Description

The invention relates an arrangement with a Radiator according to the preamble of claim 1, such as EP-A-0 386 496 is known.

Because radiators have at least end areas that are aesthetically undesirable Radiators are preferably on their side Ends, but also on their front and the upper section with textured or also plan to provide cladding panels or cladding.

These panels not only serve the purpose of a better look, but also In addition, they ensure that there is no one from the sides of the radiator Soiling or dusting of the radiator can take place.

Such panels for radiators are particularly for panel radiators their lateral edge areas required, because the panel radiators plan out There are heating plates, between which a continuous one seen from the side Gap is present. With panel radiators, however, there is still the problem that the panels are very difficult to attach to the radiator. Here there There have been numerous attempts to install such radiator covers. So are e.g. Radiator covers have been glued on. There are also radiator covers with circumferential edge areas that were manufactured with their Edge areas the welding hub or cross seam of the heating plates of the concerned Grip the radiator or plate radiator under tension. The former radiator covers have the disadvantage that the panels cannot be removed as they are glued in place while the second radiator panels have the significant disadvantage that manufacturing tolerances in both Manufacture of the panel as well as in the manufacture of the radiator in question or plate radiator often cause the panels not on Hold the panel radiator. In addition, there are all heating and Cooling processes that the radiator goes through, very considerable noise pollution and the movements caused by different thermal expansions between the panel and the radiator cause that just on the relatively sensitive area of the welding hub or the cross seam the paint surface is regularly damaged, which leads to corrosion etc.

Another attempt to address the ongoing problem of installing radiator covers Mastering consists of two pairs of brackets, the one at the top and the lower end of a lateral radiator cover by these are welded to the radiator cover. The brackets grip as in the generic prior art, towards the welding hub of heating plates of radiators or plate radiators and fix the covering in question in that the relevant pairs of clips press against the welding hubs with a certain preload and so that the cladding plate or cladding sheet hold. That kind of Fastening can compensate for small manufacturing tolerances by the welded Brackets are bent at different angles, however, require this well-known cladding a variety of steps and additional Divide. In addition, the problem also arises here that due to thermal expansion and when cooling, differential movements between the panel and the Radiators occur that lead to noise pollution on the one hand and on the other hand cause the paint on the radiator to be damaged.

With other fastening techniques, the radiator cover is over recesses on protruding parts of the radiator or a trim frame or the like. However, this causes the fairing to be relative is loosely attached to the radiator in question, so that the panel easily from Unauthorized persons can easily remove it, even with the slightest vibration rattles, noises when heating or cooling the radiator causes separate parts on the radiator and thus further manufacturing steps requires, and many more disadvantages.

It is the object of the present invention to provide an arrangement with a radiator to propose in which the disadvantages mentioned above are largely eliminated or do not occur at all; in particular, an arrangement with a radiator and a panel is proposed that are easy to manufacture and also easy to assemble or can be dismantled. Furthermore, an arrangement with a panel and a Radiator proposed that can solve the same task.

The above task is accomplished by a arrangement solved with the features listed in claim 1.

Advantageous refinements go from Sub-claims emerge.

The advantages to be achieved according to the invention consist inter alia in that the holding devices in question in a single Work step can be formed without being welded or riveted would need, or other fastening techniques would be required. The holding devices or material sections can be cut or punched out, for example, the material sections can be bent inwards so that manufacturing tolerances in the covering device according to the invention and / or balanced on the radiator can be.

The holding devices or material sections of the lining device according to the present invention can both on the lower area and on the upper area of the cladding panel, preferably a lateral cladding panel. However can the relevant holding devices on the upper and lower area, be provided in the middle and at any point, with preference being given to it is that two of the holding devices on the edge regions of the relevant cladding panel are at least substantially opposite, so that the one together with the other apply the necessary clamping force can.

Experiments have shown that a pair of Holding devices can easily be applied a holding force of about 70 to 80 kg can, so that already one of the clamp-like holding devices Force can be applied to an unauthorized or unintentional Removing the panel essentially makes it impossible.

The cladding panel has at least one of its long sides and / or High sides of a bent leg, which is, for example, about 90 ° to the plane the cladding panel is bent, or corresponding leg extensions. This allows an otherwise between the radiator and the panel cover existing gap. Furthermore, this thigh process makes it easier that Holding devices also in the immediate edge area of the cladding panel can be trained.

The cladding panel and / or the legs have recesses and / or Cutouts that, for example, protruding radiator elements, such as or return connection pipes, thermostatic valves, heating cost display devices, etc., correspond and can pick them up or let them through. An adjustment of radiator linings by correspondingly different training of such Recesses or cutouts are easily possible in terms of production technology.

At least one of the holding devices preferably faces the central axis of the Cladding panel towards its free leg, so that a corresponding clamp effect possible from the inside towards the inside of the welding hub is. Conversely, at least one of the holding devices from the Central axis of the panel have away their free leg, so that the clamp-like holding devices can grip around the welding hub from the outside, to in this way the required clamping force for holding the cladding panel to apply. Here, the holding device or the holding devices also at least partially from the leg or leg extension of the Cladding panel punched out or cut out or notched. Around selectively on the welding hub or a possible recess on the welding hub or to be able to attack the transverse seam of the radiator or panel radiator, the free leg of a holding device can have a hook-like extension. With such a design, it is not possible to cover the panel without an appropriate tool (e.g. a screwdriver) from deduct a radiator with a corresponding profile.

The free leg of the holding device advantageously has or have the free leg of the holding device has a recess so that the leg in the top view of the leg is U-shaped. This is the free leg a holding device not continuously, but has, for example, two or more webs on the clamping surface or the hook-shaped extension connect to the cladding panel. In the former case, with only one web, that is T-shaped holding device. The width of the resulting webs allows the Set the clamping force. Are not webs, but a continuous leg available, the clamping force is particularly large, and are only relatively thin webs available, the clamping force is relatively low.

A very special advantage arises when the cladding panel is additional Has holding elements, for example in the form of punched holes or of openings that engage with corresponding holding elements on the radiator are feasible. If the holes or openings in question are so large that the between, for example, a pair of holding devices and the holding elements maximum possible thermal expansion through a margin between the additional holding elements and the holding elements of the cover plate and the Have the appropriate holding elements on the radiator catch, possibly Expansion noise when heating or cooling the radiator in question only on the first heat cycle that is run through. This not only leads to a reduction in noise pollution, but also that no damage the paint of the radiator in the area of the welding hub of the radiator plates may occur. In later heating cycles, the distance between the holding devices is and the holding elements automatically set so that between the Holding elements on the panel and those on the radiator leave a gap is that offers sufficient freedom of movement.

The openings in the cladding panel of an arrangement according to the invention can be closed at least partially later, for example with a filler, plastic inserts or the like to the optical Improve impression additionally. For manufacturing reasons, this will be however only be made in exceptional cases.

If more panels, on the side or lateral panels In addition, the cladding panels can be provided Have areas, preferably in the outer areas or edge areas, through which holding elements from other cladding plates engage can be brought with the relevant panel and / or the radiator.

However, it should be emphasized that the present invention is particularly advantageous if they are for the panel radiators on the side or lateral areas is trained.

According to the present invention, the arrangement with a radiator with at least one Heating plate provided, which has a circumferential weld seam or transverse seam, and has a device for covering with a covering plate, which comprises at least one holding device. Since the weld or cross seam on the radiator plate or the radiator plates on at least one of them Long sides, which lies in the plane of the radiator plate, a profiling, for example a notch or grooving, so that the holding device or holding devices the panel can be brought into engagement with this profile.

Such profiling on the weld or transverse seam can, for example relatively easily formed by a profile roller, a milling or the like be, resulting in an inexpensive mass production of corresponding Radiators can continue to be maintained and thus also with relative weak holding devices can make a positive engagement, the requires only a small clamping or holding force of the holding devices.

Under certain circumstances, especially when the radiator to be clad has only one heating plate, it may be advantageous if the radiator is at least provided with a tab that has a profile, such as a notch or grooving, and which instead of a profiled welding or Cross-seam radiator plate is arranged such that the at the Cladding device provided holding devices with this profile can be engaged on the tab. If the trained according to the invention Cladding device also has additional holding elements, should also said tab have the corresponding holding elements.

In the figures explained below in connection with the invention same, essentially the same or at least functionally identical parts with named the same or corresponding reference numerals.

In Fig. 1a, a panel 10 formed according to the invention is shown. This has a cladding plate 12, which with holding devices 14a, recesses or openings 16, 18 for the supply or return of a corresponding trained radiator and leg extensions 20 formed on the edge areas is. Additional holding elements 42 can be provided at the upper end, which can be brought into engagement with corresponding holding elements on a radiator are. The lining 10 is formed symmetrically to a central axis 26. However, a cladding designed according to the invention can also be asymmetrical be trained if this is for certain purposes, such as for special radiators, is required.

The holding devices 14a are in the respective outer lateral edge regions of the cladding panel 12, in such a way that corresponding transverse or welding seams (see 58 according to FIGS. 3 to 5) can be gripped from the outside (see Fig. 3a to d). The holding devices 14a are made of the cladding panel 12 cut or punched or the like and bent inward so that they protrude from the plane of the cladding panel 12 at a predetermined angle. An advantageous angle should be around 90 °, depending on the application more acute or further angles can also be advantageous, such as angles between 45 ° and 135 °.

1b shows that the one adjoining the side of the cladding panel 12 Thigh extension 20 for the formation of the holding device 14a has been included.

This is most evident from Fig. 1c, where one to the cladding panel 12 belonging section can be recognized by a lateral leg extension 20 connects. The holding device is essentially from the lateral leg extension punched out, webs 15d (see Fig. 1a) have been formed and a portion 15c of the leg extension 20 remains. The legs 15d in Connection with the hook-shaped extension 15b give the holding device 14a in plan view (view according to FIG. 1b) an essentially U-shaped appearance.

The leg length of the leg 15 of the holding device 14a can be dimensioned in this way be that the statistically expected manufacturing tolerances are compensated can be. About the ratio of the recess 15a or the remaining one Section 15c, the width of the webs 15d, the spring-related holding force of the holding device 14a.

1d shows a cross section through the lining designed according to the invention 10, the level of the holding device 14a according to FIGS. La and b is created. The slightly protruding clip-like holding devices 14a are as protruding from the leg extensions 20 inwards towards the central axis 26 recognizable.

The holding devices can be put together in one piece in just a few steps manufacture with the panel 10 itself, without any additional Work steps would be required. The recesses that are often necessary anyway 16, 18 and their inward folds can, in principle, simultaneously with the Holding devices 14a and / or the holding elements 42 are formed.

The cladding 10 ′ designed according to the invention according to FIG. 2 is in principle constructed in exactly the same way as the embodiment according to FIG. 1.

However, the holding devices 14b differ from the surface of the cladding panel 12 worked out, for example by punching. In principle point the holding devices 14b have the same elements as in the previously described Embodiment according to FIG. 1 can be seen.

The difference is that the legs 15 (see Fig. 2c) from the central axis 26 are bent away to the outside, so that the hook-shaped extension 15b 1c from the inside with the transverse or weld seam of a radiator panel cooperates.

The size of the additional holding elements 42 can be dimensioned such that for the movements to be expected due to the heat cycles that the cladding 10 'compared to a respective radiator, can be compensated can. Instead of the additional holding elements 42 can also on the upper section Holding devices 14a and 14b may be provided, but then to could be feared that the cladding 10 'is noisy compared to radiator covering works, whereby the paint of the radiator is affected could be pulled.

3a shows a plate heater 50 with two heating plates 52, a connecting part 54 and a return 56 by the corresponding punching 18 is led out in the cladding panel 12. The respective heating plates 52 have respective welds or transverse seams 58 in which lie on the outside thereof Rolled side profiles 60 in the form of, for example, grooves or grooves, milled or punched or the like.

The holding devices 14a, which are formed here in the leg extensions 20, engage in the profiles 60 and hold the holding devices 14a and so that the panel 10 in a nearly insoluble connection to the Radiator 50. The connection can only be released using tools.

The leg attachment 20 encompasses the lateral transverse or weld seam 58, which results in an advantageous visual impression.

From Fig. 3b the details of the arrangement can be seen, from which the Holding the panel 10 on the radiator 50 results. The groove 60 has one an abutment resulting edge 60c, the hook-shaped extension 15b of the Holding device 14a can reach behind. An oblique leading edge 60a can assist in the engagement of the holding device 14a in the profiling 60 be. The section 60b parallel to the direction of extension of the heating plate 52 Profiling 60 supports the other end of the hook-shaped extension 15b Holding device 14a. Should it be desired, the holding device 14a and so that the panel 10 to be removed from the radiator 50, so with one pointed or flat object (e.g. a screwdriver) between the stopped section 15c and its hook-shaped extension, that is the opening 15a can be reached through to the hook-shaped extension 15b to disengage from the profile 60.

From Fig. 1b to 1d it can also be seen that the designed according to the invention Cover 10 is able to compensate for manufacturing tolerances that in Form of a differently dimensioned gap or different dimensioned distance 62 can be seen. The spring force of the Holding device 14a with the dimensioning of the length of the leg 15 of the Holding device 14a and possibly the formation of the hook-shaped extension 15b together so that manufacturing tolerances in both the manufacture of Cover 10 or 10 'as well as in the manufacture of the radiator 50 balanced can be.

4a, 4b in principle the same features can be seen as in FIGS. 3a to d, however, the profiling on the transverse or weld seam or hub 58 of a radiator 50 is provided inside. The cladding is accordingly formed according to the embodiment of FIG. 2 and engages with their Holding devices 14b from the inside into the radiator 50. The remaining Components are designed according to the embodiment according to FIGS. 3a to d, manufacturing tolerances 62 can also be compensated for here.

Fig. 5 shows a special case in which the radiator 50 'only from a heating plate 52 consists of an elbow 54 'to a pipe system of a heater or central heating can be connected. To the panel according to the invention or to be able to use the arrangement according to the invention Instead of a further heating plate 52, a tab 70 is provided, which one of the Transverse or welding tab 58 corresponding section with a profile 60th has corresponding profile 72, in which, if appropriate, from the inside or from to engage a correspondingly designed holding device 14a or 14b on the outside can
