Abstract
A handrail, in particular for scaffolding structures, for example stairway scaffolding structures, includes at least two handrail segments connected to one another by a connection unit to provide a continuous handrail, wherein at least one handrail securing element for securing the handrail segment to a scaffolding element is secured to at least one of the handrail segments, wherein the connection unit includes two connection elements that can pivot relative to one another about a pivot axis, wherein at least one connection element is/can be connected to one of the handrail segments connected to one another via the connection unit such that it can rotate about an axis of rotation that is not parallel and not orthogonal in relation to the pivot axis.

A handrail for scaffolding structures comprising:
- two handrail segments connected to one another by a connection unit to provide a continuous handrail, wherein at least one handrail securing element is secured to at least one of the two handrail segments for securing the handrail segment to a scaffold element, wherein the connection unit comprises two connection elements axially connected to one another other the direction of a pivot axis such as to be pivotally about the pivot axis relative to one another by a connecting element,
- wherein a first one of the two connection elements is connected to a first one of the two handrail segments, and a second one of the two connection elements is connected to a second one of the two handrail segments,
- wherein at least one of the first one of the two connection elements is connected to the first one of the two handrail segments rotatably relative to the first one of the two handrail segments about a first axis of rotation that is not parallel and not orthogonal in relation to the pivot axis, and the second one of two connection elements is connected to the second one of the two handrail segments rotatably relative to the second one of the two handrail segments about a second axis of rotation that is not parallel and not orthogonal in relation to the pivot axis,
- wherein the first one of the two connection elements has a first axial end section and a second axial end section, and the second one of the two connection elements has a first axial end section and a second axial end section,
- wherein the first one of the two connection elements has in the second axial end section thereof an end face that is angled in relation to the first axis of rotation and that is substantially orthogonal in relation to the pivot axis, and the second one of the two connection elements has in the second axial end section thereof an end face facing the end face of the first one of the two connection elements, the end face of the second one of the two connection elements being angled in relation to the second axis of rotation and being substantially orthogonal in relation to the pivot axis,
- wherein at least one of:
- a first opening being provided in the end face of the first one of the two connection elements concentrically to said pivot axis, the connecting element in association with the first one of the connection elements comprising a first group of latching projections arranged in ring-like configuration about the pivot axis, all the latching projections of the first group of latching projections extending through the first opening and engaging the end face of the first one of the two connection elements from behind, the first group of latching projections being received in the first opening rotatably about the pivot axis, and
- a second opening being provided in the end face of the second one of the two connection elements concentrically to said pivot axis, the connecting element in association with the second opening provided in the end face of the second one of the connection elements comprising a second group of latching projections arranged in ring-like configuration about the pivot axis, all the latching projections of the second group of latching projections extending through the second opening and engaging the end face of the second one of the two connection elements from behind, the second group of latching projections being received in the second opening rotatably about the pivot axis.
