Definitions

  • the present invention relates to improvements in and/or relating to a rack and pinion drive assembly.
  • the invention also consists in related means and methods.
  • doors are normally of three types - curtain, panel or sectioned.
  • a curtain door is normally pulled from a roll and normally consists of a pliable structure or an articulated structure usually provided with some measure of guidance on the edges thereof.
  • a panel door by contrast, is normally supported so as to be capable of being swung up and over an entrance way or otherwise hinged relative to an entrance way.
  • a sectioned door normally comprises a plurality of parallel hinged panels, each of which is substantially centrally pivoted along a pivot axis parallel to the hinge axes and the pivoting axle structures are preferably guided so that the section door can follow roughly to the locus of the guides.
  • PCT/NZ97/00143 W098/2143
  • the present invention provides an alternative means useful in the provision of curtain or section doors such as for example panelled or sectional doors irrespective of whether or not they are to be vertically moveable, horizontally moveable or otherwise. It is therefore an object of the present invention to provide means and/or methods which go some way to meet the aboyementioned desiderata or which will at least provide the public with an alternative drive assembly.
  • the present invention consists in a door assembly of a kind having a door (preferably a sectioned type door but not necessarily so) tracking on either side of the door in a fixed track to allow reproducible opening and closing thereof, wherein a rack is tracked to move on a fixed locus and is connected (directly or indirectly) to the door such that movement of such rack on its tracked locus will cause the opening or closing of the door, the rack being engaged by or being engageable by a meshing door opening and/or closing gear, pinion or sprocket (hereafter "pinion") of or from a door opener whereby the door is thus capable of being opened upon the door opener controlled rotation of said pinion in one direction, and wherein in transverse section (at least when projected longitudinally) said rack is bifurcated and the tracked locus is defined by a flange, rail, wall or the like
  • wall of the fixed track (preferably within which the tracking elements of the door move (eg; wheels, glides or the like, preferably wheels)), the rack being partly outside the wall and partly inside the wall, and wherein the pinion engages the rack over regions thereof on one side of (preferably outside of) the wall.
  • said tracking elements are wheels that capture part of the rack inside of the wall.
  • said pinion not only meshes with the rack outside of the wall but also keys or indexes into the rack (eg; by a wheel into a longitudinal accommodation of said rack).
  • said rack is of a form typified by the accompanying drawings.
  • said rack is moulded about a tensile strength strengthening member and the axis thereof is to be outside of said wall.
  • said rack is sufficiently flexible or deformable so as axially to follow a curved track whilst being driven/pulled/pushed by said pinion.
  • said deformable rack follows a locus appropriate for a sectioned door (preferably a similar locus to that of the tracks of the door).
  • said door is a sectioned type door.
  • said locus includes a curve and preferably said pinion providing the drive is at said curve.
  • said pinion is on the convex side of a curve.
  • said rack can be driven in compression to take the door with it or can be moved in tension to take the door with it.
  • a lower region only of the door is fixed to said rack.
  • said rack is of a form hereinafter defined and/or described.
  • said door is counterbalanced by a pulley and weight system or use of a torsion or spring arrangement linked to the door.

  • a non-flexible or deformable rack can be utilised if there is sufficient head room for the rack to continue upwardly over the door portal, such a form of the invention is much less preferred than one that does not require such head room, ie. utilises a flexible and/or deformable rack which can always be accommodated since it can be associated with the locus of the track required for the door in any event.
  • the present invention consists in a method of opening/closing a curtain, panel or sectioned door (preferably sectioned) which comprises engaging the door at an edge with a rack capable of being driven by a pinion in at least one of two directions (preferably both directions), and subsequently using the pinion to open or close the door and wherein said method involves the operative use of a door assembly, combination, or rack of the present invention.

  • the sets of planetary gears 7 and 8 (preferably of identical form) rotate on a common set of axles within the same mount or on the same mount 4.

  • the self braking however, notwithstanding the disparate tooth numbers on pitch circles A and B (preferably a disparity of one), is not as good as where the pitch circle diameters are identical (eg. as in the case of Figure 5).
  • self braking means no more than the ability to resist the transmission of movement back through the gear assembly from the output side.
  • the preferred form of that invention however has a direct input shaft without an sun gear and simply drives a plurality of spaced planetary axle members which on the input side have idle gears driven by the fixed "input" side internal gear so that the thus driven idle input gears directly drive the planetary gears of the output side thereby imparting a rotational drive (and a drive of significantly increased torque) onto the internal gear of the output side.
