Description
TECHNICAL FIELD
[0001] This invention relates to a rotating power grommet to supply
electric lines and data lines into a work surface, such as a
conference table, boardroom table or office desk.
BACKGROUND
[0002] There are devices for supplying electric power and data
devices into work surfaces, desks, counters, conference tables,
boardroom tables, and any other surfaces where power, data, are
needed. Present solutions to this problem generally involve a metal
box, with or without a lid, making it difficult for a designer to
integrate it into furniture. Designers have solved this problem by
recessing the box beneath a table but this creates a problem of how
to open the door, and how to avoid damaging the adjacent surface of
the table while doing so.
[0003] Other designers offer interfaces that raise and lower a
power and data device, which have a number of power receptacles,
with or without data terminals. These devices have each of the
receptacles and terminals lined up in a row on one side or on
opposite sides in a fixed position. An example is shown in U.S.
Pat. No. 4,747,788. Depending on the power grommet's orientation
the receptacles might not be easily accessible or one of the free
outlets might be blocked by a larger plug. Turning the outlets to
any direction offers a new level access and personalization of
cords.
SUMMARY
[0004] The power and data grommet of this invention comprises a
grommet adapted to be placed in an aperture in the desk or other
work surface. An aperture is manufactured or drilled through the
top of the work surface. A housing; which is adapted to fit into
the aperture, comprises, a plurality of power receptacles, each of
which is rotatable 360.degree., so that it is easy for a person to
plug into a receptacle facing the person, at any part of the table.
The grommet of this invention may, or may not, lower into the table
and raise up when in use.

DETAILED DESCRIPTION
[0018] As required, detailed embodiments of the present invention
are disclosed herein; however, it is to be understood that the
disclosed embodiments are merely exemplary of the invention that
may be embodied in various and alternative forms. The figures are
not necessarily to scale; some features may be exaggerated or
minimized to show details of particular components. Therefore,
specific structural and functional details disclosed herein are not
to be interpreted as limiting, but merely as a representative basis
for teaching one skilled in the art to variously employ the present
invention.
[0019] Referring now to the drawings, there is shown in FIG. 1 a
perspective view of the circular grommet 10 of the present
invention. There are three sections of the grommet 12, 14, and 16.
Section 12 has an electrical plug 18, section 14 also has an
electrical plug 20 and section 16 has a data plug 22. The grommet
could have a plurality of modules each having an electrical plug or
a data port. The grommet modules could have all electrical plugs or
all data plugs, depending upon need. The drawings shown in this
application generally show three modules, strictly for ease of
description, but the grommet could have less or more electrical
plugs, up to even 5 or more modules or combination of electrical
plugs and data plugs.
[0020] A liner 24 fits into a hole 28 in the desk top where grommet
10 is installed. A base portion 26 of the grommet fits down below
the surface of the desk top 34 (see FIG. 2).
[0021] Referring to FIG. 2, there is shown a similar grommet 30
fitting into a hole 32 in the desk top 34. The grommet has three
electrical plugs 36, 38 and 40. A liner 42 fits into hole 32. The
liner has a lip 44 which lays on the top of the desk top 34. Lip 44
has a greater diameter than hole 32 so that the grommet does not
fall through hole 32. This grommet 30 also has a top 46 which has
an optional light connected under top 46. Plug 38 is shown rotated
90.degree.. Each of the plugs 36, 38 and 40 can be rotated
360.degree. to any desired location.
[0022] FIG. 3 shows the internal structure of the rotating power
grommet. There are three stamped vertical copper strips 50, 51 and
52 for the positive, negative and ground. These strips are soldered
to wires 54, 56 and 58 which continue through a base 60 below to
reach an outside electrical power source. Referring to FIG. 4,
there is shown the copper strips mounted in a vertical plastic
shaft 62. Only copper strip 51 is visible. Wires 54, 56 and 58
continue into base 60,
[0023] Shaft 62 mounts into base 64 as shown in FIG. 5. Each copper
strip 50, 51 and 52 has a plurality of small folds 53, 55 and 57
(as examples) that extend outward from their recess to make contact
with horizontal rings (shown in FIGS. 6 and 7) to transfer
electrical power to the plugs. The horizontal rings are contained
in a two part clamp to facilitate assembly and stacking of multiple
receptacles.
[0024] Referring to FIG. 6, there is shown an electrical receptacle
66 of the rotating power grommet. Receptacle 66 has two parts, 68
and 70. Part 70 has two arms 72 and 74 which are adapted to swing
into openings 76 and 78 in part 68. Openings 76 and 78 are spaced
between arms 80 and 82 and arms 84 and 86. When arm 74 fits between
arm 84 and 86, a connector, such as a screw 88, fits into holes in
the arms 84, 86 and 74 to hold the two parts 68 and 70 together.
The holes in arms 84, 86 and 74 are not visible but holes 90 and 92
and 94 show how they will also swing into place and can be
tightened by a connector, such as a screw 89.
[0025] When closed, the two parts 68 and 70 form a central hole,
created by semi-holes 96, 98. Inner surfaces of semi holes 96 and
98 are molded with copper strips 100, 102 and 104 in part 68 and
106, 108 and 110 in part 70. Vertical shaft 62 is clamped into the
central hole discussed above. This transfers electrical power from
vertical shaft 62 to the horizontal copper strips 100-110 and
allows for a 360.degree. rotation of the plugs.
[0026] Referring now to FIG. 7, there is shown the placement of
plug 66, with face 67 into a plastic housing 112. Plastic housing
112 has a smaller diameter section 113. When another plastic
housing (not shown) is placed above plastic housing 112, the bottom
diameter sits on top of the ridge formed by smaller diameter 113.
This can be continued upward as each plug is placed into another
plastic housing. Dotted lines are used to show that the dotted
parts are inside of the grommet outer shell. Electrical receptacle
114, with face 115, is fixed above receptacle 66. Each receptacle
can rotate 360.degree. separate from each other receptacle. As
described in FIG. 6, receptacle 114 is molded with copper strips
and vertical shaft 62 is clamped into the central hole.
[0027] Plug pins 116, 118 and 120 are three female pins which sit
inside of receptacle 114. Pins 122, 124 and 126, sitting above
receptacle 114, show the connection between the pins 122, 124 and
126, each having a copper strap 128, 130 and 132, tightened around
shaft 62, to transfer the vertical power of shaft 62 to the copper
straps 128, 130 and 132. The receptacle is not shown in order to
show the manner in which the pins are connected. Each of the three
receptacles 66, 114 and a receptacle not shown, which will use pins
122, 124 and 126, to form another receptacle, are separately
rotatable 360.degree..
[0028] Referring now to FIG. 8, there is shown a portion of shaft
62 with vertical copper strips 50 and 52. As shown previously,
copper strip 50 has a plurality of small folds, 53 is shown, and
copper strip 52 has a small fold 55 shown. These folds 53 and 55
(as examples) extend out from their recess to make contact with
horizontal rings (shown in FIGS. 6 and 7) to transfer the power to
the plugs. Copper strap 130 is tightened around shaft 62 and
contacts small fold 55 to transfer electrical power to pin 124,
which receives a male plug pin (three plug pins are usually used)
to supply electric power to whatever device is plugged in.
[0029] Referring to FIG. 9, there is shown the typical plug
assembly 66, with face 67, shown in FIGS. 6 and 7. The plug
assembly 66 is snapped into the receptacle opening of a plastic
housing 140. Part 68 and 70 are ready to be closed around shaft 62.
Copper strips 100, 102 and 104 will take horizontal power transfer
of the vertical power (shaft 62). Arm 72 will rotate under arm 82
and when fully rotated in, a screw will pass through holes 90 and
94, similar to screw 88 to close receptacle 66.
[0030] In FIG. 10, housing 140, with face 67, is then dropped over
shaft 62 which has copper strip 51 with fold 57. Parts 68 and 70
are ready to be closed over shaft 62, and a screw inserted, similar
to screw 88.
[0031] Referring to FIG. 11, the receptacle 66, with face 67, is
clamped and parts 68 and 70 closed by screws 88 and 142 to complete
the electrical connection from the vertical shaft 62, with copper
strip 51 with fold 57, to the horizontal receptacle.
[0032] Referring to FIG. 12, There is shown a completed rotating
grommet in which each of the rings 201, 202 and 203 with
receptacles 204, 205 and 206, will each rotate a full 360.degree.,
and anywhere in between, so that a person using the grommet who is
sitting facing the back side of the receptacles could simply rotate
one ring so that the receptacle faced them and they can easily plug
their device into that grommet receptacle. The grommet fits into a
base 208 and the grommet has an optional cap 210.
[0033] Referring to FIG. 13, shows the same grommet of FIG. 12 but
with a longer view of the base 208, and showing rim 209 which stops
the grommet from falling through the hole in the desk surface.
There is also a top cap 212 and an optional light 211, such as an
LED light for kitchen applications, using a power switch and a
rubber seal for liquid if needed.
[0034] Optionally, existing power receptacles may be used with the
vertical shaft and clamp. The grommet can be mounted in three
different ways. One is mounted to a surface and it pops up through
the grommet hole. This can be done by pressing the top down and the
unit raises up an inch or so. Then you lift the unit up and it
locks in place or the unit can be spring loaded to raise up.
Another option is that the unit is mounted in a fixed, upright
position. Yet another option could be mounted under a desk or wall
mounted that could consist of up to six outlets.
[0035] While exemplary embodiments are described above, it is not
intended that these embodiments describe all possible forms of the
invention. Rather, the words used in the specification are words of
description rather than limitation, and it is understood that
various changes may be made without departing from the spirit and
scope of the invention. Additionally, the features of various
implementing embodiments may be combined to form further
embodiments of the invention.
