【０００１】[0001]

[Industrial applications]

本考案は、作業台等に使用する継合パイプ脚の係止装置に関するものである。 The present invention relates to a locking device for a joining pipe leg used for a workbench or the like.

【０００２】[0002]

[Prior art]

継合パイプ脚の内外管継合部にあけた貫通孔に、ピン、ボルトナット等を挿着する係止装置としては各種構造のものが提案されているが、公知のものの中には、抜け易かったり或いは固定、取外しに手間を要するもの等が多かった。 Various types of locking devices have been proposed as locking devices for inserting pins, bolts, nuts, etc. into the through holes formed in the inner and outer pipe joints of the jointed pipe legs. Many of them were easy or required fixing and removal.

【０００３】[0003]

[Problems to be solved by the device]

本考案は取扱いが容易で装着後自然脱出等のおそれのない、継合パイプ脚の係止装置を得ようとするものである。 The present invention is intended to provide a locking device for a joining pipe leg that is easy to handle and does not have a risk of spontaneous escape after mounting.

[Means for Solving the Problems]

前記の目的を達成するため、本考案の継合パイプ脚は、脚体を構成する内外管の嵌合部において、内管１と外管２とにそれぞれ水平方向に貫通する差込孔３を設け、該孔に差込んだ丸棒４の一端に、前記外管全面に沿わせて斜下方に延長する垂下部５を形成させたものである。 In order to achieve the above-mentioned object, the joint pipe leg of the present invention has insertion holes 3 penetrating the inner pipe 1 and the outer pipe 2 in the horizontal direction at the fitting portions of the inner pipe and the outer pipe constituting the leg body. A hanging portion 5 is provided at one end of the round bar 4 inserted into the hole and extends obliquely downward along the entire surface of the outer tube.

【０００５】[0005]

[Work]

前記の構成により、丸棒の垂下部５はその自重と外管２へのまといつきにより管側より離れることがなく、従って丸棒４本体部が差込孔３より脱出するおそれがない。 With the above configuration, the hanging portion 5 of the round bar does not separate from the tube side due to its own weight and clinging to the outer tube 2, and therefore the round bar 4 main body portion does not come out of the insertion hole 3.

【０００６】また垂直部５を水平位置（差込孔３の位置）迄引上げれば、丸棒４本体部を回動させるとともに容易に差込孔３より抜取ることができ、また差込孔３を数段に設けたものにおいては、丸棒４を他の孔に差換えて脚の高さを調節することができる。Further, if the vertical portion 5 is pulled up to the horizontal position (the position of the insertion hole 3), the main body of the round bar 4 can be rotated and easily pulled out from the insertion hole 3, and the insertion hole 3 can be easily pulled out. In the case where 3 is provided in several stages, the height of the leg can be adjusted by replacing the round bar 4 with another hole.

The present invention can also be applied to steps, stepladders, scaffolds, etc. that use jointed pipes.

【０００８】[0008]

[Effect of device]

本考案は、継合パイプ脚に使用したとき係止が強固で、差込孔３に差込まれた丸棒４本体部は動揺等により自然脱出のおそれが無いのみならず、取外し及び取付は極めて容易であり、なおパイプ材としては丸棒のほか角管等にも使用し得られる。 The present invention is firmly locked when used for a jointed pipe leg, and the main body of the round bar 4 inserted into the insertion hole 3 is not likely to spontaneously escape due to shaking or the like, and is also removed and attached. Is extremely easy, and it can be used not only for round bars but also for square tubes.
