The cover is easily engageable by being pushed over a folded vane bottom end that could enclose a weight whereby the vane material stretches through the cover and out through a slit. The cover versions are especially designed for do-it-yourself purposes and concentrate on ease of assembling and vane length adjustment.

Abstract: An apparatus and a method for assembling the slats of a venetian blind in which slats are fed in turn into the venetian blind ladders and are raised to a first position sequentially to form, at that first position, a stack of assembled slats. The length of stroke of the lifting mechanism, preferably a linear motor, is restrained by an abutment which is removed as the last slat of a stack is being lifted, so that the whole stack is then lifted to a higher position at which it is retained and the ladders are moved past the slat feed point so that no slats are inserted therein. The next stack of slats is then formed at the first position and before it is completed, the ladder means are cut between the first and second positions.

Abstract: A unit for positioning a venetian blind ladder tape and for guiding the slats of a blind between individual rungs of a rung pair of a ladder tape, said unit comprising two body portions, a guiding member on each body portion, each guiding member locating, for movement longitudinally of the guiding member, one of the side tapes of the ladder tape and permitting the rungs to extend to the other side tape, the body portions being resiliently urged apart by a spring to tension the rungs. Each body portion carries a slat guide element which is positioned to feed slat material between the rungs of a pair and a resiliently retractable abutment plate is located adjacent each slat guide element, so as to engage the rung of a pair nearer thereto. The ladder tape is fed intermittently forward and is urged rearwardly between intermittent advances by spring-urged parts, so that the nearer rung of a pair is engaged against the abutment.

Abstract: A tilting roll and tilting roll assembly for the ladder means of a venetian blind for the ladder cord or tape of a venetian blind in which the roll which is rotatable within a base about the longitudinal axis of the roll includes a first pair of opening portions which are circumferentially spaced from one another, one cord or tape of the ladder passing over the top of the roll into engagement with one of the opening portions and the other tape or cord passing over the top of the roll from the other side and engaging the other opening portion. A second pair of opening portions is provided axially spaced from the first to enable the ladder tape or cord to be mounted on the opposite side of a lift cord.

Abstract: A clip for mounting a wall or ceiling panel structure having a plurality of panels in which the panels have inturned rims on their longitudinal edges and preferably beads on the rims. The clip has a body having downwardly extending first members preferably adjacent one edge and a downwardly extending fourth member preferably adjacent an opposite edge.A second downwardly extending member having lateral lugs is adjacent and spaced from the first member by an amount to accommodate two rims. A pair of third downwardly extending members is shaped to enable two panels to be spaced from one another and is also provided with a lug so that the clip may alternatively be used for mounting a panel adjacent a wall surface.

Abstract: A mechanism for the roller of a roller blind, in which a housing has rotatably mounted therein a pulley over which a ball cord, passes, with two pieces of cord hanging down, one from each side of the pulley. The balls of the ball cord can be engaged in one of two U-shaped slots, to lock the cord. The U-shaped slots are each formed in a locking element which is designed as a component which can be fastened to the housing in either of two different positions, the locking part being arranged on the locking element in such a way that, in one or other of the two different positions, it always interacts with one or the other of the pieces of cord hanging down.

Abstract: A suspended ceiling, and components therefor, are described in which a carrying structure, for example in the form of carriers arranged in a grid, have depending therefrom a number of suspension units and a slat assembly, which may have decoratively disposed slats thereon, is mounted on each suspension unit. The arrangement is such that the slat assemblies are capable of at least limited rotation between a number of different positions, the slat assemblies being restrained in each position so that each slat assembly may have its orientation relative to its neighboring slat assemblies varied. This arrangement enables one to produce a very different visual effect simply by rotating certain of the slat assemblies relative to their neighbors. The specification discloses a number of different forms of slat assembly.
