Abstract
A support (1) for raised floors comprising a base (2), an intermediate element (3) and a head (4) on which raised floor portions rest. The support (1) is of the universal type, namely it allows selectively both a tilting movement of the head (4) on the intermediate element (3), and only a rotation movement of the head (4) on the intermediate element (3) about an axis perpendicular to a plane on which the base (2) rests. The intermediate element (3) is centrally provided with a circular element (80) that comprises a circular neck (81) from which the teeth (8) protrude outwards. The support (1) further comprises an open ring (100) adapted to be reversibly coupled to the circular neck (81) under the teeth (8).
Claims7
A support for raised floors comprising a base, an intermediate element and a head on which raised floor portions rest, wherein the support selectively allows both a tilting movement of the head on the intermediate element, and only a rotation movement of the head on the intermediate element about an axis perpendicular to a plane on which the base rests,
- wherein
- the base comprises a cylindrical cavity having an internal thread,
- the intermediate element has a cylindrical shape with an external thread and comprises a curved upper surface and central teeth, wherein each tooth protrudes outwards leaving a space below,
- the head comprises an upper portion with an outer upper surface which is flat, and a central compartment comprising a central surface with a central through hole,
- the head further comprises a lower portion with a curved surface,
- the through hole is provided with curved edges interrupted by loops which protrude outwards to allow the passage from below of the teeth through the through hole,
- the curved upper surface of the intermediate element slidingly coupling with the curved surface of the lower portion of the head,
- wherein
- the intermediate element is centrally provided with a circular element which comprises a circular neck from which the teeth protrude outwards,
- wherein the support further comprises an open ring adapted to be reversibly coupled to the circular neck under the teeth,
- wherein the tilting movement of the head on the intermediate element is enabled when the open ring is decoupled from the circular neck, and is disabled when the open ring is coupled to the circular neck, wherein, when the open ring is coupled to the circular neck and the internal edge of the through hole of the head is in contact with the external edge of the open ring, the head can only rotate on the intermediate element about an axis perpendicular to the plane on which the base rests, and
- the open ring is elastic to elastically deform in order to embrace the circular neck.
