Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll paper holder that holds a roll-shaped sheet material such as a roll paper such as toilet paper or a nonwoven fabric.

The toilet paper holder, which is a typical example of a roll paper holder, is a holder that enables the engagement/disengagement operation of the toilet paper by a linear reciprocating operation of the roll body in the front-back direction with one hand. The toilet paper can be detachably attached by the urging elastic force of the support body to the part and can be set rotatably so that the toilet paper can be set in the holder to prevent the roll body from being pulled out when the paper is pulled out and to be stable. Patent Documents 1 and 2 are well known as toilet paper holders provided with various holding devices. Further, not only the apparatus for holding the roll body of the present invention, but after tensioning the paper to pull the sawtooth-shaped blade edge and cutting it, the apparatus that eliminates the phenomenon that the cutting edge adheres to the blade edge is used. Patent Documents 3 and 4 are well-known as a toilet paper holder provided with a cutting device that separates the paper from the cutting edge by utilizing the.

JP, 2006-149421, A Japanese Utility Model Publication No. 48-20742 Japanese Unexamined Patent Publication No. 2000-041891 JP, 2003-24241, A

A problem in the technology of elastically holding the roll body to the opening of the cylinder core of the roll body by the biasing elastic force of the support body is that the width dimension of the roll body and the inner diameter dimension of the roll body core cylinder vary depending on the manufacturer. It is to hold the toilet paper stably in response to changes in the distance between the bodies. In Patent Document 1 described above, the elastic force of an elastic spring that elastically holds the toilet paper does not inadvertently remove the cylinder core of the roll body from the support body when the paper is pulled out, and also removes the used cylinder core. It is described that the outer edge of the roll body cylinder core can be tightly held by the guide inclined surfaces of the left and right bearings (see Patent Document 1). However, the structure is complicated and there is a problem in manufacturing cost.

In the holder of Patent Document 2, even if there is a slight change in the width of the roll body, the separation distance between the holding units that elastically bias the support body toward the roll body can be adjusted, so that the toilet paper can be used without any trouble. There is an explanation that it will be retained. However, the outer surface of the bulging portion of the support body is formed in a tapered shape as much as possible.Therefore, there is no consideration for variations in the inner diameter of the cylinder core, and the roll body cannot be engaged depending on the inner diameter of the cylinder core. There is a possibility that the paper roll may be broken during the drawing of the paper due to excessive rotation resistance given to the roll body, the rotation of the roll body may be unstable, or the paper may be removed from the support body. Further, since the bulging portion has a sharpened shape, the frictional friction at the time of engaging and disengaging the roll body is large and the operability is not good.

Further, in the technology for preventing the cutting edge of the paper from adhering to the blade edge, which is accompanied by the present invention, the roll paper holder disclosed in Patent Document 3 includes a cutting blade in the holder body and is rotatably pivotally supported. It is said that an elastic member is provided on the back surface of the extended portion, and the tension generated by the paper surface that is pulled out is used to prevent the adhesion of the paper by the restoring force of the elastic member that is pressed at the same time as the cutting of the paper. However, the tension due to the friction generated on the paper surface when the paper is pulled out is weak and the paper may not be cut or the elastic member may not be pressed sufficiently.

In addition, in the roll paper holder specified in Patent Document 4, a cutter and a curving member that separates the paper attached to the cutter are provided side by side at the tip of the cover plate, and the end of the paper cutter plate is a roll body. While the outer peripheral surface is always pressed, tension is applied to the paper that is pulled out by limiting the rotation of the roll body, and the curving and deforming member is bent and cut by the tension, and then the curving and deforming member is restored to prevent the adhesion of paper. However, as the remaining amount of roll paper decreases, the angle of the cutting edge changes with respect to the paper surface that is pulled out, the paper surface does not contact the cutting edge, the paper is not cut normally, and the cover plate floats. There is a risk of

The present invention has been made in view of such circumstances, and a roll paper holder capable of stably holding the toilet paper and applying an appropriate tension to the drawn paper, and cutting the paper by the tension. Equipped with an inexpensive cutting device that prevents the edge from adhering to the cutting edge, you can detach the roll body with one hand and pull out and cut the paper, it is effective for countermeasures against infectious diseases and sanitary without having to touch the holder body at all Since it is a roll paper holder, it is possible to engage and disengage the roll body by reciprocating back and forth, and it is also possible to take out the hanging paper edge in the front direction. It is possible to embed it inside a wall or to hang it under a triangular corner shelf, providing a roll paper holder that is safe and aesthetically refreshing without being an obstacle when installed in a small space such as a toilet. It is a thing.

To achieve the above object, in the roll paper holder according to claim 1, the inner edge of the opening of the roll body core is formed by a bulge portion of a pair of bearings that are provided so as to face the inside of the left and right supporting side bodies. In the holder that holds the roll body by holding the elastic pressure so that the roll body can be engaged and disengaged and is rotatably supported, the support body is a hollow cylinder having a large diameter and a short dimension close to the diameter of the roll body and a large radius of curvature at one end. It has a curved bulging part, and a flange part that extends outward is formed at the other end, and the shaft part can be inserted and retracted by inserting it into a through hole formed in the side surface of at least one support side body. And a holding device that holds the roll body so as to be rotatably held by being biased inward by the biasing means.

The urging means of the roll paper holder according to claim 2 is located outside the flange part of the support body inserted into the support side body of the roll paper holder according to claim 1 and outside the support side body. An elastic member is interposed between the pressing member and the inner surface of the pressing member that covers the collar portion.

In the roll paper holder according to claim 3, the separation distance between the left and right support side bodies that constitute the roll paper holder holding device according to claim 1 or 2 can be adjusted by screwing the support side body back and forth. It is characterized by

The roll paper holder according to claim 4 is a roll paper holder capable of cutting a paper pulled under tension from a roll body held by a holder body, and is arranged in parallel with an outer peripheral surface of the roll body. A cutting device for moving a paper pulled out to a cutting blade by contacting and cutting the paper, in which elastically deforming convex members by elastically deforming members or elastically deforming friction members are arranged in parallel and supported near the back surface of the cutting blade. The support body is fixed to the holder body, and the shape of the elastically deformable convex member is pressed and deformed by the surface of the drawn paper, and the drawn paper has a shape capable of abutting the cutting edge and the drawn paper. A toilet paper holder characterized by comprising a cutting device having a guiding means whose surface is always in contact with the cutting blade at a constant angle, which is provided in the middle of the cutting blade and the roll body.

The roll paper holder according to claim 5 is a roll paper holder capable of cutting a paper that is pulled out under tension from a roll body held by a holder body, and the pulled-out paper is hung down to a position substantially directly below the roll body. Two guide bars for guiding are installed horizontally and in parallel on the outer peripheral surface of the roll body so as to be spaced apart from each other on the left and right supporting side bodies, and are vertically swingable with both front ends of the guide bar as fulcrums. An L-shaped plate-like rocking plate with a downwardly directed tip is installed in parallel with the guide rod and is installed between the left and right supporting side bodies, and cuts the cutting rod having a cutting blade so as to cover the front surface from the upper surface. A toilet paper holder comprising a cutting device that is placed in contact with a rod.

Since the present invention employs the means as described above, it has the following effects. According to claim 1 of the present invention, the bulging portion and the shaft portion of the support body have a large diameter, and the radius of curvature of the bulging portion that elastically clamps the inner edge of the opening of the roll body cylinder core of the roll body is increased. When the roll body is engaged in the bulging part, the moving distance of the support body that appears and disappears can be reduced, so there is little effect on the clamping force due to changes in the width of the roll body or the dimensional variation of the cylinder core inner diameter. Therefore, the roll body can be held more stably. Further, the inclination of the bulging portion plays a role of guiding the roll body to the top position of the bulging portion, so that the engaging work can be performed smoothly.

According to the second aspect of the present invention, the elastic member is interposed between the flat surface of the large flange portion and the inner surface of the cover that covers the large flange portion, so that the supporting body is supported at many supporting points, so that the supporting body protrudes and retracts. The tilting of the supporting body is suppressed, the rolling body can be smoothly engaged and disengaged with almost no frictional resistance of the supporting body appearing and disappearing, which is seen in the conventional invention, and the urging means is inexpensive and has a small number of parts. Becomes

According to the third aspect of the present invention, by adjusting the separation distance between the bearings, it is possible to cope with the width of the roll paper distributed in the market and the inner dimension of the tube core that are out of the JIS standard. At the same time, it is possible to adjust the clamping force on the roll body by the support body, so that the roll body can be engaged and disengaged smoothly, and the tension can be adjusted, so it is possible to prevent intermediate breakage due to the paper quality of the roll paper, It becomes a roll paper holder that is easier to use.

According to claim 4 of the present invention, the elastic deformation convex member having a height equal to or higher than the height of the cutting blade is provided in a position close to the back surface of the cutting blade in parallel in a part or all of the longitudinal direction of the cutting blade. When the friction member that is elastically deformed is installed, the cutting end of the paper attached to the cutting edge is eliminated from being attached due to the restoring force of the elastically deforming convex member that is compressed after being cut, and the top of the friction member is As a result, rubbing friction with the pulled-out paper occurs and stronger tension is applied to the paper, so that the paper can be cut more stably. Further, the guiding means keeps the angle of contact with the cutting edge always constant after the paper surface presses the top of the elastically deforming convex member even when the remaining amount of roll paper changes, and at the same time, the bending position of the paper and the top of the convex member. By arranging the positional relationship between the blade and the cutting edge in a non-linear manner, rubbing friction with the surface of the guiding means occurs while the paper is being pulled out, a stronger tension is applied to the paper, and the paper can be stably cut. Further, since the next picking allowance is secured, picking up the paper becomes easy.

According to claim 5 of the present invention, while preventing the danger of the fingers that take in and out the paper when pulling out the paper from the cutting blade, the cutting edge of the paper is forcibly forced by the weight of the oscillating plate and the projecting piece while ensuring the picking margin.

The operation will be described. After opening the opening/closing lid 74, the paper P is pulled out from the roll body R, the end portion is inserted into the slit 78, and the roll body R is placed and closed while hanging down. Next, while pulling the end part slightly downward from the horizontal while reaching the appropriate length, the elastic convex member 7 is pressed and the cutting edge is moved upward by pulling on the cutting edge to separate the cutting edge from the cutting blade 6. Then the picking allowance is formed.

The preferred embodiment of the present invention has been described above, but it goes without saying that the present invention is not limited to the above embodiment. For example, when there is a fear that the paper P cannot be cut due to insufficient tension on the paper P generated from the holding device, a rubbing friction process is performed on the surface where the support body or the guide plate which is the guiding means of the cutting device A and the paper P surface abut. It may be applied to increase the tension. Further, an opening/closing door may be attached to the front surface of the holder main body as a measure for preventing water droplets in a shower or the like when the roll paper holders of Examples 2 and 3 are used in a unit bath.
