Plug connection for add-on devices from fotografisch. ©! Cameras.

The invention relates to the plug connection of the various Aufsatsgeräte with fotogrsfisciieii cameras. Usually the AufsteeiE devices have a ΙΓ-shaped curved I ¹ UjS and the Scirah attached to the camera two angles that surround the S ¹ UB flush when pushed in »

Both ropes are standardized with a certain tolerance * If it is now the case that the villain has a positive tolerance and the IuS a negative tolerance. In this case, a sufficiently firm connection occurs at the file of more an _f £ so that once the Sefaar consists _t that Aafsatzgerät lose "on the other hand the position of the auxiliary device is on it to the camera is not specified, and by; Loose connection results, slightly wrong setting values.

This technical part is eliminated by the invention * Per essential inventive idea lies
Sarin, there is a self-sealing clamp connection between the shoe attached to the camera and the PuS of the attachment when the device foot is pushed in when the target position is reached
is triggered · 2 for this sweck, two levers are rotatably mounted in the base of the device, the width of which
Sliding jaws can slide freely on the guide surfaces of the Sch hes until two other surfaces of the lever arms are in contact with an abutment of the shoe in the target position of the attachment device
come, the levers are rotated so that their sliding jaws tilt and a corner of the
Slide bars firmly against the Pührungsflache of the
Shoe is pressed. To maintain this pressure, the angle of inclination between the contact surfaces of the Eebel and the abutment is smaller than the coefficient of friction.

In the Seichaung there is an execution example: Invention shown.

Figure 1 shows a sehöjsatisehe view of the
Shoe and the foot in front of the
Binding.

Figure 2 shows a plan view of the Ohiß from below without the file of the clamping connection.

Figure 3 is a plan view of ά & η. iCamera shoe

Figure 4 is a plan view of the Torriciltung in
Clamping position.

In detail, 1 means the Sehtüi arranged on the camera, the two guide surfaces designed as an angle 2 for the foot 4 of the attachment

device has »This foot 4 is connected by a neck 5 to the actual attachment. Within the shoe 1, an abutment 6 is provided for according to the present. Training a simple cylinder head screw is used · The hah-Ie hem 5 of the foot 4 is now used to accommodate the clamping device. For this purpose, as can be seen from FIG. 2, the middle part of the guide strips (4) is cut away so that only the 4 corner pillars T remain. In the area thus created, as can be seen from FIG 9 three: stored in bar, when the foot is pushed into the guide strips 2 of the shoe 1, the two broad jaws of the levers S slide loosely along the guide surfaces. As soon as the foot 3 is pushed all the way into the shoe 1, the surfaces IC of the free ends of the levers 8 run against the abutment 6 »which is in the. Shoe 1 is fixedly arranged. As a result, the levers 8 are rotated about their axis 9 in such a way that the corners 11 are pressed firmly against the guide surfaces 2 of the shoe 1. As a result of the self-locking design between the Orleitflächen IO and the abutment 6, all ropes are held in the Klemrastellung after light pressure, so that an absolutely safe Terbdn & ung, which prevents tackling , is guaranteed between shoe and foot. With a little more pressure in the opposite direction, the connection is released again and the attachment can be removed in the usual way.
