The invention rela-tes to a heating appara-tus of the type which
is adap-ted to be mounted as baseboard along -the walls oL -the room which i5
to be heated, said appara-tus having a housing containing channels for a
gaseous or liquid heating medium.
In known apparatuses of this type the channels for -the hea-ting
medium are tubes which may be mounted to a housing portion by suitable
mounting means. The heating medium tubes may also be mounted on the
walls of the room which is to be heated or on a carrying member which is
mounted on said wall, and another housing portion may constitute a screen
for the tubes.
The heating appara-tus according to this inven-tion is charac-terised
in -that the apparatus comprises a housing portion consis-ting oE a me-tal
profile rail having a body plate which is vertical in use, said rail being
formed with upper and lower in-tegral, inwardly facing, longitudinally
extending beads having hollow spaces which constitute supply and return
channels for the gaseous or liquid medium.
In accordance with a heating appara-tus of the type which is
adapted to be mounted as a baseboard along the walls of the room which is
to be heated, said apparatus comprising a housing portion consisting of a
proriled metal rail having a body plate providing a heat-radiating surface
which is vertical in use, said rail being formed with upper and lower integral,
inwardly facing, longitudinally extending hollow beads having hollow spaces
which constitute supply and return channels for the gaseous or liquid medium
and said housing further including internal carrying means for longitudinally
extending elec-tric cables, said carrying means comprising a profile rail
having a ladder-shaped cross-section the free ends of which engage the
opposite, arched surfaces of the beads.

By this construc-tion of -the apparatus advan-tages are obtained
during the manufac-ture and use thereof. The said housing por-tion may
be manufactured in a continuous process, preferably by extrusion of a
metal alloy, for instance an aluminium alloy, which is well adapted to be
deformed to the desired profile, and which has great heat-conducting
characteristics. By the said process of manufacture and
- 2a -
by elimination of the mounting means and mounting work for
the heating tubes a significant recluction of the manu-
facturing cos-ts is ob-tained.
As the walls in the channels which con-tain the heat-
ing medium are integral with -the housing por-tion a grea-t
heat transmission is obtained from the hea-ting medium to
the body plate and from there to the room which is to be
heated, so tha-t high efficiency is obtained.
According to an embodimen-t of -the invention the sai.d
housing portion may be formed with carrying means adapted
to engage and carry an electric heating element or a
carrying member for the latter.
Thereby the advantage is obtained -that without any
difficul-ties and greater costs an electric heating ele-
men-t can be mounted in a heating apparatus which is adap-
ted to use a gaseous or liquid heating medium, so that the
effect of the baseboard heating apparatus can be increas-
ed in desired areas, as for instance under a window, and
it may be advantageous during cer-tain seasons to use
electric heating alone during certain periods of the day
and night.
According to a special embodimen-t of the invention
the said housing portion may be formed to engage and car-
ry a carrying member for electric cables and further be
formed wi-th means for moun-ting one or more sockets for con-
necting the cables with a plug for a wire from a consump-
tion unit.

By this embodiment the heating apparatus may without
special costs be adap-ted -to constitu-te a screen for cabies
for electric heavy or low current for domestic apparatus-
es, such as lamps and television sets.
The invention will now be described in grea-ter de-
tail with reference to the accompanying drawings, in
which
Figure 1 shows a part of a housing portion in iso-
metric view and in section,
Figure Z shows a section through an embodiment of a
heating apparatus according -to the invention mounted on a
room wall,
Figure 3 shows a modified embodiment of a heating
apparatus according to the invention in side view,
Figure 4 shows a cross-section through the heating
apparatus according to Figure 3 mounted on a room wall,
Figure 5 shows the same as Figure 3 for a ~urther
modification, and
Figure 6 shows a cross-section through the appara-tus
according to Figure 5 mounted on a room wall.
The heating apparatus according to the inven-tion com-
prises, as seen in Figure 4, a housing portion 1 which is
manufactured as an integral unit, preferably by extrusion,
of a suitable metal alloy. The housing portion 1 has a
vertical body plate 2 formed with two longitudinally ex-
tending beads 3 having hollow spaces 4 which constitute
longitudinal channels.
y~
The housing portion 1 is carried by another housing
portion 5 which has a vertical body plate 6 mounted on a
room wall 7 by means of screws 8, -the portion 5 having
arched flanges 9 adapted to engage -the outer arched sur-
faces of the beads 3 by snap action.
The housing portion 1 has further an upper flange 10
extending towards the room wall 7 and a lower flange 11
which has an angular cross-section and abuts the floor 12
in the room which i8 -to be heated.
Figure 1 shows the housing portion 1 partly in iso-
metric view and partly in cross-sec-tion. During the ex-
trusion of the housing portion 1 grooves 13 are produced,
namely two at the top and one at -the bottom, and later
on series of holes are produced which are adapted to
generate a certain air circulation through the housing
portion and past -the two beads 3.
The embodiment according to Figure 1 is adapted for
heating by means of a gaseous or li~uid medium or pos-
sibly a similar cooling medium, and the baseboard is
built up of a plurality of sections of profile rails of
the type shown in Figure 1 by suitable tube coupling means
which are adapted to connect the channels 4 in adjacent
apparatus sections with each o-ther.
In the embodiment according to Figures 3 and 4 the
housing portion 1 is formed with two longitudinally ex-
tending grooves14 on the surfaces of the beads 3 facing
each other, and in said grooves plate-shaped portions 15
on a profile rail 16 having a ladder-shaped cross-section
are received, in said profile rail four spaces 17 for
electric cables 18 being provided, some of which may be
connected to sleeve sockets 19 on the outer side of the
body plate 2. ~he cables 18 which may be connected to the
mains or a source of low current, serve to deliver current
to domestic apparatuses, such as lamps, television se-ts
etc., and the housing portion l serves as carrying means
and screen for the said electric cables and for carrying
outle-ts l9 and switches for the current.
By the embodiment according -to Figure 6 the grooves
14 are used for receiving a plate-shaped electric heating
elemen-t 20 which, as shown in Figure 5, extends in zig-zag
through the longitudinal direction of the housing and
which serves -to supplement or substitute the heat effec-t
from the heating medium channels 4. On the heating ele-
ment connecting means 21 are provided adapted to connect
heating elements in two adjacent apparatus sections.
The embodiment according to Figure 2 is adapted for
heating partly by a gaseous or liquid heating medium in the
channels 4 and partly by an electric heating element 20
carried by -the housing portion l in the same way as shown
in Figure 6. Further the apparatus is adapted to carry
and screen electric cables 18 in the same ways as in the
embodiment according to Figure 4, and the cables are car-
ried by a profile rail 22 having a ladder-shaped cross-
section, the edges of said rail engaging the inner surfac-
es of the beads 3.
