Abstract
A kit for assisting in the location of holes to be drilled in a door of a thickness between 1⅜″ to 1¾″ for the installation of a conventional lock set at a backset of either 2⅜″ or 2¾″ with no additional hardware and without damaging the door. A first guide plate defines a first hole saw guide. A second guide plate is attachable to the first guide plate in one of two orientations and defines a second hole saw guide. At least one clamping member is carried by the second guide plate and extends substantially parallel to the first guide plate. Each of the first guide plate and the clamping member define opposing biasing members such that when mounted on a door, the door is centered within the kit.

A door lock set installation kit for assisting a user in preparing a conventional door for the installation of a conventional lockset, the conventional door defining opposing first and second surfaces and a distal edge, said kit for simultaneously locating a first hole at a selected backset with respect to the distal edge to extend between the first and second surfaces for receiving a cylinder or tumbler of the conventional lockset and a second opening to extend between the distal edge and the first hole and centered between the first and second surfaces for receiving a latch or bolt of the conventional lockset, the door lock installation kit comprising:
- a first guide plate defining:
- a main body having a first surface configured to engage the conventional door first surface;
- a first mating portion defined by said first guide plate on said main body first surface;
- at least one first biasing member configured to engage the conventional door first surface;
- and
- a first hole saw guide carried along a top edge of said first guide plate main body, said first hole saw guide being configured to register with the first hole and defining a through opening configured to closely receive a conventional hole saw for cutting the first hole;
- a second guide plate releasably attachable to said first guide plate in one of a first orientation and a second orientation and configured to engage the distal edge of the door, said second guide plate defining:
- oppositely disposed first and second engagement surfaces, and a midline disposed between said first and second engagement surfaces to bisect said second guide plate;
- oppositely disposed first and second sides;
- and
- oppositely disposed first and second ends
- a second mating portion carried by said first side for selectively engaging said first mating portion when said second guide plate is in either of said first orientation or said second orientation, said first engagement surface being disposed to engage the conventional door distal edge when said second guide plate is disposed in said first orientation, wherein said first engagement surface is disposed a first distance from a center of said first hole saw guide to define a first backset distance, and wherein said second engagement surface being disposed to engage the conventional door distal edge when said second guide plate is disposed in said second orientation, said second engagement surface being disposed a second distance from said center of said first hole saw guide to define a second backset distance, wherein said second mating portion is offset from said midline such that said first distance and said second distance are not equal;
- a second hole saw guide defined between said oppositely disposed first and second engagement surfaces, at a center thereof, said second hole saw guide located to properly register the second hole on the conventional door distal edge;
- and
- at least one clamping member carried by said second guide plate in a selected one of a first clamp orientation and a second clamp orientation, said at least one clamping member being oriented in said first clamp orientation and extending in the same direction as and parallel to said first guide plate when said second guide plate is disposed in said first orientation, and said at least one clamping member being oriented in said second clamp orientation and extending in the same direction as and parallel to said first guide plate when said second guide plate is disposed in said second orientation when said second guide plate is disposed in said second orientation.
A door lock set installation kit for assisting a user in preparing a conventional door for the installation of a conventional lockset, the conventional door defining opposing first and second surfaces and a distal edge, said kit for simultaneously locating a first hole at a selected backset with respect to the distal edge to extend between the first and second surfaces for receiving a cylinder or tumbler of the conventional lockset and a second opening to extend between the distal edge and the first hole and centered between the first and second surfaces for receiving a latch or bolt of the conventional lockset, the door lock installation kit comprising:
- a first guide plate defining:
- a main body having a first surface configured to engage the conventional door first surface;
- a linear channel defined by said first guide plate on said main body first surface, said linear channel defining a longitudinal axis oriented in a transverse direction across said first guide plate and perpendicular to a longitudinal axis of said first guide plate, said linear channel defining an open first end and a closed second end, said linear channel further defining a first keyed portion;
- at least one first biasing member configured to engage the conventional door first surface;
- a first hole saw guide carried along a top edge of said first guide plate main body, said first hole saw guide being configured to register with the first hole and defining a through opening configured to closely receive a conventional hole saw for cutting the first hole;
- and
- at least one first biasing member;
- a second guide plate releasably attachable to said first guide plate in one of a first orientation and a second orientation and configured to engage the distal edge of the door, said second guide plate defining:
- oppositely disposed first and second engagement surfaces, and a midline disposed between said first and second engagement surfaces to bisect said second guide plate;
- oppositely disposed first and second sides;
- and
- oppositely disposed first and second ends
- a rail carried by said first side for selectively engaging said linear channel when said second guide plate is in either of said first orientation or said second orientation, said rail configured to be closely and slidably received within said linear channel through said open first end, said rail defining a second keyed portion configured to engage said linear channel to limit relative movement of said rail to linear movement along said longitudinal axis of said linear channel, said first engagement surface being disposed to engage the conventional door distal edge when said second guide plate is disposed in said first orientation, wherein said first engagement surface is disposed a first distance from a center of said first hole saw guide to define a first backset distance, and wherein said second engagement surface being disposed to engage the conventional door distal edge when said second guide plate is disposed in said second orientation, said second engagement surface being disposed a second distance from said center of said first hole saw guide to define a second backset distance, wherein said second mating portion is offset from said midline such that said first distance and said second distance are not equal;
- a second hole saw guide defined between said oppositely disposed first and second engagement surfaces, at a center thereof, said second hole saw guide located to properly register the second hole on the conventional door distal edge;
- and
- at least one clamping member carried by said second guide plate in a selected one of a first clamp orientation and a second clamp orientation, said at least one clamping member being oriented in said first clamp orientation and extending in the same direction as and parallel to said first guide plate when said second guide plate is disposed in said first orientation, and said at least one clamping member being oriented in said second clamp orientation and extending in the same direction as and parallel to said first guide plate when said second guide plate is disposed in said second orientation when said second guide plate is disposed in said second orientation, each of said at least one clamping member further defining a second biasing member, each of said at least one first biasing members being positioned and configured to cooperate with second biasing member of one of said at least one clamping member in order to center the conventional door with respect to said second hole saw guide defined by said second guide plate.
