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.
  • a left door LD and a right door RD are installed in a hoistway portion of an elevator, and upper portions of the left door and the right door are connected to connection plates 400 of a hoistway door device.
  • the left door LD and the right door 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 doors When the 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.
  • EP 0 559 988 A1 is related to preamble of claim 1.
  • JP H03 79583 A shows an elevator door sill with a groove having walls which are inclined towards each other.
  • 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 the sill and hoistway doors without greatly increasing the strength of the hoistway doors to primarily secure a user's safety, and makes it possible for manufacturers to develop an inexpensive structure of the elevator to help the manufacturers.
  • an elevator hoistway door separation prevention structure having the features of claim 1.
  • an elevator hoistway door separation preventive structure including left and right doors having lower portions with respective shoes guided therein and a sill having a groove for guiding the shoes
  • a stepped portion is formed on a lower end of the shoe by bending the lower end of the shoes
  • a slit is formed on an inner surface of the groove of the sill to correspond to the stepped portion.
  • a stepped member is welded on a lower side surface of the shoe, and the slit that corresponds to the stepped portion is formed on the inner surface of the sill.
  • an elevator hoistway door separation preventive structure including left and right doors having lower portions with respective shoes guided therein and a sill having a groove for guiding the shoes
  • a bolt is fastened to the lower end of the shoe, and the slit that corresponds to the bolt is formed on the inner surface of the groove of the sill.
  • the stepped portion is formed by bending the lower end of the shoe, a slit is formed by cutting a bottom surface of the groove of the sill, and an inclined portion, which is in contact with the stepped portion, is formed on the end portion of one side of the slit.
  • a stepped member is formed to project from an outer surface of the lower end of the shoe, an inclined surface is formed on one side of the inner portion of the groove of the sill, and a vertical surface is formed on the other side of the groove, wherein an upper portion of the groove is formed to be narrow and a lower portion of the groove is formed to be wide.
  • a stepped member is formed to project from the outer surface of the lower end of the shoe, and inclined surfaces are formed on both sides of the inner portion of the groove of the sill in the same direction.
  • an overlay member having a tetragonal cross section is installed on the outer surface of the lower end of the shoe, wherein if the shoe is bent over a predetermined angle, corners of upper and lower ends of the overlay member are in frictional contact with the groove so that the shoe is not separated from the groove.
  • the shoe is formed to have a rectangular cross section with a predetermined thickness and to be in close contact with the inner surface of the groove, wherein if the shoe is bent over a predetermined angle, the outer surface of the shoe is in frictional contact with the groove so that the shoe is not separated from the groove.
