Definitions

  • This invention relates to a venetian blind assembly having a plurality of slats and slat support means for individually supporting the slats where the slat support means include longitudinal side members.
  • ladder tapes which usually comprise parallel tape cables spaced a slat width apart and which are connected by cross ladders or rungs.
  • the tape cables are secured at their lower end to a bottom rail, which is connected to a fixed bottom frame member of an opening.
  • This arrangement however is not adaptable for use with inclined venetian blind assemblies or skylight assemblies which extend in a horizontal direction, since the tape ladders are usually slack and incapable of preventing the slats of the assembly from sagging.
  • a venetian blind assembly comprising a plurality of slats wherein the assembly is adapted to be connected, at opposite ends extending parallel to the slats, to fixed frame members, at least two slat support means for individually tiltably supporting said slats with each slat support means comprising two longitudinal side members including means to support said slats, and slat tilt means connected to one end of said slat support means; characterized in having resilient means for imparting tension in all of the longitudinal side members at least during tilting of the slats.
  • Such a venetian blind assembly is readily adaptable for use with skylights or in inclined openings as well as in venetian blind arrangements where the slats extend perpendicularly rather than horizontally as in the conventional blind constructions and when mounted is properly held in position and operable by way of a simple, easily mountable and operable arrangement. It may be conveniently moved across a skylight or inclined opening in order to provide convenient cleaning of the skylight or pane covering an inclined opening.
  • the slats may be supported by the longitudinal side members in all degrees of orientation including a horizontal position, as would occur when used to cover a skylight, or an inclined opening.
  • the blind assembly according to the invention may also be used in a vertical arrangement, that is where the longitudinal axes of the slats extend vertically, or in the more conventional hori2ontal arrangement wherethe plane of the assembly of slats is vertical and the longitudinal axes of the slats extend horizontally.
  • additional means are preferably included to either connect the slats fixedly to the side members or tape ladders, or to support the lower end of the slats.
  • each support means are operatively connected together and a resilient means, for example a tension spring, operatively connects the longitudinal side members of one slat support means to the longitudinal side members of another slat support means to impart tension in all the longitudinal members.
  • a resilient means for example a tension spring
  • the longitudinal members of one slat support means may be connected together and extend over a pulley which is connected by a resilient means to a further pulley over which the longitudinal side members of the other slat support means extend.
  • a further form of the invention involves having ends of two longitudinal side members of one slat support means connected to a bracket in turn connected by a resilient means to a further bracket connected to ends of the two longitudinal side members of the other slat support means.
  • a still further form of the invention involves having longtiduinal side members of one slat supporting means on both side of the assembly of slats each connected by a resilient means to a longitudinal side member of another slat supporting means and on the opposite side of the assembly of slats. In this manner, as well as in the previously described embodiments, tension is maintained constant in the longitudinal side member during all degrees of tilting of the slats by the slat tilt means.
  • the longitudinal side members on the same side of a blind assembly and of two slat supporting means are operatively connected together by a resilient means such that alternate tension exists between the longitudinal side members on one side of the blind assembly from the tension in the longitudinal side members on the other side of the blind assembly as occurs during tilting of the slats by the slat tilt means.
  • Tension still exists in all members during tilting but tension will vary depending on the degree of tilt.
  • the longitudinal side members each comprise a tape cable forming part of a tape ladder and the means supporting the slats comprise rungs extending between cables spaced apart a slat width.
  • the longitudinal side members could also comprise cables connected directly to the slats.
  • the slat tilt means are preferably contained within a first headrail adapted to be connected to a fixed frame member and the resilient means in a second headrail adapted to be connected to a further fixed frame member.
  • One of the headrails preferably but not necessarily the headrail containing the resilient means, is detachably connected to the fixed frame member in order that when disconnected, the headrail and plurality of slats may be moved towards the other headrail to allow cleaning of the skylight or pane covered by the blind assembly.
  • a slat moving means similar to a conventional slat lift means connects the two headrails.
  • the slats In order to prevent the detachable headrail and slats from falling when the detachable headrail is disconnected from its fixed frame member, the slats have support portions on each of their ends adapted to slide on fixed side frame members extending between the fixed end frame members which support portions preferably are in the form of notches in the ends of the slats with a side of the notch sliding on the side frame member extending along the tilt axis of the slat.
  • the detachable headrail also has slide portions adapted to slide on the same fixed side frame members to provide support for the rail when it is detached from its fixed end frame member.
  • the headrail containing the resilient means also may have a plurality of rollers therein over which the individual longitudinal side members may extend.
  • FIG. 1 there is illustrated a venetian blind assembly 1 constructed according to the invention as applied to a skylight opening formed by fixed end frame members 2 and 3 and fixed side frame members 4 and 5.
  • the blind assembly comprises a plurality of individual slats 6 each supported by two slat support means 7 and 8.
  • Slat support means 7 as shown in Figure 3 has two longitudinal side members 9 and 10 while slat support means 8 has two longitudinal side members 11 and 12.
  • the longitudinal side members have means thereon to support the slats, which in the drawings shown, comprise rungs 13 extending between spaced longitudinal side members of the same slat support means and between which a slat is inserted.
  • the slat support means illustrated thus comprises a conventional ladder tape where the tape cables form longitudinal side members. While a tape ladder is shown on a slat support means, it is to be understood that the longitudinal side members could be connected by clips or other means directly to each slat thus eliminating any need of rungs.
  • the venetian blind assembly as shown in Figure 1 also has a first headrail 15 containing a conventional slat tilt bar means (not shown) operated by a lever 16. An end of each slat support means 7 and 8 is connected to the tilt bar means. Headrail 15 is fixed by way of brackets 17 to the fixed end frame member 2.
  • a second headrail 18 is detachably connected by brackets 19 to the fixed end frame member 3 and, as shown in Figure 3, connects with the slat support means 7 and 8 by way of rollers 20, 20', 21 and 21' journalled to the headrail 18.
  • the longitudinal side members 9 and 10 of the slat support means 7 are operatively connected respectively to the longitudinal side members 11 and 12 of the slat support means 8 by resilient tension means in the form of tension springs 30 and 31.
  • the result is that all the longitudinal side members 9, 10, 11 and 12 will be under tension such that they may support the slats 6 regardless of the orientation of the blind assembly, that is not withstanding whether the assembly extends horizontally as occurs when used with a skylight, is inclined to a vertical plane or is in a vertical plane with the slats extending either vertically or horizontally.
  • longitudinal side member-resilient means connection arrangements by which the tension in all the longitudinal side members remains constant during tilting of the slats and regardless of the degree of tilting.
  • the longitudinal side members 9 and 10 of the slat support means 7 are joined together by a coupling 50 and extend over a pulley 51 while the longitudinal side members 11 and 12 of the slat support means 8 are joined together by a coupling 52 and extend over a pulley 53.
  • Pulleys 51 and 53 are operatively connected by a resilient means in the form of a tension spring 55 which will impart the same tension in all the members 9, 10, 11 and 12.
  • the members 9 and 10 are operatively joined together by a bracket 60 while members 11 and 12 are operatively joined together by a further bracket 61 where both brackets are semi-circular in shape.
  • a tension spring 62 connects the brackets 60 and 61 so that all the members 9-12 are under the same tension during all degrees of tilting of the slats to provide the force necessary to prevent the slats from sagging.
  • the side members are connected to each bracket at points 63 which are in alignment with point 64 where the spring 62 connects with the bracket which increases the stability of the arrangement, allows for better closure of the slats and reduces excess stress on the side members during extreme tilt positions when the side members of a single slat support means move towards each other.
  • the spring 62 has a clip at each end which extends through the point 64 so that arms 67 and 68 of the clip extend below and over a bracket to prevent its turning about the point 64 in a plane other than one containing the axes of the rollers 65, 65' and 66, 66'.
  • FIG. 7 also provides constant tension during all degrees of tilting.
  • a longitudinal side member on one side of the blind assembly and of one slat support means is operatively connected by a resilient means to a longitudinal side member of the other slat supporting means on the opposite side of the blind assembly.
  • member 10 of slat supporting means 7 is operatively connected by resilient means 71 to member 11 of slat supporting means 8 while member 9 is operatively connected by resilient means 70 to member 12.
  • the longitudinal side members on one side of the blind assembly will tend to be tensioned to a greater degree than the longitudinal side members on the opposite side of the blind assembly depending on the direction of tilt.
  • the decrease in tension of members 9 and 11 will be compensated by the increase of tension of members 10 and 12 with the result that the tension will remain constant.
  • the rollers 72, 72' and 73, 73' over which the side members extend are movable axially with respect to each other to accommodate movement of the side members towards and away from:ieach other during tilting of the slats.
  • slat support means 7 and 8 are shown connected to the end fixed frame member 3 by way of the headrail 18, they could be connected directly to the frame member by fastening the rollers 20 and 21 to the frame member.
  • the headrail 18 is preferably connected to the headrail 15 by a slat moving means 22 comprising cord 23 connected at one end to the headrail 18 by means not shown and connected at the other end to a ring 24 at the headrail 15.
  • a slat moving means 22 comprising cord 23 connected at one end to the headrail 18 by means not shown and connected at the other end to a ring 24 at the headrail 15.
  • Pulling ring 24, when the brackets 19 have been detached from the headrail 18, will move the headrail 18 and slats towards the headrail 15 thus making any cover of the opening formed by the fixed frame members, such as a skylight or glass pane, accessible for cleaning.
  • the headrail 18 may have a slide portion 25 on each end thereof as shown in Figures 2A and 2B slidable on a stop bead 26 forming part of the side fixed frame members in order to support the same when it is detached from the end frame member 3. Further each slat may also have a support portion 27 on each end thereof formed by a notch 28 cut in the slat where an edge 28' of the notch slides upon the stop bead 26. In order that the bead will not interfere with tilting of the slats, it is important that edge 28 extend along the tilt axis of the slat.
  • slide portion 25 of the headrail 18 and support portion 27 of the slats may provide some support for the slats and headrail 18, the main portion of the weight of the slats and headrail are carried by the slat support means when the headrail is connected to the fixed end frame member 3.
  • the primary purpose of the slide portion 25 and support portion 27 is to prevent sagging of the assembly when it is moved for purposes of cleaning a skylight or pane.
