[Prior art]

Thorough maintenance of sewers in recent years has promoted the popularization of flush toilets that purify toilet excrement in septic tanks and flush it into the sewers. Using, the old dirty image is renewed, and it has a feeling of cleanliness. On the other hand, based on the rapid economic growth, the restaurant industry such as restaurants and restaurants, the service industry in which an unspecified number of people enter and leave, such as hotels and wedding halls, have been disrupted. Is increasing with the improvement of. Such an unspecified number of people enter and leave the service industry, and the use of these restaurants and hotels is increasing with the improvement of living standards. The restrooms of restaurants, hotels, etc. where an unspecified number of people come and go have changed from conventional batch type flush toilets to flush flush toilets in terms of hygiene and cleanliness. As for these flush toilets, the western style in which a toilet seat that can withstand continuous use over a long period of time is overwhelmingly common. An unspecified number of people who use the toilet seat of a Western-style toilet in such restaurants and hotels will also use it. This type of Western-style toilet seat that sits on the toilet seat is used by placing the buttocks on the toilet seat, and because it is used by an unspecified person, it is unknown what kind of person used it. In some cases, it may be unclean, and in particular, illness may be transmitted. Therefore, recently, in order to sterilize and disinfect the top of the toilet seat, a toilet seat disinfecting cleaner in which a chemical solution is soaked in a paper that wipes the top of the toilet seat cleanly has been developed and is generally commercially available. However, this toilet seat disinfecting cleaner uses sturdy paper because it cleans the top of the toilet seat cleanly, and if it is thrown into the toilet after use, it may clog the toilet, etc., so it must be disposed of separately. It takes time and effort. The toilet seat of this Western-style toilet is usually made of hard plastic. Therefore, sitting directly on this hard plastic toilet seat is cold and difficult to use in the winter. In particular, after the toilet seat disinfectant cleaner is wiped clean, the chemical solution contained in the toilet seat disinfectant cleaner adheres to the surface of the toilet seat, making it extra cold and difficult to use. Therefore, in order to prevent unsanitary conditions caused by direct skin contact with the toilet seat and to soften the coldness even when sitting on the toilet seat in winter, recently a toilet seat paper is laid on this toilet seat. The method of using it has come to be considered. This sheet for toilet seat is stacked one by one in the vicinity of the toilet seat and stored in a storage body such as a bag, and either one sheet is taken out from the storage body as needed and used. A special toilet seat is used, which is remodeled so that the roll can be stored by winding the paper around the roll so that it can be supplied continuously.

[Problems to be solved by the device]

However, in the supply of such a toilet seat cover sheet for a conventional toilet bowl, the sheets are stacked one by one and stored in a container such as a bag, and the sheets are taken out from the container one by one as needed. If it is used, there is a problem that a space for accommodating the toilet seat sheet is taken in a small toilet space and a large amount of sheet cannot be set at one time. Also, in the case of a toilet bowl that is configured so that it can be continuously wound by winding the toilet seat cover on a roll, the toilet seat cover is set when a new toilet is built or when the toilet is rebuilt. It can be used by adopting a special toilet bowl that can be used, but it has a problem that it cannot be used at all in the existing toilet bowl. Furthermore, in the case of a conventional toilet bowl that is configured to be wound around a roll so that it can be continuously supplied, it is necessary to remove the existing toilet bowl and replace it with a modified toilet bowl. Have The present invention has been made in view of the above problems of the conventional technology, and its purpose is to be easily attached to an existing toilet bowl by opening and closing the lid portion of the toilet bowl. An object of the present invention is to provide an automatic toilet seat cover sheet feeder that can automatically and automatically unwind a sheet of paper that has been wound around a toilet sheet onto a toilet seat without touching it.

[Means for Solving the Problems]

In order to achieve the above object, the toilet seat automatic sheet feeder according to the present invention is rotated by opening a pawl attached to a lid of a toilet bowl and a pawl rotatably attached to the toilet bowl by engaging the pawl with the lid. A ratchet and a drive gear that rotates by receiving the rotation of the ratchet, and presses the ratchet against each other to rotate and sandwich the sheet for toilet seat and send it out onto the toilet seat 1
It is composed of a pair of rollers and a gear that is attached to one of the pair of rollers and meshes with the drive gear. A braking member is provided on one of the pair of rollers. In addition, the lid portion of the toilet bowl is provided with a paper feed release lever that releases the engagement between the pawl and the ratchet. Then, the paper feed release lever opens and closes the lid portion and opens and closes the toilet seat to press the pawl to release the engagement with the ratchet.

[Action]

One end of the toilet seat paper wrapped around the roll is inserted between the pair of rollers that are in pressure contact with each other, and the toilet seat paper is slightly pulled out from between the pair of rollers to close the toilet lid. When the lid of the toilet bowl is opened, the ratchet with which the claws attached to the lid portion of the toilet are engaged pushes and rotates the ratchet. Then, the drive gear is rotated by the rotation of the ratchet, and the gear is rotated by the rotation of the drive gear. The rotation of this gear causes one of the pair of rollers to rotate, and the toilet seat sheet sandwiched between the two rollers is sent out onto the toilet seat. By appropriately adjusting the number of gears of the drive gear and the number of gears of the drive gear, the toilet seat cover can be placed on the toilet seat by one opening movement of the lid portion of the toilet bowl. When the lid of the toilet bowl is closed, there is no engagement between the claw and the ratchet, and it runs idle. For this reason, the ratchet does not rotate and is not fed in the retracted direction, which is the reverse of the delivery of the toilet seat paper sandwiched between the two rollers. Rotation of the ratchet due to the movement of the pawl when the lid of the toilet is closed is prevented by a braking member provided on one of the pair of rollers. Further, when it is inconvenient that the toilet seat cover sheet is delivered onto the toilet seat by one opening operation of the lid portion of the toilet bowl, it is possible to release the engagement between the pawl and the ratchet by pressing the paper feed release lever. Even if the lid of the toilet bowl is opened and closed, it is possible to stop sending the toilet seat cover onto the toilet seat. Since this paper feed release lever is configured to operate by opening and closing the lid and opening and closing the toilet seat, when the toilet seat is opened and closed when the lid is opened and closed, the toilet seat presses the paper feed release lever, The release lever pushes the pawl to release the engagement between the pawl and the ratchet.

【Example】

Embodiments of the present invention will be described below. FIG. 1 shows an embodiment of the automatic toilet seat backing sheet feeder according to the present invention. In the figure, reference numeral 1 is an automatic toilet seat cover sheet feeding device attached to the rear portion of the toilet bowl 100. The toilet bowl 100 is a well-known western-style toilet, and includes a main body 110, an openable / closable toilet seat 120, and an openable / closable lid 130 that covers the toilet seat 120 from above. The toilet seat automatic paper feeder 1 is housed in a housing 2 and has a structure as shown in FIG. The lid 130 is rotatably attached to the shaft 3 fixed to the housing 2 of the toilet seat automatic spreader 1 by two legs 131 and 132. Reference numeral 4 is a claw, and 5 is a ratchet that meshes with the claw 4.
The ratchet 5 is provided inside the leg 131 of the lid 130, and is rotatably attached to the shaft 3. Also, nail 4
Is rotatably attached to the lid 130, and is always
It is biased in the direction shown by the arrow A in FIG. 3 by a biasing means (not shown). That is, the claw 4 is normally in a state of meshing with the ratchet 5. Therefore, when the lid 130 is opened as shown by the arrow A in FIG. 1, the pawl 4 attached to the lid 130 causes the ratchet 5 to rotate in the direction shown by the arrow A in FIG. A drive gear 6 is connected to the inside of the ratchet 5, and the drive gear 6 receives the rotation of the ratchet 5 and rotates in synchronization with the rotation of the ratchet 5. A roller 7 is rotatably attached to the shaft 3,
It is formed of an elastic material such as rubber or synthetic resin. A roller 8 is pressed against the roller 7. A gear 9 is attached to one end of the roller 8, and the roller 8 rotates together with the gear 9 as the gear 9 rotates. Therefore, the roller 7 is rotated by the rotation of the roller 8. The pair of rollers, roller 7 and roller 8, has a function of sandwiching the toilet seat cover sheet 13 wound around the cover sheet roll 12 and feeding the fixed amount together with the roller 7 as the roller 8 rotates. ing. The drive gear 6 is meshed with the gear 9. The number of teeth of the gear 9 and the number of teeth of the drive gear 6 are configured with a specific ratio. The number of teeth of the gear 9 and the number of teeth of the drive gear 6 are configured, for example, in a ratio of the number of gear teeth: the number of drive gear teeth ≈1: 6. 10 is a braking member pressed against the end of the roll 8,
The roll 8 is braked so that the roll 8 does not easily rotate. That is, when the lid member 130 is closed and opened from the position shown in FIG. 3 as shown by an arrow B in FIG. 3, the pawl 4 attached to the lid member 130 slides on the ratchet 5 when the lid member 130 is closed and opened. This is for preventing the ratchet 5 from rotating in the direction shown by the arrow C in FIG. Reference numeral 11 denotes a paper feed release lever, which pushes the pawl 4 at its tip by pressing in the direction shown by the arrow D in FIG. 3 to release the meshing between the pawl 4 and the ratchet 5. The paper feed release lever 11 is attached to the outside of the leg 131 of the lid 130, and is normally urged in the direction shown by the arrow E in FIG. Has become. Further, the paper feed release lever 11 is provided with a lid 13
0 is closed as shown in FIG. 1, toilet seat 1
The upper surface of 20 is pressed and moved. Therefore, when the lid portion 130 is closed as shown in FIG.
Is pushed up, and the engagement between the claw 4 and the ratchet 5 is released. Therefore, when the toilet seat 120 is opened together with the lid 130 when the lid 130 is opened, the engagement between the pawl 4 and the ratchet 5 is released even when the lid 130 is opened, and thus the pawl 4 is released.
Therefore, the toilet seat backing sheet 13 wound around the backing sheet roll 12 is not sent out without rotating the ratchet 5. Since it is configured as described above, first, one end of the toilet seat cover sheet 13 wound around the cover sheet roll 12 is inserted between the pair of rollers 7 and 8 which are in pressure contact with each other.
The toilet seat paper 13 is slightly pulled out from between the pair of rollers 7 and 8 to close the lid 130 of the toilet 100. After that, toilet bowl 1
4 is opened as shown by an arrow A in FIG. 4, the claws 4 attached to the lid 130 of the toilet bowl 100
The ratchet 5 engaged with is pressed and rotated as indicated by an arrow B in FIG. Then, the drive gear 6 is rotated by the rotation of the ratchet 5, and the gear 9 is rotated by the rotation of the drive gear 6. 1 by the rotation of this gear 9
One of the pair of rollers 7 and 8 rotates, and the toilet seat cover sheet 13 sandwiched between the two rollers 7 and 8 is delivered onto the toilet seat 120 as shown by an arrow C in FIG. The ratio between the number of gears of the drive gear 6 and the number of gears of the gear 9 is such that the drive gear 6 rotated by one rotation of the ratchet 5 causes the two rollers 7 and 8 to rotate so that the toilet seat cover sheet 13 is placed on the toilet seat 12.
The ratio is such that the roller 8 can be rotated enough to be sent to a fixed position above zero. Therefore, the toilet seat cover sheet 13 can be placed at a fixed position on the toilet seat 120 by one opening movement of the lid 130 of the toilet bowl 100. When the lid 130 of the toilet bowl 100 is closed, the pawl 4 slips on the gear of the ratchet 5 and does not mesh with the gear of the ratchet 5, so that the pawl 4 idles. That is, the ratchet 5 does not rotate due to the action of the pawl 4.
Therefore, the toilet seat cover sheet 13 sandwiched between the two rollers 7 and 8 is not fed in the direction opposite to the direction in which the two rollers 7 and 8 are fed, that is, in the retracted direction. Further, the rotation of the ratchet 5 due to the movement of the claw 4 when the lid 130 of the toilet bowl 100 is closed is prevented by pressing the end portion of one of the pair of rollers 7, 8 to apply a brake. It is also done by 10. Also, for example, a toilet seat 12 such as a man standing for urine
Toilet 10 when you sit down on 0
When it is not necessary to send the toilet seat cover sheet 13 onto the toilet seat 120 by opening and closing the lid 130, the paper feed release lever 11 is pushed to release the engagement between the pawl 4 and the ratchet 5. When the engagement between the claw 4 and the ratchet 5 is released by the paper feed release lever 11, the toilet seat cover sheet 13 is not delivered onto the toilet seat 120 even if the lid portion 130 of the toilet bowl 100 is opened and closed. When the lid 130 of the toilet seat 100 is opened and closed together with the toilet seat 120, the toilet seat 120
The lid portion 130 is opened and closed while the paper feed release lever 11 is pressed on the upper surface of the sheet, so that the opening / closing of the lid portion 130 does not send the toilet seat cover sheet 13 onto the toilet seat 120. FIG. 5 shows another embodiment of the automatic toilet seat backing sheet feeder according to the present invention. In the figure, this embodiment differs from the embodiment shown in FIGS. 1 to 3 in that the roller 7 of the embodiment shown in FIG. 3 forms one roller and the roller 8 serves as a driving roller. In contrast to this, in the present embodiment, the width of each of the both ends of the shaft 3 fixed to the housing 2 of the toilet seat automatic spreader 1 in which the lid 130 is rotatably fitted is set. Thin rollers 20, 2
1, the roller 20 is a drive roller that rotates by receiving the rotation of the ratchet 5, and the drive gear 6 attached to the shaft 3 and the gear fixed to the roller 8 in the embodiment shown in FIG. 9 is removed. Therefore, the pair of rollers 20 and 21 is adapted to be rotated by the rotation of the ratchet 5 which is rotated by the pressing of the claw 4 and the rotation of the roller 20. Other than that, there is no difference from the embodiment shown in FIGS. Therefore, also in this embodiment, the same effect as that of the embodiment shown in FIGS. 1 to 3 can be obtained.
