Abstract

A cylinder lock (10), including a first cylinder housing (12) in which a first rotor (14) is rotatably disposed and is coupled to a cam (22), and a connecting element (26) attached to the first cylinder housing (12), the connecting element (26) including an elongate bar with a plurality of housing attachment holes (28) formed therein, the elongate bar including a hub (32) with a lock mounting hole (34) formed therein, and a profile element (36) snap fit over the hub (32).

Description

CYLINDER LOCK WITH ADJUSTABLE LENGTH CYLINDER LOCK WITH ADJUSTABLE LENGTH FIELD OF THE INVENTION The present invention relates generally to cylinder locks and particularly to a cylinder lock whose length may be extended or BACKGROUND OF THE INVENTION Double cylinder locks are well which may be locked and unlocked from opposite sides of a door or Such a commonly referred to as a Euro profile typically comprises separately axially aligned each of which is connected to a cam located in a gap between the A key may be inserted in either cylinder to throw the cam and actuate thereby a locking bolt or other locking Double cylinder locks may comprise a unitary since there is a large variety of door a locksmith may need to maintain a large inventory of double cylinder locks to fit all the For this reason and some companies have developed double cylinder locks with adjustable For US Patent to Keller describes a a piece used to adjust the length of a double cylinder The double cylinder lock comprises two barrels in axial alignment on either side of the The web is engageable with internal end parts of the barrel The web has a plurality of which may be selectively aligned with mounting holes on the barrel elements and secured with SUMMARY OF THE INVENTION The present invention seeks to provide an improved and novel cylinder lock whose length may be extended or as is described more in detail The cylinder lock of the present which may be single or may be easily manufactured and assembled at significantly reduced cost compared to prior art BRIEF DESCRIPTION OF THE DRAWINGS The present invention will be understood and appreciated more fully from the following detailed taken in conjunction with the drawings in 1 and 2 are simplified exploded and pictorial of a cylinder constructed and operative in accordance with an embodiment of the present and 3 is simplified pictorial illustration of a connecting element for the cylinder lock of 1 and constructed and operative in accordance with an embodiment of the present DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT Reference is now made to 1 and which illustrate a cylinder lock constructed and operative in accordance with an embodiment of the present Although the cylinder lock 10 will be described as a double it is appreciated that the present invention may comprise a single or double cylinder Lock 10 preferably includes a first cylinder housing 12 in which a first pin tumbler 14 is rotatably Lock 10 preferably also includes a second cylinder housing in which a second pin tumbler 18 is rotatably Each pin tumbler 14 or 18 may be rotated by insertion of a suitable key in a key way instead of pin rotors actuable by a may be The term is used throughout the specification and claims to denote pin rotors and any other suitable rotatable Each pin tumbler 14 or 18 may be coupled to a central cam For pin tumblers 14 and 18 may engage clutch collectively designated by reference which in turn engage cam As is known in the clutch elements 24 are designed such that upon insertion of a key in first pin tumbler first pin tumbler 14 may be rotated together with its clutch elements 24 to rotate cam while at the same time the clutch elements 24 of second pin tumbler 18 do not engage cam upon insertion of a key in second pin tumbler second pin tumbler 18 may be rotated together with its clutch elements 24 to rotate cam while at the same time the clutch elements 24 of first pin tumbler 14 do not engage cam First and second cylinder housings 12 and 16 may be attached to one another by means of a connecting element which is also illustrated in Connecting element 26 may comprise an elongate bar with a plurality of housing attachment holes 28 formed The housing attachment holes 28 may be formed on opposite sides of a centerline 30 of connecting element The housing attachment holes 28 may or may not be symmetric about centerline The housing attachment holes 28 may or may not be equally spaced from one The housing attachment holes 28 may be of the same or different The housing attachment holes 28 may be through holes or may be blind and they may or may not be Connecting element 26 may comprise a hub 32 with a lock mounting hole 34 formed Hub 32 may be centrally located on centerline Lock mounting hole 34 may be used to mount cylinder lock 10 in a door or window with suitable fasteners A profile element 36 may be snugly secured over hub such as but not limited by means of a snap For as seen in profile element 36 may comprise one or more lugs 53 which snap fit into one or more recesses 55 formed in connecting element Profile element 36 may be used to give the assembled cylinder lock 10 the standard look of a Euro profile although the invention is not limited to a Euro Ends of connecting element 26 may fit into mortises 38 formed in first and second cylinder housings 12 and The housing attachment holes 28 may be aligned at a selected position with one or more mounting holes 40 formed in each of first and second cylinder housings 12 and Fasteners such as but not limited screws or rivets that pass through holes 40 and may be used to secure connecting element 26 to first and second cylinder housings 12 and Any number of spacer elements preferably shaped with the same or similar contour of first and second cylinder housings 12 and may be positioned between cam 22 and first and second cylinder housings 12 and The number and size of the spacer elements 44 depends on the desired finished length of the assembled cylinder lock Spacer elements 44 may be formed with mortises 46 to accommodate connecting element elements 48 may be fitted in mortises 38 or if element 48 may be formed with a chamfer 56 that abuts a chamfer 58 formed on connecting element 26 best in which may help hold element 48 in Profile element 36 may comprise one or more protrusions 50 best in that fit into mortises 38 or which may help form a snug It will be appreciated by persons skilled in the art that the present invention is not limited by what has been particularly shown and described Rather the scope of the present invention includes both combinations and subcombinations of the features described hereinabove as well as modifications and variations thereof which would occur to a person of skill in the art upon reading the foregoing description and which are not in the prior insufficientOCRQuality
