PROBLEM TO BE SOLVED: To provide a toilet tissue holder that can control generation of a sound of rotating a core tube when rolling a toilet paper out or an abnormal sound during an operation of rolling out.SOLUTION: The toilet paper holder 10 includes: a fixed supporting shaft 2 that extends from an end of a side plate 11 to the inside; a rotating body 3 that is freely rotationally arranged at the fixed supporting shaft 2 and has a smaller maximum diameter than an inner diameter of the core tube 91 of the toilet paper 9; and a spring member 4 that is arranged at the rotating body 3 and always performs a pressure welding to an inner face of the core tube 91 by a spring biasing.

Description

  The present invention relates to a toilet paper holder that can suppress the generation of abnormal noise during unwinding operation or rotating sound of a core tube when unwinding toilet paper.

  In apartment houses such as apartments and apartments, when toilet paper is unwound, when the toilet paper is unrolled, the rotating sound of the core tube of the toilet paper or the unusual sound during unwinding operation may reach the neighbor's ears along the wall. For this reason, development of what is called a mute toilet paper holder which suppressed generation | occurrence | production of such abnormal noise is desired.

  The conventional toilet paper holder has a smaller support shaft diameter than the inner diameter of the core tube, so when winding the paper, the rotating shaft is eccentric and the paper itself bounces up and down, which causes various noises. It has become.

  The silencer toilet paper holder is a toilet paper holder in which a paper presser is pivotally pivoted between a pair of opposing side plates and a support shaft for supporting the core tube of the toilet paper protrudes from the side plate. A paper cutter provided with a cutter part is provided so as to be movable with the paper presser, the cutter part is arranged to be spaced apart from the edge of the paper presser, and the support shaft is arranged obliquely with respect to the side plate. A toilet paper holder is disclosed (Japanese Utility Model Laid-Open No. 5-21795). According to the toilet paper holder described in Japanese Utility Model Laid-Open No. 5-21795, since the core tube is supported in a point contact state, the contact space with respect to the support shaft can be minimized and can be used to support the deformed core tube. At the same time, it is possible to suppress the generation of abnormal noise during the rotating sound of the core tube and the unwinding operation.

Japanese Utility Model Publication No. 5-21795 (Claim 1)

  However, the conventional silencing measures for toilet paper holders are not yet sufficient, and there has been a demand for the development of toilet paper holders having a new silencing structure with a higher silencing effect.

  That is, an object of the present invention is to provide a toilet paper holder capable of suppressing the generation of abnormal sound during the unwinding operation or the rotating sound of the core tube when unwinding the toilet paper.

  In such a situation, the present inventor has intensively studied. As a result, if the inner peripheral surface of the paper core tube is always pressed by an elastic force such as a spring bias, the core is unwound when unwinding the toilet paper. It has been found that the generation of abnormal noise during tube rotation and unwinding operations can be suppressed, and the present invention has been completed.

  That is, the present invention includes a fixed support shaft that extends inward from the tip of the side plate, a rotating body that is rotatably attached to the fixed support shaft and has a maximum diameter that is smaller than the inner diameter of the core tube of toilet paper, and the rotation The toilet paper holder is provided with an elastic member that is attached to the body and constantly presses the inner peripheral surface of the core tube with an elastic force.

  According to the present invention, since the elastic member that constantly presses the inner peripheral surface of the paper core tube with an elastic force such as a spring bias is attached to the rotating body, even if the size of the paper core tube is slightly different, The rotation axis is stable. Therefore, when unwinding the toilet paper, the rotation sound of the core tube and the generation of abnormal noise during unwinding operation can be suppressed.

  Next, a toilet paper holder (hereinafter also simply referred to as “paper holder”) according to an embodiment of the present invention will be described with reference to FIGS. In this specification, the front means the direction of viewing the wall surface from the use side. In FIGS. 5 and 8, most of the outer cylinder is omitted so that the internal structure can be seen. In FIG. 7, 1/4 parts in the circumferential direction including the fixed support shaft are omitted so that the spring member in the fitting groove can be seen. 5 and 7 and FIGS. 8 to 12 are simplified drawings mainly showing a rotating body and a fixed support shaft. The paper holder 10 includes a cutter member 5 for a paper cutter that is rotatably attached to a base 6 that is fixed to a wall surface, a fixed support shaft 2 that extends inward from the tip of the side plate 11, and a fixed support shaft 2. The rotating body 3 is rotatably attached and has a maximum diameter smaller than the inner diameter of the core tube 91 of the toilet paper 9, and the rotating body 3 is attached to the rotating body 3 and the inner peripheral surface of the core tube 91 is spring-biased (elastic force). A spring member (elastic member) 4 that is always in pressure contact. In the present invention, the term “elastic force” refers to the force exerted on the other object as a reaction by a deformed object. For example, in the case of a spring member, the force exerted on the other as a reaction is an urging force by the spring, and in the case of a rubber member, the force exerted on the other as a reaction is a repulsive force by rubber. Hereinafter, the case where the elastic member is a leaf spring member will be described.

  In the paper holder 10, the base 6 includes a wall surface contact surface 61, an attachment surface 62 to which the L-shaped support main body 1 is attached, and a shaft hole 63 to which the cutter member 5 is attached. If a vibration isolating material (not shown) is interposed between the wall surface 61 and the wall surface, it is possible to prevent the generation of slight noise during the paper unwinding operation. A known rubber material or the like can be used as the vibration isolator.

  The cutter member 5 is screwed to both end attachment portions of the shaft 7 that is pivotally supported by the shaft hole 63 of the base 6. If a resin material, which is a low friction material, is used for either or both of the inner peripheral surface of the shaft hole 63 and the outer peripheral surface of the shaft 7, rotational friction can be reduced, and abnormal noise due to the rotation of the cutter member 5 can be reduced. Occurrence can be prevented. Further, since the cutter member 5 is screwed to the shaft 7, it is possible to prevent rattling at the time of paper unwinding operation and paper cutting.

  The L-shaped support main body 1 includes a base 12 that is a substantially plate-like member that is screwed to the mounting surface 62 of the base 6, and a side plate 11 that extends forward from the left end of the base 12. By using the L-shaped support main body 1, installation on the base 6 is simple and free of rattling, and new paper can be easily attached. A screw hole 112 for screwing a buried bolt attached to the end of the fixed support shaft 2 is formed at the tip of the side plate 11.

  The fixed support shaft 2 is a round bar member, and an embedded bolt 29 protruding outward from the end surface is formed on the end surface on the side plate 11 side (attachment side) to enable screwing of the side plate 11 and the fixed support shaft 2. Yes. Further, a single circumferential groove 21 is formed in the vicinity of both ends of the fixed support shaft 2. The circumferential groove 21 engages with the protruding strips 86 formed on the cap members 8a and 8b fitted to both ends of the rotating body 3, and reduces friction caused by unwinding of the paper as much as possible and is stable. The rotation is maintained. That is, the contact between the fixed support shaft 2 and the rotating body 3 is only the engagement between the circumferential groove 21 and the protruding piece 86.

  The rotating body 3 is attached to the fixed support shaft 2 so as to be rotatable, and has a function of attaching a spring member 4. The rotating body 3 includes an outer cylinder 301, an inner cylinder 32, a rotating body main body 3A including three connecting portions 33 formed at equal pitches in the circumferential direction connecting the outer cylinder 301 and the inner cylinder 3, and a rotating body. Cap members 8a and 8b whose outer shapes that fit into the openings at both ends of the main body 3A are substantially cylindrical are provided. By making the rotator 3 have a double tube structure, the rigidity of the rotator is increased. Further, a fitting groove 36 into which a spring member 4 described later is fitted is formed in the connecting portion 33 and the outer cylinder 301 corresponding to the connecting portion 33. Further, by using the cap members 8a and 8b, contact between the rotating body main body 3A and the fixed support shaft 2 can be avoided, and the number of frictional resistance points can be reduced.

  The inner cylinder 32 has an inner diameter slightly larger than the outer diameter of the fixed support shaft 2, and the length is smaller than the length of the outer cylinder 301. By making the length of the inner cylinder 32 smaller than the length of the outer cylinder 301, a space can be secured in the opening portions at both ends, and the circumferential groove 21 of the fixed support shaft 2 can be positioned in this space to accommodate the caps 8a and 8b. I am doing so.

  The three connecting portions 33 include two long wall portions that are long in the axial direction and extend from the outer peripheral surface of the inner tube 32 toward the outer tube 301. In addition, a groove having a gap corresponding to the space between the two wall portions is cut out in the outer cylinder 301. For this reason, the outer cylinder 301 is formed with bottomed fitting grooves 311 having an equal pitch (at intervals of 120 degrees) in the circumferential direction. The groove width of the fitting groove 311 is larger than the thickness of the spring member 4 so that contact friction due to vertical movement of the spring member 4 does not occur. The fitting groove 311 has a predetermined length from the opposite side plate side (right side) and is smaller than the length of the outer cylinder 301. That is, the fitting groove 311 is a part of the outer cylinder 301 cut out, and is a partial groove extending from the middle of the left end of the outer cylinder 301 to the right end. By using such a fitting groove 311, the tip end of the protrusion 412 on the side opposite to the plate of the spring member 4 can be substantially coincided with the right end of the rotating body main body 3 </ b> A, and the attachment position of the paper 8 can be determined. it can. Further, standing projections 37 and 37 are formed at both ends of the bottom surface of the fitting groove 311 to restrict the spring member 4 from being bent excessively. Further, on the opposite side plate side (right side) of the fitting groove 311, it is outside the protrusion 37 of the fitting groove 311, and is a position for connecting the two wall portions to a position slightly above the fitting groove bottom surface. A stop 35b is formed. The locking member 35b is locked with the locking piece 43b of the spring member 4, thereby preventing the spring member 4 from falling off.

  The structure of the opening portions on the left and right ends of the rotating body main body 3A is different. This is because the opening on the side opposite to the side plate is such that the head of the hook-shaped tip of the spring member 4 is cueing into the opening space, and the spring member 4 is not located at the opening end on the side plate side. . That is, the opening at the right end of the rotating body main body 3A is in the outer cylinder 301 and outside the end of the inner cylinder 32 there is a cylindrical space, and the spring member 4 is fitted into the spring member 4. The hook-shaped protrusion at the tip of the head is positioned in the space, and the tip of the fixed support shaft 2 is cued. On the other hand, the opening end on the side plate 11 side is an inner peripheral surface of the outer cylinder 301, and three columnar protrusions 34 connected to the connecting portion 33 are provided at an equal pitch in the circumferential direction. Further, the inner end of the protrusion 34 stops slightly outside the protrusion 37 of the fitting groove 311, and forms a locking portion 35 a to which the locking piece 43 a of the spring member 4 is locked. As described above, the protrusions 34 formed at an equal pitch in the circumferential direction are fitted into the concave portions of the cap members 8a and 8b.

  The rotating body 3 has an outer diameter (maximum diameter) smaller than the inner diameter of the paper core tube 91. As a result, when the paper 9 is mounted, a gap is formed between the core tube 91 of the paper 9 and the rotating body 3, and direct contact is avoided and the leaf spring bias of the spring member 4 to the core tube 91 is avoided. Can be achieved.

  The spring member 4 is a separate member from the rotating body 3 and has a thickness of, for example, about 5 mm, which is smaller than the width of the fitting groove 311 of the rotating body 3. Further, the spring member 4 has a plate-like portion 41 whose upper end surface is in contact with the inner peripheral surface of the core tube 91 and extending in a longitudinal direction by a predetermined length, and a leg portion 42 a that extends downwardly from the lower end of the plate-like portion 41. 42b. The height of the plate-like portion 41 (the length extending in the radial direction) is such that the lower portion of the plate-like portion 41 is a fitting groove even when the spring member 4 is unloaded (in the case of FIG. 1 where no paper is mounted). The state hidden in 311 is preferable in that the spring member 4 can move smoothly without being caught in the fitting groove 311 when the paper 9 is mounted.

  In this example, the leg portions 42a and 42b are slightly curved so as to protrude slightly upward from the approximate center in the length direction of the plate-like portion 41 toward the end direction (opposite to each other) and slightly downward. The spring force that opposes this pressing is expressed by being pressed from above. In the spring member 4, the maximum deformation amount in the vertical direction is preferably about 5 mm.

  The upper ends of both ends of the plate-like portion 41 of the spring member 4 are chamfered. Thereby, the inner peripheral surface of the core tube 91 of the paper 9 is not damaged, and the paper 9 can be mounted smoothly. At the end on the side plate side of the spring member 4, a locking piece 43 a is formed that extends slightly downward from the end of the plate-like portion 41 and has a tip slightly protruding outward. The locking piece 43 a is locked to the locking portion 35 a of the rotating body 3, thereby preventing the spring member 4 from protruding upward. Further, a locking piece 43b is formed in the middle of the spring member 4 on the side opposite to the side plate, extending slightly downward from the lower end of the plate-like portion 41 and projecting its tip slightly outward. The locking piece 43b is locked to the locking portion 35b of the rotating body 3, thereby preventing the spring member 4 from protruding upward. The end of the spring member 4 on the side opposite to the side plate has a protrusion 413 that extends slightly downward from the tip. The recess of the cap member 8b is fitted into the protrusion 413 (see FIG. 3).

  The cap members 8a and 8b are substantially cylindrical with a bottom, and three recesses 81a and 81b are formed at an equal pitch in the circumferential direction. The protrusions 34 of the rotator 3 and the protrusions 413 of the spring member 4 are fitted in the recesses 81a and 81b, respectively, and the cap members 8a and 8b and the rotator 3 rotate together during the paper unwinding operation. It is supposed to be. Each of the cap members 8a and 8b has a through hole 84 through which the fixed support shaft 2 penetrates in the center portion in the radial direction, and is extended from the periphery of the through hole 84 to the inside (axial direction in the axial direction). A protrusion 86 is provided. A protruding strip 87 extending in the circumferential direction is formed on the inner peripheral surface of the protruding piece 86. Since the protrusions 87 are engaged with the circumferential grooves 21 of the fixed support shaft 2, the fixed support shaft 2 and the cap members 8 a and 8 b are rotatably locked while maintaining the axial position. . The cap members 8a and 8b, in particular, the protrusions 87 are made of a resin of a low friction material, so that the circumferential groove 21 and the protrusions 87 are locked and rotated very smoothly, and even if the paper is unwound. Sound generation can be suppressed.

  In the paper holder 10, when the paper is not mounted, the plate-like portion 41 which is the upper member of the spring member 4 is about 3 to 5 mm from the rotating body 3 as shown in FIGS. 1, 3, 9 and 11. It is in a cueing state. The diameter (imaginary) formed at the upper end of the spring member 4 in the cueing state is larger than the inner diameter of the core tube 91 of the paper 9. In this state, new paper 9 is inserted into the fixed support shaft 2 from the right side to the left side in FIG. At this time, the core tube 91 of the paper 9 is inserted so as to push in the spring member 4. A state after the paper 9 is mounted is shown in FIGS. In this state, the spring member 4 always presses the inner peripheral surface of the core tube 91 by spring bias. For this reason, the rotating body 3 and the paper 9 are integrated, and the rotating body 3 and the paper 9 become an integrated rotating object. When the paper 9 is unwound, the rotating body 3 rotates with the fixed support shaft 2 as a fixed shaft. At this time, since the locking of the rotating body 3 and the fixed support shaft 2 is the protruding strip 87 and the circumferential groove 21 formed on the cap member, the rotating body 3 does not swing in the axial direction, and friction is reduced. Smooth rotation is possible. For this reason, generation | occurrence | production of the abnormal noise by unwinding of the paper 9 is almost eliminated. Even if a slight abnormal noise occurs, the abnormal noise is absorbed by the vibration isolator interposed between the paper holder 10 and the wall surface.

  The paper holder 10 is not limited to the embodiment described above, and various modifications can be made. The rotating body is not limited to the above-described circular cross-section cylinder, and may be a rectangular body or a cylindrical body having an indefinite cross section. When the rotating body is a cylindrical body having a square cross section or an irregular cross section, the maximum diameter refers to the maximum diameter in the radial direction passing through the center in the cross-sectional shape. Even if the rotating body is a cylindrical body having an irregular cross-sectional shape, the spring member always presses the inner peripheral surface of the core tube of the paper, so that the rotating shaft of the rotating body is stable.

  In the paper holder of the present invention, the spring member is not limited to the above-described embodiment, and may be an elastic member such as rubber or resin. In this case, the elastic member is incorporated into the core tube of the paper so that the inner peripheral surface of the core tube is always in pressure contact. Examples of the elastic member include a cylindrical elastic member having an outer diameter that is slightly larger than the inner diameter of the paper core tube and having a shaft hole into which the fixed support shaft is fitted. In addition, what is necessary is just to apply | coat an adhesive agent to the internal peripheral surface of a shaft hole, and to fix to a fixed support shaft. Further, when the elastic member is a spring member, the spring member and the rotating body are not separate members, and the spring member and the rotating body may be integrated.

  In the paper holder 10, the number of spring members 4 installed is not limited to the above three, and may be two or four or more. In this case, the fitting grooves are formed in a number corresponding to the number of installation. Further, the shape of the spring member is not limited to the above shape, and the upper surface of the plate-like portion may be an arc with a large curvature. The arch shape may be slightly projecting downward or slightly projecting upward.

  In the paper holder 10, the formation position of the fitting groove is not limited to the above position, and may be the center of the rotating body. In this case, the structure around the opening at the right end of the rotating body may be the same as the structure around the opening at the left end.

  According to the present invention, when unwinding toilet paper, it is possible to suppress the generation of abnormal noise during rotation of the core tube and during unwinding operation, so that abnormal noise is not transmitted to the neighbor along the wall. For this reason, the toilet can be used safely at night, which is convenient. It is particularly effective when using toilets in condominiums such as condominiums and apartments for the elderly.
