Description

The present invention relates to a roll paper holder, more specifically, even when the roll paper is sequentially pulled out from the holder body in which the upper surface is opened and the roll paper body is housed therein, and the roll paper remains in the roll paper body, the roll is rolled. Regarding a roll paper holder for toilet paper that allows the paper to be easily pulled out.

Roll paper for toilet paper generally has a form in which the roll paper is wound around a core paper cylinder (hereinafter, the form in which the roll paper is wound is referred to as a "roll paper body"). ..
When using this roll paper, the user first sets the roll paper body in the roll paper holder.

Usually, the roll paper holder includes a main body back plate that is attached to a wall and a holder main body that extends forward from both sides of the main body back plate and supports a mandrel support side plate that supports the roll paper main body via a mandrel. In addition to being freely openable and closable on the front side with the upper part of the back plate of the main body as an axis, many are equipped with a lid used as a plate for cutting roll paper.
In many cases, a cutting blade is formed at the tip of the lid.

In such a general roll paper holder, when setting the roll paper body, first hold the roll paper body with one hand and lift the lid of the roll paper holder with the other hand to lift the roll paper. The roll paper body is set in the roll paper holder by inserting the core of the main body into the mandrel and hanging the mandrel over the side plate for supporting the mandrel.
When pulling out and cutting the roll paper during use, first lift the lid with one hand so that the tip of the roll can be pulled out, and then pull out the tip of the roll with both hands as much as the user needs. Pull out with. Subsequently, the lid is pressed against the roll paper body with one hand, and the roll paper is pressed against the cutting blade at the tip of the lid with the other hand and pulled downward to cut out the required amount of roll paper. ..

However, in the roll paper holder having the above configuration, when setting the roll paper body, after lifting the lid of the roll paper holder, the roll paper body is inserted into the mandrel of the roll paper holder, and the mandrel is supported by the mandrel. Work such as hanging over the side plate is required.
In addition, when using, the lid is lifted with one hand to pull out the roll paper, then the lid is held with one hand and the required amount of roll paper is cut off with the other hand, which is troublesome. And other issues have arisen.

Therefore, in order to solve the above problems, a roll paper holder without a lid has been proposed for the roll paper holder having the above configuration (see, for example, Patent Document 1).
The roll paper holder disclosed in Patent Document 1 is configured so that the drawer end portion of the roll paper can be easily guided to the drawer outlet and set, and can be smoothly pulled out when the paper is pulled out. There is.
That is, the mounting portion of the roll paper holder is composed of a fixed portion fixed along the wall surface, a descending portion that is inclined forward from the fixed portion, and an ascending portion that is continuous with the descending portion. The roll paper is placed on the placement part with the axis lying down.

Further, a roll paper holder which can be used without touching the holder and whose roll can be easily replaced has also been proposed (see, for example, Patent Document 2).
In the roll paper holder disclosed in Patent Document 2, toilet paper is placed in a holder body having a substantially J-shaped cross section, and the holder body surrounds the roll and hits the front side of the roll. It is configured to have a frame-shaped holding frame in contact with it.

Japanese Unexamined Patent Publication No. 2011-19595 Japanese Patent Application No. 9-201307

However, in the roll paper holder disclosed in Patent Document 1, in order to set the roll paper, the roll paper is composed of a fixing portion, a lowering portion, and an ascending portion in a state where the axis is laid down. Since it is only necessary to place the paper on the placed portion, the setting work is easy, but the following problems have arisen regarding the drawing out of the paper.
That is, the paper is pulled out from the outlet formed at the boundary between the lowering portion and the rising portion, and after the roll paper is set, the use is started and a predetermined amount of paper is pulled out. The roll paper becomes lighter when the remaining amount is reduced, that is, when the outer diameter of the roll paper becomes smaller.
Therefore, when the paper is pulled out to be pressed against the cutting blade in order to cut it at a predetermined position, the lightened roll paper also rotates at the same time, so that the paper is pulled out more than necessary and becomes a double state, and at a fixed position. Since it is difficult to cut, the user has to hold down the remaining roll paper with one hand after all, and there is a problem that the work is troublesome.

Further, in the roll paper holder disclosed in Patent Document 2, a presser frame for enclosing the roll is provided in the holder body, and the presser frame is configured to press the outer peripheral surface of the toilet paper. Its tip is formed in a shape that allows it to rotate along a J-shaped curved bottom surface with the support shaft at the top of the holder body as a fulcrum.

Therefore, the length from the support shaft to the tip of the holding frame needs to be long enough to hold the outer peripheral surface of the unused toilet paper housed in the holder body. Further, since the presser frame is made of metal and is formed in a U shape by plate members having a predetermined thickness and a predetermined width, the total weight of the presser frame becomes considerably heavy.
When the paper is pulled out while the outer circumference of the toilet paper housed in the holder body is pressed by the holding frame as described above, the weight of the toilet paper is also a predetermined weight at the initial stage of use, and the toilet paper is also heavy. Even if a part of the outer circumference of the toilet paper is in contact with the inner surface of the holder body on the wall mounting portion side and the tip of the holding frame is pressing the outer circumference of the toilet paper with the contact point, the paper can be easily pulled out.

However, when a predetermined amount of paper is pulled out, the outer diameter of the toilet paper becomes smaller, and the weight becomes lighter, it becomes impossible to counter the pressing force of the pressing frame. On the other hand, since the holding frame is heavy, it rotates to the curved bottom surface with the support shaft as a fulcrum and stays at that position.
Then, due to the rotation of the holding frame, the lightened toilet paper is pushed by the contact points of the holding frame and moves along the curved bottom surface.

The paper to be pulled out is guided to the cutting blade side through the gap between the tip of the holding frame and the curved bottom surface as described above, but the pressing is performed on the entire outer peripheral surface of the tip of the holding frame on the curved bottom surface. Since it is pulled out in the state of being pulled out, there is a problem that the frictional force increases and it is difficult to pull out easily.

Further, for example, when pulling out the perforated paper, the perforation may be caught on the corner of the outer surface of the tip of the holding frame, and in that case, the drawn paper is torn at the curved bottom surface. The tip of the paper to be pulled out next stays there.
Then, the tip of the holding frame must be pushed up to the upper side of the holder body, and the tip of the paper to be pulled out next must be taken out from the curved bottom surface, which is troublesome and pulls out the roll paper. There is a problem that it is not easy.

(Purpose of the present invention)
An object of the present invention has been proposed to solve each of the above problems, and even when the roll paper of the roll paper body housed in the holder body is pulled out and the roll paper remains low in the roll paper body. The present invention is to provide a roll paper holder capable of easily pulling out the roll paper without pressing the roll paper body.

In order to achieve the above object, the roll paper holder according to the present invention includes a holder body in which the back surface portion of the main body is attached to the wall body, the upper surface portion is opened, and the roll paper main body is rotatably held inside. A roll paper holder provided with a roll paper cutting mechanism for cutting the roll paper drawn from the holder body.
The holder main body has a bottom surface portion extending from the lower end portion of the back surface portion of the main body toward the roll paper drawer side.
A roll paper drawer guide portion for guiding the drawer of the roll paper is formed at the drawer side tip of the bottom surface portion.
A roll paper pressing device that presses the roll paper body while allowing the roll paper body to rotate is provided on the back surface of the main body.
When the roll paper main body housed in the holder main body is unused, the roll paper presser device is located at a position longer than the distance between the back surface of the main body and the radial center of the roll paper main body. Roll paper pressing mechanism that presses the outer peripheral surface of
A pressing mechanism support arm whose tip portion rotatably supports the roll paper pressing mechanism is provided.
The pressing mechanism support arm is characterized in that its base end portion is rotatably provided on the back surface portion of the main body .

According to the roll paper holder of the present invention, when the roll paper is pulled out from the roll paper main body housed in the holder main body, the pressing mechanism of the roll paper pressing device allows the roll paper main body to rotate while allowing the roll paper to rotate. Since the outer circumference of the main body is pressed, the roll paper of the roll paper main body housed in the holder main body is pulled out, and even if the roll paper remains low in the roll paper main body, the roll paper can be easily made without pressing the roll paper main body. Can be pulled out to.

Hereinafter, the first embodiment of the present invention will be described with reference to FIGS. 1 to 9.

[Basic configuration]
As shown in FIGS. 1 to 3, the roll paper holder 10 of the first embodiment is a lidless type having an open upper surface, and is a holder that rotatably holds the roll paper body 100 inside. It has a main body 12. The holder main body 12 is attached to the wall body W (see FIG. 6 and the like) via the back surface portion 12A of the main body.
Further, the roll paper holder 10 is provided with a roll paper pressing device 14 that presses the roll paper main body 100 in the holder main body 12 while allowing its rotation.

As shown in FIGS. 1 and 6, the holder main body 12 extends from the lower end portion of the main body back portion 12A and the lower end portion of the main body back portion 12A toward the tip portion, that is, the roll paper drawer side, and the main body. It has a shape having an acute-angled shape with respect to the back surface portion 12A, for example, an inclined bottom surface portion 12B formed by bending at an angle of 70 °.

The holder body 12 is made of a thin plate member, specifically a thin plate made of stainless steel, for example, 1.5 mm. Therefore, since it can be easily bent and formed by bender processing, press processing, etc., it is excellent in workability, corrosion resistance, heat resistance, etc., and an excellent effect in terms of hygiene can be obtained.
The plate thickness of the holder body 12 is not limited to 1.5 mm, but if it is too thin, the strength will be weakened, so that it is preferably about 1.5 mm to 2.0 mm. Further, the material used does not necessarily have to be made of stainless steel. A synthetic resin such as PP (polypropylene) may be used as long as it has properties such as strength, corrosion resistance, processability, and heat resistance equivalent to those of stainless steel.

As shown in FIG. 1, the back surface portion 12A of the main body is formed in a rectangular shape in a plane, and at the four corners of the front surface thereof, the back surface portion 12A of the main body, in other words, for the mounting screw 50 for attaching the holder main body 12 to the wall body W. A mounting hole 12Aa is formed.

Further, a support arm for inserting and holding a base end portion of a pressing mechanism support arm 18 composed of a linear member, which will be described in detail later, at both ends in the width direction of the main body back surface portion 12A and at the upper end portion. A holding portion 12F is provided.
The support arm holding portion 12F is formed by bending a protruding part of the back surface portion 12A of the main body forward from the surface at a substantially right angle, and has a substantially semicircular shape. The support arm holding portion 12F is provided with a holding hole (not shown) formed in the horizontal direction for inserting and holding the base end portion of the pressing mechanism support arm 18.
Here, as the linear member, for example, a stainless steel wire having an outer diameter of 20 mm is used. However, the linear member is not limited to the stainless steel wire.

As described above, and as shown in FIG. 6, the inclined bottom surface portion 12B is formed by bending the back surface portion 12A of the main body at an acute angle from the lower end at an angle of α °, for example, 70 °. The bent portion F is inclined upward, that is, toward the roll paper drawer guide portion 12C side (roll paper drawer side).
However, the inclination angle α ° of the inclined bottom surface portion 12B is not limited to 70 °. It may extend to the front side with respect to the back surface portion 12A of the main body, and may be, for example, within 90 °. However, when the angle is 90 ° or close to 90 °, the roll paper body 100 easily moves with the pulling out of the roll paper 101, so the inclination angle α ° is preferably around 70 °.

As shown in FIG. 6, the length of the inclined bottom surface portion 12B, that is, the length from the main body back surface portion 12A to the roll paper drawer guide portion 12C is when not used between the main body back surface portion 12A and the inclined bottom surface portion 12B. When the roll paper main body 100 is housed, it is set to at least the same dimension as the outer diameter dimension Φ (for example, 110 mm type) of the roll paper main body 100. Then, in this embodiment, it is set to, for example, 110 mm.
However, the length of the inclined bottom surface portion 12B is not limited to 110 mm. The roll paper main body 100 may be within a range that does not protrude forward from the roll paper drawer guide portion 12C of the inclined bottom surface portion 12B, and if there is too much difference between the outer circumference of the roll paper main body 100 and the roll paper guide portion 12C. Since the length of the inclined bottom surface portion 12B becomes long and miniaturization cannot be achieved, it is preferable that the length is set in the range of 110 mm to 120 mm, for example.

Further, as shown in FIG. 1, at the end portion of the inclined bottom surface portion 12B on the lower end side of the main body back surface portion 12A, a plurality of dust discharge lengths for discharging dust and dirt accumulated on the surface of the inclined bottom surface portion 12B The hole 12Ba is formed.
Further, rising portions 12G for strengthening are provided at both ends in the width direction of the inclined bottom surface portion 12B.

Since the back surface portion 12A of the main body and the inclined bottom surface portion 12B are formed in the above-mentioned shape, the position of the center of gravity of the roll paper main body 100 is folded when the roll paper main body 100 is accommodated and held between the two 12A and 12B. It will be located on the bent portion F side.
As a result, when the roll paper 101 is pulled out, the roll paper main body 100 is not pulled out along with the pulling-out operation, and the pulling-out operation can be smoothly performed.

[Explanation of roll paper drawer guide and roll paper cutting mechanism]
As shown in FIGS. 1 and 3, the drawer-side tip of the roll paper 101 in the holder body 12, that is, the tip of the inclined bottom surface 12B serves as a guide for pulling out the roll paper 101 as described above. A roll paper drawer guide portion 12C is formed.
The roll paper drawer guide portion 12C is formed at the tip end portion of the inclined bottom surface portion 12B, and this tip portion is directed downward from the tip end portion of the inclined bottom surface portion 12B at a predetermined angle with respect to the inclined bottom surface portion 12B. It is formed by bending at an angle of α °, for example, 70 °. The tip portion thereof has an R shape, whereby the loin paper 101 can be smoothly pulled out.

A connecting portion 12D extending downward by a predetermined dimension from the bent portion is formed on the lower side of the roll paper drawer guide portion 12C, and further, the inclined bottom surface portion 12B is formed on the tip end side of the connecting portion 12D. A cutting mechanism mounting portion 12E formed by bending substantially in parallel is formed. Then, the roll paper cutting mechanism 13 is attached to the cutting mechanism attaching portion 12E.
The connecting portion 12D and the cutting mechanism mounting portion 12E are bent and formed at a predetermined angle α °, for example, 70 °. That is, the cutting mechanism mounting portion 12E is arranged upward when the holder body 12 is mounted and fixed to the wall body W.

As shown in FIG. 1, substantially elliptical notches 12Da cut in opposite directions are formed on both sides of the connecting portion 12D in the width direction. When the roll paper 101 is pulled out, the cut portion 12Da allows a finger to be inserted into the gap portion S described below from the rear portion of the connecting portion 12D.
Further, on the front surface of the connecting portion 12D, in order to improve the appearance when the roll paper main body 100 is not housed in the holder main body 12, and to reduce the overall weight of the holder main body 12 as much as possible, in the lateral direction. A plurality of long holes 12Db are formed in the paper.

Here, as shown in FIG. 3, the vertical distance H between the R-shaped tip top of the roll paper drawer guide portion 12C and the cutting blade portion 13Ba of the roll paper cutting member 13B is set to, for example, 35 mm. .. Further, the distance L in the front-rear direction between the top of the tip of the roll paper drawer guide portion 12C and the tip of the cutting blade portion 13Ba is set to, for example, 20 mm.
However, the dimensions of the interval H and the distance L are not limited to the respective dimensions. As will be described next, a gap S is formed between the roll paper drawer guide portion 12C and the cutting blade portion 13Ba so that, for example, an index finger can be inserted to pull out the tip portion 101A of the roll paper 101. Any size may be sufficient.

As described above, the length of the inclined bottom surface portion 12B is set to, for example, 110 mm, and the distance L in the front-rear direction between the roll paper guide portion 12C and the cutting blade portion 13Ba of the roll paper cutting member 13B is set to, for example, 20 mm. Therefore, the length from the back surface portion 12A of the main body to the tip of the cutting blade portion 13Ba is set to 130 mm.

Therefore, as shown in Figures 5-8, the roll paper 101 pulled out from the roll paper body 100 accommodated in the holder body 12, the roll paper drawer guide portion 12C via the roll paper drawer guide portion 12C It is pulled out diagonally to the lower front side, and then is cut by the cutting blade portion 13Ba of the roll paper cutting member 13B.
The roll paper cutting member 13B protrudes forward by the dimension L mm (20 mm) with respect to the roll paper drawer guide portion 12C, and the distance from the R-shaped tip top of the roll paper drawer guide portion 12C to the roll paper cutting member 13B. Is set to the predetermined dimension H (35 mm), so that between the roll paper drawer guide portion 12C and the roll paper cutting member 13B, as shown in FIG. 5 and the like, a substantially triangular shape having a predetermined width in a side view is formed. The gap S is formed.

Then, when pulling out the roll paper 101, for example, the index finger is inserted into the gap S from the notch 2Da, and the tip of the roll paper 101 is sandwiched between the thumb and the gap portion S so that the roll paper 101 can be pulled out. It is a large area. That is, the roll paper 101 can be pulled out without touching the holder body 12 or the like, and the roll paper holder 10 having excellent hygiene can be obtained.

The roll paper cutting mechanism 13 has a configuration as shown in FIGS. 3 and 4.
That is, the roll paper cutting mechanism 13 is composed of a cutting blade mounting member 13A having a U-shaped cross section with a narrowed tip on the opening side, and the roll paper cutting member 13B sandwiched between the cutting blade mounting members 13A.
The lower surface of the cutting blade mounting member 13A is attached to the upper surface of the flat portion of the cutting mechanism mounting portion 12E by adhesion or the like.

As shown in FIG. 4, the cutting blade mounting member 13A is formed to have a length dimension over substantially the entire width of the inclined bottom surface portion 12B.
Further, the roll paper cutting member 13B is provided over the entire length of the cutting blade mounting member 13A. Both sides of the roll paper cutting member 13B in the thickness direction are sandwiched between the cutting blade mounting members 13A, and both sides are fixed by adhesion.

The roll paper cutting member 13B is made of, for example, hard rubber, and as shown in FIG. 4, a sawtooth-shaped cutting blade portion 13Ba is formed at the tip thereof, and the planar shape of the portion of the cutting blade portion 13Ba is formed. It is formed in a curved shape having a radius R of a predetermined dimension.
Further, as shown in FIG. 3, the roll paper cutting member 13B is mounted in a state of protruding from the tip of the cutting blade mounting member 13A by a predetermined dimension.

[Explanation of roll paper retainer]
As shown in FIG. 1, and as described above, the roll paper pressing device 14 is provided on the back surface portion 12A of the main body, and rotates the roll paper main body 100 when the roll paper 101 is pulled out from the holder main body 12. Even when the roll paper main body 100 is pressed while being allowed and the roll paper 101 is pulled out from the roll paper main body 100 in which the roll paper 101 is reduced, the roll paper pressing device 14 and the roll paper main body 100 are easily pulled out without being pressed by hand. It also has a function of preventing the roll paper body 100 from popping out of the holder body 12.

The roll paper pressing device 14 supports a roll paper pressing mechanism 15 that abuts on the outer peripheral surface of the roll paper main body 100 and presses (presses) the rotation of the roll paper main body 100 tolerably, and the roll paper pressing mechanism 15. It is configured to include a pressing mechanism support arm 18.

First, the pressing mechanism support arm 18 will be described.
The pressing mechanism support arm 18 is rotatably mounted on the back surface portion 12A of the main body with the support arm holding portions 12F at the upper left and right ends of the back surface portion 12A of the main body as fulcrums in the vertical direction with the inclined bottom surface portion 12B. It is installed.

The pressing mechanism support arm 18 is made of, for example, a stainless steel linear member having a diameter of 3 mm, and the entire planar shape is formed in a substantially U shape as shown in FIG.
The side surface shape of the pressing mechanism support arm 18 consists of two parallel first arm portions 18A extending from the base end portion on the open side in a substantially U shape toward the roll paper drawer guide portion 12C side, and the first arm portion 18A. It is formed by a second arm portion 18B that is continuous with each other and is parallel to the flat surface portion of the main body back surface portion 12A and the inclined bottom surface portion 12B.
Then, the roll paper pressing mechanism 15 is attached to the second arm portion 18B.

Insertion portions 18Aa having predetermined dimensions formed by bending outward from each other are provided at both base ends of the first arm portion 18A, and these insertion portions 18Aa are inserted into the mounting holes of the support arm holding portion 12F, and then By fixing the fixing pin 19 to the tip of the insertion portion 18Aa, the pressing mechanism support arm 18 and the roll paper pressing device 14 can be rotatably attached to the back surface portion 12A of the main body.

As shown in FIGS. 2 and 6, the roll paper pressing mechanism 15 has a pressing member 16 that abuts and presses on the outer peripheral surface of the roll paper main body 100, and a pressing member holding body 17 that holds the pressing member 16. It is configured to prepare.

The pressing member holding body 17 is made of, for example, a synthetic resin such as plastic, and is formed in a substantially U-shaped cross section with a narrow opening side.
Further, the pressing member 16 is formed by an abutting portion 16A that abuts on the outer peripheral surface of the roll paper main body 100 and a protruding piece portion 16B that is bent outward at a substantially right angle to the abutting portion 16A and has a substantially cross section. It is formed in an L shape.
The pressing member 16 is also made of a synthetic resin such as plastic, which is similar to the pressing member holding body 17, and the contact portion 16A is sandwiched between the U-shaped portions of the pressing member holding body 17 and is adhered or the like. It is designed to be installed.

As shown in FIG. 1, a plate P1 on which a product name or the like is written is attached to the surface (roll paper drawer side) of the contact portion 16A of the pressing member 16 having a substantially L-shaped cross section by adhesive or the like. .. Further, on the surface (roll paper drawer side) of the protruding piece portion 16B of the pressing member 16, as shown in FIG. 2, a plate P2 on which a catchphrase for appealing usability, good design, etc. is written is written. It is pasted by adhesion etc.
As a result, the product can be widely appealed.

Since the roll paper pressing mechanism 15 having such a configuration presses the outer peripheral surface of the roll paper main body 100, a certain weight is required. In the present embodiment, the total weight of the pressing member 16 and the pressing member holding body 17 is required. However, for example, it is set to about 80 g.
However, the weight is not limited to 80 g. If the weight is too light, it cannot play the role of a presser foot, and if it is too heavy, it cannot rotate smoothly, and as a result, the roll paper 101 cannot be pulled out smoothly. The weight of the roll paper pressing mechanism 15 is preferably 80 to 100 g.

In the roll paper pressing mechanism 15, the contact portion 16A of the pressing member 16 and one surface side of the pressing member holding body 17 come into contact with each other over substantially the entire width direction of the roll paper main body 100, as shown in FIGS. It has become like.
Then, the directions of the contact portion 16A and the protruding piece portion 16B of the pressing member 16 also change with respect to the roll paper main body 100 whose outer diameter changes depending on the usage state.

The state will be described with reference to FIGS. 6 to 8.
First, as shown in FIG. 6, when the outer diameter of the roll paper main body 100 is large in an unused state housed in the holder main body 12 or shortly after the start of use, the first arm portion of the pressing mechanism support arm 18 At 18A, both side surfaces of the roll paper main body 100 housed in the holder main body 12 are sandwiched, and the pressing member 16 of the roll paper pressing mechanism 15 is brought into contact with the outer peripheral surface of the roll paper main body 100.
At this time, the distance L2 between the surface of the main body back surface 12A and the mounting portion of the pressing member holding body 17 is larger than the distance L1 between the surface of the main body back surface 12A and the core of the roll paper main body 100. ..

Therefore, since the roll paper pressing mechanism 15 presses the roll paper main body 100 at a position separated from the core of the roll paper main body 100, the roll paper pressing mechanism 15 presses the main body as the roll paper main body 100 rotates. It does not rotate to the back surface 12A side.
Further, when the roll paper main body 100 is housed in the holder main body 12 when not in use, the position of the roll paper pressing mechanism 15 on the outer peripheral surface of the roll paper main body 100 is the pressing mechanism holding portion 12 on the upper portion of the main body back portion 12A. The length of the pressing mechanism support arm 18 and the like is set so as to be accommodated above the position of.
As a result, the height dimension of the back surface portion 12A of the main body may be small, and the back surface portion 12A of the main body and the holder main body 12 can be miniaturized.

When the roll paper 101 is pulled out in such a state, since the pressing member 16 presses the outer peripheral surface of the roll paper main body 100, the roll paper 101 is not pulled out more than necessary, and the roll The roll paper body 100 is not pulled out as the paper 101 is pulled out.
Further, the roll paper body 100 can be easily pulled out without being pressed by hand.

Next, as shown in FIG. 7, when the roll paper 101 is sequentially drawn out and used and the outer diameter of the roll paper main body 100 is smaller than that at the beginning of use, the pressing member 16 of the roll paper pressing mechanism 15 is used. Is in contact with the roll paper body 100 while pressing the outer peripheral surface of the roll paper body 100.
Even in such a state, when the roll paper 101 is pulled out, the pressing member 16 presses the outer peripheral surface of the roll paper main body 100, so that the roll paper 101 is not pulled out more than necessary, and the roll The roll paper body 100 is not pulled out as the paper 101 is pulled out.
Further, the roll paper body 100 can be easily pulled out without being pressed by hand.

Next, as shown in FIG. 8, when the roll paper 101 is further pulled out from the state of FIG. 7 and used, and the roll paper body 100 is in a state where a small amount of the roll paper 101 remains on the outer periphery of the core. In a state where one end of the pressing member 16 presses the outer peripheral surface of the roll paper body 100, the bent portion of the pressing member 16 and the protruding piece portion 16B is in contact with the inclined bottom surface portion 12B.
Even in such a state, when the roll paper 101 is pulled out, one end of the pressing member 16 presses the outer peripheral surface of the roll paper main body 100, so that the roll paper 101 is not pulled out more than necessary. The roll paper body 100 is not pulled out as the roll paper 101 is pulled out.
Further, even if the roll paper 101 is low, the roll paper body 100 can be easily pulled out without being pressed by hand.

FIG. 9 shows a state in which the roll paper main body 100 is not housed in the holder main body 12.
At this time, the pressing mechanism support arm 18 is in a state where the first arm portion 18A is in contact with the surface of the back surface portion 12 of the main body, and the pressing member 16 of the roll paper pressing mechanism 15 and the protruding piece portion 16B are in contact with each other. The bent portion is in contact with the inclined bottom surface portion 12B.

Next, based on FIG. 10, the principle of the mechanism by which the roll paper main body 100 does not pop out from the holder main body 12 as the roll paper 101 is pulled out will be described.
As shown in FIG. 10, the center of gravity point C of the toilet paper (roll paper body 100) attached to the holder body 12 is separated from the upper surface of the inclined plate (tilted bottom surface portion 12B), and the holder body of the roll paper body 100 There are two contact points in the 12: the surface of the vertical fixing plate (main body back surface 12A) and the surface of the inclined bottom surface 12B, and the curved roll paper main body 100 is constantly maintained with falling acceleration and has potential. Since the energy becomes unstable and the weight of the roll paper body 100 is also dispersed, the roll paper 101 can be easily pulled out.

Here, the weight Wgr of the roll paper main body 100 is supported by a force F2 acting perpendicularly to the back surface portion 12A of the main body and a force F1 acting perpendicularly to the inclined bottom surface portion 12B. And the size is when the angle between the back surface portion 12A of the main body and the inclined bottom surface portion 12B is 70 °.
F1 = Wgr cos 20.0 ° = 0.94 Wgr
F2 = Wgr tan 20.0 ° = 0.36 Wgr
Given in.
In FIG. 10, the roll paper body 100 is a product having a diameter of 110 mm.

Next, how to use the roll paper holder 10 having the above configuration will be described.
Prior to use, the user first accommodates (sets) the roll paper body 100 in the holder body 12, and at this time, sets the roll paper 101 in a state of being pulled out from the lower side of the roll paper body 100.
Here, since the holder main body 12 does not have a lid, the roll paper main body 100 can be easily manually operated from above the holder main body 12 by rotating the roll paper pressing device 14 to the upper side of the main body back portion 12A. Can be accommodated.

Further, after accommodating the roll paper main body 100, the tip portion 101A of the roll paper 101 pulled out from the roll paper main body 100 is pulled out from the bottom side of the roll paper main body 100 diagonally forward and upward along the upper surface of the inclined bottom surface portion 12B. Further, the roll paper is pulled out to the roll paper cutting mechanism 13 side, that is, diagonally forward and downward side via the upper surface portion of the roll paper drawer guide portion 12C for pulling out the roll paper .

At this time, the roll paper 101 to be pulled out is guided from the upper surface of the inclined bottom surface portion 12B to the R-shaped portion of the upper end surface of the roll paper drawer guide portion 12C, so that the roll paper 101 is moved back and forth when the roll paper 101 is pulled out. It is possible to pull out in a stable behavior state that does not shake.

When an unused roll paper main body 100 is housed in the holder main body 12, the back side (rear side outer peripheral portion) of the roll paper main body 100 is on the surface of the main body back portion 12A as shown in FIGS. While abutting, the bottom surface side (bottom surface side outer peripheral portion) of the roll paper body 100 is held by the front side portion of the inclined bottom surface portion 12B.

Further, as described above, when the user grabs the tip of the roll paper 101 that is pulled out forward with the roll paper cutting mechanism 13 and pulls it out, it tilts with the back surface portion 12A of the roll paper main body 100 that is rotated by the pulling out. A frictional force due to the weight of the roll paper body 100 is generated between the bottom surface portion 12B and the front side portion.
For this reason, each frictional force generated suppresses the acceleration of the roll paper body 100 from moving out, prevents the roll paper body 100 from jumping forward, and realizes a smooth and stable paper feed rate. For example, only one hand is used. However, the tip portion 101A of the roll paper 101 can be easily pulled out.

In addition to the above frictional forces, the pressing mechanism 15 of the roll paper pressing device 14 is in contact with the outer peripheral surface of the roll paper main body 100, and the pressing mechanism 15 always presses the roll paper main body 100 with a predetermined load. Since the paper is pressed, the roll-out acceleration of the roll paper body 100 is also suppressed, the roll paper body 100 is prevented from jumping forward, and a smooth and stable paper feed rate is realized, for example. The tip 101A of the roll paper 101 can be easily pulled out with only one hand.

When cutting the tip portion 101A of the pulled-out roll paper 101, first, the tip portion 101A of the roll paper 101 extending via the upper end surface portion of the roll paper guide portion 12C is cut at one corner of the cutting blade portion 13Ba. It may be pressed against the paper to break through the portion, and then the tip portion 101A of the roll paper 101 may be cut by pushing it diagonally backward and downward, or by pulling it diagonally backward and downward.

With respect to the tip portion 101A of the cut roll paper 101, the tip portion 101A of the roll paper 101 to be pulled out next is a roll that is pulled out to the portion of the cutting blade portion 13Ba as shown in FIG. 5 (B). The tip portion 101Aa of the paper 101 hangs down from the upper end surface portion of the roll paper guide portion 12C into the gap portion S.
Then, when the tip portion 101Aa of the new roll paper 101 is pulled out next, the user inserts, for example, the index finger from the notch portion 12Da into the gap portion S, and the front and back surfaces of the tip portion 101Aa of the roll paper 101 hanging down. Can be easily pulled out to the roll cutting member 16 side by sandwiching it between the index finger and the thumb.

(Effect of the first embodiment)
According to the first embodiment having the above configuration, the following effects can be obtained.
(1) When the roll paper 101 is pulled out from the roll paper main body 100 housed in the holder main body 12, the roll paper pressing device 14 allows the roll paper main body 100 to rotate and covers the outer periphery of the roll paper main body 100. Since it is pressed, the roll paper 101 of the roll paper body 100 housed in the holder body 12 is pulled out, and even if the roll paper 101 remains low in the roll paper body 100, the roll paper body 100 is not pressed. The 101 can be easily pulled out.

(2) The roll paper pressing device 14 is configured to include a roll paper pressing mechanism 15 and a pressing mechanism support arm 18, and the pressing mechanism support arm 18 is rotatably provided on the back surface portion 12A of the main body. When the roll paper body 100 is housed in the holder body 12, the roll paper body 100 is easily moved to the holder body 12 by rotating the roll paper pressing mechanism 15 upward of the holder body 12 by the pressing mechanism support arm 18. It can be accommodated, and this has the effect that the labor of accommodating the roll paper main body 100 can be reduced.

(3) Since the distance L2 between the surface of the main body back surface 12A and the mounting portion of the pressing member holding body 17 is larger than the distance L1 between the main body back surface 12A and the core of the roll paper main body 100, the roll paper pressing mechanism 15 is used. The roll paper body 100 is pressed at a position distant from the core of the roll paper body 100. Therefore, the roll paper pressing mechanism 15 does not rotate toward the back surface portion 12A of the main body as the roll paper main body 100 rotates.

(4) When the roll paper main body 100 is housed in the holder main body 12 when not in use, the position of the roll paper pressing mechanism 15 on the outer peripheral surface of the roll paper main body 100 is the pressing mechanism holding portion on the back surface portion 12A of the main body. Since it is housed above the position of 12, the height dimension of the back surface portion 12A of the main body may be small, and as a result, the back surface portion 12A of the main body, and thus the holder main body 12, can be miniaturized.

(5) The length of the inclined bottom surface portion 12B from the main body back surface portion 12A to the roll paper drawer guide portion 12C is between the main body back surface portion 12A and the inclined bottom surface portion 12B when the roll paper main body 100 (110Φ) is not used. When the type) is accommodated, the length of the inclined bottom surface portion 12B can be shortened because the outer diameter dimension of the roll paper main body 100 is set to substantially the same dimension.
As a result, when the holder body 12 is housed in the wall-to-W, it does not protrude significantly toward the user side, so that it does not interfere with the use and can be used safely. It can also be used in a toilet room where only a small space can be taken.

(6) The shape of the holder main body 12 is bent from the lower end of the main body back portion 12A attached to the wall body W and the lower end of the main body back portion 12A at an angle of 70 ° with respect to the main body back portion 12A and extends forward. Since the shape has the inclined bottom surface portion 12B provided, when the roll paper main body 100 is housed in the holder main body 12, the center of gravity of the roll paper main body 100 is located on the bent portion side. As a result, when the roll paper 101 is pulled out, the roll paper main body 100 is not pulled out with the drawer of the roll paper 101 in combination with the holding function of the roll paper holding device 14, and an extra amount is increased. The roll paper 101 can be easily pulled out without being pulled out.

(7) The back surface portion 12A and the inclined bottom surface portion 12B of the main body, the connecting portion 12D and the cutting mechanism mounting portion 12E following the inclined bottom surface portion 12B are formed of a thin plate made of stainless steel, for example, about 2.0 mm. Processing can be easily performed by bender processing, press processing, or the like. As a result, the workability is excellent, the corrosion resistance, the heat resistance, and the like are excellent, and further, an excellent effect in terms of hygiene can be obtained.

(8) Since a gap portion S having a substantially triangular side surface is formed between the roll paper pull-out guide portion 12C and the roll paper cutting member 13B, for example, when pulling out the roll paper 101, the index finger is used. The roll paper 101 can be pulled out by inserting it into the gap S and sandwiching the tip of the roll paper 101 with the thumb. That is, the roll paper 101 can be pulled out without touching anywhere such as the holder body 12. As a result, even when the roll paper holder 10 is housed in a medical facility such as a hospital, for example, even when an inpatient who has some bacteria uses the toilet, there is no possibility that some bacteria will adhere to each part of them. As a roll paper holder 10 having excellent hygiene, it can be provided to medical facilities and the like.
