A GUIDE RAIL ASSEMBLY HAVING A SYNCHRONIZED SLIDING MOVEMENT FOR SLIDABLY OPENING AND CLOSING A DRAWER WITHIN AN ARTICLE OF FURNITURE IS DISCLOSED. THE ASSEMBLY COMPRISES A SUPPORT MEANS (10) FOR FIXING SAID ASSEMBLY TO THE ARTICLE OF FURNITURE; A FIXED GUIDE (20) MOUNTED ON THE SUPPORT MEANS AND FOR RECEIVING AN INTERMEDIATE PULL OUT RAIL (30), AND HAVING A PROTRUSION (21) ON THE UPPER SURFACE OF SAID FIXED GUIDE, WHEREIN THE PROTRUSION PROJECTS INTO THE SPACE WITHIN THE INTERMEDIATE PULL OUT RAIL; AN INTERMEDIATE PULL OUT RAIL CAPABLE OF SLIDING BACK AND FORTH RELATIVE TO THE FIXED GUIDE; AND AN OUTER PULL OUT CHANNEL (40) FOR ATTACHMENT TO THE DRAWER AND BEING CAPABLE OF SLIDING BACK AND FORTH ON THE INTERMEDIATE PULL OUT RAIL RELATIVE TO THE INTERMEDIATE PULL OUT RAIL AND THE FIXED GUIDE. A SYNCHRONIZING MEMBER (50, 60) IS PIVOTABLY MOUNTED ON THE INTERMEDIATE RAIL (30), THE SYNCHRONIZING MEMBER COMPRISING A FORWARDLY-EXTENDING SECOND ARM (52, 62) AND A REARWARDLY-EXTENDING FIRST ARM (51, 61) THAT EXTEND IN GENERALLY OPPOSING DIRECTIONS FROM A CENTRAL PORTION (53, 63) THAT CONTAINS THE PIVOT POINT (53A. 63A). EACH OF THE ARMS TERMINATES IN A RESPECTIVE ROLLER (51A, 52A; 61A, 62A) THAT ENABLES THE SYNCHRONIZING MEMBER TO TRAVEL ALONG THE BOTTOM SURFACE OF THE OUTER PULL OUT CHANNEL (40), AND THE REARWARDLY-EXTENDING FIRST ARM (51, 61) INCLUDES A BEND (51B, 61B) TO DEFINE AN ELBOW. THE CENTRAL PORTION (53, 63) IS ADAPTED TO INTERACT WITH THE PROTRUSION (21) SO AS TO SWITCH THE SYNCHRONIZING MEMBER, DURING AN OPEN OR CLOSING ACTION OF THE ASSEMBLY, BETWEEN A FIRST CONDITION IN WHICH THE ELBOW OF THE FIRST ARM ENGAGES THE REAR END OF THE OUTER PULL OUT CHANNEL AND LOCKS THE OUTER PULL OUT CHANNEL (40) TO THE INTERMEDIATE RAIL (30), AND A SECOND CONDITION IN WHICH THE CENTRAL PORTION IS ENGAGED BY THE PROTRUSION TO LOCK THE FIXED GUIDE (20) TO THE INTERMEDIATE RAIL (30). |
