Description

The present invention relates to a roll paper holder, and more particularly to a roll paper holder that rotates and feeds roll paper such as toilet paper.

When the paper (roll paper) wound around the core is appropriately pulled out and used, such as toilet paper, the previous paper cutting edge is a margin for the next user. However, the cutting edge is often hidden under the cover plate, and as the hand becomes handicapped with age, it becomes very difficult to pull out the paper. An apparatus has been proposed in which a roll paper is rotated semi-automatically after being cut out, and the paper is fed out as an allowance for the next use. Patent Documents 1 to 3 attach a spring under the cover plate, press the cover plate in the standby position to press the spring against the paper, and when the cover plate returns to the standby position, Rotate the toilet paper. Moreover, in patent document 4, a toilet paper is rotated using a rotation drive means, and a cutting edge hangs down from under a cover plate.

When a spring is used under the cover plate as disclosed in Patent Documents 1 to 3, the amount that can sag from the bottom of the cover plate depends on the amount of spring stroke. Also, if the paper is soft, the spring can bite into the paper and the amount of stroke cannot be secured, so the amount that can hang down from under the cover plate is small.
In the case of using the rotation driving means as in Patent Document 4, it is necessary to secure energy such as electric power separately.

The purpose of this device is to provide a roll paper holder that does not require energy such as electric power and allows a sufficient amount of paper to be manually dropped from a cover plate as a margin for subsequent use. .

The roll paper holder of the present invention that solves the above problems is a roll paper holder having a core member that is inserted into a central cavity of the roll paper, and a cover member that covers the upper side of the roll paper.
The cover member has, on its front side, an arm member that swings about an axis parallel to the core member;
A biasing member biasing the front side of the arm member to a standby position lifted;
A pressing member attached to the front end of the arm member and having a cutting blade;
A roller that rotates by swinging the arm member;
When the roll paper wound around the roller is loaded on the core member, the belt-shaped member hangs down by a weight attached to one end while being in surface contact with the rear side of the roll paper,
When the arm member swings when the pressing member is pressed, the roller is rotated so as to unwind the belt-like member, and when the arm member returns to the standby position by the biasing member, the belt-like shape Rotating the roller to wind up the member.

According to the present invention, the amount to be drawn out from the roll paper as the allowance can be determined by adjusting the diameter of the roller with respect to the magnitude of the swing of the arm member. Furthermore, since the belt-shaped member is in surface contact with the roll paper over a wide range, it is possible to reliably pull out the allowance, and the belt-shaped member does not crush the roll paper and leave a mark.

It is the whole perspective view and sectional view showing the composition of a roll paper holder. It is a component diagram of the principal part of a roll paper holder. It is a figure which shows operation | movement of a roll paper holder.

The roll paper holder 1 of a present Example is demonstrated. In the following description, an example will be described in which the function of dropping the allowance for next use from the cover plate is attached later to the cover member 4 that is already used as equipment.

1, the roll paper holder 1 is pivotally supported by a holder main body 2 that accommodates the roll paper P, and a shaft 19 provided on the upper side of the roll paper P and on the rear side of the holder main body 2 (the left side in the drawing). The cover member 4 and the core member 6 inserted into the central cavity of the roll paper P are provided. The cover member 4 is for covering the upper side of the roll paper P.

A base member 100 is attached to the cover member 4 with screws 101 or double-sided tape (not shown). The base member 100 is attached to the cover member 4 by retrofitting, and the arm member 3 is supported so as to be swingable around a shaft 18 located on the front side (the drawing, the right side) of the cover member 4; The rollers 9 and 10 are pivotally supported on the shaft 12, and the rollers 11 are pivotally supported on the shaft 13. The shafts 12, 13, and 18 are shafts that are parallel to the core member 6 and supported by the base member 100. The shaft 12 is located on the rear side, and the shaft 13 is located on the front side. The rollers 9 and 10 are integrally joined, and the roller 9 has a larger diameter than the roller 10. The roller 9 is a roller that winds up the belt-like member 5, and the roller 11 follows the roller 9 to guide the belt-like member 5. The roller 10 is a roller that winds the linear member 14 extending from the arm member 3. A weight 16 is attached to the end of the belt-like member 5. The arm member 3 extends on both sides of the shaft 18, the rear end extends to the inside of the cover member 4, and the linear member 14 is attached, and the front end extends to the outside of the cover member 4 to hold the pressing member 7. Is supported by a shaft 15 so as to be swingable. Between the arm member 3 and the cover member 4, a biasing member (torsion spring) 8 that biases the front side of the arm member 3 (the side of the pressing member 7) to a standby position in which the arm member 3 is lifted is provided. The position of the arm member 3 in FIG. 1B is a standby position urged by the elastic force of the urging member 8. The pressing member 7 is Z-shaped in a side view, and a cutting blade 17 is attached to the tip.

FIG. 2A shows the cover member 4 in a state where the roll paper P is removed and lifted around the shaft 19. Due to the weight 16, the belt-like member 5 hangs vertically from the roller 11. The position of the roller 11 is preferably slightly rear (on the left side in the drawing) rather than just above the core member 6. When it is closer to the front side (pressing member 7 side) than the core member 6, it becomes difficult to load the roll paper P into the core member 6. In FIG. 2B, the pressing member 7 of the arm member 3 swings on the shaft 18, but the lower limit position is a solid line position shown in the figure. In this position, the pressing member 7 collides with the stopper 3a of the arm member 3 and cannot be lowered further.

In FIG. 1, as an example of using the linear member 14 and the roller 10 as the means for changing the swinging motion of the arm member 3 to the rotational motion to the roller 9, which means is used to change the swinging motion to the rotational motion? Such a configuration may be adopted. For example, FIG. 2C is an example in which a rod 21 provided with a gear 20 and an internal gear is used instead of the roller 10 and the linear member 14. FIG. 2D is an example in which links 22 and 23 are used instead of the roller 10 and the linear member 14.

The operation of the roll paper holder 1 will be described with reference to FIG.
FIG. 3A shows a state where the roll paper P is pulled out. In this state, the pressing member 7 is lifted by the urging member 8, and a space S is secured between the roll paper P and the pressing member 7. On the other hand, the belt-like member 5 is in a state in which the rear side (left side in the figure) of the roll paper P is slid, but the frictional force is weak against the force to pull out the roll paper P. Pulled out without resistance.

In FIG. 3B, when the required length of paper is pulled out, the pressing member 7 is pushed in the direction of arrow A. In the course of this operation, the arm member 3 swings about the shaft 18. The rear side of the arm member 3 is lifted against the elasticity of the biasing member 8, while the roller 9 is biased by the weight 16 so as to rotate around the axis 12 in the clockwise direction in the figure. As the linear member 14 is loosened (arrow c), the belt-like member 5 is unwound (arrows 2 and e). The roller 11 guides the belt-shaped member 5 to the front side.

In FIG. 3C, the cutting blade 17 of the pressing member 7 is in a state of hitting the roll paper P. The paper is cut while pressing the pressing member 7 in the direction of the arrow a. The roll paper P is pressed against the core member 6 as a whole, the back is stable, and it is easy to cut.

In FIG. 3D, the pressing member 7 is released. The urging member 8 is released, and the rear side of the arm member 3 is lowered by the elastic force of the urging member 8. Pulled by the linear member 14 (arrow H), the roller 10 rotates counterclockwise (arrow G). The rotation of the roller 10 is transmitted to the integral roller 9 to wind up the belt-like member 5, and the weight 16 is raised accordingly (arrow l). Since the roller 9 is larger than the roller 10, the winding length of the belt-like member 5 is longer than the rewinding length of the linear member 14. On the other hand, since the urging member 8 works so as to lift the front side of the arm member 3 and return the pressing member 7 to the original standby position, the roll paper P is separated from the pressing member 7, and the band-shaped member 5. Is in surface contact with the roll paper P in a wide range and a load is applied to the roll paper P by the weight 16, so that the belt-like member 5 rotates the roll paper P clockwise (arrow n). As a result, the cut edge of the roll paper P hangs down from the holding member 7 with a paper having a sufficient length as a margin.

Even when the diameter of the roll paper P becomes small, the belt-like member 5 can always be kept in contact with the roll paper P if the position of the roller 11 is appropriate. Further, the amount to be withdrawn as the allowance can be determined by adjusting the diameter of the roller 9 with respect to the swinging magnitude of the arm member 3. Furthermore, since the strip-shaped member 5 is in surface contact with the roll paper P in a wide range, the removal of the removal allowance is reliable, and the strip-shaped member 5 does not crush the roll paper P and leave a trace.

In the present embodiment, an example in which the base member 100 is attached to the cover member 4 by retrofitting is shown, but the cover member 4 and the base member 100 are integrated to have a function of dropping the allowance from the beginning. It may be commercialized as a roll paper holder. Further, if there is a margin between the roll paper P and the cover member 4 to increase the diameter of the roller 9 so that the belt-like member 5 can contact the back of the roll paper P, the belt-like member 5 is guided forward. A roller 11 may be present.
