Abstract:

A core having a plurality of cutouts penetrating from the core surface to the keyway, and a plurality of activator inserts and filler inserts, such that the installer can locate one or more activator inserts in any of the cutouts, and one or more filler inserts in any of the remaining cutouts, to thereby define a program or code to be provided in the respective flank or flanks of an authorized key. At least three and preferably at least five slotted cutouts are provided. The inserts are preferably in the form of generally semi-circular plates on at least one side of the core. In various embodiments, the present invention is directed to a programmable cylinder lock system, a programmable core for a cylinder lock, a core kit by which the installer can program the core in the field, and a novel key adapted to be used with the programmable core.

Abstract:

A core having a plurality of pin bores penetrating from the core surface to the keyway, and a plurality of activator pins and filler pins, such that the installer can locate one or more activator pins in any of the pin bores, and one or more filler pins in any of the remaining bores, to thereby define a code to be provided in the respective flank or flanks of an authorized key. Preferably at least three bores are provided on at least one side of the core; especially preferred are five pin bores on either side of the core fitted with a pattern of activator pins and filler pins, whereas a sixth pin bore on each side, closest to the back end of the core, is fitted with a blocking pin. In various embodiments, the present invention is directed to a programmable cylinder lock system, a programmable core for a cylinder lock, a core kit by which the installer can program the core in the field, and a novel key adapted to be used with the programmable core.

Appl. No.:

10/469946

Inventors:

Thomas DiVito - Southington CT, US

International Classification:

E05B047/06

US Classification:

070/278300

Abstract:

A cylinder lock device () for mounting to a security compartment (), wherein the improvement comprises that the cylinder can be configured by the end user to permit opening of the compartment by at least two of the group of functional operations consisting of turnknob, mechanical key, and electronic key. The cylinder comprises a plug (), a shell () surrounding the plug and defining a first shear line () therebetween, and a housing () surrounding the shell and defining a second shear line () therebetween. One configuration fixes the first shear line to prevent relative rotation between the plug and the shell while permitting rotation of the plug and shell together relative to the housing along the second shear line. Another configuration fixes the second shear line to prevent relative rotation between the shell and the housing while permitting rotation of the plug relative to the shell along the first shear line.

US Classification:

070409000, 070493000

Abstract:

A key blank and key for a core having a plurality of pin bores penetrating from the core surface to the keyway, and a plurality of activator pins and filler pins, such that the installer can locate one or more activator pins in any of the pin bores, and one or more filler pins in any of the remaining bores, to thereby define a code to be provided in the respective flank or flanks of an authorized key. The key or key blank has a bonnet for grasping with fingers and a blade extending from the bonnet and having top and bottom edges spaced along a blade height direction and left and right opposed flanks having planar surfaces spaced apart along a blade width direction. Each of the flanks has a recessed longitudinal channel, and each channel has at least one raised node in the plane of a respective planar surface.

Inventors:

Thomas J. DiVito - Southington CT, US

International Classification:

E05B 15/00

US Classification:

70266

Abstract:

This is a cam lock that has a spring loaded latching cam. The cam has a ramp that allows it to be moved by a blocked surface without the normal radial turning of the plug. The cam retracts in a lateral motion to clear and then pass behind the blocking surface. This way a cam lock can be pushed to closed position rather than rotated.

Assignee:

Kaba High Security Locks, Inc. - Southington CT

International Classification:

E05B 4902

US Classification:

70278

Abstract:

A security system requires the bringing together, at the locking mechanism to be operated from a locked to an unlocked state, of a properly bitted mechanical key and the generator of a digitally coded electrical command signal. The electrical command signal is transmitted through the lock to an actuator so that the lock, when enabled by insertion of the mechanical key, may be operated. The key may define a portion of the signal transmission path between the command signal generator and the actuator.
