The roller mechanism may have a rotary (8) drum which can be pretensioned by spiral springs (23) towards its pivot axle (20). The pivot axle of a locking piece (22) can be clamped in any angular position.

Description

The invention relates to an elevator with an elevator car in a shaft that is open at least on one side, a covering being attached to the open side, which at least temporarily hides the view into the shaft.

Such panoramic elevators, directed towards the outside or towards an interior, are excellently suited as architectural elements for the design of building facades or courtyards and at the same time represent an eye-catcher for people who are in their surroundings.

A panoramic elevator is known from EP 0 585 123 A1, in which an elevator car runs in an elevator shaft glazed to the outside. This elevator car has an observation window that gives passengers a clear view of the surroundings, and it is equipped in a conventional manner with suspension ropes, hanging cables, counterweight and other system components necessary for operating an elevator. Since these parts of the system are visible from the outside due to the transparent shaft glazing and, moreover, they appear to be uncoordinated relative movements, they can impair the overall aesthetic impression of a building facade. EP 0 585 123 A1 therefore has the task of making the parts of the system necessary for operating the aforementioned panorama elevator, which are disruptive to its decorative appearance, invisible from the outside and without obstructing the view through the observation window. For this purpose, the glazing of the elevator shaft is coated with a liquid crystal layer and divided quasi-continuously in the vertical direction into segments which can be controlled either by the application of a suitable electrical voltage in the transparent or the opaque state. This liquid crystal coating is then controlled in synchronism with the cabin movement so that it - and so that the shaft glazing - in the area of the elevator car or the observation window is transparent, but opaque in all other shaft areas. This ensures a clear view through the observation window even when the cabin is moving. On the other hand, disruptive system parts such as drive parts, suspension cables, suspension cables, counterweights etc. are not visible from the outside, so that they cannot impair the external appearance of a panoramic elevator.

Accordingly, it is the object of the proposed invention to propose an elevator in which the area of the elevator shaft can be used by itself or in combination with the cabin for information and advertising purposes. The invention enables the attachment of a large and variable information and advertisement.

The object is achieved according to the invention with the means as characterized in the independent claim. Advantageous further developments are specified in the dependent claims.

The advantages achieved by the application according to the application essentially result from the fact that the shaft areas of panorama elevators generally have the dimensions required for large-area displays and are places of great importance due to the continuous movement of the elevator cars.

Another advantage can be seen in the fact that the cabin and shaft area can be combined to form an integrating whole for the purposes of information and advertising, thereby making the display versatile and versatile.

Another advantage is that the shaft display realized with the application according to the application can be changed at short notice by only the roller blind is replaced, which is quick and easy at any time. For this purpose, the elevator is moved into the shaft foot or in the shaft head, the roll-up poster is thus rolled up automatically and the roll-up / roll-off device including the rolled-up roll-up plate is extended and removed, for example by means of a cable pull. The installations in the shaft foot or in the shaft head, such as pillow block bearings, anti-rotation devices, double-disc coupling, etc., are designed for vertical assembly and disassembly of the reel / unwind device. In the same way, but in reverse order, a new roller blind with another information and advertisement is installed and unrolled in the elevator shaft. It has also proven to be advantageous that the elements of the application according to the application, namely the roll poster, the brackets on the cabin and the roll-up / roll-off device in the shaft foot or in the shaft head are essentially function-related and are therefore - in the same design - for one can be used in a wide range of applications, as it can result from structural changes or changed lighting conditions. For the different design variants of panorama elevators, a few individual parts, which are produced in standard sizes, can therefore be used. This results in the advantage of simple production and an uncomplicated disposition of the material requirements. Such an information and advertising facility has flexibility in use and freedom in design that cannot be achieved with customized facilities. Finally, the rolling poster rolling up and down with the movements of the cabin is an information and advertising medium that becomes an unmistakable eye-catcher due to its movements in the elevator shaft. Such information and advertising in motion arouses keen interest and is very well received. This applies in particular to an open elevator shaft in a heavily frequented interior or to an elevator shaft that opens up to the outside.

The invention is explained below with reference to the description and the drawing in its application as a large-area and variable information and advertising display for an elevator with a shaft opening towards an inner courtyard, the same elements being provided with the same reference symbols in the figures. However, the device shown here can generally also be used for panoramic lifts opening out into the open if the elevator shafts are glazed or the roll-up poster is wind-permeable.

FIG. 1 illustrates the structure and disposition of the roller blind elevator according to the application, two roller blind elevators A and B being shown side by side in the embodiment shown for better illustration of the innovation or the basic idea: the roller blind elevator A with a roller blind 1 from below and the roller blind elevator B with a roller blind 2 from above. A roller blind elevator A, B accordingly consists of the combination of an elevator, in particular a panoramic elevator, with a roller blind 1, 2 serving for information and advertising.

In the roller blind elevator A, the elevator is designed as a panoramic elevator with an elevator shaft 4, which is shown as a steel frame 3 and is open to an inner courtyard, in which an elevator car 5 is moved in a known manner by a drive (not shown further) through a traction sheave with a carrying rope and counterweight . Such a blind elevator A is such. B. attached to the facade of a building and is accessible from the inside. Those with E1, E2, E3 u. Stops marked E4 denote floors which are to be operated, the car 5 being located between floors E3 and E4 in the example shown. The roller blind 1 consists of a band-shaped, roll-up and roll-off roll-up poster 7 which is stretched on one end on the rotating drum 8 of a roll-up / roll-off device 9 and on the other hand has a holding device 10. In its preferred embodiment, the roll-up poster 7 is a film or a fabric made of a non-combustible or hardly combustible plastic. The reeling / unrolling device 9 is pre-tensioned in the reeling direction and will be explained later together with the holding device 10 with reference to FIGS. 2 and 3. In the present example of the roller blind elevator A, the automatic roll-up / roll-off device 9 is mounted in the shaft foot 11 and the holding device 10 is fastened to the underside 12 of the cabin, so that the rolling poster 7 extends in the lower shaft area 13 from the shaft foot 11 to the underside of the respective cabin position. When the elevator car 5 travels upwards, the band-shaped rolling poster 7 is pulled upwards by the pulling force of the car 5 on the cold device 10 and is continuously rolled on the winding / unwinding device 9 against its pretensioning force as required. On the other hand, when driving downward, the part of the rolling poster 7 released by the cabin 5 is automatically and continuously rolled up by the pretensioning force of the winding / unrolling device 9. This ensures that for each position of the elevator car 5, as well as for its transient states, the band-shaped rolling poster 7 between the reeling / unrolling device 9 in the shaft foot 11 and the holding device 10 on the underside 12 of the car is taut and verbal and Image information comes into its own.

The roller blind elevator B is basically constructed in the same way as the roller blind elevator A, although it is a hydraulic elevator in which the cabin 5 is moved by means of a hydraulic piston 6. Also, in the roller blind elevator B, the rolling / unrolling device 9 is mounted in the shaft head 14 and the holding device 10 is fastened to the upper side 15 of the cabin, so that the rolling poster 7 in the upper shaft area 16 thus extends from the shaft head 14 to the upper side 15 of the cabin. Furthermore, all considerations and representations for the roller blind elevator A apply in the same way to the roller blind elevator B.

Due to the constant upward and downward movements of the roller blind elevators A, B, the information and advertising message spread out below and above the cabins 5 is continuously moved up and down. rolled up. Since with the roller blind elevator A as well as with the roller blind elevator B the roller poster 7 only extends to the cabin underside 12 or to the cabin top 15, there is a clear view from the cabin 5 in both cases. The roller blind 1. 2 serving for information and advertising is impaired the functions of a panoramic elevator are therefore in no way: a roller blind elevator A, B is also a panoramic elevator without restriction.

FIG. 2 shows the roller blind according to the invention in its embodiment as a “roller blind from below” 1 for the information and advertising technology use of the lower shaft area 13 between the shaft foot 11 and a cabin position, for example E4. This "roller blind from below" 1 essentially consists of a band-shaped roller poster 7, which is fastened on one end to the revolving drum 8 of a reeling / unrolling device 9 mounted in the shaft foot 11, and on the other side is clamped on the underside 12 of the cabin by means of a holding device 10. The roll-up / roll-off device 9 is prestressed in the roll-up direction and thus ensures that the rolled-off part of the roll-up poster 7, which extends over the lower shaft area 13, for each cabin position and is taut even during every cabin movement. The band-shaped rolling poster 7 is preferably made as a film or fabric of a tear-resistant and bending-resistant, non-combustible or hardly combustible plastic and is further designed such that text and image information can be applied in the quality required for a large advertisement and in particular also in color. The dimensions of the roll poster 7 are freely adaptable to a wide range of different applications and can reach a weight of up to 1000 kg, for example with a width of 3 m and a length / height of 30 m, depending on the plastic and design used. If the rolling poster 7 is exposed to the wind, either a coarse-mesh fabric is used or holes or slits are specially made so that the wind load does not completely affect the rolling poster 7.

In the application example of FIG. 2, the reeling / unrolling device 9 is mounted in the shaft foot 11 and its rotatable axis of rotation 20 is supported on both sides in a split support 21 and clamped in any angular position by means of an anti-rotation device 22 shown in the following FIG. 3. Any assembly of the reeling / unrolling device 9 in the shaft head 14 would take place in the same way. The rolling poster 7 is fastened with its lower end to the rotating drum 8 by means of a band strip 24. The drum 8 is preferably rotatably supported on the axis of rotation 20 with roller bearings. Spiral springs 23 between the drum 8 and the axis of rotation 20 exert a torque on the drum 8, so that for each position of the cabin 5 there is always so much rolled up poster that the part of the rolled poster 7 covering the lower shaft area 13 is taut. Generation and function of this mechanical preload are explained in more detail with reference to FIG. 3.

In a simple embodiment, the holding device 10 at the other end of the rolling poster 7 can be a holding rod 25 which is drawn by loops at the upper end of the rolling poster 7 and which is fastened to the cabin floor 27 or the cabin frame 28 by means of brackets 26.

Since the panoramic elevators of FIG. 2 are roller blind elevators A, B, they have to be secured against blocking of the winding / unwinding device 9 in the two directions of rotation. If blocking in the rolling direction, the cabin 5 would be stopped abruptly by the roller poster 7 and - with the drive running - held, which could lead to damage to a roller blind elevator 1, 2, e.g. B. due to spinning of the traction sheave, a process that would not be technically acceptable. In its preferred embodiment, the holding device 10 is therefore additionally designed as a rolling device with a torque-actuated and sensor 29 monitored slip clutch 30. The slip clutch 30 is arranged between the bracket 26 and rotatable support rod 25. In normal operation, the slipping clutch 30 prevents the holding rod 25 from rotating. If the winding / unwinding device 9 blocks in the unwinding direction, its function is taken over by the holding device 10 in an emergency. For this purpose, a few meters of roll poster 7 or lighter extension tapes are wound onto the holding rod 25. The torque-actuated slip clutch 30 responds to the cold rod 25 when the torque is increased, and the holding device 10 releases so much roll poster 7 that the cabin 5 - controlled by the sensor 29 acting on the drive control - can be automatically moved to the next floor. As a safeguard when the reeling / unrolling device 9 is blocked in the reeling direction, a belt tension monitoring is provided, which is explained in more detail in FIG. 3.

FIG. 3 shows in a detailed representation the assembly of the reeling / unrolling device 9 in the shaft foot 11, as well as the elements for pretensioning it in the reeling direction and for monitoring it with regard to the reeling function.

In Fig. 3a, the roll-up / roll-off device 9 is mounted horizontally in the shaft foot 11 on both sides in two-part, vertical supports 21, the roller poster 7 attached on one end to the rotating drum 8 on the other side to the holding device 10 on the underside of the elevator car parked on the bottom floor E1 5 is performed.

To generate the pretension, the axis of rotation 20 of the reeling / unwinding device 9 is rotated in the reeling direction by means of a strongly reduced worm gear 38 acting via a double-disc clutch 37, relative to the rotating drum 8 fixed by the rolling poster 7, until the mutual pretensioning reaches the required value Has. Then the axis of rotation 20 is fixed by means of the anti-rotation devices 22 on both sides in the angular position that corresponds to the required pretension. If desired, the worm gear 38 can be separated from the axis of rotation 20 of the winding / unwinding device 9 by means of the two-disc clutch 37.

In order to make it easier to replace the rolling poster 7 in the shaft foot 11, all the elements holding the axis of rotation 20, such as supports 21, anti-rotation devices 22 and double-disc coupling 37, are designed in such a way that the roll-up / unrolling device 9 with the rolling poster 7 is preferably in the vertical direction, for . B. can be extended and retracted with a cable.

It is also important for the good functioning of a roller blind elevator A, B that the roller billboard 7 is wound evenly and evenly on the rotating drum 8. For this purpose, the reeling / unwinding device 9 or its axis of rotation 20 is mounted horizontally and vertically in the shaft foot 11. For alignment in the horizontal direction, elongated holes 43 are provided, in which the fastening bolts 44 can be displaced transversely to the axis of rotation 20. For horizontal leveling, the elements which support the roll-up / roll-off device 9 horizontally are supported on composite anchors 39 which can be adjusted in the vertical direction in the shaft foot 11. After the vertical setting of these composite anchors 39, they are poured with concrete 40 and the horizontal leveling of the reeling / unrolling device 9 is thus fixed.

In addition to the securing of the roll-off function described in FIG. 2, another is shown in FIG. 3b safety-related measure, a belt tension monitoring is shown, as a safeguard against blocking of the winding / unwinding device 9 in the winding direction. If the roll-up function were blocked when the car 5 was moving downward, the roll-up poster 7 released by the downward movement of the car 5 would no longer be rolled up, but would pile up openly and uncontrollably in the shaft foot 11, thereby hindering the function of the blind elevator A and for people who staying in its surroundings is a hazard. To protect against blocking in the roll-up direction, the roll poster 7 is therefore not guided directly to the cabin 5, but rather via a deflection roller 36 mounted on compression springs 41 and monitored by the switch 42. The switch 42 can be a mechanical switch, an electronic proximity switch or any sensor that monitors the position of the deflection roller 36. If the roll-up function is blocked, the roll-up poster 7 loses its tension, as a result of which the switch 42 which monitors the deflection roll 36 opens and the elevator car 5 moves to the next floor E1, E2, ... via the drive control and thus a build-up of roll-up roll 7 which has not been rolled up Manhole base 11 prevented.

The same considerations apply mutatis mutandis to a roller blind elevator B with a roller blind from above 2, except that in this case the unrolled roller poster 7 would accumulate in the upper shaft area 16 or on the cabin 5. On the other hand, the deflection roller 36 required for the tape tension monitoring also serves as a roll-up aid in that, in cooperation with the horizontal and vertical alignment of the roll-up / roll-off device 20 via elongated holes 43 and composite anchors 39, the roll-up poster 7 is rolled up evenly and evenly. As an additional roll-up aid, the two lateral edge regions 45 of the revolving drum 8 are cambered towards the center thereof.

The invention is not limited to a roller blind elevator A or B according to FIG. 1. Rather, a panorama elevator can also be combined with both types of roller blinds, that is to say have a “roller blind from below” 1 and a “roller blind from above” 2 at the same time.

Furthermore, both roller blinds A and B are excellently suited for creating special lighting effects, be it through the special choice of materials for the roller billboard 7, through the use of colored or polarized light, neon tubes and lasers or through the use of specially coated glass on the cabin 5 and in the lower and upper shaft areas 13, 16.
