In one embodiment, a closure system comprises a guide assembly having a channel defined by a first guide wall and a second guide wall. The closure system may include a retention bar extending into the channel from the first guide wall and a plurality of slats. Each slat of the plurality of slats may be configured to interlock with another of the plurality of slats. Each slat may have a retention groove with at least one sidewall configured and dimensioned to engage the retention bar to retain the slat within the channel.

A roller-shutter door system comprises a pair of opposed substantially parallel guide rails and a door formed by longitudinally hinged door slats coupled to a retraction roller. The door can be opened and closed with rotation of the retraction roller, and longitudinal ends of the door slats ride within door guide channels in the guide rails. Exterior side seals may cover a gap between the door slats and the door guide channels, and wear shields may be interposed between coated exterior surfaces of the door slats and the side seals so that the side seals bear on the wear shields instead of the coated exterior surfaces. The guide rails may have equipment channels on interior sides thereof, and radius guides may be releasably received in open superior ends of the equipment channels. The radius guides have outwardly facing guide surfaces to guide the door slats toward the retraction roller.

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 container inspection device and a container inspection method for inspecting containers are provided. The container inspection device comprises at least one light fixture for illuminating containers at a predetermined inspection instant of time for inspecting the containers, and an electrical line for connecting the at least one light fixture to an electrical energy supply and to a bus system, so that the electrical line serves both to supply the at least one light fixture with electrical energy and to connect with a real time data network.

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 conveyor belt for conveying articles along a conveyor path comprises a plurality of slat members disposed parallel to each other and disposed transversely with respect to the conveyor path, wherein leading and trailing edge portions of the slat members are angled downwardly with respect to the conveying surface upon which articles being conveyed are supported so as to prevent edge portions of the articles being conveyed from being interposed between the leading and trailing edge portions of the slat members so as not to be pinched by adjacent ones of the leading and trailing edge portions of adjacent slat members.

A modular component including an elongate hollow body having first and second attaching elements for attaching the modular component to another modular component. The first attaching element is in the form of cylindrical shaped spigot extending along an external surface of a first side wall of the body. The second attaching element is in the form of socket extending along an external surface of a second side wall of the body directly opposite the spigot. The socket has an internal shape that is sized and of a complementary shape of the spigot for receiving a spigot of another modular component. The socket is connected to the spigot by one or more bracing members that extend in a direction from the first side towards the second side between the spigot and the socket.

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 rollable device for occluding an opening of a residential building, includes a frame mounted in the opening and provided with at least two lateral guiding slides with a U-shaped cross-section, in order to define a general closure plane, and a set of transverse slats hinging relative to each other in pairs by the respective longitudinal edges thereof, the slats sliding within the two slides between a first inactive raised position in which the slats are wound about an upper transverse axis and a second active lowered position in which the slats are unwound and form an apron for closing the opening. The cross-section of the lateral slides is greater than the thickness of the slats and in the second active lowered position, the slats adopt a vertical accordion configuration in the lateral slides and form, relative to each other in pairs, an angle other than 180?.

A slat for use in a rolling shutter is provided. The slat comprises a engaging track located at a first edge of a body and a receiving track located at a second edge of the body. Illustratively, the engaging track has a hook-shaped profile, and the receiving track comprises a lip member and a guard member defining a space adapted to receive therein an engaging track of an adjacent slat. The engaging track and the receiving track are designed to minimize the space required for the rolling shutter to be retracted around a spindle.
