Definitions

  • the invention relates to an elevator door guide system according to the preamble of claim 1.
  • the international patent application WO 2005/09884 A1 proposes an elevator door guide system for a telescopic elevator door, in which each door panel hangs on a carriage, which is hung with its overhead guide rollers in a guide rail. All guide rollers are the same size. At least the carriage of the faster-moving panel has additional, counter-rollers at the bottom, which prevent unintentional unhooking of the carriage and especially his commuting due to strong acceleration or deceleration.
  • the two guide rails are connected together by an aligned row of centrally-penetrating screws and with a separate bracket for wall mounting the elevator door guide system. So, as the screw has been specifically implemented here, the screws are exposed to a significant bending moment. They are therefore, as well as the guide rails themselves, correspondingly massive dimensions. This means that in particular in the vertical direction in addition to the space required by the guide and counter rollers anyway, further space is required, which is consumed exclusively by the guide rails and their screwing.
  • the British patent UK 738 846 proposes a comparable elevator door guidance system, which differs from the aforementioned patent application WO 2005/09884 Al differs essentially only in that the guide rollers of the slower running carriage have a smaller diameter to make room for the rope drive, with which the faster carriage drives the slower.
  • the Chinese utility model application CN 201834637 U proposes a solution that, in principle, corresponds to the solution that describes the two previously mentioned documents.
  • an attempt is being made to make the construction less expensive by omitting the solid guide rails. Instead, a tubular, circumferentially self-contained guide rail is used. This actually saves material.
  • the production of the tubular, quite complicated shaped guide rail increases the production cost.
  • the design proposed by the Chinese utility model does not take into account how much space 20 is consumed, especially not in the vertical direction.
  • the elevator door guide system consists of at least two guide rails arranged side by side with respect to the opening and closing direction.
  • the guide rails are therefore at least substantially at the same height.
  • the guide rails lie completely at the same height and thus aligned in the horizontal direction.
  • the guide rails are connected to each other by connecting elements, which are preferably formed by the connection element system to be explained later, which includes special connecting bolts and end screws.
  • hanger plate On the guide rails carriages are guided. These typically consist of a single or multi-part sheet metal plate and are therefore also called hanger plate. Of course, door panels with integrated hanger plate are conceivable.
  • an inner carriage is guided on smaller rollers.
  • Under rollers are understood to mean those roles in which the carriage is suspended. Smaller these rollers compared to the diameter of the larger rollers, with the help of an outside carriage is performed, where it comes for the terms "smaller” and “larger” as a rule to the maximum diameter at the outermost circumference of the respective rollers.
  • As internal a carriage is called, which is arranged between two guide rails.
  • the invention is characterized in that the space above or below the smaller rollers accommodates at least one connecting element, by means of which a plurality of guide rails are connected to one another and if necessary also the same with the shaft wall or a carrier element to be fastened to the shaft wall, in which it is preferably a carrier sheet.
  • this connecting element is arranged so that the smaller rollers roll in the course of the opening or closing movement under said connecting element, while the larger rollers of the other carriage said connecting element happen laterally.
  • the guide rails can better brace against each other to a bending load as a unit-defying package, so that not least a higher stability against force effects is achieved, as they arise when the door panels are loaded in a horizontal direction, such as by people who lean on the door panel.
  • This makes it easier to use the guide rails as sheet metal parts instead of massive profiles.
  • the smaller diameter rollers are those on which the slower moving carriage is suspended.
  • the slower moving carriage only covers half the distance in each opening and closing operation, which is why its rollers are naturally subject to less wear than that of the faster running carriage.
  • This embodiment of the invention is based on the recognition that larger rollers are less susceptible to wear, but it makes no sense to run the less-loaded wheels of the slower running and within the product life only a smaller way traversing carriage as large as that of the faster running carriage.
  • roller diameter possible to run the rollers of the faster running carriage so large that they can be made of plastic, without risking excessive wear.
  • the smaller rollers are then also made of plastic or advantageously made of metal.
  • the guide rails are connected at their seen in the direction of the left and right ends by at least two connecting elements with each other, which are aligned along an imaginary first line with each other, which extends transversely, preferably perpendicular to the direction.
  • At least one additional connecting element for connecting the two or more guide rails is provided at the same time along an imaginary second line which extends at least substantially parallel to the running direction, each with at least one connecting element connecting the right and left ends of the guide rails flees.
  • the guide rails are not pressed against each other only in a single plane by the connecting elements. Rather, the connecting elements are spatially distributed in such an arrangement such that the guide rails are connected by the connecting elements at both horizontally and vertically spaced points by the connecting elements and preferably compressed. This results in an overall stiffer unit.
  • the bearing axis of the larger rollers seen in the vertical direction is arranged above the bearing axis of the smaller rollers. In this way, the space that can be optimally used on the side of the large rollers of the fasteners in Claimed.
  • the internal, d. H. the on the side facing away from the elevator shaft carriage with the smaller rollers one who runs in the space between two adjacent guide rails. This applies both when the elevator door guide system according to the invention is used to realize a landing door, as well as when it is used to realize a car door.
  • the elevator door guide system according to the invention can also consist of three or more adjacent guide rails. It is then preferably such that the innermost carriage seen from the shaft side is guided on rollers with a larger diameter, while all other carriages have rollers whose diameter is smaller than that of the large rollers. In this case, run several moving in parallel planes carriages with small rollers in the various spaces between guide rails.
  • a multi-part connector system is used for the elevator door guide system. It comprises at least one connecting bolt, which has a main portion, which is provided on its one end face with a threaded bore. From the connecting bolt is on the other end face from a threaded pin whose outer diameter is smaller than the outer diameter of the main portion of the connecting bolt.
  • the threaded bore and the threaded pin are preferably matched to one another such that a plurality of identical connecting bolts can be screwed into one another in such a way that they have a common longitudinal axis.
  • the system may include connecting bolts of different overall length, whereby the distance between the individual guide rails in each case from each other comply, can be varied.
  • To the connecting element system preferably also include additional end screws having a flat head whose thickness in the direction of the screw longitudinal axis is smaller than 1.5 times the thickness of the guide rail at the screwing, also measured in the direction of the screw longitudinal axis.
  • Such end screws are particularly useful when using guide rails made of sheet metal. They take away little space in the horizontal direction without the need to make a countersink that would be difficult to produce in a sheet-metal profile for countersinking the screw head.
  • a first guide rail is screwed to the corresponding carrier unit with the aid of the described connecting bolts.
  • the guide rail is thereby clamped between the carrier unit and the connecting bolt at the point at which the threaded pin of the connecting bolt merges into its main section, which has a larger diameter.
  • the main section is preferably provided with a shoulder surface for a screwing tool.
  • a guide rail for an elevator door guide system is claimed, which is designed as a sheet metal bent part and has a downwardly open U-section section, which in turn has a tread for includes the guide rollers of a door panel.
  • the guide rail according to the invention also has a secondary section, which forms a running surface for the counter-rollers of the aforementioned door panel.
  • the secondary section and the U-profile section are integrally connected to each other, ie they represent a unitary sheet metal bent part, so they are not caused by screwing or welding two initially separate from each other usually produced by bending or rolling items.
  • This guide rail is characterized by the fact that at least one leg of the UProfil section directly adjoining the tread of the roller that has passed the roller has an acute angle ⁇ with the secondary section includes. It is even preferable that the entire U-profile section, which in cross-section consists of a circular section functioning as a running surface and two legs, preferably completely rectilinear, adjoining it on both sides, is inclined towards the side of the secondary section. In this way, the sub-section and the U-profile section do not come to lie completely next to each other, but the U-profile section is at least partially, preferably more than 20% of its extension, in the vertical direction over said side section, although the profile of the guide rail in cross-section is not closed in itself, but open to the side.
