Abstract: A product retrieval mechanism for vending machines that permits collection of varying size products at a first level yet presents such products for collection at a raised height to make retrieval more convenient. The retrieval mechanism utilizes a movable floor within the hopper that movable between a lowered position and a higher position for presenting the product at a higher retrieval point relative to the floor upon opening of the hopper.

Abstract: A friction tilt mechanism is specially configured to provide precisely controllable tilt angles to devices requiring smooth and stable angular adjustability, by virtue of employing one or more unique frictional tilt devices. Each friction tilt device includes a pair of bronze bearing blocks, one responsive to precisely applied compressive forces to produce user controllable amounts of static and rotational friction to the tilt axis. When a pair of the friction tilt devices are arranged on a support adapted to carry a flat panel display, smooth and precise viewing angle adjustments are readily accomplished and stabily retained for a wide range of display weights.
