Bracket mounting system consisting of a mounting rail (11) with a number of single or parallel double slots (17) extending in the longitudinal direction of the rail and non-slotted intermediate spaces (19) located in between, as well as of brackets (12) with a curved hook (15) so as to be capable when inserted into slot (17) of rails (11) to be fastened to the rail in any required position, and with one or several supporting edges and/or lugs (26') arranged below hook (15) for supporting the bracket, and in which the upper side of the bracket is designed with a notch (21) acting as a pivot so as to co-operate during swivelling-in of fastening part (14) of the bracket into a slot (17) in rail (11), and in which on the one hand edge (21a) of notch (21) facing outward towards the room is curved and the lower rear edge (22) of the locking hook is curved, and in which the height of the fastening part of the bracket in conjunction with the curvatures of the outward facing edge (21a) of notch (21) and the lower rear edge are such that the bracket is, owing to three-point locking, i.e. 1) against the lower edge of a slot, 2) against the upper edge of a slot, 3) against some point on the front of the intermediate space above the slot or above the uppermost slot, constantly secured against inadvertent or intentional detachment also if the bracket is turned upward by a certain given angle. |
