Locking systems and devices and methods for using the systems and devices are provided. A locking system may include a receptacle having a lock and an electronic credential. If the electronic credential is brought into proximity of the receptacle, then a key can be used to open the lock. The electronic credential can be incorporated into a vehicle or into a handheld device.

Locking system

A self-contained combination latch and cam lock adapter module affixes to the rear of any lock (keyed or non-keyed) that has a requisite mating feature. The module is alignable in any of four positions (up, down, left, and right) on the back of the lock for latching in any installed position. The module allows a user to slam closed an associated door or drawer without having to rotate the lock into a locked position. The module retrofits in the field by removing and replacing an existing fixed cam. In one embodiment, a mating part is rotationally spring-loaded so that when the key or knob is turned and then released, the module automatically returns to its locked position, ready to be shut.

Combination slam latch and cam lock adapter

Disclosed are apparatus and methodology for fine tuning the fit and function of a cam lock used to secure an enclosure or similar. A cam lock is provided with a cam and a set of variously sized adjustment pads that may be individually secured at one end of the cam. The adjustment pads each differ in thickness, and are installable on the cam without the need of tools. The variously sized adjustment pads allow field installation and adjustment of the position of cam contact surfaces to easily and quickly adjust positioning for spacing variations due to manufacturing tolerances. Such customized installation provides improved security, reduced noise and rattle of the enclosure door, and a more professional aspect to the installation.

Adjustable cam for cam lock

Apparatus and associated methodology are provided for key operated pin tumbler locks, some of which may incorporate a removable core pin tumbler lock. A selected tumbler of a type commonly used in pin tumbler locks is configured along with a driver pin to control operation of a retainer that, when rotated by use of a control key inserted in the lock, allows alternate selective removal and replacement of the core assembly in the lock. Also, or separate therefrom, one or more tumbler holes may be formed or drilled in a manner so as to prevent engagement of a tumbler with the bite of a key. Presently disclosed structures and associated methodology help to reduce any susceptibility to unauthorized techniques practiced against the lock, such as unintentional activation of the tumblers by unauthorized persons through use of a key with so-called 'bumping' techniques.

Key operated pin tumbler locks and methodology

Disclosed are apparatus and methodology for securing access to an underground device such as a storage tank. A lockable blocking plate is secured to a filler cap for an underground storage tank in a manner to inhibit access to the filler cap. The locking mechanism is configured such that the lock and blocking plate may freely rotate with respect to the filler cap. The blocking plate may include a side skirt extending to cover portions of the filler cap and, optionally, portions of a standpipe and coupling for the filler cap. Free rotation is enabled by way of an annular groove in a portion of the locking mechanism, and into which groove one or more locking portions may be inserted, or by way of a freely moving swivel boss attached to the filler cap.

Underground tank lock

An anti-tip linkage mechanism for vertical file cabinets of the type having drawers and/or pivotal front panels includes molded polymeric cam follower housings that snap-fit onto each of the slide channels for the drawers or panels and non-circular connecting rods attached to cam actuators that enable interaction of the anti-tip mechanisms incorporated with each slide channel. Lock actuated auxiliary cam mechanisms and panel locking assemblies controllable by a single cabinet lock are connected with a cabinet lock by linkage bars or cables.

Anti-tip interlocking linkage mechanism for vertical cabinets

Disclosed are apparatus and methodology for providing a resettable manual entry combination and key operated cam lock. Methodologies are provided for enabling changing of the manual entry resettable combination given knowledge of the previous combination and possession of an operable key. In alternative embodiments, provisions are made to prohibit forced opening of the lock by way of the use of foreign objects.

Combination cam lock with improved combination change mode

Disclosed is a lock assembly such as for use with enclosures and access panels. The lock assembly includes a keyhole shaped aperture in a slide portion of the locking assembly that cooperates with double-D shaped protrusions associated with a locking plug. In a locked position, the double-D shaped protrusions inhibit movement of the slide portion. In an unlocked position, the double-D shaped elements may enter a more narrow portion of the keyhole shaped aperture and permit movement of the slide. The slide is associated with additional features so that movement of the slide selectively inhibits or provides consequential movement of other elements that in turn respectively deny or create access to an enclosure.

Panel lock for electronic, electrical or control cabinets

A pin tumbler mechanical lock includes an electronic component incorporated in the key which connects to an axial lead aligned to mechanically engage the spring biased contact of the key whereby in order to operate the lock both the mechanical pin tumblers and the electronic signal provided by the key are necessary.
