Description

  The present invention relates to a toilet paper holder for holding roll-wound toilet paper in a toilet for use.

  Toilet paper used in daily life is almost roll-wrapped toilet paper, and the roll-shaped paper can be used by pulling out (feeding out) the strip-like paper to a desired length for use. The toilet paper is placed in the toilet so that it can be replenished and replaced. On the other hand, because of the growing hygiene sensation, even for toilets that are kept clean, the strip-shaped paper of the desired length can be pulled out and separated from the roll-like toilet paper without touching the tray paper holder directly. Strong desire to do.

  In view of the present situation and demand, as a conventional toilet paper holder of this type, a toilet paper feeding outlet is provided in the holder housing, and the toilet paper feeding means including a feeding roller and an auxiliary roller that are in contact with each other in parallel is described above. A cutter means for cutting toilet paper is provided on the outside of the above-described outlet and provided on the inside of the outlet, and the leading end of the roll-like toilet paper is passed between the feeding roller and the auxiliary roller from the toilet paper outlet. The toilet paper that is sandwiched between the feeding roller and the auxiliary roller is fed out from the toilet paper holder by operating the push-button for operation. Switch for the above drive motor Japanese Patent Laid-Open No. 9-75258 proposes a method in which the length of the toilet paper is adjusted by changing the driving time of the paper and the leading end of the toilet paper is cut by the cutter means. reference). However, in such a toilet paper holder, the end of the roll-like toilet paper must be led out toward the tocutter means between the feeding roller and the auxiliary roller, so that the toilet paper replenishment and replacement work is extremely difficult. In addition to being cumbersome and inconvenient, it also requires a cutter mechanism, and there is a drawback that it is necessary to touch a push button switch for operation that forms part of a toilet paper holder that is worrisome as a hygiene sensation.

As another conventional example of this type of toilet paper holder, a drive roller and an idle roller that are in contact with each other in parallel as in the conventional example, and a cutter for cutting the toilet paper are provided. The tip of the paper is guided to the cutter through the drive roller and idle roller, and the drive roller is rotated by the drive motor so that the toilet paper is fed out of the toilet paper holder, and the time taken to bring the hand close to the proximity sensor is adjusted. There is also proposed a technique in which the driving time of the driving motor is changed to adjust the length of the toilet paper that is fed, and the leading end of the toilet paper that has been fed is cut by the cutter means (Japanese Patent Laid-Open No. Hei. See 10-5149 . However, in such a toilet paper holder, it is not necessary to directly touch the toilet paper holder for the operation of using the toilet paper holder, but the tip of the arrow roll rolled toilet paper is moved to the drive roller (rolling roller). ) And the idle roller (auxiliary roller) must be guided toward the cutter, so that the toilet paper replenishment and replacement operation is extremely complicated and troublesome, and the cutter mechanism has the same drawback.

  The present invention improves the above-described disadvantages of the conventional toilet paper holder, and the left and right side walls that rotatably hold the axial center of the roll-like toilet paper and the rear wall that connects both side walls are formed. Based on an existing toilet paper holder with an extremely simple structure consisting of a holder frame and a paper cutting plate that is rotatably supported along the rear wall of the holder frame and covers the upper side of the roll-wrapped toilet paper This is improved, and when using roll paper toilet paper, the front end of the toilet paper is fed out to the desired length without touching the toilet paper holder, and the drawn toilet paper is grasped by hand. Let's make it easy and reliable to cut out the required amount of toilet paper It is intended to.

In order to solve the above-described problems, the present invention provides a holder frame in which left and right side walls that rotatably hold the axial center portion of a roll-like toilet paper and rear walls that connect both side walls are formed, and the holder In a toilet paper holder that is supported rotatably along the rear wall of the frame and covers the upper part of the outer peripheral surface of the toilet paper, a roll-like toilet that is rotatably held between the left and right side walls A paper feeding rotary wheel that rotates while contacting the outer peripheral surface of the paper and feeds the end of the toilet paper out of the toilet paper holder, a motor that rotationally drives the paper feeding rotary wheel, a power supply device for the motor, User's hand of operating the toilet paper holder by hand to use the toilet paper A proximity sensor switch which opens and closes an electrical circuit by detecting the approaching state provided, constituting a toilet paper holder by connecting the motor to the power supply device via the proximity sensor switch.

Also, when the paper feeding rotary wheel is rotated, the belt-shaped toilet paper is reliably fed out, and when the paper feeding rotary wheel is stationary, the outer peripheral surface of the toilet paper is pressed so that the toilet paper does not rotate in preparation for cutting out the toilet paper. In order to do this, a paper hole is formed in the paper cutting plate that covers the upper part of the outer peripheral surface of the roll-shaped toilet paper, and a paper feeding rotary wheel is attached to the paper cutting plate and is allowed to look through the window hole. A rotating wheel is brought into contact with the outer peripheral surface of the toilet paper. Further, a motor for rotating the paper feeding rotary wheel is placed on the paper cutting plate and connected to the rotary shaft of the paper feeding rotary wheel.

In addition, a sufficient pressing force is applied to the outer peripheral surface of the toilet paper so that the belt-shaped toilet paper is reliably fed when the paper feeding rotary wheel is rotated and the toilet paper does not rotate in preparation for cutting the toilet paper when the paper feeding rotary wheel is stationary. A motor for driving the paper feed rotary wheel to rotate and a power supply device for the motor while attaching the paper feed rotary wheel to the paper cutting plate and making it look through the window hole to contact the outer peripheral surface of the toilet paper Is placed on a paper cutting board.

  Also, in order to allow the user of the toilet paper to take out and cut out the toilet paper of a desired length without directly touching the toilet paper holder, a roll wound held rotatably between the left and right side walls. A paper feeding rotary wheel that rotates while contacting the outer peripheral surface of the toilet paper and feeds the tip of the toilet paper out of the toilet paper holder, a motor that rotationally drives the paper feeding rotary wheel, and a power supply device for the motor And a proximity sensor switch that opens and closes an electric circuit by detecting an approaching state of a user's operating hand to manually operate the toilet paper holder in order to use the toilet paper, and the proximity sensor switch is connected to the holder frame Or attach it to a paper cutting board, The serial motor connected to the power supply device through the proximity sensor switches constituting the toilet paper holder.

  According to the toilet paper holder according to the present invention, the paper feeding rotary wheel is brought into direct contact with the upper part of the outer peripheral surface of the roll-like toilet paper so that the belt-like toilet paper is fed out and stopped. It is not necessary to provide toilet paper feeding means that requires relatively high-precision processing as seen in the conventional toilet paper holder, that is, toilet paper feeding means consisting of a feeding roller and an auxiliary roller that are in contact with each other in parallel. Since it is not necessary to sandwich the tip of the toilet paper between the feeding roller and the auxiliary roller, it is very easy and easy to attach the toilet paper to the toilet paper holder and replace the toilet paper. . Further, in the toilet paper holder according to the present invention, a motor for driving the paper feeding rotary wheel to rotate and a power supply device for the motor are placed on a paper cutting plate covering the upper peripheral surface of the roll-like toilet paper. Sufficient pressing force is applied to the outer peripheral surface of the roll-shaped toilet paper, and the friction effect between the outer peripheral surface of the roll-shaped toilet paper and the paper feeding rotating wheel is increased. As a result, when the paper feed rotary wheel rotates, the paper feed rotary wheel reliably catches the tip of the toilet paper and reliably feeds it out of the holder frame. When the paper feed rotary wheel stops, the roll-like toilet paper rotates. Can be suppressed. If the toilet paper tip, which has already been drawn out to the required length, is pulled up with the hand while the feeding rotary wheel is stopped, the tip of the toilet paper is separated by the paper cutting edge at the front edge of the paper cutting board. Therefore, it is not necessary to separately provide a cutter means having a complicated structure as found in the conventional toilet paper holder. The user who operates the toilet paper holder approaches the proximity sensor switch attached to the toilet paper holder and adjusts the proximity time so that the toilet of the desired length can be obtained without directly touching the toilet paper holder. The paper can be fed out and easily cut out, and the cleanliness and hygiene of the toilet paper user can be satisfied.

The best mode of the toilet paper holder according to the present invention is such that the left and right side walls rotatably holding the axial center portion of the roll-like toilet paper, the rear wall connecting the both side walls, and the rear edge of the rear wall A toilet paper holder provided with a paper cutting plate that is rotatably supported along the outer peripheral surface of the toilet paper, and forms a window hole in the paper cutting plate that covers the upper peripheral surface of the toilet paper, A paper feed rotating wheel that rotates while contacting the outer peripheral surface of a roll-like toilet paper that is rotatably held between the left and right side walls and feeds the front end of the toilet paper out of the toilet paper holder is used as the paper cutting plate. Attach and rotate the paper feeding rotating wheel through the window hole of the paper cutting plate. A motor for rotating the paper feeding rotary wheel is placed on the paper cutting plate and connected to the rotary shaft of the paper feeding rotary wheel, and the power supply device for the motor is also connected to the paper cutting plate. A proximity sensor switch that opens and closes an electric circuit by sensing the approaching state of a user operating the toilet paper holder by hand to use the toilet paper is mounted on the outside of the side wall or the paper cutting board. The toilet paper holder is attached to the power supply device and connected to the power supply device via the proximity sensor switch.

  An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a toilet paper holder according to the present invention. 2 is an electrical circuit diagram of the toilet paper holder, FIG. 3 is a plan view of the toilet paper holder, and FIG. 4 is a cross-sectional view of the toilet paper holder along the line A-A ′ of FIG. 3.

  In the figure, H is a holder frame, which is composed of a right side wall 1, a left side wall 2, and a rear wall 3 connecting both side walls 1 and 2, between the right and left side walls 1 and 2. The axial center Pa of the toilet paper P is rotatably held. Reference numeral 4 denotes a paper cutting plate, which is attached to the holder frame H so that the rear edge 4a of the paper cutting plate 4 can rotate from the rear wall 3 of the holder frame H, and the toilet paper P is attached to the holder frame H. In the held state, the paper cutting plate 4 covers the upper part of the outer peripheral surface of the toilet paper P, and the front edge thereof is a paper cutting edge 4b when the toilet paper P is cut off. Note that a toilet paper holder having an extremely simple structure including the holder frame H and the paper cutting plate 4 as described above has been widely used.

  A window hole 4c is further formed in the paper cutting plate 4 described above. Reference numeral 5 denotes a paper feeding rotary wheel. The paper feeding rotary wheel 5 is rotatably attached to the paper cutting plate 4 and is seen through the window hole 4c, and is a roll-like toilet that is rotatably held between the side walls 2 and 3. It is made to contact the outer peripheral surface of the paper P. Accordingly, the paper feed rotating wheel 5 rotates while contacting the outer peripheral surface of the toilet paper P, whereby the front end portion Pb of the toilet paper P is sent out from the holder H. Further, a friction material 5a such as a rubber material is covered on the outer peripheral surface of the paper feeding rotating wheel 5. The friction material 5a is added to prevent slippage between the outer peripheral surface of the toilet paper P and the paper feeding rotary wheel 5. By providing the friction material 5a, the toilet 5 is rotated when the paper feeding rotary wheel 5 rotates. The front end portion Pb of the toilet paper P can be more reliably fed out by closely grasping the surface of the paper P, and when the paper feeding rotary wheel 5 is in a stationary state, a cutting force is applied to the front end portion 5b of the toilet paper P. However, it is possible to apply a large restraining force to the toilet paper P so that the tip end portion Pb of the toilet paper P is not pulled out carelessly.

  Reference numeral 6 denotes a motor that rotates the paper feeding rotary wheel 5, and the motor 6 is placed on the paper cutting plate 4 and is connected to a rotating shaft of the paper feeding rotary wheel 5 via a reduction gear group (gear box) 7. It is connected to. Reference numeral 8 denotes a power supply device for the motor 7, and the power supply device 8 is also placed on the paper cutting plate 4. A proximity sensor switch 9 is mounted on the side wall 2 of the holder H. The proximity sensor switch 9 includes a proximity sensing unit 9a. When a user who wants to operate the toilet paper holder H in order to use toilet paper, his / her operation hand (palm) is sufficiently close to the proximity sensing unit 9a. The electrical contact is turned on, and the electrical contact is turned off when the operation tip is moved away from the proximity sensing unit 9a. The motor 6 is connected to a power supply device 8 via a proximity sensor switch 9 as shown in FIG. The power supply device 8 in this embodiment is a device that is connected to the commercial power supply E, converts the voltage AC100V to DC3.0V and supplies it to the motor 6, but a power supply suitable for the operation of the motor 6 is close at hand. For example, the power supply device 8 as described above may be omitted, and the motor 6 may be connected to the compatible power supply via the proximity sensor switch 9. Then, by placing the motor 6 and the power supply device 8 on the paper cutting plate 4 as described above, the weight of the motor 6 and the power supply device 8 is applied to the roll-like toilet paper P via the paper feed rotating wheel 5. Since the toilet paper P is pressed, the rotation stopping force against the toilet paper P when the paper feed rotating wheel 5 is stationary is further increased.

When using the toilet paper holder having the above-described configuration according to the present invention, the user brings the operating tip close to the proximity sensing portion 9a of the proximity sensor switch 9, whereby the motor 6 is activated and the paper feeding rotary wheel 5 is slowed down. The front end portion Pb of the toilet paper P that rotates and is in contact with the paper feeding rotating wheel 5 is gradually fed out from the holder frame H.
When the distal end portion Pb of the toilet paper P is drawn out by a desired length, when the operating hand is moved away from the proximity detecting portion 9a of the proximity sensor switch 9, the motor 6 and the paper feeding rotating wheel 5 are stopped and the toilet is stopped. The feeding of the front end portion Pb of the paper P is stopped, and the rotation of the roll-like toilet paper is stopped. In this restrained state, the front end portion Pb of the toilet paper that has been drawn out is held by hand and pulled up above the paper cutting plate 4, so that the front end portion Pb of the toilet paper is removed from the paper cutting plate 4. It can be cut along the edge 4b. Therefore, the user of the toilet paper does not have to touch the toilet paper holder directly from the leading end of the toilet paper until it is cut off, and the cleanliness is satisfied.

  The toilet paper holder according to the present invention can be easily installed and used regardless of whether it is for home use, for office use, or for public facilities, and can meet a wide range of general demand.
