  • Patent number: 6085452
    Abstract: A device and method for marking a location with a marker stake. An elongate wire-like rod is partially inserted in the ground at a location to be marked, and the rod is received in a pre-sized panel having a pair of flag faces and an open-ended longitudinal channel, the channel being dimensioned to receive the rod in friction fit. The flag faces are separated by a plurality of spacers in generally parallel orientation to each other, with the spacers defining the plurality of channels, and the panel has two longitudinal ends each having a sighting notch. While inserting the rod into the ground, the panel may be disposed at the ground to serve as a guide to retain the rod against deflection. Two or more panels and rods may be joined together to produce a larger marker stake, and the panels may be oriented at right angles to each other to give the marker stake a greater three-dimensional profile.

  • Patent number: 4894937
    Abstract: A stake for holding a sign upright and comprising at least two parallel and spaced-apart elongate legs, one end of which legs for being driven into the ground and the other end of which legs for supporting a sign above the ground, and at least two longitudinally spaced-apart cross-members secured to and connecting the legs together. At least one of the cross-members comprises a step for being used to drive the two legs into the ground for supporting a sign on the other end. The other end of the legs comprises thin wire-like members for extending into the open areas of a corrugated sign or for holding a fiberboard sign. The other cross-member supports the sign at a predetermined distance above the cross-member which comprises the step.
