  • Patent number: 9604822
    Abstract: An elevator includes at least one elevator car driving in an elevator shaft driven by an elevator drive. The elevator car has at least one car door and a door sill at the bottom of the car door, which door sill includes at least one groove, in which the car door is guided, in which groove at least one trash hole is located to prevent trash from accumulating in the groove, whereby the elevator car further includes a toe guard which extends downwards from the door sill. The trash hole is connected with a first upper end of an air channel extending downwards from the door sill and includes at least one channel portion extending with a direction component in a horizontal direction and/or having an opening directed sideward, which air channel is connected with the toe guard. The elevator leads to a reduced noise generation in the region of the door sill, particularly in elevator cars traveling with a high speed.
