Claims22
An elevator cab assembly comprising:
- side walls and a ceiling connected to the side walls, wherein the side walls comprise a plurality of wall panels each having at least one longitudinal edge interlocking with a longitudinal edge of an adjacent wall panel to connect wall panels together without additional fasteners, wherein each interlocking longitudinal edge has a flange with cutaway areas defining a plurality of alternating locking members and slots and wherein the locking members of a wall panel flange are insertable through slots of an adjacent wall panel flange and longitudinally moveable relative thereto to engage the locking members of the two wall panel flanges to connect the wall panels together.
An elevator cab assembly comprising:
- side walls and a ceiling connected to the side walls, wherein the ceiling comprises a plurality of ceiling panels each having at least one longitudinal edge interlocking with a longitudinal edge of an adjacent ceiling panel to connect the ceiling panels together without additional fasteners, wherein each interlocking longitudinal edge has a flange with cutaway areas defining a plurality of alternating locking members and slots and wherein the locking members of a ceiling panel flange are insertable through slots of an adjacent ceiling panel flange and longitudinally moveable relative thereto to engage the locking members of the two ceiling wall panel flanges to connect the ceiling panels together.
A method of assembling an elevator cab comprising the steps of:
- connecting a plurality of side wall panels each having at least one longitudinal edge by interlocking one longitudinal edge with a longitudinal edge of an adjacent wall panel without additional fasteners to form side walls, wherein each interlocking longitudinal edge has a flange with cutaway areas defining a plurality of alternating locking members and slots and wherein the locking members of a wall panel flange are insertable through slots of an adjacent wall panel flange and longitudinally moveable relative thereto to engage the locking members of the two wall panel flanges to connect the wall panels together;
- and connecting a ceiling to the side walls.
