Abstract (en)
[origin: WO2009065628A1] The invention relates to a method for the production of a latch bolt (1) of a lock armature. The latch bolt (1) is made of a collar bolt (2) that is attached to a displaceable driving rod and a roller (3) that is pivot-supported on the collar bolt (2), wherein the roller (3) and the collar bolt (2) can be fixed relative to each other via a fixing device. The fixing device is made of a sleeve (15) positioned between the roller (3) and the collar bolt (2), said sleeve comprising an upper and a lower ring (50, 51) connected to bars (521 to 524), wherein at least one axially extending tongue (17) projects from the lower ring (51) between the bars (521 to 524) in the direction of the upper ring (50), wherein an undercut is provided on the collar bolt (2) at least over a partial circumference. According to the invention, in order to simplify the production process, said production process comprises at least one deforming operation, wherein the sleeve (15) is deformed by the application of a force such that the at least one tongue (17) engages into the undercut.
