Description

The present invention relates to a thin writing instrument and a set thereof, in which several types of thin writing instruments can be set without falling apart and can be easily selected and used.

Thin writing instruments that are thinner in the width direction are used, and a thin writing instrument case that stores multiple thin writing instruments together is known (for example, see Patent Document 1). It is troublesome to take it out. A writing instrument set in which a plurality of ordinary writing instruments each having a cylindrical barrel are connected together with a ring or the like is known (see, for example, Patent Document 2). The writing instrument set described in Patent Document 2 has a structure in which a penetrating opening is provided in the cap of the writing instrument, and a ring is inserted into the penetrating opening to collect a plurality of writing instruments. However, since the writing instruments are different, they are bulky and inconvenient to carry, and even if writing instruments of different colors are available, it is difficult to select the desired writing instrument. Furthermore, a holder into which the pen nibs and caps of a plurality of writing instruments can be inserted is also known (for example, see Patent Document 3). However, since there is no relationship between the plurality of writing instruments, there is no sense of unity when they are grouped together, and it is difficult to pick out a desired writing instrument from among the plurality of writing instruments.

It protrudes from the tip 4 so that it can be written on. Note that it is also possible to provide an appropriate knock-type feeding mechanism so that the tip of the refill can be moved in and out by a knock operation (not shown).

The tip portion 4 of the thin writing instrument main body 3 is formed solidly, and a portion thereof is exposed from the notch portion formed in the joint 6, and an outer wall portion 8 is continuously provided behind the tip portion 4. In the embodiment shown in FIG. 1, the inner side of the outer wall portion 8 is formed into a hollow shape, and the refill 2 is inserted therethrough. In the embodiment shown in FIG. 3, an inner body 9 having a central hole through which the refill 2 is inserted is made of a transparent plastic material, and the inner body 9 is covered with an outer wall 8, and the inner body 9 is A window 10 is provided along which the refill 2 can be seen through, so that the color of the refill can be visually recognized from the outside. An engagement recess 12 is formed on the outer surface of the tip 4 to removably engage an engagement protrusion 11 formed inside the joint 6 when inserted into the insertion space 5 of the joint 6.

Referring to FIGS. 4 and 5, both sides of the joint 6 are formed as flat parts, and the first flat part 13 on one side is provided with a rotation stopper rib 14, and the second flat part 15 on the other side is provided with a rotation stopper rib 14. A recess 17 is provided that can receive the rotation stopper rib 15 and has a locking edge 16 upright at its end edge. Further, a connection hole 18 is formed to communicate the first plane part 13 and the second plane part 15 so that a plurality of joints 6 can be connected by a connecting means, and a receiving hole 19 for receiving the writing tip of the refill 2 is provided inside. ing.

A combination rim 20 is provided on the periphery of the connection hole 18 so as to protrude from the first plane part 13 side so that the joint 6 can be aligned and combined, and the combination rim 20 is provided on the periphery of the second plane part 15 side. An enlarged hole 21 into which is fitted is formed. In the joints shown in FIGS. 4 and 5, when a plurality of joints are combined, the combination rim 20 simply fits into the enlarged hole 21 and is inscribed therein, but the combination rim 20 can be elastically engaged with the enlarged hole 21. You can also do it. FIG. 6 shows such an embodiment, in which the mating rim 20 is provided with an engaging protrusion 22 around the periphery and a slit in the mating rim 20 so that the mating rim 20 can be elastically deflected inwardly. 23 is formed. A receiving groove 24 is provided on the inner surface of the enlarged hole 21, corresponding to the rim 20 for combination, with which the engagement protrusion 22 engages when the rim 20 for combination is inserted into the enlarged hole 21. With this configuration, when the thin writing instrument 1 is set with the first plane part 13 and the second plane part 15 combined, a plurality of thin writing instruments can be successively connected at each joint 6 portion. According to this embodiment, the engaging protrusion 22 and the receiving groove 24 constitute a connecting means, but any other suitable connecting means may be used.

To explain the relationship between the recess 17 of the joint 6 and the anti-rotation rib 14, as shown in FIG.
