Definitions

Zieh-Fix There are demolition tools that work with lag screws and in stores are known under the name Zieh-Fix. These tools work like a corkscrew.
the lag screws have at the front end of their threaded shank a cutting tool with which the screw in the cylinder core, e.g. B. cuts in the area of the key channel.
the cutting means forms a hole in which the threads are of the screw shaft. With such a lag screw tensile forces above the DIN standard are easily exerted.
Such tools are not only used by authorized locksmiths, but unfortunately also used by burglars.
pins with a round cross-sectional profile have been integrated into the cylinder core. The penetration of the lag screws could not be prevented. In some cases, a counter effect was even achieved; the round pins served as guides for the lag screws.
the invention goes a new way, it does not try the locking cylinder to reinforce, but takes precautions in the front area of the Lock cylinders that destroy the intrusion tool. Not the intrusion tool destroys the lock cylinder, but vice versa, the lock cylinder the intrusion tool. This is the effective way to attempt the break-in prevented. This is done by at least one sharp cutting edge achieved a hard metal insert in the cylinder core, which in immediate Proximity to the key channel is arranged. Will the aforementioned lag screw intented to break into the key channel, so grinds the sharp cutting edge of the insert when turning the screw cutting tool from the tip of the lag screw and prevents it such a further penetration of the lag screw. The lag screw is destroyed. Because such a lag screw at different heights of the key channel can be applied, it is recommended that the cutting edge in the to be arranged essentially parallel to that diameter of the cylinder core, which determines the position of the cross-sectional profile of the key channel.
the locking cylinder 10 is designed in FIG. 1 as a so-called double cylinder, consists of an outer cylinder part 11 and inner cylinder part 12, which act together on an intermediate working cam 13. In the present case, it is sufficient to construct the outer cylinder part 11 consider.
the lock cylinder 10 comprises 11, 12 in both parts a cylinder core 15 with tumblers, here as two-part tumbler pins 16, 17 are formed.
the tumbler pins 16, 17 are in the assembly case under the spring force of compression springs 18 which they towards load the cylinder axis 22.
the cylinder core 15 is in a axial bore of a housing 14 belonging to the locking cylinder 10.
the cylinder core 15 has here designed as radial bores 19 Recordings. Similar recordings are also provided in the housing 14. Take the individual recordings in the cylinder core 15 and housing 14 in each case the two pin parts 16, 17 and the associated compression springs 18 on.
the locking cylinder 50 comprises a profiled key channel 20 which in the area of a core diameter indicated by dash-dotted lines in FIG. 6 21 is arranged and extends along the cylinder axis 22.
the Key channel 20 has a defined cross-sectional profile 23 and is used for Inclusion of a key, not shown, from the front end 24 of the locking cylinder 10 inserted into the outer cylinder section 11 can be. Analog can from the rear end not shown in detail of the broken inner cylinder part 12 shown in FIG. 1.
lag screw 25 can be used to break open the locking cylinder 10 sitting in the door lock.
the locking cylinder 10 could possibly be broken together with the one at 29 front portion of the housing 14 are pulled out. Then the working cam 13 would be accessible and could be used to open the door lock be used by unauthorized persons.
the invention has taken precautions regarding the intrusion tool itself, namely destroy the lag screw 25 and thus the attempted break-in to make impossible.
these hard metal inserts 31 are rod-shaped and consist of two flat plates 31, 32, the plate levels of which extend parallel to the axis 22 of the key channel 20.
the bores 38 are placed symmetrically to the cylinder axis 22 and can have the longitudinal oval profile shown in FIG. 5.
the Both platelet-shaped hard metal inserts 31, 32 consist of sintered Material of high hardness and can be form-fitting in one section insert the holes 38. If necessary, the remaining free spaces can be closed in the milled holes 38 by filler 35.
a third hard metal insert can also be inserted in this front area 36 33 be arranged. As shown in FIG. 6, this consists of a plate-shaped one Segment 33, which with its segment edge 40 on the lower Limitation 39 of the key channel 20 is arranged.
the segment edge 41 can in turn act as a cutting edge, which also corresponds to the one described above Destruction of the lag screw 25 leads.
This segment edge 40 runs perpendicular to the aforementioned cutting edges 30 of the two parallel ones Plate 31, 32.
a secant-like transverse groove 42 is milled, as can be seen from FIGS. 3 and 4.
FIG. 7 shows an enlarged cross section corresponding to FIG. 6 a further cylinder core 15, where a modified key channel 20 'with a curved cross-sectional profile 23' is.
the same reference numerals are used to designate corresponding components as used in the previous embodiment of FIGS. 5 and 6, which is why the same description applies. It is enough just to address the differences.
a hard metal insert 31 'at at least one point with a longitudinal one Groove 44 is provided, in which widened cross-sectional areas 43 of the Key channel 20 'can intervene.
a fourth hard metal insert 34 is in the front Area 36 of the housing 14 is provided.
This hard metal insert 34 has Plate shape and sits in a transverse groove 45, which is below the cylinder core 15 is embedded in the housing 14.
This housing plate 34 protects the tumblers 17 and springs 18 sitting there before axial access of intrusion tools, which at the front end 24 of the housing 14 from Attack lock cylinder 10. There could also be sharp cutting edges be provided that destroy the tool.
