Abstract
Abstract An apparatus for maintaining ready availability of a lifter tool adapted to lift flat floor panels to expose a fire therebeneath, the apparatus consisting of a flat mounting plate adapted for securement to a wall or other vertically extending surface, a clip bracket centrally secured on said plate, and a lifter tool having a pair of spaced lifter elements occupying substantially the same plane, and interconnected by a bridging handle member. The tool is engaged by the bracket in a position to face the lifter elements toward the plate. The invention further includes the described apparatus in combination with a room including a vertical wall upon which said apparatus is mounted by securement of the mounting plate thereto, a fire extinguisher exposed on said wall adjacent said apparatus, and a floor in the room comprising a plurality of flat panels supported above a sub-floor to define therewith a space containing electrical cables connected to a computer disposed in the room.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
170 words
Apparatus for gaining access to conflagrations comprising: a mounting plate having a monoplanar surface and adapted for securement to a vertically extending surface with the mounting plate positioned on the vertically extending surface with the monoplanar surface of the mounting plate extending substantially parallel to the vertically extending surface; a bracket secured to the monoplanar surface of the mounting plate and projecting outwardly therefrom in a direction substantially normal to the monoplanar surface of the mounting plate, said bracket including a pair of arms defining a throat therebetween; a panel lifting tool including: a handle having a portion extending substantially parallel to said monoplanar surface; panel engaging means carried by said handle adjacent one end thereof and having: a panel engaging portion; and a base portion disposed at the junction of the panel engaging means with said handle, and positioned in said throat with said arms on opposite sides thereof, said tool being supported on said bracket with said panel engaging portion positioned between said mounting plate and said handle.
Claim 2
Dependent Claim
170 words
Apparatus for gaining access to conflagrations comprising: a mounting plate having a monoplanar surface and adapted for securement to a vertically extending surface with the mounting plate positioned on the vertically extending surface with the monoplanar surface of the mounting plate extending substantially parallel to the vertically extending surface; a bracket secured to the monoplanar surface of the mounting plate and projecting outwardly therefrom in a direction substantially normal to the monoplanar surface of the mounting plate, said bracket including a pair of arms defining a throat therebetween; a panel lifting tool including: a handle having a portion extending substantially parallel to said monoplanar surface; panel engaging means carried by said handle adjacent one end thereof and having: a panel engaging portion; and a base portion disposed at the junction of the panel engaging means with said handle, and positioned in said throat with said arms on opposite sides thereof, said tool being supported on said bracket with said panel engaging portion positioned between said mounting plate and said handle.
Claim 3
Dependent Claim
