Abstract

PCT No. PCT/DE94/01331 Sec. 371 Date May 17, 1996 Sec. 102(e) Date May 17, 1996 PCT Filed Nov. 10, 1994 PCT Pub. No. WO95/14144 PCT Pub. Date May 26, 1995A fence comprises posts and lattice panels which are fixed at their vertical edges to the posts. The post carries, on its front side, hooks, on which the horizontal bars of the lattice panels rest. The lattice panels are clamped between the front side of the post and the rear side of a hollow front profile which have on the rear side, at the locations of the hooks, holes, into which hooks penetrate with a leg directed obliquely outward and upward. The upper hole edges slide downward on the slope formed on the upper side of the legs and at the same time displace the front profile toward the post. The front profile is pressed downward by a holding-down device.

Description

The invention relates to a fence of the Preamble of claim 1 corresponding type.

Such a fence is known from EP 472 760 A1. In the known fence, the lattice panels comprise vertical bars, horizontal bars on both sides at the same height are attached. The rods are made of directed Round wires made of steel from 4 to 10 mm in diameter, those at the crossing points by resistance welding are interconnected. However, the invention is not tied to this formation of the grid panels. It can also use cross sections other than round material and there can be the horizontal bars attached in pairs be replaced by profile material, which one results in increased bending strength in a horizontal plane, for example bars with a rectangular cross section, with a U cross section or the like.

The posts can be made from the generic fence consist of a rectangular hollow profile; in this case the hooks are attached to the front of the hollow profile. The posts can also be made of latticework consist; in this case the hooks are followed by a protruding extension of horizontal bars at the front of the post. The hooks include in the known Embodiment a horizontal leg attached and a free leg bent upwards, its distance from the front of the post the outer Width of two horizontal bars adjacent at the same height corresponds to the grid panels. The grids are hooked into the hooks using the horizontal bars and then fixed by screws so that a Removing the double horizontal bars or the Lattice boards from the hook is prevented. In one embodiment the free ends of the hooks after the Hanging the lattice panels bent over the horizontal bars, to fix it vertically.

The known way of connecting the lattice panels with the post is simple, but has disadvantages. A The disadvantage is that there is no guarantee that the horizontal bars are held under tension. she have something on the hook perpendicular to the fence surface Game, which means that under the influence of the wind vibrations to unpleasant whirring noises to lead. The same applies if, for example, a ball is on the grid panel hits.

In the embodiment in which the fixation by The free leg of the hook is bent Corrosion protection of the lattice panels endangered. These are exposed to the weather for many years and accordingly carefully protected against corrosion, for example by a Galvanizing and a plastic powder coating on top. These corrosion protection measures suffer when the upward free legs of the hooks against be bent over the front of the post, either with a tool, be it what is not excluded in practice can be with a hammer. Kick here Significant stretching of the coating due to its extensibility and overwhelm liability and to local Cracks and breakthroughs as well as peeling of the coatings Are occasion. These places are the starting point for Corrosion and hardly effective to repair.

The invention has for its object a generic To design the fence so that the attachment is improved and the grid panels on the posts are noiseless are held.

This object is represented by the one in claim 1 Invention solved.

So it will not be easy with the invention Lattice board supported vertically and against vertical displacement fixed, but it is done with the vertical Relocation of the lattice panels towards the hooks through the at the same time a slope is formed of the lattice panels perpendicular to their surface against the Posts so that they are not just draped, but are also braced perpendicular to their surface. So it is there is no more play in this direction, so that noises Avoided by the wind, balls, etc. are. It is important that this improvement without the Use of individually assembled fasteners such as Screws or the like can be achieved. This diminishes the effort for the fence considerably.

The hooks have a certain elasticity, so that any manufacturing tolerances of the lattice panels and also the Hooks can be compensated. So if there is a catch Example with its slant on the front of the post is too close together, it will undergo elastic deformation when moving vertically some of the post pushed away, so that the uniformity of the system about the height of the grid panel and an even tension adjust to the full height.

The term "slant" is not only meant to be the case be meant that the hook on the effective side of your "sloping" hook legs run straight; also in hook legs that run with a certain curvature be included, provided that the general direction of the course described function of the wedge-like bracing enables.

A slope is also taken on the fence according to DE-U-92 05 376 available, but not on the Fence posts, but in the upper area of the outside one that extends vertically in front of the fence post Clamp. It is angled upwards Retaining pin formed after attaching the Mesh mat is inserted to attach the mesh mat to a To prevent slipping down. The holding pin has not the function, the mesh mat wedge-like against the To brace the post.

Slopes also emerge from FR-A-2 264 149, but not on hooks attached to the post, but on a vertical bridge perpendicular to the fence surface in Shape oblique incisions are provided. This embodiment does not wedge the grid panels like a wedge against the fence post and also places one over the Fence area protruding to the front of the web leading to Injury.

The invention can be implemented in two embodiments become.

The first embodiment is the subject of the claim 2. So here is an additional curtain profile provided which either itself with the slopes cooperates on the hook by punching the Intervene curtain profile, or which carries the hooks, so that they interact with the post.

The invention has already been implemented if the curtain profile only extends over part of the height of the Post, but is in the preferred embodiment the curtain profile at the full height of the Post provided. This configuration is special therefore advantageous because the lattice panels by actuation of the hold-down device over its entire height at the same time get jammed, causing any by relative movements caused between the posts and the lattice panels Rattling noises can be avoided.

The alternative embodiment is the subject of Claim 3 and comes without an additional curtain profile out. The grid panel itself acts with the slope together on hooks attached to the post, or there are the hooks formed on the grid panel, which then immediately attack the post.

If the bracing of the lattice panel on the post through sliding over the slope and simultaneous shifting in the vertical and perpendicular to the fence or Grid panel area is to be achieved, there is the more extensive Task, the tension once achieved permanently maintain.

For this purpose, a holding element according to claim 4 can be provided be, which also helps to achieve the tension, i.e. on the vertical displacement of the curtain profile or the grid panel can at least participate (claim 5).

Claims 6 and 7 give alternative directions of attachment the catch again.

According to claim 8, the hooks on the front of the post.

The designs required for this on the posts are minor. The hooks only need that Post profile on the front by means of stud welding to be attached. For example, there is no need to attach it of weld nuts or press nuts and the like, as is the case with a fastening of the lattice panels Screws would be required. In one embodiment with the free leg of the hook pointing upwards the grille panels can be hooked into place with one hand be hung up. It will then either be a curtain profile or the grid panel itself by pressing the hold-down device, possibly supported by one or other hammer blow, shifted vertically while doing so pressed against the post at the same time. So that's it Fastening the grid panels already under tension reached.

The hooks can also be on the back of the curtain profile be attached (claim 9).

The hooks engage in perforations on the front of the post profile. This embodiment has the advantage that the curtain profile can be particularly flat can, since now the free ends of the hooks when tightening of the hold-down device in the cross-section of the post penetration. The material cost of this embodiment is reduced.

In embodiments where the curtain profile or the lattice panel when tightening downwards is shifted, the holding element is designed as a hold-down device, of the two elements mentioned above Push the post down (claim 10).

Claims 11 to 15 give further structural designs of the holding element again.

The design of the holding element as a molded part (Claim 15), which made of metal or plastic Pouring, pressing or spraying is opened Possibilities of design, the holding element give a decorative look at the same time.

When dimensioning and arrangement according to claim 16 ensures that when a plate-shaped hold-down rests on the top of the post, at the same time the grating of the grid panels has been reached. To this A kind of stop is formed, which results in that the hold down on the top of the post not paying as much attention to pulling forces must become.

To apply the curtain profile or the lattice panels depressing force can be at least one vertical screw provided on the post by means of which the bracing is carried out (claim 17).

The thread for the screw can, for example by one on the inner wall of a hollow profile existing post welded nut provided be (claim 18).

One for a number of reasons such as tension, Stackability, good attachment area for welding the hook or existence of a sufficient Internal volume to accommodate the free ends of the hooks and preferred embodiment also because of the calm, smooth appearance of the post is that of a rectangular hollow profile (Claim 19).

Here it is recommended that the curtain profile is a rectangular profile (claim 20). This can be a Rectangular hollow profile when the hooks in the interior should occur, or a solid rectangular profile, i.e. a flat steel.

The mentioned advantages of the rectangular hollow profile are then also available for the curtain profile. Also complete the two rectangular shapes are most likely to form a uniform, giving a calm and solid impression Shape. Other cross-sectional shapes such as semicircular hollow profiles are not excluded.

With a rectangular profile as a curtain profile needs this just to be flat. Even when training as Hollow section only has to have enough space inside the Profiles for the entry of the hooks should be provided. A such profile should be "flat" in front of the Front surface of the post to be put and what for other cross sections of the curtain profile apply that have the same width as the post (claim 22).

For one attacking at the top of the post Screw for actuating a hold-down device for the grid panel or the curtain profile can instead of a mother a support structure according to claim 23 is provided be.

Such a holding piece is easy to manufacture and is positively supported at the upper end of the post whose bore with the cone-like approach.

The plate-shaped component forming the holding element can according to claim 24 have a perforation of one at the upper end of the curtain profile or the grid panel attacking screw is penetrated.

The holding element is here on the top of the Fixed post and serves to pull up the curtain profile or the grid panel, which for this purpose Claim 25 can be designed.

In a first embodiment reproduced in claim 26 the invention is on each post or on each curtain profile only one row vertically one above the other Hooks provided on which the edges are adjacent Lay on lattice boards. Cover the grid panels here in a vertical border area. This is coming especially when the grids are vertical Single bars and horizontal double bars on both sides of vertical single bars. Here, in the front horizontal bars in a vertical edge area one grid, in the neighboring grid the rear horizontal bars have been omitted. If covering these marginal areas is the total thickness of the The lattice structure is also not larger in the coverage area than in the free lattice area, where they are essentially is determined by three-wire. The lattice has the embodiment mentioned essentially everywhere the same thickness.

Another possible embodiment is for butt joints at the vertical edges Lattice panels provided (claim 27).

Two rows next to each other are vertical superimposed hook available, the a grid panel with its vertical edge in it facing hook, the other grid panel with its vertical Edge engages in the other hooks.

The area on which the fence is not always is set up exactly horizontally. Nor is it always wanted the bottom of the lattice panels is always at the same height above the ground.

The embodiment according to claim 24 facilitates one Adjustment in the cases mentioned. If the fence is on one Slope must be built, the slope can be mastered be stepped by successive grid panels be offset in height from each other. The steps do not need the hooks in the reduced division equal to the vertical division of the lattice panels. Of course, this also applies to the attachment of Lattice boards in flat terrain, but in different Heights.

As already mentioned, the invention comprises two basic principles Embodiments, namely with and without curtain profile.

The latter embodiment can in particular realized in the manner described in claim 29 become.

The hooks are attached to the post. The Lattice board is shifted vertically, especially to Hooks placed on top and shifted downwards. This results in a simultaneous with the simplest means Determination at all determination points.

An important embodiment in such a Embodiment is given in claim 30.

The formation of the free legs of the attached to the post Hook to an eyelet is reduced to the simplest Way the risk of injury. The free end of the eyelet can run obliquely and the one causing the tension Form slope (claim 31).

This embodiment has the advantage that the slope has a certain elasticity and tolerances of Hook training and attachment can be balanced. So it is without excessive effort in this Embodiment to achieve that at all fixing points a resilient bracing regardless of the tolerances the grid panel is against the post.

Especially in this embodiment, that is Hooks and horizontal bars of the grid panel immediately cooperate, but not exclusively with this Embodiment, the holding element can be one on the hook and the horizontal bars interacting with it attacking clamp (claim 32), the horizontal bars and pulls the hook vertically against each other.

Just like the hook in the embodiment with Curtain profile either on the post or on the curtain profile may be appropriate is also the embodiment of importance where the hooks on the grid panel are attached and in a perforation in the front wall engage a post consisting of a hollow profile (Claim 33).

As already mentioned, the incline The hook legs are straight or curved, as long as the relative movement along the post at the same time the pressure against the post occurs (claims 34 and 35).

For the invention, not only the features of the in the features mentioned in each case individually, but also any combination of these features with each other essential.

Of the one designated 100 as a whole in FIG. 1 Fence can be seen in Fig. 1, two fence posts 10, between which extend rectangular grid panels 20, that form the fence area and on its vertical edges are clamped to the fence posts 10.

As can be seen from Fig. 3, the grid panels exist 20 from vertical bars 1 and in pairs arranged at the same height on both sides of the same horizontal bars 2, which stiffen the grid panel 20. The bars 1 and 2 are at the crossing points with each other on a grid welding machine Resistance welding connected. The grid panel 20 will following the usual welding procedure for corrosion protection such as galvanizing and / or powder coating subjected.

From Fig. 3 it can be seen that in the post 10th adjacent edge area of the right grid panel 20 die each rear horizontal bars 2 'are slightly shorter than the front horizontal bars 2 "on the left edge of the right grid panel alone with the last vertical bar there 1 'are connected. In the left in Fig. 3 Grid panel 20, the situation is reversed. The each shortened horizontal bars 2 'are the front here Horizontal rods and the longer horizontal rods 2 " rear horizontal bars alone at their free end are connected to a vertical rod 1 "there Grid panels 20, 20 overlap with their vertical ones Edges such that the 20 belonging vertical rod 1 'of FIG. 3 to the left of the vertical bar 1 "belonging to the left lattice panel 20 lies. The total thickness is in the overlap area the arrangement as well as in the free area of the two Lattice panels 20 from the two horizontal bars 2 'and 2 " and the intermediate vertical bars 1 'or 1 "

As can be seen from Fig. 3, are on the plane Front surface 10 'of the by a rectangular hollow profile (for Example 40 x 60 x 2 mm) formed post 10 in one Row lying one above the other in the middle of the front surfaces 10 ' Hook 3 provided by means of stud welding butt-welded onto the front surface 10 are. In the detail of Fig. 3, i.e. in the area below of the post 10, the vertical division of the Hook 3 matches that of the grid panels 20, i.e. it is for each pair of horizontal bars 2.2 a hook 3 in suitable height provided. The division of the lattice panels 20 can, for example, 200 mm in height and 50 mm in Horizontal.

In the state shown in Fig. 3 are the Lattice panels 20 only placed on the hook 3. The fastening of the lattice panels 20 to the posts 10 takes place in this embodiment by means of curtain profiles 30, also as rectangular hollow profiles (for Example 20 x 40 x 2 mm) are formed and with the Flat side are arranged in front of the posts 10. The Curtain profiles 30 extend over the entire height the post 10. The curtain profiles 30 serve the Grid panels 20 on the front surface 10 'of the posts 10 tense.

For this purpose, the curtain profiles 30 are on the Back with perforations 4, which are in places the hook 3 are. 2 is a curtain profile 30 loosely leaned against a grid panel 20. The perforations 4 can only be found on the assembled front surface 10 'of the post 10 facing side, while the remaining three sides of the curtain profile 30 undamaged and are smooth. Only these smooth sides are for the viewer recognizable, the otherwise no fasteners see how can be seen from Fig. 1.

The function of the curtain profile 30 is in FIG. 4 explained. The hook 3 are from the front surface 10 'of Post 10 before. They consist of a perpendicular to the Front surface 10 'extending attached, i.e. on the end B welded leg 3 'and a bent, in the embodiment pointing obliquely upwards free leg 3 ", on the front surface 10 'of which Post 10 facing the top formed a slope 5 is. The slope 5 thus approaches from the end E of the free leg 3 "away against the attached leg 3 'towards the front 10' of the post 10. The in the Back 30 'of the curtain profile 30 provided perforations 4 are large enough that after placing the lattice panels on the hook 3 or its horizontal leg 3 ' the obliquely upward pointing leg 3 "without difficulty inside the hollow curtain profile 30 can be introduced. The upper perforation edge 6 lies doing so on the slope 5. At one the curtain profile 30 the downward force of the perforated edge 6 slides down the slope and at the same time against the Front surface 10 down. So when you press down, it becomes Curtain profile 30 simultaneously shifted against the post 10, so that the lattice panels 20, 20 with each other adjacent vertical edges between the front surface 10 'of the post 10 and the rear 30' of the curtain profile 30 are clamped. Since the curtain profile 30 preferably extends over the entire length of the post 10, the grid will be between its entire height pin the post 10 and the curtain profile, which prevents rattling noises.

The slopes 5 of the hook 3 do not have to, as in the most of the exemplary embodiments and in particular in FIG. 4 shown, run straight. 6 is an after curved hook leg 3 "'can be seen, the" slope " 5 is curved upwards. The wedging effect the perforated edge 6 also occurs here. It only comes to the fact that the perforated edge 6 locally on a counter surface the right angle to hit when depressed the curtain profile 30 at the same time the pressure to generate against the post 10. This affects the cases in which a round hook leg 3 "'deliberately welded on will, as well as cases in which hook legs 3 " as was sought in Fig. 4, but due to manufacturing Difficulties are a bit crooked. As long as the general direction is right, all of these are Embodiments useful. This applies to all shown Designs of the fence.

In order to bring the curtain profile 30 down or a depressed position of the curtain profile 30 is a corresponding holding element provided in the form of a hold-down 7, the consists of a rectangular sheet metal plate 7 ', the edges of which 7 "are angled downwards. The rectangular Sheet metal plate 7 'just covers the floor plan of the post 10 and the curtain profile 30 attached in front, wherein embrace the edges 7 "both on the outside Embodiment of FIGS. 4 and 5 is inside the Post 10 on the wall forming the front surface 10 ' welded a nut 8 into which a screw 9 is screwed in, the hold-down 7 from above against pulls the upper end of the post 10 down while doing so the curtain profile 30 presses down. The dimensioning the hook 3 is made so that when the system is reached on the upper end of the post, even the vertical edges of the lattice panels 20, 20 between the Front surface 10 'of the post 10 and the rear 30' of Curtain profile 30 are optimally tensioned. The slope 5 of the leg 3 "angled upwards and outwards closes in the embodiment with the horizontal an angle of about 60 °. The length of the leg 3 ' the hook 3 must be dimensioned so that it is somewhat less than the thickness of the lattice panels is 20.20, so that the Back 30 'of the curtain profile 30 already on the front of the front horizontal lattice bar 2 ", before the upper perforated edge 6 'the height of the top of the leg 3 'perpendicular to the front surface 10' Has. So there must be another one caused by the slope Relocation of the curtain profile 30 against the post 10 can take place when the first touch of the back 30 'with the horizontal bars 2 "has occurred.

In Fig. 3 it can be seen that the hook 3 between the terminal vertical bars 1 ', 1 "of the lattice panels 20 reach through. Both grid panels 20 are on this Way against horizontal pulling from the post 10 fixed. It is only one row vertically one above the other Hook 3 in the middle of the front surface 10 'provided, as is also in the upper half of Fig. 5 is shown.

In an alternative embodiment, as from 5, two each Hook 3 provided next to each other at the same height the vertical edges of butt-jointed lattice panels attack, of which only one horizontal wire at a time 2 "'and a terminal vertical wire 1" indicated is. It is understood that the curtain profile 30 in such cases on his not recognizable in Fig. 5 Two perforations 4 next to each other on the back having.

Figure 6 shows a view of the top of the post 10 corresponding to FIG. 4, but with the screw 9 for the hold-down 7 not on one of the posts 10 welded nut, but in the threaded hole of a Holding piece 11 attacks, which consists of an angled Flat iron exists, which on the of the bend 11 ' opposite end a centrally protruding pin-like Approach 31 has that in a transverse bore 32 of the Post 10 engages. The distance of the top of the Cross bore 32 from the upper end of the post 10 and the Height of the bend 11 'match, so that the Screw 9 when resting on the flat end of the post 10 Sheet metal plate 7 'in the apparent from Fig. 6 Way, the holding piece 11 in the near of the front 10 'forming wall of the post 10 located threaded hole 33 can reach vertically and no constraints occur.

The hold-down device 17 of FIGS. 7 and 8 consists of an aluminum casting, which corresponds to the floor plan of the Post 10 and the curtain profile 30 overlapping plate-shaped part 17 'and projecting downwards Edges 17 "includes the post 10 and that Grasp curtain profile 30 on the outside. Through the Freedom of design for casting or similar molding processes can hold down 17 a decorative appearance and also given a special resilience be allowed to depress the curtain profile 30 apart from just the screw 9 also one To take hammer blow to help. The screw 9 passes through the plate-shaped part 17 'in a bore 12.

9 is another embodiment of a Fences according to the invention shown, in which the Hold-down 7 consists of a plate-shaped component 33, which at the top horizontal end 30 "of the curtain profile 30 is welded. Pulling that down shaped hold-down 7 takes place according to the in the 4 and 5 shown and described above Embodiment by means of a screw 9, which in one on the inside of the front wall of the post 10 welded nut 8 engages. Also in this embodiment is by tightening the screw 9 the curtain profile 30 has a downward force exercised. The hook 3 can then, as in the upper part of Fig. 9 shown, angled upwards and on the carrier be welded or, as in the lower part of FIG. 9 shown, angled downwards and on the - here as massive rectangular profile, i.e. as a flat steel section configured - curtain profile 40 to be welded. The Holes 4 are then incorporated into the post 10.

10 to 13 are various possible Embodiments of the post 10 and the curtain profile 30 shown in horizontal cross section. 10 and 11 is the post 10 again from a rectangular hollow profile manufactured. Fig. 12 shows a post 10 " a solid T-profile, the hook 3 either on the Crossbars of the "T" are attached (as shown in Fig. 12) or also on the bridge of the "T". It is also an embodiment of the post 10 "'possible as a grid element (Fig. 13), which consists of two pairs of opposite vertical bars 34,34 ', horizontal between the pairs Cross bars 35 are arranged which are fixed to the Vertical bars are connected. To the front 10 'of Post 10 "'out the cross bars 35 are above the vertical bars 34,34 'and are angled vertically, see above that their protruding parts 35 'form the hook 3.

10 to 13 are different embodiments represented by curtain profiles, each with the different posts 10, 10 ", 10" 'also in other combinations than shown in the drawing are usable. 10, the curtain profile 30 of a flat rectangular hollow profile 36 is formed, which in the perforations to a wall facing the post Includes the hook. This embodiment corresponds 4 to 6 and 9. However, it is also possible - as shown in FIGS. 11 and 12 - to use a C-profile 37, 37 'as curtain profile 30, whose lateral edges 38, 38 'follow by at least 180 ° are bent over at the front so that the free ends E of the hooks 3 not over the front boundary surface of the curtain profile 37.37 'survive. Also, as shown in Fig. 13, a tubular formation 39 of the curtain profile applicable.

14 is an embodiment in the upper part of the figure of the fence according to the invention, where the hook 3 on the as a solid flat steel section designed curtain profile 40 are attached. The perforations 4 are incorporated into the posts 10. As a holding element is used in this embodiment on the horizontal upper end of the post 10 welded plate-shaped Component 41, which in turn the floor plan of Post 10 and the curtain profile 40 covered. By doing protruding beyond the front 10 'of the post 10 Area 41 ', the plate-shaped component has a bore 42 through which a screw inserted from above 9 'engages. At the upper end of the curtain profile 40 is a inwards, i.e. against the front 10 'of the post 10 projecting fitting 43 welded, which a Has hole for the passage of the screw 9 ' can be screwed into a nut 44 arranged underneath. By tightening the screw 9 ', the curtain profile 40 against the post 10 so high that it through the attack of the slopes 5 of the hook 3 at the top the perforations 4 simultaneously in the direction of the post 10 is pressed. In this embodiment, in which So when tightening to the curtain profile 30.40 one after force is exerted, it is - as in shown lower part of Fig. 14 - also possible attach the hooks 3 to the posts 10, the hooks then angled down and into the in the curtain profile 30 arranged holes 4 engage.

As can be seen from Fig. 2, the division is correct the hook 3 is not completely with the division of the horizontal bars 2 of the grid panels 20 match. The bottom three Hook 3 and the uppermost hook 3 each carry horizontal bars 2. The remaining hooks 3 are in other places, what an attachment of the grid panels 20 in different Height or a height offset adjacent Grid panels 20 on the construction of the fence enable an inclined terrain. In the embodiment is the vertical division of the grid panels 20 200 mm. The second hook 3 from the top has the top Hook 3, however, a distance of 250 mm, and this Pitch of 250 mm is also the two below Hook 3 adhered to. For catching the weight of the Grid panel 20 and for hanging during assembly it is sufficient if a grid panel only on a hook 3 lies on. Due to the arrangement shown, it is for example possible, the right grid panel 20 50 mm lower than mount the left grid by clicking on the second one Hook 3 is placed from above. A hang up on the hook 3 underneath enables a gradation of 100 or 150 mm.

When assembling the embodiment according to FIG. 1 8 to 8 are the grid panels 20 in the desired manner placed on the hook 3. Then in front of each post brought the curtain profile 30 into position, the Enter the hook 3 into the holes 4. Then through Tightening the screw 9, possibly supported by a corresponding hammer blow, the vertical shift of the curtain profile 30 down and the bracing the grid panel against the front surface 10 'of the post 10 accomplished. The assembly is now complete. It does not require the screwing in of a large number of Screws or similar assembly processes. The finished fence is characterized by a calm and solid appearance out. No fasteners are visible. The Curtain profile 30 has the same width as the fence post 10 and optically forms a unit with this.

15 to 17 is an embodiment shown, which differs in two respects from the previous Embodiments differs: on the one hand the post 10 does not consist of a rectangular hollow profile, but in turn made of grid material vertical rods 51, 51 'lying opposite one another in pairs and between these extending horizontal bars 52, which protrude beyond the front 10 'of the post 10 and form the hook 3 there. The area of the mesh material this post 10 extends perpendicular to Fence area. At the top of this post 10 is a suitable completion provided. Done at the bottom fixing to a foundation in the usual way.

The protruding ends of the horizontal rods 52 form the "attached" legs 3 'of the hook 3. Die "Free" legs 3 'are essentially one extending upwards parallel to the fence surface Eyelet 53 bent, the risk of injury to the Hook ends lowered. The free end 54 of the eyelet 53 forming rod 52 runs downwards and obliquely against the front 10 'of the post 10. The top of the free end 54 forms the slope 5.

The grid panel 20 is hooked into the hook 3. The dimensioning of the hook 3 is such that the respective front horizontal bar 2 of the grid panel 20 on the Sloping and at the same time the opposite rear horizontal bar 2 on the front 10 'of the post 10 abuts before the horizontal bars 2.2 on the Lie on top of the attached leg 3 '.

The free end 54 of the eyelet 53 is a little elastic relocatable to the outside, so that when a vertical is applied downward force on the grid panel 20 the respective front horizontal bar 2 on the slope 5 while slightly pushing the free end 54 forward slides until the support on the leg 3 'reached is. The grid panel 20 is then with its horizontal bars 2.2 between that formed by the vertical bars 51 Front 10 'of the post 10 resilient and free of play tense.

This tension position is in the embodiment by one on at least one of the superimposed ones Hook 3 attached holding element 55.56 fixed, which one the attached leg 3 'of the hook 3rd underlying U-shaped bracket 55 with threaded legs comprises, between those lying on the leg 3 ' Horizontal bars 2.2 passes through. The over the horizontal bars 2.2 reach through the protruding ends of the legs a U-profile resting on the horizontal bars 2.2 56 and are screwed there with nuts 57 (Fig. 17).

It is understood that to hold down the grate 20 in the tensioned position shown in FIGS. 15 and 16 other hold-downs already the type previously described may be in addition to Holding elements 55,56,57 can be used.

The embodiment according to FIG. 18 shows one a rectangular hollow profile existing post 10 and the grid panel 20 attached hook 3 with against the front 10 'of the post 10 and facing downwards free thighs. The grid panels 20 are with the hook 3 through appropriately positioned and dimensioned perforations 4 passed in the front 10 'of the post 10 and then pushed down. The dimensioning and arrangement the hook 3 is hit so that the free leg 3 " sit with the bevel 5 on the lower edge of the perforations, before the attached leg 3 'does so. On in this way the grid panel 20 can travel a certain distance with elastic deformation of the free leg 3 "after be shifted down to a perpendicular against the front 10 'of the post 10 directed tensioning force to bring about on the grid panel 20.
