Description

  The present invention relates to a roll paper holder that holds paper so that the paper can be pulled out. The paper can be pulled out with one hand, and at the same time, a holding portion can be secured at the paper cutting end so that the paper can be easily pulled out. It is related with the roll paper holder formed in.

In a conventional roll paper holder, a roll-shaped toilet paper is rotatably held, and the toilet paper is covered with a cover whose end is a cutting blade. In use, lift the paper cover, etc. to pick up the edge of the toilet paper and pull it out, then hold the cover with the other hand and pull the edge along the position where the edge is the cutting blade. In addition, it is a method of cutting toilet paper.
The thing which was devised to operate this with one hand is patent document 1 and patent document 2, and it is mainly made to apply "the force of pulling the paper and applying the principle of the lever to change the force to hold the paper directly". However, in many cases, the force of pulling the paper during cutting often exceeds the pressing force of the roll part, and the paper often breaks while rotating, and often does not cut cleanly.

On the other hand, as a method of securing the gripping part and facilitating the drawing of the paper, Patent Document 3 as a method of sliding and extruding the instrument, or securing the holding part by providing a difference between the paper pressing part and the cutting position There are Patent Literature 4 and Patent Literature 5 as methods for doing this, but these also open the lid and search for the gripping portion again when the paper is cut off in the middle, and there is a concern about frequent work.
Apart from this, there is Patent Document 6 as an object devised with a focus on a desktop type, but design considerations are required to make it a desktop type or a portable type.

  In the conventional toilet paper holder as described above, it is necessary to use both hands to cut the toilet paper, which is inconvenient for a person with a physical disability. In many cases, the end of the toilet paper is not cut at the intended part and rotates while remaining in close contact with the outer periphery of the roll, and there is an inconvenience that the end of the toilet paper is difficult to find and pick when next used. It was. The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a paper holder and a paper cutting device that can be cut with only one hand and can easily pick up the end of toilet paper.

  In order to solve the above problems, many of the past inventions tried to apply the principle of the lever by pulling the paper to directly press the paper and replace it with the slip resistance force. The main means is to change the paper to the pressing release force by applying the principle of the lever. This uses the natural movements of the hands and arms when pulling the paper to use the paper holder to press or release the paper, pulls the paper smoothly when it is pulled, and pulls it when cutting the paper. The roll paper body is securely locked without rotating so that the paper can be easily cut. In addition, after the paper is cut, a gripping portion is secured at the front end of the paper to prepare for the next use.

The roll paper holder of the present invention can always be picked and pulled out from the end of the roll paper, and the drawn paper can be cut with one hand. Moreover, since the previous user has not touched the paper gripping portion, it is hygienic.
The roll paper holder of the present invention is a box body, which has a simple structure with a flap mechanism and a pressing friction body of the lid body, can be easily made into a desktop holder, and the lid top plate is shaken. Because it does not move, it is convenient for handicapped people such as attaching the main body to a wall etc. to use it for mobile phones and back accessories, installing a counter attached to the main body, functioning as a handrail to support the body High nature.
The roll paper holder of the present invention can be used with or without a paper core and is good for the environment because it does not generate paper core dust. It is a paper cutting mechanism that does not depend on paper quality and can be installed in a storage box for kitchen paper or wrapping sheets. Moreover, the winding direction is not limited with respect to the loading of the roll paper.
By constructing a material other than the basic structure of the present invention with a flexible material (cloth, vinyl, etc.), it is excellent in weight reduction and portability, and a new application can be expected for toilet paper as a substitute for tissue paper for nursing care sites and pets. Moreover, the degree of freedom of design is high by changing the box to wood, mineral, synthetic resin, metal material, etc.

  A feature of the roll paper holder according to the present invention is that “the paper that is normally locked is changed to a pressing release force by applying the lever principle” by using a flap mechanism. That is, the natural movement of the hands and arms when using toilet paper is used to press or release the paper, and the paper slides out smoothly when the paper is pulled out, and the paper is securely locked when cut. Embodiments of the present invention will be described below with reference to the drawings.

(A) The loaded roll paper tip 1e passes through the guide plate projection 2e, passes through the tip of the paper flip-up plate 3c, and hangs down from the gap of the cutting tool mounting plate 5, and presses the friction body 4b at a position 1b along the way. Are sandwiched between the pressing protrusions 3b by the pressing force of the movable pressure contact plate spring 3h. When the roll paper tip 1e is picked and pulled slightly, the tip of the paper jumping plate 3c formed of an elastic material is bent to the vicinity of the pressure contact plate tip 3e. (Fig. 3) (Fig. 4)
(B) Since the pressure plate main body 3a is a movable pressure plate formed of an elastic material stronger than the paper jumping plate 3c and integrated with the pressing protrusion 3b, the pressure plate main body 3a rotates about the movable pressure plate rotary shaft 3d. In this case, the paper pressure contact position 1b sandwiched by the pressing force of the movable pressure contact plate spring 3h is released, and the paper pulling resistance is caused by the guide plate protrusion 2e, the guide plate end 2f, and the pressure plate front end 3e rolling the paper's own weight. It becomes the resultant force of resistance. The force resisting the pressing force of the movable pressing plate spring 3h acting on the pressing protrusion 3b is proportional to the distance from the movable pressing plate rotating shaft 3d to the pressing plate front end 3e. That is, the lever principle is applied to the movable pressure contact plate. (FIG. 5) In the state immediately before cutting the paper, the paper refracting portion A1a, the paper pressing portion 1b, the paper refracting portion B1c, and the paper cutting position 1d are arranged on a substantially straight line. It is characterized in that it is sandwiched by the pressing force of the pressure plate spring 3h and the paper starts to slide out. (Fig. 6)
(C) As described above, the pulling force is concentrated on the paper cutting position 1d because the paper is sandwiched between the pressing friction body 4b and the pressing protrusion 3b by the pressing force of the movable pressure contact plate spring 3h and the sliding of the paper is restricted. Although it becomes a cutting force, the movement of the hand and the arm moves in a direction parallel to the cutting teeth 5a, that is, in the lateral direction so as to reduce the cutting resistance. Therefore, the paper skid prevention protrusion 5b is attached for the purpose of preventing this. (Fig. 7)
The finally cut paper tip 1e hangs down depending on the weight of the paper itself, but depending on the cutting conditions, the fibers at the paper tip 1e may be entangled and left behind on the cutting teeth 5a. The paper jumping plate 3c intended to peel it off is jumped upward and separation is performed. At the same time, the paper is sandwiched in the gap between the tip of the paper flip-up plate 3c and the cutting tool mounting plate 5, so that paper curling is suppressed and the paper hangs vertically and orderly. (Figure 3)

When the toilet paper body 1 is loaded in the roll paper holder of the present invention, the lid body 4a is opened by rotating the lid body rotating shaft 4c, and then the flap mechanism is rotated by the guide plate mounting arm rotating shaft 2g for loading. It becomes necessary to secure the necessary openings (FIG. 8). FIG. 10 (FIG. 11) shows a mechanism that completes this in one operation, that is, the flap mechanism rotates in conjunction with opening of the lid 4a to secure the loading opening.
When the lid 4a is fully opened, the flap mechanism is stationary at the position of the stay rotating shaft B9k because the pressing force is transmitted from the arm 9c to the stay 9e by the spring force of the arm spring 9d (FIG. 10). Subsequently, when the operation of closing the lid 4a is performed, the arm 9c is rotated around the arm rotation shaft 9h by the return force of the arm spring, and the flap mechanism is rotated while the arm is rotating about the guide plate mounting arm rotation shaft 2g. Stop with arm 9c at stopper 9f. When the lid is further closed, the guide roller 9g slides along the guide rail groove 9b formed in the guide rail 9a and stops at a fixed position of the lid (FIG. 11). In addition, when the lid 4 is closed, it is semi-fixed by the magnetic force of the latch mechanism or permanent magnet, etc., and even when the paper cutting force is applied (Fig. 7), it is securely and securely held so that it does not open accidentally. is doing.

  The cover 4a, the cutting tool mounting plate 5 and the handle 4f, which are rotatably mounted on the roll paper holder of the present invention, are assembled and molded integrally with resin or the like, or a flexible material other than the basic structure (fabric, It is made into a desktop type or portable type (Fig. 12) by being made of vinyl, etc., and used as a substitute for tissue paper.

  Conventionally, roll paper holders are mostly fixed and used exclusively in toilets, but the present invention is simple and compact in mechanism, and is made of a flexible material (fabric, vinyl, etc.) other than the desktop structure and basic structure. By constructing it, weight reduction and portability can be achieved, and new applications can be expected for toilet paper as a substitute for tissue paper for nursing care sites and pets. It can also be used as a kitchen paper holder or wrap sheet holder by widening the holder width, and can be used as a tape cutter by narrowing the width.
