DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a toilet seat with a seat cover in which, when a Western toilet is used, the upper surface of the toilet seat is automatically covered with sheet paper so that the Western toilet can be used in a sanitary manner.

[Prior art]

In recent years, with the westernization of life, many Western style toilets have been used in restaurants, hotels, general households, and the like. However, when using a Western style toilet, the ass is placed directly on the toilet, that is, because the skin directly touches the toilet seat, there is a certain feeling of strangeness in Japanese with good cleanliness. For this reason,
For example, in ordinary households, the above problem is solved by covering a toilet seat with a cloth or knitted yarn cover. However, in a toilet used by an unspecified number of people, such as hotels, restaurants, trains, and passenger planes, even if the cover is put on, unlike a general home, it is a strong resistance to touch a toilet seat used by strangers without knowing it. There is. For this reason,
In hotels and the like that are used by many people, there are many cases where the user uses toilet paper on the toilet seat for convenience, but this is very troublesome for the user, and today the toilet seat is always used. The desire for hygienic use, covered with fresh covers and the like, is increasing day by day.

[Problems to be solved by the invention]

For this reason, for example, as shown in Japanese Patent Application Laid-Open No. 60-225529, before using the Western style toilet, before sitting on the toilet seat, it is large enough to cover the toilet seat, and in the center part An elliptical punching part having a size corresponding to the toilet seat opening part is provided with its part connected to the outer edge, and the water-soluble sheet-like toilet seat cover is taken out one by one from the storage box and put on the toilet seat. Accordingly, a toilet seat with a seat cover that can use a Western-style toilet in a sanitary manner has been proposed.
When using the sheet-shaped cover, the cover is placed on the toilet seat, and the seat is seated. Subsequently, the connection of the punched portion is disconnected, only the punched portion is dropped into the toilet, a part of which is submerged, and added. Thereafter, the toilet seat cover is dragged into the toilet bowl by the outflow of the washing water, and is discharged out of the toilet bowl together with defecation. As described above, when using a Western-style toilet, it is very sanitary if toilet paper or a dedicated toilet seat cover is placed on the toilet seat and seated. However, as described above, when the toilet seat is used in a clean state, it is very troublesome to lay a toilet paper or a sheet-shaped toilet seat cover on the toilet seat each time to perform the addition. That is, in the case of toilet paper, it is very narrow, and even when placed on the toilet seat successfully,
If you move your body in the middle of sitting, the paper itself moves with it, and part of the buttocks may directly touch the toilet seat. In this case, since an appropriate amount of toilet paper was added again, it was not hygienic.
When a sheet-shaped toilet seat cover is used, it is a large sheet of about 40 to 50 cm because of the upper surface of the toilet seat, and
The paper is a soft thin leaf that can be washed and discarded like toilet paper. Therefore, the stiffness is very weak, and such a large thin paper can be removed from the storage box as needed.
It is difficult to take out one sheet at a time, especially since the punched part corresponding to the center part of the toilet seat cover is provided, it is easy to break from the punched part toward the outer edge of the toilet seat cover when pulling it out of the storage box, making it unusable Often.
In addition, it is very difficult to use and uneconomical, for example, a plurality of sheets may be simultaneously pulled out. In addition, the toilet seat cover consisting of a large sheet cover was folded one by one like a tissue paper and stored in the storage box, but it was a large thin sheet of paper, and the center part of the toilet seat cover was easy to hang down in the toilet bowl. It is practically difficult to fold the sheet-shaped toilet seat cover provided with the hollow part, and it is also difficult to mechanize it.In the end, since it will be folded by skilled hands, productivity is very poor and cost is high. There were disadvantages.

[Means to solve the problem]

The present invention has been made in view of the above-mentioned problems, and a sheet-shaped toilet seat cover that covers the upper surface of a toilet seat is reliably drawn out one by one onto the toilet seat by electric operation without being manually pulled out, and the toilet seat is covered. It is intended to provide a toilet seat with a seat cover, which can be used while sitting on the toilet seat with added hygiene when used.

[Operation]

The drive shaft 31 is rotated via the worm wheel 35, and the drive disk 32 eccentrically attached to the tip of the drive shaft 31 is rotated rightward in the cam hole 21 shown in FIG. As a result, the cutting cutter 18 moves upward by the cam action of the driving disk 32. At this time, the pressing plate 15, which is cooperatively connected to the cutting cutter 18 via the engaging pieces 17, 17, also moves upward by the force of the compression spring 23, and the upper end thereof receives the pressure as shown in FIG. Body 25 mating groove 26
And the sheet paper 40 positioned on the side of the paper outlet 42 slightly passing through the perforation 40b is sandwiched between the pressure receiving body 25 and the entire width thereof. On the other hand, the part of the sheet paper 40 that continues from the perforation 40b to the inside of the delivery path 41 is
As shown in FIG. 7, the entire width of the sheet paper 40 is sandwiched between the sheet feeding roller 7 and the pressing roller 10 in the same manner as in the case of the pressing plate 15. That is, the role of the paper feed roller 7 and the pressing roller 10 in the present invention is to feed the sheet paper 40 in a fixed amount and to hold the sheet paper 40 at a constant interval by the pressing plate 15. In this way, the sheet paper 40 is
With both ends in the middle and holding the drive disc 32
Is rotated, and this time, only the cutting cutter 18 is moved upward against the force of the compression spring 23, and its blade portion is pressed by the pressure receiving member shown in FIGS.
25 is inserted into the slot 27. As a result, the sheet paper 40 sandwiched between the pressing plate 15 and the paper feed roller 7 becomes the eighth paper.
As shown in the figure, while the tension is released by the cutting cutter 18 entering the slot 27, the tension is finally released as the cutter 18 further moves deeper into the slot 27, that is, the perforations 40b are broken. Thus, the cutting of the sheet paper 40 is completed.
When the cutting of the sheet paper 40 is completed, the driving disk 32 further rotates to the right, lowers the cutter 18 from the inside of the slot 27, and then the pressing plate 15 moves down together with the cutter 18,
Returning to the original position as shown in FIG. 5, the operation of the electric motor 33 is stopped at this time by a command from the control device. As described above, when the cutting of one sheet of paper 40 covering the toilet seat 3 is completed, the sheet paper 40 covering the toilet seat 3 is automatically placed on the toilet seat 3 as shown in FIG. Can be laid. After this, the user can use sheet paper 40
The toilet seat 3 is seated from above, the connecting portion (not shown) in front of the punching portion 40a is broken, and the punching portion 40a is inserted into the toilet 1 through the central opening 3a of the toilet seat 3 as shown in FIG. Hang it down. In this state, the replenishment is performed, and when the washing water is flown when the addition is completed, the punched portion 40a of the sheet paper 40 is pulled together with the washing water to a deep portion in the toilet bowl 1, whereby the sheet laid on the toilet seat 3 The entire paper 40 and the toilet 1 are pulled and discharged together with the defecation. When using sheet paper without perforations, a cutter having a knife-shaped or saw-toothed cutter may be used. When the perforations 40b of the sheet paper 40 are to be broken, the sheet feeding roller 7 is rotated in the opposite direction to the time when the sheet paper 40 is sent out, instead of the cutting cutter.
The 40 perforations 40b may be broken. Further, when the sheet paper 40 is sent out or the driving unit 30 is operated, the cooling fan 47 is rotated by the electric motor 6.33 to cool the electric motor 6.33, and this cool air passes from the air hole 46 to the lower side of the outlet passage 41, and Since the sheet paper 40 is discharged to the delivery path 41, the sheet paper 40 can be delivered in a state of being slightly lifted in the delivery path 41 by using cold air at the time of delivery, and the sheet paper 40 may cause paper jam. And can be sent out smoothly.

【The invention's effect】

As described above, in the present invention, when feeding a sheet of paper wound in a roll, the paper is sandwiched and sent out by a feed roller and a press roller provided in a straight shape, and when the sheet is cut, Since it is configured to be cut (breaked) by the cutting cutter while being pressed by the pair of rollers and the pressing plate, there is an advantage that the feeding and cutting structure of the sheet paper can be simplified. Also, the sheet paper can be automatically fed onto the toilet seat by operating the switch,
The user does not need to lay sheet paper on the toilet seat as in the related art, and can sanitarily use the Western-style toilet installed at a place used by an unspecified number of people.
