BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper holder for various kinds of roll paper such as toilet paper and cooking paper.

[0002]

2. Description of the Related Art Conventionally, various shapes of paper holders for mounting various kinds of roll paper have been devised, and in particular, a paper holder capable of inserting and removing the roll paper with one touch has been put into practical use. However, since the structure of this kind of paper holder is relatively complicated, there is a problem that the manufacturing cost is high.

Therefore, the back plate attached to the wall surface, the pair of side plates protruding forward from both sides of the back plate, and the protrusions projecting inward of these side plates are integrally molded with a synthetic resin or the like to manufacture the paper holder. Is being considered. FIG. 5 is a perspective view showing a configuration of a conventional paper holder for roll paper such as toilet paper, showing an example thereof.

In FIG. 5, 11 is a holder, 12 is a back plate attached to the wall surface of a toilet or sink, 13 is a side plate, 14 is a paper cutter pivotally supported at the upper back of the side plate 13, and 15 is the side plate. Roll paper locking projections 13 are provided at appropriate positions 13, reference numeral 16 is a substantially horizontal U-shaped cutout provided around the projection 15, and 17 is a tongue-shaped portion formed by the cutout 16.

The paper holder 11 includes a back plate 12,
The side plate 13 and the projections 15 can be integrally formed of synthetic resin,
The production cost can be reduced. Further, since the tip end 15a of the protrusion 15 is an inclined surface in which the upper portion of the protrusion protrudes from the lower portion, the tongue portion 17 tilts outward by raising the old roll paper from the bottom when replacing the roll paper. Then, the roll paper can be easily taken out, and by inserting a new roll paper so as to lift it from below the protrusion 15, the tongue portion 17 tilts outward and the roll paper can be mounted.

[0006]

However, in this conventional paper holder, the notch 16 is formed in a lateral U shape, and the tongue-shaped portion 17 extends in the lateral direction. The load of the roll paper applied downward at the tip portion 17b becomes a large rotational moment and a twisting force at the base portion 17a of the tongue-shaped portion 17 and exerts a large load on the base portion 17a, so that the resin in the base portion 17a is aged or destroyed. Was the cause of. Therefore, the resin constituting the tongue 17 must have a hardness that can withstand the rotational moment and the twisting force.

However, on the other hand, the tongue 17 must be sufficiently tilted when the roll paper is attached / detached, and the
If 7 is too hard, it becomes difficult to replace the roll paper. That is, in the conventional paper holder, there is a drawback in that the operability and the durability cannot be achieved at the same time, the one that is easy to handle is fragile, and the one having excellent durability has the poor operability.

The present invention has been made in consideration of such circumstances, and provides a paper holder which is useful and has a high durability while having a simple structure which is extremely easy and does not increase the production cost. The purpose is to do.

In the paper holder of the present invention, a paper integrally having a back plate attached to a wall surface, a pair of side plates projecting forward from both sides of the back plate, and projections projecting inside the side plates. In the holder, a tongue-shaped portion is formed by forming substantially U-shaped cutouts around the protrusion, and the protrusion is provided below the tongue-shaped portion that can be tilted by elastic deformation. By making the tip of the slanted surface, the upper part of which projects from the lower part, it is possible to minimize the rotational moment applied to the tongue by the load of the roll paper applied to the protrusion due to the structure. Fatigue and breakage can be prevented, so that the material of the tongue is not required to be too hard. Therefore, when the roll paper is attached or detached, by lifting the roll paper to the upper part, the roll paper slides on the inclined surface, and the tongue portion can be easily tilted outward. The operation is extremely easy. In addition, the vertical cross-sectional shape of the protrusion

1 to 3 are views showing a first embodiment of a paper holder of the present invention, FIG. 1 is a perspective view, FIG. 2 is a partially cut vertical front view, and FIG. 3 is a vertical side view. Is.

In these figures, 1 is a paper holder for roll paper such as toilet paper, 2 is a back plate attached to the wall surface of a toilet or sink with screws 2a, and 3 are left and right end portions of the back plate 2. A protruding side plate 4, a paper cutter 4 pivotally supported at the inner rear portion of the upper side plate 3, a protrusion 5 for locking a roll sheet protruding in a proper position inside the side plate 3, and a protrusion 6 provided around the protrusion 5. Abbreviation U
The notch 7 is a tongue formed by the notch 6 so as to hang down in a substantially U-shape.
The side plate 3, the protrusion 5, and the tongue portion 7 are integrally molded of synthetic resin.

The projection 5 is located at the lower end of the tongue 7 and the tip thereof is an inclined surface 5a from which the upper part of the projection 5 projects from the lower part. And, this protrusion 5
The cross-sectional shape cut along the plane parallel to 7 is a horizontal E shape (Fig. 3).
See) . Therefore, the flat surface portion is not dented (sink) at the forming stage and the appearance is not deteriorated, and it is possible to finish it neatly by a simple forming method, and to reduce the contact area between the inclined surface 5a and the roll paper. It can be made small, and slippage between the inclined surface 5a and the roll paper is improved.

The notch 6 is curved at its end 6a so as to draw an arc outward, and the width of the tongue 7 is widened at its base 7a.
Therefore, the force applied to the projections 5 is not concentrated on the base 7a to be deformed, and the tongue 7 does not fatigue. Further, the tongue-shaped portion 7 is not damaged at the base portion 7a under the influence of the deterioration of the tongue-shaped portion 7 and has excellent durability.

In the above-mentioned paper holder, when replacing the toilet paper (roll paper) not shown, the old roll paper is lifted up and taken out, and the new roll paper is inserted so as to be lifted up from the bottom. However, at this time, the edge of each roll paper and the inclined surface 5 of the projection 5
By sliding with a, a force is applied to the protrusion 5 in the direction of pushing it outward, so the tongue 7 needs to tilt in the direction indicated by the imaginary line arrow A. When the roll paper is attached, all the loads of the roll paper and the paper cutter 4 are applied to the projections 5 in the downward direction.

Therefore, as in the above configuration, the tongue-shaped portion 7 is formed so as to hang down in a substantially U-shape, and the projection 5 is formed at the lower end portion thereof, so that the tongue-shaped portion is replaced when the roll paper is replaced. The structure in which the roll paper 7 is sufficiently tilted in the direction of the imaginary line arrow A to facilitate the replacement of the roll paper, and at the same time, the stress against the downward force is large, and the load of the roll paper and the paper cutter 4 can be sufficiently endured. Has become. Further, since all the loads of the roll paper and the paper cutter 4 are applied downward, no torsional force is applied to the tongue 7.

Further, since the tongue 7 is prone to tilt only in the direction shown by the imaginary line arrow A, even if an external force is applied to the protrusion 5 in the direction of the double arrow B, the tongue 7 will not move. It is stable without deformation and fatigue.

In addition to the structure of the first embodiment described above, a corrugated plate forming portion formed in parallel with the horizontal direction may be provided on the upper peripheral edge of the tongue portion 7. FIG. 4 is a partially vertical front view showing a paper holder according to a second embodiment of the present invention. In this figure, the members denoted by the same reference numerals as those in FIGS. 1 to 3 are the same or equivalent members.

In FIG. 4, reference numeral 7b denotes a corrugated plate forming portion which is formed in parallel with the upper peripheral edge of the tongue-shaped portion 7 in the horizontal direction. By providing the corrugated plate forming portion 7b, the tongue-shaped portion 7 has an arrow A. It is configured so that it can be more easily tilted only in the direction indicated by.

Therefore, with this structure, the arrow A can be used without changing the material forming the tongue portion 7.
Only the tilting of the direction can be facilitated, and the operability of the paper holder 1 can be further improved. In addition, the apparent length of the tongue 7 can be shortened, the outer shape of the paper holder 1 can be freely set, and the length of the tongue 7 can be shortened. A large rotational moment is not applied to the base 7a of the tongue 7, and the durability of the paper holder 1 can be further improved.

[0027] That is, since the corrugated sheet forming part of easily tilted by 7b is only with respect to the direction shown in arrow A, as external force is applied in the longitudinal direction not only downward relative to the protrusion 5 Also, the tongue 7 is not deformed or fatigued, and the tongue 7 is not deformed or fatigued,
Very stable.

In each of the above embodiments, the cutout 6
The end portion 6a of the is curved outward so as to draw an arc so that the tongue portion 7 is not subjected to a local force, but the present invention is not limited to this. However, it goes without saying that the cutout 6 may have various shapes, for example, the tongue-shaped portion 7 may be provided so as to have a substantially inverted trapezoidal shape.

[0029]

As described above, in the paper holder of the present invention, the vertical cross section of the projection is formed in a horizontal E shape.
At the same time, a substantially U-shaped notch is provided around each of the protrusions to form a tongue-shaped portion, and thus the protrusion is provided below the tongue-shaped portion that can be tilted by elastic deformation, and the tip of the protrusion is , The upper part of the tongue has an inclined surface protruding from the lower part, so that the rotational moment applied to the base of the tongue by the load of the roll paper applied to this protrusion is minimized and no force is applied in the twisting direction. It is possible to prevent fatigue and breakage of the roll-shaped portion, and when the roll paper is attached or detached, by lifting the roll paper to the upper part, the roll paper slides on the inclined surface and tilts the tongue-shaped portion to the outside. The operation of attaching and detaching paper can be performed very easily.

Further, the vertical cross-sectional shape of the protrusion is a horizontal E-shape.
The tongue portion is formed by forming substantially U-shaped notches around the protrusion, and the tongue portion is formed below the tongue portion that is tiltable by elastic deformation. By making the tip of the sloping surface so that the upper part projects from the lower part, it is possible to minimize the rotational moment applied to the tongue by the load of the roll paper applied to this projection and to apply a force in the twisting direction. Without
Fatigue and breakage of the tongue can be prevented, and when the roll paper is attached or detached, by lifting the roll paper to the upper side, the roll paper slides on the inclined surface and tilts the tongue outward, The roll paper can be attached and detached very easily, and by providing the corrugated plate forming portion on the upper peripheral edge of the tongue, the surface area of the tongue can be increased, and the tongue can be easily made. It can be formed to be tiltable.

Therefore, the tongue-shaped portion can be shortened in the apparent length in the vertical direction and can be made compact as a whole, and the projection and the tongue-shaped portion provided at the lower portion of the tongue-shaped portion can be made compact. Since the distance from the base portion is shortened, the rotational moment applied to the tongue portion by the load applied to the protrusion and the external force applied to the front and back can be minimized, and fatigue and breakage of the tongue portion can be effectively prevented. Also, with the inclined surface
By minimizing the contact area with the roll paper,
While reducing the frictional resistance during the paper insertion / removal operation,
You can finish it neatly without any trouble during production.
You.

Further, when the end of the notch is widened outward at the upper part of the tongue to increase the width at the upper end of the tongue, the rotation moment applied to the base of the tongue is increased. It is possible to prevent fatigue and fracture more effectively without concentrating on one point.
