Abstract

PROBLEM TO BE SOLVED: To provide a toilet paper holding tool not causing unpleasant sound production.SOLUTION: The rotation shake of rolled paper is corrected by integrating a truncated cone support material having a rotational axis with the rolled paper by fitting and holding by a spring force from the right and left to a rolled paper core hole, and simultaneously, compensating an eccentricity by a buffer structure of the truncated cone support material. For a case caused by a warp of the rolled paper, the pressure plate from an upper side is floated by a spring force and structured in constantly non contact to the rolled paper so as to prevent the production of unpleasant sound by the pressure plate. The truncated cone support material is linked to a rotation axis to be laterally opened, and is formed so as to hold the rolled paper and attach/remove with one hand while pushing up.

Description

  The present invention relates to a toilet paper roll holder.

  The core of roll-type toilet paper is usually a thick paper tube, but without using this paper tube, the paper itself forms a through-hole, that is, there is a paperless tube. In homes and the like, an idle shaft of a paper holder is inserted into a through hole, which is a roll paper core hole, and is supported by idling.

  The inner diameter of the roll paper core hole is not constant, and it is usually an irregular shape that varies depending on the manufacturer. From this reality, the roll paper is used idly on the idle shaft or is used for a holder that does not use the idle shaft. It can be considered that the product specification is used in the configuration.

In the case of paperless tube rolls, there are many cases in which the core hole is distorted, which is considered to be a cause in the manufacturing process, but such products are also normally distributed.
In addition, the roll paper itself is often deformed by an external force in the course of physical distribution, and is distributed as a defective deformed product regardless of the intention of the manufacturer.

  There are many cases where the end of the paper tube is crushed and the projection is partially formed, or the circular shape is distorted. However, even if the consumer wants to select a good quality item at the time of purchase, it can be seen on the package. There is usually no situation.

  As a conventional technology for shaft support, it is a general holding fixture situation that an idle shaft that is significantly thinner than the diameter of the roll core hole is inserted, and an idle shaft structure in which roll paper slides on the support shaft. For some reason, there is a potential root cause of unpleasant noise.

  In the prior art documents 1 and 2, in either case, the roll paper core hole is sandwiched and held by acting an elastic material with a hemispherical holding member.

  From conventional paper holders, generally unpleasant sounds, that is, actions, actions, actions, etc. in the toilet room are converted into unique sounds, sometimes the holders and walls resonate and the sound It is a noise that is enlarged and unintentionally transmitted to the outside, and the causes of these noises are different and complex, so it is important to accurately grasp each cause. These problems are solved and the generation of unpleasant noise is eliminated comprehensively.

As one of the causes, the diameter of the idling shaft that is conventionally inserted into the inner diameter of the roll paper core hole is thin, and the difference in the shaft pair diameter is a large space. Some things are generally square rather than round bars. From such a combination, when the paper is pulled out, the roll paper tube generates frictional noise and rocking noise while frictionally rotating on the idle shaft.
In addition, when the roll paper core hole is deformed as a product or there is a defect such as a protrusion formed at the paper tube corner, the roll paper cannot smoothly idle on the idle shaft and passes through the deformed part. When this occurs, the roll paper becomes a turbulent rotation that dances up and down in this space, so that a large noise is generated between the idle shaft and the roll paper.

  As a cause 2, in the distribution process in which a certain amount of roll paper is packed, an external force that is excessively tightened results in a product having a habit of an ellipse or a quadrangle. When this is set on the holder and the paper is pulled out, the presser plate that is rotating on the roll paper in a non-rotating manner causes a faithful vertical movement like a cam mechanism, and produces sound from the presser plate. There is also a case where a maximum of 4 sounds are produced by one rotation of the paper.

The third reason is that the vibration caused by the weight of the roll paper due to the rotation of the roll paper causes a low-frequency sound that resonates with the bracket and the partition wall of the toilet where it is attached. There is also a loud sound, which becomes a continuous sound due to the momentum when pulling out the paper, and it becomes an unpleasant sound that reverberates inside and outside the room.
An object of the present invention is to obtain a paper holder that does not generate various unpleasant noises, including cases where these causes are combined.

  In Patent Documents 1 and 2 of the prior art, the pinching portion for pinching the roll paper core hole portion is hemispherical, and the spherical surface is contacted and fitted to the edge of the core hole to close the hole. Although holding, fitting, and holding by a spherical surface are held by compression of the contact surface from the left and right to the hole end, the supporting force of the force that is structurally orthogonal to the axis Therefore, it is a holding means that is easily displaced during rotation and lacks certainty.

  This is also a drawback in that it is difficult to position the center of the roll paper between the spherical holding parts that are acting elastically from the left and right, so that it is difficult to position the center of the roll paper. This means that there is a great deal of uncertainty in relying on the position, and it is extremely difficult to put it on the rotation axis in one shot. It is easy to understand that the spherical body will fit in the expected position from the slippery if it is hard, but it will be slippery with a paper cross section vs. plastic body, even if it is slightly shifted, It is simply uncluttered as it is without being naturally corrected, and it is difficult to guide to the axis.

Achieving accurate clamping is extremely important in turning to shaft rotation and preventing unpleasant noise.
In spite of being directly connected to the rotation of the roll paper, the prior art in Patent Documents 1 and 2 does not show a point of view regarding the important rotation and runout. It can be said that the removal of is still incomplete.

Regarding the shape of the holding portion, in Patent Document 2, it is suggested that the contact surface of the holding member may be a cone in addition to adopting the spherical surface.
The outline of the assertion that the hemisphere is pushed by an elastic bracket is that the roll paper is pushed in between the left and right spherical bodies, but the important structure is not disclosed and is completely unknown. When it is replaced, it cannot be understood without explanation how the push-in is realized, and it can be said that it is merely described as possible.
On the other hand, in the present invention, if the cone is used, the upper part of the cone becomes an obstacle, so it is impossible to push in the roll paper, and it is confirmed that the mounting is almost impossible, and the holding portion is configured with a truncated cone shape. However, the present invention is embodied by adding the new ideas described in detail, and solves the problem, which is clearly different from the above-mentioned patent document.

  In Patent Documents 1 and 2, there is no disclosure about the presence of a roll having protrusions or distortion in the portion where the core hole edge is held. However, in reality, there are many protuberances and deformed products that can be surely a source of unpleasant noise, and when a spherical body comes into contact with the object, the roll paper is pinched with its posture collapsed, so that rotational shake is not possible. It is generated and leads to noise generation. Swing and partial rotation are important parts that have not been solved so far, and from this, it is considered that the roll paper having distortion is positioned outside the scope of the present invention in the above document.

  In contrast to the above, the present invention solves this problem and solves this problem. A frustoconical holding body is inserted into the roll paper core hole, and the core hole inner diameter is at one point (one circumference) of the cone outer diameter. In the range of the roll with the smallest core hole diameter to the roll with the largest diameter, the fitting supports the load perpendicular to the axis at a constant angle of the cone regardless of the position at which it is fitted. Combined with the structure, it realizes a high clamping ability to securely hold even distorted roll paper. The certainty of this holding force obtained by the truncated cone holder is a feature of the present invention, and cannot be obtained in the prior art structures of Patent Documents 1 and 2.

Concerning the prevention of unpleasant rotating sound coming out of the toilet paper holder,
The truncated cone holder (1) having a buffer structure is pivotally supported on one end of the rotation spindle (4),
The other end of the shaft is connected to a rotating arm (10) via a joint (9), and this rotating arm (10) constitutes a link supported by the rotating shaft (11),
This pair of links are arranged facing each other from the left and right, the small-diameter side of the truncated cone holder (1) is inserted into the roll paper core hole end (2) from both ends, and is fitted at the conical portion to rotate the spring ( The toilet paper holder is characterized in that the roll paper (3) is sandwiched and held by the urging of 8) and is rotated by the rotating support shaft (4).

  In the buffer structure according to claim 1, the conical surface is made of a silicone resin as a material constituting up to a predetermined depth, and a slit (5) having a V-shaped cross section in the longitudinal direction is provided at an appropriate interval on the entire circumferential surface of the cone. The toilet paper holder is characterized in that the cross-sectional shape of the buffer mountain (6) formed in the trace is formed by a trapezoidal structure having a thick bottom and a thin triangular top or a top side.

Concerning the prevention of unpleasant rotating sound coming out of the toilet paper holder,
The presser plate (13) installed on the swing shaft on the bracket (18) is lifted by the urging force of the support spring (14) and is always in a non-contact configuration with the roll paper (3). This is a toilet paper holder characterized in that the paper can be cut after the roll paper is pressed and fixed.

  In terms of definition, the truncated cone holding body is a sandwiching body having a truncated cone shape, and is a member that fits and holds the roll paper at the end of the roll paper core hole with the two sandwiched bodies and the roll paper at the cone part. is there.

  The buffer mountain shape is a name that represents the solid portion of the mountain shape that is formed by marking the V-shaped slit in the truncated cone holding body made of an elastic material, and the plurality of buffer mountain shapes are expressed as a buffer structure including the V-shaped slit.

  The rotation support shaft is an axis on which a truncated cone holding body fitted into one end of the support shaft rotates and supports this.

The following effects were obtained by the present invention.
By constructing a link with a joint between the rotation support shaft and the rotation arm, the axis of the roll paper and the holding body is unified without being refracted, and this is mounted on the rotation shaft. By realizing the smooth rotation of the roll paper and eliminating the idle shaft configuration that was the cause of sound generation, the generation of unpleasant noise was eliminated.

  When the roll paper is sandwiched and integrated with the truncated cone holder, the corner of the roll paper core hole and the distorted protruding part are bitten and absorbed by the buffer structure of the conical surface, thereby correcting the misalignment of the roll paper center with respect to the rotation axis. As a result, the rotation axis of the roll paper is minimized by assimilating or approaching the original axis, thereby preventing the generation of unpleasant noise caused by uneven rotation and vibration.

  Conventionally, the paper has been prevented from over-extruding by using the friction between the presser plate and roll paper from above, so the unbalanced rotation due to distortion of the roll paper causes the presser plate to directly vibrate up and down, generating noise. In the present invention, suppression of excessive paper ejection is realized by a separate configuration, and a new non-contact structure with the roll paper is realized by newly floating the presser plate constantly with the bias of the spring, and the rotational rotation To prevent the generation of unpleasant noise from the presser plate.

It is a great feature of the present invention that the roll paper can be easily attached and detached by arranging a pair of truncated cone support support links, which is an effect that was not found in conventional products. That is, when the roll paper is mounted, the roll paper end held with one hand is applied to the conical surface of the holding body from below, and the roll paper is received into the mounting space by a simple operation of pushing up, and the mounting is completed at the same time. Removal is equally easy.
This is a major feature that has not been achieved in the past because it facilitates the attachment and detachment of the roll paper while maintaining the function for preventing the generation of unpleasant noise.

Front partial sectional view showing the progress of the mounting state of the present invention The side view which shows the effect | action of the link of this invention holder Side view showing holding plate 13 of the holder of the present invention

  In the present invention, in order to realize a holder that can be pulled out silently and smoothly even with roll paper having defects such as distortion, a means for feeding out the paper by rotating the shaft is selected. Even roll paper with faults can be easily mounted on shaft rotation, and due to the above-mentioned faults, roll papers can be prevented from rotating in a non-uniform direction to prevent unpleasant noise. Examples will be described below.

  The present invention will be described with reference to the drawings. The frustoconical holding body 1 having a frustoconical shape shown in FIG. By fitting and clamping, roll paper 3 can be held and integrated without problems even if the roll paper core hole has an indefinite diameter for each manufacturer. It becomes the composition to do.

  In the above situation, the inner diameter difference between individual roll papers existing in an indeterminate form can be adjusted by the cone portion, and the inner diameter is within a certain range. If the product is a commercial product, the roll paper is naturally sandwiched at a coincidence point, and at the same time, the roll paper 3 can be mounted on the rotating shaft.

  Furthermore, the truncated cone holding body 1 constitutes a buffer structure. This is because the cone portion is made of a flexible material with respect to the end portion 2 of the roll paper core hole which is a contact point with the truncated cone holding body 1, and is entirely around. It is a structure that makes it easy to bite into the software and realizes stable integrated clamping.

This shock absorbing structure is a function that naturally corrects the bias at this time because if the roll paper core hole is distorted or there is a deformed protruding part, the frustoconical holder is biased and the roll paper is rotated. As shown in FIGS. 1 and 2, the structure of the outer peripheral surface of the cone is vertically formed with a V-shaped slit 5 having an appropriate number and depth on a conical surface made of a flexible material such as silicone rubber. By chopping and changing the surface shape, the cross-sectional shape of the buffer mountain 6 formed in the trace of the slit is thickened at the bottom with a thin triangular structure at the top or a trapezoid with an upper side, so that only at the top It is a structure in which the outer peripheral surface of the cone is changed, and the supporting force increases with the thickness as it becomes deeper as it is flexible and easily deformed. This realizes the flexibility that the space near the surface layer, that is, the slit width is wider and the flexibility is larger as the surface layer is larger.

  The action of the buffer structure shows a situation where the buffer structure part of the truncated cone holder 1 is fitted in the distorted core hole end part 2 in the sectional view taken along the line AA 'shown in FIG. The distortion part of the core hole protrudes inward, and the flexible top part of the buffer chevron 6 is bent in response to this, and the distortion part bites in by deforming and shows the state of receiving and digesting the protrusion part, and circular without other distortions In the inner periphery of the paper tube, the top of the buffer chevron 6 becomes a minimum bite and does not need to bend, but the top is supported by all remaining buffer chevron, that is, the buffer structure.

  In this way, when there are some strain protrusions, a small number of buffer ridges 6 are deformed and received and supported, and the pressure received by other buffer ridges 6 on the entire undistorted circumference is averaged by the total possession. However, the per unit is weak and stays on a small scale. As a result, the buffer structure absorbs some of the deforming protrusions, and it is easy to naturally realize the minimization of the misalignment, which is the purpose of deriving the rotational center.

  Further, the above-described action of absorbing the distortion of the core hole end portion 2 leads to a smooth shaft rotation by guiding the original core, and even if a slight misalignment remains, the initial rotation of the roll paper does not cause a load. The peripheral force acts as a so-called rocking action toward the lighter side, and becomes assimilated or approached as much as possible to the center of the truncated cone holding body 1, which serves as an anti-rotation effect of rotation and solves one problem. In particular, even a roll paper core hole having a defect such as a projecting portion absorbs this because the projecting portion penetrates deeper by the amount of the projecting portion, which acts closer to the axis and the roll paper rides on the rotating shaft.

  A rotation support shaft 4 is fitted into a shaft hole provided in the center of the truncated cone holder 1 and is supported by the shaft. The shaft tip is attached to the inner wall of the shaft hole by the force of the rotating spring 8 from the rear. With that force, the roll paper is pinched from the left and right to realize the axial support of the roll paper.

  FIG. 1 shows an embodiment in which roll paper can be easily attached and detached while maintaining the function of holding the truncated cone and the roll paper in FIG. 1. In FIG. The arm is urged inward by a rotating spring 8 that is pivotally supported by a rotating shaft 11 and is coaxially mounted. The urging force constitutes a link limited by a stopper 12. The joint 9 is effective if it can limit the rotation range such as a combination of forks and pins.

The small-diameter portion of the truncated cone holder 1 is set to correspond to the diameter when the core hole diameter of the commercially available roll paper is the minimum, and when the fitting is held near the small-diameter portion, the tilt of the rotating arm 10 is inclined inward. This inclination shown in FIG. 1 is defined as an initial inclination.
4 is changed to the other roll paper shown in FIG. 4, and the biasing force of the spring advances and fits even when the core hole diameter is sequentially increased. This means that the truncated cone holder 1 is deeply inserted into the core hole. Therefore, the rotation arm 10 is further inclined inward to reproduce the holding, and the function of absorbing and adjusting the variation of the roll paper core hole diameter is performed.

  By arranging the joint 9 in the link, even when the insertion degree of the truncated cone holding body 1 is deepened by a series of sandwiching and holding operations, the tilt of the rotating arm 10 is also deeply inclined as described above. Thus, the holding force is maintained, and it is possible to maintain unification of the three axially held central axes without being refracted.

  The inclined structure of the rotating arm described above relates to the function of the presser plate 13 in paragraph 47 described later.

  In the present invention, the unification of the shaft center is performed as a form configured with a roll paper having a paper tube shaft interposed therebetween. However, it is a great feature that the roll axis is unified at the same time when a new roll paper is loaded and that smooth rotation is naturally reproduced. This good reproducibility is directly linked to easy attachment / detachment of the roll paper.

  FIG. 3 shows the movement of the link when the roll paper is mounted. The attachment / detachment operation is performed with one hand. In FIG. 3A, when the end of the roll paper 3 is applied to the truncated cone holder 1 and pushed up from below as shown by the arrow. Rotating arm 10 is pivoted left and right to open, and roll paper can be entered as shown in FIG. 2B. Similarly, when the used roll paper tube is removed, Acts and disengages by raising the roll upward from the current state.

  When the roll paper is pushed up as described above, the conical portion reaches the core hole, and the truncated cone holding body 1 is inserted into the core hole end portion 2 by the urging force of the rotating spring 8 from the left and right to complete the installation of the roll paper. . It is possible to repetitively reproduce the loading of the roll paper on the rotating shaft, which is an unpleasant noise prevention link device, with a very high speed and simplicity. This is realized by the characteristic configuration of the present invention in which the pair is supported at two points of the rotation shafts 11a and 11b.

  Although the conventional presser plate has been a source of unpleasant noise, the present invention pays attention to this, and the presser plate 13 shown in FIG. Lifted by urging, and as shown in FIGS. 4 and 5, the roll paper is not in contact with the roll paper at all times, so that the roll paper from time to time is affected even if a small amount of deflection or partial rotation remains. Thus, a holder that does not generate unpleasant noise from the presser plate as in the prior art is realized. If the board is pressed by hand only when necessary, the board stops the roll paper so that the paper can be cut out.

  4 and 5, if the presser plate 13 is pressed by hand when cutting the paper, the presser force is transmitted from the roll paper to the truncated cone holder and further to the rotating arm. The applied pressure stops at the rotating shaft 11, but at this time the rotating arm is inclined at least initially inward, so that the truncated cone holding body compresses from left to right as the escape destination, A pressing force is applied to the fitting portion of the buffer structure to strengthen the clamping force. This structure acts as an effect that stabilizes and strengthens the roll paper integrated holding force as an action that occurs every time paper is cut.

  By using the back surface 15 of the truncated cone holder as a friction surface, the friction disk 16 is brought into contact with the friction spring 17 so that the integrated roll paper has a certain pulling resistance due to friction. It is a configuration that suppresses excessive paper in place of a board. This overshoot suppression device is installed on at least one of the left and right sides.

  As for the structure that suppresses excessive paper output, the indirect resistance, which is an example shown in the present invention, is preferable from the viewpoint of noise prevention, as compared with the conventional direct resistance of roll paper by a pressing plate. Moreover, it is good also considering a rotation spindle as a resistor.
