Definitions

  • the present invention relates to a suspension and guiding arrangement for centrally opening panel doors for elevators.
  • Elevators typically have a door both in the shaft doorway, which is called a landing door, to prevent falling into the shaft, as well as in the elevator car doorway to protect the passengers during elevator movement.
  • the general structure of both doors is similar, i.e. they usually have the same opening configuration and the number of door panels. However, they can have differences for example in their locking mechanisms, fire-resistance and soundproofing properties.
  • the door panels typically hang from a suspension and guiding arrangement comprising at least one guide rail attached to the door frame and, for each door panel, a panel guide and two or more wheels called guide rollers.
  • the panel guide can vary in shape and be either continuous piece with the door panel, or be constructed from one or more separate pieces attached to the door panel.
  • the guide rollers are attached either to the panel guide or to the guide rail and allow the movement of the door panel along the guide rail by rotating (as disclosed for example in the patent CH 365844 ).
  • the typical arrangement of the guide rollers is that they are situated above the door panel near its each vertical edge and mounted on the panel guide. The distance between their rotational centers, called wheelbase, is slightly shorter than the width of the door panel.
  • the guide rollers are accompanied by so-called anti-tip rollers that are mounted to the panel and roll, for example, along the underside of the guide rail or along its upper rim to balance the door.
  • each panel has a cross member that contains a guide rail.
  • Each cross member has an extension in the form of an arm, at the end of which there is a rotating roller which seats on the guide rail mounted to the door frame.
  • the guide rail of the cross member moves on the stationary roller carried by the door frame during opening and closing of the door, whereas the rotating roller at the end of each cross member arm moves along the guide rail mounted to the door frame.
  • An object of the present invention is to improve the door guiding properties of a door suspension and guiding arrangement for centrally opening automatic elevator doors. Another object is to improve the reliability and smoothness of the door function for centrally opening automatic elevator doors.
  • centrally opening doors herein is meant doors that slide horizontally sideways, where the moving can be arranged in different ways, such as rollers, wheels or guide shoes moving on guide rails or guide rails moving on rollers, wheels or guide shoes.
  • the centrally opening doors can also move using other mechanisms than the above-mentioned ones.
  • the door suspension and guiding arrangement for centrally opening elevator doors presented here is characterized by comprising two or more door panels supported by a panel suspension and guiding arrangement so, that each door panel has a panel guide comprising at least two guide rollers which rollers allow the respective door panel to move in the direction of a guide rail between a closed and an open position of the door and in that the distance between the two guide rollers is greater than the width of the door panel to which they are attached, the at least two guide rollers are configured to move with the movement of the door panel and the distance between the at least two guide rollers is substantially the same in all positions of the door panel.
  • an elevator comprising an elevator shaft, an elevator car arranged to move within the elevator shaft, an elevator car door and two or more landing doors, characterized in that a door suspension and guiding arrangement according is used in at least one of said doors.
  • the door suspension and guiding arrangement can be utilized in both landing doors and elevator car doors, as the need for improved guiding exists in both.
  • the panel guide is attached to the door panel or is an integral part of the door panel.
  • the door panel is supported by guide rollers.
  • the distance between the two guide rollers is exactly the same in all positions of the door panel.
  • the guide rollers are configured to move within or on top of the guide rail.
  • each door panel has two guide rollers located substantially at opposite ends of the panel guide.
  • At least one anti-tip roller is included in the panel guide.
  • each panel guide has its own guide rail.
  • At least some of the door panels opening to the left use a common guide rail and at least some of the door panels opening to the right use a another common guide rail.
  • each door panel is supported by two guide rails so, that all the guide rollers closest to the vertical center line of doorway when the door is open use a common guide rail and the other guide rollers use a second common guide rail.
  • the door suspension and guiding arrangement is used in a landing door.
  • the door suspension and guiding arrangement is used in an elevator car door.
  • Fig. 1 presents a door suspension and guiding arrangement 3 of an elevator door in which the door comprises two door panels 1, 2 and each of them moves along its own guide rail 8, 9.
  • the guide rails 8, 9 are mounted either to the door frame or to the elevator car.
  • the guide rails 8, 9 are drawn to be vertically stacked. They could alternatively be on the same vertical level, one behind the other.
  • Each door panel has two guide rollers 4, 5; 6, 7 attached to a panel guide 16, 17.
  • the guide roller 4, 5, 6, 7 is a wheel, ball or other round element known in the field for such a structure.
  • Each panel guide 16, 17 has the form of an arm attached vertically above the door panel 1, 2.
  • Fig. 1 presents only a generalized overview of its structure.
  • the panel guide 16, 17 could be extended from its other end.
  • each panel guide 16, 17 is attached to the respective door panel 1, 2 over the entire width of the door panel 1, 2.
  • the panel guide 16, 17 could be attached to the respective door panel 1, 2 over a shorter distance (than the whole width of the door panel) or could be attached at certain points (e.g. through welding or other fastening).
  • Door panel 1 opens to the left along guide rail 9 with the assistance of guide rollers 6 and 7.
  • Door panel 2 opens to the right along guide rail 8 with the assistance of guide rollers 4 and 5.
  • the wheelbase of the guide rollers (i.e. the distance between the rotational centers of the guide rollers) of each door panel is approximately three times the width of the door panel, but also shorter and longer wheelbases can be used. In Fig.
  • the guide rails 8 and 9 are drawn to be continuous, but when the wheelbase of the guide rollers 4 and 5, and 6 and 7, respectively, exceeds the distance moved by the door panel during opening and closing of the door, the guide rails 8 and 9 can be made discontinuous by omitting the parts which are not used by any of the guide rollers 4, 5, 6 and 7. In the embodiment of Fig. 1 , this would cover almost the whole width of the doorway (indicated by the grey bar at the top of Fig. 1 ). This alternative would reduce the weight of the door suspension and guiding arrangement and further stabilize the construction. In this view, door panel 1 is partly behind door panel 2 (indicated by the dashed outline). Any conventional actuator can be used to move the door panels 1, 2 and is not included in the drawing.
  • the door arrangement can contain additional safety, automation or other devices which are omitted from this drawing.
  • the bottom part of the door frame or elevator car comprises a guiding groove 12.
  • At the bottom of the door panel one or more guide shoes, sliding guides or roller shoes 13 is attached to each door panel or to at least one door panel and is allowed to move within the guiding groove. This improves the stability of the door. Any conventional method can be used for their design and they are only included in the drawing for completeness of the door structure.
  • the hatched area in Fig. 1 drawn below the door panels indicates the width of the door when it is open and is not part of the construction but included in the drawing for clarity.
  • Fig. 2 presents the door suspension and guiding arrangement of Fig. 1 when the door is open.
  • the door panel 1 has moved to the left along guide rail 9 with the assistance of guide rollers 6 and 7 whereas door panel 2 has moved to the right along guide rail 8 with the assistance of guide rollers 4 and 5. Because all the guide rollers 4, 5, 6, 7 are attached to the door panels through panel guides 16, 17, the wheelbase of guide rollers 4 and 5, 6 and 7, respectively, has remained unchanged when the doors are open in comparison to when the doors are closed (as illustrated in Fig. 1 ).
  • Figures 3 and 4 present the door suspension and guiding arrangement 3 of Figures 1 and 2 along three longitudinal transverse lines, A-A', B-B' and C-C' (the dashed lines indicated in Figs. 1 and 2 ).
  • the door is closed and in Fig. 4 the door is open. Only the top and bottom parts of the door arrangement are shown.
  • the guide rails 8, 9 are constructed from a profiled metal (e.g. steel) piece and the panel guides 16 and 17 are made of separate metal (e.g. steel) pieces attached to the door panel 1, 2.
  • the guide rails 8, 9 are constructed from a profiled metal (e.g. steel) piece and the panel guides 16 and 17 are made of separate metal (e.g. steel) pieces attached to the door panel 1, 2.
  • the drawings depict only one possibility.
  • the guide rails 8, 9 do not need to be made of a single metal sheet, the profiles of the different guide rails 8, 9 do not need to be identical and different types of guide roller 4, 5, 6, 7 designs can be used.
  • the panel guides 16, 17 are staggered, so that they have room to move on the adjacent guide rails 8 and 9 between the open and closed position of the door.
  • the shaft 15 connecting guide roller 4 to door panel 2 is longer than that connecting guide roller 6 to door panel 1.
  • Guide roller 5 (although not illustrated in Fig. 3 ) can be arranged in the same manner as guide roller 4.
  • Guide roller 7 (although not illustrated in Fig. 3 ) can be arranged in the same manner as guide roller 6.
  • the guiding groove 12 and guide shoes, sliding guides or roller shoes 13 described in Fig. 1 are also shown.
  • the guide shoe, sliding guide or roller shoe 13 is drawn here as a cross section of a guide shoe, it can have any alternative construction, such as a wheel, or a ball or a slider, known in the field for such a structure. It can take support either from the side walls or from the bottom of the guiding groove 12 and it can be an integral part of the door panel 1, 2 or be attached to it.
  • Fig. 5a presents one half of a door suspension and guiding arrangement 3 according to another embodiment.
  • the door panels 1a, 1b, 1c are aligned next to each other to close the doorway together with the corresponding door panels from the opposite side (not shown in the drawing).
  • the door has six door panels in which all three door panels 1a, 1b, 1c opening to the left share one guide rail 8.
  • the guide rail 8, as well as the corresponding guide rail on the other side of the door suspension and guiding arrangement (not shown), is mounted either to the door frame or to the elevator car.
  • the vertical dashed line depicts the vertical center line of the doorway and the hatched area below the door panels 1a, 1b, 1c indicates the half of the door width when the door is open.
  • Each door panel 1a, 1b or 1c moves along guide rail 8 with the assistance of guide rollers 6a and 7a, 6b and 7b or 6c and 7c, respectively.
  • the wheelbase of the guide rollers 6a, 6b, 6c of each door panel 1a, 1b, 1c is approximately 2.5 times to 3 times as long as the width of the door panel 1a, 1b, 1c so, that the wheelbase is the longest for door panel 1c and shortest for door panel 1a.
  • each panel guide 16a, 16b, 16c has two anti-tip rollers 10a and 11a, 10b and 11b or 10c and 11c, respectively, to stabilize the door panel 1a, 1b, 1c movement.
  • the anti-tip rollers are mounted to the panel guide 16a, 16b, 16c and roll along the underside of the guide rail 8. Depending on the structure of the guide rail 8, they could also roll along its upper rim to balance the door panel 1a, 1b, 1c.
  • only one anti-tip roller per door panel may be used as an alternative.
  • the door panels according to this embodiment may be implemented without any anti-tip rollers.
  • the door panels 1a, 1b, 1c are staggered appropriately to allow the free movement of the door panels 1a, 1b, 1c and guide rollers 6a, 6b, 6c.
  • guide rollers 6a, 6b, 6c, 7a, 7b, 7c (as well as the shafts of the optional anti-tip rollers 10a, 10b, 10c, 11a, 11b, 11c) could be of different lengths and/or the panel guides 16a, 16b, 16c could be curved or nested.
  • the panel guides 16a, 16b, 16c do not necessarily need to be of different height, this alternative was chosen in the drawing for clarity. Any conventional actuator can be used to move the door panels 1a, 1b, 1c and is not included in the drawing.
  • the door arrangement can contain additional safety or automation devices which are omitted from this drawing.
  • the movement of the door panels 1a, 1b, 1c during opening and closing of the door can be synchronized through any conventional method.
  • the bottom part of the door frame or elevator car is drawn to contain a guiding groove 12.
  • One or more guide shoes, sliding guides or roller shoes 13 is attached to each door panel or to at least one door panel and is allowed to move within the guiding groove 12 as described for Figs 1 , 3 and 4 .
  • Fig. 5b presents the door suspension and guiding arrangement of Fig. 5a when the door is open.
  • the door panels 1a, 1b, 1c have moved to the left away from the doorway behind one another so, that door panel 1c is the foremost one in this view.
  • the extended arms of the panel guides 16a, 16b, 16c to which the guide rollers 7a, 7b, 7c and the optional anti-tip rollers 11a, 11b, 11c are attached are scaled so, that in this position they are tightly aligned to allow the maximum wheelbase for the guide rollers 6a, 6b, 6c and 7a, 7b, 7c.
  • shorter constructions are also possible.
  • Fig. 6a presents an example of another door suspension and guiding arrangement 3 in which there are two door panels 1, 2 and the door is closed (i.e. both door panels 1, 2 are closed).
  • the vertical dashed line depicts the vertical center line of the doorway and the hatched area below the door panels 1, 2 indicates the door width when the door is open.
  • the guide rails 8, 9 are mounted either to the door frame or to the elevator car.
  • the panel guides are of different shape so that panel guide 16 has an elongated opening 14 through which the shaft 15 of guide roller 4 extends to guide rail 8.
  • the opening 14 allows the panel guides to move in opposite directions along the same guide rail 8.
  • the wheelbase of the guide rollers of each door panel is approximately two times as long as the width of the door panel. Because all the guide rollers 4, 5, 6, 7 are attached to the door panels 1, 2, through panel guides 16, 17, the wheelbase of guide rollers 4 and 5, 6 and 7, respectively, remains the same when the door panels are in the open position and in the closed position. Any conventional actuator can be used to move the door panels 1, 2 and is not included in the drawing.
