Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a toilet seat device, particularly to a toilet seat device having a toilet seat rotatably attached to the toilet main body side with a hinge pin.

This type of device, which is generally well known, lifts the toilet seat placed horizontally on the top of the toilet bowl body when standing up to urinate, and rotates the seat to a substantially upright position using a hinge pin as a rotational fulcrum. The toilet seat is held in an upright position to urinate.However, in order to maintain the toilet seat in this approximately upright position, the center of gravity of the toilet seat must be moved from the vertical line of the hinge pin when the toilet seat is in this approximately upright position. The structure also had to be located on the other side of the turnover, which had the disadvantage of having many design constraints.

Therefore, an object of the present invention is to maintain the toilet seat in an approximately upright state without being restricted by the positional relationship between the center of gravity of the toilet seat and the hinge pin.

In order to achieve this purpose, a toilet seat is provided which is placed on the rear part of the toilet bowl body and includes a box part which is laterally provided with a left end face and a right end face, a left rear part and a right rear part, and the left rear part of the toilet seat is connected to the box part. A left hinge pin pivotally attached to the left end surface, a right hinge pin pivotally attaching the right rear end of the toilet seat to the right end surface of the box section, and a protrusion fixed to the left end surface of the box section and guiding the left rear end of the toilet seat. a left cam fixed to the right end surface of the box portion and a right cam having a protrusion that guides the right rear portion of the toilet seat, and the amount of protrusion of each of the protrusions depends on the lifting and rotation angle of the toilet seat. The basic configuration of the present invention is that it is configured to be proportional.

Therefore, with this configuration of the present invention, when the toilet seat reaches a substantially upright state, it engages with the protrusion of the cam, and
A frictional engagement force is applied, and this frictional engagement force causes
The toilet seat can be maintained in a substantially upright state, achieving the initial purpose, and the toilet seat rotates smoothly when not in the substantially upright state, requiring little operating force, and opening and closing the toilet seat is very easy. In addition, since the cam is supported by the hinge pin, there is no need to provide a member for attaching the cam, which provides excellent practical effects.

An embodiment of the device of the present invention will be described below with reference to the drawings.

Hinge pin 1 is attached to the box part 10 on the toilet main body side.
1, a toilet seat 12 and a toilet lid 13 are rotatably attached as shown in FIG. It is possible that the toilet seat 12
A cam 14 made of synthetic resin supported by a hinge pin 11 is disposed between the toilet seat 12 and the box portion 10 in order to maintain the toilet seat 12 in an approximately upright state. Since the toilet seat 12 is pivotally connected at both ends, the cam 14 is also attached to both the left and right sides of the toilet seat 12 (in the left and right direction, the toilet seat 1
2 toward the box section 10. )
3 and 4 show the cam 14 provided on the left side, and FIGS. 5 and 6 show the cam 14 provided on the right side. The cam 14 used on either the left or right side has a protrusion 15 that presses against the toilet seat 12 and a hinge pin 11 passes through it.
A key portion 17 is formed on the back side of the surface on which the protruding portion 15 is formed, and the key portion 17 is protruded from the hole 16.
This key portion 17 is fitted into a groove formed in the box portion 10 to prevent the cam 14 from rotating. The hinge pin 11 supporting the toilet seat 12 and the cam 14 is the toilet seat 12
The hinge pin 11 is held in the box part 10 by the E-ring 18 with the hinge pin 11 held in a horizontal state so as not to contact the protruding part 15 of the cam 14.

Therefore, when the toilet seat 12 is rotated from a horizontal state to an approximately upright state, the portion of the toilet seat 12 near the hinge pin 11 is exposed to the protruding portions 1 of the cams 14 disposed on both the left and right sides.
5, the protrusion 15
At this time, a frictional engagement force is applied to the toilet seat 12, so that the toilet seat 12 can be held in its substantially upright state.

Also, in order to return the toilet seat 12 to the horizontal state, the cam 14
What is necessary is to apply an acting force that exceeds the frictional engagement force applied at , and apply that acting force in the horizontal direction.
