Definitions

  • the present invention relates to locking apparatus, particularly, but not exclusively to locking apparatus for use on a mechanical combination door lock thereby restricting entry to a secure area.
  • combination locks are often limited by the number of permutations available for a given number of buttons since they typically allow the integers of the predetermined code to be entered randomly in order to gain access, rather than requiring them to be entered in sequence. For example, if the entry code is 1 , 2, 3, 4, a person entering the code 4, 2, 3 1 would be able to gain access.
  • Another disadvantage of known combination locks is that they typically require the keypad to be removed from the door followed by the removal of some internal components before the code can be changed.

  • the three main assemblies making up the locking apparatus include a code entry mechanism 20, an engagement assembly 30 and a housing 40.
  • the code entry mechanism 20 is mounted on a rotatable shaft 22 and comprises an end nut 24, clutch mechanism 26 and a release clutch 28.
  • a lock release arm 32 is also provided.
  • the rotatable shaft 22 has a threaded portion at one end to accept the end nut 24 which ensures that the components remain in position along the rotatable shaft 22.
  • the other end of the rotatable shaft 22 has another end nut where the cylindrical nut is formed into a rectangular protrusion 34.
  • the rotatable shaft 22 has a number of longitudinal grooves provided along its length. In the embodiment shown there are four grooves provided; each circumferentially spaced around the rotatable shaft 22 at 90 degree intervals.
  • Each clutch mechanism 26 comprises a drive member in the form of a lever plate 27 and a driven member in the form of a latch plate 29.
  • the inner surface of the drive member (lever plate 27) is freely rotatable around the outer surface of the driven member (latch plate 29).
  • the lever plate 27 comprises a disc having a button connection arm 38 protruding from one edge of the disc, an obstruction member 42 protruding from the other edge of the disc and a drive transfer slot 44 through a portion of the disc surface. Another drive transfer slot 44 may be provided on the opposite side of the disc.
  • the driven latch plate 27 has a cylindrical section 46 of uniform diameter, and an enlarged diameter section which may be provided by a washer 50.
  • the washer is fixed around the uniform diameter section 46 by gear teeth 52 on its inner circumference.
  • the washer 50 separates the latch and lever plates by a small distance longitudinally along the rotatable shaft 22.
  • a drive transfer pin 54 projects from the face of the washer 50 in order to correspond with the drive transfer slot 44 of the lever plate 27.
  • the button connection arm 38 of the lever plate 27 has a hole which accepts an end of a coiled spring (not shown). This assists with resetting the apparatus after actuation.
  • Each clutch mechanism 26 and associated component mounted on the rotatable shaft 22 are held in position along the shaft by the nut 24.
  • the nut will be expanded, to avoid self-unscrewing during the lifetime of the locking apparatus.
  • the locking apparatus is also provided with a release clutch 28 at the lower end of the rotatable shaft 22.
  • the release clutch 28 is similar in construction to each clutch mechanism 26 although it does not provide the same clutch action since no drive transfer pin or slot are provided between the drive and driven member.
  • the release clutch 28 is also provided with a slot 58 in its outer circumference. The slot is positioned at a location on the release clutch 28 outer edge which allows it to be aligned with a corresponding protrusion 59 of the lock release arm 32 when the correct code has been entered into the code entry mechanism 20. In all other configurations the outer edge of the release clutch 28 obstructs movement of the protrusion 59 and, hence the lock release arm, 32 past the release clutch 28.
  • the lock release arm 32 is attached to a side plate of the lock housing 40 in such a way that it may slide parallel with the rotatable shaft 22 longitudinal axis.
  • a spring (not shown) is provided between the lock release arm 32 and the side plate of the housing 40.
  • the lock release arm 32 has a main spar 60 extending parallel with and spaced apart from the rotatable shaft 22. Projecting from the spar 60 are teeth 62 which coincide with the clutch mechanisms 26 of the code entry mechanism 20.
  • the arm 32 has a bridging member 64 in the form of a rectangular extension at its lower end. The bridging member 64 interacts with the unlocking assembly 30 in order to control whether opening of the lock is possible, as will be described subsequently.
  • the opening assembly comprises a lock re-arm cam 66, rest cam 68 and engagement pin 70.
  • the rest cam 68 is a hollow cylindrical member which is provided with a flatted portion 72 having side wings 74 which project outwardly from the flattened portion 72 in a gradual radius which curves in the opposite direction to that of the cylindrical member.
  • the flattened portion 72 and wings 74 provide a support for the nose of the rectangular protrusion 34 of Fig. 1.
  • the rest cam 68 is in communication with the lock re-arm cam 66 by way of the engagement pin 70.
  • the engagement pin 70 is situated between both the rest cam 66 and the re-arm cam 68 and selectively engages with a seating area 76 provided on the inner circumference of the rest cam 68 cylindrical member.
  • the rest cam 68 is linked to the housing 40 of the apparatus in order to allow actuation by a handle 5.
  • the engagement pin 70 is held in tension by a coiled spring provided in its interior.
  • the housing 40 has a U-shaped bracket member comprising a back plate 80, with two parallel side plates 82 projecting from either side thereof.
  • a rectangular facing plate 84 is provided on the front of the U-shaped bracket member and is slightly oversized in order to overlap the edges of the U-shaped bracket member.
  • a cap plate 86 is provided at the top of the U-shaped bracket.
  • the left hand side of the facing plate 84 is provided with a series of six slots though which code entry buttons 88 project. Holes 90 are provided adjacent each button which allow a coiled spring to connect each button connection arm 38 to the facing plate. A central window 92 is provided in the facing plate to allow easy access to the locking mechanism.
  • the left hand side plate 82 has rectangular slots 94 which coincide with the button attachment arms 38 of the lever plate 27.
  • Each button 88 is formed of a rectangular rod having a slot at the bottom to allow straightforward attachment to the button attachment arm 38 of the lever plate 27.
  • the slots 94 in the side plate 82 help to hold the lever plates 27 of the code entry mechanism 20 in position along the shaft 22.
  • the rotatable shaft 22 and its associated components, lock release arm 32 and unlocking assembly 30 are connected to one another within the housing 40.
  • the code entry mechanism 20 and lock release arm 32 are mounted within the main chamber of the housing 40 and the unlocking assembly 30 is mounted in the holes 81 of the facing plate 84 and the back plate 80.
  • the bridging member 64 sits within the hollow cylindrical portion of the rest cam 68 and is in contact with the engagement pin 70.
  • each obstruction member 42 on each lever plate 27 is arranged such that when the apparatus is in a locking configuration, each obstruction member 42 will reside in between the gap between each of the corresponding teeth 62 of the lock release arm 32. This, in combination with the action of the release clutch 28, prevents the lock release arm 32 from sliding down the length of the rotatable shaft 22 and hence maintains the apparatus in the locked configuration.
  • the shaft 22 rotates by the same amount as the latch plate 29.
  • This rotation of the shaft 22 causes the orientation of each of the other clutch mechanisms 26 along the shaft 22 to be altered.
  • the skilled reader will therefore realise that such rotation of the shaft 22 results in the code requiring to be entered in the correct sequence.
  • Subsequent pressing of the code entry buttons 88 in the correct sequence therefore moves each of the obstruction members 42 out of the gaps between the teeth 62 and out of an obstructing position.
  • the release clutch 28 is rotated by each stepwise rotation of the shaft 22 until the slot 58 in its outer circumference is aligned with the corresponding protrusion 59 in the lock release arm 32.
  • a further advantage of the present invention is that it offers an arrangement which allows the entry code to be changed relatively easily.
  • a hinged facia may be provided over the housing 40. In normal use this facia will remain in a closed position in which the internal mechanism of the housing 40 are covered.
  • the facia can be secured in this closed position by a number of screws, for example, which are accessible only from the secure side of the structure on which the locking apparatus is mounted (e.g. the inside of a secure door).
  • an operator simply unfastens the screws from the inside of the door, flips up the facia and then changes the orientation of each clutch mechanism 26 relative to the shaft 22 as desired.
  • the facia may then be flipped back into position over the housing 40 and the screws re-fastened from the inside of the door.
  • the three main assemblies forming the locking apparatus include a code entry mechanism 120, engagement means 100 and a housing frame 140.
  • the code entry mechanism 120 is mounted on a rotatable shaft 122 and comprises an end nut 124, a series of clutch mechanisms 126 and a release clutch 128 at the end of the shaft opposite the nut 124.
  • a lock release arm 132 (Fig. 26) having a pair of prongs 106 and a window portion 108 is also provided.
  • the rotatable shaft 122 has a threaded portion at one end to accept the end nut 124, which ensures that the components remain in position along the rotatable shaft 122.
  • the other end of the rotatable shaft 122 is formed into a "cone" shape C.
  • the cone shape has a hole 119 for receiving a guide pin (not shown).
  • This end of the rotatable shaft 122 is attached to the housing of the locking apparatus by a bracket 121 which has a tapered guide surface 123.
  • Connecting rods 139 associate each button 188 with a corresponding button connection arm 138 of each clutch mechanism 126.
  • Each clutch mechanism 126 comprises a drive member in the form of a lever plate 127, a driven member in the form of a releasing plate 110 and a shaft gear 111 for mounting the clutch mechanism to the rotatable shaft 122.
  • the lever plate 127 comprises a disc shaped member having a button connection arm 138 protruding from one edge, a button holding protrusion 102 protruding from the diametrically opposed edge and a drive transfer slot 144 through a portion of the disc surface.
  • a drive transfer recess 104 is also provided on the edge of the plate 127 opposite the drive transfer slot 144.
  • the button holding portions 102 of the lever plates 127 mate with leafed springs 103 fixed to the housing frame 140. The action of these springs 103 deactivates a button once it has been pressed. Therefore, if a button is pressed out of sequence the shaft 122 will not advance toward the opening angular position but the lever plate 127 will have been locked in an inactive position.
  • the releasing plate 110 comprises a disc shaped member having a collar 117 on its outer circumference.
  • the collar 117 has an alignment slot 115 therein and a drive transfer pin 154 projecting from a front face of the collar 117.
  • the drive transfer pin 154 corresponds with the drive transfer recess 104 of the lever plate 127.
  • Another drive transfer pin 155 is also provided on the opposed side of the lever plate 127.
  • the shaft gear 111 has an outer diameter corresponding to the inner diameter of the lever plate 127 and the release plate 110.
  • the mating outer surface of the shaft gear 111 and inner surface of the lever plate 127 are relatively smooth to allow the lever plate 127 to freely rotate around the shaft gear 111 without causing the shaft gear 111 to turn, whereas the mating outer surface of the shaft gear 111 and inner surface of the releasing plate 110 engage with one another such that the shaft gear will rotate when the release plate 110 rotates.
  • the inner surface of the shaft gear 111 is provided with a flattened engagement wall 113 which mates with a corresponding flattened portion (not shown) on the rotatable shaft 122 such that rotation of the shaft gear 111 causes rotation of the rotatable shaft 122 and vice versa.
  • a washer (not shown) is provided between the lever plate 127 and the releasing plate 110 to avoid binding.
  • a release clutch 128 is also provided at the top of the rotatable shaft 122 to provide a reference point which determines the rotational position of the shaft 122 that will unlock the locking apparatus.
  • the release clutch 128 is similar in construction to each clutch mechanism 126 although it does not have a lever plate thereon.
  • a slot is positioned at a location on the release clutch 128 outer edge which allows it to be aligned with a corresponding protrusion on the prongs 106 of the lock release arm 132 when the correct code has been entered into the code entry mechanism 120. In all other rotational configurations the release clutch 128 obstructs movement of the lock release arm 132 there past and hence maintains the locking apparatus in the locked configuration.
  • the lock release arm 132 is attached to a side plate of the lock housing 140 in such a way that it may slide parallel with the rotatable shaft 122 longitudinal axis.
  • a spring (not shown) is provided between the lock release arm 132 and the side plate of the housing 140.
  • the prongs 106 of the lock release arm 132 extend beneath the rotatable shaft 122 and extend under the fixing bracket 121.
  • the arm 132 then bends upwardly to form an engagement window 108.
  • the engagement window 108 interacts with the engagement means 100 in order to selectively open the lock, as will be described subsequently.
  • engagement means 100 comprises a barrel having a handle holder 112, a release arm reset member 114, a column reset member 116 and a pin engagement member 118.
  • a spring loaded engagement pin 120 which connects to a spindle 125 of the bolt opening mechanism is also provided.
  • Handle holder 112 connects to the actuation lever 5 of the lock to allow the user to rotate the barrel and hence the bolt opening mechanism after entering the correct entry code, in sequence.
  • the release arm reset member 114 has a cammed outer surface which, when rotated with the handle holder 112, causes a correspondingly shaped head of plate 114A to move down the length of the apparatus thereby disengaging the button holding portions 102 from the leaf springs 103 and returning the lever plates 127 to their initial position.
  • the column reset member 116 has a cammed outer surface which, when rotated with the handle holder 112, pushes against the cone C of the rotatable shaft 122 thereby moving it downward along the longitudinal axis of the apparatus. This downward movement causes the guide pin (not shown) in the hole 119 to abut against the tapered guide surface 123 of bracket 121 thereby causing the rotatable shaft 122 to rotate back to its initial rotational configuration.
  • pin engagement member 118 has an inner cam profile 118A provided with an engagement notch 118B capable of receiving the spring loaded engagement pin 120 of spindle 125.
  • the lock release arm 132 has not been activated (i.e. when the apparatus is locked) the edge of window 108 holds the engagement pin 120 out of the notch 118B and, when the release arm is released, it allows the engagement pin 120 to spring into the engagement notch 118B such that rotation of the barrel via the actuation handle 5 results in rotation of the bolt opening mechanism spindle 125 and hence opening of the lock.
  • the code entry mechanism 120, lock release arm 132 and engagement means 100 are connected to one another within the housing 140.
  • the code entry mechanism 120 and lock release arm 132 are mounted longitudinally within the main chamber of the housing 140 and the engagement means 100 is mounted vertically in line with the window 108 of the lock release means 132, as seen in Fig. 10.
  • the cammed surfaces on the column reset member 114 pushes against the top of the cone C on the rotatable shaft 122 thereby causing it to rotate (due to the previously described interaction between its guide pin and the tapered guide surface 123 of bracket 121) thereby returning the rotatable shaft 122 to its initial angular position.
  • the cammed outer surface of the release arm reset member 114 will also rotate, thereby disengaging the button holding portions 102 from the leaf springs which causes the lever plates 127 to return to their initial starting position.
  • the apparatus does not allow unlocking when the code is entered in any sequence other than the correct sequence, as will now be described.
  • the shaft 122 When a button is pressed in the correct sequence, the shaft 122 is rotated (roughly 9 or 10 degrees in the embodiment shown) due to the interaction between its associated lever plate 127 and release plate 110 by way of the drive transfer recess 104, drive transfer slot 144 and pins 154, 155.
  • the alignment of subsequent clutch mechanisms 126 associated with other buttons, along the shaft 122 are therefore dependent upon the previous button press(es).
  • the pin 154 of the release plate 110 will not initially abut against the end of the drive transfer recess 104 of the lever plate 127 but instead will be part of the way along the recess 104 or indeed be at the opposite end of the recess 104. The same goes for the other drive transfer pin 155 and the drive transfer slot 144.
  • buttons 88 have a series of six buttons on one side of the facing plate 84, minimal modification would be required in order to allow a far greater number of buttons 88 to be provided on either or both sides of the facing plate 84. This may be desirable in order to increase the number of permutations to the code available or to simply have the buttons on one side of the apparatus rather than the other depending upon the layout of the door or other structure on which the apparatus is installed.

Abstract

L'invention concerne un appareil de verrouillage séquentiel utilisé pour verrouiller, par exemple, une porte pourvue d'une poignée d'actionnement et d'un mécanisme d'ouverture de verrou associé. L'appareil présente un bras de déverrouillage, une broche et un barillet associés au bras de déverrouillage de verrou et à un mécanisme d'entrée de code commandant de manière collective le déverrouillage par un utilisateur. Le mécanisme d'entrée de code comprend un arbre rotatif, un élément d'obstruction situé sur l'arbre rotatif de manière à venir sélectivement en contact avec une partie du bras de déverrouillage et une série de mécanismes d'accouplement situés sur l'arbre rotatif. Chaque mécanisme d'accouplement présente des composants de commande et des composants commandés et une partie d'actionnement pouvant communiquer avec un bouton d'entrée associé, de manière que l'activation sélective su bouton d'entrée génère la rotation du bras rotatif, provoquant l'actionnement du bras de déverrouillage. Ce système permet à l'appareil de verrouillage d'être déverrouillé seulement lorsque le code d'entrée est entré de manière séquentielle.
