Abstract
The present disclosure includes a kit and method for operating or operably connecting an American locking cylinder into a European cylinder type mortise lock with the American locking cylinder functioning with the European cylinder mortise lock in place of the European locking cylinder itself. The present disclosure provides a door cylinder conversion kit that converts the European cylinder mortise lock to be operable with an American cylinder.
Claims15
A mortise lock conversion kit, with the mortise lock defining an orifice providing access to a cam-toggle defining a U-shaped engagement space, with the cam-toggle configured to engage a locking mechanism in the mortise lock, the kit comprising:
- a conversion kit housing, the housing defining a through bore, the housing coupled to the mortise lock in the orifice;
- a mortise conversion hub, the hub having a first circular end and a second end defining a rectangular portion, with the hub defining a slot extending through the hub, the conversion hub configured to rotate within the through bore of the kit housing;
- a mortise cam, with the mortise cam defining a cam arm, a rectangular opening configured to receive the rectangular portion of the conversion hub, and a fastener opening on each side of the rectangular opening, the cam arm configured to engage the cam-toggle in the U-shaped engagement space;
- and
- a pair of fasteners configured to secure the mortise cam to the conversion hub when the conversion hub is disposed in the through bore of the conversion kit housing, with the mortise lock conversion kit configured to receive an American cylinder in the slot defined in the hub to operate the mortise lock.
A mortise lock conversion kit, with the mortise lock defining an orifice providing access to a cam-toggle defining a U-shaped engagement space, with the cam-toggle configured to engage a locking mechanism in the mortise lock, the kit comprising:
- a conversion kit housing, the housing defining a through bore, with the through bore offset radially from the center axis of the kit housing, the housing coupled to the mortise lock in the orifice;
- a mortise conversion hub, the hub having a first circular end and a second end defining a rectangular portion, with the hub defining a slot extending through the hub, the conversion hub configured to rotate within the through bore of the kit housing;
- a mortise cam, with the mortise cam defining a cam arm, a rectangular opening configured to receive the rectangular portion of the conversion hub, and a fastener opening on each side of the rectangular opening, the cam arm configured to engage the cam-toggle in the U-shaped engagement space;
- and
- a pair of fasteners configured to secure the mortise cam to the conversion hub when the conversion hub is disposed in the through bore of the conversion kit housing, with the mortise lock conversion kit configured to receive an American cylinder to operate the mortise lock.
A method to convert a mortise lock for operation with an American cylinder, the mortise lock defining an orifice providing access to a cam-toggle which defines a U-shaped engagement space, the cam-toggle configured to engage a locking mechanism in the mortise lock, the method comprising:
- inserting a mortise conversion hub into a through bore defined in a conversion kit housing, the conversion hub having a first circular end and a second end defining a rectangular portion, with the conversion hub further defining a slot extending through the hub;
- coupling a mortise cam to the conversion hub with a fastener in a fastener opening on each side of a rectangular opening defined in the mortise cam, with the mortise cam defining a cam arm, and with the rectangular opening configured to receive the rectangular portion of the conversion hub, and the cam arm configured to engage the cam-toggle in the U-shaped engagement space;
- and
- inserting the mortise conversion hub and mortise cam into the orifice, with the conversion hub configured to rotate within the through bore of the kit housing and with the cam arm engaged to the cam-toggle, and with the slot in the hub configured to receive an American cylinder to operate the mortise lock.
