Description
本考案は、連結組立体に関し、特に、折り畳み及び伸展が可能な連結組立体に関する。 The present invention relates to a connection assembly, and more particularly to a connection assembly that can be folded and extended.
折り畳み可能な連結組立体は、使用する際、常に折り畳み組立体（例えば脚立）の中に配置されて働きを発揮し、折り畳み組立体が連結組立体を通じて閉脚及び開脚することができる。従来の折り畳み可能な連結組立体は、位置決め機構が設けられていないため、連結組立体を配置した折り畳み組立体が外力によりその開脚状態に影響を及ぼしやすい。例えば、脚立が開脚状態にある時外部物体の衝突を受けたて少し閉脚するとその開脚が不完全となり、安定性に影響を及ぼす。同時に折り畳み組立体を長期繰り返して使用する場合、振れ・緩みや抜けの現象が生じる可能性がある。 When used, the foldable coupling assembly is always placed in the folding assembly (eg, a stepladder) to perform its function, and the folding assembly can be closed and opened through the coupling assembly. Since the conventional foldable coupling assembly is not provided with a positioning mechanism, the folding assembly in which the coupling assembly is disposed is likely to affect the open leg state by an external force. For example, when the stepladder is in the open leg state, if the leg is slightly closed after receiving a collision with an external object, the leg is incomplete and affects stability. At the same time, when the folding assembly is used repeatedly for a long period of time, there is a possibility that a phenomenon of swinging / loosening or falling out may occur.
これにより、上記問題を解決するため、改良された折り畳み可能な連結組立体が求められていた。 Accordingly, an improved foldable connection assembly has been sought to solve the above problems.

図２、図３Ａ及び図３Ｃを参照すると、連結組立体１０を伸展した時、第１クランク３００及び第２クランク４００が連結部５００を回していると、第１位置決め部３１７及び第２位置決め部４１７が位置決め部材２００と係合することで、回転を停止すると共に位置が固定される。第１位置決め部３１７及び第２位置決め部４１７は、凹溝状とすることができ、凹溝の幅が位置決め部材２００の幅よりやや大きい。連結部材２３０は、制御部２２０から離れた方向に向かって位置決め部材２００に対し推力を加えることで、第１位置決め部３１７及び第２位置決め部４１７を位置決め部材２００と係合した時より緊結させて緩みにくくなる。この時、位置決め部材２００は連結部５００に向けて係合により第１位置決め部３１７及び第２位置決め部４１７の中に入り、制御部２２０を回転軸１６９に沿って回らせ、保護キャップ２５０とキャップ１５０を互に離れさせる。位置決め部材２００、第１位置決め部３１７及び第２位置決め部４１７の係合形状は限定されず、上記固定効果を奏することでよい。図４Ａに示すように、操作部１００は、選択的に両回転範囲制限凸部１１６を含むことで、第１クランク３００と第２クランク４００の開閉時過度回転による位置決め部材２００の損傷を防止できる。 Referring to FIGS. 2, 3A, and 3C, when the connecting assembly 10 is extended, if the first crank 300 and the second crank 400 rotate the connecting portion 500, the first positioning portion 317 and the second positioning portion. By engaging 417 with the positioning member 200, the rotation is stopped and the position is fixed. The first positioning portion 317 and the second positioning portion 417 can be formed in a concave groove shape, and the width of the concave groove is slightly larger than the width of the positioning member 200. The connecting member 230 applies a thrust to the positioning member 200 in a direction away from the control unit 220, thereby causing the first positioning unit 317 and the second positioning unit 417 to be more tightly coupled than when the positioning member 200 is engaged. It becomes difficult to loosen. At this time, the positioning member 200 enters the first positioning portion 317 and the second positioning portion 417 by engagement toward the connecting portion 500, and rotates the control portion 220 along the rotation shaft 169 to protect the protective cap 250 and the cap. 150 are separated from each other.

When moved in a direction away from the portion 417, the engagement state can be released. In the present embodiment, force is applied to the control unit 220 to bring the protective cap 250 close to the cap 150 to rotate the control unit 220 along the rotation shaft 169, and the positioning member 200 is moved through the second portion 220 </ b> B of the control unit 220. By disengaging from the connecting part 500, the engagement state is released, and the first crank 300 and the second crank 400 can be rotated and folded with respect to the connecting part 500. As shown in FIGS. 3D and 4A, the second end 330 of the first crank 300 can be coupled to the first portion 61 of the folding assembly, and the second end 430 of the second crank 400 is connected to the second portion of the folding assembly. 62 can be connected.
