Description

  The present invention relates to a roll holder. More specifically, the present invention relates to a roll holder that can rotatably hold an inner core of a roll obtained by winding a paper or a plastic bag in a roll shape around a cylindrical core portion.

  Conventionally, rolls obtained by winding paper in a roll form include toilet paper and paper towels. For example, as a roll holder A that holds toilet paper, the inside of a pair of arms protruding forward from the main body, each upward Some of them have a pair of protruding members that can be folded only and face each other. The projecting member is pivotable by the arm within a range of about 90 ° and is maintained in the horizontal direction by a coil spring.

  However, in the roll holder A, since the coil spring that biases the protruding member is relatively weak, there is a roll holder B that uses a plate spring having a large biasing force instead of the coil spring (see Patent Document 1).

No. 5-11835

  In the roll holder B, since the protruding member is maintained by the large biasing force of the leaf spring, the toilet paper does not fall out of the protruding member when the paper is pulled out strongly.

  However, since the protruding member rotates in a range of about 90 ° in the vertical direction, when the protruding member is inserted into the core of the toilet paper, the top of the toilet paper is exposed from the upper surface of the main body. Must be lifted. At this time, since the paper cutter provided at the rear upper end of the main body is also lifted, when providing a shelf for placing a fragrance container or a vase in the upper part of the main body, between the main body and the shelf A large space is required, and the upper periphery of the roll holder cannot be made compact.

  In view of the above circumstances, an object of the present invention is to provide a roll holder capable of reducing the opening degree of a paper cutter and easily mounting a roll when the roll is mounted.

  The roll holder of the present invention is fitted to a holder main body, a side cover assembled to a pair of side portions projecting forward of the main body, and a support portion provided at a lower portion on the back side of an opening opened in the wall surface of the cover. A holding claw to be worn, and the holding claw can be tilted obliquely forward of the holder body with the support portion as a fulcrum, on the back side upper part of the opening of the side cover, and on the back side of the holding claw A roll spring formed integrally with the holder main body via the enclosure and supported by the support portion, and locking protrusions are formed on both side surfaces of the holding claw, A guide that abuts against the locking protrusion is formed in the vicinity of the support portion.

  As described above, according to the present invention, since the holding claw is inclined, the opening degree of the paper cutter can be made smaller than before and can be attached close to the shelf at the upper position of the holder body.

  In addition, by forming the lower portion of the holding claw on an arc surface, the operation of attaching the roll becomes a locus of a reciprocating arc from the lower part of the holder body toward the diagonally forward direction and from the diagonally forward direction to the downward direction with the elbow as a fulcrum. For this reason, the movement of the arm becomes smooth and the roll can be easily mounted.

  Hereinafter, the roll holder of the present invention will be described with reference to the accompanying drawings.

FIG. 5 is a sectional view taken along the line CC in FIG. 1, FIG. 6 is an enlarged view of the sectional view taken along the line DD in FIG. 5, FIG. 7 is a left side view of the right side cover, and FIG. FIG. 9 is a rear view of the right side cover, FIG. 10 is an enlarged view of a cross section taken along line EE in FIG. 9, FIG. 11 is a side view of the holding claw, and FIG. 12 is a plan view of the holding claw. 13 is a front view of the holding claw.

  As shown in FIGS. 1 to 6, the roll holder according to the embodiment of the present invention is attached to a wall surface such as a cabinet 1 or a tile so that the core portion Pa of the toilet paper P can be held, for example. The holder main body 2, the side cover 4 assembled to the pair of side portions 3 projecting forward of the main body 2, and the support portion 6 provided in the lower part on the back side of the opening 5 opened in the wall surface of the cover 4 are fitted. It comprises a holding claw 7 to be worn. The holding claw 7 is supported by the support portion 6 so as to be inclined obliquely forward of the holder body 2 with the support portion 6 as a fulcrum.

  The holder body 2 has a U-shape in which the side part 3 is formed into a cavity. After the side cover 4 is inserted into the cavity from the back side of the holder body 2, the base 8 and the side part are formed. 3 is assembled with an adhesive or the like. As shown in FIGS. 3 and 8 to 9, the positioning protrusions 9 a and 9 b when inserted into the side portion 3 of the holder body 2 are formed on the back surface and the rear end side surface of the side cover 4 during the assembly. 9c and 9d are respectively formed. In the present embodiment, the paper cutter 10 is provided on the upper portion of the base 8 on the rear side of the holder main body 2 so as to be opened and closed. However, the paper cutter 10 may be provided in the cabinet 1, for example. In addition, 11 is a screw hole for attaching to a wall surface.

  As shown in FIGS. 4 to 5, 7, and 9 to 10, the opening 5 of the side cover 4 is inclined to the front of the holder body 2 and is open on the back side of the opening 5. A U-shaped enclosure 12 is formed, and a leaf spring 13 is provided at the upper part on the back side of the opening 5. The leaf spring 13 is formed in a curved shape so that the front surface is concave and extends to the lower portion of the holding claw 7 on the back side, and a bulging portion 14 is formed at the tip. The support portions 6 are respectively provided at the lower opening ends of the enclosure portion 12 and have a U-shape. Supporting protrusions 23 that protrude from both side surfaces of a holding claw 7 to be described later are fitted into the fitting recess 15 of the support portion 6 so that the holding claw 7 can be rotated to the inside and outside positions of the opening 5. I support it. In the present embodiment, when the holding claw 7 rotates and enters the opening 5, the tip bulging portion 14 of the leaf spring 13 biases the back surface of the holding claw 7 so that the holding claw 7 is always opened. 5 is projected from the inside. In addition, it is preferable to form the guide 16 which contact | abuts to the latching protrusion 24 formed in the side part of the said support part 6, for example, upper part, on both sides | surfaces of the holding claw 7 mentioned later. The guide 16 and the locking projection 24 prevent the holding claw 7 from rotating and entering too far into the opening 5, and the holding claw 7 pushes up the leaf spring 13 and falls off the support portion 6. Can be prevented.

  As shown in FIGS. 11 to 13, the holding claw 7 is formed in a hollow shape, and is formed in an arc surface so that the upper end surface can contact the inner cylindrical surface of the core portion Pa of the toilet paper P. The holding portion 20, the back portion 21 curved in the longitudinal direction, the wall portions 22 on both sides, and the support protrusion 23 formed on both side surfaces below the wall portion 22 and the upper position away from the support protrusion 23. It is comprised from the stop protrusion 24 and the shoulder part 25 formed in the lower end of the said back part 21. As shown in FIG. Since the holding claw 7 has the support protrusion 23 positioned below, the center of gravity of the holding claw 7 is located away from the support protrusion 23. For this reason, when the support protrusion 23 of the holding claw 7 is fitted into the fitting recess 15, the shoulder 25 formed at the lower end of the holding claw 7 is engaged with the lower edge 26 of the opening 5, and the holding claw 7 is supported diagonally forward (see FIGS. 4 to 6). In the present embodiment, since the holding claw 7 is inclined, when the holding claw 7 is rotated, the moving distance in the vertical direction of the holding unit 20 is smaller than that of the conventional one, and the core portion Pa of the toilet paper P is reduced. Since the direction of insertion into the holding claw 7 is obliquely downward, the opening degree of the paper cutter 10 when the toilet paper P is mounted and removed can be made smaller than before. In addition, as inclination-angle (theta) of the said holding | maintenance nail | claw 7, it can be set as 25-50 degrees, for example.

  Further, a lower portion of the back portion 21 which is the holding claw 7 is formed on the circular arc surface 27. Accordingly, as shown in FIGS. 4 to 5, since the holding claw 7 is supported in an inclined manner, when the toilet paper P is raised from below on the arc surface 27 of the holding claw 7, the outside of the paper P is removed. When the peripheral edge comes into contact with the arcuate surface 27, a component force that moves the holding claw 7 slightly obliquely forward acts and turns the holding claw 7 toward the opening 5 while keeping the paper P along the holding claw 7. Then, when the holding portion 20 of the holding claw 7 enters the core portion Pa of the paper P, the holding claw 7 can be smoothly inserted into the core portion Pa of the paper P from an oblique direction. Thereby, attachment of the paper P can be performed easily. Further, when the paper P is loaded in the reverse direction, the holding pawl 7 is moved obliquely forward when the core portion Pa contacts the arc surface 27 of the holding pawl 7 by pulling the paper P forward. The component force works, and the holding claw 7 can be rotated toward the opening 5 to smoothly take out the paper P.

  In the present embodiment, the opening is inclined and opened, but there is no need to incline as long as the inclined holding claw can be inserted into the opening. Further, the lower portion of the back portion 21 of the holding claw 7 is formed on the arc surface 27. However, when the paper P is loaded and removed, the arc surface 27 particularly has a shape that exerts a component force that moves the holding claw 7 obliquely forward. Even if it is not, it can also be made into smooth inclined surfaces other than a circular arc surface, for example, a mountain-shaped surface. Furthermore, in this embodiment, the holder main body is formed in a U-shape, but in the present invention, the present invention is not limited to this, and the holder main body is formed in an E-shape to hold two toilet papers. It can also be made possible.
