Title:
OPTICAL VIEWING SYSTEM AND CLAMPING DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO2002021065
Kind Code:
A3
Abstract:
An optical viewing assembly (130) for transferring image information from one image modifying device (78) to another image modifying device (74) includes first and second clamping portions (14) integrally formed at opposite ends of a hollow sleeve (12). Each clamping portion (14) has a pair of clamping legs (24, 26) that are separated from the sleeve (12) by a circumferential slot (16) to permit movement of the clamping legs (24, 26) toward and away from each other by manipulation of a locking lever (44). Movement of the clamping legs (24, 26) toward each other reduces a cross dimension of the clamping portions (14) to thereby clamp an image modifying device therein. Conversely, movement of the clamping legs (24, 26) away from each other increases a cross dimension of the clamping portions (14) to thereby release a clamped image modifying device.
