[0007]

[Effect]

The above means works as follows. In other words, the elastic body placed on the hinge axis is The toilet seat is biased upward, but when the user sits on the toilet seat, the toilet seat is pressed against the top of the toilet bowl. In order to make stable contact, it sinks downward along the elongated hole against the biasing force of the elastic body. Also , when rotating the toilet seat, the elastic body urges the hinge shaft to one side of the elongated hole, so the hinge The shaft does not move through the elongated hole, preventing wobbling.

[0008]

【Example】

An embodiment of the present invention will be described with reference to FIGS. 1 to 3. In this example, human body private parts are washed. The present invention relates to a toilet seat device used in the device. As shown in Figure 1, the rear end of toilet bowl 1 A base cover 4 containing a human body private parts cleaning device is disposed on the upper surface of the body. child The base cover 4 is U-shaped and opens toward the toilet bowl 1 side. placed on the top of toilet bowl 1. A pair of hinges are provided at the rear ends of the toilet seat 2 and toilet lid 3. The toilet seat 2 and the toilet lid 3 are connected to the U-shaped base cover 4 by the hinge part of the base cover 4. It is rotatably supported inside the surface. Rubber legs are attached to the bottom of the toilet seat 2. (Figure 3). In this embodiment, the front legs 7 are on the front side, and the hind legs 8 are on the back side. Two of them are attached to buffer the shock caused by the contact between the toilet seat 2 and the toilet bowl 1.

[0009] Next, the hinge portions of the toilet seat 2 and toilet lid 3 will be explained. Figure 2 shows the B-B line in Figure 1. A cross-sectional view along . A pair of elongated holes 2a are located on both sides of the rear end of the toilet seat 2 (see Figure 2). (shown in the figure) is bored, and the cross section of the elongated hole 2a is elongated in the vertical direction. . Additionally, a pair of hinge holes 3a (only one side is shown in Figure 2) are provided on both sides of the rear end of the toilet lid 3. Unlike the long hole 2a, the hinge hole 3a has a circular cross section.

0010 A hinge shaft 5 is inserted into the elongated hole 2a and the hinge hole 3a. hinge shaft 5 The diameter is approximately the same as the hinge hole 3a of the toilet lid 3, and it is slidably and loosely fitted into the hinge hole 3a. It is. Furthermore, an elastic body 6 made of resin is disposed between the hinge shaft 5 and the elongated hole 2a. It is set up. The elastic body 6 pushes the toilet seat 2 upward by urging the elongated hole 2a upward. is energized. A flange portion 5a is formed at one end of the hinge shaft 5. The diameter of the hinge portion 5a is larger than the diameter of the long hole 2a in the longitudinal direction. Hinge shaft 5 The other end protrudes from the hinge hole 3a and has a hole 4a drilled in the base cover 4. has been incorporated into. A washer 9 fits into the end of the hinge shaft 5 passing through the hole 4a. Further, an E-type retaining ring 10 is fixed on the outside to prevent the washer 9 from falling off. are doing. The washer 9 and the flange portion 5a allow the hinge shaft 5 to be moved in the left and right direction. It is positioned so that it does not move. In this way, the hinge shaft 5 The toilet seat 2 and the toilet lid 3 are rotatably supported on a base cover 4. Toilet seat device of this example , the elastic body 6 urges the toilet seat 2 upward, and the toilet seat 2 is placed on the toilet bowl 1. When the toilet seat 2 is opened, it is arranged so that there is a slight gap a (Fig. 3) between the rear legs 8 of the toilet seat 2 and the toilet bowl 1. has been done.

[0011] Next, the operation of this embodiment will be explained based on FIG. 3. When you lower the toilet seat 2 onto the toilet bowl 1, The front legs 7 of the toilet seat 2 come into contact with the toilet bowl 1 and stop. At this time, as mentioned above, the elastic body 6 The toilet seat 2 is urged upward between the elongated hole 2a and the hinge shaft 5. Flight in this condition When a user sits on the top surface of the seat 2, the toilet seat 2 is biased downward, and the elongated hole 2a of the toilet seat 2 is closed. It moves downward along the outer periphery of the hinge shaft 5 against the biasing force of the elastic body 6. instructor As a result, the rear end of the toilet seat 2 sinks, and the rear legs 8 also come into contact with the toilet bowl 1, causing the toilet seat 2 to The toilet bowl 1 is stabilized without putting a burden on the hinge part at the rear end.

0012 When opening the toilet seat 2, the toilet seat 2 rotates around the hinge shaft 5. With long hole 2a An elastic body 6 disposed between the hinge shaft 5 and the toilet seat 2 moves in the vertical direction of the elongated hole 2a. We will encourage you not to do so. In this way, even when the toilet seat 2 is rotated, it does not wobble. Therefore, the toilet seat 2 can be opened and closed smoothly.

[0013] In this example, an elastic body is placed between the elongated hole and the hinge shaft so that the toilet seat is always attached upward. The toilet seat is unique in its structure, with a long hole drilled in the rear end of the seat and a hinge shaft attached to the base cover. Although the case where it is fixed has been explained, according to the present invention, a long hole is formed in the base cover and the hinge is fixed. A similar effect can be obtained by fixing the shaft to the toilet seat. In addition, the elastic body 6 is made of resin. It can be applied not only to objects made of metal but also to objects made of metal.

[0014]

[Effect of the idea]

According to the present invention, the elastic body is placed between the elongated hole and the hinge shaft to keep the toilet seat always upward. Because the toilet seat is biased, the hinge part of the toilet seat is arranged to be able to move slightly up and down. Even if the seat is not necessarily positioned stably relative to the toilet bowl, the user may strain the toilet seat. When the toilet seat is turned on, the toilet seat moves downward against the biasing force of the elastic body and sits stably on the toilet bowl. It can be placed on the ground without causing any strain on the hinge part of the toilet seat, and prevents damage to the hinge part. At the same time, the urging force of the elastic body prevents the toilet seat from being hinged against the elongated hole when opening and closing. The axis does not move up or down. For this reason, even though the hole into which the hinge shaft is inserted is an elongated hole, Nevertheless, the occurrence of rattling can be prevented.
