Abstract

A chalk box may include 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 configured to be wound on 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, and a seating assembly configured to extend around at least fifty percent of the length or volume of the end hook when the string is fully withdrawn into the housing.

First claim

That which is claimed:

1. 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 a second end wound on the reel assembly to extend from the housing through the aperture;
a chalk reservoir formed in a portion of the housing and in which the string is retained or through which the string passes prior to extending out of the aperture; and
a seating assembly extending around at least fifty percent of a length or volume of the end hook when the string is fully withdrawn into the housing.

2. The chalk box of claim 1 , wherein the seating assembly is operably coupled to the housing such that the string extends radially outwardly from the reel assembly through the aperture and into the seating assembly.

3. The chalk box of claim 2 , wherein the seating assembly comprises a reception cavity bounded by four sidewalls, and wherein a base of the end hook is substantially entirely surrounded by the four sidewalls when the string is fully withdrawn into the housing.

4. The chalk box of claim 2 , wherein each of the four sidewalls tapers inwardly toward the aperture over at least a portion of the sidewalls.

5. The chalk box of claim 1 , wherein the housing comprises a first case half and a second case half, and wherein the seating assembly is joined to the first and second case halves via a press fitting.

6. The chalk box of claim 1 , wherein the seating assembly comprises two opposing sides separated by a recessed area, and
wherein the end hook is retained in the recessed area when the string is fully withdrawn into the housing.

7. The chalk box of claim 6 , wherein the end hook is disposed entirely below a plane extending over a top of the opposing sides of the overmold portion when the string is fully withdrawn into the housing.

8. The chalk box of claim 1 , wherein the end hook comprises a base having a front side and a back side,
wherein prongs of the end hook extend substantially perpendicularly away from the front side, and
wherein the front and back sides of the end hook each lie in a plane that extends substantially perpendicular to an axis of the reel assembly when the string is fully withdrawn into the housing.

9. The chalk box of claim 8 , wherein the front and back sides of the end hook are tapered as the end hook extends toward the string.

10. The chalk box of claim 9 , wherein the seating assembly comprises a reception cavity, and wherein the reception cavity is tapered to substantially match a shape of the front and back sides of the end hook.

11. 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 a second end wound on the reel assembly to extend from the housing through the aperture;
a chalk reservoir formed in a first portion of the housing and in which the string is retained or through which the string passes prior to extending out of the aperture; and
a seating assembly disposed at a second portion of the housing extending around at least a portion of a length or volume of the end hook when the string is fully withdrawn into the housing,
wherein the seating assembly comprises a first case half and a second case half, and
wherein the seating assembly is conformal with the first portion of the housing.

12. The chalk box of claim 11 , wherein the seating assembly is operably coupled to the housing such that the string extends radially outwardly from the reel assembly through the aperture and into the seating assembly.

13. The chalk box of claim 12 , wherein the seating assembly comprises a reception cavity bounded by four sidewalls, and wherein a base of the end hook is substantially entirely surrounded by the four sidewalls when the string is fully withdrawn into the housing.

14. The chalk box of claim 12 , wherein each of the four sidewalls tapers inwardly toward the aperture over at least a portion of the sidewalls.

15. The chalk box of claim 11 , wherein the housing comprises a first case half and a second case half, and wherein the first and second case halves of the seating assembly conform to the first and second case halves of the housing.

16. The chalk box of claim 11 , wherein the seating assembly comprises two opposing sides formed of molded plastic and separated by a recessed area, and
wherein the end hook is retained in the recessed area when the string is fully withdrawn into the housing.

17. The chalk box of claim 16 , wherein the end hook is disposed entirely below a plane extending over a top of the opposing sides of the overmold portion when the string is fully withdrawn into the housing.

18. The chalk box of claim 11 , wherein the end hook comprises a base having a front side and a back side,
wherein prongs of the end hook extend substantially perpendicularly away from the front side, and
wherein the front and back sides of the end hook each lie in a plane that extends substantially perpendicular to an axis of the reel assembly when the string is fully withdrawn into the housing.

19. The chalk box of claim 18 , wherein the front and back sides of the end hook are tapered as the end hook extends toward the string.

20. The chalk box of claim 19 , wherein the seating assembly comprises a reception cavity, and wherein the reception cavity is tapered to substantially match a shape of the front and back sides of the end hook.
