DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
The method disclosed in No. 27419 has the following problems. (1) There is a possibility that the toilet seat 104 may fall off the main body case 101 due to the operation of the user sitting on the toilet seat 104. (2) The first bearing portion 113 of the toilet seat 104 is removably and rotatably fitted to the toilet seat shaft support projection 106 provided in the main body case 101, but is attached to the toilet seat shaft support projection 106. The insertion hole 109 is provided, and the insertion hole 10
Since the toilet lid rotary shaft 108 is inserted through the seat 9, it is necessary to form the toilet seat shaft support projection 106 itself to be relatively large.
Therefore, the first bearing portion 113 of the toilet seat 104 must be formed as a large notch. By the way, in order to be attachable and detachable, it is necessary to give elasticity to either the first bearing portion 113 or the toilet seat shaft support projection 106. However, it is necessary to give elasticity to the first bearing portion 113. As described above, since the first bearing portion 113 has to be formed as a large notch, the first bearing portion 113
It is very difficult to give elasticity while satisfying the strength required for the. Therefore, it is necessary to give elasticity to the side of the toilet seat pivot protrusion 106, but then the toilet seat pivot protrusion 106 cannot be molded integrally with the main body case 101, and therefore, due to molding tolerances. Therefore, play is generated in the mounting portion between the toilet seat shaft support projection 106 and the main body case 101. When the toilet seat is opened and closed due to this backlash, a loud noise is generated from this portion, which gives a discomfort to the user. (3) The toilet seat rotating shaft 103 and the toilet lid rotating shaft 108 are not attachable to and detachable from the toilet seat rotating device 102 and the toilet lid rotating device 107, respectively. Since the lid rotation shaft 108 projects, it is difficult to clean. (4) When the toilet seat rotating shaft 103 and the toilet lid rotating shaft 108 are configured to be detachable, the user may accidentally drop them, but since the structure pulls out toward the center of the toilet bowl,
If it falls into the toilet bowl, the toilet bowl may become clogged or the rotating shaft may disappear. (5) For cleaning, when the toilet seat 104 or the toilet lid 114 is laid down and a finger is caught in the gap between the rear end of the toilet seat 104 or the toilet lid 114 and the main body case 101, the toilet seat 104 or the toilet lid 114 is attached or detached. Since the configuration is not possible, the user may be injured.

[0004]

According to the invention of claim 1, a toilet seat device has a main body case that pivotally supports a rear end of a toilet seat and is fixedly mounted on a rear upper surface of a toilet bowl. In the above, since the restraint means for restraining the movement of the toilet seat is provided near the hinge of the toilet seat, even if the toilet seat is detachable, the toilet seat does not shift while seated, so a large load is generated at the toilet seat mounting part. Instead, it is always stable and the device body is attached to the toilet bowl so that the toilet seat device can be used with peace of mind.

In the invention of claim 2, since the restraint means is composed of the concave portion provided on the toilet seat and the convex portion provided on the main body case, the invention of claim 1 can be realized with a simple structure.

According to a third aspect of the present invention, in addition to the first or second aspect of the invention, a toilet seat coupling rotary shaft is provided so as to project from a side portion of a main body case attached to the rear portion of the toilet bowl, and the rotary shaft is attached. A toilet seat attachment / detachment restriction projection is provided around the seat, and the cross-sectional shape of the toilet seat attachment / detachment restriction projection is a non-circular cross section in which the width on one side is longer than the width on the other side, and the toilet seat is located on the rear side of the toilet seat. Providing a hinge hole to connect to the rotating shaft for coupling,
A toilet seat slip-out prevention guide having a substantially C-shaped cross section is provided around the hinge hole so that the toilet seat can be attached and detached at an angle such that a gap between the front end of the main body case and the rear end of the toilet seat is small. Since the control projection and the toilet seat slip-out prevention guide are formed, if a finger enters the gap between the rear end of the toilet seat and the main body case, the rotation shaft for connecting the toilet seat and the hinge hole will be disengaged and Since the engagement between the restriction projection and the slip-out prevention guide is also released, the toilet seat is removed from the main body case, and therefore the fingers are not caught. Further, with such a structure, the toilet seat easily comes off from the main body of the apparatus, but the restraint means does not cause the toilet seat to fall off from the main body of the apparatus by the operation of the user while the user is sitting.

In the invention of claim 4, in addition to the invention of claim 3, since the toilet seat slip-out prevention guide has an inner diameter larger than the major diameter of the toilet seat attachment / detachment restricting projection, the toilet seat slip-out prevention guide when the toilet seat is rotated. The inner diameter side does not come into contact with the long-diameter end of the toilet seat attachment / detachment restriction projection, and it is possible to prevent generation of contact noise or the like when the toilet seat rotates.

Further, in the invention described in claim 5, in addition to the invention described in claim 4, through holes are provided in the side surfaces of one side portion and the other side portion of the main body case, respectively, and each rotary shaft is provided. Is detachably attached to the toilet seat rotating device or the toilet lid rotating device through the insertion hole. Therefore, when cleaning, it is possible to remove the rotating shaft 3 for connecting the toilet seat to perform cleaning, which facilitates wiping.

Further, in the invention described in claim 6, in addition to the invention described in claim 5, the insertion holes provided on the side surfaces of one side portion and the other side portion of the body case are oriented so as not to interfere with each other. Since it is configured to be open, even if you accidentally drop it when you remove the rotating shaft for connecting the toilet seat and the rotating shaft for connecting the toilet lid, it will not fall into the toilet bowl and will be lost or will cause a toilet bowl jam. There is nothing to do.

Further, in the invention according to claim 7, in addition to the invention according to claim 6, the toilet seat attachment / detachment restricting projection is integrally formed in the main body case, and a separate part is not required. Therefore, the structure can be simplified and the cost can be reduced.

Can freely rotate between a standing posture and a falling posture. Since the width of the opening of the toilet lid removal prevention guides 15B and 16A is slightly longer than the minor diameter of the toilet lid attachment / detachment restriction projections 12A and 13C, the openings of the toilet lid removal prevention guides 15B and 16A are regulated to remove the toilet lids. The toilet lid will not come off from the toilet seat except in a posture that matches the short diameters of the protrusions 12A and 13C.

The toilet seat 4 and the toilet lid 14 attached as described above can rotate independently of each other, and like the ordinary toilet seat 4 and toilet lid 14, they can be rotated depending on the purpose of use. It is used by moving. In this case, when the toilet seat 4 is tilted, it is buffered and slowly rotated by the action of the toilet seat rotating device 2, and when the toilet lid 14 is tilted, it is buffered and slowly rotated by the action of the toilet lid rotating device 7. The impact caused by the sudden fall is eliminated, the toilet seat 4 and the toilet lid 14 are prevented from being damaged, and the impact sound when falling is prevented.

By the way, at the time of cleaning, the toilet seat 4 and the toilet lid 14 are removed for cleaning. In this case,
The toilet seat 4 and the toilet lid 14 are removed as follows. That is, the toilet seat 4 and the toilet lid 14 are removed in the reverse order of the mounting order of the toilet seat 4 and the toilet lid 14. First, with the toilet seat 4 tilted down, tilt only the toilet lid 14 forward,
In this state, only the toilet lid 14 is pulled up. Then, with the toilet seat 4 tilted down, the toilet lid attaching / detaching restriction projection 12A,
Since the long diameter side of 13C is set so as to face obliquely forward or obliquely upward, by opening only the toilet lid 14 in a forward tilted position, the opening of the toilet lid removal prevention guide having a substantially C-shaped cross section is directed downward. In this state, by pulling only the toilet lid 14 upward, the second attaching / detaching portion 15b and the second attaching / detaching portion 15b
The bearing portions 16a of the above can be pulled out upward from the toilet lid coupling portion 10 and the toilet lid rotating shaft portion 12a, respectively.

After removing the toilet lid 14 in this manner,
The toilet seat 4 is rotated to a forward tilted posture, and in this state, the toilet seat 4 is pulled up.

The opening portions of the slip-out prevention guides 11A and 13B face downward, and in this state, the toilet seat 4 is pulled up, whereby the first attaching / detaching portion 11a and the first attaching / detaching portion 11a.
The bearing portions 13b of the above can be pulled out upward from the attachment / detachment portion and the rotary shaft, respectively.

In this way, the toilet seat 4 and the toilet lid 14 are removed for cleaning. In this case, the side wall portions 20a and 20b of the protruding portion 20 of the main body case 1 are used to rotate the toilet seat coupling rotary shaft 3.
Since it is not necessary to remove the rotary shaft 8 for connecting the toilet lid or the toilet lid, the holes into which the rotary shaft 3 for connecting the toilet seat and the rotary shaft 8 for connecting the toilet lid are not opened, and therefore the toilet seat connecting shaft is attached during cleaning. Water does not enter the inside of the main body case 1 through the hole after the rotary shaft 3 and the toilet lid coupling rotary shaft 8 are pulled out, and the electric components and the like inside the main body case 1 do not adversely affect the water. There is no such thing as receiving.

By the way, as described above, the toilet seat 4 and the toilet lid 14 are provided.
Of the toilet seat rotating device 2 and the toilet lid rotating device 7 when they are tilted, respectively.
Since the shaft-supporting part of is located on the same axis, the structure of the shaft-supporting part becomes compact. Further, even when the toilet seat 4 and the toilet lid 14 are removed for cleaning, in the present invention,
Only the toilet seat coupling rotary shaft 3, the toilet lid coupling rotary shaft 8, and the toilet seat attachment / detachment restricting protrusions 6a and 6b are located on the side wall portions 20a and 20b of the protrusion 20 of the main body case 1. Since the use rotary shaft 8 and the toilet seat rotary shaft portion 3 are located on the same axis, the shaft support member is less likely to get in the way during cleaning, and cleaning can be performed easily.

It is needless to say that the present invention is not limited to the above-described embodiments and can take other forms as long as the effects of the invention are not impaired. For example, toilet seat 4
The toilet lid attachment / detachment restricting protrusion 12A provided on the seat cover can be used as a toilet lid shaft stopping protrusion to remove the toilet lid rotation shaft portion 12a. Further, at the expense of the difficulty of cleaning due to the protrusion of the toilet seat coupling rotary shaft 3 and the toilet lid coupling rotary shaft 8, the toilet seat coupling device is detachable from the toilet seat rotation device 2 and the toilet lid rotation device 7. The toilet seat coupling rotary shaft 3 and the toilet lid coupling rotary shaft 8 may not be removable. Further, at the sacrifice that the toilet seat coupling rotary shaft 3 and the toilet lid coupling rotary shaft 8 fall into the toilet bowl, the protrusions 20 of the main body case 1 are not formed in the center, but interfere with each other. It may be formed separately on both sides. In addition, the toilet seat removal prevention guide and the toilet lid removal prevention guide are not necessarily limited to the C-shaped cross section, and any guides that prevent the removal of the toilet seat removal in the circumferential direction around the rotation axis may be used. It is also conceivable to provide a plurality of protrusions in the circumferential direction.
