Description

The invention relates to a privacy screen element that 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 may be provided with a filling of intersecting rods or the like is provided.

In order to avoid the unhindered entry of people, fences should be erected at accident sites, but also at road construction sites or other areas to be shielded along roads.

It is not only important that unauthorized persons are denied access, but where possible also an insight into the protected area. This is undesirable in some cases; In particular, curious people should be kept away from accident sites on motorways and other roads, so that on the one hand the rescue personnel can go about their work undisturbed, and on the other hand the drivers of passing vehicles are not distracted, because this distraction often leads to serious secondary accidents. The same applies to construction sites along motorways, where there is also a risk of distraction from the passing people.

It is known to apply foils or the like with advertising messages to construction fences for other purposes. On the one hand, however, this has the disadvantage that such films are not safe enough in the event of an accident to withstand the often dangerous environmental influences - escaping chemicals, etc. -. On the other hand, so that such a fence tarpaulin can be held under tension, its area must be slightly smaller than the area of the relevant fence field itself. As a result, it can do not completely cover its area; Especially at the joints, where two adjacent construction fence fields are hooked into each other or connected in any other way, there are more or less large gaps, which on the one hand expose the view of the area behind. For example, this would only lead to an inadequate result in the shielding of accidents, because curious people then try to catch a glimpse of the accident site through these gaps. A generic fence is from the DE 20 2014 009447 U1 known.

The disadvantages of the described prior art result in the problem initiating the invention of designing a generic screen element in such a way that it can also be used to shield accidents or construction sites, etc., on motorways and other roads.

This problem is solved in a generic privacy screen element by the features of claim 1.

On the one hand, a fire source that may occur in the area of an accident site can thereby be kept away from the flowing traffic at least for a certain period of time. In addition, it has been shown that correspondingly heat-resistant materials often also have better resistance to adverse environmental influences at all, that is to say also to escaping acids or other toxins.

The invention provides that the flexible flat body consists of a material at least from building material class B1 according to DIN 4102-1, or with better fire behavior. For the above reasons, such materials are suitable for the intended use according to the invention.

It has also proven useful that the flexible flat body consists of a woven or knitted fabric or a knitted ribbon. Such materials have a better resistance than pure foils.

The flexible flat body consists of an air and / or wind permeable material, preferably of an uncoated fabric or knitted fabric or ribbon knitted fabric. As a result, when used on the side of the road, it offers the airstream of vehicles a smaller contact surface, so that such shielding vibrates less than an air-impermeable material.

According to the invention, it is further provided that the flexible flat body consists of an uncoated mesh or woven fabric, in particular with a basis weight of 100 g / m ² to 200 g / m ² . Such a low weight facilitates, among other things, transportation to an accident site.

If the flexible flat body made of synthetic fiber yarn is woven or knitted, it will be more resistant to mechanical and chemical external influences.

According to the invention, a woven or knitted fabric or a knitted ribbon made of an HDPE polyethylene yarn or an HDPE polyethylene flat yarn is used for the flexible flat body.

By providing one or more lateral connecting elements for connecting immediately adjacent flat bodies in each of the two lateral areas of the flat body, a seamless connection is made possible between adjacent privacy shield elements, thus preventing any view of a protected area and, on the other hand, also Drafts or the like are kept away. A further effect is that the visible front side of a plurality of such screening elements can be used as a common area for presenting information, in which case this information can extend seamlessly over the joints of the fence panels or other supporting elements. Lateral connection elements create a connection between the neighboring privacy elements in addition to direct contact or overlap, so that neither a head wind nor a gust of wind can leave a gap open.

It has proven to be advantageous that the lateral connection elements for a positive interlocking engagement with corresponding connection elements are formed on an immediately adjacent flat body. A form fit is the safest method of establishing a reliable connection, since the interlocking elements cannot be opened accidentally, 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 that form a positive connection are arranged on at least one flat side of the flat body. This favors a flat joining of adjacent privacy elements, which serves the strength of the connection.

Further advantages result from the fact that regions of lateral connecting elements which are arranged at the same height and form a positive connection are arranged in the region of the mutually opposite side edges of the flat body on different flat sides of the flat body. This results in overlapping areas at the joints, which optimizes opacity.

The lateral connecting elements on the mutually opposite lateral areas of the flat body should be designed as mutual counterparts in order to be able to form a direct positive connection, preferably without using additional aids, they have cords or the like. Positive connections do not require any special chemical substances or physical effects and function therefore largely independent of temperature fluctuations, rain or other environmental influences.

The invention can be further developed by continuous, lateral connecting elements on the mutually opposite lateral areas of the flat body, which extend continuously over the entire height of the flat body or at least over one or more connected areas, each covering at least a quarter of the height of the flat body , or which cover at least a third of the height of the flat body, or which cover at least half the height of the flat body. In the case of approximately vertical, elongated elements, an exact match of the height is not necessary, so that on the one hand unevenness in the terrain can be compensated for and on the other hand the relative position of a screen element with respect to the relevant supporting element such as a fence, scaffold or the like does not have to be exactly maintained.

The lateral connecting elements on the mutually opposite lateral areas of the flat body can be designed as Velcro counterparts to one another. These can also be connected to one another, even if they are at somewhat offset heights, but at least partially overlap one another in the vertical direction.

On the other hand, it is entirely conceivable to provide discontinuous lateral connecting elements on the mutually opposite lateral regions of the flat body, which neither extend over 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 a tenth of the height of the flat body. In the simplest case, these can be eyelets, which can optionally be surrounded by a metallic ring, so that a connecting means such as a cord can then 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, then a connection is also possible without the use of further connection aids.

For example, lateral discontinuous connecting elements can be designed as push-button counterparts to one another on the opposite lateral regions of the flat body. These can be clipped together in a few simple steps, but can also be detached from each other if necessary.

According to the invention, it is preferred that the flat bodies of two directly adjacent visual protection elements applied to a building fence or the like overlap one another along their lateral edges. In this way, complete opacity can be achieved.

The invention allows a further development in that the horizontal width of the flat body is equal to or preferably greater than the horizontal width of a building fence element or equal to or preferably greater than the horizontal width of a building fence element including a supporting post element. Because - as the invention further provides - the lateral connection elements are used primarily for connection to an adjacent privacy screen element, and not for fixing the actual privacy screen element itself with a fence or other supporting structure or the like; these fasteners, however, can Maintain a greater distance from the relevant side edge, i.e. be offset towards the center of the flat body in question.

Since the visual protection elements according to the invention are intended for attachment to supporting elements such as fences, scaffolding or the like, the flat body can consist of a flexible material, preferably of a textile fabric. It can therefore be rolled up or folded to save space when not in use.

There is also the possibility that the flat body consists of an air and / or wind permeable material, preferably a fabric. Such a wind-permeable design enables such a flat body to dry quickly, for example after rain. In addition, the wind pressure is reduced, so that a load-bearing fence does not risk falling over, but without allowing gusts of wind through to a substantial extent.

By indenting or relocating lateral fastening eyelets or other lateral fastening means relative to the lateral connecting elements towards the center of the flat body, it is possible to fix them to the frame of a building fence field or the like, while laterally projecting areas extend to the adjacent fence field or the like and bridging a gap in between.

Another design specification states that lateral fastening eyelets or other lateral fastening means are arranged on one or more strips, which are arranged on a flat side of the flat body and extend parallel to a respective side edge of the flat body, but are at a distance from this. Such a bar can be penetrated by eyelets without damaging the flat body itself.

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

Such side strips with fastening eyes or other fastening means can be attached to the flat body and connected to it, for example sewn. This allows fastening or holding forces from a load-bearing fence, scaffolding or the like to be introduced directly into the flat body.

The invention provides that lateral strips with fastening eyes or other fastening means are formed by a strip made 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.

A further measure to improve the structure according to the invention is that lateral strips with fastening eyes or other fastening means are formed by a strip made of a textile material which is folded over once and is therefore double-layered. A double-layer bar is thicker and therefore also firmer and stiffer and more suitable for fastening.

The invention can further be perfected in that the folded edge of a side bar with fastening eyes or other fastening means, along which it is folded, runs in the longitudinal direction thereof. The two layers are thus connected to one another over their entire length.

Since both longitudinal edges of a double-layer strip with fastening eyes or other fastening means are all connected to the flat body in question, preferably sewn, that is to say once per layer or once on each longitudinal edge, there is a maximum load-bearing connection.

In the context of a first embodiment, two longitudinal edges of a double-layer bar with fastening eyes or other fastening means are both sewn together with the relevant flat body, in particular with a common seam. The work involved is minimal.

On the other hand, there is also the possibility that two longitudinal edges of a double-layer strip are bent apart with fastening eyes or other fastening means and are each connected to the respective flat body separately by different seams. Such a structure offers the advantage that the base plane of such a strip is oriented approximately at right angles to the base plane of the flat body in the force-free state and the eyelets arranged therein are therefore easily accessible from both sides, for example for threading a fastening rope or the like there .

In the area of the upper and / or lower edge of the flat body, further, upper and / or lower fastening eyelets or other, upper and / or lower fastening means for fixing to a building fence or the like can be arranged, with which the flat body can also be attached to the upper and / or lower cross braces of a supporting frame.

On the other hand, the invention prefers that connecting elements are present neither in the area of the upper edge nor in the area of the lower edge of the flat body, except in the area 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 field and thus extends approximately completely over the entire height of a load-bearing construction fence, so that neither another nor a flat body can be arranged above or below it Connection would be established.

The invention recommends that at least one side of the flat body is not printed with a pictorial representation or with any other pattern, but is kept in one color so that the traffic flowing past is not distracted.

Adjacent support elements can be connected to one another in their upper regions, in particular by means of complementary connecting means arranged on the two vertical posts. On the one hand, this stabilizes the individual support elements of the entire barrier, and the risk of tipping over is further reduced, which is particularly important because of the risk of further accidents. On the other hand, the strips of the two-dimensional covering that span a gap between two support elements are also gripped behind and thereby stabilized.

Finally, it corresponds to the teaching of the invention that connecting means between adjacent support elements comprise an eyelet fixed on a vertical post on the one hand and a hook element penetrating them on the other vertical post on the other hand. If such an eyelet has a horizontal plane, while the nose of a hook element points in the vertical direction, such support elements can be connected to one another in their upper region, at the same time as they are inserted together into the feet on the floor side.

According to the invention it is further provided that the distance between two sleeves protruding from a common base - which are preferably offset from one another transversely to its longitudinal extent - corresponds to the sum of the distance from the center of an eyelet from its vertical post plus the distance from a hook nose from its vertical post, and preferably also the width of the horizontal extent of a strip which projects laterally on a vertical edge of the covering over the row of eyelets there. By thus feet, support elements and If the covering is matched to one another, many covered supporting elements can be lined up without a gap in the view.

A plate-shaped foot has the advantage that it can be safely overrun by a car tire if necessary, which is particularly important if, for example, a driver is not concentrated enough at a carriageway area narrowed by an accident and comes too close to the screen according to the invention. Before the vehicle hits the front panel, a vehicle tire will first roll over the pedestal facing the roadway, signaling to the driver with a noticeable stroke that he is now getting too close to the front panel before anything actually happens. If the driver then reacts quickly enough, he can avert greater damage to his vehicle.

Due to the friction-enhancing covering on its underside, a pedestal resists any tendency to shift relative to the ground, which is particularly important when using it on motorways or along roads to shield an accident site in order to prevent such a privacy fence from extending too far into the Moved the roadway in and could possibly hinder the flow of traffic there.

A covering attached to the underside of a pedestal that increases slip resistance should contain natural and / or synthetic rubber. A rather soft material can adapt better to uneven floors and will therefore find a better grip on a road surface than a harder material.

The invention recommends that the natural and / or synthetic rubber of a friction-increasing covering on the underside of a pedestal is mixed with sulfur and vulcanized. This further improves the mechanical strength of the material, which in this case even in a rather rough operation on a construction site or the like.

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

It is within the scope of the invention that a covering which is attached to the underside of a pedestal and increases the slip resistance is made of rubber, in particular hard rubber. Hard rubber, in particular, can carry a greater weight without significant deformation.

So that in particular lateral forces can be optimally introduced into a subsurface, the elongate plate should be provided with a friction-increasing covering on its underside, at least in some areas, for example made of hard rubber. Since the subsoil will mostly be a road surface, in particular made of asphalt, materials such as those used for car tires can be used. The goal should be the highest possible slip resistance, in other words a high coefficient of static friction.

One measure according to the invention for increasing the slip resistance is to provide at least one friction-increasing profile on the underside of the elongated plate, for example with mutually parallel and / or crossing, groove-shaped depressions. It is advisable to select those areas for this which are designed as preferred contact areas and thus normally have direct contact with the ground or road surface, for example coverings made of a non-slip material arranged on the underside of the plate.

In a further development of this inventive idea, the invention provides that the elongated plate has on its underside two raised end regions arranged in the region of its front ends, and an intermediate region arranged therebetween that is set back in comparison. These end areas have the maximum mutual distance and therefore offer the highest possible stability against tipping, which is why they are best suited with regard to the best possible stability. The fact that these two end areas are lower than the middle area located between them ensures that even with a slightly uneven floor, it is precisely these end areas that are in contact with the floor.

An embodiment of the invention has proven to be optimal for the stability, the elongated plate having a flat underside with two shoulders attached to it in the region of its front ends, preferably projecting downwards, from an elastic material such as hard rubber, the undersides of which are profiled.

The invention further provides that one or more upwardly projecting sleeves with a vertical longitudinal axis are provided on the elongate plate for inserting a vertical support post of a frame-shaped support element. The use of several sleeves on a common plate has the advantage that several support posts can be anchored to a single stand. This in turn offers the possibility of being able to divide the support structure for a continuous screen wall into individual, prefabricated segments which can then be transported in the fully assembled state and set up in a few simple steps. Each segment of the screen wall or the support structure preferably extends from one base to an adjacent base.

In particular, a fourfold arrangement of the sleeves allows a certain amount of leeway in how a stand can be used. In the normal case, the longitudinal axis of the base will be aligned approximately perpendicular to the course of the screen in order to ensure optimum stability; in exceptional constrictions, however, a single stand could exceptionally be used parallel to the screen so that it does not protrude into the narrowed roadway.

It has proven to be advantageous for the elongated plate to have a rectangular base area. This offers the advantage that transverse support elements experience sufficient lateral support even against wind gusts. For example, the plate can be more than twice as long as wide, preferably it is more than three times as long as wide, in particular 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 of the upstanding sleeves is at least twice as large as the thickness of the elongated plate of the relevant stand, for example at least four times as large as the thickness of the elongated plate, preferably at least six times the thickness of the elongated plate, in particular at least eight times the thickness of the elongated plate. As a result, an inserted support post has good lateral support.

The thickness of the plate can preferably be 8 mm or more, preferably 10 mm or more, in particular 12 mm or more. A higher thickness of the plate not only gives it a higher rigidity, but also a higher weight, which has a positive effect on the stability of the support structure.

The four upstanding sleeves should have the same length and / or the same inside diameter. As a result, each support post can optionally be inserted into any sleeve, depending on the local conditions. In particular, it can also be used to realize T-shaped or even X-shaped profiles of the screen, where three or even four support elements meet on a pedestal.

It is within the scope of the invention that the four upwardly projecting sleeves are arranged close to one another, preferably at or near the center of the elongated plate. In this case, only a comparatively narrow gap remains between two support elements inserted in different sleeves of the same base, which on the one hand hardly allows a view and which on the other hand can easily be covered by a tab made 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 the relevant support elements with maximum stability against tilting.

In order that the four upwardly projecting sleeves are arranged particularly close to one another, the invention proposes to arrange them at the corners of a square, preferably at the corners of a square. With such a positioning of the sleeves, minimal mutual distances can be realized. There could be another sleeve in the middle of the square; however, the invention recommends dispensing with such a central sleeve in order to be able to minimize the mutual distance between the four sleeves.

Another special feature of the invention is that one diagonal of the square or square is arranged in the longitudinal direction of the elongated plate, the other diagonal transverse to it. Every support post can be inserted into any sleeve; however, if there are only two, preference is given to one another Supporting posts against the base occupy the sleeves in such a way that the two sleeves located near the long sides of the base are used and the base itself is aligned approximately such that its longitudinal axis roughly follows the course of the bisector between the two anchoring elements anchored there; If they extend in a common line of alignment, the longitudinal axis of the base points as perpendicular as possible to that line.

The elongate plate can be provided below the sleeves with a recess, which preferably corresponds in its cross-sectional area to the clear inner cross section of a sleeve. As a result, for example, in the case of rain, moisture running down the support posts does not remain in the sleeves, but leaves them at the respective lower recess in the plate. This prevents potential pollution, but also rust.

Further advantages result from the fact that the elongate plate and / or the sleeves consist of metal, preferably of iron or steel. On the one hand, such a material offers maximum stability and, on the other hand, it provides a not inconsiderable weight, which improves the stability.

One measure to protect the elongated plate and / or the sleeves from corrosion is to galvanize them. Of course, an anti-rust paint can also be applied instead, but this generally only provides 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 into the sleeves from the support posts can be reliably derived into the base. In order to simplify the assembly and disassembly of the screen according to the invention as much as possible, the elongate plate should have one, two or more handles.

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

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

An optimal wearing position is favored by the fact that at least one handle extends transversely to the longitudinal axis of the elongated plate. For example, a stand can be held or carried with its longitudinal axis transversely in front of the stomach.

If a 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 shoulder, a stand can also be held with only one hand, the end area opposite the handle used then hanging approximately vertically. Thus, a strong person is able to grab and carry two feet at the same time, which is also preferable from an ergonomic point of view, because this places a symmetrical load on the spine and the weight does not hang in front of the spine, but rather on a level surface The spine. Especially with With a weight of, for example, four to ten kilograms per stand, this aspect is not unimportant.

A base of a viewing panel according to the invention preferably has one or more bores in the elongated plate, so that such a base can also be anchored to the floor, if necessary, for example by screwing on, using dowels or with earth spikes. Furthermore, a base could also be fixed for storage purposes, for example on a fixing rod.

If there is at least one such bore in an area between the sleeves and an end, preferably between the sleeves on the one hand and an end shoulder, in particular between a handle and a shoulder, the anchoring means to be used there, i.e. screws, dowels, earth spikes or the like easily accessible.

Another design specification states that the support elements each have at least two vertical support posts connected to one another. A sheet of opaque material can be optimally anchored between two such support posts. On the other hand, another support element with one of its support posts can also be placed immediately afterwards in order to produce the most complete view protection possible.

Because two such support posts are preferably permanently connected to one another, for example by horizontally extending connecting bars extending between them, connected, in particular welded, soldered or glued, to the support posts, a frame-like shape of the support elements results, which gives them a high degree of stability.

Furthermore, frame-shaped support elements offer the possibility of providing them with a lattice within the frame, as a result of which a sheet of an opaque material between the support posts or other parts of the frame is not left to itself, but rather - in the case of a gust of wind - adheres to one Can nestle mesh.

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

In Fig. 1 a wall-shaped screen 1 is shown as an example of the present invention, which can preferably be used to shield accidents from onlookers.

The screen 1 comprises a support structure 2 comprising a plurality of support elements 3, which can be combined with one another in a modular manner.

Each support element 3 has a frame-like shape and comprises vertical support posts 4 and horizontal connecting bars 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 is represented by an upper one Link bar 5 and are connected to each other by a lower link bar 5, preferably are inseparable, for example welded, soldered or glued together.

Furthermore, such a frame-shaped support element 3 can also have a filling within the frame spanned by the vertical support posts 4 and the horizontal connecting bars 5, for example from a type of mat or meshwork of metal wires which preferably cross at right angles, preferably with one another and / or with the support posts 4 and connecting bars 5 are connected, for example welded, soldered or glued.

Such a support element 3 comprising support posts 4, connecting bars 5 and, if appropriate, a filling, for example in the form of a mat or a mesh, is then covered or can be covered with a web 6 made of an opaque material. This can be a tarpaulin, in the manner of 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.

As can be seen from the drawing, the support elements 3 rest on feet 7, by which they are held reliably.

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

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

The plate 8 can be completely flat, which further simplifies the manufacture. Since a bending step is not required, the thickness of the plate 8 can be chosen to be 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 area of the plate 8 there are a plurality, preferably four, upwardly projecting sleeves 41 with a vertical longitudinal axis for inserting a vertical support post 4 of a frame-shaped support element 3 on the top 10 thereof.

The sleeves 41 are preferably all of the same length and can be butt-fitted with an end face on the top 10 and fixed there - for example with a weld seam 42 running all around.

Below each sleeve 41, the plate 8 is preferably provided with a recess, so that rainwater or the like can flow out of each sleeve 41 at any time. However, the diameter of such a recess should be smaller than the inner diameter of the relevant sleeve 41 and also smaller than the outer diameter of a support post 4 to be inserted therein in the region of its lower end, for example at least 1 mm smaller, preferably at least 2 mm smaller, in particular at least 3 mm smaller than the outer diameter of the lower end of a support post 4 to be inserted, so that a support post 4 cannot slide completely through the base 7, but instead stands on the edge of the plate 8 surrounding the recess 1 and thus the proportionate or half the weight of the support element 3 in question the plate 8 acts aggravating and thereby counteracts an undesired tilting or slipping of the stand 7 in question.

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

How to Fig. 1 can be seen, in the normal case, i.e. when only two support elements 3 meet on a base 7, the longitudinal axis or a longitudinal edge 44 of the base 7 there is aligned in the direction or parallel to the bisector between the encountering support elements 3, or if those are oriented in a straight line of alignment, perpendicular to that same line of alignment. If necessary, however, it would also be possible to align the base 7 differently, for example parallel to the course of the screen 1, in which case, however, the stability imparted by the base 7 in question can be reduced. A compromise is to use two immediately adjacent sleeves 41 so that the base 7 forms an angle of approximately 45 ° with the line of the adjacent support elements 3.

Like the plate 8, the sleeves 41 can also be designed to be corrosion-resistant or treated, for example galvanized.

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

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 the middle area of the underside between the two on a flat or only slightly uneven surface , end facings is lifted off the floor and that total weight of the base 7 together with the inserted support post 4 rests on the two end facings.

The coverings can consist, for example, of hard rubber and / or of a material as is also used for car tires. Furthermore, profiling can be provided, for example with grooves which preferably cross 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 special 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 can be arranged near a covering on the end, and it can preferably be used to fix the relevant base 7 on a surface, for example by means of floor plugs.

So that a stand 7 can be easily gripped, for example to be set up on the spot, it also has one or more, preferably two handles 43.

How Fig. 2 shows, there are preferably two handles 43, on both sides of the centrally arranged sleeves 41, at a distance from those of about 2 cm to 15 cm, preferably at a distance of about 5 cm to 10 cm.

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

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

The fully assembled base 7 (with the exception of the coverings made of a non-slip material) is preferably galvanized or galvanized or provided with another, corrosion-resistant coating.

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

The rectangular basic shape with two side edges 11, 12, an upper edge 13 and a lower edge 14 can first be seen.

The upper and / or lower edges 13, 14 of the sheet flat body 6, which are approximately horizontal in the state applied to the frame 5, can be reinforced, for example by sewing on an additional material strip 15 or by turning over one strip-like section 15 of the flat body 6.

The double-layer strip area 15 preferred in this way is penetrated by a plurality of eyelet-shaped fastening openings 16 which can be framed by means of rings or the like and can thereby be stabilized.

One fastening means 17 can be threaded through each of these fastening openings 16, in order to fix the sight protection element 1 on a support element 3, such as Fig. 1 reveals. Of course, only a single, continuous fastener 17 could be used instead.

Strip-shaped elements 18 also extend parallel to the side edges 11 of the flat body 2 and are likewise penetrated by eyelet-shaped fastening openings 19. Even on those are Fastening means 17 can be suspended, which can be anchored to a vertical support post 4 of the support element 3.

How to get out 3 and 4 can be seen, however, the strip-shaped elements 18 do not rest on the main surface of the flat body 6. 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 made from an elongated blank 21, in particular formed by a double layer 22 by a fold 22 running approximately centrally in the longitudinal direction, the two layers being connected via 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, specifically by approximately 90 °, preferably in opposite directions. Such a folding results in two elongated, strip-shaped, single-layer tabs 23, 24, which each pass over a bending edge 25 into the non-folded, double-layer main part 26 of the strip-shaped element 18.

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

The double-layer main part 26 of the strip-shaped element 18 has a multiplicity of openings 28 which pass through all layers and which are each bordered by a preferably metallic eyelet 29. A separate fastening means can then be threaded through these eyelets 29, for example a cord, with which the flat body 6 can be fixed to the support element 3.

The two strip-shaped elements 18 are offset inwards from the respectively adjacent side edge 11, 12 of the flat body 6, that is to say towards the center of the surface thereof, 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.

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

Further connecting means 30, 31 are provided directly along the side edges 11, 12.

Such connecting means 30, 31 can be designed, for example, as mutually compatible Velcro strips counterparts.

The lateral connecting means 30, 31 are preferably arranged on a respective base side 20, 32 of the flat body 6, in particular on different base sides 20, 32. This makes it possible for the two strip-shaped regions 33, which protrude beyond the strip-shaped elements 18, to be directly adjacent flat bodies 6 overlap each other, so that there is a double-layer structure. The connection means 30, 31 are located in the region of this double layer, namely on the mutually facing base sides 20, 32 of both flat bodies 6, and can therefore be connected to one another so that no gap remains between the two flat bodies 6.

Of course, other connection means 30, 31 can also be used, for example push-button counterparts. In the case of such discrete connecting means 30, 31, however, care must be taken to ensure that these connecting means 30, 31 which are to be merged in each case are at the same height and can therefore “find” one another at all.
