Description

The present invention relates to a toilet paper roll holder that holds a roll of toilet paper in a rotatable manner and cuts the toilet paper to the desired length when used.

Figure 6 shows a typical roll holder available on the market. Here, the roll holder 100 comprises a holder body 101 having a pair of left and right side walls 102 and a rear wall 103, and a cover 105 that covers the top of the roll R and is supported by the holder body 101 so as to be freely rotatable in the vertical direction. The roll R of toilet paper is supported so as to be freely rotatable by left and right support members 109 provided on the left and right side walls 102.

When using the toilet paper, the tip portion Ra of the paper is grasped and pulled forward or downward, and then cut to the desired length by the tip of the cover 105a. For toilet paper with perforations at regular intervals, the paper is cut by aligning the perforations with the tip of the cover 105a, or the perforated portion is torn with both hands.

Referring to FIG. 7, the roll holder 200 includes a holder body 201 having a pair of left and right side walls 202 and a rear wall 203, and a cover 205 that covers the top of the roll R and is supported by the holder body 201 so as to be rotatable in the vertical direction. The toilet paper roll R is rotatably supported by left and right support shafts 209 provided on the left and right side walls 202.

Furthermore, the roll holder 200 is provided with cutting teeth 210 on the back surface of the cover 205, which can protrude downward and forward from the cover tip 205a. These cutting teeth 210 are configured to cut the toilet paper at a position that protrudes forward from the cover tip 205a. The cutting teeth 210 are biased rearward by a coil spring 212. When in use, the cutting teeth 210 are caused to protrude a certain amount forward from the cover tip 205a and cut the paper by operating the knob 211. After cutting the paper, the cutting teeth 210 retract, leaving the paper tip Ra protruding a certain amount from the cover tip 205a. As a result, the next time it is used, the paper tip Ra can be grasped and pulled out without having to lift the cover 205.

JP 2005-28163 A

After the toilet paper in FIG. 6 is cut at the cover tip 105a, the vicinity of the paper tip Ra remains in contact with the cover tip 105a, so the paper tip Ra remains in close contact with the outer circumferential surface of the roll R. Moreover, the paper portion behind the paper tip Ra is hidden under the cover 105.

Therefore, when using it again, it is necessary to lift the cover 105 to expose the upper half of the roll R, peel off the paper tip Ra that is in close contact with the outer periphery of the roll R from the outer periphery of the roll R, and pull out the paper tip Ra downward and forward. In particular, when the toilet paper is thin, the paper tip Ra adheres closely to the outer periphery of the roll R, and it is necessary to find and peel off the paper tip Ra while rotating the roll R, which makes the operation of pulling out the paper tip Ra of the toilet paper cumbersome.

In addition, in the roll holder 200 of FIG. 7, compared to FIG. 6, the state of the paper tip portion Ra remaining after cutting protrudes forward by a certain amount from the cover tip 205a, so there is no need to lift the cover 205 for the next pull-out operation. However, when cutting the toilet paper, one hand must keep the cutting teeth 210 in a protruding state against the elastic force of the coil spring 212 while the other hand must cut the toilet paper, so both hands must be used for the cutting operation itself. Also, because the cutting teeth 210, which are wider than the width of the toilet paper, are attached to the cover 205 so that they can slide freely, the structure is complicated and lacks compactness.

The present invention was made in light of the above-mentioned circumstances, and aims to provide a toilet paper roll holder that allows the toilet paper to be pulled out hygienically at the next time of use after the toilet paper has been cut, without touching anything other than the tip of the paper on the roll, and that allows the tip of the paper to protrude from the tip of the cover with a simple operation.

In order to solve the above problems, the toilet paper roll holder of the present invention is a toilet paper roll holder comprising a holder body that rotatably supports a roll of toilet paper, and a cover that covers the top of the roll and is supported by the holder body so that it can rotate up and down, and has a feed pawl that is arranged on the back surface of the cover and has a tip tooth portion that can engage with the outer peripheral surface of the roll and moves back and forth generally along the outer peripheral surface of the roll in the paper-pulling direction and in the opposite direction, a knob that is arranged on the surface of the cover and is connected to the feed pawl so that it can move integrally with the feed pawl, and a spring member that biases the feed pawl in the opposite direction to the paper-pulling direction, and the tip tooth portion is shaped so that when the feed pawl moves in the paper-pulling direction, it engages with the outer peripheral surface of the roll and sends out the paper tip in the paper-pulling direction.

With the above configuration, after cutting the toilet paper, the next time it is used, the tip of the paper can be protruded from the tip of the cover in the paper-pulling direction by the desired amount by simply operating the knob to move the feed claw back and forth several times. This allows the user to effortlessly grasp the tip of the paper and pull it out in the paper-pulling direction while peeling it off from the roll. Moreover, the user does not need to touch the surface of the roll other than the tip of the paper, so the pulling operation can be performed hygienically.

The feed pawl and knob are automatically returned in the opposite direction to the paper-pulling direction by the spring member, so the knob only needs to be operated in the paper-pulling direction, making knob operation easy.

In one aspect of the present invention, the spring member is a spring steel wire formed into a mountain shape. This configuration makes it easy to place the spring member in the narrow space on the back side of the cover.

In one embodiment of the present invention, the tip teeth are formed in a sawtooth shape. With this configuration, when the feed pawl feeds out the outermost layer of the paper on the roll, the sawtooth tip teeth engage and feed out the paper, so the toilet paper is less likely to wrinkle and can be fed out in a taut state.

In one aspect of the present invention, a cover is provided around the spring member. With this configuration, the cover is made of cloth or resin. As a result, when a user replaces or uses the toilet paper, the user's hand touches the cover and does not touch the spring member 24 itself, so the user's hand is not damaged by the spring member 24.

[Embodiment]
A toilet paper roll holder 1 according to an embodiment of the present invention will be described with reference to Figures 1 to 5. For convenience of explanation, as shown by the arrows in Figure 1, the side that is attached to a wall W of a toilet room or the like will be referred to as the "rear" of the roll holder 1, the side from which toilet paper is dispensed will be referred to as the "front", and the left and right directions as viewed from the front will be referred to as the "left and right".

Figure 1 is an overall perspective view of the roll holder 1. The roll holder 1 comprises a holder body 2 that is U-shaped in plan view and has a pair of left and right side walls 3 and a rear wall 4 that are integral with each other, and a cover 5 that is supported on the upper rear ends of the left and right side walls 3 so that it can rotate freely in the vertical direction.

The toilet paper roll R is supported for free rotation by a pair of support members 30 provided on the left and right side walls 3. The cover 5 extends forward from a position close to the rear wall 4 to cover the top of the roll R, and the cover tip 5a is curved or folded forward and downward to abut against the top surface of the roll R near the paper tip Ra at a position forward of the top end of the roll R.

On the back surface (lower surface) of the cover 5, the feed pawl 15, which is a key part of the present invention, is supported so as to be freely movable back and forth in the paper-pulling direction F and the opposite direction, roughly along the outer circumferential surface of the roll R. On the front surface (upper surface) of the cover 5, a slider 11 is disposed, which is connected to the feed pawl 15 through a guide groove 13. The slider 11 is formed in a rectangular shape in a plan view, and a rectangular parallelepiped knob 12 is provided on the upper surface of the slider 11. Therefore, the knob 12, slider 11, and feed pawl 15 can move together along the outer circumferential surface of the roll R in the paper-pulling direction F and the opposite direction.

Figure 2 is a front view of the roll holder 1 with the cover 5 raised, showing the roll R in imaginary lines (two-dot chain lines). In this Figure 2, the cover 5 is rotatably supported on the left and right side walls 3 by support pins 33 provided on both the left and right ends. The support member 30 for supporting the roll supports the core tube Rb portion of the roll R. The left and right support members 30 are rotatably supported on the side walls 3 via the pivot shafts 30a, and as shown in Figure 2, they are rotatable between a use position where they protrude toward each other on almost the same straight line, and a storage position where they rotate upward and are stored in the storage recess 32 of the side walls 3. When supporting a roll R that does not have a core tube Rb, a cylindrical support shaft as an optional member is attached to the roll R and attached to the support member 30.

The guide groove 13 is formed in the center of the left-right width of the cover 5 in an elongated shape extending in the paper-pulling direction F. The feed claw 15 is formed in a rectangular shape that is long in the paper-pulling direction F. The paper claw 15 is biased in the opposite direction to the paper-pulling direction F by a spring member 24 formed from a spring steel wire in a mountain shape, and is locked in a retracted position (position shown in Figure 2) P1. The vicinity of the top of the spring member 24 is connected to a connecting tube 25, which is fixed to the feed claw 15 by a bolt 22 or the like. The vicinity of the left and right ends of the spring member 24 are supported by left and right support tubes 28 fixed to the cover 5 so that they can move in the wire length direction. Furthermore, both ends of the spring member 24 are bent so that they do not come out of the support tubes 28.

The feed claw 15 is located at the center of the left-right width of the back surface of the cover 5, and the tip teeth 15a provided on the paper pull-out direction F side are formed in a sawtooth shape. In this embodiment, as an example of the dimensions of the feed claw 15, the left-right width of the feed claw 15 is approximately 1/4 to 1/3 of the left-right width of the cover 5. In addition, the length of the feed claw 15 in the paper pull-out direction F is approximately 2/3 of the length of the cover 5.

Figure 3 is a cross-sectional view taken along line III-III in Figure 2, and in this Figure 3, the tip teeth 15a of the feed claw 15 are bent or curved so that they face downward and forward. When the feed claw 15 is in the retracted position P1 shown in Figure 3, the tip teeth 15a are located near the top end of the roll R and engage with the outermost paper layer of the roll R. Therefore, when the feed claw 15 moves from the retracted position P1 in Figure 3 in the paper-pulling direction F, the outermost paper layer is also sent in the paper-pulling direction F, and at the same time, the roll R itself rotates a certain amount in the forward rotation direction A.

Figure 4 is an enlarged vertical cross-sectional view of the feed pawl 15, slider 11, knob 12, and the surrounding area. In this figure, the connecting tube 25 connected near the top of the spring member 24 has its extension piece portion 25a sandwiched between two washers 44 and is fixed to the back surface of the feed pawl 15 by the bolt 22 and nut 45. The nut 45 is located in the guide groove 13.

The end of the slider 11 on the paper-pulling direction F side has a nut-engaging recess 11a and faces the upper surface of the feed claw 15 at a distance via a spacer collar 41. The bolt 21 is inserted from below into the feed claw 15 and spacer collar 41, and then protrudes into the nut-engaging recess 11a. The nut 43 in the nut-engaging recess 11a is screwed into the bolt, connecting the end of the slider 11 on the paper-pulling direction F side to the feed claw 15.

The end of the slider 11 opposite the paper pull-out direction F is connected to the feed pawl 15 by the bolt 23, the nut 47 in the nut engagement recess 11b, and the spacer collar 46, just like the end of the slider 11 opposite the paper pull-out direction F. The knob 12 is made of resin and is integral with the slider 11, and is hollow inside.

The front and rear spacer collars 41, 46 slide back and forth in the guide groove 13 in the paper pull-out direction F and the opposite direction. The spacer collars 41, 46 can also be integrally formed with the plastic slider 11.

Figure 5 shows the state in which the feed claw 15 has moved in the paper-pulling direction F to the feed position P2. The tip tooth portion 15a of the feed claw 15 has moved from near the top end of the roll R toward the paper-pulling direction F, and the roll R also rotates in the forward rotation direction A, causing the paper tip portion Ra to protrude a certain amount forward and downward beyond the cover tip 5a. Moreover, the paper tip portion Ra and its surroundings are peeled off from the outer circumferential surface of the roll R.

[Explanation of usage and operation]
After the previous user cuts off the toilet paper, the toilet paper roll is in a state as shown in Fig. 3. That is, the knob 12, slider 11 and feed pawl 15 are retracted to the retracted position P1 due to the elastic action of the spring member 24, and the tip teeth 15a of the feed pawl 15 are engaged with the outer circumferential surface of the roll R near the upper end thereof facing downward and forward.

The next user first moves the knob 12 in the state shown in Figure 3 in the paper-pulling direction F. This operation moves the feed claw 15 in the paper-pulling direction F to the feeding position P2, and the tip teeth 15a feed a fixed amount of the paper portion on the outermost surface of the roll R in the paper-pulling direction F.

Figure 5 shows the state in which the feed pawl 15 has been moved to the delivery position P2. When the knob 12 is released in this state, the elastic force of the spring member 24 causes the knob 12 and feed pawl 15 to retract to the retracted position P1 in Figure 3.

By repeatedly operating the knob 12 as described above to move the feed claw 15 back and forth several times, the user can cause the paper tip portion Ra to protrude downward and forward from the cover tip 5a to the desired length that is easy to pull out.

The user then grasps the paper tip Ra, pulls out the desired amount, and uses the cover tip 5a to cut the toilet paper. During this process, the user does not touch any part of the surface of the roll R other than the paper tip Ra, making it hygienic.

[Effects of the embodiment]
(1) According to this embodiment, by simply operating the knob 12 and reciprocating the feed claw 15, the paper tip portion Ra of the toilet paper can be caused to protrude from the cover tip 5a in the paper-pulling direction F and can be peeled off from the outer peripheral surface of the roll R. This makes it easy to pull out the toilet paper, and the pulling operation can be performed without much touching the roll R itself.

(2) It is hygienic because you can pull out the toilet paper without having to touch the roll R itself.

(3) The feed pawl 15 and knob 12 are automatically returned to the retracted position P1 by the spring member 24, so the knob 12 can be easily operated simply by moving it in the paper-pulling direction F.

[Other embodiments]
(1) The spring member 24 that biases the feed pawl in the opposite direction to the paper-pulling direction is not limited to the spring steel wire formed into a mountain shape as described above, but may also be a coil spring, a leaf spring, a rubber member, or the like.
(2) The present invention may be configured so that a cloth or resin cover is provided around the spring member 24 so that when the user replaces or uses the toilet paper, the user's hands do not touch the spring member 24. With this configuration, when the user replaces or uses the toilet paper, the user's hands will come into contact with the cover and will not touch the spring member 24 itself, so the user's hands will not be damaged by the spring member 24.

Although several embodiments of the present invention have been described, the above-mentioned embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are included in the scope of the invention and its equivalents as set forth in the claims.
