DE1960843C - Photographic camera with flash device for percussion lamps - Google Patents

Description

The invention relates to a lens shutter photographic camera, in particular Spin lock, and a flashlight device for flashlights with detonators, which after success Impact ignition is brought into the ready position.

A flashlight device for flashlights with percussion detonators on or in a photographic camera can be found in French patent specification 1,546,428. The solution disclosed herein provides that when the camera shutter is pressed down from a notch in its push rod, the adjacent one Arm of a two-armed lever is carried along until the other arm, which is on the Firing pin for the lightning strike is present, dic The firing pin spring is tensioned and the push rod, which also triggers the camera shutter, encounters an inclined surface that deflects it. This finally releases the lever, and the spring-driven firing pin ignites the flashlight. The arrangement has the essential

xo disadvantage that the triggering with a power spoke tion is burdened by the fact that when it is actuated the · .. · Firing pin spring for the lightning ignition must be spamu. Here, shaky Au! difficult to avoid. In addition, sit lets:

the lock actuation described here not fl use a spin lock actuation, without the risk of ending uneven shutter speeds

len.
Another flashlight device for use

ao ding of blown flashlights is by d, German patent 1 961 558 has become known in which a pretensioned percussion fuse the flashlight triggering ignition slide is provided, which is de *.

»5 centrifuge lock in its cocked position th is, when releasing the striking link to drive the shutter for percussion ignition Auslosunu is released and returned to its tensioned position towards the end of the Schlag memberbe movement

will. The spring driving the striker must be made quite strong in addition to de; Actuation of the lock still resets the ignition slide. This results There are undesirably loud locking noises and the spring cannot respond to the requirements of the lock be voted alone.

The present invention was therefore based on the object that the closure sequence evenly and unencumbered and thus unaffected by other processes necessary for a flash exposure should be. But that means that the force of the running impact member for the drive of the Centrifugal lock must only be available. In addition, the disadvantages mentioned or defects are avoided.

The solution to the problem is contained in the claims and is based on the drawings explained. The same parts in the various exemplary embodiments are given the same reference symbols Mistake. It shows

F i g. 1 is a perspective view of the shutter drive and ignition device with a spring-loaded locking member for the ignition slide,

F i g. 2 shows a section from a similar device, but with a spring-unloaded locking element, that has a sprung arm.

If, as in FIG. 1 shows that a flash cube 1 is inserted into the socket (not shown), its base 2 actuates a transmission pin 3 and this actuates the pawl 4 in the direction of arrow A so that its nose 4a unlocks the ignition device 9 at the angled portion 9a. During film transport, the pawl 13 is moved against the force of its spring 19 by means of the slide 14 in the direction of the arrow C into the extended clamping position and is secured by the holding pawl 12. Simultaneously, by the projection 14a via the bend 6 b the jar member 6 and thus the holding pawl 8
