Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fall prevention device for keeping a toilet seat, which is attached to a Western-style toilet bowl so as to be openable and closable, in an upright position.

[Conventional technology]

Conventionally, a toilet seat for a person to sit on is attached to a Western-style toilet bowl so that it can be opened and closed, and when used for men's toilets, the seat is rotated to the rear of the toilet body.

However, recently, toilets have been developed that have a flush water tank integrated into the rear of the toilet bowl or are equipped with sanitary cleaning devices for private parts, and the mounting structure of the toilet seat also needs to be changed accordingly. It is occurring.

The most common mounting structure for such a toilet seat is one in which the toilet seat is rotatably attached to the toilet body or sanitary washing device using a hinge or other means, so that the rotation angle of the toilet seat is adjusted when the toilet seat is erected. The placement relationship with other equipment is determined so that the angle is 90 degrees or more so that it does not fall over during use.

[Problem that the invention attempts to solve]

However, when a flush water tank and a sanitary cleaning device are arranged in a toilet main body having a limited dimensional capacity, the angle of rotation of the toilet seat toward the rear is limited. Therefore, the toilet seat cannot be maintained in its upright position and must be held by hand during use.

In addition, in recent years, toilet seats are often covered with covers to keep them warm, and toilet lids are also often provided with covers for decorative purposes, making it difficult to keep the toilet seat upright due to the thickness of the cover. is also occurring.

The purpose of this invention is that even when various accessories are installed on the toilet bowl body or a cover is provided on the toilet seat itself,
To ensure that a toilet seat can be kept in an upright position.

[Means for solving problems]

The toilet seat tipping prevention device of the present invention has a protrusion formed around the pivoting part of the toilet seat to the toilet bowl body, and an elastic engagement piece is arranged at a portion of the toilet bowl body that corresponds to the protrusion. Legs are provided at both ends of the side of the joint piece facing the toilet main body, and a protruding piece that can engage with the protrusion is provided on the other side, and the pair of legs are separated in the direction in which the protrusion of the toilet seat rotates. The toilet bowl is characterized in that the toilet bowl is fitted into a groove provided in the toilet bowl main body as a posture, and a space is provided between the elastic engagement piece on the side where the legs are provided and the surface of the toilet bowl main body.

〔Example〕

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

Fig. 1 is a perspective view of a Western-style flush toilet equipped with a device for preventing the toilet seat from tipping over according to the present invention, in which 1 is the toilet body, a flush water tank 2 is located at the rear of the toilet bowl, and a flush water tank 2 is installed at the rear of the toilet bowl, which sprays flush water to the private parts and also supplies warm air. A sanitary cleaning device 3 containing various devices is installed.

Reference numeral 5 denotes a toilet seat which is pivotally attached to the casing 4 of the sanitary washing device 3 so that it can be opened and closed, and a toilet lid 6 is similarly attached to the same pivot so that it can be opened and closed.

The toilet seat 5 is pivotally connected at both rear ends to hinge pins 7 of the casing 4, and FIG. 2 shows a cross-sectional view of a main part thereof.

In FIG. 2, the hinge pin 7 is arranged in the width direction of the casing 4, and pivotally supports both the toilet seat 5 and the toilet lid 6.

At both rear ends of the toilet seat 5, an arm 9 having a hole 8 through which the hinge pin 7 is inserted is formed in an arc shape around the hinge pin 7, and a projection 10 projecting outward is provided on a part of the circumferential surface of the arm 9.

Further, reference numeral 11 denotes an elastic engagement piece integrally fixed to the front inclined surface of the casing 4, which is made of synthetic resin such as polypropylene, and has an upwardly protruding portion on the top surface as shown in the cross section of FIG. A protruding piece 12 is formed. The projecting piece 12 has a guide surface 13 with a gentle slope on one side, and an engagement surface 14 with a substantially right angle slope on the other side. In addition, the elastic engagement piece 11
Legs 11a for fixing to the casing 4 are formed at both ends with the guide surface 13 and the engagement surface 14 interposed therebetween. On the other hand, these legs 11 are attached to the casing 4.
A groove 4a is cut into which the hole 4a is fitted.
As is clear from FIG. 2, a slight gap A is provided between the front surface of the casing 4 and the back surface of the elastic engagement piece 11. In this way, by providing the legs 11a at both ends of the elastic engagement piece 11 and separating them from the surface of the casing 4,
The elastic engagement piece 11 can be structured to be easily elastically deformed.

Here, the protrusion 10 on the toilet seat 5 side and the elastic engagement piece 11
The relative arrangement of the side protrusions 12 is such that when the toilet seat 5 is in the closed position, the protrusions 10 are located on the upper rear side from the inclined surface of the casing 4, as shown in FIG.
In this state, the angle α formed by the protrusion 10 and the protruding piece 12 is approximately the rotation angle of the toilet seat 5, and in order to reliably hold the toilet seat 5 in the upright position, it is preferable that this angle α is 90° or more. .

In the above configuration, when the toilet seat 5 and the toilet lid 6 are rotated upward, the arm 9 of the toilet seat 5 has a protrusion 1 on the circumference.
0 moves from the guide surface 13 of the elastic engagement piece 11 toward the apex of the protruding piece 12. In this case, the elastic engagement piece 11
Due to the elastic deformation of the protrusion 10, the protrusion 12 easily
It can be positioned on the engaging surface 14 side by climbing over. Since there is a gap A between the elastic engagement piece 11 and the surface of the casing 4, when the protrusion 10 pushes down the protrusion 12, it easily elastically deforms and bends downward, so that the toilet seat can be moved to a standing position.

As described above, the toilet seat 5 has a protrusion 1 at its lower end.
0 engages with the protruding piece 12 of the elastic engaging piece 11 and is maintained in an upright state as shown in FIG. 4, thereby preventing it from falling down.

Furthermore, when closing the toilet seat 5, by pushing the toilet seat 5 downward, the protrusion 10 can be easily closed by moving over the protrusion piece 12 to the guide surface 13 side due to the elastic deformation of the elastic engagement piece 11 as described above. .

In the above embodiment, the elastic engagement piece 11 is provided on the casing 4 of the sanitary washing device 3, but it may also be provided on the toilet main body 1.

[Effect of idea]

This invention allows the toilet seat to be held in the upright position by the elastic engagement piece even when various devices are installed on the toilet bowl body or a cover is attached to the toilet seat and toilet lid. By appropriately selecting the relative formation positions of the protrusions, it is possible to arbitrarily set the upright angle of the toilet seat. In addition, since the elasticity of the elastic engagement piece itself is utilized, there is no need to provide other biasing members, and it can be installed without taking up space between the base end of a narrow toilet seat and the toilet bowl body. There is no need to change the design of the toilet seat or the toilet bowl itself.
