Attachment of a fabric sleeve to a communications cable

Abstract

An apparatus to be introduced into a conduit includes a cable and a fabric sleeve which extends longitudinally along the cable. The sleeve is secured around the cable by complimentary connectors which extend outwardly from the edges of the sleeve. The connectors can take the form of many configurations including a hook and slot, a ball and socket, a hook and loop, and zipper teeth, among others.

PREFERRED EMBODIMENTS FOR CARRYING OUT THE INVENTION

(7) One form of a sleeve made in accordance with the present invention is indicated generally by the numeral 10. An end view of sleeve 10 is shown in FIG. 1 with it being understood that sleeve 10 can be formed of a strip of material having a significant longitudinal length. Sleeve 10 is made up of a pliant, preferably fabric, sheet of material 11. A male connector, generally indicated by the numeral 12, extends outwardly from and is attached to one lateral edge 13 of fabric 11 by stitching, gluing or the like. A complementary female connector, generally indicated by the numeral 14, extends outwardly from and is attached to the opposed lateral edge 15 of fabric 11 by sewing, gluing or the like.

(8) Male connector 12 can be made of a somewhat flexible metallic or plastic material and includes a base portion 16 extending generally laterally outwardly from edge 13 of fabric 11, and a hook portion 17 which extends angularly upwardly and laterally inwardly from the lateral edge of base portion 16.

(9) Female connector 14 can be made of a somewhat flexible metallic or plastic material and includes a base portion 18 extending generally laterally outwardly from edge 15 of fabric sheet 11, and a receiving portion generally indicated by the numeral 19. Receiving portion 19 includes a portion 20 extending angularly upwardly and laterally outwardly from edge 15, and an engagement portion 21 extending downwardly toward base portion 18 from the outer end of portion 21. An opening 22 is formed between the lower end of engagement portion 21 and base portion 18 of female connector 14.

(10) FIG. 2 shows sleeve 10 engaging a conventional cable 23. As such, fabric sheet 11 can be positioned around cable 23, and the male connector 12 is inserted through opening 22 of female connector 14. The tip of hook portion 17 then engages the engagement portion 21 of female connector 14, resulting in the sleeve 10 being attached to cable 23. The lateral width of the fabric sheet 11 can be selected dependent on the size of the cable such that when the fabric 11 is positioned around the cable and the male and female connectors 12, 14 are engaged, the sleeve 10 is attached to cable 23.

(11) FIG. 3 depicts an alternate configuration for the sleeve connectors. There, a sleeve, generally indicated by the numeral 30, includes a sheet of fabric material 31 having a male connector 32 extending outwardly from, and attached to, one lateral edge 33, and a complementary female connector 34 attached to and extending outwardly from the opposed edge 35. The male connector is in the form of a ball 36, and the female connector is in the form of a somewhat resilient socket 37. When sleeve 30 is engaging a cable, such as cable 23, ball 36 is engaged by socket 37 to hold sleeve 30 around the cable.

(12) FIG. 4 depicts another alternative configuration for the sleeve connector. There, a sleeve, generally indicated by the numeral 40, includes a sheet of fabric material 41 having a connector 42 attached to and extending outwardly from one lateral edge 43, and a complimentary connector 44 attached to and extending outwardly from the outer lateral edge 45 of fabric sheet 41. One of the connectors 42, 44 can be in the form of the hook portion of a conventional VELCRO configuration, which is carried by an extension of sheet 41 extending outwardly beyond edge 43, and the other connector 42, 44 can be in the form of the complementary loop portion of the VELCRO configuration, which is carried by an extension of sheet 41 extending outwardly beyond edge 45. As shown in FIG. 4, the connectors 42, 44 face the same side of the sheet of material 41 such that when sleeve 40 is wrapped around a cable 23, as shown in FIG. 6, the connection of the hooks and loops 42, 44 form with the extensions of sheet 41, a tab or ear 46 which extends longitudinally along cable 23.

(13) In another embodiment, shown in FIG. 6, a sleeve, generally indicated by the numeral 50, includes a longitudinally extending sheet of fabric material 51 having complementary zipper teeth 52, 53 extending outwardly from opposed lateral edges 54, 55 of sheet 51, respectively. One set of zipper teeth such as 52, are provided with a conventional zipper pull 56 such that when sleeve 50 is wrapped around a cable, the zipper pull may mesh the zipper teeth in a conventional manner to engage the cable with the sheet 51.

(14) By whatever manner a fabric sleeve is attached to a cable, once positioned around a cable, the sleeve protects the casing of the cable when being installed into a conduit or when another cable is being installed in a conduit already having a fabric-wrapped cable therein. Thus, the cable casings see no friction, and not only are the fabric-wrapped cables easier to install, but also the cables are protected from potential damage during installation.

(15) It should thus be appreciated that a sleeve attached to a cable as described herein substantially improves the art and otherwise accomplishes the objects of the invention.
