Standing console for a radiator

The invention relates to a stand bracket for a radiator, in particular for a multi-panel radiator having at least two plates, consisting of a base part, a stand pipe that can be inserted or placed on the base part and has a preferably rectangular cross-section, and at least one pipe profile piece that surrounds the stand pipe and can be connected to it and has a support for the radiator or parts of it, the support forming a surface that is preferably horizontal in the operating position and has openings and/or cuts for receiving fastening means for mounting the bracket on the radiator or on parts of it and/or supply lines for the radiator.

Such a stand console is already known from WO 94/21970.

Problems can arise with the well-known stand console if the radiator and the stand console are not exactly matched to each other. This is especially true for

Multiple plate radiators in which the at least two plates are spaced apart from one another at different distances. In these cases, it was previously necessary to provide support devices adapted to the respective distance between the two plates, such that the lower seams of the radiators or the inclined surfaces extending from these seams are supported in a suitable manner by the edges of the support, as shown in Fig. 5 of the citation. If the distance between the two radiator plates of a multiple plate radiator becomes larger, it can happen that the plates slide past the support; if, on the other hand, the distance is too small, the inclined surfaces used for support no longer find a suitable supporting edge.

One possible solution would be to provide a support adapted to the distance between the radiator plates, but this would have the disadvantage that a relatively large stock of different support devices would be necessary.

The object of the invention is to enable adaptation to different distances between plates of a multi-plate radiator with less effort, whereby the other advantageous properties of the known standing console should not be impaired.

This problem is solved by placing a plastic plate on the surface with a width that is either smaller than the width of the surface of the support, thus leaving support areas of the surface free, onto which the seams of the panel radiators can be placed, or is equal to or (preferably) larger than the width of the surface of the support, in order to be able to engage the inclined surfaces of the panel radiators close to their grooves.

In this way, adaptation to different

The distances between the plates of a multi-plate radiator are achieved in a much simpler and cheaper way than would be the case if the entire pipe profile piece with support plate had to be replaced or kept in stock in different widths. Instead, only a plastic plate adapted to each individual case is provided, which is placed on a fixed metal support with an attached pipe profile piece.

According to a further development of the invention, the plastic plate has openings for receiving the pipe profile piece or the pipe as well as a slotted hole corresponding to a slot in the support surface for receiving a clamping screw.

In this way, a one-piece plate can be used that is easy to manufacture and has all the necessary openings to allow sufficient air to pass through, but at the same time also allows the pipe or pipe profile piece to pass through easily.

The fastening means for holding the radiator or projections extending from the radiator, such as connecting pipe areas, can be a Z-profile hook that has an opening or thread for the clamping screw at one end of the leg and a clamping area, possibly with a cut with a semicircular end profile, at the other end of the leg. This simplifies the fastening process because only one fastening means is required instead of two to secure the radiator at one end.

It may be advantageous to modify the plastic plug provided on the well-known stand bracket for holding the radiator at its upper end in order to achieve adaptability to different distances between the plates of a multi-plate radiator.

According to a further development of the invention, it is advantageous if a stand bracket of the above-mentioned type, in which the upper standpipe end has a T-shaped plastic plug which clamps onto surfaces formed by the radiator, such as cavity inner surfaces or plate inner surfaces, is characterized in that the T-beam of the T-shaped plastic plug has a width which can be adapted to the distance between the cavity inner surfaces or plate inner surfaces, in particular is approximately equal to the width of the plastic plate.

This arrangement can be further developed in such a way that the plastic plug has a thread or nut aligned with the axis of the standpipe to accommodate a screw bolt that extends through the pipe and with which the plug can be pulled into the pipe with its base. This has the advantage that the radiator can be easily secured against being accidentally lifted off the stand bracket. According to a further development of this design, the T-shaped plug forms a slot that starts from the T-beam and extends into the base. An axial hole can be provided in the slot area of the base to accommodate the screw bolt. However, the axial hole can also form a thread for the screw bolt. The thread can in particular be formed by a pressure part that can be placed on the T-beam. The thread of the pressure part can be formed by a metal nut that is pushed or injected into it.

If the slot widens in a funnel shape in the direction away from the base and the thread is formed by a wedge that can be inserted into this funnel, it is also possible to clamp the plastic part between the plates of the multi-plate radiator through the effect of the screw bolt or even to make an adjustment to different distances between the two radiator plates.

According to a further development, the thread can be formed by a pressure part resting on the two sections of the T-beam.

The top view contour of the foot of the T-shaped plug can taper towards the door beam.

The head of the screw bolt can rest on the front edges of the lower end of the pipe. In this case, it is advantageous if the head of the screw bolt is supported by a washer whose diameter essentially corresponds to the outside cross-section of the pipe in the support area, while the diameter of the head is smaller than or at most equal to the inside cross-section of the pipe (in the support area).

The slot can also extend close to or to the foot end and form a predetermined breaking point or a film hinge there. This ensures that the plastic plug is one piece during assembly, but at the same time allows a large adjustment range for different distances between the radiator panels.

The special design of the bolt that holds the plastic plug makes it possible to insert the standpipe, including this bolt with head, into a base after the standpipe has been mounted on the radiator, without the head of the bolt getting in the way.

Even after the foot has been mounted, the bolt can still be tightened from below through a foot opening.

The invention is explained in more detail below using embodiments shown in the drawings.

the individual parts of the arrangement according to Fig. 6.

In Fig. 1, a standing console 10 can be seen, which is present in duplicate and holds a radiator 12. The radiator 12 here consists of two plates 13, 15 which are spaced apart by a distance A from one another and which have both a flow connection and a mechanical connection via pipe connections 17. A connecting piece 19 extends downwards from this pipe connection 17 in order to connect, for example, to a pipe connection piece coming up from the floor.

«J » <LS ·· &iacgr;-&iacgr; UU

The stand console has a base part 24, ■consisting of a base plate 26, which can be screwed to the floor using screws inserted through openings 30, for example, and from the top of which a pipe section 28 extends, which is welded to the plate, for example, into which pipe section 28 a standpipe 32 is inserted. Pipe section 28 and standpipe 32 each have a rectangular cross-section.

The standpipe supports a support 34, consisting of a pipe section 40 that can be pushed onto the standpipe 32, which in turn is welded to a plate 42 that forms a horizontal surface, which plate 42 has round openings 46, elongated holes 44 and a lateral cut 48 for receiving a connecting pipe 19, with plastic hooks 58 that are guided within the elongated holes 46 and can be secured by means of clamping screws 60 and can be placed over the pipe connection 17, whereby the stand bracket 10 can be attached to the radiator 12.

In order to achieve the greatest possible tipping safety, a T-shaped plastic plug 68 is inserted into the front cross-section of the upper end of the standpipe, which clamps onto surfaces formed by the radiator 12, such as the inner surfaces of the cavity or the inner surfaces of the plates, not shown here.

The other foot shown on the right in Fig. 1 has a similar structure, with the only difference that the incision 48 is missing.

In Fig. 2, a support 134 modified according to the invention can be seen, which is shown again in an exploded view in Fig. 3. The support 134 designed according to the invention therefore consists of a pipe section 40 similar to that in Fig. 1, which can be fixed, for example, by means of a

Clamping screw.can be attached to a standpipe 32, not shown here, in a height-adjustable manner. A steel sheet plate 142, which has a centrally arranged elongated hole 144 aligned with the length of the plate and also round openings 146, is spot-fixed or welded to the pipe section 40, for similar purposes as in the construction shown in Fig. 1. In addition, a plastic plate 35 with a width B is placed on top, which is, for example, smaller than the width C of the surface of the support, whereby support areas 37 of the surface of the plate 142 remain free, on which, for example, the seams 31 of the radiator plates 13, 15 can be placed. However, alternatively, this plate can also be the same width or larger than the width of the surface of the support, in order to then be able to engage the inclined surfaces 41 close to the seam of the radiator. If the protruding surface 37 is very short, the side surfaces can also engage close to the seams in the construction shown in Fig. 2, in which case, for example, the seam areas could extend past the front edges 41 of the panels. The advantage of engaging the plastic panel is the soundproofing achieved thereby.

A further improvement compared to the design of Fig. 1 is that instead of the two hook-shaped holders 58 shown in Fig. 1, only one hook 158 is provided, which here has a double L shape (or Z shape) and with its one end leg 45, which may have a threaded opening, with the help of a screw 47, which is passed through an elongated hole opening 144 in the plate 142 or through a corresponding elongated hole opening 244 in the plastic plate 35, and with which the hook 158 can be fixed to the plate 142 or 35, namely due to the elongated hole in such a position that the other leg 49 of the hook 158 in turn similarly as already described over

&iacgr;·&mdash;·&mdash;»-

a pipe connection 17 or a similar connection area between the two plates 13, 15 and thereby holds the radiator to the stand bracket. In order to be able to accommodate a pipe connection that points upwards, if necessary, the leg 49 also has a notch 148 that may be semicircular in shape at its end.

For stability reasons, it will usually be advantageous not only to attach the pipe section 40 bluntly to the steel plate 142, but rather to guide it through a correspondingly adapted opening in the steel plate 142 by a certain amount, which results in increased stability. In adaptation to this area 51 passing through, the plastic plate 35 also has an adapted opening that is able to accommodate this stump 51. Accordingly, the plastic plate 35 will also be provided with openings 246 that are aligned with the openings 146 in the steel plate 142 and thus allow warm air to pass through.

As can be seen from the assembly drawing in Fig. 2, the longitudinal extension of the area passing through the pipe section 40 is slightly larger than the thickness of the plastic plate 35.

The plastic plug 68 already mentioned in connection with Fig. 1 has also been improved to increase stability and to adapt to changing distances between the two radiator plates 13, 15 according to Fig. 4, 5, 6 and 7. Thus, Fig. 4 shows in a perspective view the standpipe 32 with a plastic plug 168 inserted into its upper end, which has a thread or nut 55 aligned with the axis of the standpipe, see Fig. 12, for receiving a screw bolt 57 extending through the standpipe 32, with which the plug 168 is connected to

its foot 59 can be pulled into the end of the pipe, as can be seen in Fig. 4.

In particular, Fig. 10, a perspective view of the plug, shows that this T-shaped plastic plug forms a slot 63 starting from the T-beam 61 and reaching into the foot 59. In the slot area of the foot there is also an axial bore 65 into which the screw bolt 57 can be received. This axial bore can be provided with a thread for the screw bolt. In the embodiment shown, however, the thread is formed by a pressure part 67 that can be placed on the T-beam 61, or by a metal piece or nut 55 inserted into an opening 69 in this pressure part, see Fig. 11 and 12. The pressure part has a wedge shape in axial section, whereby the wedge surfaces 71 can be inserted into the slot 63 of the T-shaped plastic plug, whereby the slot 63 provides a certain adaptation to this wedge shape through a funnel-shaped extension at its upper end. Laterally projecting walls 73 form a guide channel on both sides of the wedge surface 71, which is able to accommodate the T-beam ends of the plastic plug 168 and prevents the pressure part 67 from slipping off the plastic plug 168, thus making assembly easier, as long as the pressure part 67 and the plastic plug 168 are not aligned with one another by means of the screw bolt connection 57. Furthermore, the arrangement of the side walls 73 prevents the pressure piece from rotating when the screw bolt 57 is screwed into the pressure part from its head 75 in order to pull the pressure part 67 towards the plastic plug 168, which in turn pulls the latter with its foot 59 into the end pipe 32, see Fig. 4.

The head 75 of the screw bolt 57 is supported by a washer 77 on the lower end edges 79 of the standpipe 32, see Fig. 6, a view obliquely from below of the arrangement.

-11-

As the screw is tightened, the lower surfaces 81 of the T-beam 61 initially rest on the end surfaces 83 of the upper end of the standpipe 32, as also shown in Fig. 4. In this position, which is shown in Fig. 4, but with the screw 57 with its head 75 resting on the washer 77 and this in turn resting on the end edges 79 of the lower end of the standpipe 32, in such a way that the washer 77 or the head 75 does not protrude beyond the plane of the outer surface of the standpipe 32, the lower end of the standpipe 32 can be inserted into the pipe section 28 of the base part 24 and a corresponding pressure screw can be tightened in order to fix the standpipe 32 in the base. ,

Now the standpipe 32 with its still narrow T-shaped plastic plug 168 arranged at the upper end can be inserted into the radiator 12 from below as shown in Fig. 4, whereby the distance E between the two end faces 85 of the T-beam fits between the inner surfaces of the two plates 13, 15.

Before placing the foot or before attaching the T-shaped plastic plug, it is advisable to first push the support 34 onto the standpipe 32, after which, after inserting the stand console thus completed, it can be secured by slipping the hook 258 (or corresponding hook 58 according to Fig. 1) over a plate connection between the plates 13, 15, for example in the form of a connecting tube 17.

If the radiator 12 is upside down when being inserted, which is particularly useful, and the base part 24 has a through-opening for receiving the standpipe 32, the head of the screw 75 is still accessible through this opening in the base 24 and one can therefore, for example,

a screwdriver, tighten the screw bolt 5 7 further, whereupon the pressure part 6 7 slides with its wedge-shaped area into the slot of the T-shaped plastic plug and in doing so pushes the T-beam parts 87, 89 separated by the slot apart, as can be seen in Fig. 5. This increases the distance between the end faces 85 and any play that may still exist between these end faces 85 and the surfaces of the radiator plates is taken up and an adjustment to any differing distance dimensions is achieved. By tightening further, it is even possible to create a clamp between these radiator plates and the two T-beam parts 87, 89, so that the stand console is not only firmly connected to the radiator at its lower end, but also creates a stable lock at its upper end through a clamping effect.

After inserting the appropriate number of such stand brackets and clamping them at the lower and upper end of the respective standpipe 32, the radiator (each still with outer packaging) can then be brought to its installation location and screwed to the floor with the stand brackets mounted on it, whereby the head 75 is then no longer accessible, which can provide additional security against the radiator being accidentally and unauthorizedly lifted off.

In order to facilitate the pushing apart of the two parts of the T-shaped plastic plug 168 from the position shown in Fig. 4 to the position shown in Fig. 5, it may be expedient to move the slot 63 close to the lower surface of the foot 59 in order to leave only one material web 89 behind, which, if the material properties of the plastic are appropriate, works as a film hinge and allows the two halves of the T-shaped plastic plug to be folded apart around this

- 13 -

Hinge 89 enables this pivoting movement around the film hinge 89. In order to facilitate this pivoting movement around the film hinge 89, it is also advantageous if the cross section of the foot 59, starting from, for example, a short straight piece 93, which may, for example, rest against the inner narrow surfaces of the tubular profile of the standpipe 32, tapers through inwardly recessed inclined surfaces 91, so that the two parts of the T-piece 168 can pivot around the film hinge 89 by a dimension that corresponds to the recess angle of the surface 91.

Instead of providing a film hinge, a predetermined breaking point can also be provided at point 89, for example in the case of relatively hard or brittle plastic material, so that when the T-shaped plastic plug 168 is tightened when the stand bracket is clamped in the radiator, the two parts break apart at point 89 and make the plug into two parts. Since these parts are nevertheless held in position by the pressure part 67 with the side walls 73, this breaking is not disadvantageous.
