A chalk reel has a housing defining a chalk chamber and an opening for accessing the chamber. A door is movable between an open position for allowing access through the opening to the chalk chamber and a closed position preventing access to the chamber. A lock assembly is provided on the door and is movable with the door. The lock assembly rotates relative to the door between a locked position and an unlocked position and reciprocates to secure and release a lock member.

A chalk line apparatus with a housing having a body with a top, a bottom, a front, a rear, and laterally spaced sides. The body defines an internal space within which a spool is operatively mounted. A drive assembly is operable through an actuator to cause line to be accumulated on the spool through a fill opening on the housing. A supply of chalk can be introduced into the internal space to contact the line. A stopper assembly can be selectively placed in closed and open states. The stopper assembly has a blocking portion that: a) blocks passage of chalk through the fill opening with the stopper assembly in the closed state; and b) permits chalk to be directed through the fill opening and into the internal space with the stopper assembly in the open state. The stopper assembly is adjacent to the drive assembly actuator.

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.

An end hook may include a stem portion extending in a first plane from a proximal end to a distal end and an engaging portion. The end hook may be operably coupled to the measuring device at the proximal end. The engaging portion may be defined by a set of teeth having external lateral edges that define a hook width therebetween. The engaging portion may extend away from the stem portion by an engaging length. Each of the teeth may include a portion thereof that extends away from the distal end of the stem portion in a second plane that is substantially perpendicular to the first plane. Each of the teeth may further include a portion thereof, proximate to a distal end of the teeth, that bends out of the second plane to form an engaging angle. The hook width may be in a range between about 16.5 mm and about 21 mm, and the engaging angle may be greater than about 45 degrees.

A chalk port for retaining chalk within a chalk reservoir of a chalk box may include an interface portion configured to interface with a housing of the chalk box to retain the chalk port in contact with the chalk box, a tapered portion extending away from the interface portion in an axial direction, and a slit assembly disposed at the tapered portion. The tapered portion may have a diameter that reduces as distance from the interface portion increases. The tapered portion may include a plurality of projections separated from each other by slits of the slit assembly. The projections may have a rest position configured to bias the slit assembly closed. Ribs may be formed to extend between the interface portion and the projections to bias the projections to the rest position.

A Handheld All-Terrain Chalker of the present invention is designed to create straight chalk lines on all types of surfaces. The Handheld All-Terrain Chalker works independent of the the surface in which the chalk lines are to be drawn and are unaffected by the variations of the surface. The Handheld All-Terrain Chalker includes a chalk hopper and a removable ergonomic handle. The chalk hopper is a semi-circular bucket having a storage container integrally formed with a dispenser. The storage container has an opening to allow the insertion of chalk. The dispenser is formed with a bottom having circular perforations or slotted openings to allow chalk to be dispensed to draw the chalk lines. To control the amount of chalk being dispensed and the width of the chalk line, a gasket or an adjustable chalk line plate is used to regulate the opening of the dispenser.
