Field of technology
[0001] The invention concerns the connecting ring for floor drains designed for both indoor
and outdoor areas where water needs to be removed from the floor. The drain is connected
to a grate extension, or a gutter, equipped with a suitable rim for the particular
type of the final floor.
Current state of technology
[0002] The floor drain bodies are placed in concrete floors, or ceiling structures. A watertight
sealing is usually attached to the flange of the drain body. The drain body is equipped
with a grate extension, or a floor gutter with grating, designed to remove water from
the surface. The connection between the drain body and the extension, or the gutter,
is currently performed using a watertight, sealing O-ring. If water needs to be drained
from the surface of the watertight sealing, this connection is performed using a drainage
ring. A disadvantage of the O-ring connection is difficult installation and height
adjustment of the extension with respect to the drain body and the final floor level.
Further, it is difficult to check whether the O-ring is positioned correctly. Another
disadvantage is the necessity to select a single-purpose ring, i.e. either the O-ring
or the drainage ring.
[0003] EP 1 329 562 A2 describes a drain device for a ground floor. The drain unit comprises a drain opening
which represents the lower end of a pipe connector which is part of the drain unit.
The pipe connector comprises several lips which are stacked one above the other forming
a lip gasket which is integrally formed and preferably consists of elastomers.
[0004] DE 94 12 393 U1 describes a drainage device for a ground floor or a ceiling. The drainage comprises
a drainage body and an attachment piece which is attached to the top of the drainage
body. A coupling flange is located at the upper end of the drainage body. A holding
ring of the attachment piece rests on this upper end of the drainage body.
[0005] DE 90 03 409 U1 describes a drainage for draining wet rooms. Such drainage devices comprise a drainage
body which can be set into the raw ceiling and an attachment piece which can be height-adjusted
continuously and which can be set into the drainage body.
[0006] DE 87 15 924 U1 describes another drainage for draining streets and bridges which is height-adjustable.
[0007] DE 18 15 604 A1 describes a drainage body which is height-adjustable.
Subject-matter of the invention
[0008] The above mentioned disadvantages can be eliminated by the method according to claim
1 and the kit according to claim 5, in particular by the connecting ring for floor
drains, mounted between the drain body and the drain extension, following the invention
based on the fact that the connecting ring made of flexible material is fitted with
a sealing collar in its upper part on the outside. The collar has at least one opening
to allow water to pass through. On the inside, the sealing ring is fitted with a sealing
lip, and in the bottom part it is equipped with a groove for the O-ring. At the opening,
between the outer side of the ring and the inner side of the drain body, there is
a drainage groove. The sealing collar of the connecting ring overlaps the rim of the
drain body. The flexible material of the connecting ring can be an elastomer, or rubber.
[0009] The main advantage of the connecting ring according to the technical design is its
universal usage, consisting in the fact that only one type of ring can be used, either
with or without a sealing O-ring mounted in the drainage groove, and as compared to
the currently used classic O-rings, it enables simple and precise positioning of the
drainage extension or gutter in the drain body as well as height adjustment of the
drainage extension or gutter depending on the level of the final floor.
Survey of figures in the drawings
[0010] The connecting ring according to the new design is shown in the attached drawings,
where fig. 1 represents the general view of the drain with the connecting ring, fig.
2 is the detail of the connecting ring with inserted O-ring, fig. 3 shows the detail
of the connecting ring without a sealing ring, fig. 4 shows the detail of the "D-D"
opening in the connecting ring, fig. 5 is the general view of the half of the connecting
ring in partial section, indicating the opening in the collar on one side, fig. 6
is the general view of the half of the ring from above.
Invention examples
[0011] The connecting ring 1 of the floor drain is mounted between the drain body 2 and
the drainage extension 3. In its upper part on the outside, the elastomer connecting
ring 1 is fitted with a sealing collar 1.1, which overlaps the rim of the drain body
2. In the sealing collar 1.1 there are eight U-shaped openings 1.6 for water drainage.
On the inside there is a sealing lip 1.3, which fits against the drainage extension
2. In its bottom part, the connecting ring is fitted with a groove 1.5 where the O-ring
1.2 is inserted. At the openings 1.6 between the outer side of the ring 1 and the
inner side of the drain body 2 there are longitudinal pass-through drainage grooves
1.4 for the passage of water removed from the surface. If there is an O-ring 1.2 placed
in the groove 1.5, water does not pass through, as shown by the FC arrow. Otherwise,
the connecting ring 1 works as a drainage ring and water can pass through the drainage
groove 1.4 and to the drainpipe-arrow FO. Alternatively, the connecting ring 1 can
be made of rubber, or other suitable material.
[0012] The positioning of the drainage extension 3 in the drain body 2 using the connecting
ring is very easy. The connecting ring 1 is inserted into the drain body 2 as well
as the drainage extension 3, which can be rotated in the direction of arrow "R" and
moved in the direction of arrow "H" as needed until the required positioning towards
the floor is reached.
