Description

[Technical Field]

[0001] The present invention relates to a toilet paper cutter for cutting toilet paper attached to a toilet paper holder with one hand, and to a toilet paper holder. [Background technology]

[0002] A typical toilet paper holder has a support shaft that rotatably supports toilet paper, and a pressure plate that is arranged above the toilet paper and has a cutter.

[0003] The toilet paper holder allows you to (1) pull out the appropriate amount of toilet paper with one hand, (2) hold down the pressure plate with the other hand to stop the toilet paper from rotating and prevent any more toilet paper from being pulled out, and (3) press the pulled-out part of the toilet paper against the cutter on the pressure plate to cut the toilet paper, thereby cutting the amount of toilet paper you want to use.

[0004] However, as mentioned above, toilet paper holders are designed to be used with both hands, which can make them difficult to use for people with physical disabilities, for example.

[0005] As a technology to solve such problems, for example, Patent Document 1 discloses a toilet paper holder technology in which an approximately L-shaped part consisting of a cover and a cutting blade is attached to the outside of the tip of the top lid via a hinged part, allowing the toilet paper to be cut with one hand. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-146948 Summary of the Invention [Problem to be solved by the invention]

[0007] However, since the above-mentioned technology is a toilet paper holder technology, it cannot be used unless it is replaced with an existing toilet paper holder.

[0008] Furthermore, when using the toilet paper holder relating to the aforementioned technology, it is claimed that the gripping edge will be automatically formed the next time it is used (see paragraph 0022 of Patent Document 1, etc.), but due to its structure, the length of the gripping edge is fixed at the length from the pull-out opening to the tip of the cutting blade, which is too short for people with physical disabilities and makes it difficult to grip.

[0009] The present invention was made in consideration of the above-mentioned problems of the prior art. The main object of the present invention is to provide a toilet paper cutter that can be used without replacing an existing toilet paper holder, has an adjustable grip length, and can be used to cut toilet paper attached to a toilet paper holder with one hand.

[0010] Another object of the present invention is to provide a toilet paper holder that allows the user to cut the toilet paper with one hand.

[0011] According to a first aspect of the present invention, there is provided a cutter for cutting toilet paper attached to a toilet paper holder, the cutter comprising a cutter section which is a blade for cutting the toilet paper, a trigger section which is connected to the cutter section and is arranged on a passageway through which the toilet paper passes when pulled out, a shaft section which is an axis for rotating the cutter section and the trigger section so that when the trigger section is not pressed, the cutter section is in a first position where it does not engage with the toilet paper, and when the trigger section is pressed against the toilet paper, the cutter section is in a second position where it engages with the toilet paper, and an attachment section which can be attached to a wall surface to which the toilet paper holder is attached, and can be configured to be arranged at any distance from the toilet paper holder.

[0012] According to the above configuration, when the trigger is pressed by the toilet paper, the cutter moves to the second position and cuts the toilet paper, so the toilet paper attached to the toilet paper holder can be cut with one hand. Also, since the cutter according to the present invention is a device independent of the toilet paper holder, it can be used without replacing the existing toilet paper holder, and the length of the grip can be adjusted by adjusting the installation position of the cutter according to the present invention (the distance from the toilet paper holder).

[0013] Furthermore, the cutter according to the second aspect of the present invention can be configured to be attached below the toilet paper holder by the attachment part. With this configuration, the toilet paper can be used without being pulled above the toilet paper holder, making it easy to use even for people who have difficulty lifting their arms high.

[0014] According to the third aspect of the present invention, the mounting part can be configured to be detachably mounted on the wall on which the toilet paper holder is mounted. This configuration makes it easier to adjust the mounting position of the cutter and the length of the grip.

[0015] Furthermore, according to a fourth aspect of the present invention, there is provided a cutting device comprising: one The cutter unit may be configured to include a cover portion that covers the cutter unit when moved to the position.

[0016] Furthermore, a cutter according to a fifth aspect of the present invention can be configured to include a first stopper portion that limits rotational movement of the trigger portion in the same direction as the direction from the first position to the second position, so that the trigger portion and the toilet paper engage at a substantially right angle at the second position. cutter The angle at which the part engages with the toilet paper can be fixed at a substantially right angle, which makes it easy to cut the toilet paper, so that the toilet paper can be cut more easily and reliably with one hand.

[0017] Furthermore, a cutting device according to a sixth aspect of the present invention can be configured to include a second stopper that limits rotational movement of the cutter unit in the first position in the same direction as the direction from the second position toward the first position. This configuration can prevent fingers from being pinched between the cutter unit and the cover unit, thereby improving the safety of the cutting device.

[0018] In addition, according to the seventh aspect of the present invention, the toilet paper holder can be configured to include a cutter portion which is a blade that cuts the toilet paper, a trigger portion which is connected to the cutter portion and is arranged on a passage path through which the toilet paper passes when pulled out, and an axis portion which is an axis for rotating and moving the cutter portion and the trigger portion so that when the trigger portion is not pressed, the cutter portion is in a first position where it does not engage with the toilet paper, and when the trigger portion is pressed against the toilet paper, the cutter portion is in a second position where it engages with the toilet paper.

[0020] Embodiments of the present invention will be described below with reference to the drawings. However, the embodiments described below are merely examples for embodying the technical concept of the present invention, and the present invention is not limited to these. Furthermore, this specification in no way specifies the components set forth in the claims as components of the embodiments. The dimensions, materials, shapes, and relative positions of components described in the embodiments are not intended to limit the scope of the present invention, and are merely illustrative unless otherwise specified. The size and relative positions of components shown in the drawings may be exaggerated for clarity. Furthermore, in the following description, the same names and symbols indicate identical or similar components, and detailed descriptions will be omitted as appropriate. Furthermore, each element constituting the present invention may be configured with the same component, so that multiple elements are served by a single component. Conversely, the function of a single component may be shared among multiple components. Furthermore, the functions or processing of each element constituting the present invention may be realized, to the extent possible, by artificial intelligence (AI). [Cutter 1]

[0021] A cutter 1 according to one embodiment of the present invention will be described with reference to FIGS.

[0022] The cutter 1 is a device for cutting toilet paper attached to a toilet paper holder TH, and as shown in Figures 1 to 3, is mainly composed of a rotating part 11, a base part 12 (which corresponds to an example of the "attachment part" in the claims), and a cover part 13. Each part will be explained below.

[0023] In the following description, the roll-shaped portion of the toilet paper TP is referred to as the roll portion TP1, and the sheet-shaped portion unwound from the roll portion TP1 is referred to as the sheet portion TP2. The path along which the sheet portion TP2 passes when unwound is referred to as the passing path TK. [Rotating part 11] <Configuration of Rotating Part 11>

[0024] 4, the rotating part 11 is a member made up of a cutter part 111, a trigger part 112, a shaft part 113, and a stopper part 114 (which correspond to examples of a "first stopper part" and a "second stopper part" in the claims), and the cutter part 111, the shaft part 113, and the stopper part 114 are connected to the trigger part 112. As a result, the entire rotating part 11 rotates based on the shaft part 113.

[0025] With this configuration, when the trigger portion 112 is pressed, the rotating portion 11 rotates around the shaft portion 113, and the cutter portion 111 cuts the sheet portion TP2. <Steps until the rotating part 11 cuts the sheet part TP2>

[0026] 5, the rotating unit 11 cuts the sheet portion TP2 mainly through steps ST101 during normal operation, ST102 during cutting, and ST103 immediately after cutting. Each step will be described below. 《Normal ST101》

[0027] Normal time ST101 is a step when a certain time has elapsed since external force was no longer applied to the rotating part 11, that is, when a certain time has elapsed since immediately after disconnection ST103.

[0028] In this step, the rotating part 11 is stationary at a position (first position) where the cutter part 111 does not engage with the sheet part TP2, as shown in FIG.

[0029] As a result, the cutter unit 111 is 3 This prevents a person from accidentally touching the cutter portion 111 and getting injured, thereby improving the safety of the cutter 1.

[0030] Furthermore, when attempting to rotate the rotating part 11 clockwise in the figure in the normal state ST101, the stopper part 114 engages with the base part 12, restricting the rotational movement of the rotating part 11. If the cutter 1 does not have the stopper part 114, let us suppose that the cutter part 111 in the normal state ST101 is touched with a finger and pushed in so as to rotate clockwise in the figure. In this case, the finger may come into contact with the cutter part 111 and the cover part 1 3 If a finger is caught between the cutter part 111 and the cutter, when an attempt is made to pull out the finger, the cutter part 111 may bite further into the finger. The stopper part 114 can prevent such an accident and can improve the safety of the cutter 1. 《ST102 when cutting》

[0031] Cutting step ST102 is a step in which the rotating part 11 cuts the sheet part TP2. This step will be described based on the operation of the cutter 1 by the user.

[0032] First, the user pulls out the sheet portion TP2 according to the amount he or she wants to use.

[0033] Next, the user presses the pulled-out sheet part TP2 against the trigger part 112 and presses the trigger part 112. This applies a force to the trigger part 112 as indicated by the arrow in FIG. 6, causing the cutter part 111 to rotate as shown in FIG. 7. Eventually, as shown in FIG. 8, the sheet part TP2 and the cutter part 111 engage (contact) with each other, and the blade of the cutter part 111 bites into the sheet part TP2 (the blade is bitten). At this time, tension is applied to the sheet part TP2 between the cutter part 111 and the roll part TP1. At this time, the stopper part 114 engages with the base part 12, restricting the rotational movement of the rotating part 11 so that the rotating part 11 does not rotate further counterclockwise in the figure.

[0034] Thereafter, when the user applies further force in the direction of pressing the pulled-out sheet part TP2 against the trigger part 112, the sheet part TP2 is cut by the cutter part 111 at the contact position between the sheet part TP2 and the cutter part 111 in Fig. 8. At this time, as described above, since the rotational movement of the rotating part 11 is limited, even if the user applies further force, Cutter part 111 The angle at which the hook engages with the toilet paper is fixed at a substantially right angle, which makes it easy to cut the toilet paper, and allows you to cut the toilet paper more easily and reliably with one hand.

[0035] In short, the user's action in cutting ST102 is simply to "press the pulled-out sheet part TP2 against the trigger part 112", which can be done with one hand. <<ST103 immediately after cutting>>

[0036] The step immediately after cutting ST103 is a step immediately after the step during cutting ST102 is completed (after the sheet part TP2 has been cut).

[0037] When the sheet portion TP2 is cut by the cutter portion 111, the tension applied to the sheet portion TP2 between the cutter portion 111 and the roll portion TP1 is released, and at the same time, the force (arrow in FIG. 6) applied to the trigger portion 112 is also eliminated. Then, the rotating portion 11 naturally returns to the first position due to its own weight, and returns to the normal state ST101 (first position, FIG. 6).

[0038] At this time, the portion of sheet TP2 that was under tension between roll TP1 and cutter 111 (see FIG. 8) hangs down and becomes a gripping area. In other words, when the cutter 1 according to the present invention cuts the toilet paper with one hand, a gripping area is naturally formed, which is convenient the next time the cutter 1 is used.

[0039] The length of the gripping margin to be formed is determined by the distance between the roll part TP1 and the cutter part 111. 2The length of the grip can be adjusted by adjusting the mounting position (details will be given later). <Other Aspects of Rotating Portion 11>

[0040] The dimensions, material, shape, positional relationship, etc. of the rotating part 11, cutter part 111, trigger part 112 and shaft part 113 are not limited to those described above, and can be changed as appropriate as long as the sheet part TP2 can be cut in the above-mentioned steps.

[0041] For example, in step ST103 immediately after cutting, the method by which the rotating part 11 returns to the normal state ST101 (first position, Figure 6) is not limited to a method using its own weight, but can be appropriately changed to a method using the elastic force of rubber, a spring, etc., or a combination of these.

[0042] In addition, stopper portion 114 can be realized by dividing it into multiple members, for example, it can be composed of two members, one corresponding to the "first stopper portion" in the claims and the other corresponding to the "second stopper portion." [Cover part 1 3 〕 <Cover part 1 3 Composition of

[0043] Cover part 1 3 1 to 3 and 6, is a plate-shaped member for covering the cutter section 111 which is normally in the state ST101 (first position). As shown in FIG. 8, when the cutter section 111 moves to a position (second position) where it engages with the sheet section TP2, the cutter section 11 moves to a position (second position) where it engages with the sheet section TP2. 3 The sheet portion TP2 can be cut off.

[0044] Cover part 1 3 By providing this, it is possible to prevent a person from accidentally touching the cutter portion 111 and getting injured, and the safety of the cutter 1 can be improved. <Cover part 1 3 Other aspects of

[0045] Cover part 13 The form of the cover part 1 is not particularly limited, and the dimensions, material, shape, positional relationship, etc. can be changed as appropriate. 3 does not necessarily have to be provided. [Base part 1 2 〕 <Base 1 2 Composition of

[0046] Base part 1 2 As shown in FIGS. 1 to 3 and 6 to 8, this is a member that serves as the base (foundation) of the cutter 1 and as a bearing for the shaft portion 113 of the rotating portion 11.

[0047] Base part 1 2 The cutter 1 is used by being attached to a wall on which a toilet paper holder TH is attached, for example.

[0048] In addition, the base part 1 2 When installing the base part 1 2 The length of the gripping edge formed can be easily adjusted by adjusting the distance between the roll portion TP1 and the toilet paper holder TH (more precisely, the distance between the roll portion TP1 and the cutter portion 111). In this respect, this technology is superior to conventional technologies (such as the technology disclosed in Patent Document 1) in which the length of the gripping edge cannot be easily adjusted.

[0049] In addition, the base part 1 2 If the toilet paper holder is attached below the toilet paper holder TH, the toilet paper can be used without having to be pulled above the toilet paper holder, making it easy to use even for people who have difficulty lifting their arms high. This point is also superior to the prior art (for example, the technology disclosed in Patent Document 1). <Base 1 2 Other aspects of

[0050] Base part 1 2 The form of the element is not particularly limited, and the dimensions, material, shape, positional relationship, etc. can be changed as appropriate.

[0051] In addition, the base part 12 The attachment method is not particularly limited, and examples include screws, nails, adhesives, magnets, double-sided tape, suction cups, hook-and-loop fasteners, etc. (each of which corresponds to an example of an "attachment portion" in the claims). Magnets, double-sided tape, hook-and-loop fasteners, etc. are particularly suitable because they are easy to attach and detach, and allow for easier adjustment of the grip length. Furthermore, the cutter 1 of the present invention is primarily targeted at physically disabled people (people who cannot use both hands), and by using the above-mentioned means, such people can easily attach the cutter 1 themselves. This is also an advantage over conventional technologies (such as the technology disclosed in Patent Document 1) that require the toilet paper holder itself to be replaced. [Effect of Cutter 1]

[0052] As described above, the cutter 1 according to one embodiment of the present invention can be used without replacing an existing toilet paper holder, and the length of the grip is adjustable, allowing the user to cut toilet paper attached to the toilet paper holder with one hand. [One-piece toilet paper holder with cutter 1 configuration]

[0053] It is also possible to apply the technical concept of the present invention to a general toilet paper holder to create an integrated toilet paper holder having the configuration of the cutter 1.

[0054] In this case, although replacement with an existing toilet paper holder is necessary, the toilet paper holder body can be designed to be used with cutter 1. In other words, the weight and friction coefficient of the pressure plate, the sharpness of cutter part 111, etc. can be taken into consideration, and the entire toilet paper holder can be adjusted at the design stage, making it possible to more easily and reliably cut toilet paper with one hand.

[0055] The length of the grip can be adjusted by configuring the toilet paper holder to have a function for adjusting the positional relationship between the toilet paper holder body and the cutter 1. [Explanation of symbols]
