[0010]

Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same members and the same parts are denoted by the same reference numerals. As shown in FIGS. 1 to 6, the slide-type composite writing instrument 1 having the clip according to the present embodiment has a shaft cylinder structure in which a rear shaft 3 is screwed to a rear end of a front shaft 2. The ball-point pen refill 5 and the ball-point pen refill 7 containing ink (not shown) different in color from the ball-point pen refill 5 are stored by being biased rearward by the resilient members 13 and 14 abutting on the spring receiving portion 19. is there. The rear shaft 3 is formed with a sliding portion 16 that extends in the axial direction and that is open outward, which is defined in a radial direction. The sliding portion 16 is provided with the ball-point pen refills 5 and 7.
Sliders 11, 12 of the same color as the ink color connected to the rear ends of the ink storage cylinders 9, 10 are slidably disposed. The ball-point pen refills 5 and 7 have an ink (not shown) provided with shear thinning in the ink storage cylinders 9 and 10 and a grease-shaped rear end of the ink that moves following the ink as the ink is consumed. Of the ink follower (not shown). In addition, the writing tips 6, 8 of the ballpoint pen refill
Although not shown, the ball-point pen structure has a coil spring for always pressing the ball rotatably held at the tip against the inner wall surface of the tip.

The sliding members 11 and 12 have raised portions 11 a and 12
The raised portions 11a and 12a are held so as to protrude from the outer peripheral surface of the rear shaft 3 from the sliding portion 16 opened outward. The protruding portion 12a is advanced in the direction of the shaft cylinder tip opening 2a (the direction of arrow G in FIG. 5), so that the locking portion 12b formed on the sliding body 12 is locked on the stopping portion 3a formed inside the rear shaft 3. Then, the writing tip 8 of the ballpoint pen refill 7 can be selectively projected from the tip opening 2a of the front shaft 2. A grip member 18 is attached to a grip portion of the front shaft 2, and a clip 15 is formed integrally with the rear shaft 3 on the outer periphery of the rear shaft 3.

A slide portion 17 that opens outward is formed at a position facing the clip 15 of the rear shaft 3, and a protrusion 4 a formed on the slide member 4 is formed on the slide portion 17. The slide member 4 is slidably provided so as to protrude outward from the rear shaft 3. At this time, in consideration of a case where a thin member (not shown) is clamped by the clip 15, the wall surface 1 of the clip member 15 facing the shaft cylinder is taken into consideration.
It is preferable to set the amount of protrusion of the protrusion 4a so as to minimize the gap between 5a and the tip of the protrusion 4a of the slide member. When the clip 15 comes into contact with the projection 4a, the sliding of the slide member 4 is not smooth. Therefore, as shown in FIG. 6, a concave groove 15b is formed on the wall surface 15a of the clip 15 facing the shaft cylinder. By making the protrusion 4a of the slide member 4 sneak into the concave groove 15b of the clip so as not to contact the clip member 15, even if a thin member (not shown) is sandwiched between the clips 15, This is preferable because it comes into contact with the protrusion 4a of the slide member. Further, as shown in FIG. 6, the engagement protrusion 1 formed on the slide portion 17 is attached to the slide member 4.
By forming the engaging groove 4d for engaging the engaging member 7a and slidably engaging the engaging protrusion 17a and the engaging groove 4d, it is possible to prevent rattling of the slide member 4,
The sliding of the slide member 4 can be made smoother.

The sliding member 4 is formed on the sliding body 12 by advancing one protruding portion 12a in the direction of the opening 2a of the barrel cylinder (in the direction of arrow G in FIG. 5), which is an operation of projecting the writing tip 8. Stop portion 3 in which locking portion 12b is formed inside rear shaft 3
a, the wall surface 12d of the release protrusion 12c of the sliding member 12 is in contact with the wall surface 4d of the release protrusion 4b of the slide member 4.
By contacting the sliding member 12 and moving the sliding body 12 forward, the sliding body 12 advances from the rear end of the barrel to the tip of the barrel. Further, by moving the protruding portion 11a of the other sliding body 11 forward in the direction of the opening 2a at the tip end of the barrel, the other releasing projection 11c presses the one releasing projection 12c and locks on the stopper 3a. By releasing the locking portion 12b, the sliding body 12 that has been advanced is urged by the spring 14 toward the rear shaft rear end 3b and returns to the original position. At this time, the protruding writing tip 8 also sinks through the shaft cylinder tip opening 2a. However, the slide member 4 remains in the advanced state without interlocking with the retreat of the slide body 12 in the direction of the rear end 3b of the barrel.

If the clip 15 is clamped by, for example, a pocket cloth (not shown) in a state where the writing tip 8 is in a protruding state, the pocket cloth comes into contact with the projection 4a of the slide member 4, and furthermore, When the fabric of the pocket enters the rear end 3b of the barrel, the slide member 4 also moves backward.
By this retreat, the release projection 4b of the slide member 4
The release protrusion 4b of the slide member 4 is brought into contact with the release protrusion 12c of the slide body 12 and further retracted, whereby the release protrusion 4b of the slide member 4 is moved.
2 is released by pressing the release projection 12c of the sliding body 12 to the outer side of the barrel, and the locking portion 12 of the sliding body 12 locked to the stopper 3a.
Release b. When the locking portion 12 is released, the sliding body 12 that has been advanced is urged by the spring 14 toward the rear end 3b of the rear shaft to return to the original position, and the writing tip 8 that has protruded.
Is also immersed through the shaft tube tip opening 2a. That is, with the writing tip 8 protruding, the clip 1 is attached to the fabric of the pocket.
When the clip 5 is pinched, the writing tip 8 is immersed, and the safety mechanism does not stain the fabric of the pocket.

The sliding member 4 of the present invention comprises a sliding member 11,
12 is set so as to interlock only with the movement in the advanced direction (the direction of arrow G in FIG. 5) and not with the movement in the retreating direction of the sliding body (the direction of arrow F in FIG. 2). It is important to set the slide member 4 to retreat by the held member. That is, in the slide-type composite writing instrument 1 of the present invention, the operation of the writing tip portions 6 and 8 does not depend on the clip member 15.
Even if the clip member 15 is in a damaged state, writing is possible.

In this embodiment, the front shaft 2 and the rear shaft 3 are screwed together to form a shaft cylinder, and the rear shaft 3 is formed with the sliding portion 16, but the shaft cylinder is integrally formed. A sliding portion may be formed at the rear end of the barrel, or a sliding case (not shown) may be provided at the rear end of the barrel to partition the sliding portion in the radial direction. .

Further, in this embodiment, a ballpoint pen refill is used as a writing body, but the present invention is not limited to this. Further, the ballpoint pen tip structure also has a structure in which the ball is directly pressed by the tip of the coil spring. However, a pressing element (not shown) may be interposed between the ball and the coil spring, or the coil spring may be used. The structure which is not provided may be sufficient. The structure for connecting the sliding body to the writing body is not particularly limited, and a tail plug is inserted directly into the rear end of the ink storage cylinder or at the rear end of the ink storage cylinder. , 12 can be used.

The slide-type composite writing instrument 1 having a clip according to the present embodiment uses a slide-type multicolor ball-point pen containing two ball-point pen refills of different colors. Alternatively, a plurality of cursives such as three mechanical pencils can be appropriately selected and used. The ink contained in the ballpoint pen refill is not particularly limited, but a ballpoint pen containing a low-viscosity aqueous ink, an oily ink having a viscosity of 3000 mPa · s or less at 25 ° C., or an ink provided with a shear thinning property. In the case of a refill, the ink is particularly effective because the ink permeates into the fabric of the pocket and easily fouls.

[0019]

As described above, according to the present invention, even if the writing tip of the cursive body is attached to clothing such as a pocket with the writing tip protruding, the clothing is not stained and the clip is temporarily damaged. Even in such a case, a slide-type composite writing instrument having a clip, which allows the writing tip to move in and out, could be provided.
