Description

[Technical field]

[0001] The present invention relates to an add-on roll cutter that can be attached to an existing roll holder and allows cutting with one hand. [Background technology]

[0002] Conventional roll holders, such as that described in Patent Document 1, allow the user to cut off the toilet paper with one hand, and the holder is designed to make it easy to grab the next roll of paper. This means that users in the toilet do not need to touch the roll holder with dirty hands at all, and can simply grab the consumable paper, making it very hygienic. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2023-3885 [Patent Document 2] Patent Publication No. 2022-99421 [Patent Document 3] Utility model registration No. 3233152 DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0004] Some conventional roll holders allow you to cut off the toilet paper with one hand, and some of these holders have a tongue sticking out to make it easier to grab the next roll of paper. Therefore, the paper with the tongue sticking out is flushed down the toilet after using the toilet, so the toilet paper with the tongue sticking out at that time is flushed away, so it doesn't matter. And since conventional hole holders do not require any touching, they are hygienic. However, even though some conventional roll holders allow you to cut off the toilet paper with one hand, the existing roll holder (9) cannot be cut with one hand, so there was a feeling that it would be a waste to replace it with a conventional roll holder, and so replacement did not proceed.

[0005] Therefore, the retrofit roll cutter of the present invention is attached on top of an existing roll holder, and the weight of the top plate (3) acts as the left hand, allowing the paper (9c) to be cut with one hand, and the cushioning portion (3b) of the top plate (3) has a protruding tongue (9g) making it easy to grip. [Means for solving the problem]

[0006] In order to achieve the above object, the hinge (1) of the post-attachment roll cutter of the present invention is composed of an attachment part (2) and a top plate (3), and the attachment part (2) is a place where it is attached to a wall (9e) with double-sided tape or the like. Meanwhile, the tip of the top plate (3) is provided with a serrated blade (3a).

[0007] A buffer section (3b) is formed on the underside of the top plate (3), and the buffer section (3b) holds down the weight of the top plate (3) of the retrofit roll cutter and the lid (9a) of the existing roll holder (9). The height of the buffer section (3b) is the length of the tongue (9g), which achieved the purpose. Effect of the Invention

[0008] The post-attached roll cutter of the present invention has the following effects. (i) Since it is a retrofit, it does not waste the existing roll holder. (See paragraph 0010 for details) (b) The paper can be cut with one hand. (For details, see paragraph 0013.) (c) The tongue can be extended, making it easy to grab the paper. (See paragraph 0019 for details.) (ii) Since the child can stick out his tongue, he does not touch any unnecessary places. (See paragraph 0019 for details) (e) The structure is simple. (For details, see paragraph 0013.) [Brief description of the drawings]

[0009] [Figure 1] The figure shows a perspective view of the present invention. [Diagram 2] The figure is a side view. [Diagram 3] The figure is a side view after the paper has been cut. [Figure 4] The figure is a side view when the paper is pulled down. [Diagram 5] The figure shows a side view of the roll in a smaller size. [Figure 6] The figure is a side view showing the roll replacement. [Figure 7] The figure is a perspective view showing the peeling portion attached. [Figure 8] The figure is a side view with the peeling portion attached. [Figure 9] The figure is a side view after the paper has been cut. BEST MODE FOR CARRYING OUT THEINVENTION

[0010] The retrofit roll cutter of the present invention is attached on top of an existing roll holder (9) that cannot be cut with one hand, so the existing roll holder (9) is not wasted. The retrofit roll cutter is composed of a hinge (1). The hinge (1) is composed of an attachment part (2) and a top plate (3), and the attachment part (2) is attached to the top of the existing roll holder (9), so if the wall (9e) is tiles or the like, it is attached with double-sided tape or adhesive, and if the wall (9e) is wooden, it is attached with screws, nails, etc.

[0011] On the other hand, the top plate (3) of the hinge (1) needs to be somewhat heavy, and has a blade (3a) at the tip. The blade (3a) is notched like a saw blade, but since it is only used to cut paper (9c), the blade (3a) needs to be sharp enough not to injure the hand. Also, the blade (3a) can cut rubber materials, so it can be attached to the tip.

[0012] The underside of the top plate (3) is equipped with a buffer section (3b), which presses against the lid (9a) of the existing roll holder (9), increasing friction between the inside of the lid (9a) and the roll (9b). When the paper (9c) is pulled upwards, it is stopped by the blade of the lid (9a), and the paper (9c) can be cut by the blade (3a) of the retrofit roll cutter. Therefore, it extends when pulled downwards, and stops when pulled upwards.

[0013] In other words, when the paper (9c) is pulled down, the roll (9b) remains in its original shape, and the blade of the lid (9a) is at a different angle, so the blade does not bend but smooths, allowing the paper to come out smoothly. However, when the paper (9c) is pulled up, the paper (9c) is bent at the tip of the lid (9a) by more than 90 degrees, so it is difficult to pull out due to friction. Furthermore, if the paper (9c) is tilted against the wall (9e) and then tilted to the right, the pulling force is concentrated in one place on the left side of the paper (9c) that hits the rear roll cutter, and the paper (9c) that can no longer withstand the force is cut off from the left end of the blade (3a). Therefore, it can be cut with one hand, and can also be used by people with disabilities who have difficulty using their hands. A rear roll cutter with this function is simple, and it is not easy to find anything simpler.

[0014] The buffer section (3b) maintains the gap between the cover (9a) of the existing roll holder (9) and the top plate (3) of the hinge (1), and the length of the tongue-out (9g) when the paper (9c) is cut is related to the height of the protrusion of the buffer section (3b). Therefore, if the height of the buffer section (3b) is lowered, the tongue-out (9g) becomes shorter, and if the height of the buffer section (3b) is increased, the tongue-out (9g) becomes longer. And since only the tongue-out (9g) is touched, the paper (9c) with the tongue-out (9g) is a consumable item that is flushed down the toilet after using the toilet, so it is not a problem. Therefore, it is hygienic because there is no need to touch the existing roll holder (9) with dirty hands, and these operations can be performed with one hand. Example 1

[0015] The post-attaching roll cutter of the present invention will be described with reference to the drawings. The perspective view of Figure 1 shows the rear-attached roll cutter, and the existing roll holder (9), paper (9c), and handle (9d) are different from those of the present invention, so they are shown with dotted lines to make it easier to imagine the entire rear-attached roll cutter. The figure shows the paper (9c) being pulled toward the wall (9e) and cut.

[0016] Figure 2 is a side view of the same state as Figure 1. When the paper (9c) of the roll (9b) is pulled down as shown in Figure 4, it rotates clockwise, and when the paper (9c) is rotated widely around the blade of the lid (9a), it is ready to be cut from the top right corner, through the tip of the lid (9a) of the existing roll holder (9), through the right end of the blade (3a) at the end of the top plate (3), and at the edge of the wall (9e). The paper (9c) can be easily cut by tilting it to the right.

[0017] The reason why it is easier to cut when tilted to the right is that when cutting the paper (9c) straight, the force is applied to the entire paper (9c) being cut, but when tilted to the right, the force is concentrated on the left end, and the paper (9c) that cannot withstand it cuts from the left end to the right. In order to make the existing roll holder (9) easier to understand, the holder surface on the side has been omitted, and the mechanism that releases the roll (9b) is separate.

[0018] Figure 3 is a side view of the cut paper. The cut paper (9c) hangs down as shown by the dotted line, forming a protruding tongue (9g). When the protruding tongue (9g) paper (9c) is pulled down, the roll (9b) rotates clockwise, pulling out a sufficient length, and when the paper (9c) is rotated upwards significantly, it becomes as shown in Figure 2, and is cut off at the edge of the wall (9e).

[0019] At that time, the tongue-out (9g) part seems to stick to the roll (9b), but once it is at an angle of more than 90 degrees, the folded paper (9c) does not return to its original state, but rather leaves a small gap between the tongue-out (9g) and the tongue-out (9g) paper (9c) is easy to grab and waits for the next cut. Therefore, the part touched by the hand is the previous paper (9c), and the paper (9c) is flushed down the toilet after using the toilet, and the current tongue-out (9g) part is hygienic because it has not been touched by the hand.

[0020] Figure 4 shows the state where the tongue (9g) in Figure 3 is grabbed and the paper (9c) is pulled downward. When the paper (9c) is pulled downward, the roll (9b) rotates clockwise as shown by the arrow, pulling out a sufficient length of the paper (9c), and then the paper (9c) is rotated largely around the tip of the lid (9a) as a fulcrum and cut off at the edge of the wall (9e).

[0021] At that time, when the paper (9c) is pulled down, the blade at the end of the lid (9a) only brushes against the roll (9b), but when cutting the paper (9c), it is bent at 90 degrees at the lid (9a) and fixed in place, and the blade (3a) part of the top plate (3) is at about 70 degrees, but the paper (9c) can be cut because the lid (9a) is locked by the weight of the top plate (3).

[0022] Figure 5 is a side view of the roll (9b) when it becomes smaller. When the roll (9b) becomes smaller, it becomes lighter accordingly, and the friction that existed before acts weaker, but the lid (9a) of the existing roll holder (9) goes down, and the top plate (3) on it also goes down, so the angle of the blade (3a) faces downward, making it easier to cut, so even if the roll (9b) becomes smaller, it can be cut with one hand.

[0023] Figure 6 is a side view when replacing the roll (9b). When replacing, lift up the retrofit roll cutter and the existing roll holder (9), and the cover (9a) of the existing roll holder (9) hooks onto the inside side of the buffer part (3b) attached to the top plate (3) and is fixed in the lifted position. This makes it easy to replace the roll (9b). Example 2

[0024] The actual dimensions and installation method will be explained. Figure 1 is a perspective view of the retrofit roll cutter, which is installed directly above the existing roll holder (9). The installation supports the entire retrofit roll cutter with the mounting part (2), which is 3 to 8 cm long and 12 to 15 cm wide, for a total area of ​​36 to 120 square centimeters.

[0025] If the toilet has a tiled wall (9e), double-sided tape is easy and sufficient for attaching the wall (9e) surface to the mounting part (2). However, the reason why weak double-sided paper is sufficient is that the retrofit roll cutter is attached on top of the existing roll holder (9), so the force applied to the retrofit roll cutter is applied to the existing roll holder (9), and so even if the retrofit roll cutter is attached on top, it is not subjected to much force. Also, if the toilet wall (9e) is made of wood, it is attached with screws and nails.

[0026] The width of the toilet paper roll (9b) is about 12 cm, the width of the lid (9a) of the existing roll holder (9) is about 13 cm, the width of the hinge (1) of the present invention is 13 to 16 cm, and the width of the top plate (3) is also 13 to 16 cm. The length of the top plate (3) to the vertical blade (3a) is 10 to 16 cm, and the top plate (3) needs to have a certain weight, which is 100 to 300 grams, assuming a thickness of 1 to 3 mm metal. If the weight of the top plate (3) is too heavy, there is a possibility that the paper (9c) will tear when pulled down.

[0027] The underside of the top plate (3) is equipped with a buffer part (3b), the height of which is 2 to 5 cm, and the purpose of which is to open up a gap between the lid (9a) of the existing roll holder (9) and the top plate (3). The gap is the length of the protruding tongue (9g) of the paper (9c). Therefore, the shape of the buffer part (3b) is free and there is no particular restriction, but it is better to press the outside of the lid (9a) as much as possible, as this increases the friction between the inside of the lid (9a) and the roll (9b). Example 3

[0028] The installation of the peeling part (3c) will be explained. Figure 7 is a perspective view of the peeling part (3c) installed. In the figure, the retrofit roll cutter is drawn in solid lines, and the existing roll holder (9) and paper (9c) other than that of the present invention are drawn in dotted lines.

[0029] In the case of the roll cutter attached later, the paper (9c) sometimes sticks to the blade (3a) and does not stick out (9g). In that case, the paper (9c) can be easily removed by hooking a finger on the back side of the blade (3a) and removing the paper (9c), but since the purpose is to cut the paper (9c) by grabbing only the part that sticks out (9g), the peeling part (3c) is necessary from a hygienic point of view.

[0030] 8 is a side view of the attached peeling part (3c). The peeling part (3c) is a hinge provided on the buffer part (3b), and its movable range is tilted diagonally from the vertical, which is from 1 o'clock to 3 o'clock on a clock, and when the paper (9c) is pulled, it is pushed by the paper (9c) and is in the 1 o'clock direction.

[0031] Figure 9 is a side view of the cut paper (9c). The weight of the peeling part (3c) pushes the paper (9c) outwards in the 2 o'clock direction, and the cut paper (9c) drops down, creating a tongue-out (9g) state. If the weight of the peeling part (3c) is insufficient, a torsion spring can be used. Other methods include attaching a soft sponge under the blade (3a), or using a corner of a 0.1 mm plastic container to attach it, which makes it easy to use thin plastic to replace the hinge even without a hinge. Example 4

[0032] Provides detailed explanations of symbols and terminology. The hinge (1) is a part of the add-on roll cutter, and connects the mounting part (2) and the top plate (3) with a hinge. The mounting part (2) is a part of the hinge (1) and refers to the lower part of the hinge (1). The mounting part (2) is attached with double-sided tape, adhesive, or screws and is the place where the entire add-on roll cutter is fixed. The top plate (3) is a part of the hinge (1), and is the upper part of the hinge (1), with a blade (3a) on the opposite end from the hinge, and a buffer part (3b) on the underside of the top plate (3). The top plate (3) is made of stainless steel, and it is better for it to have some weight.

[0033] The blade (3a) is a part of the top plate (3) and is located at the tip of the top plate (3). In order to cut the paper (9c) with little force and to prevent the hand from being cut by a sharp blade, the blade has an uneven surface like a saw blade, and the tip must be rounded enough not to pierce the hand. The buffer section (3b) is a part of the top plate (3) and is attached to the bottom of the top plate (3). The buffer section (3b) has the role of pushing the lid (9a) of the existing roll holder (9) with the weight of the entire top plate (3). Conventionally, the lid (9a) of the existing roll holder (9) is held down with the left hand and the paper (9c) is cut with the right hand, but the buffer section (3b) replaces the left hand. Furthermore, the height of the buffer section (3b) is related to the length of the tongue protrusion (9g). When the height of the buffer section (3b) is high, the length of the tongue protrusion (9g) becomes long, and when the height of the buffer section (3b) is low, the tongue protrusion (9g) becomes short. When the roll (9b) is replaced, the buffer section (3b) comes into contact with the lid (9a) and fixes the lid (9a) in the open position. The peeling part (3c) is used to push the paper (9c) off the blade (3a) when the paper (9c) cut by the blade (3a) sticks to it. The blade (3a) can be attached with a hinge as shown in Figure 7, or a soft dishwashing sponge can be cut and pasted on, or a 0.1 mm thick plastic plate can be bent to create the peeling part (3c). In short, when cutting the paper (9c), the peeling part (3c) is out of the way so that it does not get in the way, and when peeling, the paper (9c) can be removed from the blade (3a) with little force.

[0034] The existing roll holder (9) is a commercially available product. The present invention was devised because the existing roll holder (9) does not allow one-handed cutting of the paper (9c), and if the existing roll holder (9) itself could be cut with one hand, this invention would not be necessary, so the one that allows one-handed cutting is a conventional roll holder, and the one that does not allow one-handed cutting of the paper (9c) is a distinguished product from the existing roll holder (9). The lid (9a) is the front plate of the existing roll holder (9), and the rear side is attached to the existing roll holder (9) by a hinge. At the tip of the opposite side where it comes into contact with the roll (9b), a blade is provided to cut the paper (9c), but this blade is no longer necessary as it is provided in the retrofit roll cutter.

[0035] The roll (9b) refers to the entire roll of paper (9c). The paper (9c) refers to a portion of the paper (9c) wound around the roll (9b). The hand (9d) is depicted in dotted lines in FIG. The shaft (9f) is the shaft that supports the roll (9b), and recently some of them have hinges to make it easier to remove the roll (9b). The tongue sticking out (9g) is a paper (9c) that is left sticking out about 5 cm from the existing roll holder (9) so that it is easy to pick up, and in a hygienic way, you only need to pick up that part. The shape of the 5 cm paper (9c) sticking out resembles the shape of a tongue sticking out, and I have previously seen it in a patent document, so I will quote it here.

[0036] The term "retrofit roll cutter" refers to a product that can be installed later. The existing roll holder (9) is left as is, and the retrofit roll cutter is attached on top of it, in order to compensate for the inconvenience of the existing roll holder (9). The conventional roll holder allows the paper to be cut with one hand and is designed to be easily gripped or tongued. If the conventional roll holder is installed, the retrofit roll cutter of the present invention is not necessary. The existing roll holder (9) cannot be cut with one hand, which shows the difference between the conventional and existing roll holders. When using the add-on roll cutter, the blade of the lid (9a) is not used, but rather the blade simply brushes the paper (9c) and is not angled to cut. [Industrial Applicability]

[0037] This add-on roll cutter is not only used in toilets, but is also more hygienic than tissue paper that is left hanging in laboratories and other places where hygiene is a priority. In particular, when cutting paper towels with one hand in the kitchen at home, the paper towels have slits, but since there is nothing to hold them down, if you attach one that does not have a buffer part (3b) on the top plate (3), you can cut the paper towel with one hand while holding a pot or other food, and use that paper towel to wipe the pot.

Claims

[Claim 1] The hinge (1) of the retrofit roll cutter is composed of an attachment part (2) and a top plate (3). The mounting portion (2) fixes the entire rear roll cutter to the wall (9e), The top plate (3) is provided at its tip with a blade (3a), The post-installation roll cutter is characterized in that a buffer portion (3b) is formed on the underside of the top plate (3) and holds down the lid (9a) of the existing roll holder (9).
