[0059] Figure 1a It is a schematic side view of a partial cross-section of an elevator car, and Figure 1b yes Figure 1aAnother schematic side view of the elevator car shown. It should be noted that only the lower part of the elevator car is shown in the figure.
[0060] The elevator car 100 includes a car floor 1, car side walls 20, and a car top (not shown). The car floor 1 is divided into at least two sections. The at least two sections include at least one openable section 2. In one embodiment, for example... Figure 1a , 1b As shown, the car floor has three sections: two openable sections 2 and another section 3 arranged between the two openable sections 2. The other section 3 may be a fixed section, which is attached to the structure / frame 9 of the elevator car so that it cannot be opened or removed without tools.
[0061] The openable section 2 provides access from the interior of the elevator car 100 to the exterior of the car via a floor opening 4. This allows, for example, maintenance and repair work concentrated on the underside of the elevator car and / or concentrated in the pit 24 of the shaft from inside the elevator car. The opening is sized to prevent personnel performing maintenance and repair work from slipping or falling into the pit.
[0062] The openable section 2 includes a movable floor element 5, which is positioned in a closed position (e.g., Figure 1a , Figure 1b When the floor element shown on the right is closed, the floor opening is closed, and when it is arranged to the open position (such as...) Figure 1b When the floor element shown on the left is in the middle, it allows access to the floor opening 4.
[0063] The guide device 6 is arranged to slidably guide the movable floor element 5 from a closed position to an open position. In one embodiment, such as Figure 1a , 1b As shown, the guide device 6 guides the movable floor element 5 at least partially above another floor section 3, as... Figure 1b As shown. Preferably, guide devices 6 are present at both ends of the movable floor element 5. In an embodiment particularly suitable for large elevator cars, at least one guide device is provided in the central portion of the movable floor element 5.
[0064] In one embodiment, the fixed floor section 3 is sized relative to the movable floor element 5 such that two openable sections 2 can be arranged side-by-side in their open positions simultaneously.
[0065] In one embodiment, the guiding device 6 includes a guide body 7 having an elongated shape in the direction of movement of the movable floor element 5 and a follower element 8 that moves in or on the guide body 7.
[0066] In one embodiment, the guide body 7 includes a guide rod. In one embodiment, the guide body 7 includes a track. In one embodiment, the guide body 7 includes a slide.
[0067] In one embodiment, such as Figure 1a , 1b As shown, the follower element 8 includes a guide roller 10. In one embodiment, the follower element 8 includes a dummy element or a guide pin.
[0068] In one embodiment, such as Figure 1a , Figure 1b As shown, the follower element 8 is arranged below the movable floor element 5, and the guide 7 is arranged in the structure / frame 9 surrounding the floor opening 4 of the elevator car. However, the reverse arrangement is also possible, in which the follower element 8 is located in the structure / frame 9 surrounding the floor opening of the elevator car, while the guide 7 is arranged in the movable floor element 5.
[0069] In one embodiment, the guide body 7 includes a first segment 11 and a second segment 12, wherein the follower element 8 is located in the first segment 11 when the movable floor element is in its closed position, and in the second segment 12 when the movable floor element is in its open position. The first segment and the second segment 12 engage, allowing the follower element to easily move from one segment to the other and back. Segments 11 and 12 are arranged to lift the follower element and the movable floor element 5 upward as the follower element 8 moves from the first segment 11 to the second segment 12.
[0070] In one embodiment, such as Figure 1a , Figure 1b As shown, the length and direction of the first section 11 of the guide body at least substantially correspond to the length and direction of the sliding movement of the movable floor element 5. The second section 12 of the guide body is arranged at the upper end of the raised section 13 extending upward from the first section 11 toward the car floor 1. The follower element 8 is arranged at, or at least substantially close to, the first edge 14 of the movable floor element located distal to the fixed section 3.
[0071] In one embodiment, the guide device 6 includes a stop structure 16 that stops the movement of the follower element 8 within the guide body 7 once the open position is reached, thereby stopping the movement of the movable floor element 5. In one embodiment, the stop structure 16 includes a section of the guide body in which at least one of the height and width is restricted, making it impossible for the follower element 8 to pass through the section. In one embodiment, the stop structure 16 includes an element extending within the guide body 7 and forming an obstacle that stops the follower element 8.
[0072] In one embodiment, at least one roller 17 is arranged on the underside of the movable floor element 5. In another embodiment, a plurality of rollers 17 are distributed across the entire width of the movable floor element 5. As the movable floor element 5 moves on the fixed element, the rollers contact its upper surface. The circumference of the rollers is preferably made of a softer material than the fixed element, thus preventing scratches from the fixed element.
[0073] In one embodiment, the elevator car 100 includes a skirt 19 at the junction of at least one of the car floor 1 and the car walls 20 (typically at all walls of the elevator car). In one embodiment, at least some sections of the skirt 19 are detachably arranged to the junction of the car floor and at least one wall, and an edge of the movable floor element 5 extends below the detachable sections. The skirt 19 prevents the movable floor element 5 from moving to the open position because it does not allow the movable floor element to rise. By removing the skirt 19 from the junction, the movable floor element 5 can be moved to the open position.
[0074] In one embodiment, for example, Figure 1a , 1b As shown, the first edge 14 of the movable floor element extends below the removable skirt 19. In one embodiment, at least one of the side edges extends below the removable skirt 19. The side edges are the edges that connect the first edge 14 of the movable floor element to the second edge 15.
[0075] In one embodiment, actuator 21 is arranged in the structure / frame 9 of the elevator car for lifting a second edge 15 of the movable floor element. The second edge is the edge near or close to the fixed section 3 when the movable floor element is in its closed position. When the second edge 15 is lifted, the movable floor element 5 slides more easily on the fixed section 3. In one embodiment, the actuator comprises a mechanical spring. In another embodiment, the actuator comprises a gas spring.
[0076] In one embodiment, the movable floor element 5 can be locked to its closed position by a locking system 22. In one embodiment, the locking system 22 includes a lock disposed on the movable floor element 5 for locking to the elevator car structure / frame 9. In one embodiment, the locking system 22 is arranged to lock the skirt 19 in the joint between the car floor 1 and the car wall 20, and the skirt prevents movement of the movable floor element as described above in this specification. In one embodiment, the locking system 22 is operated by a triangular key.
[0077] Figure 2a and 2bThis is a schematic side view of an embodiment of the guiding device. The relative positions of the guide body 7 and the follower element 8, and their positions relative to the movable floor element 5, can be arranged in various ways. Some of these embodiments...

The second section 12 of the guide engages the upper end of the first section 11 and extends at least substantially horizontally toward the fixing element 18. An actuator (not shown) may be added to lift the second edge 15 upwards to aid in the movement M of the movable floor element above the fixing element 18 (shown by dashed lines).
[0079] Figure 3a and 3b This is a schematic side view of another embodiment of the guiding device. In some embodiments, such as Figures 1a-1b As shown in 2a-2b, the follower element 8 is arranged at or at least substantially close to the first edge 14 of the movable floor element. In another embodiment, the follower element 8 is arranged in the middle section of the movable floor element 5, i.e., somewhere between the first edge 14 and the second edge 15 of the movable floor element. In one embodiment, such as Figure 3a , 3b As shown, the follower element 8 is located midway between the first and second edges of the movable floor element. The position of the follower element 8 requires that the guide body 7 be partially positioned below or near the fixed element 18.
[0080] Figure 4a and 4b This is a schematic side view of a third embodiment of the guiding device. The follower element 8 is arranged to, or at least substantially near, the second edge 15 of the movable floor element. The guide body is positioned below or near the fixing element 18.
