FIELD

The present disclosure generally relates to a workstation, such as a workstation with a cable containment system for containing and concealing cables associated with electronic devices accessed from the workstation.

BACKGROUND

Workstations can support displays, user input devices, user output devices, and other electronic devices above a tabletop. It is often desirable to contain and conceal the signal and power cables associated with such devices. It may also be desirable to provide selective adjustment of the height of the tabletop so that a user may comfortably work at the workstation in a sitting position or a standing position.

SUMMARY

In one aspect, a height-adjustable work station comprises a base assembly comprising one or more cabinet modules. The base assembly has an upper surface, opposite left and right sides defining a width of the base assembly extending therebetween, and opposite front and rear ends defining a depth of the base assembly therebetween. The upper surface of the base assembly has left, right, front and rear edges at the junctions of the left side, right side, front end and rear end, respectively. A work platform is disposed above the base assembly. The work platform has a lower surface in generally opposing relationship with the upper surface of the base assembly. Opposite left and right sides define a width of the work platform extending therebetween, and opposite front and rear ends define a depth of the work platform therebetween. The lower surface of the work platform has left, right, front and rear edges at the junctions of the left side, right side, front end and rear end, respectively. A lift is operatively connected to the work platform and configured to selectively adjust an elevation of the work platform above the base assembly. The left, right and rear edges of the lower surface of the work platform generally overlie the left, right and rear edges, respectively, of the upper surface of the base assembly. Sizes and shapes of the left, right and rear edges of the lower surface of the work platform generally conform to the sizes and shapes of the left, right and rear edges, respectively, of the upper surface of the base assembly.
In another aspect, a work station comprises a base assembly including sides having upper and lower ends and an upper surface at the upper end of the sides and defining an access opening. The sides and the upper surface define an interior of the base assembly. A cable raceway is secured to the base assembly adjacent the access opening defined by the upper surface of the base assembly. The cable raceway includes a basket disposed in the interior of the base assembly. The basket has an open upper end adjacent the access opening and a bottom end defining a plurality of openings. The basket is configured to receive cables therein. A cover is configured to be movable between a closed position, in which the cover is received in the access opening and covers the open upper end of the basket to inhibit access to the basket through the access opening, and an open position, in which the cover is at least partially outside the access opening to allow access to the basket through the access opening.
Other objects and features will be in part apparent and in part pointed out hereinafter.

DETAILED DESCRIPTION

Referring to FIGS. 1-8, one embodiment of a workstation is generally indicated at 10. The workstation 10 includes a modular base assembly, generally indicated at 12, and a tabletop or desktop assembly, generally indicated at 14, mounted on the base assembly. The tabletop assembly 14 is positioned above the base assembly 12 for movement between a sitting position (FIG. 1), i.e., a lowered position, and a standing position (FIG. 2), i.e., an elevated position. More specifically, as shown in FIG. 2, the tabletop assembly 14 is supported on a lift 16 for lifting the tabletop assembly 14 to the standing position and lowering the tabletop assembly to the sitting position. In the sitting position, a work platform 20 of the tabletop 14 is positioned at a height for access by a human user of about normal size seated in a conventional office chair. In the standing position, the work platform 20 is positioned at a height for access by a human user of about normal size who is standing on the floor. The tabletop 14 is positionable to essentially any position between the sitting and standing positions to accommodate users of different sizes and preferences. The tabletop assembly 14 is configured to support electronic devices, such as the illustrated displays 22 and other user input/output devices (not shown) such as a keyboard, a mouse, a microphone, a speaker, etc. As explained in further detail below, the workstation 10 also includes a cable containment system, generally indicated at 25, which conceals and contains the power and signal cables for the electronic devices of the workstation in both the standing position and the sitting position. The routing of cables through the cable containment system 25 will be described in detail below and generally understood by those having ordinary skill in the art, but for clarity the cables are not shown in the drawings.
Referring to FIGS. 9 and 10, the modular base assembly 12 includes a plurality of cabinet modules 30, 32 that are arranged side-by-side to form the base assembly of the workstation 10. In the illustrated embodiment, the base assembly 12 includes one center cabinet module 30 and two side cabinet modules 32. Each of the cabinet modules 30, 32 has a width extending between opposite sides of the cabinet module, a depth extending from front to rear ends of the cabinet module, and a height extending from a bottom to a top of the cabinet module. The inboard side portion of each side cabinet module 32 is fastened to a respective side portion of the center cabinet module 30. In the illustrated embodiment, the inner side of each side cabinet module 32 is oriented at about a 45° angle relative to the width of the respective cabinet module and the sides of the center cabinet module 30 are oriented at about 90° angles relative to the width of the center cabinet module. Thus, since the cabinet modules 30, 32 are arranged side-by-side to form the base assembly 12, the width of each side cabinet module 32 is oriented at about a 45° angle relative to the width of the center cabinet module 30, and the widths of the two side cabinet modules are oriented at about a 90° angle relative to one another. In the illustrated embodiment, the center cabinet module 30 has a shallower depth than the side cabinet modules 32. As explained below, the shallow depth of the center cabinet module 30 allows a portion of the work platform 20 to overhang the legs of a user in the sitting position. Although the illustrated modular base assembly 12 is formed from three cabinet modules 30, 32 that are arranged side-by-side at 45° angles to the adjacent cabinets, other cabinet modules can be used to form modular base assemblies of other sizes, shapes, and arrangements in other embodiments. Thus, the base assembly can be selectively configured to suit the functional and/or spatial constraints of a given workstation by selecting from cabinet modules of different sizes and shapes and assembling them together in the desired manner.
As shown in FIG. 10, each cabinet module 30, 32 includes a framework 34 providing structural support to the module. Each illustrated framework 34 includes a bottom frame assembly 36, opposite side frame assemblies 38 secured to the bottom frame assembly, and an upper rear brace 39 extending between the opposite side frame assemblies. The side portions of each framework 34 are suitably configured for being fastened to another framework to thereby connect one cabinet module 30, 32 to another. For example, the side frame assemblies 38, the side portions of the bottom frame assemblies 36, and/or the side portions of the rear braces 39 may have pre-drilled holes or other preassembled attachment structures for connecting one framework to another with separate attachment hardware, such as bolts. Each side frame assembly 38 extends upward from the bottom frame assembly 36 toward the top of the respective cabinet module 30, 32. The rear braces 39 are secured to upper end portions of the side frame assemblies 38. As explained below, in the illustrated embodiment each rear brace 39 has a concave cross section that defines a channel configured to receive a portion of the cable containment system 27 therein. Thus, the rear braces 39 also constitute a cable containment support configured to support the cable containment system in the base assembly 12. The cable containment support 39 may be configured to support the cable containment system and not the corresponding cabinet module 30, 32.
The cabinet frameworks 34 are configured to support various features of the workstation 10 and are selectively configurable in many possible storage configurations. As shown in FIGS. 5 and 7-9, top panels 40, rear panels 42, rear joint covers 43, and side panels 44 are configured to be mounted on the frameworks 34 of the cabinet modules 30, 32 for enclosing an interior extending between the opposite sides of the base assembly 12. Suitably, the panels 40, 42, 44 and the joint covers 43 may be removably mounted on the frameworks 34 to allow selective access to the interior of the base assembly 12 for wiring electronic devices at the workstation 10, etc. Each framework 34 defines a storage area 45 (FIG. 10) extending widthwise between the respective side frame assemblies 38. The side frame assemblies 38 are configured to operatively mount drawers 46 and/or shelves (not shown) within the storage areas 45. In addition, cabinet doors may 48 may be mounted on the side frame assemblies 38 to enclose the storage areas 45. In the illustrated embodiment, the right side cabinet module 32 (the term “right” refers to the orientation of the base assembly 12 as shown in the front and top views of FIGS. 4 and 6) is configured as a two-drawer cabinet, the left side cabinet module (the term “left” refers to the orientation of the base assembly 12 as shown in the front and top views of FIGS. 4 and 6) is configured as a one-door cabinet, and the center cabinet module 30 is configured as a two-door cabinet. It will be understood that user could select different storage components and features for the cabinet modules 30, 32 in other embodiments.
Referring to FIG. 6, the side and rear edges of the work platform 20 of the tabletop assembly 14 generally overlie the respective side and rear edges of the modular base assembly. Moreover, the side and rear edges of the work platform 20 of the tabletop assembly 14 have sizes and shapes that generally conform to the sizes and shapes of the side and rear edges of the modular base assembly 12 (e.g., a size and shape that generally lies within the footprint of the sides and rear of the modular base assembly). The work platform 20 has a center portion and first and second side portions extending outward from the sides of the center portion at about 45° angles. The rear edge of the work platform 20 is located slightly inboard of the rear panels 42 of the base assembly 12 (e.g., the rear edge of the work platform 20 is spaced apart inboard of the rear of the base assembly by less than about 1.5 inches) and extends generally parallel to the rear panels. Similarly, the side edges of the work platform 20 are located slightly inboard of the side panels 44 of the base assembly 12 (e.g., the side edges of the work platform 20 are spaced apart inboard of the sides of the base assembly by less than about 1.5 inches) and extend generally parallel to the side panels. A front edge portion of the work platform extends forward past the ends of the cabinet modules 30, 32 to define an overhang under which the legs of a user may be positioned while seated.
Referring to FIGS. 11-13, the cable containment system 25 includes a tabletop cable enclosure or raceway, generally indicated at 50, which is mounted on the tabletop assembly 14 for movement with the tabletop assembly between the sitting and standing positions. As shown best in FIG. 12, the tabletop cable enclosure 50 includes a rear wall 52, left and right side walls 54, and four cover members 56 pivotably secured to the rear wall. Together, the rear wall 52, the side walls 54, the cover members 56, and the rear end portion of the work platform 20 define a substantially open interior of the enclosure 50. Tabletop cable enclosures having other configurations may also be used in other embodiments. The cover members 56 of the tabletop cable enclosure 50 are selectively pivotable relative to the rear wall 52 between a closed position (FIG. 3) and an open position (FIG. 11). In the closed position, the front end portions of the cover members 56 rest on front stops 58 of the enclosure 50 that extend upward from the work platform 20. As shown in FIG. 12, the stops 58 engage the front end portions of the cover members 56 in the closed position and position the front end portions of the cover members so that they are spaced apart from the work platform 20 to define openings or gaps 60 between the cover members and the work platform. The gaps 60 allow cables to pass from displays 22 and other user input/output devices on the tabletop assembly 14 into the interior of the cable enclosure 50 when it is closed. In the illustrated embodiment, ventilation holes are formed in each cover member 56 to prevent overheating of the cables within the enclosure interior.
The enclosure 50 is configured to conceal and route cables extending into the interior of the enclosure through the gaps 60 along the rear end portion of the tabletop assembly 14 and downward toward the interior of the modular base assembly 12. In one or more embodiments, power and/or signal receptacles or connectors (not shown) are permanently mounted on the enclosure 50 (e.g., on the interior of the rear wall 50 or on the rear end portion of the work platform 20). The source cables for the pre-installed receptacles and connectors may be routed into the base assembly 12 through cable chain assemblies 62 (FIG. 2) as described below. Cables that are not connected to pre-installed connectors in the enclosure 50 may be routed horizontally through the interior of the enclosure to holes 62 extending through the work platform 20. Suitably, the holes 62 are aligned with the cable chain assemblies 64, as shown in FIG. 2. The cables extend through the cable chain assemblies 64 and into the interior of the modular base assembly 12 as explained below. The cable chain assemblies 64 receive segments of the cables that are long enough to accommodate movement of the tabletop assembly 14 between the sitting position and the standing position. As is generally known in the art, the cable chain assemblies 64 are configured to fold the received cable segments into compact configurations that fit beneath the tabletop assembly 14 in the sitting position. The cable chain assemblies 64 are also configured to straighten the cable segments when the tabletop assembly 14 is moved to the standing position.
Referring to FIGS. 9, 10, and 14, an interior cable raceway, generally indicated at 70, is mounted on the frames 34 of the cabinets 30, 32 within the interior of the base assembly 12. The interior cable raceway 70 includes an elongate wire basket 72 (broadly, a raceway segment) mounted on each cabinet module 30, 32, and corresponding covers 74. In the illustrated embodiment, each wire basket 72 extends along the width of the respective cabinet module 30, 32 at the upper rear portion of the framework 34. More specifically, each wire basket 72 is mounted within the channel defined by the concave rear brace 39 of the respective cabinet module 30, 32. Interior cable raceways 70 may be installed at other locations within the cabinet modules in other embodiments. Cables from the cable chain assemblies 64 may be routed into the wire baskets 72 through the openings (FIG. 14) in the bottom or sides of the baskets. Upper surfaces of the covers 74 are generally coplanar with the upper surfaces of the top panels 40 of the modules 30, 32 to give an integral look to the modules. In the illustrated embodiment, the covers 74 are pivotable relative to the corresponding wire baskets 72 and the work platform 20 to open the covers, to provide access to an interior channel 78 (FIG. 14) of the raceway 70, and close the covers, the contain the cables therein. Alternatively, or in addition, the covers 74 may be removable from the base assembly 12 during installation of the cables to provide substantially open access to the interior channel 78 of the raceway 70. In some embodiments, the cover panels 74 are pivotably mounted on the cabinet modules 30, 32 by hinged retainers (not shown). The hinged retainers may guide pivoting movement of the cover panels 74 relative to the cabinet modules 30, 32 about a pivot axis through a range of motion. Furthermore, the hinged retainers may be configured to allow the cover panels 74 to be fully removed by moving the cover radially outward of the pivot axis while the cover panel is oriented at a specified pivot angle. The retainers may be configured to prevent the cover panels 74 from being removed when oriented at other angles in the range of motion besides the specified pivot angle. The interior cable raceway 70 may include one or more locks to selectively inhibit opening of the covers 74 to provide added security.
Each wire basket 72 is mounted on the respective cabinet 30, 32 near the top rear corners of the side frame assemblies 38. As explained above, the wire baskets 72 are received in the channels defined by the concave rear braces 39 of the frameworks 34. Any suitable fastener, locking mechanism, or retaining structure may be used to secure the wire basket 72 to the respective framework 34. Suitably, the wire basket 72 may be removably mounted on the respective framework 34. When the frameworks 34 are fastened together in side-by-side arrangement with one another, the wire baskets 72 align to form a substantially continuous cable raceway channel 78 extending along the rear end portion of the base assembly 12. That is, each of the rear braces 39 extends horizontally through the respective cabinet module 30, 32 and is positioned at about the same position in the respective cabinet module (e.g., at about the same height and about the same depth). Thus, the frameworks 34 operatively align the wire baskets 72 whenever the wire baskets are mounted on the frameworks and the cabinet modules 30, 32 are fastened together using the prefabricated attachment structures as discussed above. It can be seen that one or more additional cabinet modules comprising a wire basket or cable raceway segment mounted on a framework could be fastened to the illustrated side cabinet modules 32 using prefabricated attachment structures. When the additional cabinet modules are properly connected to the side cabinet modules 32 the additional wire baskets would align with the illustrated wire baskets 72 to increase the overall length of the cable raceway 70. Thus the modular cabinets used to form the base assembly 12 may be combined in various configurations to form a cable raceway having a length that is suitable for the needs of a given user.
In one embodiment, the cable chain assemblies 64 extend through openings in the tops of the cabinet modules 30, 32 to route the cables into the interior of the base assembly 12. The cables are routed from the lower end portions of the cable chain assemblies 64 into the interior of the base assembly 12′ through openings in the wire baskets 72′ and into the cable raceway channel 78. The cables are then routed horizontally through the wire baskets 72 to respective exit points. Because the bottoms of the wire baskets 72 include the openings along their lengths, the cables can exit the cable raceway channel 78 at essentially any point along the width of the base assembly 12. Thus, cables can exit the cable raceway channel 78 at respective exit points that are proximate a source receptacle or connector for the respective cable. For example, a signal cable may exit a raceway at a location near a source computer (e.g., a rack-mounted computer within the interior of the base assembly) or the like. Likewise, a power cable may be routed out of the wire baskets 72 at an exit location adjacent a power receptacle. It will be understood that cables may also be routed from the wire baskets 72 to receptacles or connectors located remote from the workstation 10.
In one or more embodiments, the modular base assembly 12 includes a secondary interior cable raceway (not shown) that is spaced apart from the primary interior cable raceway 30. For example, the rear end portions of the second frameworks may be shaped and arranged to define channels for receiving the secondary raceway near the bottom of the base assembly 12. In certain embodiments, a wire basket or other cable guide is mounted on the lower, rear portion of each framework 34 so that the cabinet modules 30, 32 define a substantially continuous secondary raceway channel along the rear of the base assembly 12 when fastened together as explained above in reference to the interior raceway 70. The primary and secondary raceways may be used to separately route different kinds of cables through the interior of the base assembly 12 to physically separate the cables and thereby limit electrical interference.
As can be seen, the illustrated workstation 10 provides a vertically adjustable work platform 20 on a base assembly 12 with configurable storage features. The tabletop assembly 14 is sized to generally correspond to the footprint of the base assembly 12, which may minimize pinch points of the device when the elevation of the work platform 20 is adjusted. Moreover, the work station 10 provides integrated cable management that conceals and organizes cables for worktop mounted electronic equipment, while allowing the electronic equipment to move vertically with the work platform 20 between the standing and sitting positions. The tabletop cable enclosure 50 organizes and conceals the portions of the cables that travel with the work platform 20, and the cable chains 64 contain the portions of the cables extending between the movable tabletop assembly 14 and the stationary base assembly 12. The interior cable raceway 70 routes stationary portions of the cables through the interior of the base assembly 12, and the base assembly conceals the cables. Each cable may be routed out of the interior cable raceway 70 at an exit location near the source receptacle or connector. When desired, the workstation 10 may also be configured to include a secondary interior cable raceway for maintaining physical separation between cables that could interfere with one another.
Having described the invention in detail, it will be apparent that modifications and variations are possible without departing from the scope of the invention defined in the appended claims.
As various changes could be made in the above constructions and methods without departing from the scope of the invention, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
