Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll sheet holder for holding toilet paper and other papers, cloths, non-woven fabrics, films, metal sheets and roll sheets.

[0002]

2. Description of the Related Art Generally, a toilet roll seat holder is composed of a holder main body having a pair of brackets having a roll shaft for supporting toilet paper and a seat cover. The bracket holds the seat cover rotatably up and down, the cover covers the upper peripheral surface of the toilet paper supported between the brackets, and the paper pulled out between the roll and the seat cover is attached to the tip of the seat cover. It is designed to cut at the edge.

[0003]

Since the cover is simply pressed down onto the roll paper by its own weight, the sheet cover must be held by the fingers of one hand when cutting the drawn paper. , I needed both hands to operate it.

However, apart from the fact that the toilet is a narrow space in which movement is restricted, if the user can use both hands freely, no particular problem will occur, but there are persons with disabilities, the elderly, and others. For some reason, operation of both hands is extremely difficult for a person with one hand or a handicapped person or a person with impaired hand function.

Needless to say, it is desirable that even a healthy person who can use both hands freely can operate with one hand. Another problem in handling the seat cover of the roll sheet holder is the problem of the edge of the seat cover. The edge of the seat cover also serves as a guide to prevent the paper from breaking, so that each time you use the toilet paper, when pulling out the paper to the required length, you need to use the right hand, like an elderly person with poor hand function. For those who can't handle it, it's non-ergonomics. This point is exactly the same for other roll sheets.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a roll sheet holder having a structure in which the sheet can be cut by one-handed operation, the danger of the edge of the seat cover is eliminated, and the roll sheet can be smoothly delivered.

[0007]

In order to achieve the above object, a roll sheet holder according to the present invention has a holder main body and a seat cover, and a roll sheet supported by the holder main body is forcibly forced by the seat cover. A roll sheet holder for pressing and cutting a roll sheet pulled out along an edge of a seat cover, wherein a holder main body has a pair of brackets, and the pair of brackets are arranged facing each other at regular intervals. It is provided with a roll shaft and a spring, and the roll shaft supports the roll sheet between both brackets, and the spring forcibly presses the seat cover to urge it downward, and at least The seat cover is attached to one of the brackets, and the seat cover is pivotally supported so as to extend and retract between the brackets, and its pivot is connected to the spring. Than it is.

The spring is a rod-shaped or plate-shaped elastic body, which is bent in the longitudinal direction and has one end attached to the bracket and the other end attached to the pivot of the seat cover, and the deflection direction is reversed during the rotation of the pivot. Then, the action direction of the spring is switched between the upright direction of the seat cover and the rolling direction of the roll sheet.

The spring is an elastomer,
The bending restoring force and the compressive deformation restoring force apply a torque in the upright direction or the rolling direction to the seat cover.

Further, the seat cover has a cutter,
The cutter has a continuous rectangular shape formed along the edge of the surface on the side where the roll sheet is pulled out, and is 1.5 mm or more,
It is an uneven edge having a pitch of 2.5 mm or less.

The cutter is located inside the edge of the sheet cover on the roll sheet pull-out side and on the locus of an arc that is in contact with the outer diameter of the core of the roll sheet around the pivot axis of the sheet cover.

Further, the seat cover has a cutting auxiliary guide, and the cutting auxiliary guide is formed so as to project in parallel to the inside of the cutter at an overhanging height higher than the cutter, and contacts with a part of the outer layer of the sheet roll. This is to prevent contact between the roll sheet drawn out to the cutter and the cutter.

Further, the cutting auxiliary guide is located in a region between an arc passing through the axis of the roll shaft centering on the pivot axis of the seat cover and an arc contacting the outer periphery of the core of the roll sheet.

Further, the seat cover has a slide guide, and the slide guide is formed in parallel with the curved surface of the seat cover along the pull-out direction of the roll sheet.

The cross-sectional shape of the slide guide is trapezoidal, and the top surface of the narrow trapezoid which is the contact surface of the roll sheet is mirror-finished.

[0016]

The seat cover is forcibly pressed down by the spring force on the surface of the roll sheet, and the pressure necessary for cutting the sheet pulled out from the roll sheet is obtained at the edge. In addition, a bar-shaped or plate-shaped spring is used as the spring for urging the seat cover, and the biasing direction of the spring force is reversed during the rotation of the pivot of the cover, so that when the seat cover is pulled up above a certain angle, Is pushed up by the standing posture,
It is easy to remove the roll sheet core and attach the replenishment roll sheet, and the ergonomics are high. Further, when the spring is made of a flexible elastomer, the restoring force of the bending deformation and the restoring force of the compressive deformation effectively act to obtain a strong torque in the rolling direction and the standing direction of the seat cover.

The roll sheet is pressed down by the sheet cover and pulled out along the guide. The cutter attached to the edge of the sheet cover that cuts the sheet is safe because there is no sharp edge because of the continuous rectangular uneven edge.

Although the roll sheet is pressed by the sheet cover urged by the spring, when the roll sheet is pulled out, the cutting assist guide is used regardless of the winding diameter of the roll sheet. Also, it is possible to hold the pulled-out roll sheet by being supported by the slide guide and not contacting the cutter, and cut it by the cutter when pulling it up. In the slide guide, the trapezoidal top surface is the contact surface with the roll sheet, the contact area is small, and because the top surface is a mirror surface, it is slippery, and the roll diameter decreases and the sheet relative to the outer diameter of the roll sheet. Even if the relational angle of the cover changes a little, the relational position between the roll sheet and the slide guide does not shift.

[0019]

EXAMPLE An example in which the present invention is applied to a toilet roll sheet holder will be described below with reference to the drawings.

1 to 3, a roll sheet holder according to the present invention comprises a holder body 1 and a seat cover 2.
It consists of and. The holder main body 1 is composed of a pair of casing-type brackets 3 and 3 and a back plate 4 that connects the brackets 3 and 3, and each of the brackets 3 and 3 is provided with a roll of toilet paper on its facing surface. A supporting roll shaft 5 is mounted so that it can be erected. The roll shaft 5 is
A spring force is applied to maintain the inverted posture in which the paper rolls out horizontally, and when the roll paper is loaded, it is pushed up in the standing direction by the roll paper loaded from below, and after loading, the roll paper returns to the inverted posture. Although it supports the pipe, its structure is conventionally known, and therefore detailed description thereof is omitted.

The seat cover 2 is pivotably supported by both brackets 3 and 3 so that the seat cover 2 is pivotable. The pivot 6 of the seat cover 2 is connected to a spring 7 built in the bracket 3.

As shown in FIG. 4, the spring is formed by processing an elastomer into a rod shape or a plate shape, has bearing portions 8a and 8b at both upper and lower ends, and has a smooth curved edge in the central region in the longitudinal direction, A thick portion 9 is formed, and neck portions 10a and 10b are formed near the bearing portions 8a and 8b, respectively. The shape of the spring 7 cannot be specified uniformly depending on the material of the elastomer, but the function curve shape is designed in consideration of the operating angle of the cover and the conversion point of the torque direction. In the examples, an ester elastomer was used to design the shape as shown in FIG.

In FIG. 5, the spring 7 is housed in the housing of the bracket 3, the upper end bearing portion 8a is connected to the pivot 6, and the lower end bearing portion 8b is bent slightly in one of the longitudinal directions.
Is pivotally supported by the pin 11 obliquely below and planted in the bracket 3.

Also, the neck 10b near the lower end bearing 8b
A pair of stoppers 12 are provided on both sides of the spring to restrain the lower end portion of the spring 7. FIG. 5 shows a state in which the seat cover 2 is biased downward, that is, a state in which the roll paper R is pressed down. In this state, the restoring force mainly due to the bending of the thick portion 9 at the center becomes a rotational force, which acts on the bending portion of the upper neck 10a, and the restoring force due to the compressive deformation of the neck 10a is further applied to the pivot 6 in the figure. A clockwise rotation torque is applied to effectively reduce the seat cover 2.

FIG. 6 shows a situation in which the sheet cover 2 is erected upward and the upper portion of the roll paper R is opened. When the seat cover 2 is turned upward, the spring 7 still urges the seat cover 2 downward within a certain range during the turning, but pushes the seat cover 2 upward against the spring force. At this time, the spring 7 reverses the bending direction and reverses the acting direction of the spring force to urge the seat cover 2 upward. In the figure, 13 is a stopper body. When the spring 7 of the embodiment is used, when the thick portion 9 at the center becomes substantially linear, it is brought into contact with the stopper body 13 to maintain its posture. In this posture, the upper neck 10a is only bent at a sharp angle as shown in the figure,
The thick portion 9 is supported by the stopper body 13 and does not generate a repulsive force, and the restoring force due to the bending deformation of the neck 10a does not act on the pivot 6 of the roll sheet holder 2. This means that the seat cover 2 is not flipped up by a strong force.

In the above embodiments, the workability and characteristics of the elastomer are used to control the elasticity of each part in the longitudinal direction by changing the shape, but the spring is not necessarily limited to this shape. Further, the material is not limited to the elastomer, and rod-shaped or plate-shaped metal springs may be used. Even in the case of a metal spring, the elastic coefficient can be partially changed by changing the thickness or width, or by combining two or more springs.

By using a rod-shaped or plate-shaped spring, the urging direction of the spring can be converted into two directions by utilizing the reversal of the bending direction. What is important in the present invention is the cutting of the drawn paper. Since the pressure of the seat cover required for the above is obtained by the spring force, it is not always necessary to switch the biasing direction of the spring between the two directions.

In the present invention, in order to easily cut the roll paper, a cutter 14 is provided on the pressure surface of the seat cover 2 as shown in FIG. 8, and a cutting auxiliary guide 15 for guiding the roll paper. And a slide guide 16. As shown in FIG. 8, the cutter 14 is a continuous rectangular concave-convex edge formed inside the cover along the edge of the cover when viewed from the front.

As shown in FIG. 9, the cross section of the seat cover 2 has a quadratic curve having a diameter larger than the maximum diameter of the paper roll, and is curved in the direction of the roll shaft 5 toward the edge, and the cutter 14 Is located on the locus of an arc that is in contact with the outer diameter of the winding core S of the roll paper R with the pivot 6 as the center, and the relational position with respect to the outer diameter of the roll paper R is constant regardless of the size of the winding diameter of the roll paper R. I keep it.

Normally, the roll paper is cut while being torn at the edge of the sheet cover 2, but in the present invention,
The paper is cut while being perforated by the right angle of the step of the unevenness. The uneven edge is safe because it does not have a point like saw teeth. However, in order to easily perform cutting at the concave and convex edges of the cutter, it is desirable to narrow the width of the concave and convex edges on the upstream side in the roll paper withdrawing direction and substantially enlarge the interval between the convex edges. .

The cutting auxiliary guide 15 is for preventing contact between the roll paper and the cutter 14 during the operation of pulling out the roll paper R, and is formed so as to project in parallel with the inside of the cutter 14 and project. is there. The overhang height is higher than that of the cutter 14, and when the roll paper is toilet paper, it is set to 2 mm or more, which is less than the average length of the pulp fiber length.

The cutting auxiliary guide 15 is a pad that substantially presses the roll paper R, and as shown in FIG. 9, an arc passing through the axis of the roll shaft 5 about the pivot 6 of the seat cover 2 and the roll paper R. It should be formed in a region as close to the cutter 14 as possible in a region between the arc and the outer circumference of the winding core S.

As shown in FIG. 7A, the slide guide 16 is a ridge provided in a row over the entire width of the pressure surface of the seat cover 2. The cross-sectional shape is trapezoidal as shown in FIG. 7C, and the narrow top surface 16a of the trapezoid is the contact surface of the roll paper and rises along the curved surface of the seat cover 2,
The top surface is integrally connected at the same height as the auxiliary guide 15 and is mirror-finished with an accuracy of 0.8 μRmax or more to reduce the friction resistance of the roll paper and prevent the generation of friction noise. Further, between the trapezoidal top surface 16a of the slide guide 16 and the ridge line surface 16b which is the rising surface,
Being chamfered with a radius as small as 0.5 mm or less prevents the increase of the breaking strength of the multiple wrinkles of the pulp caused by the fine deviation of the paper when cutting the roll paper, The initial breaking effect is promoted.

By attaching the slide guide 16 to the seat cover 2, the roll paper is easily cut even if the roll diameter changes and the contact position between the paper and the seat cover moves due to the use of the roll paper.

[0035]

As described above, according to the present invention, the pulled-out paper can be cut without pressing the upper surface of the roll sheet holder with one hand, and when the paper is cut, it is provided at the edge of the roll sheet holder. With a rectangular concave-convex cutter, you can easily cut without difficulty. Therefore, according to the present invention,
You can pull out with one hand and use toilet paper,
Even a handicapped person with one handed hand or an elderly person with impaired finger function can operate without difficulty, and at the same time useless consumption of paper can be eliminated.

In the above examples, the example of application to a toilet roll sheet holder has been shown, but in addition to roll paper such as paper towels using paper and non-woven fabric, kitchen paper, medical paper, and paper towels used in factories, The same applies to roll sheet holders for films such as Saran wrap, aluminum foil, and other metal sheets.
