Fig. 4 is a simplified illustration of part of the tumbler of the lock cylinder of Figs. 1 -3, showing tumbler pin assemblies having peripheral pins located at different azimuthal orientations relative to the longitudinal axis of the elongate bore of the cylinder, as viewed along arrow IV in Fig. 3;
Fig. 5 is a simplified pictorial illustration of a key useful in the lock cylinder of Figs. 1 - 4;
Fig. 6 is a simplified illustration of part of a tumbler of a lock cylinder similar to the lock cylinder of Figs. 1 - 3 and which shows a specially configured pin construction; and
Fig. 7 is a simplified pictorial illustration of a key useful in a lock cylinder of the type illustrated in Fig. 6.
Reference is now made to Figs. 1 - 4 which illustrate a lock cylinder constructed and operative in accordance with a preferred embodiment of the present invention. The lock cylinder preferably comprises a cylinder body 10 having an elongate bore 12 extending along a longitudinal axis 14.
A tumbler 16 is rotatably disposed within the elongate bore 12 and defines a keyway 18. A plurality of body pin assemblies 20 are disposed in body pin bores 22 located within the cylinder body 10 and communicate with the elongate bore 12 at a shear line 24.
A plurality of tumbler pin assemblies 26 are disposed in tumbler pin bores 28 located within the tumbler 16 and communicate both with the keyway 18 and with the elongate bore 12 at the shear line 24, the plurality of tumbler pin assemblies 26 being arranged such that upon suitable rotation of the tumbler 16 in the elongate bore 12 about axis 14, each of the tumbler pin assemblies 26 is aligned coaxially with a corresponding one of the body pin assemblies 20.
In accordance with a preferred embodiment of the present invention, the tumbler pin assemblies 26 each comprise a principal pin 30 of selectable length and a plurality of peripheral pins 32, each of selectable lengths, arranged to fit in each principal pin 30 in a selectable non-coaxial arrangement therewith, whereby both the lengths of the peripheral and principal pins and the azimuthal position of the peripheral pins relative to the principal pin provide lock combination parameters.
Correspondingly, in accordance with a preferred embodiment of the present invention, the body pin assemblies 20 each comprise a principal pin 40 and a plurality of peripheral pins 42 arranged to fit in each principal pin 40 in a selectable non-coaxial arrangement therewith. Preferably an individual spring 44 is provided for each principal pin 40 and an individual spring 46 is provided for each peripheral pin 42. The body pin assemblies are retained in the body pin bores 22 by means of bore caps 47.
As seen in Figs. 2 and 3 and most clearly in Fig. 4, in accordance with a preferred embodiment of the invention, the peripheral tumbler pins 32 extend outside the periphery of the principal tumbler pin 30 in which they fit. This is true also for the peripheral and principal body pins 42 and 40 respectively.
In accordance with a preferred embodiment of the invention, the positions of the peripheral pins relative to a principal pin are limited to within a predetermined angular azimuth range relative to the longitudinal axis 14, so as not to extend beyond the shear line. This range is indicated by reference numerals 48 and 50 in Fig. 4 and typically extends to + 15 degrees from longitudinal axis 14.
Preferably, the ends of principal tumbler pin 30 and peripheral tumbler pins 32 adjacent the shear line 24 are configured so as not to extend beyond the shear line 24 and are shaped to conform with the curvature of the shear line 24.
A key corresponding to the embodiment of the invention shown in Fig. 4 is illustrated in Fig. 5, it being noted that the key cuts corresponding to the tumbler pin assemblies 52, 54 and 56 shown in Fig. 4 are indicated by corresponding reference numerals 62, 64 and 66 in Fig. 5.
In the illustrated embodiment wherein each tumbler pin assembly includes a principal pin and two peripheral pins, there are three key cuts for each tumbler pin assembly. These key cuts need not be all arranged in a line parallel to the longitudinal axis 70 of the key but may be located within a predetermined angular azimuth range indicated by reference numerals 78 and 80, relative to the longitudinal axis 70, which corresponds to the predetermined azimuth range of the locations of the peripheral pins, which is indicated in Fig. 4 by reference numerals 48 and 50.
According to an alternative embodiment of the invention, which is illustrated in Fig. 6, the peripheral pins may be located at any desired angular azimuth relative to the longitudinal axis, provided that their ends adjacent the shear line are appropriately configured. This alternative embodiment provides more available locations for the peripheral pins and thus more combinations for the lock. It has the disadvantage of increased complexity.
The principal and peripheral pins indicated at reference numeral 84 lie along a line generally perpendicular to longitudinal axis 96 of the key. Alternatively, the principal and peripheral pins, as indicated at reference numeral 98, may lie along a line, which may be at an angle 99 in the range of approximately 50 to 90 degrees from axis 96.
A key corresponding to the embodiment of the invention shown in Fig. 6 is illustrated in Fig. 7, it being noted that the key cuts corresponding to an principal pin 90 and peripheral pins 92 and 94, as illustrat- ed in Fig. 6, substantially extend along a line perpendicular to axis 96, as illustrated at reference numeral 100 in Fig. 7. Key cuts corresponding to the pin arrangement indicated at reference numeral 98 are slanted with respect to axis 96 corresponding to angle 99.
It will be appreciated by persons skilled in the art that the present invention is not limited to what has been particularly shown and described hereinabove. Rather the scope of the present invention is defined only by the claims which follow:
