Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cutting device for rolled sheets such as toilet paper. More specifically, the present invention relates to a rolled sheet cutting device that allows the rolled sheet to be easily cut with one hand and that makes it easy to grip the cut end of the sheet.

[Prior art] For example, a cutting device for a rolled sheet of torrent paper has a structure in which a presser plate is placed on the roll paper attached to the shaft of a holder, and the paper is cut by the tip of the presser plate. These are common.

[Problems to be solved by the invention] However, the above-mentioned conventional cutting device had the following problems.

(a) The presser plate is simply placed on the roll paper, so if you lift the paper upwards when cutting the paper, the presser plate will also spring upwards. In order to prevent this, it is necessary to hold the presser plate with the other hand, and it is necessary to use both hands when cutting the paper. For this reason, there are inconveniences such as, for example, a person with a disability in one hand cannot use the roll paper.

(b) When cutting the paper, the cut edge overlaps the edge of the presser plate, and if the edge of the presser plate has a saw-like cutting blade, the cut edge of the paper may not adhere to the cutting blade. After putting it away, you have to turn the roll paper and take out the cut end each time you use it next time, which is a hassle.

etc.

[Means for solving the problems] The means of the present invention taken to solve the above problems are as follows.

A first idea includes a frame provided with a sheet guide part, and a notch part formed at the leading edge of the sheet guide part; a notch part corresponding to the notch part formed therein;
a rocking guide whose base end is pivotally connected to the frame, and which is located on the sheet guide part side in a normal state and holds the sheet so that it can be drawn out between the base end; a cutting member pivotally connected between the tip end and the base end of the swinging guide, the tip end being pivotally connected to the control member, and a cutting blade provided between the tip end and the base end; 1. A control member for cutting a rolled sheet, comprising: a control member having a portion pivotally attached to a distal end portion of the cutting member and a base end pivotally attached to a frame;

The second invention is such that the frame of the cutting device of the first invention is further provided with a holding member for the rolled sheet.

A third aspect of the invention includes: a frame provided with a sheet guide portion, and a notch portion formed at the leading edge of the sheet guide portion; a notch portion corresponding to the notch portion formed therein;
a rocking guide whose base end is pivotally connected to the frame, and which is located on the sheet guide part side in a normal state and holds the sheet so that it can be drawn out between the base end; The swing guide is pivotally connected between the tip and the base end, and the tip engages with a control groove formed in the side plate provided on the frame. a cutting member provided with a cutting blade; and the control groove is configured to rotate the cutting member from the sheet guide side and stop the cutting member in the sheet cutting state. This is a cutting device.

A fourth invention is one in which the frame of the cutting device of the third invention is further provided with a holding member for a rolled sheet.

An example of the rolled sheet is toilet paper.

The structure of the holding portion for the rolled sheet is not particularly limited as long as the rolled sheet can be attached thereto. Further, when the cutting device is used by being attached to a conventional paper holder, there are cases where there is no need to newly provide a holding section for the rolled sheet.

The tip of the swinging guide acts in a direction away from the cutting blade due to gravity and spring force. For this reason,
After cutting the sheet, the tip of the swinging guide pushes the sheet toward the sheet guide part, and separates the cutting part (next take-out knob part) of the sheet from the cutting blade to prevent it from sticking.

The notch of the swinging guide corresponds to the notch of the sheet guide, and the sandwiched sheet is exposed at that portion and can be easily pinched.

The cutting member is interlocked with a swing guide body that rotates by pulling up the sheet.

Note that, in order to avoid danger, it is optional to provide a guard member in a part of the frame to accommodate the cutting blade of the cutting member.

The cutting device can be placed in a general room and used as a decorative paper supply and accessory case, a simple dressing table, or as a paper holder in a washroom.

[Example] The present invention will be described in more detail based on an example shown in the drawings.

FIG. 1 is a partially cutaway perspective view showing the first embodiment;
FIG. 2 is an explanatory diagram showing the movement of important parts when cutting a sheet.

The rolled sheet cutting device A has an upright piano overall shape and has the appearance of an ornament. The cutting device A includes a frame 1 with an open top. A lid 11 is pivotally attached to the rear of the upper opening of the frame 1. A mirror 12 is attached to the back side of the lid 11, and by opening the lid 11 and standing it upright, it can be used as a mirror stand. A hook portion 13 projects slightly below the inside of the upper edge of the opening of the frame 1, and a storage box 14 is placed on the hook portion 13. This storage box 1
4 can store small items such as combs.

On the inside of both side walls 40, 40a of the frame 1,
A mounting groove 15 for a roll sheet is formed. The mounting groove 15 has an open upper end and a U-shaped stop portion 151 at the lower end so as not to hinder the rotation of the holder core 101. The holder core 101 is horizontally suspended on the stop part 151, and a roll sheet is attached thereto.

The holder core 101 in this embodiment has an electronic music box built therein, and when a sheet is pulled out, the rotation of the holder core 101 is sensed and the electronic music box is activated. A seat guide section 2 is provided on the front side of the frame 1 and has a cutout section 20 formed in the center thereof. A roll sheet introduction port 21 is provided on the rear side of the sheet guide section 2.

A swing guide plate 3 is swingably attached to the seat guide section 2 via a hinge section 31 (see FIG. 2). A notch 30 having the same shape as the sheet guide portion 2 is formed at the center of the tip edge of the swing guide plate 3 . This notch 30 and the notch 20 form a cut 4 of the roll sheet. A piano key-shaped pattern 32 is provided on both sides of the front end of the swing guide plate 3.
is applied. Further, at the rear of the pattern 32, a blade plate 5 is pivotally attached via a hinge 51 so as to be swingable.

Among the tip portions of the blade plate 5, the cutting blade 5 to be described later
2 is not provided with the cutting blade 5.
It is curved and formed to protrude more forward than 2. The tips of the both side portions 50 are connected to the upper end of the control plate 6 by a pin 60, and are provided with a hinge portion 61. The control plate 6 has substantially the same shape as the blade plate 5 except that the lower portion thereof is curved forward. The lower end of the control plate 6 is attached to the seat guide section 2 on the front side of the blade plate 5 via a hinge section 62.

A saw blade-shaped cutting blade 52 is provided near the hinge 51 from the tip of the blade plate 5 and is bent forward at a substantially right angle, excluding both side portions 50. Further, a notch 53 is formed in the center of the blade plate 5, leaving the cutting blade 52 intact. Reference numeral 22 is a finger insertion hole that makes it easy to lead out the sheet. Reference numeral 17 denotes a guard member provided on the front surface of the main body, and is provided protruding slightly above the position corresponding to the cutting blade 52. The cutting blade 52 is normally housed in the lower part of this guard member 17, so there is no danger. That's what I do.

(Operation) The operation of this embodiment will be explained with reference to FIGS. 1 and 2.

First, a roll-shaped sheet P (for example, a roll-shaped toilet paper) is attached to the holder core 101, and the stop part 15 of the mounting groove 15 of the frame 1 is
Attach it to 1. Insert the tip of the sheet P into the inlet 21
and hold it between the upper surface of the sheet guide section 2 and the swing guide plate 3. (See Figure 2) When the tip of the sheet P in the opening 4 is pinched and pulled out by the required amount, the holder core 101 rotates, the built-in electronic music box is activated, and music is played.

Hinge part 31, hinge part 51, hinge part 6
1. Since the four parts of the hinge part 62 can be rotated,
When the seat P is pulled upward, the swing guide plate 3
Rotate in the lifting direction. On the other hand, the control plate 6 and the blade plate 5 rotate toward the swing guide plate 3, that is, toward the seat P. (See FIG. 2) When the sheet P is further pulled up, the swing guide plate 3 rotates, and the sheet P comes into contact with the cutting blade 52 of the blade plate 5 that has rotated in the opposite direction and is cut.

At this time, the blade plate 5 is pressed against the swing guide plate 3 and comes into close contact with it, and the hinge portion 51 becomes a dead center. As a result, each operating portion is supported at three points by the hinges 61, 62, and 31. A force is applied to the blade plate 5 in the direction of the arrow Y, which is the cutting direction, and a force is applied to the swinging guide plate 3 connected by the hinge portion 51 in the direction of the arrow Y, causing the blade plate 5 and the swinging guide plate 3 to The adhesion state remains unchanged. Therefore, the cutting blade 52 cannot be rotated in the opposite direction, and the sheet P is reliably cut. (See FIG. 2) When the sheet P is cut, the swing guide plate 3 rotates downward by its own weight and returns to its original state with the sheet P sandwiched between it and the sheet guide section 2. As a result, the blade plate 5 and the control plate 6 also return to their original states.

The leading end of the sheet P is exposed at the opening 4 and can be easily removed, which is convenient for the next use.

FIG. 3 is a schematic side view showing the second embodiment. The rolled sheet cutting device A is formed in the shape of a normal toilet paper holder. The structure and operation of the cutting mechanism section B provided at the tip of the frame 1 are almost the same as those in the first embodiment, so detailed explanations will be omitted.

FIG. 4 is a schematic side view showing the third embodiment. A rolled sheet cutting device A according to this embodiment can be used by being installed at the tip of a presser plate of a toilet paper holder. In this embodiment, a spring 40 for drawing the cutting device toward the toilet paper P is interposed between the side plate 41 holding the toilet paper P and the frame 1. Except for the mechanism related to the holding member for the rolled sheet, the structure and operation of the cutting mechanism section B provided at the tip of the frame 1 are almost the same as those in the first embodiment, so detailed explanations will be omitted.

FIG. 5 is a schematic side view showing the fourth embodiment. The roll-shaped sheet cutting device A according to this embodiment can be used by being installed on the holding side plate 41 of the toilet paper P of a conventional toilet paper cutting device. Various known means can be used for attaching it to the holding side plate 41. The structure and operation of the cutting mechanism section B provided at the tip of the frame 1 are almost the same as those in the first embodiment, except for the mechanism related to the holding member for the rolled sheet, and therefore the details will be omitted.

FIG. 6 is a schematic explanation of the fifth embodiment showing the movement of the mechanism of the movable part.

The structure of the cutting device according to this embodiment is that there is no control plate 6 in the first embodiment, and instead, both side plates holding the toilet paper P corresponding to the side walls 40, 40a provided on the frame 1 or The structure is generally the same as that shown in the first embodiment except that a control groove 42 is formed on one side, and detailed illustrations are omitted.

A control groove 42 is formed in one or both of the holding side plates 41. The control groove 42 is formed in an arc shape. One end 42 a of both ends of the control groove 42 is a position where the swing guide plate 3 is located on the sheet guide section 2 side and holds the sheet so as to be drawn out between the swing guide plate 3 and the sheet guide section 2 . The other end 42b is a position where the blade plate 5 rotates to come into contact with and cut the toilet paper P.

Of the blade plate 5, both side parts 50 on which the cutting blade 52 is not provided are curved and protruded forward. An engagement pin 43 is fixed to the tip thereof and engaged with the control groove 42 .

When the sheet P is pulled up from the normal state, the swing guide plate 3 rotates, and as a result, the blade plate 5 moves inside the control groove 42 at one end 4.
2a toward the other end 42b. When the sheet P reaches the other end 42b, as shown in FIG.
The force for pulling up is in the X direction, and the sheet P is cut for the same reason as in the first embodiment.

In addition, in the second to fifth embodiments, the same or equivalent parts as in the first embodiment are denoted by the same reference numerals.

Further, the present invention is not limited to the illustrated embodiment, and among the cutting devices according to the fifth embodiment,
Various modifications are possible within the scope of the utility model registration claims, such as the possibility of omitting the mechanism related to the holding member for the rolled sheet.

[Effect of the idea] The present invention has the following effects.

(a) When the sheet comes into contact with the cutting blade during cutting,
The blade plate is pressed against the swing guide plate and comes into close contact with it, and each operating part is supported at three points, and the blade plate stops. Therefore, since the cutting blade stops and does not run away backwards, the sheet can be easily and reliably cut with one hand.

(b) The swinging guide plate acts in a direction away from the cutting blade, and when cutting, applies a force to pull up the sheet to move it in the direction of the cutting blade, and after cutting, it moves in a direction away from the cutting blade. Therefore, the cut end of the sheet guided by the swing guide plate is always away from the cutting blade except when cutting.

In addition, a notch is provided in the swing guide plate and the sheet guide portion that hold the sheet, and a portion of the leading end of the sheet is exposed from the notch, making it easy to pick up the sheet. Therefore, in combination with the fact that the cut end of the sheet is separated from the cutting blade, it is convenient because there is no need to turn the rolled sheet each time to take out the cut end, as in the past, when the sheet is used next time.
