  • Patent number: 9080335
    Abstract: The invention relates to a scaffolding component (45) with at least one connection head (61) for forming a releaseable connection with a vertical scaffolding element (41) extending in the direction of a longitudinal axis (47). On this scaffolding element is fastened a projection (44) which extends transversely to its longitudinal axis (47) and which has an aperture (55) for the insertion of a wedge (62). The connection head has an upper head part (74) with an upper wedge opening (80) and a lower head part (75) with a lower wedge opening (81), for the wedge (62) which can be inserted through the wedge openings (80, 81). Disposed between the upper head part (74) and the lower head part (75) is a slot (67) which is open towards the front and which is intended for the fitting of the connection head (61) onto the projection (44).

  • Patent number: 6296077
    Abstract: A system of connectors for use in temporary structures to connect the bracing members of open lattice towers and trusses to the legs of towers and chords of trusses and space frames. A connector is permanently fitted to each end of all bracing members. The connector is configured to engage a cylinder (or projection) that is integral to the leg (or chord as the case may be). After one end is engaged on a cylinder (projection) the member is rotated about the engaged end until the connector on the opposing end of the member engages a corresponding cylinder (projection) on the opposed leg or chord. Installation of the next member using the method as described permanently locks the previously installed member in place such that it can not be removed until the member that was installed after it is removed. The assembly sequence is therefore fixed and begins at the bottom of a tower leg or one end of a truss chord. Disassembly requires following a sequence that is exactly the reverse of the assembly sequence.

Base plates (13) are also positioned between the cross struts (12) of neighboring carrier frames (43). Diagonal poles (27) are arranged between at least some of the neighboring vertical poles (11). According to the invention scaffolding of this type is configured in such a way that at least one end of the diagonal poles (27) engages in an aperture (16) provided in the designated vertical pole (11) by means of a hook (15, 15′). Said opening lies at least essentially in the plane defined by the axes (17) of the neighboring vertical poles (11).

  • Patent number: 6202788
    Abstract: The invention relates to a pivoting pin (1) for use on scaffold vertical frames (6) as a connecting element for scaffold bars and braces extending in horizontal and/or vertical direction, having a sleeve-like support (2) that may be welded on the vertical frame (6), which support on its bottom has a slot (3) extending in longitudinal direction which is larger in width than a fall bar (5) fitted with a bearing in the interior of support (2) and pivoting around a horizontal axis, which fall bar protrudes downwardly from the slot (3) when in its vertical lock position and may be pivoted out of same solely towards the welded end of the support (2) in the interior thereof to reach its horizontal open position, the pivoting angle being confined to about 90°.
