Abstract
These patents do not tackle minimally a further aspect which has recently become very important in the design of anchoring terminals. Said further aspect is relative the modalities of transfer of loads and the reduction of by dissipation of part of the energy developed by operators during the fall, in order to reduce the stresses, in particular the fastening means and the cover. The present invention, in particular, has been developed to reduce the action directly between-smessa to the fixing means of anchoring end and at the same time to allow the assembly of the terminal for anchoring at impluvi covers of two flaps, for example along the line at the centre of prefabricated deck beams "Y", or in the ridge caps with two pitches, especially if they are made with prefabricated beams to "Π" (pi). Due to its characteristics the terminal apparatus of the present invention can be usefully employed also in the case of flat coverings or for walls verticali mainly by exploiting its capacity of absorbing the energy; on the other hand its geometry adapted makes it suitable for being mounted in correspondence of partitions or other. Advantageously, the anchoring end of the present patent application provides of the elements, which are interposed in the chain of transmission of forces, which are at the same time can be orientated so as to adapt to the various shapes of the covers, such that, deform by plasticization, achieve the effect of reducing the loads transmitted by the connecting means with the operator to the fastening means to the cover. Another important effect of plasticization of said elements is to achieve a phase shift in the transmission of the loads. In order to understand the operation of the invention recall that it is known to experts in the art, in a structural element, fold constitutes a pre-shaping which, under suitable conditions of load, can be transformed into a plastic zipper. Therefore, according to a preferred embodiment of the invention the pivoting members for resting on the cover (3, 4), are made puncturing and bending a metal plate, in order to pre-form of plastic hinges designed to de-form under loads, thus suitable absorbing part of the energy of falling and by shifting temporally loads. For the same purpose, the support (2) can be made of materials which have undergone the pleats, thus increasing the effect of absorbing energy of the lateral members (3, 4) or even replacing them.
