Definitions

  • the present invention belongs to the sector of movable barrier elements, in particular to the sector of those barrier elements which are used on a temporary basis to regulate, convey, or completely prevent the passage of persons; for example, in the case of events that draw a large audience.
  • scopes of the present invention are a device and a method for modifying barrier elements of known types, so as to zero, or at least reduce, their dangerousness in case of fall.
  • Movable barrier elements formed of a vertical parapet featuring a substantially rectangular shape, resting on at least two bases, each of which is shaped as an overturned "V", are of general use for a long time in order to regulate the passage of persons in otherwise open areas.
  • Every base comprises two inclined feet, which project transversally and whose ends touch the ground; a vertical axis hole is present in the central portion of the base of these barrier elements, suitable for slidingly receiving internally thereto a respective vertical pin which protrudes below from the vertical parapet.
  • this pin is nothing but an extension of the vertical side edge of the parapet; usually it is a tubular element featuring a circular cross section, less often it features a polygonal cross section.
  • the parapet of these barrier elements is usually made from a metal, with a tubular perimetric edge and several elements internal to the edge, the purpose of the latter being that of rendering the parapet impervious to persons; typically there are a plurality of vertical elements internally to the rectangular perimetric edge, their ends being integrally connected to the upper horizontal edge and to the lower horizontal edge respectively.
  • connection of the pin internally to the hole of the stand is a reversible one and makes it possible to easily remove the bases from the parapets, for example in order to make transportation and storage of the barrier elements easier.
  • the barrier elements of this type include longitudinal connection means which reversibly join them to each other, in order to form a continuous line of barrier elements suitable for delimiting longer sections of the longitudinal development of a single barrier element; usually the means used to longitudinally connect the barrier elements are located in correspondence with the side edges of the vertical parapets.
  • the ends of the tubular elements that form its two feet are cut obliquely with respect to their longitudinal axis in order to improve the stability of each individual base.
  • the feet are inclined with respect to the ground and their ends are cut according to a horizontal plane, parallel to the ground; it follows that the ends of the base are pointed, with an angled cut, a so-called salami slice or flute beak cut.
  • the barrier element should the barrier element fall down, the end of the foot of the base is anyway facing upwards and, even though it does not end in a sharp point, it is nonetheless a point that is harmful, should anybody fall thereon.
  • U.S. patent application US2006/231820 describes a barrier element with bases capable of partially rotating about the pin; every base comprises a tubular central body, from which two feet project.
  • the tubular central body enters the inside of the pin of the barrier element which it is coupled with, thanks to the a bolt passing through a slot present in the central body itself, whose ends are shaped in such a way as to prevent the through bolt from rotating once the latter reaches the end of its rotation.
  • the cross section of said slots is greater at the ends, so that the bolt goes down and reaches a lower position, thus causing a corresponding vertical displacement of the pin of the barrier element, hence the barrier element shall be lifted first in order for it to rotate in the reverse sense.
  • the base for barrier elements and the method according to the present invention aim at providing a system for rendering the known barrier elements of the described type harmless, should they be brought down to the ground; in particular, an object of the present invention is to automatically prevent the presence of harmful points facing upwards in the case of an overturning, which might cause very severe injuries to those people who might fall thereon.
  • Another object of the present invention is to provide a base that can be installed under the parapets of barrier elements already in use, and a method for performing a simple replacement of a traditional base with a base that is capable of changing from an open working configuration to a closed idle configuration, thanks to the movement of a very limited number of component parts and simultaneously makes the barrier element little bulky during transportation and storage.
  • a no less important object of the present invention is to provide a base that allows for a barrier element to be safely brought down under the action of thrusts exerted on any of the side of the parapet.
  • a further object of the barrier element according to the present invention is to provide a method that allows to quickly modify barrier elements of known types, so as to make them harmless in case of overturning.
  • a base comprising a central body (1), from which at least two feet (2, 3) protrude, and comprising internally thereto a vertical axis cavity (11), shaped in such a way as to slidingly receive internally thereto a corresponding vertical pin (B), of a type projecting below from the parapet of barrier elements of known types (A) ;
  • the base for movable barrier elements according to the present invention comprises rotational coupling means suitable for driving the teeth (2, 3) into rotation between a first projecting working position and a second flattened idle position, which takes place whenever the barrier element falls down to the ground.
  • the movable barrier element of a known type after being modified according to the present teaching, will not present any longer sharp ends of feet facing upwards, which are very harmful for a person who falls thereon, but the ends of the teeth will lay in a horizontal plane parallel to the ground, without creating harmful situations and reducing space occupation as much as possible.
  • the scope of protection of the present invention also comprises a method that allows to transform barrier elements of known types into security barrier elements, by removing their base of a traditional type with a base as described in this document.
  • the central body (1) of the base defines a cylindrical cavity (11), internally to which the pin (B) is slidingly engaged according to a vertical axis and retains the capability of rotating about said axis.
  • the base In the first projecting working position, the base is placed in such a way that the feet (2, 3) are transversal with respect to the vertical plane of the parapet, so that, should the barrier element fall down, it will be the weight of the latter to provoke a rotation of the base until the feet reach the second flattened idle position and will lay on the ground, without creating any elements that are harmful for those who fall down to the ground above the fallen down barrier element, because of the crush.
  • Reversible retention means are adopted to be able to rise the barrier element without making the bases disconnect from the parapet (A), which prevent the base from slipping off, while allowing a partial reciprocal rotation thereof.
  • Figures 1 , 3 , 4 , 5, and 6 show a configuration wherein said anti-slip-off means comprise a bolt, not shown in the figures, the screw of which crosses both the pin (B) of the barrier element and two circumferential slots (4) defined on the central body (1) of the base for one quarter of the circumference and diametrically opposed to each other, so as to allow for a partial rotation of the base about the pin (B), but not its slipping off.
  • said anti-slip-off means comprise a bolt, not shown in the figures, the screw of which crosses both the pin (B) of the barrier element and two circumferential slots (4) defined on the central body (1) of the base for one quarter of the circumference and diametrically opposed to each other, so as to allow for a partial rotation of the base about the pin (B), but not its slipping off.
  • the slots (4) are defined for an angle less than one quarter of the circumference, for example for an angle ranging from one quarter to one sixth; the latter configuration is shown in figure 6 and facilitates the rotation of the base should the barrier element fall down, thus preventing the risk of stopping dead.
  • the pins (B) of the parapet (A) are of a polygonal cross section type, it is necessary to adopt a second embodiment wherein the vertical cavity (11) defined internally to the central body (1) of the base also features a polygonal internal cross section, so as to receive the pin (B) internally thereto, but not such as to allow the latter to rotate about its own vertical longitudinal axis.
  • the two feet (2, 3) are hinged to the central body (1), according to a horizontal longitudinal axis, and rotate in a vertical plane orthogonal to the vertical plane defined by the parapet (A); however, further configurations are possible which remain within the scope of the same inventive concept, even though the feet close by rotating about non horizontal axes.
  • the rotation of the feet between the two extreme positions takes place independently and is completely free; however, other embodiments are possible wherein, in order to make the feet change from the working position to the idle position, it is necessary to overcome the resistance offered by appropriate retention means such as, for example, one or more magnets.
  • perforations are provided in the central body (1) of the base to receive a screw, the function of which is to prevent the pin protruding below from the parapet from accidentally sliding and to prevent it from slipping off the cavity defined in the central body (1) .
  • the weight of the parapet (A) can be discharged onto the bases alternatively, thanks to the presence of appropriate shoulders, or ledges, as shown in figures 1, 2 , and 3 , or thanks to said retention means which, besides performing the function of preventing the base from slipping off, should the barrier element be raised, are also used to transfer the load of the parapet to the bases.
