[0001] The present invention relates to a toilet paper holder that rotatably supports a roll-shaped toilet paper having a cylindrical core and has a cover for cutting the toilet paper by pressing it from above on the front side of the toilet paper.

Background Art

[0002] In a conventional toilet paper holder, when cutting a roll-shaped toilet paper, since the tip of the toilet paper is hidden by the cover, it is necessary to turn the toilet paper to feed out the tip when using it next. To solve this problem, when pushing a cutter plate to cut the roll paper, the bobbin shaft on which the roll paper is mounted is pushed up by the inclined bearing section, and when the hand is released from the cutter plate, the bobbin shaft with the roll paper is converted into a rotational movement when descending in the magnet type inclined bearing section due to the descending action of its own weight, and an automatic feeding device for the end of the roll paper that automatically feeds out the end of the roll paper by an appropriate dimension is disclosed (for example, see Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the automatic feeding device described in Patent Document 1, since it has a specific configuration such as an inclined bearing and a bobbin shaft with a permanent magnet, it cannot be attached to an existing toilet paper holder and needs to be newly replaced, so there is a problem that the introduction cost is high. )]]

[0005] This invention addresses these issues and aims to provide a toilet paper holder that can inexpensively implement a toilet paper dispensing mechanism at the tip of the toilet paper roll and can be applied to existing toilet paper holders with modifications. [Means for solving the problem]

[0006] To achieve the above objective, the toilet paper holder according to the present invention is a toilet paper holder that rotatably supports a roll of toilet paper having a cylindrical core and has a cover that presses against the toilet paper from above on the front side of the toilet paper to cut the toilet paper, and is characterized by having a pair of support parts that are inserted into the inside of both ends of the core and whose rotation around the central axis of the core is restrained, and a biasing member that is fixed to the upper part of each support part and contacts the upper inner surface of the core when pressed from above by the cover, and biases the upper inner surface with a rotational force from the back to the front.

[0007] The toilet paper holder according to the present invention cuts the toilet paper by pressing the cover against the toilet paper from above when pulling out and cutting a roll of toilet paper. When pressed from above by the cover, the biasing member contacts the upper inner surface of the toilet paper core and biases the upper inner surface with a rotational force from the back to the front. After cutting the toilet paper, when the pressure on the cover is removed, the rotational force from the biasing member causes the upper inner surface of the core to rotate from the back to the front, allowing the tip of the toilet paper to be dispensed. Thus, it has a simple configuration of support and biasing member, and the toilet paper tip dispensing mechanism can be realized inexpensively, and it can also be applied to existing toilet paper holders by modifying them to fix the biasing member to the support.

[0008] In the toilet paper holder according to the present invention, the biasing member consists of a pair of leaf springs shaped by bending a plate material at an acute angle, with the bent portion facing the front and one of the two outer surfaces fixed along the upper part of each support part, and is positioned on the support part such that when pressed from above by the cover, the upper end abuts the upper inner surface of the core and biases the upper inner surface with a rotational force from the back to the front, and the upper end may have an anti-slip feature.

[0009] In this case, a biasing member can be inexpensively constructed using a leaf spring made by bending a plate at a sharp angle. Furthermore, the anti-slip feature facilitates the transmission of the biasing force of the biasing member to the upper inner surface of the core. Since each pair of biasing members is fixed to a pair of support parts, when tearing off toilet paper, by shifting the position where the cover is pressed against the toilet paper towards one of the biasing members, the biasing force of the shifted biasing member becomes greater than that of the other, allowing more toilet paper to be dispensed from that side than from the other. This improves usability according to dominant hand and personal habits. Additionally, by pressing the cover more firmly, the tip of the toilet paper can be dispensed further.

[0010] In the toilet paper holder according to the present invention, the biasing member consists of a pair of opening and closing members shaped by bending a plate material at an acute angle, with the bent portion facing the front and one of the two outer surfaces fixed along the upper part of each support part, and each biasing member is always open with two magnets of the same polarity and repelling each other provided on its two inner surfaces facing each other, and when pressed from above by the cover, the upper end abuts the upper inner surface of the core and the repulsive force of the magnets biases the upper inner surface with a rotational force from the back to the front, and the upper end may have a non-slip surface.

[0011] In this case, the biasing member can be inexpensively constructed using an opening / closing member and magnets, both shaped by bending a plate at a sharp angle. Furthermore, the anti-slip feature facilitates the transmission of the biasing force of the biasing member to the upper inner surface of the core. Since each pair of biasing members is fixed to a pair of support parts, when tearing off toilet paper, by shifting the position where the cover is pressed against the toilet paper towards one of the biasing members, the magnetic biasing force of the shifted biasing member becomes greater than that of the other, allowing for a longer roll of toilet paper to be dispensed from that side. This improves usability according to dominant hand and personal habits. Additionally, by pressing the cover more firmly, a longer roll of toilet paper can be dispensed. [Effects of the Invention]

[0012] According to the present invention, a toilet paper dispenser mechanism can be implemented inexpensively, and a toilet paper holder can be provided that can be applied to existing toilet paper holders with modifications. [Brief explanation of the drawing]

[Figure 2] Figure 1 is an enlarged side view of the main part of the toilet paper holder. [Figure 3] Figure 1 is a perspective view of the toilet paper holder with toilet paper installed. [Figure 4] This is an enlarged side view of the main part of a toilet paper holder according to another embodiment of the present invention. [Figure 5] This is a perspective view of a toilet paper holder according to yet another embodiment of the present invention. [Modes for carrying out the invention]

[0014] Embodiments of the present invention will be described below with reference to the drawings. Figures 1 to 3 show a toilet paper holder according to an embodiment of the present invention. A toilet paper holder is used to rotatably support a roll of toilet paper T having a cylindrical core TS.

[0015] As shown in Figure 1, the toilet paper holder comprises a back panel 1, a pair of side panels 2, a cover 3, a pair of support parts 4, and a pair of biasing members 5. The back panel 1 is a rectangular plate with bolt holes 1a for fixing to the toilet wall. The pair of side panels 2 are each made of rectangular plates. One end of each side panel 2 is fixed perpendicularly to the longitudinal end of the back panel 1, and they face each other parallel to each other on the front side of the back panel 1. Each side panel 2 has a recess 2a that extends vertically inward on the opposing side. The cover 3 is a rectangular plate large enough to cover the space above the space sandwiched between the pair of side panels 2. The cover 3 has a cutter part 3a on its front side edge for pressing against the toilet paper T from above to cut the toilet paper T. The cover 3 is rotatably pivoted on the upper inner side of each side panel 2 near the back panel 1, allowing the cutter part 3a to move up and down.

[0016] Each pair of support parts 4 consists of an elongated plate. Each support part 4 is rotatably pivoted on the lower part of both side walls of each recess 2a and can be positioned in a position where it is housed in each recess 2a and in a position where it protrudes inward from each recess 2a. Each support part 4 is normally positioned in the inwardly protruding position by its own weight. In the inwardly protruding position, each support part 4 protrudes perpendicularly to each side plate 2 and can be positioned with its upper surface horizontal. The pair of support parts 4 are arranged in a straight line in the inwardly protruding position. The pair of support parts 4 are inserted into the inside of both ends of the toilet paper core TS, with rotation around the central axis of the core TS being constrained.

[0017] As shown in FIG. 2, the pair of biasing members 5 each comprise a leaf spring formed by bending a single sheet of flat metal material at an acute angle, for example, an angle of about 30 degrees to 70 degrees, particularly around 45 degrees. Each biasing member 5 has one of its two outer surfaces fixed along the upper part of each support portion 4 with the bent portion 5a facing the front side. When each biasing member 5 is pressed from above by the cover 3, the upper end abuts against the upper inner peripheral surface of the core TS of the toilet paper T, and is arranged on the support portion 4 so as to be bent and bias a rotational force from the back side to the front side with respect to the upper inner peripheral surface. Each biasing member 5 has a slip stopper 5b at its upper end. The slip stopper 5b is made of, for example, a rubber material. As shown in FIG. 3, the toilet paper holder inserts the support portions 4 and the biasing members 5 into the core TS of the toilet paper T, and rotatably supports the toilet paper T.

[0018] Next, the operation will be described. The toilet paper holder inserts the pair of support portions 4 into the core TS of the roll-shaped toilet paper T, and rotatably supports the toilet paper T. When pulling out and cutting the toilet paper T, the cover 3 is pressed against the toilet paper T from above, and the toilet paper T is cut with the tip of the cover 3. In a conventional toilet paper holder, when the toilet paper T is pressed from above by a finger on the cover 3, the toilet paper T is pushed to the back side and moves. When the toilet paper T is cut and the finger is released from the cover 3, when the toilet paper T returns to its original position, the tip of the toilet paper T retracts backward from the cutter portion 3a of the cover 3.

[0019] In contrast, in the toilet paper holder according to the embodiment of the present invention, when the toilet paper T is pressed from above by the cover 3, the biasing member 5 abuts against the upper inner peripheral surface of the core TS of the toilet paper T and biases a rotational force from the back side to the front side with respect to the upper inner peripheral surface. After the toilet paper T is cut, when the pressing force on the cover 3 is removed, the upper inner peripheral surface of the core TS rotates from the back side to the front side by the rotational force of the biasing member 5, and the leading end of the toilet paper T can be fed out so as to protrude forward from the cover 3. Thus, with the simple configurations of the support portion 4 and the biasing member 5, it is possible to realize an inexpensive mechanism for feeding out the leading end of the toilet paper T, and it is also applicable to an existing toilet paper holder by improving and fixing the biasing member 5 to the support portion 4.

[0020] The biasing member 5 can be formed at low cost by a leaf spring formed by bending a plate material at an acute angle. Also, the anti-slip portion 5b can facilitate transmission of the biasing force of the biasing member 5 to the upper inner peripheral surface of the core TS. Since the pair of biasing members 5 are respectively fixed to the pair of support portions 4, when cutting the toilet paper T, by shifting the position where the cover 3 presses against the toilet paper T to one of the pair of biasing members 5, the biasing force of the shifted biasing member 5 can be made greater than that of the other biasing member 5, and the toilet paper T on the shifted side can be fed out longer than the other side. Therefore, the usability can be improved according to the dominant hand, habits, etc. Also, by pressing the cover 3 more strongly, the leading end of the toilet paper T can be fed out longer.

[0021] The biasing member 5 may also consist of a magnet. In this case, as shown in Figure 4, the biasing member 5 consists of a pair of opening and closing members shaped by bending a plate material at an acute angle. The biasing member 5 has one of its two outer surfaces fixed along the upper part of each support part 4, with the bent portion 5a facing the front. Each biasing member 5 is always open, with two magnets 6a and 6b of the same polarity facing each other and repelling one another on its two inner surfaces. When pressed from above by the cover 3, the upper end of each biasing member 5 contacts the upper inner surface of the core TS, and the repulsive force of the magnets biases the upper inner surface with a rotational force from the back to the front. Each biasing member 5 may have an anti-slip 5b at its upper end.

[0022] When magnets 6a and 6b are used in this way, the biasing member 5 can be constructed inexpensively using an opening / closing member with a shape formed by bending a plate material at a sharp angle and magnets 6a and 6b. In addition, the anti-slip 5b makes it easier to transmit the biasing force of the biasing member 5 to the upper inner surface of the core TS. Since each pair of biasing members 5 is fixed to a pair of support parts 4, when cutting off toilet paper T, by shifting the position where the cover 3 is pressed against the toilet paper T to one of the pair of biasing members 5, the biasing force of the biasing member 5 that is shifted is made greater than that of the other biasing member 5, and the toilet paper T on the shifted side can be dispensed longer than the other side. This makes it easier to use according to dominant hand or habits. Also, by pressing the cover 3 harder, the tip of the toilet paper T can be dispensed longer.

[0023] The cutter section 3a may be made from the toilet paper cutter described in Patent No. 7242024 by the present inventor. That is, as shown in Figure 5, it may have a configuration in which a first cutter section is provided along the toilet paper T-side surface of the cover 3 for a predetermined length from one end in the width direction of the toilet paper T attached to the toilet paper holder, and a second cutter section is provided along the opposite side of the cover 3 from the toilet paper T-side for a predetermined length from the other end in the width direction. In this case, it becomes even easier to pull out the toilet paper roll. Furthermore, the toilet paper holder may have a member to prevent the toilet paper T from flipping over.

[0024] The toilet paper holder according to the embodiment of the present invention can be suitably implemented in hospital restrooms, restrooms in elderly care facilities, public restrooms, convenience store restrooms, and the like. [Explanation of symbols]
