Definitions

  • the subject matter disclosed herein generally relates to sliding doors and, more particularly, to anti-derailment systems for sliding doors, and in some embodiments, elevator system sliding doors.
  • Elevator systems include sliding doors, both of the elevator car and at the landings. Such doors must be structurally sound and securable to prevent unauthorized access to an elevator shaft of the elevator system. Locks and locking mechanisms are typically employed to secure the sliding landing doors of an elevator system to prevent unauthorized opening of the sliding doors. However, the sliding doors must also be designed to prevent forced opening, such as by impact to the doors. Accordingly, in typical systems, the landing doors (and elevator car doors) can be manufactured with stiffeners or other structural components that provide additional strength to the sliding doors. Such strength prevents impacts from pushing the sliding doors inward, and potentially having a portion of the landing door "jump" from a track through which the sliding door is guided. The stiffeners will add additional costs, weight, and installation considerations, and thus improved sliding doors may be advantageous.
  • sliding door systems include, a sliding door having a structural panel, a sill having a guide channel, wherein at least a portion of the structural panel is positioned within and movable through the guide channel, and an anti-derailment system.
  • the anti-derailment system includes a panel extension extending from the structural panel, the panel extension located within the guide channel and a stop fixedly attached to the sill and located within the guide channel, wherein when the sliding door is in a closed position the panel extension is positioned proximate to the stop.
  • further embodiments of the sliding door systems may include that the stop is integrally formed with the sill.
  • further embodiments of the sliding door systems may include that the stop is fixedly attached to the sill by a fastener.
  • further embodiments of the sliding door systems may include that the stop further comprises a sleeve, wherein the sleeve fits within the guide channel and the fastener passes through the sleeve to fixedly hold the sleeve within the guide channel.
  • further embodiments of the sliding door systems may include that the panel extension comprises an extension contact surface, wherein, when the sliding door is subject to an impact, the extension contact surface will contact the stop to prevent the structural panel from leaving the guide channel.
  • further embodiments of the sliding door systems may include a guide shoe installed on the structural panel and arranged to guide the structural panel within the guide channel.
  • further embodiments of the sliding door systems may include that the sliding door is a center closing sliding door, wherein the stop is positioned in a center of the sill.
  • sliding door systems may include that the sliding door is a sliding door of an elevator system
  • further embodiments of the sliding door systems may include that the sliding door is an elevator landing door of the elevator system.
  • further embodiments of the sliding door systems may include that the sliding door is an elevator car door of the elevator system.
  • further embodiments of the sliding door systems may include that the sliding door is a sliding door of a vehicle.

  • the roping 107 engages the machine 111, which, in this illustrative embodiment, is part of an overhead structure of the elevator system 101, although other arrangements are possible without departing from the scope of the present disclosure.
  • the machine 111 is configured to control movement between the elevator car 103 and the counterweight 105.
  • the position encoder 113 may be mounted on an upper sheave of a speed-governor system 119 and may be configured to provide position signals related to a position of the elevator car 103 within the elevator shaft 117. In other embodiments, the position encoder 113 may be directly mounted to a moving component of the machine 111, or may be located in other positions and/or configurations as known in the art.
  • the elevator controller 115 is located, as shown in the illustrative arrangement, in a controller room 121 of the elevator shaft 117 and is configured to control the operation of the elevator system 101, and particularly the elevator car 103. In other embodiments the controller 115 can be located in other locations, including, but not limited to, fixed to a landing or landing door or located in a cabinet at a landing.
  • the elevator controller 115 may provide drive signals to the machine 111 to control the acceleration, deceleration, leveling, stopping, etc. of the elevator car 103.
  • the elevator controller 115 may also be configured to receive position signals from the position encoder 113.
  • the elevator car 103 may stop at one or more landings 125 as controlled by the elevator controller 115.

  • the landing door sill 233 includes a guide, groove, or similar structure that is arranged to receive part of the landing door 231 to guide operation of the landing door 231.
  • landing doors of elevator systems are designed to withstand impacts to prevent forced entry or opening of the elevator landing doors, and thus prevent improper access to an elevator shaft.
  • impact/shock resistance is provided for elevator landing doors to provide safety to passengers and prevent falls into the elevator shafts.
  • the landing doors are arranged to remain in place and act as a barrier when the landing doors are closed.
  • landing doors are reinforced with additional or heavy structural paneling that provides stiffness and strength to withstand impacts.
  • landing doors are typically made from relatively thin sheet metal thickness (e.g., 1.5 mm). Due to the thin metal of such landing doors, the panels typically require stiffeners or other structural reinforcement elements to withstand shocks and/or impacts.
  • a stop located in the sill of the landing door system can be provided that enables increased strength or resistance to an elevator landing door at the time of an impact or shock.
