Abstract

Sliding device for sliding awnings, of the type consisting of stringers that slidely support a crossbar to which the tarpaulin of the awning is fixed, incorporating the stringers two overlapping chambers and running through the lower a skid and lift support. First sliding crosspiece, and some free skates supporting the successive crossbeams, through protrusions protruding through a lower slot of the stringers, fixing to said stringers respective end supports where are located driving and return crowns of a toothed belt, whose the upper branch runs through the upper chamber of the corresponding spar and its lower branch is fixed to the driving shoe of the first spar, the driving crown being driven directly or indirectly by an electric motor; characterized in that the toothed belt is replaced by a cable driven by adhesion to the throat of a motor pulley located in one of the end supports, which incorporates a hinged and lockable protection cover; in the body and in the cover of the motor pulley support, pairs of opposed and converging grooves of sliding and adjustable fixing are arranged in distance from the axes of tensioning pulleys acting on both branches of the cable; the pairs of grooves incorporate recesses that define seats for fixing the axes of the tensioning pulleys; in the opening of the cover of the support of the drive pulley are accessible recesses for fixing greasing bushings and supports for the rotary shaft of the drive pulley itself; the ends of the rotating shaft of the drive pulley are accessible externally to be mechanically fixed to the shafts of other drive pulleys of other side members of the same awning; the support of the motor pulley has some flanges to immobilize the fixed crossbar of the awning.
