[Problems to be solved by the invention] Toilet seat 52 and toilet lid 53
Is a member to which a person sits or is exposed to dust, and thus is easily contaminated. In particular, in the case of a sanitary washing device, splashes or the like during local washing often adhere to the toilet seat 52. For this reason, when wiping and cleaning the toilet seat 52 and the toilet lid 53, it is difficult to perform the operation while being connected to the casing 51, and it is necessary to remove the toilet seat 52 and the toilet lid 53.

However, in order to pull out the hinge shaft 54, a tool such as a screwdriver is required when the flange 54a is pulled out from the fixed seat 52c. For this reason, a general housewife or the like is unfamiliar with the handling of the tool, so that even if the user intends to clean the corner, the hinge shaft 54 cannot be pulled out and often ends as it is.

If the hinge shaft 54 is forcibly pulled out, not only the hinge shaft 54 itself but also the mounting holes 52b, 53
There is also a high possibility that b and the fixed seat 52c will be damaged. For this reason, even if the user tries to connect the toilet seat 52 and the toilet lid 53 to the casing 51 again, the hinge shaft 54 loses its proper function, and the opening and closing operation of the toilet seat 52 and the toilet lid 53 causes backlash and the like. Results.

Thus, in the conventional connection structure, the toilet seat 5
2 and the toilet lid 53 cannot be easily removed from or connected to the casing 51, and there is a problem that cleaning of these members tends to be insufficient.

The problem to be solved in the present invention is to enable the toilet seat and the toilet lid to be attached to and detached from a casing such as a multifunctional toilet seat device by simple handling.

[0014]

The present invention is a toilet seat device in which a functional portion is housed in a casing, and a toilet seat and a toilet lid are attached to the casing so as to be openable and closable. At the base end, a pair of mounting seats for connecting to the casing are provided at intervals in the width direction, and one of the mounting seats of the toilet seat or the toilet lid is provided with a pair of hinge pins protruding in the width direction, The casing is provided with a pair of connection holes through which the hinge pin can be inserted, and an elastic pressure receiving mechanism that receives the tip of the inserted hinge pin in the axial direction is provided inside the casing at a position facing one of the connection holes, It is characterized in that at least one of the mounting seats of the toilet seat or the toilet lid not having a hinge pin is provided with a detachable holding hole with a slit around the hinge pin. To.

[0015]

When a hinge pin is provided on the mounting seat of the toilet seat, the mounting seat of the toilet lid is provided with a mounting hole on the side of the elastic pressure receiving mechanism, and the other mounting seat is provided with a holding hole with a slit. When the hinge pin of the toilet seat is inserted into the mounting hole of one mounting seat of the toilet lid, and the other hinge pin is fitted into the holding hole of the other mounting seat through a slit, the toilet lid and the toilet seat are integrated. At this time, if the mounting hole and the holding hole are freely rotatable relative to the hinge pin, not only the rotation operation but also the hinge pin can move through the mounting seat on the toilet lid side in the axial direction. Therefore, when one hinge pin is inserted into the connection hole facing the elastic pressure receiving mechanism, the elastic pressure receiving mechanism is pushed by the hinge pin, and the other hinge pin can be placed at a position just before the other side of the connection hole. Become.

If the toilet seat and the toilet lid are released after such an operation, the reaction force of the elastic pressure receiving mechanism also helps to push one of the hinge pins, and inserts the other hinge pin into the connection hole on the other side. Can be.

Therefore, by inserting the hinge pin on the elastic pressure receiving mechanism side into the connecting hole and then shifting the toilet seat and the toilet lid toward the elastic pressure receiving mechanism, the hinge pin on the other side can be inserted into the other connecting hole. Becomes Also, the toilet seat and the toilet lid are shifted to the elastic pressure receiving mechanism side, the other hinge pin is first pulled out from the connection hole, and then the hinge pin on the elastic pressure receiving mechanism side is pulled out from the connection hole, thereby removing the toilet seat and the toilet lid from the casing. It becomes possible.

FIG. 1 is a perspective view of a sanitary washing device provided with a toilet seat and toilet lid mounting structure according to the present invention installed on a toilet body.

In the figure, a toilet body 50 is provided on the casing 2 of the sanitary washing device 1 by using the upper surface of a rim on the back side thereof.
The toilet seat 3 and the toilet lid 4 are respectively attached to the casing 2 so as to be freely opened and closed.

The sanitary washing device 1 is a water supply heating system for heating and supplying washing water to the inside thereof. In use, the nozzle device dives under the toilet seat 3 to advance to the ball portion of the toilet body 50 to spray the washing water. It incorporates a controller 1a and a controller for controlling each functional unit, and can replace a conventionally used one as it is. The operation of the functional unit is performed by the operation panel 1b provided on the side of the casing 2.

FIG. 2 shows a casing 2 to a toilet seat 3 and a toilet lid 4.
It is the disassembled perspective view which removed.

A pair of mounting seats 3a and 3b are provided at the base end of the toilet seat 3 near the left and right ends so as to protrude toward the back. These mounting seats 3a, 3b have hinge pins 3c, 3c projecting outward with a substantially horizontal axis.
3d are provided coaxially. When the toilet seat 3 is viewed from the front side, the hinge pin 3c of the mounting seat 3a located on the left side is different from the hinge pin 3 provided on the mounting seat 3b on the right side.
It is assumed that it is slightly longer than d.

On the other hand, similarly to the toilet seat 3, a pair of mounting seats 4a and 4b are provided on the base end portion of the toilet lid 4 so as to protrude rearward at portions close to both right and left ends. These mounting seats 4a, 4b
Are longer than those of the mounting seats 3a and 3b on the toilet seat 3 side. When the toilet lid 4 is put on the toilet seat 3, the mounting seats 3a and 3b of the toilet seat 3 are attached to the mounting seats 4a and 4b of the toilet lid 4. It becomes the arrangement sandwiched by. When the toilet lid 4 is viewed from the front side, a hinge pin 3 is provided on the mounting seat 4a located on the left side.
Then, a mounting hole 4c having an inside diameter enough to insert the c and rotate while contacting the peripheral surface of the hinge pin 3c is opened. On the other hand, the mounting seat 4b located on the right side cuts the slit 4d upward from the lower end thereof. This slit 4d is detachable on the outer periphery of the hinge pin 3d,
A holding hole 4e having a substantially circular opening that fits the outer peripheral surface of the hinge pin 3d when attached is formed continuously.

On the front surface of the casing 2, a hinge chamber 2a for accommodating the base ends of the toilet seat 3 and the toilet lid 4 is provided so as to be recessed toward the back. In addition, connecting holes 2c and 2d for inserting hinge pins 3c and 3d integrated with the toilet seat 3 are formed coaxially in a holding wall 2b that partitions the left and right sides of the hinge chamber 2a. These connecting holes 2c, 2d have an inner diameter and an axial length that can support the hinge pins 3c, 3d so as to be rotatable by restraining the outer peripheral surfaces thereof.

FIG. 3 shows the toilet seat 3 and the toilet lid 4 connected to the casing 2.
FIG. 5 is a cross-sectional view taken along a plane including the axis of the hinge pins 3c and 3d when the hinge pins 3c and 3d are connected.

An elastic pressure receiving mechanism E for elastically receiving the hinge pin 3c is provided in the casing 2 on the side where the left hinge pin 3c is inserted through the connection hole 2c, substantially coaxially with the insertion direction of the hinge pin 3c. This elastic pressure receiving mechanism E
A case block 5 fixed in the casing 2;
In this case block 5, a receiving hole 5a having an inner diameter into which the hinge pin 3c can be inserted is opened, and a slider 5b is incorporated therein. The slider 5b is slidable inside the case block 5 like a piston, and its sliding direction is made to coincide with the direction in which the hinge pin 3c is moved in and out of the receiving hole 5a. Further, a spring 5c is further housed inside the case block 5, thereby urging the slider 5b in the direction of the receiving hole 5a.

In the above configuration, the operation of connecting the toilet seat 3 and the toilet lid 4 to the casing 2 is as follows.

First, the hinge pin 3c on the left side of the toilet seat 3 is inserted into the mounting hole 4c of the toilet lid 4 while aligning the base ends of the toilet seat 3 and the toilet lid 4. Next, the toilet lid 4 is put on the toilet seat 3, and the slit 4 d of the mounting seat 4 b of the toilet lid 4 is provided.
Is placed on the hinge pin 3d of the toilet seat 3 and pressed down. Due to this reduction, the slit 4d is elastically deformed in a direction of expanding around the peripheral surface of the hinge pin 3d, and the hinge pin 3d enters the holding hole 4e beyond the slit 4d. By this assembly, the toilet seat 3 and the toilet lid 4 are connected with the hinge pins 3c and 3d, the mounting holes 4c and the holding holes 4e, and the toilet lid 4 can freely move around the hinge pins 3c and 3d.

For connection to the casing 2, the hinge pin 3c on the left side of the toilet seat 3 is inserted into the connection hole 2c, and the tip of the hinge pin 3c is inserted into the case block 5 from the receiving hole 5a. Then, the toilet seat 3 and the toilet lid 4 are pushed to the left with respect to the casing 2 so that the hinge pin 3c enters the case block 5 further deeply. Thus, the slider 5b in the case block 5 moves to the left in FIG. 3 while contracting the spring 5c.

Here, when the hinge pin 3c is inserted into the case block 5, the amount that can be moved to the left is
And the toilet lid 4 are once slightly deviated to the left of the center of the casing 2, and the hinge pin 3 d on the right is
The distance can be set to a position that does not interfere with the holding wall 2b on the right side of FIG. In this way, when the hinge pin 3c is inserted deeply into the case block 5, the other hinge pin 3d can be dropped into the hinge chamber 2a. Then, when the hinge pin 3d is aligned with the connection hole 2d and the toilet seat 3 and the toilet lid 4 are freed and slightly moved to the right, the hinge pin 3d enters the connection hole 2d. At this time, the restoring force of the spring 5c also acts to push the toilet seat 3 and the toilet lid 4 to the right, so that the toilet seat 3 and the toilet lid 4 are naturally connected to the casing 2. Therefore, the hinge pins 3c, 3d are rotatably restrained in the connection holes 2c, 2d, and the toilet seat 3 and the toilet lid 4
Are connected to the casing 2 at the same time.

After the hinge pins 3c and 3d are connected to the casing 2, the elastic force of the spring 5c is applied to the slider 5b.
And acts on the hinge pin 3c through. For this reason, the hinge pin 3c is restrained in its axial position, and the toilet lid 3 connected to the toilet seat 3 by the toilet seat 3 and the hinge pins 3c, 3d is held without rattling in the left-right direction. Therefore, the opening / closing operation of the toilet seat 3 and the toilet lid 4 is performed quickly, and the hinge pin 3c is elastically supported, so that even if an external force is applied to the toilet seat 3 or the toilet lid 4, it can be buffered. Damage to the members is also prevented.

To remove the toilet seat 3 and the toilet lid 4 from the casing 2, the toilet seat 3 and the toilet lid 4 are pushed to the left as viewed from the front. As a result, the hinge pin 3c pushes the slider 5b and moves it to the left, whereby the toilet seat 3 and the toilet lid 4 move from the center of the casing 2 to the left. Therefore, the amount of this movement is controlled by the other hinge pin 3d by the connection hole 2d.
If it is enough to get out of d, the hinge pin 3d
Can be removed from the connection hole 2d. As a result, the hinge pin 3d that restrains one of the toilet seat 3 and the toilet lid 4 toward the casing 2 becomes free, and if the other hinge pin 3c is pulled out from the connection hole 2c as it is, the toilet seat 3 and the toilet lid 4 are simultaneously placed in the casing. 2 can be removed.

In this manner, the toilet seat 3 and the toilet lid 4 can be easily attached and detached from the casing 2 by simply pushing the integral part of the toilet seat 3 and the toilet lid 4 slightly to the left with respect to the center of the casing 2. It is possible to do. Therefore, when cleaning the toilet seat 3 and the toilet lid 4, they can be removed and wiped all over, and the surface of the casing 2 can be kept clean.

FIG. 4 is a schematic plan sectional view of a main part showing connection to the casing 2 in an example in which the mounting seats 4a and 4b of the toilet lid 4 are arranged inside the mounting seats 3a and 3b of the toilet seat 3.

On the seats 3a, 3b of the toilet seat 3, pivot pins 3e, 3f protrude inward, respectively, coaxially with the hinge pins 3c, 3d, and the seats 4a of the toilet lid 4 are fixed by these pivot pins 3e, 3f. , 4b are rotatably connected. The mounting hole 4c of one mounting seat 4a of the toilet lid 4 is formed by penetrating the mounting seat 4a as in the case of FIG. 2, and the other mounting seat 4b is similarly formed by the slit 4d and the holding hole 4e. . Note that the axial length of the hinge pin 3c and the positional relationship with the slider 5b are determined by the hinge pin 3c.
It is a matter of course that the other hinge pin 3d can be inserted into the connection hole 2d when the is inserted into the elastic pressure receiving mechanism E.

The rest of the structure is exactly the same as that of the above embodiment, and the toilet lid 4 is integrated with the toilet seat 3 in advance.
Connect one hinge pin 3c to the connecting hole 2c on the elastic pressure receiving mechanism E side.
And then insert the other hinge pin 3d into the mounting hole 2d.
It can be assembled by plugging in.

FIG. 5 shows still another embodiment.
The toilet seat 3 and the toilet lid 4 are provided at both ends of the casing 2 in the width direction.
Are mounted to connect the mounting seats 3a to 4b.

At both ends of the casing 2 in the width direction, connection seats 2e and 2f whose corners are cut are provided, and mounting holes 2g and 2h are opened respectively. An elastic pressure receiving mechanism E is incorporated on the mounting hole 2g side.

Hinge pins 4f and 4g are provided on the mounting seats 4a and 4b of the toilet lid 4 so as to protrude inward, and mounting holes 3g and holding holes for inserting these hinge pins 4f and 4g are provided on the mounting seats 3a and 3b of the toilet seat 3. Open 3h. Holding hole 3h
As in the case of the toilet lid 4 shown in FIG. 2, the slit 3i is incised to the lower end, and the hinge pin 4g can be fitted into the mounting hole 3g from the slit 3i.

Also in this example, the toilet seat 3 and the toilet lid 4 are connected in advance by hinge pins 4f, 4g, mounting holes 3g, and holding holes 3h, and one hinge pin 4f is inserted into the mounting hole 2g of the connecting seat 2e, and the case block is closed. 5 sliders 5
The toilet seat 3 and the toilet lid 4 can be connected to the casing 2 by inserting the other hinge pin 4g into the other mounting seat 2h while pressing b.
