Description

[Detailed explanation of the idea] "Industrial application field" This proposal concerns a toilet seat opening/closing device.

``Prior art'' Conventionally, when opening and closing the toilet seat and lid of a Western-style toilet, when a man urinates, the toilet seat and lid are opened and closed at the same time.
When a woman uses the toilet, only the lid is opened and closed, so the toilet seat or lid must be held directly with the hand, making it unclean or giving a feeling of uncleanness. Therefore, various toilet seat opening/closing devices were developed (Utility Model Publication No. 49-26343, Utility Model Publication No. 49-28358,
Jikko No. 50-1545).

However, since it was difficult to easily attach these opening/closing devices to existing toilet seats, the inventor of the present application developed a toilet seat opening/closing device that could be installed extremely easily (Utility Model Application No. 138498/1983), but it was difficult to attach the lid to the existing toilet seat. When the lid was opened, the opening/closing arm rotated downward under its own weight and was unable to maintain its position, causing an accident in which the claw collided with the toilet seat and broke when the lid was closed.
Another problem is that it is difficult to determine the engagement position between the claw and the bottom surface of the toilet seat, and skill is required to open the lid and the toilet seat at the same time.

"Problems to be Solved by the Invention" The present invention is to provide a toilet seat opening/closing device that prevents the arm from rotating due to its own weight when the lid is open, and also allows the claws to easily engage with the bottom surface of the toilet seat, making it easy to use. The purpose is to

"Means for Solving Problems" In order to achieve this objective, the present invention provides a Western-style toilet that is equipped with a toilet seat and a lid that can be opened and closed, and a fitting that can be attached to the back of the lid to connect the lid and the toilet seat. The base of an arm extending outward from between is supported by a pin so as to be rotatable along the outer edge of the lid, and a claw is provided in the middle of the arm to go in and out of the underside of the toilet seat. The inner edge intersects the rotating circumference of the claw around the pin, and the claw enters the bottom surface of the toilet seat at the intersection, and protrudes from the bottom surface at the portion where the inner edge deviates from the circumference. , a toilet seat opening/closing device is specially devised, which is provided with a mechanism for stopping rotation of the arm in the out and in states and a self-holding device in the stopped state at least in the out state, and a fitting can be attached to the back side of the lid with adhesive. The above specific idea formed.

In the above-described specific invention, the rotation stop mechanism has a stopper surface formed on the fixture and a cam surface that intersects with the stopper surface on the base.

And according to the above-mentioned specific device, the stop state self-holding device is formed by a ball that presses into contact with the sliding surface of the fixture and the base by a spring, and a receiving part of the ball that is recessed in the sliding surface. Therefore, it is constructed as follows.

"Operation" Therefore, when the opening of the toilet bowl 15 is closed with the toilet seat 2 and the lid 1, grasp the outer end 4'' of the arm 4 protruding outward from between the toilet seat 2 and the lid 1, and press the pin 5.
When the toilet seat 2 is rotated in one direction until it stops, the pawl 6 is rotated at the intersection between the inner edge 2' of the toilet seat 2 and the rotating circumference of the pawl 6.
engages with the lower surface of the toilet seat 2, so when the outer end 4'' of the arm 4 is grasped and lifted up, the lid 1 and the toilet seat 2 are opened simultaneously (Fig. 5).Also, the lid 1 and the toilet seat 2 are opened simultaneously. In the closed state, if you grip the outer end 4'' of the arm 4 and rotate it in the opposite direction until it stops, the claw 6 will come off the toilet seat 2, so if you grip the outer end 4'' and lift it upward, only the lid 1 will open. In this state, the stopping position of the arm 4 is self-held by the spherical body 13 pressed against the receiving part 14, so the arm 4 does not rotate downward due to its own weight (Fig. 4 shows this state). show).

``Embodiment'' In a Western-style toilet bowl 15 comprising a toilet seat 2 and a lid 1 that can be opened and closed, the toilet seat 2 and the lid 1 are pivotally supported on the rear upper surface of the opening of the toilet bowl 15 by horizontal pins 16, 16 so that they can be opened and closed. The toilet seat 2 has a substantially oval shape as shown in FIG. 4, but it may also have a horseshoe shape with the front portion cut away. The outer edge of the lid 1 coincides with the outer edge of the toilet seat 2, and the inner edge 2' of the toilet seat 2 is approximately oval. The base 4' of an arm 4 is pivotally supported by a pin 5 on a heart-shaped fixture 3 which can be adhered to the back surface of the lid 1 with adhesive, and the arm 4 is placed between the lid 1 and the toilet seat 2. A gripping tool 4 is provided at the extended outer end 4'' extending outward from the
It is supported so as to be rotatable in a reciprocating manner along the outer edge of the lid 1 around a pin 5. In the middle of this arm 4 is the toilet seat 2.
A claw 6 that goes in and out of the bottom surface is provided, and the inner edge 2' of the toilet seat 2 intersects with the rotating circumference of the claw 6 about the pin 5, and the claw 6 enters the bottom surface of the toilet seat 2 at the intersection. The inner edge 2' protrudes from the lower surface at a portion outside the circumference. There is no problem in forming a notch 2'' in the toilet seat 2 at this detached portion.Then, in this extended and inserted state, the arm 4
A mechanism 7 is provided for stopping the rotation of the arm 4, and the mechanism 7 comes into contact with the stopper surface 9 formed on the fixture 3 and the base 4' of the arm 4 to stop the rotation of the arm 4. The cam surfaces 10, 10' are formed to cross each other. In addition, at least in the above-mentioned extended state (the state shown by the imaginary line in Figure 2), the arm 4 is provided with a self-holding device 8 for the stopped state of the arm 4, but this is also provided in the inserted state (the state shown by the solid line in Figure 2). There is no problem. This self-holding device 8 is provided with a spherical body 13 that is pressed against one of the sliding surfaces 11, 11' between the fixture 3 and the base 4' by a spring 12, and the spherical body 13 is recessed in the sliding surface 11. The spherical body 13 is formed by the receiving portion 14 of the body 13, and the spherical body 13 may be a hemisphere as shown in FIG. 3 or a sphere (ball). In addition, what is indicated by 17 in the figure is the support hole of the spring 12,
18 is a stainless steel piece forming the receiving part 14; 19
1 is a cushion material provided on the claw 6, and 1' is a notch formed on the outer edge of the lid 1 for rotating the arm 4.

"Effect" Since this project is configured as described above, the claw 6 is connected to the toilet seat 2.
The lid 1 can be easily stopped in the position where it is disengaged from the toilet seat 2 and the position where it is engaged with the toilet seat 2, and no skill is required to engage and separate the claw 6 from the toilet seat 2, and the lid 1 can be opened by removing the claw 6 from the toilet seat 2. To open and close a toilet seat that is easy to use and safe, in which the arm 4 is self-held in that position and is prevented from rotating downward due to its own weight when the lid 1 is closed, and there is no risk of the claw 6 colliding with the toilet seat 2 and damaging it when the lid 1 is closed. There is an advantage that not only a device is obtained, but also that it can be easily attached to the back surface of the lid 1 with an adhesive.
