Abstract

PURPOSE:To make it possible to freely change the bore diameter of a seat in accordance with a user such as an adult, a child or the like by coupling the front end parts of seat plates with each other through the intermediary of a changeable joint, and by changing the distance between the rear end parts of the pair of the seat plates with the use of a drive means. CONSTITUTION:In a Western style toilet stool, a pair of right and left C-like shape seat plates 3 forming an annular seat are vertically swingably attached to the rear end part of the top surface of a cylindrical toilet stool body 1 through the intermediary of a crosswise support shaft 2. The rear end parts 4 of the pair of seat plates 3 are laterally slidable on the support shaft 2 by means of bearings 5, 5', and the front end parts 6 thereof are coupled together by means of a changeable joint 7 made of a resilient material so that the distance (I) between the rear end parts of the seat plates may be changed by manipulating a lever 8 attached to one of the rear end parts of the seat plates. When a child uses this toilet stool, the lever 8 is manipulated so as to displace the seat plates in opposite directions so that the space between the seat plates or the bore diameter is decreased, and accordingly, the child can safely use it. When an adult uses this stool, the lever is manipulated to be returned.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a Western-style toilet bowl whose toilet seat diameter can be changed for use by adults or children.

[Conventional technology]

In the conventional Western-style toilet bowl, as shown in FIG.
2, and a disc-shaped lid plate 54 that closes the opening of the toilet seat is attached so as to be swingable in the vertical direction via a support shaft 52. The annular toilet seat 53 on which the user sits is formed to a standard size for adults.

[Problems to be Solved by the Invention] However, in this Western-style toilet, when a child uses the toilet, the child's butt may fall into the toilet body because the diameter of the toilet seat is the size for an adult. There was a problem that it was difficult to use if the size was constant.

This invention was made in view of the problems of conventional products, and its purpose is to provide a Western-style toilet bowl in which the diameter of the toilet seat can be freely changed to accommodate adults and children. This is what we are trying to provide.

[Means for Solving the Problem] In order to achieve the above object, the Western-style toilet according to the present invention has a pair of C-shaped seat plates, which serve as a toilet seat, mounted on the rear end of the upper surface of the cylindrical toilet main body via a support shaft. In addition to being movable and movable along the support shaft, the front end of each seat plate is connected by a direction changing joint, and the distance between the rear ends of a pair of seat plates is changed by a drive means installed at key points. It is possible.

[Effect]

In a Western-style toilet bowl configured in this way, the distance between the rear ends of the toilet seat, which consists of a pair of left and right C-shaped seat plates, is changed by operating the drive means, and the diameter of the toilet seat is changed for adults and children. can.

〔Example〕

FIG. 1 shows a first embodiment of the present invention, and this Western-style toilet bowl has a pair of left and right C-shaped seats that form an annular toilet seat via a horizontal support shaft 2 at the rear end of the upper surface of a cylindrical toilet body 1. A plate 3 is attached to be swingable in the vertical direction, and each rear end 4 of the pair of seat plates 3 is slidable laterally on the support shaft 2 via a bearing 5.5', and each seat plate The front end 6 is connected by a direction changing joint 7 made of an elastic material, and a lever 8 is attached to the end of one seat plate.
The distance 2 between the trailing ends of the rain can be changed by operating the .

The support shaft 2 is supported by the toilet main body via arms 9 at both ends,
A cover plate 10 that can be flipped over the toilet seat is attached to the center of the toilet seat via a bearing 1) so as to be able to swing vertically. The support shaft 2 is equipped with 2 to prevent the extra sliding movement of the bearing 5.5'.
A pair of collar-shaped stops 12 are fixed.

The bearings 5.5' have an inner diameter larger than the outer diameter of the support shaft 2, and since one bearing 5' is swingable in the left and right direction via the pin 13, both seat plates connect the direction changing joint 7 at the other end. Even when bent at the center, both bearings can smoothly slide left and right on the support shaft.

The lever 8 is attached to a fulcrum 15 of a base 14 fixed to the end of the seat plate, and a horizontal bar 16 connected to the other seat vi3 is attached to the intermediate portion of the lever.

One seat plate 3 is provided with a horizontal hole 17 through which a horizontal bar 16 passes. The base is also provided with stoppers 18 that lock the lever at two locations.

The direction changing joint 7 is a part that connects a pair of left and right C-shaped seat plates to form an annular toilet seat, and also serves as a bending point that allows the diameter of the toilet seat to be changed. Joints, pin joints, hinge joints, etc. are used.

When a child uses the Western-style toilet bowl of this embodiment, by holding the lever 8 and moving it in the opposite direction, the distance between the rear ends 4 of the pair of seat plates 3, that is, the diameter becomes narrower (see Figure 1). (See dashed line) Children can use the toilet safely and comfortably, and the next time an adult uses the toilet, they can return it to the original position by operating the lever.

2 and 3 show two other embodiments of the bearing part,
In Fig. 2, both ends of the hole 1S of a bearing 5', which is attached to the end of one seat plate via a pin 13 so as to swing freely, are enlarged to form a trumpet tube shape, so that the swing can be made smooth. can. Further, in FIG. 3, a pair of annular protrusions 20 are provided on the support shaft 2 corresponding to the driving distance between the left and right sides of the lever, and a plate spring 21 with a recess is attached to the hole surface of the bearing 5. The shape of the toilet seat for adults and children can be stabilized by locking the protruding pieces.

FIG. 4 shows a second embodiment of the present invention, and this Western-style toilet bowl has a base 1 that supports a lever 8 at the lower end of a water tank base 22.
4 is installed. The lever 8 has a fulcrum 15 in the center.
The lower end is connected to the support shaft 2 via the pin 23, and the upper end is connected to the pin 2.
3 to arms 24 connected to the bearings 5', and when the lever 8 is operated, only one of the bearings 5' slides along the support shaft 2.

The other bearing 5 is fixed to the support shaft 2 via a locking piece 25, and a stopper 18 is provided at the upper end of the base 14 to stop the lever at two points.

FIG. 5 shows a third embodiment of the present invention, and this Western-style toilet bowl has half right-handed threads and half left-handed threads carved on the support shaft 2 to form a draw rod, and a handle 26 is attached to one end, and a bearing 5.5
A right-hand thread and a left-hand thread are provided on each of the shafts 1 and 2, respectively, so that both bearings can be moved near and far. In this embodiment, the diameter of the toilet seat can be freely changed by turning the handle 26.

〔Effect of the invention〕

Since this invention is configured as described above, it produces the effects described below.

The substantially annular toilet seat is formed from a pair of left and right C-shaped seat plates, each rear end of the pair of seat plates is slidably attached to a support shaft, and the distance between the two can be changed by an attached driving means. The caliber of the toilet seat can be easily changed to one for adults or children by operating the driving means.
It is safe because the child's buttocks do not fall down when using the toilet as in the case of conventional toilets.
