Description

The invention is directed to a privacy protection element which is suitable for shielding an accident and / or construction site on or along a road or highway, comprising a flexible flat body with a plurality of fastening eyes or other fastening means for attachment to a frame-like support element, which optionally with od a filling of intersecting rods od. Like. Is provided

To prevent the unimpeded intrusion of people fences are to be built at accident sites, but also on road construction sites or other areas to be shielded along roads.

It is not only important that access is denied to unauthorized persons, but also, if possible, an insight into the protected area. Such is undesirable in some cases; in particular accident sites on highways and other roads curious people should be kept away, so that on the one hand the rescue personnel undisturbed can pursue his work, and on the other hand, the drivers of passing vehicles are not distracted, because it is precisely through this distraction that it is not uncommon to serious consequences. The same applies to construction sites along highways, where also threatens a distraction of passing people.

Although it is known to od for other purposes of building fences or the like. With advertising messages to install. On the one hand, however, this has the disadvantage that such films are not safe enough in the event of accidents to withstand the often dangerous environmental influences - escaping chemicals, etc. On the other hand, in order for such a fence to be held under tension, its area must be slightly smaller than the area of the fence itself. Therefore, it can whose area is not completely covered; especially at the joints, where two adjacent construction fence fields are interlocked or otherwise connected to each other, more or less large gaps remain, which on the one hand give the view of the area behind it. This would lead, for example, in the shielding of accidents only to an insufficient result, because curious persons then try to catch just through these gaps, a glimpse of the scene of the accident.

From the disadvantages of the prior art described results in the invention initiating problem to form a generic privacy element such that it can also be used to shield accidents or construction sites, etc., on highways and other roads.

The solution to this problem is achieved in a generic privacy screen element in that the flexible flat body consists of a flame-retardant material, in particular of a material from one of the fire classes A, B or C according to EN-13501-1.

On the one hand, at least for a certain period of time, a source of fire possibly occurring in the area of an accident site can be kept away from the passing traffic. In addition, it is fat shown that correspondingly heat-resistant materials often also have better resistance to adverse environmental influences at all, so for example. Also against leaking acids or other toxins.

The invention recommends that the flexible flat body made of a material at least from the building material class B1 according to DIN 4102-1, or with a better fire behavior. Such materials are also suitable for the purpose of the invention for the above reasons.

Furthermore, it has been proven that the flexible flat body consists of a woven or knitted fabric or a ribbon knit. Such materials have better resistance than pure films.

The flexible flat body may consist of an air- and / or wind-permeable material, preferably of an uncoated fabric or knit or ribbon knit. As a result, when used at the roadside, it offers a lower attack surface to the wind of vehicles, so that such a shield is less in vibration than an air-impermeable material.

According to the invention, it is further provided that the flexible flat body consists of an uncoated net knit or fabric, in particular with a weight per unit area of 100 g / m ² to 200 g / m ² . Such a low weight facilitates, inter alia, the transport to an accident site.

When the flexible flat body is woven or knitted from synthetic fiber yarn, it obtains increased resistance according to mechanical and chemical external influences.

It is particularly advisable to use for the flexible flat body, a woven or knitted fabric or a knit fabric made of polyethylene, preferably a woven or knitted fabric or a ribbon knit of a polyethylene yarn or a polyethylene flat yarn, in particular a woven or knitted fabric or a knitwear of a HDPE Polyethylene yarn or a HDPE polyethylene flat yarn.

By one or more lateral connecting elements for connecting directly adjacent flat body are provided in the two lateral regions of the flat body, a seamless connection is made possible between adjacent privacy elements, thus both denied any insight on a protected terrain and on the other hand Draft or the like. Keep away. Another effect is that the visible front side of several such privacy screens can be used as a common area for presenting information, and then this information can extend across the joints of the fence areas or other supporting elements. By lateral Vebindungselemente in addition to an immediate contact or overlap nor a connection between the adjacent screen elements is made so that neither a wind or gust can open up a gap.

It has proved to be favorable that the lateral connecting elements are designed for a positive engagement with corresponding connecting elements on an immediately adjacent flat body. A positive connection is the safest way to make a reliable connection, because the interlocking elements can not be opened by accident or by the wind or by a gust of wind.

The invention can be further developed in such a way that regions of the lateral connecting elements which form a positive connection are arranged on at least one flat side of the flat body. As a result, a flat joining of adjacent screening elements is favored, which serves the strength of the connection.

Further advantages result from the fact that arranged at the same height, forming a form-fitting regions of lateral connecting elements in the region of the opposite side edges of the flat body are arranged on different flat sides of the flat body. This results in overlapping areas at the joints, whereby the opacity is optimized.

The lateral connecting elements on the mutually opposite lateral regions of the flat body should be designed as mutual counterparts in order to be able to make a direct positive connection, preferably without the use of further aids they cords od. Like. Form-fitting compounds require neither special chemical substances or physical effects and work therefore largely independent of temperature fluctuations, rain or siönstigen environmental influences.

The invention can be further developed by continuous, lateral connecting elements on the mutually opposite lateral regions of the flat body, which extend continuously over the entire height of the flat body or at least one or more, contiguous areas, each covering at least a quarter of the height of the flat body , or which cover at least one third of the height of the flat body, or which cover at least half the height of the flat body. In about vertical, elongated elements an exact match of the height is not required, so that on the one hand terrain bumps can be compensated and on the other hand, the relative position of a privacy element relative to the support element in question, such as fence, scaffolding od. Like. Not exactly must be complied with.

The lateral connection elements on the mutually opposite lateral regions of the flat body can be designed as Velcro counterparts to one another. These can also be connected to each other, even if they are at slightly staggered heights, but still overlap each other at least partially in the vertical direction.

On the other hand, it is quite conceivable to provide discontinuous lateral connecting elements on the mutually opposite lateral regions of the flat body, which extends over neither the entire height of the flat body nor over one or more contiguous areas which cover more than a quarter of the height of the flat body, or which cover more than one tenth of the height of the flat body. In the simplest case, this may be eyelets, which may possibly be enclosed by a respective metallic ring, so that a connecting means such as, for example, a cord can be threaded through such eyelets.

If corresponding discontinuous connecting elements are arranged at the same height, or at the same height with respect to an upper and / or lower edge of the flat body, a connection without the use of further connecting aids is also possible.

For example, lateral discontinuous connecting elements may be formed on the mutually opposite lateral regions of the flat body as a pushbutton counterparts to each other. These can be clipped together in a few simple steps, but if necessary, they can be detached from each other again.

According to the invention, it is preferred that the flat bodies of two directly applied privacy screens applied to a construction fence or the like overlap each other along their lateral edges. In this way, a complete opacity can be achieved.

The invention allows a development to the effect that the horizontal width of the flat body is equal to or preferably greater than the horizontal width of a fence element or equal to or preferably greater than the horizontal width of a fence element together with that one supporting post element. Because - as the invention further provides - serve the lateral Verbindungsgelemente mainly only for connection to an adjacent screen element, and not to determine the actual screen element itself od with a construction fence or other supporting scaffolding or the like. these fasteners can, however, a Comply larger distance to the relevant side edge, so be offset to the center of the relevant flat body out.

Since the screening elements according to the invention od for attachment to load-bearing elements such as fences, scaffolding od. Like. The flat body may consist of a flexible material, preferably of a textile fabric. It can therefore be rolled up or folded in an unused state to save space.

Furthermore, there is the possibility that the flat body consists of an air- and / or wind-permeable material, preferably of a fabric. By such, wind-permeable, design, such a flat body can dry quickly, for example after a rain. In addition, this reduces the wind pressure, so that a load-bearing construction fence threatens not fall over, but without passing gusts to a substantial extent.

By lateral attachment eyelets or other lateral fastening means relative to the lateral connecting elements to the center of the flat body out or offset, a determination on the frame of a construction fence od. Like. Possible, while laterally projecting areas od to the adjacent fence field. Like. Rich and so bridge a gap between them.

Another design rule states that lateral attachment eyelets or other lateral attachment means are arranged on one or more strips, which are arranged on a flat side of the flat body and extending parallel to each side edge of the flat body, but from this have a distance. Such a bar can be penetrated by eyelets, without injuring the flat body itself.

Preferably, at least one lateral strip runs along both, opposite side edges of the flat body Fixing eyelets or other fastening means, wherein all strips of a flat body are located on a common flat side of the same.

Such lateral strips with eyelets or other fastening means can be attached to the flat body and connected to that, for example sewn. As a result, fastening or holding forces of a supporting fence, scaffolding od. Like. Are introduced directly into the flat body.

The invention provides that lateral strips are formed with eyelets or other fastening means by a strip of a textile material which is sewn to the flat body, in particular along one or both longitudinal edges of the strip. Such a linear connection has a maximum of stability.

Another measure for improving the structure according to the invention is that lateral strips with eyelets or other fastening means are formed by a strip of a textile material, which is once handled and thus double-layered. A double-layered strip is thicker and thus also stronger and stiffer and better suited for attachment.

The invention can be further perfected by the fact that the folding edge of a side bar with eyelets or other fastening means, along which it is folded over, extends in the longitudinal direction. Thus, the two layers are connected over their entire length.

By both longitudinal edges of a two-ply strip with eyelets or other fastening means are all connected to the relevant flat body, preferably sewn, so once each per layer or on each longitudinal edge each once, results in a maximum loadable connection.

In the context of a first embodiment, two longitudinal edges of a two-ply strip with fastening eyes or other fastening means are both sewn together with the respective flat body, in particular with a common seam. The associated workload is minimal.

On the other hand, there is also the possibility that two longitudinal edges of a two-ply strip are bent apart with eyelets or other fastening means and are each connected separately from each other by different seams with the relevant flat body. Such a structure has the advantage that the ground plane of such a bar is orientated in a force-free state approximately at right angles to the ground plane of the flat body and the eyelets arranged therein are thus easily accessible from both sides, there, for example, a fastening cable od. Like. Threading therethrough ,

In the region of the upper and / or lower edge of the flat body further, upper and / or lower eyelets or other, upper and / or lower attachment means for fixing od to a construction fence. Like. Are arranged, with which the flat body in addition to the upper and / or anchoring lower transverse struts of a supporting frame.

On the other hand, the invention prefers that connecting elements are present neither in the region of the upper edge nor in the region of the lower edge of the flat body, except in the region of the respective corners of the flat body. Such an embodiment follows from the consideration that the height of a single flat body corresponds approximately to the height of a fence and thus extends approximately completely over the entire height of a supporting fence, so that neither above nor below another flat body can be arranged, to which a Connection would be made.

The invention recommends that at least one side of the flat body is printed with neither a pictorial representation nor with any other pattern, but is held monochrome, so that the vorbeifließende traffic is not distracted.

Adjacent support elements may be connectable to one another in their upper regions, in particular by means of connecting means which are complementary to one another and are arranged on the two vertical posts. As a result, on the one hand stabilize the individual support elements of the entire barrier each other, and the risk of tipping over is further reduced, which is particularly important because of the risk of further accidents. On the other hand, a gap between two support elements cross-strip of the flat fabric are engaged behind and thereby stabilized.

Finally, it is the teaching of the invention that connecting means between adjacent support elements comprise a fixed to a vertical post eyelet on the one hand and a cross-hook element on the other vertical post on the other hand. If such an eyelet has a horizontal plane, while the nose of a hook element in the vertical direction, such support elements can be connected in its upper region with each other, simultaneously with the common insertion into the floor-standing feet.

According to the invention it is further provided that the distance between two protruding from a common base sleeves - which are preferably offset transversely to its longitudinal extent against each other - the sum of the distance of the center of an eyelet from its vertical post plus the distance of a hook nose from the vertical post corresponds, and preferably also the width of the horizontal extension of a laterally projecting on a vertical edge of the fabric over the local eyelet strip. By thus feet, support elements and Bespannnung matched, many stringed support elements can be strung together without a gaze gap.

A plate-shaped foot has the advantage that it can be accidentally rolled over by a car tire, which is particularly important if, for example, at a narrowed by an accident roadway a driver is not concentrated enough and the screen according to the invention comes too close. Before the vehicle strikes the screen, first a vehicle tire will roll over the base facing the driving track and thus signal to the driver with a perceptible blow that he now comes too close to the screen before something actually happens. If the driver then reacts quickly enough, he can avert greater damage to his vehicle.

Due to the friction-enhancing coating on its underside, a pedestal defies any tendency to shift relative to the ground, which is particularly important when used on highways or along roads to shield an accident site, to avoid that such a privacy fence too far in the Lane shifted into it and could possibly hinder the local traffic flow.

A non-slip floor covering attached to the underside of a pedestal should contain natural and / or synthetic rubber. A rather soft material can better adapt to bumps and will therefore find support on a road surface rather than a harder material.

The invention recommends that the natural and / or synthetic rubber of a friction-increasing coating on the underside of a base is mixed with sulfur and vulcanized. As a result, the mechanical stress capacity of the material is further improved, which is the case od even in a rather rough operation on a construction site. Like. Does not take damage.

Furthermore, carbon black and / or zinc oxide and / or silicon dioxide and / or chalk and / or kaolin and / or antioxidants may be added to the natural and / or synthetic rubber of a friction-increasing coating on the underside of a base, preferably in a total amount of up to to 20% by weight or above. These substances give the friction-increasing coating particularly preferred properties.

It is within the scope of the invention that an attached to the underside of a stand, the anti-slip rubber covering is made, especially hard rubber. Especially hard rubber can carry a greater weight without a significant deformation.

Thus, in particular lateral forces can be introduced as optimally as possible in a substrate, the elongated plate should be at least partially provided on its underside with a friction-increasing coating, such as hard rubber. Since the ground will be mostly a road surface, especially asphalt, this is for example such materials into consideration, as they are used for car tires. The goal here should be the highest possible slip resistance, in other words a high static friction coefficient.

Another measure to increase the skid resistance is to provide at least one friction-increasing profile on the underside of the elongated plate, for example with mutually parallel and / or intersecting, groove-shaped depressions. It makes sense to select for this purpose those areas which are designed as preferred footprint areas and thus normally have direct contact with the ground or with the road surface, for example floor coverings made of an anti-slip material arranged on the underside of the board.

In a further development of this inventive concept, the invention provides that the elongated plate has two raised end regions arranged on its underside in the region of its front ends, and an intermediate region arranged therebetween, on the other hand set back upwards. These end-side areas have the maximum mutual distance and thus offer the highest possible tipping safety, which is why they are best suited for the best possible stability. By having these two end regions lower than the central region located therebetween, it is ensured even on slightly uneven ground that exactly these end regions have contact with the ground.

For the stability has proven optimal training of the invention, wherein the elongated plate has a flat bottom with two in the region of its front ends attached thereto, preferably downwardly projecting heels of an elastic material such as hard rubber, the undersides are profiled.

The invention further provides that on the elongated plate one or more upwardly projecting sleeves are provided with a vertical longitudinal axis for insertion of each of a vertical support post of a frame-shaped support member. The use of multiple sleeves on a common plate has the advantage that multiple support posts can be anchored to a single stand. This in turn offers the possibility to divide the support structure for a continuous screen in individual, prefabricated segments, which can then be transported in ready assembled state and placed with a few simple steps. Preferably, each segment of the screen wall or the supporting structure extends from one base to an adjacent base.

In particular, a quadruple arrangement of the sleeves provides some leeway as to how a pedestal can be used. Although, in the normal case, the longitudinal axis of the stand will be aligned approximately perpendicular to the course of the screen, in order to ensure optimum stability; exceptionally, at special bottlenecks, a single pedestal could be used once parallel to the screen, so that it does not protrude into the narrowed lane.

It has proved to be favorable that the elongated plate has a rectangular base. This offers the advantage that support elements extending transversely thereto experience sufficient lateral support even against wind gusts. For example, the plate may be more than twice as long as it is wide, preferably more than three times as long as wide, more preferably more than four times as long as wide, or even five times as long as wide or more than five times as long.

On the other hand, the invention recommends that the length of one, several or all upwardly projecting sleeves is at least twice as large as the thickness of the elongated plate of the respective stand, for example, at least four times as large as the thickness of the elongated plate, preferably at least six times as large as the thickness of the elongate plate, in particular at least eight times as large as the thickness of the elongated plate. As a result, an inserted support post experiences a good lateral support.

The thickness of the plate may preferably be 8 mm or more, preferably 10 mm or more, more preferably 12 mm or more. By a higher thickness of the plate, this not only gets a higher stiffness, but also a higher weight, which has a positive effect on the stability of the support structure.

The four upwardly projecting sleeves should have equal lengths, and / or same inner diameters. As a result, each support post can optionally be plugged into any sleeve, depending on the local conditions. In particular, it is thus also possible to realize T or even X-shaped courses of the viewing screen, where then three or even four supporting elements meet on a stand.

It is within the scope of the invention that the four upwardly projecting sleeves are arranged close to each other, preferably at or near the center of the elongate plate. In this case, between two support elements inserted in different sleeves of the same base there remains only a comparatively narrow gap which, on the one hand, hardly allows for a view, and on the other hand can easily be covered by a flap of opaque material. When placed at or near the center of the elongated plate, the center of gravity of the inserted support post is above the center of the pedestal, and this can provide maximum stability against tilting to the respective support elements.

In order for the four upwardly projecting sleeves to be arranged particularly close to each other, the invention proposes to arrange these at the corners of a quadrangle, preferably at the corners of a square. In such a positioning of the sleeves can be realized minimum mutual distances. Although it could be in the middle of the square another sleeve; However, the invention recommends to dispense with such a central sleeve to minimize the mutual distance between the four sleeves can.

Another peculiarity of the invention is that a diagonal of the square or square is arranged in the longitudinal direction of the elongated plate, the other diagonal transverse to it. Although each support post can be inserted into any sleeve; but is preferred at only two each other at one Stand encountered support post occupancy of the sleeves such that the two located near the longitudinal sides of the stand sleeves are used and the stand itself is approximately aligned so that its longitudinal axis approximately follows the course of the bisectors between the two anchored there support elements; if they extend in a common alignment line, the longitudinal axis of the pedestal points as perpendicular as possible to that line.

The elongated plate may be provided below the sleeves, each with a recess which preferably corresponds in its cross-sectional area of the clear inner cross-section of a sleeve. As a result, for example, moisture that runs down along the support posts does not remain in the sleeves during rain, but leaves those at the respective lower recess in the panel. This prevents potential contamination as well as rust.

Further advantages result from the fact that the elongated plate and / or the sleeves are made of metal, preferably of iron or steel. On the one hand, such a material offers the highest degree of stability and, on the other hand, also supplies a not inconsiderable weight, which improves the stability.

One measure to protect the elongate plate and / or the sleeves from corrosion is to galvanize them. Of course, an anticorrosive paint may be applied instead, but generally provides only reduced corrosion resistance.

The invention recommends that the sleeves are connected to the elongated plate, preferably welded, soldered or glued. As a result, tilting moments and / or lateral forces introduced in particular by the support posts into the sleeves can be reliably diverted into the base.

In order to simplify the construction and dismantling of the visor according to the invention as much as possible, the elongated plate should have one, two or more carrying handles.

Due to the increased weight of a base, the invention recommends to form the (the) carrying handle (s) as a U-shaped bracket with two short legs, which are connected by a longer central web, so that the central web can be grasped by one hand, while the Give both shorter thighs security against slipping. Especially in view of the traffic flowing past an accident site, a high grip security is important.

Thus, after pulling out of the support posts, a person can easily and safely grab and collect the feet, at least one carrying handle should be attached to or in the top of the elongated plate, preferably welded, soldered or glued.

An optimum carrying position is favored by the fact that at least one carrying handle extends transversely to the longitudinal axis of the elongate plate. For example, a pedestal can thus be held or carried transversely with its longitudinal axis in front of the abdomen.

If a carrying handle is located in an area between the sleeves and a front end, in particular between the sleeves on the one hand and an end paragraph, a pedestal can be held with one hand, in which case the end of the used handle opposite approximately vertically depends. Thus, a strong person is able to take two feet and wear at the same time, which is preferable in ergonomic terms, because thereby the spine is loaded symmetrically, while the weight does not hang in front of the spine, but approximately in the plane The spine. Especially at a weight of, for example, four to ten kilograms per stand, this aspect is not unimportant.

Preferably, a stand of a screen according to the invention has one or more holes in the elongated plate, so that such a stand can possibly also be anchored to the ground, for example. By screwing, by means of dowels or spikes. Furthermore, so that a base could also be fixed for storage purposes, for example. On a Fixierstange.

If at least one such hole is in an area between the sleeves and a front end, preferably between the sleeves on the one hand and an end paragraph, especially between a handle and a paragraph, so there are anchoring means to be applied, ie screws, dowels, Erdspieße od Likewise easily accessible.

Another design rule states that the support elements each have at least two interconnected vertical support posts. Between two such support posts, a web of an opaque material can be optimally anchored. On the other hand, another support element with one of its support posts can be placed immediately afterwards in order to produce the most complete privacy possible.

By two such support posts are preferably permanently connected to each other, for example. By extending therebetween, connected to the support posts, in particular welded, soldered or glued, horizontally extending connecting spars, resulting in a frame-like shape of the support elements, whereby those experience a high stability.

Furthermore, frame-shaped support elements offer the possibility to provide them within the frame with a grid, whereby a web of an opaque material between the support posts or other parts of the frame is not left to itself, but - especially in the case of a Windbö - to such Can nestle lattice.

Further features, details, advantages and effects on the basis of the invention will become apparent from the following description of a preferred embodiment of the invention and from the drawing. Hereby shows:

the detail IV off Fig. 3 in an enlarged view.

In Fig. 1 is an example of the present invention, a wall-shaped screen 1 shown, which can preferably be used for shielding accidents against onlookers used.

The screen 1 comprises a support structure 2 of a plurality of support elements 3, which can be modularly combined with each other.

Each support element 3 has a frame-like shape and comprises vertical support posts 4 and horizontal connecting spars 5. Preferably, each support element 3 has the shape of a vertical rectangular frame, with a first support post 4 on the left edge and a second support post 4 on the right edge, which by an upper Connecting spar 5 and are connected by a lower connecting spar 5 with each other, preferably are inextricably linked, for example. Welded together, soldered or glued.

Furthermore, such a frame-shaped support element 3 within the frame spanned by the vertical support posts 4 and the horizontal connecting bars 5 still have a filling, for example. From a kind of mat or braid of preferably perpendicularly crossing metal wires, which preferably together and / or with the support posts 4 and connecting bars 5 are connected, for example, welded, soldered or spent.

Such a support element 3 of support posts 4, connecting bars 5 and possibly a filling, for example. In the form of a mat or a braid is then covered with a web 6 of an opaque material or covered. This may be a tarpaulin, like a tarpaulin for a truck, or a fabric, for example made of linen or canvas; but it is also conceivable to use a thin plastic plate for this purpose.

As the drawing also shows, the support elements 3 rest on feet 7, of which they are held reliably.

Each foot 7 has an elongated plate 8, preferably made of metal, in particular of galvanized iron or steel. The length of the plate 8 is for example between one quarter and three quarters of the height of the opaque web 6 and the vertical distance between the upper and lower Verbindungsholm 5, preferably between one third and two thirds of the height of the opaque web 6 and the vertical distance between top and bottom connecting bar 5.

The blank of the plate 8 is preferably dimensioned such that its length is about four to six times as large as its width. The corners 9 may be rounded to minimize the risk of injury.

The plate 8 may be completely flat, whereby the production is further simplified. Since a bending step is not required, the thickness of the plate 8 can be made somewhat larger, for example 3 mm or more, preferably 5 mm or more, in particular 7 mm or more, or even 9 mm or more.

In the central region of the plate 8 are located on the upper side 10 a plurality, preferably four upwardly projecting sleeves 41 with a vertical longitudinal axis for inserting a respective vertical support post 4 of a frame-shaped support element. 3

Preferably, the sleeves 41 are all the same length and can be stumped with a front side on the top 10 and there - be fixed, for example, with an all-round weld 42.

Below each sleeve 41, the plate 8 is preferably provided with a respective recess, so that from each sleeve 41 rainwater od. Like. Can flow off at any time. However, the diameter of such a recess should be smaller than the inner diameter of the respective sleeve 41 and smaller than the outer diameter of a support post 4 to be inserted in the region of its lower end, for example at least 1 mm smaller, preferably at least 2 mm smaller, especially at least 3 mm smaller than the outer diameter of the lower end of a einzusteckenden support post 4, so that a support post 4 can not completely slip through the base 7, but on the recess 1 surrounding edge of the plate 8 rests and thus the proportionate or half the weight of the relevant support member 3 the plate acts 8 complaining and thereby counteracts unwanted tilting or slipping of the respective stand 7.

As can be seen from the drawing, all the sleeves 41 are arranged at the corners of a square, which is similar to a rhombus aligned with the plate 8, that a diagonal of this Quradrats runs parallel to a longitudinal edge 44 of the plate 8, while the other diagonal of the square extends parallel to a short end edge 45 of the plate 8.

How to get the Fig. 1 In the normal case, that is, when only two support elements 3 meet at a base 7, the longitudinal axis or a longitudinal edge 44 of the base 7 is aligned in the direction or parallel to the bisector between the coincident support elements 3, or those are oriented in a straight line of flight, perpendicular to the same line of flight. However, it would also be possible, if necessary, to align the base 7 differently, for example, parallel to the course of the screen 1, in which case, however, the mediated by the respective stand 7 stability may be reduced. A compromise is to use two immediately adjacent sleeves 41, so that the base 7 with the line of the adjacent support elements 3 includes approximately an angle of 45 °.

Like the plate 8, so the sleeves 41 may be formed or treated corrosion inhibiting, for example. Galvanized.

Further, important components of the base 7 are two coverings of an anti-slip material on its underside, preferably in the region of its two short end edges 45th

Such a slip-resistant covering should definitely have a recognizable thickness of at least a few millimeters, for example between 5 mm and 25 mm, in particular between 10 mm and 20 mm, so that with a flat or only slightly uneven ground, the middle area of the underside between the two , end coverings is lifted off the ground and the entire weight of the base 7 together with inserted support post 4 rests on the two end coverings.

The pads may, for example, consist of hard rubber, and / or of a material, as it is also used for car tires. Furthermore, a profiling can be provided, for example with grooves which preferably cross over one another, so that a grid of raised areas remains between these grooves. Other profiles are conceivable, comparable to the profile on the tread of a vehicle tire.

Another feature of a stand 7 according to the invention is that the plate 8 has one or more, preferably two continuous recesses. Such a recess may be arranged near an end-side covering, and it may preferably be used to fix the respective stand 7 on a substrate, for example by means of floor dowels.

So that a base 7 can be easily grasped, for example, in order to be set up on the spot, it also has one or more, preferably two carrying handles 43.

As Fig. 2 There are preferably two carrying handles 43 on both sides of the centrally located sleeves 41 spaced apart from those of about 2 cm to 15 cm, preferably at a distance of about 5 cm to 10 cm.

Each carrying handle 43 has an approximately U-shaped form with two side legs, which are connected to each other by a perpendicular central web.

Preferably, the side legs are shorter than the central web. The free ends of the side legs are preferably fixed to the top 10 of the plate 8, in particular welded, possibly also in local recesses inserted in the top 10 of the plate 8 and then secured, preferably welded.

Preferably, the finished assembled stand 7 (with the exception of the coverings of a slip-resistant material) is galvanized or galvanized or provided with another, corrosion-inhibiting coating.

A suitable for stringing a support member 3 for a screen element 1 web 6 is in Fig. 2 shown in a rear view, so seen from the support member 3 facing flat side.

One first recognizes the rectangular basic shape with two side edges 11, 12, an upper edge 13 and a lower edge 14.

The applied in the frame 5 state about horizontal upper and / or lower edges 13, 14 of the web flat body 6 may be reinforced, for example by sewing an additional strip of material 15 or by turning each strip-shaped portion 15 of the flat body. 6

The thus preferred two-ply strip area 15 is penetrated by a plurality of eyelet-shaped mounting holes 16, which od by means of rings. Like. Edged and thereby can be stabilized.

Through each of these attachment openings 16 may each be threaded a fastener 17 for fixing the screen element 1 to a support member 3, such as Fig. 1 lets recognize. Of course, only a single, continuous fastener 17 could be used instead.

Also, parallel to the side edges 11 of the flat body 2 extend strip-shaped elements 18, which are also penetrated by eye-shaped mounting holes 19. Also at those are Attachment means 17 can be suspended, which can be anchored to a vertical support post 4 of the support member 3.

How to get out 3 and 4 can be seen, however, the strip-shaped elements 18 are not on the main surface of the flat body 6 at. Rather, they run within an approximately vertical vertical plane. Both strip-shaped elements 18 are located on the same base side of the flat body 6, namely on the base side 20 facing the support element 3.

A strip-shaped element 18 is preferably produced from an elongate blank 21, in particular by a double-layered fold 22 extending in the longitudinal direction approximately in the middle, the two layers being connected by the folded edge 22.

In contrast, the two free longitudinal edges of the blank 21 are bent out of the plane of the strip-shaped element 18 out, by about 90 °, preferably in opposite directions. Such a folding results in two elongated, strip-shaped, single-layer tabs 23, 24, which pass over a respective bending edge 25 into the unfolded, double-layered main part 26 of the strip-shaped element 18.

The tabs 23, 24 are connected to the flat body 6, for example adhesively bonded or preferably sewn, in particular with one seam 27 extending in the longitudinal direction of the strip-shaped element 18.

The double-layered main part 26 of the strip-shaped element 18 has a multiplicity of openings 28 passing through all the layers, which are enclosed by a preferably metallic eyelet 29. Through these eyelets 29 then a separate fastener can be threaded, for example. A string, with which the flat body 6 can be fixed to the support member 3.

The two strip-shaped elements 18 are offset from the respectively adjacent side edge 11, 12 of the flat body 6 inwards, that is to the center of its area, for example by an amount of 1 cm or more, preferably by 2 cm or more, in particular by 4 cm or more, and / or by an amount of 15 cm or less, preferably by 12 cm or less, in particular by 10 cm or less.

Further, the distance between the two rigid elements 18 corresponds approximately to the width of a fence element 2 or is slightly less than the latter.

Immediately along the side edges 11, 12 further connection means 30, 31 are provided.

Such connecting means 30, 31 may be formed, for example, as mutually compatible Velcro counterparts.

Preferably, the lateral connecting means 30, 31 are each arranged on a base side 20, 32 of the flat body 6, in particular on different base sides 20, 32. This makes it possible that the two beyond the strip-shaped elements 18 respectively projecting, strip-shaped areas 33 immediately adjacent flat body 6 overlap each other, so that there is a double-layered structure. In the region of this double layer are the connecting means 30, 31, and that at the mutually facing base sides 20, 32 of both flat body 6, and thus can be connected to each other, so that no gap remains between the two flat bodies 6.

Of course, other connection means 30, 31 may be used, for example push button counterparts. In the case of such discrete connection means 30, 31, however, care must be taken that these connection means 30, 31, which are respectively to be joined together, are each at the same height and can therefore "find each other" at all.

Preferably, the flat body 6 consists of a flexible material such as, for example, a fabric, for example, from sheet or a sail cloth. Also a truck tarpaulin would be usable for it. However, preference is given to an uncoated, air or wind-permeable material which should as far as possible not be flammable.
