Description

  The present invention relates to an improvement of a roll paper holder (hereinafter simply referred to as a paper holder) that rotatably supports roll paper such as toilet paper and paper napkin, and in particular, a paper holder that can be easily pulled out with one hand and cut to a required length. About.

  As shown in FIG. 6, the conventional paper holder 10 covers a fixed plate 11 attached to a wall surface of a toilet or kitchen, side plates 12 and 12 that rotatably support the roll paper R, and an upper surface of the roll paper. And a cover 13. The cover 13 is composed of a main body part 13a that is pivotably mounted with shafts S and S on both sides at the rear end, and a cutter part 13b that is bent at the front end of the main body part 13a.

  When the conventional paper holder 10 is used, since the cut portion of the roll paper and the tip of the cutter portion 13b are in contact with each other, the end piece cannot be gripped and is difficult to pull out. Therefore, when the lower side of the roll paper R is pressed and turned, one end of the roll paper R is caught in the inner part of the cover 13 and may hang down for a long time. Further, since the cover 13 is merely placed on the roll paper, when the paper is to be cut out with one hand, the cover is lifted and the cover 13 has to be pressed with the other hand. Therefore, the roll paper cutting operation is extremely difficult for a person who has a functional disorder in one hand due to hemiplegia, injury, etc., and the use of the toilet is particularly painful.

In view of this point, as a paper holder that can be cut with one hand, for example, a cover that is provided with a spiral spring so that the cover always presses the upper part of the roll paper with this spring has been proposed ( For example, Patent Document 1).
JP-A-5-220058

  According to Patent Document 1, as the roll diameter of the roll paper decreases with use, the inclination angle of the cover changes and the tension of the spring becomes weaker. For this reason, if one end of the rolled paper is held with one hand and pulled to the left or right, the cover will rise, making it difficult to cut it with one hand, and the cover cannot be maintained in a vertical state. There was a problem that it was difficult.

  The present invention makes it possible to cut easily and reliably with one hand even if the roll diameter of the roll paper changes, and also allows the paper to be cut even if pulled in the left, right, or rear direction, and facilitates the replacement of the roll paper. This is the issue.

  The present invention is a roll paper holder in which a roll paper rotatably supported is cut off at the front end of the cover, the cover being capable of pressing the roll paper by a weight and a tension spring, and at the front end. A substantially inverted V-shaped cutter portion is provided (claim 1).

  When this means is used, the roll paper is always pressed by the cover in which the weight and the tension spring act even if the roll diameter of the roll paper is reduced, and a part of the end piece of the roll paper is a substantially inverted V-shaped valley. Looking into the club. Therefore, when the end piece is grasped with one hand and pulled out and pulled left or right or rearward, the cover is not lifted up, and a piece of paper having a desired length is cut by the cutter portion.

  In the present invention, it is preferable that the cutter unit is a needle group blade in which a large number of needles are arranged in parallel (Claim 2). In this way, when one end of the roll paper is gripped and pulled left or right or rearward, a part of the roll paper is easily caught by the left end or right end needle.

  Moreover, the structure (Claim 3) whose cutter part is a sawtooth-like thing which has a tooth tip toward the outer side from a center part is suitable. If it does in this way, a part of roll paper will be easily caught on the tooth tip of a left end or a right end, and will be cut off still more easily.

  Furthermore, considering the replacement of the roll paper, a configuration in which the cover can be maintained in an upright state (Claim 4) is preferable. A specific configuration can be achieved by means for attaching the upper end of the tension spring to the tip side from the pivot point of the cover.

  In the paper holder of the present invention, since the cover presses the roll paper by the cooperative action of the weight and the tension spring, and a part of the end piece of the roll paper looks into the substantially inverted V-shaped valley, When a piece is grasped with one hand and pulled left or right or rearward, a paper piece of a desired length can be easily and reliably cut off by the cutter unit without lifting the cover.

  In addition, if the cutter part is configured with a needle group blade, a piece of paper can be cut out without causing paper scraps, and if it is configured with a serrated object, a part of the end piece of the roll paper can be easily caught, and even easier, And it can be cut out reliably.

  If the cover can be maintained in an upright state, the roll paper can be replaced more easily.

  The paper holder of the present invention can be used as a holder for various types of roll paper. However, since the roll paper can be cut out with one hand, there is an advantage that it is particularly convenient when used for a toilet for disabled or care recipients. .

  Embodiments of the present invention will be described with reference to the drawings. In FIG. 1, a paper holder H includes a fixing plate 1 that is fixed to a wall surface of a toilet with screws, an adhesive, and the like, side plates 2 and 2 that can rotatably support a roll paper R, and an upper portion between the side plates 2 and 2. And a cover 3 provided so as to be swingable by shafts S and S.

  The cover 3 is provided with a projection T on the tip side from the pivot point of the shaft S, and a hook at the upper end of the tension spring 4 is attached to the projection T, and the upright state is maintained as shown in FIG. Made possible.

  As shown in FIG. 2, the cover 3 is composed of a lower cover portion 3a, an intermediate cover portion 3b, and an upper cover portion 3c that are integrally fixed by fixing means such as ultrasonic bonding and adhesive, and the intermediate cover portion 3b. Is provided with two concave portions on the left and right sides, and a weight 5 is provided in each concave portion so that the roll paper R can be pressed in cooperation with the tension spring 4. In this case, it is preferable that the combined pressing force of the weight 5 and the tension spring 4 is at least 100 g. This is because when the weight is less than 100 g, the cover 3 tends to be lifted by the cut-out operation of the drawn roll paper, and it becomes difficult to cut out the piece of paper.

  As shown in FIG. 3, a substantially inverted V-shaped cutter portion C composed of a row of needle group blades in which a large number of needles 6 are arranged in close contact with each other is provided at the tip of the cover 3. As shown in FIG. 3 (b), when this needle group blade is configured such that the needles 6 having a needle tip point a of 1 mm or less are arranged side by side so that the needle head pitch b is 2 mm or less, generation of paper waste The risk of injury and injury can be eliminated, and the ease of cutting and certainty can be improved.

  The substantially inverted V-shaped cutter portion C may be formed of a metal or resin saw-toothed object instead of the needle group blade. 4 (a) and 4 (b) show a metal serrated object 7, and FIGS. 5 (a) and 5 (b) show a resin serrated object 71. FIG. These metal or resin saw-toothed objects 7, 71 are formed so that the left and right tooth tips 7a or 71a face in opposite directions from the substantially inverted V-shaped central portion, respectively. Consists of sheets.

  In these cases, if the lower surface of the front end portion of the cover is a flat surface or a tapered surface, a gap is always formed between the front end portion and the roll paper regardless of changes in the roll diameter of the roll paper with use. This is preferable because roll paper can be easily pulled out.

  The roll paper R is supported on the inner side of the side plates 2 and 2 with a vertically swingable bracket so that it can be inserted into and removed from the paper core. Depending on the type of roll paper, It is possible to employ a structure in which a concave portion is provided in the concave portion, and a support shaft that is inserted into the roll paper is engaged and detached in the concave portion.

  Although the upper end hook of the tension spring 4 is engaged with the protrusion of the cover, the tension spring 4 can also be engaged with the end of a plate-like arm attached to the pivot point of the cover.

  Further, as shown in FIG. 2, the cutter part C is provided with a tooth tip cover 8, which is provided with a compression spring at the rear part thereof so as to be able to protrude and retract on a needle group blade or a sawtooth object via a presser plate 9. Since the tip portion of the tooth tip cover 8 covers the tooth tips of the needle group blades or saw-toothed objects, the risk of injury can be eliminated and the safety can be improved.

  Furthermore, the dimensional ratio between the width L corresponding to half of the cutter portion C and the depth D of the substantially inverted V shape is preferably in the range of 1: 0.06 to 1: 0.10. This is because when it is less than 0.06, a part of the roll paper tends to be difficult to catch on the needle or tooth tip at the left end or right end of the cutter portion, and when it exceeds 0.10, the generation of paper waste tends to increase. Because it becomes.

  As the needle group blade, a spinning card cloth can be used. Further, although the needle 5 is illustrated as a straight needle, the shape of the needle 5 may be a curved needle whose tip is bent downward. The cross-sectional shape of the needle tip may be any shape such as a circle, a square, or a rectangle. Can do.

  In addition, as the metal sawtooth, a spun metallic wire can be used. In this configuration, it is advantageous in terms of material and production cost compared to needle group blades, and it is easier to change the shape of the tooth tip according to the paper quality, thickness, etc. of the roll paper. There is an advantage that you can.

  As a material for spinning card cloth and metallic wire, a material having rust prevention and strength (rigidity) is suitable.
