Heated towel rail radiator comprising a fixed body and at least one support element for hand towels, said at least one support element being constrained in rotation to said fixed body by means of at least one hinge on which articulation means comprising a linear actuator are acting which are configured in such a way as to act on said support element to make it rotate along an axis of rotation (y) relative to said fixed body between a closed position and at least one open position, wherein it is rotated by an angle greater than and not equal to 0°, preferably up to 45°, said radiator being characterised in that said articulation means comprise a connecting rod, associated with said hinge by means of a timed coupling, and said linear actuator acting on said connecting rod and constrained to said fixed body, wherein the connecting rod has a first fixed end constrained in rotation with said hinge, and a second end, opposite to the first end, and a timed seat obtained in said first end, wherein said hinge has a pivot having a timed pin shaped in such a way as to couple and fit firmly into said timed seat of the connecting rod, wherein said timed seat of said connecting rod comprises at least one indentation having an axis of symmetry (s'), said axis of symmetry (s') being oriented relative to a first axis (t) passing through the ends (111, 112) of said connecting rod by a fixed angle (α) lower than 0°, preferably up to -10 °, in particular equivalent to -5 °, in that said linear actuator has a first end, constrained in rotation to said second end of said connecting rod, and a second fixed end constrained in rotation with said fixed body of the radiator, in that when said support element is in said closed position said first axis (t) is oriented by a first angle (α) relative to a second fixed axis (s) passing through the fixed ends (111, 122) of said connecting rod and of said linear actuator equivalent to said fixed angle (α'), in that when said support element is in said open position, said first angle (α) is greater than 0 °, preferably between 15 ° and 45°, preferably equivalent to 20°. wherein the connecting rod has a first fixed end constrained in rotation with said hinge, and a second end, opposite to the first end, and a timed seat obtained in said first end, wherein said hinge has a pivot having a timed pin shaped in such a way as to couple and fit firmly into said timed seat of the connecting rod, wherein said timed seat of said connecting rod comprises at least one indentation having an axis of symmetry (s'), said axis of symmetry (s') being oriented relative to a first axis (t) passing through the ends (111, 112) of said connecting rod by a fixed angle (α) lower than 0°, preferably up to -10 °, in particular equivalent to -5 °, in that said linear actuator has a first end, constrained in rotation to said second end of said connecting rod, and a second fixed end constrained in rotation with said fixed body of the radiator, in that when said support element is in said closed position said first axis (t) is oriented by a first angle (α) relative to a second fixed axis (s) passing through the fixed ends (111, 122) of said connecting rod and of said linear actuator equivalent to said fixed angle (α'), in that when said support element is in said open position, said first angle (α) is greater than 0 °, preferably between 15 ° and 45°, preferably equivalent to 20°.
