A support foot () for applying and distributing forces to a pressure-sensitive substrate, including a baseplate () for placement onto the substrate and a holder () which is joined to the baseplate () and to which the connecting parts () can be attached, whereby the holder () has a first receptacle () for a first connecting part () and a second receptacle () for a second connecting part (). A stand system has at least one support foot () and at least one, especially C-shaped, mounting rail that is inserted into a receptacle () and that is prevented by a fastener () from being pulled out of the holder ().

A cold rolling method for manufacturing a profile () from a one-piece rolling stock in form of initial material () with a plurality of rolls () each having a deforming region () for deforming the initial material () includes bending the initial material () with formation at least one folded section () extending in a rolling direction of the initial material (), and deforming the initial material () in its width direction with reduction of its thickness at least in one region.

A method of reducing thickness of unbroken rolling stock () by longitudinal rolling includes deforming the rolling stock () in the width direction with deformation regions (toto) of the rolls (toto) penetrating in the rolling stock to the same depth.

A connection element for a bolt and having a bolt-receiving member ( ) the bore of which has a cylindrical receiving region ( ) and a tapering, at least sectionally, in a direction opposite to an insertion direction (A) of the bolt ( ), region ( ) that adjoins the cylindrical receiving region ( ) at its side facing in the direction opposite the insertion direction (A), a guide region ( ) that adjoins the cylindrical receiving region ( ) at its insertion direction side and has an inner diameter (d ) which at most corresponds to an outer diameter of the bolt; and at least one locking member ( ) arranged in the bore ( ), formlockingly engaging, at least partially, in the outer thread ( ) of the bolt ( ), and formed as a radially expandable ring body.

Connection element for connecting a bolt-supported part with the supporting bolt

A connection element for a bolt including a member for receiving the bolt ( ) and including a bore ( ) having a tapering region ( ) adjoining a bore cylindrical receiving region ( ) and tapering in a direction opposite a bolt insertion in direction (A); and a locking member supported in the bore ( ) for forcelockingly engaging the bolt ( ) and formed as a radially expandable annular member having an inner diameter (w), which is, at least partially, smaller than an outer diameter (d ) of the bolt ( ), and an axial length corresponding to an axial length of the cylindrical receiving region ( ).

Connection element

A mounting rail, particularly for use in building construction, is formed by an elongated rail member (2) of approximately C-shaped cross section having a rear wall (3) with spaced openings (7a-7d) therethrough and pair of side walls (4a, 4b) extending from and at substantially right angles to the rear wall (3). The side walls have free edge sections spaced from the rear wall bent inwardly towards one another and forming cross members (5a, 5b) extending generally parallel to the rear wall with the inner edges of the cross members spaced apart and forming a slot (6) extending in the elongated direction of the rail member (2). Each side wall (4a, 4b) has shaped recesses (8a, 8b) extending for the length of the rail member (2). The shaped recesses (8a, 8b) are arranged symmetrically to one another in the opposite sidewalls (4a, 4b) and have a depth of (d) which does not exceed the width (b) of the cross members (5a, 5b) defining the slot (6).

Mounting rail

A fastening element for a C-shaped rail (30) including a rail nut (2) insertable through the rail opening (35) into the interior of the rail (30) when longitudinal sides (6, 7) of the rail nut (2) extend parallel to the longitudinal direction of the rail (30), and pivotable in the interior of the rail (3) so that a longitudinal extent (1) of the rail nut (2), which is larger than the width (w) of the slot-like opening (35), would overlap the opening (35); and a rail clip (3) overlapping the rail nut (2) at least in some areas and spaced from the rail nut by an axial distance (d), which is reduced upon clamping the free ends (33, 34) of the shoulders (31, 32) the rail clip (3) being formed as one-piece with the rail nut and being connected with the rail nut (2) by a connection link attached to an edge of the rail nut (2) so that with the longitudinal sides (6, 7) of the rail nut (2) extending parallel to the longitudinal extent of the opening (35), it would engage the free end (33) of one should (31) and, with the longitudinal sides (6, 7) of the rail nut (2) being pivoted with respect to the longitudinal extent of the opening (35), it would engage the free end (34) of the opposite shoulder.
