Roll paper removal mechanism

The present invention relates to a roll paper take-out mechanism that facilitates taking out paper from roll paper such as toilet paper.

Conventionally, toilet paper and kitchen paper are known as typical roll paper. And the holder of a toilet paper is well known as what hold | maintains such a roll paper. The toilet paper holder is provided with a cut plate that covers the upper side of the roll paper. The toilet paper is pulled out with one hand, and the portion pulled out while holding the cut plate with the other hand is cut out.
However, conventional toilet paper holders are inconvenient for handicapped users. In particular, it may be difficult to find the beginning of the toilet paper drawer. In this case, by pushing or pulling the lower part of the toilet paper, the toilet paper is turned to search for the start of the drawing. However, this operation is difficult not only when the hand or finger is injured, but also when the hand is paralyzed due to the sequelae of cerebral infarction.
In order to make it easier to turn the roll of toilet paper, there is known one in which an opening is provided in a plate covering the toilet paper so that the toilet paper can be rotated from above (Patent Document 1).

A roll paper take-out mechanism comprising a plate-like member that covers the upper part of the roll paper and a friction member provided at the tip of the plate-like member, wherein the friction member is the plate. It is constituted by a member that extends in the direction of the roll paper from the shape member, and the friction member is a friction member that comes into contact with the roll paper, imparts resistance to the surface layer of the roll paper, and peels off the leading end of the roll paper A roll paper take-out mechanism is configured.

Since the roll paper take-out mechanism is configured as described in claim 1, the roll paper can be taken out easily even when hand inconvenience is present. Further, the roll paper can be taken out simply and intuitively.

Since the roll paper take-out mechanism is configured as described in claim 2, the roll paper take- out operation can be performed by a pulling operation.

Since the roll paper take-out mechanism is configured as described in claim 3, the roll paper can be taken out easily.

  The present invention constitutes a roll paper holder that is easy to rotate and pull out toilet paper, particularly toilet paper, by operation above the roll paper.

First, an example of a roll paper take-out mechanism will be described using a toilet paper holder. FIG. 1 is a view showing an installation example of a paper holder, and FIG. 2 is a perspective view of the paper holder.
The toilet shown in FIG. 1 is provided with a toilet 1 and a paper holder 2. A paper holder 2 is disposed on the side or diagonally forward of the toilet bowl 1, and a toilet paper 4 that is a roll paper is held on the paper holder 2.
The paper holder 2 is disposed at a position where the user can take out the toilet paper 4 while sitting on the toilet 1.

The paper holder 2 shown in FIGS. 1 and 2 is provided with a paper driving device 2b. In this case, toilet paper is taken out, and even a person whose hand is hurt by the paper driving device 2b can easily take out the toilet paper 4.
The paper holder 2 includes a frame 21, a support arm 22, and a cover plate 23. Here, the support arm 22 is a support member for the toilet paper 4, and the cover plate 23 is a plate-like member that covers the upper portion of the toilet paper 4.
The paper drive device 2 b is provided on the cover plate 23. The support arm 22 is attached to the frame 21 so as to be tiltable from the vertical direction to the horizontal direction, and toilet paper is inserted from below so that the toilet paper 4 can be held by the support arm 22. The cover plate 23 is rotatably attached to the frame 21 at a rear end portion thereof by a rotation shaft parallel to the axial direction of the toilet paper 4.

The paper drive device 2 b is composed of a roller 25 and a support member 24. The roller 25 is a contact tool that can contact the toilet paper. The roller 25 is rotatably supported by the support member 24 in a state where a lower portion is inserted into an opening 23 f provided in the cover plate 23. The support member 24 is rotatably attached to the rear end portion of the cover plate 23.
The roller 25 is supported by the support member 24 and can be rotated in a state of being in contact with the toilet paper 4. Since the support member 24 is rotatable with respect to the cover plate 23, the roller 25 can sufficiently come into contact with the toilet paper 4 even when the diameter becomes small in the process of using the toilet paper 4. ing.
In addition, an uneven shape is formed around the roller 25, and slippage between the roller 25 and the toilet paper 4 is suppressed. The uneven shape of the roller 25 is constituted by a rubber belt attached to the roller 25, and can be reliably driven without damaging the toilet paper 4.

Next, a more detailed structure of the paper holder will be described.
FIG. 3 is a side view of the paper holder, FIG. 4 is a view showing a rotating state of the cover plate and a drive state of the toilet paper, and FIG. 5 is a view showing a follow-up configuration of the roller to the toilet paper.
In the paper holder 2, the frame 21 fixes the rear surface, and can be fixed to a support member that can support the paper holder 2, a wall, or the like. An arm 22 is disposed at the front end of the frame 21, and the arm 22 is inserted inside the core of the toilet paper 4 to hold the toilet paper 4.
A support shaft 23 b is attached to the upper end portion of the frame 21, and this support shaft 23 b is disposed along the core direction of the toilet paper 4. The cover plate 23 is attached to the frame 21 via the support shaft 23b. As a result, the cover plate 23 is rotatably supported with respect to the frame 21.
A support shaft 24b is disposed on the upper surface of the cover plate 23 in parallel with the support shaft 23b, and a support member 24 that supports the roller 25 is attached to the cover plate 23 via the support shaft 24b. As a result, the support member 24 is rotatably supported with respect to the cover plate 23.

The cover plate 23 is configured in a substantially arc shape that is convex upward in a side view. And the front-end | tip part of the cover plate 23 contact | abuts on the peripheral surface upper part of the toilet paper 4. As shown in FIG.
The support member 24 disposed on the cover plate 23 is also configured in an arc shape along the cover plate 23 in a side view. The entire length of the support member 24 is configured to be shorter than the cover plate 23, and the rear end portion of the support member 24 is connected to the middle portion of the rear portion of the cover plate 23.

A support shaft 25b is disposed at the tip of the support member 24, and the roller 25 is pivotally supported by the support shaft 25b. The roller 25 can move downward by its own weight, and the support member 24 rotates according to the roller 25. Then, the roller 25 is pressed against the toilet paper 4 by its own weight.
Thereby, the roller 25 and the toilet paper 4 can ensure contact with a simple structure reliably. Then, the weight of the support member 24 is applied to the cover plate 23, and a part of the load applied to the cover plate 23 is applied to the peripheral surface of the toilet paper 4 at the distal end portion of the cover plate 23.

The cover plate 23 can be rotated upward together with the support member 24. The support member 24 is rotatable rearward from the cover plate 23.
Thereby, the paper holder 2 becomes a structure which can maintain the same usability as the conventional paper holder. Like the conventional toilet paper holder, the core of the toilet paper 4 is lifted upward, the core is removed, and a new toilet paper is inserted from below the paper holder 2, so that the toilet paper is replaced as before. be able to. In addition, the support arm 22 can divert the support structure of other general toilet paper.

As shown in FIG. 4, the toilet paper 4 is attached to the paper holder 2, the cover plate 23 is lowered, and the roller 25 is rotated in the front-rear direction (the left-right direction in FIG. 4) with the roller 25 in contact with the toilet paper 4. Thus, the toilet paper 4 is driven by the roller 25 and rotates in the front-rear direction.
When the upper part of the roller 25 is rotated backward, the upper part of the toilet paper 4 is rotated forward. Then, when the upper part of the roller 25 is rotated in the forward direction, the upper part of the toilet paper 4 is rotated forward. Thus, by rotating the roller 25, the toilet paper 4 can be rotated, and the toilet paper drawer can be easily found. Moreover, since there is no slip between the roller 25 and the toilet paper 4, the toilet paper 4 can be reliably pulled out according to rotation of the roller 25.
Further, since the roller 25 is disposed in a state of protruding on the cover plate 23, the operation of the roller 25 is easy, and the state in which the roller 25 is in direct contact with the toilet paper 4 is indicated by the opening 23f of the cover plate 23. Since it is visible, an intuitive operation of the roller 25 can be performed.

Next, the following mechanism for the roller 25 to follow the toilet paper 4 will be described.
The roller 25 is configured on the cover plate 23, and as shown in FIG. 5, the position of the cover plate 23 is determined by the tip of the cover plate 23 coming into contact with the toilet paper 4. For this reason, even when the diameter of the toilet paper 4 is reduced, the tip of the cover plate 23 is rotated downward to maintain contact with the toilet paper 4.
The support member 24 is rotatably attached to the cover plate 23, and a roller 25 is attached to the front portion of the support member 24. For this reason, the roller 25 also moves downward together with the cover plate 23 according to the diameter of the toilet paper 4. And even if the diameter of the toilet paper 4 becomes small, a contact can be maintained. The toilet paper 4 can always be driven regardless of the diameter of the toilet paper.

Next, the behavior of the paper drawer at the tip of the cover plate 23 will be described.
FIG. 6 is a diagram illustrating the behavior of the paper drawer at the front end of the cover plate.
By rotating the toilet paper 4 forward by the drive device 2b, the drawer portion of the toilet paper can be lifted and easily found.
As shown in FIG. 6A, the upper part of the roll of the toilet paper 4 is driven forward by the roller 25 from a state in which the tip 4 b serving as the drawer portion of the toilet paper 4 is located below the cover plate 23. Then, as shown in FIG. 6B, the front end portion 4 b appears from the cover plate 23 after the front end portion of the cover plate 23 is recessed.
The load of the cover plate 23 and the support member 24 is applied to the front end portion of the cover plate 23, and the front end portion 4b of the toilet paper 4 has a resistance force opposite to the moving direction when passing below the cover plate 23. Receive.
This resistance force is generated along the layer direction of the toilet paper 4, and the outside is strong and the inside is weak. Further, the front end 4b of the toilet paper 4 is released after being deformed inward by a load in the process of passing through the front end of the cover plate 23. Due to these influences, as shown in FIG. 6C, the front end portion 4b of the toilet paper 4 through the cover plate 23 is peeled off from the toilet paper 4 and slightly floated.
As described above, since the front end 4b of the toilet paper 4 is taken out through the front end of the cover plate 23 in the pulling direction by driving the roller 25, the front end 4b can be floated by friction with the cover plate 23 or the like. The start of drawing out the toilet paper 4 can be easily found.
That is, by using the paper holder 2, the toilet paper 4 can be easily driven and the front end portion 4 b of the toilet paper 4 can be easily taken out.
Furthermore, by attaching a member that increases the contact resistance with the toilet paper 4 to the cover plate 23, the peeling effect of the tip portion 4b from the roll is more remarkably generated, and the toilet paper 4 can be pulled out more easily. Can do. For example, a friction member can be attached to the lower surface of the front end of the cover plate 23, or an elastic member that urges the cover plate 23 against the toilet paper 4 can be attached.

Next, another configuration of the driving device in the roll paper holder will be described.
7 is a perspective view showing the roll paper holder of Example 2, FIG. 8 is a side view showing the driving device of Example 2, FIG. 9 is a diagram showing a contact state of the roll paper surface with the edge, and FIG. It is a schematic diagram which shows the drawer structure of the toilet paper front-end | tip part by an edge.
In the second embodiment, a driving device 26 is disposed on the cover plate 23 of the paper holder 2. The driving device 26 includes an upper portion 26b that protrudes to the upper surface side of the cover plate 23, a lower portion 26c that is located on the lower surface side of the cover plate 23, and a spring 26d that is connected to the rear end of the lower portion 26c. And the upper part 26b and the lower part 26c of the drive device 26 are connected via the opening groove 23c provided in the cover plate 23, and are comprised integrally.

An edge 23 d is provided on the lower surface of the front end of the cover plate 23. The edge 23d is attached to the cover plate 23, and gives a resistance force opposite to the driving direction to the surface layer of the toilet paper 4. The resistance force makes it easy to pull out the front end portion of the toilet paper 4. The edge 23d has a shape in which a plurality of triangular protrusions protruding downward are connected in a side view. In FIG. 8 and FIG. 9, the edge 23d has a shape in which the apex portions of the continuous triangles are arranged downward, and the resistance is small when the toilet paper 4 is rotated forward, and when the toilet paper 4 is rotated backward. It is comprised so that resistance may become large.
The edge 23d can be constituted by a protruding member protruding toward the toilet paper 4 on the lower surface side of the cover plate 23. The protruding member serving as the edge 23d can be configured continuously or intermittently at the front end of the cover plate 23.
In the configuration shown in FIGS. 8 and 9, the edge 23 d is provided with three protrusions having a triangular shape in a side view in the front-rear direction of the cover plate 23.
This edge 23d makes it easy to rotate the toilet paper 4 in the forward direction, and makes it difficult to rotate it backward. Further, the edge 23d is in contact with the surface layer of the toilet paper 4 to easily give friction resistance. Thereby, the drawer part of the toilet paper 4 that has passed through the edge 23d floats from the surface of the toilet paper 4 and is easily taken out.

Since the edge 23d is configured with a certain width from the tip to the rear inside the cover plate 23, the edge 23d can be brought into contact with the surface of the toilet paper 4 even when the diameter of the toilet paper 4 changes. it can.
As shown in FIG. 9, when the diameter of the toilet paper 4 is large, the edge 23 d can abut on the surface of the toilet paper 4, and even when the diameter of the toilet paper 4 is small, the edge 23 d can abut.
Further, when the diameter of the toilet paper 4 is reduced, the weight of the toilet paper 4 is reduced and the weight of the cover plate 23 causes the toilet paper 4 to move inward.
However, since the edge 23d is provided inside the cover plate 23, the surface of the toilet paper 4 can be captured by the edge 23d even in this case.

As shown in FIG. 10, the edge 23 d exhibits an effect even when the front end portion of the toilet paper is taken out. Since the edge 23d has a plurality of protrusions, a partial resistance can be applied to the surface of the toilet paper 4. As a result, the front end 4b of the toilet paper 4 can be easily pulled out.
By providing a plurality of protrusions, the contact area with the toilet paper 4 can be increased, and the resistance to the rotation direction can be improved while reducing the load applied to one place. Further, the stepped shape of the edge 23 d makes it easier for the tip end portion 4 b to peel off from the surface layer of the toilet paper 4.
As shown in FIG. 10A, when the tip 4b is introduced under the edge 23d, the tip 4b is wrinkled due to the stepped shape of the edge 23d as shown in FIG. 10B. Then, the toilet paper 4 is easily peeled off from the surface layer. Then, as shown in FIG. 10 (c), when the edge 23 d is passed, the tip portion 4 b is peeled from the surface layer of the toilet paper 4 by being pulled toward the side opposite to the driving direction by the resistance force due to the contact of the edge 23 d. Thereby, it becomes easy to take out the front-end | tip part 4b.
Further, the contact force of the edge 23d generates a resistance force in the direction opposite to the driving direction, so that it acts as a brake for the toilet paper 4 and can prevent the toilet paper 4 from rotating excessively.

FIG. 11 is a diagram showing another configuration of the friction member.
In FIG. 11, (a) and (b) show a friction member 231 having a triangular side cross-sectional shape. The friction member 231 is attached to the front lower side surface of the cover plate 23, and the front side angle is standing at the contact portion of the friction member 231 with the toilet paper 4, and the rear side angle is lying down. ing. Thereby, compared with the rotation to the rear side of the toilet paper 4, the rotation to the front side is configured easily.
In FIG. 11, (c) shows the friction member 232 comprised by the rod-shaped member which has one rounded side surface. The friction member 232 has a shape protruding from the lower surface of the cover plate 23 toward the toilet paper 4, and the side surface facing the toilet paper 4 is rounded. Since the cover plate 23 is rotatably supported on the back side (rear end side), and the friction member 232 is provided at the front portion, the toilet paper 4 with which the friction member 232 abuts can be rotated forward. It is configured to make it difficult to turn to the rear side.
In FIG. 11, (d) shows the friction member 233 having an elastic member extending obliquely downward in the front direction. The friction member 233 is provided with an elastic member that extends obliquely downward to the front, and this elastic member makes it difficult for the toilet paper 4 to turn to the rear side than to turn to the front side. Yes. Further, since the elastic member is configured to be deformable, it is possible to suppress an excessive force from being applied to the toilet paper 4.
In FIG. 11, (e) shows the friction member 234 in which the needle-like body is extended obliquely forward and downward with respect to the toilet paper 4 at the contact portion with the toilet paper 4. The friction member 234 is configured by a brush, and the friction member 234 is configured to make it difficult to rotate the toilet paper 4 to the rear side compared to the front side.
In FIG. 11, (f) shows the friction member 235 extended toward the toilet paper 4. The friction member 235 is made of a rubber spatula, and the friction member 235 makes the toilet paper 4 difficult to turn to the rear side than to turn to the front side. Further, since the elastic member is configured to be deformable, it is possible to suppress an excessive force from being applied to the toilet paper 4.

Next, the operation of the driving device 26 will be described with reference to FIG. FIG. 12 is a diagram illustrating a driving configuration of toilet paper by the driving device.
The lower portion 26c of the drive device 26 has a front portion that follows the shape of the lower surface of the cover plate 23, and a rear portion that extends obliquely downward. Thereby, the drive device 26 can be tilted forward and the front portion can be directed downward. Furthermore, the drive device 26 is slidable along the opening groove 23c in a tilted state.
As a result, as shown in FIG. 12A, when the driving device 26 is pulled to the front from the state where the driving device 26 is in the natural state and is positioned at the rear end of the opening groove 23c, FIG. As shown, the driving device 26 is tilted and the lower front end is brought into contact with the toilet paper 4.
And as shown in FIG.12 (c), if the drive device 26 is made to slide ahead, the toilet paper 4 can be rotated to the front side. This operation can be naturally performed by pulling a knob formed on the upper portion of the driving device 26.

  When the driving device 26 is released, the driving device 26 returns to the rear position of the opening groove 23c by the spring 26d as shown in FIG. Since the spring 26d is connected to the portion extending downward and rearward of the driving device 26, the front end of the driving device 26 is positioned upward by the restoring force of the spring 26d (the lower end portion is the lower surface of the cover plate 23). In a state of abutting on the back). For this reason, when the drive device 26 moves rearward, the tip is not in contact with the toilet paper 4, and the toilet paper 4 is not rotated rearward.

  Thus, the toilet paper 4 can be rotated forward by pulling the driving device 26 forward. Further, the toilet paper 4 is rotated by the operation of pulling the driving device 26, and a part of the force when pulling the driving device 26 applies a load to the tip of the cover plate 23. Therefore, the toilet passed under the tip of the cover plate 23. The leading end of the paper 4 floats from the peripheral surface of the toilet paper 4 and is easily pulled out.

Next, another configuration of the roller support in the roll paper holder will be described.
13A and 13B are diagrams showing a roll paper holder according to Example 3, in which FIG. 13A is a side view and FIG. 13B is a front view.
In FIG. 13, a roller 25 for driving toilet paper is rotatably supported by an arm 24c. The arm 24c supports the roller 25 at the front end and is rotatably supported by the support member 24d at the rear end. The support member 24 d is provided on the rear portion on the cover plate 23. Thereby, the roller 25 can be supported with an easy configuration.

Next, a configuration in which the roller is formed in a cylindrical shape and supported by the cover plate 23 will be described.
14A and 14B are diagrams showing a roll paper holder in which a roller is configured in a cylindrical shape, in which FIG. 14A is a side view and FIG. 14B is a perspective view.
The roller 25 is formed in a cylindrical shape and has a hollow center part. Here, a support member 23h is provided horizontally across the opening 23f of the cover plate 23, and a collar 25d is mounted on the support member 23h. And the roller 25 is arrange | positioned on the outer side of the collar 25d, and the inner surface collar 25d of the roller 25 contacts.
Thereby, since the cover plate 23 also serves as a support member for the roller 25, the roll paper holder can be configured in a compact manner.

Next, the structure which uses a roll paper holder for a desktop is demonstrated.
FIG. 15 is a perspective view showing a configuration of a self-supporting roll paper holder.
In the fourth embodiment, the frame 201 of the roll paper holder 200 extends sufficiently lower than the toilet paper 4, and a leg 202 extending forward is connected to the lower portion of the frame 201. By configuring the frame 201 of the roll paper holder 200 in this manner, the roll paper holder in which the toilet paper 4 can be easily taken out using the roller 25 can be placed on a table or the like.
