Description

[Detailed Description of the Invention] [Industrial field of application] The present invention automatically supplies sheet paper that can be flushed and discarded to the toilet seat and automatically lays it so that the Western-style toilet can be used hygienically. The present invention relates to a device for preventing erroneous operation of a toilet seat.

[Conventional technology]

In recent years, many Western style toilets have come to be used in hotels, restaurants, homes and the like. Since this western style toilet is used by sitting on a toilet seat that is mounted upright on the toilet, it is desirable that the toilet seat is always hygienic. For this reason, the cloth cover is attached to the toilet seat, which is apt to become unsanitary due to splashes of sewage and the like in ordinary households, to prevent the toilet seat from becoming unsanitary. Rather than maintaining good hygiene, it is often used to prevent people from feeling cold when sitting on the toilet seat. However, attaching the cloth cover to the toilet seat makes it easy to overlook the fact that dirty water has adhered to the toilet seat, which may rather promote unsanitary conditions. On the other hand, western style toilets installed in public places such as hotels, restaurants and public transportations used by unspecified large numbers of people usually do not use the toilet seat cover. Therefore, regardless of whether or not a cover is provided on the toilet seat, there is no difference in that splashes of sewage adhere to the toilet seat, and the use of such a Western-style toilet by a large number of unspecified people is a major public health problem. There is a problem, and nowadays, there is an increasing social demand for hygienic use of Western-style toilets installed in public places from the viewpoint of public health.

For this reason, recently, for example, as shown in Japanese Utility Model Laid-Open No. 60-155399, when using a Western-style toilet bowl, a large-sized sheet paper that covers the toilet seat is electrically driven by a feeding roller. A so-called automatic sheet-paper feed toilet seat has been developed in which the sheet paper is automatically laid on the toilet seat by feeding it onto the toilet seat for a predetermined length and then cutting it with a cutter. Further, the user can sit on the toilet seat through the sheet paper, which is very hygienic.

[Problems to be solved by the device]

However, in the seat paper supply toilet seat, when sitting on the toilet seat, the Western-style toilet bowl can be used hygienically due to the presence of the seat paper, while when the seat paper is not needed, if the operation switch is operated by mistake, The paper may be fed automatically. In consideration of the fact that this type of toilet seat is used by men and women of all ages, or by an unspecified number of people, when the sheet paper is not needed, for example, when the boy is taking a dip, the toilet seat should be erected to stand up. In some cases, or when the user sits on the toilet seat via the sheet paper, it is at least necessary to prevent the sheet paper from being drawn out even if the operation switch is operated. When the sheet paper is fed out in these cases, the sheet paper may be soiled, a paper jam phenomenon may occur, and the sheet paper may not be smoothly delivered thereafter, or the sheet paper may be soiled or unnecessary. There are various problems such as the waste of the sheet paper due to the feeding out of such sheet paper, and there has been an urgent need to solve these problems when the automatic sheet-paper feed toilet seat spreads.

[Means for Solving the Problems]

In view of the above problems, the present invention allows a hinge shaft to be freely rotated through a hinge piece at the rear of a toilet seat in an end box extending toward the front side of the toilet seat at both ends of a box in which a functional portion is housed and arranged. Attached to the hinge shaft protruding into the end box, for operating a stop switch for lowering the energizing circuit of the electric motor for feeding the sheet paper when the seat is seated on the seat and when the seat is raised. It is an object of the present invention to provide an erroneous operation preventing device for a sheet-paper automatic feed toilet seat, in which a driving body and an operating rod are attached so as to be interlocked with the hinge shaft, and the sheet-paper is prevented from being fed out when it is not needed.

[Action]

The present invention moves the driver up and down by moving up and down the hinge shaft attached to the hinge piece that pivotally supports the toilet seat, and turns on and off the stop switch that opens and closes the energizing circuit of the sheet paper feeding and breaking motor. The feature is that the operation is performed.

As shown in FIG. 15, the electric motors 15 and 21 are connected in series to a power source, and the operation of the electric motors 15 and 21 is sequence controlled by the controller S.

Next, the operation will be described.

First, the case where the toilet seat 2 is erected for men's small use will be explained. In response to the erection of the toilet seat 2, the hinge shaft 4a is also changed from the state shown in FIGS. 4 and 5 to the state shown in FIGS. 8 and 9. To rotate about 90 °. When the hinge shaft 4a rotates, the operation rod 36, which is urged by the compression spring 35a so that its upper end contacts the flat surface of the cam projection 31, is a cam that cooperates with the rotation of the hinge shaft 4a. It is pushed by the boundary edge between the flat surface and the arcuate surface of the protrusion 31 and gradually resists the force of the compression spring 35a to move the ninth edge.
As shown in the figure, it descends into the fitting hole 37. Then, when the toilet seat 2 reaches the upright state, the operation piece 39, which is projected from the upper end of the operation rod 36 and keeps pressing the push button i of the stop switch 41, descends as shown in FIG. The stop switch 431 is cut off. When the stop switch 41 is cut off, the energizing circuits of the electric motors 15 and 21 are opened as shown in FIG. 15, so that even if the paper feeding switch P is operated, the feeding device 5 is not driven at all. , The delivery port of the box 6
Since the sheet paper 9 is never fed out from 14,
It is possible to reliably prevent an erroneous operation in which the sheet paper 9 is fed out when the toilet seat 2 is erected.

Next, a case where the user sits down on the toilet seat 2 to make an extra effort, the toilet seat 2 in the upright state is tilted down on the toilet bowl 1 and the sheet paper 9 is fed onto the toilet seat 2. In this case, the user is not seated on the toilet seat 2.

First, when the toilet seat 2 in the upright state is laid down so that it can be seated on the toilet 1, the hinge shaft 4a responds to it and rotates about 90 ° counterclockwise from the state shown in FIGS. 8 and 9. To do. Due to the rotation of the hinge shaft 4a, the operating rod 36 pushed by the boundary edge between the flat surface and the arcuate surface of the cam projection 31 is the hinge shaft when the toilet seat 2 is upright.
Due to the rotation of 4a, the flat surface of the cam projection 31 becomes
As shown in the figure, when it is rotated to a position corresponding to the upper end of the operating rod 36, it is pushed up by the biasing force of the compression spring 35a to the original position shown in FIG. The push button i of the stop switch 41 is pushed by the piece 39 to turn on the stop switch 41. When the stop switch 41 is turned on, the energizing circuits of the electric motors 15 and 21 are closed as shown in FIG. This is an example in which the toilet seat 2 in the upright state is laid down on the toilet bowl 12, but if the toilet seat 2 is in the laid down state from the beginning, the stop switch 41 operates as shown in FIG.
Has already been pressed by the operating piece 39 of the operating rod 36 and is in the closed state, so that the energizing circuits of the electric motors 15 and 21 are closed. In this state, turn on the power switch 27 and turn on the power lamp.
Check that 28 is lit. After that, the paper feeding switch P is turned on to start the electric motor 21, and the movable plate 17 shown by a two-dot chain line in FIG. 11 is shown by a solid line in FIG.
Rotate to a position parallel to the paper feed path 18
Is once stopped by a command from the control device S. Subsequently, the electric motor 15 is activated by a command from the control device S. As a result, the sheet paper 9 nipped by the feeding roller 13 and the pressing roller 16 is gradually rewound from the rolled state and fed onto the toilet seat 2 via the movable plate 17 → the feeding port 14. Then, when the sheet paper 9 is fed out on the toilet seat 2 for a certain length, the through hole 26 provided in the sheet paper 9 is detected by the sensor 25, and the electric motor 15 is stopped by a command from the control device S. Therefore, the sheet paper 9 is fed out on the toilet seat 2 in a fixed amount, and the perforations 29 are set between the breaking projection 12 and the feeding roller 13. Thereafter, the electric motor 21 is activated by a command from the control device S, the cam member 20 is rotated clockwise in FIG. 11, and the movable plate 17 interlocked with this is moved counterclockwise via the driven roller 19, That is, the rotary plate 11 is rotated. By the rotation of the movable plate 17, a part of the sheet paper 9 in the paper delivery path 18 is lifted to the side of the rotation plate 11 and is sandwiched between the movable plate 17 and the cushioning materials b and g of the rotation plate 11. It After that, the cam member 20 continues to rotate to rotate the movable plate 17 toward the rotating plate 11, and the rotating plate 11 is rotated clockwise about the pivot axis a. As a result, the sheet paper 9 is applied with a large tension between the movable plate 17 and the feeding roller 13 and, at the same time, is strongly pressed partially by the breaking projection 12. Therefore, in conjunction with the fact that the sheet paper 9 is subjected to a large tension, the perforations 29 near the breaking projection 12 cannot withstand the pressing force of the breaking projection 12 and are torn sequentially from that portion, as shown in FIG. As described above, one sheet of paper 9 can be smoothly broken. After the sheet paper 9 is ruptured, the motor is driven by a command from the control device S.
21 is temporarily stopped, and the sheet paper 9 is held between the movable and rotating plates 17 and 11. In this state, the user sits on the toilet seat 2 via the sheet paper 9 to perform additional work such as wearing.

As described above, when the user sits on the toilet seat 2, the rear part of the toilet seat 2 is shown in FIG. 10 along the longitudinal insertion holes 44 provided in the end boxes 6a, 6b via the hinge shafts 4, 4a. X descends in the direction of the arrow. As the hinge shafts 4 and 4a descend, one of the hinge shafts 4a
The drive body 33, the cam projection 31, and the operation rod 36 that are in contact with the push button i are inserted into the fitting holder 34 and the fitting hole 37 against the compression springs 35 and 35a. As a result, the push button i is released, and the closed state of the stop switch 41 is released. As shown in FIG. 15, the energizing circuits E of the electric motors 15 and 21 are released.
As a result of being opened, even if the user accidentally presses the paper feeding switch P when the user is sitting on the toilet seat 2, the electric motor
Since the sheets 15 and 21 are not activated, it is possible to prevent the sheet paper 9 from being unintentionally taken out or the state in which the sheet of paper 9 is pinched by the movable and rotating plates being cancelled.

When the user leaves the toilet seat 2 after finishing work, the hinge shaft 4a of the toilet seat 2 is driven by the biasing force of the compression springs 35, 35a.
3. Since it is lifted to the original position shown in FIG. 4 via the operating rod 36, the stop switch 41 is reclosed by the operating piece 39 of the operating rod 36 to reclose the energizing circuits of the electric motors 15 and 21. Therefore, the electric motor 21 for driving the cam member 20 starts to be activated by a command from the control device S, and the movable member 17 is closed by the cam member 20 as shown by a chain double-dashed line in FIG. The sheet paper 9 is unpinched while being returned to the original position side so as to be. When the sheet paper 9 is released, the punching piece 9a is washed by the water force of the washing water for washing the inside of the toilet 1.
Is dragged into the toilet 1 and discharged together with the dirty water.

Incidentally, when the next user sits on the toilet seat 2 to perform extra work, the sheet paper 9 can be delivered onto the toilet seat 2 by operating the paper delivery switch P, as described above.

[Effect of device]

Since the present invention is configured as described above, it has the following effects.

In the present invention, when it is not necessary to pay out the sheet paper on the toilet seat, that is, when the toilet seat is raised or seated on the toilet seat, the toilet seat can be slidable and vertically movable on the toilet bowl. An operating rod provided so as to be interlocked with the hinge shaft descends on one of a pair of pivotally supported hinge shafts, and a stop switch arranged in the vicinity of the hinge shaft is cut off, thereby feeding and breaking the sheet paper. Since the erroneous operation prevention device configured to open the energization circuit of each electric motor for use is provided, the seat generated by erroneously operating the paper feeding switch when the toilet seat is standing and seated on the toilet seat. It is possible to reliably solve the problem that the paper is fed out. As a result, it is possible to reliably prevent a paper jam caused by careless feeding of the sheet paper due to an erroneous operation of the sheet paper automatic feed toilet seat, and unnecessary feeding.

Further, the erroneous operation preventing device is configured such that hinge shafts provided at both ends of a back portion of a toilet seat are rotatably attached to an end box protruding on both sides of a box body having a functional section housed therein. In the end box, the hinge shaft protruding to the end is provided with an operation rod for operating a stop switch that moves downward when seated on the toilet seat or when the toilet seat is erected and opens the energizing circuit of the electric motor for feeding the sheet paper. Since the erroneous operation preventing device is mounted so as to be movable in cooperation with the hinge shaft, the erroneous operation preventing device can be installed in the end box that rotatably supports the hinge shaft without increasing the mounting space of the toilet seat itself. By effectively utilizing the protruding end of the narrow hinge shaft that protrudes, the structure is simplified with a small number of parts, and with the simplification of the structure, it is economical and good without hindering the sliding operation of the toilet seat.
