Embodiment Construction

[0032] figure 1 An arrangement for converting a rotary shutter is shown, which comprises a carrier plate 1 on which is arranged an interchangeable shutter 2 on which the shutter is mounted. In all figures, the shutters are simply presented as blank areas. exist figure 1 In the exemplary embodiment shown, the tray 1 is equipped with seven light-cutting blades 2 and a free position for direct lighting by the lamp.

[0033] All the light cutting sheets 2 are attached to the tray 1 by means of a central holding device 10 . A part of each photocutter 2 is made of a sheet 3 whose shape is used to attach the photocutter 2 to the central holding device 10 . The shutter is fixed into a rotating shutter carriage drive 6 on ball bearings. Fixed connection means, such as screws 4 with cylindrical head in the represented embodiment, are used to fix the ball bearing outer ring 5 to the lamella 3 of each light chopper 2 . The bearing balls are freely located in the outer ring 5 of the b...

Abstract

For lighting equipment for illumination of theatre and show stages and platforms there is designed equipment for quick change of rotary gobos (302) comprising a carrier disc (301) supporting interchangeable segments with the gobos. The individual segments are attached at the carrier disc by springs (303) which register the position of the segment on the gobo carrier while at the same time holding the segment in place.

Description

[0001] related application [0002] This application claims priority to US Utility Model Application No. 12749,690, filed March 30, 2010, which claims priority to US Provisional Application No. 61 / 165,253, filed March 31, 2009. technical field [0003] The invention relates to equipment for changing a rotary shutter provided with a carrier disc supporting an interchangeable shutter with a shutter. Background technique [0004] The term shutter relates to an image to be projected as a slide over a relatively large distance. Due to the high temperatures of the respective light sources, such images are typically formed on metal, glass or any suitable substrate. To increase the effect obtained, the shutter is rotated, since moving images attract more attention than still images. Rotary shutters do not need to rotate continuously; therefore rotation of the shutter is dependent on activation of the drive motor. Typically these systems are set up on a circular carrier with a cen...
