Fastening assembly

A fastening assembly for fixing an object to a profiled element with flanges which bound a longitudinal slot between them, in particular a profiled element of the C-section type, which fastening assembly comprises:

• a metal washer element, which has a bearing face that is arranged for resting against the outside of the profiled element,
• an elongated metal anchoring member, which is situated on the underside of the bearing face of the washer element and has axial end parts, and
• a support for the anchoring member, which support is connected to the washer element, possibly detachably, and which support bears the anchoring member,
• the fastening assembly having between the washer element and each axial end part of the anchoring member an accommodation space which is accessible from the side of the fastening assembly, each accommodation space being for the accommodation of a flange of the profiled element, in such a way that the fastening assembly with its anchoring member can be aligned with the longitudinal slot and the anchoring member can be inserted through the longitudinal slot into the profiled element, and in such a way that subsequently after turning of the fastening assembly, the anchoring member—in a pre-assembly state—extends at an angle relative to the longitudinal slot, so that the flanges are situated in the accommodation spaces and the anchoring member grips behind the flanges of the profiled element,
• wherein the anchoring member and the washer element can subsequently be tensioned towards each other in order to fix the fastening assembly to the profiled element,
• wherein the support comprises a head with one or more connecting members, which connecting members, engage with the washer element, and furthermore comprises legs, each extending from the head in a direction away from the washer element to a bottom end of the corresponding leg situated below the anchoring member,
• wherein the support below the anchoring member comprises one or more spring members, which are supported upon the bottom ends of the legs and engage onto the anchoring member from underneath and resiliently support the anchoring member from underneath, and
• wherein each connecting member has an upstanding trunk and resilient arms projecting laterally from the trunk, the trunk extending through an aperture in or along the outer periphery of the washer element and the resilient arms engaging with the upper side of the washer element.
