DETAILED DESCRIPTION

(9) The present invention is described with reference to the accompanying drawings, in which certain embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments that are pictured and described herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. It will also be appreciated that the embodiments disclosed herein can be combined in any way and/or combination to provide many additional embodiments.

(10) Unless otherwise defined, all technical and scientific terms that are used in this disclosure have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the below description is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in this disclosure, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that when an element (e.g., a device, circuit, etc.) is referred to as being “connected” or “coupled” to another element, it can be directly connected or coupled to the other element or intervening elements may be present. In contrast, when an element is referred to as being “directly connected” or “directly coupled” to another element, there are no intervening elements present.

(11) Referring now to FIGS. 4-7, an adapter for mounting cable hangers, designated broadly at 100, is shown therein. The adapter 100 includes a floor 102, a ceiling 104 opposite the floor 102, and two side walls 106 that span the floor and the ceiling 104. As can be seen in FIG. 5, the floor 102 is narrower in width than the ceiling 104, such that each of the side walls 106 defines a trapezoidal or “wedge” shape. Four feet 108a-108d extend from the floor 102; in the illustrated embodiment, the feet 108a, 108b are located at two of the corners of the floor 102, whereas the feet 108c, 108d are located on the opposite edge from the feet 108a, 108b but are offset somewhat from the side walls 106 (in other embodiments, all four feet 108a-d may be located at the four corners of the floor 102). As shown in FIG. 4, the ceiling 104 includes a central hole 110; in some embodiments, the hole 110 is nominally ¾ inch in diameter, and thus is sized for the insertion of cables hangers such as that shown at 20 in FIG. 2. Parallel reinforcing ribs 112 are also present on the ceiling 104.

(12) The adapter 100 also includes a cross-member 114 that extends between the side walls 106 near the floor 102. A divider 116 extends between the cross-member 114 and the floor 102. The floor 102, cross-member 114 and divider 116 create two windows 118.

(13) In some embodiments, the adapter 100 is formed of a polymeric material, such as acetal, polyethylene, polypropylene, PVC, or the like. The adapter 100 may be formed by injection molding. In the illustrated embodiment, the positioning of the feet 108a-d and the orientation of the ribs 112 and the windows 118 can enable the injection molding of the adapter 100 with a simple reciprocating mold that requires no “side-action” mechanism.

(14) As can be seen in FIG. 7, the windows 118 serve as receptacles for hose clamps 120 or other fastening devices, such as other radial clamping devices like straps, cable ties, and twist ties, clips and the like. The two hose clamps 120 shown in FIG. 7 are routed through respective windows 118 and around a mounting structure, such as a post 122 of an antenna mount, a monopole, or the like. The feet 108a-d contact the surface of the mounting structure 122 to provide a more stable foundation for the adapter 100. Once mounted on the mounting structure, the adapter 100 is positioned to serve as a mounting point (via the central hole 110) for a cable hanger, such as that shown in FIG. 2. Adapters 100 formed of a polymeric material can be used to mount a metallic cable hanger without creating a potential site of undesirable PIM. Of course, those skilled in this art will appreciate that the polymeric cables hangers, such as those described in U.S. Pat. No. 10,253,906, issued Apr. 9, 2019 (incorporated by reference in full herein), may also be employed.

(15) As shown in FIG. 8, multiple adapters 100 can be mounted at the same elevation with a single hose clamp 120 (or pair of hose clamps 120). Each of the hose clamps 120 is simply routed through one of the windows 118 of each adapter 100 and secured around the mounting structure 122. The trapezoidal profile of the adapter 100 can help to increase of maximize the number of adapters 100 placed side-by-side around the mounting structure 100.

(16) It will also be appreciated that the adapter 100 may be configured such that the side walls 106 may include holes for mounting a cable hanger. Further, in some embodiments, the “open” sides of the adapter 100 may be at least partially closed with side walls, which side walls may include holes for mounting additional cable hangers.

(17) The foregoing is illustrative of the present invention and is not to be construed as limiting thereof. Although exemplary embodiments of this invention have been described, those skilled in the art will readily appreciate that many modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention as defined in the claims. The invention is defined by the following claims, with equivalents of the claims to be included therein.
