Abstract

The air outlet, for fitting to the air flow channel in a ventilation system, has a mantle (1) with openings (3) and at least one diaphragm ring (4,5). A part of the mantle has a shrouding cover (23), around one side of its axis. An adjustment cap (6) is within the mantle, with a stub shaft (7) operated by a rotating lever (15).

Description

The present invention relates to a Air outlet for connection to an air duct system with a jacket which has recesses and in which at least one aperture ring is arranged, wherein a part of the Sheath is provided with a cover.

Such air outlets are already in many forms and execution known. Thus, DE 34 29 710 and DE DE 39 18 218 each have an air outlet, in which Air enters through an air inlet and through Perforations in a coat re-emerges. In the event of a desired cooling effect, the air is through a blind ring or multiple blind rings upwards distracted. In the case of a desired heating effect, the Air through the glare ring or the multiple glare rings deflected diagonally downwards.

The disadvantage with these devices, however, is that that it is with the supply of cold air for the cooling case despite the distraction of the air by one or more Blendringe can come to drafts. It is at the known devices not possible, the air flow so to set a person shielded from the supply air if she wants that.

Another air outlet is described in DE 35 21 661 A1 described, which consists of a circular curved Perforated metal jacket exists, the perforated metal jacket at four closed by blind fields is. The holes of the perforated sheet metal jacket can by means of four be covered by vertical strips, the four Strips are connected across a vertical shaft and over a servomotor can be rotated. A mobile one Stauring inside the perforated metal jacket is also intended.

The disadvantage of this air outlet, however, is that it also not possible, the air supply in one Set room so that only a certain area of the Room is supplied with supply air and / or another Area not.

Object of the present invention is the above known air outlets to improve that a finer adjustment of the air supply is possible.

To solve this problem leads that an adjustment flap is provided inside the shell, which above the Cover is arranged.

This cover ensures that the air passes through the covered part can not penetrate, but escapes sideways. A person, therefore, before the Cover stops, gets only indirectly from air, and indeed through the recesses of the mantle, not through the Cover are hidden.

Since the cover be arranged adjustably on the jacket can, she can from a person completely according to desire be set.

The size of such a cover can continue to be chosen For example, they only cover part of the mantle covering or only a part of the coat on the one hand his axis.

Furthermore, the air distribution through the design of the Mantels in connection with the cover continues to be influenced. So can the coat of different Sections exist, which are equal or large have different sized recesses. The coat but can also be a simple perforated metal jacket. Here is The invention has no limits.

The air supply can be supplemented by one or more optionally rotatable and / or displaceable glare rings be distracted, which are arranged inside the mantle are. Again, the shape and the arrangement of the Glare rings set no limits.

A better distribution of air is through the Adjustment flap reaches inside the jacket is arranged above the cover. These Adjustment flap can be adjusted rotatably by means of a rotary lever.

Instead of the rotary lever can also be a cable adjustment be provided, by means of which the adjustment flap rotated becomes. Further corresponding devices are conceivable.

If the adjustment flap is in a vertical position, then the air can flow freely past and after exit below. However, if the adjustment flap is in horizontal position, so is in front of the adjustment flap Air accumulation is generated and the air flows in horizontal Direction outwards or even diagonally upwards away.

Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawing; this shows in

Figure 1 is a partially broken away side view of an air outlet according to the present invention;

Figure 2 is a perspective plan view of the air outlet according to Figure 1 with horizontal adjustment flap; and

Figure 3 is a perspective plan view of the air outlet according to Figure 1 with vertical adjustment flap.

According to FIG. 1, an air outlet P has a jacket 1, which has a region 2, with recesses. 3 is provided.

Inside the shell 1 are two blind rings 4 and 5 arranged, which optionally rotatable and / or displaceable are.

Furthermore, inside the jacket 1 is a Adjusting flap 6 is arranged, which via a Stub shaft 7 is connected to a rotating device 8.

This rotating device 8 has at its lower end Joint 9, via which a linkage 10 with a lever eleventh connected is. At the other end of the joint 9 is the lever 11th with a bolt 12 in a curved slot 13th guided. This slot 13 determines the rotation of the Stub shaft 7 and thus the adjustment flap. 6

The stub shaft 7 and the slot 13 are both in one Holder 14 is provided, which is arranged on the jacket 1 is.

At its upper end, the rotating device 8 a Rotary lever 15, which via another joint 16 with the upper end of the linkage 10 is connected. Of the Rotary lever 15 is at its one end with a knob 17th provided, which better handling of the rotary lever 15th allows.

With its other end, the rotary lever 15 is in one Sleeve 18 which is mounted on a turntable 18. This hub 19 rotates about an axis 20 on a Holder 21, which in turn by means of fasteners 22 is mounted on the jacket 1.

Furthermore, on the jacket 1 of the air outlet P a Cover 23 is arranged, which extends below the Adjustment flap 6 is located and by means of fastening elements 24 is attached to the jacket 1.

In Figs. 2 and 3, the interior of the air outlet P is to see, with the adjustment flap 6 in different Positions is shown.

Inside, the two rings 4 and 5 are over Fastening elements 25 and 26 rotatably mounted, wherein Stops 27 and 28 are provided which the desired Determine the end position of the blind rings 4 and 5.

The adjustment flap 6 is above the stub shaft 7 and a further stub shaft 29 also rotatably mounted, wherein a stop 30 is provided, which is an end position of the Adjustment flap 6 determined.

In Figure 3 is further by the position of the adjustment flap 6 the outside fitting cover 23 through the recesses 3 to see.

The operation of the present invention is as follows:

By a not shown in detail air supply system is Air in the jacket 1 of the air outlet P out, in which they through the different arrangements is distracted. So the air in the mantle 1 hits the first aperture ring 4, whereby before the aperture ring 4 a Air accumulation arises. This part of the air is already before the blind ring 4 led to the outside, the other part of the Air passes through the glare ring 4.

A short time later, the remaining part of the air hits the second aperture ring 5, which again an air storage arises. Consequently, some of the air enters before the Blendring 5 to the outside, the remaining part passes through the aperture ring 5 further down.

Then the rest of the air hits the Adjustment flap 6. Depending on their position, the air can now completely through the recesses 3 of the shell. 1 escape or through the remaining coat 1 down go and escape from there into the room.

The former is achieved when the rotary lever 15 down is rotated and the adjustment flap 6 is therefore closed is. The air then occurs evenly on all sides horizontally, diagonally downwards or diagonally upwards.

However, when the rotary lever 15 is turned up, is the adjustment flap 6 in an open Position and the air can go past her in the down Room escape, wherein the cover 23 an outflow of the Air in a certain direction prevented.
