Abstract

The invention relates to an elevator system (1) which has an elevator shaft (3) and typically an elevator car (5), a lifting platform (11), and a supporting means (9). The elevator system (1) is preferably formed as a climbing elevator system, wherein, in the course of different construction phases of a building, the lifting platform (11) can be anchored at various positions within the elevator shaft (3). Provided in the elevator shaft (3) is a protective roof (21), which is preferably arranged above components of the lifting platform (11) that are to be protected, such as a drive machine (15). The protective roof (21) has a central roof structure (23) and a peripheral flank structure (25). The flank structure (25) has flank walls (27) which are fixed to the lateral edges (30) of the central roof structure (23) and which are arranged to project outward from the central roof structure (23) at an angle with respect to the horizontal. Because of the inclined arrangement of the flank structure's flank walls (27), the flank structure (25) can better withstand falling objects and better protect components located underneath. Cantilevered edge regions (32) can possibly be supported on side walls (4) of the elevator shaft (3).

Description

Elevator installation, in particular in the form of a climbing lift system, with a specially designed protective roof

The present invention relates to an elevator installation, in particular in the form of a climbing lift system, with a specially designed protective roof.

Lift systems are generally used to be able to carry persons or objects in a usually vertical direction within existing buildings. For this purpose, an elevator car can be used by means of a suspension device, such as one or more ropes or belts are displaced within a hoistway.

Before the elevator system can be operated in its normal mode of operation, it may already be installed in the building during a construction phase during which a building is not yet finished. It is then possible that the elevator system is already used during the construction phase for the transport of people and / or material, and that it grows with you during the construction of the building. In this way, during the construction phase, for example, to separate external lifts, which would be to install, for example, on an outside of the building, be dispensed with.

For this purpose, for example, a part of guide rails and an elevator car in the elevator shaft provided for the elevator shaft are already mounted at a time when only one or more lower floors of the building have been completed. The elevator car and other components of the elevator system such as e.g. a counterweight can typically be hanged by means of the suspension to a lifting platform. On the lifting platform, a drive machine can be provided, which can displace the support means, for example by means of a traction sheave. The

Lifting platform can be raised for example by crane or other means to a next higher level to extend the transport path of the elevator system.

For example, in a so-called climbing lift system, the guide rails and / or holding rails of the elevator system provided for guiding the lifting platform can be successively mounted in the elevator shaft during the construction phase of the building, and the lifting platform can be attached to the guide rails or support rails as required transported above. The lifting platform can then be fixed at a desired higher position, for example with struts that can be pushed out of the lifting platform, for example, into openings in the walls of the elevator shaft.

WO 2015/003964 AI shows an example of a climbing lift system.

In particular for a lift installation used during the construction phase of a building, there may be a risk that components of the lift installation will be damaged by dirt or falling objects. Also, persons within the hoistway, such as maintenance personnel, e.g. to be damaged by falling objects.

There may, inter alia, be a need for an elevator installation in which components of the elevator installation and / or persons located in the elevator shaft are efficiently protected against falling objects or dirt.

Such a need can be met by the subject-matter of the independent claim. Advantageous embodiments are the dependent ones

Claims and the following description defined.

According to one aspect of the invention, an elevator installation is proposed which has at least one elevator shaft and typically also at least one elevator car, a lifting platform and a suspension device. The elevator car is held by the support means and can be displaced by means of the support means within the hoistway. The support means in turn is held on the lifting platform, for example, firmly anchored or extending over a roller. In the elevator shaft, preferably above the lifting platform, a protective roof is provided. Such a protective roof is sometimes referred to as a crash deck. The protective roof is preferably above to be protected components of the lifting platform or above a working plane, for example, the pit, arranged. The canopy has a central roof construction and a peripheral flank construction. The

Flank construction has flank walls, which are attached to the roof structure, preferably on lateral edges of the roof construction, and which inclined towards a horizontal inclined from the central roof construction are arranged outwardly projecting.

Possible features and advantages of embodiments of the invention can be considered, inter alia, and without limiting the invention, as being based on the ideas and findings described below.

Embodiments of the elevator system proposed herein correspond to conventional elevator systems with regard to many of their components. Among other things, an elevator installation according to the invention generally has an elevator car in which persons or objects can be transported. The elevator car is usually vertically displaceable within the elevator shaft. For this purpose, the elevator car is held by the support means such as ropes or belts and the support means is in turn held on the lifting platform located further up. The lifting platform is thus designed, on the one hand, to hold the weight of the elevator car and possibly also a counterweight, likewise fastened to the suspension element, by means of the support means held on it. On the other hand, the support means should be held on the lifting platform so that they can be relocated and thus held on the suspension means elevator car can also be relocated. For this purpose, if appropriate, a drive machine which serves to drive the suspension element can be arranged on the lifting platform. For example, the prime mover can drive a traction sheave in a rotating manner and the carrying means can be placed around the traction sheave in order to be able to be displaced therefrom. Alternatively, only deflection rollers can be provided on the lifting platform around which the suspension element is wound, and a drive machine can be arranged at another position within the elevator shaft or within a machine room in order to be able to displace the suspension element. Other configurations in which the support means on the lifting platform fixed or held relative to this displaceable, can be used.

Embodiments of the elevator system proposed herein differ from conventional elevator systems, in particular by the protective roof to be provided in the elevator shaft and its specific configuration. Among other things, the protective roof is intended to protect components of the lifting platform located below the protective roof, in particular against falling objects falling from above and possibly also dirt or water. Even persons located below the protective roof in the elevator shaft can be protected.

This can be particularly advantageous when the elevator system with their

Lifting platform is designed to be temporarily attached to different positions within the hoistway, that is, when the elevator system as

Climbing lift system is designed to be used during a construction phase in a building and grow during this construction phase by successively moving the lifting platform quasi with the building. During such a construction phase, the elevator shaft in the building is typically still open at the top.

In addition, the lifting platform is typically not located at a highest point of the building or at least the hoistway, as is typically the case with completed buildings. Therefore, there may be an increased risk that objects coming from further up in the building, such as, for example, screws or tools, accidentally fall into the elevator shaft and thus damage components of the elevator installation, in particular the lifting platform or any prime mover possibly arranged there. sensitive

Components of the lifting platform or the engine can also be damaged by coming from above dirt or water, such as rain.

In order to prevent such damage as possible, is used in conventional

Climbing lift systems provide a protective roof above components to be protected.

However, it was recognized that commonly used protective roofs are often very expensive to mount on the lifting platform. In particular, it was usually difficult to mount the canopy so that as possible no gap or at most a very narrow gap between the canopy and walls of the elevator shaft remains, could pass through the falling objects. A hitherto necessary complex mounting and adjusting the protective roof to a geometry of the

Elevator shaft often meant that when moving the lifting platform within the elevator shaft, a considerable additional effort alone by doing this first necessary dismantling and then after relocation necessary new mountings of the protective roof could arise.

It was also recognized that in conventional canopies sufficient stability and thus resistance to falling objects could be ensured only with great effort. Especially in border areas, in which the canopy adjoins walls of the hoistway, the canopy had to be made very stable, which could bring a high design and material and weight overhead.

In order to overcome deficits of conventional canopies, it is proposed for embodiments of the elevator installation according to the invention to assemble the protective roof from a central roof construction and a peripheral flank construction.

The central roof construction can be arranged above central areas of the lifting platform and cover these. In particular, the central roof structure may be configured and dimensioned to be e.g. does not need to be dismantled when the lifting platform is to be relocated within the hoistway. For example, the central roof structure may be sized such that its edges are sufficient from sidewalls of the hoistway, i. For example, at least 10cm, preferably at least 30cm, are spaced apart. The central roof construction may, for example, a plate made of a sufficiently stable material, for example a metal plate with one for a

Protective function sufficient thickness of typically at least 3mm, preferably at least 5mm. It can also be composed of several plates.

Adjacent to the lateral edges of the central roof construction are each followed by areas of the peripheral flank construction. The peripheral

Flank construction is thus arranged predominantly in areas between the central roof construction and surrounding side walls of the elevator shaft. The peripheral flank construction covers these areas as much as possible. A combination of central roof construction and peripheral flank construction thus covers wide areas of the cross section of the hoistway. As further described below, any remaining gaps between the flank construction and The walls of the elevator shaft should be as small as possible so that no objects of significant size can pass through them. Components or persons located underneath the protective roof are thus well protected against falling objects.

The flank construction of the protective roof is designed in a special way. It has flank walls at the lateral edges of the central

Roof construction are attached. These flank walls protrude from the roof construction towards the outside, that is, toward a respective adjacent wall of the elevator shaft. However, the flank walls are not aligned horizontally, but extend at an angle inclined to the horizontal. In other words, the protective roof does not extend horizontally, in particular at its lateral edges formed by the flank walls, but inclined to the horizontal, preferably at an acute angle.

The inclined arrangement of the flank walls can advantageously have the effect that forces acting on the protective roof locally at its edge and caused by falling objects can be reduced. A falling object does not bounce on a horizontally extending portion of the protective roof and thus transmits there locally a significant impulse. Instead, the falling object bounces off the sloped flank wall and becomes sideward, i. as far as the central roof construction, distracted. In this case, on the one hand, only a modest amount of momentum impulse is exerted on the flank wall in the lateral region of the protective roof, on the other hand, the effect on the flank wall force effected in an advantageous manner such that the force can be well derived on the central roof construction or on the side walls.

Overall, by providing a tilted to the horizontal

Flank construction can be achieved that a mechanical stability of the protective roof can be improved, especially in these vulnerable edge areas. The fact is taken into account that especially in these marginal areas, the risk that the canopy is hit by falling objects, is particularly high and that on the other hand, it is difficult, the canopy in these edge areas sufficiently stable to construct. The protective roof can thus be made sufficiently stable with relatively little design effort.

According to one embodiment, the flank walls are fastened with their lower end regions to the roof construction. In other words, the flank walls are secured at the bottom to the edges of the central roof structure and then protrude obliquely upwards from the central roof structure. The inclined arranged flank walls can thus form a kind of funnel, so that objects falling from above onto the flank walls are deflected towards the central roof construction and can be collected there.

According to one embodiment, the flank walls are arranged at an angle of between 20 ° and 70 °, preferably between 30 ° and 60 °, more preferably between 40 ° and 50 °, to the horizontal. Flank walls aligned at such an acute angle to the horizontal can, on the one hand, well deflect falling objects without themselves becoming overly mechanically stressed. The larger the angle to the horizontal is selected, the smaller are the forces exerted on the flank walls during the impact. On the other hand, the inclined flank walls at such a higher selected angle to the horizontal must be made wider to an area between a central roof construction and the walls of the

Bridge shaft to be able to bridge. However, the inclined flank walls should not be excessively wide for the sake of the lowest possible material consumption. The smaller the angle to the horizontal, the narrower it is

Flank walls can cover this area.

The flank walls can be flat, for example in the form of flat sheets. In this case, their angle to the horizontal is clearly defined. But the flank walls can also be bent in itself, so that one and the same flank wall may include different, inclined at different angles to the horizontal areas. By "the angle to the horizontal" in this case an average angle to the

different areas of a flank wall are understood.

According to one embodiment, the peripheral flank walls are reversibly detachably fastened to the central roof construction. In other words, the

Flank walls on the roof construction repeatedly mounted and dismounted become. The central roof construction and the flank walls to be attached thereto are provided as separate and detachably connected components.

If the lifting platform is raised to a different height within the elevator shaft as a result of a construction phase progress, it may be necessary to temporarily dismantle parts of the protective roof at least in places during this displacement, since otherwise it could hinder the displacement of the lifting platform. At the here

it may be sufficient to merely dismantle the flank construction so that it does not come into conflict with components protruding into the elevator shaft, for example, during the displacement of the lifting platform. Once the lifting platform has arrived at its new position and anchored, the canopy can be completely re-assembled, that is, the flank walls are attached to the roof structure.

In this case, according to one embodiment, it may be advantageous to fasten the flank walls to the central roof structure by means of a fastening construction, wherein the fastening structure is designed to releasably secure fastening of the flank walls and to positions spaced apart from a respective edge of the roof construction ,

In other words, may be provided for attaching the flank walls to the roof construction, a special mounting structure, which on the one hand allows to fix the flank walls releasably attached to the central roof construction, and on the other hand configured such that the flank walls at different positions relative to the edge the central roof construction can be fixed.

With the aid of the fastening construction, a flank wall can thus be moved closer to or farther away from the respective edge of the roof construction as required

Roof construction to be fixed so that it protrudes correspondingly more or less far laterally over the roof construction. This allows the positioning of the

Flank walls, for example, be adapted to locally changing conditions within the elevator shaft. The mounting structure should advantageously allow infinitely variable positioning of the respective flank wall. According to a specific embodiment, the fastening structure can have a reversibly detachable and fixable tongue and groove connection which, in an open state, holds the flank wall in only at least one spatial direction, preferably in two spatial directions, and which in one fixed state holds the flank wall in three Spatial directions holds.

In other words, a flank wall can be fastened to the roof construction with a fastening device designed as a tongue and groove connection. The tongue and groove connection should be both stable fixable and reversible solvable. In a fixed state, the tongue and groove connection holds the flank wall stable in position, so that the flank wall can not move significantly in any direction in space. In the fixed state, the flank wall is thus held in three mutually orthogonal spatial directions. The spatial definition of the flank wall can be effected both by positive engagement and by frictional connection, which are caused by the tongue and groove connection.

However, the tongue and groove connection should be able to be solved reversibly, wherein in an open state, the flank wall is held only in two spatial directions, preferably by positive engagement, and thus along one of these two

Spaces orthogonal direction can be shifted. Preferably, this third, in the open state freely displaceable spatial direction extends orthogonal or at least obliquely transverse to the edge of the central roof construction.

Accordingly, the flank wall can be moved orthogonal or obliquely to this edge of the central roof construction with released tongue and groove connection.

Such, in the released state of the tongue and groove connection approved

Displaceability of the lateral flank walls can be used inter alia to temporarily move the flank walls towards the center of the roof construction, for example, the roof construction together with the lifting platform within the

Elevator lift can lift higher. The flank walls need not be completely removed, but it may be sufficient to solve the tongue and groove connection and to move the flank walls only to the inside, but they are still held in the other two spatial directions. At the new position for the lifting platform, the flank walls can then move outwards again to walls of the elevator shaft, are pushed and then the tongue and groove connection are established.

According to one embodiment, the flank walls are to be fastened to the roof construction in a position and orientation in which edge regions of the flank walls which are arranged opposite to end regions of the flank walls fastened to the roof construction are less than 30 mm, preferably less than 10 mm, of side walls of the elevator shaft. are spaced. Alternatively, the flank walls may be secured to the roof construction in a position and orientation in which edge regions of the flank walls, which are disposed opposite end portions of the flank walls secured to the roof structure, are disposed adjacent the sidewalls of the hoistway.

In other words, the flank walls themselves, as well as the fastening structures used to secure them to the roof construction, can be configured such that each of the flank walls can be secured in position and orientation to the roof structure in which the flank wall extends almost to an adjacent side wall of the roof Elevator shaft extends. To the central roof construction directed end portions of the flank walls are attached to the roof construction. Edge regions opposite to these end regions extend to just in front of the adjacent wall of the elevator shaft, so that any remaining gap between the flank wall of the protective roof and the side wall of the elevator shaft is very small, in particular smaller than 30 mm, and thus heavy objects can hardly fall through such gaps ,

Alternatively, according to an embodiment, the flank walls on the

Roof construction to be fixed in a position and orientation in the

Edge regions of the flank walls, which are arranged opposite to the roof structure fixed end portions of the flank walls, abut against side walls of the elevator shaft.

In this case, the flank walls should be able to be fastened to the central roof structure in such a way that their outer edge areas do not remain spaced from the respectively adjacent side wall of the hoistway, but can mechanically abut against it. The flank wall can thus with its outside Supporting edge region on the side wall of the elevator shaft. This can further increase a mechanical strength of the flank wall. For example, on impact of a falling object on a flank wall occurring forces on the one hand in the central roof construction, on the other hand, but also partly in the contacted by the flank wall side wall of the elevator shaft are derived.

According to one embodiment, the flank construction has corner constructions. In this case, a corner construction has two corner flank walls which are at an angle to one another and are fastened to one another along an edge and in each case inclined relative to the horizontal.

In other words, the flank construction may have special corner constructions. Each corner construction has two corner flank walls. These

Edge flank walls adjoin one another at one edge and are fastened to one another along this edge. An attachment of the two corner flank walls can be reversible or irreversible. In particular, the two corner flank walls along the edge can be reversibly screwed together or, preferably, irreversibly welded together, riveted or the like. In this case, the corner flank walls are designed and connected to one another in such a way that they are arranged at an angle relative to one another and both are arranged inclined relative to the horizontal. In other words, a corner construction may have a shape of a corner of an upwardly opening, angular funnel.

The corner constructions can be provided as separate components, which are each independent of each other and / or independent of other parts of the

Fix the flank construction to the central roof structure.

According to one embodiment, a corner construction may be provided by means of a

Corner mounting structure to be attached to the roof construction. The

Eckbefestigungskonstruktion can thereby be designed to releasably secure the corner structures and at different from a respective corner of the

Roof construction to allow spaced positions. In other words, it can be provided a corner construction on the

Roof construction to be detachably fastened at different positions. The positions can be more or less close to a respective corner of the

Roof construction lie. A corner construction fastened to the roof construction in its lower end regions can then protrude beyond the edges of the roof construction near the respective corner with its inclined edge walls arranged inclined to the horizontal and extend into one of side walls of the roof

Lift shaft formed corner extend.

A corner construction can fill as completely as possible a corner of the elevator shaft in the mounted state. For example, a lateral distance between the corner construction and a respective side wall of the hoistway may be less than 30mm. Alternatively, the corner construction with its cantilever edge abut the respective side walls of the elevator shaft. Column between the

Side walls of the elevator shaft on the one hand and the protective roof on the other hand can thus be prevented or at least minimized.

According to one embodiment, the corner fastening construction can have a reversibly detachable and fixable tongue and groove connection. This tongue and groove connection, in an open state, similar to the above-described tongue and groove connection, hold the corner construction in only at least one spatial direction, preferably in two spatial directions, and hold the corner construction in three fixed directions in three spatial directions ,

In other words, in turn, a tongue and groove connection can be used to releasably secure a corner construction to the central roof structure such that the corner construction in the open state of the tongue and groove connection along the central roof construction toward or away from a corner the same can be moved.

The corner constructions can thus be temporarily shifted, for example, to the center of the central roof structure in order to be able to relocate the lifting platform together with the protective roof, for example. After reaching a target position, the canopy can be mounted again so that it is the cross section of the Lift shaft essentially completely covered. For this purpose, the

Corner structures are pushed outwards to the corners of the elevator shaft and then the tongue and groove connection are established.

According to one embodiment, the flank walls can have a wall thickness of at least 3 mm, preferably at least 5 mm. By means of such a wall thickness, a sufficiently high mechanical strength of the flank walls can be achieved. In particular, it can be achieved that flank walls can not be easily penetrated by falling objects.

According to one embodiment, the flank walls are made of metal or a composite material provided with a metal layer. Although the flank walls can in principle consist of any sufficiently mechanically stable material such as, for example, plastic, plastic composite materials, wood,

Wood composite materials or the like. However, it is considered advantageous to form the flank walls of metal or at least with a metal layer, since on the one hand sufficient mechanical strength, but on the other hand, a simple production can be achieved with low manufacturing and material costs.

It should be understood that some of the possible features and advantages of the invention are described herein with respect to various embodiments. One skilled in the art will recognize that the features may be suitably combined, adapted or replaced to provide further embodiments of the invention.

Hereinafter, embodiments of the invention will be described with reference to the accompanying drawings, wherein neither the drawings nor the

Description are to be construed as limiting the invention.

In the following the invention will be explained in more detail with reference to figures. Show it:

The figures are only schematic and not to scale. The same reference numerals designate the same or gl cally acting features in the various figures

Fig. 1 shows an elevator system 1 in the form of a climbing lift system according to a

Embodiment of the present invention.

The elevator installation 1 comprises an elevator shaft 3 in which an elevator cage 5 and a counterweight 7 are accommodated. The elevator car 5 and the counterweight 7 are held by means of a support means 9 on a lifting platform 11. The support means 9 typically comprises several ropes or belts. The lifting platform 11 is fixed at least temporarily firmly in the elevator shaft 3. At the lifting platform 11 are

Attachment points 13 attached to which ends of the support means 9 are held firmly. Furthermore, a drive machine 15 is provided on the lifting platform 11. This drive machine 15 drives a traction sheave 17 rotating. The support means 9 is wound around the traction sheave 17 and thus can be displaced by the rotating traction sheave 17, whereby the elevator car 5 and the counterweight 7 within the

Elevator shaft 3 can be moved in opposite directions.

The elevator installation 1 is designed to be used already during a construction phase in a building. This means that the elevator installation 1 can already be operated if the building receiving it is only partly completed. After certain construction steps, the lifting platform 11 can within the

Lift shaft 3 are shifted upward and thus the elevator system 1 with the building "grow along." To move the lifting platform 11 can hereby

Anchors 19 (shown only very schematically) are temporarily solved, then the lifting platform 11 are raised, for example by means of a crane and, where appropriate, the support means 9 are suitably extended and finally the Lifting platform 11 are anchored in its new position in the elevator shaft 3 again.

In order to protect components of the lifting platform 11 or the assemblies mounted thereon, such as, for example, the drive machine 15 against objects falling through the elevator shaft 3, there is a component above such components to be protected

Protective roof 21 is provided, which should act as a crash deck. The protective roof 21 is supported in the illustrated example via supports 31 on a support plate 33 of the lifting platform 11 and spans over the components to be protected large parts of the cross-sectional area of the elevator shaft 3. Here, the protective cover 21 due to its geometric configuration as well as due to the choice of materials for its components is designed such that it has sufficient stability to be able to protect the underlying components to be protected against objects falling down from above, such as typically screws, tools, smaller stones etc., for example during the installation of the guide rails.

Before taking a position on details of a protective roof 21 for an elevator installation according to the invention with reference to FIG. 3, a protective roof 21 'shown in FIG. 2, as conventionally used in elevator installations, will be briefly explained.

The conventional protective roof 21 'has a planar geometry substantially over its entire surface. To a plate-like central roof construction 23 'are at the edges also plate-like plates 24' screwed. The central

Roof structure 23 'and the sheets 24' extend substantially in the same plane or in mutually parallel planes and are usually oriented horizontally. The sheets 24 'serve to at least partially bridge or close an otherwise existing gap between the central roof construction 23' and walls 4 of the elevator shaft 3.

Since protrusions, for example in the form of guide rails, retaining clips, etc., can protrude inwards in the elevator shaft 3 at some points, the metal sheets 24 'must be detached and removed from the central roof structure 23' before the lifting platform 11 together with the protective roof 21 ', for example another position within the hoistway 3 can be shifted. The loosening of the sheets 24 'and the subsequent re-attaching of the sheets 24' and in particular their precise alignment to bridge existing column, can be laborious and time consuming.

In addition, it may be difficult to design the sheets 24 'sufficiently stable so that they can withstand the considerable forces caused by falling objects. This is especially true since the sheets 24 'are supported only on their side directed towards the central roof structure 23' on one side

However, opposite sides are self-supporting. It may be necessary to make the sheets 24 'consuming, that is, they strive, for example, with reinforcing 26' equip to make them sufficiently resistant to mechanical strength.

With reference to FIG. 3, possible details of a protective roof 21 for an elevator installation 1 according to the invention will now be described.

The canopy 21 is similar to the conventional one described in FIG

Canopy 21 'a central roof construction 23. The central roof construction 23 is preferably flat and may consist essentially of one or more composite panels, for example metal panels or metal composite panels or sufficiently thick wooden panels.

Adjacent to lateral edges 30 of the roof construction 23, a flank construction 25 is provided. The flank construction 25 performs essentially the same tasks as the sheets 24 'of the conventional shown in FIG

Roof construction 23 '. However, the flank construction 25 is not made of horizontally arranged metal sheets 24 'as in the conventional protective roof 21'.

but has flank walls 27, which in their lower

End regions 28 (see enlarged in Fig. 4 (b)) are attached to the lateral edges 30 of the roof structure 23 and which protrude from there inclined to the horizontal 57 obliquely outwardly above.

As illustrated in FIG. 1, the flank walls 27 are arranged at an angle α of typically between 40 ° and 50 ° to the horizontal 57. The flank walls 27 extend up to or at least just before an adjacent side wall. 4 the elevator shaft 3 and thus close a gap that would otherwise open between the central roof construction 23 and the side wall 4.

Due to their inclined arrangement to the horizontal 57, the flank walls 27 of the flank construction 25 can protect underlying components to be protected particularly well against falling objects. As illustrated in FIG. 3 with arrows 41, 43, an object coming from above will first encounter one of the obliquely arranged flank walls 27. Since its mostly vertical fall direction occupies an acute angle with the inclined surface of the flank wall 27, the article will bounce off the flank wall 27 and move toward the center of the roof structure 23. In such an acute-angled rebounding 25 significantly lower forces are exerted on the flank construction than is the case for horizontally arranged sheets 24 ', as they were conventionally used in protective roofs 21'. In addition, an obliquely extending flank wall 27 may also be supported on an adjacent side wall 4 of the elevator shaft 3 during the impact.

Finally, with reference to FIG. 4, it will be explained how the protective roof 21 of the elevator installation 1 according to the invention and in particular its flank construction 25 can be advantageously configured in detail and thus advantageously mounted.

The flank construction 25 and its flank walls 27 may be composed of various components. In the example shown, the flank construction 25 has corner constructions 35 as well as side constructions 45.

Each of the corner structures 35 has two Eckflankenwände 37 aligned at an angle of, for example, 90 ° to each other. Each of the Eckflanken walls 37 may be formed by a flat sheet or a flat plate. At an adjacent edge 39, the two corner flank walls 37 are attached to each other, for example, welded together, glued, riveted, bolted or the like. Both corner flank walls 37 are arranged inclined to the horizontal.

A lower end region 28 of the corner flank walls 37 is bent in such a way that it extends substantially horizontally. At this lower end portion 28, each of the Eckflankenwände 37 and thus the entire corner construction 35 attached to the central roof construction 23.

For fixing a Eckbefestigungskonstruktion in the form of a reversibly releasable and fixable tongue and groove connection 29 is used for this purpose. This is shown schematically in sectional view in the enlarged section of Fig. 4 (c). In a simple embodiment, the tongue and groove connection 29 comprises a screw 47 which is screwed into the central roof construction 23, and provided in the lower bent end portion 28 of the Eckflankenwand 37 slot 49. As long as the screw 47 is not tightened, the Eckflankenwand 37 in the direction of the slot 49, that is in the direction shown by the arrow 51 toward or away from a corner 59 of the central roof structure 23, to be moved. However, in the two other orthogonal spatial directions, the tongue-and-groove joint 29 prevents movements of the corner flank wall 37. Due to this freedom of movement enabled by means of tongue and groove connection 29, the corner construction 35 can thus approach the center of the central roof construction 23 or, be moved away from this center to the outside to a corner of the elevator shaft 3. Once the corner construction 35 has been brought into a desired position, the screw 47 can be tightened and thus the tongue and groove joint 29 are fixed, so that the corner construction 35 is firmly fixed to the central roof structure 23 in all three spatial directions.

After the corner construction 35 has been attached to the central roof structure 23 in this way and brought to a desired position with its upper edges near the walls 4 of the hoistway 3 fixed there, the side structures 45 can be attached to the roof structure 23 and / or placed in a desired position. The side structures 45 can be formed, for example, with sheets or plates in their lower

End regions 28 are similar to the Eckflankenwände 37 bent and fixed by means of, for example, designed as tongue and groove joints 29 mounting structures on edges of the central roof construction 23. When released tongue and groove connection 29, the side structures 45 can be moved transversely to an adjacent edge 30 of the central roof structure in a direction indicated by the arrow 53 and thus towards adjacent side walls 4 of the Elevator shaft 3 are relocated. In this case, the side structures 45 can preferably be displaced outwardly so far that their self-supporting edge regions 32 arranged opposite the lower end regions 28 abut the side walls 4 of the elevator shaft 3.

For the sake of completeness, it should be noted that FIGS. 3 and 4 also show other components of the elevator installation 1, such as a speed limiter 61, a cable cover 63 and a guide shoe cover 65, which, however, are immaterial to the understanding of the present invention.

Finally, it should be noted that terms such as "comprising," "comprising," etc., do not exclude other elements or steps, and terms such as "a" or "an" do not exclude a variety. It should also be appreciated that features or steps described with reference to any of the above embodiments may also be used in combination with other features or steps of other embodiments described above. Reference signs in the claims are not to be considered as limiting.
