  • Patent number: 7914005
    Abstract: A hand-held setting tool (10) includes a connection element (16) for connecting the setting tool (10) with a positioning device (20) having a switching link (30) for connecting the actuation element (24) to the actuation switch (13) of the setting tool (10), and a safety device (50) for preventing actuation of the actuation switch (13) at an orientation of the setting tool (10) other than a predetermined orientation and including at least three blocking members (55a, 55b, 55c) displaceable in at least three separate channels (56) respectively, and receivable in a recess (51) formed in a first, switching element (34) of the switching link (30) with the channels (56) being inclined with respect to a plane (E) extending perpendicular to a longitudinal axis (A) of the positioning device, and with at least three channels (56) intersecting, in some regions, an axial projection of the switching element (34).

  • Patent number: 7913888
    Abstract: A positioning device for a hand-held setting tool (10) includes an actuation element (24), a switching link (30) for connecting an actuation element (24) to the actuation switch (13) of the setting tool (10) for actuating the same, and a safety device (50) for preventing actuation of the actuation switch (13) at an orientation other than a predetermined orientation of the setting tool (10) and including at least three blocking members (55a, 55b, 55c) displaceable in at least three separate channels (56), respectively, and receivable in a recess (51) formed in a switching member (34), that forms part of the switching link (30) a longitudinal axis with the at least three channels (56) intersecting, in some regions, an axial projection of the switching member (34) in the form of a secant and opened toward the switching member (34) in respective overlapping regions (59).

  • Publication number: 20080296338
    Abstract: A positioning device for a hand-held setting tool (10) includes an actuating switching device having an actuation element (24), a switching link (30) for connecting an actuation element (24) to the actuation switch (13) of the setting tool (10) and having a switching member axially displaceable relative to a stationary, with respect to the holder, structural component, and a safety device (50) for preventing actuation of the actuation switch (13) at an orientation other than a predetermined orientation of the setting tool (10) and including at least three blocking members (55a, 55b, 55c) displaceable in at least three separate channels (56) respectively, and receivable in a recess (51) formed in the switching member (34) and open toward the structural component, with the channels (56) being inclined with respect to a plane (E) extending perpendicular to a longitudinal axis (A) of the positioning device, and with at least three channels (56) intersecting, in some regions, an axial projection of the switching m
