Prop for a three-dimensional framework, connecting assembly for a railing device, and method for attaching a railing device to a prop

摘要

The invention relates to a prop (32.1, 32.3) for a three-dimensional framework, particularly a scaffold (20), comprising a fastening mechanism (38) for attaching a railing device (28) to the prop (32.1, 32.3). The invention also relates to a connecting assembly for a railing device (28), comprising at least one prop (32.1, 32.3) for a three-dimensional framework, especially a scaffold (20), and a railing device (28) which can be attached to the prop (32.1, 32.3) with the help of a fastening mechanism (38). Also disclosed is a method for attaching a railing device (28) to a prop (32.1, 32.3) for a three-dimensional framework, especially a scaffold (20), with the help of a fastening mechanism (38). The fastening mechanism (38) encompasses a locking element which can be swiveled about a swivel pin. In the locked position, the locking surface of the locking element lies across from a bearing surface (43) of a support element that is mounted on the prop (32.1, 32.3). Furthermore, in the locked position and in the operational position of the prop (32.1, 32.3), the locking surface of the locking element is disposed at a vertical distance above the bearing surface of the support element, and/or in the operational position of the prop (32.1, 32.3), the swivel pin is placed at a vertical distance above the locking surface that is in the locking position, preferably also at a vertical distance above the bearing surface of the support element.

主权项

1. An assembly for scaffolding, for a stage, for a staircase, or for a three-dimensional framework, the assembly comprising:
a prop composed of metal and having a longitudinal axis; and a fastening device for fastening at least one railing device to the prop, the fastening device comprising:
a fastening connector containing a pivot axis;a locking element firmly connected with the prop and formed as a locking lever, the locking element having a locking surface for mechanically positive locking the at least one railing device to prevent vertical removal of the at least one railing device in an upward direction when the locking element is in a locking setting; anda mount for the at least one railing device, the mount being formed as a stirrup, the stirrup:
extending in a direction of the longitudinal axis of the prop,being permanently fastened to the prop,having or bounding a passage opening, the passage opening having a circumference, being closed or surrounded at the whole circumference or substantially at the whole circumference, being formed as a vertical receiving slot, and extending in the direction of the longitudinal axis of the prop,comprising a rest element extending in a first direction transversely to the longitudinal axis of the prop away from the prop, the rest element having a horizontal rest surface for vertical support of the at least one railing device, andhaving a support element bounding the passage opening, the support element extending at a transverse spacing from the prop and being connected with the rest element, the support element being for lateral support of a rest part of the at least one railing device; and wherein the locking lever is fastened to the prop via the fastening connector, is pivotable downwardly about the pivot axis of the fastening connector from an unlocking setting into the locking setting, and is pivotable upwardly about the pivot axis of the fastening connector from the locking setting into the unlocking setting; wherein in the locking setting, the locking surface of the locking element lies opposite the horizontal rest surface of the rest element; wherein in the locking setting, the locking surface of the locking element is arranged at a vertical spacing above the horizontal rest surface of the rest element; wherein in the locking setting, the pivot axis of the fastening connector is arranged at a vertical spacing above the locking surface of the locking element; and wherein an end of the at least one railing device can be inserted into the passage opening of the stirrup and a rest part of the at least one railing device can be received by the passage opening of the stirrup.
