Drywall corner bead cutting device

An improved drywall corner bead cutting device comprising:

• a cutting device base;
• at least one cutting blade assembly mounted on said cutting device base including;
• a corner bead support section including a corner bead support structure mounted on said cutting device base and having a corner bead support wall operative to engage the upper wall of a drywall corner bead having a nose and wing sections, said corner bead support wall including a nose support section and opposite wing support sections for engaging and supporting the upper wall of a drywall corner bead having a longitudinal axis;
• a corner bead support structure cutting blade mounted on said corner bead support structure, said corner bead support structure cutting blade generally diagonally aligned relative to said corner bead support wall such that said corner bead cutting structure cutting blade engages a drywall corner bead supported thereon to cut the drywall corner bead at an angle not perpendicular to the longitudinal axis of the drywall corner bead;
• a cutting arm section including a pivotably mounted cutting arm, handle means and a cutting blade mounted on said cutting arm, said cutting blade positioned adjacent to and parallel with said corner bead support structure cutting blade;
• said cutting blade and said corner bead support structure cutting blade cooperatively operative to cut drywall corner bead supported on said corner bead support wall and extending beyond said corner bead support structure cutting blade into a cutting area defined by interaction of said cutting blade and said corner bead support structure cutting blade via pivoting movement of said cutting arm to drive said cutting blade and said corner bead support structure cutting blade into and through a drywall corner bead thereby dividing the drywall corner bead along a diagonal cut;
• and
• a safety device operative to move in conjunction with pivoting of said cutting arm between an open position where said safety device generally does not restrict access to said cutting area upon said cutting arm being pivoted away from said corner bead support wall and an access prevention position at least partially restricting access to said cutting area upon said cutting arm being pivoted to move said cutting blade into the proximity of and then engage said corner bead support structure cutting blade.

An improved drywall corner bead cutting device comprising:

• a cutting device base;
• two cutting blade assembly mounted on said cutting device base, each of said two cutting blade assemblies including;
• a corner bead support section including a corner bead support structure mounted on said cutting device base and having a corner bead support wall operative to engage the upper wall of a drywall corner bead having a nose and wing sections, said corner bead support wall including a nose support section and opposite wing support sections for engaging and supporting the upper wall of a drywall corner bead having a longitudinal axis;
• a corner bead support structure cutting blade mounted on said corner bead support structure, said corner bead support structure cutting blade generally diagonally aligned relative to said corner bead support wall such that said corner bead cutting structure cutting blade engages a drywall corner bead supported thereon to cut the drywall corner bead at an angle not perpendicular to the longitudinal axis of the drywall corner bead;
• a cutting arm section including a pivotably mounted cutting arm, handle means and a cutting blade mounted on said cutting arm, said cutting blade positioned adjacent to and parallel with said corner bead support structure cutting blade;
• said cutting blade and said corner bead support structure cutting blade cooperatively operative to cut drywall corner bead supported on said corner bead support wall and extending beyond said corner bead support structure cutting blade into a cutting area defined by interaction of said cutting blade and said corner bead support structure cutting blade via pivoting movement of said cutting arm to drive said cutting blade and said corner bead support structure cutting blade into and through a drywall corner bead thereby dividing the drywall corner bead along a diagonal cut;
• and
• the two corner bead support structures extending generally perpendicular to one another and each positioned externally adjacent said operatively associated one of the two cutting arms such that opposite orientations of cuts are made by said two cutting blade assemblies.
