Description

  The present invention relates to a writing instrument such as a so-called line marker in which a pen tip portion has directionality.

Conventionally, in a writing instrument comprising a writing instrument main body having a directional pen tip on the tip side and a cap that is detachably attached to the writing instrument main body so as to cover the pen tip, the writing instrument main body should be gripped A configuration is known in which when a concave portion indicating a location is formed and a fingertip is positioned in the concave portion, the orientation of the pen tip portion matches a writing surface such as a paper sheet (for example, Patent Document 1). . In addition, a concavity in which the thumb, the index finger, and the middle finger are in contact with each other at the time of writing is considered on the tip side (position close to the pen tip) of the writing unit body (see, for example, Patent Document 2).
Japanese Utility Model Publication No. 50-84114 (pages 1 and 2, FIGS. 2 and 3) Japanese Patent Laid-Open No. 11-34570 (pages 1 and 2, FIGS. 1 and 3)

  However, the conventional one is configured so that the orientation of the pen tip portion matches the writing surface by positioning the finger in the concave portion formed in the writing instrument body, but the cap is covered with the pen tip portion. In the state where it is attached to the writing instrument body, it is impossible to grasp the position of the concave part or the direction of the pen tip part, so after removing the cap from the writing instrument main body once, confirm the position of the concave part or the direction of the pen tip part, Must be re-gripped. As described above, the conventional product needs to check the position of the recess or the direction of the pen tip after removing the cap, so the writing operation cannot be performed smoothly and smoothly, and it is not easy to use. .

  The present invention has been made paying attention to such a problem, and a main purpose thereof is to easily recognize the direction of the pen tip even when the cap is attached, and to smoothly apply the pen tip. An object of the present invention is to provide a writing instrument that can quickly and easily perform a writing operation in accordance with the direction of the writing surface.

  That is, the binding tool of the present invention comprises a writing instrument body provided with a pen tip on the tip side, and a cap that is detachably attached to the writing instrument body so as to cover the pen tip part, The pen tip portion has directionality, and is a writing instrument configured to be writable by matching the direction of the pen tip portion to a writing surface such as a paper sheet, and the writing tip body has an orientation of the pen tip portion. A finger-holding part to which an index finger is attached so as to match the writing surface, and a guide that suggests the orientation of the pen-tip part in a state in which the cap is attached and can guide the fingertip of the index finger to the finger-holding part It forms the part.

  If this is the case, the direction of the pen tip can be easily recognized with the guide portion as a clue even when the cap is attached. There is no need to check the orientation. Moreover, since the guide part is set so that the fingertip is guided to the finger hook part, the direction of the pen point part can be smoothly adjusted to the writing surface, and the writing work can be performed quickly and easily. .

  As a specific embodiment, the guide part is a recessed part that is recessed from a peripheral part, and the finger hook part is a recessed part that is further recessed from the recessed part and into which the fingertip can be fitted. .

  Further, if the guide part and the finger hook part are continuously formed along the axial direction of the writing instrument body, the finger tip can be moved as it is along the guide part to reach the finger hook part as it is. It is possible and suitable.

  In order to ensure that the direction of the fingertip and the direction of the pen tip portion is surely matched, the guide portion and the finger hook portion may be formed only at one place on the writing instrument body.

  The writing instrument main body comprises a substantially cylindrical front tube portion integrally having a pen tip portion on the front end side, and a substantially cylindrical rear tube portion separable from the front tube portion, and the guide portion And if the said finger hook part is formed in the said front cylinder part, while producing the said effect, it will interfere with the simplicity of the operation | work which isolate | separates a front cylinder part and a rear cylinder part, and replaces | exchanges an ink cartridge. Never come. Moreover, the guide part and the finger hook part also function as a pressing part (finger hook part) when separating the front cylinder part and the rear cylinder part, and the replacement work of the batting can be performed more easily.

  In this case, in order to grasp the guide part more easily and reliably, it is preferable that the guide part has a substantially flat shape extending along the axial direction of the writing instrument body.

  Specifically, the pen point portion is for a line marker such as a fluorescent marker, and the tip surface thereof is inclined at a predetermined angle with respect to the axial direction of the writing instrument body.

  As described above, according to the writing instrument of the present invention, the orientation of the pen tip part is easy with the guide part formed on the writing instrument body as a mark even in a state where the cap is attached to the writing instrument body so as to cover the pen tip part. Can be recognized and the fingertip can be guided to the finger rest using a guide portion that can guide the fingertip. Can be matched to the surface. In this way, the writing operation can be performed quickly and easily without going through the troublesome task of confirming the orientation of the pen tip after removing the cap from the writing instrument body and re-gripping.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1 and the like, the writing instrument 1 according to the present invention is detachably attached to the writing instrument body 2 having a pen tip portion 2p on the tip side and the pen tip portion 2p so as to cover the pen tip portion 2p. The cap 3 is provided. In the following description, “tip”, which is a term indicating the position or direction, refers to the side where the pen tip portion 2p is provided for the writing instrument body 2, and the side covering the pen tip portion 2p for the cap 3. The “group” refers to the opposite side of the writing instrument body 2 from the side where the pen tip portion 2p is provided, and the cap 3 refers to the side covering the pen tip portion 2p. Therefore, in a state where the cap 3 is mounted on the writing instrument body 2 so as to cover the pen tip portion 2p, the “tip” of the cap 3 and the writing instrument body 2 and the “base” of the cap 3 and the writing instrument body 2 are in the same direction. Will point.

  The writing instrument body 2 is, for example, an injection-molded product mainly made of synthetic resin, and is shown in FIGS. 2 to 5 ((a) in each of FIGS. 3 to 5 is a plan view, and (b) is a side view). Thus, it is comprised by the substantially cylindrical front cylinder part 2a which has the pen tip part 2p integrally in the front end side, and the substantially cylindrical rear cylinder part 2b separable from this front cylinder part 2a.

  The pen tip portion 2p is formed in a so-called knife-cut shape in which the tip end surface is inclined at a predetermined angle with respect to the axial direction of the writing instrument body 2 (the axial direction means the longitudinal direction and will be used in the following description). In addition, a wide line can be drawn at a predetermined position on the writing surface by aligning the direction of the pen tip portion 2p so that the substantially entire area of the front end surface is in contact with the writing surface such as a paper sheet. For line markers. In this way, the pen tip portion 2p has directionality, and is configured to be writable by matching the direction of the pen tip portion 2p with the writing surface. For convenience of explanation, a portion forming an acute angle in the pen tip portion 2p is referred to as a top portion 2pa (see FIG. 3B). The nib portion 2p is connected to an ink storage body (not shown) consisting of a cotton pad impregnated with ink inside the writing instrument body 2 and a cylindrical body in which the cotton pad is housed. The structure is supplied. Accordingly, since the ink is volatilized when the pen tip portion 2p is exposed, the volatilization of the ink is prevented by covering the pen tip portion 2p with the cap 3 when not in use.

  Thus, the orientation of the pen tip portion 2p when the cap 3 is attached to the front tube portion 2a with the recessed portion 21 serving as a finger hook portion to which the index finger is attached so that the orientation of the pen tip portion 2p matches the writing surface. And the concave portion 22 is formed as a guide portion capable of guiding the fingertip to the concave portion 21. The concave portion 22 is formed in a predetermined region along the axial direction of the front cylindrical portion 2a. Specifically, the concave portion 22 extends from a region near the base end portion of the front cylindrical portion 2a to a substantially central portion of the front cylindrical portion 2a. The region is formed in a substantially flat shape, and the region is recessed from other regions. In this embodiment, this recessed part 22 is formed only in one place on the circumference of the front cylinder part 2a. On the other hand, the recessed portion 21 is formed so as to be continuous with the recessed portion 22 along the axial direction of the front cylinder portion 2a. Specifically, the recessed portion 21 is further recessed from the recessed portion 22 and slides along the recessed portion 22. In order to fit the fingertip, the center portion has a substantially arc shape in a side view with the deepest portion at the center. The top part 2pa of the pen tip part 2p is set so as to be positioned on a virtual straight line along the axial direction of the location where the continuous concave part 22 and the concave part 21 are formed. By adopting such a configuration, when the fingertip of the index finger is positioned in the recessed portion 21, the orientation of the pen tip portion 2p matches the writing surface, and the orientation of the pen tip portion 2p can be easily adjusted to the writing surface. It becomes possible to match. Note that a screwing portion (not shown) for screwing into the rear cylinder portion 2b is formed at the base end portion of the front cylinder portion 2a.

  As shown in FIG. 2 and the like, the rear cylinder part 2b is longer than the front cylinder part 2a, and has a shape in which a substantially central portion in the axial direction is slightly reduced in diameter from other regions and is constricted. The front end portion has a screwing portion (not shown) into which the front tube portion 2a is screwed. Further, a cap 3 that is removed from the pen tip portion 2p side at the time of writing can be attached to the proximal end portion side of the rear cylinder portion 2b. Furthermore, the protrusion 23 which protruded from the other part is provided in one place on the circumference in the vicinity of the base end part of the rear cylinder part 2b to prevent rolling when the writing instrument 1 is placed on a plane such as a desk. Yes. The protrusion 23 prevents rolling, and when the cap 3 is inserted into the proximal end portion of the rear cylinder portion 2b, the opening end (base end) of the cap 3 comes into contact with the cap 3 so that the cap 3 can be inserted further. It also serves as a positioning means for regulating and positioning an appropriate mounting position of the cap 3 (see FIG. 5).

  The front cylinder part 2a and the rear cylinder part 2b which comprise the structure mentioned above are attached so that attachment or detachment is possible via the screwing part which is provided in each. By adopting such a configuration, an ink cartridge (not shown) provided in the writing instrument body 2 can be replaced. In addition, when the ink cartridge is replaced, the concave portion 22 or the concave portion 21 of the front cylindrical portion 2a functions as a pressing portion (finger holding portion) when twisting the rear cylindrical portion 2b, which will be described later, in the screwing release direction. Simplification.

  The cap 3 is formed, for example, by injection molding of synthetic resin. As shown in FIGS. 2 to 5 and the like, the cap body 31 having a substantially cylindrical shape with a base end side opened, and the cap body 31 are formed. The clip 32 is integrally provided with a clip 32 that is provided in a region extending from the vicinity of the distal end portion to the proximal end portion on the outer surface side, and can be held in a state of being hooked on the edge of a chest pocket of a piece of paper or clothes. The cap body 31 is set to have a smaller dimension (longitudinal dimension) in the axial direction than the front cylinder portion 2a, and the cap 3 can be attached to and detached from the writing instrument body 2 so as to cover the pen tip portion 2p when the writing instrument 1 is not used. In the state where it is fitted in, a part of the recess 22 formed in the front tube portion 2a is exposed (see FIG. 4). Note that a pressing portion 32 a that protrudes toward the cap body 31 is formed on the inner surface of the rear end portion of the clip 32.

  Next, the usage method of the writing instrument 1 which has such a structure is demonstrated with reference to FIG. First, with the cap 3 attached to the writing instrument body 2 so as to cover the pen tip portion 2p, an index finger is attached to the partially exposed recess 22 (FIG. 1A). Omitted). Then, when the cap 3 is removed from the writing instrument main body 2, the entire concave portion 22 is exposed, and the index finger is slid along the concave portion 22 to the distal end side of the writing instrument main body 2. As a result, the belly of the index finger fits into and fits into the recessed portion 21 formed continuously with the recessed portion 22 ((b) in the figure). If the writing posture is entered as it is from this state, the direction of the pen tip portion 2p does not need to be adjusted one by one, but the entire entire area of the tip end surface of the pen tip portion 2p naturally touches the writing surface, and the predetermined area of the writing surface is widened. Can be drawn (see FIG. 2). The cap 3 once removed may be attached to the proximal end side of the writing instrument body 2.

  As described above, the writing instrument 1 according to the present embodiment has the pen tip in a state where the concave part 21 to which the index finger is attached and the cap 3 are attached to the writing instrument body 2 so that the orientation of the pen tip part 2p matches the writing surface. Since the concave portion 22 that indicates the direction of the portion 2p and guides the fingertip to the concave portion 21 is formed, the direction of the pen tip portion 2p can be easily recognized using the concave portion 21 as a mark even when the cap 3 is attached. There is no need to confirm the orientation of the pen tip portion 2p after removing the cap 3 as in the prior art. In addition, since the concave portion 22 functions as a guide portion for guiding the fingertip to the concave portion 21, the direction of the pen tip portion 2p is changed to the writing surface by smoothly guiding the fingertip to the concave portion 21 using the concave portion 22. The writing work can be performed easily and easily.

  Moreover, since the recessed part 22 and the recessed part 21 are continuously formed along the axial center direction of the writing instrument main body 2, if the fingertip is shifted along the recessed part 22, it can reach the recessed part 21 as it is. The index finger attached at the time of writing can be fitted to the recess 21 in a natural state.

  In addition, since the concave portion 22 and the concave portion 21 are formed only at one location on the circumference of the writing instrument body 2, the direction of the fingertip and the pen tip portion 2p can be reliably matched, and it is easy to use. It will be.

  The writing instrument body 2 includes a substantially cylindrical front tube portion 2a integrally having a pen tip portion 2p on the front end side, and a substantially cylindrical rear tube portion 2b separable from the front tube portion 2a. In addition, since the recessed portion 21 is formed in the front cylinder portion 2a, there is no loss in the convenience of replacing the ink cartridge by separating the front cylinder portion 2a and the rear cylinder portion 2b while achieving the above effects. . In addition, when the ink cartridge is replaced, when the screwing between the front cylinder part 2a and the rear cylinder part 2b is released and the writing instrument body 2 is separated, the concave part 22 or the concave part 21 twists the front cylinder part 2a in the screwing release direction. Since it functions as a pressing portion (finger holding portion) at the time, the replacement work of the ink cartridge can be easily performed.

  In particular, in the present embodiment in which the front cylindrical portion 2a is substantially cylindrical, the concave portion 22 is a substantially flat shape extending along the axial direction of the writing instrument body 2, so that the concave portion 22 can be grasped more easily and reliably. can do.

  The present invention is not limited to the embodiment described in detail above.

  For example, in order to further improve the ease of holding and writing, in addition to the recessed portion into which the index finger is fitted during writing, a recessed portion into which the thumb can be fitted or a recessed portion into which the middle finger can be fitted may be formed.

  Moreover, the guide part should just suggest the direction of a pen tip part, and can guide a fingertip to a finger hook part, and is not restricted to a flat recessed part, for example, unevenness, a wave shape, or a finger hook Even those having various shapes such as an inclined surface formed by gradually increasing the depth of the depression toward the portion can be suitably used. Similarly, various concave shapes may be employed.

  In addition, the relationship between the guide unit and the finger-holding unit may be a relationship that naturally reaches the finger-holding unit when the finger is moved along the guide unit. It does not need to be formed continuously.

  If the ink cartridge is a so-called disposable writing instrument that cannot be replaced, the writing instrument body need not be composed of a front cylinder part and a rear cylinder part, but may be composed of a single member. In that case, the writing instrument body may be in the form of a generally square pipe. Further, not only the distal end side of the writing instrument body but also the proximal end side may be provided with a pen tip portion. In this case, a finger hook portion and a guide portion corresponding to the pen tip portion provided on the proximal end side may be formed on the writing instrument body.

  The pen tip portion may be of any type as long as it has directionality, such as a fountain pen, in addition to a line marker such as a fluorescent marker.

  Moreover, if the writing instrument main body and the cap are formed using a translucent material, the direction of the pen tip portion can be grasped more clearly.

  The writing surface means an object that can be written using a writing instrument, and is a concept that includes not only paper such as paper but also a whiteboard and a blackboard.

  In addition, the specific configuration of each part is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
