Abstract
A furniture leg wire management apparatus is configured for use with a furniture leg formed by opposite leg posts separated by a gap. The apparatus includes a legway defined by an elongated tubular body. The body includes a forward portion and opposite clamping arms that are resiliently deflectable toward each other. The clamping arms are deflected when the legway is pushed into the gap between the leg posts and provide an outwardly directed force to clamp the legway in this operative position. The tubular body further includes a central rib terminated in a rear flange. The central rib divides the legway into two wire/cable channels, while the rear flange cooperates with the clamping arms to define opposite elongated slots. The slots communicate with the two cable channels to provide an avenue to feed the wires/cables into a corresponding channel. The wire management apparatus further includes a decorative cover plate that is removably mounted on the legway to improve its aesthetics.
Description




BACKGROUND OF THE INVENTION




The present invention relates to wire management systems for furniture, particular office furniture, such as conference/training tables or workstations. More specifically, the invention concerns a wire management apparatus incorporated into a leg of the office furniture.




The plethora of electrical equipment used in most office environments presents a nettlesome problem, namely the problem of managing the seemingly endless array of electrical wires and data cables associated with the equipment. For example, a typical workstation personal computer will include power cables for the computer, printer and monitor, data cables between each of these components, networking cables, phone lines, and even wires associated with audio components of more sophisticated work stations. This problem is compounded where multiple workstations are involved, such as in a conference or training facility. Many such facilities utilize a number of large tables having multiple workstations. In these circumstances, the number of wires and cables that must be managed can be daunting.




Many articles of business furniture incorporate bezels formed in the working surface of the furniture through which the wires and cables pass. These bezels help clear the working surface of electrical wiring, but do little to solve the overall wire management problem. Many multiple workstation tables incorporate wire management features that channel the wires and cables through raceways attached to the table. While these raceways go a step further in clearing the working area of loose wires, these components still leave the problem of carrying the wires to wall outlets to power up the workstation electronics. The raceway suffers from the detriment common to the furniture wire bezel in which the wires still dangle from the furniture on their path to the wall outlet. These dangling wires and cables pose a risk that a workstation operator will unwittingly become tangled in the wiring. Moreover, the exposed wiring is generally aesthetically displeasing.




Consequently, there remains a need in the field of wire management for a system to virtually eliminate all dangling and exposed wires and cables. The optimum goal is to provide a system that emulates a fully hidden hard-wired approach in the arena of movable and/or stowable furniture.




SUMMARY OF THE INVENTION




In order to achieve this optimum goal, the present invention contemplates a furniture leg that is an integral component in the wire management protocol. In one aspect of the invention, the table leg includes a pair of leg posts separated by a gap but joined at the bottom of each post to feet configured for supporting the leg on the floor. A tubular legway is resiliently mounted within the gap or channel between the leg posts. The legway defines an entry opening or notch at the upper end of the legway immediately adjacent the underside of the working surface of the article of furniture. An exit opening is formed at the bottom end of the legway adjacent the feet. The tubular legway is sized to house a plurality of electrical wires and data cables with the wires passing through the upper entry notch and out the lower exit opening.




In one feature of the legway, the tubular body includes opposite clamping arms that form arcuate recesses. The clamping arms are joined at a forward portion so that the legs are resiliently deflectable toward each other. In the natural or unstressed configuration of the legway, the clamping arms are splayed apart. The legway can be pressed into the gap or channel between the leg posts by deflecting the clamping arms toward each other. With the legway fully disposed in the gap, the leg posts reside within the recess defined in the clamping arms, and the clamping arms exert an outward restorative force to maintain the legway in that operative position.




In a further aspect of the invention, the tubular body of the legway includes a central rib extending along the length of the legway. The central rib stiffens the elongated legway and divides the legway into two wire channels. The central rib preferably includes a rear flange that cooperates with each of the clamping arms to define wire entry slots extending along the length of the legway. The wire entry slots are sized to allow passage of electrical/data wires and cables into the wire channels. This feature eliminates the need to guide the plug or connector end of the wire/cable through the length of the legway and out the lower exit opening. On the other hand, the wire entry slots are narrow enough to reduce the likelihood that any wire or cable will slide out of the legway.




Yet another feature of the furniture leg wire management apparatus of the present invention is a cover plate mounted on the tubular legway. In the preferred embodiment, the cover plate is decorative, so that the legway itself can be formed of a plain, aesthetically neutral material. The cover plate can be in the form of an elongated arcuate sheet of material with inwardly directed tangs at the free edges of the sheet. The tangs fit into corresponding slots defined in the tubular body of the legway.




It is one object of the invention to provide a further link in the chain of wire management for electrified furniture. One specific object is to provide means to conceal and manage wires and cables that would otherwise hang from the working surface of the furniture.




Another object of the present invention is realized in certain features that allow the wire management apparatus to be readily removed for modification or storage. A further object is to provide a furniture leg-based wire management apparatus that is aesthetically pleasing.




These objects and certain benefits of the invention can be discerned from the following written description and accompanying figures.

DESCRIPTION OF THE PREFERRED EMBODIMENTS




For the purposes of promoting an understanding of the principles of the invention, reference will now be made to one preferred embodiment illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated embodiment, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.




The present invention relates to wire management for “electrified” furniture, or furniture on which an array of electrical equipment is supported. Furniture of this type can include conference or training tables, and the electrical equipment can include a wide array of devices, such as lights, computers, printers, typewriters, etc. An illustration of the problem is found in

FIG. 1. A

worktable T is supported by a leg assembly L, which in the illustrated embodiment is attached by a folding mechanism F. The table T provides a working surface for a personal computer C, a monitor M, as well as other electrical devices not depicted. The devices include a plurality of wires W that must be plugged into wall socket(s). With this conventional table arrangement, the wires W dangle precariously from the table T and are thus susceptible to becoming entangled by the work table user. Moreover, the hanging mass of wires is far from aesthetically pleasing.




In accordance with the present invention a leg wire management apparatus


10


is provided that efficiently contains and conceals the cables and wires, as shown in

FIGS. 2 and 3

. The configuration in

FIG. 2

contemplates a table leg L that can be folded using folding mechanism F underneath the table work surface. The configuration in

FIG. 2

envisions that the table leg L is fixed to the work surface. The table T can include a number of brush bezels B pressed into the work surface through which the wires and cables pass to the underside of the work surface. The wire management apparatus


10


of the present invention is equally applicable to either configuration; although it can be advantageously utilized with the folding leg arrangement shown in FIG.


2


.




Referring to

FIGS. 3-5

, the table T is supported by two legs


5


, each carrying a wire management apparatus


10


. Each of the legs


5


is formed by a pair of leg posts


6


. As shown in

FIGS. 3-7

, the leg posts


6


are connected at a bend


7


to the feet


8


. The leg posts


6


are separated to define a gap or channel


9


. The wire management apparatus


10


is disposed within that gap


9


. As seen in

FIG. 4

, the wire management apparatus


10


forms an exit opening


11


at the bottom of the leg


5


adjacent the bend


7


. At the other end of the leg


5


, the wire management apparatus


10


defines an entry opening


12


, as shown in FIG.


5


. As depicted in

FIG. 2

, the various wires and cables are fed through entry opening


12


into the wire management apparatus


10


and exit the apparatus at opening


11


at the bottom of leg


5


. The wires and cables are very effectively managed in a visually appealing manner. Moreover, with the wires exiting the apparatus


10


at the feet


8


of the leg, it is easier and less obtrusive to carry the wires to the wall outlets.




A central component of the wire management apparatus


10


of the present invention is the legway


15


illustrated in

FIGS. 8-10

. The legway


15


constitutes an elongated tubular body


17


that is sized to reside within the gap


9


between the leg posts


6


, as described above. The tubular body


17


defines a semi-circular cutout


18


at the bottom end


19


that establishes the exit opening


11


depicted in FIG.


4


. The body also defines a notch


21


adjacent the top end


22


of the legway


15


, which corresponds to the entry opening


12


shown in FIG.


5


. Preferably, the notch


21


is formed by removing an approximately 180° segment from the tubular body


17


. The notch


21


extends below the top end


22


a sufficient distance to allow several wires and cables to be navigated into the legway


15


.




The transverse cross-section of the tubular body


17


can be best seen in FIG.


10


. The body


17


includes a forward portion


25


that is preferably arranged to face outward from the leg


5


relative to the table T. The body also includes opposite clamping arms


27


integrally formed with the forward portion


25


. The clamping arms define a leg recess


28


that is arcuate in shape to receive a corresponding one of the leg posts


6


. Most preferably, the leg recesses


28


are formed at a circular radius corresponding to the radius of the leg posts. The leg recesses


28


are limited to an arc segment of the circumference of the leg posts


6


that is sufficient to retain the leg posts within the recesses when the legway


15


is situated within the gap


9


.




The clamping arms


27


are configured to provide an outward force to clamp the legway within the gap


9


between the leg posts


6


. This clamping feature can be understood by reference to

FIGS. 11 and 12

. As shown in

FIG. 11

, the tubular body


17


is formed to have a natural or unstressed configuration in which the clamping arms


27


splay outward at an angle A relative to a centerline passing through the body. In other words, the tubular body


17


is initially formed with the clamping arms


27


at the described angle. The legway


15


is placed within the gap


9


by pushing the tubular body


17


between the leg posts


6


. Each clamping arm


27


defines a guide surface


29


that bears against a corresponding leg post as the body is pushed into the gap. The clamping arms are deflected inward toward each other in the direction of the arrows D until the tubular body


17


is situated entirely between the leg posts


6


, as shown in FIG.


12


. In this position, each leg post


6


is firmly disposed within a leg recess


28


of a corresponding clamping arm


27


. The tubular body can be readily removed from between the leg posts by pushing in the opposite direction.




With this feature, the legway


15


of the present invention can be readily added or removed to an existing furniture leg having more than one leg post. The legway can be disposed between any adjacent pair of leg posts forming a furniture leg structure. In some circumstances, it may be desirable to remove the legway entirely, leaving the basic leg


5


. The resiliently deflectable clamping arms


27


provide this capability.




As can be seen in

FIG. 12

, the tubular body


17


defines an outer envelope that is substantially contained within the space defined by the gap


9


between the leg posts


6


. Alternatively, the tubular body can be truncated or flattened at its forward portion


25


, and opposite the portion


25


, so that the legway is entirely disposed within the envelope formed by the leg


5


. One advantage presented by the legway


15


of the illustrated embodiment is that the tubular body


17


will not interfere with the normal operation of a folding leg. Since the legway is contained within the gap


9


of the leg


5


it is kept out of the way of the folding mechanism, such as mechanism F shown in FIG.


2


.




Returning to

FIG. 10

, the tubular body preferably includes a central rib


30


that projects to the interior of the legway


15


from the forward portion


25


. The rib


30


traverses substantially the entire length of the tubular body


17


, terminating at the circular cutout


18


, as illustrated in FIG.


8


. The central rib


30


divides the interior of the tubular body


17


into two wire/cable channels


33


,


34


. The two channels


33


,


34


provide a more organized approach to restraining the loose wires and cables, optimally preventing entanglement of the wires/cables.




In a further feature of one embodiment of the invention, the central rib


30


includes a rear flange


31


opposite the forward portion


25


. The rear flange


31


follows the outer contour of the legway


15


defined by the guide surfaces


29


of the two clamping arms


27


. Like the central rib


30


, the rear flange


31


extends along substantially the entire length of the legway


15


. The central rib


30


and rear flange


31


provide mechanical stiffness to the elongated legway


15


so that the tubular body


17


will not be distorted or bent when it is pushed into the gap


9


between the leg posts


6


. In addition, the rear flanges cooperate with the clamping arms


27


to define a pair of entry slots


35


,


36


. The entry slots


35


,


36


open into a corresponding wire channel


33


,


34


. In the preferred embodiment, the entry slots


35


,


36


are sufficiently wide to allow passage of an electrical cable, cord or wire.




With this feature, it is not necessary to snake the plug end of a wire or cable through the top end


22


of the legway


15


and to blindly navigate the wire/cable through the legway so that the plug end exits from the exit opening


11


at the bottom of the leg


5


. Instead, the wire or cable can be fed through one of the slots


35


,


36


into one of the channels


33


,


34


. The plug end of the wire/cable can then be easily passed through the exit opening


11


. Preferably, the slots


35


,


36


are wide enough to receive the wires/cables even when the legway is its operative position shown in FIG.


12


. Alternatively, the wires and cables can be fed into the legway


15


before it is positioned between the leg posts, although this approach may be more cumbersome.




In a further embodiment of the invention, the wire management apparatus


10


of the present invention contemplates means for providing a decorative or ornamental appearance. To achieve this benefit, the invention contemplates a cover plate


45


that is mounted to the legway


15


, as shown in FIG.


13


. The cover plate


45


is preferably in the form of a sheet of aesthetically pleasing material bent into an arc segment to correspond to the forward portion


25


of the tubular body


17


. The cover plate


45


forms elongated tangs


46


at the free edges of the plate. The tangs are configured to be pressed into correspondingly sized slots


40


formed in the tubular body, as depicted in

FIGS. 10 and 13

. Preferably, the tangs are held in place by friction and the natural springiness of the cover plate material. In addition, once the legway


15


is in its operative position, the leg posts


6


will also help retain the tangs


46


within the slots


40


. Alternatively, a form of press-fit engagement can be achieved between the cover plate and tubular body.




The cover plate


45


defines a circular cutout


47


at its lower edge to correspond to the cutout


18


at the bottom of the legway tubular body


17


. While the cover plate


45


can be a solid sheet of material, it is envisioned that the plate carry a decorative feature, such as feature


49


shown in FIG.


14


. In one embodiment, the decorative feature


49


can be a mesh configuration, although other aesthetically pleasing designs are contemplated.




The cover plate


45


is preferably readily removable from the legway


15


. In this way, different plates


45


can be provided for use with a single legway configuration. The cover plate can be color coordinated to match the office furniture, or provided with features to match the office decor. With the addition of the cover plate


45


, the legway tubular body


17


can essentially have any appearance. Alternatively, where the decorative feature


49


is a mesh configuration, the tubular body


17


can have a complementary exterior color or configuration.




In a specific embodiment of the invention, the tubular body


17


of the legway


15


is formed of a resilient high-density thermoplastic, a metal such as stainless steel, or other comparable material. The body material must exhibit sufficient resilience so that the clamping arms


27


can be repeatedly flexed without diminishing their outward clamping force. The legway of the present invention is particularly well suited to formation in an extrusion process. During the extrusion process, the clamping arms


27


are situated at the angle A depicted in FIG.


11


. The decorative cover plate


45


can also be formed of a plastic or a metal, such as stainless steel.




Again, in the specific embodiment, the tubular body has a width of 2.5 inches to accommodate a similarly dimension gap


9


between the leg posts


6


. The circular cutout


18


at the bottom of the body is formed at a radius of about 1.0 inch, while the notch


21


extends about 3.625 inches from the top end


22


of the body


17


. In this embodiment, the legway defines an entry slot


35


having a width of about 0.15 inches, while the opposite entry slot


36


is wider, at 0.28 inches. With this configuration, the narrower entry slot


35


can be reserved for narrower electrical cords and phone/data cables, while the larger slot


36


can accommodate larger cables, such as a printer cable.




While the invention has been illustrated and described in detail in the foregoing drawings and description, the same is to be considered as illustrative and not restrictive in character, it being understood that only preferred embodiments thereof have been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected.
