Abstract

A duct for distributing one or more telecommunication lines comprises an elongated body having a length and a conduit portion with a lengthwise bore formed therein. The conduit portion contains one or more telecommunication lines. The duct also includes a flange extending lengthwise adjacent the main body to mount the duct to a mounting surface, such as a wall. The duct also includes an adhesive layer disposed on a surface of the flange, the adhesive layer comprising a removable adhesive to permit removal of the duct from the mounting surface after mounting.

Claims

1. A duct for distributing one or more communication lines, comprising:

an elongated body having a length and a conduit portion with a lengthwise bore formed therein, the conduit portion containing one or more communication lines;

a flange extending lengthwise adjacent the elongated body to mount the duct to a mounting surface; and

an adhesive layer disposed on a surface of the flange, the adhesive layer comprising a removable adhesive to permit removal of the duct from the mounting surface after mounting.

3. The duct of claim 1, wherein the adhesive layer comprises a stretch release adhesive.

4. The duct of claim 3, wherein the stretch release adhesive comprises one of an acrylic-based adhesive, a rubber-based adhesive, and a silicone-based adhesive.

7. The duct of claim 3, wherein the stretch release adhesive comprises a highly extensible backing.

9. The duct of claim 1, wherein the elongated body has a form factor (length versus width) of at least 25 to 1.

12. The duct of claim 1, wherein the duct includes at least one additional conduit, wherein the first conduit is configured to contain at least a first optical fiber communication line and the additional conduit is configured to contain at least a second optical fiber communication line.

13. The duct of claim 1, wherein the one or more communication lines includes an electrical wire.

14. The duct of claim 1, wherein the adhesive layer comprises first and second adhesive layers each disposed on a different portion of the surface of the flange.

15. The duct of claim 1, wherein the one or more communication lines comprises a high speed Ethernet communication line.

16. A removably mountable article, comprising:

an article having an elongated body having a form factor (length versus width) of at least 25 to 1 and a bottom surface along a length of the elongated body; and

an adhesive layer disposed on the bottom surface of the article, the adhesive layer comprising a removable adhesive to permit removal of the article from a mounting surface after mounting.

17. The removably mountable article of claim 16, wherein the elongated body is formed from a flexible material.

18. The removably mountable article of claim 16, wherein the elongated body is formed from a material that is at least substantially rigid.

19. The removably mountable article of claim 16, wherein the elongated body has a form factor (length versus width) of at least 50 to 1.

21. The removably mountable article of claim 16, wherein the adhesive layer comprises a stretch release adhesive.

22. The removably mountable article of claim 21, wherein the stretch release adhesive comprises one of an acrylic-based adhesive, a rubber-based adhesive, and a silicone-based adhesive.

25. The removably mountable article of claim 21, wherein the stretch release adhesive comprises a highly extensible backing.

27. A method of removing a duct mounted to a mounted surface, the duct including an elongated body having a length and a conduit portion with a lengthwise bore formed therein containing one or more communication lines, a flange extending lengthwise adjacent the elongated body, and an adhesive layer disposed on a surface of the flange, the adhesive layer comprising a removable adhesive, comprising:

stretching a portion of the adhesive layer in a lengthwise direction substantially along a plane of the mounting surface; and

pulling the portion of the adhesive layer away from the duct at a substantial angle from the lengthwise direction along the plane of the mounting surface.

28. The method of claim 27, wherein the substantial angle is at least 30°

from the lengthwise direction.

29. The method of claim 27, wherein the substantial angle is from about 45°

to about 135°

from the lengthwise direction.

32. The method of claim 27, further comprising;

pulling the portion of the adhesive layer away from the duct at a substantial angle away from the plane of the mounting surface.
