The cover is extendable for covering a length of a telescoping portion of the conveyor system. A free end of the cover is connected to the telescoping portion at a far end. A shuttle assembly is biased to retract the cover for storage, for example by rolling the cover into the shuttle assembly under spring action. The shuttle assembly may be movably mounted to the telescoping portion of the conveyor system to allow relative movement of the shuttle assembly and the telescoping portion during telescopic extension/retraction of the conveyor system. The shuttle assembly is also anchored to the base portion at least during the telescopic extension. The cover may include reinforcement bars and/or connecting magnets. An idler roller may bias the cover toward the conveyor frame. ## Claims ### Claim 1 A cover shield system for a conveyor system having a base portion and a telescoping portion, the cover shield system comprising: a cover extendable along the length of the telescoping portion of the conveyor system, said cover formed from a flexible material and configured to substantially span the width of the telescoping portion, said cover having a free end configured for connection to the telescoping portion at a first location; and a shuttle assembly biased to retract the cover for storage, said shuttle assembly being movably mounted to the telescoping portion of the conveyor system to allow relative movement between the shuttle assembly and the telescoping portion in a direction parallel to the length of the telescoping portion, wherein said shuttle assembly is anchored to the base portion at least during extension of the telescoping portion. ### Claim 2 (depends on 1) The cover shield system according to claim 1, wherein said shuttle assembly is mounted to the telescoping portion using a slidable mount or a rolling mount. ### Claim 3 (depends on 1) The cover shield system according to claim 1, wherein said free end is configured for removable connection to the conveyor system at the first location. ### Claim 4 (depends on 1) The cover shield system according to claim 1, wherein the first location is at or proximate a discharge end of the telescoping portion. ### Claim 5 (depends on 1) The cover shield system according to claim 1, wherein the cover further comprises one or more reinforcement components extending width-wise relative to the cover. ### Claim 6 (depends on 5) The cover shield system according to claim 5, wherein the reinforcement components are bars provided at intervals along the length of the cover. ### Claim 7 (depends on 1) The cover shield system according to claim 1, wherein the cover further comprises one or more connecting members proximal to one or more longitudinal edges of the cover for interconnection between the cover and the telescoping portion of the conveyor system. ### Claim 8 (depends on 7) The cover shield system according to claim 7, wherein said one or more connecting members are a plurality of magnetic elements attached to the cover. ### Claim 9 (depends on 1) The cover shield system according to claim 1, wherein said shuttle assembly comprises a rollup barrel configured to rotate during the extension and retraction of the cover, and to receive and retain the cover during storage. ### Claim 10 (depends on 9) The cover shield system according to claim 9, wherein said rollup barrel is biased via a passive biasing mechanism or an active biasing mechanism. ### Claim 11 (depends on 10) The cover shield system according to claim 10, wherein said biasing mechanism is configured to provide an adjustable level of bias. ### Claim 12 (depends on 11) The cover shield system according to claim 11, wherein said biasing mechanism comprises a clock spring and an adjustment shaft connected to the clock spring for adjusting the bias by rotation of the adjustment shaft. ### Claim 13 (depends on 12) The cover shield system according to claim 12, wherein said adjustment shaft further includes a locking position to effectively disengage the biasing mechanism from the cover. ### Claim 14 (depends on 1) The cover shield system according to claim 1, further comprising a brake to inhibit extension of the cover from the shuttle assembly. ### Claim 15 (depends on 1) The cover shield system according to claim 1, wherein the shuttle assembly further comprises an idler roller positioned overtop of the cover and configured to press the cover toward to the perimeter of the conveyor system. ### Claim 16 (depends on 1) The cover shield system according to claim 1, wherein the shuttle assembly further comprises a lower shield positioned proximate to an aperture for receiving the cover into the shuttle assembly, the lower shield connected to the shuttle assembly in a rotatable configuration. ### Claim 17 A telescoping conveyor system comprising: a base portion and a telescoping portion each comprising a respective conveyor; a cover extendable and retractable along the length of the telescoping portion, said cover formed from a flexible material and configured to substantially span the width of the telescoping portion, said cover having a free end connected to the conveyor system at a first location; and a shuttle assembly biased to retract the cover for storage, said shuttle assembly being movably mounted to the telescoping portion of the conveyor system to allow relative movement between the shuttle assembly and the telescoping portion in a direction parallel to the length of the telescoping portion, wherein said shuttle assembly is anchored to the base portion at least during extension of the telescoping portion. ### Claim 18 (depends on 17) The telescoping conveyor system according to claim 17, wherein said shuttle assembly is mounted to the telescoping portion using a slidable mount or a rolling mount, and wherein the telescoping portion comprises a track or rail for operative coupling with the slidable mount or the rolling mount. ### Claim 19 (depends on 17) The telescoping conveyor system according to claim 17, wherein the cover further comprises one or more magnets proximal to one or more longitudinal edges of the cover for interconnection between the cover and the telescoping portion of the conveyor system. ### Claim 20 (depends on 17) The telescoping conveyor system according to claim 17, wherein said shuttle assembly comprises a rollup barrel configured to rotate during the extension and retraction of the cover, and to receive and retain the cover during storage. ### Claim 21 (depends on 17) The telescoping conveyor system according to claim 17, wherein the shuttle assembly further comprises an idler roller positioned overtop of the cover and configured to press the cover toward to the perimeter of the conveyor system.
