Abstract

The present invention concerns an arrangement for improving the bearing capacity and drainage capacity of screens for floor drains, the screens 1 consisting of a metal plate 2. For this purpose, the metal plate 2 is provided with downwardly directed edge sections 3 arranged all around it, and drainage openings 4 in the metal plate 2 are also provided with downwardly directed edge sections 5 arranged all around them. <IMAGE>

Description

467 263 rinningsöppningärnas kantpartier, som inte är runtomgäende, kan därför ej heller ges eforderlig höjd för att silelementet skall fä erforderlig bärförmága och anligga endast mot golv- brunnens säte för silelementet. 467 263 the edge portions of the drain openings, which are not circumferential, can therefore also not be given the required height for the screen element shall have the required load-bearing capacity and rest only on the floor the seat of the well for the screen element.

US. A, 4 36? 142 företer ej heller runtomgäende kantpartier till nedrinningsöppningarna men uppvisar arrangemang 22, 25 som skulle medföra att, vid användning som silelement, det- samma inte skulle kunna ligga mot sätet i golvbrunnen utmed silelementets kantpartier.US. A, 4 36? 142 also does not have circumferential edge portions to the downstream openings but has arrangements 22, 25 which would mean that, when used as a screen element, the the same could not lie against the seat in the floor drain along the edge portions of the screen element.

US, A, 4 321 713 avser visserligen ett silelement vid en golvbrunn, men saknar förstvvande kantpartier runtom ned- rinningsöppningarna som konvergerar och av angiven särskild höjd.U.S. Pat. No. 4,321,713 does indeed refer to a screen element in one floor drain, but lacks atomizing edge portions around the the drain openings which converge and of specified special height.

Anordningen enligt uppfinningen med de i patentkraven angivna kännetecknande dragen, medger att exempelvis en metallplatta med en tjocklek av 1.5 mm täler en punktbelastning i mitten av över 1000 kg utan att höjas ned. Detta innebär att silen hl.a. kan användas inom områden där det förekommer tung for- donstrafik.The device according to the invention with those specified in the claims characteristic features, allows for example a metal plate with a thickness of 1.5 mm, a point load counts in the middle of over 1000 kg without being raised. This means that the strainer hl.a. can be used in areas where there is heavy traffic donstrafik.

Dessutom säkerställas god rinningsförmäga därför att silen inte kan bli sned eller uppvisar uppätriktade grader.In addition, good flowability is ensured because the strainer can not be skewed or exhibit upward degrees.

Uppfinningen skall nedan förklaras med hänvisning till bifogade ritningar pä vilka figur 1 visar undersidan av en rund sil enligt uppfinningen i perspektiv; figur 2 är ett snitt längs linjen II-II i figur 1; figur 3 visar ovansidan och nämnda sil inlagd i en mon- teringsplatta och i perspektiv; 467 265 yttre krans 8 av nedrinningsöppningar 4, exempelvis uppvi- sande ett tjugotal nedrinningsöppningar 4, ar placerad invid metallplattans 2 kantpartier 3 fördelade runt om hela silen 1. Nedrinningsöppningarna i den yttre kransen 8 förlöper i sin langdriktning i riktning från metallplattans 2 mot me- tallplattans 2 centrum 9.The invention will be explained below with reference to attached drawings on which Figure 1 shows the underside of a round screen according to the invention in perspective; Figure 2 is a section along the line II-II in Figure 1; Figure 3 shows the top and said strainer inserted in a plate and in perspective; 467 265 outer ring 8 of downflow openings 4, for example about twenty downstream openings 4 are located next to it metal edge 2 edge portions 3 distributed around the entire screen The downstream openings in the outer ring 8 run in its longitudinal direction in the direction from the metal plate 2 towards the tallplans 2 centrum 9.

En andra krans 10 av nedrinningsöppningar 4 är placerad innanför den yttre kransen 8. Denna krans 8 kan exempelvis uppvisa ett 10-tal nedrinningsöppningar 4. Nedrinningsöpp- ningarna 4 i den andra kransen 10 förlöper i sin làngdrikt- ning tvärställt i förhållande till nedrinningsöppningarna 4 i den vttre kransen 8.A second ring 10 of downflow openings 4 is placed inside the outer wreath 8. This wreath 8 can, for example have about 10 downflow openings 4. Downflow openings the rings 4 in the second ring 10 extend in their longitudinal transverse to the downstream openings 4 i the outer wreath 8.

En inre krans 11 av nedrinningsöppningarna 4 är placerad innanför den andra kransen 10. Nedrinningsöppningarna 4 i den inre kransen 11 förlöper i sin längdriktning i riktning inåt mot metallplattans 2 centrum 9. Den inre kransen 11 kan exem- pelvis uppvisa 5-10 nedrinningsöppningar 4.An inner ring 11 of the downflow openings 4 is placed inside the second ring 10. The downspouts 4 in it the inner ring 11 extends in its longitudinal direction in the inward direction towards the center 9 of the metal plate 2. The inner ring 11 can be pelvis exhibit 5-10 descent openings 4.

Genom att nedrinningsöppningarna 4 och deras kantpartier 5 är placerade på detta satt erhålles ett särskilt styvt utförande på metallplattan 2.In that the downflow openings 4 and their edge portions 5 are placed in this way a particularly rigid design is obtained on the metal plate 2.

I figur 3 och 4 visas silen 1 placerad på en därför avsedd monteringsplatta 12. Denna har en öppning 13 med en runtom- gående kant 14, som bildar säte för silen 1. Monterings- plattan har dessutom ett nedåtriktat, runtomgående kantparti 15. Detta utförande av monteringsplattan 12 uppvisar genom denna utformning en till silen 1 anpassad stvvhet.Figures 3 and 4 show the strainer 1 placed on a dedicated one mounting plate 12. This has an opening 13 with a circumferential going edge 14, which forms the seat of the strainer 1. the plate also has a downwardly directed, circumferential edge portion 15. This embodiment of the mounting plate 12 shows through this design a stiffness adapted to the screen 1.

I figur 5 visas en fvrsidig sil 16 istället för en rund sil. Även vid denna fvrsidiga sil 16 ar de yttre kantpartierna 3 nedàtriktade liksom kantpartierna 5 runt nedrinningsöpp- ningarna 4. Nedrinningsöppningarna 4 och deras kantpartier 5 överensstämmer med motsvarande delar i den runda silen 1.Figure 5 shows a front screen 16 instead of a round screen. Also with this front strainer 16 the outer edge portions 3 are downwardly as well as the edge portions 5 around the downstream opening 4. The downspouts 4 and their edge portions 5 corresponds to the corresponding parts of the round screen 1.

Claims

467 263 The lane portions of the H-J sieves are formed by the metal plate being pressed out around the downspout and traps around the outer edges of the sieves. Claims:
