[0003] Management system

[0004] The present invention relates to a guidance system for a carriage of an elevator, and a carriage comprising such a guidance system.

[0005] In an elevator, a cabin is typically transported vertically along a track between different floors or levels within a building. At least in tall buildings, the most common elevator type uses a system where the cabin is held by rope- or belt-like suspension elements and moved within an elevator shaft by a drive mechanism. To at least partially counteract the load of the elevator cabin being moved by the drive, a counterweight is usually attached to the opposite end of the suspension elements. This counterweight has at least the same mass as the elevator cabin. As a rule, the mass of the counterweight exceeds that of the elevator cabin by half the maximum permissible payload. Depending on the elevator type, an elevator system may also include multiple counterweights and / or multiple elevator cabins.

[0006] The car and counterweight both fall under the term "carriage." Elevator carriages are typically guided along guide rails and are equipped with guide shoes. These guide shoes are typically attached directly to a catch frame of the carriage, which has an upper yoke, a lower yoke, and two lateral supports. Guide shoes guide the carriage along a guide rail via sliding elements or rollers. This movement of the carriage can generate noise, which can travel along the guide rail and through the rail's fixings into the building. There, the noise can be perceived as unpleasant by the occupants. Furthermore, the noise can also be perceived as unpleasant inside the car. Guide shoes typically grip a rail on three sides.

[0007] The rollers of the guide shoes, if present, are typically made of hard plastic to ensure a long service life and to prevent plastic deformation and the resulting out-of-roundness after prolonged static loading. For space reasons, the rollers often have a small diameter and therefore usually exhibit high rigidity. 2024P00172WÖ

[0008] - 2 -

[0009] Furthermore, it is important to guide the vehicle safely along its path so that it does not collide with objects along the route. This could damage these objects or the vehicle itself.

[0010] Guide shoes in which individual rollers are spring-mounted on a guide shoe housing are known. KR 102599429 Bl shows a guide shoe in which one of the rollers is spring-mounted with a disc spring. US 6345698 Bl shows a guide shoe in which two of the three rollers of the guide shoe are spring-mounted.

[0011] Application EP 2 872 431 Bl shows a guide shoe typically used to guide trolleys. The guide shoe has rollers, each individually mounted. When the trolley traverses small irregularities on the guide rail, such as those occurring at rail joints, and due to inaccuracies in the rail installation, relatively large contact forces are briefly exerted on the rollers, resulting in relatively loud noises.

[0012] Therefore, one task can be seen as reducing the steering noise that affects passengers in the cabin and residents of the steering noise area.

[0013] According to a first aspect of the invention, a guide system for guiding a carriage of an elevator along a guide rail solves the problem. The guide system comprises a guide shoe for guiding the carriage along a guide rail, a first leaf spring, and a leaf spring bearing suitable for being attached to a carriage of the elevator. A first end of the first leaf spring is connected to the guide shoe, and a second end of the first leaf spring is connected to the leaf spring bearing.

[0014] According to a second aspect of the invention, a carriage of an elevator comprising a guide system according to the first aspect of the invention solves the problem. The leaf spring bearing is connected to the carriage.

[0015] Possible features and advantages of embodiments of the invention can be considered, among other things and without limiting the invention, as being based on the ideas and findings described below. 2024P00172WÖ

[0016] - 3 -

[0017] A leaf spring has an elongated, essentially beam-shaped form with at least two ends. The leaf spring can be straight, i.e., primarily cuboid, or it can be curved along its length. In particular, the length of the leaf spring, measured along its length, can be greater than (or equal to) the distance between its two ends. The length of the leaf spring can be greater, preferably more than three times greater, than its width. Furthermore, the width of the leaf spring can be greater, preferably more than seven times greater, than its thickness. The leaf spring is preferably made of a resilient material such as metal, plastic, and / or composite materials.

[0018] The leaf spring of the guide system has the advantage that the entire guide shoe is slidably mounted on the cabin. This slidability allows the contact forces on the guide shoe to be reduced, thereby also reducing guide noise. Such a guide shoe could, for example, be the guide shoe from EP 2 872 431 B 1.

[0019] The guide shoe is preferably designed to engage three surfaces of a guide rail. Preferably, the guide shoe has at least one sliding surface or roller for each of these three surfaces of the guide rail.

[0020] The leaf spring is connected to the leaf spring bearing or guide shoe using known connection techniques. The connection can therefore be, in particular, a bolted connection. For this purpose, the leaf spring is preferably pressed against the guide shoe or leaf spring bearing by means of one or more bolts. These bolts can pass through the leaf spring bearing or guide shoe and be secured on the opposite side with a nut, or the bolts can be screwed directly into the leaf spring bearing or guide shoe. Preferably, a clamping plate is positioned between the bolt head or nut and the leaf spring. An edge of this clamping plate can then define which part of the leaf spring provides the suspension and which part of the leaf spring is clamped and thus firmly connected.

[0021] Other possible joining techniques include soldering, welding, or riveting. Joining firmly connects the components to prevent relative displacement at the joints under the forces occurring during operation. 2024P00172WÖ

[0022] - 4 -

[0023] Preferably, the leaf spring bearing is rigidly connected to the chassis's safety frame. A safety frame is a rigid structure of the chassis that typically comprises an upper yoke, a lower yoke, and two lateral supports. The primary function of the safety frame is to transfer the forces of the load—that is, the weights in a counterweight or the cabin body and its contents in the case of a cabin—to a load-bearing element, a safety device, or a buffer plate. For this purpose, the safety frame is designed to be robust.

[0024] According to a preferred embodiment, the guide system has a second leaf spring. A first end of the second leaf spring is rigidly connected to the guide shoe, and a second end of the second leaf spring is rigidly connected to the leaf spring bearing.

[0025] A second leaf spring allows for a significantly more stable construction. The movement of the guide shoe can also be guided more precisely in a specific direction.

[0026] According to a preferred embodiment, the first leaf spring and, in particular, the second leaf spring are essentially flat.

[0027] A flat leaf spring is essentially flat in its installed or undeformed position. This primarily means that during manufacturing, a flat piece of sheet metal in the area serving as the spring is essentially neither bent nor folded. Small bends at the end of the spring, which serve to align the spring during assembly, do not contradict the definition of a flat leaf spring. If the guide system has two leaf springs, preferably both leaf springs are flat.

[0028] According to a preferred embodiment, a leaf spring direction is defined on the guide system. The first leaf spring is aligned along the leaf spring direction from its first end to its second end. In particular, the second leaf spring is also aligned along the leaf spring direction from its first end to its second end. Furthermore, a guide direction for the guide system is defined. The guide system is movable along the guide rail in this guide direction. The leaf spring direction is perpendicular to the guide direction.

[0029] Due to the arrangement of the leaf springs perpendicular to the guide direction, the leaf springs are positioned horizontally in the elevator system. This allows the leaf springs to be used in a constructive manner (2024P00172WÖ).

[0030] - 5 - advantageously, and in particular in a space-saving manner, arrange them along an upper yoke or a lower yoke of the cabin.

[0031] According to a preferred embodiment, the first leaf spring and the second leaf spring are aligned parallel to each other.

[0032] Preferably, the first leaf spring and the second leaf spring are also arranged perpendicular to the guide direction. Such an arrangement results in a particularly advantageous spring characteristic. In a direction parallel to the leaf spring direction, the guide shoe is essentially inelastic, while in a direction perpendicular to both the leaf spring direction and the guide direction, the guide shoe can be held relatively flexibly, i.e., with the spring stiffness determined by the leaf spring.

[0033] Because the leaf springs are flat and aligned parallel to each other, this results in a particularly advantageous spring characteristic. The use of two leaf springs effectively prevents the guide shoe from twisting around an axis parallel to the guiding direction.

[0034] According to a preferred embodiment, the length of the first leaf spring, measured from the first end of the first leaf spring to the second end of the first leaf spring, is longer than the longest length of the guide shoe. In particular, the guide shoe can fit inside a cube whose edge length is equal to the longest length of the guide shoe.

[0035] The longest length of the guide shoe is one of its characteristic lengths. Such a characteristic length could be, for example, the length, depth, or width of the guide shoe, and especially of a guide shoe housing or frame. It could also be the length of a sliding surface, a sliding element, or the diameter of one of the rollers. The guide system thus features a relatively compact guide shoe, which as a whole is elastically mounted via the leaf spring. A long leaf spring allows for soft suspension of the guide shoe.

[0036] According to a preferred embodiment, the guide shoe comprises a guide element and a guide shoe structure. The guide element is suitable for transferring guides directly onto the surface of a guide rail. The guide shoe structure accommodates the guide element. The guide shoe structure is connected to the first leaf spring and, in particular, 2024P00172WÖ

[0037] - 6 - connected to the second leaf spring.

[0038] The guide element can preferably be designed as a guide roller or as a sliding element. Preferably, each guide shoe has three guide elements: one that can transmit forces to the guide rail on the up-side and two guide elements that can transmit forces to the guide rail laterally. The guide structure serves to hold the guide elements relative to each other so that the guide shoe can guide reliably along a guide rail.

[0039] In particular, the guide structure can partially comprise a housing or a guide element carrier for receiving the guide element(s) or a complete commercially available guide shoe. Furthermore, the guide structure can have a mounting point for attaching the leaf spring. Alternatively, the guide structure can integrally include the receptacles for the guide element(s) and the means for attaching the leaf spring.

[0040] According to a preferred embodiment, a shaped element is arranged between the first leaf spring and the second leaf spring to limit the deformation of the first and second leaf springs.

[0041] The molded part is preferably rigidly connected to the leaf spring bearing. It can be attached directly to the leaf spring bearing. Alternatively, it can also be rigidly connected to the guide shoe. In this case, the molded part moves back and forth relative to the vehicle body together with the guide shoe during travel.

[0042] The molded body can, for example, have a first contour against which the first leaf spring conforms during its deformation. As the leaf spring deforms, it increasingly conforms to the contour, thus exhibiting progressive spring stiffness. This allows for a very soft spring stiffness in a central position, while in an outer region, where the vehicle body comes relatively close to the limits of its clearance profile, the spring stiffness and therefore the restoring forces increase significantly.

[0043] According to a preferred embodiment, the guide system further comprises a 2024P00172WÖ

[0044] - 7 -

[0045] The bearing surface for the guide shoe rests against this surface and can slide along it. This can make rotation of the guide shoe more difficult. Rotation of the guide shoe could lead to misalignment of the guide elements on the guide rail. Such misalignment could cause the guide shoe to lock or, due to a stick-slip effect, to vibrations in the guide shoe. Because the bearing surface ensures that the guide shoe is always correctly aligned, smooth movement of the vehicle is enabled.

[0046] The chassis according to the second aspect of the invention preferably comprises four guide systems according to the first aspect of the invention. The guide systems are preferably attached to a catch frame of the chassis. A catch frame typically comprises an upper yoke, a lower yoke, and two lateral supports. Alternatively, it is possible to replace two of the four conventional guide shoes that a chassis usually has with a guide system. The leaf spring bearing serves to attach the guide system to the chassis. Any molded part that may be present can be attached either directly to the leaf spring bearing or to the chassis. Alternatively, the molded part can be attached to the guide shoe.

[0047] According to a preferred embodiment, a bearing surface is provided directly on the chassis. The guide shoe rests against this bearing surface.

[0048] The contact surface can therefore be integrated directly into the chassis. It can be designed as a surface of the upper or lower yoke. Alternatively, the contact surface can be attached separately to the upper or lower yoke. This has the advantage of a simplified chassis design, as the contact surface does not need to be a direct component of the leaf spring bearing, but rather is created during the assembly of the chassis.

[0049] According to a preferred embodiment, a retaining element guides the guide shoe along the support surface.

[0050] The retaining element prevents the guide shoe from moving away from the support surface. This reliably prevents the guide shoe from rotating and, for example, becoming jammed against the guide rail. The retaining element is preferably 2024P00172WÖ.

[0051] - 8 - also generate a braking force between the bearing surface and the guide shoe to dampen the relative movement between the guide shoe and the bearing surface. Such a braking force can be generated, for example, by friction, by pressing the guide shoe against the bearing surface with a normal force. For this purpose, the retaining element can, for example, have a spring that then applies a predefined normal force between the guide shoe and the bearing surface. Furthermore, the bearing surface can, for example, also be coated with a highly viscous fluid to achieve a desired damping characteristic.

[0052] According to a preferred embodiment, the leaf spring bearing is designed as part of the chassis. The leaf spring bearing is designed as an integral component of the chassis. That is, the chassis can be part of the upper yoke.

[0053] According to a preferred embodiment, an emergency guide is provided on the guide shoe of the guide system.

[0054] According to a preferred embodiment, an emergency guidance system is designed on the vehicle body.

[0055] The emergency guidance system for a trolley is designed as a preferably metallic stop, which, in the event of a failure of the guide shoe or the guidance system, prevents a situation in which the trolley derails from the rail system or leaves the clearance gauge and could thereby collide with stationary objects in the shaft. Preferably, the emergency guidance system is located on the trolley's catch frame.

[0056] The emergency guidance system can therefore be designed on the guide shoe and / or on the catch frame of the carriage. Designing it on the guide shoe is particularly advantageous if the guidance system has a molded body.

[0057] Further advantages, features, and details of the invention will become apparent from the following description of exemplary embodiments and from the drawings, in which identical or functionally equivalent elements are provided with identical reference numerals. These show:

[0058] Fig. 1 shows an elevator with the guide system,

[0059] Fig. 2 shows a first embodiment of the guide system, 2024P00172WÖ

[0060] - 9 -

[0061] Fig. 3 is a first schematic representation of the first embodiment of the guide system, Fig. 4 is a schematic representation of a second embodiment of the guide system, Fig. 5 is a schematic representation of a third embodiment of the guide system, Fig. 6 is a schematic representation of a fourth embodiment of the guide system, Fig. 7 is a schematic representation of a fifth embodiment of the guide system.

[0062] Fig. 1 shows an elevator 10. A carriage 20 travels vertically along the guide rails 21. The carriage is supported by a traction element 302, for example, a rope or a belt. The carriage 20 can be moved by means of a drive 301. The carriage 20 can be, for example, a cabin or a counterweight. Conventional elevators have one cabin and one counterweight, i.e., two carriages. A possible second carriage of the elevator 10 is not shown here. The carriage is guided on two guide rails 21 by means of four guide systems 30.

[0063] Fig. 2 shows a (more detailed compared to Fig. 3) representation of a first embodiment of the guide system 30. The chassis 20 has a traction roller 305 over which a traction element can run, from which the chassis 20 can be suspended. Here, the chassis 20 acts as a counterweight; it could also be a cabin. A leaf spring bearing 34 is attached to the chassis 20. One of the two leaf springs 31 and 32 is arranged on each side of the leaf spring bearing 34. The leaf springs 31 and 32 are undeformed. A second end 52 of the first leaf spring 31 is connected to the leaf spring bearing 34. Furthermore, a second end 54 of the second leaf spring 32 is also connected to the leaf spring bearing 34.

[0064] The guide shoe 33 has a first roller 201 and a second roller 202 to transmit forces laterally to a guide rail, and a third roller 203 to transmit forces laterally to a guide rail. These rollers are held together by a guide shoe structure 204. A first end 51 of the first leaf spring 31 and a first end 53 of the second leaf spring 32 are connected to the guide shoe 33, and in particular to the guide shoe structure 204. Because the guide shoe 33 is supported by the two leaf springs 31 and 32, it can slide back and forth along the bearing surface 22. Thus, due to its minimal mass, the guide shoe 33 can follow the irregularities of the guide rail much more easily than if the 2024P00172WÖ

[0065] - 10 - the entire carriage 20 would have to follow the unevenness of the guide rail. The smaller guide rails then also result in less guide rail noise.

[0066] The leaf spring direction 101 of the leaf springs 31 and 32 runs from their respective first ends 51 and 53 to their respective second ends 52 and 54. The guide direction 102 is aligned along the guide rail (not shown). The guide direction is therefore the direction along which the carriage 20 is moved by the drive.

[0067] The length LI of the first leaf spring 31 and the second leaf spring 32 is significantly longer than a characteristic length of the guide shoe L2. The length of the leaf springs 31 and 32 is preferably measured in the direction of the leaf spring direction 101.

[0068] Furthermore, the guidance system features two emergency guides 61 and 62. The first emergency guide 61 is located on the guide shoe of the guidance system. The second emergency guide 62 is located on the carriage. The emergency guides serve to keep the carriage securely within its clearance profile in order to prevent damage to the carriage or in the shaft that would result from a collision.

[0069] Fig. 3 shows essentially the same embodiment of the guide system 30 as already shown in Fig. 2, but the representation is more schematic than in Fig. 2, and the leaf springs 31 and 32 are shown deformed, as could occur when the guide shoe 33 deflects upon traversing an unevenness in the guide rail 21. In particular, the details of the guide shoe 33 and the running body are not shown here. One of the two leaf springs 31 and 32 is arranged on each side of a leaf spring bearing 34. These leaf springs 31 and 32 are essentially flat, so that in an undeformed state (not shown) they would be straight. A second end 52 of the first leaf spring 31 is connected to the leaf spring bearing 34. Furthermore, a second end 54 of the second leaf spring 32 is also connected to the leaf spring bearing 34. A first end 51 of the first leaf spring 31 and a first end 53 of the second leaf spring 32 are connected to the guide shoe 33.The leaf springs 31 and 32 are shown deformed, as they would be when a lateral force is applied to the guide shoe 33. Because the guide shoe 33 is supported by the two leaf springs 31 and 32, it can slide back and forth along the bearing surface 22 when subjected to such a deflection. 2024P00172WÖ.

[0070] - 11 -

[0071] It can also be seen how such a deflection of the guide shoe 33 only leads to a displacement of the guide shoe 33, but not to a rotation of the guide shoe 33. This is an advantage of using two leaf springs.

[0072] Figures 4 to 6 each show, in schematic form, further embodiments of a guide system 30. The leaf spring bearing 34, the guide shoe 33, and the guide rail 21 are shown in their respective positions. The guide rail 21 is depicted in such a way that it is clear where and in which orientation the guide rail 21 is preferably arranged relative to the guide system 30. The guide shoes 33 are shown in an abstract form, so that the details of the interaction between the guide shoe 33 and the guide rail 21, as shown, for example, in Figure 2, are not visible.

[0073] Fig. 4 shows a first leaf spring 31 and a second leaf spring 32, each having a bend 401 at its respective second ends 52 and 54. The bends 401 and 402 facilitate the mounting of the leaf springs 401 and 402 to the leaf spring bearing 34 because they define the position of the leaf springs 401 and 402 relative to the leaf spring bearing 34. The leaf springs 31 and 32 are both essentially flat. Only the bends 401 and 402 at the ends 52 and 54 distinguish the leaf springs 31 and 32 from a completely flat leaf spring, such as those shown in Fig. 3 or Fig. 5. These bends 401 and 402, however, have no effect on the spring characteristics.

[0074] The use of two leaf springs 31 and 32 ensures, as in Figures 2 and 3, that the guide shoe 33, which is attached to the first ends 51 and 53 of the leaf springs 31 and 32, twists as little as possible.

[0075] Fig. 5 shows an embodiment corresponding to that of Fig. 4. However, the leaf springs 31 and 32 here do not have any bends. A first end 51 of the first leaf spring 31 and a first end 53 of the second leaf spring 32 are connected to the guide shoe 33. A second end 52 of the first leaf spring 31 and a second end 54 of the second leaf spring 32 are connected to the leaf spring bearing 34. However, it would also be quite possible to provide bends on the leaf springs 31 and 32 in this embodiment. The leaf springs 31 and 32 are both essentially flat, as in Fig. 4. The embodiment has 2024P00172WÖ

[0076] - 12 - a shaped body 600. If the guide shoe 33 is deflected laterally during travel, the leaf spring 31 conforms to a first contour 601 of the shaped body 600. If the guide shoe 33 is deflected laterally in the opposite direction during travel, the leaf spring 32 conforms to a first contour 602 of the shaped body 600. The design of the contours 601 and 602 can define a relationship between the restoring force and the lateral deflection of the guide shoe 33.

[0077] Fig. 6 shows a guide system 30 that has a curved, i.e., not flat, first leaf spring 31. This leaf spring 31 also has a bend 401 at both its second end 52 and its first end 51. This embodiment is particularly easy to assemble, since all assembly steps can be carried out from the same side. Depending on the type of bend, and in particular the bending radius and the length of the arc, very different spring characteristics can be achieved in one direction of deflection of the guide rail on the guide side, and in a perpendicular direction of lateral deflection.

[0078] Fig. 7 shows a fifth embodiment of the guide system 30 in a side view. In this embodiment, a retaining element 36 guides a guide shoe 33 along the support surface 22. This prevents the guide shoe 33 from lifting off the support surface 22. Furthermore, it also prevents the guide shoe 33 from twisting. The retaining element 36 can be connected to the carriage 20 next to the guide shoe 33, as shown here. However, it can also be connected to the carriage 20, for example, via an elongated hole in the guide shoe 33.

[0079] This embodiment further features a sliding element 37 that can slide along the guide rail 21. The guide shoe structure 204 connects the sliding elements 37 to the first leaf spring (concealed by the first) and the second leaf spring 32. The leaf springs are in turn connected to the leaf spring bearing 34. The leaf spring bearing 34 is rigidly connected to the carriage body 20. Alternatively, a roller guide shoe can be used in this embodiment.

[0080] Fig. 7 also shows an emergency guide 61 which is arranged directly on the guide shoe 33, or rather on the guide shoe structure 204. Furthermore, an emergency guide 62 is arranged directly on the carriage 20. Both emergency guides 61 and 62 are optional. They can be completely omitted. 2024P00172WÖ

[0081] - 13 - can be omitted, each can be attached individually, or both emergency guides 61 and 62 can be attached.

[0082] Finally, it should be noted that terms such as "having," "comprising," etc., do not exclude other elements or steps, and terms such as "a" or "an" do not exclude a plurality. Furthermore, it should be noted that features or steps described with reference to one of the above embodiments may also be used in combination with other features or steps from other embodiments described above. Reference numerals in the claims are not to be considered as limitations. The figures are merely schematic and not to scale.
