Abstract

PURPOSE:To reduce the overall length of a writing instrument and permit its center stick to be smoothly propelled or retracted by a method wherein a refill is fitted into the writing instrument, a propelling base plate having a spiral groove formed on its outer periphery is provided and a rod-shaped object support is movably engaged with the spiral groove. CONSTITUTION:When a cap 4 is rotated relative to an outer cylinder 1, its rotary force is transmitted through an axially extending groove 4a of the cap 4 to a pawl part 9c of an eraser support 9. Since a propelling base plate 8 is prevented from rotating by a projecting piece 8a in engagement with the axially extending groove 1a of the outer cylinder 1, when a projection 9a of the eraser 5 is rotated relative to a spiral groove 7, the eraser 5, by its propelling action, moves in the axial direction shown by the arrow of the outer cylinder 1 while being steered by the pawl 9c of the eraser 5 and an axially extending groove 4c so as to be propelled or retracted through the rear end 4a of the cap 4. When the cap 4 is knocked, its knocking force is transmitted from the cap 4 through the propelling base part 8 to a center stick pipe 3. Since the propelling base plate 8 is slidably movable axially relative to the axially extending groove 1a of the outer cylinder 1, the cap 4, the propelling base part 8, the eraser support 9, the eraser 5 and the center stick pipe 3 are all moved forward to permit the center stick to be propelled from the writing instrument.

However, in conventional writing instruments with an eraser of this kind, the inside of the rear end of the outer cylinder is closed with a screw member, so a writing part is provided at the tip and a core pipe (mechanical pencil) that is inserted into the outer cylinder. The refill of the ink pipe (in the case of a ballpoint pen) or ink pipe (in the case of a ballpoint pen) becomes very short.
There was a problem in that if you tried to make the refill longer, the entire writing instrument would become longer than necessary. This invention was made to solve the above problems, and although the refill can be made sufficiently long, the entire writing instrument can be made sufficiently short.
Another object of the present invention is to provide a writing instrument with a stick-like object feeding device that allows stick-like objects to be taken in and out smoothly.

An embodiment of the present invention will be described below with reference to the drawings. First, an outline of a mechanical pencil according to a first embodiment of the present invention will be explained with reference to FIG. A tip 2 is coaxially attached to the tip of the outer cylinder 1 and is removably attached, and a core pipe (refill) is installed inside the outer cylinder 1.
3 is slidably arranged. At the tip of this core pipe 3, there is a known core delivery mechanism A.
However, a cap 4 is coaxially and removably attached to the rear end. An eraser (rod-shaped object) 5 is disposed coaxially within the cap 4, and when the cap 4 is rotated with respect to the outer cylinder 1, the eraser 5 is moved in the axial direction from the rear end 4a of the cap 4. It is configured to be automatically put in and taken out in the direction of the arrow. Next, an eraser (stick-shaped object) according to the first embodiment of the present invention
The feeding mechanism 6 will be explained. The eraser feeding mechanism 6 is removably fitted to the rear end of the core pipe 3, and is engaged with a feeding base 8 in which a spiral groove 7 is formed and the spiral groove 7 of this feeding base 8, and slides in the axial direction. It consists of an eraser holder (stick-shaped object holder) 9. As shown in FIG. 2(a), the feeding base 8 has a spiral groove 7 formed on its outer periphery. An annular groove 7 having a shallower depth than the helical groove 7 is provided at both ends of the helical groove 7.
a is formed, so that even if the cap 4 is rotated excessively, the protrusion 9a, which will be described later, will simply rotate in this annular groove 7a, and the eraser 5 will not come off from the helical groove 7.
Since the depth of the annular groove 7a is partially shallower than that of the spiral groove 7, the user feels an unnatural rotation and feels like stopping the rotation. Also, this spiral groove 7. As shown in FIG. 2(b), the annular groove 7a is provided with a notch 7b, from which the protrusion 9a is inserted into both grooves 7, 7a, and the protrusion 9a and both grooves 7, 7a are engaged. You can. Moreover, 10 is an annular step part, and is rotatably engaged with an annular retaining step part 4a provided at the tip of the cap 4. Therefore, if you pull the cap 4 backward, the feeding base 8
can be removed integrally from the core pipe 3. Incidentally, the cap 4 is formed with a slit 4b so that it can be smoothly inserted into the feeding base 8 from the rear. Furthermore, this feeding base 8 is formed so that the projecting piece 8a engages with the axial groove 1a of the outer cylinder 1 and can slide in the axial direction but cannot rotate. Note that the rotation prevention means of the feeding base 8 with respect to the outer cylinder 1 may have a rotation prevention structure in which both of them are polygonal. Further, the eraser holder 9, which is slidable in the axial direction with respect to the feeding base 8 and the cap 4, has a protrusion 9a formed at its tip that engages with the helical groove 7. A receiving part 9b that supports the eraser 5 at the rear of the eraser holder 9 has a claw part (in this embodiment, two parts are formed) that engage with the axial groove 4c of the cap 4 (see FIG. 3). ) 9c is formed and is prevented from rotating. Here, the eraser holder 9 is also formed with a slit 9d so that it can be smoothly inserted into the feeding base 8 from the rear. The number of the erasers is not limited as long as the base 9 can be prevented from rotating.The eraser 5 press-fitted into the eraser holder 9 has a small protrusion 9e integrally formed on the inner periphery of the claw part 9c.
The eraser 5 is stuck in, and the eraser 5 is prevented from being removed. Further, the spiral groove 7 may be either a single groove or a double groove.
Then, the spiral groove 7 is made into a single groove, and the protrusion 9a is formed at 180°.
Alternatively, the spiral grooves 7 may be provided with two grooves, and the two protrusions 9a may be placed at positions facing each other at 180 degrees.
It may be provided at a position shifted by one pitch or half a pitch in degrees. Next, the assembly operation of this eraser feeding mechanism 6 will be explained. First, the retaining step portion 4a of the cap 4 is engaged with the annular step portion 10 of the feeding base 8 to connect the two. At this time, the diameter of the front of the cap 4 is expanded by the slit 4b, allowing smooth assembly of both.Next, the eraser holder 9 with the eraser 5 attached is inserted into the axial groove 4a of the cap 4 and the eraser holder. The eraser holder 9 with the eraser 5 inserted therein is inserted from the rear of the cap 4 while engaging the claws 9c of 9. Here, too, the diameter of the front of the eraser holder 9 is expanded by the slit 9d, so that assembly is performed smoothly. After the eraser dispensing mechanism 6 is assembled in this way, the dispensing base 8 is fitted to the rear end of the core pipe 3, and the assembly operation is completed. Next, the operation of inserting and removing the eraser 5 will be explained. When the cap 4 is rotated with respect to the outer cylinder 1, the rotational force is transmitted from the axial groove 4a of the cap 4 to the claw portion 9C of the eraser holder 9. On the other hand, the feeding base 8 is prevented from rotating relative to the outer cylinder 1 by a protruding piece 8a that engages with the axial groove 1a of the outer cylinder 1. Therefore, the protrusion 9a of the eraser 5 is rotated with respect to the spiral groove 7 by the rotational force. Then, due to the feeding action of the spiral groove 7 and the protrusion 9a, the eraser 5 is moved in the direction of the arrow, which is the axial direction of the outer cylinder 1, while being guided by the claw portion 9C and the axial groove 40. Then, the eraser 5 attached via the eraser holder 9 is taken in and out from the rear end 4a of the cap 4 in the axial direction, which is the arrow direction. When replacing the core S, if you pull the cap 4 somewhat strongly against the outer cylinder 1 in the axial direction of arrow C', the annular step l
Due to the engagement between O and the engagement step 4a, the eraser holder 9 is removed from the lead vibrator 3, so the cap 4 can be removed from the outer tube 1 in the direction of the arrow, and the refill S is inserted into the lead pipe 3. be able to. Next, in the lead feeding operation of this writing instrument, if the cap 4 is knocked, the knocking force is changed from the cap 4 to the feeding base 8.
→It is transmitted in the order of core pipe 3. Here, since the feeding base 8 is slidable in the axial direction with respect to the axial groove 1a of the outer cylinder 1, the cap 4 and the feeding base 8
, the eraser holder 9, the eraser 5, and the entire lead pipe 3 move forward, allowing a normal lead feeding operation to be performed. 4 and 5 show known rotary type feed-out mechanisms B and C in place of the knock-type lead feed mechanism A shown in FIG. 1, and details of these rotary type feed-out mechanisms B and C. This is described in the applicant's previous publication II (Utility Application No. 62-91654). Here, the only difference between the rotary feeding mechanisms B and C is whether or not they have a return spring 15 shown in FIG. Further, as shown in FIGS. 4 and 5, a core removal prevention device 16 is provided at the tip of the core pipe 3. FIG. 6 shows a second embodiment of the mechanical pencil according to the invention. The difference between this second embodiment and the first embodiment described above is only in the rotatable retaining means between the cap 4 and the feeding base 8. That is, in this second embodiment, a protruding protrusion piece 12 is provided on the side of the feeding base 8 that rotatably engages with the annular retaining step 4a of the cap 4, as shown in FIG. There is. This protrusion piece 12 is formed of an elastic piece that can be bent around the fulcrum 12a. Therefore, when assembling the cap 4 to the dispensing base 8, the cap 4 is inserted from the front end of the dispensing base 8 toward the rear side. The incision and protrusion piece 12 is reduced in diameter in the radial direction and can be moved smoothly, and after that, it returns to its original state again, and in that case, the connection between the two will not be inadvertently released. . This second embodiment also operates in exactly the same way as the first embodiment. In the above embodiment, a mechanical pencil has been described, but the core pipe 3 can be replaced with an ink pipe and the invention can be applied to a writing instrument such as a ballpoint pen in exactly the same way.
