Description

502 940 2 Radiators of this type are often fitted with protective plates along their vertical edges and at the top.

This means that if a fastening device for the radiator's mounting on the base is located hidden inside between the sub - radiators, it cannot be eaten from the end sides of the radiator and its upper side.

Furthermore, the radiators are usually delivered pre-painted and packaged in a protective packaging to the workplace.

During installation, the aim is to maintain the packaging on the radiator, preferably even after the radiator has been installed. Consequently, it is a strong desire that the fastening device should be able to be inserted straight through the packaging at the underside of the radiator and fastened in the radiator without the packaging being unnecessarily damaged or removed.

DE 4 323 199 A1 shows a fastening device intended for attaching radiators of the current type. This fastening device comprises a vertical pipe, which must be dimensionally cut depending on the design of the radiator in question. The fastening device has lower brackets for co-operation with the transverse pipes, which connect the two sub-radiators included in a double radiator. Furthermore, the device at the upper end has a fitting piece, which is intended to clamp out between them between the two sub-radiators.

The construction according to DE 4 323 199 is impractical and complicated to use, can not be used universally regardless of the radiator's measured and the appearance of the convector plates and also requires major interventions in the radiator's packaging to be able to be used.

WO 94/04875 discloses another type of fastening device for the current radiator construction. This fastening device has a fixed and a pivotable clamping jaw which are designed to grip around the lower, mainly horizontal water channel of the radiator. The jaws expand away from each other and are fitted from the inside towards the sub-radiators immediately over their lower water channel.

The construction according to WO 94/04875 is adjustable according to the dimensions of the radiator and can work well in many contexts in that no parts have to be replaced depending on the type or dimensions of the radiator, but has certain limitations due to the convector plates that often occur on radiators of this type. In some cases, the space for using the fastener is simply too small.

PROBLEMS The object of the present invention is to design the device indicated in the introduction so that it becomes universally usable for different types of such radiators which have at least two at some distance located, substantially vertical surfaces, preferably radiators, which comprise at least two sub-radiators. The invention further intends to design the device so that it can be used hidden inside between the sub-radiators or inside a convector plate on a single radiator in that it can be pushed in through a hole in the packaging at the lower edge of the radiator and mounted in place without layer or any cover plates must first be removed.

Furthermore, the invention intends to provide a device which is adjustable in height so that a radiator can be mounted at different heights above the ground. Finally, the invention also intends to provide a device which is not limited to its use due to a special design of the radiator convector plates, but which can be universally used with most radiators of this type in question.

TROUBLESHOOTING The object underlying the invention is achieved if the initially indicated device is characterized by an operating member which extends from an actuating means located below the lower fastening device to the upper fastening device, the actuating means, the operating means and the upper fastening device are functionally interconnected so that the upper fastening device is at least transferable from an open, radiator releasing position to a radiator holding locking position under the influence of the actuating means.

This construction gains the great advantage that the fastening device according to the invention can be mounted in a radiator without its upper fastening device having to be accessed during mounting. This makes it possible to simply stick the fastening device through the packaging at the lower edge of the radiator and up between the two vertical surfaces or sub-radiators, which are included in the radiator, in order to then easily fasten the radiator and fastening device together by actuating the actuating means.

Additional advantages are obtained if the object of the invention is also given one or more of the features according to claims 2 - 14.

COMPILATION OF DRAWING FIGURES The invention will now be described in more detail with reference to the accompanying drawings. In these: Figs. 1-4 show the invention in different setting positions for cooperation with different dimensioned radiators mounted in different height positions, Fig. 5 from above and partly in section alternative placement possibilities for the invention in a double radiator, Fig. 6 a vertical view of a post included in the object of the invention, Fig. 7 the post according to Fig. 5 seen in the direction of the arrow A in Fig. 5, Fig. 8 a control member included in the object of the invention, Fig. 9 the post according to Fig. 5 seen straight from above, Fig. 10 a part of the object shown on a larger scale approximately according to the arrow B in Fig. 1, Fig. 11 in a view corresponding to Fig. 5 a first alternative for the use of the invention in a single radiator, and Fig. 12 in a view corresponding to Fig. 11 a second alternative for the use of the invention in a single radiator.

PREFERRED EMBODIMENT Fig. 1 shows the object of the invention mounted in a double radiator, which is seen from one short end. The mounting corresponds to alternative A in Fig. 5. The radiator has a first and a second sub-radiator 1 and 2, respectively, each of which has an upper, substantially horizontal water channel 3 and a lower, substantially horizontal water channel 4. Between the upper and lower water channels 3 and 2, respectively. 4 extends radiator panels 5 with mainly vertical water channels 6. The pitch between the vertical water channels 6 may vary, but fairly standard divisions are 25, 33 and 40 mm.

On the insides of the radiator panels 5 these are provided with convector plates 7. The convector plates are vertical and are distributed along the length of the radiator. Location, design and dimensioning can vary considerably between different radiator manufacturers.

The fastening device according to the invention comprises a post 8, which extends upwards from the base, preferably perpendicular thereto. The upright 8 has at its lower end a foot plate 9 by means of which the object of the invention is attachable to the substrate. Preferably, the upright 8 and the foot plate 9 are made in one piece with each other by pressing and joining two plate details. In order to increase the strength of the upright 8 and the foot plate 9, these embossments 10 have such that the foot plate 9 has an outer edge portion, which abuts against the base and a slightly raised inner portion located inside the embossing. Correspondingly, the upright has 8 edge portions 11 where the sheet material in the two parts, of which the stand is composed, abuts closely together while the sheet material has a distance along the other parts of the upright. As a result, the stand will become hollow and have a longitudinal, in the position of use vertical inner space 12 (Figs. 7 and 9). upper fastening device 13 for co-operation with the radiator. At a lower area at some distance above the foot plate 9, the upright 8 has a lower fastening device 14, which is designed for co-operation with the lower edge portion of the radiator.

The lower fastening device 14 is further adjustable in the width direction so that the object of the invention can thereby be adjusted depending on the distance between the two sub-radiators 1 and 2. The lower fastening device 14 has laterally projecting support arms 15 and 16, which are transverse but preferably perpendicular to the longitudinal direction of the stand 8. The support arms 15 and 16 have raised directed recesses 17 and 18, respectively, for receiving the lower edge portions of the sub-radiators 1 and 2.

In addition to the adjustability in the width direction, the lower fastening device 14 is also adjustable in height along the post 8 so that the fastening device can thereby be placed both in the position according to Fig. 1 and in the position according to Fig. 2.

The upper fastening device 13 comprises two clamping members or clamping arms 19 pivotally mounted laterally in the upright 8, which are preferably pivotable in opposite directions from the upright É for position-fixing pressing from between two substantially vertically spaced surfaces. on the sub-radiators 1 and 2, for example their vertical channels 6 or the band-shaped portions therebetween in the radiator panels 5. The clamping arms 19 are arranged inside between the two plate parts, of which the upright 8 is assembled and are therefore placed in the inner receiving space 12 of the upright.

The clamping arms 19 are pivotable about shafts 20 which are transverse, preferably perpendicular to the post 8 and which extend in the longitudinal direction of the two upper channels 3 of the radiator. In particular from Figs. 2, 3 and 5 it appears that the clamping arms 19 are very difficult to reach when the object of the invention is mounted in a radiator. In order to be able to transfer the upper fastening device 13 from an open position, where the radiator is free and where the clamping arms 19 are swung towards each other, possibly completely inside the contour of the post 8, to a locking position where the clamping arms 19 are, despite the small space inside between the sub-radiators 1 and 2 expanded to press against the vertical surfaces, the object of the invention has an operating means 21 for the upper fastening device 13. The operating means 21 cooperates with an actuating means 22, which is located below the lower fastening device 14 and which is thereby easily accessible despite the radiator. The arrangement is such that the upper fastening device 13, the operating means 21 and the actuating means 22 are functionally interconnected in such a way that the upper fastening device 13 is maneuverable via the operating means between the open position and the locking position and possibly vice versa by actuating the actuating means 22.

As mentioned above, the upright 8 has a longitudinal, internal receiving space 12. In this receiving space, the operating member 21 is placed and designed as an elongate, belt-shaped body (Fig. 8). The actuator 21 is slidable in its longitudinal direction (up and down) in the receiving space 12 and has at its upper end an actuating surface 23, which abuts against cam or ramp surfaces 24 on the lower or against each other facing sides of the clamping arms 19.

The actuator 21 has at its upper end an elongate, elongate heel 25 through which it extends a connecting part 26 such as a welding point, a rivet or the like between the bath parts, of which the upright 8 is composed. Fig. 1 shows that the operating member 21 is pushed to its upper end position, which is indicated by the connecting part 26 being located at the lower end of the hole 25. In this position, the two clamping arms 19 are maximally pivoted laterally away from each other.

In Fig. 3, the operating member 21 is approximately in the middle position and it can be seen that the clamping arms 19 here have been pivoted in a significant direction towards each other. In the position according to Fig. 3, therefore, the object of the invention is set for cooperation with a relatively narrow radiator.

If the actuator 21 is moved further in the downward direction compared to the position according to Fig. 3, the clamping arms 19 will pivot towards each other further, possibly completely inside the contour of the post 8, so that in this position the clamping arms can easily pass the lower channels 4 of the radiator.

In Figs. 1-4 and 5, alternative A, the upright 8 is shown in a position so that the clamping arms 19 are expanded towards the band-shaped and vertical portions of the sub-radiators 1 and 2, the alternatives of which can be freely selected depending on the desired mounting positions for stands 8.

The actuator 21 has a further slit-shaped, elongate and longitudinal opening 27 with a widened portion 28 at the lower end. Along one edge of the widened portion 28 there is arranged a row of teeth 29 (Fig. 8) in which engage the actuating member 22, which is designed as a gear. By rotating the gear 22 it is thus possible to displace the actuator 21 in its longitudinal direction so that it moves up and down. The gear 22 has hub parts which are received in bores 30 so that the gear is position-fixed but rotatable in the post 8. The gear has an engaging device, such as an internal hexagon, for co-operation with a turning tool. The lower fastening device 14 has a reading device which, in the read condition, fixes the position of the two support arms 15 and 16 in the set position, so that the width adjustment made is thereby secured. The locking device is further designed in such a way that it reads the lower fastening device 14 in the selected setting position in height along the post 8. Finally, the locking device is also designed in such a way that in its read position it also reads the upper adjusting device 13. This is done by reading the actuator 21.

The reading device comprises a screw 33, which extends through the lower fastening device, through longitudinal openings 31 in the upright and through the longitudinal opening 27 of the actuator 21 to cooperate with a nut 32 (Fig. 10) on the opposite side of the upright 8. By pressing the screw 33 against each other the two parts, of which the upright 8 is made and the operating member 211 is located between these, the operating member 21 can be clamped internally in the upright.

The lower fastening device 13 comprises a substantially U-shaped rail 34 (Fig. 10) which abuts against one side of the upright 8. The U-shaped rail 34 has its longitudinal direction transverse to the post and is approximately horizontal.

The U-shaped rail 34 has on each side of the post a guide lug 35 whereby the guide lugs and the rail 34 delimit the post in order to be able to be moved up and down in its longitudinal direction. Between the legs of the rail 34, the two support arms 15 and 16 are arranged so that they can be displaced between the legs across the post. The support arms have longitudinal openings 36, through which the screw 33 extends, whereby, when tightening the screw, the support arms 15 and 16 are pressed against each other and against the rail 34.

As shown in Fig. 6, the elongate opening 31 of the upright has projecting teeth 37 along its opposite edges. The teeth 37 are arranged with even pitch and offset 1/2 pitch in height at opposite sides. The nut 32 has a portion extending into the opening 31 and this portion has recesses corresponding to the teeth 37 so that the nut 32 can thereby be placed in a large number of alternative height positions along the post 8.

By using the teeth 37 and the corresponding recesses on the nut 32, it is possible to place the lower fastening device 14 in a predetermined position in height without the screw 33 having to be tightened for this purpose.

ALTERNATIVE EMBODIMENT In the figures, both the impact surface 23 and the cam or ramp surfaces 24 have been shown as softly arched, it is possible for the cam to have teeth or notches in which corresponding projections or corners have smooth surfaces. According to the inventive or ramp surfaces are grooved, the actuator 21 can engage so that the clamping arms 19 are thereby prevented from pivoting through. as soon as the actuator 21 was released to be displaceable under the influence of the spring force. composed of two elongate, embossed plates which between them form a receiving space 12 for the actuator 21.

As an alternative, the upright may have another profile, such as a U-profile, in which the actuator is slidable up and down.

The operating member in such an embodiment can be made with a rectangular, square or round cross-section and only needs to have a design at its upper end which is suitable for co-operation with the clamping arms 19.

As an alternative to the degree of gear 29 of the clamping member 21 and the gear wheel 22, a threaded pin can be used on the actuator and a nut arranged on the pin, which is accommodated in a corresponding opening 1 in the post 8 so that the nut can be rotated 502 940 ll around the pin simultaneously as it is position-fixed in height in the recess of the upright.

Fig. 11 schematically shows an embodiment where the invention is applied to a single radiator. In this embodiment the two constitute substantially vertical surfaces, against which the clamping arms 19 abut partly of the vertical strip-shaped portion 5 of the radiator between its vertical channels 6, and partly of the bottom surface 38 of a U- or V-shaped portion 39 of the radiator convector plate. The post 8 is thus located inside the convector plate 7.

In Fig. 12, the upright 8 is arranged between two adjacent U- or V-shaped portions 39 of the convector plate 7, so that the clamping arms 19 abut against the radiator water channel 6 and against an abutment part 40, which is connected to the bottom surfaces 38 by means of screws 41 or by welding. on the U- or V-shaped portions 39 of the convector plate 7. Also in the alternatives with double or multiple radiators, the invention can be applied analogously to what applies according to Figs. 11 and 12.

The invention may be further modified within the scope of the appended claims.
