Description

The invention relates to a marking device in an elevator installation, which is referred to below as a marking device.

The object of the invention is in particular to provide a device which simplifies the assembly and / or maintenance of an elevator component. In particular, this device should facilitate the alignment and / or finding or detecting components of an elevator installation. The object is achieved by a marking device with the features of claim 1 and by a marking method with the features of claim 5. Advantageous embodiments and further developments of the invention can be taken from the subclaims.

EP 1 295 839 A1 discloses a marking device according to the preamble of claim 1 and a marking method according to the preamble of claim 5.

A marking device is proposed, which comprises at least one light emission unit which emits a light beam which is provided for generating at least one marking on an object present in the elevator installation. A "marking" is to be understood in particular a light mark, which is preferably visible by reflection of the light beam on said object, wherein the object may preferably be an elevator component or an auxiliary device.

On the one hand, the marking-ie the light mark-can mark a reference position which serves, for example, for positioning at least one elevator component which is to be adjusted after coarse assembly, or whose position must be checked during maintenance of the elevator installation. The marking has the function of a positioning mark. A "reference position" is to be understood in particular a position, starting from which a desired position of at least one elevator component can be advantageously determined. A "positioning" of an elevator component is intended in particular to be understood to mean an arrangement of the elevator component in a specific position or an orientation of the elevator component in a specific position relative to at least one other elevator component-ie to a reference element.

On the other hand, the marking may be used to identify at least one elevator component to be set and / or to be checked and / or serviced and / or mounted. In other words, during assembly and in particular during maintenance of the elevator installation, markings within the elevator installation can be effected by means of at least one light beam which can be adjusted in its direction, which mark or indicate the elevator components to be serviced or adjusted. As a result, assembly and maintenance processes can be organized in such a way that they can be carried out without error even by less experienced personnel.

With an embodiment of the marking device according to the invention, simple maintenance and / or installation of an elevator component can be achieved. In particular, an elevator component of a shaft door can be arranged precisely relative to a reference element of an elevator car, whereby in particular a low noise development, for example when opening elevator doors, can be achieved. In particular, a comfortable maintainability and in particular a comfortable working position for a fitter can be achieved, for example because a considerable distance can be present between an elevator component to be adjusted and a reference element. Furthermore, maintenance errors can be avoided and maintenance efficiency can be increased by pointing with an adjustable beam of light onto the elevator components to be serviced or tested. A particularly high maintenance or assembly efficiency can be achieved if the light emission unit marks two or more elevator components to be serviced and / or mounted according to a maintenance or installation program in succession with a light beam.

The markings are preferably present as temporary positioning markings or as markings which do not exist in an off state of the marking device according to the invention.

At least one elevator device is provided for fixing and positioning the marking device in the elevator installation. A "lift device" should be understood in particular to mean a part of a complete elevator installation to which a marking device is attached or which is provided and configured for the attachment of a marking device. Such an elevator device may have a fastening unit, with which the marking device on the elevator device is fixed. An elevator device may be in the form of an elevator shaft device or in the form of an elevator car device. The term "elevator shaft device" should be understood to mean, in particular, an elevator device which is part of an elevator shaft and / or is arranged or fixed on an elevator shaft. An "elevator car device" should be understood to mean, in particular, an elevator device which is formed by an elevator car or is part of an elevator car or is attached to an elevator car. An elevator device or a fastening unit present on the elevator device may comprise a positioning device which facilitates the positioning or adjustment of the marking device on the elevator device. A "positioning device" may include, for example, mechanical stops, at least one pivoting device, at least one clamping device, color markings, scales, etc. An elevator device may comprise a housing which forms at least one receiving area in which the marking device is at least partially arranged. In this way, a protected and secure arrangement of the marking device can be achieved.

In the case of fixing the marking device to an elevator car device, this elevator car device is formed by a car door fighter of the car door. This is particularly advantageous in maintenance and / or assembly, in which elevator components - in particular coupling means - are positioned on shaft doors, which are provided for coupling a shaft door leaf with a car door leaf. A "coupling" between a shaft door leaf and a car door leaf is to be understood in particular as a mechanical connection between a shaft door leaf and the car door leaf, which transmits an opening or closing movement of the car door leaf to a corresponding landing door leaf when the elevator car is facing a shaft door.

The light emission unit preferably has at least one laser for generating the light beam. Thus, a precise marking and accurate positioning of the elevator components to be positioned can be achieved. In addition, elevator components remote from the light emission unit can be characterized by the use of a laser.

Advantageously, the marking device has at least one preferably exchangeable beam shaping means which influences the light beam so that a particularly expedient optical marking can be achieved. A particularly informative optical marking can be achieved if the marking device has at least one optical lens and / or one lens prism as beam-shaping means. Thus, for example, the light beam can be spread in one or two planes such that a straight line or two straight lines perpendicular to one another can be marked on the object to be marked by the spread light beam.

In a preferred embodiment of the invention, the marking device has at least one fastening means, which is designed as a magnet. Thus, a simple attachment of the marking device, for example, to a reference element of the elevator system can be achieved.

Advantageously, the marking device has at least one battery and / or a rechargeable battery, whereby a simple power supply for a freely movable in the elevator installation marking device can be achieved.

Characterized in that the marking device has a power supply, a reliable power supply, such as the recharging of the battery can be achieved.

A precise positioning of the light emission unit can be achieved if the marking device has at least one adjustment means. Preferably, the adjusting means is designed as a screw, whereby a stepless adjustability can be achieved.

Furthermore, it is proposed that the marking device has at least one positioning unit with at least one angled portion for positioning the marking device. With such a positioning unit, an accurate positioning of the marking device can be achieved.

Advantageously, the marking device at least two light sources, whereby a more flexible usability can be achieved. In particular, a comfortable maintainability be achieved. In particular, several objects present in the elevator installation can be marked simultaneously.

Advantageously, the marking device has at least one bearing unit which movably supports the light emission unit. In this case, the term "movably mounted" should in particular be understood to mean that the light emission unit is designed to be movable in an assembled state relative to at least one component of the marking device. As a result, a flexible usability of the marking device can be achieved. A structurally simple design can be achieved if the bearing unit rotatably supports the light emission unit.

Furthermore, a marking method is proposed in which a marking device and an elevator device according to the above description are used, and in which marking method at least one elevator component or the intended mounting location of at least one elevator component is marked by at least one light beam. With such a method, easy maintenance and / or installation of an elevator component can be achieved. In particular, a component of a hoistway door can be arranged precisely relative to an element of an elevator car device, whereby in particular a low noise development, in particular in the case of opening and closing of elevator doors, can be achieved.

Advantageously, at least one desired position of at least one elevator component is marked in the marking method. This allows a simple and accurate positioning of the elevator component can be achieved during installation or maintenance of the elevator system.

According to a further refinement of the marking method, at least one elevator component already installed, to be adjusted and / or to be checked and / or serviced, and / or the mounting location of at least one elevator component to be mounted are marked in the sense of a marking. In this way, for example, elevator components to be serviced in accordance with a work plan, or the elevator components to be installed can be marked one after the other. This can be used to ensure that every scheduled operation is executed, wherein in each case the correct elevator component is adjusted or each elevator component to be installed is installed at the intended mounting location. In particular, it is also possible to achieve a lower expenditure of time for the installation or maintenance of the elevator installation.

Furthermore, a marking method is proposed in which at least one elevator component, which is a part of a shaft door, is marked with a positioning mark and in which a fitter located in an elevator car positions this elevator component through an open cabin door with the aid of the positioning mark. As a result, a comfortable positioning can be achieved.

In addition, a marking method is proposed in which an elevator component which is a part of a hoistway door is marked by at least one positioning mark generated by at least one light beam and in which a fitter located on a roof of an elevator car device is the elevator component positioned by the positioning mark. In this way, easy maintainability and / or mountability can be achieved. In particular, maintenance and / or assembly of an elevator component, which is a part of a topmost shaft door of an elevator installation, can be carried out in a simple manner.

It is also proposed that before positioning an elevator component with the elevator car, a position is approached in which the car door of the elevator car is offset in height from the corresponding shaft door. As a result, a comfortable maintenance and / or installation position can be achieved for the fitter. In particular, if the elevator component to be adjusted is a coupling means attached to a shaft door which is to be aligned relative to a carrier device attached to the car door, a car position can be selected in which a fitter standing in the elevator car passes through the opened cabin door comfortable working height can adjust the coupling means. The setting is carried out using a marker that is generated by an attached to the cabin door fighter of the elevator car marking device, wherein the elevator car is positioned so that the car door, for example, about a

Meters, above the corresponding shaft door.

Fig. 1 shows a view from the interior of an elevator car (not shown here) on a car door 42 with two partially opened cabin door wings 44, 45 and on a shaft door arranged behind 46 with closed shaft door wings 48, 50. On the cabin door leaves 44 are two skid-shaped cabin door-side coupling parts 52, 54th attached, which belong to a driver 55. In addition, an elevator car 56 belonging to the elevator car 5 is shown, which is formed by the car door fighter 43 of the car door 42 and carries a marking device 1 according to the invention. The car door 42 also includes two door posts 96, which form part of a cabin door frame with the cabin door fighter 43. The marking device 1 comprises a light emission unit 10 with a laser 24 which generates a vertically directed light beam 76. The marking device is positioned so that the position of the light beam 76 coincides in the horizontal direction with the position in which the center of the driver 55 is located when the car door leaves 44 assumes its closed position. In a certain operation, the marking device 1 generates a mark 12 on an object detected by the light beam (FIG. Fig. 2 ) in the form of a light mark. The marker 12 is formed as a positioning mark 14 and serves in the illustrated embodiment for positioning a bay door-side coupling means 38 with two shaft door rollers 18, 20 relative to the cabin door side coupling members 52, 54th

Fig. 2 shows the said bay door-side coupling means 38 in an enlarged view.

The cabin door-side coupling parts 52, 54 are connected to the car door leaf 44 and both have substantially the shape of a vertically oriented runner ( Fig. 1 and 4 ). During an opening or closing operation of the elevator doors, the cabin door-side coupling parts 52, 54 move synchronously with the cabin door wing 44.
The bay-side coupling means 38 with the two shaft door rollers 18, 20 is mounted on a shaft door 50 of the shaft door 46 and forms a car door shaft door coupling with the cabin door side coupling parts 52, 54 when the car door and a corresponding shaft door face each other at the same level. To open each of the elevator car opposite the shaft door, the distance between the two cabin door side coupling parts 52 and 54 is increased, so that they press against the shaft door rollers 18, 20 of the bay door side coupling means 38. On the one hand, thereby the shaft door side coupling means 38 in a clockwise direction rotated, whereby a connected to the bay door side coupling means 38 locking hook 15.1 lowered and thus a landing door lock is unlocked. Such a bay door lock is formed in that when the shaft door is closed, the locking hook 15.1 connected to the bay door-side coupling means engages with a locking stop 17 which is firmly connected to the shaft door fighter 47 of the shaft door 46 ( Fig. 2 ). On the other hand, causes the aforementioned increase in the distance between the two cabin door side coupling members 52 and 54 a form-fitting, horizontal play-free coupling between these coupling parts and the shaft door rollers 18, 20 of the bay door side coupling means 38 and thus between the car door leaf 44 and the shaft door panel 50th A bay door side coupling part 15th and the hoistway door rollers 18, 20 together form the above-mentioned bay door-side coupling means 38 which is rotatably but non-displaceably mounted on the shaft door 50 on an axle 21.

On the basis of the positioning mark 14, which makes a desired position recognizable, an installer, which is located in the elevator car, the bay door side coupling means 38 comfortably position by the bay door side coupling means 38 in a certain position relative to the position of the cabin door side coupling parts 52 and 54 given reference position. Before the arrangement or positioning of the bay door-side coupling means 38 can be carried out, the elevator car is moved to a position in which the car door 42 is offset relative to the corresponding shaft door 46 in the vertical direction ( Fig. 1 ). This ensures that the bay door-side coupling means 38 to be positioned is located during the positioning process on a comfortable for the person standing in the elevator car mechanic working height.

If the elevator car with the car door 42 and with the elevator car device 56 moves in the vertical direction 58 to the car door position corresponding to the car door position 46, then the cabin door side coupling parts 52, 54 travel between the car door rollers 18, 20 of the bay door side coupling means 38 one. If a stop of the elevator car device 56 is provided on the floor to which the hoistway door 46 belongs, then the cabin door side coupling parts 52, 54, after being moved in between the hoistway door rollers 18, 20, move from a drive-through position (FIG. Fig. 5 ), which they occupy while driving the elevator car, in opposite, horizontal directions in a coupling position ( Fig. 6 ), in which the cabin door-side coupling part 52 rests against the shaft door roller 18 and the cabin door-side coupling part 54 rests against the shaft door roller 20. In this case, as already mentioned above, the shaft door-side coupling means 38 is rotated with the locking hook 15.1 and thus the shaft door panel 50 unlocked and the cabin door panel 44 coupled to the shaft door panel 50.

The positioning mark 14, which is produced in particular during maintenance or assembly work on the bay door-side coupling means 38, is used to arrange and fasten the bay door-side coupling means 38 such that the positioning mark 14 is arranged in the middle between both shaft door rollers 18, 20 with respect to a horizontal direction 68. If both shaft door rollers 18, 20 have an equally large distance 74 from the light beam 76 or from the positioning mark 14 produced by the light beam of the light emission unit 10, then the bay door-side coupling means 38 is in its setpoint position. As a result, the hoistway door pulley 18 reaches and contacts the cabin door-side coupling part 52 and the hoistway door roller 20 simultaneously with moving the cabin door-side coupling parts from the drive-through position to the coupling position, thereby causing high noise, especially during this movement and especially when the hoistway door wings 48 are moved , 50 by means of the elevator components 52, 54, is avoided.

The cabin door side coupling parts 52, 54 are movably connected to the car door wing 44 of the car door 42. In the coupling position ( Fig. 6 ) These cabin door-side coupling parts 52, 54 with respect to a Breitenersteckungsrichtung 64 of the hoistway door 42, which is also a Breitenersteckungsrichtung the car door 42 of the elevator car 5, immovable relative to each other. In the coupling position ( Fig. 6 ) are the shaft door rollers 18, 20 with the cabin door side coupling parts 52, 54 with respect to a width direction 64 of the shaft door 46, ie mechanically positively coupled in the direction of opening or closing movement of the door. As a result, movements of the cabin door leaf 44 of the car door 42 (FIG. Fig. 4 ) of the elevator car 5 in the direction of the width direction 64 on the door wings 48, 50 of the shaft door 46 (FIG. Fig. 1 and 3 ) transfer. The width direction 64 extends horizontally in the direction of the opening or closing movement of the door leaf. Upon opening the car door leaves 44, 45 is due to the Entriegelns the landing door lock and due to the coupling between the car door leaf 44 and the shaft door 50 by the Cabin door side coupling parts 52, 54 and the bay door-side coupling means 38 also the shaft door 46 is opened. Here, the skid-shaped cabin door-side coupling parts 52, 54 act as entrainment device 55.

The marking device 1 serving at least for aligning the bay door-side coupling means 38 has a bearing unit 22 which rotatably supports the light-emitting unit 10 about an axis of rotation 80 which in a certain operating state runs horizontally ( Fig. 7 ). A lens prism 28 of the light emitting unit 10 spreads the light beam of the laser 24 to become a light beam 76 which propagates in a beam plane so as to mark a straight line on a flat surface perpendicular to the main direction of the light beam. The lens prism 28 forms a beam shaping means 142, which is preferably exchangeable. The light emission unit 10 can also be adjusted by exchanging the beam-shaping means 142, such that the light beam 76 generates two intersecting lines or a punctiform marking on a flat surface arranged at right angles to the main direction of the light beam. The marking device 1 has a leveling unit 148, which is designed as a tube level, and which is provided for a horizontal alignment of the marking device. For setting certain rotational positions of the light emission unit 10, which are each uniquely identified by a certain angle of rotation with respect to the axis of rotation 80, the marking device comprises a detent unit (not shown) which has at least four detent points. By means of the latching points is a fixing of the light emission unit 10 in rotational positions, which preferably emerge from rotations about ninety degrees apart about the rotation axis 80, feasible. In an operating position of the marking device aligned by means of the leveling unit 148, the light emitting unit 10 preferably radiates in the determined rotational positions in a horizontal direction or in a vertical direction.

Furthermore, the marking device fastening means 30, 82, 84, which are formed as magnets. Alternatively or additionally, the marking device may have fastening means for a form-fitting and / or non-positive and / or material-locking fastening of the marking device to an elevator car device or to an elevator shaft device. It is also possible to attach the marking device by means of a clamping device or by screwing, riveting and / or welding. The elevator car device 56 has a fixing unit 36 formed by the cabin door fighter 43 ( Fig. 8 and 9 ). The fastening unit 36 has a flat surface 86 which has only horizontal horizontal plane of extent. The marker attachment means 30, 82 rest on the surface 86 and attach the marker to the metalized fixture 36. The marker fastener 84 also abuts a further surface of the fixture assembly 36 which has a vertical surface extension direction (not shown). The fastening means 30, 82, 84 form an angling ( Fig. 7 ). The bend is provided for positioning the marking device. To power the laser 24, the marking device comprises a battery 88. In principle, the marking device can also have a power connection interface.

Furthermore, the marking device 1 has two adjustment screws 90, by means of which a fine adjustment of a direction of the light beam 76 can be carried out. In addition, a switch 92 for turning on the marking device is provided on an upper side of the marking device.

A light emission unit 10 mounted on an elevator car device 56 may further be positioned to create a mark during a maintenance or assembly operation by means of the spread-out, vertically directed light beam 76, by means of which, for example, the door posts 96 (FIG. Fig. 1 ) of the shaft door 46 parallel to the light beam 76 are aligned. Further, the light emitting unit 10 is rotatable by ninety degrees so that the main direction of the light beam corresponds to the horizontal direction. As a result, by means of the spread-out light beam, the shaft door fighter 47 and a guide rail 100 of the shaft door 46 can be marked and aligned horizontally (FIG. Fig. 3 ). In this position, a shaft door threshold 101 is also marked with a horizontally extending light mark, whereby the shaft door threshold is horizontally aligned. For this purpose, the elevator car (5) and thus the marking device are to be positioned on a suitable height for the marking of the respective elevator component.

Alternatively, the car door sill 103 of the car door 42 (FIG. Fig. 3 ) and the shaft door threshold 101 of the hoistway door 46 can be adjusted by means of the marking device by shaping the light beam 76 by a beam shaping means so that it propagates in one plane or in two planes of intersecting at right angles. In this case, the one beam plane 104 of the light beam 76, which is oriented vertically in its main direction, marks a straight line on at least one of said door thresholds (FIG. Fig. 8 ). To this straight line then one longitudinal edge of the two threshold is parallel to align.

Fig. 10 FIG. 12 shows a maintenance situation in which the light beam 76 emitted by the light emission unit propagates in a radiation plane 105 which extends perpendicular to a surface of a front side 154 of the shaft door leaf 50 and in the vertical direction. The beam plane 105 has an opening angle (spread angle) 152 which causes the light beam 76 to generate a positioning mark 14 on a flat surface of an elevator component (here, the bay door coupling part 15) parallel to the (here vertical) main direction of the light beam 76 extends. The positioning mark 14 has the shape of a line which runs parallel to the main direction (here in the vertical direction).

Fig. 11 shows a maintenance situation in which the light beam 76 is formed by a beam shaping means so that it propagates in two perpendicularly crossing beam planes 104, 105. In this way, marking lines can be produced on planar surfaces of elevator components which extend essentially parallel to the main direction of the light beam 76 and parallel to one of the beam planes 104, 105. In addition, with it, as in Fig. 11 shown, for example, the end surfaces 106 of the shaft door rollers 18, 20 are set parallel to the beam plane 104 of the light beam 76.

As in Fig. 12 and 13 1, the light emission unit 10 of the marking device 1 for positioning elevator components (here, the coupling part 15 and the hoistway door rollers 18, 20 of the bay door side coupling means 38) can also project the light beam 76 upward in the vertical direction. The marking device 1 with the light emission unit 10 is preferably fixed on the cabin door fighter 43 of the elevator car 5 serving as the elevator cage device 56. An upwardly directed light beam is particularly advantageous if the shaft door 46 to be adjusted is that which is assigned to the uppermost part of the elevator shaft and therefore an adjustment of said elevator components 15, 18, 20 can not be performed by the fitter out of the elevator car 5. In this case, the fitter turns to perform the said settings on the roof of the elevator car 5, wherein the elevator car 5 is moved to a position in which the car door 42 relative to the Shaft door 46 is offset so far down that the fitter can easily position the bay door-side coupling means 38 on the basis of the upward light beam 76. In this situation, a light beam 76 with two planes of intersecting at right angles can also be used ( Fig. 13 ).

In a particularly advantageous embodiment of the marking device or of the marking method according to the invention, the marking device contains a light emission unit which can emit a light beam in the opposite direction. Thus, it is no longer necessary to pivot the light emission unit by half a turn in order to apply the light beam in the upward direction wiw also in the downward direction.

Fig. 14 shows the marking device in an operating situation in which the light emission unit 10, the light beam 76, which here forms a beam plane, radiating upward in a vertical direction.

Fig. 15 shows the marking device in a situation in which the light emitting unit 10, the light beam 76, which here forms two perpendicularly intersecting beam planes, also radiates upward in a vertical direction.

In principle, it is also conceivable that the marking device has further light emission units which simultaneously mark desired positions of components to be positioned. Such components can be, for example, the shaft door threshold, door posts of the shaft door 46 or the car door 42 and / or guide rails (not shown) of the elevator car 5.

Furthermore, the marking device can be arranged at other locations of the elevator car 5 in order to identify and / or align one of the many elevator components present in an elevator shaft. In addition, it is conceivable that with the aid of the marking device, a vertical position of the elevator car 5, for example by means of a laser distance measurement, is determined.

In the Fig. 16 to 19 Alternative embodiments are shown. Substantially identical components, features and functions are basically numbered by the same reference numerals. To distinguish the embodiments, however, are the Reference numerals of the embodiments in the Fig. 16 to 19 the letters "a", "b" etc. added. The following description is essentially limited to the differences from the embodiment in the Fig. 1 to 15 , wherein with respect to the same components, features and functions on the description of the embodiment in the Fig. 1 to 15 can be referenced.

Fig. 16 shows an alternative embodiment of a marking device 1 a, which has three adjustment screws 90a. Each of the adjustment screws 90a has in each case an end region 108a which, for example, on the surface 86 of the cabin door fighter 43 (FIG. Fig. 9 ) is arranged. In at least two of the three adjustment screws 90a, the end portion 108a is formed by a magnet. The marking device also has a bearing unit 22a which supports a bearing means 109a of the marking device rotatably about a rotation axis 160a, wherein the rotation axis 160a extends horizontally in the operating state shown. The bearing means 109a can be locked by means of a locking means 121a in a specific rotational position with respect to rotations about the axis of rotation 160a. A holding means 111 a is rotatably supported by the bearing means 109 a about an axis of rotation 117 a. The holding means 111a receives a weight of a light emitting unit 10a of the marking device and stores the light emitting unit 10a translationally displaceable between two stops 113a, 115a. A center of mass 119a is disposed at an operating position in the vertical direction below the rotation axis 117a and thereby determines a position of the light emission unit 10a freely rotatably supported about the rotation axis 117a. Alternatively, of course, a blocking device may be present, with which the rotation of the holding means 111 a and thus the light emitting unit 10 a can be blocked around the rotation axis 117 a in a desired position.

The laser 24a is designed as a laser diode. Further, the light emitting unit 10a has a lens 26a which is formed as a cross lens and determines a shape of a cross-shaped light beam 76a. The lens 26a forms a beam shaping means 142a. The marking device 1 a comprises a leveling unit 148 a. The leveling unit 148a is formed by a circular level.

Fig. 17 shows an elevator shaft device designed as a shaft door fighter 47b of a shaft door 46b with a holding device 123b, which is provided for supporting and fixing a fixedly to be attached in the elevator shaft marking device.

The holding device 123b has positioning marks 125b which constitute a positioning device 32b for positioning the marking device. If the marking device is positioned on the holder device 123b or on the door holder, the positioning of elevator components in the elevator shaft and also on the elevator cage with respect to the position of the shaft door is possible. Optionally, a fine adjustment of the position of the marking device is required beforehand, which can be done by a displacement of the marking device along a width direction of extension 64b of the shaft door 46b.

Fig. 18 shows an elevator car 5c belonging to the elevator car 5c, which is formed as part of a car door fighter 43c. The elevator car device 56c has a holder device 123c provided as a holder for a marking device. On the cabin door fighter 43c are mounted positioning marks 125c which constitute a positioning device 32c for positioning the marking device. If the marking device is positioned, positioning of elevator components with respect to the position of the elevator car 5c or the cabin door side coupling parts 52c and 54c is possible. In particular, a marking device fixed to the elevator car device 56c enables marking and alignment of elevator components such as the bay door side coupling parts 15 with the shaft door rollers 18, 20 on the landing door wings 50b (FIG. Fig. 17 ). Optionally, for a precise positioning of the elevator components a fine adjustment of the marking device is required, by a displacement of the marking device along a width direction 129c of the car door 42c of the elevator car 5 can be made,

Fig. 19 shows how Fig. 1 a view from the interior of an elevator car (not shown here) on a car door 42d with two partially open cabin door panels 44d, 45d and on a shaft door arranged behind 46d with closed shaft door panels 48, 50, with an alternative embodiment of a marking device. In addition to the already known light emission unit 10d for positioning the bay door-side coupling means 38d, this marking device comprises three further light emission units 10.1d, 10.2d, 10.3d, which serve in particular to mark elevator components in the area of the car door 42d and the shaft doors 46d opposite the car door respectively to show such elevator components, so they are not overlooked or forgotten during a maintenance process. The light-emitting units 10.1d, 10.2d, 10.3d each contain a laser (not shown) and are fixed to a support 135d which is mounted on a cabin door fighter 43d serving as an elevator car device 56d. The support 135d thus forms a fastening unit 36d for the light emission units 10.1d, 10.2d, 10.3d, whereby it is preferably easy to assemble or disassemble in order to be used in various elevator installations. Of course, such a support with the light emission units fixed thereto can also be permanently installed in an elevator installation.
In a maintenance or assembly operation, the light emission unit 10.1 d marks a cable 137d which moves a car door leaf 44d of the car door 42d during an opening or closing movement of the elevator doors. The light emission unit 10.1 d points the fitter on the rope 137d, so that it checks the condition of the rope.
Another light emitting unit 10.2d marks a compression spring 138 which determines the rope tension of the rope 137d. The light beam 76 of the light emitting unit 10.2d marks the compression spring to alert the installer to check the condition of the spring and to adjust the spring length of the compression spring to ensure a certain rope tension.
A third light emission unit 10.3d points to an electrical safety contact 139d whose function is to be checked during a maintenance operation. The safety contact 139d must conduct the low voltage current when the associated hoistway door panel 50d of the hoistway door 46d is closed.
It is also conceivable that at least one of the light emission units 10.1d, 10.2d, 10.3d effects a positioning mark for positioning at least one elevator component in at least one operating operation.

Furthermore, it is conceivable that the light emission units 10.1d, 10.2d, 10.3d carry out labeling or marking processes one after the other, ie. H. the individual light emission units are activated in succession by means of a control unit according to an assembly or maintenance plan.

Marking devices according to the invention having a light emission unit or having a plurality of light emission units can be fixedly or temporarily installed at the most varied locations of an elevator installation in order to position elevator components with respect to a reference element or at mounting locations during assembly or maintenance operations elevator components or already installed elevator components.

For assembly and maintenance purposes marking devices could be used, in which a light emission unit is pivotable about at least two axes, wherein the pivoting movements are carried out by means of controllable and controllable positioning motors. This makes it possible to mark a plurality of mounting locations and / or position markers sequentially according to an assembly or maintenance schedule with a light beam quickly and accurately. Thus, the workload can be minimized and achieve a low probability of error. A possible further development of the invention consists in designing the laser present in the light emission unit as a distance measuring laser in order to obtain additional adjustment possibilities for positioning components in elevator installations.
