[0003] Elevator system

[0004] The invention relates to an elevator system for the transport of persons or goods.

[0005] Elevator systems for transporting people and goods contain elevator cars that move up and down vertically within an elevator shaft. The elevator cars are moved within the shaft by a drive unit via suspension elements such as cables or belts. Guide rails, fixed within the shaft, ensure precise linear guidance of the elevator car. In addition to the elevator car, the elevator system typically includes at least one counterweight that rotates in the opposite direction within the shaft. T-shaped metal profiles are commonly used as guide rails. Each T-profile has a base attached to the shaft wall and a web.The guide rail has two opposing guide surfaces and a guide surface on the side facing the elevator, along which a sliding or roller guide shoe can move. In addition to their guiding function, the guide surfaces of the guide rail also serve as attachment points for safety devices that can brake elevator cars to a stop or catch them in an emergency. The guide rail, designed as a T-profile, has proven its reliability for many years. US Patent 3,948,358 discloses an elevator system in which the guide rails are attached to a mounting bracket on both sides of each rail by means of rail clips.

[0006] It is an object of the present invention to avoid the disadvantages of the known invention and in particular to create an elevator system which enables quick and easy installation of the guide rail in the elevator shaft.

[0007] This problem is solved according to the invention with an elevator system having the features of claim 1. The elevator system has a vertical elevator shaft in which an elevator car can be moved up and down between floors along guide rails. At least one of the guide rails, and preferably each of the guide rails, is a guide rail formed by a T-shaped profile in cross-section (hereinafter also referred to as a "T-rail") with a rail foot and a rail web projecting at right angles from the foot, which has a guide section. The elevator system further has a mounting arrangement for connecting the respective guide rails shown in 2023P00368WÖ.

[0008] - 2 -

[0009] The guide rail is positioned in the elevator shaft, i.e., not directly against any shaft wall. The mounting arrangement comprises a number of mounting brackets distributed along the vertical travel path. Each mounting bracket has a preferably rigid receiving recess on one side for securing the guide rail. This recess is designed to hold the rail foot at its edge, specifically one leg of the rail foot. During installation, the guide rail can be placed against the mounting bracket, which is then slid laterally into the existing receiving recess. The mounting recess predetermines the position of the guide rail, eliminating the need for tedious alignment of the guide rail(s) after insertion into the shaft. The receiving recess(s) enable quick and easy installation of the guide rail in the elevator shaft.Another advantage is that the guide rail can be precisely mounted in the shaft in just a few steps.

[0010] The mounting bracket can therefore have a receiving recess on one side for fixing the guide rail and for more or less positively engaging the rail foot, with the receiving recess preferably being rigidly designed. Rigid means that it is fundamentally immobile and therefore, unlike the rail clamp, is designed to provide little or no clamping force; the clamping force can instead be generated by sliding the guide rail into the receiving recess.

[0011] The T-profile for the first rail comprises a rail foot and a rail web. The first rail has a guide section along which a guide unit associated with the elevator car can be guided. The rail web, or more precisely the guide section arranged on the rail web, has two opposing guide surfaces and a guide surface on the opposite side, along which, for example, a sliding or roller guide shoe can be moved as a guide unit, either sliding or rolling. In addition to their guiding function, the guide surfaces of the rail web can also serve as mounting surfaces for safety devices that can brake elevator cars to a stop. The safety device can also be a safety brake to catch the car.

[0012] The mounting bracket can include a support body against which the guide rail rests and is supported. The support body thus preferably forms a flat surface against which the underside of the rail foot rests. 2023P00368WÖ

[0013] - 3 -

[0014] The mounting bracket can, for example, comprise a crossbeam and two side beams projecting from the crossbeam into the shaft space. The mounting bracket thus forms a U-shaped bracket structure with the crossbeam and the two side beams. The crossbeam preferably runs along the shaft wall on the door side. The two side beams projecting from the crossbeam into the shaft space are preferably arranged at the ends of the crossbeam. The crossbeam can have a horizontal floor-fixing section that rests on and is fixed to a horizontal surface of the floor, so that the crossbeam is advantageously arranged essentially entirely within the floor. Consequently, in this preferred case, essentially only the side beams are positioned or arranged within the shaft space.Each side beam can have a rail mounting section running parallel to the door-side shaft wall at its front end for attaching the guide rail. Because the crossbeam can be positioned almost entirely within the floor slab, increased safety for the installer during elevator system installation is ensured. This rail mounting section forms the aforementioned flat surface against which the underside of the rail foot rests. The respective support body, against which the guide rail rests and is supported, can therefore be formed by one of the side beams. The side beam can also be constructed in multiple sections, with the support body being formed by a beam section that defines the front or free end of the side beam.

[0015] The guide rails can be connected to the elevator shaft in the area of ​​a door-side shaft wall of the elevator shaft, wherein the elevator system for this connection comprises at least one floor, preferably several floors, and particularly preferably one mounting bracket for each floor, to which the guide rails are attached.

[0016] In a first embodiment, the receiving recess can be formed by a nose molded onto a support body associated with the mounting bracket, and in particular onto the support body described above. The support body is thus part of the mounting bracket. The support body can therefore be an integral part of the mounting bracket and be integrally connected to the support body, i.e., formed from a single workpiece. 2023P00368WÖ

[0017] - 4 -

[0018] The receiving recess can be designed as a groove-like depression, preferably complementary to the edge area of ​​the rail foot. Preferably, the shape of the receiving recess can be adapted to the rail foot, more precisely to its edge. The edge of the T-rail foot can have a rounded upper side edge. Accordingly, the groove for the receiving recess can have a corresponding curvature. However, even for such T-rails, it is conceivable that the receiving recess does not follow this curvature and that the groove for the receiving recess has, for example, a rectangular or trapezoidal shape.

[0019] It can also be advantageous if the nose, together with the supporting body, is designed as a single metallic component.

[0020] Alternatively, multi-part designs are also conceivable, which can also offer advantages. For example, the receiving recess can be formed by an end piece attached to a support body to create a nose-like projection. Specifically, the receiving recess can be formed by an end piece attached to a support body of the mounting bracket, against which the guide rail rests and is supported, with the support body forming a flat surface against which the underside of the rail foot lies. An advantage of this embodiment is that for different rail types, not the entire mounting bracket, but only a different support body needs to be used, thus increasing the range of applications. Even in the multi-part design, a rigid receiving recess can be created, for example, by screwing the support body to the mounting bracket.The multi-part design may, under certain circumstances, allow for at least minor adjustments to the position of the guide rail. Compared to the one-piece design with the molded-on nose, this embodiment offers greater variability, as the separate end piece can be moved to a limited extent before final fastening. This variability could be further increased by providing an elongated hole in the support body for the screw connection.

[0021] The support body can be a metallic component, and the end piece can also be made of a metallic material. The end piece can be connected to the support body, for example, via a screw connection. 2023P00368WÖ

[0022] - 5 -

[0023] For particularly precise alignment, it can be useful to have a pin or other stop element positioned laterally in the mounting bay to provide a stop for the guide rail, so that the guide rail is laterally supported on this pin for precise positioning.

[0024] Furthermore, the guide rail can be attached to the mounting bracket on the other side, i.e., on the side opposite the side with the mounting bay, by means of a fastening element designed as a rail clamp (clip).

[0025] The elevator shaft typically has a rectangular shape when viewed from above and features a door-side shaft wall, parallel side shaft walls adjoining it at right angles, and finally a rear shaft wall adjacent to the back of the elevator car. The mounting bracket can be attached to a door-side shaft wall of the elevator shaft. As previously described, the mounting bracket can have a crossbeam running along the door-side shaft wall and two side beams projecting from the crossbeam, running along or towards the side shaft walls. The previously mentioned support structure is advantageously formed by the crossbeam.

[0026] At least one rail for guiding a counterweight can be mounted on the mounting bracket. There are two rails for each counterweight, with the counterweight positioned and guided between them.

[0027] The elevator system with the elevator car can include two counterweights that move in the opposite direction to the elevator car in the elevator shaft. In this case, two rails for guiding two counterweights can be mounted on the mounting bracket, with each rail guiding one of the two counterweights. The elevator system can be designed such that one counterweight can be guided by one of these rails alone, i.e., the counterweight is guided on one side only. The respective guide rail for guiding the elevator car and such a rail for guiding the counterweight can form a rail arrangement for simultaneously guiding an elevator car and a counterweight that moves in the opposite direction to the elevator car in an elevator shaft. This rail arrangement therefore comprises two rails: the first rail being, in a sense, the 2023P00368WÖ.

[0028] - 6 - The guide rail described here guides the elevator car, and the second rail is the one mentioned here for guiding the counterweight. This rail arrangement has several advantages. The guide rail designed as a T-profile has proven itself in conventional elevators for many years. Using such profiles reduces the costs of the rail arrangement. Standard elevator cars can also be used, and custom-made guide shoes as guide units are not required. The rail for guiding the counterweight can also be simple in design and therefore inexpensive to procure. The first and second rails can be arranged close together, forming a compact guide structure for the car and counterweight. Being close together means, for example, that the top view or...The cross-sectional area of ​​the minimal surrounding rectangular area (MUR) acted upon by the two rails is less than 1000 cm. 2 amounts.

[0029] Particularly preferably, the rail for guiding the counterweight can be a sheet metal rail comprising two longitudinal guides, each forming springs and preferably arranged in alignment. The rail can have side wall sections extending transversely to the longitudinal guides and preferably perpendicular to a flat base section connecting the longitudinal guides, and preferably adjoining the base section, the side wall sections forming lateral stops for support against the mounting bracket. For guiding the counterweight, sliding guide shoes, such as those shown in WO2022 / 136119, can be used.

[0030] In addition to the mounting brackets, further individual rail connectors can be provided. For example, each individual rail connector can be a metallic component used to space and secure the position of the two rails (1. guide rail for guiding the elevator car, 2. rail for guiding the counterweight).

[0031] Further individual features and advantages of the invention will become apparent from the following description of exemplary embodiments and from the drawings. These show:

[0041] Fig. 8 shows a rail arrangement equipped with derailment protection, with a lift car and counterweight guided on it.

[0042] Fig. 1 shows an elevator system, designated 1, for a multi-story building. The building has an elevator shaft 7 in which an elevator car 2 can be moved vertically up and down to individual floors for the transport of persons or goods.

[0043] The elevator system 1 is a traction elevator system with two counterweights 3, 3' moving in the opposite direction to the elevator car 2, as well as (not shown) load-bearing elements and drives. The two drives (e.g., traction sheave drives) drive the respective load-bearing elements (e.g., belts, steel cables) and thus move the elevator car 2 and the two counterweights 3, 3'. 2023P00368WÖ

[0044] - 8 - opposite. Each drive is assigned to one of the counterweights 3, 3'. To guide the elevator car 2 and the counterweights 3, 3', two opposing rail arrangements 4, 4' are provided on both sides of the elevator car 2. Each rail arrangement 4, 4' serves to simultaneously guide the elevator car 2 and a counterweight 3 or 3' moving in the opposite direction to the elevator car in the elevator shaft.

[0045] The elevator car 2 has a front with a car door 35, a rear opposite the front, and two car side walls 36 that connect the front and rear. The elevator car 2 is supported at the front. The rail assemblies 4, 4' are located on opposite sides of the elevator shaft 7, adjacent to the side walls 36. The rail assemblies 4, 4' are mounted in the elevator shaft 7 by means of horizontal mounting brackets 10, which are fixed to the front of the elevator shaft, for example, at the level of the floor.

[0046] The rail arrangements 4, 4' each have two rails, with a first rail 5 serving to guide the elevator car 2 and a second rail 6 serving to guide the counterweight 3. The first rail 5 for guiding the elevator car 2, which is hereinafter referred to as the "guide rail", is a rail formed by a T-shaped profile in cross-section. The second rail 6 is formed by a flattened profile, which in this case is designed as a flat steel bar. The guide rail 5 and the rails 6 are connected to each other by means of the mounting bracket 10, which holds the rails 5, 6 together at floor level. In addition to the mounting bracket 10 as a rail connector, further rail connectors can be used to connect the rails 5, 6 between floors to stiffen the rail arrangement.The rail arrangement 4 is shown and described in detail below, along with its various configurations. The rail arrangement 4' for guiding the elevator car 2 and the counterweight 3' is a mirror image and therefore has a similar structure. It should also be noted that the use of rail arrangement 4, or a similar rail arrangement, is conceivable for elevators with one car and only one counterweight.

[0047] The rail arrangements are located in the area of ​​the door-side shaft wall via the mounting brackets.

[0048] 10 is connected to elevator shaft 7. The elevator system includes the connection to 2023P00368WÖ.

[0049] - 9 - Each rail assembly for at least a portion of the floors has a mounting bracket 10 to which the rail assemblies are attached. Preferably, each floor has one such mounting bracket 10 to which the rail assemblies are attached. The plurality of mounting brackets 10 form a mounting arrangement for connecting the rails 5, 6 located in the elevator shaft, i.e., not directly against a shaft wall. Each mounting bracket 10 has a crossbeam 41 with a horizontal floor-fixing section that rests on and is fixed to a horizontal surface of the floor. Side supports 42 connect to the crossbeam 41, with a wedge-shaped or triangular fastening section (in plan view) being provided at the front end of each side support 42, to which the first and second rails 5, 6 are attached.

[0050] Fig. 2 shows a rail arrangement 4 for the previously described elevator system 1. The guide rail 5 (hereinafter referred to as "T-rail"), formed by the T-shaped profile in cross-section, for guiding the elevator car 2, consists of a rail foot 12 and a rail web projecting perpendicularly from the rail foot, with the guide section 11. A guide unit 8 associated with the elevator car can be guided along the guide section 11. The T-rail 5 can be formed from a rolled, drawn, or extruded solid steel profile. T-rails known per se in the elevator industry can be used for the rail arrangement 1 presented here. These T-rails are inexpensive and readily available in bulk. In this case, the guide unit 8 of the elevator car 2, designed as a sliding guide shoe, engages the guide section 11 on the web side. Alternatively, roller guide shoes could, of course, also be used as guide units.The T-rail 5 is attached on one side to the mounting bracket 11 by means of fastening elements 20 in the form of rail clamps, also known as "clips". On the other side, the mounting bracket 11 has a receiving recess 30 for receiving the rail foot 12 at its edge and for fixing the guide rail 5.

[0051] The rail 6 for guiding the counterweight 3 is formed by a flat steel bar, according to the present embodiment. The flat steel rail 6 is fastened to the mounting bracket 10 by means of screws 25, which are illustrated only as an indication. The flat steel bar provides two longitudinal guides 13, 14, each forming a spring, which are thus aligned with each other. The longitudinal guides 13, 14 evidently provide a type of slide guide for the counterweight 3. A guide unit 9 2023P00368WÖ is attached to the counterweight 3.

[0052] - 10 - arranged, comprising two opposing sliding pieces 38 with U-shaped channels complementary to the longitudinal guides 13, 14. The rail arrangement 4 is designed such that it can guide the counterweight on its own or on one side by means of the rail 6.

[0053] The mounting bracket 10 comprises the crossbeam 41 and two side beams 42 projecting at right angles from the crossbeam. At the front end of each side beam 42, a wedge-shaped or triangular mounting section (in plan view) is provided, to which the guide rail 5 and the rail 6 are attached. The two rails 5 and 6 each lie on vertical planes that intersect at acute angles. Each floor can have one such mounting bracket 10 to which the rail assembly 4 is attached. The mounting brackets 10 connect the guide rail 5 and the rail 6 section by section with respect to the vertical direction of travel z. The mounting brackets 10 thus form rail connectors distributed along the vertical direction z and preferably spaced at regular intervals, depending on the building.

[0054] Reference numeral 31 designates a support body against which the guide rail 5 rests and is supported. This support body 31 forms a flat surface against which the underside of the rail foot rests. In this case, the support body 31 is formed by the front or free end of the side support of the mounting bracket 10. The aforementioned receiving recess 30 for receiving the rail foot 12 is adapted to the shape of the rail foot or its edge. The receiving recess 30, defined by the lug 32, is rigidly designed. The lug 32 is integrally formed with the support body 31 and connected to it as a single piece; the lug 32 is thus, in a sense, an integral part of the mounting bracket. Preferably, the lug 32 together with the support body 31 is formed as a single metallic component.The guide rail foot 12 is received more or less positively by a rigid receiving recess 30, meaning that the guide rail 5 is not clamped or only slightly clamped on this side. However, a clamping force can be achieved by inserting the guide rail 5 into the receiving recess 30, into which one leg edge or one edge area of ​​the guide rail foot can engage. The receiving recess 30 can be dimensioned for clamping, for example, according to an interference fit. Alternatively, clamping can be achieved by a wedge-shaped ramp on the nose. 2023P00368WÖ.

[0055] - 11 -

[0056] In addition to the mounting brackets 10, further rail connectors can be provided to connect the two rails 5, 6. One such additional rail connector is shown in Fig. 3 and is designated there by 21. The purpose of this single rail connector 21 is to stiffen the rail arrangement 4. Preferably, at least one or more single rail connectors 21 can be inserted between the mounting brackets 10. The respective rails 5, 6 are connected to the rail connectors 21 in a similar manner to the mounting brackets. The guide rail or T-rail 5 is attached on one side by means of fastening elements in the form of rail clamps (clips), and on the other side, the rail 6 is screwed directly to the single rail connector 21, which is preferably designed as a metallic molded body.

[0057] Details of a rail arrangement 4 for simultaneously guiding an elevator car 2 and a counterweight 3 moving in the opposite direction to the elevator car in an elevator shaft can be seen in Fig. 4. The first rail 5, i.e., the T-rail, which consists of a rail foot 12 and a rail web projecting at right angles from the rail foot with the guide section 11, is connected to the mounting brackets 10 on one side by means of clips. On the other side, a rigid receiving recess is provided for securing the T-rail 5 by means of an edge-mounted receiving recess for each rail foot 12. The receiving recess is evidently formed by a lug molded onto the side of the mounting bracket where the rail 5 rests and is supported. The second rail 6 is also formed by a flattened profile.In this embodiment, the second, inclined rail 6 consists of a sheet metal part and has a C-shaped cross-section. The rail 6, designed as a sheet metal part with a C-shaped cross-section, has longitudinal guides 13, 14 defined by the bends at the edges. A difference from the previous embodiment is that the counterweight is guided by rollers designated 39.

[0058] The second rail 6, designed as a sheet metal part, comprises a flat base section 15 between the longitudinal guides 13, 14. The free end of the side support 42 of the mounting bracket 10, projecting into the shaft space, has an inclined support wall section against which the rail 6 rests via its base section 15 and is connected to it, for example, by a screw connection. Holes for the fasteners, in the form of screws or bolts, are provided in the flat base section 15 for attaching the rail 6 to the mounting bracket 10. The guide rail 5 and the rail 6 are, as shown in 2023P00368WÖ

[0059] - 12 - as can be seen from this and the other figures, are arranged close together and thus form a compact guide arrangement for the cabin and counterweight. The minimal surrounding rectangular area (MUR, rectangular sides parallel to the shaft walls) acted upon by the two rails 5, 6, as seen in plan view or cross-section, is less than 1000 cm². 2 The rail foot 12 of the T-rail 5 faces the base section 15 of the rail 6. The gap between the two rails is bridged by the rail joiner.

[0060] The guide surface 11 of the rail web serves not only as a guide but also as an attachment point for safety devices that can brake elevator cars to a stop. The safety device can alternatively or additionally be a safety brake to catch the car. One such safety device is shown in Fig. 4 and labelled 28.

[0061] The rail assembly 4 shown in Fig. 5 also has a sheet metal rail 6 for guiding the counterweight 3, which rail 6 has a C-shaped cross-section. The rail assembly 4 with the T-rail 5 and the rail 6 are connected to each other in the relevant section by a single rail connector 21. The rail connector 21 forms or corresponds to the support body 31, against which the guide rail 5 rests and is supported. The T-rail 5 is fixed to the single rail connector 21 on one side by means of the fastening element 20 in the form of a rail clamp known per se. On the other side, the T-rail 5 is inserted into the receiving recess 30 defined by the lug 32 and thus secured on this side. A screw 23, which is screwed into the single rail connector 21, is also visible.For each individual rail connector 21, it may be advantageous to use two such screws for secure fastening (see Fig. 6).

[0062] The singular rail connector 21 has a wedge-shaped base, with comparatively narrow connector sections adjoining the base at the opposing ends associated with the screw connections, thus eliminating the need for unnecessarily long screws 23, 25. The singular rail connector 21 is preferably designed as a metallic form to space and secure the position of the two rails 5, 6. 2023P00368WÖ

[0063] - 13 -

[0064] Constructive details for the design of a single rail connector 21 can be seen in Fig. 6, which relates to a rail arrangement 4 similar to the embodiment shown in Fig. 5. For each single rail connector 21, it can be advantageous to use at least two screws 23, 25 for secure fastening.

[0065] Fig. 7 shows another embodiment of a rail arrangement 4 for simultaneously guiding an elevator car 2 and a counterweight 3 moving in the opposite direction to the elevator car. The arrangement comprises a first rail 5, formed by a T-shaped profile in cross-section, for guiding the elevator car 2; a second rail 6, designed as a sheet metal part, for guiding the counterweight 3; and rail connectors defined by mounting brackets 10 for connecting the two rails 5 and 6. The rail arrangement 4 has a specially shaped second rail 6 for guiding the counterweight 3. The second rail 6, designed as a sheet metal part, is a profile with folded edges forming folds as longitudinal guides 13 and 14, or it is a C-shaped profile in cross-section.The mounting bracket 10, or more precisely a support part defining the front or free end of the side carrier 42, forms or corresponds to the support body 31, against which the guide rail 5 rests and is supported.

[0066] For lateral support and securing, the rail 6 has side wall sections 16 and 17 that adjoin a flat base section 15 at right angles with folded edges. The mounting bracket 10, or more precisely, a portion of its free end, is positioned and accommodated between the side wall sections 16 and 17. The side wall sections 16 and 17 lie flush against wall sections of the rail connector.

[0067] In contrast to the previous embodiments, the nose is not formed as a single metallic component together with the support body, but rather the present embodiment involves a multi-part assembly for creating the receiving recess 30. The receiving recess 30 is formed here by an end piece 33 attached to the support body 31 or the mounting bracket 10 to form a nose-like projection. For this purpose, the end piece 33 has a recess adapted to the shape of the rail foot. The end piece 33, like the support body 31, can be made of a metallic material. The end piece 33 can be connected to the support body 31 via a screw connection. 2023P00368WÖ

[0068] - 14 -

[0069] The rail arrangement 4 shown in Fig. 8 is a custom-made design that can be used, for example, in earthquake-prone areas. The second rail 6, i.e., the rail for guiding the counterweight 3, has a hook-shaped end section 18 to form derailment protection for the elevator car 2. The end section 18 is directed towards the guide section 11 of the T-rail 5. It runs perpendicular to the direction of extension of the rail web, or in other words, parallel to the adjacent shaft wall. The hook-shaped end section 18 is operatively connected to an L-shaped retaining element 27 (in plan view), which prevents the guide unit 8 of the elevator car 2 from being separated from the guide section 11.

[0070] In this embodiment as well, the receiving recess 30 is formed by an end piece 33 attached to the support body 31 or the mounting bracket 10 to create a nose-like projection. A pin 34 is arranged laterally in the receiving recess 30 to provide a stop for the guide rail 5. Thanks to the pin 34, the guide rail 5 is laterally supported, thus enabling precise positioning of the guide rail 5.
