Modular Utility Distribution Mounting System

The present invention relates to utility distribution systems, and in particular to a modular mounting system for the distribution of utilities at individual workstations.

Portable partition systems for open office spaces, and other similar settings, are well-known in the art. Individual partition panels or other demountable partition systems are interconnected in different configurations to form separate offices, workstations, or work settings. For such an office division system to be practical and usable for office workers, provisions must also be incorporated in such systems for the routing and delivery of office utilities to the individual work areas. Typically, office utilities are either preassembled within individual office panels, or are routed along raceways positioned at the top or bottom of the panel whereby user accessible outlets are provided at regularly spaced intervals. More recent, demountable wall systems incorporate a beltway positioned at worksurface height in which a modular utility distribution system is housed to provide office utilities such as electrical power, data, and communications at user access ports located at spaced intervals along the beltway. However, the placement of these user accessible outlets are often inconveniently positioned, inaccessible, or in insufficient quantity to fulfill the needs of the user.

As an attempted solution to alleviate the problems of inadequate accessibility of utility outlets, a variety of utility distribution modules have been introduced into the market. Generally, these modules incorporate within one housing a plurality of electrical outlets in combination with a plurality of data/communication connection outlets. The modules are then attached to or integrated with worksurfaces positioned within the individual workspaces of an office setting. These modules are typically mounted below the worksurface at a rear portion thereof such that accessibility by the user is gained either by an access door incorporated into the worksurface thereby dedicating valuable real estate for utility access or the user must inconveniently reach below and to a rear portion of the worksurface to gain access to the utility outlets.

Further, these utility distribution modules are generally preconfigured with a fixed number of utility outlets. Utility requirements of individual users usually is not consistent, and some users will require a large number of utility outlets while an adjacent user may have minimal requirements therefor. Single modules having a fixed number of utility outlets and a predetermined mounting position with respect to the worksurface detract from and run counter to the current trend of adaptability and flexibility of modular office systems designed to tailor the workspace to the needs of a particular user.

Thus, there is a need for a utility distribution mounting system which is tailorable to the individual needs of a workspace occupant. Further, such a utility delivery system should be tailorable with respect to its location within the workspace as well as tailorable to the quantity and configuration of utility outlets available to the user. Prior utility delivery systems have certain drawbacks and disadvantages, particularly with respect to the need for flexibility, positioning, and providing an optimum quantity of utility outlets for an individual user.

One aspect of the present invention is a modular mounting system for the delivery of office utilities from a utility distribution system of an office partitioning system to a worksurface position in an individual workspace. The modular utility mounting system comprises a mounting rail which includes an upper portion shaped for abutting attachment to a bottom surface of the worksurface an also includes a lower mounting portion which defines at least one mounting aperture therein. A utility distribution bracket is abutted to the lower mounting portion and includes a base and an upper frame connected to the base. The combined base and upper frame define a cavity shaped to closely receive a utility distribution block and further define at least one aperture for user access to the utility distribution block. The utility distribution bracket further includes an engagement member which extends through the mounting aperture of the mounting rail and closely engages the lower mounting portion of the mounting rail in a fastenerless fashion such that the utility distribution bracket is disengagable from the mounting rail and interchangeable with others of like utility distribution brackets.

Another aspect of the present invention is a modular utility system for the delivery of office utilities from an existing utility distribution system of an office partitioning system to a worksurface positioned in an individual workspace. The modular utility system comprises a mounting rail which includes an upper portion shaped for abutting attachment to a bottom surface of the worksurface and further includes a lower mounting portion defining at least one mounting aperture therein. A utility distribution module is abutted to the lower mounting portion of the mounting rail wherein the utility distribution module comprises a utility distribution block, a base abutted to a bottom of the utility distribution block and an upper frame connected to the base and defining with the base a cavity which closely receives the utility distribution block. The base and frame further define at least one aperture for user access to the utility distribution block and the upper frame includes an engagement member extending through the mounting aperture of the mount rail and closely engages a segment of the lower mounting portion of the mounting rail in a fastenerless fashion. The utility distribution module is disengagable from the mounting rail and interchangeable with others of like utility distribution brackets.

Yet another aspect of the present invention is a utility distribution kit particularly adapted for attachment to a worksurface positioned in an individual workspace for the delivery of office utilities from a utility distribution system of an office partitioning system. The utility distribution kit comprises at least one mounting rail which includes an upper portion shaped for abutting attachment to a bottom surface of the worksurface and also includes a lower mounting portion defining a plurality of mounting apertures arranged in a predefined pattern. Another element of the kit is at least one utility distribution module including a utility distribution block having a plurality of utility block connectors, a base which includes a plurality of apertures in a lower base surface and which is abutted to a bottom of the utility distribution block, and an upper frame connected to the base and defining therein a cavity closely receiving the utility distribution block. The base and the frame further define a plurality of apertures therearound for user access to the utility distribution block and the upper frame further includes an engagement member such that the engagement member can be extended through one of the mounting apertures for close engagement of a segment of the lower mounting portion of the mounting rail in a disengagable, fastenerless fashion. Another element of the kit is a conductive harness including a plurality of utility conductors having a harness connector terminated at one end thereof for connection to one of the utility block connectors of the utility distribution block and adapted at a second end for interconnection with the utility distribution system in the associated beltway.

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

As also shown in FIG. 7, utility distribution block 56 comprises a body 71 which is typically formed of a moldable resin in which utility conductors and interfacing contacts (not shown) are housed. In its preferred embodiment, utility distribution block 56 includes two utility connectors 68 at each end thereof and at each of its lateral sides has a module recess 67 having a module interface 69 at each end thereof. Utility distribution block 56 is typically identical to utility distribution block 12 found in utility beltway 10; however, utility distribution bracket 58 can be configured to receive a utility distribution block of any suitable utility distribution system.

FIGS. 7 and 10 show base 62 formed in a generally rectilinear cross-sectional configuration having an upper base surface 90 and a lower base surface 92 which are vertically separated by side walls 91. Upper surface 90 has two pairs of block apertures 94 formed therein wherein apertures 94 of each pair are laterally separated by locating segment 96. Each pair of apertures 94 is laterally centered in upper base surface 90 and are longitudinally disposed one from the other to correspond to mounting provisions on utility distribution block 56 as described more fully below. Upper base surface 90 also defines a plurality of mating apertures 93, each aperture 93 located proximate to the corners of base 62 for receiving bottom leg portions 78 of frame 60. Side walls 91 also have therein a hole 97 below each of mating apertures 93. Lower base surface 92, as shown in FIG. 10, has formed therein a plurality of mounting apertures 98 which correspond in size and position with mounting apertures 48 of mounting rail 22.

Referring now to FIG. 12, to assemble utility distribution module 24, a bottom portion 102 of utility distribution block 56 is abutted to upper base surface 90 of base 62. Utility distribution block 56 has depending from block bottom 102 of body 71 two pair of depending fingers 104 which define therebetween slot 106. Fingers 104 are received within block apertures 94 in upper base surface 90 such that locating segment 96 of upper base surface 90 is closely received in slot 106 formed by fingers 104. Closely received segment 96 provides lateral stability to utility distribution block 56 thereby preventing lateral movement of utility distribution block 56 when utility plugs are engaged and disengaged from utility distribution block 56. To complete the assembly of utility distribution module 24, upper frame 60 is placed over the combined distribution block 56 and base 62 such that leg bottoms 78 of upper frame 60 are received in mating apertures 93 of base 62 and are secured thereto with fasteners 95 engaged within holes 77 and 97 of upper frame 60 and base 62, respectively. As seen in FIGS. 6, 7 and 11, combined upper frame 60 and base 62 define cavity 64 wherein utility distribution block 56 is received and also define a plurality of apertures 66 therearound for user access to utility connectors 68 and module recess 67 of utility distribution block 56.

FIG. 13 shows a wire management bracket 110 attached to bottom surface 7 of worksurface 6. Wire management bracket 110, as illustrated in FIGS. 13-16, in its preferred embodiment comprises vertical web 112 having at an upper portion thereof an upper horizontal surface 113 adapted for abutting lower surface 7 of worksurface 6. Upper surface 113 includes therein holes 111 to receive fasteners 121 for attachment to worksurface 6, and also includes attachment tabs 114a and 114b extending from the side edges 119 of upper horizontal surface 113. A plurality of resilient fingers 116 extends outwardly and upwardly in a curved fashion from a lower portion of vertical web 112 wherein resilient fingers 116 have curved finger ends 120 formed to abut lower surface 7 of worksurface 6. Vertical web 112 and resilient fingers 116 define therein a horizontally extending trough 117 in which can be routed utility wires 14 to provide for the orderly management of utility wires 14 associated with office appliances and the like. Resilient fingers 116 are laterally spaced apart one from another forming slots 118 between adjacent ones of fingers 116 such that one or more utility wires 14 may be routed therebetween for the convenience of the user as shown in FIG. 17. A central notch 122 is formed at a midpoint of wire management bracket 110 wherein notch 122 is generally larger in size than slots 118 and adapted to accommodate therein clamp 124. Clamp 124 is typically a standard wire management clamp which is generally circular in cross section but may also be of rectilinear or other cross-sectional shape and is independently fastened to worksurface 6 by fasteners 126.

As shown in FIGS. 17 and 18, wire management bracket 110 can also be utilized in combination with mounting rail 22 to provide management of utility wires running proximate to modular utility system 20. As an alternate to the mounting of wire management bracket 110 directly to lower surface 7 of worksurface 6, rear attachment tabs 114a are inserted into accessory slots 44 of mounting rail 22 and wire management bracket 110 is then rotated in direction A as shown in FIG. 18 until front attachment tabs 114b become engaged in accessory apertures 46 of depending edges 38. Wire management bracket 110 also includes slots 115 in upper surface 113 which correspond positionally to slots 40 in mounting rail 22 to accommodate screws 42 for attachment of mounting rail 22 to lower surface 7 of worksurface 6 as shown in FIG. 3. Since mounting rail 22 has like flanges 36 and 38 on either side thereof, a wire management bracket 110 can, at the option of the user, be attached on one or both sides of mounting rail 22.

Referring now to FIG. 19, a decorative cover 130 is shown which can be attached to a lateral face of utility distribution module 24 in a snap-on fastenerless fashion such that decorative cover 130 can be readily added or removed by the user.

Chassis 148 includes a chassis top 154 having formed therein one or more mount clips 162 defining in combination with chassis top 154 horizontal slots 164 therebetween. Mount clips 162 are disposed on chassis top 154 in such a manner as to facilitate the attachment of chassis 26 to either mounting rail 22 or lower base surface 92 of base 62 wherein clips 162 are inserted in mounting apertures 48 or 98 and engage mounting segments 50 or 100 of mounting rails 22 or base 62, respectively. Chassis 148 also includes a back 156 and a bottom 158, each of which has formed therethrough slots 160. Chassis cover 150 is typically formed in a U-shape comprising a chassis front 172 and rearwardly extending chassis sides 166 from each end of chassis front 172. Each chassis side 166 has a knockout 168 and a tie tab 170 generally centrally positioned therein. Knockout 168 can be readily removed from chassis side 166 by inserting a screw driver in slot 169 and twisting knockout 168 for its removal. The resulting aperture from the removal of knockout 168 can be utilized for the attachment of a wire conduit for the routing of data/communication wires 16 therethrough to an interior portion of chassis 26. Alternatively, tie tab 170 having a hole centrally located therethrough can be bent at right angles to chassis side 166 thereby creating aperture 173 for the routing of data/communication wires 16. Wires 16 may be secured with respect to cover 150 by tying the wires utilizing conventional tie straps which encompass wires 16 and pass through hole 171. Chassis front 172 in its preferred embodiment has a rectilinear aperture 174 which is sized to accept the mounting of a data/communication distribution block (not shown). Such data/communication distribution blocks are of a readily available commercial configuration.

Turning now to FIG. 25, a utility distribution module 24 is shown wherein a duplex utility module 180 is received in module recess 67. In its preferred embodiment, utility distribution module 24 can accept two duplex utility modules within each recess 67. Duplex utility module has a block interface 182 at each end thereof for mating engagement with module interface 69 at either end of recess 67. Duplex utility module 180 further includes two receptacles 184 which are configured to receive the utility plugs of office appliances. To install duplex utility module 180, a user inserts module 180 in recess 67 along an axis parallel to a lateral axis of utility distribution module 24 and then slides duplex utility module 180 longitudinally until terminal interface 182 is completely engaged in module interface 69. Duplex utility module 180 has a plurality of contacts (not shown) therein to engage the requisite power, neutral, and ground contacts of utility distribution module 24 to provide a desired utility circuit for use by the office utilities employed by the user.

FIG. 26 illustrates the hermaphroditic alignment of longitudinally successive mounting rails 22 wherein alignments tabs 52 one rail 22 are received in alignment notches 54 of adjacent mounting rails 22.

FIG. 27 illustrates a typical configuration of utility distribution modules 24 and data distribution boxes 26 combined in a horizontal and vertical configuration. In the illustrated configuration, two mounting rails 22 are engaged in an end-to-end configuration whereby mounting clips 72 of each uppermost utility distribution module 24 are inserted through mounting apertures 48 and engage mounting segments 50 of each of mounting rails 22. The engagement of mounting segments 50 by mounting clips 52 permit configurations of utility distribution modules 24 in data distribution boxes 26 to be combined in a fastenerless fashion. However, those skilled in the art will appreciate that modules 24 and boxes 26 can be affixed one to the other and to mounting rails 22 using fasteners in a conventional manner. An in-line utility connector 192 having a connector interface 194 at each end thereof for mating engagement with end utility connectors 68 of horizontally adjacent utility distribution modules 24 interconnects the uppermost utility distribution modules 24. Splice plate 196 bridges in-line connector 192 and fasteners 197 are inserted therethrough to engage holes 198 on the adjacent ends of uppermost utility distribution modules 24. Locking clip 84 of the leftmost utility distribution module 24 engages end 35 of the leftmost mounting rail 22 to lock leftmost distribution module 24 in a fixed relationship with mounting rail 22. In a like manner, a lower utility distribution module 24 is attached to upper leftmost utility distribution module 24 such that locking clip 84 of the lower utility distribution module 24 engages an end of superjacent upper leftmost utility distribution module 24. A jumper harness 188 having harness connectors 190 which engage end utility connectors 68 of the upper and lower leftmost utility distribution modules 24 provide a continuous feed of utilities between utility distribution module 24. Utility harness 28 is connected to a utility connector 68 of rightmost utility distribution module 24 for the supply of utilities to the combined distribution configuration. A data distribution box 26 is shown depending from upper rightmost data distribution module 24 such that mounting clips 162 of data distribution box 26 engage mounting apertures 98 and mounting segments 100 of base 62 of upper rightmost utility distribution module 24. While FIG. 27 illustrates that utility distribution module 24 and data distribution box 26 are mounted to their respective superjacent structures in a right-to-left engaging manner, modules 24 and distribution boxes 26 can also be reversed and mounted in a left-to-right manner as a function of the symmetrical pattern of mounting apertures 50 and 98 in mounting rail 22 and base 62 respectively. Modules 24 and distribution boxes 26 are thus bi-directionally mountable.

FIGS. 28 and 29 illustrate alternate mountings of data distribution box 26. As shown in FIG. 28, data distribution box 26 can be mounted directly to mounting rail 22 by inserting mounting clips 162 through mounting apertures 48 and engaging mounting segments 50 of mounting rail 22. One or two data distribution boxes 26 can be mounted to each mounting rail 22. Alternatively, as shown in FIG. 29, data distribution box 26 can be mounted directly to either a vertical or horizontal surface such as worksurface 6 using fasteners 200 for insertion through slots 160 in either the back 156 or the bottom 158 of chassis 148.

FIGS. 30-32 illustrate alternate configurations of utility harness 28 for supplying utilities to modular utility system 20 and designated respectively as 28a, 28b, and 28c. Each configuration of utility harness 28 has a harness connector 202 which is adapted to connect to utility connector 68 of a utility distribution module 24. Harness 28a as depicted in FIG. 30 is a harness uniquely designed for use with the modular system 20 having an opposite end 204 wherein individual conductors 206 are unterminated for connection with a base mounted junction box 18 associated with the building structure. As shown in FIG. 31, harness 28b can be modified from a wire harness associated with a utility system housed within beltway 10 by removing a connector from one end thereof to reveal individual conductors 210 at opposite end 208 for connection within junction box 18. Utility harness 28c as shown in FIG. 32 has a harness end 212 terminated with an adaptor 214 which is configured for interconnection with a utility distribution block 12 positioned within utility beltway 10 of modular office system 2. Adaptor 214 is specifically configured to replace a module (not shown) such as duplex utility module 180 and engage module interface 69 in recess 67 of a distribution block 12 substantially identical to utility distribution block 56.

FIGS. 33-35 illustrate three variations of a satellite utility box 220, 222, and 224. Each satellite utility box includes a chassis 226 having a front 228, a bottom 230, and a back 232. A plurality of utility receptacles 234 are housed within chassis 226 and extend through front 228 for access by a user thereof. Satellite utility box 220 has a utility cord 236 extending from the back 232 and terminating with a utility connector 238 which is particularly adapted to engage a utility receptacle 184 in duplex utility module 180 as shown in FIG. 25. Satellite utility box 222 as shown in FIG. 34 has a utility harness 240 extending from back 232 of chassis 226 whereby harness 240 is terminated at a free end with an adaptor 242 which is configured for engagement in module interface 69 of recess 67 of utility distribution module 24. The satellite distribution box 224 as shown in FIG. 35 has a utility harness 244 extending from back 232 of chassis 226. The end of harness 244 is terminated with a connector 246 which is adapted to connect to and interface with end utility connectors 68 of utility distribution module 24. These different configurations of satellite utility box 220 permit user flexibility in the design and implementation of the particular utility distribution configuration incorporated at a workstation 4.

As shown in FIG. 36, a satellite utility box such as satellite utility box 220 is shown mounted to an upper surface of worksurface 6 and is clamped thereto utilizing the clamping apparatus 250 shown in FIGS. 37 and 38. In its preferred embodiment, clamping apparatus 250 comprises two threaded rods 252 having at an upper portion thereof an engagement element 254 which, as shown in FIG. 38 has lower wings 256 engaging tabs 258 on a lower portion of chassis back 232 and further includes an upper nose 258 engaging nose receptacle 260 positioned at an upper portion of chassis back 232. Each threaded shaft 262 depends from chassis 226 below chassis bottom 230. Clamping apparatus 250 also includes clamp arms 264, each of which includes cylindrical portion 266 which is sleeved over threaded shaft 262 as shown in FIG. 39. Each clamp arm 264 includes a horizontally extending arm 268 extending at right angles from cylindrical portion 266 and further wherein each arm 268 has a bearing surface 270 at an upper portion thereof for bearing against bottom surface 7 of worksurface 6. Retainers 272 have a slot 273 therein into which is received threaded shaft 262 to retain clamp arms 264 on threaded rods 252. Nuts 274 are threaded onto threaded shaft 262 to bear against retains 272 and to provide the requisite clamping force to maintain satellite utility box 220 in a fixed relationship with respect to worksurface 6.

Turning now to FIG. 40 which illustrates an alternative mounting of satellite distribution box 224 to a bottom surface 7 of worksurface 6 proximate to a front edge thereof, a mount plate 276 having one or more apertures 278 therein receives fasteners 280 for fastening mount plate 276 to lower surface 7. Mount plate 276 also includes flanges 282 formed at either side of mount plate 276 to engage slots 284 of chassis bottom 230 of satellite utility box 224 in a sliding fashion. The mounting of satellite utility box 224 in an inverted orientation to lower surface 7 at a front edge of worksurface 6 provides a convenient access to utility receptacles 234 by the user without dedicating a portion of the upper surface of worksurface 6.

In the foregoing description it will be readily appreciated by those skilled in the art that modifications may be made to the invention without departing from the concept disclosed herein. Such modifications are to be considered as included in the following claims, unless these claims expressly state otherwise.
