ABSTRACT:
A rail assembly includes a first rail formed with a stopping protrusion, and a second rail mounted slidably on the first rail and formed with an engaging protrusion. The engaging protrusion includes a head body that has opposite top and bottom ends and that gradually reduces in cross-section from the top end to the bottom end. The bottom end of the head body is formed with a curved nose that protrudes downwardly therefrom and that is blocked by the stopping protrusion when the second rail is moved frontwardly to a front position relative to the first rail. The head body is elastically deformable so as to be compressed by the stopping protrusion to an extent that the nose is able to slide over the stopping protrusion when the second rail is further moved frontwardly from the front position by a pulling force.
