Radiator mounting bracket

The present invention relates to a holding device, in particular for panel radiators, with a stationary wall bracket which has an upper end and a lower end and a clamping bracket which is movable relative to the wall bracket and has an upper holder, which is held at the upper end of the wall bracket by a connecting element in its guide region so as to be displaceable in the direction of the longitudinal axis of the wall bracket and with a force element which acts between the clamping bracket and the connecting element.

Generic holding devices are used for the quick installation of radiators, for example panel radiators. During installation, the holding device is first partially attached to a wall, usually by attaching the wall bracket in a vertical orientation. After a lower edge of a radiator has snapped into place in an area of the wall bracket that is already firmly attached to the wall, the radiator is held from below by resting in a guide. However, the radiator can tip out of the wall bracket by pivoting around an axis that runs in the lower guide.

Various clamping brackets are known for completely fastening a radiator to the wall bracket. These are fastened to the upper end of the wall bracket in such a way that they can be fixed in a position that they can grip the upper area of the radiator with a recess. In particular, it is known to fasten a clamping bracket in the upper area of the wall bracket by means of screw connections on the wall bracket in such a way that the clamping bracket can be fixed in a suitable holding position. Known holding devices have fastening devices that can fix the clamping bracket in a variable position in the direction of the longitudinal axis of the wall bracket, as well as clamping devices that set the distance of the holding area of the clamping bracket, which is positioned in direct contact with a radiator, at a variable distance perpendicular to the axis of the wall bracket.

:&Pgr;

The disadvantage of the known devices for holding radiators is that the clamp, which is movable relative to the wall bracket, has to be attached to the wall bracket in several steps in order to ensure that the radiator is securely held.
5

The present invention therefore has the object of providing a holding device which enables a simplified assembly of the radiator, so that a clamping bracket which can be moved relative to the wall bracket is easily attached to the wall bracket and, moreover, enables a quick and easy assembly of the radiator in the holding device.

According to the invention, in order to achieve the object, the clamping bracket has a locking device which can hold it in a position remote from the lower end of the wall bracket against the action of the force element and holds it in a position closer to the lower end of the wall bracket under the action of the force element, wherein the change between these two positions can be achieved by pivoting the guide area relative to the wall bracket.

A flat element, such as a panel radiator, is held at the lower end of the wall bracket in a lower guide and at the opposite end of the wall bracket by an upper bracket, the U-shaped area of which encloses an upper end of the flat radiator. The lower guide is fixed in its position to the wall bracket, while the upper guide is part of the clamping bracket, which can be moved in the direction of the longitudinal axis of the wall bracket in order to adjust the distance between the guide and the upper bracket to the dimension of the flat radiator to be enclosed.

According to the invention, the clamping bracket is connected to the wall bracket in such a way that it can be moved in the longitudinal direction of the wall bracket and is moved towards the lower end of the wall bracket by the action of force, for example spring tension. The movement of the clamping bracket in the longitudinal direction of the angle profile of the wall bracket is made possible by the fact that the clamping bracket is loosely guided by the U-shaped design of the wall bracket. Furthermore, the clamping bracket is held in the recess of the angle profile of the wall bracket by a connecting element. This

can preferably be done by holding claws that can be positioned at a distance between the plate of the connecting element and the wall bracket. The connecting element is held stationary by its holding claws on the side of the wall bracket facing away from the radiator to be held and thus enables the movement of a guide area between this side of the wall bracket and the plate of the connecting element in the longitudinal direction of the wall bracket. The force acting on the clamping bracket is generated between the connecting element and the clamping bracket, for example by a spring tension between the connecting element and the guide area of the clamping bracket, so that the clamping bracket can only be removed from the lower end of the wall bracket against the force acting on it. In this way, the clamping bracket is subjected to force so that its upper guide presses an element, for example a panel radiator, against the lower guide at the lower end of the wall bracket. The connecting element can be designed either as one piece with the wall bracket or as a single component, while the clamping bracket consists of a single component according to the invention.

In a particular embodiment of the invention, it is further provided that the clamping bracket can be fixed in an upper position so that it is in a distant position from the lower guide at the lower end of the wall bracket in the direction of the longitudinal axis of the wall bracket.

The advantageous design of the clamp and wall bracket means that the clamp can be held in a position that allows the element to be held, the panel radiator, to be easily inserted into the lower guide at the lower end of the wall bracket and below the upper bracket on the clamp, without the clamp having to be held additionally, for example by hand. After the element to be held has been inserted into the intended position on the wall bracket, the clamp can then be released from its fixed position with a simple movement of the hand, for example by exerting pressure in the direction of the wall bracket, so that the application of force, for example a spring tension, moves it in the direction of the lower end of the wall bracket and the clamp rests with its upper bracket on the upper edge of the panel radiator and fixes it with its retaining lug.

The design of the holding device according to the invention therefore enables both the assembly of the element to be held, the panel radiator, between the upper and lower guides without the need to use special locking elements such as rivets or screws and also, if desired, to enable the construction of the holding device itself without special connecting elements such as rivets or screws.

A compression spring is advantageously used as the force element, which is accommodated in a receiving pocket consisting of a groove, with the edges of the groove partially equipped with elastic projections for fixing the spring. This measure makes it possible to pre-assemble the connecting element and the compression spring, and the elastic projections prevent the spring from falling out, thus simplifying the further assembly of the holding device.

In a further embodiment of the invention, it is provided that the connecting element preferably has four retaining claws that hold it at a distance from the wall bracket and the guide area for the clamping bracket is arranged between the wall bracket and the connecting element, the retaining claws being arranged in pairs opposite one another and arranged in corresponding openings in the wall bracket, into which the retaining claws can be inserted while being deformed and which, after the retaining claws have partially passed through the openings, offer an area of the retaining claws a contact surface against which the retaining claws are supported against a backward movement after their deformation has at least partially returned. The clip technology used further simplifies assembly and also enables defective components to be replaced at any time. The retaining claws can be formed integrally and elastically bendably on the base plate, the retaining claws being dimensioned so that the connecting element is guided loosely between the wall bracket and the connecting element and pivoting is possible in the upper area.

To secure the connecting element for later mounting of the panel radiator, a locking lug is also provided which protrudes from the plane of the guide area opposite to the wall bracket and can be hooked into a corresponding locking recess.

The downward movement can be caused by simply pushing the connecting element backwards. This can be done, for example, by simply putting the panel radiator in place.

In a further embodiment of the invention, it is provided that a receiving element is detachably arranged at the lower end of the wall bracket and has a lower guide plane, wherein the groove has the same distance from the longitudinal axis of the wall bracket as the upper holder of the clamping bracket and wherein the lower guide plane can consist of a bevel or a curve.

The invention is explained in more detail below with reference to the figures.

Figure 1 shows the holding device 1 in the assembled state, with a wall bracket 10 which has a substantially U-shaped profile and at a lower end a bent lower region 15 for spacing

of the lower end from the plane of the wall bracket 10. A receiving element 40, which is fitted into the bent lower region 15 of the wall bracket 10 and has a lower groove 41 at the end of the bent lower region 15, serves to receive the edge region of a panel radiator (not shown). At the opposite end of the wall bracket 10, a clamping bracket 20 is mounted, which as an upper holder 21 has an upper U-shaped region that can grip an upper edge of a panel radiator and is held by a connecting element 30 by means of pairs of opposing holding claws 36 in corresponding rectangular openings 16 on the wall bracket 10.

The openings 11 and 12 of the wall bracket 10 serve to accommodate fastening elements of the wall bracket on a surface that is to support the wall bracket 10 and the element to be accommodated. As shown in Figure 4, the wall bracket 10 has, in addition to the openings 11 and 12, bent legs 13 parallel to the longitudinal axis of the wall bracket 10, which in turn are connected to support surfaces 14, also parallel to the longitudinal axis of the wall bracket 10.

When designing the wall bracket 10, it should be noted that the support surfaces 14 together form a surface that can come into contact with a substrate when the wall bracket 10 is attached to the base, for example a wall. For attachment to a flat surface as a substrate, for example a wall, it should therefore be noted that the support surfaces 14 together lie in a plane that can rest on the substrate. In a preferred embodiment, the legs 13 of the wall bracket 10 are aligned perpendicular to the surface formed by the two parallel legs 13, but other angles are also possible.

The wall bracket 10 further comprises openings 16, preferably rectangular, which extend parallel to the longitudinal axis of the wall bracket 10. These openings 16 serve to accommodate the retaining claws 36 of the connecting element 30 and are aligned in such a way that they accommodate the retaining claws 36 in such a way that the retaining claws 36 are supported against the surface of the wall bracket 10 in the more relaxed state after the retaining claws 36 have been introduced under tension through the openings 16. In this way, the connecting element 30 can be connected by simply passing the retaining claws 36 through.

through the openings 16 of the wall bracket 10 and hooking the retaining claws 36 behind the protruding surface of the wall bracket 10. The dimensional stability of the retaining claws 36 counteracts their bending back into a position that could enable the retaining claws 36 to be guided backwards through the openings 16.

The retaining claws 36 are designed in such a way that they can hold the connecting element 30 at such a distance from the wall bracket 10 that there is sufficient distance between the wall bracket 10 and the plate 37 (see Fig. 3) of the connecting element 30 that the guide area 24 of the clamping bracket 20 can be movably guided in this space. The guide area 24 of the clamping bracket 20 has a shape such that it lies in a plane so that a displacement in the longitudinal direction of the axis of the wall bracket 10 is possible. Furthermore, the guide area 24 of the clamping bracket 20 can have a tapered area such that it is guided between the retaining claws 36. Other shapes of the flat guide area 24 are also possible, as long as the guide area 24 can be guided displaceably between the connecting element 30 and the wall bracket 10, wherein the holding claws 36 can extend from the plate 37 of the connecting element 30 through the openings 16 of the wall bracket 10.

In addition, the clamping bracket 20 has, at its end visible in Figure 1, a U-shaped upper region as an upper holder 21, which can grip around an upper edge of an element to be accommodated, for example a panel radiator. An advantageous embodiment of this upper holder 21 has retaining lugs 22 which form a recess 23 between them, as shown in Figure 5. In this way, the retaining lugs 22 can grip around a web of the element to be accommodated, which interrupts its upper edge. At the opposite end of the clamping bracket 20 there is a contact point 26 for a force element, which is characterized by a projection from the plane of the guide region 24. In an advantageous embodiment, it is provided that the contact point 26 extends into the plane of the guide region 24, which is opposite the plane of the upper holder 21.

The contact point 26 of the clamping bracket 20 serves to attach one end of a force element 38, for example a compression spring, as shown in Figure 3

shown. The force element 38 is supported on a second contact point 35 on the connecting element 30 and exerts a force on the clamping bracket 20, which puts the latter under tension relative to the connecting element 30 in the direction of the receiving element 40 or the lower end of the wall bracket 10. In this way, the force element 38 ensures that the distance between the lower end of the wall bracket 10 or the lower groove 41 arranged there and the upper holder 21 of the clamping bracket 20 can only be increased against the tension of the force element 38. For pre-assembly of the force elements 38, a receiving pocket 18 consisting of a groove is provided, which has lateral elastic projections 19 so that the force element 38 is held.

Due to the design of the holding device according to the invention, an element which is arranged between the upper holder 21 of the clamping bracket 20 and the lower groove 41 of the receiving element 40, such as a panel radiator, is held by the tension of the force element 38 in conjunction with the approximately form-fitting adjustment of the upper holder 21 and the lower groove 41. Such a position of the holding device, but without a panel radiator, is shown in Figure 1.

For inserting the element to be held, for example a panel radiator, between the upper bracket 21 and the lower groove 41, the distance between these two guides is too small in the position in which the force element 38 brings the clamping bracket 20 into the position in which the clamping bracket 20 is positioned close to the lower end of the wall bracket 10.

In order to insert the panel radiator to be held between the bracket 21 and the groove 41, it is necessary that there is a larger distance. According to the invention, the clamping bracket 20 can be held in a position that has a larger distance between the upper bracket 21 and the lower end of the wall bracket 10, i.e. the lower groove 41. For this purpose, a locking device, for example a locking lug 25, is provided on the clamping bracket 20, which then holds the clamping bracket 20 in a position further away from the lower end of the wall bracket 10 when the locking lug 25 rests on the upper edge 15b of the wall bracket 10. Instead of an upper edge 15b of the wall bracket 10, a further recess can also be provided in the wall bracket 10, which in the same

Surface of the wall bracket 10, like a recess 15a. When the clamping bracket 20 is held with its locking lug 25 on the upper edge 15b of the wall bracket 10, the force element 38 is placed between the contact point on the connecting element 30 and the contact point 26 on the clamping bracket 20 in its tensioned state. The force element 38 thus exerts a greater force on the contact point 26 than in the position in which the clamping bracket 20 is positioned on the wall bracket 10 such that it has a shorter distance to the lower end of the wall bracket 10.

If, after setting the panel radiator to be accommodated in a lower groove 41 at the lower end of the wall bracket 10, the clamping bracket 20 with its upper holder 21 is to be brought closer towards the lower end of the wall bracket 10, a slight pressure on the panel radiator in the direction of the wall bracket 10 is sufficient to disengage the locking lug 25 and thus enable the connecting element 30 to slide down due to the effect of the force element 38, so that the upper holder 21 comes to rest on the upper edge of the panel radiator.

In order to enable the movement of the guide area 24 out of the plane of the wall bracket 10 by pivoting at least the distance that the locking lug 25 protrudes from the plane of the guide area 24, it is necessary for the holding claws 36 of the connecting element 30 to be designed in such a way that they assume a position in which they hold the connecting element 30 between the plate 37 of the connecting element 30 and the wall bracket 10 on the one hand and the distance between the wall bracket 10 and the plate 37 corresponds to at least the thickness of the guide area 24 plus the distance by which the locking lug 25 protrudes from the guide area 24 on the other hand. The pivoting movement is therefore sufficient to enable the locking lug 25 to be disengaged.

The receiving element 40, as shown in Figure 2, forms with the legs 13 of the wall bracket 10 a lateral guide for the guide area 24 of the clamping bracket 20, wherein the complete guidance of the guide area 24 in the direction of the longitudinal axis of the wall bracket 10 is ensured by the plate 37 of the connecting element 30. In a preferred embodiment, the connecting element 30, as shown in Figure 3, is equipped with lateral legs 34 for guiding the guide area 24. A

Recess 39 in the connecting element 30 serves to accommodate projections of the guide area 24, which are in the area of angles in the clamping bracket

20 serve to increase stability.

The receiving element 40 is preferably designed in such a way that it fits into the bent lower region 15 of the wall bracket 10 and ensures that the lower groove 41 is spaced apart from the plane of the wall bracket 10. To easily hold the receiving element 40, a raised nose 17 at the end of the lower region of the wall bracket 10 can engage in a recess 43 of the receiving element 40.

In a preferred embodiment, as shown in Figure 6, the receiving element 40 has a guide plane 42, which can be designed to be concave in accordance with the bend of the wall bracket 10 at the lower end, but flat or convex guide planes are also possible. The guide plane 42 serves solely to simplify the assembly of a panel radiator, in which an edge area is guided into the lower groove 41 via the guide plane 42. Since the receiving element 40 has a fixed lower groove 41 and thus a fixed distance between the lower groove 41 and the wall bracket 10, it is necessary to determine the distances between the lower groove 41 and the upper bracket.

21 to the plane of the wall bracket 10 so that an element to be fastened, for example a panel radiator, is held parallel to the substrate on which the wall bracket 10 is fixed by means of fastening elements.

In the preferred embodiment, the connecting element 30 has two pairs of opposing holding claws 36 for holding in the wall bracket 10, which are arranged one behind the other in the longitudinal direction of the axis of the connecting element 30 and protrude vertically from the plate 37, as shown in Figure 3.

The alignment and number of openings 16 in the wall bracket 10 must also be provided in accordance with the number of retaining claws 36. As explained above, the openings 16 must have suitable dimensions to be able to guide the retaining claws 36 through, so that their dimensional stability provides them with sufficient tension to be pressed against the edges of the openings 16 so that they do not come out of the wall bracket 10 again.

Wall bracket 10 can not slide out, but are held by contact surfaces on the wall bracket 10.

Metals are particularly suitable as materials for the production of the wall bracket 10 and the clamping bracket 20, and plastics are also suitable for the connecting element 30 and the receiving element 40.
