ABSTRACT:
There is disclosed a new articular pole assembly capable of winding, which comprises an articular pole and a take-up casing having a desired shape for the take-up of the pole in a wound or curved state, the articular pole being composed of a continuous series of unit block members connected to one another, the unit block members each having a pair of side plates and a connecting plate, the side plates being connected to the corresponding side plates of the adjacent unit block member by a pin, the connecting plate having bent projections releasably engaged with notches of the side plates of the adjacent block member with the proviso that a spring is employed to urge the projections of the connecting plate to push towards the notches of the side plates, the take-up casing having cam portions for disengaging the projections from the notches against the resilient action of the spring so as to make the unit block member rotatable about the pin, whereby the continuous series of the unit block members can be accommodated in a wound state in the take-up casing.
