Definitions

  • the invention relates to a web-shaped button for motor vehicle built-in devices, which is resiliently mounted directly in an opening of a wall of a device housing and in which the grip surface of the key land facing outwards in the installed state has a large length / width ratio.
  • Such keys usually have to be provided in those cases in which, as for example EP-B 1 914 13 shows, the available surface on the front of relatively flat devices by various other actuating elements, by display means and by written or pictorial information is significantly restricted for the user.
  • the elongated button shape represents an optimal adaptation to the dimensions of a flat device, for example a device installed in the dashboard of a motor vehicle.
  • the available area can be better used and, at the same time, double actuation of adjacent buttons can be avoided. Another effect results from the fact that the range of actuation is increased in the case of web-shaped keys and the key search can thus be carried out less specifically. If such buttons are stored directly in the front wall of the device in question, there is a risk that they will jam in their storage as a result of the tilting moment that occurs when they are actuated, in particular when they are released.
  • buttons are customary to assign the buttons to the switches, which are usually attached to printed circuit boards, and to provide slots in the wall of the device housing with a relatively large amount of free space for the buttons to pass through without contact.
  • no fits are necessary, but it is also not applicable to all device concepts, in particular it considerably limits the scope for design on the front of a device.
  • the aesthetic effect arises, in the user due to the necessarily lower stability, in other words, the lateral mobility due to the lack of guidance of the respective key with such a key arrangement gives the impression of poor quality.
  • the entry of dust and water into the device is also facilitated, so that such solutions are only of limited suitability in the motor vehicle environment.
  • the task was to design a web-shaped button for motor vehicle built-in devices and to store them in a wall of a device housing in such a way that tilting is avoided and the impression of high quality is achieved with an acceptable manufacturing outlay.
  • the opening for the key web dipping into the housing wall can be significantly larger than the outer contours of the key web under these circumstances, so that the key web z. B. could also be painted. Also noteworthy is the low expenditure on components and form, as far as the key body and its storage are concerned, and, since wobbling and tilting of the key is avoided, a visible and noticeable ease of operation.
  • the tachograph 1 shown in FIG. 1 has on its front side a display 2, a cut 3 and web-shaped buttons 4 and 5 assigned to the drivers of a vehicle, the driving time of which is automatically recorded when the driver is actuated.
  • Diagram disks serving as recording media can be inserted and removed via the slot 3, or a printed document can be output of travel and working time data if the tachograph 1 is designed accordingly.
  • the keys 6, 7, 8 and 9 of a keypad 10 which are also designed as bridge keys, the keys 6 and 7 are used to display driving times or rest times of the respective driver on the display 2, while the keys 8 and 9 are used to pull in and out control a chart.
  • the key body 11 shown in perspective in FIG. 2 is formed from a key web 12, which is visible to the outside as a handle or actuating element, and a key shaft 13. With 14 and 15 guide pins are designated, which serve to receive the compression springs 16 and 17 of the key 18 (Fig. 3) and are formed with the greatest possible distance from each other on the outwardly rounded key web 12. At the free end of the key shaft 13, which is used to guide the key 18, latches 19 and 20 are molded resiliently. In order to achieve the longest possible storage of the key 18 in relation to the length of the key web 12, the bearing length of the key shaft 13 compared to the length of the key bar 12 is only reduced by the amount required for the attachment of the compression springs 16 and 17.
  • the one visible in FIG. 2 is designated by 21 - there are recesses which, as it were, double-digit storage of the push-button 18 and relatively narrow tolerances and thus an exact guidance between the push-button shaft 13 and a slot-shaped opening 23 allow.
  • the opening 23 is formed in an inwardly facing bearing projection 26 formed on the front wall 24 of the housing 25 of the tachograph 1. This can be formed as a continuous web or a rib on the wall 24, in particular if a plurality of keys 18 are to be arranged next to one another.
  • Fig. 3 it can also be seen that in the bearing projection 26, the pins 14 and 15 and the compression springs 16 and 17 associated with them, stepped through bores 27 and 28 are provided. Washers 29 and 30 secure the compression springs 16 and 17 against jamming in the respective, not used for guiding the button 18, unspecified clearance between the pins 14 and 15 and the through holes 27 and 28.
  • the button 4 are assigned to the compression springs 16 and 17 blind holes 31 and 32.
  • the guide pins 33, 34 are designed to be shorter in order to ensure the required key travel and are rounded in a suitable manner in order to enable the compression springs 16 and 17 to move undisturbed.
  • the button 18 is installed in a simple manner by pushing on the compression springs 16 and 17 and, if appropriate, the washers on the guide pins 14, 15 or 33, 34 and inserting them into the opening 23 and locking them with the wall 24.
