Definitions

  • the present invention relates to doors and in particular to slatted doors suitable for use in an industrial application. Doors of this kind are sometimes known as 'high speed doors'.
  • the door of the present application is suitable for an opening such as an entrance to a garage, warehouse or the like.
  • the door includes a plurality of slats or panels which are moveable between a closed position and an open position of the door. In the closed position of the door, the slats or panels abut side by side to substantially cover the opening. In the open position of the door, the slats or panels are repositioned in a face to face relationship to substantially uncover the opening.
  • Doors of the above kind are broadly known, inter alia, from AU Patent Specification 235268 to K-M Steel Products Pty. Ltd.
  • a disadvantage of the door disclosed in this reference is that it is not suitable in an environment in which the door is subjected to relatively high wind pressure such as may be experienced in a hurricane or cyclone. Slatted doors are inherently unstable under such conditions.
  • a curtain comprising a plurality of slats, is wound up by means of a drum under high pressure. This can cause damage to exposed surfaces when the curtain is operated.
  • shutters of this kind require wind locks on the end of the curtain. However, the wind locks come into effect even under conditions of minor wind.
  • An object of the present invention is to alleviate the disadvantages of the prior art or to at least provide the public with a choice.
  • a door for an opening said door including a plurality of slats moveable between a closed position in which the slats abut side by side to substantially cover the opening and an open position in which the slats are arranged face to face to substantially uncover the opening, said door including: means for guiding said slats between said open and closed positions; and means associated with said guiding means for biasing said slats towards said closed position.
  • the guiding means may include a plurality of pantographs.
  • the pantographs may be arranged to pivot between a first position associated with the open position of the door, and a second position associated with the closed position of the door, when the biasing means is fully biasing the slats.
  • the guiding means may include means for attaching the pantographs to at least one slat so that when the pantographs pivot between the first and second positions, the slat moves between its open and closed positions.
  • the attaching means includes the biasing means.
  • the biasing means may include a torsion bar.
  • the biasing means may be actuated when the slats first abut each other.
  • the biasing means may fully bias the slats when the pantographs are in the second position.
  • one end of the torsion bar may be attached to a pivot axis associated with the pantographs and the other end of the torsion bar may be attached to a slat.
  • the other end of the torsion bar preferably is attached to the slat at a position that is spaced inwardly from one end of the slat. The position of attachment may be spaced inwardly approximately 25% of the length of the slat.
  • the door may include means for counterbalancing moving parts including the slats, of the door.
  • the door may include means for driving the guiding means between the open and closed positions.
  • the driving means may be an electric, pneumatic or hydraulic motor- gear unit.
  • FIG. 1 is a sectional front view along I-I in FIG. 2 showing an example of a slatted door according to the invention in a closed position in which parts of the covers and a guide element on the left-hand side thereof are removed;
  • FIG. 2 shows a sectional view along II-II in FIG. 1 ;
  • FIG. 3 shows a sectional view along III-III in FIG. 1 ;
  • FIG. 4 shows a sectional view along IV-IV in FIG. 1
  • FIG. 5 is an enlarged sectional front view of the headroom area of the left- hand frame taken along V-V in FIG. 6;
  • FIG. 6 shows a sectional view along VI-VI in FIG. 5 in which front covers and end seals are omitted for reasons of clarity;
  • FIG. 7 is a sectional side view along VII-VII in FIG. 8 showing the headroom area in an open-door position in which end seals are not shown for reasons of clarity;
  • FIG. 8 is a sectional top view along Vffl-Vffl in FIG. 7 when door is open, and shows the left-hand frame with covers installed;
  • FIG. 9 is a partially cut away, right side view of FIG. 10 in a closed-door position, and without panels for reasons of clarity;
  • FIG. 10 is a sectional left side view along X-X in FIG. 9;
  • FIG. 11 is a partially cut away view of the head- room area and shows end seals and panels in an open door position
  • FIG. 12 shows an alternative assembly to FIG. 8;
  • FIG. 13 shows one form of means for connecting the transmission elements to panels;
  • FIG. 14 shows a sectional view along XIV-XIV in FIG. 15, of the preferred connection between transmission elements and panels;
  • FIG. 15 shows a partially view of FIG. 14;
  • FIG. 16 shows the principle of an alternative counterbalance assembly;
  • FIG. 17 is an alternative embodiment to FIG. 7 and shows reinforced panels in an open door position;
  • FIG. 18 shows the reinforced panels of FIG. 17 in a closed-door position;
  • FIG. 19 shows another embodiment of reinforced panels in a closed-door position
  • FIG. 20 shows the panels of FIG. 19 in an open-door position.
  • the slatted door assembly 1 basically comprises a plurality of movable slats or panels 2, a synchronising and guiding mechanism 3 at each end of the panels 2, a counterbalance assembly 4 preferably acting on each synchronising and guiding mechanism 3, a pair of symmetrical self supporting frame assemblies 5, and a drive assembly 6.
  • FIGS. 5-6 show one form of synchronising and guiding mechanism 3 in conjunction with the panels 2.
  • the synchronising and guiding mechanism 3 includes a plurality of pantographs 8 wherein one center shaft 9 located at the end of the pantograph assembly 8 pivots in a self-aligning bearing 10.
  • the synchronizing and guiding mechanism 3 further includes center shafts 13-14, torsion members 11 , at least one rotatable rope guide 35, and a support roller 21 installed on each, or preferably each second, center shaft of pantographs 8. In another embodiment support rollers 21 may be replaced with sliding pads.
  • FIG 12 To determine the direction of rotation of the support rollers, another embodiment of the invention, shown in FIG 12, comprises a support roller 22 and a support roller 23, installed on each center shaft 14 of pantographs 8.
  • center shaft 9 is fixed to a torsion member 11.
  • Each torsion member 11 includes an elongate element.
  • the elongate element may be solid or hollow such as tubular. It is possible to replace the combination of the torsion member 11 and center shaft by a single element.
  • Each torsion member 11 is connected to a pivot axis associated with one lever 12 of pantograph 8. This connection can be form-fitting or can be achieved by welding, for example. To facilitate installation at the building site, all parts of the synchronising and guiding mechanism 3 may be pre-assembled. It may be seen in FIG. 4 and FIGS. 5-6 that intermediate panels 7, top panel 15 and bottom panel 16 inclusive, have inserted therein torsion members
  • the torsion member 11 which transmits a desired rotation to all panels.
  • the torsion member 11 also transmits synchronised movement in a vertical direction, to all panels except top panel 15 which rotates only.
  • FIG. 13 is shown in FIG. 13 and in FIGS. 14-15.
  • FIG. 13 shows torsion member 11 connected to a panel 7 by means of a spring pin 70.
  • FIGS. 14-15 The preferred version shown in FIGS. 14-15 includes a driving lug 18 fitted to each end of a torsion member 11 for transmitting torque to a driving slot 19 associated with a panel.
  • the driving lug 18 is placed a distance Dl (refer Fig. 15) in from the end
  • the distance Dl is related to the length of the torsion member and is determined by reference to the elasticity of the torsion member, the bias or preload tension to be applied to the panels and the angular displacement required of the torsion member. These calculations are well within the capability of the skilled addressee and are therefore not provided herein.
  • the point of attachment of the torsion member and/or the length of the torsion member may be chosen so that flexing of the panels is minimized. Where a pair of torsion members is applied to each panel, they may be attached at points spaced inwardly approximately 25% from the ends of a panel.
  • This may provide a substantially uniform distribution of preload tension to each panel in a closed- door position.
  • the flexible nature of the torsion members 11 may also perform a safety role, because, in the event that a human hand or other body part is accidentally caught between two adjacent panels preventing them from closing completely, the driving force may be taken up by an increase in preload tension and may not cause permanent injury. Also, if the door is accidentally closed at too high a speed, damage to the door may be avoided because the torsion members 11 can twist and absorb energy.
  • top panel 15 and bottom panel 16 there is installed between top panel 15 and bottom panel 16 a number of similar intermediate panels 7.
  • panel 15 and intermediate panels 7 are fitted with seals 24.
  • Panel 15 is packed by seal 67 which is fitted to top-plate 40.
  • a channel 25 is inserted in bottom panel 16.
  • Channel 25 receives a lower seal 26 equipped with integrated safety components.
  • Lower seal 26 is commonly called a safety edge and is available in different forms as a standard product for high speed doors.
  • Top panel 15 and bottom panel 16 may be formed without special tools, by re-machining intermediate panels 7.
  • the panels may be made from extruded aluminium or from preformed steel. To reduce inertia of the panels, they may be formed from composite materials and may contain reinforcing fibers such as carbon or glass.
  • each end seal 27 preferably comprises a layer 29 with good sliding properties such as Teflon, a compressible and elastic core 30, which can be made of Polystyrene foam or an equivalent material, and an outer layer with lugs 31 for insertion into the panels.
  • end seal 27 may be formed from a single hollow and soft PVC material laminated with a low-friction coating.
  • FIGS. 17-18 For extra wide door-openings and extreme wind pressure, a reinforced version is shown in FIGS. 17-18.
  • each panel 32 is reinforced with an extended rib section 33. This arrangement increases rigidity of the panels without the need for additional headroom.
  • a gap 28 is also provided around the whole section of panel 32.
  • Rope 36 supports center shaft 14 by means of rope- guide 35.
  • Rope guide 35 is preferably located as close as possible to the center shaft 14 of bottom panel 16 or to center-shaft 14 of bottom-panel 16 itself.
  • Two spaced pulleys 37 guide rope 36.
  • the ends of rope 36 are connected to counterweight 38.
  • synchronizing or timing belt 39 may be replaced by an equivalent means such as a chain.
  • dynamic drive forces Fd can be transmitted to the center of mass of counterweight 38 by a pneumatic or hydraulic cylinder.
  • rope 36 may be used not only to transmit a counterbalance force Fc but also to transmit positive and negative dynamic drive forces Fd to center shaft 14.
  • rope 36 may be arranged to support a second center shaft 14 to reduce stress in the components of the synchronising and guiding mechanism 3.
  • the kinetic energy of counterweight 38 may be reduced to 50% as shown in FIG. 16.
  • the mass of the counterweight 38 can be doubled, to reduce its speed by 50%. As will be clear to those skilled in the art this arrangement may reduce the kinetic energy of the moving mass by a factor of two.
  • counterweight 38 may be replaced with a spring balance system, to provide a constant counterbalance force Fc.
  • a constant counterbalance force can be provided by means of constant force springs made from flat spring steel, or as known in various door applications, by a combination of a torsion spring and a tapered drum.
  • each self-supporting frame assembly 5 includes a top plate 40 and a bottom plate 41 , connected to vertical members 42 and 43.
  • Frame assembly 5 includes mountings 48, 49 and 50 for pulleys.
  • Frame assembly 5 also includes self-aligning bearing 10 connected as shown to top plate 40, and mountings 49 connected to bottom plate 41.
  • the vertical members 42 and 43 are designed to take all dynamic and static forces, due to counterweight 38, the weight of the panels 2 and the weight of the synchronising and guiding mechanism 3.
  • the frame assembly 5 includes removable covers 44 and 45 for easy access, a removable and adjustable guide- cover 46 and a removable guide 47.
  • vertical members 51 and 52 of the self-supporting frame assembly 5 can withstand all forces.
  • vertical member 55, guide member 53 and guide member 54 made of two hollow sections as shown, or as a single part, can be removed, following removal of covers 56, 57 and 58.
  • support roller 22 applies a force to the runway of guide member 53 only, because gap 60 prevents contact with the runway of guide member 54. Also, because of gap 59, support roller 23 applies a force to the runway of guide member 54 only.
  • the preferred embodiment of drive assembly 6 includes in each self-supporting frame 5, a synchronizing or timing (idling) pulley 61 for synchronizing or timing belt 39 journalled for rotation on mountings 49, and a timing pulley 62 for timing belts 39 and 63, journalled for rotation on mountings 49.
  • Drive assembly 6 further includes a motor-gear unit 65, which can be installed to the left or right of self-supporting frame 5, and synchronizing pulleys 68 fixed to shaft 64.
  • Shaft 64 is rotatably mounted in at least two self-aligning bearings 66.
  • the preferred version of the motor-gear unit is electric and with power being supplied by a soft-starter such as a frequency converter.
  • the apparatus may be powered by a pneumatic or hydraulic motor-gear unit or pneumatic cylinders.
  • the motor-gear unit preferably is equipped with a releasable brake.
