Definitions
- the invention relates to a slot outlet with an outlet opening delimited by channel walls in a housing, shaft or the like.
- slot outlets are known in many forms and designs. As a rule, they have two channel walls, between which a roller with throughflow sections is arranged. As an example, reference is made to EP 0 239 854 or DE-OS 25 53 196. These rollers require separate storage because they have to be rotatable. Furthermore, the slot outlet must be kept relatively wide so that the rollers have a sufficient diameter and their bearings have a sufficient wall thickness.
- the present invention has for its object a
- two differently configured guide profiles are inserted opposite each other in the outlet opening, each of which has a surface contour for guiding an air flow.
- These guide profiles have the task of guiding the air flow in certain directions, i.e. to determine the outlet opening. Therefore, the guide profiles have a certain, desired surface contour for guiding the air flow.
- the guide profiles are preferably designed such that they can be fixed on one and also on the other duct wall and the direction of the respective air flow is thereby changed. Furthermore, they should also be able to be used in a rotated manner, for example on the same duct wall, and thereby influence the air flow differently. This configuration considerably reduces the manufacturing and assembly costs for a slot outlet, since only two guide profiles or two guide profiles connected to form a guide profile insert are required for a wide variety of air flows.
- both guide profiles act preferentially to guide the air flow, i.e. together to design the blow-out opening.
- the one guide profile consists of a guide strip with an integrally formed guide foot and the other guide profile consists of a bulge with an integrally formed strip.
- the arch and the guide foot lie opposite each other, so that a guide foot instep is roughly modeled on the curvature of the arch.
- This configuration ensures various options for guiding an air flow. If, for example, bulge and guide foot lie inside between the channel walls and the guide strips face each other, there is no distraction when blowing out Air flow instead, so that the air flow emerges vertically downwards.
- the air flows onto the guide foot and is deflected in one direction.
- the direction can also be selected by exchanging the guide profiles.
- a further air guide lamella is provided between the guide profiles or between a duct wall and a guide profile.
- a particularly effective embodiment of the invention is given when the guide profiles and possibly also the air guide blades are combined together for use.
- This insert can be rotated horizontally or vertically and the blowout opening direction can be determined as required.
- the insert should also be removably inserted between the channel walls, which is done by means of appropriate latching devices, such as tongue and groove mechanisms.
- channel walls are usually made of the material of the housing, i.e. mostly made of metal, it has proven to be advantageous to insert corresponding edge profiles between the guide profiles and the channel walls.
- edge profiles and also the guide profiles can optionally consist of plastic or aluminum. This also makes production and assembly easier, since only two different profile types, edge profile and web, are required for the slot outlet in order to create a distance via spacer sleeves so that several guide profile inserts can be arranged side by side.
- the edge profile has support strips, with each support strip having a guide profile.
- the support strips can, for example, form locking bosses and the guide profiles so that the guide profiles are simply pushed between the support strips, in particular as an insert, with the support strips extending outwards soft and snap into the indentations after the guide profiles have been inserted, or snap the springs into the grooves.
- slot outlet can be made in any length by means of two profile types, edge profile and web. This enables individual adaptation due to the width and length of the slot outlet with very little manufacturing effort.
- the air flow can be deflected in three different directions, downwards, to the right and to the left.
- a light fitting is assigned to the slot outlet, it being possible for heat generated by, for example, a fluorescent tube to be dissipated or extracted through perforated slots by means of an outlet connector.
- This removal can be controlled by a slider mounted on holding rails. This control can be carried out continuously by closing the perforated slots more or less with the slotted slide.
- the perforated slots and also the corresponding slotted slide can be provided with slots, holes or other openings.
- the perforated slots are preferably provided in the base plate of the housing, the ones adjoining there preferably being bent Form a side bracket at each end.
- At least one fluorescent tube can be attached to the base plate opposite the outlet connector via a support. This ensures that the bevelled arrangement of the side walls means that the air heated by the fluorescent tubes is carried upwards by the temperature differences alone and is discharged through the perforated slots via the outlet connection.
- the removal of air through the perforated slots can be supported by suction devices, not shown here.
- the housing can also be designed in a parabolic shape in order to achieve better light beam guidance and reflection of the light in the room.
- a shaft preferably to the right and left of the side walls of the housing, is fixed via a support bracket attached to the base plate and the attachment bracket.
- This shaft is preferably very narrow in order to appear as inconspicuous as possible. This also ensures that a maximum of warm or cold air can be introduced into a room.
- the air to be discharged can be deflected in three main directions by the guide profiles or inserts described above.
- the guide profile inserts are detachable and rotatable between an edge profile and a web.
- edge profiles are preferably connected to the floor and are supported at the same time with clamping strips on the side walls of the shaft or on a support strip.
- the possibility of also inserting several webs between the edge profiles by means of spacer sleeves creates several openings which are possible for the guide profile insert, so that several guide profile inserts can be inserted next to one another. This provides a particularly effective embodiment of the invention, since different air flows can be combined by using the guide profile.
- slot outlet Furthermore, a major advantage of the slot outlet is that the air flow can be guided directly along the ceiling via the guide profile inserts and thus induction of room air on the ceiling is excluded, which has so far resulted in severe contamination of the ceiling.
- the special feature of the present invention is to be seen in the fact that the heat is removed from at least one fluorescent tube and at the same time the supply of cool air can be combined through the guide profile inserts.
- This particular arrangement ensures, on the one hand, a cooling process and a supply of fresh air to a room and, on the other hand, in the case of heating, by locking the perforated slots, that warm air can be introduced into the room, so that a heating process is also supported.
- the edge profile is seated on a special cover frame which, on the one hand, can be folded or designed differently in order to give the air outlet a specific design.
- the entire arrangement of the lighting device can be used on or in a ceiling. It is also particularly suitable for installation in false ceilings or on other profiles.
- a lamella frame can be provided between the fastening angle of the side walls of the housing, which supports an optical design and special light guidance of the housing and thereby integrates the air outlet in a ceiling.

- the openings 7 are preferably arranged to the left and right of the outlet opening 3.
- An edge profile 8a, 8b which is preferably of identical design, is pushed onto each channel wall 4 or 5.
- This edge profile 8a, 8b can be made of plastic or aluminum, for example. In the present exemplary embodiment, it has a plate part 9, from which a clamping strip 10 is folded. In the position of use, this clamping strip 10 overlaps the channel wall 4 or 5, as a result of which the edge profile 8a, 8b is fixed on the channel wall 4 or 5.
- a support strip 11 is connected to the plate part 9, forming a stop 22, which, according to FIGS. 1 and 2, is partially of different thickness due to an accumulation of material. This accumulation of material can form a detent boss 12 to a certain extent.
- Each support strip 11 has its own guide profile 13 or 14.
- the guide profile 13 consists essentially of a conductive strip 15, "which is preferably an indentation 16 corresponding to the locking boss 12 includes, on the conductive strip 15 includes a Leitfuß 17 on, the voltage cross-section a ⁇ ff- 18 between the two edge profiles 8a and 8b narrows.
