Disclosed is a mounting unit such as a standing bracket (10) or window ledge support (110) for single- or multiple-layer panel heater units (62, 162) with convector plates. The mounting unit consists of a base plate (26) or window ledge support, a standing tubular element (32) being held in said support and preferably of rectangular cross-section, and a holding device (34) for the panel heater unit, said holding device being fitted on the tubular element so as to slide and capable of being secured to the tubular element by a sleeve (35) which grips the pipe and by a locking screw (36) extending from the sleeve to the tubular element. A thread (37) for the locking screw is formed from one side wall of the sleeve (35) to one face of the sleeve; a strip or wing (44) parallel to the sleeve originates from at least the contiguous side wall of the sleeve perpendicular to the thread and the cross-section of the said strip can fit into the vertical air passage space (68) formed by the convector fins or plates (60) of the heating unit (62).

Description

Bracket, such as stand bracket for single or multi-layer panel radiators equipped with convector sheets

TECHNICAL AREA

The invention relates to a holder, such as a stand bracket or window sill support or the like for single or multi-layer panel radiators provided with convector sheets, consisting of a base plate or window sill holder or the like, a standpipe of rectangular cross-section held in or by it, and a holding device for the panel radiator that is slidably held on the standpipe and can be fixed to the standpipe by means of a sleeve that surrounds the standpipe and a clamping screw that extends from the sleeve to the standpipe.

STATE OF THE ART

A standing console as described above is already known from WO 94/21970. The standing console known from this publication already has many advantages that other standing consoles do not have, in particular the radiator can be installed without having to remove its packaging first. This prevents the radiator from becoming contaminated, for example by paint splashes or plaster residues, when tradesmen are still working in the room in which the radiator has been installed. The packaging of the radiator still in place means that it is not necessary to protect the installed radiator against such contamination with covering film or similar.

However, in many cases the disadvantage is the rather complicated installation, which requires the tightening of three different screws, for example, in order to fix the holding device at the correct height of the

—2—

standpipe and to attach the radiator to the holder using special hooks.

The object of the invention is to further develop the known stand console so that the standpipe can be manufactured more cheaply and the assembly is further simplified.

The problem is solved in that a thread for the ■9 clamping screw is formed on a side wall of the sleeve near one of its front ends, and in that a (straight or cranked) strip or wing extends from at least one of the adjacent side walls which are perpendicular to it and runs parallel to the sleeve axis, the cross section of which can be accommodated with a tight fit in the vertical air passage lumen formed by the convector sheets or slats of the radiator to be attached.

Instead of providing hooks, as in the prior art, which are either placed over water supply pipes or over retaining tabs, here, according to the invention, assembly is carried out by inserting the strip or wing into one of the /φ convector sheets, whereby due to the special arrangement of the clamping screw in relation to the sleeve extension, during the tightening of the clamping screw to fix the sleeve at the desired height of the standpipe, the sleeve also tilts in relation to the standpipe due to the play that is always present, thereby pushing the wing or strip out of the exact alignment with respect to the standpipe and thereby clamping the radiator between itself and the standpipe and thus fixing it.

In most cases, one blade is sufficient, but if a particularly even clamping is required, or if the weight of the radiator is particularly high, or the load-bearing capacity of the blades is not very high, it may be advantageous to use more than

to provide a wing, preferably two wings, which allow the standpipe to pass between them and are arranged at such a distance from each other and from the standpipe that they can be accommodated in two adjacent lumens formed by the convector fins and, when the screw is tightened, lie against the inner surfaces of the fins in such a way that at the same time the standpipe is pressed against the panel radiator from which these fins extend.

Of course, a different grid pattern can also be used, so that, for example, the two wings can enter into slat lumens other than those closest to them.

The weight of the radiator is preferably supported by the crank surface of the blades being formed as a support surface for the lower edge of the slat extending from the radiator.

For sound insulation or to avoid scraping noises when the radiator expands due to heat, a plastic part can be used as an intermediate bearing in the area of the crank, so that the metal slat of the panel radiator does not rest on the metal crank area, but a plastic part is arranged in between.

As in the current state of the art, the upper end of the standpipe can be closed with a plug that has projections or an edge that extend to the side. This allows the radiator type in question to be precisely adjusted and aligned to the cross-section of the standpipe, while at the same time, if the plug is made of plastic, sound insulation is achieved.

The standpipe according to the invention is particularly well suited

• · * &Lgr; · * «14

for a specific type of radiator in which vertically running slats with a rectangular profile extend from one side of a panel radiator through which water flows, with a distance between them that is sufficient to accommodate the standpipe in at least one orientation. Such radiators are installed in such a way that the side of the panel radiator with slats is mounted facing the wall.

This radiator, consisting of a plate and convectors attached to one side, is referred to as radiator type 11. If another plate without convectors is attached to the convectors extending from one plate, this is type 21, which can also be mounted with the stand bracket according to the invention.

There is also a type 22, which consists of two plates and two rows of convectors extending from the plates. A type 33 can also be installed, consisting of three plates and three convector areas extending from these plates.

On the other hand, the newly created stand console cannot be used to mount type 10, which consists only of a plate without any convector slats attached to it. For this type 10, the console is suitable according to the state of the art.

For types 11, 21, 22, etc., however, the stand bracket according to the invention with its particularly simple construction and assembly options is significantly more cost-effective, especially since both the height adjustment and the fastening between the standpipe and the holder, as well as between the holder and the radiator, can be carried out using just one screw. As with the state of the art, the radiator can also be assembled in its packaged state.

By using a plug at the top end of the standpipe, it is possible to get by with just one length of standpipe for all radiator heights, since the alignment of the upper part of the radiator is carried out by the plug that is supported between the slats. The length of the blade determines its deflection when the tension screw is tightened. It is advisable to adjust the length of the blade to the pressing force of the screw, so that a longer blade extension is possible for a larger pressing force of the screw. On the other hand, with a large pressing force of the screw, the deflection required in the area of the screw is smaller, because this results in a larger deflection at the free end of the blade due to a larger lever arm of the blade with a longer blade length. This also makes it possible to accommodate different dimensions of convector sheets from different manufacturers.

BEST WAYS OF CARRYING OUT THE INVENTION

In Fig. 1, a stand console 10 can be seen, with a foot part 24, which in turn consists of a base plate 26, which could be screwed to the floor using openings not shown here and from the top of which a pipe section 28 extends, for example in that this pipe section is welded to the plate 26, into which pipe section 28 a standpipe 32 can be inserted (or alternatively plugged over it). The standpipe 32, like the pipe section 28, has a rectangular cross-section, but another prismatic cross-section that prevents rotation is also conceivable. A round cross-section would be less favorable, but also possible.

A support or holding device 34 is carried by the standpipe, as shown again individually in Fig. 2c, or a holding device 134 according to Fig. 4. This holding device 34 comprises a sleeve 35 which encloses the standpipe 32 with only a small amount of play, such that the sleeve 35 can be pushed on and off the standpipe. Preferably on a narrow side of the rectangular

·· tr»·

Profile of the sleeve 35, a thread 37 for a clamping screw 36 is provided at or near the upper end of the sleeve, where the thread 37 can be formed by the material of the sleeve or by a welded-on nut or the like. A welded-on nut provides greater stability when transferring the clamping force from the screw to the sleeve. The side of the sleeve 35 provided with the clamping screw has a certain amount of play 38 towards the standpipe, so that the sleeve 35 can perform a limited tilting movement with respect to the standpipe when the clamping screw 36 is tightened.

This tilting movement is transferred from the sleeve to a strip or wing 44 attached to this sleeve, see the arrow 42. The wing 44 has a crank 52 between its fastening area 46 on the sleeve 35 and on the free area 50 running at a distance from the broad side 48 of the standpipe 32, which on the one hand forms a support surface 54 in the crank area, and on the other hand leads to an increased distance 56 between the broad side 48 of the standpipe 32 on the one hand and the surface of the wing 50 facing this broad side on the other hand.

In Fig. 3, a perspective view of a panel radiator 72 can be seen, consisting of two plates 64, 66 arranged at a distance from one another, which are preferably made of sheet steel and are connected to one another in a watertight manner all the way around by means of a bend and a weld seam 58, whereby only the lower seam is shown here, while the other edges appear cut open.

Vertically aligned slatted sheets are welded onto the outer surface of the plate 64, which on the one hand form air ducts 68 that are open only at the top and bottom, essentially with a rectangular cross-section, and on the other hand form channels 70 that are open at the sides between them. The channels 68 and 70 have essentially the same, essentially rectangular cross-section with a cross-sectional width 72 and

a cross-sectional length 74. The stand bracket 10 connected to this radiator 62 or shown in Fig. 3 is now shown with its standpipe 32 pushed into the channel 70, which means that the width 172 of the standpipe 32 must be dimensioned such that it fits into the inner width of the channel 70. At the same time, it can be seen that the wing 50 is pushed into the channel 68 of the convector slats 60, so that the lower front end of one wall of this channel 68 rests on the support surface 54 of the wing 44, which is formed by the crank 52. Inserting the bracket shown in Fig. 1 to achieve the state shown in Fig. 3 thus only requires opening the packaging at the lower end of the radiator in order to expose the lower openings of the channels 70 and 72, respectively, after which the stand bracket according to Fig. 1 can be inserted with its end on the standpipe 32 into the channel 70 (or another corresponding channel) on the one hand and with the upper end of the wing 50 in the adjacent channel on the other hand.

Now a clamping screw 36, no longer shown in Fig. 3, can be screwed or tightened into a threaded hole visible at 3 7, after the correct position of the sleeve 35 on the standpipe 32 has been determined and the height of the radiator above the floor has been determined. This tightening or tensioning pivots the sleeve 35 and thus also the upper end of the wing 50 in the direction of the arrow 42 in the manner already described, i.e. away from the radiator plate 62 towards the slatted channel wall 76. This simultaneously presses the channel wall 78 of the channel 70 pointing towards the narrow side 140 against the standpipe 32, so that at the upper end of the stand bracket these slatted parts are clamped to the corresponding parts of the stand bracket. The clamping and friction forces that arise in this way ensure that the radiator is fixed in relation to the stand bracket in terms of axial movement.

The torque effect exerted on the stand bracket on the one hand and the radiator on the other hand is absorbed by the stand bracket's fastening to the floor, and by the second or further stand bracket fastening (not shown here) for the radiator, so that this torque effect does not cause interference.

Should this torque effect nevertheless be undesirable for some reason, a second wing can be provided according to an embodiment shown in Fig. 4, such that the two wings 44, 144 can be inserted into two preferably adjacent convector louvre channels 68, 168, while the standpipe not shown in Fig. 1 would be inserted into the open channel 70 between them. If the clamping screw not shown in Fig. 4 is now tightened, both wings 44, 144 move in the same direction, as shown in Fig. 1 by the arrow 42, but the torque is cancelled out by the symmetrical arrangement of the two wings 44, 144.

It has proven to be advantageous to arrange a plastic part, which can be seen in Fig. 2d, between the support surface 54 formed by the crank 52 and the heat fin that normally rests on this support surface in order to suppress sliding noise and also to avoid sound transmission. This plastic part is shown in Fig. 2 as being angled, but could also be shaped differently. It could be attached by gluing, by wrapping it around the wing in a U-shape, or, as shown, by the plastic part 78 having an outward-facing nose 80 with which it is inserted and locked into a corresponding hole or opening 82 formed by the wing 44 according to Fig. 2c.

Fig. 2e shows a perspective view of a plastic plug 84, which with its foot end 86 covers the inner

- 10 -

Cross section 88 of the standpipe 32 (see Fig. 2b) can be inserted with a press fit. The head part 90 protrudes over the foot part 86, whereby this head part preferably has a cross section that matches the external cross section of the standpipe 32, or can also extend beyond this in order to form, for example, a clamp connection within the channel 70 of the radiator fin arrangement if its inner lumen should be significantly larger than the external cross section of the standpipe 32. It would then be possible to adapt to different fin shapes of the radiator by simply replacing the plug 84.

The distance 56 according to Fig. 1 should be selected so that the wing 42 is located approximately centrally within the corresponding channel 68, with two wings 44, 144 being arranged accordingly in two adjacent inner channels 68, 168.

The pivoting movement in the direction of arrow 42 that occurs when jamming usually occurs without any special measures simply because the clamping bolt 36 is attached to the upper end of the sleeve 35. If this pivoting movement is not sufficient, the same could be achieved by narrowing the cross-section at the lower end of the sleeve 35.

The installation with the stand bracket shown is also possible for panel radiators that consist of two panel radiators 62 that are placed on top of each other with their slats so that smooth surfaces are created on the outside.

Because the plug 84 can be designed in such a way that it can rest against the walls of the channel 70, the standpipe length does not need to be so great that it reaches through the radiator. In this way, it is achieved that one bracket length is sufficient to mount radiators of different heights.

It is advisable to choose a screw with a ring cutter for the clamping screw 36, which digs firmly into the material of the side wall 40 of the standpipe 32 and thus enables a secure hold.

Fig. 5A and 6A show, in a view similar to Fig. 1, an embodiment in which the wings 144 and 244 are straight, i.e. not cranked as in Fig. 1. The wings 144, 244 are welded onto the sleeve 135, 235 at a slight angle (at an angle 142 outside the alignment with the standpipe axis). When the radiator is pushed on, the wings are essentially pressed into the alignment with the standpipe 32 and the sleeve 135 or 235 is tilted instead. If the upper clamping screw 236 (Fig. 6A) is now tightened, the axis 45 of the sleeve 235 is again partially pressed in the direction of the axis of the standpipe, whereby the wings 244 return to the pivoted-out position shown in Fig. 5A or 6A and clamp the radiator in the manner already described.

When tightened, the second (lower) clamping screw 336 increases the holding force of both the sleeve 135, 235 on the standpipe 32 and the wings 144, 244 on the radiator.

By allowing play in the sleeve 135, 235 in the direction of the narrow side of the standpipe, sufficient space can be created for the slat wall thickness between the standpipe and the blade, if the material thickness of the sleeve 135, 235 does not already ensure sufficient distance (56 in Fig. 1).

In Fig. 5A, the upper front edge 47 of the sleeve serves as a support for the radiator, in Fig. 6A a special flange 147 or attachment is provided.

Fig. 5B and 6B show plugs 184 with a sliding support strip 185 mounted thereon, which can be used to align the standpipe within the lamella lumen.

- 12 -

Fig. 7, which shows a somewhat enlarged holder similar to that in Figs. 5 and 6, shows this plug 184 in more detail and shows that it comprises a U-member 186, whose web 193 carries the support strip 185 and whose legs 187, 188 form a funnel-shaped opening at their ends, into which a wedge piece 189 is received, which pushes the legs apart when the wedge piece 189 is pulled between the legs 187, 188 by means of a screw 190 (only indicated) in order to clamp the plug 184 in the end of the standpipe 32. This screw 190 can be screwed into a thread of the wedge piece 189,

•which may be cut into the wedge piece, which is preferably made of plastic, or which may be formed by a metal nut inserted into a notch 191. The screw 190 can simultaneously fix this bar 185 with its head via an elongated hole 192 located in the support bar 185 so that it can be moved on the web 193.

Fig. 7 shows a holder in which at the lower end of the sleeve 435 on the side of the profile of the sleeve 435 opposite to the first thread 437, another thread 443 is provided for a clamping screw 441, preferably formed by a grommet projecting into the interior of the sleeve 444. The projecting grommet 443, or the screw 441 received by the grommet thread, serves to form a defined pivot point for the pivoting movement of the sleeve 435 and thus of the strips or wings 444 when the first clamping screw 436 provided for pivoting the wings or strips 444 with respect to the standpipe 32 is tightened in the thread 437.

A further advantage of this arrangement is that the screw 441 can be used to initially fix the height of the sleeve 435 by tightening this clamping screw 441 so that it grips and clamps the standpipe 32, after which the other clamping screw 436 is then tightened in order to now pivot the

Strips or wings 444 clamp the radiator (or its slatted interior or the like, into which the standpipe with the wings or strips 444 is inserted) between the one standpipe narrow side 55 on the one hand and the oppositely aligned edges 5 7 of the wings or strips 444 on the other hand, relative to the standpipe axis.

For better adaptation to very different radiator fin inner dimensions, it can be advantageous to provide an opening (or recess) 45 near the free end of the strip or wing 444, in which a retaining lug 47 extending from one leg 50 of an L-shaped adapter 49 (see Fig. 9) is received, which adapter 49 grips the narrow edge 57 of the strip or wing 444 used for clamping purposes with its other leg 53 and thereby lies with this leg 53 between the strip edge 57 and the radiator fin inner surface when the wing is pivoted. Depending on the thickness of the intermediate L-leg 53 of the adapter 49, different radiator dimensions can be detected. Since the adapter piece 49 is designed to be removable, it can be replaced, and the console can therefore be used for different radiator dimensions without much difficulty.

The plastic support 178 is designed here as a ring that surrounds the pipe 32, with protruding stop lugs 193, which, when the support 178 is pushed up, align the wings 444 with the pipe axis and thus enable the radiator to be pushed over the bracket without being hindered by wings 444 that are swung out too far. When the radiator is pushed on further, it then presses the support 178 into the position shown in Fig. 7, in which the movement of the wings in the swing-out device, arrow 194, is no longer prevented.

Slats of a radiator 162 of the type discussed here, and if the foot 24 &zgr; is replaced, for example, by a support 124 for a window sill or the like, the arrangement shown in Fig. 9 results. By pushing in and pulling out the standpipes 132 with respect to the wings 344, which can be supported with an edge 247 or a crank 152, for example on a slat edge and are therefore fixed in height, the desired height of a window sill 92 can be set, whereupon by tightening screws 336 or 441 and 436 in the manner already described, both the standpipe 132, 32 with respect to the wing ^ or 444, and the standpipe 132, 32 and wings 344, 444 with respect to the radiator slats and thus the height of the window sill are fixed.

The radiator itself may be mounted on the floor in a similar way to that described above, whereby the same or (especially with long standpipes) other slat cavities may be used for the stand bracket or window sill support, or the radiator may be mounted in a completely different way.

The window sill support 124 can be connected to the standpipe by a φ clamp connection, e.g. as shown in the foot 24 in Fig. 3, or welded to this standpipe, as shown in Fig. 9. The claw width of the window sill support can then be conveniently adjusted to the width of the window sill.

COMMERCIAL EVALUATION

The device can be used commercially in heating technology.
