Disclosed is a support system for the construction of raised floors with a walking surface spaced apart from a base, a lower rotor resting on the base, and an upper rotor resting above the lower rotor. The lower rotor has a spiral profile on which an upper sloping plane is defined, and the upper rotor has a spiral element on which a lower sloping plane is defined. The upper sloping plane is leant on the lower sloping plane so that, when the upper rotor rotates relative to the lower rotor, the upper rotor is raised or lowered relative to the lower rotor depending on the direction of rotation.

[0032] FIG. 8 is a side view of the element of FIG. 7 in section according to the plane B-B;

[0033] With reference to the appended figures, in particular FIGS. 1 to 3, 10 indicates a support system according to the invention for creating raised floors, so as to arrange a walking surface formed by wooden tiles or battens at a height from the base.

[0034] According to the embodiment illustrated herein, the support system 10 comprises: [0035] a lower rotor 12 [0036] an upper rotor 14 suitable for being supported above the lower rotor 12; [0037] a connection plate 16, supported at the top of the upper rotor 14; [0038] a first extension plate 18, positioned inferiorly to the lower rotor 12; [0039] a second extension plate 20, arranged inferiorly to the first extension plate 18 and suitable for resting on a reference ground.

[0040] The lower rotor 12 comprises a base disc 22 defined perimeterally by an edge 26 and having a central cylindrical body 24.

[0041] From the base disc 22 radially protrudes a projecting element 28 in which an end hole 29 is formed. A point 31 protrudes from the opposite side of the protruding element 28.

[0042] From the base disc 22 there protrudes vertically upwards a spiral profile 30 on which an upper inclined plane 32 is defined.

[0043] In the central part and in the peripheral part of the base disc 22, arcuate openings 23 are obtained through which water may be discharged.

[0044] The upper rotor 14 comprises an outer ring 34 from which radially projecting bodies 36 protrude at an angle equidistant from each other.

[0045] From the outer ring 34 starts a spiral element 38 on which a lower inclined plane 40 is defined.

[0046] The upper rotor 14 centrally comprises an annular support 42 with a central hole 44.

[0047] On the annular support 42 of the upper rotor 14 rests the connecting plate 16 which includes a vertical fin 17 and is suitable to allow coupling with tiles or wooden boards or with a support frame.

[0048] The spiral element 38 is also rigidly fixed to the outer ring 34 and the annular support 42 by means of radial elements 39.

[0049] In the lower portion of the spiral element 38, in correspondence with the radial elements 39, holes 41 are provided for the passage of any water.

[0050] The upper rotor 14 is supported on top of the lower rotor 12, so that the central cylindrical body 24 fits into the central hole 44.

[0051] Furthermore, the lower inclined plane 40 of the spiral element 38 of the upper rotor 14 rests on the upper inclined plane 32 of the spiral profile 30 of the lower rotor 12, as illustrated by FIG. 3.

[0052] By rotating the upper rotor 14 relative to the lower rotor 12 in a clockwise direction, the lower inclined plane 40 of the spiral element 38 slides on the upper inclined plane 32 of the spiral profile 30 and thus forces the upper rotor 14 to rise relative to the lower rotor 12.

[0053] The rotation of the two rotors 12, 14 is easily carried out by an operator who can, with one hand, lock the lower rotor 12 in position, grasping it by means of the protruding element 28, inserting a finger in the relative terminal hole 29, and with the other hand grasp and turn the upper rotor 14 by gripping the protruding bodies 36.

[0054] On the upper rotor 14, specifically on the outer ring 34, there are markings identifying various measures of the height to which the upper rotor 14 is brought in relation to the lower rotor 12.

[0055] The height actually reached is indicated by the tip 31 of the lower rotor 12 in correspondence to the corresponding inscription shown on the upper rotor 14.

[0056] The first extension plate 18 and the second extension plate 20 are optional and are used to raise the lower rotor 12 and thus the upper rotor 14 to a greater height.

[0057] A different element can be used as an alternative to the connecting plate 16, depending on the type of flooring to be installed.

[0058] There are snap-on mechanisms for coupling the lower rotor 12 to the upper rotor 14, the connecting plate 16 to the upper rotor 14, the first extension plate 18 to the lower rotor 12, and between the extension plates 18, 20.

[0059] Further variants and embodiments other than those illustrated above are possible and are to be considered within the scope of protection defined by the appended claims.

[0060] For example, the elements for gripping the two rotors can be of different conformation, as can the indications of the heights reached.
