Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a mounting structure for a toilet seat or a toilet lid provided in a seat-type flush toilet bowl.

[Conventional technology]

A seat-type flush toilet is generally provided with only a toilet seat on which a person sits or a toilet lid provided on the toilet seat. These toilet seats and lids are provided with a mounting seat at the base end and are pivotally attached to the toilet body by a hinge structure, or are connected to a casing of a sanitary washing device having a local washing function.

FIG. 8 is a perspective view showing an example in which the sanitary washing device A is installed on the toilet body B. The sanitary washing device A is a washing water tank C.
The nozzle device and equipment for supplying washing water are housed inside the casing 1 on the front side. And
A toilet seat 2 and a toilet lid 3 are attached to the casing 1 so as to be openable and closable by a hinge structure.

The toilet seat 2 and the toilet lid 3 are pivotally attached to the casing 1 so as to be rotatable independently of each other by a common hinge shaft.
FIG. 9 shows the main part of the pivot structure. As shown in the figure, a pair of mounting seats 20 and 21 are provided at both ends of the base ends of the toilet seat 2 and the toilet lid 3, respectively, and mounting holes 22 and 23 are formed in these. Then, the hinge shaft 24 is inserted by aligning the cores of the mounting holes 22 and 23, and the tip end of the hinge shaft 24 is fitted into the pivot hole 25 of the casing 1, so that the toilet seat 2 and the toilet lid 3 are pivotally mounted so as to be openable and closable. . Further, the tip end portion of the hinge shaft 24 has a spherical shape with a slit 24a formed therein, and can be fitted into the pivot hole 25 by utilizing the elastic deformation of the slit 24a, and unless a tool or the like is used, the casing. It is retained without dropping from 1.

[Problems to be solved by the device]

To remove the hinge shaft 24 from the casing 1, use the slit
Since 24a elastically deforms so as to pass through the pivot hole 25, a considerably large force is required, which requires a tool as described above. However, as shown in FIG. 9, when the flange 24b of the hinge shaft 24 hits the side surface of the mounting seat 20 of the toilet seat 2 tightly, a screwdriver or the like is used to remove these flanges 24b.
It is quite difficult to insert it into the contact surface between b and the mounting seat 20. In particular, in the structure in which the recess 20a is provided in the mounting seat 20 and the flange 24b is embedded in the recess 20a for improving the appearance, it is difficult to hang a tool.

As described above, if the tool cannot be easily hooked when removing the toilet seat 2 or the toilet lid 3, maintenance and inspection will be troublesome. If the hinge shaft 24 is made of synthetic resin or the like, the flange 24b will be rubbed with a tool many times, so that the flange 24b will be torn or gouged. For this reason, the hinge axis 2
4 may have to be replaced, and the toilet seat 2 and toilet lid 3 may be damaged.

Therefore, an object of the present invention is to easily remove the hinge shaft without damaging the hinge shaft, the toilet seat, or the toilet lid.

[Means for Solving the Problems]

In order to achieve the above object, the toilet seat or toilet lid mounting structure of the present invention is provided with a mounting seat at the base end portion of the toilet seat or toilet lid, and the toilet seat or toilet lid is attached by a hinge shaft that penetrates the mounting seat. It is a mounting structure that can be opened and closed freely on the toilet body side,
In the mounting seat, a holding seat for accommodating the flange formed at the base end of the hinge shaft is formed in a recess in the insertion direction of the hinge shaft,
The holding seat includes a holding wall having a mounting hole through which the hinge shaft penetrates and a peripheral wall that covers a part of the peripheral surface of the flange, and the flange abuts a gap between the flange and the holding wall. A spacer block for holding is provided at a position along at least a part of the peripheral wall, and at a position on the inner peripheral surface of the peripheral wall that is away from the surface where the spacer block abuts the flange, on a part of the outer periphery of the flange. It is characterized in that a constraint block having a conforming shape is provided, the flange of the hinge shaft is abutted against the spacer block, and at least a part thereof can be engaged with and disengaged from the constraint block.

〔Example〕

Hereinafter, the features of the present invention will be specifically described with reference to the embodiments shown in the drawings.

FIG. 1 is a cross-sectional view showing an essential part of the present invention.

The toilet seat 2 and the toilet lid 3 are pivotally attached to the casing 1 of the sanitary washing device A by a hinge shaft as described in FIG. FIG. 6 is a plan view showing the casing 1, the toilet seat 2 and the toilet lid 3. The casing 1 of the sanitary washing device A is provided with the operation panel 4 at the left end, and the seats 2a and 3a of the toilet seat 2 and the toilet lid 3 are attached. A bulging portion 5 is formed so as to protrude toward the front side so as to sandwich the bulge. Then, as shown in FIG. 7, the left and right facing surfaces 5a on which the bulging portion 5 sandwiches the mounting seats 2a and 3a are pivoted as shown in FIG.
5b is formed. As shown in FIG. 1, the pivot hole 5b is formed as a concave portion which enters the inside of the casing 1 from the facing surface 5a, and the casing 1 is provided with a toilet seat 2 and a toilet lid 3 for attachment unlike the conventional example. No holes have been drilled.

As shown in FIG. 2, a hinge shaft 6 which pivotally mounts the toilet seat 2 and the toilet lid 3 on one axis has a flange 6a formed at one end and a thin rod 6b protruding from this portion. Also,
On the peripheral surface of the flange 6a, a projection 6c is formed that is tapered so that the rod 6b side has a small diameter.

The toilet seat 2 and the toilet lid 3 are, as shown in FIGS. 1 and 2,
The seat 2a of the toilet seat 2 is located outside (the side that contacts the facing surface 5a of the casing 1), and the seat 3a of the toilet lid 3 is located inside, and is connected to the casing 1 by the hinge shaft 6. Note that FIGS. 1 and 2 show the right-hand pivoting portions of the toilet seat 2 and the toilet lid 3 shown in the plan view of FIG. 6, and the pivoting structures of the left-hand mounting seats 2a and 3a are also completely absent. It is the same.

3 is a perspective view of the mounting seat 3a of the toilet lid 3 viewed from the bottom side, and FIG. 4 is a front view of the mounting seat 3a viewed from the inside.

On one surface of the mounting seat 3a, a peripheral wall having an inner diameter enough to fit the protrusion 6c formed on the flange 6a of the hinge shaft 6 tightly.
The holding seat 7 is formed by 7a. This holding seat 7
Has a cross-sectional shape in which the lower surface side of the mounting seat 3a is open, and a holding wall 8 is formed on the outer side surface so that the vertical cross section is substantially circular, and a mounting hole 8a into which the hinge shaft 6 is inserted is formed.
Has been installed. Further, the hinge shaft 6 is provided inside the holding wall 8.
A spacer block 9 is formed on which the flange 6a abuts, and a pair of restraining blocks 10 for holding the flange 6a together with the spacer block 9 are provided on the inner periphery of the peripheral wall 7a of the holding seat 7.

As shown in FIG. 4, the spacer block 9 is formed inside the peripheral wall 7a and at the lower end portion when the toilet lid 3 is turned upside down. It has a substantially semi-circular shape when viewed in the inserting / removing direction of 6. The restraint block 10 is the inner peripheral surface of the peripheral wall 7a,
As shown in FIG. 2, a space L is formed between the spacer block 9 and the spacer block 9.
It is formed in an open position and has a shape capable of restraining the periphery of the flange 6a of the hinge shaft 6 as shown in FIG. The size of this interval L is set to be approximately equal to the axial thickness of the protrusion 6c of the hinge shaft 6, and the inner diameter of the circle drawn by the inner circumference of the restraint block 10 is the outer diameter of the flange 6a of the hinge shaft 6. Form to match.

Here, when assembling the toilet seat 2 and the toilet lid 3 to the casing 1, first, the mounting seats 2a and 3a of the toilet seat 2 and the toilet lid 3 are overlapped as shown in FIG. 2, and the respective mounting holes 2b and 8a are attached. Temporarily align the cores. Then, the mounting seats 2a and 3a are set so as to be fitted between the left and right bulged portions 5 of the casing 1, and the hinge shaft 6 is inserted into the mounting holes 2b and 8a. The hinge shaft 6 is the first
As shown in the figure, the tip of the rod 6b enters the pivot hole 5b,
The protrusion 6c of the flange 6a is fitted between the spacer block 9 and the restraining block 10.

In the above assembly, if the distance between the outer end surfaces of the toilet seat 2 is set to be substantially equal to or slightly shorter than the distance between the facing surfaces 5a of the bulging portion 5, the hinge shaft 6 will be integrated with the casing 1. The toilet seat 2 and the toilet lid 3 are held without being displaced to the left and right. Further, if the casing 1 and the hinge shaft 6 are made of synthetic resin, respectively, when the rod 6b of the hinge shaft 6 is fitted into the pivot hole 5b, they can be fixed by utilizing the elastic deformation of both. That is, if the rod 6b is inserted into the pivot hole 5b with a strong force, the rod 6b can be firmly fixed by elastic deformation of the pivot hole 5b. Therefore, when the toilet seat 2 or the toilet lid 3 is rotated, the hinge shaft 6 does not rotate together, and the toilet seat 2 and the toilet lid 3 can be independently rotated.

In the above structure, since the hinge shaft 6 has the taper ridge 6c provided on the flange 6a thereof, the ridge 6c is inserted into the holding seat 7 so as to ride over the restraining block 10. Then, as shown in FIG. 1 and FIG. 5, the protrusion 6c is fitted between the spacer block 9 and the restraining block 10, the movement in the axial direction is restricted, and the toilet seat 2 and the toilet lid 3 are separated from each other by the casing 1. Be pivoted to. In addition, the pivotal attachment of the respective mounting seats 2a and 3a of the toilet seat 2 and the toilet lid 3 located on the left side in FIG. 6 is the same procedure.

Here, when the hinge shaft 6 is attached, the flange 6a on the side provided with the protrusion 6c does not abut the holding wall 8 of the holding seat 7, and a gap A is formed as shown in FIG. This is because the spacer block 9 is located between the holding wall 8 and
This gap A can be used as a tool hook. That is, when the toilet seat 2 and the toilet lid 3 are removed from the casing 1 for maintenance and inspection, both the toilet seat 2 and the toilet lid 3 are opened, and the open surface of the holding seat 7 (the lower end side of the mounting seat 3a) is opened. Insert a tool such as a screwdriver into the gap A facing upward and insert the hinge shaft 6
Can be removed. By using such a gap A, the tool can be easily hung on the flange 6a of the hinge shaft 6, and the extraction work becomes easy. Further, since it is not necessary to force the tool to be pushed, neither the flange 6a portion is torn nor the mounting seat 3a of the toilet lid 3 is damaged.

In the above embodiment, the hinge shaft 6 is held by using the mounting seat 3a of the toilet lid 3. However, in the case of only the toilet seat 2, the mounting seat 2a has a similar configuration, It is possible to easily remove the hinge shaft 6 and prevent damage.
Further, as shown in the conventional example of FIG. 9, the toilet seat 2 and the toilet lid 3
The same is true when and are connected to the casing 1 by the hinge shaft 6. Further, instead of connecting the toilet seat 2 and the toilet lid 3 to the casing 1 of the sanitary washing device A, a structure may be used in which a pedestal is provided on the toilet body B to connect them.
