Abstract

A chalk holding device for marking up dry walled walls of a building uses a pole that has a chalk holder at one end wherein chalk is received within the holder and locked in place via a compression ring. The pole may be threadably attached to an additional extension pole on the end opposite the chalk holding end. A light source is attached to the pole either by clamping the light source and attaching the clamp to the pole via another clamp, via adhesion or welding, or other appropriate attachment method, or the light source is an LED ring such that the pole passes through a central opening of the LED ring with the ring attached to the pole.

Claims (7)

1. A holding device comprising:

a pole member having a first end and a second end and a medial section therebetween;

a piece of chalk;

a receiver having a compression ring and an extension, the extension located on the first end, the receiver removably receiving the piece of chalk therein such that the compression ring, when rotated, firmly grips and holds the chalk within the receiver, and the compression ring, when counterrotated, releases its grip on the chalk; and

a light source attached to medial section of the pole member, the light source issuing a light beam in a direction that is the same as a longitudinal axis of the chalk; and wherein the light source comprises an LED ring having a central opening and a plurality of LEDs located around an outer periphery, such that the medial section of the pole member passes through the central opening in order for the LED ring to encompass the medial section of the pole member.

2. The holder as in claim 1 further comprising a threaded coupler attached to the second end of the pole member.

3. The holder as in claim 1 wherein the central opening has a first diameter and the medial section of the pole has a second diameter that is similar to the first diameter.
