<p>1,057,983. Photographic cameras. VOIGTLANDER A. G. April 13, 1964 [April 13, 1963], No.15210/64. Heading G2A. A photographic camera having a cap into which is built a flash-lamp holder, is provided with a hinged cover which encloses the holder and serves to disengage a flash-lamp from the holder. The holder comprises a base 4 secured to the camera body 1 and two contact springs 5 which hold a flash-lamp 8 in position. The cover 12 is hinged to the back of the camera by a pivot pin 13 on which is mounted a spring 16 to urge the cover into the open position (Fig. 1). A section 112 of the cover, extending at right angles thereto, carries at its free end an insulating element 22 of wedge-shaped cross-section. As the cover is hinged into the closed position the element 22 forces the springs 5 apart to release their grip on the flash-lamp 8. A pin 23 which projects from the inside of the cover 12 contacts the flashlamp and forces it from the holder. When the cover is completely closed the pin 23 is gripped between the springs 5 which overcome the action of the spring 16. In a second embodiment (Fig. 8) the ejection of the lamp 8 is effected by further outward pivoting of the cover. The ejector element 26 consists of a part 260 formed with a central opening 27 for the passage of the lamp base, and a part 261 extending beneath the opening 27. A screw projects from the part 261 into a cavity of the holder base and is urged by a spring 28 into the cavity. On further pivoting of the cover beyond the normal open position lugs 32, 33 carried on side walls of the cover abut against the element 26, lifting it so that the part 261 passes between the springs of the holder and forces the lamp 8 upwards.</p> |
