A slat for a rolling shutter is provided that is formed as a single walled, continuous bent sheet. The slat includes a body having a hook-shaped engaging track at a first end, and a receiving track at the second end comprising a guard member and a hook-shaped lip member that form a pocket for receiving the engaging track of another slat. The guard member includes a portion of the sheet that is bent over on itself. The lip member extends from the guard member, and is spaced apart from the guard member to define an aperture that is sized and shaped to receive the engaging track of the other slat.

A slatted door includes a plurality of interengaged slats, and end members arranged at ends of respective slats. The end members and the slats are configured and arranged so that, when the slats are engaged with one another and with respective end members, at least one lateral reinforcement impact distribution structure is formed. The impact distribution structure is configured to absorb, distribute and/or redirect impact force in a direction along the length of the slats.

A locking system for a rolling shutter that includes a plurality of rolling shutter slats, comprises a guide track with a U-shaped guide channel having a channel base, and first and second channel walls. A lock bar is coupled to the rolling shutter slats. In a locked position, the lock bar extends transverse to the channel base. The lock bar has a notch covered by a breakaway wall that is aligned with the channel base in the locked position. The lock bar may be slidably received in a sleeve that is positioned in the guide channel to increase resistance to torsional forces on the locking system. In an alternative embodiment, the locking system comprises a unitary extruded body, a lock bar, and a handle. A longitudinal channel is formed integrally in the body for receiving the lock bar and handle. The lock bar is slidable in the channel between an extended locked position and a retracted unlocked position. The handle is positioned in the channel to stop the retraction of the lock bar at the unlocked position.

A utility slat for a rolling shutter comprises a single-walled slat body with a U-shaped channel formed in the slat body that defines an interior space for receiving additional features, such as a rolling shutter locking device. A cover is removably coupled to the slat body to enclose the interior space.

A rolling shutter comprises first and second slats, each slat having inner and outer sides, a first edge with an engaging track, and a second edge with a receiving track. The receiving track comprises a lip member and a guard member that are spaced apart to form an aperture that is sized and shaped to receive the engaging track of another slat. The engaging track of the first slat is received in the receiving track of the second slat to form an articulating hinge. The hinge has a vertical position with the maximum extension of the first and second slats, and the hinge is rotatable from the vertical position in a backward direction. In one embodiment, the engaging track is hook-shaped and comprises a bend that curves toward the inner side, and a rib positioned at the first edge that projects from the inner side. The hinge is rotatable from the vertical position in the forward direction, and the rib of the first slat contacts the lip member of the second slat to stop the forward rotation of the hinge.

A shutter roller door with a shutter roller drivable by a drive mechanism; a flexible door windable on the roller and movable between retracted and extended positions by the drive mechanism, the door having integrally formed interconnected slats, each having upper and lower edges, and arranged perpendicular to a direction of door travel; a guide rail assembly positioned at each side; and end members attachable to an end of a corresponding slat. Each slat has an upper hook portion and an upper curved channel, the upper hook portion configured to engage with a lower curved channel of the lower edge of an upper adjacent slat, and the lower edge having a lower hook portion and a lower curved channel configured to engage with the upper curved channel of the upper edge of a lower adjacent slat.

A slat for a rolling shutter is provided that is formed as a single walled, continuous bent sheet. The slat includes a body having a hook-shaped engaging track at a first end, and a receiving track at the second end comprising a guard member and a hook-shaped lip member that form a pocket for receiving the engaging track of another slat. The guard member includes a portion of the sheet that is bent over on itself. The lip member extends from the guard member, and is spaced apart from the guard member to define an aperture that is sized and shaped to receive the engaging track of the other slat.

A slat for roller shutters includes an internally hollow elongated body extending along a longitudinal direction with a first face and opposite second face, designed to turn respectively towards the outside and inside of the compartment closed by the shutter. A cavity along a first longitudinal edge of the body is delimited by a first appendage on the first face, and a second appendage on the second face. A coupling appendage extends from a second longitudinal edge. Two recesses are at ends of the second longitudinal edge. Two notches on the second appendage near the opposite ends extend transverse to the first longitudinal edge, and define, on the second appendage, first and second tabs at opposite ends of the body. Each tab bends against the first appendage to close the coupling cavity at the ends of the body. The first appendage extends continuously from one end of the body.

A pet door system is provided including a casing configured to attach the pet door system to a building and a flexible door attached to the casing. In some embodiments, the door is segmented and comprises a plurality of interlocking segments that are rotatable with respect to each other. In some embodiments, the pet door system further includes a rotating cylinder attached to the flexible door and rotatably connected to the casing and a motor comprising a gear head, where the gear head is attached to the rotating cylinder, such that when the motor is activated, the gear head is rotatable in a first direction to wind the flexible door around the rotating cylinder. In some embodiments, the pet door system may be operated by a pet-worn collar and/or may be remotely controlled via a mobile device.

A base slat pry stopper, such as a base slat locking bracket, for locking a rolling shutter curtain covering an opening of a structure is disclosed. The base slat pry stopper may include a bracket base plate mounted to an opening bottom wall on an interior side of the shutter curtain, and a base slat engagement portion extending upward from the bracket base plate and above a top surface of the opening bottom wall. When the shutter curtain is unrolled to cover the opening, the base slat engagement portion engages the base slat to prevent the base slat from deflecting upward away from the opening bottom wall when a force applied from an exterior side of the shutter curtain causes the base slat to deflect toward the interior side of the structure and the shutter curtain. The base slat pry stopper may be permanently or removably installed.
