Description

The present invention relates to a roll paper holder for cutting, for example, toilet paper with one hand.

Conventionally, in the roll paper holder for cutting toilet paper, etc., from the viewpoint of hygiene and convenience, it can be easily cut with only one hand, and the cut part is not hidden by the paper cutter, so it can be grasped as it is and continuously pulled out. Roll paper holders that can be cut have been proposed.

As a roll paper holder of this kind, the one disclosed in Patent Document 1 is known.

In this roll paper holder, when a load is applied to the cut bar, the stopper appears and disappears from the inside of the support cylinder that holds the roll paper to hold down the roll paper. By pressing the cylinder core, the paper can be cut reliably.

However, in the roll paper holder disclosed in the literature, the mechanism is complicated, the number of parts is large, and the roll paper holder cannot be manufactured inexpensively. Furthermore, as the amount of paper decreases, the cut paper is closer to the cut bar, and the cut bar becomes an obstacle the next time the paper is grabbed. In addition, since the support shaft of the stopper is inside the support cylinder and cannot keep a distance from the stopper, the stopper does not function unless the cut bar is moved significantly, which makes it difficult for the user to understand how to use the stopper. ..

The present invention has been made in view of the above, and regardless of the remaining amount of paper, it is easy to grasp the paper, the paper can be cut reliably and easily with one hand, and the mechanism is simplified to make it inexpensive and in shape. The purpose is to provide roll paper holders that are versatile and have excellent design.

In order to solve the above problems, the roll paper holder according to the present invention is a roll paper having a fixing portion for attaching to a wall surface or the like and a roll paper holding portion inserted into a cylinder core for holding the roll paper. It is equipped with a holder support, a paper cutter, and a paper cutting mechanism having a rotation restraining part for giving resistance to the cylinder core to stop the rotation of the roll paper when cutting the roll paper , and the paper cutting mechanism is a paper cut. A roll paper holder connected to a roll paper holder support with the mechanism support as the center of rotation, characterized in that the roll paper holder support and the paper cutting mechanism are each made of one plate-shaped material. It is a roll paper holder.

Also, in the configuration, in addition to the paper cutting mechanism support portion, but has a rotation inhibiting portion guide for limiting the movement of the rotation suppressing part to the central axis of the cylinder core.

According to the present invention, the paper can be easily grasped with one hand and can be cut reliably and easily with one hand regardless of the remaining amount of the paper. Further, by simplifying the mechanism, it is possible to provide a roll paper holder that is inexpensive, has a variety of shapes, and is excellent in design.

It is a perspective view of the roll paper holder which concerns on embodiment of this invention. It is a perspective view of the roll paper holder support which concerns on embodiment of this invention. It is a perspective view of the paper cutting mechanism which concerns on embodiment of this invention .

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of a roll paper holder according to the present invention. The fixing portion 3 shows a state in which the roll paper holder is fixed to a wall surface or the like.

In a general roll paper holder, a roll paper cover that suppresses the rotation of the roll paper 30 and cuts the paper 31 at the time of pulling out the paper is often used, but in the present invention, the roll paper cover is not required. Therefore, when replacing the roll paper 30, it is not necessary to lift the roll paper cover one by one, which is very convenient. Of course, there is no problem in adding a roll paper cover to the present invention for the purpose of design and other purposes.

Here, the roll paper holding portion 4 and the rotation suppressing portion 5 are made in a size that fits in the cylinder core 20 of the roll paper. As can be seen from FIG. 1, the roll paper 30 can be easily taken in and out simply by inserting it from the side. Then, if the edge of the roll paper holding portion 4 is appropriately inclined or has a step, it is possible to prevent the roll paper 30 from falling off during use .

As can be seen in FIG. 1, in order to cut the paper, first, the paper 31 is pulled out by a desired amount, pulled up, and applied to the paper cutter 6. If it is pulled up as it is, the paper cutter 6 is raised together by the force of pulling up, and the rotation suppressing portion 5 is lowered with the paper cutting mechanism support portion 7 as the center of rotation and comes into contact with the cylinder core 20 .

Then, the rotation of the roll paper 30 is stopped by the contact of the rotation suppressing portion 5, and the paper cannot be pulled out, so that the paper 31 is cut by the paper cutter 6. When the paper 31 is cut, the load on the paper cutter 6 is removed, so that the paper cutter 6 is lowered and the rotation suppressing portion 5 is raised . At this time, the paper 31 is in a hanging state, and since there is a distance between the paper cutter 6 and the roll paper 30, the paper 31 can be continuously grasped and pulled out. The amount of sagging can be determined by the positional relationship between the roll paper 30 and the paper cutter 6.

Although the paper cutter 6 is shown here with a straight blade, it may have a saw blade shape in order to make the cutting more reliable.

The force applied by the rotation suppressing portion 5 to the cylinder core 20 is determined by the position of the paper cutting mechanism support portion 7 and the frictional resistance of the rotation suppressing portion 5. Therefore, if a material having a high frictional resistance such as a silicone resin is used for the surface of the rotation suppressing portion 5, the rotation of the roll paper 30 can be suppressed more reliably. Further, when the position of the paper cutting mechanism support portion 7 is closer to the rotation suppressing portion 5 than the center of the rotation suppressing portion 5 and the paper cutter 6, the force applied to the paper cutter 6 is larger than the force applied to the paper cutter 6 due to the difference in the moment of force. Can be added to the cylinder core 20. However, if it is too close, the movement of the paper cutter 6 at the time of cutting becomes large and a sense of discomfort occurs. Therefore, it is preferable that the paper cutting mechanism support portion 7 is located closer to the paper cutter 6 than the cylinder core 20.

If the weight of the paper cutter 6 is made sufficiently heavier than the rotation suppressing portion 5, the position of the paper cutting mechanism support portion 7 can be set closer to the paper cutter 6 than the center, and the movement of the paper cutter 6 can be made smaller. In this case, it is better to devise to increase the frictional resistance of the rotation suppressing portion 5.

Further, the roll paper holding portion 4 may be a general rod-shaped one, but a plate- shaped one having a shape of contacting the cylinder core 20 at two points in the inner circumferential direction of the cylinder core 20 is preferable. If it is rod-shaped and has only one contact in the cylinder core 20, the roll paper 30 may shake when the paper 31 is pulled out and come into contact with the rotation suppressing portion 5. As shown in the figure, if the plate-shaped two-point contact is used, the center of gravity is stable, and when the paper 31 is pulled out, shaking is unlikely to occur. It will be pressed with, and it will be very stable. Further, an appropriate frictional resistance can be given when the paper 31 is pulled out .

FIG. 2 is a perspective view showing the paper holder support 1 according to the present embodiment. FIG. 3 is a perspective view showing the paper cutting mechanism 2 according to the embodiment. The opening 11 in the paper cutting mechanism 2 has an elliptical shape, the major axis thereof is slightly larger than the width of the protrusion 10 in the paper holder support 1 in the height direction, and the minor axis is slightly smaller. As a result, when the paper cutting mechanism 2 is raised 90 degrees, the opening 11 is inserted into the protrusion 10 and turned 90 degrees to return to the original state . As shown in FIG. 1 , the paper holder support does not come off. 1 and the paper cutting mechanism 2 can be connected. The shapes of the protrusions 10 and the openings 11 and the method of preventing them from falling off are not limited to this embodiment. For example, the opening width of the openings 11 becomes smaller when the protrusions 10 are moved from the insertion position to the support position. It may have a shape, or a member for preventing falling off may be attached to the protrusion after insertion.

Here, the paper cutting mechanism positioning portion 8 may be anywhere as long as it is a part of the roll paper holder support 1, for example, a protrusion is provided on the rotation suppressing portion 5, and the paper cutting mechanism positioning portion 8 comes into contact with the roll paper holding portion 4 and stands still. In this case, the contact point of the roll paper holding portion 4 becomes the paper cutting mechanism positioning portion 8.

In the present embodiment, in the paper cutting mechanism support portion 7a, since the paper cutting mechanism 2 is only mounted on the roll paper holder support 1, the rotation suppressing portion 5 can easily move left and right. In order to avoid this, it is preferable to provide the rotation suppressing portion guide 9. In this embodiment, the rotation suppressing portion guide 9 is attached to only one side in a form of being in direct contact with the rotation suppressing portion 5 , but of course, it may be attached to both sides, or it may be attached to a position away from the rotation suppressing portion 5. Further, it is preferable that the rotation suppressing portion 5 is rounded so as not to be caught when the roll paper 30 is inserted.

The most important thing in this embodiment is that both the roll paper holder support 1 and the paper cutting mechanism 2 can be configured by using one plate each. In each production, one plate may be cut and bent. Further, since it is not necessary to attach a connecting part such as a hinge and it is simply fitted, the material cost and the assembly cost can be very low.

Further, since the paper cutting mechanism 2 can be easily removed, it is easy to clean and maintain it, and it is very convenient when it is bent or rusted and you want to replace it. Another advantage is that the paper cut mechanism 2 can be used to make various designs and can be attached to and replaced with the same roll paper holder support 1.

As described above, the roll paper holder according to the present invention is easy to grasp the paper regardless of the remaining amount of the paper, can cut the paper reliably and easily with one hand, and is inexpensive and has a shape by simplifying the mechanism. It has a variety of designs and is excellent in design.
