Definitions

  • the object of the invention is an elevator car and an elevator, more particularly an elevator car and an elevator applicable to the transporting of people and/or of freight.
  • Elevator cars are conventionally formed to comprise a load-bearing frame structure, i.e. a car sling, which comprises a lower horizontal beam system and an upper horizontal beam system, as well as a vertical beam system of a first side and a vertical beam system of a second side, which beam systems are connected to each other so that they form a closed ring, inside which is an interior comprised in a car box fixed to the beam systems, which interior can receive goods and/or passengers for conveying them in the interior of the elevator car.
  • the car box has been essentially fully inside the aforementioned ring.
  • the outer surface of the roof of the elevator car is generally formed from plates that are firmly and rigidly supported on the upper horizontal beam system.
  • the roof panel can be a single-piece or multi-piece roof panel, and the bottom surface of it forms a planar surface bounding the interior of the car.
  • the roof panel is generally quite thin in terms of its thickness, e.g. a plate-type structure less than 50 mm thick, into which luminaires are integrated.
  • the roof panel is generally fixed into its position with an openable locking, which can be opened from inside the car for taking the roof panel down.
  • the roof panel structure has increased the total thickness of the roof structure by the amount of its own thickness plus possible fastening clearances. Also, in connection with the aforementioned solutions according to prior art, the use of this type of conventional method produces a rather thick roof entity.
  • one problem with solutions according to prior art, among others, can be considered to be non-optimal space usage. More particularly the roof structure of an elevator car has not been optimized as an entity sufficiently from the standpoint of space usage. All the essential factors have not been simultaneously taken into account to an adequate extent, more particularly the placement of structures and components external to the elevator car, the space-efficiency and durable construction of the beam system of the frame structure, and also, importantly, the placement of structures and components internal to the elevator car. Thus the overall structure of the roof has not been optimal, more particularly the free vertical interior of the elevator car and the free vertical space of the part of the hoistway above the elevator car have not been maximal.
  • Reducing or increasing the total thickness of the structure of the roof thus directly affects the size of the interior of the elevator car or, correspondingly, the size of the safety space that is above the elevator car between the roof of the car and the roof of the elevator hoistway.
  • Each millimeter by which the interior of an elevator car can be increased is important.
  • the aim of the invention is to eliminate, among others, the aforementioned drawbacks of prior-art solutions. More particularly the aim of the invention is to produce an elevator, the roof structure of the elevator car of which is extremely compact in the vertical direction. The aim of the invention is further to produce one or more of the following advantages, among others:
  • the invention is based on the concept that the space efficiency of an elevator car of an elevator can be increased if the elevator car is formed to comprise a frame structure, the roof beam of which is a downward-opening, elongated, channel profile member, the width of the cross-sectional profile of which is essentially larger than the height.
  • a rigid structure can be achieved, which has an interior that can be utilized for functions affecting the interior of the car, such as for creating air ducting for ventilation or for accommodating a light source and/or a reflective surface for the lighting.
  • With a broad structure it is also possible to simply form a part of the standing surface of the roof.
  • the elevator car comprises a free interior for receiving a load, e.g. for receiving passengers and/or freight, which interior is bounded by at least the walls, roof, floor and preferably also door arrangement comprised in the elevator car, and a frame structure, which frame structure comprises a horizontal elongated rigid roof beam in connection with the roof of the elevator car, which roof beam extends across the roof of the car above the interior, and which roof beam is an elongated channel profile member, which has essentially the same continuous cross-sectional profile in the longitudinal direction.
  • the roof beam is a downward-opening, elongated, channel profile member, the width of the cross-sectional profile of which is essentially larger than the height.
  • the interior of the channel profile member is configured to function as a space for one or more functions of the car affecting the conditions of the interior of the elevator car, including lighting.
  • the interior of a roof beam can be utilized and a shallow structure can be formed over the center area of the interior of the car, which structure delivers a number of functions, the structures on the sides of which structure can be formed to be simple and thin.
  • the roof beam is a downward-opening channel profile member, which has an interior, and in connection with the roof of the elevator car is one or more luminaires, which are arranged to illuminate the interior of the elevator car, and the structure of which luminaire, more particularly the light source of the luminaire and/or the reflector of the luminaire, is at least partly, preferably mostly, more preferably wholly, in the interior of the channel profile member. In this way the whole cross-section of the roof of the elevator car can be efficiently utilized in both the transverse direction and the vertical direction.
  • the channel profile member forms a part of the inner wall of the casing, into which casing a luminaire is disposed. In this way efficient use of the area of the beam is achieved.
  • the width/height ratio of the cross-sectional profile is preferably at least 4. In this way the beam can be formed to be shallow, when the interior of it is of sufficient volume for accommodating other functions. Nevertheless, it is advantageous that the width/height ratio is less than 20, more preferably less than 10.
  • the height of the cross-sectional profile is preferably 20-60 mm, preferably 25-50 mm. In this way the total thickness of the roof of the elevator car is shallow, however being rigid owing to the wide channel shape.
  • a roof plate of the elevator car Preferably beside the roof beam, preferably on both sides of the roof beam, is a roof plate of the elevator car, the top surface of which forms a part of the visible top surface of the elevator car and/or the bottom surface of which forms a part of the visible bottom surface of the roof bounding the free interior of the elevator car.
  • the structure is advantageous because the roof plates beside the shallow roof beam do not increase the total thickness essentially or at all. It is advantageous to support the roof plates in the vertical direction on the aforementioned roof beam.
  • the thickness of the roof plates is preferably smaller than the height of the roof beam, preferably at most 20 mm.
  • the base of the channel profile member forms an elongated ridge extending upwards from the roof of the elevator car.
  • the ridge preferably tapers upwards. In this way the tripping hazard caused is minor.
  • the ridge comprises a flat top surface.
  • the elevator car comprises suspension means of the elevator car separate from the roof, in which case especially large forces are not exerted on the roof structure.
  • the means are on the bottom part of the elevator car, preferably they comprise a diverting pulley system, most preferably a diverting pulley system that is arranged to guide the hoisting roping descending from above to the elevator car to pass under the elevator car and back upwards.
  • the roof beam system bears less load than if the supporting were supported directly on the roof beam.
  • said functions of the car affecting the conditions of the interior of the elevator car include ventilation.
  • the elevator car comprises a ventilation arrangement, wherein the air is conducted between the interior of the car and the space outside the car, more particularly between the interior of the car and the elevator hoistway, via the interior of the channel profile member.
  • the interior of the channel can be utilized for an air-conditioning function.
  • the elevator car comprises ducting between the interior of the car and the space outside the elevator car (elevator hoistway), which ducting comprises an air duct leading from the space outside the car into the interior of the channel profile member and a duct leading from the interior of the channel profile member into the interior of the elevator car, for conducting air between the interior of the car and the space outside the car (elevator hoistway) via the interior of the channel, and preferably a ventilation device for transferring air in the air ducting.
  • Noise dampers such as elastic members, e.g. of foamed polymer, can be installed in the interior of the channel profile member.
  • the roof beam is a downward-opening, elongated, channel profile member, which has an interior, which is bounded from above by the base of the channel profile member, and which interior in the lateral direction is bounded by the side walls of the channel profile member (between which side walls the interior of the channel is, and which side walls extend from the base downwards at a horizontal distance from each other).
  • the base comprises one or more horizontal sections. The horizontal section (s) can each form a part of the visible top surface of the elevator car.
  • the channel profile member comprises a profile section extending from each side wall of the channel, from the bottom part of the side wall, towards the side, away from the interior of the channel profile member.
  • the structure of the roof profile member further stiffens in relation to vertical bending, the second moment of area significantly increasing as more cross-sectional area of the profile section is brought to a distance from the neutral axis.
  • a roof plate of the elevator car is preferably fitted, beside the channel profile member.
  • the base of the channel profile member comprises horizontal sections, and an elongated depression connecting them, which depression forms an elongated ridge on its opposite side (separating upwards from the horizontal sections).
  • the ridge further stiffens the beam in relation to bending and torsion.
  • the structure of the ridge/depression is such that the walls, which connect the horizontal section, of the ridge/depression extend upwards from the aforementioned horizontal sections.
  • the channel profile member therefore comprises in its base a downward opening bottom channel.
  • the horizontal section of the ridge forms a part of the visible top surface of the elevator car.
  • the horizontal top surface of the ridge is at most 150 mm in width, preferably at most 100 mm, preferably approx. 30-50 mm.
  • the transverse width of the ridge is preferably less than 200 mm, more preferably less than 150 mm, preferably approx. 40-120 mm (bevels can be created in the ridge, with which the width of the top surface can be limited to lower than this, which bevels at the same time reduce the tripping hazard).
  • each roof plate forms a part of the visible top surface of the elevator car and the horizontal top surface of the ridge is above the plane of the top surfaces of the aforementioned roof plates.
  • a cover plate which forms a part of the visible bottom surface of the roof bounding the free interior of the elevator car, which cover plate is below the interior of the channel profile member.
  • the cover plate comprises an area via which the luminaire illuminates the interior of the car, or the structure of the luminaire can extend through the cover plate (e.g. a recessed luminaire). In this way the cover plate can tightly cover the non-aesthetic parts of the utilized roof structure.
  • the top surface of the base of the channel profile member forms a part of the visible top surface of the elevator car.
  • the distance between the side walls of the channel profile member is at least 150 mm.
  • its width is advantageous for producing rigidity and the volume of its interior is sufficient for accommodating additional functions without an increase in thickness.
  • the channel profile member is bent from sheet.
  • the channel profile member is bent from sheet of even thickness, the thickness of which is between 2-4 mm, preferably 2.5-3.5 mm.

  • the channel profile member is fabricated from an integral piece.
  • the channel profile member is of metal.
  • the frame structure comprises the aforementioned roof beam, the vertical beams of a first side and of a second side, and a floor beam system, which are connected to each other such that each of them forms a part of a ring-like frame structure, inside which is the interior of the elevator car.

  • inventive content may also consist of several separate inventions, especially if the invention is considered in the light of expressions or implicit sub-tasks or from the point of view of advantages or categories of advantages achieved. In this case, some of the attributes contained in the claims below may be superfluous from the point of view of separate inventive concepts.
  • the features of the various embodiments of the invention can be applied within the framework of the basic inventive concept in conjunction with other embodiments.
  • the additional features mentioned by each preceding embodiment can also singly and separately from the other embodiments form a separate invention.
  • Fig. 1 presents an elevator according to the invention, which elevator comprises an elevator hoistway S, and an elevator car 1 according to the invention arranged to move in the elevator hoistway, which elevator car 1 comprises an interior I, which is bounded by the walls, roof, floor and door arrangement of the elevator car.
  • the elevator car is moved with a hoisting machine M via hoisting ropes 20.
  • the elevator car 1 comprises a frame structure F (suggestively presented), which comprises one horizontal, elongated roof beam 2 in connection with the roof R of the elevator car 1, and the vertical beams 3 of a first side and a second side, and a floor beam system 4, which are rigidly connected to each other such that each of them forms a part of a ring-like frame structure F, on the inside of which is the interior I of the elevator car.
  • the roof beam 2 is in connection with the roof, i.e. it is integrated to be a part of the structure of the roof so that it forms a part of the roof structure bounding the interior.
  • a preferred structure of the frame structure F (2,3,4,5,6) is presented in Fig. 2 .
  • the frame structure F comprises one horizontal elongated rigid roof beam 2, which extends across the roof of the car above the interior I.
  • the roof beam 2 is rigidly connected to the vertical beams 3 via the joint parts 5.
  • the roof beam 2 is a downward-opening, elongated, channel profile member, which has essentially the same continuous cross-sectional profile in the longitudinal direction, and the width of its cross-sectional profile is essentially larger than the height. In this way the roof beam forms a shallow structure, which however has sufficient vertical bending rigidity owing to the large cross-sectional area.
  • the channel shaping increases vertical rigidity. Downward opening makes possible a very thin roof structure, because in this way functions of the elevator car in connection with the interior I of the car can be disposed in the interior T of the channel profile.
  • the beam 2 is preferably according to that presented in Fig. 3a .
  • the roof structure is in this case preferably according to Fig. 3c .

  • the beam is further preferably such that the height of its cross-sectional profile is 20-60 mm, preferably 25-50 mm.
  • the distance between the side walls 21 of the channel formed by the beam 2, which is thus a channel profile member, is preferably at least 150 mm.
  • the width is not very great, but instead it is advantageous that the width/height ratio is less than 20, more preferably less than 10, because widening of the member, although it would make additional space between the walls, would take the walls 21 away from the center area of the elevator car, among other things increasing the cross-sectional area of the beam and the material belonging to it, increasing the rigidity, however, only slightly.
  • the side walls 21 are preferably vertical. In the dimensions it is advantageous that the distance between the side walls 21, i.e. the width of the interior of the channel, is less than 60 mm, more preferably at most 40 mm.

  • the downward opening channel profile member 2 comprises a sort of a downward opening bottom channel, which forms a ridge p.
  • the ridge p increases the second moment of area of the channel profile member effectively stiffening the structure against vertical bending and torsion.
  • this additional stiffening (the ridge p) can be formed to be narrow, in which case it does not essentially reduce the top clearance of the elevator, in particular it can be formed to be so narrow that it is not pleasant to stand on it, in which case it does not form a higher-level flat area that can be stood upon.

  • the structure of each roof plate 8 continues in the lateral direction to outside the figure towards the edges of the elevator car, and there can be a number of them side-by-side, continuing up to the edges of the elevator car, or if it is desired the roof plate presented can be large and can extend up to the edge.
  • the top surface of each aforementioned roof plate 8 forms a part of the visible top surface of the elevator car 1 and the bottom surface of it forms a part of the visible bottom surface of the roof R bounding the free interior I of the elevator car 1.
  • the roof plate 8 is preferably supported in the vertical direction on the roof beam 2.
  • the channel profile member preferably comprises a profile section, visible in the figures, extending from each side wall 21, from the bottom part of the side wall, towards the side, away from the interior T of the channel profile member, on top of which profile section, resting on its top surface, a roof plate of the elevator car is fitted, beside the channel profile member.
  • the top surfaces of the roof plates 8 are preferably standing platforms, i.e. they comprise a standing area on their top surface, immediately above which standing area is a space free of the parts of the elevator car 1 and free of the ropes of the elevator, for enabling standing on top of the aforementioned standing area at least when the elevator car 1 is situated at a distance from the top end of the elevator hoistway S.
  • top surfaces of the roof plates 8 are preferably essentially on the same plane with the horizontal sections 22 of the base of the channel profile member. In this way a step to the top surface of the roof does not form at this point and the safety space above the roof is high over a wide area.
  • the frame structure F is a load-bearing frame structure, and is thus suited to bearing most of the forces exerted on the elevator car 1.
  • the frame structure F as an entity, is preferably according to that presented in Fig. 2 .
  • Wall paneling, a floor and/or roof paneling, which is/are not presented in Fig. 2 is/are intended to be fixed to the frame structures 2,3,4,5,6 presented. When desired, they can be configured to participate to some extent in stiffening the overall structure.
  • the roof beam 2 in its length is such that it essentially covers the length of the elevator car (as measured in the longitudinal direction of the roof beam), i.e. at least 80% of the length of the elevator car.
  • the beam can be made to be slightly shorter than the length of the car.
  • the profile element continues essentially the same, i.e. being able to comprise a small amount of holds or bends for a fixing.
  • the cross-sectional profile continues as the same preferably for essentially the whole length of the beam, preferably for at least 80% of the length of the beam. For example, for the butt end fixings or for the holes 40, some material can be removed at these points in the profile.
  • the roof beam 2 extends across the roof of the car above the center area of the interior I, at a horizontal distance from the wall/door panel that bounds the interior (when viewing the vertical projection) on the sides of said center area.
  • the beam 2 is preferably centered at least such that the horizontal distance of the beam from the walls of the elevator car in the direction of the beam differ from each other by at most 30%.
  • the beam is in the direction of two wall/door panels that bound the interior on opposite sides of the elevator car.
  • T data lines and/or electric lines can, in addition or alternatively, be led, e.g. for conducting electricity and/or data to devices on the roof of the elevator car or in connection with the roof from the control unit of the elevator car or from an electricity source regardless of the more precise location of the devices.
  • the devices can be a fan or a luminaire and/or for service-drive control means (not presented) for the elevator car.
