Abstract

The object of the invention is an elevator car intended for transporting people and freight, in an elevator wherein the elevator car is supported resting on suspension members and arranged movably in an elevator hoistway when moved by a hoisting machine. At least the floor and roof of the elevator car are composed of dimensionally precise modular elements fabricated by casting, extruding and/or pressing into their shapes and dimensions.

First claim

The invention claimed is:

1. An elevator car configured to be installed in an elevator, the elevator car comprising:
an elevator car floor including a set of coupled elevator car floor modular elements; and
an elevator car roof including a set of coupled elevator car roof modular elements;
wherein the elevator car is configured to be supported in an elevator hoistway on at least one suspension member;
wherein the elevator car is configured to be moved through the elevator hoistway based on operation of a hoisting machine; and
wherein at least one modular element of the set of coupled elevator car floor modular elements or the set of coupled elevator car roof modular elements is configured to be directly fixed to the at least one suspension member to directly support the elevator car in the elevator hoistway, such that the elevator car is supported, by the at least one suspension member, directly through the at least one modular element of the set of coupled elevator car floor modular elements or the set of coupled elevator car roof modular elements.

2. The elevator car according to claim 1 , wherein,
the at least one modular element is configured to couple with a traction member, and the traction member is configured to move the elevator car through the elevator hoistway.

3. The elevator car according to claim 1 , wherein,
each set of the set of coupled elevator car floor modular elements and the set of coupled elevator car roof modular elements includes a plurality of adjacent modular elements configured to interlock together.

4. The elevator car according to claim 1 , wherein,
the set of coupled elevator car floor modular elements include two corner elements, two intermediate elements and one center element, and
the set of coupled elevator car floor modular elements are configured to be fixed together such that
each corner element is fixed to a separate adjacent intermediate element of the two intermediate elements,
the center element is fixed between the two intermediate elements, and
adjacently fixed modular elements at least partially overlap each other.

5. The elevator car according to claim 1 , wherein,
the set of coupled elevator car roof modular elements include two corner elements, two intermediate elements and one center element, and
the set of coupled elevator car roof modular elements are configured to be fixed together such that
each corner element is fixed to a separate adjacent intermediate element of the two intermediate elements,
the center element is fixed between the two intermediate elements, and
adjacently fixed modular elements at least partially overlap each other.

6. The elevator car according to claim 1 , wherein,
each given set of modular elements, of the set of coupled elevator car floor modular elements and the set of coupled elevator car roof modular elements, includes two corner elements, a center element, and at least two intermediate elements, the intermediate elements in the given set of modular elements configured to be coupled between separate corner elements of the given set of modular elements and the center element of the given set of modular elements; and
the elevator car is configured to be adjusted in width, based on adjustment of at least one of a quantity and a width of the center element and intermediate elements in each set of modular elements.

7. The elevator car according to claim 1 , wherein the set of coupled elevator car floor modular elements and the set of coupled elevator car roof modular elements include at least one of a plastic compound and a plastic composite compound.

8. The elevator car according to claim 1 , further comprising:
a plurality of fabricated wall panels, wherein the plurality of fabricated wall panels are fabricated into their respective shapes from at least one of a plastic compound and a plastic composite compound based on pressing.

9. The elevator car according to claim 8 , wherein,
each given wall panel includes a top edge and a bottom edge;
each of the top edge and the bottom edge includes a batten-shaped fixing edge, the batten-shaped fixing edge being thinner than a thickness of the given wall panel;
each of the elevator car floor and the elevator car roof includes separate, respective corner elements;
each corner element includes a slot corresponding to a batten-shaped fixing edge of at least one wall panel of the plurality of fabricated wall panels; and
each batten-shaped fixing edge of each wall panel is configured to be fixed into a corresponding slot of at least one of the elevator car floor and the elevator car roof.

10. The elevator car according to claim 8 , wherein each given wall panel includes sound-damping elements protruding from the given wall panel, and the sound-damping elements are pressed onto the given wall panel in conjunction with fabrication of the given wall panel.

11. The elevator car according to claim 1 , wherein,
the at least one modular element is configured to couple with at least one of a fixing device or a diverting pulley of the at least one suspension member and a moving device of the elevator car.

12. The elevator car according to claim 1 , wherein at least one modular element of the elevator car roof and at least one modular element of the elevator car floor includes at least one fixing point configured to couple with a car sling to support-the elevator car in the elevator hoistway.

13. An elevator car configured to be installed in an elevator, the elevator car comprising:
an elevator car floor including a set of coupled elevator car floor modular elements; and
an elevator car roof including a set of coupled elevator car roof modular elements;
wherein the elevator car is configured to be supported in an elevator hoistway on at least one suspension member;
wherein the elevator car is configured to be moved through the elevator hoistway based on operation of a hoisting machine; and
wherein each set of the set of coupled elevator car floor modular elements and the set of coupled elevator car roof modular elements includes a plurality of adjacent modular elements configured to interlock together such that
the interlocked adjacent modular elements overlap in a direction that is orthogonal to a longitudinal direction extending through the interlocked adjacent modular elements, and
the interlocked adjacent modular elements have lower surfaces and upper surfaces that are coplanar at upper surface interfaces and lower surface interfaces between the interlocked adjacent modular elements, respectively, such that the interlocked adjacent modular elements form a structure that includes, on opposite surfaces of the structure, uniform surfaces that extend between the interlocked adjacent modular elements, respectively.

14. The elevator car of claim 13 , wherein,
at least one plurality of adjacent modular elements includes a first modular element and a second modular element that is adjacent to the first modular element,
the first modular element includes a protrusion,
the second modular element includes a recess that corresponds to the protrusion of the first modular element, and
the first and second modular elements are configured to interlock together such that the protrusion of the first modular element is nested in the recess of the second modular element.

15. The elevator car of claim 14 , wherein,
