Abstract
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. In use, resistive force applied against the front surfaces of the blades moves the blades together. Thus, the adjustable corner tool dynamically adjusts to variations in wall corner angles. The adjustable corner toot can be used with corners in the range of about 160 degrees to 40 degrees and the angle of the tool can also optionally 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.

Claims (21)
1. An adjustable corner tool comprising:
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; and an angle control assembly connected between the back surfaces, the angle control assembly outwardly biasing the blades to urge the blades apart to increase the angle and wherein pressure applied against the front surfaces moves the blades together to thereby decrease the angle.
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; and an angle control assembly connected between the back surfaces, the angle control assembly outwardly biasing the blades to urge the blades apart to increase the angle and wherein pressure applied against the front surfaces moves the blades together to thereby decrease the angle.
2. The adjustable corner tool of claim 1 wherein the angle control assembly further comprises a mounting block pivotally connected between the first and second blades.
3. The adjustable corner tool of claim 2 wherein the angle control assembly further comprises at least one pair of first and second arms, the first arm pivotally connected at a distal end to the first blade and pivotally connected at a proximal end to the mounting block, the second arm pivotally connected at a distal end to the second blade and pivotally connected at a proximal end to the mounting block, at least one of the arms rotationally biased to outwardly bias the blade attached thereto, thereby urging the blades apart.
4. The adjustable corner tool of claim 3 wherein both arms are rotationally biased.
5. The adjustable corner tool of claim 3 having a pair of first and second upper arms and a pair of first and second lower arms, the upper and lower pairs of arms spaced apart to sandwich the mounting block therebetween, the first upper arm being rotationally biased and the second lower arm being rotationally biased.
6. The adjustable corner tool of any one of claims 3 to 5 wherein the angle control assembly further comprises releasable clamping means for providing resistance to the rotational movement of the arms.
7. The adjustable corner tool of any one of claims 3 to 6 wherein the angle control assembly further comprises at least one stop member for limiting the outward rotation of one of the arms.
8. The adjustable corner tool of claim 7 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.
9. The adjustable corner tool of any one of claims 3 to 8 wherein the angle control assembly further comprises first and second mounting plates, the first mounting plate attached to the back surface of first blade and the second mounting plate attached to the back surface of second blade, the first arm pivotally attached to the first mounting plate and the second arm pivotally attached to the second mounting plate.
10. The adjustable corner tool of any one of claims 1 to 9 wherein the angle control assembly outwardly biases the blades by a spring.
11. The adjustable corner tool of any one of claims 1 to 10 wherein the first and second angles are in the range of about 40 degrees to degrees.
12. The adjustable corner tool of any one of claims 1 to 11 wherein the mating edges are beveled inwardly, the beveled edge of each blade adjacent to a hinge cylinder projecting from the mating edge of the other blade, wherein the beveled edge and the hinge cylinder form a substantially tight fit.
13. The adjustable corner tool of any one of claims 2 to 12, the mounting block adapted to receive a conduit for spreadable material, the adjustable corner tool further comprising:
tubing connected between the mounting block and the back surface of at least one of the blades, the tubing in communication with an opening in the mounting block and an opening end in at the at least one of the blades, wherein the tubing directs spreadable material delivered from the conduit into the mounting block to the front surface of the at least one blade.
tubing connected between the mounting block and the back surface of at least one of the blades, the tubing in communication with an opening in the mounting block and an opening end in at the at least one of the blades, wherein the tubing directs spreadable material delivered from the conduit into the mounting block to the front surface of the at least one blade.
14. An angle control assembly for a corner tool having 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:
first and second mounting plates; and a mounting block pivotally connected between first and second mounting plates, the angle control assembly outwardly biasing the first and second mounting plates for moving the plates apart, wherein attachment of the first mounting plate to the first blade and attachment of the second mounting plate to the second blade outwardly biases the blades to urge the blades apart to increase the angle and wherein pressure applied against the front surfaces moves the blades together to thereby decrease the angle.
first and second mounting plates; and a mounting block pivotally connected between first and second mounting plates, the angle control assembly outwardly biasing the first and second mounting plates for moving the plates apart, wherein attachment of the first mounting plate to the first blade and attachment of the second mounting plate to the second blade outwardly biases the blades to urge the blades apart to increase the angle and wherein pressure applied against the front surfaces moves the blades together to thereby decrease the angle.
15. The angle control assembly of claim 14 further comprising at least one pair of first and second arms, the first arm pivotally connected at a distal end to the first mounting plate and pivotally connected at a proximal end to the mounting block, the second arm pivotally connected at a distal end to the second mounting plate and pivotally connected at a proximal end to the mounting block, at least one of the arms rotationally biased to outwardly bias the mounting plate attached thereto, thereby moving the mounting plates apart.
16. The angle control assembly of claim 15 wherein both arms are rotationally biased.
17. The angle control assembly of claim 15 having a pair of first and second upper arms and a pair of first and second lower arms, the upper and lower pairs of arms spaced apart to sandwich the mounting block therebetween, the first upper arm being rotationally biased and the second lower arm being rotationally biased.
18. The angle control assembly of any one of claims 15 to 17 further comprising releasable clamping means for providing resistance to the rotational movement of the arms.
