Definitions

  • the present invention concerns an elevator with a car operating panel to register elevator calls
  • the car panel could also be used as a maintenance tool.
  • Multi-button input the user interface of the elevator was a one-action machine-man interface. With a 10 digits-keypad solution the user interface of the elevator becomes a two-action machine-man interface, since, for example, to place a call to the floors 12 or -1, the user must push two buttons sequentially.
  • optical acknowledgment Because one button serves for different inputs, the optical acknowledgment of a pressed button and of a registered call would be equivocal.
  • Said car operating panel can preferably be used without adding special components and exhibits also preferably a maintenance interface to change the elevator parameters.
  • Such a car operating panel exhibits, however, the disadvantages to be expensive, not user-friendly, complex to be configured, not esthetically attractive. Furthermore, this apparatus exhibits a difficult fabrication and assembly and cannot be produced using well-established components. The advantages for logistic are therefore lost.
  • This apparatus is, furthermore, not conform to the norms concerning handicapped people, since blind people cannot recognize by tact the floor numbers on the keyboard. According to the norms EN 81-70, these requirements must be fulfilled for elevator push buttons: an operating force between 2.5 and 5 N, an operating and registration feedback and floor numbers in relief with a minimal height of 0.8 mm.
  • a car operating panel which solves this problem according to the present invention, is claimed in independent claim 1.
  • This claim concerns an elevator with a car operating panel, comprising push buttons corresponding to floors of a building, wherein said push buttons act on switch contacts registering elevator calls and wherein said push buttons are reversibly mountable on the switch contacts by position lock or frictional contact or glued joint.
  • Said Push buttons are parts of the car operating panels, which can place an elevator call, when pushed for example by the human finger of an elevator user.
  • switch contacts are meant freely configurable, when the floor to which they correspond and to which they place a call, can be freely changed and programmed.
  • the set of combinations switch contact-floor constitutes a specified configuration, which can be set up for example by a service man at the moment of the installation of the elevator in a building, on the ground of the number of floors exhibited by said building. If the switch contacts correspond to real and physical floor in a building, they are configured as active or activated. If the switch contacts do not correspond to any real and physical floor in the building, they are configured as inactive or deactivated.
  • a blank element is a part of the car operating panel, which is not marked by any indication of a floor number or concerning another elevator function. It is preferably not movable and does not allow then the activation of the switch contact underlying it.
  • Push buttons can be lighted-on, when a light source generates light making them distinguishable from the other push buttons. This does not make sense with a conventional 10 digits-keypad solution.
  • the invention as set out in claim 1 exhibits the advantages, that the claimed car operating panel can be freely configured according to the building in which is mounted in a very user-friendly way, without the need of expensive components or complex operations. Since the configuration is carried out only by mounting by position lock or frictional contact or glued joint determined push buttons of the car operating panel, corresponding to the active switch contacts, said configuration can be carried out in a very fast, elegant and time non-consuming way. Additional mechanical components are not required. The configuration can always be carried out on the same type of car operating panel, maintaining in such a way all logistic advantages offered by a unique factory produced car operating panel. An additional advantage is that in case of failure of a push button said defective push button can be easily replaced, with no need to demount the entire car operating panel or replace it entirely.
  • said push buttons are mountable on the switch contacts by snap action or by screws.
  • said switch contacts are freely configurable to correspond to floors of a building according to a specified configuration.
  • This preferred embodiment exhibits the advantage, that each combination and order of push buttons placing calls to a determined floor can be achieved, with no restriction of any type.
  • push buttons marked with a floor number are mounted on the switch contacts activated to place elevator calls to said floor and inactive switch contacts are covered by a blank element.
  • This preferred embodiment exhibits the advantage that inactive switch contacts not only are disabled to place calls to the elevator control, but are also not perceived at all by the elevator users, not generating thereby any type of confusion or annoyance.
  • the push buttons comprise a frame, which is mountable by snap action.
  • This preferred embodiment exhibits the advantage that while snapping the push buttons onto the switch contacts, no elevator call is mistakenly placed by exerting pressure onto the switch contacts.
  • the car operating panel exhibits a 10 digits-keypad consisting in a symmetric matrix of 12 configurable touch sensitive buttons arranged in 3 columns and 4 lines.
  • This embodiment exhibits the advantage to use standard components already present nowadays in the market.
  • a button arrangement is provided comprised in a floor range from -3 to 8 and blank elements cover the inactive switch contacts.
  • This embodiment exhibits the advantage to be suited to the most spread buildings and to the most common floor configurations, which occur in the market.
  • the push buttons when actuated to register an elevator call, are configured to be lighted on, in a manner that the acknowledgement of the elevator call is visible.
  • the registration and acknowledgement of button is visible in a destination indicator above the button part unit or in a separate display.
  • This embodiment exhibits the advantage that the intuitive perception of the call acknowledgment is very fast and clear in the human brain of the elevator user.
  • buttons are lighted on by a backlight generated by LED's.
  • This embodiment exhibits the advantage that the light generating devices are very small and inexpensive.
  • the light acknowledging a registered elevator call blinks with a predetermined intermittency.
  • This embodiment exhibits the advantage that the intuitive perception of the call placement is increased.
  • the switch contacts are configurable to correspond to elevator operations and/or functions to be carried out and/or activated during maintenance or service.
  • This embodiment exhibits the advantage that an additional maintenance man-elevator interface is not required and place and costs can be saved.
  • the push buttons are provided with Braille signs in relief indicating the floors assigned to the buttons, in such a way that they are recognizable by a blind person.
  • This embodiment exhibits the advantage that the elevator installation is made compatible with the norms relating to handicapped people.
  • push buttons for an elevator car operating panel are provided, said push buttons being mountable on the switch contacts of the elevator car operating panel by snap action or by screws.
  • This embodiment exhibits the advantage that different types of push buttons can be provided by different suppliers and sold for example in the form of elevator button kits, which can be easily produced and bought in the market and which can be easily mounted during an elevator installation or supplied to the customers and elevator users themselves in view of an elevator upgrade or modernization.
  • Fig. 1 shows a car operating panel 1 known in the state of the art.
  • the car operating panel exhibits a keypad 2, which, in this example, is characterized by 10 digits arranged in a predefined spatial order (10 digits-keypad).
  • the keypad exhibits push buttons 6, which are used to place elevator calls to the building floors.
  • the push buttons are movable in the horizontal direction in order to place the calls and are firmly and undetachably mounted onto switch contacts, for example by means of gluing or welding. They act on the switch contacts in order to place the elevator calls.
  • a frame 7 surrounds the push buttons. This frame is firmly und undetachably fixed to the base 8 of the car operating panel, for example by means of gluing or welding.
  • the floors corresponding to the push buttons are indicated by black markings indelibly stamped or laser-printed on the push buttons.
  • the switch contacts are arranged behind the areas corresponding to the push buttons to produce an electrical signal, which is then generated through the touching of a human finger.
  • the car operating panel can detect elevator calls placed by a user and transmit them to the elevator control.
  • the operating panel is also provided with a position indicator 3, which displays at which floor the elevator cage is traveling at a specific instant.
  • a destination indicator 4 is also usually provided, which shows all calls which have been placed and must be still served. No button acknowledgement is possible for the placed calls.
  • Auxiliary signs 5 are preferably provided, which point out special conditions of the elevator equipment, such as alarm, emergency and similar auxiliary indications. The alarm and emergency symbols are not visible in the normal use. Therefore lift users are not made frightened about this possibility.
  • This car operating panel exhibits evident advantages from the point of view of the logistic, since a unique operating panel in this form can be produced industrially and introduced everywhere in different types of buildings, with dramatic cost advantages.
  • This car operating panel exhibits, however, the disadvantage, that the 10 digits (0 to 9) are always displayed on the keypad, since they have been indelibly stamped or laser printed on the push button surface and the push buttons cannot be easily replaced.
  • the push buttons are firmly and undetachably connected with the switch contacts, while the frame is firmly and undetachably connected with the base.
  • the 10 digits are, for example, also displayed, when the car operating panel is mounted in a building with only two floors, in which the digits ranging from three to nine would be unnecessary, which brings confusion and complains from the side of the concerned customers and users.
  • PCB circuit board
  • Fig. 2 shows a preferred embodiment of the present invention, which solves all cited problems.
  • the push buttons 6 of the keypad 2 which correspond to floors which are effectively present in the building and which are therefore active, are snapped onto the switch contacts 9 by means of a snap-in push button frame 7.
  • the push button comprises then a movable central part, which is used to place elevator calls, and an external frame part 7, which is fix and is used to snap the push buttons on the switch contacts.
  • the active push buttons are therefore easily installable and replaceable.
  • the snapping action of this preferred embodiment can be replaced by any other suitable reversible positive lock mounting system of the push buttons.
  • buttons and blank elements can be mounted with screws or by any other suitable frictional connection system.
  • a glued joint can be also imagined between the push buttons and the switch contacts, whereby the push buttons can be easily and rapidly demounted by an increase of the temperature or by the action of ultrasounds, which make the glued joint weaker.
  • the car operating panel is therefore freely configurable and can be customized to the building configuration in a very user-friendly and inexpensive way.
  • the car operating panel is therefore totally configurable and can be customized to each building and required floor configuration.
  • the configuration operations are very simple and do not require any special electronic hardware or software programs to be executed.
  • the configuration can be carried out manually by any person in a very fast, user-friendly and inexpensive way by using well-established factory produced components.
  • the service man can define which switch contacts have to be activated by entering the lowest floor offset of the building.
  • the elevator control knows how many floors are in the building and can activate automatically the necessary switch contacts.
  • kits of elevator push buttons can be produced and sold independently from the fabrication and installation of an elevator. These kits can be provided to maintenance personal, customers and even elevator users, so that they can personalize, upgrade or modernize their elevator installations corresponding to their wishes with no need of complex and expensive technical operations.
  • buttons actuated to register an elevator call are configured to be lighted on with blue light generated by LEDs placed behind the buttons, in a manner that the acknowledgement of the elevator call is visible.
  • the elevator call is also acknowledged by a blinking with a pre-determined intermittency of the light.
  • An audible signal could be provided as well.
  • Fig. 3 shows a car operating panel according to the present invention as installed in a building with floors ranging from -1 to 3. With this car operating panel different button arrangements are possible inside a floor range from -3 to 8. A maximum of 12 stops can be achieved.
  • This car operating panel is, however, especially suited for the following floor ranges, which are the most common in our cities: -1 to 2, -1 to 3, -1 to 4, 0 to 2, 0 to 3, 0 to 4, -2 to 2, -2 to 3, -2 to 4, -3 to 8.
  • buttons In case of public buildings, in which elevator installations must meet norms relating to handicapped people, the push buttons must exhibit Braille signs in relief indicating the floors assigned to the buttons, in such a way that they are recognizable also by a blind person.
  • An operating force between 2.5 and 5 N, an operating and registration feedback and floor numbers in relief with a minimal height of 0.8 mm are also compulsory requirements.
  • the switch buttons of the car operating panel in Fig. 3 are configurable to correspond to elevator operations and functions to be carried out and activated during maintenance or service.
  • the maintenance interface is a classical 10 digits-keypad one and is used as input for the maintenance and configuration functions of the elevator.
  • a 10 digits-keypad kit of push buttons similar to that one displayed in Fig. 1 must be preferably provided to the maintenance personal, so that these supplied buttons can be snapped in and the configuration mode functions are then clearly evident to the service personal on the elevator-man interface of the keypad.
  • the 10 digits-keypad buttons are dismantled and then the switches are directly free for the programming/configuration mode. After configuration, the buttons are fixed again and the car operating panel is ready to use. Switches on PCB are marked with the 10 digits -keypad numbers, and no additional key pad unit tool for programming is needed.
