Mounting structure for a power track

Claim 2

In combination with a relatively rigid, axially elongated, conductor-equipped track component for a power distribution system and which track component has transversely spaced side walls each equipped with an inwardly projecting hanger lip extending substantially from end to end thereof; structure mounting said track component along the outer surface of a ceiling wall in depending relation therewith and comprising: a support component equipped with laterally disposed hanger ledges respectively adapted to underlie and slidably engage said hanger lips to releasably interconnect said track and support components to enable the latter to support the former and at the same time accommodate relatively free axial displacements therebetween, an inverted generally U-shaped hanger component attached to such Ceiling wall in underlying relation therewith and having a hollow interior defining a cavity adapted to receive the upper end portion of said support component therein, and means releasably securing said hanger component to said support component and mounting the latter and any track component supported thereby in depending relation beneath such ceiling wall and including fastener structure operative between said hanger component and upper end portion of a support component received within said cavity, said fastener structure being effective to fixedly interrelate only said support and hanger components while any track component carried by said support component remains axially displaceable with respect thereto and also being effective to enable a track-carrying support component to be both secured to and released from said hanger component after the latter is attached to a ceiling wall.

Claim 3

The combination of claim 1 in which said support and hanger components are short in axial dimension relative to said track component and are axially displaceable with respect to each other upon release of said fastener structure with the result that a track-carrying support component can be secured to and released from an associated hanger component while both the track and hanger components remain in relatively fixed axial positions with the latter attached to a ceiling wall.

Claim 4

In combination with a relatively rigid, axially elongated, conductor-equipped track component for a power distribution system and which track component has transversely spaced side walls each equipped with an inwardly projecting hanger lip extending substantially from end to end thereof; structure for mounting said track component along the outer surface of a ceiling wall in depending relation therewith and comprising: a support component equipped with laterally disposed hanger ledges respectively adapted to underlie and slidably engage said hanger lips to releasably interconnect said track and support components to enable the latter to support the former and at the same time accommodate relatively free axial displacements therebetween, an inverted generally U-shaped hanger component adapted to be attached to such ceiling wall in underlying relation therewith and having a hollow interior defining a cavity adapted to receive the upper end portion of said support component therein, and means for releasably securing said hanger component to said support component to mount the latter and any track component supported thereby in depending relation beneath such ceiling wall and including fastener structure operative between said hanger component and upper end portion of a support component received within said cavity, said fastener structure being effective to fixedly interrelate only said support and hanger components while any track component carried by said support component remains axially displaceable with respect thereto and also being effective to enable a track-carrying support component to be both secured to and released from said hanger component after the latter is attached to a ceiling wall, the transverse dimension of said hanger component being no greater than that of said track component so as to be essentially within the transverse limits defined by the side walls thereof.

Claim 5

In combination with a relatively rigid, axially elongated, conductor-equipped track component for a power distribution system and which track component has transversely spaced side walls each equipped with an inwardly projecting hanger lip extending substantially from end to end thereof; structure for mounting said track component along the outer surface of a ceiling wall in depending relation therewith and comprising: a support component equipped with laterally disposed hanger ledges respectively adapted to underlie and slidably engage said hanger lips to releasably interconnect said track and support components to enable the latter to support the former and at the same time accommodate relatively free axial displacements therebetween, an inverted generally U-shaped hanger component adapted to be attached to such ceiling wall in underlying relation therewith and having a hollow interior defining a cavity adapted to receive the upper end portion of said support component therein, and means for releasably securing said hanger component to said support component to mount the latter and any track component supported thereby in depending relation beneath such ceiling wall and including fastener structure operative between said hanger component and upper end portion of a support component received within said cavity, said fastener structure being effective to fixedly interrelate only said support and hanger components while any track component carried by said support component remains axially displaceable with respect thereto and also being effective to enable a track-carrying support component to be both secured to and released from said hanger component after the latter is attached to a ceiling wall, the transverse dimension of said hanger component being no greater than that of said track component so as to be essentially within the transverse limits defined by the side walls thereof.

Claim 6

The combination of claim 3 in which said support and hanger components are short in axial dimension relative to said track component and are axially displaceable with respect to each other upon release of said fastener structure with the result that a track-carrying support component can be secured to and released from an associated hanger component while both the track and hanger components remain in relatively fixed axial positions with the latter attached to a ceiling wall, and in which said means for releasably securing said hanger component to said support component further includes a pair of axially elongated recesses respectively provided by said support component along its opposite sides and extending substantially from end to end thereof, said fastener structure including a pair of set screws carried by said hanger component and adapted to extend into the cavity defined thereby so as to seat within the respectively associated recesses of said support component.
