    DETAILED DESCRIPTION

    [0013] Below are more detailed descriptions of various concepts related to and implementations of methods, apparatuses, and systems associated with the embodiments introduced above. The illustrative embodiments described herein are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein and illustrated in the figures, can be arranged, substituted, combined, and designed in a wide variety of different configurations, all of which are explicitly contemplated and made part of this disclosure.

    [0014] As shown in FIGS. 1-3, a lock system 10 includes a multi-component key (e.g., a two-component key), shown as key 100, and a locking mechanism, shown as lock 200. As shown in FIGS. 1-4, the key 100 includes a first handle portion, shown as bow 110, a second, inner keyed portion, shown as keyed shaft 120, extending from the bow 110, and a third, outer keyed portion, shown as keyed blade 130, rotatably disposed along the keyed shaft 120. According to an exemplary embodiment, the bow 110 is configured to permit an operator of the lock system 10 to hold the key 100 and insert the key 100 into the lock 200 and turn the key 100 therein, as described in greater detail herein.

    [0015] As shown in FIGS. 1-4, the keyed shaft 120 has a cylindrical structure that extends perpendicularly from the bow 110. A free end of the keyed shaft 120 opposite the bow 110 includes or defines a first unique interface (e.g., ridges, curved waves, a keyed face, etc.), shown as keyed profile 122. The keyed shaft 120 includes a retainer, shown as tab 124, protruding or extending laterally outward therefrom. In some embodiments, the tab 124 is fixed to the keyed shaft 120. In some embodiments, the tab 124 is detachable from the keyed shaft 120 (e.g., via a screw-thread interface to permit selective removal of the keyed blade 130 therefrom, etc.). In some embodiments, the tab 124 is a spring-biased element that can be selectively depressed into the keyed shaft 120 and biased outward by a spring (e.g., to permit selective removal of the keyed blade 130 therefrom).

    [0016] As shown in FIGS. 1-4, the keyed blade 130 includes a tubular component, shown as sleeve 132, that interfaces with (e.g., slides onto, is disposed around, etc.) and rotates about the keyed shaft 120. The keyed blade 130 includes or defines (a) a second unique interface, shown as keyed profile 134, and (b) a slot, shown as tab guide 136. The keyed profile 134 includes a unique set of teeth. The teeth define a pattern of peaks and valleys (i.e., cuts and bittings). In some embodiments, the keyed profile 134 is integrally formed with the sleeve 132. In such embodiments, the keyed blade 130 may be swapped or interchanged with another sleeve-keyed blade 130 to facilitate reconfiguring the key 100 (see, e.g., FIG. 4). In some embodiments, the keyed profile 134 is detachably coupled to the sleeve 132 such that the keyed profile 134 may be interchangeable with other keyed profiles 134 to facilitate reconfiguring the key 100. As shown in FIGS. 1-4, the tab guide 136 of the sleeve 132 is configured to align with and receive the tab 124 of the keyed shaft 120, longitudinally securing the keyed blade 130 along the keyed shaft 120 while permitting partial rotation (e.g., 90 degree rotation) of the keyed shaft 120 relative to the keyed blade 130 (i.e., when the keyed shaft 120 is rotated, the tab 124 translates within and along the tab guide 136 between the ends thereof).

    [0017] As shown in FIGS. 1-3, the lock 200 includes a main housing, shown as lock housing 202, that encloses a locking assembly (e.g., pins, a swing latch, gears, etc.) including one or more retainers, shown as pins 240, and a locking arm, shown as swing latch 250. The lock housing 202 has a first housing portion, shown as swing latch housing 210, a second housing portion, shown as key housing 220, extending forward from and perpendicular to the swing latch housing 210, and a third housing portion, shown as pin housing 230, disposed along and above the key housing 220. The swing latch housing 210 defines an internal guide, shown as latch channel 212, and an aperture, shown as slot 214, extending through a face of the swing latch housing 210 to the latch channel 212. A first end of the key housing 220 defines an external opening, shown as keyhole 222. An opposing second end of the key housing 220 and the swing latch housing 210 cooperatively define a passage, shown as keyed shaft aperture 224, leading from the key housing 220 into the swing latch housing 210. As shown in FIG. 3, an upper end of the pin housing 230 defines one or more first pin apertures, shown as upper pin apertures 232. As shown in FIG. 1, a lower end of the pin housing 230 and an upper end of the key housing 220 cooperatively define one or more second pin apertures, shown as lower pin apertures 234, leading from the pin housing 230 into the key housing 220.

    [0018] As shown in FIGS. 1-3, each of the pins 240 has a first, upper portion, shown as hook portion 242, and a second, bottom portion, shown as peg portion 244. The hook portions 242 extend through the upper pin apertures 232 and the peg portions 244 extend through the lower pin apertures 234 into the key housing 220. Each of hook portions 242 defines an aperture, shown as latch shaft aperture 246, variously positioned along a length of the hook portion 242 such that the position of the latch shaft aperture 246 varies between at least some of the pins 240.

    [0019] As shown in FIGS. 1-3, the swing latch 250 includes a body, shown as latch arm 252, disposed within the swing latch housing 210. The latch arm 252 has (a) a first, lower end that includes a second unique interface (e.g., ridges, curved waves, a keyed face, etc.), shown as keyed profile 254, extending/protruding therefrom (or, alternatively, defined or recessed therein) and in alignment with the keyed shaft aperture 224 and (b) a second, upper end that includes a bar, shown as swing bar 256, extending through the slot 214 and selectively received within and retained by the hook portions 242 of the pins 240.

    [0020] As shown in FIG. 2, when the key 100 is inserted into the key housing 220 through the keyhole 222, (a) the keyed profile 134 of the keyed blade 130 engages with the peg portions 244 of the pin 240 and (b) the keyed profile 122 of the keyed shaft 120 extends through the keyed shaft aperture 224 and engages with the keyed profile 254 of the swing latch 250. The engagement between the keyed profile 134 of the keyed blade 130 and the peg portions 244 of the pins 240 causes the pins 240 to variably lift or elevate through the upper pin apertures 232 of the pin housing 230 based on the shape of the keyed profile 134 such that the latch shaft apertures 246 of the hook portions 242 of the pins 240 align and, therefore, permit the swing bar 256 to freely rotate through the latch shaft apertures 246 and disengage from the hook portions 242 of the pins 240 to unlock the lock 200. According to an exemplary embodiment, the keyed profile 134 of the key 100, the relative positioning of the pins 240 along the pin housing 230, and the positioning of the latch shaft apertures 246 on each of the pins 240 are unique to the lock system 10. In this way, the keyed profile 134 of the keyed blade 130 must correspond with the positioning of the latch shaft apertures 246 of the hook portions 242 of the pins 240 and the positioning of the pins 240 along the pin housing 230 to unlock or lock the lock 200.

    [0021] As shown in FIGS. 2 and 3, with (a) the keyed profile 134 of the keyed blade 130 in engagement with the peg portions 244 of the pins 240 and (b) the keyed profile 122 of the keyed shaft 120 in engagement with the keyed profile 254 of the swing latch 250, the bow 110 may be turned or rotated by the user such that the keyed shaft 120 rotates within and relative to the keyed blade 130. As shown in FIG. 3, the engagement of the keyed profile 122 of the keyed shaft 120 with the keyed profile 254 of the swing latch 250 causes the latch arm 252 to rotate with the keyed shaft 120 such that the swing bar 256 disengages from the pins 240 and moves within the latch channel 212 to reconfigure the lock 200 from the lock configuration as shown in FIGS. 1 and 2 and the unlocked configuration shown in FIG. 3. Rotating the swing bar 256 away from the pins 240 causes the lock 200 to define an unlocked position. When in the unlocked configuration, the keyed blade 130 remains in an upright orientation, while the bow 110 and the keyed shaft 120 are rotated relative thereto (e.g., ninety degrees). According to an exemplary embodiment, the keyed profile 122 of the key 100 and the keyed profile 254 of the swing latch 250 are unique to the lock system 10. In this way, the keyed profile 122 of the keyed shaft 120 must correspond with the keyed profile 254 of the swing latch 250 to lock or unlock the lock 200. In some embodiments, the keyed profile 122 of the key 100 and the keyed profile 254 of the swing latch 250 are common across two or more of the lock systems 10.

    [0022] As shown in FIGS. 2 and 3, as the bow 110 is turned or rotated by the user, the tab 124 of the keyed shaft 120 translates along the tab guide 136 of the keyed blade 130. In some embodiments, the tab 124 is biased towards a nominal orientation along the tab guide 136 such that the bow 110 and the keyed profile 134 of the keyed blade 130 are biased into vertical alignment. By way of example, movement of the tab 124 within the tab guide 136 may compress a spring (e.g., a torsion spring). Once the user stops applying rotational force to the bow 110, the spring may bias the tab 124 along the tab guide 136 and, therefore, the key 100 back into the nominal position (e.g., the position shown in FIG. 2). While the keyed profile 122 of the keyed shaft 120 is engaged with the keyed profile 254 of the swing latch 250, the return of the key 100 to the nominal position also rotates the swing latch 250 back to the top of the latch channel 212 such that the swing bar 256 re-engages with the pins 240. The user may then remove the key 100, causing the pins 240 to fall downwards to return the lock 200 to the locked configuration. However, should the key 100 be removed while the lock 200 is in the unlocked configuration, as shown in FIG. 3, the swing latch 250 remains in the position shown in FIG. 3, and the lock 200 remains in the unlocked configuration.

    [0023] Referring now to FIG. 4, an exploded view of the key 100 and its component parts are shown, according to an exemplary embodiment. As discussed above, the key 100 includes the bow 110 with the keyed shaft 120. The keyed blade 130 is removably coupled to the keyed shaft 120. In some embodiments, the tab 124 and tab guide 136 facilitate coupling the keyed blade 130 to the keyed shaft 120. In other embodiments, the keyed blade 130 coupled to the keyed shaft 120 by a variety of means other means, such as magnets, a cammed profile, or other similar means that detachably and rotationally couple the keyed blade 130 to the keyed shaft 120. Accordingly, a first keyed blade 130 may be replaced or changed out for a second keyed blade 130 having a different keyed profile 134. In other embodiments, the keyed profile 134 may be detachably coupled to the sleeve 132 (e.g., via magnets, fasteners, a snap-fit engagement, sliding retention fit, etc.) such that a first keyed profile 134 may be replaced or changed out for a second, different keyed profile 134. With the key 100 having a different keyed profile 134, the pins 240 can be repositioned and/or replaced with different pins 240 to correspond with the different keyed profile 134. Accordingly, a user can re-key the lock system 10 by interchanging pins 240 and key profiles 134.

    [0024] As shown in FIG. 5, the lock 200 is installed in a door 500 including a doorknob 510, a deadbolt assembly 520, and a thumb turn 530. In some embodiments, at least a portion of the lock housing 202 of the lock 200 is disposed within the door 500. As shown in FIG. 5, the swing latch 250 includes a deadbolt interface, shown as cam bar 258, that extends or protrudes from the latch arm 252 in an opposing direction of the keyed profile 254. According to an exemplary embodiment, the cam bar 258 is configured to interface with a cam slot 522 in the deadbolt assembly 520. An opposing side of the cam slot 522 of the deadbolt assembly 520 may receive a cam bar 532 extending from the back of the thumb turn 530. In some embodiments, the same cam slot 522 receives the cam bar 258 of the swing latch 250 and the cam bar 532 of the thumb turn 530. Accordingly, the deadbolt assembly 520 may be extended and retracted via the lock 200 and/or the thumb turn 530 to lock and unlock the door 500.

    [0025] As discussed above, when a user inserts the key 100 into the lock 200, the keyed profile 122 of the keyed shaft 120 mates with the keyed profile 254 of the swing latch 250. As the keyed shaft 120 and swing latch 250 rotate, the cam bar 258 of the swing latch 250 rotates therewith. Therefore, the cam bar 258 rotates within the cam slot 522 of the deadbolt assembly 520, driving the deadbolt assembly 520 to lock and unlock the door 500. Also, as the cam bar 258 rotates within the cam slot 522, the cam bar 532 of the thumb turn 530 is rotatably engaged to move the thumb turn 530 between a first position (e.g., corresponding to the locked position) and a second position (e.g., corresponding to an unlocked position). Although the lock system 10 is shown as being implemented as a door lock for the door 500 in FIG. 5, the lock system 10 may be implemented with other lock applications that would be appreciated by one having ordinary skill in the art (e.g., a pad lock, a safe, a keysafe, a mailbox, a lock box, etc.).

    [0026] As shown in FIG. 6, the locking assembly of the lock 200 includes an internal locking mechanism 260. In exemplary embodiments, the internal locking mechanism 260 is disposed within the pin housing 230. The internal locking mechanism 260 includes a first gear and a second gear, shown as bottom gear 264 and top gear 262. Additionally, the internal locking mechanism 260 is shown to include a keyed blade 272 coupled to a spring 268 at an end opposite the gears 262, 264. In exemplary embodiments, the keyed blade 272 is connected via the spring 268 to the lock housing 202. In exemplary embodiments, the bottom gear 264 and the top gear 262 are rotatably coupled to one another by meshing teeth. The bottom gear 264 is coupled to the latch arm 252 on an opposing side of the keyed profile 254 (e.g., a rear side). In some embodiments, the top gear 262 includes a tapered member 266 (e.g., conical, rounded, etc.). In some embodiments, the gears 262, 264 are rotatably coupled to a thumb turn (e.g., the thumb turn 530 shown in FIG. 5). The tapered member 266 is aligned with the keyed blade 272, such that the tapered member 266 engages with the keyed blade 272 upon rotation of the top gear 262. In this example, the pins 240 include a set of pegs 270 on a rear side of the hook portions 242, opposite the latch shaft apertures 246.

    [0027] In an example, the pegs 270 on the rear side of the pins 240 correspond to/are in line with the latch shaft apertures 246. In this way, the keyed blade 272 may move the pins 240 by engaging the pegs 270 to align the latch shaft apertures 246 with the swing bar 256. For example, a user may enter through the door 500 of FIG. 5 and relock the lock 200 using a thumb turn 530 on the inner side of the door 500. In this example, the thumb turn 530 rotates the top gear 262 clockwise. As the top gear 262 rotates, the tapered member 266 engages with the keyed blade 272 to push the keyed blade 272 away from the gears 262, 264, thereby compressing the spring 268. As the keyed blade 272 is pushed away from the gears 262, 264, it engages with the pegs 270 on the rear side of the pins 240 to shift the pins 240 along the peaks of the keyed blade 272, thereby aligning the latch shaft apertures 246 into a substantially straight line. Simultaneously, the teeth of the top gear 262 mesh with the teeth of the bottom gear 264, causing the bottom gear 264 to rotate counterclockwise. The bottom gear 264 rotates the swing latch 250 counterclockwise, towards the pins 240. In this way, the swing bar 256 moves inside the hook portions 242 of the pins 240 through the aligned latch shaft apertures 246. In an example, the latch shaft apertures 246 align when the thumb turn is substantially vertical. As the thumb turn 530 rotates to the locked position, the tapered member 266 moves aside the keyed blade 272, releasing the spring 268 from its compressed position. The spring 268, upon moving from the compressed position to a neutral position, moves the keyed blade 272 back towards the gears 262, 264. This, in turn, causes the keyed blade 272 to disengage the pegs 270, thereby allowing the pins 240 to fall downward around the swing bar 256 to return the lock 200 to the locked configuration.
