Abstract
A storm door lock apparatus is set forth wherein a clamp is secured to an associated screen-door type closure member that further secures a slidable rod mounted with an abutment surface for actuation by a user with a pivoted lever at the other end of said rod for canting about a piston rod associated with a door closure. Additionally, a generally "L" shaped link is securable to the abutment member for allowing engagement and access by a user.
Claims7
A door latching mechanism for use in combination with a door including a fixed cylinder and an axially reciprocating piston rod comprising,
- a latch clamp means for securement to said cylinder including a first cylindrical clamp formed with a discontinuous interior clamping surface for direct contact about said cylinder, and a second cylindrical clamp integral with said first cylindrical and radially spaced parallel to said first clamp, and
- an actuator rod reciprocatably and slidably secured with said second clamp;
- an abutment block secured to a first end of said actuator rod exteriorly of a first axial end of said second clamp, and
- a first end of a detent lever pivotally secured to the second end of said actuator rod exteriorly of the second axial end of said second clamp, and
- said detent lever including a second end pivotally secured to a cant lock, said cant lock including a central opening slidably accepting said piston rod therethrough, said detent lever positioned adjacent an end of said cylinder to tilt said cant lock in abutment with said cylinder to latch said cylinder relative to said piston rod when said actuator rod is slid in a first direction parallel to said cylinder and to tilt and unlatch said cant lock when said actuator rod is reciprocated in a second direction.
