Abstract
Disclosed is a chalk line marking tool that has a trigger attached to a spring loaded marker. The spring loaded marker has a cord gripper channel that holds a chalk covered cord. When the trigger is actuated, the spring loaded marker marks a surface with a chalk line mark.
Claims11
A chalk line marking tool used with a marking cord to create a chalk line on a surface comprising:
- a main body extending in a longitudinal direction;
- main body surface stabilizers that extend away from said main body and are configured to be flush with said surface;
- a trigger having a trigger front portion, a trigger rear portion, and a trigger actuator positioned between said trigger front portion and said trigger rear portion, wherein said trigger actuator protrudes from said trigger front portion and said trigger rear portion in an axial direction and a transverse direction that are perpendicular to each other and perpendicular to said longitudinal direction of said main body;
- a spring loaded marker connected to said trigger and configured to move with said trigger;
- marker surface stabilizers on said spring loaded marker that are configured to be flush with said surface and align with said main body surface stabilizers on said main body;
- a trigger spring having a front end connected to said spring loaded marker and a back end connected to said end cap.

A method of making a chalk line marking tool comprising:
- securing one end of a trigger spring to a rear spring holder on an end cap, and securing the opposite end of said trigger spring to a front spring holder on a spring loaded marker;
- sliding said spring loaded marker into a main body of said chalk line marking tool;
- sliding a right trigger rail and a left trigger rail located on a trigger into a right trigger channel and a left trigger channel located on said main body so that said trigger slides along said right trigger channel and said left trigger channel of said main body;
- securing said end cap to said main body of said chalk line marking tool so that said trigger spring biases said spring loaded marker towards main body surface stabilizers on said main body;
- securing said trigger to said spring loaded marker so that said spring loaded marker moves with said trigger.
2 more elements
A chalk line marking tool used with a marking cord to create a chalk line on a surface comprising:
- a main body extending along a main body longitudinal axis;
- main body surface stabilizers that extend away from said main body along a transverse axis that is perpendicular to said main body longitudinal axis, and said main body surface stabilizers are configured to be flush with said surface;
- a trigger having a trigger front portion extending along said main body longitudinal axis, a trigger rear portion extending along said main body longitudinal axis, and a trigger actuator positioned between said trigger front portion and said trigger rear portion, wherein said trigger actuator protrudes from said trigger front portion and said trigger rear portion along said transverse axis, and along a lateral axis that extends laterally from said main body longitudinal axis and is perpendicular to said main body longitudinal axis and said transverse axis;
- a spring loaded marker connected to said trigger and configured to move with said trigger comprising:
- a main shaft that extends along said main body longitudinal axis;
- a right flange extending from said main body longitudinal axis along said lateral axis;
- a left flange extending from said main body longitudinal axis along said lateral axis;
- marker surface stabilizers that protrude from said main body longitudinal axis along said transverse axis, and are configured to be flush with said surface and align with said main body surface stabilizers on said main body;
- an end cap connected to said main body;
- a trigger spring having a front end connected to said spring loaded marker and a back end connected to said end cap.
