Definitions
- the invention relates to a car floor for an elevator car and a method for assembling an elevator car.
- Elevator systems for transporting people and goods contain elevator cars that can be moved up and down in an elevator shaft.
- the elevator cars can be moved by means of a drive unit via suspension means, for example in the form of suspension ropes or suspension belts.
- suspension means for example in the form of suspension ropes or suspension belts.
- no car frames are necessary.
- the car floor is brought into the shaft pit. After that, to complete the elevator car, the car side walls and the ceiling can be installed. It often happens that the bottom of the shaft is not completely level. There is therefore a need to compensate for such unevenness in the floor or to level the cabin floor for other reasons.
- the car floor for an elevator car includes a preferably flat base part for specifying an access area for passengers in the interior of the elevator car. Because mounting feet are arranged on the base part, at least one of the mounting feet and preferably each of the mounting feet being a height-adjustable mounting foot for aligning the base part in a horizontal position, the cabin floor can be leveled easily and efficiently. Mounting feet receptacles for receiving the mounting feet can also be provided on the base part, so that mounting feet can be arranged on the base part. About the mounting feet of the car floor during an assembly phase on a shaft floor of an elevator shaft be supported or parked.
- the local vertical position of the base part can thus be set in the area of the respective mounting foot.
- the height adjustment relates to the distance between the base part and the cabin floor. Depending on the direction in which the setting is made on the respective height-adjustable mounting foot, this distance can be increased or decreased and the desired height can be set.
- the mounting feet can be removed again after the end of the mounting phase.
- the mounting feet can also be arranged permanently on the base part.
- the base part is, for example, a component with a composite structure or sandwich construction, as has become known, for example, from EP 1 004538 A1.
- the base part includes a base plate, a cover plate and an intermediate composite structure core.
- the composite structure core which forms the connection between the base and cover plates, can be built up from a large number of upright, crossing lamellas in the form of a grating, which are fixedly connected to the base and cover plates in a suitable manner.
- the base part can also be constructed in a different way.
- the core could be formed by one or more layers of honeycomb structures.
- the base part can have a rectangular shape in plan view.
- four mounting feet are provided, which are arranged in the corner areas of the base part.
- Mounting foot receptacles can also be provided in the corner areas of the base part.
- the arrangement in the corner area includes an arrangement of the mounting feet in the vicinity or adjacent to the corners of the base part. It is therefore not necessary that the mounting feet directly on the geometric corner are positioned.
- the mounting feet can be positioned inside or outside the vertical projection of the base part.
- the cabin floor can thus be supported on the floor of the shaft during the assembly phase by preferably four height-adjustable assembly feet.
- the mounting feet centrally on the four sides of the rectangle of the base part.
- the respective height-adjustable mounting foot can be configured and preferably manually operable in such a way that the height can be adjusted from the base part.
- Such motor-driven mounting feet could also be operated by remote control.
- the respective height-adjustable mounting foot can be moved up and down in the vertical direction by means of mechanical means, for example by means of a worm gear.
- mechanical means for example by means of a worm gear.
- other mechanical means such as a ratchet mechanism, a carriage guide, a crank device, a latching device, a telescoping rod or a carriage guide can also be considered.
- hydraulic or pneumatic means for adjusting the height of the mounting foot are also conceivable.
- the mounting foot can be height-adjustable via a threaded spindle.
- Such threaded spindles are inexpensive and are characterized by robust and easy handling.
- the height-adjustable mounting foot, which can be operated using the threaded spindle, can be easily set to the desired height.
- the respective height-adjustable mounting foot can have a threaded rod which is accommodated or can be accommodated in an internal thread assigned to the base part and corresponding to the threaded rod in order to form the threaded spindle.
- the assembly foot can thus be designed as a spindle screw.
- the threaded rod preferably extends in the vertical direction during the assembly phase and when it is arranged on the base part.
- the internal thread can form the previously mentioned mounting foot receptacle.
- Spacer elements for positioning the mounting flange outside of a vertical projection of the base part can be fastened or formed on the side of the base part.
- the spacer elements can contain the internal threads in which the threaded rods of the assembly flisse are or can be accommodated.
- the spacer elements are, for example, angle pieces that are attached to vertical side wall sections of the base part
- the base part can have internal threads integrated therein, into which associated threaded rods are received or can be received to form the height-adjustable mounting feet.
- the base part can have internal holes in the corner regions, into which the threaded rods are passed, wherein the holes for forming the threaded spindle can have internal threads at least in sections.
- the aforementioned base plate of the base part can have a hole for each mounting foot, into which the threaded rods are passed or inserted.
- stamp-like support elements are arranged on the lower ends of the respective threaded rods facing the bottom of the shaft to enlarge the support surface to the bottom of the shaft.
- These support elements can be connected to the threaded rods in an articulated manner, for example via ball bearings.
- engaging or actuating means such as tool holders for screwdrivers or wrenches, set screws with separate rotary handles, wing screws or toggle screws can be arranged, which simplifies manual actuation of the threaded spindle to adjust the height of the mounting foot.
- a lock nut is attached to the threaded rod to secure the height adjustment.
- at least one spirit level is attached to the base part to check the horizontal position.
- the spirit level can be attached to the base part at least temporarily or permanently.
- the level can be a circular level or a tube level.
- the spirit level can be attached to the base part by means of an adhesive connection. When using tube levels, it can be advantageous if the
- Tube levels are arranged in a cross shape to each other.
- a further aspect of the invention relates to a method for installing an elevator car in an elevator shaft of an elevator installation.
- the method can include the following steps: (i) introducing a car floor, in particular the car floor described above, into the elevator shaft, the car floor being set down on the shaft floor; (ii) leveling of the cabin floor standing on the floor of the shaft via assembly feet, in that at least one height-adjustable assembly foot arranged on the cabin floor is actuated for height adjustment; and (iii) installation of the cabin side walls and preferably the following

- the height-adjustable mounting feet are arranged outside of the vertical projection of the base part 4.
- FIG. 5 shows a variant in which the height-adjustable mounting feet 5 are arranged within the vertical projection of the base part.
- the height-adjustable mounting feet 5 are designed and can be actuated manually in such a way that the height can be adjusted from the base part 4 . In this way, the imbalance (indicated by the angle of inclination a of the cabin floor relative to the horizontal) can be eliminated.
- the fitter actuates the left-hand, height-adjustable mounting foot designated 5'.
- the respective mounting foot 5, 5' can be moved up and down in the vertical direction for height adjustment by means of mechanical means 10, for example by means of a helical gear.
- the mounting foot 5 can be adjusted in height via a threaded spindle.
- the height-adjustable mounting foot 5 has a threaded rod 11 which is received in an internal thread which is assigned to the base part 4 and corresponds to the threaded rod. Thanks to the threaded rod 11 running in the vertical direction, the cabin floor
- the spacer elements 14 contain the internal threads in which threaded rods 11 of the mounting feet 5 are accommodated. At the lower ends of the threaded rods 11 facing the bottom of the shaft, as shown in Fig.
- stamp-like support elements 12 can be arranged to enlarge the contact surface to the bottom 7 of the shaft.
- the upper threaded rod end of one of the threaded rods 11 is detected by means of a tool (not shown here), for example, and rotated either clockwise or counterclockwise as desired to adjust the height.
