DETAILED DESCRIPTION OF THE INVENTION

[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 accommodated 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.

On the other hand, the present applicant has previously disclosed a structure in which an opening / closing unit is built in the base end of each of the toilet seat and the toilet lid, and these opening / closing units are detachable in a casing. No. 91143.

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.

In the structure in which the toilet seat and the toilet lid are attached to the casing using such a retainer block, the toilet seat and the toilet lid can be easily removed from the casing as described above. On the other hand, in the case where the toilet seat and the toilet lid are closed,
No acting force is generated on the retainer block in the direction of removal from the casing, and the retainer block is stably held.

However, when the toilet seat or the lid is raised and held at a predetermined stop angle, if these are erroneously pushed to increase the rising angle, an excessive upward acting force acts on the retainer block. Become. For this reason, the retainer block dropped into the mounting seat of the casing moves upward and the operation becomes unstable. Further, when the angle becomes abnormally large and a reverse warp occurs, the retainer block may come off from the mounting seat.

As described above, although the use of the retainer block makes it convenient to remove the toilet seat and the toilet lid from the casing, the problem remains that the toilet seat and the toilet lid may come off from the casing depending on the usability.

The problem to be solved in the present invention is that in a toilet seat device in which a toilet seat and a toilet lid are detachably attached to a casing side via a retainer block, even if the toilet seat and the toilet lid are pushed in a direction to open from their normal standing posture, An object of the present invention is to prevent the retainer block from coming off the casing.

[0012]

The present invention SUMMARY OF] is housed the toilet electrical components inside the casing, a toilet seat apparatus mounted for opening and closing the toilet seat and toilet lid in the casing, before Symbol of the toilet seat and toilet lid housed in the respective proximal end and closing unit containing a mechanism to provide a resistance when closing these toilet seat and toilet lid, a retainer block coupled respectively fixed to the casing to the resistance mechanism of the opening and closing unit, wherein Connect the retainer block to the casing
Connecting means for connecting the retainer block to the case when the toilet seat or the toilet lid is at an angle other than a predetermined angle.
And the toilet seat or lid is at a specified angle.
Is characterized in that a lock mechanism for releasing the restraint is provided .

In order to restrain the retainer block on the hinge chamber side, a stopper surface is provided on the back of the retainer block for receiving a lower end portion of the toilet lid when the toilet lid is in the upright posture, and a load from the toilet lid on this stopper surface is applied to the hinge chamber. Can be transmitted in the storage direction of the retainer block.

Further, a lock pin is provided on the retainer block for a toilet lid so as to penetrate in the width direction so as to face the end face of the proximal end of the toilet lid, and the lock pin is directed toward the end face of the proximal end of the toilet lid. Elastically biasing, providing a cam groove in which the lock pin can protrude and retract on the end face of the base end of the toilet lid, and a lock hole in which the other end of the lock pin can be fitted in the hinge chamber. The arrangement may be such that it can be aligned with the lock pin within the range of the rotation angle when rising to the normal rising angle.

[0015]

[Function] When only the toilet lid or the toilet lid and the toilet seat are to be erected,
The retainer block connecting these base ends to the casing side receives an upward acting force during the erecting movement.
At this time, when the toilet seat or the toilet lid exceeds its normal standing angle, if the retainer block is restricted to the casing side, the toilet seat or the toilet lid can be used without detaching from the casing.

Further, if a stopper surface for receiving the base end portion of the toilet lid is provided on the retainer block so that the load when the toilet lid is erected can be decomposed into a component force in the direction of storing the retainer block, The retainer block is retained in the hinge chamber even when the lid is opened beyond its normal upright angle. Therefore, even if the toilet lid and toilet seat are pushed strongly to the back,
These are prevented from coming off the casing.

Further, a cam groove is provided at the base end of the toilet lid, and a lock pin fitted into the cam groove is provided on the retainer block so that the other end of the lock pin can be restrained on the casing side. If the fitting of the lock pin is set within the normal upright angle range of the toilet lid, the retainer block is restrained to the casing side by the lock pin when the normal upright angle is exceeded. Therefore, even when the toilet lid is widely opened, the retainer block is restrained by the casing and does not come off.

At this time, when the toilet lid 4 is reversely warped, in which an external force is applied to push the toilet lid 4 in the direction of the alternate long and short dash line in the figure, the base end of the toilet lid 4 has only the contact surfaces 4e and 4f. Abuts against another member, that is, the retainer blocks 7 and 8. For this reason, as shown in the figure, the toilet lid 4 has the stopper surfaces 7h, 8
When the force pushing the h and F _2, these stop surfaces 7h,
Since 8h is inclined with respect to the horizontal plane, it is decomposed into horizontal and vertical component forces F ₃ and F ₄ . In these component forces F ₃ and F ₄ , the horizontal component F ₃ acts on the rising surface inside the front surface of the mounting groove 2 b of the casing 2, but is received on this surface, so that the horizontal component F ₃ is received in this horizontal direction. not be moved by the component force F _3. Therefore, applying an action force in the direction of dropping the retainer blocks 7 and 8 the hinge chamber 2a by vertical component force F _4.

As described above, when the toilet lid 4 is warped in the reverse direction, the casing 2 itself does not become the pivot of the toilet lid 4 and
By using the stopper surfaces 7h and 8h of the retainer blocks 7 and 8 that connect the toilet lid 4 to the casing 2 as a fulcrum, even when the toilet lid 4 is reversely warped, the retainer blocks 7 and 8 can come out and rattle. Can be prevented.

In the case where the toilet lid 4 is erected and the toilet seat 3 is subsequently raised, it is needless to say that the retainer blocks 7 and 8 can be stably held similarly.

FIG. 14 is an exploded perspective view of an example in which the mechanism between the opening / closing unit 6 on the toilet lid 4 side and the retainer block 8 can be locked.

A fan-shaped cam groove 6f is provided on the surface of the opening / closing unit 6 facing the retainer block 8, and a lock pin 9 which falls into the cam groove 6f and prevents rotation of the opening / closing unit 6 is incorporated in the retainer block 8.

e. The stroke determined by the E-ring 9a is set such that the other end comes out of the lock hole 2e when the tip of the lock pin 9 falls into the cam groove 6f as shown in FIG.

The lock pin and the lock hole are provided with the opening / closing unit 5 for the toilet seat 3 and the retainer block 7.
May be provided as a similar configuration.

When the toilet lid 4 is closed, as shown in FIG. 15A, the cam groove 6f is located below the lock pin 9 at the home position, which is out of phase by 90 degrees. . At this time, as shown in FIG. 16A, since the tip of the lock pin 9 abuts against the end face of the opening / closing unit 6, the spring 9c is pushed and the other end is fitted into the lock hole 2e. I have. Therefore, the retainer block 8 is restrained on the casing 2 side by the lock pin 9 and the lock hole 2e, and cannot be pulled out even if the toilet lid 4 is pulled out upward.

Here, when the toilet seat 4 is raised and its angle becomes about 90 degrees, the cam groove 6f includes the lock pin 9 as shown in FIG. For this reason,
As shown in FIG. 16B, the lock pin 9 enters the cam groove 6f by the urging force of the spring 9c. The movement of the lock pin 9 causes the lock hole 2e to move.
One end of the lock pin 9 comes out of the retainer block 8
The constraint between the and the casing 2 is released. Therefore,
15B, the retainer block 8 can be pulled out of the hinge chamber 2a only when the toilet lid 4 is erected about 90 degrees, and the toilet lid 4 Can be removed from the casing 2.

As described above, as long as the toilet lid 4 is not raised at a certain angle, the retainer block 8 is restrained by the lock pin 9 on the casing 2 side. 3 cannot be withdrawn. When the toilet lid 4 stands up and reverse warp occurs as shown by a dashed line in FIG. 13, the opening / closing unit 6 further rotates clockwise from the state shown in FIG. 9 is pushed out from the cam groove 6f. Therefore, the lock pin 9 returns to the state shown in FIG. 16A and locks the retainer block 8 to the casing 2 side. Therefore, even if reverse warpage occurs, the retainer block 8 does not fall out of the casing 2, so that the toilet lid 4, the opening / closing units 5, 6 and the toilet seat 3 do not fall apart.

When the toilet seat 3 and the toilet lid 4 are to be removed, the toilet lid 4 is held so that the standing angle thereof is about 90 degrees, and the toilet lid 3 can be easily removed from the casing 2 by pulling it up together with the toilet seat 3. Can be.
