The present patent concerns raised floors and the respective supports, and more specifically it concerns a new head with a reversible adapter for supports of raised floors.
At present, in order to create raised floors on supporting surfaces in general, first of all conveniently spaced supports are laid, on which the joists and/or panels making up the floor are subsequently placed.
Supports are known which are constituted by a base element suited to be rested on the ground and supporting the four corners of four panels arranged side by side.
The base element is generically cylindrical in shape and its underside is provided with an enlarged base, while its upper part is flat, orthogonal to the cylindrical part, and suited to support the elements of the raised floor.
The corners of the panels laid side by side to form the floor rest on each of said flat upper parts, commonly called heads.
Supports are known which comprise a base element and an element intended to adjust the height of the support, wherein said adjusting element comprises the head, on which the top panels of the raised floor rest, and is suited to be coupled with said base element and to adjust the height of the support.
For the construction of some raised floors, the panels do not rest directly on the supports but on wooden joists or metal sections. Said wooden joists or metal sections are laid and fixed on said heads, and the panels of the raised floor are laid on said wooden joists or metal sections.
In the case where the panels rest directly on said supports or heads, the flat upper part of said heads of the supports themselves is provided with partitions for centering and spacing the corners of said panels.
Said partitions are generally four, are arranged according to a cross-shaped configuration and radially with respect to the centre of said head, in such a way as to accommodate the corners of four panels placed side by side.
In the case where said supports do not have to support the corners of the panels but one of their sides, it is possible to remove one or more of said partitions by simply breaking them along pre-cut lines in proximity to their junction with said head. The document
In the case where wooden joists or metal sections are used between said panels and said supports, the flat upper part of the head of said supports is provided with seats, projections, partitions or other parts suitable for accommodating and fixing each wooden joist or each metal section.
These differences in the heads of said supports make it necessary to produce different supports or upper heads of supports for the different intended uses.
This makes it necessary to have different production lines, different moulds, and to keep supports or upper heads of supports in stock for the different applications.
In addition to the above, if during the installation of the raised floor it becomes necessary to change the laying procedure, for example inserting wooden joists or metal sections or laying the panels directly without joists and without section bars, supports or upper heads of supports suitable for the various applications must be available.
In order to overcome all the above-mentioned drawbacks, a new head with a reversible adapter for supports of raised floors has been designed and manufactured.
It is one object of the invention to provide a new head according to claim 1, that can be used directly with the panels of the raised floor and also with wooden joists or metal sections.
It is another object of the invention to provide a new head that does not require additional elements when it must be used with the panels of the raised floor or with wooden joists or metal sections.
It is another object of the invention to provide a new head that makes it possible to reduce the production costs of supports on which the panels of the raised floor can be directly rested or on which the wooden joists or metal sections suited to support the panels of the raised floor can be rested.
It is another object of the invention to provide a new head that makes it possible to reduce the space required in the warehouse to store supports suitable for various needs.
It is another object of the invention to provide a new head that during the installation of the floor allows the operator to rest the panels of the raised floor directly on the supports or to use wooden joists or intermediate metal sections with no need to replace any supports or parts of the supports.
These and other direct and complementary objects are achieved by the new head with reversible adapter for supports for raised floors, which is suited to support the panels of the raised floor directly resting thereon and suited to support and be connected with wooden joists or metal sections.
The new head comprises an upper element suited to be coupled with a base or lower element and an adapter suited to be coupled with said upper element.
Said upper element comprises a substantially cylindrical body, wherein the upper end of said cylindrical body, that is, the part intended to face upwards, is provided with at least one seat, for example but not necessarily circular in shape.
On the entirety or part of its external surface, said cylindrical body is provided with a spiral-shaped projection intended to create a thread or a screw suited to be coupled with the base or ring nut of known supports.
Said upper seat of said upper element is suited to accommodate and retain said adapter. Said adapter comprises a substantially flat body suited to be housed and removably retained in said upper seat of said upper element.
Said adapter thus has two opposite sides, a first side and a second side that are different from each other, and wherein said adapter is configured in such a way that it can be selectively accommodated in said upper seat of said upper element in two different ways, that is, with said first side facing upwards or with said second side facing upwards.
According to the present invention, on a first side of said adapter there are one or more partitions, substantially orthogonal to the flat side of the adapter itself and arranged radially with respect to the centre of the adapter.
Said partitions are preferably four and equally distributed around the centre of the adapter according to a cross-shaped configuration.
Said partitions are suited to centre and space the corners of the panels of the raised floor. Said partitions can be pre-cut so that they can be rapidly removed, or they can be detachable in any way, in the case where one or more of them is not required.
On the second side of said adapter there are one or more vertical elements extending vertically from said flat body of the adapter, for example two vertical elements or two sets of vertical elements parallel to one another and arranged in proximity to or at the level of the circular edge of the adapter.
For example, said vertical elements are arranged in pairs, wherein one vertical element of each pair is arranged in a position diametrically opposite the second vertical element of the same pair.
Said vertical elements are arranged in such a way as to retain a joist or section bar resting on the adapter and interposed between at least one pair of facing vertical elements.
Said vertical elements, like said partitions on the other side, can be removed according to the size of the joist or section bar.
Said vertical elements can be configured in various ways, for example with at least one substantially flat surface orthogonal to the flat body of the adapter, said flat surface being directed towards the centre of the adapter and suited to abut an edge of the joist or section bar placed on the adapter.
According to the invention, said vertical elements can also be configured with hooks or protruding parts suited to be coupled with the correspondingly shaped edges of the joists and section bars.
An innovative aspect of the present invention lies in that said adapter and said upper seat of the upper element are configured in such a way that the adapter can be selectively accommodated in the upper seat in two different ways, namely:
According to the invention, said adapter is housed in the seat and remain in a stable position simply thanks to their matching shapes: for example, said seat is circular and said adapter has a corresponding circular shape, so that it can be inserted into the seat.
Alternatively, according to the invention said adapter can also be constrained in the seat provided in the upper element through reversible means, for example through fixed joints or elastic tabs or other means.
The characteristics of the present invention are better clarified in the following description, which makes reference to the drawings that are attached hereto by way of non-limiting examples.
The new head (10, 10') comprises an upper element (100, 100') and an adapter (200, 200') suited to be coupled with said upper element (100, 100').
As shown in
The upper end (120) of said cylindrical body (110) can comprise an annular flange (130) or it can be without said annular flange, as shown in
Said upper end (120) is provided with a seat (140) configured to accommodate said adapter (200, 200').
Said adapter (200) comprises a substantially flat body suited to be removably housed and retained in said seat (140). For example, said flat body of the adapter (200) has a circular shape, or any shape, corresponding to the shape of the seat (140), so that, when the adapter (200) is correctly inserted into the seat (140), it is substantially flush with said flange (130) or in any case with the perimeter edge of said upper end (120).
Said adapter (200) preferably includes also at least one hole (201), preferably in a substantially central position, which is useful for the insertion of screwing tools.
On a first side (210) of said adapter (200) there are one or more partitions (230), substantially orthogonal to the flat side of the adapter (200), arranged radially with respect to the centre of the adapter.
In the examples of
Said partitions (230) are suited to centre and space the corners of the panels (F) of the raised floor, as shown in
On the second side (220) of said adapter (200) there are one or more vertical elements (240, 250) extending from said flat body of the adapter (200).
Said vertical elements (240, 250) are preferably arranged in pairs, or pairs of groups, parallel to one another and preferably, but not necessarily, arranged in proximity to or at the level of the circular edge of the adapter.
The distance between each pair of vertical elements (240, 250) actually determines the width of the joist/section bar that can be inserted and constrained between the vertical elements (240, 250).
In the examples of
In this example, a vertical element (240) has a surface (241) facing towards the centre of the adaptor (200) and substantially flat or in any case intended to abut the edge of a joist (T) or section bar (P) as shown, for example, in
In the same example shown in
Said vertical elements (240, 250) can also be drilled (242) so as to allow the insertion of means for fixing the joists or section bars, for example nails or screws.
Said second vertical elements (250) can conveniently be removed, for example manually broken, in the case where the width of the joist (T) or section bar (P) is greater than the distance between the vertical elements (240, 250) facing each other.
Said adapter (200) and said upper seat (140) of the upper element (100) are configured in such a way that the adapter (200) can be selectively accommodated in the upper seat (140) in two different ways, that is, so that said first side (210) faces upwards or downwards, meaning towards the inside of the upper element (100).
According to the invention, said adapter (200) is also shaped along the edge (260), for example with recesses (261) or projections or tabs or otherwise, in such a way that it matches the shape of said seat (140), to ensure that the adapter (200), even if it is removable, is positioned in the seat (140) in a stable manner.
