摘要： A display device in which one or more prisms are moved between at least two fixed positions. Each prism has an image surface, an object surface and a reflecting surface and there is indicia placed adjacent the path defined by movement of each object surface. The indicia is visible at an image surface in only one position of the prism.

摘要： A doorknob assembly of the type wherein a button, generally centrally located in the handle, is effective to lock and unlock a lock mechanism. The button to lock and unlock the door moves within a passage, a portion of which may have a suitable indicia, for example a colored band, positioned on it. The button includes a prism with a reflecting surface, object surface and image surface. When the reflecting surface is positioned adjacent the indicia in the passage, there will be a display visible at the outer transparent area of the button. Thus, the condition of the lock mechanism is readily apparent to one using the doorknob.

摘要： A display device including a prism having an object surface, an image surface and a reflecting surface. The reflecting surface is symmetrical in configuration and the object surface is outside the reflecting surface. There is indicia positioned adjacent and outwardly spaced from the object surface such that relative movement between the object surface and indicia along the axis of symmetry of the reflecting surface changes the display visible at the image surface.

摘要： A display device using an arcuate-shaped prism having an object surface, an arcuate-reflecting surface and an image surface. There is fixed indicia positioned adjacent the object surface and movable indicator members arranged to move in a path adjacent the object surface such that the display at the image surface will provide useful information in the form of the relationship between the fixed indicia and movable indicator members.
