〔産業上の利用分野〕
本考案は、命綱などに付設する連結金具に関す
るものである。[Detailed description of the invention] [Field of industrial application] The present invention relates to a connecting fitting attached to a lifeline or the like.
従来の連結金具は、確実に連結することも大切
であるが、体裁を良好にすることも重視されてい
た。
With conventional connecting fittings, it is important to connect them reliably, but also to make them look good.
従来品は、開閉杆を開くとＣ状杆の両端部と、
開閉杆の基端とが角張つている為ロープの装着や
脱着に際し、この角部にロープがひつかかること
があり、それだけ装着や脱着がおくれる欠点があ
つた。
In the conventional product, when the opening/closing rod is opened, both ends of the C-shaped rod and
Since the base end of the opening/closing rod is angular, the rope may get caught in this corner when attaching or detaching the rope, which has the disadvantage that attachment or detachment is delayed accordingly.
特に、命綱に使用する連結金具のように生命に
係る事故防止の為には装着や脱着の操作に0.1秒
をも争う迅速さが要求されることになる。 In particular, in order to prevent life-threatening accidents, such as connecting fittings used for lifelines, fastness of as little as 0.1 seconds is required for attachment and detachment.
本考案はこの点を解決したもので、添付図面を
参照してその構成を詳述する。
The present invention solves this problem, and its structure will be described in detail with reference to the accompanying drawings.
色々な形状の環体１一部に内側に擺動して開口
部を形成する開閉杆２を弾圧状態に設けた連結金
具において、開閉杆２と環体１との軸着部の夫々
の基端部の外側角部１５，１５′を夫々削取して
開閉杆２を開放位置に屈曲したとき軸着部の外側
面に突状部が形成しない湾曲面に形成したことを
特徴とするものである。 In a connecting fitting in which an opening/closing rod 2 that slides inward to form an opening is provided in a resilient state in a part of annular bodies 1 of various shapes, the respective proximal ends of the pivoting portions of the opening/closing rod 2 and the annular body 1 The outer corner portions 15 and 15' of the shaft mounting portion are respectively shaved off to form a curved surface that does not form a protrusion on the outer surface of the shaft attachment portion when the opening/closing rod 2 is bent to the open position. be.
第１図のように例えば命綱７に付設された本案
品を親綱８にかける場合について説明すると、開
閉杆２の先端部を親綱８に押し込むと開閉杆２が
開き、親綱８が環体１内に入り、その瞬間開閉杆
２は弾圧作用により閉じるから親綱８に本案品が
かけられた状態になる。
As shown in Fig. 1, for example, when the product attached to the lifeline 7 is hung on the main rope 8, when the tip of the opening/closing rod 2 is pushed into the main rope 8, the opening/closing rod 2 opens and the main rope 8 is attached to the main rope 8. When the product enters the body 1, the opening/closing rod 2 is immediately closed by the force of pressure, so that the product is hung on the main rope 8.
逆に親綱８から外す場合には開閉杆２を指圧し
て内側に押し込んで開閉杆２を開き、その状態を
維持して親綱８から外すことになる。 Conversely, when removing from the main rope 8, the opening/closing rod 2 is pushed inward with finger pressure to open the opening/closing rod 2, and this state is maintained to remove it from the main rope 8.
このかける動作も、逆に外す動作も生命に係る
事故を防止する為には0.1秒をも争つて早く完了
しなければならないことになる。 In order to prevent life-threatening accidents, both the action of applying and the action of releasing must be completed as quickly as 0.1 seconds.
その際開閉杆２と環体１とが軸着部の個所で屈
曲するが、開閉杆２と環体２との軸着部にある
夫々の基端部の外側角部１５，１５′を、開閉杆
２が開いたとき軸着部の外側面に突状部が形成し
ない湾曲面に形成してあるため、その屈曲個所の
外側面に接触したとしても、親綱８がそこにひつ
かかるようなことがなく、それだけ挿入及び抜出
が容易となる。 At this time, the opening/closing rod 2 and the ring body 1 are bent at the pivoting portion, but the outer corners 15, 15' of the respective proximal ends at the pivoting portion of the opening/closing rod 2 and the ring body 2 are bent. When the opening/closing rod 2 is opened, the outer surface of the pivoting part is formed into a curved surface with no protrusions, so that even if it comes into contact with the outer surface of the bent part, the main rope 8 will be caught there. This makes insertion and removal easier.
〔実施例〕
略Ｃ状の環体１、開閉杆２はステンレス鋼の丸
棒材で形成している。[Example] The substantially C-shaped ring body 1 and the opening/closing rod 2 are made of stainless steel round bars.
環体１の一端部に外側面を円滑に形成した、前
記丸棒材より肉薄な突部９に、開閉杆２の基部に
形成した割溝１０を被嵌し、軸杆１１により軸着
している。 A groove 10 formed at the base of the opening/closing rod 2 is fitted into a protrusion 9 whose outer surface is smoothly formed at one end of the ring body 1 and which is thinner than the round bar material, and is pivoted by a shaft rod 11. ing.
割溝１０の底面に係止凹部１３を形成し、突部
９の内側寄りに係止段部１４を形成し、板状のバ
ネ３の一端部を係止段部１４に係止し、そのバネ
３の他端部を係止凹部１３に係止して開閉杆２を
常に閉じるように設ける。 A locking recess 13 is formed on the bottom surface of the split groove 10, a locking step 14 is formed on the inner side of the protrusion 9, and one end of the plate-shaped spring 3 is locked to the locking step 14. The other end of the spring 3 is locked in the locking recess 13 so that the opening/closing rod 2 is always closed.
突部９の外側角部１５′を弧状の湾曲面に形成
し、開閉杆２が開放位置の方に回動したとき突部
９の湾曲面から突出しないように開閉杆２の軸杆
１１側の外側角部１５を弧状の湾曲面に形成して
いる。 The outer corner 15' of the protrusion 9 is formed into an arc-shaped curved surface, and the pivot rod 11 side of the opening and closing rod 2 is formed so that it does not protrude from the curved surface of the projection 9 when the opening and closing rod 2 is rotated toward the open position. The outer corner portion 15 is formed into an arcuate curved surface.
開閉杆２のほぼ先端寄りに雄螺子１６を形成
し、この雄螺子１６に、先端内縁寄りに突条１７
を有する六角の筒状ナツト５を螺着している。 A male screw 16 is formed almost near the tip of the opening/closing rod 2, and a protrusion 17 is formed on this male screw 16 near the inner edge of the tip.
A hexagonal cylindrical nut 5 having a diameter is screwed on.
開閉杆２の先端面の内側寄りに肉薄にした係合
溝部１８′を有する係止体１８を突設し、係止体
１８の外側角部６′を少し削取して湾曲面に形成
し、環体１の他端寄り内側に係止体１８の外側の
角部６′の湾曲面を受止め、且つ係合溝部１８′に
被嵌する割溝１９′を有する係止面１９を形成し、
環体１の他端部の内側角部６を少し斜めに開閉杆
２と平行に削取して湾曲面に形成し、開閉杆２を
開放位置に屈曲せしめたとき環体１の内側角部６
と開閉杆２との間（図面の場合は筒状ナツト５と
の間）が広くなるようにしてロープの挿入を良好
にしている。 A locking body 18 having a thin engagement groove 18' is provided protruding from the inner side of the tip surface of the opening/closing rod 2, and an outer corner 6' of the locking body 18 is slightly shaved off to form a curved surface. , a locking surface 19 is formed on the inner side near the other end of the ring body 1, which receives the curved surface of the outer corner 6' of the locking body 18, and has a split groove 19' that fits into the engagement groove 18'. death,
The inner corner 6 of the other end of the ring body 1 is cut slightly diagonally parallel to the opening/closing rod 2 to form a curved surface, so that when the opening/closing rod 2 is bent to the open position, the inner corner of the ring body 1 6
The space between the opening and closing rod 2 (in the case of the drawing, the cylindrical nut 5) is widened to facilitate insertion of the rope.
図中符号１２は筒状ナツト５を止める係止突
部、４は係止体１８と環体１の他端部との噛合係
合部である。 In the figure, reference numeral 12 denotes a locking protrusion for locking the cylindrical nut 5, and 4 is a meshing engagement portion between the locking body 18 and the other end of the ring body 1.
本考案は上述の通り構成したから次の効果を有
