Abstract

The invention concerns an adapter for use in refitting radiators (14), a radiator (14) fitted with such an adapter and a method of manufacturing the adapter. The adapter has a mounting (1) which can be attached to the radiator (14) at any desired point, pipe connection pieces (3, 4) on the mounting (1), connection fittings (8, 9) for connecting the adapter to the radiator terminals (15, 16) and lines (6, 7) each of which connects a connection fitting (8, 9) to its associated pipe connection piece (3, 4). The terminals are preferably located underneath the radiator at one end, and the mounting is attached to the centre (18) of the radiator, thus ensuring that a radiator fitted with an adapter can always be connected up, irrespective of its width, to centrally laid heating pipes so that it is centred. In the method proposed, two pipes (6, 7) are cut to the same length, attached to the pipe connection pieces (3, 4) and the connection fittings (8, 9) and bent to shape so that they lie next to each other at the same height.

Central connection of radiators

The invention relates to a connection fitting for equipping or converting a radiator with connections arranged near a side edge (preamble of claim 1), furthermore to a radiator equipped with such a connection fitting (claim 13) and a method for producing such an adapter

All of the spatial positional designations used here are based on the conventionally mounted radiator with the adapter attached to it, the radiator overall having approximately rectangular or, in particular, cuboidal contours and its edges running horizontally or vertically.The adapter can be attached to the underside of the radiator and located in extend substantially horizontally

So far, all radiators had connections on their underside near one side edge. However, this has certain problems. For example, the horizontal dimensions of each radiator must be known when the shell is installed, when the heating cables are installed

If you later decide to mount a narrower or wider radiator, then you have to accept that this radiator is no longer mounted in the center of an overlying window. In addition, a distinction must be made between radiators with right and left connection accidentally heater

ordered or supplied with the connections on the wrong side, then these cannot be installed

On the other hand, it requires the large number of existing types of radiators. that a entspre ^¬ accordingly aroße number is available at different connection fittings. even if white side fittings would be attached.

The object of the invention is to at least partially overcome these disadvantages.

This object is achieved by one of the type mentioned above, with a bracket that can be attached to a desired location of the radiator, pipe end pieces that are attached to the bracket, connecting sections for connection to the connections of the radiator, and lines that each connect a connection section with the associated end piece (claim 1).

By means of this fitting, a wider radiator can now be installed instead of a narrower radiator so that its connections protrude laterally over the ends of the heating pipes; instead, the bracket with its connection end pieces is located exactly above heating lines. A wider radiator than originally planned can also be installed in such a way that it is installed in the middle of a window above it, for example.

By means of the fitting according to the invention, however, it is also possible to equip or convert a radiator with right-hand connections in such a way that it can be used instead of a radiator with left-hand connections and vice versa.

The radiators can be equipped or retrofitted by the manufacturer, dealer or on site; it is thus possible, for example, to retrofit unsuitable stocks or deliveries.

A particularly advantageous embodiment of the connector assembly of the invention is obtained when the lines, the compounds according to the line end fittings and the connecting sections are assigned to the ^_¬, a Baulängengarnitur that is measured depends on the overall length of a radiator directly ^¬ pers. In this way, it is possible to meet the requirements of various radiators with different dimensions in that only the overall length trim is produced in different dimensions, in order in this way with suitable Leitunas end connections or connecting sections for connecting or converting one A variety of radiator types can be used.

A further particularly advantageous embodiment is obtained if the line end connectors and / or the holder or the connection sections are assigned to a set of height which is dimensioned depending on the height of the radiator or the installation situation. Here, as in the case of the advantageous embodiment with the overall length set, a component with different dimensions can be provided, which can be combined with existing lines or existing full length sets in order to provide a large variation in connection fittings ultimately assembled for different types of radiators or installation situations surrender.

In this way, the two very advantageous embodiments described can be used to significantly reduce the storage and the variety of parts. For example, with five different heights and an additional 10 to 15 lengths, 50 to 75 different fittings can be manufactured.

Of course, connection fittings with features according to the invention can be used both for retrofitting and for the basic equipping of radiators of various dimensions.

According to claim 4, however, it is particularly advantageous if the holder is located in the middle of the underside of the radiator. It can thus be equipped with a fitting according to the invention, any radiator, the connections of which are attached to the lower edge, so that the pipe end connections, which are to be connected to the ends of the building-fixed heating pipe, are in the center.

This configuration presupposes that the heating lines to each attachment point must be arranged in the shell. However, if this is done, you are later completely free to choose the dimensions of the radiator, because regardless of its width, each radiator has a central connection thanks to the adapter according to the invention and can always be mounted centrally at the respective attachment point, since the heating lines are also central are arranged. Heating lines pre-routed in the middle, for example under windows, now fit all heating bodies with a fitting according to the invention with a central holder.

The holder can be designed in any manner, for example as a clamp, but is preferably designed as a horizontal, generally flat holding plate which can be attached to the underside of the radiator. In this case, the holding plate can assume such a position that the line end connections arranged on it assume the same orientation and height as the original connections of the radiator.

The holding plate could be spotted on the radiator: according to claim 6, however, it is locked by means of a resilient clamping device on the radiator, so that it can be attached in a very short time and without additional tools.

The resilient clamping device could be designed in the usual way with spring-loaded, separate locking bodies; According to claim 7, a particularly simple and therefore advantageous solution lies in the arrangement of at least one and preferably two U-shaped wire spring clips on the holding plate in such a way that the legs of the wire spring clips protrude upwards and are designed to evolve in configurations of the Jamming the radiator.

For this purpose, the wire brackets are preferably bent outwards near their ends, in order in this way to be able to reach behind the heating element in a resilient manner.

The retaining plate can be firmly and reliably attached to a radiator with this resilient clamping device, but can optionally be easily removed from it. So it is possible to replace a radiator, without having to switch the valve from ^¬.

In principle, the clamping effect provided by the wire spring clips is sufficient ^to adequately fasten the holding plate.

According to claim 8, however, the holding plate additionally has, in the region of its corners, laterally angled tabs which relate to counter-configurations of the radiator from below support here; just before the legs of the wire spring clip reach their end position when reaching behind the radiator, the tabs sit on and are now pulled resiliently into their seats.

It is fundamentally possible to design the line end connectors and / or the connection sections as conventional sleeves which have an external or internal thread at one end, while the other end opens axially into the respective line end. To do this, however, it would be necessary for line ends to extend from the connections downwards or into the interior of the radiator and from above into the line end connections.

According to a further variant of the present invention, a connection fitting with features according to the invention can also be provided on the holding device or the holding plate with attachment sections in order to produce a welding and / or soldering connection, or an adhesive connection between the connection fitting and the radiator . This type of connection is particularly preferred when radiators are already equipped in the factory with the connection fitting according to the invention.

The holding device or the holding plate can be fixed on the lower section of the radiator, in particular on the longitudinal seam of the radiator or its heating plates or a radiator convector of the radiator.

According to claim 11 or 12, however, it is advantageous to run the lines laterally into the line end connector and / or the connection sections; this avoids leading the lines downwards and / or upwards beyond their level.

Ideally, the terminal portions and the end stub line lie approximately in the same horizontal plane so that the two lines extend adjacent one another substantially hori zontal ^¬.

The lines are preferably even crimps to the line end stub out slightly above ge ^¬, so that the fitting to existing heating pipes derseleben approximately Monta ^¬ gehöhe can be connected, as would be the case with the original connections of the radiator. As already mentioned, the connection fitting or fitting according to the invention can be supplied and installed as a special element; However, it is also possible to supply the radiator with a built-in fitting, for example in the case of centrally laid heating lines, so that the invention according to claim 13 is also expressly directed to such an adapted radiator.

When assembling the valve according to the invention, it is fundamentally possible to manufacture all of the individual parts in their final form and then assemble them, or to prefabricate sets of individual parts sets (claims 2, 3) and install or assemble them for specific uses.

According to Claim 14, however, it is preferred to first manufacture the lines as straight line sections and to attach them to all line end connections and connection fittings.

The pipes are only bent into their final shape after complete assembly; it can be ensured in a simple manner that all the connecting elements connected by the lines assume their final position precisely without having to work with corresponding accuracy as a whole, since minor length errors can easily be compensated for by a larger or smaller radius of curvature of the lines.

The object of the invention is explained in more detail with reference to the attached schematic drawing, for example; in this shows;

La is a view of an embodiment of an adapter according to the invention, seen from below, partially in section,

1b shows a front view of the adapter of FIG. 1, partly in section,

1c shows a section A-A from FIG.

Fig. 2 is a partial front view of a heating element, partially cut away, with eingebau ^¬ adapter system of FIGS. La-lc, 3 is a view of the radiator section with adapter of FIG. 2, seen from below,

Fig. 4 is a view of the radiator section with the adapter of Fig. 2, seen from the side, partially cut.

In the drawing, the same reference symbols mean the same elements throughout the figures; Insofar as an element shown in one figure does not have a reference number for the sake of clarity, reference is made to the reference number of this element in another figure.

In Fig. La-lc an embodiment of the adapter is shown. This consists of a holder, generally designated 1, with a flat, horizontal, rectangular holding plate 2, the other underside of which a first and a second line end connector 3, 4 are attached by riveting, resistance welding or the like.

Each pipe end connector 3, 4 is formed by a compact cylindrical component, which has a projecting external thread 5 at its lower end. A blind bore extends inwards from this lower end. The wall of each line end connector is penetrated by a horizontal bore above the external thread 5, the diameter of which is slightly larger than the diameter of the blind bore into which it opens.

The pipe end connectors 3, 4 are aligned vertically with their cylinder center axis and intersect with this the larger center axis of the rectangular holding plate 2, which runs parallel to the longer sides thereof. The resulting intersection points are located on both sides of the other, smaller central axis of the holding plate 2, which is taut on the shorter sides thereof, at the same distance from the latter.

The axis of the horizontal bore of the first conduit end connector 3 roughly faces the second conduit end connector 4, but is inclined forwards or backwards by approximately 25 ° with respect to the larger central axis; the horizontal axis of the bore of the second conduction Endstu _t zen 4 facing away from the first line end stub 3, and compared to the large- Ren center axis inclined by about 25 ° forwards or backwards, but to the other side than the horizontal bore of the first pipe end connector.

On the two ends of the long sides of the holding plate 2 outwardly projecting tabs 13 are formed, which protrude upward by approximately 45 °. Two tabs are punched out of the narrow sides of the holding plate 2 and bent so that they each hold a transverse web of a U-shaped wire spring clip 11. These crosspieces extend in a straight line at a short distance from the narrow sides of the holding plate 2 and sit on the top thereof (see in particular FIGS. 1b and 1c).

The two legs of each wire spring clip 11 protrude perpendicularly upward from the holding plate 2 and are at a distance from one another which corresponds approximately to the length of the narrow side.

Near their upper ends, the brackets are bent outwards and back again to form bulges 12.

At a considerable distance from the holding plate 2, a first connection fitting 8 and a second connection fitting 9 are arranged, each of which is formed by a cylindrical component which, in terms of design and dimension, corresponds to the line end connections, but instead of the external thread has a light flange and with it Mouth is directed upwards. A union nut 10 engages under the flange.

The cylinder central axes of the two connection fittings 8, 9 lie on the extension of the larger central axis of the holding plate and are at a mutual distance which corresponds to that of the line end connectors 3, 4.

The upper ends of the terminal fittings 8, 9 are of the same height as the retaining ^¬ plate 2. The bore of the two connection fittings 8. 9 in the direction of the management end fittings _3, 4 garment _t and with respect to the extension of the longer central axis of both ^¬ hand this inclined as the bores of the line Endstu ^t by a similar angle zen _3, 4, in the first terminal fitting 8 to the same side as 3 in the first conduction in the second end socket connection fitting 9 to the opposite side. 54

The holes of the first line end connector 3 is connected to that of the first connection fitting 8 by a first line 6, the other two holes connect a second line 7. Each of the lines 6, 7 extends on one side of the elongated long central axis with its ends slightly angled and is slightly cranked in its central section, since the bores in the connection fittings 8, 9 are a little lower than the bores of the line end connectors 3, 4.

In addition, the outer surface of the first connection fitting 8 and the second connection piece 4 is recessed in order to allow the second line 7 or first line 6 to run as close as possible to the longer central axis or its extension, and also for each line 6, 7 to create an additional anchor.

The attachment of the adapter of FIGS. 1 a to 1 c to a radiator 14 is shown in FIGS. 2 to 4.

The radiator 18 has a vertical center line 18 (FIG. 2) which intersects the minor axis of the holding plate 2.

On the lower left side, as seen from the front, the heating element 14 has a first connection 15 and a second connection 16, each of which is formed by a pipe socket which is open at the bottom and has an external thread at the lower end on which the union nuts are 10 are screwed on, which connect the connection fittings 8, 9 sealingly to the connections 15, 16.

Wall brackets 17 are provided on the rear.

As seen from Fig. 4, the holder 1 of ago pushed down into a recess of the heating ^¬ body 14, wherein the projections engage over projections 12 of the radiator 14 while 13 are seated from below the tabs on the radiator.

The two line end connectors 3, 4 thus provide center connections for the radiator 14 provided with the adapter. It should be noted that the connection fitting with a feature according to the invention can not only be used for retrofitting at the dealer or on the construction site, but can also be used directly in the manufacture of a radiator

Of course, all individual parts of the connection fitting with the features according to the invention can of course each be attached to the radiator separately or preassembled.

However, it is particularly preferable if, for example, the lines 6, 7 are assigned to a structural length set which are put together in a plurality of pre-assembled sets which match certain heater lengths and are stored for specific purposes

Correspondingly, the cable end connections 3, 4 can also be combined to form a set of heights, in particular in connection with the holding plate 2. Several sets of heights with different dimensions are provided in a vertical orientation to the radiator in order to also be able to meet various types of radiators and / or installation situations.

In other words, length sets and / or height sets are prefabricated which have different lengths in the horizontal direction to the radiator or heights in the vertical direction to the radiator. These different prefabricated sets can then be put together for specific types of radiators / installation situations to form connection fittings with a feature according to the invention

Such terminal fittings with a feature of the invention, which can already be fitted by the manufacturer, may also be provided with neck portions for the purpose of the final assembly in a Ferti ^¬ Gungstraße to weld, solder or adhesive - to be technically fixed to the Heizkoφer
