Abstract
Description
- The present invention relates to security systems; in particular, to security systems that impede intrusion to a particular restricted area.
- The invention has been devised particularly, although not necessarily solely, in relation to a multi-layered security system to prevent movement and access to a particular area and in particular to modular security systems.
- The following discussion of the background art is intended to facilitate an understanding of the present invention only. The discussion is not an acknowledgement or admission that any of the material referred to is or was part of the common general knowledge as at the priority date of the application.
- Impeding access into restricted areas as well as crowd control is becoming not only popular but a necessity due to security concerns in places where it is expected that a relative large crowd will be gathering to enjoy outdoors a particular entertainment activity (such as a concert) or political rallies. These security systems are typically defined by fencing systems adapted to be assembled for their use at a particular event and disassembled once the event has finished. Fencing systems provide a single layer of defense permitting people to climb the fence or ram against the fence so as to push the fence over due to the little or no strength of these types of fencing systems. Thus, a fence system is no longer an effective security systems for providing security to a multitude of people assembled in a particular area.
- Further, particular security systems have been installed in the cities due to the ongoing security threat of terrorist attacks that may be conducted in public places such as footpaths or pedestrian malls of cities using, for example, vehicles as weapons by driving the vehicles on footpaths or pedestrian malls and into the crowd. However, these current security systems not necessarily have the ability to stop these type of attacks.
- For example, currently, security systems have been installed in cities intended to provide security in the public places of the cities. These security systems are based on locating concrete bollards, planter boxes and/or monuments at the points of entry and exit of the footpaths and pedestrian malls to impede access of cars or trucks into these areas that typically are occupied with people. However, these concrete bollards, planter boxes and monuments are arranged in a spaced apart relationship and thus they only impede access of vehicles of a particular size such as cars and trucks; however, access into the restricted areas via relative small cars or motorcycles is still possible.
- Moreover, installation of a barrier using concrete bollards, planter boxes and/or monuments is expensive due to being relative heavy objects difficult to handle; thus, transportation to the particular public places requires large trucks; and once at site, heavy lifting equipment such as cranes is required for arranging the concrete bollards, planter boxes and monuments in the spaced apart arrangement to avoid intrusion of vehicles such as car or vehicles into public places bursting with pedestrians.

-
FIG. 1 shows a particular arrangement of asecurity system 10 in accordance with a first embodiment of the invention.FIG. 19 shows a particular arrangement of asecurity system 10 in accordance with a second embodiment of the invention. - The
system 10 is adapted to impede intruders on foot from accessing a restricted area bound at least partially by thesecurity system 10. In particular, thesecurity system 10 comprises a multitude ofbarriers 12 configured to hinder any intruders on foot from overcoming thesecurity system 10. Thesecurity system 10 is also adapted to impede any type of vehicles from accessing the restricted area in the event the vehicles may ram into the security system. - The
system 10 permits incorporation of a plurality ofsecurity devices 58 and/or 60 (seeFIGS. 20 and 21 ) with the intention to adjust the level of security that thesecurity system 10 can provide; this is particular useful in view that it is possible to, for example, upgrade or downgrade the level of security of thesecurity system 10 depending on the particular security threat at a particular location where thesecurity system 10 is installed. - As will be described below, the
security system 10 permits attachment at particular locations of thebarrier 12 ofsecurity devices 58 such asrollers 46 for impeding intruders from using the upper end of thepanels barrier 12; alternatively, thebarrier 12 may be fitted with razor blade wire assemblies at, for example, the upper end of thepanels - In an arrangement, the upper end of the panels 14 (and panel 16) are adapted to releasably receive the
security devices 58 permitting, as mentioned before, upgrading or downgrading the level of security of thebarrier 12. For example, if thesecurity system 10 is to be used for controlling attendees of outdoor music festivals, therollers 46 may be used for impeding the attendees to use the upper end of thepanels 14 as support to climb thebarrier 12 with the intention to access the festival. - Alternatively, razor blade wire assemblies may be installed onto the upper end of the panels 14 (and panel 16) in situations where greater security threats exist when compared to the security threats posted by the attendees of outdoor music festivals.
- Further, the
security system 12 may incorporatesecurity devices 60 that impede, for example, vehicles from ramming against thebarrier 12 of thesecurity system 10. As will be described below, vehicles barriers such as spikes barriers or modular bollards such as bollards adapted to be selectively displaced between an operative condition and a retracted condition may be part of thesecurity system 10. - The fact that the
security system 10 comprises a multitude ofbarriers 12, is particularly advantageous because it permits thesecurity system 10 to provide multiple layers of defense by usingsecurity devices - The
system 10 shown inFIG. 1 comprises a multitude ofbarriers 12 located in a spaced arrangement with respect to each other. In the arrangement shown inFIG. 1 , there is afirst barrier 12 a and athird barrier 12 c spaced apart with respect to each other defining asecond barrier 12 b. Thebarrier barriers - In alternative arrangements, there may be provided additional layers of defense. For example, vehicle barriers 60 (such as spike barriers or modular bollards) may located in front of the
first barrier 12 a defining the attack side of thesecurity system 10. In the event of an attack by a vehicle, the spike barriers act as a first layer of defense puncturing the tyres of the vehicle prior or during the vehicle impacting thefirst barrier 12 a; the modular bollards can stop the vehicles. - Further, other additional layers of defense to be incorporated in the
security system 10 may be systems to impede personnel on foot to use the barriers as support for gaining access to the restricted area. As will be described later herein, thesystem 10 comprises layers of defense comprising anti-climb meshes as well as free-rollingrollers 46 impeding intruders on foot to climb anybarriers 12 of thesecurity system 10 by getting hold of any possible support structure being part of thesecurity system 10. Razor blade wire assemblies may also incorporated as an additional layer of defense. - Moreover, in accordance with the first and second embodiment of the invention,
security systems 10 comprises a plurality of components adapted to be transported to the particular areas that require protection such as areas where entertainment activities like outdoor concerts or rallies will be held. At site, the components may be assembled relatively fast for erection of thesecurity system 10. Once assembled, thesecurity system 10 provides a fully interconnected single structure that may be moved or tilted only with the help of heavy lifting equipment; thus, a multitude of individuals or one or more vehicles ramping against thesecurity system 10 will not be able to move or tilt thesecurity system 10. - As mentioned before, the particular arrangement of
security system 10 shown in theFIGS. 1 to 18 comprises afirst barrier 12 a and athird barrier 12 c spaced apart with respect to each other defining asecond barrier 12 b. - As shown in
FIG. 1 , each of thebarriers panels panels barriers -
FIG. 2 shows the front of thepanel 14 a of thefirst barrier 12 a. Thepanels 14 are typically located at the attack side of thesecurity system 10. - Any
panel 14 comprises aframe 18 defined by two spaced part posts 20 and three breams 22 extending between theposts 20 for joining theposts 20 together. The three beams 22 (also referred as noggins) are arranged in a spaced apart arrangement with respect to each other defining to neighboring voids 26 a and 26 b in theframe 18. - Further, the
frame 18 is covered withanti-climb mesh 26 so as to define a surface adapted to hinder intruders on foot from climbing thepanel 14 with the objective of overcoming thebarrier 12 a. (For illustration purposesFIG. 2 shows only particular portions of theframe 28 covered withanti-climb mesh 26; however, themesh 26 covers theentire frame 18 of the panel 14). Themesh 26 is attached to the outer face of thepanel 14—the outer face is the face that defines the attack side of thesecurity system 10. The attack side of the security system is the side where it is expected that the intruders will impact first. -
FIG. 4 shows thefront side panel 16 a of thethird barrier 12 c. Thepanels 16 are typically located behind afirst barrier 12 a. Thisthird barrier 12 c acts as an additional layer of defense. In alternative arrangements, more than twobarriers 12 may be arranged in a tandem and spaced apart relationship. - The
panel 16 comprises aframe 18 defined by twoposts 20 spaced apart with respect to each other, and two beams 22 extending between theposts 20 for joining thepost 20 together. The two beams 22 are arranged in a spaced apart arrangement with respect to each other defining onevoid 26 within theframe 18 - Further, the
frame 18 is covered withmesh 28 defining a fence-like structure impeding access to the restricted area. (For illustration purposes,FIG. 4 shows only particular portions of theframe 28 covered withmesh 28; however, themesh 28 covers theentire frame 18 of the panel 16). - In a particular arrangement, the
mesh 28 of thepanels 16 may also comprise anti-climb mesh. The inner face (the face facing thefirst barrier 12 a) comprises themesh 28. - As mentioned before, the
panels 14 are arranged sided by side defining thebarrier 12 a; and, thepanels 16 are arranged side by side defining thebarrier 12 c. Thebarriers barriers second barrier 12 b located between the first andthird barriers second barrier 12 b defines apassage 13 that, as will be explained below, permits security officers to patrol thesecurity systems 10. - As shown in
FIG. 1 , the link bars 30 are adapted to attach (1) pairs ofpanels 14 that are adjacent each other, (2) pairs ofpanels 16 that are adjacent each other and (3) pairs ofpanels - Attachment of the
panels posts 20 of thepanels end 32 a of thelink bar 30 attaches the lower end ofposts 20 of neighboringpanels 14 and anotherend 32 b of thelink bar 30 attaches the lower end ofposts 20 of neighboringpanels 16. The ends 32 a and 32 b due to being spaced apart permit arranging thepanels passage 13 as is shown onFIGS. 9 and 14 . -
FIGS. 6 to 8 show a particular arrangement of thelink bar 30. - As shown in
FIG. 6 , thelink bar 30 comprises thefirst end 32 a and thesecond end 32 b and that are spaced apart with respect to each other via abar 34. Thebar 34 permits arranging thepanels - The
link bar 30 is adapted to be secured to the terrain on which thesecurity system 10 rests. For this, each end 32 comprisesopenings 31 to permitstakes 33 to traverse the ends 32 and penetrate the ground. The use ofstakes 33 is particularly useful when using thesecurity system 10 on surfaces comprising grass. - The
link bar 30 also comprises a pair ofplates 35 extending upwardly from thebar 34 of thelink bar 30 and spaced apart with respect to each other. Theplate 35 comprisesopenings 37 arranged in a spaced apart relationship with respect to each other. As will be described later with reference toFIG. 9 , theplates 35 permits receiving between them the lower end of abrace member 38. - Further, in one arrangement, the
bar 34 comprises one or more W bars 39 as shown inFIG. 8 . The W bars 39 comprise flexible steel to allow adjusting thelink bar 30 to any irregularities present on the ground. The W bars also remove the trip hazard when security officers are patrolling thepassage 13. - Moreover, each end 32 comprises
spigots 36 extending upwardly for receiving the lower ends of thepost 20. Each end 32 comprises two neighboringspigots 36 that permit releasably attaching the lower ends of theposts 20 of thepanels 14 adjacent to each other as well as of thepanels 16 adjacent to each other to define, respectively, thebarriers - The joint of the lower ends of the
posts 20 with thespigots 36 is adapted to permit pivotal movement of the posts around thepin 36. As will be described later, this pivotal movement permits varying the trajectory of thesecurity system 10 so as to for example define asecurity system 10 having a S-shaped configuration as shown inFIG. 1 . - Further, the upper ends of the
posts 20 of neighboringpanels FIGS. 10 and 11 a and 11 b, attachment occurs via ajoiner 42 comprising neighboring spigots 44 for insertion into the upper ends of thepoles 20. Thesejoiners 42 are also adapted to permit releasable attachment and pivotal movement of thepanels posts 20 and thepin 36 of thelink bar 30. - Moreover, the link bars 30 may also be used as an additional defense layer. For example, as shown in
FIG. 1 , there are twolink bars link bar 30. - Referring now to
FIG. 9 ,FIG. 9 shows a cross section of thesecurity system 10 along the line 9-9′ shown inFIG. 1 . - As mentioned before the
barrier 12 a in the particular arrangement shown inFIG. 1 defines the attack side of the security system 10 a. The attack side is the side of thesecurity system 10 that receives the initial assaults. Thus, thisparticular barrier 12 a requires reinforcement means so as to absorb as much energy as possible from the intruder's impact during the initial assault. By doing this, the intruder will be slowed down and most probably stopped at any subsequent layer of defense—for example: the passage 13 (thesecond layer 12 b—also referred as thesecond barrier 12 b) or thethird layer 12 c (also referred as thethird barrier 12 c). - As shown in
FIG. 9 , eachpanel 12 of thebarrier 12 a comprises abrace member 38 to provide additional reinforcement to thebarrier 12 a against impact. In a particular arrangement, there is abrace member 38 for eachpost 20 of each panel 4 of thebarrier 12 a. - The
brace 38 as shown inFIGS. 9 and 17 comprises arod 40 extending diagonally from a particular location (such as an upper location) of thepost 20 to a particular location at thebar 34 of thelink bar 30. The angle of inclination of therod 40 may for example depend on the particular uses that thesecurity system 10 will be given. The angle of inclination of thebrace 38 may be adjusted by attaching the lower end of therod 40 toparticular openings 37 of theplates 35. The upper end of the rod comprises alink 41 permitting attachment of thebrace member 38 to thepost 20 of thepanel 14. Thelink 41 is adapted to pivotally attach the upper end of thebrace member 38 so as to permit varying the angle of inclination of thebrace member 38. - Moreover, it was mentioned before that the
security system 10 in accordance with the first embodiment of the invention comprise means to impede intruders from gaining support from parts of thesecurity system 10 while trying to overcome the plurality of layers of defense. - In a particular arrangement, the security system may comprise free-rolling rollers impeding the intruders on foot to overcome the
barrier 12 a by getting hold of the upper end of thepanels 12 in case the intruders successfully were able to climb thepanel 12. -
FIG. 10 shows the front section of thebarrier 12 a comprising aroller arrangement 46 attached to the upper end of thepanels 14. - The
roller arrangement 46 comprises a plurality ofcylinders 48 arranged side by side on thepanels 14. In particular, each panel comprises a pair of rollers 48 a and 48 b. Therollers 48 are rotatably attached to support members attached to the upper end of thepanels 14. - The
rollers 48 are attached in a vertical manner on the upper end of thepanels 14. There is a gap of 10 mm between each roller and the upper end of thepanels 14 to remove a gripping joint. This arrangement allows for strength to the roller apparatus and additional height to thepanel 14. - In a particular arrangement, there may be provided a mesh portion over which the
rollers 48 will be located. This mesh portion impedes an intruder gaining access to therollers 48 or the inner side of thepanels 12 and thus, adding a further layer of defense. - Furthermore, the
panels 14 are adapted to be attached to each other to follow a particular trajectory depending on the particular area that thesecurity system 10 will provide protection to. - As shown in
FIG. 1 , thebarriers barriers posts 20 of neighboring panels 14 (or 16). As mentioned before, (1) the lower end of theposts 20 of the neighboring panels 14 (or neighboring panels 16) are pivotally attached to thespigots 36 of thelink bar 30, and (2) the upper ends of thepost 20 of the neighboring panels 14 (or neighboring panels 16) are joined together viajoiners 42 adapted to permit pivotal movement of the neighboring panels 14 (or neighboring panels 16). - The pivotal movement of the
panels barriers barriers FIGS. 1, 12 and 13 a change of direction by orienting the panels 14 (or 16) at angles other than 180°. - Referring now to
FIGS. 14 to 16 ,FIGS. 14 to 16 show particular views of an alternative arrangement of thesecurity system 10 according to the first embodiment of the invention. Thesecurity system 10 according to this alternative arrangement comprises features that are similar to thesecurity system 10 according to the first arrangement ofbarriers FIGS. 1 to 13 and similar reference numerals are used to identify similar parts. - The
security system 10 in accordance with the alternative arrangement comprises alink bar 30 adapted to account for any irregularities of the terrain on which thesecurity system 10 is mounted; for this thelink bar 30 comprises abar 34 that is elevated when compared to thebar 34 of thelink bar 30 of the first arrangement of thesecurity system 10 described earlier and shown inFIG. 6 . - As shown in
FIGS. 14 and 15 , the ends 32 of thelink bar 34 comprise plates 52 extending from the ends 32 upwardly for receiving thelink bar 34. In this manner, thebar 34 of thelink bar 30 is spaced apart a particular distance from theground 37 on which thesecurity system 10 rests defining aclearance 35—seeFIG. 15 . This particular arrangement oflink bar 30 accounts for any irregularities (such as rocks protruding upwardly from the ground 37) due to thepresence clearance 35 between (a) theground 37 on which thelink bar 30 rests and (b) thebar 34. To include one or more of these particular arrangements oflink bar 30 in the security system is particular useful for use when thesecurity system 10 is installed on irregular terrain. - There may be provided a
mat 54 for covering thebar 34 shown inFIG. 14 . Themat 54 provides a flat surface with the objective of reducing the trip hazard created by theelevated bar 34 of thelink bar 30 described in the earlier paragraph. Also, themat 34, due to resting on thelink bar 30, can enhance the stability of thesecurity system 10; this is particularly true in the particular circumstances where the mat 56 is relative heavy. - Further, as also shown in
FIG. 14 , there is provided anupper beam 54 joining the upper ends of thepanels barriers upper beams 54 arranged in a spaced apart relationship with respect to each other alongsecurity system 10. - This particular arrangement of
upper beams 54 keeps together thebarriers - Further, in a particular arrangement of the previously described
security systems 10, thefirst barrier 12 a may be tilted forward a particular angle as is shown inFIG. 16 in connection with the alternative arrangement of thesecurity system 10. Tilting thepanel 14 of thebarrier 12 a increases the difficulty for an intruder to climb thebarrier 12. - Further, other alternative arrangements of the
security system 10 may comprise arches located at the upper end of, for example, thepanels 14. The arches are arranged in such a manner that one side of the arch (the haunch of the arch) is attached to the upper end of thepanels panel security system 10 is mounted. The presence of the arch increases the difficulty for an intruder to climb thebarriers 12 due to having to overcome the arch one reaching the upper end of thepanels - Further, other alternative arrangements of the
security system 10 may include, instead or in conjunction with the anti-climb meshes 26, an assembly of wires extending between theposts 20 of thepanels - The pulley comprises portions of the wire wound around the axis of the pulley. This arrangement impedes the intruders from gaining support when trying to start climbing the
panels panel - In operation, once the
security system 10 has been installed, thesecurity system 10 impedes intruders on foot or in vehicles to enter the restricted areas bound by thesecurity system 10. - As mentioned before, the
system 10 comprises a multitude of layers of defense with the intention that each attack is gradually mitigated as the intruders overcome each of the defense layers; and, as the intrusion progresses, the resources of the intruders are reduced and consumed; this results in that intrusion is slowed down until it is halted or turned back. - In particular, the
security system 10 shown inFIG. 1 comprises a plurality ofbarriers 12 that provide layers of defense for gradually reducing the action of intruders trying to gain access to the restricted area bound by thesecurity system 12. For example, thesecurity system 10 shown in figures comprises afirst barrier 12 a defining one or more layers of defense with intention to mitigate as much as possible the action of the intruders. In the circumstances where the intruder is able to overcome thefirst barrier 12 a by for example successfully climbing thepanels 14, the intruder enters into thepassage 13. Thepassage 13 acts as another layer of defense allowing the security officers to patrol thesecurity system 10 by walking along thepassage 13. This allows controlling any intruder that has overcome thefirst barrier 12 a. Authorised access to thepassage 13 is accomplished by the use of secured entrances such as doors 50 (seeFIG. 18 ) placed at regular intervals for permitting entrance of security officers into thepassage 13 as well for removing any intruder that may have been able to enter thepassage 13. - The
third barrier 12 c is adapted to impede the intruder from exiting thepassage 13 by climbing thebarrier 12 c defined by thepanels 16—for example, thebarrier 12 c may also comprise layers of defense such as anti-climb mesh or arches. - Thus, the
security system 10 in accordance with the first embodiment of the invention provides a multi-layered barrier to impede access of intruders on foot or using motorised vehicles into restricted areas bounded by thesecurity system 10. -
FIGS. 19 to 21 show a particular arrangement of asecurity system 10 according to a second embodiment of the invention. Thesecurity system 10 according to the second embodiment is similar to thesecurity system 10 according to the first embodiment and similar reference numerals are used to identify similar parts. - The
system 10 in accordance with the second embodiment of the invention comprises abarrier 12 configured to hinder any intruders on foot from overcoming thesecurity system 10. Thesecurity system 10 is also adapted to impede any type of vehicles from accessing the restricted area in the event the vehicles may ram into the security system. - The
security system 10 according to a second embodiment of the invention comprises one ormore panels 14 to define thebarrier 12. - In the particular arrangement shown in
FIGS. 19 to 21 , eachpanel 14 comprises apanel 14 as described with reference to the first embodiment of the invention comprising aframe 18 covered withanti-climb mesh 26 for impeding intruders from climbing thepanels 14 to try to overcome thebarrier 12. - In the present arrangement, the
panels 14 are attached to each other to define thebarrier 12. In particular, adjacent panels 14 (such aspanels FIG. 19 ) are releasably and pivotally attached to each other via one of theends 32 b of the link bars 30. The other ends 32 a, located at the other end of thebars 34 of the link bars 30, are spaced apart from theends 32 b. - As was described with reference to the first embodiment of the invention, each
link bar 30 is adapted to be secured to the terrain on which thesecurity system 10 rests. For this, each end 32 of thelink bar 30 comprisesopenings 31 to permitstakes 33 to traverse the ends 32 and penetrate the ground—seeFIGS. 20 and 21 . The use ofstakes 33 is particularly useful when using thesecurity system 10 on surfaces comprising grass. - In alternative arrangements, the link bars 30 may be attached to the ground by bracing them with concrete weighted footings.
- Further, the link bars 30 rest on the ground on which the barrier is installed. The fact that each
link bar 30 comprises abar 34 extending away from thebarrier 12 provides support to thebarrier 12 impeding tilting of thebarrier 12 by intruders pushing against thepanels 14 defining the attack side of thebarrier 12. The fact that eachlink bar 30 is attached to ground (for example, via stakes 33) aids in impeding intruders from moving and tilting thebarrier 12.Spike barriers 60 may be located on the roof structure. - The particular arrangement of
barrier 12 shown inFIG. 19 comprises the first arrangement oflink bar 30 described with reference toFIG. 9 related to the first embodiment of the invention. Alternative arrangements of thebarrier 12 according to a second embodiment of the invention may comprise the second arrangement oflink bar 30 described with reference toFIG. 14 related to the first embodiment of the invention. - The
barrier 12 according to the second embodiment of the invention is particular useful in particular situations where not enough space is available for installing themultilayered barrier 12 in accordance with the first embodiment of the invention; for example, thebarrier 12 according to the second embodiment of the invention is particularly advantageous for surrounding constructions site to impede access to the site of non-authorised personnel or intruders. - Modifications and variations as would be apparent to a skilled addressee are deemed to be within the scope of the present invention.
- Further, it should be appreciated that the scope of the invention is not limited to the scope of the embodiments disclosed. For example, in alternative arrangement, the
security system 10 may comprise a roof type structure for protecting thesecond barrier 12 b (the passage 13). The roof structure may be supported on thebeams 54 that join the upper end ofbarriers - Throughout this specification, unless the context requires otherwise, the word “comprise” or variations such as “comprises” or “comprising”, will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers.
