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.

An articular pole assembly comprising: an articular pole which is 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 pivotally mounted therebetween, 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 releaseably engaged with notches in said side plates and in the side plates of the adjacent unit block member and a spring urging the bent projections of the connecting plate to push towards the notches of the side plates; and a take-up casing having a desired shape for the take-up of the pole in a curved state, the take-up casing having cam portions co-acting with said bent portions for disengaging the bent projections from the notches against the resilient action of the spring so as to make the unit block member rotatable about the pins, whereby the unit block members can be accommodated in a curved state in the casing.
