An adjustable corner tool is provided having outwardly biased blades. The back surfaces of the blades are connected to an angle control assembly that includes fixed-length arms pivotally connected between each of the blades and a central mounting block. Springs rotationally bias the arms away from each other such that the arms push against the back surfaces of the blades to urge the blades apart. Resistive force applied against the front surfaces of the blades when is use moves the blades together. Thus, the adjustable corner tool dynamically adjusts to variations in wall corner angles. The adjustable corner tool can be used with corners in the range of about 160 degrees and 40 degrees and the angle of the tool can also be fixed or maximally limited. In addition, the adjustable corner tool may be adapted to also function as an injection head for delivering spreadable material to a corner.
An adjustable corner tool comprising:
An angle control assembly for a corner tool having first and first and second blades, each blade having a mating edge, a front surface and a back surface, the blades hingedly connected at the mating edges, the back surfaces defining an angle, the angle control assembly comprising:
The adjustable corner tool of claim 20 having first and second stop members, the first stop positioned on the mounting block adjacent to an outer edge of the first arm, the second stop positioned on the mounting block adjacent to an outer edge of the second arm.
