Drive chain element

A drive chain assembly for operably connecting a slat assembly of a roll top cover to a drive rail, the drive chain assembly comprising:

• a plurality of operably connected drive chain elements;
• each drive chain elements including:
• an elongate body that defines a longitudinal axis and first and second ends, an inner side of the elongate body configured for engaging an end portion of the slat,
• first and second hinge elements disposed at the respective first and second ends of the body, the first and second hinge elements configured to define a hinge arrangement between adjacent drive chain elements that facilitates relative pivotal movement therebetween, and
• first and second pins disposed in a spaced arrangement along an outer side of the body and extending outwardly therefrom;
• wherein the first and second pins are configured for operably contacting a drive system during operation of the roll top cover;
• and
• wherein the first pin is rounded rectangular in cross section to reduce a size of the drive system.

A roll top cover assembly, comprising:

• a drive system including a track and a cog;
• a drive chain including a plurality of operably connected drive chain elements, each of the drive chain elements including:
• an elongate body that defines a longitudinal axis and first and second ends, an inner side of the elongate body configured for engaging an end portion of the slat,
• first and second hinge elements disposed at the respective first and second ends of the body, the first and second hinge elements configured to define a hinge arrangement between adjacent drive chain elements that facilitates relative pivotal movement therebetween, and
• a first pin and a second pin disposed in a spaced arrangement along an outer side of the body and extending outwardly therefrom, the first pin driving and not guiding the drive chain and the second pin guiding the drive chain around the drive system.
