EP3428343B1 - Screen for screening of accidents and foot therefor - Google Patents

Description

The invention relates to a screen for shielding from accidents, comprising frame-shaped support elements which each have at least two interconnected, vertical support posts and are covered or can be covered with a flexible sheet made of an opaque material and are held in support feet, and on a stand for such a screen.

A generic screen is the German Offenlegungsschrift DE 196 38 361 A1 refer to. According to the invention there, a vertical stand is inserted into several holding feet, and then a fabric web is stretched between these stands. Since each support foot can only carry one stand, there are large gaps between the individual stands, which are stabilized by horizontal expansion elements. The fabric web is then hung on slot-shaped recesses in the stands. This system can be completely dismantled down to the individual components and thus stored and transported in a space-saving manner. However, a large number of handling steps are required for on-site assembly, which takes a long time.

The utility model DE 20 2014 009 447 U1 discloses a wind and / or privacy screen element for flat application to a building fence or the like, comprising a flat body with a plurality of fastening eyes or other fastening means for attachment to a building fence or the like, one or. in or on the two lateral areas of the flat body several lateral connecting elements are provided for connecting immediately adjacent flat bodies. This privacy screen element is not suitable for shielding accidents on busy roads because the wide and bulky feet are an obstacle to traffic.

The disclosure WO 2010/031122 A1 discloses a fence panel support leg of the type which is arranged to support fence panels upright on a floor surface. The support foot has a box-shaped foot block of sufficient weight and dimensions to prevent an upright fence panel from tipping over when it is mounted on the foot block and when the panel is subjected to predetermined forces normal to the expansion of the panel. There are three or more mounting brackets to hold an upright mounting post on a fence panel. The mounting receptacles are arranged in one or more groups on the foot block, each group having at least three mounting receptacles which are arranged so close to one another that the upright mounting rods of the fence panels accommodated therein maintain a predetermined distance between them. Due to the voluminous box shape, this base is also not suitable for use on busy roads.

In the patent US 5,553,648 a portable wall component is disclosed. The wall component includes a pair of vertical posts. Each post has an upper component and a lower component with a hollow opening extending therethrough. However, there is no frame-shaped support element. This cannot be replaced by the vertical posts, so that use on busy roads is also out of the question here.

The disclosure WO 2016/139486 A1 shows a stand for a temporary lock, comprising a support portion made of plastic material, on which at least one upwardly extending pin or base or at least one recess is provided for inserting a part of the lock. Instead of a frame-shaped support element and a flexible flat body, only one fencing panel is disclosed as a barrier. Since the base does not have a friction-increasing coating on its underside, it could slip into traffic and hinder it when used on a busy street.

The disadvantages of the prior art described result in the problem initiating the invention of developing a generic screen for shielding against accidents in such a way that the screen can be assembled and disassembled as quickly as possible and has the best possible stability.

The solution to this problem is achieved in that each pedestal has an elongated plate, which is provided at least in some areas with a friction-increasing coating on its underside and is designed in such a way that it can be safely rolled over by a car tire and four upwardly projecting sleeves with a vertical longitudinal axis Inserting a vertical support post of a frame-shaped support element, wherein the four upstanding sleeves are arranged at the corners of a square, one diagonal of the square is arranged in the longitudinal direction of the elongated plate, the other diagonal transverse to it.

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 touches the front panel, a vehicle tire will first roll over the pedestal facing the roadway, signaling to the driver with a noticeable blow 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-increasing coating 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 streets to shield an accident site in order to avoid that such a privacy fence shifted too far into the lane and could possibly hinder the flow of traffic there.

A plurality of 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.

A four-fold 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.

So that the four upwardly projecting sleeves are arranged particularly close to one another, they are arranged 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 support posts meeting each other on a pedestal, it is preferred that the sleeves be occupied such that the two sleeves located near the long sides of the pedestal are used and the pedestal itself is aligned approximately such that its longitudinal axis roughly corresponds to the course of the bisector between the two supporting elements anchored there follows; If they extend in a common line of alignment, the longitudinal axis of the base points as perpendicular as possible to that line.

A covering attached to the underside of a pedestal and increasing the 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 nature and / or synthetic rubber of a friction-increasing covering on the underside of a pedestal is mixed with sulfur and vulcanized. As a result, the mechanical strength of the material is further improved, which in this case is not damaged even in the case of 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 of the type that are also used for car tires can be considered. The goal should be the highest possible slip resistance, in other words a high coefficient of static friction.

Another measure to increase the slip resistance is to provide at least one friction-increasing profile on the underside of the elongated plate, for example with groove-shaped depressions that are parallel and / or intersect with one another. 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 the 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 concept, the invention provides that the elongate plate has on its underside two raised end regions arranged in the region of its front ends, and an intermediate region arranged therebetween, which is set back in comparison therewith. These end areas have the maximum mutual distance and therefore offer the highest possible stability against tipping, which is why they are best suited in terms of the best possible stability. Because these two end areas are lower than the middle area in between, Even with slightly uneven floors, it is ensured that precisely these end areas are in contact with the floor.

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

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 may 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 as large as the thickness of the elongated plate, in particular at least eight times as large as the thickness of the elongated plate. This provides an inserted support post with 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 such a 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 flap 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.

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, in particular tilting moments and / or lateral forces introduced into the sleeves by 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 that 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. With a weight of, for example, four to ten kilograms per stand, this aspect is not unimportant.

A base of a screen 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, by means of 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, a another support element with one of its support posts can be placed immediately afterwards in order to create a complete privacy screen.

Since two such support posts are preferably permanently connected to one another, for example by connecting brackets extending in between, connected to the support posts, in particular welded, soldered or glued, horizontally extending connecting bars, this results in a frame-like shape of the support elements, 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.

A sheet made of an opaque material can be clamped or anchored to a support element in that it is attached to the vertical support posts and / or to the horizontal connecting bars of a frame-shaped support element, for example by means of rings, cords, wires arranged through holes or eyes in the sheet or the like. There is also the possibility of threading a tension wire through a series of eyelets of the opaque web, which is then anchored to the support element.

The opaque web can consist of a flexible material, for example a tarpaulin material for trucks and / or a fabric, for example of linen or canvas. This can be a light material, which can save weight, so that a individual support element can be transported and erected by a maximum of two people or possibly even by a single person.

On one or both surfaces, such a track can be provided with information, for example with warning signals and / or warning colors, or with an instruction to continue carefully, etc.

In order to be able to bridge the gap to a subsequent web in such a way that there is no longer any viewing gap, the invention provides that a web has at least one overlap region in at least one area of a joint between adjacent support elements. This can, for example, follow the course of a vertical support post with a width of a few centimeters, for example five to twelve centimeters, and thus extends to an adjacent support post.

Finally, it corresponds to the teaching of the invention that an overlap area can be defined on a subsequent web by means of a Velcro connection. On the one hand, this results in a complete screen; on the other hand, a continuous surface is also obtained, which can be printed with information spanning the various support elements, for example with a message in large letters directed at the passing road users.

Furthermore, the invention is characterized by a base for a screen for shielding from accidents, with frame-shaped support elements which each have at least two interconnected vertical support posts and are covered or can be covered with a flexible sheet made of an opaque material and are held in support feet, wherein the base has an elongated plate and four sleeves projecting upward from this elongated plate with a vertical longitudinal axis for inserting a vertical support post of a frame-shaped support element. Such a stand is of central importance for a screen, since it should give it sufficient stability even in stormy weather.

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 Connecting bar 5 and are connected to one another by a lower connecting bar 5, preferably are inseparably connected to one another, for example welded, soldered or glued to one another.

Furthermore, such a frame-shaped support element 3 within the frame spanned by the vertical support posts 4 and the horizontal connecting bars 5 can also have a filling, for example made of a type of mat or mesh of metal wires that 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.

Fig. 4 shows the cut of the plate 8, after which its length is about 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 11 with a vertical longitudinal axis for inserting a vertical support post 4 of a frame-shaped support element 3 on the upper side 10 thereof.

The sleeves 11 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 12 running all around.

Below each sleeve 11, the plate 8 is preferably provided with a recess 13, so that rainwater or the like can flow out of each sleeve 11 at any time. However, the diameter of such a recess 13 should be smaller than the inner diameter of the sleeve 11 in question 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 therefore the proportionate or half the weight of the support element 3 concerned acts on the plate 8 in a weighting manner and thereby counteracts an undesired tilting or slipping of the relevant base 7.

As can be seen from the drawing, all sleeves 11 are arranged at the corners of a square, which is aligned to the plate 8 in a manner similar to a rhombus in such a way that a diagonal of this square is parallel to a longitudinal edge 14 of the plate 8, while the other diagonal of the square runs parallel to a short end edge 15 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 14 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, but the stability imparted by the base 7 in question can then be reduced. A compromise is to use two immediately adjacent sleeves 11 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 11 can also be designed to be corrosion-resistant or treated, for example galvanized.

Further, important components of the base 7 are two coverings 16 made of an anti-slip material on its underside 17, preferably in the region of its two short end edges 15.

Such a slip-resistant covering 16 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 region 18 of the underside 17 on a flat or only slightly uneven surface between the two end-facing coverings 16 is lifted off the floor and the entire weight of the base 7 including the inserted support post 4 rests on the two end-facing coverings 16.

The linings 16 can consist, for example, of hard rubber and / or of a material such as is also used for car tires. Furthermore, profiling can be provided, for example with grooves 19, which preferably cross each other, so that a grid of raised areas 20 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 21. Such a recess 21 can be arranged near an end covering 16, and it can preferably be used to fix the relevant base 7 on a surface.

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 22.

How Fig. 2 shows, there are preferably two handles 22, namely on both sides of the centrally arranged sleeves 11, at a distance from them of about 2 cm to 15 cm, preferably at a distance of about 5 cm to 10 cm.

Each handle 22 has an approximately U-shaped shape with two side legs 23 which are connected to one another by a central web 24 perpendicular thereto.

The side legs 23 are preferably shorter than the central web 24. The free ends of the side legs 23 are preferably fixed, in particular welded, to the top 10 of the plate 8, possibly also inserted into the recesses 25 in the top 10 of the plate 8 and then fastened, preferably welded on.

The fully assembled base 7 (with the exception of the pads 16 made of an anti-slip material) is preferably galvanized or galvanized or provided with another, corrosion-resistant coating.

The Fig. 1 shows as a further peculiarity that a tab-like extension 26 can be provided on a web 6 made of an opaque material along a vertical edge, which serves the purpose of covering the gap between two support posts 4 adjacent to anchored support elements 3 in the same base 7, so that the privacy screen is complete. Furthermore, a Velcro element can be arranged in the area of the free edge 27 of such a tab-like extension 26, as a counterpart to another Latv element in the area of the opposite edge 28 of the web 6 of the support element 3 concerned In the area of the free edge 27 of the tab-like extension 26, a suitable counterpart along the free edge 28 facing it, so that the joining of these Velcro elements results in a continuous screen wall, which could possibly also be printed for the transmission of messages.

The plate 8 of a pedestal 7 preferably has a length of approximately 800 mm to 1200 mm, and / or approximately a width of 100 mm to 200 mm and / or a thickness of 10 mm to 20 mm. The weight of a stand 7 according to the invention is then about 15 kg to 25 kg.
