<Embodiment 1>

  A side knock type writing instrument (hereinafter simply referred to as “writing instrument”) 1 according to Embodiment 1 of the present invention will be described with reference to FIGS. In the following description, the side where the knock (operation lever) 11 is provided is the front of the writing instrument 1.

  1 to 4, FIG. 1 is a perspective view of the writing instrument 1 as viewed from diagonally upward on the front side. FIG. 1A shows a state where the knock 11 is at the home position P1 and the character 13 is not deformed. (B) shows a state where the knock 11 is pushed down to the pressed position P2 and the character 13 is deformed, and (c) shows an exploded perspective view. 2A is a front view of the writing instrument 1 showing a state in which the knock 11 is at the home position P1 and the lead 16 is retracted, and FIG. 2B is a view taken along the line B-B in FIG. FIG. 3A is a front view of the writing instrument 1 showing a state in which the knock 11 is pushed down to the pressing position P2 and the lead 16 is taken out, and FIG. 3B is a BB line arrow in FIG. FIG. FIG. 4A is a front view of the writing instrument 1 showing a state where the knock 11 is at the home position P1 and the lead 16 is extended, and FIG. 4B is a view taken along the line B-B in FIG. FIG. Here, FIG. 2 shows a non-use state of the writing instrument 1, FIG. 3 shows a transient state when the lead 16 is put out, and FIG. 4 shows a use state of the writing instrument 1. 2 to 4 show a state where the base 12 and the character 13 are removed.

  As shown in FIG. 1, the writing instrument 1 includes a body (writing instrument main body) 10, a knock (operation lever) 11, a pedestal 12, a character 13, and a pressing member 14. The character 13 refers to a figure imitating a person, a doll, animals and plants, a toy, a vehicle, or the like, and any object can be a figure.

  Here, since the centering mechanism of the writing instrument 1 according to the present embodiment, that is, the mechanism for putting in and out the core 16, employs a well-known configuration and method, it can be simply described with reference to FIGS. explain.

  As shown in FIG. 2B, the body 10 is formed in a cylindrical shape that extends from the distal end portion (lower end portion) to the proximal end portion (upper end portion) along the axis S. In the body 10, the inner peripheral surface 10a is preferably cylindrical, but the outer peripheral surface 10b may be a regular hexagon, a regular octagon, or the like in addition to the cylindrical shape. A guide groove 10c is formed on the side surface on the upper end side of the body 10 so as to guide the movement of the knock 11 in the vertical direction (axial direction), that is, the downward pressing operation and the returning operation upward. Yes. In addition, through ribs (not shown) and stop ribs (not shown) oriented in the vertical direction are alternately formed in the circumferential direction in the vicinity of the height corresponding to the lower end of the knock 11 on the inner peripheral surface 10a of the body 10. ing. A tapered cap 15 is attached to the lower end of the body 10. A through-hole 15a is formed in the cap 15 in the vertical direction, and a tip 16a of a core (refill) 16 is put in and out from the through-hole 15a. The core 16 is urged upward by a core push-up spring 17.

  A rotary cam 18 is rotatably covered on the upper end of the core 16, and a slide cam 19 that is not rotatable and is movable in the vertical direction is further covered on the rotary cam 18. The slide cam 19 and the rotary cam 18 are in contact with each other on an inclined surface (not shown), and when the slide cam 19 descends, a rotational force acts on the rotary cam 18 with the axis S as a reference. However, the rotating cam 18 does not rotate while the guided portion (not shown) of the rotating cam 18 is guided in the vertical movement by the above-described through rib. When the slide cam 19 is further lowered, the rotating cam 18 moves to the stop rib while its guided portion is rotated away from the through rib. Thereby, the tip 16a of the core 16 protrudes from the cap 15 as described later.

  The slide cam 19 is pushed down by a joint (interlocking mechanism) 20 integral with the knock 11. The joint 20 is urged upward by a knock push-up spring 21 whose lower end is engaged with the upper end of the stop rib.

  When the knock 11 arranged at the home position P1 shown in FIG. 2 is pushed down by the user's finger (manual), the joint 20 integrated with the knock 11 descends against the urging force of the knock push-up spring 21, and slides. The cam 19 is pushed down. The pushed-down slide cam 19 pushes down the rotating cam 18 while applying a potential rotating force against the urging force of the core push-up spring 17. And if the rotation cam 18 remove | deviates from a through rib, it will move to a stop rib, rotating.

  FIG. 3 shows a state in which the knock 11 is pushed down to the pressing position (P2), the rotating cam 18 moves to the stop rib, and the tip 16a of the core 16 protrudes from the through hole 15a of the cap 15.

  When the user releases his / her finger from the knock 11 from the state shown in FIG. 3, the rotating cam 18 is pushed up by the core push-up spring 17, rotates while returning slightly upward, and fits in the stop rib. As a result, the core 16 is held in a state where the tip 16a protrudes from the through hole 15a of the cap 15. On the other hand, the knock 11 is biased upward by the knock push-up spring 21 and returns to the home position P1. This state is the state shown in FIG. 4 and is a state where writing is possible.

  When writing is finished and then the knock 11 is pushed down again, the rotary cam 18 is pushed down by the slide cam 19 through the joint 20, is removed from the stop rib, rotates, and moves to the next through rib. As a result, the lead 16 is retracted, and the knock 11 returns to the home position P1.

  Next, the characteristic part of this embodiment is explained in full detail.

  As shown in FIG. 2B, the joint 20 has a large-diameter cylindrical large-diameter portion 20a in the lower half and a small-diameter cylindrical small-diameter portion 20b in the upper half. A wall 20c is formed between them. Part of the upper portion of the knock 11 on the back side (the body 10 side) is engaged with the large diameter portion 20a. Further, an engaging portion 20d protruding inward is provided on the upper end of the small diameter portion 20b over substantially the entire circumference. Further, in the small diameter portion 20b, a vertical slit (not shown) is formed, and the small diameter portion 20b protrudes upward from the opening 10d at the upper end of the body 10 (for example, during assembly). The engaging portion 20d is opened, and a locking portion 14d of the pressing member 14 described later can be inserted into the engaging portion 20d. The joint 20 is configured integrally with the knock 11 and moves near the upper end of the body 10 as the knock 11 is pushed down from the home position P1 to the pressed position P2 and returned from the pressed position P to the home position P2. It goes down and up.

  An opening 10d is provided at the upper end of the body 10, and a base 12 is fitted into the opening 10d as shown in FIG. 1 (c). The pedestal 12 includes a fitting portion 12a fitted into the opening 10d, and a substantially disc-shaped support portion 12b having a larger diameter and a larger area than the fitting portion 12a. The fitting portion 12a is formed in a cylindrical shape, and its outer peripheral surface is fitted to the inner peripheral surface 10a in the upper portion of the body 10, and the inner peripheral surface and the outer peripheral surface of the small-diameter portion 20b of the joint 20 described above. A small gap 20b of the joint 20 can be moved inside the fitting portion 12a by providing an appropriate gap therebetween. The support portion 12b reliably supports the character 13 placed on the upper surface thereof. A through hole 12c is formed at a substantially central portion of the support portion 12b so as to penetrate the pressing member 14 in the vertical direction. Further, a notch portion 12d is provided on the front side of the support portion 12b so that the knock 11 can be easily operated. The pedestal 12 is integrally configured as a whole by, for example, a hard synthetic resin.

  In the illustrated example, the character 13 is an elastically deformable parent frog formed of a soft synthetic resin. The body 13a has a head 13b projecting an eyeball 13c, and a front leg 13d and a rear leg 13e. The body 13a is provided with a through hole 13f penetrating in the vertical direction substantially at the center. The entire parent frog is integrally formed, and the rear leg 13e is fixed (adhered) to one end of the support 12b of the base 12 (the end opposite to the notch 12d). On the other hand, the front leg 13d is formed longer than the rear leg 13e, extends downward from the vicinity of the head 13b, and the front end is fixed to the other end of the support portion 12b, that is, near the notch 12d. The middle part is free. That is, as will be described later, when the body 13a is pressed downward substantially at the center by the pressing portion 14a of the pressing member 14, the parent frog is lowered so that the head 13b side bows with respect to the rear leg 13e side. And the front leg 13d is bent.

  The entire pressing member 14 is formed in a substantially rod shape by, for example, a hard synthetic resin. The pressing member 14 has a pressing portion 14 a larger than the through-hole 13 f of the character 13 on the upper portion protruding above the character 13. In the illustrated example, the pressing portion 14 a is given the shape of a child frog that forms part of the character 13. The child frog is bonded so as to cover the back of the parent frog so that the parent frog does not leave the back when the parent frog deforms. Below the pressing portion 14a of the pressing member 14, there is a through portion 14b that passes through the through hole 13f of the character 13 and the through hole 12c of the pedestal 12, and further below that there is a small diameter portion 14c that is smaller in diameter than the through portion 14b. A locking portion 14d having a larger diameter than that of the small diameter portion 14c is formed.

  As shown in FIG. 2B, the pressing member 14 is formed so that the small diameter portion 14c can move up and down inside the engaging portion 20d of the joint 20 and the engaging portion 14d is caught by the engaging portion 20d. Has been. Further, in the illustrated example, an idle swing section D is formed between the engaging portion 20d on the joint 20 side and the locking portion 14d on the pressing member 14 side. By adjusting the length of the idle swing section D, the stroke amount of the pressing member 14 can be adjusted with respect to the stroke amount from the home position P1 of the knock 11 to the pressed position P2. That is, if the idle swing section D is configured to be 0, the stroke amount of the pressing member 14 can be made the same as the stroke amount of the knock 11, and the pressing member can be increased by making the idle swing section D large. The stroke amount of 14 can be reduced. Here, the stroke amount of the pressing member 14 may be set as appropriate in accordance with the size of the character 13 and the desired deformation or posture change. In the case where the idling section D is set to a non-zero value, the knock 11 starts to push down the pressing member 14 only after being pushed down by the stroke amount corresponding to the idling section D during the pushing operation. The deformation of the character 13 by the pressing portion 14a can be started. That is, since a time delay corresponding to the time for the knock 11 to move in the idle swing section D occurs until the pressing portion 14a deforms the character 13, the user can be surprised. Since the user thinks that the deformation of the character 13 is started with the start of the pushing-down operation of the knock 11, a time delay occurs until the deformation of the character 13. Recognize that the operation did not.

  The writing instrument 1 having the above-described configuration operates as follows. In addition, about the operation | movement of taking in / out of the core 16, description is abbreviate | omitted suitably.

  When the writing instrument 1 is used for writing, the user holds the body 10 with four fingers other than the palm and the thumb, hooks the thumb on the upper end of the knock 11, and pushes down the knock 11. Thereby, knock 11 starts to descend from home position P1 shown in FIG. 2, and joint 20 integrated with knock 11 also begins to descend. At this time, since the slide cam 19 and the rotary cam 18 are pushed down by the joint 20, the push-down operation of the lead 16 is started when the knock 11 is pushed down. On the other hand, the pressing member 14 does not start to descend until the idle swing section D disappears. In the pressing member 14, when the knock 11 and the joint 20 start to descend and the joint 20 finishes descending the idle swing section D, the engaging portion 20d of the joint 20 is engaged with the locking portion 14d. The pressing member 14 starts to descend only by this engagement. After the engagement, the pressing member 14 descends in response to the pushing operation of the knock 11, and the pressing portion (child frog) 14 a gradually crushes the character (parent frog) 13. Thereby, since the rear frog 13e side is fixed to one end of the support portion 12b of the pedestal 12, the parent frog swings downward (droops) so that the head 13b side bows. The front leg 13d is bent. FIG. 1B shows this state.

  Thus, when the user pushes the knock 11 from the home position P1 shown in FIG. 1A to the pressed position P2 shown in FIG. 1B, the character (parent frog) 13 raises the head 13b. From the posture in which the front leg 13d is extended, the head 13b is lowered and bowed while bowing. Such a movement of the character 13 is organic because the character 13 itself is deformed and changed its posture, unlike the conventional one in which the character rotates inorganically (mechanically). , It will be surprising and interesting. Further, since the idle swing section D is provided as described above, the motion of the knock 11 and the motion of the character 13 do not necessarily match, and thus the unexpectedness can be further enhanced.

  After the knock 11 is placed at the pressed position P2 and the lead 16 is released, when the user lifts the finger from the knock 11, the knock 11 rises and returns to the home position P1, and the character 13 is also deformed or postured. The change is released and the original posture is restored. At this time, the elastic force of the character 13 itself is further combined based on the idle swing section D, and the return operation of the character 13 is preceded, contrary to the pushing-down operation of the knock 11, and thereafter, with a time delay, The return operation of knock 11 is completed.

  Thus, the fact that the action of the knock 11 and the deformation and return action of the character 13 do not correspond one-to-one results in further enhancement of interest for the user. As described above, if the idle swing section D is set to 0, or if the knock 11 and the pressing member 14 are directly engaged, the operation of the knock 11 and the operation of the pressing portion 14a of the pressing member 14 are paired. 1, and accordingly, the deformation and posture change of the character 13 are started with the start of the push-down operation of the knock 11.

  In the above-described embodiment, with respect to the pressing member 14 and the pedestal 12, the inner diameter of the through hole 12 c of the pedestal 12 is larger than the through portion 14 b of the pressing member 14, and an appropriate gap is provided between them. . As the pressing member 14 descends, the parent frog swings so that the head 13b side bows with respect to the rear leg 13e side, so the pressing member 14 does not descend straight, but engages on the lower end side. An operation in which the upper end pressing portion 14a swings in the front-rear direction with respect to the vicinity of the stop portion 14d is also added. For this reason, by providing an appropriate gap as described above, the operation of the pressing member 14 can be made smooth, and the swinging operation of the parent frog can be made more realistic.

  In the writing instrument 1 described above, the pressing portion 14a of the pressing member 14 is a child frog that rides on the back of the character (parent frog) 13 so as to form a part of the character. While maintaining the consistency of the design, it can increase the fun.

  With reference to FIG. 5, the writing instrument 2 which is a modification of the writing instrument 1 is demonstrated. FIGS. 5A and 5B are perspective views of the writing instrument 2 as viewed from diagonally upward on the front side. FIG. 5A shows a state where the knock 11 is at the home position P1 and the character 23 is not deformed, and FIG. Shows a state where the character 23 is deformed by being pushed down to the pressing position P2, and (c) shows an exploded perspective view. Note that the writing instrument 2 shown in the figure is the same as the writing instrument 1 shown in FIGS. 1 to 4 except for the base 22, the character 23, and the pressing member 24. Description will be omitted as appropriate.

  As shown in FIG. 5, the character 23 is composed of a substantially spherical figure imitating the face of a doll. Eyes 23b and mouths 23c are drawn on the face 23a. The pedestal 22 has a support portion 22b having a size corresponding to the bottom portion of the face 23, a cylindrical fitting portion 22a that fits into the opening 10d of the body 10, and a see-through penetrating through substantially the center of the support portion 22b. It has a hole 22c. Moreover, the press part 24 has the press part 24a which imitated the hat with a hook in the upper end part. Except for the pressing portion 24a, the through portion 24b, the small diameter portion 24c, and the locking portion 24d are the same as the through portion 14b, the small diameter portion 14c, and the locking portion 14d shown in FIG.

  In the writing instrument 2 shown in FIG. 5, the pressing portion (cap) 24 a of the pressing member 24 is lowered in response to the pressing operation of the knock 11, and the character (face) 23 is crushed. At this time, as the face 23a is crushed up and down, the eyes 23b and the mouth 23c are also crushed up and down and spread in the left-right direction, creating a very interesting face 23a.

  On the other hand, as the knock 11 returns, the character 23 also returns to the original face 23a. In this example, with the deformation of the character 23, the facial expression of the face 23a changes interestingly. In this example as well, a time delay may be generated by providing the idle swing section D as described above. In this example, for example, the face 23a of the character 23 may be formed vertically long, the idling section D may be set to 0, and the deformation amount of the face 23a may be increased.

  With reference to FIG. 6, the writing instrument 3 which is a modification of the writing instrument 1 is demonstrated. FIGS. 6A and 6B are perspective views of the writing instrument 3 as viewed from diagonally upward on the front side. FIG. 6A shows a state where the knock 11 is at the home position P1 and the character 33 is not deformed, and FIG. Shows a state where the character 33 is deformed by being pushed down to the pressing position P2, and (c) shows an exploded perspective view. The writing instrument 3 shown in the figure is the same as the writing instrument 1 shown in FIGS. 1 to 4 except for the pedestal 32, the character 33, and the pressing member 34. To do.

  As shown in FIG. 6, the character 33 is composed of a figurative object imitating a doll from which legs are omitted. The body 33 a is formed in a columnar shape, and two arms 33 b extend from the body 33 a, and the tip of the arm 33 b is fixed to the support portion 32 b of the pedestal 32. Moreover, the pressing part 34 has a spherical pressing part 34a imitating a face at the upper end. Except for the pressing portion 34a, the through portion 34b, the small diameter portion 34c, and the locking portion 34d are the same as the through portion 14b, the small diameter portion 14c, and the locking portion 14d shown in FIG.

  In the writing instrument 3 shown in FIG. 6, the pressing portion (face) 34 a of the pressing member 34 descends in response to the pressing operation of the knock 11 to crush the body 33 a of the character 33. At this time, as the body 34a is crushed up and down, the body 34a expands in the front-rear and left-right directions and becomes thicker.

  On the other hand, the character 33 also returns to the original slim body 33a with the return motion of the knock 11. In this example, as the character 33 is deformed, the body 33a changes interestingly as the body 33a becomes thin or thick. In this example as well, a time delay may be generated by providing the idle swing section D as described above. In this example, for example, the torso 33a of the character 33 is further formed to be vertically long, the idle swing section D is set to 0, and the difference between the torso around when the torso 33a is thin and fat is increased. Good.
