Abstract
Embodiments of a sheath for a pointed tool are described, which tool may be a combination string/chalk line anchor and plumb bob. The sheath includes a cavity for housing the pointed needle or spike that extends out from the combination tool, and a cavity for at least partially encircling the body of the tool. A locking mechanism is included to secure the tool in the sheath until removed is desired. The sheath may include a system for attaching it to a chalk box, and a slot defining an exit-point for string line to extend out from the sheath to the chalk box or other container or spool.
Claims17
A sheath and string-line tool combination comprising:
- a tool having a tool body with a front end and a recess, a pointed member protruding from the front end, and a string having a first end and a second end, the first end being attached to the tool;
- a sheath having a sheath front end and a sheath rear end, a longitudinal axis between said sheath front end and said sheath rear end, a cavity wall surrounding and defining an interior cavity with an opening receiving the tool, wherein the interior cavity has a forward portion receiving the pointed member and a rearward portion receiving at least a part of the body of the tool;
- a locking system adapted to releasably lock the tool in the sheath, the locking system comprising a latch that is biased to extend into said recess of the tool body to prevent removal of the tool from the sheath.
A tool sheath and chalk box combination comprising:
- a sheath for a string-line anchor tool having a tool body, a pointed member and a string, the sheath having a sheath front end and a sheath rear end, a longitudinal axis between said sheath front end and said sheath rear end, a cavity wall surrounding and defining an interior cavity with an opening adapted to receive the anchor tool, wherein the interior cavity has a forward portion adapted to receive the pointed member and a rearward portion adapted to receive at least a part of the tool body;
- a locking system adapted to releasably lock the anchor tool in the sheath;
- and
- a chalk box containing chalk for coating the string of the anchor tool;
- wherein the sheath is attached to the chalk box.
A sheath system for a combination string-line anchor and plumb bob tool, the tool having a tool body and a pointed spike extending forward from the tool body and a string extending from the tool, the sheath system comprising:
- a sheath having a sheath front end and a sheath rear end, a longitudinal axis between said sheath front end and said sheath rear end, a cavity wall surrounding and defining an interior cavity with an opening adapted to receive the tool, wherein the interior cavity has a forward portion adapted to receive the pointed spike and a rearward portion adapted to receive at least a part of the body of the tool;
- a locking system adapted to releasably lock the tool in the sheath, the locking system comprising a lock member connected to the cavity wall and that is pivotal in a plane parallel to the longitudinal axis of the sheath, the lock member having a rearward latch end and a forward handle end, wherein the lock member is biased to place the rearward latch end generally across a portion of the opening for extending into a recess of the tool body rearward of the opening to prevent removal of the tool from the sheath, and wherein the forward handle end is adapted, when pressed toward the cavity wall, to pivot the lock member so that the rearward latch end rises away from the opening.
