Description

[Detailed explanation of the invention] A. Purpose of the invention a. Industrial application field The present invention relates to a toilet paper holder, which can hold multiple rolls of paper for use in places where a large amount of paper is used, such as the toilets of various organizations. This invention relates to an improvement of a paper holder that stores individual pieces of paper.

b. Prior Art Most toilet paper holders for general household use can store one roll of paper, and that is sufficient. However, school
In the toilets of various organizations such as hospitals and office buildings, extra rolls of paper are needed because a large amount of paper is used, but if you leave it outside, it will get dirty, and you need to replace it every time one roll runs out. This is time-consuming and complicated to manage. Therefore, it is desirable to store spare roll paper in the holder as well.

Several types of multiple toilet paper holders of this type have already been devised, but
The present applicant had also previously proposed the method described in Japanese Utility Model Application Publication No. 153296/1983. The toilet paper holder has an oblong cylindrical shape with one part of the circumference flattened to serve as a wall mounting plate, and the other end covers a case (storage body) that can store multiple rolls of paper. The roll paper support shaft is fixed, and the other end of the case is provided with a lockable opening/closing lid that has a paper core tube outlet in the center and a bearing sleeve to prevent the support shaft from swinging, and the front of the case is equipped with a lockable opening/closing lid that has a paper core tube outlet in the center and a bearing sleeve to prevent the support shaft from swinging. An elongated hole reaching the leaning part and a paper pull-out hole are provided on the other end side, and a paper extrusion plate is loosely fitted to the support shaft,
In addition, the push-out plate is characterized in that a knob attached to the extrusion plate is made to protrude outside from the elongated hole.

According to this toilet paper holder, when the roll paper corresponding to the paper pull-out hole is used among the plurality of roll papers housed in the paper support shaft, the paper push-out plate can be slid using the knob. With this, the next roll paper moves to the pull-out hole side, and the core tube of the used roll paper is conveniently ejected from the core tube outlet by being pushed by the side surface of the roll paper.

C. Problems that the invention aims to solve However, in the toilet paper holder described above, when the paper is pulled out from the paper pull-out hole during use, as the roll paper rotates on the support shaft, the side end surface comes into contact with the roll paper. The spare roll paper next to it also rotates. This may also cause the adjacent spare roll paper to rotate together. Since the first end of the roll paper is only lightly glued, it easily peels off due to its rotation, and it also unravels and gets tangled in the holder.
It will become like a dumpling. Therefore, even if an attempt is made to slide the spare roll paper toward the pull-out hole later, it is difficult to move and there are problems such as paper loss.

The present invention is an attempt to solve the above-mentioned problems of the conventional toilet paper holder.
In other words, the purpose of the present invention is to prevent multiple roll papers on a support shaft installed horizontally in a holder from rotating together when the paper is pulled out, so that even if the adhesive at the initial end peels off, the papers will not unravel and get tangled. To provide a toilet paper holder which can be smoothly slid when necessary without sagging and eliminates paper loss.

B. Structure of the invention a. Means for solving the problems In the toilet paper holder of the invention, a support shaft 3 capable of holding a plurality of roll papers 2 is fixed in one side in a horizontally long case 1. The end of the case 1 is installed horizontally from one side plate 4 to the other side plate 5, and the paper core tube 6 has a discharge hole 7 in the other side plate 5 of the case 1, and a paper drawer opening 9 is provided near the other side plate 5 of the peripheral plate 8. Further, elongated guide holes 10 are formed in each of the circumferential plate 8 from the side plate 4 side to the drawer opening 9 side, and the grip part 12 of the sliding member 11 of the roll paper 2 protrudes from the elongated hole 10. The support shaft 3 is made thicker by the shaft part 13 for the roll paper in use and thinner by the shaft part 14 for the spare roll paper, and the boundary thereof is formed by a tapered cross-sectional part 5.
It is formed by

In the above configuration, the case 1 has an oblong shape capable of storing, for example, about three roll papers 2, and is made of metal or plastic depending on the place of use. Further, in order to enable the case 1 to be fixed to the wall surface of the toilet, one surface of the case 1, for example, the back surface, is formed into a flat shape.

The other side plate 5 in which the discharge hole 7 of the paper core tube 6 is formed
To store roll paper 2 in the holder,
For example, it can be opened and closed using a hinge 16, and can also be locked. Further, the discharge hole 7 of the plate 5 is formed to be slightly larger than the outer diameter of the paper core tube 6.

It is desirable that the paper drawer opening 9 be provided at a slightly lower portion of the front surface of the peripheral plate 8, and that the elongated guide hole 10 be also provided on the front surface of the same plate 8, but the present invention is not limited thereto. The sliding member 11 of the roll paper 2 may be, for example, in the form of a plate fitted around the support shaft 3 as shown in the figure, and connected to the grip portion 12 protruding from the elongated hole 10. However, the support shaft 3 is not limited to a plate shape.
It is not necessary to fit the grip portion 12, but any shape is sufficient as long as it can be slid by pushing the side end surface 17b of the preliminary roll paper 2b by sliding the grip portion 12. In addition, the above-mentioned drawer opening 9
The width of is slightly larger than the width of one roll paper 2, and the width of the guide slot 10 is approximately equal to the width of one roll paper 2 multiplied by the number of roll papers 2 that can be stored. Form it.

As described above, the support shaft 3 is thick at the shaft portion 13 for the roll paper in use and thin at the shaft portion 14 for the spare roll paper. That is, the shaft portion 14, which fits the roll paper 2a in use at the position corresponding to the paper drawer opening 9, is made thicker, and the spare roll paper 2b is made thicker.
The shaft portion 14, which is fitted around the shaft portion 14, is formed to be thin. For example, if the inner diameter of the core tube 6 of the roll paper 2 is 38 mm, the shaft diameter of the thick shaft portion 13 may be approximately 37 mm, and the shaft diameter of the thin shaft portion 14 may be approximately 28 mm. The boundary between both shaft portions 13 and 14 is formed into a cross-sectional tapered portion 15 having a length of, for example, about 15 mm.

Note that the support shaft 3 does not necessarily have to have a circular cross section. Also, the shaft part 13 for the roll paper in use
It is preferable to form a braking rib 18 in contact with the inner circumferential surface of the paper core tube 6. In addition, the sliding member 11 and the grip portion 12 of the spare roll paper 2b make the sliding movement light, so that the spare roll paper 2b can be easily moved by the vibration caused by the rotation of the roll paper 2a during use and by the tapered part 15. It is configured to be retractable toward the shaft portion 14 for the spare roll paper 2b.

In the figure, reference numeral 19 denotes recessed portions for positioning the knob, which are formed at the lower edge of the elongated guide hole 10 at intervals approximately equal to the width of the roll paper 2. 20 is a bearing sleeve for preventing rocking of the support shaft;
It is provided inside the core tube discharge port 7 and simultaneously positions the roll paper 2a in use.

b. Effect The present invention is used when a plurality of roll papers 2 (three in the illustrated example) are placed in the toilet paper holder attached to the wall of the toilet, and the side plate 5 is opened and the support shaft 3 is fitted. Let it go and store it.
At that time, the sliding member 11 and the knob portion 12 are
It comes to the back side of the spare roll paper 2b. To use paper, pull the roll paper 2a in use from the paper drawer opening 9 at the corresponding position.
can be pulled out from its end 21. When the user finishes using the roll paper 2a, the sliding member 11 is slid toward the paper drawer opening 9 using the grip portion 12. This moves the pressed spare roll paper 2b, pushes the next spare roll paper 2b to the position corresponding to the drawer opening 9, and makes it fit around the thick shaft part 13 with its core tube 6a, and accordingly The core tube 6a of the roll paper 2a is extruded from the core tube outlet 7, and a new roll paper becomes usable.

In the above case, when the paper end portion 21 is pulled out from the drawer opening 9, the roll paper 2a in use rotates on the support shaft 3 and the paper is fed out. At that time, the rotating roll paper 2a in use and the next spare roll paper 2
If it is assumed that the side end surfaces 17a and 17b of
The rotational force is also transmitted to b, and the preliminary roll paper 2
b will rotate together.

However, in the present invention, as mentioned above, the support shaft 3
Since the shaft part 13 for the roll paper in use is thick, the shaft part 14 for the spare roll paper is thin, and the boundary between the shaft parts 13 and 14 is formed into a tapered section 15, the spare roll paper 2b is Does not co-rotate.

That is, first of all, the next preliminary roll paper 2b
Even if it tries to touch the roll paper 2a in use, it has to climb the tapered section 15 from the thin shaft section 13 to the thick shaft section 14. Even if the spare roll paper 2b begins to climb up the tapered part 15, the spare roll paper 2b will slide down the tapered part 15 due to the shake and vibration of the support shaft 3 caused by the rotation of the roll paper 2a in use. Then, it returns to the shaft section 14 for thin spare roll paper. Therefore, the spare roll paper 2b tends to separate from the roll paper 2a in use, so
The both side end surfaces 17a and 17b are not in contact with each other, and rotation due to frictional force is not transmitted. Furthermore, even if the end surfaces 17a and 17b are in contact with each other temporarily, they tend to separate and reduce the frictional force, so the preliminary roll paper 2b
There is no frictional force sufficient to cause the two to rotate together.

Second, if the roll paper 2a in use and the spare roll paper 2b are
Even if a rotating force is transmitted due to frictional force, the shaft parts 13 and 14 that are fitted around the support shaft 3 have different thicknesses, so they do not rotate together. That is, the roll paper 2a in use and the spare roll paper 2b are separated from the rotation center line x of the former 2a by the latter 2b.
The center line y of rotation is at the lower position, and the center of gravity is also lower. If the spare roll paper 2b tries to rotate with the rotation of the roll paper 2a currently in use, an extra force will be generated to lift the lowered center of gravity compared to the case where the rotation center lines x and y coincide. , must be transmitted from the former 2a to the latter 2b.
However, the side end surfaces 17 of both roll papers 2a and 2b
Even if a and 17b are in contact, it is only natural contact, so the frictional force is small, and no force is generated to lift the center of gravity of the preliminary roll paper 2b and rotate it, so the preliminary roll paper 2b is It doesn't turn. Moreover, since the center lines x and y of rotation of both roll papers 2a and 2b do not coincide, the rotation of the spare roll paper 2b is forced to be an eccentric rotation, so to speak, and since the rotation is not smooth, it becomes even more difficult to rotate the spare roll paper 2b together. ing.

C. Effects of the Invention As is clear from the above, the toilet paper holder of the present invention differs from the conventional straight rod-shaped paper support shaft in that the shafts have different thicknesses, and the border has a tapered cross-section. It was established as a department. Thereby, the rotation of the roll paper in use is not transmitted to the spare roll paper, and co-rotation can be reliably prevented. Therefore, the spare roll paper no longer unravels inside the holder and becomes tangled and lump-like as in the past, and the spare roll paper can be moved smoothly and paper loss can be eliminated. This kind of holder has a beneficial effect.

As shown in Fig. 5, the difference in support shafts is such that the shaft portion 13 for the roll paper 2a in use is located above the shaft portion 14 for the spare roll paper 2b, even though they have the same thickness. If the paper core tube 19 is formed on the inclined peripheral surface 22, the same effect can be obtained for the roll paper 2 having a large diameter.
