Definitions

• the invention relates to a cover grate according to the preamble of
• Cover grates are known from DE 1 659 147 A or DE 1 966 875 U, in which longitudinal members are mounted with U-shaped cross-section with their legs in slots, which are located in cross members. The side members protrude above the cross members. The slip resistance of such cover grates is not sufficient.
• the invention is based on the object, a cover grate of the type mentioned in such a way that with a simple construction improved slip resistance is guaranteed.
• a cover grille for covering shafts, gutters or similar structures comprising edge rails, with the edge rails connected cross member of sheet metal sections and connected to the cross members longitudinal beams.
• the longitudinal members are secured to the cross members such that upper tread surfaces of the side members sunk or flush at least to tread portions of upper edges of the cross member.
• This very simple construction causes the tread portions of the cross member, which in turn are made of sheet metal sections, form a non-slip surface, wherein the side members may in turn be formed so that there is no danger of getting caught (eg with narrow heels) given is.
• the longitudinal members preferably have substantially U-shaped cross-sections, with their legs are secured in the cross members. This can ensure a high stability while increasing the above-mentioned security against snagging of thin heels.
• the edge rails preferably have slots in which ends of the
• edge rails are designed as sheet-hollow profiles, which saves material and weight, but is still very stable.
• the cross members have slots for receiving the legs of the side members, wherein these slots are formed such that the legs are inserted into these slots. Again, a high stability is obtained with simple design measures.
• the ends of the cross member are preferably bent within the edge rails such that the cross member are attached to the edge rails. It can be made a stable attachment so only due to deformation, welding is not necessary.
• the cross members preferably have abutment portions in front of their ends in such a way that the ends can be inserted into the edge rails in a defined insertion depth. This achieves an exact shape and dimensioning.
• the edge rails preferably have bearing surfaces for laying on corresponding sections of the structures and lower edges of the ends of the cross members are shaped so that they rest on the inner surfaces of the bearing surfaces. This achieves high load stability.
• the tread portions of the cross member have opposite rounded
• retaining clips which are connected for securing the cover grates in the building with the edge rails. This ensures a simple but sufficiently stable installation of the grating on a building.
• the retaining clips preferably have upper
• the edge rails also have downwardly projecting floor elements, which are designed for insertion into corresponding recesses in the building and to prevent longitudinal displacement of the cover against the building. So these floor elements can be made very easily.
• the edge rails have outside access openings in such a way that the ends of the cross member are accessible from the outside for tools for connecting the cross member to the edge rails.

• Fig. 7 is a view similar to that of FIG. 5, wherein one of
• Edge rails and several of the side members and the cross member for better clarity of the structural situation are omitted.
• edge rails 10, 10 ⁇ are provided, which are interconnected by cross member 20.
• the cross member 20 have ends 23, 23 ⁇ , which stuck in slots 11 of the edge rails 10, 10 ⁇ .
• the cross members 20 in turn have slots 24 in which legs 32, 32 are pressed ⁇ of longitudinal members 30, which have a U-shaped cross section (such as an inverted U).
• tread portions 21, are portions of the upper edge 22 of each cross member, above upper treads 31 of the side members out, as can be seen in particular in Fig. 4.
• This ensures that the cross member 20 and its upper edges 22nd form a very non-slip surface of the cover with the tread portions 21.
• it is ensured by the longitudinal members 30 and their upper treads 31 that even with very narrow steps a "break-in" in the drainage openings can hardly happen.
• the cross member 20 further have at the between each two longitudinal members upwardly projecting tread portions 21 engagement corners 27, which also when the tread portions 21 is substantially flush with the upper
• Treads 31 of the longitudinal members 30 extend, still show a slip-resistant effect, since the legs 32, 32 ⁇ in their transition regions 33, 33 ⁇ to the upper tread 31 are rounded and thus a certain cavity is formed, in which an elastic shoe sole penetrate and with the engagement corners 27 "hang" can.
• the ends 23, 23 are inserted ⁇ of the cross member 20 in the slots 11 of the edge rails 10, 10 ⁇ .
• These edge rails 10, 10 ⁇ are in turn bent as a partially closed hollow body, that a lower support surface 12 is formed, with which the edge rails 10, 10 ⁇ on the building (there on a frame) rest.
• These bearing surfaces 12 in the interior of the edge rail 10, 10 ⁇ opposite inner surfaces 13 are formed, on which in turn rest in the mounted state lower edges 26 of the cross member 20 and the ends 23, 23 ⁇ . This provides maximum stability
• the edge rails 10, 10 ⁇ have outside access openings 16, 16 ⁇ , over which by means of a tool, the ends 23, 23 ⁇ of the cross member 20 can be bent so that the cross member 20 in the edge rails 10, 10 are fixed ⁇ . This contributes further that the cross member 20
• Stop sections 25 have, with which the cross member 10, 10 ⁇ stand up at the edges of the slots 11, so that when bending the ends 23, 23 ⁇ a wobble-free fit of the cross member 20 in the edge rails 10, 10 ⁇ is guaranteed.
• edge rails 10, 10 have ⁇ openings 14 (see Fig. 7), in which retaining clips 40 can be used with upper spring portions 41, each having an engagement projection 43.
• the edge rails 10, 10 ⁇ further have floor elements 15, see Figs. 2, 3 and 4, which engage in corresponding recesses of the building, so that a longitudinal displacement of the grate on the building can be reliably prevented.
