DETAILED DESCRIPTION
[0017] Before the present invention is described in further detail,
it is to be understood that the invention is not limited to the
particular embodiments described. It is also to be understood that
the terminology used herein is for the purpose of describing
particular embodiments only, and is not intended to limit the scope
of the claims of the present application.
[0018] In accordance with one aspect of the invention, provided is
a wall grommet 10, which can be installed through the surface of a
wall to route wiring in the wall's interior space. Grommet 10 can
be used to route power cords and low-voltage cables for audio and
video applications.
[0019] In one embodiment, grommet 10 comprises a power module 100,
a back cover 200, a wire egress cover 300 and a trim ring 400.
However, it is also contemplated that grommet 10, in another
embodiment, may comprise only a power module 100 and a back cover
200. Still in other embodiments, grommet 10 may further optionally
comprise a wire egress cover 300 or a trim ring 400.
[0020] As shown in FIGS. 1 and 2, power module 100 comprises a
housing 110, which defines an interior 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 a
power cord 500. Housing 110 may comprise a tubular wall 130 having
a substantially tubular shape that defines a front opening 140 and
a back opening 142. Tubular wall 130 extends between the front
opening 140 and back opening 142 of housing 110. Also, a
wire-egress opening 144 may be provided in tubular wall 130 of
housing 110 so that the interior space 120 of housing 110
communicates with a space outside of housing 110, other than
through the front and back openings 140, 142. Further, a relief cut
148 may be provided adjacent to back opening 142 for accommodating
a power cord 500. As shown in the embodiment illustrated in FIGS. 1
and 2, housing 110 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.
[0021] Additionally, as shown in FIG. 3, housing 110 may comprise
an interior wall 150. Interior wall 150 is disposed inside housing
110 and extends from tubular wall 130 across interior space 120 of
housing 110 to create a separation in the interior space 120 of
housing 110. Interior wall 150 defines a front interior space 122
and a back interior space 124 inside housing 110. A first portion
152 of interior wall 150 preferably extends substantially
vertically from the interior of tubular wall 130 and into interior
space 120 of housing 110. The first portion 152 of interior wall
150 includes an electrical-connector opening 146 that connects the
front interior space 122 and the back interior space 124 of housing
110. The back interior space 124 of housing 110 is adapted to
receive the electrical connector 510, 520 of a power cord 500, such
that the electrical connector 510, 520 abuts interior wall 150 and
the female receptacle or male prongs of electrical connector 510,
520 are accessible through the electrical-connector opening
146.
[0022] As shown in FIGS. 5 and 7, the electrical connector 510, 520
may have a body comprising a flange 512, 522 configured to engage
the interior wall 150 of the housing 110 around the
electrical-connector opening 146. Further, the body of the
electrical connector 510, 520 may further comprise a front face
514, 524 that is configured to be disposed substantially vertically
when the electrical connector 510, 520 is disposed inside the
housing 110 and the grommet 10 is mounted on a surface of a
vertical wall. The body of the electrical connector 510, 520
extends back from the front face 514, 524 generally perpendicularly
to the plane of the front face 514, 524. As shown in FIGS. 5 and 7,
the power chord 500 of the electrical connector 510, 520 may extend
transversely to the body of the electrical connector 510, 520 so
that the power chord 500 can be routed vertically inside the wall.
The front face 514, 524 of the electrical connector 510, 520, which
has the female receptacle or male prongs disposed thereon, may be
configured to protrude from the flange 512, 522 such that the front
face of the electrical connector 510, 520 extends through the
electrical-connector opening 146 when the flange 512, 522 engages
the interior wall 150 of the housing 110 around the
electrical-connector opening 146.
[0023] The front opening 140 and the front interior space 122 are
adapted to provide access to the electrical connector 510, 520 of
power cord 500, which is disposed in the back interior space 124 of
housing 110, so that the mating connector end of another power cord
can be connected to the electrical connector 510, 520 disposed in
the back interior space 124 of housing 110. Thus, grommet 10 can be
mounted flush on a surface and the electrical connector 510, 520 of
power cord 500 may be recessed from the surface. As shown in FIGS.
5-8, grommet 10 is configured such that when grommet 10 is mounted
flush on the surface of a vertical wall, the front face 514, 524 of
the electrical connector 510, 520 is disposed substantially
vertically and parallel to the surface of the vertical wall, and
the power cord 500 extends substantially transversely to the
longitudinal axis Z of housing 110 and substantially vertically
inside the wall.
[0024] Further, as shown in FIG. 3, a second portion 154 of
interior wall 150 extends from the interior of the tubular wall 130
at the back edge of the wire-egress opening 144 and slopes/curves
up and forward toward front interior space 122 and front opening
140. This particular configuration of the second portion 154 of
interior wall 150 guides any wires or cables that are inserted
through wire-egress opening 144 toward front interior space 122 and
front opening 140. Thus, when grommet 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 trough the
wire-egress opening 144 of power module 100. Further, screw posts
156 may disposed on the backside of the second portion 154 of
interior wall 150, in the back interior space 124 of housing 110,
for engaging fasteners 158, which secure back cover 200 to power
module 100.
[0025] Also, as shown in FIGS. 1 and 2, power module 100 may
comprise an annular flange 160 that extends outwardly from the
front opening 140 of housing 110 and defines a substantially planar
surface transverse to the longitudinal axis Z of housing 110.
Annular flange 160 comprises a front surface 162 and a back surface
164. When the housing 110 of power module 100 is inserted through
an appropriately sized hole in the surface of a wall, the back
surface 164 of flange 160 abuts the surface of the wall and
prevents power module 100 from falling through the hole. Extending
from the front surface 162 through to the back surface 164 of
flange 160 are at least two holes 166 adapted to receive and engage
fasteners 170 (e.g. screws, nails, etc.) for securing power module
100 to a wall surface. Thus, once power module 100 is inserted
through a hole in the surface of a wall, fasteners 170 can be
inserted through holes 166 of flange 160 to secure power module 100
to the wall.
[0026] Additionally, as shown in FIGS. 1 and 2, in one embodiment,
toggles 172 may be provided in conjunction with fasteners 170 to
secure module 100 on the surface of a wall. Toggles 172 comprise
bores 174 that are adapted to engage fasteners 170. Toggles 172 may
be disposed adjacent to the holes 166 on the back surface 164 of
flange 160, such that the bores 174 of toggles 172 are aligned with
the holes 166 on the back surface 164 of flange 160. As shown in
the embodiment of FIGS. 1 and 2, toggles 172 may be held in mounts
132 provided on an outer surface of housing 110. Toggles 172 and
mounts 132 are preferably configured to allow toggles 172 to pivot
about a longitudinal axis of bores 174 parallel to longitudinal
axis Z. The configuration of toggles 172 and mounts 132 allow
toggles 172 to rotate between a closed position (as shown in FIGS.
4 and 6) to an open position (as shown in FIGS. 1 and 2) when a
fastener 170 is rotated in a tightening direction (e.g.,
clockwise). Likewise, when a fastener 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 include
detents 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 of power
module 100. As power module 100 is inserted through a hole in the
surface of a wall, toggles 172 may be held in a closed position.
Once power module 100 has been inserted through a hole in the
surface of a wall and fasteners 170 are tightened, toggles 172 may
move into an open position and engage the backside of the wall to
secure power module 100 to the wall.
[0027] As shown in FIGS. 5 and 7, grommet 10 further comprises back
cover 200 that is adapted to engage housing 110 of power module 100
at the back opening 142. Back cover 200 comprises at least two
holes 202 for receiving fasteners 158. The holes 202 are configured
to align with the screw posts 156 so that fasteners 158 may be
inserted through holes 202 in back cover 200 and engage screw posts
156. Once the electrical connector 510, 520 of power cord 500 is
inserted into back interior space 124 of housing 110, electrical
connector 510, 520 can be secured in housing 110 by attaching back
cover 200 to power module 100 and inserting fasteners 158 through
holes 202 and into screw posts 156. Thus, by enclosing the back
interior space 124 of housing 110 with back cover 200, an
electrical connector 510, 520 can held and secured in the back
interior space 124 such that the female receptacle or male prongs
of electrical connector 510, 520 can be accessed from the front
opening 140 and front interior space through the
electrical-connector opening 146.
[0028] Also, as shown in FIGS. 5 and 7, Grommet 10 may further
optionally comprise a wire egress cover 300. Wire egress cover 300
preferably includes a planar surface 310 that is shaped to match
the shape of a portion of a cross section of the interior space 120
of power module 100 such that the interior space--between the
second portion 154 of interior wall 150 and the interior of tubular
wall 130--that leads to wire-egress opening 144 can be covered
while still allowing wires or cables to be passed through. Wire
egress cover may further include arms 320 that extend orthogonally
from surface 310. Arms 320 are adapted to fit in the front interior
space 122 of housing 110 and engage the interior surface of tubular
wall 130 so that wire egress cover 300 may be secured to power
module 100. Wire egress cover 300 may also include tabs 330
disposed on the free ends of arms 320. Tabs 330 are configured to
engage recesses 136 in the interior surface of tubular wall 130.
Wire egress cover 300 may further include a notch 340 cut out to
allow wires or cables to be passed through the wire-egress opening
144 when the egress cover 300 is installed.
[0029] Additionally, as shown in FIGS. 5 and 7, grommet 10 may
further optionally comprise a trim ring 400. Trim ring 400 includes
a substantially planar surface 410 that defines a central opening
420 for allowing access to the interior space 120 of power module
100. Extending orthogonally from surface 410 is a semi-cylindrical
wall 430. Semi-cylindrical wall 430 partially encircles central
opening 420 on surface 410 and is adapted to extend inwardly into
interior space 120 of housing 110. Semi-cylindrical wall 430 is
adapted to engage the interior surface of tubular wall 130 so that
trim ring 400 may be secured to power module 100. Trim ring 400 is
preferably adapted to securely fit on the flange 160 of power
module 100 without the need for fasteners. Trim ring 400 is
configured to cover fasteners 170 on flange 160 and provide an even
finished surface around the front opening 140 of power module 100.
Thus, trim ring 400 provides a clean finished appearance to the
portion of grommet 10 that is visible after installation in a
wall.
[0030] In accordance with another aspect of the invention, as shown
in FIG. 8, provided is a wall grommet assembly 600. Wall grommet
assembly 600 may comprise two wall grommets 10', 10'' (as described
above) and a power cord 500. Power cord 500 preferably has a female
connector 510 on one end and a male connector 520 on the other end.
Further, power cord 500 preferably comprises type NM-B cable, or
other type of cable that is rated for use inside walls. As shown in
FIGS. 4 and 5, grommet 10' is used in conjunction with the female
connector 510 of power cord 500, as shown in FIGS. 4 and 5. As
shown in FIGS. 6 and 7, grommet 10'' is used in conjunction with
the male connector 520 of power cord 500, as shown in FIGS. 6 and
7. As shown in FIG. 8, wall grommet assembly 600 may be installed
by cutting out two holes on the surface of a wall and running power
cord 500 inside the wall such that female connector 510 comes out
of the wall through one hole and male connector 520 comes out of
the wall through the other hole. Then, female connector 510 can be
secured in grommet 10' and male connector 520 can be secured in the
other grommet 10''. Grommets 10', 10'' can then be inserted through
their respective holes in the wall and secured to the surface of
the wall using fasteners (e.g. screws, nails, etc.) through holes
166 in flange 160. Additionally, other cables (e.g., low-voltage
audio/video cables) may be passed through the wire-egress opening
144 of one grommet 10', through the interior space of the wall, and
out through the wire-egress opening 144 of the other grommet 10''.
Wire egress covers 300 and/or trim rings 400 may also be secured on
the power modules 100', 100'', as desired.
[0031] In accordance with yet another aspect of the invention, as
shown in FIG. 9, provided is a kit 700 for routing wiring in the
interior spaces of walls. In one embodiment the kit 700 comprises a
saw 710, a fish stick 720, two grommets 10', 10'', and a power cord
500. Saw 710 may be any conventional saw that can be used to cutout
holes in the surface of walls (e.g., drywall saw). Fish stick 720
comprises a rod 722 with a hook 724 (or other means for holding a
cable) on one end. The rod 722 may have a one-piece construction,
or it may be provided in multiple sections (as shown) that are
connected by connectors 726. The two grommets 10', 10'' and power
cord 500 may be provided in accordance with the preceding
descriptions.
[0032] Saw 710 may be used to cut out holes on the surface of a
wall. Once two holes are cut out, fish stick 720 may be inserted
through one of the holes and into the wall such that the hook 724
on the end of the rod 710 can be accessed through the other hole.
One end of the power cord 500 can be secured on the hook 724 and
inserted through the hole such that the power cord 500 can be
fished through the inside of the wall by pulling out the other end
of fish stick 720 through the other hole. Power cord 500 may be
fished through the inside of the wall such that one end of the cord
comes out of the wall through one hole and the other end of the
cord comes out of the wall through the other hole. Then, female
connector 510 can be secured in grommet 10' and male connector 520
can be secured in the other grommet 10''. Grommets 10', 10'' can
then be inserted through their respective holes in the wall and
secured to the surface of the wall using fasteners (e.g. screws,
nails, etc.) through holes 166 in flange 160. Additionally, other
cables (e.g., low-voltage audio/video cables) may be passed through
the wire-egress opening 144 of one grommet 10', through the
interior space of the wall, and out through the wire-egress opening
144 of the other grommet 10''. Wire egress covers 300 and/or trim
rings 400 may also be secured on the power modules 100', 100'', as
desired.
[0033] While the invention has been described with reference to the
preferred embodiments thereof, it will be appreciated by those of
ordinary skill in the art that modifications can be made to the
structure and elements of the invention without departing from the
spirit and scope of the invention as a whole.
