Description

本発明は、空気圧、燃料ガス等を駆動源とするファスナーの打ち込み工具に使用されるとともに、打ち込み工具の射出口にファスナーを送る際に、ファスナーを送り方向に確実に送り、あるいはファスナーが送り方向と逆方向に移動するのを確実に阻止する連結ファスナーに関するものである。   INDUSTRIAL APPLICABILITY The present invention is used for a fastener driving tool that uses air pressure, fuel gas, or the like as a drive source, and when the fastener is sent to the injection port of the driving tool, the fastener is reliably fed in the feeding direction, or the fastener is fed in the feeding direction. It is related with the connection fastener which blocks | prevents reliably moving to a reverse direction.

一般に、連結ファスナーには金属ワイヤで連結するものと合成樹脂材で連結するものとがあるが、合成樹脂材で連結する連結ファスナーには、主に曲げシート連結方式と平シート連結方式の2つの方式のものが知られている。曲げシート連結方式の連結ファスナーは、帯状シート部の上下の両側縁からそれぞれ同じ向きに釘保持部を連続的に折り曲げ形成し、上下に対応する保持片にそれぞれファスナーを嵌合保持させて連結したものである。平シート連結方式の連結ファスナーは、細長の平シート状の連結帯にファスナーを保持する保持部と隣り合う保持部間を連結する幅狭の連結部とを交互に設けたもので、連結帯が複数枚の場合もあり、またファスナーの軸部に頭部とほぼ同径のガイドチューブを嵌合保持させて連結したものもある。ガイドチューブは打ち込み時に射出口内でファスナーが傾かないようにガイドするもので、通常はガイドチューブの上下に連結帯が配置されている。平シートタイプの連結ファスナーは、ほとんどが真直状に形成されている。   In general, there are two types of connecting fasteners, one connected by metal wire and one connected by synthetic resin material. There are two main types of connecting fasteners connected by synthetic resin material: a bent sheet connecting method and a flat sheet connecting method. A method is known. The connecting fastener of the bent sheet connecting method is formed by continuously bending the nail holding portions in the same direction from the upper and lower side edges of the belt-like sheet portion and connecting the fasteners to the holding pieces corresponding to the upper and lower portions. Is. A flat sheet connection type fastener is provided by alternately providing a holding part for holding a fastener and a narrow connecting part for connecting between adjacent holding parts to an elongated flat sheet-like connection band. There are cases where there are a plurality of pieces, and there is also a case where a guide tube having the same diameter as the head is fitted and held on the shaft portion of the fastener. The guide tube guides the fastener so that the fastener does not tilt in the injection port when driven, and usually connecting bands are arranged above and below the guide tube. Most flat sheet type connecting fasteners are formed in a straight shape.

ところで、近年、平シート連結方式の連結ファスナーに、各ファスナー保持部を連結する連結部をオフセット、つまり連結部を連結帯の長手方向の右又は左のいずれか一側に偏るように設けたものが開発されている(特許文献1〜3参照)。これによれば、合成樹脂製連結帯を使用した連結ファスナーもコイル状に巻き回すことができるとともに、コイル状に巻き回したときにその外径を小さくしやすいので、多数のファスナーを打ち込み工具のマガジン内に装填することができるというメリットがある。   By the way, in recent years, a flat sheet connecting type connecting fastener is provided so that the connecting parts for connecting the fastener holding parts are offset, that is, the connecting parts are biased to either the right or left side in the longitudinal direction of the connecting band. Has been developed (see Patent Documents 1 to 3). According to this, a connecting fastener using a synthetic resin connecting band can also be wound in a coil shape, and its outer diameter can be easily reduced when wound in a coil shape. There is an advantage that it can be loaded into the magazine.

ところで、上記特許文献1〜3に開示されている構成の連結ファスナーを打ち込む打ち込み工具には、連結ファスナーを収納したマガジンから打ち込み用ノーズ部の射出口にファスナーを順次供給するファスナーの送り機構が設けられている。この送り機構は、送り爪と逆止爪とから構成され、送り爪はファスナー送り方向に往復動し、往動時に連結ファスナーに係合して射出口側に送り、復動して後位のファスナーに係合する。これに対し、逆止爪は、送り爪が復動する時に連結ファスナーに係合して連結ファスナーが送り爪とともに送りと逆方向に移動するのを阻止する。   By the way, the driving tool for driving the connecting fastener having the configuration disclosed in Patent Documents 1 to 3 is provided with a fastener feeding mechanism for sequentially supplying the fastener from the magazine storing the connecting fastener to the injection port of the driving nose portion. It has been. This feed mechanism is composed of a feed claw and a check claw, and the feed claw reciprocates in the fastener feed direction, engages with the connecting fastener at the time of forward movement, feeds it to the injection port side, moves backward, and moves backward. Engage with the fastener. On the other hand, the check claw engages with the connecting fastener when the feed claw moves backward to prevent the connecting fastener from moving in the direction opposite to the feed with the feed claw.

ところで、通常の平シート連結方式の連結ファスナーを使用する打ち込み工具では、上下に配された連結帯の間に送り爪又は逆止爪を移動させ、その先端をガイドチューブ又はファスナーの軸に係合させるように構成されている。   By the way, in a driving tool using a normal flat sheet connection type connecting fastener, the feed claw or the check claw is moved between the upper and lower connecting bands, and the tip is engaged with the shaft of the guide tube or the fastener. It is configured to let you.

特開2009−115212公報JP 2009-115212 A 特開2009−115213公報JP 2009-115213 A 特開2009−264585公報JP 2009-264585 A

しかしながら、送り爪又は逆止爪をガイドチューブ又はファスナーの軸に係合させる構造では、上記爪は連結帯の外側から内側に深く入って係合することになるので、大きく揺動させる必要がある。したがって、必然的にファスナーの送り機構が大きくならざるを得ない。また、特に逆止爪の場合は、連結ファスナーが後退しないように保持するだけであるから、わざわざファスナーの軸に係合させる必要はない。   However, in the structure in which the feed claw or the check claw is engaged with the shaft of the guide tube or the fastener, the claw enters the inside from the outside of the connecting band and engages with it, so it is necessary to swing it greatly. . Therefore, the fastener feeding mechanism is inevitably large. In particular, in the case of a check claw, it is only necessary to hold the connecting fastener so as not to retreat, so that it is not necessary to bother engaging with the fastener shaft.

そのため、連結帯に逆止爪を係合させることが考えられる。例えば上記特許文献1の図2に示される連結釘を送り機構で送る場合に、連結帯の連結部側の外縁部において釘保持部と連結部との境界部が、円弧部分と直線部分との境界に一定の角度を有する凹みが形成されているので、ここに逆止爪を係合させることが考えられる。しかし、この凹みはもともと係合部として形成されたものではないから、角度が浅く、緩やか過ぎて逆止爪が滑ってしまうおそれがあり、係合部としてはほとんど機能しない。そして、上記特許文献1の図11〜図13に示される連結帯は、形状は異なるが、逆止爪が係合する部分が2箇所あることから、逆止爪がそのいずれか又は両方に係合する可能性があり、係合が安定しないという問題がある。   Therefore, it is conceivable to engage the check claw with the connecting band. For example, when the connecting nail shown in FIG. 2 of Patent Document 1 is fed by a feeding mechanism, the boundary between the nail holding part and the connecting part at the outer edge part on the connecting part side of the connecting band is an arc part and a straight part. Since the dent which has a fixed angle is formed in the boundary, it is possible to engage a check claw here. However, since this dent is not originally formed as an engaging portion, the angle is shallow and there is a possibility that the check pawl may slip due to being too gentle, and the engaging portion hardly functions. And although the connection belt | band | zone shown by FIGS. 11-13 of the said patent document 1 differs in a shape, since the part which a check nail engages has two places, a check nail is related to either or both. There is a problem that the engagement is not stable.

また、特許文献2の連結帯の場合は、釘保持部に凸部が形成されている。この凸部は線対称に形成された2つの連結帯を中心線で切断したときにできた残余部であるが、これを利用して逆止爪を係合させようとしても、逆止爪は必ずしも凸部にのみ係合するわけではなく、特許文献1と同様に、頻度は少ないが、釘保持部と連結部との境界部の凹みに係合する場合もあり、逆止爪が2箇所で係合する可能性があり、係合が安定しない。   Moreover, in the case of the connection belt | band | zone of patent document 2, the convex part is formed in the nail holding | maintenance part. This convex part is a residual part formed when two connecting bands formed in line symmetry are cut at the center line, but even if it tries to engage the check claw using this, the check claw is It does not necessarily engage only with the convex part, but, as in Patent Document 1, the frequency is low, but it may engage with a recess at the boundary between the nail holding part and the connecting part, and there are two check claws. The engagement may not be stable.

さらに、特許文献3の連結帯は平シートタイプではないが、この場合も、特許文献2の場合と同様に、逆止爪は互いに形状が異なる2箇所の部位に係合する可能性があり、係合が安定しない。   Furthermore, although the connection band of Patent Document 3 is not a flat sheet type, in this case as well, as in Patent Document 2, there is a possibility that the check pawls engage with two parts having different shapes, Engagement is not stable.

送り爪を連結帯の同じ部位に係合させる場合も、同様の問題が発生する。   A similar problem occurs when the feed claw is engaged with the same part of the connecting band.

このように、いずれの場合も、従来の連結帯の形状をそのままにして送り又は逆止に利用しようとしても、そもそも上記部位は逆止爪や送り爪を係合させる目的で形成されたものではないので、上記部位に爪を係合させようとしても、送り又は逆止が安定しないのはむしろ当然である。   As described above, in any case, even if an attempt is made to use the conventional connecting band as it is for feeding or check, the part is not originally formed for the purpose of engaging the check claw or the feed claw. Therefore, even if it is intended to engage the claw with the part, it is natural that the feeding or check is not stable.

本発明は上記問題点を解消し、合成樹脂製の連結帯を確実に送り方向に送り又は逆方向への移動を阻止することができる連結ファスナーを提供することをその課題とする。   An object of the present invention is to solve the above-mentioned problems and to provide a connecting fastener that can reliably feed a connecting band made of synthetic resin in the feeding direction or prevent movement in the reverse direction.

Two belt-like flat sheets are arranged on the upper and lower sides, the connecting part is provided on either side of the connecting band at the left or right side, and the outer edge on the connecting part side in the longitudinal direction of the connecting band is substantially A straight portion is formed along the outer edge portion with a predetermined interval, and an engagement portion is formed at a predetermined interval, and the connecting portion is formed narrow so that a recess is formed between the fastener holding portions on the opposite side of the engagement portion. And the engagement portion is provided in the vertical direction so as to correspond to the two connection bands, and the width direction of the connection band between the shaft center line of the shaft hole and the bottom of the engagement recess The shortest distance at is set to 0.5 mm or more. And features.

請求項に係る発明は、連結帯の長辺部の両側に、ファスナーを保持する軸孔を有するファスナー保持部を間隔をおいて形成した連結ファスナーにおいて、上記連結帯を細長の曲げシートで形成し、上記連結帯とファスナー保持部とを側面視において略コの字形、U字形、又はV字形に形成するとともに、上記連結帯の外面に係合凹部を上下方向に通しで設けたことを特徴とする。 According to a fifth aspect of the present invention, there is provided a connection fastener in which fastener holding portions having shaft holes for holding fasteners are formed on both sides of the long side portion of the connection band at intervals, and the connection band is formed of an elongated bent sheet. and, wherein the substantially U-shaped, so as to form a U-shape, or V-shaped, provided with engaging recesses in through vertically on the outer surface of the connecting band in the side view and the connecting band and the fastener holding portion And

請求項に係る発明は、請求項において、上記連結帯に、係合凹部を上下方向に通しで設けることに代えて、係合凸部を上下両側設けたことを特徴とする。 According to a sixth aspect of the present invention, in the fifth aspect of the present invention, the engaging protrusions are provided on both the upper and lower sides in the connection band, instead of providing the engaging concave portions in the vertical direction.

請求項1、2又は3に係る発明によれば、ファスナー保持部の、連結帯の長手方向の連結部側に略真直に形成した外縁部に沿って所定の間隔をおいて同じ形状の係合部(係合凹部、係合凸部)を形成したので、ファスナー打ち込み工具側のファスナー送り機構の係合手段(逆止爪又は送り爪)に対する係合部位が1箇所となり、確実に所定の係合部に係合することができるので、送りや逆止が安定する。   According to the invention which concerns on Claim 1, 2, or 3, Engagement of the same shape at predetermined intervals along the outer edge part formed substantially straight on the connecting part side in the longitudinal direction of the connecting band of the fastener holding part Since the portion (engagement recess, engagement projection) is formed, there is only one engagement site for the engagement means (check claw or feed claw) of the fastener feeding mechanism on the fastener driving tool side, and a predetermined engagement is ensured. Since it can be engaged with the joint, feeding and check are stable.

請求項4に係る発明によれば、ファスナー保持部に形成されてファスナーを保持する軸孔の軸中心線と上記係合凹部の底部との間の連結帯の幅方向における最短距離を0.5mm以上に設定したことにより、上記ファスナー保持部の軸孔と係合凹部間に連結帯が破断しない十分な幅を残すことができ、強度上の問題がなく安定した連結帯を得ることができる。   According to the invention of claim 4, the shortest distance in the width direction of the connecting band between the shaft center line of the shaft hole formed in the fastener holding portion and holding the fastener and the bottom portion of the engagement recess is 0.5 mm. By setting as described above, it is possible to leave a sufficient width between the shaft hole of the fastener holding portion and the engagement recess so that the connection band is not broken, and it is possible to obtain a stable connection band without a problem in strength.

また、上記連結部の外縁部に沿って所定の間隔をおいて係合部を上下方向に通しで設けたので、ファスナー打ち込み工具側の送り機構の係合手段が係合部以外の外縁部に係合することはなく、確実に係合部にのみ係合することができ、ファスナーの送りや逆止が安定する。 Further , since the engaging portion is provided in the vertical direction at a predetermined interval along the outer edge portion of the connecting portion, the engaging means of the feed mechanism on the fastener driving tool side is provided on the outer edge portion other than the engaging portion. It can be engaged only with the engaging portion without being engaged, and the feed and check of the fastener are stabilized.

また、係合部は上下方向に通しで設けられているので、係合部の領域が大きくなり、このため、多少連結釘の連結帯の上下位置がずれても、上記係合手段が確実に係合部に係合して逆止又は送りが確保されるから、連結帯の位置精度をラフにでき、送り不良がなくなり、信頼性・安全性が向上する。   In addition, since the engaging portion is provided in the vertical direction, the area of the engaging portion becomes large. Therefore, even if the vertical position of the connecting band of the connecting nail is slightly shifted, the engaging means is ensured. Since non-return or feeding is ensured by engaging with the engaging portion, the positional accuracy of the connecting band can be roughened, feeding failure is eliminated, and reliability and safety are improved.

請求項に係る発明によれば、係合凹部は連結帯に上下方向に通しで設けられているので、多少連結釘の連結帯の上下位置がずれても、ファスナー打ち込み工具側の係合手段が確実に係合凹部に係合して逆止又は送りが確保されるから、連結帯の位置精度をラフにでき、送り不良がなくなり、信頼性・安全性が向上する。このように、係合凹部は上下間の領域を全て係合面として利用できるため、係合時の安定性が向上する。 According to the fifth aspect of the present invention, since the engaging recess is provided through the connecting band in the vertical direction, the engaging means on the fastener driving tool side even if the vertical position of the connecting band of the connecting nail is somewhat shifted. Since the non-return or feed is ensured by reliably engaging the engaging recess, the position accuracy of the connecting band can be roughened, feed failure is eliminated, and reliability and safety are improved. In this way, since the engaging recess can use the entire area between the upper and lower sides as the engaging surface, the stability during engagement is improved.

請求項に係る発明によれば、係合凸部は連結帯の上下両側設けられ、上下方向に通しで設ける必要がないので、帯状の平シートを切り起し加工することなどにより、簡単に形成することができる。また、切起こしによって係合凸部を形成する場合、切起し以外の部分によって強度が保持される。 According to the invention of claim 6 , the engaging convex portions are provided on both the upper and lower sides of the connecting band and do not need to be provided through in the vertical direction, so it is easy to cut and process the belt-like flat sheet. Can be formed. Moreover, when forming an engagement convex part by cutting and raising, intensity | strength is hold | maintained by parts other than cutting and raising.

以下に、本発明の実施形態の一部を図1〜3に基づいて説明する。   Below, a part of embodiment of this invention is described based on FIGS.

図1(a)(b)は、それぞれ連結ファスナーの実施形態としての連結釘の一部の正面図及び斜視図であり、図2は連結帯の一部の平面図である。連結釘Aは、複数の釘1の軸部1aに筒状のガイドチューブ(ガイド部材)2を嵌挿するとともに、これらの釘1を合成樹脂製の上下2枚の連結帯3を介して連結したものである。連結帯3はガイドチューブ2を上下から挟むように配置されている。   1A and 1B are a front view and a perspective view of a part of a connecting nail as an embodiment of a connecting fastener, respectively, and FIG. 2 is a plan view of a part of a connecting band. In the connecting nail A, a cylindrical guide tube (guide member) 2 is inserted into the shaft portion 1a of a plurality of nails 1 and these nails 1 are connected via two upper and lower connecting bands 3 made of synthetic resin. It is a thing. The connecting band 3 is arranged so as to sandwich the guide tube 2 from above and below.

ガイドチューブ2はポリプロピレン、ポリエチレン等の合成樹脂製又はアルミニウム等の金属製の短筒状部材で、その外径は釘1の頭部1bの径とほぼ同じかそれよりもやや小さい程度に形成され、後述の図17に示される釘打機の先端に設けられた射出用ノーズ部4の射出口5の内径よりも僅かに小さい程度に設定されている。これにより、釘1は、釘打機等の射出用ノーズ部4に到達してドライバ6により打ち込まれる際、釘1の姿勢はガイドチューブ2によって打ち込み方向に正しくガイドされる。   The guide tube 2 is a short cylindrical member made of a synthetic resin such as polypropylene or polyethylene or a metal such as aluminum, and has an outer diameter that is substantially the same as or slightly smaller than the diameter of the head 1b of the nail 1. This is set to be slightly smaller than the inner diameter of the injection port 5 of the injection nose portion 4 provided at the tip of the nailing machine shown in FIG. Thus, when the nail 1 reaches the injection nose portion 4 such as a nail driver and is driven by the driver 6, the nail 1 is correctly guided in the driving direction by the guide tube 2.

連結帯3は、合成樹脂製の細長帯状の平シートによって構成され、ガイドチューブ2の中心孔と同じ程度の大きさの軸孔7が形成された釘保持部8(ファスナー保持部)と、隣り合う釘保持部8を連結する幅狭の連結部9とを交互に連続して形成したものである。連結部9は連結帯3の中央よりも左右(図2では上方)の一方の片寄り側、つまり連結釘Aを後述の釘打機に装填したときに図18(a)に示す逆止爪30が配置されている側に形成されている。このため、連結帯の連結部9側の外縁部3aは略真直に、他側は釘保持部8間によって凹部10が形成された形状となっている。そして、外縁部3aの各釘保持部8には、後述の図18に示す逆止爪30が係合する逆止用の係合部として係合凹部11aが切欠き形成されている。係合凹部11aはほぼ三角形状で、その一端11pは連結帯3の長手方向に対して略直角に、他端側11qは斜めに形成されている。しかし、係合凹部11はこの形状に限定されない。凹字状、V字状、台形状等であってもよい。連結釘Aを釘1の頭部側から見たとき、ガイドチューブ2が上下の係合凹部11aの領域に大きくはみ出さない形状になっている。   The connecting band 3 is composed of a long strip-shaped flat sheet made of synthetic resin, and is adjacent to a nail holding part 8 (fastener holding part) in which a shaft hole 7 having the same size as the center hole of the guide tube 2 is formed. Narrow connection portions 9 for connecting the matching nail holding portions 8 are alternately and continuously formed. The connecting portion 9 is one of the left and right sides (upward in FIG. 2) from the center of the connecting band 3, that is, when the connecting nail A is loaded into a nailing machine described later, a check claw shown in FIG. It is formed on the side where 30 is arranged. For this reason, the outer edge portion 3a on the connecting portion 9 side of the connecting band is substantially straight, and the other side has a shape in which a recess 10 is formed between the nail holding portions 8. Each nail holding portion 8 of the outer edge portion 3a is notched with an engaging recess 11a as a non-return engaging portion with which a non-return claw 30 shown in FIG. The engaging recess 11a has a substantially triangular shape, and one end 11p thereof is formed substantially perpendicular to the longitudinal direction of the connecting band 3 and the other end 11q is formed obliquely. However, the engagement recess 11 is not limited to this shape. It may be concave, V-shaped, trapezoidal or the like. When the connecting nail A is viewed from the head side of the nail 1, the guide tube 2 has a shape that does not protrude greatly into the region of the upper and lower engaging recesses 11a.

上記連結釘Aによれば、連結帯3の外縁部3aが略真直に形成されているので、後述のように、釘打機の送り機構の送り爪が係合凹部以外の外縁部3aに係合することはなく、確実に係合凹部11aにのみ係合することができるので、送りや逆止が安定する。また、連結部9はその両端部9a、9bも含めて連結帯3の中央より一方の片寄り側に設けられているので、釘打機に装填したとき、連結釘Aの片寄り側の外縁部3aは送り通路の一側に当接するので、送り時に連結釘が左右に振れにくく、安定的に送ることができるとともに、後述に示す逆止爪又は送り爪を確実に係合させることができる。   According to the connecting nail A, since the outer edge portion 3a of the connecting band 3 is formed substantially straight, as will be described later, the feeding claw of the feeding mechanism of the nail driver is engaged with the outer edge portion 3a other than the engaging recess. Since it can be engaged with only the engaging recess 11a without fail, feeding and check are stable. Further, since the connecting portion 9 is provided on one side of the connecting band 3 including both end portions 9a and 9b, the outer edge of the connecting nail A on the side of the connecting nail A when loaded into the nail driver. Since the portion 3a abuts on one side of the feed passage, the connecting nail is less likely to swing left and right at the time of feeding, and can be stably fed, and a check pawl or feed pawl described later can be reliably engaged. .

ところで、釘保持部8には係合凹部11aによる裂け目が形成されるので、係合凹部11aの深さには限界がある。図3に示されるように、ポリプロピレンまたはポリエチレン製の連結帯3の肉厚が1mm、釘保持部8の直径が8mmで、軸孔7の直径が3.7mmの場合、釘保持部8の連結部9側と軸孔7側に、それぞれ最低でも同じ1mmの幅寸法(w1、w2)を残さないと、十分な連結強度が得られず、釘送りの途中、打ち込み時、あるいは輸送時などに発生する衝撃によって破断してしまう可能性が高い。また、連結帯3の引っ張り強度として3kgf以上が必要である。この強度を確保するためには、上記軸孔7の軸中心線(連結帯の長手方向に沿って軸中心Oを通る直線)Lと係合凹部11aの底部11cとの間にボリュームSが必要である。このボリュームSを確保するためには、軸孔7の軸中心線Lと係合凹部11aの底部11cとの間の距離aがどれくらい必要かを実験したところ、図4(a)(b)に示されるように、上記距離aは0.5mm以上に設定する必要があることが判明した。もちろん、肉厚が異なれば、上記の寸法w1(w2)、aの数値も変わってくるが、上記の条件に照らし、例えば断面積が同じになるように変更すればよい。   By the way, since the nail | claw holding | maintenance part 8 is formed with the tear by the engagement recessed part 11a, the depth of the engagement recessed part 11a has a limit. As shown in FIG. 3, when the thickness of the connection band 3 made of polypropylene or polyethylene is 1 mm, the diameter of the nail holding part 8 is 8 mm, and the diameter of the shaft hole 7 is 3.7 mm, the connection of the nail holding part 8 is performed. If the same width (w1, w2) of at least 1 mm is not left on the part 9 side and the shaft hole 7 side, sufficient connection strength cannot be obtained, and during nail feeding, driving, or transportation There is a high possibility of breakage due to the generated impact. Further, the tensile strength of the connecting band 3 is required to be 3 kgf or more. In order to ensure this strength, a volume S is required between the axial center line (straight line passing through the axial center O along the longitudinal direction of the connecting band) L and the bottom 11c of the engaging recess 11a. It is. In order to secure the volume S, an experiment was conducted to determine how much distance a between the shaft center line L of the shaft hole 7 and the bottom portion 11c of the engaging recess 11a is necessary, as shown in FIGS. 4 (a) and 4 (b). As shown, it has been found that the distance a needs to be set to 0.5 mm or more. Of course, if the thickness is different, the numerical values of the dimensions w1 (w2) and a also change. However, in light of the above conditions, for example, the cross-sectional areas may be changed to be the same.

連結帯3に釘1を連結するときは、連結帯3の軸孔7をガイドチューブ2の中心孔と整合させて並べ、これらの孔に釘1の軸部1を圧入すればよい。これにより、各釘1は連結帯3によって連結される。連結釘Aは渦巻状に巻くことができるように構成されている。   When the nail 1 is connected to the connecting band 3, the shaft hole 7 of the connecting band 3 is aligned with the central hole of the guide tube 2, and the shaft portion 1 of the nail 1 may be press-fitted into these holes. Thereby, each nail 1 is connected by the connection band 3. The connecting nail A is configured to be wound in a spiral shape.

なお、連結帯の材料はポリプロピレン、ポリエチレン等の合成樹脂のほか、紙でもよい。紙には植物繊維その他の繊維を膠着させて製造したものに限らず、合成紙、複合紙、ラミネート紙等が含まれる。   The connecting band material may be paper, as well as synthetic resin such as polypropylene and polyethylene. The paper is not limited to those produced by glueing vegetable fibers or other fibers, but includes synthetic paper, composite paper, laminated paper, and the like.

また、連結帯3の外縁部3aは略真直に、すなわち、真直か、あるいは波形などのように、後述の逆止爪30が当たっても係合しない程度に全長にわたって滑らかに形成されていればよい。後述の他の連結帯についても同様である。   Further, the outer edge portion 3a of the connecting band 3 is substantially straight, that is, straight or corrugated or the like so long as it is smoothly formed over the entire length to the extent that it does not engage even if a later-described check claw 30 hits. Good. The same applies to other connecting bands described later.

(釘打機)
次に、上記構成の連結釘Aはコイル状に巻き回され、図17に示されるような釘打機Bのマガジン12に装填されて使用される。すなわち、釘打機本体13にはシリンダ14と打撃ピストン15とが設けられ、ピストン15にはドライバ6が一体に結合されている。釘打機本体13の下部にはノーズ部4が設けられ、ノーズ部4には釘の射出口5が形成されている。また、ノーズ部4の後方にはマガジン12が設けられ、射出口5とマガジン12との間には釘通路16が形成されている。マガジン12内に装填された連結釘Aは図18に示されるように、釘通路16を通って射出口5内に供給される。釘打ち込みにあたり、トリガ17を引き操作すると、起動バルブ18が作動するとともに、メインバルブ19が圧縮空気が貯留されたエアチャンバ20をシリンダ14に開くので、シリンダ14に急激に送り込まれた圧縮空気により。ピストン15とともにドライバ6が駆動され、射出口5内の釘を打撃して打ち出すように構成されている。
(Nailer)
Next, the connecting nail A having the above-described configuration is wound in a coil shape, and is loaded into a magazine 12 of a nailing machine B as shown in FIG. That is, the nailing machine main body 13 is provided with a cylinder 14 and a striking piston 15, and the driver 6 is integrally coupled to the piston 15. A nose portion 4 is provided in the lower portion of the nailing machine body 13, and a nail injection port 5 is formed in the nose portion 4. Further, a magazine 12 is provided behind the nose portion 4, and a nail passage 16 is formed between the injection port 5 and the magazine 12. The connecting nail A loaded in the magazine 12 is supplied into the injection port 5 through the nail passage 16 as shown in FIG. When the trigger 17 is pulled when the nail is driven, the start valve 18 is activated, and the main valve 19 opens the air chamber 20 in which the compressed air is stored in the cylinder 14, so that the compressed air suddenly fed into the cylinder 14 . The driver 6 is driven together with the piston 15 so that the nail in the injection port 5 is struck and driven out.

ところで、釘通路16は図18(a)に示されるように、固定壁21と開閉ドア22との間に形成されているが、この釘通路16には連結釘Aを射出口5内に送り出す釘送り機構27が設けられている。すなわち、固定壁21の外側には釘送りシリンダ23が配置され、釘送りシリンダ23には送りピストン24が前後に往復動自在に配置されている。送りピストン24には前方に突出する送りロッド25が一体に設けられ、送りロッド25の先端には送り爪26が回動可能に取り付けられている。送り爪26は回動により、固定壁21に形成された開口部(図示せず)から釘通路16内に出没するように構成されている。送りピストン24はバネ28によって前方に付勢され、所定のタイミングでエア管路29から釘送りシリンダ23内に圧縮空気が送られることにより送りピストン24が後退し、上記圧縮空気が排出されることにより、送りピストン24はバネ28によって前進するようになっている。   By the way, the nail passage 16 is formed between the fixed wall 21 and the open / close door 22 as shown in FIG. 18A, and the connecting nail A is fed into the injection port 5 in the nail passage 16. A nail feed mechanism 27 is provided. That is, a nail feed cylinder 23 is disposed outside the fixed wall 21, and a feed piston 24 is disposed in the nail feed cylinder 23 so as to be capable of reciprocating back and forth. The feed piston 24 is integrally provided with a feed rod 25 protruding forward, and a feed claw 26 is rotatably attached to the tip of the feed rod 25. The feed claw 26 is configured so as to appear and disappear in the nail passage 16 from an opening (not shown) formed in the fixed wall 21 by rotation. The feed piston 24 is urged forward by a spring 28, and the feed piston 24 moves backward by discharging compressed air from the air pipe 29 into the nail feed cylinder 23 at a predetermined timing, and the compressed air is discharged. Thus, the feed piston 24 is moved forward by the spring 28.

これに対し、ドア22は釘通路16を開閉するもので、その内側には逆止爪30が設けられている。ドア22は、図19(a)(b)及び図20に示されるように、ノーズ部4に沿って設けられた回動軸31に回動自在に設けられている。ドア22は箱形のドア本体32の開口部を表面板33でカバーしたもので、ドア本体32の上板34と下板35との間には支軸36が設けられ、支軸36には逆止爪部材37が回動自在に取り付けられている。逆止爪部材37は板状の部材で、その中間部から前端部には逆止爪30が形成され、図20に示されるように、後部は二股に分岐されている。逆止爪部材37の前部はZ字形に形成され、逆止爪30の先端30aはさらに少し釘通路16側に屈曲形成されている。逆止爪30も上下に分かれているが、上下一体に形成してもよい。また、逆止爪部材37の後部の上部40と下部41には上下に対向する支持片42が折り曲げ形成され、支持片42は上記支軸36に回動自在に嵌合している。なお、支軸36にはねじりコイルバネ43が巻きつけられ、その一端43aはドア22の表面板33(図22参照)の背面に係合し、他端43bは逆止爪部材37の中間部に係合している。これにより、逆止爪部材37は常時釘通路16の中心側に付勢され、連結釘Aを中心側に押圧している。   On the other hand, the door 22 opens and closes the nail passage 16, and a check claw 30 is provided inside thereof. As shown in FIGS. 19A, 19 </ b> B, and 20, the door 22 is rotatably provided on a rotation shaft 31 provided along the nose portion 4. The door 22 has an opening of a box-shaped door body 32 covered with a surface plate 33, and a support shaft 36 is provided between an upper plate 34 and a lower plate 35 of the door body 32. A check claw member 37 is rotatably attached. The check claw member 37 is a plate-like member, and a check claw 30 is formed from an intermediate portion to a front end portion thereof, and the rear portion is bifurcated as shown in FIG. The front portion of the check claw member 37 is formed in a Z shape, and the tip 30a of the check claw 30 is further bent toward the nail passage 16 side. The check claw 30 is also divided into upper and lower parts, but may be formed integrally with the upper and lower parts. Further, a support piece 42 that is vertically opposed is formed on the upper portion 40 and the lower portion 41 of the rear portion of the check claw member 37, and the support piece 42 is rotatably fitted to the support shaft 36. A torsion coil spring 43 is wound around the support shaft 36, one end 43 a is engaged with the back surface of the surface plate 33 (see FIG. 22) of the door 22, and the other end 43 b is in the middle portion of the check claw member 37. Is engaged. Thereby, the check claw member 37 is always urged toward the center side of the nail passage 16 and presses the connecting nail A toward the center side.

次に、上記構成の連結釘Aがマガジン12に装填された後、釘送り機構27が作動すると、送りピストン24はいったん図18(b)に示すように後退した後、同図(c)(d)のように前進する。前進したとき、送り爪26が連結釘Aの上下の連結帯3の送り側の凹部10に係合し、連結釘Aを前方に送り出し、同図(d)のように先頭の釘1を射出口5内に供給する。その後、上記釘1が同図(a)のように打ち出された後、送りピストン24は同図(b)のように再び後退するが、これに伴い、連結釘Aを逆方向に移動しようとすると、図21に示されるように、逆止爪30が連結帯3の係合凹部11aの一端11pに係合するので、連結釘Aは逆方向に移動することができずに同じ位置にとどまる。このため、送り爪26は回動して連結帯3から外れて確実に図18(c)の位置に後退する。なお、送りピストン24が前進するときは、逆止爪30は係合凹部11aに係合することはできないので、係合が外れるように回動し、連結釘Aは前方に送られる。また、図21に示されるように、逆止爪30の先端30aに続く面状部30bは連結帯3の外縁部3aに当接する。このように、逆止爪30と連結帯3とが長く接触し、接触面積も大きいので、逆止爪30が係合凹部11aに係合したときに、連結帯3は先端30aとの係合部と係合凹部11aの先端11pとの係合部を中心に回動しにくいので、係合が外れるのが良好に抑えられ、連結帯3の姿勢を正しく制御して逆方向に移動するのを確実に防止することができる。   Next, when the nail feed mechanism 27 is actuated after the connecting nail A having the above structure is loaded in the magazine 12, the feed piston 24 once retracts as shown in FIG. Move forward as in d). When moving forward, the feed claw 26 engages with the recess 10 on the feed side of the upper and lower connection bands 3 of the connection nail A, feeds the connection nail A forward, and shoots the top nail 1 as shown in FIG. Feed into outlet 5. After that, after the nail 1 is driven out as shown in FIG. 5A, the feed piston 24 moves back again as shown in FIG. 5B, and accordingly, the connecting nail A tries to move in the reverse direction. Then, as shown in FIG. 21, since the check claw 30 engages with the one end 11p of the engagement recess 11a of the connection band 3, the connection nail A cannot move in the reverse direction and remains in the same position. . For this reason, the feed claw 26 is rotated and detached from the connecting band 3 and reliably retracts to the position shown in FIG. When the feed piston 24 moves forward, the check pawl 30 cannot be engaged with the engagement recess 11a, so that it rotates so as to be disengaged, and the connecting nail A is fed forward. Further, as shown in FIG. 21, the planar portion 30 b following the tip 30 a of the check claw 30 abuts on the outer edge portion 3 a of the connection band 3. Thus, since the check claw 30 and the connection band 3 are in contact with each other for a long time and the contact area is large, the connection band 3 is engaged with the tip 30a when the check claw 30 is engaged with the engagement recess 11a. Since it is difficult to rotate around the engaging portion between the engaging portion and the tip 11p of the engaging recess 11a, it is possible to suppress the disengagement well and to move the connecting band 3 in the opposite direction by correctly controlling the posture of the connecting band 3. Can be reliably prevented.

なお、係合凹部11aは、図1(a)(b)に示されるように、上下の連結帯3に上下方向に通しで設けられている。そして、上記釘送り機構の逆止爪30が上述のように連結帯3の係合凹部11aに係合する場合、図22(a)及び図23(a)に示されるように、連結帯3の位置が逆止爪30の幅w内にあるときは、逆止爪30は確実に係合凹部11aに係合することができる。換言すれば、上記幅寸法の範囲内で連結帯3がずれても逆止爪30は係合凹部11aに係合する。しかも、2枚の連結帯3のうち一方の係合凹部11aに係合できなくても他方の係合凹部11aに係合することができる。   In addition, as shown in FIGS. 1A and 1B, the engaging recess 11a is provided through the upper and lower connecting bands 3 in the vertical direction. When the check claw 30 of the nail feeding mechanism engages with the engaging recess 11a of the connection band 3 as described above, as shown in FIGS. 22 (a) and 23 (a), the connection band 3 When the position is within the width w of the check claw 30, the check claw 30 can be reliably engaged with the engagement recess 11a. In other words, even if the connecting band 3 is displaced within the width dimension, the check pawl 30 engages with the engaging recess 11a. And even if it cannot engage with one engaging recessed part 11a among the two connection bands 3, it can engage with the other engaging recessed part 11a.

このように、逆止爪30は従来のように上下の連結釘の連結帯3間に挿入する必要がない。逆止爪30は板状であり、多少連結釘の連結帯3の上下位置がずれても、連結帯3の外縁部3aを押圧していれば、確実に係合凹部11aに係合して逆止が機能するから、釘1の位置がほぼ正確に出るので、連結帯3の上下方向の位置ずれによる送り不良がなくなり、信頼性・安全性が向上する。   Thus, the check pawl 30 does not need to be inserted between the upper and lower connection nails of the connection band 3 as in the prior art. The check claw 30 has a plate shape, and even if the vertical position of the connection band 3 of the connection nail is slightly shifted, if the outer edge portion 3a of the connection band 3 is pressed, the check claw 30 is surely engaged with the engagement recess 11a. Since the check functions, the position of the nail 1 comes out almost accurately, so that there is no feed failure due to the vertical displacement of the connecting band 3 and the reliability and safety are improved.

同様に、逆止爪30の位置精度も要求されないから、ドア22は、逆止爪部材37を板金加工により、ドア本体32を合成樹脂によって構成することができ、部品コストを低く、しかもドア22全体を軽量化することができる。   Similarly, since the positional accuracy of the check pawl 30 is not required, the door 22 can be formed of the check pawl member 37 by sheet metal processing, and the door main body 32 can be made of synthetic resin. The whole can be reduced in weight.

(連結帯の他の実施形態)
ところで、上述の逆止用の係合部は、逆止爪8との関係で決定すればよく、上記係合凹部11aのように、連結帯3の内側に凹む形状に限定されない。係合凹部11aの位置も特に限定されない。係合部11が外側に向かって突出する構成であってもよい。また、2枚の平シート状連結帯を上下に間隔をおいて配置するのではなく、2枚の連結帯を重ねて配置し、係合凹部が上下方向(釘軸と略平行な方向)に連続するように形成してもよい。次に、このような連結釘のいくつかの形態について述べる。
(Other embodiments of connecting band)
By the way, the above-described engaging portion for the check may be determined based on the relationship with the check claw 8 and is not limited to a shape recessed inside the connecting band 3 as in the case of the engaging recess 11a. The position of the engaging recess 11a is not particularly limited. The structure which the engaging part 11 protrudes toward the outer side may be sufficient. In addition, two flat sheet-like connecting bands are not arranged at an interval in the vertical direction, but two connecting bands are arranged so as to overlap each other, and the engaging recesses are in the vertical direction (direction substantially parallel to the nail axis). You may form so that it may continue. Next, several forms of such a connecting nail will be described.

例えば、連結部9を、その両端部を含め、連結帯3の中央より左右のいずれか一方の片寄り側に設けたものについては、図5(a)に示される連結釘Aの係合凹部11aのように、釘保持部8の中央よりも後方位置に形成してもよく、同図(b)に示される連結釘Aの係合凹部11aのように釘保持部8の中央と同じ位置に形成してもよい。さらには、同図(c)の連結釘Aの係合凹部11aのように連結部9に形成してもよい。同図(d)(e)のように、連結釘Aの係合凹部11aのように、凹み形状を大きく形成してもよい。なお、同図(e)は同図(d)に釘保持部8よりも大きめのガイドチューブ2を配置した構成である。   For example, in the case where the connecting portion 9 is provided on either one of the left and right sides from the center of the connecting band 3 including its both ends, the engaging recess of the connecting nail A shown in FIG. 11a, it may be formed at a position rearward of the center of the nail holding portion 8, and the same position as the center of the nail holding portion 8 as in the engaging recess 11a of the connecting nail A shown in FIG. You may form in. Furthermore, you may form in the connection part 9 like the engagement recessed part 11a of the connection nail A of the same figure (c). As shown in FIGS. 4D and 4E, the concave shape may be formed larger like the engaging concave portion 11a of the connecting nail A. In addition, the figure (e) is the structure which has arrange | positioned the guide tube 2 larger than the nail holding | maintenance part 8 in the figure (d).

上述のように、いずれも連結帯3の長手方向の連結部側に略真直に形成した外縁部3aに沿った位置に係合凹部11aが設けられ、係合手段の逆止爪30に対する係合部位が1箇所となるので、逆止が安定する。   As described above, the engaging recess 11a is provided at a position along the outer edge portion 3a formed substantially straight on the connecting portion side in the longitudinal direction of the connecting band 3, and the engaging means engages with the check claw 30. Since there is only one part, the check is stable.

さらに、連結帯3は連結部両端部9a、9bも含めて連結帯中央より一方の片寄り側に設けた構成に限定されない。係合凹部11aが逆止爪が係合しない程度に滑らかであれば、図6のように、連結部9の一端は連結帯3の略中心に、他端はその一方の片寄り側に設ける構成としてもよい。   Further, the connection band 3 is not limited to the configuration provided on one side of the connection band including the both ends 9a and 9b of the connection part. If the engaging recess 11a is so smooth that the check pawl does not engage, as shown in FIG. 6, one end of the connecting portion 9 is provided substantially at the center of the connecting band 3, and the other end is provided on one side of the connecting band 9 as shown in FIG. It is good also as a structure.

また、連結帯3は1枚のみであってもよく、また肉薄のものに限定されない。例えば、図7及び図9(b)(c)の連結釘Aのように1枚の肉厚の連結帯3を用いてもよい。この場合も、係合凹部11aは上下方向に連続するように形成されている。   Moreover, the connection belt | band | zone 3 may be only 1 sheet, and is not limited to a thin thing. For example, one thick connecting band 3 may be used like the connecting nail A in FIGS. 7 and 9B and 9C. Also in this case, the engaging recess 11a is formed to be continuous in the vertical direction.

上記構成の連結釘Aによれば、連結帯3の係合凹部11a(又は係合凸部)は、釘1の軸孔7とともに同一平面となる連結帯3に加工すればよいので、寸法精度を出しやすい。   According to the connection nail A having the above-described configuration, the engagement recess 11a (or engagement protrusion) of the connection band 3 may be processed into the connection band 3 that is in the same plane together with the shaft hole 7 of the nail 1. It is easy to put out.

また、係合部は、図8(a)〜(e)の連結釘Aのように、連結帯3の連結部9側の外縁部3aに沿って所定の間隔をおいて外側に向かって突出する係合凸部11bとして形成してもよい。係合部11が凸状に形成されている場合は、釘打機の逆止爪は単なるZ字形の形状でよい。これらの係合凸部1bは、いずれも連結帯3の長手方向に沿って、釘保持部8の中央(同図(b)(e)の連結釘)、あるいは中央よりも釘の送り方向の前方側(同図(d)の連結釘)又は後方側(同図(a)(c)の連結釘)に形成されている。前述したように、連結帯に対する係合手段である逆止爪はそのア−ム部分(図21の面状部30b)が連結帯の外縁部3aに当接することによって、ア−ム部分が連結帯に当接する領域面積を大きくすることが可能であり、連結帯の回転を有効に防止することができるから、連結帯の姿勢制御が向上する。   Further, the engaging portion protrudes outward at a predetermined interval along the outer edge portion 3a of the connecting band 3 on the connecting portion 9 side, like the connecting nail A in FIGS. 8 (a) to 8 (e). You may form as the engaging convex part 11b to do. When the engaging portion 11 is formed in a convex shape, the check pawl of the nailing machine may be a simple Z-shape. These engaging projections 1b are arranged along the longitudinal direction of the connecting band 3 in the center of the nail holding part 8 (the connecting nail in FIGS. 5B and 5E), or in the nail feed direction from the center. It is formed on the front side (the connecting nail in FIG. 4D) or the rear side (the connecting nail in FIGS. 1A and 1C). As described above, the check claw, which is an engaging means for the connection band, has the arm portion (the planar portion 30b in FIG. 21) abuts the outer edge 3a of the connection band, so that the arm portion is connected. Since it is possible to increase the area of the area in contact with the band and to effectively prevent the rotation of the connecting band, the posture control of the connecting band is improved.

なお、図8(a)の連結釘Aの係合部11の一部は凹んでいるが、このような係合部は、外側に向かって突出する形状といってもよく、内側に凹む形状といってもよく、いずれか一方に限定する必要はない。   In addition, although a part of the engaging part 11 of the connecting nail A in FIG. 8A is recessed, such an engaging part may be said to be a shape that protrudes toward the outside, or a shape that is recessed toward the inside. It may be said that it is not necessary to limit to either one.

また、係合部を係合凸部として形成する場合も、連結帯の外縁部3aは略真直に形成されているのがよい。すなわち、真直か、あるいは波形などのように、逆止爪30が当たっても係合しない程度に全長にわたって滑らかに形成されていればよい。   Moreover, also when forming an engaging part as an engaging convex part, it is good for the outer edge part 3a of a connection belt to be formed substantially straight. That is, it may be formed straight or smooth so as not to engage even when the check pawl 30 hits, such as a waveform.

ところで、図1(a)(b)及び図7に示されるように、係合部11(係合凹部11a)は上下方向に通しで設けるのが好ましい。この構成によれば、上述のように、係合凹部11aは上下間の領域がそのまま係合手段の逆止爪に対する係合面積となるため、係合時の安定性が向上する。すなわち、係合凹部11aは釘の軸方向と平行に視たときに内側に凹むように形成されているので、係合可能な領域が大きくなるため、逆止爪を図23(a)の逆止爪30のように上下に長く形成することにより、係合凹部11aの上下間の領域に少しでも係合すれば逆止機能が発揮できるので、確実に係合凹部11aに係合して逆止を安定的に行なうことができる。   By the way, as shown in FIGS. 1A and 1B and FIG. 7, it is preferable that the engaging portion 11 (engaging recess 11a) is provided through in the vertical direction. According to this configuration, as described above, the engaging recess 11a has an area between the upper and lower portions as it is as an engaging area with the check claw of the engaging means, so that the stability during engagement is improved. That is, since the engaging recess 11a is formed so as to be recessed inward when viewed in parallel with the axial direction of the nail, the engageable area becomes larger. By forming it long vertically like the pawl 30, a non-return function can be exerted by engaging even a small amount in the region between the upper and lower sides of the engaging recess 11 a. Can be stably stopped.

係合部11を上下方向に通しで設けるとは、係合部11が上下方向(垂直でも斜めでもよい)に障害なく通るように形成されていればよいということである。また、上下方向とは垂直という意味ではなく、図9(a)〜(c)に示されるように、釘保持部8又は連結部9に形成された係合凹部11aを釘軸1aに対して斜め通しに形成したものも含むものとする。この場合、上下の係合凹部11aが、釘軸1aに対して斜め方向に沿って視たときに外側に向かって突出し又は内側に凹むように形成されているので、係合手段の逆止爪はこれに対応し、上記係合凹部11aの向きに対応するように形成すればよい。この構成によれば、釘軸を斜めに配置できるので、釘の送り方向の自由度が上がる。   Providing the engaging part 11 in the vertical direction means that the engaging part 11 needs to be formed so as to pass in the vertical direction (which may be vertical or oblique) without hindrance. Further, the vertical direction does not mean vertical, but as shown in FIGS. 9A to 9C, the engaging concave portion 11a formed in the nail holding portion 8 or the connecting portion 9 is provided with respect to the nail shaft 1a. Including slant-through ones. In this case, the upper and lower engaging recesses 11a are formed so as to protrude outward or to be recessed inward when viewed in an oblique direction with respect to the nail shaft 1a. Corresponding to this, it may be formed so as to correspond to the direction of the engaging recess 11a. According to this configuration, since the nail shaft can be arranged obliquely, the degree of freedom in the nail feeding direction is increased.

以上のことは、係合部が外側に向かって突出する係合凸部11bの場合であっても同様である。   The above is the same even if the engaging portion is the engaging convex portion 11b protruding outward.

なお、ガイドチューブ2は必ずしも必要ではない。図9(a)の連結釘Aのように釘長が短いものは射出口5内で傾く角度が大きいからガイドチューブ2は有効であるが、図23(b)の連結釘Aのように長寸の釘1は射出口5内での傾き角度は小さいので、なくてもよい。   The guide tube 2 is not always necessary. The guide tube 2 is effective when the nail length is short, such as the connecting nail A in FIG. 9A, because the angle of inclination in the injection port 5 is large. However, the guide tube 2 is long as in the connecting nail A in FIG. The size of the nail 1 is not necessary because the inclination angle in the injection port 5 is small.

(複数の連結釘と釘打機との組み合わせ)
なお、上記各連結釘について、係合凹部11aの高さや釘軸の長さは異なるが、係合凹部11aの形状が同じで、釘軸方向に沿って連続的に形成されるいくつかの種類の連結釘と共通の釘打機と組み合わせることもできる。この場合、図22(a)(b)に示されるように、釘打機は組み合わせに供された各連結釘A、A´を個別に装填可能で、図23(a)(b)に示されるように、その係合手段の逆止爪30は上記連結釘A、A´のうち上下の係合凹部11a間の間隔H1、H2のうち大きい方の係合凹部11a(図23(b)に示す)に係合可能に形成されるようにすればよい。これにより、連結釘を送る際に共通の逆止爪30によって種類の異なる連結釘A、A´が逆方向に移動するのを確実に防止することができる。係合部が係合凸部であっても、あるいは係合部が釘軸に対して斜めに設けられていても同様である。
(Combination of multiple connecting nails and nailing machine)
For each of the connecting nails, the height of the engaging recess 11a and the length of the nail shaft are different, but the shape of the engaging recess 11a is the same and several types are formed continuously along the nail axis direction. It can also be combined with a common nailing machine. In this case, as shown in FIGS. 22 (a) and 22 (b), the nailing machine can individually load the connecting nails A and A ′ provided for the combination, as shown in FIGS. 23 (a) and 23 (b). As shown in FIG. 23, the check claw 30 of the engaging means has a larger engaging recess 11a (see FIG. 23 (b)) among the intervals H1 and H2 between the upper and lower engaging recesses 11a of the connecting nails A and A ′. As shown in FIG. Thereby, when sending a connection nail, it can prevent reliably that different types of connection nail A and A 'move to a reverse direction with the common check nail | claw 30. FIG. The same applies even if the engaging portion is an engaging convex portion or the engaging portion is provided obliquely with respect to the nail axis.

なお、上下の係合部間の間隔は、図1の連結釘Aの係合部(係合凹部11a)のように連続的に形成された場合は、そのまま上下端部間の寸法であり、図23(a)の連結釘Aや同図(b)の連結釘A´の係合部(係合凹部11a)のように、上下の連結帯3に形成された係合部11が釘軸方向に沿って形成されている場合の係合部間間隔H1、H2は、上段の連結帯3の係合部(係合凹部11a)から下段の連結帯3の係合部(係合凹部11a)までの寸法である。   In addition, when the space between the upper and lower engaging portions is formed continuously like the engaging portion (engaging recess 11a) of the connecting nail A in FIG. Like the engaging portion (engaging recess 11a) of the connecting nail A in FIG. 23 (a) and the connecting nail A ′ in FIG. 23 (b), the engaging portion 11 formed on the upper and lower connecting bands 3 is the nail shaft. The distance H1, H2 between the engaging portions when formed along the direction is from the engaging portion (engaging recess 11a) of the upper connecting band 3 to the engaging portion (engaging recess 11a of the lower connecting band 3). ).

上述のような複数の種類の連結釘A、A´と共通の逆止爪30を有する釘打機との組み合わせによれば、逆止爪を共通化することができ、連結釘毎に逆止爪30を変えたり、釘打機を変えたりする必要がないので、全体のコストを格段に抑えることができる。しかも、組み合わせの規模が大きくなるので、上記効果もさらに増大する。   According to the combination of a plurality of types of connecting nails A and A ′ as described above and a nailing machine having a common check claw 30, the check claw can be shared, and the check nail is connected to each connecting nail. Since it is not necessary to change the nail 30 or the nailing machine, the overall cost can be significantly reduced. In addition, since the scale of the combination is increased, the above effect is further increased.

(曲げシート連結方式の連結釘の実施形態)
次に、図10〜図13は曲げシート連結方式の連結釘を示すもので、連結釘Aは、細長の合成樹脂製連結帯3の長辺部3bの両側から一定の間隔をおいて釘1を保持する釘保持部8を形成することにより、側面視においてコ字形形状をなすように構成されている。連結帯3は、上述のものと同じ材質で、その外面は滑らかに形成されている。
(Embodiment of connecting nail of bending sheet connecting method)
Next, FIG. 10 to FIG. 13 show a connecting nail of a bending sheet connecting type. The connecting nail A is a nail 1 at a certain interval from both sides of the long side portion 3b of the elongated synthetic resin connecting band 3. By forming the nail holding portion 8 that holds the heel, it is configured to have a U-shape when viewed from the side. The connecting band 3 is made of the same material as described above, and its outer surface is smoothly formed.

なお、連結帯3と釘保持部8とは、側面視においてコの字形の形状に限定されない。連結帯を平面でなく、断面が円弧状の曲面とし、2つの平行な釘保持部8とともに、側面視がU字形をなすように形成してもよい。また、連結帯を平面状とし、2つの釘保持部を非平行とし、全体が側面視V字形をなすように形成してもよい。   The connecting band 3 and the nail holding portion 8 are not limited to a U-shape when viewed from the side. The connecting band may be a curved surface having an arc-shaped cross section instead of a flat surface, and the two parallel nail holding portions 8 may be formed so as to form a U shape in a side view. Further, the connecting band may be planar, the two nail holding portions may be non-parallel, and the whole may be formed in a V shape when viewed from the side.

図10及び図11に示す連結釘Aの連結帯3の外面には、釘保持部8の基部から連結帯3にかけて内側に凹むように切り欠くことによって係合部として係合凹部11aが形成されている。この係合凹部11aは上下方向に通しで形成されている。   On the outer surface of the connection band 3 of the connection nail A shown in FIGS. 10 and 11, an engagement recess 11 a is formed as an engagement part by notching so as to be recessed inward from the base of the nail holding part 8 to the connection band 3. ing. The engaging recess 11a is formed through in the vertical direction.

上記形態においても、連結帯の外縁部3a、つまり連結帯3の外側面部は略真直に、逆止爪が係合できない程度に滑らかに形成するのが好ましい。   Also in the said form, it is preferable to form the outer edge part 3a of a connection belt | band | zone, ie, the outer surface part of the connection belt | band | zone 3, substantially straight and smoothly so that a non-return claw cannot be engaged.

上記構成によれば、係合凹部11aは上下方向に通しで設けられているので、上下間の領域がそのまま係合手段の逆止爪に対して係合可能となるため、確実に逆止爪に係合し、係合時の安定性が向上する。すなわち、図23(a)の場合と同様、逆止爪30が連結釘Aの係合凹部11aの上から下までの全領域に係合することができるから、連結帯3がずれたり、曲がったりしても逆止爪は確実に係合凹部11aに係合する。   According to the above configuration, since the engaging recess 11a is provided through in the vertical direction, the region between the top and bottom can be directly engaged with the check claw of the engagement means, so The stability at the time of engagement is improved. That is, as in the case of FIG. 23 (a), the check claw 30 can engage with the entire area from the top to the bottom of the engagement recess 11a of the connection nail A, so that the connection band 3 is displaced or bent. Even if it is, the check claw surely engages with the engaging recess 11a.

また、上記構成によれば、上下の釘保持部8を連結している連結帯3の一部に係合凹部11aが形成される構造であるから、係合凹部11aが形成されていない部分によって強度が保持されるので、必要な強度を確保することができる。   Moreover, according to the said structure, since it is a structure where the engagement recessed part 11a is formed in a part of the connection belt | band | zone 3 which connects the upper and lower nail holding | maintenance part 8, it is by the part in which the engagement recessed part 11a is not formed. Since the strength is maintained, the necessary strength can be ensured.

上記形態の連結ファスナーにおいても、係合部11を上下方向に通しで設けるとは、係合部11が上下方向(垂直でも斜めでもよい)に障害なく通るように形成されていればよく、多少湾曲してもかまわないということである。   Also in the connection fastener of the said form, providing the engaging part 11 in the up-down direction should just be formed so that the engaging part 11 may pass in the up-down direction (it may be perpendicular | vertical or diagonal) without obstacle, It does not matter if it is curved.

ところで、上記係合部は、図12(a)〜(d)のように、連結帯3から突出した係合凸部11bによって構成してもよく、また上下に連続する形態に限定されない。係合凸部11bは、図12(a)(c)(d)のように連結帯3の上下両側に形成してもよく、又は同図(b)のように釘保持部8の中央部に設ける構成としてもよい。これらの係合凸部11bは細長帯状の平シートを切起すことによって形成すればよい。切起こしによって係合凸部11bを形成する場合、切起し以外の部分によって強度が保持される。   By the way, the said engaging part may be comprised by the engaging convex part 11b which protruded from the connection belt | band | zone 3 like FIG. 12 (a)-(d), and is not limited to the form which continues up and down. The engaging protrusions 11b may be formed on both upper and lower sides of the connecting band 3 as shown in FIGS. 12A, 12C, and 12D, or the central portion of the nail holding portion 8 as shown in FIG. It is good also as a structure provided in. What is necessary is just to form these engagement convex parts 11b by cutting and raising a long strip-shaped flat sheet. In the case where the engaging projection 11b is formed by cutting and raising, the strength is maintained by a portion other than the cutting and raising.

なお、上記曲げシート連結方式の連結釘Aにおいて、図10、図11のように、連結帯3のうち、隣り合う釘保持部8間の連結部9の上下部には、切欠き部46が形成されている。この切欠き部46によって連結部9は連結帯3の面に対して直交する方向に曲げやすくなるため、連結釘Aをコイル状に巻き回すことができる。切欠き部46はなくてもよい。   In addition, in the connecting nail A of the bending sheet connecting method, as shown in FIGS. 10 and 11, the notches 46 are formed on the upper and lower portions of the connecting portion 9 between the adjacent nail holding portions 8 in the connecting band 3. Is formed. Since the notch 46 facilitates bending of the connecting portion 9 in a direction perpendicular to the surface of the connecting band 3, the connecting nail A can be wound in a coil shape. The notch 46 may not be provided.

なお、この形態の場合においても、係合凸部11bは連結帯3の釘保持部分に設ける形態に限定されない。例えば、図13(a)〜(c)に示されるように、連結部9に形成してもよい。   Even in the case of this form, the engagement convex part 11b is not limited to the form provided in the nail holding part of the connection band 3. For example, as shown in FIGS. 13A to 13C, the connecting portion 9 may be formed.

これによれば、釘保持部8の強度が全く損なわれないので、係合領域を大きくすることができる。   According to this, since the strength of the nail holding part 8 is not impaired at all, the engagement area can be enlarged.

そのほか、連結帯の全てに係合部が形成されている必要はない。連結帯3の上又は下に係合部が配置されていればよく、図14(a)の連結釘Aのように、連結帯3が上下に配置された構造であって、いずれかの連結帯3に係合凸部11bが形成されているような形態でもよい。また、同図(b)のように、係合部材44に係合凸部11bを形成する構成であってもよい。係合部材44はガイドチューブを兼用するようにしてもよい。   In addition, it is not necessary that the engaging portion is formed on all of the connecting bands. It is only necessary that the engaging portion is disposed above or below the connection band 3, and the structure is such that the connection band 3 is disposed vertically as in the connection nail A of FIG. The form in which the engagement convex part 11b is formed in the belt | band | zone 3 may be sufficient. Moreover, the structure which forms the engaging convex part 11b in the engaging member 44 as shown in the figure (b) may be sufficient. The engaging member 44 may also serve as a guide tube.

ところで、上述の実施形態は、いずれも係合凹部11bが釘保持部8に上下方向に通しで形成されている。このように、上述の図1(a)(b)や図8の場合と同様に、逆止爪を上下に長く形成することにより、逆止爪が係合凹部11bの上下間の領域に少しでも位置していれば係合することができるから、確実に係合部に係合して逆止を安定して行なうことができる。また、係合凸部11も上下方向に通しで形成されていることにより同様の効果を得ることができる。   By the way, as for the above-mentioned embodiment, the engaging recessed part 11b is formed in the nail holding | maintenance part 8 by passing up and down in all. Thus, as in the case of FIGS. 1 (a) and 1 (b) and FIG. 8 described above, the check pawls are formed long in the vertical direction, so that the check pawls are slightly placed in the region between the upper and lower sides of the engaging recess 11b. However, since it can engage if it is located, it can engage with an engaging part reliably and can perform non-return stably. Moreover, the same effect can be acquired because the engaging convex part 11 is also formed through in the up-down direction.

なお、図15(a)(b)の係合凹部11a及び同図(c)(d)の係合凸部11bに示されるように、係合部11は釘軸1aに対して斜めに形成してもよい。この場合は、係合領域が拡大するほかに、さらに釘軸を斜めに配置することにより、釘の送り方向の自由度を上げることができる。   15A and 15B and the engaging convex portion 11b shown in FIGS. 15C and 15D, the engaging portion 11 is formed obliquely with respect to the nail shaft 1a. May be. In this case, in addition to enlarging the engagement area, the nail shaft can be further arranged at an angle to increase the degree of freedom in the nail feed direction.

また、連結部9は連結帯3の一側に配置される形態に限定されない。図16(a)(b)(c)の連結釘Aの連結部9のように、連結帯3の長手方向の中央に沿って、つまり連結帯3の中心線上に形成する構成であってもよい。この場合は、連結釘Aを渦巻状に巻き回して使用することも、また真直状態のまま使用することもできる。ファスナー保持部と連結部との境界部にも係合手段の送り爪や逆止爪が係合しそうであるが、係合部と境界部の連結帯中心線からの高さが異なるため、この場合、逆止爪の揺動角を小さく設定することによって逆止爪が係合凹部11a、係合凸部11bのみに確実に係合する。また、係合手段に対する係合部位が1箇所となるので連結ファスナーの送りと逆止を良好に行なうことができる。   Moreover, the connection part 9 is not limited to the form arrange | positioned at the one side of the connection belt | band | zone 3. Like the connecting portion 9 of the connecting nail A in FIGS. 16A, 16 </ b> B, and 16 </ b> C, the structure is formed along the center of the connecting band 3 in the longitudinal direction, that is, on the center line of the connecting band 3. Good. In this case, the connecting nail A can be used by being spirally wound, or can be used in a straight state. The feeding claw and check claw of the engaging means are likely to engage also at the boundary portion between the fastener holding portion and the connecting portion, but the height from the connecting band center line of the engaging portion and the boundary portion is different. In this case, by setting the swing angle of the check claw to be small, the check claw is surely engaged only with the engagement concave portion 11a and the engagement convex portion 11b. Moreover, since the engagement part with respect to an engagement means becomes one place, a connection fastener can be sent and checked favorably.

(係合部を釘送り用とした実施形態)
次に、上述の実施形態に係る連結ファスナーの係合部は全て釘打機等の打ち込み工具の逆止爪に係合する構成であるが、係合部は逆止用ではなく、釘送り用として構成してもよい。この場合、図24(a)に示されるように、連結釘Aの釘通路16の送り爪側に係合凹部11aが形成されている。
(Embodiment in which the engaging portion is for nail feeding)
Next, all of the engaging portions of the connecting fastener according to the above-described embodiment are configured to engage with a check claw of a driving tool such as a nail driver, but the engaging portion is not for check but for nail feeding. You may comprise as. In this case, as shown in FIG. 24A, an engaging recess 11a is formed on the feed claw side of the nail passage 16 of the connecting nail A.

釘通路16の釘送り機構27には、図18(a)の形態と同様に、釘送りシリンダ23と送りピストン24と送りロッド25が一体に設けられ、送りロッド25の先端には送り爪部材26が回動可能に取り付けられている。送り爪部材26は常時釘通路16の内側に進入するように付勢され、その内側には2つの送り爪26aが形成されている。また、逆止爪部材30はドア22に回動可能に取り付けられ、先端は常時釘通路16の内側に進入するように付勢されている。   The nail feed mechanism 27 of the nail passage 16 is integrally provided with a nail feed cylinder 23, a feed piston 24, and a feed rod 25 as in the embodiment of FIG. 26 is rotatably attached. The feed claw member 26 is always urged to enter the inside of the nail passage 16, and two feed claws 26a are formed on the inside thereof. Further, the check claw member 30 is rotatably attached to the door 22 and its tip is always urged to enter the inside of the nail passage 16.

連結釘Aがマガジン12に装填された後、釘送り機構27が作動すると、送りピストン24はいったん図24(b)に示すように後退した後、同図(c)のように前進する。前進したとき、送り爪26が連結釘Aの上下の連結帯3の係合凹部11aに係合し、先頭の釘1を射出口5内に供給する。その後、上記釘1が同図(a)のように打ち出された後、送りピストン24は同図(b)のように再び後退するが、このとき連結釘Aも逆方向に移動するように作用する。ところが、逆止爪30が連結帯3の凹部10に係合するので、連結釘Aは移動できず同じ位置にとどまる。このため、送り爪部材26が退避方向に回動し、次位の係合凹部11aに確実に係合する。なお、送りピストン24が前進するときは、逆止爪30は退避作動する。   When the nail feed mechanism 27 is actuated after the connecting nail A is loaded in the magazine 12, the feed piston 24 once retracts as shown in FIG. 24B and then advances as shown in FIG. When moving forward, the feed claw 26 engages with the engagement recesses 11 a of the upper and lower connection bands 3 of the connection nail A to supply the leading nail 1 into the injection port 5. After that, after the nail 1 is driven out as shown in FIG. 5A, the feed piston 24 moves back again as shown in FIG. 5B. At this time, the connecting nail A also moves in the opposite direction. To do. However, since the check claw 30 engages with the recess 10 of the connection band 3, the connection nail A cannot move and stays at the same position. For this reason, the feed claw member 26 rotates in the retracting direction and reliably engages with the next engagement recess 11a. When the feed piston 24 moves forward, the check pawl 30 is retracted.

なお、上述の平シート連結方式だけでなく、図10〜図13、図15等に示した曲げシート連結方式の連結ファスナーや、図14(a)(b)に示した連結方式の連結ファスナーであっても係合部(係合凹部、係合凸部)を送り爪に係合可能とすることによって釘送り用として機能させることができる。   In addition to the flat sheet connection method described above, the connection fasteners of the bending sheet connection method shown in FIGS. 10 to 13, 15, etc., and the connection fasteners of the connection method shown in FIGS. Even if it exists, it can be made to function as an object for nail feeding by making an engaging part (engagement recessed part, engagement convex part) engage with a feed nail.

上述のように、係合部は凹状であれ、凸状であれ、釘軸に沿うか、あるいは釘軸に対して斜め方向に沿って形成されているので、上述のように、釘打機の逆止爪又は送り爪の形状を単純化しても確実に係合して有効に逆止又は釘送りの効果が得られる。したがって、係合部を凹状にしたときはその深さ、凸状にしたときはその高さを低く抑えることができる。さらに、係合部の深さや高さの寸法を小さく抑えることができれば、逆止爪又は送り爪の係脱のための移動量も小さく抑えることができ、釘打機をコンパクトにすることができる。このように、いろいろな面に相乗的な効果を期待することができる。   As described above, since the engaging portion is concave or convex, it is formed along the nail axis or along the oblique direction with respect to the nail axis. Even if the shape of the check claw or the feed claw is simplified, it can be reliably engaged and the effect of the check or nail feed can be obtained effectively. Therefore, when the engaging portion is concave, its depth can be kept low, and when it is convex, its height can be kept low. Furthermore, if the depth and height dimensions of the engaging portion can be kept small, the amount of movement for engaging and disengaging the check pawl or feed claw can also be kept small, and the nailing machine can be made compact. . In this way, synergistic effects can be expected in various aspects.

(連結ファスナーの種類)
なお、連結ファスナーは連結釘に限定されない。連結ネジ、連結打込みネジ等であってもよい。打ち込み工具も釘打機に限定されない。ネジ打ち機など、ファスナーの種類に応じた打ち込み工具であればよい。
