Description

Mounting device for lower flow and return connections in a radiator system

The invention relates to a mounting device for lower flow and return connections between a radiator that can be suspended from a bracket, in particular a panel radiator, and connection fittings for pipes.

The manufacturer takes great care in the manufacture of radiators and their smooth and/or profiled surfaces are used in heating systems to transfer the heat supplied by the heating water to the rooms to be heated by convection and radiation. Flat radiators are divided into single-row and multi-row/multi-layered versions, in which wave-shaped convector plates are arranged between water-flowing heat plates. The width and number of convector plates determine the depth of the radiator in question. The radiator can be operated in two-pipe or one-pipe mode and is connected to pipes at integrated lower flow and return connections via lockable, if necessary pre-adjustable, connection fittings after it has been installed at its location.

The installation process is made easier by wall or floor brackets, which can have upper and/or lower spring-loaded clamping devices for the radiator. The disadvantage, however, is that during the shell assembly, the finished, highly sensitive radiators must be installed in order to be able to use their lower flow and return connections as a guide when laying the pipes, which are later covered with insulation and screed. After adjusting the connections of the ascending pipe branches to the positions of the flow and return connections of the radiator, the radiator is dismantled again because it interferes with work in the adjacent wall and floor area. From now on, numerous radiators stand or lie around in the unfinished room and, due to displacement and impacts, become deformed and even leak, which impair their later function and appearance. Paint damage is unavoidable and considerable subsequent reworking is necessary. The radiators standing around also hinder and endanger the tradesmen, who are also subjected to additional physical strain by repeatedly moving the radiators.

The invention is based on the object of creating a mounting device for lower flow and return connections between a radiator that can be suspended from a wall or standing bracket, in particular a panel radiator, and connection fittings for pipes, which makes radiators unnecessary when setting up the pipes.

This object is achieved according to the invention by a bracket that can be attached to the bracket and that has a support for a lower radiator edge and two continuous

Has holes for receiving external threads of the connection fittings, whereby the distances between the hole centres from each other and from the support are adapted to the corresponding dimensions of the flow and return connections of the radiator.

The bracket according to the invention enables the pipes for the flow and return of a radiator to be set up without the radiator being present, i.e. the bracket is a dimension that remains in place and, after being attached to a wall or stand, simulates the radiator connections that are important for the flow and return installation. In a shell, the wall or stand brackets for the radiators provided are properly installed and instead of the radiators, brackets are attached that allow the heating engineer to align and bend the pipes for the flow and return according to the conditions of the desired radiator. External threaded pieces of the connection fittings are inserted into the through holes and connected to the connection screw connections of the pipes via connection fittings. This arrangement is kept ready unchanged. The radiators are only delivered when the room is completely finished. They can be immediately hung on the wall or standing bracket and the external threads in the bracket, which are precisely fitted to the flow and return connections of the radiator, only need to be screwed tight. The assembly device according to the invention makes the heating installation easier, from laying the pipes to fitting the radiators, and contributes to a significant reduction in costs by reducing the working time. It also protects the new radiators from damage caused by rough handling in the shell and saves the

costly reworking of damaged and/or bent radiators by hand.

In an advantageous embodiment of the invention, each hole is a threadless plug hole in which a protective cap part with an internal thread and clamping ring secures the external thread piece. The threadless plug hole is advantageous because simply pushing the external thread piece through and attaching the connection screw of the pipe already achieves a certain fixing of the pipe in the desired position. There are no tight tolerances to be observed and the bracket itself can be designed as an inexpensive part. The protective cap part with an internal thread is screwed onto the external thread piece and fixed in the plug hole with the help of the clamping ring. In this way, the bracket with the external thread pieces is a unit prepared for connection. The external thread piece also does not fall out of the plug hole if the connection fitting is removed for any reason.

The bracket is preferably designed as a horizontally oriented plate body that has connecting means for connection to the bracket. The connecting means can have an angled leg with at least one screw hole through which a screw is inserted and screwed into a room wall serving as a bracket, for example. Additional spacer rings/pieces can be used for mounting on the rough wall, which specify the thickness of the plaster. A holder for a rod with a safety device for an upper radiator edge is preferably arranged on the angled leg of the plate body. Such a safety device can be a spring-loaded claw, among other things.

which overlaps the upper edge of the radiator and is in the vertical alignment of the support on the console.

In a further expedient embodiment of the invention, the connecting means can be a slip-on sleeve for a post of a stand holder, which is provided with a safety device for an upper radiator edge.

Such a stand is advantageous if, for example, a wall mount cannot be used due to lightweight walls, sloping roofs or other reasons. Stand mounts generally consist of a base with a vertical post onto which the radiator is placed from above and to which it is secured using clamping parts that serve as a safety feature. The sleeve on the panel body is placed on the post and secured to it. The support for the lower edge of the radiator can be attached to the sleeve and/or to the panel body. It is important that it lies on a line that is parallel to the line connecting the two holes and that the distance between the two lines is adapted to the corresponding dimensions of the flow and return connections of the radiator.

The distances between the hole centers and the support depend on the type of radiator in question and the distance between its flow and return connections and the rear lower edge of the radiator. Accordingly, the plate bodies of the mounting devices are equipped with different hole arrangements. For example, in narrow single-layer radiators with only one convector sheet, the hole centers have a distance of approx. 3 0 mm from the support. For two-layer radiators with one or two convector sheets, the distance is

the distance between the hole centers and the support is approximately 40 mm. The mutual distance between the hole centers is generally approximately 50 mm.

The two holes can be formed in the surface of the plate body itself.

According to a further embodiment of the invention, the two holes are formed in a rectangular insert plate that can be inserted into a recess in the plate body that is open on one side. In this way, a single console can be fitted with insert plates with different holes to suit different radiator depths. It is even more advantageous if the two holes are offset laterally in relation to the longitudinal center line of the insert plate. In this way, by turning the insert plate over, the distance between the holes and the support for the lower edge of the radiator can be increased or reduced and an adjustment to the position of the flow and return connections of the radiator can be achieved.

A mounting device for lower flow and return connections between a radiator that can be suspended from a bracket and connection fittings for pipes consists in the example according to Figs. 1 to 4 of

a bracket 10 which is attached to a room wall 11. The bracket 10 is designed as a horizontally oriented trapezoidal plate body 12 made of sheet metal, the tapered end of which is provided with a leg 13 bent upwards at a right angle. In the lower area of the leg 13 there is an elongated horizontal screw hole 14 through which a threaded bolt 15 is inserted, which is screwed into the wall 11 and supports the bracket 10. At a distance from the leg 13 on the center line of the plate body 12 there is a support 16 made of plastic which has an upwardly open, V-shaped recess in which the lower edge 20a of the rear heating plate 20c of a flat radiator 20 is received (Fig. 4). In front of the support 16 there are two threadless circular holes 17 and 18, the connecting line passing through their centers runs parallel to the longitudinal extension of the support 16 and to the leg 13. The holes 17 and 18 pass through the plate body 12 and have the same diameter. The diameter of the two holes 17 and 18 is approximately 30 mm and their centers are 50 mm apart. This distance corresponds to the distance between the flow and return connections 21, 22 at the lower end of the panel radiator 20 (Fig. 5).

The diameter of the holes 17, 18 is larger than the largest outside diameter of external threaded pieces 23, 24, which are designed as reducers with a smaller upper and a larger lower thread diameter. The external threaded pieces 23, 24 belong to connection fittings 25, which together with connection screw joints 26 create connections between the flow and return connections 21, 22 of the radiator 20 and pipes 27, 28. The connection fittings 25

· a

can be suitable for one-pipe or two-pipe operation. The one-pipe connection fitting can be shut off using a bypass set.

Flat radiators 20 have different installation depths depending on the number of corrugated convector sheets between the heating plates. Accordingly, the flow and return connections 21, 22 have different distances from the rear lower radiator edge 20a, which rests on the support 16, and the ends of the pipes 27, 28 must be aligned accordingly. In order to take this difference into account, the distances of the centers of the holes 17, 18 from the support 16 are different, and plate bodies 12 are to be provided in which the distance is approximately 30 mm (shown in solid lines in Fig. 1) and those in which it is approximately 40 mm (shown in dashed lines in Fig. 1). The 30 mm version is suitable for a radiator 20 with a small installation depth and the 40 mm version is suitable for a multi-layered, deeper radiator 20.

The angled leg 13 has a holder 30 on the side facing the holes 17, 18 in the form of a box-like pocket that is closed at the bottom and open at the top. The pocket accommodates a rod 31, which is a stable profile part and is attached to the wall 11 with the aid of at least one screw 32. At the upper end of the rod 31 there is a spring-loaded holder 33 that overlaps the upper edge of the radiator 20b (Fig. 4) and holds the mounted radiator 20 in a vertical position. The spring-loaded holder 33 and the support 16 are in a common vertical alignment. Depending on the length of the respective radiator 20, additional spring-loaded holders 33a are provided. As shown in Fig. 5, these are attached to a separate

attached to a ready-made rod 31a, which has its own plastic support 16a at its lower end.

When the supply and return pipes 27, 28 are to be installed in a shell, a bracket 10 is mounted at the location intended for the radiator 20 and external threaded pieces 23, 24 are inserted into the two holes 17, 18. A protective cap part 35 with an internal thread and clamping ring 36 serves to prevent them from falling out. The protective cap part 35 is screwed onto the upper thread of the external threaded piece 23 or 24 and pressed into the unthreaded hole 17 or 18 with the clamping ring 3 6. Two axially spaced circumferential flanges of the clamping ring 3 6 prevent the external thread pieces 23, 24 from falling out of the holes 17, 18. Now the ends of the pipes 27, 28 are bent and aligned according to the axial alignment of the external thread pieces 23, 24 and the state of the attached radiator 20 is simulated by inserting the connection fittings 25. After the alignment work has been successfully completed, the pipes 27, 28 remain in the state shown in Fig. 3, with the dashed lines symbolizing the connection fittings 25. The construction work continues unhindered by radiators lying around. The pipes 27, 2 8 are covered with an insulating layer and screed 3 7 and the walls are treated in a suitable manner. If plastering of the walls is planned, the bracket 10 is placed on spacers (not shown) that bridge the thickness of the plaster layer that is not yet present during the shell construction. Only after completion of the room are the new radiators 2 0 delivered and immediately installed, resulting in the state shown in Figs. 4 and 5, in which the spacers serve as dimensional intermediaries between the flow

and return connections 21, 22 of the radiator 20 and the ends of the pipes 27, 28 remains in place.

The above statements made regarding the assembly and the function of the bracket 10 also apply to the second embodiment of an assembly device according to Figs. 6 to 11. In this case, a bracket 110 consists of a fork-shaped plate body 112, in which a leg 41 angled upwards at a right angle is attached or formed onto a closed straight sheet 40 and from which two parallel arms 42, 43 protrude at the front at a mutual distance. The two arms 42, 43, together with the front edge of the sheet 40, delimit a recess 44 that is open on one side. The arms 42, 43 are stiffened on the outer longitudinal edge by bent sections 45 that protrude into the sheet 40. A box-shaped holder 45, open at the top, is attached to the front surface of the leg 41 and is penetrated by an elongated, vertically oriented screw hole 47 on the front and rear walls. Two further vertically oriented elongated screw holes 48 are formed in the leg 41 outside the holder 46. Threaded bolts 49 are inserted through these, which serve to attach the bracket 110 to the wall 11.

The two arms 42, 43 of the plate body 112 form guides and holders for a rectangular insert plate 50 (Fig. 8) which can be made of plastic or sheet metal. Straight grooves 51 are formed on the two shorter edges of the insert plate 50, which fit together in a tongue and groove manner with the straight edges of the arms 42, 43 facing the recess 44. In the assembled state shown in Fig. 10

the insert plate 50 fits snugly in the recess 44 and the plate body 112 is ready for use in the same way as the plate body 12 of the first example. The insert plate 50 is provided with two adjacent unthreaded holes 117, 118. They are circular and have a diameter of about 30 mm to match the diameter of the external thread pieces 23, 24. The two holes 117, 118 are offset laterally in relation to the longitudinal center line of the insert plate 50, i.e. they are closer to the longitudinal edge 50a than to the longitudinal edge 50b. This means that a bracket 110 with the insert plate 50 can equally cover two installation depths and corresponding distances of the flow and return connections 21, 22 from the rear lower radiator edge 20a. For 30 mm distances, the insert plate 50 is inserted into the recess 44 so that the holes 117, 118 assume the position shown in solid lines in Fig. 10. To determine the 40 mm distance, the insert plate 50 is pulled out and turned over so that the edge 50a faces outwards and the holes 117, 118 assume the dashed position.

After the console 110 has been properly equipped, the external thread pieces 23, 24 are inserted into the holes 117, 118 and the pipes 27, 28 are aligned as described for example 1. The external thread pieces 23, 24 are secured in the holes 117, 118 by the protective cap parts 35 with clamping ring 36. After this work has been completed or at a later point in time, the lower end of a rod 131 is inserted into the holder 46 and secured in the holder 46 and to the wall 11 using a threaded bolt 52. The rod 131 has at its upper end the securing device 33 shown in Fig. 4, which secures the upper

outer edge 20b of the radiator 20 and holds it in position.

The third embodiment according to Figs. 12 to 14 relates to the attachment of a bracket 210 to a stand. A stand usually consists of a post 60 with a rectangular cross-section, the lower end of which is fixed in a base 61 screwed to the floor. The radiator 20 is placed on the post 60 in such a way that it penetrates into a gap between the corrugated convector sheets and the lower edge of the radiator 20a rests against a support. A support 64 is located according to Fig. 12 on a slip-on sleeve 65, which is secured to the lower end of the post 60 with the aid of a pressure screw 66, for example. A plate body 212 of a bracket 210 is also connected to the slip-on sleeve 65. This can, as shown in Figs. 12 and 13, by inserting a downwardly angled leg 67 into a vertical slot on one side of the push-on sleeve 65 and by securing the leg 67 in the slot using a pressure screw 68. The plate body 212 made of thick sheet metal has an L-shape in plan view and in the wide part 70 extending transversely from a narrow part 69 there are the two circular holes 217, 218 which correspond to the holes 17, 18 and 117, 118 in the plate bodies of the other examples and serve the same purpose. The distances between the centers of the holes 217, 218 and the support 64 are 30 mm and 40 mm respectively, in accordance with the conditions in the radiator 20. The external threaded pieces 23, 24 for connecting the pipes 27, 28 to the flow and return connections 21, 22 of the radiator 20 are inserted into the holes 217, 218.

-IA-

and secured in the holes 217, 218 by means of the protective cap parts 35.
