Utility model application

Photographic camera

The innovation relates to a photographic camera with a device for flash lamps with detonators and a two-slide shutter, the opening member of which initiates an exposure and the closing member to follow Provision of an electronic measuring and control circuit by means of a magnet for the process and thus for Completion of the exposure is released.

Cameras with closures of the type mentioned above are for example from the German patent specification 1 196'494 and the German Auslegeschrift 1 211 933 known, according to which the lock is designed as a central lock. According to the German Auslegeschrift 1 26o 97o possesses the camera has a slide lock of the same type.

According to the French patent specification ι 546 42ß is also a photographic camera with flashlight device for percussion flashlights is already known. The Pressing the camera shutter from a notch in its push rod, the adjacent arm of a two-armed Swivel lever so long taken until by the other lever arm attacking the firing pin for the lightning strike the firing pin spring is tensioned and the push rod, which also triggers the camera shutter, meets an inclined surface deflecting it, whereupon the pivot lever is released, and the now spring-driven Firing pin ignites the flashlight. The arrangement has the major disadvantage that the triggering with a force storage is charged by at his Actuation the firing pin spring must be tensioned for the flash ignition. Here you can see shaky images

difficult to avoid. In addition, this construction requires the flash device on the camera side a separate energy source for the ignition is assigned, additional effort to the necessary Always ensure synchronism between the flash lamp ignition and the shutter sequence.

The task of the innovation is to avoid such defects and to ensure that a camera works reliably cited genus to ensure in a simple manner even with flash photography. It is further demanded that a driving member actuates both the shutter and the trigger mechanism for the percussion fuse. Furthermore, the trigger mechanism for the impact ignition should only be inserted in the flash lamp unit the version provided by the camera must be functional.

These tasks are performed in the case of a photographic camera with a device for flash lamps with percussion detonators and a two-slide shutter, the opening member of which initiates an exposure and the closing member of which as required an electronic measuring and control circuit by means of a magnet for the process and thus for termination the exposure is released, according to the innovation

solved that a sling lever is provided for driving the opening member, which is in the film transport phase is cocked and when released by actuating the trigger, the percussion ignition device is also actuated and that both locking elements are connected to one another by means of a tension spring which, when the locking mechanism is opened, So when the opening member is moved into its open position, tensioned and after releasing the Closing member by the attraction magnet drives this until it has assumed its closed position.

It is thereby achieved that the tension spring connecting the links in the rest state of the closure, in its End position after expiry and during the film transport phase is inoperative and relaxed.

The details and further features of the innovation emerge from the following description of two Embodiments and the claims.

The drawings show schematic representations of the parts necessary for understanding. For a better overview if all other parts are omitted, so is the percussion ignition device in the illustration of the second Embodiment.

The drawing shows in

Fip. 1 a two-slide lock in trigger ready

Position with attached percussion fuse die;

2 shows the same arrangement after triggering with the shutter now open and the Schiagündme chani smus actuated;

3 shows the same arrangement after the closing element has been released by the attraction magnet and the exposure has been completed;

4 shows another exemplary embodiment of the lock in the position ready for release;

5 shows this arrangement at the moment of exposure;

6 shows the same arrangement after the completion of the exposure.

In Fig. 1, the first embodiment is ready to release Position shown. The exposure opening 1 is covered by the opening member 2 in a light-tight manner. at Triggering is the opening member 2 under the action of the fork-shaped engaging sling lever 3, which during the film transport phase was tensioned against the force of its drive spring, not shown, in the direction of the Arrow A. The exposure aperture 1 is cleared

given. In addition, the slope 3a hits against the pin 5a of the ignition slide 5, which is thereby raised in the direction of arrow B to such an extent that the percussion ignition device of the lightning cube 4 is triggered. This shows Pig. 2. If there is no lightning cube 4 in the fitting 17, the ignition slide 5 remains under the action of the spring 16 in a position outside the bevel 5 a, because the pin 18 in the fitting 17 is not pressed. For this reason, the igniter 5 via the sprung lever 19 is connected to the pin 5b of the igniter 5 and the pin l8 \ n the PaDSung 17 cooperates, in a non-illustrated inactive position. When the rocker arm 3 ^J n expires in the position shown in FIG. 2, a tension spring 7, which is suspended between the two locking members, is tensioned. The closing element Io is held on its nose lob by a hook on the armature 9 of the attraction magnet 8. This armature 9 is mounted in the pivot point 15 and is held in the position shown in FIGS. 1 and 2 by the spring 14.

The end of the exposure time is determined by an electronic exposure time formation device and the attraction magnet 8 switched on. The armature 9 is attracted in the direction of arrow C by the attraction magnet. Through this

the locking of the locking member Io is released so that it also runs in the direction of arrow A following the train of the tension spring 7 until it rests on the bolt loa. In order to If, as FIG. 3 shows, the exposure opening is closed again, and the exposure is ended.

During the film transport and spam process, the sling lever becomes 3 and the closure gleather 2 and Io into the in Fig. 1 returned position. Air. Eolzen loa the opening member 2 is in contact and push it Closing member Io opposite to the direction of the arrow A bis to the engagement of the hook on the armature 9 »which has since fallen from the currentless magnet δ, with the Nose praise of the closing link Io.

The second embodiment seigt in Figures 4 _r 5 and 6 a first embodiment enfcsr - ·· - sponding sequence. The repeating components are given the same numbering.

The sling lever 3 pushes the opening member 2 through Frictional connection on the nose 2a in front of you until it briefly on the housing-fixed ramp 1 ° in the direction of the arrow D is raised. The opening member 2 is held by the retaining pawl 13 in the open position according to FIG. 2 held.

A tension spring 11 is tensioned during this first phase of the closure sequence. It is used for repatriation both closure members 2 and lo, as Fig. 6 shows. here the closing element has followed Io and its bolt loa meets not only the edge of the opening member 2 but also the arm 13b of the retaining pawl 15, so that the engagement occurs the pawl 13a is canceled. Now both locking links can 2 and Io run back together under the action of the tension spring 11, which is attached to a point 2c fixed to the housing. The closing element hits Io against an arm 9a of the armature lever 9 and forces that Latch on the nose lob. At the same time, the armature 9 of the yoke of the attraction magnet is against possibly still effective remanence tapped.

The second embodiment thus shows a solution with automatic return of the closure members 2 and Io in their initial position, as shown in FIG. The tensioning process of the sling lever 3 remains unencumbered by this function.
