Easily openable tubular latch
Abstract
A tubular latch includes: a biasing lever pivotally mounted on a housing of the latch having an upper depression portion operatively pulled by a drag slide biased by a cam of a handle driving shaft, and having a lower forcing portion of the biasing lever operatively pulling a latch for opening the door, whereby upon a depression of a handle secured to the handle driving shaft at a small angle to pull the drag slide rearwardly to bias the upper depression portion of the lever about a lever pivot with a small stroke, the lower forcing portion below the upper depression portion will be biased with a greater stroke for fully retracting the latch for easily opening the door, without requiring a great rotating angle for depressing the handle.
