Fastening unit

A fastening unit for fastening an object to a profile element,

• the profile element comprising:
• side walls extending in a longitudinal direction,
• a bottom that connects the side walls, and
• an upper side that is formed by a pair of opposing flanges, each flange extending inwards with respect to a respective sidewall, the flanges defining between them a longitudinal slot;
• the fastening unit comprising:
• a washer element, adapted to be placed on the upper side of the profile element,
• an oblong anchoring element having a threaded bore, the oblong anchoring element being spaced apart from the washer element, and adapted to be placed inside the profile element, beyond the flanges thereof, and
• a support element, interconnecting the washer element and the oblong anchoring element;
• wherein the support element comprises a first layer of vibration isolating material arranged on an underside of the washer element and a second layer of vibration isolating material arranged on an upper side of the anchoring element, and
• wherein the oblong anchoring element and the second layer of vibration isolating material each have a width that allows them to be aligned with the longitudinal slot of the profiled element, inserted therein, and then turned to receive the flanges of the profile element between the first layer of vibration isolating material and the second layer of vibration isolating material, so as to provide, at least in a fastened state of the fastening unit, a barrier for vibrations between the washer element and the flanges of the profile element and between the oblong anchoring element and the flanges of the profile element.
