Abstract: The invention is an improved device for securing doors against break-in, even when the door is unlocked. The invention consists of a hasp-like retainer member, an eye-type retainer member, and a bar-like security piece of rectangular cross-section. The retainer members are affixed to a wall or door casing on each side of the doorway of the door to be secured at approximately the mid-height of the door. The hasp-like retainer, which is hinge-like in operation, may be folded back against the wall or the door casing when not in use. When in use the hasp-like end is opened to a position generally perpendicular to the face of the wall of the casing. The bar-like security piece, being of a cross-sectional area that is slightly less than the opening in the hasp-like end of the retainer, and of a configuration that will fit into the hasp-like slot, is inserted into the hasp-like retainer member with the opposite end secured to the eye-type retainer member.

Abstract: Improvement in an inside-installation system for barring intruders from access through an opening such as a patio door opening, said system of the type having a series of swinging, slidable rods suspended from an over-head track and held in spaced array by a bar held in brackets at the ends with pin securance at one end and padlock securance at the other; the improvement comprising: two or more bars engaged by a headed pin with a hole for padlocking near the head so that a bar can be captured between head and hole and locked, providing a fast, secure lock for the whole system, with quick release, and providing manufacturing simplicity and improved security.

Abstract: A guard system for preventing unauthorized entry through sliding patio doors and the like even when the glass is broken, while preserving unobstructed appearance when not in use, includes a set of vertical rods hung from a track secured across the inside top of the patio door to be protected, and extending past it to one side so all rods can be slid out of sight behind a customary patio door curtain, and apparatus holding the rods in spaced parallel relation to bar the patio door to intruders, this apparatus including a horizontal bar across the inside of the patio door midway up and securable at each end by quick attach-detach brackets; the horizontal bar has holes through it for holding the rods in position; a sill track runs across the patio door sill on the inside and prevents the bottom of the rods from being pushed inward; the rods can be pivoted and lifted for insertion into the horizontal bar; alternative modes of deployment are disclosed.
