Lock assembly

A lock cylinder for a door including a wall defining an opening, the lock cylinder operable to interact with a latch bolt assembly, the lock cylinder comprising:

• a housing including a cavity;
• a plug assembly including a casing and a plug housed in the casing and rotatable between a locked position and an unlocked position, the plug operable to interact with the latch bolt assembly, and the casing disposed within the cavity;
• a spin ring member at least partially enclosing the housing, the spin ring member including a tab member;
• an adapter including a wall portion and an annular flange disposed about at least a portion of the wall portion, the flange having a notch configured to receive the tab member, a first surface adjacent an end of the adapter, and a second surface opposite the first surface such that the tab member is engaged with the second surface, the flange retained by the tab member to directly attach the adapter to the spin ring member;
• and
• at least one movable member extending outward from the wall portion and configured to engage the wall of the door to couple the adapter to the door, the movable member being movable inward toward the wall portion against a force biasing the movable member outward.

A lock cylinder for a door including a wall defining an opening, the lock cylinder operable to interact with a latch bolt assembly, the lock cylinder comprising:

• a housing including a cavity;
• a plug assembly including a casing and a plug housed in the casing and rotatable between a locked position and an unlocked position, the plug operable to interact with the latch bolt assembly, and the casing disposed within the cavity;
• a spin ring member at least partially enclosing the housing;
• an adapter coupled to the spin ring member and including a wall portion;
• and
• at least one movable member extending radially outward from the wall portion and configured to engage the wall of the door to couple the adapter to the door, the movable member being movable inward toward the wall portion against a force biasing the movable member outward.

A method of assembling a lock cylinder for a door including a wall defining an opening, the lock cylinder operable to interact with a latch bolt assembly, the method comprising:

• providing a housing including a cavity, the housing configured to interact with the latch bolt assembly;
• providing a plug assembly insertable into the cavity and configured to be operably coupled to the latch bolt assembly, the plug assembly including a casing and a plug housed in the casing and rotatable between a locked position and an unlocked position, and the casing disposed within the cavity;
• providing a spin ring member including a hollow portion and a tab member;
• providing an adapter including an aperture defining an axis, the adapter configured to be inserted into the opening in the door, the adapter including a wall portion and an annular flange disposed about at least a portion of the wall portion, the flange having a notch configured to receive the tab member, a first surface adjacent an end of the adapter, and a second surface opposite the first surface;
• providing at least one movable member extending outward from the wall portion and configured to engage the wall of the door to couple the adapter to the door, the movable member being movable inward toward the wall portion against a force biasing the movable member outward;
• inserting the plug assembly into the cavity of the housing;
• inserting the housing into the hollow portion of the spin ring member such that the spin ring member at least partially encloses the housing;
• and
• attaching the adapter to the spin ring member by engaging the tab member with the second surface such that the flange is retained by the tab member to directly attach the adapter to the spin ring member prior to attachment of the latch bolt assembly to the housing and to the plug and prior to insertion of the adapter into the opening in the door.

A method of installing a lock cylinder into a door including a wall defining an opening, the lock cylinder operable to interact with a latch bolt assembly, the method comprising:

• providing a housing including a cavity;
• providing a plug assembly insertable into the cavity and including a casing and a plug housed in the casing and rotatable between a locked position and an unlocked position, the plug operable to interact with the latch bolt assembly, and the casing disposed within the cavity;
• providing a spin ring member including a hollow portion such that the spin ring member at least partially encloses the housing;
• providing an adapter configured to be inserted into the opening in the door, the adapter including a wall portion and at least one movable member extending radially outward from the wall portion, the member being movable inward toward the wall portion against a force biasing the member outward;
• inserting the plug assembly into the cavity of the housing;
• inserting the housing into the spin ring member;
• attaching the adapter to the spin ring member;
• and
• inserting the adapter into the opening in the door so that the movable member engages the wall of the door and at least temporarily holds the adapter in the opening of the door.

A lock cylinder for a door including a wall defining an opening, the lock cylinder operable to interact with a latch bolt assembly, the lock cylinder comprising:

• a housing including a cavity;
• a plug assembly including a casing and a plug housed in the casing and rotatable between a locked position and an unlocked position, the plug operable to interact with the latch bolt assembly, and the casing disposed within the cavity;
• a spin ring member at least partially enclosing the housing;
• an adapter coupled to the spin ring member and including a wall portion;
• at least one movable member extending outward from the wall portion and configured to engage the wall of the door to couple the adapter to the door, the movable member being movable inward toward the wall portion against a force biasing the movable member outward;
• and
• a spacer including a body, the movable member extending radially outward from the body.

A lock cylinder for a door including a wall defining an opening, the lock cylinder operable to interact with a latch bolt assembly, the lock cylinder comprising:

• a housing including a cavity;
• a plug assembly including a casing and a plug housed in the casing and rotatable between a locked position and an unlocked position, the plug operable to interact with the latch bolt assembly, and the casing disposed within the cavity;
• a spin ring member at least partially enclosing the housing and including one of a tab member and a notch;
• an adapter coupled to the spin ring member and including a wall portion, the adapter further including the other of the tab member and the notch, the notch configured to receive the tab member to directly attach the adapter to the spin ring member, the tab member including a first tab configured to align the adapter with the spin ring member, and a second tab larger than the first tab and configured to attach the adapter to the spin ring member, the size of the notch substantially equal to the size of the first tab;
• and
• at least one movable member extending outward from the wall portion and configured to engage the wall of the door to couple the adapter to the door, the movable member being movable inward toward the wall portion against a force biasing the movable member outward.
