Description




BACKGROUND OF THE INVENTION




The present invention relates to the field of office furniture and workspace management systems. More particularly, the invention relates to a worksurface system.




A worksurface system is a system for providing a surface, typically horizontal, for a person to work at. Many worksurface systems are available in the prior art, the most common being a simple table or desk. Another type of worksurface system is provided within a workspace management system by cantilevering a worksurface off of the partitions or wall units within the workspace management system.




SUMMARY OF THE INVENTION




Briefly stated, the invention is a worksurface system which includes a rear and front worksurface. The rear worksurface has a front edge and a rear edge. The front worksurface has a front edge adjacent a user of the system and a rear edge generally parallel and adjacent to the front edge of the rear worksurface. The rear worksurface is supported by a plurality of rear posts. A plurality of brackets, each connected to a rear post, support the front worksurface. These brackets are adapted to allow the front worksurface to be adjusted to different heights in relation to the rear worksurface.




In accordance with a preferred embodiment, the system also includes a plurality of height adjustable legs which further support the front work surface. This preferred embodiment also includes height adjustable screens which are cantilevered off the rear posts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




Referring to the drawings,

FIG. 1

shows the preferred worksurface system


11


of the present invention. The system includes a rear worksurface


13


and a front worksurface


15


. The rear worksurface is supported by a plurality of rear posts


17


.




As best seen in

FIGS. 2 and 4

, the preferred construction of the rear posts


17


is with a right side


61


and left side


63


. Each side is made of a bent piece of metal with a front column of holes


24


and a rear column of holes


26


drilled therein. The bottom


65


of each side is angled away from the other side for stability. A bottom plate


67


is attached to hold the two sides together at the bottom. A spacer, not shown, is attached between the two sides to maintain a constant gap between the two sides. The top of each side includes a horizontal portion


69


with screw holes for attaching the rear worksurface


13


.




The rear posts


17


preferably include a leveling device, most preferably four threaded height adjustment glides


19


. Advantageously, the glides


19


include a slot or other feature on the top so as to make height adjustment relatively easy.




The rear worksurface


13


rests on top of the rear posts


17


. Preferably, the rear worksurface


13


includes a rounded front edge


16


and a back ridge


14


. Preferably, the front edge


16


is made of a pliable material to lessen the risk of fingers being pinched between it and the rear edge of the front worksurface. The back ridge


14


is used to mount tools such as the book ends


95


or tool stands


97


. Tool stands


97


, in turn, support a tool rail unit


99


on which items such as paper trays


101


and dividers


103


are mounted. The back ridge


14


is also beneficial in prevent small items from rolling or sliding off the back of the worksurface.




The front worksurface


15


also preferably includes a rounded front edge


18


. Also, the rear edge


20


is preferably made of a pliable material to lessen the risk of fingers being pinched.




The front and rear worksurfaces are preferably made from medium density fiberboard (MDF) with some type of covering, preferably a laminate, although a veneer of wood or some other coating can be employed. Alternatively, the worksurfaces can be made from solid wood, bent metal, a molded or shaped plastic, or a composite material.




The overall shape of the front and rear worksurfaces can be generally rectangular. Preferably, both worksurfaces are L-shaped as shown in FIG.


1


. Another way of looking at this is to see two rear and two front worksurfaces which are joined at a right angle with a 45° miter. In the most preferred embodiment shown in

FIG. 1

, the front worksurface


15


includes a cut-out for a keyboard tray


16


in the corner.




Alternative shapes, such as a C-shape, are also available, provided that the shape of the front edge of the rear worksurface is complimentary to the shape of the rear edge of the front worksurface. Some alternative shapes are shown in top view in

FIGS. 5



a-c


, wherein


111




a-c


represent the rear worksurface and


113




a-c


represent the front worksurface.




As best seen in

FIGS. 2 and 3

, the front worksurface is supported by brackets


23


which are preferably cantilevered off the rear posts


17


. The brackets


23


are configured to allow the front worksurface to be maintained at different heights relative to the rear worksurface. As shown by the dashed lines in

FIG. 3

, the front worksurface


15


can be adjusted to be above, below or even with the rear worksurface


13


.




With the exception of adjustments to level the worksurface, the rear worksurface is preferably not height adjustable. Alternatively, height adjustment may also be built into the rear posts if desired.




The height adjustability of the front worksurface is a desirable feature in that it allows one to set the front worksurface at the optimum height depending on the size of the user and the type of task being performed. It is also seen as desirable to provide this height adjustability for the front worksurface independent of the height of the rear worksurface. For example, when the front worksurface is lower than the rear worksurface, it provides a “terraced” worksurface wherein objects placed on the rear worksurface, such as reference books, telephones, and the like, are physically above and visually separated from those on the front worksurface. As such, they are less likely to interfere with the worker's use of the front worksurface.




Two other benefits of being able to maintain the rear surface at the same height while adjusting the height of the front worksurface is improved office aesthetics and utilities sharing. Keeping all of the rear worksurfaces in an office at the same height provides a more orderly look to the office. Also, when utilities distribution is provided through the worksurface system, as will be explained in more detail below, it is important for the worksurfaces to line up vertically.




Preferably this height adjustability is accomplished by having the brackets


23


able to be connected at different heights along the post


17


. Most preferably, this is accomplished through the series of holes


24


in the post


17


. Most preferably, the bracket


23


includes a vertical portion


73


which fits in the gap between the two sides


61


and


63


of the rear post


17


. This vertical portion


73


includes a top hole


75


and a bottom hole


77


which line up with holes


24


in both sides of the rear post. Top bolt


81


and bottom bolt


83


are inserted through two holes in the left side


63


, through the holes


75


and


77


in the bracket


23


and through two holes in the right side


65


. These bolts


81


and


83


may be secured in place by a nut on the end, by a cotter pin, by a biased pawl, or by any other releasable means.




The brackets


23


also preferably include an arcuate portion


85


and a horizontal portion


87


. The horizontal portion preferably includes screw holes through which the screws


89


pass into the bottom of the front worksurface


15


.




Preferably, the front worksurface is further supported by at least one leg


21


. Most preferably, the legs


21


are attached to the horizontal portion


87


of the brackets


23


with bolts


24


. Alternatively, the legs can be attached directly to the front worksurface.




The legs


21


are adapted to be height adjustable. Preferably, this is accomplished by providing a telescoping leg, i.e. a leg in at least two parts with one sliding within the other. Most preferably, the legs


21


comprise a top portion


43


which receives the bottom portion


41


in a cavity. Both portions


43


and


41


are preferably arcuate. The height adjustment is preferably made by passing a pair of bolts


47


through a pair of holes in the top portion


43


and through two holes


45


on the bottom portion


41


.




Alternatively, the legs can be made height adjustable through other means. For example, the leg may be pivotably attached to the front worksurface so that, as the height of the front worksurface is changed, the angle between the leg and the floor can be changed. Also, the leg may be configured with a lower portion that is telescopically and threadably received within an upper portion.




A cabling trough


91


is preferably attached to and supported by the top of the arcuate portion


85


of the brackets


23


. This trough


91


is open toward the top so that cables, such as computer cables or telephone lines, can be laid directly in. The trough


91


is preferably open on both ends for ready access. This trough


91


is intended to hold excess cabling, such as power cords and the like that would otherwise hang loose in an unsightly and possibly unsafe manner.




A cabling conduit


31


is preferably provided in the worksurface system


11


. The conduit


31


is divided into at least two channels, one for power cabling


34


and another for data and/or communication cabling


36


. Preferably, the power cabling is provided in a modular system such as that shown in U.S. Pat. No. 5,013,252. Fitted on the front surface of the conduit are outlets for power


35


and data/communication ports


33


.




Preferably, the conduit


31


is openable from the front to provide access most preferably lay-in access, to both channels. The conduit


31


is preferably fitted with removable end caps


32


. As a result, the conduit


31


may be either open or closed at the ends. It is desirable for the conduit


31


to be open at both ends when two or more worksurface systems are disposed adjacent one another so that cabling can be readily passed between the conduits. Alternatively, when a worksurface system is not adjacent another, it is desirable to have the ends of the conduit


31


be closed.




This conduit


31


is preferably attached to the front of the rear posts


17


just under the bottom of the rear worksurface


13


. Alternatively, the conduit may be connected directly to the underside of the rear worksurface or to the brackets which support the front worksurface. Locating the conduit directly below and toward the front edge


16


of the rear worksurface


17


is desirable in that it is readily accessible through the gap between the rear and front worksurfaces, especially when the rear worksurface is higher than the front worksurface.




The worksurface system of the present invention is also preferably equipped with at least one screen


55


. This screen


55


is supported by vertical standards


27


, which are, in turn, supported by brackets


27


attached to the rear posts


17


. The most preferable construction of the screens is a fabric sheet which encloses a top horizontal pole


56


and a bottom horizontal pole


58


. The screen is attached to the standards


27


by placing the poles


56


and


58


in the semicircular grooves


51


and


53


respectively. Bolts


54


hold the poles in the grooves.




The screen


55


is preferably height adjustable. This is accomplished by configuring the brackets


25


to be attachable to the rear posts


17


at different heights. Most preferably, this is done with a column of holes


26


towards the rear of the posts


17


. Alternatively, the bracket may be attached to the rear post at a fixed height and the standards be attachable to the brackets at different heights.




In addition to supporting the screen


55


, the standards


27


also support overhead storage units, such as shelf


105


. Alternatively, an overhead cabinet may be supported on the standards.




While other storage units may be attached to the worksurfaces, it is preferable to use a mobile, free-standing unit, such as the mobile pedestal unit shown at


107


.
