Definitions

  • the present invention relates to an elevator, in particular a passenger elevator.
  • the inventive elevator is particularly well suited to be used in various elevator shafts, in particular elevator shafts made of concrete or lightweight elevator shafts, for example made of glass or aluminum. It is also well suited for retrofitting.
  • elevators are typically built in an elevator shaft, which is part of the building shell.
  • the European patent 921 088 reveals an elevator with a typical elevator shaft. This is cast from concrete and has various access openings on its front. An elevator car runs in the shaft. At the back there is space for the lifting mechanism and a counterweight. A drive unit is provided at the upper end of the shaft. This drive unit is connected to the shaft wall and is supported by it.
  • the European patent specification 665 181 discloses an open elevator shaft and an elevator car adapted thereto.
  • such an elevator shaft can be manufactured with glass panels and a corresponding support structure. This usually occurs when a building is constructed.
  • the Japanese patent application JP 2006151625 A2 discloses an elevator with a compact guide and drive unit.
  • the elevator includes one Cabin with a square base.
  • the elevator shaft is also square.
  • Guide elements are provided to the left and right of the cabin. Additional drive and guidance elements are provided behind the cabin.
  • This also includes a counterweight that is guided on the rear wall of the elevator shaft.
  • the required shaft dimensions are significantly larger than the cabin dimensions. Only the front area of the shaft, in which access doors are provided, is free of technical components for drive and guidance. At the rear, the shaft must be significantly larger than the cabin, and large open spaces must also be provided in the shaft on the sides of the cabin.
  • This elevator is also intended for a shaft planned when the building was constructed.
  • the elevator is retrofitted after the building is constructed. It is common for an elevator shaft to be connected to a building wall.
  • the present invention aims to avoid the disadvantages of the prior art and to ensure that an elevator can be installed equally well in a prefabricated (concrete) shaft or in a subsequently installed shaft.
  • the present invention therefore desires to provide, in a simple economical manner, an elevator structure which is compact and suitable for many types of hoistways.
  • the elevator should be well suited for both original equipment in a building and for retrofitting. Economic advantages should be achieved by reducing the load-bearing capacity of the shaft walls and saving building materials accordingly.
  • An elevator according to the present invention can be a passenger or freight elevator. It includes an appropriately adapted cabin.
  • a passenger cabin will usually include at least one cabin door.
  • the elevator should include an external scaffolding that encloses an elevator shaft. It therefore forms the outer shell of the elevator shaft and determines its dimensions.
  • the outer framework includes a floor, a ceiling surface, a first side surface, an opposed second side surface, a third side surface and an opposed fourth side surface.
  • the base plate will usually be made of stone or concrete. This generally also applies to the side walls, which have the side surfaces mentioned available. It also applies to the ceiling, which closes the elevator shaft upwards along the ceiling surface, but is typically provided with bushings.
  • the elevator shaft can be built over a rectangular base and thus have a substantially cuboid shape. This means that it has four side walls that correspond to the side surfaces mentioned. Alternatively, other shapes are also possible, for example elevators are sometimes built over the base of an isosceles octagon. Then additional side surfaces are added to the four side surfaces mentioned. In the case of a substantially round shaft, the side surfaces can also be thought of as peripheral sections on a cylindrical surface.
  • the external scaffolding may be part of a building or may be constructed independently of the building.
  • a metal construction is often used.
  • the metal construction typically has four corner posts, which stand on a suitable base plate and are connected at least in the upper area by cross struts.
  • Such crossbars can also easily support a ceiling.
  • additional cross struts must be provided.
  • the walls of the external scaffolding can be closed with suitable panels; metal or plastic panels can be used. Glass panes are also often used.
  • the elevator should also have an internal framework.
  • the inner scaffolding consists of at least a first guide post and an opposite second guide post. These posts usually run in one piece over the entire length of the elevator shaft. But they can also be made in several pieces. These guide posts are used in particular to guide the elevator. Regardless of the lifting equipment, they ensure that the car in the elevator shaft moves in a fixed position.
  • the inner scaffolding will usually include a cross connection at the upper ends of these posts. This can be a crossbar, the guide post and crossbar would then form a kind of gate. The cross connection can also be made using a cover plate.
  • This interior frame can support the weight of the cabin.
  • the outer scaffolding can therefore serve to increase the stability of the inner scaffolding and in particular to prevent the inner scaffolding from tipping about an axis of rotation in the area of the base plate.
  • the outer scaffolding does not have to support the weight of the cabin. This represents a significant deviation from a conventional elevator construction. It is possible that, within the scope of the present invention, the outer frame also supports part of the weight of the car, for example 10% or a maximum of 20% of the weight.
  • the inner frame will bear the entire weight of the elevator.
  • the internal scaffolding is not suitable for providing the elevator without the external scaffolding.
  • the outer framework expediently serves to statically support the inner framework, in particular against movements from the vertical.
  • the side walls of the external scaffolding serve to securely separate the elevator from the surroundings. As a rule, shaft doors are also provided in the external scaffolding.
  • first guide post and the second guide post are arranged diagonally opposite each other, namely on the edge of the base plate. This leaves plenty of space between the guide posts to guide the cabin. If the side surfaces of the outer scaffold are arranged on a rectangle, the first guide post and the second guide post are usually positioned at opposite corners of this rectangle.
  • the inner frame can expediently also carry the drive unit.
  • the drive unit will usually consist of a motor, often an electric motor, and if necessary also a gearbox.
  • the drive unit will generally also include at least one driven wheel.
  • the drive motor drives two wheels, which are each located in corner areas of the outer scaffolding, expediently in those corner areas in which the guide posts of the inner scaffolding are also arranged.
  • a particularly useful construction results when the first guide post and the second guide post are connected to a cross brace.
  • This crossbar can be made in one piece or in several pieces.
  • a one-piece cross brace is definitely useful. This essentially results in a three-part internal framework, consisting of: the two guide posts and the cross brace. All three components as well as the inner framework as such can be made in one piece or in several parts.
  • the crossbar can in particular also carry drive elements.
  • the motor can be supported by the crossbar and is typically attached to the crossbar for this purpose.
  • a drive shaft can also be provided parallel to the cross strut. This drive shaft can also be mounted on the crossbar. It is expedient if a drive wheel is provided at one end, and it is often even more expedient for the elevator construction according to the invention if a drive wheel is provided in both end regions of the cross strut. An end region of the crossbar is to be understood as meaning the outer quarter or fifth of its length. It is advantageous if the crossbar runs diagonally in the shaft, i.e. in particular on the diagonal of a rectangle or square over which a cuboid-shaped shaft has been built.
  • the drive unit is usually arranged on a wider surface, for example on an intermediate floor or the shaft ceiling. Where two drive wheels are used, this is driven by a single electric motor via a deflection gear, from which two drive shafts then extend.
  • a single electric motor via a deflection gear, from which two drive shafts then extend.
  • a motor can be used for this purpose, preferably a gearless motor, which is also mounted on or on the crossbar.
  • the inner scaffolding supports both the weight of the cabin and the weight of the power unit, it is not necessary for the outer scaffolding to support a large load. This allows greater freedom of design Outdoor scaffolding. In the case of an external scaffolding made of concrete, this can save concrete (or a comparable building material). According to current knowledge, this has significant ecological advantages. If the external scaffolding is erected independently of the building, it is also advantageous if it can be dimensioned so that no heavy load has to be carried.
  • the first guide post is connected to the outer scaffolding with at least one spacer element.
  • spacer elements are used along the length of the elevator.
  • the second guide post is also connected to the outer scaffolding using spacer elements; advantageously, the same spacer elements are used as for the first guide post, usually at the same height.
  • Such a spacer element can be designed in such a way that a length of at least 2 cm is bridged, i.e. that the innermost point of the outer scaffolding and the outermost point of the inner scaffolding are 2 cm apart. It can be useful if this length is 5 cm to 10 cm, it can also be up to 20 cm, but more than 30 cm is usually not necessary. It is also possible for the elevator to use spacer elements of different sizes so that different lengths can be bridged. In this way, irregularities in the external scaffolding can also be compensated for. It is therefore possible to combine the interior framework with a large number of finished building shafts and easily compensate for construction defects.
  • Spacer elements that offer a mechanical connecting element to the outer scaffolding have proven to be particularly useful. This can be a tenon or a flat piece that can be easily inserted into a groove. A corresponding groove can be easily inserted (even continuously over all heights).
  • Provide external scaffolding Oriented towards the shaft, i.e. towards the guide posts, the spacer elements can expediently offer a differently constructed mechanical connecting element.
  • a mounting plate is well suited. Such a plate can have holes for receiving screws or bolts.
  • the guide posts are essentially provided by T-beams.
  • T-beam is inherently very rigid.
  • the base of the "T” is particularly suitable as a guide (i.e. as a guide rail), while the shoulders of the "T” allow the post to be well attached to the external scaffolding.
  • the shoulder side of the T is usually connected to the spacer element. (The horizontal line in the typeface represents the “shoulder side”.)
  • the guide posts essentially from steel. This means that they have sufficient connection rigidity and are also able to carry the load of the cabin and, if necessary, the drive unit.
  • Correspondingly stable guide posts allow the external scaffolding to be designed easily.
  • the outer framework can be made entirely or partially from aluminum. It is particularly useful if the corner posts of the external scaffolding are made of aluminum. As a rule, it is enough to use four corner posts to create a light and stable outdoor scaffolding.
  • At least one post of the outer scaffolding has a groove that is oriented towards the inner scaffolding. If the external scaffolding is erected on a rectangular surface, it is useful if the groove is oriented in the direction of the rectangle diagonal.
  • the corner posts expediently have a square cross-section. This can be chosen for at least two or all corner posts.
  • the groove can particularly conveniently provided at a 45 degree angle to the side surfaces. The orientation of this groove is then essentially towards the center of the shaft. It may be expedient to provide further grooves or fastening elements in addition to this groove in the side surfaces, i.e. in the direction of the side walls.
  • This groove is then particularly suitable for receiving the spacer elements with which the inner frame can be connected to the outer frame.
  • the groove can also accommodate other guide or control elements.
  • Fig. 1 shows a schematic perspective overall view of an elevator that can be used in the context of the present invention.
  • the elevator includes the elevator shaft 10. This is preferably built over a rectangular base area, i.e. overall cuboid. A square base is also useful.
  • the elevator shaft can be offered by a building, for example cast from concrete, or it can be made independently of the building using its own components.
  • an elevator shaft can be made from posts and struts and inserted panels. Such panels can be made of plastic, metal or glass.
  • the elevator shaft can also be designed for retrofitting to an existing building.
  • the elevator shaft comprises a front wall 12, followed by a side wall 14, followed by the rear wall 16 and, opposite the side wall 14, the side wall 18. According to the shaft design, all side walls have a substantially rectangular flat shape. The side walls are built above the floor 20.
  • Access openings are provided in the side walls, namely the access opening 22 on a first level in the front wall 12.
  • the access opening 24 is arranged above this in the side wall 18.
  • the access opening 26 is provided as a further access opening on a higher floor in the front wall 12.
  • the access openings are typically closed with shaft doors. All access openings can be provided on one side, for example all in the front wall 12, or the access openings can be provided in different side walls.
  • the elevator construction shown even allows access openings to be provided in all four shaft walls. This is not possible with normal elevators. However, this option creates great freedom for architectural design. It can also be a deciding factor as to whether an elevator can be retrofitted. When retrofitting, only certain access directions are often possible and it can easily happen that access on the ground floor has to be from the front, but on an upper floor it is only possible from one side.
  • the shaft 10 is limited at the top by the ceiling 28. However, it would be conceivable, especially within the scope of the present invention, to provide a shaft without a cover.
  • the internal scaffolding 30 is erected within the shaft 10. This consists of a first post 32, which is arranged in a shaft corner.
  • the second post 34 is arranged in the diagonally opposite shaft corner.
  • the two posts are connected by the cross brace 36, which runs diagonally in the upper area of the shaft. It can run directly below the ceiling 28.
  • the cross strut 36 can carry various components, symbolically shown here are drive rollers 38A and 38B, which are provided at the ends of the cross strut 36 adjacent to the posts 32 and 34.
  • the crossbar 36 can also carry a drive unit 40.
  • the drive unit 40 will generally comprise an electric motor which can drive the drive rollers 38 by suitable drive means, for example corresponding shafts.
  • Drive rollers are particularly suitable for driving toothed belts that can raise and lower an elevator car. This will be explained in more detail below.
  • Fig. 2 shows, in a floor plan-like cross section, an inner scaffolding and outer scaffolding according to the invention as well as an elevator car adapted to it.
  • the cabin 110 includes the floor 112 and also the first cabin door 140 and the second cabin door 146.
  • the floor 112 extends within a square, but is not itself square because the corners of the square are not filled.

  • the second access opening is located opposite the second side wall 116.
  • the side walls 114 and 116 converge at right angles to each other but do not touch each other. Rather, a first blunt corner 122 is provided in the area where the extensions of the side walls would intersect. A second obtuse corner 124 is provided opposite in the area in which the directions of the access openings intersect. A first acute corner is provided between the side wall 116 and the first access opening. A second acute corner is provided between the first side wall 14 and the second access opening.
  • a wall element 132 is provided between the first side wall and the second side wall 116. From the top view, there is a blunt corner between the side walls; from the inside view of the user, another wall element 132 or panel is easily visible. A corresponding wall element 134 is arranged in the second obtuse corner 124.
  • Wall elements are also provided in the pointed corners mentioned. In the first acute corner this is the wall element 136. In the second acute corner this is the wall element 138.
  • the first access opening is closed by a first cabin door 140.
  • the first cabin door 140 consists of two wings, namely the first wing 142 and the second wing 144.
  • the cabin door should open towards the second obtuse corner 124. This means that the first wing 142 moves when opened over a further distance than the second wing 144.
  • the first wing 142 is therefore referred to as the "fast" wing.
  • the second access opening is closed by the second cabin door 146.
  • This cabin door is three-wing.
  • the cabin door 146 includes the third wing 148 and the fourth wing 150. It also includes the fifth wing 152.
  • the wings 148 and 150 are also intended to open towards the second obtuse corner 124.

  • the fifth wing 152 is significantly shorter than the third wing 48 and the fourth wing 50.
  • the second cabin door can also be designed with four wings, two of which open in opposite directions.
  • the design of the cabin therefore allows short wall panels (such as 132 and 134) and blunt corners to be provided without disadvantages when using the cabin. These can be advantageously combined with an internal scaffolding.

  • the guide posts can provide an internal scaffolding. Accordingly, the guide posts are more often just referred to as guide rails. However, it is advantageous if the guide posts are self-supporting elements, which at least do not require any support from a shaft wall and also if the guide posts are supported on the shaft floor.
  • Fig. 3 shows an enlarged section of the shaft structure in the area of the corner post 166D.
