Title: DEVICE FOR OPENING AND / OR CLOSING A DOOR

description

The invention relates to a device for opening and / or closing a door.

Such devices are well known as overhead door closers or automatic door operators for all types of doors. In order to give the user of the door an indication of accessibility, safety aspects or path information, the prior art provides a separate, illuminated display, e.g. for escape routes, used. Another way to provide the user with information about accessibility or orientation is described in CH 671803. Here, a cavity is created in the door frame, in which an information unit such as a writing tablet is used. This has the disadvantage that the builder or architect must decide in the construction phase for this type of door frame, as a retrofit makes the replacement of the entire frame required. Another disadvantage is the fact that a used door closer or door drive is not directly coupled to the information unit.

It is therefore an object of the present invention to provide a device for opening and / or closing a door, which can be coupled to a display device and is inexpensive to manufacture.

This object is achieved in that a display device is arranged in or on the device for opening and / or closing a door.

BESTATIGUNGSKOPIE In a preferred embodiment, the display device is arranged in a housing of the device for opening and / or closing a door. Thus, an overhead door closer or an automatic drive can be equipped directly with the display device.

To connect the display device as a separate component with the device for opening and / or closing a door, has the advantage that a subsequent equipment of existing components can be used.

With the display device, it is possible to display fixed or changing text, numbers or graphic symbols. In the case of fixed text, for example, a door can be marked as "emergency exit." If the text is changing, information about accessibility, orientation, or other information can be conveyed, as well as numbers, symbols, and a combination of everything.

The structure of the display device comprising a cap, an optical module and a cover ensures a high flexibility with regard to the use of various optical components. If the display device is an integral part of the housing, then eliminates the cover, since their function is taken over by the housing.

The cover has a transparent front glass of translucent glass or plastic, so that a material combination of metal or plastic for the cover and glass or plastic for the windscreen low-priced cover is created.

The cover can be plugged, aufgeklippst, pushed or screwed onto the attachment, so that easy installation and accessibility for maintenance is guaranteed. An optical module consists in a variant essentially of an LED surface light, a light bar and a reflector. This allows a fixed text display to be achieved by illuminating a slide with letters, numbers and / or symbols from the LED area light. The film can be arranged both between and on a lens and the LED surface light.

In a further variant, the optical module consists essentially of an LCD display. This allows you to display almost any text, numbers or symbols. Long text can be displayed as a change or scrolling text. A controller provides the display of the programmed characters. The LCD display can of LED ^'s, which are arranged on a printed circuit board, in addition backlit.

A backlighting of the LCD display is achieved if a pane is arranged in front of the LCD display, which is illuminated by a light bar.

The optical module is comprised in a further variant of a fixed display, wherein a plurality of arranged on a printed circuit board ^LEDs illuminate a film from behind.

A very compact in depth arrangement for a fixed text display is achieved when using as an optical module a film based on the physical effect of electroluminescence. Since this film is very thin and can produce a high light output, it is particularly suitable for installation in the housing of a door drive.

Another standardized construction is achieved in that a holder and a frame enclose the optical module, wherein the holder is attached to the attachment. - A -

The display device is used in a overhead door closer or an automatic door operator, which are arranged on a swing door, sliding door, folding door, sliding swing door, room partition door or revolving door.

A coupling of the display device with the overhead door closer or the door drive allows an indication of the access state of the door.

Further advantageous embodiments will be apparent from the dependent claims.

Further details, features and advantages of the invention will become apparent from the following description of a preferred embodiment with reference to the drawings.

In the illustration, only the parts relevant here are shown, all other construction elements have been omitted for clarity.

Figure 1 shows an example of two door leaves 2 a sliding door with an associated door drive 1, which is mounted above the door 2 on a wall or facade. In or on the door drive 1, a display device 6 is arranged, which can represent a fixed or changing text, numbers or graphic symbols. As a display device 6 is not the signage or the attachment of letters, characters and symbols considered, but a display of fixed or alternating text that can be switched off or added, and optionally backlit from the inside. The display device 6 can not only be used on drives for automatic doors, e.g. Sliding doors, swing doors, folding doors, sliding swing doors, space-saving doors or revolving doors can be arranged, but also on mechanical or semi-automatic door closers for revolving doors. The display device 6 extends in this representation, for example, only over a part of the total length of the drive 1. It is of course possible to make the display device 6 larger, so that it extends substantially over the entire length of the drive 1.

Figure 2 shows a sectional view through a housing of an exemplary door drive 1, wherein the details of the drive for reasons of clarity are not shown. The door drive 1 is arranged in a housing 5, and fastened by means of fasteners 4, for example via a mounting plate 3 to an unspecified wall or door frame. On the front of the housing 5, the display device 6 as a standalone Diges module arranged and fixed. Alternatively, the display device 6 may also be an integral part of the housing 5, wherein the embodiment shown here can be variably adapted to the customer's wishes, since the display device can also be retrofitted.

The schematic structure of the display device 6 in FIGS. 3 to 7 is as follows: the door drive 1 is enclosed by the housing 5 to which the display device 6 is fastened. An attachment 9 is connected to the housing 5, or - if the display device 6 is an integral part of the housing 5 - arranged in the housing 5 of the door drive 1. The attachment 9 is ultimately the support to or with which the optical module is attached to or in the housing 5. Between the attachment 9 and a cover 7, an optical module 10 is used. The cover 7 is releasably secured to the attachment 9, e.g. stuck, peeled, etc.

Outwardly, the optical module 10 is covered by a windscreen 8, which may be made of glass or plastic, and is attached to or in the cover 7. If the display device 6 is an integral part of the housing 5, then the cover 7 is omitted, since the front screen 8 is arranged in the housing 5.

In this embodiment, the front screen 8 has bevelled edges, so that the connection to the cover 7 is designed like a dovetail groove and the front screen 8 is pushed laterally into the cover 7. A clamping piece 13 made of plastic or rubber fixes the windshield 8 in the cover 7. Here, any other type of positive or non-positive attachment between windscreen 8 and cover 7 is possible. Between the cover 7 and the attachment 9 a holder 11 is arranged with a frame 12 which receive the optical module 10. The optical module 10 of FIG. 3 is a fixed-text display which displays text, numbers or graphic representations once given. For this purpose, an LED surface light 17 is inserted or clamped within the holder 11 and the frame 12, which is irradiated from below with a light bar 15 with light. Alternatively, the LED area light 17 can also be irradiated laterally by the light bar 15. So that the light is conducted as completely as possible through the windshield 8, there is a reflector 16 between the LED surface light 17 and the holder 11, which guides the light in the direction of the windshield 8. As an alternative to the LED surface light 17, a pane can also be used, which also fulfills the function of a surface light. Between the LED surface light 17 and the frame 12, a lens 14 is arranged. A film 21 is arranged or clamped in this example between the LED surface light 17 and the lens 14. The film 21 may alternatively be arranged on the lens 14. With the film 21, a fixed text, a number or letter / number combination or a graphical representation is displayed in which the light bar 15 is turned on or off. A change of the text is only possible by changing the film 21.

The optical module 10 of FIG. 4 is a running or removable text display which displays various texts, numbers or graphic representations via an LCD display 20. For this purpose, a printed circuit board 18 is arranged within the holder 11 and the frame 12, which receives a plurality of LED ^' s 19 and thus backlit the LCD display 20. The printed circuit board 18 can be screwed to the attachment 9 via the holder 11. Also mounted on the circuit board 18 is a controller 22 so that changing text, numbers or graphics can be displayed. The optical module 10 of FIG. 5 is a fixed-text display which displays text, numbers or graphic representations once given. For this purpose, a disc 23 and a lens 14 is inserted or clamped within the holder 11 and the frame 12, which are irradiated from behind with LEDs ^' . The ^LEDs are arranged on a circuit board 18 which is in turn fixed to the bracket. 11 A film 21 is arranged or clamped between the disk 23 and the lens 14. The slide 21 displays a fixed text, a number or letter / number combination or a graphic representation in which the LED ^'s 19 are switched on or off. A change of the text is only possible by changing the film 21. In order to compensate for temperatures, although the diffuser 14 is fixed to the frame 12, the reflector 16 is fixed to the holder 11 with clamping pieces 13 made of plastic or rubber.

The optical module 10 of FIG. 6 is a running or removable text display which displays various texts, numbers or graphic representations via an LCD display 20. The LCD display 20 is additionally illuminated from the front. For this purpose, a disc 23 is inserted or clamped within the holder 11 and the frame 12, which is irradiated from below with a light bar 15 with light. The disc 23 in this embodiment has the function of a light guide or a surface light and can alternatively be irradiated laterally by the light bar 15. Between the disk 23 and the frame 12, a lens 14 may be arranged.

FIG. 7 shows a fixed-text display which displays text, numbers or graphic representations which have already been specified. For this purpose, a film 21 is inserted or clamped within the holder 11 and the frame 12. This film 21 consists of a so-called back-light film, in which a fixed text, a number or letter / Number combination or a graphic representation of a special pigment applied to the film 21. These pigments can be illuminated by electrical stimulation. These backlight films are based on the physical effect of electroluminescence, and in addition to the variation of the textual or graphic design, also allow different light effects, for example by assigning different light colors to different areas. This can be achieved by light filters or by the different electronic control of the pigments. A change of the text is only possible by changing the film 21. Depending on the embodiment, the film 21 may additionally be chambered by a support plate 24 and a disk 23 in order to ensure additional stability for large-area films 21. The film 21 may alternatively be arranged only with the windscreen 8 within the housing 5 of the door drive 1. The advantage of using these back-light foils is that very compact dimensions can be realized in the overall depth, and that the backlighting foil can be arranged in radii or around corners. Thus, especially in the case of revolving doors, the use of this back-light foil is possible on the front side on the round cover part of the revolving door. Likewise, a housing shape for the door drive with a directed to the ground radius or arc is possible to which adapts the backlighting foil. For a user of the door, as the distance to the door decreases, looking up to the drive becomes easier if he wants to read the text.

A coupling of the display device 6 with an overhead door closer or a door drive can allow the indication of the state of the door (open, closed, emergency exit, etc.), but also indicate the number of persons entered or other information for eg maintenance. LIST OF REFERENCE NUMBERS
