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.

1. A retrofit door latch attachment for a push-button door latch having a hand grip having a convex surface comprising: a lever mounted at a pivot and lying tangentially, and in close proximity to the hand grip of the door latch, the pivot being formed by the interaction of the lever with the convex surface of the grip, the lever having a first end of the lever opposed to the push-button latch actuator, and a second end of the lever extending below the grip, so that pulling on the lever at a point between the pivot and second end pivots the lever about the pivot, engaging the said first end with the push-button latch actuator so as to operate the latch and enable opening of the door. 2. An attachment of claim 1 where the lever is mounted to the convex hand grip by means of a fastener placed through a countersunk hole in the lever which is aligned with a hole in the grip, the fastener and countersunk hole cooperating to act as a pivot. 3. An attachment of claim 2 wherein the fastener is placed through a resilient washer inserted between the lever and grip. 4. An attachment of claim 3 where the said second end extends down to rest substantially adjacent the door. 5. An attachment of claim 4 where the said first end has a slight recess to cup the push-button latch actuator for limiting relative side-to-side movement of the lever and actuator during operation. 6. An attachment of claim 4 where the said first end has a cup attached thereto which fits over the push-button latch actuator for limiting relative side-to-side movement of the lever and actuator during operation. 7. An attachment of claim 6 where the said first end has a flexible boot which fits over the upper end of the push-button door latch, covering the push-button latch actuator, and for excluding adverse weather from the actuator. 8. A retrofit door latch attachment for a push-button door latch having a hand grip comprising: a washer; and a lever mounted at a pivot and lying tangentially, and in close proximity to the hand grip of the door latch, the washer being sandwiched between the lever and the hand grip, the pivot being formed by the interaction of the lever, the washer and the grip, the lever having a first end of the lever opposed to the push-button latch actuator, and a second end of the lever extending below the grip, so that pulling on the lever at a point between the pivot and second end pivots the lever about the pivot, engaging the said first end with the push-button latch actuator so as to operate the latch and enable opening of the door.
