本案は一本の軸筒の両端開口部から別個の筆記
体がそれぞれ出没するように構成した両頭筆記具
における筆記体の出没装置の改良に関する。[Detailed Description of the Invention] The present invention relates to an improvement of a device for emitting and retracting a writing body in a double-ended writing instrument configured such that separate writing bodies emerge and retract from openings at both ends of a single barrel.

立作業が繁雑になり、コスト高につながつてい
た。 However, in conventional double-ended writing instruments of this kind, there are many that have separate and independent mechanisms for each writing body, and in this case, it is inevitable that the number of parts will increase, and as a result, the assembly work will be complicated. It became complicated and led to high costs.
また、実開昭51−51038号や、実開昭57−11081

いものであつて、合理性に欠けるものである。 Also, Utility Model Application No. 51-51038 and Utility Model Application No. 57-11081
As seen in the issue, by a single appearance mechanism,
Some devices have appeared that have separate cursive characters, but all of these devices are complicated to assemble or operate, are not easy to use, and lack rationality. .
本案は、従来技術にみられるこのような欠点を
解消しようとするものであつて、一つの摺動部材
を軸心方向の前後いずれかへ移動させることによ
つて、この摺動部材の両端面に圧接される二つの

するものである。 The present invention is an attempt to eliminate such drawbacks seen in the prior art, and by moving one sliding member either forward or backward in the axial direction, both end surfaces of this sliding member are moved. The writing body is exposed from the barrel opening by moving one of the two writing body holding members that are in pressure contact with the writing body.Maintaining this writing state and releasing it is done by moving the elastic piece attached to the writing body holding member. The purpose is to provide a double-ended writing instrument that is highly convenient and convenient, which is not seen in the prior art, by engaging and disengaging the protrusion and two locking holes provided in the barrel.
以下、本案の実施例を図面に基づいて説明す
る。 Hereinafter, embodiments of the present invention will be described based on the drawings.
摺動部材1は軸筒Bに穿設した長孔2からその
把持部Hを突出して軸筒B内に移動可能に収容し
てありまた、筆記体3a,3bをそれぞれ保持す
る筆記体保持部材4a,4bは、この摺動部材1
の両端面1a,1bにそれぞれ、コイルスプリン
グ5a,5bの弾発力によつて、圧接されてい
る。 The sliding member 1 is movably accommodated in the barrel B with its grip portion H protruding from a long hole 2 bored in the barrel B, and also includes a writing body holding member that holds the writing bodies 3a and 3b, respectively. 4a and 4b are this sliding member 1
are pressed against both end surfaces 1a and 1b of the coil springs 5a and 5b, respectively, by the elastic forces of coil springs 5a and 5b.
6a,6bは筆記体保持部材4a,4bにそれ
ぞれ取付けた軸筒の半径方向へ弾発する弾発片で
あつて、その先部には突起部7a,7bが設けて
あり、この突起部7a,7bが軸筒Bに穿設した
内方係止孔8a,8bにそれぞれ係合して筆記体
保持部材4a,4bを軸筒B内の所定位置に収容
維持している。なお、弾発片6a,6bの突起部
7a,7bは軸筒B内での筆記体保持部材4a,
4bのよりスムーズな移動と、より確実な係止状
態の実現のために内方係止孔8a,8bの外方壁
と接する部分は緩勾配に形成しまた、その内方壁
に接する部分は急勾配に形成しておくとよい。 Reference numerals 6a and 6b are elastic pieces that spring in the radial direction of the barrels attached to the writing holding members 4a and 4b, respectively, and projections 7a and 7b are provided at the tips of the elastic pieces. 7b engages with inner locking holes 8a, 8b formed in the barrel B, respectively, to house and maintain the writing holding members 4a, 4b at predetermined positions in the barrel B. Note that the protrusions 7a and 7b of the elastic pieces 6a and 6b are the cursive holding members 4a and 7b in the barrel B, respectively.
In order to realize smoother movement of the locking hole 4b and a more reliable locking state, the portions of the inner locking holes 8a, 8b that contact the outer wall are formed with a gentle slope, and the portions that contact the inner wall are formed with a gentle slope. It is best to form it on a steep slope.
9a,9bは軸筒Bに穿設した外方係止孔であ
つて、筆記体保持部材4a,4bが摺動部材1の
移動によつてコイルスプリング5a,5bの弾発
力に抗して、軸筒Bの外方へ移動したとき、弾発
片6a,6bの突起部7a,7bと係合して、筆
記体3a,3bの筆端部3a′,3b′が軸筒開口部
10a,10bから露出した状態(筆記状態)を
維持するものである。 Reference numerals 9a and 9b are external locking holes drilled in the barrel B, through which the writing holding members 4a and 4b resist the elastic force of the coil springs 5a and 5b due to the movement of the sliding member 1. , when moving outward of the barrel B, engages with the protrusions 7a, 7b of the elastic pieces 6a, 6b, and the brush ends 3a', 3b' of the writing bodies 3a, 3b close to the barrel openings 10a, 3b. 10b is maintained in an exposed state (writing state).
軸筒B内に収容される別個の筆記体3a,3b
はそれぞれの保持部材4a,4bによつて着脱可
能に保持されるが、その保持構造は当該保持部材
4a,4bに設けた中空状の孔11a,11b内
に筆記体3a,3bの端部を圧入嵌着するなど適
宜なものであつてよい。 Separate cursive writing bodies 3a and 3b housed in barrel B
are removably held by the respective holding members 4a, 4b, and the holding structure is such that the ends of the writing bodies 3a, 3b are held in hollow holes 11a, 11b provided in the holding members 4a, 4b. It may be an appropriate method such as press-fitting.
本案においてはこの筆記体保持部材4a,4b
の孔11a,11bはそれぞれ、所定の偏心した
位置に設けてある(第2図、第3図参照)が、こ
のように両方の筆記体保持部材4a,4bの偏心
位置にそれぞれの孔11a,11bを設けておく
と嵌着した筆記体3a,3bはその端部で衝突す

心方向での寸法管理が容易になるという利点があ
る。12a,12bは軸筒開口部10a,10b
を形成する前後の口金部であつて、軸筒Bに着脱
自在に螺着してあり、その端部でコイルスプリン
グ5a,5bの弾発力を受けている。 In this proposal, these cursive holding members 4a, 4b
The holes 11a, 11b are respectively provided at predetermined eccentric positions (see FIGS. 2 and 3), and in this way, the holes 11a, 11b are provided at eccentric positions of both the writing holding members 4a, 4b. By providing 11b, the fitted writing bodies 3a and 3b can be accommodated in parallel without colliding at their ends, which has the advantage of facilitating dimensional control in the axial direction of the barrel B. 12a, 12b are shaft cylinder openings 10a, 10b
These are the front and rear mouth parts that form the base, and are removably screwed onto the shaft cylinder B, and receive the elastic force of the coil springs 5a and 5b at their ends.
いま、いずれか所望の筆記体を軸筒開口部から
露出させるには摺動部材1の把持部Hを持つその
軸心方向での前後いずれかへ摺動部材1を移動さ

やればよくこの結果、筆記体保持部材4aはコイ
ルスプリング5aの弾発力によつて再び、内方係
止孔8aにその弾発片の突起部7aを係合させて
元の状態に復することになる。 Now, in order to expose any desired writing body from the barrel opening, it is sufficient to move the sliding member 1 either forward or backward in the axial direction of the gripping portion H of the sliding member 1, for example, When exposing one of the writing bodies 3a, the sliding member 1 is moved so that the projection 7a of the resilient piece 6a of the writing body holding member 4a separates from the inner locking hole 8a and engages with the outer locking hole 9a. It is sufficient to move the coil spring 5a forward in the axial direction, that is, in the direction of the front mouthpiece 12a, against the elastic force of the coil spring 5a, until they are aligned. Moreover, in order to release the writing state obtained in this way, the elastic piece 6a that engages with the outer locking hole 9a is
The protrusion 7a may be released from the outer locking hole 9a by pressing it with an appropriate means such as the tip of a finger.As a result, the writing holding member 4a is released by the elastic force of the coil spring 5a. Then, the protrusion 7a of the resilient piece is again engaged with the inner locking hole 8a to restore the original state.

の提供が可能になつた。 As described above, the present invention moves one sliding member forward or backward in the axial direction of the sliding member, thereby moving the writing holding member that is in pressure contact with the end face of the sliding member on the moving side. The writing state obtained by this is maintained and released by the engagement and disengagement action between the protrusion of the elastic piece attached to the writing body holding member and the locking hole provided in the barrel. Compared to conventional writing instruments of this type, it is easy to operate, has mechanical durability, and requires fewer component parts, making it easier to assemble. It has become possible to provide a double-ended writing instrument that is easy to assemble and use.
