Abstract:
1. Arrangement of a vertical scaffolding element and of a scaffolding component, said scaffolding component having at least one connection head and a wedge, for formation of a releasable connection with the vertical scaffolding element, wherein a projection is fastened onto said vertical scaffolding element which extends in the direction of a longitudinal axis, wherein the projection extends transversely, in other words in a transverse direction, relative to the longitudinal axis of the vertical scaffolding element, and has a recess in the form of a perforation for inserting the wedge through it, wherein the connection head has an upper head part having an upper wedge opening, and a lower head part having a lower wedge opening, for the wedge that can be inserted through the wedge openings, wherein a horizontal slot that is open toward the front is disposed between the upper head part and the lower head part, for mounting the connection head in a horizontal mounting direction toward the front onto the projection, wherein the horizontal slot is delimited toward the top and toward the bottom with slot surfaces, which extend on both sides of a horizontal center plane of the horizontal slot, wherein the connection head has a wedge support body, disposed above the horizontal slot and projecting over the horizontal slot toward the front, said wedge support body having wedge support surfaces for vertical support of the wedge in the region of its lower wedge end towards the bottom against unintentional movement of the wedge vertically downward into a blockage position, in which mounting of the connection head with its horizontal slot in the horizontal mounting direction toward the front onto the projection would be blocked, wherein the wedge support surfaces of the wedge support body are configured to support the wedge so that a wedge part of the wedge projects out of the upper head part toward the top beyond the upper head part and so that the wedge can be pivoted into a vertical plane that runs perpendicular to the horizontal center plane of the horizontal slot, relative to the connection head, into an impact pivot position that is inclined toward the front, in which impact pivot position the wedge part of the wedge projects out of the upper head part toward the top beyond the upper head part and projects in front of the upper head part of the connection head, toward the front, when the wedge is supported on the wedge support surfaces, wherein the connection head has a wedge pivot counter-bearing above the wedge support surfaces of the wedge support body and projecting toward the front of the slot, wherein the wedge support surfaces allow vertical support of the wedge, towards the bottom, wherein the wedge-pivot counter-bearing is configured so that the wedge can be laid or is laid on the wedge-pivot counter-bearing when the wedge is supported on the wedge support surfaces of the wedge support body, in the region of its lower wedge end, and wherein the wedge-pivot counter-bearing delimits the upper wedge opening toward the rear so that the wedge can be pivoted about the wedge-pivot counter-bearing, when the wedge is supported on the wedge support surfaces of the wedge support body in the region of the lower wedge end and when the wedge is laid against the wedge pivot counter-bearing, toward the rear with its wedge part that projects toward the top beyond the upper wedge opening, and, at the same time, toward the front with its lower wedge end, in order to achieve liberation of the wedge, so that the wedge can automatically move all the way into or through the lower wedge opening as the result of gravity and/or with the support of spring force, vertically toward the bottom, while crossing the horizontal slot.
