Abstract: A TOUCH DEVICE FOR CABINET DRAWERS OR CLOSURES WHICH WILL ACT TO AUTOMATICALLY PARTIALLLY OPEN THE DRAWER, CLOSURE OR DOOR UPON MANUALL ACTUATION AND MAY LATCH THE DRAWER OR DOOR IN CLOSED POSITION, SO THAT THE DRAWER OR DOOR DOES NOT REQUIRE A HANDLE OR PULL ON THE EXTERIOR SURFACE THEREOF. THE DEVICE INCLUDE A HOUSING MOUNTED IN THE CABINET OR ENCLOSURE WITH AN ELONGATED PLUNGER PROJECTING FROM ONE END, WITH THE INNER END OF THE PLUNGER ENGAGING A GENERALLY RECIPROCABLLE ACTUATING MEMBER HAVING LIMITED ARCUATE MOVEMENT. A U-SHAPED PUSHER IS SPRING-BIASED TO ENGAGE THE ACTUATING MEMBER, AND THE ACTUATING MEMBER IS PROVIDED WITH A HOOK AT ONE END COOPERATING WITH THE INNER ENLARGED AND RECESSED END OF THE PLUNGER AND A LATERALLY EXTENDING SECOND HOOK AT THE OPPOSITE END OF THE MEMBER COOPERATING WITH AN OPENING FORMED IN THE SIDE WALL OF THE HOUSING. MOVEMENT OF THE DRAWER OR CLOSURE INWARD RETRACTS THE PLUNGER AND CAUSES THE ACTUATING MEMBER TO ENGAGE THE HOUSING AND PLUNGER TO PREVENT OUTWARD MOVEMENT THEREOF, AND PRESSURE EXERTED ON THE CLOSED DRAWER OR CLOSURE CAUSES RELEASE OF THE ACTUATING MEMBER SO THAT THE SPRING BIASES THE PLUNGER OUTWARDLY TO PARTIALLY OPEN THE DRAWER OR CLOSURE.
