Abstract: The present disclosure relates to a sealing element for hollow sections, including a seal carrier that extends along a longitudinal axis and has two arms each of which has an outer face and an inner face and which are connected together, as one piece, at longitudinal edges that face each other such that they form a corner angle between them seals mounted on or near a free longitudinal edge of each arm and running parallel to the free longitudinal edge, on the outer face of the associated arm, and a securing device, on at least one inner face of an arm, for detachably securing the sealing element onto a corner of a hollow section. A cover cap serves to complete the sealing elements, the cap being provided, on its outer face, with one or more sealing sections designed to connect to ends of the seals of the sealing element.

Abstract: A corner connector for hollow profiles is provided, including a base element having a first and a second wall section connected at a right angle and in one piece to each other on one respective lateral edge that forms a connecting edge, a first guide and connection groove extends from a lateral edge that is adjacent and in parallel to the connecting edge, and at least one essentially plate-shaped, rectangular additional element, wherein two guide and connection projections protrude from its inner side complementary to the first guide and connection grooves which can be inserted into the first guide and connection grooves in a direction parallel to the connecting edge and, in the fully inserted position, secure the additional element flush on the base element in order to form a third wall section arranged at a right angle to the first and the second wall section.

Abstract: The present disclosure relates to a frame piece for a rack, comprising a hollow profile which extends along its longitudinal axis and is brought into its cylindrical profile shape by shaping a substantially flat starting material. The hollow profile on two opposite lateral edges, has a connecting zone for closing the hollow profile at least one tab-type projection being formed on at least one of the lateral edges, said projection extending away from the lateral edge of the hollow profile and being shaped such that it can be brought into engagement with at least one corresponding receptacle on the respective other lateral edge in a clamping or positive manner.

Abstract: The present disclosure relates to a method for producing rectangular or square wall elements from flat sheet metal, including determining a length and width of a wall element, providing a flat sheet metal piece incising two longitudinal edge portions to form two incisions to form two tabs for each longitudinal edge portion separated by a respective incision from the remaining longitudinal edge portion, right-angled folding of a respective strip, formed by the incisions, right-angled folding of the tabs parallel to the longitudinal edge at the level of the base of the associated incision, right-angled folding of the longitudinal edge portions along the longitudinal edge, right-angled folding of the transverse edge portions parallel to the transverse edge to form a strip having a width corresponding to the transverse dimension of the tabs, and right-angled folding of the transverse edge portions along the transverse edge.

Abstract: A rack is presented including a plurality of at least first and second frame pieces adapted to be interconnected, wherein each frame extends along a longitudinal axis. The rack includes a corner connector arranged to interconnect at least the first frame piece and the second frame piece with the longitudinal axes of the first and second interconnected frame pieces arranged obliquely to one another. The rack includes at least first and second bracing units in which, for the purpose of connecting a plurality of frame pieces, the first bracing unit is capable of bracing the first frame piece against the corner connector arranged between the first and second frame pieces to be connected, and the second bracing unit is capable of bracing the second frame piece against the corner connector obliquely to the first frame piece. Each bracing unit includes at least one tensioning element and two force transmission members.
