"Device for aligning τοη elements" ines optical system ".

The .Erfindung relates to a device for

mutual alignment of two or more elements of an optical system containing a light source, such as the alignment of this light source with respect to an eeflector cooperating with it, wherein at least one of these elements old his holder on a carrier attached and along the contact surface of the holder and carrier is movable.

Such gate directions are 2.B, with headlights and projection apparatus used. A well-known projection machine is provided with a device, the holder of which is in the form of a slide, which is displaceable along the carrier. The holder contains a light source and the carrier is generally the housing of the projection apparatus attached.

By moving the holder, the oil body of the light source can be aligned with the reflector, which is also located in the housing. It is shifted by means of a device that is incorporated into the carrier Screw bolt. This device has the disadvantage that the alignment can only take place in one direction, during sub alignment in a direction transverse to this direction, for example, a separate adjustment mechanism, e.g. again a balter and a carrier, is necessary

This difficulty can be countered by applying magnetic forces to the mutual fastening of the holder and the carrier be used. By suitably shaping the holder and carrier, at least in the vicinity of their contact surface, the possibility is created that the holder can be moved in all directions in this plane is movable. FDr an adjustment of the holder and the carrier in two dimensions you no longer need a cross slide system.

The invention aims to further improve such a device. For this purpose, a device has the aforementioned Type in which the holder is slidably attached to the carrier by means of one or more fastening magnets, according to the invention the feature on that the holder or its carrier in the vicinity of their contact surface a sexton of fastening magnets and / or easily magnetizable zones and / or poorly or non-magnetizable zones contain, wherein the patterns match ^ and the magnetic holder attachment in at least one position of the holder opposite the carrier is interrupted. This has the advantage that the holder can be moved with a single hand movement and after a certain movement of the holder relative to the Carrier can be removed from this without the device having to be completely or partially dismantled. This makes it easier to

An embodiment of the invention is in the drawings and is generally described below.

according to Fig. 1 lings the line II-II,

Fig. 3 shows a representation of τοπ five possibilities The way in which magnets, easy-to-tell zones or sole-less or non-predictable zones in a holder and a carrier do matching sextons can be arranged.

The device naoh FIGS. 1 and 2 contains a holder 1 and a carrier 2. In the holder 1 is old with the help of contact elements a projection lens 4 aufgenossetuln this example, the Laspe is a so-called Halogenlaspe sit only one pinch. The carrier 2 is rigidly attached to the projection apparatus, a small part of which is shown at 5. The suldenfSrsige reflector 6 is attached as carrier 2. The holder 1 contains, in the example shown, three permanent magnets 7, by means of which the holder as carrier 2 is slidably attached. With this type of fastening, a displacement of the holder 1 with respect to the carrier 2 is even possible in all views in its contact surface XX. The magnets 7 are arranged in a ring-shaped pattern in intermediate ruffles. They lie in a position of the holder at which this seat of the carrier is connected, opposite the easily magnetizable parts 8 of the carrier 2 the parts 9 act as poorly magnetizable carrier ions. In the example shown, this has been achieved in that the parts 9 are designed as sulphurous depressions in the plate-shaped carrier 2.

The holder 1 can except for straight movements, thanks the described shape of the circular pattern of the holder 1 and. of the carrier 2, also feel rotational movements with respect to the carrier. Venn this rotating movement is continued so far that the magnet 7 the

Depressions 9 to lie opposite comaen, the magnetic holder » fastening interrupted or less firm. The holder can then easily be removed from the carrier.

The displacement of the holder 1 with its lamp 4 relative to the carrier 2 with its reflector 6 can bti the device shown can be easily regulated and a holder position once reached can be made parallel to the contact surface with the help of the three arranged in carrier 2 X-X effective screw bolts that press towards the center of the ring nut 10 can be fixed.

The contact elements 3 are on one in FIGS. 1 and 2 In a manner not shown in more detail, fastened in the body 11 slidably received in the holder 1. The displacement of the body 11 takes place by operating the screw bolt 12 located in the holder 1. The holder 1 and the body 11 are cylindrical. The body is secured against rotation by a pin 14 reaching into the slot 13, which is fastened in the holder 1.

The device shown in FIGS. 1 and 2 is only one example of the many possible embodiments of such a device According to the invention, the magnets can of course also be designed as electromagnets. The device can by adding a holder and / or carrier attachment that works according to the already described magnetic attachment can be expanded, which allows displacements in the form of rectilinear and / or rotating movements in another plane. For example, the one according to Fig. 1 with learning holding body 11 possible adjustment achieved by an adjustment with the help of a magnetic fastening device near the

It should also make sense that a magnetic one Attachment of a holder to a carrier genäse the invention with different Patterns of the magnets present in this holder and this carrier and / or easily magnetizable zones and / or poorly or non-magnetizable zones is feasible. Figure 3 shows five Examples of such training. In the Pig example. 3a is only one of the by a holder and a carrier, as with 15 and 16 labeled, formed elements provided with magnets. This is element 15} the magnets are marked M.

Between these zones in 16 lie the poorly or non-magnetizable ones Zones C. In practice, FIG. 3a is a schematic representation of the embodiment of the invention shown in FIGS. 1 and 2 Contraption.

3b to 3e are all schematic representations of patterns in which magnets I5 and 16 are present in both elements are. In Fig. 3b these magnets only wake up bit well-magnetizable zones and the magnetic attachment is through cooperation of a magnet with such a zone. If the element 15 is displaced with respect to the element 16 over such a distance,
