Definitions
- This invention relates to improvements in Roller Doors.
- Rollers Doors are doors which are widely used in Australia as garage doors and may be formed out of a sheet of metal which can be selectively deformed or may be formed of a number of interlocking sheets, each of which have a height substantially less than the diameter of the roller about which the shutter passes, so they can be located around the roller when the shutter is in its open position and be closely fitting to the roller.
- roller be located as close to the ceiling or area above the door and as close outwardly to the opening, so that the shutter is basically downwardly directed when the roller is fully retracted.
- the invention includes a roller door having a seal means which is attached to the door shutter at a location such that when the door is in its closed condition, the seal extends from the face of the door and extends outwardly therefrom and contacts the door sill and, when the door is opened, the seal means is caused to be located between the portion of the shutter to which it is connected and the portion of the shutter which lies directly thereover, characterised in that the seal means is of such a form that when so located it has little effect on the form of the rolled shutter.
- the seal means is formed of an extrusion of a resilient material which, when unconstrained has a substantial depth extending outwardly of the door but which can reduce to a minimal depth when pressure is applied thereto.
- the seal is preferably a strip of resilient material having two sides which are adapted to be connected to the shutter, the sides, when connected, being located parallel to one another and a body portion between the sides which, when the sides are connected extend outwardly from the sides in a generally U-shaped configuration.
- Each sides may include an enlarged portion which is formed to cooperate with a member having a recess transverse to the shutter and extending substantially along the width thereof.
- Fig 1 shows a front view of a roller door of a conventional form to which the invention may be applied:
- Fig 2 shows a rear view of the door of Fig 1, the door being closed;
- Fig 3 shows a seal of a type which may be used in association with the invention
- Fig 4 shows a side view, with the sill in section, of the roller and shutter of the door with the seal in location;
- Fig 5 is a view similar to that of Fig 5 wherein there is a larger gap between the seal and the shutter of the door.
- Figs 1 and 2 show a conventional roller door having a door opening 10 which can be considered to have two sides, or jambs 11,12, and a sill 13, and these are normally define an opening which is square or rectangular and of the depth of either the frame or the building.
- the door has a roller 20 which extends across the width of the opening 10 above the sill 13.
- the axis of the roller 20 may be at the level of the sill, or even very slightly there below.
- the roller has a central axis 21 and means such as a motor and gearbox or chain drive (not shown) whereby it can be rotated in either direction.
- a track means 14,15 which is adapted to receive the door shutter 22 which can be rolled onto the roller 20, to open the door or the be unrolled therefrom, to close the door.
- These tracks may, at their upper ends, be deformed to provide an arcuate surface 16 over which the shutter can pass as it moves from the roller 20 into the track 14,15.
- the shutter itself may be formed of a panel of a relatively light metal which is deformed longitudinally to give rigidity to the panel whilst enabling bending about a transverse axis, so that the panel can be located about the roller.
- the shutter can be made of panels formed to inter-engage one with the other, so as there can be rotational movement between these.
- the height of these panels can be relatively small, relative to the diameter of the roller about which they are to pass, so that as the door is opened, the panels can locate closely around the roller.
- the panels, in section, flat portions 23 which are outwardly directed and smaller inwardly directed flat portions 24 which are interconnected which arrangement gives a substantial degree of rigidity along the width of the door, whilst permitting a certain flexibility along the height of the door.
- the arrangement also gives as aesthetically pleasing appearance and can assist in passing the panel over the roller 20.
- rubbing strips On each side of the panels there are located rubbing strips, not illustrated, which may be of a fabric-type material and which serve two purposes.
- these strips provide a spacer to prevent adjacent turns of the shutter from being in contact one with the other on the roller with the inevitable damaging of the surface of the shutter which is to be directed outwardly when the door is closed, and thus marring the surface.
- the invention provides, on one of the flat outwardly-directed surfaces 23 of the shutter at a position adjacent the sill 13, when the shutter is closed, a seal member 30 which is continuously located across the width of the shutter and connected thereto.
- seal member 30 is an extrusion of rubber, synthetic rubber or a plastics material which has a body portion 31 at each end of which there are a plurality of extension members 32, 32a ... Also on the body portion 31 has a number of outwardly directed flaps 34 which extend along the length of the seal and are parallel and of the same height.
- the extension members 32 ... are adapted to cooperate with an extrusion 40 which is fitted to, or could be formed into the shutter 22 of the door.
- the extrusion 40 which may be a single extrusion or a pair of extrusions are located on one of the flat portions 23 of the shutter.
- Figs 4 and 5 The seal, as can be seen from Figs 4 and 5 is connected between the two recesses in the extrusion and extends outwardly from the face of the shutter.
- Figs 4 and 5 differ from each other and demonstrate how the seal of the invention can be used with doors in which the rollers are different spacing from the sill 13.
- Fig 3 all of the extension members, other than the one which is in connection with the body are removed where the roller is close to the sill.
- Fig 4 shows an arrangement where there is a substantially larger spacing.
- FIGS. 3, 4 and 5 illustrate one form of seal, it is to be understood that various other forms of seal can also be completely satisfactory.
- the seal could have a relatively flat base with a seal member extending outwardly therefrom. If a seal of this form is used, the base could be connected directly to the shutter face.
- the connection is preferably an adhesive connection so that the seal is in close abutment with the shutter across the whole of the width thereof.
- the seal may take various shapes, but preferably, in section, has the flat surface which is adapted to be connected to the shutter and an outwardly-directed portion which, in a preferred form, may be a circular arc or some similar closed shape connected at each side to the edges of the flat portion, so that there is an enclosed open portion when the seal is in its normal position, but pressure on the extending portion can simply permit the seal to collapse, so that the circular other shaped portion can be brought into a position where it is closely abutting the flat portion.
- the seal may preferably be made from a single extrusion of an artificial rubber or synthetic plastics material, the flat face portion may have a thickness greater than the remainder, so that the seal itself has an overall rigidity and the outwardly extending portion can be of a thickness sufficient to enable mechanical working over a long period, but also such that the portion can be collapsed on the flat face portion without great difficulty and without extending outwardly substantially therefrom.
- the seal is located across the appropriate flat portion of the shutter, so that when the shutter is closed, the seal extends across the gap and comes into contact with the sill and makes a seal therewith.
- the body of the seal adopts a generally U-shape with the extensions 34 forming flaps to make contact with the inner surface of the sill.
- the seal will move around the roller until it comes into a position where a portion of the shutter is going to lie thereover and the arrangement is such that the shutter portion causes the seal to be deformed inwardly.
- the total height of the seal may be substantially the same as the spacing between the two panels, keeping in mind that they are separated by the rubbing strips and, as such, the seal does not substantially affect the profile of the shutter as it is being rolled upon the roller.
- the rolled shutter effectively has the same dimensions as a shutter without the seal, so there is no necessity to relocate the roller to take into account any deformation or distortion of the profile of the rolled shutter caused by the seal.
- the invention provides the door which, when raised, shows no indication whatsoever of sill-seal, but which, when lowered, provides a neat and unobtrusive seal. This is aesthetically more pleasing than was the case where seals were located on the sill, so that they were always visible.
- the seal is also effective right across the width of the panel of the shutter and can extend between the rubbing strips on either side and, if required, could also extend up to and over the rubbing strip, although this may not be preferred.
- the seal could be a block of a soft sponge-type material which would, when unconstrained, extend from the shutter to the sill, but when the shutter is being rolled, the seal could simply be permitted to collapse to be received, as described earlier between the rubbing strips.
