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.
  • the present invention provides an alternative mechanism useful in the provision of curtain or section doors irrespective of whether or not they are to be vertically moveable, horizontally moveable or otherwise.
  • the present invention consists in a door assembly of a kind having a door (preferably a sectioned type door but not necessa ⁇ ly so) tracking on either side of the door in a fixed track to allow reproducible opening and closing thereof, the assemblv being characterised in that 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
  • SUBSTTTUE SHEET 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 of being closed upon the door opener controlled rotation of such pinion in the other direction.
  • pinion a meshing door opening and/or closing gear, pinion or sprocket
  • rack may include a chain and the term “pinion” a sprocket.
  • 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
  • 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.
  • any such counterbalancing arrangement is preferably attached to the bottom section where the door is a sectioned door and preferably also there is provided one rack only on one edge and that rack is attached to said door at said lower section.
  • the door is a sectioned door and there is a channel track for wheels, rollers or the like of the sectioned door disposed on each side of the door (the rollers, wheels or the like extending outwardly from the edge of the door defined by the plurality of the panels) and preferably at least one of said tracks has [substantially corresponding to the locus of the tracking for the wheels, rollers or the like] a track (preferably a channel) for a flexible or deformable rack in accordance with the present invention.
  • 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 alwavs 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/closin * 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.
  • Preferably said method is performed using apparatus previously defined and/or using a rack providing element as hereinafter defined.
  • the present invention consists in a rack, said rack comprising a flexible elongate member capable of taking some loads in tension, and moulded teeth forms on said elongate member which define the teeth of the rack, said rack being deformable in at least one plane.
  • said at least one plane is one that allows the teeth to be configured on the outside of a convex curve.
  • said elongate member is in the form of a strap.
  • said strap includes profile or edging modifications or both (eg. perforations, kinks, ridges or the like) which assists in the association of the teeth forms thereto.
  • said teeth forms are formed from a plastics mate ⁇ al.
  • said teeth forms are moulded singly or as groups on said elongate member.
  • said elongate member is of a steel and there are preferably ridges or the like formed transversely thereof.
  • the moulding procedure is substantially as hereinafter described whether with or without reference to any of the particular drawings.
  • the invention consists in, in combination, as a kit for driving a tracked door, a rack, a door opener having a pinion adapted to mesh with said rack, and tracking for the rack to provide a locus of movement longitudinally of the rack whilst driven either way by the pinion, the rack throughout any such tracked movement being adapted for direct or indirect engagement to a said tracked door.
  • the present invention consists, in combination, a deformable rack in accordance with the present invention and a door opener having a pinion adapted to engage said rack.
  • a door opener having a pinion adapted to engage said rack.
  • said combination in addition includes a track for said rack.
  • said track for the rack is associated with a track to receive the wheels, rollers or the like of a sectioned door.

  • a mount, spider or housing 4 Splined, keyed or otherwise affixed to that input shaft 3 is a mount, spider or housing 4 which defines a plurality of axes 5 which lie on the circle 6 shown in Figure 5.
  • Each of these axes 5 is defined preferably by axles common for both the planetary gears 7 of the input side and the planetary gears 8 of the output side.
  • SUBSTITUE SHEET circle diameter B could be 52.20mm.
  • the pitch circle diameters C and D are respectively 16.23mm and 17.63mm in order to provide some semblance of self braking.
  • 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.
  • the arrangement as shown irrespective of the number of planetary gear sets (which are preferably identical on both the input and output sides) is such that as shown in Figure 5 the planetary gear pairs 7A and 8A can be moulded with the teeth in phase. Because of the disparity of one between the input and output internal gears preferably however there is a corresponding out of phase relationship between 7B and 8B and between 7C and 8C.
  • a non-flexible or non-deformable rack may be used, in the preferred form the rack can configure to a locus parallel to that of the rollers of the door or the equivalent.
  • a sectional door as might be used for a garage is tracked upwardly and back from the top of a door portal, the sections 1 1 of the door being supported by rollers at each edge.
  • These rollers 12 are guided within a channel 13 which preferably forms part of a structure 14.

  • the flexible rack is a member having teeth 17 (see Figure 9) incrementally moulded thereon singly or preferably in groups (preferably simultaneously as a core or other framing member is preferably configured by the moulding elements to ensure a good grip of the moulded elements thereon).
  • the flexible rack is provided with teeth 17 on at least that side to be driven as shown in Figure 7 preferably on a convex curve side of the exposed part of the flexible rack.
  • the rack is formed on high tensile strip steel 18 having periodic ridges, kinks or the like 19 (dimples and/or possible even perforations may suffice) onto which the moulded components are formed.
  • an upstand or key form 20 formed by the same moulding operation that forms the teeth to the right as shown in Figure 9 can be used in a subsequent presentation within the mould means to key or index upstand 20 internally of a tooth of the next mould sequence.
  • the kinks or ridges 19 are indexed to be within the mass of the teeth 17.
  • the flexible rack Preferably there is fixing of the flexible rack at one point only of the door.
  • a sectional door because of the variations in length of the door (as it concertinas slightly during its opening) it is not appropriate to fix the flexible rack at each end. It is better to attach at one point only (preferably the lower end although in other forms the upper end will suffice).
  • any form of mechanical connection of the door to the flexible rack is sufficient since the rack is capable of operating in both compression and in tension since it is confined guidably within its channel and is preferably structurally strong enough to cope with loadings.
  • both ends of the rack especially the end preferably attached to the door section, irrespective of the door condition [fully open, fully closed, and in between] are still within tracking (eg. a channel) for the rack.
  • the rack may be guidable on a rail preferably the track is a channel.
  • Figure 10 A shows the use of a linkage arm 21 pivotally attached at 22 and 23 respectively to the door section 1 1 and the rack 6.
  • Figure 10B shows a different form where a linking plate 24 fixed to the door section (or framing thereof) 1 1 includes an end to capture a projection 25 of the rack.
  • the known reproducible movement back and forth on or in its track by the rack allows the rack to be used as a means of setting limits for the operation of any appropriate door controller that might be used as the input means or as part of the input means.
  • the rack could be used to initiate directly mechanical switches or to initiate optical switching means depending on its positioning within its locus of movement and this could be moved to set the door operator in any appropriate known way so that it does not drive beyond the fully closed condition nor drive beyond the fully open condition.

Abstract

Cet entraînement est destiné à une porte roulant sur un rail, et il comprend un pignon d'entraînement (10) s'engrenant sur une crémaillère (16) qui déplace à son tour la porte, au fur et à mesure que cette crémaillère est déplacée dans le sens du rail sous l'action du pignon. On préfère utiliser une crémaillère souple (16), pouvant se déplacer sur un site présentant des courbes.
