Abstract

A marking paint applicator for a portable electronic locator that locates buried cables and pipes via electromagnetic emissions is disclosed. The marking paint application may include an elongated support structure and a trigger mechanism, along with a bracket assembly, a receptacle for holding paint, and an actuating mechanism for selectively controlling release of the paint in response to operator actuation of the trigger mechanism.

Claims

1. A marking paint applicator for use with a portable locator, comprising:

an elongate support structure;

a mounting assembly for removable coupling of the applicator to the portable locator;

a trigger mechanism;

a receptacle mounted to the support structure for holding an aerosol paint can and positioning a valve stem of the aerosol paint can for spraying paint onto the ground; and

an actuating mechanism for controlling the valve stem so as to cause the aerosol paint can to spray paint for deployment on the ground.

2. The marking paint applicator of claim 1, wherein the mounting assembly comprises a bracket assembly for removably coupling the marking paint applicator to a housing of the portable locator.

3. The marking paint applicator of claim 1, wherein the mounting assembly comprises a bracket assembly for removably coupling the support structure to a mast of the locator.

4. The marking paint applicator of claim 1, wherein one or both of the receptacle and the support structure comprise a non-metallic material for minimizing magnetic field distortion of magnetic field signals received by the portable locator.

5. The marking paint application of claim 1, wherein the support structure and receptacle are formed as a single integrated unit.

6. The marking paint applicator of claim 1, wherein the receptacle comprises a plastic split semi-cylindrical holder that can be spread apart to receive an aerosol paint can in an inverted position and squeezably hold the paint.

7. The marking paint applicator of claim 1, further including a pair of wheels removable coupled to the support structure, with the wheels positioned below the lower end of the support structure.

8. The marking paint applicator of claim 1, wherein the triggering mechanism comprises a rigid plastic loop shaped to seat against the bottom of a handle element of the portable locator, with a trigger oriented to be actuated in an upward direction when gripped by a user around the portable locator handle.

9. The marking paint applicator of claim 1, wherein the triggering mechanism includes:

a position indicating element movable upon activation; and

a corresponding sensor for sensing movement of the position indicating element and providing a signal corresponding to the activation to the portable locator.

10. The marking paint applicator of claim 9, wherein the position indicating element is a permanent magnet and the sensor is a magnetic sensor.

11. The marking paint applicator of claim 1, further including a stencil including a cutout defining a pattern on the ground or other surface to be painted, and a collar positioned below the receptacle for retaining the stencil to allow paint to pass through the cutout.

12. The marking paint applicator of claim 1, wherein the support structure is a hollow tubular structure with the linkage disposed therein.

13. The marking paint applicator of claim 1, wherein the triggering mechanism comprises a rigid plastic loop shaped to seat against the bottom of a handle element of the portable locator, with a trigger oriented to be actuated in an upward direction when gripped by a user around the portable locator handle.

14. The marking paint applicator of claim 13, wherein the triggering mechanism further comprises:

a position indicating element movable upon activation; and

a corresponding sensor for sensing movement of the position indicating element and providing a signal corresponding to the activation to the portable locator.
