Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic toilet paper changing device.

(Prior Art) Conventionally, replacing toilet paper has been troublesome. In particular, in places other than the home, such as department store toilets that are used by an unspecified number of people, cleaners are always careful to remove used paper towels and replace them, and many paper towels are prepared in advance in the toilets. There was a drawback that if you left it there, it could be stolen.

(Problems to be Solved by the Invention) Therefore, the present invention eliminates the above-mentioned drawbacks and provides an automatic toilet paper replacement device that can extremely easily replace used paper and prevent theft. It is.

(Means for Solving the Problems) Hereinafter, an embodiment of the present invention will be described with reference to the drawings. A vertically elongated casing body 1 that accommodates a large number of paper rolls A is provided, and a portion near the bottom of the casing body 1 is provided. In addition to receiving paper rolls in use,
A lower roll holder 2 is provided to prevent removal, and on both sides near the bottom of the casing body 1,
Holes 2 are provided respectively, and the holes 2 are elastically biased so as to fit into the respective shaft holes B of the paper roll A in use under normal conditions, and the respective shafts are moved to the outside by the operation of the replacement lever 3 at the time of replacement. A hole receiver 4 is loosely fitted, and the shaft hole receiver 4 is provided at one end of an L-shaped rod 4a formed at an obtuse angle. The part is located inside the casing, and a roller 4b is provided at the other end, and the roller is attached to the exchange lever 3 integrally with respect to the center of the hole 2.
It slides into sliding contact with the slide face 3a having an eccentric arc, and one end of two interlocking rods 5, 5 is pivotally supported on the replacement lever 3, and the other end of these two interlocking rods is Located at the top of paper roll A,
A pivot point is attached to the paper roll holder 6, which normally holds the waiting paper roll A', and when replacing it, drops the waiting paper roll A' downward and further holds the paper roll A'' waiting at the top. It is made up of things that support it.

The paper roll holder 6 has a structure where the bottom part can be split into two, and is normally closed and holds the waiting paper roll A', and when replacing the paper roll, the bottom part is split into two by the operation of the replacement lever 3. It is opened via the interlocking rods 5, 5 of the book, and allows the paper roll A' waiting to fall downward, and the side part abuts at the top to further prevent the paper roll A'' waiting at the top from falling. be.

(Function) Next, to explain the function of the present invention, when the paper roll A in use is finished, when the replacement lever 3 is pulled downward, the L-shaped rod 4a provided with the shaft hole receiver 4 is removed. The roller 4b at the end is regulated by an eccentric arc-shaped slide face 3a provided integrally with the exchange lever 3, and the shaft hole receiver 4 is regulated by the paper roll A.
As a result, the shaft of the used paper roll A falls downward through the gap in the lower roll holder 2, and at the same time, the upper roll holder 7 disengages from the interlocking rods 6, 6.
The bottom part opens by moving upwards, and the waiting paper roll is opened.
A' is dropped onto the lower roll, and the paper roll A', which is waiting at the top, is further prevented from falling.

Then, when the replacement lever 3 is returned upward, the shaft hole receiver 4 located outward from the casing body 1 moves together with the replacement lever 3, and the surface of the slide face 3a becomes gentler. It is loosely fitted into the original position, that is, the shaft hole B of the paper roll A, and holds the paper roll to be used.

In this way, when a paper roll is used up, it is replaced with a new paper roll by repeating this operation one after another.

(Effects of the Invention) According to the present invention, by pulling the exchange lever 3 for a large number of stored toilet paper rolls, the shaft tube of the used paper rolls is dropped downward, and the waiting paper rolls are completely removed. It can be easily installed in sequence, and even if someone tries to steal the paper roll, the bottom roll 2 is there and cannot be pulled out, and if the paper roll supply opening of the casing body 1 is locked, there is no chance of the paper roll being stolen. However, it has extremely beneficial effects.
