[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat device in which electric toilet components are housed in a casing, and more particularly to a structure for mounting a toilet seat and a toilet lid connected to the casing via a mechanism for gently closing the toilet seat.

[0002]

2. Description of the Related Art A warm water flush toilet seat having a local flushing function is provided with a local flushing function, a deodorizing function, a toilet seat heating function, etc. collectively in a casing, and a toilet seat and a toilet lid are connected to this casing and installed on a toilet. The thing is its general configuration.

On the other hand, a structure in which a resistance is applied to the rotation of the hinge mechanism when the toilet seat and the toilet lid are closed, and the hinge mechanism is gently operated has been conventionally used. As such an opening / closing mechanism, there is a mechanism described in Japanese Patent Application Laid-Open No. 2-63424, for example, in which an opening / closing unit for inserting a hinge shaft of a toilet seat and a toilet lid is provided, and a resistance mechanism and the like are provided in the opening / closing unit. Incorporated structures are commonly employed.

However, since various functional parts are laid out in the casing, if the opening / closing unit is to be housed in the casing, the degree of freedom in layout is reduced and the casing is also enlarged.

Suggested by.

As described above, the provision of the opening / closing unit in each of the toilet seat and the toilet lid makes it unnecessary to incorporate a resistance mechanism into the casing, and eliminates layout interference with a functional portion in the casing. Also, by making the opening / closing unit detachable from the casing side,
There is also an advantage that cleaning and maintenance and inspection of the toilet seat and the toilet lid including the casing are simplified.

[0007]

The attachment and detachment of the toilet seat and the toilet lid to and from the casing are performed via opening / closing units provided at respective base ends and a retainer block for connecting these to the casing. Therefore, the toilet seat and the toilet lid each have a dedicated opening / closing unit and a retainer block, and a total of four members are attached to the toilet seat and the toilet lid.

When the number of members is large, the opening / closing unit may come off from the toilet seat or the lid when being removed from the casing during cleaning or the like, and may be detached together with the retainer block. If the members are detached in this way, it is difficult for housewives and the like to determine how to incorporate the four members into the toilet seat and the toilet lid, and the product lacks some suitability as a general product. .

The problem to be solved in the present invention is to prevent the opening / closing unit from easily coming off from the toilet seat or the toilet lid, and to be able to handle the opening / closing unit without being confused by attaching / detaching to / from the casing.

Is done.

Here, it is assumed that, for example, the retainer block 7 arranged on the left side has come off during the extraction operation. In this case, the coupling shaft 7a comes out of the coupling hole 5b of the opening / closing unit 5, and the engaging arm 6c comes out of the holding hole 7b and is separated. On the other hand, the opening / closing units 5 and 6 in the unit chambers 3b and 4b are prevented from moving to the left and right, respectively, and the opening / closing units 5 and 6 are kept at the position shown in FIG. Therefore, the retainer block 8 arranged on the right side maintains the connection to the opening / closing units 5 and 6 unless the retainer block 8 is strongly pulled. Therefore, the retainer block 8 does not come off, and the toilet seat 3 and the toilet lid 4 are maintained in an integrated state by the retainer block 8.

Conversely, when the retainer block 8 arranged on the right side comes off, the opening / closing unit 6 is held in the unit chamber 4b by the retainer block 7 arranged on the left side. Then, with respect to the opening / closing unit 5 for the toilet seat 3, the connecting shaft 7a of the retainer block 7 is merely fitted in the connecting hole 5b, but the movement to the left is restricted by the protrusion 5e. Therefore, the unit does not fall out of the unit chamber 3b unless a large external force acts. Therefore, the two opening / closing units 5 and 6 are used as
And the toilet seat 4 and the toilet seat 4
Are not separated by the retainer block 7.

Further, when both the retainer blocks 7 and 8 come off, the toilet seat 3 and the toilet lid 4 are separated, but unless a large external force acts in the direction in which the opening / closing units 5 and 6 are pulled out. These do not fall out of the toilet seat 3 and the toilet lid 4. For this reason, even if the retainer blocks 7 and 8 are connected to the opening and closing units 5 and 6 and reassembled,
There is no difficulty in the work.
