  "abstract": "A new interior window locking system for preventing intruders from gaining illegal entry into a building. The inventive device includes a pair of horizontally disposed guide rails secured above and below a window within a window frame. A pair of square tubing frames are slidably disposed between the guide rails. Each of the frames have a steel grate disposed therein. A spring-loaded latch assembly is disposed on corresponding inner members of the pair of square tubing frames for engagement thereof.",
  "claims": [
    "1. A new interior window locking system for preventing intruders from gaining illegal entry into a building comprising, in combination: a pair of horizontally disposed guide rails secured above and below a window within a window frame, opposite ends of the rails each having a stop mechanism disposed thereon; a pair of square tubing frames slidably disposed between the guide rails, each of the frames having a generally rectangular configuration, each of the frames having a steel grate disposed therein; and a spring-loaded latch assembly disposed on corresponding inner members of the pair of square tubing frames, the latch assembly including a pair of handles secured to the inner members, the latch assembly including a locking mechanism, the locking mechanism including a horizontal bolt extendable between the pair of handles, the horizontal bolt including an outwardly extending segment disposed centrally thereof the horizontal bolt having a plurality of flanges abutting the handles, the horizontal bolt having a vertical bolt extending upwardly therefrom, an upper free end of the vertical bolt being pivotally coupled with the inner member of one of the square tubing frames, an inner end of the upper free end being coupled with a spring, the spring biasing the vertical bolt against the inner member.",
    "2. A interior window locking system for preventing intruders from gaining illegal entry into a building comprising: a pair of horizontally disposed guide rails for securing above and below a window mounted in a window frame, an upper one of the guide rails being securable to a window frame above a window and a lower one of the guide rails being securable to the window frame below the window, each of the guide rails being generally U-shaped and defining a groove therein being positionable in an opposed orientation; a pair of frames slidably disposed between the guide rails, the frames each having upper and lower edges, the upper edge of each frame being slidably received in the groove of the upper guide rail and the lower edge of each frame being slidably received in the groove of the lower guide rail such that the guide rails resist pulling of the frames away from a window about which the guide rails are mounted, each of the frames having a grate disposed therein; and a spring-loaded latch-assembly disposed on corresponding inner members of the pair of frames for engagement thereof, wherein the latch assembly includes a pair of handles secured to the inner members, the latch assembly including a locking mechanism having a horizontal bolt extendable between the pair of handles, the horizontal bolt including an outwardly extending segment disposed centrally thereof, the horizontal bolt having a vertical bolt extending upwardly therefrom, an upper free end of the vertical bolt being pivotally coupled with the inner member of one of the frames, a spring biasing the vertical bolt against the inner member.",
    "3. The interior window locking system as set forth in claim 2 wherein opposite ends of the rails each have a stop mechanism disposed thereon.",
    "4. An interior window locking system for preventing intruders from gaining illegal entry into a building comprising, in combination: a pair of horizontally disposed guide rails secured above and below a window within a window frame; a pair of frames slidably disposed between the guide rails, each of the frames having a steel grate disposed therein; and a spring-loaded latch assembly disposed on corresponding inner members of the pair of frames for engagement thereof; wherein the latch assembly includes a pair of handles secured to the inner members, the latch assembly including a locking mechanism, the locking mechanism including a horizontal bolt extendable between the pair of handles, the horizontal bolt including an outwardly extending segment disposed centrally thereof, the horizontal bolt having a plurality of flanges abutting the handles, the horizontal bolt having a vertical bolt extending upwardly therefrom, an upper free end of the vertical bolt being pivotally coupled with the inner member of one of the frames, an inner end of the upper free end being coupled with a spring, the spring biasing the vertical bolt against the inner member.",
    "5. The interior window locking system as set forth in claim 4 wherein opposite ends of the rails each have a stop mechanism disposed thereon."
