A discharging element (15) is arranged with an opening portion (17) adjacent to the collecting element to discharge gases or fluids from an upper side of a grid, where the collection element and/or the discharging element includes a round or oval base surface (7). The collection element includes a cone region (9) protruded from a top face and another cone region protruded from the bottom surface.

Description

The invention relates to a floor grate with a bottom and a walk-top, from which protrudes at least one anti-slip agent in the form of a survey element, according to the preamble of claim 1 protection.

Floor grates of the type discussed here are known from the prior art. Such floor grids allow the simple and rapid formation of floors, walk-in steps, steps and platforms, especially in scaffolding, in workshop and hall construction, with a production of different materials, especially steel or plastic, is possible. The use of a floor grate in workshops or similar industrial areas allows, inter alia, the establishment of a floor in an intermediate layer, wherein in an installation level arranged below technical equipment, suction, collecting devices, etc. can be arranged.

In order to ensure a sufficient slip resistance on the most smooth grates especially in the occurrence of moisture, some grates are sometimes provided with anti-slip agents in the form of protrusions that protrude from the surface of the grate. In the case of the prior art, the elevation elements designed as anti-slip means are usually provided via corresponding deep-drawing or press-in processes, in particular by the Bottom formed in the direction of the top of the bottom grate, so that the elevation elements due to their exposed arrangement relative to the surrounding top of the bottom grate allow a stable, non-slip kick.

In addition, due to the protruding from the top of the arrangement of anti-slip means, the use of such floor gratings as temporary drip pans in particular for oils or similar liquids possible, so that they can not penetrate to the usually arranged below installation level. Liquids accumulate between the survey elements and can then be disposed of. Due to the elevation elements is prevented that a person who runs on the bottom grid comes into contact with the liquid.

A disadvantage, however, has been found in these mostly integrally formed on the top of the bottom grate and protruding from this anti-slip means that a reliable slip resistance and especially anti-slip effect is not guaranteed.

Especially for garages, this surefootedness is defined in the professional association's BGR 157 regulations. Also regulated here are maximum elevations, distances between the individual anti-slip center and in particular the requirements that are placed on the slip resistance classes of the above-mentioned floor grids.

In addition to the requirements of the above-mentioned rule, however, floor gratings, especially for workshops, must meet even more requirements. Thus, it is sometimes necessary to install in the bottom area suction to suck in particular sinking vapors and similar gases. Such devices are particularly problematic in combination with the previously mentioned need for fluid retention devices to prevent the ingress of fluids into any underlying soil layers. This of course also applies to falling Kleintelle, such as screws, nuts and accessories.

From the DE 10 2006 016 646 A1 is a bottom grate with an improved skid resistance known, especially in the workshop a good Applicability and leads to a simpler and cheaper manufacturability.

The object of the present invention is to provide an alternative floor grate, which has a more convenient accessibility, ease of manufacture and, moreover, an improved removal of gases and fluids from the top of the bottom grate.

To solve this problem, a floor grate with the features of the protection claim 1 is proposed.

Accordingly, the bottom grid has a bottom side and a walkable top side, from which at least one anti-slip means in the form of an elevation element protrudes. The bottom grate is characterized in that at least one outflow element serving for discharging gases or fluids from the top side is arranged with at least one opening region adjacent to the elevation element.

An essential point of the invention is therefore that the elevation element achieves an optimal anti-slip effect, while at the same time the drainage element ensures an improved discharge of gases or fluids, whereby the slip resistance is increased. Characterized in that the drainage element is used exclusively for the discharge of gases or Fuiden and consequently does not rise above the top, a more comfortable accessibility of the bottom grid is achieved, since only the bump element comes into contact with the foot of a person walking on the floor grid. So over the top of the floor grate so only the elevation elements stand out, which effectively act anti-slip, while the entire raised footprint is reduced, so that there is no unpleasant and painful impressions in the sole area.

Preferably, the elevation element and / or the drainage element has a substantially round or oval base surface. Base area is here understood to mean the area enclosed by the elevation element in the plane of the floor grate. Such a form of the elevation element allows a very simple production by means of oval, round or similar rotationally symmetrical press punches, which are pressed against the underside of the bottom grid or against the top to make the drainage element. In addition, such collection and drainage elements also facilitate the cleaning of the floor grids, since no particular dirt particles catching undercuts.

Preferably, the elevation element and / or the drainage element at least partially encloses a geometry of a hemisphere, a parabola, a truncated cone or a similar rotationally symmetrical shape. Such a shape facilitates the production by means of appropriate ram, which are pressed against the bottom or the top of the bottom grate to produce the bump elements and the drainage elements. By appropriate choice of the outer geometry of the survey element can also influence the anti-slip effect are taken; This relates in particular to an enlargement or reduction of the opening area.

Particularly preferred is a variant in which the drainage element has a first cone region which protrudes from the underside. Accordingly, the bumping member may also have a second cone portion protruding from the top. The conical area is particularly easy to produce and granted by the funnel shape on the one hand an optimal drainage function of the drainage element and on the other hand, an optimal slip-inhibiting function of the elevation element. Since the cone region has substantially a round basic shape and a flattened end surface facing away from the top side of the bottom grid, the raised areas do not press painfully into the foot. Of course, other than forms may be provided, which also prevent such impressions in the foot. For example, in another embodiment, a bump element may have a plurality of wing portions protruding over the top.

The elevation element and / or the drainage element, in particular the first and / or the second cone region, can at least partially enclose an opening region. The drainage element necessarily has an opening region and, in the simplest embodiment, can be designed as such. The drainage element then only consists of an opening region which establishes a fluid connection between the upper side and the lower side of the bottom grate and thus serves as a suction opening for gases or fluids which have sunk to the grate. In this way, especially for the workshop area applicable safety regulations. The elevation element does not necessarily have an opening area. However, this increases the amount of fluid or gas that can be discharged from the top.

The elevation element and / or the drainage element may be formed as a bend, embossing or punching on the top or the bottom of the bottom grid. Basically relief-like embossments are preferred, which protrude from the surface of the floor grate. In a bump element that is punched out of the bottom grid, the punched edges form relatively sharp anti-slip edges that significantly enhance the anti-slip action of the particular anti-slip agent.

Preferably, the elevation element and / or the drainage element are formed integrally with the bottom grid. As previously mentioned, the elevation element and / or the drainage element is preferably made by bottoming, stamping or punching, or a combination of several of these steps. Of course, it would instead also be possible to secure the elevation element and / or the drainage element as independent components on or on the floor grid.

Preferably, in the elevation element and / or the drainage element, in particular in the first and / or in the second cone region, the opening region is formed in the form of a central hole. In this case, the center hole may be formed substantially coaxially to the central axis of the elevation element or the drainage element. This has the advantage, in particular in connection with the round, oval and rotationally symmetrical shape of the base of the elevation element, that the elevation element has the same effect in each load direction parallel to the surface of the bottom grid.

Preferably, the diameter of the center hole or the opening area of the elevation element or of the drainage element is substantially one third times the diameter of the base area of the elevation element or of the drainage element. In this case, the diameter of the opening region of the elevation element or of the drainage element is preferably between 0.4 cm and 1.0 cm, in particular 0.7 cm. Such an embodiment corresponds in particular to the statutory provisions as defined in BGR 157. In addition, such a trained Bumping element for the foot is not uncomfortable and also prevents the penetration of small parts through the opening areas. Furthermore, such a drainage element allows an optimal gas and / or liquid discharge from the top.

Preferably, a plurality of elevation elements at specific distances from each other are formed as punctiform elevation elements on the bottom grid. The distance between two elevation elements and / or between two outflow elements and / or between a elevation element and a drainage element preferably corresponds substantially to 0.5 to 2 times the diameter of the base of a survey element or a drainage element, in particular of 1-times the diameter. In this way, a particularly non-slip and very stable construction is also achieved.

The bottom grid is preferably made of an aluminum sheet, resulting in a significantly reduced weight and a simple and inexpensive production of the floor grate. Due to the embodiment of the survey elements according to the invention, the bottom grid can accommodate very high loads despite the softer material.

A bottom grid preferably has a plurality of elevation elements which are arranged in rows, which in turn alternate with rows of a plurality of drainage elements. In this case, the rows of the elevation elements and the rows of diverting elements are preferably arranged offset from one another such that a drainage element is in each case arranged between two elevation elements and a elevation element in each case between two outflow elements. As a result of this symmetrical arrangement in rows, in addition to an optimum distribution of the elevation and outflow elements, improved removal of gas or fluid from the top side is achieved. However, it is also conceivable to provide rows of alternating elevation and outflow elements.

The FIG. 1 shows a detailed view of an upper side of a floor grate 1 according to the invention with a walk-top 3. The walk-top 3 has a plurality of anti-slip means in the form of elevation elements 5, which in the embodiment according to FIG. 1 arranged in rows. The elevation elements 5 are formed integrally with the bottom grid 1 and protrude from the top 3.

In the embodiment according to FIG. 1 the elevation element 5 has a substantially round base surface 7. Basically, the elevation member 5 may be formed in various ways to develop an effective anti-slip effect. In the present embodiment, the elevation element 5 has a rotationally symmetrical shape, namely the shape of a truncated cone and thus a cone portion 9, which protrudes over the top 3 and the side wall with the top 3 forms an angle. This angle can be for example between 45 ° and 70 °.

The cone region 9 has an end region 11 which delimits an opening region 13 which is formed in the elevation element 5 in the form of a center hole, which is preferably arranged coaxially to the central axis M of the cone region 13. While the cone portion 9 serves as an anti-slip means, the opening portion 13 for discharging a gas or a fluid from the top 3 of the bottom shelf 1 is provided. However, as already explained, the elevation element 5 does not necessarily have an opening area 13.

The elevation element 5 can be produced, for example, by an embossing stamp which is placed on the bottom grid 1, which is preferably formed as an aluminum sheet, or with another suitable tool.

The FIG. 1 makes it clear that adjacent to a survey element 5 each a discharge element 15 is arranged, which has an opening portion 17. The drainage element 15 may be formed in the simplest embodiment as a hole in the bottom grid 1, which has been punched, for example, in an aluminum sheet. Particularly simple is the production of the drainage elements 15, even if the same tool can be used, which was used for the production of the elevation elements 5. In the exemplary embodiment shown here, the elevation elements 5 and the outflow elements 15 are therefore identical, with the difference that the outflow elements 15 protrude from an underside 19 of the bottom grid 1, as in FIG FIG. 2 is shown, while the elevation elements 5 protrude from the top 3. The drainage elements 15 and the elevation elements 5 thus protrude from opposite sides of the floor grate 1. Like the elevation element 5, therefore, the outflow element 15 also has a substantially round base surface 20.

The drainage element 15 is consequently also formed by a rotationally symmetrical body which has been produced, for example, by an embossing stamp which is placed on the upper side 3 of the floor grid 1. In this way, the drainage element 15 is formed by a cone region 21, which is referred to as "second cone region" for distinction, while the cone region 9 of the elevation element 5 is referred to below as the "first cone region". When viewed from the top side 3, the drainage element 15 thus has a funnel shape (see FIG FIG. 1 ), so that on the upper side 3 of the bottom grate 1 existing gas or fluid can be directed particularly effectively to the bottom 19 and from there, for example, in a collecting container for disposal.

The size, in particular the diameter dM of the opening area 17 or of the center hole of the drainage element 15 is chosen such that mechanical parts, such as screws or the like, do not reach an optionally existing drain. It is particularly advantageous if the diameter dM of Opening portion 17 is substantially 1/3 of the diameter dGF of the base of the drainage element. It is particularly advantageous if the diameter dM of the opening region is between 0.4 and 1 cm, but preferably 0.7 cm. According to the above-mentioned values, the diameter of the opening area 13 of a bump element 5 can also be formed.

The drainage element 15 has no elevation area which extends over the upper side 3, but is formed planar with the upper side 3. It is used exclusively for the discharge of gas and / or fluid which has accumulated on the upper side 3 of the bottom grate 1. A drainage element 15 thus serves as a supplementary element to the elevation element 5, the main function of which is the anti-slip effect for a person walking on the floor grate 1. If the elevation element 5 an opening portion 13, as in the FIG. 1 shown, it serves in a secondary function at the same time for discharging fluids or gases from the upper side 3 of the bottom grate. 1

As already in the FIG. 1 can be seen, the bottom grate 1 a plurality of elevation elements 5 and a plurality of drainage elements 15. The exemplary arrangement in rows of the elevation elements 5 and the drainage elements 15 is particularly good in the FIG. 3 recognizable. In the embodiment shown, a plurality of elevation elements 5 are arranged in a row which extends over the entire length L of the bottom grid 1. Accordingly, a plurality of drainage elements 15 are arranged in a row, which also extends substantially over the entire length L of the bottom grid 1.

Like in the FIG. 3 is shown, alternate in the width direction B rows 23 with elevation elements 5 and rows 25 with drainage elements 15 from. Between two rows 23 with elevation elements 5, a row 25 with outflow elements 15 is consequently arranged in each case. In this case, the rows 23 and 25 are arranged offset in relation to one another in the longitudinal direction L such that in each case one drainage element 15 is arranged between two elevation elements 5 and one elevation element 5 in each case between two drainage elements 15. It is understood that the above-described arrangement of the rows in the longitudinal direction L and in the width direction B may be reversed.

Characterized in that two rows 23 is interrupted with elevation elements 5 in each case by a row 25 with drainage elements 15, the number of protruding over the top 3 elements is significantly reduced, whereby the projecting over the top 3 total area significantly reduced. As a result, the bottom grille 1 is a whole lot more comfortable for a person going over the bottom grate 1 and in particular a person standing on the bottom grate 1.

The drainage elements 15, which serve exclusively for the removal of gases or fluids from the upper side 3 of the floor grate 1, in addition to the reduction of the surface protruding on the top 3 also allow a significant improvement in the removal of gases and / or fluids from the top 3 to the Bottom 19 of the bottom grate 1 and from there in particular in a suitable collecting container. This is particularly important in the workshop area, where wastewater must be disposed of in an environmentally sound manner. But also for steps or the like walkable floors, it is generally of particular importance that to reduce a risk of slipping existing fluids are derived as quickly and effectively from the top 3 of a floor grate 1. The combination of bump elements which exhibit an anti-slip effect, with drainage elements which are provided exclusively for the removal of gases or fluids from the upper side 3 of the bottom grid 1, is therefore particularly advantageous. However, it is also crucial that a uniform, in particular symmetrical distribution of the elevation elements and the drainage elements over the entire upper side 3 of the bottom grate 1 is provided. The in the FIGS. 3 and 4 shown arrangement of the elevation elements 5 and the drainage elements 15 in rows is particularly suitable for this, which alternate along the width B of the bottom grid.

In principle, however, it is also conceivable to provide alternately a bump element 5 and a drain element 15 in a row extending in the longitudinal direction L. Two adjacent rows of the aforementioned type could then always be formed complementary to one another, ie a discharge element of a second row would always be arranged next to a collection element 5 of a first row. Decisive overall is the area-wide, alternating and preferably symmetrical arrangement of elevation elements 5 and outflow elements 15 over the entire upper side 3 of a bottom grid 1.

The number of provided elevation elements 5 and drainage elements 15 depends in addition to the areal size of the bottom grid 1, which results from the width B times the length L of the bottom grid 1, and the diameter of the base 7 and 20 of the elevation elements and the drainage elements and the Distance between them. The distance a between two elevation elements or between two drainage elements or between a elevation element and a drainage element can be, for example, 0.5 to 2 times the diameter dGF of the base area of an elevation element or a drainage element. The distance a is calculated between the bases of the elevation elements and the drainage elements.

In the in FIG. 4 As shown embodiment of a modular bottom grid 1, comprises a single module, ie a bottom grate 1, two rows 23 of 22 each elevation elements 5 and two rows 25 each with 22 drainage elements 15 which are arranged alternately in the width direction B. As said, this number depends on several factors and especially on the size of the floor grid 1, which may vary depending on the application, for example for stairs, workshop floors and especially for repair pits.

The floor grates 1 are preferably modular, so that therefore several floor grates 1 can be laid side by side for any desired different applications and in particular can be connected to one another. The in FIG. 4 Floor grid 1 shown is divided into three subregions 27a, 27b and 27c, which are arranged one behind the other in the width direction B and each separated by an elongated slot 29. Starting from the upper side 3 and beyond the underside 19 also extend in the slots 29 longitudinal webs, which increase the stability of the bottom grille 1 total. In this way, a bottom grate 1 have a larger width B and thus have a larger total area, so that the laying of several floor grates 1 can go much faster and easier to a larger total area.

The FIG. 5 Finally, an application example of the floor gratings 1 according to the invention is shown. The floor gratings 1 are, as in FIG FIG. 5 can be seen, laid in several areas of a repair pit 31 for motor vehicles. On the one hand, the floor grates 1 are laterally over the actual repair pit 31 arranged a catch basin for frequently occurring in the workshop area environmentally harmful wastewater. Furthermore, the floor grates 1 are used as steps that allow access to the interior of the repair pit 31. Finally, the floor grates 1 come as a bath covering the repair pit 31 used. In each of these applications, the length and width of the bottom grid 1 may differ. Decisive in each case is that in each area of the repair pit 31, the elevation elements 5 ensure a good surefootedness of a person located on the floor grate 1 and the drainage elements 15 also for a quick and effective dissipation of existing on the top 3 of the bottom grate 1 Law or fluids ,

Overall, the present invention therefore provides a particularly advantageous floor grid, which combines advantageously a good and comfortable sure-footedness with an effective gas and liquid discharge.
