Description

  The present invention relates to a roll paper holder that can very easily discharge a core tube of used roll paper and supply new roll paper into the holder.

  Conventionally, in a general household, when replacing the roll paper of the roll paper holder with a new roll paper, firstly, one spare roll paper is prepared, and then the core tube of the used roll paper is used as the roll paper holder. Remove the mandrel from the removed core tube, attach the removed mandrel to the core tube of a new spare roll paper, and set the roll paper with the core tube attached to the roll paper holder to replace the roll paper. Was finished. In addition, there are two types of roll paper (toilet paper) that have been perforated and those that have not been perforated. When using toilet paper with perforations, There are two methods of use: a method of breaking from the perforation, and a method of cutting with the tip of the roll paper cover as a cutting edge. When it breaks using a perforation, it can be ruptured cleanly from the perforation, but when it is cut with the tip of the cover as the cutting edge, it sometimes cuts obliquely and remains unsightly.

JP 7-275161 A Japanese Patent Laid-Open No. 5-80395

By the way, when replacing roll paper (toilet paper), first prepare spare roll paper, then remove the used roll paper core tube from the roll paper holder, remove the mandrel from the removed core tube, and remove the mandrel Is attached to the core tube of the preliminary roll paper, and the roll paper attached with the mandrel is set in the roll paper holder. However, even this replacement work, which takes only a short time, feels long when you are in a hurry, notices that there is no paper left on the roll paper after sitting on the toilet seat, and the spare roll paper to be prepared is also within easy reach When I find out, I sometimes even get into a small panic.
Moreover, regarding the usage of the roll paper cover of the roll paper holder that is currently on the market, it is convenient because it can be used in two ways: breaking and cutting. On the other hand, as a result of using the method of cutting, if the cutting is too fine, the cut of the paper is hidden in the roll paper cover, and there is an effort to search for the cut when it is used next time. On the other hand, if the cutting is poor, it will tear off at an angle and will be unsightly, giving the user an unpleasant feeling.

  On the other hand, as a technique related to the roll paper holder, the roll paper holder described in Patent Documents 1 and 2 is known. Each of these roll paper holders has a preliminary storage chamber for storing spare roll paper in the upper part of the main body case, and has a holding member for hollowly holding the preliminary roll paper in the lower part of the preliminary roll storage chamber. Below the member, it has a pair of receiving rollers in a parallel arrangement for holding the roll paper to be used. And the space | interval between a pair of receiving rollers is set to the dimension which can let the core pipe which was consumed after all the paper was consumed. The interval between the receiving rollers is set to a size as close as possible to the outer diameter of the core tube so that all the paper can be used up without waste.

  By the way, a general core tube is often distorted or greatly deformed. When the core tube is distorted or greatly deformed in this way, the core tube passes through the gap between the receiving rollers set to a size close to the outer diameter of the core tube as in Patent Documents 1 and 2. There are cases where it cannot be done. If the core tube is clogged in the main body case in this way, the next preliminary roll paper may not be replenished to the specified position. In addition, when the preliminary roll paper in the preliminary roll storage chamber is held hollow by a relatively sharp holding member, the preliminary roll paper cannot be dropped onto the pair of receiving rollers due to being caught by the holding member, and the roll can be rolled in the main body case. There is also a risk of clogging.

  The present invention has been made in order to eliminate the above-described problems, and it is possible to discharge a core tube of used roll paper in the holder and supply new roll paper into the holder by operating the handle. The first object of the present invention is to provide a roll paper holder which can be very easily performed by rotating the integral rotating body once. A second object of the present invention is to provide a roll paper holder having a roll paper cover dedicated to breakage that can be beautifully broken from the perforation when the tip of the roll paper cover is used as a cutting edge.

  In order to solve the above-described problems, a roll paper holder according to the present invention is placed between a pair of side plate portions spaced apart from each other on the left and right sides and upper portions of the left and right side plate portions, and a spare roll paper is placed thereon. And a pair of side plate portions fixed to a wall or the like and rotatably supported about a pair of side plate portions around a horizontal axis, and a pair of side plate portions. A hollow shaft tray for receiving and rotating a roll paper mandrel inserted into the roll paper core tube at the roll paper use position, and both ends of the roll paper core supported by the hollow shaft tray The discharge groove portion formed in the pair of side plate portions so as to be discharged from the hollow shaft tray portion with the rotation of the side plate portion, and the roll core of the roll paper of the spare roll paper, which are respectively erected on the holder column bearing portion A pair of side plates on each end Roll paper guide rails for guiding the outer peripheral edge of the paper sheet and both ends of the roll paper core rod guided to the outer peripheral edge of the pair of side plate portions from the outer peripheral edge toward the hollow shaft tray portion as the side plate portion rotates. And an inlet groove formed in the side plate so as to be guided.

  Further, in the above configuration, the hollow shaft tray portion is formed in a semi-cylindrical shape having an upper surface opened, and when the placement plate portion is located directly above, the hollow shaft tray portion is hollow as viewed from the side surface in which the paper take-out direction is rightward. The opening part of the upper surface of the shaft tray part is arranged in the upper left direction.

  And in each above-mentioned structure, the upper part of the guide rail for roll paper is bent and formed toward the attachment wall side to which a holder support | pillar bearing part is attached.

  Furthermore, in each of the above-described configurations, a roll paper cover dedicated to breakage is formed in which a front end portion for pressing the roll paper is formed in a round shape when viewed from the side, and end portions are pivotally supported by a pair of side plate portions. . In general, there are a cutting method that uses the tip of the roll paper cover as a blade and a breaking method that uses a perforation, but this configuration cannot be cut by having a round part at the tip of the roll paper cover of the holder. In this way, the breakage is made using only the perforations.

  According to the roll paper holder according to the present invention, when the roll paper used in the hollow shaft tray part is lost, the user rotates the side plate part, and the roll paper mandrel of the used roll paper is removed. It can be automatically detached from the hollow shaft tray by the action of the discharge groove. Thereafter, when the side plate portion is further rotated, the roll paper mandrel of the preliminary roll paper can be guided and received by the hollow shaft tray portion by the action of the inlet groove portion. That is, it is very easy to discharge the roll paper core tube used in the hollow shaft tray portion in the holder and supply new roll paper to the hollow shaft tray portion by rotating the side plate portion, for example, once. You can do it.

  In addition, the hollow shaft tray portion is formed in a semi-cylindrical shape with an open top surface, and when the placement plate portion is positioned directly above, the paper take-out direction is viewed from the side facing rightward, and the hollow shaft tray portion is In the case where the upper surface opening portion is arranged in the upper left direction, the roll paper mandrel can be easily detached from the hollow shaft saucer portion with a slight rotation of the hollow shaft saucer portion, and further when receiving the preliminary roll paper Can be reliably received from the inlet groove portion to the hollow shaft tray portion without delay.

  When the upper part of the roll paper guide rail is bent toward the attachment wall side, the design beauty is viewed from the side, and a space can be secured above the front part of the roll paper holder. Therefore, a compact and beautiful roll paper holder can be provided without taking extra space in a relatively narrow toilet space.

  Further, in a roll paper holder having a roll paper cover with the paper cover tip formed as a round part, the perforation appeared from the roll paper cover when the first person using the roll paper finishes pulling out the required length. Further, after about 2 to 3 centimeters of extra pulling, when pulled lightly in the pulling direction, it can be broken cleanly along the perforation line. The next user can grasp and pull the roll paper that protrudes 2 to 3 cm from the roll paper cover. This can be used in the same way up to the person who finishes using the roll paper at the end without changing even if the user changes.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The embodiment described below is merely an example embodying the present invention, and does not limit the technical scope of the present invention. FIG. 1 is a side view showing a roll paper holder and a roll paper attached to the roll paper holder according to an embodiment of the present invention, FIG. 2 is a front view of the roll paper holder and the roll paper, and FIG. FIG. 2 is a cross-sectional view taken along line AA in FIG.
In each of the drawings, a roll paper holder 1 according to this embodiment is fixed to a pair of side plates 5 having a pair of side plate portions 5A and 5A that are spaced apart from each other with the plate plane in a vertical direction, and a toilet mounting wall W, for example. Holder post body 2, left and right holder post bearing portions 2 a and 2 a provided on the holder post body 2 and pivotally supporting the pair of side plates 5 around a horizontal axis C, and horizontally arranged The roll paper mandrel R3 inserted through the roll paper core tube R2 of the roll paper R is used at the roll paper use position (position where the axis of the roll paper mandrel R3 on both the left and right sides substantially coincides with the axis C in the figure). The hollow shaft tray 8 that receives and rotatably supports the hollow shaft tray R2 and the both ends of the roll paper mandrel R3 that is erected on the left and right holder column bearings 2a and 2a and inserted into the preliminary roll paper R1 are hollow. Shaft tray 8 Right and left two pairs of roll paper guide rails 4, 4, 4 and 4 for guiding towards, and a handle 11 for manually rotating the integral rotor 3,. Then, a roll paper cover 7 and a pivot shaft 9, a stopper pin 10, and a hollow shaft receiving tray portion 8 which will be described in detail later are combined with the pair of side plates 5 to form a single body (see FIG. 4). ) Is the integral rotating body 3.

  Then, the two side plate portions 5A and 5A of the pair of side plates 5 are arranged facing each other with an interval of 120 mm on the left and right sides in consideration of the lateral width of the roll paper R and the breaking roll paper cover 7 accommodated between the side plate portions 5A and 5A. Has been. 1 indicates the roll paper core of the preliminary roll paper R1 when the preliminary roll paper R1 is placed on the placement plate portion 5Ab at the position (home position) shown in FIGS. The axial center position which corresponds to the both ends of the roll paper mandrel R3 inserted through the tube R2 is shown. Then, a roll paper mandrel R3 for the preliminary roll paper R1 lowered to the outer peripheral surface of the pair of side plates 5 is a 16 mmφ hole (a hole connected to the hollow shaft tray portion 8) that is bored at the center of each side plate portion 5A. An inlet groove M1 (FIG. 12 (b)) which is a groove carved from the outer peripheral surface of each side plate portion 5A toward the central hole 13 so that it can be guided to the central hole 13), and a roll of roll paper R The paper core tube R2 and the discharge groove portion M2 for simultaneously discharging the roll paper mandrel R3 inserted through the roll paper core tube R2 are formed in the side plate portions 5A and 5A of the pair of side plates 5.

  Here, the procedure for producing the side plate portion 5A and the protruding surface extending radially outward therefrom will be described. First, a straight line (HH line) is drawn vertically on a flat plate for producing the side plate portion 5A (FIG. 12A), and a circle having a radius of 62 mm centered on a point C on the line is drawn. A line with an angle of 15 degrees is stretched from the center C of the center in two directions on the left and right, and marks a and b are marked at the intersections with the circumference. Similarly, a circle with a radius of 50 mm is drawn from the axis C. Similarly to the above, a line with an angle of 20 degrees is extended from the axis C in two directions on the left and right, and marks c and d are marked at intersections with the circumference of the radius 50 mm. For example, if the mark attached to this intersection is connected clockwise to marks a, b, d, and c, and if this line is cut through, the height 12 mm (axial center C The side plate portion 5A having a projection surface with a radius of 62 mm from the side plate 5A can be created. The two side plate portions 5A and 5A with the above-mentioned protruding surfaces facing upward are spaced apart from each other, and a curved mounting plate portion 5Ab having a curvature of 62R is integrated between the protruding surfaces of the two side plate portions 5A and 5A. As a result, the pair of side plates 5 is formed. The placing plate portion 5Ab is configured to place the preliminary roll paper R1 on the upper surface thereof. In this case, the dimension of the height of 12 mm of the protruding surface of each side plate portion 5A is such that the bottom surface of the preliminary roll paper R1 placed on the placement plate portion 5Ab and the take-out position arranged at the use position in the side plate portion 5A are used. A distance from the uppermost surface of the roll paper R is maintained to facilitate removal of the paper P from the roll paper R.

  Further, the hollow shaft tray portion 8 is formed in a semi-cylindrical shape having an outer diameter of 22 mmφ, an inner diameter of 16 mmφ, a semicylindrical portion length of 20 mm, and a bottom thickness portion width of 10 mm, for example. The hollow shaft tray portion 8 is provided in such a manner that the center of the semicircular portion side is aligned with the axis C of the center hole 13 of the pair of side plate portions 5A and 5A. A portion having a bottom thickness portion width of 10 mm and an outer diameter of 22 mmφ is pivotally supported in the bearing hole of the holder column bearing portion 2a. Engagement projections 12 and 12 for attaching the handle 11 protrude from both side end surfaces of the hollow shaft tray 8.

  As shown in FIGS. 4 and 8, the breaking roll paper cover 7 is supported on the pivot shaft 9 that is horizontally mounted between the front upper ends of the protrusions of the side plates 5A and 5A of the pair of side plates 5 so as to be swingable up and down. Has been. In addition, a stopper pin 10 is horizontally mounted between the projecting surfaces of the side plate portions 5A and 5A at a position below the pivot shaft 9. After the used roll paper R has been used up, the stopper pin 10 makes the breaking roll paper cover 7 come into contact with the stopper pin 10 so that the breaking roll paper cover 7 is located above the position in contact with the remaining roll paper core tube R2. It is designed to prevent rotation.

  As shown in FIGS. 5 (a) and 5 (b), each of the holder support bodies 2 described above is provided at the base portion screwed to the mounting wall W and at the arm tip of the base portion, respectively. It is comprised from the holder support | pillar bearing part 2a which has the bearing hole which has the center axis common with the center C. Further, as shown in FIGS. 5C and 5D, a pair of roll paper guide rails 4 and 4 that are separated from each other are erected upward on the upper surface of each holder column bearing portion 2 a. . Between the pair of roll paper guide rails 4, 4, there is a guide rail guide path 4a that guides the roll paper mandrel R3 into the bearing hole of each holder column bearing portion 2a. Each roll paper guide rail 4 is reinforced by ribs provided side by side and at the base. And the bearing guide inlet 2aa which connects the guide path 4a in a guide rail and a bearing hole is formed in the upper part of each support | pillar bearing part 2a, and a bearing hole and a downward exterior are connected to the lower part of each support | pillar bearing part 2a. A bearing guide outlet 2ab for discharge is formed.

  As shown in FIGS. 6A and 6B, the handle 11 is formed in an annular shape having a handle fitting portion 11a having a square cross section, for example. The handle 11 is prevented from rotating by the engagement protrusion 12 of the hollow shaft receiving portion 8 being inserted into the handle fitting portion 11a. Further, as shown in FIGS. 6C and 6D, the roll paper mandrel R3 includes an insertion portion to be inserted into the roll paper core tube R2 of the roll paper R and R1, and the insertion portion. And projecting portions that are integrally formed so as to project in the axial direction from both end faces.

  And each hollow shaft saucer part 8 mentioned above is formed in the semicylindrical shape seeing from the side, and also has the upper surface opening part 14, as shown also in FIG. The upper surface opening 14 of each hollow shaft tray portion 8 is viewed from the side surface in which the paper take-out direction is rightward when the placement plate portion 5Ab of the pair of side plates 5 is positioned directly above (see FIG. 7C). The upper surface opening 14 is arranged so as to face the upper left. The inner curved surface of each hollow shaft receiving portion 8 serves as a core receiving portion for receiving the roll paper mandrel R3 guided through the guide rail guide path 4a and the bearing guide inlet 2aa. As described above, when the mounting plate portion 5Ab is located directly above, the upper surface opening 14 of each hollow shaft receiving portion 8 has a horizontal line (one-dot chain line g) connecting the two semicircular end surfaces 15A and 15B. It is arranged so as to be inclined at an inclination angle θ of about 45 degrees with respect to a one-dot chain line h parallel to the direction. That is, in the upper surface opening 14 at this time, the downstream (rear) semicircular end surface 15A in the rotation direction (arrow D direction) of the integral rotating unit 3 is lower than the upstream (front) semicircular end surface 15B. So that it is tilted.

  In the above-mentioned roll paper R, there are two types of products that are lined up in stores for general household use, a single type of single paper roll and a double type of double roll of paper, both of which are about 114 mm wide, The double-type paper length for one roll is about one-half that of the single type, and the perforations are processed so that both rolls are easy to break during use. The interval between the perforations is 228 mm in the longitudinal direction for the single type and 114 mm for the double type, so that the single type has a rectangular break paper of 114 mm × 228 mm, and the double type has a square break paper of 114 mm × 114 mm, respectively. One roll of roll paper is formed continuously.

  Since the roll paper cover 7 for breaking the roll paper holder 1 has the round portion 7a at the tip of the cover, it cannot take a cutting method that looks like a cutting edge. That is, as a method of using the breaking roll paper cover 7, pay attention to the perforation drawn from the breaking roll paper cover 7 when drawing out the required length of paper P from the roll paper R, and the round end of the cover When the paper P is pulled out so that a perforation of about 2 to 3 centimeters comes out from the portion 7a, the paper roll P can be easily broken along the perforation by pressing the roll paper cover 7 for breaking and pulling the paper P lightly in the pulling direction. . After use, since the paper P of 2 to 3 cm always remains at the tip of the roll paper cover 7 for breaking, the user can easily pick and use the roll paper P remaining 2 to 3 cm in advance. it can. This usage method can be used in the same way even if the user changes each time until one roll of roll paper R is used up.

  By the way, when the handle 11 is rotated once, the integral rotator 3 also rotates once at the same angle. The movement of each part accompanying the rotation, for example, the position and descending distance of the auxiliary roll paper R1, the pair of side plates 5A. , 5A with respect to the remaining distance to the center hole 13, the change in the inclination angle θ of the upper surface opening 14 of the hollow shaft tray portion 8, the rotational operation of the roll paper cover 7 for breaking, the posture of the inlet groove M1, etc. 36 modes were examined in increments of 10 degrees for one rotation (360 degrees). These contents are shown in FIG. In addition, 10 aspects are selected from the 36 aspects of FIG. 9 and made into drawings (FIGS. 10A to 10J), and each aspect will be described below with reference to these drawings.

“FIG. 10 branch diagram number (a): description of rotation angle α = 0 degrees of integral rotating body 3”
Even after the use of the roll paper R in use, the preliminary roll paper R1 is still placed on the placement plate portion 5Ab and in a storage state. Further, both end portions of the roll paper mandrel R3 inserted through the roll paper R are still received by the hollow shaft tray portion 8. Therefore, the core tube R2 of the roll paper R and the roll paper mandrel R3 are discharged from the hollow shaft tray part 8, and the roll paper mandrel R3 of the preparatory roll paper R1 is moved to the hollow shaft tray part 8 to thereby remove the spare roll paper R1. The roll paper R is provided for use. FIG. 10A shows a state immediately before the user rotates the manual handle 11 once in the arrow D direction.

[FIG. 10 branch diagram number (b): explanation of rotation angle α = 30 degrees]
FIG. 10B shows that when the rotation angle of the integral rotating body 3 is 30 degrees, the placing plate portion 5Ab is also rotating, and the outer peripheral lower surface of the roll paper R1 placed on the upper surface of the placing plate portion 5Ab is the placing plate. A state is shown in which the side surface of the part 5Ab rolls down and moves to the upper surface of the breaking roll paper cover 7.

[FIG. 10 branch figure number (c): explanation of rotation angle α = 130 degrees]
When the rotation angle is 130 degrees, the inclination angle of the semi-cylindrical opening surface of the hollow shaft tray 8 is 85 degrees to the left and is almost directly below. (The roll paper mandrel R3 inserted into the roll paper core tube R2 by the inclination direction and the inclination angle θ of the upper surface opening 14 of the hollow shaft tray 8 shown in FIG. 9 together with the roll paper core tube R2 is the discharge groove M2 Accordingly, the breaking roll paper cover 7 supported by the roll paper core tube R2 loses its support and tries to rotate clockwise in FIG. However, it is in contact with and supported by the stopper pin 10 and maintains the conventional posture.

[FIG. 10 branch diagram number (d): description of rotation angle α = 160 degrees] and [FIG. 10 branch diagram number (e): description of rotation angle α = 170 degrees]
When the rotation angle is 160 degrees, the outer peripheral surface of the roll paper mandrel R3 (10 mmφ) inserted through the descending preliminary roll paper R1 is substantially in contact with the pair of side plates 5. Further, it can be seen that it advances 10 degrees and bites 2 mm at 170 degrees. In order to eliminate the biting state, the depth of the outer peripheral surface of the pair of side plates 5 at the angle of 180 degrees (branch number (f)) from the contact point of the outer surface of the pair of side plates 5 when rotated 160 degrees is gently A simple slope groove is formed to avoid contact with the pair of side plates 5. The slope groove serves as a guide path through which the roll paper mandrel R3 can easily enter the inlet groove M1 described later.

[FIG. 10 branch figure number (i): explanation of rotation angle α = 290 degrees]
In explaining the rotation angle α = 180 degrees, it is necessary to clear the problem at 290 degrees even at 180 degrees, so the explanation will be given later, but the state at the rotation angle α = 290 degrees will be described first. explain.
FIG. 11A shows the position of the placement plate portion 5Ab when the rotation angle α has advanced to 290 degrees, and the outer peripheral surface of the descending preliminary roll paper R1 is the side surface Q2 of the placement plate portion 5Ab. It is the figure which touches (refer Fig.11 (a)). The figure clearly shows that the distances y1 to y2 on the horizontal line drawn from the vertical axis xx passing through the roll paper mandrel R3 to the point Q become smaller as the rotation angle advances from 270 degrees. The problem is that the roll paper mandrel R3 inserted into the preparatory roll paper R1 is received by the center hole 13 (16 mmφ) and the hollow shaft tray 8 to receive the roll paper mandrel inserted into the descending preparatory roll paper R1. This indicates that R3 must be received and placed when rotating 270 degrees. For comparison, FIGS. 11B to 11D are sectional views showing the state in the vicinity of the hollow shaft tray portion 8 when the rotation angle α is 0 degrees (360 degrees).

[FIG. 10 branch figure number (f): explanation of rotation angle α = 180 degrees]
Returning to the previous state, when the rotation angle α reaches 180 degrees, the cover surface of the breaking roll paper cover 7 is inverted as shown by the arrow E and hangs downward. Due to this influence, the preliminary roll paper R1 supporting the upper surface of the breaking roll paper cover 7 becomes free to move downward. An approach for receiving the roll paper mandrel R3 of the roll paper R1 in which the downward movement is free in the center hole 13 and the hollow shaft tray 8 when the rotation angle α reaches 270 °. A production mode of the entrance groove part M1 which is a path will be described with reference to FIG. Here, 180 degrees to 270 degrees centered on the axis C of the side plate portion 5A is divided into 9 parts in 10 degree increments, and 10 lines in 10 degree increments along the 9 divisions are provided between 180 degrees and 270 degrees. Stretch the line. Next, the lowering distance 50 mm from the outer peripheral surface of the side plate portion 5A to the axis C of the side plate portion 5 is divided by 9, and this value is set as the lowering distance for every 10 degrees of the spare roll paper R1 (= roll paper mandrel R3). A value at each angle is assigned and marked, a hole of 10 mmφ is bored in the marked mark, and a locus line connecting the holes is defined as an inlet groove portion M1. Further, in FIG. 12B, a push pin is hit on the center axis C of the side plate portion 5A, and the stretched line of 10 degrees is regarded as a vertical line. When rotating in the direction D, the position of the roll paper mandrel R3 that is descending with each angle as a vertical line and the state of being vertically lowered and received by the center hole 13 and the hollow shaft tray 8 are also visually observed. Can be confirmed.

  Further, when the inlet groove portion M1 and the discharge groove portion M2 are cut into the side plate portion 5A, a portion surrounded by the inlet groove portion M1 and the discharge groove portion M2 falls off from the pair of side plates 5 (see FIG. 12). This makes it seem that the movement of the roll paper mandrel R3 inserted into the roll paper R in the pair of side plates 5 is free at first glance, but the guides in the roll paper lowering guide rails 4 and 4 are free. The roll paper mandrel R3 that is descending the path 4a is limited in movement other than the downward direction due to the shape effect of the guide path 4a, and descends only toward the center hole 13 and the hollow shaft tray part 8. .

[FIG. 10 branch diagram number (h): description of rotation angle α = 270 degrees] and [FIG. 10 branch diagram number (j): description of rotation angle α = 360 degrees]
When the roll paper R is received by the central hole 13 and the hollow shaft tray 8 at a rotation angle α = 270 degrees, the inclination angle θ of the hollow shaft tray 8 is 45 degrees upward (see FIG. 9). Further, at the time of α = 360 degrees when the rotation of the hollow shaft tray portion 8 has advanced 90 degrees, the inclination angle θ of the upper surface opening 14 of the hollow shaft tray section 8 indicates 45 degrees upward to the left, The rotation (360 degree rotation) ends. The breaking roll paper cover 7 also completely covers the outermost peripheral surface of the paper P of the roll paper R, and the paper breaking preparation is completed.

  As described above, in the state where the integral rotating body 3 is stationary at the rotation angle α = 0 ° (360 °), the inclination angle θ of the upper surface opening 14 of the hollow shaft tray portion 8 is arranged at 45 degrees upward to the left. When the handle 11 is rotated once in order to use the preparatory roll paper R1 as the take-out roll paper R, the upper surface opening of the hollow shaft tray 8 when the rotation angle α of the pair of side plates 5 first advances to 130 degrees. The inclination angle θ of the portion 14 is 85 degrees downward to the left and almost directly below. Thus, both the roll paper mandrel R3 and the core tube R2 of the roll paper R received by the hollow shaft tray 8 can be discharged. When the rotation angle α of the pair of side plates 5 further advances to 180 degrees, the roll paper mandrel R3 inserted through the core tube R2 is used for the preliminary roll paper R1 that is descending in the guide path 4a of the roll paper guide rail 4. It contacts the outer peripheral surface of the pair of side plates 5 and reaches the inlet groove M1. When the rotation angle α advances to 270 degrees while the roll paper mandrel R3 is guided by the inlet groove M1, the roll paper mandrel R3 is placed in the center hole 13 and the hollow shaft tray 8 located at the center of the pair of side plates 5. It will fit.

At this time, the difference between the outer diameter 10 mmφ of the roll paper mandrel R3 and the inner diameter 16 mmφ of the center hole 13 of the side plate portion 5A, while the inclination angle θ of the upper surface opening 14 of the hollow shaft receiving portion 8 is 45 degrees upward. By setting the length to 6 mm, the roll paper mandrel R3 can be received in the center hole 13 and the hollow shaft tray 8 with a space.
When the rotation further proceeds and the rotation angle α reaches 360 degrees and the rotation is stopped, the inclination angle θ of the upper surface opening 14 of the hollow shaft tray portion 8 becomes 45 degrees upward to the left, and the roll paper R can be taken out. . On the other hand, when pulling out the paper P of the roll paper R, the roll paper R and the roll paper mandrel R3 also receive a force to move in the take-out direction, but the inclination direction of the upper surface opening 14 of the hollow shaft tray part 8 is leftward. Therefore, the roll paper mandrel R3 can be stably held in the hollow shaft tray 8. A number of such actions due to the inclination of the upper surface opening 14 of the hollow shaft receiving part 8 during one rotation of the handle 11 can be expressed as “characteristic inclined arrangement of the hollow shaft receiving part 8”.

  That is, the roll paper mandrel R3 extracted from the core roll R2 of the used used roll paper R is mounted on the roll paper core pipe R2 to be reused as a new preliminary roll paper R1. Then, by inserting both ends of the loaded roll paper mandrel R3 into the guide path 4a of the roll paper guide rail 4 and placing the roll paper on the placing plate portion 5Ab, a new preliminary roll paper R1 is obtained. When the preliminary roll paper R1 is used as the roll paper R to be used, the user can change the roll paper (toilet paper) to be used by rotating the handle 11 only once even when the user is seated on the toilet seat. Can be done.

  Incidentally, the rotation angle α (= 0 degrees (360 degrees), 90 degrees, 180 degrees, 270 degrees) of the side plate portion 5A of the integral rotating body 3 when the integral rotating body 3 rotates, and the roll paper cover 7 for breaking. The relationship with the swinging motion is as shown in FIG.

Further, the roll paper mandrel R3 of the preliminary roll paper R1 that has been placed on the placing plate portion 5Ab of the integral rotating body 3 descends with the rotation of the integral rotating body 3, and the inlet groove portion of the placing plate portion 5A. A model guided by M1 into the center hole 13 and further from the upper surface opening 14 to the center of the hollow shaft tray 8 is as shown in FIG.
In FIG. 14, the rotation angle α = 0 to 270 degrees during one rotation of the integral rotating body 3 is divided into 27 equal parts every 10 degrees, and 27 roll paper mandrels R3 are drawn for each angle. . The positions of the displayed roll paper mandrels R3 are drawn so as to move in the direction (clockwise) opposite to the actual rotation of the integral rotor 3 around the axis C. Here, a vertical line connecting the axis C1 and the axis C is set to 0 degree, and a clockwise angle about the axis C from the vertical line is set as a rotation angle of the integral rotating body 3, and each displayed roll paper The linear distance between the bouncer R3 and the axis C is the descending distance of the preliminary roll paper R1. Each distance corresponding to each angle α, θ is shown in detail in the table of FIG.
Also from FIG. 14, the roll paper mandrel R3 of the preliminary roll paper R1 is smoothly and gradually descending, and the end plate is guided by the inlet groove portion M1 and surely fits in the center hole 13 and the hollow shaft tray portion 8. I understand.

  In the above-described embodiment, the example using the roll paper guide rail 4 extending linearly in the vertical direction is shown, but the present invention is not limited thereto. For example, a roll paper holder 1a as shown in FIG. 15 is also included in the present invention. In this roll paper holder 1a, the upper part of the guide path 4aB of the pair of left and right roll paper guide rails 4B, 4B, 4B, 4B is directed to the opposite side (rear direction) of the paper take-out direction (front direction). It is formed to bend toward the attachment wall W side of the body 2. The roll paper holder 1a is also provided with a decorative board 33 that covers the side periphery of the preliminary roll paper R1. The decorative plate 33 is formed in a rectangular tube-like body that is open at the top and bottom, and the opening on the top surface is an inlet 34 for loading the preliminary roll paper R1. However, an openable / closable lid (not shown) may be attached to the loading port 34 to stop the lid.

  According to the roll paper holder 1a described above, the roll paper guide rails 4B, 4B, 4B, 4B are formed to be bent to the mounting wall W side (the rear side of the holder). In addition, a space can be secured in front of the upper portion of the roll paper holder 1a. Therefore, a compact and beautiful roll paper holder 1a can be provided without taking extra space in a relatively narrow toilet space. Further, since the decorative sheet 33 covering the periphery of the roll paper guide rails 4B, 4B, 4B, 4B and the spare roll paper R1 is provided, the flying dust and liquid can be applied to the spare roll paper R1 without damaging the appearance. It can be prevented from adhering and is hygienic.

In the above description, the roll paper guide rails that are paired in front and rear are illustrated as being parallel to each other, but the present invention is not limited thereto. For example, a roll paper holder 1b as shown in FIG. 16 is also included in the present invention. The roll paper holder 1b is structurally different from the roll paper holder 1a (FIG. 15) in that the rear roll paper guide rail 4B is common and the upper end 4Bb of the front roll paper guide rail 4Ba faces forward. It is formed by being refracted in the (paper removal direction).
According to the roll paper holder 1b, the upper end portion 4Bb of the roll paper guide rail 4Ba is refracted forward, so that the preliminary roll paper can be replenished horizontally rearward from the front side of the roll paper holder 1b. . This eliminates the need for a roll paper replenishment space above the roll paper holder 1b. As a result, the cabinet 35 including the vertical plate portion 35A attached to the attachment wall W and the horizontal plate portion 35B formed to extend forward from the upper side of the vertical plate portion 35A can be used. Accordingly, the upper surface of the horizontal plate portion 35B can be used as a storage space for another roll paper or equipment, and dust accumulation on the preliminary roll paper stored between the roll paper guide rails 4B and 4Ba can be suppressed.

The roll paper used for the roll paper holder of the present invention may be roll paper Ra or spare roll paper R1a in use as shown in FIG. In these roll papers Ra and R1a, the roll paper core tube R2a is formed with a considerably larger diameter than the roll paper core tube R2 as compared with the general roll papers R and R1 described above. The insertion portion of the roll paper mandrel R3a to be inserted into the roll paper core tube R2a is also formed with a large diameter. The paper P wound around the roll paper core tube R2a is suitable for high-end hotels and department stores because it is close to a new article with a large outer diameter even before it is used up and is not sneaky. Incidentally, in luxury hotels, department stores, etc., when the paper P used by the customer is somewhat reduced, the roll paper R is replaced with a new spare roll paper R1 in order to avoid a feeling of mid-use. The replaced roll paper R in use is actually used by employees, taken for employees, or discarded.
On the other hand, the roll paper Ra, R1a has a small customer usable amount and the outer diameter of the paper P does not become so small even when used. As a result, there is no problem that the paper P can be replaced although there is a large amount of paper remaining, and the waste of the paper P can be reduced to the maximum.

  Furthermore, in the above, the roll paper R, R1 having the roll paper core tube R2 is illustrated, and the example in which the roll paper mandrel R3 is inserted into the roll paper core tube R2 is shown, but the present invention is not limited thereto. . For example, a roll paper core tube R2 that does not have the roll paper core tube R2 is replaced with a roll paper core tube R2, and a roll paper mandrel R3 is inserted into the hollow core tube and used. included.

  Moreover, although the toilet paper roll was mentioned as an example as roll paper in the above, the roll paper of this invention is not limited to it. For example, it is needless to say that the present invention can also be applied as a holder that accommodates a roll film or roll sheet formed by winding medical roll paper, cooking roll paper, industrial roll paper, or a synthetic resin film or sheet.

  In the above description, the example in which the roll paper holders 1, 1 a, 1 b are attached to the left side wall in a posture in which the toilet user is seated on the toilet seat is described. When these holders are attached, they can be used in the same manner as the left side attachment. At that time, it is necessary to replace the handle 11 that has been attached to the engagement projection 12 on the one end side with the engagement projection 12 on the other end side, and the handle 11 is rotated counterclockwise. To right rotation.

  It should be noted that the present invention is not limited to the above-described embodiment, and includes various modifications and corrections that can be conceived as long as they have ordinary knowledge in the field of the present invention, and the gist of the present invention. Those subjected to design changes within a range that does not deviate are also included in the present invention.
