Such fence systems are known. For their installation, first the grid element and the fence connector are aligned with each other. Subsequently, the two sub-elements of the fence connector are screwed together so that on the one hand fixed the grid element and on the other hand, the attachment of the connector is made possible on a fence post. The disadvantage here is that during assembly four parts must be aligned simultaneously relative to each other, namely the grid element, the first sub-element, the second sub-element and the post to which the connector is to be attached. Then the screw has to be screwed in. This is expensive and makes installation difficult. It is therefore desirable to facilitate assembly. However, since such fence systems are mass-produced, even small cost increases are undesirable.

The present invention has for its object to overcome disadvantages in the prior art.

The invention achieves this object by a fence system, comprising: at least one grid element and a fence connector, comprising a first subelement having a first clamping recess forming a half clamp, a first holding recess spaced from the first clamping recess in the region of one end of the first subelement and a first bore and a second subelement having a second clamping recess forming a half clamp, a second holding recess spaced apart from the second clamping recess in the region of one end of the second subelement and a second bore, wherein the subelements are aligned with each other so that the two half clamps form a clamp for fastening form on a fence post, the two retaining recesses form a recess for clamping a grid element and aligned the first and the second bore to each other for receiving a connecting element for permanent, reversible connection of the two sub-elements et are, characterized by a thread-free connecting means for restricting the freedom of movement of the sub-elements against each other.

According to a second aspect, the invention solves the problem by a grid element, in particular for a fence system according to the invention, with at least five mutually parallel transverse bars made of metal, parallel to each other and substantially perpendicular to the transverse bars extending longitudinal bars made of metal, with the transverse bars permanently are connected and thus form a grid with the transverse bars, wherein at least four of the transverse bars in each case directly adjacent in double row and separated by longitudinal bars, characterized in that between two each extending with another cross bar in a double row transverse bars at least one transverse bar extends, which does not run in a double row with another transverse bar. In this case, all rods are advantageously firmly interconnected. To increase the strength of the grid element, the bars are preferably interconnected at all points of intersection of the longitudinal bars and the cross bars.

According to a third aspect, the invention achieves the object by a fence connector, in particular for a fence system according to the invention, for connecting a fence post to a grid element, comprising a first subelement having a first clamping recess forming a half clamp, a first retaining recess spaced in the region from the first clamping recess an end of the first sub-element and a first bore and a second sub-element having a second clamping recess forming a half clamp, a second retaining recess spaced from the second clamping recess in the region of one end of the second sub-element and a second bore, wherein the sub-elements are aligned with each other in that the two half clamps form a clip for attachment to a fence post, the two retaining recesses form a recess for clamping a grid element, and the first and second bores are mutually opposed to receive a connecting element nts for permanent, reversible connection of the two sub-elements are aligned, characterized by a thread-free connection means for restricting the freedom of movement of the sub-elements against each other.

According to a fourth aspect, the invention solves the problem by producing a grid element according to the method described below. The method comprises arranging at least three transverse bars parallel to each other and in one plane, arranging at least two longitudinal bars perpendicular to the transverse bars on a first side of the plane of the longitudinal bars, arranging at least two transverse bars on the second side opposite the first side Level, so that the number of arranged on the second side of the plane cross bars is smaller than the number of arranged on the first side cross bars, and the welding of the cross bars with the longitudinal bars.

Preferably, the transverse rods and longitudinal bars are welded together by electrical contact point welding.

Cost-effective grid elements are produced in which, firstly, the distance from a transverse row extending in a double row to an adjacent, not with him in double row transverse bar for all cross bars is the same, second, the distance between two adjacent, each not in double row extending transverse bars is the same and thirdly, these two distances are equal. For a simple and easily automatable production of grid elements, it is expedient if the distance between adjacent longitudinal bars is the same in each case.

The indefinite articles, such as in the expression "a thread-free connection means for restricting the freedom of movement of the sub-elements against each other" are not to be understood as number words.

Under a half-shell forming clamping recess in particular clamping recesses are understood that are semi-curved. However, other forms are conceivable as long as the purpose is achieved that both clamping recesses can be combined to form a clamp. A clamp is understood to mean a component in which two parts movable relative to one another can be moved toward one another by at least one further part, for example one or two screws, and wherein both parts are designed to clamp another component between them.

For example, threaded, unthreaded or partially threaded blind or through holes can be considered as bores.

Two cross bars are considered to extend in a double row when the angle between a longitudinal bar and the connecting line through the centers of gravity of the cross sections of the transverse bars is a substantially right angle.

An advantage of the invention is that with the help of the connecting means, the freedom of movement of the sub-elements against each other in particular can be limited, when the grid element and the fence connector are positioned relative to each other. By restricting the freedom of movement of the sub-elements against each other is a pre-fixing, that is, a pre-assembly of the grid element relative to the connector achieved. The fitter can, for example, put the fence connector out of his hand in this state without the grid element and the fence connector separating from each other. In this state, the final, permanent, force-bearing connection, for example. By screws, easier to manufacture. This ensures that any Mehrfachmontageversuche be avoided.

Another advantage is that the solution according to the invention can be carried out very inexpensively.

The Advantage of Grids According to the Invention over Gratings in the Prior Art, where the crossbars always run in a double row, is that less material must be used for the production. The bending stiffness, however, is only slightly reduced in a grating element according to the invention compared to a grating element according to the prior art. Another advantage of a grid element according to the invention is its lower weight. During assembly, less force is required.

Advantageously, the cross bars all have the same length. Preferably, the longitudinal bars all have the same length. The longitudinal bars preferably extend exactly perpendicular to the transverse bars.

In a preferred embodiment, the transverse rods and longitudinal rods are round metal rods. It has been shown that the use of round metal bars leads to optically attractive grid elements. In addition, round metal rods are particularly easy to work.

The diameter of the transverse rods, in particular designed as round metal rods, is preferably between 4 mm and 8 mm, preferably 4 mm or 5 mm.

The diameter of the longitudinal bars is preferably between 5 mm and 6 mm, in particular exactly 5 mm and exactly 6 mm. It has been found that such a diameter leads to grid elements, which are at the same time stable and not too heavy with a suitable choice of the distances between the bars together.

Preferably, the longitudinal bars and transverse bars are welded together. A welded joint is a particularly durable connection. Preferably, the longitudinal bars and transverse bars are made of metal, for example steel or aluminum, and the longitudinal bars and transverse bars are connected to each other by contact welding points. In contact spot welding, the bars to be welded are pressed against each other. Then a strong electric current is sent through the contact points of the bars with each other. By this electric current, the material heats up strongly at the contact point, melts and forms a welded joint. For connecting the rods according to the invention, other connection possibilities can also be used, for example brazing or gluing.

In a preferred embodiment, exactly one transverse bar extends between two transverse bars running in double row. This results in an alternating sequence of double rows and not in double row extending transverse bars. By this measure, one obtains a rigid grid element, in comparison to grid elements according to the prior art is easier.

Alternatively, two, three, four or more cross bars extend between two transverse rows 5 running in double row. The more crossbars run between two crossbars running in double row, the easier the resulting grid element becomes. The individually arranged transverse rods can all lie in a common plane. Preferably, the individually arranged transverse bars are mounted on either side of the plane of the longitudinal bars. In this case, the individually arranged between the arranged in double row crossbars cross bars are in an alternating sequence in the planes on either side of the plane of the longitudinal bars, so that the adjacently lying in the lattice order individual transverse bars are arranged in opposite planes on both sides of the plane of the longitudinal bars. In this embodiment of the grid element according to the invention results in a much higher bending stiffness of the grid element relative to a grid element with all individual transverse bars in a common plane with the same weight of the grid elements.

Preferably (only) extend on both sides to extremely horizontal cross bars in 10 double row. In installation position of the grid element, the cross bars then extend, for example, above and below in a double row. The extending in double row cross bars then cause an increase in the bending strength of the grid element in the fence system most commonly occurring bending load. The distance between the double rows forming the longitudinal edges is preferably 40 cm to 200 cm. Alternatively or additively, all longitudinal bars are the same length and also have a length of 40 cm to 200 cm.

In a preferred embodiment, all of the longitudinal bars in a longitudinal edge of the grid element are flush with transverse bars that run in a double row. Preferably, the longitudinal bars close flush in installation position below with a double row transverse bars.

Preferably, between the mutually extremely excessive, extending in a double row cross bars no cross bars, which extend in a double row. It has been found that such a grid element is stable at the same time and is easy and inexpensive to produce. In this case, the transverse rods extending in double row preferably extend in the installed position at the upper and lower edges of the grid element.

In a preferred embodiment, all longitudinal bars, in particular approximately 10 mm to 40 mm, protrude beyond the extremely horizontal cross bar or the transverse bars that are too extreme at one longitudinal edge. Preferably, the longitudinal bars project beyond the upper longitudinal edge in the installed position. As a result, a grating element is obtained with Übersteigschutz.

It is preferred that the distance from a cross bar running in double row to the adjacent, not in double row transverse bar for all transverse bars is the same, the distance between two adjacent, each not extending in double row transverse bars is the same and these two distances are equal. In this case, results in a uniform in the transverse bars grid element.

Preferably, the distance between two adjacent transverse bars not running together in a double row is 200 mm or 400 mm. In this case, a grid element results whose grid spacing for the transverse bars is 200 mm or 400 mm.

Preferably, the longitudinal bars are arranged equidistantly. In this context, a grid in which transverse bars and longitudinal bars each extend perpendicular to one another is particularly preferred.

Preferably, the distance between two longitudinal bars 25 cm, 35 cm, 50 cm, 54 cm or 100 cm.

The maximum distance between two longitudinal bars, that is to say the width of the grid element in the case in which the longitudinal bars do not protrude beyond the two transverse bars lying to the extreme, is preferably 2 m to 2.50 m. The cross bars are preferably all the same length and have a length of 2 m to 2.50 m. Cross bars preferably close off with a longitudinal bar on the sides.

In a preferred embodiment of a fence connector, the unthreaded connecting means is formed by a recess having an undercut coupling recess in one of the sub-elements and a projection formed for positive engagement with the coupling recess in the other sub-element. If the projection engages in the coupling recess, then the freedom of movement of the two subelements is limited relative to one another in that both subelements can no longer be removed from one another at will and can only be moved in relation to one another within a small angular range. This angle range is for example less than 20 °. The projection and the coupling recess thus form a clearance with a wide clearance.

Particularly preferably, the coupling recess and the projection are designed for reversible interaction.

Particularly preferably, the coupling recess and the projection are L-shaped.

Alternatively, the coupling recess and the projection are mushroom-shaped. In order to restrict both sub-elements in their freedom of movement against each other, the mushroom-shaped projection is inserted into a shaft-shaped part of the mushroom-shaped coupling recess until the head of the mushroom-headed projection has reached the head of the mushroom-shaped coupling recess. In this position, the mushroom-shaped projection springs apart, so that a movement of the mushroom-shaped projection is inhibited out of the coupling recess.

In an alternative preferred embodiment, the connecting means is formed by a latching armature connected to one of the partial elements and a latching element connected to the other partial element and adapted to latch with the latching armature. If the two sub-elements moved toward each other, so the locking armature engages in the locking element. As a result, a further movement of the two sub-element against each other is difficult, but not prevented. The force that is necessary to move apart of the sub-elements, for example, is chosen so large that a preassembled at a fence connector according to the invention grating element, the two sub-elements can not be pressed apart. At the same time, this force, which is necessary for pushing apart, is selected to be so small, for example, that it is possible to move the sub-elements apart without machine force.

Preferably, both sub-elements have the same shape. In this case, two sub-elements can be joined together in the rotated by 180 ° state. This has the advantage that only one type of sub-elements must be produced.

In a preferred embodiment, the connecting means is formed by a film hinge, wherein the film hinge is disposed adjacent to the first clamping recess of the first sub-element and the second clamping recess of the second sub-element and the first and the second retaining recess is arranged respectively on the side facing away from the film hinge of the respective sub-element ,

Preferably, the first bore of the first partial element and the second bore of the second partial element are each arranged between retaining recess and clamping recess. The force exerted by a connecting element which extends through the two holes on the two sub-elements, distributed so particularly evenly on the clamping recess and the retaining recess. This results in a particularly favorable flow of power.

Preferably, the sub-elements are formed so that the half clamps a clamp with a Inner diameter of 35 mm to 55 mm, preferably 54 mm form.

In a preferred embodiment, the retaining recesses are aligned with each other so that they form a recess for clamping a grid element with a diameter of 4 mm to 8 mm, in particular 5 mm to 6 mm.

Preferably, the clamping recess ribs, which means that ribs protrude into the clamping recess. These ribs are in the mounted state of the fence connector, for example, on a fence post. In the vicinity of the ribs, this results in a particularly high clamping pressure, which is why the connection between the fence connector and pile is particularly strong.

Preferably, the first bore and the second bore for receiving a machine screw, in particular formed exactly a machine screw. The machine screw runs, for example, through both holes and is countered with a nut.

Preferably, the connecting means with at least one sub-element is firmly connected. In particular, the connecting means is fixedly connected to a sub-element and preferably an integral part of at least one sub-element. It is not necessary for the connecting means to be an integral part of at least one partial element. In a preferred embodiment, the connecting means is designed as a separate component from the sub-elements. As part of a pre-assembly, the connecting means is then firmly connected to one of the sub-elements. Since the bonding agent does not have to absorb excessively heavy loads, it is preferably made of plastic, such as PVC, polyethene (or even polyethylene, PE) or polypropene.

The fence connectors are preferably made of metal, for example. Steel or aluminum or plastic, such as PVC, polyethene (or polyethylene, PE) and or polypropene.

Fig. 1 shows a fence connector 10 made of PVC, comprising a first sub-element 12 and a second sub-element 14. The first subelement 12 has a first clamping recess 16 forming a half clamp. The first clamping recess 16 has a substantially cylindrical inner contour. Run perpendicular to the longitudinal axis of this cylindrical inner contour ribs 18, which protrude from the first sub-element 12 into the first clamping recess 16. In Fig. 1 Due to the perspective, only one rib is shown. The second sub-element 14 has a second clamping recess 20, which is constructed like the first clamping recess 16. In the second clamping recess 20 ridges 22 protrude.

The first sub-element 12 has in the vicinity of the first clamping recess 16, which forms a central part 24, a constant material thickness. The middle part 24 therefore has a substantially barrel-shaped outer contour. On either side of the central portion 24, a side arm 26 and 28 are integrally connected to the central portion 24, respectively. The second sub-element 14 is identical in construction to the first sub-element 12 and has a middle part 30 and two side arms 32 and 34.

Both sub-elements 12, 14 are constructed point-symmetrical. Therefore, only the structure of the side arm 34 will be explained in more detail below. The remaining side arms 26, 28 and 32 are constructed accordingly. In the side arm 34, a retaining recess 36 is provided, which passes through the side arm 34 parallel to the longitudinal axis of the clamping recess 22. Corresponding the side arm 32 has a retaining recess 38, the side arm 26 has a retaining recess 40, and the side arm 28 has a retaining recess 42. In the retaining recess 36 project two ribs 4 into it. Side arm 32 has corresponding ribs 46. The ribs of the two retaining recesses 40 and 42 are in Fig. 1 not shown.

Between the retaining recess 36 and the second clamping recess 20, a through hole 48 is provided in the side arm 34. A corresponding through hole 50 is also located in the side arm 32, a through hole 52 is located in the side arm 28 and a through hole 54 in the side arm 26th

At the outermost, the second clamping recess 20 side facing away from the side arm 34 is a feather key 56. On the opposite side in the side arm 32, a groove 58 is provided. A corresponding groove 60 is inserted in the side arm 26 of the first partial element 12, which is on the opposite side of the groove 60 of the first partial element 12 key 62 is in Fig. 1 not visible.

Between the retaining recess 36 and the second clamping recess 20 is adjacent to the through hole 48, a mushroom-shaped projection 64 which includes a shaft 66 and a head 68. The mushroom-shaped projection 64 is slotted in its longitudinal direction, wherein the slot extends through the longitudinal axis and completely penetrates the mushroom-shaped projection 64 in the transverse direction.

The mushroom-shaped projection 64 forms an integral part of the second partial element 14. In an alternative embodiment, the mushroom-shaped projection is formed on an insert which is inserted or insertable into a recess in the second partial element 14.

Also located between the second clamping recess 20 and the retaining recess 36 is a mushroom-shaped recess 70. The inner dimensions of this mushroom-shaped recess 70 are slightly larger than the outer dimensions of the mushroom-shaped projection 64. In the side arm 32 is a corresponding mushroom-shaped projection 72 and a corresponding mushroom-shaped recess 74. In the side arm 26 of the first partial element 12 is a mushroom-shaped projection 76 and a in Fig. 1 not shown in the mushroom-shaped recess 78. In the side arm 28 of the first sub-element 12 is a mushroom-shaped projection 80 and a mushroom-shaped recess 82, both in Fig. 1 are not shown.

If both sub-elements 12, 14 are moved toward one another, then the mushroom-shaped projection 64 of the second subelement 14 engages in the mushroom-shaped recess 78 of the first subelement 12 (see. Fig. 2a ). Accordingly, the other mushroom-shaped projections 72, 76, 80 engage in the respective associated mushroom-shaped recesses 74, 78, 82. When inserting the mushroom-shaped projection 64 into the mushroom-shaped recess 78, the head 68 is first compressed. If the mushroom-shaped projection is inserted sufficiently far into the mushroom-shaped recess, the head 68 snaps apart, so that both partial elements are permanently but reversibly connected to one another. In this state, both sub-elements are not completely against each other, but can move relative to each other with play. This situation is in Fig. 2b shown.

When the mushroom-shaped protrusions are engaged in the mushroom-shaped recesses, the feather keys 56 and 62 are located in the respective associated grooves 60 and 58. In this state, moreover, the first clamping recess 16 and the second clamping recess 20 form a clamp. This clamp is designed to include a fence post. The two retaining recesses 36 and 40 on the one hand and 38 and 42 on the other hand form in pairs a recess to terminals of a grid element. In this position of the two sub-elements 12, 14 to each other, the through holes 48 and 54 on the one hand and 50 and 52 on the other hand aligned with each other so that they merge into each other. For final assembly, a machine screw not shown here is inserted through the respective holes and tightened. The two sub-elements 12, 14 are then fixed, but reversibly connected to each other and attach a grid element not shown here on a fence post, also not shown here.

Fig. 3 shows two sub-elements 12, 14, which are each shown only in half. The first sub-element 12 has at its one end an L-shaped projection 84. The second sub-element 14 has on the corresponding opposite side an L-shaped recess 86. The L-shaped projection 84 and the L-shaped recess 86 form a clearance fit in the connected state, which restricts the freedom of movement of the sub-elements against each other.

Fig. 5 shows a fence connector 10, in which the sub-element 12 comprises only one side arm 26, the second sub-element 40 comprises only one side arm 34. On the side opposite the side arms, the two middle parts 24, 30 are connected to each other via a film hinge 88. The two sub-elements 12, 14 are made of PVC. The film hinge 88 is formed by a material taper, so that both sub-elements can be pivoted against each other with little effort.

Fig. 6 shows the fence connector in a side view, Fig. 7 in a view of the movie hinge 88th

Im in Fig. 10 partially shown fence connector 10, the first sub-element 12 at its one end a locking element 90 which cooperates with locking anchors 92a and 92b. The latching anchors 92a, b have latching heads 94a and 94b, the latching element 90 latching recesses 96a, 96b, 96c, the two sub-elements 12, 14 moved towards each other, so slide the latch anchors 92a, 92b with their locking heads 94a, 94b from detent recess to detent recess and thereby execute a pivoting movement, the pivot axis is perpendicular to the longitudinal axis of the two clamping recesses 16, 20. By the locking element, a movement of the two sub-elements 12, 14 inhibited in a translational degree of freedom, namely in the movement towards each other, in the two translational degrees of freedom perpendicular to this degree of freedom, the freedom of movement of the sub-element is prevented against each other with play.

Fig. 11 shows the fence connector Fig. 1 0 in a central longitudinal section perpendicular to the longitudinal axis of the clamping recess 16.

Fig. 12 shows an alternative arrangement of a locking means. In this case, the latching armature 92 is arranged relative to a latching element 90 such that, when both sub-elements 12, 14 move toward one another, it performs a pivoting movement, the pivot axis of which runs parallel to the longitudinal axes of the first and second clamping recesses. The two sub-elements are only partially shown.

Fig. 14 shows a grid element 100 comprising seven transverse bars 102a, 102b, ... 102g. The crossbars 102b and 102g are not visible in this figure. The bars are all parallel to each other. As in the side view in Fig. 15 the crossbars 102a and 102b, as well as 102f and 102g are in double row. Perpendicular to the transverse rods 102a-f extend six longitudinal bars 104a, 104b,... 104f (cf. Fig. 14 ). As in Fig. 15 shown, the longitudinal bars 104a to 104f are all parallel to each other and in a plane. All transverse bars 102c, 102d, 102e, which do not run in a double row, and in each case one of the transverse bars which run in double row, are also located in one plane. The transverse bars 102a and 102b, as well as 102f and 102g), which run in a double row, are separated from one another by the longitudinal bars.

All cross bars have the same length. All longitudinal bars are the same length. However, the length of the cross bars differs from the length of the longitudinal bars. The cross bars and the longitudinal bars are basic metal bars. The diameter of the cross bars is 6mm, the diameter of the longitudinal bars 5mm.

The transverse rods 102a to 102g terminate on both sides in longitudinal bars 104a, 104f. 25 The longitudinal bars, however, protrude beyond the transverse bars 102a, 102b, 102f, 102g that are too extreme. The transverse and longitudinal bars form a uniform grid. The distance a of two adjacent, not together in double row transverse bars is 20cm, the distance b of two longitudinal bars is 25cm.

At their points of contact, the longitudinal bars and the transverse bars are welded together, as exemplified by a weld point 106 in FIG Fig. 15 shown.

Fig. 16 shows a grid element 100, in which all the longitudinal bars in a longitudinal edge of the grid element, namely the in Fig. 16 located below, with transverse bars flush, which run in a double row (see. Fig. 17 ). On the opposite side, in Fig. 16 above, the longitudinal bars over 45mm on the overlying transverse bars 102a, 102b over.

Fig. 18 and Fig. 19 show a further advantageous embodiment of a grid element 100, which exemplifies - like the grid element according to Fig. 14 and Fig. 15 - Six longitudinal bars 104a, 104b, ... 104f extending perpendicular to the transverse bars 102a-f. The longitudinal bars 104a-104f lie in a common plane. At the upper edge and at the lower edge of the grid element 100 are each extending in a double row transverse bars 102a, 102b and 102f, 102g provided, of which the cross bars 102b and 102g in the front view Fig. 18 covered by the overhead cross bars 102a and 102f and therefore are not visible.

Between the transverse rods lying in double row, three individual transverse rods 102c, 102d, 102e are arranged. The individually arranged transverse bars 102c, 102d, 102e are mounted on either side of the plane of the longitudinal bars 104a-104f. The individually mounted crossbars 102c, 102d, 102e lie in an alternating sequence in the planes on both sides of the plane of the longitudinal bars 104a-104f, so that the individual transverse bars 102c, 102d, 102e lying adjacent to each other in the lattice order lie in opposite planes on both sides of the plane of the longitudinal bars 104a - 104f are lost. In the present exemplary embodiment, two transverse rods 102c and 102e are provided in the plane of the transverse rods 102a and 102f lying in front in the double row. The transverse bar 102d running centrally in the grid element is arranged in the opposite plane in which the transverse rods 102b and 102g of the double rod row are located. The arrangement of the individual transverse bars on both sides of the longitudinal plane of the bar results in a significantly higher flexural rigidity of the grid element 100 with respect to bends about a longitudinal axis in the alignment of the longitudinal bars of the grid element 100. Due to the alternating arrangement of the individual transverse bars can increase the bending stiffness, the total weight of the grid element 100 be kept low.
