Definitions

  • the invention relates to a lock cylinder having a housing and a cylinder core mounted in a housing bore with a key channel for inserting a key with zones of harder material arranged on both sides of the key channel near the mouth of the key channel.
  • lock cylinders are known.
  • the lock cylinders are designed as a double lock cylinder and as a single lock cylinder.
  • Essential is a housing in which a housing bore is located.
  • a cylinder core which donate pin tumblers or tumblers locked in tumbler holes.
  • the cylinder core has a key channel. If the appropriate key is inserted into the keyway, the tumblers protruding into the keyway are shifted in such a way that the cylinder core can be turned.
  • hard metal pins with a circular cross-section To avoid a reaming of the cylinder core from the mouth of the key channel forth stuck in both sides of the key channel arranged pockets hard metal pins with a circular cross-section.
  • Lock cylinders used in building entrance doors are subject to high wear as they may be operated a few hundred times a day.
  • the keyway widens as the use progresses. This sooner or later means that the tumblers are no longer sorted correctly by the key and the lock cylinder can no longer be operated properly.
  • the invention is based on the object of specifying easy-to-manufacture, wear-reducing agents.
  • each claim represents an independent solution to the problem and can be combined with any other claim.
  • the zones of harder material which hitherto had the task of increasing burglary protection, are arranged so close to the key channel that they form a region of the keyway wall from the beginning or already after a small, wear-related material removal of the wall of the keyway so that the key broadside slides along the zone of harder material.
  • a wear-related material removal is here considered such material removal, which does not cause the lock cylinder is unusable. It is a material removal, which is less than about one fifth of the width of the keyway or the distance between the two zones of harder material to each other. Since this zone of harder material is significantly more resistant to abrasion than the brass material of the cylinder core, the wear is reduced to a considerable extent.
  • the zones of harder material may consist of inserts as in the prior art. These preferably have the form of platelets. They are elongated in the extension direction of the key channel and are non-rotatably in their associated pockets. Preferably they are form filling in the pockets of the cylinder core.
  • the pockets extend transversely to the extension direction of the keyway and in such a way that the opening of the pockets is closed by the cylinder bore in the cylinder bore in the housing bore of the housing are.
  • the platelets may be made of hard metal or another, for example, hardened material, in particular steel.
  • the flanks facing the mouth of the zones of harder material, ie the platelets stuck in the pockets, are rounded.
  • One or more grooves in particular a guide groove of the key channel, can lie in recesses of the plate.
  • the groove bases of the profile grooves and guide grooves have a distance of a few tenths of a millimeter from the broad side wall of the underlying ones
  • Carbide tips The material web between the groove base and side wall of the hard metal plate but also needs to be only a few hundredths of a millimeter. At least after a slight wear-related material spacing, a partial section of a profile groove, and in particular the groove base, is formed by the surface of the hard metal plate.
  • the carbide tip has a cross-sectional outline that does not form corners. Both the mouth, as well as the pointing in the opposite direction narrow side walls of the hard metal plate go without kinks in the opposite side walls over.
  • the longitudinal extension of the hard metal chip is preferably twice as large as the transverse extent with respect to the extension direction of the keyway.
  • the side wall of the hard metal chip, which faces the key channel may have one or more groove-shaped recesses which correspond to profile grooves of the key channel.
  • the distance of the mutually facing side walls of the hard metal plates, which run parallel to each other, may be slightly smaller than the distance of the imaginary parallel planes thereto, in which lie the groove bottom of the deepest grooves of the respective broad side of the keyway.
  • FIG. 2 is a plan view of the lock cylinder with the mouth region of the keyway cut open;
  • FIG. 5 is a view according to FIG. 4, but from a different angle
  • Fig. 8 is a view according to FIG. 6, but after wear-induced abrasion of the walls of the keyway, and
  • Fig. 9 is a view according to FIG. 7 after wear-induced abrasion of the two walls of the keyway.
  • the lock cylinder 1 is a double lock cylinder. He has a housing made of brass 2, which supports a closing member 13 between its two housing halves. A cylinder core 4 is mounted in a housing bore 3. The outer diameter of the cylinder core 4 substantially corresponds to the inner diameter of the housing bore 3, so that the cylinder core 4 can be rotated in the housing bore 3. To the cylindrical surface of the cylinder core 4 open pockets 10, in which hard metal plate 7 form filling are plugged in. Through the center of the cylinder core 4 extends a keyway 5 for insertion of a key. The keyway 5 extends between the two hard metal platelets 7.
  • the hard metal platelets 7 form facing Breitdonwandept 7 'from which are only a few tenths, preferably a few hundredths of a millimeter from the wall 8 of the keyway 5 spaced.
  • the cylinder core 4 has a front collar 12 in the region of the mouth 6 of the key channel 5.
  • the narrow side wall 7 "of the hard metal blade 7 facing the mouth-side end side of the cylinder core 4 is rounded and lies in the region of an end collar 12 of the cylinder core 4.
  • the cross-sectional outline contour of the hard metal plate 7 is that of an oval, and two semicircular arc sections 7 "lying opposite one another extend into broad side walls 7 'extending parallel to one another.
  • the keyway 5 has a plurality of extending in the direction of extension of the keyway 5 guide grooves 9 and 9 'profile grooves.
  • the key not shown, has correspondingly formed ribs which are guided in these grooves 9, 9 '.
  • the hard metal flakes 7 have groove-shaped recesses 11 in the broad side walls 7 'facing the key channel 5.
  • a guide groove 9 of the key channel 5 protrudes into a recess 11 of the hard metal flake 7.
  • the groove bottom of the profile groove 9 ' is only a few tenths, preferably only a few hundredths of a millimeter away from the side wall 7' of the associated hard metal plate 7.
  • the width of the key channel is defined as the distance between two mutually parallel planes, in each of which the deepest groove of the two walls 8 of the key channel 5 lies, then the width of the key channel can be defined. nals 9 be greater than the distance between the two broad sides 7 'of the hard metal plate. 7
  • At least the material thickness between the bottom of a deepest profile groove 9, 9 'and the underlying side wall 7' of the hard metal plate 7 is so small that it can be worn off in the course of wear, without the lock cylinder losing its functionality.
  • the wall 8 of the keyway 5 is at least partially formed by a side wall 7 'of the hard metal plate 7. It proves to be advantageous that the carbide tips 7 in key displacement direction no sharp edges, but curves. As a result, no abrasion occurs on the ribs of the key, although the latter slide along the side walls 7 'of the cemented carbide flakes.
  • the hard metal platelets 7 can be loose, that is to say un adhesively bonded in the pockets 10, since they are closed by the inner wall of the housing bore 3 in the assembled state. But it is also envisaged to keep the hard metal plate 7 in a press fit in the pockets 10.
  • a core bore 14 in which a core pin, not shown, is guided extends as far as the side wall 7 'of the associated hard metal plate 7.
  • the mutually parallel pockets 10 can be milled with a router. This is done before or after the clearing of the keyway 5. Since the guide groove 9 cuts the pocket wall, there is a window at the rear of which the bottom 11 'of the recess 11 is located. In the course of a wear-related abrasion of the wall 8 of the key channel, a rib of a key can slide along the bottom 11 'of the recess 11.
  • the guide groove 9 serves for the correct guidance of the key Key in the key channel 5.
  • the key has a corresponding guide rib.
