  • Patent number: 4971374
    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.
