A latch mechanism positioned at the intermediate extents of the adjacent rail components to hold such components in an aligned orientation including a saddle having opposed parallel faces and a central aperture defined in between the opposed faces. Each opposed face has at least an aperture and a plurality of guide slots provided lengthwise of the saddle. The central aperture is adapted to receive opposed rail components therein. Fastening means extend through the aperture to pivotally couple the saddle with the opposed rail components. An urging block is mounted within the central aperture of the saddle at substantially the center portion of the saddle, in between the opposed rail components. Guide pins are slidably mounted within the guide slots, and a flexible strap is provided to connect the guide pins to the urging block. Upon the actuation of the urging block, the flexible strap will be activated to move the guide pins in respective slots to a position in which the rails components are released to move to a collapsed orientation from an erect deployed orientation. |
