Problems solved by technology
[0003] In the case of known groove blocks, there is often the problem that they first have to be moved into a predetermined position relative to the groove or profile groove in order to insert them there
Even in the case of the hammerhead screw known from EP2885545B1 there is a problem because before the screw is placed on the groove it has to be oriented within a predetermined angle of 45 degrees in order to be able to produce the final orientation required for the hammerhead screw. angular momentum of

Embodiment Construction
[0028] According to Figure 1 and figure 2, the fastening device 1 according to the invention has a first part 3 with an undercut groove 2 , eg a profile groove, and a second part 5 with a through hole 4 . Fastening means 6 for fastening the second part 5 to the first part 3 are likewise provided. Here, the second part 5 is fastened to the first part 3 via fastening means 6 which are guided through the through-hole 4 of said second part 5 and engage substantially perpendicularly into the groove 2 . According to the invention, the fastening device 6 also comprises a hammer piece 8 (see also Figure 3 to Figure 7 ) and a retainer 9 that can be screwed onto it. In the state in which the hammer piece 8 and the holder 9 screwed thereto are mounted on the second part 5, they can be rotated without restriction about the axis 12, the hammer piece 8 being on its side facing the groove 2 The sides have orientation profiles 10 configured in such a way that, when pressed onto the groov...

The invention relates to a fastening device (1) - having a first part (3) with an undercut groove (2), - having a second part (5) with a through hole (4), - the second part (5) can be fixed on the first part (3) via a fastening device (6), which is guided through all parts of the second part (5) said through hole (4) and engages perpendicularly into said groove (2), - said fastening device (6) has an axis (12) which in the case of the mounted fastening device (6) Orientated vertically with respect to the groove (2), it is necessary for the invention that the fastening device (6) has a hammer (8) and a holder (9) which can be screwed onto it, - The hammer piece (8) and the holder (9) which can be screwed onto it can move unrestrictedly around the axis (12) in the state where they are mounted on the second part (5). Rotation, - the hammer head (8) has an orientation profile (10) on the side facing the groove (2), the orientation profile (10) is constructed in such a way that when pressed into the In case (2) on the groove (2), they set the orientation of the hammer piece (8) relative to the groove (2) so that it can be independently of the hammer piece (8) around The rotational position of said axis (12) is immersed in it. Thus, the assembly of the fastening device (1) can be greatly facilitated.
Description
technical field [0001] The invention relates to a fastening device having a first part with an undercut groove and a second part with a through hole according to the preamble of claim 1 . Furthermore, the invention relates to a hammer piece of a fastening device of this type configured as a hammer nut or hammer screw. Background technique [0002] EP2885545B1 discloses a universal fastening device having a first part with an undercut groove and a second part with a through hole, said second part being fixable to said first part via a fastening device, The fastening means are guided through the through hole of the second part and engage substantially perpendicularly into the groove of the first part. In this context, the known fastening device has a hammerhead screw with two small lugs at the first end of its shank, that is to say directly adjacent with respect to the head, which protrude into the In the corresponding jaws of the connecting element and thus a limitation of ...
