Description

  The present invention relates to a toilet paper holder for roll-shaped toilet paper, and more particularly to a toilet paper holder that can be easily pulled out to a required length and cut with one hand.

  A conventional general toilet paper holder is configured such that a rod body is inserted into the core tube of a toilet paper roll body, the roll body is rotatably held, and the toilet paper drawn from the roll body is placed above the roll body. Is cut by a cutter formed at the tip of the upper cover covering the cover. With this type of toilet paper holder, when cutting the toilet paper to the required length, the upper cover is not lifted and the hand holding the toilet paper is used to prevent the roll body from slipping. You must hold the top cover with another hand. That is, both hands are required for cutting toilet paper, and it is difficult for people who have physical disabilities or who have one hand blocked for some reason.

Various proposals for making it possible to easily use toilet paper with one hand have been made (for example, Patent Documents 1 to 3). However, these conventional proposals have taken measures to prevent the upper cover from being lifted, but have not taken enough measures to prevent the toilet paper roll body from slipping. My body slipped and I could not cut the toilet paper well.

  The present invention has been made in view of the above circumstances, and it is possible to completely prevent the cutter unit from lifting when the toilet paper is cut and the roll of the toilet paper from slipping, and reliably and easily remove the toilet paper with one hand. It is an object to provide a toilet paper holder that can be cut.

  In order to solve the above problems, the present invention has the following configuration. That is, the toilet paper holder according to claim 1 is attached to a bracket fixed to the wall surface of the structure, and the bracket so as to be rotatable in the forward rotation direction and non-rotatable in the reverse rotation direction via the reverse rotation prevention mechanism. The direction in which the interval between the rotating body capable of holding the roll body by matching the rotation center axis and the axis of the toilet paper roll body and the outer peripheral surface of the roll body held by the rotating body expands or contracts And a rotating body having a cutter portion for cutting toilet paper drawn from the roll body at the front end portion. The rotating body has a center of rotation of the rotating body. A plurality of recesses are formed on the circumference centered on the shaft, and the rotating body is normally disengaged from the recesses, and the rotating body is an outer peripheral surface of the roll body. When pivoted engaging member for restricting the rotation of the rotating body engaged with the concave portion is characterized in that it is provided to the side spacing is enlarged.

  According to this configuration, when the toilet paper pulled out from the roll body is cut, the engaging member of the rotating body is engaged with the concave portion of the rotating body in conjunction with the cutting operation, thereby restricting the rotation of the rotating body. At the same time, the rotation of the roll body is restricted. For this reason, when the toilet paper is cut, the cutter part is lifted up, and the roll body of the toilet paper does not idle, and the toilet paper can be cut surely and easily with one hand.

  The toilet paper holder according to claim 2 is characterized in that, in addition to the contents of claim 1, the anti-reverse mechanism is centered on the rotation center axis of the rotating body on either the bracket or the rotating body. A radial engaging groove is provided, and on the other hand, it is possible to engage with the engaging groove, and when the rotating body rotates in the forward rotation direction, it can escape from the engaging groove, and the rotating body in the reverse rotation direction. In the case of rotation, an engagement claw that cannot escape from the engagement groove is provided.

  This prevents the rotating body from rotating in the direction of taking up the toilet paper (reverse direction) due to the reaction at the end of the cutting operation or the foreign object coming into contact with the roll body. The position is maintained, and the end of the toilet paper can be easily grasped at the next use.

  Furthermore, in addition to the contents of claim 1 or 2, the toilet paper holder according to claim 3 is such that the rotation center axis of the rotating body and the rotation center axis of the rotating body are horizontal, and the rotating body is toilet paper. The upper cover covering the upper part of the roll body was also used.

  Thus, the number of parts can be reduced by adopting a configuration in which the rotating body also serves as the upper cover. Further, since the engaging member returns to the normal position by the weight of the upper cover at the end of the cutting operation, it is not necessary to provide a biasing means for returning the engaging member to the normal position.

  In the toilet paper holder according to the present invention, the rotation of the rotating body is restricted as described above, and the idle roll of the toilet paper roll body is completely prevented, so that the toilet paper can be easily pulled out and cut with one hand. be able to. Therefore, this toilet paper holder is suitable for installation in a toilet of a house where a person with a physical disability lives or a facility used by an unspecified number of people.

  The present invention is applied to a toilet paper holder that is used by being attached to a vertical wall surface, thereby facilitating attachment / detachment and easy cutting of the toilet paper.

  Hereinafter, embodiments shown in the drawings will be described. 1 is a front view of a toilet paper holder showing a state in which a roll body of toilet paper is mounted, FIG. 2 is a side view thereof, and FIG. 3 is an SS cross-sectional view thereof. The toilet paper holder 1 includes a bracket 2 fixed to a vertical wall surface, an anti-reverse boss 3 provided integrally with the bracket, and can rotate in the forward direction with respect to the anti-reverse boss and in the reverse direction. The rotary body 4 is configured to be non-rotatable, and the upper cover 5 is a rotary body that is rotatably supported by the bracket 2.

  The bracket 2 includes a back plate 2a fixed to a wall surface with screws or the like, and a side plate 2b protruding forward from one side end of the back plate. A cover support shaft 6 is horizontally provided between the upper ends of the left and right ends of the back plate 2a, and the base portion of the upper cover 5 is rotatably supported by the cover support shaft 6.

  As shown in FIG. 4, the reverse rotation preventing boss 3 has a stepped shape having a small diameter portion 3a and a large diameter portion 3b, and a countersunk screw 7 inserted from the outside into the side plate 2b of the bracket is provided in the small diameter portion. By being screwed to the end face of 3a, it is fixedly attached to the side plate 2b so that the central axis is horizontal. In the illustrated embodiment, since the reverse rotation-preventing boss 3 is attached by a single countersunk screw 7 located on the central axis, the countersunk screw 7 is not loosened by the rotation of the rotating body 4 described later. The countersunk screw 7 is preferably provided so as to be tightened when rotated in the forward rotation direction of the rotating body 4.

  Further, a plurality of engagement grooves 8,... Are formed at equal intervals radially from the intermediate portion to the outer peripheral edge of the step surface 3c of the small diameter portion 3a and the large diameter portion 3b. These engaging grooves 8,... Constitute a rotating body reverse rotation prevention mechanism with engaging claws 9,.

  As shown in FIG. 5, the rotating body 4 includes a cylindrical portion 4a and a disc portion 4b, and a large-diameter portion 3b of a reverse rotation-preventing boss is slidably fitted inside the cylindrical portion 4a. Thereby, the rotating body 4 is rotatable with respect to the bracket 2 and the reverse rotation preventing boss 3. The cylindrical portion 4a is configured to externally fit the core tube of the toilet paper roll body 21 and hold the roll body integrally. Since the rotating body 4 is cantilevered by the bracket 2, the roll body 21 can be attached to and detached from the cylindrical portion 4a from the right side in FIG. The roll body 21 can be easily attached and detached, and can be easily performed with one hand.

  Further, the disk portion 4b is provided with engagement claws 9,... Corresponding to the engagement grooves 8,. As shown in FIG. 6, the engaging claw 9 has a cross-sectional shape bent at the center in the width direction, and one corner 9a in the width direction is prevented from reversing more than the facing surface 4c of the stepped surface 3c. It protrudes to the side of the boss 3 for use. The pair of surfaces constituting the corner portion 9a are a gently inclined surface 9b having a gentle inclination with respect to the facing surface 4c and a steeply inclined surface 9c having a sharp inclination with respect to the facing surface 4c. Since the engaging claw 9 is relatively thin, it has flexibility in the thickness direction.

  Normally, the engaging claw 9 is in a state in which the corner 9a is fitted in the engaging groove 8 (state shown in FIG. 6). In this state, when a force in the forward rotation direction A is applied to the rotating body 4, the engaging claw 9 gradually bends upward in FIG. 6 in accordance with the inclination of the gently inclined surface 9b, thereby engaging the corner portion 9a. Since it rides out of the joint groove 8, the rotating body 4 rotates smoothly in the forward rotation direction A. On the other hand, when a force in the reverse rotation direction B is applied to the rotator 4, the steeply inclined surface 9c engages with the edge of the engagement groove 8, and the corner 9a cannot run over the engagement groove 8. The rotating body 4 cannot rotate. That is, the rotating body 4 can rotate in the normal rotation direction A with respect to the reverse rotation prevention boss 3, but cannot rotate in the reverse rotation direction B.

  Further, a guide groove 10 that guides an engaging member 12 to be described later is formed in the disc portion 4b. The guide groove 10 has an annular shape centered on the rotation center axis of the rotating body 4, and a plurality of recesses 10a,... Are formed at equal intervals on the outer peripheral side.

  The upper cover 5 is provided so as to cover the upper part of the toilet paper roll body 21 held by the cylindrical portion 4 a of the rotating body 4, and a base portion is rotatably supported by a cover support shaft 6 provided on the bracket 2. . The main body portion 5a of the upper cover has a flat rear portion and a front portion that is curved along the outer shape of the roll body. Then, the arcuate portion 5b protruding forward is formed following the curved front portion of the main body, and further, the cutter is bent obliquely downward at the tip of the arcuate portion and the tip is sharply formed in a side view. Part 5c is formed.

  A support plate 11 is provided to hang from one end of the main body 5a, and an engagement member 12 that is loosely fitted in the guide groove 10 is attached to the lower end of the support plate 11. In normal times, as shown in FIG. 2, the engaging member 12 is in a position where it abuts against the inner peripheral wall of the guide groove 10, and the weight of the upper cover 5 is supported by the support plate 11 and the engaging member 12.

  As shown in FIG. 7, when the toilet paper 20 is pulled out from the roll body 21, the upper cover 5 is slightly lifted by the tension of the toilet paper 20, but the engaging member 12 is engaged with the recess 10 a of the guide groove 10. Thus, the rotating body 4 and the roll body 21 held by the rotating body 4 can freely rotate in the normal rotation direction A.

  When the toilet paper 20 is pulled out by an appropriate length and the pulled toilet paper 20 is pulled upward to cut the toilet paper 20, the upper cover 5 lifted by the toilet paper 20 is rotated upward as shown in FIG. Thus, the engaging member 12 engages with the recess 10 a of the guide groove 10. Thereby, the upper cover 5 does not rotate any more and the rotation of the rotating body 4 and the roll body 21 is restricted. When the toilet paper 20 is further pulled upward, the toilet paper 20 is cut by the cutter unit 5c. Thus, in conjunction with the cutting operation, the rotation of the upper cover 5 and the rotation of the rotating body 4 are automatically restricted, so that the toilet paper 20 can be cut reliably and easily with only one hand.

  When the toilet paper 20 is no longer supported by the cutting, the upper cover 5 rotates to its original position by its own weight. Since the cutter unit 5c is located away from the outer peripheral surface of the roll body 21, as shown in FIG. 2, the end of the cut toilet paper 20 is hung from the roll body 21, and the next toilet paper is used. Sometimes it is easy to grab paper.

  In the embodiment, the toilet paper holder used by attaching to the vertical wall surface is shown in which the rotation center axis of the rotation body and the rotation center axis of the rotation body are horizontal, but the rotation center axis of the rotation body and the rotation of the rotation body are shown. You may provide so that a center axis may become perpendicular | vertical or diagonal. Moreover, you may make it install a toilet paper holder on a floor surface or a horizontal stand.

It is a front view which shows the toilet paper holder with which the toilet paper was mounted | worn. It is the side view. It is SS sectional drawing in FIG. It is (a) front sectional drawing of the boss for reverse rotation prevention, and (b) side view. It is (a) front sectional drawing of a rotary body, and (b) side view. It is sectional drawing of an engaging groove and an engaging claw. It is a side view of the toilet paper holder which shows the state at the time of paper drawer.
