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, and the like in a casing, and a toilet seat and a toilet lid are connected to the casing in a freely slidable manner. Is a 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 to operate slowly is also conventionally used. As such an opening / closing mechanism, there is, for example, a mechanism described in Japanese Patent Application Laid-Open No. 2-63424. An opening / closing unit for inserting a hinge shaft of each of a toilet seat and a toilet lid is provided, and a resistance mechanism is provided in the opening / closing unit. Incorporated structures are commonly employed.

However, due to the layout of various functional parts in the casing, if the opening and closing unit is to be housed in the casing, the degree of freedom in layout is reduced, and the casing becomes larger. On the other hand, the applicant of the present invention has previously disclosed a configuration in which an opening / closing unit is built in each of the base ends of the toilet seat and the toilet lid, and the opening / closing unit is fitted into the casing so as to be detachable by adopting a fitting method. No. 4-91143.

As described above, by providing the opening and closing unit in each of the toilet seat and the toilet lid, it is not necessary to incorporate a resistance mechanism in the casing, and it is possible to eliminate the interference of the layout with the functional portion in the casing. Further, by making the opening / closing unit detachable from the casing side, there is an advantage that cleaning and maintenance and inspection of the toilet seat and the toilet lid including the casing can be easily performed.

[0005]

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, each of the toilet seat and the toilet lid has 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. In the structure in which the toilet seat and the toilet lid are attached to the casing by the fitting method using such a retainer block, as described above, the toilet seat and the toilet lid can be easily removed from the casing, but the toilet seat and the toilet lid can be easily removed. When in the closed position, or when the toilet lid is raised and properly seated on the toilet seat, no force is applied to the retainer block in the direction of removal from the casing, and the toilet seat is stable at the base end of the casing. Is maintained.

On the other hand, when the toilet seat is closed between the toilet seat and the upper surface of the toilet seat, the toilet seat is bufferedly received by the toilet seat (the toilet seat has a predetermined space with respect to the toilet bowl). 4) Four supporting rubber legs are attached.
These legs are usually mounted at positions where a cushioning action occurs when the user sits on the toilet seat, and the mounting location is from the center of the toilet seat in the front-rear direction and from the center in the front-rear direction. It is installed in a close position that is not too far away. For this reason, when sitting on the toilet seat, the cushioning action is caused by the bending of the rubber, and the seat is comfortable. In addition, since the toilet seat is held in a floating state due to the presence of the legs, it is possible to prevent moisture adhering to the upper surface of the toilet bowl from entering the toilet seat.

However, when the toilet seat is closed (mounted on the upper surface of the toilet bowl), if the user accidentally sits on the front side of the toilet seat farthest from the base end of the toilet seat or attempts to sit down with his / her hand, Due to the action of the lever with the legs attached to the near side as a fulcrum, an excessive upward acting force acts on the retainer block. As a result, since the retainer block fitted into the mounting seat of the casing may move upward and float, the user who takes time and effort to correctly sit on the toilet seat, such as a disabled person, a child, the elderly, etc. When the above problem occurs, there is a possibility that discomfort and anxiety may be caused when using the Western style toilet. Therefore,
Even though the use of the retainer block makes it easy to remove the toilet seat from the casing, there is still a problem that the toilet seat may come off the casing depending on how the seat is improperly seated. .

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a toilet seat device in which a toilet seat and a toilet lid are detachably attached to a casing via a retainer block. It is an object of the present invention to provide a toilet seat mounting structure that reliably prevents a retainer block from unnecessarily moving up and coming out of a casing even if the user sits in a state or an external force is applied.

[0009]

SUMMARY OF THE INVENTION The present invention is directed to a toilet seat device in which electrical components of a toilet bowl are housed in a casing, and a toilet seat and a toilet lid are slidably attached to the casing, and a hinge chamber recessed in the casing. An opening / closing unit housed in a hinge block provided at a base end portion of each of the toilet seat and the toilet lid and having a built-in mechanism for providing resistance when closing the toilet seat and the toilet lid, and a resistance mechanism of the opening / closing unit. A retainer block coupled to the hinge chamber and fixed to the hinge chamber, the toilet lid is mounted on the upper surface of a toilet bowl, and the toilet seat is seated in an abnormal posture such as a forward inclination, or a front side of the toilet seat. When the base end of the toilet seat receives an upward acting force, for example, when the user pushes strongly, the hinge block on the toilet seat side is locked and held on the hinge chamber side, and the hinge Characterized by being configured to restrain the click upward movement.

When the toilet seat is placed on the upper surface of the toilet bowl, a laterally elongated locking ridge is projected along the axial direction of the hinge block at a position corresponding to the hinge chamber on the outer periphery of the hinge block of the toilet seat. In the hinge chamber of the casing corresponding to the locking ridge, a locking step for locking and unlocking the locking ridge is provided, and the locking ridge is locked and held by this locking step. The hinge block of the toilet seat is configured to be prevented from moving upward by an external force.

[0011]

According to the present invention, as described above, when the toilet seat is mounted on the upper surface of the toilet, the user can sit leaning on the front side of the toilet seat or move the front of the toilet seat to the toilet side. When the toilet seat is strongly pressed, the toilet seat receives the upward acting force on the base end side by the lever action with the leg attached to the back surface on the front side as a fulcrum. At this time, since the hinge block of the toilet seat is restrained so as not to move upward in the hinge chamber, the base end of the toilet seat may unnecessarily move up or out of the casing due to abnormal handling such as seating. The problem can be solved reliably.
