3. PREAMBLE OF THE DESCRIPTION: The following complete specification particularly describes the invention and the manner in which it is performed. FIELD OF THE INVENTION

The present embodiment relates to a sliding door, and more particularly to an eccentric assembly to be connected with the sliding door.

BACKGROUND OF THE INVENTION In general, doors are widely used in buildings or homes to allow access to enter the building or other premises. The doors are provided with a side hinge that enables the door to open or close, upon rotation from the end opposite to the hinge. Such doors occupy space while opening, as they extend into the room or outside the room upon rotation. This arise a need for providing different kind of doors that are more compact while in operation and are easy to use, therefore concept of sliding door came into picture.

Sliding doors are widely known in prior art as is disclosed in DE patent number 10334920A1 using a roller that slides in a roller carriage for sliding the door. Other references such as KR patent number 20030041670A and TW patent number 202100857A discloses similar assemblies for door sliding including a control mechanism to control the door sliding in cases where required.

The major problem for door sliding mechanisms lies in intricacies of the design of assembly involved in sliding mechanism. A number of components are used in such kind of assembly that increases weight on the door and thereby creating difficulty in door operation. Door sliding assemblies need to be installed correctly to avoid any accident such as lag in opening or closing of the door. Wrong installation of door assemblies can lead to excessive wear and tear of sub-assemblies involved in door sliding mechanism, to door and even to floor as well. Fitting of door leaf with conventional assemblies is much more time consuming, difficult and burdensome as such assemblies involve greater number of components to be settled. Conventional door sliding mechanisms do not provide a way to try different variants of doors such as single leaf door, double leaf door, curved door, side haul door and under-slung door etc with the same assembly. A specific assembly for numerous door variants is required to achieve the purpose and thus involve more time to re-install the assembly. Keeping in view the intricacies involved in such mechanisms, there is a need for simpler mechanism with a smaller number of components, that enable the installer or mechanic to install doors correctly and, in a fail -proof manner. Further a standard mechanism for easy installation and easy removal for door of various kinds is required. SUMMARY OF THE INVENTION
