Abstract
A line lock assembly for locking a retraction assembly of a chalk box may include a line lock cover (250) operably coupled to a housing of the chalk box to form a line lock member enclosure, and a line lock member (260) disposed within the line lock member enclosure. The line lock member may be configured to move responsive to rotation of the line lock cover to alternately lock the retraction assembly and unlock the retraction assembly based on a position of the line lock cover.
Claims17
A chalk box comprising:
- a housing having an aperture;
- a line lock cover operably coupled to the housing;
- a reel assembly enclosed within the housing;
- a string having a first end operably coupled to an end hook and configured to extend from the housing through the aperture and having a second end operably coupled to the reel assembly;
- a chalk reservoir in which the string is retained or through which the string passes prior to extending out of the aperture;
- a retraction assembly configured to interface with the reel assembly to enable the string, after extension from the housing, to be wound on the reel assembly responsive to operation of the retraction assembly;
- and
- a line lock assembly configured to lock the retraction assembly to prevent winding or unwinding of the string,
- wherein the line lock assembly comprises a line lock member disposed in a line lock member enclosure,
- wherein rotation of the line lock cover, relative to the line lock member, rotates the line lock member to, based on a position of the line lock cover, lock the retraction assembly to prevent winding and unwinding of the string or unlock the retraction assembly to permit winding and unwinding of the string.

- a reel assembly enclosed within the housing;
- a string having a first end operably coupled to an end hook and configured to extend from the housing through the aperture and having a second end operably coupled to the reel assembly;
- a chalk reservoir in which the string is retained or through which the string passes prior to extending out of the aperture;
- a retraction assembly configured to interface with the reel assembly to enable the string, after extension from the housing, to be wound on the reel assembly responsive to operation of the retraction assembly;
- and
- a line lock assembly configured to lock the retraction assembly to prevent winding or unwinding of the string,
- wherein the line lock assembly comprises a line lock member disposed in a line lock member enclosure,
- wherein the line lock member enclosure is formed between a retaining plate and a line lock cover,
- wherein the line lock cover is operably coupled to the housing to enable rotation of the line lock cover relative to the housing to move the line lock member to alternately lock the retraction assembly and unlock the retraction assembly based on a position of the line lock cover;
- wherein the line lock cover includes a first pair of extrusions that extend from the line lock cover toward the retaining plate through the line lock member enclosure.

A chalk box comprising:
- a housing having an aperture;
- a reel assembly enclosed within the housing;
- a string having a first end operably coupled to an end hook and configured to extend from the housing through the aperture and having a second end operably coupled to a reel of the reel assembly, the reel being rotatable about an axis to wind or unwind the string;
- a chalk reservoir in which the string is retained or through which the string passes prior to extending out of the aperture;
- a retraction assembly configured to interface with the reel assembly to enable the string, after extension from the housing, to be wound on the reel assembly responsive to operation of the retraction assembly;
- and
- a line lock assembly configured to lock the retraction assembly to prevent winding or unwinding of the string,
- wherein the line lock assembly comprises a line lock member disposed in a line lock member enclosure,
- wherein the line lock member enclosure is formed proximate to a line lock cover,
- wherein the line lock cover is configured to interface with the line lock member to alternately lock and unlock the line lock assembly, and
- wherein the line lock member comprises a line lock lever that pivots within a plane that is perpendicular to the axis of the reel to alternately lock and unlock the line lock assembly.
