A hollow profile () formed of a flat material () having a width (d) has at least one groove () provided on an outer side of at least one of the plurality of walls () of the profile () and having a bottom () spaced form the outer side by depth (t) and two opposite, substantially flat side walls () extending substantially perpendicular to the bottom (), with the groove depth (t) of the at least one groove () amounting to from 0.5 to 2 times of the material thickness (d) of the flat material ().

Hollow profile

A device for fastening tubular objects includes a C-shaped mounting rail () and a rail nut formed of a hollow profile having at least two constriction areas (and) defining a through-opening () which is formed by two hollow cylindrical sections () extending parallel to a longitudinal axis of the through-opening () and having respective inner thread sections () for receiving a fastening element there between.

Device for fastening tubular objects

A quick-mountable nut, which is capable of at least partially rotation-free axial displacement relative to a threaded bolt (), includes a nut housing (), and a springy holding member () at least partially located in the nut housing () and engaging in at least one screw thread () of the threaded bolt (), with the central through-opening () of the nut housing being formed as a tapering radially inward, inner cone () for receiving the holding member (), and with the holding member () having two, resiliently movable relative to each other, holding sections () having each an even wall section abutting a wall of the inner cone ().

Quick-mountable nut

A system () for connecting mounting rails comprises a base member () and an angular attachment member (). The base member () has an opening () in at least one lateral wall (or) for passage therethrough of a bolt (). The openings () are each provided with a collar (), which can be brought into engagement with the opening () in the attachment member (). The collar () has at least in an axial region a conical section () shaped as a clamping cone. At the time of tightening the bolt, a form- and force-locking connection between the base member () and the attachment member () is created.

System for connecting mounting rails

A quick mounting nut () movable, at least partially, without being rotated, axially to a threaded bolt (), with a springing wire clip () being located in a nut housing () with a continuous coaxial opening (), with the wire clip () at least partially engaging in a bolt thread () and having two legs () which spring relative to one another, with the opening () having an inner cone () which narrows radially from an axial neutral position of the wire clip () and with the wire clip () being movable axially to a limited extent and contacting at least partially inside the inner cone () in its locking position.

Quick mounting nut

A mounting rail with a C-shaped cross-section extends in a length dimension (L) and has a rear or second wall ( ) with side walls ( ) extending at right angles to the second wall. Each side wall ( ) has on its exterior surface ( ) a recess ( ) running in the length dimension (L), whose cross-section is essentially rectangular. To assure optimum stability of the mounting rail, the depth (t) of the recess ( ) is less than the wall thickness (d) of the side walls ( ).

Shaped mounting rail

A quick mounting nut ( ) movable, at least partially, without being rotated, axially to a threaded bolt ( ), with a springing wire clip ( ) being located in a nut housing ( ) with a continuous coaxial opening ( ), with the wire clip ( ) at least partially engaging in a bolt thread ( ) and having two legs ( &prime;) which spring relative to one another, with the opening ( ) having an inner cone ( ) which narrows radially from an axial neutral position of the wire clip ( ) and with the wire clip ( ) being movable axially to a limited extent and contacting at least partially inside the inner cone ( ) in its locking position.

A fastening device for securing tubes, pipes and the like is formed of a mounting rail ( ) having a C-shaped cross-section and an elongated space ( ) and a retaining plate ( ). The retaining plate ( ) has a tapped through hole running transverse to the elongated space ( ), the tapped hole has an internal thread for form-locking reception of a fastening element. Further, the retaining plate ( ) has on the side ( ) facing inwardly from the elongated space ( ), at least one web facilitating rigidity and positioning, in order to provide a manageable and economical fastening device with high load capacities (P).
