DETAILED DESCRIPTION OF THE INVENTION

Now referring to the drawings, the system for indexing tubing members in accordance with a first embodiment is shown and generally illustrated in FIGS. 1 and 2, while a second embodiment is provided in FIGS. 3 and 4, and a third embodiment is depicted at FIG. 5. Turning to FIG. 1, system for indexing tubing members generally includes an indexing card 10 having at least one receiver position 12 thereon and at least one end cap 14 received in the least one receiver position 12. Further, each of the end caps 14 and receiver positions 12 bear a unique identifier 16 that serves to match the end cap 14 to its receiver position 12 on the indexing card 10 facilitating the identification of a tubing member as will be described in more detail below.

Preferably, in the context of the present invention, the indexing card 10 includes a plurality of receiver positions 12 thereon and a corresponding plurality of end caps 14 is removably received within the receiver positions 12 on the indexing card 10. In practice, the plurality of end caps 14 are then employed one at a time by affixing the end cap 14 to a terminal end of a tubing member 18 before the tubing member 18 is installed into a structure as part of a larger system made up of a plurality of tubing members 18. For example, the tubing member 18 may be a polymeric tubing material, such as ethylene propylene diamine (EPDM) rubber, polyvinyl chloride (PVC), polyethylene (PE) or cross-linked polyethylene (PEX) as is typically used in commercial and residential construction for the installation of heating systems and the installation of potable water supply lines that require a plurality of tubing members 18 to function properly. Prior to the installation of each of the continuous runs of tubing members 18 that loop out and back around a building's structure, the end cap 14 is removed from the indexing card 10 and installed onto the leading terminal end of the tubing member 18. The tubing member 18 is then installed into the structure by threading the leading end of the tubing member 18 through a plurality of holes drilled in the structure between the desired service location and the point of origin for the heating system or water service. During the installation process each of the tubing members 18 is installed with their ends left hanging at a termination location where they are later attached to the correct system, be it a zone manifold for a heating system, the cold water supply or the hot water supply. Accordingly, when it is time to connect all of the loose ends of the tubing members 18 the installer can simply refer to the end cap 14 and correlate each end cap 14 with the correct receiver position 12 on the indexing card 10 thereby properly identifying the tubing member 18 in order to insure that they are correctly connected.

As was stated above, the indexing card 10 has a plurality of receiver positions 12 thereon in the form of holes that extend either fully or partially therethrough. The receiver positions 12 are sized and shaped to each receive and retain one of the plurality of end caps 14. The indexing card 10 also includes an identifier tag 16 adjacent each receiver position 12 such that the identifier tags 16 on the indexing card 10 correspond to an identical identifier tag 16 on the end cap 14 that is received in the receiver position 12. The identifier tag 16 is preferably alphanumeric (letters or numbers) but may also be a color code. Further, the identifier tag 16 may be a combination of numbers, letters and/or colors. For example, if the identifier tags 16 are letters as depicted in FIG. 1, A, B, C, . . . then each of the end caps 14 will include corresponding letters thereon. Similarly, if the identifier tags are numbers, 1, 2, 3, . . . then each of the end caps will include the corresponding number thereon and if the identifier tags are colors, red, blue, green, . . . then each of the end caps will include the corresponding color thereon. Finally, the indexing card 10 preferably includes a space adjacent the identifying tag 16 that allows the user to write relevant information corresponding to that particular receiver position 12 in order to assist with identify the tubing member 18 at a later date.

The indexing card 10 may be formed from any suitable material, but is preferably formed from a durable polymer material. The indexing card 10, as was stated above, has a plurality of receiver positions 12 thereon. The receiver positions 12 are shown in the first embodiment as holes extending therethrough but may also be formed as holes that extend only partially into the thickness of the indexing card 10 or as pegs that extend outwardly from the indexing card 10. The particular structure of the receiver positions 12 is not important, only that the receiver positions 12 include formations that are suitable for receiving and retaining the plurality of end caps 14 as will be described in detail below. The indexing card 10 also includes an identifier tag 16 adjacent each receiver position 12.

Turning to FIG. 2, it can be seen that the end caps are formed to have a head portion 22 and a tail portion 24. The head portion 22 has an outer diameter that corresponds to the outer diameter of the tubing member 18 and is preferably tapered or rounded in a manner that allows it to be easily threaded through a building structure as the tubing member 18 is installed. The tail portion 24, in this embodiment, is formed to be slightly larger than the inner diameter of the tubing member 18 so that it can be inserted and frictionally retained in the terminal, open end of the tubing member 18. In this embodiment, the tail portion 24 is received into the inner diameter of the tubing member 18. The end cap 14, once installed into the tubing member 18 serves to identify the tubing member 18 by allowing cross-referencing the identification tag 16 on the end cap 14 with the matching identification tag 16 on the indexing card 10. In addition, the end cap 14 also plugs the open end of the tubing member 18 to prevent entry of contaminants, to prevent the end of the tubing member 18 from being damaged and to prevent the end of the tubing member 18 from snagging on the structure during installation therethrough. It should be appreciated by one skilled in the art that end caps 14 and indexing card 10 will be manufactured to sizes that correspond to each of the typical tubing sizes that are used in such installations. When not in use, the end caps 14 are installed back into the corresponding receiver locations 12 on the indexing card 10.

In operation, a user employing a method in accordance with the present invention is presented with an indexing card 10 having a plurality of receiver positions 12 thereon and a plurality of end caps 14 received in each of the receiver positions 12, wherein each of the receiver positions 12 and end caps 14 include a unique matching identifier 16 associated therewith. The user selects one of the end caps 14 and removes it from the receiver position 12 on the indexing card 10. The user then installs the end cap 14 onto the terminal end of one of the tubing members 18 within a plurality of tubing members. Further, the user may elect to make a notation in the corresponding notation space 20 on the indexing card 10 relative to the tubing member 18 that is being installed, i.e. domestic cold-water 1^st floor bath. The tubing member 18 is then installed by fishing it through the building structure. The above process is then repeated for each of the tubing members 18 that need to be installed. Once the tubing members 18 are all installed, the user simply returns to the location where the terminal ends of the tubing members 18 are installed and identifies each tubing member 18 by the end cap 14 installed thereon, removes the end caps 14 as the terminal ends of the tubing members 18 are attached to the correct utility and then returns the end caps 14 to the receiver position 12 on the indexing card 10. It should also be appreciated by one skilled in the art that the end caps 14 may be provided in matching pairs such that one of the matching end caps 14 is installed on each of the ends of the length of the tubing member 18. This allows easy identification of the tubing member 18 from either end and allows each of the ends to be matched up with the indexing card 10.

Turning now to FIGS. 3 and 4, an alternate embodiment of the present invention is shown an illustrated. In this embodiment, the end caps 114 include a head portion 122 and a tail portion 124 that is configured to fit about the outer diameter of the tubing member 18. In this regard, the end cap 114 is installed onto the tubing member 18 such that the terminal end of the tubing member 18 is received into an opening in the tail portion 124 of the end cap 114. To receive and retain the end caps 114, the receiver positions 112 on the indexing card 110 are instead formed as protrusions that extend out from the surface of the indexing card 110 in contrast to the holes that were provided in the earlier embodiment. Further, it can be seen that the identification tags 116 in this particular embodiment are depicted as numbers instead of letters. In all other aspects, this embodiment of the present invention operates as described above.

Finally, FIG. 5 depicts another alternate embodiment indexing card 210 for use in conjunction with the alternate embodiment end caps 114 described above. In this regard, the indexing card 210 includes receiver positions 212 that protrude outwardly from the edge of the indexing card 210. In addition, the identification tags 216 in this embodiment are depicted as colors wherein the corresponding end cap 114 will be colored or bear a color band corresponding to the color designation on the indexing card 210.

It can therefore be seen that the present invention provides a method and system that facilitates the indexing and organization of the individual tubing members of a tubing system as they are installed into a structure. In this regard, the present invention provides a system that facilitates installation of the individual tubing members, protects them from damage, prevents the entry of debris into the tubing while also providing a convenient organizational system. For these reasons, the present invention is believed to represent a significant advancement in the art, which has substantial commercial merit.

While there is shown and described herein certain specific structure embodying the invention, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended claims.
