A small hole into which 80 is inserted is formed. As shown in FIG. 3, a small hole into which the lower end 81 of the torsion coil spring 8 is inserted is also formed on the bottom plate 50 side of the mandrel receiver 5.

The support rod 71 is a columnar member integrally formed with the cylindrical portion 70. Due to the safety mechanism 9, the support rod 71 has a base 71A integrated with the cylindrical portion 70, and It is divided into a moving part 71B. An elongated protrusion 71a that engages with the positioning portion 60a of the holder main body 1 is formed at an end of the rotating portion 71B.

As shown in FIG. 1, the torsion coil spring 8 is used when the support rod 71 is horizontally rotated forward about the cylindrical portion 70 for the attachment and detachment of the paper roll R (hereinafter referred to as the mandrel 7). This position is referred to as a paper attaching / detaching position a), and the support rod 71 is returned to a position where the protrusion 71a engages with the positioning portion 60a of the mandrel guide 6 (hereinafter, this position of the mandrel 7 is referred to as a paper use position b). Thus, the mandrel 7 is given an elastic force. This torsion coil spring 8
As shown in FIG. 3, the mandrel 5 is attached around the support portion 51 of the mandrel receiver 5. Even when the both ends 80 and 81 are engaged with the mandrel receiver 5 and the mandrel 7 and the mandrel 7 is in the paper use position b, It has a function of pressing the projection 71 a of the support rod 71 toward the mandrel guide 6.

When the mandrel 7 is in a cantilevered state (for example, at the paper attaching / detaching position A), a downward load is applied to the supporting rod 71 of the mandrel 7, and the safety end 9 of the mandrel 7 is supported. When a moment force equal to or more than a certain value acts on the side (the cylinder portion 70 side), the support rod 71 is bent, and the rotating portion 71B on the free end side is rotated downward, and a large moment is applied to the cylinder portion 70 side. This is to prevent the force from acting. As shown in FIGS. 4 and 5, the safety mechanism 9 has one end fixed to the rotating portion 71B of the support rod 71 and the other end inserted into a long hole 71b of the base 71A.

A is formed slightly smaller than the diameter of the long hole 71b, and when one end side is positioned in the long hole 71b, the base 71A of the support rod 71 and the rotating portion 71B are aligned. Positioning. The groove 92 is formed on the support pin 91 side with substantially the same size as the diameter of the long hole 71b, and the end face side of the base 71A is formed to have a width gradually smaller than the diameter of the connecting rod 90. An elastic piece 93 is formed around the groove 92 of the base 71A having a smaller width than the connecting rod 90.

The elastic piece 93 is provided on the rotating portion 7 of the support rod 71.
When a downward load acts on the 1B side and a moment force of a certain value or more acts on the cylindrical portion 70 side, the groove 92 is elastically deformed so as to expand, and the connecting rod 90 is rotated downward,
Even when a constant upward load is applied to the rotating portion 71B, the groove 92 is elastically deformed so as to expand the groove 92, and has a function of positioning the connecting rod 90 in the long hole 71b of the base 71A. In order to facilitate the upward movement of the connecting rod 90, the groove 92 is formed diagonally so that the opposing end surface side extends downward.

Next, the toilet paper holder H
Will be described. First, mandrel guide 6
The supporting portion 61 and the fixing portion 62 are inserted into the supporting holes 14c of the holder main body 1, the projections 62a are engaged with the locking portions of the holder main body 1, and the pair of mandrel guides 6 are attached to the holder main body 1. Subsequently, after the torsion coil spring 8 is set in the cylindrical portion 70 of the mandrel 7, the mandrel receiver 5 is set in the cylindrical portion 70.
The lower end 81 of the torsion coil spring 8 is inserted.
Is positioned in the recess of the mandrel receiver 5. Then, with the two sets of the mandrel 7 and the torsion coil spring 8 set in the mandrel receiver 5, the pair of support portions 51 of the mandrel receiver 5 are inserted into the support holes 13 c of the holder body 1, and the protrusions 52 a
Is engaged with the locking portion 13f of the holder body 1. As a result, the mandrel 7 is rotatably supported by the support portion 51 of the mandrel receiver 5 in a state where the protrusion 71 a side of the support rod 71 is pressed toward the mandrel guide 6 by the torsion coil spring 8.

Next, the support portions 40, 41 of the cutter 4
Is inserted into the support holes 13a and 14a of the holder main body 1, and the rear side of the cutter 4 is rotatably supported by the holder main body 1. In this case, a vertical movement preventing device is attached around the support portion 41 so that the support portion 41 of the cutter 4 does not fall out of the support hole 13a of the holder body 1. Subsequently, the temporary fixing block 3 is attached to the holder main body 1 so that the locking pins 30 protrude outward, and the hook portions 22 of the shelf plate 2 are inserted into the fixing holes 11a of the holder main body 1, and the shelf When the plate 2 is mounted on the upper plate portion 11 of the holder main body 1, the assembling work of the toilet paper holder H is completed. Then, the holder body 1 is placed on a wall or the like in the toilet.
By screwing a screw or the like through the mounting holes 12a and 12b, the toilet paper holder H can be installed in the toilet. After the holder main body 1 is attached to a wall surface or the like, the shelf plate 2 can be attached to and detached from the holder main body 1.

Next, the toilet paper holder H
The procedure for attaching the paper roll R to the printer will be described.
First, the locking pin 30 of the temporary fixing block 3 is inserted into the protruding hole 1.
After pushing the front side of the cutter 4 upward while pushing it into the 3b and 14b, the locking pin 30 is again
, And the cutter 4 is temporarily fixed to the upper side of the holder body 1 as shown in FIG. Subsequently, the support rod 71 side of the mandrel 7 is rotated around the cylindrical part 70 side to the paper attaching / detaching position A in the front while resisting the elastic force of the torsion coil spring 8, and then becomes cantilevered. A paper roll R is mounted on the mandrel 7 from the free end side of the support rod 71 via a mandrel R1. And the support rod 7
When the support rod 71 is released with the paper roll R sufficiently supported by the mandrel 1, the mandrel 7 is rotated by the elastic force of the torsion coil spring 8 until the protrusion 71 a abuts the positioning part 60 a of the mandrel guide 6. Move.

In this state, when the projection 71a of the mandrel 7 is pushed into the positioning portion 60a side, the projection 71a is slightly curved and passes through the guide recess E1 of the positioning portion 60a.
The mandrel 7 is moved to the positioning recess E2, and is positioned at the paper use position B. Subsequently, the front side of the cutter 4 is pushed down while the locking pin 30 of the temporary fixing block 3 is raised and lowered, and the cut portion 42 of the cutter 4 is supported on the paper roll R. It can be used. That is, by pulling the end of the paper roll R downward and rotating the paper roll R around the mandrel 7, a desired amount of paper can be fed from the paper roll R. Is cut by the cutter 4, so that the fed paper can be used.

On the other hand, for mounting the paper roll R,
When the mandrel 7 is rotated to the paper mounting position A and a downward load is applied to the support rod 71 side of the mandrel 7 in any way, the support end of the mandrel 7 in a cantilever state (the cylindrical portion 7).
A large moment force acts on the 0) side. However, since the support rod 71 is provided with the safety mechanism 9 for avoiding a large moment force, even if a downward load is applied to the support rod 71, the safety mechanism 9 allows the mandrel 7 to be supported.
The moment force exceeding a certain value does not act on.

That is, when a moment force exceeding a certain value acts on the support end (cylinder portion 70) side of the mandrel 7, the safety mechanism 9
Elastic piece 93 is elastically deformed so as to open to both sides, and the connecting rod 9
Since 0 rotates downward about the support pin 91, the rotating portion 71B of the support rod 71 moves downward. For this reason, a downward force does not act on the rotating portion 71B side of the support rod 71, and no moment force exceeding a certain value acts on the mandrel 7 or the like based on this force. Then, the rotating part 71B of the support rod 71 moved downward is pushed upward,
If the elastic piece 93 is elastically deformed so as to open to both sides by applying an upward force to the elastic piece 93 side by a predetermined value or more, the connecting rod 90 moves into the long hole 70b of the base 71A and rotates. The portion 71B returns to a horizontal state capable of supporting the paper roll R.

In the above description, the case where the paper roll R is mounted on the toilet paper holder H has been described. The same applies to the case where the old paper roll R is replaced with a new paper roll R.

As described above, in the toilet paper holder H, when the mandrel 7 is cantilevered and the paper roll R is attached or detached, the support end (the cylindrical portion 7) of the mandrel 7 is used.
Even if a moment force greater than or equal to a certain value acts on the 0) side, the safety mechanism 9 acts to avoid the action of this moment force on the mandrel 7 or the like. There is no breakage or deformation around it.

In the toilet paper holder H, even if the mandrel 7 is rotated to the paper attaching / detaching position A, the mandrel 7 attempts to return to the paper use position B by the action of the torsion coil spring 8. 7 is not left in a toilet with the support rod 71 side protruding to the user side. Therefore, the arm or the like of the toilet user will not be injured by hitting the support rod 71, and the mandrel 7 will not be damaged by applying unnecessary force to the support rod 71.

Further, the toilet paper holder H
Since the mandrel receiver 5 and the mandrel guide 6 are separate from the holder body 1 and are detachable from the holder body 1, the mandrel 7 may be inconvenient, or the mandrel 7 may be moved by the mandrel guide 6. Even if you ca n’t position enough,
The mandrel guide 6 and the mandrel 7 can be easily replaced. The mandrel receiver 5 and mandrel guide 6 can be attached and detached without removing the holder body 1 from the mounting surface. That is, after the shelf 2 is removed by pushing it upward, the inside of the partition 13 or the side 1 of the holder body 1 is removed.
4, and the tool is pushed downward so that the fixing portion 52 of the mandrel receiver 5 is centered with the tool, thereby releasing the engagement of the projection 52 a with the locking portion 14 f.
Thereafter, the mandrel receiver 5 and the mandrel guide 6 may be pulled down.

Further, since the toilet paper holder H is of a double type in which two paper rolls R can be mounted at the same time, the paper can be used without cutting the paper rolls R. Needless to say, the toilet paper holder H may be a single-type toilet paper holder in which the partition 13 is not provided on the holder main body 1 and the mandrel receiver 5 is attached to one of the side portions 14.

The toilet paper holder H
Is to mount a paper roll R without a core, but by increasing the diameter of the mandrel 7 on the side of the support rod 71,
Even if 1 is used for a paper roll with a core,
Similar effects can be obtained.

Further, in the toilet paper holder H, the torsion coil spring 8 is used as the elastic means for pressing the mandrel 7 toward the paper use position B, but the elastic means may be a leaf spring.

Further, the toilet paper holder H
In the embodiment, the mandrel 7 is held in a horizontal state, but may be held in an oblique state. In addition, mandrel 7
Does not have to rotate the other end side around one end side. For example, the support member of the shaft 7 rotates to
May be positioned at the paper-detach position A and the paper-use position B.

Further, the toilet paper holder H
In the above, the safety mechanism 9 is provided on the mandrel 7 side to prevent breakage of the mandrel 7, but this safety mechanism 9 may be provided on the support member side of the mandrel 7. FIG. 7 shows an example of such a toilet paper holder H1. The support 1 on the holder main body side that supports the mandrel 7 so as to be horizontally rotatable.

The protrusions 52a and the like of the 00 and 110 and the second mandrel 120 engage with the locking portions 13f and the like of the holder main body 1 side, and are attached to the holder main body 1 side.

In this case, as shown in FIG. 10, the left and right pair of second mandrels 120 are arranged so as to face each other, and the first and second mandrel receivers 1 are provided.
Since the protruding portion 122 of the second mandrel 120 is rotatably supported by the pins 00 and 110, the protruding portion 122 of the second mandrel 120 can swing back and forth while resisting the elastic force of the leaf spring 101. Therefore, the paper roll Q having the core tube Q1 is moved from the front to the second mandrel 1.
20, the protrusion 122 pivots rearward and escapes, and the protrusion 122 is returned to its original position by the action of the leaf spring 101 with both ends of the core tube Q <b> 1 at the position of the protrusion 122. The paper roll Q is returned to the position, and the second mandrel 120 supports the paper roll Q in a freely rotatable manner. Also,
To remove the core tube Q1 (or the paper roll Q) from the second mandrel 120, the core tube Q1 (or the paper roll Q) may be pulled forward.

As described above, the toilet paper holder H can be changed to a one-touch toilet paper holder H2 that can use a paper roll Q with a core by simply replacing parts. The use range of H can be expanded.
In this case, since there is no need to replace the main body of the holder 1 or the like, the increase in cost is slight, and the impression of the product after the component replacement is almost the same as the original case.
In addition, parts can be easily replaced by the user without removing the holder main body 1 from the mounting wall.
