Herein described is a starting block (10) for swimming pools comprising a base portion (12), constrainable to the perimetrical structure of the swimming pool at one of its head vertical walls, an upper walkable portion (14), supported by the base portion (12) and aligned with the head vertical wall of the swimming pool so as to be used as a platform by a swimmer, and one or more handgrips (16), protruding from the base portion (12) towards the internal part of the swimming pool and useable by the swimmer during the starting stages of a swimming competition. To the starting block (10) there is operatively connected a means (18) for supporting the feet of the swimmer, provided with a moving system which allows such support means (18) to move between a first operating position and a second rest position, wherein such support means (18) is outside the swimming pool.

1. A starting block for swimming pools comprising: a base portion, constrainable to the perimetrical structure of the swimming pool at one head vertical wall of said swimming pool;an upper walkable portion, supported by said base portion and aligned with said head vertical wall of said swimming pool
1. A starting block for swimming pools comprising: a base portion, constrainable to the perimetrical structure of the swimming pool at one head vertical wall of said swimming pool;an upper walkable portion, supported by said base portion and aligned with said head vertical wall of said swimming pool so as to be used as a platform by a swimmer;one or more handgrips, protruding from said base portion towards an internal part of said swimming pool and useable by a swimmer during starting stages of a swimming competition; anda support means for supporting feet of said swimmer, said support means being operatively connected to said starting block and provided with a moving system which allows said support means to move between an operating position, wherein said support means leans against said head vertical wall so as to form a step which is inclined with respect to said head vertical wall and facing upwards, and a rest position, wherein said support means is outside the swimming pool and does not represent an obstacle for swimmers who are inside said swimming pool or on said starting blockwherein said support means is made up of a plate constrained to said starting block by means of belts, and wherein said belts are in turn constrained to said starting block through a bar rotatably connected to a support framework removably constrained to said starting block so that, after a swimmer starts, said support means can be manually and easily removed from said starting block. 2. The starting block according to claim 1, wherein the inclination of said support means with respect to said head vertical wall is adjustable so as to always form an ideal angle for maximum efficiency of a thrust action of a swimmer during a starting stage of a backstroke swimming competition. 3. The starting block (10) according to claim 1, wherein said support means, in an operating position, is configured so as to be at least partly immersed in said swimming pool. 4. The starting block according to claim 1, wherein said belts are adjustable length-wise to modify the depth of said support means (18) with respect to an edge of said swimming pool. 5. The starting block according to claim 4, wherein a length-wise adjustment of said belts is obtained through a step-by-step adjustment mechanism with a plurality of positions, installed on said bar and on said relative support framework. 6. The starting block according to claim 5, wherein said step-by-step adjustment mechanism comprises two reels, integral with each end of said bar, on which each single belt is wound, at each of said reels there being provided a toothed ring nut, operatively connected to said bar through a spring so that said toothed ring nut may exclusively perform an axial movement with respect to said bar so that, when it is pushed by said spring, said toothed ring nut being configured so as to be engaged with a shaped block portion of said support framework for blocking rotational movement of said bar with respect to said support framework, thus avoiding a winding/unwinding of said each single belt with respect to said reels, and when said toothed ring nut is moved manually along an axial direction of said bar to overcome a force of said spring, there occurs a disengagement of said toothed ring nut from a corresponding shaped block portion, thus making possible an operation of winding/unwinding each single belt with respect to the relative reel.
