Description

Technical Field

[0001] The present invention relates to the field of elevators, in particular to the floor structure of a car of an elevator. Background Art

[0002] Companies operating in the elevator business usually have multiple elevator types in their product portfolio. The components of the elevator are usually tailored to the type of elevator. One of these components is the elevator's car, which includes multiple mechanical components. Due to the wide variety of elevators, multiple car models are required. Maintaining multiple independent car models may be inefficient from a manufacturing and cost point of view. Therefore, the coordination and modularization of the car is essential. The car includes multiple mechanical components, such as a floor assembly. The structure of the floor assembly can vary depending on the type of elevator. The modular platform structure of the floor assembly reduces the number of different types of mechanical components in different types of cars. However, the known modular platform solutions have many disadvantages.

[0003] Therefore, the floor structure of the elevator car requires a more complex modular solution.The present invention alleviates the disadvantages of the known solutions. Summary of the invention

[0012] The following embodiments are exemplary. Although the specification may refer to "one", "an" or "some" embodiments in several places in the text, this does not necessarily mean that each reference refers to the same embodiment, or that a particular feature applies to only a single embodiment. Individual features of different embodiments may also be combined to provide other embodiments.

[0013] The modular floor structure of the elevator car should be as simple as possible, but still strong enough to withstand mechanical stresses. The present invention provides a solution that is simple, strong and modular, and can therefore be expanded to meet different requirements.

[0014] According to one aspect of the present invention, there is provided a floor structure of a car of an elevator 100, comprising a first end 102A and a second end 102B and a first side 104A and a second side 104B, wherein each component 102A, 102B, 104A, 104B comprises a first end 102A_E1, 102B_E1, 04A_E1, 104B_E1 and a second end 102A_E2, 102B_E2, 1104B_E2, 104B_E2, which has at least a first integral interlocking element 106A and a second integral interlocking element 106B; wherein the first integral interlocking element 106A of the end 102A, 102B is configured to be coupled to the first integral interlocking element 106A of the side 104A, 104B , the second integral interlocking element 106B of the end portions 102A, 102B is configured to be connected to the second integral interlocking element 106B of the side portions 104A, 104B; wherein the first end 102A_E1 of the first end portion is configured to be connected to the first end 104A_E1 of the first side portion, and the second end 102A_E2 of the first end portion is configured to be connected to the first end 104B_E1 of the second side portion, and the first end 102B_E1 of the second end portion is configured to be connected to the second end 104A_E2 of the first side portion, and the second end 102B_E2 of the second end portion is configured to be connected to the second end 104B_E2 of the second side portion, so as to form a base plate structure 100 connected together at least by the integral interlocking elements 106A, 106B.

[0015] In an embodiment, the ends and sides may be made of steel pipes (tubes). The cross-section of the pipes may be substantially square. The pipe size may be selected as desired. The size and shape of the pipes used in the ends and / or sides may be different. For example, some parts of the structure may be made of pipes having different sizes.

[0016] Reference now Figure 1A, the bottom plate structure includes a first end portion 102A and a second end portion 102B, and a first side portion 104A and a second side portion 104B. The end portions and the side portions constitute a frame having a substantially rectangular shape. The first end portion and the second end portion have the same length, and the first side portion and the second side portion have the same length. The length of the end portion may be shorter than the length of the side portion. The end portions form first opposite sides of the frame structure, and the side portions form second opposite sides of the frame structure, and the first opposite sides and the second opposite sides of the frame structure together constitute a rectangle, such as Figure 1A shown.

[0017] Each end and side portion includes a first end 102A_E1, 102B_E1, 104A_E1, 104B_E1 and a second end 102A_E2, 102B_E2, 104A_E2, 104B_E2. Each end includes a first integral interlocking element 106A and a second integral interlocking element 106B. The first interlocking element 106A of the end portions 102A, 102B is configured to be coupled to the first interlocking element 106A of the side portions 104A, 104B. The second interlocking element 106B of the end portions 102A, 102B is coupled to the second interlocking element 106B of the side portions 104A, 104B, respectively. Therefore, each end of each portion includes at least two separate interlocking elements.

[0018] An integral interlocking element (also referred to herein as an interlocking element) refers to a feature formed on / from a part. It may be made of the material of the part. In other words, it may not be a separate feature coupled to the part. As described above, the ends and sides may be steel tubes, and the interlocking element may be formed, for example, by laser cutting. Laser cutting provides a very efficient and accurate method for forming different types of locking features on a part.

[0019] Reference now Figure 2A and Figure 2B . Figure 2A The first end 102A_E1, 102B_E1 of the end portion is shown. The first end and the second end of the end portion may be identical but mirror images of each other. The first end 102A_E1, 102B_E1 and the second end 102A_E2, 102B_E2 of the end portion each include a first interlocking element 106A and a second interlocking element 106B. Figure 2B The first end 104A_E1, 104B_E1 of the side portion is shown. The first end and the second end of the side portion can also be identical, but mirror each other like the two ends of the end portion. The first end 104A_E1, 104B_E1 and the second end 104A_E2, 104B_E2 of the side portion each include a first interlocking element 106A and a second interlocking element 106B.

[0020] Reference now Figure 1A, the first end 102A_E1 of the first end portion is configured to be connected to the first end 104A_E1 of the first side portion forming the first angle C1, and the second end 102A_E2 of the first end portion is configured to be connected to the first end 104B_E1 of the second side portion forming the second angle C2. The first end 102B_E1 of the second end portion is connected to the second end 104A_E2 of the first side to form a third angle C3, and the second end 102B_E2 of the second end portion is connected to the second end 104B_E2 of the second side portion to form a fourth angle C4. The first interlocking elements of the end portion and the side portion are connected together, and the second interlocking elements of the end portion and the side portion are also connected together to form a bottom plate structure. Therefore, each end (angle) of the end portion and the side portion is connected together by at least two interlocking elements.

[0021] refer to Figure 2C , which illustrates the ends of the ends and the ends of the side portions coupled together. When the ends of the portions are coupled together by the interlocking elements, the ends are substantially perpendicular relative to the side portions. In other words, the angle between the ends and the side portions is substantially 90 degrees. The ends may at least partially overlap.

[0022] The above structure is simple (fewer separate parts), but still very strong. Two integrated interlocking elements make the connection between each end of the parts very strong. Thus, the use of separate fastening members can be minimized. The above structure is telescopic according to different types of elevator cars.

[0023] In an embodiment, each end 102A, 102B and side 104A, 104B includes an outer wall, an inner wall, a top wall and a bottom wall 102A_W1-W4, 102B_W1-W4, 104A_W1-W4, 104A_W1-W4, wherein the first interlocking element 106A is arranged in the outer wall 102A_W1, 102B_W1, 104A_W1, 104B_W1 of the component 102A, 102B, 104A, 104B, and the second interlocking element is arranged in the inner wall 102A_W2, 102B_W2, 104A_W2 of the component 102A, 102B, 104A, 104B_W2. As described above, the component can form a structure having a rectangular shape, the inner wall refers to the wall of the component inside the rectangle, and the outer wall refers to the wall outside the rectangle opposite to the inner wall. The top wall is the wall at the top of the structure, and the bottom wall is the wall below the structure. The top of the structure is the side of the structure. Figure 1A and Figure 1B The middle is upward, the bottom is Figure 1A and Figure 1B The middle is downward.

[0024] like Figure 1BAs shown, the first end portion 102A includes an outer wall 102A_W1, an inner wall 102A_W2, a top wall 102A_W3, and a bottom wall 102A_W4. The second end portion 102B includes an outer wall 102B_W1, an inner wall 102B_W2, a top wall 102B_W3, and a bottom wall 102B_W4. The first side portion 104A includes an outer wall 104A_W1, an inner wall 104A_W2, a top wall 104A_W3, and a bottom wall 104A_W4. The second side portion 104B includes an outer wall 104B_W1, an inner wall 104B_W2, a top wall 104B_W3, and a bottom wall 104B_W4.

[0025] Reference now Figure 2A , Figure 2A The first end 102A_E1, 102B_E1 of the first end and the second end according to an embodiment are illustrated. The first interlocking element 106A is arranged in the outer wall 102A_W1, 102B_W1 of the end, and the second interlocking element 106B is arranged in the inner wall 102A_W2, 102B_W2 of the end. As mentioned above, the second ends of the first end and the second end can be mirror images from the first end, so the same principles can also apply to the second ends of the first end and the second end. Now refer to Figure 2B , Figure 2B The first ends 104A_E1, 104B_E1 of the first side and the second side according to an embodiment are shown. The first interlocking element 106A is arranged in the outer wall 104A_W1, 104B_W1 of the side, and the second interlocking element 106B is arranged in the inner wall 104A_W2, 104B_W2 of the side. As described above, the second end of the first side and the second end of the second side can be a mirror image from the first end, so the same principle can also be applied to the second end and the second side of the first side. Therefore, the first interlocking element and the second interlocking element are arranged on the opposite walls of the parts in the first end and the second end. This makes the connection between the ends very strong because the ends are connected from two distant points.

[0026] It is important to realize that although it is mentioned in this application that the ends, sides, and middle portions may be mirror images, this is not mandatory. For example, there may be some size and structural differences. Therefore, the features in the ends may vary depending on the range of embodiments described in this application.

[0027] refer to Figure 2C In an embodiment, the end and side top walls 102A_W3, 102B_W3, 104A_W3, 104B_W3 are at least partially configured to overlap near the first and second ends of the portions. Figure 2CThe first end portion 102A and the first side portion 104A are shown coupled together by interlocking elements 106A, 106B. The top wall 104A_W3 of the side portion extends below the top wall 102A_W3 of the first end portion, forming an overlapping section between the first end portion and the first side portion.

[0028] Reference now Figure 2D In an embodiment, the end and side bottom walls 102A_W4, 102B_W4, 104A_W4, 104B_W4 are at least partially configured to overlap near the first end and the second end. Figure 2D The first end 102A and the first side 104A are shown, which are connected together by interlocking elements 106A, 106B so that the bottom wall W4 is visible and upward. The bottom wall 102A_W4 of the end extends below the bottom wall 104A_W4 of the first side, forming another overlapping section between the first end and the first side.

[0029] In embodiments, the ends and sides may be fastened together from one or more overlapping sections by separate fastening members. Figure 2C and Figure 2D Only one corner of the structure formed by the first end and the first side is shown. The same principle applies to all other corners of the structure consisting of the end and the side.

[0030] See also Figure 1B In an embodiment, the floor structure 100 further comprises at least one middle portion 108, the at least one middle portion comprising a first end 108_E1 and a second end 108_E2 having a third integral interlocking element 106C, wherein the middle portion 108 is configured to be arranged between the first side wall 104A and the second side portion 104B, wherein the third interlocking element 106C of the middle portion 108 is configured to couple with the third interlocking element 106C arranged in the outer wall of the side portions 104A, 104B. The floor structure 100 may include more than one middle portion 108, for example, it may include two middle portions 108.

[0031] Reference now Figure 3A, which illustrates the first end 108_E1 of the middle portion. The second end 108_E2 of the middle portion can be substantially identical to the first end, but a mirror image. Therefore, the second end can have the same functions and features as described for the first end. The third interlocking element 106C of the middle portion 108 and the third interlocking element 106C of the side portions 104A, 104B may include two locking features. The third interlocking element 106C in the side portions 104A, 104B is configured to receive and accommodate the interlocking element of the middle portion, in other words, the third interlocking element 106C in the side portions 104A, 104B is the counterpart of the third interlocking element 106C of the middle portion 108. The third interlocking element 106C in the side portions 104A, 104B may be arranged in the outer walls 104A_W1, 104B_W1 of the side portions. As Figure 3C As shown, the third interlocking element 106C of the middle portion 108 is coupled to the third interlocking elements 106C of the side portions 104A, 104B.

[0032] In an embodiment, the middle portion 108 further comprises a fourth interlocking element 106D disposed in the first end 108_E1 and the second end 108_E2, wherein the fourth interlocking element of the middle portion 106C is configured to couple with the fourth interlocking element of the side portion 106C disposed in the inner walls 104A_W2, 104B_W2 of the side portion. Figure 3A , which illustrates the first end 108_E1 of the middle portion. The first end 108_E1 and the second end 108_E2 of the middle portion may include a fourth interlocking element 106D. The fourth interlocking element may include two locking features. Now referring to Figure 3B , the side portions 104A, 104B may further include a fourth interlocking element 106D, which is configured to be coupled to the fourth interlocking element 106D of the middle portion 108. The fourth interlocking element 106D in the side portions 104A, 104B may further include Figure 3B Two locking features are shown, which may be arranged in the inner walls 104A_W2, 104B_W2 of the sides.

[0033] Thus, the first end 108_E1 and the second end 108_E2 of the middle portion may include two interlocking elements 106C, 106D, which are configured to couple with the respective two interlocking elements 106C, 106D of the side portions 104A, 104B. Each interlocking element may include two locking features. This ensures that the middle portion is securely connected to the side portions and provides strong support for the structure.

[0034] In an embodiment, Figure 1B and Figure 3AAs shown, the middle portion 108 includes a first side wall, a second side wall, a top wall and a bottom wall 108_W1, 108_W2, 108_W3, 108_W4, wherein the third interlocking element 106C is arranged in the side walls 108_W1, 108_W2 of the middle portion. Figure 3A , the third interlocking element 106C of the middle part 108 may include two locking features, one of which is arranged in the first side wall 108_W1 and the other in the second side wall 108_W2. Therefore, both side walls 108_W1, 108_W2 of the middle part may include one locking feature of the third interlocking element 106C.

[0035] refer to Figure 3A , the fourth interlocking element 106D is arranged in the side walls 108_W1, 108_W2 and / or the bottom wall 108_W4 of the middle part. As described above, the fourth interlocking element 106D of the middle part 108 may include two locking features, one of which is arranged in the first side wall 108_W1 and the bottom wall 108_W4 of the middle part, and the other is arranged in the second side wall 108_W2 and the bottom wall 108_W4 of the middle part.

[0036] In an embodiment, the top wall 108_W3 of the middle portion at least partially overlaps with the top walls 104A_W3, 104B_W3 of the side portions. Figure 3C As shown, near the first end 108_E1 and the second end 108_E2 of the middle portion, the top wall 108_W3 of the middle portion extends above the top walls 104A_W3 and 104B_W3 of the side portions. In another embodiment, the bottom wall 108_W4 of the middle portion at least partially overlaps with the bottom walls 104A_W4 and 104B_W4 of the side portions. Figure 3E The bottom wall 108_W4 of the middle portion extends inside the side portions 104A, 104B and extends above the bottom walls 104A_W4, 104B_W4 of the side portions near the first end 108_E1 and the second end 108_E2 of the middle portion. The overlapping sections can be used to connect the middle portion and the side portions together by separate fastening members.

[0037] refer to Figure 2AIn an embodiment, the first interlocking element 106A and the second interlocking element 106B in the end portions 102A, 102B include protrusions 112A, 112B extending toward the bottom walls 102A_W4, 102B_W4 of the end portions. The protrusions of the first interlocking element 112A may be arranged in the outer walls 102A_W1, 102B_W1, and the protrusions of the second interlocking element 112B may be arranged in the inner walls 102A_W2, 102B_W2. The first interlocking element 106A of the side portions 104A, 104B may also include protrusions extending toward the top surfaces of the side portions 104A_W3, 104B_W3. The first protrusions of the ends may then extend in opposite directions. In other words, the first interlocking element 106A forms a hook-shaped structure that can be coupled together, such as Figure 2C shown.

[0038] refer to Figure 2B The protrusion 112 mentioned in the present application may be formed into a hook-shaped structure having a cavity CA between the protrusion and a counterpart configured to receive the protrusion. Figure 2B The side is illustrated, and in this case, the base part refers to the side, or more specifically to the outer wall 104A_W1, 104B_W1 of the side. Therefore, when the counterpart is set into the cavity, the hook-like structure formed by the protrusion prevents and / or limits the movement of the counterpart. The counterpart can only enter and exit the cavity, so basically it can only move in one direction. This principle may apply to all interlocking elements with protrusions in the present application. The end 102A, 102B and the first interlocking element 106A of the side 104A, 104B can all be protrusions, and then the cavity of one interlocking element is set in the cavity of another interlocking element to form a protrusion. Figure 2C Connections shown.

[0039] Reference now Figure 2B , the second interlocking element 106B in the side portions 104A, 104B may include a slot (hole) configured to receive a protrusion of the second interlocking element 106B of the end portions 102A, 102B. Figure 2C In the embodiment, the second interlocking elements 106B of the end portions 102A, 102B are coupled with the second interlocking elements 106B of the side portions 104A, 104B. In other words, the protrusions are located in the grooves that restrict the relative movement of the portions.

[0040] Figure 3A An embodiment is shown in which the third interlocking element 106C in the middle portion 108 includes a protrusion 112C extending toward the bottom wall 108_W4 of the middle portion. As described above, the first and second ends of the middle portion may include two locking features, which may be protrusions. Figure 3AAs shown, the first protrusion 112C can be arranged in the first side wall 108_W1 of the middle part, and the second protrusion 112C can be arranged in the middle part 108_W2 of the second side wall. Therefore, the two side walls of the middle part can include protrusions extending toward the bottom wall of the middle part. The third interlocking element 106C in the side parts 104A, 104B can include a groove configured to receive the protrusion 112C. As described above, the groove can be arranged in the outer wall of the side parts 104A, 104B. The connection between the third interlocking element of the middle part and the side parts is Figure 3C In the embodiment of the present invention, the projections arranged in the middle part are assembled in the grooves of the side parts, the projections being locked against the outer walls of the side parts in the assembled state. The assembled state refers to the situation in which the parts are coupled together according to the invention.

[0041] Reference now Figure 3B , the fourth interlocking element 106D in the side 104A, 104B includes a protrusion 112D extending toward the top wall 104A_W3, 104B_W3 of the side. The protrusion 112D can be arranged in the bottom wall 104A_W4, 104B_W4 of the side, extending toward the top wall 104A_W3, 104B_W3. The protrusion 112D can be connected to the inner wall 104A_W2, 104_W2 of the side and / or formed by the inner wall. As described above, the fourth interlocking element can include two locking features. Therefore, there can be two protrusions 112D in the side 104A, 104B. Now referring to Figure 3A , the fourth interlocking element 106D of the middle portion 108 may include one (or more) grooves configured to receive the protrusions 112D of the fourth interlocking element 106D of the side parts 104A, 104B. If there are two protrusions 112D on the side parts 104A, 104B, the middle portion may also include Figure 3A , 3B Two grooves are shown. One groove may be arranged in the first side wall 108_W1 and the bottom wall 108_W4 of the middle part, and another groove may be arranged in the second side wall 108_W2 and the bottom wall 108_W4 of the middle part.

[0042] In the embodiment, the first interlocking element 106A is located near the bottom wall 102A_W4, 102B_W4, 104A_W4, 104A_W4 of the end and the side, and the second interlocking element 106B is located near the top wall 102A_W3, 102B_W3, 104A_W3, 104B_W3 of the end and the side. Therefore, the first interlocking element 106A and the second interlocking element 106B of each corner of C1, C2, C3, C4 are arranged at different positions in the height direction H of the base plate structure. This means that the interlocking elements of the corners are spaced apart from each other in the height direction, which makes the connection of the end and the side strong and durable.

[0043] refer to Figure 2C , the ends 102A, 102B and the sides 104A, 104B can be connected to the first interlocking element 106A and the second interlocking element 106B at each corner of C1, C2, C3, and C4, so that the ends and the ends of the sides (for example, the first end 102A_E1 of the first end and the first end 104A_E1 of the first side) are arranged together in the height direction H of the floor structure 100. Then, the first interlocking elements 106A are locked together, and the second interlocking elements 106B are locked together. For example, the protrusions of the first interlocking element 106A and the sides 102A, 102B, 104A, and 104B are locked together, and the protrusions of the second interlocking element 106B at the ends 102A and 102B are locked together with the grooves of the second interlocking element 106B of the sides 104A and 104B.

[0044] Therefore, when the two ends of the end and the side are connected together, the parts move in the height direction.When these parts are connected together by interlocking elements, this is the only direction in which they can move.Interlocking elements prevent movement in other directions.In addition, the top wall 102A_W3, 102B_W3, 104A_W3, 104B_W3 of the end and the side and the bottom wall 102A_W4, 102B_W4, 104A_W4, 104B_W4 of the end and the side are configured to overlap.The overlapping section of the end and the side (on the top wall and the bottom wall) can be fastened together by the separating fastening member such as screws.The fastening member also prevents the movement of the end and the side in the height direction.Then, each angle formed by the end of the end and the side is firmly connected together by the interlocking element, and is further connected together by the separating fastening member.

[0045] refer to Figure 3B , Figure 3C , Figure 3D and Figure 3E The middle portion 108 is coupled to the side portions 104A, 104B so that the ends 108_E1, 108_E2 of the middle portion enter the interior of the side portions 104A, 104B. The side portions 104A, 104B may include an opening 116 configured to receive a Figure 3B When assembling the middle part 108 with the side parts 104A and 104B, the ends 108_E1 and 108_E2 of the middle part are moved vertically into the openings 116 of the side parts 104A and 104B, so that the third interlocking element 106C (protrusion) of the middle part 108 enters the third interlocking element 106C (groove) of the side parts 104A and 104B. Then the middle part 108 is moved downward to connect the third interlocking elements together and the fourth interlocking elements together, respectively, as shown in FIG. Figure 3C and Figure 3DAs shown. Then, the middle part 108 can only move in the height direction H of the base structure relative to the side parts 104A, 104B, and the interlocking elements prevent movement in other directions. The top wall 108_W3 of the middle part and the top walls 104A_W3, 104B_W3 of the side parts, and the bottom wall 108_W4 of the middle part and the bottom walls 104A_W4, 104B_W4 of the side parts are arranged to overlap when the middle part and the side parts are connected together. The overlapping sections of the middle part and the side parts can be fastened together in the same way as the corners of the base structure by separate fastening members. This prevents the movement of the middle part and the side parts in the height direction, and together with the interlocking elements, a very strong connection is formed to support the base structure.

[0046] Reference now Figure 4A In an embodiment, the floor structure 100 further comprises a floor 114 configured to be arranged on the top of the floor structure 100, the floor structure 100 being formed by at least the end portions 102A, 102B and the side portions 104A, 104B, wherein the floor 114 comprises at least one fifth interlocking element 106E configured to be connected to a fifth interlocking element of the side portion 106E arranged in the top wall 104A_W3, 104B_W3 of the side portion. For example, the floor can be made of a metal plate. For example, it can also include a reinforcing element. As in Figure 4A As described above, the base plate 114 is configured to be assembled on top of the base frame structure 100. For example, Figure 1A , Figure 1B and Figure 4A , the top surface / surface of the structure faces upward. The fifth interlocking element 106E in the bottom plate 114 may be arranged near the edge of the bottom plate 114, such as Figure 4B As shown. The overall size of the bottom plate 114 can be slightly smaller than the overall size of the bottom plate structure 100. Then, each edge of the bottom plate 114 is located above the top walls 102A_W3, 102B_W3, 104A_W3, 104B_W3 of the end and / or side portions. The top walls of the side portions 104A, 104B can also include one or more fifth interlocking elements 106E, which correspond to the fifth interlocking elements 106E of the bottom plate 114. For example, this Figure 2C Therefore, when the bottom plate 114 is assembled on top of the frame 100, the fifth interlocking element 106E in the side edge of the bottom plate 114 can be connected with the fifth interlocking element 106E of the top wall 104A_W3, 104B_W3 of the side.

[0047] exist Figure 4B In the illustrated embodiment, the fifth interlocking element 106E of the bottom plate 114 includes a protrusion 112E extending in the longitudinal direction of the bottom plate / structure 1. The fifth interlocking element 106E of the side portions 104A, 104B may include a slot configured to receive the protrusion 112E of the fifth interlocking element 106E of the bottom plate 114.

[0048] See also Figure 4C , the bottom plate 114 can be assembled with the bottom plate structure so that the bottom plate is set on the top of the bottom plate structure and the fifth interlocking element of the bottom plate is aligned with the side. Then, the fifth interlocking element (protrusion) of the bottom plate enters the fifth interlocking element (groove) of the top wall of the side. The plate can move in the longitudinal direction L of the bottom plate 114 so that the top wall of the side enters the cavity of the protrusion. Then, the fifth interlocking element is connected together to limit the movement of the bottom plate relative to the bottom plate structure. In an embodiment, the bottom plate can be fastened with the bottom plate structure or with a separate fastening member.

[0049] The separate fastening members mentioned in the present application may be mechanical and / or chemical fasteners, such as screws and / or glue.

[0050] The floor structure of the present invention solves many disadvantages of known solutions. Due to the integrated interlocking elements, fewer separate fastening components are required in the assembly, so the floor structure is cheaper and faster to manufacture. The shape and position of the integral interlocking elements in the floor structure make the structure very strong and secure. The floor structure provides a platform solution for the car floor assembly that is suitable for different types of elevators. The floor structure is modular and expandable, allowing it to adapt to different types of dimensional requirements.
