Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) Further features and advantages of the invention will become more evident in light of the detailed description of a preferred but not exclusive embodiment of a head for supports of raised floors according to the invention, illustrated by way of non-limiting example with the aid of the accompanying drawings, wherein:

(2) FIG. 1 represents a support for raised floors with a head according to the invention in axonometric view;

(3) FIG. 2 represents the support of FIG. 1 in sectioned view;

(4) FIGS. 3 and 4 represent details of a head according to the invention.

DETAILED DESCRIPTION OF SOME PREFERRED EXEMPLARY EMBODIMENTS

(5) With reference to the mentioned figures, and in particular to FIGS. 1 and 2, it is disclosed a head 1 for supports 2 of raised floors.

(6) As is known, the head of a support is the part of the support on which the building elements that constitute the raised floor rest.

(7) In this sense, the head 1 of the invention comprises a support body 4 and a tilting element 5 which rests on it. The latter has a flat surface 6 at the top for supporting building elements such as, for example, tiles, planks or the like.

(8) From the figures it is clear that not all the upper part of the tilting element 5 constitutes the flat surface 6. Indeed, this feature should not be considered as a limiting feature for the present invention. What matters is that at least one portion of the upper part of the tilting element 5 is at least partially flat in order to favour a correct support of the building elements.

(9) According to another aspect of the invention, the tilting element 5, as its name suggests, must be able to move with respect to the support body 4. In this sense, the latter has the upper surface 8 provided with a cavity 9 counter-shaped on a spherical cap. At the same time, the tilting element 5 has in its lower part, as can be seen in FIG. 3, a portion 10 shaped as a spherical cap for being laid movably on the upper surface 8 of the support body 4.

(10) In other words, the reciprocal movement between the tilting element 5 and the support body 4 is favoured by the spherical cap shaping of the lower part of the tilting element and by the counter-shaping according to said spherical cap of the upper surface 8.

(11) This configuration, moreover, facilitates the self-levelling of the floor since the weight of the tiles or the like resting on the tilting element 5 forces the latter to move with respect to the support body 4 and to arrange itself with an inclination in accordance with such weights.

(12) According to a further aspect of the invention, the portion 10 shaped as a spherical cap of the tilting element 5 identifies, in plan projection, a circular crown close to the perimeter edge 12 of the same tilting element 5. In other words, in the lower part of the tilting element 5 there is a circular crown portion 10 which is shaped like a spherical cap and which in fact identifies a spherical cap crown. It is close to the perimeter edge 12 of the tilting element 5, leaving the manufacturer the advantage of freely shaping the central part of the lower portion of the tilting element 5 itself.

(13) This also entails further advantages.

(14) First of all, the support surface of the tilting element 5 on the support body 4 is in any case particularly extended being constituted by the area of the circular crown identified by the portion of spherical cap.

(15) Still advantageously, the displacement of the portion of spherical cap which generates the movement on the periphery, the thickness of the portion of spherical cap necessary to obtain certain degrees of inclination of the tilting element 5 will be less than that required if the cap were totally made involving also its central part. In other words, the cutting of the central part of the cap does not prevent the element 5 from tilting on the support body 4, but making it less thick.

(16) According to another aspect of the invention, the support body 4 comprises a protrusion 15 emerging from its upper surface 8 and having threaded side walls 16. In the drawings it can be seen that this protrusion 15 is substantially a cylinder, but this should not be considered a limiting characteristic for the invention.

(17) At the same time, the tilting element 5 is provided with a through hole 17 which can accommodate the protrusion 15 to make it accessible.

(18) The head 1 then also comprises a ring nut 18 having the inner surface 19 threaded to mesh with the thread of the side walls 16 of the emerging protrusion 15. The lateral surface 20 of the ring nut 18 is moreover shaped to abut against the inner surface 22 of the through hole 17 of the tilting element 5.

(19) To sum up, therefore, there is a ring nut 18 which meshes with a protrusion 15 emerging from the upper surface 8 of the support body 4. The tilting element 5 is interposed between the ring nut 18 and the upper surface 8 of the support body 4 so that it cannot be separated from the support body 4.

(20) It can be deduced that the tilting element 5 is in any case free to move, but a complete screwing of the ring nut 18 onto the protrusion 15 realizes, as shown in FIG. 4, a thrust on the tilting element 5 towards the support body 4 which causes its stabilization, preventing any movement thereof. In other words, advantageously, the screwing of the ring nut allows to pass from a mobile head 1 configuration to a fixed head 1 configuration.

(21) Still advantageously, it is evident that the switch from the fixed head 1 configuration to the mobile head 1 configuration is reversible simply by unscrewing the ring nut 18. In particular, still advantageously, the passage from one configuration to the other can be carried out any number of times without any problem.

(22) However, the process is advantageously simple and typically executable without the need for adequate instrumentation.

(23) Moreover, the ring nut 18 does not necessarily have to be separated from the head 1 since it is sufficient to unscrew it only partially from the protrusion 15, thereby avoiding having accessories detached from the remainder 1 which would be easy to lose and would also create problems in warehouse management.

(24) Still advantageously, the fact that the head 1 is not very thick thanks to the displacement of the shaped portion 10 of the tilting element 5 towards its periphery allows the ring nut 18 and the protrusion 15 to be of limited dimensions.

(25) According to another aspect of the invention, the lateral surface 20 of the ring nut 18 is shaped like a truncated cone. At the same time, the inner surface 22 of the through hole 17 of the tilting element 5 is counter-shaped like a truncated cone.

(26) In this way, advantageously, the screwing of the ring nut 18 automatically and easily guides the tilting element 5 towards the support body 4 realizing the desired support and making the two elements stably coupled.

(27) From what has been said it is evident that the object of the invention is also a raised floor comprising: a plurality of supports 2 having a base 31 which can be positioned on a support surface and a head 1 operatively coupled to the base 31. a plurality of building elements forming the floor (not visible in the drawings) and configured to be laid on the head 1 of one or more supports 2.

(28) The head 1, in such case, is exactly like the one described so far, and a precise description thereof is omitted since it would be repetitive of what has been said so far.

(29) In light of the foregoing, it is understood that the head and the floor of the invention both achieve the prefixed purposes.

(30) In particular, the head can be both tilting and fixed, thereby facilitating the management of the supports.

(31) The switch between the tilting head configuration and the fixed head configuration is reversible at any time, repeatable for any number of times and executable without proper instrumentation.

(32) There are no separate accessories, therefore the management of the components is also simplified compared to known equivalent heads.

(33) The invention might be subject to many changes and variants, which are all included in the appended claims. Moreover, all the details may furthermore be replaced by other technically equivalent elements, and the materials may be different depending on the needs, without departing from the protection scope of the invention defined by the appended claims.
