Definitions

  • the present invention relates to a vertical blind headrail end cap assembly and a kit including such an end cap.
  • a vertical blind headrail can have a variety of different forms of end cap and drive mechanisms for rotating the operating shaft of the headrail.
  • the operating shafts themselves may take the form of a simple tilt rod in which case the travellers of the vertical blind are normally moved by pull cords.
  • the operating shaft is provided with a helical thread on it and this is used to translate the travellers to the desired position and thereafter to tilt them to the desired angle.
  • the drive mechanism for the operating shaft can also take many different forms.
  • it can be in the form of a pulley which is mounted on the shaft and is operated, for example, by a ball chain or a cord.
  • a pulley is illustrated mounted in a housing secured to a body portion of the end cap, the body portion being insertable into the end of the headrail.
  • it can be in the form of a wand tilter, that is one involving two bevel gears and an operating wand or rod.
  • 'DE-A-3 213 096 attempts to overcome this problem by providing a very complicated housing which has a portion which is made wide enough to accommodate the pulley and other portions which are designed to accommodate the gear wheels suitable for a wand tilter.
  • the present invention proposes that a plurality of different shaft drive means are provided, each having a separate housing, an operating shaft drive means rotatable in said housing, said drive means each including a hub, and a recess is formed in the body to accommodate the hub, means being associated with the outer face of the body portion for locating alternatively the housing of anyone of said plurality of shaft drive means.
  • the body portion may be provided with accommodation holes for at least two cord guide pins, said holes being spaced apart from one another and arranged with their centre axes parallel to the axis of the operating shaft.
  • the end cap assembly may further comprise, in the body portion, at least one accommodation space for a pull cord guide pulley, and at least one bearing space for rotatably accommodating a shaft for said pulley, said accommodation holes and said at least one bearing space being dimensioned to receive identical elements which can each form either a guide pin or a pulley shaft, as appropriate.
  • the shaft drive means may be in the form of a pulley and the housing may closely surround a part of the pulley circumference, the housing being provided with a number of cavities or projections and the housing located on, said cap body being formed with at least projection or cavity cooperating with one of said cavities or projections on the housing with respect to the end cap body portion.
  • the projection may be mounted on the end of a tongue on said body portion, enabling said projections to spring back and allow repositioning of the cover during or after installation of the assembly.
  • the operating shaft drive means may be in the form of a first gear and the housing rotatably accommodates a second gear for driving engagement with said first gear, the second gear being operable from the outside.
  • the housing may comprise a bearing for the end of the operating shaft and the second gear may form part of a wand operating construction.
  • the housing is fixed to the end cap by screws, and the locating means on the body portion of the end cap are screw holes.
  • the invention also contemplates a vertical blind headrail cap kit system comprising :
  • FIG. 1 there is illustrated a headrail 10 provided with conventional internal longitudinal ribs 12. Inserted into this headrail is an end cap 14 (Figure 1), and at the other end an end cap 15 ( Figure 2). These end caps are substantially identical but are mirror images of one another.
  • Each end cap is provided with a longitudinal bore 16 opening into a recess 18 in the body portion 20 of the end cap.
  • Formed at the outer end of each end cap is an end flange 22, which has a substantially flat outer face and is arranged to engage against the end of the headrail 10 to limit the movement of the end cap into the end of the headrail.
  • Accommodation spaces 24 are formed in the outer face of the end cap and extend right through the end cap and are separated from one another by a partition 26.
  • an upper bulge 28 Formed on the outer surface of the body portion 20 on one side is an upper bulge 28 and a lower bulge 30.
  • the upper bulge is closed at the end 32.
  • One or two pulleys 34 can be inserted into the accommodation spaces 24 and a bearing shaft 36 can pass through the pulley or pulleys and also through the gap 38 formed in the partition 26, with the ends being accommodated within the upper bulge 32 and a groove 33. Since the upper bulge 28 is closed at the end 32, this limits the inward movement of the pin 36 and hence of the pulley or pulleys 34.
  • Three guide pins 40 which are of identical construction to the bearing shaft 36, are inserted into accommodation holes 42 so that pull cords for the travellers of the vertical venetian blind can pass between the pins 40, and be separated from one another, before passing over the pulleys 34.
  • the end gap is also provided with screwholes 44, 46 the latter extending within the lower bulge 30.
  • a resilient tongue 48 having an outwardly extending projection 50 which can flex inwardly to a position in which its extremity is flush with the outer face of the flange.
  • the assembly is provided with a conventional operating drive shaft 52 which may either be a longitudinally grooved shaft, as shown, or can be a shaft provided with helical grooves which are used to move and operate the travellers.
  • the drive shaft 52 passes through the longitudinal bore 16 which is concentric with the recess 18.
  • a drive pulley 54 provided with the usual means to engage a ball chain and having a hub 56'which passes through a central opening 58 in a cover indicated by the general reference numeral 60, the hub being accommodated within the recess 18.
  • the cover is provided with an arcuate cover portion 62 to cover the bead chain carried on the pulley 54.
  • the pulley 54 and cover 60 are retained in place on the operating shaft 52 by a slip nut 64 and spring 66, thus urging the cover against the outer face of the flange 22.
  • the cover 60 is provided with a plurality of circumferentially spaced cavities 68, illustrated in the form of holes which pass right through the cover. These are positioned to engage selectively on the projection 50, thereby to position the cover portion 62 in one of several different rotational positions.
  • FIG. 3 illustrates another form of operating shaft 6 drive mechanism. Since the headrail and end caps are identical, like parts have been indicated by like reference numerals.
  • a wand operating gearbox indicated by the general reference numeral 70. This includes a housing 72 having countersunk holes 74 therein to accommodate screws 76 which can be threadedly engaged in the screwholes 44, 46 to hold the housing in place.
  • a longitudinally extending bearing sleeve 78 having a through bore 80 to act as a bearing.
  • the bore 80 is provided with a countersink at 82 to accommodate a slip nut 64 to hold the shaft 52 in position.
  • the gearbox includes a first bevel gear 84 having a hub 86 splined at 88 to engage in the grooves in the drive shaft 52.
  • the first bevel gear is in meshing engagement with a second bevel gear 86 having a hub 88 mounted for rotation in a bearing portion 90 formed in the housing, the hub having a ball connection 92 for connection to a wand operator. Rotation of the wand operator will cause rotation of the two bevel gears and thus of the operating drive shaft 52.
  • This construction also includes a slip nut 65 against a washer 94 and a spring 96 to hold the drive shaft 52 in place.
  • end cap of the present invention allows one to use, at will, either a pulley drive arrangement as shown in Figures 1 and 2 or a wand operated gearbox arrangement is illustrated in Figures 3 and 4.
  • the arrangement is such that either of these drives could be mounted at either end of the headrail using perfectly standard end caps.
