Abstract:
A chalk stick holder device having a handle portion, a hollow central tube portion, and a gripper portion. The three portions can be joined together to form a long-reaching chalk stick holder for drawing on surfaces while the user remains standing. The gripper portion includes a spring-action receiver for receiving a chalk stick and securing the chalk stick within the gripper end using a locking tooth. Upon pressing the locking tooth, the receiver releases the chalk stick, which can then be replaced with another color of chalk stick stored in the hollow central tube portion.

Claim (Index 5):
A chalk stick holder device comprising:\n a receiver having an opening in a proximal end of said receiver, said opening configured for receiving a chalk stick; said receiver having a hollow body for holding said chalk stick within; a spring clip affixed to said receiver via a spring hinge, said spring clip having a front end configured to be raised to an engaged position wherein it locks said chalk stick within said receiver, and wherein said spring clip further configured to be lowered to a released position wherein said chalk stick is unlocked within said receiver; a locking tab comprising a plurality of teeth, said locking tab configured to lock said spring clip into said engaged position by receiving said spring clip within one of said plurality of teeth; said locking tab further configured to be drawn toward a distal end of said receiver, thereby allowing said spring clip to be lowered to said released position; said locking tab affixed to said receiver via a pin hinge; a hollow tube body having a proximal end and a distal end; said proximal end of said hollow tube body removable engaging said distal end of said receiver; said hollow tube body configured for extending the reach of the chalk stick holder device; said hollow tube body is configured to receive and store at least one additional chalk stick; a handle element affixed to said distal end of said hollow tube body; and said handle element providing a grippable surface.
