Abstract
A conveyor apparatus comprising a base frame and an extendable frame, where the extendable frame is supported within the base frame and a drive assembly. The drive assembly comprises a rotatable drive mechanism which has a plurality of frame engaging portions which are arranged to engage with a plurality of drive engaging portions disposed upon a first one of the base or extendable frames such that when the drive mechanism rotates, the drive assembly is configured to displace the first one of the base or extendable frames with respect to the first between an extended state and a retracted state.
Claims19
A conveyor apparatus comprising:
- a base frame and an extendable frame, wherein the extendable frame is supported by, and within, the base frame;
- a drive assembly;
- wherein the drive assembly comprises a rotatable drive mechanism having a plurality of frame engaging portions which are arranged to engage with a plurality of drive engaging portions provided on a first one of the base or extendable frames so that when the rotatable drive mechanism rotates, the drive assembly is configured to displace the first one of the base or extendable frames with respect to a second one of the base or extendable frames between an extended state and a retracted state;
- wherein the plurality of drive engaging portions comprise a plurality of formations;
- and
- wherein the rotatable drive mechanism comprises first and second sprockets that are spaced apart to define a gap therebetween which is suitable for receiving one or more of the plurality of drive engaging portions, connected by the plurality of frame engaging portions which extend between the first and second sprockets.
A drive assembly for a conveyor apparatus having a base frame and an extendable frame, the extendable frame having a plurality of drive engaging portions disposed thereon, the drive assembly comprising:
- a rotatable drive mechanism having a plurality of frame engaging portions which are arranged to engage with the plurality of drive engaging portions provided on the extendable frame so that when the rotatable drive mechanism rotates, the drive assembly is configured to displace the extendable frame with respect to the base frame between an extended state and a retracted state;
- wherein the plurality of drive engaging portions comprise a plurality of formations;
- and
- wherein the rotatable drive mechanism comprises first and second spaced sprockets that are spaced apart to define a gap therebetween which is suitable for receiving one or more of the plurality of drive engaging portions, connected by the plurality of frame engaging portions which extend between the first and second sprockets.
A conveyor apparatus comprising;
- a base frame and an extendable frame, wherein the extendable frame is supported by, and within, the base frame;
- a drive assembly comprising a rotatable drive mechanism having a plurality of frame engaging portions which are arranged to engage with a plurality of drive engaging portions provided on the extendable frame so that when the drive mechanism rotates, the drive assembly is configured to displace the extendable frame with respect to the base frame between an extended state and a retracted state;
- wherein the extendable frame comprises a plurality of parts, or modules, which are pivotably coupled together;
- and
- wherein the extendable frame is configured so that when the extendable frame adopts the extended state the one or more parts of the extendable frame are configurable to pivot relative to one or more other parts of the extendable frame so that the extendable frame assumes a substantially curved configuration.
