Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement in a bearing for pivotally supporting the pivot end of a toilet seat mounted on a toilet bowl.

[Prior Art and Problems] Conventionally, a bearing 1 for a toilet seat pivot has a bearing hole 3 formed in a main body 2, as shown in FIG. The bearing 1 is inserted into the mounting hole 5b of the toilet main body 5 after the bolt 4 hanging down from the lower surface of the main body 2 is inserted into the mounting hole 5b of the toilet main body 5, as shown in FIG.
It is attached to the upper surface 5a of the toilet main body 5 by screwing a nut 7 onto the toilet bowl body 5. However, conventional bearings 1
had the following shortcomings:

A: When the shaft end 8a of the pivot 8 of the toilet seat 6 is pivoted to the bearings 1, 1 attached to the toilet main body 5, the height H from the toilet top surface 5a to the shaft end 8a is uniquely determined. However, since the toilet seat 6 and/or the toilet bowl main body 5 have dimensional tolerances in manufacturing, all of the rubber feet 6a of the toilet seat 6 in the seated rotational state may not come into contact with the top surface 5a of the toilet bowl.
If there is a rubber foot 6a that does not come into contact with the top surface 5a of the toilet, it will not look good, and furthermore, when sitting on the toilet, excessive force will be applied to the toilet seat 6 and the bearings 1, 1, which may damage them. be.

B○ The toilet seat 6 has many different designs, and the height dimension H from the top surface 5a of the toilet to the shaft end 8a of the pivot 8.
are different for each. Therefore, it is necessary to prepare in advance many types of bearings 1 corresponding to the toilet seat 6 of each design, which results in the trouble of replacing the bearings due to incorrect selection of the bearing 1, and requires a lot of effort to manage the inventory of many types. There was a drawback.

[Object of the invention] The object of the invention is to provide a bearing for a toilet seat pivot to solve the above-mentioned drawbacks.

[Structure of the invention] The gist of the invention is that, in a toilet seat pivot bearing for pivotally supporting the pivot end of a toilet seat, the bearing is rotatably inserted into a fixed housing and an insertion hole drilled in the fixed housing. The bush is provided with a bearing hole recessed on the inner surface side in a state substantially parallel to and eccentric to the rotation axis of the bush, and a bearing hole facing the outside of the fixed housing. and a recessed portion for engaging the rotation adjustment tool is formed on the side surface thereof.

[Description of Examples] Hereinafter, a bearing for a toilet seat pivot according to the present invention will be described based on an example shown in the drawings.

1 and 2 show a first embodiment. The bearing 10 is made of synthetic resin and/or metal, and includes a fixed housing 11 and a bush 12 inserted into an insertion hole 11a formed in the fixed housing 11 in a rotationally adjustable tight fit state. There is. The bush 12 has a bearing hole 13 formed on an inner surface 12a, and the axis A of the bearing hole 13 is approximately parallel to the rotation axis B of the bush 12 and eccentric E. Further, on the outer surface 12b of the bush 12, there is a recess 16 in the shape of a minus groove or a plus groove (see FIG. 4) for engaging the tip of a rotation adjusting tool 15 such as a screwdriver in the fixed housing. It is recessed so as to face the outside of 11. A bolt 4 for mounting and fixing is suspended from the lower surface of the fixed housing 11.

3 and 4 show a bearing 20 of the second embodiment.
This shows that. The difference from the first embodiment is that a notch 22c is formed in the bush 22, and the bush 22 is inserted into the insertion hole 21a of the fixed housing 21.
The bushing 22 is inserted into the fixed housing 21 with a strong interference fit, and moved in the thrust direction by being held between the step 21b formed in the insertion hole 21a of the fixed housing 21 and the ring 24 fitted in the groove 21c. This is something I tried not to do.

[Function] Next, the function of the toilet seat pivot bearing according to the present invention will be explained based on the first embodiment shown in FIGS. 1 and 2. The left and right bearings 10, 10 are mounted on the top surface 5a of the toilet bowl by screwing the nut 7 onto the bolt 4 inserted into the mounting hole 5b of the toilet main body 5, and inserting the shaft end 8a of the toilet seat pivot 8 into each bearing hole 13. Fixed. Next, the bearings 10, 10 are connected to each bush 1.
By operating a rotation adjustment tool 15 such as a screwdriver that is engaged from the outside of the fixed housing 11 with respect to the recess 16 formed in the toilet bowl 2, the bush 12 is forcibly rotated, and the toilet seat pivot 8 is rotated from the top surface 5a of the toilet bowl. The height H up to each shaft end 8a is adjusted so that all of the rubber feet 6a (see FIG. 5) of the toilet seat 6 come into contact with or come closest to the top surface 5a of the toilet bowl.

[Effects of the Invention] As detailed above, the toilet seat pivot bearing according to the present invention has the following practical effects.

The height of the bearing hole can be adjusted simply by forcibly rotating the button, making it possible to bring all of the pivoted rubber feet of the toilet seat into contact with or closest to the top of the toilet. The toilet seat can be placed in a good-looking condition without wobbling, and the pressure applied to the toilet seat is distributed to all the rubber feet when the toilet seat is seated.
Accidents of damage to the toilet seat and bearing can be avoided.

The height of the bearing hole can be adjusted simply by forcibly rotating the bushing, making it possible to accommodate toilet seats of many different designs with different mounting heights of the pivot. There is no need to prepare in advance, and it is possible to avoid the trouble of replacing the shaft and the trouble of inventory management, which conventionally occur due to wrong selection.

The forcible rotational adjustment of the bushing is achieved by simply operating a rotational adjustment tool such as a screwdriver that is locked from the outside of the fixed housing into a recess formed on the outer surface of the bushing, and the pivot end is pivoted. It can be done very easily without any skill required.
