Definitions
- This invention relates to a mechanical lock system using cards.
- United States Patent Specification No. 4,627,252 discloses a card operated lock using a set of plates arranged to directly receive a card with notches selectively removed in the end. This lock is only operable from one side, and re-keying involves rearranging the plates. The user card directly engages the lock mechanism. This arrangement only allows for one possible position for each ball or ring, and does not allow for master keying hierarchies.
- French Patent Specification No. 1,163,526 discloses a simple mechanical lock arrangement comprising a series of spring loaded locking tumblers which are capable of being displaced independently of one another in a plane perpendicular to that in which the slide bolt is displaced.
- the mechanism is operable by use of a key featuring a series of grooves of varying depths, with one groove provided for each tumbler. Upon insertion of the key the tumblers undergo varying displacements, with the correct combination of displacements leading to the unlocking of the mechanism.
- this mechanical lock arrangement does not allow for the re-keying of the lock mechanism.
- United States Patent Specification No. 4,587,815 describes a lock for use with a sheet key having a plurality of holes therethrough.
- the lock comprises a plurality of plates which are independently slidable along a path generally transverse relative to the key. Each plate has a pin on its edge facing the key and an aperture therein. When the plates are moved towards the key, selected pins pass through corresponding holes. An elongate opening through all the plates is formed to indicate an unlocked position if the correct key has been inserted.
- the present invention is directed at a lock mechanism operable using a user card the user card having a pattern of openings therethrough, and the lock mechanism comprising a plurality of generally parallel plates slidable relative to each other, with at least some of the plates having projections for insertion through the openings in the user card, and means for enabling release of the mechanism.
- a combination card corresponding to the user card is provided to define a combination profile
- the openings in the user card are in the form of slots
- the means for enabling release comprise means for engaging a combination profile
- the mechanism is operable to slide the plates towards the user card in a direction perpendicular to its plane and insert projections into respective slots, the lock mechanism being releasable only if the user card enables the plates to be moved such that the means for engaging a combination profile are correctly positioned to engage the profile defined by the combination card, and the combination card being replaceable to re-key the lock mechanism.
- the invention also provides a user card for use in a lock mechanism as defined above, the card having a plurality of substantially rectangular slots therethrough, the longitudinal axes of the slots being generally perpendicular to the direction of insertion of the card, and the depth of insertion of projections therein being dependent on the length of the slots.
- the lock mechanism 15 is based on body 80.
- the body 80 includes a number of pins and recesses, whose functions will be described in more detail below, and provides the externally visible surfaces of the lock.
- Body 80 supports plate 50 via pins 88, 89, 101-104 and respective recesses 55, 54, 115, 114 and 116. It can be seen that plate 50 in the assembled position is enabled to slide vertically relative to body 80. Spring 92 retains the plate 50 in position via pins 102, 103.
- Body 80 also supports lock plate assembly 30, via pins 86, 87 and recesses 33, 34.
- lock plate assembly 30 comprises a series of similar plates 31 stacked in a laminar fashion and enabled to slide horizontally note the movement available between pins 86, 87 and recesses 33, 34.
- Body 80 also includes recess 84 for insertion of combination card 40.
- Combination card 40 includes a shaped pattern of recesses and protrusions 41 (see Figure 2) with widths matching the thickness of plates 31 so that the plates 31 are pushed horizontally into a pattern defined by combination card 40.
- Spring 91 retained by pin 105 maintains the plates in position when no combination key 40 is in place.
- Plate 50 supports, via pins 51 and 52, and recesses 23, 24, key plate assembly 20.
- Pin 90 also extend from body 80 through slot 58 to support and atign the plate assembly 20.
- the key plate assembly 20 comprises a set of plates arranged similarly to lock plate assembly 30, and of the same thickness but of a different cross-sectional shape.
- Bolt 70 rests on plate 50 and is secured in the locked or open position by pin 57. Spring 92 retains the bolt 70 in position. Bolt 70 passes through recess 83 in body 80. Bolt 70 includes recesses 72, 73 in its upper surface which define the open and locked positions respectively. Pin 81 and slot 74 provide support and guidance for bolt 70. Opening 53 allows for movement once user card 10 is inserted in slot 85.
- user card 10 includes various slots 11, the distance from the end 13 of each of which is predetermined, while the sideways displacement defines a particular key combination from the variety available.
- slot combinations 11, 12 at each end are mirror images to facilitate locking and unlocking from either side of the door.
- the thereby re-aligned plates 21 accordingly define a specific pattern in the protruding tabs 25 which extend upwardly from the plates.
- the combination key 40 when inserted displaces the plates 31 so as to create a specific pattern of recesses 32 in the base of the lock plate assembly 30.
- each combination card 40 there is a corresponding pattern of plates formed, and hence a corresponding pattern of slots 11 in user card 10.
- FIG 3 shows in detail the other lock components. Referring also to Figure 2, the operation of the lock will be described.
- Cam means 60 is received in recesses 56 and 82 (not shown) via seat 61. As cam means 60 is rotated clockwise, it raises plate 50 via cam 62 and hence key plate assembly 20 towards lock plate assembly 30. It also lifts pin 57 in slot 72. As the key plate assembly 20 is moved up, the lugs 22 are pushed into slots 12 of the user card 10 and hence are shifted horizontally in a pattern corresponding to the key. As cam means 60 is rotated towards the top position, tabs 25 and recesses 32 approach each other. If they match, and tabs 25 are received in recesses 32, then pin 57 is lifted clear of slot 72, the cam acts on recess 71, and the bolt 70 moves to the locked position. On further rotation, pin 57 enters slot 73 and so retains bolt 70 in the locked or unlocked position.
- spring means ensures that key plates 21 return to the aligned position as they are lowered, so as to not retain a record of the correct alignment of the plates for opening.
- FIG. 4 An example of a possible external configuration is shown in Figure 4.
- Combination card 40 has already been placed in opening 84.
- User card 10 is inserted into slot 85, and knob 63 rotated. If the correct key is inserted, it will rotate from locked to unlocked or vice-versa: otherwise, it will only rotate part-way and will not move bolt 75.
- FIG. 5 to 8 Illustrated in Figures 5 to 8 is a lock mechanism which utilises a set plate configuration, wherein the combination can only be changed by replacing one or more plates. It uses a preferred stepped plate arrangement for engaging the card.
- the lock comprises a lock body 202 having pins 201, 203 located thereon.
- a lever slide plate 214 which slides up and down and is located by pins 201,203. (Slide plate 214 is also visible in Figure 8.)
- the lever slide plate 214 has attached to it, by means of pins 199, 205, 219, a series of card engaging means in the form of slide plates 206. As illustrated in Figure 7 and Figure 8, the slide plates 206 are located in staggered formation as this allows a greater distance between the holes 222 on card 221, illustrated in Figure 6.
- Slide plates 206 have a stepped portion 209 on an upper portion thereof, whilst at a middle or lower portion there are lock gates 207, one on either end of slide plates 206. Having a gate 207 on each end allows the slide plates 206 to be reversible , and so they can be arranged in alternate arrangement as illustrated in Figure 7 with steps portions 209 on the left and right hand side.
- the slide plates 206 are mounted on pins 199, 205, 219 which are attached to plate 4 , and as illustrated in Figure 5 a spring 208 biases slide plates 206 relative to pins 201,203 on lever slide plate 214.
- the locking mechanism also includes a bolt plate 210 having a gate post or pin 211.
- the bolt plate 210 is locked either in the open or in the closed position when the gates 207 are not aligned.
- the body of the lock mechanism includes a slot 215 for the insertion of card 221 (illustrated in Figure 6).
- a cam shaft 60 which ( as in the first embodiment) has a dual purpose of pushing the slide plates in an upward direction and once the gates 207 are aligned, so as to open channel 230, moving the bolt plate 210 and hence bolt 211 to the locked or unlocked position. These actions are performed in this arrangement when the card 221 having the correct combination is inserted in the slot 215.
- the cam shaft 60 is of a shape to engage recesses 228, 224 in the plates 214 and 210, through recess 225 in lock body 202.
- a card 221 is inserted in slot 215.
- the card is of a reversible nature and the lock can be opened from either side.
- the card has holes 222, preferably of a square or rectangular nature, which when correctly positioned allow the stepped portion 209 of each slide plate 206 to move in an upward direction until such time as a step of stepped portion 209 cannot pass through the hole 222 in card 221.
- the length of the slot or hole 222 in the card 221 determines the length of travel in the vertical direction which the slide plate 206 will move.
- the slide plate 214 continues in an upward direction compressing respective springs 208 of those slide plates 206 which can move no further.
- Slide plates 206 that can move will continue to do so until such time as a corresponding step engages the side of the hole 222 on card 221.
- gates 207 on adjacent slide plates 206 are in an aligned orientation so as to form channel 230, allowing the gate post 211 on bolt plate 210 to move into the gate 207.
- a single turn of shaft 60 e.g. by a mating knob which can only occur when user card 221 is in its correct position will open or unlock the lock.
- the gate post 211 is located inside channel 230 of slide plate 206 , if so desired, the user card 221 can be removed with the locking mechanism in the secured unlocked position.
- the user card 221 as illustrated in Figure 6 preferably also contains a magnetic strip 223 for use in those situations where other information may be required, or possibly other locking mechanisms can be associated with the mechanical locking mechanism of the present invention.
- the arrangement of holes 222 allows the presence of a magnetic strip 223 without diminishing the possible number of combinations.
- Possible variations include the provision of latching means to generally operate the lock, and deadlocking means to make the bolt plate 210 go through a double length movement in order to ensure deadlocking of the lock.
- Combinations of these locks whilst not being variable can be changed by changing the combination of slide plates 206 .
- the locking mechanism has preferably 7 or 8 slide plates 206.
- the locking mechanism can operate with any number of slide plates 206, however, a lower number will result in a decrease in the number of combinations which are possible and thus a reduction in security level.
- One of the advantages of the present invention is that the card is not worn and the lock mechanism is not worn by the action of inserting the card. Wearing occurs only when the cam shaft 60 is turned, and this does not transfer any force to the card.
- the second embodiment of the invention allows for use of the stepped plate arrangement, together with a simple re-keying procedure using a combination card.
- lock 220 including a setting or combination card carriage 247 supported via pins 253 and 254 received in recesses 263, 264.
- Cam means 246 is defined in carriage 247.
- Combination card receiving means 243 is arranged on carriage 247, and is adapted to receive combination card 244.
- Plate assembly 249 comprises a number of slide plates 242 having a predefined stepwise configuration 209 on or in an upper surface thereof, as has been described in relation to the second embodiment.
- each slide plate 242 also includes, remote from the stepwise configured upper surface, a tab or lug 245 engageable in a corresponding slot 256 in combination card receiving means 243.
- Combination card 244 includes a number of slots or holes 265 of predetermined configuration to match the configuration of the number of lugs 245 on slide plates 242.
- User card 221 as previously described includes recesses 222 , which may be of any desired configuration, but are preferably square or rectangular, which when correctly positioned with respect to the step portions 209 of slide plates 242 allow the step portions to move in an upward direction until such time as a step of the step portion cannot progress any further.
- Biasing means 248 in the form of a spring biases the combination card receiving means 243 in the direction of slide plates 242 and if the combination card 244 corresponding to the user card 221 is present in the receiving means 243, the lock can be opened.
- Figure 10 provides a depiction of a preferred external lock configuration, similar to Figure 4.
- Shutter 255 is slidable with respect to the body of lock 220, and provides added security in that it acts as a barrier to improper insertion of a combination card 244.
- the shutter 255 is operable and openable by user card 221 to allow ingress of a combination card 244 into receiving means 243 only if the correct user card 221 is inserted into user card slot 85.
- Latch mechanism 75 may be of any suitable type .
- User card 221 is inserted into slot 85 and the cam means 246 is rotated by knob 63, preferably in an anti-clockwise direction.
- the step portions 209 of slide plates 242 pass upwardly through the recesses 222 in user card 221, causing the slide plates 242 to re-align horizontally.
- the re-aligned plate assembly 249 accordingly defines a specific pattern of the lugs 245 on slide plates 242 .
- the user card 221 thus facilitates the formation of a desired lug combination.
- combination card 244 has a predefined punched pattern therein, which is configured to align with the combination formed by the lugs 245 as the cam means 246 is rotated further.
- Spring 248 biases the card receiving means 243 towards the lugs 245 if the correct combination card 244 is inserted into the receiver 243. On matching, the lugs 245 will pass through the card 244, allowing the cam means 246 to continue to rotate and to thereby facilitate unlocking of the lock.
- Figure 11 shows a lock mechanism 300 generally similar to the embodiment of Figure 9, utilising user cards 221 and combination cards 244 of similiar type.
- the slide plate assembly 360 comprises alternating left 362 and right 361 slide plates with upper stepped projections 309.
- the front slide plate 369 and rear plate 368 are slightly different in their construction from the other plates as will be discussed below (see Figure 15).
- the combination assembly 301 comprises a carrier 308 for receiving combination card 244, recesses 306, 307 receiving corresponding pins 302, 303, teeth 305 and projection 304.
- Pins 302, 303 are part of the body, which is not shown so as to enhance clarity.
- Main plate assembly 350 is arranged so as to travel up and down relative to the combination assembly 301 and slide plate assembly 360, and includes cam device 320.
- Lock plate 340 lies parallel to plate assembly 350, and includes teeth 342 corresponding to teeth 305.
- Cam device 320 (see Figure 16) includes a channel 328 for receiving a handle, cams 322 and 324 for raising and lowering respectively plate assembly 350, and cams 323 and 321 for raising and lowering respectively the lock plate assembly.
- combination card 244 and user card 221 are correctly inserted into their respective positions, and that they must be a corresponding pair.
- rotating cam device 320 initially causes cam 322 to engage fans 352 (the left side is not visible) which engage teeth 351 and start to lift main plate assembly 350. This starts to lift slide plate assembly 360 via compressible fingers 363 on each slide plate, and rollers 364. It will be understood that (after some travel) step portions 309 of slide plates 361, 362 enter the slots of user card 221 as far as possible, and that each slide plate then ceases further upward motion. This causes lugs 367 on the (as drawn) right sides on the slide plates 361, 362 to form a specific pattern.
- cam 323 engages the lock plate 340 and moves it up and to the left. This also moves, via spring 345, the combination assembly 301.
- the combination assembly 301 is moving left and up at the same time as the slide plates 361, 362 are engaging user card 221 and forming a pattern of lugs 367. If the pattern of lugs 367 matches the pattern of slots 265 in the combination card, both parts continue their relative travel, the lugs 367 enter the slots 265 in the combination card, and the lock completes its movement to the unlocked position.
- the slide plates 361, 362 and as much as possible of the rest of the mechanism are formed from a relatively rigid plastics material such as perspex.
- the cam device 320, and lock-operative parts of the lock plate 340 and combination assembly 301 are preferably formed from a metal alloy so as to provide break resistance.
- means are provided with the knob (not shown) for turning cam device 320 such that excessive force results in slippage of the knob, rather than damage to the mechanism.
- the fan 352 and tooth 351 lifting arrangement provides for a smooth action when the knob is rotated.
- cam 321 When the knob is released and returned to the initial position, cam 321 returns the lock plate through engagement with a suitable recess (not shown), and cam 323 lowers the main plate assembly 350.
- rollers 364, 365 maintain pressure on the fingers, and are forced into the upper part of recess 375 by the resilient outward force of the fingers 363. At the end of the fingers 363 travel, this force is removed and rollers 364, 365 can drop into the lower part of the recess. Extra fingers 371 on the front slide plate 369 and rear slide plate 368 ensure this occurs prior to the downward travel.
- any time a correct card is engaged the combination card can be changed.
- the present invention lends itself readily to master keying, and many possible keys may match any given combination card - particularly maid keys, and master keys (of various levels) may be employed.
- master keys of various levels
- the lock In a master keyed environment, for instance a hotel, it is desirable that only authorised personnel can alter the combination key.
- the lock has two open positions, only one of which allows the combination card 244 to be removed.
- the H-shaped opening on front slide plate 369 allows, in combination with pin in shutter 380, for such an arrangement.
- Normal user keys leave the pin at the top, and then bottom, of the left arm of the H.
- the master key leaves the pin in the middle, so that the shutter 380 can be slid back (see Figures 12, 13) and the combination card changed.
- the lock shown in Figures 12 and 13, also allows for a privacy feature.
- the user card may be inserted into a slot once in the room. This engages a bevelled end of pin 381, which protrudes so as to indicate a desire for privacy. It also engages a small lug (not shown) which prevents other cards, or the maid's card, from being fully inserted.
- the master card may include a notch corresponding to the lug, so as to override the privacy request if necessary.
- the user cards and combination cards may be formed from any suitable material, but a plastics material such as is commonly used for credit cards is preferred.
- Cards may be cut by any suitable means, but a computer-controlled punching system is currently preferred.
- the present invention is suitable for use particularly in commercial or industrial situations, such as hotels, offices, factories, schools and the like. It is also, however, applicable for domestic use. Whilst the embodiments described relate to door latch applications, the invention can equally be used for locks of any type, subject to modifications of size, shape. etc.
