IjU £ tfi 1 termatte for dedusting heated; room air

The innovation concerns a filter mat for removing dust from heated room air * and heating equipment, with a pliable filter cloth made of matted or interwoven fibers. '.' .. _V: ■ - '. ■ ■ /.."'■''''''' -: ■ ^-;

The new filter mat is used for separation Dust from the area, in particular from radiators, soaring

For cleaning the top of using solid, liquid or gaseous fuels due to heated stoves of the thermal GefMile exiting warm air is a

Filter cloth known, which consists of glass fibers that. are slightly matted and connected by means of an adhesive. This filter cloth is based on the size of the top of the Oven and the dimensions of the oven cover Trimmed in place and attached to the inside of the Cover of the heater attached. The fastening is done by means of long, band-shaped clamping springs, which Cover the cut filter cloth and use Screws are screwed to the furnace cover. In the same way, the filter cloth is from the inside in front of the Air outlet openings of warm air heaters attached »Apart from the possibility of using the filter cloth a special adhesive to stick to the covers, is also an attachment by means of small, powerful permanent magnets, with the help of which the filter is clamped at several points on the furnace cover, is known. No However, these known types of attachment is suitable for a filter cloth of the type mentioned on the top to attach a central heating element «

The innovation is therefore based on the task of a an air-permeable, interwoven or felted fibers made of suitable material filter mat to train existing dust filter in such a way that it is intended for use in central heating radiators

is suitable.

According to the innovation, this task is "solved by longitudinal of the edge of the filter mat arranged in a row next to each other, weights at a distance from each other · The new filter mat then consists of a multiple or less long strips of filter material, the width of which is the depth of the radiator, plus a front one And the rear verge corresponds. There is a row of weights that serve as edge weights each of the edge strips so that those with on the radiator hanging down on the front and back of the applied filter mat, and the whole air filter through the weights is tightened. This way, "lets see the central heating body Cover over its entire length with the suggested filter mat like a hood and back overhanging edge strips cause the filter to remove most of the rising warm air is enforced. The weights arranged along the edges hold the filter mat firmly in place. These weights can for example be glued or riveted to the filter mat or attached in some other way. Through the Weights do not prevent the filter mat from being folded up - for packaging, for example - they leave one Cleaning of the filter mat by washing out the filter material is easy.

stand from each other, the innovation according to the Shorten the filter mat to any desired length to adapt it to the length of the radiators; Furthermore This enables edge recesses (for example on the rear edge strips of the filter mat) to be cut out at the points on which the central heating body is by means of horizontal struts are attached to the wall

In an advantageous embodiment of the innovation, the weights are within a along the edge of the filter mat guided fold _β arranged This fold is made by folding over and sewing or gluing of the outermost edge of the filter mat? the fold can just as well be designed as a hem. This measure increases the durability of the filter mat, prevents it from being warped at the fastening points and effectively prevents the weights from being torn out - especially during the washing process . prevents. «... ...".

The weights can also be placed inside one along the edge attached to the filter mat, consisting of a foldable band Edging be arranged »The tape is advantageous made of heat-resistant, heat-sealable plastic and it is welded to the edge of the filter mat.

version or in the form of a piping sewn or glued on is. Inside the band (piping) are at a distance from each other the weights that are attached to the tape are. In addition to the extension that can be achieved through this band During the service life of the filter mat, the weights, which are completely covered by the tape, are hidden from view, as is the case with unclad ones Radiators is felt to be advantageous in view of the transparent Pilterra material.

In a preferred embodiment, pieces of lead sitting inside a fabric tube serve as weights for fastening this fabric tube with the pieces of lead is drawn into the fold or the border on the filter mat; Such a lead cord can also be created in the simplest manner by means of zigzag stitches using a textile thread be sewn on. The use of a commercially available lead cord or a lead tape allows the innovation to be manufactured very inexpensively *

The fabric hose by means of holding devices is expedient attached to the filter mat. This comes into consideration when the lead cord is in a fold or edging has moved in. The attachment (for example by means of Rivets or staples) prevents the Lead cord. The fastening does not take place advantageously

only at the ends, but it can also be done at certain intervals along the edge of the filter mat the falling out of the lead cords, too, with shortened or filter mats provided with edge recesses impossible do"

Three embodiments of the. Innovations are shown in the drawings and are described in more detail below * It sseigen:

Figure 1 is an innovation according to the filter mat of rectangular Floor plan, with folds arranged on the long sides to hold weights, in plan view, partially cut off;

Figure 3 shows the edge area of another embodiment.

form of innovation, in which the weights * are arranged inside an enclosure, in a cross section;

Figure 4 shows the edge area of a further embodiment, in which a lead cord by means of of a zigzag stitch is attached to the dust filter, in a cross section.

A dust filter in the form of a filter mat 1, made for example of matted, thin glass fibers a plan of an elongated rectangle (compare Figure 1, in which one end of such a filter mat 1 is shown). Along the two edges of the 2 Long sides of the filter mat 1 is each a hollow fold 3 is attached, which by turning over the edge areas of the Filter mat 1 is won * The fold 3 is by means of a zigzag seam 4 laid parallel to the edge 2 in their position fixed »Inside the fold 3 lies over the entire length the filter mat 1 is a fabric tube 5, in which weights 6 in the form of pieces of lead at a distance from one another sit. The ends of the fabric hose are provided with holding devices 7, for example in the form of rivets the filter mat 1 connected.

In another embodiment - compare FIG. 3 along the edge of the filter mat 1 an enclosure attached, in the interior of which the fabric tube 5 with the Weights 6 is arranged. This mount 8 consists of

a flexible band folded at an angle of 180 degrees, between the longitudinal edges 9 of which the edge 2 of the filter mat 1 lies.

Figure 4 shows the attachment of the fabric tube 5 with the weights 6 on the edge of the filter mat 1 by means of a Fadens TO, which wraps around the fabric tube 5 and is passed through the filter mat 1.

The innovation includes a removable dust filter for central heating radiators suggested. This dust filter does not need any fastening devices because it - with a Provide edge weighting - ■ simply hung over the radiator will * It is inexpensive to manufacture; a particular advantage is the possibility of using the dust filter Adaptation to the length of the radiator to be shortened as required and to cut recesses at every point on its edge * V.
