<p>A sliding door structure includes a door panel 52 suspended from a rail (not shown) by two roller assemblies 56. Each roller assembly 56 comprises a toothed wheel 60 having an integral boss 62 axially slotted 64 to allow insertion into hole 66 in the door panel 52. The boss 62 locates in a recessed hole 68 in leaf 70 of a right angled bracket 72 of which upper web 74 lies flush along the top edge of the door panel 52 such that leaf 70 lies flush against one main surface of the panel 52 thus securing the toothed wheel 60 to the door panel 52 in a slot defined by ears 78 and leaf 70. A resilient leaf 80 provides a tooth 82 which engages with the toothed wheel 62 to prevent rotation thereof. A roller stem 86 having rollers 90 on each end is located through an eccentric aperture 84 in the boss 60. A tool 98 is provided to adjust the toothed wheel 60 thus altering the height relationship between the door panel 52 and the rail (not shown) on which the rollers 90 run. <IMAGE></p> |
