Title: Adjustable length cable lock and package locking device, system, and method

Description:
FIELD OF THE INVENTION 
     The invention relates generally to the field of locks and locking systems and methods and, more particularly, to an adjustable length cable lock and package locking device, system, and method. 
     BACKGROUND OF THE INVENTION 
     People and businesses may wish to make increasing use of couriers for delivery of parcels, including to homes unattended by intended parcel recipients. An intended recipient may wish to secure a received parcel, even when not at home, against risk of theft. Otherwise, a thief may steal a parcel left unattended outside the home. Couriers, and companies with a large home delivery component in their business models, may benefit from a device, system, or method that makes it more difficult for would-be thieves to steal parcels left unattended outside the home. 
     Ideally, such a device, system, or method might be usable with a wide variety of parcel sizes, might require a courier to spend only a few moments in securing a parcel, and might require a home user to spend only a few moments in releasing a secured parcel—all while making it more difficult for a would-be thief to otherwise make off with the parcel. And, with increased confidence in parcel delivery, even while users are away, the economy may see increased adoption of courier home delivery, greater profits for associated businesses, and greater customer satisfaction and confidence. 
     In fields far removed from any associated with courier delivery of parcels, it may have been known, for example, to provide retail security devices with spools that unwind cable loops of desired lengths to wrap around merchandise articles, and with locking mechanisms that otherwise prevented the unwinding of those spools. 
     In other fields, it may have been known to provide a lock with a cable secured to, and slidably received within, a housing. The cable may have been slidable between a locked position (whereat an otherwise movable item was secured to a fixed object) and an unlocked position (whereat the item could be removed from the fixed object). A rotatable locking mechanism may have alternately allowed the cable to slide between different locked positions, and/or prevented its movement in the locked position. Variations on such locks also may have been known, including a variety of different devices, e.g., as follows: wherein an end of a cable fixed to a slidable locking device may have been detachable; wherein both ends of a cable may have been able to slide through the lock in a tightening direction when locked; or wherein the lock may have been unlocked by turning a dial to a correct sequence. 
     Further, it may have been known to provide a locking device having two movable clamp jaws and an actuation lever designed to receive a padlock in a locked position. Elsewhere, it may have been known to provide a tightening device with a movable clamping jaw that permitted a shoelace to be tightened only, with a lever that may have been pressed to release the clamping jaws and loosen the shoelace. 
     It additionally may have been known to provide a lock, for an adjustable cable loop, with three locking positions. The cable may have been freely movable (relative to the lock) in the first position, only tightenable in the second position, and of fixed length and not adjustable in the third position. 
     Prior art and/or art in non-analogous fields may have suffered from one or more shortcomings and/or disadvantages which may preferably be readily appreciable by and/or suggested, in view of the teachings and/or disclosures hereof, to those skilled in the art associated with courier delivery of parcels. 
     What may be needed is a device with a cable tightening mechanism and a separate locking mechanism that does not directly affect the function of the cable tightening mechanism. What may be needed is a such device which also enables lengthening of the cable loop, while the cable loop is locked, if an item has not yet been secured by the device. 
     There may be a need for a device, system and/or method which:
         can be used to lock and/or secure parcels delivered by a courier;   adjusts to fit a wide variety of parcel sizes;   permits a parcel to be placed in a cable loop, and/or with a handle on an end of the cable being pulled to tighten the cable about the parcel;   takes a courier only a few moments (e.g., perhaps about 10-15 seconds) to secure a parcel;   permits the cable to move freely through a mechanism to allow the cable to tighten about the parcel, and/or restrains the cable from being loosened or released until the owner unlocks and removes the parcel;   will give a user confidence that a parcel delivered to the user&#39;s home, while the user is away, will be there when the user returns;   permits an owner to remove a first parcel and make it ready for a second parcel in only a few moments (e.g., perhaps about 20-30 seconds);   uses a simple mechanism; and/or   is easy to use.       

     It is an object of the present invention to obviate or mitigate one or more disadvantages and/or shortcomings associated with the prior art, to meet or provide for one or more needs and/or advantages, and/or to achieve one or more objects of the invention—one or more of which may preferably be readily appreciable by and/or suggested to those skilled in the art in view of the teachings and/or disclosures hereof.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     There is shown in accompanying  FIGS. 1-11  a preferred embodiment of an adjustable length cable lock device  20 , in use with a portable item  16  and a fixed object  18 , according to the invention. The adjustable length cable lock  20  preferably includes elongate first and second cables  22 ,  32  adapted to extend in a cable loop about the portable item  16  (as shown in  FIGS. 8-11 ). As shown in  FIGS. 1-2 and 4-5 , the adjustable length cable lock  20  also preferably includes a locking mechanism  40 , a cable tightening device  50 , and an affixing member  60 . 
     As shown in  FIGS. 1-2 and 4-5 , the first cable  22  preferably has a first securing end portion  28  and an opposing secured end portion  24 . The secured end portion  24  is preferably secured to the affixing member  60  by cable fasteners  62  (as shown in  FIGS. 1-2, 4-5 and 7 ). At the other end of the first cable  22 , the first securing end portion  28  is preferably looped or crimped to receive the locking mechanism  40  (as shown in  FIGS. 1-6 ). 
     As shown in  FIGS. 1-2 and 4-5 , the second cable  32  preferably has a handle end portion  34  and a second securing end portion  38 . The second securing end portion  38  is preferably looped or crimped to receive the locking mechanism  40  (as shown in  FIGS. 2-6 ). 
     The locking mechanism  40  preferably is in the form of a padlock which may be unlocked by a key  48  (as best seen in  FIGS. 1 and 2 ). Via the locking mechanism  40 , the first and second securing end portions  28 ,  38  of the first and second cables  22 ,  32 , respectively, may be securely locked to each other (as best seen in  FIGS. 3 and 6 ) to, in a locked configuration, together form a cable loop (as shown in  FIGS. 1-2, 4-5 and 8 ). 
     The handle end portion  34  of the second cable  32  is provided with a handle  36  that may be pulled (as shown in  FIGS. 9-10 ) to tighten the cable loop formed by the securely locked first and second cables  22 ,  32 . 
     As best seen in  FIG. 7 , the cable tightening device  50  preferably defines a release aperture  54 . The cable tightening device  50  preferably has a selectively actuable release mechanism  56 , in the form of a release lever, which is accessible via the release aperture  54 . The cable tightening device  50  preferably defines a cable passage  52  therethrough. Preferably, the second cable  32  slidably extends through the cable passage  52 . Preferably, the cable tightening device  50  securely engages and permits longitudinal movement of the second cable  32  relative to the cable tightening device  50 , but only in a tightening direction unless the release mechanism  56  is selectively actuated. 
     As shown in  FIG. 7A , the cable tightening device  50  may preferably include a release cam portion  97  engaging the release lever  56 . Together, the cam portion  97  and the release lever  56  pivot about a cam pivot  92 . The cam portion  97  extends, through a cam aperture  90 , into the cable passage  52 . There, the cam portion  97  securely engages the second cable  32 , so as to restrict movement other than in the tightening direction, unless the release lever  57  is selectively actuated. When the release lever  57  is selectively actuated, the cam portion  97  disengages the second cable  32  and permits free longitudinal movement of the second cable  32  both in the tightening direction and otherwise. 
     As shown in  FIG. 8 , the affixing member  60  is preferably secured to the fixed object  18  (e.g., a wall) by object fasteners  64 . The affixing member  60  preferably securely engages the cable tightening device  50  and the fixed object  18 . Preferably, in this manner, the cable tightening device  50  (and the rest of the adjustable length cable lock  20 ) is secured to the fixed object  18 . 
     Preferably, in the locked configuration, the aforesaid movement in the tightening direction operatively tightens the cable loop about the portable item  16  (as shown in  FIGS. 9-10 ) towards a secured configuration (as shown in  FIG. 11 ). 
     In the secured configuration shown in  FIG. 11 , the cable loop preferably engages and secures the portable item  16  against the fixed object  18 , such that the portable item  16  blocks the release aperture  54  to prevent access to the release mechanism  56 . 
     Preferably, the locking mechanism  40  is selectively unlockable to permit removal of the first and second securing end portions  28 ,  38  from each other. This selective unlocking of the locking mechanism  40  preferably permits removal of the portable item  16  from the cable loop and ready access to the release mechanism  56 . 
     A lock fastener  46  (e.g., velcro as best seen in  FIG. 6  or a wall-mounted hook in  FIG. 8 ) is preferably provided to selectively fasten the padlock to the fixed object  18  when the adjustable length cable lock  20  is not in use, and unfasten the padlock from the fixed object  18  when the adjustable length cable lock  20  is in use. 
     There is shown in accompanying  FIGS. 12-15  a second preferred embodiment of an adjustable length cable lock device  20 ′ according to the invention. The adjustable length cable lock device  20 ′—much like the embodiment shown in  FIGS. 1 to 11 —preferably includes a locking mechanism  40 , and elongate first and second cables  22 ,  32  adapted to extend in a cable loop about the portable item  16  (as shown in  FIGS. 8-11 ). As shown in  FIGS. 12 to 15 , the adjustable length cable lock  20 ′ also preferably includes an affixing member  60  and a cable tightening device  50 ′. 
     As shown in  FIGS. 12 and 14 , the cable tightening device  50 ′ preferably defines a release aperture  54 , including a finger release aperture  54   a . The cable tightening device  50 ′ preferably has a selectively actuable release mechanism  56 ′, in the form of a release lever, which is accessible via the release aperture  54  and its finger release aperture  54   a . The cable tightening device  50 ′ preferably defines a cable passage  52  therethrough. Preferably, the second cable  32  slidably extends through the cable passage  52 . Preferably, the cable tightening device  50  securely engages and permits longitudinal movement of the second cable  32  relative to the cable tightening device  50 ′, but only in a tightening direction unless the release lever  56 ′ is selectively actuated. 
     In the preferred embodiment shown in  FIGS. 12 to 15 , and as best seen in  FIG. 15 , the cable tightening device  50 ′ includes a cam member  57 , a spring member  80 , and cable engaging members  76   a ,  76   b , preferably, in the form of two opposing clamshell members on opposite sides of the second cable  32 . Each of the clamshell members  76   a ,  76   b  has a respective gripping surface portion  77   a ,  77   b . The spring member  80  engages a spring ledge  78 . As best seen in  FIG. 13 , the spring member  80  extends into a clamshell chamber  74 , and biases the clamshell members  76   a ,  76   b  into secure engagement of their gripping surface portions  77   a ,  77   b  with the second cable  32 . The clamshell members  76   a ,  76   b  extend into a cam chamber  70 . In the aforesaid secure engagement, movement of the second cable  32  is restricted other than in the tightening direction, unless the release lever  56 ′ is selectively actuated. 
     The cam member  57  engages the release lever  56 ′. When the release lever  56 ′ is selectively actuated, by pivoting it (as shown in  FIGS. 14 and 15 ) and the cam member  57  about a cam pivot  72  (shown, for example, in  FIG. 15 ), the cam member  57  pushes the clamshell members  76   a ,  76   b  back into the clamshell chamber  74  and out of the cam chamber  70 . There, the spring member  80  is compressed, such that it no longer extends into the clamshell chamber  74 . In this configuration, and as best seen in  FIG. 15 , the clamshell members  76   a ,  76   b  do not engage the second cable  32  and permit free longitudinal movement of the second cable  32  both in the tightening direction and otherwise. 
     Preferably, via the affixing member  60 , the cable tightening device  50 ′ (and the rest of the adjustable length cable lock  20 ′) may be secured to the fixed object  18 , e.g., a wall. Persons skilled in the art will appreciate from consideration of  FIG. 11  that, when a package  16  is secured within the cable loop against the fixed object  18 , the package  16  blocks the release aperture  54 , including the finger release aperture  54   a , to prevent access to the release mechanism  56 ′. Selective unlocking of the locking mechanism  40  preferably permits removal of the package  16  from the cable loop and ready access to the release mechanism  56 ′ via the finger release aperture  54   a  of the release aperture  54 . 
     In use, a courier delivery-person may arrive at a person&#39;s residence with a parcel  16 . The adjustable length cable lock  20 ,  20 ′ preferably may be mounted on the fixed object  18  (e.g., a wall of the residence) about one foot off the ground. The courier delivery-person then may simply use the lock fastener  46  to remove the cable loop from the fixed object  18 , loop it around the parcel  16 , and easily pull on the handle  36  to tighten the cable loop about the parcel  16 . 
     The adjustable length cable lock  20 ,  20 ′ will then be secure, and the delivery-person can move on to the next delivery, assured that the parcel  16  will be there waiting when the resident arrives home. 
     When the resident arrives home, the resident may then use the key  48  to unlock the padlock  40 , remove the parcel  16 , loosen the cable loop via the release lever  56 ,  56 ′, and fasten the cable loop back onto the wall  18  using the lock fastener  46 . The adjustable length cable lock  20 ,  20 ′ will then be ready to securely receive another parcel  16  the next time a courier delivery-person comes calling.
