Abstract
A grout removal tool includes an adapter having a replaceable cutting blade mounted thereon. The adapter is configured to be installed within a common reciprocating saw. The adapter has a proximal attachment end for attachment to the saw, an elongated proximal leg extending from the proximal attachment end, and an elongated distal leg extending from the proximal leg at an angle to terminate in a distal end whereupon the cutting blade is attached. When the proximal attachment end of the adapter is installed within the reciprocating saw, the cutting blade reciprocates in a parallel plane beneath the plane in which the proximal leg reciprocates. When the cutting blade is reciprocated across a grouted work surface, it results in a high rate of grout removal with low dust dispersion.
Claims31
A grout removal tool comprising:
- a. a proximal end adapted for securement within a power reciprocating saw;
- b. a distal end having two or more blades thereon, each blade having opposing faces, wherein the faces of the blades are adjacently situated in at least substantially parallel and fixed relation so the blades together define a cutting edge;
- c. an elongated proximal leg extending from the proximal end, the proximal leg being oriented at least substantially parallel to the cutting edge;
- and
- d. an elongated distal leg extending between the proximal leg and the distal end, the length of the distal leg being oriented at an angle to the length of the proximal leg.
A grout removal tool comprising:
- a. an adapter having a proximal end and a distal end, the proximal end being adapted for securement within a reciprocating saw;
- b. a blade removably affixed to the distal end of the adapter, the blade having a cutting edge defined thereon;
- the cutting edge extending between a forward end and a rear end, with an axis defined between the forward and rear ends constituting a cutting axis,
- and wherein the blade is removably affixed to the distal end of the adapter at two attachment points, the attachment points being situated along a line situated at an angle to the cutting axis;
- and
- c. one or more supplemental blades removably affixed to the distal end of the adapter, with all blades being adjacently arrayed in at least substantially parallel and fixed alignment.
A grout removal tool comprising:
- a. an adapter including:
- (1) a proximal end;
- (2) a proximal leg extending forwardly from the proximal end along an at least substantially linear path;
- (3) a distal leg extending forwardly from the proximal leg, wherein at least a substantial portion of the distal leg descends at an angle from the path of the proximal leg;
- (4) a distal end situated forward of the distal leg and opposite the proximal end, the distal end having opposing sloped sides which converge inwardly towards each other in a descending direction;
- b. a blade removably affixed to one of the sloped sides of the distal end, the blade having a lower cutting edge defined thereon;
- and
- wherein the distal end does not form a part of the cutting edge.
A grout removal tool comprising:
- a. an adapter having a proximal end and a distal end which is at least substantially flat, the proximal end being adapted for securement within a reciprocating saw, and the distal end having opposing sloped sides each converging slopes inwardly toward the other;
- b. a blade removably affixed to one of the opposing sloped sides of the distal end of the adapter, the blade having a cutting edge defined thereon;
- and
- wherein the distal end does not form a part of the cutting edge.
A grout removal tool comprising:
- a. an adapter having a proximal end and a distal end, the proximal end being adapted for securement within a reciprocating saw, and the adapter extending forwardly and downwardly from the proximal end to the distal end, the distal end having opposing sides;
- b. two or more blades, each having a cutting edge defined thereon and being removably affixed to one of the opposing sides of the distal end of the adapter, the cutting edges of the blades being adjacently and fixedly aligned in a parallel row;
- and
- wherein the cutting edges together define a grout removal cutting edge.
