Definitions

  • the present invention is directed to an apparatus configured for use with a door or other barrier for maintaining the door or other barrier in a position and capable of resisting a trans-­barrier force less than a predetermined magnitude.
  • the apparatus is designed to yield and allow the barrier to move in response to the trans-barrier force, thereby avoiding damage to the barrier and, further, avoiding damage to adjacent supporting structures for the barrier, such as guide rails, supports, tensioning mechanisms, and the like.
  • the preferred embodiment of the present invention is particularly adaptable for use with a door of the roll-up type which is generally used for environmental control between two spaces, such as between sections of a warehouse, or the like.
  • a motor-driven roller controls the upward and downward movement of the door to control access through an opening.
  • An assembly of cables, associated pulleys, and tension springs serves as a tensioning mechanism.
  • the tensioning mechanism is driven by the roller motor and connected to a guide follower apparatus.
  • the guide follower apparatus is attached to the bottom, or leading edge, of the roller door and interacts with guide rails adjacent the opening.
  • the door is generally flexible and is kept under tension to aid in maintaining alignment of the door with respect to the guide rails and the opening.
  • the hinged guide rail solution had problems and shortcomings: the cables in the door tensioning mechanism could snarl, stretch, break, or otherwise become damaged; associated pulleys and tension springs of the tensioning mechanism could similarly be damaged; and, perhaps most important, since the guide rails were generally placed adjacent the opening, as opposed to within the opening, the hinged guide rail only accommodated trans barrier forces in one direction, away from the wall surrounding the opening. Trans-barrier forces applied in the opposite direction (toward the wall) would not operate to pop open the hinged panel of the guide rail and would serve only to drive the door and its associated guide follower against the wall surrounding the opening. Of course, driving the door against the wall caused damage to the guide follower, door, guide rail, tensioning apparatus, and other parts of the door installation.
  • the present invention is designed to overcome the shortcomings of these previous attempts to provide a trans-barrier force accommodation mechanism to avoid damage to a barrier and its associated structures and mechanisms.
  • the present invention uses a structure which accommodates trans-barrier forces in two directions.
  • the invention is an apparatus configured for maintaining a barrier in a position against a trans-barrier force less than a predetermined magnitude.
  • the barrier has associated structures for cooperating with the apparatus to define the position in which the barrier is maintained.
  • the apparatus comprises a guide follower attached to the barrier and operatively interactive with the associated structures for defining the barrier position.
  • the guide follower of the apparatus comprises a first portion attached to the barrier and a second portion operatively interactive with the associated structures.
  • the first portion and the second portion are in an interfitting relation and define at least one pair of mating surfaces, each of which mating surfaces is transverse to the barrier and oriented to allow sliding disengagement of the first portion and the second portion in response to application of a trans-barrier force to the barrier in excess of a predetermined magnitude.
  • the present invention therefore, maintains the barrier, such as a roll-up door, in a desired position with respect to the associated structures of the barrier and with respect to the opening through which access is controlled by the barrier.
  • the apparatus of the present invention By using the apparatus of the present invention to effect the operative interaction between the barrier and its associated structures, trans-barrier forces applied against the barrier can be accommodated up to a predetermined magnitude without affecting the door.
  • the apparatus of the present invention will yield by slidingly disengaging the first portion and the second portion of the apparatus to allow the barrier to be displaced in response to the trans-­barrier force. In such manner, the trans-barrier force is not transmitted to the associated structures of the barrier so that damage to the associated structures is avoided.
  • the predetermined force at which the first portion and the second portion of the apparatus will disengage may be definitively established by the structure of the apparatus.
  • a shear pin may be employed in a manner whereby the shear pin intersects at least one of the mating surfaces defined by the interface of the first portion and the second portion of the apparatus.
  • the shear pin can be designed to shear in response to a force which can be precisely determined by the material, diameter, and other parameters of the shear pin.
  • an object of the present invention to provide an apparatus for maintaining a barrier in a position against a trans-barrier force less than a predetermined magnitude, and enabling displacement of the barrier in response to a trans-barrier force in excess of that predetermined magnitude without causing damage to the barrier or to barrier-associated structures.
  • a further object of this invention is to provide an apparatus for maintaining a barrier in a position against a trans-barrier force less than a predetermined magnitude which can respond to trans-barrier forces in two directions with respect to the barrier without occasioning damage to the barrier or to barrier-associated structures.
  • Yet a further object of the present invention is to provide an apparatus for maintaining a barrier in a position against a trans-barrier force less than a predetermined magnitude in which the predetermined magnitude can be established with accuracy.
  • Fig. 1 illustrates the principal elements of a roll-up door assembly 10 in an exploded perspective view.
  • the roll-up door assembly 10 principally consists of a roller 12 directly driven by a motor 14. On the roller 12 is the flexible door 16 and cable reels 18.
  • the roller 12 is situated adjacent an opening 20 in a wall 22. Adjacent the opening 20 and mounted to the wall 22 are guide rails 24.
  • the door 16 is rolled and unrolled upon the roller 12 in response to movement of the roller 12 by the motor 14.
  • the door 16 is maintained in a position adjacent the opening 20 by the guide rails 24, in a manner to be described in greater detail hereinafter.
  • a top view of a prior art guide rail 24 is illustrated attached to a wall 22.
  • the guide rail 24 comprises a wall 26 of generally L-shape with a first leg 28 affixed to the wall 22 and a second leg 30 depending from the first leg 28.
  • a cover 32 is hinged to the second leg 30 at a hinge 34.
  • the cover 32 presents a guide wall 36 in facing relation to a guide wall 38 depending from first leg 28.
  • the guide walls 36 and 38 define a channel 40 which leads from without the guide rail 24 to an interior chamber 42 defined by the wall 26 and the cover 32.
  • the door 16 and its associated guide follower slidingly travel within the channel 40 so that the guide rail 24 guides the door 16 in a desired orientation with respect to the opening 20 as the motor 14 rotates the roller 12 to move the door 16 upward and downward within the channel 40.
  • the interior chamber 42 contains the tensioning mechanism (not shown in Figs. 1 and 2) in a manner to be described in greater detail hereinafter.
  • the guide rail 24 of Fig. 2 responds to application of a trans-barrier force F applied to the door 16 in a direction away from the wall 22 as follows: as the trans-barrier force F is applied to the door 16, the door 16 will impinge upon the guide wall 36, urging the cover 32 to rotate about the hinge 34 in a direction as indicated by the arcuate arrow R in Fig. 2. Thus, the door 16 will no longer be resisted in its movement in the direction of the arrow F in Fig. 2 by the guide wall 36 and will, therefore, freely swing away from the wall 22 in response to the trans-barrier force F.
  • FIG. 3 A serious shortcoming of the prior art design illustrated in Figs. 1 and 2 is best illustrated in Fig. 3, a more detailed illustration of one side of a roll-up door assembly 10.
  • the guide rail 24 is illustrated with the cover 32 removed to reveal the details of the tensioning mechanism 44.
  • the tensioning mechanism 44 includes a cable 46 which is attached at a first end 48 to the cable reel 18 on the roller 12.
  • the cable is led through pulleys 50, 52, and 54 and terminates at a second end 56.
  • the second end 56 is attached to an extension arm 58 of a guide follower 60.
  • the guide follower 60 is attached to the door 16.
  • a tension spring 62 is attached between the pulley 50 and a tab 64 associated with the guide rail 24 to maintain the cable 46 in tension.
  • the door 16 and the guide follower 60 extend beyond the inner edge 25 of the guide rail 24.
  • the inner edge 25 is the closest edge to the door 16 of the first leg 28 of the guide rail 24, which first leg 28 is attached to the wall 22 adjacent the opening 20.
  • the inner edge 25 is substantially co-terminous with one end of the channel 40.
  • the cover 32 of the guide rail 24 is not illustrated in Fig. 3, it can be plainly seen from Fig. 3 that the door 16 and its attached guide follower 60 extend through the channel 40 to the interior chamber 42 of the guide rail 24 in its travel upward and downward in response to rotation of the roller 12 by the motor 14.
  • Fig. 4 illustrates a perspective view of the preferred embodiment of the present invention.
  • a flexible door 16 is illustrated with a leading edge segment 64 attached at the bottom of the flexible door 16.
  • the leading edge segment 64 extends the full width of the flexible door 16 and is attached to a guide follower 66.
  • the preferred embodiment of the guide follower 66 includes a pair of U-shaped brackets 68 and 70 oriented in facing relation and embracing a sliding block assembly 72.
  • the sliding block assembly 72 is comprised of two portions 72a and 72b of material preferably having a low coefficient of friction, such as urethane or the like, and joined in a multi-dovetail joint 74.
  • the U-shaped bracket 68 may be unitarily formed with the leading edge segment 64 or may be attached by bolting, adhesive, or other commonly known means to the leading edge segment 64.
  • a guide follower arm 76 may be similarly unitarily formed with the U-shaped bracket 70 or attached to the U-shaped bracket 70.
  • the guide follower arm 76 extends substantially perpendicularly from the U-­shaped bracket 70 and is configured to slidingly engage a guide rail structure adjacent an opening and accommodate a tensioning mechanism in the manner previously known and illustrated in Figs. 1-­3.
  • a shear pin 78 configured to be inserted in an aperture 80.
  • the aperture 80 is oriented to intersect the dovetail joint 74 substantially throughout the length of the dovetail joint 74 so as to intersect the mating surfaces established at the boundaries of the sliding block assembly portion 72a and sliding block assembly portion 72b, as will be described in greater detail hereinafter.
  • the sliding block assembly 72 is retained between the facing U-shaped brackets 68 and 70 by means generally known in the industry, such as bolting (not shown in Fig. 4), adhesive, or the like.
  • Fig. 5 illustrates a plan section view of the sliding block assembly of the preferred embodiment of the present invention.
  • the sliding block assembly 72 is held between the two U-shaped brackets 68 and 70 and the dovetail joint 74 establishes pairs of mating surfaces 82a-­82i.
  • the plurality of mating surfaces 82a-82i are substantially perpendicular to the two faces 84 and 86 of the sliding block assembly 72.
  • the sliding block assembly 72 will separate into a first portion comprising U-shaped bracket 68 and sliding block assembly portion 72a and a second portion comprising U-shaped bracket 70 with its attached guide follower arm 76 and sliding block assembly portion 72b upon application of a force, for example, against the leading edge segment 64 of the door 16 in either of the two directions substantially perpendicular to the leading edge segment 64.
  • a force for example, against the leading edge segment 64 of the door 16 in either of the two directions substantially perpendicular to the leading edge segment 64.
  • a fork lift or other machine impacting the leading edge segment 64 of the door 16 from either side of the door 16 will, if the force is of sufficient magnitude, shear the shear pin 78 (referring to Fig. 4) and effect a sliding disengagement of the two portions 72a and 72b of the sliding block assembly 72.
  • the material of the sliding block assembly 72 is selected to provide a minimal coefficient of friction in order that minimal amounts of the trans-barrier force applied to the leading edge segment 64 will be transmitted through the sliding block assembly 72 to the guide follower arm 76.
  • the guide follower arm 76 will impact a minimal amount on its associated guide rail and tensioning mechanism, thereby precluding damage to the guide rail and tensioning mechanism.
  • the aperture 80 is clearly shown as passing entirely through the sliding block assembly 72 and intersecting pairs of mating surfaces 82b, 82d, 82f, and 82h.
  • Proper selection of the shear pin material, diameter, and other parameters serves to precisely define the amount of trans-barrier force which must be applied to the sliding block assembly 72 in order to effect sliding disengagement of sliding block assembly portion 72a and 72b.
  • Fig. 7 illustrates an alternate embodiment of the apparatus of the present invention in the form of an alternate top view of the sliding block assembly illustrated in Fig. 5.
  • the pairs of mating surfaces 82 are not perpendicular to the faces 84 and 86 of the sliding block assembly 72, and, thus, the sliding block assembly 72 will only slidingly disengage in one direction in response to a trans-barrier force.
