Facility for conveying or treating
of air with one on a support in
an air duct retractable air delivery or treatment element.

The present invention relates to a device for conveying or treating air with one on one
Carrier in an air duct insertable air delivery or treatment member.

In known devices of this type, the frame-

or trough-shaped carriers for the air conveying or air treatment

for
organ z. B./an air filter, heater, cooler or

fan, can only be pushed into the air duct from a given side of the housing. This is injustice! The consequence of this is that the air duct section intended to accommodate the carrier must be produced in such a way that dafl the housing opening for inserting the carrier and

109832/0747

the guide elements, such as guide rails, to a specific one Place come to lie in the air duct section, which is accessible when the air duct is installed. From the For the same reason, when installing the air duct section, you must ensure that it is in the prescribed Position is attached «

^ The purpose of the invention is to avoid the disadvantages mentioned. According to the invention, the device for conveying or treating air is characterized in that in the air duct a right-angled frame lying transversely to the air flow is arranged for receiving the carrier, on which frame the Carrier can optionally be pushed into and pulled out of the air duct on at least three sides transversely to the air flow is.

The invention will then be explained with reference to the drawing, in which FIGS. 1 to 3 are an isometric illustration of three Embodiments of the devices show, for example explained

In Fig. 1, a frame 1 consisting of angle profiles connected to one another at right angles is shown, which, together with cover plates (not shown), form a housing part of an air duct assembled according to a modular system for a ventilation or air conditioning system · For example

109832/0747

can the top and bottom of the frame 1 over Legs 2 connected sections of the air duct, while on the legs 3 of the four side surfaces Cover plates are attached.

On the upper side of the frame 1, a flat, right-angled frame 4 is attached, which is assembled from profiles with an approximately Z-shaped cross-section, the web 5 of which is angled perpendicular to the two legs 6 and 7. The upper legs 6 of the frame k are connected to the legs 2 of the frame 1, for example welded. The webs 5 are spaced from the legs 3 of the frame 1 at such a distance that heads of threaded bolts 9, designed as wing nuts 8, are inserted into corresponding threaded bores of the webs 5 can be screwed in, find space between the webs 5 and the legs 3 and the threaded bolts 9 can be turned a few turns outwards before the wing nuts 8 strike the inner surface of the legs 3.

Each of the webs 5 is provided with, for example, two threaded bolts 9, each of which is used to attach an angle profile 10 per web 5 are used «The angle profiles 10 have on one of their legs 11 slotted holes 12 for the threaded bolts 9 so that after loosening the threaded bolt by turning it

109832/0747

dar on them attached wing nuts 8 each angle profile 10 can be removed downwards. The slot holes 12 are also arranged so that in the screwed-on state the other leg 13 of each angle profile 10 with the lower leg 7 of the corresponding profile of the frame 4 has a groove 1 ″ 4 forms.

A box-shaped or drawer-shaped carrier 15 is used to hold an air delivery or treatment element which, in the exemplary embodiment shown, is designed as a filter 16 arranged in the shape of a wave. The carrier 15 is provided on its upper side with a protruding, flat edge 17 which can be ^{pushed into the grooves I 1} I as a guide rail.

If a fully assembled air duct is to be provided with an air filter, a side cover plate, namely the most accessible side cover plate, of the frame 1 attached to the intended location in the air duct is removed. The two threaded bolts 9 arranged on this string in the frame k are then loosened somewhat by turning the wing nuts 8 from below, so that the angle profile 10 can be removed downwards. The carrier 15 provided with the air filter 16 is now pushed like a drawer into the two grooves 14 open on the relevant side until it comes to rest with its rear edge in the rear groove. The previously removed angular

profile 10 pushed back onto the threaded bolts 9 from below so that its legs 12 and 13 meet the edge 17 of the After tightening the threaded bolts 9, the carrier 15 is held on all sides on its edge 17, finally the side cover plate is attached to the frame 1 again,

The device described thus allows the carrier for an air conveying or treatment element, such as an air filter, Air humidifier or the like, regardless of the installation of the air duct from an easily accessible point of the To attach the air duct or to remove it for cleaning or renewal. It is therefore not advantageous more necessary in the manufacture of the air handling element for receiving the air conveyor certain air duct element or when installing the air duct on the local arrangement of the air duct or on any existing local Pay attention to obstacles such as wall surfaces etc. near the air duct. Rather, they can be used to record The frame frames provided for the air conveying or treatment element are prefabricated in larger series and without any special ones Instructions are assembled as long as at least one of the side surfaces of the frame is free in the assembled state is accessible, since the carrier for the air conveying or treatment element, as shown in Fig. 1 in part by dash-dotted lines.

is made, can be used in the same way from all four sides of the frame.

It is readily apparent that the cross-section of the frame structure 1, and thus the plan, the carrier 15 can be square or rectangular, furthermore, the air in the device shown in Fig. 1 can also be on the upper ^ side of the frame and flow through one of the side surfaces flow out, or vice versa. It is then still possible to insert the carrier 15 from three different sides insert the frame 1 »

Another embodiment of the device according to FIG ^{, which in turn form a groove I 1} I- with the lower legs 7 of the frame 4, As a guide element for ■ a box-shaped carrier 18 in which the air filter 16 is housed, another loose frame 19 is provided, which consists of four connected at right angles U-profiles is composed with an outwardly facing profile opening and which is located with one of the profile legs in the grooves 14. The box-shaped carrier 18 is, for example, at two corners

109837 / Π747 BADORIQlNAt

of the frame 19 each connected via a joint 20 "Instead can also be along an edge of the bottom surface of the carrier 18 and the edge of one of the profiles of the frame 19, a hinge is arranged. the axis formed by the hinge can therefore be pivoted forward through 180 °. To hold the carrier 18 on the frame 19 in the swiveled into the interior of the frame 1 ^ In the position shown in phantom, the carrier 18 is provided with a resilient tab 21. There is also a support 22 provided, ure the carrier 18 in its forwardly pivoted Support location.

It can be seen from Fig. 2 that the frame 19, on which the carrier 18 is articulated, after removing one of the side cover plates, not shown, and the one below Angle profile 10 of each of the four side surfaces of the frame 1 are inserted into this can. The articulated arrangement of the carrier 18 on the frame 19 also allows a particularly simple installation and removal of the im Carrier 18 located air filter 16 or another, before seen air delivery or handling organ,

In the embodiment shown in Fig. 3 has the attached to the top of the frame 1 frame 4 different profiles. Two opposite each other arranged profiles 24 are approximately Z-shaped and with

a lower tavern 25 provided as a guide rail. The other two profiles 26 are as angle profiles formed, with its vertical leg is shorter than the corresponding web 23 of the Z-profiles 24, a loose, Another frame 27 composed of U-profiles, the grooves of which point outwards, reads with two of its opposite one another U-profiles on the lower legs 25 of the Z-profiles 24. A box-shaped support 28 for the air filter 16 is provided on two upper edges with further U-profiles 29, the inwardly facing grooves for receiving the lower Legs of two U-profiles of the frame 27 are provided »

In this device, after removing the corresponding side cover plate (not shown), the carrier 28 can also be inserted as desired on one of the four side surfaces, with one insertion direction according to the arrows 30 of the frame 27 together with the carrier 28 on the lower legs 25 of the Z-profiles 24 and with an insertion direction according to FIG the arrows 31 of the carrier 28 slides on the frame 27.
