【０００８】[0008]
請求項１または請求項２記載の棒状物繰り出し容器付き筆記具では、先軸また は外筒の側面に形成された側面に取り付けられたノックレバーをサイドノックす ると、スライダーが前方へ摺動し、スライダーに連動して筆記体送り出し機構が 作動する。ノックレバーは先軸または外筒の側面に取り付けられているために、 筆記中に筆記具を持ち換えることなく、操作することができる。 また、棒状物繰り出し容器は、案内筒を外筒に対して回転させると、ねじ部に よって棒状物ホルダが軸方向に移動するため、棒状物を繰り出すことができる。 請求項３の棒状物繰り出し容器付き筆記具では、案内筒を外筒に対して回転さ せると、外筒に回転不能にされた雌ねじ部材に対して案内筒が回転して、雌ねじ 部材の雌ねじと案内筒の雄ねじとの螺合によって、雌ねじ部材が軸方向に移動す る。そして、雌ねじ部材と軸方向移動不能にされた棒状物ホルダが雌ねじ部材と 一緒に軸方向に移動するので、棒状物を外筒先端から突出させることができる。 また逆に回転させると、棒状物が没入する。 In the writing implement with a stick-shaped object feeding container according to claim 1 or 2, when the knock lever attached to the side of the front shaft or the outer cylinder is knocked, the slider slides forward. The cursive delivery mechanism operates in conjunction with the slider. Since the knock lever is attached to the front shaft or the side of the outer cylinder, it can be operated without changing the writing instrument during writing. In addition, when the guide cylinder is rotated with respect to the outer cylinder, the rod-shaped object holder is moved in the axial direction by the screw portion, so that the rod-shaped object can be fed out. In the writing instrument with the stick-shaped object feeding container according to the third aspect, when the guide cylinder is rotated with respect to the outer cylinder, the guide cylinder rotates with respect to the female screw member that cannot be rotated by the outer cylinder, and the female screw of the female screw member is rotated. The female screw member moves in the axial direction by being screwed with the male screw of the guide cylinder. Then, since the female screw member and the rod-shaped object holder that is immovable in the axial direction move in the axial direction together with the female screw member, the rod-shaped material can be projected from the distal end of the outer cylinder. When rotated in the opposite direction, the rod-like object sinks.
【０００９】 雄ねじが案内筒の外周にあり、その雄ねじに螺合する雌ねじ部分の長さは短く てよいため、その製造は簡単になる。即ち、雌ネジ部分を成形する際にコアピン を回転させる必要がなく、製造コストを低減させることができる。 また、棒状物は案内筒の内側に存在することができ、棒状物のための空間が雄 ねじによって占有されないため、棒状物の長さを十分長くとることができる。Since the male screw is provided on the outer circumference of the guide cylinder and the length of the female screw portion to be screwed to the male screw may be short, the manufacture thereof is simplified. That is, it is not necessary to rotate the core pin when forming the female screw portion, and the manufacturing cost can be reduced. Further, since the rod-shaped object can be present inside the guide tube and the space for the rod-shaped object is not occupied by the external thread, the length of the rod-shaped object can be made sufficiently long.

以下、図面を参照して本考案の実施例を説明する。 図１は、本考案の第１実施例を示す。以下の実施例において、棒状物繰り出し 容器がシャープペンシルの後部と結合した棒状物繰り出し容器付きシャープペン シルについて説明するが、これに限られず、ボールペン等の筆記具と結合するこ とができる。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a first embodiment of the present invention. In the following examples, a mechanical pencil with a stick-shaped object dispensing container in which a stick-shaped object dispensing container is connected to the rear part of a mechanical pencil will be described. However, the present invention is not limited to this, and it can be combined with a writing instrument such as a ballpoint pen.
【００１１】 棒状物繰り出し容器１０は、主に、外筒１２と、案内筒１４と、棒状物ホルダ １６と、雌ねじ部材１８とを備える。 外筒１２は、内周が多角形（本実施例では、８角形）形状をした筒状体で、そ の内周前方には、環状突起１３が設けられる。環状突起１３は、後方にテーパー が形成されている。The rod-shaped material feeding container 10 mainly includes an outer cylinder 12, a guide cylinder 14, a rod-shaped material holder 16, and a female screw member 18. The outer cylinder 12 is a cylindrical body having an inner periphery of a polygon (in this embodiment, an octagon) shape, and an annular projection 13 is provided in front of the inner periphery. The annular projection 13 has a tapered rearward portion.
【００１２】 案内筒１４は、図２に示したように、その後端に環状ストッパ２６を、前方に 径方向に撓むことのできる突出片２７を有しており、外筒１２に対して後方から 案内筒１４を挿入することによって、突出片２７が環状突起１３のテーパに従っ て内方に撓み、環状突起１３を越えて再び突出片２７が戻って環状突起１３に当 接する。従って、案内筒１４は、環状ストッパ２６と突出片２７によって外筒１ ２に対して軸方向移動不能に回転可能に嵌挿される。案内筒１４は、突出片２７ と環状ストッパ２６との間に軸方向に伸びる２つの案内スリット２２を有し、案 内スリット２２の延長は環状ストッパ２６の内側の溝となり、環状ストッパ２６ の末端まで伸びている。また、案内筒１４の外周には、雄ねじ２４である螺旋溝 が形成される。さらに、案内筒１４の先端２８は、後述のシャープペンシルの先 軸６０と回転不能に嵌合するため多角形に形成される。As shown in FIG. 2, the guide cylinder 14 has an annular stopper 26 at its rear end and a protruding piece 27 that can bend radially forward. By inserting the guide cylinder 14 from above, the protruding piece 27 bends inward according to the taper of the annular projection 13, and the protruding piece 27 returns again beyond the annular projection 13 and contacts the annular projection 13. Therefore, the guide cylinder 14 is rotatably fitted to the outer cylinder 12 by the annular stopper 26 and the protruding piece 27 so as to be axially immovable. The guide cylinder 14 has two guide slits 22 extending in the axial direction between the protruding piece 27 and the annular stopper 26, and the extension of the inner slit 22 becomes a groove inside the annular stopper 26, and the end of the annular stopper 26 It is growing up. A spiral groove, which is a male screw 24, is formed on the outer periphery of the guide cylinder 14. Further, the distal end 28 of the guide cylinder 14 is formed in a polygonal shape so as to be non-rotatably fitted to a tip shaft 60 of a mechanical pencil described later.
【００１３】 棒状物ホルダ１６は、図３に示したように、ホルダ本体２９と、前記２つの案 内スリット２２に摺動可能に係合する２つの係合部３０からなる。係合部３０は 、その先端内面に棒状物２０を保持するための爪３１と、その外面に雌ねじ部材 １８を収容するための２つの突起３２とを備える。但し、棒状物の保持は、必ず しも係合部３０で行わなくてもよく、筒形のホルダ本体２９内に棒状物２０を挿 入するようにしてもよい。ホルダ本体２９には、軸方向に貫通したスリット３４ が形成され、組み立て時にスリット３４を利用して棒状物ホルダ１６を内方に撓 ませることで、案内筒１４の案内スリット２２から棒状物ホルダ１６を嵌挿させ て、案内スリット２２に係合部３０を係合させることができる。As shown in FIG. 3, the rod holder 16 includes a holder main body 29 and two engaging portions 30 slidably engaged with the two plan slits 22. The engaging portion 30 has a claw 31 for holding the rod 20 on the inner surface of the distal end thereof, and two protrusions 32 for accommodating the female screw member 18 on its outer surface. However, the holding of the rod-like object does not necessarily have to be performed by the engaging portion 30, and the rod-like object 20 may be inserted into the cylindrical holder body 29. A slit 34 penetrating in the axial direction is formed in the holder body 29, and the rod holder 16 is bent inward by using the slit 34 during assembly, so that the rod holder 16 can be moved from the guide slit 22 of the guide cylinder 14. Can be engaged to engage the engagement portion 30 with the guide slit 22.
【００１４】 雌ねじ部材１８は、図４に示したように、外筒１２の多角形の内周に摺動可能 な多角形の外周を持ち、且つその内周には、約半ピッチ分の雌ねじ３６が形成さ れる。雌ねじ部材１８は、組み立て時に既に棒状物ホルダ１６が嵌挿された案内 筒１４に対して、その先端２８を通り、内方に撓むことができる突出片２７を抜 けて、案内筒１４の雄ねじ２４と雌ねじ３６を螺合させる。さらにスリット３４ を利用して棒状物ホルダ１６を内方に撓ませることで突起３２の片方を抜けて、 突起３２と突起３２の間に収容される。このようにして組み立てられた案内筒１ ４、棒状物ホルダ１６、雌ねじ部材１８を前述のように外筒１２の後方から挿入 することで、棒状物繰り出し容器１０が組み立てられ、雌ねじ部材１８の多角形 の外周は、外筒１２の多角形の内周と摺動可能に取り付けられる。尚、雌ねじ部 材１８の外周と外筒１２の内周は、多角形でなくキー溝とキーの関係でもよい。As shown in FIG. 4, the female screw member 18 has a polygonal outer periphery slidable on the polygonal inner periphery of the outer cylinder 12, and has a female screw of about half a pitch on its inner periphery. 36 are formed. The female screw member 18 pulls out a protruding piece 27 that can be bent inward through the distal end 28 of the guide cylinder 14 into which the rod-shaped object holder 16 has already been inserted at the time of assembly. The male screw 24 and the female screw 36 are screwed. Further, the rod holder 16 is bent inward by using the slit 34 so that one of the projections 32 is removed and the rod holder 16 is accommodated between the projections 32. By inserting the guide cylinder 14, the rod holder 16, and the female screw member 18 assembled as described above from the rear of the outer cylinder 12 as described above, the rod-shaped feeding container 10 is assembled, and the multiple female screw members 18 are provided. The outer periphery of the square is slidably attached to the inner periphery of the polygon of the outer cylinder 12. Note that the outer circumference of the female screw member 18 and the inner circumference of the outer cylinder 12 may not be polygonal but may be in a relationship between a keyway and a key.
【００１５】 案内筒１４の先端２８は、シャープペンシル５６の先軸６０の後端内面に形成 された多角形と嵌合されて、回転不能に取り付けられる。尚、先端２８と先軸６ ０の関係は、キー溝とキーの関係でもよい。 先軸６０には、その側面に開口が形成され、該開口にＵ字基端を有するノック レバー６２が揺動可能に取り付けられる。先軸６０内には、バネ６６によって後 方に付勢されかつ後面に軸方向に対して傾斜したカム面を備えたスライダー６４ が配され、さらに、スライダー６４と連結されたチャック６８と、さらにチャッ ク６８の頭部外周に嵌合されてチャック６８の開閉を行うチャックリング７０と 、後方に伸びた芯タンク７２とが配される。チャック６８とチャックリング７０ は公知の芯送り出し機構（筆記体送り出し機構）を構成している。ノックレバー ６２をサイドノックすると、スライダー６４は、ノックレバー６２のＵ字基端に よってそのカム面が押し出されて前方へ摺動され、これに連動して、チャック６ ８が前方へ前進して芯が送り出される。従って、筆記中に使用者が先軸６０を持 ち換えることなく、芯を送り出すことができる。The distal end 28 of the guide cylinder 14 is fitted to a polygon formed on the inner surface of the rear end of the front shaft 60 of the mechanical pencil 56, and is attached non-rotatably. The relationship between the tip 28 and the tip shaft 60 may be the relationship between the key groove and the key. An opening is formed in the side surface of the front shaft 60, and a knock lever 62 having a U-shaped base end is swingably attached to the opening. A slider 64, which is urged rearward by a spring 66 and has a cam surface inclined in the axial direction on the rear surface, is disposed inside the front shaft 60, and further includes a chuck 68 connected to the slider 64, A chuck ring 70 fitted to the outer periphery of the head of the chuck 68 to open and close the chuck 68 and a lead tank 72 extending rearward are provided. The chuck 68 and the chuck ring 70 constitute a known center delivery mechanism (cursive delivery mechanism). When the knock lever 62 is side-knocked, the slider 64 slides forward with its cam surface pushed out by the U-shaped base end of the knock lever 62, and in conjunction with this, the chuck 68 advances forward. The wick is sent out. Therefore, the core can be sent out without the user holding the front shaft 60 during writing.
【００１６】 また、先軸６０を外筒１２に対して回転する（又は外筒１２を先軸６０に対し て回転させる）と、先軸６０と案内筒１４は回転不能であるため、外筒１２と案 内筒１４の相対回転が生じる。雌ねじ部材１８は、外筒１２に対して回転不能で あるため、雌ねじ部材１８の雌ねじ３６と案内筒１４の雄ねじ２４との螺合によ って、雌ねじ部材１８が軸方向に移動する。雌ねじ部材１８と棒状物ホルダ１６ との間では、軸方向に移動不能であるために、棒状物ホルダ１６は、雌ねじ部材 １８と一緒に軸方向に移動して、棒状物２０を環状ストッパ２６から突出させる ことができる。When the front shaft 60 is rotated with respect to the outer cylinder 12 (or when the outer cylinder 12 is rotated with respect to the front shaft 60), the front shaft 60 and the guide cylinder 14 cannot rotate. A relative rotation of the inner cylinder 14 and the inner cylinder 14 occurs. Since the female screw member 18 cannot rotate with respect to the outer cylinder 12, the female screw member 18 moves in the axial direction by screwing the female screw 36 of the female screw member 18 with the male screw 24 of the guide cylinder 14. Since it is impossible to move in the axial direction between the female screw member 18 and the rod holder 16, the rod holder 16 moves in the axial direction together with the female screw member 18 to move the rod 20 from the annular stopper 26. Can protrude.
【００１７】 また、逆方向に回転すれば、棒状物２０が軸方向の反対に移動して棒状物が没 入し、収納される。 雄ねじ２４が案内筒１４の外周にあり、その雄ねじ２４に螺合する雌ねじ３６ の部分の長さは短くてよいため、その製造は簡単になる。即ち、雌ねじ部材１８ の雌ねじ３６は、半ピッチ分程度の長さで良いので、成形時に雌ねじ部材１８の 両側から２つのコアピンを挿入することで、型抜きの際にコアピンを回転させる 必要がなくなり、製造コストを低減させることができる。Further, when the bar-shaped object 20 rotates in the opposite direction, the bar-shaped object 20 moves in the direction opposite to the axial direction, and the bar-shaped object is immersed and stored. Since the male screw 24 is provided on the outer periphery of the guide tube 14 and the length of the female screw 36 to be screwed to the male screw 24 may be short, the manufacture thereof is simplified. That is, since the female screw 36 of the female screw member 18 may have a length of about a half pitch, inserting two core pins from both sides of the female screw member 18 at the time of molding eliminates the need to rotate the core pin at the time of die cutting. In addition, the manufacturing cost can be reduced.
【００１８】 また、棒状物２０は、雄ねじ２４を備えた案内筒１４の内側に存在することが できるため、棒状物２０のための空間が雄ねじによって占有されないために、棒 状物２０の長さを長くとることができる。Further, since the rod 20 can be present inside the guide tube 14 provided with the external thread 24, the space for the rod 20 is not occupied by the external thread, so that the length of the rod 20 is Can be long.
【００１９】 次に、図５は本考案の第２実施例を示している。前実施例と同様の構成要素は 、同一番号を付し、その説明を省略する。本実施例では、外筒４２が、シャープ ペンシル５６の先軸と一体に構成される。Next, FIG. 5 shows a second embodiment of the present invention. The same components as those in the previous embodiment are denoted by the same reference numerals, and description thereof will be omitted. In the present embodiment, the outer cylinder 42 is formed integrally with the front shaft of the mechanical pencil 56.
【００２０】 案内筒４４には、図６に示したように、その後端に回転つまみ部４８と、回転 つまみ部４８の近傍に突起４９が形成されている。案内筒４４は、外筒４２の後 方から挿入されて、外筒４２の後端が回転つまみ部４８と当接し、かつ外筒４２ の突起４９と対向する位置に設けられた環状凹部４３と突起４９が弱く係合する ことで、外筒４２に対し着脱自在かつ回転可能に嵌挿される。前実施例と同様に 、軸方向に伸びる案内スリット２２の延長が、回転つまみ部４８の内側の溝とな る。As shown in FIG. 6, the guide cylinder 44 has a rotary knob 48 at its rear end and a projection 49 near the rotary knob 48. The guide cylinder 44 is inserted from the rear of the outer cylinder 42, the rear end of the outer cylinder 42 abuts on the rotary knob 48, and the annular recess 43 is provided at a position facing the projection 49 of the outer cylinder 42. When the projection 49 is weakly engaged, the projection 49 is detachably and rotatably fitted into the outer cylinder 42. As in the previous embodiment, the extension of the guide slit 22 extending in the axial direction becomes a groove inside the rotary knob 48.
【００２１】 棒状物ホルダ４６は、図７に示したように、ホルダ本体５３と案内スリット２ ２に係合する２つの係合部５４を有する。係合部５４のホルダ本体５３から延長 した部分に雌ねじ部材１８を収容するための２つの突起５５が夫々に設けられる 。係合部５４の長さは、棒状物ホルダ４６が最大限回転つまみ部４８の方へ移動 したときに、棒状物ホルダ４６の係合部５４が回転つまみ部４８に設けられた内 側の溝を越えていくらか突出するように選択されると良い。係合部５４が回転つ まみ部４８より突出することで、消耗した棒状物２０の交換が容易になる。尚、 棒状物ホルダ４６のホルダ本体５３には、前実施例と同様のスリット３４を設け てもよいが、ホルダ本体５３と突起５５の位置が軸上ずれているため、スリット を特別設けなくても案内スリット２２への挿入が可能である。As shown in FIG. 7, the rod holder 46 has a holder body 53 and two engaging portions 54 that engage with the guide slits 22. Two projections 55 for accommodating the female screw member 18 are respectively provided at portions of the engagement portion 54 extending from the holder main body 53. The length of the engaging portion 54 is such that when the rod-shaped object holder 46 moves toward the rotary knob 48 at the maximum, the engaging portion 54 of the rod-shaped object holder 46 is formed on the inner groove provided in the rotary knob 48. Should be selected to protrude somewhat beyond. Since the engaging portion 54 protrudes from the rotary knob portion 48, it becomes easy to replace the worn rod 20. The holder body 53 of the rod holder 46 may be provided with the same slits 34 as in the previous embodiment, but since the positions of the holder body 53 and the projections 55 are shifted on the axis, no special slit is required. Can also be inserted into the guide slit 22.
【００２２】 また、芯タンク７２の後端には、漏斗状の芯受け７４が取り付けられる。 本実施例では、前実施例と同様にノックレバー６２をサイドノックすると芯が 送り出され、また、回転つまみ部４８を外筒４２に対して回転することによって 前実施例と同様に棒状物２０の出し入れを行うことができる。 さらに、本実施例のシャープペンシル５６で、芯の補充を行うときには、案内 筒４４の回転つまみ部４８を後方に引っ張ることによって、環状凹部４３と突起 ４９の係合が外れる。そして、外筒４２の後方から芯を挿入することができる。 このとき、芯受け７４があるために、確実に芯が芯タンク７２に補充される。A funnel-shaped core receiver 74 is attached to the rear end of the core tank 72. In the present embodiment, when the knock lever 62 is side-knocked in the same manner as in the previous embodiment, the lead is fed out. In addition, by rotating the rotary knob 48 with respect to the outer cylinder 42, the rod 20 Can be put in and out. Further, when refilling the lead with the mechanical pencil 56 of this embodiment, the engagement between the annular recess 43 and the projection 49 is released by pulling the rotary knob 48 of the guide cylinder 44 backward. Then, the core can be inserted from behind the outer cylinder 42. At this time, since the core receiver 74 is provided, the core is reliably refilled into the core tank 72.
【００２３】 尚、上記各実施例において、雌ねじ３６を約半ピッチ分の突起、雄ねじ２４を 螺旋溝として図示したが、逆の関係であってもよく、雌ねじ３６を短いピッチの の溝、雄ねじ２４を螺旋突起としても良い。この場合雌ねじ部材１８の成形時に コアピンを多少回転させなければならないことになるが、それでも従来に比べれ ば十分その製造時間と手間を削減することができる。In each of the above embodiments, the female screw 36 is shown as a protrusion for about a half pitch, and the male screw 24 is shown as a spiral groove. However, the reverse relationship may be adopted. 24 may be a spiral projection. In this case, the core pin must be slightly rotated when the female screw member 18 is formed. However, the manufacturing time and labor can be sufficiently reduced as compared with the related art.
【００２４】 また、上記各実施例において、雄ねじ２４である螺旋溝は１条螺旋として図示 したが、２条以上の多条螺旋であっても本考案の範囲内であることはいうまでも ない。その場合には、複数の短いピッチの雌ねじ３６を設ければよく、同じ多条 螺旋を持つ従来品に比べれて、その製造時間と手間を削減することができる。多 条螺旋とした場合には、回転の安定性が増すという効果を有する。In each of the above embodiments, the spiral groove as the male screw 24 is illustrated as a single spiral, but it is needless to say that a spiral spiral having two or more threads is within the scope of the present invention. . In this case, a plurality of female screws 36 having a short pitch may be provided, and the manufacturing time and labor can be reduced as compared with a conventional product having the same multi-spiral. The use of a multi-helical spiral has the effect of increasing rotational stability.
【００２５】[0025]
以上説明したように、請求項１または請求項２に係る考案によれば、ノックレ バーは先軸または外筒の側面に取り付けられているために、筆記中に筆記具を持 ち換えることなく、筆記体送り出しのための操作をすることができる。 また、棒状物繰り出しに際して、案内筒は外筒に対して移動する必要がなく、 その代わりに棒状物ホルダが外筒に対して軸方向に移動するため、棒状物のスト ロークに対して案内筒の長さを長くする必要はない。従って、棒状物に対する棒 状物繰り出し容器の全長の長さを比較的短くできる。 また、請求項３に係る考案によれば、雄ねじが案内筒の外周にあり、その雄ね じに螺合する雌ねじ部分の長さは短くてよいため、その製造は簡単になる。即ち 、従来のように成形時にコアピンを回転させる必要がなくなるため、製造コスト を低減させることができる。 As described above, according to the invention of claim 1 or 2, since the knock lever is attached to the front shaft or the side surface of the outer cylinder, the writing lever can be written without changing the writing tool during writing. An operation for body delivery can be performed. In addition, the guide cylinder does not need to move with respect to the outer cylinder when the rod-shaped object is fed out. Instead, the rod-shaped object holder moves in the axial direction with respect to the outer cylinder. There is no need to increase the length of. Therefore, the length of the entire length of the rod-shaped material feeding container with respect to the rod-shaped material can be relatively shortened. According to the third aspect of the present invention, since the male screw is provided on the outer periphery of the guide cylinder and the length of the female screw portion to be screwed with the male screw can be short, the manufacture is simplified. That is, since there is no need to rotate the core pin at the time of molding as in the related art, manufacturing costs can be reduced.
【００２６】 また、棒状物は案内筒の内側に存在することができ、棒状物のための空間が雄 ねじによって占有されないために、従来に比べ棒状物の長さを十分長くとること ができる。Further, since the rod-shaped object can be present inside the guide cylinder and the space for the rod-shaped object is not occupied by the external thread, the length of the rod-shaped object can be made sufficiently longer than before.
