Description

The present invention relates to a device for fixing relative to the ground of a radiator, in particular a radiator with planar elements, joined together, generally by fins.

We know that it is not enough to place a radiator on the ground for it to be perfectly stabilized; there may be a significant risk of swaying and it is therefore necessary to fix it also relative to the wall on which it is located; various fastening devices are available for this purpose, which supplement the relative stability due to the radiator rear and flow pipes.

For radiators made up of generally lighter flat elements, it is often sufficient to fix and stabilize them relative to the wall.

To stabilize the position of the radiator, various devices have been provided in two interlocking or moving parts relative to each other and one of which is fixed to the wall and the other taking up on the radiator, the two parts being secured for example by a screw after assembly.

However, in light constructions, prefabricated panels, concrete slabs or even in partitions - small thicknesses - horizontal fixing and stabilization with respect to walls of this type are impossible. It is also impossible to provide horizontal stabilization as soon as the radiator exceeds the bottom of a window, even though currently radiators are often installed parallel to windows.

The present invention overcomes these drawbacks by proposing a device for fixing and stabilizing with respect to the floor of a radiator, in particular with planar elements integral with each other, this device consisting of four parts: a first upper part intended to rest on the upper part of a radiator element, and provided with a passage opening for the second intermediate part, a long straight screw or bolt whose length is at least equal to the height of one of the elements of the radiator to be fixed, threaded at its lower end, and provided at its upper end either with a bolt head or with a threaded end and a nut, resting on the top of the first upper part bringing the latter up as far as possible the bottom, a third lower part consisting of an anchoring means in the ground, comprising a portion provided with a threaded hole in which engages the threaded lower end of the screw or bolt, a fourth part e constituting one or more feet on which are placed the elements of the radiator, characterized in that the first upper part consists of a strip of generally angular shape with four sides, hollow cubic or rectangular, one of which vertical wall is raised and folded so as to form a hook so as to be able to take on the ridge of a radiating element, and whose horizontal upper wall is provided with said passage opening and in that the fourth part is not linked directly to none of the other three parts, but is arranged between the radiator and the floor, so that the screwing of the second intermediate part in the third lower part allows to enclose the radiator and the fourth part on which the radiator is placed between the floor and the first upper room.

Systems for fixing directly to the floor of a radiator have already been proposed, in particular in documents DE-U-1 664707 and DE-A-2 308 199. In document DE-U-2 308 199 it is disclosed a fastening system in which the foot is anchored in the ground and receives a threaded rod similar to that of the present invention. In document DE-U-1 664 707 the threaded rod is engaged in a part inserted into the ground and the function of the foot is fulfilled by the lower part which is integral with the threaded rod. In both cases, stability is ensured by an integral assembly acting as a support and attachment. These systems are not very flexible and the ground anchors must be extremely strong and be able to withstand the weight of the radiator and lateral stresses, which is a disadvantage. The present invention consists in separating the support and fixing functions by screws in a part anchored in the ground.

Preferably, the means for hooking to the ground is of the split tubular type and of constant thickness over its entire length but of variable diameter over its length having at its entering part boss lines forced outwards by an expansion piece. introduced after the fitting of the tube, and at its outer part of appreciably larger diameter, two horizontal partial cuts, one on the side of the generally larger slot, and the other diametrically opposite, and which serve for placement of a plate provided with a threaded hole which will act as a nut for the screw or bolt.

Also preferably, feet are provided in two adjustable and adjustable parts and designed so as to allow the radiator element, on which the hook of the first part is supported, to rest at two points on the foot; it is preferably between the walls of the base that the attachment device is preferably placed on the ground so as to exert a perfectly centered and perpendicular force from the ridge of the radiator on the base thereof.

In order to better understand the invention, it is now described by way of example and without limitation in relation to a drawing which represents:

• in Figure 1, a partial front view of a radiator provided with the device - object of the invention - the normally hidden parts of this device being shown in broken lines;
• in Figure 2, a cross-sectional and vertical view in a radiator at the device object of the invention;
• in FIG. 3, a perspective view in the upper part of the device;
• in Figure 4, a view of the intermediate part of the device;
• in Figure 5, a view of the lower part of the device.

Illustrated in these figures, a radiator with three planar elements 1, however a lower or higher number of elements is sometimes provided and the device object of the invention can be used whatever this number; preferably it will be placed towards the longitudinal center of the radiator.

Generally two devices are also provided along the length of a radiator, but a greater number can be provided in the case of great length. Any logical combination can be considered.

In Figure 3 there is illustrated the upper part 2 of the device of generally rectangular and hollow shape, a wall 3 is raised and folded so as to form a hook 3a which can take on the ridge 1a of an element 1 of the radiator. The shape of this hook 3a is adapted to the general shape of the radiator ridge which is tapered in the case of planar elements but sometimes rounded in other cases.

The horizontal wall 4 of the upper part 2 is provided with an opening 5; one can provide an upper part 2 provided with both an upper horizontal wall but also lower; in this case each of these walls will be provided with an opening 5, of course perfectly aligned with respect to the vertical on the ground.

In Figure 4 there is illustrated the intermediate part 6, a screw or long bolt comprising on one side a head 6a and on the other, over a certain length, a threaded part 6b.

As illustrated in FIGS. 1 and 2, the first upper part 2 being in place, that is to say the hook 3a taking on the ridge 1 a of a radiator element, the screw or bolt 6 is slid into the opening 5, the head 6a coming to bear against the horizontal wall 4 of the part 2.

In Figure 5 there is illustrated the lower part split over its entire length, or attachment means 8 in the ground which has an incoming portion 8a which will be forced outwardly the bosses 9 by the introduction of a part additional expansion 10 and this in order to ensure a certain inking of the part 8. The external part 8b of larger diameter than the incoming part, comprises two cutouts 10a, 10b, partial horizontal, that is to say perpendicular to the general axis of the third part and a generally larger cutout 10a of which is on the side of the slot 11 of the attachment means or third part 8, and the other 10b diametrically opposite.

It is in these cutouts 10a, 10b that a plate 12 is fitted with a threaded hole 13 which will act as a nut for the screw or bolt 6, this plate 12 being designed so as to abut on the planes cutouts 10a, 10b.

In FIGS. 1 and 2, a radiator foot 14 in two parts 14a, 14b has also been illustrated, which can partially fit together and slide one inside the other and a foot which is therefore extendable and adaptable to radiators of a different number of planar elements 1. On either side, each part 14a, 14b has opposite a long buttonhole 15 in which it is possible by means of a screw 16 to block one part relative to the other of the foot.

If the foot 14, as illustrated, is a particularly advantageous solution in combination with the device for fixing relative to the ground - object of the invention - because the latter can thus be installed perfectly centered relative to it; one can also install the device object of the invention with any other form of radiator base and for example also with radiators provided for the manufacture of feet.

It is important, in fact, that when the fixing device is put in place and in particular when the screw or bolt 6 is tightened, which tends to bring the elements 1 of the radiator down to the ground, that the latter is perfectly placed. and stable and that we obtain the desired hugging effect.

The device illustrated relates essentially to a radiator with planar elements; it is understood, however, that it can also, with a simple modification of the shape of its hook, adapt to any shape of the ridge of the radiator or of an element of the radiator.

Obviously, it is also conceivable that it is possible to adapt the upper part so that it comes to take no longer on the ridge of an element but of two parallel elements and side by side by providing for example by hand and other that it has a vertical wall raised and folded.
