EP0733867B1 - Installation for mounting a radiator on a wall - Google Patents

Abstract

The device has two support forks (4) for supporting the radiator (1) underneath and has hooks above for holding back the radiator. Both support forks form one support element (5) which is fixed to the wall (2) and has a circular formed seat (6) having a rotatable fastening element (7). The fastening element is composed of two half elements (7',7") which are mirror images of each other and are in the form of horseshoes having an opening (8) in which a cylindrical formed support area (9) of the radiator is positioned. The two halves are rotatable against each other so as to form a vertically upwards opening for the support area of the radiator which is inserted into the opening vertically from above and hooked onto the upper hooks.

Description

The present invention relates to a device for fastening a radiator on a wall, according to the preamble of claim 1.

Devices of this type for fastening a radiator to a wall meet today's requirements for easy installation of the Heating system as well as hygiene and cleanliness. The conventional fastening systems for radiators with fixed lower brackets, on which the radiator supported, and with an upper, also permanently arranged fastening element, that prevented the radiator from tipping over sideways, required very precise positioning of the tubes for the lead and the return, as there was no way, the position of the radiator to adapt to the pipe connections. Moreover, such Radiators were relocated once and for all and later on Lifetime never decreased - unless there were compelling reasons such as. a replacement of the radiators - so that access to the wall behind the radiator only with luck, which in practice was never a thorough one Cleaning of the area between the radiator and the wall allowed. In this The area has therefore been able to contaminate everyone over the years Kind accumulate, with corresponding impairment of the hygiene of the whole room.

There are numerous proposals to overcome these difficulties the radiator to make it fold away from the wall so that the area behind the radiator becomes accessible for the necessary cleaning operations.

In general, these proposals provide, represented in the sense of examples in patent applications CH-A-666537, DE-A-4327077, DE-A-4236231, DE-A-4129299 that the radiator means on its lower part two support forks is carried, while at least one on the upper part Hook is provided, which holds the radiator from the danger on the side, i.e. to tip forward. It is clear that in such an arrangement Usually two lower support forks are required to keep the horizontal Ensure alignability of the radiator and at least one retaining hook. In many cases the lower support fork and the upper one are as Spring-formed hook retaining element in a single fastening rod summarized (see e.g. patent application DE-A-4236231, or also DE-A-4129299), but this is certainly for the attachment not necessary: if already, this serves to facilitate the attachment (Only the fastening rod is to be attached, whereby one does not look around must take care of the mutual position of the support fork and the upper hook) and to rationalize production (the required fasteners are all the same).

However, these known fastening systems have the major disadvantage that they do not take the raw connections into account, so definitely do not take into account where these tubes are in the room. The consequence of which is that these fixings, unless you choose flexible pipe connections, no folding down of the radiators allowed without the water-carrying Tubes are removed, so that these fastenings in the Practical use not suitable, foldable radiators for cleaning purposes to accomplish. So there are systems with which a fast and safe installation of the radiators is achieved, but not to systems that the problem of ease of cleaning the space between Radiator and wall could solve, because for such cleaning operations is certainly out of the question that the tubes for the forward and the return the water must be dismantled, and that the whole heating system must be emptied.

To avoid these disadvantages, proposals have already been made according to which the radiator folded down about a horizontal axis which coincides with the axis of the connection valve. A solution this type is e.g. shown in patent application EP-A-0492957, in which the Radiator has a flow connection on one and a return connection on the other side of the radiator so that it folds down the radiator around the common horizontal longitudinal axis of the two Connections are made.

The disadvantage of this mounting system for the radiator is that that a flow connection on one and a return connection on two opposite sides of the radiator, i.e. far apart, must be attached. This does not allow an optimal design the pipes of the heating system, since you can see the arrangement of the two connections is bound on one side of the radiator.

According to a form of feeding a radiator known from EP-A-666440, at which uses a connection valve with rotatable chambers, It is proposed that a valve with a rotatable valve should be used Chambers to use that both the water pipe for the flow as well also includes those for the return, and which is designed so that there is a Rotation of the radiator around the axis of this valve is permitted and suitable, disconnect the radiator from the connecting tubes after the valve is in a suitable position has been placed without the heating pipe system must be emptied.

• Befestigung eines abklappbaren Radiators, unabhängig davon, ob die Röhren für den Vorlauf und für den Rücklauf aus der Wand oder aus dem Boden hervortreten. Bei modernen Heizungsanlagen kommen beide Anordnungen zur Anwendung, d.h. die beiden Anschlussröhren sind beim unteren Teil des Radiators auf nur eine Seite paarweise , entweder vertikal ausgerichtet - d.h. aus dem Fussboden hervortretend - oder horizontal ausgerichtet - d.h. aus der Wand hervortretend - vorgesehen. Die vorliegende Erfindung soll eine Lösung schaffen, die für beide Röhrenanordnungen anwendbar ist.
• Der Radiator muss für die Reinigung einfache und sicher nach vorn abklappbar sein und muss gegen falsche Manipulationen gesichert sein. Insbesondere muss er in seinen unteren Stützgabeln allseitig festgehalten sein.
• Das Befestigungssystem muss die Anwendung des Ventils mit drehbaren Kammern erlauben, das vom Stand der Technik her bekannt ist, so dass alle bekannten Vorzüge dieses Ventils zum Tragen kommen, wie beispielsweise die Möglichkeit, den Heizkörper während des Betriebes der Heizanlage zu ersetzen.

This valve with rotatable chambers is ideal for use in accordance with the present patent application, but is not a necessary prerequisite for this. The aim of the present invention is namely to propose a device for fastening a radiator to a wall, which has the following properties:

• Attachment of a hinged radiator, regardless of whether the tubes for the flow and for the return come out of the wall or from the floor. In modern heating systems, both arrangements are used, ie the two connection tubes are provided in pairs on the lower part of the radiator on one side only, either vertically aligned - ie protruding from the floor - or horizontally aligned - ie protruding from the wall. The present invention is intended to provide a solution which is applicable to both tube arrangements.
• The radiator must be easily and securely folded down for cleaning and must be secured against incorrect manipulation. In particular, it must be held on all sides in its lower support forks.
• The mounting system must allow the use of the rotatable chamber valve known in the art so that all of the known benefits of this valve come into play, such as the ability to replace the radiator while the heater is operating.

These objectives are met with the system for fastening a Radiators on a wall according to the characterizing part of the claim 1.

The possibility of aligning the two half elements, which form the fastening element, both upwards, or both horizontally, or one horizontally and one vertically, allows the radiator to be inserted into the support forks from above if the connecting tubes are vertical and protrude from the floor, or horizontally from the side if the connecting tubes protrude from the wall and lie horizontally, and then block the radiator by rotating one half element by 90 ° relative to the other, so that it can be removed from the support forks is prevented on all sides. The main advantage of the system for fastening a radiator explained here is that the foldable radiator can be fastened independently of the orientation of the forward and return pipes. This solution also opens up a number of further interesting application possibilities which offer further special advantages and which are the subject of dependent subclaims 2 to 8, which are described below with reference to a few examples and are illustrated in the figures. They show:

• Figure 1 is a schematic side view of the device according to the invention with a position of the fasteners, which allows the insertion of the radiator for assembly from above.

In the figure, 1 denotes a radiator, which on the wall 2 To be fastened in the room. The floor is labeled 3. The radiator 1 can be of any type, since it is not of importance in the context of the invention is whether it is built from cast iron pipes or from steel pipes Radiator or a heating wall made of sheet metal, etc.

It is only important in this context that the radiator 1 in its lower part by means of two support forks 4 (only one of which is visible since the other is covered by the first as in the following figures), on the wall of the room wall by means of suitable ( but not shown) fixing elements are attached. The support forks 4, which are shown in detail in FIGS. 4 and 6, each consist of a carrier element 5, which is firmly anchored in the wall 2, and which has a circular seat 6 (cf. also FIG. 4, in which the support fork 4 is shown in the same position as in FIG. 1), in which a fastening element 7 is rotatably arranged. This in turn consists of two half-elements 7 'and 7 ", of which only the front half-element 7' is visible in Figures 1 to 3. The other, 7", is covered by the visible, as shown in Figures 4 to 6, which show the support forks 4 in a perspective view and help to better understand their composition. From the enlarged representations in these figures, in particular the two horseshoe-shaped ones, which are essentially mirror images of one another, that is to say as a disk with a half element 7 'and 7 "which extends up to an opening 8 in the middle, can be better seen. In this opening 8 4, the support zone 9 of the radiator 1 is shown schematically as a cylindrical pin attached to the side of the radiator, the diameter of which corresponds essentially to the width of the opening 8, so that it fits into the Opening 1 can penetrate when the two half-elements 7 'and 7 "are in their upwardly open position, as can be seen in the upper part of FIG. 4, and is placed on the semicircular part of the opening 8. The arrow f ₁ in FIG. 4 indicates the direction in which the radiator 1 is pushed in until the support zone 9 of the radiator has reached its correct assembly end position, shown in FIG. 2, in which the radiator position is then blocked is how this is explained below.

The half-elements 7 'and 7 "are then rotatable against each other any kind connected, preferably in the following and below Referring to Fig. 7 shown type. The half elements 7 'and 7 "can assume three essential positions according to the invention, to perform the following different functions:

In a first position, shown in FIG. 4, the two half-elements form 7 'and 7 "an upwardly open opening 8 for the supporting zone 9 of the Radiators 1. In this position, the radiator, as the arrow fi indicates, be inserted vertically from above into the support forks 4. This position is advantageous if the tubes for the flow 10 and for the return 11th of the water emerge vertically from the floor 3, since the corresponding Connections (not shown) of the radiator 1 directly into the tubes 10 and 11 are "inserted", which facilitates the connection.

In a second position, shown in FIG. 5, the two half-elements 7 'and 7 "form a horizontally forward opening 8 for the support zone 9 of the radiator 1. In this position, the radiator 1, like the arrow f ₂ indicates horizontally from the front into or out of the support forks 4. This position is advantageous for the same reason mentioned in the description of Fig. 4 if the tubes for the flow 10 and for the return 11 of the water are horizontal emerge from the wall.

Finally, the half-elements 7 'and 7 "in one shown in FIG. 6 third position a locked seat for the support zone 9 (only dashed shown) of the radiator 1 (also shown only in dashed lines). In this position, the radiator is locked on all sides, since after one rotation one of the half elements 7 'or 7 "by 90 ° with respect to the other Half element of the fastening element (for example by turning either of the half-element 7 "shown in FIG. 4 by 90 ° counterclockwise or the half element 7 'shown in FIG. 5 by 90 ° in Clockwise) the opening 8 both above (through the half element 7 "in 6) and also at the front (by the half element 7 'in FIG. 6) is so that the support zone 9 of the radiator 1 is enclosed on all sides and only one rotary movement or folding movement around its axis can perform.

Thanks to the inventive design of the support forks 4 with the two Half elements 7 'and 7 "can be used for the installation and removal of the Radiators ideal conditions are created, be it that the tubes 10 and 11 are aligned vertically or horizontally, as well as to ensure the all-round locking of the radiator 1, which, however, in such Foldable remains that the radiator 1 is not from its support forks can be removed without first fitting the half-elements 7 'and 7 " have been discontinued.

In Fig. 1, the upper hook 12 is then shown, which when the Radiator 1, as shown in FIG. 2, is mounted on the wall, in the counter hook 13 hangs in and the radiator 1, which rests on the support forks 4 is supported and held therein by the half elements 7 'and 7 " prevents it from tipping forward. According to a first preferred Embodiment of the hook 12, it is firmly attached and can only be released be released when the radiator 1 from its lower support forks becomes. In this solution, the radiator 1 is, for example, from above the support forks 4 arranged as shown in Fig. 4 inserted, and during the last part of the lowering path also engages the hook 12 in the counter hook 13 a. Once the support forks 4 in the manner described above are locked, the radiator is enclosed on all sides, i.e. there is none Danger more that it unhooks from the upper hook, because the whole radiator would have to be raised after the water pipes separated from it and the half elements 7 'and 7 "as shown in FIG. 4 in their appropriate positions have been rotated. This solution therefore offers greatest possible security against the danger of unhooking and unfolding The Radiator 1. This can be of great benefit when you have the urge to play Considered by children for whom trying to unhook radiators and tipping can be a fun game. This solution with the Fixed hooks offer the greatest possible security against the Risk of tipping over, but it is not in terms of convenience ideally what the possibility of removing the radiator 1 from the wall concerns. This is because the radiator must be pulled out of the support forks 4 the tubes for the flow 10 and the return 11 of the Water can be removed.

To gain a special advantage in this regard, see Another preferred embodiment of the invention that the radiator 1 below a connection valve 14 for the flow pipe 10 and for the return pipe 11, which - shown schematically in FIG. 1 - by one horizontal axis is rotatably mounted on the long side of the radiator. A similar solution is known from prior art patents known, for example from the already mentioned patent application EP-A-0492957 - which, however, only because of their disadvantages already mentioned limited for use in a system according to the invention - and, but ideally suited - from the European patent application from the same applicant with the number EP-A-95810048.9 and the Registration date from January 21, 1994. The application of such a valve with rotatable chambers, the structure of which has already been explained here and therefore no further explanation is required, allowed after unhooking the hooks 12/13 a folding down of the radiator, provided, however, that the center of the circular seat 6 in which the fastener 7 can rotate, according to the invention with the axis of rotation (not shown) of the connection valve 14 of the radiator 1 matches without the tubes 10 and 11 removed and the support forks 4 opened have to.

In this latter case, and according to a further preferred embodiment of the invention, the upper retaining hook 12 is against the side Tilting formed as a movable hook (not shown) that released can be overcome by a resistor or a safety device (e.g. a pin or cotter pin) is loosened. A movable hook similar Kind with a spring, which is also suitable for use in the frame suitable for the present invention is, for example, in the published German patent applications DE-A-4236231 and DE-A-4129299 shown so that no longer explanations are necessary here. A safety device for such a releasable hook that like unauthorized opening Avoided by children, for example, can contain a locking pin or any other known element. Important in this is preferred Embodiment of the invention according to claim 5 only that the radiator 1 forward to the position shown in FIG. 3 can be folded down, for which only the hooks 12/13 can be released need without the radiator being lifted out of its seat in the support forks 4 must become.

3 is a further preferred embodiment of the invention shown, according to which the support forks 4 a limiting stop surface 15, against which a stop surface 16 of the radiator 1 strikes, when the latter is folded forward into an inclined position. Of the Advantage of this solution, in which the support fork 4 takes on a further function, i.e. forms the required stop, which limits the folding down obviously seen in its simplicity.

According to a further preferred embodiment of the invention, the subject of claim 2 and is shown in Figures 4 to 6, are the two half-elements 7 'and 7 "each with two retaining tongues 17 (from which only that of the half-element 7 'is visible in FIG. 6, since that of the Half-element 7 "hidden on the opposite side of this element is, the two half-elements 7 'and 7 "essentially mirror images are trained). Furthermore, the support element 5 has on each side two recesses on the center of rotation of the two fasteners 7 'and 7 "arranged at a central angle difference a of about 90 ° and in which the retaining tongue 17 of each of the half elements 7 ' and 7 "engages and the latter in one of the two positions provided holds on. 4 shows how the retaining tongue 17 of the half element 7 'in the recess 19 below engages and holds: in this Position is the opening of the half-element 7 'upwards. Also the (not visible) retaining tongue of the other half element 7 "engages in the Corresponding (not visible) recess in the supporting element 5 a. 5, on the other hand, the holding tongues 17 of the two engage Half elements 7 'and 7 "in the recesses on the side 17 so that the opening 8 is open towards the front. In the other position 6 engages the retaining tongue 17 of the half-element 7 'in the recess 19, while the other half element is arranged so that its Retaining tongue engages in the lateral recess 18 (not visible). The Retaining tongue 17 and the recesses 18 and 19 thus serve the stable Ensure the location of the half-elements 7 'and 7 "and their unintended Rotation, e.g. under the influence of vibrations, to avoid the could free the radiator from its corresponding support fork. The Retaining tongues 17 and the recesses 18 and 19 thus represent securing elements To twist a half element 7 'or 7 "is only that Retaining tongue 17 by pushing away or by slight elastic deformation to lift out of its recess 18 or 19, the half-element as far it is to be turned that the retaining tongue does not automatically move into the other one Grips recess and holds.

According to another preferred embodiment of the invention, which in 7, the two half-elements 7 'and 7 "are rotatable by means of one on the one half element 7 'or 7 "(e.g. in FIG the half-element 7 ') attached to the ring of hooks, that they can be twisted against each other, the hook 20 in a ring of recesses 21 in the other half element 7 " or 7 '(in FIG. 7 e.g. in the half element 7 "). The ring of the recesses 21 can, in the simplest case, as shown in FIG. 7, from one single rigid collar, in which the individual elastic hooks engage the wreath of hook 20 and hold on. At this The half-elements 7 'and 7 "are very simple on the embodiment Mount the support element 5 so that the two half-elements 7 'and 7 " can be joined together in a cost-effective manner and with ease can be rotated against each other, but great reliability their connection is ensured.

According to another preferred embodiment of the invention provided that the support forks 4 and / or the half-elements 7 ' and 7 "can be made of plastic using the die casting process Embodiment is also connected to the possibility that is not in the figures shown but is obvious to the expert, the elements in lightweight construction to produce from plastic, namely the support forks 4 and Half elements 7 'and 7 ", with any recesses to reduce weight can be provided according to the requirements for strength and robustness which such elements must have are. The use of plastics offers the advantage of elastic properties of the material to be able to use individual construction elements to give the required elasticity, such as the Retaining tongues 17 and the hook of the wreath of hooks 20 which are related with some preferred embodiments of the present invention have been described.

It is essential to the present invention that support forks 4 are used that can be used in three well-different positions, one of which allows insertion of the radiator 1 from above, one others allow the radiator 1 to be mounted horizontally from one side, while in the third position of the support forks the radiator is locked on all sides is. This basic solution is described and with reference on an embodiment of the support forks 4 has been shown in more detail. Nevertheless, it should be emphasized that other embodiments of the described Support fork 4 are possible, which meet the aforementioned requirements also meet and therefore fall within the scope of the present invention.
