Abstract

A surface applied electrical raceway assembly comprising an extruded rear panel and an extruded cover which form a plurality of elongate compartments for deploying wires or other electrical conductors is disclosed. At any position along its length, the raceway can be attached to hanger brackets mounted on a wall. Continuous recesses including a tongue and groove configuration on the exterior of the rear panel and channels in at least one compartment permit attachment of the raceway to the hangers at any position and the installation of interfaces, such as standard duplex outlets, at any position along the raceway length. A storage compartment for receiving excess plug cables is also disclosed. The rear panel and the covers can be cut to length and together with accessory fittings can be used to form customized raceways with outlets at any desired location.

Claims

1. An assembly for use in deploying wires along a wall comprising a raceway with elongate compartments for housing the wires, the raceway comprising at least one elongate member with a rear panel, the elongate compartments being located along the interior of the rear panel, the rear panel having at least one elongate tongue and groove on the exterior, each tongue being spaced from the rear panel with said groove formed between the tongue and the exterior of the rear panel, the assembly further comprising a plurality of hanger brackets, each securable to the wall and engagable with the rear panel, each hanger bracket having at least one protruding lip received within the groove on the rear panel when the raceway is mounted on said hanger brackets secured to the wall, the rear panel of the raceway comprising an extruded member having a constant cross section along its length, the groove formed between the tongue and rear panel being continuous so that the raceway can be mounted on said hanger brackets at any position along its length.

2. The assembly of claim 1 wherein each hanger bracket has a plate disposable on the surface of the wall, each lip protruding from the plate.

3. The assembly of claim 2 wherein each hanger bracket has a plurality of hook members extending orthogonally relative to the plate, the hook members being configured for receipt in apertures in vertical rows on the wall.

4. The assembly of claim 3 further comprising a latch clip insertable into at least one of the apertures to anchor each hanger bracket to the wall, the hanger bracket including an opening for receiving the latch clip after the hook members are received within respective apertures.

5. The assembly of claim 4 wherein the latch clip comprises a U-shaped member having two legs, one leg being insertable through the hanger bracket opening.

6. The assembly of claim 3 comprising horizontal and vertical raceways, and horizontal hanger brackets and vertical hanger brackets, each hanger bracket having vertical hook members for securing the hanger brackets on the surface of a wall, the lip on the vertical hanger brackets extending vertically, the lip on the horizontal brackets extending horizontally.

7. The assembly of claim 6 further comprising a separator panel, the separator panel being attached to the assembly at the intersection of said vertical and horizontal raceways, the separator panel defining fore and aft sections so that wires in one compartment are restricted to the fore section and wires in another compartment are restricted to the rear section so that wires in separate compartments cross at an intersection, the wires in separate compartments remaining isolated at the intersection.

8. The assembly of claim 3 further comprising cover means, the cover means being attached to the rear panel and overlapping a lip at an edge of the rear panel to entrap the lip.

9. The assembly of claim 3 wherein each hanger bracket has two spaced apart said protruding lips each extending in the same direction, and each rear panel has two spaced apart said tongues extending in the same direction, the rear panel being mounted on the hanger brackets by initially positioning the rear panel with the grooves between the tongues and the exterior of the rear panel in alignment with and spaced from the hanger bracket lips and then by moving the rear panel toward the hanger bracket protruding lips until the lips are received within the grooves.

10. The assembly of claim 9 wherein one protruding lip comprises a U-shaped extension at one edge of the hanger bracket and the other protruding lip comprises a stepped section at the opposite end of the hanger bracket, the two protruding lips being in different planes.

11. The assembly of claim 9 wherein portions of the rear panel adjacent each protruding lip are spaced from the hanger bracket.

12. A raceway for deploying wires along a wall comprising a panel having means defining a plurality of elongate compartments for receiving the wires, the panel comprising an extruded member having a constant cross section along its length, the rear panel including elongate tongues at a plurality of positions on the exterior thereof, a groove being defined between each tongue and an exterior surface of the panel, each groove facing in the same direction, the rear panel including a pair of ribs spaced from an interior surface of the panel, a channel being defined between each rib and the interior surface of the panel, the open end of each channel facing the other channel, the channels being disposed along opposite edges of at least one of the elongate compartments, and receptacle brackets for attaching an electrical receptacle in an elongate compartment having channels disposed along the opposite edges thereof, free ends of each receptacle bracket being inserted within the channels, whereby the raceway can be secured on the wall by receipt of hanger brackets in the grooves on the exterior of the panel and panel interconnect means including electrical interface means can be attached to the raceway upon engagement of the electrical interface means with the ribs and channels.

13. The raceway of claim 12 wherein at least one divider wall extends from the interior surface of the panel to separate adjacent elongate compartments.

14. The raceway of claim 13 wherein the ribs in at least one compartment extend from spaced apart divider walls adjacent the juncture of the divider walls with the rear panel.

15. The raceway of claim 13 further comprising cover means for enclosing the elongate compartments.

16. The raceway of claim 12 wherein the panel interconnect means comprises a planar splice member insertable into the end of a channel.

17. The raceway of claim 16 wherein the electrical interface means further includes a fastener attachable to a wedge.

18. A raceway assembly for use in deploying cables along a wall and for positioning outlet receptacles at any arbitrary location along the wall, separate cables being confined to isolated areas, the raceway assembly comprising:

a plurality of rear panels, each comprising an extruded electrically conductive member having a constant cross section;

at least one divider wall extending transversely of each rear panel;

a plurality of covers, each cover comprising an extruded electrically conductive member having a constant cross section, each cover, each rear panel and the divider walls defining a plurality of closed elongate compartments for receiving the cables;

a plurality of protruding surfaces on the rear panel of the raceway defining a plurality of elongate recess means extending along the length of the rear panel;

panel interconnect means for forming a grounding attachment between multiple rear panels, including tabs configured for receipt within the recess means; and

cover interconnect means for forming a grounding attachment between each cover and a rear panel, the cover interconnect means including a protrusion configured for receipt within a recess means, whereby continuous said elongate compartments, each comprising an electrically grounded enclosure, can be constructed from a plurality of like components.

19. The raceway assembly of claim 18 wherein the divider walls are integral with the rear panels.

20. The raceway assembly of claim 18 wherein the recess means comprises outwardly facing grooves defined on the top and bottom of each rear panel and inwardly facing opposed channels defined on the interior of each rear panel.

21. The raceway assembly of claim 20 wherein the tabs on the panel interconnect means are configured for receipt within the inwardly facing channels.

22. The raceway assembly of claim 21 wherein the protrusion on the cover interconnect means is configured for receipt within a said outwardly facing groove.

23. The raceway assembly of claim 20 further comprising receptacle brackets for securing outlet receptacles within the raceway assembly, the receptacle brackets including flanges configured for receipt within the inwardly facing channels on the rear panels.
