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 toilet seat and a toilet lid tilting device that can be tilted up and down.

[Prior art] Generally, the toilet seat and toilet lid are rotatably supported on the toilet bowl so that they can be raised and lowered freely. It can be rotated. 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 closes slowly.

[Problem to be Solved by the Invention 1] Incidentally, in the above device, in order to standardize parts, the same shock absorber for the toilet seat and the shock absorber for the toilet lid are used. If the weight of the lid is different (the toilet seat is generally heavier) and the resistance of the shock absorber is the same, then if you adjust the resistance of the shock absorber to the heavier object, the lighter object will fall down more slowly. There is a problem that it does not fall or fall.

The present invention has been made in view of the above points, and the object of the present invention is to provide a toilet seat and a toilet lid that can be set to fall down at approximately the same speed even if there is a difference in weight between the toilet seat and the toilet lid. To provide a toilet lid tilting device.

[Means for Solving the Problems] In order to achieve the above object, the toilet seat and toilet lid raising/lowering device of the present invention includes a toilet seat 2 and a toilet lid 3 mounted on the toilet bowl 1 so as to be able to freely raise and lower. The toilet seat hinge shaft 4, which rotates together with the toilet seat 2 when the toilet lid 3 is raised and lowered, is connected to the toilet seat buffer ffl5a, and the toilet lid hinge shaft 6 which rotates together with the toilet lid 3 when the toilet lid 3 is raised and lowered. is connected to a buffer device 5b for the toilet lid, and the buffer devices 5a, 51 for the toilet seat and the toilet lid are connected to a casing 8 loaded with a fluid 7 such as grease, and are rotatably mounted in the casing 8. The body member 9 connected to the toilet seat hinge shaft 4 and the toilet lid hinge shaft 6 collapses within the casing 8 when the toilet seat 2 and the toilet lid 3 are rotated to raise them, and the toilet seat does not receive fluid resistance. A blade 1 is rotatably attached to the outer periphery of the body member 9 so as to stand up within the casing 8 and receive resistance from the fluid 7 when the toilet lid 3 is rotated to fold down the toilet lid 3.
blades 10 of the toilet seat shock absorber 5a to the toilet cover shock absorber 5b in order to adjust the resistance when the toilet seat 2 and the toilet cover 3 fall down due to the difference in weight between the toilet seat 2 and the toilet lid 3. The hole diameter, the number of holes, and the position of the holes can be changed.

Also, due to the difference in weight between the toilet seat 2 and the toilet lid 3, the toilet seat 2 and the toilet lid 3 may
Buffer device for toilet seat 5 to adjust the resistance when it falls over
It is also preferable that the viscosity of the fluid 7, such as grease, placed in the casing 8 of the buffer device 5b for the toilet lid is different from that of the buffer device 5a.

[Operation 1: When rotating the toilet seat 2 or the toilet lid 3 to raise it, the blades 10 of the buffer devices 5a and 51+ fall down and rotate without receiving resistance from the fluid 7, allowing the toilet seat 2 or the toilet lid 3 to be rotated lightly. The shock absorber 5a can be used when the toilet seat 2 or toilet lid 3 is rotated to fold down.

The brake r10 of the toilet seat 5b stands up, the blade 10 rotates under the resistance of the fluid 7, and the toilet seat 2 and toilet lid 3 can be tilted down slowly. Furthermore, even if the weight of the toilet seat 2 or the toilet lid 3 is different, by changing the hole diameter, the number of holes, and the position of the holes provided in the blade 10, the resistance that the blade 10 receives from the fluid 7 can be adjusted. receives resistance according to their weight, and the toilet seat 2 and toilet lid 3 rotate at approximately the same speed and fall down.

[Example] As shown in Fig. 1, a toilet seat 2 and a toilet lid 3 are mounted on the toilet bowl 1 so that they can be raised and lowered by rotation, and a hot water washing device 1] and a low tank 12 are installed around the toilet bowl 1. It is attached. Bearing parts 13 are provided on both sides of the base of the toilet seat 3, and one of the bearings has an irregularly shaped hole 1 in the part 13, which has a partially cut-out circular shape, such as an angular cross section.

Bearing parts 16 are provided on both sides of the base of the toilet lid 3, one bearing has a circular hole 15 in the part 16, and the other bearing has a partially cut-out circular hole 15 in the part 16, etc. An irregularly shaped hole 14 is provided. The toilet seat hinge shaft 4 and the toilet lid hinge shaft 6 have an irregularly shaped cross section with a partially notched circular shape, such as a cross section, and a flange 17 is provided at one end. The toilet seat hinge shaft 4 is arranged on one side, and the bearing is fitted into the irregularly shaped hole 14 of the part 13, and the bearing is rotatably inserted into the round hole 15 of the part 16, so that when the toilet seat 2 is rotated, The toilet seat 2 and the toilet seat hinge shaft 4 are adapted to rotate together.

The toilet lid hinge shaft 6 is arranged on the other side, and the bearing is rotatably inserted into the circular hole 15 of the part 13, and the bearing is fitted into the irregularly shaped hole 14 of the part 16, so that the toilet lid 3 can be rotated. When the toilet lid 3 is opened, the toilet lid hinge shaft 6 rotates together with the toilet lid 3. A shock absorber 5a for the toilet seat is attached to one side of the warm water washing device 1, and a shock absorber 5b for the toilet lid is attached to the other side. The toilet lid shock absorber 51] is connected to the toilet lid hinge shaft 6.

The toilet seat shock absorbing device 5a shown in FIG. 2 and the toilet lid shock absorbing device 5b shown in FIG. 3 have the same structure except that they are arranged symmetrically. The cylindrical casing 8 has one end closed and the other end open, and is provided with an installation island 17 outside the casing 8 for fixing the shock absorbers 5a, 5b.

A circular lid storage space 18 is provided on the side of the opening of the casing 8, and a fluid chamber 19 is provided at the back of the lid storage space 18 of the casing 8, extending approximately half the circumference, and a half-cylindrical fluid chamber 19 is provided in the remaining half circumference. The shaped side bearing is provided with a protrusion 20, and the bearing is provided with a protrusion 21 at the center of the closed end of the casing 8. The body member 9 is formed in a cylindrical shape, and a disc-shaped lid portion 22 is integrally provided at one end of the body member 9. The body member 9 is housed in the casing 8, the lid part 22 is rotatably installed in the lid storage space 18, and the body member 9 is rotatably supported in the side support part 20. The side support at the end of is four parts 23
The side supports are fitted with the protrusion 20. A seal ring 25 such as an O-ring is housed in a storage recess 24 provided around the outer periphery of the lid member 22.
A seal is formed between the outer periphery of the casing 8 and the inner periphery of the casing 8. A partially cut-out circular fitting hole 26 is formed extending from the lid portion 22 into the body member 9.
The toilet seat hinge shaft 4 and the toilet lid hinge shaft 6 can be fitted and connected to the toilet seat hinge shaft 6. A holding plate 27 is disposed in the opening of the casing 8, and a screw receiver provided on the outer periphery of the casing 8 is mounted by screwing a mounting screw 28 from the holding plate 27 into a portion 39. A blade 10 is rotatably attached to the outer periphery of the body member 9 and extends over the entire length of one fluid chamber. A cylindrical shaft portion 30 is provided at the base of the blade 10, and the shaft portion 30 is loosely fitted into a recess 33 with an arcuate cross section provided on the outer periphery of the body member 9, thereby making the blade 10 freely rotatable. . This blade 10 is made of synthetic resin or the like, and a thin wall portion 31 is provided at the tip of the blade 10 over its entire length so as to be orthogonal to the blade 10. A projecting piece 34 is provided adjacent to the recess 33, so that when the blade 10 stands up perpendicular to the body member 9, the blade 10 comes into contact with it and stops. A triangular small protrusion 32 is provided on the inner surface of the fluid chamber 19 of the casing 8 . This small protrusion 32 is provided near where the blade 10 is located when the toilet seat 2 and toilet lid 3 are raised, and is provided only at the back of one fluid chamber (not extending in the depth direction of one fluid chamber). . The fluid chamber 19 is charged with a fluid 7 such as grease. The side support portion 20 is provided with a pair of spring storage recesses 35.
A spring 36 is housed in the spring 36, and the ball 37 placed in the opening of the spring housing recess 35 is biased by the spring 36.

This ball 37 is in elastic contact with the back surface of the lid portion 22 and is adapted to roll along a guide groove 38 on the back surface of the lid portion 22. The part indicated by the symbol A in FIG. 2(a) indicates the direction of the toilet seat 2, and the part indicated by the symbol B in FIG. 3(a) indicates the direction of the toilet lid 3. However, toilet seat 2 and toilet lid 3
When the body member 9 rotates in the direction of the arrow in FIG. 2(,) or in the convex direction of the arrow in FIG. 3(a), the blade 10 falls down as shown in the imaginary line. It rotates with almost no resistance from the fluid 7, and the toilet seat 2 and toilet lid 3 can be rotated and raised 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(a) and in the two directions of arrows 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. 3゛ slowly rotates and falls down.

By the way, in the present invention, the cushioning device 5a for the toilet seat and the cushioning device 5) for the toilet lid have the same structure, but the toilet seat 2
Since the weight of the toilet seat 2 and the toilet lid 3 are different, we cannot expect the same cushioning effect (generally, the toilet seat 2 is heavier than the toilet lid 3, and if the resistance of the cushioning device of the toilet seat 2 is not adjusted at the moment, then in the case of the toilet lid 3) If the resistance is large, the falling speed may be slow or the object may not fall at all). Therefore, when providing the hole 40 in the blade 10 as shown in FIG. 5, the diameter of the hole 40 may be changed or
By changing the number of 0's and changing the position of the holes 40, 1 (the more the holes 40 are placed outside in the radial direction, the lower the resistance). Thereby, the resistance can be adjusted according to the toilet seat 2 and the toilet lid 3, and the toilet seat 2 and the toilet lid 3 can be tilted down at a substantially constant speed. Also, as an alternative means, a buffer device 5 at 5
It is also possible to change the viscosity of the fluid 7 introduced into the fluid chamber 19 of b. That is, the viscosity of the heavier fluid 7 between the toilet seat 2 and the toilet lid 3 is increased, and the viscosity of the lighter fluid 7 is decreased.

This also allows the toilet seat 2 and the toilet seat 3 to be tilted at a substantially constant speed by changing the resistance.

[Effects of the Invention] Since the present invention is configured as described above, when the toilet seat or toilet A is rotated to raise it, the blade of the shock absorber falls down and rotates without receiving resistance from the fluid, and the toilet seat or toilet A is rotated without being subjected to resistance from fluid. The toilet lid can be raised by lightly rotating it, and when the toilet seat or toilet lid is rotated to fold down, the blade of the shock absorber is raised and the blade rotates due to the resistance of the fluid, causing the toilet seat and toilet lid to rise. The lid can be tilted down slowly, and the toilet seat or lid does not fall down suddenly and make a loud noise like conventional methods. In order to adjust the resistance of the toilet seat shock absorber and toilet lid shock absorber, the hole diameter, number and position of the holes are changed in the blades of the toilet seat shock absorber and toilet lid shock absorber. Even if the same blade is used, the resistance that the blade receives from the fluid can be easily adjusted to match the weight of the toilet seat or toilet lid, and the toilet seat or toilet lid can be rotated at a nearly constant speed and tilted down. It is something.

Furthermore, the invention according to claim 2 of the present invention provides a cushioning device for the toilet seat and a cushioning device for the toilet lid to adjust the resistance when the toilet seat and the toilet lid fall down due to the difference in weight between the toilet seat and the toilet lid. Since the viscosity of the fluid such as grease that is put into the casing of the device is different, the resistance that the blade receives from the fluid can be easily changed by simply changing the fluid that is put into the casing. It is something that can be used as resistance.
