Description

  The present invention relates to a marking pen using a fibrous material or a synthetic resin pen tip, and relates to a marking pen including a line marker, a fluorescent pen, a fluorescent marker, a whiteboard marker, a felt pen, a sign pen, and the like.

Conventionally, in this type of invention, as described in, for example, Patent Document 1, a prismatic shaft cylinder (main cylinder 1) in which a writing portion (core tip 5) projects forward, and a rotation around the cylinder. There is a folding-type writing instrument provided with a cap (2) that is supported so as to be movable and covers or opens the writing part by an arc motion.
According to such a folding-type writing instrument, since the cap is used without being separated from the shaft tube, it is possible to prevent the cap from being lost.

However, the conventional technology has a problem in that the rotating cap easily interferes with the writing portion as compared with a structure in which the cap is attached and detached by linear motion due to the structure in which the cap is moved in an arc. For this reason, in particular, when it is intended to construct a marking pen, for example, with a cap that moves in a circular arc as described above, it is necessary to devise since the sealing performance of the cap must be kept high.
Further, in the prior art, since the arc-moving cap is in contact with the front end of the prismatic shaft cylinder, at the time of writing, the front end of the prismatic shaft cylinder is close to the paper surface, and the writing section and writing line May become difficult to view.

The rear end of the writing unit 11 is press-fitted into the ink impregnated body 14 in the main body 12, and the front end is a cylindrical holding portion at the front end of the main body 12. 13, the ink impregnated in the ink impregnated body 14 is guided forward by the capillary force between a large number of fibers (see FIG. 3).
According to the illustrated example, the front end portion of the writing portion 11 is formed in a wedge shape whose thickness is gradually narrowed toward the front, and the linear portion 11a inclined at the protruding end is brought into contact with the writing surface X. (See FIG. 6). The writing part 11 having such a shape may be referred to as a chisel type.
The linear portion 11 a is formed in a linear shape that is inclined with respect to the axial direction of the shaft cylinder and parallel to the flat portion 12 a of the flat body portion 12 of the axial cylinder 11. According to this configuration, the thickest line can be transferred to the maximum when the shaft cylinder 10 is sandwiched and gripped in the thickness direction and writing is performed (see FIG. 6).

The main body 12 has another dimension in which the dimension in one direction (depth direction in FIG. 2) perpendicular to the axial direction of the cylindrical holding part 13 is perpendicular to the one direction and also perpendicular to the axial direction. It is formed in a flat shape smaller than the dimension (left and right direction in FIG. 2).
More specifically, the main body portion 12 has both end surfaces in the thickness direction (the one direction) as flat portions 12a (see FIG. 1) and has inclined surface portions 12b (see FIG. 2) at the front end portions thereof.

(See FIGS. 1 and 4).
The curved surface portion 12e is a portion that comes into contact with the middle finger m when the marking pen 1 is held between the thumb p and the index finger i in the thickness direction as shown in FIG. The grip feeling when supported is improved.

As shown in FIG. 7, the connecting portion 12 f is a convex portion protruding from one flat portion 12 a of the main body portion 12, and the connected portion 12 g is formed on the other flat portion 12 a of the main body portion 12. It is a recess.
Small protrusions 12f1 and 12f1 for locking the connected portion 12g are provided on both side surfaces (left and right end surfaces according to FIG. 7) on the protruding end side of the connecting portion 12f. According to the illustrated example, each small protrusion 12f1 is a single protrusion having a longitudinal rib shape continuous in the axial direction of the axial cylinder. However, as another example, the partial protrusions are spaced apart in the axial direction of the axial cylinder. A plurality of them may be provided.

The ink storage portion 12h is a space in which the front end side communicates with the cylindrical holding portion 13 in the main body portion 12, the rear end side is opened, and the other portion is a wall surface. An ink impregnated body 14 is inserted into the ink storage portion 12h from the rear side, and then the rear end opening of the ink storage portion 12h is closed by the tail plug 15.
The ink impregnated body 14 is obtained by impregnating a cotton pad or felt made of a large number of synthetic fibers with ink.

Further, the cylindrical holding portion 13 is formed in a cylindrical shape that projects forward from the inclined surface portion 12b of the front end of the main body portion 12 along the axial direction of the axial tube and communicates with the inside of the ink storage portion 12h. . According to the illustrated example, the cylindrical holding portion 13 is formed integrally with the main body portion 12. However, the cylindrical holding portion 13 may be configured by connecting a member separate from the main body portion 12 to the main body portion 12. Is possible.
If it demonstrates in detail, this cylindrical holding | maintenance part 13 has the cylindrical small diameter part 13a which made the outer diameter small one time rather than the rear part side in the front-end side. The outer diameter of the small diameter portion 13a is adjusted so that the inner cylinder 22 of the cap 20 is elastically fitted and removed.
The cylindrical holding portion 13 is provided at a position farther from the pivotal support portion 12 c than the central axis of the main body portion 12. That is, the central axis of the cylindrical holding part 13 is arranged away from the central axis of the main body part 12 by an appropriate width w toward the anti-pivot support part (see FIG. 2). The said width | variety is the dimension adjusted suitably so that the fitting / removing property of the cap 20 mentioned later may be favorable.

Further, the position in the axial direction in which the cylindrical holding portion 13 and the inner cylinder of the cap 20 are fitted corresponds to the position of the pivot portion 12c.
The illustrated example will be described more specifically. The position of the front end surface of the cylindrical holding portion 13 (more specifically, the front end surface of the small diameter portion 13a) in the axial tube axis direction (the vertical position in FIG. 2), The cylindrical holding part 13 is arranged so that the position of the central part of the support part 12c in the axial cylinder axis direction substantially coincides. That is, the center part of the pivot part 12c is located on a virtual plane obtained by extending the front end surface of the cylindrical holding part 13 (see FIG. 2).
According to this arrangement, the arc movement of the cap 20 and the fitting / removal of the inner cylinder 22 and the cylindrical holding portion 13 of the cap 20 by the arc movement can be performed smoothly.

  And the writing part 11 is penetrated by the cylindrical holding part 13 of the said structure, and the cylindrical holding part 13 covers the outer peripheral part of the writing part 11 in a cylinder shape, and hold | maintains it.

  Further, the cap 20 is formed in an integral shape including an outer cylinder 21 pivotally supported by the main body 12 and an inner cylinder 22 provided at an interval with respect to the inner surface of the outer cylinder 21, and is unidirectional (see FIG. 3, the inner cylinder 22 is fitted to the cylindrical holding portion 13 from the front side by a circular arc motion in the clockwise direction), and the outer cylinder 21 is brought into contact with the inclined surface portion 12b at the front end of the main body portion 12 so as to move in the opposite direction. The main body portion 12 and the cylindrical holding portion 13 are separated from each other by an arc motion.

The outer cylinder 21 is provided so as to be continuous forward with respect to the outer peripheral surface of the main body 12 in the closed state of the cap 20, and has a bottomed cylindrical shape with the front end as a bottom and the rear end as an opening. It is formed.
The outer cylinder 21 includes a flat portion 21a located at each end in the thickness direction, an inclined opening end portion 21b that contacts the inclined surface portion 12b of the front end of the main body portion 12 on the rear end side, and a pivot of the flat portion 12a. Shaft portion 21c that fits into support portion 12c, projecting piece portion 21d that fits into and out of fitting recess 12d of main body portion 12, and convex curved surface portion 21e that is provided to be continuous with curved surface portion 12e of main body portion 12. And have.

  The flat portion 21 a is a flat surface provided so as to be continuous with the flat portion 12 a of the main body 12. When a plurality of the marking pens 1 are connected and overlapped in the thickness direction as shown in FIG. 7, the flat portions 21a abut the caps 20 to stabilize the connection state.

  The inclined opening end portion 21b is an inclined opening end surface that moves toward the rear of the shaft cylinder as it moves away from the pivot portion 12c in the shaft tube diameter direction. The contact portion between the inclined opening end portion 21b and the inclined surface portion 12b of the main body portion 12 is located on the rear side of the shaft cylinder from the fitting portion between the inner tube 22 of the cap 20 and the tubular holding portion 13. . According to this arrangement, since the cylindrical holding part 13 and the writing part 11 are located on the front side, the writing part 11 and the writing line are easily visible when writing, and the side of the fitting portion is surrounded by the outer cylinder 21. Since it is covered, it also prevents the outflow of ink.

The shaft portion 21c is a shaft-like protrusion provided near the rear end of the end surface in a direction that intersects the thickness direction of the cap 20 and is not in the axial tube axial direction (left-right direction in FIG. 2). The direction is directed to the thickness direction of the cap 20.
If it demonstrates in detail, this axial part 21c has the cylindrical protrusions 21c1 and 21c1 (refer FIG. 5) in the both ends of the axial direction. The two protrusions 21c1 and 21c1 are formed between the pivot portions 12c and 12c so as to elastically push and expand between the pivot portions 12c and 12c on the main body portion 12 side when the cap 20 is fully opened (the state shown in FIG. 2). Inserted (see FIG. 5) and rotatably supported. In addition, the code | symbol 21c11 in FIG. 5 is a chamfering part which makes easy insertion of the axial part 21c between the pivot parts 12c and 12c. The chamfered portion 21c11 is formed in a C chamfered shape or an R chamfered shape at a corner portion of each projection 21c1 near the shaft cylinder 10 in the fully opened state of the cap 20.

The projecting piece 21d is provided on the front end side of the closed cap 20 and at a corner near the shaft 21c, and is formed in a triangular plate shape that is thinner than the other parts of the cap 20.
Protrusions 21d1 and 21d1 are provided on both end faces in the thickness direction of the projecting piece 21d to press-fit the fitting recess 12d of the main body 12. According to the illustrated example, each protrusion 21d1 is a protrusion that protrudes in a convex curved surface. As shown in FIG. 4, when the protrusion 21d is fitted into the fitting recess 12d, The cap 20 is kept in a fully open state by being pressed against the side surface 12d1 and the frictional resistance at that time.
In addition, you may provide the through-hole for attaching a strap or a strap to this flat part 21a as needed.

  The inner cylinder 22 is formed in a substantially bottomed cylindrical shape that protrudes rearward from the bottom surface in the outer cylinder 21 and has an opening end that is a protruding end thereof directed rearward. The opening end portion of the inner cylinder 22 is located on the front side of the opening end portion of the outer cylinder 21 and fits from the front side to the outer peripheral surface of the cylindrical holding portion 13 on the front end side. In this fitted state, the inner cylinder 22 and the cylindrical holding portion 13 are positioned coaxially and in close contact with each other, sealing the space inside. And the part by the side of the front end of the writing part 11 is located in the inner cylinder 22 in this sealed state (refer FIG. 3).

Next, the characteristic effect of the marking pen 1 having the above configuration will be described in detail.
When the cap 20 is moved in an arc so as to be separated from the shaft cylinder 10, the front end of the inner cylinder 22 of the cap 20 is separated from the cylindrical holding portion 13. At this time, the inner cylinder 22 of the cap 20 rotates smoothly without interfering with the writing unit 11 or the like.
Then, the rotated cap 20 fits the projecting piece portion 21d into the fitting recess 12d, and presses the projection 21d1 of the projecting piece portion 21d against the inner side surface 12d1 in the fitting recess 12d, so that the fully open state is achieved. (State shown in FIG. 2).

As shown in FIG. 6, the marking pen 1 in the fully opened state has the flat surface portion 12a sandwiched between the thumb p and the index finger i with the curved surface portion 12e facing forward, and the curved surface portion 12e received by the middle finger m. The writing posture is taken. In this writing posture, the linear portion 11a at the front end of the writing unit 11 is brought into contact with the writing surface X, and a writing line (not shown) is drawn.
At this time, the cap 20 is positioned on the front side (left side in FIG. 6) of the shaft tube 10, and an appropriate distance h is ensured between the front side portion of the main body 12 and the writing surface X. For this reason, the cap 20 does not get in the way at the time of writing, and the writing part 11 and the writing line are not easily seen, and the feeling of use is good.

Further, when closing the cap 20, if the cap 20 is rotated in the opposite direction with respect to the shaft tube 10, the protruding piece 21 d of the cap 20 is detached from the fitting recess 12 d of the main body 12. The cap 20 rotated in the reverse direction fits the inner cylinder 22 into the cylindrical holding part 13 and causes the outer cylinder 21 to abut the inclined surface part 12b on the rear side of the shaft cylinder from the fitting position. Closed state.
In this closed state, the inner peripheral surface on the rear end side of the inner cylinder 22 is fitted to the outer peripheral surface on the front end side of the cylindrical holding portion 13 to maintain the inside in a good sealed state.

The marking pen 1 in the cap closed state can be connected by being stacked in a plurality of thickness directions. If it demonstrates with reference to FIG. 7, the connection part 12f in the upper marking pen 1 will fit in unevenness with respect to the to-be-connected part 12g in the lower marking pen 1. FIG. More specifically, when the connecting portion 12f is inserted into the through hole 12a2 of the main body portion 12, the small protrusion 12f1 of the connecting portion 12f is pressed against the inner edge of the through hole 12a2 and is slightly elastically deformed to be slightly more deformed than the inner edge. It moves to the inside of the part 12 and then elastically restores. Therefore, in a state where the connecting portion 12f is fitted to the connected portion 12g, the small protrusion 12f1 of the connecting portion 12f is locked to the inner edge of the through hole 12a2 so that it does not come out carelessly.
Therefore, a large number of marking pens 1 connected in the thickness direction can be placed on a flat surface, and the storage property and transportability are good.

  In addition, although the main-body part 12, the connection part 12f, the cap 20, and the tail plug 15 are each shape | molded by the synthetic resin material, the extent which enables the attachment or detachment of the cap 20, and the two marking pens 1 and 1 can be connected and detached. It is also possible to form it from other materials, such as a metal material, if it has elasticity.

  Further, in the illustrated example, the rear end portion of the outer cylinder 21 and the main body portion are arranged in order to dispose the position in the axial cylinder axis direction where the outer cylinder 21 and the main body portion 12 abut on the rear side of the position of the pivot portion 12c. Although the 12 front end portion is formed in an inclined surface shape, as another example, the rear end portion of the outer cylinder 21 and the front end portion of the main body portion 12 may be configured to recede stepwise as they move away from the pivotal support portion 12c. .

  In the illustrated example, as a particularly preferable aspect, the shaft tube 10 and the cap 20 have a cross-sectional shape (flat shape) that is long in the width direction substantially orthogonal to the shaft tube axis direction. The cylinder 10 and the cap 20 can also have a circular cross section, a polygonal cross section, and other cross sectional shapes.
