Definitions

  • the invention relates to an elevator car having a multi-part telescopic car apron with a plurality of substantially plate-shaped telescopic elements, which can be converted from a retracted state to an extended state, wherein a plate-shaped telescopic element by a downwardly and rearwardly located plate portion, hereinafter referred bevel, is extended.
  • Car aprons of elevator car baskets are intended to prevent persons from falling into the elevator shaft in the event of an elevator car parked between two floors and to be damaged if the elevator door is opened to release persons. For this reason, an apron is attached to the underside of the car, for example, according to DIN EN 81-1, 8.4: 1998 a skirt minimum height of 750 mm is required. Then, below each car threshold, there must be an apron in the width of the associated landing door, with the vertical part of the skirt being extended downwards by a chamfer whose angle with respect to the horizontal is at least 60 °. The projection of this chamfer on a horizontal plane must not be smaller than 20 mm according to this DIN.
  • This bevel serves as a deflector to avoid foot injuries caused by the passing elevator, if the shaft door is not properly locked, for example, in the ground area and inadvertently protrude into the shaft with his foot waiting for the elevator in front of the shaft door.
  • An Indian WO 2005/121015 A2 illustrated elevator car is provided with a two-part telescopic car apron, in which the first attached to the car telescopic element is extended by a back and down directed bevel.
  • the invention is based on the object, in an effort to reduce the pit height of an elevator system, to reduce the height of the retracted car apron in a lift car while taking into account the applicable for the chamfer of the car apron standard.
  • the elevator car according to the invention is characterized in that the car apron has at least three plate-shaped telescopic elements, of which at least two telescopic elements have a downward and rearward extending chamfer, and that the chamfers are inclined relative to the horizontal at the same angle and lie in the retracted state of the car apron in a common plane.
  • the overall height of the skirt can be shortened in the retracted state, wherein even in the centimeter range lying reductions of Cab apron already lead to significant benefits when retooling or the initial installation of an elevator system, especially in the field pit.
  • FIG. 1 schematically shows a car 2 with attached car apron 1, consisting of four telescopically telescoping plate-shaped telescopic elements 10, 11, 12 and 13, of which the uppermost and outer telescopic element 10 is attached in the region of the threshold 2.1 of the car 2, the substructure 2.2 is indicated schematically.
  • FIG. 2 has the bottom skirt 13 at its lower end a downwardly and rearwardly directed bevel 13.1, followed by a horizontally rearwardly facing bevel 13.2.
  • the skirt 12 also has at its lower end a downwardly and rearwardly directed bevel 12.1.
  • FIG. 4 Different variants are shown in the area of the chamfer of a car apron 1 with a chamfer angle of about 60 °.
  • Complex a shows a four-part telescopic car apron, in which according to the prior art, only a single bevel 13.1 is arranged in the region of the plate-shaped telescopic element 13, which is in the installed state inside and occupies the lowest position in the extended state of the telescopic car apron.
  • Complex b shows a car apron according to the FIGS. 1, 2 and 3 with bevels 12.1 and 13.1 at the lower ends of the telescopic elements 12 and 13th
  • Complex C shows a car apron in which bevels 11.1 and 12.1 are arranged on the telescopic elements 11 and 12, respectively.
  • the telescopic elements 10, 11 and 12 are each provided with chamfers 10.1 or 11.1 or 12.1.
  • the two outer telescopic elements 10 and 11 have at their lower ends the bevels 10.1 and 11.1, respectively.
  • FIG. 4 clearly shows how dividing a single state-of-the-art chamfering complex a into two or three chamfer sections reduces the height of the car apron when retracted, maintaining the required standards whereby the total chamfer is angled relative to the horizontal of at least 60 ° and the projection of this bevel on a horizontal plane has a width of at least 20 mm.
  • the lines A, B, C, and D indicate how the height of a retracted car apron having four panel members can be reduced by dividing the taper into two or more panel members.
