Description

The invention relates to a fastening device for fixing a heating or cooling body with retaining tabs, consisting at least of a stationary wall bracket and a relative to the wall bracket height-adjustable retaining bracket with a clamping element.

Generic fastening devices are preferably used for the installation of heating or cooling bodies, in particular in plate form. The fasteners are used to make a wall mounting, with a secure mounting of the heating or cooling body is required. Due to component tolerances, it is necessary in this case that the fastening device can be adapted to the dimensions of the heating or cooling body and even with larger tolerances secure mounting of the heating or cooling body is possible. In order to hold the heaters or heatsink with the aid of the fastening device, these have retaining tabs which directly in the fastening device, which typically consists of a fixed wall bracket and a relative to the wall bracket height-adjustable holding bracket to record. In order to take account of different heights of the heating or cooling body, in this case there is usually the possibility to consider the distance of the retaining tabs with the aid of a latchable retaining bracket. Although the known fastening devices or holding devices satisfactorily fulfill the intended use, there is an additional need, due to legal requirements, to prevent lateral slipping of the heating or cooling body as well as lifting.

The present invention is therefore based on the object to provide an improved fastening device which allows secure fixing of the heating or cooling body and at the same time ensures that the heating or cooling body can not experience relative movement relative to the fastening device.

According to the invention is provided for solving the problem that the wall bracket has at least one recess for receiving a retaining tab and the retaining bracket with a hold-down clamp element as an upper retaining tab additionally engages at least partially latching. Further advantageous embodiments of the invention are given by the dependent claims.

Compared with the fastening devices known from the prior art, a fastening is preferred in the embodiment according to the invention, which ensures secure fixing of the retaining tabs in the fastening device. For this purpose, a first retaining tab is suspended in a recess of the wall bracket and with the help of a height-adjustable support bracket with a hold-down another usually elevated holding tab additionally encompassed at least partially. By this type of installation, the vertical position of the radiator is fixed in such a way that it can not be raised. Just by the unintentional lifting of the radiator was a great danger that this could be completely detached from the wall bracket and resulted in personal injury. However, the novel fastening device prevents by the formation of a notching of the retaining tabs from the wall bracket. At the same time it is ensured by the hold-down by partially gripping and locking an upper retaining tab that a lateral displacement of the heating or cooling body relative to the wall bracket is excluded. These measures thus ensure that the heating or cooling body is fixed immovably both horizontally and vertically in the wall bracket.

In an embodiment of the invention, it is provided that the wall bracket has two legs of different lengths. The two legs are initially used to guide the holding console safely, the longer leg is further equipped with recesses that allow a recording of the heating or cooling body in the wall bracket. In order to make the assembly as simple as possible, it is provided that the wall bracket in the lower and / or upper region has a recess with a recess in which the retaining tabs einrastend einliegen. This measure ensures that the heating or cooling body can not slip forward from the existing recesses. At the same time it is ensured by the depression that there is a firm locking of the retaining tabs in the recess. Preferably, such a lock in the lower region, that is required at the lower retaining tab, but may optionally also be provided at the upper retaining tabs. In addition, there is a locking of the retaining tabs in the recesses of the wall bracket by the hold-down, which additionally surrounds the upper retaining tab latching at least partially. Snap-in means that the holding-down device with toothed elements absorbs portions of the holding lug and thus fixes it.

In order to accommodate the attachment device to any structural tolerances or possibly different sizes of the heating or cooling body with slightly different height dimensions of the retaining tabs in the fastening device, it is possible to shift the upper support bracket vertically. For this purpose, the wall console in the upper area in the parallel legs equipped with horizontally arranged openings at equidistant intervals. Furthermore, the wall bracket has perpendicular to the openings at least one guide web or a fold for the clamping element and the hold-down. The retaining bracket itself consists of a U-shaped bracket with diametrically opposite outwardly projecting locking lugs and a guide portion. The guide portion serves to guide the retaining bracket within the two legs of the wall bracket safely, while the bracket can engage with its protruding locking lugs in the existing openings of the two legs of the wall bracket. By squeezing the U-shaped bracket, the protruding locking lugs are displaced inwards relative to the apertures of the wall bracket, so that the retaining bracket is variably adjustable in height. According to the predetermined number of openings in the legs of the wall bracket is thus possible to provide a height adjustment of the retaining bracket in an area over several centimeters. In this case, there is also the possibility that a fine adjustment in the height adjustment can be done by varying the distance of the individual openings or arrangement in the same or different heights. By squeezing the expiring limb of the U-shaped bracket in this case it is possible to push out the locking lugs from the individual breakthroughs and make a height adjustment of the U-shaped bracket by pulling or pushing. As soon as the pressure on the two free leg ends of the U-shaped bracket no longer exists, by pressing or pulling the locking lugs can engage in the next breakthrough, so that an individual height adjustment is possible. Such a height adjustment is necessary because due to component tolerances of the heating or cooling body an individual adjustment is required. To make the adjustment as easy as possible, the U-shaped bracket has a guide portion which is arranged between the two legs of the wall bracket. The guide is hereby completed by the fact that the wall bracket has perpendicular to the openings at least one guide web and a fold for the clamping element and the hold-down. Thus, the guide section is behind the guide bar and the fold of the wall bracket and can only be adjusted in height. In addition, there is the possibility that with the help of a bolt, which is rotatably but stationary, for example, relative to the bracket, in addition, a height adjustment of the hold-down takes place. For this purpose, the stationary but rotatably mounted bolt is screwed into a thread of the blank holder, so that upon further rotation of the hold-down relative to the fixed position of the bolt in height is adjustable.

The guide is hereby further supported by the fact that the hold-down also has a guide element which rests directly on the fold and the guide bar. In this construction, the hold-down and the U-shaped bracket forms a unit, wherein the connection is made by the bracket having two claws, which engage through an opening of the hold-down. By squeezing the retaining claws here is the possibility to separate the two parts. Thus, the hold-down and the U-shaped bracket can slide in the wall bracket, the hold-down and the bracket on a guide portion, with an optimal adjustment of the height of the support bracket is possible because the integrally formed on each leg locking lugs of the bracket in the same or different height are arranged and thus there is the possibility of a fine adjustment.

In this case, the hold-down has a double-folded end region, which has a sawtooth-shaped structure along the last fold. The sawtooth-shaped structure is intended to laterally encompass a portion of the upper retaining tab of the heating or cooling body. The retaining tab here consists of a U-shaped bracket, which is connected with its ends directly to the heating or cooling body. The sawtooth-shaped structure can thus encompass the retaining lug laterally relative to the base, so there is the possibility that the hold-down device with the aid of the sawtooth-shaped structure detects the adjacent sections of the base in such a way that a lateral displacement of the heating or cooling body is prevented.

The particular advantage of the present invention is that a heating or cooling body in the fastening device according to the invention not only hooked with retaining tabs, but at least one retaining tab is additionally clasped, whereby lifting of the heating or cooling body is prevented. Furthermore, a portion of the U-shaped retaining tab is detected by the sawtooth-shaped structure of the hold-down, so that a lateral displacement of the heating or cooling body is prevented. Thus, an optimal centering of the heating or cooling body is achieved and thus a secure anchoring, so that unintentional disengagement of the heating or cooling body is avoided from the fastening device.
