Definitions

the invention relates to a rotary lock cylinder for a security lock, with a driver mounted between two cylinder parts for actuating a bolt and with a web that firmly connects the two cylinder parts to one another.
Such a rotary lock cylinder has become known in the prior art, for example from CH-A-626 679.
the web connecting the two cylinder parts serves on the one hand to stiffen the cylinder housing and, on the other hand, contains a threaded hole for the forend screw in its reinforced central part.
a rope made of spring steel wire is soldered to the web disclosed in CH-A-679 169, which does not break even under constant bending stress.
the manufacture of this bridge is very complex.
the invention has for its object to provide a rotary lock cylinder of the type mentioned, which offers greater security in particular against attempts to tear it off and which is nevertheless inexpensive to manufacture.
a central part of the web has an attached tube piece which has a recess for the driver at the top, the tube piece engaging around a rod-shaped body of the web.
the tubular piece placed on the rod-shaped body of the web stabilizes it in its central part and thus in the area of the faceplate screw bore.
the deflection in the area of the faceplate screw bore is significantly reduced. By reducing the deflection, a fatigue fracture in the area of the faceplate screw hole is very unlikely or would require a very long load.
the pipe piece is made of chrome nickel steel, for example, and can for example, can be produced very simply as a section of a tube.
the security against tear-off attempts in the rotary lock cylinder according to the invention is, according to a further development, significantly higher if the web is only pinned to the outside at its ends with the cylinder parts. If an attempt is made to break the web by bending stress, the web is bent in a much longer area than before. Accordingly, the bend is less and the time until a fatigue break is reached is correspondingly longer.
the recess in the tube piece has a plurality of slots and the driver has corresponding tabs which pass through the slots when the driver is rotated.
the recess of the pipe section can thus be kept very short.
the pipe section can also grip around the rod-shaped body between two slots and thus stabilize it.
the rotary lock cylinder 1 shown in FIG. 1 has two cylinder parts 2 and 3 which are known per se and each comprise a cylinder housing 22 or 23.
the cylinder parts 2 and 3 are firmly connected to one another with a web 10.
This web 10 has a rod-shaped body 12, which with its two ends 21 each in a corresponding Recess 20 of the housing 22 and 23 engages. These ends 21 are each firmly anchored in the housing part 2 or 3 by a pin 17 inserted into a cylinder bag 4 or 5 from below.
two vertically running bores 16 are provided in the body 12 at the greatest possible distance from one another.
a carrier 6 with a beard 7 is mounted above the web 10 in the locking cylinder 1. When a rotor, not shown here, is released for rotation, the driver 6 can be rotated in a manner known per se to actuate a lock bolt.
a tubular piece 11 is placed on the rod-shaped body 12 and has a passage 13 corresponding to the cross section of the body 12.
FIG. 3 shows the body 12 with the tube piece 11 placed approximately in the center.
a threaded bore 18 is machined into the tube piece 11 and the body 12 for the forend screw not shown here.
the pipe section 11 can be fixed to the body with cross pins 19.
the body 12 and the pipe section 11 can also be soldered to one another. Both parts are preferably made of stainless steel. However, other suitable materials are also conceivable.
a plurality of slots 14 are machined at the top, which are arranged parallel to one another and are open at the top and on the side.
the beard 7 has tabs 8 which can pass through the slots 14 with little play when the driver 6 is rotated.
Areas 15 between and next to the Slits 14 encompass the rod-shaped body 12 and stabilize it, so that the body 12 is only slightly or not bent in the area of the faceplate screw bore 18 during a bending test.
the pipe section 11 has comparatively large side surfaces 24 which abut the inner sides 25 and 26 of the housings 22 and 23, respectively. The housings 22 and 23 are thus supported on the pipe section 11 over a comparatively large area and are thereby additionally stabilized. This support also makes it difficult to bend the web 10.
Figures 6 to 8 show the driver 6, which can be designed with the exception of the beard 7 as is generally known.
An embodiment is also conceivable in which the beard 7 is not provided with slots 9 and the tube piece 11 has only one slot 14 in the width of the beard 7.
the pipe section 11 then encompasses the body 12 on the left and right of the single recess.
