  "abstract": "An elevator car includes supporting sections, which are arranged on a car frame. Each supporting section has a foot, a first arm and a second arm. The foot is fastened to the car frame, at their free ends the arms converge and form a slit-shaped constriction, into which panel sections of panels that form walls or a ceiling can be clipped. The arms possess spring properties and, at the constriction, can be moved apart against a spring force. The arms hold the panel sections in position in the area of the constriction.",
  "claims": [
    "1. An elevator car, comprising: a car frame; a car floor, a car ceiling and car walls each fastened to the car frame and cooperating to form an interior space of the elevator car; a plurality of panels, the plurality of panels forming at least one of the car wall and the car ceiling; first fasteners on the panels; and second fasteners, the plurality of panels being clippably held in place by the first and second fasteners, the second fasteners being arranged on the car frame each of the panels of the plurality of panels being installable onto the car frame from within the interior space by engagement of the first fasteners with the second fasteners, and each of the panels being non-destructively removable from the car frame from within the interior space without moving any of the car floor, the car ceiling, the car walls and any other one of the plurality of panels relative to the car frame.",
    "2. The elevator car of claim 1, further comprising supporting sections, the supporting sections comprising the second fasteners.",
    "3. The elevator car of claim 2, the first fasteners comprising panel sections, the panel sections being clipped to the supporting sections.",
    "4. The elevator car of claim 3, each of the supporting sections comprising a respective foot and respective two arms, the two arms having spring properties and holding one of the panel sections in position.",
    "5. The elevator car of claim 3, the panel sections comprising respective corners, one or more portions of the panel sections having been cutaway at the respective corners.",
    "6. The elevator car of claim 1, further comprising a piece of car equipment built into one of the plurality of panels.",
    "7. The elevator car of claim 1, the plurality of panels forming a car wall.",
    "8. The elevator car of claim 1, the plurality of panels forming a car ceiling.",
    "9. An elevator installation comprising: an elevator car, the elevator car comprising, a car frame, a car floor, a car ceiling and car walls each fastened to the car frame and cooperating to form an interior space of the elevator car, a plurality of panels, the plurality of panels forming at least one of the car wall and the car ceiling, first fasteners on the panels, and second fasteners, the plurality of panels being clippably held in place by the first and second fasteners, the second fasteners being arranged on the car frame, each of the panels of the plurality of panels being installable onto the car frame from within the interior space by engagement of the first fasteners with the second fasteners, and each of the panels being non-destructively removable from the car frame from within the interior space without moving any of the car floor, the car ceiling, the car walls and any other one of the plurality of panels relative to the car frame.",
    "10. An elevator car construction method, comprising: attaching a first plurality of panels to a car frame from an interior space of the car frame to form a car wall; and attaching a second plurality of panels to the car frame from the interior space of the car frame to form a car ceiling, the first and second plurality of panels being clippably held in place by first fasteners on the panels and second fasteners, the second fasteners being arranged on the car frame, each of the panels being installable onto the car frame from within the interior space by engagement of the first fasteners with the second fasteners, and each of the panels being non-destructively removable from the car frame from within the interior space without moving any of a car floor, the car ceiling, the car wall and any other one of the panels relative to the car frame.",
    "11. The elevator car construction method of claim 10, the attaching of the first plurality of panels and the attaching of the second plurality of panels being performed without a tool."

  "description_excerpt": "The disclosure relates to an elevator car.\n\nFrom patent specification U.S. Pat. No. 1,718,014 an elevator car has become known whose walls form a passenger space or a freight space. The walls are composed of rectangular-shaped panels. At least along both of its long sides, each panel is bent, the panel section that is so bent by approximately 90° being bent along its edge by a further 90°. The bent panel section touches the bent panel section of the adjacent panel, a clamping section that releasably fastens the two adjacent panels at the bent edges being slideable over the bent edges along the long side of the panel. The car wall that is visible to the user of the elevator car therefore comprises a closed surface with only fine joint gaps between the panels. Disadvantageous with this type of panel fastening can be the difficult installation of the clamping sections, since the panels extend over the entire height of the car and, correspondingly, the clamping sections are pushed along the entire height of the car over the bent edges of the bent panel sections, the frictional force, and hence the force for pushing, continuously increasing on account of the clamping effect. Also, when replacing a panel, the clamping-section join can be disadvantageous, because for one panel two clamping sections must be removed and inserted again.\n\nAt least some of the disclosed embodiments comprise car walls and/or a car ceiling with panels for an elevator car which are easily mountable and easily replaceable.",
