  • Modular sliding member power mechanism and method for its operation Field of technology locks; doors; windows.
  • Technical problem to be solved with the present invention is providing for easier maintenance of power sliding door mechanism, current mechanisms are subject to significant maintenance operations during malfunctions, and also for easier installations. Further technical problem to be solved is simplification of disengaging of sliding member to sliding member power mechanism.
  • Patent EP2100777 describes power supply apparatus for a sliding door.
  • the power supply apparatus includes a body-side fixture mounted on an automobile body, a door- side fixture mounted on the sliding door, and a flat cable gripped in the body-side fixture and the door-side fixture for supplying a power to the sliding door.
  • the flat cable is pulled out from the body-side fixture and/or the door-side fixture to form a convex flexural portion during opening and closing of the sliding door.
  • the flat cable pull-out direction conforms with the protrusion direction of the convex flexural portion.
  • EP 1721802 describes an opening-closing device with a lock for also performing a closing lock by power of an actuator for opening and closing a sliding door. Further, it is prevented that the lock is performed before reaching a full closing position and the lock is unintentionally released at a breaking time of the actuator.
  • Further actuator as an opening-closing driving source of sliding doors able to be reciprocated is described, a planetary gear mechanism for inputting driving force of this actuator thereto, and a lock mechanism able to lock the sliding doors in a full closing position.
  • the power of the actuator is distributed to a pinion of a rack and pinion mechanism through the planetary gear mechanism, and operates the sliding doors.
  • EP0370513 describes a sliding door system for an elevator.
  • each floor is provided with one or more sliding doors which, relative to the elevator shaft, are located on the external side of the landing door opening.
  • the sliding doors on the floor levels are operated by a power means mounted on the elevator car and engaging the respective door when the elevator stops at a floor level.
  • the power means on the elevator car consists of a motor with a pulley or sprocket drive comprising a catch designed to engage a rope connected to the sliding doors, so that the doors are opend and closed by driving the belt or chain round the wheels of the pulley or sprocket drive through a certain distance.
  • Such maintenance usually requires dismantling the doors or dismantling the door cover as well dismantling parts of a driving mechanisms. In addition to significant down-time, this means very high costs as well as potential problems with fixed mechanisms as such must be assembled in a confined space above or below the doors.
  • Modular sliding member power mechanism solves above referenced technical problem by supplying a power operated sliding member mechanism in a module, such module comprising driving engine, preferably electrical motor, driving means connected to said driving engine, connecting means for connection to sliding member, preferably doors, and release mechanism for releasing of said connecting means, all of the above packaged into modular form for easy installment and removal.
  • driving engine preferably electrical motor

  • the modular sliding member power mechanism is further characterized by locking means which can be used for both connecting of said sliding member to closed position (such as, for example in locked doors position) and release of said locking mechanism via release mechanism.
  • Sliding member such as doors will need to be secured in closed position.
  • State of the art locks can be used for this purpose.
  • Such lock can be, for example, key operated. At least one key can therefore be used to engage lock in order to lock the sliding member such as doors.
  • the same key can be used by turning in opposite direction from locking to first unlock said sliding member such as doors, and then by continuing turning to disengage said connecting means from said sliding member via release mechanism which releases locking mechanism connecting said sliding member to said driving means.
  • sliding member can then be operated manually by simply sliding it using drive rail as free sliding member, preferably doors.
  • the driving engine is engaged, driving in turn said driving means with connecting means until such time that connecting means re-engage with sliding doors automatically locking them with locking mechanism.
