Abstract
Abstract A venetian blind assembly having a plurality of slats supported by two slat support means. The assembly is adapted to be connected at opposite ends extending parallel to the slats to fixed frame members. Each slat support means includes a longitudinal side member having means to support the slats. Resilient means are provided for imparting tension into all of the longitudinal side members during tilting of the slats whereby the blind assembly may be oriented in a number of different positions including inclined and horizontal positions without sagging.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
99 words
A venetian blind assembly comprising a plurality of slats (6) wherein the assembly is adapted to be connected at opposite ends extending parallel to the slats, to fixed frame members (2,3) at least two slat support means (7,8) for individually tiltably supporting said slats with each slat support means comprising two longitudinal side members (9,10,11,12) including means (13) to support said slats, and slat tilt means (16) connected to one end of said slat support means; characterized in having resilient means (31,32,55,62,70,71) for imparting tension in all of the longitudinal side members at least during tilting of the slats.
Claim 2
Dependent Claim
99 words
A venetian blind assembly comprising a plurality of slats (6) wherein the assembly is adapted to be connected at opposite ends extending parallel to the slats, to fixed frame members (2,3) at least two slat support means (7,8) for individually tiltably supporting said slats with each slat support means comprising two longitudinal side members (9,10,11,12) including means (13) to support said slats, and slat tilt means (16) connected to one end of said slat support means; characterized in having resilient means (31,32,55,62,70,71) for imparting tension in all of the longitudinal side members at least during tilting of the slats.
Claim 3
Dependent Claim
45 words
A venetian blind assembly according to claim 1 further characterized in that said two longitudinal side members (9,10,11,12) of a single support means (7,8) are interconnected and in that said resilient means e.g. a tension spring is operatively included in said two longitudinal side members.
Claim 4
Dependent Claim
69 words
A venetian blind assembly according to claim 1 further characterized in that the longitudinal side members (9,10,11,12) of each slat support means (7,8) are operatively connected together at the end of the assembly opposite said slat tilt means (16) and in that a single resilient means (55,62) operatively connects the longitudinal side members (9,10,11,12) of one slat support means with the longitudinal side members of another slat support means.
Claim 5
Dependent Claim
54 words
A venetian blind assembly according to claim 3 further characterized in having in addition a pulley (51,53) associated with each slat support means (7,8) and around which the longitudinal side members of the associated slat support means extend and in that said resilient means (55) connects the pulleys associated with each slat supporting means.
Claim 6
Dependent Claim
59 words
A venetian blind assembly according to claim 3 further characterized in having in addition a bracket (60,61) associated with each slat support means (7,8) and to which an end of the longitudinal side members (9,10,11,12) of the associated slat support means are connected and in that said resilient means (62) connects the brackets associated with each slat supporting means.
Claim 7
Dependent Claim
64 words
A venetian blind assembly according to claim 1 further characterized in that at least two longitudinal side members (9,12) on one side of the venetian blind assembly are operatively connected together by a first resilient means (70) and at least two longitudinal side members (10,11) on an opposite side of the venetian blind assembly are operatively connected together by a second resilient means (71).
Claim 8
Dependent Claim
56 words
A venetian blind assembly according to claim 1 further characterized in that the longitudinal side member (9,.10) of a slat supporting means (7) on one side of the venetian blind assembly is operatively connected to a longitudinal side member (11,12) of a further slat supporting means (8) on an opposite side of the venetian blind assembly.
Claim 9
Dependent Claim
57 words
A venetian blind assembly according to any one of the preceding claims further characterized in that each slat support means (7,8) comprises a tape ladder, in that each said longitudinal side member comprises a tape cable (9,10,11,12), and in that each said means to support said slats comprises at least one rung (13) extending between tape cables.
Claim 10
Dependent Claim
56 words
A venetian blind assembly according to claim 1 further characterized in having in addition a first headrail (15) mounting said slat tilt means adapted to be connected to a fixed frame member (2) and a second headrail (18) into which said resilient means are positioned adapted to be connected to a further fixed frame member (3).
Claim 11
Dependent Claim
62 words
A venetian blind assembly according to claim 9 further characterized in that one (18) of said headrails is detachably connected to a fixed frame member (3) and having in addition slat moving means (23) connecting said headrails (15,18) by which the detachably connected headrail (18) and slats may be moved towards the other headrail (15) on detachment from a fixed frame member.
Claim 12
Dependent Claim
40 words
A venetian blind assembly according to claim 10 further characterized in having a plurality of roller means (20,21) rotatably mounted in the headrail in which said resilient means are positioned and over each of which a longitudinal side member extends.
Claim 13
Dependent Claim
62 words
A venetian blind assembly according to claim 10 or 11 further characterized in that said slats (6) have support portions e.g. notches (27) cut in the end of a slat with one side of the notch extending along the tilt axis of the slat, at their ends adapted to slidably engage fixed side frame members (26,28) extending between said fixed frame members.
Claim 14
Dependent Claim
39 words
A venetian blind assembly according to claim 12 further characterized in that said headrail (18) detachably connected to a fixed frame member (3)having slide portions (25) on each end thereof adapted to slidably engage a fixed side frame member.
