Method for positioning counter-drive means of a

Shaft door of an elevator system

description

The present invention relates to a method for Posi ^¬ tioning of counter-drive means, which are provided on a shaft door of an elevator system.

Elevator doors usually have a on-car vorgese ^¬ hene car door and provided on each floor hoistway doors. When driving off a floor through the car, both the car door and the corresponding landing door (then positioned behind the car door) must be opened and closed to allow passengers to get in or out of the car.

Usually, a car door has a drive by means of which it can be moved up and down. In order to avoid corresponding drives for each shaft door, the car door is formed with driving means or a driver mechanism which engages upon reaching a floor in corre ^¬ sponding counter-drive means of the shaft door, and this with up and moved. Spreizschwert- mechanisms are usually used here, as they are beispielswei ^¬ se described in EP 0 744 373 Bl. Especially with a so-called high-performance car door is essential to avoid rattling and wind noise at very fast speeds. Furthermore, such elevator doors should open and close as quickly as possible. Egg ne precise positioning of the drive means and the counter-engaging means to each other is essential in order to avoid such Ge ^¬ noises and to allow a rapid opening and closing of the door. Another device for carrying a landing door by an actuatable by a door drive car door for elevator systems is known from WO 2011/072891.

Conventionally, it is common Spreizschwert constructed as entrainment means, which is integrally ^¬ introduced at the car door, and designed as rollers Gegenmitnahmemit- tel which are provided at each shaft door to be positioned in the vicinity of the upper edges of the door. This allows an installer, the car roof of a desired positioning of the counter-entrainment means to adjust the relative discrimination Mitnahmemit ^¬ tel. This is usually done in that the car is moved to a position slightly below a stock ^¬ factory position, so that the provided on the car ^{¬ seen} expansion blade and provided on the shaft door rollers in which the spreader blade engages to take along the shaft door for the Fitter are visible at the same time. This procedure proves to be particularly favorable in that the Spreizschwert protrudes with its obe ^¬ ren end over the top edge of the car.

The installer does the position of Spreizschwertes in to ^¬ sammengefaltetem state, and knows also the Hubbe- Movement of the Spreizschwertwinkel the Spreizschwertes, from ge ^¬ folded in the driven apart coupling or final state. On the basis of this optical information, the installer is able to position serving as a counter-entrainment means rollers between which the Spreizschwert intended to engage, so that the Spreizschwertwinkel in APART ^¬ nandergefaltetem state in each case act on a roller, and thus couple car door and shaft door. Usually, in this case, the two rollers, optionally provided with further components of a coupling and locking mechanism, on a support plate, which is formed with slots. The elongated holes are in this case positioned before corre ^¬ sponding, formed in the shaft door threads, so that a desired displacement and fixation of the support plate with respect. The shaft door is possible using cooperating with the slots and the threads screws.

In this procedure, however, a positioning of the counter-drive means, in particular a carrier plate with two rollers, and the Spreizschwertes only in un ^¬ indirect environment of the upper edge of the shaft door or car door is possible. This means that the coupling of car door and landing door in the vicinity of the upper edge of the doors is done, resulting in a relatively strong and uneven torque load on the doors, especially in fast-opening and closing doors.

Furthermore, the safety effort to be operated is relatively high, since the work must be carried out from the car roof. Finally, such a mounting is considered relatively aufwen ^¬ dig, since the positioning of the rollers is done essentially by eye. This leads in practice re ^¬ regularly cause the position of the rollers or of the carrier plate Trä- must be readjusted, which is connected to a Multiple Dogs ^¬ chen method of the car.

EP 1 500 625 A1 describes a method in which the positioning of the rollers on the shaft door is effected by means of an application by a spreading angle.

The present invention aims at a simplified yet precise positioning of the counter-drive means with respect to the driving means of a coupling mechanism for the car door and shaft doors of an elevator system.

This object is achieved by a method having the ^features of patent claim 1.

With the method according to the invention, a fast and effective and at the same time precisely executable method for positioning entrainment means and Gegenmitnah- means to each other is provided. The method allows a largely free positioning of the ^¬ With bearing devices and counter-entrainment means on the car door or the shaft door. The automated and very precise Posi ^¬ tioning rattling noises while driving the elevator car, and during the opening and closing of the doors, can be minimized or avoided. It should be noted that the steps of the method according to the invention are not necessarily carried out in the order indicated. must be led. It is conceivable, for example, to swap the order of the steps of the method or moving the car into a floor position and the opening of the car door with one another, for example to move the car to the floor position with the car door already open. Also, for example, the fixing of the shaft door in the closed state can be carried out before the car is moved to the floor position or before the car door is opened. The provision of the counter-drive means with play can also take place, for example, before the method of the car is moved to the floor position or before the car door is opened or before the shaft door is locked in the closed state.

The term "floor position" is understood in particular the position of the car, in which an entry and exit of a person is readily possible. In particular, this term includes the normal Haltestellenpositi- on, in which the bottom of the car and the respective floor aligned flush with each other. However, the term includes also car positions slightly below or slightly above the normal Haltestellenpositi ^¬ on, for example ± 20-40cm. The term is intended in particular to encompass all car positions in which the driving means and the counter drive means are in operative connection with one another, in other words the car is in the coupling or unlocking zone. When the car is moved to the floor position, the driving means and the counter-driving means are in operative connection with one another under normal operating conditions brought. For example, the entrainment means can be introduced into the counter-drive means.

The car door can be opened while the shaft door is closed, for example, by manually decoupling the car door from the shaft door. For this purpose, for example, a control function may be provided, which brings the driving means out of engagement with the counter-driving means when positioning the car in the floor position. It is also possible to first open the shaft door together with the car door, and then only to close the shaft door again. Opening the car door can be done for example manually or by pressing the corresponding drive the car door.

A fixation of the shaft door in the closed state, for example, be accomplished manually by using appropriate blocking tools.

The counter-entrainment means provided on the shaft door can already be designed with play relative to the shaft door when the car is being driven into the floor position. However, it is also possible that the counter ^{takeaway means} when driving the car are attached without play to the car door, and a (for example, in-car interior) fitter the Gegenmitnahmemit- tel provides. The inventive method can thus be used for initial setting as well as for a post-insertion of the position of the counter-drive means. The re-closing of the car door may again manually, or SUC ^¬ gene by use of the car door drive. The pressing of the formed on the car door driving means for applying the counter-entrainment means substantially corresponds to the normal coupling operation of car door and landing door, wherein the drive means engaging in the counter-entrainment means can be to accomplish a firm Kopp ^¬ development between the two doors, so that accession de doors opened by the car door drive and ge ^¬ closed. Here, however, the counter-drive means are moved or brought due to their game in a desired position Po ^¬ tion on the shaft door. Under completion of the loading of the counter-entrainment means by the driving means, a disengagement again will be appreciated contacting the carrier means with respect to the Gegenmitnahmemit ^¬ tel, which in turn opening the car door is possible by keeping closed the shaft door.

The subsequent attachment of the counter-drive means on the shaft door can then be done by a (for example, inside the car) fitter. The fixation of the shaft door in the closed state can now be solved.

Advantageous embodiments of the invention are the subject of the dependent claims.

Expediently, the counter-drive means comprise two rollers spaced ^{apart from} one another, and the driving means between the rollers einbringbares Spreizschwert with two Spreizschwertwinkeln, the rollers are pushed by means of Ausei- nanderfahren the introduced between them Spreizschwert ^¬ angle in its desired position on the shaft door and secured in this position. Such entrainment means and counter-drive means prove to be particularly easy to adjust, and in terms of maintenance and wear as robust and reliable. Conveniently, the rollers have a fixed spacing from each other on a support plate, wherein the carrier ^¬ plate has at least one slot. By means of a ^¬ like mechanism, a displacement of a support plate with the rollers mounted thereon with respect to a manhole door by acting through a Spreizschwert in a simple manner possible. It should be noted that even a ^¬ Ver pushability and fixability of the rollers directly on a shaft door can be realized (ie in particular without a carrier disk). For this purpose, it is possible, for example, to form slots in the shaft door, in which or with respect to which the rollers can be positioned. It is also conceivable, the rollers with respect to a support plate displaceable aufestal ^¬ th to a stop. In this case, an application by means of Spreizschwertes initially a method of roles with respect to the support plate, and only after reaching the respective stops a displacement of the support plate with respect effect the landing door. This embodiment allows provision of the already shown coupling and entrainment function with an unlocking function using only two rollers. The unlocking function is used to lock a locking mechanism through which opening the landing door during normal operation of the elevator is not possible, as long as the car or the car door is not immediately behind the shaft door to unlock. In this case, it is appropriate roles to fi ^¬ Xieren temporarily during positioning method in their position after reaching the attacks. In this way it can be avoided that these rollers move during the removal of the expansion blade in the context of the positioning method, and thus possibly cause a displacement of the support plate.

According to a particularly preferred embodiment of the method according to the invention, at least one of the method steps is accomplished at least partially by a fitter (operator) located in the interior of the elevator car. In this way, the safety of the operator who had to be performed by the car roof of Ge ^¬ genüber conventional positioning method is significantly improved. The method according to the invention can also be carried out faster and at the same time more precisely than conventional methods. In this case, it is preferable to let all process steps, as listed in the main claim, be carried out by an operator, who is located inside the car.

To be particularly advantageous, the Gegenmitnah ^¬ memittel and / or the entrainment means to form at about half the height of the shaft door or car door. Due to the compared to conventional solutions uniform load both the counter-drive means by the driving means and the respective doors is also a wear against reduced known solutions, which maintenance can be reduced.

The inventive method allows for the first time training or arrangement of the driving means and / or the counter-drive means at about half the height of the car door or the shaft door. As a result, occurring when opening and closing the doors moments that act on the doors can be significantly reduced. By "about halfway up" is in particular a distance of 50-150 cm, in particular 100-150 cm, from a lower edge and / or upper edge of the car door or shaft door, or a positioning in an area up to 50cm above or below the half door height understood. For entrainment means designed as a spread angle, this means, in particular, that the middle region of the vertically extending expansion angle is positioned approximately halfway up the car door. Such positioning of the ^¬ With bearing devices and / or counter-entrainment means leads to egg ner particularly easy accessibility for an installer, which is located in the interior of the car.

Preferred embodiments of the invention will now be further explained with reference to the accompanying drawings. In this shows or show:

Figure 4 is a schematic flow diagram of a preferred

Embodiment of the present invention.

In the figures la, lb a preferred embodiment of a driving device, in which the method according to the present invention is executable, shown and designated 100 in total.

The device 100 is used to couple a car door with a shaft door of an elevator. Car door and shaft door are indicated in Figures la, lb only schematically by means of brackets and designated 80 and 90 respectively. By means of the coupling between the car door 80 and shaft door 90 provided by the device 100, only the car door 80 has to be formed with a door drive (not shown) which opens or closes the car door 80. Due to the coupling, no separate drive must be provided for the shaft door 90.

The device 100 has car door side two spreading ^¬ sword angle 110, which with bay door side ^¬ brought rollers 210 for coupling the car door and Shaft door cooperate, as described below. The Spreizschwertwinkel 110 thus provide entrainment ^¬ medium, and the rollers 210 counter-drive means in the context of the invention.

The device 100 has the car door side a spreading ^¬ schwertwinkel drive 101, which serves to couple the spreading ^¬ schwertwinkel 110 with the rollers 210. For this purpose, the expansion blade angles 110 are initially extended by means of the drive 101 in the direction of the shaft door between the rollers 210 (indicated by arrow P in FIG. 1a), and spread in this position (indicated by arrow Q in FIG. 1b). This extended and spread position is shown in Figure lb.

The described retraction and spreading of the Spreizschwertwinkel 110 causes the Spreizwertwinkel act on the respective rollers 210, and thus couple the car door and landing door with each other. In this state, the car door and landing door are coupled to each other via the coupling of spread angle 110 and rollers 210 such that opening or closing the car door 80 by means of a car door drive (not shown) leads to simultaneous opening or closing of the landing door 90 leads.

In order to release the coupling between car door and shaft door again, the process described must be reversed in reverse order, ie the Spreizschwert- angle 110 are folded again by means of the drive 101, and retracted into the positions shown in Figure la. An exact positioning of the rollers 210 with respect to the Spreizschwertwinkel 110 is of great importance. Namely, for example, the Spreizschwertwinkel not located 110 in the example illustrated in Figure la state symmetrical or centrally of the rollers 210 can occur when spreading the Spreizschwertwinkel an asymmetric or not gleichzei ^¬ term exposure of the rollers 210, which is elevated for example in a Noise pollution (rattling noise) or even in increased wear can be felt.

When installing an elevator system, therefore, the rollers 210 at the shaft door with respect to, the Spreizschwertwinkel 110 and the car door must be positioned as accurately as possible ^¬ . This is where the present invention begins.

In FIGS. 2 and 3, a preferred design possibility for realizing the invention is shown. It can be seen here that the rollers 210 are mounted here on a mounting plate 250 ^¬ . This mounting plate 250 is formed with a number of slots 252 (four such slots 252 are provided in the illustrated example). Through these slots 252 each screw 254 are feasible, which cooperate with corresponding threads 256 which are formed in the shaft door 90.

In the case of a loose, ie not tightened, introduction of the screws 254 in the thread 256 thus a displacement of the mounting plate 250 and thus the rollers 210 with respect. The shaft door 90 is provided. The So roles here have a game on the shaft door.

In the following, reference is also made to FIG. 4 for illustrating the method according to the invention.

For positioning the rollers 210 with respect to the spread angle 110, the car is first moved to a respective stop (floor position) (step 410). Subsequently, by the installer, the car doors (suitably made from the interior of the car) is opened (step 420), which in this case must not be coupled to the Schachttü ^¬ ren. Subsequently, the shaft doors 90 are fixed against being pushed ^open or moved during the following positioning operation (step 430).

It is also possible to first open the car door and coupled with this shaft door, to release the coupling and then close the shaft door again and to fix in the closed position.

To serving as counter-entrainment means rollers to be adjusted relative to the shaft door 90 or relative to the serving as entrainment means Spreizschwertwinkeln in its position 210 to be a game for the rollers to provide first the attachment screws dissolved 254 and expedient ^¬ ßigerweise hand firmly tightened again ( Step 440). By this means, the mounting plate 250 is relatively lightly force ^¬ expense to the shaft door 90 to move. At the same time it is ensured that after completion of the automatic Positioning the position of the mounting plate 250 can be retained ^¬ th, then the final attachment or adjustment of the position by firmly tightening the screws 254 to accomplish.

In this state of the loosened and tightened fastening screws 254, the car door 80 is first closed again by means of the car door drive (step 450). The (fixed) landing door remains closed. In this locked position, the car door 80 is held exclusively by means of the car door drive (operating position). It is important for accurate positioning that these operating position is held during the positio ^¬ nierungsverfahrens.

The automatic positioning of the mounting plate 250 with the rollers 210 provided thereon is now started. For this purpose, only the already described with reference to the figures la, lb coupling operation (extension and spreading of the Spreizschwertwinkel) started who ^¬ the (step 460), ie an actuation of the car door formed on the entrainment means for applying the GE genmitnahmemittel be performed. To illustrate, the positions of the Spreizschwertwinkel are shown schematically in Figure 2. In the drawings, the dotted lines the extended and non-spread position of Spreizschwertwinkel, while the one-dot chain ^¬ oriented lines illustrate the positions of the extended and spread Spreizschwertwinkel. In this position illustrated by dash-dotted lines, the Spreizschwertwinkel 110 act on the rollers 210, wherein in this state with not tightened Befestigungsschrau ^¬ ben 254 a corresponding displacement of the rollers 210 is effected by the action of the Spreizschwertwinkel 110, if the rollers 210 are not positioned exactly symmetrical with respect to the Spreizschwertwinkel.

After completion of this coupling process and an eventual ^¬ displacement of the mounting plate 250 by Beauf ^¬ impact of the rollers 210 by the Spreizschwertwinkel 110, the rollers 210 are positioned in their optimal or optimized position with respect. The Spreizschwertwinkel 110.

Then the shaft door 80 and the car door 90 are again decoupled (step 470) (ie, the loading of the counter-entrainment means is determined by the driving means been ^¬ det) and the decoupled car door again (eg ma ^¬ Nuell) opened (step 480). The mounting plate 250. befin ^¬ det now, as mentioned, in the optimal or desired position to a symmetrical and simultaneous acted upon deposition of the rollers with respect 210th of Spreizschwertwinkel to ensure any further coupling operations 110th This position can now be fixed by simply tightening the screws 254 (step 490). Finally, the fixed gear ^¬ tion of the shaft doors is released again (step 500). The positioning process is now complete and can be repeated for each additional floor.

Compared with conventional positioning methods, the solution according to the invention provides significant time savings, since the counter-drive means can already be moved to the desired position on the shaft door during the first ^loading or interaction with the entrainment means. Carrier and counter-drive means are optimally positioned to each other only because of their own interaction. The method according to the invention is also characterized by increased safety, since the entire positioning process can be carried out by an installer located inside the car.

With the solution according to the invention, it is in particular possible to arrange the counter-drive means, that is to say the rollers 210, on the shaft door approximately at half the height of the shaft door or the car door. By such a coupling at half the height of the doors to be coupled a faster subsequent opening or closing of the coupled doors is possible. Also thereby a more even load on the doors during opening or closing ensures slightest ^¬ tet. In the case of a conventional coupling in the vicinity of the upper edge of the doors act overall, especially in the region of the lower edge, relatively large moments on the individual doors.
