Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention allows the toilet seat and the toilet lid to be brought down slowly and cushioned when they are put down on the toilet bowl, and the toilet seat and the toilet lid to be raised up easily. This invention relates to a device for raising and lowering the toilet seat and lid of a toilet bowl.

[Prior art] The toilet seat and toilet lid are rotatably supported on the toilet bowl in a single shell so that they can be raised and lowered freely. can be rotated easily. Therefore, when you put down the toilet seat or toilet lid from an upright position, you need to put your hand on it and turn it all the way, but the back of the toilet seat and toilet lid feels dirty and I don't want to touch it, so I put my hand all the way. There are some things that cannot be added. For this reason, the toilet seat or toilet lid may fall off due to letting go of the toilet, or because it is difficult to hold the toilet, and the toilet seat or lid may fall, creating a problem of making a loud noise.

In order to solve this problem, the present applicant previously applied for the
No. 3-8461]. This system connects a shock absorbing device to the hinge shaft that rotates together with the toilet seat and toilet lid, so that when the toilet seat or toilet lid is folded down, it is cushioned and rotates slowly.
The toilet seat and toilet lid are designed to rotate lightly when raised.

This shock absorber has a body member connected to a hinge shaft rotatably mounted inside a casing, and a fluid such as grease is filled in the space between the inner periphery of the casing and the outer periphery of the body member. It is formed by rotatably attaching two blades. When the toilet seat or toilet lid is rotated in the direction of raising it, the blade falls down along the outer surface of the body member, and the body member rotates without receiving much resistance from the fluid, turning the toilet seat or toilet lid relatively lightly. When the toilet seat or toilet lid is rotated in the direction of folding down, the blade stands up perpendicular to the outer surface of the body member, and the body member rotates as the blade receives the resistance of the fluid, and the toilet seat or toilet lid is rotated. It seems to be falling down slowly.

[Problems to be Solved by the Invention] However, in the conventional example described above, when the toilet seat or toilet lid is rotated from the upright position to the direction of folding down, the toilet seat or toilet lid rotates slowly due to resistance. When an unexpected external force is applied while the toilet is upright and the toilet seat or toilet lid falls over due to its own weight, it will simply fall over. In other words, there was no stopper mechanism to prevent the toilet seat or lid from falling over when an unexpected external force was applied to them while they were in the upright position.

The present invention has been made in view of the above points, and an object of the present invention is that when the toilet seat (toilet lid) is upright, the rolling ball is located in the stopper groove, and an unexpected external force is generated. To provide a device for raising and lowering a toilet seat and a lid of a toilet bowl, which does not have the disadvantage of easily falling over and can compactly incorporate a stopper mechanism into a shock absorbing device.

[Means for Solving the Problems 1] In order to achieve the above object, the toilet seat and toilet lid raising/lowering device of the present invention includes a toilet seat (toilet lid) 2 and 3 mounted on the toilet bowl 1 so as to be able to be raised and lowered, Toilet seat (toilet i) 2. Toilet seat (toilet lid) by raising and lowering 3.
The toilet seat (toilet lid) hinge shafts 4, 6 that rotate together with the toilet seats (toilet lids) are connected to the toilet seat (toilet lid) shock absorbers 5a, 51r3-, and the toilet seat (toilet lid) shock absorbers 5a, 5b are connected to the toilet seat (toilet lid) shock absorbers 5a, 51r3-. , a casing 8 loaded with a fluid 7 such as grease, a body member 9 rotatably mounted in the casing 8 and connected to the toilet seat hinge shafts 4 and 6, and a toilet seat (toilet!) 2. −
When the toilet seats (toilet lids) 2 and 3 are rotated so as to stand up, they fall down within the casing 8 and do not receive any resistance from the fluid. The body member 9 is provided with a flange 22, and a rolling ball 37a that rolls along the flange 22 is attached to the casing 8. The flange 22 is provided with a recessed groove 38a, into which a rolling ball 37a is fitted when the toilet seat (toilet lid) 2, 3 is in the upright position by a spring 36 provided therein. It is characterized by

[1] When the toilet seat (toilet lid) 2.3 is rotated to raise it, the blades 10 of the shock absorbers 5a, 5b fall down and the fluid 7
The toilet seat (toilet lid) 2゜3 can be rotated lightly and raised without receiving any resistance, and when the toilet seat (toilet lid) 2 and 3 are rotated to fold down, there is a cushion on the outside. The blades 10 of the devices 5a and 5b stand up, and the blades 10 rotate under the resistance of the fluid 7, allowing the toilet seat (toilet lid) 2.degree. 3 to be tilted down slowly. When the toilet seat (toilet lid) 2°3 is raised, the rolling ball 37a fits into the stopper groove 38a, and when the toilet seat (toilet lid) 2, 3 is folded down, the rolling ball 37a fits into the stopper groove 38a. If you do not apply any force that would cause the toilet seat to fall out, the toilet seat (toilet lid) will not rotate to a position where it will fall under its own weight, and the toilet seat (toilet lid) will not easily fall over due to unexpected external force.

This is provided. Both ends of the stopper groove 38a are raised parts 41, and the end of the rolling guide groove 38a on the stopper groove 38a side is a gentle slope part 4.
2, and the end of the auxiliary rolling idle groove 38c on the rolling guide groove 381 side forms a gentle slope portion 42.

The part indicated by the symbol B in FIG. 2(a) indicates the direction of the toilet seat 2, and the part indicated by the symbol B in FIG. 3(,) indicates the direction of the toilet lid 3. When the toilet seat 2 and toilet lid 3 are rotated to raise them, the body member 9 rotates in the direction of the arrow in FIG. 2(a) and in the convex direction of the arrow in FIG.
falls down as shown in the imaginary line, rotates with almost no resistance from the fluid 7, and can raise the toilet seat 2 and toilet lid 3 by rotating them with a light force. Further, when the toilet seat 2 and the toilet lid 3 are rotated so as to be tilted down, the body member 9 is rotated in the direction of arrow A in FIG. 2 (,) and in the direction of arrow A in FIG. 3 (,). At this time, the thin part 31 of the blade 10 is initially in contact with the small protrusion 32, and as the thin part 31 moves away from the small protrusion 32, the blade 10
stands up, the blade 10 receives resistance while standing up,
The toilet seat 2 and toilet lid 3 slowly rotate and fall down.

Toilet seat 2 performs the actions of raising and lowering toilet seat 2 and toilet lid 3.
A more detailed explanation using an example is as follows. Figure 7 (
, ) is the state in which the toilet seat 2 is laid down horizontally, and the rolling ball 3
7a is located in the rolling guide concave groove 38b, and the auxiliary rolling ball 37b is located in the auxiliary rolling guide groove 38c. From this state, lift the toilet seat 2 upwards as shown in Figure 7 (
The toilet seat 2 rotates as shown in b). At this time, the outer blade 10 has fallen down, and the toilet seat 2 can be raised without resistance. When the toilet seat 2 is raised to the state shown in FIG. 7(b), the rolling ball 37a and the auxiliary rolling ball 37I) move into the rolling guide = 1]
- It is located at the end of the concave groove 381) and the auxiliary rolling guide concave groove 38c, and from this state it goes over the peak between the concave grooves (the surface that is flush with the back surface of the 7-lamp 22). At this time, since there is a slope portion 42 at the end of the rolling guide groove 381) and the auxiliary rolling guide groove 38c, the rolling guide smoothly rolls over the mountain portion. When the toilet seat 2 is raised all the way up, the thin section 31 at the tip of the blade 10 hits the small protrusion 32 and becomes balanced, as shown in FIG. 7(C). When the toilet seat 2 is further rotated in the rising direction from this state, the thin portion 31 of the blade 10 rises up to the small protrusion 32, resulting in an upright state as shown in FIG. 7(d). Thin wall part 3
1 is raised to the small protrusion 32, the thin portion 31 is separated from the inner surface of the casing 8. At this time, since the small protrusion 32 is only partially provided at the back of the fluid chamber 19, a gap is created over substantially the entire length of the blade 10, excluding the portion where the small protrusion 32 is located, through which the fluid 7 can pass. When the state is in an equilibrium state as shown in FIG. 7(c) or in an upright state as shown in FIG. 7(d), the rolling ball 37a fits into the stopper groove 38a and the auxiliary rolling ball 371 rolls. 〃Id groove 38
1) 2- Get stuck in. When folding the toilet seat 2, force is applied in the direction of folding the toilet seat 2, and the toilet seat 2 is rotated as shown in FIG. 7(d), FIG. 7(c), and FIG. 7(b). At this time, between the state shown in FIG. 7(d) and the equilibrium state shown in FIG. 7(e), the thin wall g of the blade 10 is
31 rests on the small protrusion 32, and the thin part 31 is separated from the inner surface of the casing 8, so it rotates with almost no resistance.
When the blade 10 rotates lightly to an equilibrium state and reaches a position where it exceeds the equilibrium state and rotates under its own weight, the blade 10 stands up and the thin section 3
1 comes into elastic contact with the inner surface of the casing 8, rotates while receiving resistance, and is cushioned and falls down until the toilet seat 2 becomes horizontal as shown in FIG. 7(a). Since the toilet seat 2 rotates lightly with almost no resistance from the upright state as shown in Figure 7(d) to the equilibrium state as shown in Figure 7(c), there is no need to accidentally push the toilet seat 2 over. However, in the state shown in FIG. 7(d) or FIG. 7(C), the rolling ball 37a is located in the stopper groove 38a, and the toilet seat 2 is moved from the equilibrium state. When rotating to a position where it falls down due to its own weight, the rolling ball 37a and the auxiliary rolling ball 37I) have to go over the peak, and are prevented from rotating due to large resistance. Therefore, when the toilet seat 2 is toppled, the toilet seat 2 must be consciously pushed with more than a certain amount of force, and the toilet seat 2 can be prevented from falling due to an unexpected external force.

[Effect of the invention] Since the present invention is configured as described above, the toilet seat (toilet lid)
When the toilet seat (toilet lid) is rotated to raise it, the blade of the shock absorber collapses and rotates without receiving resistance from the fluid, allowing the toilet seat (toilet lid) to be rotated lightly and raised.
When the toilet seat (toilet bowl) is tilted down, the blade of the shock absorber stands up and rotates due to the resistance of the fluid, allowing the toilet seat (toilet bowl) to be tilted down slowly. Not only does it not make a loud noise when the toilet seat (toilet lid) falls suddenly, but it also has a flange on the body member, and a rolling ball that rolls along the flange is elastically biased by a spring installed in the casing to raise the toilet seat (toilet lid). The flange has a groove for a stopper into which the rolling ball fits when the ball is in the upright position.
Unless you consciously apply force that causes the rolling ball to come out of the stopper groove when tilting the toilet seat (toilet lid), the toilet seat (toilet lid) will not work properly.
The toilet seat (toilet lid) cannot be rotated due to its own weight, and can prevent the toilet seat (toilet lid) from tipping over due to unexpected external force.Moreover, it incorporates rolling balls and springs into the shock absorbing device, and has a groove for a stopper on the flange. The stopper mechanism can be constructed simply by providing the stopper mechanism, and the stopper mechanism can be constructed inexpensively and compactly.
