Description

  The present invention provides a roll paper such as toilet paper or a roll paper air core receiver for supporting a roll-wrapped sheet-like material similar to the roll paper so that it can be rotated by the air core so that it can be returned inward after being tilted outward. It relates to the improvement of the holder.

As this type of roll paper holder, for example, as described in Patent Document 1 below, a single sheet of flexible pieces (leaf springs) are fixed to the left and right side rear portions of the roll paper holder. At the same time, the left and right air core receivers are tilted outwardly against the bending and resilience of the flexible piece by the roll paper insertion external force. When the sheet is inserted into the roll paper air core, the roll paper holder is known which can pivot the roll paper to the left and right air core receivers by returning the flexible piece inwardly by its flexural rebound force.
JP-A-8-131368

  In the conventional example described in Patent Document 1, when inserting each air core receiver into the roll paper air core, first, a paper cutting plate is opened upward, and lock plates provided on both sides thereof are provided on the left and right of each roll paper air core receiver. After removing each air core receiver from the outside by being removed from the outside, the roll paper is tilted outward between the air core receivers against the elastic force of the flexible piece. When the air core receivers face the opposite sides of the roll paper core tube, the roll paper air core receivers are returned inward by the flexural resilience of the flexible pieces, Engage the roll paper core receivers to pivotally set the roll paper to the left and right air core receivers, and then close the paper cutting plates so that the lock plates on both sides of the paper are placed outside the air core receivers. Opposed and prevented inward tilting A roll paper holder and can be used in.

  Therefore, in the above conventional example, in the state where the paper cutting plate is opened and the lock plate is removed from the outside of the left and right roll paper air core receivers, there is no member that restricts the inclination of the air core receivers inward and outward, and each air core Since the important flexible piece for returning the receiver inward is a single plate, the left and right air core receivers are in an extremely unstable state that is easy to move from inside to outside, left and right, so roll paper on the left and right air core receivers There is an essential and big problem that the flexible piece bends upward and becomes unusable if the roll paper is inserted and set by force.

  In the above conventional example, when a wide roll paper having a roll paper width within the JIS standard range is pivotally set to the left and right air core receivers, the space between the left and right air core receivers is widened, so the paper cutting plate is closed to the use position. If it tries to do so, the lower end of the lock plate on the left and right of the paper cutting plate will hit the upper surface of each air core receiver, the paper cutting plate will not close, and if you try to close it forcibly, the flexible piece will bend downward, as a roll paper holder In addition to having a major problem that it becomes unusable, if you try to eliminate the above problem by widening the distance between the lock plates, this time, there will be one important flexible piece to return the air core receiver inward. Because it is a single plate, when the roll paper is fed out, the roll paper easily moves from side to side and left and right together with the left and right air core receivers, and there is a risk that the roll paper will come off the air core receiver during feeding. This also mutually conflicting major problem that useless there as a roll paper holder.

  Further, in the above conventional example, when inserting the right and left air core receivers into the roll paper air core by tilting outward with the roll paper insertion external force against the bending and repelling force of the flexible piece, the important flexible piece is one. Since it is a single plate, it can be easily inserted in the length direction of the flexible piece, that is, from the bottom to the top, but if it is inserted in the width direction of the flexible piece, that is, from the front side to the back side, the free end of the flexible piece Since an unreasonable slanting stress is applied in the width direction, the flexible piece free end bends and it becomes difficult to insert the roll paper, and when trying to insert it forcibly, the flexible piece bends in the back direction, and as a roll paper holder Since it is no longer usable, the roll paper cannot be inserted into the roll paper core from the front to the back and cannot be pivotally set. Is it troublesome to hit the pivot set? Also there is a big problem that it is inconvenient.

  The present invention eliminates unstable elements of the left and right air core receivers by improving means for returning the left and right roll paper air core receivers in the roll paper holder after inclining outward by an external force, and rolls against the air core receivers. The purpose is to eliminate the direction of the paper pivot set.

  An object of the present invention described above is to provide a paper cutting plate on the upper front outer peripheral surface of the roll paper that is rotatably supported by the roll paper air core receiver provided facing the left and right side bodies in the plane substantially U-shaped roll paper holder. In forming a roll paper holder that can press the lower surface of the front side and cut the roll paper feeding portion passing through the lower surface with the front edge of the paper cutting plate, the left and right side bodies have a rear portion and most of the inner surface. In addition to forming an open recess, a roll paper insertion guide slope is formed inside each roll paper air core receiver, and each air core receiver is pivotally supported on the front side of the left and right arms while being prepared in advance. The rear part of each arm is pivotally supported forward by a pivot piece protruding from the upper and lower sides of the front left and right vertical plates of the holder insertion plate, and between the front outer surface of each arm and the inner surface of the side body recess. Apply elastic springs (coil springs and leaf springs) to the In the state of interposing against the repelling force, each air core receiver is engaged with the side body recess forward from the rear open end together with the vertical plate, and then the insertion plate is fixed to the rear surface of the holder. I was able to achieve it.

Since the present invention employs the above-described means, the following effects can be obtained.
According to each of the first and second aspects of the present invention, the roll paper air core receiver is externalized by a roll paper insertion external force that resists the elastic force of the elastic spring (coil spring or leaf spring). After the tilting of the roll paper, the release of the external force at the time when the roll paper insertion is completed causes each air core receiver to return to the position of use with the return elastic force of the elastic spring together with the arm. Regardless of whether the paper cutting plate is opened or closed, the inner side of each arm can be elastically contacted with the outer surface of the vertical plate, so that the left and right air core receptacles can be fluttered both inside and outside, left and right, even when the paper cutting plate is opened. Since a stable counter use standby position can be ensured without moving, there is an excellent effect that the roll paper pivot setting operation for the left and right roll paper air core receivers can be carried out in a random manner.

  In addition, since the paper cutting plate according to the present invention does not require a downward lock plate as in the above-described conventional example, the left and right air core receivers are used as in the case where a roll paper having a large paper width is pivotally set to the left and right air core receivers. Even when the interval is slightly widened, the paper cutting plate can be reliably closed to the use position, and the outward tilting of each air core receiver in the opposed return state is caused by the elastic springs ( The coil springs and leaf springs) can be surely blocked, so each air core receiver in the middle of feeding out the roll paper does not move in and out, and the roll paper does not come off the air core receiver. There is also an excellent effect that roll paper feeding can be executed.

  In addition, since the left and right arms in each of the above inventions are not bent flexibly or deformed, the left and right air core receivers are tilted outwardly against the elastic force of the elastic spring by the roll paper insertion external force, and the roll paper air core When inserting into the arm, even if upward stress is applied to the free end of each arm as in the case of inserting the arm in the width direction, that is, from the front to the back or diagonally, each arm does not flex or deform Therefore, since the directionality of the pivotal support set of the roll paper with respect to each air core receiver can be eliminated, there is also an excellent effect that the use is simple.

  As in the invention of claim 3 in the present invention, if the elastic spring (coil spring or leaf spring) is engaged with a boss provided outward at the front part of each arm, the positioning is performed. In the state where the outer ends of the elastic springs are elastically contacted with the inner surface of the side body recess, the air core receiver is engaged with the side plate recess forward from the rear open end together with the vertical plate. Since the position of the elastic spring spring does not change to delirium, it is possible to add the effect that the mounting workability of each air core receiver is improved, and as in the invention of claim 4, the front of the arm to be pivotally supported is provided. If the air bearing is pivotally supported on the front side of each arm by press-fitting a pivot pin that is loosely inserted inwardly from the outside into the outer boss, the center hole of each air core is supported. The effect that the work and the retaining work can be performed simultaneously can be added.

  If the roll paper insertion guide slope is a convex convex slope as in the invention of claim 5 in the present invention, an effect that the roll paper insertion pivoting operation with respect to the roll paper air core can be performed more smoothly can be added. It was.

  A rough basic embodiment of a roll paper holder for carrying out the present invention is as follows. The left and right side bodies 2 in the roll paper holder 1 formed into a substantially U-shaped plane with plastic or metal as shown in FIGS. 2 is prepared so that it can be returned inward after being tilted outward as shown in FIGS. 1 and 3 by means described later. The core tube 4A (or air core) is rotatably supported as shown in FIG.

  Next, pivots 5A on the left and right sides of the rear part of the holder side body 2 as shown in FIG. 1 and FIG. 4 so that it can be tilted, and the lower surface 5B of the front side of the paper cutting plate 5 is pressed against the upper front peripheral surface of the roll paper 4 by self-gravity as shown in FIG. In the present invention, a general configuration of a roll paper holder is adopted in which the feeding portion 4B of the roll paper 4 passing through the lower surface 5B can be cut with a finger or the like at the front edge 5C of the paper cutting plate 5 as shown in FIG.

  Next, as a best mode for carrying out the present invention, a specific example in which the roll paper core receiver 3 in the roll paper holder as described above is mounted on the holder side body 2 will be described in detail below. Then, as shown in FIG. 2 and FIG. 5, the left and right side bodies 2 are previously formed with recesses 6 in which the rear portion and most of the inner surface are open, while the left and right air core receivers 3 are respectively provided with roll paper 4. In order to form an annularly inclined ring-shaped guide slope 3A for assisting insertion of the air core and to mount these air core receivers 3 opposite to the left and right side bodies 2, the left and right arms 7 as shown in FIG. , And a pivot pin 8 loosely inserted inwardly from the outside into the hole 7B of the front outer boss 7A is press-fitted into the pivot hole 3B of each air core receiver 3 as shown in FIG. The support 3 can be rotated on the front side of the left and right arms 7 with a pivot pin 8 as a fulcrum. To pivot.

  And each pivotal support piece 10 protruding oppositely on the upper and lower sides of the left and right vertical plates 9A protruding forward on the holder insertion plate 9 as shown in FIG. As shown in FIG. 6, the pivot projections 7C as shown in FIG. 2 projecting vertically from the rear portion of the arms 7 in the pivot support holes 10A are resisted against the repulsive force inherent to the material of the pivot pieces 10, respectively. As described above, the left and right arms 7 which are pivotally supported by the air core receiver 3 as described above are pivotally supported on the holder insertion plate 9 so as to be capable of opening and closing with the pivot projection 7C as a fulcrum as shown in FIG. Prepare.

  Thereafter, an elastic spring S such as a coil spring (or a leaf spring such as a one-dot chain line) is inserted outwardly into the boss 7A of the arm 7 as shown in the above drawings, and the holder insertion plate 9 is inserted into the rear surface of the holder. 7, one elastic spring S is compressed while being inclined as shown in FIG. 7, and its outer end is elastically contacted with the inner surface of the rear open end 6A of the side body recess 6 as shown in FIG. When the holder insertion plate 9 is moved forward as shown in FIG. 9 without tilting, the outer end of the elastic spring spring S is brought into elastic contact with the inner surface of the rear open end 6A as shown in FIG. 10 when the inner stopper projection 7D of each arm 7 is disengaged from the rear open end 6A of the side body recess 6 by the elastic force of the elastic spring S on the outer surface of the vertical plate 9A. Each of the air core receivers 3 returns to the inward facing direction as shown in FIG. The inner surface or each arm 7 on the outer surface of the inward tilting of the air-core receiving 3 the vertical plates 9A, is elastically contacted the stopper projection 7D allows blocking with.

  Next, with each air core receiver 3 returned to the opposite position, the holder insertion plate 9 is further pushed into the usable position as shown in FIG. 3, and the insertion plate 9 in this usable position is screwed or locked. By fixing to the rear surface of the holder 1 with a well-known fixing means such as a piece or bonding, the roll paper air core receiver 3 is resisted against the elastic force of the elastic spring S as shown in FIG. When the roll paper insertion external force is applied and tilted outward with the rear portion of each arm 7 as a fulcrum, the external force is released when the inner surface of each air core receiver 3 faces the outer edge of the roll paper core tube 4A as shown in FIG. Each of the air core receivers 3 and the arms 7 are returned to each other as shown in FIG. 12 by the return elastic force of the elastic spring S, so that the roll paper 4 is attached to the left and right air core receivers 3 by the core tube 4A. The row of the present invention which can be pivotally supported as shown in FIG. I was able to configure the paper holder.

  However, the elastic force of the elastic springs (coil springs and leaf springs) is applied to the left and right air core receivers 3 when the roll paper 4 pivotally supported as shown in FIGS. While the paper core tube 4A is set so as not to be pulled out and the used core tube 4A can be removed, the pivot support means at the rear of each arm with respect to the holder insertion plate 9, and the front of each arm The pivot support means of each air core receiver 3 can employ well-known retaining pivot support means in addition to the pivot support means described above, and the roll paper holder 1 can be a rear face plate 1A or a holder insertion plate. 9 is used by attaching it to the wall surface a of the place of use with a concrete screw nail n as shown in FIG.

The configuration of the present invention is as described above, and the use operation example will be described below.
First, the initial state of the roll paper air core receiver 3 is such that the inner side of each arm 7 or its stopper projection 7D elastically contacts the outer side of the vertical plate 9A as shown in FIG. In this state, after the paper cutting plate 5 is opened upward as shown in FIG. 1, the both sides of the roll paper are faced from the front side to the back side between the left and right roll paper cores 3. 3 starts rubbing against the air core receiving guide slope 3A in the direction indicated by the arrow in FIG. The arm is tilted outward with the rear part of the arm as a fulcrum as shown in FIG.

  Then, when the guide slopes 3A of the air core receivers 3 are evenly opposed to the outer edge of the roll paper core tube 6A, the air core receivers 3 together with the arms 7 are now subjected to the return elastic force of the elastic spring S as shown in FIG. Therefore, the outer edge of the roll paper core tube 4A can be tightly supported by the guide slopes 3A of the left and right air core receivers 3, and the roll paper 4 is attached to each air core receiver 3 with its core tube 4A (or air core) as shown in FIG. As shown in FIG. 12, it can be pivotally set.

  Next, the lower surface 5B of the front side of the paper cutting plate 5 is pressed against the upper front peripheral surface of the roll paper 4 by self-gravity as shown in FIG. 4, and the roll paper 4 passing through the lower surface is fed out to a desired length. By pulling the feeding portion 4B obliquely outward as shown in FIG. 4, it can be cut and used with the front edge 5C of the paper cutting plate 5.

  In order to remove the used roll paper core tube 4A from the roll paper holder 1, the empty core tube 4A is rubbed against the air core receiving guide inclined surface 3A against the elastic force of the elastic spring S. However, by pulling out upward or forward, the empty core tube 4A can be removed from the roll paper holder 1, and at the same time, each of the air core receivers 3 returns to its original shape as shown in FIG. A new roll paper 4 can be pivotally set as described above and used again.

  In addition to the ring-shaped flat slope as described above, the guide slope 3A inside the left and right air core receivers 3 may be a convex-convex arc slope as shown in FIG. The insertion direction for pivotally setting to 3 is true from the lower side of each air core receiver 3 as shown in the vertical sectional view shown in FIG. 14 instead of inserting from the front side of the roll paper holder to the back side as described above. It is also possible to pivotally set the roll paper 4 to each air core receiver 3 as shown in FIG. 15 by tilting each air core receiver 3 together with the arm 7 with the roll paper 4 inserted upward or obliquely upward.

  In addition to roll paper such as toilet paper as described above, the roll paper holder according to the present invention naturally feeds and cuts rolled-up sheet-like materials similar to roll paper such as wrap films and long thin continuous bags in supermarkets and the like. it can.
