Photographic camera with a socket for flash lamp holder

The invention relates to a photographic camera with a mount of a cube-shaped flash lamp holder, behind each of its side surfaces a flashlight ignitable by impact is arranged, each A spring held in a tensioned position by a stop is associated with the flashlamp "which is held by the camera-side Means for generating an ignition shock can be released.

Compared to known cameras of this kind with the invention that when the camera is released no blow against the spring and therefore no force has to be used

To solve this problem it is proposed according to the invention, daft dl Spring through "In bei <" r Filmtransport- and / or Spaxrabew "gumg mad at «4er moving after the Kaaeraauiilösung

The link can be lifted from the stop and secured against relaxation by the link and released when the camera is triggered. However, it could also be arranged in the drainage path, for example, of a cam of a locking clamping shaft or of a locking drive element of a clamping lock. It is possible; that the member and the slide are mutually movable, preferably positively connected, _o

According to a special embodiment according to the invention, it is provided that the member is a spring action is a standing lever, the oblique fly lsi movement away a control surface of a double exposure lock and / or shutter drive slide is. Advantageously, the member comprises one against the Spring guidable unlocking surface and a retaining hook for the spring in the unlocked position, whereby the spring through the unlocking surface in the film transport or clamping movement can be lifted off the stop and can be fixed against relaxation by the retaining hook and when the camera and / or shutter is released Haltehakftn can be moved out of the spring's detachment path is.

üareii. the "rfindttnHBaause arrangement is the respective The mainspring located in the ignition position is already unlocked during the film transport and / or shutter tension, so that during the closing process no more blows have to be carried out against them, and then through the unlocking member held in the cocked position »when the lock expires or · camera actuation then moves the unlocking and holding member away from the holding position for the spring, so that the spring by an evasive movement of the link is released for ignition strike * This means that the force required to trigger the camera is considerable less »In addition, the force required to rotate the socket for the flash bulb holder is less, because the element influencing the ignition springs does not occur when the socket is rotated out of this or the Foot of the flash bulb holder must be pushed out.

The invention is described below with reference to an exemplary embodiment shown in FIGS. Show it:

According to Figo 1, 1 denotes a camera housing. A release slide 2 is arranged in the camera housing 1 and is under the action of a spring 3. An operating handle k engages on the upper end of the release slide 2. The release slide 2 has an arm 5 in the upper area, which comprises an inclined surface 6 o Furthermore, a film transport handle 7 is provided, which is designed as a rotary knob or switch lever and has a switching cam 8 and preferably two symmetrical switching cams 9 , which is under the action of a spring 12 and is mounted along a slot 13 to be rotatable and longitudinally displaceable about a pivot point Ik fixed to the camera »

The cocking slide 11 also has a shoulder 15 through which a locking opening in its frame position 16 closing closure sector 17 against the force of a spring 18 acting on it in a die Closure opening 16-releasing position pivotable is. The shutter sector 17 is fixed around a camera Pivot point 19 rotatable. The closure sector 17 also has in the region of the extension 15 of the cocking slide 11 a nose 20 on »

In the area of the film transport handle 7, the clamping slide 11 an angled approach 21, over which the cocking slide 11 after it has been triggered via a the switching cams 9 and 10 can be moved into its tensioned position shown in FIG.

The camera 1 has a socket for a cubic flash bulb holder 23, are provided behind the side faces each have a ignitable by impact flashlamp 2k together.? Flektor 25 »Each flash lamp 2k is designed as a tensioned wire 26 striking spring, which lies behind a pin 27, assigned If the wire 26 of a lamp 2k is lifted from the pin 27 by means of the camera and released, it strikes against the ignition element 28 of the assigned flash lamp Zk and ignites it.

Now, in the camera 1, a lever 30 is rotatably mounted around the pivot point 29. An inclined surface 31 of the same protrudes into the path of a curved surface 22 of the slide 11, which is bent or molded upward. Furthermore the lever 30 has an unlocking surface 32 for the springs 26 and a retaining hook 33 for the same.

The mode of operation of the camera is now as follows:

PF 7 ^ 6 / MF 1256

During film transport, the slide 11 is moved in the direction of the arrow 3k via a nook 9. Towards the end of this movement, the cam surface 22 meets the inclined surface 31 and lifts the lever 30 upwards. The unlocking flat 32 lifts the spring 26, which is currently in the ignition position, over the pin 27 ″ so that the spring 26 is unlocked, but is still prevented by the retaining hook 33 from executing an ignition strike. In this position the slide 11 is held by the release slide 2 «

If the trigger is now actuated, the slide moves against the direction of arrow 34. According to a conscience The lever 30 is drained away from the curved surface again 22 released and threatens to go down again. The spring 26 initially slides on the surface of the Holding hook 33 along and finally over this and carries out the ignition strike. Since the shutter actuation and the release of the spring 26 in a very specific, precisely defined time sequence when the slide is running 11, a good flash synchronization can be achieved without «achieving further»

By unlocking the ignition wire during film transport a striking link to be actuated during the locking process can be omitted

The moment the camera is released is reduced because no striker has to be actuated or released. aside from that the forces for the transport of the flash lamp holder, which can take place during film transport, are lower, because no striker from the opening for the spring 26 must be pushed out. Finally, notches for the functional positions of the flash cap carrier could be omitted, because this is aligned with the camera by the ignition wire 26 unlocked on the retaining hook.

Of course, a correspondingly acting lever can also be used in place of the slide 11 and in place of the lever 30 a corresponding slide step. Instead of the slide 11, a locking clamping shaft could also be used or any other link that moves in one direction when the film is advanced and in the opposite direction when the shutter is moved Direction is moved, find use. Finally, the members 11 and 30 could move relative to one another, z. B. positively connected to each other.
