Description

[Technical field]

[0001] The present invention relates to an elevator car for a passenger elevator, which in particular should be optimized for use by wheelchair users. [Background technology]

[0002] EP 1591401 discloses a typical elevator car. The elevator car is configured as a cuboid on a rectangular base. There is only one door at the front. The car is supported by a car frame that surrounds both side walls. The car frame itself supports a cross beam that extends across the car roof. The car roof is further provided with rollers and corresponding roller support beams. This car structure is certainly suitable for a typical elevator shaft, but it presupposes a large shaft size and relies on costly and heavy drive units, usually above the shaft, for the roller drive. The presence of the frame members makes it impossible to access the elevator in these areas. The object of the present invention is to provide an elevator and a corresponding car that are clearly more compact and scalable, and that also allow access from several sides.

[0003] EP 2516314 discloses a further elevator car. This document discloses a car with a cuboid shape on a rectangular base, which appears to be stabilized by its rectangular floor frame and the corresponding roof frame. The car door is guided at the top in a door guide rail and supported at the bottom by a car door sill. This arrangement appears to enable the door to be guided reliably. It is also typical for many cars. However, both the door guide rail and the car door sill clearly protrude to the left and right beyond the car (i.e. in the direction of door opening). A large-scale designed elevator shaft is therefore required. Such a solution does not seem very suitable for retrofitting a disabled elevator. In any case it requires a very large amount of space.

[0004] JP 2006-151625 A discloses an elevator with a compact guide and drive unit. The elevator has a car on a square base. The elevator shaft is also square. Guide elements are provided on the left and right of the car. Further drive and guide elements are provided at the rear of the car. This also includes a counterweight, which is guided on the rear wall of the elevator shaft. The design appears to be space-saving overall. However, the dimensions of the shaft required are clearly larger than those of the car. In the front area of ​​the shaft, an access door is also provided, and only in this area are there no technical components for drive and guide. At the rear, the shaft must be significantly larger than the car, and large free areas are provided in the shaft on both sides of the car as well. The present invention aims to provide an elevator that is particularly suitable for wheelchair users, but also a clearly more compact elevator. This is already taken into account in the design of the car.

[0005] Elevators, especially passenger elevators as in the cited prior art, serve in many places to improve convenience and thus typically avoid climbing stairs. However, for disabled people, and especially for wheelchair users, it is not comfort that is important, but the ability to overcome heights. In this respect, wheelchair-adapted elevators play a major role and there is a significant demand for them. In many cases, this demand is also limited to be met by limited financial resources. There is therefore a continuing interest in finding particularly efficient and cost-effective elevator solutions that are highly suitable for wheelchair users.

[0006] In this connection, it should be taken into account that rectangular or square elevator shafts are also generally provided for architectural purposes. However, rectangular elevator shafts are not particularly advantageous for wheelchair users. Usually, a wheelchair user should be able to rotate around its long axis, for example to enter in one direction and, after a 180° rotation, exit in the opposite direction. For this purpose, there is no advantage in a rectangular elevator car being longer along one axis. For example, how easily it is possible to rotate around its axis is determined only by the direction in which it extends shorter, while the area available in the other direction is not useful, as its maneuverability remains too limited, even in terms of being able to accommodate, for example, two wheelchairs one after the other.

[0007] This problem is solved by an elevator car according to claim 1. Further advantageous configurations are given in the dependent claims. The advantages are also achieved by a passenger elevator according to claim 12 and by the dependent claims assigned thereto.

[0008] More detailed explanation An elevator car according to the invention has a floor, at least one wall member, an access opening and a car door capable of closing said access opening (and usually further members).

[0009] The floor may comprise an upper floor (which supports the passengers and on which they normally walk) and additionally a supporting floor member arranged below it, where, within the framework of the present invention, this floor should include the entire area bounded by the outer surfaces of the side walls and the outer surfaces of the car doors.

[0010] The elevator car should be fitted into a rectangular shaft and accordingly have wall members disposed along the edges of the rectangle. The elevator car should have at least one access opening, which may occupy a portion of a side of such rectangle or the entire length of such a side. The access opening should be capable of being closed by a car door.

[0011] The floor is bounded by a plurality of edges, where the floor's geometry is such that four of the bounded edges lie along a rectangle and the remaining edges lie within the plane of the rectangle, such that the floor forms at least two obtuse corners in the area of ​​the remaining edges, a first obtuse corner and a second obtuse corner. (If the floor includes door thresholds, these are considered part of the floor herein and should therefore lie within the rectangle.)

[0012] Thus, a suitable floor can be divided into six edges: four of them are located along the sides of the rectangle, and two of them are located opposite each other, bridging the corners of the rectangle.

[0013] It is also expedient if the floor is bounded by eight edges, four of which are arranged along the sides of the rectangle and the remaining edges each bridge the corners of the rectangle. In this case, it is expedient if the four longest edges are arranged along the sides of the rectangle. It is likewise expedient if the remaining edges, which face each other, are of equal length. In this case, it may be expedient if one pair of edges is longer than the other pair of edges. The longer pair of edges then forms obtuse corners, i.e. the first obtuse corner and the second obtuse corner.

[0014] The car door should move between an open position, where entry to the elevator car is possible, and a closed position. In the closed position, access to the elevator car is blocked. From the open position, the car door moves to close along a closing direction. Usually, the car is closed with a lateral displacement in the closing direction. The car door should be formed as a sliding door with a first panel and a second panel. Here, the first panel should be a "fast" panel, meaning that the first panel moves past the second panel in the closing direction. The first panel should have a leading edge facing the closing direction and a trailing edge facing the opposite side, and the second panel should also have a leading edge facing the closing direction and a trailing edge facing the opposite side. The second panel is preferably adjacent to the first obtuse corner when the car door is closed.

[0015] According to the invention, when the elevator car is opened, at least the trailing edge of the first panel should not be above the floor of the elevator car, which means that the space outside the elevator car is also used for the movement of at least one panel of the car door.

[0016] It is also expedient that when the car doors are open, the rear edge of the second panel is not above the elevator floor, so that both the first car door panel and the second car door panel can move, either totally or partially, at least with their rear edges beyond the elevator car floor and protrude therefrom.

[0017] Both the first and second panels have a leading edge facing the closing direction, a trailing edge on the opposite side and a vertical central axis centered between said edges. It is entirely expedient that, when the car doors are open, not only the trailing edges but even the central axes of the panels are not above the elevator floor.

[0018] At the same time, the rear edge of the first panel (and preferably also the rear edge of the second panel) should remain within the above-mentioned rectangle defined by the car when the car is open. This car configuration saves space and allows a compact shaft to be provided. The corresponding elevator can therefore also be fitted and retrofitted in places where there is no space in conventional elevator designs, especially in conventional elevator designs with car doors.

[0019] Although this selected shape of the elevator car with two obtuse corners is very advantageous for the construction of space-saving elevators for wheelchair users, this shape has certain drawbacks for the arrangement of important components, in particular the operating components, but also for the arrangement of the doors, which are overcome within the framework of the present invention.

[0020] It is expedient to arrange the operating element in the region of the first obtuse corner or in the region of the second obtuse corner. Such operating elements are in particular elements by which the desired floor can be entered in the transport. It is particularly expedient to provide operating elements with the same effect above and below, i.e. at a first level for standing persons and at a (lower) second level for wheelchair users.

[0021] It is also expedient if the car doors have three panels, which can be opened in two directions, such that the first and second panels have a first opening direction and the third panel has an opening direction facing in the opposite direction, for example the first and second panels can be opened to the right and the right panel can be opened to the left.

[0022] It is particularly advantageous here if the third panel is designed to be shorter than the first and second panels, since it cannot open towards the obtuse corner and therefore takes up less space than the first and second panels.

[0023] It is also expedient if the car door has four panels, and the car door can be opened in two directions, such that the first and second panels have a first opening direction and the third and fourth panels have an opening direction facing in the opposite direction.

[0024] An appropriate elevator car can have two guide noses, which can be appropriately connected to the guide rails. Although more than two guide noses and correspondingly more than three guide rails can also be employed, within the scope of the present invention, it is usually sufficient for the elevator car to have two guide noses. For this purpose, the first guide nose can be arranged in a first obtuse corner and the second guide nose in a second obtuse corner. The advantage of using an obtuse corner for arranging the guide nose is that a relatively short diagonal is obtained for better guiding. The term "guide nose" here generally refers to a member, usually a mechanical member, suitable for interacting with the guide rail, but can also be implemented as a female or male member (the guide nose is often also simply called a "guide part"). For example, the guide nose can be formed in the form of a groove surrounding the guide rail. It also makes sense to use four guide noses, specifically at different heights of the car, for example two near the roof and two near the floor (i.e. the top or bottom 10% of the car height).

[0025] It has proven expedient if, when the car door is opened, at least the rear edge of the first panel is displaced behind the first guide nose; that is, more precisely, when the panel is moved in the opening direction (i.e. opposite to the closing direction), the rear edge of the panel is moved beyond the projection of the guide nose to the inside of the door. In this way, a kind of sandwich is formed, i.e. the guide nose is trapped between the car door and the elevator car, in particular between the floor of the elevator car. This arrangement therefore allows the guide rail to be particularly close to the car and at the same time the remaining space can be used for the movement of the car door.

[0026] In this context, it is expedient if at least a first panel of the car door has an inner side and an outer side, which when the car door is in the closed position faces towards the inside of the car and when the car door is in the open position faces towards the first guide nose. The second panel can be provided in a similar manner. It is therefore also expedient if when the car door is in the open position the first guide nose is located between the inner side of the first panel and the floor of the elevator car.

[0027] This can also be provided for the second guide nose arranged in the second obtuse corner.

[0028] The elevator car configuration is suitable for providing multiple access openings. For example, a first access opening and a second access opening on the opposite side can be provided. The first access opening and the second access opening can also be provided at right angles to each other. This basic geometry of the elevator car allows access openings and corresponding car doors to be provided in four directions. In conventional elevator cars, it is usually necessary to provide a significant portion of at least one side wall for operating elements and other devices. Within the scope of the present invention, such operating elements can be provided in the first obtuse corner or alternatively or additionally in the second obtuse corner, so that all side walls of the elevator car are available for access openings and car doors.

[0029] It is also expedient for an elevator car to have two car doors and for each car core to have two panels, where each car door is expediently adjacent to an obtuse corner with its later panel, in this case, so that the space available in the obtuse corner can be utilized for the two car doors.

[0030] Within the scope of the present invention, it is also of interest to make available a passenger elevator with an elevator car, which preferably has the features already mentioned, individually or in combination.

[0031] The elevator is a passenger elevator with an elevator car, the passenger elevator having an elevator shaft with a substantially rectangular bottom surface, above which four shaft walls are resting, the shaft walls forming four shaft corners, the elevator car having four side walls extending substantially parallel to the four shaft walls, the elevator car being spaced apart from adjacent shaft corners in the region of a first corner, the elevator car having a car door, the car door comprising a first panel and a second panel. In a passenger elevator, the first panel is formed as a sliding door with a first panel having a leading edge facing the closing direction, a trailing edge on an opposite side thereof, and a vertical central axis centered between the edges, and the second panel has a leading edge facing the closing direction, a trailing edge on an opposite side thereof, and a central axis centered between the edges, the first panel moving past the second panel in the closing direction, the second panel adjacent the first obtuse corner when the car doors are closed, characterized in that the central axis of the first panel projects beyond the elevator car when the car doors are open.

[0032] Also expedient is a passenger elevator in which a first guide rail is provided in one shaft corner and a second guide rail is provided in the opposite shaft corner, so that when the car doors are opened, at least the rear edge of the first panel is displaced in the area between the first guide rail and the adjacent shaft corner.

[0033] Further features and advantages of the present invention are apparent from the following drawings and the associated description. In the drawings and the associated description, the features of the present invention are described in combination. However, these features may also be included in other combinations of the subject matter according to the present invention. Therefore, each disclosed feature should also be considered as being disclosed in a technically meaningful combination with other features. Some figures are somewhat simplified and schematic. [Brief description of the drawings]

[0034] [Figure 1] 1 is a cross-sectional view (plan view) of an elevator car according to the present invention. [Diagram 2] FIG. 2 is a view corresponding to FIG. 1, showing the car in plan view together with the surrounding elevator shaft; [Diagram 3] FIG. 2 shows a car in an elevator shaft with the doors open. [Figure 4] FIG. 2 is an enlarged cross-sectional view of a corner region of the car and elevator shaft. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0035] 1 is a cross-sectional view of car 10. This is a horizontal section, looking from above down at floor 12 of car 10, and therefore may generally be referred to as a plan view.

[0036] The floor of the car supports the passengers and possibly the baggage. Unlike common simple elevators, especially retrofit elevators that offer the possibility of accessing wheelchair users in a small space, the car is surrounded on all sides by side walls or car doors. This increases safety and also allows for higher speeds within the framework of current safety regulations.

[0037] The floor 12 extends within a square, but is not a square as the corners of the square are not filled in. The car 10 is bounded by a first side wall 14 and a second side wall 16. The side wall 14 has a first access opening 18 on an opposite side thereof and the second side wall 16 has a second access opening 20 on an opposite side thereof.

[0038] Side walls 14 and 16 extend perpendicular to one another but do not meet. Rather, a first obtuse corner is provided in the area where the extensions of the side walls would intersect. On the opposite side, a second obtuse corner 24 is provided in the area where the directions of the entry openings intersect. A first acute corner 26 is provided between side wall 16 and first entry opening 18. A second acute corner 28 is provided between first side wall 14 and second entry opening 20.

[0039] The operating member 30 can be seen as an important member of the car. Typically, there may be two operating members, one adapted to the standing height of the user and one adapted to a suitable operating height for a wheelchair user. Between the first and second side walls 16, a wall member 32 is provided. When viewed from above, there is an obtuse corner between the side walls, and from the user's inside perspective, simply a further wall member 32 or panel is visible.

[0040] Obtuse corners are called obtuse corners because the wall panel in the corner, which is visible to the user, is clearly shorter than the adjacent side wall. Within the scope of the present invention, it is generally expedient, for example, for the width of the wall panel bridging the corner of the car to be no more than 50%, for example no more than 40% or 30% of the width of the adjacent shorter side wall.

[0041] A wall element 34 is correspondingly arranged in the second obtuse corner 24. It is expedient if this can carry the actuating element 30. However, it is also possible to provide a separate holding part for the actuating element 30, possibly independent of the wall element 34.

[0042] In the abovementioned acute corners, wall elements are also provided. In the first acute corner 26, this is the wall element 36, in the second acute corner 28, this is the wall element 38. It is expedient for the wall elements in the acute corners to have a smaller width than the wall elements in the obtuse corners. Within the scope of the present invention, it is generally expedient, for example, for the width of such a wall element in an acute corner to be less than 80%, or less than 50%, or even less than 30% of the width of the wall element in the obtuse corner.

[0043] The first access opening 18 is closed by a first car door 40. The first car door 40 consists of two panels, a first panel 42 and a second panel 44. The car door opens towards the second obtuse corner 24. That is, the first panel 42 travels a further distance when opening than the second panel 44. Therefore, the first panel 42 is usually referred to as the "fast" panel.

[0044] The second access opening 20 is closed by a second car door 46. This car door has three panels. The car door 46 comprises a third panel 48 and a fourth panel 50. This door further comprises a fifth panel 52. The panels 48, 50 also open towards the second obtuse corner 24. Thus, in this case, the fourth panel 50 is the fast panel. The fifth panel 52 opens in the opposite direction, i.e. towards the second acute corner 28. The fifth panel 52 is substantially shorter than the third panel 48 and the fourth panel 50.

[0045] In general, within the scope of the present invention, it is expedient to employ a car door having three panels, of which the width of the third panel is less than half or even one third of the width of the widest of the other two panels.

[0046] Figure 2 is a view corresponding to Figure 1, but showing the elevator car 10 installed in an elevator shaft. For clarity, only the essential parts of the car 10 are shown, which again consist of the floor 12 and further of the first car door 40 and the second car door 46.

[0047] The car 10 is bounded by a first shaft wall 54 and a second shaft wall 56. On the opposite side of the first shaft wall 54 is a third shaft wall 58 and a first shaft door 60, and on the opposite side of the second shaft wall 56 is a fourth shaft wall 62 and an adjacent second shaft door 64. Although the elevator car is suitable for various types of shafts, a shaft constructed with corner posts is shown here, these being shaft corner posts 66A, 66B, 66C and 66D. These corner posts are located at the corners of a square, so that the shaft has a square base. However, as mentioned above, the floor 12 is not square, but rather is spaced from the corners of the shaft, just in the corner areas.

[0048] At the obtuse corners of the car 10, therefore, there is space for the installation of further equipment in the shaft. In this case, a first guide pillar 70 is provided, which is connected to the corner pillar 66D by a first connecting member 68. On the opposite side, a guide pillar 72 is provided, which is connected to the corner pillar 66B by a connecting member 74. Each guide pillar provides (in the context of the present invention generally) at least one guide rail. These guide pillars can consist only of guide rails (for example flat bars) or can be shaped as further elements, for example T-beams. The guide pillars are therefore often simply referred to as guide rails. However, it is advantageous if the guide pillars are self-supporting elements, which at least do not require support by the shaft wall, and even if the guide pillars are supported on the shaft floor, they do not need support by the shaft wall.

[0049] Figure 3 is a view of the elevator shaft surrounding the elevator shaft from a selected viewing direction in Figure 2. While the car in Figure 2 is shown with closed car doors, in Figure 3 the car doors are shown open, and to simplify the illustration the shaft doors, which would normally also be provided, have been omitted.

[0050] This first access opening 18 is opened for access by displacing the panels of the first car door, i.e. the first panel 42 and the second panel 44, towards the second obtuse corner 24, where the first panel 42 covers the second panel 44. The first panel 42 is on the outer shaft wall side, whereas the second panel 44 is on the inner car side. As can be seen, in the open or unfolded position, the panels utilise the free space that arises between the car and the shaft wall (here, in particular the third shaft wall 58). The panels 42, 44 are therefore displaced into the area behind the wall element 34. Apart from that, they are also displaced out of the area of ​​the car floor 12. They therefore utilise an area that is on the outside of the car but does not extend deep into the shaft.

[0051] A corresponding solution also occurs in the region of the second access opening 20. In this case, the third panel 48 and the fourth panel 50 are displaced into the region of the second obtuse corner 24, so that the second access opening 20 is freed. These panels also utilise the free space behind the wall element 34 and are displaced with their inner side facing towards the guide post 70.

[0052] The free space in the second obtuse corner 24 is utilized by both car components and elevator installation components. The car components of concern here are the car door panels and the operating members 30. Further components necessary for the technical operation of the elevator are the guide posts 70 and the corresponding connecting members 68.

[0053] Moreover, this double utilization is even more efficient in practice: the door panel is displaced into the aforementioned free space so that the guide post 70 is on the inside of the door panel (i.e., on the side facing the car).

[0054] The fifth panel 52 of the door is displaced into the area of ​​the second acute corner 28. At this point, this fifth panel is behind the wall element 38. Thus, even in the area of ​​the acute corner, the free space between the car and the shaft can be utilized for door panels, which can then be moved in an advantageous manner into the open position and the second access opening can be opened as completely as possible. It would also be conceivable that not only the door panels of the car utilize the free space in the obtuse corner, but also further devices of the car (such as, for example, further operating elements) or further devices of the shaft utilize the free space in the obtuse corner. What is considered in this respect would be that further guide rods could also be fitted in the area of ​​the acute corner, or for example a shaft copy system, which allows the car height to be determined.

[0055] FIG. 4 shows an enlarged cross section of the shaft structure in the region of the corner pillar 66D. Such a corner pillar can be shaped as a profiled pillar, so that the corresponding shaft walls, for example the third shaft wall 58 and the fourth shaft wall 62, are well connected to the corner pillar 66D and are supported by these corner pillars. The corresponding walls can be well manufactured from metal, for example aluminum, from plastic or from glass. They can be provided with a suitable frame. They can also be provided with grooves for suitable connections. In shaft pillars with a substantially square profile, suitable connecting members bend at right angles.

[0056] Between these connecting elements, additional connecting elements can be provided, for example at an angle of 45 degrees. These additional connecting elements serve to connect the shafts with technical components. For example, here a groove is provided (not described in more detail) bent at an angle of 45 degrees, which receives a connecting element 68. This connecting element 68 carries a guide post 70.

[0057] This close-up view highlights how the arrangement of the corner posts and guide posts creates an area where the door panel can move to the open position, shown cross-hatched as area 76.

[0058] Overall, it can be seen how an elevator car and corresponding passenger elevator that offers many benefits to wheelchair users can be constructed in a cost-effective and efficient manner. [Explanation of symbols]
