Definitions

  • the present invention relates to an elevator hoistway door separation preventive structure, and more particularly to an elevator hoistway door separation preventive structure, which prevents opening of hoistway doors by an external force and accidents caused by such opening of the hoistway doors through reinforcement of a door closure force when the hoistway doors are in a closed state.
  • elevator hoistway doors are installed in places where passengers can make direct contact with the doors rather than any other place of an elevator, and are exposed to passenger's mischief and accidents.
  • hoistway doors LD and RD are installed in a hoistway portion of an elevator, and upper portions of the hoistway doors LD and RD are connected to connection plates 400 of a hoistway door device.
  • the hoistway doors LD and RD have lower portions with respective shoes 100, and a sill 200, in which the shoes 100 are inserted and guided, is installed in the lower portions of the hoistway portion.
  • the door opening or closing operation is performed by operation of the connection plate 400 and guide operation of the shoes 100 and the sill 200.
  • the hoistway door device may have a structure in which the hoistway doors are connected together through a wire 300 or the like in the hoistway door device and if one door (e.g. LD) is moved, the other door (e.g. RD), which receives force transferred through the wire 300, is opened or closed, or a structure in which the respective connection plates are driven to operate.
  • the hoistway doors are closed, the upper portions of the doors are fixed to the connection plates 400 which are connected together through the wire 300.
  • the doors interlock with each other only when the doors move in the left or right direction, but on the rigidity or mass which supports the doors against pushing and lifting forces that occur when an impact is applied to a lower front surface of one door (e.g. LD), the other door (e.g. RD) exerts no effect.
  • the bending of the door occurs greatly, and thus the shoe 100, which serves to guide the lower portion of the door, may be separated from a groove 210 of the sill 200.
  • the present invention has been made to solve the above-mentioned problems occurring in the related art while advantages achieved by the related art are maintained intact.
  • One subject to be achieved by the present invention is to provide an elevator hoistway door separation preventive structure, which prevents separation of hoistway doors by additionally installing an attachment on a side surface of a door, sill, a door frame and making the door locked onto the sill or door frame by the attachment when the hoistway door is bent and a shoe is to be separated from a groove of the sill or the hoistway door is pushed backward.
  • an elevator hoistway door separation preventive structure which includes a first bracket formed on one end of a hoistway door arranged on a door frame; and a second bracket formed on one end of the door frame to correspond to the first bracket; wherein an end portion of the first bracket is bent toward the door frame to form a first stopper, and an end portion of the second bracket is bent to face the first stopper to form a second stopper, and the first and second stoppers are mutually engaged with each other when the hoistway door is closed.
  • the second stopper may have a groove formed thereon to make the first stopper inserted therein.
  • an elevator hoistway door separation preventive structure which includes a third bracket formed on one end of a hoistway door arranged on a door frame; and a third stopper formed on an end portion of the third bracket to be bent toward the door frame; wherein the door frame has a groove formed thereon to receive the third stopper inserted into the groove.
  • an elevator hoistway door separation preventive structure which includes a fourth bracket formed on one end of a hoistway door arranged on a door frame; and a fifth bracket formed on one end of the door frame to correspond to an upper portion that is upper than the fourth bracket; wherein a projection piece, which has a predetermined length and is positioned at a lower end of the fifth bracket, is formed at the front end of the fourth bracket.
  • an elevator hoistway door separation preventive structure including hoistway doors having lower portions on which shoes are installed, respectively, a sill formed on the lower portion of the door and having a groove formed thereon to guide the shoe, and an upper door frame formed on an upper portion of the door, which includes a sixth bracket installed on a side surface of the lower portion of the hoistway door and having a bent portion formed at the front end thereof; and a plate installed on a side surface of the sill so that the bent portion of the sixth bracket is locked onto the plate.
  • the bent portion may be in "U" shape seen from the above.
  • an elevator hoistway door separation preventive structure including hoistway doors having lower portions on which shoes are installed, respectively, and a sill having a groove formed thereon to guide the shoe, which includes a seventh bracket installed on a side surface of the lower portion of the hoistway door and having a bent portion formed at the front end thereof; wherein an elongated groove is formed on a side surface of the sill so that the bent portion of the seventh bracket is locked in the groove.
  • the bent portion may be in " ⁇ "' shape seen from the side.
  • an elevator hoistway door separation preventive structure including hoistway doors having lower portions on which shoes are installed, respectively, and a sill having a groove formed thereon to guide the shoe, which includes an eighth bracket attached to a lower portion of the sill and having a front end portion supported on an outer surface of the lower portion of the hoistway door.
  • the eighth bracket may include a horizontal portion fastened to the lower surface of the sill by a bolt, a vertical portion connecting with the horizontal portion and being in contact with the side surface of the sill, and the front end portion formed to be bent from a front end of the vertical portion.
  • the elevator hoistway door separation preventing structure adopts an attachment for preventing the separation of the hoistway door in the sill even if a strong impact or force is applied to the hoistway door, and thus can prevent a user or a resident from falling into the shaft.
  • FIGS. 3 and 4 are a front view and a plan view illustrating an elevator hoistway door separation preventive structure according to a first embodiment of the present invention.
  • an elevator hoistway door separation preventive structure includes a first bracket 5 formed on one end of a hoistway door 1 arranged on a door frame 4, and a second bracket 6 formed on one end of the door frame 4 to correspond to the first bracket 5.
  • An end portion of the first bracket 5 is bent toward the door frame 4 to form a first stopper 51
  • an end portion of the second bracket 6 is bent to face the first stopper 51 to form a second stopper 62, and thus the first and second stoppers 51 and 62 are mutually engaged with each other when the hoistway door 1 is closed.
  • FIGS. 5 and 6 are a front view and a plan view illustrating an elevator hoistway door separation preventive structure according to a modification of the first embodiment of the present invention.
  • an elevator hoistway door separation preventive structure includes a first bracket 5 formed on one end of a hoistway door 1 arranged on a door frame 4, and a second bracket 6 formed on one end of the door frame 4 to correspond to the first bracket 5.
  • An end portion of the first bracket 5 is bent toward the door frame 4 to form a first stopper 51
  • an end portion of the second bracket 6 is bent to face the first stopper 51 to form a second stopper 62
  • a groove 80 for inserting the first stopper 51 therein is further formed on the second stopper 62.
  • FIGS. 7 and 8 are a front view and a plan view illustrating an elevator hoistway door separation preventive structure according to a second embodiment of the present invention.

  • the door frame 4 has a groove 40 formed thereon to receive the third stopper 93 inserted into the groove.
  • the third stopper 93 is locked in the groove 40. Accordingly, when the hoistway door 1 is to be bent and pushed by an impact that is applied thereto, the bending, the pushing, and the lifting of the hoistway door 1 are suppressed by the locking between the third bracket 93 installed on the side surface of the hoistway door 1 and the groove 40 formed on the side surface of the door frame 4, and thus the shoe 3 is not separated from the sill 2.
  • FIGS. 9 and 10 are a front view and a plan view illustrating an elevator hoistway door separation preventive structure according to a third embodiment of the present invention.
