Definitions

  • the present invention relates to an elevator anläge with an elevator car, which has a resilient ceiling construction.
  • the optimal use of space is given high priority. Therefore, the aim is to keep the free shaft space at the upper shaft end above the cabin as small as possible.
  • the canopy is accessible for maintenance and service.
  • safety standards require a shelter of 0.6 x 0.8 x 0.5 m 3 to prevent a person from being squeezed between the cabin roof and the shaft head. This means that the distance between the maintenance area on the cabin roof and the shaft head over an area of 0.6 x 0.8 m 2 must not be less than 0.5 m when the cabin is in the uppermost accessible position.
  • WO 2008/074168 AI shows a cabin construction with which the distance between the cabin and the upper shaft end is reduced to less than 0.5 m.
  • the cabin ceiling is designed with a yield of at least 0.6 x 0.8 m 2 .
  • This cabin ceiling has a cabin ceiling part which is connected to the rest of the cabin ceiling via a perforated demolition edge.
  • This demolition edge is dimensioned so that when entering the cabin ceiling part, the demolition edge breaks and thereby lowers the cabin ceiling part in the interior of the cabin.
  • the security room is at least partially shifted into the interior of the cabin.
  • safety standards are met even if the safety distance of 0.5 m between the car and the upper shaft end is undershot.
  • the present invention has the object to develop a lift system with reduced Schachtko fraum, which is as simple and efficient to maintain.
  • the elevator installation comprises a cabin and a cabin ceiling which has at least one cabin ceiling part.
  • the cabin ceiling part is suspended by means of at least one retaining element and covers an opening of the cabin ceiling.
  • the elevator system is characterized in that the holding element exerts a magnetic force on the cabin ceiling part. This magnetic force is at least equal to the weight of the cabin ceiling part.
  • gravitational force is meant the gravitational force m * g.
  • This gravitational force also includes all weight forces of elements which are arranged on the cabin ceiling part and are at least partially carried by the holding element.
  • the magnetic force exerted by the holding element is preferably designed so that it is at least as large as the weight and an operating force acting on the cabin ceiling part.
  • an operating force is understood here, for example, an acceleration force that arises during acceleration or deceleration of the cabin and the operation of the elevator system in addition to the weight on the cabin ceiling part acts.
  • the advantage of such a lift system lies in the simple installation of the cabin ceiling part on holding elements.
  • the holding elements are arranged on the cabin roof and hold by means of a magnetic force the cabin ceiling part on the cab roof.
  • the cabin ceiling part can thus be fixed only in one step on the car roof by the cabin ceiling part is held up to the holding elements.
  • the retaining element forms a releasable connection between the car ceiling and the cabin ceiling part.
  • the connection is released from a predefinable critical release force, which is from above the Ka binendecke acts on the cabin ceiling part.
  • the critical release force is precisely and selectable setting of the critical release force, to which the cabin ceiling part is held on the cabin ceiling.
  • the number of retaining elements is freely selectable and to a certain critical triggering force at which the connection triggers adjustable.
  • the critical release force can be varied by means of holding elements of different magnetic force.
  • the critical release force is adjusted to such an extent that the connection between the cabin ceiling section and the cabin ceiling reliably releases when entering the cab ceiling section. This is the case in a weight range of about 100 to 300 N.
  • cabin ceiling part Another aspect relates to a multi-part design of the cabin ceiling part.
  • the reliability in releasing the connection between the cabin ceiling portion and the car roof may be impaired.
  • the holding elements are heavily loaded unevenly.
  • cabin ceiling parts are preferably designed in two parts from a base of 2 m 2 .
  • the cabin ceiling section can also be made in three parts or as needed from even more sections.
  • a multi-part design of the cabin ceiling part has the advantage that the weight of a person passing on it is distributed substantially uniformly on the holding elements and so when exceeding the critical release force, all connection in the holding elements are reliably solved.
  • the holding element is designed as a magnetic tape or as a magnetic element.
  • magnetic tapes are at least two magnetic tapes mounted on opposite sides of the cab ceiling part on the cab roof. It is also possible to arrange four magnetic tapes on all four sides of the cabin ceiling part on the cab roof.
  • the magnetic elements are typically commercially available cylindrical elements, square or rectangular elements. Depending on the size and magnetic strength of the magnetic elements, a plurality of these magnetic elements are arranged along the side edges of the cabin ceiling part on the cabin roof. The magnetic elements are preferably equidistantly spaced.
  • a holding element is arranged by means of an adjusting element height adjustable on the cabin roof.
  • the adjusting element is preferably designed as a set screw.
  • the holding element is suspended by means of the adjusting element on the cab roof.
  • the height of the retaining element relative to the cab roof can be regulated.
  • an adjusting element in addition to screws and pins that can be determined via a grid or clamping mechanism at different heights on the cabin roof, usable.
  • the advantage of the height adjustment of the holding elements is to adjust the holding elements so that they form an ideal contact surface with the cabin ceiling part as possible without tilting. Thus, a defined effect of a magnetic force of a holding element is ensured on the cabin ceiling part.
  • Another aspect relates to a security element which connects the cabin ceiling part with the car roof.
  • the security element keeps the cabin ceiling part after releasing the connection to a predetermined minimum height relative to the cabin interior.
  • the security element is designed as a belt, rope, cable or the like.
  • two or more security elements can be used.
  • the cabin ceiling part of each individual part is secured with at least one security element.
  • the cabin ceiling part or each individual part with two or multiple security items.
  • An advantage of this is that the cabin ceiling part does not crash uncontrollably into the interior of the cabin. This prevents possible injury to a person pushing in the cabin ceiling part and the cabin occupant.
  • Deweiteren is optionally a safety net arranged on the cabin ceiling so that by means of this a person who steps on the cabin ceiling part, is trappable and hinderable in a fall into the cabin.

  • Fig. 3 is a detail view of a suspension of the retaining element with adjusting screw for height adjustment of the retaining element.
  • FIGS. 1 a and 1 b show an elevator installation 10 with a car 1.
  • the car 1 can be moved in a shaft 6 along guide rails.
  • the elevator system typically has a counterweight, a support and propellant, on which the car 1 and the counterweight are suspended, and a drive unit, which is in operative contact with the carrying and propellant via a traction sheave.
  • guide rails NEN, counterweight, carrying and blowing agent and the drive unit in the figures la and lb not shown.
  • the cabin 1 is limited towards the top with a cabin ceiling 2.
  • the cabin ceiling 2 has an area that is designed compliant.
  • an opening in the cabin ceiling 2 is provided, which can be covered by a Kabinenst- part 3.
  • the base area of the cabin ceiling part 3 is advantageously larger than the base area of the opening in the cabin roof 2. Accordingly, there is an overlapping area in the edge region of the cabin ceiling part 3 with the region of the cabin ceiling 2 delimiting the opening.
  • the cabin ceiling part 3 is arranged below the cabin ceiling 2. This ensures that when entering the cabin ceiling part 3 selbiges is lowered into the interior of the cabin 1 and the available security space is increased with respect to the upper shaft end.
  • the cabin ceiling part 3 is held in the illustrated embodiment by eight retaining elements 4, two per side of the cabin ceiling part 3, on the cabin ceiling 2.
  • the holding elements 4 are suspended in the overlapping area to the cabin ceiling part 3 on the cabin ceiling 2.
  • the holding elements 4 are designed as elements which exert a magnetic force on the cabin ceiling part.
  • Commercially available cylindrical or rectangular magnet elements are particularly suitable for this purpose.
  • magnetic tapes can be used. The number of magnetic elements used and the magnetic force of a single magnetic element with respect to the side lengths of the cabin ceiling portion 3 and the weight of the cabin ceiling portion 3 and the operating forces acting thereon interpreted.
  • the total force of the magnetic forces of all retaining elements 4, which holds the cabin ceiling part 3 to the cabin ceiling 2 is to be such that this total force at least as large as the weight of the cabin ceiling part 3.
  • the total force is at least as large as the weight and the operating forces acting on the cabin ceiling part 3. This ensures that the cabin ceiling part 3 in operation the elevator system remains reliably arranged on the cabin ceiling 2.
  • the total force of all magnetic forces should not exceed a critical tripping force of 300 N, so that the connections of the holding elements 4 solve upon entering the cabin ceiling part 3 and the cabin ceiling part 3 falls into the interior of the cabin 1.
  • two retaining elements 4 are provided on each side to hold the cabin ceiling part 3 to the cabin ceiling. Deviating from this, a larger or smaller number of retaining elements 4 can be used on each side of the cabin ceiling part 3.
  • a holding element 4 per side is preferably used.
  • the magnetic tape is typically approximately the same length as a side length of the cabin ceiling part 3.
  • FIGS. 1a and 1b show another embodiment of the elevator installation 20 with a car 1 1, which is movable in a shaft 16.
  • the elevator installation 20 here has a security element 15.
  • the security element 15 is preferably designed as a cable, cable, belt or the like.
  • the security element 15 is designed as a belt.
  • two such security elements 15 are provided, which are arranged at a distance from one another and essentially parallel to one another.
  • the ends of the straps 15 are each attached to opposite sides of the opening on the cabin ceiling 12.
  • the cabin ceiling part 13.1 is suspended in each case in a loop of the straps 15.

  • the security element 15 holds the cabin ceiling part 13 even after the release of the connections of the holding elements 14 with respect to the interior of the cabin 1 1 at a predetermined height. This ensures that the cabin ceiling portion 13.1 does not crash on passengers already in the car 1 1 and possibly injured.
  • a security element 15 In a rest position of the cabin ceiling part 13. 1, i. when the cabin ceiling part 13.1 is held by the holding elements 14 on the car ceiling 12, a security element 15 is in an unloaded state. Accordingly, a part of the security element 15 rests as a loop on the cabin ceiling part 13.1. During operation of the elevator installation 20, vibrations may occur which are transmitted to these loops. This can lead to an additional operating force acting on the cab ceiling part 13.1. This is disadvantageous in that this additional force can lead to a spontaneous unwanted release of the compounds on the holding elements 14.
  • This negative effect can be avoided by holding a freely resting loop on the cabin ceiling part 13.1 by means of a cotter pin 18 or another suitable fastening element. Alternatively, this loop is also fastened to the cabin roof 12.
