DESK WITH HIDDEN WIRING
Abstract
A desk provided with a vertical flat pedestal supporting one end
of the top has a wiring channel formed in an edge of the pedestal.
A nose molding closes the channel normally, but may be removed to
lay in an appliance cord without disconnecting the cord from either
the appliance or its connector plug. Notches are provided at the
top and bottom of the channel in which the cord may be laid for
ingress and egress when the nose cap is replaced.

Claims
We claim:
1. In a desk or the like having a top, a supporting pedestal at the
end of the top and extending to the upper surface of the top, a
vertical channel means in the pedestal, removable cover means for
the channel, and means forming a pair of notches, one adjacent each
end of the channel whereby an appliance cord may be laid in the
channel means and the cover closed to leave the cord extending into
and out of the channel through the notches.
2. A desk as defined in claim 1 wherein the pedestal comprises
spaced inner and outer panels and the channel means is formed by
the vertical ends of the spaced panels.
3. A desk as defined in claim 1 wherein the cover means comprises a
block member applied to the end of the table top adjacent the
pedestal and a shaped nose molding removably secured to a vertical
edge of the pedestal.
4. A desk as defined in claim 3 wherein a cap member is secured to
the top of the pedestal and abuts the block member at their top
surfaces and a removable knockout is provided in one of said
members to normally close the notch at the top end of the
channel.
5. A desk as defined in claim 1 wherein the pedestal comprises a
peripheral inner frame, a pair of opposed panels covering the frame
on the inside and outside end faces and projecting beyond the frame
at one vertical edge of the pedestal, the panels having reentrant
inwardly facing flanges lying adjacent the frame at the
channel-forming edges thereof, and a U-shaped spring clip screwed
to the frame and overlapping the panel flanges to hold them in
position against the frame, the clip also having yielding ends
engaging and holding the cover means for the channel.
6. A desk as defined in claim 5 wherein the lower one of said
notches is located in the projecting edge of one of the panels.
Description
Many of the appliances used in modern offices require electric
power, are positioned upon desk tops, and require a power cord
leading from an outlet receptacle frequency mounted in the floor or
the nearby baseboard of the building. Efforts have been made to
position these cords internally of the desk structure for both
appearance and safety reasons. To thread a cord through the
passageways previously provided requires that the cord be
disconnected from the appliance or from the connector plug at the
opposite end in order to thread it through a hole of reasonable
size for the cord.
An object of the present invention is to provide a desk having
wiring channels selectively usable at various points in the desk
and which do not require threading of an appliance cord
therethrough, but in which the entire channel may be laid open and
the cord laid in with the plug and appliance attached.
A further object is to provide wiring channel means of the
character described in which the appliance cord may be presented at
the top surface of the desk at any one of a plurality of locations
and in which any unused channel is closed at the desk top and may
be opened when needed by removing a simple knockout.
These objects are accomplished by the present invention which
consists in a desk or the like having a top, a supporting pedestal
at the end of the top and extending to the upper surface of the
top, means forming a vertical channel means in the pedestal,
removable cover means for the channel, means forming a pair of
notches, one adjacent each end of the channel whereby an appliance
cord may be laid in the channel and the cover closed to leave the
cord extending into and out of the channel through the notches.
IN THE DRAWINGS
FIG. 1 is a perspective view of a desk or table incorporating a
preferred form of the present invention.
FIG. 2 is a fragmentary view of an end portion of the table of FIG.
1.
FIG. 3 is a fragmentary sectional view on line 3--3 of FIG. 1.
FIG. 4 is a fragmentary perspective view of the bottom portion of
the table.
FIG. 5 is a fragmentary sectional view on line 5--5 of FIG. 2.
The desk of FIG. 1 comprises a top 10 supported by end pedestals 12
which are secured in abutting relation to the ends of the top 10.
The pedestals 12 are preferably formed of a ladderlike inner frame
formed of rectangular metal tubing as indicated at 14 in FIG. 3.
Inner and outer face panels 16 are secured to the frame 14 by means
of spring clips 18 which engage the reentrant flanges 20 of the
face panels 16. These panels are so shaped at their vertical edges
that they provide a channel between them to receive an appliance
cord as illustrated in FIG. 1. The inner face panel is provided
with a notch 22 in which the appliance cord 24 may be laid for
entrance to the wiring channel.
Cover means for the wiring channel comprises a nose molding 25 and
a block member 26. The molding 25 is snapped onto the spring clips
18 and the block 26 is secured to the end of the table top 10 by a
bolt 28. The block 26 is provided with a semicircular notch 29
overlying the top of the wiring channel and flush with the upper
surface of the table top 10. The top end of the pedestal is closed
by a molded cap member 30 which, when first installed, has circular
knockouts 32 filling each of the notches 29. When one of these
knockouts is removed, there is thus provided a circular opening
which includes the notch 29 and through which the appliance cord 24
may extend to the top surface of the desk. Preferably, the four
vertical edges of the two pedestals 12 are constructed in identical
fashion so that there will be four knockouts 32, any one or more of
which may be utilized to provide cord egress from the channel over
which it lies.
To install or remove an appliance cord in one of the channels, it
is merely necessary to remove the block 26 by loosening the bolt 28
and to snap the cover molding 25 off from the clips 18. The cord is
then laid into (or removed) the channel and the molding 25 and the
block 26 replaced. If the cord is being installed for the first
time, the knockout 32 at the top of the channel being utilized is,
of course, removed. If use of the channel is being discontinued,
the open hole may be closed by a suitable snap-in plug, not
illustrated.
