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.

In an example an overhead door track is provided. The overhead door track includes a vertical track section having an opening to receive a roller of a panel of an overhead door and to guide movement of the roller within the opening and a single solid polymer based vibration isolator coupled to the vertical track section to reduce vibration of the vertical track section caused by movement of the roller within the opening.

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 slat system having a slat hanging with slats and a shifting apparatus for shifting the slats. The slats are intercoupled and movable from a closed position, in which broad faces of the slats are substantially flush in a plane and narrow faces of adjacent slats face one another, into an open position, in which the broad faces of the slats are parallel to one another but not parallel to an opening and closing direction, using the shifting apparatus to shift the slats in the opening and closing direction. The shifting apparatus has a pulling means coupled at one end to the slat hanging. The slat system has a first sheave mounted so as to be rotatable about an axis in two directions, to which sheave the other end of the pulling means is fastened, and a locking means to block the sheave from rotating in the open position.
