[0001] The invention relates to a mounting device for a radiator comprising at least one
tube, which mounting device comprises a base part to be fixed to a wall and a clamping
part to be detachably connected to the base part, which clamping part can be clamped
to the tube in use on a side remote from the base part.
[0002] With such a mounting device, as known from European patent application EP-A2-1 003
001, the clamping part comprises two shaped parts to be positioned on either side
between two tubes of a radiator. The shaped parts each have a contour designed to
conform to the diameter of the tubes of the radiator as well as to the spacing between
said tubes. The two shaped parts are interconnected by means of a sleeve. The sleeve
can then be detachably connected to the base part. A drawback of the known mounting
device is the fact that the contour of the moulded parts must be adapted in dependence
on the diameter of the tubes and the spacing between the tubes of the radiator. This
renders the mounting device unsuitable for mounting radiators comprising tubes having
mutually different diameters, with different spacings between said tubes.
[0003] The object of the invention is to provide a mounting device by means of which a radiator
comprising at least one tube can be mounted to a wall in a simple manner, which mounting
device obviates the drawbacks of the known mounting device.
[0004] This object is accomplished with the mounting device according to the invention in
that the clamping part is provided with a clamping strap which extends around the
tube in use, the ends of which clamping strap can be connected with one another.
[0005] Since the clamping strap is to be fitted round a single tube, the mounting device
does not depend on the spacing between two tubes positioned adjacently to each other.
In addition, the clamping strap can be arranged round a tube in a simple manner, irrespective
of the diameter and the shape thereof. This makes it possible to use the mounting
device with a large variety of radiators, with the clamping strap extending round
the tube readily adjusting to the shape of the tube.
[0006] It is noted that from DT-A1-24.36.331 there is known a mounting device which comprises
a strap which is passed round a column placed on a supporting surface. The strap ends
are fixedly connected to a stud bolt. A clamping piece, which is movable with respect
to said stud bolt, is pressed against a part of the radiator with a side remote from
said strap. The strap will engage the column more loosely when the clamping piece
is pressed against the radiator. Since the strap is fixedly connected to the stud
bolt with both ends, it is moreover not possible to position the strap round a tube
of the radiator, since such a tube is connected to other parts of the radiator with
both ends.
[0007] One embodiment of the mounting device according to the invention is characterized
in that the clamping strap comprises a circular central portion, strap portions extending
on either side of said central portion and ends connected to said strap portions on
a side remote from said central portion.
[0008] The circular shape of the central portion enables easy positioning of the clamping
strap round the tube, after which the ends of the strap that are connected to the
strap portions on the side remote from the central portion can be interconnected.
[0009] Another embodiment of the mounting device according to the invention is characterized
in that said ends can be moved towards each other against spring force.
[0010] In an unloaded position of the clamping strap, the ends thereof are positioned some
distance apart, which enables easy fitting of the clamping strap round the tube. When
subsequently in the ends are moved towards each other against spring force, the clamping
strap is pulled round the tube.
[0011] Yet another embodiment of the mounting device according to the invention is characterized
in that the ends of the clamping strap are provided with interlocking parts.
[0012] In this way a solid connection between the ends of the clamping strap is realised.
[0013] Yet another embodiment of the mounting device according to the invention is characterized
in that each end of the clamping strap is provided with an opening, said openings
being coaxial in the interconnected position of said ends, and a fastening element
extends through said openings.
[0014] The ends can be interconnected in a simple manner by means of said fastening element.
[0015] Yet another embodiment of the mounting device according to the invention is characterized
in that the clamping part comprises a sleeve to be connected to the base part, in
which the ends of the clamping strap can be fixed by means of said fastening element.
[0016] The ends of the clamping strap can be interconnected in a simple manner by means
of said sleeve and be drawn into the sleeve in a direction away from the tube, so
that the clamping strap is pulled tightly round the tube.

[0018] Like parts are indicated by the same numerals in the figures.
[0019] Fig. 1 shows a mounting device 1 according to the invention, which comprises a tubular
base part 2, which is provided with a horizontally extending, slotted opening 4 at
one end. The tubular base part 2 is provided with circular recesses 5 at an end remote
from the opening 4. The tubular base part 2 is provided with a threaded passage 6
between the circular recesses 5 and the opening 4. The base part 2 can be fixed to
a wall W by means of a screw 8, which is to be screwed into a plug 7. A head 9 of
the screw 8 is positioned in the base part 2, and the screw 8 extends through the
opening 4.
[0020] The mounting device 1 furthermore comprises a clamping part 3, which comprises a
tubular sleeve 10 that can be slid into the tubular base part 2 as well has a clamping
strap 11 that can be positioned in said tubular sleeve 10. The sleeve 10 comprises
a plate 12 provided with an opening 13 on a side facing towards the base part 2 (see
Fig. 7). The sleeve 10 is provided with circular recesses 14 on sides facing towards
the clamping strap 11. Said circular recesses 14 extend parallel to the circular recesses
5. As is clearly shown in Figs. 2A and 2B, the clamping strap 11 comprises a circular
central portion 15, strap portions 16, 17 extending on either side of the central
portion 15, and ends 18, 19 connected to the strap portions 16, 17 on a side remote
from the central portion 15. The ends 18, 19 extend substantially transversely to
the strap portions 16, 17. The strap portions 16, 17 can be moved towards each other
against spring force from the open position that is shown in Fig. 2A to the closed
position that is shown in Fig. 2B. In the closed position, the end 19 abuts against
the end 18 on a side remote from the central portion 15. The end 19 is provided with
an opening 20, which is bounded by an annular flange 21. In the position that is shown
in Fig. 2B, the flange 21 is positioned in an opening 22 present in the end 18. The
end 18 is provided with a square nut 23 on a side facing towards the central portion
15, an opening 24 of which nut is coaxial with the openings 20 and 22 in the ends
19 and 18 in the closed position that is shown in Fig. 2B.
[0021] The clamping part 3 furthermore comprises a bolt 26, which can be positioned in the
plate 12 of the sleeve 10, through the opening 13, from a side remote from the clamping
strap 11, and which can be brought into engagement with the nut 23 of the clamping
strap 11. The ends 18, 19 and the strap portions 16, 17 connected thereto are pulled
into the sleeve 10 in the direction indicated by the arrow P1 by screwing the bolt
26 into the nut 23. As a result, the strap portions 16, 17 come to abut against the
side walls 28, 29 of the sleeve 10, which extend parallel to each other, and the central
portion 15 is tightened round a tube in use. Once the clamping strap 11 has been connected
to the sleeve 10, the sleeve 10 is moved into the base part 2 in the direction indicated
by the arrow P1, after which the sleeve 10 is fixed in position with respect to the
base part 2 by means of a nut 30 that is to be fitted through the opening 6. The assembled
mounting device 1 is shown in Fig. 3. Fig. 4 is a view of the mounting device 1 in
assembled condition, from which the screw 8 has been left out for the sake of clarity.
A tube 31 of a radiator 32 is now present in the space bounded by the circular central
portion 15, which tube is firmly enclosed by the clamping strap 11 and connected to
the sleeve 10. The circular recesses 14 abut against the outer side of the tube 31
in this position. If the tube 31 has a relatively small diameter, for example 20 mm,
the portions of the circular central portion 15 adjacent to the strap portions 16,
17 will be pulled into the sleeve 10 as well when the nut 23 is being moved into the
sleeve 10 in the direction indicated by the arrow P1 by means of the bolt 23. If the
diameter of the tube 31 is relatively large, for example 30 mm, practically the entire
central portion will surround the tube 31. The shape of the circular recesses 14 is
preferably adapted to correspond to the diameter of the largest tube that can be mounted
by means of the mounting device 1.
[0022] Now the mounting of a radiator 32 to a wall W by means of mounting devices 1 according
to the invention will be explained in more detail with reference to Figs. 5-11.
[0023] Fig. 5 shows a radiator 32 comprising a number of tubes 31 extending parallel to
each other. The radiator 32 is preferably mounted on a wall W by means of a number
of mounting devices 1, e.g. four mounting devices 1, according to the invention. To
that end, the clamping strap 11 of each mounting device 1 is positioned opposite a
tube 31 of the radiator 32 in the open position that is shown in Fig. 2A, in such
a manner that the clamping strap 11 can be moved round the tube 31 via an opening
34 present between the ends 18, 19. The clamping strap 11 is then rotated round the
tube 31, in the direction indicated by the arrow P2, to the position that is shown
in Fig. 5. Following that, the ends 18, 19 are moved towards each other, in the directions
indicated by the arrows P3, P4, against the spring force of the clamping strap 11,
causing the clamping strap 11 to move from the open position to the closed position
(Fig. 6).
[0024] Following that, the sleeve 10 is slid over the strap portions 16, 17 of the clamping
strap 11, after which the bolt 26 is passed through the opening 13 in the plate 12
of the sleeve 10 into the aligned openings 20, 22 and 24 of the end 19, the end 18
and the nuts 23, respectively. By tightening the bolt 26, the ends 18, 19 are pulled
in the direction of the plate 12 of the sleeve 10, with the strap portions 16, 17
connected to the ends 18,19 likewise being pulled into the sleeve 10 and the central
portion 15 being pulled tightly round the tube 31. The bolt 26 is tightened until
further movement of the ends 18, 19 in the direction indicated by the arrow P1 is
no longer possible. At that point the tube 31 is firmly connected to the clamping
part 3 (see Fig. 7). This procedure is repeated until a desired number of clamping
parts 3, e.g. four clamping parts 3, are attached to the radiator 32.
[0025] An equal number of base parts 2 are fixed to a wall W before, at the same time or
after attachment of the clamping parts 3 to the radiator 32. To that end, a hole 35
is bored into the wall W, into which the plug 7 is inserted. Then the slotted opening
4 is positioned opposite the hole 35 and the screw 8 is screwed through the opening
4 into the plug 7 that has been inserted into the hole 35. The slotted configuration
of the opening 4 makes it possible to adjust the base part 2 in horizontal direction.
[0026] Subsequently, the clamping parts 3 are moved into the base parts 2 and fixed in a
desired position with respect to the base parts 2 (Fig. 10, Fig. 11) by means of a
bolt 30 that is to be passed through the opening 6.
[0027] Fig. 10 is a side view of a radiator 32 that has been mounted to a wall W by means
of mounting devices 1 according to the invention. Since the clamping strap 11 can
be fitted round a tube 31 at practically any position, a desired spacing H between
two mounting devices 1 positioned above each other can be realised in a simple manner.
Since the sleeve 10 can be moved into and out of the base part 2, the spacing A between
the radiator 32 and a wall W can be adjusted in a simple manner, and a correct mounted
position of the radiator 32 can be obtained even if the wall W is not completely level.
[0028] Since the clamping strap 11 can be fitted round any tube 31 of the radiator 32, the
spacing B between two mounting devices 1 positioned beside each other can be realised
in a simple manner (Fig. 11).
[0029] Instead of using a square nut 24 it is also possible to provide the ends 18, 19 with
threaded openings.
[0030] It is also possible to connect the sleeve 10 to the base part 2 by means of springs,
which makes it possible in a simple manner to offset any changes in the dimensions
B, H caused by expansion of the radiator upon heating thereof. The components of the
mounting device 1 may be made of a metal or of a plastic material. The components
of the mounting device 1 can easily be made in the same colour as a radiator. It is
also possible, of course, to mount other types of pipes or tubes to a wall by means
of the present mounting device.
[0031] It is also possible to provide the base part 2 with a recess near the opening 4,
in which recess an insulating plate can be placed, thus preventing any direct contact
between the wall W and the radiator 32, so that any noise occurring in the radiator
32 will not be transmitted to the wall W and be amplified in the wall.
