1. Field of the Invention
The present invention relates generally to miscellaneous hardware and, more specifically, to a one-way drawer stop providing means for preventing small children from opening sliding door and drawers having the present invention installed thereon.
The present invention is comprised of a counterbalanced latch and stop plate. In the preferred embodiment the latch mechanism is installed on the sliding member while the stop plate is installed on the stationary member.
In operation, the sliding member is moved to an open position where it encounters the stop plate whereupon the exposed end of the latch mechanism is depressed moving it from engagement with the stop plate allowing the sliding member to be fully opened. When the sliding member is moved into the closed position, the latch rides up and over the stop mechanism providing the sliding member with a stop mechanism that prevents opening but not closing.
