Connection device for connecting mounting rails

An attachment element (), includes at least one engagement member () insertable in a mounting opening () of a hollow body () in its first position and engaging holding projections () provided on the hollow body () in its second position, at least one stop () for engaging outer end sides of hollow body rims which limit the mounting opening (), and at least one fastening element () having an expansion body () for laterally displacing the at least one engagement member () from the first position thereof to the second position.

Attachment element

An attachment system for securing a rod member in a mounting opening of a constructional component () includes a receiving sleeve () for receiving the rod member (), and an actuation member () connected with the receiving sleeve () for substantially radially displacing the engagement elements () of the receiving sleeve, which engage the rod member, from a first position in which the rod member is received in the receiving sleeve () to a second position in which the rod member is locked in the receiving sleeve.

Attachment system

An attachment system, which is to be introduced in a mounting opening () of a hollow body (), includes a rear engagement member () for engaging from behind holding projection () of the hollow body (), at least one stop () for engaging edges of outer sides of the hollow body which limit the mounting opening () and connected with the rear engagement member () by a screw, and a device providing for a relative rotational movement between the stop () and the rear engagement member () about an axis of the fastening means () and formed as a transformation device () for converting a translational movement of the screw () relative to the stop () in a rotational movement of the rear engagement member () relative to the stop.

A fastening system () comprises a rear grip part () for introduction into a mounting opening () of an elongated mounting rail () in a first position and for gripping behind the mounting projections () in a second position and a stop () for frontal external loading of the mounting rail (). The stop () is connected to the rear grip part () by means of a threaded bolt (). In addition, on the fastening system () a system is provided for providing a relative rotary movement between the stop () and the rear grip part () about the axis of the bolt (). The system is configured as a transmission system for transforming a translatory movement of the bolt () relative to the stop () into a rotary movement of the rear grip part () relative to the stop ().

Fastening system

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 rail profile is provided with two connection zones ( ) situated opposite to each other and having an essentially C-shaped cross-section and a rear wall ( ) with an essentially V-shaped cross-section. The structural height (a) of the rail profile is minimal because of the rear wall ( ) design and consequently the handling of the rail profile is enhanced.

Double-rail profile

A fastener having a grip member ( ) that is insertable into a mounting space ( ) of a hollow structure ( ) and serves in the detachable fastening of an object to the hollow structure. The grip member ( ) is rotatable inside the hollow structure such that the grip member ( ) grips behind holding projections provided inwardly of the hollow body longitudinal walls. The holding projections are for fastening of the object between a stop ( ), that outwardly abuts the edges of the hollow structure's longitudinal walls ( ) lining the mounting space and can be fixedly clamped to the grip member ( ). A spring biased element ( ) acting perpendicular to the stop ( ) is arranged between the grip member and the stop. The result is that pre-fixation of the fastener to the hollow structure is made possible. By means of a coupling ( ) between the stop ( ) and the rear grip member ( ) its positions are precisely fixed.

Rail fastener

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 ( ).
