BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates generally to door latch handles and more specifically it relates to a door latch opening system for providing efficient and convenient opening of a door latch.




2. Description of the Related Art




Door latches have been in use for years. A door latch is comprised of a latch mechanism attached to the interior of a door near a door jam with a handle pivotally extending from the latch mechanism.

FIGS. 1 and 2

illustrate an exemplary door latch structure. To open the door latch, the user presses upon the handle thereby actuating the latch mechanism into an open position.




The handles utilized upon door latches are often times relatively small in size and length. The size and length of the door latch handles makes them difficult to engage by a user of limited physical abilities or an individual carrying objects such as groceries.




Examples of patented devices which may be related to the present invention include U.S. Pat. No. 369,085 to Barnett; U.S. Pat. No. 5,713,614 to Anderson; U.S. Pat. No. 4,101,153 to Dozier; U.S. Pat. No. 4,223,931 to Neary; U.S. Pat. No. 5,231,731 to Jones, Jr.; U.S. Pat. No. 268,984 to Bergen; U.S. Pat. No. 289,369 to Foshee; U.S. Pat. No. 4,397,489 to Lind; U.S. Pat. No. 3,827,739 to Overholser; U.S. Pat. No. 280,799 to Ohno; U.S. Pat. No. 4,629,228 to Marko et al.; and U.S. Pat. No. 2,058,685 to Haan, Jr.
