This application is a continuation-in-part of application Ser. No. 09/082,128, filed May 20, 1998, now issued as U.S. Pat. No. 6,137,057.
The present invention relates to the electrification of structures, particularly office furniture and partitions, dividers and panels used to form office cubicles. Specifically, the invention concerns electrical raceway systems and devices to increase the usefulness and appearance of the systems.
As the cost of doing business has increased due to increases in costs of personnel, insurance, office space and the like, a trend for downsizing has developed. This trend along with the expanding presence of small businesses has created a pressure for economy in the workplace. Part of this economy is that a space may be required to fulfill more than one role. At the same time, an awareness of the effects of office aesthetics on morale and productivity has created a desire for pleasant and efficient workspaces. To meet these needs, attractive yet portable training, conference and office furniture has been marketed. Also, in many cases, open office plans must be divided into individual offices or workstations. Many arrangements are available to divide an open office space, including partition panels, systems furniture, and modular furniture.
Such workstations typically require specific features for maximum functionality: power supply, communication ports and keyboard or other support tools. However, in open office space, work structures may be placed in locations that are not easily accessible to the office space electrical and communication ports. Therefore, one challenge with providing power supply and communication access to the desk top of each workstation is wire management. Improper wire management can lead to interruptions in service, workplace hazards and poor aesthetics.
There is a growing need for improved components and systems for accommodating the distribution of electrical power along or in structures. Examples of electrical systems in office furniture panels and modular wall units are disclosed in U.S. Pat. Nos. 4,370,008, 5,231,562 and 5,451,101. Such systems include raceway enclosures for guiding electrical and communication wires from wall outlets to workstation structures. The raceway system facilitates the extension of both electrical and communication cables along the system in an efficient yet hidden manner, while permitting desired utilization of these cables at selected locations.
In spite of the benefits of such raceway systems, a need has remained for systems that improve the usability, flexibility, dependability, appearance and convenience of such raceway systems, particularly when used with tables or desks.
Briefly describing one aspect of the invention, a workspace structure assembly is provided. The assembly includes a table top structure having an upper and lower surface and supported on at least one leg. An elongated raceway is engageable to the structure and has a length, a transverse base and a pair of opposite upstanding sidewalls extending along the length to define at least one channel configured for retaining electrical wires. A locking element is provided to securely and detachably engage the raceway to an edge of the structure.
In one embodiment, the locking element includes an attachment element, a stud, a core and a locking lever. The stud defines a first axis along the length of the stud and has a threaded first end, an opposite second end and a shoulder between the first and second ends. The first end is insertable through an opening defined in the attachment element to engage a threaded hole in the surface of the structure. The core has a rounded outer surface and defines a thru-hole for receiving the second end of the stud. Means are provided for fixing the second end within the thru-hole. The core defines a second axis perpendicular to the first axis.
The locking lever includes a handle portion and a rounded camming portion. The camming portion defines a chamber for rotatably housing the core and a wall defining a groove in communication with the chamber for receiving the second end of the stud. The wall defines a contoured camming surface surrounding one end of the groove. The locking lever is rotatable about the second axis of the core from a first released position to a second locked position with the camming surface bearing against the shoulder to securely engage the raceway to the structure.
In another embodiment, a boot is provided for bridging a pair of electrical raceways. The boot includes an elongated tubular member having a semi-U-shaped cross-section. A pair of facing walls and a third wall connecting the face walls define a tunnel along a length of the member. A tunnel mouth extends along the length of the member in communication with the tunnel.
The member also includes a first end, a second end and a flexible midsection. The first end defines a first opening in communication with the tunnel. The first end has an inner surface and an outer surface and a first gripping member for gripping an end of the raceway. A second opposite end defines a second opening in communication with the tunnel, an inner surface, and outer surface and a second gripping member for gripping an end of the second raceway. A relatively more flexible midsection is connected between the first and second ends, which is bendible to assume various configurations. In one embodiment, the midsection includes multiple corrugations. In other embodiments, the gripping members include attachment projections defined on the inner surface of the first and second ends, which are configured to engage recesses defined in the raceways.
In another specific embodiment, a boot assembly is provided that includes a pair of boots for bridging a pair of raceways. Each boot includes a flexible section having a first end and an opposite end and a gripping portion connected to the first end. A flange inwardly projects from the inner surface of the opposite end of the boot. The boot assembly also includes connecting means for connecting the opposite ends of the boots. In one embodiment, the connecting means includes a U-shaped clip for maintaining the flanges in pressing engagement.
The invention also provides decorative plates engageable to the exterior surface of the raceway. The exterior surface of the raceway defines at least one elongate tongue and groove along the length. The tongue is spaced from the exterior surface and the groove is formed betweent he tongue and the exterior surface. The plates include at least one elongate rib extending along the length of the plate. The rib includes a projection receivable within the groove in cooperative interlocking engagement. In a specific embodiment, a second tongue and groove is adjacent the first tongue and groove and is contiguous with the first groove to form a substantially C-shaped cross-section. In other embodiments, the rib includes a second projection extending oppositely from the first projection so that the rib has a T-shaped cross-section.
In one embodiment, a cover is attachable to the raceway to occlude a portion of the channel. The cover includes an elongated face plate having an interior surface and an exterior surface. The face plate has a first portion and an opposite second portion, each portion extending along a length of the face plate. Attachment means are provided for attaching the first and second portions of the face plate to each of the opposite upstanding sidewalls with the interior surface facing the channel.
A flange extends from one of the portions of the cover plate and occludes an area behind the flange when the cover is attached to the raceway. The flange is relatively more flexible than the other elements of the cover and elastically deformable to allow access to the area. In some embodiments, the flange has a lower durometer than the other elements of the cover, such as the face plate or attachment means. In certain embodiments, the flange is integral with the face plate. In other embodiments the flange is adjacent the second portion and the face plate and is recessed to the face plate.
In another embodiment, one of the side walls of the raceway terminates in a lip, which includes a rounded surface having a radius. The attachment means of the cover includes a groove defined in the first portion that is configured for snap fit engagement with the lip. In some embodiments, a second of the side walls of the raceway terminates in an elongated attachment receptacle and the attachment means of the cover includes a rounded edge of the second portion that is receivable within the attachment receptacle. The rounded edge is configured for snap fit engagement within the receptacle. In specific embodiments the attachment receptacle defines a curved interior portion having an internal radius slightly larger than the radius of the rounded edge for mating with the rounded edge. In another aspect of the invention, the attachment means includes a hinge feature. The rounded edge of the second portion is rotatingly receivable within the attachment receptacle so that the cover is rotatable, about a longitudinal axis of the attachment receptacle, between an open position in which a portion of a channel of the raceway is exposed and a closed position in which the first portion is engaged to the raceway.
Accordingly, it is one object of the invention to provide improved electrical raceway systems for work spaces. These and other objects, advantages and features are accomplished according to the devices and assemblies of the present invention.
For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments 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. The invention includes any alterations and further modifications in the illustrated devices and described methods and further applications of the principles of the invention that would normally occur to one skilled in the art to which the invention relates.
The present invention provides electrical raceway systems and devices for raceways that enhance the functionality and aesthetics of workspaces. The locking elements provide instant, secure installation of raceways to desks, tables and the like. The locking elements allow quick release yet deter theft. The boots provide convenient bridging for wires between adjacent structures. Because the boots are open-sided, they can be installed and removed without disturbing the wires. The boots engage the raceways in a unique way that allows the use of a more flexible so that the boot is bendible to accommodate angles between the raceways. The more flexible midsection allows angles up to about 90°. The boots can also be modified so that they may be joined together to accommodate a greater distance between the raceways. The invention also provides covers for enclosing wires and cables within the raceway channel. The covers are engageable to the raceways in a snap fit engagement that provides secure placement of the cover and allows removal if access to the entire raceway is required. The covers are provided with a pliable flange that occludes an area behind the cover yet allows convenient access to the area for storing electrical cords and the like. Also provided are plates for covering the outside surface of the raceways. The plates have a decorative external surface and an internal surface engageable to the raceway in both right side up and upside down positions. The result of all of these devices is a modular, powered work station that is efficient, streamlined and safe from the hazards of loose wires.
An electrical raceway assembly 10 for attachment to a structure in accordance with a preferred embodiment of the present invention is depicted in
The raceway assembly 10 also includes a cover 40 attachable to the raceway 15 to occlude at least a portion of the channel 30 to shield or protect the contents of the raceway 15 and provide a pleasing appearance to the assembly 10. The cover 40 includes an elongated face plate 45 having an interior surface 46 and an exterior surface 47. The cover face plate 45 also has a first portion 50 and an opposite second portion 55. Each of the portions 50, 55 extend along a length l of the face plate 45. The length l of the face plate 45 may be equal or substantially equal to the length L of the raceway 15 to protect the enclosed wires W and provide a streamlined and aesthetically pleasing appearance to the structure. In some applications it may be desirable to provide several covers 40 for a raceway 15 if the raceway 15 is too long for a single cover 40 to be manageable and convenient.
Attachment means are also provided for attaching the cover 40 to the raceway 15. Preferably, the first and second portions 50, 55 of the face plate 45 are attachable to each of the opposite upstanding sidewalls 20, 25 so that the interior surface 46 faces the channel 30. The cover 40 is preferably configured for snap fit engagement with the raceway 15. For example, as shown in
In the embodiment shown in
Preferably, the rounded edge 56 is rotatingly receivable within the attachment receptacle 26 to facilitate snap fit engagement of the cover 40 to the raceway 15. In operation, the second portion 55 is first engaged to the raceway 15 at an angle that facilitates inserting the rounded edge 56 into the attachment receptacle 26 as shown in FIG. 6. The cover 40 is then rotated along the longitudinal axis Ar (
A flange 60 extends from an end of the cover 40 and along the length l of the cover 40. The flange 60 provides a pass through for excess cord stored in the area a behind the flange 60 to provide a neat and pleasing work space. In the embodiment of
Referring again to
Providing an elastically deformable flange 60 integrally formed with a face plate 45 that is sufficiently rigid to maintain engagement with the raceway 15 can be accomplished by a dual durometer cover 40. The flange 60 preferably has an average durometer which is relatively lower than the average durometer of other elements of the cover 40, such as the face plate 45 and/or the first and second portions 50, 55 of the cover 40. It is contemplated that the flanges 60 will be made of a thermoplastic material having a durometer of less than about Shore 80, preferably from about Shore 30 to about Shore 50, and other portions of the cover 40 will preferably be made of a thermoplastic material having a durometer at least about 15 units greater within the range of about Shore 65 to about Shore 95, preferably from about Shore 80 to about Shore 90. All durometer measurements are in accordance with ASTMD 224D Shore A, 15 second delay. The dual durometer covers of this invention can be obtained using methods known in the art, such as co-extrusion processes.
Although a distinct line 61 is shown in
The covers of the present invention may be formed of any suitable material that accomplishes the features of this invention. Preferably, the covers are composed of a thermoplastic material, including synthetic and natural rubbers, plastics and the like. The particular material of the covers is not critical so long as the covers have portions that are sufficiently rigid to maintain snap fit engagement with the raceway until a removal force is applied, and the flange 60 is elastically deformable to allow temporary access to an area behind the flange and then return to an undeformed state occluding the area.
Referring now to
The assembly 10′ preferably includes attachment means for detachably attaching the door 75 to the face plate 45′. In the embodiment shown in
Referring now to
Preferably, there is a difference in rigidity between the latch members 80 and the face plate 45′ to allow the shoulder portions 81 to be forced past the smaller dimensioned doorway 70. In one embodiment, the face plate 45′ is relatively more flexible than the latch members 80. This may be accomplished by using materials having characteristics that influence rigidity such as thickness and durometer. For example, the face plate 45′ may have an average durometer that is relatively lower than the average durometer of the door 75.
In this embodiment, the door 75 is substantially or nearly flush to the face plate 45 so that the assembly 10′ has a smooth and streamlined appearance, which does not detract from the overall aesthetics and appearance of the work space. At the same time, each of the doors 75 can be can be opened as desired to provide convenient access to portions of the raceway channel 30′ so as to permit access to power blocks or communication cables therein.
In some embodiments as shown in
In preferred embodiments, the raceway 115 defines at least one other channel 135 in addition to the first channel 130 as shown in FIG. 12. In some cases it is desirable to house electrical wires in one channel and communication wires in another. In this assembly 100, the raceway 115, also includes an open track channel 137 that defines an area a′. Area a′ is partially occluded by flange 160 when the cover 140 is attached to the raceway 115. In this preferred embodiment, the flange 160 contacts or approaches the surface 191 of the structure, such as a desk or table 190 as depicted in FIG. 13. The flange 160 provides a visible seal between the face plate 145 and the surface 191 yet allows access to the open channel 137 to store cords from tools, such as a computer or phone, on the table 190. The open channel 137 can also be used as an additional guide for wires and cords to desk top tools.
As shown in
A preferred fastener for securing the raceways of this invention to a structure is depicted in
In a preferred embodiment, the attachment element 205 includes a mounting plate 206 having a first end 207 attachable to the raceway 115. As shown in
The locking element 201 also includes a stud 215 more clearly shown in
The locking element 201 also includes a core 220 more clearly shown in
Means are provided for fixing the second end 217 within the thru-hole 222. In one embodiment, the means include a pin hole 224 defined in the core 220 and a pin 225 insertable into the pin hole 224 for engaging the second end 217 of the stud 215. Preferably, each pin 225 has a rounded end 226 for gripping the stud 215 as shown in FIG. 22. As shown in
Referring now to FIGS. 16 and 23-25, the locking element 201 includes a locking lever 230 having a handle portion 235 and a rounded camming portion 240. The camming portion 240 includes a chamber 242 defined in part by a wall 243 for rotatably housing the core. The wall 243 defines a groove 245 therethrough in communication with the chamber 242 for receiving the second end 217 of the stud 215 when the stud 215 is engaged to the core 220 and the core 220 is housed in the chamber 242. The wall defines a contoured camming surface 248 surrounding one end 246 of the groove 245. Following along arrow C in
As shown most clearly in
Preferably, the invention also includes a washer 250 mountable on the second end 217 of the stud 215 as shown in
Preferably, as shown in
Preferably, as shown in
Also, in preferred embodiments, the assembly also includes an angle iron as depicted in FIG. 16. The angle iron 260 is matingly disposed within one of the channels 137 along its length. Angle iron 260 defines a bolt hole 261 corresponding to the aperture 210 in the mounting plate 206. The angle iron 260 is held in position within the channel 130 by a lip 262. The angle iron 260 provides additional rigidity to the extruded raceway 115 to resist bending moments at the engagement of the plate 206 to the raceway 115.
It is understood that the attachment element 205 provides means to quickly attach or remove a raceway 115 from a structure, such as a table. A number of such elements 205 can be spaced along the length of the raceway 115 as necessary to support the raceway 115 and associated electrical elements. The attachment element, and particularly the mounting plate 206, permits supporting the raceway 115 projecting above the table as shown in
The present invention also provides devices for bridging a pair of electrical raceways. A preferred embodiment is depicted in
The member 301 includes a first end 320 defining a first opening 321 in communication with the tunnel 310. The first end 320 has an inner surface 323, an outer surface 324 and a first gripping member 325 for gripping an end of a raceway 115. The member 301 includes a second opposite end 330 defining a second opening 331 in communication with the tunnel 310. The second end 330 has an inner surface 333, an outer surface 334 and a second gripping member 335 for gripping an end 121 of a second raceway 120. A relatively more flexible midsection 340 is disposed between the first and second ends 320, 330. The midsection is bendible to assume various configurations. In a preferred embodiment, the midsection 340 is folded accordion-style to form corrugations 342, which enhance the flexibility of the midsection 340. The midsection 340 can assume angles up to about 90° as shown in FIG. 29.
The boot 300 also includes attachment means for attaching the first end 320 of the tubular member 301 to one of the raceways 115 and the second end 330 of the member 301 to the other raceway 120. In some embodiments, the attachment means includes an attachment projection 327 on the inner surface 323 of the first end 320 and a similar attachment projection (not shown) for the second end 330. The attachment projections 327 are configured to engage a recess 170 defined in the corresponding raceway 115, 120. Preferably, the projections 327 are adjacent the third wall 307.
The projection 327 addresses one challenge in creating a bridging member for a pair of raceways. The bridging member must firmly grip the ends of the raceways yet the bridging member must provide flexibility in the length and angles between the raceways. The gripping power of a channel-like enclosure is a function of the cube of the length to the point of gripping. If the enclosure gripped the raceway 115 at the edges 305a, 306a, the sides would have to be nearly 20 times stiffer than is necessary in this invention due to the projection 327. Therefore, the stiffness requirements of ends 320, 330 would make manufacturing of the flexible midsection between the two ends 320, 330 difficult. According to the present invention, a gripping projection 327 is provided near the base or third wall 307 of the enclosure. This provides a highly efficient method of gripping because the gripping point is near the base and therefore, this allows ends 320, 330 of a more flexible material.
The boots 300 of this invention are composed of any suitable material. In some embodiments, a dual durometer boot 300 is provided, in which the ends 320, 330 are composed of a material having an average durometer relatively higher than an average durometer of the midsection 340. Preferably, the boot 300 material is a thermoplastic for ease of manufacture, appearance, durability and the other desirable characteristics of those materials. Preferred materials include nylons and polypropylenes.
In some embodiments, an inner flange 343 is provided to increase the rigidity and gripping power of the ends 320, 330. The flanges 343 advantageously resist any reactive spreading forces generated by the corrugations 342 when they are forced into a curved displacement. A flange 343 projects inwardly from the inner surfaces 323, 333 of the boot 300. Preferably a flange 343 is provided at or adjacent each of the ends 320, 330 near the intersection of the end 320, 330 and the flexible section 430.
One advantage of this invention is that it provides flexibility in the angles and lengths between adjacent raceways that are to be electrically connected. In some cases, the raceway bridging device must have an extended length to accommodate the distance between raceways. In such cases, a boot assembly 300′ is provided as depicted in FIG. 34.
The boot assembly 300′ includes a number of boots having a total length sufficient to span the distance between the raceways. Each of the boot sections 300a includes a tubular member 301′ having flexible section 340′ with a first end 336 and an opposite end 337. Each boot section 300a includes a first gripping portion as described above connected to the first end 336 of the flexible section 340′. The opposite end 337 of each flexible section 340′ terminates in an inner flange 343′ inwardly projecting from the inner surface 323 of the boot section 300a. The flange 343′ has a first surface 344 facing the first end 336 of the boot section 300a and an opposite surface 337 as shown more clearly in FIG. 35.
The boot assembly 300′ also includes connecting means for connecting the opposite ends 340′ of the boot sections 300a. In one specific embodiment shown more clearly in
It will be appreciated that the boot assembly 300′ can be provided by modifying a pair of boots such as the one depicted in FIG. 32. Boot 300 can be modified by removing the second end 330 just to the right of the flange 343 at arrow C. Two such modified boot sections can be connected at the work site using the connection means of this invention.
In other embodiments, the invention also includes an end cap 390 for plugging the end of a raceway 115 as depicted in FIG. 32.
The raceways of this invention are preferably formed of a suitable rugged sheet metal material capable of being easily formed and shaped but not readily bent or abused. Any suitable tough, resilient material which possesses form-sustaining rigidity upon being formed and which exhibits sufficient flexibility to provide the connection upon installation as described may be used to form the assembly.
The raceways 115 of this invention are suited for engagement above and below a structure in either a facing or reversed orientation. One of the features of the raceways that allows this versatility is shown in
Preferably, the exterior surface 165 also defines a second elongate tongue 173 and groove 174 defined along the length of the exterior surface 165. The second tongue 173 and groove 174 is adjacent the first tongue 171 and groove 172 so that the second groove 174 is contiguous with the first groove 172 to form a groove pair 175 with a substantially C-shaped cross-section. This embodiment allows the raceway 115 to oriented in any direction and still serve as an attachment point for a device such as the boot 300. Preferably, the raceway also includes a second groove pair 185 defined along the exterior surface 165 of the raceway 115 and spaced apart from and substantially parallel to the first groove pair 175.
The present invention also provides an elongated plate 350 that is engageable to the tongue and groove pairs 175, 185 of the exterior surface 165 as shown in
The present invention economically and conveniently provides accommodations for electronic equipment in work spaces, which enhance the utility of office structures. The raceway assemblies of this invention guide wires to their outlets and provide table top access to power supply and communication ports. Conveniently, the raceway assemblies of this invention can be engaged above or below structures, facing forward or behind the structures. The devices of the present invention enhance the utility of office structures in an aesthetically pleasing manner and improve the quality of the work environment.
While the invention has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character. It should be understood that only the preferred embodiments have been shown and described and that all changes and modifications that come within the spirit of the invention are desired to be protected.
