Profiled clamp

1 . A profiled clamp having a first profiled clamp section and having a second profiled clamp section, by means of which two flange parts can be connected to one another with the application of an axial force,

wherein a first tightening head is formed at one end of the first profiled clamp section and a second tightening head is formed at one end of the second profiled clamp section in order to form a tightening device,

wherein the ends of the first and second profiled clamp sections which are located opposite the tightening heads are connected to one another via an articulated connection,

wherein the articulated connection is formed via a mechanically machined or formed flat strip section which is connected in one piece to the first and second clamp sections and has a defined flexibility,

wherein the flat strip section has a reduced material thickness in a sheet thickness direction, when compared with the first and second clamp sections,

wherein the flat strip section has at least one notch with a U-shaped or V-shaped cross section, by means of which the reduced material thickness was produced, wherein the at least one notch is embodied as a transverse groove;

wherein the at least one notch extends transversely to the circumferential direction of the clamp over an entire material width of the flat strip section,

wherein the flat strip section has an upper side directed toward a center of the profiled clamp and an underside directed away from the center of the profiled clamp,

wherein the at least one notch does not penetrate the sheet thickness but takes material from the upper side of the flat strip section and thereby thins it additionally, such that the underside of the flat strip section remains unchanged and has no notches.

2 . The profiled clamp as claimed in claim 1 , wherein the profiled clamp has two profiled clamp sections as profiled clamp halves, and the first profiled clamp section is a first profiled clamp half, and the second profiled clamp section is a second profiled clamp half, and the ends of the first and second profiled clamp halves which are located opposite the tightening heads are connected to one another via the articulated connection.

3 . The profiled clamp as claimed in claim 1 , further comprising a third profiled clamp section, and the first profiled clamp section is connected to a first end of the third profiled clamp section via a first articulated connection at the end of the first profiled clamp section which is located opposite the tightening head, and the second profiled clamp section is connected to a second end of the third profiled clamp section via a second articulated connection at the end of the second profiled clamp section which is located opposite the tightening head.

4 . The profiled clamp as claimed in claim 1 , wherein the flat strip section has a stamped feature or milled feature or rolled feature, by means of which the reduced material thickness was produced.

5 . The profiled clamp as claimed in claim 1 , wherein pressure lugs are formed on the end sides of the tightening heads, which pressure lugs come to rest against one another when a screw element is tightened.

6 . The profiled clamp as claimed in claim 5 , wherein the screw element is screwed to a self-locking nut.

7 . The profiled clamp as claimed in claim 1 , wherein the first tightening head has a rectangular aperture through which a screw element with a rectangular shoulder of complementary design can be inserted.

8 . The profiled clamp as claimed in claim 1 , further comprising at least one further profiled clamp section, the at least one further profiled clamp section connected to adjacent profiled clamp sections via articulated connections.

9 . The profiled clamp as claimed in claim 1 , wherein the reduced material thickness of the flat strip section is in the sheet thickness direction, transverse to a circumferential direction.

10 . The profiled clamp as claimed in claim 1 , wherein the reduced material thickness of the flat strip section, which forms the articulated connection, extends over the entire length of the flat strip section or is arranged centered in the circumferential direction of the clamp sections.

11 . The profiled clamp as claimed in claim 1 , wherein the flat strip section has no profiling and is flat transversely to the circumferential direction of the clamp sections, wherein longitudinal sides of the flat strip section are not bent relative to one another, such that the flat strip section is built flat in the axial direction.
