Definitions

  • the invention relates to a cylinder lock with drill protection.
  • each lock housing is provided at the underside with a downwardly open, rectangular slot in which the bridge is receivable.
  • the drill protection is formed by a loose part which in that publication is designated with the reference numeral 11.
  • a drill protection is especially important for protection of the lock against burglars who with a drill try to drill through the bottom area of the lock, so that the connection of the bridge with the lock housing is damaged and the lock housing can thereupon be pulled from the bridge with force.
  • NL 6 711 284 A NL'284
  • FR 2 689 558 A1 FR'558
  • NL'284 discloses a cylinder lock with drill protection.
  • the lock includes a first lock housing and a second lock housing as well as a bridge which are integrally formed in one piece.
  • the drill protection comprises steel balls which are placed inside the lock pin springs.
  • FR'558 discloses a barrel lock in two sections, each with a stator and a rotor, linked by a bridge.
  • chambers are provided in which pins of hard material e.g. tungsten carbide are accommodated which form a sabotage protection.
  • a second way of unauthorized keyless opening of a lock involves so-called lock picking. This has even become a sport, for which also clubs exist and tools are sold. A description of a lock picking tool is given, for example, in US-5 956 984 B1 .
  • a lock pin with improved protection against lock picking is described in DE 1 122 866 B1 .
  • the known lock pin comprises a shank, a head which is broadened with respect to the shank and which forms a first lock pin end, at least one loose ring which extends around the shank with play, and a retaining ring which is fixedly connected with the shank and forms a second lock pin end.
  • a drawback of the drill protection known from EP '305 is that assembling the drill protection together with the bridge and the lock housing is hard because three loose parts need to be put together simultaneously. Also the part forming the drill protection is a special part having a special shape. Such a part is costly to manufacture, in particular also because the material should be hardened and so is difficult to machine.
  • the invention contemplates a cylinder lock having the above-described properties without the just-described drawbacks. More particularly, the invention contemplates a cylinder lock whose drill protection can be implemented more inexpensively and the assembly of which is simpler.
  • the invention provides a cylinder lock according to claim 1. More particularly, the lock described in the background section is characterized according to the invention in that
  • Balls of hardened steel are a standard commercially available commodity. They are produced in large numbers for ball bearings and for that reason are available at a relatively low price.
  • the bridge is provided with a chamber for taking up the ball, assembling a lock is simpler than in the case of the prior art lock with drill protection. This is because first the balls are placed in the chambers in the bridge. Thereupon, the axial end parts of the bridge can be moved into the two lock housings. After this, only the bridge needs to be fixed with respect to the lock housings, which will be described in more detail hereinafter with reference to an exemplary embodiment.
  • the cross pins take care of a very strong connection between the bridge and the lock housings. Certainly when the cross pins are also made of hardened steel, it is virtually impossible to sabotage the cylinder lock by means of a drill.
  • the drill protection provided with balls and the cross pins provides a particularly secure cylinder lock that meets the highest security class standard.
  • Figures 1-5 show an example of a cylinder lock in which various embodiments as described in the subclaims are embodied. It is noted that the embodiments can also be applied independently of each other and that the invention is not limited to the examples shown in the figures.
  • various embodiments will be described, reference being made to the figures with the help of reference numerals. The reference numerals are used herein for clarification but have no limiting effect. An embodiment may also be implemented in a different manner than represented in the example that is shown in the figures.
  • the invention provides a cylinder lock 10 comprising a first lock housing 12 having a substantially constant circumferential contour extending in an axial direction, with a lock cylinder 14 included in the lock housing 12. Further, the cylinder lock 10 comprises a second lock housing 16 having a substantially constant circumferential contour extending in an axial direction, in which either a second lock cylinder (not shown) is included or an operating knob assembly. A description of an example of such an operating knob assembly is given in Netherlands patent application NL-2012477 .
  • the circumferential contour of the second lock housing 16 corresponds to the circumferential contour of the first lock housing 12 and the circumferential contours of the two lock housings 12, 16 extend in line with each other.
  • the cylinder lock 10 is further provided with a carrier 20 which is provided with a carrier cam 22 and which is included between the first and the second lock housing 12, 16.
  • the carrier 20 is rotatable relative to the first and the second lock housing 12, 16 and is positionable in a first position in which the carrier cam 22 is in a recess 24 between the first and the second lock housing 12, 16. In that first position, moreover, the carrier cam 22, viewed in axial direction of the lock 10, is within the circumferential contours of the two lock housings 12, 16. Through rotation, the carrier 20 is positionable in a second position in which the carrier cam 22, viewed in axial direction, extends outside the circumferential contours.
  • the cylinder lock 10 is further provided with a bridge 26, which connects the first lock housing 12 with the second lock housing 16.
  • the cylinder lock 10 is provided with a drill protection which is included at least in the first lock housing 12 near an axial end 12a of the first lock housing 12, this axial end 12a being remote from the second lock housing 16.
  • a drill protection which is included at least in the first lock housing 12 near an axial end 12a of the first lock housing 12, this axial end 12a being remote from the second lock housing 16.
  • the cylinder lock 10 is characterized in that the drill protection is implemented as a ball 28 from hardened steel, while the bridge 26, near an axial end thereof that is in a bridge bore 30 in the first lock housing 12, is provided with a chamber 32 in which the ball 28 is received.
  • Such a drill protection is simple to assemble and can be implemented inexpensively because hard steel balls are obtainable at low cost price and assembly is simple.
  • the second lock housing 16 may be provided with a drill protection.
  • This drill protection can also be implemented as a ball 34 from hardened steel, while the bridge 26, near an axial end thereof that is in a bridge bore 36 in the second lock housing 16, is provided with a chamber 38 in which the ball 34 is received.
  • the bridge 26 comprises a substantially cylindrical central part 40 of a first diameter.
  • the central part 40 has a first and a second axial end 40a, 40b. With the first axial end 40a, a first, substantially cylindrical end part 42 is connected. With the second axial end 40b, a second, substantially cylindrical end part 44 is connected.
  • the end parts 42, 44 and the central part 40 are implemented as a single, integral component.
  • the substantially cylindrical central part 40 and the two end parts 42, 44 are positioned coaxially with respect to each other and therefore have a common axis Lb.
  • a first plane V which includes the axis Lb extends in use in a vertical direction.
  • a second plane H which includes the axis Lb extends in use in a horizontal direction.
  • the central part 40 may be provided, on opposite sides of the center thereof, with a bore 84, 86.
  • One bore 84 may be associated with a threaded bore 88 in the first lock housing 12.
  • the other bore 86 may be associated with a threaded bore (not shown) in the second lock housing 16.
  • the cylinder lock 10 in this embodiment may be provided with two bolts 80, 82.
  • a first 80 of the two bolts 80, 82, in the assembled condition of the cylinder lock 10, extends through one bore 84 and is fastened in the threaded bore 88 in the first lock housing 12.
  • the other 82 of the two bolts 80, 82, in assembled condition of the cylinder lock 10, extends through the other bore 86 and is fastened in the threaded bore in the second lock housing 16.
  • Each end part 42, 44 has a cylindrical surface or superficies.
  • a recess 46, 48 is provided, having a, viewed in a direction perpendicular to the first plane V, substantially circular segment-shaped contour.
  • a substantially cylindrical cross pin 50, 52 is associated, as well as a cross bore 54, 56 in the lock housing 12, 16 associated with the respective end part 42, 44.
  • the cross pins 50, 52 take care of a very strong connection between the bridge 26 and the lock housings 12, 16. Certainly when the cross pins 50, 52 are also made of hardened steel, it is virtually impossible to sabotage the cylinder lock 10 by means of a drill.
  • the drill protection provided with balls 28, 34, and the cross pins 50, 52 provide a particularly secure cylinder lock 10 that meets the highest security class standard.
  • a central ridge 58, 60 may be provided which is on the side of the recess 46, 48 proximal to the central part 40.
  • the substantially cylindrical cross pin 50, 52 may then be provided with a central groove 62, 64 in which in assembled condition of the cylinder lock 10 the central ridge 58, 60 is received.
  • This central ridge 58, 60 prevents the cross pin 50, 52 possibly falling out of the lock housing 12, 16 when the bridge 26 has taken up its final position in the lock housings 12, 16.
  • Assembly proceeds as follows: first, an end part 42, 44 is slipped partly into the bridge bore 30, 36 of the lock housing 12, 16 associated with the end part 42, 44. Thereupon the cross pin 50, 52 is slipped into cross bore 54, 56. After this, the end parts 42, 44 are slipped deeper into the bridge bores 30, 36, so that the central ridge 58, 60 is received in the central groove 62, 64 of the corresponding cross pin 50, 52. Finally, with the aid of the bolts 80, 82, the bridge 26 and the lock housings 12, 16 are connected with each other. When a burglar tries to break the lock housing 12 loose from the bridge 26 with brute force, he must break not only the bolt 80 but also the cross pin 50. Since the cross pin 50 may be made of hardened, high-grade material, this is virtually impossible and the attempts of the burglar will fail.
  • each end part 42, 44 can include an above-mentioned chamber 32, 38 for receiving an above-mentioned ball 28, 34.
  • the chamber 32, 38 in an end part 42, 44 the ball 28, 34 in an assembled condition of the cylinder lock 10 is always confined in the chamber 32, 38 because the access opening of the chamber 32, 38 is closed off by the associated lock housing 12, 16.
  • the chamber 32, 38 in an end part 42, 44 may be situated under the recess 46, 48 in the cylindrical surface of the end part 42, 44.
  • the room that the ball 28, 34 has in the chamber 32, 38 is somewhat smaller, so that the possibilities of movement of the ball 28, 34 are somewhat more limited. This makes the chances of successfully executing a drill attack even slimmer.
  • each end pin 42, 44 may be provided with a circumferential groove 66, 68 which is associated with a clip.
  • An example of this embodiment is shown in Figures 8 and 9 .
  • Each lock housing may then be provided with a clip groove in which the clip is receivable. In an assembled condition, the clip may be received in the clip groove in the lock housing 12, 16 and engages a circumferential groove 66, 68 of the associated end pin 42, 44 which is received in the respective lock housing 12, 16.
  • the clips and clip grooves are not shown in the drawings. Use of such clips and clip grooves, however, is for instance known from WO2006/042753 A1 and for an example of the clips and clip grooves, reference is made to that publication.
  • the central part 40 may be provided with a central bore 78 which extends perpendicular to the first plane V and which is threaded.
  • the cylinder lock can be fixed in a door (not shown) by means of a bolt which engages the central bore 78.
  • the cylinder lock comprises a lock pin 200 which is intended in particular to prevent the unauthorized opening of a cylinder lock 10 by lock picking, or at least to make this as difficult as possible.
  • FIG. 10 An example of a lock pin 200 is shown in detail in Figures 10 and 11 . Also in Figures 2 and 5 , the example of the lock pin 200 of Figures 10 and 11 is shown. It is to be noted that the new bridge 26 with the new drill protection can also be applied in a cylinder lock 10 that is provided with conventional lock pins.
  • the anti-lockpicking lock pin 200 has in the most general terms a shank 206 and head 208 which is broadened with respect to the shank 206 and which forms a second lock pin end 204. Further, the lock pin 200 is provided with at least one loose ring 210, 210', 210" which extends around the shank 206 with play. Further, the lock pin 200 has a retaining ring 212 which is fixedly connected with the shank 206 and which forms a first lock pin end 202.
  • the loose rings 210, 210', 210" make lock picking virtually impossible, presumably because the fixing of such a ring 210, 210', 210" during lock picking does not yet lead to the axial fixation of the shank 206 and the head 208, connected thereto, of the lock pin 200. In any case, it appears from practical tests that the lock pin 200 makes lock picking virtually impossible.
  • lock pins 200 with, respectively, two, one, three, and one loose ring or rings 210, 210', 210".
  • the shank 206 may be provided, near the first lock pin end 202, with a reduced cylindrical part 206' whose length Lj substantially corresponds to the height H1 of the retaining ring 212.
  • a central axial central bore 214 may be provided in the first end 202.
  • the retaining ring 212 may be provided with a central bore 216 in which the reduced cylindrical part 206' is fittingly received.
  • An end of the central bore 216 of the retaining ring 212 that is remote from the head 208 may be provided with a chamfer 218.
  • the free end of the reduced cylindrical part 206' can be widened by plastic deformation, so that the widened part 220 thereof is received in the chamfer 218.
  • lock pin 200 may be provided with one to six loose rings 210, 210', 210", while the length Ls of the non-reduced part of the shank 206 is somewhat greater than the sum of the heights H2 of the loose rings 210, 210', 210" placed on the shank 206, so that the loose rings 210, 210', 210" are arranged on the shank 206 with some play.
  • the presence of play is important to obtain the desired effect, viz., efficiently preventing lock picking.
