20080198470 | QUICK ADJUSTMENT EYECUP FOR OPTICAL VIEWING INSTRUMENTS - An optical viewing instrument is disclosed generally comprising an eyecup with a cylindrical surface and a housing with an ocular lens portion that has a corresponding cylindrical surface for slidably receiving the eyecup. The ocular lens portion has bearings protruding therefrom, and the eyecup includes longitudinal channels for receiving the bearings as the housing receives the eyecup and curvilinear channels for accommodating the bearings as the eyecup is rotated. In certain embodiments, the ocular lens portion also includes a detent, and the eyecup has a plurality of grooves into which the detent clicks as the eyecup is rotated. In some embodiments, the curvilinear channels are spiral shaped to cause axial motion of the eyecup when rotated. | 08-21-2008 |
20090046369 | EYECUP - An object of the present invention is to provide an eyecup such as a horn-shaped eyecup and the like capable to easily attach to a standard eyecup. The eyecup includes an intermediate member | 02-19-2009 |
20100149645 | OPTICAL OBSERVATION APPARATUS - The apparatus includes a supporting member disposed at an outer circumference of the ocular optical system and an eyepiece cup. A first member thereof includes a cam follower and a second member thereof includes a cam groove to move the eyepiece cup in an optical axis direction with rotation of the eyepiece cup and an introducing groove through which the cam follower is introduced to the cam groove. One member of the first and second members includes an engaging portion, and another member thereof includes a stopper engaging with the engaging portion to prevent rotation of the eyepiece cup in a direction in which the cam follower is returned from the cam groove toward the introducing groove. The stopper formed integrally with another member is elastically movable so as to be located at and retreated from an engaging position to be engageable with the engaging portion. | 06-17-2010 |
20100172026 | EYE CUP - In an eye cup for an eyepiece of an optical observation apparatus, for individual and convenient adjustment of the eye cup it is provided that a second adjusting element can be rotated in a mode dependent on a compressive force independently or together with a first adjusting element, such that a light-shield section can be positioned as desired for any distance of the adjusting elements with respect to one another. | 07-08-2010 |
20120019919 | Active Display Imaging System Provided with an Eyecup - An imaging system comprises an active display and a flexible eyecup made of a light-proof material, arranged around the active display and intended to eliminate the leakages of light between the active display and an observer. The imaging system comprises: pumping means capable of creating an air pressure difference between the inside and the outside of the eyecup, means for switching on the active display when a threshold pressure difference, called switching-on pressure Pa, is reached between the inside and the outside of the eyecup. | 01-26-2012 |
359616000 |
KALEIDOSCOPE | 3 |
20080252982 | Vertically mounted kaleidoscope - A kaleidoscopic device is provided. In accordance with one embodiment, the kaleidoscopic device may have a housing mounted within a wall and a collection drum that has a plurality of display elements. The collection drum may be intermittently rotated and/or rotated at various speeds by a driving system that has a motor. A mirror structure may be mounted within the housing and used with the display elements in order to generate a decorative kaleidoscopic effect. | 10-16-2008 |
20100302643 | IMAGE-PRODUCING APPARATUS - An apparatus ( | 12-02-2010 |
20110181959 | KALEIDOSCOPIC SYSTEM AND METHOD OF USE - A kaleidoscopic system may include a portable platform table having at least one storage compartment, a teleidoscope mounted on a swivel and gooseneck assembly, and a turntable affixed to a top of the portable platform table. The assembly may be affixed to the portable platform table to position the teleidoscope over the turntable. | 07-28-2011 |
