Abstract
Abstract A marker for ground areas has a hollow cylindrical rigid body with an open end and a closed end, the open end constituting the bottom and the closed end constituting the top when the marker is embedded in the ground. Such rigid body is forced under pressure into the ground by pressing it into the ground until the top wall is substantially level with the ground surface. The top wall is treated to present a prominent indicating surface, and, in the instance of the marker being used for golf courses, the top wall is formed from a resilient, plastic or elastomeric material that would be comparable to the natural ground surface insofar as ball reaction thereto in striking the same is concerned.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
140 words
A ground area marker specifically adapted for marking areas of a golf course comprising: (a) a hollow rigid body portion having opposing upper and lower ends with the lower end being open and being adapted to be inserted under pressure on the upper end into the ground so that the body portion is embedded up to its upper end into the ground; and, (b) means operatively attached to said open upper end for closing off the open upper end defining a ground level top wall for the body portion and being unsupported in the central portion of said open upper end, said means being constructed of an extremely flexible resilient plastic material so that a golf ball in striking the top wall would not unduly bounce but rather would react in the same fashion as when striking the surrounding ground.
Claim 2
Dependent Claim
140 words
A ground area marker specifically adapted for marking areas of a golf course comprising: (a) a hollow rigid body portion having opposing upper and lower ends with the lower end being open and being adapted to be inserted under pressure on the upper end into the ground so that the body portion is embedded up to its upper end into the ground; and, (b) means operatively attached to said open upper end for closing off the open upper end defining a ground level top wall for the body portion and being unsupported in the central portion of said open upper end, said means being constructed of an extremely flexible resilient plastic material so that a golf ball in striking the top wall would not unduly bounce but rather would react in the same fashion as when striking the surrounding ground.
Claim 3
Dependent Claim
38 words
The ground area marker of claim 1, wherein the upper end is open and is closed off by said means which is constituted by a elastomeric flat member overlyingly affixed to the upper end of the body portion.
Claim 4
Dependent Claim
37 words
The ground area marker of claim 1, wherein said means includes an integral top wall having an outer face provided with means to contrast it visually from the surrounding ground area in which it may be placed.
Claim 5
Dependent Claim
25 words
The ground area marker of claim 1, wherein said means includes a elastomeric closure member fixed over the upper end to close the same off.
Claim 6
Dependent Claim
33 words
The ground area marker of claim 4, wherein said closure member has an outer face provided with means to contrast it visually from the surrounding ground area in which it may be placed.
Claim 7
Dependent Claim
13 words
The ground area marker of claim 1, wherein said body portion is cylindrical.
