Description

The present invention relates to a holding device for a radiator according to the characteristics of the Preamble of claim 1.

A known device of this type (GB 2269659 A) enables a loose to compensate for thermal expansion Placing radiators on a wall bracket, which is a support element adjustable perpendicular to the wall having; a clamping device from a first and a second clamping part is between adjacent ones Radiator tubes attached and so on the support member filable that additional measures against Taking off is secured. A serves as a safety catch Connection part made of elastic plastic, which Thermal expansion of the radiator compared to the wall mounting not disabled.

In contrast, a fixed holding device according to the invention are created for radiators which nevertheless variable on different types of radiators adjustable and easy to assemble.

This object is achieved by the features solved in the characterizing part of claim 1.

Characterized in that the first clamping part firmly with the support member connected, results from the clamping Interaction with the second clamping part a clear one Fixing the radiator in relation to the support element the wall mounting. The fact that the support element longitudinally displaceable and lockable by a fixing element engages in a sleeve of the wall mounting, can the wall distance can be set variably and at any time can be easily readjusted.

For the assembly there is the possibility of the support element either by pre-assembly on the radiator fasten in order to then push it into the sleeve or the radiator on the first already wall-mounted Support the clamping part until the second clamping part is screwed so that adjacent radiator tubes are fixed between the two clamping parts.

When mounting using several holding devices is initially only a support element between the Radiator tubes attached; the others will be first locked after it has succeeded, the wall-fixed Assign sleeves and insert them into them.

The universal applicability of the invention Holding device serves in particular the feature that at least one clamping part at least two pairs of themselves diametrically opposed support zones for different Has pipe distances or pipe diameter, which are offset from one another in the circumferential direction. By this makes it easy to turn the clamping parts possible that these are easily sent to different Pipe distances or pipe diameters of radiator pipes can be adjusted.

An advantageous embodiment provides that the Clamp parts each have a through hole for receiving of a screw neck forming the axis of rotation Have clamping screw. Form the through holes the pivot bearing when turning the clamping parts, with a smooth screw neck portion the axis of rotation forms.

According to a further embodiment it is provided 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 his.

Because the contact zones of the clamping parts are concave are formed, pressure marks on the painted Avoided radiator tubes and grasped them properly guaranteed. It is particularly advantageous if the concave contact zones have different radii of curvature have an exact adaptation to different To enable pipe diameter.

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.

According to another embodiment, the second Clamping part an attachable cover to cover the Screw head provided. This lid can be made any suitable material with sufficient spring elasticity be made. In particular thermoplastic Plastics are particularly good for this suitable. The lid will get caught the possibly protruding screw head prevented.

Characterized in that the end face of the support element advantageously at an angle to the wall on which the wall mounting is mounted, arranged, forms the Axis of rotation an intersection with the longitudinal axis of the Holding device. Through this measure, the assembly of curved radiators on flat walls or of level radiators on vaulted walls in surprising easily 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 particularly so in one piece with the support element Clamping part or with support elements arranged at an angle to the wall advantageous because here the adaptation to different Pipe diameters and distances in simple Way through a longitudinal difference of the support element in the sleeve can be done. The wedge surfaces can advantageously be slightly spherical.

Finally, the sleeve can be over part of her Larger wall thickness compared to the rest of the circumference for receiving the fixing member. As a result, the longitudinal axis of the support element is eccentric to the central axis of the wall mounting. This is advantageous because of this geometry on the one hand for 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.
