Definitions

  • a principal object is the provision of a head assembly combining unitary tilt control and blind actuating mechanism that may be manually or power operated. Further aspects of the, invention are concerned with means for attaching the ladder tapes to the head control support, attachment of the ladder tapes and/ or blind cords to a bottom rail, design of the ladder tape and slats to render the latter readily removable for cleaning purposes and means for pivotally hanging the head assembly.
  • a head assembly comprising tilt control and blind raising and lowering mechanism basically includes a tape drum, a cord spool and a mounting spindle therefor all embodied in a single unit adapted for association with a section of head tube and for rotatable mounting in a support bracket.
  • the mentioned single unit may comprise a cylindrical spindle formed with a flat extending [from end to end thereof, an externally threaded cord spool being slidably mounted on said spindle and a tape drum being rotatably supported by and concentric with said cord spool in screw threaded engagement with the latter.
  • the said tape drum is centrally disposed between a pair of end caps, one of which is non-rotatably secured to each end of said spindle as by means of an attachment screw,
  • each cap being formed with an interior socket which is complementary in cross-section to that of said spindle.
  • a ladder tape are secured, as by means of a spring wire clip, to said tape drum at 'angularly spaced points on opposite sides of a vertical plane coinciding with the axis of said drum and the threads, provided inside said drum for engagement with the exterior threads on said cord spool, extend from one end of said drum to a medial point thereon which coincides with a circumferential slit therein for the passage of a blind lifting and lowering cord which is attached to the corresponding end of the cord spool and is adapted to be wound in the threads of said spool, as same emerge from the threaded portion of the tape drum, during rota- "ice tion of said spool in one direction to raise the blind.
  • a semi-cylindrical cover for the tape drum may be provided for clipped engagement with the rebated inner end of one of said end caps and the similarly rebated inner end of the companion end cap is adapted to be received by a hangar bracket to be described later.
  • One of the single unit assemblies described above would be associated with each lift cord station of a blind and adjacent unit assemblies, in a series thereof, may conveniently be coupled together by means of a lock-seam type of tube having a smooth outer surface and the lock seam disposed interiorly thereof to constitute a key or spline for engaging complementary longitudinally extending grooves formed on the cylindrical outer face of the end caps of said units.
  • the latter may conveniently be moulded from plastics material which may also be used for the other elements of said units vizthe spindle, the cord spool, the tape drum and the cover for the latter.
  • the means for securing the upper tape ends to said tape drum may comprise a clip formed from spring wire, said clip being of generally circular formation to engage in an annular rebate formed on one end of the tape drum, a pair of angularly spaced grooves extending from said rebate longitudinally of the tape drum to accommodate offset ends of said clip, and around which the return bent or folded over ends of the ladder tapes of the blind are engaged.
  • the circular portion of the wire clip may be formed with waves or sinuosities to provide a frictional braking effect between the vertical face of the drum-end rebate and the inner end face of an associated end cap.
  • initial rotation of a series of unit assemblies coupled together as above will impart tilt to the blind slats while further rotation thereof will effect raising or lowering of the blind according to the direction of rotation.
  • the aforesaid rotation may be effected by press button control of a reversible electric motor suitably geared to one of said unit assemblies or such rotation may be effected manually as by an endless cord passing over a sheave having a tapered cord receiving groove and, conveniently, one of said sheaves may be coupled to an end unit assembly by means of a short section of lock-seam tube as referred to above.
  • a torsion spring such as a clock-spring or the like may be attached at one of its ends to the sheave and at its other end to one of the mounting brackets.
  • the normally outer end of the sheave boss may be reduced in diameter to correspond to that of the rebated ends of the end caps of said units whereby a standardised mounting bracket may rotatably receive the said reduced diameter sheave boss or said end cap.
  • a mounting bracket may comprise a plastics moulding of T- or L-section and having a centrally disposed hookshaped web merging the inner faces of the flanges of the T or L, the opening of the hook-web having a flared mouth to permit forced entry therein of one of the above mentioned sheave bosses or the rebated end of one of said unit end caps.
  • Both of the L-related flanges of the bracket may be apertured to receive attachment screws for top or back mounting of the bracket and the under face of the upper flange of the bracket may be formed with undercut ribs or grooves to receive the mounting member of a pelrnet or fascia strip. .Alternatively, such grooves may be formed on opposite faces of said hook-web.
  • rock et plate is also laterally offset in the opposite'senseat -a higher level to provide a stop adapted to abut the free endof the bracket hook thereby to maintain the lower end of the rocker plate, in ajforward position so that the dangling endless cord will hang forwardly'of, the array of blind slats.
  • the said W-spring may also embody means, for example, a flat section tapes and/tor thelift cords in a bottom bar and, to that key or cam is inserted between the inner limbsof the W Y and rotated, the outer limbs of the W .will emerge through tape ends are then disposed between the said outer limbs of the W.-spring andthe bottom bar side walls, said limbs will hook said ends through the associated slots when the key orcam is rotated further to permit restoration of the limbs of the W-spring to their normallyfcont'racted condition.
  • the said W-spring may also embody means, for example, a flat section tapes and/tor thelift cords in a bottom bar and, to that key or cam is inserted between the inner limbsof the W Y and rotated, the outer limbs of the W .will emerge through tape ends are then disposed between the said outer limbs of the W.-spring andthe bottom bar side walls, said limbs will hook said ends through the associated slots when

  • a head assembly for a Venetian blind andincluding a unitaryslat tilt and raising-and-lowering mechanism includes a' tape drum 20, a cord spool'21 and a cylindrical mounting spindle 22 therefor, said spindle being formed With a longitudinal" flat 23 extending from end-to-end thereof.
  • Cord spool 21 is formed interiorly, with an axial bore 24.of corresponding cross section to that of spindle 22 so that the former mayslide on the latter without relative rotation. Exteriorly, cord spool 21 is formed with screw threads 25 for engagement with. corresponding threads 26 formed within one half of tape drum 2 0, preferred configurations for both of said threads being depicted by FIG. 7. i
  • the tape drum 20 is centrally: disposed between a pair of end caps 26 and 27, one of which is non- ,ture is formed in said box-section bottombar by cut-ting away a portion'of' the upper surface and a'p'ortion 10f a rotatably mounted on each end of'spindle 22 by means of an interior socket" 28 having a corresponding cross sectional shape tothat of spindle 22.
  • tape drum 20 extends from one endvthereof to a medial position thereon and which is defined by a circumferential slit 34' for passing a slat-lift 'cord 35 to and -fromsaid cord spool 21'.
  • Cord 35 is attached to that rest upon the upper surface of said bar,,thus causing the end of a tape, which has previously been inserted within said ,apertureto the required depth, to be; gripped against said anchoringm'ember and thusfheld relatively to said bar.
  • This'flatter arrangement. may also embody means for anchoring the lower end-of a lift cord passed through a hole or slot. inithe upper surface ofsaid bottom bar,
  • the cord may be prQVidedwith a firmly attached coaxial ferrule or the like which'is just too large; to pass through any said slot.

  • a substantially semi-cylindrical cover 36 extending for an angular distance slightly exceeding 180, may be clipped onto the rebated end of adjacent end cap 27 to cover the upper portion of tape drum and exclude dust and fluff therefrom.
  • One of the unitary assemblies, as described above, should be associated with each lift-cord station of a Venetian blind and, further according to the invention, adjacent units are coupled together by means of a length of lock-seam tube 37 having a smooth outer surface and the lock-seam disposed interiorly thereof, thereby to provide a key or spline 38 for engaging a complementary groove 39 formed in each of the end caps 26 and 27.
  • initial rotation of a, or each, cord spool will tilt the blind slats to closed position (if they are not already in that position) and continued rotation of the spool or spools will effect raising or lowering of said slats, according to the direction of said rotation.
  • rotation of the cord spool or spools may be effected by means of a reversible electric motor coupled to the outermost end cap 26 or 27 of a series of said unitary assemblies or such rotation may be achieved manually by means of an endless cord 40 passing over a sheave 41 having a tapered cord groove 42 and, also according to the invention, a unit rotating sheave may conveniently be coupled to one of said unitary assemblies by a further lock-seam tube 37 of which the lock-seam 38, at one end thereof, engages in a groove 39 in end cap 26 while the opposite end of said lock-seam engages in a similar groove 39 in tubular boss 43 of sheave 41. From the drawings, it will be evident that end caps 26 and 27 and also the boss 43 of sheave 41 are adapted snugly to fit within associated ends of tubes 37.
  • a standardised mounting bracket 46 may constitute end and intermediate bearings for rotatably mounting a complete series of unitary assemblies and also a drive sheave therefor.
