Description

Description Paper holder

[Technical field]

The present invention relates to a paper holder having a mechanism for folding a cut edge of a toilet paper pulled out of a paper roll into a triangular shape.

[Background technology]

Conventionally, in the customer service business such as hotels, as a part of customer service, the cutting edge of the toy paper attached to the toy paper holder is folded into a triangular shape. At present, this is done by employees, but a toilet paper holder with a folding mechanism that mechanically performs this is also proposed.

(See, for example, Patent Documents 1 and 2).

In the paper holder proposed in Patent Document 1, the blade is lowered by operating a cutting operation lever to cut the paper. At this time, the cut edge of the paper is locked to the hook. When the cutting operation lever returns to the original position, pull out the hook while holding the cut end of the paper. At the time of pulling out, the cut edge of the paper is folded back to the right and left sides. The feature is that the cutting of the paper and the folding of the cut edge are continuously performed mechanically.

In the paper holder proposed in Patent Literature 2, the edge of the paper is supported between the upper lid and a plate whose front edge has a triangular shape via a roller. Send the end of the paper to the front side with the transmission belt attached to the plate. At this time, the right and left sides of the edge of the par are slightly bent to the back side by the figure-eight projection fixed to the inner surface of the upper lid and the triangular front edge of the plate. Subsequently, the paper edge passes over a support bar having a blade on the upper surface while making contact therewith. As a result, one edge of the paper is folded in a triangular shape and exposed to the front side of the paper holder. Electric motor-One of the features is to send out the edge of the paper in the evening. In the case of the vapor holder proposed in Patent Document 1, the hook must rotate in conjunction with the operation of the cutting operation lever returning to the original position. The interlocking mechanism required for this operation complicates the structure, and this complicated structure causes a failure and increases the cost. In addition, when the paper is pulled out by the hook, there is a possibility that the paper is not locked to the hook in a state of a single par, so that it lacks certainty.

In the case of the paper holder proposed in Patent Document 2, in order to fold the cut edge of the paper for the next use, the edge of the paper should be located at the inner side of the figure-shaped projection ( It is necessary to perform the operation of returning to the rear side), which complicates the operation, causing a problem of lack of certainty. Also, it is more difficult to mechanically send thin toilet paper than users do, which makes certainty worse.

[Best Mode for Carrying Out the Invention]

As shown in FIGS. 1 to 4, a paper holder 1 according to a first embodiment of the present invention includes a holder body 20 that detachably supports a toilet paper toilet paper 10 and a holder body. An operation lever 30 attached to the holder body 20 to fold the paper 11 at the same time as the paper 11 is sent out from the paper roll 10 attached to the paper roll 20; A paper cutter 40 attached to the holder body 20 for cutting the paper 1 1 and a holder body 20 for folding the paper 11 in cooperation with the operation lever 30. A paper support member 60 for supporting the paper 11 on the upper surface, and a paper pressing member 70 for lightly pressing the paper 11 against the paper support member 60. The holder body 20 includes side plates 21 and 21 on both sides, a connecting member 22 for connecting the side plates 21 and 21 at the rear, and holding members 23 and 2 attached to the side plates 21 and 21. And 3. The connecting member 22 also serves as a base member for attaching the holder body 20 to a wall surface. The holding members 23 and 23 have a movable structure that tilts upward around the base, and rotatably supports the paper port 10 while protruding inward from the inner surfaces of the side plates 21 and 21. I do. By tilting the holding members 23 and 23 upward and fitting them into the recesses 24 and 24 provided on the inner surfaces of the side plates 21 and 21, the new paper rolls 10 can be placed underneath. And the removal of the used paper roll core (not shown). As shown in FIGS. 5 (a) to 5 (d), the operating lever 30 includes a horizontal grip 31 that straddles the holder body 20, and a pair of arms 3 extending downward from both ends of the grip 31.

2, 3 and 2. The arms 3 2 and 3 2 are housed in the side plates 21 and 21 on both sides of the holder body 20 except for the upper end, and the lower end of the arm 3 in the side plates 21 and 21 is the shaft 3.

It is rotatably supported by 3, 33. Then, the operating lever 30 is elastically held at a substantially vertical original position in a state where the operating lever 30 can be tilted to the front side, that is, the front side by the springs 34, 34 for elastically pulling the arms 32, 32 backward. Is done.

The operation lever 30 is connected to a paper support member 60 erected between the arms 32 and 32 on both sides, and the paper support member 60 is placed in front of the operation lever 30, that is, in front of the operation lever 30. Reciprocates as the robot moves forward and backwards. The paper support member 60 is a horizontal thin plate that supports the paper 11 pulled out from the upper side of the paper roll 10 to the near side almost downward from below, and the front end 61 of the paper support member 60 is formed of the paper 11. The cut edge protrudes in a triangular shape to the front side in order to fold the cut edge in a triangular shape. The vertex angle of the front end 61 corresponds to the folding angle of the cut edge of the paper 11, and is set to about 120 degrees here.

The vapor pressure member 70 mounted on the operation lever 30 is provided with rollers 72, 72 mounted in the longitudinal direction of a support shaft 71 rotatably mounted between the arms 32, 32. Have. The rollers 72, 72 are in contact with the upper surface of the paper support member 60, and can move up and down so as to be able to retreat upward from this state. For this elevating operation, the support shaft 71 is fitted into elongated holes 73, 73 provided on the inner surfaces of the arms 32, 32.

The rollers 72, 72 are configured to be pressed downward by the hand when the grip 31 of the operation lever 30 is gripped by the hand. 11 is pressed against the paper support member 60 to prevent the paper 11 from slipping against the paper support member 60. When the hand releases the operation lever 30, the operation lever 30 returns to the original position, and at this time, the support shaft 71 of the rollers 72, 72 retracts the long holes 73, 73. Therefore, when the paper support member 60 returns to the original position, only the paper support member 60 returns, and the paper 11 is not pulled.

ぺ If you want to cut the edge of the holder 40 with the blade facing down, It is erected between the upper ends. The paper cutter 40 is disposed with a predetermined gap further in front of the paper support member 60 attached to the operation lever 30. When the operation lever 30 is tilted forward, the paper support member 60 and the paper 11 thereon pass below the paper cutter 40. When the paper pad 40 is cut with a paper cutter 40 by arranging the paper pad 40 with a predetermined gap in front of the paper support member 60, as shown in Fig. 8 (a). As described above, the cut edge portion 12 surely hangs downward from the front edge portion 61 (more strictly, the center front end portion) of the vapor support member 60. The friction member 50 is a substantially horizontal resin rod provided between the side plates 21 and 21 of the holder main body 20 along the paper force 40, and the operation lever 30 is tilted forward. The paper support member 60 is displaced to the front side, that is, the front side of the paper cutout 40, that is, to the lower side so that the paper support member 60 passes over the friction member 50 when it is made. I have.

The friction member 50 is composed of a first bar member 50A located on the left side as viewed from the front and a second bar member 50B located on the right side. The first bar member 5OA, which is supported on the inner surface of the left side plate 21 in a substantially horizontal cantilever manner, has a mounting portion 51A as shown in FIGS. 6 (a) to 6 (e). The distal end portion is a working portion 52 A having a flat portion. As shown in FIGS. 7 (a) to 7 (e), the second bar member 50B supported by the inner surface of the right side plate 21 in a substantially horizontal cantilever manner has a mounting portion 51 B, the tip is an action part 52 B having a flat part.

The two bar members 5OA and 50B are combined so that the working portions 52A and 52B at the tip end at the center between the side plates 21 and 21 with a gap 50C therebetween. More specifically, the inclination of the acting portion 52A of the butted portion (FIG. 6 (b)) and the inclination of the acting portion 52B (FIG. 7 (b)) correspond to the V-shaped recess 53 (FIG. 2). ), And the butted portion of both bar members 50 A and 50 B forms a gap 50 C following the V-shaped recess 53, and the planes of the working portions 52 A and 52 B. The part is configured to face diagonally upward.

Thus, when the operation lever 30 is tilted to the front side, the triangular front end 61 of the paper support member 60 is inserted into the V-shaped recess 53 with its advance. At the same time, it moves forward while abutting on the flat portions of the action portions 52A and 52B. However, the two bar members 5OA and 50B constituting the friction member 50 are arranged such that the mounting portions 51A and 51B at their base end portions are located on the front side against the urging force of the spring. It is naturally mounted so that it can rotate slightly.

Next, the function of the paper holder 1 according to the first embodiment will be described with reference to FIGS. 8 (a) to 8 (c).

When setting the paper roll 10 in the holder body 20, pull out the paper roll 11 from the top of the paper roll 10 along the upper surface of the paper support member 60 toward you. More specifically, the paper 11 passes between the paper support member 60 and the paper pressing member 70, passes over the paper support member 60, and finally passes through the paper force The holder body 20 is pulled out from the space between 40 and the friction member 50 toward the front side, that is, toward the front side. FIG. 8A shows a state in which the paper 11 pulled out to the front side of the holder body 20 is cut with a paper holder 40. The cut edge 12 of the paper 11 hangs downward from the central tip of the triangular front end 61 of the paper support member 60.

When the triangular front end 61 of the paper support member 60 advances on the friction member 50, the front end 61 comes into sliding contact with the friction member 50. Specifically, the triangular front end 61 of the paper support member 60 enters the νΊ dog recess 53 from the back side (opposite side of the front side), and the action parts of the bar members 5OA and 50B. Slide in contact with each of the 52A and 52B planes. Here, in the V-shaped concave portion 53, the inclination of the acting portion 52B of the bar member 50B is gentler and taller than the inclination of the acting portion 52A of the bar member 50OA. In other words, since the action portion 52B protrudes in the traveling direction of the paper support 11, the front end 61 of the paper support member 60 is located at one end of the V-shaped recess 53. And then hit the other side.

As a result, the cut end 12 of the paper 11 hanging downward from the central front end of the triangular front end 61 of the paper support member 60 is supported by the friction member 50 to support the paper. The members 60 are sequentially folded back along the front end 61. More specifically, as the paper support member 60 advances, the cutting edge 12 of the paper 11 hanging from the triangular front end 61 of the friction member 50 While being pulled up along the side forming the V-shaped recess 53, it moves to the front side of the V-shaped recess 53, and a part thereof moves to the gap 50 C. As a result, the cut end 12 of the paper 11 is narrowed, so that the paper 11 folded at the front end 61 of the paper support member 60 becomes the triangular front end of the paper support member 60. It is folded into the same triangle shape as the shape of part 61. In the folding process, there is friction between the paper 11 and the paper support member 60, and furthermore, friction between the paper 11 and the friction member 50. 1 1 is also derived from 10 per roll 10. Therefore, the tip portion of the paper 11 that is folded in a triangular shape can be projected forward of the holder body 20.

At this time, as described above, the V-shaped concave portion 53 has a functioning portion 52B of the bar member 50B acting in the traveling direction of the paper 11 as compared with a functioning portion 52A of the par member 50A. Since the part 52B protrudes, the cut end part 12 of the paper 11 is folded at a short timing from the working part 52B side first, and then the working part 52A side immediately after. Can be This slight difference in timing causes the cut edge 12 of the paper 11 to be folded into a well-shaped triangle. Thus .. The cut edge 12 of the paper 11 is folded in a triangular shape and protrudes in front of the holder body 20 (Fig. 2).

At this time, the bar members 50A and 50B constituting the friction member 50 are supported by the side plates 21 and 21 of the holder body 20 in a cantilever manner, and are easily bent. In addition, it rotates slightly to the front side against the spring force. As a result, the friction member 50 is pressed naturally to the front end 61 of the paper support member 60, and the cutting edge 12 of the paper 11 is smoothly folded.

After tilting the operating lever 30 to the limit, release the hand and remove the external force applied to the operating lever 30 and the top-par pressing member # 0. The operation lever 30 automatically returns to the original position together with the vapor support member 60 and the vapor press member 70 by the elastic force of the spring 34.

At this time, since the paper pressing member 70 is a roller that is easily rotated, the cut end portion 12 of the paper 11 remains at the cut position without being pulled back. This state is shown in Fig. 8 (c).

Cut paper 1 1 that is folded into a triangular shape and protrudes toward the front of holder body 20 The studs 1 and 2 are easy to pull out and look good. After pulling the cut edge 12 and pulling out the paper 11 to the required length, the paper 11 is cut with a paper cutter 40. As a result, the state returns to the state shown in FIG. 8 (a), and the cut edge 12 of the paper 11 is again moved from the central front end of the triangular front edge 61 of the vapor support member 60. It hangs down.

Whenever the operating lever 30 is tilted to the near side each time the paper 1 1 is used, the cutting edge 12 of the paper 1 1 is folded in a triangular shape and protrudes toward the front of the holder body 20. . Not only does the motor not be used, but also the operation of pulling the control lever 30 forward (one reciprocating operation), and both the feeding and folding of the cut end 12 of the paper 11 1 are performed. Easy.

When a new paper roll 10 is set in the paper holder 20, pass the paper end between the paper support member 60 and the paper pressing member 70, and pass over the paper support member 60. Then, it is necessary to pull out from between the paper cutter 40 and the friction member 50 to the front side of the holder body 20, but the paper pressing member 70 retreats upward, and the paper supporting member 60 and This operation is simple because the space between the paper pressing member 70 and the paper pressing member 70 is greatly widened. To eject the used paper roll 10 upward, tilt the operation lever 30 forward (see Fig. 8 (b)). As a result, the upper part opens greatly, and the discharging operation is simplified.

[Example 2]

Next, a paper holder 100 according to a second embodiment of the present invention will be described. FIG. 9 is a perspective view of the paper holder 100, FIGS. 10 (a) to (c) are diagrams for explaining the folding operation of the paper of the paper holder 100, and FIGS. 11 (a) to (c). c) is a diagram showing the timing of the operation, and FIGS. 12 and 13 are diagrams showing a state in which the side plate on the operation lever side is removed and the operation lever is at the original position, that is, the most front position. 14 (a) to (c) are diagrams for explaining the operation of a cam, an arm member, and a paper hanging member related to the operation of the operation lever, and FIG. 15 is used for a paper holder 100. FIG. 5 is a three-sided view of the friction member.

The main difference between the paper holder 100 according to the second embodiment and the paper holder 100 according to the first embodiment is that the operation of the operation lever 130 is interlocked. By lowering the one-part hanging member 180, the one-part part 111 is surely hung from the triangular front end of the paper supporting member 160, and the paper hanging member 180 is immediately returned to its original position. , And then the paper support member 160 is moved forward, that is, toward the front (see FIG. 10).

Another difference is that the frictional resistance with the vapor on the upper surface of the friction member 150 is increased in order to ensure the folding of the paper. In order to increase the size of the friction member, it is preferable that elastic members 155 and 157 are provided on the upper surface of the friction member 150 (see FIG. 15). As the elastic bodies 155 and 157, use springs, dishpanes, rubber, or the like, or use special paint that gives elasticity to the application surface to increase friction resistance. Apply on top of

Further, the friction member 150 has a single structure, and includes a paper narrowing recess 154 following the V-shaped recess 153 provided at the center. This paper narrowing concave portion 15 4 corresponds to the gap 50 C of the paper holder 1, extends from the bottom (front side) of the V-shaped concave portion 15 3, and has a cutting edge of the paper. By moving the cut end portion of the paper to the paper narrowing concave portion 154 so that the portion is stably folded into a triangular shape, the area is narrowed down.

Further, the rod-shaped paper angle equalizing member 190 is set so that the angle between the paper par supplied from the paper roll 110 and the paper par support member 160 does not change depending on the amount of toilet paper reduction. It is provided between the paper roll 110 and the paper support member 160, and the paper is supplied from the paper roll 110 to the paper support member 160 through the paper angle equalization member 190. (See Figure 9).

Further, the paper pressing member 170 is provided on the back side of the cover member 210, and when the force bar member is normally closed, the paper pressing member 170 presses the paper supporting member 160 lightly. I'm going to do it. In this structure, the paper pressing member 170 presses the paper 111 securely against the paper support plate 160 with a predetermined small pressing force (see FIGS. 9 and 10). And different. Other different parts will be clarified in the description of the paper holder 100.

First, the main difference, the paper hanging member 180, will be described. As shown in FIG. 9, the paper hanging member 180 is provided across the inner wall side of the side plates 121, 121. As described below, it is supported by a cantilever. First, the relationship between the movement of the paper hanging member 180 and the movement of the paper supporting member 160 will be described with reference to FIGS. 10 and 11, and then the mechanisms will be described.

Fig. 10 (a) shows the operation lever 13 (Fig. 9) having a single arm 13 2 in the original position before operation, and the paper 1 11 shows the cover member 2 10 The paper is cut by a paper cutter 140 attached to a lower portion of the tip portion, and the cut edge is on the friction member 150. In this position, the rod-shaped paper hanging member 180 is always located above the paper 111.

At time tl in Fig. 11, when the operating lever 130 is tilted forward, that is, toward the front (to the left in the figure), at time t2 immediately after the start of the tilting operation, the paper hanging material 1 80 Moves downward, and the cut end of the paper 1 1 1 1 hangs down from the front end of the paper support member 160 having the same shape as that of the first embodiment, as shown in FIG. 10 (b). . Due to the continuous tilting operation of the operation lever 130, the paper hanging member 180 rises and immediately returns to the original position (time t3). The operation of the paper hanging member 180 constitutes one operation as a pair of lowering and raising. At a subsequent time t4, the パー one-par support member 160 starts to move forward, that is, forward. Since the triangular front end of the paper support member 160 engages with the cutting edge portion of the paper 1 1 1 hanging down in front of the paper support member 160, the advance of the paper support member 160 is determined as follows. The paper is pulled out from the parlor, and the front end of the paper 111 is sandwiched between the back surface of the paper support member 160 and the friction member 150 to move forward, and the cover 210 is moved forward. Stops at a position protruding by a predetermined length from the tip of the (time t5).

Next, when the operation lever 130 moves in the reverse direction, that is, retreats, only the paper support member 160 retreats (to the right in the drawing), and as described later, the leading end of the paper 111 Remains folded as shown in Fig. 10 (c). The front end of the paper supporting member 160 has a triangular structure as in the first embodiment, and as described later, the friction member 150 has a triangular structure of the paper supporting member 160. In cooperation with the front end, the front end of the paper 11 is folded in a triangular shape, and the triangular paper protrudes from the tip of the cover member 210. At this time, the operation timing of the operation lever 130, the paper hanging member 180, and the paper supporting member 160 is as follows. As is clear from the above, the results are as shown in FIGS. This operation timing is important.

Next, a mechanism for performing the above-described operation will be described. FIGS. 12 and 13 show the respective members attached to the inner wall 122 by removing the side plate 121 on the operation lever 130 side. FIG. 12 shows a state in which the operating lever 130 is released, and FIG. 13 shows a state in which the operating lever 130 is tilted to the front, that is, to the front (left side in the drawing). The main members shown in Fig. 12 and Fig. 13 move the paper support plate 160 in the horizontal direction of the drawing by moving by engaging the operation lever 130 and the operation lever 130. Auxiliary lever 220 to be moved, cam 230 that rotates by engaging with operation lever 130, arm member 240 that moves by engaging with cam 230, and a tip portion thereof One end is fixed to the paper hanging member 180 supported.

That is, the paper hanging member 180 is cantilevered and supported by the arm member 240. The control lever 1 30 is on the front side of the paper, and the cam 2 30 is the innermost wall 1

The auxiliary lever 220 is located at the intermediate level between the operating lever 130 and the cam 230.

The inner wall 122 has a horizontal elongated hole 123 and a vertical elongated hole 124. As will be clarified later, the horizontal slot 1 23 is necessary for the auxiliary lever 220 to move the paper support plate 160 left and right in the drawing. 4 is necessary to move the paper hanging member 180 up and down.

The operation lever 130 and the auxiliary lever 220 are attached to the inner wall 122 so that they can rotate at a certain angle by the same rotary shaft 133. Rotating shaft 1

A spring 1 3 4 is interposed between the operation lever 1 3 0 and the auxiliary lever 2 2 0 in 3 3, one end of the spring 1 3 4 is locked by a locking member 1 3 5, and the other end Is locked to the operation lever 130 (not shown).

The operating lever 130 is bent in the shape of a letter in the middle of the arm 132, and has a protruding portion 136 protruding in the direction opposite to the paper surface (in the direction of the inner wall 122) at that portion. The projecting portion 1336 engages with the engaging portion A of the auxiliary lever 220 during the tilting operation of the operating lever 130 to move the auxiliary lever 220 together. is there. Also, the operation lever 130 is a force that projects in the reverse direction of the paper It has a memory engagement portion 13 7. The cam engaging portion 1337 engages with the first engaging portion 2332 of the cam 230 through the window portion 221 of the auxiliary lever 220, so that the fulcrum 231 is centered. To rotate the cam 230. Here, the operation lever 130 is composed of a single arm 13 2, and the grip 130 is different from the operation lever 30 of the vapor holder 1 in that the grip 131 is spherical.

The auxiliary lever 220 is bent in the shape of a letter in the middle, and has a window portion 222 of a predetermined size. The locking portion 222 of the auxiliary lever 222 is coupled to the fixed portion 125 of the inner wall 122 by a spring 222. In addition, the auxiliary lever 220 supports the paper support plate 160 in a cantilever manner at its upper part 244. When the operation lever 13 is tilted, the cam engagement part 13 7 is simultaneously opened when the projection 13 of the operation lever 13 engages with the engagement point A during the operation. It is configured to engage with the engagement portion B on one side of 222. This is to prevent the load from being applied to one location and to increase reliability by distributing the force to two locations.

The reason why the auxiliary lever 220 is used in the second embodiment is to provide the above-described operation timing between the operation of the paper hanging member 180 and the operation of the paper support member 160. In other words, the auxiliary lever 220 has a time lag, so that the paper dropping member 180 performs the lowering operation and the raising operation first, and after that, the paper support member 160 is moved. To provide a time difference moving mechanism for

As shown in FIG. 14, the cam 230 has a fulcrum 2 31, a first engaging portion 2 32 engaging with the cam engaging portion 1 36 of the operating lever 130, and an arm member. A second engaging portion 2 33 engaging with 240 and a locking portion 2 34 are provided. One end of a spring 235 is connected to the locking portion 234, and the other end of the spring 235 is connected to a fixed portion 125 of the inner wall 122. The cam 230 receives the force from the cam engaging portion 1336 of the operating lever 130, and rotates clockwise about the fulcrum 231.

The arm member 240 includes a first arm portion 241 having a U shape, a second arm portion 242 formed integrally with the first arm portion 241, and a fulcrum 2. 4 consists of 3. One end of a paper hanging member 180 is fixed to a tip portion of the first arm portion 241. The paper hanging member 180 is supported by the arm member 240 in a cantilever manner, and extends in the direction of the other side plate (back side of the paper). And the tip of the arm member 240 The portion is connected to one end of the spring member 245, and the other end of the spring member 245 is fixed to the fixed portion 126 of the inner wall 122 (FIG. 12).

As shown in FIG. 15, the friction member 150 is a single member having a V-shaped concave portion 153 and a paper narrowing concave portion 154 substantially at the center of the side where the paper 11 is received. And is fixed to the inner side wall 1 2 2 of the side plates 1 2 1 and 1 2 1 so as to be inclined obliquely downward. The V-shaped recessed part 15 3 is basically the same as the V-shaped recessed part 53 of the paper holder 1 of the first embodiment, and has a triangular shape that fits the triangular front end of the paper support member 160. It has sides 15 A and 15 B forming sides. In order to explain the function of the one-part narrowed concave part 15 4, the V-shaped concave part 15 3 and the one-part narrowed concave part 15 5 4 are separated. It can be considered a part of 15 3.

A paper narrowing recess 154 corresponding to the gap 50 C of the paper holder 1 extends from the bottom (front side) of the V-shaped recess 153. The paper narrowing recesses 1 5 4 are formed so that the cutting edge of the paper 1 1 1 is narrowed so that the cutting edge of the paper 1 1 1 does not spread when the paper is folded. It works to narrow down the area. As will be described later, paper 1

11 is stably folded into the same triangular shape as the triangular shape at the front end of the paper support member 160.

In addition, the friction members 150 are elastic members 1 protruding from the upper surfaces on both sides of the V-shaped concave portion 1503.

5 5 and 1 5 7 are provided. These elastic members 155 and 157 are made of a combination of a plurality of thin springs, a plate spring and a disc spring, rubber, or a synthetic resin material having high elasticity. Furthermore, a special paint may be applied to the upper surface of the friction member 150 to impart elasticity, or a tape having a rough surface may be adhered to the upper surface of the friction member 150.

It is preferable that the elastic members 155 and 157 have such an inclination that the height increases from the side where the paper 111 is received to the side where the paper is sent out. Since the elastic members 155 and 157 have such an inclination, as shown in FIG. 10 (c), the paper supporting member 160 becomes the friction member 150 via the paper 111. When contacting the paper support member 1

The lower surface of 60 covers the entire upper surface of the elastic members 15 5 and 15 7 via paper 11 1. The paper is pressed between the lower surface of the paper support member 160 and the upper surfaces of the elastic members 1 5 5 and 1 5 7. At the same time that the paper roll 110 is pulled out from the paper roll 110 at the same time. The friction member 50 may also be provided with the above-described elastic body or may be coated with a special paint.

As shown in FIG. 9, a single bar-shaped paper angle equalizing member 190 is provided over the inner side walls 122 of both side plates 121, 121. The paper 111 from the paper roll 110 is drawn out from between the back surface of the cover member 210 and the paper angle equalizing member 190, and the paper support from above the paper angle equalizing member 190. The angle at which the paper is fed onto the paper support member 160 regardless of the diameter of the paper roll 110 depending on the degree of paper used because the paper is pulled out on the support member 160 Becomes uniform.

This is especially true when the paper is near the end and the diameter of the paper roll 110 is small, because the paper is curled, so that the paper pressing member 170 can be used as a paper. This is effective when the support member 160 is pressed onto the surface.

Next, with reference to these drawings, the operation of each related part associated with the tilting operation of the operation lever 130 will be described.

As shown in FIG. 11, at time t1, when the operating lever 130 starts to tilt forward, that is, toward the front (toward the left side of the drawing), immediately at time t2, the cam engaging portion 1 of the operating lever 130 is turned on. 36 engages with the first engaging portion 2 32 of the cam 230 to rotate the cam 230 clockwise about the fulcrum 2 31. This is illustrated in Figure 14.

As the operating lever 130 advances, the second engaging portion 233 of the force member 230 receives the force from the cam engaging portion 137 of the arm member 240 and the second engaging portion 233 of the arm member 240. The arm 2 4 2 is rotated counterclockwise about the fulcrum 2 4 3, and the tip of the arm-shaped arm 2 4 1 supporting the paper hanging member 180 is attached to the spring member 2. While extending 45, it is lowered through the longitudinal slot 124 (FIG. 14 (b), (c);). By this operation, the paper hanging member 180 descends, and the cut edge of the paper 111 is hung from the tip of the paper supporting member 160. Then, when the cam engaging portion 1336 of the operation lever 130 moves further forward and disengages from the first engaging portion 232 of the cam 230, the tension force of the spring 235 in the extended state is applied. Therefore, at time t3, the cam 230 returns to the original state shown in FIG. 14 (a), and the tip of the arm-shaped arm portion 241 is drawn by the pulling force of the spring member 245. The paper hanging member 180 also rises and returns to its original upper position. Here, just before the cam engaging portion 1 37 of the operating lever 130 is disengaged from the first engaging portion 2 32 of the cam 230, the paper hanging member 180 is at the lowest position. .

When the operating lever 130 is further tilted forward, at time t4, the projections 1 36 and the cam engaging portions 1 3 7 of the operating lever 1 3 Engage with B. By this engagement, the auxiliary arm 220 performs a tilting operation together with the tilting operation of the operating lever 130. Along with this, the vapor support member 160 supported by the cantilever on the upper part of the auxiliary arm 220 moves forward (to the left in the drawing).

As the triangular front end of the paper support member 160 advances between the elastic members 150 and 157 of the friction member 150, the triangular front end of the paper support member 160 is moved forward. The cut end of the paper 1 1 1 hanging from the end is pulled up along the sides 15 3 A and 15 3 B forming the V-shaped recess 15 3 of the friction member 150. Move to the front side (bottom side) of the V-shaped recessed part 15 3, and further move to the paper narrowing recessed part 15 4. As a result, the cut edges of the paper 1 1 1 1 are gathered and narrowed in the paper narrowing recesses 1 5 4, so that the paper 1 1 1 folded back at the front end of the paper support member 1 6 The support member 160 is folded into the same triangular shape as the front end of the triangle.

Then, the paper support member 160 advances further, and the lower surface of the paper support member 160 is brought into contact with the elastic members 150 and 157 of the friction member 150 via the folded paper 111. When they come into contact, the paper 111 folded on the lower surface of the paper support member 160 is hardly moved because it is sandwiched between the paper support member 160 and the elastic members 150 and 157. Thereafter, as the paper support member 160 advances, the paper 111 is pulled out from the paper roll 110. Therefore, the front end portion of the paper 111 folded in a triangular shape can be projected toward the near side of the cover member 210. At time t5, the operation lever 13 0 and the paper support member 16 0 0 are in the foremost position, and the paper support member 16 0 is folded in a triangular shape that is almost the same as the shape of the triangular front end thereof. The part is projected from the cover member 210.

Next, when the operating lever 130 is released by releasing the hand from the grip 131, the operating lever 130 returns to the original position by the action of the spring 13 (time t7). Similarly, the auxiliary lever 220 returns to its original position by the action of the spring 222. Along with this, the paper support member 160 also retracts (to the right in the drawing) and returns to its original position (t6) _0, that is, at time t7, all members return to their original positions.

Here, the paper support member 160 is made of a slippery material and structure so as to reduce the frictional resistance with the paper 111, so that when the paper support member 160 is retracted, it is folded. The paper 11 does not recede together with the paper support member 160. In this way, a paper par with the cut edge folded in a triangular shape can be obtained stably and reliably.

The cover member 210 of this embodiment has spring portions 211 (FIG. 9) protruding rearward on both side surfaces. When the cover member 210 is closed, the panel part 211 has a spring structure that projects somewhat in the side direction so as to press the inner side walls 122 of both side plates 121 with a predetermined force. It has become. As a result, the paper pressing member 170 presses the paper 111 against the paper supporting member 160 with a stable predetermined force. More preferably, when the toilet paper is cut with a paper cutter 140 provided at the end of the cover member 210, the cover member 210 can be used without pressing the cover member 210 with the other hand. When the pressing force is such that the paper cannot be opened, it can be operated with one hand. Can be obtained. The cover member 210 is opened and closed by a bearing in the same manner as a general paper holder, and is provided with a convex portion or a concave portion (not shown) at the bearing portion. May be engaged with a side wall or an engaging portion (not shown) extending from below. By doing so, the cover member 210 can be stably closed at a fixed position. In the second embodiment, the paper angle equalizing member 190 is formed as a single rod. However, a pair of the side plates 1 2 1 and 1 2 1 extending from the inner side wall 1 2 The toilet paper roll may be set in the paper holder, or the toilet paper may be easily pulled out when the toilet paper is pulled out from between the cover 210 and the paper angle equalizing member 190. The angle equalizing member 190 may be configured to be tilted upward or forward. In addition, both ends of the vaporizer angle equalizing member 190 are supported by elongated holes (not shown) formed on the inner side wall 122 of the side plates 122 and 121 and extending toward the front side. In this way, the paper angle equalizing member 190 can be moved to the front by the slot when the toy pellet per roll is replaced, and the cover member 210 and the paper angle equalizing member 1 can be moved forward. Since it is separated from the paper 90, the paper can be easily pulled out between the back surface of the cover member 210 and the paper angle equalizing member 190.

Further, it is preferable that the paper support member 160 is curved with a gentle curve, and with the tilting operation of the operation lever 130, the paper support member 160 moves forward with a gentle curve, A reversing operation is performed, and this helps the paper holder 100 to operate stably. The paper support member 60 in the first embodiment may of course be curved by a gentle curve.

In the above embodiment, the tip of the toilet paper is folded in a triangular shape by inclining the operation lever by hand, but since a toilet power outlet is generally provided with a commercial power outlet. An electric motor such as a stepping motor may be used to rotate a lever (not shown) corresponding to the operation lever 130 at a certain angle. At this time, a push button (not shown) is provided on the side plate 122 in place of the grip of the operation lever, and when the push button is pressed, the electric motor operates, and the operation lever operated by the electric motor is operated. (Not shown) and the auxiliary lever 220 are operated as described above to lower and raise the paper hanging member 180. In this case, although not shown, a double cam mechanism is directly connected to a rotating shaft of an electric motor (not shown), and the arm member 240 is firstly driven by a first cam (not shown) each time the motor rotates once. A structure in which the paper hanging member 180 performs a lowering motion and a rising motion by operating, and then the auxiliary lever of the paper support member 160 is directly tilted by a second cam (not shown). You can also

In addition, the downward movement and the upward movement of the paper hanging member 180 are performed by a paper support member 1 Since 60 must be completed in a short time until the forward movement is performed, the spring member 2 45 of the arm member 240 and the spring 2 35 pulling the cam 230 have relatively large pulling force. . For this reason, when the cam engaging portion 1 37 of the operating lever 130 is disengaged from the first engaging portion 2 32 of the cam 230, the cam 2 30 and the arm member 2 4 Since 0 returns to the original position at high speed, noise may be generated and the life may be shortened. To prevent this, the portion where the cam 230 comes into contact with the arm member 240 or not shown, but protrudes from the inner wall 122 to restrict the operation of the arm member 240 if necessary. It is preferable to provide a cushioning member (not shown) made of rubber or a flexible synthetic resin in a stopper portion or the like.

Furthermore, the V-shaped concave portion in the present invention may have a wider width at the entrance side (back side) where paper is received than at the bottom side (front side), and the sides forming the V shape may be arc-shaped. Then, if the gap 50 C or the paper restraint recess 154 following the bottom side (front side) of the V-shaped recess narrows and restrains the cut edge portion of the paper to such an extent that operation is not hindered, the paper support member It can be folded into almost the same shape as the triangular front end of 160. The gap 50 C or the vapor-constrained concave portion 154 may of course be a part of the V-shaped concave portion.

Further, in the above embodiment, various shapes of the operation levers 30 and 130 and the auxiliary lever 220 can be considered, and the shapes and structures are not limited to those in the embodiment. For example, the operation lever may be of a dial type. By rotating a disk serving as the dial, the paper support member 160 moves forward and backward, and the time difference moving mechanism including an auxiliary lever is used. Of course, a structure for operating the. Further, the grip 13 1 may protrude in the lateral direction of the side plate. Further, the auxiliary lever 122 may be S-shaped. Further, the operation lever 130 and the auxiliary lever 220 are engaged at two places, but may be at one place or three or more places.

Furthermore, in the above embodiment, the paper was supported on the paper supporting member, but two sheets of the above-mentioned shape facing each other at an interval at which the paper can freely pass, for example, at an interval of several mm, were combined. Alternatively, a structure in which the paper is supported from both sides perpendicular to the paper traveling direction so as to be supported below the paper support member may be used. In this case, the paper support member itself guides the paper, Since the function of the pressing member is also performed, the paper pressing member can be omitted. In this case, if the two plate-like members are opened, it is convenient to pass the paper through the paper supporting member when replacing the paper roll.

In the above embodiment, the entire front end of the paper supporting members 60 and 160 is formed in a triangular shape, so that the front end is inclined all the way. However, both sides of the front end are not triangular. May be. The reason for this is that the exposed end of the cut edge of the triangular folded paper is at most about 2 cm, so the central part of the front end of the paper support members 60 and 160 has a triangular shape. If so, the paper exposed from the paper holder can be triangular.

In the above embodiment, the toilet paper is described. However, the present invention can be similarly applied to a paper roll of paper dinner and a paper roll of cooking paper.

According to the present invention, it is possible to provide a paper holder capable of reliably folding a cut edge portion of a paper into a triangular shape with a simple structure.
