Description
SPECIFICATION
Flexible tube for connecting a ventilating roof tile to the ventilating pipe of a building
This invention related to a flexible tube made of plastics material having spiral folds and pipe fittings positioned at its ends, one of which being provided with a socket to be connected to the pipe extension of a ventilating roof tile and the other having a spigot end to be connected to the ventilating pipe of a building.
For the purpose of venting soil pipes in buildings, ventilating ducts are being used which are usually connected to special ventilating roof tiles. Since the ventilating pipe which ends below the roof is usually offset parallel to the respective ventilating roof tile and its pipe extension, flexible tubes are being used, among others, to connect the ends of the pipes.
In a known design of this type (DE-OS. 29 29 978), a one-piece flexible tube made of plastics material provided with a pipe fitting formed at each end is being used. Such a flexible tube is designed for a certain axial offset between the ventilating pipe and the pipe extension of the ventilating roof tile. If the axial offset of the ends to be connected is larger and/or the ends are further away from each other, then the greater distance can be bridged by two or more flexible tubes. However, in order to also meet the different local conditions in the best possible way, flexible tubes of different lengths are required which entails higher expenditure for stock-keeping.
It is an object of the invention to design a flexible tube of the aforementioned type which can be used as universally as possible.
This problem is solved according to this invention in that at least one pipe fitting has at its tube-sided end a socket provided with an internal screw thread, into which the corresponding end of the flexible tube is screwed.
By connecting the flexible tube with one or two pipe fittings in this way, it is possible to use a flexible tube having a length which is also sufficient for bridging greater distances between the ventilating pipe and the ventilating roof tile. An adjustment to smaller distances can easily be made then by shortening the flexible tube. Since the shortened end of the flexible tube has just to be screwed again into the socket of the respective pipe fitting, an adjustment can also be made quickly, and one will always obtain connections having an aesthetic appearance.
According to the invention there is provided a flexible tube made of plastics material having spiral folds and pipe fittings positioned at its ends, one of which being provided with a socket to be connected to the pipe extension of a ventilating roof tile and the other having a spigot end to be connected to the ventilat
ing pipe of a building, characterised in that at
least one pipe fitting (10, 11) has at its tube
sided end a socket (1 0a, 11 a) provided with
an internal screw thread (lOb, 11 b), into
which the corresponding end of the flexible
tube (8a, 8b) is screwed.
Preferably, the two pipe fittings consist of
rigid plastics material and each of them has a
socket provided with an internal screw thread
having at least two turns. This permits a safe
and tight connection of the pipe fittings with
the pipe extension of the ventilating roof tile
and the ventilating pipe as well as between
the pipe fittings and the ends of the flexible
tube.
If the folds of the flexible tube are also
supported by a wire helix, then an especially
tension-proof connection between the pipe fitt
ing and the end of the flexible tube screwed
therein is obtained without making any addi
tional provisions necessary. Besides, the flexi
ble tube is provided thereby with a high
torsional strength which makes any undesira
ble loosening or unscrewing of one end of the flexible tube from the respective pipe fitting
more difficult after it has been assembled,
because for this it is also necessary to disen
gage at least one pipe fitting either from the
ventilating pipe or the pipe extension of the
ventilating roof tile.
There now follows a description of a parti
cular embodiment of the invention, by way of
example only, with reference to the accom
panying drawings, in which:
Figure 1 shows a partial view of the cover
ing of a pitched roof with a ventilating roof
tile and connected to its underside a flexible
tube as well as a part of a ventilating pipe
connected to the lower end thereof.
Figure 2 shows the connection of the upper
end of the flexible tube with the lower end of
a pipe extension of the ventilating roof tile
according to Fig. 1 in sectional view and on a
larger scale, and
Figure 3 shows the connection of the lower
end of the flexible tube with the upper end of
the ventilating pipe according to Fig. 1 in
sectional view and on a larger scale.
As can be seen from Fig. 1, there is pro
vided a rafter 1 to which roof battens 2 are
fixed, which beside serving to receive shaped
roof tiles 3 also serve the purpose of receiving
a special ventilating roof tile 4, preferably
made of plastics material. The ventilating roof
tile has a pipe extension 5 which is fastened
on the rafter 1 by means of a pipe clamp 6.
The underside of the ventilating roof tile 4 is
connected with a roof batten 2 by a clip 7
which provides against lift-off caused by storm
and wind.
By way of a flexible tube 8 with spiral folds
9, which is provided with pipe fittings 10, 11
at its ends, the pipe extension 5 of the
ventilating roof tile 4 is connected to a venti
lating pipe 12 leading to soil pipes of the said building, as described hereinafter in greater detail with reference to Fig. 2 and 3.
As can be seen from Fig. 2, the lower end of the pipe extension 5 of the ventilating roof tile is inserted into the pipe fitting 10, the upper part of which is formed as a socket 1 0c provided with a circular groove 1 0d to receive a sealing ring 13. The lower part of the pipe fitting has a socket 1 0a provided with an internal screw thread 1 Ob, into which the flexible tube 8 is screwed with its upper end 8a.
The flexible tube 8 consists of a blown film made of polyethylene having a thickness of approximately 0.2mm. The folds 9 of the flexible tube are supported by a wire helix 14 made of spring steel wire having a thickness of approximately 1 mm.
As can be seen from Fig. 3, the flexible tube 8 is with its lower end 8b connected to the pipe fitting 11 by way of screwing it into its socket 1 1 a which is provided with an internal screw thread 1 1 b. The lower part of the pipe fitting 11 has a spigot end 1 1 c being inserted into a socket 1 2a which is formed at the upper end of the ventilating pipe 12 and provided with a circular groove 1 2b to receive a sealing ring 15.
