Abstract
The combination wedge and notch trowel includes a reversible grip handle and an integrated wedge, for applying cement or adhesive to a substrate surface for installation of tiles. The ergonomically contoured reversible handle allows a user to use the notch trowel in a forward or backwards position with the same hand. The blade portion includes a notch pattern of conically shaped trapezoidal notches and large parabolic notches. The integrated wedge allows a user to use the wedge side of the trowel to pry up and remove tiles.
Claims17
A notch trowel for spreading cement or adhesive over a substrate surface for the installation and removal of tiles, the notch trowel comprising:
- a substantially rigid trowel blade portion having a flat bottom surface and a peripheral blade edge with a smooth side and a series of notches being formed in the peripheral blade edge along at least one other side of the blade edge;
- a wedge member mounted to the blade portion, the wedge member having an elongated flattened rectangular wedge main body portion and a beveled wedge portion tapering from the main body portion to a narrowed rear edge portion abutting the smooth side of the peripheral blade edge, whereby the wedge member can be placed under an edge of a tile to be removed, and can be used to pry up the tile without bending or otherwise damaging the blade portion of the trowel;
- and
- an ergonomic reversible grip handle mounted to the blade portion for manually grasping and manipulating the notch trowel, the ergonomic reversible grip handle including a cylindrical main body formed by a grip portion and a handle support member, the handle support member having an S-shaped curved configuration with an upper support portion connected to the grip portion, a middle neck portion having a curvature tapering from the upper support portion to a base support portion connected to the wedge member, wherein the handle support member curves upwardly from the base support portion to the upper support portion, wherein the upper support portion extends parallel to and over said wedge member toward said smooth side abutting said narrowed rear edge portion of said wedge member.
A notch trowel for spreading cement or adhesive over a substrate surface for the installation of tiles on the substrate surface, the notch trowel comprising:
- a substantially rigid trowel blade portion having a flat bottom surface and a peripheral blade edge with a smooth side and a plurality of notches formed in the peripheral blade edge along at least one other side of the blade edge;
- a handle mounted to the blade portion for manually grasping and manipulating the notch trowel;
- and
- wherein said plurality of notches include a plurality of first short trapezoidal notches, a plurality of second large parabolic notches interspersed among said short trapezoidal notches extending into the blade edge to a greater depth than the first short trapezoidal notches, and a plurality of third intermediate size trapezoidal notches interspersed among said plurality of first short trapezoidal notches and said plurality of second large parabolic notches, and wherein said plurality of third intermediate size trapezoidal notches extend into the blade edge to a greater depth than the large parabolic notches.
