ABSTRACT:
The opposite, vertically elongated edges of a series of pivotly connected slats forming an accordion-type folding shutter are provided with integral tube-like connector members. One of the connector members is of a smaller diameter than the other to form an inner member which co-axially fits within the next adjacent outer member of the next slat. The inner members are connected to their respective slat edges by a narrow strip, extending the full length of their respective slats and arranged at an obtuse angle to the remainder of their slats, with the narrow members fitting through a slot in the adjacent outer member. The strip pivots within the slot of its outer member and engages beads integrally formed on the edges defining the slot in the outer member. The inner member is formed with a pair of radially outwardly extending beads, one of which engages one of the beads on the outer member when the slats are pivoted into their shutter extended position, thereby spacing the outer surface of the inner member from the inner surface of its outer member. The slat integrally joins its outer member along a plane which is tangent to the outer surface of the outer member, so that the extended adjacent pair of slats form a roughly 90 degree angle triangle when the shutter is extended.
