Abstract: A latching device for sliding doors/windows which has a smooth, modern appearance and which enables a person to free himself. The device is used in combination with a push-bolt or bayonet style door lock mounted on a sliding door/window. Means for latching the bolt of the lock to the frame of the door/window includes a slotted, slideable frame member. The slideable frame member fits unobtrusively against the frame with no protruding parts. The bolt on the lock can be extended into a notch which is formed in the frame of the door/window and which includes a side opening. When the door/window is locked, the slideable frame member blocks this side opening, so that the bolt cannot escape. Alternately, by bringing a cutout in the frame member into alignment with the side opening, the frame member can be positioned so as not to block the side opening, thereby forming an opening through the bolt can move sideways.

Abstract: The combination of lock assisting devices forming the home security protection kit of the present invention was determined as a result of extensive effort to determine the appropriate product mix to help secure an apartment, condominium, or small home, based upon visiting many apartments, condominium developments, and neighborhoods where small homes are located. These visits resulted in taking inventory of the number of hinged doors, sliding glass doors, ground level windows, and other design features that were in need of some type of auxiliary security device. Based upon this research, it was determined that a product mix of four metal window clamps, four window pins for wood sash windows, one patio door clamp for a sliding glass door, four anti-liftout plates of two different thicknesses for sliding glass doors, and two door braces satisfied the requirements of securing a condominium, apartment, or small home. Therefore, the contents of the kit of the present invention will secure a majority of dwellings.
