Description

Technical Field

[0001] The present invention relates to a simple paper cutter for a toilet paper holder. More specifically, the present invention relates to a simple paper cutter for a toilet paper holder that can easily cut toilet paper with one hand by being attached to an existing toilet paper holder.

Background Art

[0002] A toilet paper holder is attached to a wall surface such as in a toilet, and generally includes a roll paper holder, a pressing plate for cutting the roll paper, and a roll paper shaft support member (see, for example, Patent Document 1).

[0003] When pulling out and cutting the toilet paper attached to the paper holder from the paper holder, while holding down the upper surface of the pressing plate for cutting the roll paper with one hand to suppress the rotation of the roll paper, the pulled-out roll paper is cut with the other hand. Thus, since both hands are required to cut the roll paper, it is difficult for a physically handicapped person with a disabled hand to cut the roll paper by themselves in a toilet or the like.

[0004] As a toilet paper holder that can cut toilet paper with one hand, there has been proposed a toilet paper holder including a U-shaped holder body whose back side is attached to a wall surface, an arm for holding a roll of toilet paper under the holder body, a cover pivotally supported on the back side of the holder body for opening and closing its opening, a paper guide for guiding the toilet paper fed out from the arm upward inside the holder body to the front side, and a cutter located at the tip of the holder body (see, for example, Claim 1 of Patent Document 2).

[0005] According to the aforementioned toilet paper holder, toilet paper can be easily and reliably cut with one hand without using both hands, the end of the toilet paper is easy to grasp, and the toilet paper can be easily pulled out, thus simplifying the toilet paper replacement process (see, for example, paragraph

[0014] of Patent Document 2).

[0006] However, when using the aforementioned toilet paper holder in place of an existing toilet paper holder mounted on the wall of a toilet or similar, it is necessary to remove the existing toilet paper holder before installing the aforementioned toilet paper holder. This requires not only work to remove the existing toilet paper holder, work to install the aforementioned toilet paper holder, and various expenses for such work, but also the fact that the removed existing toilet paper holder will no longer be used and will therefore be subject to disposal even though it is still in usable condition.

[0015] In addition, according to the simple paper cutter of the present invention, since the toilet paper can be cut with one hand just by attaching it to an existing toilet paper holder, there is no need for the removal work of the existing toilet paper holder or the installation work of a toilet paper holder that can be cut with one hand, and various expenses required for these works can be reduced.

[0016] Therefore, the simple paper cutter of the present invention can be attached to and used with a toilet paper holder already installed in toilets of various facilities as well as ordinary households. In addition, a toilet paper holder equipped with the simple paper cutter of the present invention in advance can also be used.

[0017] Hereinafter, the simple paper cutter of the present invention will be described based on the drawings, but the present invention is not limited only to the embodiments described in such drawings.

[0018] FIG. 1 is a schematic explanatory view showing an embodiment of the simple paper cutter of the present invention. FIG. 2 is a schematic perspective view showing an embodiment of a toilet paper holder when the simple paper cutter for a toilet paper holder of the present invention is attached to the toilet paper holder in a form where the toilet paper is cut with one hand while holding the upper lid of the toilet paper holder with the other hand.

[0019] The simple paper cutter 1 of the present invention includes an upper lid holding portion 2 for holding the upper lid 12 of the toilet paper holder 11, a cutting blade 3 for cutting the toilet paper 13, and a connecting member 4 for connecting the upper lid holding portion 2 and the cutting blade 3.

[0020] The toilet paper holder 11 may be any one that can attach the simple paper cutter 1 of the present invention, and the present invention is not limited by the form of the toilet paper holder 11. The upper lid 12 of the toilet paper holder 11 is also referred to as a flap and is installed so as to cover the upper surface of the toilet paper 13 installed in the toilet paper holder 11.

[0021] The upper lid holding portion 2 of the simple paper cutter 1 has a recess 2a for inserting the end portion of the upper lid 12 of the toilet paper holder 11. The upper lid 12 of the toilet paper holder 11 is held by the recess 2a of the upper lid holding portion 2.

[0022] The gap B between the inner walls of the recess 2a of the upper lid holding portion 2 is not particularly limited as long as the upper lid 12 of the toilet paper holder 11 can be inserted. The gap B of the recess 2a of the upper lid holding portion 2 cannot be determined unconditionally because the thickness of the upper lid 12 of the toilet paper holder 11 varies depending on the type of the toilet paper holder 11, but from the viewpoint of enabling the upper lids 12 of various toilet paper holders 11 to be easily inserted into the recess 2a of the upper lid holding portion 2, it is preferably about 10 to 20 mm.

[0023] The depth D of the recess 2a of the upper lid holding portion 2 is not particularly limited as long as the upper lid 12 of the toilet paper holder 11 can be inserted and held. From the viewpoint of enabling the upper lids 12 of various toilet paper holders 11 to be held in the recess 2a, the depth D of the recess 2a of the upper lid holding portion 2 is preferably about 15 to 40 mm.

[0024] The length L of the top lid holding part 2 cannot be determined in general, as it varies depending on the width of the top lid 12 of the toilet paper holder 11. The width of the top lid 12 of the toilet paper holder 11 is generally adjusted considering the width of the toilet paper 13. The width of the toilet paper 13 is specified in JIS P4501-1993 as 114±2mm. Therefore, it is preferable that the length L of the top lid holding part 2 be greater than or equal to the width of the top lid 12 of the toilet paper holder 11, and is preferably about 120 to 130mm from the viewpoint of allowing the top lid 12 of the toilet paper holder 11, which is inserted into the recess 2a of the top lid holding part 2, to be easily fixed within the recess 2a.

[0025] The top lid 12 of the toilet paper holder 11 is inserted into the recess 2a of the top lid holding part 2 and then fixed within the recess 2a of the top lid holding part 2.

[0026] Methods for fixing the top lid 12 of the toilet paper holder 11 within the recess 2a of the top lid holding part 2 include, for example, as shown in Figure 3, inserting a tapered wedge 5 into the gap between the top lid 12 of the toilet paper holder 11 and the inner surface of the recess 2a of the top lid holding part 2 from the thinner side of the wedge 5 to fix the top lid 12 of the toilet paper holder 11 in the recess 2a of the top lid holding part 2; forming screw grooves (not shown) on one or both sides 2b of the top lid holding part 2 and screwing a screw 6 into the screw grooves and tightening it to fix the top lid 12 of the toilet paper holder 11 within the recess 2a of the top lid holding part 2; and fixing the contact surface between the top lid 12 of the toilet paper holder 11 and the inner surface of the recess 2a of the top lid holding part 2 with adhesive means such as adhesive or double-sided adhesive tape. However, the present invention is not limited to these examples.

[0027] Figure 3 is a schematic diagram illustrating one embodiment in which the upper lid 12 of the toilet paper holder 11 is fixed by a wedge 5 or a screw 6 within the recess 2a of the upper lid holding portion 2 of the simple paper cutting tool 1 of the present invention.

[0028] The cross-sectional shape of the top lid holder 2 is the shape of the Japanese character "コ" (ko) in the embodiments shown in Figures 1 to 3, as it has a recess 2a. However, the present invention is not limited by the cross-sectional shape of the top lid holder 2. The inner wall of the recess 2a of the top lid holder 2 may have a taper, and the bottom of the recess 2a of the top lid holder 2 may have an arc.

[0029] The top lid holder 2 can be manufactured using a resin such as ABS resin, AS resin, polycarbonate, polyacetal, acrylic resin, or polyester by a molding method such as injection molding.

[0030] As shown in Figure 1, the top lid holder 2 has a friction surface 2c with the toilet paper 13 for stopping the rotation of the toilet paper 13 when cutting the toilet paper 13. The friction surface 2c with the toilet paper 13 is the surface that comes into contact with the toilet paper 13, and more specifically, it is the surface on the side wall of the top lid holder 2 that comes into contact with the toilet paper 13. The friction surface 2c may be a smooth surface, or it may have irregularities, protrusions, etc., formed on it, within a range that does not impair the function of the simple paper cutting tool 1 of the present invention, in order to make it easier to suppress the rotation of the toilet paper 13.

[0031] The top lid holder 2 is connected to the cutting blade 3 for cutting the toilet paper 13 via a connecting member 4. The connecting member 4 is a member for connecting the top lid holder 2 and the cutting blade 3. The top lid holder 2 is attached to one end of the connecting member 4, and the cutting blade 3 is attached to the other end of the connecting member 4.

[0032] When using the toilet paper holder 11, stress is applied to the connecting member 4 when the toilet paper 13 is pulled and pushed downward to cut it with the cutting blade 3. Therefore, it is preferable that the connecting member 4 be made of a material with high mechanical strength. Examples of materials that can be used for the connecting member 4 include metals such as stainless steel, iron, copper, and brass, and resins such as ABS resin, AS resin, polycarbonate, polyacetal, acrylic resin, and polyester. However, the present invention is not limited to these examples.

[0033] The shape of the connecting member 4 is not particularly limited, but it is preferably flat in shape considering the ease of attaching the upper lid holding part 2 and the cutting blade 3 to the connecting member 4, and the mechanical strength of the connecting member 4. In the embodiments shown in Figures 1 and 2, a flat connecting member 4 is used.

[0034] In the embodiments shown in Figures 1 and 2, the connecting member 4 is provided on the right side (not shown) of the top lid holder 2 as viewed from the drawing, but it may also be provided on the left side (not shown) of the top lid holder 2, or on both the right and left sides of the top lid holder 2. From the viewpoint of enabling easy attachment of the toilet paper 13 below the top lid holder 2 within the toilet paper holder 11, it is preferable that the connecting member 4 is provided on either the right or left side of the top lid holder 2.

[0035] Between the upper lid holder 2 and the cutting blade 3, which are connected by a connecting member 4, a passage 7 for the toilet paper 13 is formed to allow the toilet paper 13 to pass through. In the embodiment shown in Figure 1, the distance between the front lower end 2d of the upper lid holder 2 and the tip 3a of the cutting blade 3 is preferably about 30 to 60 mm, from the viewpoint of enabling the toilet paper 13 installed in the toilet paper holder 11 to be easily connected to the cutting blade 3 via the sliding surface 2c of the upper lid holder 2 and the passage 7, and also so that the toilet paper 13 is fixed to the sliding surface 2c of the upper lid holder 2 when the toilet paper 13 is pushed down to be cut by the cutting blade 3.

[0036] The cutting blade 3 is attached to the connecting member 4 so that the toilet paper 13 that has passed through the passage 7 between the upper lid holding part 2 and the cutting blade 3 is cut by the cutting blade 3. In order to allow the toilet paper 13 to be easily cut when the toilet paper 13 is pushed downward via the cutting blade 3, it is preferable that the cutting blade 3 is mounted so as to protrude in front of the simple paper cutter 1, and more preferably mounted horizontally in front of the simple paper cutter 1.

[0037] Preferably, the tip 3a of the cutting blade 3 has multiple sawtooth-shaped protrusions with sharp angles to easily cut the toilet paper 13. The number of protrusions provided on the tip 3a of the cutting blade 3 is not particularly limited and should be any number that can easily cut the toilet paper 13, for example, about 30 to 50.

[0038] The material constituting the projection of the cutting blade 3 is not particularly limited and can be any material that can easily cut toilet paper 13. Examples of materials that can constitute the tip 3a of the cutting blade 3 include resins such as silicone resin, olefin resins such as polypropylene, polyamide, polyimide, ABS resin, AS resin, polycarbonate, polyacetal, acrylic resin, and polyester; rubbers such as silicone rubber, butadiene rubber, and styrene-butadiene rubber; elastomers such as polyester elastomer and polyethylene elastomer; and metals such as stainless steel, iron, copper, and brass. However, the present invention is not limited to these examples. Among these materials, resins, rubbers, and elastomers are preferred from the viewpoint of preventing injuries when fingers or other body parts come into contact with the tip 3a of the cutting blade 3.

[0039] The cutting blade 3 may be directly attached to the connecting member 4, or it may be attached to the connecting member 4 via a mounting base 8 for the cutting blade 3. In the embodiment shown in Figure 2, the cutting blade 3 is attached to a mounting base 8 made of, for example, resin, and the mounting base 8 is attached to the connecting member 4.

[0040] Methods for attaching the top lid holder 2 and the cutting blade 3 to the connecting member 4 include, for example, attaching the top lid holder 2 and the cutting blade 3 to the connecting member 4 using an adhesive or double-sided adhesive tape; attaching the top lid holder 2 and the cutting blade 3 to the connecting member 4 by screw fitting; providing protrusions on the side ends of the top lid holder 2 and the cutting blade 3 and providing grooves corresponding to the protrusions in the connecting member 4, inserting the protrusions into the grooves, and attaching the top lid holder 2 and the cutting blade 3 to the connecting member 4 by forced fitting; and using thermoplastic resin as the material constituting the top lid holder 2, the cutting blade 3, and the connecting member 4, and manufacturing a molded body in which the top lid holder 2, the cutting blade 3, and the connecting member 4 are integrated by injection molding or the like. However, the present invention is not limited to these examples.

[0041] The simple paper cutting device 1 of the present invention, configured as described above, can be attached to various existing toilet paper holders 11. However, the simple paper cutting device 1 of the present invention is not applicable to all toilet paper holders 11, and there may be cases where it cannot be applied depending on the shape of the toilet paper holder 11's lid 12.

[0042] The simple paper cutting tool 1 of the present invention can be suitably used with a toilet paper holder 11 that has a configuration in which the user holds down the top lid 12 of the toilet paper holder 11 with one hand while cutting the toilet paper 13 with the other hand.

[0043] The toilet paper holder 11 having the simple paper cutting tool 1 of the present invention has a configuration in which, when cutting toilet paper 13, the user holds down the top lid 12 of the toilet paper holder 11 with one hand while cutting the toilet paper 13 with the other hand. The simple paper cutting tool 1 of the present invention can be attached to the top lid 12 of the toilet paper holder 11 by inserting the top lid 12 of the toilet paper holder 11 into the recess 2a of the top lid holding part 2 of the simple paper cutting tool 1 of the present invention and fixing the top lid 12 within the recess 2a.

[0044] When a toilet paper holder 11 equipped with the simple paper cutting tool 1 of the present invention is used to pull out toilet paper 13 from the toilet paper holder 11 and cut the toilet paper 13 with the cutting blade 3 of the simple paper cutting tool 1, the toilet paper 13 is pulled downward. In this case, the pivot axis to which one end of the top lid 12 of the toilet paper holder 11 is attached becomes the fulcrum, the friction surface 2c between the top lid holding part 2 of the simple paper cutting tool 1 and the toilet paper 13 becomes the point of force application, and the cutting blade 3 of the simple paper cutting tool 1 becomes the point of application. Due to the principle of leverage, when the toilet paper 13 is pulled downward with one hand, the toilet paper 13 is pressed against the friction surface 2c of the top lid holding part 2 of the simple paper cutting tool 1, so that the sliding of the toilet paper 13 on the friction surface 2c of the top lid holding part 2 of the simple paper cutting tool 1 is suppressed, and the stress when the toilet paper 13 is pulled downward with one hand makes it easy to cut the toilet paper 13.

[0045] The simple paper cutting device 1 of the present invention can be attached to an existing toilet paper holder 11 without having to remove the existing toilet paper holder 11, allowing a person with a disability in one hand to easily cut toilet paper with the other hand, thus enabling effective use of the existing toilet paper holder.

[0046] Therefore, the simple paper cutting device 1 of the present invention is expected to meet the recent demands for barrier-free design, as it allows users to easily cut toilet paper with one hand simply by attaching it to toilet paper holders already installed in public facilities such as facilities for the disabled, public restrooms, train station restrooms, community centers, department stores, movie theaters, and home restrooms.
