Kit adapted to allow affixing accessories designed to operate with european locking cylinders, to operate an american type mortise lock

A cylinder-lock assembly configured to allow affixing accessories that are designed to be operatively coupled with a European locking cylinder, to operate an American type mortise lock mechanism, the cylinder-lock assembly comprises:

• a) a cylinder-lock-member comprising a cylinder-housing, having an external shape of a European cylinder housing, and a cylindrical lock core having a cylindrical shaft and a key verification mechanism, wherein said cylinder-housing defines a cylindrical through bore configured to receive said cylindrical shaft adapted to rotate there inside said cylinder-housing, wherein a key engagement end of said cylindrical lock core is adapted to receive a fitted key into a first key-receiving-slit formed therein parallel to the rotational axis of said cylindrical shaft, and wherein a lateral slit is formed at the second circular end of said cylindrical shaft;
• b) an adapting-ring, said adapting-ring defining a first cylindrical through bore on a first side, and a second European-profile shaped through bore on the second side, wherein said first cylindrical through bore and said second European-profile shaped through bore are partially through bores, and wherein said second European-profile shaped through bore is configured to receive said cylinder-housing;
• c) a cylindrical American-lock-housing-member having the dimensions of a standard American cylindrical lock housing, said American-lock-housing-member defining a through cylindrical bore, wherein said first cylindrical through bore of said adapting-ring is configured to receive said American-lock-housing-member;
• d) a rotation-conveyor having a first end defining a first rectangular protruding portion, and a second circular end defining a second rectangular protruding portion, wherein said rotation-conveyor is configured to rotate within said through cylindrical bore of said American-lock-housing-member, and wherein said first rectangular protruding portion is configured to be disposed inside said lateral slit to thereby operationally engage said rotation-conveyor with said cylindrical shaft;
• e) an American-lock cam, with a cam arm and a body having a rectangular opening formed therein, said rectangular opening configured to receive said second rectangular protruding portion of said rotation-conveyor, and said American-lock cam having fastener openings on each side of said rectangular opening, said cam arm is configured to operatively actuate the door lock/unlock mechanism of the American type mortise lock;
• and f) at least two fasteners configured to secure said American-lock cam to said second circular end of said rotation-conveyor that is disposed inside said through cylindrical bore of said American-lock-housing-member, wherein said cylinder-lock assembly is configured to operatively convey rotational motion of said fitted key, disposed inside said first key-receiving-slit of said cylindrical shaft, to said American-lock cam, to thereby actuate the door lock/unlock mechanism of the American type mortise lock.
