Description

Technical field

The invention relates to a bracket, for example, a bracket or support for a window sill or the like for a single or multilayer panel heater, which is provided with convector lamellas comprising a foot or support for a window sill or the like in which a support tube is supported. preferably with a rectangular cross-section on which a support for a panel heater is displaceably disposed and is fixed to the support tube by means of a sleeve enclosing the support tube and an adjusting screw extending through the housing to the support tube.

BACKGROUND OF THE INVENTION

A similar support bracket is already known from WO 94/21970. The pedestal kaonzola known from this document already has many advantages that other pedestal brackets lack. In particular, this solution allows the heater to be mounted without first having to remove the heater package. This prevents the heating element from being contaminated by, for example, paint splashes or plaster residues, if craftsmen still work in the space where the heating element is to be installed. The heater casing present so far allows the mounted heater not to be protected by a foil or the like for protection against such contamination.

The disadvantage, however, is that in many cases the assembly is very difficult, in which for example three different bolts are to be tightened in order to achieve the correct mounting height of the support device on the support tube and to secure the heater with special hook elements on the support device.

SUMMARY OF THE INVENTION It is therefore an object of the invention to improve the known construction of the support bracket in order to reduce the cost of manufacturing the support tube and further simplify the assembly of the heater.

SUMMARY OF THE INVENTION

The problem is solved and the drawbacks of known brackets or support brackets of this kind are largely eliminated by a bracket, for example, a bracket or support for a window sill or the like for a single or multilayer panel heater provided with convector lamellae. a window sill or the like in which a support tube is arranged, preferably with a rectangular cross-section, on which a support for a heater is displaceably mounted and fixed to the support tube by means of a sleeve enclosing the support tube and an adjusting screw reaching therethrough according to the invention, characterized in that on one side wall of the sleeve a thread for the set screw is formed near its end and at least one adjacent to said side wall of the perpendicular side wall of the sleeve extends straight or bent, straight a strip or sash running in the direction of the casing, which can be inserted into vertical channels formed in the convector fins of the plate heater.

Instead of using hooks according to the prior art which are mounted either on the water supply pipes or on the brackets, the assembly according to the invention is carried out by inserting the strips or wings of the support brackets into the convector lamellae, with the sleeve slid over the support brackets. the tube and carrying these strips or wings are jammed during the tightening of the set screw to fix the sleeve at the desired height on the support tube due to the special arrangement of the set screw along the length of the housing, which is allowed by the play. As a result of this jamming, the said strips or wings are tilted out of alignment with the support tube and, as a result, inside the convector slats ^f, these strips or wings are 'disrupted' from the support tube.

The casing is provided with one or two wings which have a certain distance from each other and possibly from the support tube, which is adapted to the pitch or grid of mutually parallel channels of the convector lamellas. Therefore, it is usually sufficient to use one strip or wing. If, however, a particularly uniform expansion is to be achieved, or if the weight of the heating element is extremely high or the mechanical strength of the convector fins is not sufficiently high, it may be advantageous if more than one wing is used, i.e. two wings between which the support tube passes. The wings are arranged at such a distance from each other and from the support tube that they can be inserted into two adjacent convector fin channels and, when the adjusting screw is tightened, are adjacent to the inside of the convector fins so that the support tube is pressed against the plate heater. from which these convector lamellas protrude.

Of course, other pitches or raster may also be used so that the wings can then be inserted into channels other than the closest to the convector fins.

Preferably, the weight of the heating element is transmitted or retained so that bends are formed on the wings which form the abutment surfaces for the lower edge of the convector lamella.

In view of the noise insulation, or possibly to prevent the occurrence of scrap during the thermal expansion of the heating element, a plastic insert can be used as a silencer in the area of the bend. The metal convector lamella of the plate heater then does not abut directly on the metal in the region of said deflection, because there is a plastic insert between the convector lamella and the deflection.

^ ^ - ··

As is known in the art, the upper end of the support tube may be closed by a plug having a laterally extending head or edge. In this way, a precise adjustment and positioning of the type of heater to the cross-section of the support tube can be achieved. In addition, if the plug is made of plastic, an additional noise insulation is achieved again.

It is preferred that the laterally projecting plug head is sized so that it can be pushed into the convector fin channel to accommodate the support tube to the particular dimensions and spacing of the convector fins.

Furthermore, it is advantageous if a further set screw is provided on the side of the sleeve profile opposite to the first thread near the lower end of the sleeve, thereby achieving a high reliability of the fixing of the sleeve on the support tube and also adjusting the point around tightening of the first set screw tilts. Preferably, this additional thread is formed in a projection extending into the interior of the housing.

In addition, it is advantageous if a hole is provided near the free end of the band or wing, in which a gripping protrusion extends from the arm of the L-shaped adapter adapters with its second arm around the narrow edge of the band or wing and this edge of the sash and the plate heater. This adapter also contributes to the versatility of the base bracket according to the invention and, when made of plastic, which is advantageous, also contributes to the damping of the transmission of noise.

From the point of view of the reliability of the fixing of the sleeve on the support tube, it is furthermore advantageous if the set screw is provided with a cutting ring which on the face of the set screw t

cuts the side tube into the side wall material.

The aforementioned wing may be welded to the side wall of the housing. However, it is also possible that the sash is riveted, pinned or screwed to the side wall of the housing.

It is further preferred that the sash is attached to the housing the pivot and the pivot angle between the sash and the sleeve is adjustable, i.e. it can be increased by, for example, a screw, for example a compression screw or the like.

The holder or support bracket according to the invention is particularly suitable for a particular heater structure in which water

WITH*. The plate-shaped heating element to be flowed on one side of the plate extends vertically extending slats with a rectangular profile which g. have mutually spaced apart.to each other such that it is possible to mount the support tube in at least one orientation between these

- lamellas. Such heating elements are installed such that the lamellae ig. the provided side of the plate heater faces the wall.

and·. -3 * '

Such a heater, which consists of a plate on one side of which the convector lamellae are arranged, is referred to as the type 11 heater. If a convector lamellae which emanate from one plate are arranged on another convector lamella, it is a heater. Type 21, which can also be installed with the support or support bracket of the invention.

Furthermore, there is a heater type 22, which consists of two plates and two rows of convector lamellas based on these

·. boards. Type 33 heaters may also be mounted on the support brackets according to the invention, consisting of three plates and three rows of convector lamellas extending therefrom.

On the other hand, a heating element of the type 10, which consists of only one plate without convector plates arranged on it, cannot be mounted on the base bracket according to the invention. For this type 10, a support bracket as described in the prior art is suitable.

On the other hand, for the radiators of type 11, .. 21, 22 etc., the support bracket according to the invention is considerably more advantageous because of its extremely simple construction and the possibility of mounting, since in this way both height adjustment and connection between support device and support tube are possible. and the connection between the support device and the heater is achieved by means of a single set screw. Similar to the prior art support brackets, it is also possible here to mount the heater in a packed condition.

Due to the use of a plug in the upper end of the support tube, it is possible to suffice for all construction heights of heating elements with a single design length of the support tube, since the direction of the upper part of the heating element is achieved by the plug being tightly clamped between convector slats. The length of the wing determines the angle of its deflection when the set screw is tightened. It is expedient if the length of the leaf is aligned with the contact force of the set screw, which means that the greater the contact force of the set screw can also be the longer the length of the band or the wing. On the other hand, at a high contact force of the adjusting screw, a smaller deflection in the region of the adjusting screw is sufficient, since this results in greater deflection at the end of the longer wing due to the larger lever. This way it is possible to capture different dimensions and spacing of convector lamellas from different ones. manufacturers.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1, a support bracket 10 is provided, which is provided with a foot 24, which consists of a support plate 26, which can be screwed to the floor by means of openings (not shown). A tubular extension 28 extends from the upper side of the base plate 26 and is welded to the base plate 26, for example. A support tube 32 can be inserted into the tubular extension 28 or, alternatively, the support tube 32 can be pushed onto the tubular extension 28. This support tube 32 has a rectangular cross-section, like the pipe extension 28. However, other prismatic cross-sections that exclude rotation can also be envisaged. Less favorable, but also applicable, would be a circular cross-section.

The support tube 32 carries a washer or support 34, which is again shown in more detail in FIG. 2C itself. Similarly, the support tube 32 can support the support device 134 of FIG. 4. The support device 34 consists of a housing 35 that surrounds the support tube 32 with little play so that the housing 35 can slide up and down the support tube 32. Preferably, on one of the narrower sides of the rectangular cross-section of the sleeve 35, a thread 37 for the set screw 36 is provided at or near its upper edge, which thread 37 may be formed in the material of the slot 35 or formed by a welded nut or the like. The weld nut provides greater stability when the clamping force is transferred from the set screw 36 to the sleeve 35. The side of the sleeve 35 provided with the set screw 36 has some clearance 28 relative to the support tube 32 so that the sleeve 35 can tighten against the support tube 32 of the set screw 36 to perform a tilting movement to a limited extent.

This tilting movement is transmitted from the housing 35 to the strap or wing 44 that is attached to the housing 35. This movement is indicated by the arrow 42. The wing 44 is between its mounting area 46 on the housing 35 and the free portion 50 which is spaced apart from the wide side 48 of the support tube 32, provided with a bend 52, which forms an abutment surface 54 with its inner side and at the same time leads to an increase in the distance 56 between the wide side 48 of the support tube 32 and the wide side 48 facing the free portion 50 of the wing 44.

FIG. 3 is a perspective view of a plate heater 62 which comprises two spaced apart plates 64, 66, preferably steel sheets, which are circumferentially watertightly connected to each other by a bend and a welding seam 58. wherein only the lower welding seam 58 is shown, while the other edges or edges are shown in the cut-out.

On the outer surface of the plate 64, vertically oriented lamella sheets are welded, which only form the open and upwardly open air channels 68 with a substantially rectangular cross section, and at the same time the laterally open channels 70 between these air channels 68. The air ducts 68 and the laterally open ducts 70 have a substantially identical, substantially rectangular cross-section of width 72 and depth 74. The support bracket 10 shown in FIG. 3 associated with the plate heater 62 is inserted into the support tube 32 into a of the laterally open channel 70, which means that the width 172 of the support tube 32 must be chosen to fit within the inner width of the laterally open channel 70. At the same time, it is apparent that the free portion t50 of the leaf 44 is inserted into the air channel 68 in the convector fins so that the lower front edge of one of the walls of this air duct 68 abuts against the abutment surface 54 of the wing 44, which is formed by the deflection 52. Insertion of the support bracket 10 shown in FIG. 1 to achieve the condition shown in FIG. 3, thus requiring the opening of the heater package 62 only to its lower edge 1 to access the lower opening. 1, then the support bracket 10 of FIG. 1 can be inserted through its support tube 32 into a laterally open channel 70, or into a corresponding other laterally open channel, and at the same time the upper end of the free portion 50 of the wing 44 into an adjacent air channel 68.

Now, a set screw 36, not shown in FIG. 3, can be screwed into or tightened in the thread 37. Before that, however, the correct position of the sleeve 35 on the support tube 32 and hence the height of the plate heater 62 above the floor is set. By this tightening or clamping, the housing 35 and thus also the upper end of the free portion 50 of the sash 44 swivel in the direction of arrow 42, i.e. from the plate heater plate 62 towards the wall 76 of the lamella channel. At the same time, the channel wall 78 of the laterally opened channel 70 is pressed against the base tube 32 towards the narrow side 140 of the base tube 32, so that the respective components of the upper end of the base bracket 10 are wedged into the convector fins 60. The heater 62 is fixed to the support bracket 10 in its axial direction.

The torque exerted on the one hand on the base bracket 10 and on the other side on the plate heater 62 is retained by the base bracket 10 by its attachment to the floor and by the plate heater 62 not shown here on the other or the other console .10, so this torque is not distracting.

If this torque action was to be undesirable for some reason, a second wing 144 may be used as shown in FIG. 4, so that the wings 44, 144 can be inserted into two, preferably adjacent air channels 48, 8. 168, while the support tube 32, not shown in FIG. it is again introduced into the intermediate laterally open channel 70. If the set screw 36, not shown in FIG. 4, is now tightened, the two wings 44, 144 move in the same direction indicated by the arrow 42 in FIG. 1, but due to the symmetrical arrangement of the two wings 44. 144 torque canceled.

It has proven to be advantageous to insert a plastic insert 78, which is normally abutted on the support surface 54, to be suppressed by the thermal dilatation and also to prevent sound transmission between the abutment surface 54 formed by the deflection 52. 2D. This plastic insert 78 has an angular shape according to FIG. 2D, but could also have a different shape. The plastic liner 78 could be fixed by gluing by wrapping the wing 44 in the manner of letter C or, as shown, that the plastic liner 78 is provided with an outwardly extending pin 80. which can be inserted into the corresponding bore or bore 82 in the wing 44 and locked in this way.

Figure 2E is a perspective view of plastic

The stopper 84, which can be inserted by its press-fit part 86 into the internal cross-section 88, see FIG. 2B · * support pipes. The head extends beyond the heel portion 86, the cross-section of the head 90 preferably corresponding to or extending beyond the outer cross-section of the support tube 32, for example to provide a clamp connection within the laterally open channel 70 of the convector fins 60. The laterally open channel 70 should be substantially larger than the outer cross-section of the support tube 32. Thus, by simply replacing the plug 84, adaptation to different shapes of convector fins 60 of the plate heater 62 could be achieved.

The distance 56 of FIG. 1 should be selected so that the wing

1¾. 44 came approximately in the middle of the respective air duct 68.

wherein the two wings 44, 144 are correspondingly arranged in two adjacent air channels 68, 168.

The swiveling movement in the direction of the arrow 42 in FIG. 1 is usually due to the tightening of the set screw 36 simply without the need for further measures simply because the set screw 36 is located at the upper end of the sleeve 35. If this swivel movement is not sufficient, the same could be achieved by reducing the cross-section at the lower end of the sleeve 35.

Mounting with the illustrated support bracket 10 is also possible in the case of plate heaters which consist of a pair of the illustrated heater 62 which are adjacent to each other by their convector lamellas 60, so that the resulting assembly has flat, smooth surfaces on both sides.

By virtue of the fact that the plastic plug 84 can be designed to abut against the walls of the laterally opened channel 70, the length of the support tube 32 need not be so long that the support tube 32 extends through the entire plate heater 62. The support bracket 10 of a single construction length is sufficient to assemble plate heaters 62 of different heights.

It is expedient if an annular cutting blade is used as the set screw 36, which is firmly cut into the material of the narrower side wall 40 of the support tube 32, thus ensuring a reliable grip.

FIGS. 5A and 6A show, in a similar view to FIG. 1, two embodiments in which the wings 144 and 244 extend directly, i.e., not bent as in FIG. 1. The wings 144, 244 are welded to the housings 135, 235; slightly sloping, i.e. at an angle 14 2, and out of alignment with the longitudinal axis of the support tube 32. When the plate heater 62 is pushed, these wings 144, 244 are substantially aligned with the support tube 32 and the housing 135 and 235 respectively. will rise. If the upper set screw 236 in FIG. 6A is now tightened, the axle 45 of the sleeve 235 is again partially pushed toward the axis of the support tube 32, causing the wings 144 to return to the deflected position shown in FIG. 5A. and 6A, respectively, and grip the plate heater 62 (not shown) as described above.

Second, the lower set screw 336 further increases the holding force when it is tightened, by which the sleeves 135, 235 are attached to the support tube 32 and the wings 144, 244 to the plate heater 62 (not shown).

Due to the play of the bushings 135, 235 in the direction of the narrower side wall 40. of the support tube 32, sufficient space can be created for the wall thickness of the convector lamella 60 between the support tube 32 and the wings 144,244. 135. 235.

The upper front edge 47 of the housing 135 in Fig. 5A serves as a bearing surface for the plate heater 62. In Fig. 6A a separate extension or flange 147 is used.

In FIGS. 5B and 6B, plugs 184 'are shown on which abutment strips 185 are slidably mounted, which can be used to position the support tube 32 within the clear cross-section of the air duct -68.

FIG. 7, which on a slightly enlarged scale illustrates a similar base bracket 10 to FIGS. 5 and 6, also illustrates this plug 184 in some detail and shows that it consists of a U-member 186. whose connecting web 193 carries a seating rail 185 and whose ends 187, 188 form at their ends a wedge-shaped space in which a wedge 189 is disposed, which rests these legs 187, 188 apart from each other when only the indicated screw 190 is pulled by which the wedge 189 is drawn between the legs 187 188. Thus, wedging of the plug 184 at the end of the support tube 32 is achieved. The screw 190 can be screwed into a thread in the wedge 189, which can be cut in this wedge 189, preferably of plastic. Another solution may be a metal nut that is inserted into the slot 191. The screw 190 may simultaneously pass through the elongated slot 192 in the seating strip 185 and hold the seating strip 185 with its head slidingly on the connecting bridge 193.

FIG. 7 shows a base bracket 10 in which a further thread 443 for a further set screw 441 is provided at the lower end of the sleeve 435 on the side profile of the sleeve 435 opposite the first thread 437. The thread 443 is preferably formed in a thickened wall of the sleeve 435. which protrudes inwardly of the housing 435. The reinforcement with the thread 443 extends and the set screw 441 therein serves to create a defined center of rotation when the sleeve 435 is pivoted and thus also the strips or wings 444 relative to the support tube 32 when the first screw 436 is tightened in the first thread 437.

A further advantage of this embodiment is that an additional set screw 441 can be used to pre-adjust the housing 435. in which the other set screw 441 is tightened.

14 so as to engage and grip the support tube 32 before the first adjusting screw 436 is tightened to thereby effect a swivel movement of the strips or wings 444 relative to the axis of the support tube 32, thereby securing the plate heater 62 into which or into whose channels 68, 70 the support tube 32 with strips or wings 444 is inserted. This plate heater 62 will be retained by spreading the narrow side 55 of the support tube 32 from the opposing edges 57 of the strips or wings 444.

In terms of easier adaptation to a significantly different internal. , the dimensions of the convector fins 60 of the plate heater 62 may be advantageous if a recess or aperture 45 is formed near the free end of the band or sash 444 to receive a gripping projection 47 that extends from one arm 50 of the adapter 49, which This adaptation adapter 49, with its second arm 53, surrounds the narrow edge 57 of the strip or sash 444. which serves to hold the panel heater 62 described. Thus, when the sash 444 is deflected, it comes between the narrow edge 57 of the band. or wings 444 and the inside of the convector fins 60. Thus, the thickness of the second leg 53 of the adapter 49 can accommodate the various dimensions of the plate heater 62 that may be considered. The removable design of the adapter adapter 49 allows it to be easily replaced, so that the support bracket 10 can be used without great modification for plate heaters 62 with different dimensions.

Here, the plastic insert 178 is in the form of a ring which surrounds the support tube 32 and is provided with protruding abutment projections 193,. which aligns the wings 444 with the upwardly displaced plastic liner 178 relative to the axis of the support tube 32, thereby allowing the heater 62 to slide onto the support bracket 10 without obstructing the deflected wings 444 too far. 62 onto the base bracket 10 compresses the plate heater 62 into the position shown in FIG. 7 in which the plastic insert 178 is already moving the wings 444 in the deflection direction, i.e., in the direction of the arrow 194 in FIG. does not prevent. ..

If the support bracket is turned over and inserted into the convector fins 60 of the plate heater 162 in Fig. 9 by the support tube 132 from above, the foot 24 being replaced, for example, with window sills 124 or the like, the embodiment of Fig. 9 is achieved. The support tubes 132 relative to the wings 344, which can be supported by the edge 247 or by the bend 152, for example on the edge of the convector fins 60 and are therefore at a certain height, can be adjusted to the desired height of the window sill 92. By tightening the set screws 336 or 441 and 436, the support rod 132, 32 is fixed to the wings 344 or 444 as well as the support pipes 132, 32 and the wings 344, 444 to the convector fins 60 of the plate heater 162 and thus window sill height adjustment 92.

The panel heater 162 may be mounted on the floor in the manner described above, and other channels 68, 78 of the panel heater 162 may also be used for the base brackets 10 and the window sills 132 for the window sills 92, and especially for the long base tubes 32. The panel heater 162 can also be mounted to the floor in a completely different manner.

The window sill support 124 may be attached to the support tube 132 by, for example, a clamp connection, such as the foot 24 in Fig. 3, or may be welded to the support tube 132 as indicated in Fig. 9. it is preferably adapted to the width of the window sill 92.
