Abstract:
1. A fastening unit adapted to fasten an object to a profile element comprising: an anchoring element having an upper side and a lower side opposite the upper side; a support element on the upper side of the anchoring element; two connecting legs connecting a body of the support element and the anchoring element, each connecting leg having a retaining lug at a distal end; a spring element associated with the connecting legs; and a stop surface of the support element for engagement with the upper side of the anchoring element; wherein the spring element acts to push the anchoring element from the lower side away from the retaining lugs so as to bias the upper side of the anchoring element against the stop surface of the support element; wherein the profile element has sides extending in a longitudinal direction, a bottom that connects the sides, and an upper side, wherein the upper side is formed by a flange directed inwardly from each side, which flanges define between them a longitudinal slot having a width; wherein the anchoring element comprises an oblong metal anchoring element having a length that is greater than the width of the longitudinal slot of the profile element, and has such a width that the anchoring element with its longitudinal axis can be aligned with the longitudinal slot of the profile element, introduced into the profile element, and then turned to a transverse position relative to the longitudinal slot of the profile element, and with its upper side, to engage behind the flanges of the profile element, the anchoring element having a bore passing through it for receiving a male fastening element for fastening the object to the profile element when the anchoring element is in its transverse position; wherein the support element has a body, a central opening, and a washer element, the body connected to the anchoring element, the central opening substantially coaxial with the bore in the anchoring element, and the washer element engaging the upper side of the profile element when the fastening unit is in a mounted state on the profile element; wherein the two connecting legs are formed integrally with the body of the support element and extend each through an associated recess in the anchoring element, the recess adapted for one connecting leg of the support element being formed as a recess that extends from the upper side to the lower side of the anchoring element and adjoins the through bore in the anchoring element; wherein the spring element comprises an annular member, which annular member rests at diametrically opposite sides thereof against the retaining lugs of the connecting legs, and which annular member has two substantially semi-circular portions that are curved in such a way that its middle portion engages the underside of the anchoring member; wherein the retaining lugs prevent the anchoring element from being released from the distal ends of the connecting legs; and wherein the stop surface is constituted by an underside of the body of the support element.
