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 ().

Support foot for applying and distributing forces to a pressure-sensitive substrate as well as a stand system having such a support foot

A wrench fitted with a handle and a ring that can be swiveled open to grip a screw head or a nut with a positive fit, whereby the ring has a first segment that is arranged on the handle, and a free second segment as well as a connecting member that joins the second segment to the first segment in an articulated manner. A lever is provided on the connecting member so that the ring that can be swiveled open.

Wrench

A fastening device () for mounting on a mounting rail () having a rear-engagement member () which is configured to be introduced into the mounting opening () and to engage behind the rims () of the mounting opening () of the mounting rail (); including a tensioning device () which cooperates with the rear-engagement member () and has a longitudinal axis, for clamping the fastening device () to the mounting rail (); including a contact plate () for resting on the outside of the mounting rail () that has a feed-through opening for a part of the tensioning device (); and a spring element () configured between the contact plate () and the rear-engagement member () for preloading the rear-engagement member () circumferentially with respect to the longitudinal axis () of the tensioning device (); including a holding device () between the rear-engagement member () and the contact plate () for holding the rear-engagement member () in the preloaded position; upon release of the holding device (), the rear-engagement member () being movable by the spring element () from the insertion position to a rear-engagement position where it engages behind the rims () of the mounting opening (). One stop element () having a stop face for limiting the capacity of the rear-engagement member () for twisting rotation is provided on the contact plate ().

Fastening device for mounting on a mounting rail

A clamp for linking a mounting rail to a flange of a beam is disclosed. The clamp includes a lower base, an upper base, a connecting web, and a T-shaped back-gripping element, which is disposed at the lower base for gripping a rail opening of the mounting rail from behind. In the upper base, a threaded hole, which corresponds to the lower T-shaped back-gripping element, is provided for a clamping screw, with which the flange and the mounting rail can be pressed against one another when the lower T-shaped element grips a rail opening of the mounting rail from behind. In the lower base, a threaded hole, which corresponds to an upper T-shaped back-gripping element, is provided for a clamping screw, with which the flange and the mounting rail can be pressed against one another when the upper T-shaped element grips a rail opening of the mounting rail from behind.

Clamp

The invention relates to a fastener () for arranging a rod element () on a mounting channel, said fastener () including an engaging part () that can be inserted and made to engage behind edges () of an installation opening of the mounting channel, whereby the engaging part () has an opening () with an internal thread for the rod element, a stop plate () for making contact on the outside of the mounting channel having a hole () through which the rod element () passes, and flexible connection elements () that connect the engaging part () to the stop plate () at a distance from each other. Moreover, a nut element () that has a hole () with an internal thread and that serves to secure the rod element () to the mounting channel can be rotatably held on the stop plate () using a holding device ().
