Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a toilet seat opening device for opening a toilet seat of a western toilet and a western toilet having a toilet seat opening function.
[0002]
[Prior art]
When using a Western-style toilet for boys' small, it gets in the way so open the toilet seat.
However, since the operation of opening the toilet seat needs to bend down compared to the operation of closing, it is troublesome, so it is often performed in consideration of the person who will use it later. Among them, there is one that can easily open and close the toilet seat by driving and controlling the motor with a switch (Japanese Patent Laid-Open No. 62-44215), but there is a problem that it is expensive. In addition, since going to the toilet is usually in a hurry, there is also a frustrating problem if the switch must be operated each time to wait for the motor to rotate and the toilet seat to open.
[0003]
[Problems to be solved and means for achieving them]
Accordingly, the main object of the present invention is to provide an apparatus that can solve the above-mentioned problems by automatically opening the toilet seat after the toilet.
[0004]
Means for that purpose are urging means for urging the toilet seat in the opening direction, a follower rod attached to the toilet seat and moving as the toilet seat opens and closes, and a fixed state in which the toilet seat does not move relative to the toilet bowl. Sometimes the locking mechanism that locks the follower so that the toilet seat is not opened, and the toilet seat according to the urging force of the urging means by releasing the locking mechanism by turning the water flow lever that circulates water in the toilet. A toilet seat opening device having a lock release mechanism that opens the door.
[0005]
The transmission part of the lock release mechanism to the lock mechanism is constituted by a wire that is connected to the water flow lever and has a pulling action by the rotation of the water flow lever, or is provided at the rotation completion position corresponding portion of the water flow lever. The sensor means for detecting the completion of the rotation of the water flow lever and a solenoid driven based on the detection of the sensor means may be used.
[0006]
The urging means may be composed of a spring and / or a weight provided on the anti-toilet seat side of the driven rod.
[0007]
Another means is to provide a spring for urging the toilet seat in the opening direction, an action part for exerting the urging force of the spring, and a water flow lever for flowing water to the toilet, by operating the water flow lever. It is a Western-style toilet bowl connected with a link for driving.
[0008]
Further, a working rod extending in the vertical plane direction is fixed to the toilet seat, and a toggle mechanism is formed by the working rod to urge the toilet seat in both the opening and closing directions. The working lever includes a flow lever that allows water to flow into the toilet bowl. This is a Western-style toilet that is connected to a link that moves the working rod in the direction of opening the toilet seat until the dead center is exceeded.
[0009]
[Action and effect]
That is, according to the configuration of the toilet seat opening device described above, if the toilet is completed with the toilet seat closed (turned down), and the water flow lever is turned to flow the water, the unlocking mechanism is driven and attached to the toilet seat. The lock mechanism that locks the driven follower is released. Then, the toilet seat urged in the opening direction by the urging means is released by the urging force.
[0010]
As described above, the toilet seat is opened automatically by the turning of the water flow lever that is always performed after the toilet, and promptly by the urging force of the urging means. Much smoother than opening by rotating the motor.
[0011]
For this reason, it is not necessary to bend the waist and raise the toilet seat in a cramped posture as in the prior art, and it is convenient because it is released by the biasing means, so it is cheaper than using a motor, Moreover, the opening operation is quick.
[0012]
According to the second aspect of the present invention, since the transmission part of the unlocking mechanism is constituted by a wire, construction can be performed regardless of the positional relationship and distance between the water flow lever and the toilet as long as the wire is stretched. It ’s easy because it ’s just a stretch.
[0013]
According to the third aspect of the present invention, since the transmission part of the unlocking mechanism is constituted by the sensation means and the solenoid, no load is applied to the rotation of the water flow lever, and the operation can be performed lightly. Also in this case, as described above, the construction can be performed without any problem in the positional relationship between the water flow lever and the toilet.
[0014]
If the urging means is composed of only the spring and the weight or one of them as in the fourth aspect, the cost can be reduced. Further, if the spring and the weight are used together and the action of the weight is balanced so that the toilet seat is opened halfway, the spring constant of the spring to be used can be reduced. Thus, it is possible to suppress the momentum upon opening, seen to further close the toilet seat (defeat) the force is also small required when opening and closing operation is very rapidly done.
[0015]
According to the configuration of the above-described Western-style toilet, the toilet seat is urged in the opening direction, and the urging force can be exerted by operating the water flow lever. That is, in the Western-style toilet of Claim 5, the action part which exerts the urging | biasing force by a spring is driven by rotating a water flow lever, Moreover, in the Western-style toilet of Claim 6, a toilet seat is opened and closed both directions Since the action mechanism of the toggle mechanism that urges the lever moves in the direction of opening the toilet seat by moving the water flow lever until the dead center is exceeded, the toilet seat can be opened automatically by the flow of water that is always performed after the toilet. Can do. For this reason, it is not necessary to bend and bend tightly as in the past, which is convenient.
[0016]
In particular, when configured as in claim 6, in addition to the above effects, two advantageous effects are mainly obtained. In other words, the spring constituting a part of the toggle mechanism is urged not only in the toilet seat opening direction but also in the closing direction, so that it can maintain an open state and can exert an urging force even in a closed state. There is no backlash during use and a stable state of use is obtained. When the toilet seat is opened or closed by hand, the biasing force is applied when the dead center is exceeded, so that the opening / closing operation can be easily performed.
[0017]
【Example】
An embodiment of the present invention will be described in detail with reference to the drawings.
Figure 1 is a toilet with a toilet seat opening device 1 (hereinafter, referred toilet) indicates a water tank, toilet seat opening device, automatically seat 4 when the water flow in the rotation of the water flow lever 3 of the water tank 2 Is to be opened.
[0018]
The toilet seat 4 is urged in the opening direction, and a driven rod 5 that rotates as the toilet seat 4 opens and closes is integrally attached. One end of the driven rod 5 is fixed to the lower surface of the toilet seat 4, and the other end is parallel to the surface direction of the toilet seat 4 and extends in the horizontal direction opposite to the toilet seat 4. And the intermediate part is pivotally attached to the pivot support fixing member 6 integral with the toilet bowl main body 1a. The pivot support member 6 may be either formed in advance on the toilet body 1a or attached later.
[0019]
The pivot support member 6 pivotally supports and supports the follower rod 5 as described above, accommodates one of biasing means for biasing the toilet seat 4 in the opening direction, a spring 7, and further a lock mechanism. And a part of the unlocking mechanism.
[0020]
The spring 7 may be interposed in the pivotally attached portion of the toilet seat 4, but as described above, the toilet seat opening device is attached to the existing toilet 1 by inserting it into the pivot support member 6 that is separate from the toilet 1. It is good because it can be installed. In the figure, it is fixed to the toilet body 1a below the pivoting portion of the toilet seat 4. However, for example, it may be erected from the floor on which the toilet 1 is installed and positioned at a predetermined position. That is, it may be a fixed state that does not move relative to the toilet 1.
[0021]
The spring 7 may be attached as shown in FIG. That is, it comprises a spiral spring, the inner end 7 a is fixed to the rotating shaft 8 that pivotally supports the driven rod 5, and the outer other end 7 b is fixed to the inner surface of the pivot support member 6. At this time, it is set so as to be in the same state as when the follower 5 opens the toilet seat 4 as indicated by a virtual line. Since the distal end portion of the rotation shaft 8 does not rotate relative to the follower rod 5 as shown in FIG. 3, the vertical follower rod 5 as shown by the phantom line in FIG. When lying down, the spring 7 accumulates an urging force that returns to its original state. The reason why a large number of fixing portions 9 for fixing the other end 7 b of the spring 7 are provided as shown in the drawing is to enable the above setting and adjustment of the urging force by the spring 7.
[0022]
The locking mechanism locks the follower cage 5 to prevent the toilet seat 4 from being opened when the toilet seat 4 is in the closed state. As shown in FIG. 3, the locking claw has a locking claw 10 at the tip. The member 11 is configured to be biased by a compression coil 12 spring. The locking claw 10 of the locking claw member 11 is formed with an inclined surface 10 a on the upper side where the driven rod 5 falls and protrudes outside the pivot support member 6. The position is the position at which the lower surface of the follower 5 is received when the follower 5 is placed horizontally and the toilet seat 4 is closed (turned down) as shown by the solid line in FIG.
[0023]
The base of the locking claw 10 is formed obliquely, and the locking claw 10 is inserted through a block-shaped slider 13 having a long hole 13a that is long in the horizontal direction at the center.
[0024]
The slider 13 slides in the horizontal direction, and has an inclined inclined sliding surface 13b facing the inclined inclined sliding surface 11a of the base of the engaging claw 10, and the elongated hole 13a is engaged with the engaging hole. It is a slide groove to which the claw 10 moves relatively.
[0025]
Further, the tip end of the wire 14 that performs the pulling action is locked to the tip end of the slider 13. That is, the slider 13 is moved in the horizontal direction by the pulling action of the wire 14, and the engaging claw member 11 that is relatively moved by this movement retreats as shown by the imaginary line by the inclined sliding surfaces 11a and 13b inclined to each other. To do. Then, the locking claw 10 is flush with the pivot support member 6 or withdraws deeper than that. As a result, the driven rod 5 is released.
[0026]
When the pulling of the wire 14 is stopped, the compression coil spring 12 is elastically restored and pushes the locking claw member 11, and the inclined sliding surfaces 11 a and 13 b are rubbed against each other by this force, and the slider 13 is retracted and the locking claw 10 is moved back. Protrudes.
[0027]
The locking claw member 11 and the compression coil spring 12 constitute a lock mechanism, and the wire 14 and the slider 13 constitute a lock release mechanism.
[0028]
The lock release mechanism releases the lock mechanism by rotating the water flow lever 3, and the wire 14 for pulling the slider 13 has its base end fixed to the tip of the water flow lever 3. In FIG. 1, reference numeral 15 denotes a wire hose that slidably accommodates the wire 14. The water flow lever 3 side is fixed to the water storage tank 2, and the slider 13 side is fixed to the pivot support member 6.
[0029]
The follower rod 5 is provided with a weight 16 as one of urging means. The driven rod 5 extends straight ahead of the rotating shaft 8 in parallel with the toilet seat 4, and the weight 16 is attached to the tip thereof. This is because the force of the spring 7 that acts to raise (open) the toilet seat 4 is weakened to suppress the impact at the time of opening, and the force required to close the toilet seat 4 is reduced. For example, it is good to be able to balance in the position opened about 30 to 40 degrees. Opening and closing operations are performed very quickly. The attachment is performed by screwing screws as shown, and the male screw 5a formed on the driven rod 5 is preferably formed long. This is because the adjustment works.
[0030]
In the toilet seat opening device configured as described above, when the toilet is finished with the toilet seat 4 closed (tilted), and the water lever 3 is rotated to flow water, the wire 14 pulled by the water lever 3 is The slider 13 in the pivot support member 6 is pulled. Then, the latching claw 10 that locks the driven rod 5 attached to the toilet seat 4 is retracted, the driven rod 5 is released, and is biased in the opening direction by the biasing means of the spring 7 and the weight 16. The toilet seat 4 is opened by the biasing force.
[0031]
When the water flow lever 3 is released, the slider 13 is retracted and returned to the original state by the action of the compression coil spring 12 that pushes the locking claw member 11, and the locking claw 10 also protrudes as it is. When the toilet seat 4 is tilted (closed) in use, the driven hook 5 comes into contact with the protruding locking claw 10 from above, but since the upper side of the locking claw 10 is formed by the inclined surface 10a, the locking claw member Only 11 retreats to allow the driven rod 5 to pass, and when it passes, it protrudes as it is due to the action of the compression coil spring 12 and is locked to the upper surface of the driven rod 5 to prevent the driven rod 5 from returning.
[0032]
In this way, the toilet seat 4 is opened quickly and automatically by the rotation of the water flow lever 3 that is always performed after the toilet, and by the urging force of the urging means. Much smoother than opening by rotating the motor.
[0033]
For this reason, it is not necessary to bend the waist and raise the toilet seat in a cramped posture as in the prior art, and it is convenient because it is released by the biasing means, so it is cheaper than using a motor, Moreover, the opening operation is quick.
[0034]
In addition, since the unlocking transmission portion is constituted by the wire 14, the wire 14 can be constructed regardless of the positional relationship and distance between the water flow lever 3 and the toilet 1 as long as the wire 14 is stretched. So it is easy.
[0035]
FIG. 4 is a structural explanatory view showing another example, and the transmission part of the unlocking mechanism is constituted by a cesane means 17 and a solenoid 18. The sensor means 17 is provided at a portion corresponding to the rotation completion position of the water flow lever 3 and detects the completion of rotation of the water flow lever 3, and is constituted by, for example, a photoelectric sensor. You may comprise a limit switch. In the figure, it is provided only on one side of the “large” side, but may be provided on both sides of the “large” and “small” sides. The solenoid 18 is linearly driven based on the detection of the sensor means 17 and pulls the wire 14 locked to the tip of the slider 13.
[0036]
If comprised in this way, no load will be applied to rotation of the water flow lever 3 , and operation can be performed lightly. Also in this case, as described above, there is an advantage that the construction is possible without any problem in the positional relationship between the water flow lever 3 and the toilet 1.
[0037]
Another example will be described next.
FIG. 5 is a perspective view of the toilet 1. The toilet 1 has a toilet seat 4 and a toilet lid 19 pivotally attached to the back side of the upper surface of the toilet main body 1 a, and the toilet seat 4 is operated by operating the water flow lever 3 of the attached water storage tank 2. Is configured to open.
[0038]
That is, two pivoting portions 1b and 1b are provided on the left and right at the pivoting portion of the toilet body 1a, and the toilet seat 4 and the toilet lid 19 are held between the pivoting portions 1b and 1b. It can be rotated by passing 20. Then, the toilet seat 4 is urged in the opening direction through a torsion coil spring 21 at the pivotally attached portion of the toilet seat 4.
[0039]
Further, a cam 22 having a locking claw 22a on the outer peripheral surface which does not allow the toilet seat 4 to rotate in the opening direction is fixed to one end of the pivot shaft 20. The locking claw 22a is set to face upward when the toilet seat 4 is closed.
[0040]
When the toilet seat 4 is in a closed state, the locking claw 22a of the cam 22 is twisted so that the locking portion 23a at the tip of the swing arm 23 pivotally attached to the water storage tank 2 is engaged. The urging force of the coil spring 21 prevents the toilet seat 4 from opening. The swing arm 23 and the cam 22 correspond to the action portion in claim 5.
[0041]
The swing arm 23 is held by a guide member 24 fixed to the water storage tank 2 so as to move only in a vertical direction by a predetermined amount so that it does not swing sideways, and a portion on the tip side from the pivoting portion 23b is connected via a link 25. It is connected to the water flow lever 3, and the swinging arm 23 is lifted up by the turning operation of the water flow lever 3 to release the engagement between the locking portion 23 a and the locking claw 22 a of the cam 22. That is, when the water flow lever 3 is rotated as shown in FIG. 6, the swing arm 23 is lifted and disengaged by the link 25, the urging force is exerted, and the toilet seat 4 is opened.
[0042]
In the toilet 1 constructed in this way, after being used for a girl or boy's college, if the water flow lever 3 is operated to flush the water, the toilet seat 4 will automatically rise, and the human being will be used for the boy's next use. However, it is not necessary to open the toilet seat 4, which is convenient.
[0043]
If the drive amount of the link 25 due to the swing of the swing arm 23 is set to be smaller than the drive (rotation) amount necessary for the water flow lever 3 to flow water, The toilet seat 4 can be opened without flowing water.
[0044]
7 is a perspective view of the toilet 1 and FIG. 8 is a side view. In the toilet 1, the toilet seat 4 is automatically opened and closed using a toggle mechanism.
[0045]
In other words, an L-shaped working rod 26 extending upward is fixed to the vicinity of the pivotally attached portion of the toilet seat 4, and the toggle mechanism is configured by the working rod 26. One end of a tension coil spring 27 is rotatably fixed to the upper end of the working rod 26, and the other end of the tension coil spring 27 is rotatably fixed to the toilet body 1a. The toilet seat 4 is shown in FIG. As described above, when opened obliquely, the working rod 26 is inclined so that the dead center where the tension coil spring 27 extends most is reached. The toilet seat 4 is urged in the opening direction on the opening side from the dead center and in the closing direction on the closing side.
[0046]
As a means for driving the toggle mechanism, a link 28 is connected to move the working rod 26 in the opening direction of the toilet seat 4 until the dead point is exceeded by turning the water flow lever 3. The link 28 has an operating rod 29 that is pivotally attached at one end to the water flow lever 3, and a swing rod 30 that is pivotally fixed to the end of the operating rod 29 and is pivotally supported by the tank 2. And a pulling rod 31 that pulls the working rod 29 downward by the swinging of the swinging rod 30. A long hole 31a is formed in the traction rod 31 so that the upper end of the working rod 26 slides.
[0047]
If the amount of driving (turning) of the water flow lever 3 by driving the action rod 26 is set smaller than the amount of driving required for the water flow lever 3 to flow water, that is, the pivot point 30a of the swing rod 30 is set. When the driving amount of the swinging rod 30 is amplified by moving toward the base end side (operation rod 29 side), water does not flow even if the toilet seat 4 is opened by hand.
[0048]
In the toilet 1 configured as described above, as in the case of the previous embodiment, when water is flowed, the operating rod 29 is pulled up and the tip of the swinging rod 30 is pushed down. When the pulling rod 31 is pulled by the pulling rod 31 and the dead center is exceeded, the toilet seat 4 is rotated in the opening direction by the pulling coil spring 27, and the upper end of the loading rod 26 slides down the long hole 31a of the pulling rod 31 downward. As a result, the toilet seat 4 is opened. In other words, the toilet seat automatically rises, and it is not necessary for the person to open the toilet seat for the next boys' use, which is convenient.
[0049]
In addition, since the tension coil spring 27 is biased not only in the opening direction of the toilet seat 4 but also in the closing direction, the tension coil spring 27 can maintain the open state and can exert the biasing force even in the closed state. Stable use is obtained without sticking. Further, when the toilet seat 4 is opened or closed by hand, an urging force acts if the dead center is exceeded, so that the opening / closing operation can be easily performed.
