The present invention relates to a suitable opening and closing device for use in opening and closing of the lid and seat of the culture toilet.

[Prior art]

Conventionally, this type of switchgear includes a toilet lid attached through a hinge pin to a bracket fixed to the toilet body in order to keep a toilet lid or a toilet seat stable in an open state so that it does not drop rapidly when closed. It is known that the torsion spring is rolled up around the hinge pin between the toilet seat and the bracket.

[Problem to Solve Invention]

The torsion spring itself has a deviation in torque, and since the torque is linearly increased and decreased, it is necessary to compensate for the deviation of the torque.In addition, when the torque of the torsion spring is strong, the torsion spring is not sufficiently closed, such as the seat of the toilet seat, and thus slightly rises. If there is a feeling and the torque is weak, there is a problem that the self-supporting state is not stable in the open state.

It is an object of the present invention to exclude the damper action when opening the lid or seat of the culture toilet to be opened lightly by less or less, to maintain a stable in the self-supporting state and to close softly by the damper action when closed It is also intended to provide an innovative switchgear so that the damper mechanism is not destroyed by overload.

[Means for solving the problem]

In order to achieve the above object, the present invention is a shaft having a structure attached to one end to the bracket attached to the valve body, and the shaft is inserted into the shaft in the axial direction in order to maintain the toilet seat or the seat to slide slightly in the axial direction A compression spring which is wound around the rotating drum and the rotating drum attached to be movable and rotatable, and slides and presses the rotating drum which is installed between the shaft and the rotating drum in one direction, and the shaft and the rotating drum; It consists of a damper mechanism which has a valve provided in between.

At this time, the present invention can install the cam mechanism using the elasticity of the compression spring to control the rotation of the rotating drum.

The present invention provides a pair of valves in which a damper mechanism is provided on a shaft, a cylinder portion provided inside the rotating drum with the valve mounted therein, a viscous fluid filled between the cylinder portion and the valve, and installed in the rotating drum. Compression consisting of a wing that reaches the shaft surface through the cylinder, or a slide member mounted on the shaft so that the cam mechanism becomes a sliding material by itself, and a sliding compression to press the slide member and the rotating drum together in one direction. The concave part or convex part provided in the spring side, the one end surface side of a slide member, and this concave part or convex part provided in the rotating drum side so that it may fit by a convex part and a rotation angle can be comprised.

The present invention provides a shaft including a first shaft portion having a flange portion, a portion protruding from one end of the flange portion fixed to the bracket side, and a portion protruding from the other end of the flange portion in the rotating drum; 1 pair of 1st valve piece and 2nd valve piece which consisted of the 2nd shaft part fixed to the axial direction of the 1st shaft part, or the valve protruded from the shaft, and the 1st cut-out result provided in the 1st valve piece, and the 2nd valve Of the valve plate which is installed in the long groove provided in the piece, the second cutout substantially coinciding with the first cutout, and the partition plate provided in the rotary drum, the valve plate stored in the long groove provided in the axial direction between the first valve piece and the second valve piece.

EXAMPLE

Embodiment 1 of the present invention is shown in the drawings, and in Figs. 1 to 2, 1 is a valve body and 2 is a water tank. A pair of brackets 3 and 3 are fixed to both sides of the upper rear side of the toilet body 1, and a toilet lid (4a and 4b) is connected to the brackets 3 and 3 through a pair of opening and closing devices 4a and 4b. 5) or sitting seat (6) is attached to the valve body with opening and closing material. That is, each side 5a, 6b of each attachment part 5a, 5b, 6a, 6b of the toilet seat lid 5 and the seat 6 is a later-described rotary drum 7 as shown in FIG. By engaging the protrusions 7a and 8a protruding on the outer circumference of 8, with the engaging grooves 5b and 6c, they are fixed to the rotary drums 7 and 8, but the other attachment portions 5b and 6a The rotating drums 8 and 7 are supported by a rotating material. Due to this fact, at the time of opening and closing the toilet lid 5 or the seat 6, one of the pair of opening and closing devices 4a and 4b is rotated and the rotary drums 7 and 8 operate.

3 to 9 show the internal structure of the toilet lid opening and closing device 4a and its function. The left side opening and closing device 4a of FIG. 2 will be described below, but the structure of the right side opening and closing device 4b is also different as described later, and others are the same.

In the figure, g is a shaft, and the shaft 9 is a first shaft portion 10 and a second shaft portion 12, and the first shaft portion 10 is a deformation hole provided in the bracket 3. ( It is fixed to the bracket 3 by inserting the attachment part 10a comprised in the same shape as the deformation | transformation hole 3a in the shape of 3a. The second shaft portion 12 is fitted with an end portion 10c fitted into the bearing hole 10d provided in the axial direction of the first shaft portion 10. The first shaft portion 10 is composed of a flange portion 10b and an insertion portion 10e sequentially installed in the axial direction after the attachment portion 10a, and an insertion portion 10e inserted into the rotary drum 7. And the inner circumferential wall of the rotating drum 7 are sealed by seal members 11 and 13 such as O rings.

Next, the damper mechanism 16 will be described. The second shaft portion 12 is provided with a pair of valves 17 and 17 at positions substantially opposite to the central portion thereof, and the valves 17 and 17 are formed on the inner circumferential wall of the rotary drum 7 and the first shaft portion ( It is in contact with the partition wall 18 which protrudes in the edge part of the insertion part 10e side of 10), and inside of the rotating drum 7. As shown in FIG. In particular, the valves 17 and 17 are formed by the first valve pieces 20 and 20 and the second valve pieces 22 and 22 partitioned by elongated grooves 19 and 19 provided in the central axial direction, as shown in FIG. And valve plates 23 and 23 stored in the long grooves 19 and 19 and arcuate grooves 18a and 18a provided in the partition wall 18, and on the outside of the first valve pieces 20 and 20. The first notches 21 and 21 are provided, and the second valve pieces 22 and 22 on the other side are provided with long holes 15 and 15 extending in the axial direction and the first notches on the valve plates 23 and 23. Second notches 24 and 24 having the same size as 21 and 21 are provided. The pair of cylinders 25a, 25a partitioned by the valves 17, 17 at the portion where the valves 17, 17 of the rotary drum 7 are accommodated has a pair of wings 7b, 7b on the inner circumferential wall. It protrudes and is in contact with the surface of the 2nd shaft part 12 through the cylinder parts 25a and 25a. The cylinder portions 25a and 25a are filled with a viscous fluid 26 such as silicone oil. Both ends of the wing portions 7b and 7b are in contact with the end faces of the partition wall 18 and the insertion portion 10e of the first shaft portion 10.

Between the outer circumference of the second shaft portion 12 and the partition wall 18 is sealed with a sealing member 27 such as an O-ring, and at the end of the second shaft portion 12, a spring receiving member 28 is provided with an attachment screw ( 29. The slide member 30 is attached to the small-diameter portion 12a at a position opposite to the spring receiving member 28, in a non-rotating state. The compression spring 31 is rolled up between the spring receiving member 28 and the slide member 30 while being wound around the small diameter portion 12a. And a stopper at the end of the rotary drum (7) (32) is attached and sealed between this stopper (32) and the rotating drum (7) by a sealing member (33).

Therefore, the rotary drum 7 of the opening / closing device 4a is only supported by the attachment portion 6a with the rotational material with respect to the toilet seat 6, so that the toilet seat 6 is opened and closed. The poem only functions as a bearing.

However, when the toilet lid 5 is opened and closed, the attachment portion 5a is fixed to the rotary drum 7 so that the rotary drum 7 is around the shaft 9 according to the opening and closing operation of the toilet lid 5. Will rotate at. First, in the opening operation, the valve plates 24 and 23 are elongated grooves 19 and 19 because the blade paths 7b and 7b rotate counterclockwise in the state illustrated in FIG. 5 in the cylinder portions 25a and 25b. ) In the first valve piece (22, 22), swings on the second valve piece (20, 20) side and releases the paper to the long holes (15, 15). A passage of the viscous fluid 26 is formed through the two notches 24 and 24 and the first notches 21 and 21, and the viscous fluid 26 is formed from one cylinder portion 25a to the other cylinder portion 25b. And the other side of the cylinder portion 25b smoothly moves from one cylinder portion 25a to the other, the damper function does not work or exhibits only a very weak damper action, so the toilet lid 5 is opened without much resistance. . When the toilet lid 5 is closed, the valve plates 23 and 23 swing to the second valve pieces 22 and 22 in the opposite direction as shown in FIG. 5, and the valve plates 23 and 23 are closed. Since the long holes 15 and 15 are blocked, the flow of the viscous fluid 26 passes only through the arc grooves 18a and 18a, and the damper function is activated, so that the toilet lid 5 is quietly closed without falling down. The damper mechanism 16 has no ability to press the toilet lid 5 in the open direction, so that the closed lid 5 does not float in an open state.

Next, when the rotating drum 7 is overloaded due to a sudden opening / closing operation or the like, the arc of the partition wall 18 is suddenly pressed from one cylinder part to the other cylinder part by being pressed by the wing parts 7b and 7b. Each of the cylinder portions (slides through the grooves 18a and 18a by the viscous fluid 26 to slide against the elasticity of the compression spring 31 to the left in the state shown in FIG. In the fact that the volumes of 25a and 25b increase, the pressure of the viscous fluid 26 in each cylinder portion is weakened, thereby avoiding the destruction of the damper mechanism 16. In this way, when the overload is removed, the rotary drum 7 slides to the right by the elasticity of the compression spring 31, and returns to its original state.

FIG. 15 shows a moment curve when the toilet lid is opened and closed using the opening and closing apparatus 4a according to the present invention, and the toilet lid becomes self-supporting at an opening angle of 80 ° and is opened by pushing to 110 °. When the toilet lid is closed, it falls to 40 ° slightly faster in about 1 second at 80 ° independence, and then drops to 80 ° relatively slowly, requiring 2 seconds again.

10 to 14 show the internal structure of the opening and closing device 4b for the toilet seat 6 shown in FIG. 2, and most of the structures are opening and closing of the toilet lid 5 shown in FIG. It is similar to the apparatus 4a, but differs in that the cam mechanism 40 is provided. In particular, the cam structure 40 includes a pair of convex portions 41a and 41a provided with the shaft 42 fitted to one side of the partition wall 41 of the rotary drum 8, as shown in FIG. The shafts 42a and 43a provided in the slide member 43 which are non-rotating and slideable on the shaft 42 and the shaft 42 to press the slide member 43 toward the partition wall 41 side. The compression spring 45 is installed between the spring receiving member 44 fixed to the end of the shaft 42 and wound around the shaft 42, and the opening angle 80 is required for a stable independence of the toilet seat 6. At a temperature of 110 ° to 110 °, the convex portions 41a and 41a fall within the concave portions 43a and 43a of the slide member 43 attached to the shaft 42 so as to be non-rotating and sliding. To keep. The other structure and function are the same as the opening and closing device 4a for the toilet lid 5, and when the rotating drum 8 is overloaded, the rotating drum 8 slides slightly to the right in FIG. The damper mechanism 46 can be prevented from being damaged.

FIG. 16 shows a moment curve when opening and closing the toilet seat 6 using the switchgear 4b according to the present invention, and the toilet seat 6 becomes self-supporting at an angle of 80 ° and up to 110 °. It is opened, but the self-supporting state becomes very stable at the point which acquires the rotation suppression force which exceeds the torque by the cam mechanism 40. When the toilet seat seat 6 is closed, it falls to 40 ° a little more quickly in about 1 second in a state of independence of 80 °, and falls smoothly to 0 ° more slowly in 2 seconds.

[Effects of the Invention]
