Abstract
A cable tray comprises a sheet metal central spine (10), comprising a channel web (12) and two channel flanges (13), and a plurality of cantilever bearer elements (11). Each bearer element is affixed to the spine by a spring clip (22) comprising two resilient tongues (23) adapted to clasp the spine between themselves. Each tongue has a barb formation (24) at its free end overlying a margin of the web, and a stud (25) extending into a hole (14) in the adjacent flange.
Claims17
A support for elongated building service supply means, of the kind comprising at least one spine and a plurality of discrete bearer elements affixed to said at least one spine, characterized in that each bearer element is affixed to said at least one spine by a spring clip fixedly associated with said each bearer element, wherein there are at least an equal plurality of locating formations on said spine each able to be engaged by a co-acting locating formation on said spring clip to thereafter resist disengagement of the bearer elements from the spine, wherein said spine has a cross-section such that said spine presents a top face having substantially horizontal margins and substantially vertical side faces and wherein each spring clip comprises two, upright spaced apart, resilient tongues adapted to clasp the spine between themselves and each having a barb formation at or near a free end of the tongues adapted to overlie a respective one of said margins.
A support for elongated building service supply means, of the kind comprising at least one spine and a plurality of discrete bearer elements affixed to said at least one spine, characterized in that each bearer element is affixed to said at least one spine by a spring clip fixedly associated with said each bearer element, wherein there are at least an equal plurality of locating formations on said spine each able to be engaged by a co-acting locating formation on said spring clip to thereafter resist disengagement of the bearer elements from the spine, wherein said spine is an inverted channel section comprising a channel web and two channel flanges, the locating formations on the spine comprise a longitudinally extending row of spaced apart holes in each of the channel flanges, each spring clip comprises a pair of upwardly directed, spaced apart, resilient tongues projecting from the clip's associated bearer element, each tongue has a barb formation at or near the tongue's free end directed towards the other and each tongue has a stud intermediate the tongue's ends projecting towards the other constituting the co-acting locating formations;
- wherein the tongues of each clip may clasp the spine between them with the barbs of the tongues overlying respective margins of the channel web and the studs on each tongue extending into a respective hole in the adjacent channel flange.
An elongate conductor support system bearer element comprising:
- a central snap-on clip;
- and
- at least two cantilevered arms extending from the clip in general opposite directions,
- wherein each bearer element is comprised of plastic as a one-piece member, and wherein the snap-on clip comprises two upwardly extending, resilient outwardly deflectable, tongues adapted to snap onto a spine of an elongate conductor support system, and wherein at least one of the tongues comprises an inwardly projecting stud adapted to be located in a hole of the spine for receiving the stud.
An elongate conductor support system bearer element comprising:
- a central snap-on clip;
- and
- at least two cantilevered arms extending from the clip in general opposite directions,
- wherein each bearer element is comprised of plastic as a one-piece member, and wherein the snap-on clip comprises two upwardly extending, resilient outwardly deflectable, tongues adapted to snap onto a spine of an elongate conductor support system, and wherein the bearer elements each comprise grooves located at a bottom of the clip for receiving free bottom ends of the spine.
An elongate conductor support system bearer element comprising:
- a central snap-on clip;
- and
- at least two cantilevered arms extending from the clip in general opposite directions,
- wherein each bearer element is comprised of plastic as a one-piece member, and wherein the snap-on clip comprises two upwardly extending, resilient outwardly deflectable, tongues adapted to snap onto a spine of an elongate conductor support system, and wherein the tongues each comprise a top end with an inclined top face for resiliently wedging the tongues apart during connection of the clip to the spine, and an underface for latching a top of the spine beneath the underface.
An elongate conductor support system bearer element comprising:
- a snap-on clip section;
- and
- at least two cantilevered arms, the cantilevered arms extending from the snap-on clip section in general opposite directions,
- wherein the bearer element is comprised of resilient material, wherein the snap-on clip section comprises two tongues, wherein at least one of the tongues is adapted to outwardly deflect and then resiliently snap inward towards the other tongue and onto a spine of an elongate conductor support system, and wherein the at least one tongue comprises an inward extending projection which is adapted to extend into a hole of the spine or which is adapted to extend onto a surface of the spine opposite an insertion direction of the snap-on clip section onto the spine.
