Definitions

  • the present invention relates an overhead door structure.
  • motorized overhead doors have been known to present a danger to people and/or things.
  • a first dangerous situation occurs when a person accidentally laterally insert its arm or hand between the rotation rod and the door being closed, because the rotation rod, being rigid, act as a scissors, eventually shearing the arm or hand.
  • a second dangerous situation occurs when people and/or things, especially young children, are in the vicinity of the door while it is being closed because they may be subject to possible injury by the impact of the weight of the door in its downwards travel.
  • One type of commercially available safety device provides a sensor, which trigger or interrupt the circuitry which power the door to remove the power and therefore arrest the door in its downwards travel in the event an obstacle, such as people and/or things, is in the path of the door while it is closing.
  • the above mentioned solution is not completely satisfactory, a drawback thereof being the delay time between the sensing of the obstacle in the path of the closing door and the cutting off of the power to the drive member, e.g. a motor.
  • the drive member e.g. a motor.
  • the worst case of a malfunction of the sensor it can happen that the overhead door does not arrest its downwards travel with consequent heavy impact and damages to people and/or things.
  • the main object of the present invention is to provide an overhead door structure provided with a safety device such that the overhead door yieldingly abut against a possible obstacle to be found in the path of the door while being closed.
  • Another object of the present invention is to provide an overhead door structure that is easy and reliable in operation and can be manufactured at competitive production cost.
  • an overhead door structure including a fixed frame to be secured in a door opening, two lateral vertical guides formed in fixed frame, an overhead door slidingly constrained to lateral guides at a lower portion thereof and provided with articulation means to fixed frame at an upper portion thereof, and drive means arranged to actuate the overhead door between a closed position in which said overhead door fully close said door opening and an opening position in which the overhead door clears said door opening and is positioned at an upper portion of, and transversely to, said fixed frame, characterized in that articulation means comprises at least one flexible connecting member having one end thereof secured to said frame and its other end secured to an upper portion of said overhead, whereby said overhead door yieldingly abuts against a possible obstacle to be found in the path of said overhead door while being closed.
  • a prior art overhead door structure comprises a fixed frame 10 including two vertical uprights 20 formed with respective fixed vertical guides 30 along which a respective pin or roller 40 secured to a lower portion of an overhead door 50 can slide.
  • each vertical upright 20 carries a bracket 60 bearing a rotatable pulley 70 around which a respective cable 80 carrying a respective counterweight 90 can turn.
  • the other end of the cable 80 is anchored to an intermediate portion of a respective side of the overhead door 50.
  • an articulation rod 110 is provided, having one end thereof pivoted to a pin 120 projecting from an upper portion of the fixed frame 10 and its other end articulated to a pin 130 at an upper portion of the overhead door 50.
  • the overhead door 50 at its upper portion is laterally constrained by the articulation rod 110, whereas at its lower portion by means of pin or roller 40 it is slidably movable along fixed vertical guides 30.
  • the overhead door 50 can thus be raised to its open overhead position and lowered to its closed position either by an operator acting manually onto the overhead door or by an actuation or drive means, e.g. a reversible electric motor, for the pulleys 70, i.e. for each cable 80 acting at an intermediate side portion of the overhead door 50.
  • An overhead door structure 1 as shown in Figures 2 and 3 comprises two vertical uprights 2 having a respective vertical guide 3 along which a pin or roller 4 projecting from a lower portion of an overhead door 5 can slide.
  • Each vertical upright 2 carries at the top thereof a bracket 6 on which a pulley 7 is mounted for rotation.
  • a cable 8 turns around each pulley 7, one end of each cable carrying a respective weight 9, whereas its other end is secured to an intermediate side portion, e. g. a projecting pin 10, of overhead door 5.
  • a flexible connecting member 11, e.g. one or two cables, preferably metal cables, one or two chains, or a linkage system, has one end thereof anchored to an upper portion, e.g.
  • the overhead door 5 is constrained by the flexible connecting member 11 at its upper portion, by means of a pin or roller 4 sliding along a respective vertical guide 3 at its lower portion, and by one end of a cable 8 carrying the counterweight 9 at its intermediate portion.
  • Figures 2 and 3 show the closing or lowering movement of a motorized overhead door structure according to the invention and the event in which an obstacle O (see Fig. 3) is found in the path of the overhead door 5.
  • the overhead door 5 Upon abutting against obstacle O the overhead door 5 can yield backwards and upwards while damping the impact between obstacle O and overhead door 5 by carrying out a composite rotational and displacement movement as illustrated by arrows R and D in Fig. 3, backwards rotational movement (arrow R) being allowed by flexible connecting member 11, whereas upwards displacement movement (arrow D) is carried out by pins or rollers 4 sliding along their respective vertical guides 3.
  • the zones B are no longer dangerous, since, in the event an obstacle, e.g. an arm or an hand, is present in zone B, when the overhead door, during its lowering movement, abuts against such an obstacle, the flexible connecting member 11 yields backwards, thereby preventing any shearing effect.
  • an obstacle e.g. an arm or an hand
  • sensor means e.g. a micro or proximity switch, is provided which is arranged to detect such an upwards movement of the overhead door and stop or preferably invert the rotation of the motor.
