摘要:
A blind slat (1) has a substantially constant cross-sectional profile extending between a leading end (2) and a trailing end (3). The profile defines an upper face (4) of the slat (1). The upper face (4) has a convex portion (6) extending from adjacent the leading end (2) towards the trailing end (3). The convex portion (6) has an apex (7) at which the upper face (4) is parallel to a reference axis (R) of the profile that extends laterally between the leading end (2) and the trailing end (3). The upper face (4) also has a concave portion (8) located between the convex portion (6) and the trailing end (3). The concave portion (8) has a base (9) at which the upper face (4) is parallel to the reference axis (R). An inflection (10) joins the convex portion (6) and the concave portion (8). The upper face (4) is inclined with respect to the reference axis (R) by at least 11° at the inflection (10). The profile has a depth measured between the leading end (2) and the trailing end (3) of between 105 and 150 mm.

Das Halteband (1) zum Halten von Lamellen eines Behangs, umfasst ein Metallband (3) mit Halteteilen (5), die mittels je eines Niets (7) verdrehsicher mit dem Metallband (3) verbunden sind.
摘要:
The invention relates to lift and tilt mechanisms for a Venetian blind comprising a plurality of parallel elongated slats (2) and pairs of tilt and lift cords (19, 20), where the lift and tilt mechanisms (30) comprise a tubular member (36) mounted for rotation with and axial displacement over a drive shaft (33) and guide means (46) for maintaining the lift cords (20) in their proper axial position and for directing the lift cords (20) to the outer circumferential surface of said tubular member (36), whereby the lift cords (20) upon rotation of said tubular member (36) will become helically wound on or off the circumferential surface of the tubular member (36) resulting in said slats (2) being raised or lowered as the tubular member (36) rotates. The invention furthermore relates to a Venetian blind comprising the above lift and tilt mechanism and slats designed designed to cover very large window openings.

Rafflamellenstore (1), bei dem die Lamellen (2) an ihren Längsseiten über Gelenkverbindungen (3) mit Tragelementen (4), insbesondere Tragband oder Tragseil, verbunden sind, wobei wenigstens eine Gelenkverbindung (3) zwischen einem starr mit der Lamelle (2) verbundenen Halteelement (5) und einem mit dem Tragelement (4) fest verbundenen Befestigungselement (6) ausgebildet ist, wobei die Gelenkverbindung (3) ein Kugelgelenk (16) aufweist und die Gelenkpfanne (9) am mit dem Tragelement (4) starr verbundenen Befestigungselement (6) ausgebildet ist.
摘要:
Die Lamelle weist eine konvexe Vorderseite (12) und eine konkave Rückseite (13) sowie wenigstens eine Öffnung (10) für den Durchgang eines Aufzugsorgans (4) und wenigstens zwei im Abstand zueinander angeordnete Öffnungen (8) für den Durchgang jeweils eines Führungsseils (3) auf. Die Öffnungen (8) für den Durchgang der Führungsseile (3) sind jeweils im Grund einer auf der Rückseite (13) vorstehenden Prägung (7) angeordnet. Eine Store (1) aus solchen Lamellen (2) zeichnet sich durch einen besonders kleinen Transmissionsgrad und eine hohe Stabilität aus.
摘要:
A pleated blind 20 is disclosed including a head rail 22, a bottom rail 24 and an expandable and collapsible shade 28 extending between them and divided up into a plurality of pleats 30 by fold lines 32. A row of apertures 42 passes through each pleat 30 to permit passage of a supporting cord 10. The supporting cord 10 consists of a central yarn 12 and a series of equally spaced polymeric rungs 14. The rungs 14 are spaced at equal intervals along the cord 10, the spacing between the rungs 14 being substantially equal to the maximum distance between the head rail 22 and the bottom rail 24 divided by the number of pleats 30 in the shade 28. In this way, the rungs 14, which are of sufficient length to span the sides of the apertures 42, will support their respective pleats 30 and prevent the pleats from opening up too widely, thus ensuring that the pleat spacing remains substantially even.
摘要:
A tape spacer for securing the ladder tape of a venetian blind slat of a given width. It includes a body (10) having a length slightly greater than the width of the slat. A single hook (16) is provided on one end and two laterally spaced hooks (20 and 24) on the other end. The body is angled to position these loosely adjacent the edges and the handle (28) is then operated to spring the third hook (24) over the other edge of the slat.
摘要:
Venetian blind ladder means are provided in which first and second cross elements (4,5) of each cross connections of the ladder are located whereby the height of the projection of every pair of elements on a plane through the longitudinal side member axes ranges between zero and slightly larger than the depth of the blind slat material and the distance between the side members (3a,3b) of the ladder is only slightly greater than the slat width. During assembly, the ladder means are guided so that, at the location of interlacing, each consecutive interlacing opening is angled to extend in a plane perpendicular to the plane of slat feed or at an angle so that the projection of the mutual spacing between elements (4,5) is this perpendicular plane is sufficiently large to allow the advancing slat (2) to be easily and rapidly fed therethrough.
