Die Erfindung betrifft eine Bodenablaufabdeckung mit den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a floor drain cover having the features of the preamble of claim 1.

Solche Bodenablaufabdeckungen sind in eine Bodenablaufwanne eingelegt und schließen mit 5 dieser zur Bödenoberfläche eben ab.Such floor drain covers are inserted into a floor drain pan and close with 5 of this to the bottom surface from just.

Beim Ableiten von verschmutztem Wasser in den Bodenablauf setzen sich in Spalten zwischen den aufliegenden Querstäben der Bodenablaufabdeckung und den Auflagen der Bodenablaufwanne häufig Schmutzteile fest, die den Wasserablauf stören und das Herausheben der Bo-io denablaufabdeckung sehr erschweren können.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.

Aus der EP 0 337 110 B1 ist eine Bodenablaufabdeckung beschrieben, bei der die freien Enden von Querstäben, die im rechten Winkel zu einem mittleren Längsstab in gleichbleibenden Abständen angeordnet sind, mit Ausnehmungen versehen sind, die zu dem Rand des Rahmens 15 der Bodenablaufwanne hin einen Ablaufspalt bilden. Abgesehen davon, dass dies zu keiner ausreichenden Verminderung der Verschmutzungsneigung führt, ist die Herstellung dieser Bodenablaufabdeckungen aufwendig und diese müssen für jede Baulänge eines Bodenablaufes gesondert angefertigt werden. 20 Aus dem DE 297 14 723 U1 ist eine Abdeckung für eine Ablaufrinne bekannt geworden, bei der an einem Längsstab in regelmäßigen Abständen voneinander, beiderseits symmetrisch gegenüberliegend, im rechten Winkel ausragend, zu den freien Enden verjüngende und dort gründete Querstäbe aufweist, die auf Auflageschultern der Ablaufrinne aufliegen. 25 Aufgabe der Erfindung ist es die beschriebenen Nachteile zu vermeiden und eine Bodenablaufabdeckung zu schaffen, die einfach und sparsam in der Herstellung und Verlegung ist und die Verschmutzungsneigung ohne großen Aufwand stark verringert oder beseitigt.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 equal intervals, are provided with recesses, the one to the edge of the frame 15 of the floor drain pan Forming a drain gap. Apart from the fact that this does not lead to a sufficient reduction in the tendency to fouling, the production of these floor drain covers is expensive and they must be made separately for each length of a floor drain. From DE 297 14 723 U1 a cover for a gutter is known, in which on a longitudinal bar at regular intervals from each other, symmetrically opposite each other on both sides, projecting at right angles, tapering to the free ends and there established transverse bars, which on support shoulders the gutter rest. 25 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 greatly reduces the tendency to fouling easily eliminated or eliminated.

Diese Aufgabe wird bei einer Bodenablaufabdeckung nach dem Oberbegriff des Anspruches 1 30 mit den Merkmalen des kennzeichnenden Teiles des Anspruches 1 gelöst.This object is achieved in a floor drain cover according to the preamble of claim 1 30 with the features of the characterizing part of claim 1.

Die Unteransprüche betreffen besonders vorteilhafte Ausgestaltungen der Erfindung und bilden ebenso wie Anspruch 1 gleichzeitig einen Teil der Beschreibung. 35 Durch die Anordnung von langen und kurzen Querstäben an einem mittleren Längsstab ist der Abstand eines kurzen Querstabes zur Seitenwand der Bodenablaufwanne so groß, dass die Ablagerung vom Schmutz unterbleibt oder leicht entfernt werden kann, während die kurzen Querstäbe sich dennoch auf der Auflage abstützen, sodass die Belastbarkeit der Abdeckung erhalten bleibt. 40The 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 can be easily removed, while the short cross bars are still supported on the support, so the load capacity of the cover is maintained. 40

Mit der symmetrischen Anordnung der Querstäbe an dem Längsstab und der gleichbleibenden Breite der Querstäbe und der Ausnehmungen dazwischen wird ein gleichmäßiger Abfluss erreicht. 45 Mit der Anordnung der abwechselnden Tiefe der Ausnehmungen zwischen den Querstäben und zu beiden Seiten des Längsstabes wird eine gleichmäßige Anordnung der Abflußquerschnitte über die Länge der Abdeckung erreicht.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. 45 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 discharge cross sections over the length of the cover is achieved.

Dadurch verläuft der Längsstab über seine Länge nach einer Wellenlinie und mit dieser Anord-50 nung und jener der Querstäbe und der Ausnehmungen dazwischen wird bei der Herstellung der Bodenablaufabdeckungen das Ausschneiden ohne jeglichen Verschnitt und damit arbeits- und materialsparend möglich.As a result, the longitudinal bar extends along its length according to a wavy line and with this Anord-50 voltage and that of the cross bars and the recesses therebetween in the production of floor drain covers the cutting without any waste and thus labor and material saving possible.

Zur Verbesserung der Bearbeitung beim Ausschneiden einer Bodenablaufabdeckung ist die 55 Anwendung von Radien beim Übergang zwischen den geraden Stirn- und Seitenkanten mitTo improve machining when cutting out a floor drain cover, the use of radii at the transition between the straight front and side edges is included

Claims

3 AT 500 791 B1 advantageously provide a radius for high speed machining and quality of work, which for a radius is usually a part of the length, suitably one third, of a front edge. 5 Particularly useful is the design of the floor drain pan, especially in the form of a rectangular tub of suitable length, with requirements 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, placed in a floor 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 angle short transverse bars 2 and long cross bars 3 15, which are supported on flat supports 6, which are attached to the opposite longitudinal sides 7 a trough-shaped bottom drain pan 4 are. The short cross bars 2 and the long cross bars 3 are arranged alternately 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 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 that 25 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 larger 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 to the straight side edges 5 of the free ends 11 and the roots 12 of the cross bars 2 and 3 are provided with machining radii 15, each of which a 40 part, especially one third of the length the straight end edges 13, 14 of the transverse rods 2, 3 and the recesses 9,10 does not exceed. 45 1.
