Definitions

  • the present application relates to locking apparatus, particularly, but not exclusively, locking apparatus for use on a mechanical combination door lock.
  • Such locks are typically provided with a series of alphanumeric buttons (often 4, 6, 8, 10 or 12 buttons) and a knob or handle which can be grasped by the user.
  • an authorised user dials the correct passcode into the mechanism, then turns the knob or handle in order to unlock the mechanism.
  • the passcode on such locks can typically be changed to suit a user's preference by dismantling a portion of the lock (normally from the rear) and switching the orientation of certain locking pins provided in the body of the lock; however, for security reasons this normally requires that the lock is first opened to gain access to the rear / inside of the door before then removing the lock from its mount on the door.
  • US20150000355A1 is directed to a mechanical combination lock which includes a base having a cavity, a central shaft provided inside the cavity, and a plurality of combination control units provided on the central shaft, wherein each combination control unit includes a combination disc having at least three combination regions that correspond respectively to different combination conditions.
  • US20150000355A1 provides the mechanical combination lock whereby one button can set a combination with 2 or more bits.
  • a locking apparatus which includes:
  • the locking apparatus may include a pair of parallel locking tumblers, and the plurality of teeth may project inwardly from each of the two longitudinal side plates of the first control plate.
  • the locking apparatus may further include an angled slide provided underneath the code change button, the angled slide being formed with a slanted surface which engages with an inner edge of a second control plate.
  • the second control plate may include a series of tabs engaging respectively with the series of coding disc clutch plates on the central axle of each locking tumbler; whereby when the code change button is pressed after the selected group of the buttons have been pressed, the angled slide urges the second control plate to make a translational movement relative to the base, resulting in that the series of coding disc clutch plates dislocate from the series of button engagement disc clutch plates by the series of tabs, thereby allowing a user to change the access code by selecting and pressing another group of the buttons, and changing angular orientation of the button engagement disc clutch plates relative to their corresponding coding disc clutch plates.
  • each button engagement disc clutch plate may include three recessed portions formed along a peripheral portion thereof, and each coding disc clutch plate may include two projected portions formed along a peripheral portion thereof; wherein when the two projected portions are engaged with two of the three recessed portions, the cut-out aperture of the coding disc clutch plate is aligned with the teeth of the first control plate, and when the two projected portions are engaged with another two of the three recessed portions, the cut-out aperture of the coding disc clutch plate is out of alignment with the teeth of the first control plate.
  • a primary spring and a secondary spring are provided around the button pin of each button to resiliently return the button to its original position after having been pressed and released by the user.
  • a tertiary spring is provided between adjacent sets of engaging button engagement disc clutch plate and coding disc clutch plate on each central axle for biasing each coding disc clutch plate against its engaging button engagement disc clutch plate.
  • a pair of quaternary springs is provided on the first control plate for biasing the first control plate towards the actuating hub.
  • the base is provided with a locking block including a block body with an enlarged head, the block body being inserted into a bore formed at the base, such that an inner end of the block body abuts against an inner end of the angled slide of the code change button, and an outer end of the block body is provided with the enlarged head located on an outer surface of the base; wherein the locking block is held in place within the bore when the base of the locking apparatus is held against and secured on a panel, and the locking block drops out of the bore after the locking apparatus is detached from the panel, and the inner end of the angled slide is inserted into the bore through an opening by pressing the code change button.
  • the locking apparatus may further include a reset button; a reset slide provided underneath the reset button; a coding bar mounted on the base between the first and second locking tumblers and formed with a sloped surface facing the reset slide; and a quinary spring mounted between one end of the coding bar and the base for biasing the coding bar in one direction; wherein when the selected group of the buttons are pressed, their respective coding disc clutch plates rotate and engage with the coding bar, and when the reset button is pressed, the reset slide presses on the sloped surface and urges the coding bar to move in an opposite direction against biasing force of the quinary spring, thereby releasing the coding disc clutch plates to their initial positions, and when the reset button is released, the coding bar returns to its initial position.
  • each button pin protrudes perpendicularly from the button pin of the button, and the pair of button pin engagement levers projects in a direction radially outwardly from the central axle.
  • the selected group of the buttons may include one or more of the buttons provided on the cover plate.
  • the locking apparatus 10 of the present application may include a strong and durable cover plate 12, a plurality of key press buttons 14, and an opening / closing knob or grip handle 16.
  • the key press buttons 14 may be provided with a number of letters / numerals (not shown) such that, once a user has keyed in the correct code, the user is then able to rotate the grip handle 16 in order to unlock the lock and gain access to the otherwise secured area.
  • At least one of the key press buttons may be designated as a code change button 19. In the present embodiment, this is shown as the bottom button in the first column of buttons; however, this could be provided on any one (or many) of the buttons 14.
  • Fig. 1a shows another embodiment of the grip handle 16' of the locking apparatus 10.
  • the locking apparatus 10 may be provided with a base 15 upon which may be mounted an inner actuating hub 17, first and second parallel code operated locking tumblers 18, 20, a first control plate 26, a second control plate 22 and a series of button pins 28 which connect at their upper end to the buttons 14 and at their lower / intermediate ends to the locking tumblers 18, 20 as will be described subsequently.
  • the base 15 allows the locking apparatus 10 to be securely attached to the surface of a door or other such arrangement and provides a secure base upon which the other components of the apparatus are mounted.
  • the inner actuating hub 17 may be directly connected to the outer grip handle 16. Referring to FIG. 3 , a circumference of the actuating hub 17 may be formed with a recessed portion 17a which defines two projections 17b abutting against two sides of a raised portion 26a formed at one end of the first control plate 26 respectively such that when the actuating hub 17 rotates clockwise or anticlockwise, one of the two projections 17b presses against a corresponding one of the two sides of the raised portion 26a of the first control plate 26 (and move it if the apparatus is unlocked yet be prevented from such movement if the apparatus is locked as described subsequently).
  • An angled slide 32 may be provided beneath the code change button 19.
  • the angled slide 32 may be formed with a slanted surface 33, as shown in Fig. 2 , which can engage with an inner edge 24 of the second control plate 22 in a sliding fashion, whereby downward movement of the angled slide 32 results in a corresponding translational movement of the second control plate 22 in the direction indicated by arrow X in Fig. 2 .
  • the first control plate 26 can be a longitudinal structure having two longitudinal side plates 27.
  • a series of teeth 42 may extend inwardly from each of the two longitudinal side plates 27.
  • the first control plate 26, the two side plates 27 and the teeth 42 may be integrally formed as one piece.
  • the first control plate 26 and the second control plate 22 may move independently in a longitudinal direction.
  • the locking tumblers 18, 20 each comprise a central axle 34 mounted to the base 15 and upon which are mounted a series of coding disc clutch plates 36 and a series of corresponding button engagement disc clutch plates 38.
  • each coding disc clutch plate 36 comprises at least one cut-out aperture 37
  • each button engagement disc clutch plate 38 comprises a pair of button pin engagement levers 40 which may project in a direction radially outwardly from the central axle 34.
  • a protruded portion 29 ( Figs. 6a-6b ) may protrude perpendicularly from the button pin 28 and can be positioned between the pair of button pin engagement levers 40.
  • the locking apparatus of the present application may have only one locking tumbler, and the plurality of teeth may be formed only on one longitudinal side plate of the control plate.
  • each coding disc clutch plate 36 The relative angular position of each coding disc clutch plate 36 relative to each button engagement disc clutch plate 38 is what determines whether the teeth 42 of the first control plate 26 are able to translate along the length of the apparatus or not since, in certain angular positions (such as that shown at the left side of Fig. 5 ), the coding disc clutch plate 36 will block such movement of the teeth 42; whereas, in other positions (such as that shown at the right side of Fig. 5 ), the aperture 37 in the coding disc clutch plate 36 will align with the teeth 42 in order to allow such translating movement.
  • primary springs S 1 and secondary springs S2 may be provided around the button pins 28 in order to resiliently return the buttons 14 to their original position after having been pressed and released by a user.
  • the grip handle 16 In use, prior to a user entering the correct access code, if the user attempts to rotate the grip handle 16 (and hence the underlying actuating hub 17) one of the two projections 17b (depending upon which direction the user turns the grip handle 16) will press against a corresponding one of the two sides of the raised portion 26a of the first control plate 26.
  • the first control plate 26 cannot move due to at least one of its teeth 42 being prevented from translating along the length of the apparatus by at least one of the coding disc clutch plates 36 as previously described. This therefore prevents the handle 16 from being rotated and hence prevents the lock from being opened.
  • the code change button 19 cannot be depressed prior to entry of the correct access code since downward movement of the button is prevented by the engagement between the angled slide 32 and the inner edge 24 of the second control plate 22 (which itself cannot move until the correct access code has been entered.
  • buttons might be included in the correct access code, e.g. the code might be "1234".
  • each button pin 28 rotates the aperture 37 of each of the four coded clutch plates 36 such that the apertures 37 align with the teeth 42.
  • the user With the correct access code entered, the user is able to depress the code change button 19. Doing so forces the angled slide 32 down against the inner edge 24 of the second control plate 22. This co-operation between the angled slide 32 and the inner edge 24 in turn translates each of the coding disc clutch plates 36 from the position shown in Fig. 3 to the position shown in Fig. 4 such that the coding disc clutch plates 36 are effectively dislocated from the button engagement disc clutch plates 38 by means of a series of corresponding tabs 48, as illustrated in Figs. 3a-3d , formed on the second control plate 22 and engaging with the series of coding disc clutch plates 36 respectively. The user then selects a new code by pressing whichever buttons 14 they desire (e.g. 5678) in order to change the angular orientation of certain button engagement disc clutch plates 38 relative to their corresponding coding disc clutch plates 36.
  • buttons 14 they desire e.g. 5678
  • Figs. 6a-6d and Figs. 7a-7d show the difference in angular orientation present in the coding disc clutch plates 36 and the button engagement disc clutch plates 38.
  • each button engagement disc clutch plate 38 may include three recessed portions 35 formed along a peripheral portion thereof, and each coding disc clutch plate 36 may include two projected portions 39 formed along a peripheral portion thereof.
  • the cut-out aperture 37 of the coding disc clutch plate 36 is aligned with the teeth 42 of the first control plate 26.
  • the cut-out aperture 37 of the coding disc clutch plate 36 is out of alignment with the teeth 42 of the first control plate 26.
  • the second control plate 22 may be formed with a series of tabs 48 engaging respectively with the series of coding disc clutch plates 36 mounted on the central axle 34 of each locking tumbler 18, 20.
  • the code change button 19 is pressed after the selected group of the buttons 14, which correspond to the access code, have been pressed, the angled slide 32 urges the second control plate 22 to make a translational movement relative to the base 15, resulting in that the series of coding disc clutch plates 36 are dislocated from the series of button engagement disc clutch plates 38 by the series of tabs 48, thereby allowing a user to change the access code by selecting and pressing another group of the buttons 14, and changing angular orientation of the button engagement disc clutch plates 38 relative to their corresponding coding disc clutch plates 36.
  • the locking apparatus of the present application has the advantage of allowing the access code of the locking tumbler to be quickly and easily changed by a user without requiring the locking apparatus to be removed or dismantled.
  • resilient means may be provided within the body of the apparatus in order to resiliently bias components of the apparatus in the open, closed, engaged or disengaged configurations.
  • the resilient means may include coiled springs or any other appropriate means.
  • buttons 36 translate to the left of Fig. 3 or Fig. 4 , the button engagement disc clutch plates 38 do not move since they are held in position by the button pins 28.
  • Each button pin 28 is returned to its original position by the action of primary and secondary springs S1 and S2 ( Fig. 8 ).
  • the tabs 42 are allowed to move freely between the coding disc clutch plates 36 through the cut-out apertures 37.
  • the coding disc clutch plates 36 are allowed to be moved by their corresponding tabs 48, thereby dislocating the coding disc clutch plates 36 from the button engagement disc clutch plates 38, and allowing angular orientation of the coding disc clutch plates 36 (coded or non-coded) to be changed.
