Below, with reference to Fig. 6 the action of first rotary component 9 that constitutes as stated, be connected with toilet cover is described.
What Fig. 6 (1) represented is the rotational position of first rotary component 9 of toilet cover full open position.What this rotational position was represented is first rotary component 9 reaches situation from the terminal area of a direction to counterclockwise direction (direction of arrow B) rotation; In this terminal area, the state that the opening action of toilet cover is stopped fully through not shown outside brake member.
What Fig. 6 (2) represented is the rotational position of toilet cover from fully open position to first rotary component 9 that is closed to half the state.This rotational position is represented be first rotary component 9 from the rotational position shown in Fig. 6 (1) along clockwise direction (direction of arrow A) begin rotation, the angle of rotation of its rotating distance is about 40 ° state.From Fig. 6 (1) to the rotating distance Fig. 6 (2) because first rotary component 9 is the roughly state rotation down of standard-sized sheet at the opening of the fluid passage 36 between a of pressurized chamber, a ' and underpressure chamber b, the b ', thereby rotate reposefully with can not producing high torque (HT).Therefore, toilet cover can be closed from the rotation initial stage reposefully.
What Fig. 6 (3) represented is the rotational position that toilet cover is closed to first rotary component 9 of the state about 2/3.What this rotational position was represented is that first rotary component 9 further rotates to the opposing party's terminal area from the rotational position shown in Fig. 6 (2) along clockwise direction, and the angle of rotation of rotating distance is about 60 ° state.Even from Fig. 6 (2) to the rotating distance Fig. 6 (3) because the opening of the fluid passage 36 between a of pressurized chamber, a ' and underpressure chamber b, the b ' opens always, thereby first rotary component 9 does not produce high torque (HT) ground and rotates.Therefore, toilet cover is closed reposefully.
But; In the state shown in Fig. 6 (3); The front-end face 32 of protruding wall 31 that arrives the first fluid locellus 7 of shells 2 owing to the opening 38 of the another side of fluid passage 36 is closed, thereby the fluid passage 36 between a of pressurized chamber, a ' and underpressure chamber b, the b ' is closed fully.Therefore, the increased pressure of a of pressurized chamber, a ' and produce high torque (HT).Therefore, to toilet cover effect damping force.
What Fig. 6 (4) represented is the rotational position of first rotary component 9 of toilet cover buttoned-up status.What this rotational position was represented is that first rotary component 9 further is rotated in a clockwise direction from the terminal area shown in Fig. 6 (3), in this terminal area, and the state that the closing motion of toilet cover is stopped fully through not shown outside brake member.Therefore, toilet cover is closed fully.
Rotating distance from Fig. 6 (3) to the terminal area Fig. 6 (4); Because a of pressurized chamber, a ' are in complete closing state with fluid passage 36 between underpressure chamber b, the b ', a of pressurized chamber, a ' keep under the state of high pressure to first rotary component, 9 generation damping functions be rotated.Therefore, because the effect of damping force is closed toilet cover at leisure.
In addition; First rotary component 9 begins rotation and when opening toilet cover to counterclockwise direction again from position that the toilet cover shown in Fig. 6 (4) is closed fully; Owing to open at leisure a of pressurized chamber, a ' and the underpressure chamber b that close at the rotation initial stage, the fluid passage 36 between the b ', thereby first rotary component 9 is except that the rotation initial stage, not producing the rotation of high torque (HT) ground.Therefore, toilet cover when beginning to open from can both open reposefully with little power.
Below, with reference to 7 pairs in accompanying drawing as stated the action of second rotary component 10 that constitute, that be connected with toilet seat describe.
As stated, the fluid passage 39 of second rotary component 10 is except the fluid passage of the part that connects base portion and first rotary component 9 36 is different, and all the other have essentially identical shape.Therefore the action of second rotary component 10 is identical with the action of first rotary component 9 basically.
That is,, be in the state that the opening action of toilet seat stops fully at the rotational position of second rotary component 10 shown in Fig. 7 (1).Under the state that toilet seat fully open position, opening action stop, because opening, the opening of the fluid passage 39 of the connection a of pressurized chamber, a ' and underpressure chamber b, b ' communicating, thus the zone of formation low torque.
Be closed to the expression toilet seat the rotating distance Fig. 7 (2) of half the state from the fully open position of Fig. 7 (1); Because second rotary component 10 roughly rotates under the state of standard-sized sheet at the opening of the fluid passage 39 between a of pressurized chamber, a ' and underpressure chamber b, the b '; Thereby, rotation reposefully under the state that does not produce high torque (HT).Therefore, toilet seat began promptly to close reposefully from the rotation initial stage.
Even the rotating distance the Fig. 7 (3) that is closed to the state about 2/3 from Fig. 7 (2) to the expression toilet seat; Because the opening of the fluid passage 39 between a of pressurized chamber, a ' and underpressure chamber b, the b ' is still opened, the still rotation under the state that does not produce high torque (HT) of second rotary component 10.Therefore, toilet seat is closed reposefully.
But under the state shown in Fig. 7 (3), the front-end face 32 of protruding wall 31 that arrives the second fluid locellus 8 of shells 2 owing to another opening 41 of fluid passage 39 is closed, the increased pressure of a of pressurized chamber, a ' and produce high torque (HT).Therefore, toilet seat receives the effect of damping force.
