Description

[Technical Field]

[0001] The present invention relates to a toilet paper holder, and more particularly to a toilet paper holder that is characterized by making it easier to grip the toilet paper. [Background technology]

[0002] When you go to the bathroom, you often see torn pieces of toilet paper lying on the floor as litter. One of the reasons for this is that the tip of the toilet paper in the toilet paper holder is difficult to grip.

[0003] Furthermore, when trying to remove toilet paper from the toilet paper holder, if the tip of the toilet paper is still attached to the body of the toilet paper, it is difficult to grab it quickly. In particular, if a user removes toilet paper from the toilet paper holder and then tries to remove it again, they may feel flustered and frustrated if they are unable to grab the toilet paper quickly.

[0004] Therefore, a toilet paper holder that makes it easier to remove toilet paper has been proposed (see Patent Document 1). The toilet paper holder disclosed in Patent Document 1 has a receiving stand equipped with a wire and a stand placed under the lid of the toilet paper holder. The toilet paper is passed between the lid and the receiving stand, and the leading end of the toilet paper is lifted by the receiving stand from the main body of the toilet paper, making it easier to grasp.

[0005] The toilet paper holder disclosed in Patent Document 1 has the problem that when trying to lift the tip of the toilet paper sufficiently, the lid may also lift up along with the holder, causing the lid to lose its original function. For this reason, the toilet paper holder disclosed in Patent Document 1 is unable to lift the tip of the toilet paper sufficiently, and the toilet paper may still be difficult to grasp.

[0020] (Overview of Toilet Paper Holder 10) 1 to 9, a toilet paper holder 10 according to one embodiment of the present disclosure will be described. The toilet paper holder 10 of this embodiment is used as a toilet fixture and stores and holds a roll of toilet paper 1. The toilet paper holder 10 is placed on the floor of the toilet or attached to the wall of the toilet. The toilet may be a Japanese-style toilet or a Western-style toilet. The location where the toilet is installed is not particularly limited, and may include a home, a facility, a vehicle, or outdoors. The toilet paper holder 10 has a base plate 16, and the base plate 16 is placed on the upper surface of the toilet floor. Alternatively, the toilet paper holder 10 does not have a base plate 16, and may be placed on a part of the toilet floor as the base plate 16. The toilet paper holder 10 has a back plate 17 that is perpendicular to the bottom plate 16. The angle between the bottom plate 16 and the back plate 17 is 90 degrees. To maintain the 90-degree angle between the bottom plate 16 and the back plate 17, a square piece of timber 19 is placed against the angle between the bottom plate 16 and the back plate 17, and the bottom plate 16 and the square piece 19 are fixed together with adhesive or nails, and the back plate 17 and the square piece 19 are fixed together with adhesive or nails. It should be noted that toilet paper holder 10 does not necessarily have back panel 17, and part of the toilet wall may serve as back panel 17.

[0021] The toilet paper holder 10 includes a core rod 2, a core rod support portion 4, a pressure plate 12, an air discharge portion 13, an air pump portion 14, an external force receiving portion 15, and a transmission portion 22. The core rod 2 is inserted into the hole 1a of the toilet paper 1 to hold the toilet paper 1.

[0022] (About core rod 2) The core rod 2 is a rod-shaped body and has metal portions (a right-side metal portion 30 and a left-side metal portion 31) on both ends. The right-side metal portion 30 and the left-side metal portion 31 are made of magnetic metal and have a thin, disk-like shape. The magnetic force of a permanent magnet 21 (described later) attached to the core rod support portion 4 acts on the right-side metal portion 30 and the left-side metal portion 31, attracting them, and the core rod 2 is supported by the core rod support portion 4. The permanent magnet 21 may be, for example, a neodymium magnet, and is not limited to a particular type.

[0023] (Regarding the core rod support part 4) The core rod support portion 4 supports the core rod 2 by magnetic force. The core rod support part 4 includes a rear reinforcing plate 23, a right side plate member 5, and a left side plate member 6. The right side plate member 5 and the left side plate member 6 extend perpendicular to the rear reinforcing plate 23. That is, the angle between the right side plate member 5 and the rear reinforcing plate 23, and the angle between the left side plate member 6 and the rear reinforcing plate 23 are right angles. The right side plate member 5 and the left side plate member 6 face each other and are parallel to each other. The core rod support portion 4 includes two plate members, and the right plate member 5 and the left plate member 6 are each made up of two plate members. The right side plate member 5 is made up of a first right side plate member 5a and a second right side plate member 5b, and the left side plate member 6 is made up of a first left side plate member 6a and a second left side plate member 6b. The rear reinforcing plate 23 is provided on the rear surface of the core rod support portion 4, between the right side plate member 5 and the left side plate member 6, and comprises two plate members (a first rear reinforcing plate 23a and a second rear reinforcing plate 23b) (see Figures 2 and 4). The second rear reinforcing plate 23b has a through-hole 24 formed in the center of its width, through which a string-like body 22a, which is the transmission part 22, is inserted. The string-like body 22a is inserted through the through-hole 24 and is inserted between the first rear reinforcing plate 23a and the second rear reinforcing plate 23b (see FIG. 2). The core rod support portion 4 is fixed to the back plate 17 by an L-shaped metal fitting 18 . Two L-shaped brackets 18 are used. The first L-shaped bracket 18 is fastened to the first right side plate member 5a and the back plate 17 with a screw 18a. The second L-shaped bracket 18 is fastened to the first left side plate member 6a and the back plate 17 with a screw 18a. In this way, the core rod support part 4 is attached to the back plate 17.

[0024] (Configuration in which the core rod support portion 4 supports the core rod 2) The configuration in which the core rod support portion 4 supports the core rod 2 will be described with reference to Figure 7. Figure 7 is a diagram for explaining the configuration in which the core rod 2 of the toilet paper holder 10 is supported by magnetic force. Figure 7(a) relates to this embodiment, and Figure 7(b) relates to another embodiment. As shown in FIG. 7(a), the permanent magnet 21 includes a right first magnet 21a, a right second magnet 21b, a left first magnet 21c, and a left second magnet 21d.

[0025] 7(a), the first right-side plate member 5a is sandwiched between the first right-side magnet 21a and the second right-side magnet 21b at the support region 9 of the right-side plate member 5. That is, the second right-side magnet 21b is sandwiched between the two plate members (the first right-side plate member 5a and the second right-side plate member 5b) at the support region 9 of the right-side plate member 5. The support region 9 refers to a region of the core rod support portion 4 that is close to both ends of the core rod 2 when the core rod 2 is supported by the core rod support portion 4, and there is one support region 9 on each of the right-side plate member 5 and the left-side plate member 6. The first right magnet 21a and the second right magnet 21b are installed so that the magnetic poles of the surfaces facing each other have different polarities. That is, on the surfaces facing each other, if the first right magnet 21a has a north pole, the second right magnet 21b has a south pole, and if the first right magnet 21a has a south pole, the second right magnet 21b has a north pole. The right metal part 30 attached to the right end of the core rod 2 is attracted by the magnetic forces of the first right magnet 21a and the second right magnet 21b and is supported at the support part 9 of the right side plate member 5.

[0026] 7(a), the first left-side plate member 6a is sandwiched between the first left-side magnet 21c and the second right-side magnet 21d at the support portion 9 of the left-side plate member 6. That is, the second left-side magnet 21d is sandwiched between the two plate members (the first left-side plate member 6a and the second left-side plate member 6b) at the support portion 9 of the left-side plate member 6. The first left magnet 21c and the second left magnet 21d are installed so that the magnetic poles of the surfaces facing each other have different polarities. That is, on the surfaces facing each other, if the first left magnet 21c has a north pole, the second left magnet 21d has a south pole, and if the first left magnet 21c has a south pole, the second left magnet 21d has a north pole. The left metal part 31 attached to the left end of the core rod 2 is attracted by the magnetic forces of the first left magnet 21c and the second left magnet 21d and is supported at the support part 9 of the left plate member 6.

[0027] In a configuration in which the core rod support part 4 supports the core rod 2, by using the above-mentioned configuration, the core rod support part 4 can support the core rod 2 even if the core rod 2 is inverted. Therefore, the user can attach the core rod 2 to the core rod support part 4 without worrying about the orientation of the core rod 2.

[0028] (Another configuration in which the core rod support portion 4 supports the core rod 2) The configuration in which the core rod support portion 4 supports the core rod 2 is not limited to the form shown in FIG. 7(a), but may be another embodiment shown in FIG. 7(b). 7(b), the core rod 2 is provided with permanent magnets 32, 33, and metal portions 34, 35 are provided at the support portion 9 of the core rod support portion 4. Specifically, the right-side permanent magnet 32 ​​is provided at the right end portion of the core rod 2, and the left-side permanent magnet 33 is provided at the left end portion of the core rod 2. The right-side metal portion 34 is provided at the support portion 9 of the first right-side plate member 5a of the right-side plate member 5, and the left-side metal portion 35 is provided at the support portion 9 of the first left-side plate member 6a of the left-side plate member 6. The right permanent magnet 32 ​​attached to the right end of the core rod 2 is attracted by the magnetic force between it and the right metal part 34 and is supported at the support part 9 of the right plate member 5 . The left permanent magnet 33 attached to the left end of the core rod 2 is attracted by the magnetic force between it and the left metal part 35 and is supported at the support part 9 of the left plate member 6 . 7(b), in which the core rod support part 4 supports the core rod 2, the core rod support part 4 can support the core rod 2 even when the core rod 2 is inverted, similar to the configuration shown in Fig. 7(a). Therefore, the user can attach the core rod 2 to the core rod support part 4 without worrying about the orientation of the core rod 2.

[0029] (Regarding the retaining plate 12) The pressing plate 12 presses the toilet paper 1 from above. The tip of pressure plate 12 is equipped with a cutting blade (not shown) for cutting toilet paper 1. Tip 12d of pressure plate 12 refers to one side of the periphery of pressure plate 12 on the side where toilet paper 1 is pulled out (see Figure 4). The pressure plate 12 is a rectangular thin plate, and is provided with a right protrusion 12a and a left protrusion 12b on both the left and right ends of the rear end 12e of the pressure plate 12 (see FIG. 4). The rear end 12e of the pressure plate 12 refers to the side of the periphery of the pressure plate 12 opposite the side from which the toilet paper 1 is pulled out, and is the side facing the front end 12d of the pressure plate 12 (see FIG. 4). The right protrusion 12a is inserted into a right elongated hole 25 (see Figures 2, 5, 8, and 9) formed in the second right plate member 5b of the right plate member 5, and moves back and forth along the extension direction of the right elongated hole 25. The left protrusion 12b is inserted into a left elongated hole 26 (see FIGS. 2 and 9) formed in the second left plate member 6b of the left plate member 6, and moves back and forth along the extension direction of the left elongated hole 26. A locking portion 12c is provided at the center in the width direction of the lower surface of the presser plate 12 (see FIGS. 2, 4, and 9). An end of a string-like body 22a (described later) which is the transmission portion 22 is tied to the locking portion 12c. 2, 5, 8, and 9, the right oblong hole 25 is formed in the second right plate member 5b of the right plate member 5. The right oblong hole 25 is formed in a straight line, and slopes obliquely upward as it extends in the opposite direction to the direction in which the toilet paper 1 is pulled out. 2 and 9, the left elongated hole 26 is formed in the second left plate member 6b of the left plate member 6. The left elongated hole 26 is formed in a straight line, and slopes obliquely upward as it extends in the opposite direction to the direction in which the toilet paper 1 is pulled out.

[0030] A right biasing member 27 and a left biasing member 28 are provided to bias the pressure plate 12 in the direction in which the toilet paper 1 is pulled out (see FIGS. 2, 4, and 9). The right-side biasing member 27 and the left-side biasing member 28 restore the presser plate 12, which has moved in the direction opposite to the direction in which the toilet paper 1 is pulled out, to its original position. The right-side biasing member 27 and the left-side biasing member 28 are rubber bands, which are elastic and made of rubber and formed in a ring shape. The right-side biasing member 27 spans between the right-side support pillar 7 formed in the gap between the first right-side plate member 5a and the second right-side plate member 5b of the right-side plate member 5 and the right-side protrusion 12a of the pressing plate 12. The right-side biasing member 27 is disposed in a gap formed inside the right-side plate member 5. The left-side biasing member 28 spans between the left-side support pillar 8 formed in the gap between the first left-side plate member 6a and the second left-side plate member 6b of the left-side plate member 6 and the left-side protrusion 12b of the pressing plate 12. The left-side biasing member 28 is disposed in the gap formed inside the left-side plate member 6.

[0031] (Regarding the air discharge section 13) The air discharge unit 13 blows air 40 (see FIG. 8) onto the end 1b of the toilet paper 1 from below to above the side where the toilet paper 1 is pulled out, thereby lifting the end 1b of the toilet paper 1. The side where the toilet paper 1 is pulled out is the side where the user of the toilet paper holder 10 is present, which is the front side of the paper in FIG. 3. The opening 13c of the air discharge unit 13 is directed upward or diagonally upward, and the air 40 blown out by the air discharge unit 13 flows upward or diagonally upward. The air discharge unit 13 has a plurality of nozzle units connected to the air pump unit 14. The toilet paper holder 10 has two nozzle units, a first nozzle unit 13d and a second nozzle unit 13e, but the number is not limited to two and may be one, or three or more. There are multiple nozzles, and the multiple nozzles are arranged along the width direction of the toilet paper 1. The opening 13c of the air discharge portion 13 is widened along the width direction of the toilet paper 1 and is flattened. The nozzle portion is the open end of the tube 20, which will be described later. The tube 20 is made of a resin such as vinyl chloride and is soft and flexible, so the shape of the opening of the nozzle portion (first nozzle portion 13d and second nozzle portion 13e) can be deformed to match the flattening of the air discharge portion 13. As shown in FIG. 4, the openings of the first nozzle portion 13d and second nozzle portion 13e are deformed into an elliptical shape to match the flattening of the opening 13c of the air discharge portion 13. Air discharge section 13 is formed by stacking two identical rectangular plates (first plate 13a and second plate 13b) with a predetermined gap between them. Short sides 13f and 13g of the rectangle of air discharge section 13 are closed to prevent air leakage (see FIG. 4). The opening 13c of the air discharge section 13 has a flat shape that spreads along the width of the toilet paper 1, so that the air 40 spreading in the width direction of the toilet paper 1 is blown from bottom to top toward the end 1b of the toilet paper 1, allowing the end 1b of the toilet paper 1 to float by efficiently using the amount of air 40.

[0032] (Regarding the air pump unit 14) The air pump unit 14 supplies air to the air discharge unit 13 . The air pump section 14 is commercially available under the name of a bellows pump or an air step pump, and its volume changes as the bellows-structured section 14a expands and contracts, expelling air 40 as the bellows-structured section 14a contracts, and drawing in air as the bellows-structured section 14a expands. The air pump section 14 can continuously discharge air 40 by repeatedly expanding and contracting the bellows-structured section 14a. The air pump unit 14 is placed on the upper surface of the bottom plate 16 . The air pump unit 14 and the air discharge unit 13 are connected by a tube 20 , and the air discharged by the air pump unit 14 reaches the air discharge unit 13 through the tube 20 . The tube 20 is bifurcated midway into a bifurcated right portion 20a and a bifurcated left portion 20b. The end of the bifurcated right portion 20a becomes the second nozzle portion 13e, and the bifurcated left portion 20b becomes the first nozzle portion 13d. The air in the air pump portion 14 is divided into the bifurcated right portion 20a and the bifurcated left portion 20b and discharged from the second nozzle portion 13e and the first nozzle portion 13d. The air pump part 14 expands from the contracted state when pressed by the external force receiving part 15 due to the restoring force of the contracted bellows structure part 14a which tries to return to its original shape, and returns to its original shape while taking in external air.

[0033] (Regarding the external force receiving portion 15) The external force receiving portion 15 discharges air from the air pump portion 14 when pressed by the air pump portion 14 . External force receiving portion 15 has a thin rectangular shape and is fixed to bottom plate 16 via hinges 36. Therefore, the angle formed between external force receiving portion 15 and bottom plate 16 is variable within a predetermined angle range. The external force receiving portion 15 is provided with a foot rest portion 15a, and the air pump portion 14 is pressed when the user steps on it with his or her foot. As shown in FIG. 1, the position of the foot rest 15a in the external force receiving portion 15 is indicated by a foot mark. The external force receiving portion 15 and the pressing plate 12 are connected by a string-like body 22 a which is a transmission portion 22 . External force receiving portion 15 is pressed down when the user steps on it with their foot, and returns to its original position due to the restoring forces of right-side biasing member 27 and left-side biasing member 28. Right-side biasing member 27 and left-side biasing member 28 return presser plate 12 to its original position due to their restoring forces, and external force receiving portion 15, which is connected to presser plate 12 by string-like body 22a, returns to its original position together with presser plate 12, which returns to its original position.

[0034] (Transmission part 22: string-like body 22a) The transmission unit 22 transmits the action of the external force receiving unit 15 that presses the air pump unit 14 to the pressure plate 12, and moves the pressure plate 12 in the direction opposite to the direction in which the toilet paper 1 is pulled out. The transmission part 22 is a string-like body 22a that connects the external force receiving part 15 and the pressure plate 12, and the operation of the external force receiving part 15 that presses down on the air pump part 14 moves the pressure plate 12 in the opposite direction to the direction in which the toilet paper 1 is pulled out. The string-like body 22 a has one end tied to the locking portion 12 c of the pressing plate 12 and the other end tied to the locking portion b of the external force receiving portion 15 .

[0035] (Explanation of operation) The operation of the toilet paper holder 10 will be described with reference to Figure 8. Figure 8 is a diagram for explaining the operation of the toilet paper holder 10. Figure 8(a) shows the state of the toilet paper holder 10 before the external force receiving portion 15 is stepped on by the user's leg, and Figure 8(b) shows the state of the toilet paper holder 10 after the external force receiving portion 15 is stepped on by the user's leg. When the user's leg steps on external force receiving portion 15 and external force receiving portion 15 is pressed down (arrow 41), string-like body 22a is pulled downward (arrow 42). Then, string-like body 22a tied to locking portion 12c pulls presser plate 12 diagonally upward (arrow 43) while resisting the biasing forces of right-side biasing member 27 and left-side biasing member 28. When the user's foot pressure on external force receiving portion 15 is removed, presser plate 12 returns to its original position due to the restoring forces of right-side biasing member 27 and left-side biasing member 28. Then, string-like body 22a tied to locking portion 12c of presser plate 12 pulls up external force receiving portion 15 and returns it to its original position. When external force receiving portion 15 is pressed down, air pump portion 14 contracts and air 40 is blown up from air discharge portion 13 (arrow 44).

[0036] Each time the user's foot steps on external force receiving portion 15, pressure plate 12 is moved in the opposite direction to the direction in which toilet paper 1 is pulled out (to the right in FIG. 8), and at the same time air 40 is blown up from air outlet 13. At this time, end 1b of toilet paper 1 becomes longer, and the portion of toilet paper 1 blown up by air 40 becomes longer, making it easier for the user to grasp. Therefore, when the user wants to use the toilet paper 1, the end 1b of the toilet paper 1 blown up by the air 40 becomes longer, making it easier for the user to grasp the toilet paper 1. When the user does not need the toilet paper 1, the end 1b of the toilet paper 1 becomes shorter, and therefore less of the toilet paper 1 is exposed to the external environment, preventing the toilet paper 1 from becoming dirty or damaged, and allowing the user to use clean toilet paper 1.

[0037] (Other embodiments of the transmission unit 22: air cylinders 51 and 52) Next, another embodiment of the transmission part 22 will be described with reference to Fig. 9. Fig. 9 is a diagram for explaining another embodiment of the transmission part 22 of the toilet paper holder 10. Figure 9(a) shows the state of the toilet paper holder 10 before the external force receiving portion 15 is stepped on by the user's leg, and Figure 9(b) shows the state of the toilet paper holder 10 after the external force receiving portion 15 is stepped on by the user's leg. The transmission part 22 of the toilet paper holder 10 shown in Fig. 9 employs air cylinders 51, 52 instead of the string-like body 22a. That is, the toilet paper holder 10 shown in Fig. 9 has the right air cylinder 51 arranged in a position parallel to the right biasing member 27, and the left air cylinder 52 arranged in a position parallel to the left biasing member 28. The transmission part 22 of the toilet paper holder 10 shown in Figure 9 is air cylinders 51, 52 that receive air from the air pump part 14 and push out piston rods 53, 54, and the piston rods 53, 54 pushed out by the air cylinders 51, 52 move the pressure plate 12 in the direction opposite to the direction in which the toilet paper 1 is pulled out (arrow 55). The right air cylinder 51 receives air supplied from the air pump unit 14 and pushes out the right piston rod 53 . The left air cylinder 52 receives air from the air pump unit 14 and pushes out the left piston rod 54 .

[0038] The right air cylinder 51, which is the transmission unit 22, is installed in parallel with the right biasing member 27. Specifically, the right air cylinder 51 is installed between the right support column 7 and the right protrusion 12a. When the right air cylinder 51 pushes out the right piston rod 53, the right protrusion 12a is pushed up by the right piston rod 53. The left air cylinder 52, which is the transmission unit 22, is installed in parallel with the left biasing member 28. Specifically, the left air cylinder 52 is installed between the left support column 8 and the left protrusion 12b. When the left air cylinder 52 pushes out the left piston rod 54, the left protrusion 12b is pushed up by the left piston rod 54. That is, the right piston rod 53 and the left piston rod 54 push up the right protrusion 12a and the left protrusion 12b, and move the pressure plate 12 in the opposite direction (arrow 55) to the direction in which the toilet paper 1 is pulled out, against the biasing force of the right biasing member 27 and the left biasing member 28. When the user's foot pressure that has been received by the external force receiving portion 15 is removed, the presser plate 12 returns to its original position due to the restoring forces of the right-side biasing member 27 and the left-side biasing member 28. The right-side piston rod 53 and the left-side piston rod 54 are pushed back by the right-side protrusion 12a and the left-side protrusion 12b, and enter the right-side air cylinder 51 and the left-side air cylinder 52, returning to their original positions.

[0039] Each time the user's foot steps on external force receiving portion 15, pressure plate 12 is moved in the opposite direction to the direction in which toilet paper 1 is pulled out (the direction of arrow 55), and at the same time air 40 is blown up from air outlet 13. At this time, end 1b of toilet paper 1 becomes longer, and the portion of toilet paper 1 blown up by air 40 becomes longer, making it easier for the user to grasp.

[0040] (Regarding toilet paper refills) Refilling the toilet paper 1 into the toilet paper holder 10 will be described with reference to Figure 10. Figure 10 is a diagram for explaining refilling the toilet paper 1 into the toilet paper holder 10. When the toilet paper 1 is used up, the presser plate 12 is lifted to remove the core rod 2 from the toilet paper holder 10. Next, with the core rod 2 inserted into the hole 1a of the new toilet paper 1, the new toilet paper 1 is placed inside the toilet paper holder 10. With the core rod 2 supported by the core rod support part 4, the new toilet paper 1 is held inside the toilet paper holder 10.

[0041] According to the toilet paper holder 10 of the above-described embodiment, each time the user's foot steps on the external force receiving portion 15, the pressure plate 12 moves in the opposite direction to the direction in which the toilet paper 1 is pulled out, thereby extending the end 1b of the toilet paper 1, and the end 1b of the toilet paper 1 is blown up by the air 40 blown up from the air outlet portion 13, so that the portion of the toilet paper 1 that the user attempts to grasp becomes longer, allowing the user to grasp the toilet paper 1 easily and quickly.

[0042] Furthermore, according to the toilet paper holder 10 of the above embodiment, the user presses the external force receiving portion 15 with his / her leg, so there is no risk of the user getting his / her hands dirty.

[0043] Furthermore, according to the toilet paper holder 10 of the above-described embodiment, the air pump section 14 has a bellows structure, so that the contracted air pump section 14 returns to its original shape due to the restoring force of the bellows structure portion 14a, and therefore there is no need to separately provide a special configuration for restoring the shape of the air pump section 14.

[0044] Furthermore, according to the toilet paper holder 10 of the above-described embodiment, the core rod 2 is supported inside the core rod support portion 4 by the magnetic force of the permanent magnet 21, so that the risk of deterioration and damage to the support portion 9 can be reduced even if the core rod 2 is repeatedly attached and detached.

[0045] The present invention is not limited to the toilet paper holder 10 according to the above-described embodiment, and can be implemented in various other modified or applied examples as long as they do not deviate from the gist of the present invention as described in the claims.
