Abstract
Abstract An apparatus including a main support block of a generally parallelepiped cross-sectional configuration defined by a central bore directed therethrough, wherein the central bore receives and protects a sprinkler head in a surrounding relationship and wherein the central bore includes a knock-out section of the central bore to enlarge the central bore to increased area to receive a larger sprinkler head therewithin. The invention includes a modification wherein the main support block includes a secondary support block structure to permit stacking, with the secondary support block including projections at corners of the support block directed downwardly therefrom receivable within registration bores coaxially aligned with the projections to permit stacking of the organization to a predetermined height. The secondary support block may be formed of an absorbent stone or polymeric to permit absorption of various chemicals such as weed killer and the like to limit weed and grass growth overlying the organization.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
161 words
A sprinkler head guard apparatus comprising, a main support block, including a top surface spaced from and parallel to a bottom surface, and a central cylindrical bore orthogonally directed through the block extending from the top surface through the bottom surface, and a tubular sleeve removably mounted within the block coaxially aligned and in surrounding relationship relative to the central cylindrical bore extending from the top surface through the bottom surface, wherein the central cylindrical bore accepts a sprinkler head in a surrounding relationship relative thereto, and wherein the support block includes a plurality of first registration bores directed orthogonally and downwardly from the top surface and spaced a predetermined spacing from the central cylindrical bore, and the first registration bores spaced apart an equal distance relative to one another, and the main support block further including a series of first projections extending orthogonally and downwardly from the bottom surface of the support block coaxially aligned with the first registration bores.
Claim 2
Dependent Claim
161 words
A sprinkler head guard apparatus comprising, a main support block, including a top surface spaced from and parallel to a bottom surface, and a central cylindrical bore orthogonally directed through the block extending from the top surface through the bottom surface, and a tubular sleeve removably mounted within the block coaxially aligned and in surrounding relationship relative to the central cylindrical bore extending from the top surface through the bottom surface, wherein the central cylindrical bore accepts a sprinkler head in a surrounding relationship relative thereto, and wherein the support block includes a plurality of first registration bores directed orthogonally and downwardly from the top surface and spaced a predetermined spacing from the central cylindrical bore, and the first registration bores spaced apart an equal distance relative to one another, and the main support block further including a series of first projections extending orthogonally and downwardly from the bottom surface of the support block coaxially aligned with the first registration bores.
Claim 3
Dependent Claim
14 words
An apparatus as set forth in claim 1 wherein the first projections are conical.
Claim 4
Dependent Claim
206 words
An apparatus as set forth in claim 2 further including a secondary support block, wherein the main support block is defined by a predetermined height and the secondary support block is defined by a further predetermined height less than the predetermined height, and the secondary support block is defined by a secondary top surface and a secondary bottom surface of a substantially equal configuration relative to the top surface and the bottom surface respectively of the main support block, and the secondary support block including secondary registration bores directed orthogonally and downwardly from the secondary top surface, and further including secondary projections extending orthogonally and downwardly from the secondary bottom surface of the secondary support block, the secondary projections of a conical configuration and coaxially aligned with the secondary registration bores, and a secondary central cylindrical bore directed medially and coaxially through the secondary support block coextensive with the central cylindrical bore of the main support block, and the secondary registration bores and the secondary projections spaced from the secondary cylindrical bore the predetermined spacing, and the secondary registration bores and the secondary projections coaxially aligned with the first registration bores and the first projections when the secondary projections are received within the first registration bores.
Claim 5
Dependent Claim
45 words
An apparatus as set forth in claim 3 wherein the first registration bores are defined by a first registration bore diameter, and the secondary projections are of a conical configuration whose base diameter is substantially equal to a diameter defined by the first registration bores.
Claim 6
Dependent Claim
35 words
An apparatus as set forth in claim 4 wherein the secondary support block is formed of an absorbent polymeric material to permit absorption of lawn chemicals minimizing undesirable vegetations growth about a secondary support block.
