ABSTRACT:
A cabinet latch has a generally cylindrical body that is mountable on a closure panel or the like. A passage is formed through the body along a center axis, and opens through forward and rearward end regions of the body. An assembly of operating components is protectively nested within the body passage, including an operating element that is journaled for rotation within the forward end region of the body passage, and an elongate shank that has a portion which projects from the rearward end of the body passage and carries a pawl. The shank and the pawl are rotatable about and movable axially along the center axis to position the pawl among unlatched, latched and latched-clamped positions for selectively releasing, retaining, and securely clamping the closure in a closed position relative to an associated cabinet or the like. Movement of the pawl is effected in response to rotation of the operating element, and is controlled by the assembly of operating components that is carried within the body passage. A half turn rotation of the operating element in one direction of rotation causes the pawl to move in sequence (1) by rotating a quarter turn about the center axis from an unlatched position to a latched position, and (2) by translating axially along the center axis from the latched position to a latched-clamped position. A half turn rotation of the operating element in the opposite direction reverses the pawl's movements. A snap ring installed in the rearward end region of the body passage retains the operating components in place in the body passage, and is readily removable to permit component removal for lubrication and service.
