An air guide element 16 is flexibly mounted out both gratings 11, 12 at each crossing points of the grating bar 13, and each air guide element 16 has four flat air guide blades 21, and these air guide blades extend along a longitudinal axis 20 of the air guide element 16 protruding radially from the longitudinal axis 20.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention comprises two plates that are movable in parallel to each other in an IKIM and allow air to pass therethrough, and a plate that extends between these two plates and connects them. The present invention relates to an air outlet nozzle, in particular for a ventilation system of a vehicle, having a plurality of mutually parallel air guiding elements which are held in motion.

[Conventional technology]

In a known air outlet nozzle of this type (DE 32 02 355), both plates in parallel planes have apertures, between each aperture in the front plate and the rear template. , an air guide element in the form of a capillary is provided and is supported for free movement on both sides. The rear wall plate is movable parallel to the front plate. Each capillary is divided into four parallel air guide holes by a Va wall. By moving the rear wall plate, the orientation of the parallel tubes and thus the air outflow direction is adjusted. Although this known air outlet nozzle has a compact design, it has the disadvantage that, over the entire area of the mutually movable plates, only a comparative cross-section is available for the actual air guidance. Furthermore, the manufacture of this air outlet nozzle becomes quite complex.

[The conspiracy that invention attempts to solve]

The problem on which the invention is based is, in the first type of air outlet nozzle, to increase each portion of the curved area used for air guidance out of the total area used by the air outlet nozzle, Sky 9. is to increase outflow.

[Means for resolving conspiracy]

In order to solve this problem in the air outlet nozzle of the first type mentioned above, according to the present invention, the plate is configured as a grid having grid bars that are narrower than the width of the grid mesh, and each air guide element has a common The air guide vanes are formed by at least two thin, flat air guide vanes extending along and projecting from the longitudinal axis and flexibly attached to each grid at opposite ends of the longitudinal axis.

〔Effect of the invention〕

Due to the inventive configuration of the air guide element, the air guide element only requires a comparative image, so that a large flow cross section remains and the reduction of this cross section due to a change in direction is limited to a minimum. Adjustment of the air guide vanes and thus change of direction of the air can be effected by movement of the rear or front grid.

The air outlet nozzle according to the invention is inexpensive to manufacture and the shape requirements and installation are easily adapted to the spatial design.

Advantageous developments and configurations of the air outlet nozzle according to the invention emerge from the further claims.

〔Example〕

The invention will be explained below with reference to the embodiments shown in the drawings.

The air outlet nozzle for a motor vehicle ventilation system, shown in longitudinal section in FIG. 1 and in perspective in FIG. The board is made of thin plastic lattice rods 1 that extend across each other.
It is configured as a grid 11, 12 with large grid meshes having 3 meshes.

The grid bars 13 are bulged inwardly on opposite sides of both grids I+, 12, so that the intersection point 17 of the grid bars 13 is at the highest elevation of the bulge. At each intersection 17, a ball socket +4a of the ball joint 14 consisting of a ball socket 14a and a ball 14b is formed. For example, use it as a measuring board.
Both gratings 11.12 are constructed identically, except that the previous grating 11 is mounted on a rectangular frame 15 that can be moved. The ball 14b of the ball joint 14, which is held in the mouth 14a, is provided on the end face of the air guide element 16 and is preferably formed therein. The air guide element 16 therefore has both %Ji's, 12 at each intersection point 17 of the grid n13.
flexibly attached to each of the An operating pin 19 passing through a specially formed support 18 in the front grid 11 is fixedly attached to one of the air guiding elements 16, its longitudinal axis being aligned with the longitudinal axis 20 of the air guiding element 16 -J They are becoming poorer. When the operating bin 19 is swung in one direction, the rear grating 12 is moved parallel to the front grating 11 via the air guiding element 16 connected thereto, and the parallel air guiding element 16 changes its position, and the air flowing through the air outlet nozzle from the rear grate 12 to the front grate 11 changes its outflow direction in accordance with the changed position of the air guiding element 16.

In particular, as shown in Figure 2, it is made from plastic. Each air guiding element 16 has four nicely flat air guiding vanes 21, which air guiding elements 1
6 and projects radially from this longitudinal axis 20.

The four air guide vanes 21 are each oriented toward one another by the same angle of 90°. The air guide vanes 21 of the adjacent air guide elements 16 form air guide holes 22 with a rectangular cross section and a large air passage surface.

As shown in Fig. 2, a rubber joint 23 is used instead of a ball joint.
It can be provided between the intersection point 17 of the grid 11.12 and the end face of the air guiding element 16.

Another embodiment of the air outlet nozzle is shown in FIG. Grids 111 and 112 are formed flat and have protrusions 130 at intersections 117 of straight grid bars 113. These projections 130 are provided inside the grids 111 and 112, so that the projections 130 of both grids I11, 112 face each other. Each protrusion 130 is formed with a port 14a of the ball joint 14, and the ball 14b of the ball joint 14 is connected to the air guiding element 16 configured in the same manner as in FIGS. is maintained within the range.

The rear grid 112 is fixedly mounted, for example, on the vehicle's ttia panel, and the front grid 111 is movable in the guide 131 in the orthogonal direction. Thus, the front grating 111 in FIG. 3 can be moved perpendicularly to the plane of the figure and from side to side. Depending on the relative position of the front grid 111 and the rear grid 112, the parallel air guide elements 116 are reoriented to give the air exiting the front grid 111 a desired outflow direction.

FIG. 4 shows a part of the air outlet nozzle in a perspective view, looking in the direction of arrow IV in FIG.

However, the air guide element +16 has here been modified with respect to FIG. The air guide element has only two thin flat air guide vanes 121 which likewise extend along a common longitudinal axis 20 and project radially from it. Both air guide vanes 121 form an angle of less than 90°. Furthermore, the ball joint 14 of FIG. 3 on the end face of the air guide element 116 has been replaced by a rubber joint 123. The previous grid 111, which is identical to the previous one, is shown only schematically in FIG. 4 for clarity.

FIG. 5 shows in a perspective view the air outlet nozzle of FIG. 3 integrated into the instrument panel of a passenger motor vehicle. An operating knob +32 is attached to the front surface of the movable front grid 111. This knob 132 allows the grating 111 to be moved up and down and left and right in the orthogonal direction, as shown by the crossed arrows in the 5th rXJ. Air guiding element 116 thereby
changes its direction, thereby changing the exit direction of the air flowing through the air outlet nozzle. FIG. 5 clearly shows the flexibility of the air outlet nozzle in terms of adaptation and configuration to the vehicle design.

6 to 1O, the air guide element 216 or 3
Some embodiments of 16 or 416 configurations and arrangements are shown. In FIGS. 6, 7 and 8, each air guiding element 216 has two thin air guiding vanes 221, these air guiding vanes having a vertical axis! 120 and are therefore arranged 180° apart from each other.

In FIGS. 6 and 7, the air guide elements 216 are arranged such that the air guide vanes 221 of adjacent air guide elements 216 define air guide holes 222 of square cross section therebetween. In FIG. 8, the air guiding elements 216 are arranged such that the air guiding holes 222 have a triangular cross section.

The air guiding element 316 in FIG. 9 similarly has only two thin, flat air guiding vanes 321, which are offset from each other by 90°, whereas the air guiding element 416 in FIG. having two air guide vanes 421,
These air guide vanes are offset from each other by the same angle, ie 120°. The air guide vanes 421 of the adjacent air guide elements 416 are here provided with air guide holes 422 of hexagonal cross section.
