Definitions

  • the invention relates to a safety system for a lift with a car apron according to the preamble of claim 1.
  • Such safety systems with a car apron provide protection in case passengers have to be released from a car stuck in the area of a floor opening, at a distance from the inherent stopping position. In such a case, a more or less large gap between the lower edge of the car floor and the top of the floor ceiling opens up.
  • the people to be evacuated will usually sit on the car floor and then let their legs out of the car until they come to a stop on the floor. There is now the danger that these people come in reserve and crash through the gap between the bottom of the car and the top of the floor ceiling in the shaft.
  • the car apron of such a safety system must have a considerable length in the vertical direction.
  • the relevant standards usually require a length of not less than 750 mm.
  • the DE 203 13 911 U1 a designed in the manner of a scissor lattice, in vertika-Ler direction telescopic grid before car apron.
  • a grating is not only expensive, but also problematic among points of stability because numerous pivot points are to be realized.
  • the grid which can not be supported backwards (seen from the shaft door opening) in boxwise direction, must be very rigid in itself. Sufficiently rigid, so as not to give in, even if at its lowest extremity large forces acting approximately horizontally in the direction of the nest attack, as in the worst case occur when a person falls in the direction of the bay against the lowest end of the grid.
  • relatively heavy and stable structures are required, which not only unnecessarily limit the payload of the car, but also expensive to wear and only with considerable effort to use, in particular to catch up again.
  • This construction has two disadvantages. Firstly, the apron is not blocked in its protective position. That is, it can not be ruled out that the skirt is pushed aside by the action of stronger forces acting approximately horizontally in the shaft direction. For example, in situations where a passenger tries to descend from a car stuck high above the floor ceiling onto the floor, thereby losing his balance and falling backwards against the apron in the direction of the shaft.
  • This car scooter is formed to consist of two sheet-like elements which are hinged together at the extreme ends of their opposite horizontal edges by means of hinges.
  • the first lowermost plate Is provided with a lower transverse strut, which in turn is connected by means of longitudinal struts with a four-bar linkage.
  • the second, the car floor near sheet is pivotally hinged to the car in an area below the car door threshold.
  • the construction is designed in such a way that the two panels forming the actual car apron do not come to rest either completely or approximately in a protective position neither in a plane nor parallel to one another in adjacent planes.
  • the four-bar linkage used here ensures that the two plates forming the actual car apron can not "make long", but always have a certain angular position relative to one another and thus ensure that the plates can be folded together when the apron touches the shaft bottom.
  • This construction has different nights. On the one hand leads to a penetration permitting opening of this construction to the dangers.
  • this construction is not completely harmless because it is not locked and in particular is not self-locking. That's crucial. Because it is again so that a person who has emerged from the car with the feet on the floor during the emergency exit and at this moment loses its balance and falls unhappy back against the car apron, the car apron can push aside a considerable amount aside ,
  • this construction although the actual car apron plates forming folds claimed considerable space under the car floor. This is because the inboard tie bar between the four-bar linkage and the bottom plate of the car apron is approximately the same length as the two panels of the car apron in its unfolded position. Therefore, the construction requires significantly more space under the car floor, as required by the two folded plates per se.
  • the invention is based on the object to provide a safety system with a movable car apron, which offers improved protection in protection position and opens the possibility to have to keep free for the rest position only less area under the car.
  • the safety system has means by means of which the foldable skirt elements can be locked in their protective position such that they neither move relative to one another by forces acting on one or more apron elements from the outside and in the baywise, substantially horizontal direction, nor pivoted together in the bayward direction
  • a guide means guiding the folding movement of the skirt elements is designed and acts on one of the skirt elements such that it simultaneously acts as a locking means in the protective position by locking the skirt elements in their protective position against each other and at the same time against joint pivoting in the shaftwise direction, wherein, based on the intended mounted state, the axis about which at least one locking means is pivotally mounted on one of the skirt elements, lies below the axis around which the fahrko Rb (2004)e apron element is pivotally hinged to the car, and above the axis, which connects the apron elements foldable relative to each other.
  • Verrlegelungsmittel are designed self-locking, d. H. an attacking in the opening direction force locks the locking means against opening, so that the force acting in the opening direction force can be arbitrarily large, without fear that the lock will yield (as long as no Bautellzerpara occurs).
  • the guide means which guide the folding movements of the skirt elements are designed and engage one of the skirt elements in such a way that they act as a locking means in the protective position by locking the skirt elements in their protective position against each other and at the same time against joint pivoting in the slotwise direction.
  • Such a design leads to a substantial simplification. It requires no additional locking means more.
  • the axis about which the guide or locking means are pivotally mounted on one of the skirt elements is, seen in the vertical direction, between the axis about which the car next apron element is pivotally hinged to the car, and the axis which the skirt elements connects relative to each other.
  • Such an axial position allows in a particularly simple manner an effective, because preferably self-locking locking the skirt elements.
  • the skirt elements are hinged to each other so that on a skirt element, the common pivot axis is disposed away from its nearest horizontal edge, so that the portion of this apron element which extends between the common pivot axis and the horizontal edge, forms a lever arm with respect to the common pivot axis on which the guiding or Verriegefungsstoff attack.
  • This lever arm allows a self-locking blockage of the two skirt elements.
  • the guiding and / or locking means comprise at least one pull or push rod, which is foldable in itself. This reduces the space requirement under the car in rest position, since then occupy not only the apron, but also the draft or push rods used for the construction of little space.
  • the guiding and / or locking means comprise at least one telescopic actuating member.
  • the skirt elements extend in their protective position in a plane or substantially parallel to one another along paths of directly adjacent planes, so that they form a substantially flat overall surface.
  • Such Design makes it possible to keep the gap between the car apron and the upper edge of the respective floor ceiling largely constant small. The risk of pinching is even lower than when using a skirt with a "Knlck", ie an apron whose apron elements are arranged more than slightly angularly to each other.
  • a further preferred embodiment provides that the skirt elements are held in their rest position by another Verriegelungsmiltelartart under the car floor, that they automatically pivot in the protective position and lock there when the lock of said further locking means is deactivated.
  • Such an embodiment ensures that even with sudden power outages, which have the consequence of a subsequent emergency exit of the passengers result, the apron elements are reliably placed in their protective position.
  • a monitoring device is provided, by means of which it can be detected whether the apron elements properly assume their rest position after their use and release the ride only when that is the case, so putting on is prevented.
  • the 1a shows a 2: 1 suspended in pulley traction elevator with its main components, the elevator is shown as such only schematically and is used in the representation chosen here only as an example - the invention can equally be used in quite other types of elevators, including hydraulic elevators ,
  • the elevator consists of an elevator car 1, which runs along the guide rails, not shown, the shaft 2 along.
  • a traction sheave 3 is provided, which is here, purely by way of example, designed as a drive with so-called double wrap.
  • the support cable 4 runs on one side to the cabin, is guided by pulleys 5 under the car 1 and runs on the other side back up into the shaft head, where the support cable is fixed (not shown here).
  • the support cable 4 runs from the drive to the counterweight 6, which may possibly also be suspended in a bottle (not shown here).
  • Fig. 1a The of Fig. 1a selected representation shows the situation that the car has kept unscheduled in the shaft, for example due to a power failure or damage to the traction sheave drive.
  • the car 1 is therefore only partially in front of the shaft door opening 6.
  • the passengers are released from the car by the car doors are opened manually.
  • the passengers sat in such a situation, at least if a greater difference in height to the floor floor is overcome, usually on the threshold of the car door and can then slide along the arrow P with their feet first down to the floor 7 floor.
  • the safety system which will be explained in more detail below, consists of a car apron 9 with two largely rigid apron elements 10 and 11 and the movement of these apron elements guiding elements in the form of a linkage comprising two articulated levers 12.
  • the two apron elements 10 and 11 are located here in their so-called protective position, ie they are oriented vertically, ie largely vertically running down from the floor area of the car (with minor deviations from the vertical being harmless, but full vertical orientation is desirable).
  • the two skirt elements 10, 11 are locked in their protection position - the skirt elements can not be moved relative to each other or jointly in the inward direction by forces acting from the hoistway door opening in the baywise and substantially horizontal directions on one or both of the skirt elements 10, 11 be panned. It is noteworthy that here is a self-locking lock vorltegt-attacking the said forces causes the skirt elements are held even more firmly in their protective position. In order to bring the skirt elements out of their protective position, the larger the said forces acting in the horizontal-bayward direction, the greater are the greater the forces required.
  • FIG. 1b gives a section of the Fig. 1a shown security system, namely the area in which the two skirt elements 10 and 11 are hinged together and the second skirt member 11 is hinged to the articulated lever 12.
  • first apron element 10 Shown here is a first apron element 10, which is articulated by means of the hinge 13a in the region near the threshold of the elevator car pivotally mounted on the elevator car.
  • the first skirt element 10 is largely rigid in itself.
  • this apron element is formed from a full-surface sheet, although admittedly allows certain twists, but does not yield significantly, so in itself is largely rigid.
  • this apron element can also be formed, for example, by a circumferential, substantially rigid apron element frame, which is planked or tightly covered with a suitable material, for example a plastic plate, a Kevlar fabric or thick nylon fabric or a glass fiber fabric.
  • skirt element has no larger openings which are accessible from the shaft door opening, when the skirt element is in the protective position. Any larger openings, ie openings that allow penetration of whole body parts, constitute a source of potential injury.
  • the same design options are open for the well-shaped skirt element 11 as for the first skirt element 10.
  • both skirt elements are constructed identically.
  • the skirt member 11 is articulated on the first skirt member via a hinge 13b.
  • the hinge 13b is mounted (relative to the protective position) in the vicinity of the lower horizontally oriented end edge of the first skirt member 10.
  • the hinge is attached to the further skirt element 11. This, however, at some distance from its (seen in protective position) horizontally aligned upper end edge.
  • In the vicinity of the upper horizontally oriented end edge of the other apron element 11 is articulated articulated via another hinge 13c of the articulated lever 12, which functions not only as a guide means that controls the folding and unfolding, but also as in its length (between its articulation points under the car and the skirt element 11) variable locking means.
  • lever arm H As a result of the just described type of articulation of the articulated lever, the articulation point of the articulated lever 12, based on the axis of the hinge 13b, a lever arm H.
  • the length of this lever arm H is to be dimensioned depending on the circumstances of the case.
  • the two skirt elements 10 and 11 when they are, as here, in protective position, form substantially a flat surface-by the two skirt elements parallel to each other in two immediately adjacent planes (apart from the Abweisschräge 14 am lower end of the lower protective element 11), so that they have substantially a total area form, at which even when the elevator is still moving, nothing can get caught, and ensures an approximately equal gap distance between the skirt surface and the top of each floor floor 7.
  • the Fig. 1c shows (schematically) the safety system just discussed in its rest position. Preferably, this rest position is always taken when scheduled operation expires.
  • the safety device comprises an electric holding magnet 16 mounted on an unspecified carrier. This acts (with respect to the protective position) on the lower portion 12b of the articulated lever 12 and holds it in an approximately horizontal, folded position. It is not necessary (and preferably even waived) that the security system is folded completely flat under the car floor. Rather, the security system can and should not be folded completely flat even when folded, but "applied” by a certain amount in the vertical direction. Because then there is enough space to accommodate both the first apron element 10 and the two parts 12a and 12b of the articulated lever 12 between the bottom of the car floor and the second apron element 11 and possibly also a stable support frame, d. H.
  • the buckling 12 is designed accordingly.
  • An example of its design shows the Fig. 1I - the Fig. 1i shows a section of the buckling lever 12 in the region of the joint 12c between the upper articulated lever part 12a and the lower part 12b.
  • the lower buckling work part 12b is equipped with a stop lug 12d which limits the pivoting travel of the two articulated levers 12a and 12b relative to one another. It is such that the articulated lever can only continue to buckle from the position shown here in such a way that the articulation point 12c moves upward in the direction of the arrow , It is not possible from this position to kneel the buckling so that the hinge axis 12c moves downwards, opposite to the direction of the arrow.
  • the buckling lift 12 is designed so that the longitudinal axis 12f of the buckle lever part 12b deviates by a few degrees from the longitudinal axis 12e of the upper buckling work part 12a.
  • the articulated lever is self-locking in the sense that even when high forces occur in the axial direction of the axle 12c can not be made to emigrate upward in the direction of the arrow.
  • the safety device can be unlocked, for example, by a small, possibly closable hole (closable by plugs or the like) is provided in the upper skirt member 10 at a suitable location by the means of a hook rod or other suitable tool from the floor side in the direction of the arrow the buckling lever 12 can be pulled to cause it to buckling. Then both apron elements can be brought together with the corresponding réellesmillel back to the rest position - manually or with a corresponding device.

  • Fig. 1g and 1h show the construction of the first embodiment just discussed again in three-dimensional view.
  • Fig. 2a to 2f show a second embodiment of the invention.
  • the two skirt elements 10 and 11 can be hinged together in the same way as the Fig. 1b for the previous embodiment shows.
  • Changed here are only the guiding and locking means, which are designed in the form of a pivot lever 120, which consists of two sections, namely its upper portion 120 b and its lower portion 120 a.
  • This pivot lever 120 is articulated with its lower portion 120a in the same way as before, hinged to the lower skirt member 11.
  • the upper portion 120b of the pivot lever 120 is guided horizontally displaceable in linear guides.
  • an actuating member in the form of a linear drive 121 is articulated at the lower portion 120a of the pivoting lever 120 in the second exemplary embodiment shown concretely here.
  • This linear drive 121 makes it possible to bring the skirt elements 10, 11 at any desired time from its rest position to its protective position, and vice versa.
  • This variant is therefore particularly suitable for elevator systems in which a premature opening of the shaft doors should be made, and therefore the apron must remain in protective position even during regular operation until the car anograph the lowest stop where the apron must be retracted for reasons of space .
  • the construction is, as is preferred, designed so that the linear drive, for example because its piston rod is retracted against the force of a spring, even in a power failure, ie when no supply voltage is available, the skirt elements 10, 11 automatically in its protective position bring where they lock. A locking takes place because the lower portion 120a of the pivot lever 120 is articulated on both sides. Due to this, it can not transmit compressive forces in the horizontal direction.
  • this portion 120a of the pivot lever 120 tries to go even further in a vertical orientation, if it is loaded from the outside with forces acting in the horizontal direction.
  • the linear guides are designed accordingly, the lower and upper sections of the pivoting lever will "creep", as it were, and lock automatically or, ideally, in a self-locking manner.
  • the linear guides are designed so that no seibsttätiges or self-locking locking takes place, means are used to ensure the external locking.
  • the linear drive for locking and / or provide further means (such as spring-biased locking pins which engage corresponding recesses of the pivot lever 120), which prevent the upper portion 120b of the pivot lever continue to move in the Unear Adjusten 16 and can dodge.
  • further means such as spring-biased locking pins which engage corresponding recesses of the pivot lever 120
  • Fig. 2d It is shown how the blockade can be canceled again if it is to be overflowed to the regular operating state.
  • a small, possibly closed by a stopper opening provided, can be inserted through the means of a suitable push rod, the upper part 120a of the pivot lever 120 back into its horizontal linear guides ,
  • this embodiment can also be modified to the effect that the linear drive 121 is dispensed with.
  • locking means are provided which hold the running in the linear guides end 120 b of the pivot lever 120, as long as the skirt elements are to assume their rest position.
  • the blockade is released.
  • the two skirt elements 10 and 11 fall under their own weight down, unfold and pull the portion 120 b of the pivot lever out of its linear guides, so that the skirt elements under the influence of their own weight automatically on the in Fig. 2b (For the variant with linear drive) shown intermediate position away in the of Fig. 2c swing shown and can lock there, preferably automatically or self-locking, as described above.
  • the Fig. 3a to 3f finally show a third embodiment.
  • an actuating member 1200 is used here, which is articulated at the appropriate place as the articulated lever 12 at the lower apron element articulated.
  • the two skirt elements 10 and 11 are elastically biased against each other at this point by means of a suitable torsion spring 1200a such that the two skirt elements fold automatically when the piston rod of the linear drive retracts (FIG. Fig. 3c, 3d ).
  • This actuating element 1200 is preferably a linear drive, ie a cylinder driven by an electric motor or by fluid pressure with a retractable and extendable piston or threaded rod (in the broadest sense), which ensures a corresponding actuation of the skirt elements.
  • a mechanism is provided which can extend the linear drive even in case of power failure such that it brings the apron elements in protective position and stops there locked.
  • the linear drive works, for example, against a Federspelcher that can extend the linear drive on collapse of the supply voltage to the protection position.
  • a device is additionally provided, which locks the linear drive, if no supply voltage is available, in that extended position corresponding to the protection position. This can be z. B.
  • Fig. 4a to 4c show a further, the above-described second embodiment largely corresponding example.
  • the difference here is that the lower end of the lower skirt element 11 (relative to the protective position) is provided with a roller which guides the lower end of this skirt element during unfolding, and especially when the protective position is reached, with respect to the shaft wall.
  • the lower end of the apron element 11 wedged against the shaft wall during deployment, so not pivoted to its final protective position and no Self-locking occurs.
  • such a role is especially advantageous if the car apron, z. B. because of "leading Schechtfötechnisch", should remain permanently unfolded.
