Description




BACKGROUND




The present invention relates to a shelf movably supported on a partition and adapted to move between a retracted storage position and an extended angled use position, such as may be used in office furniture to support working papers and readable materials, but which is not limited to only these items.




Functional storage is needed in modern office environments in order to efficiently deal with high volumes of paper and printed information in small office areas where space is at a premium. One way to increase usable space on a work surface is to support printed materials above the worksurface at a height that facilitates reading and viewing, and that at the same time allows work to be done on the work surface. For example, Ando patent U.S. Pat. No. 4,460,145 discloses a prior art book rest supported by levers in a four bar linkage arrangement for movement between an angled use position (

FIG. 1

) and a storage position (FIG.


2


). However, improvements are desired. For example, it is desirable to provide an arrangement that does not require a separate latch (see magnet 8 in Ando '145) to hold the shelf in a storage position, since the latch could release and cause materials stored on the shelf to be dumped. Further, an arrangement is desired that is stable without depending on any latch. Still further, a shelf arrangement is desired that is low cost, durable, functional, stable, and provides good positioning and spacing in all operative positions. Still further, a shelf arrangement is desired that includes relatively few parts, is readily operable and is inherently clear how to operate, yet that provides a clean aesthetic appearance. Also, a shelf arrangement is desired that is retrofittable and field-installable, and that is a modular, self-contained unit so that it is attachable to variety of furniture units without additional parts and pieces.




Accordingly, an apparatus solving the aforementioned problems and having the aforementioned advantages is desired.




SUMMARY OF THE INVENTION




In one aspect of the present invention, a document display shelf assembly is provided for use under a furniture unit mounted at a vertical height above a floor. The document display shelf assembly includes a movable shelf panel having a range of motion, a first support member adapted to be fixedly attached to the furniture unit at a first location, and a second support member with first and second sections adapted for pivotal attachment to the furniture unit and the shelf panel, respectively. The shelf panel is slidingly attached to the first support member and also pivotally attached to the second support member at the second section. By this arrangement, the shelf panel is slidingly supported by the first support member at a predetermined vertical distance below the first location throughout the range of motion and the shelf panel is pivotally supported by the second support member for vertical displacement. As a result, the shelf panel can be moved from a substantially horizontal storage position to a display position where the shelf panel is positioned at a vertical inclination.




In another aspect of the present invention, a document display shelf assembly is provided for use under a furniture unit mounted at a vertical distance above a floor, where the document display assembly includes a shelf movable between a substantially horizontal storage position and a predetermined vertically inclined display position. A first support member is adapted to be fixedly attached to the furniture unit, with the shelf being slidingly attached to the first support member. A second support member has a first section for pivotal attachment to the furniture unit and a second section pivotally engaging the shelf. At least one stop member is disposed on the second support member and pivotally movable therewith, so that movement of the shelf to the display position causes pivotal movement of the second support member to an abutting position relative to the furniture unit. By this arrangement, the stop member engages a surface of the furniture unit when the shelf is in the display position.




In yet another aspect of the present invention, an office furniture system includes a partition panel assembly, and a worksurface panel mounted to the partition panel assembly in a substantially horizontal orientation. A furniture unit is mounted to the partition panel assembly at a vertical distance above the worksurface panel. A display shelf assembly is mounted to the furniture system at a height between the worksurface panel and the furniture unit. The display shelf assembly includes a movable shelf, a first support member fixedly positioned relative to the furniture unit and slidingly attached to the shelf, and a second support member pivotally mounted relative to the furniture unit and pivotally attached to the shelf. The first and second support members are configured to support the shelf through a range of motion between a substantially horizontal storage position and a vertically inclined display position. The shelf is slidingly engaged by the first support member at a point positioned at a predetermined vertical height throughout the range of motion.




These and other features, advantages, and objects of the present invention will be further understood and appreciated by those skilled in the art by reference to the following specification, claims, and appended drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS




An office furniture system


20


(

FIG. 1

) includes a furniture unit


21


, such as a binder bin or fixed top shelf, mounted to a partition


22


. Other items can be mounted to the partition


22


, such as a worksurface


23


or the like, to define an open space


24


under a bottom


25


of the furniture unit


21


. A display shelf assembly/apparatus


19


is mounted to the bottom


25


of the furniture unit


21


, and includes a movable shelf


26


, a front bent-wire support


27


fixedly attached to the furniture unit


21


and slidingly attached to the shelf


26


, and a rear bent-wire support


28


operably pivotally attached to the furniture unit


21


and pivotally attached to the shelf


26


. The first and second support members


27


and


28


are configured to support the shelf


26


through a range of motion between a substantially horizontal storage position (

FIG. 2

) and a vertically angled display/use position (FIG.


1


).




The illustrated furniture unit


21


(

FIG. 1

) includes a primary or fixed top shelf panel forming the bottom


25


. It is contemplated that the bottom


25


can be incorporated into a binder bin


30


(shown in dashed lines) or other furniture accessory. It should be clear to a person of ordinary skill that any furniture unit having strength and defining an open space can be used to support the present inventive movable shelf


26


with supports


27


and


28


. In the illustrated embodiment, the open space


24


is defined under the bottom


25


and above the worksurface


23


. However, it is to be understood that the worksurface


23


is not required for use of the present inventive shelving apparatus.




It is contemplated that the present invention will work well with many different types of partitions. For example, the present invention can be used with Steelcase partitions sold under the trade names ANSWER, SEGMENT, and MONTAGE, as well as other partition systems.




The shelf


26


(

FIG. 3

) includes a panel body


31


, and a front edge cover


31


A that includes a perpendicularly protruding flange


3


lB. Where the body


31


is made of a wood product or otherwise requires added strength, edge guards


32


are attached along opposite side edges of the body


31


. The edge guard


32


includes a recess


33


defining an edge slot having a predetermined length, and further includes a hole


34


defining an edge pivot at a rear corner of the body


31


. Where the panel body


31


is made of metal or other strong material, or where the panel body


31


is light weight, the recess


33


and hole


34


may potentially be integrally formed in the body


31


without a separate reinforcing edge guard


32


. Bearings can be inserted into the recess


33


and/or into the hole


34


where improved lubricity is desired.




The front support


27


(

FIG. 7

) includes a first part


35


made from a metal wire or rod bent into the illustrated “U” shape, and a bracket


40


fixedly attached to the first part


35


. More specifically, the first part


35


includes a center section


36


, perpendicular side sections


37


, and inwardly bent pivot sections


38


. The mounting bracket


40


includes a U-shaped center trough


41


shaped to mateably engage the center section


36


, and further includes side flanges


42


and


43


with holes for screw attachment to a bottom surface of the bottom


25


. The mounting bracket


40


is spot welded or otherwise secured to the first support


27


to prevent undesired rotation of the first part


35


. A bearing can be snapped onto the inwardly bent pivot sections


38


instead of into the holes


34


if desired.




The rear support


28


(

FIGS. 4 and 6

) includes a first part


45


also made from a metal wire or rod that is bent into a “U” shape, and further includes a second one of the mounting brackets


40


. The rod part


45


includes a center section


46


, perpendicular side sections


47


, and inwardly bent pivot sections


48


. In rear support


28


, the rod part


45


is not attached to the bracket


40


, but instead rotatably engages the same. The center section


46


further includes a small looped section


49


formed in a center of the center section


46


. The looped section


49


is angled relative to the side sections


47


and forms a stop that engages a bottom surface of the bottom


25


as the shelf


26


is moved to the angled use position. (See

FIG. 5.

) The mounting bracket


40


includes an aperture


50


shaped to receive the looped section


49


. The aperture


50


is shaped to permit limited rotation of the looped section


49


as the shelf


26


is moved and the rear support


28


rotated. As illustrated, the aperture


50


is shaped so that the looped section


49


engages the side flange


42


when the shelf


26


is moved to its use position. For example, this is beneficial to prevent the looped section


49


from tearing into or wearing into the bottom


25


over time.




In operation, the shelf


26


is initially positioned in a storage position (FIGS.


2


and


5


), where the panel body


31


is oriented generally horizontally. In this position, the front support


27


is slid to a front of the side recess


33


, and both the supports


27


and


28


are in a generally vertical orientation. As the shelf


26


is pulled forward and downward, the panel body


31


slides along the recess


33


to a rear of the recess, and simultaneously, the rear support


28


begins to rotate. As the shelf


26


continues to move forward, a front edge of the shelf


26


moves at an increasing downward rate. As the shelf


26


moves toward the final angled use position, a front edge of the shelf


26


sweeps backward, thus positioning the shelf


26


at an optimal angled use position that is approximately under or slightly rearward of a front edge of the bottom


25


of the furniture unit


21


. It is noted that the relative position and angle of the shelf


26


to the furniture unit


21


, to the bottom


25


, and to the partition


22


can be changed by making dimensional changes to the supports


27


and


28


, such as by making the supports


27


and


28


longer and/or different shapes, and/or by redesigning the shapes and locations of slots and holes.




A modified shelving apparatus


19


A (

FIGS. 8-10

) includes several components identical to or similar to the components of shelving apparatus


19


. In shelving apparatus


19


A, components that are identical to or similar to apparatus


19


are identified with identical numbers along with the letter “A”. This is intended to reduce redundant discussion and reduce paperwork, and is not intended for another purpose. In shelving apparatus


19


A, the rear support


28


A is operably attached to the furniture unit for both pivoting and sliding movement, which results in a construction where the panel body


31


A is positioned closer to the bottom


25


A than in the shelving apparatus


19


.




More specifically, in shelving apparatus


19


A, the side sections


37


A of the rod part


35


A of the front support


27


A and also the side sections


47


A of the rod part


45


A of the rear support


28


A are made shorter, such that the panel body


31


A is positioned vertically closer to the bottom


25


A. However, the center trough


41


A is forwardly-elongated to form a recess


52


A. This allows the center section


46


A of rod part


45


A to slide forward a desired distance before the rod part


45


A is forced to pivot (see FIG.


10


). In turn, the panel body


31


A slides linearly forward a short distance (see

FIGS. 8 and 9

) before the supports


27


A and


28


A cause the shelf


26


A to begin rotation and translation to the final use position (FIG.


10


). To store the shelf


26


A, the above process is reversed. It is noted that a spring can be added to bias center section


46


A of the support


28


A to a rearward position in the recess


52


A to facilitate a smooth and comfortable movement of the shelf


26


A as it is adjusted between its use and storage positions. Also, a second stop


49


A′ can be added to prevent over rotation of the rear support


28


A when in the stored position.




A second modified shelving apparatus


19


B (

FIG. 11

) includes several components identical to or similar to the shelving apparatus


19


. The identical and similar components are identified with identical numbers but with the addition of the letter B. In apparatus


19


B, right and left pairs of support members


27


B and


28


B are used, and the long center sections (


36


and


46


of supports


27


and


28


) are eliminated. Instead, the front supports


27


B include a short section


36


B, side section


37


B, bent pivot section


38


B and a short bracket


40


B welded to section


36


B, and the supports


28


B include a short section


46


B, side section


47


B, bent pivot section


48


B, and a rotatably-supporting short bracket


40


B. an angled rod section


49


B forms a stop on the support members


28


B, and acts similar to the angled looped section


49


on rear support


28


by engaging the bracket


46


B and panel body


31


B′ when shelf


26


B is moved to its angled position. In side view, the apparatus


19


B looks like and functions like what is shown in FIG.
