The invention relates to a photographic camera with objective lenses, which has a switching element adjustable to several positions wxa switching on both an M, X flash light contact device and a built-in forward drive.

In the case of closures known per se, the setting positions of the switching element are designated "M", "X" and "V". Here, "λ" means a setting for a pre-ignition time of approx. 20 msec »" X "a setting for a pre-closing time" 0 ", ie for flashing when the full shutter opening is released, while with the setting ^N V ^N the feed mechanism is in the active position or is excited. In the settings mentioned, the switching element is secured in a manner known per se by notches arranged in or on the lock which can be overcome with a certain force. The pest control of the switching element achieved in this way, however, is not sufficient to exclude the risk of unintentional veratellena of the same. It can therefore happen, for example, that by manipulating the operator the switching element is mistakenly switched to one of the front and side settings that do not correspond to the type of flash used, which results in incorrect recordings.

Intentional adjustment of the shifting members also secure this in the way that a bolt which can be moved in the direction of the optical axis and which can be locked into fixed detent recesses is arranged on it. In particular, the actuating handle of the switching element itself can be designed as such a bolt ί, which cooperates with the Raatausnehmungen under the effect of its own springiness. The use of such a locking device is, however, difficult or impossible in various practical cases of need. This applies in particular when the Sohaltglied the Verachlußumfang not Overlooked and also just the Knapp Versehlußgehäuse outstanding Beüiätigungs- grabbed owns. In this case, there is no space in the axial direction necessary for attaching a special bolt. Likewise, with a short operating handle, the natural springiness of the material can only be used with difficulty or not at all, especially if the holding element is arranged between the levitation planes of other organs. erena of the switching element, which has an unfavorable effect both on the mobility of the switching element itself and on the links attached to the switching element. A slight movement of the holding member is necessary, on the one hand, if this limb is to be automatically returned from position V to position X after the self-releasing recording has taken place, while on the other hand the borrowed mobility is also a condition for the movement of the holding member to have a neighboring one Member, for example the aperture setting member, is not moved.

The technical problem on which the invention is based relates to the creation of a locking device for the switching element, which safely excludes unintentional adjustment of the same and does not have the disadvantages mentioned.

According to the invention, this object is achieved by « that a locking element that can be released by hand is arranged on the cam side " which the switching element in individual or all of its Sinatellagen secures

This design of a locking device for the switching element creates the advantage that the 7-bottom construction is not new additional conditions with regard to space requirements and Torkenrungen for the puncture security is made more difficult) rather remain the Conditions for the locking structure remain unchanged «while the locking element is arranged on the camera» where in spatial terms There are no such great restrictions in relation to the ratio as there are on the spanking. In addition, a trained according to the invention Locking devices are also used when the switching element has an actuating handle that protrudes only slightly from the housing possesses, as is often the case in practice

In Pig. 1 is a photographic lens shutter which is attached to the front plate 2 of a camera in a manner known to itself, for example by means of oinea screw-on ring 3 is. In a manner also known per se, on the rear side of the closure is a holding element for an M, X lightning contact device and for a built-in forward drive, a ring 4 is arranged coaxially to the VersohluSachse. This ring has a Operating handle 4a. In a further known manner, the lock is in a tube-like rope 2a of the camera front plate Arranged a little deeper, but only to the extent that the exposure time is one ring 5 can still be operated easily

According to the invention, there is now a detachable camera side Arranged locking member for the Sohaltglied 4, by means of which the switching element, depending on the choice, in individual or in 3sinen all Adjustments can be secured. A simple structure is obtained if a spring-loaded locking member is used as a locking member

Sewing plane of the Söualtgllede perpendicular direction movable Lever is arranged de? by means of pegs trained on him, such as recesses »depressions, bores or stops, that Switching element secures. This is done in the examples duroh interaction of the locking element with the operating handle of the switching element.

In order to save space and the parts hebeiförmige locking member is formed as a ^V on one side attached to the camera, the erwohnten detents or abutments carrying member, the 1st made of resilient material and by virtue of its inherent resilience with the switching member is engaged. A leaf spring 6 is preferably used as such a self-resilient part.

When arranging the Vez-lock on the camera according to Figi 1 is the leaf spring by means of two rivets or screws attached to the inside of the closure receiving tube 2a. As can be seen from Figures i to 3, the leaf spring is arranged in the tube in such a way that it only takes up the space determined by its thickness in the radial direction. A room in this order of magnitude is usually found in a VersohluB arrangement of the type shown between the outer wall of the lock and Tube inner wall available or can be made of a small one Achieve milling easily. The leaf spring also carries a handle β which passes through a slot arranged in the tube 2a 2b protrudes and is therefore accessible from the outside.

In Flg. 2 it is shown that the operating handle 4a in one Section 2c of the tube 2 is movable. The handle is opposite adjustable to the 2a marks V, X and M arranged on the tube, whereby one movement beyond the mark M and the mark V respectively is prevented by the limitation of the cutout 2o.

In Figures 3 and 4 or 5 and 6, two possible embodiments are sformen for the leaf spring serving as a locking member and its

57a, 52/03. 1719640. Alfred Gauini «G.m.b.H., Calmbadi / Enz. I photc-graphic Camera with lens switch. 17. 1. 56. G 12894. (T. 12; line 2)

Shown cooperation with the switching element.

In Fig. 3 it is assumed that the switching element should only be ^{secured in the setting directions "M ^ to X H} and ^M X to M-, while the movement path from V to X should be free to allow automatic return of the switching element after the self-timer -To enable recording in a manner known per se. Furthermore, the operating handle 4a of the switching element has a large width in relation to the adjustment path.

to lock the switching element 4 on its handle 4a reach in the desired positions au, there is a projection 6a on the leaf spring 6 shown in more detail in FIG. 5 and on the actuating handle 4a a rectangular recess 4b is formed. With setting M, the switching element is locked in the manner shown » that the projection 6a into the recess 4b under the action of the Sigen spring the spring 6 engages. If you operate the handle 8 in the direction of the arrow by Pig. 1, that is, downwards "the locking element is released" and the holding element can be moved to the X or V mark. If, on the other hand, the switching element is in position X, the edge 4c of the operating handle 4a rests against the edge 6b of the projection 6a of the spring 6. Switching to M is therefore first allowed »if the handle 8 is again in the direction of the arrow in Fig. is moved downwards.

The device shown in Fig. Λ assumes that that the holding member should be lockable in all mounting positions} and the width of the operating handle is essential smaller than the handle width gomä3 Fig. 3. The when executing The leaf spring used according to FIG. 4 is shown in more detail in FIG. It has two protrusions 6c and 6d. The gap formed by these corresponds to the width of the actuating handle 4a. In setting X, the operating handle lies in this gap, while in the setting positions H and V, the operating handle is in contact with the Outer edge of the projections 6o or 6d takes place. Loosening the spring 6 from the locked position is done again by operating the handle 8th.

Ensure the locking devices described above a secure locking of the switching element in its single digits » at the same time the advantage of a particularly simple »space-saving structure that is covered from the outside is created let. Which of the spring types shown is used here » depends on the ratio of the width of the actuating handle dea Sohaltglieda to the Verotellweg. Furthermore, the springs can do so to be educated »that the constituent element depending on the choice in individual or all of its setting items can be derived.

The deflection area of the leaf spring 6 in the direction of the arrow from Fig. 1 must correspond approximately to the thickness of the retaining ring 4 »what at the design and arrangement of the spring shown is readily guaranteed.

In the figures 7 to 10 two locking devices different from the previous figures are shown. The order the shutter on the dsr camera is here in a similar way to made in Fig. 1.

In Figures 7 and 8, a loop 9a is bent on the leaf spring 9 as a stop, with which the operating handle 4a of the switching element cooperates. This stop 9a protrudes through a rectangular cutout 2d of the front panel of the camera and lies in the plane of movement of the operating handle 4a. As in FIG. 3, it is also assumed in these figures that the holding element should be secured against shifting from "M naoh X ^{! 1} or from" X to Yes "while it is freely movable from X to V.

As can be seen, that is required for the leaf spring 9 Requires little space · The necessary space can, if necessary, through Milling under the camera front plate can be created.

In FIGS. 11 and 12 there is a further type of embodiment for a locking element and for its interaction with the switching element shown. A lever-shaped locking member under the action of a spring can be moved here parallel to the plane of movement of the Sohaltglledfe.

In FIG. 11 there is a lever 12 as such a locking member arranged, which is under the action of a spring 13. On the other hand, in FIG. 12 an element 14 made of resilient material is present Arranged as a locking member, by virtue of its inherent resilience with the Switching element is engaged. Both the lever 12 and the resilient part 14 are similar to the spring 9 in the Figures 7 to 10 arranged under the camera front panel. A pin 15 attached to them protrudes in a slot 2f Front wall and is used to release the locking device.

On the actuating handle 4a of the holding element there is again a Fixed pin 11 that pierces the front wall of the camera. With this The locking members 12 and 14 work together by means of recesses or stops 12a and 14a, respectively.

In FIG. 11 the prerequisite is met that the switching element should be blocked in all setting positions, while in FIG. 12 a blocking only for the switching movements from ^W X to M "and" M to X? should take place. Moving the switching element out of a secured setting? other settings are only possible when the pin 15 is actuated in the direction of the arrow and the engagement between the specr links 12 or 14 and the pin 11 is thereby released.
