiment, the displacement plate 60 is easily attached by providing the slit 32 in the switch housing member 30, but the present invention is not limited to such a modified structure. In short, the displacement plate 60 may have another structure as long as it is deformed by being fitted into the accommodation recess 20 to be deflected outward, and the displacement plate 60 is held by pressure contact while being restricted from being deformed by being fitted into the accommodation recess 20. For example, the displacement plate 60 may be easily attached by using an elastic body such as rubber.
