  • Patent number: 6502873
    Abstract: A retrofit door latch attachment comprises a lever mounted pivotally to the convex surface of the hand grip of a push-button door latch. The lever has a first upper end aligned with push button actuator and a second lower end for ready access by children and the disabled. The lever does not impede normal use of the push button actuator. Preferably, a countersunk fastener is placed through aligned holes formed through both the lever and grip. More preferably, a recess or cup is formed in the first end of the lever for limiting relative side-to-side movement of the lever and actuator. A flexible boot, preferably added to the lever's upper end, envelopes the top of the actuator and excludes moisture-bearing weather and avoids freeze up in cold climates.
