Description

[Detailed explanation of the invention] When using conventional Western-style toilets in the restrooms of hotels and public facilities, there is a sense of hygienic anxiety when lifting the lid by hand, even if the toilet has been disinfected and cleaned. Some people who do not know how to use a toilet bowl may lift only the lid to use it, which is uncomfortable and unsanitary. In order to solve this problem, an arm is fixed to the lid, and the arm is extended to the outside of the lid.
A device was devised in which an engaging piece that enters and exits from the outside between the toilet seat and the toilet bowl is pivotally supported on an extension portion, and the engaging piece is moved in and out from the outside using a handle (Japanese Utility Model Publication No. 7080/1983). However, with this device, it is necessary to use two different operations: raising and lowering the extension and rotating the handle, which is not only cumbersome to operate, but also requires the arm to extend outside the lid and the handle and the handle to be engaged with the extension. Since the joining pieces are pivotally connected, there is a problem that the device is complicated and cannot be simplified. In addition, a device was devised in which a main body is provided on the top mounting plate of the lid, upper and lower arms perpendicular to each other are provided rotatably around a vertical axis, and the lower arm is moved in and out from the outside between the toilet seat and the toilet bowl. (1977)
−141942). However, even with this device, the main body and upper and lower arms protrude outside the lid, making the device complicated, and the upper arm is operated by changing the angle of the upper arm sideways or forward, making it difficult to simplify the operation. In any case, the above-mentioned engaging piece and lower arm that go in and out of the bottom surface of the toilet seat go in and out from the outside of the toilet seat, so the engaging piece and lower arm that come out to the outside after entering the toilet bowl give the user a feeling of uncleanliness. There was a problem.

The purpose of this invention is to obtain a toilet seat opening/closing device that has a simple structure, does not give a feeling of uncleanliness, and is easy to operate.

In order to achieve the above object, the present invention is such that the locking arm 3 is pivotably supported 3' on the arm fulcrum board 8 provided on the back surface of the lid 1, and a handle 4 is provided at the tip of the arm 3. A claw 5 for engaging and disengaging the toilet seat is provided on the lower surface of the arm 3 in the middle thereof, and the length of the arm 3 extends from the center of curvature of the arcuate edge a extending from the tip of the lid 1 toward the side. The toilet seat opening/closing device is formed so that the handle 4 is provided on the outside of the arcuate edge a.

Therefore, by grasping the handle 4 and rotating it in the positive direction about the shaft support 3', the tip 5' of the engaging claw 5 is moved to the toilet seat 6 as shown by the solid line in FIG.
The lid 1 and the toilet seat 6 can be rotated downward and the claw 5 can engage the lid 1 and the toilet seat 6. In this state, the lid 1 and the toilet seat 6 can be opened by grasping the handle 4 and lifting it upward. can. At that time, the indicator 13 and the "small" on the lid side
It is marked by a mark 9'. Further, the tip portion 5' can be rotated in the opposite direction to the notch 7' of the toilet seat 6 to separate the toilet seat 6 and the lid 1. In this state, the handle 4 is grasped and the lid 1 is removed. can only be opened. At this time, the indicator 13 and the "large" mark 9 on the lid side match.

In addition, in the above toilet seat opening/closing device, the outer edge 2 of the back surface of the lid 1
A notch 1' for rotation of the arm 3 is formed in the inner edge 7 of the toilet seat 6, and a notch 7' for detachment of the engagement claw 5 is formed in the inner edge 7 of the toilet seat 6.
The arm 3 projects outward from the notch 1' of the lid 1, and a handle 4 containing a synthetic resin indicator 13 is provided at the tip of the arm 3.
Small markings can be added. The above-mentioned engagement claw 5
The distal end 5' of a downward small vertical arm attached to the arm 3 rotates to the underside of the toilet seat 6 through a notch 7' in the toilet seat 6. The cutouts 1', 7' are not necessarily required as shown in FIG. Further, the height of the claw 5 may be set to an appropriate height as required.

The present invention is constructed as described above, and the lid 1 and the toilet seat 6 can be opened and closed at the same time accurately by rotating the handle 4 in the forward and reverse directions and manually raising and lowering the handle 4 according to the use. However, since the lid 1 alone can be opened and closed easily and quickly, and there is no need to hold the toilet seat 6, the toilet seat can be opened and closed in an extremely hygienic manner, and there is also the practical benefit of being able to easily attach it to an existing toilet seat. Further, in this case, when the lid 1 is closed (the state shown in FIG. 1), only the handle 4 can be exposed outside the arcuate edge a of the lid 1, and the handle 4 can be slid very easily along the arcuate edge a. It is possible to obtain a toilet seat opening/closing device which is not only easy to operate, but also extremely simple and clean, and which does not give a feeling of uncleanliness.
