Description

The invention relates to a floor drain cover having the features of the preamble of claim 1.

Such floor drain covers are inserted into a floor drain pan and close with this 5 to the ground surface from just.

When draining polluted water in the floor drain settle in columns between the horizontal bars lying on the floor drain cover and the requirements of the floor drain pan often dirt particles that interfere with the flow of water and lifting the Bo-io denablaufabdeckung very difficult.

From EP 0 337 110 B1 a floor drainage cover is described, in which the free ends of transverse bars, which are arranged at right angles to a central longitudinal bar at constant intervals, are provided with recesses which is to the edge of the frame is the bottom drain pan out Forming a drain gap. Apart from the fact that this does not lead to a sufficient improvement in the tendency to fouling, the production of these floor drain covers is complex and they must be made separately for each length of a floor drain. 20 object of the invention is to avoid the disadvantages described and to provide a floor drain cover, which is simple and economical in the production and installation and the tendency to fouling greatly reduced or eliminated without much effort.

This object is achieved in a floor drain cover according to the preamble of claim 1 25 with the features of the characterizing part of claim 1.

The subclaims relate to particularly advantageous embodiments of the invention and form as well as claim 1 at the same time a part of the description. By arranging long and short cross bars on a central longitudinal bar, the distance between a short cross bar and the side wall of the floor drain pan is so large that the deposit from the dirt is omitted or easily removed, while the short cross bars are still supported on the support, so the load capacity of the cover is maintained. 35

With the symmetrical arrangement of the cross bars on the longitudinal bar and the constant width of the transverse bars and the recesses therebetween, a uniform outflow is achieved. 40 With the arrangement of the alternating depth of the recesses between the transverse bars and on both sides of the longitudinal bar, a uniform arrangement of the outflow cross sections over the length of the cover is achieved.

As a result, the longitudinal bar extends along its length according to a wavy line and with this Anord-45 tion and that of the cross bars and the recesses therebetween in the preparation of the floor drain covers the cutting without any waste and thus labor and material saving possible.

To improve machining when cutting a floor drain cover, the use of radii in the transition between the straight end and side edges with a radius which is advantageous for high speed machining and quality of work, is usually a part of the length, conveniently one-third for a radius , a front edge amounts. Particularly useful is the design of the floor drain pan, especially in the form of a

3 AT 007 876 U1 rectangular tub of suitable length, with supports for the floor drain cover on both sides. An embodiment of the invention will be described below with reference to the drawing, in which a partial section of the floor drain cover in plan view, which is inserted into a bottom drain pan, is reproduced. A floor drain cover 1 made of metal, preferably made of stainless steel, consists of a central longitudinal bar 8 projecting from the right angles short cross bars 2 and 3 long cross bars 3o, which are supported on flat supports 6, which are attached to the opposite longitudinal sides 7 of a trough-shaped bottom drain pan 4 are. The short transverse bars 2 and the long transverse bars 3 are alternately arranged at intervals on each side of the longitudinal bar 8, wherein at the same height of the longitudinal bar 8 a short transverse bar 2 and a long transverse bar 3 lie opposite each other. The spacings of the transverse rods 2, 3 are formed by recesses 9, 10, wherein on each side of the longitudinal rod 8, a deep recess 9 is mounted on a short cross bar 2 and a shallow recess 10 on the subsequent long cross bar 3, so 20 also a deep recess 9 of a flat recess 10 at the same height of the longitudinal bar 8 opposite each other. The width of the longitudinal bar 8 between the mutual recesses 9 and 10 is always the same, whereby the longitudinal bar 8 has the shape of a wavy line. This described design of the floor drain cover 1 results in less contamination of the free ends of the transverse bars 2, 3 by greater free gap widths between them and the side walls of the bottom drain pan 4 and a uniform distribution of the drainage holes formed; Added to this is the waste-free cutting of identical drain covers by their interlocking arrangement. To improve the cutting quality and especially the cutting speed, the straight end edges 13 and 14 are provided to the straight side edges 5 of the free ends 11 and the roots 12 of the cross bars 2 and 3 with machining radii 15, each of which a 35 part, in particular a third of the length the straight end edges 13, 14 of the transverse rods 2, 3 and the recesses 9,10 does not exceed. Claims: 40 1. floor drain cover, a removable grate with a longitudinal bar, forming on both sides at equal intervals and recesses of constant width arranged cross bars, inserted into a floorable floor drain pan, with attached on opposite sides recessed flat supports for the 45 cross bars , characterized in that the bottom drain cover (1) from the middle Ren longitudinal bar (8) substantially at right angles starting, successively, alternately long cross bars (2) and short cross bars (3), the latter is still on the pads ( 6) on the opposite sides (7) of the floor drain pan (4). 50 2.
