Description

Technical Field

[0001] This invention relates to a car for an elevator system, having an interior space for people to stay in, a car roof defining the interior space in the upper direction and allowing people to walk, the car roof having a car roof hatch that can be opened in the upper direction, and a suspended ceiling arranged below the car roof, the suspended ceiling having a suspended ceiling hatch that can be opened in the lower direction. The invention also relates to an elevator system having at least one vertically extending elevator shaft with multiple stop doors and the aforementioned car. Furthermore, the invention relates to a method for evacuating people located in the aforementioned car in such an elevator system, and a method for self-evacuation from the aforementioned car. Background Technology

[0002] Elevator systems, used for the vertical and / or horizontal transport of people and / or the transfer of goods, are an integral part of modern residential and commercial buildings. A typical elevator system includes one or more elevator shafts in which one or more cars move between stopping positions by means of a drive mechanism. The drive mechanism may be, for example, a driven traction sheave that drives one or more suspension devices, or a linear drive.

[0003] In such elevator systems, it is known that measures must be taken to ensure the evacuation of people from the car in the event of a malfunction within the elevator shaft. This is typically achieved by entering the car through an adjacent higher stop, across the car roof, and through a hatch located within the car roof. During this process, if a downward-opening hatch, such as one with a downward-opening flap, is opened, it must be ensured that it does not fall on people standing below and potentially cause injury.

[0004] In the event of a fire, especially for so-called fire elevator cars that should be operated by firefighters, it is also necessary to be able to evacuate on its own in case of malfunction.

[0005] The drawback of existing fire elevator cars is that they are not inherently designed as fire-fighting elevator cars because their known structural designs contain shortcomings that are not acceptable for all cars in multi-car elevator systems. Therefore, manufacturers must manage fire-fighting elevator cars as an additional model series that incurs corresponding extra costs. For example, one drawback is the limited interior space of existing fire-fighting elevator cars, resulting in reduced elevator shaft utilization.

[0006] EP 3 604 197 B1 discloses a car with an inwardly opening flap, wherein the opening process can be controlled from the top of the car by means of a strap.

[0007] JP 2001 171 932 A also discloses a car for elevator equipment having a car top hatch and a folding ladder connected to the car top hatch for access from inside the car to the top of the car. Summary of the Invention

[0008] In light of this, the object of the present invention is to provide a car that is constructed as a fire elevator car and can avoid the aforementioned disadvantages compared to a car that is not configured as a fire elevator car.

[0009] The object of this invention is achieved through its independent sovereignty feature. Advantageous embodiments are given in the dependent claims. The teachings of the dependent claims may be combined with the teachings of the independent and dependent claims in any way, provided it is technically feasible.

[0010] Specifically, this objective is thus achieved by a car for an elevator system, the car having: an interior space for occupants to stay in; a car roof defining the interior space in the upper direction and allowing passage for people; the car roof having a car roof hatch that can be opened in the upper direction; and a suspended ceiling arranged below the car roof having a suspended ceiling hatch that can be opened in the lower direction, wherein the car roof hatch and the suspended ceiling hatch form a passage between the interior space and the car roof, wherein the suspended ceiling hatch includes a flap that is connected to the suspended ceiling on a first side by means of a hinge, and is accessible on a second side by means of a hinge. The closing device is releasably connected to the ceiling, wherein a first receiving portion is formed on the second side of the flap and a second receiving portion is formed on the ceiling, wherein in the closed position of the flap, a releasable retaining device is arranged between the first and second receiving portions for limiting the opening angle of the flap, wherein the retaining device has at least one first pulling device for release, and wherein in the limited open position of the flap limited by the retaining device, at least one pulling device is arranged to be accessible from the car top and at least one pulling device is arranged to be accessible from the interior space.

[0011] The advantages of the claimed invention will now be explained, and preferred embodiments of the invention will be further described below. The explanations, particularly those concerning advantages and feature limitations, are largely descriptive and exemplary, not restrictive. If an explanation is restrictive, it will be explicitly stated.

[0012] As long as elements are labeled with numbers, such as "first element," "second element," and "third element," this numbering is purely for distinguishing by name and does not indicate any interdependence between elements or a mandatory order of elements. This specifically means, for example, that an apparatus or method does not necessarily need to have a "first element" to have a "second element." The apparatus or method may also have both a "first element" and a "third element," without necessarily having a "second element." Multiple units of a single numbered element can also be provided, such as multiple "first elements."

[0013] Elevator equipment specifically includes at least one vertically extending elevator shaft with multiple stop doors, particularly on multiple floors of a building. The car thus has a car door, for example, on the front. The car door is configured to interact with stop doors at the car's stop positions to form access to the car, wherein the car transports passengers or goods between stop positions during normal operation. The car may also have multiple car doors, for example on the front wall and one or both sides, so that they can interact with stop doors at multiple sides of the elevator shaft.

[0014] The car is therefore specially designed as a compartment with four side walls, a floor and a roof, which surround the interior space, with one or more side walls forming the car door.

[0015] The car top hatch and ceiling hatch are specifically designed as rectangular openings, sized to allow personnel to climb through. Particularly preferably, the car top hatch and ceiling hatch are at least approximately the same size and are constructed aligned with each other. Where the car top hatch is openable, it is specifically provided with a flap or a sliding or fully removable cover. Opening is achieved by pivoting the flap upwards, or by lifting the cover and then sliding it to one side or removing it completely. The ceiling hatch can be opened via a flap assigned to it, which allows it to pivot into the interior space, i.e., downwards.

[0016] The closure device should be understood as a means by which the second side of the flap can be temporarily and thus releasably held to the ceiling. In particular, the closure device forms a form fit and / or force fit between the flap and the ceiling.

[0017] The receiving portion should be understood as a means by which the retaining device can be held in the broadest sense by force engagement and / or form engagement. In particular, the receiving portion is formed as a notch or protrusion, such as a slit, groove, hook, or the like. As long as the retaining device is arranged between the first and second receiving portions, it is force-engaged and / or form-engaged with both receiving portions respectively.

[0018] In the closed position, the flap is located within the ceiling hatch, thus forming a continuous plane with the ceiling. Here, the components of the closing device assigned to the flap and the ceiling are positioned relative to each other to allow the closing device to be closed. In the limited open position, the flap is opened to the opening angle created by the restriction. That is, the dimensions of the first retaining device are set such that the first and second receiving portions, or the second side of the flap and the ceiling, can be spaced apart by a distance, after which the retaining device prevents further movement away. Specifically, the opening angle determined by the retaining device in the limited open position is selected / determined such that the flap only extends into the interior space to a specific clearance height sufficient to avoid contact with personnel of average height, while the opening angle is sufficient to ensure access to the pulling device from the interior space.

[0019] Retaining devices are particularly made of textiles, plastics, metals, or similar sturdy materials, such as straps, wires, rods, or the like. A pulling device is a mechanism that allows a person to release the retaining device by pulling it by hand, such as a pull strap or cord.

[0020] Achieving this objective using the aforementioned car now includes the following technical teaching: during evacuation from the car roof, the flap opening into the interior space is first opened to a limited opening position, allowing occupants inside the car to be aware of the impending full opening of the flap and to identify how they must position themselves relative to the flap within the interior space to avoid contact upon full opening. In this way, when the flap is opened from the car roof by personnel standing on the roof during evacuation, occupants will not be startled by the full opening of the flap. When the flap is in the limited opening position, personnel standing on the car roof can directly communicate with occupants inside the interior space, and / or occupants can avoid the flap before the retaining device is released and the subsequent full opening occurs. Therefore, with the aid of the retaining device, the risk of injury from the flap is reduced or avoided during evacuation by personnel standing on the car roof. Simultaneously, the retaining device is constructed to also be opened from the interior space by means of a pulling mechanism, thus the car is suitable for self-evacuation by occupants within the interior space. Therefore, this car can also be used as a fire elevator car without structural changes to the holding device or the ceiling hatch, without the disadvantage of reducing the car's practicality.

[0021] In one embodiment, the retaining device has only a first pulling device, which is arranged to be accessible from both the car top and the interior space. For example, the first pulling device can be arranged such that, in the closed position of the flap, it can be reached and grasped from the car top to bring the flap to a limited open position; otherwise, when moving the flap to the limited open position, the pulling device will slide or fall, making it accessible from the interior space. Here, even in the limited open position, the first pulling device is still accessible from the car top; however, compared to the closed position of the flap, its accessibility may undergo a slight adverse change due to the sliding or falling of the pulling device.

[0022] In an alternative embodiment of the car, the retaining device further includes a second pulling device for release, wherein in the limited open position of the flap restricted by the retaining device, the first pulling device is arranged to be accessible from the car top, and the second pulling device is arranged to be accessible from the interior space. Thus, at any position of the flap, one pulling device can be easily and very advantageously accessed from the car top and from the interior space, respectively.

[0023] In one embodiment of the car, the retaining device has a fixing element for determining the position of the retaining device on the first and / or second receiving portion. This allows for easy positioning of the first or multiple pulling devices for access from the car top and from the interior space, and in particular ensures that the retaining device does not slip out of its corresponding position. In a preferred design, the fixing element is formed as a loop and wrapped around the first or second receiving portion. It is therefore particularly simple to construct and can be secured to the receiving portion.

[0024] In another embodiment of the car, the retaining device is formed as a ring. The ring can be held between the first and second receiving parts in a simple manner, particularly by wrapping around the receiving parts or certain areas of the receiving parts. Furthermore, the ring can be folded in the closed position of the flap, so that it does not cause obstruction or obstruction to adjacent components of the car in the closed position. At the same time, the retaining device formed as a ring can be unfolded when the flap is partially opened, and the opening angle is limited by its fully unfolded arrangement.

[0025] In one of the aforementioned embodiments, the ring is formed by a first partial ring and a second partial ring, wherein in the closed position or partially open position of the flap, a first region of the first partial ring is connected to a first region of the second partial ring, and a second region of the first partial ring is connected to a second region of the second partial ring. For example, the ring is formed by a first strap with two Velcro areas as the first partial ring and a second strap with two corresponding Velcro areas as the second partial ring, wherein these two straps together form the ring. In one embodiment with two pulling devices, the first region can then be easily engaged with the first pulling device, and the second region with the second pulling device, so that the pulling devices can be arranged or operated separately on the retaining device, thereby enabling the accessibility of each respective pulling device independently.

[0026] In an alternative embodiment, the ring is formed in one piece, wherein a first region of the ring is connected to a second region of the ring in the closed or partially open position of the flap. For example, the ring is formed from a strip of tape with two corresponding Velcro areas, which forms a loop with itself. In an embodiment with only one pulling device, the retaining device is thus simplified in construction.

[0027] In another embodiment of the car, the first and / or second receiving portions are formed as slits through which the retaining device passes. This embodiment provides a particularly simple solution for the receiving portion, wherein the arrangement of the retaining device is simplified by pulling it through the slit, there is a secure form fit between the receiving portion and the retaining device in all directions, and wherein the retaining device can be easily released from the receiving portion after being released via the first or one of the pulling devices, thereby fully opening the flap.

[0028] In another embodiment, the car also has a variable-sized ladder, particularly an extendable telescopic ladder, wherein the ladder, in its stored position, is fully positioned between the car roof and the ceiling hatch within the passageway area. Whenever the ladder's dimensions are variable, it includes a mechanism by which it can be brought into a compact arrangement not in use and into an extended arrangement for use. For this purpose, in particular, the sections of the ladder are folded or slid relative to each other. Within the meaning of this invention, this means that the ladder is always, i.e., in each arrangement and between two arrangements, one piece, without the need for the sections to be separated or assembled. In particular, the ladder is designed and constructed to be in a compact arrangement in the stored position, or the car is constructed such that the ladder is in a compact arrangement in the stored position.

[0029] The storage location is preferably designed so that the ladder is securely held to the car, thus eliminating the possibility of collisions with other components of the elevator system during car movement. As long as the ladder is positioned entirely between the car top and the ceiling hatch within the passageway area, this means that no part of the ladder will protrude beyond the plane of the car top or the ceiling.

[0030] Advantageously, the ladder can be used for evacuation by personnel located on the car top or for self-evacuation by personnel located inside the interior space, as required for fire elevator cars, or accessible from the car top or interior space when the car top hatch or ceiling hatch is open. Here, the ladder is arranged in the space between the car top and the ceiling so as not to adversely affect the usability of the car, particularly in terms of available interior space.

[0031] In one of the aforementioned embodiments, in the limited open position of the flap, a pull device accessible from the car top for releasing the retaining device is held on the ladder or ceiling hatch. If the ladder is held on the car top and / or ceiling so that its storage position is unaffected by the opening of the car top hatch and / or ceiling hatch, the pull device is held in an area particularly easily accessible from the car top, and therefore particularly easy to access. This easily accessible and thus particularly well-visible pull device allows personnel standing on the car top to directly and visually identify how to operate the ceiling hatch to further open, which is particularly advantageous when considering the foreseeable pressure conditions during evacuation.

[0032] In another embodiment of the elevator car, a pull device accessible from the interior space is suspended within the interior space when the flap is in the partially open position. Therefore, it is configured, for example, when the flap is in the closed position, to descend via the opening of the flap when it is brought into the partially open position. Because the pull device is suspended, it is easily accessible and operable by personnel inside the car. The suspended pull device also allows personnel to directly and intuitively identify how to operate the ceiling hatch to further open it, which is particularly advantageous when considering the foreseeable pressure conditions during evacuation.

[0033] In another embodiment of the elevator car, the enclosure includes locks accessible from both the interior space and the car top. This allows the enclosure to be operated via the same lock for both evacuation by personnel standing on the car top and self-evacuation as required by the fire-fighting elevator car. Specifically, this lock and the emergency unlocking device for one or more landing doors are configured to be operated with the same key. Emergency unlocking devices for landing doors are mostly standardized, and the corresponding keys, such as triangular keys, are carried by firefighters or maintenance personnel, while ordinary users of the elevator equipment do not possess such keys. Therefore, by using a key with an emergency unlocking device for the locks on the ceiling hatches, it is possible to ensure that evacuation personnel are highly likely to carry the correct key, while simultaneously preventing misuse of the hatches and landing doors.

[0034] The object of the present invention is also achieved by an elevator device comprising: at least one vertically extending elevator shaft with multiple stop doors, and the aforementioned car. With this elevator device, the aforementioned advantages regarding the car can be achieved in a corresponding manner.

[0035] The present invention further achieves its objective through a method for evacuating personnel from the aforementioned elevator car. This method comprises the following steps: stepping onto the car top from an upper stop position, opening the car top hatch, opening a flap from a closed position to a limited open position restricted by a retaining device, releasing the retaining device by means of a pulling device and opening the flap from the limited open position to the fully open position, and evacuating personnel through a passageway. Advantageously, all the necessary means for this method are already provided within the aforementioned elevator car without adversely affecting the car's usability, and the method can be advantageously performed simply, safely, and particularly intuitively.

[0036] The present invention further achieves its objective through a method for self-evacuation from the aforementioned elevator car within the aforementioned elevator equipment. This method comprises the following steps: opening a flap from a closed position to a limited open position restricted by a retaining device; releasing the retaining device by means of a pulling device and opening the flap from the limited open position to the fully open position; opening the car top hatch; and evacuating personnel through the passageway. Advantageously, the aforementioned elevator car provides all the necessary means for these methods without adversely affecting the car's availability, and the method can be advantageously performed simply, safely, and particularly intuitively.

[0037] A particular advantage of these methods is that both methods can be implemented using the same means. Preferably, the order of the method steps can be changed unless a specific order is explicitly required technically. However, the order of the method steps described above is particularly preferred.

[0041] Detailed design scheme

[0042] The illustrated embodiments are merely examples and can be modified and / or supplemented in various ways within the framework of the protection defined by the claims. Each feature illustrated for a particular embodiment can be used independently or in combination with other features in any other embodiment. Each feature illustrated for an embodiment of a particular class of claims can also be used accordingly in embodiments of another class of claims.

[0043] Figures 1 and 2 show a car 1 with an interior space 2. In Figure 1, the car 1 is shown without a car door, allowing the interior space 2 to be clearly seen. The interior space 2 is limited in the upper direction O by a walkable car roof 3, which has a car roof hatch 4 that can be closed by means of a flap 4.1 shown in the open position. A guardrail 5 is also provided on the car roof 3 to provide fall protection when walking on it. In Figure 2, the car 1 is shown in an elevator shaft 6, which has a stop position 7 with a stop door (not shown but actually present). This illustrates a malfunction where the car 1 malfunctions below the stop position 7 and cannot move within the elevator shaft 6. The elevator shaft 6 and the car 1 together constitute the elevator equipment 1.1.

[0044] Figures 1 and 2 also show two usage positions of the retractable ladder 8. Figure 1 shows the first usage position, where the ladder 8 is positioned between the floor plate 9 of the interior space 2 and the car top hatch 4, allowing personnel to access the car top 3 from the interior space 2 using the ladder 8. Figure 2 shows the second usage position, where the ladder 8 is positioned between the car top 3 and the stop position 7, allowing personnel to access the stop position 7 from the car top 3 using the ladder 8. In the first usage position, the ladder 8 is substantially extended, i.e., extended; in the second usage position, the ladder 8 is substantially retracted, i.e., retracted. Depending on the distance between the car top 3 and the stop position 7, the ladder 8 can also be partially or fully extended in the second usage position.

[0045] Figure 3 shows from above the ladder 8 in its stored position when the car top hatch 4 is open. Here, the car 1 has a suspended ceiling 10 within the interior space 2, which has a suspended ceiling hatch 11, which can be closed by means of a flap 11.1. The flap 11.1 can be opened in the downward direction U. The car top hatch 4 and the suspended ceiling hatch 11 together form a passage between the interior space 2 and the walkable car top 3. The ladder 8 is positioned in its stored position between the car top 3 and the suspended ceiling 10 and is in a fully compressed state.

[0046] At the first fixing point 12.1, shown in Figures 3 and also in Figures 4 and 5 as the storage position of the ladder 8, the uppermost rung 13 of the ladder 8 is embedded in the receiving portion 14 and held in the receiving portion 14 by means of a retaining device 15.1 configured as a releasable ring. Here, the receiving portion 14 is fixed to the car top 3. The ladder 8 is thus releasably and rotatably held in the receiving portion 14. At the second fixing point 12.2, shown in Figures 3 to 5 as the storage position of the ladder 8, the ladder 8 is held on the car top 3 by means of the bottom rung 16 by means of the retaining device 15.2 configured as a releasable ring. Figures 3 to 5 also show a retaining device 15.3 configured as a releasable ring, by means of which the rung 17 of the ladder 8 is held relative to the uppermost rung 13. Therefore, the unfoldable length of ladder 8 is limited, specifically corresponding to the height difference between the base plate 9 and the car top 3.

[0047] Figure 3 shows the closed position of the flap 11.1, while Figures 4 and 5 show the limited open position of the flap 11.1, which is shown in a simplified manner thereon. The flap 11.1 is pivotally held on the ceiling 10 on the first side 18.1 by means of a hinge 19. A closing device 20 is provided on the second side 18.2, by means of which the flap 11.1 can be held on the ceiling 10. In the limited open position, the flap 11.1 is limited to its opening angle Ω by means of a retaining device 21 configured as a ring. Here, the retaining device 21 is held between a first receiving portion 22.1, which is assigned to the flap 11.1 and formed as a slit, and a second receiving portion 22.2, which is assigned to the ceiling 10 and formed as a slit.

[0048] In the embodiment shown in Figures 4 and 5, the retaining device 21 is formed by a first partial loop 21.1 and a second partial loop 21.2, which act together in the first region 23.1 and the second region 23.2, respectively, for example by means of Velcro fasteners. A first pulling device 24.1 and a second pulling device 24.2 are also formed on the retaining device 21 via the partial loops 21.1 and 21.2. The first pulling device 24.1 is readily accessible from the car top or car top hatch 4 and is specifically designed to be grasped in the closed position of the flap 11.1 and held when the flap 11.1 is opened toward the limited open position. Alternatively, the first pulling device 24.1 can also be held in the position shown in Figure 4 on the ladder 8 or the ceiling hatch 11. The second pulling device 24.2 can be accessed from the opening angle Ω and thereby from the interior space 2. The second pulling device 24.2 is also formed as a fixing member and is wrapped around the first receiving portion 22.1 for this purpose, so that the retaining device 21 does not slide on the receiving portions 22.1, 22.2, and ensures that the allocation of the pulling devices 24.1, 24.2 to the car roof 3 and the interior space 2 is safely maintained.

[0049] Figure 6 illustrates an alternative embodiment of the retaining device 21, wherein the retaining device 21 is formed from a single strip that itself forms a loop. For this purpose, the strip has a first region 23.1 and a second region 23.2, which respectively have corresponding components of a Velcro fastener or constitute such components and act together. The first region 23.1 is formed at one end of the retaining device 21, wherein a portion of the retaining device 21 extends beyond the second region 23.2 and forms a first pulling device 24.1. The first pulling device 24.1 is located on the flap 11.1 when it is in the closed position and is configured to be engaged in the closed position of the flap 11.1 and held when the flap 11.1 is opened toward a limited open position. If the flap 11.1 is opened from the interior space 2 and is not held on the car top side, the first pulling device 24.1 falls into the interior space 2, from which the retaining device 21 can then be released.

[0050] Figure 7 schematically illustrates a method 30 for evacuating personnel from the car 1 in elevator equipment 1.1, as shown in Figures 1 to 5. In the first step 31, the personnel performing the evacuation step onto the car top 3 from the stop position 7 located above the car 1. In the second step 32, the personnel open the car top hatch 4 or the flap 4.1. In the third step 33, the personnel open the ceiling hatch 11 or open the flap 11.1 from the closed position to a limited open position restricted by the retaining device 21. In the fourth step 34, the personnel release the retaining device 21 by means of the pulling devices 24.1, 24.2 and open the ceiling hatch 11 or open the flap 11.1 from the limited open position to the fully open position. In the final fifth step 35, the personnel are evacuated through the passageway.

[0051] Figure 8 schematically illustrates a method 40 for self-evacuation from the car 1 according to Figures 1 to 5 in elevator equipment 1.1. In the first step 41, the ceiling hatch 11 is opened or the flap 11.1 is opened from the closed position to a limited opening position restricted by the retaining device 21. In the second step 42, the retaining device 21 is released by means of the pulling devices 24.1, 24.2, and the ceiling hatch 11 or the flap 11.1 is opened from the limited opening position to the fully open position. In the third step 43, the car top hatch 4 or the flap 4.1 is opened. In the final fourth step 44, personnel self-evacuate through the passageway.
