However, the holder of Patent Document 1 has a complicated mounting structure with respect to the lower surface of the lid, and is difficult to attach to an existing holder.
SUMMARY OF THE INVENTION An object of the present invention is to provide a paper holder having a simple structure that can be easily attached to an existing holder and can feed out the leading end of the paper with a simple operation.

In order to solve the above-mentioned problems, the invention of claim 1 in the paper holder of the present invention is a cylinder having a core receiving body provided on a roll support part protruding forward from a base part and having a cavity for suspension in the core receiving body. The roll paper wound around the core material can be suspended up and down via a roll loading section that can be suspended horizontally and parallel to the base section, and a pivot section provided on the base section or the roll support section, and at the tip section. In a paper holder provided with a paper cutting part capable of cutting the paper on the front side of the roll paper with a provided paper cutting blade, less resistance in the direction of feeding the leading end of the paper to the outer peripheral surface of the roll paper and before the roll feed unit having a spring for biasing the roll paper Previous respect inverse stop surface with the in the opposite direction with a check surface whose resistance is large Mounted so that it can always contact the rear side of the roll paper whose diameter is attenuated by the use of the paper, and comes into contact with the front side upper surface to the lower surface of the outer peripheral surface of the roll paper. The base or roll support part is provided with a roll pressing part that can be rotated while being supported by a receiving body to push up the roll paper.

  According to a second aspect of the present invention, in the above invention, the roll pressing portion is integrally formed with the paper cutting portion, and the roll pressing portion always contacts the front portion of the outer peripheral surface of the roll paper whose diameter is attenuated by the use of the paper. It is characterized by having a plate surface curved so as to be possible.

  According to a fourth aspect of the present invention, in the above invention, the non-return body having the non-return surface is formed of a deflected implanted fiber surface in which a contact surface to the loaded roll paper is inclined upward.

  The invention of claim 5 is characterized in that, in the above invention, a return spring is provided between the base of the paper cutting part and the paper cutting part to bias the paper cutting blade so as to return to the original position.

The paper holder of the present invention has the above-described configuration, and when the roll pressing portion is pushed by hand, the roll paper supported by the core receiving body is pushed up while rotating the check surface of the roll feeding portion upward.
And when the roll paper is released, the pressure is released and it falls with its own weight, but at that time the reverse surface of the roll feed part stops the rotation of the upper part of the roll paper in the backward direction, so the forward direction Falling while rotating.
And the leading edge of the roll paper is fed forward from the paper cutting blade, and the leading edge of the fed roll paper is within the range where it can be picked up with a finger. It becomes.
That is, the leading end of the roll paper can be pulled out by a simple operation of pressing the roll pressing portion.
And when the roll pressing part is pushed and released, the roll paper not only falls, but the roll paper can be positively pushed forward by a non-return surface that forwards the roll by the force of the spring. As a result, the feeding of the leading edge of the paper is ensured.

  In the invention of claim 2, the roll pressing portion is used integrally with the paper cutting portion, and the roll pressing portion is a front portion of the roll paper even if the curved plate surface is attenuated in diameter by the use of the paper. It is always possible to abut. For this reason, when the roll pressing part is pressed, the roll paper is reliably pushed up.

  In the invention of claim 4, when the non-return surface of the non-return body is a deflected implanted fiber surface, when the deflected implanted fiber surface inclined upward comes into contact with the rear surface of the roll paper, the deflection is performed when the roll paper is pushed up. The fiber is pushed up without resistance on the surface of the implanted fiber, and when the hand is released next time, the fiber in the deflected implanted fiber surface pierces the fiber of the paper and falls in the backward direction, so that the reverse rotation effect is enhanced. It is done.

  In the invention of claim 5, since a return spring is provided between the base of the paper cutting portion and the paper cutting portion so as to return the paper cutting portion to a horizontal position, the weight of the paper cutting portion is The load due to is reduced, and the pressure for the roll-out movement of the roll paper is reduced. For this reason, it is possible to prevent the roll paper from rotating backward without being obstructed by the weight of the paper cutting portion, and to reliably feed out the paper leading end portion.

It is a vertical side view which shows the use condition which sent out paper. It is a vertical side surface which shows the aspect which made the roll paper one point support in the upper part of the core support body.

Embodiments of the present invention will be described below.
The present invention is directed to roll paper having a relatively wide cavity as a core material. For example, toilet paper is a cylindrical core material having a cavity with a diameter of about 4 cm, and a strip-shaped paper with a width of about 11 cm is about 10 cm in outer diameter. It is intended for roll paper wound to a thickness of. The core member has a certain hardness that can hold the cylindrical shape without being easily crushed even when pressed with a finger.

As shown in FIGS. 1 and 2, the paper holder of the present invention includes a roll loading unit 2 that holds the roll paper R and a paper cutting unit 5 that cuts the leading end of the roll paper R.
The roll loading section 2 has left and right roll support sections 3 projecting from the front surface 1a of an upright plate-like base 1 for mounting on the wall surface of the toilet, and a width of about 4 cm between the roll support sections 3 and a width of about 2 cm. A core support 4 having a length of about 1 cm is provided.

  In the present embodiment, the core material S of the roll paper R is formed between the core support body 4 and a play space which is four times as large as that of the core support body 4, and the roll paper R is placed on the core support body 4. Although the suspended state is illustrated, the relationship between the cavity K and the core receiving body 4 is that the roll paper R suspended around the contact portion j that is the upper part of the core receiving body 4 is used. As shown in FIG. 8, the center of gravity c1 of the roll paper R is rotated to c2 so that the center of gravity can be pushed up to a certain height.

The core receiving body 4 is capable of projecting so as to face the roll support portions 3 on both sides so that the roll paper R in which the paper P is wound around the cylindrical core material S can be held in parallel and horizontally with the base portion 1. Provide.
In addition, the roll support part 3 and the core support body 4 can be combined with different parts or integrated.

In FIG. 1, the base of the core receiving body 4 is pivotally supported at the lower part in the core receiving body folding storage groove 15, and the core receiving body 4 is connected to the core receiving body folding storage groove 15 so as to be folded upward, The core receiving body 4 shows a mode of a structure that stops in a horizontal state so as not to be lowered.
In this embodiment, when the roll paper R is inserted from the bottom, the core receiver 4 is folded upward, the side surface of the roll paper R slides upward, and the core material S passes through the tip of the core receiver 4. When the roll paper R is lowered, the core receiving body 4 enters the cylinder of the core material S. When the roll paper R is lowered, the core receiving body 4 becomes horizontal and stops, and the core material S of the roll paper R rides on the protruding corners 4a and 4b of the core receiving body 4 so that the roll paper R is horizontal. It is a mechanism to be hung. At that time, since the core receiving body 4 is smaller than the core material S, a wide cavity K is formed below the core receiving body 4 in the core material S.

The paper cutting part 5 is formed in a plate shape that is curved so that the front part swells upward, and pivotally supports the base part 5b via a pivotal support part 7 provided on the roll support part 3 so as to be vertically movable. In FIG. 1, reference numeral 7 a denotes a pivot shaft 7 a for pivotally supporting the paper cutting portion 5 on the roll support portion 3.
And the paper cutting blade 5a is provided in the front-end | tip part of the said paper cutting part 5. As shown in FIG.
As shown in FIG. 2, the paper cutting blade 5a hits the paper P1 on the front side of the roll paper R loaded in the roll loading unit 2, and pushes the paper P with the leading end pushed up against the paper cutting unit 5 A sharp paper cutting blade 5a is integrally formed at the tip of the paper cutting portion 5 so that the paper P is cut when pulled toward the head.

The paper cutting blade 5a may be formed in a certain width, and may be retrofitted with an adhesive or the like directly on the tip of the upper lid of the existing toilet paper holder. By adjusting the width and the mounting direction, it is possible to form the tip of the paper cutting part 5 in an arbitrarily deep curved state.
In addition, it is also possible to provide the pivot portion 7 that pivotally supports the paper cutting portion 5 with respect to the base portion 1 in addition to the roll support portion 3.

Further, as shown in FIG. 4, a roll feeding portion 8 that can always come into contact with the rear side surface of the roll paper R whose diameter is attenuated by using the paper P is mounted on the front surface 1 a of the base portion 1.
The roll feeding portion 8 has a non-return check in which the upper portion for feeding the leading end portion P1 of the paper P rotates less forward with respect to the outer peripheral surface of the roll paper R in the direction in which the upper portion rotates and in the opposite direction. A check body 9 having a surface 9a is provided.

The non-return surface 9a of the non-return body 9 can be an embedding surface of the hard thread-like deflected implanted fiber surface embedding 13 in which the contact surface 9b to the loaded roll paper R is inclined upward.
The deflection-implanted fiber surface 13 is formed by implanting hard fibers of a certain length made of a linear synthetic resin, with all of them being densely inclined at equal intervals in the same direction. The deflection-implanted fiber surface 13 rotates smoothly with little resistance when the surface is mixed in the direction in which the fiber is tilted, but when mixed in the opposite direction, the fiber is caught so as to pierce. For this reason, the non-return effect with respect to the surface of the paper P is exhibited.

Further, in order to always bring the check surface 9a of the roll feeding portion 8 into contact with the rear side surface of the roll paper R, as shown in FIG. 2, the roll paper R is moved forward with respect to the check surface 9a. A plate-like spring 10 for biasing is provided.
As shown in FIG. 2, the spring 10 is applied to the roll paper R from the lower side of the front surface 1a of the base 1 so as not to obstruct loading of the new roll paper R between the roll support parts 3 from below. It is preferable to provide it facing diagonally upward.
For this reason, the spring 10 has a base 10b fixed to the front surface 1a of the base 1 with a leaf spring fixing screw 11, and as shown in FIG. 4, a check surface of the check body 9 provided on the tip 10a side. The length 9a is determined so as to reach a range in which the diameter of the roll P can be always brought into contact with the rear side of the roll paper R whose diameter is attenuated by the use of the paper P, and the roll paper R is urged in a direction to push it forward. Fix it.

In addition, a in FIG. 6 is the length from the base part 10b of the said spring 10 to the front-end | tip part 10a, and a dashed-dotted line shows the locus | trajectory which the front-end | tip part 10a can move. The length to the tip portion 10a is determined so that the locus exceeds the core support 4.
The spring 10 is a spring 10 for always bringing the check surface 9a into contact with the roll paper R, and a plate-like soft spring 10 made of synthetic resin can be used.
If the spring 10 is too strong, the loaded roll paper R is always strongly pushed forward, and the core material S is lifted away from the front corner 4a of the core receiving body 4, and will be described later. This is not preferable because the roll paper R may be pushed up by the roll pressing unit 6.
In addition to the form using the spring 10, a plate is pivotally supported at the lower portion of the base portion 1 so as to be freely rotatable, or the plate is hung freely on the base portion 1 or the roll support portion 3 and provided on the front surface of the plate. Further, a configuration in which the check surface 9a of the check body 9 is always inclined so as to ride on the rear upper part of the roll paper R by its own weight is also possible. Even in this configuration, the check surface 9a of the check body 9 can be kept in contact with the roll paper R at all times.

Further, a roll pressing portion 6 is provided that allows the roll paper R to be pushed up by being brought into contact with the lower surface from the front upper surface of the roll paper R.
The roll pressing portion 6 is shown in a form that is used integrally with the paper cutting portion 5 in each drawing.
The roll pressing portion 6 shown in FIG. 4 is greatly curved so that the front end side plate surface lower portion 12a swells upward so that the roll pressing portion 6 can always come into contact with the front portion of the roll paper R having a small diameter and attenuated by the use of the paper P. The aspect of the plate surface 12 is shown.

When the roll pressing part 6 is provided separately from the paper cutting part 5, the paper cutting part 5 is provided so as to cover the roll paper R as shown in FIG. 2, and the roll pressing part 6 is provided to the roll paper R. The base portion 1 or the roll support portion 3 can be provided so as to be able to come into contact with a portion from the front upper surface to the lower surface of the outer peripheral surface.
For example, although not shown, the roll pressing part 6 is provided with a pivotal support part at the lower part of the roll support part 3 so as to be capable of swinging up and down, and the roll pressing part 6 is pushed up from below by hand to raise the roll paper. It becomes possible to abut against the lower surface of the outer peripheral surface of R and push up that portion.

Also, a return spring 14 is provided between the base 5b of the paper cutting part 5 and the paper cutting part, as shown in FIG. 5, for biasing the paper cutting blade 5a so as to surely return to the original position. Can do.
Since the roll paper R used in the present invention is extremely light, it is difficult to smoothly rotate the upper part of the roll paper R forward by inhibiting the normal fall of the roll paper R when the load of the paper cutting part 5 is large. There is a risk of becoming. For this reason, it is preferable to provide a return spring 14 that is urged to a strength that ensures that the paper cutting blade 5a is positioned in the original position against the load of the paper cutting portion 5.

  Next, a mechanism for feeding the leading end of the roll paper R loaded in the paper holder of the present invention will be described.

The roll paper R held by the paper holder is loaded in a state of being hung on the left and right core receiving bodies 4 shown in FIG.
In this state, the position of the center of gravity of the roll paper R is at the position c in FIG.
The paper P is used after being pulled out from the roll paper R, and as shown in FIG. 2, the tip portion P1 of the paper P is slightly exposed as a whole as shown in FIG. It becomes impossible to pick the tip P1 of the paper with a finger.
In the core material S of the roll paper R suspended from the core receiver 4, there is a wide cavity K under the core receiver 4, and the roll paper R is its own weight and the core material S is the core receiver 4. The protruding corners 4a and 4b are suspended in a state in which the protruding portions 4a and 4b of the core receiving body 4 and the front contact portion x and the rear contact portion y of the core material S are on the roll. When the paper R is pushed back and forth, it comes into a state of swinging with a constant width with the contact portions x and y as fulcrums.

FIG. 6 shows a state in which the roll paper R is suspended from the core support 4 by its own weight and held by the paper holder of the present invention.
In this state, the roll paper R is suspended from the front corner 4a of the core receiver 4 and the rear corner 4b of the rear of the core receiver 4.
Then, the paper cutting blade 5a of the paper cutting part 5 gets lightly on the front side of the roll paper R, and comes into contact with the check surface 9a of the roll pushing part 8 so as to press behind the roll paper R.
At this time, the center of gravity of the roll paper R is at the position c1 in FIG. 6. Note that b in FIG. 6 indicates the length from the pivotal support portion 7 of the paper cutting portion 5 to the paper cutting blade 5a at the tip portion. The alternate long and short dash line indicates a trajectory that allows the paper cutting blade 5a and the roll pressing portion 6 integrated with the paper cutting blade 5a to move by rotating the pivot 7 to the center of gravity.

Next, when the paper cutting unit 5 is manually pushed down from above, as shown in FIG. 6, the roll pressing unit 6 at the tip of the paper cutting unit 5 has a circular shape in which the front upper portion of the roll paper R is indicated by a one-dot chain line with a radius b. Press down along the trajectory.
Then, the roll paper R is restrained by the front corner 4a of the core receiver 4 and causes a circular motion with the center 4a as the center of gravity. The roll paper R rotates while pushing the check surface 9a of the roll extruding part 8 that is separated from the rear corner 4b of the body 4 and contacts the back of the roll paper R, and the roll paper R is pushed upward by the white arrow.
At this time, the center of gravity of the roll paper R has moved from the position c1 in FIG. 6 to the position c2.

At this time, for example, as shown in FIG. 8, when the roll pressing part 6 provided at the tip of the paper cutting part 5 pushes down the front upper part of the roll paper R, the core receiving body 4 of the core material S of the roll paper R When the contact portion j with the uppermost portion moves to the contact portion k above it, the roll pressing portion 6 can be lowered to the position P1 in the figure.
As a result, the center of gravity of the roll paper R moves from the position c1 in FIG. 8 to the position c2 obliquely above.
At this time, the roll paper R whose front side is pushed down by the roll pressing portion 6 rotates at the contact portion with the check surface 9a with the contact portion j of the core receiving body 4 as a fulcrum, and then the check surface 9a. It is presumed that the motor rotates in the clockwise direction in FIG.

Next, when the hand is released from the paper cutting portion 5, the core support 4 moves in the cavity K by the height difference indicated by the white arrow pointing downward with the dead weight of the roll paper R as shown in FIG. While falling.
At the time of the fall, the non-rotating surface 9a of the non-returning body 9 provided on the roll pushing portion 8 becomes a resistance, and the roll paper R is prevented from rotating counterclockwise in FIG. 3 is rotated, and as shown in FIG. 3, the roll paper P has an angle at which the front side of the roll paper R is in contact with the paper cutting blade 5a from the position of the contact portion P2 with the paper cutting blade 5a. It is estimated that the leading end P1 of the roll paper P is fed from the leading end of the paper cutting unit 5 by α rotation.

That is, the center of gravity of the roll paper R is lowered from the position c2 in FIG. 7 to the position c3 that is obliquely downward as indicated by the obliquely downward arrow. As a result, the leading end portion P1 of the roll paper P is sent out from the paper cutting blade 5a to a certain length, that is, from the paper cutting blade 5a indicated by a thick line in FIG.
At this time, in the embodiment in which the spring 10 is provided on the non-return body 9, the non-return surface 9a of the non-return body 9 positively pushes the roll paper R forward so that the roll paper P can be reliably removed from the paper cutting blade 5a. It becomes possible to send out the front-end | tip part P1 by fixed length.
When the operation of pushing or hitting the roll pressing portion 6 by hand as described above is repeated several times, as shown by a one-dot chain line in FIG. 3, the leading end portion P3 of the roll paper P hangs down in front of the roll paper R, It becomes possible to pick a part with a finger.

  In addition, when the non-return body 9 of the roll pushing portion 8 is provided so as to contact the front side rather than the rear side of the outer peripheral surface of the roll paper R, the roll paper R is forwardly moved upward when the roll paper R is dropped. Rotation is not obtained, and the leading end P1 of the roll paper P is not sent out before the paper cutting blade 5a or is returned to the back, which is not preferable.

  The paper holder of the present invention is mainly for toilet paper, but it can also be used for a hand-wiping holder that uses roll paper in which paper is wound around a cylindrical core material.
