Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a toilet seat equipped with a sheet paper supply device that automatically spreads sheet paper on the top surface of the toilet seat to enable sanitary use of the Western-style toilet bowl.

[Conventional technology]

In recent years, as lifestyles have become more Westernized, many Western-style toilet bowls have come into use in restaurants, hotels, general households, and the like. However, when using a Western-style toilet, one rests one's buttocks directly on the toilet seat, which means that one's skin comes into direct contact with the toilet seat, which is something that Japanese people, who tend to be very clean, find it strange. For this reason,
For example, in ordinary households, the above-mentioned problem is solved by covering the toilet seat with a cloth or woolen seat cover. However, in toilets used by an unspecified number of people, such as in hotels, restaurants, trains, and passenger planes, even if the cover is covered, unlike in ordinary homes, there is a strong sense of reluctance to touch a toilet seat that has been used by a stranger. There is. For this reason,
In the toilets of hotels and other facilities used by many people, users often place toilet paper on the toilet seat for hygiene reasons. However, this is extremely troublesome for users, and today, The desire for the toilet seat to always be covered with a fresh cover and to be used hygienically has increased by 8.

[Problems to be solved by the invention]

For this reason, for example, as shown in Japanese Unexamined Patent Publication No. 60-225529, before sitting on the toilet seat when using a Western-style toilet, it is necessary to use a toilet with a size that can sufficiently cover the top of the toilet seat and in the center. An oval punched part with a size corresponding to the opening of the toilet seat connects a part of the water-soluble paper sheet to the outer edge.The paper sheet is taken out one by one from the storage box and placed over the entire top surface of the toilet seat. Accordingly, a toilet seat equipped with sheet paper for sanitary use of a Western-style toilet has been proposed. When using the sheet-like paper, cover the toilet seat with the paper, sit down, then separate the connecting part of the punched part, let only the punched part hang down in the toilet bowl, and partially submerge it in water. After urinating, the sheet paper is dragged into the toilet bowl by the outflow of flushing water, and is carried out of the toilet bowl along with the defecation. In this way, when using a Western-style toilet, it is very hygienic to sit on the toilet seat with toilet paper or a special sheet paper that covers the toilet seat. but,
As mentioned above, in order to use the toilet seat in a clean state, it is very troublesome to use toilet paper or large sheet paper on the toilet seat each time to use the toilet seat. For example, toilet paper has a very narrow width, and even if you place it on the toilet seat, if you move your body when you sit down or while sitting, the paper itself will move all over the place. Part of your butt may come into direct contact with the toilet seat. In this case, the user had to refill the appropriate amount of toilet paper, which was very troublesome. In addition, when using a large sheet paper as a toilet seat cover, the paper must be about 40 to 50 cm large to cover the top of the toilet seat, and the paper should be soft and thin like toilet paper, which can be discarded by washing. It is something. Therefore, he is very weak and it is difficult to take out such large sheets of tissue paper one by one from the storage box as needed.In particular, the sheet paper has a punched part in the center corresponding to the opening of the toilet seat. Since it is connected to a part of the sheet paper, when it is pulled out from the storage box, the punched part tends to break toward the outer edge of the sheet paper, making it unusable in many cases. It was extremely difficult to use and uneconomical, as it was often pulled out at the same time. Moreover, the large sheet paper was folded one by one and stored in a storage box like tissue paper, but it is a large thin paper, and on top of that, there is a punched out part in the center to allow it to hang inside the toilet bowl. It is difficult in practice to fold these sheets one by one, and it is also difficult to mechanize them.In the end, they must be folded by skilled hands, which has the disadvantage of very low productivity and high costs. Ta.

[Means to solve the problem]

The present invention addresses the above-mentioned problems and covers the toilet seat by reliably bringing out the sheet paper one by one onto the toilet seat by electric operation without manually pulling out the sheet paper covering the top surface of the toilet seat.
To provide a toilet seat equipped with a sheet paper supply device that allows a user to sit on the toilet seat and relieve himself with peace of mind from a sanitary perspective when using a Western-style toilet bowl.

[For use]

The present invention involves feeding a fixed amount of soft, thin sheet paper wound into a roll stored in a sheet paper supply device from a paper outlet of the supply device to the top surface of a toilet seat using an electrically driven paper feed roller. One side of the sheet paper in the length direction is held between the feed rollers, with the perforation that separates the first sheet of the fed sheet paper in the middle, and the other side is a plate that is swung by an electrically driven cam member. It is held between the shaped movable plate and the pressure receiving body, and then
The movable plate is further rotated by a predetermined angle in the direction of holding the sheet paper, and a large tension is applied to the sheet paper between the paper feed roller and the movable plate, so that the perforation of the sheet paper is removed at this point. The area near the toilet seat is pressed by the sharp breaking protrusion protruding from the pressure-receiving member, and a larger force is applied than other parts, and by successively tearing the perforations near the area where the pressing force is applied, the top surface of the toilet seat is removed. After breaking the sheet paper, while sitting on the toilet seat, connect the broken part of the sheet paper spread on the toilet seat with the movable plate and the pressure receiving member. The sheet paper is held between the toilet seats to prevent it from slipping off the toilet seat, and furthermore, when the sheet paper is removed from the toilet seat after using the toilet, the sheet paper is unclipped and dragged into the toilet bowl to be discharged, and the end of the movable plate The present invention is characterized in that the paper delivery port of the sheet paper supply device is closed at the section to prevent dirty water such as urine from entering the supply device and contaminating the interior of the supply device.

Reference numerals 52 and 53 indicate light-emitting and light-receiving elements for detecting the presence or absence of the sheet paper 40 that is attached to the feed path 42 slightly inward from the paper feed port 43 of the paper feed box 4 without hindering the feeding of the sheet paper 40; For example, the light of 52 is
It is reflected on a white paper such as the sheet paper 40 and detected by the light receiving element 53 (indicating the presence of the paper). When it matches the through hole 45 opened at the rear of the provided punched part (see Figure 3) 44,
(When a fixed amount of sheet paper 40 is fed to the toilet seat 3)
When the light from the light emitting element 52 passes through the through hole 45 and reaches the tongue piece 50a of the cover 50, the light is absorbed and detected by the light receiving element 53 because the tongue piece 50a is colored other than white, for example. As a result, the electric motor 8 of the paper feed roller 6 is stopped by a command signal from a control device (not shown), and the feeding of the sheet paper 40 is completed. Further, in FIG. 1, 54 is a power switch of the apparatus of the present invention, and 55 is a power lamp. Further, reference numeral 56 shown in FIG. 5 is an outside air intake port, and the outside air that has flowed into the paper feed box 4 by the cooling fans (not shown) of the electric motors 8 and 9 is discharged into the paper delivery path 42 through the circulation hole 57, and the sheet is The paper 40 is slightly raised in the delivery path 42 to prevent the sheet paper 40 from clogging during delivery. In the paper feeder 2 of the present invention, the operation of the electric motor 8.9 is all sequentially controlled by a control device (not shown) housed in the other extension 4b of the paper feed box 4. Next, the operation will be explained. When using the Western-style toilet l, the movable plate lO in the supply device 2 closes the paper delivery hole 43 at one end, as shown in FIG.
This prevents the paper from entering the paper delivery path 42. If you want to use Western-style toilet 1 now in this state, first:
Turn on the power switch 54. When the switch 54 is turned on, the lamp 55 lights up, the electric motor 9 is started, and the plate cam 1 is turned on.

When the movable plate IO stops in the state shown in FIG. 4, the electric t! 8 starts, and the sheet paper 40 is transferred to the feed path 42 while being held between the paper feed roller 6 and the presser roller 7.
The paper is sent out by aligning the inside with the paper delivery port 43. For this reason,
The rolled sheet paper 40 is returned to
The paper is led out from the paper outlet 43 of the paper feed box 4 onto the toilet seat 3. At this time, the light from the light emitting element 52 is transmitted to the sheet paper 4.
0 and detected by the light receiving element 53. Then, as shown in FIG. 3, when one sheet of sheet paper 40 is spread on the toilet seat 3, the sheet paper 40
The through hole 45 opened at the rear of the punched part 44 matches the light emitting element 52 provided inside the paper outlet 43, and the light from the light emitting element 52 passes through the through hole 45 and reaches the tongue piece 50a of the cover 50. Since it is absorbed by the light receiving element 53 and is not reflected,
Therefore, the detection signal from the light receiving element 53 is not input to the control device, and a command to stop the electric motor 8 is sent from the control device, the electric motor 8 is stopped, and feeding of the sheet paper 40 is stopped. At this time, the perforations 41 of the sheet paper 40 are connected to the break protrusion 30 and the paper feed roller 6.
It is set to be located between. When the feeding of the sheet paper 40 stops, the electric motor 9 is restarted by a command signal from a control device (not shown), and the plate cam 1 is restarted.
5 clockwise in FIG.
The movable plate 1O is rotated counterclockwise about the pivot shaft 11 in the opposite direction to the plate cam 15, as shown in FIG. Therefore, a part of the sheet paper 40 that remains in the paper delivery path 42 is removed from the plate cam 1 as shown in FIG.
5, the rotary plate 10 is lifted toward the pressure receiving body 21 by the ends of the six paper feed rollers, which rotate counterclockwise.
When the cushioning material a of the movable plate 10 comes into contact with the cushioning material of the pressure receiving body 21, the sheet paper 40 is held between the paper feed roller 6 and the movable plate IO. In this state, the movable plate 10 is further rotated by the rotation of the plate cam 15.
continues to rotate and presses the pressure receiving body 21 upwardly within the cylinder body 26 against the force of the compression spring 28. Therefore, a large tension is applied to the sheet paper 40 between one end of the movable plate 10 and the paper feed roller 6, and the movable plate 10 is rotated by the plate cam 15 to a position close to the maximum. When it moves, the bridge portion 22a of the hanging frame 22
A larger tensile force is applied to the portion of the sheet paper that contacts the breaking protrusion 30 provided on the sheet paper than the portion that does not make contact, and as a result, the perforations 41 near the portion of the sheet paper 40 that contacts the breaking protrusion 30 are , the sheet paper 40 cannot withstand the tension and is torn sequentially from that part, and one sheet of sheet paper 40 is broken from the perforation 41 as shown in FIG. When the sheet paper 40 is torn, the electric motor 9 driving the temporary cam I5 is temporarily stopped by a command signal from the control device. Therefore, as shown in FIG. 7, the torn sheet paper 40 is held between the movable plate 10 and the pressure receiving body 21, and the torn sheet paper 40 is not displaced from the toilet seat 3. After placing sheet paper 40 on the toilet seat 3 to prevent it from sliding down, the user sits on the toilet seat 3 via the sheet paper 40, hangs the punched part 44 into the toilet bowl l, submerges it in water, and then relieves himself. At this time, the sheet paper 40 is held between the movable plates 10 as described above, and even if the user moves his or her body slightly on the toilet seat 3, the sheet paper 40 will not shift. When the user leaves the toilet seat 3 after relieving himself, a seating detection sensor (not shown) attached to the toilet seat 3 detects this, and this detection signal is sent to the control device, which drives the plate cam 15 again. A command is sent to start the electric motor 9, and the movable plate 10 is rotated clockwise in FIG. 7, contrary to the above. i.e., movable play)1
Return 0 to its original position. As a result, the torn sheet paper 40 is released from being held between the movable plate 10 and the pressure receiving body 21, and at this point, when flushing water is allowed to flow into the toilet bowl 1, the punched portion 44 of the sheet paper 40 is removed from the toilet bowl 1. Since the toilet seat 3 is submerged in water, the main body of the sheet paper 40 spread on the toilet seat 3 is drawn into the toilet bowl 1 by the flushing water and is discharged together with the flushing water. On the other hand, plate cam 1
The movable plate 1 is rotating clockwise by the drive of 5.
0 continues to rotate even after being returned to the state parallel to the paper delivery path 42, as shown in FIG. 4, and as shown in FIG.
The movable plate 10 located on the paper outlet 43 side
When the drive of the temporary cam 15 is stopped by a command from the control device just before the other end of the paper outlet 43 closes, the movable plate 10 closes the paper outlet 43 as shown in the eighth section.
Stop with 3 closed. That is, it returns to its original position. After this, if you continue to use Western-style toilet 1,
By turning on the power switch 54 again, the sheet paper 40 can be drawn out to the required length from the paper feed box 4 as described above and automatically laid on the toilet bowl 3, allowing the user to keep the Western-style toilet bowl 1 sanitary. It can be used with peace of mind. Next, when replacing the sheet paper 40 or when a paper jam occurs in the paper feed box 4, remove the cover 50 from the paper feed box 4 as shown in FIG. When the member 20 is rotated in front of the toilet seat 3 (to the left in FIG. 9), the pressure receiving body 21 and the press roller 7 provided at the lower part of the hanging frame 22 can be pulled out in front of the paper feed box 4. If a paper jam occurs in this state, the presser roller 7 and paper feed roller 6 have been separated, so rewind the roll of sheet paper 40 a little and wrap the end around the presser roller and hang it on the hanging frame. By returning the body 22 to its original position, the sheet paper 40 can be easily re-cented. When replacing the sheet paper 40, the sheet paper holder 〇 can be easily removed from the support rods 24, 24'' by moving the support rod 24 to the left in FIG. In this state, a new sheet paper 40 can be set.Furthermore, when reusing the supply device 2, if the cover 50 is placed on the cover 50, the hanging frame member 20 will be received by the cover 50, and the sheet paper 40 will not break. , the sheet paper 4 is smoothly fed out without shaking during feeding.
It is possible to pay out 0.

【Effect of the invention】

Since the present invention is configured as described above, it has the following effects. (1) When cutting sheet paper, the present invention is configured so that a predetermined tension is applied to the sheet paper between a paper feed roller and a movable plate, and the sheet paper is torn from the perforation and broken. Since a cutter is not required to cut the sheet paper, the cutting mechanism for the sheet paper wound into a roll can be significantly simplified. (2) In addition to the role of holding the sheet paper between the pressure receiving body and applying tension, the movable plate can also serve as a feeding path for the sheet paper. When feeding sheet paper, there is no need for a special member to guide it to the paper feeding port, so paper can be fed smoothly to the toilet seat without causing any jams, and the structure of the sheet paper feeding device can be simplified. Combined with this, it is easy to operate and can be manufactured economically. (3) Furthermore, the present invention has a structure in which the sheet paper placed on the toilet seat is pressed and held by a movable plate until the user finishes sitting, so there is no possibility that the sheet paper will shift while the user is sitting. In addition to being hygienic, since the paper delivery port is closed by the movable plate when the toilet seat is not seated, sewage, etc. does not enter the paper feed box, making the sheet paper feeding device hygienic. can be retained.
