Description

Roll material holder

The present invention relates to a roll material holder that holds a product to be cut out and used by rolling in roll form (hereinafter referred to as a roll-like product) and pulls out from the takeout part by use for cutting out. More specifically, the present invention relates to the improvement of the extraction section for pulling out and cutting out the roll material of the roll material holder by the amount of use.

Conventionally, there is a roll material holder disclosed in, for example, Patent Document 1 as a roll material holder that can be cut out with one hand and arranged so as to be separated from the roll material main body so that the rolled material tip after cutting can be easily pulled out next time use. .

The roll paper holder described in Patent Document 1 includes a holder main body including a back plate portion and left and right side plate portions, a roll support portion rotatably supporting the roll paper, and a protrusion pressing the upper surface of the roll paper A holding plate portion having a holding plate portion, wherein a placement holding portion for placing paper from roll paper, a second holding plate portion holding the paper on the setting holding portion, and a front end portion of the second holding plate portion A receiving part connected to the front side of the mounting part and a front plate part placed on the receiving part, and a holding part which holds the front plate part pivotably as a vertical swing fulcrum And a cutting blade for cutting the paper from the loading tray, and when the paper from above the loading ridge is lifted by hand and applied to the cutting blade, the rotation of the roll paper and the paper Stop feeding and hold the paper in one hand And so as to reliably and easily cut.

JP, 2016-129597, A

However, in the device described in Patent Document 1, the front plate portion that holds the paper at the time of cutting is further forward of the placement bar disposed in front of the roll material so that the tip end portion of the roll material is easily separated from the roll material body and pulled out easily. In the case of uniform specific gravity, it is necessary to secure the front and back length of the shaft or more on the front side of the shaft. It is necessary to secure a sufficient space in the forward direction of the roll material, and it is difficult to secure the holder so compact that it can be installed even in a narrow space. Also, when the load is applied accidentally from the top of the tip, for example, a large overhang from the back surface may cause a hand to be placed on the upper surface of the front plate, a greater leverage is applied to the main body, The risk of failure such as the falling off of the main body or damage to the mounting wall increases. In addition, it has a structure that requires a total of three axes of rotation: the rotation axis used when cutting out the roll material tip, the rotation axis used for pressing the tip always, and the rotation axis used when setting the roll material The number of parts and the number of manufacturing processes are increasing, which causes cost increase. Furthermore, as a structure, the rotation axis of the front plate portion is not a structure that spans the inside of the fixed side portion of the holder body, but is spanned between the inside of the side portion of the holder body and swings itself by the rotation axis. It is further bridged over the first presser plate. In other words, it has a nested structure in which a component that is further pivoted is mounted on a component that is pivoted, so that securing of component strength and assembly accuracy and accompanying cost reduction are not easy.

That is, according to the structure of the roll paper holder described in Patent Document 1, there is a complicated structure with a large number of parts, and it is necessary to adopt a structure projecting considerably in the front direction from the portion accommodating the roll material body. There is a problem of taking a large size and taking place, and a greater risk of failure when a load is applied to the tip of the main body. Moreover, the complicated structure and the increase in the number of parts not only increase the cost but also cause problems such as malfunction and damage because they are fragile as a structural factor and require complicated movements. It contains.

An object of the present invention is to provide a roll material holder which has a simple and compact structure and can be easily operated even with one hand.

In order to achieve the above object, the roll material holder according to claim 1 holds the roll material to be cut out and used by rolling in a roll shape, holds the roll material to be used, and pulls out from the takeout part to use it In the holder, a roll material support shaft which engages with the central hollow portion of the roll material to rotatably support the roll material body, a blade for cutting out a portion to be used from a portion pulled out from the roll material body, roll material A flap which is rotatably supported about a rotation axis parallel to the support axis and has a center of gravity behind the rotation axis and is always biased in one direction by its own weight, and a roll material And a flap receiver for placing a portion pulled out from the roll material main body and sandwiching it with the flap, the flap being a row drawn from a gap between the flap receiver and the flap receiver. When the material's cutting site is pressed against the end opposite to the end that is pressed against the flap receiver and pulled toward the blade, it rotates toward the flap receiver and rolls between the flap receiver and the roll material The part pulled out from the main body is held between them and fixed, and the part pulled out of the roll material is applied with tension and applied to the blade so as to be cut off.

The roll material holder according to the second aspect of the present invention has a rotating shaft at the rear end portion, swings and rotates around the rotating shaft, and directly contacts the roll material main body to reversely rotate the roll material main body. Of the roll material body presser, while the edge part around the rotation shaft of the roll material body presser functions as a flap receiver, while the outer surface of the roll material body presser is pulled out from the roll material body of the roll material. It is made to function as an uncut part reception part which receives and supports the uncut part between the part pinched between the flap and the flap receiver of the cut part to the blade.

In the roll material holder according to the third aspect of the present invention, the flap and the flap receiver are in contact with each other at the contact portion, and when the roll material is cut out, the relief shape is fitted to form the gap between the flap and the flap receiver. The part pulled out from the passing roll material main body is held between the concavo-convex shape.

In the roll material holder according to the invention of claim 4, the flaps shield the upper side of the roll material body.

Furthermore, the roll material holder according to the invention of claim 5 supports the both ends of the curved plate-like saucer portion and the saucer portion to rotatably support the saucer portion centering on the roll material support shaft of the holder main body. It has a roll material saucer which has a pair of left and right arm parts, and the rotation of the saucer part is fixed under the flap, and the outer surface of the saucer part is the part of the roll material pulled out from the roll material body It is made to function as a left-off receiver that supports the left-to-be-held portion that holds the left-to-be-cut off portion pulled out from the roll material between the flap receiver and the blade. By doing this, the tray portion is suspended from the roll material support shaft, and the inner surface of the tray portion is made to function as a temporary placement portion of the roll material, thereby assisting the roll material replacement operation.

According to the roll material holder of claim 1, the uncut portion of the roll material drawn out from the gap between the flap and the flap receiver is pressed against the end opposite to the end portion pressed against the flap receiver. And when it is pulled toward the blade, it rotates toward the flap receiver and clamps the part pulled out from the roll material body between the flap receiver and clamps it, applying tension to the pulled out part of the roll material Since the roll material is put into contact with the blade and cut out, the roll material can be pulled out and cut out by the amount used even with one hand, and the structure is also simple and compact. In addition, since the tip of the roll material can be set in the space between the flap receiver and the flap receiver generated by rotating the flap in the opposite direction by a simple operation of dropping the tip of the roll material from the top, the parts such as the flap can be removed It can be operated easily with one hand. Furthermore, since the uncut portion of the roll material sandwiched between the flap and the flap receiver is always pressed against the flap receiver by the rotational force of the flap's own weight and held, the uncut portion is directed to the roll material body side Retraction can be suppressed, and the uncut region exists at a fixed position in a state of being separated from the roll material body, and the tip can be easily pulled out with one hand even at the next use.

Further, according to the invention of claim 2, since the flap receiver and the uncut portion receiver and the roll material body presser can be combined by one component to make the structure simple and compact, the number of components is not increased. It is possible to prevent reverse rotation of the roll material body and to prevent the uncut portion of the roll material from being pulled back, thereby making it easier to pull out and cut the next roll material. In addition, since the uncut portion of the roll material is supported by and supported by the uncut portion receiving portion on the outer surface of the roll material body presser, the uncut portion can be easily picked while being pressed against the uncut portion receiving portion.

Further, according to the invention of claim 3, when cutting off the roll material, since the unevenness of the flap and the flap receiver is fitted, the portion of the roll material drawn from the roll material main body is the flap and the flap receiver. The clamping force between the roll material is further increased to fix the roll material, and even after cutting, the uncut portion of the roll material prevents the roll material body from pulling back the leading end more firmly by increasing the frictional force due to uneven fitting. Can do. The strength of the presser and the function of suppressing the reverse rotation of the roll after cutting can be enhanced.

Furthermore, according to the fourth aspect of the present invention, the flaps cover the roll material body, protect the roll material from water droplets and dust from above, and contribute to maintaining the hygiene of the roll material.

Furthermore, according to the invention of claim 5, after the roll material is passed through the roll material support shaft and placed on the saucer portion of the roll material saucer, the tip end is pulled out and dropped on the near side of the saucer portion. The roll material can be set in the holder body with the uncut portion drawn out between the flap receiver and the flap simply by rotating the tray to the use position. Accordingly, the roll material can be set in the holder body very easily. Moreover, the roll holder can be made compact without impairing the operability at the time of mounting the roll material.

Hereinafter, the configuration of the present invention will be described in detail based on an embodiment shown in the drawings. In the present specification, the three axial directions perpendicular to each other are the vertical direction (Z-axis) unless otherwise specified, in the longitudinal direction (Y-axis), the left-right direction (X-axis) and the vertical direction (Z-axis) orthogonal to each other. The term “front side” or “outside” means the left side of what is the reference in FIGS. 1 and 2, and the far side or the inside means the right side of what is the reference in FIGS. 1 and 2.

1 and 2 show an example of an embodiment of a roll material holder of the present invention. The roll material holder according to this embodiment is applied to a toilet paper holder, and the toilet paper rolled up in a roll shape (hereinafter referred to as a roll material 1, and in particular, a portion wound in a roll shape is a roll material) A holder main body 4 rotatably holding the main body 1a), a flap 6 and a flap receiver 7 enabling the roll material 1 to be cut off, and the roll material main body 1a held by the holder main body 4 is used It pulls out only for a minute and cuts it and uses it. In addition, the holder main body 4 of this embodiment is attached and used for the wall surface etc. of a structure.

The holder main body 4 is, for example, a plane-viewed co-shaped frame configured by a back surface member 2 attached to a structure or a wall surface, and left and right side surface members 3 extending forward from left and right end portions of the back surface member 2 A roll material support shaft 5 is provided, which stands vertically (for example, parallel to the back member 2) with respect to the side member 3 from the both side members 3 inward. The roll material support shaft 5 rotatably supports the roll material by being inserted into the central hollow portion 1c of the roll material main body 1a. For example, the roll material main body 1a is lowered in the internal space of the holder main body 4 When inserted from the side, it is pushed down by the roll material body 1a to allow passage of the roll material body 1a, and when the roll material body 1a is completely accommodated in the internal space of the holder body 4, it is automatically erected by the force of a built-in spring. Then, it is a pivotable shaft which jumps into the central cavity 1c of the roll material body 1a.

The holder main body 4 is provided with a flap receiver 7 on which a portion peeled off from the roll material main body 1a or a portion left after being cut (hereinafter, these are collectively referred to as uncut region 1b) is placed On the other hand, it is provided with a flap 6 which is always pressed by its own weight and sandwiches the uncut part 1b between the flap receiver 7 and the flap receiver 7 so that the uncut part 1b is pulled out from the gap between the flap 6 and the flap receiver 7 It is provided. In the present embodiment, a flap 6 and a flap receiver 7 serving as a takeout portion are provided on the upper front side of the holder main body 4.

In the case of this embodiment, the flap 6 is made of, for example, a flat plate having a rectangular shape in a plan view as shown in FIG. 2, and the acute angled tip edge doubles as the blade 9 to enable cutting of the roll material 1. In the case of the present embodiment, the flaps 6 are disposed horizontally in the space between the left and right side members 3 of the holder body 4 and parallel to the roll material support shaft 5 (in other words, the rotation center of the roll material body 1a) It is rotatably supported around a rotary shaft (hereinafter referred to as a flap shaft 6a). The flap 6 is disposed at a position not interfering with the roll material body 1 a housed in the internal space of the holder body 4 and at a position where the tip of the roll material body 1 a can be easily taken out. For example, in the case of the present embodiment, as shown in FIG. 1, the flap 6 is a roll material on the near side of the roll material support shaft 5 and above the roll material main body 1 a supported by the roll material support shaft 5. It is provided in the position which does not interfere with the main body 1a.

Here, the arrangement interval between the flap receiver 7 and the flap 6 is, for example, an interval between the flap shaft 6a and the flap receiver 7 to form a gap for drawing out at least the tip of the roll material or uncut portion 1b. The user's finger tip can be inserted freely and there is a gap, and when the flap 6 is pressed against the flap receiver 7, the uncut part 1b is sandwiched and fixed between the flap 6 and the flap receiver 7 It is in a positional relationship that makes it possible to prevent material withdrawal or reversion, and it is equipped so as to always press down from above with the flap 6 with the uncut part 1 b placed on the flap receiver 7. . That is, the center of gravity of the flap 6 is set on the back side of the flap shaft 6a, and the holder main body 4 can rotate so that the flap 6 is always biased in one direction, ie, the flap receiver 7 by its own weight. It is supported. Then, from the gap between the flap 6 and the flap receiver 7, the leading end pulled out from the roll material body is taken out.

The flaps 6 are integrally provided with flap shafts 6a projecting in the width direction (X-axis direction in FIG. 2) on both sides facing the side members 3 of the holder body 4, for example. It is rotatably supported by fitting the flap shafts 6a on both sides into bearing recesses, for example, bearing grooves 8 provided in each of the above. Of course, the flap shaft 6a may be a shaft separate from the flap 6, for example, a single rotation shaft passing through the flap 6 in the width direction, and the bearing grooves 8 of the left and

right side members

3, 3 of the holder body 4 The flaps 6 are rotatably supported by fitting them to each other. The bearing groove 8 accommodating the flap shaft 6a has, for example, a round hole sized to rotatably support the flap shaft 6a, a triangular long groove facilitating movement of the flap shaft 6a, and a constricted portion. The flap shaft 6a inserted in the long groove is supported by the round hole portion by passing the narrow portion.

In the case of the present embodiment, the blade 9 is formed by the sharp edge of the flap 6, but it is not particularly limited to this. For example, a burr protruding downward so as to be orthogonal to the flap 6 as shown in FIG. It may be formed by a (burr) shaped edge. It is preferable to cause the blade 9 to project downward because it is cut off with a light force because there is little slip (slip) when cutting off the portion pulled out from the roll material body 1a. Further, as shown in FIG. 13, the blade 9 may be formed so as to project upward or frontward, and in some cases, is separated from the tip end edge of the flap 6 to the far side from the flap shaft 6a. It may be formed to project on the lower surface of the flap. Further, the blade 9 is not limited to one integrally formed with the flap 6 and may be formed separately as a blade 9 made of soft resin such as EVA resin (ethylene-vinyl acetate copolymer resin) in a saw blade shape The formed separate part may be fixed to the flap 6 by adhesion, welding or the like.

Furthermore, as shown in FIG. 10, the blade 9 which is separated from the flap 6 and formed independently is provided on the side of the roll material holder 4 so as to be disposed in front of the flap 6 (front side) good. For example, the blade 9 of another part may be installed and fixed so as to straddle the side walls 3 of the roll material holder 4. In this case, although the blade 9 of another part may be always exposed, it may be movable so that the blade 9 is relatively exposed when the portion pulled out from the roll material body 1a is pressed.

In the case of the present embodiment, the flap 6 is formed in a flat plate shape as a whole, but is not particularly limited thereto. For example, although not shown, the region on the front side of the flap shaft 6a is directed downward. It may be curved. In this case, the blade 9 formed at the tip end edge of the flap 6 is directed downward, which makes it difficult for the user to touch the eye and can relieve fear and anxiety with the blade 9. Even with a safe blade, there are many people who feel the psychological fear or discomfort of touching the blade, and those who show a rejection reaction to the protrusion of the blade toward the front. It is desirable as a consideration for such users. In addition, it is possible to make the force easy to be applied at a right angle by cutting away when sliding off the part pulled out from the roll material main body 1a, and it is possible to cut by a light force.

The flap receiver 7 sandwiches the uncut portion 1b between itself and the flap 6 only with the pressing force of the flap 6 by the weight of the flap 6 at stand-by time when the roll material is not cut off, and the flap 6 near the flap shaft 6a at the time of cutting. By rotating in the direction (clockwise direction in FIG. 1) in which (the tip end edge side) is lifted, the unleft portion 1b between the flap 6 and the flap 6 is pinched more strongly than in the standby state. That is, at the time of cutting of the roll material, it is necessary to fix the uncut portion 1b, and at other times, it is preferable that a slight frictional resistance to such an extent that the unrolled portion 1b can be prevented. Therefore, the flap receiver 7 sandwiches and fixes the uncut portion 1b with the flap 6, and the roll material 1 tends to be pulled out when the uncut portion 1b is pressed against the blade 9 and pulled and separated. To prevent tensioning by preventing the extension or return of the And, at the time of stand-by after the cutting of the roll material, it functions as the one preventing the reversion of the uncut region 1b by the weight of the flap 6.

Here, the flap receiver 7 is a fixed plate having a ridge portion (contact portion 11) as shown in FIG. 4 even with the shaft member as shown in FIG. No matter what kind of system it is. On the other hand, in the case of the axial flap receiver 7 as shown in FIG. 1, the contact position between the flap 6 and the flap receiver 7 with the uncut portion 1 b from the blade 9 to the flap receiver 7 behind the blade 9. That is, it hangs down near the position where the uncut portion 1b is held. On the other hand, as shown in FIG. 4, in the case of the plate-like flap receiver 7, the left uncut portion 1b is an inclined surface on the front side of the contact position between the flap 6 and the flap receiver 7 By being supported on the portion 10), the uncut portion 1b can be picked up on the front side of the case of the axial flap receiver 7. In addition, since the uncut portion 1 b can be picked up while being pressed against the uncut receiving portion 10, picking becomes easy. That is, from the viewpoint of the ease of gripping the uncut portion 1b, the plate-like flap receiver 7 as shown in FIG. 4 in which the uncut receiver 10 is present on the front side of the contact position between the flap 6 and the flap receiver 7. It is preferable to use In this case, the flap receiver 7 is, for example, a metal plate or a resin plate bent in a substantially mountain shape, and is provided so as to sandwich the uncut portion 1b as a contact portion 11 to the flap 6 at a bending point (ridge line) portion There is. The plate-like flap receiver 7 is not particularly required on the back side of the contact portion 11 to the flap 6, so for example, the uppermost portion of the rear end of the inclined plate is the contact portion 11 to the flap and the front side is left behind It may be made to function as the receiving unit 10. The plate-like flap receiver 7 is fixed to both side members 3 of the holder body 4 and its inclination and the like do not change. Whether it is rod-like or plate-like, the flap receiver 7 is attached at a position where it can contact the lower surface of the flap shaft 6a of the flap 6 attached to the upper front of the holder body 4 to prevent the flap 6 from rotating. It is done.

Here, the position of the flap shaft 6a may be on the near side of the center of gravity of the flap 6 and on the far side of the end (outside end) on the front side of the flap 6, and is limited to a specific position. Absent. For example, in the embodiment of FIG. 1, the flap shaft 6a is provided on the front side of the middle (center of gravity position) of the longitudinal length of the flap 6 so that the center of gravity is disposed on the back side of the flap shaft 6a. However, if a weight or the like is incorporated, the setting of the center of gravity position can be easily changed, so the position of the rotary shaft 6a is not limited in relation to the length of the flap in the front-rear direction. That is, in the case of a flap 6 of uniform thickness and specific gravity having a center of gravity at the center, the flap shaft 6a is provided on the near side even at the front of the middle of the longitudinal length of the flap 6 so that the center of gravity position is on the back side. However, as long as the center of gravity itself exists on the back side of the middle of the front and rear lengths of the flap 6, the flap shaft 6a may be provided on the back side of the middle of the front and rear lengths of the flap 6. In some cases, it is also possible to provide the center of gravity of the flap 6 behind the flap receiver 7. As a result, the flap 6 can be turned so as to always tilt with its own weight on the side with the center of gravity centered on the flap shaft 6 a, and the flap 6 can be pressed against the flap receiver 7.

Of course, if the flap shaft 6a is provided as close to the front edge of the flap 6 as possible, the volume of the roll material holder main body 4 is supported while supporting the flap shaft 6a and the back of the flap. Since the distance between the flap receiver 7 and the flap receiver 7 can be increased, it is easy to pass the tip of the uncut portion 1 b through the gap between the flap shaft 6 a and the flap receiver 7. That is, the setting operation of the tip of the roll material with one hand can be performed more easily. Therefore, it is preferable that the flap shaft 6a be provided as close to the front side of the flap 6 as possible.

On the other hand, since the position of the flap receiver 7 is the position where the uncut portion 1b of the roll material hangs down or the start position of the uncut receiver 10, the true position of the roll material support shaft 5 is taken into consideration. It is preferable to be provided near the top.

Further, in the case of the present embodiment, the flap 6 and the flap receiver 7 are provided at substantially the same height as the flap shaft 6 a and the flap receiver 7 in the case of the present embodiment. It is not limited. In an extreme example, for example, as shown in FIG. 9, the flap receiver 7 may be disposed above the flap shaft 6a. That is, the flap shaft 6a is disposed on the front side of the flap receiver 7 and the center of gravity of the flap is disposed on the back side of the flap shaft 6a so that the flap 6 is always pressed against the flap receiver 7 It is good if the force to be generated is in the relation generated by its own weight.

If the flap 6 is a flat plate as shown in FIG. 1 and FIG. 2, the flap receiver 7 is disposed obliquely to the roll material drawing direction on the XY plane to contact the flap 6 and the flap receiver 7 Even when the portion 11 (line holding the uncut portion 1b) is not parallel to the flap shaft 6a, there is no big difference in the function of holding the uncut portion 1b. However, in this case, since the portion pulled out from the roll material body 1a falls along the contact portion 11 as the uncut portion 1b, a situation occurs in which the uncut portion 1b does not face straight ahead. In other words, it is preferable that the flap shaft 6a and the flap receiver 7 be provided so as to maintain a substantially parallel relationship so that the direction of the uncut portion 1b hanging down along the contact portion 11 faces the front. . Further, as for the relationship between the flap axis (fulcrum point) 6 a and the flap receiver (action point) 7, securing parallelism in both the XY plane and the XZ plane is directly linked to the improvement of sharpness.

In the case of this embodiment, in the case of using a shaft as the flap receiver 7 or in the case of using a ridge of a plate folded in a chevron, a portion in contact with the flap 6 of the flap receiver 7 is used. Are also configured as "lines" across the holder body, but in some cases they may be surfaces. For example, in the case of employing the flap receiver 7 of a plate bent in a mountain shape as shown in FIG. 4, the contact area can be increased by making the ridge line portion (contact portion 11) a gentle curved surface with a large radius of curvature, The flat contact portion 11 may be formed by adopting a trapezoidal flap receiver 7 as shown in FIG. In this case, since the frictional resistance when drawing out the part to be cut out from the roll material body 1a is larger than in the case of the shaft-like flap receiver 7, the roll material body 1a is less likely to idle and draw extra due to inertia force. On the other hand, if the frictional resistance increases too much, the roll material is easily broken when pulled out, so the contact between the flap 6 and the flap receiver (shaft or plate) 7 is greater than when cutting out from the roll material body 1a. It is preferable that the frictional resistance be low, and when cutting out, the frictional resistance be higher than when pulling out.

According to the roll material holder of this embodiment configured as described above, the roll material exchange operation can be easily performed without removing the flap 6 and / or the flap receiver 7 from the holder main body 4. For example, as shown in FIG. 3A, when the flap 6 is turned to the front side (for example, 270 ° reverse rotation in the counterclockwise direction) and the back side of the flap 6 is lowered, the flap receiver 7 and the flap Since a gap is generated between the shaft 6 a and the flap 6, the gap can be made to hang down through the portion pulled out from the roll material body 1 a. Thereafter, when the flap 6 is rotated forward (clockwise by 270 °) and the rear end (back) side of the flap 6 is placed on the flap receiver 7 and returned horizontally, between the flap 6 and the flap receiver 7 The part pulled out from the roll material main body 1a hangs down on the front side of the flap receiver 7 as the uncut part 1b in a state where the leading end of the roll material is sandwiched. The setting operation of the roll material to the holder body 4 can be easily performed with one hand.

Then, when the uncut part 1b hanging down on the front side of the flap receiver 7 is picked and pulled on the near side (horizontal direction or diagonally downward direction), the back side of the flap 6 is attached to the flap receiver 7 due to its own weight. Only the necessary amount can be pulled out with a single hand smoothly from the roll material body 1a without a force more than the pressing force acting.

When the necessary amount is pulled out from the roll material main body 1a, when the pulled out portion is lifted upward, in the case of the embodiment shown in FIG. 1, the flap 6 rotates clockwise and the back end of the flap 6 The part is further pressed against the flap receiver 7. As a result, the uncut portion 1b is sandwiched and fixed between the flap 6 and the flap receiver 7, and the uncut portion 1b can not move back and forth.

In this state, if the uncut part 1b is further pulled upward, tension is applied to the uncut part 1b on the front side of the part sandwiched between the flap 6 and the flap receiver 7, and the blade 9 is separated. . As a result, even one hand can be cut out reliably and easily.

Since the uncut part 1b between the blade 9 and the flap receiver 7 is sandwiched between the flap 6 and the flap receiver 7 by its own weight when the trimming is completed, the unrolled part due to reaction at the time of cutting is also possible. It is restrained, and it is not rewound to the roll material body 1a side. Therefore, since the uncut portion 1b of the tip is surely hanging down from the portion of the flap receiver 7 from the portion sandwiched between the flap receiver 7 and the flap 6, the uncut portion 1b can be easily picked up and removed It is easy to pull out the When the flap receiver 7 is formed in a plate shape as shown in FIG. 4 (or in the case of the roll material body presser 14 of the embodiment shown in FIGS. 5 and 6), the contact portion (the contact portion) Since the left uncut part 1b is received and supported by the slope on the front side than the line 11, that is, the left uncut receiving part 10, the finger is pressed against the uncut receiving part 10 so as to easily pick the left untouched part 1b be able to. Therefore, stress does not occur in the work of peeling and pulling out from the roll material body 1a without finding the uncut region 1b.

In this way, it is possible to operate with one hand over the entire process from the setting of the roll material to the cutting operation. Moreover, the setting of the roll material can be easily performed without removing the parts. Furthermore, it is hygienic because it is possible to cut out without touching the unused portion other than the portion to be cut out of the roll material.

According to the roll material holder of the present embodiment configured as described above, the simple structure is as simple as assembling so that two points of the flap 6 and the flap receiver 7 are bridged between the left and right side members 3 of the holder main body 4 Therefore, it is possible to carry out without changing the existing roll material holder, for example, the manufacturing process of the toilet paper holder, the strength and accuracy required for each part, and to easily manufacture an inexpensive and robust holder. . Moreover, since the take-out part can be configured only by the flap 6 and the flap receiver 7, compactness can be realized without taking up a space, a simple structure with a small number of parts can be realized, and robust, easy and inexpensive manufacture is possible. Become.

Also, it is not necessary to add a new shaft function to separate the flap shaft 6a and the flap receiver 7 in order to set the roll-shaped main body 1a, and the flap shaft 6a is also used as a shaft function for roll setting applications A portion pulled out from the roll material body 1a can be easily interposed and set between the flap shaft 6a and the flap receiver 7 without providing a setting shaft. Therefore, it is possible to design compactly and achieve both low cost production such as reduction of the number of parts. In addition, the gap between the flap receiver 7 and the flap 6 is at least a gap that forms a gap for pulling out the tip of the roll material between the flap shaft 6a and the flap receiver 7, preferably freely inserting the user's fingertip. It is only necessary to provide an interval enough to be inserted, and further, since the length from the flap shaft 6a to the end on the front side can be shortened, the occurrence of a significant overhang in the front direction of the holder body 4 is suppressed. Be In addition, since the flaps are hardly turned in the vertical direction and the posture is substantially the same, no special turning space is required in the vertical direction. From this, the mechanism of the taking-out portion by the flap 6 and the flap receiver 7 can be designed to be compact, so that the accommodation in the narrow toilet private room space can be suppressed as well as the existing general holder.

In this roll material holder, since the cutting position is constant, the roll material holder is not affected by the change in the remaining amount (roll diameter) of the roll material body 1a, and the remaining amount of the roll material body 1a decreases. Even if the diameter decreases, stable cutting can be performed and the sharpness is always constant, which is excellent in usability. And since the flap 6 is installed above the roll material main body 1a, the uncut part 1b is easy to visually observe.

5 and 6 show still another embodiment. The roll material holder according to this embodiment is provided with a movable roll material body presser 14 which is in direct contact with the roll material body 1a to prevent the roll material body 1a from being constantly pressed and reversely rotated. The roll material body presser 14 of the present embodiment is not only means for preventing the unrolled portion 1b from being unwound due to reverse rotation of the roll material body 1a, but also the flap receiver 7 and the uncut portion receiving portion 10 And the same. That is, while the cylindrical portion surrounding the rotation shaft 15 of the roll material body presser 14 is used as the flap receiver 7, the outer peripheral surface of the roll material body presser 14 is used as the uncut receiver 10.

The roll material body presser 14 of the present embodiment is always in contact with the outer peripheral surface of the roll material body 1a at the tip end edge and pressed down by its own weight, but it is not particularly limited to this. The portion 19 may be rolled and rolled (curling) to be pressed at a location other than the leading edge 19. That is, it is not limited to the front end edge 19 but always contacts in any area of the back surface of the left uncut receiving part 10 or is not shown, but is reversely directed such that the left uncut receiving part 10 is warped with respect to the roll material main body 1a. It may be curved. Also in this case, as the diameter of the roll material body 1a changes, the contact portion is always in contact by shifting. As a result, since the uncut portion 1b and the portion of the roll material body 1a are simultaneously pressed, the function effectively prevents the reverse rotation of the roll material body 1a.

In the case of the present embodiment, for example, as shown in FIG. 7, the roll material body presser 14 is a holder body 4 by a rotary shaft 15 penetrating a cylindrical portion 17 which also functions as a flap receiver 7 at the base end It is rotatably supported by the bearing grooves 8 of the left and right side wall members 3 of FIG. However, the present invention is not particularly limited to this support structure, and in some cases, it may be rotatably supported by a shaft integrally formed with the roll material body presser 14. Of course, it is needless to say that combining the shaft as the flap receiver 7 and the rotary shaft of the roll material body presser 14 is preferable in terms of structure because the number of parts can be reduced and the structure can be simplified.

The roll material body presser 14 of the present embodiment is formed, for example, in a curved plate shape along the curved surface of the roll material body 1a. That is, the larger the diameter of the roll material main body 1a, the stronger the force to rewind the uncut part 1b by reverse rotation due to reaction at the time of cutting, so the importance of preventing the reverse rotation of the roll material main body 1a becomes higher. . Therefore, it is preferable that the roll material body presser 14 be a curved surface having a curvature and a radius of curvature substantially the same as those of the roll material body 1a at the maximum diameter.

On the other hand, when the remaining amount of the roll material body 1a decreases, the reverse force of the roll material body 1a also becomes weak accordingly, and the importance of the contact of the roll material body presser 14 with the roll material body 1a decreases. Moreover, if the roll material body presser 14 continues to make contact with the roll material body 1a even if the diameter of the roll material body 1a decreases, the tilt of the roll material body presser 14 becomes large, and it approaches the drooping state. Therefore, it is difficult to pick up the left uncut part 1b. In addition, when the roll material body presser 14 hangs vertically, the roll material body presser 14 is not lifted when, for example, the new roll material 1 is to be mounted from the bottom, and therefore the roll material 1 is set with one hand It gets in the way of Therefore, a stopper member, for example, a projection (not shown) for preventing further inclination and sagging of the roll material body presser 14 at a position or an angle at which the presser body for preventing reverse rotation of the roll material body 1a is not necessary or effective The movement of the roll material body presser 14 may be stopped by providing it on the inner surface of at least one or both of the side surface members 3 or the inner surface of the back surface member 2 or the like. For example, when the inclination of the roll material main body holder 14 becomes an angle suitable for picking the uncut part 1b, for example, about 45 degrees, the remaining amount of the roll material main body 1a decreases and the reverse force also becomes weak. Since the degree of importance of the contact to the roll material body 1a is reduced, a projection or the like (not shown) may be provided on the inner wall surface of the side member 3 to stop further inclination of the roll material body presser 14.

Furthermore, by providing a fitting structure of a female type and a male type at the contact portion 11 between the flap 6 and the flap receiver 7, the effect of pressing the remaining uncut portion 1b and preventing rewinding to the roll material body 1a side is further enhanced. It can be enhanced. For example, as shown in FIG. 7, the flap receiver 7 side is formed into a shaft structure (cylindrical portion 17), while an upwardly convex semicircular groove (a circular arc (arc) As the portion 16), the curved surface of the cylindrical portion 17 and the curved surface of the circular arc portion 16 may be fitted to each other to form the fitting portion 18 which holds the pulled-out portion of the roll material. That is, since the contact portion 11 between the flap 6 and the flap receiver 7 comes into surface contact or an approximation thereof, the contact area becomes larger than in the case of the line contact shown in FIG. Can increase the clamping force of the part pulled out from the That is, when cutting the roll material, the circular arc portion 16 of the flap 6 is pressed onto the cylindrical portion 17 functioning as the flap receiver 7 of the roll material body presser 14, and the uncut portion 1b is sandwiched in a wide area, and it is in standby Rewind and omission of the uncut region 1b are more reliably suppressed. Furthermore, since tension is applied to the uncut portion 1b when the roll material is pulled out, the trajectory of the outer peripheral portion of the roll material attempts to draw the shortest route passing through the top of the cylindrical portion 17; The both ends of the circular arc portion 16 are pushed up, the fitting is released, and the gap is widened. For this reason, excessive frictional force is not applied to the uncut region 1b. Then, at the time of cutting, the arc portion 16 is pressed against the cylindrical portion 17 and fitted by receiving an external force at the time of cutting (that is, a force for lifting the tip of the flap), so cutting is performed between the cylindrical portion 17 and the arc portion 16 The remaining portion 1b is sandwiched and fixed.

Still another embodiment is shown in FIGS. The roll material holder concerning this embodiment incorporates the roll material saucer 20 which serves as the uncut part receiving part 10 and the flap receptacle 7. That is, in the roll material holder of this embodiment, in the use position (see FIG. 17), the back side of the outer surface 28 (the part to which the end of the back side of the flap 6 contacts) The roll material receiving tray 20 is used as the portion 10, and in the replacement position (see FIG. 16), the inner surface 27 is used as a receiving tray on which the roll material is placed and supported.

For example, as shown in FIG. 15, the roll material receiving tray 20 causes the outer surface 28 to function as the flap receiver 7 and the uncut receiver 10, while causing the inner surface 27 to function as a temporary placement portion of the roll material 1. 22 and a pair of left and right arm portions 21 supporting the both ends of the tray portion 22 and rotatably supporting the tray portion 22 centering on the roll material supporting shaft 5 of the holder main body 4.

In the case of this embodiment, the saucer portion 22 is an arc shape forming a part of a cylinder, and is formed, for example, in a curved plate (hereinafter referred to as a curved plate) along a curved surface at the maximum diameter of the roll material main body 1a. ing. The tray portion 22 receives the roll material at the exchange position shown in FIG. 16 and exerts a saucer function to assist the roll material replacement operation, and in the use position, it can hold the uncut portion 1b with the flap 6; That is, it is sufficient that the portion (contact portion 11) in contact with the flap 6 as the flap receiver 7 can achieve the degree of adhesion that can hold the pulled-out portion of the roll material. Therefore, although it is preferable that the saucer part 22 is a circular arc surface, it is not restricted in particular to this, For example, polygonal shape may be sufficient.

In addition, the tray portion 22 functions as a temporary placement portion of the roll material at the replacement position, so if the central angle of the arc is too large it will interfere with the insertion of the roll material, and if too narrow, the flap receiver 7 and left uncut at the use position Since the length becomes insufficient when used as the receiving part 10, the range of about 60 ° to 180 °, preferably 70 ° to 150 °, more preferably 80 ° to 130 °, still more preferably 90 ° to 120 For example, in the case of the present embodiment, the arc is set to 120 °, but it is not particularly limited to this.

In the case of the present embodiment, the disk-shaped arm portion 21 has a hole 23 slightly larger than the roll material support shaft 5, and around it an arc-shaped guide groove 24 and a lock for positioning A hole 25 is provided, and a claw 26 projecting from the side member 3 of the holder main body 4 together with the roll material supporting shaft 5 is provided to be engaged with either the guide groove 24 or the locking hole 25. The claw portion 26 is fixed to the arm portion 21 at a predetermined position by engaging with the lock hole 25 and is provided so as not to rotate unless an external force is applied. That is, the roll material receptacle 20 is prevented from rotating by its own weight. The roll material receiving tray 20 fixes the arm portion 21 by providing the claw portion 26 and the locking hole 25 to be engaged at a position where the center of gravity is disposed on the upper side and on the front side of the rotation center axis. ing. Here, in the case of integrally molding the tray portion 22 and the arm portion 21 with synthetic resin, the influence of shifting the gravity center position from the vertical line may not be clear because it is lightweight. In such a case, in order to set the center of gravity closer to the front and ensure rotation of the pan 22, the metal serving as the weight is embedded at a suitable position by insert molding, or a partially thick portion Or a weight may be externally added. For example, a weight may be provided at the front end edge portion of the tray portion 22 or the front end edge portion may be formed thicker than other portions. The guide groove 24 is a groove through which the claw portion 26 passes, and defines a range in which the roll material receiving plate 20 can freely rotate. The guide groove 24 is formed in a wide range so that the roll material receiving tray 20 can be rotated further to the back than the position where the receiving tray portion 22 is suspended by its own weight when suspended by the roll material support shaft 5.

The roll material receiving tray 20 penetrates the roll material support shaft 5 through the hole 23 of the arm portion 21 and is rotatably supported by being hooked on the roll material support shaft 5. Therefore, by setting the center of gravity of the flap receiver 7 on the front side of the vertical line passing through the position at which the edge of the hole 23 contacts the roll material support shaft 5, the distance between the arm portion 21 and the holder main body 4 When the restraint is released, the roll material tray 20 is rotated by its own weight, and the tray portion 22 is supported so as to move downward and be suspended.

Here, in the case of this embodiment, the claw portion 26 and the roll material support shaft 5 are provided with the roll material support shaft 5 and the claw portion 26 at the tip of an L-shaped resin plate, for example. If the spring force is insufficient to ensure locking only with a resin plate, a coil spring etc. is incorporated into the holder main body 4 and the holder main body 4 is incorporated. It may be provided so as to be able to protrude and retract inward from the side member 3 of the above. Further, in the present embodiment, the arm portion 21 is formed in a disk shape having a hole 23 into which the roll material support shaft 5 is inserted at the center, but it does not have to be a disk shape. For example, a fan-shaped plate may be used, and in some cases, a V-shaped or I-shaped rod may be used.

In the present embodiment, the holder body 4 is provided with the locking claw 26 and the arm portion 21 is provided with the locking hole 25 and the guide groove 24 respectively for engagement, but the invention is not limited thereto. A lock mechanism may be provided between the arm portion 21 and the holder body 4 by utilizing the elastic force or structural elastic force of the material itself of the portion 21 and the holder body 4. For example, although not shown, hemispherical projections are formed on the side of the arm portion 21 or the holder main body 4, while the hemispherical holes or through holes are opened on the side of the holder main body 4 or the arm portion 21. The roll material receiving tray 20 can be fixed to the holder main body 4 when fitted. In this case, the arm portion 21 can be rotated by being elastically deformed temporarily at the time of detachment or insertion from the hole or through hole of the hemispherical protrusion, and the arm portion 21 slides on the opposite surface on the holder main body 4 side. To be possible. In this case, the arc-shaped guide groove 24 is not necessary.

Here, the roll material receiving tray 20 is located on the front side of the vertical axis passing through the position where the edge of the hole 23 at the center of the arm portion 21 contacts the roll material support shaft 5 (in FIG. 17, the roll material support shaft The fixed position of the arm portion 21 to the holder main body 4 is set such that the center of gravity is arranged at the position of the first quadrant when the XY coordinate plane passing through the center of 5 is set.

According to the roll holder configured as described above, when replacing the roll material 1, the core of the roll material 1 remaining on the roll material support shaft 5 is lifted and the roll material support shaft 5 is used as the side member 3 of the holder main body 4. If it is removed while being displaced outward in the axial direction so as to be pushed in, at the same time, the locking claw 26 is also disengaged from the locking hole 25 of the roll material receptacle 20 and the lock of the roll material receptacle 20 to the holder body 4 is released. As a result, the roll material receiving tray 20 rotates toward the front side about the roll material support shaft 5 by its own weight, and the tray portion 22 moves to the exchange position (the position shown in FIG. 16). At this time, since the roll material receiving tray 20 is supported so as to be hooked on the roll material support shaft 5, the center of gravity falls on the vertical axis passing through the center of the roll material support shaft 5.

On the other hand, in the case of the present embodiment, the guide groove 24 provided in the arm portion 21 is formed long in order to allow room for the tray portion 22 to rotate further to the back side than the position where it settles under its own weight. For this reason, when attaching the roll material 1 between the roll material support shafts 5, the saucer part 22 can be inclined so as to lower the front side edge to, for example, the lowest position by pushing the saucer part 22 further to the back side. . By this, when the roll material 1 is inserted, the saucer part 22 does not become an obstacle which disturbs.

Therefore, by inserting the roll material 1 between the roll material support shafts 5, the center hollow portion 1c is fitted and rotatably supported. Then, in a state where the left and right roll material support shafts 5 are inserted into the central hollow portion 1c of the roll material body 1a, the roll material body 1a is placed on the pan 22 and temporarily placed. At this time, if the roll material 1 is placed on the receiving plate portion 22 so that the portion pulled out from the roll material main body 1a hangs down on the front side, the roll material receiving plate 20 rotates to the front side (counterclockwise rotation in FIG. 16). By rotating in the direction, the part pulled out from the roll material body 1 a, that is, the uncut part 1 b is rotated while being wound around the outer surface 28 of the tray 22. Then, the uncut portion 1 b is wound up while being sandwiched between the outer surface 28 of the tray 22 and the flap 6. When the upper use position is reached, the lock claw 26 and the lock hole 25 are engaged, and the saucer portion 22 is set in the home position (the state of FIG. 17). As a result, the leading end of the roll material 1 is pulled out to the front side in a state of being sandwiched between the outer surface 28 of the tray 22 and the flap 6, and the front side 28 of the outer surface 28 of the tray 22. It is placed on the part corresponding to the uncut receiver 10.

That is, the tip end of the roll material is placed on the pan 22 (that is, the inner surface 27) with the end of the roll material sufficiently pulled out, and the roll material pan 20 is rotated to the front side (rotation in the counterclockwise direction in FIG. 16). It is possible to put the pulled out portion pulled out from the roll material main body on the uncut receiver 10 while being sandwiched between the flap 6 and the flap receiver 7.

In the case of the roll holder according to the embodiment shown in FIGS. 1 to 14, when replacing (attaching) the roll material 1, the flap 6 is turned and then the tip of the roll material 1 is picked to hold the flap receiver 7 and the holder body It is necessary to pull out from the gap between the four back members 2. In this case, if the gap for pulling out the tip of the roll material is narrow, the work of pulling out the tip portion of the roll material 1 is troublesome, and it will take time to redo when the tip of the roll material 1 falls in the gap. Then, although the above-mentioned clearance must be taken widely, it entails the problem which inevitably causes the enlargement of a holder main part.

On the other hand, in the case of the roll holder according to the present embodiment, the roll material 1 is passed through the roll material support shaft 5 and placed on the saucer portion 22 of the roll material saucer 20 and the tip side is pulled out. The roll material can be set in the holder main body 4 in a state where the uncut portion 1b is pulled out from between the flap receiver 7 and the flap 6 only by rotating the roll material receiving tray 20 to the use position after hanging down. Accordingly, the roll holder can be made compact without impairing the operability at the time of mounting the roll material.

The roll material receiving tray 20 of the present embodiment is provided rotatably around the roll material support shaft 5 with respect to the holder main body by sharing the roll material support shaft 5 to which the roll material 1 is attached as a rotation shaft. The invention is not particularly limited to this, and a dedicated rotation shaft (including a boss or the like) that is separate from the roll material support shaft 5 may be provided to be rotatably supported.

The above-described embodiment is an example of the preferred embodiment of the present invention, but is not limited to this, and various modifications can be made without departing from the scope of the present invention. For example, in the above embodiment, although the roll material is exemplified by the toilet paper having a central cavity, it is not particularly limited to this, and a paper product wound in a roll shape or a polyolefin cut sheet is used Supplies (consumables) For example, a roll film packaging structure (a polyethylene bag is wound into a roll, and can be cut out one by one from a perforation, and is also generally called a roll poly bag), kitchen paper Needless to say, Saran wrap (registered trademark), aluminum wheels, plastic bags, etc. may be used.

In the above-described embodiment, the roll material holder has a structure in which the roll material 1 is inserted from the bottom, the top, or the front side with respect to the holder main body 4 configured by the back member 2 and the left and right side members 3 orthogonal to each other. The example is mainly described, but the invention is not particularly limited thereto. For example, a roll material support shaft (core rod), a flap support shaft, and a flap which vertically stand on a frame member attached to a structure or a wall surface And may be set as a cantilever by inserting the roll material from the side and setting it on the roll material support shaft. For example, although not shown, the above-described roll-like film packaging structure is disposed between a horizontal core bar vertically disposed on the wall surface and a cylindrical holder body surrounding the periphery thereof to store the roll material. It is possible to store it and pull out and cut out the polyethylene bag from the space between the flap and the flap receiver provided at the takeout portion of the cylindrical holder body.

Further, although not shown, the flap receiver 7 also has a passing space expanding mechanism capable of expanding the space between the flap shaft 6a and the like by, for example, pushing down when passing the tip of the roll material. good. In this case, for example, the flap receiver 7 receives and supports the flap receiver 7 with a relatively weak spring, and the flap receiver 7 functions so as to press the flap receiver 7 against the back side of the flap with a spring force unless a pressing force is applied. At the same time, when the roll material 1 is hooked on the tip of the flap 6 and a rotational force is applied to the flap 6, an excessive force does not work because the paper is pinched while the flap receiver 7 is pressed down. When the force pressing down the flap receiver 7 wins relative to each other, it may sink and not exert an excessive force on the tip held between the flap 6 and the flap receiver 7. In the case of the flap receiver 7 with the passing space expanding mechanism, when the tip is pulled out from the roll material and passed between the flap and the flap receiver 7, the flap 6 and the flap receiver are received Since a large space and gap are formed between the two and the seventh, the pulling-out operation of the tip portion, that is, the setting of the roll material can be easily performed.

Further, in the above embodiment, the flap 6 is formed in, for example, a flat plate shape, but it is not particularly limited to this, and at least a flap leading edge portion pressed to cut off the roll material, It is sufficient that the rear end edge portion sandwiching the uncut portion 1b with the flap receiver 7 has a shape that does not damage the pulling-out portion of the roll material and has sufficient rigidity, and the other portion or the whole The structure is not particularly required to have a flat surface or a curved surface. For this reason, for example, a hollow frame such as a lattice can be adopted from the viewpoint of weight reduction and the like.

Moreover, although the flap 6 is made into short length in the above-mentioned embodiment, it does not specifically limit to this. In some cases, as shown in FIG. 8, the flap 6 may be extended in the depth direction close to the back member 2 so that the function as the upper lid of the holder body 4 may be used. In this case, the space above the roll material body 1a can be shielded without increasing the number of parts, and the roll material body 1a can be protected from the intrusion of dust, droplets of water, and the like. In the case of the flap 6, for example, by using a lightweight material such as polyolefin, the operation when passing the part pulled out from the roll material body 1a in the gap between the flap shaft 6a and the flap receiver 7 becomes easy.

Further, as for the relationship between the contact portion 11 of the flap 6 and the flap receiver 7 and the flap shaft (fulcrum point) 6a, securing the parallel directly leads to the improvement of sharpness. Therefore, it is effective to integrate the flap receiver 7 and the bearing of the flap shaft (fulcrum) 6a. For example, as shown in FIG. 11, the flap receiver 7 having the bracket 12 may be attached using the flap shaft 6a. Specifically, the side edges of the side (left uncut receiving portion 10) on the front side of the contact portion (a straight line passing the bending point) 11 in contact with the flap 6 of the flap receiver 7 made of a plate material bent in a mountain shape The bracket 12 is raised to form a hole 13 for allowing the flap shaft 6a to pass therethrough, and the flap receiver 7 may be attached to the holder body 4 using the flap shaft 6a. In this case, a straight line connecting the holes 13 through which the flap shaft 6a passes (flap shaft) and the contact portion 11 are always disposed parallel to each other. Therefore, the space between the flap shaft (fulcrum) 6a and the flap receiver (action point) 7 It is easy to specify the position and secure the parallelism.

In the above embodiment, although the example applied to the toilet paper holder is described by way of example, the invention is not particularly limited thereto, and for example, a polyolefin cut-out product used in roll form, for example It is also possible to target a roll-like film packaging structure (a polyethylene bag is in a roll shape and can be cut one by one from perforations).

Further, in the above embodiment, the flap 6 holds the leading end portion of the roll material by rotation (for example, rotation in the clockwise direction in FIG. 1) so as to press the flap receiver 7 from above by gravity. Although it is not limited to this, it is not particularly limited to this. When the flap shaft 6a is vertically arranged, the bias due to its own weight disappears, but a large frictional force is exerted on the side of the lower roll material. Since it generate | occur | produces, in order to prevent the reverse rotation of roll material, the holding | suppressing force which was made to press on the flap by dead weight becomes unnecessary, and does not prevent implementation. Further, in the lateral installation method of the above embodiment, the holder main body 4 can be rotated so that the flap 6 is always biased toward the flap receiver 7 by its own weight while shifting the flap shaft 6a and the center of gravity of the flap 6 In some cases, the rotational force may be always biased in one direction by applying a spring force or the like.
