Abstract

Abstract A conduit marking device including one or more strips of flexible material coupled adjacent one end to a fastening member configured for coupling to a conduit member. The strips, when coupled to the conduit member, extend in a vertical direction, with the strength and flexibility thereof being sufficient to avoid severing during the screeding process. The length of the strips is sufficient to extend above the surface of the poured concrete floor to provide visual indication of the location of the conduit member after curing of the concrete. The strips may be color coded, or may be provided with indicia, either or both of which may be used to indicate the type of conduit member, as well as the direction, depth or the like.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 122 words
A device for marking the location of conduit at or below the surface of a poured concrete floor, said device comprising: means for fastening the device to a portion of a conduit; generally flexible feather means for indicating the conduit location relative to the surface of said floor, said feather means being secured at approximate one end thereof to said fastening means, said feather means having a rigidity sufficient to withstand concrete finishing methods and having a length sufficient for a second end thereof to protrude, at least in part, above the surface of the concrete floor after finishing thereof; said feather means having adjustable means for slideable positioning and securing of selected ones of said feather means onto said fastening means.
Claim 2
Independent Claim 122 words
A device for marking the location of conduit at or below the surface of a poured concrete floor, said device comprising: means for fastening the device to a portion of a conduit; generally flexible feather means for indicating the conduit location relative to the surface of said floor, said feather means being secured at approximate one end thereof to said fastening means, said feather means having a rigidity sufficient to withstand concrete finishing methods and having a length sufficient for a second end thereof to protrude, at least in part, above the surface of the concrete floor after finishing thereof; said feather means having adjustable means for slideable positioning and securing of selected ones of said feather means onto said fastening means.
Claim 3
Dependent Claim 78 words
The device according to claim 1 wherein said selected ones of said feather means includes at least one set of a plurality of generally identical feather strip members all of which are secured to each other at said one end thereof to a common point; and said adjustable means including means for banding selected ones of said set of strip members together at a point intermediate said common point and a second end of said feather strip members.
Claim 4
Dependent Claim 47 words
The device according to claim 2 wherein said adjustable means is a slip tie banding certain of said strip members in belt loop fashion whereby said fastening means may be slipped through at least two of said strip members between said common point and said slip tie.
Claim 5
Dependent Claim 43 words
The device according to claim 2 wherein the strip members of said at least one set are oriented generally in the same direction fanning out toward said second end of said strip members, and selectively color coded to indicate the type of conduit.
Claim 6
Dependent Claim 25 words
THe device according to claim 4 wherein said banding means includes a slideable member configured for generally frictionally encompassing the set of said strip members.
Claim 7
Independent Claim 131 words
A device for marking the location of conduit at or below the surface of a poured concrete floor, said device comprising: strip means for fastening the device to a portion of a conduit; a plurality of sets of generally flexible generally identical feather strip members all of which are secured at one end thereof to said strip means, said strip members having a rigidity sufficient to withstand concrete finishing methods and having a length sufficient for a second end thereof to protrude, at least in part, above the surface of the concrete floor after finishing thereof; and means for banding said set of strip members together at a point intermediate said strip means and said second end of said strip members for enhancing the rigidity of said set of strip members.
Claim 8
Independent Claim 131 words
A device for marking the location of conduit at or below the surface of a poured concrete floor, said device comprising: strip means for fastening the device to a portion of a conduit; a plurality of sets of generally flexible generally identical feather strip members all of which are secured at one end thereof to said strip means, said strip members having a rigidity sufficient to withstand concrete finishing methods and having a length sufficient for a second end thereof to protrude, at least in part, above the surface of the concrete floor after finishing thereof; and means for banding said set of strip members together at a point intermediate said strip means and said second end of said strip members for enhancing the rigidity of said set of strip members.
Claim 9
Dependent Claim 31 words
The device according to claim 6 wherein said strip members of each set are secured to each other at said one end thereof to a common point on said strip means.
Claim 10
Dependent Claim 34 words
The device according to claim 6 wherein the strip members of all sets are oriented generally in the same direction and said strip members are selectively color coded to indicate the type of conduit.
