  • the upper edge 81 of the bel can be located inside the area, which is surrounded by the tongues 31, 3 35.
  • centre axes of the side inlets 55, 57 are located in th same vertical plane, which in addition also contains the upper centre poi 21 of the floor drain, which highly facilitates planning and measurement installing the floor drain and the pipes connected thereto, in certain cases another position of the side inlets may be suitable.
  • the strainer II can be made with a bottom pin, matching to the depression 21 of the drain trap casing 72, and may hereby retain this casing, if the strainer is anchored e.g. by means of screws.
  • the strainer does not have to be provided with a vacuum valve.
  • the clamping of the edge of the floor carpet connected to the floor carpet do not have to be made by means of a double ring of the type shown but can b made in another way.
  • the embodiment shown and described forms a good total solution of most of the problems occurring in installing floor drains and pipings connected thereto, and in addition provides new possibilities of installing waste pipes with a floor drain, where the spa for this in different ways is restricted, at the same time as it allows f reduction of certain dimensions of the surrounding construction elements, particularly the floor structure.
  • a very advantageous feature of the floor drain according to the invention is its ability that it may without a significant loss of water the water trap, bear such short positive and negative pressures in the waste waterpipes, which sometimes occur in normal waste water systems.
  • the floor drain according to invention is advantageous compar to floor drains of a conventional design. From what has been stated above it is apparent, that several of the different details of the described floor drain can be used separately. Thus, the particular shape of the drain trap casing 75, does not presuppo that the outlet bell is arranged in a way shown, even if this is the preferred embodiment.
  • the clamping ring III and the vacuum valve IV can also be used on other floor drains. The same thing is true for the arrangement of a centre bore 21 or another guiding means, such as a centr pin, and an associated cutting tool, which is applicable to most other types of floor drains.

Abstract

Un drain d'évacuation par le sol comprend une partie principale en forme de cuvette (I) destinée à recevoir les eaux usées et comportant une trappe de drain. Une pièce de connexion de tuyau (11), à laquelle doit être connecté un tuyau d'évacuation (211-219), a la forme d'une partie de tube droite et de préférence d'une cloche droite. L'axe longitudinal (13) de ladite cloche forme avec un plan horizontal un angle alpha sensiblement supérieur à 0° et sensiblement inférieur à 90°, étant de préférence égal à 45°. Ladite cloche est en outre conçue de façon à atteindre avec sa partie la plus élevée un niveau situé au-dessus de la surface de l'eau (33) de ladite trappe du drain. L'extrémité de la partie de tube droite (11) qui est disposée à l'intérieur de la partie principale (I), a un profil (71, 73) tel que le tuyau d'évacuation des eaux usées (211-219) ayant été connecté peut être placé sur elle ou inséré dans la pièce de connexion du tuyau, pour autant que la partie la plus élevée du tuyau connecté atteint le niveau de la partie supérieure de la partie principale (1) du drain d'évacuation par le sol. La trappe dudit drain est de préférence formée par un prolongement (11b) disposé sur ladite cloche (11) et comportant un bord horizontal (73) et par un logement de trappe de drain (75). Selon la présente invention et tel qu'on le fait habituellement, une grille est prévue pour recouvrir l'ouverture du drain d'évacuation par le sol. Une soupape à vide peut être disposée dans la grille. Selon la présente invention, un anneau de type nouveau est également prévu pour fixer un tapis de sol destiné à être relié à la partie supérieure du drain d'évacuation par le sol. Celui-ci peut être pourvu d'un organe central (21) qui est situé sur la surface supérieure et autour duquel un outil de découpage peut tourner afin de découper une ouverture circulaire appropriée dans le tapis de sol.
