DE633325C - Electric light meter on photographic cameras - Google Patents

Description

The invention relates to one with the lens carrier, its guide or bearing part (Walking floor o. The like.) Connected, with this see moving into the position of use electric light meter on photographic cameras.

Exposure meters of this type are known per se. With them the photosensitive ones had to be Cell-protecting parts, if any, by hand be operated.

The essence of the invention is that the lens carrier frame or the lens carrier by linkage, lever or the like.

so with the cover parts, for. B. flaps, des electric light meter is connected that this automatically exposing or Cover the cell and cause the light meter over the floor Pivot into its free and use position or bring it backwards over the walking floor, wherein the exposure meter by lever o. The like. With the lens shutter diaphragms actuating parts is releasably connected, so that these together the aperture control effect by the exposure meter. Several embodiments of the subject matter of the invention are shown in the drawing reproduced, namely shows

Fig. Ι the first embodiment in side view with the exposure meter swiveled out to the bottom of the camera and open Closing flaps,

Fig. 2 a front view of Fig. I, cover flaps to the exposure meter closed, . Fig. 3 a second embodiment of a round type, cover flaps sprung outwards, automatically reversible to the exposure meter by means of pins,

Fig. 4 shows a third embodiment in connection with an automatically righting one Lens support frame by lever linkage for the purpose of bringing the exposure meter into its use and Non-use position, closing flaps underneath and to the walking floor (cover of the Camera housing) connected by swivel rods.

For embodiment 1
(Fig. Ι and 2)

On the running floor / which can be pivoted in a known manner relative to the camera housing g, the electrical exposure meter / s are rotatably mounted ^{between bearings / 2.} When the camera housing is opened, the latter is moved from its position in the camera's inner housing g ^{1, shown} in broken lines in FIG. The closing or protective flap are then swiveled outwards, and the light meter m is ready for use.

It will be understood that by suitable transmission means, e.g. B. can be derived from the

Light meter nt moving out transmission members (lever: etc.), which is arranged with the lens shutter v ^ .- which in the usual way, partly (support plate or the like) ο of the lens carrier frame s, ie. Aperture system connected parts (pull or swivel rods or the like) releasably connect, the corresponding regulation (adjustment of the aperture from the exposure meter) can take place. '

For version 2 (Fig. 3)

The electric meter "tn is located here on the track P of the figurative, not shown lens supporting frame s. He is, notwithstanding ι from that in Fig. And designed two reproduced rectangular embodiment round cans like, m To capture for folding the exposure meter toward the baseboard / and the track P is a projection tn ^1. The same can be shaped so that it is gripped at its outer end ² by a resilient locking hook known per se and therefore not shown, so that "this is actuated when the lens support frame is moved out into the infinite position is, releases the exposure meter tn and allows it to pivot about its storage ß in the position of use by the coil spring placed around the bearing axis. At the same time, approaches k ^{1 of} the end plates (flaps) k leave their abutment pins k ² , so that the flaps pivot outward through the springs / ^1.

For embodiment 3 (Fig. 4)

The lens support frame , which is erecting itself in a manner known per se, carries a linkage h which can be pivoted about axis α at one end and which is connected to the exposure meter m at its other end at a ^{1 by an axis pin.} By means of this linkage, the latter is brought into the non-use position indicated in dashed lines when the running floor / to the camera housing g is pivoted. -.

During this pivoting, a lever A ¹ pivotable about bearing a ² , which is articulated to the flap at Φ, presses it into its cover position for the exposure meter. The other flap k, since it is connected to the first-mentioned through axes a ⁴ =, a ^b rotatable linkage A ² , is also pivoted into the cover position. With all of the above. Means advantageously consists of exposure meter m or its termination .klappen & or both to the ^interior; floor ⁱ casing g ^1, Run I, track P, Obwalden • jgj ^ ttvträger ο or lens support frame in: B ^ rjjjhrung points coming made of elastic material.
