Abstract
ABSTRACT
A GUIDE TRACK
A guide track (20) for receiving a guide bracket (26) of a sliding door (1), the guide track (20) including a longitudinal opening (22) having a width adapted to accommodate and guide a guide bracket (26), during use, and an internal channel (24) within the track (20) communicating with the longitudinal opening (22) along the length of the track (20), wherein the width of the internal channel (24) is greater than the width of the longitudinal opening (22).
This arrangement enables debris falling into the guide track to be swept along the internal channel (24) without blocking the track (20) and causing malfunction of the sliding doors.

Claims (10)
1. A guide track for receiving a guide bracket of a sliding door, the guide track including a longitudinal opening having a width adapted to accommodate and guide a guide bracket, during use, and an internal channel within the track communicating with the longitudinal opening along the length of the track, wherein the width of the internal channel is greater than the width of the longitudinal opening.
2. A guide track as claimed in claim 1, wherein the width of the longitudinal opening increases towards the internal channel.
3. A guide track as claimed in claim 1 or claim 2, wherein the width of the internal channel is more than twice the the width of the longitudinal opening.
4. A guide track as claimed in any preceding claim which is made of a low friction material.
5. A guide track as claimed in any preceding claim which is manufactured by extrusion from a plastics material.
6. A guide track as claimed in any preceding claim which is resilient and bendable.
7. A guide track substantially as hereinbefore described with reference to and as shown in figures 3 and 4 of the accompanying drawings.
8. A sliding door guide apparatus comprising a guide bracket for mounting on a sliding door and a guide track as claimed in any preceding claim, wherein the guide bracket is substantially planar and has a thickness slightly less than the width of the longitudinal opening of the guide track, thereby enabling the bracket to move along the longitudinal opening as the door slides, during use.
9. A sliding door guide apparatus as claimed in claim 8, wherein the guide bracket is a planar metal plate.
10. A sliding door guide apparatus substantially as hereinbefore described with reference to and as shown in figures 1, 3 and 4 of the accompanying drawings.
