JP3120968U - Non-contact roll paper holder with paper tip out function - Google Patents

Abstract

PROBLEM TO BE SOLVED: It is a problem that it takes time psychologically and efficiently because it touches a holder that it does not want to touch as is well known, raises and lowers the cover, takes out the leading edge of the paper and cuts it to the required length.
To solve the problem by cutting out the paper and automatically leading out the paper, the ratchet claw is operated by lifting the cover to lock and cut the paper shaft. Then, the lock is released with the cover, and the paper tip is pushed out by the weight of the cover using a one-way clutch. As a result, the paper can be cut without contact with the holder and with one touch.

Description

  The present invention takes into account hygiene and psychological aspects and cuts out paper with emphasis on workability.

  In general, toilets are hygienic and psychologically hesitating because they touch the holder, but in reality, the left hand lifts the cover to take out the tip of the paper cut with a cutter, and the right hand has the required length The workability is poor because the paper is pulled out and pressed again with the left hand to cut the paper.

  Roll paper is limited to toilets due to its poor workability and is rarely used in other places.

  In particular, public girls' toilets are often crowded, but the poor workability of taking out paper is not considered to be a factor.

The issues to solve the problem are as follows.
1 Workability is poor and takes time to cut the required roll paper.
2 Cannot be used without contact with the holder.
3 Roll paper has been used exclusively for toilets.

  This plan uses the force to lift the cover up with paper to cut the paper, locks and cuts the paper shaft, and then uses the force to return to the original by the weight of the cover. This is a combination of directional clutches.

  Since the paper is cut while pulling, the blade part that cuts the paper must be appropriate.

  The paper shaft and roll paper must be rotated at the same time so that the leading edge of the paper cannot be put out. Therefore, the paper shaft and the roll paper must be fixed or simultaneously rotated by friction and the paper can be easily replaced.

  As described above, the paper is cut to a desired length by holding only the protruding portion of the paper with the right hand or the left hand, and the paper can be cut out with one touch without any contact with the holder.

  As shown in FIG. 1, the main body 1 has two main shafts as the best mode, one of which is a paper shaft 2 and a paper gear 3 and a ratchet wheel 4 fixed thereto. There is a cover gear 8 via an intermediate gear 5, and a one-way clutch 7 is incorporated into the cover shaft 6. The cover A12 is press-fitted into the cover shaft, and the cover B13 is slid onto the cover shaft. The one-way clutch 7 rotates relative to FIG. 1 so that the cover shaft 6 rotates independently of the cover gear 8 when rotated clockwise, but the cover gear 8 is forced to rotate when rotated counterclockwise. A directional clutch 7 is incorporated. When viewed from the side of the cover gear 8 incorporated in this way, when the gear rotates counterclockwise, the rotation is not transmitted to the cover shaft.

  When the paper drawn out to the desired length is lifted with cover A cover B with paper to cut it, the ratchet pawl 10 is supported by a ratchet spring 11 as shown by a two-dot chain line in FIG. The ratchet wheel 4 is locked and the paper shaft stops. The upper stopper 15 is also locked at this position. Then, the paper is pulled with a cutting edge of the cover A cover B. When it is cut, the cover B13 slides on the shaft and returns to its original weight due to its own weight. The ratchet pawl 10 is pushed up to unlock the solid line, and the cover A12 rotates counterclockwise to its original position due to its own weight. Both the cover shaft 6 and the cover gear rotate counterclockwise. As a result, the paper gear 3 also rotates counterclockwise via the intermediate gear, thereby leading out the paper. The stopper 14 is a stopper in which each cover returns. The length of the leading edge is determined by the rotation angle of the cover and the gear tooth ratio.

  In the present plan, the paper shaft 2 and the roll paper 23 must move in the same way and the paper must be exchanged. Therefore, the paper shaft 2 and the paper holder are jointed as shown in FIG. A joint pin 17 is struck on the other end of the paper shaft, and a groove that fits the joint pin 17 is cut in the holder A18 (see FIG. 4). The extension spring 21 enters the holder 19 and the holder A enters it. A guide pin 20 is struck on the holder A, while a long groove is cut on the holder B19 to provide a guide for expansion and contraction when the paper is replaced, and the guide pin 20 is used to transmit the rotation. A necessary number of leaf springs 22 are attached to the circumference, and the rotation is transmitted by friction. The bearing 16 is for stabilizing the paper shaft 2.

  The blade portions attached to the tips of the cover 12 and the cover 13 in FIG. 5 are formed by using a helicopter formed as a blade when a steel plate is cut off by a cutting machine and chamfering the opposite surfaces.

  The paper holder is basically the same as that generally used, but the joint and leaf spring are added.

Claims (1)

  A roll paper holder characterized by being cut with a blade on the end face of the paper cover while the paper shaft is locked by tensioning the paper shaft by lifting the cover with the roll paper drawn to a predetermined length. After the paper is cut, the cover is unlocked by its own weight, returns to its original position, and pushes out the paper. Paper can be cut with one touch without contact with the vapor holder.
