Abstract

PROBLEM TO BE SOLVED: To provide a holder allowing a user to perform a cutting operation of roll paper with one hand.SOLUTION: Roll paper 40 is fitted in a holder 1a, an elastic body 21 is provided at a side part 11 of a cover 8a including a cutting blade 9 and a weight 12, and the elastic body has a pressure-contact friction part 20a coming into pressure contact with an inner wall 4 of a transverse member 3. Rotational pulldown force 14 of the cover including the weight part that resists against pullup force in cutting the paper and frictional resistance force of the pressure-contact friction part 20a doubly function to retain the cover at a stationary cuttable position. One left paper part 41 is adapted to expose 43 from the cutting blade 9 when the roll paper is fitted, and the exposed paper is pulled out 44 and cut by a cutting length. When the left paper part is pulled out, a right paper part 42 is simultaneously exposed 43. This configuration can alternately pull out and cut the left and right paper parts.

Description

A holder for attaching a roll paper, which is mainly provided in toilets and toilets, etc.
The present invention relates to a holder capable of performing a series of use operations of a paper using this holder with one hand.

A conventional holder includes a lateral member that forms a holder main body on a side portion of the roll paper that supports the roll paper;
A rear member forming a holder-main body connected to the rear portion of the horizontal member;
A cover for covering the roll paper is disposed above the roll paper mounting portion;
The cover has a cutting blade across the width direction of the front end, and the rear part of the cover is pivotally supported by the horizontal member or the rear member, and the pivotally supported part is supported (with the pivotal part as a fulcrum). A cover in which the front portion of the cover is freely rotatable (circular arc rotation), and the cover covering the roll is freely rotatable. The raising and lowering of the cover and the paper cutting are performed. In some cases, the cover tip is pressed against the roll paper with one hand so that the cover is not lifted up and pulled out with the other hand. Use both hands to cut.

In order to prevent the cover tip from being easily pulled up when the paper is cut, a cover such as a metal is provided on the cover to prevent the cover from being pulled up.

Also, with a holder that is operated with one hand, a part of the paper is sandwiched at a position on the rear side of the cutting blade, and tension is applied to the paper so that the cutting blade easily bites into the paper and is cut. Was.

The general conventional holder described above needs to be operated with both hands.
In the case of a cover with a heavy weight, such as a weight, a large pressing force (contact force) that presses the roll paper due to the weight of the cover is generated, so that friction when the paper is pulled out is generated. It may be difficult to pull out the paper by force.
In another embodiment of the holder operated with one hand, there is a holder that makes the cutting blade easy to bite by giving tension to the paper.
However, with this method, the structure is complicated, and it is difficult to attach and detach the roll paper, and it seems that the operability is lacking in simplicity.

  The present invention is intended to solve such a conventional problem, and the cover has a constant weight so that the tip of the cover always abuts against the roll paper during use. Therefore, it is possible to suppress the downward pulling force of the cover due to its own weight, and to reduce the pressing force (contact force) to the roll paper, which is necessary for operation with only one hand. It is an object of the present invention to provide a holder for taking out the paper and cutting the paper.

In order to achieve the above object, the holder of the present invention suppresses the pressing force (abutting force) of the cover and prevents the cover from being pulled up, so that the cover separated from the pivot portion is provided. A friction portion is provided between the side portion side of the first member and the inner wall portion of the horizontal member, and the friction portion is a pressure-contact friction portion that is in a pressure-contact state that is slidable and rotatable, or a magnet that is magnetically magnetized so as to be slidable and rotatable. A frictional force having both an adhesion friction part or the pressure contact friction part and the magnetic adhesion friction part is generated.
And the moment effect | action which enlarges the deterrent with which a cover is pulled up, so that the said friction part leaves | separates from the said pivot part will work. (Refer to FIGS. 1 to 4)

In order to obtain a constant frictional force, the pressure-contact friction part has a structure having an elastic body in which at least one of the cover and the lateral member is elastic (having elasticity), or is detachable or It is made of a resilient material, for example, a soft material having a large frictional force such as rubber, or a spring. (See Figs. 1, 2, and 3)

  The magnetized friction part is provided with a magnet on at least one of the cover and the horizontal member and a ferromagnetic body on the other, and the strength of the frictional force is obtained by the magnitude of the magnetic force to obtain a constant frictional force. Can be adjusted. (See Figure 4)

  The frictional force of the friction part is slightly smaller than the rotational pulling-down force due to the weight of the cover, and the front end of the cover is always kept in pressure contact (contact) state with the roll paper. I'm trying.

  When friction is generated between the cover and the holder main body (horizontal member) and the downward pulling force of the cover is suppressed, the contact portion between the front end of the cover and the roll paper The pressing force (abutting force) can be reduced, and when the paper is pulled out, the frictional resistance of the contact portion between the cover and the roll paper is reduced, and the paper can be easily pulled out.

Further, in contrast to the cover itself provided with a weighted portion or the like with an increased rotational pulling force, the frictional force of the frictional portion (rotation inhibiting force) is made smaller than the rotational pulling force. The cover is always brought into contact (placed) on the roll paper with a constant pressing force.

  Further, the downward pulling force applied downward from the cover itself facing the cover being lifted and the resistance force due to friction act double when the paper is cut, thereby reliably preventing the cover from being lifted. be able to.
