DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS Reference is now made to Figs. 1 and 2, which illustrate a cylinder lock constructed and operative in accordance with a preferred embodiment of the present invention and comprising a 0 o°°housing 10 in which is defined a plug 12. As illustrated in Fig.
0 0 .oool 1, the plug 12 is formed with circumferential grooves to present ‘a non-linear shear line therebetween.
0eoo The housing 10 and the plug 12 are formed with 0 00 0o* o respective complementary housing chambers 14 and plug chambers 16, plug chambers 16 communicating with a keyway 18 in which is shown disposed a key 20. Housing chambers 14 communicate with the eo o 0 0 outer peripheral surface of housing 10 and are preferably closed by a removable sealing strip 22. The housing 10 preferably comprises an escutcheon 26 and a hardened pin 28. Pin 28 serves to prevent drilling damage to the cylinder.
Gao t° Disposed in each of plug chambers 16 is a multi-element plug pin assembly 30 comprising a core pin element 32 and a peripheral pin element 34 having an aperture 36 through which slidably extends core pin element 32. Additionally, respective internal and external mastering disks 38 and 24 may be provided as appropriate.
Disposed in each of housing chambers 14 is a multielement housing pin assembly 40 comprising a core pin element 42 and a peripheral pin element 44 having an aperture 46 through which slidably extends an extension 48 of core pin element 42. It is a particular feature of the present invention that
I:
disengagement of core pin element 42 from peripheral pin element 44 is prevented. In the illustrated embodiment, such disengagement is prevented by broadening the extreme end 49 of extension 48 so that it cannot pass through aperture 46.
Alternatively, any other suitable means for preventing ,,isengagement of the core pin element 42 from the peripheral pin element 44 and for maintaining them in generally coaxial 0 alignment may be provided.
0.00 In accordance with the present invention, a compression spring 50 is disposed between core pin element 42 and peripheral pin element 44 such that the two elements are urged to a relative 0o 0 0 0 orientation whereby end 49 is drawn towards aperture 46. Another compression spring 52 is provided between the peripheral pin oc element 44 and the sealing strip 22 for urging the entire multielement housing pin assembly towards the shearing line and I, towards chambers 16.
[i It is a particular feature of the present invention that, due to the fact that the housing pin assembly 40 is Sconstructed so as to prevent undesired and inadvertent j20 disengagement and misalignment thereof, assembly, mastering and servicing of the lock of Fig. 1 is greatly simplified and automated assembly of the lock and of the pin assembly may be realized, producing very significant cost savings.
Reference is now made to Figs. 3A, 3B and 3C which illustrate various embodiments of multi-element pin assemblies useful in the present invention. Fig. 3A illustrates an embodiment of the type illustrated in Figs. 1 and 2 wherein the extension 48 is a separate element from core pin 42 and is embedded therein. Alternatively, pin 42 and extension 48 may be unitarily formed as in Figs. 5A, 5B and Fig. 3B illustrates a three part multi-element pin assembly 60 including a core pin element 62, an intermediate o ,peripheral pin element 64 and an outer peripheral pin element 66.
