Description of the Related Art In a drainage device in which the flushing operation of a flush toilet is performed after the flushing of a toilet bowl is confirmed and then a drainage valve opening / closing lever or knob of a water storage tank is returned to its original state, The user must continue the draining operation throughout the washing, and must bear the troublesome work. It is preferable from the standpoint of operation and hygiene that the washing operation is completed by automatically draining the water in the water storage tank at once if the lever is manually operated only once. However, performing flushing with the same amount of water for both defecation and urination is not preferable in terms of saving water.

動角αを使い分け、節水を図ることができる。Therefore, in the drainage device 100 shown in FIG. 8, when the cam 103 is turned by a required angle by operating the set knob 102 of the timer means 101, the cam 103 turns one side of the operation arm 104 in the downward direction. Then, the drain valve 106 is opened via the connecting rod 105 suspended from the tip of the opposite arm to start draining. When the lever 102 is released, the cam 103 gradually returns to the initial position from the set rotation angle α by the driving of the timer means 101. Then, the operating arm 104 descends, and the drain port 107 is closed by the drain valve 106 via the connecting rod 105 to stop draining.
In this case, since the amount of drainage can be controlled by the magnitude of the turning angle of the lever 102, the turning angle α of the lever 102 can be properly used according to the size of the service, thereby saving water.

Depending on whether the rotating operation of the operation lever 201 is rotated clockwise R or counterclockwise L from the neutral position in the drawing, the amount of drainage for stool and the amount of drainage for urine can be selectively used. I have. That is, the rotation shaft 202 extends horizontally coaxially with the operation lever 201, and the drain valve 20
3 is formed directly above the operating arm 204 that changes its direction.
Since the tip 205 of 4 rotates upward from the hanging position, the chain 206 connected to the tip 205 raises the drain valve 203 to drain water. When the operating lever 201 is released, the distal end 205 of the operating arm returns to the initial hanging position, and the drain valve 203 closes the drain port 207.

8 rotate together and are hooked on the hook 209 to restrict the return operation. A pulley 210 is attached to the rotating shaft 202.
Is also fixed, the timer lever 212 connected by the belt 211 is turned counterclockwise in conjunction with the rotation of the pulley 210. The timer lever 212 slowly returns to the illustrated initial position at a speed controlled by the timer 213, pushes the opposite end 214 of the hook 209 to rotate the hook 209, and releases the locking lever 208. Therefore, the operating arm 204 freely hangs down and the drain valve 203

The amount of drainage is controlled by the time required to return to the initial position at the speed controlled by the timer means from the rotation angle α set on the cam 103. However, it is troublesome to set a proper setting on one of the large and small stools every time it is used, and if it is not proper, it may be unsanitary or may not fulfill the purpose of saving water. Further, an arm 104 interlocked with the returning operation of the cam 103 controlled by the timer means.
Movement is slow and the drain is gradually closed,
A large load is applied to the arm 104 due to the rapid action of drawing the water flow into the drain valve 106. For this reason, the material strength and durability of the device itself become problems.

Since the operation direction 01 corresponds to large and small stools, the trouble of setting the rotation angle to an appropriate position is released. Further, the operation of the drain valve after the lock is released is rapidly performed. However, when the rotation direction of the shaft is different depending on the size of the service, a large difference may occur in the stroke for lifting the drain valve 203 depending on the positional relationship between the drain port and the operation arm 204, which may make it impossible to respond.

Accordingly, the end surface 88 of the stopper 86 that has turned toward the hook portion 84 (counterclockwise in the drawing) from the direction of the fixed shaft 78 at the center of rotation of the holding member 76 abuts the locking surface 90 of the hook portion 84. As a result, the rotation is prevented and the position is maintained. In the initial position shown in FIG. 1, the distal end of the action piece 80 is pushed by the release member 94, the holding member 76 is rotated, the hook portion 84 is positioned outside the rotation path of the stopper 86, and the stopper 86 Does not interfere with

When the stopper 86 slides on the outer surface 92, the hook portion 84 resists the urging force. Can be pushed out of the rotation path and can be freely swung. Also, the end surface 88 of the stopper 86
Is held in a hooked state by contacting the locking surface 90 of the hook portion 84, the action piece 80 of the holding member 76 is pushed by the release member 94 connected to the boss 82 of the interlocking gear 64. And the hook portion 84 has a stopper 86 against the urging force.
The stopper 86 is released from the rotation path, and the stopper 86 is unlocked and can freely rotate.

It is interposed between the two inner walls and is pivotally supported by well-known bearing means having very little rotational friction. A gear 56-1 is connected to the same shaft as the speed adjusting pinion 56 driven by the interlocking gear 64 via a known one-way clutch 59, and meshes with the next pinion 56-2.

The gear 56-5, which is coaxial with the gear, meshes with the next pinion 56-6. In the final stage worm speed increasing gear mechanism 60, a worm gear 56-7 that meshes with a worm 62-2 formed directly on a shaft 62-1 of the governing governor 62 is coaxial with the pinion 56-6 to rotate integrally. Finally, the governing governor 62 is rotated at a high speed, the air resistance is amplified and transmitted to the interlocking gear 64, and the restoring force by the torsion spring 66 is controlled.
As a result, the interlocking gear 64 receives a deceleration action, and exhibits a delayed operation of returning to the initial position over time.

ピニオン５６との噛合が外れる。By the way, the rotation of the operation shaft 16 pushes the projection 74 to the outer peripheral projection 68, and the interlocking gear 64 is rotated by about 90 °.
Although the gear portion of the interlocking gear 64 is rotated, the gear portion of the interlocking gear 64 is less than 90 °, and the toothless portion is provided shortly before the end of the rotation. Therefore, when the interlocking gear 64 has completed the predetermined rotation, the speed adjusting pinion 56 Is disengaged.

噛合に入る。Accordingly, in the initial movement stage in which the interlocking gear 64 is released from the rotation of the operation shaft 16 and is rotated in the return direction under the control of the own weight of the operation arm 18 and the restoring force of the torsion spring 66, the speed control is performed. Since it is not meshed with the pinion 56, the restoring force of the torsion spring 66 is transmitted to the interlocking gear 64 without any resistance and starts the interlocking gear 64 strongly, and the outer peripheral surface of the cam 65 slides against the recess 57-1 while resisting. If it rotates without rotating, the interlocking gear 64 enters into engagement with the governing pinion 56.

With the strong initial motion due to the missing tooth portion, the timer means 55 can be started by overcoming the static friction resistance and the inertial resistance of the speed increasing gear train 58 in the stationary state.

Since the resistance from 2 is continuously received, as described above,
The interlocking gear 64 returns to the initial position at a speed controlled by the timer means 55.

FIG. 4 illustrates a state in which the operation lever 12 is manually operated to rotate the operation shaft 16 clockwise by about 90 °. At this time, in the first operating member, the pressing surface 42 of the projection 40 provided on the first gear 30 integrated with the operation shaft 16 abuts on the passive surface 46 of the projection 44 of the second gear 36 so that the second gear 36 is the same. Forcibly rotate about 90 ° clockwise. At this time, the stopper 86 of the second gear contacts the outer surface 92 of the holding member hook portion 84 and pushes the hook portion 84 outward as described above, so that the holding member 76 does not receive interference.

Because of the forcing, the torsion spring 66 is wound in the direction of the force. The speed adjusting pinion 56 meshing with the interlocking gear 64 rotates together, but this rotation is not transmitted to the speed increasing gear train 58 by the action of the one-way clutch 59. Therefore, the operation axis 1
No braking force is generated by the governing governor 62 for the operation of rotating the motor 6 approximately 90 degrees clockwise.

By the rotation of 0, the fourth gear 38, which is another gear meshing with the sector gear 20, is rotated clockwise by about 90 °. Then, the third gear 34 meshing with the first gear 30 is rotated approximately 90 ° counterclockwise. That is, the third gear 3
The projection 48 of the fourth gear and the projection 52 of the fourth gear 38 rotate freely in the separating direction without interfering with each other.

The state where the operating shaft 16 that has been released is returned to the initial position by the torsion spring 26 is illustrated. The third gear 34 meshed with the first gear 30 integrated with the operation shaft 16 also returns to the initial position. Further, since the pressing surface 70 of the outer peripheral projection 68 of the first gear is separated from the passive surface 72 of the projection 74 of the interlock gear 64, the interlock gear 64 that has lost support is governed by the restoring force of the torsion spring 66.

However, the end face 88 of the stopper of the second gear 36 meshing with the sector gear 20 is engaged with the locking surface 90 of the holding member hook portion 84, so that the rotation of the second gear 36 is prevented. For this reason,
The lowering of the operating arm 18 stops and is held at that position.

From the moment when the gear is released, the interlocking gear 64 rotates counterclockwise by receiving the restoring force of the torsion spring 66, but the rotation of the meshing governing pinion 56 is the rotation transmitting direction of the one-way clutch 59. The power is transmitted to the governing governor 62 via the speed increasing gear train 58, and the rotation speed is limited. Therefore, the return of the interlocking gear 64 to the initial position is performed by the operation lever 1.
Achieved with a delay from the point at which 2 is operated. This delay time corresponds to the amount of water necessary for cleaning the toilet tank (not shown).

Release the end face 88 of the gear stop. Therefore, the second gear 36 can freely rotate, and the meshing sector gear 2
At 0, the operation arm 18 held at the upper position freely descends to the initial position. As a result, the drain valve is closed, and the outflow of the washing water from the water storage tank is stopped.

0 moves away from the projection 48 of the second gear,
The first gear 30 is the third gear 3 of the meshed second operating member.
4 is rotated approximately 90 ° clockwise. Thus, the third gear 34 forces the pushing surface 50 of the projection 48 into contact with the passive surface 54 of the projection 52 of the fourth gear, forcing the fourth gear 38 to rotate about 90 ° in the same clockwise direction. .

Since the projection is rotated by about 90 ° in the direction, the projection 40 of the first gear and the projection 48 of the second gear can rotate without interfering with each other.

It can rotate freely in conjunction with the operation arm 18. That is,
The operation arm 18 immediately responds to the movement of the operation lever 12, and the delay mechanism by the timer means 55 does not function. For this reason, the drain valve can be opened and closed in response to the flush state of the toilet tub, which is suitable for urine cleaning.

The same members as those in the first embodiment are denoted by the same reference numerals. As means for forming such a mirror image relationship, the positions of the first operating member, the timer means 55, and the fixed shaft 78 of the holding member of the delay drive device 10 of the first embodiment are turned by 180 ° and positioned. At this time, the pressing surface 4 of the projection 40 of the first gear 4
3 is on the opposite side of the pushing surface 42, and the projection 44 of the second gear
The passive surface 47 is rearranged so as to be on the opposite side of the passive surface 46, and is arranged so that the pushing surface 43 and the passive surface 47 abut.

At this time, the pushing surfaces 51 of the projections 48 of the third gear are on the opposite side of the pushing surfaces 50, and the passive surfaces 53 of the projections 52 of the fourth gear are on the opposite side of the passive surfaces 54. The positions are rearranged, and the pressing surface 51 and the passive surface 53 are placed in contact with each other.

る。The sector gear 20 is composed of the second gear 36 and the fourth gear 3
The operating arm 18 is arranged so as to mesh with both of the operating arms 8 and 8 so that the operating range becomes a mirror image relationship. Here, the contact relationship between the pressing surface 70 of the outer peripheral projection 68 of the first gear and the passive surface 72 of the projection 74 provided continuously with the interlocking gear 64 does not change.
The relationship between the rotation direction and the action on the timer means 55 is the same. Therefore, the operating lever 12 is turned clockwise about 90 degrees.
By rotating the torsion spring 66, the torsion spring 66 is entangled in the direction of the force, and the timer means 55 is shifted to the set state.

る。When the operation lever 12 is rotated clockwise,
Since the first gear 30 rotates the third gear 34 in the counterclockwise direction, the fourth gear 38 is rotated by the passive surface 53 which is brought into contact with and interlocks with the pushing surface 51 of the projection 48 of the third gear to form a sector shape. Gear 2
0 turns the operating arm 18 clockwise. The rotation of the sector gear 20 causes the second gear 36 to rotate counterclockwise, so that the projection 44 is separated from the projection 40 of the first gear. That is, in the reverse mounting structure, the clockwise rotation of the operation lever 12 causes the second operation member to act on the operation arm 18.

面として係止面９１を形成する。At this time, the stopper 87 integrated with the second gear 36 has shifted to the left side in the figure from the locking surface 91 of the holding member 77. Therefore, when the operating lever 12 is returned to the initial position shown in FIG. 7, the second gear 36, which is clockwise rotated by the lowering of the operating arm 18 due to its own weight and the restoring force of the torsion spring 66, is a stopper end face provided integrally. The rotation of the holding member 89 is stopped by abutting the locking surface 91 of the holding member. For this reason, the operation arm 18 stops during the descent and is held as it is. Since this blocking action acts in the direction of the fixed shaft 78, the hook portion of the holding member 77 changes its shape, and the outer surface 92 of the holding member 76 is formed as a plane facing the stopper end surface 89 to form the locking surface 91.

Those skilled in the art will fully understand from the drawings that it is possible to cope with reverse mounting only by changing the shape of the first gear and the meshing position of the gears of the first gear and the second gear. Also, it goes without saying that a commonly usable housing can be applied as long as a suitable space is allowed. Other operations and functions of the respective members are the same as those in the first embodiment, and thus description thereof will be omitted.

響されることなく対応することができる。As described above, according to the delay actuating device according to the present invention, it is possible to selectively use washing corresponding to large and small stools depending on the rotation direction of the operation lever, so that it is troublesome to wash the toilet. It can be carried out without any problems and can improve the water saving effect as well as the sanitary effect. Further, since there is no difference in the stroke of the operation arm depending on the rotation direction of the operation lever, the mounting of the device can be performed without being affected by the distance to the drain port.

影響は少なく、作動アームにかかる負荷が小さくなる。In the case of stool washing, the operation arm is automatically held for a fixed time during drainage, so that the amount of water flowing out from the drainage port is stabilized. On the other hand, since the water valve rapidly returns to the initial drain valve closing position, the influence of the dynamic pressure of the water flow on the drain valve is small, and the load on the operating arm is reduced.

省力化できる。Further, since the reverse mounting configuration is made possible by simply changing the combination of almost the same mechanical components as they are, the number of components that vary depending on the model corresponding to the mounting position is reduced, and component stock and component management are reduced. Can save labor.
