摘要:
A composite structure such as a roller door comprises a plurality of rigid slats (1) arranged parallel with one another and spaced apart transversely in an array, the array of slats being sandwiched between upper (3) and lower (4) flexible sheets fixed together in the spaces (5) between adjacent slats to form flexible hinge portions. Preferably the structure is formed by advancing the array of slats (1), in the longitudinal direction of the slats through means which applies the upper and lower flexible sheets to the upper and lower surfaces of the slats and bonds the flexible sheets to the upper and lower surfaces of the slats, then passing the resulting assembly, still in the longitudinal direction of the slats, through apparatus which bears on the flexible sheets and deforms them, in the interstices between the slats, until the upper and lower sheets come together in said interstices and are bonded to each other where they come together. Thus, the slats are securely encapsulated between the flexible sheets and the portion of the flexible sheets between adjacent slats form said flexible hinge portions.

A slatted curtain for roller blinds has slats (1, 2, 3) which are made of compressed or cast wood and into which a carrier element (4, 5, 6) is pressed or cast. The carrier elements (4, 5, 6) have hook-shaped joint portions (7, 8) for interconnecting the slats (1, 2, 3).

A door panel for an overhead roll-up door assembly having a first face, a second face, a top edge, and a bottom edge. The door panel is constructed by butt jointing at least two sub-panels together in a horizontal direction such that neither sub-panel overlaps the other and applying at least one strip of seaming material over each horizontal butt joint, the seaming material being adhered over each butt joint on at least the first face of the door panel. The door panel further includes at least one strip of seaming material adhered vertically along at least one face of the door panel extending from approximately the top edge of the door panel to approximately the bottom edge of the door panel, and being configured such that a top face of the vertical seaming material is substantially co-planar with a top face of the horizontal seaming material.

To insulate a window, the bottoms, the ends and a portion of the tops near the ends of a plurality of relatively-thick, relatively-stiff polyurethane strips are cemented to a flexible fabric by an elastomer. The maximum width of the polyurethane strips increases with their position along the fabric as the square root of a function of the stretching ability of the elastomeric cement and the radius from the center of the roller to the strip. That function includes the difference between the square of a first quantity and a second quantity, the first quantity being the sum of the radius of the particular rolled end and the stretching ability of the elastomer at the edge of the strip and the second quantity being the radius squared. The uppermost polyurethane strip forms a sealing engagement with the sill, the two sides of the backing and the ends of the strips ride in sealing tracks and the bottom strip rests on the sill to form a compartment with the window.

The invention relates to a shutter device co-operating with driving means enabling the shutter (1) to be displaced between an open position and a closed position, this shutter (1) being guided by a guide track (4, 5) and being designed to close off a bay (6) or other opening, this device comprising a drum (8) about which the shutter (1) is wound when the latter is in the open position forming a roll (31) made up of turns formed by successive layers of the shutter (1), and from which the shutter (1) can be unwound into its closed position, confining means being provided to prevent the turns from forming wrinkles as the shutter (1) is being displaced into the closed position and/or to prevent these turns from slipping relative to one another.

The invention relates to a roller shutter for opening and closing a doorway (12) having a door blade (11), the door blade (11) comprises several rigid shutter elements (13) which are hinged with each other, the shutter elements (13) are guided by side rails (18) at opposed sides of the doorway (12), wherein each shutter element (13) provides an end piece (19) at each horizontally spaced end of the shutter element (13) for spacing layers of rolled up shutter elements (13) apart from each other, each end piece (19) has at least one concave section (27) for coiling the end pieces (19) on a coiling device (14) and/or in layers on top of each other. For reducing the risk of weakening a connection between the end piece (19) and the shutter element (13), for reducing noise and/or vibrations during the opening and/or closing of the door way and/or to increase the stability of the roller shutter the roller shutter (10) is characterized in that at least some of the end pieces (19) having at least one plane gliding section (28), the plane gliding section (28) is arranged for interacting with a slide guide (36) of the side rail (18) for leading the end pieces (19) into and/or out of the side rails (18).
