Marker post system
First Claim
1. A boundary marking system of the type including a hollow, tubular receptacle of rigid weatherproof material having a longitudinal axis and adapted to be set in the ground with the upper open end at ground level, a weatherproof, essentially planar surface plate of substantially greater diameter than the receptacle disposed in surrounding relationship with the upper open end of the receptacle essentially at ground level, and a marker stake having a longitudinal axis parallel to the axis of the receptacle, removably disposed in the receptacle extending above ground level, wherein the improvement comprises:
- swivel means interconnecting the receptacle and plate for varying the relative angular relationship between the plate and the axis of the receptacle so that the plate may lie flush with a non-level ground surface and nonperpendicular to said axis.

Abstract
A marker for golf courses and similar locations including an in-ground receptacle, a surface plate mounted on and in surrounding relationship with the top of the receptacle at ground level, and a tubular "stake" which fits into the receptacle. The plate and receptacle form a swivel bearing to permit the surface plate to lie flush with non-level ground while retaining the vertical orientation of the stake and receptacle. The plate is crowned to shed balls.

12. A boundary marking system comprising:
-
a hollow tubular receptacle having a longitudinal axis; a marker stake, having a longitudinal axis coaxially aligned with the longitudinal axis of the receptacle, removably and contiguously disposed in the receptacle; a surface plate of substantially greater diameter than the receptacle; and a swivel means interconnecting the receptacle and surface plate for varying the relative angular relationship between the surface plate and the respective longitudinal axes of the receptacle and marker stake. - View Dependent Claims (13, 14, 15, 16)

17. A boundary marking system comprising:
-
a hollow tubular receptacle having a longitudinal axis, the receptacle further including a semi-spherical external bearing seat formed on the receptacle adjacent the upper open end thereof; a marker stake having a longitudinal axis coaxial with the longitudinal axis of the receptacle, removably and contiguously disposed in the receptacle; and an essentially planar surface plate of substantially greater diameter than the receptacle, said surface plate further including a semi-spherical internal bearing seat formed centrally on said surface plate, said internal bearing seat coacting with the external bearing seat of the receptacle to vary the relative angular relationship between the surface plate and the coaxial longitudinal axes of the receptacle and marker stake.
