Abstract:
An extension system for use with a carpet stretching apparatus, the extension system comprising:an extender piece connectable to the carpet stretching apparatus, the extender piece having at least three tubular rod members rigidly connected to each other by struts to form a truss structure wherein at least one of the tubular rod members lies outside of a plane containing the other two tubular rod members, the truss structure having an axis therethrough,the struts connecting any two of the tubular rod members lying substantially in a plane containing the two tubular rod members,the tubular rod members being spaced radially from the axis,the tubular rod members being disposed in parallel relationship to each other and to the axis, and whereinthe extender piece has a first and a second end thereon,an outer support tube supported in substantially rigid relationship from the tubular rod members adjacent to the first end of the extender piece,an elongated inner tube slidably disposed within the outer support tube in a direction parallel to the axis of the truss structure, the elongated inner tube having a free end and an inner end. The elongated inner tube being telescopically receivable within the truss structure,the elongated inner tube being securable in fixed relationship to the outer support tube at any of a predetermined plurality axial locations along the elongated inner tube thereby to adjust the distance from the free end of the elongated inner tube to the second end of the extender piece.
