The invention relates to a pivoting pin (,) for use on scaffold vertical frames (,) as a connecting element for scaffold bars and braces extending in horizontal and/or vertical direction, having a sleeve-like support (,) that may be welded on the vertical frame (,), which support on its bottom has a slot (,) extending in longitudinal direction which is larger in width than a fall bar (,) fitted with a bearing in the interior of support (,) and pivoting around a horizontal axis, which fall bar protrudes downwardly from the slot (,) when in its vertical lock position and may be pivoted out of same solely towards the welded end of the support (,) in the interior thereof to reach its horizontal open position, the pivoting angle being confined to about 90&deg;. In order to ensure functional security, particularly when exchanging or replacing the fall bar (,) under unfavorable ambient conditions on the building site, the invention suggests that the slot (,) be closed at its front, the fall bar (,) coming to a stop at the slot front wall when pivoted in forward direction into its lock position.

Latch for scaffold

A connecting device is provided for a bearing bar consisting of a tube having such a connecting device at each of its two ends. The connecting device may be used to join horizontal and vertical scaffolding elements. The connecting device consists of a bearing head and a clamping device and is of such a design that its top edge lies in a plane with that of the tube attached thereto. In addition, the connecting device has bolts for a non-positive connection with overlying elements suspendable thereover. These constructional features of the connecting device allow the overlying elements, which have holes or eyelets to be pushed over the bolts of the bearing bar for suspending in the scaffold, to be placed close up to the post elements, so that virtually no gap between the overlying element and the post element is formed. Moreover, the length of the bearing bars may be dimensioned in such a way that frame scaffoldings and modular scaffoldings can be combined as result of an identically adjustable axial spacing of the pair of posts of a modular scaffolding with respect to the axial spacing of a frame scaffolding.
