Definitions

  • This invention relates to key operable locks.
  • Conventional locks consist of a lock barrel rotatably received within a lock body.
  • the lock barrel is provided with spring loaded pins.
  • the lock is operable by a key having a key blade, the profile of which co-operates with the spring loaded pins; some lock barrels include locking or side bars which are permitted to move radially inwardly when the pins are properly positioned, allowing the barrel to be rotated to the unlocked position.
  • the present invention provides, in one aspect, a lock barrel assembly operable by a key and adapted to be received within a hollow lock body, the lock barrel assembly comprising a hollow base having a longitudinal axis, at least one disk rotatably supported in the base and extending generally normal to the axis, the or each disk
  • a key engaging means adjacent the aperture and adapted to engage the key so that the key is capable of locating the or each disk at a predetermined position about the longitudinal axis, and at least one locking bar operatively associated with the or each disk and adapted to move radially relative to the longitudinal axis from an outer position to an inner position only when the or each disk is located in its predetermined position by the key.
  • this invention provides a key for operating the lock barrel assembly, the key bearing at least one longitudinal angled track adapted to receive the key engaging means.
  • the hollow lock body into which the lock barrel assembly of the invention may be received may be selected from a wide range, so that the combined lock barrel assembly and hollow lock body may be used as a cylinder lock, cam lock, furniture lock or padlock, inter alia.
  • the lock barrel assembly of the invention may fulfil a wide range of locking functions, simply by changing the selection of the hollow lock body.
  • the lock barrel assembly of the invention is adapted to be rotatable within the hollow lock body when in an unlocked configuration and movement of the or each locking bar to the inner position enables rotation of the lock barrel assembly.
  • the number of disks in the assembly can determine the range of possible combinations. Preferably, two or more disks are used. For simplicity of description, reference will be made to a plurality of disks. However, it is to be understood that the invention is operable with only one disk.
  • the aperture for passage of the key is centrally located in each disk.
  • the key engaging means may take any suitable form; preferably the key engaging means comprises one or more projections extending into the disk aperture.
  • each disk includes a projection or pin adapted to be received in a slot, groove, hole or the like in the locking bar.
  • both the locking bar and the key are cut to the same "code" supplied by computer software.
  • the physical correlation between the locking bar and the key should differ markedly, so that even when placed side by side there is no apparent resemblance. This lack of physical resemblance is possible because the disks comprise transfer or scrambling means linking the locking bar and the key.
  • SUBSTITUTE SHEET key arranges the disks in their predetermined positions, the disks essentially pick up the "code” from the key.
  • the "code” is transferred unchanged to the locking bar, even though the physical configuration of the locking bar is different from that of the key.
  • a disk-like washer may be included in the lock barrel assembly of the invention. Unlike the disks which are rotatably supported within the hollow base, the washer may be stationary until the locking bar has moved to the unlocked position, at which time the washer can be rotated with the whole assembly.
  • the washer has an aperture which is preferably the same as that of the key profile so that the washer can act as a guide for the key and transfer the turning action of the key to the whole assembly. If desired, a plurality of washers may be included in the assembly. The washers may also incorporate eyelets to help prevent "picking", as explained further, below.
  • the disks are rotatably supported within the base. Especially when washers are included, the angle supporting the arc of rotation of the disks may be limited if desired.
  • the assembly has 10 disks arranged in 5 pairs. Between each pair is a washer with a key profile aperture.
  • the key engaging means comprises a projection or pin on each disk, which is lifted in rotation to 36 degrees.
  • the predetermined position which can be occupied by the projection on each disk can be selecte d from seven possibilities, each at 6 degree intervals within the 36 degree arc. Because 10 disks are used, there are more than 280 million combinations available.
  • the disks may be loaded so that the first disk (nearest the plug) can have its projection lying either to the right or to the left. This doubles the number of available combinations.
  • the key of the invention may be circular in cross-section or may have sections removed to give it the required shape, such as that of a keyway.
  • One suitable material for the key is nickel-silver.
  • the key may comprise a key blade which operates the locking assembly and a key head for gripping , in the remainder of this description reference will b e made to the key blade as the operative part of the key.
  • the top of the cross-sectional profile is preferably between 140 degrees and 160 degrees, with the diameter of the blade being between 7 and 8mm.
  • the blade may have a pointed start with a second leading angle up to the point where all cuts start or end.
  • the key blade may have a track or slot machined into it, preferably incorporating programmed angles.
  • the cutting of a key involves the machining of the track or slot into the cylindrical section.
  • This track may be cut by a specially manufactured disposable slot drill with a chamfer cutting edge.
  • the track is cut lengthwise into the key blade and changes radially in angles as it progresses.
  • the cutter should always be oriented towards the centre of the key blade.
  • the cut key blade may feature more than one track. For example, there may be two tracks, with each track adapted to align half the disks.
  • the first track starts at the point of the key, changing direction up to ten times to arrive at the end of the key blade near the key head.
  • the track may end there, or continue over the apex of the key blade to form the second track which runs back to the key point, again changing direction up to twelve times before finishing at the point of the key.
  • the key engaging means e.g., a projection into
  • the position of the track on the key blade, the number and route of the changes in direction and the number of tracks per key blade can be varied, resulting in an extremely large number of possible key profiles.
  • the key of the present invention can be manufactured so that it contains no sharp points or projections and thus will not scratch, or tear clothing, as is the case with many existing keys.
  • the locking bar has two positions. In the first or outer position, the locking bar is preferably retained in a groove in the hollow lock body and while the locking bar is in this position, the lock cannot be opened. The locking bar is retained in this position by external projections or pins on the disks.
  • the disks When the correct key is inserted in the lock barrel assembly, the disks are rotated so that the external projections or pins align with the slots, grooves, holes or the like in the locking bar.
  • the locking bar By turning the key, the locking bar is pushed from its groove in the hollow lock body and meshes with the projections or pins.
  • the lock barrel assembly can rotate, permitting unlocking.
  • SUBSTITUTE SHEET withdrawn from the locking bar assembly until the locking bar is returned to its groove in the hollow lock body.
  • a spring biases the locking bar to the outer position, so that continuous turning of the key will be interrupted by the spring-loaded locking bar dropping back into the groove when the bar is aligned therewith, indicating the position at which the key can be withdrawn.
  • the key withdraws it "scrambles" the disks as they step through the angles in the track or tracks.
  • the locking bar is conveniently made of brass or nickel-silver and may have slots or grooves which extend longitudinally as well as radially. Alternately, as already indicated, holes may be drilled into the locking bar. Preferably, any holes are drilled blind. Even more preferably, extra more shallow holes are drilled - typically, 3 to 4 per locking bar - as an anti-picking feature. These shallow holes will not be capable of meshing with projections on the disks.
  • the locking bar may carry a mixture of slots, grooves and/or holes.
  • the locking bar will contain a large number of operable slots, grooves and/or holes.
  • the locking bar is an important feature of the present invention. It affords a high degree
  • a cover plate may be included in the lock barrel assembly for each locking bar, so that the "code" of grooves, slots or holes therein cannot be observed with the aid of an endoscope, for example.

  • Figure 2 is a perspective view of a key blade suitable for use with the lock assembly of Figure 1;
  • Figure 3 is a longitudinal sectional view of the lock assembly of Figure 1, in assembled form and including a hollow lock body;
  • Figures 4A to 4E illustrate (in cross-section) the lock assembly of Figure 1 (received in a hollow lock body) during operation, so that Figure 4A shows the locked position, Figure 4B illustrates the lock with key inserted, in Figure 4C the lock is in the unlocked position, in Figure 4D the lock barrel has been rotated to the start position; and Figure 4E shows the locked position again; and
  • FIG. 5 illustrates the "anti-pick” option.
  • FIG. 1 there is depicted a lock assembly 10 to be operated by a key having a key blade 11.
  • Lock assembly 10 is adapted to be received in a hollow lock body 15 (refer Figures 3 and 4A to 4E). On the internal surface of lock body 15 is a longitudinally extending groove 14.
  • Assembly 10 is of a generally cylindrical configuration and includes base portion 16 which is C-shaped in transverse cross-section and which has an outer surface which slidably engages the internal surface of lock body 15. Located between the arms of base portion 16 is a locking bar 27. In the locked position, locking bar 27 is received in groove 14. Spring 23 biases locking bar 27 to the outer position.
  • Each disk 17 is of thyroidal configuration so as to provide a central passage 19.
  • Washer 18 is also of thyroidal configuration and provides a
