Engagement mechanism for engaging a roller with a lower track of a sliding door

Abstract

An engagement mechanism of a hanging sliding door including a roller for rolling along a lower track; a connector for connecting the engagement mechanism to the respective sliding door, where the connector includes a supporting portion and an extended portion allowing holding the roller at a predefined distance from the respective sliding door; and an elastic member such as a spring connected to the roller in a manner that allows the roller to move along an axis of the elastic member that is substantially perpendicular to the sliding door tracks. The extended portion includes a holding member for holding the elastic member there-above in a manner that allows the elastic member to apply force from below the roller towards the lower track located above the roller for maintaining engagement between the roller and the lower track throughout the sliding movement thereof.

What is claimed is: 
     
         1 . An engagement mechanism of a hanging sliding door of a compartment having a lower track and an upper track for said sliding door to slide therethrough, said engagement mechanism comprising:
 at least one roller for rolling along a lower track;   a connector for connecting said engagement mechanism to the respective sliding door, said connector comprises a supporting portion, which connects to said sliding door and an extended portion, which movably connects to said roller; and   an elastic member connected to said roller in a manner that allows the roller to move along an axis of said elastic member that is substantially perpendicular to said sliding door tracks,   
       wherein said extended portion comprises a holding member for holding said elastic member there-above in a manner that allows the roller to apply force from below towards the lower track located above said roller for maintaining engagement between said roller and said lower track throughout the sliding movement of said sliding door. 
     
     
         2 . The engagement mechanism according to  claim 1 , wherein said elastic member comprises a coiled spring. 
     
     
         3 . The engagement mechanism according to  claim 2 , wherein said extended portion comprises an opening and a protruding member enabling to hold said coiled spring from below thereby allowing flexibly pressing said roller to said lower track from below. 
     
     
         4 . The engagement mechanism according to  claim 2 , wherein said roller connects to said extended portion via a fastening mechanism configured to fasten said roller to said extended portion in a manner in which the roller is positioned at a distance from said extended member. 
     
     
         5 . The engagement mechanism according to  claim 4 , wherein said extended portion comprises an angular structure comprising (i) a first portion that angularly connects to said supporting portion, said supporting portion connects to said sliding door, and (ii) a second portion angularly connected to said first portion. 
     
     
         6 . The engagement mechanism according to  claim 5 , wherein the angle between said first portion and supporting portion is substantially straight and the angle between said first portion and second portion is substantially straight. 
     
     
         7 . The engagement mechanism according to  claim 1  further comprising an adjustment mechanism for allowing fine adjusting of the location of said engagement mechanism in respect to the door. 
     
     
         8 . The engagement mechanism according to  claim 1  of a compartment having at least two hanging sliding doors: an inner door and an outer door, said compartment comprises a fame-structure, which is a profile having a first lower track and a second lower track connected to one another wherein said engagement mechanism is configured for sliding the inner door over said first lower track.
