Description

Slotted drain

Technical field

The invention relates to a slot-shaped outlet with an outlet opening delimited by channel walls in a housing, shaft or the like, wherein in the outlet opening two different guide profiles are arranged opposite one another, having an outer contour for guiding the air flow.

BACKGROUND OF THE INVENTION

Such slotted outlets are known in many shapes and embodiments. As a rule, these slotted outlets are provided with two channel walls between which a cylinder with through air slots is arranged. By way of example, slotted outlets are described in EP 0 239 854 or DE-OS 25 53 196. These cylinders require a special bearing because they must be rotatable. Further, the slot outlet must be relatively wide so that the rollers can have a sufficient diameter and their bearing can have sufficiently thick walls.

SUMMARY OF THE INVENTION [0007] In view of these drawbacks, it is the object of the present invention to provide a slot-outlet design of the kind mentioned which, by the simplest means, allows to influence the air flow in various ways and which is at the same time narrow. In addition, the assembly and manufacture of this slot-out drain should be substantially facilitated.

SUMMARY OF THE INVENTION

This problem is solved and the drawbacks of the known slot-type outlets of this kind are largely eliminated by the slot-type outlet according to the invention, characterized in that two different guide profiles are arranged opposite one another in the outlet opening.

The purpose of these guide profiles is to deflect the air flow into certain directions, i.e. to define an outlet opening. For this purpose, the guide profiles have a suitable shape which allows the air flow to be guided.

The guide profiles are preferably designed so that they can be mounted on one and also on the other channel wall and thus the direction of the air flow can be changed. In addition, these guide profiles can also be rotated on a given channel wall, whereby the air flow can be influenced in a different way. This embodiment also greatly reduces the cost of manufacturing and assembling the slotted outlet, since only two guide profiles or two guide profiles connected to the guide profile insert are required to adjust the different air flows. Thus, the guide profile can be connected to the channel wall in a rotated or inverted position, and thus the direction of the air flow can be changed.

Preferably, the two guide profiles cooperate in conducting the air flow, i.e. in the discharge opening. In a preferred embodiment, the first guide profile consists of a guide strip with a shaped guide shoe and the second guide profile consists of a convex bulge with a shaped strip, wherein the convex bulge and the guide shoe are arranged opposite each other so that the instep of the guide shoe is approximately opposite the bulge.

This design provides a variety of air flow options. If, for example, the convex bulges and the guide foot are located inside and at the mouth of the outlet opening the strips are opposed, there is no deflection of the air flow so that the air stream exits vertically downwards.

Conversely, if the convex bulge and the guide foot are arranged at the mouth of the outlet orifice, the air flow impinges on the guide foot and is deflected sideways. The deflection direction can be selected by interchanging the guide profiles.

In order to further influence the air flow, at least one air guide lamella is arranged between the channel wall and the guide profile or between two guide profiles.

Another very advantageous embodiment of the slot-shaped drain according to the invention is that the guide profiles and possibly also the air guide fins are combined in a common guide profile insert. The guide profile insert can be inserted into the air outlet rotated about a horizontal or vertical axis so that the direction of the air flow exiting the air outlet can be selected as desired. For this reason, it is also necessary for the guide profile insert to be removably mounted between the channel walls, which can be ensured by suitable latching mechanisms, for example by a combination of a spring with a groove.

Since the channel walls are usually of the same material as the housing, i.e. metal, it has proved to be an embodiment that an edge profile is fixed and / or detachably arranged between the channel walls and the guide profile. These edge profiles as well as the guide profiles may optionally be of plastic or aluminum. In this case too, production and assembly are simplified, since only two different guide profiles, an edge profile and a bridge are required for a single slot outlet, which allow the spacings to be spaced so that multiple guide profile inserts can be arranged side by side. The opposite edge profiles are thus connected to each other by means of fasteners and spacer sleeves.

Corresponding clamping strips are used for attaching the edge profiles, by means of which the edge profiles are detachably connected to the respective channel wall. The edge profile is thus firmly and / or detachably connected to the channel wall or is supported against the channel wall.

The edge profile is preferably provided with support strips which support the guide profiles. For better attachment and also to the aforementioned snap connection, snap ridges can be formed on the support strips and depressions formed in the guide profiles so that the guide profiles, especially in the form of a guide profile insert are simply inserted between the carrier strips, which are avoided outwards and, after insertion of the guide profiles, engage in the recesses or the springs engage in the grooves.

A further advantage of the invention is that by means of two types of profiles, an edge profile and a bridge, a slot outlet of any length can be produced. In this way, individual adaptation of the width and length of the slot outlet is possible at low production costs.

Due to the ability to engage multiple guide profile inserts side by side and / or one after the other in the slotted outlet, the air flow can be deflected in three different directions, i.e., down, right and left.

Another advantageous embodiment of the slot-shaped drain according to the invention is characterized in that grooves are formed in the carrier strips and springs are formed on the side walls of the guide profiles, which in the working position fit into the grooves of the edge profiles. at least one bridge attached.

The bridge preferably consists of two profiles, the upper thicker profile having a rounded upper end and the lower profile having grooves on both sides.

A particularly advantageous embodiment consists in that the guide profiles and possibly also the air guide fins are connected to each other in the guide profile insert by at least one end wall, which makes it possible to incorporate the guide profile insert as a whole.

The guide profile insert is preferably snap-fitable between the channel walls or between the edge profiles, between which and / or bridges at least two such guide profile inserts can be arranged side by side and / or one behind the other.

The edge profile is further preferably provided with at least one cover frame having a rounded, curved or similar outer shape and which is fixed or removably connected to the edge profile by the fastening elements.

In a further embodiment of the slot-shaped outlet according to the invention, it comprises a lighting body, whereby the heat radiated by, for example, a lighting tube can be removed or exhausted through the slot opening. This discharge can be controlled by means of a sliding gate which is mounted on the supporting rails. This control may be continuous such that the slot opening is more or less closed by the slot gate. The slotted outlet is provided with a housing in which at least one light, preferably an illumination tube, is arranged and an air outlet is associated with this light. The aforementioned air extraction device is also associated with the light. Said housing is provided with a bottom wall in which a slotted opening is provided with a sliding slide which is supported on the supporting rails and continuously closes and / or opens the slotted opening.

The slit opening as well as the respective sliding slide may be provided with slots, holes or other openings.

The slotted opening is preferably formed in the bottom wall of the housing at the point where the curved side walls of the housing are provided with attachment angles at the edges. On the side opposite to the drain pipe, at least one lighting tube can be attached to the beam at the bottom wall. In this way, it is ensured that the air heated by the illumination tubes is led upwards through the curved side walls already due to the different temperature, and is further discharged through the slotted opening through the exhaust pipe. The exhaust of air through the slot opening *% can be supported by a suction device (not shown).

In practical terms, the bottom wall is provided with a drain pipe around the aperture opening, with beams on which the lighting tubes are arranged on the bottom wall to the left and right of the aperture opening. At least one side wall, which is provided with a mounting bracket at its edge, protrudes from the bottom wall.

It is further contemplated that the skin can also be made parabolic to provide better orientation and reflection of light into space.

By means of a mounting bracket and a support bracket which is connected to the bottom wall, at least one shaft is fixed to the side of the housing, in which a slotted outlet is arranged. Said shafts are preferably attached to the housing on both sides thereof. The shaft is preferably very narrow in order to be as low as possible visible. At the same time, however, it is ensured that the maximum amount of hot or cold air can be supplied to the space.

This is made possible by the fact that, for example, the cooled air is introduced into the shaft through an opening in the shaft, to which the inlet pipe is connected. Air is then discharged through the air outlet through the slot outlet into the space.

In practice, this is done by providing an opening in the outer side wall of the shaft into which the inlet nozzle opens.

In this case, the exhaust air can be deviated in three different main directions by the above-described guide profiles or guide profile inserts. The guide profile inserts are again detachably and with the possibility of turning or reversing inserted between the edge profile and the bridge.

.¼

The edge profiles are preferably connected to the bottom of the shaft and are simultaneously supported by clamping strips on the walls of the shaft or on the supporting strips.

Due to the possibility of arranging more bridges between the edge profiles by means of spacers, more places for inserting the guide profile inserts are obtained, so that more of these guide profile inserts can be inserted side by side. In this way, an extremely efficient embodiment of the invention is achieved, since different combinations of air flow can be achieved by means of guiding profile inserts.

If several guide profile inserts are arranged one after the other and / or side by side, a large volume of flowing air, which can be about 70 m ³ / h, can be achieved despite the very narrow and inconspicuous design of the guide profile inserts in the slot outlet. and can be silently discharged through a 1 m slit outlet which is fitted with guiding profile inserts. In the case of a double-sided version of a slot outlet with, for example, three slots, the amount of air supplied to the room up to the order of 420 m ³ / hour can be achieved over a length of one meter.

Another significant advantage of the slot-shaped drain according to the invention is that the air flow can be guided directly along the ceiling by means of guiding profile inserts, thus eliminating air access from the space to this ceiling, which has hitherto led to severe spotting of the ceiling.

The peculiarity of the slotted drain solution according to the invention can be seen in particular in the fact that the heat generated by the illumination tubes is dissipated, which can be combined with the supply of cold air through the guiding profile inserts. This special design on the one hand provides space cooling and fresh air supply to the room and, on the other hand, when the space is heated, warm air can be introduced into the space when the slot opening is closed, so heating is also supported.

In another preferred embodiment of the slotted drain according to the invention, the edge profile is provided with a separate covering frame, which may be square, rounded and the like, and which gives the slotted drain a certain aesthetic appearance.

Another advantageous embodiment consists in that the shaft is provided with a cover, which is fixed to the ceiling, with the outlet opening opposite to the cover being delimited by the bottom. A slot outlet is inserted in the shaft outlet or in the bottom.

The guiding profile insert deflects the discharged air stream by turning or turning it clockwise, left or straight down, with a plurality of guiding profile inserts attached between two edge profiles and possibly at least one web in a row and / or adjacent to each other.

The entire structure of the lighting device can be placed on the ceiling or recessed into the ceiling. The construction is particularly suitable for installation in double ceilings or other profiles.

In order to achieve the integrity of the ceiling, an embodiment in which a lamella frame is provided between the mounting angles of the side walls of the casing, which gives the casing a certain appearance, provides special light guidance from the casing and promotes the integration of the slotted drain in the ceiling.

DETAILED DESCRIPTION OF THE INVENTION

According to FIG. 1, the slot outlet R consists of an approximately rectangular housing 1, in the bottom of which the outlet opening 3 is formed. On both sides of the outlet opening 3, channel walls 4,5 are formed on the bottom 2. FIG.

Inside the housing 1 there is provided an insert 6 in which openings 2 are formed for the air flow (not shown).

For the sake of uniformity of this air flow, the apertures 7 are preferably arranged to the left and right of the outlet aperture.

Advantageously shaped edge profiles 8a, 8b are pushed onto the individual channel walls 4, 5. These edge profiles 8a. 8b may be of plastic or aluminum, for example. In the illustrated embodiment, each of the edge profiles 8a, 8b is provided with a plate 9 from which the clamping strip 10 is bent. This clamping strip 10 surrounds the channel wall 4, 5 in the working position, thereby fixing the edge profile 8a, 8b to the channel wall 4. , 5.

The plate 9 is joined by a carrier strip 11 forming a stop 32. The support strip 11 has an uneven thickness due to the accumulation of material. This accumulation of material may, in some sense, constitute a snap-in elevation 12.

Individual guide profiles 13 are mounted on the individual carrier strips 11. 14. The first guide profile 13 consists essentially of a guide strip 15, which is preferably provided with a depression 16 which corresponds to a snap-in elevation 12a. A guide shoe 17 adjoins the guide strip 15, which narrows the cross-section 18 between the two edge profiles 8a, 8b.

The second guide profile 14 on the opposite side is provided with a convex camber 19, which is again provided with a depression 20 which corresponds to the snap-in elevation 12b. For convex arching

- 11 19 is followed by strap 21.

In the illustrated embodiment, an air guide strip 23 of known construction is arranged between the strip 21 and the guide strip 15 in the exhaust port 22.

In the exemplary embodiment of the slotted drain RI of FIG. 2, the housing 1, the channel walls 4,5a, the edge profiles 8a, 8 ' are designed as in FIG. 1. The guide profiles 13, 14, however, are provided on respective support strips 11a. 11b, so that the guide foot 17 with the convex camber 19 defines a rightwardly directed exhaust opening 22a. which is also indicated by arrows 24a. The air stream 24 in FIG. 1, on the other hand, projects vertically downward.

In order to achieve the air outlet to the left, it is sufficient to swap the guide profiles 13, 14 of FIG.

It is preferred that the guide profiles 13, 14 and optionally the air guide strip 23 form an integral part of the guide profile insert 25 of FIG. 10 which can be inserted between the carrier strips 11a. 11b. These carrier strips 11a. 11b avoids the insertion of the guide profile insert 25, so that the respective snap-in elevations 12a. 12b may fit into the respective recesses 16, 20. In this case, the guide profiles 13, 14 are then connected to each other by respective end walls 26, connecting bridges or the like.

It can be seen from FIGS. 3 to 5 that a plurality of guiding profile inserts 25 can be arranged parallel to one another in order to achieve the required slot outlet width for each of the guiding profile inserts 25. a spacer sleeve is inserted between the edge profiles 8a, 8b. 27. wherein the edge profiles 8a, 8b are connected to each other by means of fastening elements 28 which pass through the spacer sleeves 27. The fastening elements 28 and 8a, 8b, 8b, 8b, 8b, 8b, 8b, 8b, 8b and 8b are connected to each other by means of fastening elements 28.

the spacer sleeves 27 are preferably arranged such that they do not lie flush with the guide profile insert 25 so that they do not affect the outgoing air stream 24.

Referring to FIG. 4, the slotted drain R3 is divided by at least one bridge 31 which is secured between the edge profiles 8a, 8b by means of spacers 27 and fasteners 28 so that at least two guide profile inserts 25 can be inserted side by side.

The bridge 31 is provided with grooves 30a on its lower profile 38 on both sides. The upper end 40 of the upper thicker profile 39 is preferably rounded to prevent swirling around the flowing air.

In the exemplary embodiment of FIG. 4, the right guiding profile insert 25 is inserted such that the outgoing air stream 24 is oriented approximately directly downward. The left guiding profile insert 25, on the other hand, is mounted such that the air flow 24 is deflected to the left.

In the slotted drain R4 according to the invention of FIG. 5, two webs 31 are fastened between the edge profiles 8a, 8b by means of spacers 27 and fasteners 28 so as to form a slotted drain R4 with three differently oriented guide profile inserts 25 side by side. The right guide profile insert 25 directs the air stream 24 to the right, the central guide profile insert 25 directs the air stream 24 directly down, and the left guide profile insert 25 directs the air stream 24 to the left. Thus, the air outlet from the slot outlet R4 can be adjusted differently by the guide profile inserts 25, in that the guide profile inserts 25 are simply removed and rotated or reversed. The air stream 24 can thus be directed either to the right or left or down. This is done by turning the guide profile insert

13 25 around its longitudinal axis, optionally by rotation about a central axis, which is perpendicular to the air guide plates. The slot drain R5 of FIG. 6 is provided with a cover frame 33 which, outside the edge profiles 8a, 8b, is connected to these edge profiles 8a, 8b by means of fasteners 34. The cover frame 33 allows a particularly aesthetic installation of the slotted drain R5 in the ceiling or wall. The cover frame 33 can consist of outer profiles 41 of different shapes and designs. Thus, the cover frame 33 may be bent, rounded, angular or the like.

Figures 7 to 9 show preferred embodiments of the slotted outlets R6 according to the invention, from which various air directional options are evident. According to Fig. 7, the air flow is directed downwardly through the guide profile insert 25, while in Fig. 8 the air flow is directed to the left and in Fig. 9 the air flows to the right. The air flow is indicated in Figures 7 to 9 by the arrows L _{1 (} L ₂ and L ₃ .

In this preferred embodiment of the slot-shaped drain R6 according to the invention, it is also intended to be connected to the edge profiles 8a. 8b could be riveted, glued or also detachably attached to the cover frame 33.

Fig. 9 shows a slot outlet R6. in which air can enter the housing 1 directly from the inlet nozzle 36, which is fixed to the side wall 37 of the housing 1. Through this insert 6 and the guide profile insert 25, this air in this case flows out to the right.

In the guide profile insert 25 according to FIG. 10, springs 29 are arranged laterally in its side wall 42, which, when the guide profile insert 25 is inserted, engage in corresponding continuously extending grooves 30 of the edge profiles 8a. 8b. Thus, the guide profile insert 25 is detachably fixed between the edge profiles 8a, 8b.

The individual springs 29 are arranged in the middle of the height of the guide profile bushing 25, so that even when the guide profile bushing 25 is rotated or reversed, the springs 29 are at the same height and thus locked into the grooves 30a. 30b. The corresponding stiffness of the guide profiles 13, 14, the guide feet and the air guide plates 23¾ is provided by the end walls 26 of the guide profile insert 25.

Fig. 11 shows a slotted drain R7 in which it can be clearly seen that between the edge profile 8a and the bridge 31, or between several webs 31 and / or between the bridge 31 and the opposite edge profile 8b, it can be one behind and / or side by side a plurality of guide profile inserts 25, also with different lengths, are snapped into place. A cover frame 35, 36 is also mounted around the edge profiles 8a, 8b.

It is also contemplated in the slotted-outlet design of the present invention that by means of a suitable cover (not shown), it is possible to form various combinations with the slotted-outlets so as to limit or vary the air flow and also to introduce air into different areas of the space. different amounts and different directions. It is also within the scope of the invention to design the guide profiles 13, 14 of the guide profile insert 25, which can also be glued or otherwise attached or shaped to the carrier strips 11, for example.

The slot outlet B in combination with the illuminating body consists of the housing 51 in FIG. 12, in whose bottom wall 52 the slot openings 53 are formed which can be closed or opened by a slot slide 54, which is slidably supported on both sides in supporting rails. 55.

On the bottom wall 52, apart from the slotted openings 53 on the beams 57, preferably two lighting tubes 56 are arranged.

On the opposite side of the bottom wall 52, a spout 87 is fastened over the width and length of the slotted openings 53. In addition to this spout 87, the support angles 59 are further connected to the bottom wall 52.

From the bottom wall 152, side walls 61 are formed which form their mounting angles 62 with their further curved edges. The individual mounting angles 62 and support angles 59 are connected to a shaft 63 whose inner side wall 64b is connected to the housing 51.

An opening 66 is formed in the outer side wall 64a of the shaft 63 into which the inlet nozzle 86 opens. The shaft 63 is further secured to the ceiling 67 by means of a cover 65.

Slotted outlets A, whose edge profiles 8 are provided on both sides with clamping strips 10, which support the outer side wall 64a and the inner side wall 64b of the shaft 63, are disposed in the discharge opening 68 which is opposite the cover 65. 13. Each slot outlet A is provided with a plurality of guiding profile inserts 25, in which the air outlet can be adjusted in the direction of the arrows L1, L2, L3 by rotating and inverting them. that is, right, left, and vertically down.
