- In one embodiment, as shown in
FIGS. 1-7 , agrommet 10 comprises ahousing 100, aback cover 200, a wire-egress cover 300 and atrim ring 400. However, it is also contemplated thatgrommet 10, in another embodiment, may comprise only ahousing 100 and aback cover 200. Still in other embodiments,grommet 10 may further optionally comprise a wire-egress cover 300 or atrim ring 400. - As shown in
FIGS. 1 and 2 ,housing 100 defines aninterior space 120 that is adapted to hold either the female connector 510 (also referred to a “female end”) or male connector 520 (also referred to as a “male end”) of apower cord 500.Housing 100 may comprise atubular wall 130 having a substantially tubular shape that defines afront opening 140 and aback opening 142.Tubular wall 130 extends between thefront opening 140 and back opening 142 ofhousing 100. Also, a wire-egress opening 144 may be provided intubular wall 130 ofhousing 100 so that theinterior space 120 ofhousing 100 communicates with a space outside ofhousing 100, other than through the front andback openings relief cut 148 may be provided adjacent to back opening 142 for accommodating apower cord 500. As shown in the embodiment illustrated inFIGS. 1 and 2 ,housing 100 may have an irregular tubular shape. For example, the shape of a cross-section transverse to a longitudinal axis Z may be asymmetric about a horizontal axis X and/or a vertical axis Y. Further, the cross-sections transverse to the longitudinal axis Z may be non-uniform, i.e., the shape of the cross-sections transverse to the longitudinal axis Z may vary along the longitudinal axis Z. - Additionally, as shown in
FIG. 3 ,housing 100 may comprise aninterior wall 150.Interior wall 150 is disposed insidehousing 100 and extends fromtubular wall 130 acrossinterior space 120 ofhousing 100 to create a separation in theinterior space 120 ofhousing 100.Interior wall 150 defines a frontinterior space 122 and a backinterior space 124 insidehousing 100. Afirst portion 152 ofinterior wall 150 preferably extends substantially vertically from the interior oftubular wall 130 and intointerior space 120 ofhousing 100. Thefirst portion 152 ofinterior wall 150 includes an electrical-connector opening 146 that connects the frontinterior space 122 and the backinterior space 124 ofhousing 100. The backinterior space 124 ofhousing 100 is adapted to receive theelectrical connector power cord 500, such that theelectrical connector interior wall 150 and the female receptacle or male prongs ofelectrical connector connector opening 146. Thefront opening 140 and the frontinterior space 122 are adapted to provide access to theelectrical connector power cord 500, which is disposed in the backinterior space 124 ofhousing 100, so that the mating connector end of another power cord can be connected to theelectrical connector interior space 124 ofhousing 100. Thus,grommet 10 can be mounted flush on a surface and theelectrical connector power cord 500 may be recessed from the surface. - Further, as shown in
FIG. 3 , asecond portion 154 ofinterior wall 150 extends from the interior of thetubular wall 130 at the back edge of the wire-egress opening 144 and slopes/curves up and forward toward frontinterior space 122 andfront opening 140. This particular configuration of thesecond portion 154 ofinterior wall 150 guides any wires or cables that are inserted through wire-egress opening 144 toward frontinterior space 122 andfront opening 140. Thus, whengrommet 10 is installed in a wall, wires or cables (e.g., low voltage audio/video cables) can be easily fed from the interior space of a wall out through the wire-egress opening 144 ofhousing 100. Further, screw posts 156 may disposed on the backside of thesecond portion 154 ofinterior wall 150, in the backinterior space 124 ofhousing 100, for engagingfasteners 158, which secureback cover 200 tohousing 100. - Also, as shown in
FIGS. 1 and 2 ,housing 100 may comprise anannular flange 160 that extends outwardly from thefront opening 140 ofhousing 100 and defines a substantially planar surface transverse to the longitudinal axis Z ofhousing 100.Annular flange 160 comprises afront surface 162 and aback surface 164. When thehousing 100 ofhousing 100 is inserted through an appropriately sized hole in the surface of a wall, theback surface 164 offlange 160 abuts the surface of the wall and preventshousing 100 from falling through the hole. Extending from thefront surface 162 through to theback surface 164 offlange 160 are at least twoholes 166 adapted to receive and engage fasteners 170 (e.g. screws, nails, etc.) for securinghousing 100 to a wall surface. Thus, oncehousing 100 is inserted through a hole in the surface of a wall,fasteners 170 can be inserted throughholes 166 offlange 160 to securehousing 100 to the wall. - Additionally, as shown in
FIGS. 1 and 2 , in one embodiment, toggles 172 may be provided in conjunction withfasteners 170 to securehousing 100 on the surface of a wall.Toggles 172 comprise bores 174 that are adapted to engagefasteners 170.Toggles 172 may be disposed adjacent to theholes 166 on theback surface 164 offlange 160, such that thebores 174 oftoggles 172 are aligned with theholes 166 on theback surface 164 offlange 160. As shown in the embodiment ofFIGS. 1 and 2 , toggles 172 may be held inmounts 132 provided on an outer surface ofhousing 100.Toggles 172 and mounts 132 are preferably configured to allowtoggles 172 to pivot about a longitudinal axis ofbores 174 parallel to longitudinal axis Z. The configuration oftoggles 172 and mounts 132 allowtoggles 172 to rotate between a closed position (as shown inFIGS. 4 and 6 ) and an open position (as shown inFIGS. 1 and 2 ) when afastener 170 is rotated in a tightening direction (e.g., clockwise). Likewise, when afastener 170 is rotated in a loosening direction (e.g., counter clockwise), toggles 172 may rotate from an open position to a closed position. Preferably, mounts 132 includedetents 134 that prevent toggles 172 from moving in an opening direction past a certain point, such that toggles 172 are substantially radially aligned with longitudinal axis Z ofhousing 100. Ashousing 100 is inserted through a hole in the surface of a wall, toggles 172 may be held in a closed position. Oncehousing 100 has been inserted through a hole in the surface of a wall andfasteners 170 are tightened, toggles 172 may move into an open position and engage the backside of the wall to securehousing 100 to the wall. - As shown in
FIGS. 5 and 7 ,grommet 10 further comprisesback cover 200 that is adapted to engagehousing 100 ofhousing 100 at theback opening 142. Back cover 200 comprises at least twoholes 202 for receivingfasteners 158. Theholes 202 are configured to align with the screw posts 156 so thatfasteners 158 may be inserted throughholes 202 inback cover 200 and engage screw posts 156. Once theelectrical connector power cord 500 is inserted into backinterior space 124 ofhousing 100,electrical connector housing 100 by attaching backcover 200 tohousing 100 and insertingfasteners 158 throughholes 202 and into screw posts 156. Thus, by enclosing the backinterior space 124 ofhousing 100 withback cover 200, anelectrical connector interior space 124 such that the female receptacle or male prongs ofelectrical connector front opening 140 and front interior space through the electrical-connector opening 146. - Also, as shown in

Wire-egress cover 300 preferably includes aplanar surface 310 that is shaped to match the shape of a portion of a cross section of theinterior space 120 ofhousing 100 such that the interior space—between thesecond portion 154 ofinterior wall 150 and the interior oftubular wall 130—that leads to wire-egress opening 144 can be covered while still allowing wires or cables to be passed through an opening 344 in theplanar surface 310 of the wire-egress cover 300. Wire egress cover may further includearms 320 that extend orthogonally fromsurface 310.Arms 320 are adapted to fit in the frontinterior space 122 ofhousing 100 and engage the interior surface oftubular wall 130 so that wire-egress cover 300 may be secured tohousing 100. Wire-egress cover 300 may also includetabs 330 disposed on the free ends ofarms 320.Tabs 330 are configured to engagerecesses 136 in the interior surface oftubular wall 130. Wire-egress cover 300 may further include an opening 344 to allow wires or cables to be passed through the wire-egress opening 144 when theegress cover 300 is installed. - Additionally, as shown in
FIGS. 5 and 7 ,grommet 10 may further optionally comprise atrim ring 400.Trim ring 400 includes a substantiallyplanar surface 410 that defines acentral opening 420 for allowing access to theinterior space 120 ofhousing 100. Extending orthogonally fromsurface 410 is asemi-cylindrical wall 430.Semi-cylindrical wall 430 partially encirclescentral opening 420 onsurface 410 and is adapted to extend inwardly intointerior space 120 ofhousing 100.Semi-cylindrical wall 430 is adapted to engage the interior surface oftubular wall 130 so thattrim ring 400 may be secured tohousing 100.Trim ring 400 is preferably adapted to securely fit on theflange 160 ofhousing 100 without the need for fasteners (e.g., snap-fit connection).Trim ring 400 is configured to coverfasteners 170 onflange 160 and provide an even finished surface around thefront opening 140 ofhousing 100. Thus,trim ring 400 provides a clean finished appearance to the portion ofgrommet 10 that is visible after installation in a wall. - In another embodiment, as shown in
FIGS. 8 and 9 , agrommet 80 comprises ahousing 800 and atrim ring 810. Thehousing 800 may comprise atubular wall 830 having a substantially tubular shape that defines aninterior space 820, afront opening 840 and aback wall 842.Tubular wall 830 extends between thefront opening 840 andback wall 842 ofhousing 800. Theback wall 842 of thehousing 800 defines anopening 844 so that theinterior space 820 ofhousing 800 communicates with a space outside ofhousing 800. Thus, whengrommet 80 is installed in a wall, wires or cables (e.g., low voltage audio/video cables) can be easily fed through theopening 844 ofhousing 800 into the interior space of a wall. Further, as shown in the embodiment illustrated inFIGS. 8 and 9 ,housing 800 may have an irregular tubular shape.
