Retrofit roll cutter

Abstract

Conventional retrofit roll cutters are attached to the existing roll holder, but require screws for installation. However, the retrofit roll cutter of the present invention secures the top plate (2) by inserting the insertion part (1) between the lid (9a) and the mounting part (9b) of the existing roll holder. [Solution] The retrofit roll cutter of the present invention has an insertion part (1) and a top plate (2) that intersect at a right angle, and when the insertion part (1) is inserted between the lid (9a) and the mounting part (9b) of an existing holder (9), the top plate (2) can be fixed, the blade (2a) of the top plate (2) can cut the paper (8a), and a tongue-out part (8b) is also created.

Description

[Technical Field]

[0001] The present invention relates to a roll cutter that can be attached to an existing roll holder, allowing cutting with one hand and also allowing protruding of the tongue. [Background technology]

[0002] The retrofit roll cutter of Patent Document 1, Patent No. 07349045, as shown in Figure 11, is attached to an existing holder (9) that cannot be cut with one hand, so the existing holder (9) is not wasted. The retrofit roll cutter is made up of a hinge (7a), which is made up of an attachment part (7b) and a conventional top plate (7), and the attachment part (7b) is attached to the top of the existing holder (9), so cutting can be done with one hand and the tongue part (8b) can be protruded. Furthermore, Patent Document 2, JP 2012-71077 A, discloses a cut plate for a toilet paper holder that is attached to the lid. Furthermore, in Patent Document 3, Japanese Utility Model Application Laid-Open No. 62-24794, an attachment named "Roll Paper Holder" uses a hinge and a spring to connect the lifting plate and the swinging plate.

[0003] [Patent Document 1] Patent No. 07349045 [Patent Document 2] Patent Publication No. 2012-71077 [Patent Document 3] Jippan No. 62-24794 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0004] The attachment part of the conventional retrofit roll cutter in Patent Document 1 is attached to the top of the existing holder (9) as shown in Figure 11, so if the wall (10) is made of tiles or the like, it is attached with double-sided tape or adhesive, and if the wall (10) is made of wood, it is attached with screws or nails, etc. However, even attaching with double-sided tape or screws is troublesome for an amateur. Furthermore, in Patent Document 2, JP 2012-71077 A, the name of the "Cutting Plate for Toilet Paper Holder" is a cutting plate attached to a cover with double-sided adhesive tape. Therefore, the cutting plate gently points downward along the cover, and like the cover, the cutting plate surface is curved. Therefore, the protruding portion is only about 5 mm, and it is not designed to only pick up the paper. In other words, if it is 5 mm, fingers will touch other parts, which is unhygienic. Furthermore, the attachment named "Roll Paper Holder" in Patent Document 3, Japanese Utility Model Application Publication No. 62-24794, uses a hinge and a spring to connect the lifting plate and the swinging plate. Therefore, making the hinge and spring required extra work. Furthermore, it is not possible to stick out the tongue, which is an important feature because it is used to avoid touching unnecessary places with contaminated hands when entering the toilet.

[0005] Therefore, the retrofit roll cutter of the present invention is easy to install because it is fixed by inserting the insertion part (1) between the lid (9a) and the mounting part (9b) of the existing holder (9), and the difference between the position of the blade (2a) attached to the tip of the top plate (2) and the position of the tip of the lid (9a) determines the length of the tongue-out part (8b). [Means for solving the problem]

[0006] In order to achieve the above object, the post-attached roll cutter of the present invention is composed of a retracted, approximately L-shaped insertion portion (1) and a top plate (2), and the insertion portion (1) is narrower than the width of the top plate (2).

[0007] The insertion portion (1) is inserted between the hinge (9d) side of the lid (9a) of the existing holder (9) and the mounting portion (9b) to be fixed, and is therefore smaller than the width of the lid (9a).

[0008] The top plate (2) is installed directly above the existing holder (9) and is wider than the width of the lid (9a) of the existing holder (9). Furthermore, the top plate (2) is equipped with a jagged edge (2a) at the tip, and the distance between the edge (2a) and the tip (9a) of the lid (9a) at the tip of the lid (9a) is the length of the tongue (8b), and this length is 3 cm or more, thereby achieving the purpose. [Effects of the Invention]

[0009] The post-attached roll cutter of the present invention has the following effects. (i) The retrofit roll cutter can be easily installed by inserting the insert between the lid and the mounting part. (See paragraph 0023 for details) (b) The insertion part is V-shaped to make it easier to insert. (See paragraph 0033 for details) (c) Since it is an after-market attachment, it does not waste the existing roll holder. (See paragraph 0011 for details) (d) Paper can be cut with one hand. (See paragraph 0019 for details.) (e) The tongue can be pushed out, making it easier to grab the paper. (See paragraph 0017 for details.) (F) Since the child can stick out his tongue, do not touch any unnecessary parts. (See paragraph 0017 for details) (G) Items can be placed in the area surrounded by the edge of the tabletop. (See paragraph 0032 for details.) (H) Because it is an angle, the structure is simple. (See paragraph 0018 for details.) (i) If the top plate is made transparent, it will be easier to see the tongue-out state. (See paragraph 0034 for details.) (Ju) The hole at the end of the top plate makes it easy to see the tongue-out state. (See paragraph 0033 for details.) [Brief explanation of the drawings]

[0011] The retrofit roll cutter of the present invention is easy to install and has a protruding tongue (8a). First, it is installed on top of an existing holder (9) that cannot be cut with one hand, so the existing holder (9) is not wasted. The retrofit roll cutter is made of a retracted, approximately L-shaped angle, and is composed of an insertion part (1) and a top plate (2).

[0012] The existing holder (9) can easily cut the paper (8a) by placing a weight on the lid (9a) to apply weight, but it does not have a protruding part (8b). Therefore, without the protruding part (8b), the user had to lift the lid (9a) of the existing holder (9) and rotate the roll (8) to expose the paper (8a) [protruding part (8b)], but now it takes both hands to lift the lid (9a) and remove the paper (8a).

[0013] Also, touching the lid (9a) in the toilet is unhygienic. Therefore, the insertion part (1) is inserted between the hinge (9d) side of the lid (9a) of the existing holder (9) and the mounting part (9b) to attach it. Meanwhile, when the insertion part (1) is inserted into the top plate (2), it is fixed on top of the existing holder (9), and the paper (8a) of the roll (8) passes through the lid (9a) and is cut by the blade (2a) of the top plate (2). The area between the blade (2a) and the tip (9f) of the lid (9a) becomes the protruding part (8b). The protruding part (8b) is wound around the roll (8), and since it has just been pulled out and has not yet been touched by anyone's hands, it is hygienic.

[0014] On the other hand, when the insertion part (1) is inserted into the top plate (2), the top plate (2) sticks to the existing holder (9) and is fixed so that it does not move by the insertion part (1) and the top plate (2). However, if non-slip rubber is used under the top plate (2), it will not rattle.

[0015] The top plate (2) is equipped with a blade (2a) at its tip, which resembles a saw blade. If the blade (2a) of the top plate (2) is tilted slightly, part of the paper (8a) will come into strong contact with the blade (2a) and cut it. However, if the blade (2a) is not jagged, it will slide even when tilted to the side, and no force will be applied to one part, so the jagged surface of the blade (2a) also serves as a non-slip surface.

[0016] To use it, first take the tongue-out part (8b) in your hand (8c), pull it down to rotate the roll (8) and take the appropriate length, then turn the paper (8a) towards you, lift it up, and bring it to the edge of the wall (10), and tilt the paper (8a) to the left, and the rightmost part of the paper (8a) that hits the blade (2a) of the top plate (2) will tear off.

[0017] The remaining paper (8a) hangs down, forming the protruding part (8b). Therefore, the difference in position between the blade (2a) of the top plate (2) and the tip of the lid (9a) is the length of the protruding part (8b). In other words, the shape of the lid (9a) follows the outline of the roll (8), while the top plate (2) is part of an angle, and there is an opening between the blade (2a) at the tip of the top plate (2) and the tip (9f) of the lid (9a), which forms the protruding part (8b), and the length of the protruding part (8b) is more than 3 cm. The protruding part (8b) prevents touching unnecessary parts, making it hygienic, and the protruding part (8b) is long enough to be easily picked up. Furthermore, the protruding part (8b) is hygienic because it never comes into contact with human hands (8c). Especially in the toilet, since your hands are the ones that handle the waste, you have to acknowledge that your hands are unsanitary, and considering that the same is true for those who have used the toilet before, it is hygienic to avoid touching other people's hands. Example 1

[0018] The post-attaching roll cutter of the present invention will be described with reference to the drawings. The solid line in the perspective view of Figure 1 represents the add-on roll cutter, and the dotted line represents the existing holder (9), paper (8a), and hand (8c). The add-on roll cutter is roughly L-shaped when turned upside down, and its vertical insertion part (1) is inserted between the mounting part (9b) and the lid (9a) of the existing holder (9), so it is the same width as the lid (9a), 120 mm or less, and its thickness is 2 mm, with an insertion length of 90 mm or more.

[0019] When the insert (1) of the top plate (2) is inserted vertically, it is horizontal and at least 170 mm wide, the same width as the existing holder (9). The length from the corner of the top plate (2) to the blade (2a) is 150 mm. The dotted line shows the 114 mm wide roll (8) of paper (8a) being cut or torn in order from the left end with the hand (8c) tilted to the right, and all of this can be done with one hand.

[0020] Figure 2 is a perspective view of the retrofit roll cutter of the present invention. The width of the top plate (2) is 170 mm, which is larger than the width of the existing holder (9). The width of the insertion portion (1) is approximately 120 mm, the same as the lid (9a) of the existing holder (9). Therefore, there is a 50 mm difference in the width of the top plate (2) and the insertion portion (1), with the insertion portion (1) being 25 mm shorter. This is because when the paper (8a) remains as a protruding portion (8b), a length of more than 3 cm causes wobble on the left and right, so a 25 mm margin is provided on both sides.

[0021] Figure 3 shows a cross-sectional view of the paper pulled out at 2 o'clock, as indicated by the hands of a clock. The protruding part (8b) of the roll (8) is taken in the hand, an appropriate length is pulled downward, and the paper (8a) is pulled toward the user. The protruding part (8b) is the paper (8a), and the part below the cut paper (8a) is conveniently called the protruding part (8b). However, when the protruding part (8b) is taken in the hand (8c) and the roll (8) is pulled out, the name of the protruding part (8b) changes from the protruding part (8b) to the paper (8a).

[0022] It would be easy to tilt the paper (8a) to the left and cut it with the tip (9f) of the lid (9a), but if you cut the paper (8a) with the tip (9f) of the lid (9a), there will be no protruding tongue (8b). Therefore, you need to lift the lid (9a), grab the edge of the paper (8a), and pull out the paper (8a). Since the subsequent operations are cumbersome, I pulled it straight down so that it would not get cut by tilting it left or right, then tilted it up at an appropriate length and decided where to cut it.

[0023] Figure 4 is a side cross-sectional view of the same state as Figure 1. The mounting part (9b) is a part of the existing holder (9), and only the part that is fixed to the wall (10) with screws or nails is called the mounting part (9b). The mounting part (9b) and the lid (9a) have the same width, and the insertion part (1) is inserted between the mounting part (9b) and the lid (9a) to fix them in place.

[0024] The top plate (2) is fixed on top of the existing holder (9), and the paper (8a) is pulled in your direction, between 1 and 2 o'clock on a clock, and then pulled further towards the wall (10). If you bring it to 10 o'clock on a clock and tilt the paper (8a) to the left, the right side of the paper (8a) will be pulled. As the pulling force is concentrated on the right end of the pulled paper (8a), when the paper (8a) can no longer withstand the force, the cut moves from the right end to the left, and the paper (8a) is cut. The remaining paper (8a) hangs down, forming the dotted tongue (8b).

[0025] The tongue sticking out (8b) is an important part, and touching unnecessary parts in the toilet is not hygienic, so the tongue sticking out (8b) is there. Since the tongue sticking out (8b) part is used, the paper (8a) from the tongue sticking out (8b) part that has been removed is flushed down the toilet after using the toilet. And, since the tongue sticking out (8b) part that has just been created has not been touched by any human hands, it is hygienic. Example 2

[0026] Figure 5 is a side cross-sectional view of the top plate (2) with a hinge (2b) attached. To smoothly cut the paper (8a), the top plate (2) needs to be a certain length, but if it protrudes too much as it is, it could injure someone's knees. Therefore, a hinge (2b) is attached to the long top plate (2), and although the blade (2a) normally hangs down, the paper (8a) is pulled down, and once the appropriate length is obtained, it is then pulled up, as shown in Figure 5.

[0027] If the paper (8a) is tilted to the right, the pulling force is concentrated on the left end of the paper (8a), making it impossible for the paper (8a) to maintain its shape, and the paper (8a) starts to cut from the left end and cuts all the way to the end.Then, the dotted protruding part (8b) of the paper (8a) remains, and the hinge (2b) of the paper (8a) moves downwards on the blade (2a), causing the protruding part (8b) to fold and fall down, as shown by the dotted line in Figure 5.After cutting, the weight of the blade (2a) causes it to drop down, becoming compact, and the blade (2a) is facing downwards, making it safe. Example 3

[0028] Figure 6 is a cross-sectional view of the top plate (2) with a hook (2e) attached. When replacing the roll (8), if you try to lift the top plate (2) to remove the insertion part (1) from the existing holder (9), it will tilt and may not come out smoothly, so the hook (2e) was attached. By lifting the hook (2e) and removing the retrofit roll cutter, the existing holder (9) will remain and the roll (8) can be replaced, so it is used when the roll (8) has been used up.

[0029] Also, if the length of the insertion portion (1) is increased from approximately 90 mm to 300 mm, the insertion portion (1) can be lifted approximately 200 mm, the lid (9a) of the existing holder (9) can be opened, the top plate (2) can be lowered and supported by the lid (9a). Then, the roll (8) can be replaced, the lid (9a) can be replaced, and the top plate (2) can be lowered and placed on top of the existing holder (9). This allows for easy replacement of the roll (8) without having to completely remove the insertion portion (1). Example 4

[0030] Figure 7 is a side view of the cover (2f) attached to the top plate (2). The cover (2f) of the top plate (2) is designed to enclose the 170 mm width of the existing holder (9), and is effective when the insertion part (1) alone is unstable. The top plate (2) is equipped with a hook (2e) and a hinge (2b), and a stopper is attached to the hinge (2b) to align it with the top plate (2) as shown by the dotted line when it is raised all the way up.

[0031] Figure 8 is a perspective view of the top plate (2) with the cover (2f) attached. This perspective view shows only the retrofit roll cutter, excluding the existing holder (9). The view clearly shows the relative positions of the hook (2e), top plate (2), hinge (2b), blade (2a), and insertion part (1). Example 5

[0032] Figure 9 is a perspective view of a tabletop (2) with a lip (2g) attached. The tabletop (2) has a cover (2f), but since it is just a lip (2g), it can be attached to any tabletop (2). Wallets, driver's licenses, and other items that may fall out of your trouser pockets can be placed on the tabletop (2) in front of you, making them less likely to be forgotten when you leave the toilet. It can also be used as a place to store a spare roll (8).

[0033] Figure 10 shows that inserting the insertion part (1) between the hinge (9d) of the lid (9a) of the existing holder (9) and the mounting part (9b) can sometimes be difficult due to the snag. In such cases, the tip can be sharpened to create an approximately V-shaped part (1a) for insertion. Therefore, it is easier to insert the insertion part by slightly chamfering the surface of the approximately V-shaped part (1a) of the insertion part (1). Also, a hole (2c) is drilled at the end of the top plate (2), and the protruding part (8b) can be seen through this hole (2c). Therefore, the hole (2c) does not have to be round; a square or rectangular shape makes it easier to see the protruding part (8b). However, if the retrofit roll cutter is made of transparent plastic, the protruding part (8b) can be seen more easily. Example 6

[0034] A detailed explanation of terms and symbols is provided. The retrofit roll cutter functions just like the conventional roll cutter, but by attaching a separate part, it solves the minor problems.The retrofit roll cutter simply inserts between the lid (9a) of the existing holder (9) and the mounting part (9b) to easily protrude the tongue (8b), which contributes to toilet hygiene. Reference numerals 1 and 2 are parts of the present invention. The insertion part (1) is a part of the retrofit roll cutter, and is inserted into the mounting part (9b) of the existing holder (9) and the hinge (9d) side of the lid (9a) to prevent the top plate (2) from moving. The V-shaped portion (1a) is attached with rounded corners to facilitate smooth insertion between the hinge (9d) side of the lid (9a) of the existing holder (9) and the mounting portion (9b). In addition, the surface of the V-shaped portion (1a) has been chamfered to make insertion even easier. The top plate (2) is placed on top of the existing holder (9), and the blade (2a) of the top plate (2) cuts the paper (8a) and adjusts the length of the tongue-out portion (8b). Furthermore, if the top plate (2) is made of transparent plastic, the tongue-out portion (8b) can be easily seen. Also, if a hole (2c) is drilled at the end of the top plate (2), the tongue-out portion (8b) below can be seen through the hole (2c), so drilling the hole (2c) eliminates the need for a transparent plate. The blade (2a) has a serrated edge (2a) to cut the paper (8a), and the serrated edge (2a) is attached to prevent the paper (8a) from sliding sideways, so it is unclear whether it is appropriate to say that it cuts the paper (8a) or that it tears it apart. If the length of the top plate (2) is too long, the protruding blade (2a) will get in the way and cause injury in a narrow space. Therefore, the hinge (2b) is attached and the top plate (2) is divided into two parts to adjust the length, so that when not in use it will drop down to become small and not get in the way. The hole (2c) is made at the end of the top plate (2), just before the blade (2a), and the state of the tongue-out part (8b) can be seen through the hole (2c). The hole (2c) does not have to be round; a square or rectangular shape makes it easier to check the tongue-out part (8b).

[0035] The hook (2e) is a handle for holding the entire post-attached roll cutter, and the index finger through the little finger are hooked onto it, the insertion part (1) is pulled out, the lid (9a) is opened, and the roll (8) is replaced. The cover (2f) reinforces the existing holder (9) by enclosing it in its entirety when the insertion part (1) alone moves, and also improves its appearance. The edge (2g) is attached to the top plate (2), which is a flat area of ​​about 300 square centimeters, and since it would be a waste not to use the top plate (2), the edge (2g) is made a little higher so that things do not fall off the top plate (2), and it becomes a place to put things on the top plate (2). The things that can be put on it can be various, such as a wallet in a trouser pocket, a spare roll (8), or a vase.

[0036] (Reference numerals 7 to 7c) are the rear roll cutters invented previously, and are the parts shown in Figure 11. In the conventional tabletop (7), the length of the tongue-out (8b) is determined by the legs (7c) provided thereon. The hinge (7a) is used when replacing the roll (8), and the hinge (7a) is used when attaching the conventional top plate (7) to the wall (10) to open it, opening the lid (9a), and replacing the roll (8). The mounting part (7b) is not necessary in this invention, but previously it was attached using screws, double-sided tape, etc. However, amateurs had to ask a professional to do even the work of driving in the screws, so by changing the mounting part (7b) to the insertion part (1) of the present invention, anyone can use it immediately. The height of the leg (7c) is equal to the length of the tongue (8b) of the paper (8a). (Codes 8-8b) are partial names of the role (8). The roll (8) is a rolled mass of paper (8a). The paper (8a) is obtained by peeling the paper (8a) from the roll (8). The tongue-out portion (8b) is a portion that is cut from the blade (2a) of the top plate (2) to use the paper (8a), and the remaining paper (8a) makes it easy to pull out the next paper (8a).

[0037] (Reference numerals 9 to 9d) are the part names of the existing holder (9). The existing holder (9) is the same as the one installed in most toilets, but it can also be used with older existing holders. The lid (9a) is attached to the existing holder (9) and opens upward using a hinge (9d), and originally the tip of the lid (9a) was used to cut the paper (8a). The mounting part (9b) has a hole for attaching the existing holder (9) to the wall (10), and the mounting part (9b) is thin, about 15 mm thick, and the hinge (9d) of the lid (9a) is attached to its end, and the insertion part (1) of the retrofit roll cutter is inserted between the hinge (9d) and the mounting part (9b). The shaft (9c) is a mandrel for supporting the roll (8). Hinge (9d) is a part of the lid (9a) and is drawn to represent the part of the lid (9a) that is closer to the wall (10), and this hinge (9d) is used when replacing the roll (8). The lid tip (9f) is provided on the lid (9a), and the lid tip (9f) has a blade because it was used to cut the existing roll (8). The wall (10) is a wall (10) for attaching the existing holder (9). [Industrial Applicability]

[0038] This add-on roll cutter is not only useful in restrooms, but also in laboratories and other places where hygiene is a major concern, making it more hygienic than tissue paper that is left lying around. In particular, when cutting paper towels with one hand in a home kitchen, some paper towels have slits, but there is nothing to hold them against, making it impossible to do so. By cutting with the top plate (2) of the present invention, you can cut the paper towel with one hand while still holding a pot or other object, and then use the paper towel to wipe the pot.
