Abstract
A shutter of the type used as a closure for boxes or containers, or for garage doors, includes a series of interconnected elongated strips having at each end of each strip an integral male and female connecting member so that the female connecting members of one strip are capable of interlocking with the male members of an adjacent strip to form the shutter. Each strip also includes an elongated recessed area and a corresponding overlapping portion positioned below the recessed area. When a series of strips are interconnected to form the shutter, the overlapping portion of one strip is received in the recess portion of an adjacent strip. Lastly, each strip includes at least one vertically oriented pair of tongue and groove members positioned intermediate the ends of each strip so that when a series of strips are interconnected to form a shutter, the tongue of one strip is received by the groove of a corresponding strip so as to prevent tampering. The strips can be injection molded from plastic material and can include metal reinforcement members extending longitudinally within the strip.
