Abstract
A mounting plate used to attach a latch set to a door. The mounting plate includes two sets of attachment apertures (one set is used with a long plate and the other set is used with a rose) and a pair of retention apertures. The retention apertures have a keyhole or teardrop shape that accepts the head of a retention boss on a long plate. Rotation of the long plate relative to the mounting plate causes the retention boss head to engage the mounting plate and attaches the long plate to the mounting plate.
Claims25
A mounting plate comprising:
- a plate having a central aperture therein;
- a plurality of sets of attachment apertures in the plate, each set comprising two attachment apertures, the two attachment apertures in each set being diametrically opposed to one another about the central aperture;
- and
- two retention apertures in the plate, the two retention apertures being diametrically opposed to one another about the central aperture.
A latch set comprising:
- two latch operators;
- and
- a mounting plate attached to the latch operators, the mounting plate having a central aperture, two sets of attachment apertures, the two attachment apertures in a set being diametrically opposed to one another about the central aperture;
- and two retention apertures diametrically opposed to one another about the central aperture, the mounting plate being attached to one latch operator using one set of attachment apertures, the mounting plate being attached to the other latch operator using the retention apertures.
A method of installing a latch set on a door comprising the steps of:
- providing a first latch operator, the first latch operator having two female threaded bosses;
- providing a second latch operator, the second latch operator having two retention bosses extending therefrom;
- providing a mounting plate, the mounting plate having:
- a central aperture;
- two attachment apertures diametrically opposed to one another about the central aperture;
- and two retention apertures diametrically opposed to one another about the central aperture;
- positioning the first latch operator on a first side of the door, the two female threaded bosses extending into a bore in the door;
- manually holding the first latch operator on the first side of the door;
- positioning the mounting plate on a second side of the door, the mounting plate central aperture being aligned with the door bore;
- attaching the mounting plate to the first latch operator with a plurality of screws;
- releasing the manual holding of the first latch operator;
- positioning the second latch operator on the second side of the door, and aligning the second latch operator in a position rotated from a normal installed position of the second latch operator;
- aligning the retention bosses with the larger end of the mounting plate retention apertures;
- placing the retention boss heads through the larger end of the mounting plate retention apertures;
- and
- attaching the second latch operator to the mounting plate by rotating the second latch operator to the normal installed position.
