[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll paper holder for holding a rolled paper sheet, such as a toilet paper or other roll paper, an aluminum wheel, a plastic film, or a non-woven fabric, which is similar to a roll paper, and particularly to a roll paper cover. The present invention relates to a roll paper holder that allows a roll paper picking margin to be formed from a lower part of a blade edge by a simple operation.

[0002]

2. Description of the Related Art Conventionally, as a roll paper holder for toilet paper or the like, a roll paper holder is known in which a tip of the roll-shaped paper is pulled out from a cutter by a predetermined size so that a person can easily take it out. For example, a cutter for pressing Rhone-shaped paper and cutting it with its end as a reference is provided with a window slightly rearward from the tip of the blade, and if roll paper is pulled out from this window and cut, it will be used next from the window. There is one in which the end portion of the roll paper is projected so that a person can easily pick it up.

Further, as described in Japanese Utility Model Application Laid-Open No. 60-105497, a rack which moves up and down in accordance with the vertical rotation of a cutter and a pinion attached to a support shaft of roll-shaped paper are provided. It is well known that the pinion is engaged with the roll-shaped paper so as to rotate only in the pulling-out direction of the roll-shaped paper so that the roll-shaped paper is pulled out according to the raising and lowering of the cutter.

However, in the former case of the above-mentioned conventional example, the end portion of the roll paper pulled out is exposed, and the work of pulling out and cutting is performed in the upward portion of the cutter, which is dangerous and unhygienic. In addition, it is necessary to pass the tip of the roll-shaped paper through a window provided in the cutter each time the roll-shaped paper is set, which is very troublesome. Also in the latter case, the cutter needs to be lifted up and down by hand, and the tip of the roll-shaped paper cannot be automatically projected from the cutter before the next use.

As a toilet paper holder intended to solve these problems, for example, Japanese Utility Model No. 6-36
A rack and ratchet type pinion, as described in Japanese Patent Publication No. 798, for enabling roll paper to move up and down together with a support shaft, and rotating the support shaft in a direction of pulling out the roll paper by a predetermined angle in accordance with the vertical movement. Is provided, the roll-shaped paper is lowered on the spindle, the roll-shaped paper is cut with a cutter, and then the cutter is returned to its original position. It is also known that the tip of the roll-shaped paper automatically rotates so as to project from the tip of the cutter.

[0006]

However, in this conventional example, since the roll paper cylinder core support shaft is rotated up and down to rotate the rack paper through the rack and the ratchet type pinion, the roll paper cylinder core is used. It is necessary to have a structure in which the rack is removably attached to the support shaft so that it does not rotate idly, and a structure in which a rack and a ratchet type pinion are combined, and each of these structures is complicated and troublesome to assemble and workability is high. bad. Further, in this conventional example, since the cylinder core of the roll paper is supported by the long support shaft, the left and right sides of the plane-shaped substantially U-shaped holder body having at least the left and right side portions and the back wall mounting portion are provided. An essential problem that it cannot be used in the toilet paper holder where the roll paper can be easily attached / detached due to the paper holding member that is installed symmetrically on the inner surface of the part and comes in and out when the roll paper is taken in and out, and engages with the paper core. There is a point.

In addition to this, Japanese Patent Laid-Open No. 10-201
The one described in Japanese Patent No. 661 is also well known. This conventional example
In a paper holder provided with a support body having a substantially U-shaped side wall opened on the front side and a support shaft rotatably holding a roll paper pivotally supported between the left and right side walls of the support body, the support is provided. A cover is pivotally supported between the left and right side walls of the body so that it can swing up and down, and an arc-shaped rack centering on its mounting axis is hung vertically on the lower surface side, and this cover is urged to return when pushed down. A second spring that presses and urges the first spring and the paper roll surface, and is pivotally supported on the cover concentrically with the mounting shaft of the cover so as to be swingable within a specific range. The H-shaped arm that receives and transmits the bias of the spring is associated with the one-way clutch that is pivotally supported on the swing end side of the arm and that engages with the rack of the cover and transmits the rotation only in one direction. Press the roll paper An automatic discharge type paper holder; and a roller rotating.

According to this conventional example, the roll paper mounted on the paper holder is automatically rotated by the rotational force of the roller when a specific portion of the cover is pressed and returned to be pushed down, and the leading end of the paper is fixed. Although it is possible to eject only the length corresponding to the pressing amount of the cover, to actually use the roll paper, first pull out the roll paper for the desired length, then fix the tip side of the cover with one hand, Or
While pressing against the outer peripheral surface of the roll paper against the rising elasticity,
With the other hand, you have to lift the above-mentioned paper and apply the base to the tip of the cover to cut the paper, so you cannot cut the paper with one hand, and this paper cutting operation is troublesome and troublesome. There is an essential and major problem in use.

Further, also in this conventional example, as in the above-mentioned conventional example, since the cylinder core of the roll paper is supported by the long support shaft, it is almost a plane including at least the left and right side portions and the inner wall surface mounting portion. Toilet paper that can be easily attached and detached by a paper holding member that is installed symmetrically on the inner surface of the left and right sides of the U-shaped holder main body There is an essential problem that it cannot be used as a holder.

The present invention has been made to eliminate many problems in each of these conventional examples. The purpose of the present invention is to load roll paper into a roll paper holder and remove used cylinder cores. In addition to facilitating the operation, you can automatically roll out the leading edge of the roll paper from the lower edge of the blade on the front edge of the cover toward you, by simply lifting the roll paper slightly without touching the holder or cover. There is to be.

The roll paper 4 can be inserted into the cylinder core 4A as shown in FIGS. 1 and 2 so that the roll paper 4 can be rotated with respect to the holder 1 about the cylinder core.

After that, when the user manually tilts the upright cover 5 from the state shown in FIG. 2 to the state shown in FIG. 4 (opening of about 45 °) against the projection output of the piston 10, the cover 5 is in turn turned off. As shown in FIG. 5, the protrusion force of the piston 10 causes the roll paper 4 to face down toward the upper surface of the roll paper 4, and the roll paper sliding elastic pressure portion on the lower surface of the cover makes elastic contact with the upper portion of the roll paper 4, and the roll paper elastic pressure initial setting state of the cover 5 is set. At the time of the above setting, the user preliminarily pulls out the roll paper 4 in FIG. 2 by a desired length to make a roll paper drawer / plucking allowance 4a, and pulls the roll paper drawer / plucking allowance 4a to obtain a desired size. The base portion of the lever 5a
On the other hand, as shown in FIG. 5, the roll paper 4 can be cut and used by the blade edge 5a by forcibly bending upward and strongly moving upward.

At the time of next use, as shown in FIG. 7, it is necessary to extend the cut edge 4b of the cut roll paper 4 out of the cover immediately below the cutting edge 5a to make a picking margin. Roll paper 4 before feeding roll paper shown in FIG. 7
Against its own weight and the elastic force of the roll paper of the cover 5 by the piston spring 9, and when the roll paper 4 is lifted up from the state of FIG. 7 by the radius height of the cylinder core 4A as shown in FIG. 8, the protrusion in FIG. The first contact point P1 of the roll paper 4 that is in contact with the one-pointed tip 11B slides upward as it is and moves to a point P1 which is a dimension L higher than the protruding one-pointed tip 11B as shown in FIG. Although the second contact point P2 is generated, the cut edge 4b of the roll paper 4 remains just below the blade edge 5a of the cover 5 inclined to the upper right as shown in FIG.

Next, when the above lifting force is removed from the roll paper 4, this time, when the roll paper 4 returns to the original state of FIG. 7 by the lowering force of the sum of its own weight and the elastic force of the cover 5, The second descending roll paper contact point P2 is generated by the obliquely downward force of the roll paper 4 directed toward the tip 11B of the protruding piece by the cover 5.
The outer peripheral portion of the roll paper can be apparently kicked up by the tip 11B of the protruding piece, and the roll paper 4 is rotated by the above dimension L in the feeding direction, so that the roll paper pull-out allowance of the dimension L as shown in FIG. 4a can be produced, and at this time, the elastic contact portion between the protruding piece tip 11B and the roll paper 4 is almost the same as the position of the second contact portion P2.

Thereafter, the roll paper drawer picking allowance 4a
Can be pulled out by a desired length against the elastic contact friction between the cover 5 and the projecting piece 11 with respect to the outer peripheral surface of the roll paper, and the base part thereof can be cut with the cutting edge 5a as shown in FIG. At the time of the next use, the picking margin 4a can be made outside the blade edge 5a as shown in FIG. 9 by the roll paper feeding procedure similar to the previous use shown in FIG. 7 and FIG. Even when the roll paper 4 has a small diameter, a grip allowance 4a having a dimension L is made as shown in FIG. 12 corresponding to FIG. 9 through the state of FIG. 11 corresponding to FIG. Can be used. In addition, in each of the drawings from FIG. 10 to FIG.
The same or equivalent portions in each of FIGS. 7 to 9 are shown.

After the cover 5 is opened manually, the used cylinder core 4A is tilted upward by moving the cylinder core 4A upwards against the horizontal restoring force. As described above, the roll paper 4 can be detached, and the new roll paper 4 is pivotally set on the holder 1 and the upper portion of the roll paper 4 is elastically pressed by the cover 5, whereby the following usage pattern can be adopted.

As shown in FIGS. 6 and 12, the roll paper 4 or the cylinder core 4A of the roll paper 4 is placed in the cylinder core receiver 3 with the cover 5 lying down.

[0027]

The roll paper elastic means of the cover 5 uses not only the projection output of the piston 10 by the pulling spring 9 in the illustrated example but also the projection output of the piston 10 by the push-up spring inside the cylinder, or other well-known rolls. Cover repressing means for the paper 4 can be adopted. Also, roll paper 4
As means for elastically contacting the protruding piece 11 with the upper part of the rear surface, an elastic body such as a coil spring or a rubber cord can be used in addition to the coil spring 12 of the illustrated example, and the tip 11B of the protruding piece 11 can be rolled. Instead of elastically contacting the upper portion of the rear surface of the paper 4, a friction member such as a rubber piece is provided on the inner surface of the upper portion of the projecting piece 11, or the projecting piece 11 as shown by the chain line in FIGS.
The upward slanting piece 11D is integrally projected on the inner surface of the upper part of the
Alternatively, the inner surface of the upper portion of the protrusion 11 may be elastically contacted with the upper portion of the rear surface of the roll paper 4 to rotate the roll paper 4 in the payout direction by the descending return force after the roll paper 4 is raised.

The pivot portion 6 of the cover 5 is pivotally supported by engaging a hinge pin projecting from the cover 1 body with a hinge hole (recess) of the holder side piece 2 or a hinge hole (recess) of the cover 5. The cover 5 can be pivotally supported between the holder side pieces 2 and 2 even when the hinge pin is engaged with a hinge pin integrally projecting from the side piece. In addition, the cylinder 8 and the pivotally supporting portions 2a and 7a of the piston 10 are also the cylinder 8
Hinge hole (recess) and piston 10 hinge hole (recess)
With the hinge pin serving as the pivotal support portion 7a of the projecting piece 7 and the hinge pin integrally protruding from the side piece serving as the hinge portion 2a of the side piece 2, respectively, or with the hinge portions 2a, 7a.
The hinge holes (recesses) and the hinge pins can be replaced with each other to form the respective pivotal support portions 2a and 7a, and the side piece cover 2A prevents the pivotal support portions from coming off easily. The stopper is attached by a well-known means such as a flange of a flat head screw screwed on the tip of the pivot pin or a crushed flange on the tip of the pivot pin.

Further, a blind cover 2A for the side piece 2
As an example of the mounting means of the cylinder 8, the cylinder 8 is attached to the outer surface of the side piece 2.
And a plastic cover with the same side surface covering the piston 10 and a plastic cover corresponding to a side piece which is slightly larger than the side pieces 2 and 2 are screwed to the holder 1 by known male and female engagement locking means. Although it can be mounted, these side blindfold covers 2A may be omitted.

[0030]

Since the present invention employs the above-mentioned modes, it has the following effects. When the roll paper 4 before being fed out is resisted by its own weight and the roll paper elastic force of the cover 5 by the piston spring 9 and the roll paper 4 is lifted up to the radius height of the cylinder core 4A, the roll paper 4 comes into contact with the tip 11B of the protruding piece. The first contact point P1 of the rolled paper 4 slides upward as it is, and is a point P1 above the protrusion tip 11B by the dimension L.
After removing the above lifting force from the roll paper 4 after making the second contact point P2 below it,
When the roll paper 4 returns to its original state by the lowering force of the sum of its own weight and the elastic force of the cover 5, the second downward movement is mainly caused by the oblique lowering force of the roll paper 4 toward the tip 11B of the protruding piece by the cover 5. The outer peripheral portion of the roll paper contact point P2 can be apparently kicked up by the tip 11B of the protruding piece, and the roll paper 4 is rotated by the above dimension L in the feeding direction, so that the roll paper drawer knob of the dimension L can be picked up. The margin 4a can be formed outside the cover blade edge 5a.

Therefore, according to the present invention, there is an excellent effect that the feeding of the roll paper, the desired length cutting and the replenishment of the roll paper in the holder can be stably and reliably performed many times by one hand operation. According to each of the second and third aspects of the invention, the protrusion upper tip 11B or the upward sloping piece 1 is provided on the upper rear surface of the roll paper 4.
Since 1D is elastically contacted, it is possible to add an effect that the roll paper 4 can be more surely kicked up and rotated in the feeding direction when the roll paper 4 is returned to the lowered state.
