Definitions

  • the present invention relates to a sliding door system for an elevator.
  • Elevator doors can be roughly divided into turning doors and sliding doors on the one hand and car doors and landing doors on the other hand.
  • each floor level 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. That means in other words that the elevator's sliding doors on the floor levels are placed like turning doors of known construction, not inside the elevator shaft like conventional sliding doors.
  • This arrangement offers several advantages: - The elevator doors can be provided with the same safety equipment as conventional sliding doors, e.g.
  • the doors are easier to handle e.g. for handicapped per­sons or children.
  • the arrangement allows mechanical door actuation (which would be unthinkable, in the case of corresponding turning doors), resulting in shorter door operation times and there­fore faster elevator traffic.
  • the arrangement makes it possible to reduce the cross-sec­tional area of the elevator shaft since no part of it is occupied by the door and its mechanisms.
  • the object of the present invention is to provide simple and light actuating means for actuating the respective sliding door located on the external side of the landing door opening.
  • the invention is characterized in that the power means on the elevator car consists of a motor with a pulley or sprocket drive, comprising at least one element designed to engage a rope or equivalent connected to the sliding doors so that the door is opened and closed by driving the belt or chain round the wheels of the pulley or sprocket drive through a certain distance.
  • a preferred embodiment of the sliding door system of the in­vention is characterized in that the elevator car is provid­ed with a gate, a light sliding door or equivalent, which can be pushed aside manually or mechanically when passengers enter or leave the car.
  • the elevator car can be provided with a collapsible gate or preferably with a light sliding door of a segmental construction, which can be so designed that it will take up but very little space and, when opened, is pushed aside into a space which is otherwise useless, e.g. along the external sides of the car walls or between its inner and outer walls.
  • Figures 1a-1c show three elevator doors of known construc­tion, Fig.1a representing an elevator provided with an ordi­nary turning door 1, Fig.1b an elevator with automatic double sliding doors 2,3 both on the elevator car and in the shaft wall, and finally Fig.1c a variation of the previous construction in which all the doors 4,5 move sideways in the same direction.
  • Fig.1a representing an elevator provided with an ordi­nary turning door
  • Fig.1b an elevator with automatic double sliding doors 2,3 both on the elevator car and in the shaft wall
  • Fig.1c a variation of the previous construction in which all the doors 4,5 move sideways in the same direction.
  • The, drawbacks of these constructions have already been described, and special attention should be paid to the placement of the doors in Figs. 1b and 1c when comparing with the constructional alternatives of Figs. 2a-c.
  • Fig. 2a shows a sliding door system with two sliding doors 6 of light con­struction which move in opposite directions.
  • the sliding doors 6 are placed on the external side of the landing door opening 8, and they are operated by a power means mounted on the elevator car 9 (see Fig.4) which engages and actuates the doors when the eleva­tor stops at the landing.
  • the doors should be made flat and smooth, e.g. in accordance with the regulations concerning turning doors.
  • the door opening of the elevator car is provided with the same safety equipment as conventional sliding doors, e.g. with photocells and mechanical or electrical safety edges on the front faces of the doors.
  • Fig. 2b shows a variation of the system in Fig. 2a, with only one door 10 moving sideways (cf. Fig. 1c).
  • Fig. 2c presents another sliding door system resembling the one in Fig. 2a and having two sliding doors movable in opposite directions, each door con­sisting of two or more vertical laminar segments joined together to make the door lighter and more flexible.
  • Figs. 3a-3b shows an embodiment of the sliding door system with doors provided both on the elevator car and on each floor level.
  • the car door is a gate, a light sliding door or equivalent, which is pushed aside manually or mechanically when a passenger enters or leaves the car.
  • the landing door 12 corresponds to the solution in Fig. 2b while the elevator car is provided with a light sliding door 14 or equivalent, which is pushed aside (as indicated by the broken lines) when a passenger enters or leaves the car.
  • This type of gate which may be a collaps­ible gate or, as shown in the present case, a light sliding door consisting of laminar segments, can be so constructed that it will only take up a minimal space and, in the case shown, is pushed aside e.g. along the external side of the car walls.
  • Fig. 3b shows another embodiment of the sliding door system resembling the one in Fig. 3a, in which the landing door opening is provided with two sliding doors 15 movable in opposite directions and the elevator car 17 similarly with two sliding doors 16 movable in opposite directions.
  • the sliding doors 15 at the landings correspond to the solution shown in Fig. 2a, and the light sliding doors 16 are similarly pushed sideways in opposite directions (as indicated by the broken lines) along the external side of the car walls when passengers enter or leave the elevator.
  • Fig. 4 shows a schematic diagram of the door actuating means used in the sliding door system exemplified by Fig. 2b.
  • the basic idea is that the door 10, which is provided with wheels or other sliding elements 24 placed at its lower edge, is driven bY a motor 30 which is mounted on the elevator car 9.
  • the motor drives the upper one of a pair of pulleys of sprockets 18 for a V-belt or chain 19 running around them.
  • the chain is driven anti-clockwise so that a catch 22 on the upper wheel 18 grips a rope 21 connected to the elevator door 10 via a deflecting wheel 20 and other requisites (see Fig. 5).
  • the catch 22 then moves continu­ously downward through a preset distance, it pulls the rope with it through an equal distance, thus causing the elevator door 10 to open by sliding leftwards in Fig. 5.
  • the door opening mechanism is actuated by the motor 30 on the elevator car every time when the car 9 stops at a floor level.
  • a gate or door possibly provided on the elevator car itself can be driven by the same motor 30 as the landing door to open them both simultaneously.
  • the light car door may be of a manually operated design. It is also obvious that the idea of the invention allows some of the sliding doors on the floor levels to be provided with their own power means for mechanical actuation.
  • Fig. 6 shows a view of the floor levels of a building, il strictlylustrating how, by virtue of the invention, different floors can have different door systems for the same elevator car.
  • Reference number 30 identifies an ordinary sliding door, number 31 a dual sliding door with the doorway in the middle, number 32 an ordinary turning door with a door closer, and number 33 a typical basement landing door without an automatic closing mechanism.
  • the same type of sliding doors are used as far as possible, but the invention offers flexibility in the choice of door type and suspension arrangements depending on the space available on the floor level in question, its use and other factors.
