The arms are rotatable between a downwardly and rearwardly directed position and a forwardly directed position extensive of the frontal area for exposing a shelf or basket. Each of the pair of arms is engaged with slots in a guide plate fixed at one side of the shelf or basket, whereby the basket is driven linearly, by the arms, between a retracted position inside the cabinet to a frontal position, while the arms traverse the slots, and then the arms lift the basket in an arc to an extended and raised convenient height. Such movement is facilitated by a motor driven linear actuator or by pulleys rotated by drive cords or belts.Field of SearchWITH MOVABLE COMPONENTSPlural, diverse types Sequentially movable Pivoted closure, horizontally movable component Having biasing means For a pivotal structure Continuously leveled Having power driven means Rotary operator Spaced horizontal guides for article supports Pivotal, on pivoted link Horizontally movable (e.g., drawer) Lever type Particular oven shelf, rack, or support therefore Having particular shelf or rack Slidably supported Of wire Dishwashing machine rack With means to hold work holder in draining position above treating liquid With work feeding and/or discharging means Including separate belts for forward and reverse PLURAL BELTS OR PLURAL OUTPUT LOADS SYSTEM INCLUDING SPACED PULLEYS INTERCONNECTED BY A BELT DEVICE OR MEMBER FOR CONTACTING AND GUIDING MOVING CABLE Plural elements or element with plural cable contacting regions At least two of the elements having noncollinear axes of rotation Including flexible drive connector (e.g., belt, chain, strand, etc.) With pulley 414/DIG917 | |
