BACKGROUND OF THE INVENTION
The present invention relates to a toilet seat device in a seat-type toilet, and more particularly to a toilet seat attaching / detaching mechanism.
[0002]
[Prior art]
The toilet seat is attached to the toilet side block so as to be rotatable. However, when it is possible to remove the toilet seat, the toilet seat can be removed by rotating the toilet seat. The fitting portion with the shaft is fitted using spring elasticity, and the toilet seat can be detached from the rotating shaft by applying a required force.
[0003]
[Problems to be solved by the invention]
However, in the case of removing the rotating shaft, it takes time to attach and detach the rotating shaft, and because the rotating shaft is easily contaminated, it is not recommended to touch the rotating shaft. There was a problem that it was difficult to attach and detach because it was small.
[0004]
Although it is not difficult to attach and detach with spring elasticity, there is a possibility that the toilet seat may be pulled inadvertently.
[0005]
The present invention has been made in view of these points, and an object of the present invention is to provide a toilet seat device that can be easily attached and detached only when necessary.
[0006]
[Means for Solving the Problems]
Thus, the present invention includes a rotating shaft portion provided in the toilet side block and a fitting portion that is fitted to the rotating shaft portion, and is rotatable about the rotating shaft portion and the shaft of the rotating shaft portion. The toilet seat is also movable in the direction and a restricting member that restricts the axial movement of the fitting portion of the toilet seat, and the fitting portion is attached to and detached from the rotating shaft portion at one end side of the axial movement. The restriction member is characterized in that it restricts the movement of the fitting portion toward the one end side.
[0007]
When the restriction on the axial movement of the fitting portion of the toilet seat by the restricting member is released and the toilet seat is moved in the axial direction of the rotating shaft portion, the toilet seat can be removed from the rotating shaft portion due to the presence of the detachable opening.
[0008]
A toilet lid can be suitably used as the restriction member.

On the other hand, the toilet seat 2 has a connecting portion 20 whose rear end portion is rotatably connected to the toilet block 1 and includes fitting portions 21 and 22 at both ends of the connecting portion 20, respectively. The fitting part 21 is connected to the right rotating shaft 11, and as shown in FIGS. 1 and 6, a detachable opening that opens on the side of the connecting part 20 with a width smaller than the inner diameter of the fitting part 21. 23 and a large opening 24 that opens at one end of the opening 23 for attachment / detachment with a width equal to the inner diameter of the fitting portion 21.
[0011]
The fitting portion 21 is fitted to the right rotation shaft 11 by inserting the large diameter portion 11a of the right rotation shaft 11 into the fitting portion 21 through the large opening 24 and shifting the toilet seat 2 in the axial direction so that the large diameter portion 11a is inserted. This is done by positioning the detachable opening 23 at a portion that opens to the side surface. Although the opening width of the detachable opening 23 is larger than that of the right rotation shaft 11, it is smaller than the diameter of the large diameter portion 11 a, so that the right rotation shaft 11 does not come out of the fitting portion 21. . When the toilet seat 2 is removed, the toilet seat 2 is moved in the axial direction so that the large-diameter portion 11a is positioned at the large opening 24, and the toilet seat 2 is moved in a direction orthogonal to the axial direction to remove the large opening 24 This is done by removing the right rotation shaft 11 from the fitting portion 21 through the opening 23.
[0012]
The other fitting portion 22 also includes an attachment / detachment opening 25 that opens on the side surface side of the connecting portion 20 with a width smaller than the inner diameter of the fitting portion 22, and a large opening 26 is provided in the middle of the attachment / detachment opening 25. The inner diameter of the fitting portion 22 and the opening width of the large opening 24 are the same.
[0013]
The fitting portion 22 is fitted to the left rotating shaft 13 and the left fixed shaft 14 by inserting the large-diameter portion 14a of the left fixed shaft 14 into the fitting portion 22 through the large opening 26 and the narrow neck portion through the detachable opening 25. 24b is put in the fitting part 22, the toilet seat 2 is shifted in the axial direction, and the large-diameter part 14a is positioned at a part where the opening 25 for attachment / detachment is opened on the side surface. Although the opening width of the opening 25 for attachment / detachment is larger than the width of the narrow neck portion 14b, it is smaller than the diameter of the large diameter portion 14a. Absent. The left rotation shaft 13 is rotated together with the toilet seat 2 by positioning the square cross section at the tip of the left rotation shaft 13 in the engagement section 27 of the square cross section at the back end of the fitting portion 22. When removing the toilet seat 2, the toilet seat 2 is moved in the axial direction so that the large-diameter portion 14a is positioned at the large opening 26, and the toilet seat 2 is moved in a direction perpendicular to the axial direction to remove the large opening 26 and This is performed by removing the left fixed shaft 14 (and the left rotating shaft 13) from the fitting portion 22 through the opening 25.
[0014]
Here, the toilet lid 3 has click engagement portions 30, 30 on both sides of the rear end portion thereof as shown in FIG. 7, and these click engagement portions 30 are fixed to the outer periphery and the left fixed portion of the right fixed shaft 12. The click engagement portions 30 are supported by the outer periphery of the shaft 14 so as to be rotatable. The click engagement portions 30 are provided at both end surfaces of the connecting portion 20 in the toilet seat 2 and the rotation shafts 11 and 13 in the toilet side block 1. For this reason, if the toilet lid 3 is also attached to the toilet block 1, the toilet seat 2 cannot be moved in the axial direction. It becomes a state. That is, the toilet seat 2 cannot be moved to a position where it can be removed from the left fixed shaft 14 or the right rotation shaft 11.
[0015]
To remove the toilet seat 2, first, the toilet lid 3 is removed from the fixed shafts 12 and 14 by using the elasticity of the click engaging portion 30, thereby allowing the toilet seat 2 to move in the axial direction, and then the toilet seat 2 to be moved in the axial direction. To the detachable position, and then the toilet seat 2 is extracted in a direction where the minimum width portion of the narrow neck portion 14b of the left rotation shaft 14 coincides with the detachable opening 25.
