Description

The present invention relates to a toilet paper system.

Toilet paper is usually supplied to toilets and the like as a toilet paper system in which toilet paper wound around a core is set in a toilet paper picker having a toilet paper support plate.
Conventionally, rolled toilet paper is held in place by either passing a core rod in a toilet paper picker through its cylindrical core, or by an insert structure in which protruding posts are inserted from both sides, and the toilet paper is used by grasping the tip of the toilet paper and pulling out an appropriate amount, but since the tip of the toilet paper is hidden inside the cut cover of the toilet paper picker, it can be inconvenient to pick it out.

To solve this inconvenience, one possible solution would be to rotate the toilet paper roll an appropriate amount, allowing the tip of the toilet paper to hang down and providing an amount that is easy to pick up.

Incidentally, Patent Document 1 describes providing a protrusion on the surface of an insertion member provided in the toilet paper picker so as to come into contact with the inner surface of the cylindrical toilet paper.

Technical Literature

Utility Model Publication No. 57-68695

The method of Patent Document 1 aims to eliminate any play between the inner diameter surface of the toilet paper core and the catching part, thereby reducing the vibration noise when the toilet paper is pulled out. However, even if you try to rotate the toilet paper using the protrusion, it tends to slip, and is not suitable for rotating the toilet paper an appropriate amount after cutting it off, and for stably securing the tip of the toilet paper at a length that is easy to pick up.

The present invention is intended to solve the above problems, and provides a toilet paper system that has a hooking means on the inside of the core of the toilet paper, which reliably rotates the toilet paper and stably secures the tip of the toilet paper at a length that is easy to pick up.

The core material of the present invention is a cylindrical body that serves as a core for winding up toilet paper into a roll, and commercially available products are usually made of a paper tube.

The insertion member of the present invention is a member that is inserted into the tubular core of a roll of toilet paper from one side or separately from both sides to support and rotate the toilet paper.

The rotating means of the present invention is a rotating means provided in the insertion member, which rotates the insertion member in the axial direction. The rotating means may include a motor, a gear, a rotation control, or a power source, and may be provided inside or outside the insertion member.

The hooking means of the present invention is a means for rotating the toilet paper by a rotating means, and at the opposing surface between the core material and the insertion member, elastic bodies protrude in several places on the circumference of at least one of the surfaces of the core material and the insertion member, pressing against the opposing surface to hook by frictional force, or by providing bumps and grooves on each other to allow the toilet paper to hook and rotate.
The unevenness is achieved by having protrusions on opposing sides of the core material and the insertion member catch on each other, or by having the protrusions enter and catch within a recess or cutout portion, thereby allowing rotation.

The spring material portion of the present invention is a hooking means using a spring, and a deformable metal or resin plate or rod can be used.

The protrusion of the present invention is a hooking means using a protrusion, and can be made of elastomers such as rubber or resin. Also, if the core material is a deformable material such as a thin cardboard tube, a hard material with an acute tip can be used.

The capturing member of the present invention is provided between the core material of the toilet paper and the insertion member, and captures the inner surface of the core material via a spring material portion or an elastic protruding portion.

The lantern spring of the present invention has an overall cylindrical shape like a lantern with a bulging center on the side, with multiple frameworks arranged axially on the side and bundled together at both ends of the tube, and the frameworks are the spring material part that has spring properties.

The rotary switch of the present invention is a power switch that rotates and stops the rotation of the insertion member, and can be used without any particular limitation as a touch sensor, a membrane push button, etc. As for the installation location, it is more convenient to install it on the cut cover or toilet paper support plate, etc.

The core catcher of the present invention is provided to catch used toilet paper that has come off the insert member when replacing the toilet paper, and is provided to protrude from the lower part of the toilet paper support plate.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
Figure 1 shows a schematic diagram of the toilet paper system of the present invention. Figure 1(a) shows a method of inserting an insert member 4 into a core 2 of a toilet paper 1 from one side, and Figure 1(b) shows a method of inserting an insert member 4 into a core 2 of a toilet paper 1 from both sides.
The toilet paper 1 is wound into a roll around a cylindrical core 2. The axial cross section of the toilet paper 1 is U-shaped, and the toilet paper 1 is sandwiched from both sides by a toilet paper support plate 3. An insert member 4 is inserted into the core 2, and the end of its shaft core 5 is engaged with the toilet paper support plate 3 to hold the toilet paper 1. The insert member 4 rotates around the shaft core 5 by a rotating means 6. Accordingly, the toilet paper 1 and its core 2 are provided with a hooking means 7 for hooking the insert member 4 and the toilet paper 1 to each other, thereby allowing them to rotate.
In Fig. 1(a), the shaft 5 extends and is engaged on both sides of the opposing inner surfaces of the toilet paper support plate 3, but a bearing or the like may be provided at the engaging portion to rotate at this portion. In Fig. 1(b), the shaft 5 extends and is engaged on one side of the opposing inner surfaces of the toilet paper support plate 3, but the insert member 4 on the other side does not necessarily have to be provided with a hooking means 7 or rotate, but at least it may be made of a material with a reduced surface friction coefficient or have an embossed structure with a small contact area so that the contacting core material 2 can rotate easily.

Fig. 2 shows another schematic diagram of the toilet paper system of the present invention. It shows the case where the rotating means 6 is inside the insert member 4. Fig. 2(a) shows a method of inserting the insert member 4 into the core 2 from one side, and Figs. 2(b) and (c) show a method of inserting the insert member 4 from both sides. Fig. 2(c) shows the case where the insert member 4 is connected to the toilet paper support plate 3 via a spring hinge 8. By providing this structure, the insert member 4 can rotate to the upper side at the rear side of the toilet paper support plate 3 in Fig. 2(c), making it easier to attach and detach the toilet paper 1 from the insert member 4.
Also, to prevent the insertion member 4 from rotating and hitting the toilet paper support plate 3, the portion of the toilet paper support plate 3 that will come into contact with the toilet paper support plate 3 may be hollowed out.

Figure 3 shows another schematic diagram of the toilet paper system of the present invention, specifically showing the hooking means. Figures 3(a) and 3(b) show the case where the rotating means 6 is outside the insert member 4, and Figure 3(c) shows the case where the rotating means 6 is inside the insert member 4.
3(a) and 3(c) show a method using a spring member 9, and FIG. 3(b) shows a method using a protruding portion 10.
The spring material portion 9 can be a thin plate or wire with a circular or elliptical arc, and the protrusion can be a rubber elastic molded body or cut body, etc. In either case, they are provided circumferentially or intermittently on the outer surface of the insert member 4, and the overall maximum outer diameter is made slightly larger than the inner diameter of the core material 2 of the toilet paper 1, pressing against the inner surface of the core material 2 to catch it by frictional force.

Fig. 4 shows another schematic diagram of the toilet paper system of the present invention. It shows a method using a capture member 11 as the hooking means 7. Fig. 4(a) shows a method using a spring member 9, and Fig. 4(b) shows a method using a protrusion 10. The capture member 11 is usually inserted and fixed into at least one hole of the toilet paper 1 with the core material 2, and then the insert member 4 is inserted into the hole of the capture member 11. The role of the capture member 11 is to adjust the gap between the inner diameter of the core material 2 and the outer diameter of the insert member 4, and to provide irregularities such as protrusions 12, dents or notches 13 instead when the inner surface of the core material 2 is a smooth surface, as shown in Fig. 5 or Fig. 6.

Fig. 5 shows another schematic diagram of the toilet paper system of the present invention. It shows a method of providing protrusions 12 on the inner surface of the capture member 11 and the outer surface of the insertion member 4 as the hooking means 7. The protrusions 12 are provided at one or more places on each side, and if multiple protrusions are provided around the circumference of either side, hooking can be performed smoothly.

6 shows another schematic diagram of the toilet paper system of the present invention. As the hooking means 7, a method of providing a protrusion 12 on the outer surface of the insert member 4 and a recess or notch 12 on the capture member 11 is shown. The protrusions 12 and the recesses or notches 13 are provided in pairs, and the number of the recesses or notches 13 must be at least greater than the number of the protrusions 12.

Fig. 7 shows a cross section of the hooking means portion of Fig. 6. Fig. 7(a) shows an example in which a protrusion 12 is provided on the insertion member 4 and a recess 13a is provided on the capture member 11, Fig. 7(b) shows a recess 13a on the insertion member 4 and a protrusion 12 on the capture member 11, and Fig. 7(c) shows an example in which the outer cross-sectional shape of the insertion member 4 and the inner cross-sectional shape of the capture member 11 are similar to each other and have a protrusion 12 and a recess 13a, so that the protrusion 12 fits into the recess 13a and gets hooked. Fig. 7(d) shows an example in which the insertion member 4 and the capture member 11 are provided with protrusions 12, so that they come into contact with each other and get hooked during rotation.

Fig. 8 shows another schematic diagram of the toilet paper system of the present invention. It shows a method of providing protrusions 12 on the inner surface of the core material 2 and the outer surface of the insert member 4 as the hooking means 7, and shows an example in which they come into contact and hook during rotation. The protrusions 12 provided on the inner surface of the core material 2 may be formed by cutting the core material 2 into a U-shape and pushing it out to the inner surface.
