Abstract
Abstract An improved sprinkler protector comprises a rigid, selfsupporting body having an upper recess to wholly enclose a sprinkler head, a transverse lower aperture to enclose a sprinkler connector and a small diameter central standpipe passageway interconnecting the recess and aperture. Detent means are provided in the area of the recess to prevent substantial depression of the sprinkler head and rupture of the sprinkler system adjacent the connector. Reinforcing means and anchoring means for the protector body may also be provided.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
137 words
An improved sprinkler protector comprising: a rigid self-supporting body having relatively flat, generally horizontally extending top and bottom surfaces and an interconnecting side surface; the upper end of said body defining a generally centrally disposed recess extending down from said top surface and adapted to receive a fluid sprinkler head wholly therein; the lower end of said body defining an aperture having an open bottom extending across the width of said body and adapted to receive a sprinkler connector; said body further defining a generally centrally disposed, generally vertically extending passageway communicating with said aperture and said recess and adapted to receive a standpipe interconnecting said connector and said sprinkler head; said body further including in the area of said recess a sprinkler head detent which prevents substantial downward displacement of said head relative to said protector.
Claim 2
Dependent Claim
137 words
An improved sprinkler protector comprising: a rigid self-supporting body having relatively flat, generally horizontally extending top and bottom surfaces and an interconnecting side surface; the upper end of said body defining a generally centrally disposed recess extending down from said top surface and adapted to receive a fluid sprinkler head wholly therein; the lower end of said body defining an aperture having an open bottom extending across the width of said body and adapted to receive a sprinkler connector; said body further defining a generally centrally disposed, generally vertically extending passageway communicating with said aperture and said recess and adapted to receive a standpipe interconnecting said connector and said sprinkler head; said body further including in the area of said recess a sprinkler head detent which prevents substantial downward displacement of said head relative to said protector.
Claim 3
Dependent Claim
45 words
The improved sprinkler protector of claim 1 wherein said body is a solid, unitary body; wherein said recess, aperture and passageway are generally tubular; wherein said aperture is adapted to wholly enclose a T-connector, and wherein said passageway is smaller in diameter than said recess.
Claim 4
Dependent Claim
40 words
The improved protector of claim 1 wherein said detent comprises a generally cylindrical shelf defining a portion of said recess adjacent the bottom end thereof and adapted to support the bottom of a sprinkler head when said head is depressed.
Claim 5
Dependent Claim
21 words
The improved sprinkler protector of claim 1 wherein said detent comprises resilient support means disposed below said head in said recess.
Claim 6
Dependent Claim
30 words
The improved sprinkler protector of claim 1 wherein said protector includes resilient means disposed in said aperture adjacent the bottom thereof to cushion said connector during depression of said head.
Claim 7
Dependent Claim
22 words
The improved sprinkler protector of claim 1 wherein the lower end of said body includes a plurality of downwardly directed leg projections.
Claim 8
Dependent Claim
24 words
The improved sprinkler protector of claim 2 wherein a reinforcing element is disposed around said side surface adjacent the upper end of said body.
Claim 9
Dependent Claim
21 words
The improved sprinkler protector of claim 7 wherein a reinforcing element is also disposed adjacent the lower end of said body.
Claim 10
Dependent Claim
36 words
The improved sprinkler protector of claim 7 wherein said body is frusto-conical and fabricated of cast cementitious material and wherein said reinforcing element comprises a steel ring embedded in said body at the upper end thereof.
Claim 11
Dependent Claim
59 words
The improved sprinkler protector of claim 1 wherein said body has at least one substantially flat side adjacent the passageway, said flat side spaced from the center of the passageway by approximately the radius of a conventional sprinkler head and connecting with one edge of said recess, for permitting the installation of said protector adjacent a sidewalk or curb.
