Description

Fencing mesh assembly for a fence.

The present invention relates to a fencing mesh assembly for a fence, in particular a fencing mesh assembly that is in particular intended to be used to prevent people to intrude a certain area. The present invention also relates to a fence comprising such a fencing mesh assembly, and to a method for arranging a fencing mesh assembly.

To prevent people or animals to intrude a certain area, a fencing mesh can be provided that needs to be strong and firm. To this end, a fencing mesh usually comprises sets of wires that intersect, wherein at locations where the wires intersect the wires are mutually connected. Such a fencing mesh can be used in a wire mesh security fence.

Strong and firm fencing meshes are known that even prevent projectiles to intrude in a certain area. For example EP S149260 B1 describes a fencing mesh having a first set of wires which are arranged essentially parallel with respect to each other and a second set of wires which are arranged essentially parallel with respect to each other and intersect the first set of wires, wherein the wires of the first set of wires are connected to the wires of the second set of wires at locations where they intersect. The wires of the first set of wires are connected to the wires of the second set of wires by welding them to one another, in order to be connected to each other in a solid way.

A fencing mesh as described in EP 3149260 B1 has the disadvantage that it can be damaged or destroyed by an intruder, for example by an intruder using a grinding tool. In this way, the intruder can make an opening in the fencing mesh and enter along this opening through the fencing mesh.

It is an object of the invention to provide a fencing mesh assembly that is strong and firm and that is effective against intruders, in particular that can withstand against an attack by an intruder using a grinding tool during several minutes, for example during at least five minutes as stipulated in the ASTM F2781 norm for aggressive testing.

The object of the invention is achieved by the features of claim 1, the features of claim 18, the features of claim 21, and the features of the dependent claims.

According to a first aspect of the invention, a fencing mesh assembly is provided, comprising a front mesh panel comprising solid connected intersecting wires, a rear mesh panel comprising solid connected intersecting wires, and several cross mesh panels comprising solid connected intersecting wires, wherein the cross mesh panels are arranged between the front mesh panel and the rear mesh panel, are connected to the front mesh panel and to the rear mesh panel, and are arranged distributed over the front mesh panel and over the rear mesh panel, in particular distributed over the extent of the front mesh panel and over the extent of the rear mesh panel. In installed state of this fencing mesh assembly the cross mesh panels are arranged in a direction cross to both the front mesh panel and the rear mesh panel, adjacent cross mesh panels are arranged spaced apart over a distance from each other, and the front mesh panel and the rear mesh panel are arranged spaced apart over a distance from each other. More in particular, the cross mesh panels are arranged with their panel surface in a direction cross to both the front mesh panel and the rear mesh panel, adjacent cross mesh panels are arranged with their panel surface spaced apart over a distance from each other, and the front mesh panel and the rear mesh panel are with their panel surface arranged spaced apart from each other.

In the context of the application, the front mesh panel can also be named as first mesh panel, or front fencing mesh or front fencing mesh panel, while the rear mesh panel can also be named as second mesh panel, or rear fencing mesh or rear fencing mesh panel. A cross mesh panel can also be named as third mesh panel, or cross fencing mesh or cross fencing mesh panel. As the cross mesh panels are arranged between the front mesh panel and the rear mesh panel, the cross mesh panels can also be named as intermediate mesh panels. It is clear that the terms "front mesh panel" and "rear mesh panel" are only used to indicate that there are two different mesh panels. The "front mesh panel" is usually the mesh panel from where an intruder intends to enter. In the context of the application, a mesh panel comprises solid connected intersecting wires defining a panel surface.

With this arrangement a strong and firm fencing mesh assembly is obtained that can withstand an attack with a grinding tool during several minutes. Therefore, this fencing mesh assembly is particularly suitable to be used as an anti-grind fencing mesh assembly for an anti-grind fence.

Due to the several cross mesh panels, forces acting upon the front mesh panel, can be guided via the cross mesh panels to the rear mesh panel, so that the fencing mesh assembly can easily withstand forces acting upon the front mesh panel by an intruder.

Due to the fact that several cross mesh panels are distributed over the panel surface of the front mesh panel and over the panel surface of the rear mesh panel, the front mesh panel and the rear mesh panel are almost over their whole extent, in other words over almost their entire panel surface, connected to one another. Due to these cross mesh panels, an intruder cannot find any place along the panel surface of the front mesh panel where it is possible to enter easily using a grinding tool.

In a preferred embodiment, in installed state the several cross mesh panels of the fencing mesh assembly are arranged consecutive above one another. In this embodiment, the cross mesh panels can be arranged with their panel surface in a horizontal direction, wherein the panel surfaces of consecutive above one another arranged mesh panels are spaced apart over a distance from each other when used in a fence. Such a fencing mesh assembly also offers the advantage that the fencing mesh assembly can easily be brought in a compact state for transport and storage, and in an installed state. Such a fencing mesh assembly also provides a substantial rigidity against bending forces exerted on the fencing mesh assembly when the fencing mesh assembly is used in fence.

In a preferred embodiment, in installed state the front mesh panel and the rear mesh panel are arranged spaced apart over a distance in a range between 200mm and 450mm, in particularly a distance of approximately 300mm from each other. Due to a distance in such an order of magnitude the fencing mesh assembly forms an anti-grind fencing assembly, that can be used in an anti-grind wire mesh security fence. The minimum distance over which the front mesh panel and the rear mesh panel are to be arranged spaced apart should at least be larger than the distance over which a standard grinding tool acting from the front mesh panel can reach the rear mesh panel, and preferably also larger than the distance over which a standard grinding tool acting from the front mesh panel can reach, or can grind up to, the rear part of the respective cross mesh panel situated near the rear mesh panel. A distance in a range between 200mm and 450mm is certainly sufficient for avoiding that an intruder can grind the front mesh panel and the rear mesh panel in one time using a standard grinding tool.

Due to the fencing mesh assembly according to the invention, in particular due to the distance between the front mesh panel and the rear mesh panel, and also due to the presence of several cross mesh panels, an intruder cannot grind the front mesh panel and the rear mesh panel in one time using a standard grinding tool, such as a standard grinding tool with a grinding disc having a diameter of 125mm or 230mm. In other words, an intruder cannot reach the rear mesh panel with a standard grinding tool from the front mesh panel. Further, an intruder cannot find any place along the panel surface of any mesh panel where it is possible to pass easily using a grinding tool. Further, the fencing mess assembly is protected on the side of the front mesh panel as well as on the side of the rear mesh panel, so that there is not attack side or safe side, as both sides of the fencing mesh assembly are protected.

In a preferred embodiment, in installed state adjacent cross mesh panels are arranged spaced apart over a distance in a range between 250mm and 500mm, in particular over a distance of approximately 300mm from each other. Such a distance is certainly sufficient for avoiding that an intruder can grind an opening that is sufficient to allows the intruder to pass along the opening without the need to grind through or destroy at least one cross mesh panel as well. For example, for allowing an intruder to pass along an opening, an opening of approximately 600mm on 600mm, in particular two square feet as stipulated in the ASTM F2781 norm, is considered to be necessary. The distance over which the adjacent cross mesh panels are spaced apart is for example larger that the distance over which the front mesh panel and the rear mesh panel are spaced apart, so that the fencing mesh assembly can easily be brought in a compact state for transport and storage.

Preferably, in installed state the cross mesh panels are arranged in a direction substantially perpendicular to both the front mesh panel and the rear mesh panel. In other words, in installed state the cross mesh panels with their panel surface are arranged at an angle of substantially 90° to both the panel surface of the front mesh panel and the panel surface of the rear mesh panel. Preferably, in installed state adjacent cross mesh panels are arranged substantially in parallel to each other. Preferably, in installed state the front mesh panel and the rear mesh panel are arranged substantially in parallel to each other.

In a preferred embodiment, each cross mesh panel is hinged connected to the front mesh panel and each cross mesh panel is hinged connected to the rear mesh panel. To this end, each time a hinged connection is provided. In other words, the cross mesh panel is connected to the front mesh panel by an hinged connection, and the cross mesh panel is connected to the rear mesh panel by an hinged connection. Preferably a hinged connection is provided that allows that in installed state a cross mesh panel can vibrate with respect to the front mesh panel and/or to the rear mesh panel. Preferably, the hinged connection comprises a helical wire member. Hinged connections, also named pivotal connections, are preferably spiral connections comprising a helical wire member or coil. This allows that the mesh panels are connected hinged together, in particular are hinged connected to one another along hinge lines. Such a helical wire connection also allows that a sufficient play for such a vibration is present between a cross mesh panel and a respective front mesh panel or rear mesh panel. Such a play is also advantageous for being able to rotate easily the helical wire member or coil through the meshes in the mesh panels.

Further, an intruder is not only hindered by the cross mesh panels for reaching the rear mesh panel, but due to the use of a helical wire member for connecting the cross mesh panels, when using a grinding tool vibrations will arise at the cross mesh panel that hinder the grinding action and can damage the grinding tool. The fact that the cross mesh panels are not solidly fixed to the front mesh panel, neither to the rear mesh panel, offers the advantage that the cross mesh panels can be moved in installed state with respect to the front mesh panel and to the rear mesh panel, which movement can cause vibrations during an attack with a grinding tool, which vibrations also hinder the grinding action for grinding through of the cross mesh panel and can damage the grinding tool. This also offers the advantage that any one of the cross mesh panels is difficult to be destroyed.

A helical wire member connection is not only a simple and compact connection, but such a helical wire member connection can also withstand an attack with a grinding tool as long as one coil of the helical wire member is not destroyed. In other words, an intruder has to destroy the helical wire member over its whole length by a grinding tool. Due to this, a cross mesh panel can remain in place with respect to the rear mesh panel as long as not all coils near the front mesh panel are destroyed.

In a preferred embodiment, each cross mesh panel has an elongated rectangular shape defining a panel surface having large sides and short sides, wherein the assigned hinged connection is arranged along substantially the whole length of a large side of the cross mesh panel. This allows that the cross mesh panel remains substantially in place even when a part of the hinged connection is already destroyed by a grinding tool. The hinged connection can be designed as a helical wire member made in one piece that is arranged along the whole length of the large side of the cross mesh panel, or can be made by a number of helical wire members that are arranged next to one another to be arranged together along the whole length of a large side of the cross mesh panel.

In an embodiment, each cross mesh panel has an elongated rectangular shape defining a panel surface having large sides and short sides, wherein the large sides of the cross mesh panel are respectively connected to the front mesh panel or to the rear mesh panel. Preferably, the length of the large sides of the cross mesh panels is less than the width of the front mesh panel and is less than the width of the rear mesh panel. In this context, with the term "width" is meant a direction in the direction of the large sides of the cross mesh panel. This allows to arrange the fencing mesh assembly between posts for being incorporated in a fence, in particular to arrange the short sides of each cross mesh panel near a cross surface of a post, while a lateral end of the front mesh panel can reach over the front surface of the post, and a lateral end of the rear mesh panel can reach over the rear surface of the post. In this way, the post can be partly surround by the fencing mesh assembly. In installed state, the length of the short sides of the cross mesh panels almost equals the distance between the front mesh panel and the rear mesh panel. This allows to arrange the cross mesh panels intermediate between the front mesh panel and the rear mesh panel with respect to a post, or to sandwich the fencing mesh assembly between two posts.

In an embodiment, each cross mesh panel, and preferably also the front mesh panel and the rear mesh panel, are a mesh panel comprising a first set of wires which are arranged essentially parallel with respect to each other and a second set of wires which are arranged essentially parallel with respect to each other and intersect the first set of wires, wherein the wires of the first set of wires are connected to the wires of the second set of wires at locations where the intersecting wires intersect. In this embodiment, the wires of the first set of wires is arranged substantially perpendicular to the wires of the second set of wires at locations where the intersecting wires intersect. Preferably, the intersecting wires of the first set of wires and the second set of wires, that are solid connected to each other at locations where the intersecting wires intersect, are connected by welding. Due to this, a cross mesh panel is very strong and firm, and also prevent that projectiles can intrude through this cross mesh panel.

Preferably, the pattern of the wires of the front mesh panel, the rear mesh panel and each cross mesh panel is similar in design and/or in size. An embodiment wherein all mesh panels are of the same design and/or size offers the advantage that a same base mesh panel can be used for all three mesh panels, in particular a base mesh panel wherein the pattern of the wires is the same.

Preferably, the fencing mesh assembly comprises a front mesh panel comprising connected intersecting wires that are solid connected by welding, a rear mesh panel comprising connected intersecting wires that are solid connected by welding, and cross mesh panels comprising connected intersecting wires that are solid connected by welding. Such welded intersecting wires provide a strong and firm mesh panel.

According to a second aspect of the invention, a fence comprises a fencing mesh assembly according to the invention is provided. The application of a fencing mesh assembly according the invention in a fence offers the advantage that a relative large area can be protected in a simple way.

In a preferred embodiment, in installed state the several cross mesh panels of the fencing mesh assembly are arranged horizontally. When used in a fence by arranging the several cross mesh panels horizontally, the advantage is obtained that it remains possible to look through the fencing mesh assembly, in other words the visibility through the fencing mesh assembly is not impeded by the cross mesh panels. When arranging the several cross mesh panels horizontally and when arranging the fencing mesh assembly with its lateral sides between two posts, a further advantage is obtained that the fencing mesh assembly also provides a substantial rigidity against bending forces exerted on the fencing mesh assembly.

In an embodiment, the fence comprises posts and the fencing mesh assembly is attached between two posts. The fencing mesh assembly according to the invention is particularly suitable for the application in a fence and offers the advantage that such a fence can be used as an anti-grind fence. When coupling the fencing mesh assembly to posts also an sufficient rigidity of the fence assembly can be ensured.

Preferably, when used in a fence the panel surface of each of the cross mesh panels of the fencing mesh assembly is arranged horizontal.

According to a third aspect of the invention, a method is provided for arranging a fence assembly according to the invention such that in installed state cross mesh panels of the fencing mesh assembly can vibrate with respect to front mesh panel and/or to the rear mesh panel in installed state. Preferably, when used in a fence, the cross mesh panels are arranged horizontal.

The present invention will now be described in more detail by means of the following detailed description of a few preferred embodiments of a fencing mesh assembly and a fence according to the present invention. The aim of this description is solely to give illustrative examples and to indicate further advantages and particulars of the present invention, and can thus not be interpreted as a limitation of the field of application of the invention or of the rights defined in the claims.

In this detailed description, reference numerals are used to refer to the attached drawings, in which :

The fencing mesh assembly 10 as illustrated in Figs. 1 to 3 is shown in the installed state and comprises a front mesh panel 1 comprising a first set of wires 2 intersecting with a second set of wires 3, a rear mesh panel 4 comprising a first set of wires 5 intersecting with a second set of wires 6, and several cross mesh panels 7 comprising a first set of wires 8 intersecting with a second set of wires 9. The wires of each set of wires which are arranged essentially parallel with respect to each other. The wires of each first set of wires 2, 5, 8 and the wires of each second set of wires 3, 6, 9 are arranged substantially perpendicular with respect to each other and intersect. At each intersection of wires, wires of the first set of wires 2, 5, 8 are connected to the wires of the second set of wires 3, 6, 9. With the term 'wires' elongate elements or rod shaped elements are meant, for example a rod-shaped elements having a circular cross section or any other shaped cross sections. As can be seen in Fig. 1, both the front mesh panel 1 and the rear mesh panel 4 are shaped rectangular, and define a panel surface, in particular an almost planar panel surface.

The cross mesh panels 7 are arranged between the front mesh panel 1 and the rear mesh panel 4. Each cross mesh panel 7 is connected to the front mesh panel 1 and each cross mesh panel 7 is connected to the rear mesh panel 4. As best can be seen in Fig. 1, a number of ten consecutive arranged cross mesh panels 7 are arranged evenly distributed over almost the whole extent of the front mesh panel 1 and over almost the whole extent of the rear mesh panel 4, in other words over almost the entire panel surface of both the front mesh panel 1 and the rear mesh panel 4. In this example, to this end, all cross mesh panels 7 are arranged substantially in parallel to each other, and adjacent cross mesh panels 7 are arranged spaced apart over a distance from each other, in particular spaced apart over the same distance from each other. As shown in Fig. 1, the fencing mesh assembly 10 comprises ten cross mesh panels 7 distributed over the extent of the fencing mesh assembly 10.

Because each cross mesh panel 7 has a first set of wires 8 which are arranged essentially parallel with respect to each other and a second set of wires 9 which are arranged essentially parallel with respect to each other and intersect the first set of wires 8, wherein the wires of the first set of wires 8 are arranged substantially perpendicular to the wires of the second set of wires 9, wherein the wires of the first set of wires 8 are connected, for example are welded, to the wires of the second set of wires 9 at locations where the intersecting wires intersect, a strong and firm cross mesh panel 7 is present.

As base mesh panel for the front mesh panel 1, the rear mesh panel 4 and the cross mesh panels 7 is, for example, a mesh panel as disclosed in EP 3149260 B1 of the applicant. Of course, other strong and firm mesh panels are possible. Examples of such a mesh panel are amongst others the mesh panels Securifor, Securifor 2D, Securifor 3D and Securifor 4D of the applicant.

As illustrated in Fig. 3, each cross mesh panel 7 has an elongated rectangular shape defining a panel surface having large sides 15 and short sides 16, wherein one of the large sides 15 of the cross mesh panel 7 is intended to be connected to the front mesh panel 1 and the other one of the large sides 15 of the cross mesh panel 7 is intended to be connected to the rear mesh panel 4. In this embodiment, the length of the short side 16 is approximately 200 mm, while the length of the large side 15 is more than 2000mm, for example approximately 2200mm. Further, each cross mesh panel 7 has an almost planar panel surface. The large sides 15 of the cross mesh panel 7 are arranged along the width of the cross mesh panel 7. In this context, with the term "width" is meant the direction in the direction of the large sides 15 of the cross mesh panel 7, in particular the horizontal direction when used in a fence.

In installed state the cross mesh panels 7 are all arranged in a cross direction to, preferably substantially perpendicular to, both the front mesh panel 1 and the rear mesh panel 4. The adjacent cross mesh panels 7 are arranged spaced apart over a distance from each other. For example, adjacent cross mesh panels 7 are arranged at a distance of approximately 300mm from each other. The front mesh panel 1 and the rear mesh panel 7 are arranged spaced apart over a distance from each other, so that the distance between the front mesh panel 1 and the rear mesh panel 4 is determined by the length of the short sides 16 of the cross mesh panels 7. For example, the front mesh panel 1 and the rear mesh panel 4 are arranged substantially parallel to each other and at a distance of approximately 200mm from each other. In other words, the length of the short sides 16 of the cross mesh panels 7 almost equals the distance between the front mesh panel 1 and the rear mesh panel 4.

As best can be seen in Fig. 2, each cross mesh panel 7 is connected to the front mesh panel 1 by means of a hinged connection 11 and each cross mesh panel 7 is also connected to the rear mesh panel 4 by a hinged connection 12. The hinged connections 11, 12 are provided between meshes of the respective mesh panels. Both hinged connection 11, 12 are designed as a helical wire member. Such a hinged connection is particularly advantageous for causing vibrations during an attack with a grinding tool, in particular when the hinged connections 11, 12 are provided between the meshes of the respective mesh panels with an amount of play.

In this embodiment, the pattern of the wires of the front mesh panel 1, the pattern of the wires of the rear mesh panel 4 and the pattern of the wires of each cross mesh panels 7 is similar in design and/or in size.

As illustrated in Fig. 1, each hinged connecting 11, 12 is arranged along the width of the assigned cross mesh panel 7. Preferably, the length of the large sides of each cross mesh panel 7 is less than the width of the front mesh panel 1 and is less than the width of the rear mesh panel 4. As will be illustrated below, this is particularly advantageous for mounting the fencing mesh assembly 10 between posts. For example, the width of the front mesh panel 1 and the width of the rear mesh panel 4 is in both case approximately 2300mm, while the height of the front mesh panel 1 and the height of the rear mesh panel 4 is in both case approximately 3000mm. In this example, the large length 15 of the cross mesh panel 7 is almost 2200mm.

In the context of the application, any kind of mesh panel can be used for the front mesh panel 1 , the rear mesh panel 4 and the cross mesh panels 7 that is sufficiently strong and firm. It is however preferred to use mesh panels having metal wires that have a tensile strength in the order of magnitude from 300 MPa to more than 550 MPa, that have a diameter between approximately 3mm and 6mm, for example 4mm, and that are preferable made of steel. A mesh panel that is sufficiently strong and firm can for example have vertically arranged wires that are arranged at a distance between 30mm and 100mm, for example 76.2mm, and horizontally arranged wires that are arranged at a distance between 10mm and 50mm, for example 12.7mm. In this example the mesh size is 76.2mm x 12.7mm (height x width). Of course other dimensions and patterns of wires that offer a mesh panel that is sufficiently strong and firm are possible. The intersecting wires are solid connected in any appropriate way. Preferably, the intersecting wires are solid connected by a welded connection, which is a solid connection and is advantageous for providing strength.

The fencing mesh assembly 10 can be assembled or produced in an appropriate way. For example, by arranging a rear mesh panel 4 on a support, by connecting each of the cross mesh panels 7 to the rear mesh panel 4, and subsequently by connecting each of the cross mesh panels 7 to the front mesh panel 1. During the assembling it remains possible to pivot each cross mesh panel 7 with respect to rear front mesh panel 1 along the hinged connection 11 and/or to the rear mesh panel 4 along the hinged connection 12.

Once assembled, the fencing mesh assembly can have at least two states, an installed state and a compact state suitable for transport and storage. The fencing mesh assembly can be brought from the compact state, also named closed state, to the installed state, also named open state, for example when placing the fencing mesh assembly between two posts. In the compact state, the panel surface of the front mesh panel, the panel surface of the rear mesh panel and the panel surface of the cross mesh panels can almost be arranged in parallel to each other. This is possible in the example of Fig. 1 because the length of the short sides 16 of the cross mesh panels 7, in this example 200mm, is smaller than the distance between two respective hinged connections 11, 12 of two adjacent cross mesh panels 7 on each one of the front mesh panel 1 and the rear mesh panel 4, in this example 300mm. The hinged connections 11, 12 also ensure that the mesh panels can easily be brought from the installed state to a compact state, in other words from a unfolded positon to an folded position, and visa verse.

Fig. 4 to 7 show a fence 20 comprising three fencing mesh assemblies 10 according to the invention in installed state. In this embodiment, the front mesh panel 1 and the rear mesh panel 4 are arranged with their panel surface vertically, and the several cross mesh panels 7 of the fencing mesh assembly 10 are arranged horizontally. The fence 20 also comprises posts 21, 22, 23, 24 between which a fencing mesh assembly 10 can be mounted. Preferably, a fencing mesh assembly 10 is attached between the post 21 and 22, another fencing mesh assembly 10 is attached between the post 22 and 23, and still another fencing mesh assembly 10 is attached between the post 23 and 24. The posts 21 to 24 are anchored in the ground in a known way via a support in concrete (not shown).

In this example, the posts 21 to 24 are each formed by a profile 25 that has an elongated shape and has a rectangular cross section with sides of about 100mm x 200mm (width x depth). Above the ground, the profile 25 has a height that almost equals to the height of a fencing mesh assembly 10.

As shown in Fig. 5 together with in Fig. 1, a left lateral end 30 of the front mesh panel 1 of the fencing mesh assembly 10, can be attached to the right front side of the profile 25 of a respective post 21, 22 and 23, while a right lateral end 31 of the front mesh panel 1 can be attached to the left front side of the profile 25 of a respective post 22, 23 and 24. Similarly, a left lateral end 32 of the rear mesh panel 4 can be attached to the left rear side of the profile 25 of a respective post 21, 22 and 23, while a right lateral end 33 of the rear mesh panel 4 can be attached to the left rear side of the profile 25 of a respective post 22, 23 and 24. Due to this, the lateral sides of one fencing mesh assembly 10 are attached to the posts 21 and 24, and lateral sides of two fencing mesh assemblies 10 are both attached to the posts 22 and 23.

For attaching a lateral side of one fencing mesh assembly 10 to a post, a fixing system 40 can be used in such a way that a lateral end of a fencing mesh assembly 10 is sandwiched between a cover plate 41 and a respective profile 25 of a post, for example by using a number of fixation elements 42, such as bolts that are screwed through mesh apertures of the front mesh panel 1 or the rear mesh panel 4 into the respective profile 25. To this end, an elongated flat cover plate 41 having apertures (not shown) along which the fixation elements 42 can pass to be screwed in respective threaded holes (not shown) provided in the profile 25. The fixation elements 42 passing through the apertures in the cover plate 41 also pass between mesh apertures formed between wires of the mesh panel, which mesh panel 1, 4 is to be fixed to the respective posts. As can best be seen in Fig. 7, to this end each lateral side of a fencing mesh assembly 10 overlaps a front side or a rear side of a profile 25 of a post 21 to 24. As can best be seen in Fig. 5, each of the cover plates 41 is wider than the profile 25 to cover the profile 25 and is fixed with twenty fixations elements 42 to one post. Of course, other fixing systems are also possible, for example fixing systems as shown in EP 3149260 Bl.

Alternatively, instead of one profile 25, two almost identical profiles having a square cross section with sides of about 100mm x 100mm (width x depth) can be provided one next to the other, which profiles can be attached to one another by bolts or glue, or can be arranged one next to the other. Both the profiles can have a height similar as the profile 25, and have together an outer shape similar to the outer shape of the profile 25.

Such a fence 20 allows that a fencing mesh assembly 10 is sandwiched between two respective posts 21 to 24 and that further the fencing mesh assembly 10 can be attached to these two respective posts 21 to 24, by attaching the respective lateral sides of the front mesh panel 1 and/or the rear mesh panel 4 to a post 21 to 24, for example using a fixing system 40.

According to the invention, the cross mesh panels 7 of the fencing mesh assembly 10 are arranged such that each cross mesh panel 7 can vibrate with respect to the front mesh panel 1 and/or to the rear mesh panel 4 in installed state, in particular due to the hinged connection 11, 12, in particular due to the hinged connection 11, 12 comprising a helical wire member. This is particularly advantageous, because this allows that the cross mesh panels 7 can vibrate even if the front mesh panel 1 and the rear mesh panel 4 are firmly attached between posts 21, 22, 23, 24. Due to such vibrations, an intruder is hindered when attacking a fencing mesh assembly 10 using a grinding tool. Preferably, the cross mesh panels 7 are arranged horizontally in installed state so that the cross mesh panels 7 do not impede the visibility through the fencing mesh assembly 10. The fencing mesh assembly 10 according to the invention also offers the advantage that the front side of the fencing mesh assembly 10 is similar to the rear side of the fencing mesh assembly 10, so that the fencing mesh assembly 10 is useful against an attack from either side of fencing mesh assembly 10.
