Abstract
A telescopic mast system includes a telescopic mast comprising a plurality of telescopic mast sections and a drive mechanism for extending and retracting the telescopic mast sections. The drive mechanism includes a rigid chain having one end connected to a last one of the telescopic mast sections to move the telescopic mast sections and a plurality of guide plates cooperating with the telescopic mast sections to prevent buckling of the rigid chain.
Claims20
A telescopic mast system comprising:
- a telescopic mast comprising a plurality of telescopic mast sections;
- and
- a drive mechanism for extending and retracting said telescopic mast sections, said drive mechanism including a rigid chain having one end connected to a last one of said telescopic mast sections to move said telescopic mast sections and a plurality of guide plates cooperating with said telescopic mast sections to prevent buckling of said rigid chain.
A telescopic mast system as set forth in claim 3 wherein said guide plates include an aperture to allow said rigid chain to extend therethrough, wherein said rigid chain is attached to said guide plate of the last one of said telescopic mast sections.
A telescopic mast system comprising:
- a telescopic mast comprising a plurality of telescopic mast sections;
- a mounting mechanism to rigidly attach a first one of said telescopic mast sections to a support surface;
- and
- a drive mechanism for extending and retracting said telescopic mast sections, said drive mechanism including a rigid chain having one end connected to a last one of said telescopic mast sections, at least one rotatable driving pinion engaging said rigid chain, a shaft attached to said at least one driving pinion, a motor for rotating said shaft to move said rigid chain, and a plurality of guide plates cooperating with said telescopic mast sections to prevent buckling of said rigid chain.
A telescopic mast system comprising:
- a telescopic mast comprising a plurality of telescopic mast sections;
- a rigid chain disposed inside said telescopic mast and connected to a last one of said telescopic mast sections;
- a chain magazine for containing said rigid chain when said telescopic mast is retracted;
- a plurality of guide plates, one of said guide plates at a bottom of one of said telescopic mast sections, wherein said guide plates include an aperture to allow said rigid chain to extend therethrough, wherein said rigid chain is attached to said guide plate of a last of said telescopic mast sections;
- and
- a cable assembly for connection to the object.
