Appeal 2007-2121
Application 10/705,083
1. In combination, a grading marker stake with an integral impact
head and a driver which, together with the stake, form an integral point
driver system, comprising:
a stake body formed in one piece of a lightweight synthetic polymeric
material, the stake body having a length, a bottom end which terminates in a
bottom end opening, an intermediate sidewall portion and a top end which
terminates in a top end opening;
a driver having a stepped cylindrical body including a drive shoulder
located along a length thereof between a drive end and an oppositely
arranged pointed end of the body;
wherein the stake body has a cylindrical sidewall portion which is
joined to the top end by a performed frusto-conical [sic] wall region which
also defines a top, planar exposed end surface, and wherein the planar
exposed end surface has an outer periphery, the outer periphery being of a
larger relative diameter than the diameter of the cylindrical sidewall portion
of the stake body, the top, planar exposed surface being selectively sized to
receive the driver shoulder of the pointed shaft driver for driving the stake
into the surrounding terrain;
wherein the top, planar exposed surface comprises a reinforced upper
end of the stake body, also integrally formed of the synthetic polymeric
material, for receiving impact forces from the driver; and
wherein the stake body has a hollow interior bore which
communicates the top and bottom end openings, the interior bore being sized
to closely receive a portion of the cylindrical body of the driver with the
driver pointed end extending at least slightly from the bottom end of the
stake body, whereby the stake can be retained frictionally on the driver to
allow a user to drive a stake into the surrounding terrain without the
necessity of bending.
9. In combination, a grading marker stake with an integral impact
head, an end cap, and a driver which, together with the stake, form having an
integral point driver system, comprising:
a stake body formed in one piece of a lightweight synthetic polymeric
material, the stake body having a bottom end which terminates in a bottom
end opening, an intermediate sidewall portion and a top end which
terminates in a top end opening;
