Definitions

  • the invention relates to an elevator cabin according to the preamble of claim 1.
  • Elevator systems for transporting people and goods contain elevator cars that can move up and down vertically in an elevator shaft.
  • the cars can be moved by means of a drive unit via suspension elements, such as cables or belts.
  • balustrades In certain situations, it may be necessary for a person to access the roof of the elevator car to perform work (e.g., maintenance, inspection). For this, it is essential that people can work safely on the elevator car roof. If, for example, the gap between the car and an adjacent shaft wall is too wide, balustrades must be installed on the car roof to prevent falls. Such balustrades on elevator car roofs have been known and commonly used for quite some time.
  • regulations may require that a balustrade be installed on the roof of the elevator car, projecting sufficiently far upwards from the roof to prevent a person from falling over the edge of the roof.
  • a balustrade should project at least 70 cm or at least 110 cm above the roof, according to EN81-21.
  • the EP 1 925 581 A1 The illustration shows a pivoting balustrade in which the axis forming the pivot point for the swiveling movement is mounted with limited movement in a vertical slot. To raise the balustrade, it must be swiveled and simultaneously lifted slightly. To secure the raised position, an upward-facing recess is provided on a roof-side mounting element, into which a pin attached to the balustrade can be inserted by lowering it.
  • a disadvantage of this balustrade is that it is relatively difficult to handle and requires a certain level of skill to raise and lower.
  • balustrade When the balustrade is in a folded-down position, it should be easy to raise and reliably secured in the raised position.
  • the elevator car comprises a pivotably designed balustrade mounted on the roof of the elevator car.
  • the pivotably designed balustrade is configured such that it can be pivoted, at least partially, about a preferably fixed axis of rotation between a folded-down position, in which the balustrade can be oriented substantially horizontally at least in sections, and an upright position, in which the balustrade is oriented substantially vertically.
  • the balustrade's locking mechanism secures its position, allowing it to be locked in place via a snap-fit connection during the pivoting motion to set it up. This ensures easy handling and secure operation.
  • the locking mechanism is designed so that the balustrade is automatically fixed in its position during the pivoting motion thanks to the snap-fit connection.
  • the balustrade can consist of a lower part, fixed in relation to the elevator car, and an upper part, movable about the axis of rotation.
  • Such a two-part balustrade is particularly advantageous with regard to personal safety.
  • the present balustrade provides a certain degree of protection even in the folded-down position. This is because the lower part of the balustrade, which still projects upwards, acts as a barrier and can prevent a falling person from falling into the shaft.
  • the movable part of the balustrade in the folded-down position, being essentially horizontally oriented.
  • a stop can be arranged on the stationary part of the balustrade, against which The movable part is supported in the folded-down position.
  • the stop can be, for example, an angle bracket attached to a post of the stationary part or a horizontal angled piece.
  • balustrade with its lower, fixed section and upper, movable section, can be positioned on at least one side of the roof above the elevator car.
  • additional balustrades can be provided on the other sides of the car roof.
  • a conventional fixed balustrade with a lower height could be installed on the opposite side of the roof.
  • This second balustrade could, for instance, be the same height as the lower fixed section of the first balustrade.
  • the lower, fixed part of the balustrade can include a central, horizontal rail, and the upper, movable part can include a handrail.
  • a baseboard can also be provided in the area of the roof's upper surface.
  • the locking mechanism features a detent element that can be engaged with a means to secure the raised position. To unlock it from engagement or from a locked position, the detent element can be moved so that the means is released, allowing the balustrade to be returned to the folded-down position.
  • the detent element can therefore be movable between the aforementioned locked position and an unlocked position.
  • the locking mechanism can be a detent element that is vertically displaceable under preload within a post section associated with the fixed part of the balustrade, or it can be mounted in another way.
  • the locking mechanism can include at least one spring to generate a preload for the detent element in the locked position.
  • the detent element is preloaded into the locked position by the spring. Thanks to this preload, reliable locking can be ensured.
  • the balustrade comprises a two-part post with a lower post section that is fixed in position relative to the elevator car and an upper post section that is pivotally attached to the lower post section.
  • the balustrade has two such posts.
  • the two posts form the lateral boundaries of the balustrade and serve to attach the handrail and other rails, such as the central post, which is located approximately halfway up the balustrade.
  • the locking mechanism described above can be arranged on one of the two-part posts (or even on both posts).
  • the locking element can be mounted on the lower post section with limited vertical movement.
  • the engagement mechanism for the locking element can be located on the upper post section.
  • the lower post section can have at least one vertical slot-shaped guide for guiding the locking element.
  • the locking element can, for example, have at least one tongue-shaped guide section that can be passed through or received in the guide slot.
  • the upper post section can comprise a preferably flat, planar profile wall, the leading edge of which, facing the locking element, forms the engagement means for the locking element in the locked position.
  • engagement means can be formed by a locking hook or a locking cam.
  • the locking element includes a ramp along which the engagement device can travel during setup or pivoting to achieve the erected position of the balustrade.
  • the locking element may have a locking lug located at the front end of the ramp, facing the engagement device.
  • the actuating element can have a horizontal hand or foot gripping surface, at least in the locked position. This allows for ergonomically favorable operation of the locking mechanism to release the locked position.
  • the actuating element can be horizontally oriented, at least in the locking position. A sufficiently large force can be applied to the horizontally oriented actuating element for manual or foot operation to trigger the unlocking process.
  • the actuating element has a lever section that is freestanding for a length of at least 10 cm and is essentially horizontal, at least in the locking position.
  • the actuating element can be designed as a lever that is pivotably mounted on a post section.
  • the lever-designed actuating element interacts with the locking element in such a way that pivoting the actuating element moves the locking element into the unlocked position.
  • the locking element and/or the actuating element are designed as bent parts made of sheet metal.
  • Another aspect of the invention could be directed to an elevator with an elevator shaft and an elevator car that can move up and down therein, as described above.
  • FIG. 1 shows an elevator system, designated as 1, for a multi-story building.
  • the elevator 1 comprises an elevator shaft 11 in which an elevator car 1 can move vertically up and down to individual floors for transporting persons or goods.
  • the movement of the elevator car 1 is effected by support elements designated 13, which support the car 1 in a 2:1 suspension.
  • the support elements 13 can be one or more suspension ropes or belts.
  • Pulleys 15 are designated as deflection pulleys for forming an underslung connection, via which the cabin 1 is connected to the load-bearing elements 13.
  • the drive 14, which by way of example has a traction sheave rotatable by means of an electric motor, is attached to a shaft ceiling 17 in this case to form a machine-roomless elevator. Of course, the drive 14 could also be attached to a shaft wall 12.
  • the basic design of the elevator shown is based on the principles of other elevator types and suspension configurations, other types of elevators and other suspension configurations would also be conceivable. Except for a special balustrade 4, which is described and shown in detail below, alternatives to the one shown are possible.
  • Fig. 1 The elevator variant shown could also include elevators 1 with different suspension configurations and other elevator types.
  • Cabin 1 includes a cabin roof 2, which closes off the cabin 1 at the top. Since there is too large a gap between the shaft wall 12 and a side wall 3 of cabin 1, it is necessary to provide the aforementioned balustrade 4 on the cabin roof 2 for fall protection.
  • the balustrade 4 can be extended from a Fig. 1
  • the balustrade 4 is to be moved from its upright position to a folded-down position. The corresponding closing movement is indicated by an arrow s.
  • the balustrade 4 is designed in two parts: a lower fixed part 5 and an upper movable part 6.
  • the upper part 6 is shown in the folded-down position with dashed lines. Fig. 1 recognizable.
  • balustrade 4 is arranged or shown on the roof 2 of cabin 1.
  • cabin 1 could, of course, also have several balustrades, each assigned to one side of cabin 1.
  • additional balustrades could be designed in the same way as balustrade 4 or they could be of conventional rigid construction.
  • FIG. 2 and 3 Figure 1 shows a possible embodiment of a balustrade 4 according to the invention.
  • the lower part 5 of the balustrade 4 is firmly connected to the cabin 3.
  • the upper part 6 of the balustrade is reliably vertically aligned and secured thanks to a locking mechanism 7.
  • the locking mechanism 7 has a detent element 8 and an engagement element 9 that interacts with it, preventing the upper part 6 of the balustrade from pivoting inwards in the s-direction. Any pivoting of the upper part 6 outwards or to the opposite side is prevented by a vertical stop 33, which is attached to the lower post section 22.
  • the upper part can be pivoted about a pivot axis designated R, which runs horizontally and parallel to the roof edge 35 of the roof 2.
  • the pivoting movement s from the upright position can only be accomplished after the locking mechanism 7 has been released.
  • a detent element 8 of the locking mechanism 7 must be moved downwards in the direction of arrow e to release the locking mechanism 7.
  • the balustrade 4 has two vertical posts 18, at least in the erected position, to which horizontal rails, such as the handrail designated 19, are attached as required.
  • the posts 18 are each designed in two parts and have a lower post part 22 and an upper post part 23, which is pivotably attached to the lower post part about the axis of rotation R.
  • the upper post section 23 has a stepped locking receptacle at its lower end.
  • This locking receptacle forms an engagement means 9 for the engagement of the locking element 8.
  • the locking element 24 is a locking cam associated with the lower post section 22.
  • the locking element 8 is pressed upwards into the corresponding locking receptacle of the engagement means 9 by means of a spring 34.
  • An actuating element 24 is arranged on the locking element 8, which can be grasped by maintenance personnel or another person on the cabin roof 2. By pulling the locking element 8 downwards in the e-direction using the actuating element 24, the locking mechanism 7 is released. After unlocking, the upper part 6 of the balustrade 4 can simply be pivoted downwards in the s-direction.
  • Fig. 3 The balustrade is shown in the folded-down position. In the folded-down position, the balustrade 4 is horizontally aligned in sections.
  • the upper part 6 of the balustrade 4 must be pivoted upwards in the a-direction.
  • the locking connection automatically secures the balustrade 4 in the erected position ( Fig. 2 ).
  • FIG. 4 Figure 1 shows a pivotable balustrade 4 mounted on a roof 2, supporting an elevator car 1, according to a second embodiment.
  • the balustrade 4 has two posts 18, 18'.
  • a central rail 20 is attached to the lower post sections and is positioned approximately halfway up the balustrade.
  • the profile sections for the upper handrail sections 36 and 37 are connected via vertical profile sections to a continuous horizontal profile, which forms a lower handrail section 38 in the area of the interruption.
  • post 18 has an extension.
  • the extension is formed by a profile element 39, which connects to the upper post section 23.
  • a buffer 40 for example made of rubber or another resilient or damping material, is arranged at the free end of the extension 39.
  • the extension 39 with the buffer 40 limits any potential upward movement of the cabin and, in the raised position of the balustrade 4, defines a safety zone for persons on the cabin roof.
  • the locking mechanism 7 for securing the erected position of the balustrade 4 is in Fig. 4 A horizontal actuating element 24 is discernible, with which the locking element 8 can be moved vertically downwards to unlock it. Further design details for the configuration of the locking mechanism 7 of the second embodiment are described in the Figs. 5 to 7 removable.
  • FIG. 5 Figure 1 shows the post 18 equipped with the locking mechanism 7.
  • the actuating element 24 for actuating the locking mechanism 7 is pivotably mounted about a pivot axis R2 on the lower post section 22.
  • the lever-like actuating element 24 is positioned low enough to be operated manually or, if necessary, by maintenance personnel using their foot.
  • the length L by which the lever-like actuating element 24 projects is ideally at least 10 cm.
  • the distance H2 below which the actuating element 24 is positioned with respect to the pivot axis R for pivoting the balustrade is therefore preferably at least 10 cm.
  • the distance (H1) of the actuating element 24 to the attic or the top of the cabin should be kept small.
  • the actuating element 24 then forms an advantageous foot pedal.
  • the height H1 should be 30 cm or less.
  • the stop 32 for limiting the downward pivoting movement for the horizontal folded-down position is shown in the exemplary embodiment according to Fig. 5 created by an angled section 24.
  • This angled section 24 is integrally connected to the lower post part 22, which is made from a sheet of metal.
  • This movement of the locking element 8 is indicated by the arrow e.
  • Spring 34 pre-tensions the locking element 8 into the raised position. Thanks to spring 34, a restoring force acting in the direction of arrow f is generated, resulting in automatic locking when the balustrade is raised. The return of the actuating element 24 in the P direction also occurs under the influence of the spring.
  • the upper post part 23 is fixed in position when the locking element 8 is in the locked position.
  • the upper post part 23 is The present assembly is formed from an L-shaped angle profile, wherein the profile wall of the angle profile, designated 27, is sandwiched between the locking element 8 and a wall of the lower post section 22, which forms a stop 33, in the region of the lower profile edge.
  • a recess 41 adapted to the profile thickness of the profile wall 27, is provided in the locking element for this sandwich-like reception of the profile wall 27, which forms an engagement element.
  • the wall of the at least partially L-shaped profile facing the locking element 8, which forms the lower post section 22, forms the vertical stop 33.
  • the spring 34 which in this example is formed by a helical compression spring, is arranged diagonally in the locking element. In this way, the spring 34 reliably holds the locking element 8 in the lower post part 22.
