Description

[Technical Field]

[0001] The present invention relates to a toilet paper holder for supporting a roll of toilet paper. [Background technology]

[0002] Conventionally, there are horizontal double toilet paper holders that support two rolls of toilet paper side by side in the axial direction. For example, Patent Document 1 discloses a toilet paper holder in which a rod is slidably inserted into a through-hole in a support plate that is hung vertically in the center, and an engaging portion is formed in the center of the rod that can be detachably engaged with the through-hole. As a result, toilet paper is placed on both sides of the support plate by passing toilet paper from both ends of the rod inserted into the through-hole in the support plate. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2000-201855 Summary of the Invention [Problem to be solved by the invention]

[0004] By the way, double horizontal toilet paper holders can support two rolls of toilet paper, so they are often used in toilets used by many people, such as in large stores, because they are less likely to run out of toilet paper.

[0005] However, when two rolls of toilet paper are attached to a horizontal double-row toilet paper holder, the one that is running low is often used first, so one roll is often used first, leaving the other with a lot left over.

[0006] In this case, one roll of toilet paper is gone, so the cleaning staff will have to refill it. As a result, the advantage of the double horizontal toilet paper holder, which allows two rolls of toilet paper to be used, is not utilized, and there is a risk that the workload of the cleaning staff in refilling the toilet paper will not change much.

[0007] The present invention has been made to solve the above-mentioned problems in the prior art, and aims to provide a toilet paper holder that can support two rolls of toilet paper and allow the two rolls to be consumed evenly. [Means for solving the problem]

[0008] The toilet paper holder of the present invention has the following configuration.

[0009] The toilet paper holder of the present invention (e.g., toilet paper holder 1) has a first holder (e.g., first holder 5) and a second holder (e.g., second holder 6) that support toilet paper, and supports two rolls of toilet paper aligned in the axial direction, The first holder includes: A rod-shaped first paper support (e.g., first paper support 20) that is inserted into the center hole of the toilet paper and rotates with the rotation of the toilet paper; a first support plate (for example, a right side surface portion 12) that rotatably supports the first paver support; and The second holder includes: A rod-shaped second paper support (e.g., second paper support 25) that is inserted into the center hole of the toilet paper and rotates with the rotation of the toilet paper; A second support plate (e.g., left side surface portion 17) that rotatably supports the second paver support member; and The rotation of either the first paver support or the second paver support that has rotated first is transmitted to the other, causing the first paver support and the second paver support to rotate together.

[0010] According to the present invention configured in this manner, when the toilet paper is pulled out of the first holder, the first paper support rotates, and that rotation is transmitted to the second paper support, causing the second paper support to rotate. This causes the end of the toilet paper in the second holder to droop. Conversely, when the toilet paper is pulled out of the second holder, the second paper support rotates, and that rotation is transmitted to the first paper support, causing the first paper support to rotate. This causes the end of the toilet paper in the first holder to droop.

[0011] As a result, when a toilet user cuts the toilet paper in the first holder, the end of the toilet paper in the second holder becomes longer than the end of the toilet paper in the first holder. Similarly, when the toilet paper is pulled out from the second holder, the end of the toilet paper in the second holder stops in a state where it hangs down a predetermined length. As a result, the end of the toilet paper in either the first holder or the second holder hangs down longer than the other, which stimulates the next user to try using toilet paper with a longer end hanging down.

[0012] In this way, the toilet paper in the first holder and the toilet paper in the second holder are used alternately, reducing the occurrence of an incident where one roll of toilet paper is consumed first and the other roll is not consumed very often. This makes it possible to consume the two rolls of toilet paper evenly, reducing the workload of the worker in replenishing the toilet paper.

[0013] Furthermore, when the toilet paper is pulled out from either the first or second holder, the other toilet paper also hangs down, allowing the next user to grab the hanging part of the toilet paper and pull it out. This eliminates the need to pull out the end of the toilet paper when pulling it out, and allows the toilet paper to be pulled out without touching any part of the toilet paper other than the part that will be used, improving hygiene and making it easier to pull out the toilet paper.

[0014] Further, the toilet paper holder of the present invention is the toilet paper holder, Further provided is a rotation transmission mechanism (for example, a rotation transmission mechanism 8) that transmits the rotation of one of the first paver support and the second paver support that has rotated first to the other, thereby rotating both the first paver support and the second paver support; The rotation transmission mechanism includes: a release mechanism (e.g., notches 42, 47) that releases the transmission of rotation to the other paver support when either one of the first paver support and the second paver support rotates a predetermined amount; a first main gear (e.g., first main gear 30) fixed to the first paver support; a second main gear (e.g., second main gear 35) fixed to the second paver support; a first sub-gear (for example, first sub-gear 40) meshing with the first main gear; a second sub-gear (e.g., second sub-gear 45) that meshes with the second main gear and rotates together with the first sub-gear, The release mechanism is characterized by having a first missing portion (e.g., missing portion 42) that does not mesh with the first main gear and is formed by missing a portion of the multiple teeth of the first sub-gear, and a second missing portion (e.g., missing portion 47) that does not mesh with the second main gear and is formed by missing a portion of the multiple teeth of the second sub-gear.

[0015] According to the present invention configured in this way, when either the first paper support or the second paper support rotates a predetermined amount, the transmission of rotation to the other is released. For example, when the first paper support rotates a predetermined amount by pulling out toilet paper from the first holder, the transmission of rotation to the second paper support is released, causing the second paper support to stop rotating and the end of the toilet paper in the second holder to hang down a predetermined length. Meanwhile, because the first paper support is rotatable, the toilet user can pull out more toilet paper from the first holder.

[0016] Furthermore, while the first main gear and the second main gear are meshed with the first sub-gear and the second sub-gear, when toilet paper is pulled out and either the first paper support or the second paper support is rotated, the other can also be rotated. Therefore, pulling out one roll of toilet paper causes the end of the other roll to droop. Furthermore, when the first missing portion of the first sub-gear faces the first main gear, or when the second missing portion of the second sub-gear faces the second main gear, the meshing is released, and rotating either the first paper support or the second paper support does not cause the other to rotate. While one roll of toilet paper is being pulled out, the end of the other roll stops in a drooping position by a predetermined length.

[0017] Further, the toilet paper holder of the present invention is the toilet paper holder, The axis of the first sub-gear and the axis of the second sub-gear are aligned, and the first missing portion and the second missing portion are arranged at different positions on a circle centered on the axis.

[0018] According to the present invention configured in this manner, when a user pulls out one roll of toilet paper, the end of the other roll of toilet paper stops in a state where the toilet paper hangs down by a predetermined amount.

[0019] Further, the toilet paper holder of the present invention is the toilet paper holder, The gear further includes a rotation axis (e.g., a rotation axis 50) that passes through the centers of the first sub-gear and the second sub-gear and to which the first sub-gear and the second sub-gear are fixed, the first support plate and the second support plate have hole portions (e.g., elongated hole portions 12b, 17b) into which the rotation shaft is inserted and which support the rotation shaft so as to be movable toward the first main gear and the second main gear, The apparatus further includes a biasing member (for example, rubber 70) that biases the rotation shaft toward the first main gear and the second main gear.

[0020] According to the present invention configured in this manner, by biasing the rotating shaft to which the first sub-gear and the second sub-gear are fixed toward the first main gear and the second main gear, when using toilet paper in one holder and then toilet paper in the other holder, it is possible to make it easier to re-engage the main gear and sub-gear of one holder, which are in a disengaged state.

[0021] Further, the toilet paper holder of the present invention is the toilet paper holder, The first paper support includes an insertion portion (e.g., insertion portion 21) that is inserted into the center hole of the toilet paper, and a rotation shaft portion (e.g., rotation shaft portion 22) that extends from the center of the end face of the insertion portion along the center axis of the insertion portion, The insertion portion is Both end faces are approximately rectangular, When the insertion portion is viewed in the axial direction, the substantially rectangular shape of one end surface is rotated by 90° relative to the substantially rectangular shape of the other end surface, It is characterized by having a trapezoidal side surface extending from the long side of one end face to the short side of the other end face, and another trapezoidal side surface extending from the long side of the other end face to the short side of the one end face.

[0022] According to the present invention configured in this way, when toilet paper is inserted into the insertion part, one end and the other end of the toilet paper become ellipses with different major axes, making it difficult for the insertion part to rotate inside the toilet paper. This makes it possible to stably rotate the insertion part in conjunction with the rotation of the toilet paper. [Effects of the Invention]

[0023] According to the present invention, it is possible to provide a toilet paper holder that can support two rolls of toilet paper and allow the two rolls of toilet paper to be consumed evenly. [Brief explanation of the drawings]

[0025] The present invention will be described in more detail below using preferred embodiments, but the following embodiments are merely examples of realizing the present invention and the present invention is not limited thereto.

[0026] The configuration of a toilet paper holder according to one embodiment of the present invention will be described.

[0027] Fig. 1 is a perspective view showing the appearance of a toilet paper holder 1 in one embodiment of the present invention, Fig. 1(a) is a perspective view from the left side, and Fig. 1(b) is a perspective view from the right side. Fig. 2(b) is a plan view. Fig. 2 is an explanatory diagram showing the configuration of the toilet paper holder 1 in one embodiment of the present invention, Fig. 2(a) is a front view, and Fig. 2(b) is a plan view.

[0028] [Toilet Paper Holder 1 Configuration] The toilet paper holder 1 includes a first holder 5, a second holder 6, and a rotation transmission mechanism 8.

[0029] The first holder 5 and the second holder 6 each support a roll of toilet paper so that it can rotate freely, and are arranged in parallel. The rolls of toilet paper supported by the first holder 5 and the second holder 6 are arranged side by side so that their central axes coincide.

[0030] The first holder 5 comprises a first housing 10 and a first paper support 20. In the following description, the direction along the central axis of the toilet paper will be referred to as the horizontal direction, the direction along the direction in which the toilet paper is viewed from the front as the vertical direction, and the direction along the direction in which the toilet paper is viewed from above as the height direction. The horizontal, vertical, and height directions are perpendicular to each other. The left direction in the horizontal direction will be referred to as the left side or left side, and the right direction will be referred to as the right side or right side. Furthermore, the near side in the vertical direction will be referred to as the front direction or front side, and the far side will be referred to as the rear direction or rear side. Furthermore, the upward direction in the height direction will be referred to as the upside or upper side, and the downward direction will be referred to as the downside or lower side.

[0031] The first housing 10 is a box-shaped body large enough to insert toilet paper inside, with the left side and bottom open, and has an upper surface portion 11 that covers the top side of the toilet paper, a right side surface portion 12 that covers the right side of the toilet paper, a rear surface portion 13 that covers the back side of the toilet paper, and a front surface portion 14 that covers the front side of the toilet paper.

[0032] The lower end of the front surface 14 is curved in an arc toward the rear, and a sawtooth cut portion 14a is provided at the lower end of the front surface 14. Note that the front surface 14 is omitted in Figure 2(a) to show the internal configuration.

[0033] The right side surface portion 12 has a hole portion 12a and an elongated hole portion 12b. The hole portion 12a is formed in the center of the right side surface portion 12, and the elongated hole portion 12b is formed below the hole portion 12a and extends in the height direction.

[0034] The first paper support 20 has a rod-shaped insertion portion 21 that is inserted into the center hole of the toilet paper, and a rotation shaft portion 22 that extends from the center of the end face of the insertion portion 21 along the central axis of the insertion portion 21.

[0035] To form the insertion portion 21, first draw a long, thin rectangle on one end face of a cylinder that can be inserted into the center hole of the toilet paper. The center of the rectangle is aligned with the center of the circular end face. A similar long, thin rectangle is drawn on the other end face of the cylinder. The rectangle drawn on the other end face is rotated 90 degrees around the center of the rectangle drawn on the one end face. The cylinder is then cut so that the short side of the rectangle drawn on one end face passes through the long side of the rectangle drawn on the other end face, and the cylinder is further cut so that the short side of the rectangle drawn on the other end face passes through the long side of the rectangle drawn on the one end face. This completes the insertion portion 21.

[0036] Thus, both end faces of the insertion portion 21 are approximately rectangular, and when the insertion portion 21 is viewed in the axial direction, the approximately rectangular shape of one end face is rotated 90 degrees from the approximately rectangular shape of the other end face. Furthermore, it has a trapezoidal side extending from the long side of one end face to the short side of the other end face, and a trapezoidal side extending from the long side of the other end face to the short side of the one end face. When toilet paper is inserted into the insertion portion 21, one end of the toilet paper becomes, for example, an ellipse that is long in the horizontal direction, and the other end becomes, for example, an ellipse that is long in the vertical direction, making it difficult for the insertion portion 21 to rotate independently inside the toilet paper. This makes it possible to rotate the insertion portion 21 in conjunction with the rotation of the toilet paper.

[0037] The cutting portion 14 a arranged at the lower end of the front portion 14 is positioned below the first paver support 20 .

[0038] The second holder 6 includes a second housing 15 and a second paver support 25. The first holder 5 and the second holder 6 are mirror images.

[0039] The second housing 15 is a box-shaped body large enough to insert toilet paper inside, with the right side and bottom open, and has an upper surface portion 16 that covers the top side of the toilet paper, a left side surface portion 17 that covers the left side of the toilet paper, a rear side portion 18 that covers the back side of the toilet paper, and a front surface portion 19 that covers the front side of the toilet paper.

[0040] The lower end of the front surface portion 19 is curved in an arc toward the rear, and a sawtooth cut portion 19a is provided at the lower end of the front surface portion 19. Note that the front surface portion 19 is omitted in Fig. 2(a) to show the internal configuration.

[0041] Left side surface portion 17 has hole portion 17a and elongated hole portion 17b. Hole portion 17a is formed in the center of left side surface portion 17, and elongated hole portion 17b is formed below hole portion 17a and extends in the height direction.

[0042] The second paper support 25 has a rod-shaped insertion portion 26 that is inserted into the central hole of the toilet paper, and a rotating shaft portion 27 that extends from the center of the end face of the insertion portion 26 along the central axis of the insertion portion 26. The first paper support 20 and the second paper support 25 have the same shape, with the insertion portion 26 corresponding to the insertion portion 21 and the rotating shaft portion 27 corresponding to the rotating shaft portion 22.

[0043] The rotating shaft 27 is inserted into the hole 17a from the inside of the second housing 15, and the center of the second main gear 35 is fixed to the end of the rotating shaft 27 that protrudes outside the left side surface 17. As a result, the second paver support 25 is rotatably supported on the left side surface 17 in a cantilevered manner, and the rotating shaft 27 and the insertion portion 26 extend vertically to the right from the inner plate surface of the left side surface 17.

[0044] The cutting portion 19 a arranged at the lower end of the front portion 19 is positioned lower than the second paver support 25 .

[0045] The rotation transmission mechanism 8 includes a first main gear 30, a second main gear 35, a first sub-gear 40, a second sub-gear 45, and a rotation shaft 50. The rotation transmission mechanism 8 is disposed between the right side surface 12 of the first holder 5 and the left side surface 17 of the second holder 6.

[0046] The first main gear 30 is fixed to the rotation shaft 22 of the first paver support 20 , and the second main gear 35 is fixed to the rotation shaft 27 of the second paver support 25 .

[0047] The rotating shaft 22 of the first paver support 20 is inserted into the hole 12a from inside the first housing 10, and the center of the first main gear 30 is fixed to the end of the rotating shaft 22 that protrudes outside the right side surface 12. In this way, the first paver support 20 is rotatably supported on the right side surface 12 in a cantilevered manner, with the rotating shaft 22 and the insertion portion 21 extending vertically to the left from the inner plate surface of the right side surface 12. In this embodiment, the first paver support 20 and the first main gear 30 are configured as separate members, but this is not limiting and they may also be formed integrally. This reduces the number of parts and therefore the assembly process.

[0048] The rotation shaft 27 of the second paver support 25 is inserted into the hole 17a from inside the second housing 15, and the center of the second main gear 35 is fixed to the end of the rotation shaft 27 protruding outward from the left side surface 17. In this way, the second paver support 25 is rotatably supported on the left side surface 17 in a cantilevered manner, with the rotation shaft 27 and the insertion portion 26 extending perpendicularly to the right from the inner plate surface of the left side surface 17. In this embodiment, the second paver support 25 and the second main gear 35 are configured as separate members, but this is not limiting and they may also be formed integrally. This reduces the number of parts and therefore the assembly process.

[0049] 2, the first main gear 30 and the second main gear 35 are the same member. The first main gear 30 rotates as the first paver support 20 rotates, and the second main gear 35 rotates as the second paver support 25 rotates. In this way, the first main gear 30 and the second main gear 35 rotate independently.

[0050] The first sub-gear 40 meshes with the first main gear 30, and the second sub-gear 45 meshes with the second main gear 35.

[0051] The rotation shaft 50 is inserted into the center of the first sub-gear 40 and the center of the second sub-gear 45 , and the first sub-gear 40 and the second sub-gear 45 are fixed to the rotation shaft 50 .

[0052] The toilet paper holder 1 further includes a support shaft 60 and a ring-shaped rubber 70.

[0053] The first holder 5 and the second holder 6 have their right side surface 12 and left side surface 17 facing each other, and both ends of the rotating shaft 50 are inserted into the elongated holes 12b and 17b, and the right side surface 12 and left side surface 17 are connected with a predetermined gap between them by multiple support shafts 60. At this time, the first main gear 30 and the second main gear 35 face each other, and the central axis of the first paver support 20, the rotational axis of the first main gear 30, the rotational axis of the second main gear 35, and the central axis of the second paver support 25 all coincide.

[0054] Both ends of the rubber 70 are passed through both ends of the rotating shaft 50, and the center portion is wrapped around the upper parts of the right side surface 12 and the left side surface 17. Here, the elongated hole portions 12b and 17b extend in the height direction, and the holes 12a and 17a are located directly above the elongated hole portions 12b and 17b. Therefore, the rotating shaft 50 is biased by the rubber 70 toward the first main gear 30 and the second main gear 35, i.e., upward, so that the first sub-gear 40 meshes with the first main gear 30, and the second sub-gear 45 meshes with the second main gear 35. In this embodiment, the rubber 70 has been described as an example of a biasing member, but the biasing member is not limited to this, and any elastic member, such as a spring, can be used as the biasing member.

[0055] Toilet paper holder 1 is attached by fixing rear surface 13 to the wall of the toilet with cutting portions 14a, 19a facing downward. The ends of the toilet paper in first holder 5 and second holder 6 hang down from the bottom of first holder 5 and second holder 6.

[0056] [Configuration of main gear and sub gear] FIG. 3 is an explanatory diagram showing the configuration of the first main gear 30 and the first sub gear 40. As shown in FIG.

[0057] The first main gear 30 has 14 teeth 31 protruding radially from the side surface of a disk, and the 14 teeth 31 are arranged at equal intervals in the circumferential direction. Specifically, when the first main gear 30 is viewed in the axial direction, the 14 teeth 31 protrude from every other side of an imaginary regular 20-sided polygon that contacts the inside of the disk.

[0058] The first sub-gear 40 is obtained by removing one tooth 31 from the first main gear 30, and has 13 teeth 41 and a missing portion 42 where one tooth 41 is removed.

[0059] The first main gear 30 and the first sub-gear 40 are in mesh, and the rotation of the first main gear 30 is transmitted to the first sub-gear 40, causing the first sub-gear 40 to rotate. When the missing portion 42 reaches the meshing portion between the first main gear 30 and the first sub-gear 40, the meshing between the first main gear 30 and the first sub-gear 40 is released. When the meshing between the first main gear 30 and the first sub-gear 40 is released, the first main gear 30 rotates freely.

[0060] The configurations of the second main gear 35 and the second sub-gear 45 are the same as the configurations of the first main gear 30 and the first sub-gear 40, and therefore detailed description thereof will be omitted.

[0061] The second main gear 35 has teeth 36. The second sub-gear 45 has teeth 46 and a missing portion 47. The teeth 36 correspond to the teeth 31 of the first main gear 30, and the missing portion 47 corresponds to the missing portion 42 of the first sub-gear 40.

[0062] The second main gear 35 and the second sub-gear 45 are in mesh, and the rotation of the second main gear 35 is transmitted to the second sub-gear 45, causing the second sub-gear 45 to rotate. When the missing portion 47 reaches the meshing portion between the second main gear 35 and the second sub-gear 45, the meshing between the second main gear 35 and the second sub-gear 45 is released. When the meshing between the second main gear 35 and the second sub-gear 45 is released, the second main gear 35 rotates freely.

[0063] When the first sub-gear 40 and the second sub-gear 45 are fixed to the rotation shaft 50 and viewed in the axial direction, the missing portion 42 and the missing portion 47 are located on opposite sides of the centers of the first sub-gear 40 and the second sub-gear 45. For this reason, the missing portion 42 and the missing portion 47 do not face the first main gear 30 and the second main gear 35 at the same time.

[0064] In this embodiment, the first sub-gear 40 and the second sub-gear 45 are configured as separate members, but this is not limiting and they may be formed integrally. This makes it possible to omit the rotation shaft 50 and reduce the number of parts, thereby reducing the number of assembly steps.

[0065] [Toilet paper holder 1 operation] Next, the operation of the toilet paper holder 1 will be described.

[0066] FIG. 4 is an explanatory diagram showing the operation of the toilet paper holder 1 when toilet paper is pulled out from the first holder 5, and FIG. 5 is an explanatory diagram showing the state of each gear corresponding to the operation shown in FIG.

[0067] First, as shown in Fig. 4(a), toilet paper 100 is set in each of the first holder 5 and the second holder 6, and the toilet paper 100 is pulled downward from the first holder 5. At this time, the first main gear 30 starts to rotate, as shown in Fig. 5(a).

[0068] By pulling the toilet paper 100 in the first holder 5 downward as shown in Figures 4(b) and 4(c), the rotation of the first main gear 30 is transmitted to the second main gear 35 via the first sub-gear 40, the rotation shaft 50, and the second sub-gear 45, as shown in Figures 5(b) and 5(c), and the second main gear 35 rotates in the same direction and by the same angle as the first main gear 30, thereby rotating the second paper support 25. This causes the toilet paper 100 in the second holder 6 to rotate and hang down the same length as the toilet paper 100 in the first holder 5.

[0069] By further pulling the toilet paper 100 from the first holder 5 downward as shown in Fig. 4(d), the missing portion 42 reaches the meshing portion between the first main gear 30 and the first sub-gear 40 as shown in Fig. 5(d), and the meshing between the first main gear 30 and the first sub-gear 40 is released. As a result, the rotation of the first main gear 30 is not transmitted to the second main gear 35 by the first sub-gear 40, the rotation shaft 50, and the second sub-gear 45, and the second main gear 35 stops rotating. Therefore, the first main gear 30 rotates freely, making it possible to pull out the toilet paper 100 from the first holder 5, while the drooping of the toilet paper 100 from the second holder 6 is stopped.

[0070] FIG. 6 is an explanatory diagram showing the operation of the toilet paper holder 1 when toilet paper is pulled out from the second holder 6, and FIG. 7 is an explanatory diagram showing the state of each gear corresponding to the operation shown in FIG.

[0071] First, as shown in Fig. 6(a), toilet paper 100 is set in each of the first holder 5 and the second holder 6, and the toilet paper 100 in the second holder 6 is pulled downward. At this time, as shown in Fig. 7(a), the second main gear 35 starts to rotate.

[0072] By pulling the toilet paper 100 in the second holder 6 downward as shown in Figures 6(b) and 6(c), the rotation of the second main gear 35 is transmitted to the first main gear 30 via the second sub-gear 45, the rotation shaft 50, and the first sub-gear 40, as shown in Figures 7(b) and 7(c), and the first main gear 30 rotates in the same direction and by the same angle as the second main gear 35, thereby rotating the first paper support 20. This causes the toilet paper 100 in the second holder 6 to rotate and hang down the same length as the toilet paper 100 in the second holder 6.

[0073] By further pulling out the toilet paper 100 from the second holder 6 downward as shown in Figure 6(d), the missing portion 47 reaches the meshing portion between the second main gear 35 and the second sub-gear 45 as shown in Figure 7(d), and the meshing between the second main gear 35 and the second sub-gear 45 is released. As a result, the rotation of the second main gear 35 is not transmitted to the second main gear 35 by the second sub-gear 45, the rotation shaft 50, and the first sub-gear 40, and the first main gear 30 stops rotating. Therefore, the second main gear 35 rotates freely, making it possible to pull out the toilet paper 100 from the second holder 6, while the drooping of the toilet paper 100 from the first holder 5 is stopped.

[0074] [Action and effect] According to the toilet paper holder 1 of this embodiment configured in this manner, when a toilet user pulls out toilet paper 100 from either the toilet paper 100 in the first holder 5 or the toilet paper 100 in the second holder 6, a certain amount of toilet paper 100 hangs down from the other holder.

[0075] As a result, when a user uses the toilet paper 100 in the first holder 5 and cuts it, for example, the toilet paper 100 in the second holder 6 extends further downward than the toilet paper 100 in the first holder 5. This makes it possible for the next user to be motivated to use the toilet paper 100 in the second holder 6, and to increase the likelihood that they will use the toilet paper 100 in the second holder 6. When a next user uses the toilet paper 100 in the second holder 6 and cuts it, the toilet paper 100 in the first holder 5 extends further downward than the toilet paper 100 in the second holder 6. This makes it possible for the next user to be motivated to use the toilet paper 100 in the first holder 5, and to increase the likelihood that they will use the toilet paper 100 in the first holder 5.

[0076] In this way, the toilet paper 100 in the first holder 5 and the toilet paper 100 in the second holder 6 are used alternately, reducing the occurrence of an event where one toilet paper 100 is consumed first and the other toilet paper 100 is not consumed much. This allows both toilet papers 100 to be used evenly, and as a result, it is possible to reduce the frequency of replenishing the toilet paper 100, reducing the workload of workers replenishing the toilet paper 100.

[0077] Furthermore, since the notched portions 42 and 47 are located on opposite sides of the rotating shaft 50, when a user pulls out one piece of toilet paper, the end of the other piece of toilet paper can hang down halfway around the toilet paper.

[0078] In addition, by using the rubber 70 to bias the rotating shaft 50 toward the first main gear 30 and the second main gear 35, it becomes easier to re-engage the first main gear 30 and the first sub-gear 40, which are in a disengaged state, for example, when using the toilet paper 100 in the second holder 6 after using the toilet paper 100 in the first holder 5.

[0079] Additionally, the cutting portions 14a, 19a located at the lower ends of the front portions 14, 19 are positioned lower than the first paper support 20 and the second paper support 25. Therefore, when toilet paper is pulled out from the first holder 5 and the second holder 6 and cut using the cutting portions 14a, 19a, the end of the toilet paper is separated from the roll-shaped main body. This makes it possible to stably hang down the end of the toilet paper when rotation is transmitted by the rotation transmission mechanism 8 and the first paper support 20 or the second paper support 25 rotates.

[0080] Although the embodiments of the present invention have been described above, the embodiments of the present invention are not limited to the above-described embodiments. For example, according to the above-described embodiments, the first sub-gear 40 and the second sub-gear 45 are disposed below the first main gear 30 and the second main gear 35. However, the present invention is not limited to this. The first sub-gear 40 and the second sub-gear 45 may be disposed above the first main gear 30 and the second main gear 35. This causes the first sub-gear 40 and the second sub-gear 45 to move toward the first main gear 30 and the second main gear 35 due to their own weight, thereby enabling the first sub-gear 40 and the second sub-gear 45 to mesh stably with the first main gear 30 and the second main gear 35.

[0081] Furthermore, a modified example of the first sub-gear 40 is a first sub-gear without missing portion 42 (no missing teeth 31), and a modified example of the second sub-gear 45 is a second sub-gear without missing portion 47 (no missing teeth 46). These integrally formed members may be provided instead of the first sub-gear 40, the second sub-gear 45, and the rotation shaft 50. In this case, when toilet paper is pulled out from either the first holder 5 or the second holder 6, the same amount of toilet paper will hang down from the other. By making such a member interchangeable with a member integrally formed with the first sub-gear 40 and the second sub-gear 45, it is possible to switch between a mode in which the first holder 5 and the second holder 6 are synchronized and the same amount of toilet paper hangs down, and a mode in which when toilet paper is pulled out from one, a fixed amount of toilet paper hangs down from the other.

[0082] Furthermore, the shapes of the insertion portions 21, 26 of the first paper support 20 and the second paper support 25 can be any shape that prevents the inner surface of the toilet paper core from slipping between the insertion portions 21, 26 when the toilet paper is rotated. For example, as shown in Figure 8, a columnar body with a hexagonal base that abuts the inside of an ellipse, or a columnar body with a chamfered rectangular base, may be used. As a result, when the toilet paper is inserted into the insertion portions 21, 26, the toilet paper core deforms into an elliptical shape, and therefore the insertion portions 21, 26 rotate stably when the toilet paper is rotated.

[0083] Furthermore, holes into which a tool such as a screwdriver can be inserted may be formed on the side surfaces of the insertion portions 21, 26 of the first paver support 20 and the second paver support 25. This makes it possible, for example, when fixing the toilet paper holder 1 to a wall surface with screws or the like, to insert a tool such as a screwdriver into the holes in the insertion portions 21, 26 and tighten the screws or the like to fix it to the wall surface, thereby improving workability.

[0084] The present invention is not limited to the above-described embodiment, and modifications and improvements within the scope of achieving the object of the present invention are included in the present invention. [Explanation of symbols]
