Patent ID: 8789550

Claim:
A modular system comprising a plurality of shaft segments, wherein at least two of the plurality of shaft segments have lengths which are a predetermined length, wherein each shaft segment comprises a shaft, an inserting end, and a receiving end, wherein each receiving end has a partially enclosed channel, wherein each inserting end has a protrusion which is configured to connect with a corresponding partially enclosed channel of another shaft segment to form a configuration attachment, wherein said partially enclosed channel has predetermined channel width, wherein said partially enclosed channel has a narrow neck which locks said protrusion in said channel, the narrow neck having a predetermined neck width which is less than the channel width, wherein the narrow neck increases the amount of force required for the protrusion to pass through the channel, and wherein the inserting end is inserted into the receiving end and said protrusion is passed past said narrow neck to lock the attachment, whereby the shaft segments are configurable into a plurality of segmented shafts to provide a support structure, each segmented shaft comprising a plurality of shaft segments coupled together by having the inserting end of one shaft segment removably coupled with the corresponding receiving end of another shaft segment to form the segmented shafts.
