Description

[Detailed Description of the Invention] The present invention relates to a toilet seat mounting device for rotatably mounting and supporting a toilet seat on a Western-style toilet bowl.

Conventionally, in this type of toilet seat mounting device, both ends of a hinge shaft that rotatably passes through the toilet seat are inserted between a pair of toilet seat mounts to support the shaft, and a threaded portion formed at the lower end of both toilet seat mounts is attached to the toilet bowl. The toilet seat is attached to the toilet bowl by inserting it into the opened toilet seat attachment hole and screwing a nut onto the tip from below to tighten it.

On the other hand, when cleaning the toilet bowl and toilet seat, it is easier and more reliable if the toilet seat is removed from the toilet bowl.

However, in the above-mentioned conventional type, in order to remove the toilet seat mount from the toilet bowl, the nut must be removed in a very narrow space below the toilet bowl and in an awkward position, and furthermore, special tools are required. For this reason, housewives who clean the toilets were unable to remove the toilet seat.

The purpose of the present invention is to solve the above-mentioned problems and to enable anyone to easily attach and detach the toilet seat.

The basic structure of the present invention is that from the insertion hole that penetrates the toilet seat mount in the vertical direction, it extends from the top surface toward the periphery of a substantially cylindrical elastic body that is non-rotatably attached to the toilet seat mount inside the toilet seat mount hole. A mounting bolt having a tool engagement groove is rotatably inserted through the bolt, and a threaded portion cut into the tip of the mounting bolt is screwed into a nut fixed non-rotatably to the lower part of the elastic body. By rotating the nut with a tool from above the toilet bowl and moving it upward or downward, the elastic body is deformed and brought into contact with and away from the inner peripheral surface or lower edge of the toilet seat mounting hole.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In this embodiment, as shown in Fig. 1, a toilet seat F and a toilet lid G are arranged between a pair of toilet seat fittings A and A, and these toilet seat F and toilet lid G are placed between both toilet seat fittings A and A. They are each rotatably supported by a horizontal hinge shaft H.
