Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention mainly relates to a roll holder device for holding a roll of a sheet-like material such as a paper towel or toilet paper.

2. Description of the Related Art Conventionally, the holder has been held by penetrating the inside of the core with a rod or by inserting the holding plate of the hook as a slide mechanism from both sides of the core and holding it.

The problem to be solved by the invention is that a large amount of force is applied to the rod holding portion and the slide mechanism, which makes the device heavy because of the need for a durable structure, and it requires both hands when replacing, which makes the work troublesome. In addition, when the roll is pulled out, rotation starts and inertia rolls to rotate the roll more than necessary to unwind, but it is difficult to arbitrarily brake the rotation with one hand and the roll may sag.

An object of the present invention is to provide a device capable of easily and reliably holding a roll and braking rotation.

MEANS FOR SOLVING THE PROBLEMS The roll holder according to the present invention is disposed in the mounting portion in such a manner that at least one of the roll holders expands relative to the other,
A pair of holding plates that rotatably hold the rolls between each other and a swingingly arranged portion of the holding plate in a manner of appearing and disappearing in the moving range of the expanding and moving holding plate. A swing arm that restrains the expanding movement of the holding plate when it is occupied on the moving area, and a swing arm that is held at the tip of the swing arm and is moved toward and away from the peripheral surface of the roll by the swing of the swing arm. And a roll retainer that is occupy between the unrolled portion of the roll and the circumferential surface of the roll and is pressed against the circumferential surface of the roll by the action of tension applied to the unrolled portion of the roll. .

Function In the present invention, the roll 6 is held together with the swing arm 2 while restraining the holding plate 3 holding the roll 6 from both ends so that the holding plate 3 does not open. The brake is applied to the rotation of the roll so that a simple and lightweight device performs two functions.

Embodiment FIG. 1 to FIG. 3 show an embodiment of a roll holder according to the present invention.

The holder illustrated here holds a roll 6 of paper towel, and is equipped with a mounting portion 5. Mounting part 5
Is formed in a rectangular shape, and hinge members 9 and 10 are attached to both upper and lower edges thereof, respectively.

Further, this holder is provided with holding plates 3 and 3 at both ends of the mounting portion 5, respectively. The holding plates 3 and 3 are the second
As shown in the figure, each of the protrusions 3 is provided at the center of the base end.
a and 3a are provided, and columnar hooks 4 and 4 are provided at corresponding portions on the tip end side. And these holding plates 3 and 3 are respectively the protrusion parts 3a and 3a.
The hinge members 9 and 10 are held so as to be capable of expanding with respect to each other (in the direction of arrow A in FIG. 1).

On the other hand, the holder is provided with swing arms 2 and 2 at both ends of a hinge member 9 attached to the upper edge side of the mounting portion 5, respectively. The swing arms 2 and 2 are provided with a roll presser 1 between their respective front end portions, and are hinged via individual base end portions in the vertical direction (arrow B in the figure).
Direction) is pivotally supported so that it can be swung in the direction.

The holder configured as described above is used for the mounting portion 5
It is used by attaching it to a wall with a rubber suction cup or the like (not shown) disposed on the back surface of the.

To attach the roll 6 such as a paper towel to this, first
As shown in the drawing, the pair of swing arms 2 and 2 are swung upward to raise the roll presser 1 and open the holding plate 3 on one side. Then, the holding plate 3 may be closed while keeping the roll 6 in an appropriate position, and the roll 6 may be locked between the hooks 4 and 4 of the holding plates 3 and 3 to lower the roll presser 1. At that time, the roll presser 1 comes into contact with the surface of the roll 6 and stops. At this time, the pair of swing arms 2 and 2 occupy the outer surfaces of the holding plates 3 and 3, respectively, and restrain outward movement of these holding plates 3 and 3. The unwinding portion 6'of the paper towel is pulled out onto the roll holder 1 to complete the preparation. When using this, pull the paper out to an arbitrary length because the roll can be freely rotated and unwound by pulling the paper horizontally. Since the rotation of the roll is braked as the edge of the paper is lowered, the paper is cut along the edge of the roll presser 1 or the perforation when the paper is lowered to an appropriate angle and pulled strongly. The diameter of the roll becomes smaller according to the amount used, and the swing arm 2 moves, but the holding plate 3 is always kept within the range of its rotation angle.
When the holding plate is designed so as to restrain the opening of the sheet, it has two functions as described above. As shown in Fig. 4,
A flexible cover plate 7 is attached to the hinge member 9 to cover the upper part of the peripheral surface of the roll 6 and the roll presser 1, and a regulating member such as a rubber cloth or a magnet is provided at a corresponding portion of the roll presser 1 and the cover plate 7. If the unwinding portion 6'of the roll 6 is passed between the regulating members 8 and 8 by attaching 8,8, when the unwinding portion 6'is cut, its end is returned to the device by a shock. Since it can be prevented from being lost, it becomes a more convenient device.

Further, in the above embodiment, one holding plate 3 is expanded and moved when the roll 6 is held, but both holding plates 3 and 3 may be expanded and moved.

Effect of the Invention The present invention can be widely applied to rolls of wrapping paper and industrial paper as well as paper towels, and since it is lightweight, it can be attached to any place. This makes it possible to perform the dashi cutting operation quickly with one hand, and the effect is that it is easy and economical to manufacture.
