DETAILED DESCRIPTION OF THE INVENTION

In accordance with the principles of the invention, apparatus and methods for locking and unlocking a lockable container that has an internal locking mechanism are provided. The apparatus may include a main body including a channel for receiving the container. Examples of containers that may be locked or unlocked in accordance with the principles of the invention are shown in U.S. Publication Nos. 2002/0023853 and 2004/0129587, which are hereby incorporated herein in their entireties. The apparatus may include a magnetic field source coupled to the main body emitting a magnetic field for actuating a container lock disposed at least partially inside the container. The container lock may include an elongated member that engages hinged portions of the container to lock the container. The elongated member may include, and be secured in place within the container by, a catch mechanism that may be magnetically actuated, and may prevent the elongated member from being removed from the container. Apparatus of the invention may include a channel blocker that may be positioned by actuating a channel lock to selectively prevent the magnetic field source from actuating the catch mechanism of a container lock. The channel lock may be actuated by a cam configured to position at least a portion of the channel blocker in the channel. The apparatus may include a ramp retractor coupled to the channel blocker wherein the ramp retractor urges the channel blocker down through the channel by action of the magnetic field. The apparatus may also include a base portion configured to mount the apparatus to a fixture, including but not limited to a counter top.

Since the container lock catch mechanism is actuated by a magnetic field, the container may be both locked and unlocked, in some embodiments of the invention, without removing any portion of the locking mechanism (e.g., a locking member) from the container.

When locked, the container may be displayed, for example, in a live retail or rental environment. A consumer may handle the container, but may be denied access to its contents by the container lock. Once the consumer decides to purchase, rent or lease the contents of the container, the consumer may bring the container to a checkout counter. At the checkout counter, an employee or other authorized user may unlock the lockable container using the apparatus of the present invention.

To unlock a container, the employee or other authorized user will translate the container through the channel of the apparatus so that the container lock catch mechanism will be actuated by the magnetic field emitted from, on or near the magnetic field sources of the apparatus. The container lock may unlock the container when the container is further translated while the catch mechanism remains in an actuated state. To lock the container, the action is reversed.

Since the apparatus of the invention has a channel lock that can be configured to selectively prevent translation of the container through the channel, an employee or authorized user can lock the apparatus and leave the checkout counter unattended. Without a means to unlock the apparatus, it is difficult for an individual to use the apparatus to unlock, and thus open the container. The apparatus can also be locked after hours or when the store is closed.

FIG. 1 shows an exploded view of illustrative apparatus 1, which may be used for locking and unlocking a lockable container for securing an item. Apparatus 1 includes main body 2, which includes channel 3 for receiving a lockable container.

At least one magnet 4 may be supported by main body 2 to provide a magnetic field source that emits a magnetic field for actuating a container lock (not shown) disposed at least partially within a container (not shown). Main body 2 may include one or more of magnets 5 and 6, possibly in addition to first magnet 4, supported by main body 2. Magnets 4, 5 and 6 may be of different sizes, thereby making the configuration of magnets and magnetic fields more difficult to simulate or duplicate. (It should be noted that the three-magnet arrangement of FIG. 1 is merely illustrative of the various magnetic arrangements that can be utilized to create the magnetic field. The number, size and position of the magnets can vary. For example, apparatus 1 may include 4 magnets of varying sizes, rendering it extremely difficult for a thief to properly manipulate four varying shaped magnets to unlock a container.)

In some embodiments of the invention, one or more of the magnets may be a permanent magnet. In some embodiments of the invention, one or more of the magnets may be an electromagnet. Apparatus 1 may include channel lock 7 that interacts with cam 8 that can move at least a portion of the channel blocker 9 through slot 10 into channel 3. Channel blocker 9 may prevent unauthorized use of the apparatus. To move channel blocker 9 into the locked position, a key (not shown), which may be any suitable key, including a cylindrical key, matched to channel lock 7 is inserted into channel lock 7 and turned to rotate cam 8, which moves channel blocker 9 upward into the “locked position.” Graded area 12 of cam 8 pushes on ramped section 11 of channel blocker 9 to move channel blocker 9 upward. In the locked position, channel blocker 9 prevents channel 3 from receiving a container and prevents a container lock catch mechanism from being positioned near the magnetic fields of magnets 4, 5 and 6 and thereby being actuated. Channel blocker 9 may be thus render apparatus 1 temporarily inoperable. Channel blocker 9 may be supported at pivot point 25 (shown in FIG. 6) and may have free end 13 that may be moved into and out of the channel.

To unlock apparatus 1, the key is inserted into apparatus lock 7 and turned in a direction that rotates cam 8 in a manner that lowers channel blocker 9 out of channel 3. Lock nut 14 may be used to keep channel lock 7 from slipping.

A “key-lock counter-mount” feature of some embodiments of the present invention may permit apparatus 1 to be securely coupled to, for example, a retail store checkout counter. Apparatus 1 may have base 15, which may be used to mount apparatus to a fixture such as but not limited to a counter. Fasteners such as but not limited to unidirectional screws may be used to anchor main body 2 to base 15 and the fixture. Plug cover 16, 17, and 18 may be used to cover the fasteners.

For security, any of the known EAS or RFID tags (e.g., an AM or RF non-deactivatable security tag) (not shown) may be mounted on base 13 or coupled to main body 2 of apparatus 1. In such an embodiment, an acoustomagnetic (“AM”) or radio frequency (“RF”) detector may be placed within a retail store to detect if an unauthorized user attempts to steal apparatus 1 or, for example, if a stolen apparatus is brought into the store. The non-deactivatable tags may set off alarms, notifying security personnel.

In some embodiments, apparatus 1 may include an “identification, serialization, and web server with database” feature. A bar code (not shown), for example, may be placed on main body 2 of apparatus 1. The bar code may include information identifying, for example, one or more of the product number or serial number, the name or ID number of the store or other authorized user, the date the product was sold leased or the like to the authorized user, or any other suitable information. This allows a stolen apparatus to be traced through a database containing serial numbers, manufacturing information and store ID of the apparatus distributed to retailers, replicators, or the like. The stolen apparatus may then be traced back to the last listed authorized user.

Apparatus 1 may also include ramp retractor 19 coupled to channel blocker 9. Ramp retractor 19 may be present to urge channel blocker 9 down through slot 10 in the base of channel 3 and out of channel 3 by engaging with a magnetic field. Ramp retractor 19 may be a magnet. Ramp retractor 19 may be a metal component. Ramp retractor 19 may be configured to be forced downward and thus urge channel blocker 9 down through slot 10. Ramp retractor 19 may be configured to be repelled by one or more magnets. Ramp retractor 19 may be configured to be attracted by two or more magnets. Ramp retractor 19 may be both repelled and attracted by one or more magnets. Repelling and attracting magnets, which may include one or more of magnets 4, 5, and 6 may be supported by main body 2 and base 15.

FIG. 2 shows a perspective view of main body 2 of apparatus 1 in accordance with the present invention. Illustrative container 20 is shown entering channel 3 of main body 2. Channel lock 7 and cam 8 (not shown) are configured so that channel blocker 9 is positioned outside of the channel.

FIG. 3 shows a front view of apparatus 1. A portion of channel blocker 9 is present in channel 3. Container 20 is displaced from bottom 21 of channel 3, in a position in which magnets 4, 5, and 6 can not actuate the container lock catch mechanism in container 20.

FIG. 4 shows a partial cross-sectional view of apparatus 1. Channel lock 7 is shown coupled to cam 8 and is configured in an unlocked position so that channel blocker 9 is positioned outside of channel 3. Container 20 thus can be positioned against bottom 21 of channel 3 so that magnetically reactive catch mechanism 22 of the container lock is aligned with magnets such as magnet 4. In this position the magnetic field of the magnets can actuate the container lock catch mechanism.

FIG. 5 shows a partial cross-sectional view of apparatus 1. Channel lock 7 is shown coupled to cam 8 and is configured in a locked position so that channel blocker 9 is positioned at least partially inside channel 3. Channel blocker 9 thus prevents magnetically reactive catch mechanism 22 of the container lock of container 20 from being placed sufficiently close to the magnetic field created by the magnets to actuate catch mechanism 22.

FIG. 6 shows container 20 in channel 3, in contact with bottom 21 of channel 3 of main body 2. Apparatus 1 is in an unlocked position, in which channel blocker 9 is outside of channel 3. This allows catch mechanisms 22, 23, and 24 to align with, and be actuated by, magnets 4, 5, and 6, respectively. In connection with some container locks, magnets 4, 5, and 6 may actuate catch mechanisms such as 22, 23, and 24 and may hold catch mechanisms 22, 23, and 24, and all of the container lock, in place during further translation of container 20. This displaces the container lock with respect to container 20. When further translation causes the release of catch mechanisms 22, 23, and 24 from the magnetic fields, the container lock will have been moved from a position in which container 20 is locked to one in which it is unlocked (or vise-versa). Channel blocker 9 may be supported at pivot point 25 and may have free end 13 that may be moved into and out of the channel 3.

It will be understood that the foregoing is only illustrative of the principles of the invention, and that still other modifications can be made by those skilled in the art without departing from the scope and spirit of the invention.
