BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the accompanying drawings. First, the basic configuration 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 bowl (not shown), a seat switch 50, and a switch housing member 30 in which the seat switch 50 is housed. The seat switch 50 is connected to the conductive wire 12 housed and wired in the interior 11 of the toilet seat body 10 and attached to the back plate portion 13 of the toilet seat body 10 . The back plate portion 13 of the toilet seat body 10 has a storage recess 20 in which a switch housing member 30 housing and holding a seat switch 50 is attached from the back side of the toilet seat body 10 so as to communicate with the interior 11 of the toilet seat body 10. formed.

Next, details of the toilet seat device 1 will be described. In the following description, the vertical direction is defined with reference to the state in which the toilet seat body 10 is turned upside down.

As shown in the plan view of the back side of the toilet seat body 10 of FIG. I have. All of these switch portions S have substantially the same internal structure. is installed. The seating switch 50 is housed in the housing recess 20 while being housed in the switch housing member 30 as described above.

FIG. 1(b) is a partially enlarged perspective view of the portion A in FIG. 1(a) with the pressing member 70 removed. FIG. 2 is a partially enlarged schematic cross-sectional view showing how the pressing operation member 70 is attached to the housing recess 20 of the back plate portion 13, corresponding to the position of line BB in FIG. 1(a).

As shown in FIGS. 1(b) and 2, the storage recess 20 is a storage space having a substantially elliptical cylinder shape in a plan view formed by projecting downward from an opening inner edge portion 21 of the back plate portion 13. As shown in FIG. 2, the lower portion and part of the side portions are opened to communicate with the interior 11 of the toilet seat body 10. As shown in FIG. The opening inner edge portion 21 has a stepped portion 22 on the lower side, and further has a holding portion 23 that is narrower than the upper portion thereof. At the edge of the opening of the storage recess 20 on the upper surface side, there is formed a placing portion 24 for pressing operation member which is stepped down from the peripheral portion of the opening.

As shown in FIGS. 1A, 3 and 4, the switch housing member 30 has an elongated elliptical shape that substantially matches the planar shape of the housing recess 20. As shown in FIG. A plurality of flange pieces 40 separated along the circumferential direction are formed in the center of the outer surface of the switch housing member 30 in the vertical direction. The switch housing member 30 is housed in the housing recess 20 with the flange piece 40 placed on the upper surface of the stepped portion 22 and the lower portion (foot portion 41 ) sandwiched between the holding portions 23 . Also, when the switch housing member 30 is housed in the housing recess 20 , a clearance space 26 is formed between the switch housing member 30 and the inner edge 21 of the opening of the housing recess 20 .

As described above, the seat switch 50 is stored in the storage recess 20 with the seat switch 50 covered with the switch storage member 30, so that the opening area of the storage recess 20 is sufficiently larger than the planar dimension of the seat switch 50. (See FIG. 1(b)).

On the other hand, the pressing operation member 70 is made of an elastic material such as rubber. and a flange portion 74 extending to the outside of the portion 71 .

The operation part 71 is elastically deformable so as to be pushed downward, and as shown in FIG. A pressing portion 72 protruding downward in a bar shape is provided for pressing the button.

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

As shown in FIGS. 1(b) and 2, the switch housing member 30 is housed in the housing recess 20 so that the flange piece 40 of the switch housing member 30 rests on the stepped portion 22 of the opening inner edge portion 21. The pressing operation member 70 is attached by fitting the leg portion 73 into the clearance space 26 . By attaching the pressing operation member 70 so that the flange piece 40 of the switch housing member 30 is sandwiched between the leg portion 73 and the stepped portion 22, the switch housing member 30, the pressing operation member 70, and the housing member 30 can be stored. A strong fixed relationship is formed with the recess 20 (back plate portion 13).

When the operating 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 operating portion 71 presses down the displacement plate 60, and the detection portion provided in the switch body 51 of the seating switch 50 is activated. 52 is activated. When the toilet is in use, the back plate 13 of the toilet seat main body 10 faces downward, and the upper surface of the operating portion 71 of the pressing operation member 70 is in contact with the rim upper surface (not shown) of the toilet main body (not shown). When the user sits on the seat, the pressing portion 72 pushes up. That is, the seating switch 50 is activated by pushing up the displacement plate 60 due to the pressing force from the upper surface of the rim.

The seating switch 50 includes a switch body 51 having a detection portion 52 for detecting displacement by load, and a displacement plate 60 . The displacement plate 60 is a spring plate fitted so as to cover the switch body 51 accommodated in the accommodation space 31 of the switch accommodation member 30 and to close the opening of the accommodation space 31 so as to be close to the detection portion 52 .

Also, the switch body 51 has a wiring connection portion 53 at its lower portion, and when housed in the switch housing member 30 , it is housed in the interior 11 of the toilet seat body 10 through the lower opening 25 of the switch housing member 30 . It is designed to be connectable with the wired conductive wire 12 . As shown in FIG. 2, the lower opening 25 may be an opening that allows the conductive line 12 to be connected either from the side or from the bottom.

Next, the switch housing member 30 and the seating switch 50 will be described with reference to FIGS. 3 to 7. FIG.

The switch housing member 30 has an elongated elliptical shape in plan view and has a housing space 31 for housing the switch body 51 of the seating switch 50 . The peripheral wall portion 33 is divided by slits 32 (longitudinal openings with both top and bottom openings) extending in the upright direction. The slit 32 is formed at one longitudinal end of the switch housing member 30 . In short, the slit 32 allows both side portions of the peripheral wall portion 33, which is divided so as to expand the slit 32, to bend and deform outward with the other end side in the longitudinal direction as a fulcrum.

The peripheral wall portion 33 is a hollowed double wall, and in the interior surrounded by the peripheral wall portion 33, there is a bottomed accommodation space 31 which is substantially rectangular in plan view and whose outer shape is determined by the inner edge of the peripheral wall portion 33. is formed. As shown in FIGS. 3 and 4, the accommodation space 31 includes lateral direction fixing portions 37 opposed to each other for positioning and fixing the switch body 51 (illustrated by the two-dot chain line in FIG. 4), and longitudinal direction fixing portions 37. It has a direction fixing portion 38 and a claw piece portion 39 that presses the switch body 51 from above.

In addition, inside the peripheral wall portion 33 of the switch housing member 30 (upper portion of the inner wall surface), a projecting portion 34 is arranged for locking the longitudinal edge portions 63a (peripheral edge portions 63) of the two opposite sides of the displacement plate 60. is set. Furthermore, at a position (on the short side) of the peripheral wall portion 33 facing the slit 32 , a locking portion 35 for locking the short side edge portion 63 b (peripheral edge portion 63 ) of the displacement plate 60 is provided. . As shown in FIG. 5 , guide surfaces 34 a and 35 a inclined downward toward the housing space 31 are formed on the upper surfaces of the protrusion 34 and the locking portion 35 .

Further, a convex portion 36 protruding toward the housing space 31 is formed below the projection portion 34 and the locking portion 35 provided on the peripheral wall portion 33 . Each of the projecting portion 34 and the locking portion 35 holds and locks the displacement plate 60 by fitting the peripheral edge portion 63 of the displacement plate 60 into the gap with the convex portion 36 .

A bottom plate portion 42 provided below the storage space 31 is partially opened on the side of the slit 32 (one end side in the longitudinal direction), and the opening 43 and the slit 32 communicate with each other. It communicates with the interior 11 of the toilet seat body 10 via the lower opening 25 of the recess 20 . A concave opening 42a is formed in the edge of the bottom plate portion 42 on the side of the slit 32, and a part of the lower portion of the switch body 51 is arranged to protrude downward from the opening 43 and the concave opening 42a.

Further, the above-described flange pieces 40 are separately provided at four locations on the outer surface of the peripheral wall portion 33 . A leg portion 41 (see FIGS. 4 and 5) corresponding to the divided peripheral wall portion 33 is formed below the flange piece 40 . Therefore, the leg portion 41 is flexurally deformed integrally with the peripheral wall portion 33 .

As described above, when the switch housing member 30 is properly housed in the housing recess 20, the leg portion 41 is sandwiched between the sandwiching portions 23 (see FIG. 4) from both outer sides. In other words, when the switch housing member 30 is in the housed state, the clamping portion 23 restricts the outward bending deformation of the peripheral wall portion 33 and the foot portion 41 .

Next, a procedure for mounting the seating switch 50 (switch body 51 and displacement plate 60) to the switch housing member 30 will be described with reference to FIGS. 5 to 7. FIG.

First, the conductive wire 12 is temporarily placed on the back plate portion 13 . At this time, one end of the conductive wire 12 is pulled out from the hinge portion of the toilet seat device 1 and the other end is temporarily placed in the vicinity of the storage recess 20 .
In this state, the back plate portion 13 and the front plate portion are welded.
Next, the conductive wire 12 stored inside is pulled out from the storage recess 20 provided in the back plate portion 13 .
Then, after connecting the conductive wire 12 pulled out from the interior 11 of the toilet seat body 10 to the wiring connection portion 53 of the switch body 51 by soldering or the like, the switch body 51 is housed in the housing space 31 of the switch housing member 30 ( See Figure 5).

Since the opening area of the storage recess 20 is sufficiently large compared to the cross-sectional area of the switch body 51, the lead-out of the conductive wire 12 from the interior 11 of the toilet seat body 10 and the interior of the switch body 51 to which the conductive wire 12 is connected 11 can be easily accommodated. In this embodiment, the slit 32 and the opening 43 on the bottom side communicate with each other to form a large continuous opening 44. Therefore, the work of accommodating the switch main body 51 to which the conductive wire 12 is connected into the accommodation space 31 is required. is particularly easy.

Next, a procedure for attaching the displacement plate 60 will be described. The displacement plate 60 includes an operating spring plate 61 (see FIG. 6) that contacts the detection portion 52 of the switch body 51 by being elastically displaced downward, and a supporting spring plate 62 (see FIG. 6) superimposed on the upper surface of the operating spring plate 61 ( See FIG. 7). Each spring plate is made of a substantially rectangular thin plate material that matches the shape of the opening of the accommodation space 31 in a plan view.

The operating spring plate 61 has an operating piece 61a formed by a notch in the center thereof, the width of which is reduced and the operating piece 61a elongated in the longitudinal direction for easy bending. ing. Further, the support spring plate 62 is not processed such as notching.

As shown in FIGS. 6 and 7, such a displacement plate 60 may be mounted one by one in the order of an operating spring plate 61 (see FIG. 6) and a support spring plate 62 (see FIG. 7). Of course, two sheets may be stacked and attached.

The operating spring plate 61 is inserted into the gap between the engaging portion 35 provided on the inner wall surface of the peripheral wall portion 33 and the convex portion 36 at the peripheral edge portion 63 (short side edge portion 63b) of the operating spring plate 61 on the fulcrum side, It is temporarily held in an inclined state by the operator. As the inclined upper portion of the operating spring plate 61 is pushed downward, the peripheral edge portion 63 (both longitudinal peripheral edge portions 63a) rides over the projecting portion 34 (on the accommodation space 31 side), and the operating spring plate 61 is It is fitted between the projecting portion 34 and the projecting portion 36 . In this way, the operating spring plate 61 is arranged and held at an appropriate position in the housing space 31 .

Similarly, the support spring plate 62 is also fitted with one peripheral edge portion 63 (short side edge portion 63b) in the gap between the locking portion 35 and the operating spring plate 61 in contact with the convex portion 36, and is temporarily held at an angle to the When the inclined upper portion of the support spring plate 62 is pushed downward, the peripheral edge portion 63 (both longitudinal edge portions 63 a ) climbs over the projection portion 34 and is fitted between the projection portion 34 and the operating spring plate 61 . Thus, the support spring plate 62 is arranged and held at an appropriate position in the housing space 31 .

Since the peripheral wall portion 33 is divided by the slits 32, these displacement plates 60 can be easily attached. That is, when the displacement plate 60 is fitted, the peripheral edge portion 63 of the displacement plate 60 climbs over the protrusion 34 toward the accommodation space 31, and along with this, both sides of the separated peripheral wall portion 33 are separated from each other. It flexes and deforms. The flexural deformation and the action of the guide surface 34a of the protrusion 34 combine to allow the peripheral portion 63 to easily climb over the protrusion 34. As shown in FIG. Thus, the displacement plate 60 can be easily attached to the switch housing member 30 in the same manner as the switch body 51 .

In addition, in the present embodiment, the inner edge of the peripheral wall portion 33 has a substantially rectangular shape in plan view, and the slits 32 are provided on one short side of the rectangle. It is easy to deform, and the mounting of the displacement plate 60 becomes easier.

In addition, as in the present embodiment, 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, which locks the displacement plate 60 in a well-balanced manner. desirable to do so. In addition, by arranging the projecting portion 34 and the engaging portion 35 in this way, as shown in FIGS. can be done. The position and number of projections 34 and locking portions 35 are not limited to those of the present embodiment. The total number of projections 34 and locking portions 35 may be two or more, and one may be provided on each opposite side.

In this way, the switch main body 51 to which the conductive wire 12 is connected and the displacement plate 60 are properly attached to the housing space 31 of the switch housing member 30 . The switch housing member 30 in this state can be stored in the housing recess 20 of the toilet seat body 10 as it is.

As described above, in the present toilet seat device 1, there is no need to store the seat switch 50 (switch body 51) directly in the storage recess 20, and in the state of being attached to the switch housing member 30, a large opening matching the member can be stored. It can be stored in the recess 20 . Therefore, the workability is remarkably improved as compared with the conventional one.

Further, since the continuous opening 44 including the slit 32 provided in the switch housing member 30 and the lower opening 25 leading to the interior 11 of the toilet seat body 10 provided in the housing recess 20 communicate with each other, the connected conductive wire 12 can be easily returned inside.

Further, when the switch housing member 30 is housed in the housing recess 20 , the foot portion 41 is sandwiched between the clamping portions 23 formed in the housing recess 20 , restricting the expansion of the slit 32 , thereby preventing the peripheral wall portion 33 from opening. Outward bending deformation is restricted. Therefore, after the switch housing member 30 is attached and housed in the housing recess 20, the displacement plate 60 is prevented from coming off due to the expansion deformation of the peripheral wall portion 33 to the outside.

In this embodiment, the slit 32 is provided in the switch housing member 30 to facilitate mounting of the displacement plate 60, but the configuration is not limited to such a modified configuration. In other words, when the displacement plate 60 is not housed in the housing recess 20, the displacement plate 60 is fitted and deformed outwardly. Any other configuration may be used as long as it is held by pressure contact. For example, an elastic body such as rubber may be used to construct a structure in which the displacement plate 60 is easily mounted.
