Abstract
Abstract A detachable latching device adapted for use with movable panels, and more particularly for use in combination with removable panels and the related fixed frame structure such as employed in sun-roofs for vehicles, wherein the device comprises a toggle-jointed latch having a pair of toggle bars wherein one defines a latch-handle-link member and the other a toggle arm, each being pivotally connected to the other at one end. The opposite end of the handle-link member is pivotally connected to a mounting bracket attached to the panel; and the toggle bar is pivotally connected to a demountable anchor bracket removably secured to the fixed frame structure wherein the anchor bracket includes a pair of oppositely disposed cleat members that are removably lockable to the fixed frame structure.
