Description

The present invention relates to a holding device for a radiator with radiator tubes, the one Wall mounting with a sleeve, one in the sleeve longitudinally displaceable support element, a fixing member for Locking the support element in its longitudinal position, a first clamping part connected to the support element is, and a second clamping part for clamping two adjacent radiator tubes between this and the has the first clamping part.

As already known, a radiator essentially points a radiator body, which is covered by collectors and Radiator tubes and their holding device for the Attachment of the radiator body to a wall defined is. There are currently essentially two types of holding devices in trade, a first type of which in European patent application EP-A-0554473 has a fastening part, which in to be anchored to a brick wall, and one Clamp that is carried by the fastening part and the like an element of the radiator body between two halves a holding device. A second type of holder, that in the German utility model DE-U-8425270 and in European Patent application EP-A-0386301 also an attachment to that in the brick wall is introduced, and two clamping elements, from opposite Sides between two radiator tubes of the Radiator body are introduced, and by a in integrated one of the clamping elements mentioned above Clamping screw are connected.

The first type of fixture requires multiple clamps different geometrical designs to adapt to the geometric shape of the element of the radiator body. It is therefore state of the art a different holder for each type of radiator to train.

The second type of radiator has clamping elements that only the clamping of cylindrical Allow radiator tubes. There is an assembly kit only to a certain type of radiator with a defined one Adjusted pipe diameter and pipe spacing. The Clamping elements used here only have one Pair of support zones, depending on the size and The distance between the radiator tubes must be replaced. The assembly, in which is particularly disadvantageous it is necessary to first remove the clamping elements from the Wall side of the radiator on the radiator body and then attach the radiator from behind mounted clamping elements on the already predetermined Attach wall fastenings to the brick wall. It is extremely problematic to have the radiator on the Wall to attach, as the previously attached to the radiator Clamping elements exactly with the position of the wall fixings fixed to the wall have to. In case of discrepancies it is a simple one Readjustment is no longer possible because of the clamping elements can only be adjusted from the rear of the radiator are, i.e. the entire radiator must be off the wall again moved away and the clamping elements must be replaced by Loosen and move to another position be moved. This makes it more complex iterative process started.

The object of the present invention is therefore a more universal compared to the prior art mountable and variable on different types of radiators to create adjustable holding device.

This object is achieved by a device solved with the features of claim 1.

At least the second clamping part is from the clamping one Engagement can be released from the front by pressing freely rotatable about an axis of the holding device stored. Through the device according to the invention ensures easy assembly of the holding device. The assembly can advantageously by Installation of the wall bracket, subsequent installation of the Supporting element with the clamping parts on the radiator, and finally by attaching it to the radiator attached support elements in the sleeves of the wall bracket respectively. At least one carrying element initially still movable with the pipes connected to an easy adjustment to the position of the Allow wall bracket. When attaching the lower holding devices become the supporting elements initially not yet locked in place by the fixing member also an adjustment of the radiator in the vertical Level. After completing the settings all clamping parts and fixing elements screwed tight.

Alternatively, an assembly process is also conceivable in which, as already shown in the prior art, the wall bracket must first be installed. Then the support element is attached with the first clamping part in the sleeve, the attachment of the Radiators on the corresponding clamping part and the Assembly of the second clamping part from the outside, as well as the Fine adjustment of the second clamping part and clamping the radiator tubes between the two clamping parts instead, the assembly from the front, i.e. from done in the front. In advantageous This can be done retrospectively in the device according to the invention the support elements are adjusted, since the clamping parts in a simple manner from the front of their clamping engagement are releasable and thereby the support element is easily displaceable in its position. This is particularly in the case of inaccuracies in the wall or advantageous if the wall bracket is not precisely mounted. Depending on the version, it is advantageous for assembly just a screwdriver or Allen key needed. Adapting to the appropriate Radiator type is done simply by turning the Clamping part or the clamping parts. There will be none additional adapters or replacement parts required. This is the holding device according to the invention universally applicable and variable to different Radiator types with different pipe spacings or Pipe diameters adjustable.

An advantageous embodiment of the present Invention provides that at least one clamping part at least two pairs of diametrically opposed ones Support zones for different pipe distances or has tube diameter in the circumferential direction are offset from one another. Through that around an axis of rotation rotatable clamp part, it is different due to the dimensioned support zones in surprising easily possible, the holding device to different Pipe distances or pipe diameters from Adapt radiator tubes.

Another advantageous embodiment of the invention Art provides that the clamping parts each a through hole for receiving the axis of rotation. have screw shank of a clamping screw. These through holes form the pivot bearing in Twisting the clamping parts, the smooth bolt shaft forms the axis of rotation. It is freely rotatable under to understand that the clamping part regardless of the Movement of another part, e.g. the screw-in depth a threaded screw, in any position is rotatable. For example, this is the case if the clamping part around the smooth, through the through hole screw neck passed freely movably is.

According to a further embodiment, it is advantageous that the support element has an internal thread on its end face to hold the threaded rod of the clamping screw has, and that at least the second clamping part by the clamping screw is fixed in its position. By tightening the clamping screw after adjustment of the clamping part to the corresponding radiator type this between screw head and radiator tubes clamped, making twisting impossible. The Setting to the appropriate radiator type and subsequent assembly is particularly simple because of this only a screwdriver is required. The Internal thread can advantageously one in the front of the support element embedded nut be.

Another advantageous embodiment of the invention Art provides that the support zones are concave are trained. This eliminates pressure points at the painted radiator tubes avoided and clean grasping the same guaranteed. It is special advantageous if the concave contact zones differ Have radii of curvature. This is one exact adaptation to different pipe diameters possible.

It is also advantageous that the first clamping part is made in one piece with the support element. By the omission of another component is reduced Number of parts to be kept in stock and assembly is easier and faster.

Furthermore, sees an advantageous invention Embodiment before that on the second clamping part clip-on cover to cover the screw head is provided. This lid can be made from any suitable Material made with sufficient spring elasticity be. In particular, thermoplastics are particularly well suited for this. Through the lid getting stuck on what may still be protruding Prevents screw head.

Furthermore, an advantageous embodiment provides that the end face of the support element is angled to the wall, on which the wall mounting is mounted is, whereby the axis of rotation intersects with the Longitudinal axis of the holding device forms. Through this inventive embodiment is the assembly of curved radiators on flat walls or from flat Radiators on curved walls in surprisingly simple Way possible.

Furthermore, an advantageous embodiment provides that the first clamping part has a truncated cone shape arranged diametrically opposite each other has wedge-shaped contact zones. This is especially in one piece with the support element trained clamping part or arranged at an angle to the wall Supporting elements advantageous because here Adaptation to different pipe diameters and Distances in a simple way by a longitudinal difference of the support element can be done in the sleeve. The wedge surfaces can advantageously be light be spherical.

Finally, see an advantageous embodiment before that the sleeve over part of its circumference a larger wall thickness compared to the rest of the Has circumference for receiving the fixing member. Thereby the longitudinal axis of the support element is eccentric to Central axis of the wall attachment. This is beneficial because on the one hand for this geometric design a threaded bolt sufficient wall thickness for cutting an internal thread is present and the other one unnecessary weight gain due to the holding device an unnecessarily large wall thickness is avoided.
