[0002] During the construction or repair work of a building, people and goods need to be moved vertically so as to be able to carry out construction work on the upper part of the building. For example, construction workers need to move to the floor where their construction site is located and leave that floor. Similarly, goods such as tools, equipment, and construction materials need to be moved to the floor where the construction site of the corresponding tools, equipment, and construction materials is located. In addition, it may be necessary to transport people who are not involved in the construction work between floors.

[0003] Conventionally, the transportation of long construction materials is carried out by using a building crane and / or a temporary hoist and / or a temporary elevator installed outside the building under construction. People have been transported by a car operating in the hoistway of the building.

[0004] Such solutions have also been proposed, in which the structure of the elevator car is temporarily modified to transport long construction material objects. For example, such a solution is disclosed in EP3909897A1, where the car has a displaceable top plate for increasing the height inside the car.

[0005] The disadvantages of the known solutions for transporting long objects are that they are not good enough in terms of simplicity, efficiency, ease of use, and safety. Summary of the Invention

[0054] Figure 9 Illustrates when the lid has been displaced Figure 8 details of the structure of the transport box.

[0055] Figure 10 Illustrates Figures 1 to 5 a partial schematic upward-pointing three-dimensional view (only the upper part is visible) of the interior of the car of the lift and the interior of the transport box in Detailed Description

[0056] Figure 1 Illustrates a lift 100 according to an embodiment and a lift car 1 according to an embodiment, the lift comprising a hoistway 101. The lift car 1 is vertically movable in the hoistway 101.

[0057] The lift car 1 comprises a car body 2. The lift car 1 has a rear side (on the right side in Figure 1 ), and a front side (on the left side in Figure 1 ), the rear side and the front side being in particular on opposite sides of the vertical central plane c of the car 1. The car body 2 comprises an interior I1, a top plate 2a, walls 2b and a bottom plate 2c. The car body 2 comprises an access opening 2d on the front side of the car 1, in particular in the front wall 2b, the access opening 2d leading to the interior I1 of the car body 2 for allowing passengers and / or objects to move between the exterior of the car 1 and the interior I1 of the car body 2.

[0058] Furthermore, the lift car 1 comprises a transport box 3 on top of the car body 2, the transport box 3 comprising an interior I2. The transport box 3 comprises walls 31-34 and a lid 30 defining the interior I2.

[0059] Furthermore, the lift car 1 comprises a hatch 4 in the top plate 2a, the hatch leading from the interior I1 of the car body 2 to the interior I2 of the transport box 3 for allowing an object to be inserted into the car 1 such that the object extends from the interior I1 of the car body 2 through the hatch 4 into the interior I2 of the transport box 3. Furthermore, the lift car 1 preferably comprises an openable hatch door 6 or a panel covering the hatch 4, as Figure 1 shown.

[0060] The interior I2 of the transport box 3 and the hatch 4 are located on the rear side of the car 1, i.e. on the side of the car 1 opposite the aforementioned access opening 2d. Thus, long objects can be simply brought into the car 1. In particular, an object longer than the height of the interior I1 of the car body 2 can be moved head-first through the car access opening 2a and tilted and pushed such that the object moves head-upward and through the hatch 4 into the interior I2 of the transport box 3.

[0061] The lid 30 of the transport box 3 is non-horizontal. The non-horizontal lid 30 includes one or more inclined lid portions 30a, 30b that extend above the interior I2 of the transport box 3 and rise towards the rear of the car 1. Thus, the lid 30 of the transport box 3 does not invite people to stand on its top, which facilitates the safety of the car 1. If the transport box 3 has a large horizontal upper surface, maintenance personnel may be inclined to use it as a working platform and, during maintenance operations, dangerously manually drive the car 1 such that his head exceeds the intended safety clearance designed on top of the car. In a preferred embodiment, the interior I2 has an upwardly tapering cross-sectional profile, particularly as viewed in a direction transverse to the longitudinal direction of the car 1. This is visible, for example, in Figure 1 as shown. The length of the interior I2 in a direction transverse to the longitudinal direction of the car 1 is preferably at least 1 meter. Preferably, the length of the hatch 4 leading from the interior I1 to the interior I2 is preferably at least 1 meter in a direction transverse to the longitudinal direction of the car 1. Preferably, the length of the hatch 4 is at least 0.5 meter in the longitudinal direction of the car 1. These features individually and jointly facilitate that the interior I2 and the access to the interior I2 are spacious and can be arranged to easily receive and accommodate the head of an object extending from the interior I1 of the car 2 through the hatch 4 into the interior I2 of the transport box 3, and facilitate the formation of the upper side of the transport box such that it does not invite people to stand on its top.

[0062] In a preferred embodiment, one or more inclined lid portions 30a, 30b cover most of the interior I2 of the transport box 3, i.e., more than 50%. In the case shown, one or more inclined lid portions 30a, 30b completely cover the interior I2 of the transport box 3. The large area covered by the inclined portions enables the underlying interior I2 to easily receive objects that need to be inclined when bringing objects into the car 1 and also facilitates that the lid 30 does not induce maintenance personnel to use it as a working platform. Preferably, the area of the vertical projection of the inclined lid portions 30a, 30b and the area of the vertical projection of the interior I2 of the transport box 3 are greater than 1 m 2 .

[0063] In a preferred embodiment, by means of the above-mentioned inclined lid portions, an increase in the height h of the interior I2 towards the rear of the car 1 is achieved, particularly as a function of the horizontal distance from the front wall 2b including the access opening 2d. Thus, when bringing objects into the car 1, it can easily receive objects that need to be inclined and can facilitate that its upper surface is not used as a working platform.

[0064] The inclination angles of the inclined cover portions 30a, 30b are preferably relatively steep. Preferably, the inclined cover portions 30a, 30b rise towards the rear side of the car 1 at an angle greater than 30 degrees, more preferably greater than 40 degrees. However, preferably, the angle is less than 60 degrees, because in most cases, a very steep angle would make the interior I2 unnecessarily high. In a preferred embodiment, the angle is 45 degrees. In a preferred embodiment, the angle is constant, whereby the horizontal cross-section of the inclined cover portions 30a, 30b is straight. However, the angle can be made non-constant, and the cross-section of the inclined cover portions 30a, 30b is curved.

[0065] In a preferred embodiment, the cover 30 includes a hatch 30c and an openable door 30b covering the hatch 30c. In a preferred embodiment, the door 30b is an inclined cover portion.

[0066] Figures 2 to 4 Illustrated are the stages of a method for transporting an object in a building according to one embodiment. The method includes inserting the object 40 into the elevator car 1 of the elevator 100 such that the object extends from the interior I1 of the car 2 through the hatch 4 into the interior I2 of the transport box 3. This step is as Figure 2 shown. Referring to Figure 1 , the car 1 is as described above. After the insertion, the method includes vertically moving the car 1, such as from one landing to another landing, where the landings are at different floors of the building or at least lead to different floors of the building. This moving step is as Figure 3 shown. After the moving, the method includes removing the object from the car 1. This step is as Figure 4 shown.

[0067] In a preferred embodiment, the aforementioned object 40 is longer than the height of the interior I1 of the car 2.

[0068] In a preferred embodiment, as Figure 2 shown, the insertion is performed via the car access 2a. This is particularly performed such that the object 40 is moved head-first through the car access 2a, and the object 40 is tilted and pushed such that the head of the object moves upward and through the hatch 4 into the interior I2 of the transport box 3.

[0069] In a preferred embodiment, the removal is performed via the car access 2d, preferably to a landing located next to the car 1, or through the hatch 30c included in the cover 30 to a portion of the hoistway 101 located above the car 1. These alternatives for the removal have been shown in Figure 4 . During the removal, the car 1 preferably remains parked at the landing, particularly preferably such that the sill of the access 2d is flush with the sill of the landing.

[0070] Figures 5 to 8 FIG. illustrates a preferred embodiment of the transport box 3. The transport box 3 includes rigid side walls 31, 32 that extend vertically on opposite sides of the interior I2, and a rigid rear wall 33 that extends vertically on the rear side of the interior I2. These walls 31-33 are visible in Figure 6 and Figure 9 where the lid 30 does not obstruct visibility. The lid 30 is connected to the side walls 31, 32 and / or the rear wall 33, particularly to the upper edges of the side walls 31, 32 and / or the rear wall 33. In this case, the lid 30 can be displaced from its position where it extends above the interior I2. The rigidity of the walls allows them to stand firmly in place, providing a rigid structure and support for the lid 30. The walls 31-33 are rigidly connected to each other, whereby they together participate in forming the rigid frame structure of the transport box 3,

[0071] The side walls 31, 32 are vertical and parallel to each other. In addition to the rear wall 33, the transport box 3 further includes a front wall 34 that is vertical and parallel to the rear wall 33. In a preferred embodiment. Each of the side walls 31, 32, the rear wall 3 and the front wall 34 of the transport box 3 includes a vertical metal plate.

[0072] As described above, the lid 30 can be displaced from the position where the one or more inclined lid portions 30a, 30b extend above the interior I2 to a position, which is also referred to as the first position. In a preferred embodiment, the inclined lid 30 can particularly be displaced from its first position to a second position, in which one or more of the one or more inclined lid portions 30a, 30b extend horizontally and abut against the car top plate. In the second position, the lid portions 30a, 30b can be used as a working platform on which a person can stand. This position is disclosed in Figure 6 and Figure 9 Therefore, it is provided that the transport box 3 can be partially folded from one useful state, namely the lid 30 is in the first position, to another useful state, namely the lid 30 is in the second position.

[0073] In a preferred embodiment, the length of the side walls of the transport box 3 in the front-rear direction of the car 1 is greater than 0.5 meters, and the spacing in the direction transverse to the front-rear direction is greater than 1 meter, and when the lid 30 is displaced from its first position, in which the one or more inclined lid portions 30a, 30b extend above the interior I2, the side walls 31, 32 and the end wall 33 of the transport box define a working space on the top of the car 2 from the lateral sides, and the working space is at least 0.5 meters long and at least 1 meter wide. If a person stands between the walls 31-33, the walls 31-33 can facilitate the function of handrails. In addition to the transport box 3, the car 1 preferably further includes Figure 6 and Figure 7 handrails on the top of the car 2 not shown in the figure.

[0074] In a preferred embodiment, the cover 30 is detachably connected to a rigid frame structure, which includes the side walls 31, 32 and the rear wall 3 of the transport box 3. By being detachable, the mobility of the cover 30 is simply facilitated. The front wall 34 is also displaceable to make way for the positioning of the cover 30 to extend horizontally and abut against the car roof panel 2a.

[0075] As described above, the interior of the transport box 3 and the hatch 4 are located on the rear side of the car 1, i.e., on the side of the car 1 opposite to the aforementioned access 2d. In a preferred embodiment, the interior of the transport box 3 and the hatch 4 are more specifically fully located on the rear side of the vertical central plane c of the car 1, where the central plane is a vertical plane parallel to the front and rear walls of the car and extending through the centroid of the vertical projection of the car. This allows the other side of the car 1 to be used for other functions.

[0076] The following will be described Figure 1 Preferred additional features of the shown lift.

[0077] Preferably, the lift 100 includes lifting ropes [not shown] arranged to suspend the lift car 1. When the car 1 is as Figure 5 shown, the lifting ropes are arranged to suspend the lift car 1 via a pulley 50 included in the car 1. In this case, the lifting ropes are arranged to bypass the pulley 50 of the car 1.

[0078] Preferably, the lift 100 includes one or more guide rails [not shown] for guiding the movement of the car 1, and the car 1 includes a guiding member 60 arranged to move by sliding or rolling along the one or more guide rails.

[0079] Preferably, the lift 100 includes a motor [not shown] and a drive wheel [not shown] rotatable by the motor, and a lift control system [not shown] configured to control the movement of the car 1 in response to signals received from one or more user interfaces (such as user interfaces located at one or more landings and / or user interfaces located inside the car 1), in particular by controlling the rotation of the motor.

[0080] Generally, in this application, the features of the car 1 are described in a state where the car 1 is in an upright position.

[0081] Generally, a non-horizontal cover 30 may include a small horizontal portion, but in any case, it is preferred that the car 1 is such that the non-horizontal cover 30 does not include a horizontal upper surface with a length and width exceeding 0.2 m

[0082] As described above, in a preferred embodiment, the cover 30 is displaceable and / or the cover includes a hatch 30c and an openable door 30b covering the hatch 30c. However, one or both of these features may be omitted, since the cover may be permanently fixed above the interior I2 and the cover 30 need not have a hatch. Generally speaking, when the cover 30 is displaceable, it is preferred that the car 1 is provided with a safety switch for detecting the position of the cover 30 and the lift is arranged to stop and / or prevent further movement of the car in response to detecting displacement of the cover. Generally speaking, when the cover 30 includes an openable door 30b, it is preferred that the car 1 is provided with a safety switch for detecting the opening of the door 30b and the lift is arranged to stop and / or prevent further movement of the car in response to detecting the opening of the door 30b. In the first case, the safety switch is preferably connected to the safety chain of the lift and is arranged to cut the safety chain when the safety switch detects displacement of the cover 30. In the latter case, the safety switch is preferably connected to the safety chain of the lift and is arranged to cut the safety chain when the safety switch detects the opening of the door 30b.
