Definitions

  • the present disclosure generally relates to elevator systems with a shaft, at least one car being moveable in the shaft by means of a drive and at least one landing stop for the car. More particularly, the present invention is directed to a landing door of such an elevator system having a side jamb, which forms a housing for a control unit.
  • Elevators for vertically and/or horizontally transporting people and goods are an integral part of modern residential and commercial buildings.
  • a typical elevator system includes one or more elevator cars moved by a hoist system such as an elevator drive, e.g. including a driven sheave assemblies over which one or more tension members are driven or a linear drive system.
  • Elevators usually require a lot of space in a building for the elevator shaft but also for machinery and electronics such as a control unit cabinet. These elements need to be placed in the building in a manner, that they are not consuming too much space, that they are not disturbing, e.g. in regards of interior design, and that they are accessible, e.g. for maintenance. Such placement further requires extensive planning effort. It is therefore known from the state of the art, to integrate the control unit into a side jamb of a landing door of the elevator system, so that no further cabinet needs to be placed in the building. This however requires the control unit to be very small and/or the side jamb to be rather heavy to accommodate the control unit, so that the side jamb is of bulky appearance and requires a large wall break.
  • a landing door with a side jamb accommodating a control unit is for example disclosed in CN 201793289 U .
  • This control unit has a cabinet, which can be slide in and out of the side jamb.
  • the side jamb accommodating the control unit cabinet is rather heavy, in particular as the side jamb accommodates the components of the control unit and the components of the slide mechanism.
  • an elevator system with a shaft, at least one car being moveable in the shaft by means of a drive and at least one landing stop for the car, wherein a landing door is located at the at least one landing stop in a wall of the shaft, wherein the landing door separates the shaft from a landing area, wherein the landing door has at least one door leaf and at least one side jamb, wherein the side jamb forms a housing for stationary installation of a control unit for controlling operation of the elevator system, wherein the housing has at least one pivotable hatch for accessing the control unit, wherein the hatch is accessible from the landing area and wherein the hatch is detachable from the housing.
  • a shaft of the elevator system may extend in vertical and/or in horizontal direction.
  • the shaft extends only vertical or only horizontal.
  • the elevator system has at least one section of the shaft in which the shaft extends vertical and at least one section in which the shaft extends horizontal, wherein the car can pass from the vertically extending section into the horizontally extending section.
  • a drive is, in particular, formed by a sheave assembly driven by a drive device, wherein tension members bear against the sheave with sufficient static friction to apply a drive torque to the tension members.
  • the tension member is connected to the car and preferably to a counterweight, which is raised, when the car is lowered and vice versa or the tension member is connected to at least one fix point in the shaft and passed through the car via underslung or overslung and the counterweight.
  • the drive device is, for example, an electric machine, a pneumatic motor or a hydraulic motor and acts directly or via a gearbox on the sheave.
  • a landing stop is defined by an opening in the drive shaft, e.g. at a certain floor of a building, wherein the opening is formed by a landing door, respectively wherein the door convers the opening.
  • the car preferably has a car door, which aligns with the landing door at the landing stop and is opened in a synchronized manner with the landing door.
  • the car door has a drive mechanism for the opening of the door and has a mechanical or optical coupling mechanism, that couples the car door with the landing door at the landing stop and opens/closes both, the car door and the landing door, synchronously.
  • the landing door may be a sliding door, a pivotable door or a foldable door, wherein it may have one or more door leaves.
  • the door leaf or door leaves open to one side of the landing door. It is also possible that the landing door has more two or more door leaves, which open to the same side, e.g. in a telescopic manner, or to different sides of the landing door.
  • the landing door is located next to at least one side jamb, preferably two side jambs, and preferably a header, wherein the jambs are designed to form a connection between the landing door and a surrounding wall, and cover mechanic parts of the landing door, e.g. the drive mechanisms or guide rails.
  • the jambs further accommodate control elements, e.g. for calling a car and/or identifying a user, and/or information elements like a display or a light element. Neither said control elements nor said display elements are considered to be part of a control unit, although they may interact with the control unit, in particular receive commands from the control unit or sent commands to the control unit.
  • the control unit for controlling operation of the elevator system comprises at least one processor for processing commands from users and/or a state of the elevator system and for controlling the drive and, if feasible, a break device of the elevator system according to the processed commands and/or the state of the elevator system. Therefore the controlling device has a number of electronic components such as circuit boards, processors, microcontrollers, switches and the same. It is a basic design requirement, that these components are accessible for maintenance and in particular for replacement. The side jamb is therefore required to allow enough room for these operations. Maintenance in particular includes visual checking of the components, connecting of cables or application of measuring tools to the components, and/or replacement of components. As the control unit is installed stationary, the components are in a fixed position inside the side jamb and cannot be moved from this position, in particular not be slide out of the housing.
  • the elevator system includes the teaching, that the hatch is detachable from the housing. It is to be understood, that the hatch can be detached with ease, e.g. by a hook mechanism, a hinge mechanism or a clamp mechanism and most preferred without any need for using a tool, that is the hinge is detachable in a tool-free manner. Moreover, the hatch is preferably detachable from the landing area, e.g. from the same position as the hatch can be accessed. It is thereby made possible, that the pivot mechanism of the hatch allows for an opening sufficient for access to the control unit but not for (re)placement of the components of the control unit, respectively the hatch is of a design, which extends into the opening of the housing in the opened state.
  • the housing can be designed smaller/less heavy than known housings.
  • Such a housing requires less space for hatch mounts and/or for pivoting the hatch(es),
  • the side jamb can be designed smaller, respectively provides more room for the control unit, respectively components of the control unit, at the same size.
  • the housing has exactly one pivotable hatch.
  • the side jamb By providing only/exactly one hatch for accessing the control unit at the housing, the side jamb must provide the space accompanying a hatch, e.g. space for mounts and space for pivoting the hatch, only once and is therefore smaller over a side jamb which provides two hatches, e.g. one hatch accessible from the landing area and one hatch accessible from the shaft. Further, with only one hatch, more interior wall space is available for the mounting of components of the control unit.
  • all components of the control unit are accessible from the one hatch, so that the entire control unit is accessible from one single position.
  • the housing may also accommodate components of the control unit in a part of the housing, where the hatch does not extend to, wherein these components do not require maintenance.
  • the hatch is pivotable by 85° or less, 80° or less, 75° or less, 70° or less, 65° or less, 60° or less, 55° or less, 50° or less, 45° or less, 40° or less, 35° or less, or even 30° or less.
  • the pivoting mechanism may therefore be of a smaller/less heavy design.
  • control unit is installed stationary in the housing.
  • the elevator system also comprises the control unit being installed in the housing.
  • At least one component of the control unit is fastened to a back side of the housing vis-á-vis the hatch, whereby an overall comfortable access to the component is provided.
  • the housing has only one hatch, all other sides, in particular a back side, a left side and a right side, viewed from the hatch, are available for fastening of components of the control unit.
  • the hatch comprises means for aligning the hatch with the housing, e.g. an adjustable hook mechanism, hinge mechanism or clamp mechanism, wherein adjustment means and the means for detaching the hatch are independent of each other in their function.
  • the hatch has two locks each locking the hatch against an element of the housing, wherein the locks are distributed over the height of the hatch.
  • the hatch can extend along a substantial part of the height of the side jamb and it is still enabled, to securely lock the hatch.
  • the hatch could be bend open in an act of vandalism or sabotage and the control unit could be accessed by unauthorized persons and would possibly be damaged. Therefore, two locks enable a better extension of the hatch, so that the hatch allows for comfortable access to all components of the control unit, respectively allow the space in the housing along the entire height of the hatch to be utilized by the control unit or parts of the control unit.
  • the two locks are nonvariable parts and can be operated by the same key.
  • the side jamb forming the housing has an emergency release for the at least one door leaf, wherein the emergency release is accessible from the landing area.
  • the emergency release can thereby interact with the control unit, so that beside a mechanical release of the landing door, the emergency release can influence the /interact with control unit, e.g. an actuation of the emergency release is registered by the control unit without extensive hardware requirements like lines and the same.
  • the at least one door leaf is slidable to a side of the landing door opposite the side jamb forming the housing.
  • On the side of the side jamb forming the housing there is then no need to provide space for the door leaves to pull in and the entire space of the side jamb can be utilized for the control unit, so that a comfortable accessible arrangement of the control unit components is favored.
  • more than one slidable door leaf preferably all door leaves are slidable to the side of the landing door opposite the side jamb forming the housing.
  • the landing door has two side jambs on both sides of the at least one door leaf, wherein each side jamb forms a housing for a part of the control unit. It is therefore provided more space for accommodation of components of the control unit.
  • This embodiment might go along with a landing door having two door leaves, which each slide to one side of the landing door. Each side jamb then provides space for the respective door leave to be pulled in and reduced space for accommodating components of the control unit, but still enough space to accommodate the entire control unit in one landing door.
  • both housings each have exactly one pivotable hatch for accessing the part of the control unit, wherein the hatch is accessible from the landing area and wherein the hatch is detachable from the housing.
  • a stationary element of the housing or of each housing is connected to an earthing.
  • the stationary element is not the hatch or a part of the hatch, which is detachable, so that during detachment of the hatch, the housing is still in connection with the earthing.
  • the shaft is vertical and the elevator system has at least two landing stops, wherein the side jamb/s forming the housing/s is/are located at a top landing stop.
  • the top landing stop is the landing area, where most maintenance work for the elevator system is executed.
  • the drive is located in a head space of the shaft.
  • the drive is accessed from the top landing stop for maintenance.
  • the control unit is also located at the top landing stop, most components that require maintenance are located close to each other and maintenance effort is reduced accordingly.
  • a side jamb for a landing door of a predescribed elevator system wherein the side jamb forms a housing for at least a part of a control unit for controlling operation of the elevator system, wherein the housing has exactly one pivotable hatch for accessing the control unit, wherein the hatch is accessible from the landing area and wherein the hatch is detachable from the housing.
  • the predescribed advantages of the elevator system are effected accordingly for the side jamb.
  • the object is even further solved by a landing door for a predescribed elevator system having at least one predescribed side jamb.
  • the predescribed advantages of the elevator system and/or the side jamb are effected accordingly for the landing door.
  • an elevator system 1 has a vertical shaft 2 defined by shaft walls 2.1, 2.2 and a car 3 being moveable in the shaft 2 by a tension member 4, which is driven by a drive not pictured in the figures.
  • the car 3 is at a landing stop 5 of the elevator system 1, which is e.g. a floor level of a building.
  • the shaft wall 2.2 has a wall break, in which a landing door 6 is located.
  • the landing door 6, of which figure 1b shows a front view has a first side jamb 7.1, a second side jamb 7.2, a header 7.3 and a door sill 7.4.
  • the landing door 6 further has two door leaves 8.1, 8.2 which are slidable, e.g. by a drive mechanism in the header 7.3 and/or guide rails in the header 7.3 and the door sill 7.4 not pictured.
  • a control element 9 is located, e.g. for calling a car 3 from the landing area 5.
  • the control element 9 can e.g. be formed by a button, a card reader or a touch sensitive display and may further include an information element like a light element.
  • a car door not pictured aligns with the landing door 6 and a drive mechanism of the car door synchronously opens/closes the car door and the landing door 6, wherein the door leaves 8.1, 8.2 slide to the side of the second side jamb 7.2.
  • the first side jamb 7.1 forms a housing 10 for a control unit 15 as will be described with reference to the figures 2a, 2b, 2c and 2d .
  • the first side jamb 7.1 is formed hollow to provide space for components 15.1, 15.2, 15.3 of a control unit 15, e.g. circuit boards, processors, microcontrollers, switches and the same.
  • the first side jamb 7.1 itself forms the housing 10 integrally and directly within the hollow space for stationary placement of the components 15.1, 15.2, 15.3 of the control unit 15. No further plates, sheets or separate housing elements are provided above mounting means for the components 15.1, 15.2, 15.3 of the control unit 15 inside the hollow space.
