Description

Repellent door guidance

The invention relates to a guide rail for a lift according to the preamble of claim 1, a guide rail system based thereon, an elevator door arrangement equipped therewith and a lift equipped therewith.

Lifts are equipped with regularly automatically opening and closing elevator shaft doors and elevator car doors. These require the guidance. The door panels of these elevator doors are regularly suspended and guided on their upper side on a shaft side above the door lintel mounted door guide. On the floor side, in addition, guide rails in the form of door sills, which are generally embedded in the cabin floor and floor floor, are used. The elevator doors are guided in guide grooves of these thresholds. The door sills are arranged openly accessible with their guide sections or grooves and are largely in one plane with the O _* berfläche of the cabin floor or floor. The guide rails and their guide grooves therefore easily become dirty, so that it can quickly interfere with the operation of the doors, that can lead to jamming of the doors. Moreover, such thresholds do not allow to lead the floor covering of the cabin or the floor to under the doors, which is desirable not only for aesthetic reasons, but also facilitates the care of the floor.

It is known, in particular, to attach the lower guides of elevator doors to a protected location, such that the guide sections are arranged in the area of the elevator shaft and thus are not readily accessible, that is, less susceptible to soiling. Such bottom guide rails are commonly referred to as "hidden sleepers".

Such a guide is known, for example, from EP 0 708 052 A2. This document describes an elevator car, in the bottom of which, below the surface of the floor covering, a guide rail is embedded. The opening of the guide portion facing the opposite shaft wall. In this guide rail, the one end of guide shoes is movably guided, the other end is fixed to the underside of the car door, thus leading the car door. Although the Führungsabsclmitt partially covered, but inevitably remains a more or less large slot free, which allows a back and forth of the guide shoes when opening and closing the door.

The automatic opening and closing of the elevator car and elevator shaft doors, which is today standard, is a process that takes some time. For safety reasons, it is forbidden to start the elevator car when the lift doors are not fully closed yet. In order to shorten the transport time, however, it is often desirable that the opening of the car and the shaft door can be started even before the elevator car has reached its final, to be approached in slow motion stop position on a shaft door, d. H. A leading door opening poses problems in terms of safety because during the leading door opening, at least parts of the door openings are temporarily accessible, resulting in an increased risk of accidents.

In the case of the design for a hidden threshold known from EP 0 708 052 A2, a leading door opening is not possible for safety reasons. In such a construction, for example, when opening the shaft door when landing from above a landing door cabin first be started when the bottom of the cabin, the shaft door side facing lower guide has already come to lie completely below the floor floor, ie the elevator car must be practical the final position achieved. For as long as this is not the case, it can not be ruled out that any object (such as the tip of an umbrella) or even a body part (such as a shoe or toe) gets caught in the portion of the guide rail already released by the opening doors, ie via the opening, which is left free in the guide rail for the engagement of the guide rail, penetrates into the interior of the guide rail, and then clamped or even sheared by the further lowering elevator car between the elevator car and the edge of the floor ceiling.

The invention is therefore based on the object to provide a guide rail which is suitable as a concealed door guide for an elevator and which minimizes the security risk emanating from the guide rail when the elevator door is open and the elevator car is moving.

This object is achieved in that the guide rail (when viewed in a position corresponding to their mounting position) in the region of the opening, via which the guide shoes can engage in the guide rail, has a deflector. During operation, such a deflector deflects a foreign body from the region of the opening, via which the guide shoes engage in the guide rail, when the elevator car moves in a specific direction.

Preferably, the guide rail according to the invention is designed so that it can be used both as floor and as a ceiling-side rail for supporting and / or guiding the door panels.

The invention is further based on the object to provide a guide rail system, which can be realized in a variety of dimensions with a few pre-assembled items in a simple way concealed Sicherheitssträführungen for a variety of elevator door assemblies (one-sided or multi-sided opening and closing, etc.).

This object is achieved by a guide rail system consisting of a guide rail with the profiled body according to the invention, and, if necessary, individually or as a whole so that Binding components, namely a skirt and a cover solved, preferably as a further system elements in addition to a guide surface bearing profile and a final profile added.

Finally, the invention is further based on the object to provide an elevator with a concealed door guide, which allows, at least at individual stops, in a simple manner, a leading door opening.

This object is achieved in that at least one elevator door assembly whose guide rail is temporarily accessible by the leading opening of another elevator door assembly is equipped with the guide rail according to the invention.

In the following an exemplary embodiment of the invention will be explained in more detail with reference to drawings. Show it:

Fig. 1: winen cross-section through an elevator door assembly using the guide rail according to the invention;

FIG. 2a is a side view of an elevator door assembly using the guide rail according to the invention; FIG.

FIG. 2b shows a side view of an elevator door arrangement comparable with FIG. 2a but consisting of two counter-actuated door panels, which uses the guide rail according to the invention; FIG.

3 shows a detailed view of a first embodiment of the guide rail according to the invention;

4 shows a detailed view of a second embodiment of the guide rail according to the invention, intended in particular for use in the lintel area; 5 shows a detailed view of a third embodiment of the guide rail according to the invention;

6 shows a detailed view of a fourth embodiment of the guide rail according to the invention.

The diagrammatically attached FIG. 2b shows an elevator door arrangement for a shaft door which, at a stop of an elevator car, gives access to the elevator shaft or the elevator car, not shown, therein. An elevator door arrangement for a car door looks exactly the same, which is why the following statements apply mutatis mutandis to a car door.

The door assembly consists of two in opposite directions opening and closing door panels 1. The two door panels are mounted on its upper side in a conventional manner in a guide rail and are guided and carried by this, which is not shown here. Each of the door panels 1 carries at least one arm-like guide shoe 2, which is equipped at its free end with an unspecified sliding element and is guided on the bottom side in a guide rail according to the invention.

FIG. 2a shows a comparable elevator door arrangement, which differs from that according to FIG. 2b only in that only a single door panel is used here.

FIG. 1 shows a section through the center of the door opening shown in FIG. 2 with the door closed. To recognize is floor ceiling 4, which carries a complete floor covering 5, such as a covering of stone slabs, parquet or carpet.

The guide rail consists in this embodiment of an integrally formed as a bent part of sheet metal, especially steel profile body 6. Several of these profile body 6 can be arranged in alignment one behind the other, about to produce a guide for particularly wide doors (not shown here). In this case, it makes sense in the hollow, here approximately triangular cross-section of a correspondingly shaped core to be able to insert the individual profile body 6 in alignment with each other and so to avoid any alignment problems. Although the single profile body 6 is preferably to be made in one piece, it can of course also consist of several separate components, such as (not shown) from a profile which carries the guide section to be discussed in more detail and another adjacent profile to be attached, which will also be discussed later Deflector wears.

The profile body 6 of the guide rail used here as the lower guide rail carries a guide portion in the manner of an upward, door panel open towards gutter. In this channel can from the top at its end with a (unspecified) sliding body equipped guide shoes 2 engage, which in turn are attached to the door panels 1 and lead them. The guide shoes can engage in this embodiment directly from outside the guide rail in the guide portion, d. H. without that they encompass a wall portion of the guide rail from outside to inside. The guide shoes are guided through their sliding body through the side walls of the channel. Preferably, the guide section carried by the profile body and the fit between it and the slider are dimensioned so that the door panels are guided smoothly and thereby unwanted vibrations or even deflections of the door panels (for example, by the burden on the door panel leaning people) halt is offered.

Fig. 3 shows the profile body 6 used in Fig. 1, 2a and 2b in its details. The profile body 6 has two sections 6b and 6c, by means of which the Profilkorper 6 can be screwed directly or indirectly to the building or the elevator car. Also a wall in the building is possible.

The profiled body 6 carries the previously mentioned guide section 6a, whose one guide surface is formed by the section 6h of the profiled body, while the other guide surface 7a is preferably formed either by the profile 7 or a section of the skirt 3 (see Fig. 1) both can be attached to the flange 6e of the profile body. Of course, instead of the second guide surface on the profile body 6 may be formed. Here, the interchangeability of the guide shoes or their repair (For example, the renewal of the provided at its end slider) in that the channel-like guide portion can be opened by removing the door apron 3 and / or the profile 7, simplified. Together with the guide rail guide shoes can be used in a largely arbitrary position, quantity, curvature and angulation.

The Profilkorper is equipped with a leg 6d, which forms a conclusion for the front edge of the floor covering 5, which extends to below the door panels. The end leg 6d not only provides aesthetic benefits, but effectively protects the front edge of the floor covering from damage. The leg 6d is preferably formed on the profile body, but can, if the greater installation effort is not spared, also be a separate component. In the latter case, it is favorable to design the profile body 6 and the leg 6d in such a way that the leg 6d can be preassembled on the profile body 6.

The leg 6d provides, possibly also together with the flange 6e, the possibility of a covering element 8 to be mounted in the area which is not traveled by the guide shoes 2 of the door panels 1 when opening and closing the doors, for example by means of countersunk sheet metal or Screws that are screwed into the legs 6d and / or 6e. This results in a total of a very flexible system of the Profilkorper 6 and the need to be attached to him components, consisting of the guide profile 7, the cover 8 and the skirt 3 and possibly the end leg 6d. The versatility of this system can be further increased by the Profilkorper is dimensioned so that it can also be optionally used to hang door panels, preferably by means of appropriate trolleys, and lead, d. h., That the profile body can then be used as the upper door guide.

In a leading door opening, ie an opening of the elevator shaft and elevator car doors just before the elevator car has reached its final stop position, the lower guide rail of the car door for those waiting on the floor in front of the landing door people accessible when the cabin comes in from above, while the The lower guide rail of the shaft door is accessible to the cabin occupants when the car arrives from below into the stop.

In the course of the leading door opening while the area covered by the cover 8 between the doors is first released, see. for example Fig. 2b. As long as only the area covered by the cover 8 is released, accidents caused by the guide rail due to the leading door opening are practically eliminated. As the doors continue to open, the area of the guide rail, which is no longer protected by the cover 8, is also accessible, ie. H. in which the opening 6f (see Fig. 3, opening indicated there by dashed lines), over which the or the guide shoes engage in the guide rails, is exposed.

The profile body 6 is, viewed in the properly mounted position, above its guide portion 6a, d. H. in the region of the opening 6f, over which the guide shoes engage in the guide rail, equipped with a deflector 6g. This deflector is designed in such a way that usually a foreign object penetrating into the guide section 6a through the opening 6f is also pressed out of the guide rail, which causes the elevator car to move in a specific direction. In any case, it is impossible with practically sufficient certainty that a foreign body can move into the guide rail by a movement in the horizontal direction so that it is severely clamped or sheared off.

To fulfill this function, the deflector 6f can be designed in very different ways. For example, the first embodiment shown in FIGS. 1 to 3 uses a deflector which is designed as a straight discharge claw 6 g. However, the deflections can, as shown in FIG. 6, also be performed crowned or otherwise with a curved or curved surface, as long as it is designed so that the required function is fulfilled.

Possibly provided in this slope 6g for assembly purposes breakthroughs, as shown in FIG. 3, are preferably closed before startup by stable, captive caps o. Ä. The deflector, here the slope 6g, extends from the shaft side outer side of the profile body, which is formed here by the end leg 6d for the floor covering and the flange 6e or the profile attached thereto 7, 3 or 8, to approximately the (in the horizontal direction) lowest point of the guide rail from the outside Straight way can be achieved. The chamfered surface 6g is here inclined by about 25 ° with respect to the vertical axis of the shaft, ie with respect to the direction of travel of the elevator car. If the slope is curved, an average inclination between about 25 ° to 30 ° is sufficient.

The guide rail is preferably dimensioned such that the inside width "X", ie the smallest width of the opening 6f, is only slightly larger than that required for use in the guide rail on the area enclosed by the guide rail on three sides With the guide rail provided guide shoes 2 to let pass unhindered, because with decreasing "X" decreases the risk of (too deep) penetration of foreign bodies, since the opening on which an access can be very narrow.

4 shows a second exemplary embodiment of the guide rail according to the invention. This is intended in particular as a fall-side Fülirungsschiene for guiding and suspending the door panels at its top.

With the door opening leading forward, the upper guide rail of the car door is accessible to the person waiting on the floor for the car coming from below, while for the car occupant, the upper guide rail of the landing door becomes accessible for the car landing from above.

The guide rail according to this embodiment offers in its interior the possibility of driving at its end with a roller guide shoes, which at the same time also the weight of the door panels can be worn. Of course, corresponding sliding guides are possible. The guide section 6h, 7a is arranged in the interior such that it can only be reached indirectly by the guide shoe, ie by the guide shoe 2 encompassing a wall section of the guide body 6. The Deflector 6g is therefore designed to be correspondingly short, so that a to the all sides enclosed inner 6i leading opening remains free.

It is important that care is taken that in practice no unilaterally held foreign body can penetrate into the universally enclosed interior 6i of the guide rail, that a danger arises. Therefore, the deflector is designed so that a kind of labyrinth arises between it and the covering surface 7b, which prevents a long, rigid object from penetrating so that it is in danger of not being rejected. In order to achieve a sufficient labyrinth effect, the overlap γ = 0, preferably> 10 mm, and optimally> 15 mm, to be measured in the vertical direction, as shown in FIG. 4, is selected. An overlap <0 is not permissible since this would mean that in practice it can not be ruled out with sufficient certainty that an elongated, rigid object easily penetrates the resulting gap beyond the deflector to the rear wall 6c into the guide rail and then clamped or sheared off.

Extremely advantageous is that the guide rail shown by Fig. 4 can also be used without changes as a bottom-side guide rail, the guide rail must be installed only rotated by 180 degrees about its longitudinal axis. Also, the guide shoes remain unchanged and are only appropriately rotated.

5 shows a third embodiment of the guide rail according to the invention. This is primarily intended as a bottom-side guide rail.

Another extremely advantageous variant of the guide rail according to the invention results when the guide rail gives a profile that is designed so that the guide rail both as the guide rail of FIG. 4 as well as the guide rail of FIG. 5 with guide shoes can work together. In this way you can with one and the same guide rail for different purposes (Above or below) guide devices are realized, which are optimally adapted to the individual application purpose of each resulting effort.

It should be noted at this point that the embodiments of the guide rail according to the invention shown in FIGS. 1 to 3 and 5, 6 can be used with appropriate rotation as a ceiling-side guide rail, especially for such door panels whose weight is intercepted by the bottom guide rail and therefore are only to lead at their top.

The ability to pry or deflect debris, as discussed, before being pinched or sheared between the cabin and the floor, depends on the angle of the slope and the coefficient of friction between the slope and the penetrated body. The smaller the angle of the slope with respect to the axis along which the elevator car moves, the greater the ability of the slope to prevent accidents. The angle is therefore preferably made less than or equal to 30 degrees. The same applies to the friction coefficient, which should be kept as low as possible. In the given case, it may even be advisable to provide the slope with friction-reducing means, such as a coating. Importantly, the slope is designed so that there is nowhere an edge in the recess 6f at which intruded objects could become caught before being rejected.

With such a deflector no 100% certainty for any conceivable case may be achieved. However, it is crucial that a practically sufficient degree of security is achieved, which manifests itself for example in that the guide rail for use in elevators, especially those with leading door opening, is officially approved.

The optional door apron 3 further contributes to the improvement of safety. It prevents under unfavorable circumstances from the flange 6e (see Fig. 1) objects can be detected and clamped.
