The two connections (14) are bonded together by a fixed unit. At least one mounting (18) locks the cap unit (13) to the fixed bond unit, which can be accessed from the side (19) of the connection (1) away from the wall.

Description

The invention relates to a radiator connection with a pipe and a pipe connection for the flow and with a pipe and a pipe connection for the return of the heating medium, both of which are arranged side by side and in a region in which the pipes to be connected parallel, are connected in the assembled position the terminal ends of the tubes each have a widening and / or a clamping ring and are overlapped in the use position of a cap part, which is connected to a connecting part.

Such radiator connections are known. As a cap part serves for each of the two tubes a union nut which detects the pipe extension and / or a clamping ring and connects by their screwing against a connection part, for example, a connection manifold.

This means in many cases difficulties in mounting, because the pipes and their connection ends often emerge from the wall and then the union nut on the wall side of the radiator leading leads are, so that the Fitter behind these leads or behind a terminal block must grab in order to tighten the union nuts can. This difficulty can sometimes lead to inadequate or poor assembly.

From US-A-3'776272 a radiator connection is named, in which the attachment is not made with a cap part, but with a band which is screwed with its two ends. Thus, no flare or ferrule-containing terminal ends of pipes for the heating medium can be collectively detected and fixed.

From US-A-5 467 611 a connection block to be connected pipes of a Klimatisiergeräts is known, in which at its periphery beads having tubular ends are respectively overlapped by anchor plates, which are connected to two fasteners.

It is therefore an object to provide a radiator connection of the type mentioned, in which the assembly or attachment of the connecting parts is simplified to the tubes, even if the or the union parts are on the wall side of this radiator connection.

To solve this problem, the aforementioned Heinzkörperanschluß is characterized in that a common cap part (13) with two parallel receiving openings (15) for the widenings (11) of the terminal ends (10) of the tubes (4,5) and / or for the terminal ends (10) detecting clamping rings (12) is provided, that the two connection parts (14) connectable thereto are connected to each other by a fixed connection part (17), that the two connection parts (14) are designed as parallel connection elbows or angle elements and the connection part (17) runs approximately in the angular range that a fastening element (18) for Connecting the cap part (13) with the connecting part (17) is provided, which from the accessible or wall facing away from side (19) of the radiator connection (1) is actuated, wherein the screw or threaded bolt formed fastening element (18) from the outside of the angle in the connecting part (17) engages and extends parallel to each one angle leg of the connecting part (14).

In this way, the installation can be carried out conveniently from the front of the radiator connection, so for example by the wall and / or the radiator side facing away, so that therefore does not need to be used behind the radiator connection and from this to the radiator leading lines during assembly , The fitter can simply grasp the fastening element on the side facing away from the radiator or the wall from which the pipes emerge and lead to the radiator connection, ie a side facing the interior of rooms, for example, with a tool or possibly also by hand and in the sense the connection to be carried out, ie, for example, tighten a screw or nut or the like.

It is particularly advantageous if the fastener of the side facing away from the cap part of the connecting parts - in particular at the connecting part - is accessible and operable. Thus, the fastener can be tightened, for example, to move the cap part to the connecting parts and set in the sense of a fixation.

It is particularly favorable if the fastening element has a thread and can be screwed from the front or top side of the connecting part of the connecting parts or from the side facing away from the connecting parts of the cap part, wherein the latter applies in the event that the cap part on an accessible side of the radiator connection is located.

Depending on the arrangement leading to the radiator connection and to be provided with this connection ends of the tubes and the subsequent further lines or the like, it may be useful if the fastener is screwed at a point of the connecting part or optionally of the cap part by means of a tool that of the spaced pipes and / or the outgoing terminals or pipes and is free.

For example, the fastening element can be actuated from the side facing away from the radiator and / or spaced apart.

A particularly expedient and advantageous embodiment of the radiator connection according to the invention is possible for the case in which two parallel, designed as a connection bend or angle element connecting parts and extending approximately in the angular range connecting part are provided. The corresponding configuration of the radiator connection with connecting parts designed in this way can be characterized in that the connecting element formed as a screw or threaded bolt engages from the outside of the angle into the connecting part and parallel to each one angle leg of the connecting part, in particular parallel to the connectable with the cap part angle leg runs. Thus, the connecting element, namely a screw or cooperating with a threaded nut nut is very accessible, since in their area, the angle legs recede and thus can not hinder a tool or the like during assembly.

A frequently useful embodiment of a radiator connection with connecting elbows as connecting parts can provide that the cap part engages in the use position on horizontally directed legs of the connecting parts and arranged in the connecting part of the connecting elements connecting element horizontally and can be screwed from the front in the use position side of this connection part. This arrangement is particularly useful when the two terminal ends of the tubes emerge horizontally from a wall and designed as a connecting terminal connecting parts are directed with their outgoing angle leg up, where continuing lines then lead to a heater located above this radiator connection. It results in this application, a particularly good accessibility of the fastener for connecting the connecting parts with the cap part from the room side, in which the radiator and its radiator connection are installed.

As a fastener, as already mentioned, a screw may be provided which passes through a hole in the connecting part or possibly the cap part and in an internal thread of the cap part or optionally of the connecting parts can be screwed, wherein the screw head is arranged at the freely accessible point of the radiator connection. A screw is particularly easy to install and at the same time effective and can take advantage of the cap part with two receiving openings simultaneously to the connector and thereby fix the terminal ends of the tubes.

A modified embodiment may consist in that the Connecting part or optionally the cap part has a through hole or perforation for a arranged in the counterpart and fixed threaded bolt and that for fitting a suitable for this threaded bolt nut is provided, which can be rotated and tightened from the freely accessible side of the radiator connection on the threaded bolt.

According to FIGS. 1 and 2, the two tubes 4 and 5 pass approximately horizontally from a wall 8, while the continuing lines 6 and 7 lead vertically upwards to a radiator 9 at a right angle or come from this. But it is also conceivable that the tubes 4 and 5 also extend vertically, for example, from a floor or horizontally parallel to a wall, in which case the principle of the corresponding radiator connection 1 is used in the same way.

In all embodiments, the terminal ends 10 of the tubes 4 and 5 each have a widening 11 (Figures 3 and 4) or an externally acting clamping ring 12 (Figures 5 and 6) or optionally a widening 11 and a clamping ring 12 (Fig ), wherein the widening 11 or the clamping ring 12 are each overlapped by a cap part 13, which with a connection part 14 is connected in the assembly or use position in a manner to be described.

It can be seen in all embodiments, that a common cap part 13 is provided with two parallel receiving openings 15 for the widening 11 of the terminal ends 10 of the tubes 4 and 5 and / or for the terminal ends 10 detecting clamping rings 12.

For the spread of widenings 11 15 constrictions 16 are provided according to Figures 3 and 4 at the receiving openings, which are also available in the solution with clamping rings according to Figure 5 and 6 in an adapted form.

The two with this common for the two tubes 4 and 5 cap part 13 connecting parts 14 which are coupled to the continuing lines 6 and 7 are connected by a fixed connection part 17 with each other and thus made into a single mounting part. Further, a fastener 18 is provided for connecting the cap part 13 with the connecting part 17, which considerably simplifies the assembly. In this case, this fastener 18 from the accessible, so the wall 8 opposite side 19 (vgl.Fig.2) of the radiator connection 1 from accessible and can be operated from there, so in particular brought into its mounting position and tightened for sealing the radiator connection 1 in that the capping part 13 is moved and pressed against the connecting parts 14 by its actuation, thereby clamping the connecting ends 10 of the tubes 4 and 5.

Especially in Fig.1, 2 and also in Figure 7 it can be seen that the fastener 18 is accessible and operable from the side facing away from the cap part 13 of the connecting parts 14, so that a virtually unhindered mounting of this fastener 18 is made possible.

Accordingly, the radiator connection 1 in the illustrated embodiments has two parallel, designed as a connection bend or angle element connecting parts 14, the connecting part 17th extending approximately in the angular range, so that the fastening element 18 is located at the height where the horizontally extending tubes 4 and 5 and the corresponding angle leg of the connecting part 14 are deflected in the vertical direction upwards.

The trained as shown in Figures 1 to 6 as a screw fastener 18 engages from the outside of this "angle" in the connecting part 17 - while horizontally extending in use position - and extends parallel to the connectable with the cap part 13 angle leg of the connecting part 14 and the Terminal ends 10 of the tubes 4 and 5.

In the embodiment of Figure 7, the fastener is connected to the cap part 13 threaded bolt, which cooperates with a belonging to this fastener 18 nut 18a in use position, which is also actuated by the front or outside of the connecting part 17 and when donning the cap part 13th with its threaded bolt accordingly pulls against the connecting parts 14, thereby causing a jamming of the tubes 4 and 5.

In the embodiment according to Figures 1 to 6, therefore, a radiator connection 1 is provided, in which a screw is provided as a fastening element 18 which passes through a hole of the connecting part 17 and into an internal thread of the cap part 13 is screwed, so that the screw head at the freely accessible Position 19 of the radiator connection 1 is arranged.

In Figure 7, the connecting part 17 has a through hole or perforation for a on the counterpart, so arranged and secured to the cap part 13 as a fastener 18 threaded bolt for fitting to this threaded bolt nut 18a, which is accessible from the free side 19 of the Radiator connection 1 off on the threaded bolt is twisted and tightened.

The cap part 13 thus engages in the use position of horizontally directed legs of the angular connection parts 14 and engaging in the connecting part 17 of the connecting parts 14 connecting element 18 is, as already mentioned, arranged horizontally and 17 screwed from the front in the use position side 19 of this connection part. Thus, it is easily accessible and the entire assembly of the radiator connection 1 can be conveniently carried out, for example, from the wall 8 remote from the room side, without being obstructed by fittings or pipes 6 and 7 or the like connecting the pipes 4 and 5 with the radiator 9.

The radiator connection 1 serves to connect two parallel tubes 4 and 5 for the flow and for the return of the heating medium simultaneously to a radiator 9, wherein for the two tubes 4 and 5, a common cap part 13 with two parallel receiving openings 15 for the terminal ends 10 of Pipes 4 and 5 is provided. This connectable connecting parts, which are coupled in particular via further lines 6 and 7 with the radiator 9, have a fixed connection part 17 between them and each other and the cap part 13 is connected to this connecting part 17 with at least one in particular approximately in the middle between the tubes 4 and 5 and the lines 6 and 7 engaging fastener 18 connectable and attracted to each other, the fastener 18 or a belonging to him mother 18a or possibly also a lever of a bracket of the wall 8, in front of which the radiator 9 is located, away from or from the room side is accessible from 19 accessible and fixable.
