Description

  The present invention relates to a roll paper holder for placing roll paper wound in a roll shape, and cutting a paper drawn out by an arbitrary amount therefrom. For example, the roll paper holder is attached to a wall surface of a toilet space. The present invention relates to a roll paper holder that can be used to hold and cut roll paper.

  For example, the most widely used roll paper currently used in toilets as roll paper is currently supported by the roll core so that it can rotate and can swing on the upper surface of the roll paper. This is a type in which the paper is cut by cutting teeth provided at the tip of the paper cutting plate in contact. In the type that supports the roll core in a rotatable manner, in order to improve the cutting performance by increasing the contact weight with the roll paper by increasing the weight of the paper cutting board or pressing the paper cutting board on the roll paper with a spring. However, since the paper cutting board has a structure that can be pressed against the roll paper, it will contact the roll paper not only when cutting but also when it is pulled out, so increase the pressing force when cutting As a result, the resistance at the time of pulling out increased, the paper was torn, and the pulling out performance deteriorated, and it was difficult to achieve both cutting performance and pulling out performance.

  In view of this, a roll paper holder has been proposed that has a configuration in which roll paper is placed and separates a placement portion that comes into contact with the roll paper when pulled out and a cutting portion that comes into contact with when cutting. (See Patent Document 1 and Patent Document 2)

The roll paper holders described in these prior patent documents are formed with a drawer outlet for pulling out paper on the bottom surface of the placement portion on which the roll is placed, and the paper is drawn out from there to the front of the placement portion. It is configured to cut the paper with the provided cutting teeth, and it is easy to achieve both cutting performance and drawing performance, and the paper remaining between the drawing outlet and cutting teeth becomes the picking allowance at the next drawing, making it easy to use Is a good one.
However, in the conventional placement type roll paper holder described in Patent Document 1 and Patent Document 2, the sliding resistance is high in order to prevent the movement when the paper is pressed against the cutting tooth in the vicinity of the cutting tooth. There is a contact surface, but the contact surface is flat, so the paper sticks to the contact surface, and the next time you pull out the paper, it takes time to peel it off. was there.

Japanese Patent Laid-Open No. 9-28615 (see FIGS. 3 and 4) JP 2006-75567 A

  The present invention has been made in order to solve the above-described problem. When the paper is cut, the paper does not stick to the contact surface in the vicinity of the cutting teeth, and the end of the paper can be easily picked when the paper is pulled out next time. The purpose is to provide a roll paper holder.

  Hereinafter, a first embodiment of a roll paper holder in the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a roll paper holder 1 according to a first embodiment of the present invention. The roll paper 2 is used by being placed on a box-shaped roll paper holder 1 whose upper surface is opened with the axis of the roll paper 2 lying sideways.

  FIG. 2 is a diagram illustrating a state in which the roll paper 2 is removed from FIG. 1. An upper surface of the roll paper holder 1 serves as a placement portion 3 for placing the roll paper 2. The mounting portion 3 has a fixed portion 4 fixed along the toilet wall surface W, a descending portion 5 inclined downward from the fixed portion 4, and an upward inclined from the front of the descending portion 5 to the near side. This is a space surrounded by the rising portion 6, the side wall portions 7 formed on both sides of the descending portion 5 and the rising portion 6. And in the inflection position of the descending part 5 and the ascending part 6, that is, the position that becomes the lowest point of the placing part 3, a wide opening 8 is formed to pull out the paper P from the roll paper 2. is doing. Further, a paper cutting part 9 as a cutting tooth is provided in front of the outlet 8 and on the lower surface of the rising part 6.

  Details of the roll paper holder 1 will be described with reference to FIGS. 3 is an exploded perspective view of the roll paper holder 1 shown in FIG. 2, and FIG. 4 is a cross-sectional view taken along line AA in FIG. As shown in FIG. 3, the roll paper holder 1 includes a holder body 10, an adjustment member 11, a paper cutting plate 12, a fixing screw 13, and a screw cover 14.

  The fixing screw 13 is inserted into the opening 4a provided in three places on the plate-like fixing portion 4 fixed along the toilet wall surface W of the holder main body 10, and fixes the holder main body 10 to the wall surface. The cover 14 is inserted and fixed to the mounting portion 3 side of the fixing portion 4 in order to hide the fixing screw 13.

  The adjustment member 11 is arranged to be slidable in the front-rear direction on the upper surface of the main body lowering portion 5 a formed so as to be inclined downward from the lower end of the fixing portion 4 of the holder main body 10. Specifically, a slide groove 7a is formed along the main body lowering portion 5a at the lower end of the side wall portion 7 above the main body lowering portion 5a of the holder main body 10, and the adjusting member 11 is formed in the slide groove 7a. Are slidably arranged. And the protrusion (not shown) convexly provided on the bottom surface of the adjusting member 11 is fitted into the concave groove 5b provided in the main body descending portion 5a, and the longitudinal direction is within the range where the concave groove 5b is formed. It is possible to slide. Further, the recessed groove 5b is formed with three recessed holes, and a protrusion (not shown) is fitted into the recessed hole, so that a click feeling can be obtained when sliding. A knob 11a extending downward is provided at the front end of the adjustment member 11. The knob 11a can be slid forward and backward with the knob 11a, and can be slid on the upper surface of the main body lowering part 5a. A display portion 5c for displaying the range is provided, and the adjustment member 11 is easily adjusted.

  As described above, the adjustment member 11 is arranged so as to overlap with the upper surface of the main body lowering portion 5a, so that the upper surface of the adjustment member 11 and the upper surface of the main body lowering portion 5a where the adjustment member 11 is not overlapped are lowered. The lower surface of the main body lowering portion 5a (the surface on the side opposite to the placement portion) and the rear surface of the adjusting member 11 that is not overlapped with the main body lowering portion 5a serve as the bottom surface of the lowering portion. And between the front end of the adjustment member 11 and the lower end of the raising part 6 becomes the paper outlet 8 of the paper P, and by sliding the adjustment member 11, the opening length in the front-rear direction of the outlet 8 is increased. It is possible to change.

  Further, the holder main body 10 is integrally formed with a plate-like rising portion 6 inclined forward, and the front side of the rising portion 6 is parallel to the fixing portion 4, that is, a toilet wall surface W. A parallel front wall 6a is formed. And the beam member 6b is shape | molded between the raising part 6 and the front wall 6a, and the paper cutting board 12 is attached between the front wall 6a and the beam member 6b. For this reason, the surface from the lower end of the rising portion 6 to the lower end of the front wall 6 a via the lower end of the beam member 6 b is the bottom surface of the rising portion 6.

  Therefore, as shown in FIG. 5 which is a side view of FIG. 1, the bottom surface of the descending portion 5 and the bottom surface of the ascending portion 6 are inclined so as to continuously descend from the fixed portion 4 side to the near side. The top surface of the portion 7 is also inclined in the same manner as the bottom surface of the descending portion 5 and the bottom surface of the rising portion 6, and the side view is a substantially parallelogram. Therefore, the roll paper holder 1 can be configured to be thin and compact as a whole, there is little interference in the installation space, and the degree of freedom of the fixed position can be ensured. Moreover, because of the simple structure, the design is also high. Furthermore, since the holder main body 10 can be screwed directly to the toilet wall W from the front, the workability is improved, and even if the holder main body 10 is made of resin, it can be firmly attached, and the holder main body 10 can be manufactured at low cost. Is possible.

  Further, as shown in FIG. 6, which is an exploded perspective view of FIG. 3 and a bottom perspective view, the paper cutting plate 12 protrudes from the paper cutting portion 9 at the front end and to the rear side (drawing port 8 side) of the paper cutting portion 9. The plurality of convex portions 12a formed and a plurality of fixing protrusions 12b for fitting and fixing the paper cutting plate 12 to the holder body 10 are formed. As the material of the paper cutting plate 12, a material having a large frictional force, such as rubber or elastomer resin, can be considered.

  Further, as shown in FIG. 7 which is a top view of FIG. 2, the rising portion 6 has ribs as convex portions from the upper end to the lower end position of the rising portion 6 along the rolling direction N of the roll paper 2. A plurality of 6r are formed. Further, also in the descending portion 5, a plurality of ribs 5 r as convex portions are formed on the upper surface of the adjustment member 11. In addition, the width of the rib 5r on the descending portion 5 side is wider on the outlet 8 side than on the fixed portion 4 side. On the other hand, the width of the rib 6r on the rising portion 6 side is the same in the front-rear direction and is the same as the width of the narrow portion of the rib 5r. As a result, the descending portion 5 side rib 5r is formed to be the same as or wider than the rising portion 6 side rib 6r.

  In the roll paper holder 1 described above, as shown in FIG. 4, the inclination angle α2 of the ascending portion 6 viewed from the outlet 8 is larger than the inclination angle α1 of the descending portion 5, and the ascending portion viewed from the outlet 8. The length L2 to the upper end of 6 is shorter than the length L1 from the outlet 8 to the fixed portion 4 that is the upper end of the descending portion 5. As a result, the outlet 8 is positioned on the front side with respect to the center of the length in the front-rear direction of the placement portion 3, so that the drawer end portion of the paper P drawn from the roll paper 2 can be used by the user. Since it is close to the near side and easily visible and can be inserted into the outlet 8 located on the side close to the user, the work of setting the roll paper 2 can be performed easily. Furthermore, since the height of the side wall 7 and the front wall 6a can be kept low, the outlet 8 can be easily confirmed. Furthermore, the placement unit 3 is an open space, does not have a lid member that closes the top, and is a simple operation of simply placing the roll paper 2 on the placement unit 3, Can be set easily with one hand.

  In the above-described embodiment, the upper surface of the main body lowering portion 5a and the upper surface of the adjustment member 11 become the lowering portion 5, but the length of the upper surface of the adjustment member 11 is longer than the length of the rising portion 6. Therefore, the length of the descending portion 5 is viewed from the outlet 8 even if the adjustment member 11 is slid to the rearmost side and the overlapping range of the adjusting member 11 and the main body descending portion 5a becomes the largest. The length of the ascending part 6 is shorter than the length from the outlet 8 to the fixed part 4 of the descending part 5.

  Hereinafter, the present invention will be described in more detail based on the usage state of the roll paper holder 1 having the above-described configuration.

  First, when the roll paper 2 is set in the roll paper holder 1, as shown in FIG. 4, the paper P is passed through the outlet 8 so that the leading end of the paper P is on the rising portion 6 side, and the placing portion 3. However, before setting the roll paper 2 on the mounting portion 3, the handle 11a provided on the adjustment member 11 is grasped by hand and moved to the fixing portion 4 side. If it puts, the opening length of the front-back direction of the drawer outlet 8 will become long, and it will become easy to set the roll paper 2 further.

  On the other hand, in the case of coreless roll paper, the adjustment member 11 is moved to the front side so that the opening surface of the outlet 8 is narrower than the roll paper 2 with core, so that the opening length in the front-rear direction of the outlet 8 is increased. Keep it short. Since the length of the outlet 8 can be adjusted by sliding the adjusting member 11 in this way, the roll paper does not fall from the outlet 8 even in the case of roll paper without a core. 3 can hold the paper until the end, and can be used regardless of whether the roll paper 2 to be set has a core or no core.

  Further, since the adjustment member 11 is superposed so as to be placed on the main body lowering portion 5a, even if the roll paper 2 rolls in the N direction when the paper P is pulled out, the adjustment member 11 and the lowering portion 5 are connected. Paper is not caught on the part and can be pulled out smoothly. Furthermore, since the knob 11a is located behind the outlet 8 and on the back side of the placement surface 3, it does not interfere with the roll of the roll paper 2 or the withdrawal of the paper P. In addition, since the slide position is guided to the display unit 5c, the user can appropriately adjust the slide position of the adjustment member 11 depending on the type of roll paper (such as the presence or absence of a core).

  It is possible to form the adjusting member 11 on the ascending part 6 side, or on both the descending part 5 and the ascending part 6, but if the position of the lower end of the ascending part 6 changes, the roll paper 2 The contact position with the drawn paper P is also changed, and the feeling given to the user when the paper P is drawn or cut may be greatly changed. Therefore, the adjustment member 11 is preferably formed on the descending portion 5 side. In addition to forming the adjusting member 11 in the descending part 5 and the ascending part 6, it is also conceivable that the entire ascending part 6 is configured to be slidable in the front-rear direction with respect to the descending part 5.

  Next, the drawing operation of the paper P will be described. When the paper P is pulled out from the roll paper 2 set on the placement unit 3 through the outlet 8 to the front side, the roll paper 2 set on the placement unit 3 is subjected to a moment toward the front side but is inclined. The roll paper 2 is controlled by the descending portion 5 having a small inclination angle α1 while the upward movement of the roll paper 2 is restricted by the rising portion 6 having a large angle α2 to prevent the roll paper 2 from jumping out from the placing portion 3. By allowing the movement to the back side to some extent, a large resistance is not generated in the rolling of the roll paper 2, and the paper P can be drawn out smoothly. Furthermore, since the direction in which the roll paper 2 is set is not different from that of the conventional roll paper holder, the user can set it with the same feeling as that of the conventional paper holder.

  Further, when the roll paper 2 is drawn, the roll paper 2 is in contact with the rib 6r formed at the lower end position of the rising portion 6 as shown in FIG. Since the contact area between the portion 6 and the roll paper 2 is reduced, the sliding resistance generated during the drawing can be reduced, and the paper P can be drawn smoothly.

  On the other hand, as shown in FIG. 7, ribs 5r are also formed in the descending portion 5, and the ribs 5r are formed to have the same width as or wider than the ribs 6r. While the sliding resistance of the ascending portion 6 that is strongly pressed when moving is reduced, while the moderate inclination resistance is given to the descending portion 5 while the inclination angle is gentle, the set roll paper 2 is Since it is allowed to move toward the fixed portion 4 side, the roll paper 2 can be pulled out more smoothly.

  Furthermore, the rib 5r provided in the descending part 5 is formed wider on the outlet 8 side than on the fixed part 4 side. Therefore, when the remaining amount of the roll paper 2 is reduced as shown in FIG. 9, even if the diameter of the roll paper 2 is reduced and the sliding resistance due to its own weight is reduced, the contact between the roll paper 2 and the descending portion 5 is achieved. The position has moved to the outlet 8 side (see FIG. 4), and since the contact area between the roll paper 2 and the rib 5r increases, the sliding resistance due to contact increases and the decrease in sliding resistance due to its own weight is negated. Thus, even if the diameter of the roll paper 2 changes, unnecessary movement does not occur during rolling by pulling out, and the user can easily pull out the roll paper 2 regardless of the state of the roll paper 2.

  Note that the width of the rib 6r of the rising portion 6 may be made narrower, and the width of the rib 6r may be narrower than the rib 5r of the lowering portion 5 over the entire rib 6r. Further, the rib 6r of the ascending portion 6 and the rib 5r of the descending portion 5 do not have to be formed at the same interval, and the rib 5r of the descending portion 5 is formed at a closer interval so as to contact the roll paper 2 The sliding resistance may be increased by increasing the area. Further, the rising portion 6 is not provided with ribs (or the rib 6r is provided only on a part on the outlet 8 side), and only the lowering portion 5 is provided with the ribs 5r so that it is lower than the rising portion 6. The contact area of the part 5 may be increased. That is, the roll paper 2 changes its diameter with use, but the width of the rib 5r of the descending part 5 that contacts the roll paper 2 is the rib of the ascending part 6 at any time of the diameter change. It only needs to be wider than 6r (preferably at all times of diameter change). Further, the widths of the plurality of ribs 5r provided in the descending portion 5 do not have to be the same, and the widths of the plurality of ribs 6r of the ascending portion 6 are also the same, so that the center side is narrower than the both end sides. Such modifications are possible. As is clear from the above description, the rib width in the present invention refers to the total width in the width direction in contact with the roll paper 2 rather than the width of each of the ribs 5r and 6r.

  Next, the cutting operation of the drawn paper P will be described. As shown in FIG. 10 which shows the paper cutting state in FIG. 4 and FIG. 11 which is a BB end view in FIG. 10, the drawn paper P is pulled up to the paper cutting plate 12 side and comes into contact with the convex portion 12a. Further, the paper cutting surface is brought into contact with the paper cutting portion 9 and the paper P is cut so that the front end of the paper P faces the top of the placement portion 3. Since the paper P abuts on the paper cutting portion 9 in a state where the drawing is restricted by the convex portion 12a, the paper P can be easily cut with one hand. That is, at the time of cutting, the convex portion 12a functions as a stopper that prevents the paper from being fed out.

  Further, as shown in FIG. 6, the surface of the paper cutting plate 12 that comes into contact with the paper P is provided with a plurality of convex portions 12 a. Therefore, when cutting, as shown in FIG. A gap is formed between the surface 12c and the paper P, and the paper P that has come into contact after cutting is prevented from sticking to the surface 12c of the paper cutting plate 12, and the paper P hangs downward. In addition, it is possible to secure a picking allowance when the paper P is pulled out next time.

  Furthermore, since the convex portion 12a is formed in a long rib shape along the feeding direction of the paper P, there is also an effect of preventing the paper P from shifting in the width direction even when the paper P is cut. P can be cut more reliably. In addition, since the convex portion 12a protrudes so that the cross section in the feeding direction is a curved surface, the paper P comes into contact with the curved surface, so that when the paper P is cut, the paper P is placed at one place in the feeding direction of the paper P. Care is taken so that the paper P is not torn by force.

  Next, a modification of this embodiment is shown in FIG. FIG. 12 shows the roll paper holder 1 having a lid member 16. The holder body 10 and the lid member 16 are separate and configured to be detachable. After the roll paper 2 is set in the same manner as in the above embodiment, the inner peripheral surface of the lower end of the lid member 16 and the holder The lid member 16 is set by fitting the outer peripheral surface of the upper end of the main body 10 together. By providing the lid member 16, the roll paper 2 is not exposed, and dirt such as flying water and dust from the adjacent hand-washer in the toilet space does not adhere to the paper, which is sanitary. In addition, the appearance is simple because it is a simple box. The cover member 16 covers the roll paper 2 as shown in FIG. 13, which is a CC cross-sectional view of FIG. 12, but even the unused roll paper 2 is between the cover member 16 and the roll paper 2. A gap is formed, and sliding resistance due to contact between the roll paper 2 and the lid member 16 does not always occur.

Next, a second embodiment of the present invention will be described.
In the present embodiment, as shown in FIGS. 14 and 15, in the side view of the holder main body 20, the front surface is parallel to the wall surface, and the top surface and the bottom surface are orthogonal to the wall surface. It is almost rectangular. However, as shown in FIG. 16, which is a DD cross-sectional view of FIG. 14, also in this embodiment, as in the first embodiment, the fixing portion 24 fixed along the wall surface W and the front from the fixing portion 24. A descending portion 25 that is inclined downward, an ascending portion 26 that is inclined upward from the front of the descending portion 25, and an outlet 28 that is wide open to draw the paper to the inflection position of the descending portion 25 and the ascending portion 26. I have. Further, a paper cutting part 29 as a cutting tooth is provided in front of the outlet 28 and on the lower surface of the rising part 26. On top of that, it is formed so as to have a square appearance.

  By adopting such a configuration, the roll paper holder 1 can be formed into a rectangular box shape while maintaining the inclined shapes of the descending portion 25 and the ascending portion 26, without impairing the ease of pulling out the roll paper 2. The appearance can be changed.

  As mentioned above, although this invention was demonstrated through embodiment, this invention is not limited to the above-mentioned embodiment, You may change the design suitably in the range which does not deviate from the technical idea of this invention.
