Definitions

  • the subject disclosure relates generally to a horizontal side -rolling fabric door and more specifically to a pliable frame cover for such a door.
  • 4,096,902 includes one or two vertical rollers at either one or both lateral edges of the doorway.
  • Some horizontal side-rolling doors have a single roller at one side of the doorway with a single curtain that extends and retracts across the full width of the doorway.
  • the "single curtain" is actually comprised of two layers, each having its own vertical take-up roller.
  • the two rollers are right next to each other at one lateral edge of the doorway.
  • the two layers of the curtain separate at the edge of the doorway and wrap upon their respective rollers.
  • Other horizontal side-rolling doors include two individual curtains, each supported by its own roller at opposite lateral edges of the doorway.
  • the two separate curtains meet at the center of the doorway as the door closes.
  • the two curtains move apart from each other and wrap upon their own roller (or set of rollers if each curtain has two layers).
  • the curtain rollers are typically housed within some type of enclosure. Such enclosures, however, can make it difficult to access the roller for repair or other service operations.
  • the enclosures are also susceptible to damage by way of direct impact from a vehicle passing through the doorway or by way of indirect impact if the vehicle strikes the curtain.
  • the leading edge of the curtain typically is reinforced by a rigid structural member Patent Application Atty. Docket No. 92/D08-006A PCT that is used for closing the door and for holding the leading edge substantially straight and upright. When that structural member is struck in a certain direction, the curtain might forcibly push against the enclosure components, interfering with full curtain movement and potentially damaging the curtain components or enclosure.
  • FIG. 1 is a front view a horizontal side-rolling door shown in a closed position.
  • FIG. 2 is a front view of the door of FIG. 1 but showing the door open.
  • FIG. 3 is a cross-sectional view taken along line 3-3 of FIG. 2, wherein a shroud is in an installed position.
  • FIG. 4 is a cross-sectional view similar to FIG. 3 but showing the shroud in a retracted position.
  • FIG. 5 is a cross-sectional view similar to FIG. 4 but showing the shroud completely removed from its supporting frame.
  • FIG. 6 is a front view of the shroud and roller at the left side of FIG. 2.
  • FIG. 7 is a cross-sectional view taken along line 7-7 of FIG. 6.
  • FIG. 8 is a front view similar to FIG. 6 but showing the shroud moving from the installed position to the retracted position.
  • FIG. 9 is a cross-sectional view taken along line 9-9 of FIG. 8.
  • FIGS. 1 and 2 show a horizontal side-rolling door 10 with at least one curtain 12 that moves horizontally across a doorway 14 to open and close the door.
  • door 10 includes two curtains 12 and 16 supported by spring-loaded rollers 18 installed in proximity with lateral edges 20 of doorway 14.
  • a preloaded torsion spring 22 Patent Application Atty. Docket No. 92/D08-006A PCT urges each roller 18 to rotate in a direction that tends to draw in and wrap the respective curtain 12 or 16 onto itself.
  • An overhead track 24 and drive unit 26 coupled to rigid support members 30 at the leading edges of curtains 12 and 16 are used for opening and closing the door 10.
  • FIG. 1 shows door 10 closed with the curtains' 16 leading edges abutting each other near the center of doorway 14, and
  • FIG. 2 shows door 10 open with most of the curtains wrapped around rollers 12 and 16.
  • roller 18 is supported by a frame comprising a base 32 on floor 34, a back frame member 36 attached to wall 38, and an upper bracket 40 (FIG. 1) extending from frame member 36. Both rollers 18 are supported in a similar manner.
  • a shroud 42 made of pliable material extends from back frame member 36 over to an edge frame member 44.
  • Edge frame member 44 is removably coupled to base 32 and upper bracket 40, as will be explained in more detail below. Since shroud 42 is made of a pliable material, it is preferably stretched taut when edge frame member 44 is coupled to base 32 and upper bracket 40 to give shroud 42 a flat and neat, unwrinkled appearance. The pliability of the shroud material also allows the shroud 42 to absorb direct minor impact by flexing.
  • Shroud 42 can be made of any suitable material including, but not limited to, a natural material or a synthetic fabric material, a plastic sheeting, and various layers and/or combinations thereof.
  • the shroud material can be optionally coated and/or impregnated with any suitable material such as, for example, various polymers, to give the shroud material desirable properties such as, for example, being antimicrobial.
  • a corner frame member 46 coupled to base 32 and bracket 40 helps hold shroud 42 in a generally L-shaped configuration, as viewed in FIG. 3.
  • a touch-and-hold fastener 48 (e.g., VELCRO®) can be used for attaching a proximal end 50 of shroud 42 to back frame member 36; however, numerous other ways of affixing proximal end 50 can certainly be used.
  • edge frame member 44 is tubular (e.g., a steel pipe) and is installed within a looped section 56 of shroud 42. Frame member 44 may be loosely held within loop 56 to allow member 44 to be readily removed and replaced without damage. Edge frame member 44 is held in place between an upper pin 58, extending downward from bracket 40, and a lower anchor 60 in the shape of a Patent Application Atty. Docket No.
  • edge frame member 44 is relatively stiff, its limited flexibility and axial clearance 62 under bracket 40 allows member 44, when impacted, to flex and move up and off of anchor 60, as shown in FIGS. 8 and 9.
  • the ability of edge frame member 44 to break away in such a manner when a force exceeding a threshold magnitude is applied may be enhanced by providing anchor 60 with a tapered upper surface 64 (FIG. 7).
  • Surface 64 could be conical, hemispherical, rounded, or any other suitable shape to promote breakaway action in any direction, or surface 64 could face just certain directions so that edge frame member 44 breaks away in some directions easier than others.
  • tapered surface 64 generally faces wall 38 to promote breakaway action from that direction.
  • Corner frame member 46 can be mounted in a similar manner.
  • the breakaway feature may not be as important in this area, thus corner frame member 46 in a tubular form
  • bracket 40 e.g., a pipe
  • Clearance 70 under bracket 40 allows corner frame member 46 to be readily installed and replaced, for example, by simply lifting member 46 up and over lower pin 68.
  • edge frame member 44 and anchor 60 allows shroud 42 to be moved manually from an installed position of FIG. 3 to a retracted position of FIG. 4.
  • shroud 42 can be completely removed as shown in FIG. 5.
  • door 10 includes a seal 72 (FIGS. 3 and 4) that runs substantially the full height of curtain 12.
  • Seal 72 may be a flexible loop that is sewn or otherwise attached to an inner surface of shroud 42. When shroud 42 is in the installed position of FIG. 3, a central portion of the seal's 72 loop sealingly engages a face of curtain
  • a flexible end seal 74 may be attached to each of the leading edges of curtains 12 and 16 so that seals 74 abut each other when door 10 is closed.
  • At least some of the aforementioned examples include one or more features and/or benefits including, but not limited to, the following:
  • a horizontal side-rolling door includes a flexible shroud that shields the door curtain's take-up roller.
  • the shroud both shields and seals a curtain extending from a roller.
  • a door curtain roller is shielded by a shroud that is supported by a resiliently flexible breakaway frame.
  • a door curtain roller is shielded by a shroud that is selectively movable between an installed position and a retracted position.
  • a door curtain roller is shielded by a shroud that is supported by frame members that can be readily replaced without the use of tools.
  • a door curtain roller is shielded by a shroud assembly that can break away without significant permanent damage.
  • the shroud assembly can break away in certain directions easier than others.
