Abstract
Abstract A safety entry latching arrangement characterized as a pivotal and extendible securing member attached to an existing door hinge assembly secured onto one side of the framework of an entry and selectively connecting to a latch member disposed on the framework at the opposite side of the entry. The securing member is preferably defined by two parts arranged in a slidable telescopic relationship, where spring urged structure serves to maintain the securing member in an outwardly or upwardly extending latching or storage position, respectively. In a typical arrangement, an audible signaling system can be combined with the handle for the securing member to afford additional protection for the user, i.e. to forewarn unwanted entry.
