Abstract
A multiple-glazed window assembly is described in which a tilting mechanism unit (40) is secured to one side frame member (10). A venetian blind assembly including upper and lower supporting members (31, 32) is mounted on carriers (14,15) carried by the upper and lower frame members (12,13) by snap-fit pivotal securing elements (25) and connecting means (75) on the upper and lower supporting elements (31,32) are advanced to engage connecting means (58) on the tilting mechanism unit (40).
Claims26
A slat tilting mechanism unit for use in mounting a venetian blind in a mounted position between two panes of glass (16, 17) of a multiple glazed window forming an opening to be covered by said blind, in which the blind comprises an upper elongate supporting member (31) extending across all or part of the width of the blind, means (25) for pivotally mounting the supporting member about its logitudinal axis, slat supporting means (33) extending from said upper supporting member (31) and a plurality of slats (34) having slat ends carried by said supporting means (33), said slat tilting mechanism unit being characterised in that it is separate from the blind and includes an elongate body (40) positionable at a side of the opening to be covered by the blind, so as to confront the slat ends at one side of the mounted position of the blind, a bearing (46) on said body (4), adjacent one end of the body, a rotatable drive member (53) mounted in said bearing (46), an operating member (64-67) linearly movable longitudinally of said body under magnetic effect by a linearly movable actuating member (69) mounted externally of the multiple glazed window, a drive element (61) connected between said operating member and said rotatable drive member (53), whereby linear movement of said opertaing member (64-67) will cause simultaneous rotation of said drive member (53) in the same rotational sense, a connection (57, 58) on said rotatable drive member (53) drivingly connectable, to one end of the upper elongate supporting member (31).
A mechanism unit according to any preceding claim, characterised in that said drive element (61) is a flexible metal drive band, in that the drive member or members (53) are provided with an at least part circular surface (54) over which said flexible element (61) passes and in that the flexible metal band is provided with at least one aperture (62) or projection on a portion thereof, passing over each at least partly circular surface (54), said surface being provided with projections (55) or recesses to engage with said aperture (62) or projections respectively.
A method of mounting a tiltable venetian blind between two panes of a multiple glazed window having a rectangular frame with upper and lower frame members and side frame members, characterised in that it comprises the steps of mounting during the window assembly operation, a separate venetian blind tilting mechanism unit against one of the window frame side members, positioning holding means to hold the unit fixedly in close contact with said side member, mounting a pre-assembled venetian blind slat assembly comprising slat support members, slat supporting means, a plurality of slats and connecting means, to at least the upper-one of the upper and lower frame members, and coupling the slat assembly to the tilting mechanism unit by interconnecting them with the connecting means and in a manner in which activating the tilting mechanism from outside the window will result in the tilting of the slats.
A venetian blind assembly according to clsaim 21, characterized in that the means for pivotally mounting at least one of the upper and the lower supporting member comprise bearing clips (25), said bearing clips (25) each including a pivot bearing (27,28) for the respective supporting member and a securing element (3) which is engageable by a snap-fit connection in a receiving portion of a carrier (14,15) forming the respective frame (12,13) of the multiglazed window.
A slat tilting mechanism unit for use in mounting a venetian blind between two panes of glass (16,17) of a multiple glazed window, in which the blind comprises an upper elongated supporting member (31) extending across all or part of the width of the blind, means (25) for pivotally mounting the supporting member about its longitudinal axis, slat supporting means (33) extending from said upper supporting member (31) and a pluraity of slats (34) carried by said supporting means (33), said slat tilting mechanism unit being characterized in that it is separte from the blind and includes an elongate body (40) a bearing (46) on said body (40), adjacent one end of the body, a rotatable drive member (53) mounted in said bearing (46), an operating member (64-67) linearly movable longitudinally of said body under magnetic effect by a linearly movable actuating member (69) mounted externally of the multiple glazed window, a drive element (61) connected between said operating member and said rotatable drive member (53), whereby linear movement of said operating member (64-67) will cause simultaneous rotation of said drive member (53) in the same rotational sense, a connection (57,58) on said rotatable drive member (53) drivingly connectable, to one end of the upper elongate supporting member (31).
A slat tilting mechanism unit for use in mounting a venetian blind within an opening to be covered thereby in which the blind comprises an upper elongate supporting member (31) extending across all or part of the width of blind, means (25) for pivotablly mounting the supporting member about its longitudinal axis, slat supporting means (33) extending from said upper supporting member (31) and a plurality of slats (34) carried by said supporting means (33), said slat tilting mechanism unit being characterised in that it is separate from the blind and includes an elongate body (40) securable against an inner surface of a side frame member of the opening to be covered by holding means (70), a bearing (46) on said body (40), adjacent one end of the body, a rotatable drive member (53) mounted in said bearing (46), an operating member (64-67) linearly movable longitudinally of said body by a linearly movable actuating member (69), a drive element (61) connected between said operating member and said rotatable drive member (53), whereby linear movement of said operating member (64-67) will cause simultaneous rotation of said drive member (53) in the same rotational sense, a connection (57, 58) on said rotatable drive member (53) drivingly connectable, to one end of the upper elongate supporting member (31).
