Definitions

  • the invention relates to an elevator car for an elevator according to the preamble of claim 1.
  • Elevators contain elevator cars which can be moved up and down in an elevator shaft by means of a drive unit via suspension means, for example in the form of suspension ropes or suspension belts.
  • suspension means for example in the form of suspension ropes or suspension belts.
  • balustrades on the roof of elevator cars have been known and used for a long time.
  • the balustrades comprise vertical posts and horizontal spars connecting the posts.
  • the rails can have at least one handrail, which forms the top rail.
  • ASME A17.1-2000 standard for the USA or the European standard EN81-20:2014 contain instructions with detailed specifications for the design and dimensioning of the canopy and the necessary balustrade.
  • the known balustrades are comparatively heavy and expensive.
  • balustrade is designed to protect people from falling into the cabin shaft in a simple and safe manner.
  • the elevator car for an elevator system has a balustrade arranged on a roof of the elevator car.
  • the fact that the balustrade comprises guide rail engagement means, via which the balustrade can be supported on at least one guide rail of the elevator installation, results in a number of advantages.
  • the balustrade is characterized by a high degree of stability, whereby the balustrade can be constructed from comparatively light and thin structures.
  • the support it is ensured that when horizontal forces act from the inside outwards, for example when a person leans over the balustrade or possibly falls into the balustrade from the roof, undesired yielding can be easily prevented. Elaborate, complex and costly structural measures for the stable design and attachment of the balustrade to the cabin roof can be omitted.
  • the elevator car can be moved up and down along guide rails.
  • the balustrade equipped with guide rail engagement means can be supportable on at least one of the guide rails.
  • the elevator system can also have a counterweight, which can be moved up and down in the opposite direction to the elevator car. This counterweight is also preferably guided on guide rails.
  • the balustrade it would also be conceivable for the balustrade to include guide rail engagement means, via which the balustrade can be supported on the counterweight guide rail or rails.
  • balustrade and guide rail does not have to be permanent.
  • the guide rail can also only be acted on temporarily by the guide rail intervention means, for example in certain operating phases of the elevator system (e.g. during a maintenance phase when work is being carried out on the roof).
  • a guide element is preferably attached to the balustrade as guide rail engagement means for guiding the balustrade along the at least one guide rail.
  • This guide element can act on the respective guide rail at least temporarily, in particular during a maintenance phase.
  • several guide elements can also be provided as guide rail engagement means.
  • elevator cars are guided, for example, on two guide rails that are assigned to opposite shaft walls. In such a case and if the respective widths of the gap between the cabin and the respective adjacent shaft wall are too large and a balustrade is therefore required as fall protection, it can be advantageous if the balustrade is at least temporarily on both sides is guided via guide elements on the guide rails.
  • Two guide rails for guiding the car can be provided in the elevator shaft.
  • the guide rails can preferably be arranged opposite one another on corresponding shaft walls of the elevator shaft.
  • the guide rail can be a conventional car guide rail. T-shaped metal profiles are often used for such cabin guide rails.
  • other guide rails are also conceivable for the elevator installation with the balustrade that is operatively connected to the guide rails.
  • the guide element can be a sliding guide element, via which the balustrade can be guided in a sliding manner along the respective guide rail.
  • the sliding guide element can have a structure similar to what are known as sliding guide shoes, which are already known and customary for guiding the cabin. However, the use of such sliding guide shoes on or in balustrades is completely new.
  • the sliding guide element can have a guide channel in which the guide rail or at least a guide area of the guide rail can be accommodated.
  • the guide channel preferably has a U-shape.
  • the sliding guide element can have a profile with a U-shaped cross section or can be designed as such.
  • the guide rail can be a rail profile with a T-shaped cross section.
  • other profile shapes for the guide rails are also known and used.
  • the described advantageous temporary or permanent guidance of the balustrade for support is basically suitable for all profile shapes and types.
  • the mount in the guide element for engagement with the guide rail must be adjusted accordingly.
  • the guide element is arranged on a handrail of the balustrade.
  • the guide element can be arranged on the middle, horizontal beam.
  • the guide element on vertical bar elements or even posts of the balustrade.
  • the guide rail engagement means and in particular the guide element can be used in a rigid balustrade.
  • movable balustrades can be folding balustrades, for example.
  • Foldable balustrades can be placed horizontally on the cab roof or otherwise arranged in a rest position or a folded-down position and in an active position or an erected position - be erected in a vertical position or otherwise arranged vertically - for example for maintenance work and in particular for maintenance trips .
  • Such folding balustrades are, for example, in GB 2 158 038 A , U.S. 6,543,584 , EP 2 033 927 A1 and EP 2 295 363 A1 described.
  • the elevator system 1 shows an elevator system, denoted overall by 1, for a multi-storey building.
  • the elevator system 1 contains an elevator car 2 that can be moved vertically up and down in an elevator shaft 3 for transporting people or goods to individual floors.
  • the elevator car 2 is above (not shown here; but cf. the following 2 , in which the suspension means are denoted by 7) suspension means are connected to a counterweight 4, which can be moved up and down in the opposite direction to the elevator car 2.
  • Both the elevator car 2 and the counterweight 4 are each guided on guide rails.
  • the guide rails for guiding the elevator car are denoted by 5 in this case.
  • the guide rails for the counterweight 4 are the guide rails 6.
  • the counterweight 4 is arranged on one side of the elevator car 2 .
  • a designated 10 balustrade for fall protection is arranged on the roof 2, which is in an operative connection with the guide rail 5 via a guide element 11, the structure and mode of operation of which is shown and explained in detail below.
  • the front area at the cabin door 8 and on the opposite rear no balustrade parts are necessary because of the small gap widths.
  • balustrade 10' is provided on the opposite side of the elevator car 2, on which the guide rail designated 5' for guiding the elevator car 2 is located.
  • this balustrade 10' could also be equipped with a guide element 11 (cf. 3 ).
  • the balustrade 10 described here equipped with the guide element 11 is basically suitable for all types of elevator configurations or types. Instead of the in 1 In the elevator configuration shown with the counterweight arranged on the side of the car, the novel balustrade 10 can also be used, for example, in elevator systems in which the counterweight 4 is arranged in the area of a rear side of the elevator car 2 .
  • balustrade 10 is designed as a rigid balustrade. Depending on the width of the gap, the balustrade 10 should protrude at least 70 cm, and preferably at least 110 cm, above the roof 9. However, it can also be advantageous to equip movable balustrades with guide elements. Movable balustrades of this type are used in particular in elevator systems 1 which are characterized by low headroom heights.
  • balustrade 10 is a folding balustrade.
  • the balustrade 10 is foldable, i.e. it can be moved between a folded position (as shown in 2 is shown dashed) in which the Balustrade is arranged essentially horizontally and thus parallel to the roof 9 of the elevator car 1, and an erected position (as in 1 is shown), in which the balustrade 10 is arranged essentially vertically and thus perpendicularly to the roof 9 of the elevator car 2.
  • the respective guide element 11 acts on the guide rail 5. In this position, maintenance work can be carried out on the cabin roof. During maintenance trips, the balustrade 10 is guided over the guide elements 11 on the guide rail 5, resulting in secure support. When horizontal forces are applied from the inside outwards, for example when a person on the roof presses against the balustrade, the support ensures that the balustrade 10 cannot give any further and secures the person.
  • the balustrade 10 in the folded down position corresponds to a rest position for the normal mode of the elevator system.
  • the normal mode is the operating state in which a control device of the elevator system can move the elevator car 2 within the elevator shaft 3 to any desired position, since the travel path of the elevator car in this normal state is not restricted in any way due to the balustrade being folded up into its erected position .
  • the operative connection between the foldable balustrade 10 and the guide rail 5 is therefore not permanent.
  • the guide rail 5 is acted upon by the guide element 11 associated with the balustrade only temporarily during the maintenance phase when the balustrade is erected.
  • the guide rail engagement means which is preferably designed as a sliding guide element 11, slides along the guide rail 5.
  • guide elements 11 equipped with one or more rollers to create a roller guide would also be conceivable.
  • the balustrade 10 is positioned directly at the edge 13 of the roof.
  • the guide element 11 can thus be made comparatively short.
  • the guide element 11 can be correspondingly lengthened or others constructive measures such as the installation of spacer elements are provided.
  • balustrades that can be pulled out or telescopically extended in a vertical direction are also conceivable.
  • Such movable balustrades can also be equipped with the guide elements described here.
  • balustrade 10 which forms a fall protection with respect to three sides of the elevator car 2.
  • the balustrade 5 here comprises, for example, a total of four vertical posts, with two posts each having three horizontal bars 14, 16, 17 being connected to one another.
  • the uppermost beam is a handrail 14.
  • the balustrade 10 could also have only one handrail 14 on each side and a central beam at mid-height. It would also be conceivable to provide additional vertical struts to increase the stability of the balustrade.
  • the balustrade 10 has two guide elements 11, 11 ', which engage in the respective guide rails 5, wherein in 3 for a better understanding only the left guide rail 5 is shown. As can be seen, the guide elements 11 and 11 ′ are arranged on the handrails 14 of the balustrade 10 .
  • the guide rails 5 are formed by T-shaped metal profiles.
  • the sliding guide element 11 or 11' has a guide channel 12 in which the guide rail or, more precisely, a guide area of the guide rail (i.e. a rail web of the T-shaped guide rail profile) can be accommodated.
  • the guide elements 11 are designed as separate components which are fastened to the balustrade, for example by means of screws, adhesives or other connections.
  • it is also conceivable to integrate guide elements 11 in the balustrade 10 for example by having the handrail 14 molded projections to form a guide channel 12 .
