The switch accommodating member 30 has an oblong shape in a plan view, and has a accommodating space 31 for accommodating the switch body 51 of the seating switch 50, and a peripheral wall portion 33 is formed to surround the accommodating space 31. The peripheral wall portion 33 is broken by a slit 32 (a longitudinal opening that forms an opening both up and down) extending in the vertical direction. This slit 32 is formed at one end side of the switch storage member 30 in the longitudinal direction. In short, the slit 32 is opened by this to expand the slit The two sides of the peripheral wall portion 33 that are cut off in the manner of 32 can be flexed and deformed outward with the other end side in the longitudinal direction as a fulcrum.

In addition, the peripheral wall portion 33 is a double wall for reducing weight, and in the interior surrounded by the peripheral wall portion 33, a storage space 31 with a bottom having a rectangular shape in plan view whose outer shape depends on the inner edge of the peripheral wall portion 33 is formed. As shown in Figs. 3 and 4, the storage space 31 includes the following components for positioning and fixing the switch body 51 (illustrated by a two-dot lock line in Fig. 4): short-side fixing portions 37 facing each other , The longitudinal direction fixing portion 38, and the claw piece portion 39 that presses the switch body 51 from above.

In addition, on the inner side (top of the inner wall surface) of the peripheral wall portion 33 of the switch housing member 30, a protrusion 34 is arranged to lock the long side edge portions 63a (peripheral edge portions 63) of the displacement plate 60 on both sides facing each other. Furthermore, a locking portion 35 is disposed at a position (short side) facing the slit 32 of the peripheral wall portion 33 to lock the short edge portion 63b (peripheral edge portion 63) of the displacement plate 60. As shown in FIG. 5, guide surfaces 34a, 35a inclined downward toward the storage space 31 side are formed on the top surfaces of the protrusion 34 and the locking portion 35.

By inserting the peripheral edge portion 63 of the displacement plate 60 into the gap between the protruding portion 34 and the locking portion 35 and the convex portion 36, the displacement plate 60 is fixed and locked.

The bottom plate 42 provided below the storage space 31 has an opening formed in a part of the slit 32 side (one end side in the longitudinal direction), and the opening 43 communicates with the slit 32, and the continuous opening 44 passes through the storage recess The bottom opening 25 of the 20 (refer to FIG. 2) communicates with the interior 11 of the toilet seat body 10. Also, in the bottom plate portion 42 A recessed opening 42a is formed on the edge of the slit 32 side, and a part of the bottom of the switch body 51 is arranged to protrude below the opening 43 and the recessed opening 42a.

In addition, the above-mentioned flange pieces 40 are provided separately at four positions on the outer surface of the peripheral wall portion 33. At a position below this flange piece 40, a foot portion 41 corresponding to the broken peripheral wall portion 33 is formed (see FIGS. 4 and 5). Therefore, the foot portion 41 is integrated with the peripheral wall portion 33 and flexed and deformed.

As described above, in a state in which the switch storage member 30 is correctly stored in the storage recess 20, the foot portion 41 is in a state of being clamped from both outsides by the clamping portion 23 (refer to FIG. 4). That is, when the switch storage member 30 is in the storage state, the outer flexural deformation of the peripheral wall portion 33 and the foot portion 41 is restricted by the clamping portion 23.

Next, the installation procedure of the seating switch 50 (switch body 51 and the displacement plate 60) with respect to the switch storage member 30 will be described with reference to FIGS. 5 to 7.

First, the conductive wire 12 is temporarily stored in the back plate portion 13. At this time, one end of the conductive wire 12 is taken out from the hinge part of the toilet seat device 1, and the other end is temporarily stored in the vicinity of the storage recess 20. In this state, the back plate portion 13 and the front plate portion are welded. Next, from the storage recess 20 provided in the back plate portion 13, the conductive wire 12 stored inside is taken out. Next, the conductive wire 12 taken out from the inside 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 stored in the switch housing member 30. Storage space 31 (refer to FIG. 5).

Since the opening area of the receiving recess 20 is sufficiently larger than the cross-sectional area of the switch body 51, the following operations can be easily performed: taking out the conductive wire 12 from the interior 11 of the toilet seat body 10, and connecting the switch body 51 with the conductive wire 12 The storage operation in the interior 11. Moreover, since the embodiment of the present invention connects the slit 32 with the opening 43 on the bottom side to form a larger continuous opening 44, it is particularly easy to store the switch body 51 connected with the conductive wire 12 into the storage space 31 Homework.

Next, the installation procedure of the displacement plate 60 will be described. The displacement plate 60 is composed of the following: an action spring plate 61 that is elastically displaced downward to contact the detection portion 52 of the switch body 51 (refer to FIG. 6); and a support spring plate 62 overlapping the action spring The top surface of the plate 61 (refer to FIG. 7). Any spring plate is composed of a slightly rectangular thin plate whose outer shape matches the top-view shape of the opening of the storage space 31.

The action spring plate 61 has a rectangular action piece 61a formed in the center, and a holding piece 61b for holding the action piece 61a is formed around the action piece 61a with a gap generated by cutting or the like; the action piece 61a is short The size of the side is small, and only a short side is connected to the surrounding, and the long side becomes a long strip, which is easy to bend. In addition, the support spring plate 62 is not processed with a gap or the like.

As shown in FIGS. 6 and 7, such a displacement plate 60 only needs to be installed one piece at a time in the order of the action spring plate 61 (refer to FIG. 6) and the support spring plate 62 (refer to FIG. 7). Of course, two pieces can also be stacked for installation.

The operating spring plate 61 is inserted into the gap between the locking portion 35 and the convex portion 36 provided on the inner wall surface of the peripheral wall portion 33 by the operator inserting the peripheral edge portion 63 (short edge portion 63b) on the fulcrum side of the operating spring plate 61 , And temporarily solid Hold in an oblique shape. Next, by pressing the slanted top of the action spring plate 61 downward, the peripheral edge portion 63 (both long side edge portions 63a) over the lower part of the protrusion 34 (the storage space 31 side), and the action spring plate 61 is inserted into Between the protruding portion 34 and the convex portion 36. In this way, the action spring plate 61 is arranged and held in an appropriate position in the storage space 31.

In the same way, the support spring plate 62 is temporarily installed by the operator on one side of the peripheral edge portion 63 (short side edge portion 63b) in the gap between the locking portion 35 and the action spring plate 61 in contact with the convex portion 36. Hold in a slanted shape. Then, by pressing the inclined top of the support spring plate 62 downward, the peripheral edge portion 63 (the two long side edge portions 63 a) is inserted between the protrusion portion 34 and the action spring plate 61 over the protrusion portion 34. In this way, the support spring plate 62 is arranged and held in an appropriate position in the storage space 31.

Since the peripheral wall portion 33 is broken by the slit 32, the displacement plates 60 can be installed without difficulty. That is, when the displacement plate 60 is inserted, the peripheral edge portion 63 of the displacement plate 60 passes over the protrusion 34 toward the storage space 31, and along with this, the both sides of the broken peripheral wall portion 33 move away from each other. The outside is flexed and deformed. Then, the flexural deformation is complemented by the action generated by the guide surface 34a of the protrusion 34, so that the peripheral edge portion 63 can easily pass over the protrusion 34. In this way, like the switch body 51, the displacement plate 60 can also be easily mounted to the switch receiving member 30.

Moreover, in the embodiment of the present invention, since the inner edge of the peripheral wall portion 33 has a slightly rectangular shape in plan view, and the slit 32 is provided on the short side of one of the rectangular sides, both sides of the peripheral wall portion 33 on the long side The side portion is easily flexed and deformed, which makes the installation of the displacement plate 60 easier.

In addition, as in the embodiment of the present invention, the protrusion 34 is provided at a position near the slit 32, and the locking part 35 is provided at a position opposite to the slit 32. It is expected that the displacement plate 60 can be clamped in a well-balanced manner. only. Moreover, as shown in FIG. 5 and FIG. 6, by arranging the protruding portion 34 and the locking portion 35 in this way, the displacement plate 60 can be easily attached by rotating the locking portion 35 side as a fulcrum. In addition, the formation position or number of the protruding portion 34 or the locking portion 35 is not limited to the embodiment of the present invention. The protruding portion 34 and the locking portion 35 only need to be two or more in total, and may be provided one on each side.

In this way, in the switch storage member 30, the switch body 51 and the displacement plate 60 to which the conductive wire 12 is connected are appropriately installed in the storage space 31. The switch storage member 30 in this state can be directly stored in the storage recess 20 of the toilet seat body 10.

In this way, in the toilet seat device 1 of the present invention, the seat switch 50 (switch body 51) does not need to be directly stored in the receiving recess 20, but can be stored in the switch receiving member 30 in a state where it is attached to the member. Matching storage recess 20 with larger opening. Therefore, the performance has become much better than before.

In addition, since the continuous opening 44 including the slit 32 provided in the switch receiving member 30 communicates with the bottom opening 25 provided in the receiving recess 20 leading to the interior 11 of the toilet seat body 10, it can also be easily connected The conductive wire 12 is installed back into the inner portion 11.

In addition, if the switch storage member 30 is stored in the storage recess 20, the foot 41 is clamped by the clamping portion 23 (refer to FIG. 2) formed in the storage recess 20, thereby restricting the expansion of the slit 32 and thereby restricting Toward 33 of the peripheral wall Deflection and deformation of the outside. Therefore, after the switch storage member 30 is installed and stored in the storage recess 20, it is possible to prevent the displacement plate 60 from falling off due to expansion and deformation to the outside of the peripheral wall portion 33.

In addition, in the embodiment of the present invention, the slit 32 is provided in the switch receiving member 30 to facilitate the installation of the displacement plate 60, but it is not limited to such a deformed structure. In short, as long as the system is not stored in the storage recess 20, it will be flexed and deformed outward due to the insertion of the displacement plate 60, and in the state of being installed and stored in the storage recess 20, the flexural deformation will be restricted, and The displacement plate 60 is held by crimping, and other configurations are also possible. For example, it may be a structure in which the displacement plate 60 can be easily installed by using an elastic body such as rubber.
