Abstract
The locking folding T-handle door has a handle, a locking cam with a cutout portion, a latch cam, and a handle shaft rotatably fixing the handle, the locking cam and the latch cam together. A lock, a pan with an aperture formed therethrough for the handle shaft and an aperture for the lock are provided. A slide bar activation cam is fitted to the lock and is adapted to be turned by the lock. A slide bar located between the locking cam and the slide bar activation cam is provided. The slide bar is slidably retained by a slide retainer fixed to an underside of the pan. The slide bar is adapted to be moved into the cutout portion of the locking cam by locking the lock, which thereby prevents the handle from being turned to move the latch cam.
