The system includes at least one inner and outer sliding door slidably coupled to corresponding guide rails. The guide rail that is coupled to the outer sliding door is selectably moveable by a sliding door mechanism between a first and a second position. In the first position, a user can slide outer and inner sliding doors along said guide rails, whereas in the second position, a surface of the outer sliding door is substantially flush with a surface of said inner sliding door. ## Claims ### Claim 1 A sliding door mechanism comprising: a support onto which said sliding door mechanism is mounted; and at least one inner and outer sliding door slidably coupled to corresponding guide rails, wherein the guide rail that is coupled to the outer sliding door is selectably moveable by a sliding door mechanism between a first and a second position, wherein the first position enables a user to slide outer and inner sliding doors along said guide rails, and wherein in said second position a surface of said outer sliding door is substantially flush with a surface of said inner sliding door. ### Claim 2 (depends on 1) The sliding door mechanism of claim 1, wherein said support is a top of cabinet. ### Claim 3 (depends on 1) The sliding door mechanism of claim 1, wherein said mechanism comprises: at least one rod rotatably affixed to said support, said rod having a thread; and an annular device threaded onto said thread, wherein said annular device is fixedly adjusted to said outer guide rail; wherein rotation of said rod causes longitudinal displacement of said annular device along said thread, thereby causing a longitudinal displacement of said outer door. ### Claim 4 (depends on 2) The sliding door mechanism of claim 2, wherein the direction of movement of said annular device in said thread depends on the direction of rotation of said rod. ### Claim 5 (depends on 1) The sliding door mechanism of claim 1, wherein said rod is rotated by a drive, which is comprised of at least one of the following group: a) a belt drive; and b) a cogwheel drive ### Claim 6 (depends on 5) The sliding door mechanism of claim 5, wherein said belt drive comprises at least one belt wrapped around said rotating drive. ### Claim 7 (depends on 5) The sliding door mechanism of claim 5, wherein said drive is operable by at least one of the following means: a) manually; b) electrically; c) pneumatically; and d) hydraulically. ### Claim 8 (depends on 1) The sliding door mechanism of claim 1, wherein said inner and outer guide rails have grooves. ### Claim 9 (depends on 1) The sliding door mechanism of claim 1, wherein said inner and outer guide rails are substantially parallel to each other. ### Claim 10 (depends on 1) The sliding door mechanism of claim 1, wherein an inner and an outer hanging hardware couples said inner and outer sliding door to said inner and outer guide rail, respectively. ### Claim 11 (depends on 10) The sliding door mechanism of claim 10, wherein said hanging hardware comprises a bridge element that extends up and over said inner door and said inner guide rail. ### Claim 12 (depends on 5) The sliding door mechanism of claim 5, wherein an activation switch is operatively associated with said drive such that the drive retracts the outer door into the second position upon an activation of said activation switch. ### Claim 13 (depends on 1) The sliding door mechanism of claim 1, wherein said mechanism comprises: a) at least one bearing having an inner and an outer ring, wherein said outer ring is affixed to said support; b) a first rod suitably coupled to a displacement drive and rotatably connected to said inner ring; and c) a second rod suitably coupled to said outer guide rails and rotatably connected to said inner ring; wherein operating said displacement drive enables the rotation of said inner ring to selectably move said outer sliding door into said first and said second position. ### Claim 14 (depends on 13) The sliding door mechanism of claim 13, wherein inner rings of a plurality of said bearings securely hold therein a rod thereby enabling said displacement drive to rotate said plurality of bearings. ### Claim 15 (depends on 13) The sliding door mechanism of claim 13, wherein said bearing has a protrusion substantially aligned with said second rod to confine upward movement of said second rod, thereby preventing detachment of said outer guide rail from said support. ### Claim 16 (depends on 13) The sliding door mechanism of claim 13, wherein said displacement drive is operable by at least one of the following means: a) manually; b) electrically; c) pneumatically; and d) hydraulically. ### Claim 17 (depends on 13) The sliding door mechanism of claim 13, wherein said displacement drive enables selectable displacement of said first rod into a closing and opening position, wherein: a) the displacement of said first rod into said closing position causes said inner ring to rotate in a direction causing said second rod and said outer guide rail which is connected thereto to retract into said second position; and b) the displacement of said first rod into said opening position causes said inner ring to rotate in a direction causing said second rod and said outer guide rail to be pushed outwardly into said first position.
