Description

The present invention relates to a radiator according to the preamble of claim 1. It thus relates to a radiator, in particular a design radiator having a device for attachment to a mounting surface, wherein the fastening device comprises a plurality, preferably four, attachable to the mounting surface retaining elements, which are each mounted pivotably in at least one plane on the radiator. The attachment surface may preferably be formed by a wall, but also by a bottom or other carriers.

There are already numerous devices for mounting radiators on walls known. In many cases holding elements are used, which engage in recesses or cavities of the radiator. In tubular heaters engage such holding elements from the back into the spaces between the heating tubes, whereby they are visible from the front, which is particularly disadvantageous in design radiators.

A radiator with such a fastening device is from the EP 1 039 240 A2 known. In this case, the fastening device comprises fastenable on the radiator support and fastened to a wall support holder, which are linearly displaced from each other to achieve different wall spacings. The carriers are taken during assembly of the radiator between two tubes of the radiator, wherein a cross tube of the radiator is suspended in a trough of the carrier and the adjacent cross tube is brought against a receiving seat opposite the trough. The carriers engage in the spaces between the heating tubes, that the components of the fastening device located on the radiator are visible from the front of the radiator, which is disturbing, especially in design radiators. For this fastening device can also be used in curved radiators, a hinge is integrated into the carrier as a separate component, which ensures a pivoting in one plane. This means a considerable effort in the production of the fastening device and correspondingly higher production costs.

It is also known to attach to the back of the radiator holding elements, such as hooks, brackets or straps, which cooperate with appropriately trained and fastened to the wall fasteners. These holding elements are barely visible from the front of the radiator or not at all. They are firmly and immovably fixed to the radiator, usually welded. Therefore, they must be adapted from the outset to the surface shape of the mounting surface to which the radiator is to be attached. This results in a large number of different variants, which leads to considerable cost increases.

However, the retaining elements must be adapted not only to the respective mounting surface, but in particular to the shape of the radiator itself. For example, in tubular heaters with curved heating tubes depending on the radius and angle of the bend different orientations of the holding elements required to the radiator on flat mounting surfaces to be able to attach. This requires an additional effort and additional costs in the production of radiators, since the retaining elements must always be adapted to the geometry of the bend. Above all, it is a great disadvantage that it is not possible to produce a standardized basic radiator with straight heating tubes and unitary holding elements, in which the heating tubes then bent arbitrarily and the holding elements can still be used on flat mounting surface.

From the post-published WO 2004/090429 A1 a radiator according to the preamble of claim 1 is known, which is mounted on two pivotable holding elements, which serve here simultaneously as a connection device for the Heizwasserstrom. The holding elements each have a nozzle which is attached to the radiator.

From the EP 0 962 712 A2 Furthermore, a radiator is known in which the fastening device comprises at least one angle compensating piece for mounting and for mounting. This angle compensating piece is first pivotally attached thereto prior to its final connection to the radiator so that it can be pivoted in the desired direction and properly aligned. Only then the angle compensation piece is finally firmly connected to the radiator and the verschenkbarkeit thereby repealed. This solid connection is still during the production of the radiator and is preferably cohesively, for example, carried out by soldering.

The installation of such a radiator is therefore associated with the disadvantage that both the pre-assembly at the manufacturer and the final assembly at the end user is relatively expensive. At the manufacturer, the angle compensating pieces must first be attached only pivotally and then in a second step still firmly connected to the radiator. In addition, the final alignment of the angle compensation pieces must already be established and fixed by the manufacturer of the radiator. If it should turn out to the end user of the radiator that due to the local conditions of the mounting surface a different orientation of the angle compensation pieces is required, this must be used for the connection solder heated to the range of the melting temperature and cooled again after reorienting the angle compensation pieces, which a considerable effort is connected. Overall, therefore, the installation of the radiator designed very expensive and it is associated with correspondingly high manufacturing and assembly costs.

Object of the present invention is therefore to provide a structurally simple and inexpensive to produce radiator of the type mentioned above, which allows easy installation and which is easy and quick to install on differently shaped mounting surfaces and also a particularly simple and efficient production of different variants allows differently bent radiators, the fastening device is not visible from the front of the radiator.

This object is achieved by a radiator according to claim 1. Advantageous embodiments and modifications of the invention will become apparent from the dependent claims.

It is essential in the solution according to the invention that the heating element for each holding element in each case has a connecting piece on which or in which the holding element is pivotally mounted and latching held either releasably or permanently. As a result, a particularly simple and cost-effective production of the radiator is made possible. In this case, the holding elements can be fastened either releasably or permanently on the radiator. In order to obtain a particularly secure attachment of the radiator is proposed to perform the locking connection insoluble or provide additional security elements.

The solution according to the invention also means a significant simplification of the installation of the radiator and associated cost savings. In this case, a particularly great flexibility in the final assembly of the radiator is achieved, which is retained until its attachment to the mounting surface. Only in the final assembly of the radiator, the pivotally mounted holding elements are pivoted into the respectively required for this fastening position. In this case, there is no previous firm connection of the holding elements on the radiator, through which the pivoting is canceled, so that an optionally necessary readjustment of the alignment angle of the holding elements can be made particularly simple, fast and inexpensive.

A significant advantage lies in the fact that a high flexibility on the one hand with respect to the mountability of the radiator to different geometries of the mounting surface and on the other hand with respect to an optionally desired bending of the radiator or the heating pipes of the radiator is achieved.

Therefore, the manufacturing cost of the radiator are particularly low even with a variety of different bends of the radiator or the appropriate mounting surfaces.

Another significant advantage is that is created by the arrangement of a respective nozzle for each holding element from the front of the radiator not visible type of attachment. In addition, the nozzle allows a particularly simple storage of the retaining element for immediate warranty of the pivoting movement, which reduces the effort and cost in the manufacture of the radiator or its fastening device.

A particularly high flexibility can be achieved in that the holding elements are each pivotable in two mutually perpendicular planes, wherein the pivoting movements are superimposed on each other. These two levels are advantageously perpendicular to the main plane of the radiator. However, the advantages of the invention can also be achieved even with a pivoting of the holding elements in only a single plane, which is preferably perpendicular to the mounting surface and parallel to the bottom surface. In curved radiators, it is preferably at the same time the plane in which the bend of the radiator or the heating pipes runs.

It is further advantageous if the holding elements each comprise a latching region on which at least one outwardly projecting latching element is arranged, through which at least one provided on the radiator Spring element is engaged behind. The spring element can advantageously be formed by a spring ring. Also, a plurality of spring elements, such as resiliently mounted balls may be provided.

As a preferred development is proposed for this purpose that each locking portion is formed by a projection and each locking element by a collar.

As an alternative embodiment of the invention, it is proposed that the holding elements each have at least one spring element, which can be engaged behind by at least one latching element projecting on the heating element.

As a particularly advantageous embodiment is further proposed that the inside hollow neck in their free end face each have an opening through which with or without radial play the locking element or the collar and with radial play of the locking portion or the projection of a holding element in the Stub is insertable, wherein in or behind the opening at least one elastically outwardly depressible spring element, preferably a slotted spring ring, is provided, through which the latching element or the collar of a holding element latching in the interior of the nozzle is firmly held.

For a particularly stable embodiment, it is also advantageous if the nozzles are attached to the radiator, in particular to the manifolds of the radiator, preferably welded.

For radiators with two manifolds, between which a plurality of heating pipes are arranged, it is also particularly advantageous if the nozzles are arranged on the manifolds at an angle preferably of 90 ° to the ends of the heating pipe opening to the manifolds.

Furthermore, it is particularly advantageous in such radiators with curved heating tubes, when the heating tubes are bent at least in a central region, but preferably completely, in a direction perpendicular to the longitudinal axis of the manifold tubes level in which the holding elements are pivotally mounted in the nozzle.

According to a further particularly preferred embodiment of the invention it is provided that each retaining element is releasably secured to a respective receiving part, which is firmly attached to the mounting surface, in particular on a wall. It is proposed to first attach the receiving parts to the wall and then attach the holding elements to the receiving parts.

It is particularly advantageous if the receiving parts are cylindrical in shape with a recess into which the holding elements are insertable with a piston-shaped region, wherein means for locking the holding elements, in particular locking screws, are provided in the region of the recess.

The radiator 1 shown in the figures is a known tubular heater with two manifolds 2, between which a plurality of heating pipes 3 are arranged through which the heating fluid in the desired manner between the distribution pipes 2 can flow. In the FIGS. 1 and 2 is only a manifold 2 and a portion of the heating pipes 3 shown.

For fixing the radiator 1 to a wall, a fastening device 4 is provided which comprises a total of four retaining elements 5. The holding elements 5 each comprise a piston-shaped or fully cylindrical base body 6, which has a coaxially projecting projection 7 at its end facing the heating element 1, which forms the latching region. At the free end of the projections 7 each one over the entire circumference radially outwardly projecting and the detent element forming collar 8 is formed, the end face is rounded spherical segment. At the side facing away from the projection 7, the base body 6 has a conical end region with a circumferential phase 9 in order to facilitate insertion into a hollow cylindrical receiving part 10.

The radiator 1 has on its back four nozzles 11, which are welded to the manifolds 2. The stubs 11 have inside each a cavity 12, in which the collar 8 can be inserted through the projection 7 of a holding element 5 through an end opening 13.

Behind the opening 13 is located inside a slotted spring ring 14 as elastically outwardly depressible spring element whose inner diameter is smaller than the outer diameter of the collar 8 in the idle state. When pressing a retaining element 5 in a socket 11 of the spring ring 14 is pressed by the spherical end face of the collar 8 to the outside. Once the collar 8 is completely in the cavity 12, the spring ring 14 springs back inside into the annular groove in the region of the projection 7 between the collar 8 and body 6 back. In this way, a latching stop and thus easy mounting of the holding elements 5 is achieved at the nozzle 11. This locking connection is carried out insoluble. Alternatively, it can also be released with special tools to perform repair or maintenance can.

Due to the provided between the projection 7 and the inner wall of the opening 13 small game each holding element 5 is pivotally mounted in a socket 11. The pivoting is given in each case in two mutually perpendicular planes 15 and 16, which in turn are both perpendicular to the main plane of the radiator 1. The pivoting movements are freely superimposed on each other, so that a particularly variable connection possibility of the radiator 1 is given at any intermediate positions of the holding elements 5.

The nozzles 11 are arranged here on the distributor pipes 2 at an angle of 90 ° to the ends of the heating pipes 3 opening onto the distributor pipes 2. Therefore, a bending of the heating tubes 3 in a direction perpendicular to the longitudinal axis of the distributor tubes 2 extending plane can be compensated by the pivoting of the holding elements 5 in the plane parallel thereto 16.

The heating tubes 3 can be bent by an arbitrary angle up to a maximum of twice the angle by which the holding element 5 can be pivoted from its non-deflected central position to the side. In the in the FIGS. 6 and 7 illustrated example, the heating pipes 3 are bent by an angle of approximately 30 ° in de drawing plane. The holding elements 5 are also pivoted in the plane of the drawing at an angle of about 15 ° from its central position to the outside, so that the free end faces 17 of the holding elements 5 are in a common plane. In this way, a particularly efficient and cost-effective production of different types of radiator, each with differently bent heating tubes 3 can be achieved.

In the in FIG. 2 illustrated embodiment, each retaining element 5 in each case a hollow cylindrical receiving part 10 can be inserted and can be fixed therein by means of a locking screw 18. The receiving parts 10 are previously in turn mounted on the wall to which the radiator 1 is to be attached. For this purpose, they have in their voltage applied to the wall bottom surface suitable openings, for example, a slot 19 for receiving fastening screws.
