The present invention refers to the field of the signalling and barrier systems, such as for example for regulation of road traffic, of alignments of circulation ways and barriers of particular zones in the traffic way, comprising a plurality of modules, in particular in the form of signalling blocks, and similar devices.
The present invention further refers to a process of handling of said signalling and barrier system.
The prior art includes different solutions of traffic signalling devices of blocks type in general, also known as “jerseys”, and devices of type signalling blocks and circulation ways, provided so that can be simply placed upon the pavement, without retention or fixation thereto.
Considering that it is desirable that such blocks present a minimum height that renders them substantially visible by incoming traffic, one of the problems associated with this type of devices is therefore a respective stability standing and, function thereof, weight and volume.
In this context, it is known to produce this type of devices in synthetic material and confining an interior space.
Document U.S. Pat. No. 5,836,714 discloses a control barrier system comprising a module of block type adapted so that can be retained laterally with neighbouring blocks thereby forming a substantially continuous succession that extends along a barrier direction. Said module extends along a direction and presents a lateral section with a shape of triangular type, with a posterior wall developing along a generally vertical direction and a frontal wall developing along a generally oblique direction. According to a preferred embodiment, said module is provided so that the posterior and frontal faces can be collapsed, thereby reducing the occupied volume to the thickness of said posterior and frontal faces.
Document U.S. Pat. No. 6,086,285 also discloses a control barrier system that comprises a barrier module defining a chamber for ballast. In particular, said frontal and posterior faces are adapted so that the modules can be disposed with same directly opposing front faces, thereby completely occupying a cubic-type volume.
Document U.S. Pat. No. 6,669,402 B1 discloses a protection barrier system for absorbing impact of similar type. Said barrier module presents engagement means developing along most part of the height of module of respective lateral edges, in particular engagement means that include a projection-like element on one side and a cavity-like element configured in corresponding manner on the other side.
Document EP 2393986 B1 discloses a protection barrier with water ballast that comprises modules adapted so that can be laterally retained by a plurality of engagement points along the height, and so that provide that any two neighbouring modules can be arranged at an angle. Moreover, according to an embodiment, two of said substantially similar modules can also be disposed one on top of the other.
Document U.S. Pat. No. 9,016,668 B1 also discloses a barrier whereby any two substantially similar modules can be vertically stacked and present a connecting element.
Document WO 2015/135044 A1 discloses a barrier that comprises barrier modules presenting an open base and frontal and posterior walls that narrow from the base towards the top and thereby enable the modules to be stored by successively stacking ones within the others.
Document U.S. Pat. No. 9,677,233 B2 discloses a barrier system of the type of the present invention, wherein each barrier module presents generally vertical frontal and posterior walls, so that confines a substantially parallelepiped volume for collecting ballast means.
Document EP 1865111 A1 discloses a pedestrian or traffic barrier that comprises a panel curved in opposing edge regions each one of which having an engagement foot on the pavement whereas another foot extends obliquely from an opposite face of panel. Said barrier presents a plurality of crossing openings in the central and lateral regions, and does not confine a collection space for ballast means.
Document U.S. Pat. No. 5,993,103 discloses a control barrier with one or two support legs arranged on the lateral face so that can be rotated between a closed position where they are clapped down, and an open position where they form a “U” when seen in top view, thereby providing a stable standing placement configuration.
There is, therefore, the need for a traffic signalling and barrier system that comprises modules presenting a smaller volume per linear meter of barrier extension, and that provides a simpler handling of said system.
The objective of the present invention is to provide a traffic signalling and barrier system, for example roadway traffic, comprising a plurality of modules adapted so that can contain a ballast means and that can be successively laterally engaged with each other, and wherein each module presents a smaller volume per linear metre of extension of barrier, simultaneously providing structural stability, and a more efficient handling.
The objective above is solved according to the present invention by means of a traffic signalling system according to claim 1.
In particular, said objective is solved by means of a system whereby each module presents a central region with a cross-section that when seen in side view, presents a different shape and a different dimension than the cross-section of the lateral regions when seen in side view.
It is preferred when each module presents a central part that develops in a first direction and two lateral parts that develop as a continuation of each one of the lateral portions of said central region, in a second direction, backwards along a shape angle of acute shape.
It is particularly preferred when said angle is of at least 30° and at most 70° with relation to said first direction, so that said module presents a general shape of “U” type when seen in top view.
It is preferred when said modules present said central and lateral parts provided as a single piece and confining a single interior space adapted for collecting a ballast means.
It is preferred when said modules present a total extension in a barrier alignment direction, of at least 1 m and at most 1.5 m, preferentially an extension of 1.2 m, so that best occupy the space provided by a standard pallet.
It is preferred when said modules present a height of at least 50 cm, preferentially at most 1.5 m, preferentially at most 1.0 m.
A related objective of the present invention is that of providing a more ergonomic process of installation of a traffic signalling and barrier system.
The aforementioned objective is solved according to the present invention by means of a process according to claim 14.
