Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to improvement of a seat sheet automatic feeding toilet seat.

[Conventional technology]

In recent years, when using a Western-style toilet seat, as a device for laying sheet paper on the toilet seat in consideration of its hygiene, for example, the actual open sho
There is a toilet seat cover supply device described in Japanese Patent Publication No. 155399.

The device is shaped and sized so that it can cover the upper surface of the toilet seat body, and it is wound into a continuous sheet paper roll and accommodated in a protective cover. A paper holder that supports the sheet paper roll so that it can be continuously drawn out,
A feeding roller device for feeding the sheet paper fed from the sheet paper roll forward by a predetermined length near the upper surface of the toilet seat body, and cutting the rear end of the sheet paper fed by the predetermined amount on the toilet seat body. And a cutting device having a cutting blade.

In such a conventional device, for feeding and cutting the sheet paper, the operation switch is turned on to start the electric motor,
After the sheet paper is fed by the feeding roller device to a length covering the toilet seat body, a cutting device including a movable blade and a fixed blade is driven by another electric motor to cut one sheet of sheet paper. As described above, when using the western-style toilet bowl, since the sheet paper can be automatically laid on the toilet seat body and seated, the user can hygienically utilize the western-style toilet bowl.

[Problems to be solved by the device]

However, in the toilet seat cover supply device having the above configuration,
There were the following problems.

(1) Generally, the toilet seat body is mounted on a Western-style toilet in a freely openable and closable manner by attaching it to a casing containing a feeding roller device and a cutting device for rewinding a sheet paper roll by using a pivot shaft. As a result, if the user accidentally sits on the toilet seat body with excessive force when seated, not only will the position of the fed sheet paper be displaced, but also a large load will be applied to the pivot shaft causing it to break or distort. Alternatively, there is a problem in that the toilet seat body may be deformed and the opening / closing operation of the toilet seat body cannot be performed smoothly.

(2) In addition, the sheet paper unwound from the sheet paper roll and fed out onto the toilet seat body is merely mounted on the toilet seat body after being cut by the cutting device. When the user tries to sit on the toilet seat body, the seat paper may slip or slip off on the toilet seat body as described above unless the seat is carefully seated. Furthermore, when leaving the seat after finishing sitting, if the sheet paper is not held on the toilet seat body by some holding means, when standing up from the toilet seat body,
There is a problem in that the sheet paper is caught around the buttocks of the user, which gives the user discomfort.

SUMMARY OF THE INVENTION In view of the above problems, the present invention buffer-supports a pivot shaft that pivotally supports a toilet seat body, buffers various loads applied to the pivot shaft, and damages the pivot support portion of the toilet seat body. The seat sheet automatic feed toilet seat is designed to prevent the user from grabbing the seat paper when the seat paper laid on the toilet seat body is separated by slowing down the return operation of the lowered toilet seat body to its original position. The purpose is to provide.

[Means for Solving the Problems]

According to the present invention, a casing that accommodates and installs a mechanism portion composed of a paper feeding mechanism and a paper cutting mechanism is arranged on the rear side of the toilet body, and the toilet seat body can be opened and closed on the toilet body in the casing, and In addition to vertically pivoting, when the user sits on the toilet seat main body, the seating operation is buffered to the descending operation of the toilet seat main body and the paper cutting and pinching operation of the paper cutting mechanism. And a cushioning device that delays the paper-holding time in the paper cutting mechanism when the seat is released from the toilet seat body. To do.

[Action]

The present invention is provided with a shock absorber for seating on the toilet seat body so that the pivotal support portion of the toilet seat body cushions the descending motion of the seat cushion to promptly perform the descending motion, and conversely, when the seat is rising, gently raises the seat. Therefore, even if the user is strongly seated on the toilet seat body, it is possible to prevent damage to the pivotal support portion of the toilet seat body by being buffered by the cushioning device. When the user separates from the seat cushion and the load applied to the toilet seat body is released, the pivot support portion of the toilet seat body is gently returned to the original position (elevation) side. Even if the user separates from the toilet seat body, the sheet paper that is being fed out is held in the sandwiched state by the paper clamping mechanism by the paper cutting mechanism for a while. Characterized in that negative effects were to be reliably eliminated.

As shown in FIG. 10, longitudinally elongated guide grooves 11b, 11b are bored in the inner side walls 11a, 11a of the pivot shaft 6 attached to the rear left and right sides of the toilet seat body 5 in the guide grooves 11b, 11b. , 6a are inserted rotatably in the lateral direction and vertically movable. The pivots 6 and 6a are rotatably supported by box-shaped movable bearings 13 and 13 that are fitted in the lifting guide boxes 12 and 12 formed in the pivotal support sections 11 and 11 so as to be able to move up and down, and It is inserted so that it cannot be pulled out, and it is normally urged upward by a shock absorber 14,14 described later, and further upward movement is restricted by a restriction plate 15 attached to the upper end surface of the elevating guide boxes 12,12. Therefore, the normal time (when not sitting on the toilet seat body 5) is
As shown in FIG. 10, the toilet seat body 5 is held at the uppermost position and is maintained in a front low rear high inclination state as shown in FIG. It is held so that it can be opened and closed centering around 6a and can be moved up and down.

Then, the shock absorber 14 is, as shown in FIG. 11, a cylinder 14a, a piston 14b inserted in the cylinder 14a so as to be able to move up and down, and a piston rod 14c is inserted between the piston 14b and one side thereof.

On the other hand, as shown in FIGS. 3 and 4, the shaft rod 41 on which the cam member 42 is supported includes the pivot shafts 6 and 6a for pivotally supporting the toilet seat body 5 on the pivot portions 11, 11 and the operating lever 4.
When the user sits on the toilet seat body 5, the rear portion of the toilet seat body 5 descends against the biasing force of the shock absorber 14, as shown by the alternate long and short dash line in FIG. The shaft rod 41 is rotated by the operating lever 43 to operate the paper cutting mechanism 9.

In FIGS. 3 and 4, reference numeral 44 designates a space in which the paper holding members 35, 35a can be retracted into and out of the paper delivery path 32 on the installation space a of the inclined ceiling wall 17a into which the storage frame 33 is fitted. The remaining paper guide plate, 45 is the machine frame of the suspension frame 30

Next, a schematic configuration of the control device 21 that controls the operations of the paper feeding mechanism 8, the sensor, and the detecting means will be described.

In FIG. 14, the control device 21 is a microprocessor MP.
U and a paper position detection sensor 51 (see FIG. 4) that detects the through hole 50 for position detection provided at each position where the sheet paper P extends to cover the toilet seat body 5 and produces an output,
Paper feeding switch 52 provided on the operating portion of the casing 7
(See FIG. 1), an input interface 54 connected to control output generating means such as the seating detection means 53, an output interface 55 connected to the paper feeding mechanism 8, and a program for feeding / stopping the sheet paper P are stored. Memory 56
And a timer 57, and a drive circuit 58 inserted between the output interface 55 and the paper feeding mechanism 8 and a power supply circuit 59 connected to the drive circuit 58.

Then, the paper position detection sensor 51 is, for example, a combination of a phototransistor and a photodiode, is attached to the machine casing 29 inside the paper delivery port 46, and on the inclined ceiling wall 17a side corresponding to the attachment position, Sensor 51
The passage opening 60 for passing the light of is penetrated.

Further, as shown in FIG. 13, the sheet paper P is provided with a perforation 61 which is close to the through hole 50 and serves as a boundary of the first sheet of the sheet paper P, and the toilet seat body 5 is provided at the center of the sheet. A punching tongue piece 62 is provided with a part left uncut corresponding to the opening 5a.

The upper casing 7b is detachably fitted and connected to the upper edge of the lower casing 7a described above, and the paper holders 31, 31
The sheet paper roll R which is laid horizontally is formed into a storage portion, and the upper edge of the paper feeding port 46 is bent in a U shape on the front side thereof as shown in FIG. 63 is formed.

Next, the operation will be described.

At the time of feeding the sheet paper P, the paper feeding switch 52 is pushed to drive the electric motor 20 by the battery power source 22. When the electric motor 20 is driven, the delivery roll 23 is decelerated and rotated via the reduction gear 25, and the sheet paper P sandwiched between the pressure roll 24 and the sheet roll R is rewound from the sheet delivery roll 32 → paper delivery port 46. When the sheet paper P is extended to the toilet seat body 5 and the sheet paper P substantially covers the toilet seat body 5, that is, the sheet paper P corresponding to the length of one sheet is extended, the position detecting through hole 50 is formed. Reaches the position of the paper position detection sensor 51 and is detected by the sensor 51, the detection signal is sent to the control device 21, and the stop signal programmed in the microprocessor MPU is sent from the control device by this signal. To stop the electric motor 20. Therefore, the paper feeding mechanism 8 stops the feeding of the sheet paper P. At this time, the perforation 61 of the sheet paper P is set to be located between the paper holding members 35, 35a of the paper cutting mechanism 9.

Next, a case where the sheet paper P fed onto the toilet seat body 5 is separated from the sheet paper roll R will be described.

When the user sits on the toilet seat body 5, as shown in FIGS. 5 and 6, the rear portion of the toilet seat body 5 resists the urging force of the shock absorbers 14, 14 provided on the lifting guide boxes 12, 12. It descends and operates the paper cutting mechanism 9. That is, in FIG.
As shown in FIG. 10, the pivots 6, 6a descend along the guide grooves 11b, 11b of the inner side wall 11a of the lower casing 7a and the guide grooves 16, 16 of the elevating guide boxes 12, 12. When the pivots 6, 6a descend, the piston rods 14c of the shock absorbers 14, 14 move the movable bearings 13, 1
Go down through 3. As the piston rod 14c descends, the piston 14b moves to the state shown in FIG.
The silicone oil 14h is allowed to flow into the upper surface side of the piston 14b through the flow holes (the check valve 14e is opened) 14d, 14f to drop in the cylinder 14a against the force of the compression spring 14g. At this time, the piston 14b is lowered by two large and small flow holes 14d and 14f.
Since it is fully opened, the impact load generated when the user sits on the toilet seat body 5 with a high force is due to the silicon oil 14h and compression generated when the piston 14b descends in the cylinder 14a. Since it can be buffered by the resistance force of the spring 14g, the pivots 6 and 6a of the pivots 11 and 11 are not damaged and the toilet seat body 5 is not deformed at all, and the toilet seat body 5 can be smoothly moved. It can be lowered. As described above, depending on the weight of the user, at the same time as the toilet seat body 5, the actuating lever 43 also descends on the pivot shaft 6, 6a side with the shaft rod 41 side as a fulcrum. When the operating lever 43 descends to the point t ₁ of the pivot 6 in FIG. 4, the shaft rod 41 fixing the fulcrum side of the operating lever 43 rotates counterclockwise in FIG. The engagement roller of the slide member 17 engaged with the cam groove d shown in FIG. 1 by rotating the cam member 42 supported on the rod 41 in the same direction by an angle corresponding to the amount by which the operating lever 43 is lowered.
39 is moved to the second cam groove e as shown in FIG. When the engagement roller 39 is pushed up by the rotation of the cam member 42 and moves to the cam groove e in FIG. 2, the slide member 17 moves in the upper movement range of the engagement roller 39 together with the storage frame 33 and the installation space a. As shown in FIG. 5, the sheet paper P pushed inside the paper delivery path 32 is pushed toward the paper delivery path 32 as shown in FIG.
The paper holding members 35 and 35a protruding into the inside 32, and the lower end surface of the machine frame 29 provided at the lower end of the suspension machine frame 30 corresponding to the paper holding members 35 and 35a and the projection 36a of the swing plate 36 Sandwich between. Then, the toilet seat body 5 is further lowered, and the operating lever
When 43 descends to the point t ₂ of the pivot 6 in FIG. 4,
As the actuating lever 43 descends to the point t _{2 of the} pivot 6,
The cam member 42 supported on the shaft rod 41 is further rotated by an angle corresponding to the amount by which the operating lever 43 is lowered. Therefore slide member
From the position shown in FIG. 5 to the spring 17, as shown in FIG.
It resists the force of 34 and linearly slides along the storage frame 33 toward the paper delivery port 46 side through the engagement roller 39. As the slide member 17 slides, the paper holding member 35 provided on the slide member 17 abuts via the projection 36a sheet paper P of the swing plate 36, so that the swing plate 36 and the pivot 36b are connected to each other. As the center, it is rotated clockwise in FIG. On the other hand, although the storage frame 33 is rotated by the cam member 42, the storage frame 33 is hung through the slide member 17 to suspend the frame.
Since the sliding member 17 is biased toward the machine frame 29 side of the 30, that is, the slide member 17 rotates the cam member 42 within a range in which the pressing of the storage frame body 33 is not released, and thus the storage frame body 33 side. The paper holding member 35a provided on the upper side keeps holding the sheet paper P with the lower end surface of the machine frame 29.

As described above, when the user sits on the toilet seat body 5 to rotate the cam member 42 through the actuating lever 43 by a certain angle, the sheet paper P in the paper delivery path 32 is centered around the perforations 61. As one pinching point is pinched by the paper pinching member 35a and the machine frame 29, and the other pinching point is pinched by the paper pinching member 35 provided on the slide member 17 and the projection 36a of the swing plate 36 (two-point pinching). ), And
With the movement of the slide member 17, the sandwiched portion between the paper sandwiching member 35 and the protrusion 36a is strongly pulled toward the paper delivery port 46 side. At this time, the swing plate 36
Since the projection 36a comes into contact with the paper holding member 35 and rotates by the movement of the slide member 17 to strongly press the paper holding member 35, the sheet paper P can be pulled strongly without slipping. As a result, a large tension is applied to the sheet paper P between the paper sandwiching members 35, 35a, and the sandwiching members 35, 35a.
The perforations 61 existing therebetween are torn and forcibly broken by the application of the tension, and the sheet paper P is cut.

After cutting the sheet paper P, as shown in FIG.
The sheet paper P is a swing plate 36 and a paper holding member.
Since it is sandwiched between 35 and 35, the user can
Even if the body is moved a little above, it will not be displaced. After this, the user punches out the sheet paper P with the tongue piece 62.
Is hung down in the Western style toilet 3 leaving a part of the sheet paper P as shown in FIG. The punching tongue 62 may be made to hang down in the toilet bowl 3 when the sheet paper P is delivered onto the toilet seat body 5.

When the user finishes the work and leaves the toilet seat body 5, the toilet seat body 5 is regulated by the urging force of the shock absorbers 14 and 14 provided in the lifting guide boxes 12 and 12, as shown in FIG. It is pushed up until it comes into contact with the plate 15 and returns the toilet seat body 5 to its original position as shown by the solid line in FIG. On this occasion,
In the shock absorbers 14 and 14, when the load applied to the toilet seat body 5 is released, the pistons 14b and 14b move upward in the cylinder 14a against the resistance force of the silicone oil 14h by the biasing force of the compression springs 14g and 14g. Upon the upward movement of the pistons 14b, 14b, the second circulation holes 14f, 14f are closed by the check valves 14e, 14e, so that the silicone oil 14h can flow only through the small-diameter first circulation hole 14d. Therefore, the upward movement speed of the pistons 14b, 14b is
It will be much slower than when descending. That is, the toilet seat body 5 returns to its original position by moving up more slowly than during the lowering operation.

As the toilet seat body 5 returns to its original position, the pivotal fulcrum of the actuating lever 43 on the side of the pivot shafts 6 and 6a also rises, and the shaft rod 41 attached to the other end of the actuating lever 43 is rotated clockwise to move the cam member 6 from the position shown in FIG. 6, that is, the position where the slide member 17 is slid to hold the sheet paper P fed out on the toilet seat body 5 before the sheet paper P shown in FIG. 4 is held. The sheet paper P is unpinched by returning to the state (home position). When the sheet paper P is unpinched, that is, when the user stands up from the toilet seat body 5, the load on the toilet seat body 5 is released, but the shock absorbers 14, 1
Since the toilet seat body 5 starts to rise gently due to the action of 4, the sheet paper P is pinched between the paper pinching members 35, 35a and the lower end surface of the machine frame 29 and the swing plate 36, and is immediately pinched. Since it is not released, the sheet paper P does not cling to the user when the user leaves the toilet seat body 5. Then, when the toilet seat body 5 starts to move upward, the engagement roller 39 of the slide member 17 moves from the second cam groove e of the cam member 42 to the first cam groove d side and is engaged, The slide member 17 is retracted by the spring 34, the pushing up of the storage frame 33 is released, and the paper holding members 35 and 35a are retracted from the paper delivery path 32 into the installation space a of the inclined ceiling wall 17a. Make sure that there is no hindrance to the feeding of the sheet paper P. Further, since the swing plate 36 also releases the contact with the paper holding member 35 by the retraction of the slide member 17, it is rotated to the original position side by the force of the spring member 37, and is brought into contact with the restricting portion 38 of the machine frame 29. Hold and feed paper 32
Is opened so as not to prevent the sheet paper P from passing through.

Since the sheet paper P fed onto the toilet seat main body 5 is released from the toilet seat main body 5 by the user, the sheet paper P is released from the toilet seat main body 5. Therefore, when flush water is poured into the Western-style toilet 3 in this state, The punching tongue piece 62 is dragged into the toilet bowl 3 by the water force of the washing water, and the sheet paper P on the toilet seat body 5 is automatically pulled into the toilet bowl 3 and discharged together with the dirty water.

When the next user needs the sheet paper P again, the same operation as described above may be performed.

Also, if the paper feeding switch 52 is accidentally turned on while seated, the electric motor is operated while the seating detection means 53 detects seating.
Since the program is set in the memory 56 so that the drive command is not sent to the 20, the accident that the next sheet of paper P is unintentionally taken out while seated and causes a paper jam in the paper sending path 32 can be avoided. can do.

Further, at the time of feeding the sheet paper P, a portion of the installation space a of the inclined ceiling wall 17a where the upper surface paper holding members 35, 35a do not exist is closed by the paper guide plate 44, and the lower surface of the suspension support frame 29 is closed. Since the paper jam prevention plate 45 is attached except the portion through which the protrusion 36a of the swing plate 36 can pass, the sheet paper P fed to the paper delivery path 32 is provided.
Can be smoothly guided by the paper guide plate 44 and the paper jam prevention plate 45, and can be fed out without causing paper jam.

In addition, during feeding of the sheet paper P, the paper feeding path
In the present embodiment, when a paper jam occurs in 32, the time required for feeding out the sheet paper P is set by the timer 57. Therefore, even if this set time elapses, the paper position detection sensor 51 detects the sheet paper P. If the through hole 50 is not detected, it is determined that there is a paper jam or there is no paper, and the paper trouble lamp 64 shown in FIG. 1 lights up to notify the user that a paper jam has occurred. Has been done.

[Effect of device]

As described above, the present invention, when seated on the toilet seat body,
Even if a large impact force is applied to the pivotal support portion of the toilet seat body by buffering the descending movement of the toilet seat body to the pivotal support portion, this can be reliably received and damage to the pivotal support portion can be prevented. it can.

The cushioning device causes the lowering operation of the toilet seat body to be performed relatively quickly, and conversely, when the toilet seat body is moved up, the speed thereof is delayed so that the user can hold the sheet paper for a long time after the user leaves the toilet seat body. Therefore, it is possible to eliminate the drawback that the sheet paper is caught around the user's body when the user leaves the toilet seat body.
