Abstract

A marker stake includes a ribbed spike having converging ribs directed towards a lowermost end for barring rotation of the spike, with the spike arranged for mounting an indicator shaft. The indicator shaft is arranged for removable mounting relative to the spike member, with a step plate arranged for removably mounting the organization relative to the spike member and the indicator shaft for indicating various geographical locations within a predetermined area.

Claims

1. A location marker stake, comprising,

a spike member, the spike member having a plurality of longitudinal ribs,

and

an abutment collar, the ribs extending from the abutment collar and canted towards one another terminating in a pointed distal end, the abutment collar further including a first side, with the ribs extending from the first side, and the abutment collar having a second side, with a mounting shaft extending from the second side, with the mounting shaft, the abutment collar, and the ribs coaxially aligned about a predetermined axis, with the abutment collar orthogonally oriented relative to the axis,

and

an indicator shaft, the indicator shaft having an indicator shaft first end, the first end including an indicator shaft socket, with the indicator shaft socket receiving the mounting shaft,

and

the indicator shaft having a second end,

and

a plurality of abutment pins fixedly mounted to the indicator shaft spaced from and adjacent the second end,

and

a flag tube, the flag tube including a flag member mounted thereon, the flag tube arranged for reception over the second end for engagement with the abutment pins and including a step plate, the step plate having a step plate tube, and the step plate tube positioned in engagement with the abutment collar receiving the indicator shaft therethrough at the first end.

2. A location marker stake as set forth in claim 1 including a plurality of spaced reflective bands mounted about the indicator shaft.

3. A location marker stake as set forth in claim 2 including a marker insert, the marker insert arranged to include a tubular housing, the housing having a housing first end including a lowermost socket, and a housing second end having an upper socket, the upper socket arranged for receiving the indicator shaft first end, and the lower socket arranged for receiving the mounting shaft, with a floor plate positioned within the housing adjacent the lower socket, and a piston positioned within the housing spaced from the floor plate, and a spring interposed between the piston and the floor plate defining a fluid cavity therebetween, and a plurality of nozzle tubes projecting radially and in fluid communication with the cavity, and canted downwardly from the cavity towards the lower socket, with each of the tubes having an exit port, and each exit port including a door plate, each door plate having a spring hinge to hingedly mount the door plate into sealing engagement with a respective exit port.

4. A location marker stake as set forth in claim 3 including a plunger rod in contiguous communication with the piston positioned between the piston and the upper socket, and the plunger rod including a plurality of foot rods extending from the plunger rod projecting laterally and radially of the marker insert, with each of the rods received within a slot, with each slot positioned within the tubular insert housing directed between the upper socket and the cavity.
