Definitions

  • the invention relates to an apparatus for operating blinds, and in particular, the invention relates to an apparatus for operating vertical blinds around a corner.
  • Vertical blinds generally comprise a plurality of evenly spaced vertical slats, downwardly depending from travellers held in a horizontal track.
  • the track is affixed to the ceiling or upper casement of a window.
  • Each slat is rotatably attached to a single traveller which is slidable within the track.
  • a horizontal shaft connects all the travellers. Rotation of the shaft, through a suitable means in each traveller (such as a worm gear) causes the slats to rotate.
  • Each traveller is connected to adjacent travellers by suitable movable connection means whereby, in one direction each traveller can be moved to contact another traveller, and, in an opposite direction the travellers move apart from each other.
  • Suitable control means such as cords, chains, or shafts
  • the travellers can be moved longitudinally along the track, and whereby the shaft can be turned to rotate the vertical slats.
  • such controls are located at one end of the track.
  • the travellers in all groups should be capable of being moved between fully open and fully closed positions simultaneously, by a single control.
  • a known type of this blind apparatus for use with bay windows is disclosed in GB-A-1,470,533, which apparatus comprises: a curved track; a flexible bent rotation shaft extending longitudinally of the track; means attached to, and arranged to control rotation of, the rotation shaft; a plurality of travellers which are received slidably in the track, from which vertical slats hang, of which each has a rotatable slat shaft and is connected to the rotation shaft and at least one lead traveller is constrained to move along a path of predetermined length within the track from an open position, at one end off the path, to a closed position at the other end of the path; and traverse drive means engageable with said at least one lead traveller and operable to move said traveller between said open and closed positions and, as a consequence, the remaining travellers and the slats between respective open and closed positions.
  • blind apparatus could be oriented in any position including vertically, horizontally or in any other position.
  • the inventive blind apparatus is characterised in that at least two tracks have adjacent ends, which meet at a corner defined therebetween and have respective rotation shafts and in that flexible coupling means connects adjacent rotation shafts at the associated corner, said at least two tracks being of first and second predetermined lengths, whereby the lead traveller in the shorter track is constrained to move along a lead traveller path shorter than that of the other, longer track, movable coupling means coupling said traverse drive means to the lead traveller in the shorter track, whereby, when the shorter track lead traveller reaches the limit of its path, said movable coupling means permits said traverse drive means to continue to move the lead traveller in the longer track.
  • Bay window 10 comprises, in this illustration, left side 12, front side 14, and right side 16.
  • Left side 12 is joined to front side 14 at corner 18.
  • front side 14 and right side 16 are joined at another corner 20.
  • the sides 12, 14 and 16 may each define different lengths.
  • corners 18 and 20 may define different angles.
  • the left side 12 of window 10 includes an upper casement 22.
  • sides 14 and 16 include upper casements 24 and 26 respectively.
  • a vertical blind apparatus, according to the invention, indicated generally as 28, is affixed to and depends downwardly from upper casements 22, 24 and 26.
  • the invention is equally applicable to two sides, or four, or more.
  • Vertical blind apparatus 28 comprises horizontal tracks 30, 32 and 34 afixed respectively to upper casements 22, 24 and 26 and mitered together at corners 18 and 20. Slidably held within tracks 30, 32 and 34 are a plurality of travellers 36 (see Figure 2). Rotatably attached to each traveller 36 is a downwardly depending slat 38. Slat 38 generally comprises an opaque material, so that when the vertical blind apparatus 28 is in a closed position light is prevented from entering bay window 10.
  • Travellers 36 slidably support slats 38. Furthermore, travellers 36 are interconnected by suitable movable link means 82, as discussed below, for longitudinally moving the travellers 36.
  • free ends 54a and 56a of longitudinal control cords 54 and 56 depend from a free end of track 34, at one end of the blind.
  • a suitable pulley (not shown) may be provided at such end to allow for smooth movement of cords 54 and 56.
  • Cords 54 and 56 are connected, as disclosed herein, to a lead traveller (as, for example, lead traveller 36a or 36b in Figure 3) in each track 30, 32 and 34.
  • a lead traveller as, for example, lead traveller 36a or 36b in Figure 3
  • cords 54 and 56 are joined together and, in fact, may be integral with each other.
  • a suitable pulley (not shown) may be provided at such opposite end to allow for smooth movement of cords 54 and 56.
  • the free ends 54a and 56a of cords 54 and 56, respectively, may be tied or otherwise connected together and, in fact, may be integral with each other.
  • Cords 54 and 56 may be pulled to move travellers 36 longitudinally within tracks 30, 32 and 34. Such longitudinal movement causes slats 38 to be drawn sideways between open and closed positions, as well as through intermediate positions therebetween.
  • Rotation transmission means typically worm gears (not shown), are incorporated in each traveller 36, and connected between the rotation shaft 40 and respective slats 38. Rotation of such worm gear rotates the slats 38.
  • Lead travellers 36a and 36b are movable along lead traveller paths 35 and 33, respectively (indicated in phantom in Figure 3).
  • Paths 35 and 33 have predetermined path lengths. In the illustrated embodiment, such path lengths correspond generally to the length of the tracks 32 and 34 (with an allowance for the length of the collapsed travellers 36 in the open position). However, the path lengths could be restricted to any fraction of the lengths of the tracks 32 and 34. Such restriction may be necessary, for example, in the situation where more than one lead traveller is provided in the same track (as in the case of a centre pull opening or multiple opening vertical blind apparatus).
  • the length of the path will depend upon the number of travellers in the track.
  • the number of travellers will in turn depend on the width of the window (or space) to be covered by the slats.
  • the invention permits the movement of travellers arranged in groups of travellers of unequal numbers, in a manner to be described below.
  • Tracks 32 and 34 meeting at a corner, indicated generally as 20.
  • Tracks 32 and 34 are affixed by any suitable means to upper casements 24 and 26, respectively (see Figure 1).
  • Travellers 36 are slidably held within tracks 32 and 34.
  • Each traveller 36 includes a rotatable slat shaft 37.
  • a slat 38 is affixed to each slat shaft 37.
  • a rotation shaft 40 extends along the length of each track 32 and 34 from one end to the other.
  • Shaft 40 is rotatably supported by a suitable support means, such as bearing blocks 42 affixed at each end of tracks 32 and 34.
  • Bearing block 42 defines a suitable hole allowing shaft 40 to extend therethrough.
  • each traveller 36 defines a suitable opening allowing shaft 40 to pass therethrough.
  • a suitable gear or other transmission means known in the art (not shown) is included in each traveller 36 and is adapted to cooperate with shaft 40, whereby rotation of shaft 40 will induce each slat shaft 37 to rotate. Rotation of slat shafts 37 in unison will cause slats 38 to either open or close, as desired.
  • a suitable pulley 43, or other means may be attached at one end of shaft 40 and may be operable by a suitable cord, chain or other means (see cord 41 in Figure 1).
  • Adjacent shafts 40 are connected together at corner 20 by flexible coupling means 44.
  • the bearing blocks 42 are arranged at either end of the flexible coupling means 44 to locate the ends of the shafts 40 adjacent the flexible coupling means 44.
  • flexible coupling means 44 comprises a cylindrical helical spring 46 affixed to collars 48 at each end. Collars 48 in turn are affixed by suitable means, such as set screw 50, to each shaft 40. For protection and for ease of rotation, washers 52 may be inserted in place between collars 48 and bearing blocks 42.
  • Each collar 48 defines a boss 48a extending therefrom in order to assist in affixing spring 46to collars 48.
  • the spring 46 may be wrapped around and affixed to the bosses 48a by suitable means.
  • a spring for example, a spring, a universal joint, or a series of universal joints, a flexible hose (such as a rubber hose) or a flexible cable (such as is used in a speedometer cable) may be used.
  • a flexible hose such as a rubber hose
  • a flexible cable such as is used in a speedometer cable
  • cords 54 and 56 are used to move travellers 36 longitudinally within tracks 32 and 34 in order to open and close the vertical blind apparatus 28.
  • a dual pulley arrangement 58 is affixed between tracks 34 and 32 at corner 20.
  • Dual pulley 58 includes two pulley wheels 58a, rotatable in opposite directions.
  • Cord 54 lies within the groove of one such pulley wheel 58a and cord 56 lies within the groove of the other pulley wheel 58a.
  • a dual pulley 58 it may be necessary to use a dual pulley 58.
  • a smooth rounded plate, effectively rounding off corner 20 or a bent hollow tube may be found suitable.
  • cords 54 and 56 may cause cords 54 and 56 to bind together, thereby interfering with the smooth functioning of the vertical blind apparatus. It has been found that the dual pulley arrangement is preferable.
  • FIG. 3 a schematic plan view of tracks 32 and 34 meeting at corner 20 is provided.
  • the outline of tracks 32 and 34 is shown in phantom.
  • Groups of travellers 36 are constrained to move within tracks 32 and 34.
  • track 34 has a group of five travellers, and track 32 has a group of four travellers.
  • lead traveller path 35 in track 34 is somewhat longer than lead traveller path 33 in track 32.
  • cords 54 and 56 are provided with movable connectors for connection to the lead travellers.
  • Cords 54 and 56 are integral with each other, or tied together, at one end. At the other end the free ends 54a and 56a of cords 54 and 56 depend downwardly. A human operator may open and close the blinds by pulling on the free ends 54a and 56a of cords 54 and 56.
  • Cord 56 is connected to the lead traveller 36a in track 34, having the longest path, in this case path 35.
  • Cord 54 is connected, as described below, to the lead traveller 36b in path 33, the shorter path.
  • lead traveller 36a is illustrated.
  • One means of attaching cord 56 to traveller 36a is to attach traveller engagement means 64 to cord 56 between two panels 66 and 68 of traveller 36a. Panels 66 and 68 define suitable openings allowing cord 56 to pass therethrough. When cord 56 is pulled in one direction or the other, engagement means 64 will engage and abut against either panel 66 or panel 68, thereby causing lead traveller 36a to move.
  • Engagement means 64 may comprise a spherical ball which is crimped about cord 56.
  • Other means of attaching cord 56 to traveller 36a may be used. For example, cord 56 may simply be tied or wrapped around a portion of traveller 36a.
  • Traveller 36b may include panels 70 and 72, each panel 70 and 72 defining an opening 74 therein.
  • Cord 54 passes through openings 74.
  • a washer 76 may be loosely arranged around cord 54.
  • the outer diameter of washer 76 is sufficiently large that washer 76 cannot pass through openings 74.

  • the diameters of engagement means 78 and 80 are sufficiently small to pass through openings 74 in panels 72 and 70, but are also sufficiently large that they may not pass through a central aperture 77 of washer 76.
  • Cords 54 and 56 are only attached or attachable to the lead travellers 36a and 36b. Cords 54 and 56 pass around or through the other travellers 36 (at suitable openings provided therein) and are not attached or attachable thereto.
  • Lead travellers 36a and 36b are each connected to an adjacent traveller 36 (which in turn is connected to a train of subsequent slider blocks 36) by suitable link means 82.
  • Link means 82 are movable relative to the travellers whereby when lead traveller 36a or 36b is moved a predetermined distance in the closing direction, such traveller 36a or 36b will commence pulling the subsequent traveller 36.
  • the link means 82 is movable to allow the lead traveller 36a or 36b to approach and abut against an adjacent traveller 36. Thereafter further movement of lead traveller 36a or 36b will also cause travellers 36 to close up as well. Subsequent travellers 36 are either opened or closed in corresponding fashion by interconnecting link means 82 linking adjacent travellers 36.

  • Dual pulley arrangement 58 allows cords 54 and 56 to move in opposite directions relative to each other around corner 20 without binding.
  • Cord 54 moves loosely through aperture 74 in lead traveller 36b, and at first the lead traveller 36b remains in the fully open position.
  • both lead travellers 36a and 36b move toward the closed position. Both travellers 36a and 36b pull, by link means 82, a group or train of travellers 36 therebehind.
