Description

  The present invention relates to a tool used for turning a book or a document page one by one.

  In daily life or in business activities, an act of turning a page of a book or a document occurs frequently. However, it is sometimes difficult to turn a page or the like one by one. Especially in winter, it may be difficult to turn pages and the like due to dryness of the fingertips. In everyday life, although there was some resistance, it was solved by licking the fingertips. However, in business activities, especially during customer service, the fingertips could not be licked. Furthermore, during work using cutting oil or lubricating oil such as metal processing, the finger cannot be licked because the oil adheres to the fingertip.

  Therefore, in general, a sponge soaked with water is prepared, and moisture is appropriately applied from the sponge to a fingertip. However, depending on the amount of water contained in the sponge, a large amount of water may adhere to the fingertips, resulting in a wet state rather than moistening, which may result in uncomfortable and wet documents. It was.

On the other hand, a person who handles books or documents frequently uses a finger sack to give an appropriate frictional resistance to the fingertip, and easily turns a page or the like without damaging the finger frequently. As for this finger sack, various developments have been made on materials or structures from the viewpoint of diversification of purposes of use or durability (see Patent Documents 1 and 2). However, with regard to this finger sack, there are indications that in the summer the sweat of only the finger sacking finger is unpleasant or uncomfortable, or the sensation of the fingertip is dull and unusable, and a rubber tip is attached to the fingertip. Auxiliary tools having a configuration that can be attached are developed (see Patent Documents 3 to 6).
JP 2000-255182 A JP-A-11-157250 Japanese Utility Model Publication No. 8-460 International Publication No. WO2004 / 000572 JP 9-39439 A JP-A-8-310158 Utility Model Registration No. 3109012

  Each of the above prior arts is attached to or stuck to the finger. Certainly, if the emphasis is placed on the sensation of the fingertip, it is possible to turn the paper with a subtle sensation by attaching it to the finger. it can. However, as described above, when it is necessary to turn a document during metal processing or the like, it is difficult to attach or attach to the fingertip because cutting oil or lubricating oil is attached to the fingertip. Yes, even if it is assumed that the finger sucker is used in advance, since the lubricating oil or the like adheres to the surface of the finger suck, after all, the effect of the finger suck cannot be exhibited. It was a thing.

  On the other hand, an instrument having a configuration in which a rubber piece is attached to the head of a pen has been proposed (see Patent Document 7). However, since the above instrument has a configuration in which a rubber piece is only attached to the pen head, it can be turned a small number of times. When turning is required, and when there are frequent occasions to turn the paper, it is necessary to adjust the contact state of the rubber piece with the paper surface. Met. The reason for this is that the pen head is a flat surface or a curved surface that is slightly curved, so the rubber piece to be adhered must be shaped along the surface of the head. In order to turn well, it is necessary to stabilize the state of frictional resistance between the rubber piece and the paper surface. Therefore, in the configuration in which the rubber piece is attached in accordance with the shape of the head of the pen, the friction obtained by the rubber piece This is because it is difficult to bring the resistance into a desired state.

  The present invention has been made in view of the above-mentioned points, and the object of the present invention is to provide an auxiliary tool that can realize a stable paper turning state without being attached or stuck to a fingertip, or It is to provide a writing instrument equipped with the auxiliary tool.

Therefore, the present invention relating to the paper turning aid is made of a flexible plastic, and has a cylindrical body with a bottom, and the body and the constricted part while forming a constricted part at the bottom of the body. A paper turning assisting tool comprising a substantially hemispherical head formed integrally, wherein the constricted part is formed in a tapered shape with a gradually decreasing diameter toward the head on the outer surface of the body part A paper turning aid characterized by comprising a first constricted portion and a second constricted portion formed with a smaller diameter at the boundary portion between the first constricted portion and the head. To do.

According to the above configuration, since the head is substantially hemispherical, by contacting a part of the spherical surface of the head with the surface of the paper to be turned, it is possible to contact at any position of the spherical part. Since the contact area is about the same, the frictional resistance during this contact can be stabilized. In addition, since the head is made of a flexible plastic material, the shape of the head is deformed by the pressing force applied to the head, and the area of the portion in contact with the paper can be increased. the frictional resistance becomes possible to change, it is possible to obtain a desired frictional resistance by adjusting the pressing force by the paper quality to turn by a pressing force applied to.

Moreover, it becomes possible to insert the front-end | tip of a rod-shaped member in the hollow inside of a trunk | drum, having the head which can obtain frictional resistance stably as mentioned above. Therefore, the user can use the stick-shaped member by hand without touching the paper turning aid. Then, by using a writing instrument such as a pencil as the rod-shaped member, even if the writing should be performed while turning the paper, both can be used by changing the writing instrument. Also, when using a pencil as a writing instrument, the paper turning aid will be attached to the rear end of the pencil, and the center of gravity of the pencil will be closer to the rear end. In this posture, the paper turning auxiliary tool is directed downward, and the tip core can be prevented from being damaged.

Furthermore, since the constricted part formed between the trunk part and the head part is configured to have a smaller diameter than the outer diameters of the head part and the trunk part, an external force transverse to the axial direction of the trunk part is applied to the head part. when working, it will be constricted portion is greatly elastically deformed can absorb the external force by the constricted portion. Therefore, when turning the paper, when the head in contact with the paper is moved in the lateral direction, the state where the surface of the head is in contact with the paper can be stabilized even if the angle in the axial direction of the trunk changes. Therefore, a series of operations when turning the paper can be made without difficulty.

  And in each said invention, it is preferable to provide at least 3 protrusion part in the outer peripheral surface of the opening part vicinity of a trunk | drum. According to this aspect, when the body portion is formed of a bottomed cylindrical body, it can be prevented from rolling freely on a plane. Moreover, it is preferable that the surface of a front-end | tip part forms an unevenness | corrugation. According to this aspect, since the frictional resistance with the paper surface is increased, the turning of the paper can be ensured. Furthermore, it is preferable that the trunk portion is fixedly attached to a rod-shaped member having an appropriate length. According to this aspect, since the head portion is configured to protrude from the rod-shaped member, it can be operated while holding the rod-shaped member, and by inserting the rod-shaped member into the pen stand together with other writing tools. It is also possible to preserve the head while protecting it.

  Further, according to the present invention relating to a writing instrument with a paper turning assisting tool, the paper turning assisting tool according to any one of claims 1 to 5 is fixedly attached to the rear end of the writing instrument. The gist is a writing instrument with auxiliary tools.

  According to the above configuration, since the paper turning auxiliary tool is integrated with the writing tool, the writing tool can be used while turning the paper. At this time, since the center of gravity of the entire writing instrument approaches the rear end, the posture of the writing instrument at the time of dropping is directed downward with respect to the paper turning assisting tool, so that the tip of the writing instrument can be prevented from being damaged. In particular, when the writing instrument is a pencil, breakage of the lead can be prevented, so that the life of the pencil can be prolonged.

  According to the present invention relating to the paper turning aid, since it is different from a configuration like a finger sack, it is naturally not attached or stuck to the fingertip. Thereby, firstly, the discomfort at the time of wearing on the finger can be eliminated, and secondly, even when the fingertip is dirty, the paper can be turned without soiling the paper, and thirdly, It can be used even when lubricating oil or the like is attached to the finger.

  In addition, since the shape of the head is substantially hemispherical, the area of the head that comes into contact with the paper surface does not vary greatly, and a stable frictional resistance with the paper surface can be obtained. Therefore, the contact state between the paper surface and the head when turning the paper is stabilized, and the state during the paper turning operation can be stabilized.

  The operation of the head can be performed with the body part, but the body is fitted into a rod-like member or the like, or the rod-like member is inserted into the hollow inside of the body part by inserting the tip of the rod-like member. The head can be protruded from the member or the like, and the paper can be turned with the rod-like member or the like.

  On the other hand, according to the present invention relating to a writing instrument with a paper turning aid, the paper turning aid can realize a stable paper turning state as described above, and simultaneously use the paper turning aid when using the writing instrument. It will be possible.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a first embodiment. FIG. 1A is a perspective view, and FIG. 1B is a front view. As shown in this figure, the paper turning auxiliary tool A of the present embodiment has a substantially hemispherical head 2 integrally formed at the tip of the body 1, and a rod-like member B is formed on the body 1. The insertion portion 11 that can be inserted is formed, and the surface 21 of the head 1 is provided with fine irregularities. By inserting the tip end portion of the rod-like member B into the fitting portion of the trunk portion 1, the paper turning aid A can be attached to the rod-like member B. About the mounting state at this time, since the trunk portion 1 is made of a flexible plastic, the outer diameter Db of the rod-like member B to be inserted is larger than the inner diameter Da of the insertion portion 11. The insertion part 11 is expanded by the insertion of the rod-shaped member B. And since the elastic force arises in the trunk | drum 1 by expansion of this insertion part 11, both will fit firmly. In addition, in order to make it fit in this way, in this embodiment, body part 1 is constituted in bottomed cylinder shape, and head 2 is constituted continuously on the bottom part side of body part 1, If it is the structure which can be made to fit in the rod-shaped member B, the shape of the trunk | drum 2 can be set as a various aspect.

  FIG. 2 shows a second embodiment. (A) is a perspective view, (b) is a front view. As shown in this figure, in the present embodiment, a constricted portion 103 is configured between a bottomed cylindrical body portion 101 and a head portion 102. And the trunk | drum 101 and the head 102 are integrally formed through this constriction part. Since the constricted portion 103 is configured to have a smaller diameter than the outer diameter dimensions of the body portion 101 and the body portion 102, the constricted portion 103 has a generally constricted shape. It will be. In addition, since the shape of the trunk | drum 101 is a bottomed cylindrical shape, the insertion part 111 is formed similarly to 1st embodiment. The head 102 is formed in a columnar shape in the vicinity of the constricted portion 103, but the tip is formed in a substantially hemispherical shape, and the surface 121 of the hemispherical portion is provided with fine irregularities. ing.

  FIG. 3 shows a third embodiment. (A) is a perspective view, (b) is a front view. As shown in this figure, in the present embodiment, the constricted portion 203 to be formed between the body portion 201 and the head portion 202 is formed by tapering the outer surface of the body portion 201. In other words, the outer surface of the body part 201 is tapered so that the outer surface gradually decreases in diameter from the vicinity of one end toward the head part 202 side. The size can be reduced, and the constricted state is formed by the small diameter portion. In this manner, the small diameter portion at the boundary position of the body portion 201 and the head portion 202 has the smallest outer shape, and thus can be bent. In addition, the trunk | drum 201 is formed in the bottomed cylinder shape as a whole, and the insertion part 211 is opening toward one end.

  FIG. 4 shows a modification of the third embodiment described above. (A) is a perspective view, (b) is a right side view. As shown in this figure, in the modification of the third embodiment, the outer diameter dimension in the vicinity of one end of the body 201 is not uniform, that is, in the vicinity of the bottomed cylindrical opening end. In this portion (hereinafter referred to as a cylindrical portion), three projecting portions 241, 242, and 243 are provided. Here, the outer diameter dimension of the cylindrical part of the trunk | drum 201 is comprised to the same extent as the outer diameter dimension of the head 202, and the said projection part 241 is provided by providing the projection parts 241-243 in a cylindrical part. The surface portion of ˜243 is the most protruding state. Thereby, since the projections 241 to 243 exist on the surface of the cylindrical portion, even if the paper turning auxiliary tool A rolls on a plane, the projections 241 to 243 roll. Since it acts to block, it does not roll continuously (see FIG. 4B).

  And when placing on a plane sideways with only this paper turning aid A, the surfaces of both the cylindrical portion of the trunk portion 201 and the cylindrical portion of the head portion 202 abut against the plane, The protrusions 241 to 243 provided on the body part 201 will exhibit a function of preventing rolling, and a bar-like member is inserted into the insertion part 211 of the body part 201, and a paper turning aid is inserted into the bar-like member. When placed on a flat surface with A attached, the paper turning aid A usually has the opening side of the body 202 at the lower position, depending on the weight of the rod-shaped member. It will be inclined. Even in such a state, the protrusions 241 to 243 exhibit a function of preventing rolling. In addition, when the paper turning aid A does not tilt because the weight of the rod-shaped member is light, it is the same as the case where the paper turning aid A is placed on a plane alone. Reference numerals 241 to 243 exhibit a rolling prevention function.

  FIG. 5 shows a modified example different from the above. (A) is a structure provided with both the constricted portion 103 of the second embodiment and the constricted portion 203 of the third embodiment, and (b) is a protrusion in the modified example of (a). In this configuration, 241 to 243 are provided. Moreover, (c) is a figure which shows the use condition of the modification of (a).

  In the modification shown in FIG. 5A, a first constricted portion 203 having a small diameter is formed by providing a taper on the outer surface of the body portion 201, and a boundary portion between the small diameter portion and the head portion 202 is formed. The second constricted portion 103 having a smaller diameter is formed. If configured in this way, the second constricted portion 103 has the smallest diameter, but due to the presence of the first constricted portion 203, the shape is not extremely constricted from the outer diameter of the body portion 201. Thus, a constricted portion that can be easily bent while saving raw materials can be formed.

  Further, in the modified example shown in FIG. 5B, since the projecting portions 241 to 243 are formed on the cylindrical portion of the body portion 201 with respect to the above-described modified example, the paper turning assist is also provided in this modified example. The function of preventing the rolling of the tool A can be exhibited.

  In this way, by forming the entire constriction by the first and second constricted portions 103 and 203, as shown in FIG. 5C, for example, in a state where the paper turning aid A is attached to the rod-shaped member B. Even when the head 202 is strongly pressed against the paper surface P, it is possible to bend from the second constricted portion 103, and appropriate elasticity can be exerted on the head 202 and its tip. And, by exhibiting such elasticity, it is possible to adjust the pressing force required when turning the paper, and even when the paper quality and the like are different, the necessary pressing force is applied to the paper surface P. It will be enough to assist.

  Next, usage forms of the embodiment and the modified example will be described. In any of the embodiments and modifications, since the portion that contacts the paper surface P is a substantially hemispherical portion formed at the tip of the heads 2, 102, 202, all are in the same usage form. The modification shown in a) will be described as a representative.

  As shown in FIG. 6, when using the paper turning auxiliary tool A, the hemispherical portion of the auxiliary tool A is brought into contact with the surface of the uppermost paper material P1 among the paper materials Pa to be laminated (FIG. 6 ( In this state, the entire auxiliary tool A is moved (see FIG. 6B). Here, as a case where it is necessary to use the paper turning auxiliary tool A, a plurality of paper materials are laminated as in the case of sequentially turning pages such as books or finding a necessary document from a bundle of documents. This is a case where only one of the uppermost layers is turned from the state.

  Therefore, by pressing the paper turning auxiliary tool A against the surface of the paper material P1 with an appropriate pressing force, the hemispherical portion comes into contact with the surface of the paper material P1 and has an appropriate frictional resistance against the paper material P1. By giving, it can be separated from the paper material P2 of the next layer. At this time, when the frictional resistance generated between the hemispherical portion of the paper turning auxiliary tool A and the uppermost paper material P1 is larger than the frictional resistance generated between the paper material P1 and the next paper material P2. The uppermost paper material P1 is turned along with the movement of the auxiliary tool A. When the auxiliary tool A is strongly pressed against the surface of the paper material P1, the uppermost paper material P1 is pressed by the pressure at that time. Since the frictional resistance between P1 and the paper material P2 of the next layer becomes large, the paper material P2 of the next layer is turned over so as to be attracted to the paper material P1 of the uppermost layer, so an appropriate pressing force is given. It is important. Note that the amount of such pressing force varies slightly depending on the paper quality and printing state, but a sufficient procedure can be obtained by using it several times. Then, by moving the paper turning auxiliary tool A while applying such an appropriate pressing force, the uppermost paper surface P1 moves the portion that contacts the hemispherical portion, and the paper surface P1 turns in a wave shape. It will go up. Thus, by holding the corrugated portion with the hand or finger on the side where the auxiliary tool A is not operated, only one of the uppermost paper material P1 can be completely turned.

  Since the usage method of the embodiment of the present invention is as described above, if the hemispherical portion formed at the tip of the head 2, 102, 202 of the paper turning auxiliary tool A can be brought into contact with the paper surface, the rod-shaped member B It can be used even if it is not installed. That is, by sandwiching the body portions 1, 101, 201 of the auxiliary tool A with fingers, the heads 2, 102, 202 can be brought into contact with the paper surface, and the auxiliary tool A can be moved. It is. Even in this case, the uppermost paper material P1 can be turned up in a wave shape.

  As described above, since the method for turning the paper material is the same regardless of the mode of use, it may be selected according to the user's convenience. If the paper turning auxiliary tool A is attached to the rod-shaped member B, the rod-shaped member B can be stored together with the writing tool by inserting the rod-shaped member B into a pen stand or the like. When the auxiliary tool A is used independently, it can be stored together with an eraser or the like. Furthermore, by attaching the rod-shaped member B to the rear end of a writing instrument such as a pencil, it is possible to use both if the pencil is changed only when necessary when using the pencil.

  Embodiments of the present invention are as described above, but various modes can be taken without departing from the spirit of the present invention. For example, as for the cross-sectional shapes of the insertion holes 11, 111, and 211 provided in the body portions 1, 101, and 201, only the circular shape is shown in any of the above-described aspects, but as shown in FIG. The cross-sectional shape of the insertion hole 311 may be a hexagon. In the case of such a configuration, for example, when the auxiliary tool A is attached to the rear end of a hexagonal cross-sectional pencil, the auxiliary tool A can be fitted to the tip of the pencil. In addition, regarding the outer shape of the body portions 1, 101, and 201 of the auxiliary tool A, only the one having a circular cross section is shown in the above embodiment, but it is possible to make this a polygonal shape. Therefore, for example, as shown in FIG. 7B, the outer shape of the body 301 can be a hexagonal cross section. In the case of such a configuration, even when the auxiliary tool A is placed sideways on a flat plane such as a desk, it does not easily roll on the plane. This can be evaluated as a modification of the embodiment shown in FIG.

(A) is a perspective view of 1st embodiment, (b) is a front view. (A) is a perspective view of 2nd embodiment, (b) is a front view. (A) is a perspective view of 3rd embodiment, (b) is a front view. It is a figure which shows the modification of 3rd embodiment. (A) And (b) is a figure which shows another modification, (c) is a figure which shows the use condition. It is a figure which shows the usage condition of this invention. It is a perspective view which shows other embodiment.
