Description

The invention relates to a control panel for an elevator system and an elevator car with such a control panel.

In elevator systems, an elevator car moves into an elevator shaft between different floors (hallways) of a building to carry passengers. The interior of the elevator car typically has a control panel or so-called COP (Car Operating Panel) in its walls, usually in a side wall that is parallel to the entry/exit direction through the car door of the elevator car if the elevator car is rectangular or parallelepipedal cabin is. Such an arrangement of a control panel offers better accessibility because the control panel is closer to the entrance of the elevator car than a control panel on a side wall on which the handrails are normally mounted and have to be interrupted because of the COP. which is opposite the entrance or cabin door.

A disadvantage of conventional car panels can therefore be seen in the fact that passengers initially only have an undesired oblique view (e.g. <30°) of a control panel when entering an elevator car. In this case, visibility of the control panel and its more realistic color fidelity may be compromised, particularly when the control panel is a touchscreen or large-screen display. However, a display or screen usually only has a horizontal or vertical viewing angle range of up to 120° (in this application, all angles are defined in degrees) in order to be able to comfortably and correctly perceive content shown on it.

Another disadvantage of such an installation of control panels is, among other things, that the thickness or the interior space of the control panel, which is integrated into a side wall of the elevator car, is limited due to the thin wall thickness of the elevator car, which makes it difficult to use more and larger components to be integrated into the control panel and consequently to expand its functions.

There may therefore be a need to allow greater installation space for a control panel in an elevator car or to provide passengers with better visibility of the control panel without partially and disruptively reducing the usable inner surface, for example for passengers with a wheelchair.

Such a need may be met by the subject matter of any of the independent claims. Advantageous embodiments are defined in the dependent claims and the following description.

According to the invention, a control panel for an elevator installation is proposed, the control panel having at least one control panel and a housing. The control panel is provided for operating and/or controlling the elevator system, with the housing having an opening or recess in which the control panel is accommodated. The elevator system includes an elevator car, which forms a cuboid cavity with vertical inner edges. That is, the elevator car is considered a hollow block. The housing is designed for mounting the control panel in the elevator car in such a way that the control panel can be arranged along an inner edge of the cavity of the elevator car, whereby the control panel spans the inner edge or bridges the walls of the elevator car that close together at the inner edge. An inner edge is formed, for example, by a first wall that is parallel to the entry/exit direction through a car door of the elevator car and a second wall that is perpendicular to the first wall.

According to an advantageous embodiment of the invention, the control panel can have a flat, a convex or a concave surface. The convex or concave surface is understood as a surface curved outwards or inwards. The control panel is e.g. a touch screen. Alternatively or additionally, the control panel can include a display and/or at least one control element, such as floor selection buttons or other buttons such as pushbuttons, key switches, selector switches, emergency stop switches, etc. Compared to a conventional flat surface, a convex or concave surface has a larger area so that the control panel can accommodate more controls and/or more display area. For this purpose, a convex or concave control panel, in particular a touch screen, can be clearly seen anywhere in the elevator car. Thus, the visibility of the control panel for passengers in different positions in the elevator car can be maintained equally well and reliably.

According to a further advantageous embodiment of the invention, the control panel can be assigned essentially parallel to a geometric diagonal plane of the elevator car, the diagonal plane being parallel to the inner edge on which the control panel is arranged. In this context, the diagonal plane of the elevator car is understood to be a plane that runs through the center point and two opposite edges of the cuboid cavity formed by the elevator car. The control panel can thus form an included angle to the walls of the elevator car, the included angle having an angle of between 30° and 90°, because the control panel is flat but can also be concave or convex. There is usually an included angle of 45° between the control panel and the above-mentioned first or second wall of the elevator car. Since the control panel or control panel is no longer arranged parallel to the direction of entry/exit of the elevator car, passengers in the elevator car have a viewing angle of at least 30° onto the control panel. In other words, it is ensured that the directions in which the passengers are looking can lie within a horizontal viewing angle range (approx. up to 120°) of the control panel. A viewing angle denotes a perspective from which the control panel of the control panel is viewed, or a viewing direction that results from a passenger. The passengers can then comfortably perceive the control panel or content displayed on it.

Compared to a conventional control panel, which is fixed flat on a cabin wall, the control panel according to the invention is attached at an angle, e.g. at an angle of 45°, to two mutually orthogonal cabin walls. A control panel manufactured in this way has a thicker structure due to its prismatic shape, as a result of which a larger installation space is formed in the control panel. Preferably, the control panel is to be attached to an inner edge close to the cabin door. That is, the inner edge is formed by a front wall in which a car door of the elevator car is installed and a side wall that is, for example, perpendicular to the front wall. Therefore, no space is occupied on the side wall of the elevator car. If a control panel is additionally arranged on an inner edge of the elevator car, which is opposite the car door (e.g. two-sided car entrances), there is another advantage that the passengers can see the control panel immediately when entering the elevator car. A search scenario can then be avoided in which a passenger turns around in an elevator car in order to be able to find and operate a control panel.

According to a further advantageous embodiment of the invention, the housing has an upper and/or a lower cover, the upper or the lower cover having a substantially triangular shape or a shape in the shape of a sector of a circle. In this case, the control panel of the control panel is not arranged parallel but at an angle to the cabin walls, with the inclination of the control panel being chosen so that people can comfortably look at the control panel and operate it. In this case, the upper or the lower cover of the housing can form a convex cover for the control panel, as a result of which the inner installation space of the control panel is further increased. Furthermore, since dust does not easily accumulate on a convex top cover, cleaning work of the operation panel can be facilitated.

According to a further advantageous embodiment of the invention, the housing has at least one rear side which has an essentially rectangular or triangular surface. As an alternative, the back can form a convex or concave cover for the housing if this does not take up too much space in the elevator car. If the housing comprises two rear sides, they then form a right angle, a substantially right angle or an acute angle with one another.

The control panel should be on the inside of the cabin wall at a certain height. e.g. at least 80 cm above the cabin floor. Such a mounting height enables problem-free operation by disabled people (e.g. wheelchair users) or children, while also allowing normal standing users to operate normally. At the same time, it does not occupy any extra space on the cabin floor.

According to a further advantageous embodiment of the invention, the control panel can extend as far as the floor and/or the ceiling of the elevator car as needed and as desired. Such a design of the control panel facilitates wiring from the floor or from the ceiling of the elevator car directly into the control panel.

According to a further advantageous embodiment of the invention, the housing of the control panel--the rear side, the upper and lower cover--are formed or replaced at least in part or in part by the first and/or the second wall of the elevator car. I.e. on the one hand the material and the costs for the control panel can be saved, and on the other hand the weight of the entire control panel can also be reduced, such as in the case mentioned above that the control panel or the control panel extends to the floor and/or extends to the ceiling of the elevator car, the upper cover of the control panel can be formed by the floor of the elevator car and the lower cover of the control panel by the ceiling of the elevator car.

Furthermore, an elevator car is proposed, which has at least one control panel shown above or can be controlled by the control panel. Accordingly, an elevator installation is proposed which has at least one such elevator car.

If the elevator car has two car doors located opposite each other, a control panel can be placed next to each car door on an inside edge of the elevator car.

It is pointed out that some of the possible features and advantages of the invention herein with reference to different embodiments of the lighting device on the one hand and a method for illuminating an elevator shaft of an elevator installation on the other hand are described. A person skilled in the art recognizes that the features can be combined, adapted or exchanged in a suitable manner in order to arrive at further embodiments of the invention.

Embodiments of the invention are described below with reference to the accompanying drawings, neither the drawings nor the description being to be construed as limiting the invention.

In Fig.1 a cuboid elevator car 5 of an elevator system 2 is shown. In the elevator car 5, an operating panel 1 is arranged as a car operating panel (COP: Car Operating Panel) along an inner edge 12 of the cavity of the elevator car 5, as a result of which the operating panel 3 spans the inner edge 2 or the walls 13, 14 of the elevator car that close to the inner edge 12 5 bridged. The inner edge 12 is formed by a first wall 13 and a second wall 14 of the elevator car 5, which are orthogonal to each other. In this case, a control panel 3 of the control panel 1 is attached at an angle of 45° to the cabin walls 13 and 14, so that passengers can easily look at the control panel 3 and operate it. In other words, the control panel 3 is essentially aligned parallel to a geometric diagonal of the elevator car 5 , the diagonal plane also being parallel to the inner edge 12 . This ensures that the passengers always have a good perspective when looking at the control panel 3 . Control panel 1 is preferred as in Fig.1a shown placed on an inner edge 12 of the elevator car 5 next to the car door 11 . Fig.1b represents an alternative embodiment, from which it can be seen that the control panel 1, if necessary, also opposite the cabin door 11 at a other inner edge 12 between a side wall 13 and the rear wall 14 of the elevator car 1 can be located. The control panel 1 should be fixed at a height such that the bottom of the control panel 1 is at least 80 cm away from the car floor, whereby the floor space of the elevator car 5 is not reduced.

1c and 1d each represent further exemplary embodiments that the control panel 1 or the control panel 3 can extend continuously up to the cabin floor and to the cabin ceiling of the elevator car 5, with in Fig.1c is shown that the control panel 1 is located next to the cabin door 11 between a side wall 13 and the front wall 14, while Fig.1d shows a control panel 1 which is positioned askew or offset relative to the cabin door 11 between a side wall 13 and the rear wall 14 .

The fact that the control panel 1 is arranged in a corner of the elevator car 5 automatically results in a thicker construction of the finished control panel 1, regardless of the wall thickness of the elevator car 5. A large installation space is thus created in the control panel 1, but no higher production costs are involved and no important space in the elevator car - i.e. close to the center of the elevator car - required extra.

Fig.2 shows a top view of a cuboid cavity formed by the elevator car 5 . Several passengers 18 are in this cavity. A display or screen for passengers should normally have a horizontal viewing angle range of up to approximately 120°, for example. Since the control panel 1 is no longer completely on a side wall 13 of the elevator car 5, all passengers 18, whose faces are normally towards the car door 11 during the elevator ride, have a viewing direction 19 of the control panel 1, which is obviously in the horizontal viewing angle range of the control panel 3 lies. Even the passenger 18 who is standing next to the side wall 13 has a viewing angle of at least 45° on the control panel 3. With a control panel 1 arranged in this way, there is always a good viewing angle on the control panel 3 for the passengers 18, so that the Passengers 18 can look comfortably at the control panel 3 or reliably perceive the information displayed on it.

Fig.3 shows that the control panel 1 has at least one control panel 3 and a housing 4, the control panel 1 being arranged between two cabin walls 13 and 14. The housing 4 consists of, for example, two rectangular sides and two triangular lids 9a and 9b, and the operation panel 3 is accommodated in an opening of the housing 4. FIG. For fastening the control panel 1, the housing 4 expediently comprises, for example, a mounting frame 16 at a right angle, as a result of which the control panel 1 is mounted in a holder 17 on the cabin walls 13 and 14 engaged. The holder 17 forms a continuous rail, with the control panel 1 being displaceable up or down along the rail.

The housing 4 can of course also be constructed in one piece with cabin walls, such as at least one rear side 10 of the housing 4 can be formed or replaced by a cabin wall. Then the housing 4 , the control panel 3 and the cabin wall together enclose an installation space for the control panel 1 .

Fig.4 shows further exemplary embodiments of the control panel 1. It shows Figure 4a a control panel 1 with a flat control panel 3, and Fig.4b shows a control panel 1 with a convex control panel 3. The control panel 3 includes a display 6b and at least one control element 6c, such as floor selection buttons, door control buttons, alarm button, etc. The control panel 3 can also have a concave surface. The upper or the lower cover 9a, 9b of the housing 4 can have an essentially triangular shape or a shape in the shape of a sector of a circle. In Figures 4c and 4d a control panel 1 is shown in each case, the control panel 3 of which is a large touchscreen 6a. The touch screen 6a can have a convex and a concave surface. Of course, the touch screen 6a can be a flat touch screen.

In the Fig.5 control panels 1 shown have compared to the control panels 1 in Fig.4 a convex top lid 9a. In addition, a control panel 1, which in Fig.5a is shown, a concave control panel 3 with a touch screen 6a, and another control panel 1 in Fig.5b includes a convex control panel 3 with a display 6b and several controls 6c. The control panel 1 is better protected from dust by the convex cover 9a, cleaning work on the control panel 1 can consequently be facilitated. In addition, since the internal installation space of the operation panel 1 is increased, more or larger components can be installed in the operation panel 1. In order to create the installation space even larger, the lower cover 9b of the control panel 1 can also be curved outwards, provided that not much space in the interior of the elevator car 5 is required.

As an alternative to the control panel 1 being placed at a certain height above the cabin floor, the control panel 1 can be constructed in such a way that its volume shrinks from top to bottom. Then the control panel 3 presents, for example, an inverted trapezoidal or triangular front. Since the lower part of the control panel 1 is narrower than its upper part, the entire control panel 1 can be placed lower. 6a and 6b each show a control panel 1, the housing of which consists of only three triangular or three circular sector-shaped sides, ie the two rear sides of the housing 4 close together and consequently form a sharp or dull tip, so that the control panel 3 of such a control panel 1 has an inclination to the cabin floor.

Finally, it should be noted that terms such as "comprising," "comprising," etc. do not exclude other elements or steps, and terms such as "a" or "an" do not exclude a plurality. Furthermore, it should be pointed out that features or steps that have been described with reference to one of the above exemplary embodiments can also be used in combination with other features or steps of other exemplary embodiments described above. Any reference signs in the claims should not be construed as limiting.
