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.

Traditionally, it has been easier to clean household toilets by removing the toilet seat from the toilet bowl.
In addition, since it is possible to clean every nook and cranny, there is a demand for a structure in which the toilet seat can be easily attached and detached.On the other hand, in public toilets, there are concerns about theft and mischief, so it is desirable to have a structure in which the toilet seat cannot be easily attached and detached. is requested.

In order to meet these demands, toilet seat mounting devices for general household use and toilet seat mounting devices for public use must be prepared separately, resulting in high costs.

This invention solves these problems and allows the toilet seat to be easily attached and detached when used on a general household toilet with a single toilet seat mounting device, and the toilet seat can be easily attached and detached when used on a public toilet. The purpose is to make it impossible.

The basic structure of the present invention is to form a head at one end of the hinge shaft, and to continuously drill a through hole through which the shaft of the hinge shaft is inserted and a recessed hole to house the head in both fixture bodies. At the same time, by arranging the opening positions of these through holes and recesses in the left and right directions, and installing both fixture bodies with the left and right swapped, the head of the hinge shaft is exposed outside the fixture body, and the fixture body is exposed. It is placed in a state where it is stored inside.

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 D and a toilet lid E are arranged between a pair of fixture bodies A and A'.
Two hinge shafts B, B with these inserted from the outside
They are each supported by a shaft.

The hinge shaft B includes a cylindrical shaft portion b1 made of an elastic material, for example, a synthetic resin such as polyacetal or polypropylene, and a head portion formed at one end of the shaft portion b1 with a diameter larger than that of the shaft portion b1. b
2 and an elastic portion b3 formed at the other end of the shaft portion b1, and a protrusion b4 is formed at an appropriate position on the outer peripheral surface of the shaft portion b1.

The pair of fixture bodies A and A' each have a through hole a1 in the upper part having an inner diameter slightly larger than the outer diameter of the shaft part b1 of the hinge shaft B, and an inner diameter slightly larger than the outer diameter of the head b2. Furthermore, a recessed hole a2 having the same length as the axial length of the head b2 or slightly longer than that is continuously opened in the horizontal direction.

The opening positions of the through hole a1 and the recessed hole a2 are the opening position in one fitting body A and the opening position in the other fitting body A.
The opening position at A' is arranged in the opposite left and right, and both fitting bodies A and A' each form a threaded part a3 at the bottom, and this threaded part a3 is attached to the rear upper wall c1 of the toilet bowl C in the upper and lower parts. It is fixed by inserting it into the toilet seat mounting hole c2 that is opened in the direction and screwing it in with a nut 4 from below.

A hinge shaft B is attached to the left and right peripheries of the through hole a1.
Locking portions 1, 1 are provided in recesses, respectively, to engage with protrusions b4 formed on the shaft portion b1.

The above-mentioned protrusion b4 is formed by forming the upper surface into a chevron shape in the axial direction of the hinge shaft B, and by penetrating and opening a planar U-shaped notch b5 around the upper surface of the protrusion b4.
4 is constructed so that it can freely appear and disappear in the vertical direction.

Therefore, no matter which direction the hinge shaft B is inserted into the through hole a1 from the left or right of the fixture body A, A', the protrusion b4 engages with the locking portion 1, and the hinge shaft B is normally inserted into the through hole a1.
It never comes out.

Incidentally, the protrusion b4 may be configured to be retractable by a spring or a leaf spring other than the one shown in the drawings.

In addition, on the periphery of the recessed hole a2, there is a mounting body A,
A concave notch 2 is formed so as to be exposed on the side surface of A′,
When the head b2 of the hinge shaft B is housed in the recess a2, the tool 3 is inserted into the recess 2 to pull out the hinge shaft B, as shown in FIG.

At this time, the hinge shaft B can be easily pulled out by forming a locking edge b6 projecting outward on the circumferential surface of the head b2 of the hinge shaft B, or by forming a groove that engages with the tool 3 (not shown). .

The toilet seat D has a pair of mounting pieces d2 and d at its base end.
2 are provided protrudingly, and these mounting pieces d2, d2 have through holes a1 and recesses a2 of the above-mentioned fixture bodies A, A'.
A hinge hole _d1 is drilled coaxially with each other.

Similar to the toilet seat D, the toilet lid E has a mounting piece e2 protruding from its base end with a hinge hole e1, and in this embodiment, the mounting piece e2 is attached to the left and right mounting pieces d2 of the toilet seat D. , d2, and its hinge hole e
1. Insert the elastic part b3 of the hinge shaft B into the inside of the hinge shaft B.

The elastic portion b3 has an outer diameter larger than the inner diameter of the hinge hole e1 of the toilet lid E, and the hinge shaft B
By forming a cut b7 having a cross-shaped cross section in the axial direction, the elastic part b3 is pressed against the inner circumferential surface of the hinge hole e1 when inserted into the hinge hole e1. Now cut b7
Although the shape is cross-shaped in cross section, the shape is not limited.

Further, the elastic portion b3 forms inclined surfaces b8 and b9 at the front and rear in the axial direction, respectively, to facilitate insertion and removal of the hinge shaft B.

Therefore, when such a toilet seat mounting device is used for a general household toilet bowl C, the recesses a2 and a2 of the pair of fixture bodies A and A' are located inward, respectively, as shown in Fig. 1. Then, insert both hinge shafts B, B from the through holes a1, a1 side, respectively. In this state, simply pull out the head b2 of the hinge shaft B that is exposed outside both fixture bodies A and A', respectively, to the outside.
The toilet seat D and toilet lid E can be easily removed.

In addition, when using it for a public toilet C, the above-mentioned two fitting bodies A and A' are swapped left and right, and the concave hole a2,
Attach so that a2 is located outward, and insert both hinge shafts B and B from the recessed holes a2 and a2 sides, respectively. In this state, both hinge shafts B, B cannot be pulled out unless the tool 3 is used.

In the above embodiment, the locking portions 1, 1 that engage with the protrusion b4 of the hinge shaft B are provided on the left and right peripheries of the through hole a1.
However, the invention is not limited to this,
Instead of recessing the locking parts 1, 1, the mounting position of the protrusion b4 may be moved toward the elastic part b3 side and brought into contact with the left and right circumferential surfaces of the through hole a1.

Since the present invention has the above configuration, it has the following advantages.

In a toilet seat mounting device in which a toilet seat is rotatably supported via a hinge shaft on a pair of fixture bodies fixed to a toilet bowl, a head whose diameter is larger than that of the other portion is attached to one end of the hinge shaft. A through hole for inserting the shaft portion of the hinge shaft and a concave hole for housing the head are continuously drilled in both the above-mentioned fixture bodies, and the opening positions of these through holes and concave holes are reversed left and right. Since I placed it in
By swapping the left and right sides of both fixture bodies and installing them, the head of the hinge shaft can be placed in a state where it is exposed outside the fixture body and in a state where it is housed inside the fixture body, making it possible to install it in a general household with a single toilet seat mounting device. When used on a toilet bowl, the toilet seat can be easily attached and detached by pulling out the hinge shaft while the fixture body is fixed to the toilet bowl, making cleaning the toilet bowl and seat very easy, and making it possible to clean every nook and cranny. When used in a public toilet, the toilet seat cannot be easily attached or removed, and there is no need to worry about theft or mischief.

Therefore, there is no need to separately prepare a toilet seat mounting device for general household use and a toilet seat mounting device for public use, as in the past, and costs can be reduced.
