Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
105 words
A tool for setting a screw anchor, within a wall, said tool comprising: means for threadably engaging the screw anchor; and means for manually applying separate and distinct torque levels to said threadably engaging means, said torque applying means comprising; a first means for manually applying a breakdown torque to said threadably engaging means; and a second means for manually applying a continuous lower level torque to said threadably engaging means following the breakdown of the screw anchor, the lower level torque being substantially less than the break-down torque and occurring in a continuous manner until the screw anchor has been set against the wall.
Claim 2
Dependent Claim
105 words
A tool for setting a screw anchor, within a wall, said tool comprising: means for threadably engaging the screw anchor; and means for manually applying separate and distinct torque levels to said threadably engaging means, said torque applying means comprising; a first means for manually applying a breakdown torque to said threadably engaging means; and a second means for manually applying a continuous lower level torque to said threadably engaging means following the breakdown of the screw anchor, the lower level torque being substantially less than the break-down torque and occurring in a continuous manner until the screw anchor has been set against the wall.
Claim 3
Dependent Claim
31 words
The tool of claim 1 further comprising: means for drivably engaging the slot of a screw inserted into the screw anchor following the setting of the screw by said second means.
Claim 4
Dependent Claim
69 words
The tool of claim 1 wherein said second means for manually applying a lower level torque comprises: a lever having a portion extending outwardly from said threadably engaging means, said lever having a hole spaced from said threadably engaging means, for receiving an index finger which applies an appropriate force to the interior of said hole so as to rotate the threadably engaging means as the finger is rotated.
Claim 5
Dependent Claim
60 words
The tool of claim 3 wherein said lever has a second portion extending in the opposite direction from said lever portion having the hole for receiving the index finger, said second portion terminating in an end having means for engaging the slot of a screw inserted into the screw anchor following the setting of the screw by said second means.
Claim 6
Dependent Claim
93 words
A tool for setting a screw anchor within a wall, said tool comprising: a threadable stem for threadably engaging the screw anchor; and a plastic handle having a middle portion permanently affixed to an end of said threadable stem, said plastic handle furthermore having end portions extending to either side of said middle portion, the first end portion having a hole for receiving an index finger, said hole being spaced from said threadable stem so as to allow for rotation of the stem when the finger is inserted into said hole and rotated.
Claim 7
Dependent Claim
93 words
A tool for setting a screw anchor within a wall, said tool comprising: a threadable stem for threadably engaging the screw anchor; and a plastic handle having a middle portion permanently affixed to an end of said threadable stem, said plastic handle furthermore having end portions extending to either side of said middle portion, the first end portion having a hole for receiving an index finger, said hole being spaced from said threadable stem so as to allow for rotation of the stem when the finger is inserted into said hole and rotated.
Claim 8
Dependent Claim
41 words
The tool of claim 5 wherein said middle portion is inwardly contoured relative to the end portions so as to facilitate a grasping of the handle during initial rotation of the threadable stem so as to break down the screw anchor.
Claim 9
Dependent Claim
35 words
The tool of claim 5 wherein said threadable stem is a bolt having a head completely encapsulated within said plastic handle, said plastic handle having a neck portion extending downwardly from the encapsulated bolt head.
Claim 10
Dependent Claim
40 words
The tool of claim 5 wherein the interior wall of the hole in said first end portion is smoothly molded so as to allow for slippage between the smooth wall and an inserted index finger as the finger is rotated.
Claim 11
Dependent Claim
53 words
The tool of claim 8 wherein said plastic handle has a second end portion extending from said middle portion in a direction opposite to said first end portion, said second end portion having a screwdriver blade for engaging a slot in a screw that has been inserted into a previously set screw anchor.
Claim 12
Dependent Claim
36 words
The tool of claim 9 wherein said second end portion was a recess which surrounds said screwdriver blade so as to guard against slippage during final tightening of the screw within the previously set screw anchor.
Claim 13
Dependent Claim
22 words
The tool of claim 5 wherein said hole extends through the plastic handle in a direction substantially parallel to said threadable stem.
